The inner ring 2 includes a vertical frame portion 21 that faces the vertical frame portion 31 of the outer ring 3 via the hollow portion 10, and a flange portion 2 that extends horizontally above the vertical frame portion 21.
As shown in FIGS. 4 and 6, the flange portion 22 is provided with an insertion slot 24 for a screw member 6 constituting the tightening member of the present invention. Reference numeral 5 denotes a pair of elastic engagement pieces provided opposite to the insertion slot 24 of the inner ring 2, with an elastic spring part 51 rising from the inside of the vertical frame part 21 and a spring part 51 extending horizontally to the locking step part 32. It consists of a tightening piece 52 that comes into pressure contact, and a guide piece 53 that guides the tightening piece 52 up and down along the inside of the locking step 32. In the case of the example,
The lower end portion of the elastic spring portion 51 is fixed to the inner lower end portion of the vertical frame portion 21 of the inner ring 2 by spot welding. As shown in the third diagram, the elastic spring portion 51
is curved inward when no external force is applied so that the outer ends of the tightening piece 52 and the guide piece 53 can be inserted inside the outer ring 3, and as shown in the second figure, the inner The outer end portion of the tightening piece portion 52 is configured to come into pressure contact with the locking step portion 32 of the outer ring 3 when the tightening piece portion 52 is bent in close contact with the inside of the ring 2 . Furthermore, a screw hole 52a is bored approximately in the center of the tightening piece portion 52 of the elastic engagement piece 5, into which the screw shaft portion of the screw member 6 is screwed through the insertion slot 24 from the hollow portion 10. When the screw member 6 is tightened, the locking step 32 of the outer ring 3 is held between the screw head and the tightening piece 52, fixing the inner ring 2, and when the screw member 6 is loosened slightly, When the inner ring 2 is made rotatable with the outer end of the tightening piece 52 in contact with the locking step 32 and further loosened, the outer end of the tightening piece 52 comes into contact with the locking step 32, as shown in FIG. 32 so that the inner ring 2 can be removed. In the embodiment, the elastic engagement pieces 5 and the insertion grooves 24 are only provided at two locations on the inner ring 2, but the number is not limited to two, and it is of course possible to provide more than two locations. In addition to the above-mentioned embodiments, the structure of the tightening member according to the present invention includes using a washer 25 that abuts the lower surface of the locking step 32 on the screw member 6, as shown in FIGS. 4 and 5. Alternatively, a collar piece 25 may be provided on the lower surface of the flange portion 22 to contact the lower surface of the locking step portion 32, or as shown in FIGS. 6 and 7, the flange portion 2
The outer peripheral edge of the ring 2 is configured to have a size that abuts the lower surface of the locking step 32, so that when the inner ring 2 is attached to the outer ring 3, the flange portion 22 does not go beyond the locking step 32 and enter into the inside. It is also possible to make the rotation operation smoother.

In addition, in FIGS. 1 and 2, 8 is an inner ring 2 and an outer ring 3 of the device of the present invention.
A pair of opening leg springs 8a provided in the diametrical direction on the inside of the decorative plate are inserted into the engagement elongated hole 26 (fourth
It is attached by being latched onto the body (as shown in Figures 6 and 6).

To explain how to use the device of the present invention having the above-mentioned configuration, when installing a lighting device, first, the frame body 34 that is integrated with the outer ring 3 is fitted into the mounting hole 4, and the ceiling plate 7 is fixed to the spring plate with the mounting tool 35. 35a and the flange portion 33 of the outer ring 3 to clamp and fix. Next, the illuminator main body 1 and the inner ring 2 are inserted into the mounting hole 4. At this time, if the screw member 6 is loosened, the elastic engagement piece 5 provided on the inner ring 2 is in an inwardly curved state, so that the outer ends of the tightening piece part 52 and the guide piece part 53 can be It can be inserted without getting caught on the locking step 32 of the ring 3. Thereafter, as the screw member 6 is tightened, the screw member 6 gradually stands up vertically in the hollow portion 10, and the locking piece 52 of the elastic engagement piece 5 bends horizontally to lock the outer ring 3. It comes into contact with the stepped portion 32. In this state, the illuminator body 1 can be rotated together with the inner ring 2, so by using it together with the rotation around the support shaft 23 with respect to the inner ring 2, it is possible to illuminate any direction, making it a universal downlight. It can be used as a. Further, by tightening the screw member more strongly, the locking step portion 32 is held between the head of the screw member 6, the collar piece 25, or directly between the flange portion 22 and the locking piece 52, and the inner ring 2 is strongly fixed to the outer ring 3, and the illuminator can be fixed in a desired direction. Finally, the decorative panel 8 closes the opening leg spring 8a against its spring elasticity and pushes it into the attachment elongated hole 26 of the inner ring 2, and the outer ring 3 and the inner ring 2 are closed by the spring elasticity of the opening leg spring 8a. Can be installed covered.

As described above, according to the device of the present invention, an outer ring is fixedly installed along the inner circumference of a mounting hole drilled in a ceiling plate for mounting a lighting device, and a ring-shaped continuous ring is attached to the upper end of the outer ring. A stopping step is provided, and an inner ring is provided inside the outer ring to face each other concentrically through a hollow portion, and an illuminator is attached to the inner ring so as to be tiltable, and is crimped to the stopping step. An elastic engagement piece having spring elasticity that can be deflected between a position and a retracted position along the inside of the locking step is attached to the inner ring, and the elastic engagement piece is attached to the locking step. Since the structure has a structure in which a tightening member for crimping and locking the inner ring is provided within the hollow part, the main body of the illuminator such as a downlight can be attached to the inner ring so as to be tiltable about the uniaxially supported spindle, and the The inner ring can be freely attached to and detached from the outer ring fixed to the illuminator mounting hole, and the elastic engagement piece provided on the inner ring can be attached to the outer ring by the tightening member in the hollow space between these rings. By crimping the locking step part of the ring and adjusting the tightening strength, it is possible to easily rotate and fix the illuminator.
