A framework structure adapted to be folded and stored in a collapsed state and erected in an expanded state on a support surface. The framework structure includes a support structure consisting of a number of legs, each having a firm upper mount with at least one pivot and a slidable lower mount with at least one other pivot, a peripheral structure of a number of scissors each having four rods connected in pairs between their ends by pivots and further connected in pairs at upper and lower end parts by upper and lower pivots, respectively, and a central structure having rods connected with the scissors at one or more of the pivot connections of the scissor rods. The upper and lower free end parts of the rods of each scissor are formed with a bore each engaging a pivot of the upper or lower mounts of a leg, respectively, whereby the pivot is attached to the mount with means having a clearance to the rod and the rod end part is axially fixed to the pivot. The framework structure is very suitable for canopies where the cylindrical contact surfaces between the scissor rod ends and the associated pivots ensure against lateral and torsional deflection of the scissors when the canopy is loaded by e.g. wind or snow.

A framework structure which is adapted to be folded and stored in a collapsed state and erected in an expanded state on a support surface, comprising
An assembling of an end part of a rod to a pivot on a mount of a framework structure, comprising
A method for connecting a pipe-formed end part of a rod to a pivot, which forms part of a U-formed clamp and is formed with at least one annular slot, by means of an elastic adapter formed with a bore for engaging the pivot and at least one key in the bore for engaging the annular slot and which furthermore is split into two halves by a slit extending from the bore to an end face of an end part of the adapter, comprising
A method for connecting the end part of a rod to a pivot, which forms part of an L-formed hook and is formed with an annular slot at either side of an end part, comprising
