Abstract

A hand-held tool that is prepared for remote control has a handle region, an actuating button, and a removable attachment part held in the handle region. The attachment part has a handling extension and a collar encompassing the handle region. The collar includes first and second collar parts pivotably connected together. The attachment part acts upon the actuating button. The actuating button is displaced into an actuating position by a housing section of the collar for a duration of an arrangement of the attachment part on the handle region.

First claim

The invention claimed is:

1. A hand tool that is prepared for remote control comprising:
a handle region;
an actuating button; and
an attachment part which is configured to be removably attached to the handle region, the attachment part including first and second collar parts pivotably connected together and configured to surround the handle region, wherein at least one of the collar parts forming a housing section, wherein the actuating button is displaced into an actuating position by engagement with the housing section when the collar parts surround the handle region; and
a handling extension coupled to the attachment part.

2. The hand tool according to claim 1 , wherein the handling extension is pivotally coupled to the attachment part, wherein the handling extension can be positioned in different angular orientations relative to a longitudinal axis of the attachment part.

3. The hand tool according to claim 1 , further comprising a radio receiver and a control unit configured to convert received radio signals into an initiation of a working motion of the hand tool.

4. The hand tool according to claim 1 , wherein the handling extension includes an actuating element configured to initiate a working motion of the hand tool remotely.

5. The hand tool according to claim 4 , wherein the handling extension includes a radio transmitter operatively connected to the actuating element and which interacts with the radio receiver.

6. The hand tool according to claim 1 , wherein each collar part is shaped as a half shell.

7. The hand tool according to claim 6 , further comprising a lock configured to mechanically lock the collar parts together around the handle region.

8. The hand tool according to claim 1 , wherein the attachment part includes a holding formation provided thereon which is configured to connect to the handling extension.

9. The hand tool according to claim 8 , wherein the holding formation comprises a plurality of projections configured to engage into depressions in the handling extension.

10. The hand tool according to claim 8 , wherein the holding formation comprises a plurality of depressions configured to receive projections on the handling extension.

11. The hand tool according to claim 1 , further comprising an electric motor which is actuable to carry out a working motion.

12. The hand tool according to claim 11 , wherein the electric motor drives a hydraulic pump configured to act upon a hydraulically actuated working piston.

13. The hand tool according to claim 1 , further comprising one or more working jaws coupled to the handle region which can be moved from a release position into a working position and from the working position into the release position.

14. The hand tool according to claim 13 , wherein the one or more working jaws are moved from the working position into the release position after an expiration of a predefined time period.

15. The hand tool according to claim 1 , wherein a current-conducting connection produced as a result of a depression of the actuating button is without a motion of the actuating button interrupted after an expiration of a predefined time period.

16. The hand tool according to claim 1 , further comprising a lock configured to mechanically lock the collar parts together around the handle region.

17. A hand tool that is prepared for remote control comprising:
a handle region;
an actuating button on the handle region;
a housing tang extending from the handle region; and
a removable attachment part including two collar parts pivotably connected at a pivot joint region, wherein the collar parts are configured to be attached to the handle region with the housing tang extending through an opening provided in the pivot joint region; and
a handling extension coupled to the attachment part.

18. The hand tool according to claim 17 , wherein the attachment part is configured to act upon the actuating button to actuate the hand tool.

19. The hand tool according to claim 17 , further comprising a radio receiver and a control unit configured to convert received radio signals into an initiation of a working motion of the hand tool.
