[0004] The present invention generally relates to systems and methods for a multi-functional power tool system, and in particular, a gutter cleaning system.

[0005] 2. Description of the Related Art

[0006] Tools are often designed to carry out a single function, and thus, an individual may need to purchase and maintain multiple tools, such as a tool for each task they may want to complete, where a tool may facilitate completion of the task. Further, some tasks are prohibitively dangerous for a user wishing to complete the task by themselves, such as gutter cleaning from the top of a ladder. A need exists for a tool that is capable of carrying out a single function, such as gutter cleaning, or multiple functions and may be operated at a distance from the user.

[0007] Provided herein is a multi-functional power tool system operable at a distance from a user, comprising an interchangeable functional module and a power base for mounting and powering the functional module. The tool may enable use of a single base piece that may provide power, handling, and the like, to which modules with different functions may be attached.

The gear may be at least one of a planetary cluster, worm and worm gear, bevel gear, internal gear, spur gear, and right angle gear. The mechanical mechanism connected to the output of the gearbox may provide the appropriate motion to the end effecter. The mechanism may be at least one of a crankshaft and connecting rod, a bell crank to provide reciprocating motion, a geneva wheel to provide intermittent motion, and a mechanical modifier of the rotational motion. An electrical mechanism connected to the output of the gearbox may provide the appropriate motion to the end effecter. The electrical mechanism may be at least one of a solenoid or servo motor to effect on/off functions, a limit switch to stop and start aspects of the mechanical system within the tool, a sensor for controlling an end effecter of a functional module or for responding to the environment, a laser and a vision system. The power head may include a power take-off coupling, wherein the coupling provides a connection for a functional module to at least one of a gear motor and an electrical control element. The coupling may include an automatic speed selection feature that engages a speed selector mechanism to automatically match the output speed of the power head to the ideal input speed of the functional module. The selector mechanism may include a mechanically activated pushrod that moves a speed select lever of the power head to the chosen speed automatically by positioning a selector rod to the right length. The selector mechanism may include a sensor on the power head connection plate that identifies the functional module and makes the speed selection in the gearbox electromechanically. The gear motor may be operably connected to a power take-off coupling to provide a power input from the gear motor to a functional module.

The device 104 may have a point of attachment that may be compatible with a placement facility 174. For example, the device may have a threaded connection and the placement facility 174 may have a threaded end. The point of attachment may include a fastener 178, which may permit the removable or permanent attachment of the placement facility 174 or power base 160 to the device 104 in multiple orientations. For example, the fastener 178 may attach the device 104 to the placement facility 174 or power base 160 in an orientation permitting downward operation, upward operation, horizontal operation, and the like. The fasteners 178 may be disposed on a top, bottom, or side surface of the device 104. In embodiments, the fastener 178 may be a nut and bolt, a screw, a nail, a rivet, a magnet, an adhesive, a hook-and-loop, an interference locking system, a threaded connection, a sliding attachment, a hinge, a clamp, a tab, a spring-loaded attachment, a sleeve attachment, a snap-fit connection, a ball closure, discrete interlocks, a clasp, a clip, a zipper, a snap, a gasket, an O-ring type closure, a hook-and-eye, a spring-locking hinge, and the like.

The pivot 180 may be configured and disposed to permit a varying angle of the device 104 with respect to the placement facility 174, power base 160, gutter, user, and the like. The upper end of the placement facility 174 or power base 160 may be connected to the pivot 180. The placement facility 174 may be configured to allow the user to adapt its length to a wide range of roof/gutter heights, such as by telescoping, adding additional segments, allowing greater reach, and the like.

[0131] In some embodiments, the placement facility 174 or power base 160 and the device 104 may be formed as a single unit. For example, the device 104 may be integral with the placement facility 174 or power base 160.

[0132] In an embodiment, the gutter-cleaning device 104 may be connected to a power base 160. The power base 160 may allow for at least one element of the gutter cleaning device 104, such as an impeller transmission 130, an impeller drive facility 138, an energy storage facility 142, a transport motor 154, a transport transmission 158, transfer gears, power take-off couplings, control facility 168, and the like to be disposed within the power base 160, as further described herein. In embodiments, a fastener 178 may permit the permanent or removable attachment of the device 104 to the power base 160, as previously described herein. For example, the power base 160 may include a control facility 168, an ergonomic grip area, and an energy storage facility 142. In embodiments, the control facility 168 may be the only element not disposed within a gutter-cleaning device 104.

[0133] In operation, a process for using the system 102 may comprise the stages described below. The process, however, is exemplary only and not limiting. The process may be altered, such as by having stages added, removed, rearranged, and the like. A user may deploy the gutter-cleaning system 102 by lifting the device 104 attached to one end of a placement facility or power base 160 to rest in a gutter with a support guide/wheel 172 resting on an outer edge, a floor, or a wall of a gutter. The user may turn the system 102 on with the control facility 168. The user may maneuver the device 104 up and down the length of the gutter while it disposes of accumulated gutter debris. When cross braces may be encountered in the gutter, the forward and aft protruding impellers may clean under the brace but the user may have to lift the device 104 to the other side of the brace to continue cleaning. The connection point of the placement facility 174 or power base 160 may comprise a mirror to provide the user with an indication of the contents of the gutter on either side of the device 104. Once the gutter cleaning is completed, the user may turn off the system 102 with the control facility 168 or the system 102 may power down automatically after a pre-determined length of time, if a prohibitive level of moisture is detected, if the impellers become disengaged or stuck, and the like. The user may then lift or lower the system 102 of the gutter.

[0134] Referring to FIG. 3, by positioning certain functional elements within the power base 300, the power base 300 may be operable with a wide range of functional modules, including a gutter cleaning device as described above.

An electrical connector 342 of the power base 300 may be adapted to provide suitable electrical power and, optionally, control signals for driving the motor 302. The motor 302 may include a wire 344 with a first end and a second end, the first end being attached to the motor 302 and the second end 348 being adapted to connect to the electrical connector 342. The pole 330 may be a rigid telescoping pole with one or multiple segments. The pole 330 may include a quick release coupling 332 to adjust the telescoping pole segments. The pole 330 orientation may be modified to facilitate placement of the functional module at a desired location. The pole 330 may be housed within a lower pole segment 334 from which it may telescope outwards. The lower pole segment 334 may have a high friction hand grip surface. The lower pole segment 334 may comprise a handle 338. The handle 338 may be a separate component of the lower pole segment 334 or may be integral to it. The handle 338 may have a high friction hand grip surface, similar to or distinct from that of the lower pole segment 334. The handle 338 may be ergonomically shaped. A control switch 340 may be disposed on the lower pole segment 334. The control switch 340 may turn power on or off to the motor 302.

The power head 404 may be operably connected to a control module 408 by a wire 420 or some other electrical connection. The control module 408 may comprise a battery 410 which may provide power to the power base 400. Alternatively, the control module 408 may comprise other power means, such as a solar panel, an internal combustion engine, an electrical cord, and the like. The battery 410 may be removably connected to the power base 400 through a battery connection base 412. The control module 408 may comprise a handle 414. The handle 414 may have a high friction hand grip surface. A control switch 418 may be disposed on the control module 408. The control switch 418 may turn power on or off to the power head 404.

The power head may have a thread connection 422 for connecting to a complementary thread connection 424 on the control module 408. The thread connections 422, 424 may be either male or female. The thread connections 422, 424 may be industry standard connections, such as those used on a painting pole. Alternatively, the power head 404 may be attached to the control module 408 through any attachment means, such as a nut and bolt, a screw, a nail, a rivet, a magnet, an adhesive, a hook-and-loop, an interference locking system, a threaded connection, a sliding attachment, a hinge, a clamp, a tab, a spring-loaded attachment, a sleeve attachment, a snap-fit connection, a ball closure, discrete interlocks, a clasp, a clip, a zipper, a snap, a gasket, an O-ring type closure, a hook-and-eye, a spring-locking hinge, and the like. In an alternative to a direct attachment of the power head 404 to the control module 408, both the power head 404 and control module 408 may be attached to opposite ends of a pole 402, such as a painting pole, broom stick, some other off-the-shelf pole, and the like. For example, the power head 402 may have a female thread connection 422 to receive a male thread connection 428 from a pole 402. In the example, a control module 408 male thread connection 424 may connect with a female thread connection of the pole 402. The wire 420 connecting the power head 402 to the control module 408 may be disposed along the side of the pole, may coil around the pole, may thread through the center of the pole, and the like.

