The storage box 1 includes a box main body 2 having an opening on the front surface, and a door body 3 for opening and closing the opening of the box main body. The box body 2 is a box body that has a top plate, left and right side plates, a back plate, and a bottom plate, and is closed on five sides (top surface, left and right sides, rear surface, and bottom surface) excluding the front surface, and has an internal space. It is possible to store various electrical equipment such as a distribution board. Furthermore, a door body 3 for opening and closing the opening of the box body 2 is attached to the front surface of the box body 2. Between the box body 2 and the door body 3, hinges (upper hinge 10A, lower hinge 10B) are interposed at the upper and lower parts of their right sides, and the door body 3 is connected to the box body 2. On the other hand, it can be opened on one side using the right side as the axis.

Here, the upper hinge 10A and the lower hinge 10B, which are the main parts of the present invention, will be explained in detail.
The upper hinge 10A arranged on the upper side includes a shaft member 11 installed on the door body 3 side and a bearing member 12 installed on the box body 2 side. The shaft member 11 has a main body 21 and a shaft portion 22 that projects upward from the upper surface of the main body 21. The shaft portion 22 includes a base portion 22a having a spherical circumferential surface and a restriction portion 22b provided on the base portion 22a, and the restriction portion 22b is formed in a wall shape extending linearly in a predetermined horizontal direction. , passing through the center of the base 22a when viewed from above. The shaft member 11 is installed on the door body 3 side by fixing the main body 21 to the upper right corner of the front surface of the door body 3, and in the installed state, the shaft portion 22 protrudes vertically upward and is restricted. The portion 22b extends in a direction inclined with respect to the front surface of the door body 3 (FIGS. 3 and 5).

The bearing member 12 also connects a fixed part 23 fixed to the opening periphery of the box body 2, a bearing part 24 that pivotally supports the shaft part 22 when assembling the upper hinge 10A, and a fixed part 23 and the bearing part 24. It has a side wall part 25 and an upper wall part 26. The fixing part 23 is formed in a plate shape whose thickness is in the front-rear direction and is elongated in the vertical direction, and has a screw hole (not shown) for screwing the fixing part 23 to the box body 2. The bearing part 24 has a shaft hole 27 that can support the shaft part 22 , and the shaft hole 27 opens at the bottom surface of the bearing part 24 . Further, a first notch 28 is provided at the opening edge of the shaft hole 27 in the bearing portion 24 so that the entire base portion 22a can be exposed. Furthermore, the upper side of the first notch 28 has a width that is the same as the width of the restriction part 22b (length in the short direction when viewed from above) and a vertical length that is the same as the amount of upward protrusion of the restriction part 22b. A second notch 29 is provided extending from the first notch 28 . Therefore, the internal space of the shaft hole 27 also communicates with the outside via the first notch 28 and the second notch 29. The bearing part 24 is provided at a position a predetermined distance away from the fixed part 23 forward, with the first notch 28 and the second notch 29 facing diagonally backward to the left. Further, the side wall portion 25 is formed into a plate shape whose thickness direction is the left-right direction, and extends forward from the right end of the fixed portion 23 to connect the fixed portion 23 and the bearing portion 24. In addition, the upper wall portion 26 is formed into a plate shape whose thickness direction is the vertical direction, and extends forward from the upper end of the fixed portion 23 to connect the fixed portion 23 and the bearing portion 24. The bearing member 12 as described above is configured such that the bearing part 24 is positioned in front of the fixed part 23 and the shaft hole 28 is opened downward. By fixing it to the periphery, it will be installed on the box main body 2 side.

On the other hand, the lower hinge 10B disposed on the lower side includes a shaft member 13 installed on the door body 3 side and a bearing member 14 installed on the box body 2 side. Similar to the shaft member 11 constituting the upper hinge 10A, the shaft member 13 has a main body fixed to the front surface of the door body 3 and a shaft part protruding from the main body, but the shaft part is formed in a hemispherical shape and has a regulating part. 22b is not provided. The shaft member 13 is installed upside down with respect to the shaft member 11, that is, the shaft portion protrudes downward from the main body. Further, like the bearing member 12, the bearing member 14 has a fixing part fixed to the opening periphery of the box body 2, a bearing part for pivotally supporting the shaft member 13, etc. It is installed upside down, that is, the bearing part is located in front of the fixed part, but the shaft hole opens upward. Note that the bearing portion of the bearing member 14 does not include components corresponding to the first notch 28 and the second notch 29. The vertical distance from the opening position of the shaft hole 27 of the bearing member 12 to the opening position of the shaft hole of the bearing member 14 is approximately the vertical distance from the upper end surface of the main body 21 of the shaft member 11 to the lower end surface of the main body of the shaft member 13. considered to be the same.

In order to assemble both the upper and lower hinges 10A and 10B and to attach the door body 3 to the box body 2, the bearing members 12 and 14 were installed on the box body 2 side, and the shaft members 11 and 13 were installed on the door body 3 side, respectively. You can do the above as follows.
First, the rotational posture of the door body 3 in the opening/closing direction with respect to the front surface of the box body 2 is set to a rotational posture in which the restriction portion 22b can pass through the second notch 29 (that is, the rotational posture of the restriction portion 22b is (The rotation position is parallel to the notch 29.) Next, while maintaining the rotating position, tilt the door body 3 slightly from the vertical direction, insert the shaft portion of the shaft member 13 into the shaft hole of the bearing member 14, and rotate the shaft member 13 to the bearing member 14 to rotate the lower hinge. Assemble 10B. Then, place the shaft part 22 of the shaft member 11 adjacent to the outside of the first notch 28 and the second notch 29 in the bearing part 24 of the bearing member 12, and pull the upper part of the door body 3 toward you so that the regulating part By moving the shaft portion 22 in the extending direction of the shaft portion 22b, the regulating portion 22b and the base portion 22a can be moved into the shaft hole 27 through the second notch 29 and the first notch 28, respectively. For example (FIG. 7), the shaft member 11 is pivotally supported by the bearing member 12, and the upper hinge 10A is also assembled, and the assembly of both the upper and lower hinges 10A, 10B and the attachment of the door body 3 to the box body 2 are completed.

