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.
