Latch

摘要

A latch arrangement (10) including:- a power operable actuator arrangement having a drive mechanism (11), an actuator (46) operable to move a driving abutment (70A, 70B, 70C) of drive mechanism, a latch bolt (14) having a closed position and an open position, a detent (22) having an engaged position at which it is capable of retaining the latch bolt in its closed position and a release position at which it frees the latch bolt for movement from its closed position, the detent including a driven abutment (89C) operable to move the detent from the engaged position to the released position, the drive mechanism having a clutch member (83) for selectively operably coupling the driving abutment with the driven abutment, the latch arrangement having:- a) a latched closed position in which the latch bolt is in the closed position and the detent is in the engaged position, b) an unlatched closed position in which the latch bolt is in the closed position and the detent is in the released position, and c) an unlatched open position in which the latch bolt is in the open position in which starting with the latch arrangement in the latched closed position, the clutch member lies in a first position and powered operation of the actuator causes the clutch member to selectively couple the driving abutment with the driven abutment and move the latch arrangement to the unlatched closed position, thereby causing the clutch member to follow a first path, subsequent movement of the latch arrangement to the unlatched open position causing the clutch member to follow a second path, subsequent movement of the latch arrangement to the latched closed position causing the clutch member to follow a third path with the first, second and third path being different.
