An upward acting sectional door is formed of rectangular door sections which are interconnected to each other by a continuous hinge comprising opposed partial arcuate hinge members formed on a lower rail of an upper section and an upper rail of an adjacent lower section and engaged with a third hinge member comprising an elongated tubular pin having a D-shaped cross section. The hinge pin is secured against rotation by retainer members at opposite ends of one of the door sections. The hinge permits lateral assembly and disassembly of one door section relative to the other. Additional load bearing hinge members are provided connected to the lateral side edges of adjacent door sections and are interconnected by support members disposed in the tubular hinge pin for transferring part or all of the forces between adjacent door sections thereby allowing the arcuate hinge members to function substantially as cooperating light and weatherseal members and to provide a substantially pinch proof door.
A sectional door comprising a plurality of generally planar door sections hingedly connected to each other by hinge means between adjacent sections wherein at least two adjacent sections are connected by a hinge comprising a first hinge member connected to one of said sections, said first hinge member including a partial arcuate bearing portion delimited by a first gap, a second hinge member connected to the other of said sections, said second hinge member including a partial arcuate bearing portion delimited by a second gap, said partial arcuate bearing portion of said first hinge member being insertable in a space formed by said partial arcuate bearing portion of said second hinge member laterally with respect to a hinge axis of said hinge for operably connecting said first and second hinge members to each other, and a third hinge member disposed in a space formed by said partial arcuate bearing portion of one of said first and second hinge members and rotatable between a first position to permit lateral insertion of said partial arcuate bearing portion of said first hinge member in said space formed by said partial arcuate bearing portion of said second hinge member and a second position upon connection of said first and second hinge members to each other to retain said first hinge member connected to said second hinge member.
A hinge assembly for connecting a first structural member to a second structural member, said hinge assembly comprising:
In a sectional door comprising a plurality of generally planar door sections hingedly connected to each other by hinge means between adjacent sections, said hinge means comprising:
In a sectional door comprising a plurality of interconnected door sections, a hinge for connecting adjacent ones of said door sections to each other comprising opposed first hinge members connected to one of said door sections, at opposed side edges of said one door section, respectively, opposed second hinge members connected to the other of said door sections at opposed side edges of said other door section, respectively, and hinge pin means, respectively, at opposite ends of said door sections forming a pivot connection between respective ones of said first hinge members connected to said one door section and said second hinge members connected to said other door section for transferring forces between said door sections, arcuate members disposed on each of said door sections extending between said hinge members and extending in overlapping relationship to each other to form at least one of a weather seal and light seal between said door sections when said door sections are pivoted relative to each other;
A sectional door comprising a plurality of generally planar door sections hingedly connected to each other by hinge means between adjacent sections wherein at least two adjacent sections are connected by a hinge comprising a first hinge member connected to one of said sections and comprising a partial arcuate bearing member engageable with a cooperating bearing surface on the other of said sections, a second hinge member connected to the other of said sections and including a partial arcuate bearing member engageable with a bearing surface on said one section and a third hinge member operable to be releasably connected to one of said sections, said third hinge member is engageable with at least one of said first and second hinge members, respectively, to provide for pivotal movement of one of said sections relative to the other of said sections, said hinge members being operable to provide for pivotal movement of one of said sections with respect to the other of said sections about a hinge axis and said hinge being further operable to be assembled and disassembled by moving said section laterally with respect to each other and said axis, a retainer member engageable with said third hinge member and operable to be secured to one of said door sections for positioning said third hinge member in a fixed position with respect to said one section, said retainer member comprising an elongated hub portion insertable within a bore in one end of said third hinge member, said retainer member including a transversely extending arm portion engageable with a side edge of said one section for securing said retainer member and said third hinge member against rotation relative to said one section, a support member insertable within said bore of said third hinge member in an end of said third hinge member opposite said one end and a retainer arm operable to be connected to an opposite side edge of said one section for retaining said support member in said bore of said third hinge member.
In a sectional door comprising a plurality of generally planar door sections hingedly connected to each other by hinge means between adjacent sections, said hinge means comprising:
