Bifurcated latch bolt retained by primary and secondary pawls

摘要

A latch mechanism includes a latch plate 110 associated with a first object, and a claw 120 rotatably attached to the latch plate at 124. A toggle link 130 is rotatably attached to the latch plate at 134. A primary pawl 140 is rotatably attached to the toggle link 130. The primary pawl 140 retains the claw 120. A secondary pawl 160 is rotatably attached to the latch plate at 164. The secondary pawl 160 retains the toggle link 130. The arrangement retains the claw against a high force acting in the release direction but requires a low force to release the secondary pawl and allow primary pawl release.
