Portable jumper system and method

[0001] 1. Field of Invention

[0002] This invention relates to portable jump starters and, more particularly, to a portable jump starter having improved features for illumination, communication and notification all in a single portable device.

[0003] 2. Description of the Related Art

[0004] Rechargeable portable battery chargers and portable DC power supplies have been around for many years. These devices typically provided a housing and jumper cables coupled to a battery situated in the housing. The portable chargers were used to jump start vehicles.

[0005] In one jump starter of the past, the starter had a voltage gauge and a DC outlet so that DC appliances could be plugged into the starter and operated using power from the battery stored in the charger.

[0006] The clamps on the cables were typically stored in a position such that the clamps were clamped onto posts mounted on the housing and any manner that required the operator to compress the clamps while simultaneously moving them downward toward the base of the housing. This was oftentimes troublesome depending on where the housing was situated and upon the physical strength of the user.

[0007] In some prior art chargers, a stationery light was also provided to provide illumination from the charger. Unfortunately, the stationery light of the chargers in the past was not adjustable, which sometimes meant that the charger had to be aimed at, for example, a battery to be charged. This was oftentimes difficult if a user was simultaneously trying to place a clamp on a terminal of the battery.

[0008] One type of battery charger is the model JUMP IT available from Prestone Products Corporation of Connecticut.

[0009] Another problem with the devices of the prior art was that they were limited in their capabilities. For example, if the device was taken during a trip, such as a vacation, hiking, or camping trip, the devices provided no means of communicating or notifying others, particularly in the event of an emergency.

[0010] Therefore, what is needed is a single system for providing not only the operations known in the past but also other features, such as adjustable illumination, notification (including communication and global positioning information) and emergency notification capability all in a single portable system.

[0011] It is therefore, a primary object of the invention to provide a single integrated system and method for providing a starter having multiple features, including the ability to adjustably direct a light source on the starter, optionally house one or more communication devices, such as cellular phones, radios, walkie-talkies, or a global positioning system.

[0012] Another object of the invention is to provide a system and method for providing an external illuminator, which may be adjusted in a vertical position such that the starter can be positioned and then the external illuminator can be adjusted.

[0013] Another object of the invention is to provide an internal illuminator for illuminating the housing and, if desired, providing a colored housing so that the housing may operate as a notification or warning device. It is another object of the invention to provide a strobing circuit for causing either or both of the internal and external illuminators to flash or strobe as desired.

[0014] It is another object of the invention to improve the storing of the clamps so that they may be stored in holsters in an upright and closed position so that they can be easily removed from the starter.

[0015] In one aspect, this invention comprises a portable jump starter comprising: housing for receiving a battery; a jumper for coupling said battery to a power-consuming device; said jumper comprising a plurality of jumper clamps, with each of said plurality of jumper clamps being movable from a closed to an open position; and at least one holster for receiving said jumper clamps while said plurality of jumper clamps are in said closed position.

[0036] FIG. 14 is a schematic view of various features and processes of the invention.

[0037] Referring now to FIG. 1, a portable jump starter or starting system 10 is shown. The portable jump starter 10 comprises an integrally molded, two-piece housing 24 having a handle 26 with finger grips for facilitating carrying the portable jump starter 10. As illustrated in FIG. 3, the housing 24 comprises two halves, halve 24h1 and halve 24h2. After a battery 18 is situated between halves 24h1 and 24h2, the halves 24h1 and 24h2 are secured together with either detents (not shown) or screws 19 (FIG. 2).

[0038] The portable jump starter 10 comprises a first jumper cable 14 and a second jumper cable 16 having a first jumper clamp 20 and a second jumper clamp 22, respectively. During use, the jumper clamps 20 and 22 are coupled to a power-consuming device (not shown), such as a dead battery or other electronic device.

[0039] The housing 24 has at least one holster comprising a first holster 30 and a second holster 32 for receiving the first clamp 20 and the second clamp 22, respectively.

