Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an improvement in an elevator ceiling lighting lamp cover used for indirectly illuminating the interior of an elevator car by lighting provided on a ceiling panel.

[Background of the invention]

Generally, an elevator car 3 is constructed by attaching a ceiling plate 2 to the upper part of a side plate 1 as shown in FIG. A lamp 4 is attached to this ceiling plate 2, and a lamp cover 6 is attached to each of the shielding plates 5 attached to cover the lamp 4 to cover a plurality of holes formed corresponding to the lamps 4.
A ceiling lighting device is constructed in this manner. Therefore, the ceiling lighting device illuminates the interior of the elevator compartment 3 through the lamp cover 6.

In the conventional lamp cover 6, a milky white lamp cover is often used in order to softly illuminate the inside of the elevator passenger car 3. Such lamp covers result in insufficient illuminance, and recently transparent lamp covers have been desired.

However, if the lamp cover 6 is simply made transparent, the lamp 4, lighting wiring, etc. will be visible from inside the elevator seat 3, which will impair the aesthetics.

Therefore, a lamp cover 6 is used in which the upper surface of the ceiling panel 2 side shown in FIG.
Removing it becomes a very difficult task.

As a general countermeasure of this kind, as shown in FIG. 5, the lamp cover is divided into two parts in the vertical direction, and the lower surface of the upper transparent plate 8 placed on the lower transparent plate 7 is made rough to prevent the accumulation of flakes, etc. The upper surface A of the transparent plate 7 is smoothed to facilitate cleaning. However, such a structure requires bonding, riveting, etc. to join the transparent plates 7 and 8, which increases the number of steps.

On the other hand, it is conceivable to cover the plurality of transparent plates 7 with a single flat plate 9 having irregularities on the lower surface as shown in FIG. 6, but this increases the manufacturing cost.

In addition, this type of lighting device is generally used in the
It has been introduced in Japanese Utility Model Publication No. 7996 and Japanese Utility Model Application Publication No. 54-4505.

[Purpose of the invention]

An object of the present invention is to provide an elevator ceiling lighting lamp cover that improves the illuminance and design effect in an elevator car and is easy to clean.

[Summary of the invention]

The present invention is characterized in that the lamp cover is a single unit made of a transparent material, its lower surface is provided with irregularities so that the ceiling cannot be seen from inside the elevator car, and its upper surface is smooth.

[Embodiments of the invention]

Embodiments of the present invention will be explained below with reference to the drawings.

FIG. 1 is a perspective view of the lamp cover 6 seen from below;
The figure is an enlarged view.

The lamp cover 6 is constructed as a single unit made of a transparent material, and has a flange portion 6a. The upper surface A of the flange 6a facing the lamp 4 is smooth, while the lower surface B visible to passengers is provided with irregularities formed in a geometric pattern.

Since such a lamp cover 6 is integrated, it is more economically advantageous than those shown in FIG. 5 and FIG. 1g6.

In addition, since the lower surface Bk has irregularities with a geometric pattern, passengers cannot see the lamps, wiring, etc. even though the lamp cover 6 is transparent, and rather the geometric pattern PK creates a beautiful design. At the same time, sufficient illuminance can be provided from the lamp 4 into the elevator car. Also, upper surface A
Since it is smooth, it can be easily cleaned even if clumps etc. accumulate.

〔Effect of the invention〕

As explained above, in the present invention, the lower surface of the lamp cover made of a transparent body is made uneven and the upper surface is made smooth.
Sufficient illuminance can be given to the interior of the elevator car without showing the lamps and wiring to the passengers, so the design effect for the passengers is enhanced, and even if dust accumulates on the upper surface, it can be easily cleaned.
