Abstract

A hinge for joining two adjacent panels. The hinge comprises a first piece adapted to receive a first panel, a second piece adapted to receive a second panel, and a middle piece. Each of the first and second pieces has an opening for receiving a panel and a socket defined between two spaced stopping surfaces. Portions of the middle piece are received within the sockets of the first and second hinge pieces. The configuration of the hinge pieces prevents the panels from folding in one direction while enabling the panels to fold together in the other direction.

Claims

1. A hinge for joining two panels of a door, said hinge comprising:

a first piece adapted to receive a first panel, said first piece having a socket defined between two spaced stopping surfaces,

a second piece adapted to receive a second panel, said second piece having a socket defined between two spaced stopping surfaces, and

a middle piece having a pair of cylindrical sections at outer ends of arms extending outwardly from a central section of said middle piece, one of said cylindrical sections being received within said socket of said first piece and the other of said cylindrical sections being received within said socket of said second piece wherein interengagement of said stopping surfaces of said first and second pieces of said hinge with said middle piece of said hinge prevents said door panels from folding in one direction while enabling said door panels to fold together in the other direction.

2. The hinge of claim 1 wherein said hinge is aluminum.

3. The hinge of claim 1 wherein said hinge is extruded.

4. The hinge of claim 1 wherein said middle piece of said hinge may be removed and rotated 180 degrees causing said door panels to only fold in an opposite direction than the direction set forth in claim 1.

5. A hinge for joining two adjacent door panels, said hinge comprising:

a first piece adapted to receive a first door panel, said first piece having an opening for receiving said first door panel and a socket defined between two spaced stopping surfaces,

a second piece adapted to receive a second panel, said second piece having an opening for receiving said second panel and a socket defined between two spaced planar stopping surfaces, and

a middle piece having a pair of cylindrical sections at outer ends of arms extending outwardly from a central section of said middle piece, one of said cylindrical sections being received within said socket of said first piece and the other of said cylindrical sections being received within said socket of said second piece wherein said one of said stopping surfaces of said first and second pieces of said hinge abuts an outer surface of said arms of said middle piece of said hinge when said panels are generally parallel preventing said door panels from folding in one direction while enabling said door panels to fold in the other direction.

6. The hinge of claim 5 wherein said hinge pieces are made of extruded aluminum.

7. The hinge of claim 5 wherein one of said stopping surfaces of said first and second pieces of said hinge abuts an inner surface of said arms of said middle piece of said hinge when said panels are folded together.
