Abstract: Adjustable traction is provided in a traction cleat by selectively restricting or not the amount of flexure permitted for a dynamic traction element on the cleat. Restricting flexure is alternatively achieved by an adjustably positionable ring or by rotating the cleat to align the dynamic element with different shoe sole topographical features. A dual locking post is provided to reduce the surface area required on the cleat hub for locking structures. The cleat is formed in a two shot molding process that permits elongations of the dynamic traction elements without sacrificing the integrity of the cleat structure.

Abstract: An adjustable roll and support mechanism for elongate objects having a round cross-sectional configuration has a support base having a pair of parallel upright tubular members having rigid or collapsible support legs. Elevation posts are positioned in movable telescoping relation within respective tubular members and support a roll positioning head having an internal roll positioning mechanism. A pair of roll assemblies are movably supported on the roll positioning head. Lock rings are positionable at a locking position to restrain downward movement of the elevation posts relative to the tubular members and are positionable at a release position permitting downward movement of the elevation posts. Lock ring stops are mounted to a transverse structural member and are positioned to prevent the lock rings from becoming bound after being struck by a lock release mechanism.
