Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a lighting equipment device in which a lighting equipment with a square flange is arranged on a ceiling surface in combination with a lifting device.

[Background technology]

Fig. 6 shows a state where a lighting fixture body 6 with a square flange on the outer periphery is suspended by a lifting device and placed on the underside of a ceiling 10, and the lighting fixture body 6 is placed offset (α in the figure) with respect to the vertical and horizontal lines of the underside of the ceiling 10. The lifting device is used by embedding it in the ceiling 10 of a general open-ceiling house, etc., but when the lighting fixture body 6 has a square flange part 6a (in the case of Fig. 6, a square ceiling downlight), it may be attached offset from the underside of the ceiling 10 as described above. This is because the lifting device is installed offset from the ceiling surface, or the mounting pitch and angle offset of the adjustment metal fittings, angle, and lighting fixture body 6 of the lifting device itself are accumulated, resulting in an overall angle offset. And once the lifting device is installed, there is a problem that there is no way to correct the angular flange part 6a of the lighting fixture body 6 when it is attached to the ceiling surface, such as when the scaffolding is removed.

[Purpose of invention]

The present invention has been proposed in view of the above-mentioned points, and it is an object of the present invention to provide a lighting equipment device that can easily and finely correct the angular deviation between the lighting equipment main body and the ceiling surface.

[Disclosure of invention]

(Structure) The present invention forms a pivot on the adjustment fitting of the lifting device in the ceiling, rotatably supports the slide fitting on this pivot, and further attaches the lighting fixture body to this slide fitting. The feature is that the angular deviation of the lighting fixture body relative to the ceiling surface can be slightly corrected.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIG. 5, the lifting device 1, which is equipped with a drum, a motor, a drive device, etc., is installed inside the ceiling 10 with bolts 21 through mounting brackets 12 protruding from both sides.
It is suspended. The depth of embedding of the lifting device 1 into the surface of the ceiling 10 is accurately determined by gauge fittings 4 protruding from both sides, and as shown in FIG. The elevating part 13 is suspended by a wire 5 wound around a drum or the like so as to be movable up and down. As shown in FIG. 3, a substantially U-shaped adjustment fitting 2 is attached to the elevating portion 13 via an angle 11 using screws 14 and spacers 15.

As shown in FIGS. 1 and 2, the adjustment fitting 2 is
Insertion holes 16 are formed at both ends thereof, and a curling hole 17 is formed at the center of the adjustment fitting 2. A convex portion 1 is formed around the upper side of this curling hole 17.
8 is formed, and this convex portion 18 serves as a pivot support for pivotally supporting a slide fitting 3, which will be described later. There are insertion holes 16 for the adjustment fitting 2 at both ends of the slide fitting 3.
A narrower insertion piece 19 is formed to be inserted into each. Further, a shaft support hole 20 is bored in the center of the slide fitting 3 and is inserted into the convex portion 18 of the curling hole 17.
The slide fitting 3 is inserted into the adjustment fitting 2 so that it can rotate freely with respect to the adjustment fitting 2. Furthermore, pitch holes 23 are formed on both sides of the slide fitting 3 for attaching the lighting device main body 6. Further, a long hole 24 for screw escape is bored in the adjustment fitting 2 in correspondence with the pitch hole 23.

As shown in FIG.
6, and while pushing the other insertion piece 19, which is raised by the protrusion 18 of the curling hole 17 at the center of the adjustment fitting 2, in the direction a in the figure,
When moving in direction b, by fitting the shaft support hole 20 into the convex portion 18 of the curling hole 17 and fitting both insertion pieces 19 into the insertion hole 16, the slide fitting 3 is fitted into the adjustment fitting 2.
It can be inserted into. At this time, since there is a shaft support hole 20 in the center of the slide fitting 3 that is large enough for the convex portion 18 to enter, the slide fitting 3 can be easily bent in the direction a. Convex part 1 after fitting
8 serves as a shaft support, and the slide fitting 3 moves β in the circumferential direction.
It can be rotated by an angle. Next, as shown in FIG.
is attached to the slide fitting 3 by screwing it into the pitch hole 23 of the slide fitting 3. When finely adjusting the angle misalignment between the lighting fixture body 6 and the ceiling surface, first screw 9.
Loosen the screws 9 and rotate the lighting fixture body 6 to match the ceiling surface to adjust the angle deviation. After adjustment, tighten the screws 9.
Tighten to secure it to the slide fitting 3 and adjustment fitting 2. Incidentally, the lamp 7 of the lighting fixture main body 6 is provided with a rectangular shade 8. In this way, the slide metal fitting 3 can be attached to the adjustment metal fitting 2 with one touch without screws so that it will not come off, and after the slide metal fitting 3 is fitted into the adjustment metal fitting 2, the curling hole 17 of the adjustment metal fitting 2 can be attached to the slide metal fitting 3. The slide fitting 3 is guided, the angle of the square flange can be adjusted, and
The angle can be adjusted by simply loosening the screw 9.

[Effect of idea]

As mentioned above, the present invention consists of an elevating device installed in the ceiling, an elevating section that can be moved up and down by the elevating device, and a lighting fixture body that is attached to the elevating section and placed on the lower surface of the ceiling. In this lighting equipment device, a slide fitting is rotatably supported on a shaft support formed in the adjustment fitting of the lifting part, and a lighting equipment main body having a square flange on the outer periphery is attached to the slide fitting. This has the advantage that the angle of the rectangular flange of the lighting fixture body with respect to the ceiling surface can be easily adjusted by simply rotating the slide fitting to which the lighting fixture body is attached.
