Description

BACKGROUND

Rechargeable flashlights are known in which a flashlight containing a rechargeable battery is configured to connect with a battery charger for charging the battery while it remains in the flashlight. Such flashlights are particularly desirable for emergency workers who must depend upon having a readily available source of light at remote locations. Although such flashlights are normally stored in a charging assembly, the battery may become discharged through repeated or extended use if there has not been enough time to fully recharge the battery between uses. In such a situation, it is necessary to return the flashlight to the charger for sufficient time to recharge. During this recharging time, the flashlight is unavailable for use. Thus it would be desirable to provide a rechargeable flashlight system in which an auxiliary battery is maintained in a charged condition so that the discharged battery may be removed from the flashlight and replaced by the auxiliary battery.

It would further be desirable for the auxiliary battery charger to be integrated with the flashlight charger so that the flashlight, the flashlight charger, and the auxiliary battery charger are maintained at a single location. Since many emergency crews already possess rechargeable flashlights, it would be desirable to provide an auxiliary battery assembly capable of being attached to an existing rechargeable flashlight system to provide for the ability to replace a discharged battery in such an existing rechargeable flashlight system.

Flashlights employed by emergency workers are often maintained aboard vehicles, and are used in hazardous locations. It is essential for a rechargeable flashlight system to hold the flashlight securely, and for the flashlight to be watertight and mechanically reliable.

SUMMARY

In accordance with the present invention, there is provided a rechargeable flashlight system which provides a flashlight having a rechargeable battery assembly, a flashlight charger for receiving the flashlight and charging the battery within the flashlight, and an auxiliary battery charger configured to be integrated with the flashlight charger for holding, charging, and maintaining the charge of an auxiliary battery assembly compatible with the flashlight.

The flashlight comprises a body having a central cavity for holding a rechargeable battery. The lower end of the body is closed by a cover member which opens to permit removal of the body. A pair of conductors extends through the cover member for contact with the flashlight charger, which recharges the battery when the flashlight is positioned in a receptacle in the flashlight charger. The lower end of the body is flared to mate with upward and inwardly extending walls of the receptacle by abutment, to securely hold the flashlight in the receptacle during charging.

An auxilliary battery charger is attached to the flashlight charger. The auxilliary battery charger is formed to provide a receptacle for receiving an auxilliary rechargeable battery. A latch mechanism connected with the auxilliary battery charger holds the auxiliary battery securely in the receptacle during charging.

The rechargeable battery comprises a case for holding rechargeable cells. Contacts are provided through the upper end of the case to provide contact with connectors positioned in the upper end of the interior of the body cavity. Contacts are also provided at the lower end of the case to connect with the rear cover member conductors of the flashlight when positioned therein, or with charging contacts positioned in the receptacle of the auxiliary battery charger.

DETAILED DESCRIPTION

Referring now to FIG. 1 there is shown a flashlight 10, a flashlight charger 12, and an auxiliary battery charger 14 holding an auxiliary battery 16 in an assembled configuration. Each of these components is described separately below.

The flashlight 10 is shown separated from the charger 12 in FIGS. 3A and 3B. The flashlight comprises a head assembly 18 and a body 19 having a central cavity therein for receiving a battery assembly. In the head assembly 18, a light bulb 20 is positioned at the center of a reflector 22 which is held in a reflector housing 23. The reflector is positioned at an angle, preferably a right angle, to the central axis of the flashlight. A clip 13 is pivotally connected to the rear of the flashlight. A spring 15 is positioned between the body of the flashlight and the upper end of the clip, so that the lower end of the clip 13 is urged toward the body. The clip 13 and the angled configuration of the flashlight allows the flashlight to be attached to an article of clothing of the user, such that light is projected in the forward direction when the flashlight is worn by the user. A switch 24 is located on the head assembly 24 and is internally connected between the bulb 20 and a battery assembly to selectively connect the bulb with the battery assembly.

The bottom portion of the body 19 of the flashlight 10 comprises a flared portion which provides a lip or rim extending outwardly about the bottom of the body 19 of the flashlight 10. As shown in FIG. 4, the bottom end of the flashlight 10 is closed by a bottom cover member 27. The bottom cover member 27 is attached to the body 19 by a hinge 28 at one side of the bottom cover member. The cover member 27 is held to the body 19 at the other side thereof by a releasable clip 30 which is pivotally held by the cover member 27 to latch onto a latch member 32 formed on the lower portion of the body 19 of the flashlight.

The cover member 27 has a pair of conductors 34a and 34b which extend through the cover member 27, as shown in FIG. 5, to provide exterior charging contacts on the external surface thereof and to conduct electricity to a pair or rear charging contacts located on the battery assembly. The cover member 27 also has a vent hole 36 formed therein for venting gas from an internal check valve member 38 positioned in cover member 27. The valve member 38 is formed of a flexible material and is configured to have a central boss which is compressively held in a hole 37 formed through the interior surface of the cover member 27. The valve member has a widened concave skirt about one end of the boss which is pressed flush against the top end of a vent cavity formed in the cover member. As best seen in FIG. 6, several slits 41 are formed adjacent to the hold 37 to provide a pathway for gas within the flashlight body to flow through the cover member 27 toward the skirt of the valve member. The concave skirt is flexible to allow gas to exit the flashlight body, but provides a seal against gas entering the flashlight body.