[0137] Referring to FIG. 5, a power base 500 for attachment of various functional modules, such as a gutter cleaning module, may comprise a segmented pole 502 with integrated electrical conductors and end electrical connections. The pole segments 502 may facilitate packaging and storage of the power base 500. The pole segments 502 may have connections on either end such that one end of the pole segment may have a connection complementary to an end of another pole segment 502. For example, the pole segments 502 may have a male thread connection 504 and a female thread connection 508 on either end of the pole segment 502. The thread connections 504, 508 may have coaxial connectors 510, 512 disposed within the connections 504, 508 to provide a continuous electrical connection between pole segments 502. An electrical conductor 514 internal to the pole segment may provide an electrical connection between the coaxial connectors 510, 512. When a pole segment 502 is connected to another pole segment 502, they may form a continuous electrical connection through the coaxial connectors 510, 512. In an embodiment, the power head 404 may be connected directly to the control module 520 through the threaded connections 504, 508. Alternatively, one or more pole segments 502 may be connected in between the power head 404 and control module 520.

The motor/gearbox pod 612 may be operably connected to a power take-off coupling 614 to provide a power input from the motor 612 to a functional module. In this way, any functional module may be attached to the power head 404 as the motor 612 may not be specifically paired with a functional module, but rather, may be operable with many different functional modules. In an embodiment, the power head 404 may comprise an articulated extensible pin actuator 618 driven by an electrical solenoid to effect on/off selection of module functions. In an embodiment, the power head 404 may comprise an articulated sliding pin actuator 620 driven by an electrical slide solenoid to effect analog mechanical input for module functions.

A manual speed change switch 640 on the gearbox 612 may be adaptable to different functional requirements of the various modules. For example, the switch 640 may control speed, direction, intensity, duration, timing, and the like.

[0140] Referring to FIG. 7, an enlarged view of the control module 700 is depicted. The control module 700 may have a handle 702. The handle 702 may have a high friction hand grip surface. The control module 700 may house a removable rechargeable battery 704 attachable to the control module 700 through a battery connection base 708. The battery 704 may be removable with a latch 710 for recharging.

[0141] Referring now to FIG. 31, the power tool system 3100 may be a tool system comprising a power base module 3104 of handle or control module, pole, and power head 3110 facilitating attachment of a wide range of tool attachments 3102. The base component comprises a pole 3108 and a detachable power head 3110 comprising a connection plate 3112 facilitating the attachment of a wide range of tools 3102. In an embodiment, the power head 3110 may be configured to provide primary mechanical power to the tool attachment 3102. The power head 3110 may be attached to the pole 3108 which may convey electrical power from an energy storage facility, such as a battery compartment, in the handle via conductors 3114, 3118 that may be routed inside or outside the pole. These electrical conductors 3114, 3118 may be controlled by switches in the handle or control module and may carry either power 3114 to the motor that may be of relatively high voltage and current, or electrical signals 3118 that provide informational content to electronics mechanisms that control the tool attachments 3102. The power head 3110 may comprise a high torque motor 3120 connected 3124 to a gearbox 3122 that may provide power to the tool attachments 3102 via a power take off shaft 3130. The gearbox may have multiple speeds 3128 with a selector mechanism 3132 that may be attached to a mechanical linkage 3134 that may have a connection at the tool attachment connection plate 3138. The electrical signals 3114, 3118 may be passed through wires 3140 that bypass the gear motor to contacts 3142 on the mating connection plate 3112 that may engage mating contacts 3158 on the connection plate 3144 of the tool attachment 3102.

[0142] The tool attachment 3102 may comprise three parts: the connection plate 3144, the tool body 3148 and the end effecter 3150 that accomplishes the work. The tool connection plate 3144 may engage mating features of the power head connection plate 3112 to provide positive mechanical and electrical locking of the opposing features. The connection plate 3144 may have a mating torque coupling 3152 to engage a power take off shaft 3130 of the power head. The coupling 3152 may also have an automatic speed selection feature 3154 that engages the speed selector mechanism 3138 to automatically match the output speed of the power head to the ideal input speed of the tool attachment. This selector mechanism 3134, 3138 is shown as a mechanical activated pushrod that may move the speed select lever 3132 of the power head to the chosen speed automatically, such as by a feature 3154 in the connection plate that positions the selector rod 3134 to the right length. This selector function may also be created electromechanically, such as with a sensor on the power head connection plate 3144 that identifies the tool attachment and makes the speed selection in the gearbox electromechanically via solenoids, servos, and the like. Each tool attachment 3102 may have a similar or different requirement for mechanical and electrical inputs to function appropriately and within each tool attachment 3102 may comprise specific mechanical gearing and mechanisms to actuate the end effecter 3150 according to its functional requirement. The tool attachment may have a transfer gearbox 3160 connected 3162 to the output shaft 3152, 3130 of the power head gear motor to provide the rotational torque of the gear shaft at the proper orientation and rpm required by the end effecter 3150. These gears may be a planetary cluster, worm and worm gear, bevel gears, internal gears, spur gears, right angle gears, and the like. There may be a mechanical mechanism 3164 connected to the output 3168 of the gearbox that provides the appropriate motion to the end effecter, such as a crankshaft and connecting rod or a bell crank to provide reciprocating motion, a geneva wheel to provide intermittent motion or any other mechanical modifier of the rotational motion that suits the requirement and is transmitted 3170 to the end effecter. The tool attachment may also require motions, sensing or other outputs that may be better provided by electronic components 3172 rather than mechanical components. Such electronic components may be interactively connected to the power head via internal wiring 3174 and may include solenoids or servo motors to effect on/off functions, limit switches to stop and start aspects of the mechanical system within the tool, sensors of many types for controlling the end effecter or responding to the environment, lasers and photo/optics of all kinds such as vision systems.

[0143] Referring now to FIG. 32, the power tool system 3200 is a tool system comprising a power base module 3204 of handle or control module, pole and power head facilitating attachment of a wide range of tool attachments 3202. Because the power tool system 3200 may require the user to deploy the tool at a considerable height, the overall weight of the extended tool and power head may be critical to ease of use. Thus, optimizing the distribution of heavy components such as motors, gearsets and other metal mechanisms may be important.

[0144] The power base component 3204 comprises a pole 3108 and a detachable power head 3110 which has a connection plate 3112 that permits the attachment of a wide range of tools 3202. In this embodiment, the power head 3110 may be configured to provide primary mechanical power to the tool attachment. The power head 3110 may be attached to the pole 3108 which conveys electrical power from an energy storage facility, such as a battery compartment, in the handle via conductors 3114, 3118 that are routed inside or outside the pole 3108. These electrical conductors are controlled by switches in the handle or control module and can carry either power 3114 to the motor(s) that is of relatively high voltage and current, or electrical signals 3118 that provide informational content to electronics mechanisms that control the tool attachments. The power head 3110 may comprise a high torque motor 3120 that provides power to the tool attachments 3202 via a power take off shaft 3130. The electrical signals may be passed through wires 3140 that bypass the motor to contacts 3142 on the mating connection plate 3112 that will engage mating contacts 216 on the connection plate 3208 of the tool attachment 3202.

[0145] The tool attachment 3202 comprises three parts that are the connection plate 3208, the tool body 3210 and the end effecter 3212 that accomplishes the work. The tool connection plate 3208 may engage mating features of the power head connection plate 3112 to provide positive mechanical and electrical locking of the opposing features. The connection plate may have a mating torque coupling 3214 that engage the power take off shaft 3130 of the power head. Because each tool 3202 may have unique requirements for torque and speed, it may be efficient to place all of the speed/torque gearing 3218 resident within the tool body 3210 itself and relieve the power head of the weight of gearing that may not be required by a light duty tool. Each tool attachment 3202 may have unique requirements for mechanical and electrical inputs to function appropriately and within the tool there may be required additional mechanical gearing and mechanisms to actuate the end effecter 3212 according to its functional requirement. The tool attachments may have a speed/torque control gearbox 3218 connected 3220 to the output shaft 3214, 3130 of the power head motor 3120 to provide the rotational torque of the gearshaft at the proper orientation and rpm required by the end effecter. These gears may be a planetary cluster, a worm and worm gear, bevel gears, internal gears, spur gears, right angle gears, and the like. There may also be a mechanical mechanism 3222 connected to the output 3224 of the gearbox that may provide the appropriate motion to the end effecter such as a crankshaft and connecting rod, a bell crank to provide reciprocating motion, a geneva wheel to provide intermittent motion or any other mechanical modifier of the rotational motion that suits the requirement and is transmitted 3228 to the end effecter.

