Abstract

A battery-operated screwdriver has a housing with a handle, a rechargeable battery, charge contacts for charging the battery on a charger shell having at least one detachably mounted bit holder for storing tool inserts of the battery-operated screwdriver in captive fashion, so that the battery-operated screwdriver is placeable on the charger shell and a charging mode is produced automatically, and a charger shell for a battery-operated screwdriver has at least one detachable mountable bit holder configured to receive a plurality of bits which in operation are insertable in communication with the battery-operated screwdriver.

Claims

1. A charger shell for a battery-operated screwdriver, comprising:

at least one detachably mountable bit holder that is configured to receive a plurality of bits, which in operation can be inserted in communication with a battery-operated screwdriver;

wherein the bit holder has a plurality of insertion openings for receiving the plurality of bits.

2. The charger shell of claim 1, wherein the bit holder is received in the charger shell in an overlockable fashion.

3. The charger shell of claim 1, wherein the charger shell has a groove-like indentation configured to receive the bit holder.

4. The charger shell of claim 3, wherein the indentation is slightly narrower than the bit holder.

5. The charger shell of claim 1, wherein the bit holder is made of an elastic material.

6. A charger shell for a battery-operated screwdriver, comprising:

at least one detachably mountable bit holder that is configured to receive a plurality of bits, which in operation can be inserted in communication with a battery-operated screwdriver;

wherein the bit holder has a plurality of insertion openings for receiving the plurality of bits

wherein the charger shell has a groove-like indentation configured to receive the bit holder, and

wherein the indentation is longer than the bit holder such that when the bit holder is inserted into the indentation, the indentation remains free in a residual region for removing the bit holder using a finger.

7. A charger shell for a battery-operated screwdriver, comprising:

at least one detachably mountable bit holder that is configured to receive a plurality of bits, which in operation can be inserted in communication with a battery-operated screwdriver;

wherein the bit holder has a plurality of insertion openings for receiving the plurality of bits, and

wherein the charger shell has an outer contour which corresponds to a triangle standing on its base when viewed from the side.

8. The charger shell of claim 7, wherein oblique faces of the charger shell are adapted to a pistol-shaped contour of the battery-operated screwdriver.

9. The charger shell of claim 7, wherein the charger shell has an embedding arrangement which is subdivided into a handle bed and a gearbox bed.

10. The charger shell of claim 7, wherein charge contacts protrude upwardly out of a contour of the embedding arrangement.

11. A charger shell for a battery-operated power tool, comprising:

at least one detachably mountable bit holder that is configured to receive a plurality of bits, which in operation can be inserted in communication with a battery-operated powertool;

wherein the bit holder has a plurality of insertion openings for receiving the plurality of bits.

12. The charger shell of claim 11, wherein the bit holder is received in the charger shell in an overlockable fashion.

13. The charger shell of claim 11, wherein the charger shell has a groove-like indentation configured to receive the bit holder.

14. The charger shell of claim 13, wherein the indentation is slightly narrower than the bit holder.

15. The charger shell of claim 11, wherein the bit holder is made of an elastic material.

16. The charger shell of claim 11, wherein the powertool is a power drill.

17. A charger shell for a battery-operated power tool, comprising:

at least one detachably mountable bit holder that is configured to receive a plurality of bits, which in operation can be inserted in communication with a battery-operated powertool;

wherein the bit holder has a plurality of insertion openings for receiving the plurality of bits,

wherein the charger shell has a groove-like indentation configured to receive the bit holder, and

wherein the indentation is longer than the bit holder such that when the bit holder is inserted into the indentation, the indentation remains free in a residual region for removing the bit holder using a finger.

18. The charger shell of claim 17, wherein the powertool is a power drill.

19. A charger shell for a battery-operated power tool, comprising:

at least one detachably mountable bit holder that is configured to receive a plurality of bits, which in operation can be inserted in communication with a battery-operated powertool;

wherein the bit holder has a plurality of insertion openings for receiving the plurality of bits, and

wherein the charger shell has an outer contour which corresponds to a triangle standing on its base when viewed from the side.

20. The charger shell of claim 19, wherein oblique faces of the charger shell are adapted to a pistol-shaped contour of the battery-operated powertool.

21. The charger shell of claim 19, wherein the charger shell has an embedding arrangement which is subdivided into a handle bed and a gearbox bed.

22. The charger shell of claim 21, wherein charge contacts protrude upwardly out of a contour of the embedding arrangement.
