Abstract

See full text

A door latch system comprises an interchangeable latch assembly for securing a door to a door frame. The interchangeable latch assembly comprises a head and a latch mounted to the head. The latch is moveable between latched and unlatched positions. A driven member is operatively connected to the latch, the driven member moveable to latch or unlatch the latch. The door latch system further comprises a universal actuating assembly removably couple-able to the interchangeable latch assembly. The universal actuating assembly comprises a mounting bracket and a driving member releasably coupled to the driven member. Actuation of the universal actuating assembly translates the driving member and the driven member, moving the latch to the unlatched position. A first interchangeable latch assembly may be swapped with a second interchangeable latch assembly without requiring modification of the universal actuating assembly.
