Abstract
A picture frame comprises a molded frame member having a generally planar rear surface, a rectangular rear backing plate, and an elongate support. A generally rectangular housing recess on the rear surface defines an inner land, the inner periphery of which circumscribes the window aperture of the picture frame. Opposing peripheral walls in the recess adjoining the land have respective elongate grooves formed therein for receiving a protruding fin on a first longitudinal edge of the backing plate. A slide aperture is formed centrally on the backing plate adjacent a second longitudinal edge including a recess on the front surface of the plate in communication therewith and extending to the proximate edge. A sliding catch positioned therein is engageable with a second groove of the housing recess to releasably secure the plate to the frame member. Two further apertures formed on a central portion of the backing plate are traversed by axis rods which protrude rearwards therefrom. A first end portion of the support has transversely disposed resilient sockets engaged with respective axis rods of the backing plate to hingedly attach the support therewith.
