For the front door 2 and the side door 3, hinges attached to the left side of the front door 2 and the rear side of the side door 3 are coupled to the hinge bodies 6 and 6 and the hinge bodies 7 and 7 by hinge pins, respectively. The box body 1 is held openably and closably. Both the front door 2 and the side door 3 are formed in a shallow box shape by bending the periphery, and a handle 10 is attached to the right side portion of the front door 2. Further, a folded portion 11 that is folded back and extended in a crank shape is formed at a bent portion of the front end portion of the side door 3, and an engagement hole 12 is provided in the folded portion 11. The handle 10 preferably incorporates a locking device. A clasp 13 that is rotated by operating the handle 10 is attached to the front door 2, and the clasp 13 has engaging portions at both ends. 14 and 15 are provided.
[0009]
In this configuration, the handle 10 is operated so that the engaging portions 15 and 14 of the clasp 13 are positioned up and down as shown by the one-dot chain line in FIG. 4, and the side door 3 and the front door 2 are sequentially closed. When the upper handle 10 is operated, the engaging portions 14 and 15 are engaged with the engaging holes 9 and 12, respectively. By engaging the engaging portion 14 and the engaging hole 9, the front door 2 is fixed to the right wall surface 8 of the front frame portion 4, and the engaging portion 15 and the engaging hole 12 are engaged. By doing so, the side door 3 is fixed to the front door 2. As a result, the front door 2 and the side door 3 can be opened and fixed simultaneously only by operating the handle 10.
[0010]
5 and 6 show a first reference example of the present invention, in which the front door 2 and the side door 3 are held openably and closably with respect to the electric / electronic device storage box main body 1. 2 and the side door 3 are formed in a shallow box shape, the handle 10 is attached to the right side of the front door 2, the clasp 13 linked to the handle 10 is attached, and the side door 3 is folded back. Forming the part 11 is the same as that of the first embodiment. In this first reference example , the engagement hole 12 is not provided in the folded portion 11 of the side door 3, and the bent portion 16 is formed by further bending the bent portion at the right end portion of the front door 2. The clasp 13 is provided with an engaging portion 14 on one side.
[0011]
In this configuration, the handle 10 is operated so that the engaging portion 14 of the clasp 13 is positioned below as shown by a one-dot chain line in FIG. 5, and the side door 3 and the front door 2 are sequentially closed and the handle is closed. 10 is operated, the engaging portion 14 engages with the engaging hole 9, and the engaging portion 14 and the engaging hole 9 engage with each other so that the front door 2 is in the right side wall surface 8 of the front frame portion 4. It will be fixed to. At this time, the front door 2 covers the folded portion 11 of the side door 3 and the opening of the side door 3 is suppressed, but the tip of the folded portion 16 of the front door 2 abuts the folded portion 11. Thus, the side door 3 is fixed with little play. As a result, the front door 2 and the side door 3 can be opened and fixed simultaneously only by operating the handle 10. Here, the side door 3 is prevented from being opened when the front door 2 is covered. If the dimensions of the front door 2 and the side door 3 are appropriately selected, the side door 3 can be formed without the bent portion 16. Can be fixed without play. However, it is preferable to provide the bent portion 16 from the viewpoint of preventing foreign matter from entering the box.
[0012]
FIG. 7 shows a second reference example of the present invention, which is obtained by adding a hook metal fitting 17 for fixing the side door 3 to the electric / electronic device storage box body 1 with respect to the first reference example. It is. The hook 17 is freely engageable with an engagement hole 18 provided in the folded portion 11 of the side door 3, and is pivotally attached to the front surface of the electric / electronic device housing box body 1. Reference numeral 19 denotes a notch provided in the bent portion 16 in order to prevent the bent portion 16 of the front door from interfering with the hook metal fitting 17.
[0013]
In the second reference example , the front door 2 and the side door 3 are opened and fixed simultaneously by only operating the handle 10, as in the first reference example. By closing and engaging the hook metal fitting 17 with the engagement hole 18, it is possible to prevent the side door 3 from being naturally opened when the front door 2 is opened. That is, whether or not the side door 3 is naturally opened when the front door 2 is opened for convenience can be selected depending on whether or not the hook 17 is engaged with the engagement hole 18. . Further, since the hook 17 is covered by the front door 2 when the front door 2 is closed, the selection state is not changed when the front door 2 is closed.
[0014]
The hook metal fitting 17 that suppresses the natural opening of the side door can be attached to the first embodiment, and the hook metal fitting 17 can be replaced with a magnet. If the side door is opened unintentionally, it may cause a problem that it collides with the one placed on the side, and the hook 17 is used to avoid it. The operation is cumbersome and can be forgotten. When a magnet is used, there is an advantage that the natural opening of the side door 3 when the front door 1 is opened is surely suppressed, it can be easily pulled off, and the attachment is easy.
[0015]
In the above-described embodiment and reference example , the side surface is a door, but the side surface is a side plate, the rear side of the side plate is hooked on the box body for electrical and electronic equipment storage, and the clasp provided on the front door is the front side of the side plate. It can be fixed together, or it can be prevented from opening the side plate by covering the front door. Furthermore, the side plate can be used as a side plate, and the front side and the rear side of the side plate hooked on the side surface can be engaged with the clasps provided on the front door and the rear door, respectively. Alternatively, the opening of the side plate can be suppressed by covering the front door and the rear door.
