Abstract
A vertically adjustable hinge which permits easy, small and precise vertical adjustments. The hinge includes a body, a first leaf and a second leaf. It should be noted that the hinge may be provided only as a body and a first leaf for retro-fitting on to an existing second leaf. The body includes a leaf cavity, an adjustment mechanism cavity and, where necessary, a window. The window extends from a face side of the body and communicates with the adjustment mechanism cavity. The adjustment mechanism cavity communicates with the leaf cavity. The leaf cavity is sized and dimensioned to receive a planer portion of the first leaf therein with additional space for vertical adjustment of the first leaf. An adjustment mechanism is provided in the form of an elongated jack screw having a head which engages a slot formed in the first leaf and a threaded portion which engages a fixed thread. In another embodiment the adjustment mechanism is arranged with the head engaged with the body and the fixed thread disposed relative to the first leaf. In both embodiments, the adjustment mechanism is disposed in the adjustment mechanism cavity. A drive portion is provided on the adjustment mechanism of both embodiments to allow rotary movement of the adjustment mechanism to produce vertical displacement thereof.
