ABSTRACT:
The latch (100) includes a catch (102) having a beveled edge (102A). An aperture (104) receives a downward force to release the catch from the lip (106A) of a housing (106). A stop (108) limits the downward movement of the latch. A retaining tab (110) traps the latch within the door pocket and limits the upward movement of the latch. The retaining tab includes a beveled surface (110A) to facilitate the insertion of the latch into the pocket. A cantilever spring (112) exerts an upward force on the latch when compressed. The latch, including all of its associated parts, can be plastic injection molded in a single-action mold. The door (200) includes a substantially parallelepiped pocket (202) having an opening at the top to receive the latch. The pocket includes a front aperture (202FA) in the upper, front surface (202F) of the pocket, and a rear aperture (202RA) in the lower, opposing rear surface (202R). When the latch is inserted into the pocket, the beveled retaining tab temporarily deforms the rear surface (202R) of the pocket and then snaps into place. When assembled, the latch aperture (104) is positioned in the front aperture (202FA) of the pocket, while the retaining tab (110) is positioned in the rear aperture (202RA) of the pocket. When closing the door, the beveled edge (102A) of the catch contacts the outer surface of the housing (106) and forces the latch down.
