Abstract

A tool for crimping, pressing or deforming a workpiece includes a first grip element having a first grip portion; a second grip element having a second grip portion; a mechanism housing, which is arranged on the first grip element and has an end surface facing away from the first grip portion; a tool mechanism, which is enclosed by the mechanism housing and can be actuated to crimp, press or deform the workpiece by adjusting the first and second grip elements relative to one another; and an impact protection element, which is arranged on the first grip demerit and has two limbs and an end face portion, which interconnects the limbs. The mechanism housing is arranged between the limbs, and the end face portion extends beyond the end surface of the mechanism housing.

First claim

The invention claimed is:

1. A tool for crimping, pressing or deforming a workpiece, comprising:
a first grip element having a first grip portion;
a second grip element having a second grip portion;
a mechanism housing, which is arranged on the first grip element and has an end surface facing away from the first grip portion;
a tool mechanism, which is enclosed by the mechanism housing and is connected to the second grip element so as to be actuable to crimp, press, or deform the workpiece by pivoting the first and second grip elements relative to one another about a pivot axis passing perpendicularly through the tool mechanism; and
an impact protection element, which is arranged on the first grip element and has two limbs and an end face portion, which interconnects the limbs,
wherein the mechanism housing is arranged between the limbs, and the end face portion extends beyond the end surface of the mechanism housing.

2. The tool according to claim 1 , wherein the impact protection element is U-shaped.

3. The tool according to claim 1 ,
wherein the end face portion extends parallel to the pivot axis beyond the end surface of the mechanism housing.

4. The tool according to claim 3 , wherein the limbs of the impact protection element extend along opposing side surfaces of the mechanism housing, which are spaced apart from one another along the pivot axis.

5. The tool according to claim 3 , wherein the end surface of the mechanism housing includes a portion that is curved in the form of a circular arc about the pivot axis.

6. The tool according to claim 1 , wherein the end face portion of the impact protection element has a first impact edge, which is arranged with respect to a second impact edge of the first grip element in such a way that the mechanism housing is set back in relation to an imaginary line interconnecting the first impact edge and the second impact edge.

7. The tool according to claim 1 , wherein the first grip element is comprised of plastics material.

8. The tool according to claim 1 , wherein the impact protection element together with the first grip element are comprised of plastics material.

9. The tool according to claim 1 , wherein the mechanism housing is comprised of metal.

10. The tool according to claim 1 , wherein at least one of the limbs has an opening configured to introduce the workpiece into a working space of the tool mechanism.

11. The tool according to claim 10 , wherein the opening comprises a lead-in chamfer.

12. The tool according to claim 1 , wherein the tool mechanism has an adjusting element and at least one pressing element movably arranged on the adjusting element,
wherein the adjusting element is pivotably mounted in the mechanism housing, and
wherein the adjusting element is configured to be actuated to move the pressing element by adjusting the first and second grip elements relative to one another.

13. The tool according to claim 12 , wherein the at least one pressing element is configured to be moved to crimp, press, or deform the workpiece by pivoting the adjusting element.

14. The tool according to claim 1 , wherein the end face portion of the impact protection element has a first impact edge, which is arranged with respect to a second impact edge of the second grip element in such a way that the mechanism housing is set back in relation to an imaginary line interconnecting the first impact edge and the second impact edge.