[0146] The tool attachment may also require motions, sensing or other outputs that may be better provided by electronic components 3230 rather than mechanical components. Such electronic components may be interactively connected to the power head via internal wiring 3232 and may include solenoids or servo motors to effect on/off functions, limit switches to stop and start aspects of the mechanical system within the tool, sensors of many types for controlling the end effecter or responding to the environment, lasers and photo/optics of all kinds such as vision systems, and the like.

[0147] Referring now to FIG. 33, the power tool system 3300 may be a tool system comprising a base module 3304 of handle or control module, pole and power head facilitating the attachment of a wide range of tool attachments 3302. Because the power tool system may require the user to deploy the tool at a considerable height the overall weight of the extended tool and power head may be critical to ease of use. Thus, optimizing the distribution of heavy components such as motors, gearsets and other metal mechanisms may be important.

[0148] The base component may comprise a pole 3108 and a detachable power head 3110 which may comprise a connection plate 3112 that facilitates the attachment of a wide range of tools 3302. In this embodiment, the power head 3110 may be configured to provide electrical power and signals to the tool attachment. The power head 3110 may be attached to the pole 3108 which conveys electrical power from an energy storage facility, such as a battery compartment, in the handle or control module via conductors 3114, 3118 that are routed inside or outside the pole. These electrical conductors may be controlled by switches in the handle or control module and may carry either power 3114 to the motor(s) that may be of relatively high voltage and current, or electrical signals 3118 that may provide informational content to electronics mechanisms that control the tool attachments. The electrical signals may be passed to multiple contacts 3142 on the mating connection plate 3112 that may engage corresponding mating contacts 3314 on the connection plate 3308 of the tool attachment 3302.

[0149] The tool attachment 3302 may comprise three parts: the connection plate 3308, the tool body 3310 and the end effecter 3312 that accomplishes the work. The tool connection plate 3308 may engage mating features of the power head connection plate 3112 to provide positive mechanical and electrical locking of the opposing features. Because each tool may have unique requirements for torque and speed, it may be efficient to place the motor 3318 and all of the speed/torque gearing 3322 resident within the tool body 3310 itself and relieve the power head of the weight of gearing that may not be required by a light duty tool. The motor 3318 may transfer power to the gearbox via a coupling 3320 and the gearbox output shaft 3324 may pass the conditioned power to the tool mechanism 3328. These gears may be a planetary cluster, a worm and worm gear, bevel gears, internal gears, spur gears, right angle gears, and the like. Each tool attachment 3302 may have unique requirements for mechanical and electrical inputs to function appropriately and within the tool there may be required additional mechanical gearing and mechanisms to actuate the end effecter 3312 according to its functional requirement. There may also be a mechanical mechanism 3328 connected to the output 3324 of the gearbox that may provide the appropriate motion to the end effecter such as a crankshaft and connecting rod, a bell crank to provide reciprocating motion, a geneva wheel to provide intermittent motion or any other mechanical modifier of the rotational motion that suits the requirement and may be transmitted 3330 to the end effecter.

[0150] The tool attachment may also require motions, sensing or other outputs that may be better provided by electronic components 3332 rather than mechanical components. Such electronic components may be interactively connected to the power head via internal wiring 3334 and may include solenoids or servo motors to effect on/off functions, limit switches to stop and start aspects of the mechanical system within the tool, sensors of many types for controlling the end effecter or responding to the environment, lasers and photo/optics of all kinds such as vision systems, and the like.

[0151] Referring to FIG. 34, a power tool system 3400 may be a tool system comprising a base module 3408 of handle or control module, pole and power head facilitating the attachment of a wide range of tool attachments 3402, 3404. Because the power tool system may require the user to deploy the tool at a considerable height the overall weight of the extended tool and power head may be critical to ease of use. Thus, optimizing the distribution of heavy components such as motors, gearsets and other metal mechanisms may be important.

[0152] The power base component may be comprised of the pole 3108 and the detachable power head 3110 which may have a connection plate 3112 that facilitates the attachment of a wide range of tools 3302. In this embodiment, the power head 3110 may be configured to provide electrical power and signals to the tool attachment. The power head 3110 may be attached to the pole 3108 which conveys electrical power from an energy storage facility, such as a battery compartment, in the handle or control module via conductors 3114, 3118 that are routed inside or outside the pole. These electrical conductors may be controlled by switches in the handle or control module and may carry either power 3114 to the motor(s) that may be of relatively high voltage and current, or electrical signals 3118 that may provide informational content to electronics mechanisms that control the tool attachments. The electrical signals may be passed to multiple contacts 3142 on the mating connection plate 3112 that engage corresponding mating contacts 3314 on the connection plate 3308 of the tool attachment 3302.

[0153] A wide range of tool attachments may be available for the power tool system. Some tools may be relatively complex in function 3402 and other tools may be simple 3404. Both complex and simple tool attachments may comprise at least three parts: the connection plate (3410 and 3440), the tool body (3412 and 3442) and the end effecter (3414 and 3444) that accomplishes the work. The tool connection plate (3410 and 3440) may engage mating features of the power head connection plate 3112 to provide positive mechanical and electrical locking of the opposing features. Because each tool 3402, 3404 may have unique requirements for the electromechanical mechanism, it may be efficient to place that mechanism resident within the tool body (3412 and 3442) itself and relieve the power head of the weight of gearing that may not be required by a light duty tool (3404).

[0154] In the embodiment of a more complex tool 3402, the motor 3420 may transfer power to the gearbox via a coupling 3422 and the gearbox output shaft 3428 may pass the conditioned power to the tool mechanism 3328. These gears may be a planetary cluster, a worm and worm gear, bevel gears, internal gears, spur gears, right angle gears or others. Each tool attachment may have a unique requirement for mechanical and electrical inputs to function appropriately and within the tool there may be required additional mechanical gearing and mechanisms to actuate the end effecter 3414 according to its functional requirement. There may also be a mechanical mechanism 3430 connected to the output 3428 of the gearbox that may provide the appropriate motion to the end effecter such as a crankshaft and connecting rod or a bell crank to provide reciprocating motion, a geneva wheel to provide intermittent motion or any other mechanical modifier of the rotational motion that suits the requirement and is transmitted 3432 to the end effecter.

[0155] The tool attachment may also require motions, sensing or other outputs that may be better provided by electronic components 3434 rather than mechanical components. Such electronic components may be interactively connected to the power head via internal wiring 3438 and include solenoids or servo motors to effect on/off functions, limit switches to stop and start aspects of the mechanical system within the tool, sensors of many types for controlling the end effecter or responding to the environment, lasers and photo/optics of all kinds such as vision systems, and the like.

[0156] The weight and cost savings for the base system of the power tool that may be obtained by placing all of the power and drivetrain in the tool attachment can be appreciated when a simple tool 3404 is analyzed. A tool such as the aerosol spraying attachment for the power tool system enables the remote activation of an aerosol spray can, such as insecticide, paint, lubricant, and the like, but requires only a solenoid and simple linkage for activation. The elecromechanical element 3450 may be simply connected 3452 to the end effecter and requires no other elements for a fully functional device.

[0157] Referring now to FIG. 35, the power tool system 3500 may be a tool system comprising a base module 3510 of handle or control module, pole and power head and a wide range of tool attachments 3502, 3504. Because the power tool system may require the user to deploy the tool at a considerable height the overall weight of the extended tool and power head may be critical to ease of use. Thus, optimizing the distribution of heavy components such as motors, gearsets and other metal mechanisms may be important. In many instances there are a range of tools that have similar power requirements, such as a tree saw, hedge trimmer and sickle bar trimmer, may all require reciprocating motion and similar rpm and torque inputs and an efficient approach may be to create a platform of product around a platform power module 3508 so that several attachments can operate off a standard gearmotor/mechanism.

[0158] The base component may comprise a pole 3108 and the detachable power head 3110 which may have a connection plate 3112 that permits the attachment of the platform power module 3508. In this embodiment, the power head 3110 may be configured to provide electrical power and signals to the platform power module 3508 attachment. The power head 3110 may be attached to the pole 3108 which conveys electrical power from the energy storage facility, such as a battery compartment, in the handle via conductors 3114, 3118 that are routed inside the pole. These electrical conductors may be controlled by switches in the handle and can carry either power 3114 to the motor(s) that is of relatively high voltage and current, or electrical signals 3118 that provide informational content to electronics mechanisms that control the tool attachments. The electrical signals may be passed to multiple contacts 3142 on the mating connection plate 3112 that may engage corresponding mating contacts 3518 on the connection plate 3512 of the platform power module 3508.

