ABSTRACT:
An improved resilient torsion arrangement. The torsion arrangement is comprised of a wire-like body member having an upper portion formed in a first predetermined open geometrical configuration, a transverse portion extending across the first predetermined open geometrical configuration, and a lower portion having a second predetermined open geometrical configuration. The upper portion and the lower portion are resiliently movable toward, or away from, each other to put the transverse portion into torsion. The torsion in the transverse portion provides the resilient force resisting movement of the upper portion toward the lower portion. Proper selection of the relationships between the upper portion and the lower portion and configuration of the transverse portion can provide predetermined relationships between the force required to move the upper portion toward, and away from, the lower portion and the separation between the upper portion and the lower portion.
