  • Patent number: 6073396
    Abstract: A gate hinge is provided which enables a gate to be maintained upright and level in a first closed position and to clear obstacles or follow the contour of the ground when swung into a second position. The gate hinge hereof can be used in combination with a support post, a gate and a conventional hinge. The gate hinge includes a hinge pin preferably mounted on a threaded rod and a bearing attached to a second rod. One of the rods is attached to the support post, the other rod is attached by mounting brackets to the gate. The pivot axis of the hinge is offset relative to the pivot axis of the other hinge, so that during swinging of the gate, its angle of inclination relative to the support post changes.
