Abstract

In a hand-held power tool with a device for presetting a selected rotation direction of a drive motor that is associated with the power tool and contained in a tool housing. The device is equipped with an actuating element accessible from outside the tool housing for mechanically actuating a switch element, which is situated inside the tool housing and is at least embodied for electrically switching between a first and second rotation direction of the drive motor, the switch element is situated in the vicinity of the actuating element.

First claim

We claim:

1. A hand-held power tool with a device for presetting a selected rotation direction of a drive motor that is associated with the power tool and contained in a tool housing, the device comprising
an actuating element accessible from outside the tool housing, the tool housing having at least a first opening through which a first axial end region of the actuating element protrudes and a second opening through which a second axial end region of the actuating element protrudes,
which actuating element is linearly slidable in a transverse direction relative to the longitudinal span of the power tool for mechanically actuating a slider that is associated with a switch element,
which switch element is situated inside the tool housing and is at least embodied for electrically switching between a first and second rotation direction of the drive motor,
wherein the actuating element has a central recess or opening in which the switch element is at least partially accommodated,
wherein the actuating element has a holding element which protrudes into the central recess or opening and is configured to releasably connect the slider such that the slider is at least partially accommodated in the central recess or opening.

2. The power tool as recited in claim 1 , wherein the central recess or opening is embodied to trigger a switching of the switch element when the actuating element is actuated.

3. The power tool as recited in claim 2 , wherein the slider is adapted from the switching and is at least partially accommodated in the central recess or opening.

4. The power tool as recited in claim 3 , wherein the slider is detachably fastened to the holding element embodied on the central recess or opening.

5. The power tool as recited in claim 4 , wherein the holding element has at least one first rib-like protrusion and one second rib-like protrusion and the slider is at least partially accommodated between the first and second protrusions.

6. The power tool as recited in claim 3 , wherein the switch element is fastened to a circuit board provided in the tool housing.

7. The power tool as recited in claim 1 , wherein the slider is adapted for the switching and is at least partially accommodated in the central recess or opening.

8. The power tool as recited in claim 7 , wherein the slider is detachably fastened to the holding element embodied on the central recess or opening.

9. The power tool as recited in claim 8 , wherein the holding element has at least one first rib-like protrusion and one second rib-like protrusion and the slider is at least partially accommodated between the first and second protrusions.

10. The power tool as recited in claim 7 , wherein the switch element is fastened to a circuit board provided in the tool housing.

11. The power tool as recited in claim 7 , wherein the actuating element has a blocking element that is embodied to prevent the actuating element from being actuated during operation of the power tool.

12. The power tool as recited in claim 11 , further comprising a manual switch for switching the drive motor on and off, the manual switch provided with a stop element that is embodied to block the blocking element in a selected preset rotation direction during operation of the power tool.

13. The power tool as recited in claim 1 , wherein the switch element is fastened to a circuit board provided in the tool housing.

14. The power tool as recited in claim 1 , wherein the actuating element has a blocking element that is embodied to prevent the actuating element from being actuated during operation of the power tool.

15. The power tool as recited in claim 14 , further comprising a manual switch for switching the drive motor on and off, the manual switch provided with a stop element that is embodied to block the blocking element in a selected preset rotation direction during operation of the power tool.

16. The power tool as recited in claim 1 , wherein the device is supported on the tool housing.