[0159] Each platform power module 3508 may support a range of similar tool attachments. The adaptive nature of the platform power module 3508 may allow a family of tool attachments to be very simple. In the platform power module 3508, the motor 3520 may transfer power to the gearbox via a coupling 3522 and the gearbox output shaft 3528 may pass the conditioned power to the platform power module 3508 mechanism drive 3524. The gearbox may be a planetary cluster, a worm and worm gear, bevel gears, internal gears, spur gears, right angle gears or others. Each tool family may have unique requirements for mechanical and electrical inputs to function appropriately and within the tool there may be required additional mechanical gearing and mechanisms to actuate the end effecter 3544, 3570 according to its functional requirement. The platform power module 3508 may have a mechanical mechanism 3524 connected to the output 3522 of the gearbox that may provide the appropriate motion to the end effecter such as a crankshaft and connecting rod or a bell crank to provide reciprocating motion, a geneva wheel to provide intermittent motion or any other mechanical modifier of the rotational motion that suits the requirement and is transmitted 3528 to the connection plate 3516 that will adapt the tool. The tool attachments may also require motions, sensing or other outputs that may better be provided by electronic components rather than mechanical components. Such electronic components may be interactively connected to the platform power module 3508 via internal wiring 3538 that pass the power and signals to contacts 3534 on the connection plate 3516.

[0160] The range of simple tool attachments for a platform family may comprise three parts: the connection plate (3540 and 3564), the tool body (3542 and 3568) and the end effecter (3544 and 3570) that accomplishes the work. The tool connection plate (3540 and 3564) may engage mating features of the platform power module 3508 connection plate 3516 to provide positive mechanical and electrical locking of the opposing features. The electrical functional elements may include solenoids or servo motors to effect on/off functions, limit switches to stop and start aspects of the mechanical system within the tool, sensors of many types for controlling the end effecter or responding to the environment, lasers and photo/optics of all kinds such as vision systems, and the like.

[0161] The weight and cost savings for the base system of the power tool and for the range of family tool modules that can be obtained by placing all of the power and drivetrain in the platform power module can be appreciated when the family platform toolset is analyzed. The range of tools that may adapt to the similar outputs of the platform power module require minimal differentiation in the mechanical linkages. The end effecter 3544, 3570 may be connected via the pass-through connection 3560, 3584 of the connector plate 3540, 3564 interface and the connections of the connecter plate for mechanical power 3548, 3572 and electric signal 3552, 3578 may be completed requiring no other elements for a fully functional device.

[0162] Referring to FIG. 8, an embodiment of a gutter cleaning system 802 is shown in use. The system 802 may comprise a guide pole 804, impellers 808, impeller chutes 810, and support/guide wheels 812. The system 802 may be configured to allow a user to deploy the system 802 into a gutter with the use of the guide pole 804. In some embodiments, the guide pole 804 may be a telescoping pole. In some embodiments, the user may lift the gutter-cleaning system to the gutter from below, place it in the gutter, and initiate operation of the gutter-cleaning system either before or after placing the system within the gutter. The user may move the gutter-cleaning system along the gutter floor, optionally with the aid of a support guide/wheel. In other embodiments, a user may lower a gutter-cleaning system into a gutter from above, such as from a window. The impellers 808 may dislodge and evict gutter debris from the gutter. The impeller chutes 810 may direct the high velocity gutter debris over the outer edge of the gutter. The support/guide wheels 812 may use the gutter edge to ease movement of the system through the gutter trough.

[0163] Referring to FIG. 9, an embodiment of a gutter cleaning system 900 is depicted. The gutter cleaning system 900 may comprise a power base 902, impellers 904 on both ends of the gutter-cleaning device 924, a chute housing 908 for each impeller 904, support/guide wheels 910, fasteners 914, a locking pivot 912, a handle control 918, a grip area 920, a rechargeable battery 922, and the like. The system may be configured to allow a user to deploy the system into a gutter with the use of the power base 902. In some embodiments, the power base 902 may comprise a telescoping pole.

[0164] Referring to FIG. 10, an embodiment of a gutter cleaning system 1002 is shown. The system 1002 may comprise a guide pole 1004, impellers 1008, impeller chutes 1010, and support/guide wheels 1012. The system 1002 may be configured to allow a user to deploy the system 1002 into a gutter with the use of the guide pole 1004. In some embodiments, the guide pole 1004 may be a telescoping pole. The impellers 1008 dislodge and evict gutter debris from the gutter. The impeller chutes 1010 direct the high velocity gutter debris over the outer edge of the gutter. The support/guide wheels 1012 use the gutter edge to ease movement of the system through the gutter trough.

[0165] Referring to FIG. 11A, a counter-rotating brush gutter cleaner 1100 may capture gutter debris in the counter-rotating brushes 1104 and move the captured debris against the surface of the gutter into the cleaner 1100. Eventually, the debris may break free of the cleaner 1100 and get discharged from the chute 1102 disposed between the brushes 1104 at high enough velocity so it clears the outside wall of the gutter and falls to the ground or is otherwise ejected, captured, and the like. The cleaner 1100 may attach to a power base 160 at an attachment point 1108.

[0166] Referring to FIG. 11B, a cutaway view of the gear mechanism for the counter-rotating brushes 1104 is shown. A single gear 1110 or multiple gears 1110 may engage a gear 1110 disposed on a counter-rotating brush 1104 and cause the brush 1104 to rotate about a central axis. The primary gear driving the assembly may be driven by a power take-off coupling of a power base. In an alternative embodiment, the brushes 1104 may be directly rotated along a driven axle. The counter-rotating brushes 1104 may be flexible full-width paddles, full circumference flexible bristle cylindrical brushes, spiral flexible bristle brushes, spiral flexible straight or hooked-end wire brushes, flexible alternating brush paddles, flexible bucket paddles, alternating blade flexible paddles, and the like.

[0167] Referring to FIG. 12, the gutter-cleaning device 1200 may comprise an impeller 1202 on both ends of the device, a chute 1204 housing for each impeller, a top fastener 1208, an impeller drive shaft 1210, an impeller drive motor 1212, an impeller drive transmission 1214, support/guide wheels 1218, and the like. The impeller 1202 may be mounted to the impeller drive shaft 1210. The impeller drive shaft 1210 may be coupled to the impeller transmission 1214 and configured to extend out each end of the impeller transmission 1214 to connect to each impeller 1202 at each end of the gutter-cleaning device 1200. The impeller drive motor 1212 may be mechanically coupled to the impeller transmission 1214 such that the rotational output of the impeller drive motor 1212 is a rotational input to the impeller transmission 1214. In some embodiments of the gutter-cleaning device 1200, the device may comprise an impeller drive motor 1212 for each impeller 1202. In some embodiments, the impeller drive motor 1212 may be mounted within each impeller 1202. The combination of the impeller drive motor 1212 and impeller drive transmission 1214 may be configured and disposed to drive the impeller 1202 with the required rotational speed and torque. In some embodiments, the impeller drive motor 1212 may comprise a gasoline- or biofuel-powered internal combustion engine, a solar-powered engine, an electric motor, and the like. In embodiments, the gutter cleaning device 1200 may further comprise an energy storage facility disposed within the housing. In this embodiment, the gutter-cleaning device 1200 may not need power supplied to it exogenously. In embodiments, the gutter-cleaning device 1200 may not comprise an energy storage facility or other means to obtain power and must therefore be powered exogenously. In this embodiment, the gutter-cleaning device 1200 may be connected to a power base, as described herein, to obtain power. The energy storage facility may be housed within the power base or placement facility and electrically connected to the impeller drive motor 1212.

[0168] Referring to FIG. 13, a multi-functional power tool system may comprise a power base 1302 with a head configured to attach interchangeable functional modules. In an embodiment, a single power base 1302 may be able to connect with a variety of different functional modules to provide power and/or control to the attached modules. For example, a user may have a need to perform various outdoor cleaning tasks, such as gutter cleaning and power window washing. The user may mount a gutter-cleaning device with counter-rotating brushes to a power base, lift the device into place in the gutter, and then guide the device along the gutter floor, optionally with the aid of a support guide/wheel, to remove debris in the gutter. Then, the user may dismount the gutter-cleaning device and attach the power window washing module to the power base. The power base may facilitate many such combinations of accomplishments with various functional modules. The multi-functional power tool system may require less storage, such as at an end-use location, a retail location, a warehouse, a distributor, and the like, for the single power base and multiple attachments than for dedicated equipment corresponding to each of the attachments. Manufacturing and distribution may be simplified since the power base may be an invariable, standard component of the system utilized with many different functional modules. The multi-functional power tool system may support future expansion by simply obtaining a functional module that is compatible with the power base. The multi-functional power tool system may be easy to repair and maintain since a single energy storage facility needs to be re-energized, a single component may comprise the majority of the powertrain, the functional modules may be easy to repair since they may lack a majority of the powertrain, and the like.

