Abstract

Various embodiments of the present disclosure provide a hollow-braided rope having a new and improved rope termination formed therein and a new and improved rope termination system for forming the rope termination. Generally, the rope termination of the present disclosure is formed using a double-braided portion of hollow-braided rope in conjunction with a set of mechanical components of the rope termination forming system. The use of both the double-braided portion of the hollow-braided rope and the set of mechanical components causes any applied tensile forces to be distributed between the double-braided portion and the mechanical components. The distribution of part of any applied tensile forces away from the mechanical components and to the double-braided portion of the hollow-braided rope itself enables the mechanical components to be relatively small and lightweight and reduces the size and weight of the rope termination without compromising strength.

First claim

The invention is claimed as follows:

1. A rope termination forming system for forming a rope termination in a hollow-braided rope, the rope termination system comprising:
(a) the hollow-braided rope including (i) a first end, and (ii) an opposing second end having the rope termination formed therein, wherein the rope termination includes a double-braided portion of the hollow braided rope including an outer braid portion and an inner braid portion disposed within the outer braid portion and terminating in a tail, a portion of an outer surface of the inner braid portion near the tail contacting a portion of an inner surface of the outer braid portion;
rope inverter including a rope inverter body having a tapered rope inverter body outer surface, a rope inverter body inner surface defining a rope receiving channel through the rope inverter body, and a rope inversion surface connecting the rope inverter body outer surface and the rope inverter body inner surface, wherein the rope inverter is configured such that: (i) a portion of the outer braid portion of the double-braided portion of the hollow-braided rope is wrapped around at least part of the rope inverter body outer surface, (ii) a portion of the inner braid portion of the double-braided portion of the hollow-braided rope is disposed within the rope receiving channel through the rope inverter body, and (iii) a portion of the double-braided portion of the hollow-braided rope is wrapped around at least part of the rope inversion surface of the rope inverter body; and
(c) a socket including a socket body having a tapered socket body inner surface, the socket body inner surface defining a tapered bore through the socket body that forms a rope inverter receiving cavity configured to receive the rope inverter.

2. The rope termination system of claim 1 , wherein the socket is configured to be slidably disposed on the hollow-braided rope and the socket body inner surface and the rope inverter body outer surface are configured to clamp the portion of the outer braid portion of the double-braided portion of the hollow-braided rope wrapped around the rope inverter body outer surface therebetween when a tensile force is applied to the rope.

3. The rope termination system of claim 1 , which includes a tail retainer configured to be disposed within the inner braid portion of the double-braided portion of the hollow braided rope upstream of the socket.

4. The rope termination system of claim 1 , wherein the rope inverter body is formed of a single piece and the socket body is formed of a single piece.

5. The rope termination system of claim 1 , wherein the rope inverter body outer surface is frustoconical.

6. The rope termination system of claim 5 , wherein the socket body inner surface is frustoconical.

7. The rope termination system of claim 6 , wherein the socket body has a cylindrical socket body outer surface.

8. A hollow-braided rope comprising:
a first end; and
an opposing second end having a rope termination formed therein, the rope termination including:
(a) a double-braided portion of the hollow braided rope including an outer braid portion and an inner braid portion disposed within the outer braid portion and terminating in a tail, a portion of an outer surface of the inner braid portion near the tail contacting a portion of an inner surface of the outer braid portion; and
(b) a rope inverter including a rope inverter body having a tapered rope inverter body outer surface, a rope inverter body inner surface defining a rope receiving channel through the rope inverter body, and a rope inversion surface connecting the rope inverter body outer surface and the rope inverter body inner surface, wherein:
(i) a portion of the outer braid portion of the double-braided portion of the hollow-braided rope is wrapped around at least part of the rope inverter body outer surface,
(ii) a portion of the inner braid portion of the double-braided portion of the hollow-braided rope is disposed within the rope receiving channel through the rope inverter body, and
(iii) a portion of the double-braided portion of the hollow-braided rope is wrapped around at least part of the rope inversion surface of the rope inverter body.

9. The hollow-braided rope of claim 8 , wherein the rope termination further includes a socket including a body having a tapered socket body inner surface, the socket body inner surface defining a tapered bore through the socket body that forms a rope inverter receiving cavity configured to receive the rope inverter.

10. The hollow-braided rope of claim 9 , wherein the socket is slidably disposed on the hollow-braided rope and the socket body inner surface and the rope inverter body outer surface are configured to clamp the portion of the outer braid portion of the double-braided portion of the hollow-braided rope wrapped around the rope inverter body outer surface therebetween when a tensile force is applied to the socket.

11. The hollow-braided rope of claim 10 , wherein the rope termination further includes a tail retainer disposed within the inner braid portion of the double-braided portion of the hollow braided rope upstream of the socket.

12. The hollow-braided rope of claim 9 , wherein the rope inverter body outer surface is frustoconical.

13. The hollow-braided rope of claim 12 , wherein the socket body inner surface is frustoconical.

15. The hollow-braided rope of claim 8 , wherein the first end has a different rope termination formed therein.

16. The hollow-braided rope of claim 8 , wherein the rope inverter body is formed by introducing a liquid resin into the hollow-braided rope proximate the second end and enabling the liquid resin to harden.

17. A hollow-braided rope comprising:
a first end; and
an opposing second end having a rope termination formed therein, the rope termination including:
(a) a double-braided portion of the hollow braided rope including an outer braid portion and an inner braid portion disposed within the outer braid portion and terminating in a tail, a portion of an outer surface of the inner braid portion near the tail contacting a portion of an inner surface of the outer braid portion;
