Abstract: The retainer clip is adapted to be positioned between an inwardly extending flange at the back of a picture frame and backing material located within the frame behind a picture in the frame. The retainer clip includes a resilient body, structure on the body for engaging the inwardly extending flange at the rear edge of the picture frame and structure on the body for engaging the backing material. The structure for engaging the backing material includes at least one prong, detent or barb positioned to engage the backing material.

Abstract: A multi-piece back loading framing system is disclosed. Each frame member has bevelled ends for forming mitered joints, a front face and side portion. The frame sections have a first hardware receiving channel directly below the front face and a second hardware receiving channel adjacent the side portion. The frame sections may be joined at mitered joints using an L-shaped screw corner key in the first channel or an L-shaped crimp corner key bracket in the second channel.

Abstract: A tension panel includes a frame, and a retaining device affixed to and retaining respective corners of a display sheet. A stretching and fixing assembly is provided which includes an L-shaped bar formed by two legs joined together to define a bent region of the bar. The legs each have a free end attached to the frame so that the bar is movable from a raised position, through an intermediate position, to a lowered position in which the bar lies essentially flush with the frame. The assembly further includes a resilient member having one end attached to the bent region of the bar, and another end attached to the retaining device for exerting a tensile force on the retaining device when the bar is in the lowered position. The tensile force extends in a direction along an imaginary line that divides an interior angle of the respective corner into two angles, so as to stretch and fix the display sheet on the frame. When the bar is in the raised position, the tensile force is not exerted.
