A door apparatus for closing an access opening and to a parking apparatus equipped therewith. The door apparatus has two vertically aligned guide rails and an inner and an outer door element which are each movably mounted in/on a vertically aligned inner or outer guide of the guide rails. In a closed position, the inner door element is arranged in a first region of the access opening which is situated lower than a second region in which the outer door element is arranged. In an open position, the inner and the outer door element are arranged in a third region of the access opening which is situated higher than the first and the second region. Furthermore, the door apparatus has a locking element and a coupling element.

In an example an overhead door track is provided. The overhead door track includes a vertical track section having an opening to receive a roller of a panel of an overhead door and to guide movement of the roller within the opening and a single solid polymer based vibration isolator coupled to the vertical track section to reduce vibration of the vertical track section caused by movement of the roller within the opening.

An emergency bi-fold door closing prevention system includes a building having an access opening with an upper edge. A bi-fold door is hingedly mounted to the building wall and includes a plurality of panels each being laterally elongated. The plurality of panels includes a bottom panel having a bottom edge that is positionable adjacent to a floor surface to define a closed position. A safety line assembly is attached to and extends between the building wall adjacent to the upper edge and the bi-fold door adjacent to the bottom edge. The safety line has an extendable length. The length of the safety line assembly extends when the bi-fold door moves toward the closed position below a threshold velocity. The length of the safety line assembly is inhibited from extending when the bi-fold door moves toward the closed position above the threshold velocity to prevent unimpeded falling of the bi-fold door.

Examples of the present disclosure provide an overhead door panel. The overhead door panel includes a pair of parallel glass panes, a metal frame with parallel lateral stiles oriented perpendicular to the pair of parallel glass panes, a first seal system located at a first lateral stile, and a second seal system located at a second lateral stile, wherein the first seal system and the second seal system engage with at least one glass pane of the pair of parallel glass panes and a lateral stile of the parallel lateral stiles of the metal frame such that the first seal system and the second seal system are between the at least one glass pane and the lateral stile.

A package delivery door assembly is configured for being installed in an opening in a garage door. The assembly includes a frame having an outer peripheral planar portion configured to directly contact an outer surface of the garage door when the assembly is installed, and an inwardly extending flange portion configured to extend into the opening in the garage door when the assembly is installed. The assembly further includes two (or more) inner brackets. Each inner bracket has an inner planar portion and a ledge perpendicular to the inner planar portion. The ledges of the at least two inner brackets are configured to be coupled to the inwardly extending flange portion of the frame when the door assembly is installed, thereby avoiding additional holes being cut into the garage door. The assembly further includes a package delivery door hingedly attached to the frame.

Disclosed is a sectional door adapted to withstand high wind load and impact from flying debris. The door includes a glazing bead to secure glazing panels into frames formed by the rails and stiles of the door. The bead is connected with the frame by engagement between extensions on the bead and respective lips along the edges of the frame. The bead is pressed against the frame, causing the extension to elastically flex to allow the extensions to fit between the lips. The extensions are received in gaps formed by the lips to secure the bead in place on the frame. Force on the door cause by high winds is communicated from the glazing panel through the bead and to the frame. The door also includes reinforcements arranged along the rails to communicate forces, such as high wind load forces, from the frame to the edges of the doorway surrounding the door. The reinforcements include endcaps that increase stiffness of the rails to prevent the rails from buckling during severe weather events.

A fastener system for securing a panel to a frame comprises one or more rotating fasteners installed in the perimeter edge of the panel. In operation, one or more cam surfaces of the fastener engage receiving surfaces of a receiver on the frame such that, upon rotation of each fastener, the panel is drawn toward the frame. In some embodiments, the panel is moved in a first direction parallel to the panel and a second direction perpendicular to the panel or in a composite diagonal direction inclined relative to the panel. The fastener system may facilitate compression of seals disposed along the perimeter edge of the panel and between a side of the panel and rabbet ledge of the frame and may further facilitate removal and maintenance of the panel.

A system is disclosed for converting an overhead door into a gate or serving window, the system having at least two rows of panels spanning the width of the door, one panel located above and adjacent to the other panel, a pair of rails opposite one another and adjacent to the panels, the panels traveling within the rails to move from a closed position to an open position, and at least one hinge connecting the lower row of panels to the upper row of panels, the hinge having an upper half attached to the upper row of panels and a lower half attached to the lower row of panels, the upper and lower halves of the hinge connected by a removable central pin, wherein the upper row of panels moves from the closed position to the open position when the central pin is removed from the hinge.

A cover for a garage door which includes a front portion adapted to cover a street facing surface of the garage door, and a pair of rear portions adapted to be arranged covering a garage facing surface of the garage door. The cover also includes at least four collars adapted to be arranged at corners of the garage door. Each collar defines a cutout extending inwardly from an edge of the cover to facilitate an extension of an associated corner of the garage door outside the cover, a first coupling portion extending along the rear portion from the cutout to a lateral edge of the cover, and a second coupling portion extending from the cutout in a direction opposite to the first coupling portion. The first coupling portion is adapted to engage with the second coupling portion.
