Abstract

The invention relates to a clamp comprising a clamp band having a clamping head with two clamping jaws, in each of which a guide-through opening is formed, through which a clamping element for clamping the clamp is guided, wherein at least one contact surface is formed on a respective edge of the guide-through openings, on which contact surface a support surface of the clamping element can at least partially be contacted. In order to achieve minimum inner tensions in the clip, the clamping jaws are arranged at an angle to one another, wherein at least one reinforcing bead is formed in the clamping jaws and one of the clamping jaws has an anti-rotation means for the clamping element.

First claim

The invention claimed is:

1. A clamp comprising:
a clamp band;
a clamping head with two clamping jaws; and
a feed-through opening, through which a clamping element is fed for tensioning the clamp, the feed-through opening being formed in each of said clamping jaws;
wherein at least one contact surface is formed on an edge of the feed-through opening on a first of said clamping jaws, the at least one contact surface is configured to receive at least a part of a support surface of the clamping element, the two clamping jaws are arranged at an angle with respect to one another, at least one reinforcing bead is formed in each of the two clamping jaws, a second of said clamping jaws comprises an anti-rotation device for the clamping element, the at least one reinforcing bead formed in each of the clamping jaws extends along center lines of the two clamping jaws, and the center line runs perpendicularly to the clamping element and to an axis of symmetry of the clamp band.

2. The clamp as claimed in claim 1 , wherein the clamping element comprises a screw bolt with a nut, and the screw bolt comprises an external thread with a friction-reducing coating.

3. The clamp as claimed in claim 2 , wherein the clamping jaws are inclined at the angle with respect to one another in such a manner that, during a tensioning operation, the clamping jaws first contact one another in part and, when clamped further, the clamping jaws bear against one another.

4. The clamp as claimed claim 3 , wherein the angle between the clamping jaws is more than 0° and up to 10°.

5. The clamp as claimed in claim 4 , wherein one of the two clamping jaws comprises at least one deformable lug, wherein the at least one deformable lug is directed to another of the two clamping jaws.

6. The clamp as claimed in claim 5 , wherein the at least one deformable lug is formed in one piece with the one of the two clamping jaws.

7. The clamp as claimed in claim 5 , wherein the at least one deformable lug is an element which is held on the clamping jaw with the clamping element.

8. The clamp as claimed in claim 7 , wherein the anti-rotation device is formed by the element.

9. The clamp as claimed in claim 8 , wherein at least one deformable lug is arranged on each of both clamping jaws.

10. The clamp as claimed in claim 9 , wherein at least one of the contact surfaces comprises a friction-reducing coating.

11. The clamp as claimed in claim 10 , wherein the at least one contact surface is raised, and the at least one contact surface is smaller than the support surface of the clamping element.

12. The clamp as claimed in claim 11 , wherein the at least one contact surface has the form of two diametrically opposite circle segments.

13. The clamp as claimed in claim 12 , wherein the at least one contact surface is arranged in the region of the at least one reinforcing bead which is formed in each of the two clamping jaws.

14. The clamp as claimed in claim 13 , wherein the clamp is a profile clamp, the clamp band includes a base and two radially inwardly directed flanks, and the clamp band comprises a trapezoidal or triangular cross section.

15. The clamp as claimed in claim 14 , wherein at least one recess is formed in at least one position in at least one of the flanks.
