Abstract

The knot protector protects ropes and knots from ledges, rocks, railings, edges, walls, cliffs, and other surfaces that may cause the fibers of the rope to be gradually abraded or destroyed. The knot protector includes a sleeve formed from an upper portion, a lower portion, and a shoulder portion. The upper portion defines a first opening while the lower portion defines a second opening. The diameter of the first opening is smaller or less than that of the second opening. The sleeve is formed from a deformable, continuous web and has exterior and interior layers. The sleeve also contains visual safety indicators along the base of the lower portion to provide visibility. The exterior and interior layers are made from durable material to provide the rope with ample protection from abrasion.

Claims (26)

1. A knot protector comprising:

a sleeve formed from a deformable, continuous web and defining upper and lower portions with a plurality of material layers defined as an exterior layer further defined as a 1000 denier nylon material and an interior layer further defined as a 1000 denier nylon material and/or a 1680 denier nylon material;

wherein the interior and exterior layers each define a herringbone nylon weave material, with the herringbone nylon weave material of the exterior layer formed from a 0.25 inch thick nylon webbing;

wherein the upper portion defines a first opening and the lower portion defines a second opening, and wherein the first opening defines a diameter that is smaller than a diameter defined by the second opening; and

wherein the knot protector is configured to receive a knot from a rope situated within the upper portion.

2. The knot protector of claim 1 , wherein the sleeve includes one or more receptacle loops.

3. The knot protector of claim 2 , wherein the one or more receptacle loops are positioned on the lower portion.

4. The knot protector of claim 1 , wherein the lower portion includes a first receptacle loop located along a top section of the lower portion and a second receptacle loop located along a base section of the lower portion.

5. The knot protector of claim 1 , wherein the plurality of material layers are secured by reflective stitching.

6. The knot protector of claim 1 , wherein the sleeve comprises one or more visual safety indicators.

7. The knot protector of claim 6 , wherein the one or more visual safety indicators are located along the base section of the lower portion.

8. The knot protector of claim 1 , wherein the upper portion defines an exterior surface and an interior surface with one or more orifices formed in the exterior surface, a cavity defined between the interior surface and the exterior surface, the one or more orifices in communication via the cavity.

9. The knot protector of claim 8 , wherein a string is positioned within the cavity and exits the one or more orifices, wherein the string is configured to tighten the upper portion of the sleeve around the knot of the rope.

10. A knot protector comprising:

a sleeve formed from a deformable, continuous web, wherein the sleeve defines upper and lower portions;

wherein the upper portion defines a first opening and the lower portion defines a second opening, and wherein the first opening defines a diameter that is smaller than a diameter defined by the second opening;

wherein the sleeve includes one or more receptacle loops positioned on the lower portion, wherein the lower portion includes a first receptacle loop located along a top section of the lower portion and a second receptacle loop located along a base section of the lower portion;

wherein the sleeve is further defined by a plurality of material layers defined as exterior and interior layers, wherein the exterior layer is defined as a 1000 denier nylon material, and wherein the interior layer defines a 1000 denier nylon material and/or a 1680 denier nylon material and wherein the interior and exterior layers define a herringbone nylon weave material, wherein the herringbone nylon weave of the exterior layer is formed from a 0.25 inch thick nylon webbing;

wherein the plurality of material layers are secured by reflective stitching;

wherein the sleeve comprises one or more visual safety indicators, wherein the one or more visual safety indicators are located along the base section of the lower portion;

wherein the upper portion defines an exterior surface and an interior surface with one or more orifices formed in the exterior surface and a cavity defined between the interior and exterior surfaces, wherein the one or more orifices are in communication via the cavity;

wherein a string is positioned within the cavity and exits the one or more orifices, wherein the string is configured to tighten the upper portion of the sleeve around a knot of a rope; and

wherein the knot protector is configured to receive the knot from the rope situated within the upper portion.

11. The knot protector of claim 10 , wherein the sleeve further defines a shoulder portion.

12. The knot protector of claim 11 , wherein the shoulder portion is positioned between the upper and lower portions.

13. The knot protector of claim 12 , wherein the shoulder, upper, and lower portions are connected into a single member and define the sleeve.
