Abstract: An adjustable hinge includes a first arm having a pivot pin rigidly mounted thereto and extending to one side thereof along an axis with a bearing element mounted on the other side of the arm. A second arm is mounted on the bearing element and includes an arcuate toothed rack coaxially aligned with the axis. An arm retention plate overlies the second arm for retention thereof on the bearing element and additionally entraps a toothed locking pawl which is mounted within the bearing element for selective radial movement into and out of engagement with the arcuate rack. The pawl is provided an arcuate slot therethrough which has one end thereof closer to the pivot pin than the second end. A pawl actuating device is pivotally mounted on the pivot pin and includes a pawl locating pin displaced from the axis to extend through the arcuate slot of the locking pawl. Additionally, the pawl locating pin extends through aligned slots in the first arm and the arm retention plate to provide support at opposite sides of the arcuate slot of the pawl during movement of the actuating device which produces the desired radial movement of the pawl.
