ABSTRACT:
A novel picture frame is provided herein. The picture frame is made up of a plurality of unitary members having identically shaped cross-sections and joined end-to-end to enclose a predetermined area. Each of the members has, in cross-section, a channel having a base, a pair of opposed side walls and a pair of inwardly directed flanges to define an open face and a slot to receive a material to be displayed in the area. The picture frame includes an L-shaped locking bracket within the channel. The locking bracket is of generally rectangular, hollow, cross-section, having an upper roof, a pair of opposed side walls and a split base, the split base having mutually opposed beveled edges. One or more internally threaded holes are provided in the roof with a set screw provided in each one. When the set screw is tightened, it engages the split base and forces selected portions at the opposed side walls of the locking bracket against the corresponding opposed side walls of the channel.
