There is disclosed a rotatable mounting unit including two molded plastic parts, one of which is circular and adapted to be screwed to a counter, shelf, or the like as a base while the other part is rectangular and screwed to a television receiver of the like and acts as a platform therefor. The platform and base are secured together by placing a recess in the platform over a cylinder in the base in a manner to cause a post in the center of the recess to enter an opening in the center of the base with two lugs extending from the post passing through slots extending from the opening in the base. Upon rotation of the platform relative to the base the lugs slightly distort to firmly engage a flange around the opening in the base locking the two parts together but allowing them to be rotated. Detents consisting of button-like projections on the platform cooperating with holes around the cylinder of the base provide a detent function at approximately 20 degree intervals of rotation. Because the cylinder of the base extends into a recess in the platform, the overall height of the structure is low; screws are concealed when the unit is assembled.

A rotatable mounting unit for a cabinet or box comprising a base having a cylindrical projection comprising a recessed portion forming a flange with an opening in the center thereof, a plurality of equally spaced first detent elements around the top of said projection, at least one notch extending outwardly into said flange, a mounting platform having a circular rim thereon forming a recess to receive said projection, and a post having at least one lug extending radially therefrom which aligns with and passes into said notch for one rotational relation of said base and platform causing said lug to engage said flange and couple said platform to said base, said lug being positioned on said post so that it does not extend entirely through said notch and is resiliently deformable to pass out of said notch and onto said flange, said platform having a plurality of second detent elements located to match with said first detent elements for at least six relative rotational positions of said base and said platform.