[0169] In an embodiment, the functional modules may attach to the power base 1302 at a mounting plate. The functional modules may be cleaning modules 1304, gutter cleaning modules 1308, holding and fastening modules 1310, finishing and painting modules 1312, inspection modules 1314, landscape/garden modules 1318, and the like. In an embodiment, the functional module may comprise some or all of the necessary elements to receive power from the power base 1302, optionally through a power head, and use it to drive operation of the module. In an embodiment, the functional module may comprise some or all of the necessary elements to receive control signals from the power base 1302 and to act on the received signals. In any event, any of the functional elements of the functional module may be disposed within the functional module or the power base 1302. The power base 1302 may comprise any elements necessary to provide power, control, motive force, and the like to a functional module.

[0170] In an embodiment, cleaning modules 1304 may be used with the power base 1302 to provide a cleaning power tool system. The cleaning modules 1304 may be a microvacuum module 1320, various vacuum heads 1322, such as a brush, a crevice nozzle, and the like, a rotating feather duster 1324, a turbine dusting blower 1328, a power window cleaner with fluid dispensing head powered roller with squeegee 1330, a sweeper, a scrub brush, a liquid pump, a degreaser pump, a shoe shiner, and the like. The functions and settings for each functional module may be modified by a user's manual adjustment, a control facility 168, and the like. For example, the rate of the liquid pump, the force of the dusting blower, the speed of the scrub brush, and the like may all be adjusted.

[0171] Referring now to FIG. 51, the window washing tool attachment 5100 to the power tool system may provide the user the ability to wash windows on upper stories or in high interior spaces which may be advantageous as it will keep the user from a dangerous position on the top of a ladder. The window washing attachment 5102 may provide a complete system for cleaning glass and may comprise three basic elements: a rotating scrubbing brush 5104, a washing fluid dispensing system 5112 and a squeegee 5108. The window washing tool attachment may attach to the power head 5122 of the power tool system. The power head may have a rotating joint 5124 that allows the user to adjust the angle of the window washing tool to the window plane. The window washing tool attachment may attach to the power head 5122 of the power tool system by a connection plate 5120 that may provide registration features to align mechanical components and resist torque couples and provides slip-free engagement of the power output shaft to the input shaft of the window washing tool assembly. The rotational power provided by the power head may be transferred via a gear train in the body 5114 of the tool to turn the cylindrical scrubbing brush 5104 with the geartrain connecting to the horizontal rotational axis 5110 of the brush. Washing fluid 5112 may be dispensed onto the window via distribution tubes and spray heads 5118 by an electrical pump internal to the body of the tool 5114 that may be triggered by electrical connection, transferred through the connection plate when the user switches power to the pump from a control in the handle of the power tool system. After scrubbing the window, the user may squeegee the glass clean with the built-in squeegee 5108 that may be activated to the forefront use condition by an electrical input from the handle.

[0172] Referring to FIG. 52, the window washing tool attachment 5200 to the power tool system may provide the user the ability to wash windows on upper stories or in high interior spaces which may be advantageous as it will keep the user from a dangerous position on the top of a ladder. The window washing attachment may provide a complete system for cleaning glass and may comprise three basic elements: the rotating scrubbing brush 5202, the washing fluid dispensing system 5234 and the squeegee 5204. The window washing tool attachment may attach to the power head of the power tool system by a connection plate 5208 that provides registration features 5212 to align mechanical components and resist torque couples and provides slip-free engagement of the power output shaft to the input shaft 5210 of the window washing tool assembly. Electrical contacts 5214 may transfer electrical current switched by the user from the handle controls to energize electromechancial components in the window washing tool. The rotational power provided by the power head may be transferred via the input shaft 5218 to a right angle input bevel gear 5220 that meshes with an identical output bevel gear 5222 at right angles to the input gear that drives a horizontal transfer shaft 5224. Either of the bevel gears may be of a different pitch diameter to provide a gear reduction or increase as required by the output rotational speed desired for the cylindrical scrubbing brush. One or both ends of the transfer shaft 5224 may have timing gears 5228 affixed that transfer the power to another timing gear 5232 affixed to the end of the cylindrical scrubbing brush 5202 central shaft. This connection may also be achieved by other gearing alternatives such as two ninety degree bevel gear connections or a flexible shaft drive. Cleaning fluid 5238 may be supplied to the window surface via a fluid reservoir 5234 and pump 5242 system. A fluid reservoir 5234 which contains a usable volume of cleaning fluid 5238 and may be refillable by a fluid channel with a fluid-proof cap 5240 may be dispensed by an electrical pump 5242 to the window surface. The electrical pump may run and pump fluid onto the window surface when the user triggers a switch on the power tool system handle and electricity is conducted through the conductor contacts 5213 of the window cleaning tool attachment via electrical wires 5250 to the electrical connections 5248 to the pump 5242. The pump may pull washing fluid 5238 from the reservoir 5234 via a conveyance tube 5244 and pressurizes the fluid as it pumps it into the distribution tube 5252 by which it is conveyed to the spray nozzles 5254 wherein it is deposited as a fine mist onto the window pane. Alternatively, the fluid may be dispensed onto the brush 5202 itself wherein it is used to scrub dirt from the window pane. After scrubbing the window, the user squeegees the glass clean with the built-in squeegee 5204 that may be mounted on an armature 5258 with a pivot on or near the rotational axis of the cylindrical brush 5202 activated to the forefront use condition by the activation of an electrical solenoid 5260, servo or other electromechanical device that may provide translation of and appropriate force and direction so that the squeegee blade 5204 moves forward to a foremost contact point that permits the movement of the window washing assembly to squeegee the fluid and dirt from the window surface. The solenoid or other device may be activated when the user triggers a switch on the power tool system handle and electricity is conducted through the conductor contacts 5213 of the window cleaning tool attachment via electrical wires 5262 to the electrical connections to the solenoid 5260 or other electromechanical device and the squeegee armature moves forward so that the squeegee may be in the usable position.

[0173] In an embodiment, gutter cleaning modules 1308 may be used with the power base 1302 to provide a gutter cleaning power tool system. The gutter cleaning modules 1308 may be a gutter-cleaning device with impellers, as previously described herein, a counter-rotating brush gutter cleaner 1332, a downspout cleaning brush 1334, a vibratory (ultrasonic, mechanical, etc.) micro-needle for ice removal 1338, any of the gutter-cleaning devices in FIGS. 9-12, and the like.

[0181] Referring now to FIG. 41, the Painting Roller tool attachment 4100 to the power tool system may provide the user the ability to apply paint with a standard roller at a height, such as up to twenty feet, which may be advantageous as it will keep someone from a dangerous position on the top of a ladder. The Painting Roller attachment may provide a complete system for applying paint from a paint can and may comprise three basic modules: the pump assembly 4108, hose 4118 and painting roller head 4132 that attaches to the power head of the power tool system. The Painting Roller tool may utilize a pump assembly 4108 that engages the lid attachment recess of a paint can 4102. The pump assembly 4108 utilizes a siphon tube 4110 that extends below the lid attachment to take paint 4104 from the lowest point of the paint can so it will work until the paint is exhausted. The pump 4112 itself may be electric or operate from a battery or rechargeable battery 4114, or any power means. The pump 4112 may utilize the battery of many standard rechargeable tools. The pump 4112 is self-priming and will push the paint up the paint delivery tube 4118 that coils on or beside the pole system of the power tool system. The Painting Roller tool attachment may connect to the power head of the power tool system by a connection plate 4122 that registers and couples the power output shaft of the power head to the input drive shaft 4124 of the Painting Roller tool attachment. The body 4120 of the Painting Roller tool attachment may have a connection for the paint delivery tube 4118 and a distribution manifold 4128 that distributes paint evenly along the length of the roller 4130. The removable roller 4130 may have a paint spray shield 4132 that protects the user and environment from splatter as the paint 4104 is applied.

[0182] Referring now to FIG. 42, the Painting Roller tool utilizes a pump assembly 4202 that engages precisely into the lid attachment recess of a standard paint can 4102. The pump assembly 4202 may utilize a siphon tube 4204 that extends below the lid attachment to take paint 4104 from the lowest point of the paint can so it will work until the paint is exhausted. The pump 4208 itself may be electric and operate from standard 110 VAC line current with a standard plug and electric cable. The pump 4208 may be self-priming and will push the paint up the paint delivery tube 4212 that coils on or beside the pole system of the power tool system. The Painting Roller tool attachment may connect to the power head of the power tool system by a connection plate 4122 that registers and couples the power output shaft of the power head to the input drive shaft 4124 of the Painting Roller tool attachment.

