Abstract
Abstract This invention is directed to locking mechanisms for overlapping parallel sliding members, such as sliding doors, double sash windows and the like, comprising a hinge member having two leaf members, each of which has knuckles aligning with the other to receive a pivot pin; one of said leaf members being provided with means for permanently affixing it to one sliding member, and the other leaf member being freely pivotal. The freely pivotal leaf member has a spring loaded detent positioned transversely thereof, and the fixed leaf member has an aperture in a pivot knuckle positioned to receive the detent when the said leaf members are substantially perpendicular to each other. The freely pivotal leaf member has an arcuate recess in the free edge thereof adjacent the spring loaded detent, to provide access to said detent to release the locking of the detent from the aperture.
