## Abstract

A cargo securing system which incorporates synthetic chains in a manner which addresses the increased pitch of the synthetic link and the increased elongation of the synthetic chain, while still allowing the usage of conventional prior art load binders in a timely and safe manner. The system includes a length-adjusting coupling device for connecting a load binder to a section of chain.

## Claims

### Claim 1

A length-adjusting coupling device for connecting a load binder to a section of chain, said load binder including a chain-engaging notch, said chain having a link pitch P1, said coupling device comprising:
a) an elongate tubular body having first and second ends;
b) a hook connected to said first end of said elongate body;
c) an adjustable leg having first and second ends and being sized to telescopically travel within said elongate body, said first end of said leg including an attachment lug configured to engage said chain-engaging notch of said load binder, said adjustable leg having a stroke length L1; and
d) a locking mechanism for fixing said leg with respect to said body at a plurality of telescoped orientations and for transferring loads from said hook to said attachment lug;
further comprising a collar connected to and enclosing said second end of said elongate body;
wherein said locking mechanism includes:
a) an engagement member cooperating with said collar; and
b) a plurality of locking stops positioned along the length of said adjustable leg; and
wherein said locking stops include a plurality of evenly spaced circumferentially-extending grooves formed along the length of said adjustable leg, each of said grooves defining a distance T extending in a direction along the length of said adjustable leg; and
wherein said stroke length L1 is equal to or slightly greater than said pitch P1, and wherein said distance T is equal to or less than one fourth of pitch P1.

### Claim 2 (depends on 1)

The coupling device according to claim 1, wherein said collar includes an aperture sized to allow said adjustable leg to telescopically travel within said body, and wherein said engagement member is supported by said collar.

### Claim 3 (depends on 2)

The coupling device according to claim 2, wherein said collar includes a pair of pivotally mounted levers, each of said levers having a thumb-engaging shoulder for pivoting said levers, each of said levers further including an engagement shoulder for engaging one of said grooves on said adjustable leg, said levers movable between a first released position wherein said adjustable leg telescopically slides within said elongate body and a second locked position wherein said engagement shoulder is positioned within one of said grooves located on said adjustable leg thereby locking said adjustable leg with respect to said elongate body.

### Claim 4 (depends on 1)

The coupling device according to claim 1, wherein said hook is pivotally connected to said first end of said elongate body.

### Claim 5

A length-adjusting coupling device for connecting a load binder to a section of chain, said load binder including a chain-engaging notch, said coupling device comprising:
a) an elongate tubular body having first and second ends;
b) a hook connected to said first end of said elongate body;
c) an adjustable leg having first and second ends and being sized to telescopically travel within said elongate body, said first end of said leg including an attachment lug configured to engage said chain-engaging notch of said load binder; and
d) a locking mechanism for fixing said leg with respect to said body at a plurality of telescoped orientations and for transferring loads from said hook to said attachment lug;
further comprising a collar connected to and enclosing said second end of said elongate body; and
wherein said locking mechanism includes:
a) an engagement member cooperating with said collar; and
b) a plurality of locking stops positioned along the length of said adjustable leg;
wherein said locking stops include a plurality of evenly spaced circumferentially-extending grooves formed along the length of said adjustable leg;
wherein said collar includes an aperture sized to allow said adjustable leg to telescopically travel within said body, and wherein said engagement member is supported by said collar; and
wherein said collar includes a pair of pivotally mounted levers, each of said levers having a thumb-engaging shoulder for pivoting said levers, each of said levers further including an engagement shoulder for engaging one of said grooves on said adjustable leg, said levers movable between a first released position wherein said adjustable leg telescopically slides within said elongate body and a second locked position wherein said engagement shoulder is positioned within one of said grooves located on said adjustable leg thereby locking said adjustable leg with respect to said elongate body.
