る。 In this conventional example, a mounting base 12 having a U-shaped cross section is attached to a ceiling surface 1 with a nut 22, and a pair of through holes 12a are provided in the inner bottom surface of this mounting base 12. Further, a movable base 14 is provided below the mounting base 12 and has a pair of arms 15 facing downward on both sides, and the movable base 14 has a pair of through holes 14a.
is provided at a position corresponding to the through hole 12a of the mounting base 12. A lamp 16 is attached between the pair of arms 15 with bolts 17.
A pair of guide bolts 11 are fitted into the pair of through holes 12a of the mounting base 12, respectively, and the movable base 14 is attached along each of the pair of guide bolts 11 by two sets of coil springs 13 equipped with saucers 23 at both ends. Two sets of coil springs 13 and movable base 14 are supported by nuts 18 and 19 while sandwiching them.
Below the nuts 18, 19 are the nuts 18, 19.
A split pin 20 for preventing falling is provided to penetrate the lower part of the pair of guide bolts 11, respectively.
しかし、この従来例にはつぎのような問題点が
あつた。すなわち、ガイドボルト１１は可動台１
４の貫通孔１４ａを貫通しているため、振動の振
幅が大きくなると、それに伴う横方向の振動によ
つて貫通孔１４ａの周囲にガイドボルト１１ａが
当たつて衝撃が発生し、振動の吸収が良好に行え
ないという問題があつた。 However, this conventional example has the following problems. That is, the guide bolt 11 is connected to the movable base 1
Since the guide bolt 11a passes through the through hole 14a of No. 4, when the amplitude of the vibration becomes large, the accompanying lateral vibration causes the guide bolt 11a to hit around the through hole 14a, generating a shock, which makes it difficult to absorb the vibration. There was a problem that it was not working properly.
また、ガイドホルト１１が横方向の振動によつ
て貫通孔１４ａの周囲に当たりガイドボルト１１

たために部品の数が多くなり、構成が複雑で組立
性が悪いという問題があつた。 Further, the guide bolt 11 hits the periphery of the through hole 14a due to the lateral vibration, and the guide bolt 11
There have been problems in that the lamp 16 may fall due to breakage, or the lamp 16 may fall if the split pin 20 at the bottom of the guide bolt 11 is forgotten to fall, which is dangerous. Furthermore, since the coil springs 13 are disposed above and below the top plate 14, the number of parts increases, resulting in a complicated structure and poor assembly performance.

ため組立が容易でないという欠点があつた。 On the other hand, a coil spring is housed in a cylindrical flange, and the upper end of the pipe that passes through the coil spring and the hole at the bottom of the flange is supported by the upper end of the coil spring, and the lower end of the pipe that hangs from the flange is supported. Some were equipped with lighting equipment (for example, in the 1980s).
No. 19294). This lighting fixture has a simpler structure than the conventional example, and there is no danger of it falling, but if the lighting equipment swings beyond a certain angle, the pipe will collide with the edge of the hole in the flange, causing a shock. There were flaws. Furthermore, since the coil spring is inserted into the flange and the pipe is passed through the coil spring and the flange, assembly is not easy.
この考案の目的は、構造が簡単で落下の危険が
なく、しかも組立容易で振動による衝撃がない照

制されないので衝撃が発生しない。 According to the configuration of this invention, the approximately U-shaped mounting base and the approximately inverted U-shaped movable base are crossed with each other and a spring is interposed between them, making the structure simpler and easier to assemble than the conventional example. At the same time, since the movable base and the mounting base mutually guide each other, the movable base will not come off the mounting base even if the spring is damaged or the movable base moves horizontally, thus preventing the light from falling. There is no danger of In addition, since the mounting base is U-shaped, it is easy to install the spring, and the movable base can be mounted over the spring, making assembly easy.In addition, since the inverted U-shaped movable base covers the spring, the appearance is improved. Become good. Furthermore, even if there is vibration, the lamp can freely swing in any direction, forward, backward, left, or right using the spring as a fulcrum, and since the movement is not restricted by the mounting base, no impact is generated.

よつて固定されている。 The mounting base 2 has a hat-shaped cross section with mounting tongues formed at both ends of a substantially U-shape, and a nut 7 is attached to the ceiling surface 1.
It is attached by. The springs 3 are attached to four locations on the front, back, left and right of the spring mounting portion 2a.
The movable base 4 has a U-shaped cross section, and a pair of arms 5 are fixedly welded downward from both the front and rear sides of the movable base 4. A lamp 6 is attached to the lower part of the pair of arms 5 with bolts 8. One end of the spring 3 is pressed against the spring mounting portion 2a of the mounting base 2 by a plate member 9, and is fixed by a screw 10. Similarly, the other end of the spring 3 is a plate 9
It is pressed against the lower surface of the movable base 4 by a screw 10 and fixed by a screw 10.

きが規制されないので衝撃が発生しない。 According to this embodiment, since the substantially U-shaped mounting base 2 and the substantially inverted U-shaped movable base 4 cross each other and the spring 3 is interposed between them, the guide bolts, saucers, and splitters are different from the conventional example. Since parts such as pins are not required, the structure is simplified and assembly becomes easier.Since the movable base 4 and the mounting base 2 mutually guide each other, for example, the spring 3 may be damaged, or the movable base 4 may be moved horizontally. The movable base 4 does not come off from the mounting base 2 even if the light fixture 6 is moved, so there is no danger of the light fixture 6 falling. In addition, since the mounting base 2 is U-shaped, it is easy to install the spring 3, and the movable base 4 can be mounted so as to cover the spring 3, making assembly easy. Since the spring 3 is covered, the appearance is improved. Furthermore, even if there is vibration, the lamp 6 can freely swing in any direction, front, rear, left, or right using the spring 3 as a fulcrum, and since the movement is not restricted by the mounting base 2, no impact is generated.