[0040] As best illustrated in FIGS. 7-9, the holsters 30 and 32 are either integrally molded into housing 24 or separately molded and then fastened to a first side 24a and a second side 24b, respectively, of housing 24. For ease of illustration, the holsters 30 and 32 will be described relative to holster 32, but it should be understood that holster 30 comprises the same features. In one embodiment of the invention, the holsters 30 and 32 are separately molded with a receiving area 37, which receives detent 39 (FIG. 1) on clamp 22, thereby retaining the clamp 22 in a stored position. Alternatively, and as shown in FIG. 7, the holster 32 could be molded with one or more detents 36 or 38 that are received in finger recess areas 22a1 and 22b1. The holster 32 has a flange 32a (FIG. 1) that is secured to one of the halves 14h1 and 14h2 with screws 17. Screws 19 secure and retain the holster 32 in place.

[0041] As illustrated in FIG. 7, holster 32 provides a receiving area 34 for receiving and storing clamp 22 such that grips 22a and 22b of clamp 22 are situated adjacent housing 24 and in a vertical and upright manner. In this regard, the holster 32 comprises a plurality of detents, 36 and 38 that cooperate with the grips 22a and 22b, respectively, to secure and retain the clamp 22 in the stored position, as illustrated in FIG. 7. Notice that each grip 22a and 22b comprises a finger recess area 22a1 and 22b1, respectively, which in the second embodiment receives the detents 36 and 38 to facilitate retaining the clamp 22 in the stored position. When it is desired to remove the clamp 22 from the holster 32, for example, a user simply pulls the clamp 22 in the direction of arrow B in FIG. 7.

[0042] Although the embodiment being described herein comprises a plurality of holsters 30 and 32 situated on sides 24a and 24b, respectively, it should be appreciated that more or fewer holsters may be provided as needed. For example, the housing 24 may be provided (not shown) with a single holster (not shown) for receiving the clamps 20 and 22. Thus, a unique feature of the invention is that the housing 24 comprises at least one holster for storing the clamps 20 and 22 in an upright position (as illustrated in FIG. 2) so that they can be easily stored and removed from housing 24 during use.

[0043] Advantageously, this holster 32 and clamp 22 arrangement facilitates storing and retaining the clamps so that the grips 22a and 22b, for example, are in an upright manner (as viewed in FIGS. 1, 2, and 7) so that they can be easily stored and removed from the holster 32.

[0044] As best illustrated in FIGS. 1 and 2, the housing 24 may comprise a plurality of inmolded cable channels, such as channel 40 in FIG. 1, for receiving and storing cable 16 when the clamps 20 and 22 are not being used. Although not shown, the channels may comprise a plurality of detents or other means (not shown) for facilitating retaining the cables 14 and 16 in the stored position.

[0045] As best illustrated in FIGS. 7 and 10, notice that the housing 24 is inmolded to define at least one of a plurality of feet, such as feet 42 and 44. Notice in FIG. 10 that foot 42 comprises a front portion 42a and a heal or back portion 42b and foot 44 comprises a front portion 44a and a heal or back portion 44b. The heal portions 42b and 44b slightly bias the weight of the portable jump starter 10 toward the front portions 42a and 44a, respectively, in order to facilitate balancing the portable jump starter 10 so that it does not fall over during use. As best illustrated in FIG. 7, the front portions 42a and 44a of feet 42 and 44, respectively, extend beyond a front panel or side 24c a distance D1 that further facilitates stabilizing the portable jump starter 10 during use. Likewise, the heal or rear portions 42b and 44b extend beyond the rear panel 24d a distance D2 which also facilitates stabilizing the portable jump starter 10.

