Title: Elastomeric member

Abstract

An energy storage device is disclosed consisting of a stretched elongated elastomeric member disposed within a tubular housing, which elastomeric member is adapted to be torsionally stressed to store energy. The elastomeric member is configured in the relaxed state with a uniform diameter body section, and transition end sections, attached to rigid end piece assemblies of a lesser diameter. The profile and deflection characteristic of the transition sections are such that upon stretching of the elastomeric member, a substantially uniform diameter assembly results, to minimize the required volume of the surrounding housing. Each of the transition sections are received within and bonded to a woven wire mesh sleeve having helical windings at a particular helix angle to control the deflection of the transition section. Each sleeve also contracts with the contraction of the associated transition section to maintain the bond there between. During manufacture, the sleeves are forced against a forming surface and bonded to the associated transition section to provide the correct profile and helix angle. 12 figs.
