Description

[Detailed description of the invention] [Technical field] This invention relates to a hanging device for lighting equipment and the like.

[Background technology]

Conventional examples are shown in FIGS. 6 and 7. That is, conventionally, a shaft 32 is provided on the ceiling mounting plate 31 in order to enable it to be mounted on a sloped ceiling 30.
A shade 33 is rotatably attached to the shaft 32,
There was one in which the upper edge 33a of the shade 33 was inclined. 34 is flange, 35 is shade 3
3 is a hanging pipe attached to 3, 36 is a power line, 37
is a lamp.

However, there are restrictions on the inclination direction of the ceiling with respect to the ceiling mounting plate 31, and the shade 33 is cut diagonally to ensure an inclination angle of, for example, 30°, so if the ceiling construction material is not perpendicular to the inclination direction. were unable to use this equipment, and there were construction problems.

On the other hand, there was a hanging device in which a flange was attached to the ceiling, a spherical shade was brought into contact with the opening of the flange and supported rotatably, and a cord was hung from the center of the spherical shade. Application Publication No. 14482). This suspension device can eliminate the above-mentioned drawbacks, but when the spherical shade rotates, it is difficult for the spherical shade to rotate due to the frictional resistance of the contact surface between the spherical shade and the flange, and moreover, it slides in contact with the flange. The problem was that the surface of the shade was easily scratched and the appearance deteriorated.

[Purpose of invention]

The purpose of this invention is to provide a hanging device that allows the shade to be easily rotated and prevents the surface of the shade from being damaged.

[Disclosure of invention]

The hanging device of this invention includes a mounting member having a chain support hole formed therein, a hanging chain suspended in the chain support hole, a flange attached to the mounting member and forming a spherical support concave surface, and a flange formed with a spherical support concave surface. The suspension chain is provided with a spherical shade on which a convex rib is formed on the surface of the suspension chain, and the suspension chain hangs down.

According to the configuration of this invention, since the convex ribs are formed on the spherical shade, the strength of the spherical shade can be increased, and since the convex ribs are in contact with the spherical support concave surface of the flange and the spherical shade is supported by the flange, the spherical shade The frictional resistance between the shade and the spherical supporting concave surface of the flange is small, making it easier for the spherical shade to rotate, and since the surface of the spherical shade does not come into contact with the spherical supporting concave surface, it is possible to prevent the surface of the spherical shade from being damaged. The appearance of the spherical shade can be maintained well.

Example A lighting fixture to which an example of this invention is applied is shown in the first example.
This will be explained based on FIGS. In the figure,
The mounting member 1 has a disk shape, and as shown in FIG. A cut line 4 is provided between the intermediate height position of the support hole 3 and the outer edge of the cut and raised piece 2, and the upper piece 5 side thereof is bent to form a gap 7 larger than the wire diameter of the hanging chain 6. The suspension chain 6 has its upper end connected to the second
Tilt it as shown by the imaginary line in the figure, pass it through the gap 7, and suspend it from the chain support hole 3. As shown in Fig. 3, this mounting member 1 has four ceiling mounting holes 8 for mounting on the ceiling A, and these holes are made into long holes or pot-shaped holes so that the position can be easily adjusted. Screw 9 is hanging down. The flange 10 is passed through the caulking screw 9 and fixed with a cap nut 11. The edge of the central hole 10a of the flange 10 forms a spherical support recess surface 12.
2 supports the spherical shade 13, and the spherical shade 13 has a ring-shaped convex rib 14 formed on its outer periphery, and the convex rib 14 is brought into contact with the spherical support concave surface 12 by its own weight. In this case, the spherical center 15 of the spherical shade 13 is aligned with the position of the chain fulcrum of the chain support hole 3. Further, the lower part of the chain ring 6a at the upper end of the suspension chain 6 hangs down from the lower end hole 16 of the spherical shade 13.

A fixture main body 17 is attached to the lower end of the hanging chain 6, a plurality of hanging pipes 18 are provided on the fixture main body 17, and a lamp 22 having a lamp socket 19, a globe 20, and a lamp 21 is provided at the lower end of each hanging pipe 18. Installed.

The power supply wire 23 is drawn into the spherical shade 13 through a semicircular hole 24 formed by cutting and raising the cut and raised piece 2 of the mounting member 1, guided to the device body 17 along the hanging chain 6, and passed through the hanging pipe 18. It is connected to the lamp 22.

With this configuration, this hanging device has the following effects. That is, (1) the suspension chain 6 can be easily hung on the chain support hole 3 through the gap 7, and by attaching the flange 10, the suspension chain 6 can be easily hooked through the gap 7;
Since the inclination of the chain (imaginary line in FIG. 1) is restricted, the suspension chain 6 can be prevented from coming off. In this case, the case is not limited to the case where the chain ring 6a at the upper end hangs directly from the shade 13.

(2) A hanging chain 6 is attached to the spherical center 15 of the spherical shade 13.
Since the fulcrums are aligned, it can be installed on a sloped ceiling in any direction with a good appearance, as shown by the imaginary line in Figure 1.

(3) By supporting the convex ribs 14 of the spherical shade 13 on the spherical supporting concave surface 12, the strength of the shade 13 is increased, sliding friction resistance can be reduced, and damage can be prevented.

(4) Since the cutting and raising piece 2 is formed on the mounting member 1 and the power line 23 can be drawn in through the semicircular hole 24 formed by cutting and raising the piece 2, there is no need to separately provide a power line lead-in hole.

(5) The suspension chain 6 can be temporarily fixed by simply hooking it onto the chain support hole 3, and the power line 2
The wiring work in step 3 can be done with both hands.

[Effect of idea]

According to this invention, since the convex ribs are formed on the spherical shade, the strength of the spherical shade can be increased, and since the convex ribs abut against the spherical support concave surface of the flange and the spherical shade is supported by the flange,
The frictional resistance between the spherical shade and the spherical supporting concave surface of the flange is small, making it easier for the spherical shade to rotate, and since the surface of the spherical shade does not come into contact with the spherical supporting concave surface, it is possible to prevent the surface of the spherical shade from being damaged. This has the effect that the appearance of the spherical shade can be maintained well.