Furthermore, after the door body 3 is attached to the box body 2, if the door body 3 in the rotational position is rotated in the closing direction to take the closing position in which the opening of the box body 2 is closed, the phase of the regulating portion 22b and The phase with the second notch 29 will be shifted (FIG. 5, the regulating part 22b is not in the above rotational position), and in this state, the door body 3 may be removed from the box body 2, or the door body 3 may be removed from the box body 2. It becomes impossible for the box body 2 to accidentally fall off. Also, when the door body 3 is rotated in the opening direction and placed in the open position rotated 90 degrees with respect to the front surface of the box body 2, the phase of the regulating portion 22b and the phase of the second notch 29 are do not match (FIG. 6, the restricting portion 22b does not take the above-mentioned rotational posture during rotation in the opening/closing operation). Therefore, the door body 3 will not accidentally fall off from the box body 2 during the opening/closing operation between the closed position and the open position. Furthermore, when the door body 3 is further rotated in the opening direction beyond the above-mentioned open position, and the rotation angle with respect to the front surface of the box main body 2 is set to the attachment/detachment position at a predetermined attachment/detachment angle, the phase of the regulating portion 22b and the second cut Since the phase with the notch 29 matches (FIG. 7, the regulating part 22b assumes the above rotational position), the shaft part 22 can be removed from the shaft hole 28 (disassembly of the upper hinge 10A), and the box body of the door body 3 can be removed. 2 can be removed.

According to the upper hinge 10A of the door body 3 in the storage box 1 having the above-described configuration, the shaft portion 22 of the shaft member 11 has a wall-shaped regulating portion 22b extending in a predetermined horizontal direction through the center of rotation of the shaft member 11. On the other hand, the shaft hole 27 of the shaft portion 22 is provided in the bearing portion 24 of the bearing member 12 by moving the shaft portion 22 in the direction in which the restriction portion 22b extends only when the restriction portion 22b is in a predetermined rotational posture. A first notch 28 and a second notch 29 are provided to allow movement inside and outside the body. Therefore, by adjusting the rotational posture of the regulating part 22b and the positional relationship between the shaft part 22 and both notches 28 and 29, and moving the upper part of the door body 3 in the direction in which the regulating part 22b extends, the upper hinge 10A can be adjusted. It is possible to assemble/disassemble, and also to attach and detach the door body 3 to the box body 2.

Moreover, when the door body 3 is in the closing position to close the opening of the box body 2, the regulating part 22b is not in the rotating position, and the movement of the shaft part 22 to the outside of the shaft hole 27 is restricted. Further, when the door body 3 is opened/closed between the closed position and the open position erected at 90 degrees with respect to the front surface of the box body 2, the regulating part 22b does not take a rotating position during rotation, and the shaft part 22 Movement outside the shaft hole 27 is kept restricted. Further, when the door body 3 is opened beyond the open position and is set to a mounting/dismounting position in which the angle with respect to the front surface of the box body 2 is a predetermined mounting/dismounting angle, the regulating portion 22b is placed in a rotational position and the shaft hole 27 of the shaft portion 22 is moved out. It is now possible to move to. Therefore, even though the door body 3 is attached with the simple configuration described above, there is no leakage from the box body 2 of the door body 3 not only when the opening of the box body 2 is closed, but also during the opening/closing operation. It is possible to prevent the inadvertent falling off, and it is possible to improve usability.

In addition, the structure related to the hinge structure of the door body in the storage box of the present invention is not limited to the aspect described in the above embodiment, and the structure related to the box body, the door body, and the hinge of the present invention Changes may be made as necessary without departing from the spirit.

For example, in the above embodiment, only the upper hinge is provided with a regulating portion on the shaft portion and a notch on the bearing portion, but there is no problem if a similar structure is adopted for the lower hinge. If at least one of the upper and lower hinges is provided with a regulating portion in the shaft portion and a notch in the bearing portion, the door body can be easily attached and detached from the box body.
Further, the extending direction of the restricting part in the shaft part, the position and shape of the notch in the bearing part, etc. can be changed as appropriate. That is, there is no problem even if a notch is provided in the front of the bearing part or the regulating part is extended in the front-rear direction. Furthermore, the degree to which the door body must be rotated in the opening direction with respect to the box body to enable attachment and detachment can be changed as appropriate as long as the angle is greater than 90 degrees.

Furthermore, as the hinge structure of the door body, a different type of hinge (for example, a first pin receiving member is fixed to the box body, a second pin receiving member is fixed to the door body, and both Of course, it is also possible to provide a conventionally known hinge in which a pin member is inserted so as to pass through the pin receiving member.
In addition, in the above embodiment, the door body is provided to open to the right, but needless to say, the present invention can be suitably employed as a hinge structure for a door body that opens to the left.
