ABSTRACT:
A light-weight push, pull and/or torsion rod includes a light-weight core, fittings on either end, pins protruding from the outer surface of each fitting, and a tubular strength member surrounding the core and overlapping much of the end fitting. The strength member includes a fibrous braided layer which overlaps and closely captures the protruding tips of the pins to anchor the strength member to the end fitting. In one embodiment, the end fittings are conically tapered from the side adjacent the core and flare out from the narrow end of the cone, and the braid is woven tightly around the conical portion and flared portion of each end fitting so that the strength member abuts or bears against the end fitting when the rod is exposed to tension or compression forces. In another embodiment each end fitting is of substantially a straight cylindrical shape and the interengagement between the pins and the strength member is relied on more heavily for the transference of tension and compression forces between the end fittings and the strength member.
