Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved self-powered pool vacuum with remote controlled capabilities embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the new and improved self-powered pool vacuum with remote controlled capabilities is comprised of a plurality of component elements. Such component elements in their broadest context, include a head, a brush, parallel axles, a drive motor, a steering motor, a receiver, a battery and a control mechanism. Such components are individually configured and correlated with respect to each other so as to attain the desired objectives.
The principal component of the system 10 of the present invention is a head 12. The head has a lower base 14 in a generally rectangular configuration. The lower base has side openings 16 extending vertically through the lower base. The head also has an enlarged leading edge 18. The head also includes an intermediate cover 20. The intermediate cover is positionable over the base and has a central aperture 22 extending there through. The intermediate cover also has an apertured peripheral flange 24 with a gasket 26. The gasket is positionable between the flange and the base for the coupling together of such two components.
The head 12 also includes a top cover 30. The top cover is positionable over the intermediate cover and base. Above the intermediate cover and beneath the top cover is a plenum zone 34. The plenum zone is for the withdrawing of air and water from the leading edge of the base. The top cover also includes an aperture 36 with a flange 38 for coupling with a suction hose 40. In addition, an antenna 42 extends upwardly from a supplemental aperture 44. The periphery of the base and top cover are to coextensive with the periphery of the intermediate base being located interiorly of those components above and below.
The next component of the system is a brush 46. The brush is peripherally positioned to extend downwardly from the lower base. It is preferably coupled thereto through apertures 48 on the upper surface of the base coupling with associated apertures 50 around the periphery of the lower base.
Parallel axles 54, 56 extend transversely through the base. The rearmost axle 56 are a pair of drive wheels 58. Appropriate conventional coupling mechanism provide couplings between the drive wheels and provide flat surfaces 60 on the axles 62 which mate with corresponding flat surfaces on its associated wheels. Such drive wheels are preferably solid rubber tires for improved traction. One drive wheel is located at each end of the axle on opposite sides of the lower base.
Cooperatively associated with the drive wheels are a pair of steering wheels 62. The steering wheels are individually coupled about a vertical axles 64 for varying direction of motion of the device. A steering rod 64 couples the wheel 62 and axle 54 for pivoting the wheels to change direction. This is done through an appropriate combination of conventional linkage components as shown in FIG. 5. All four of the wheels 58 and 60 extend downwardly to an elevational orientation essentially to the lower edge of the brushes.
A drive motor 70 is located in the lower base. The drive motor functions to provide the motive force to the device for cleaning and includes an arrangement of components 72 to rotate the drive wheels. This function is to move the lower base along the floor or the pool for cleaning purposes. Activation and inactivation of the drive motor and other components will be described here and after.
An additional motor, a steering motor 76, is provided with an output shaft having a pinion gear 78, Such pinion gear functions an association with a rack 80 for movement transversely with respect to the direct of motion of the device. Such is used for directing the turning of the wheels 62 through steering rod 66 to insure proper directional motion of the device.
Also located within the head is a receiver 84. The receiver is electrically coupled to the antenna 42 located thereabove. It is also electrically coupled to the steering motor 76 to drive the steering motor as well as the rack in one direction or another in response to signals from the antenna and receiver. The drive motor 70 is also coupled to the receiver 84 for effecting its energization to provide the forward motion of the device during the cleaning activity.
In association with the receiver and motors is a battery 86. The battery is in a sealed container within the base. Its function is for providing electrical potential to power the drive motor and the steering motor during operation and use. It also functions to power the receiver so that it may receive the instructional information for utilizing the device.
The last component of the system 10 of the present invention is a control mechanism 90. The control mechanism is provided with an upstanding joy stick 92. Such joy stick extends in a generally vertical orientation. It is movable to any angular orientation at the discretion of the user. The face of the control mechanism also includes indicia 94. Such indicia is in the nature of the markings L and R to indicate whether a user wishes to have the device moved to the left or the right. The indicia also includes a FWD and a REV to indicate whether the user wishes the device to move forwardly or in a reverse manner. Other two components are an OFF sentences to turn off the device. The last form of indicia is AUTO sentence this is to automatically position the device for movement in a predetermined travel mode, as for example a random travel mode to clean all areas of the pool in which the device is located.
When the joy stick is turned to the off position and allowed to return vertical as by a spring mechanism, the device will remain inoperative. This condition will be maintained until the joy stick is moved to an alternate position whether forward, reverse, left, right or the like as well as automatic as may be desired by the user. Joy sticks are conventional, Their configuration is a function of the number of activities one may wish to be preformed by such joy stick. Such joy stick also has an ON/OFF switch 96. It also has a transmitter and an antenna 98 which is extendable to allow communication between the control mechanism and the appropriate control components in the receiver 84.
The present invention provides a better way to clean a swimming pool. It is a self-powered unit that can crawl along and vacuum, and is controlled in real time by a person outside of the pool. It eliminates the energy, control, and patience required to clean a pool manually while it enables a person to guide the unit so as to clean all areas an unattended robot might miss. The present invention can also operate in an unguided, random path mode.
The present invention consists of a pool cleaning unit and a controller. The cleaning unit is 11 inches high and 12 inches wide, with the flat bottom that has a stiff brush around its periphery. It uses the circulation pump to provide a vacuum, and is connected to the pump by a hose. The brush scrubs the liner and helps maintain the suction between the unit and the liner. Two round projections on opposite sides of the unit fit into the circular ends of a U-shaped handle that is used to lift the unit in and out of the pool.
The cleaning unit preferably contains a 1/3 horsepower DC motor and reduction gears in a waterproof section which drives a pair of rubber wheels that provide the motive power. The drive motor can run in either direction to go forward or backward, and the front wheels can be turned to go to the left or right. The wheels are turned by a small DC steering motor and reduction gears in another watertight section. The direction and on/off state of both motors are controlled by a 2-channel citizens band radio receiver whose antenna is encased in a waterproof sleeve that extends up from the front of the unit. Electrical power is provided by two 9 volt rechargeable batteries in another waterproof section with the receiver. A watertight plug on the side provides connections to a charger.
The controller consists of a round container that houses a 2-channel citizens band radio control transmitter, a joy stick and a battery. The joy stick projects up from the center of the unit. Electrical power is off when the joy stick is in a detent position all the way back and to the left. Moving it from this position turns power on and allows the joy stick to move to its straight up neutral position. Pushing the joy stick forward turns the drive motor on in the reverse direction. Pushing the joy stick to the right turns the wheels right, and pushing it left turns them to the left. Pulling the joy stick back and to the right places it in the automatic mode decent, in which the cleaning unit moves forward until it hits an obstruction, when it reverses and changes course a small amount.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
