Abstract

A hinge is provided which includes a frame-side base member 41 adapted to be attached to an open frame 10 and a door-side base member 42 adapted to be attached to a door 20. The frame-side base member 41 is connected to a first plate 31 and the door-side base member 42 is connected to a second plate 32 which is hinge connected to the first plate 31, for holding the door 20 so as to be capable of rotating. The second plate 32 is separable from the door-side base member 42. The door-side base member 42 is shaped to be symmetrical about the vertical center line of the door edge, and is imbedded in the edge of the door 20 without any protrusions from the door 20. Further, the door-side base member 42 is provided with a slit 44 which penetrates the member 42 in the width direction of the door 20 and into which the second plate 32 can be inserted from both the front and back sides of the door 20. There is also provided a lock apparatus to lock the second plate 32 inserted into the slit 44.

Claims

1. A hinge comprising:

a frame-side base member which is adapted to be attached to an open frame;

a door-side base member which is adapted to be attached to a door;

a first plate to which the frame-side base member is connected;

a second plate which is hinge connected to the first plate and to which the door-side base member is connected;

a slit which is provided in the door-side base member in a width direction of the door, and into which the second plate can be inserted and removed from both a front side of the door and a back side of the door; and

a lock apparatus provided in the door-side base member to lock the second plate into the slit when the second plate is inserted in the slit;

wherein a back end of the second plate is connected to the back end of the first plate with at least one adjusting screw capable of moving upward and downward, thus enabling the door to be moved in a vertical direction for fine adjustment;

wherein a front end of the first plate is inserted into a longitudinal opening formed in the frame-side base member which is wider than a thickness of the first plate, and the front end of the first plate is connected with the frame-side base member with at least one adjusting screw capable of moving forward and backward, thus enabling the door to be moved in a horizontal direction for fine adjustment when the door is closed; and

wherein a top end of the first plate is connected to the frame-side base member with one of an adjusting screw and an adjusting cam capable of moving toward and away from the frame-side base member, thus enabling the door to be moved in a back-and-forth cross direction for fine adjustment when the door is closed.

2. The hinge according to claim 1, wherein the door-side base member is shaped to be symmetrical about a vertical center line of an end face of the door, and is adapted to be imbedded in the end face of the door without any portions of the door-side base member protruding from the door.

3. The hinge according to claim 1, wherein an opening is provided in the second plate, and the lock apparatus comprises an elastic protrusion which is adapted to be compressed when pressed by the second plate and to extend into the opening provided in the second plate when the elastic protrusion faces the opening to thereby achieve locking.

4. The hinge according to claim 3, wherein the opening in the second plate is formed at a center of a top end of the second plate, and locking of the lock apparatus is adapted to be released by compressing the elastic protrusion.
