Abstract

The device for adjusting and clamping a strap comprises superposed first and second rings to define a slot for the strap to pass through. The second ring presses on the first ring. The slot for the strap to pass through is bounded by an outer edge of the second ring and an inner edge) of the first ring. The two rings are movable with respect to one another so that the slot for the strap to pass through is of variable thickness. A bottom surface of the first ring opposite the top surface of the first ring has a textured area provided with several salient elements designed to form an increased friction area between the strap and the bottom surface of the first ring. The textured area is separated from the outer edge of the second ring by the slot for the strap to pass through.

First claim

The invention claimed is:

1. Device for adjusting and clamping a strap, comprising a first ring and a second ring superposed to define a slot for the strap to pass through, the second ring pressing on a top surface of the first ring, the slot for the strap to pass through being bounded by an outer edge of the second ring and an inner edge of the first ring,
wherein the first ring and second ring are movable with respect to one another so that the slot for the strap to pass through is of variable thickness and the first and second rings are in a clamping position when the strap is tensioned or they are in a releasing position after a relative movement between the first and second rings causing the thickness of the slot for the strap to pass through to be increased,
wherein a bottom surface of the first ring opposite the top surface of the first ring has a textured area provided with several salient elements designed to form an increased friction area between the strap and the bottom surface of the first ring, the textured area being separated from the outer edge of the second ring by the slot for the strap to pass through, and
wherein the salient elements are formed on a support that is fitted removable with respect to the first ring.

2. Device for adjusting and clamping a strap according to claim 1 , wherein the textured area has salient elements designed to sink into the strap.

3. Device for adjusting and clamping a strap according to claim 2 , wherein the salient elements are located at a first distance from the inner edge, the first distance being not zero and less than twice the thickness of the first ring.

4. Device for adjusting and clamping a strap according to claim 1 , wherein at least a part of the salient elements is formed by gripping spikes.

5. Device for adjusting and clamping a strap according to claim 1 , wherein at least a part of the salient elements is formed in the bulk of the first ring.

6. Device for adjusting and clamping a strap according to claim 1 , wherein at least a part of the salient elements is formed by a material insert moulded on the first ring.

7. Device for adjusting and clamping a strap according to claim 1 , wherein the support at least partially covers the bottom surface of the first ring and forms a hook covering the inner edge and a part of the top surface.

8. Adjustment and clamping system comprising a device for adjusting and clamping a strap according claim 1 and a strap, wherein the height of the salient elements is less than or equal to twice the thickness of the strap.

9. Roping harness comprising an adjustment and clamping system according to claim 8 .
