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. In several embodiments, the elastic spring member comprises projections from the body of the latching device, at the end opposite to the latching lip, which are designed to squeeze into a constriction in the nesting site. In another embodiment, the elastic spring member takes the form of a finger projecting in cantilever fashion from the body of the latching device, which finger is compressed against an edge of the nesting site.
In accordance with a further modification, the upper surface of the body of the latching device is provided with one or more keyholes, and a separate tool for engaging said keyholes, and depressing a projection on said body for sliding said body back from a latched position, forcing body in unlatched position by engaging a flat boss on the inner end surface of said projection beneath the under surface of the nest panel.
