Abstract
A swivel joint is designed to provide limited and controlled movement in two orthogonal planes running through its symmetrical center. The three major parts of the swivel joint are molded from a material composition of polycarbon-glass-teflon. A swivel top mounts to the object to be provided with controlled movement. A swivel bottom mounts to a support. The swivel top and bottom are held together by a large, curved wafer and a nut and bolt arrangement. The swivel top and bottom interact with each other to provide controlled limited movement in the two orthogonal planes, simultaneously.
Claims10
A swivel joint for permitting limited movement in two orthogonal planes, comprising:
- a swivel top having a recess therein, said recess having a surface of curvature defined by a first radius, an oblong aperture located adjacent said surface of curvature, its longer axis lying in a first orthogonal plane;
- a swivel bottom, having a surface of curvature defined by a second radius, two riser segments on the second radius surface of curvature, and an aperture in said second radius surface of curvature;
- and
- means for holding said swivel top and swivel bottom together in a nested slidable relationship.
