ABSTRACT:
A releasable mount for window grilles and the like. A wall-mounted portion is attached to a wall near the window and includes a fixed housing with a latch member having an opening therethrough and a trigger pin mounted for movement from a cocked, extended position to a release position. A grille-mounted portion is rigidly attached to the grille and includes a latch pin having a cavity with a catch assembly inserted into the fixed housing and partly through the opening in the latch member. The catch assembly expands to a catch position upon contact of the latch pin with the trigger pin. Then the catch assembly catches on the latch member and prevents the latch pin from being withdrawn from the fixed housing. The trigger pin remains biased in the cocked position, and keeps the catch assembly in its expanded position. However, when the trigger pin is moved to the release position, the catch assembly may retract and enable the latch pin to be withdrawn and separate from the fixed housing. A remote actuating assembly for actuating the releasable mount may include a suitable cable connected at one end to the trigger pin and extending through the wall and into the building. The cable preferably connects with a kick plate assembly, mounted on the wall inside the building, which in response to a pushing force imparts a pulling force on the cable on the kick plate.
