Abstract
Non-metallic rigging chain formed with a plurality of linked flexible loops. Each loop has a core which consists of a continuous strand of non-metallic materially coiled upon itself. The coiled core material is sheathed within a woven outer fabric. Except for the two terminal loops of each chain, one loop is formed by coiling a continous strand of core material in linked relation within a pair of completed loops. The length of each chain is determined by the diameter of its loops and the number of loops linked together.
Claims7
Flexible rigging chain comprising a plurality of conformably flexible loops linked together, each loop defining an annulus including a core portion formed by a non-metallic strand coiled endlessly in a predetermined loop size and being sheathed in an unconsolidated condition within a flexible outer casing, each loop of the chain being interlinked with at least one other loop of generally the same construction, whereby each strand of said chain is adapted to be uniformly tensioned.
Method of fabricating a rigging chain comprising the steps of forming a first loop by endlessly coiling a flexible, non-metallic strand to form a circular annulus of predetermined size, forming a second loop by endlessly coiling a flexible, non-metallic strand into another annulus of predetermined size in which the endlessly coiled strand of the first loop and the endlessly coiled strand of the second loop are non-detachably interlinked together in a chain-type structure, and sheathing each loop making up said chain within a flexible outer casing material.
