[0020]

The hinge of the present invention can be embodied and used as described above. According to the hinge of the present invention, the hinge passes through the axis of the support shaft connecting both blade plates. When the hinges are attached, since the projections that match the central imaginary plane perpendicular to the plane when the two blades are developed on one plane are provided so as to protrude from the mounting surface of the blades, When the two members (the side wall and the door, etc. of the furniture main body) connected by the hinge are developed on one plane, the concave groove formed by the chamfered corner of each member between the contact end surfaces between the two members. The hinge (the support shaft) can be accurately positioned at a predetermined mounting position only by fitting the projection.

That is, since the hinge (the support shaft) can be positioned with a tactile sensation, the hinge at the time of mounting is more compared with the conventional case where the hinge (the support shaft) must be positioned only visually. The positioning of the hinge can be performed easily and accurately, and even a layman can easily utilize this kind of hinge.

According to the configuration of the second aspect, when the two members (the side wall and the door of the furniture body) connected by the hinge are developed on one plane, the contact end face between the two members. The protrusions can be easily and reliably fitted into the minute streak-like concave grooves formed by the chamfered corners of the respective members, and the hinges can be reliably regulated in a certain direction.

According to the third aspect of the present invention, even when the blade plate is formed of a metal plate, the positioning projection is formed when the cam of the click mechanism manufactured separately from the blade plate is manufactured. The projection can be arranged at a predetermined position of the hinge by incorporating the cam,
This facilitates implementation for hinges in which the blades are made of metal plates. Further, when the cam is made of a synthetic resin, even if it is a metal projection, particularly a metal projection having a pointed tip as described in claim 2, the worker handling the hinge can use the tip of the projection. The risk of injuries to fingers and the like is eliminated, and the risk of inconvenience, such as the collision of the projection with another object when the hinge is handled and the tip of the projection being lost, is reduced.

Further, according to the configuration of the fourth aspect, particularly in the case of a hinge made of a die-cast blade, it is possible to eliminate wear and squeak noise caused by friction between bearings supporting the support shaft. Since the protrusion is formed on the washer made of synthetic resin, the same effect as in the case of the configuration according to claim 3 can be expected, and the protrusion is arranged at two places spaced apart in the longitudinal direction of the support shaft. It can also improve the hinge positioning effect.
