Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chandelier-type lighting fixture that has a small number of parts and has good operability at high places when removing an upper shade.

Conventionally, a chandelier-type lighting fixture having a plurality of round fluorescent lamps has a top plate 1 on which electric parts 1 and 8 for lighting the fluorescent lamps are attached to the end of a pipe-shaped arm 14, as shown in FIG.
6, an upper shade 2, a lower shade 13, and an arm force bar 15 attached to the top plate 16, and since there are many parts, assembly is troublesome and the cost is high.

In addition, the pipe-shaped arm 14 gets in the way, making it difficult to clean the upper shade 2.Furthermore, since the upper shade 2 is installed at a relatively high place, removal work is required when removing the upper shade 2 for cleaning. The drawback was that it was difficult.

The present invention was made to eliminate these drawbacks of the conventional example, and has a small number of parts, which simplifies the assembly work, and also improves operability at high places when removing the upper shade. The purpose of this invention is to provide a chandelier type lighting fixture.

This will be explained below using figures.

FIG. 1 is a perspective view of an embodiment of the present invention, FIG. 2 is a side sectional view of the same, and FIG. 3 is a perspective view of the upper shade seen from below.
In a chandelier type lighting fixture having a plurality of round fluorescent lamps 1, an upper opening groove 3 extending from the center to the outside of the periphery is integrally formed in the upper shade 2 of the round fluorescent lamp 1, and a groove 3 extending radially from the main body 4 is formed integrally with the upper shade 2 of the round fluorescent lamp 1. A glow lamp 7 for lighting a fluorescent lamp and electric parts for lighting the fluorescent lamp such as a ballast 3 are attached to the F side of a horizontal flat arm force bar 5 protruding from the upper opening groove 3. Two protrusions 10 that slidably support both side edges of the arm cover 5 at the upper end of the wall.
The arm cover 5 and the upper opening groove 3 are each provided with an engaging means so that the arm force bar 5 and the upper opening groove 3 are engaged with each other in a fitted state. be.

The engagement means is a leaf spring 1 provided on the upper surface of the arm cover 5.
1 and a hole 12 provided in the center of the upper shade 2, and at the position where the leaf spring 11 is fitted into the hole 12, the arm cover 5 is engaged with the upper opening groove 3. It looks like this.

Therefore, when attaching the upper shade 2 to the arm force bar 5, the both side edges of the arm force bar 5 are engaged between the two protrusions 10 formed in the upper opening groove 3 of the upper shade 2, and the upper shade 2 is attached to the arm force bar 5. It is sufficient to slide the shade 2 toward the arm cover 5 and push the upper shade 2 until the plate 11 serving as the engagement means is fitted into the hole 12.

At this time, the glow lamp 7 is arranged so as to be exposed inside the upper shade 2.

Similarly, when removing the upper shade 2 from the arm cover 5, just pull the upper shade 2 away from the arm cover 5, and the engagement between the plate 11 serving as the retaining means and the hole 12 will be released. The upper shade 2 can be easily removed by sliding the upper shade 2 and pulling it away from the arm force bar 5.

Therefore, compared to the conventional method of attaching the upper shade 2 using screws, etc., it is much easier to attach and remove the upper shade 2, and the operability at high places is extremely good. .

In the figure, 9 is a fluorescent lamp socket, and 13 is a lower shade.

The present invention is constructed as described above, and the upper shade 2 is attached to the arm cover 5 by engaging the two side edges of the arm cover 5 protruding from the main body 4 with the two protrusions formed on the upper shade 2. The upper shade 2 is fitted by sliding and is provided with a retaining means that engages the upper shade 2 with the arm force bar 5 at the position where the upper shade 2 is fitted into the arm force bar 5. It has the advantage of being easy to attach and remove, and has very good operability at high places.Moreover, when the upper shade 2 is removed, the electrical parts remain on the underside of the arm force bar 5, so the upper shade 2 can be washed completely. It has the advantage of being able to

In addition, since the hollow arm 6 can be configured by the upper opening groove 3 and the arm force bar 5 that are integrally formed with the upper shade 2, the number of parts is reduced, the assembly work is simplified, and the cost is reduced. It has advantages.

In addition, the arm force bar 5 and the upper opening groove 3 provided in the upper shade 2 can form a hollow arm 6 that is as strong and lightweight as the conventional pipe-shaped arm 14. Since the electrical parts 7 and 8 for the lighting circuit can be attached, there is an advantage that the top plate 16 is not required, and since the ballast is placed in the arm with good surrounding air convection, the heat dissipation efficiency is very good. There is an advantage.

In addition, the upper shade 2 is detachable, and the packaging can be made smaller, resulting in lower packaging costs and ease of transportation.
