Compact adjustable hinge
View Patent ↗The invention disclosed provides a compact hinge capable of a vertical, a horizontal, and an overlay adjustment, comprised of a cup portion and a hinge arm with one end pivotably connected to the cup portion and the other end slideably connected to a fastener plate. The fastener plate further comprises a first semi-planar surface for contact with a cabinet frame and a second semi-planar surface for slideable engagement with the hinge arm to accomplish the horizontal adjustment. The first and second semi-planar surfaces are interconnected by a deformable hinge section that allows for an elastically resilient connection at one end and an adjusting screw at the other end for a horizontally arcing movement relative to each resulting in an overlay adjustment. The fastener plate further comprises an elongated aperture in the first semi-planar surface through which the vertical adjustment is accomplished.
