A panel for an overhead sectional door includes an exterior skin on an exterior-facing side of the panel and an interior skin on an interior-facing side of the panel that define a plenum. An insulating material is disposed in the plenum. An upper backer strut is disposed in the plenum proximate a top leading edge of the interior skin and extends across a full length of the panel. A lower backer strut is disposed in the plenum proximate a bottom leading edge of the panel and extends across a full length of the panel. The upper backer strut and the lower backer strut each include first and second strut legs extending into the plenum. The first and second strut legs are spaced from the exterior skin. Hardware is attached to the panel by fastening the hardware to one of the upper backer strut and the lower backer strut.

The present disclosure is directed to overhead door assemblies and operating systems. Disclosed herein is a drive drum that is compatible across a variety of overhead door types, including, for example, standard lift doors, vertical lift doors, and high lift doors. The drive drum of the present disclosure comprises a first cable groove section and a second cable groove section, opposite the first cable groove section, wherein at least one of the first cable groove section or the second cable groove section is in a non-linear graduated arrangement.

An overhead bi-fold door mounted on a freestanding header has a door lift device with polymer cylindroids and capstans operated with an electric motor driven power transmission to selectively move the bi-fold door from an upright closed position to a folded open position and allow the bi-fold door to move from the folded open position to the upright closed position. Anchors mounted on the bi-fold door adjust the working length of the cylindroids between the capstans and anchors. The capstans have laterally spaced disks engageable with the cylindroids during the helical winding and unwinding of the cylindroid on the capstans as the bi-fold door moves at an increasing rate of speed from the upright closed to folded open positions and a decreasing rate of speed from the folded open to upright closed positions.

A control method of the present disclosure causes a computer of an information apparatus to: display an operation icon on a display screen of the information apparatus, the operation icon causing an operation screen for an electric curtain device to be displayed; display the operation screen for the electric curtain device when selection of the operation icon is sensed, the operation screen including a curtain image representing a curtain of the electric curtain device; and when a pinch-out operation is sensed on the operation screen, output to a network a first open control command for opening the curtain of the electric curtain device.

An electrical connection device connects to a sectional door, the sectional door having a plurality of connected panels which roll along left and right tracks which are connected to a structure, the sectional door is positionable to a closed position and to an open position. The electrical connection device includes a slide which carries a reciprocating electric contactor. A housing has a slot, a proximal end and an opposite distal end. The slide slides along the slot in the housing. A spring in the housing biases the slide toward the distal end of the housing. The housing is connectable to either the left track or to the right track of the sectional door.

Apparatus for connecting a wiring harness to a sectional door is disclosed. The sectional door has a plurality of panels in which adjacent panels are connected by a hinge, the hinge is connected to the adjacent panels by first and second hinge connectors. The apparatus includes a first bracket which has a proximal end and an opposite distal end, the distal end is shaped and dimensioned to receive the wiring harness. The proximal end of the first bracket is connectable to the hinge by the first hinge connector. A second bracket has a proximal end and an opposite distal end, the distal end is shaped and dimensioned to receive the wiring harness. The proximal end of the second bracket is connectable to the hinge by the second hinge connector. The wiring harness is connected to the distal ends of the first and second brackets, thereby providing strain relief for the wiring harness.

The present invention includes a system for protect a vehicle from damage. Specifically, a non-marking protector is attached to a garage door arm to prevent damage that may occur when the rear lift hatch of a vehicle is opened and makes contact with the garage door arm. The rear lift hatch will contact one or more non-marking protectors instead, thereby ensuring no damage is caused.

The protective garage door cover comprises a composite textile, a plurality of fasteners, and a garage door. The garage door further comprises a plurality of door panels. The plurality of fasteners attach the composite textile to the garage door. The protective garage door cover forms a protective cover over the garage door. The protective garage door forms an insulating structure that insulates the garage door. The composite textile is a flexible structure such that the composite textile will bend with the garage door as the garage door is opened and closed.

The invention relates to an assembly (1) comprising a housing with a balancing spring break protection mechanism, said assembly (1) being configured for connecting a connector (15, 42), such as a bayonet connector, of a balancing spring of a sectional door system to said assembly, said housing being for connection with a fixed structure and comprising a first housing plate (5) comprising an opening (16) for receiving a balancing axle (60) of said sectional door system, said balancing axle (60) being connected to said balancing spring, and an aperture (11) for receiving said connector (15, 42), said spring break protection mechanism comprising a bearing and ratchet wheel unit (4, 7), said ratchet wheel (4) including a shaft (50) for receiving said balancing axle (60).

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.
