2. Description of the Related Art Generally known main hinges include a hidden hinge (see Japanese Utility Model Publication No. 25-7318).
There are a slide hinge (see Japanese Patent Publication No. 47-12968), a biaxial hinge (see Japanese Utility Model Publication No. 35-890), an offset hinge, and the like. However, the hidden hinge is mounted between the vertical frame of the door and the vertical frame of the door frame, and when the door is opened, the hinge protrudes greatly into the inner surface of the opening to obstruct the entry and exit of the stored luggage, and the slide hinge is Generally, it is not possible to expect a large opening angle within 90 degrees. A biaxial hinge is one in which the door breaks when opening and closing and cannot be opened and closed smoothly. An offset hinge not only impairs the appearance of the hinge by protruding to the outer surface, but is also undesirable in crime prevention. In addition, these hinges are all attached to relatively light doors, and are not less than 2.5 m, such as heavy doors, especially building equipment, computer room inspection doors or warehouse doors. Some large doors could not withstand the strength and could be damaged or collapsed. Therefore, a hinge (see Japanese Patent Application Laid-Open No. 4-333787) in which this is improved has been developed.
