Claims
- 1. 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.
- 2. Flexible rigging chain as set forth in claim 1, in which each loop comprises a core formed of a circularly wound synthetic plastic strand of multiple loops and said outer casing being a textile material.
- 3. Flexible rigging chain as set forth in claim 2, in which said textile material is a synthetic plastic fabric and said loops are of generally uniform ring size.
- 4. Flexible rigging chain as set forth in claim 3, in which each loop of said chain has a longitudinally tensioned length selected in multiples of one foot and each loop is consecutively numbered from one end of the chain to the opposite end thereof.
- 5. Flexible rigging chain as set forth in claim 3, in which each loop of said chain is rotatable relative to the loops with which it is linked.
- 6. 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.
- 7. Method of fabricating a rigging chain as set forth in claim 6 in which the outer sheathing material is provided with a releasable closure means to enable periodic inspection of the core strand of each loop.