Generally, the aerosol spray can actuator 1380 may be adapted to receive any and all input power, such as and without limitation electrical power, and to convert the input power into pressure that is applied to the pressure valve of the aerosol spray can. Embodiments of the aerosol spray can actuator 1380 may include an adjustable friction clutch for converting the input torque into pressure, a solenoid for converting electrical input power into pressure, or any and all other devices for converting the input power into the pressure. In any case, the pressure may actuate the pressure valve of the aerosol spray can, causing the aerosol spray can to discharge. It will be understood that various embodiments of the aerosol spray can actuator 1380 are possible.

[0187] Referring now to FIG. 36, the Aerosol Spray tool attachment 3600 to the power tool system provides the user the ability to activate spray cans at a distance, such as up to twenty feet, which may be advantageous, such as if one is trying to spray insecticide on a wasp nest and is not forced to do it in close proximity on the top of a ladder. The tool may also be useful for spraying paint cans, lubricants, insecticides, herbicides, and many other products packaged in aerosol containers where proximity may be hazardous or noxious. The power stick Aerosol Spray attachment may be a compact product 3602 that attaches to an aerosol can 3604 and facilitates remote actuation of the spray nozzle 3608. The Aerosol Spray attachment connects the aerosol can by means of a band clamp 3610 or any other clamping method that will firmly grip the diameter of the can such as a C-clamp, clamshell clamp, closed ring, sticky foam or viscoelastic polymer band, magnetic band, or the like, holding the aerosol can firmly to the body 3622 of the device. The Aerosol Spray tool attachment may connect to the power head of the power stick by a connection plate 3612 that registers and couples the power output shaft of the power head to the input drive shaft 3614 of the Aerosol Spray tool attachment. Activation of the aerosol can spray nozzle may be accomplished by depressing the nozzle plate 3618 against the aerosol can nozzle 3608 as it hinges from a connection point 3620 on the body 3622 of the device. The activation force may be provided by several methods including a friction cam 3624 that is activated by the rotational force applied by the input drive shaft 3614, driving the nozzle plate downward when torque is applied by activation of the power head motor by the user and depressing the aerosol nozzle thus dispensing the spray can contents.

[0188] Referring now to FIG. 37, the power stick Aerosol Spray attachment is a compact product 3700 that is shown in this engineering diagram in three views, the front view 3702, the side view 3708 and the top view 3704. The Aerosol Spray tool attachment attaches to an aerosol can 3710 and facilitates remote actuation of the spray nozzle 3712. The Aerosol Spray attachment connects the aerosol can by means of a band clamp 3714 or any other clamping method that will firmly grip the diameter of the can such as a C-clamp, clamshell clamp, closed ring, sticky foam or viscoelastic polymer band, magnetic band, or many others, holding the aerosol can firmly to the body 3718 of the device. The Aerosol Spray tool attachment connects to the power head of the power stick by a connection plate 3720 that registers and couples the power output shaft of the power head to the input drive shaft 3724 of the Aerosol Spray tool attachment. Activation of the aerosol can spray nozzle 3712 is accomplished by depressing the nozzle plate 3728 against the aerosol can nozzle 3712 as it hinges from a connection point 3730 on the body 3718 of the device. The nozzle plate is held in the open position by a spring, illustrated here as a torsion spring 3732 but which can be of any sort including mechanical, pneumatic, hydraulic, magnetic or other. The activation force can be provided by many mechanical, chemical and electrical methods including a friction cam 3734 that is activated by the rotational force applied by the input drive shaft 3724. The friction cam 3734 may be adjusted to provide enough torque to drive the cam downward onto the nozzle plate 3728, that force being enough to depress the aerosol can spray nozzle but when that nozzle reaches the stop point, the input shaft will rotate freely inside the cam with the limiting torque being adjustable by a friction collar 3738 and a friction collar adjusting screw 3740 so that the correct balance is obtained. The nozzle plate 3728 is driven downward 3742 by the torque of the friction cam 3734 generated by the power head motor when the user switches power to the power head and depresses the aerosol nozzle 3712 thus dispensing the medium.

[0189] Referring now to FIG. 38, the power stick Aerosol Spray attachment is a compact product 3800 that is shown in this engineering diagram in three views, the front view 3802, the side view 3808 and the top view 3804. The Aerosol Spray tool attachment attaches to an aerosol can 3710 and facilitates remote actuation of the spray nozzle 3712. The Aerosol Spray attachment connects the aerosol can by means of a band clamp 3810 or any other clamping method that will firmly grip the diameter of the can such as a C-clamp, clamshell clamp, closed ring, sticky foam or viscoelastic polymer band, magnetic band, or many others, holding the aerosol can firmly to the body 3812 of the device. The Aerosol Spray tool attachment connects to the power head of the power stick by a connection plate 3814 that registers and couples the electrical contact of the power head to the electrical contact 3818 of the Aerosol Spray tool attachment. Activation of the aerosol can spray nozzle 3712 is accomplished by depressing the nozzle plate 3822 against the aerosol can nozzle 3712 as it hinges from a connection point 3824 on the body 3812 of the device. The nozzle plate may be held in the open position by a spring, illustrated here as a torsion spring 3828 but which can be of any sort including mechanical, pneumatic, hydraulic, magnetic or other. The activation force may be provided by many mechanical, chemical and electrical methods including a short-stroke power out solenoid 3830 that is activated by electrical current applied by the power system of the power stick and conducted through the electrical contact 3818 to the solenoid 3830. The stroke of the solenoid rod 3832 on the back beam 3834 of the nozzle plate may be enough to drive the front beam 3838 of the nozzle plate 3822 downward onto the aerosol can spray nozzle 3712, that force being enough to depress the aerosol can spray nozzle but when that nozzle reaches the stop point, the stroke of the solenoid is at its end and residual energy is not enough to overwhelm the mechanical system. The nozzle plate 3822 is driven downward 3838 when the solenoid is energized by the electrical current flowing through the power head when the user switches the power ON and the aerosol nozzle 3712 thus dispenses the spray can contents.

[0190] A user may deploy the multi-functional power tool system by mounting a device/functional module at a head of a power base. The power base may comprise a telescoping pole, a static pole, a control module, a handle, and the like. In embodiments, in order to operate the functional module at or near a desired location, a user may lift the functional module at an end of the power base to a desired location and initiate control of the module either before or after placing the module near the desired location. For example, referring to FIG. 14, downspout cleaning tools 1400 may be used with the power base 1302 to clear a downspout. In an embodiment, the downspout cleaning tool 1400 may be an auger brush 1334. The auger brush 1334 may be placed in a downspout and actuated to rotate and clean the downspout with the action of the rotating bristles. In an embodiment, the downspout cleaning tool 1400 may be an auger tool with impellers 1402. The impellers may be disposed along the auger for facilitating removal of debris from a gutter downspout. In an embodiment, the downspout cleaning tool 1400 may be an auger tool with teeth 1404 for chopping material in a downspout, such as large debris or ice. In any case, an auger element of the downspout cleaning tools 1400 may include a gear transfer coupling that provides gravity plumb orientation for the auger element. The gravity plumb orientation may enable the auger element to find its way into an opening of a downspout. In another example, referring to FIGS. 15A & 15B, a pruning shear 1378 may be used with a power base 1302 to prune foliage. In an embodiment, the drive from the power base may engage a worm screw 1502 to drive a worm gear 1504. The worm gear 1504 may connect to the pivoting pruning blade 1508 via a connecting rod 1510 to create a reciprocating motion of the pruning blade 1508 against the fixed blade 1512 and shear items disposed between the pruning blade 1508 and the fixed blade 1512. In embodiments, there may be a friction clutch 1514 between the worm gear 1504 and the plate to which the connecting rod 1510 attaches so that if an attempt is made to cut an oversized object, such as an oversized branch, the friction disc would spin so as to not burn out the motor or overload the geartrain.

[0191] Referring to FIGS. 16A and B through 18, embodiments of a reciprocating tree saw attachment for use with the power base are depicted with a gripping guard. The gripping guard may be spring loaded.

