Claim 10:
11. A device for a track- or rail-mounted closure drive assembly, the device comprising:
a moveable trolley associated with a closure, the trolley configured for movement along the track or rail under drive by a drive component to move the closure between an open position and a closed position;
an engagement member arranged to provide selective engagement between the trolley and the drive component;
a mechanism configured to move the engagement member between an engaged position and a disengaged position, the engaged position allowing drive of the closure by way of the drive component, the mechanism having a user actuation means for manipulation by a user; and
a latch configured to latch the trolley to the track or rail when it is in a position associated with the closed position of the closure, the latch moveable between a latched position and an unlatched position under operation of the mechanism, such that manipulation of the user actuation means to move the engagement member into the disengaged position also has the effect of moving the latch into the unlatched position,
wherein the mechanism includes a rotating body with camming surfaces provided on a periphery of the rotating body and arranged to engage with an element associated with the latch and to move the latch between the latched position and the unlatched position.
