Abstract

A lightweight and flexible load bearing shackle that is configurable in operation. The shackle includes a bow made of a plurality of loops of synthetic fiber rope (e.g., polypropylene, nylon, polyester, polyethylene, Aramid, acrylic, co-polymer fibers) within a sheathing. The sheathing is secured together to form a receptacle (opening) in each leg of the bow that has a boot located therewithin. The sheathing and the boot may be secured together using a cover. The boot may include an enclosed channel that the sheathing is routed through to secure the bow and the boot. The boots include threaded holes passing therethrough where one threaded hole is larger than the other. A connection pin having two threaded portions (one portion larger than the other) separated by a non-threaded portion is used to secure to the boots and maintain the ends a certain distance apart (length on non-threaded portion).

Claims21

Dependent claims

A lightweight load bearing shackle comprising:

a bow formed from a plurality of loops of fiber rope, wherein the plurality of loops are substantially aligned with one another and are secured together to form a single loop, wherein a first side of the single loop is secured to a second side of the single loop along a center portion of the single loop, wherein the first side and the second side of the single loop are not secured together at a first end and a second end so that the first side of the single loop and the second side of the single loop form a first receptacle at the first end and a second receptacle at the second end;
a first boot located within the first receptacle, wherein the first boot includes a first threaded opening;
a second boot located within the second receptacle, wherein the second boot includes a second threaded opening, wherein the second threaded opening is smaller than the first threaded opening;
and
a connection pin having a first threaded portion and second threaded portion separated by a non-threaded portion, wherein the second threaded portion is smaller than the first threaded portion, and wherein the first threaded portion is to be threaded into the first threaded opening and the second threaded portion is to be threaded into the second threaded portion and the non-threaded portion is to be located therebetween to keep the first and second receptacles a distance equal to length of the non-threaded portion apart.

2 more elements

A method of making a lightweight load bearing shackle, the method comprising:

wrapping a fiber rope into a plurality of loops;
placing the plurality of loops into a sheathing;
securing a first side of the sheathing to a second side of the sheathing along a center portion thereof, wherein the first side and the second side not secured together at a first end create a first receptacle and the first side and the second side not secured together at a second end create a second receptacle;
placing a first boot within the first receptacle so that the first receptacle is located within a first channel formed in an exterior of the first boot;
placing a second boot within the second receptacle so that the second receptacle is located within a second channel formed in an exterior of the second boot;
and
securing a pin having a first threaded portion and a second threaded portion separated by a non-threaded portion to a first threaded hole in the first boot and a second threaded hole in the second boot, wherein the securing the pin includes passing the first threaded portion of the pin through the second threaded portion in the second boot and screwing the first threaded portion into the first threaded hole and the second threaded portion into the second threaded hole.
