Drawer latch

Abstract

A lock mechanism for a sliding drawer of the type mounted on telescopic slides in a cabinet includes a pivotal handle bar on the top front edge of the cabinet drawer front wall. The handle includes catch mechanisms biased for engagement with a strike extending from the drawer slides mounted on the inside of the cabinet. Manual rotation of the handle moves the handle and thus the catch mechanisms out of engagement with the strike enabling the cabinet drawer to be opened.
