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.

In example implementations, an end cap for a panel of a vertically stacking panel door is provided. The end cap includes a body to be coupled to an end of a panel of a vertically stacking panel door, a first track wheel coupled to the body, a second track wheel coupled to the body, and a vertical stability roller coupled to the body, wherein the first track wheel, the second track wheel, and the vertical stability roller are arranged along a vertical line, wherein the first track wheel is located vertically above the second track wheel and the vertical stability roller is located between the first track wheel and the second track wheel.

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.

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.

A roller shutter arrangement (1) includes a door leaf (2) including door leaf elements connected together to be angled and guided by guide rollers (23a, 23b) in lateral guides. The lateral guides each include an end portion accommodating the door leaf (2) in a closed position and a storage portion accommodating the door leaf (2) in an open position. The end portion and the storage portion are angled with respect to each other and are connected via a transition portion (42). The transition portion (42) includes guide paths on guide rollers on which predetermined guide rollers roll with a guide length between guide rollers corresponding substantially to a partition defined by a breadth of the door leaf element or to an integer multiple thereof. The so-called polygonal effect is avoided and higher movement speeds of the door leaf (2) are enabled while the service life is simultaneously increased.

The present disclosure relates to a door, in particular a sectional door, comprising a door leaf which includes several interconnected panels, pairs of track rollers which are connected with one of the several panels and which are designed to guide a respective panel in guide rails, wherein the door comprises an uppermost pair of track rollers, a bottommost pair of track rollers and at least one middle pair of track rollers, and the uppermost pair of track rollers, the bottommost pair of track rollers and the at least one middle pair of track rollers each run in separate guide rails, and wherein the guide rails of the uppermost pair of track rollers have a course which in one portion has a trough-like shape.

Embodiments of the invention provide a opening and closing assembly for a rigid door panel that is rotatably attached to a roller received within a track on a door frame member. A support member can be rotatably attached to the door panel. A first pivot arm can extend inboard from the support member to pivotally attach to an inboard frame member. Upon application of an upward force to the door panel, the first pivot arm can pivot with respect to the first inner frame member to move the support member in an arcuate path. The support member can thereby move the door panel upward and inboard along a door path at least partly defined by the track, with a lower end of the door panel not extending substantially outboard of the door frame member as the door panel moves along the door path.

In example implementations, an end cap for a panel of a vertically stacking panel door is provided. The end cap includes a body to be coupled to an end of a panel of a vertically stacking panel door, a first track wheel coupled to the body, a second track wheel coupled to the body, and a vertical stability roller coupled to the body, wherein the first track wheel, the second track wheel, and the vertical stability roller are arranged along a vertical line, wherein the first track wheel is located vertically above the second track wheel and the vertical stability roller is located between the first track wheel and the second track wheel.
