<p>An espagnolette handle assembly is locked when a handle head (20) is aligned with a backplate (17) and a lock (25) has been finger-pressed through a slideway (26) against a spring (51) for a locking pin (33) to enter a catch recess (35). The lock (25) is automatically held in this locking position by a spring-loaded latch pin (27) entering a recess in the head (20). To unlock the handle a key (29) is inserted and turned to withdraw the latch pin (27) allowing the spring (51) to slide the lock (25) to its unlocking position.</p> |
