Abstract

A hand tool accumulator charging device is proposed having a charging device housing and a charging coil, provided for the purpose of charging a hand tool accumulator situated in an accumulator charging region, and having only one mounting device that is provided for the purpose of coupling with a hand tool case situated in a case receptacle region, the accumulator charging region and the case receptacle region being situated on sides of the charging device housing facing away from one another.

Claims

1. A hand tool accumulator charging device, comprising:

a charging device housing having an accumulator charging region and a case receptacle region for receiving a hand tool case;

a charging coil for charging a hand tool accumulator situated in the accumulator charging region, the charging coil being disposed in the charging device housing; and

one mounting device for coupling with a hand tool case situated in the case receptacle region, the mounting device being disposed on the charging device housing;

wherein the case receptacle region is located on a side of the charging device housing that is different from, and faces away from, a side of the charging device housing at which the accumulator charging region is located,

wherein the accumulator charging region is external to the hand tool case.

2. The hand tool accumulator charging device of claim 1, wherein the charging device housing limits the accumulator charging region with a surface that is essentially planar.

3. The hand tool accumulator charging device of claim 2, wherein the mounting device is configured so as to be releasable by an operator without the use of tools.

4. The hand tool accumulator charging device of claim 1, wherein the mounting device is configured so as to be releasable by an operator without the use of tools.

5. The hand tool accumulator charging device of claim 1, wherein the mounting device has at least one mounting arrangement that is provided for the purpose of locking the hand tool case.

6. The hand tool accumulator charging device of claim 1, wherein the mounting device has two mounting arrangements that are situated on two sides of the case receptacle region situated opposite one another.

7. The hand tool accumulator charging device of claim 1, further comprising:

a charging electronics system for at least controlling a charging process.

8. The hand tool accumulator charging device of claim 1, further comprising:

at least one additional charging coil.

9. The hand tool accumulator charging device of claim 1, wherein a main plane of extension of the charging device housing is oriented essentially perpendicular to a direction of action of the charging coil.

10. The hand tool accumulator charging device of claim 1, wherein the charging device housing is configured to mechanically connect at least the charging coil and the mounting device.

11. The hand tool accumulator charging device of claim 1, wherein the charging device housing encloses an interior space which includes the charging coil and a charging electronics arrangement.

12. The hand tool accumulator charging device of claim 1, wherein the charging device housing delimits the accumulator charging region at least on one side.

13. The hand tool accumulator charging device of claim 1, wherein the charging device housing delimits the case receptacle region at least on one side.

14. The hand tool accumulator charging device of claim 1, wherein the charging device housing is embodied as a substantially flat housing having a main plane of extension, the side at which the case receptacle region is located and the side at which the accumulator charging region is located being arranged substantially parallel to one another along the main plane of extension.

15. The hand tool accumulator charging device of claim 1, wherein the side of the charging device housing at which the case receptacle region is located and the side of the charging device housing at which the accumulator charging region is located are arranged opposite to one another on the charging device housing.

16. The hand tool accumulator charging device of claim 1, wherein the mounting device includes a mounting arrangement having a locking element configured to lock the hand tool case releasably.

17. The hand tool accumulator charging device of claim 16, wherein the mounting device includes an operating element for manually operating the mounting arrangement.

18. A system, comprising:

a hand tool case; and

a hand tool accumulator charging device, including;

a charging device housing having an accumulator charging region and a case receptacle region for receiving the hand tool case;

a charging coil for charging a hand tool accumulator situated in an accumulator charging region, the charging coil being disposed in the charging device housing; and

one mounting device for coupling with a hand tool case situated in the case receptacle region, the mounting device being disposed on the charging device housing, the accumulator charging region and the case receptacle region being situated on sides of the charging device housing facing away from one another and which are different from one another,

wherein the accumulator charging region is external to the hand tool case.

19. The system of claim 18, wherein the hand tool case includes a base body and a case cover, the base body and the case cover being configured to delimit a receptacle space for at least one hand tool.

20. A system, comprising:

a hand tool accumulator; and

a hand tool accumulator charging device, including;

a charging device housing having an accumulator charging region and a case receptacle region for receiving a hand tool case;

a charging coil for charging the hand tool accumulator situated in an accumulator charging region, the charging coil being disposed in the charging device housing; and

one mounting device for coupling with the hand tool case situated in the case receptacle region, the mounting device being disposed on the charging device housing, the accumulator charging region and the case receptacle region being situated on sides of the charging device housing facing away from one another and which are different from one another,

wherein the accumulator charging region is external to the hand tool case.

21. The system of claim 20, wherein the hand tool accumulator is configured to be releasably connected to a hand tool and supply power to the hand tool.
