Abstract: An adjustable locking hinge for holding a door either completely or partially open. The adjustable locking hinge has an adjustable friction resistance and allows retention of the door at any desired angle. The hinge includes two hinge leaves with knuckles in an intermeshing relationship with each other, and a hinge pin that extends through the knuckles that is axially shiftable to locked and unlocked positions. Two pins extend upwardly from opposite sides of a base element and engage a sprocket plate mounted on the hinge pin, in the locked position. In the locked position, the resistance to move the door is adjusted by an actuating mechanism. A protective cap is removably attached to the base element, and covers the components of the locking mechanism. The protective cap has a central aperture through which the top portion of the actuating mechanism extends. The lower portion of the hinge pin includes an axial bore with an end button press fit therein.

Abstract: A locking hinge assembly includes two butt plates or hinge leaves each having a plurality of interlocking knuckles with an axially shiftable hinge pin mating with the knuckles. A locking mechanism carried by the top of the hinge pin includes pressure and sprocket plates, with one plate keyed to the hinge pin and spring devices adjustably compressible to apply varying degrees of biasing force against the movement of one hinge leaf relative the other hinge leaf. This is accomplished due to the juncture of one hinge leaf to the sprocket plate while the keyed pressure plate is fixed relative the other hinge plate.
