Abstract
A device for a closure drive assembly can include: a moveable trolley, the trolley configured for movement along a track or a rail under drive by a drive component to move a closure between an open position and a closed position, the trolley including a body 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 rotating body camming surfaces to displace the engagement member, and wherein the engagement member is arranged to provide selective engagement between the moveable trolley and the drive component.