[0046] As best illustrated in FIGS. 3-6, the portable jump starter 10 comprises at least one adjustable external illuminator 50 coupled to a switch 52. The external illuminator 50 is mounted in a recessed area 57 defined by a concave wall 24e (FIGS. 5 and 6) in housing 24. The wall 24e comprises a slot 54 for receiving a light bulb 56 on a first side 24e1 and a socket 58 and a retaining spring 60 on a second side 24e2 of wall 24e in order to retain the bulb 56 in the recessed area 57. In this regard, the retaining spring 60 is wider than slot 54 and adjustably secures the bulb 56 in the recessed area 57. A plurality of friction stops or detents 66 and 68 may be integrally molded into a rear side 24e1 of wall 24e. In the embodiment being described, the socket 58 is press-fit between the detents 66 and 68. While the detents 66 and 68 engage the socket 58 and hold it in place, they do permit the socket 58 to pivot between them in order to permit the bulb 56 to be adjusted. The friction stops or detents 66 and 68 retain the bulb 56 in a fixed position after adjustment so that it does not move, for example, during use or transportation of the portable jump starter 10.

[0047] It should be appreciated that slot 54 in the wall 24e permits the bulb 56 to be manually adjusted in a vertical plane 64 (FIG. 4), so that the light illuminated from the bulb 56 can be directed by a user as desired. In the embodiment being described, the light can be adjusted in a vertical plane 64 at an angle of about 40 degrees, as illustrated in FIG. 6. In the embodiment being described, the bulb 56 arrangement may be a General Electric 194 bulb or a Westinghouse 194 bulb.

[0048] Although not shown, it should be appreciated that the invention contemplates the use of an adjustable illuminator (not shown) that permits infinitely variable adjustment in either the vertical plane 64 (FIG. 3), a horizontal plane HP (FIG. 4), or in any other plane as desired. It has been found that adjustment in the vertical plane 64 is most useful when a user uses the external illuminator 50 to illuminate, for example, an engine or trunk compartment of a vehicle or while the user examines an undercarriage of the vehicle. It is also contemplated that a removable illuminator (not shown) could be provided so that the external illuminator 50 may be temporarily removed from the housing 24 to provide a convenient flashlight. In this regard, a user may hold the handle 26 to carry the portable jump starter 10 with one hand while holding and directing the removable external illuminator 50 (not shown) with the other hand as desired. In the embodiment being described, the external illuminator 50 may be directly wired to the battery 18 or it may be rechargeable so that when it is mounted in a cradle (not shown) on housing 24, it becomes recharged over time by battery 18.

[0049] In this embodiment, the portable jump starter 10 comprises a strobe circuit 51 that is coupled to the switch 52 and illuminators 50 and 78 (described later) to cause one or both of the illuminators 50 and 78 to blink or flash at a desired rate, such as 60 flashes per minute. The user may actuate switch 52 into a flashing light or strobe mode during which the external illuminator 50 is caused to blink or flash on and off at a predetermined rate.

[0050] The portable jump starter 10 may further comprise a plurality of transparent and colored bezels 55 (FIG. 3) that may be detachably mounted over external illuminator 50. The bezels 55 may be, for example, orange, yellow, or red to provide a colored light or beacon or may be clear. As shown in FIG. 6, each bezel 55 is threaded allowing it to be detachably mounted to bulb housing 61.

[0051] The portable jump starter 10 further comprises a voltage gauge 70 having an associated test button 72 which is mounted into housing 24 and which provides means for testing the voltage level of the battery 18 (FIG. 2).

[0052] The portable jump starter 10 further comprises notification means or a notifier 75 (FIG. 1) for notifying and/or communicating various information, such as a location or position of the portable jump starter 10, emergency information, or other emergency information. In one embodiment of the invention, the notification means or notifier 75 comprises a reflective label 76 situated on the front panel 24c of housing 24, as illustrated in FIG. 1. It should be appreciated that the reflective label 76 may be positioned on sides 24a, 24b, or even on the rear panel 24d as desired. It is also contemplated by the invention that the reflective label 76 could be integrally molded into the housing 24. While this notifying feature of the invention has been described by use of the reflective label 76 situated on housing 24, it should be appreciated that other graphics or signage could be provided on the outer surface 25 of housing 24 in order to achieve the notification function.

