Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a lighting device for illuminating an elevator cab.

The elevator cab is equipped with lighting lights and a suspended ceiling to house them. This is shown in FIGS. 1 and 2.

In the figure, 1 is a car room, 2 is a car floor forming the lower part of car room 1, 3 is a canopy forming the upper part, and 4
is a box-shaped suspended ceiling attached to the canopy 3; 4a is a window hole opening at the bottom of the suspended ceiling 4; 5 is a lighting plate that closes the window hole 4a of the suspended ceiling 4; 6 is a box-shaped suspended ceiling attached to the canopy 3; Illumination lights 7 are housed in the suspended ceiling 4, and are side walls forming the four circumferences of the cage 1.

The interior of the car room 1 is illuminated by the lighting device configured as described above.

However, as is clear from the figure, the appearance of the ceiling of the car room 1 is fixed, and the appearance of the ceiling of the car room 1 together with the side wall 7 is fixed.
are kept in closed rooms, making it easy for passengers to feel uneasy.

The present invention is intended to improve the above-mentioned problems, and an object of the present invention is to provide a lighting device for an elevator car that can alleviate passengers' sense of anxiety due to the car being a closed room.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

In the figure, reference numeral 5 denotes an illumination plate disposed below the illumination lamp 6 and formed of a translucent milky white synthetic resin plate, etc.;
5X is a shaft whose one end is fixed to the back surface of the lighting plate 5 and extends upward, and 8 is a drive device such as an electric motor that is attached to the canopy 3 and drives the shaft 5X while changing the speed according to the elevator speed of the car. .

The drive device 8 rotates the illumination plate 5 in each direction of the arrow in FIG. 4 via the shaft 5X at an appropriate speed.
As a result, the appearance of the ceiling of the car room 1 changes from time to time, and unlike conventional fixed ceilings, the appearance of the ceiling is extremely varied, providing enjoyment to passengers. Therefore, the feeling of being in a closed room is alleviated, and passengers' feelings of anxiety are eliminated.

Since the rotation of the illumination plate 5 changes according to the elevator car's speed, it displays a sense of speed to the passengers.
It can make you feel.

FIGS. 5 and 6 show other embodiments of the invention.

In the figure, 5A is a lighting plate having a light plate 5Aa formed in a disc shape and made of a translucent colored synthetic resin plate;
5B is also a lighting plate with a shape that is an inversion of the lighting plate 5A, and has a different color from the light plate 5Aa (not shown).
have.

The illumination plate 5B is rotated clockwise A in FIG. 6 by the drive device 8, and the illumination plate 5A is similarly rotated counterclockwise B. However, a detailed description of the mechanical connection between the illumination plate 5A and the drive device 8 will be omitted.

Since the illumination plates 5A and 5B rotate in opposite directions, the illumination light of the illumination lamp 6 seen through the light plate 5Aa changes, and the atmosphere in the car room 1 becomes significantly active. Also in this embodiment, since the illumination plates 5A and 5B change their rotation in accordance with the elevator speed of the car, a sense of speed can be expressed.

It goes without saying that the shapes of the illumination plates 5, 5A, and 5B in each of the above embodiments are not limited to these, and can be freely selected.

Furthermore, the illumination plates 5, 5A, and 5B may be oscillating rather than rotating, and the shaft 7 may be arranged not only vertically but also horizontally.

As explained above, in this invention, the lighting board provided below the car room lighting is made to move according to the lifting speed of the car using a driving device, so that the appearance of the car ceiling does not change. This can alleviate the feeling of being in a closed room for passengers.

Furthermore, in this invention, since the movement of the lighting board is changed according to the speed of the car, it is possible to display the sense of speed to passengers and make them feel it, further reducing the feeling of being in a closed room. It is something.