[0192] Referring now to FIG. 44, the tree saw tool attachment 4400 to the power tool system may provide the user the ability to cut tree limbs at a distance, such as up to twenty feet, which may be advantageous as it may permit a wide range of pruning activities without the hazard of climbing a ladder to perform the cutting task. The power tool system tree saw tool attachment connects to the power head 4404 of the power tool system 4402 by a connection plate 4408 that registers and couples the power output shaft of the power head to the input drive shaft of the tree saw tool attachment. The body 4410 of the tree saw tool attachment may comprise a mechanism that converts the rotational input from the power head and converts it to reciprocating motion that drives the saw blade 4412. The saw blade 4412 may be protected by a hinged and spring-loaded 4418 blade guard 4414 that opens when forced against the tree branch 4420 and holds the blade in alignment as the cutting takes place, and may also relieve the weight of the power tool system on the user's arms during the duration of the cut.

[0193] Referring now to FIG. 45, the tree saw tool attachment 4500 to the power tool system may provide the user the ability to cut tree limbs at a distance of up to twenty feet using the extensible pole system. The power tool system tree saw tool attachment connects to the power head of the power tool system by a connection plate 4502 that registers and couples the power output shaft of the power head to the input drive shaft 4504 of the tree saw tool attachment. The body 4510 of the tree saw tool attachment comprises a right angle drive gearbox 4508 and a mechanism that converts the rotational input from the power head and converts it to reciprocating motion that drives the releasable chuck 4514 that holds the saw blade 4518. The saw blade 4518 may be protected by a hinged and spring-loaded blade guard 4520 that opens when forced against the tree branch and holds the blade in alignment as the cutting takes place, and may also relieve the weight of the power tool system on the users arms during the duration of the cut.

[0194] Referring now to FIG. 46, the tree saw tool attachment 4600 to the power tool system may provide the user the ability to cut tree limbs at a distance, such as up to twenty feet, using the extensible pole system. The body 4610 of the tree saw tool attachment contains a mechanism that converts the rotational input from the power head to reciprocating motion that drives a piston arm 4608 and at the end there is a releasable chuck 4604 that holds the saw blade 4602. The saw blade 4602 may be protected by a hinged and spring-loaded blade guard 4612 that opens when forced against the tree branch and holds the blade in alignment as the cutting takes place, and may also relieve the weight of the power tool system on the user's arms during the duration of the cut.

[0195] Referring to FIG. 47, the tree saw tool attachment 4700 to the power tool system may provide the user the ability to cut tree limbs at a distance, such as up to twenty feet, using the extensible pole system. The power tool system tree saw tool attachment may be a compact product 4700 that is shown in this engineering diagram in two views, the top view 4702 and the side view 4704. The power tool system tree saw tool attachment may connect to the power head of the power tool system by a connection plate 4708 that is registered 4714 to resolve the torque load and couples the power output shaft of the power head to the input drive shaft 4710 of the tree saw tool attachment. The input shaft may be connected to a right angle bevel gear 4712 that drives a similar mating bevel gear 4718 at ninety degrees on a vertical output shaft 4720. Affixed to the top of the output shaft may be a flywheel 4722 that has a crankpin attached at the outer perimeter 4724. There may be a connecting rod 4730 that pivots upon the crankpin that in turn is connected by another pivot connection to the end of the piston shaft 4732. As the flywheel 4722 rotates the connecting rod's 4730 pivot-attached end at the crankpin 4724 describes a circle, the diameter of which is the stroke of the piston rod 4732 pivot-attached at the other end. For every rotation of the flywheel, the piston rod 4732 may make one forward and one backward stroke. At the far end of the piston is a chuck 4734 that captures the end of the saw blade 4738. On either side of the saw blade may be a blade guard element 4740 both of which are combined together on a hinge pin to create a rigid element and that may be spring-loaded upward to the closed position to protect against impingement on the blade. In the closed position the front of the blade guard may have a mouth-like opening 4740 that when pushed against a cylindrical object 4748 such as a tree branch will force open the blade guard 4742 admitting the branch 4748 and capturing it between the guard and the saw blade thus ensuring a consistent cutting motion and contact between blade and tree.

[0196] Referring now to FIG. 48, the tree saw tool attachment 4800 to the power tool system may provide the user the ability to cut tree limbs at a great distance using the extensible pole system. The power tool system tree saw tool attachment is shown in this engineering diagram in two views, the top view 4802 and the side view 4804.

On either side of the saw blade may be a blade guard 4810 both of which are combined together on a hinge pin to create a rigid element and that may be spring-loaded 4812 downward to the closed position to protect against impingement on the blade. In the closed position the blade guard 4810 may form a hook that can be hooked over the tree branch 4748 thus supporting the weight of the power tool system head assembly at the end of the pole. As cutting commences, the weight of the head may follow the cut into the branch 4748 and the spring-loaded blade guard 4814 may move upward out of the way while the cut progresses although still supporting some of the weight of the head. When the cut is complete and the branch 4748 falls away, the blade guard 4810 may snap back into place to protect the saw blade 4808.

[0241] Referring to FIG. 53, the light bulb changing tool attachment 5300 to the power tool system 5302 may provide the user the ability to remove and replace a light bulb 5320 at an extended reach while it minimizes the danger by keeping the user off a ladder. The light bulb changing tool attachment may connect to the power head 5314 of the power tool system 5312 by a connection plate that registers and couples the power output shaft of the power head to the input drive shaft of the light bulb changing tool attachment. The body 5318 of the light bulb changing tool attachment contains a mechanism that creates a very low speed rotation of the bulb in either direction while limiting the torque that can be applied so that the danger of breaking a bulb 5320 from over-tightening is eliminated. The end effecter 5304 which grips the light bulb may be a multi-lobed gripper 5324 that has conformable lobes 5328 to accommodate the range of light bulb shapes. It may attach to the light bulb changing tool attachment with a hub 5322 that incorporates a hex shaft that couples to the hex chuck of the light bulb changing tool attachment. For applications that require replacement of standard globe incandescent light bulbs 5308 the lobes of the gripper 5332 may be conformed to the spherical shape of the lower portion of the light bulb 5334. The hub 5330 of the gripper may attach to the light bulb changing tool attachment with a quick release mechanism. When the application 5310 requires replacement of a flood light type bulb 5342 the lobes of the gripper 5340 may flatten to accept the flattened face of the flood light bulb. The hub of the gripper may have a hex shaft 5338 that may engage the quick release hex chuck of the light bulb changing tool attachment.

[0242] Referring now to FIG. 54, the light bulb changing tool attachment 5400 to the power tool system may provide the user the ability to remove and replace a light bulb at an extended reach while it minimizes the danger by keeping the user off a ladder. The power tool system light bulb changing tool attachment may be a compact product that is shown in this engineering diagram in three views, the top view 5402, the side view 5404 and the end view 5408. There is also an exploded side section view 5432 that shows the elements of the torque limiting clutch. The light bulb changing tool attachment connects to the power head of the power tool system by a connection plate 5414 that registers and couples the power output shaft of the power head to the input drive shaft 5418 of the light bulb changing tool attachment. The body 5410 of the light bulb changing tool attachment comprises a mechanism that creates a very low speed rotation of the bulb in either direction while limiting the torque that can be applied so that the danger of breaking a bulb from over-tightening is eliminated. The end effecter which grips the light bulb may be a multi-lobed gripper that has conformable lobes to accommodate the range of light bulb shapes. It may attach to the light bulb changing tool attachment with a hub that incorporates a hex shaft that couples to the quick-release hex chuck 5412 of the light bulb changing tool attachment that utilizes a ball-detent locking mechanism. The input shaft of the light bulb changing tool may be attached to a worm 5420 that engages a worm gear 5422 on a transverse vertical shaft that rotates at a greatly reduced rpm and in turn is attached to a right angle bevel gear 5424. Mated with this right angle bevel gear 5424 is an identical bevel gear 5428 attached to a shaft at ninety degrees that is the output shaft 5430, driving the torque limiting slip-clutch 5432. The output shaft 5430 connects to the driving bevel gear 5428 and to the slip-clutch cage 5438 as a single rotating unit. Internal to the slip-clutch cage 5438 may be the split friction sleeve 5440 that creates an adjustable friction connection between the slip-clutch cage 5438 and the internal drive sleeve 5442. This adjustable friction may be applied in a number of ways but here is effected by set screws 5434 that apply inward pressure on the split sleeve 5440. The drive sleeve 5442 may be affixed to the output hex shaft 5444 of the quick-release hex chuck 5412 of the light bulb changing tool attachment by a hex bore in the drive sleeve that resolves the torque load transferred to the drive sleeve. The quick-release hex chuck 5412 of the light bulb changing tool attachment may be retained by a retainer washer 5448, keeping the assembly 5432 contained within the body 5410 of the light bulb changing tool attachment.

[0264] It will be understood that many applications of the vehicle cleaning tool 2800 are possible. Such applications may or may not relate to cleaning a vehicle.

