<p>A latch assembly comprising a latch frame mounted to a door. A latch bolt is mounted to the latch frame for pivotal movement between a biased position extended position and a retracted position. The latch bolt includes a tip portion with opposing planar locking and shaped engagement surfaces. A link is pivotally mounted to the frame for movement between a biased blocking position and a release position. In the blocking position the link prevents movement of the latch bolt from the extended position. A push bar pivots the link to the release position in response to an applied force. A frame bolt is mounted to a door frame for linear displacement between a position projecting from the door frame and a position displaced toward the door frame. The frame bolt includes opposing engagement and planar locking surfaces. When the door is closed the planar locking surfaces are in opposing surface-to-surface contact securing the door to the frame.</p> |
