Abstract:
A sectional upward acting door including interconnected door panels, said panels comprising generally planar rectangular members each having a generally planar outer wall part and generally planar inner wall parts spaced from said outer wall part, an elongated upper edge of said panel including an upwardly projecting convex surface extending at an angle with respect to said outer wall part and including a curvilinear portion adjacent to and contiguous with a generally planar wall portion, and an inclined wall part extending from said generally planar wall portion, an elongated lower edge of said panel including a tip portion contiguous with said outer wall part, a concave part of said lower edge and a further inclined wall part extending from said concave part, said upper and lower edges being cooperable with each other between adjacent interconnected panels to form a pinch resistant joint when said adjacent panels are pivoted relative to each other, andplural hinge assemblies spaced apart along and interconnecting adjacent ones of said panels, said hinge assemblies including opposed hinge plates which are operable to engage upon moving adjacent panels toward each other to thereby pivotably connect said adjacent panels, said hinge plates being connected by fasteners to said inclined wall part of one panel adjacent its upper edge and said inclined wall part adjacent said lower edge of an adjacent panel, respectively, whereby said hinge assemblies are disposed substantially entirely between said outer wall part and said inner wall parts of said panels, respectively, and form a pivot connection between adjacent panels.
