Track- or rail-mounted closure drive assembly
The invention provides a device for a track- or rail-mounted closure drive assembly for engaging and disengaging a moveable drive trolley (which serves to move the closure, such as a garage door) from the drive from a powered operator unit, the device including body on the trolley having a guiding surface, a rotating body having one or more camming surfaces, rotation of the rotating body about a rotation axis being supported by the guiding surface, and a lever having a lever camming surface configured to engage with one or more of the camming surfaces of the rotating body, wherein the lever is associated with an engagement member such that rotation of the lever moves the lever camming surface along the one or more camming surfaces to displace the engagement member, and wherein the engagement member is arranged to realise the engagement and disengagement between the moveable trolley and the drive component. By way of this mechanism, successive operation of a release means (ideally, in a direction at least partly away from the closure) toggles the engagement member between an engaged and a disengaged position with respect to the drive. The device may include a latch for latching the trolley with respect to the track or rail when the closure is in a closed position, the latch automatically releasing when the drive is operated to move the trolley.
