DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an example of a box door adjustment structure according to the present invention, and shows a partial perspective view of a box body with a door opened. In FIG. 1, reference numeral 1 denotes a box main body that is attached to a wall surface and stores equipment, 2 is a door plate that closes the opened front surface of the box main body 1, and 3 is a door plate 2 that is rotatably connected to the box main body. Hinge members 4 are spacer members for adjusting the inclination of the door plate 2.
The box main body 1 and the door plate 2 are connected by two hinge members 3 of an upper hinge member 3 shown in FIG. 1 and a lower hinge member 3 (not shown). 2 is rotated to freely close / open.

The hinge member 3 has a box main body side hinge piece 31, a door plate side hinge piece 32, and a pin 33 that connects the two and serves as a rotation shaft. FIG. 2 is a cross-sectional explanatory view of the box hinge portion cut at the center of the hinge member 3 and shows a state in which the door plate 2 is closed.
As shown in FIG. 2, the hinge mounting portion 11 of the box body 1 is arranged in parallel to the side surface 1 a of the box body 1, and the box body side hinge piece 31 is mounted on the back surface that is the side surface 1 a side of the hinge mounting portion 11. It is done.

The box main body side hinge piece 31 has a flat mounting surface 31a that is in close contact with the hinge mounting portion 11 of the box main body 1 and a cylindrical body 31b through which the pin 33 is inserted, and the cylindrical body 31b is formed at two locations on the upper and lower sides. . Screw holes 31c into which the screws 5 are screwed are formed at two places on the upper and lower sides of the mounting surface 31a. In addition, the corresponding hinge attachment portion 11 is provided with a hole 11a through which the screw 5 is inserted.
The mounting surface 31a is disposed on the back surface of the hinge mounting portion 11, and the box main body side hinge piece 31 is screwed into the mounting surface 31a via the hinge mounting portion 11 from the inside of the box main body 1. In close contact.

  The door plate-side hinge piece 32 is a cylinder through which the pin 33 is inserted, and a cylinder disposed between the pair of cylinders 31 b of the box body-side hinge piece 31 is welded to the door plate 2. Yes.

The spacer member 4 is a rectangular plate body, and as shown in FIG. 1, notches 41 (first notches) are formed at two locations in accordance with the position of the screw 5, that is, in accordance with the screw hole 31c formed in the mounting surface 31a. A notch 41a and a second notch 41b) are provided. However, the shape of both notches 41 is different, and the first notch 41a is a hook formed by cutting the inside of the notch extending toward the outside in the longitudinal direction of the spacer member 4 and forming an L shape as a whole. The second notch 41b is a simple U-shaped notch.
The spacer member 4 may be made of a metal plate. However, the spacer member 4 may be made of a synthetic resin because it is in surface contact with the hinge member 3.

  The spacer member 4 thus formed is attached as follows. In the box body in which the door plate 2 is attached to the box body 1, two screws 5 are loosened to form a gap between the attachment surface 31 a of the box body side hinge piece 31 and the hinge attachment portion 11 of the box body 1. . Then, the spacer member 4 is moved and inserted from the back of the box body 1 in parallel to the front as shown by the arrow M1 in FIG. 1 (arrow M2 in FIG. 2).

At this time, the spacer member 4 is arranged and inserted so that the first notch 41a is on the upper side. As a result, the inserted screw 5 is caught by the hook action of the first notch 41a formed in an L shape, and the spacer member 4 does not easily fall off while maintaining the hanging state.
After the insertion, if the loosened screw 5 is tightened, the mounting of the spacer member 4 is completed. However, if only one spacer member is inserted and the inclination (one down) of the door plate 2 is not sufficiently corrected, additional insertion is performed.

Thus, if the spacer member 4 is clamped by the hinge mounting portion 11 on the box body side of one of the hinge members 3 provided at the upper and lower two locations, the inclination of the door plate 2 can be adjusted, that is, Downward adjustment is possible. In addition, since the spacer member 4 disposed between them is provided with a notch 41 in accordance with the position of the screw 5, it is possible to remove the screw 5 between the hinge mounting portion 11 and the box body side hinge piece 31. It can be inserted and arranged, and the inclination of the door plate 2 can be adjusted with a simple operation. Further, even if the screws 5 used on the box body 1 side are loosened, the door plate 2 can be maintained in a stable state without changing its inclination unless the spacer member 4 falls off.
Further, since the notch 41 of the spacer member 4 is formed in a hook shape at one place formed at the end, it is disposed at a predetermined position between the hinge mounting portion 11 and the box body side hinge piece 31. In order to maintain the state hung on the screw 5 like a hanger, it is difficult to come off. Therefore, the spacer member 4 inserted into the gap is hard to come off and can be attached by a simple operation.

In the above embodiment, only the first cutout 41a of the two cutouts 41 formed in the spacer member 4 has a hook shape. However, as shown in FIG. You may form in a hook shape similarly to the notch 41a. In this case, however, they are formed in the same direction. Further, as another shape of the hook-shaped notch 41, as shown in FIG. 3B, the hook-shaped notch 41 may be formed by being linearly cut in an oblique direction (third notch 41c) without being bent.
The spacer member 4 is provided with notches 41 at two locations, but the spacer member 4 is changed according to the number of screws to be screwed. In that case, the hook-shaped notch 41 may be formed at one location on one end, but if it is formed in an L shape or inclined in the same direction, all the notches may be formed in a hook shape. It is hard to come off as well.
Further, in a normal state in which no distortion such as one-sided down occurs, the spacer members 4 can be stored and prevented from being lost by holding the same number of spacer members 4 between the upper and lower hinge members 3. And it can respond promptly when a one-sided fall etc. occur. Also, it is convenient to prepare spacer members 4 having different thicknesses.
