摘要： 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.

摘要： A clutch assembly for a roller door operator, the clutch assembly providing selective engagement with a drive wheel, the clutch assembly comprising: a rotatable shaft rotatable relative to the drive wheel; a clutch disc supported in a clutch lever and arranged to rotate with the rotatable shaft, the clutch disc and clutch lever configured to rotate relative to one another around the axis of rotation of the shaft; and a clutch cam supported in a clutch base, the clutch base configured to permit operative rotation of the clutch cam around the axis of rotation of the shaft in a first direction; wherein the clutch lever is operatively associated with the clutch cam so that rotational movement of the clutch lever in a second direction opposite to the first direction actuates movement of the clutch disc and the clutch lever axially along the rotatable shaft to engage or disengage the clutch disc with the drive wheel, and subsequent rotational movement of the clutch lever in the first direction actuates rotational movement of the clutch cam relative to the clutch base in the first direction.

摘要： The present invention relates to a remote control device (10), comprising one or more command buttons, each of which, when operated, directly or indirectly generates a command signal. The device includes a determination module (20) for determining a button-held-time parameter associated with the operation of a command button; and a transmitting module (18) that is configured to transmit the button-held-time parameter in association with the command signal.

摘要： A device for a track- or rail-mounted closure drive assembly can include a lever and cam arrangement configured to drive an engagement member between an engaged position and a disengaged position, the engaged position allowing motor drive of a closure and the disengaged position disconnecting the drive from the motor to the closure; and a rotating body including one or more camming surfaces and one or more peripheral surfaces, the peripheral surfaces including visual indicia to indicate to a user an orientation of the one or more camming surfaces and hence whether the engagement member is in the engaged position or the disengaged position.
