Abstract

A snap-in hinge assembly for mounting doors on door frames comprises a hinge with one of its leaves providing a plurality of spaced recesses, and a hinge leaf receiving receptacle mounted in a recess. The receptacle includes a reinforcing member having mounting portions secured to the frame or door and a seat portion defining a channel of a width dimensioned to receive the length of the hinge leaf. The seat portion has latch receiving recesses therein cooperatively positioned relative to the spaced recesses in the hinge leaf and a plurality of latch elements are disposed in the latch receiving recesses. Biasing elements bias the latch elements outwardly of the latch receiving recesses into the channel and they seat in the hinge leaf recesses when the hinge leaf is inserted thereinto. Thus, the door with one hinge leaf secured thereinto may be mounted on the door frame by inserting and sliding the hinge leaves into the channels of the receptacles to engage the latch elements in their recesses.
