Abstract
A latch assembly for use with a panic exit device, particularly a top latch having a U-shape which engages a stem portion of a T-shaped receiving lug mounted overhead to a top member of the door frame. The U-shaped top latch is pivotably mounted to the active stile of the door. The latch assembly causes the U-shaped latch to pivot upward to capture the stationary T-shaped receiving lug, or pivot downwardly to disengage from the T-shaped receiving lug. The latch member is in sliding and abutting engagement with two latch plates which slide in one direction to retain the latch member in a downward orientation to hold the latch in an open position, and slide in an opposite direction to allow the latch member to pivot upwardly upon engaging pressure by the strike. A wedge is caused to slide into blocking engagement with the latch when it is in the closed position. The wedge is removed from the blocking position by movement of a panic bar of a panic exit device mounted onto the door, and the wedge, once moved to disengage from the latch member, allows the latch to pivot to the open position.
