ABSTRACT:
One-piece latches or door-retenting devices of elastomeric material of specified parameters, are constructed for disposition in the surface of a door or other supporting panel so that at least one lip projects outwardly from the edge or surface in elastically deformable relation to engage a striker bar or surface. A first type includes and elongated lip projecting or depending from one edge, the inner surface of the lip forming a slot which just accommodates the striker bar upon closure of the latch, the adjacent outer surface of the lip projecting in angular relation to the slot providing resilient latching action against the striker bar when the latch is opened or closed. Latch shapes of this type include "D" shape, "C" shape, round, square, polygonal and line configurations. A second type comprises a bellows-like latching member closed at one end with a protuberance in the form of an elastomeric bulb which is constructed to be elastically deformed by the striker bar or latching surface. Such a latch can be readily molded as an intergral part into a panel or container. Additional modifications include a shallow groove surrounding the body of the latch which is constructed to seat around the edge of an opening which has been cut in the closure accommodating the latch. These modified forms include tab latches having a single and a double lip, and knob latches including a round latch symmetrical about an axis through its center.
