Abstract

A handle for an electric hand tool, which in use, is detachably connected to the hand tool as an auxiliary handle (2), includes at least one detection device (6), which communicates with at least one regulating and/or control element in the electric hand tool through a contactless signal transmission device.

Claims

1. A handle for an electric hand tool, wherein the handle, in use, is detachably connectable to the electric hand tool as an auxiliary handle and comprises at least one detection device that communicates with at least one element selected from the group consisting of a regulating element and a control element in the electric hand tool by a contactless signal transmission device.

2. The handle according to claim 1, wherein the at least one detection device (6) is a sensor selected from the group consisting of a contact sensor and a force sensor.

3. The handle according to claim 1, wherein the at least one detection device (6) is in acceleration sensor (10).

4. The handle according to claim 1, wherein the at least one detection device (6) is a torque sensor (20).

5. The handle according to claim 1, wherein the at least one detection device (6) is associated with an infrared signal transmitting device.

6. The handle according to claim 1, wherein the at least one detection device (6) is associated with a radio signal transmitting device.

7. The handle according to claim 1, wherein the at least one detection device (6) is associated with a contactless inductive signal transmitting device.

8. The handle according to claim 1, wherein the at least one detection device (6) is associated with a contactless capacitive signal transmitting device.

9. An electric tool with a handle according to claim 1.

10. An electric hand tool, comprising at least one element selected from the group consisting of a regulating control element and a control element and located inside the electric hand tool;

and a handle detachably connectable to the electric hand fool as an auxiliary handle, said handle including at least one detection device that communicates with the at least one element inside the electric hand tool by a contactless signal transmission device.
