Abstract
A rotational and axial control spring includes a tubular casing, a shaft, and a plurality of elongated elastomeric members. The casing comprises a tubular cross sectional equilateral convex polygon shape, the tubular shape extending uniformly between a first and second casing end. The shaft is fabricated having a cross sectional shape mimicking the equilateral convex polygon casing shape, a series of exterior surfaces extending longitudinally between a first smaller end and second larger end, wherein the exterior surfaces form a square frustum shape. The elastomeric members are formed as cylindrical frustums. The shaft is inserted within the casing interior. Each elastomeric member is positioned contacting a respective shaft exterior surface and a pair of adjacent casing interior surfaces. The elastomeric members provide rotational spring with adjustable resistant force and dampening functions. The tapered features provide an axial retention function.
