Upward acting sectional door

An upward acting sectional door comprising, a plurality of door panels pivotally attached to each other, each panel having a front surface and a rear surface spaced from each other by an internal structure, the internal structure defining a plurality of encapsulated spaces between the front and rear surfaces which provide a thermal break therebetween, and a recess formed in said rear surface of said panel and an end stile fitting over an end of said panel, said end stile including a tab releasably received within said recess.

An upward acting sectional door comprising, a plurality of door panels pivotally attached to each other, each panel having a front surface and a rear surface spaced from each other by an internal structure, the internal structure defining a plurality of encapsulated spaces between the front and rear surfaces which provide a thermal break therebetween and a hinge pivotally connecting said plurality of door panels and a reinforcing member received within said hinge, said reinforcing member receiving a shaft of a roller assembly.

An upward acting sectional door comprising, a plurality of door panels pivotally attached to each other, each panel having a front surface and a rear surface spaced from each other by an internal structure, the internal structure defining a plurality of encapsulated spaces between the front and rear surfaces which provide a thermal break therebetween and a cladding covering the front surface of said panels, wherein said cladding is releasably attached to said panels by a pair of hooks, the first hook extending from the top of said cladding and the second hook extending from a bottom of the cladding and said panels have a flexible hinge interacting with said first hook and said second hook.

A sectional door having a plurality of panels joined by a hinge, the hinge comprising, a flexible double loop member extending between adjacent panels, said flexible member defining a first axis and a second axis about which said sections pivot, wherein at least one of said axes is moveable relative to said panels during operation of the door such that stresses within the hinge caused by articulation of the panels are relieved by pivoting about said axes and movement of at least one of said first and second axes.

A sectional door having a pair of opposed tracks for guiding door rollers between a closed position and an open position having a liner within the tracks comprising, an insert portion adapted to conform to the inner surface of the track for contacting the door rollers, a cover portion attached to the insert portion and bridging the space between the door and the tracks to prevent entry of foreign matter, and a sealing portion attached to the cover portion and extending to at least partially cover the door as a weather seal and to assist in stabilizing the door.

A pre-packaged upwardly acting sectional door system comprising, a pair of spaced track framers spanned by a header, a pair of tracks associated with said track framers, a door having a plurality of panels pivotally joined by hinge members, roller assemblies on said door received in said tracks, a counterbalance system attached to said header and operatively engaging said door, and an operator mounted on said header operatively interconnected with said counterbalance system and positioned to maintain said door in a closed position relative to said header, said track framers, said tracks, said door, said rollers, said counterbalance system and said operator being operatively assembled for transport and installation.

A pre-packaged, assembled upwardly acting sectional door system comprising, a pair of spaced track framers spanned by a header, a pair of tracks associated with said track framers, a door having a plurality of panels pivotally joined by hinge members, roller assemblies on said door received in said tracks, a counterbalance system attached to said header and operatively engaging said door, and an operator mounted on said header operatively interconnected with said counterbalance system and positioned to maintain said door in a closed position relative to said header and a motor pivotable between an operating position and a locked position, said motor being in a locked position adjacent the door.

An upwardly acting sectional door system comprising, a plurality of sections including a top section, the sections being mounted between a pair of tracks, including horizontal track sections, which guide the door between a closed and an open position, a roller assembly, having an arm pivotally attached to said top section at one end thereof, a wheel rotatably attached to said arm at the other end thereof, wherein said wheel fits within said tracks causing said arm to pivot from a position at an angle to said top section when the door is in the closed position to a position above and substantially in planar alignment with said top panel when the door moves toward the open position, whereby said top section never projects above said horizontal track section to eliminate the need for overhead clearance.

A sectional door comprising, first and second adjacent panels, a flexible double loop member having an inner leg and an outer leg joined by a curve return extending between said adjacent panels and attached to said first and second adjacent panels, a first hook attached to one of said first and second adjacent panels and interposed between said inner leg and said outer leg, said return curve movable about an axis located substantially centrally of said flexible double loop member during a portion of the articulation of said first and second panels and said outer leg and said hook movable about said return curve during a portion of the articulation of said first and second panels.
