Abstract
Abstract A hinged building truss, such as a roof truss, includes elongated wooden structural members connected by a double hinge joint. The joint has a central elongated flat plate having first and second pivots located toward respective ends of the elongated plate. First ends of first and second flat plates overlap first and second ends of the central flat plate and rotate in the plane of the plates at the first and second pivots, respectively. The first and second plates each include a plurality of teeth, struck from second end areas of each plate, for fastening each plate to a face of a structural member to be pivoted. The structural members can thus be rotated about the pivots. The length of the elongated plate between the overlapping portions of the first and second plates is sufficient to accommodate sheet sheathing attached to each of the structural members when the double hinged joint is in folded position with the structural members substantially parallel and adjacent to each other.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
210 words
A double hinged joint for joining frame members of a hinged truss, each member having a sheet of sheathing attached thereto, used in building construction, comprising: an elongated flat plate comprising first and second pivots substantially adjacent first and second ends of said elongated plate, respectively; first and second flat plate members pivoted at said first and second pivots, respectively; wherein a first end of said first plate member overlaps and is pivoted at said first end of said elongated plate, and a first end of said second plate overlaps and is pivoted at said second end of said elongated plate, and said first and second plate members rotate about said pivots in the plane of said elongated plate; and wherein the distance between said first ends of said first and second plate members is equal to at least the thickness of two sheets of the sheet sheathing; whereby said first plate member is attached to a first structural member having sheet sheathing attached thereto and said second plate member is attached to a second structural member having sheet sheathing attached thereto and said sheet sheathing is accommodated by the length of the elongated flat plate when said first and second structural members are folded substantially parallel to each other.
Claim 2
Dependent Claim
210 words
A double hinged joint for joining frame members of a hinged truss, each member having a sheet of sheathing attached thereto, used in building construction, comprising: an elongated flat plate comprising first and second pivots substantially adjacent first and second ends of said elongated plate, respectively; first and second flat plate members pivoted at said first and second pivots, respectively; wherein a first end of said first plate member overlaps and is pivoted at said first end of said elongated plate, and a first end of said second plate overlaps and is pivoted at said second end of said elongated plate, and said first and second plate members rotate about said pivots in the plane of said elongated plate; and wherein the distance between said first ends of said first and second plate members is equal to at least the thickness of two sheets of the sheet sheathing; whereby said first plate member is attached to a first structural member having sheet sheathing attached thereto and said second plate member is attached to a second structural member having sheet sheathing attached thereto and said sheet sheathing is accommodated by the length of the elongated flat plate when said first and second structural members are folded substantially parallel to each other.
Claim 3
Dependent Claim
25 words
