In example implementations, a vertically stacking panel door system is provided. The vertically stacking panel door system includes a horizontal door guide, a panel interface zone, a vertical door guide, a plurality of panels to move from a horizontally stacked position in the horizontal door guide to a vertically stacked position in the vertical door guide, a counterbalance system comprising a motor to move the plurality of panels, and a sensor to detect a gap between two adjacent panels of the plurality of panels as the plurality of panels are moved from the horizontally stacked position to the vertically stacked position, wherein the sensor is to transmit a signal to the motor when the gap is detected.

A flexible unitary sandwich-like panel overhead door (11) consists of two relatively thin elastic sheets (12) and (13) connected by a plurality of elongated parallel web panels (14) which have supporting rollers (16) attached. The sheet-web connections are hinged (15) so that the panel may be flexibly moved from a closed vertical position to an open overhead nearly horizontal configuration. A rectangular beam (17), attached to the elastic sheets, provides additional stability and strength to the door structure. Additional embodiments are described.

An article of manufacture which provides structural support for overhead door track systems while concealing the tracks from view, consisting of vertical and horizontal members, which attach to and support the tracks, and which are manufactured with recessed channels or trim elements for visual concealment of the tracks.

A garage door roller assembly includes at least one track and a first panel and a second panel that are movable along the at least one track. The first panel and the second panel are connected by a hinge. The first panel and the second panel each have a first end portion including a planar surface, a recess defined in the planar surface, and a rail extending from a trough of the recess, the rail having a height that is less than a depth of the recess. A channel member is secured to the rail of the first panel. The channel member extends beyond the planar surface of the first panel and is configured to receive the rail of the second panel.

Track guards for use with overhead doors at loading docks, residential locations, and other facilities are described herein. In some embodiments, the track guards described herein can be two-part assemblies having a first part (e.g., a base member) that mounts directly to a door jamb, and a second part (e.g., an outer member or cap) that can be adjustably positioned relative to a door guide rail and then fixedly attached to the base member. In some embodiments, the outer member can include recesses or pockets, elongate edge features, and/or other shapes that are configured to clip onto or otherwise cover a portion of the guide rail to provide support and/or prevent, or at least reduce the likelihood of, damage from operational loads and/or impacts to the guide rail. Additionally, in some embodiments the track guards described herein can include various types of attachment features so that lights, reflective elements, motion sensors, fans, and/or other devices can be quickly and easily mounted to the track guard at various positions near the door opening to facilitate operations at the loading dock.

An overhead door having a plurality of unconnected panels. Each panel has a top and bottom edge interlocking retention geometry and end caps. The end caps engage dual track guide assemblies to completely separate the panels as the door is raised.

A garage door locking system that includes a single actuator locking box that integrates with existing garage door openers to form a system that is easy to install and that can not only open and close the garage door, but provide a sequential locking/unlocking function. The actuator utilizes a rack and pinion gear that moves the locking bar in a horizontal position to lock or unlock. A lighted indication LED extends from the system to the outside of the garage door so that the locked state of the door can be seen from the outside. The actuator box utilizes LED lights that light up to show proper alignment of the magnet mounted on the track Specialized clips both tie down the power cords from the actuator box and provide a magnetic activation that indicates to the CPU to move the bar to lock and also indicate the door position at all times.

Overhead door opening system that includes one or more torsion bars that twist when the overhead doors are moved from an open to a closed position manually or by an automatic opener having a motor so as to store potential energy in the torsion bars. Potential energy stored up in the torsion bars is released when the overhead doors are raised manually or by the automatic opener so that the released energy assists in lifting the overhead doors. The overhead door opening systems of the present invention do not require torsion springs that can fail over time.
