Abstract

A self-contained rechargeable device, such as a flashlight, utilizing a rechargeable source of electrical energy, such as rechargeable batteries, and including a pivotally mounted connector for connecting the battery and any recharging circuit connected thereto to a source of recharging energy when positioned in a recharging position and, alternatively, having a standby position internally of the device in which the connector enables a circuit between the source of energy and a load to be operated thereby. The circuit is completed by operation of a manually-operated switch connected between the energy source and the load. The load is totally disconnected from the battery during recharging. A manually-operated actuator effects movement of the connector generally between the charging position, wherein the connector completes a circuit between the rechargeable batteries and a potential source of electrical recharging energy in the standby position where the connector enables the circuit between the batteries and the load and an position wherein the actuator operates the manual switch for energizing the load.

Claims

1. A rechargeable device comprising:

a battery-operated load;

a rechargeable battery means adapted to provide power to said load;

connector means selectively positionable in a first recharging position for effecting connection of said battery means to a source of recharging energy and in a second standby position for providing a connection circuit between said battery means and said load;

said connector means including first and second conductive connector members for effecting a connection between said battery means and said energy source when said connector means is in said recharging position;

one of said connector members being operable to provide a connection between said battery means and said load when said connector means is in said standby position; and

switch means operable to complete a circuit between said battery means and said load for energizing said load when said connector means is in said standby position.

2. A device as claimed in claim 1, wherein:

said load is connectable to said battery means through said switch means and said one conductive connector member when said connector means is in said standby position, and said load means is disconnected from said battery means when said connector means is in said recharging position.

3. A device as claimed in claim 1, including:

first contact means, said first contact means being connected to one terminal of said battery means and being engageable by said second connector member when said connector means is in said recharging position for effecting connection between said connector member and said one terminal of said battery means.

4. A device as claimed in claim 3;

wherein said first contact means includes a first contact portion engageable with said second conductor member for effecting electrical connection thereto when said connector means is in said recharging position;

said first contact including a second contact portion engageable with said first connector member for connecting said first connector member to said one terminal of the battery means when said connector means is in said standby position.

5. A device as claimed in claim 4, including;

second contact means connected to a second terminal of said battery means and engageable by said first connector member when said connector means is in said recharging position for completing a circuit from said first connector member to said second terminal of said battery means for effecting connection of the battery means to a source of recharging energy.

6. A device as claimed in claim 5, including;

recharging circuit means connected between said second contact means and said second terminal of said battery means.

7. A device as claimed in claim 6, including;

third contact means connected to said second terminal of said battery means, and wherein said recharging circuit is connected between said second and third contact means.

8. A device as claimed in claim 7, including;

fourth contact means connected to a second terminal of said load means and defining with said third contact means manually-operated switch means.

9. A device as claimed in claim 1, including;

manually-operated actuator means engageable with said connector means for effecting movement thereof to enable positioning thereof in said standby and recharging positions.

10. A device as claimed in claim 9, wherein;

said connector means includes a non-conductive body means;

cam means formed on said body means;

and wherein said actuator means includes means engageable with said cam means for effecting said movement of said connector means to enable positioning thereof in said recharging and standby positions.

11. A device as claimed in claim 10, wherein;

said actuator means is movable between a first recharging position and a second standby position, said means on said actuator means engageable with said cam means for effecting movement of said connector means towards said recharging position in response to movement of said actuator means into said recharging position.

12. A device as claimed in claim 11, wherein;

said means on said actuator means is engageable with said cam means for effecting movement of said connector means from said recharging position to said standby position in response to movement of said actuator means from said charging position to said standby position.

13. A device as claimed in claim 12, wherein;

said device includes detent means engageable with said cam engaging means on said actuator means for retaining said actuator in said standby position.

14. A device as claimed in claim 13, wherein;

said actuator means has a third on position, means on said actuator means engageable with said switch means in response to movement of said actuator means into said on position for closing said switch means and completing the circuit between said battery means and said load means.

15. A device as claimed in claim 14, including;

additional detent means cooperating with said cam engaging means on said actuator means for retaining said actuator means in said on position.

16. A device as claimed in claim 1, wherein;

said connector means is pivotally mounted for movement between said recharging position where the connector members project out from one surface of said device for connection to a source of recharging energy, and said second standby position wherein said connector members are retained within said housing.

17. A device as claimed in claim 16, wherein;

said conductors are disposed generally parallel to the axis of said device when in said standby position.

18. A device as claimed in claim 17, wherein;

one of said connector members is disposed adjacent the surface of said device when in said standby position, said one connector member being disconnected from all electrical circuitry in said standby position.

19. A device as claimed in claim 18, including;

a manually-operable actuator means movable between a recharging position and a standby position, said actuator means including engaging means cooperative with said connector means for effecting movement thereof from said standby position towards said recharging position in response to movement of said actuator means into said recharging position, and engageable with said connector means for effecting movement thereof from said recharging position into said standby position in response to movement of said actuator means into said standby position.

20. A device as claimed in claim 19, wherein;

said actuator means is a slidable member movable longitudinally of the housing of said device, sadd slidable member covering said connector means in said standby position.
