GB2613496A - Load strap for compactible loads - Google Patents

Abstract

A load strap is provided with a load compaction compensator (1) comprising a compensator web (2) and a tension spring (3). The compensator web and spring each extend between first and second fix points (7, 8) interrupting the load strap. The span of the compensator web (2) exceeds the effective rest length of the tension spring so that when tension is applied to the load strap to secure a load the tension spring is extended to an extension less than its elastic limit. If the load compacts, the compensator shortens the load strap to maintain the security of the load.

Claims (1)

1. Claims A load strap for securing compactible loads comprising: a compensator (1 ), said compensator comprising a first fixed point (7,) formed in length of webbing, a second fixed point (9) formed in the length of webbing and spaced longitudinally from the first fixed point: a tension spring (3) having a first end attached to the first fixed point and a second end attached to the second fixed point, said tension spring having an effective end to end length â Râ in a relaxed condition; a compensator web part (2) having a span â Sâ secured at a first end to the first fixed point and at a second end to the second fixed point, wherein the span of the compensator web part substantially exceeds the effective length of the tension spring to form a slack loop when no tension is applied to the load strap and on application of tension to the load strap allows the tension spring to extend to a maximum extension less than the elastic limit of the tension spring. A load strap according to claim 1 wherein the first and second fixed points are each provided by a sleeve extending laterally across the webbing. A load strap according to any one of the preceding claims wherein the coil spring is connected to each of the first and second fix points by an intermediate wire loop (6,8) threaded one each through each sleeve, a hook formation provided at each end (4,5) of the spring (3) engaging in the wire loop. A load strap according to any one of the preceding claims wherein a ratchet reel mechanism (11) is secured to the compensator (1) by means of a connector web (10) extending from the first fixed point to secure in a buckle formed in the ratchet reel. A load strap according to any one of the preceding claims wherein a webbing part (12) extends from the second fixed point to an end provided with a securing hook or loop

   1. (13). A load strap according to any one of the preceding claims wherein a reel webbing part (14) is coiled onto the reel of the ratchet reel drive (11) and extends away from the ratchet reel drive to an end provided with a securing hook or reel (15). A load strap according to any one of the preceding claims wherein the tension spring is a coil spring. A load strap according to anyone of claims 1 to 3 wherein the compensator is secured at each of the first and second fix points to interrupt a length of webbing (16) in a load strap wherein one free end of the webbing is provided with a cam buckle (17) to receive the unembellished other free end of the webbing.
