Abstract: This invention relates to a one-piece latching device comprising a body of thermoplastic elastomer of specified durometer hardness having a substantially plane supporting surface, which is disposed in slidable relation in a recess or nesting site in a door or supporting panel, which comprises an elongated opening substantially in the plane of the supporting panel. One edge of the body, transverse to the supporting surface, terminates in a latching lip for engaging a striker bar or surface in cam-like fashion. The body is provided on its upper surface with means for providing a manual pull or thrust for retracting the latching lip and causing the body to slide in the direction of its opposite end, which terminates in an elastic spring member. The latter is compressed against an edge of the nesting site on the side opposite the latching lip imposing a spring-bias on the body, which causes it to slide in the opposite direction when the manual pull is released.

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.
