Abstract
A vertically adjustable hinge is disclosed. The hinge comprises a housing for attachment to a first structure. The housing has a housing cavity and an opening into the cavity. The cavity has an upper portion, a lower portion and a retaining portion forming a channel defining the upper portion and the lower portion. The hinge further includes a first leaf extending through the cavity opening and into the cavity upper portion, threaded nut rotationally fixed to the first leaf, and an adjustment mechanism disposed in the housing cavity. The adjustment mechanism comprises a jack screw extending between the upper cavity portion and the lower cavity portion. The jack screw has a threaded portion threadably engaging the nut in the upper cavity portion and a geared portion disposed in the cavity lower portion. The hinge further includes a worm gear engaging the jack screw geared portion, wherein rotation of the worm gear rotates the jack screw threaded portion in the nut, thereby moving the first leaf relative to the housing.
