Abstract

A receiving clamp for a power tool has a clamp body with first and second end faces and a receptacle extending from the first to the second end face. The receptacle is provided to receive a guide rod of the power tool. The receptacle has a longitudinal center axis and a slot extending from the first to the second end face. The slot is open across its entire length relative to the environment. The clamp body has bending elasticity in a direction transverse to the slot so that the slot can be widened. A suspending location is arranged on the clamp body and connectable to a carrying system for the power tool. The suspending location is arranged such that, when the receiving clamp is suspended by the suspending location and the longitudinal center axis is positioned in a horizontal plane, the slot is lower than the suspending location.

First claim

What is claimed is:

1 . A receiving clamp for a power tool, the receiving clamp comprising:
a clamp body comprising a first end face and a second end face and a receptacle extending from the first end face to the second end face and configured to receive a guide rod of a power tool; wherein the receptacle comprises a longitudinal center axis and further comprises a slot extending from the first end face to the second end face; wherein the slot is open relative to an environment across an entire length of the slot from the first end face to the second end face; wherein the clamp body comprises a bending elasticity in a direction transverse to a length direction of the slot so that the slot can be widened; at least one suspending location arranged on the clamp body and configured to connect to a carrying system for the power tool; wherein the at least one suspending location is arranged such that, when the receiving clamp is suspended by the at least one suspending location and the longitudinal center axis is positioned in a horizontal plane, the slot is located lower than the at least one suspending location.

2 . The receiving clamp according to claim 1 , wherein the bending elasticity counteracts widening of the slot.

3 . The receiving clamp according to claim 1 , further comprising insertion elements configured to thread a guide of the power tool into the receptacle, wherein the insertion elements are arranged so as to extend at least partially along the slot.

4 . The receiving clamp according to claim 3 , wherein the insertion elements each have a support edge extending parallel to the longitudinal center axis and configured to support the receiving clamp on a support surface.

5 . The receiving clamp according to claim 1 , wherein the receptacle has a length measured parallel to the longitudinal center axis and has a smallest inner diameter measured perpendicular to the longitudinal center axis, wherein the length is greater than the smallest inner diameter.

6 . The receiving clamp according to claim 1 , further comprising clamping ribs arranged on an inner surface of the receptacle and extending in a circumferential direction of the receptacle.

7 . The receiving clamp according to claim 1 , wherein the clamp body comprises two rigid receiving elements and at least one spring element.

8 . The receiving clamp according to claim 7 , wherein the two receiving elements are connected by a joint to each other.

9 . The receiving clamp according to claim 7 , wherein the two receiving elements are braced relative to each other by the at least one spring element.

10 . The receiving clamp according to claim 7 , wherein the at least one spring element extends about a wrap angle of at least 200° measured about the longitudinal center axis.

11 . The receiving clamp according to claim 7 , wherein the receptacle has a smallest inner diameter measured perpendicular to the longitudinal center axis, wherein a spacing of the at least one spring element measured in a direction of the longitudinal center axis relative to the at least one suspending location is at least 0.5 times the smallest inner diameter.

12 . An arrangement comprising:
a carrying system for a power tool; a receiving clamp comprising a clamp body comprising a first end face and a second end face and a receptacle extending from the first end face to the second end face, wherein the receptacle comprises a longitudinal center axis and further comprises a slot extending from the first end face to the second end face, wherein the slot is open relative to the environment across an entire length of the slot from the first end face to the second end face, wherein the clamp body comprises a bending elasticity in a direction transverse to a length direction of the slot so that the slot can be widened, wherein at least one suspending location is arranged on the clamp body and configured to connect to the carrying system, wherein the at least one suspending location is arranged such that, when the receiving clamp is suspended by the at least one suspending location and the longitudinal center axis is positioned in a horizontal plane, the slot is located lower than the at least one suspending location; wherein the carrying system comprises a support arm and the receiving clamp is arranged on the support arm; wherein the receiving clamp is held by the at least one suspending location on the carrying system, wherein the slot is at least partially facing downwardly in an operating position of the carrying system, wherein in the operating position the receiving clamp is suspended from the carrying system.

13 . An arrangement comprising:
a power tool comprising a guide rod; a carrying system configured to carry the power tool; a receiving clamp comprising a clamp body comprising a first end face and a second end face and a receptacle extending from the first end face to the second end face, wherein the receptacle comprises a longitudinal center axis and further comprises a slot extending from the first end face to the second end face, wherein the slot is open relative to the environment across an entire length of the slot from the first end face to the second end face, wherein the clamp body comprises a bending elasticity in a direction transverse to a length direction of the slot so that the slot can be widened, wherein at least one suspending location is arranged on the clamp body and configured to connect to the carrying system, wherein the at least one suspending location is arranged such that, when the receiving clamp is suspended by the at least one suspending location and the longitudinal center axis is positioned in a horizontal plane, the slot is located lower than the at least one suspending location; wherein the guide rod of the power tool is secured in the receptacle; wherein the slot is at least partially facing downwardly in an operating position of the guide rod, wherein in the operating position the power tool is suspended from the carrying system and secured by the receiving clamp on the carrying system.

14 . The arrangement according to claim 13 , wherein the guide rod is clamped in the receiving clamp by a spring force.

15 . The arrangement according to claim 14 , wherein the receiving clamp comprises an actuating device, wherein by actuating the actuating device the spring force is at least partially canceled and the guide rod of the power tool is slidable in the direction of the longitudinal center axis in the receiving clamp.

16 . The arrangement according to claim 13 , wherein the bending elasticity of the receiving clamp counteracts widening of the slot and wherein widening the slot requires an opening force in a direction from the at least one suspending location toward the slot of at least 1.5 times a weight force of the power tool.

17 . The arrangement according to claim 16 , wherein the slot is configured to be widened by a release force acting on the guide rod at least partially in a direction of the force of gravity such that the guide rod is removable through the slot from the receiving clamp by the release force.
