Abstract (en)
A handle (6) is linked by co-operating flanges to a plate (14) by a bolt nose (2). The plate (14) can be moved independently by a lock mechanism (13) acting to rotate the plate (20) which will engage a pin (21) on the plate (14) to withdraw the bolt nose (2) into the body (1). The locking mechanism (13) incorporates a slot which, upon rotation, can be located in one or other of a pair of notches (28) in a hold plate associated with the plate (14) so as to lock the bolt in either the withdrawn or extended positions. A deadlatch nose (5), when withdrawn into the body (1), moves an associated plate (40) so as to allow a pin 48 to enter a notch so that a moulding (46) can rotate and allow a pin (47) to enter a notch (53) in the plate (14) (when the bolt nose (2) is extended) and thus hold the plate (14) against movement allowing the bolt nose to be withdrawn.
