Ninety-degree Door Hinge

A door hinge which stops the swing-open motion of a door before it can strike an adjacent wall located at ninety degrees to the closed door.

US Patent Number: 6,353,967

By stopping the motion of the door at ninety degrees, the protruding hardware of the door will not penetrate or otherwise damage the adjacent wall. Frequent repairs are therefore avoided.

The door hinge is adaptable to various residential and commercial applications.

Hardware & Tools

Technical Details:

As can be readily seen from the drawing, the invention is a standard door hinge with certain modifications which limit the hinge to a maximum rotation of ninety degrees

The Drawing is an exploded isometric view of the invention. Referring to the drawing, the door element base plate 10 includes a plurality of cylindrical barrels 20 and 40 having an inside diameter of proper dimension to receive a hinge pin 110.

The upper cylindrical barrel 20 includes a tab 30 which extends downward along the vertical axis of the hinge. The lower cylindrical barrel 40 includes a tab 50 which extends upward along the vertical axis of the hinge. The door frame base plate 100 includes a plurality of cylindrical barrels 60 and 80 having an inside diameter of proper dimension to receive a hinge pin 110. The upper cylindrical barrel 60 includes a slot 70 opening upward along the vertical axis of the hinge. The lower cylindrical barrel 80 includes a slot 90 opening downward along the vertical axis of the hinge. The hinge is assembled by aligning tab 30 with slot 70 and likewise aligning tab 50 with slot 90. While maintaining the tabs and slots in their aligned positions, the relative position between the door base plate 10 and the door frame base plate 100 is adjusted so that the cylindrical barrels 20, 40, 60 and 80 are aligned along the vertical axis of the hinge. The width of slots 70 and 90 is sufficiently greater than the width of tabs 30 and 50 such that the door base plate 10 and the door frame base plate 100 can freely rotate with respect to one another through a maximum of ninety degrees. Further, the slots 70 and 90 and tabs 30 and 50 are keyed to allow the door base plate 10 and the door frame base plate 100 to rotate from a closed position to a ninety-degree open position.
