Description

[Detailed description of the invention] This invention relates to lighting equipment such as a cord pendant.

Conventional examples include those shown in Figures 4 and 5, but the one shown in Figure 4 uses a shade 50 for cleaning etc.
When removing the hook ceiling cap 51 from the ceiling 5
It was troublesome that it had to be removed from the hook ceiling body 53 of No. 2. In the case of Fig. 5, when the nut 54 is loosened, the ring 5 of the shade 50
Although the shade 50 can be removed through a notch 56 formed in the notch 5, there is a risk that the nut 54 will loosen on its own due to vibrations, etc., and come off from the notch 56, causing the shade 50 to fall. 57 is a cord, 58 is an arm, 59 is a lamp socket, and 60 is a lamp.

Therefore, an object of this invention is to provide a lighting fixture whose shade can be safely and easily attached and detached.

An embodiment of this invention is shown in FIGS. 1 and 2. That is, in this lighting fixture, the lower piece 3 of the U-shaped folded cord guide 2 is attached to the upper surface of the top of the socket cover tube 1, which is the main body of the device, and the socket base 4 is attached to the lower surface of the top of the socket cover tube 1. Attach the rear end of the lamp socket 5 to the base 4. A threaded rod 6 is erected in the center of the lower piece 3 of the cord guide 2, cord insertion holes 9 and 10 are bored above the side piece 7 and in the center of the upper piece 8, and a regulating tube 11 is erected in the insertion hole 9. Pass the lower end of the hanging cord 12 through the regulating tube 11 and the cord insertion hole 10, and insert the side piece 7.
A guide piece 13 cut and raised is supported and guided into the interior through a hole 14 formed at the edge of the top of the socket cover cylinder 1, and connected to the lamp socket 5. In this way, the socket cover cylinder 1 is suspended from the ceiling by the cord 12. On the other hand, the shade 15 has a plurality of arms 16 projecting from the center from the upper opening edge, and the tips of the arms 16 are connected by a ring 17. Also arm 16
The space H between them is made large enough for the socket cover tube 1 to pass through. Pass the socket cover cylinder 1 between the arms 16 of this shade 15 and fit the ring 17 onto the threaded rod 6 of the cord guide 2.
and fix it by tightening the nut 18 on the threaded rod 6. Next, the upper cover 19, which has been passed through the cord 12 in advance, is lowered to cover the cord guide 2. 20 is a lamp.

In order to remove the shade 15 of this lighting fixture, it is sufficient to raise the upper cover 19, loosen and remove the nut 18, and pass the socket cover cylinder 1 between the arms 16.

FIG. 3 shows a multi-lamp lighting fixture, in which a cord guide 2' and a threaded rod 6' are attached to the upper surface of the fixture main body 22 that supports the lamp arm 21, and the space between the arms 16' of the shade 15' is Main body 22
and is sized to allow the lamp 23 to pass therethrough, and other aspects are the same as above. In addition, 24 is a switch string.

As mentioned above, in the lighting equipment of this invention, the ring supported by the arm of the shade is fitted into the threaded rod provided in the U-shaped cord guide and fixed with a nut, so it will not loosen unless the nut comes off. The effect is that the shade does not fall off, and the shade can be attached and detached safely and easily.
