    Abstract: A door drive of a up and over door, sectional side or sectional ceiling door or sliding door, especially of a garage door, comprises at least one cylindrical guide tube supported against a ceiling or side wall, has a slide carriage arranged for movement along the guide tube, an endless traction element and a drive for opening and closing the door. The carriage is connectable with the door panel via a connecting rod. The ends of the traction element are secured together by means of a turnbuckle. For better support of the guide tube and for sampler connection or coupling of the traction element with the slide carriage, a number of mounting brackets are secured to the upper side of each guide tube for receiving support struts for mounting in the guide tube to the garage ceiling or wall. The slide carriage slides with a tubular portion along the guide tube. It has a continuous longitudinal slit on its upper side so that it can pass the brackets. The slide carriage has furthermore a lateral coupling element which can releasably be coupled with the turnbuckle. The turnbuckle comprises opposedly arranged a left-handed threads and a right handed threads, respectively, at each end for receiving anchor screws at the ends of the traction element permitting tensioning of the traction element.

    Abstract: A garage door operator for moving a garage door between open and closed posiitons includes a head unit for being held by a support structure positioned remote from the door with the head unit having a motor and a drive wheel with spaced teeth on its periphery for being driven by the motor. The operator also includes an elongate rail having a first end which is held by a support structure disposed adjacent and above the door with the rail including a pulley located adjacent the first end. The rail also includes a second end for being held adjacent to and in alignment with the drive wheel. The operator also includes a drive belt assembly for training about the drive wheel and the pulley and for being supported by the rail. The belt assembly includes a length of a plastic belt with teeth on one surface thereof matching the teeth on the drive wheel. The belt further assembly further includes a trolley for connection to the garage door and a first connector for joining one of the plastic belt to one end of the trolley. The connector includes a belt clip including a pair of spaced, aligned side walls with one side wall having an inside surface with undulations corresponding to the teeth of the plastic belt. The connector further includes a clip holder deformable from an as-formed position in which the holder can receive the side walls flanking the belt with the belt teeth aligned with the undulations, to a deformed position in which the holder firmly holds the side walls with the belt positioned therebetween.

    Abstract: A door operator for opening and closing an upwardly acting door and including a power unit having reversible motor means for driving the operator. The motor means is associated with a control circuit which includes upper and lower limit switches actuated when the door is in the opened and closed positions, respectively, which limit switches are connected in parallel and control the reversing of the motor rotation. The circuit also includes a reversing switch for reversing the motor rotation and door movement automatically if the door engages an obstacle during movement in the closing direction. Control means are associated with the reversing switch for deactivating same when the door is positioned closely adjacent but slightly spaced from its fully closed position to prevent undesired reversing of the door. The control means also includes means for deactivating the reversing switch when the door is positioned closely adjacent but slightly spaced from its fully opened position.

    Abstract: A drive mechanism engaging means is disclosed which may be used for a garage door operator to engage and disengage a chain as an example of a flexible drive member which is driven from a motor and speed-reducing drive train. The engaging means selectively engages and disengages a drive carriage from the chain so that in the event of electrical power failure, for example, the load carriage may be disengaged from the chain so that the garage door, which is fixed to the load carriage, may be manually operated to open and close the door. The engaging means may be actuated by a handle to be moved against a yieldable spring to stress the spring and thus release the load carriage from connection with the chain. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
