Description

[Detailed Description of the Invention] The present invention mainly relates to a lighting fixture in which a glass globe is attached to the fixture body, and is intended to prevent the globe from cracking and to absorb variations in molded dimensions.

Glass globes tend to vary in their molded dimensions and are highly likely to break if not handled carefully, so it is necessary to use some kind of cushioning member to attach them to the instrument body.

Conventionally, rubber has been used as this cushion member, but there is a risk of deterioration over time, and stable attachment over a long period of time could not be expected.

Furthermore, it has been almost impossible to effectively absorb large dimensional variations.

The present invention solves the above-mentioned drawbacks, and examples thereof will be described below.

In FIG. 1, 1 is the instrument body, and 2 is a reflective plate extending from the instrument body, forming an annular shape.

3 is a glass globe, the mouth edge of which is engaged with the edge of the reflecting plate 2.

A support rod 5 protruding from the instrument body 1 is inserted into a center hole 4 formed at the top of the glass globe 3, and a thumbscrew 6 is attached to a portion of the support rod 5 protruding outward from the globe.
are screwed together.

The support rod 5 passes through a spring 8 housed inside a support rod storage fitting 7 having a U-shaped cross section and protruding from the instrument body 1, and the bottom surface of the support load storage fitting 7, and projects downward.

Further, a rotation stopper 9 is attached to the other end of the support rod 5 located inside the support rod storage fitting 7.

FIG. 2 shows the relationship between the support rod 5 and the support rod storage fitting 7. As shown in FIG.

In addition, in FIG. 1, 10 is a lamp, 11 is a support spring, 12 is a stabilizer, and 13 is a hanging metal fitting.

In the above configuration, when attaching the glass globe 3, the mouth edge of the glass globe 3 is fitted and engaged with the edge of the reflector 2, and the support rod 5 is inserted into the center hole 4.
and insert a thumbscrew 6 into the tip of this support rod 5.
Screw them together.

At this time, since the rotation stopper 9 attached to the upper end of the support rod 5 compresses the spring 8 downward, the support rod 5 moves downward.

When the support rod 5 is completely tightened, the tip end surface of the support rod 5 comes into contact with the bottom surface of the tapped hole of the thumbscrew 6 and stops.

Further, since the support rod 5 does not rotate due to the rotation stopper 9, the thumbscrew 6 can be tightened.

Next, another embodiment will be described.

In FIG. 3, the support rod storage fitting 7' has a rectangular cylindrical shape, and the rotation stopper 9' has a rectangular shape.

Fig. 4 uses a curved spring 8', but since the height cannot be increased like a coiled spring, the support rod 5 must be prevented from being pulled out so that it does not get inside the support rod storage fitting 7. A ring 14 is used.

FIG. 5 shows an example in which another component is compressed by 6, and a spindle-shaped rubber tube 15 is inserted through the tip of the support rod 5.

This rubber tube 15 slightly protrudes from the tip of the support rod 5 when the glass globe 3 is not attached.

This state is shown in FIG. With this configuration, there is almost no possibility that the tip of the support rod 5 will hit the periphery of the center hole 4 of the glass globe 3 and cause a crack during assembly, and the probability of breakage during assembly can be almost eliminated.

Further, during assembly, the rubber tube 15 is pushed in around the center hole 4 and bulges laterally, so that the thumbscrew 6 can be screwed into the tip of the support rod 5.

As described above, the present invention is mainly used to absorb fluctuations in the height h (Fig. 1) of the glass globe and to prevent cracking when the glass globe is tightened with a thumbscrew.
