Abstract: The present disclosure provides a barrier operator system in which a remotely located transceiver type controller is in wireless communication with a transceiver type adapter connected to a barrier operator, and in electronic communication with the barrier operator's microcontroller. The controller is operable to wirelessly transmit door operator status inquiries to the adapter. This may be effected automatically in connection with the transmission and receipt by the adapter of door toggle commands or separate and apart from same. The status information is wirelessly transmitted by the adapter in broadcast form without source or destination address to the remote device in a signal that is non-addressed broadcast door operator (and, indirectly, door) status information by relying upon the receipt of the message by the remote within the specific time limit of the reception window of the remote.

Abstract: A counterbalance system for an upward acting door includes a cable drum support shaft and a torsion spring drive mechanism mounted adjacent one or both sides of the door and drivably connected to the drum support shaft. The spring drive mechanism includes a torsion coil spring mounted on a frame and connected to a vertically oriented shaft which, in turn, is connected to an output shaft by way of a bevel gear drive. A spring winder device is connected to one end of the spring and to the frame. Indicia on the spring is viewable through a window on the mechanism frame for indicating the number of revolutions imposed on the spring to set a predetermined counterbalance torque.

Abstract: A sectional garage door panel includes a skin part formed of a rolled metal sheet forming an outer wall and opposed top and bottom edges which may form a pinch resistant joint when adjacent panels are interconnected. Elongated prefabricated insulation parts are inserted in cavities formed by the top and bottom edges and a generally rectangular planar insulation part is insertable in a cavity formed between the top and bottom edges and between the first mentioned insulation parts. Channel shaped brackets are insertable in cavities formed by the top and bottom edges for reinforcing the skin part at a point of attachment of end stiles and hinge parts. A metal backer sheet forms an inner wall to protect the insulation parts. The brackets and one or more of the insulation parts may be secured to the skin part by an adhesive.

Abstract: A handle assembly, particularly adapted for a sectional door panel includes identical handle parts each having a grip portion and spaced apart transversely extending legs. One of the legs of each handle part has an elongated shank extending therefrom and the other leg of each handle part has a shorter shank or a shank receiving bore formed therein. The handle parts are assembled to each other from opposite sides of a door panel and secured by conventional threaded fasteners which extend through a bore in one leg of each handle part and engage a shank of the other handle part. Tubular spacers may be sleeved over the shanks of the handle parts to limit the spacing between the handle parts during assembly to the door panel.

Abstract: Guide track assemblies for upward acting doors include substantially linear vertical and horizontal track sections and curvilinear transition sections formed as portions of each of the vertical and horizontal linear sections. The track assemblies are supported, respectively, by mounting brackets which also support a counterbalance mechanism for the door. The curvilinear transition track sections are formed integral with the vertical and horizontal track sections and may have a constant or elliptical radius of curvature, the latter to provide clearance for the guide track assemblies in low headroom installations. The mounting brackets are formed of stamped metal plates which are folded to provide a first flange for attaching the mounting bracket to a structural wall, a support part including a flag portion for connection to the guide track sections and a second flange for connection to a door counterbalance mechanism.

Abstract: A counterbalance system for an upward-acting door includes spaced-apart wall brackets and cable drums supported on the brackets and connected to flexible cables which depend from the drums and connected to the lower side edges of an upward-acting sectional garage door. One or both of the cable drums may be connected to one end of a torsion coil spring and the opposite end of each spring is connected to a hub assembly. Elongated spring winding and protective cover tubes are sleeved over the springs and are connected to the brackets by worm-gear drive winding mechanisms, respectively, for rotating the tubes to effect winding of the torsion coil springs through the hub assemblies but preventing rotation of the tubes during normal operation of the counterbalance system. The cable drums and spring hub assemblies may be supported on an elongated synchronizing shaft or a torque transfer shaft extending between and supported on the wall brackets.

Abstract: A counterbalance system for an upward acting door includes spaced apart wall brackets supporting a tubular shaft for spaced apart cable drums operable to wind counterbalance cables thereon to counterbalance the weight of the door. Torsion springs interconnect the cable drums and spring winder tubes sleeved over the springs and connected to the wall brackets by a winder mechanism including a support plate having spaced apart tabs adapted to register in corresponding slots formed in a wall bracket. The winder mechanism includes a worm gear drive including a ring gear which is connected to one end of the winder tube by an arrangement of radially inwardly projecting key portions in a bore of the ring gear which register with axial grooves formed in the winder tube and are adapted to slide into transverse slots intersecting the grooves. A removable lock pin is engageable with the ring gear or the worm of the worm gear drive.
