Abstract
A device for displaying circular objects such as plates, pictures, mirrors and the like on a wall or other supporting structure. A frame formed with a circular-shaped central opening has a plurality of spaced lugs extending outwardly from its back surface. An annular shaped retainer ring is formed with a plurality of circumferentially spaced ramps which are engageable with the frame lugs for clamping the circular object against the back surface of the frame for visual display of the object through the frame opening. The ramps extend in an angular direction along the side of the retainer ring and provide axial movement of the retainer ring towards the frame when slidably engaged with the lugs to apply a clamping force against the circular object and to permit the mounting of objects of varying thickness on the display device. The ramps are provided with a series of ratchet teeth for locking the retainer ring in an adjustable object clamping position.
