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.

A kit for pivotally mounting a gate to a support post, said gate, with which the kit is to be used, having a gate leg with at least one aperture there through and at least one cross bar oriented substantially orthogonal to said support post with which the gate leg is to be used, and said kit having two generally vertically spaced apertures extending therethrough, said kit comprising:
- a first hinge assembly comprising an elongated shaft member and a mounting element pivotally, connected together to form a first pivot, said first pivot comprising a hinge pin mounted on the elongated shaft member of said first hinge assembly and a bushing for receiving said hinge pin mounted on the mounting element of said first hinge assembly, said hinge pin defining a first axis, said shaft member having external threads along the length thereof, said first hinge assembly including a pair of internally threaded nuts mountable on the threaded portion of said shaft member at adjustable positions along the length thereof for securing said shaft member in the aperture of said support post in a longitudinally adjustable manner by abutting a nut on said shaft member against the exterior of said support post at each end of said aperture, and
- a second hinge assembly comprising a pair of elongated rod members pivotally connected together to form a second pivot, said second pivot comprising a hinge pin mounted on one of said rod members and a bushing for receiving said hinge pin mounted on the other of said rod members, said hinge pin defining a second axis, each of said rod members having external threads along a portion of the length thereof, said pair of elongated rod members comprising a first rod member and a second rod member, said second hinge assembly including a pair of internally threaded nuts for mounting on the threaded portion of said first rod member at adjustable positions along the length thereof for securing said first rod member in an aperture of said support post in a longitudinally adjustable manner by abutting a nut on said first rod member against the exterior of said support post at each end of the aperture through said support post, said second hinge assembly including a second pair of internally threaded nuts for counting on the threaded portion of said second rod member at adjustable positions along the length thereof such that said second rod member is adjustably longitudinally securable in an aperture of said gate leg by abutting a nut on said second rod member against the exterior of said gate leg at each end of said aperture, whereby the distance between the second axis and the gate leg and the distance between the second axis and the support post are both adjustable to place the gate in a level orientation at multiple locations along the swing of the gate;
- said first and second axes are parallel to each other;
- and
- wherein the distance between the second axis of the second hinge assembly and the gate post may be adjusted independent of the distance between the first axis of the first hinge assembly and the gate post such that the distance between the gate leg and one of said first and second axes can be adjusted without changing the distance between the gate leg and the other of said first and second axes.

In combination
- a gate having a proximate end including a gate leg with an aperture therethrough, at least one crossbar oriented transverse to said gate leg, and a remote end;
- a support post proximate to said gate leg, said support post having two spaced apertures therethrough, said apertures comprising an upper and a lower aperture;
- a first hinge assembly pivotally connecting said gate and said support post, said first hinge assembly including an elongated shaft member and a mounting element pivotally connected together at a first pivot, said shaft member having external threads along a portion of the length thereof, said first hinge assembly including a pair of internally threaded nuts, said shaft member extending through the upper aperture of said support post and having a nut threadedly mounted on the threaded portion of said shaft member in abutment against an exterior of said support post at each end of the upper aperture therein to permit longitudinal adjustment of said shaft member in the upper aperture to thereby permit adjustment of the distance between the first pivot and said gate leg;
- and
- a second hinge assembly pivotally connecting said gate and said support post, said second hinge assembly including a pair of elongated rod members pivotally connected together at a second pivot, each of said rod members having external threads along a portion of the length thereof, said pair of elongated rod members comprising a first rod member and a second rod member;
- said second hinge assembly including a pair of internally threaded nuts, wherein said first rod member extends through the lower aperture of said support post and has a nut threadedly mounted on the threaded portion of said first rod member in abutment against an exterior of said support post at each end of the lower aperture therein to permit longitudinal adjustment of the position of said first rod member in the lower aperture to thereby permit adjustment of the distance between the second pivot and the support post;
- said second hinge assembly including a second pair of internally threaded nuts, wherein said second rod member extends through the aperture of said gate leg and has a nut threadedly mounted on the threaded portion of said second rod member in abutment against an exterior of said gate leg at each end of the aperture therein to permit longitudinal adjustment of the position of said second rod member in said aperture to thereby permit adjustment of the distance between the second pivot and said gate leg;
- whereby the distance between the second pivot and the gate leg and the distance between the second pivot and the support post are both adjustable to place the gate in a level orientation at multiple locations along the swing of the gate;
- said first and second axes are parallel to other;
- and
- wherein the second pivot of the second hinge assembly is positionable independent of the position of the first pivot of the first hinge assembly such that the respective distances between the gate leg and said first and second pivots can be varied with respect to each other.
