Supporting framework for a shelter shed

Claim 1

In a shelter shed supporting framework of the type including a plurality of support arches each made up of a plurality of arch elements with the ends positioned in adjacency for interconnection with one another and with traverse beams interconnecting the arches at predetermined distances apart; the provision of spaced pairs of articulated point means at adjacent ends of the arch elements and beams for interconnecting the same and comprising double brackets arranged in spaced pairs at the ends of adjacent arch elements with one double bracket in substantial alignment with the outer edge of its associated arch element and with the other double bracket in substantial alignment with the inner edge of its associated arch element and with coaxial holes through the brackets of each pair; tube-like elements carried at opposite ends of each beam and being parallel to one another and of a length corresponding to the distance between adjacent brackets of each double bracket and fitting therebetween with the openings through the tube-like elements in coaxial alignment with respective pairs of holes in the brackets; and fastening pins extending through aligned bracket holes and tube-like elements for connecting the arch elements and transverse beams at the joint means; the axes of the holes through the spaced brackets of each pair being parallel with the radius of curvature of the support arch whereby successive arch elements can be pivoted side-by-side about the axis of either spaced brackets when the pin through the other spaced brackets is removed.