[0053] The notification means or notifier 75 may also comprise an internal illuminator 78 coupled to the battery 18 and switch 52. The internal illuminator 78 comprises a socket 80 that is mounted or inmolded onto an interior surface 27 of housing 24. A bulb 81 is received in socket 80 whenever it becomes coupled to switch 52 (FIG. 1). In this embodiment, switch 52 is a multi-function switch actuable to energize external illuminator 50 and/or internal illuminator 78 either separately or in combination.

[0054] In the embodiment being described, the housing 24 is a plastic molded construction having a thickness of about 0.13 inch. When the switch 52 is actuated to energize internal illuminator 78, the housing 24 becomes illuminated. Also, the housing 24 is molded to comprise a predetermined color, such as safety orange, red, yellow, green or camouflage. Thus, when the internal illuminator 78 is energized the housing 24 becomes illuminated externally to glow a predetermined color. The internal illuminator 78 is also coupled to strobe circuit 51 so that the light from bulb 81 can be strobed upon actuation of switch 52.

[0055] Advantageously, the internal illuminator 78 provides means for illuminating the housing 24, which provides a convenient safety illumination that can be used in combination with or in replacement of, for example, traditional road flares. In operation, the user actuates the switch 52 and this causes battery 18 to energize bulb 81. The user then places the portable jump starter 10 at a desired position, such as behind a disabled vehicle (not shown) on a side of a road, in order to warn vehicle traffic of the disabled vehicle.

[0056] The user may actuate the switch 52 to simultaneously energize both the external illuminator 50 and the internal illuminator 78 in order to provide both external and/or internal illumination, respectively. As mentioned earlier, the colored covers may be mounted over the external illuminator 50 to provide colored light. Advantageously, when the user actuates switch 52 to cause external illuminator 50 to operate in a strobe mode, the colored light provides for example, a flashing warning light. When used with the internal illuminator 78, a powerful emergency notice is provided. The housing 24 may be provided with one or more windows (not shown) in order to permit the internal illuminator 78 to be used, for example, as a lantern or whenever a direct beam of light of the external illuminator 50 is not desired.

[0057] Referring now to FIG. 11, the notifying means or notifier 75 may further comprise a communication and positioning means or system 82. In the embodiment being described, the internal illuminator 78 comprises at least one communicating or location detection device (such as a cellular phone 84, a walkie-talkie or a two-way radio 86), personal digital assistant (PDA) 87, or a global positioning system (GPS) 88. The housing 24 comprises at least one receiving area 90 for receiving at least one of the devices 84-88. For ease of illustration, a single receiving area 90 is shown for receiving the phone 84, but it should be understood that a plurality of areas 90 could be provided for storing each of the devices 84-88. Also, the housing 24 could be provided without any receiving area 90 if desired.

[0058] At least one receiving area 90 comprising a plurality of detents 91 associated therewith for retaining, for example, the phone 84 in a stored position on the housing 24. The housing 24 may be molded to provide the receiving area 90 having a shape which complements the shape of the device 84-88 so that the front surfaces 84a, 86a, 87a, and 88a will be substantially co-planer with the front panel 24c of housing 24. This further permits the devices 84-88 to be operated while being stored in the housing 24. Alternatively, the devices 84, 86, 87, or 88 may be removed from the housing 24 using finger recess 90a.

[0059] Although not shown, the positioning means or system 82 comprising the devices 84-88 may be provided (i.e., rather than being separate, removable devices) as an integral component of the portable jump starter 10. In the embodiment, the portable jump starter 10 comprises a microphone 90, speakers 92, and an electronic pad or keyboard 94 that are either mounted on or inmolded into housing 24. The components 90-94 are coupled to communication circuitry that is energized by battery 18 to provide cellular phone capability, two-way radio/walkie-talkie capability, and/or global positioning system capability.

