Abstract:
An operator for a closure comprising a drive mechanism for controlling respectively pivotal movement of the closure relative to a closure frame and actuation of a fastening mechanism for securing the closure relative to the closure frame when the closure frame is closed wherein said drive mechanism comprises a drive input rotatable about a drive axis, a first drive output rotatable about a first axis offset from said drive axis for controlling pivotal movement of the closure between open and closed positions, a second drive output substantially co-planar with said first drive output and rotatable about a second axis offset from said drive axis for controlling the fastening mechanism for releasably securing the closure when closed, means for coupling said drive input to each of said first and second drive outputs in sequence whereby said first drive output is coupled to said drive input for opening and closing the closure when said second drive output is uncoupled with the fastening mechanism unlocked, and said second drive output is coupled to said drive input for locking and unlocking the fastening mechanism when said first drive output is uncoupled with the closure closed, and means for blocking rotation of each of said first and second drive outputs when uncoupled from said drive input.
