Abstract: Picture frame components include frame sections each having a channel and communicating cavity that are open at the rear of the frame. At least a region of each frame section adjacent the cavity is deformable and defines a deformable bearing surface. At each frame corner a bracket is provided to hold two adjoining frame sections together. The bracket has two legs with an engaging member on each leg that presents an engaging wall for being received in the frame section cavity and for engaging the deformable region of the frame section. Either the engaging wall or bearing surface, or both, are angled relative to the frame section length. The bracket is inserted in the channels of the adjoining frame sections and each frame section bearing surface is deformed by the engaging wall as the frame sections are forced tightly together.

Abstract: Components are provided for forming a picture frame which include frame sections adapted to be oriented at an angle to form a corner of the frame at adjacent ends of the sections. A bracket is provided for each corner and has a first leg and a second leg. One leg is disposed within a channel formed in one of the frame sections at the corner and the other leg is disposed within a channel of the other of the two frame sections at the frame corner. At least one of the legs of each bracket has a slanting engagement surface. A screw is threadingly engaged with one of the frame sections and also engages the bracket slanting engagement surface to urge the bracket leg along the frame section in which it is disposed in a direction away from the other frame section at the corner to draw the facing regions of the two frame sections together at the corner.