[0060] As illustrated in FIG. 1, the portable jump starter 10 also comprises a DC outlet plug 100 having a cap 101 which may be opened to permit access to a female DC receptacle for receiving a standard male DC receptacle for powering DC components, such as radios, hair dryers, battery rechargers, external lights, and the like.

[0061] The portable jump starter 10 further comprises recharging means or a charger 106 for recharging the battery 18 stored in the housing 24. The charger 106 comprises a plurality of male plug terminals 108 and 110 that may be received in, for example, a conventional extension cord (not shown) which may be plugged into a conventional AC outlet. As illustrated in FIGS. 2 and 13, the housing 24 may be molded to define a bracket 112 for receiving the charger 106 such that the male plugs 108 and 110 extend in a recessed area 114. A cap 116 is pivotally mounted to housing 24 and covers the area 114 when the male plugs 108 and 110 are not being used. The charger 106 is permanently coupled to the battery 18 and charges the battery 18 when it is coupled to a conventional AC outlet via, for example, a conventional extension cord (not shown). In the embodiment being described, the charger 106 is a conventional 12V 500 mA, TDNA model HD-1250-WH, available from Technical Devices of North America, Inc. of Dayton, Ohio.

[0062] Advantageously, this invention provides a power source and portable jump starter 10 whose most basic function is to provide a power source for many different applications, such as jump-starting a vehicle (such as a boat, automobile, truck, construction equipment, or other vehicle). The device has numerous features for notifying others of a position of the device, via the GPS device 88, or by providing communication means for contacting third parties using the cellular phone 84, walkie-talkie 86, PDA 87, or GPS 88, which, as mentioned earlier, may be integrally molded into the portable jump starter 10.

[0063] During a jump-start operation, a user may carry the portable jump starter 10 and situate it near, for example, a battery of a vehicle (not shown) after opening the hood of the vehicle. After adjusting external illuminator 50 (if needed), the jumper clamps 20 and 22 are removed from holsters 30 and 32, respectively, and situated on the terminals (not shown) of the vehicle battery so that the engine of the vehicle may be started. If necessary, portable jump starter 10 switch 52 may be actuated by the user to energize external illuminator 50, thereby enabling the portable jump starter 10 to be used similar to a portable light source or flashlight.

[0064] As alluded to earlier, the user may also actuate switch 52 to cause the internal illuminator 78 (FIG. 2) to become energized, thereby illuminating the housing 24. Once illuminated, the portable jump starter 10 may be positioned like a road flare to provide a safety beacon as may be desired by the user. As also mentioned earlier herein, to further facilitate this safety feature, the housing 24 may be molded to be a predetermined color (such as safety orange, yellow, or red) so that when switch 52 is actuated to energize internal illuminator 78, the housing 24 becomes illuminated.

[0065] Referring now to FIG. 14, a schematic is provided to illustrate various features and processes of the invention that may be used alone or in combination. Initially, a user will select a desired action, for use of the portable jump starter 10. For example, the user may select one or more of the following operations: to provide jump start (block 100), to actuate the internal illuminator 78 and/or external illuminator (block 102), to test the battery 18 (block 104), to provide power to a DC device (block 106), power to an AC device (block 108), to notify others of a position (block 110), to communicate with others (block 112), or to recharge the battery 18 in the portable jump starter 10 (block 114). After selecting one or more modes of operation 100-114, various procedures are followed and these procedures will be explained in the order in which they appear in FIG. 14. However, it should be appreciated that the modes of operation 100-114 may each be selected alone or in combination and in any desired order.

