FIG. 1 shows a first embodiment of the present invention.
A description will be given based on FIGS. Members having the same basic functions as those of the conventional example are denoted by the same reference numerals.

As shown in FIG. 2, the electric device storage box has a box body 3 having an opening on one side for storing electric devices such as a breaker 1 and a watt-hour meter 2, and a portion of the breaker 1 protruding. Inner lid that closes the opening on the breaker 1 side of the box 10 in the state
4 and watt-hour meter 2 with part of watt-hour meter 2 protruding.
A lid 5 that closes the opening on the side, an outer lid 6 that closes the inner lid 4 and the lid 5, and a lid that is provided in the box 3 and has a lid attached to one end and a box Lid attachment device attached to 3 7
It is composed of

As shown in FIGS. 1 and 3, the box 3 has a bottom plate 9 to which a substantially convex fixing member 8 is welded,
A side plate 10 standing upright from the four circumferences is formed in a shape having an opening on one surface, and a wooden board 11 is attached to a fixing member 8 at a predetermined distance from the bottom plate 9. The wooden board 11 has a fixing member
A through hole 12 through which the eight screws pass is formed, and is attached to the fixing member 8 by screwing the nut 13 to the screw.

The inner lid 4 has a breaker 1 on the right side in FIG.
2 is rotatably supported by an inner lid support (not shown) attached to a frame (not shown) for fixing, and the left side in FIG. 2 is screwed to the inner lid support.

As shown in FIGS. 1 to 3, the lid 5 closes the opening of the box 3 on the side of the watt-hour meter 2.
It is attached to the box 3 by the lid attaching device 7 attached to the box. As shown in FIG. 4, the lid attaching device 7 has a substantially U-shaped metal fitting 14 attached to the four corners of the wooden board 11 and a lid attaching screw hole 15a for supporting the lid 5 at one end. And the other end side is approximately U-shaped
And a rod-shaped lid support metal fitting 15 attached to the base 14.

The substantially U-shaped bracket 14 includes a first opposing piece 16 and a second opposing piece 17 that face each other in the front and back directions of the wooden board 11.
It is formed in a substantially U-shape from the opposing piece 16 and the connecting piece 18 that connects the second opposing piece 17, and is attached to the four corners of the wooden board 11. First
The opposing piece 16 is formed with a screw hole 19 for attaching the rod-shaped lid support metal fitting 15. The rod-shaped lid support member 15 has a screw portion 20 that is screwed into the screw hole 19 of the substantially U-shaped metal member 14, and when the screw portion 20 is screwed into the screw hole 19 and tightened, the wooden board 11 is in the second position. Wood board contact portion 21 sandwiched between opposing pieces 17
The screw portion 20 is screwed into the screw hole 19 so that the screw portion 20 is attached to the substantially U-shaped bracket 14.

Further, the screw portion 20 of the rod-shaped cover support member 15 is screwed into the screw hole 19 at the second facing piece 17 of the substantially U-shaped metal member 14 and the wood plate contact portion 20 of the rod-shaped cover support member 15. The projections 22 and 23 that bite into the wooden board 11 when tightened are formed, so that the wooden board 11 can be firmly held.

Next, a method of attaching the lid attaching device 7 to the wooden board 11 will be described with reference to FIG. That is, first the wooden board 11
Is disposed between the first opposing piece 16 and the second opposing piece 17 of the substantially U-shaped bracket 14. Next, the screw portion 20 of the rod-shaped lid support metal fitting 15 is screwed into the screw hole 19 of the substantially U-shaped metal fitting 14 so that the rod-shaped lid support metal fitting 15 is formed.
By hand, the wooden board 11 can be sandwiched between the second opposing piece 17 and the wooden board contact portion 21. That is, the lid attaching device 7 can be attached to the wooden board 11.

According to the present embodiment, a lid attaching device comprising a substantially U-shaped metal fitting and a rod-shaped lid supporting metal fitting is used for the lid covering the watt-hour meter, but a wooden board is used as the breaker. Needless to say, the same lid attaching device can be used for the inner lid if it is attached to the inside of the box.

Next, a second embodiment of the present invention will be described with reference to FIGS.
It will be described based on. The difference from the first embodiment is that
This is because a retaining portion 24 is provided between the screw portion 20 and the wooden plate contact portion 21 of the rod-shaped lid support metal fitting 15, and only this point will be described.

That is, the screw portion 20 of the rod-shaped lid support member 15
A retaining portion 24 having a spring property larger than the diameter of the substantially U-shaped metal fitting 14 is provided between the wooden board abutting portion 21 and the screw hole 19 when attaching to the substantially U-shaped metal fitting 14. The contact portion 21 is inserted, and the retaining portion 24 is turned against the spring force.
And the retaining portion 24 is returned to the original state by its spring force, whereby the retaining is stopped.

According to each of the above-described embodiments, the substantially U-shaped metal fittings are attached to the four corners of the wooden board. However, if the substantially U-shaped metal fitting is formed as shown in FIG. Can be attached to the location. Further, according to each embodiment, the projection is provided on both the second facing piece of the substantially U-shaped metal fitting and the rod-shaped lid support metal fitting, but it goes without saying that either one may be provided.

[0022]

According to the electric equipment storage box according to the first aspect, the lid attaching device has a substantially U-shaped metal fitting and a rod-shaped lid supporting metal.
And the substantially U-shaped metal fitting includes a screw.
A first facing piece having a hole formed therein and facing the front side of the wooden board;
And a second opposing piece opposing the back side of the plate.
And the rod-shaped lid support metal fitting is screwed into the screw hole.
And screwing the screw part into the screw hole and tightening
Wood that sandwiches the wooden board between the second facing piece when
And a plate contact portion, so that a rod-shaped lid is inserted into the screw hole of the substantially U-shaped metal fitting with the substantially U-shaped metal fitting disposed between the first and second opposed pieces. When the screw portion of the support bracket is screwed and the rod-shaped lid support bracket is manually tightened, the wooden board is sandwiched between the wooden board contact portion and the second facing piece, and the substantially U-shaped bracket and the rod-shaped lid support bracket are attached to the wooden board. No special jig is required, and the attachment work is easy.

According to the second aspect of the present invention, at least one of the second facing piece of the substantially U-shaped metal fitting and the wooden plate contact portion of the rod-shaped lid supporting metal fitting is provided with the screw part of the rod-shaped lid supporting metal fitting. Is provided with a protrusion which is screwed into the screw hole of the substantially U-shaped metal fitting when tightened, so that the substantially U-shaped metal fitting and the rod-shaped lid support metal fitting are firmly attached to the wooden board. Attached to.

According to the third aspect of the present invention, a retaining portion having a diameter larger than the diameter of the screw hole of the substantially U-shaped metal fitting is formed between the screw part of the rod-shaped lid support metal fitting and the wooden board contact part. Therefore, the substantially U-shaped bracket and the rod-shaped lid support bracket can be integrated, and in addition to the effects described in claim 1 or claim 2, the risk of losing each component is reduced.
