Abstract

A multi-position adjustable door hinge is comprised of a frame leaf having a lower barrel section and a door leaf having an upper barrel section. An eccentric pivot pin is disposed in axial rotational fit in a through bore of the lower barrel section and is in contact at a lower end with an adjustment screw. The eccentric pivot pin has an upper cylindrical portion eccentrically displaced from the lower cylindrical portion and extends into a cylindrical bore of an eccentric compensator cylinder adjustably retained in the through bore of the upper barrel section. The eccentric pivot pin and the eccentric compensator cylinder are both axially displaceable from one another whereby to impart relative lateral displacement thereof and of the barrels to a desired position. The adjustment screw at the bottom of the lower barrel section provides vertical adjustment between the frame leaf and the door leaf. Set screws are provided to lock the eccentric pivot pin and the eccentric compensator cylinder at the desired position.

A multi-position adjustable door hinge comprising a frame leaf having a lower barrel section and a door leaf having an upper barrel section, said lower and upper barrel sections having through bores of circular cross-section, said through bore of said lower barrel section having a threaded lower end portion receiving a vertical axis adjustment screw in threaded engagement therewith, an eccentric pivot pin having a lower cylindrical portion dimensioned for close 360° axial rotational fit in said through bore of said lower barrel section and having a lower end in contact with said adjustment screw, said eccentric pivot pin having an upper cylindrical portion eccentrically displaced from said lower cylindrical portion and extending above said lower barrel section, said lower end having a tool engaging cavity therein receiving a tool to cause axial rotation of said eccentric pivot pin and thereby lateral displacement between said frame leaf and door leaf, said adjustment screw having tool engaging means to provide for axial rotational displacement thereof to cause said eccentric pivot pin to displace vertically in said through bore to provide vertical displacement between said frame leaf and door leaf, an eccentric compensator cylinder in said through bore of said upper barrel section and having an eccentric cylindrical bore in a lower end thereof for receiving said upper cylindrical portion of said eccentric pin in close rotational fit therein, said eccentric compensator cylinder having an upper tool engaging end permitting axial rotational displacement thereof about 360° whereby providing transversal displacement between said frame leaf and door leaf, and means to arrest said eccentric pivot pin and said eccentric compensator cylinder at a desired position;

said adjustable door hinge providing precise adjustment of said lateral displacement, said vertical displacement and said transversal displacement without dismantling said adjustable door hinge;
said frame leaf and door leaf having screw holes for securing same to a door frame and a door.