[0066] Beginning with the jump-start procedure selected at block 100, the user positions the portable jump starter 10 near a battery or other power source to be provided with power from battery 18 (block 116). If it is dark or if the user requires light, the user may actuate switch 52 to energize an external illuminator 50 and/or internal illuminator 78 in accordance with the light mode sequence beginning at block 102). Thereafter or if the user does not wish to energize a light, the routine proceeds to block 121 where the user positions the clamp 22 on the power-consuming device, such as a battery to be charged, at block 121. At block 122, the battery provides enough power so that the user may attempt to start the engine of the vehicle.

[0067] The user actuates switch 52 to energize illuminators 50 or 78 in either a regular or flashing mode. One sequence for doing this is illustrated in FIG. 14, where the user begins by determining whether he desires to illuminate the external illuminator 50 (decision block 124) and if he does, then he would actuate switch 52 accordingly (block 126). If the user determines at decision block 124 that he does not wish to illuminate external light 50, but does wish to illuminate the housing 24 (decision block 128), then he would do so at block 130. If he determines that he does not wish to illuminate the housing 24 (decision block 128) or after doing so at block 130, the user may wish to cause one or both illuminators 50 or 78 to operate in the flashing or strobe mode (beginning at decision block 132) in which case the user actuates the switch 52 (block 134). If the decision at decision block 132 is negative after the user has actuated the switch 52 at block 134, then the user positions the housing 24 where desired.

[0068] If a battery test mode (block 104) is desired, the user depresses the test button 72 and observes the voltage gauge 70 in order to determine how much voltage is left in battery 18 (block 136).

[0069] If the user elects to power a DC device (block 106), then the user simply plugs a male connecter (not shown) of the DC device (not shown) into outlet 104 (block 138). Thereafter, the user may operate the DC device at block 139. If a user elects to power an alternating current (AC) device, the user connects a DC to AC inverter (not shown) in outlet 104 (block 140). Thereafter, the user connects the AC device to the inverter (block 142) and operates the AC device as desired.

[0070] If the user wishes to notify others of his position (block 110), then the user removes the GPS device 88 from housing 24 (block 144) and uses the device to determine his position (block 146). If the GPS device 88 is provided as an integral component of the portable jump starter 10, then the user simply uses the GPS device 88 as integrally provided in the portable jump starter 10 (without removing it from the housing 24).

[0071] If the user desires to communicate with others (block 112), then he selects the radio device 86 or phone device 84 (block 148) and uses the selected device 84 or 86 as desired.

[0072] Finally, if battery 18 needs to be recharged, then the user plugs an AC cord onto plugs 108 and 110 (block 152) and thereafter charges the battery 18 (block 154).

[0073] Advantageously, this portable jump starter 10 provides an improved combination of features and components. The system provides improved means for storing jumper clamps 20 and 22 in the holsters 30 and 32 that are either attached or integrally molded in housing 24. The system provides numerous safety features, such as the adjustable external illuminator 50 and internal illuminator 78, as well as the flashing mode sequence all of which can be actuated using the single switch 52. The notifier or notification means in the form of the reflective label 76 also provides a significant safety feature which, when used alone or in combination with the strobe or flashing light sequence, can provide a significant visual warning to, for example, approaching vehicle traffic. The portable jump starter 10 further provides the adjustable external illuminator 50 which can be adjustably positioned in a vertical plane 64 so that the user can adjust and direct the light from external illuminator 50. This has been found to be particularly useful when the portable jump starter 10 is situated, for example, near an engine compartment with the light from external illuminator 50 directed toward the battery to be jumped in order to make it easier for the user to position the jumper clamps 20 and 22 on the battery.

[0074] Moreover, the GPS 88 and communication system stored or mounted on portable jump starter 10 provides means for determining a users position, as well as enabling a user to communicate with others. These features are believed to have significant advantages when the portable jump starter 10 is taken while traveling in a vehicle or on a boat. The portable jump starter 10 is also suited for camping or other recreational activity or even business activity, such as on a construction job or at home.
