The cabinet 1 includes a main body 2 and a door 3 that can be opened and closed. A hinge 4 is disposed between an upper front plate 2 a of the main body 2 and a door frame 3 a at the upper end of the door 3. 3 can be opened and closed.
The hinge 4 is shown in an enlarged perspective view in FIG. 4 in an opened state of the arm, in FIG. 5, a perspective view in a state in which the arm is closed, and in FIG. 6, a plan view, and FIG. A cross-sectional view taken along the line -A, a side view in FIG. 8, and a plan view in FIG. 9 with the arm fully open are shown.

The hinge 4 includes a main body 5, an arm 6 that rotates with respect to the main body 5, and a rivet 9 and a washer 8 that connect the main body 5 and the arm 6.
The main body 5 includes a fixed portion 5a fixed in contact with the upper front plate 2a of the cabinet, a horizontal portion 5b bent substantially horizontally from the upper end of the fixed portion 5a to the near side, and the right end of the horizontal portion 5b shown in the figure. The engagement portion 5c is formed in a semicircular shape in plan view and further extends horizontally toward the front side. The horizontal portion 5b on the right end side of the engagement portion 5c is notched in an inclined shape and has a stopper. A portion 5d is formed.

  On the other hand, the arm 6 is continuous on a fixed portion 6a fixed to the upper end surface of the door frame 3a, a first horizontal portion 6b extending from the fixed portion 6a in the same plane, and the right end of the first horizontal portion 6b in the figure. The vertical portion 6c rising upward and the second horizontal portion 6d bent substantially horizontally in parallel with the first horizontal portion 6b at the upper end of the vertical portion 6c. The first horizontal portion 6b, the vertical portion 6c, An engagement portion K having a U-shaped cross section is formed in the second horizontal portion 6d, and the engaged portion 5c of the main body is moved up and down with a flat washer 8 in the U-shaped engagement portion K. It is comprised so that it can insert and interpose.

The first horizontal portion 6b of the arm is formed with a first through hole 7a having a dish-like recess on the lower surface, and the first horizontal through hole 7a is formed in the second horizontal portion 6d. The second through hole 7b having a smaller diameter is formed so as to penetrate vertically.
In this example, the second through hole 7b is a quadrangular through hole.
Further, a through hole 7c that matches the first through hole 7a and the second through hole 7b is formed in the engaged portion 5c of the main body, and the through hole 7c on the main body side is the first through hole 7a. And the same diameter.

Also, three countersunk holes 7d, 7d, 7d for inserting fixing screws are formed through the fixing part 5a of the main body, and two countersink holes 7e are formed in the fixing part 6a of one arm 6. 7e are vertically penetrated, and the upper surface of the countersunk holes 7e, 7e is formed in a dish shape.
The rivet 9 can be inserted from below the first through hole 7a with the engaged portion 5c of the main body fitted into the engaging portion K of the arm 6 with the washer 8 interposed therebetween. As shown in the plan view of FIG. 11 and FIG. 7, it is made of stainless steel similar to the other members, and is large on the lower end side of the shaft portion 9a having substantially the same diameter as the through hole 7c and the first through hole 7a. A dish-shaped head portion 9b having a diameter is formed, and a quadrangular columnar convex portion 9c is formed in a protruding shape on the upper end side.

  Since the first through-hole 7a is formed in a dish shape with its lower end expanded in the downward direction, the head 9b of the rivet 9 is swallowed into the first through-hole 7a, and the lower end of the first through-hole 7a The lower end of the head 9b is flush and the rivet 9 is fitted into the through holes 7a, 7b, 7c, and the convex portion 9c of the rivet 9 is caulked from above outside the second through hole 7b of the arm, The convex portion 9c is fixed in the second through hole 7b. In this state, the rivet 9 is fixed, and the arm 6 can rotate in a horizontal plane with respect to the main body 5 about the shaft portion 9a of the rivet 9. As shown in FIG. 9, when the arm 6 is fully opened, the rear end surface of the engaging portion K comes into contact with the stopper portion 5d, thereby suppressing the rotation at an angle larger than this and causing damage. It is configured to be prevented.

In this way, the main body 5 and the arm 6 are rotatably connected via the rivet 9, and in this state, the arm fixing portion 6a is fixed to the upper end surface of the door frame 3a with the screw 10 as shown in FIG. Then, the head portion 9b of the rivet 9 is hidden by the upper end surface of the door frame 3a. In this state, the arm fixing portion 6a and the first horizontal portion 6b come into contact with the upper surface of the door frame 3a.
Therefore, by fixing to the door frame 3a in this way, even if the rivet 9 is worn, the rivet 9 does not come out downward, so that the door 3 does not fall off. Therefore, a cabinet in which the door does not come off even when the door is repeatedly opened and closed can be configured.

  In this example, since the convex portion 9c of the rivet 9 and the second through hole 7b of the arm are formed in a quadrangular shape, the convex portion 9c of the rivet is prevented from rotating in the fitted state in the second through hole 7b. Even when 6 is rotated, the rivet 9 does not rotate synchronously, wear of the convex portion 9c of the rivet 9 is suppressed, and the durability of the hinge 4 is improved.
