ABSTRACT:
A frame for covering the border area of a wall-mounted display, including a plurality of nails with first heads at the driven end of the nail and second heads axially displaced from the first heads. A resilient structure for supplying directional pressure, such as tension spring wires, is located between the two heads radially extending beyond the first heads when expanded. The nails are driven through the display with the second nail heads holding or mounting the display on the wall. Each of the frame strips includes apertures in its underside which are larger than the first nail heads but smaller than the tension spring wires, permitting such frame strips to pass over the first nail heads and the tension spring wires contracting the wires in the process. These tension spring wires expand to hold the frame in place by resilient action. Further, the frame may be adjustable, wherein the frame strips have telescoping pieces, matingly conforming ends, and/or corner plates to enhance the beauty and add rigidity to the structure of the frame.
