US Patent 7201407 Sliding panel latch

A latch includes a cup adapted for mounting to a first member, snap legs for securing the cup to a first member, and a lever supported by the cup. The lever pivots about a pivot axis that is linearly movable relative to the cup. The lever includes a crossbar that is capable of engaging a keeper that is fixed relative to a second member. The crossbar is confined by the cup to move in a substantially straight linear direction that is perpendicular to the direction of motion of the pivot axis of the lever relative to the cup as the lever is moved pivotally about its pivot axis. The first member moves in a straight linear motion toward its secured position as the lever is moved to its closed position while the crossbar is in engagement with the stationary keeper.
