Patent ID: 7162774

Claim:
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.
