Picture frame

In a picture frame formed from frame sections, each of said frame sections having a rearwardly facing channel which terminates in inwardly extending lips, an improved means for securing an adjacent pair of said sections together at a corner junction comprising:

• a bracket having a pair of legs disposed at an angle substantially identical to the angle made by said frame sections at said corner junction, said legs being adapted to fit within the rearwardly facing channels of adjacent frame sections at said corner junction, said legs being of a width which is greater than the rearwardly facing opening defined by said lips of said rearwardly facing channels thereby to retain said bracket within said channels;
• locking means for urging said bracket away from the bottom of said channels and toward and against said lips;
• the cross-sectional shape of at least one frame section comprising said rearwardly facing channel being defined by a common web, a pair of rearwardly extending walls connected to the ends of said web, each of said rearwardly extending walls terminating at its rear edge in said inwardly extending lip, a forwardly extending wall portion connected to an end of said common web and extending forwardly therefrom, the forward end of said forwardly extending wall portion terminating in an inwardly extending forward lip, said forwardly extending wall portion, common web and inwardly extending forward lip defining a picture-receiving channel, said device further comprising:
• the surfaces of said common web, rearwardly extending walls and inwardly extending lips which define said rearwardly facing channel being arranged to define a parallelogram of a configuration which is displaced approximately 1/8.degree. to 1/2.degree. from the rectangular.

In a picture frame formed from mitered frame sections, each of the frame sections having a rearwardly facing channel which terminates in inwardly extending lips having interior surfaces, improved means for securing an adjacent pair of said sections together at a corner junction comprising:

• a bracket having a pair of legs disposed at an angle substantially identical to the angle made by the frame sections at the corner junction, the legs being received within the rearwardly facing channels of adjacent frame sections at the corner junction, the legs being of a width which is greater than the rearwardly facing opening defined by the lips of the rearwardly facing channels to retain the bracket within the channels;
• a bearing plate of generally identical configuration to that of the bracket, the bearing plate being disposed within said adjacent frame sections and lying within the channels forwardly of the bracket;
• and
• locking means for urging the bracket and bearing plate apart, said bracket, bearing plate, locking means, and the interior surfaces of said lips of said channels being constructed to cooperatively cause at least one of said adjacent frame sections to pivot along an axis parallel to its lenght to draw the forwardly facing regions of the adjacent frame sections together at the corner junction in response to operation of the locking means.
