[0012]

1 and 2 show a first embodiment of a mounting structure for an implantable electric appliance according to the present invention. Instrument 1
It is designed to be attached to two suspension bolts 2 hanging from a ceiling structural member by two suspension tools 3.

The electric device 1 is, for example, a lighting device,
Instrument main body 1a inserted into an embedding hole provided in the ceiling
However, it is configured to include an angle-shaped portion 1b having a substantially U-shape in a front view, and a substantially cylindrical side wall 1d fixed to a lower end thereof and provided at its lower end with an outer flange 1c contacting the lower surface of the ceiling. .
And a plurality of 4 is provided on the side wall 1d of the device main body 1a.
The two engaging holes 1e are provided at a substantially equal pitch in the circumferential direction of the side wall 1d.

The hanging member 3 is formed of a rectangular plate, and has a bolt mounting hole 3a formed at a substantially central portion thereof where the hanging bolt 2 is inserted. The bolt mounting piece 3b is disposed substantially horizontally.
A pair of connecting pieces 3d extending diagonally downward from both ends of one side end of the bolt mounting piece 3b, and provided at the tip of the connecting piece 3d to be bent to the side opposite to the bolt mounting piece 3b; An engaging claw 3c that is inserted into and engaged with an engaging hole 1e provided in a side wall 1d of the instrument body 1a. Each of the engaging claws 3c is adapted to engage with a pair of adjacent engaging holes 1e provided in the side wall 1d, and one hanging member 3 has a bolt mounting piece having one bolt mounting hole 3a. 3b and a pair of engaging claws 3c are provided.

In such an embedded electric appliance, the two suspension bolts 2 attached to the back surface near the periphery of the recessed hole in the ceiling so as to hang down from the ceiling structural material are respectively connected to the bolts of the suspender 3. Insert the claw 3c through the mounting hole 3a.
Is attached outward and temporarily fixed, and the engaging claw 3c is inserted from the inside of the side wall 1d of the instrument body 1a into the engaging hole 1e of the side wall 1d to be engaged therewith, and the outer flange 1c is attached to the lower surface of the ceiling. Tighten the nut (not shown) until it comes into contact with.

With such a configuration, the mounting structure of the implantable electric appliance according to the present embodiment has
One hanging tool 3 includes one bolt mounting hole 3a and a plurality of two engaging claws 3c, and a side wall 1d of the instrument body 1a.
Of the plurality of engagement holes 1e provided in the pair of engagement holes 1
e, the number of the suspension bolts 2 for attaching one electric appliance 1 can be reduced, and the workability when the suspension bolts 2 are constructed on the building is improved. In addition, since the number of the suspension bolts 2 when attaching one electric appliance 1 may be small, a shift in pitch between them is easily absorbed, and
Further, since the number of nuts to be tightened is reduced, the workability is also improved.

FIG. 3 shows a main part of a modified example of this embodiment. The difference from the above-described embodiment is that the bolt mounting hole 3a is formed as a long hole-shaped daruma hole. The other configuration is the same as that of the present embodiment. Even with such a configuration, the same effects as those of the embodiment shown in FIGS. 1 and 2 can be obtained, and the variation in the pitch of the suspension bolts 2 in the longitudinal direction of the bolt mounting holes 3a can be easily absorbed.

FIG. 4 shows a main part of a second embodiment of the mounting structure for an implantable electric device according to the present invention. The difference from the first embodiment is that the engaging claw 3c is provided. And the bolt mounting piece 3b are formed so as to protrude in the same direction from the connecting piece 3d, and the other configuration is the same as that of the first embodiment. Even with such a configuration, the same effects as those of the first embodiment can be obtained, and the bolt attachment piece 3b of the hanging member 3 has the engagement claw 3c inserted into the engagement hole 1e from inside the side wall 1d. In this state, the bolt mounting piece 3b faces the outside of the instrument main body 1a, so that the bolt mounting piece 3b is less likely to obstruct components such as a reflection plate housed inside the instrument main body 1a.

FIG. 5 shows a third embodiment of the mounting structure for an implantable electric device according to the present invention. The difference from the first embodiment is that the fishing tackle 3 is attached by bolts. Piece 3b
Are formed by providing four connecting pieces 3d from both sides of both side ends of each of them, and providing an engaging claw 3c outward at the tip thereof. Others are the same as in the first embodiment. It is configured. With such a configuration, the same effects as those of the first embodiment can be obtained, and the number of the suspension bolts 2 can be further reduced, so that the workability is further improved.

It should be noted that, in the present embodiment, the hanger 3
Has been described as one hanging tool 3 having four engaging claws 3c, but the present invention is not limited to this, and a long connecting piece of the hanging tool as shown in the first embodiment is formed. Alternatively, the bolt mounting pieces of the two hanging tools may be overlapped with the connecting piece on the outside, and may be attached to one hanging bolt.

[0021]

According to the present invention having the above-described structure, one of the hanging members is
One electric appliance is provided with one bolt mounting hole and at least one pair of engaging claws to engage with at least one pair of engaging holes of the plurality of engaging holes provided on the side wall of the appliance main body. The number of hanging bolts for mounting can be reduced,
Improves workability when installing suspension bolts on buildings.
In addition, since the number of suspension bolts when attaching one electric appliance may be small, a shift in pitch between them is easily absorbed, and the number of nuts to be tightened is reduced.
Its workability is also improved.

According to the second aspect of the present invention, a first aspect is provided.
In addition to the effects of the invention described above, since the bolt mounting hole is a long hole, it is easy to absorb variations in the pitch of the suspension bolts in the long direction.

According to the third aspect of the present invention, in addition to the effects of the first or second aspect, the bolt mounting piece of the hanging tool has an engaging claw having an engaging hole from the inside of the side wall. In the state inserted into the device main body, the bolt mounting piece is directed to the outside of the device main body, so that the bolt mounting piece is less likely to interfere with components housed inside the device main body.
