Abstract

A rechargeable battery pack interface device includes: at least one connecting unit that is designed to detachably mechanically connect a rechargeable battery pack to a consumer, the mechanical connection being detachable using a relative movement of the rechargeable battery pack relative to the consumer; and a retaining unit that is designed in such a way that, in a non-activated state of the retaining unit, the mechanical connection is detachable using the relative movement of the rechargeable battery pack with respect to the consumer and, in an activated state of the retaining unit, the mechanical connection is detachable using another relative movement which differs from the relative movement.

First claim

What is claimed is:

1. A rechargeable battery pack interface device comprising:
at least one connecting unit via which a rechargeable battery pack is mechanically connectable to a consumer; and
a retaining unit, wherein:
in a non-activated state of the retaining unit, the mechanical connection is severable by a first movement of the rechargeable battery pack relative to the consumer; and
in an activated state of the retaining unit, the mechanical connection is severable by a second movement of the rechargeable battery pack relative to the consumer, wherein the second movement is different from the first movement.

2. The rechargeable battery pack interface device of claim 1 , wherein the first movement is translatory and/or rotatory.

3. The rechargeable battery pack interface device of claim 1 , wherein the first movement has a single freedom of movement.

4. The rechargeable battery pack interface device of claim 1 , wherein the second movement is translatory and/or rotatory.

5. The rechargeable battery pack interface device of claim 1 , wherein the connecting unit includes a movably mounted retaining element.

6. The rechargeable battery pack interface device of claim 5 , wherein the retaining element is mounted pivotably about a pivot axis that extends in a direction of the first movement.

7. The rechargeable battery pack interface device of claim 5 , wherein the retaining unit includes a restoring element that applies a force onto the retaining element.

8. The rechargeable battery pack interface device of claim 5 , wherein the retaining unit includes a restoring element that applies a force onto the retaining element by which the retaining element is retained in the non-activated state.

9. The rechargeable battery pack interface device of claim 8 , wherein the restoring element is a detent ball.

10. The rechargeable battery pack interface device of claim 8 , wherein the restoring element is a leg spring.

11. The rechargeable battery pack interface device of claim 5 , wherein the retaining element is designed as a guide rail.

12. The rechargeable battery pack interface device of claim 1 , wherein the connecting unit includes a movably mounted retaining element, which is a guide rail.

13. A rechargeable battery pack comprising a rechargeable battery pack interface device, the rechargeable battery pack interface device including:
at least one connecting unit via which the rechargeable battery pack is mechanically connectable to a consumer; and
a retaining unit, wherein:
in a non-activated state of the retaining unit, the mechanical connection is severable by a first movement, which is of the rechargeable battery pack relative to the consumer; and
in an activated state of the retaining unit, the mechanical connection is severable by a second movement of the rechargeable battery pack relative to the consumer, wherein the second movement is different from the first movement.

14. The rechargeable battery pack of claim 13 , wherein the rechargeable battery pack is configured for a hand-held power tool.

15. A hand-held power tool comprising:
a body;
rechargeable battery pack;
an adapter situated between the rechargeable battery pack and the body; and
a rechargeable battery pack interface device that includes:
at least one connecting unit via which the rechargeable battery pack is mechanically connectable to a consumer; and
a retaining unit, wherein:
in a non-activated state of the retaining unit, the mechanical connection is severable by a first movement, which is of the rechargeable battery pack relative to the consumer; and
in an activated state of the retaining unit, the mechanical connection is severable by a second movement of the rechargeable battery pack relative to the consumer, wherein the second movement is different from the first movement.
