Abstract
A coupling for mounting and positioning photographic, motion picture and video accessories and the like. A mounting sleeve is adapted to be secured to an equipment supporting member. A fixed positioning disc depends from and is integral with the mounting sleeve. A cylindrical shaft is axially coupled to and extends from the fixed positioning disc. A first rotatable positioning disc is disposed about the cylindrical shaft, a frictional stabilizing member being disposed between the fixed positioning disc and the first rotatable positioning disc. A second rotatable positioning disc is annularly disposed about the cylindrical shaft in proximity to the first rotatable positioning disc. The adjacent surfaces of the first and second rotatable positioning discs have disposed therein reciprocally aligned pairs of linear channels of varying width and depth, each pair of linear channels being adapted to receive and secure equipment supporting shafts of differing cross section. A securing handle is coupled to the cylindrical shaft and is adapted to impose an axial force to engage the rotatable discs and thereby securely position each pair of aligned, linear channels at any position along a 360…
