Abstract

A battery pack for an electric appliance has a base body, a locking unit for locking the base body to the electric appliance, an actuating element for unlocking the base body, which element is intended to be actuated by a user in an actuating direction, and a removal direction in which it is possible to remove the base body after it has been unlocked from the electric appliance. The actuating direction has at least one component oriented counter to the removal direction.

Claims

1. A battery pack for an electrical appliance, comprising:

a base body;

a locking unit for locking said base body to the electrical appliance; and

an actuating element pivotably coupled to the base body for unlocking said base body, said actuating element being actuatable by a user in an actuating direction having at least one component that is oriented counter to a removal direction for removing the base body from the electrical appliance after unlocking the base body from the electrical appliance.

2. A battery pack as defined in claim 1, wherein said actuating element is configured so that the actuating direction is oriented counter to the removal direction.

3. A battery pack as defined in claim 1, wherein said actuating element is configured as a pushbutton.

4. A battery pack as defined in claim 1, wherein said base body has a removal side, said actuating element being situated on said removal side of said base body.

5. A battery pack as defined in claim 1;

and further comprising guiding means for guiding said base body in the removal direction, said guiding means being provided for supporting said base body on the electrical appliance perpendicular to the removal direction, at least during a removal process.

6. A battery pack as defined in claim 5, wherein said guide means is configured as a guide rail that extends in the removal direction.

7. An electrical appliance, comprising:

an electrical appliance base body; and

a battery pack that is detachable from said electrical appliance base body, said pack including a base body, a locking unit for locking said base body to the electrical appliance, an actuating element pivotably coupled to the base body for unlocking said base body, said actuating element being actuated by a user in an actuating direction having at least one component that is oriented counter to a removal direction for removing the base body from the electrical appliance after unlocking the base body from the electrical appliance.
