Abstract:
A garage door bracing arrangement has a plurality of vertically extending door-stiffening column members, which are pivotally attached to upper mounting brackets affixed to garage building structure directly above the garage door opening. Lower mounting brackets are affixed to second ends of the column members and are anchored to the garage floor directly beneath the upper mounting brackets. The door-stiffening column members are configured as generally hollow, rigid, telescoping sections having longitudinal channels which retain fasteners that project from sides of the telescoping sections, so as to pass through holes in mounting brackets that affix the door-stiffening column members to the garage building structure, and deflection brackets that secure the column members to door panel hinge joints. The upper mounting bracket is configured to allow for a pivot swing type of movement, that eliminates pull stress from the upper bracket, when the bracing system is placed in an outward or suction condition created by high cross winds.
Abstract:
A counterforce assembly is described for use with doors that are exposed to high pressure differentials on the two sides thereof which result in large forces acting on the doors which tend to maintain the same closed against a door jamb and make the same difficult to open. The assembly includes a counterforce panel. The panel is typically hingedly mounted and has one major side thereof covered by a pressure shield. The covered side is vented to the low pressure side of the door and maintained at the low pressure while the other major side of the panel is exposed to the high pressure side, so that the panel is exposed to the same pressure differential as is the door and a resulting net force acts on the panel. Coupling means, which may be in the form of a pressure plate, a fulcrum arm, a linkage or a pulley arrangement, is connected to the panel and releasably connected to the door for applying the force acting on the panel to the door and counteracting the force acting on the door until the latter is opened and the pressures on the two sides of the door are equalized. The panel thereby counteracts the forces acting on the door and facilitates opening of the latter irrespective of the magnitudes of the pressure differentials to which the door and panel are exposed.
Abstract:
An articulated attachment assembly and a rail system and method of installation for rail installations in which there is an elevational change between vertical supports, in which the articulated attachment assembly eliminates the need for field mitering of components and provides instead a first articulated hinge assembly having a first mounting block to be attached to the first support, a second mounting block to be attached to the first rail connection block, and a hinge member to couple the second mounting block to the first mounting block and enable the second mounting block, the first rail connection block, and the rail to pivot together relative to the first mounting block and the first support.
Abstract:
A multi-panel overhead stacking door which allows for the addition of multiple panels across an opening width. A vertical extrusion acts a guide for the panel above and/or below it. The vertical extrusion serves as a moving guide which thereby allows for the relatively easy addition of multiple panels. At each end of the door is a series of formed parts that are attached to the ends of the end panels and movably maintained with door guides. The assembled door is driven by, for example, a driven shaft, positioned at the top of or above the door opening. The shaft comprises drums to windingly and unwindingly receive a lifting member. The lifting member runs from the drum to the bottom panel assembly behind each vertical extrusion.
Abstract:
A corner piece is provided for interconnecting frame members. The corner piece includes a first plate member defining an inner face, an opposite outer face, a first side face, an opposite second side face, and an end face. The first plate member including a bolt-receiving bore therethrough. A second plate member defines an inner face contiguous with the inner face of the first plate member, an outer face, a first side face, an opposite second side face, and an end face. The second plate member includes a bolt-receiving bore extending between the inner face and the outer face thereof along a first axis generally parallel to the inner face of the first plate member.
Abstract:
The present invention provides an intelligent control system for remote control of doors and windows, comprising an intelligent control end, a server and a control terminal of doors and windows. The intelligent control end sends a remote control command to the control terminal of doors and windows through the server. The control terminal of doors and windows processes the received remote control command and executes a corresponding control action to finish remote control of doors and windows, wherein the control terminal of doors and windows comprises an MCU. The MCU is connected with a signal receiving/transmission component, a mechanical component for control of doors and windows, a detection component of doors and windows, a position detection component of doors and windows and an anti-theft component. In the intelligent control system for remote control of doors and windows of the present invention, the intelligent control end sends a control signal to a remote control terminal of doors and windows for realizing remote control of doors and windows. The intelligent control system has the characteristics of simple system design, ultra-low power consumption and large-scale use, and can be used for remote control of diversified doors and windows like skylights, flat open doors and windows, doors and windows opened inside and outside, sliding doors and windows, etc.

Abstract:
A door hoist includes a bracket, drive sprocket, ring gear, hub assembly, set of planetary gears, and governor shaft. The drive sprocket has a drive sprocket axis. The ring gear is fastened to the drive sprocket. The ring gear has a ring gear axis that is in alignment with the drive sprocket axis. The hub assembly includes a connector to receive a door drive shaft and secure the door drive shaft in a fixed rotational alignment with the hub assembly. The set of planetary gears is rotationally mounted to the hub assembly. The set of planetary gears is configured to mate with the ring gear. The governor shaft includes a sun gear, brake assembly, and link. The sun gear is configured to mate with the set of planetary gears. The brake assembly has an engaged position and a disengaged position. The sun gear is rotationally fixed relative to the bracket in response to the brake assembly being in the engaged position. In response to the brake assembly being in the disengaged position, rotation of the sun gear is unfixed relative to the bracket. The link secures the brake assembly in the engaged position. The link is configured to melt in response to an ambient temperature exceeding a predetermined temperature.
