Description

[Detailed Description of the Invention] The present invention relates to a shade for lighting equipment in which an upper shade body and a lower shade body are locked and fixed into one body, and a decorative band is attached to the end face of the shade.

In recent years, decorative bands have come to be used frequently in shades for lighting equipment in order to improve their decorative effects.

The decorative band is usually made of rubber or a synthetic resin material such as vinyl chloride and has a U-shaped cross section.

When the upper shade body and the lower shade body were to be fitted together, the flanges on the end faces of both shade bodies were brought together, a decorative band was fitted into the palm joining part, and the palm joining parts were clamped and connected by the band.

In addition, in some cases, the palm-contacting portions of the end faces of the upper and lower shade bodies are locked together or fixed with screws, and a decorative band is attached thereon.

By the way, this shade requires disassembling the upper and lower shade bodies and cleaning the inside from time to time in order to remove dirt and the like that occur over the course of use, and it is important for sales to have a shade that has a structure that makes this troublesome cleaning easy. There were two points.

However, in the conventional shade with a decorative band (for example, Utility Model Application No. 54-60643; Publication of Utility Model Publication No. 58-48728), the decorative band is attached to the shade which has an upper shade body and a lower shade body as one body as described above. Therefore, when disassembling for cleaning etc., first the band is removed and then the upper and lower shade bodies are separated, which is not only time-consuming and troublesome but also difficult to assemble the shade after cleaning. It was troublesome and not very good in terms of sales.

In view of these drawbacks, the present invention improves and eliminates them, and provides a shade for a lighting fixture that allows the upper and lower shade bodies to be separated without removing the decorative band and facilitates disassembly and assembly. The purpose is to

Hereinafter, the configuration of the present invention will be explained based on the embodiments shown in the drawings.

FIG. 1 shows an embodiment of a shade A for lighting equipment according to the present invention.

1 is an upper shade body, 2 is a lower shade body fitted and fixed to the upper shade body 1, and 3 is a decorative band fitted to the end face of the lower shade body 2, which is made of rubber material or synthetic resin material as in the past. It is made to be flexible and stretchable.

As shown in FIG. 2, the upper shade body 1 has an angular notch 5 in the end flange 4 of the circular lower opening, and a protruding first stopper on the flange at an appropriate distance from the notch 5. 6 is formed, and a protruding second stopper 6' is further formed at an interval slightly longer than the width of the notch 5.

The first stopper 6 may be at the same height as the second stopper 6', but it is usually formed slightly lower.

A plurality of sets of such notches and stoppers are arranged on the flange 4 at equal intervals.

Further, as shown in FIG. 3, the lower shade body 2 has an end face flange 7 of the circular upper opening formed in a cross-sectional shape, and extends from the upper edge of the L-shaped flange 7 in correspondence with the notch 5 of the upper shade body 1. It is bent inward to provide a protruding locking piece 8.

The locking piece 8 is a rectangular plate large enough to fit into the notch 5 and pass through it.

Further, the horizontal plate 7a of the L-shaped flange 7 has a width on which the flange 4 of the upper shade body 1 rests, and the vertical plate 7b is between the horizontal plate 7a forming the U-shape and the protruding locking piece 8. It is formed to have a rising length that allows the flange 4 of the upper shade body 1 to be fitted almost tightly.

What is shown in FIG. 4 is an annular decorative band 3, which is formed into a U-shaped cross section with a concave inner surface as shown in the figure, and has a concave recess that fits into the L-shaped flange 7 of the lower shade body 2. Let's take the shape.

In this case, the width of the U-shaped lower plate 3' of the band 3 is such that it is in close contact with the lower surface of the horizontal plate 7a of the flange 7 of the lower shade body 2 over its entire width, but the upper plate 3'' is The width should be such that it locks onto the upper edge 7c.

That is, the inner diameter of the upper plate of the band 3 is adjusted to the outer diameter of the flange of the lower shade body 2.

Next, the procedure for assembling the above structure will be explained.

As shown in FIG. 6, the decorative band 3 is fitted onto the lower shade body 2, although the upper and lower shade bodies may be assembled either at the front or rear.

The upper part of the band 3 is only locked to the upper edge 7c of the flange 7, and the locking piece 8 remains in its protruding state.

The upper and lower shade bodies 1 and 2 are assembled as follows.

As shown in FIG. 5, the locking piece 8 of the lower shade body 2 is inserted from below into the notch 5 of the flange 4 of the upper shade body 1 so as to protrude from the flange 4, and the flange 4 and the lower shade body flange are connected to each other. 7 horizontally dividing plate 7a.

Then, when the lower shade body 2 is turned to the right in the drawing, the locking piece 8
passes over the first stopper 6 and enters between the stopper 6 and the second stopper 6' as shown.

Since the first stopper 6 slightly protrudes from the flange plate surface, the locking piece 8 can easily and smoothly get over the first stopper 6, and once it enters between the two stoppers 6, 6', the lower shade Due to the weight of the body 2, the locking piece 8 is moved to the first position.
Since it is pressed against the flange 4 between the second stoppers 6 and 6', it cannot be easily pulled out.

In this way, even when the lower shade body 2 is attached with the decorative band 3, the upper plate 3'' of the band 3 does not overlap the locking piece 8, so that the lower shade body 2 can be easily integrated with the upper shade 1 as shown in FIG. When assembled and hung, the lower shade body 2 is stably attached without accidentally shifting due to its own weight and the engagement of the locking piece 8 to the flange 4 of the upper shade body 1. It becomes A.

In addition, in the present invention, the shade can be configured not only in a round shape but also in a square shape, and the waist band can also be changed to match the shape of the shade.

As described above, according to the present invention, the upper shade body and the lower shade body can be freely attached and detached while the band is fitted into the lower shade body.

Moreover, since the band is given flexibility, it will not come off accidentally from the lower shade body.

Moreover, the band exhibits an excellent decorative effect and enhances the marketability of the lighting equipment.
