1. Components for constructing a picture frame, said components comprising:

  • a plurality of frame sections for being assembled into a picture frame in which two of said frame sections are adapted to be oriented at an angle to form a corner of the assembled frame at the adjacent ends of the two sections, each said frame section having an end portion at each end containing material that is deformable under the imposition of a localized force, each said frame section end portion defining a channel opening rearwardly when the frame section is assembled with the other frame sections to form the frame, said channel extending from the end of said frame section along said frame section end portion, each said frame section end portion further defining a cavity communicating with said channel and an adjacent deformable bearing surface comprising said deformable material; and

    a bracket adapted to be disposed within the channels of said two frame sections when oriented to form a corner of the assembled frame, said bracket having two legs disposed at an angle substantially identical to the angle formed by said two frame sections at said frame corner, each said bracket leg having a first portion adapted to be received in one of said frame section channels, each said bracket leg having a second portion with an engaging member for being received in one of said frame section cavities, said engaging member defining an engaging wall to engage said frame section deformable bearing surface, said frame section bearing surface and said bracket engaging wall being oriented at angles relative to the length of the frame section whereby, when the bracket legs are aligned in registry with the channels of said two frame sections disposed to form the corner of the assembled frame, relative movement between the bracket and the frame sections can be effected to dispose the bracket within the channels and to cause the engaging wall of each bracket leg to deform the associated frame section bearing surface and force the two frame sections together at the corner.
