According to the present invention, the fixing metal fitting and the connecting locking metal fitting connected via the screw are arranged so that the locking protrusion and the outer edge of the fastening metal fitting and the engagement recess of the connecting locking metal fitting and the fitting are connected together on both sides of the threaded part. In addition to this overall fitting, the locking hole of the fixing fitting and the locking protrusion of the connecting locking fitting are uneven on the other side of the screw part, that is, the opening/closing side of the hinge. Because they fit together,
In particular, the uneven fitting of the locking hole and the locking protrusion is provided on the other side of the screw portion, that is, on the opening/closing side of the hinge, so that the load when the hinge opens and closes and expands and contracts is distributed and does not concentrate on the threaded portion. This makes it possible to weaken the load applied to the communicating elongated hole part of the connection locking fitting through which the screw is inserted, and to reliably prevent breakage of this part.Moreover, the parts that fit into each of the above-mentioned irregularities are fixed. The locking slope on the metal fitting side, the two locking surfaces and the retaining surface are connected diagonally toward the opening/closing side of the hinge via the locking slope, two locking surfaces and the locking surface on the locking metal side. Because they are locked together, the load can be effectively distributed and reliably received during the opening operation of the hinge, where a particularly large load is generated, and when the connecting locking bracket is fitted to the fixing bracket. All the uneven fitting can be done by simply moving the connecting locking metal fitting diagonally towards the opening/closing side of the hinge, making installation extremely easy.In addition, the connecting locking metal fitting communicates with the screw hole of the fixing metal fitting. Because of the long communicating hole, even after the fixing bracket is fixed to the mounting member, it is easy to center it and make fine adjustments, making it easy to adjust to the mounting condition of the furniture etc. to which it is attached. Therefore, it is possible to provide a hinge fixture that is highly durable and easy to handle.
