Abstract:
A roll-up overhead door assembly which is selectively moved up and down to open and close an opening, the assembly having an open position, a closed position and a predetermined cleaning position, the assembly comprising:a drum positioned proximate the top of the opening and being rotatable between the open position, closed position and predetermined cleaning position; a flexible non-segmented unitary door panel which blocks substantially the entire opening when the door assembly is in the closed position; and, a hingeable connector for connecting the door panel to the drum, the hingeable connector being interposed between the panel and the drum, the hingeable connector having a first portion, an opposed second portion and an intermediate pivot point disposed between the first and second portions, the second portion of the hingeable connector being pivotable at the intermediate pivot point relative to the first portion of the hingeable connector, the panel being attached to the first portion of the hingeable connector and the drum being attached to the second portion of the hingeable connector, wherein when the drum is rotated toward the cleaning position the hingeable connector pivots independent of the rotation of the drum to allow the door panel to pivot away from the drum and wherein when the drum reaches the cleaning position no portion of the panel is in contact with the drum and no portion of the panel is in contact with the second portion of the hingeable connector.
