Single-action latch

摘要

A single-action latch for use on a medical case which includes a storage tray and a closing lid includes a latch base with a mounting surface and rivet holes for attaching the latch base to the storage tray. A hook portion is pivotally attached to the latch base by means of a cylindrical pin. A release/closing lever is pivotally attached to the latch base by means of a cylindrical pin. A pair of oppositely-disposed connecting links is provided so as to interconnect the hook portion with the release/closing lever. The connecting links separate the hook portion from the latch base and the release/closing lever from the latch base. The latch is operable between a closed condition and an open condition and the lever is pivotally movable so as to transition the latch from the closed condition to the opened condition and then back to the closed condition. The positioning of the connecting links relative to the pivot axis of the lever ensures an over-the-center linkage arrangement so as to provide a positive snap-closed design.
