When the opposite end parts of the coupling members are press-fitted in the hollow coupling parts of the members to be coupled, the crests of concave parts of the angle shape concavities and convexities are corrupted by the opposed surface so as to be made into close contact with and firmly coupled to the associated surface, thereby it is possible to surely couple a pair of members to be coupled with a simple work.

Abstract: An extruded longitudinally-pliable but uprightly rigid plastic edging strip may be affixed to the side of the outer edge of a shaped back mounting panel. The tall thin cross section of the planar strip allows its longitudinal axis to bend sideways to follow the curved edge of the shaped backing. Once in place, canvas or like fabric may be stretched over the edging strip and lie in a horizontal plane that is vertically elevated from the horizontal plane of the backing panel, whereupon the canvas will not contact the backing panel. Suitably shaped injection-molded thrust-support brackets placed at spaced horizontal intervals help stiffen the edging strip against the inwardly directed force of the stretched canvas. Alternately, the cross-section of the edging strip can be extruded in a shape which inherently resists inward deformation, so that the need for separate brackets is eliminated.
