Description

[Detailed Description of the Invention] The present invention relates to a lighting fixture that is suspended by a chain and has a decorative tube provided with a decorative tube.

Conventionally, as shown in FIG. 7, the structure of a hanging fixture for a lighting fixture that is hung by a chain of this type is that the lower end of a pipe 9 is threaded 10, and the pipe 9 is attached to the lighting fixture body 2 with a nut 11.
fix it with
3, and the lower end of the chain 1 is interlinked with this pin 13, which has the problem of increasing the number of parts and the number of assembly steps.

Therefore, conventionally, as described in Japanese Utility Model Publication No. 43-17109 and Japanese Utility Model Publication No. 34-7984, both lower ends of an inverted V-shaped hanging bracket are fixed to the upper surface of the lighting fixture body which is suspended by a chain. , a lighting fixture has been developed in which the lower end of the chain for hanging the lighting fixture is interlinked with the center of the upper end of the hanging metal fitting, but such lighting equipment has an inverted V-shaped hanging metal fitting. There has been a problem in that the lighting equipment has an unsightly appearance because it is visible from diagonally below the lighting fixture body.

In addition, if a decorative tube is provided to hide the inverted V-shaped hanging fitting from below, it is necessary to fix the decorative tube to the top surface of the lighting equipment body using screws or other means. , there was a problem that the number of assembly steps increased.

The present invention was made in order to eliminate these drawbacks of the conventional example, and the inverted V-shaped hanging metal fittings are hidden by the decorative tube, and the decorative tube can be positioned using the hanging metal fittings. The object of the present invention is to provide a lighting fixture having a decorative tube.

The configuration of the present invention will be described below with reference to illustrated embodiments.

In FIG. 1, 1 is a chain for suspending the lighting fixture body 2, and the lower end of this chain 1 is connected to an inverted V-shaped hanging metal fitting 3.
It is interlinked with the center of the upper end.

The inverted V-shaped hanging fitting 3 has an approximately V shape with the belt-shaped plate as the border at the center.
It is formed by bending it into a letter shape, and both lower ends are folded back in the water direction as shown in Figure 2.
It is fixed to the upper surface of the lighting fixture main body 2 by a screw body 4.

Therefore, if the hanging fitting 3 is fixed with screws with the central upper end of the hanging fitting 3 interlinked with the lower end of the chain 1, assembly can be carried out extremely easily.

At the center of the upper end of the inverted V-shaped hanging fitting 3, a curved rib 5 is formed to protrude downward along the longitudinal direction of the band-shaped plate constituting the hanging fitting 3. As shown in FIG. 3, the chain rings of the chain 1 are interlinked, and a button is attached to the interlinking abutting portion A to constitute a rotatable shaft.

By providing the rotatable shaft in this manner, the lighting fixture main body 2 can be suspended in the correct posture, and its movement during rocking can be made smooth.

Furthermore, by forming the curved ribs 5, the strength of the hanging fitting 3 as a whole can be increased.

Next, FIG. 4 shows a state in which the inverted V-shaped hanging fitting 3 is covered with a decorative tube 6 to hide it, and the inverted V-shaped hanging fitting 3 as shown in FIG. The beauty of the lighting equipment as a whole is clearly improved compared to when it is exposed to light.

As shown in FIG. 5, the decorative tube 6 is taller than the inverted V-shaped hanging fitting 3, and has a volume sufficient to accommodate the entire hanging fitting 3. .

Therefore, if the decorative tube 6 is placed on the upper surface of the lighting fixture main body 2, the inverted V-shaped hanging fitting 3 will be completely invisible from diagonally below the lighting fixture main body 2.

An annular protrusion T is formed from the inner peripheral surface of the decorative tube 6 toward the center.
is formed in a protruding manner, and the inner peripheral edge of this annular protrusion γ abuts both hanging pieces of the hanging fitting 30, so that the decorative tube 6 can be positioned by the hanging fitting 3.

In this way, the decorative tube 6 has the effect of hiding the inverted V-shaped hanging fitting 30, and conversely, the inverted V-shaped hanging fitting 3 has the function of positioning the decorative tube 6. The decorative tube 6 can be fixed simply by placing the decorative tube 6 on the upper surface of the lighting fixture main body 2, and no special means for screwing the decorative tube 6 is required.

As shown in FIG. 6, a flange 8 is formed projecting from the lower end of the decorative tube 6, so that the decorative tube 6 can be supported more stably.

The present invention is constructed as described above, with both lower ends of the inverted V-shaped hanging bracket fixed to the top surface of the lighting fixture body, and a hanging chain attached to the center of the upper end of the hanging bracket. In the lighting fixtures that are interlocked, the lighting fixture body includes a decorative tube that is taller than the inverted V-shaped hanging bracket and encloses the hanging bracket so that it cannot be seen from diagonally below the lighting fixture body. Suspend the decorative tube by placing it on the top surface and bringing the inner circumferential edge of the annular protrusion that protrudes from the inner circumferential surface of the decorative tube toward the center into contact with the bottom piece of the hanging metal fitting. Since it is positioned using a metal fitting, the inverted V-shaped hanging fitting can be hidden by the decorative tube, and on the other hand, the decorative tube can be positioned using the inverted V-shaped hanging fitting. Therefore, the decorative tube can be stably fixed simply by placing it on the top surface of the lighting equipment body, and there is no need to screw the decorative tube. It is not necessary to attach mounting devices such as mounting screws or engagement holes to the decorative tube, and it has the advantage that a decorative-oriented design is possible and the number of assembly steps can be reduced.
