Abstract: A panel of a sectional door includes a panel frame and a sheet of material that is coupled to the panel frame. The panel frame includes a top frame member, a bottom frame member, a first side frame member and a second side frame member. The frame members include a rear surface and a front surface, and the front surface includes a ledge. The sheet of material is coupled to the front surface such that a bottom edge of the sheet rests on the ledge and a front surface of the sheet is unobstructed by the panel frame.

Abstract: An overhead door includes a plurality of articulating panels. At least one of the plurality of articulating panels includes a frame defining an opening, the frame having a ledge and a lip extending from the ledge into the opening and a transparent panel having a first side and an opposing second side. The transparent panel is positioned adjacent to both the lip and the ledge with the first side of the transparent panel positionable adjacent the lip. The plurality of articulating panels further includes a retainer member positionable adjacent the second side of the transparent panel and operable to be fastened to the frame.

Abstract: An impact rated frame for sectional doors includes a frame assembly sandwiching a shield member and securely clamping a planar portion of a sectional door. The frame assembly and the shield member are fastened together with a plurality of fasteners driven through the frame assembly and the shield member. The impact rated frame further includes a decorative frame affixed to the frame assembly. The decorative frame seals against the planar portion of the sectional door and the shield member to prevent the frame assembly from contamination. The shield member may be transparent or opaque with multiple louvers.

Abstract: A method is disclosed for making an improved insulated door panel having an outer and inner spaced apart skins and an internal foam core. The insulated door panel includes a first spacer disposed between a top end of the outer skin and a top end of the inner skin and a second spacer disposed between a bottom end of the outer skin and a bottom end of the inner skin. The first and second spacers include first and second protrusions, respectively, on an inner face of the first and second spacers. The first and second protrusions secure the first and second spacers to the foam core.

Abstract: A stored energy emergency barrier release device comprising a barrier and a barrel member for storing the barrier thereon. The barrel member is rotatable on a stationary counterbalance shaft and a push down shaft. The release device further includes a push down spring coupled to the push down shaft for storing potential energy in order to exert a closing force on the barrier when the release device is positioned from an engaged position to a released position. The release device includes a reset mechanism interfaced with the push down spring for transmitting a lifting torque to the push down spring in response to moving the barrier from a first position to a second position to store energy within the push down spring.

Abstract: A glazing system for use with a barrier that has a panel with an opening is disclosed. An impact glazing, which covers the opening, includes an inner surface and an outer surface and a plurality of apertures around its periphery. A fastener having a fastener head passes through each corresponding aperture and into the panel. The glazing system also includes an elastically deformable washer positioned between each fastener head and the impact glazing. The glazing system may also include an inner bezel covering the periphery of the glazing on the inner surface and an outer bezel covering the periphery of the glazing on the outer surface, wherein the bezels are secured to the barrier and the glazing by a corresponding piece of adhesive tape.

Abstract: A cable tensioner (20) for a sectional overhead door (D) having a motor-driven counterbalance system (30) including, a spring-loaded axle (31), cable drums (24) carried by the axle, cables (C) attached to and interconnecting the cable drums and the door and forming and releasing cable wraps (29) on the cable drums upon raising and lowering of the door, the cable tensioner having, a tension spring (31) adapted to be mounted on the sectional door having a first end (34) and a second end (35), the first end being adapted to engage the door and the second end being adapted to slidingly engage the cable, wherein the tension spring urges the second end to take up any slack in the cable.