The cover member further has an outer rim 44 and sealing surface 44 which extends into the flashlight body when the cover is in the closed position. A groove is formed around the periphery of the sealing surface, and an O-ring 40 is situated in the groove to provide a fluid tight seal between the cover member and the rear opening of the body of the flashlight. As can be seen in FIG. 2, when the flashlight is closed, the clip 30 swings upwardly from the cover member 27 to latch with a projection 50 formed at the lower end of the flashlight body. The O-ring is compressed to form a fluid-tight seal between the cover member 27 and the flashlight body when the clip 30 is engaged onto the latching projection 50.

The flashlight charger 12 is shown separated from the flashlight in FIG. 7. The flashlight charger 12 comprises a body for housing charging circuitry, such as a transformer and a rectifier for converting AC to DC current in applications where such conversion is desired. The upper wall portion 60 of the charger 12 extends upwardly and inwardly to mate with the flared contour of the lower end of the flashlight, and forms a receptacle 62 for laterally receiving the lower end of the flashlight. The bottom surface of the receptacle 62 has a pair of spring-loaded contacts, such as contact 64 shown in FIG. 7, which extend upwardly through the bottom surface of the receptacle to connect with the conductors extending through the bottom cover member of the flashlight. The bottom surface of the receptacle 62 has a lateral extent larger than the bottom surface of the flashlight, and has a spring-loaded latch member 66 extending upwardly at the flashlight-receiving side of the receptacle 62. As the flashlight is laterally inserted into the receptacle 62, the latch member 66 is depressed by the bottom of the flashlight as it slides over the latch member 66 into the receptacle. When the flashlight is fully inserted into the receptacle, the latch member 66 is again pushed upwardly by a spring mounting within the charger 12 in order to secure the flashlight into the receptacle 62, as can be seen in FIG. 2. In order to remove the flashlight from the receptacle, the latch member 66 is depressed by the user to permit the bottom of the flashlight to slide over the latch member and out of the receptacle.

Referring again to FIG. 7, the auxiliary battery charger 14 is shown separated from the flashlight charger 12. The auxiliary battery charger 14 has a mating surface 70 which is configured to conform with a rear surface of the flashlight charger 12. To attach the auxiliary battery charger 14 to the flashlight charger 12, a pair of openings 72 are formed in the rear surface of the flashlight charger 12 to receive a pair of engaging members 74 connected to the mating surface 70 of the auxiliary battery charger 14. Prior to mechanical engagement of the auxiliary battery charger 14 and the flashlight charger 12, charging circuitry within the auxiliary battery charger 14 is connected in parallel with the charging circuitry of the flashlight charger 12 by a pair of wires (not shown) which pass from the auxiliary battery charger 14 into an existing connector via 76 in the rear of the flashlight charger. The projections 74 are then inserted into the holes 72, and the mating surface of the auxiliary charger may be further secured to the flashlight charger by adhesive. An electrical connector 78 is seated within the rear end of the auxiliary battery charger 14 to provide electrical connection to an external source of electricity, such as AC line current or a vehicular DC electrical system. It will be appreciated that the flashlight charger and the auxiliary battery charger may be connected together as shown or, in alternative embodiments, may be manufactured as an integrated unit.

The auxiliary battery charger 14 is shown in cross section in FIG. 9. A latch member 80 is mounted in one side of the charger 14 by a pivot 83. A spring 84 is positioned between an interior surface of the charger 14 and the upper end 81 of the latch member 80. The upper end 81 of the latch member 80 extends to the exterior of the charger 14. The lower end of the latch member 81 has an engaging projection 82 formed thereon and extending into the receptacle for engagement with compatible notch formed in the battery assembly and discussed below. Pressing upon the upper end 81 of the latch member 80 compresses the spring and moves the engaging projection 82 out of the receptacle in order to permit removal of the battery assembly from the receptacle.

The battery assembly 82 is shown in FIG. 10 positioned within the flashlight 10. The battery assembly comprises a case or shell 84 having an upper portion 84 and a lower portion 86 which are joined together to house several rechargeable cells 88a-d. A notch 85 is formed in the lower portion 86 of the case 82, 84, 86 for engagement with the latching member 80 of the auxiliary battery charger 14 when the battery assembly 82 is inserted into the auxiliary battery charger 14. The rechargeable cells 88a-d are preferably cylindrical cells, which are arranged in respective series pairs 88a-b and 88c-d. The series pairs 88a-b, 88c-d are physically positioned adjacent to each other within the case 84, 86 in parallel, and are each wrapped in respective insulating paperboard jackets 90a and 90b which are secured to each other by an adhesive 92. A conductor strip 94 is connected to the respective lower ends of the series pairs 88a-b and 88c-d to connect all of the cells 88a-d together in electrical series such that respective negative and positive contacts 96a and 96b are positioned at the upper end of the battery assembly 82. Openings 98a and 98b are formed in the upper end of the case 82 to allow electrical contact between the contacts 96a and 96b and respective spring conductors 100a and 100b, which are connected to the head assembly 18 of the flashlight 10 and which conduct electrical current to the bulb 20.

The lower portion 86 or rear end member 86 of the case 82 has a circuit board 102 positioned therein. A pair of springs 104a and 104b are electrically connected to the circuit board 102 and extend outward from the bottom of the battery assembly 82 for engagement with the conductors 34a, 34b positioned in the cover member 27 of the flashlight 10. It will be appreciated that, in the assembled condition, the battery assembly 82 is thus insulated from physical shock due to its positioning between springs 100a-b of the flashlight 10 at the upper end of the battery assembly 82, and springs 104a-b of the battery assembly 82 at the lower end thereof. A pair of conductors 105a and 105b are electrically connected with the springs 100a and 100b via the circuit board 102.
