In the figure, reference numeral 1 denotes a hinge for receiving an upper end of an opening / closing door 2, which is a hinge main body 3 having a cross-sectional shape, and a support shaft projecting upward on an outer surface near one end in a longitudinal direction of a horizontal upper plate portion 4 of the main body 3. A horizontal shaft 8 is provided inside the side plate portion 6 in the vicinity of one end in the length direction of the portion 5 and one side plate portion 6 of both side plate portions 6 and 7 into which the upper end corner portion of the opening / closing door 2 is fitted from below. It comprises an opening / closing door 2 which is pivotally supported and fitted between the both side plate portions 6 and 7, and a press-fitting plate 9 which can be inserted into and pulled out from between one side plate portion 6. One end of the press-fitting plate 9 is pivotally supported at one end to form a flattened surface 10 which is thinner than the other portion, and a surface 11 facing one side plate portion 6 at other portions except the vicinity of the pivotal support portion.
Protrudes from the flat surface 10. The press-fitting plate 9 is tapered between the flat surface 10 and the other surface 11 so that the press-fitting plate 9 can be easily pressed into the inside of the one side plate portion 6, and the surface 11 is formed in an upper narrowed shape. Has been formed. Further, a bent piece 12 that faces outward is provided at the lower end of the other end of the press-fitting plate 9 in the longitudinal direction. Reference numeral 13 denotes notches formed at the lower end portions of the one side plate portion 6 at both ends in the length direction. By the way, when the press-fitting plate 9 protrudes at a right angle to the one side plate portion 6, the surface 11 does not come into contact with the one side plate portion 6.

Next, reference numeral 14 is a hinge for receiving the lower end of the opening / closing door 2. The hinge 14 has a symmetrical shape with the hinge 1 for receiving the upper end of the opening / closing door 2, and the hinge main body 15 has a sectional shape and its horizontal bottom plate portion 16 is provided. Near one end in the length direction of one side plate portion 18 of both side plate portions 18 and 19 in which a supporting shaft portion 17 is projected downward on the outer surface near one end in the length direction and the lower end corner portion of the opening / closing door 2 is fitted from above. Like the hinge 1, the press-fitting plate 20 has a horizontal axis.
It is pivoted by 21. One end of the press-fitting plate 20 has one end pivotally supported as a flat surface 22 thinner than the other portion, and the surface 23 facing one side plate portion 18 in the other portion excluding the vicinity of the pivotal support portion is more than the flat surface 22. Is also protruding. The press-fitting plate 20 is tapered between the flat surface 22 and the other surface 23 so that the press-fitting plate 20 can be easily press-fitted inside the one side plate portion 18, and the surface 23 is formed in a downward constricted shape. Has been done. 24 is a bent piece formed outward at the upper end of the other end of the press-fitting plate 20 in the lengthwise direction, and 25 is a notch formed in the lower end of both ends in the lengthwise direction of the one side plate portion 18. . By the way, when the press-fitting plate 20 protrudes at a right angle to the one side plate portion 18, the surface 23 does not come into contact with the one side plate portion 18.

When the opening / closing door 2 is supported by the above two hinges 1 and 14, the upper and lower corner portions of the opening and closing door 2 are fitted between the side plate portions 6 and 7 of both hinges 1 and 14 and between 18 and 19. Then, the press-fitting plates 9 and 20 are press-fitted by pressing the bending pieces 12 and 24 between the opening / closing door 2 and the side plate portions 6 and 18 on one side. At this time, the surfaces 11 and 23 of the press-fitting plates 9 and 20 are in the shape of concavities as described above, and the surfaces 11 and 23 and the planes 10 and 22 are tapered. Thus, the press-fitting plates 9 and 20 can be smoothly press-fitted. This press-fitting plate 9,20
By press-fitting, the surfaces 11 and 23 of the press-fitting plates 9 and 20 are pressed against the inner surface of the one side plate portion 6 and 18, and the opening / closing door 2 is sandwiched between the press-fitting plate 9 and 20 and the other side plate portion 7 and 19. Then, the opening / closing door 2 and the hinges 1 and 14 are connected. The hinges 1 and 14 connected to the opening / closing door 2 support the opening / closing door 2 rotatably around the vertical axis by fitting the support shafts 5 and 17 into the upper and lower holes 27 and 28 of the cabinet 26, for example. It will be.

In the above structure, the opening / closing door 2 is pivotally supported on the cabinet 26 by the upper and lower hinges 1 and 14, but when the hinges 1 and 14 are set on the opening / closing door 2, If there is an error in the thickness, the press-fitting plates 9 and 20 are difficult to enter into the hinge bodies 3 and 15, and there is play between the press-fitting plates 9 and 20 and the opening / closing door 2 to cause hinges 1 and 14 and the opening / closing door. There was a problem that the two could not be joined firmly. Also, although the upper and lower hinges 1 and 14 are symmetrical to each other, it is impossible to use the same ones. Therefore, the upper and lower hinges 1 and 14 must be prepared by reversing the attachment of the press-fitting plate to the hinge body. No, it was troublesome. This is also the case when the opening direction of the opening and closing door is different, and it was necessary to prepare the right opening and the left opening in which the press-fitting plate was attached to the hinge body in reverse.

The present invention solves such a problem. Even if an error occurs in the thickness of the opening / closing door, the opening / closing door can be firmly supported and the opening / closing door can be supported only by preparing one kind of hinge. The purpose is to do so.

Means for Solving the Problems In order to solve this problem, the present invention is directed to a hinge main body having a cross section into which an opening / closing door is fitted, and a horizontal plate portion of the hinge main body in the vertical direction outward from the vicinity of one end in the longitudinal direction. And a press-fitting plate that is removably disposed along the inner side of the two side plate portions of the hinge body and that sandwiches the open / close door between either side plate portion. This press-fitting plate has two plate-like members which are rotatably connected to each other with pins and overlapped with each other, and at least one plate portion of the two plate-like members has two plate-like members. A protrusion is provided between the two plate-shaped members to expand the overlapping portion of the two plate-shaped members when the plate-shaped members are in a straight state of 180 degrees.

With this configuration, even if a large error occurs in the thickness of the opening / closing door, the height of the protrusion of the plate-like member of the press-fitting plate is increased to ensure the connection between the opening / closing door and the hinge body. be able to. The opening / closing door can be supported by replacing the press-fitting plate with respect to the hinge body depending on the vertical and horizontal positions of the opening / closing door simply by preparing one kind of pivot hinge.
