Hinge
An object is to provide a hinge capable of preventing an unintentional shift in height to an up-and-down direction with respect to rotation of a door. A hinge comprises a holder part supporting rotatably a door and for holding the door, a supporting part and for rotatably supporting the holder part from below, a rotation part having a screw on an inner circumference for rotatably connecting to the screw thread of the rotation part, a first regulation part disposed to the holder part and for regulating rotation of the rotation shaft with respect to the supporting part, and a second regulating part disposed to the holder part and for regulating up-and-down movement of the adjustment ring with respect to the holding part along an upper-and-lower direction.
1. A hinge for supporting rotatably a door comprising:
a holder part for holding a door;
a supporting part having a screw on an outer circumference and for supporting rotatably the holder part from below;
a rotation part having a screw on an inner circumference and for rotatably connecting to the screw of the supporting part and for rotating with respect to the holder part;
a first limitation part disposed to the holder part and for limiting rotation of the supporting part with respect to the holder part; and
a second limitation part disposed to the holder part and for limiting movement of the rotation part in an up-and-down direction with respect to the holder part.
2. The hinge of claim 1 , wherein the first limitation part comprises a part including a through hole for inserting the supporting part and having a non-circular shape; and
the part including the through hole contacts with an outer face of the supporting part.
3. The hinge of claim 2 , wherein the second limitation part comprises a receptacle part for inserting the rotation part; and
the receptacle part contacts with an upper end of the rotation part.
4. The hinge of claim 1 , wherein the second limitation part comprises a receptacle part for inserting the rotation part; and
the receptacle part contacts with an upper end of the rotation part.
5. The hinge of claim 1 , wherein the hinge further comprises an adjustment member for making the holder part move along a lateral width direction of the door while not making the supporting part move; and
the adjustment member fixed to the holder part extends along the lateral width direction of the door and is not inserted to the supporting part standing up along an up-and-down direction.
6. The hinge of claim 1 , wherein the hinge comprises a hole for exposing the rotation part outside.
