ABSTRACT:
A latch assembly which both selectively latches and accurately positions separable members relative to one another. The latch assembly includes pawls pivotably mounted on a first member, the first member being biased toward a separated position relative to a second member. The pawls, which are biased toward a latched position, are interconnected by a handle for selectively urging the pawls toward an unlatched position. The first member supports guide pins adjacent to the pawls, the guide pins having a positioning flange located thereon. The second member carries latching posts having a recess for receiving the guide pins and a shoulder accurately positionable relative to the second member. The shoulders have oppositely facing surfaces, one surface engageable by the flange of the guide pin and the other by a latching surface of the pawl when the first member is in its latched position. A compression spring located on the guide pins between the flange and the first member urges the members in the direction of separation when the surfaces of the shoulder are engaged by the flange and the latching surface of the pawl to effect positive latching action therebetween.
