DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to embodiments. Embodiment 1 FIG. 1A is an exploded perspective view of a fixture 3 in the present embodiment. The attachment 3 is formed in an arch shape by providing flat mounting portions 3a at both ends. In order to increase the strength, the edge of the mounting member 3 is bent upward, and a fixing bolt hole 3b formed in an elongated hole shape for inserting and fixing the bolt 4 substantially in the center of the mounting member 3. Is provided. On the other hand, as shown in FIG. 1 (b), the thread 4a of the bolt 4 is chamfered on both sides along the direction of travel of the screw, and is a cross section obtained by cutting the thread 4a by a plane perpendicular to the direction of travel of the screw. The shape matches the shape of the fixing bolt hole 3b. Then, the bolt 4 is inserted into the fixing bolt hole 3b from the upper side of the fixture 3, and the nut 5 is screwed into the bolt 4 from the lower side of the fixture 3 to securely fix the bolt 4 to the fixture 3. . At this time, since the sectional shape of the bolt 4 matches the shape of the fixing bolt hole 3b, the fixture 3 can be turned integrally with the bolt 4.

Then, the bolt 4 fixed to the fixture 3
Is inserted through a spring 6 for elastically supporting the fixture 3, and the bolt 4 is passed through a bolt hole 2 a provided in the main body upper cover 2 of the ceiling-mounted lighting fixture 1, and a substantially disc-shaped washer 7 is inserted. The mounting fixture 3 is attached to the main body top cover 2 by tightening with a butterfly nut 8 through.
An elongated bolt locking hole 7 provided substantially at the center of the washer 7.
Since a is matched with the sectional shape of the bolt 4, the washer 7 can also be rotated integrally with the bolt 4. Further, a cut is made in a substantially trapezoidal shape from the edge of the washer 7 toward the center and bent downward, and two bent pieces 7b are provided substantially symmetrically with respect to the bolt locking hole 7a. That is, the bent piece 7 of this washer 7
b is an operation knob.

In order to mount the recessed ceiling lighting fixture 1 with the mounting fixture 3 attached as described above to the recessed hole 10 provided in the ceiling material 9a of the ceiling 9, the following procedure is performed.
First, as shown in FIG. 2A, the mounting fixture 3 is rotated so that the mounting portion 3a is positioned on the main body upper cover 2, and the main body upper cover 2 of the ceiling-mounted lighting device 1 is removed. Embed in the embedding hole 10. At this time, the attachment 3 is pushed upward and supported by the spring 6, and the distance between the attachment 3 and the main body upper cover 2 is kept substantially constant. Therefore, the main body top cover 2 can be easily embedded in the embedding hole 10.

Next, the bent piece 7b of the washer 7 is operated by hand,
As shown in FIG. 2B, the mounting fixture 3 is rotated to a position where it bridges the embedding hole 10, and the mounting portion 3a is mounted on the back surface of the ceiling material 9a to mount the mounting fixture 3. Then, the main body top cover 2 is tightened by tightening the butterfly nut 8.
Of the ceiling hole 9a, and the ceiling-embedded lighting fixture 1 can be attached without any gap according to the thickness of the ceiling material 9a. Also, the ceiling member 9a is formed by the mounting portion 3a of the fixture 3 and the main body top cover 2.
And the ceiling-embedded lighting fixture 1 can be fixed to the ceiling 9.

(Embodiment 2) In this embodiment, the basic configuration is the same as that of Embodiment 1, and the description of the common parts will be omitted. First, as shown in FIG. 3, the mounting tool 11 in this embodiment has the mounting portions 11a at both ends thereof bent upward by an angle θ. The fixture 11 is attached to the main body top cover 2 of the ceiling-mounted lighting fixture 1 in the same manner as in the first embodiment.

FIG. 4 is a view in which the upper cover 2 of the main body of the above-described ceiling-embedded lighting fixture 1 to which the fixture 11 is attached is attached to the embedding hole 10 provided in the ceiling material 9a.
A ceiling member is disposed on the back side of the drawing a and on one side near the embedding hole 10. The ceiling member is, for example, a so-called M bar 12 which is formed of a metal such as aluminum and has a substantially M-shaped cross section. In the case described above, since one mounting portion 11a of the fixture 11 is placed on the M bar 12 as shown in FIG. 4, the fixture 11 is inclined with respect to the ceiling 9. Fixed. However, since the end of the mounting portion 11a is bent upward by the angle θ, the bent portion 11b can make surface contact with the ceiling material 9a. Therefore, it is possible to prevent the ceiling material 9a from being damaged by the edge of the mounting portion 11a of the fixture 11 that is fixed in an inclined manner.

Note that, as shown in FIG.
Even if M bars 12 are arranged on both sides of the
a can be placed on the M bar 12 to mount the fixture 11. (Embodiment 3) FIG. 6 shows a main part of a fixture 13 in this embodiment. In the figure, reference numeral 14 denotes a mounting portion, which is formed by bending both ends to the same side at substantially right angles. And the mounting fixture 13
From the center of the mounting portion 14,
A point moved in the vertical direction with respect to the main body top cover 2 is a fulcrum 15, and two mounting portions 14 are rotatably supported at both ends thereof. The edge of the fixture 13 is bent inward in order to increase the strength similarly to the first embodiment, and the fixture 13 is attached to the main body upper cover 2 of the ceiling-mounted lighting fixture 1 in the same manner as the first embodiment. It is attached.

FIG. 7 is similar to the case described in the second embodiment.
This shows a case where the M bar 12 is provided on the back surface of the ceiling material 9a, on one side near the embedding hole 10. In the fixture 13 of the present embodiment, the mounting portion 14 is
3, and the fulcrum 15 moves vertically from the approximate center of the mounting portion 14 with respect to the main body upper surface cover 2 of the ceiling-mounted lighting device 1. Part 1
By rotating the mounting 4 by 180 degrees, the height of the mounting portion 14 when the mounting portion 14 is mounted on the back surface of the ceiling 9 can be selected in two ways. Therefore, as shown in FIG. 7, by increasing the height of the mounting portion 14 mounted on the M bar 12 side, one of the mounting portions 14
Even when it is placed on the ceiling, the recessed ceiling lighting fixture 1 can be fixed to the ceiling 7 without tilting the fixture 13.

(Embodiment 4) FIG. 8 shows a fixture 18 in this embodiment. The attachment 18 includes a support plate 19 and a mounting portion 20. The mounting portion 20 is formed by bending both ends of a plate-like member in opposite directions. The support plate 19 is provided with a moving elongated hole 19a symmetrically with respect to a fixing bolt hole 19b provided substantially at the center, and the mounting portion 20 and the support plate 19 are screwed through the moving elongated hole 19a. The mounting portion 20 can be moved in parallel by the length of the moving slot 19a. The mounting fixture 18 is attached to the main body top cover 2 of the ceiling-mounted lighting fixture 1 in the same manner as in the first embodiment.

In this embodiment, as shown in FIG.
When the main body top cover 2 of the ceiling-mounted lighting device 1 does not protrude to the rear surface side of the ceiling 9, the mounting portion 20 on the side where the M bar 12 is provided is moved in parallel, and the M bar 12 and the mounting portion are moved. The mounting portion 21 can be mounted on the back surface of the ceiling 9 by shifting the positional relationship with the ceiling 21, and the embedded ceiling lighting fixture 1 can be fixed to the ceiling 9 without tilting the fixture 18.
