Locking device for the handle of an espagnolette lock.

摘要

A locking assembly comprising an axially rotatable locking rod (3) and radial handle assembly (6) associated with a door (2) is provided wherein the handle (6) has a perforated ear (7) secured thereto. The perforated ear (7) co-operates with a stud (10) and latch assembly of the type in which a latch plate (11) is held in a bifurcation of the stud (10) by a pivot (12) and the latch (11) is rotatable about one end (14) of a slot (13) through which the pivot (12) passes to align the latch with the stud (10) and allow the perforated ear (7) to move on and off the stud (10). The latch (11) can be rotated to a position transverse the stud (10) and be moved to locate the pivot (12) away from the end (14) about which it is rotatable. A seal can be installed in the said end (14) of the slot (13) to seal the door (2) closed. <IMAGE>
