Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a lighting fixture having a shade divided into two upper and lower stages.

Conventional configurations and their problems Conventionally, in chandeliers, hanging lighting fixtures, etc., the shade attached to the main body is divided into two levels, upper and lower, and lamp replacement is facilitated by removing only the lower shade. However, since the upper shade was simply placed on the top of the main body, the upper shade was easy to lift up, and when cleaning the shade, it was difficult to clean. It is easy to get detached from the main body and climb onto the top surface of the main body, causing it to become misaligned.Especially in the case of a chandelier, where multiple lights are suspended with a balanced weight, one of the shades may become misaligned. There were problems such as the overall weight balance being disturbed, causing the product to tilt, resulting in complaints from customers.

OBJECTS OF THE INVENTION The present invention takes into account the above problems and aims to provide a lighting fixture that properly fixes the shades.

Structure of the Invention In order to achieve this object, the present invention targets a round body, and attaches a plurality of shade fittings having outward engagement grooves formed on the outer periphery of the body at appropriate intervals, A plurality of inward convex pieces are formed on the circular hole edge of the first shade located on the upper side and are inserted between the shade fittings and rotated to be engaged with the engagement groove, and the first shade is formed on the lower side. By attaching the center of the lower surface of the second shade to the lower end of the main body, the upper edge of the second shade engages with the lower edge of the first shade, thereby pushing up the first shade and causing the protrusion. The lighting device has a structure in which the upper surface of the piece is brought into contact with the upper surface of the engagement groove, and this structure prevents the first shade from floating and practically prevents rotation of the first shade by the abutting action. It is something that makes it possible. Furthermore, in the present invention, a flange is formed on the outer periphery of the round main body, and the shaded fitting has an inward mounting groove below the engagement groove, and this mounting groove allows the flange to be moved up and down. attached to the flange portion so as to be sandwiched therebetween;
Lamp holders supporting the annular lamps are attached to the flanges with screws together with the shade fittings, and the projecting piece of the first shade can be inserted from below between the shade fittings. .

DESCRIPTION OF EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

The drawing shows a part of the chandelier, in which a horizontal arm 2 extends to the side of a central hanging device 1, and the upper surface of a round main body 3 is supported at the end thereof. This main body 3 is constructed by combining two plate-shaped sheet metal members divided into upper and lower parts, and houses a stabilizer 4 inside. The main body 3 has a flange 5 formed on its outer periphery, and a plurality of shade fittings 6 molded from synthetic resin and having a substantially S-shaped cross section are attached to the flange 5 at appropriate intervals. This shade fitting 6
An outward facing engagement groove 7 is formed therein, and an inward facing mounting groove 8 is formed below the engaging groove 7, and the collar part 5 is attached to the collar part 5 so as to be sandwiched therebetween from above and below. The main body 3 includes the same number of lamp holders 9 made of sheet metal as the shade fittings 6, and the lamp holders 9 are attached to the main body 3 at the same time as the shade fittings 6 using screws 10. For this installation, for example, the installation groove 8 has an insertion hole 11 into which the base of the lamp holder 9 is inserted, and the screw 10 is inserted into the installation groove 8 from below and screwed into the flange 5 through the base of the lamp holder 9. This is due to Reference numeral 12 denotes a first shade made of synthetic resin, which includes a plurality of inward convex pieces that are inserted from below between the shade fittings 6 and engaged with the engagement grooves 7 by rotating (arrow in FIG. 3). 13 is formed on the edge of the circular hole 14. In the case of a chandelier, this first shade 12 can be attached from below because it has an arm 2. Since there is a convex piece 13, it is necessary to attach the first shade 12 to the flange part 5 by lifting it obliquely upward while making it eccentric to the center of the main body 3. You can do this after positioning it above.
Reference numeral 15 denotes a second shade made of synthetic resin, and by attaching the center of its lower surface to the lower end of the main body 3 with, for example, a decorative screw 16, the upper edge engages with the lower edge of the first shade 12. By pushing up this first shade 12 and bringing the upper surface of the convex piece 13 into contact with the upper surface in the engagement groove 7, this first
The structure is such that the lifting of the shade 12 is prevented and rotation of the first shade 12 can be practically prevented by the abutting action without the need for a separate return prevention mechanism. The main body 3 includes a fitting 17 for the second shade 15 at its lower end, and the second shade 15 is attached via the fitting 17. Further, one end of the convex piece 13 has a small protrusion 18, so that when the first shade 12 is rotated, the convex piece 1
3 is brought into contact with the outer edge of the engagement groove when it is most appropriately engaged with the engagement groove 7, thereby preventing the first shade 12 from being turned too much. Further, 19 is an annular lamp supported by the lamp holder 9.

It should be noted that an embodiment in which the main body 3 does not have the fitting 17, the lower end of the main body 3 is configured to bulge downward, and the second shade 15 is attached to the lower end is also possible.

Effects of the Invention As is clear from the above explanation, the lighting equipment of the present invention is configured to appropriately prevent the shade from rising while following the basic usefulness of the shade divided into two upper and lower stages. This has the effect of preventing the shade from shifting its position during cleaning, and preventing the overall weight balance from being disturbed and tilting, especially in the case of a chandelier. These effects are unique to the engagement relationship between the upper and lower divided shades, and are generally not effective at all when one shade is attached using something similar to the shade fitting, which is a component of the present invention. This is clearly different from the advantage of the present invention.

In addition, in the present invention, by attaching the inwardly directed mounting groove at the bottom of the shade mount to the flange on the outer periphery of the main body, the lamp holder can be attached to the main body at the same time as the shade mount. Attaching it provides effects such as improved workability. Furthermore, in the present invention, since not only the second shade but also the first shade which is located above the second shade and is in an engagement relationship with the shade fitting is attached and removed from below the main body, a sideways arm is provided on the upper surface of the main body. It is also useful and convenient when the first shade cannot be attached or detached from above the main body. Furthermore, since it is only necessary to newly install a shade fitting without modifying the main body, a main body of another type can be used, and investment costs can be extremely reduced.
