Abstract

A quad anchor can have a first attachment loop and a second attachment loop. Each of the first and second attachment loops are operable to connect to an anchor point. The quad anchor can also include an intermediate loop disposed between the first attachment loop and the second attachment loop and joined to the first attachment loop and the second attachment loop. The intermediate loop is operable to connect to a load to be supported by the quad anchor.

First claim

What is claimed is:

1. A quad anchor, comprising:
a first attachment loop;
a second attachment loop, each of the first attachment loop and the second attachment loop being configured to connect to an anchor point; and
an intermediate loop disposed between the first attachment loop and the second attachment loop, the intermediate loop being permanently joined to the first attachment loop and the second attachment loop at a first pinch point and a second pinch point, respectively, and the intermediate loop being configured to connect to a load to be supported by the quad anchor;
wherein the first attachment loop, the second attachment loop, and the intermediate loop are formed from a first, single loop of flexible material, wherein portions of the first loop of flexible material are joined together at the first pinch point to form the first attachment loop and at the second pinch point to form the second attachment loop, the intermediate loop being formed between the first pinch point and the second pinch point;
wherein a second loop of flexible material encircles the first loop of flexible material.

2. The quad anchor of claim 1 , wherein the second loop of flexible material defines an outer loop and the first loop of flexible material defines an inner loop, the outer loop being joined to the inner loop at a first connection point disposed at the first attachment loop and at a second connection point disposed at the second attachment loop.

3. The quad anchor of claim 2 , wherein the outer loop is joined to the inner loop at a plurality of third connection points disposed between the first pinch point and the second pinch point.

4. The quad anchor of claim 3 , wherein the first loop is sewn to the second loop at at least one of the plurality of third connection points.

5. The quad anchor of claim 2 , wherein the first connection point is located at a first end of the quad anchor and the second connection point is located at a second end of the quad anchor.

6. The quad anchor of claim 2 , wherein the first loop and the second loop comprise at least one of: nylon; polyethylene; polyester; acrylic; aramid; or ultra-high molecular weight polyethylene.

7. The quad anchor of claim 2 , wherein the first loop and the second loop are each 50 to 140 cm in length.

8. The quad anchor of claim 1 , wherein at least one of the first pinch point and the second pinch point are sewn.

9. The quad anchor of claim 1 , wherein the first pinch point is located 1-6 inches away from a first end of the first loop and the second pinch point is located 1-6 inches away from a second end of the first loop.

10. A quad anchor, comprising:
a first loop of flexible material;
a first attachment loop of flexible material, the first attachment loop being permanently joined to the first loop of flexible material at a first end of the first loop of flexible material;
a second attachment loop of flexible material, the second attachment loop being permanently joined to the first loop of flexible material at a second end of the first loop of flexible material, and
a second loop of flexible material encircling the first loop of flexible material;
wherein the first loop of flexible material is configured to connect to a load between the first attachment loop and the second attachment loop.

11. The quad anchor of claim 10 , wherein the second loop of flexible material is connected to the first loop of flexible material and the first attachment loop at the first end, and wherein the second loop of flexible material is connected to the first loop of flexible material and the second attachment loop at the second end.

12. The quad anchor of claim 10 , further comprising a first spring hook configured to attach the first attachment loop to a first anchor point, a second spring hook configured to attach the second attachment loop to a second anchor point, and a third spring hook configured to attach to the first loop of flexible material between the first attachment loop and the second attachment loop to attach the load to the quad anchor.

13. The quad anchor of claim 1 , wherein the first attachment loop, the second attachment loop, and the intermediate loop are comprised of a flexible material comprising a strength rating of at least 12 kN.

14. The quad anchor of claim 1 , wherein the first attachment loop, the second attachment loop, and the intermediate loop are comprised of an elastic band, a woven rope, or a polymer strand.
