Abstract

A hand-held power tool, in particular a screwdriver, includes an elongate housing, in which is arranged a drive motor for driving an insertion tool, which can be arranged in an associated tool holder. The housing has a grip region, in which is arranged at least one operating element for activating the drive motor. A sliding switch for activating reversing operation of the drive motor is arranged on the housing. In order for the grip region to be formed ergonomically to provide for a first and second possible grip position of the housing, the sliding switch and the operating element are arranged in the vicinity of one another in the longitudinal direction of the housing such that the operating element and the sliding switch can be operated using one finger.

First claim

1 . A hand-held power tool comprising:
an elongate housing including a grip region; a drive motor arranged in the elongate housing and configured to drive an insertion tool; a tool holder configured to receive the insertion tool; at least one operating element arranged in the grip region and configured to activate the drive motor; and a sliding switch arranged on the housing and configured to activate a reversing operation of the drive motor, wherein, in order for the grip region to be formed ergonomically to provide for a first possible grip position and second possible grip position of the housing, the sliding switch and the operating element are arranged in the vicinity of one another in a longitudinal direction of the housing such that the operating element and the sliding switch are operable using one finger.

2 . The hand-held power tool according to claim 1 , wherein the housing is designed such that, in the first possible grip position, a user holds the housing in one hand at an axial end of the housing that is directed away from the tool holder.

3 . The hand-held power tool according to claim 2 , wherein the axial end of the housing directed away from the tool holder is designed such that, in the first possible grip position, the axial end enables the user's hand to grip around the housing in such a way that the user's thumb is oriented in the direction of the tool holder.

4 . The hand-held power tool according to claim 1 , wherein the housing is configured such that, in the second possible grip position, the housing enables a user to hold the housing in one hand along the grip region between the tool holder and an axial end that is directed away from the tool holder.

5 . The hand-held power tool according to claim 4 , wherein the grip region is configured such that, in the second possible grip position, the grip region enables the user's hand to grip around the grip region such that the user's thumb is oriented in the direction of the axial end directed away from the tool holder.

6 . The hand-held power tool according to claim 1 , wherein the at least one operating element and the sliding switch are arranged so as to enable a user to operate both the at least one operating element and the sliding switch using one finger.

7 . The hand-held power tool according to claim 1 , wherein the at least one operating element and the sliding switch are arranged at an axial end of the elongate housing that is directed away from the tool holder.

8 . The hand-held power tool according to claim 1 , wherein the drive motor is activated by contact of the tool holder against a workpiece which is to be machined or by the operating element.

9 . The hand-held power tool according to claim 8 , wherein contact of the tool holder against the workpiece measuring at least 0.1 Nm activates the drive motor.

10 . A method for operating a hand-held power tool that includes (i) an elongate housing including a grip region, (ii) a drive motor arranged in the elongate housing and configured to drive an insertion tool, (iii) a tool holder configured to receive the insertion tool, (iv) at least one operating element arranged in the grip region and configured to activate the drive motor, and (v) a sliding switch arranged on the housing and configured to activate a reversing operation of the drive motor, wherein, in order for the grip region to be formed ergonomically to provide for a first possible grip position and second possible grip position of the housing, the sliding switch and the operating element are arranged in the vicinity of one another in a longitudinal direction of the housing such that the operating element and the sliding switch are operable using one finger the method comprising:
setting a direction of rotation of the drive motor via the sliding switch; and activating the drive motor via the operating element or by contact of the tool holder against a workpiece which is to be machined.

11 . The hand-held power tool according to claim 1 , wherein the hand-held power tool is a screwdriver.

12 . The hand-held power tool according to claim 6 , wherein the at least one operating element and the sliding switch are arranged so as to enable the user to operate both the at least one operating element and the sliding switch using a thumb.

13 . The hand-held power tool according to claim 8 , wherein the contact is an axial contact of the tool holder against the workpiece.

14 . The method according to claim 10 , wherein the hand-held power tool is a screwdriver.
