Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in lighting fixtures, and particularly to a globe mounting structure for chandelier-type lighting fixtures.

Conventionally, there are various mounting structures for globes in chandelier type lighting equipment. For example, the first
As shown in the figure, a groove-shaped slit 2 is formed in the upper component wall of the lighting fixture body 1, and a globe mounting bracket 4 having a step 3 is supported in the slit 2 with a knurled screw 5. A mounting portion 7 of the glove 6 is sandwiched between the lower surface and the glove mounting bracket 4.

However, according to the same structure, if the knurled screw 5 loosens due to vibration, there is a risk that the outer end of the glove fitting 4 will fall downward and the glove 6 will fall.

The present invention has been devised in view of the above points, and an object of the present invention is to provide a lighting fixture that can reliably support a glove for a long period of time even when the lighting fixture vibrates.

The present invention will be explained below with reference to FIGS. 2 and 5. In the figure, reference numeral 11 denotes a lighting fixture main body, and slits 13, some of which have large-diameter portions 12, are formed at a plurality of locations in the upper constituent wall. Reference numeral 14 denotes a glove attachment fitting, which has a stepped portion at its outer end and is provided with a glove support portion 15, has a tapered portion 16 at its inner end corresponding to the large diameter portion 12 of the slit 13, and is locked at its tip. A portion 17 is formed, and a threaded portion 18 is formed approximately in the center. Reference numeral 19 denotes a knurled screw that passes through the slit 13 of the lighting fixture body 11 and supports the globe attachment fitting 14 on the lighting fixture body 11. 20 is a glove, and a mounting part 21
is configured to be held between the outer lower surface of the lighting fixture body 11 and the globe support portion 15.

For example, the lighting fixture configured as described above is
As shown in the figure, multiple units are supported on the mounting arm of a chandelier type lighting fixture.

Next, support for the globe in the lighting fixture having the above structure will be explained. The lighting fixture main body 11 is brought into contact with the globe 20, and the globe mounting bracket 14 is supported in a proper position in the slit 13 of the lighting fixture main body 11 with a knurled screw 19. Also knurled screw 1
After screwing into the threaded portion 18 of the glove fitting 14, the tip 9 is caulked to prevent it from falling off.
In the same structure, the glove fitting 14 gradually moves from the inside of the slit 13 to the outside, and the enlarged portion 1 of the glove fitting 14 is attached to the large diameter portion 12 of the slit.
When 7 is positioned, tighten the knurled screw 19,
The globe 20 is attached to the lighting fixture body 11.

Also, due to the vibration of the lighting equipment, the knurled screw 1
9 becomes loose, the tapered part 16 of the glove fitting 14 engages with the wall surface of the large diameter part 12 of the slit 13 according to the degree to which the knurled screw 19 has loosened, and the glove fitting 14 does not tilt more than a certain level, and the glove fitting 14 does not incline more than a certain level. 20 can be prevented from falling off.

As described above, the present invention includes a slit that partially has a large diameter part in the upper component wall of the lighting fixture body, has a globe support part at the outer end, and has a large diameter part of the slit at the inner end. It has a correspondingly tapered part and a locking part at the tip to constitute a glove mounting bracket,
The globe mounting part is held between the outer lower surface of the lighting fixture body and the globe support part, and the tapered part of the globe mounting bracket engages with the large diameter part of the slit and moves up and down, so as mentioned above, Even if the knurled screw supporting the glove fitting becomes loose, the glove fitting does not tilt more than a certain level, which has the advantage of preventing the glove from falling off.
