Abstract

A hand-held power tool device, in particular a hammer drill and/or chisel hammer device, includes at least one operating element and at least one locking unit. The at least one locking unit includes at least one locking element and at least one controllable actuator element. The at least one locking element can be moved from at least one storage position into at least one locking position, and vice versa, and locks the operating element in at least one operating state in the locking position. The at least one controllable actuator element influences motion of the locking element.

Claims (27)

1. A hand-held power tool device, comprising:

at least one operator-control element; and

at least one locking unit including:

at least one locking element configured to be moved from at least one storage position into at least one locking position, and from the at least one locking position into the at least one storage position; and

at least one actuator element configured to be activated and to move the at least one locking element from the at least one storage position to the at least one locking position,

wherein, the at least one actuator element is configured to be activated electrically, and in the at least one locking position, in at least one operating state, the at least one locking element locks the at least one operator-control element.

2. The hand-held power tool device as claimed in claim 1 , wherein:

the at least one operator-control element defines at least one holding recess; and

the at least one locking element engages the at least one holding recess in the at least one operating state.

3. The hand-held power tool device as claimed in claim 1 , wherein:

the at least one actuator element includes at least one electromagnet; and

the at least one locking element is configured to be at least partly magnetic.

4. The hand-held power tool device as claimed in claim 1 , wherein the at least one actuator element and the at least one locking element are part of a stroke magnet.

5. The hand-held power tool device as claimed in claim 1 , wherein the at least one actuator element is configured, at least partly, to be variable in shape.

6. The hand-held power tool device as claimed in claim 1 , further comprising:

at least one further operator-control element including at least three operator-control positions.

7. The hand-held power tool device as claimed in claim 1 , further comprising:

at least one locking switch which, upon being actuated, initiates a locking.

8. The hand-held power tool device as claimed in claim 7 , further comprising:

a control unit configured to take account of at least one actuation and/or operator-control position of the at least one locking switch so as to activate the at least one actuator element.

9. The hand-held power tool device as claimed in claim 1 , wherein the hand-held power tool device is a hammer drill and/or chipping hammer device.

10. A hand-held power tool device, comprising:

at least one operator-control element; and

at least one locking unit including:

at least one locking element configured to be at least partly magnetic and configured to be moved with respect to the at least one operator-control element from at least one storage position into at least one locking position, and from the at least one locking position into the at least one storage position; and

at least one actuator element including at least one electromagnet and configured to be activated and to influence the movement of the at least one locking element,

wherein, in the at least one locking position, in at least one operating state, the at least one locking element locks the at least one operator-control element.
