Abstract

A battery pack for an electric appliance has a base body, a locking element that is movable relative to the base body, is provided for locking the base body to the electric appliance, and has a locked position, and a holding element, which is provided to maintain the locked position when the base body is in the locked state. The holding element is integrally joined to the locking element.

Claims

1. A battery pack for an electrical appliance, comprising a base body;

locking means movable relative to said body for locking said base body to the electrical appliance, said locking means having a locked position;

holding means for maintaining the locked position when said base body is in a locked state, said holding means being integrally joined to said locking means.

2. A battery pack as defined in claim 1, wherein said holding means is constituted by said locking means.

3. A battery pack as defined in claim 1, wherein said locking means is configured as a spring element.

4. A battery pack as defined in claim 3, wherein said locking means is configured as a metallic spring element.

5. A battery pack as defined in claim 1, wherein when said base body is in the locked state, said spring element is prestressed in said locked position.

6. A battery pack as defined in claim 3, wherein said spring element is configured as a flexion spring.

7. A battery pack as defined in claim 3, wherein said spring element has a detent shape.

8. A battery pack as defined in claim 1;

and further comprising an actuating device for actuating said locking means out of the locked position, said locking means engaging in said actuating device.

9. A battery pack as defined in claim 1;

and further comprising an actuating device for actuating said locking means out of the locked position, said actuating device having a sliding surface for a sliding action of said locking means.

10. A battery pack as defined in claim 1;

and further comprising an actuating device for actuating said locking means out of the locked position, said locking means being connected to said actuating device by a form-locked engagement.

11. A battery pack as defined in claim 1, wherein said locking means is fastened to said base body by a form-locked engagement.

12. A battery pack as defined in claim 1;

and further comprising a contiguous surface that constitutes at least one receiving region for receiving an electrical appliance connecting means of the electrical appliance and has an opening in which said locking means is situated in the locked position.

13. An electrical appliance, comprising an electrical appliance base body;

and a battery pack that is detachable from said electrical appliance base body, said battery pack including a base body, locking means movable relative to said body for locking said base body to the electrical appliance, said locking means having a locked position, and holding means for maintaining the locked position when said base body is in a locked state, said holding means being integrally joined to said locking means.
