ABSTRACT:
A display mount includes a pair of interlocking portions. An aperture or slot is defined in one portion and a protrusion is formed in the other portion. During assembly, the protrusion is inserted into the aperture or slot. To retain the protrusion in the slot, the protrusion is formed with an enlarged element, and a resilient tab prevents disengagement of the enlarged element from the aperture or slot. The enlarged element, for example, has a ledge defining an underside surface and an outer surface above the underside surface. The resilient tab is disposed adjacent the aperture or slot so that the outer surface of the ledge abuts against the outer surface of the tab to deflect the tab inward during assembly, to release the tab when the enlarged element is moved within the aperture or slot, and to prevent disengagement of the protrusion from the aperture or slot by interference of the underside surface of the ledge with an inner surface of the tab. To further retain the protrusion in the slot, the enlarged element is asymmetrical, and after assembly the angular position of one portion with respect to the other is limited to a predefined range by a pair of protruding stops engaged in respective portions of a figure-eight shaped recess.
