Abstract
Abstract This glassless mirror comprises a frame having grooves at its outer sides receiving a reflective sheet held in stretched condition by a flexible strip pressing the sheet into the grooves. The frame may be made of one extrusion having milled out or mitered corner angles to allow bending the extrusion into polygonal shape. A spring clip retains the meeting ends of the frame in alignment. The flexible strip is so shaped that it can easily be pressed into the groove and allowed to expand to hold the sheet in the groove.
