<p>A slam latch for securing a panel such as a slidable window or door to a corresponding second panel or frame is disclosed. The slam latch includes a cover (16), a base (14), a torsion spring and a keeper (12). The keeper is mounted to one panel (102) and the cover, base and torsion spring are mounted to another panel (100). The panels are relatively movable between closed and open positions. The cover is pivotally supported by the base and is movable between closed and open positions. The torsion spring biases the cover toward the closed position. As one panel is moved relative to the other and into the closed position, a cam surface (42) on the keeper causes the cover to move such that an opening in the wall of the cover is presented for receiving the keeper. Once the panels are in the closed position, the cover is returned to the closed position by the action of the torsion spring, thus the cover captures the keeper and secures the panels in the closed position.</p> |
