Abstract

A corner connection fitting (1) for a frame is disclosed. The corner connection fitting (1) interconnects front frame members (18) to base frame members (13). The front frame members (18) are rotatable to an outer, open position so as to allow the picture (21) to be easily inserted or adjusted within the frame assembly.

Claims

1. A corner connection fitting for a frame, the frame being of the type having a front frame member and a base frame member, said corner connection fitting comprising:

a bottom part and a side part interconnected by hinge means so that said bottom part and side part are movable between a first, closed position and a second, open position, wherein said front frame member is interconnected to said side part so that rotatable movement of said side part causes movement of said front frame member;

means for biasing said bottom part and side part toward its first, closed position, wherein said biasing means includes a plate spring;

first connection means for interconnecting said corner connection fitting to said front frame member; and

second connection means for interconnecting said corner connection fitting to said base frame member.

2. The corner connection fitting according to claim 1, wherein said corner connection fitting is made of synthetic resin material.

3. A corner connection fitting for a frame, the frame being of the type having a front frame member and a base frame member, said corner connection fitting comprising:

a bottom part and a side part interconnected by hinge means so that said bottom part and side part are rotatable with respect to each other between a first, closed position and a second, open position;

a plate spring which biases said bottom part and said side part toward its first, closed position;

said side part having a frame guide which is slidably interconnected to a corresponding frame guide groove formed in said front frame member, wherein rotatable movement of said side part causes movement of said front frame member; and

said bottom part having a base guide which is slidably interconnected to a corresponding base guide groove formed in said base frame member,

wherein said corner connection fitting is substantially L-shaped.

4. The corner connection fitting according to claim 3, wherein said corner connection fitting is made of synthetic resin material.

5. The corner connection fitting according to claim 3, wherein said corner connection fitting further includes a corner hook which is engagable with a base stopper on said base frame member when said corner connection fitting is in its second open position.

6. The corner connection fitting according to claim 3, wherein said corner connection fitting is L-shaped.