[0265] Referring now to FIG. 49, the power tool system may provide the user the ability to use a wide range of tools at a distance thereby providing an ability to do work from a standing position that would otherwise require a ladder. While some of the tool attachments may require additional mechanisms to reformat the drive characteristics and other contributing electromechanical elements to do their job, a number of the tool attachments may utilize the direct rotational drive of the power tool system power head with little or no modification save the addition of an attachment mechanism. These direct drive tool attachments 4900 form a compact family of products that connect to the power head of the power tool system by a range of different tool chucks many of which are familiar in the tool industry. The range of applications for such a tool family include simple drilling and fastening 4902 using ubiquitous tools such as twist drills 4914, spade bits, augers and forstener bits and drivers such as flat-blade, Phillips, square-drive and specialty bits. Other applications include cleaning implements 4908, as for vehicles, wherein a range of end effecters such as rotary circular brushes, rotary buffing and polishing pads, and specialty detailing brushes can make the job much easier on today's larger vehicles 4924. In addition, there are direct drive implements for lawn and garden 4912 care such as earth augers to create holes for bulb planting. All this range of tool types consist of a basic tool that need only be connected to the rotational drive of the power head by a mechanical attachment mechanism. Such attachment mechanisms may include a three-jaw chuck 4920, either with a chuck key or keyless, a detent-action hex chuck 4932 or in some cases a chuck with reduction gearing such as an in-line planetary gearhead 4944 that reduces rpm and increases torque in response to certain tool requirements. For drilling and fastening applications using ubiquitous tools such as twist drills, spade bits, augers and forstener bits and drivers such as flat-blade, Phillips, square-drive 4918 and specialty bits a standard three jaw chuck may permit the highest flexibility to accommodate the wide range of possible tools and fasteners. The three-jaw chuck 4920 may be direct coupled to the power tool system power head by a connection plate 4922 that provides registration features to align mechanical components and resist torque couples and slip free engagement of the power output shaft to the input shaft of the chuck assembly. With many other tools, a hex shaft coupling may be the preferred mechanism to transfer power in a drive train. There are many mechanisms for engaging the hex shaft of a tool shank and these are utilized by the power tool system to engage a wide range of such tools. Often it is advantageous to provide power at ninety degrees on inclination to the work piece 4924 and one of the tool chucks for the power tool system may utilize a ninety degree hex shaft chuck 4934 with a ball detent retention of the hex shaft of the tool within the chuck 4932 itself. There are many means of retaining the hex shaft of the tool including mechanical locks, magnetic latches, external locks, screw threads, and others. The hex shaft chuck assembly is attached to the power tool system power head by a connection plate 4940 that provides registration features to align mechanical components and resist torque couples and slip free engagement of the power output shaft to the input shaft of the chuck assembly. Many special cleaning implements are part of the system, all which may utilize the hex shaft to provide high-torque rotational drive to the various cleaning implements. Some flat rotational brushes, polishing and buffing wheels may use the same circular cleaning disc 4930 with the cleaning/buffing/polishing pads 4928 fastening to that disc. Others may be self-contained dedicated cleaning implements that direct connect to the hex chuck. Some tools may require higher torque and lower speeds although they may still utilize a direct rotational drive from the power head of the power tool system. An in-line planetary or other kind of gearbox 4944 may reduce the rpm and increase the torque in a very compact form factor. The in-line gearbox assembly may be attached to the power tool system power head by a connection plate 4948 that provides registration features to align mechanical components and resist torque couples and slip free engagement of the power output shaft to the input shaft of the chuck assembly. The in-line gearbox 4944 connects with a hex-drive chuck or a three-jaw chuck utilized downstream from the gearing to couple the tool such as an earth auger bit 4942.

[0266] Referring now to FIG. 50, the power tool system may provide the user the ability to use a wide range of tools at a distance thereby providing an ability to do work from a standing position that would otherwise require a ladder. While some of the tool attachments may require additional mechanisms to reformat the drive characteristics and other contributing electromechanical elements to do their job, a number of the tool attachments may utilize the direct rotational drive of the power tool system power head with little or no modification save the addition of an attachment mechanism. Cleaning attachments 5000 for vehicles as well as many other commercial and home applications are among the direct drive tool attachments that form a compact family of products that are part of the power tool system family. The range of applications for cleaning implements, such as for vehicles, require a range of end effecters such as rotary circular brushes, rotary buffing and polishing pads, and specialty detailing brushes that can make the job much easier on today's larger vehicles and in many industrial settings. The power tool system cleaning family may include custom brushes for these particular industrial applications. Attachment mechanisms may include a standard three jaw chuck, either with a chuck key or keyless, a detent-action hex chuck or in some cases a chuck with reduction gearing such as an in-line planetary gearhead that reduces rpm and increase torque in response to certain tool requirements. With most cleaning tools a hex shaft coupling may be the preferred mechanism to transfer power in a drive train. There are many mechanisms for engaging the hex shaft of a tool shank and these are utilized by the power tool system to engage a wide range of such tools. It may be advantageous to provide power at ninety degrees inclination to the work piece. One of the tool chucks for the power tool system utilizes a ninety degree hex shaft chuck with a spring-release ball-detent retention of the hex shaft of the tool within the chuck itself. There may be many means of retaining the hex shaft of the tool including mechanical locks, magnetic latches, external locks, screw threads, and others. The hex shaft chuck assembly may be attached to the power tool system power head by a connection plate that provides registration features to align mechanical components and resist torque couples and slip free engagement of the power output shaft to the input shaft of the chuck assembly. Many special cleaning implements may be part of the system and all may utilize the hex shaft to provide high-torque rotational drive to the various cleaning implements. Surface cleaning 5002 may be addressed by a range of custom circular brushes 5010 that are either one-piece molded to the circular drive platform 5012 or assembled as a component system. These circular brushes may provide rotational scrubbing when attached to the right-angle drive 5018 of the direct coupled hex chuck 5014. Surface buffing and polishing 5004 may be addressed by a range of circular buffing and polishing pads 5020 that attach to a one-piece molded circular drive platform 5022. These circular pads provide rotational motion that applies and works the various compounds typically used in vehicle surface care. The range of hex shaft pads attach to the right-angle drive 5028 of the direct coupled hex chuck 5024. There are many other modes of cleaning wherein specialty brushes 5008 ease the task both for vehicle cleaning and in the commercial/industrial setting. The power tool system may utilize a wide range of custom brushes 5030 that may make it easy to clean convolute surfaces such as vehicle wheels 5032. These custom brushes may utilize a hex shaft central spine and attach to the power head drive via a hex chuck 5034. In these custom cleaning applications the orientation of the cleaning head may be important and the right angle drive may be replaced with an adjustable angle drive 5038 utilizing a ring bevel gear coupling a double bevel gear on the input and output shaft as described herein. The range of hex shaft cleaning tools may attach to the right-angle drive 5038 of the direct coupled hex chuck 5034.

[0267] Generally speaking, in an embodiment, a user may obtain the power base and functional modules separately. For example, a retailer may sell the power base separately from the functional modules. In another example, a tool rental center may rent the power base and functional modules separately, if for example, a user may already have a power base and have need only for a particular functional module. In another example, the functional modules may be purchased as needed enabling a user to lower the cost of ownership. In an embodiment, the multi-functional power tool system may be useful residentially, industrially, commercially, may be rented, may be leased, and the like.

[0268] In an embodiment, the power base and one or more functional modules may be obtained as a kit. For example, a power base may be packaged for sale with a module, such as a power base with a pruning shear, a power base with a gutter cleaning device comprising impellers, a power base and a powered paint roller, and the like. In an embodiment, a power base may be packaged for sale with more than one functional module. The functional modules in the kit may be related. For example, a landscape/gardening kit may comprise a power base and functional modules such as a pruning shear, fruit picker, broadcast spreader, and the like. The functional modules in the kit may be unrelated. For example, a kit may comprise a power base and functional modules such as a gutter cleaning device comprising impellers, drill/driver with remote interchangeable bits, a weed whacker, and the like.

[0269] Any and all of the functional modules may be attached to a power head via a quick-release coupling. Any and all of the functional modules may be augmented with, attached to, and/or used in conjunction with a digital wireless video/still camera or any other kind of electronic camera. Such a camera may provide a user with a view of an operational site at which a functional module is being employed. Many examples of this may be described herein and elsewhere, and various other examples of this will be understood.

[0270] While the invention has been disclosed in connection with the preferred embodiments shown and described in detail, various modifications and improvements thereon will become readily apparent to those skilled in the art. Accordingly, the spirit and scope of the present invention is not to be limited by the foregoing examples, but is to be understood in the broadest sense allowable by law.
