<p>PROBLEM TO BE SOLVED: To provide a hinge fitting having a new mechanism producible at a low cost with a small number of parts items, which can be entirely arranged within the thickness of a door, including a shaft core without being exposed to the outside and eliminate the clearance between the door and a frame, is never collided to the door body when opening the door to the maximum, and can facilitate the cutting work of the door or frame. SOLUTION: This hinge fitting comprises a sheet-like frame-side plate 1 and door-side plate 2, the frame-side plate 1 is provided with a protruding pin 3 and an elliptic hole 5, and the door-side plate 2 is provided with a protruding pin 4 and an elliptic hole 6. The pin 3 of the plate 1 and the pin 4 of the plate 2 are inserted to the elliptic hole 6 of the plate 2 and the elliptic hole 5 of the plate 1, respectively to assemble the plates 1 and 2 in the overlapped state. Such hinge fittings are arranged in two upper and lower positions to mount the door 18 on the flame. When the door 18 is opened, the two pins are moved in the two elliptic holes while keeping the mutually regulated states to provide the opening and closing operation of the door 18 moving on a specified locus in no contact with the frame 17.</p> |
