Abstract
An adjustable, lift-off hinge having a hinge assembly including a first hinge member and a second hinge member joined by a tension pin along a vertical rotational axis. Advantageously, the hinge has two identical hinge members enabling manufacturing with a single mold or tooling set. The present invention allows low friction, pivotal movement of the first hinge member relative to the second hinge member about the vertical rotational axis. The hinge also includes a vertical adjustment mechanism allowing for precise movement of the first hinge member relative to the second hinge member along the vertical axis and precise movement of the second hinge member relative to the first hinge member along the vertical axis.
Claims16
A vertically adjustable hinge for pivotally mounting a door or other object to a frame or other structure, comprising:
- a pair of identical hinge members, here designated as first and second hinge members, each incorporating a base plate and a hinge sleeve;
- a tension pin with a first and second end, said second end of said tension pin being insertable through the top of the hinge sleeve of said first hinge member and extending into the top of the hinge sleeve of said second hinge member, the tension pin defining a vertical rotational axis;
- a vertical adjustment cylinder insertable into the hinge sleeve of said second hinge member;
- whereby altering the position of said vertical adjustment cylinder within the hinge sleeve of said second hinge member alters the position of said second hinge member relative to the position of said first hinge member along said vertical rotational axis.
