ABSTRACT:
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.
