Abstract: A latch assembly (10) is mounted to a follower door (275) of a double door (257). When the follower door (275) is closed while a primary door (259) of the double door (257) is closed, an actuation latch (131) of the latch assembly (10) is moved from a releasing position to a pressing position to move a latch (231) of the latch assembly (10) to a latching position engaged in a groove (37, 300) in a door frame (31) or in the ground (299). When the actuation latch (131) is moved from the releasing position to the pressing position while the follower door (275) is not in the closed position, the latch (231) is retained in an unlatching position, avoiding damage to the latch assembly (10).

Abstract: An anti-pick latch assembly (10) is mounted to a follower door (275) of a double door (257). The latch assembly (10) includes an actuation latch (131) normally extending beyond an end face (291) of the follower door (257) and a latch (231) movable between an unlatching position received in the follower door (275) and a latching position extending out of the follower door (275) into a groove (37) in a door frame (31). When the follower door (275) is closed while a primary door (259) of the double door (257) is closed, the actuation latch (131) is actuated to move a limiting member (90) to a locking position, moving the latch (231) of into the groove (37) of the door frame (31). The limiting member (90) in the locking position prevents the latch (231) from moving out of the groove (37) while the latch (231) is picked.

The lower supporting element, loaded by the compressive force in the latched state, is deflected against a stop and is held in that position. The paths of movement of the upper and of the lower supporting element are defined by the housing by way of guides. The path of movement for the lower supporting element runs substantially perpendicular to the path of movement of the upper supporting element.
