Abstract

The battery charger provides a current to a battery depending on its type. The type of the battery is determined using, in the preferred embodiment of the invention, a two-pronged fork and a pusher slider assembly which may actuate two switches using a spring leaf. The two switches enable to provide a current depending on the type of battery. In the preferred embodiment of the invention, AAA-type, AA-type, C-type and D-type batteries may be used. The invention also enables to easily position the battery in the battery charger.

Claims (16)

1. A battery charger receiving at least one battery horizontally on a support surface and having at least one switch detecting a variable battery size and a charging circuit responsive to said at least one switch, characterized in that:
said switch comprises a first pair of depressible posts, the first pair of depressible posts biased with respect to the support surface of the battery charger, said posts being spaced to. guide the battery therebetween to be centrally positioned on the support surface and be depressed depending on a size of the battery.
2. The battery charger as claimed in claim 1, wherein the first pair of depressible posts is provided by a two-pronged fork, the two-pronged fork actuating a first switch and a biasing action of the fork helping to center the battery when depressed.
3. The battery charger as claimed in claim 2, wherein said two-pronged fork moves in a vertical plane to said support surface to actuate said first switch.
4. The battery charger as claimed in claim 3, wherein said two-pronged fork pivots about a fixed axis, moving rotatively in a substantially vertical plane, to actuate said first switch.
5. The battery charger as claimed in claim 1, further comprising a second switch, the second switch being actuated by a moveable part, the moveable part maintaining said battery electrically connected with said battery charger.
6. The battery charger as claimed in claim 5, wherein said second switch is being actuated using a spring leaf, the spring leaf being connected to the second switch and to the moveable part, the moveable part making the spring leaf pivot and actuating said second switch when the moveable part reach a certain position.
7. The battery charger as claimed in claim 6, wherein said first switch discriminates between a AAA-type battery or a AA-type battery and a C-type battery, further wherein said second switch discriminates between a C-type battery and a D-type battery.
8. The battery charger as claimed in claim 1, further comprising a second pair of depressible posts actuating a second switch of the at least one switch if a battery larger than the distance between the second pair of depressible posts is inserted in the battery charger, the distance between said first pair of depressible posts and said distance between said second pair of depressible posts being substantially different in order to discriminate at least three types of batteries.
9. The battery charger as claimed in claim 1, further comprising another depressible post located on said support surface, the other depressible post actuating a second switch if a battery is inserted over it, the other depressible post being located at a predetermined distance from said first pair of depressible posts, the predetermined distance enabling to discriminate between two types of batteries, wherein at least three types of batteries may be discriminated.
10. The battery charger as claimed in claim 9 wherein said at least three types of batteries comprise AA-type battery or AAA-type battery, C-type battery and D-type battery.
11. The battery charger as claimed in claim 8, wherein said second pair of depressible posts is provided by a second two-pronged fork, the second two-pronged fork actuating said second switch.
12. The battery charger as claimed in claim 9, wherein said second two-pronged fork moves in a vertical plane to said support surface to actuate said second switch.
13. The battery charger as claimed in claim 12, wherein said second two-pronged fork pivots about a fixed axis, moving rotatively in a substantially vertical plane, to actuate said second switch.
14. The battery charger as claimed in claim 1, wherein a switch of the at least one switch is a tactile switch.
15. The battery charger as claimed in claim 1, wherein a non-moveable conductive element connected to a terminal of the battery extends perpendicularly to the printed circuit board, the conductive element being connected to the printed circuit board by bonding to it in an electrically conductive joint.
16. The battery charger as claimed in claim 15, wherein said non-moveable conductive element connected to a terminal of the battery has an inwardly curved surface in order to center the battery.
