Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a lighting device for an elevator car, and particularly to a lighting device for an elevator car that can be used with a high ceiling. Regarding equipment.

(Prior Art) Elevators have become indispensable as a means of transportation up and down buildings and the like. Since this elevator has the function of transporting passengers and the like to the destination floor in a short time, it also has the function of providing a living space for the passengers, so the inside of the elevator car needs to be a comfortable space. Therefore, in modern elevators, consideration has been given to the design of lighting devices, doors, operation panels, and other accessory parts.

Even in elevators that have this purpose, the basic point is to maximize the use of the regulated size cars, but in conventional elevators, the lighting equipment attached to the ceiling occupies a large space. The ceiling was lowered and the usable capacity of the basket was reduced. This conventional elevator will be explained with reference to FIG.

The elevator car 10 installed in a building etc.
It is supported by a car support member 11 via vibration isolating rubber 12.

This car support member 11 is constructed by providing vertical frames 14, 14 (only the left one is shown in the illustrated example) on upper and lower beams 13a, 13b, and attaching braces (not shown) to these. A substantially rectangular floor support frame 16 having a side wall 15 is placed on this car support member 11.

A plurality of anti-vibration rubbers 12 are arranged at appropriate intervals above the floor support frame 16 of the car support member 11, and the elevator car 10 is placed on the anti-vibration rubbers 12. The elevator car 10 has a square-shaped floor 17
side slopes 19a, 19b, which have reinforcing plates 18a, 18b;
19c and 19d (19 and 19d are not shown) are attached, and a ceiling plate 20 is provided on the side slope 19a and the like. A door 21 is provided on the front slope 19a of the basket 10.

Further, the ceiling plate 20 includes support stands 22a, 22b and 22
The fluorescent lamp 23 is attached via c, and the fluorescent lamp 23
There is an acrylic lighting cover 24 that diffuses the light.
is attached so as to be covered with a support metal fitting 25, a support frame 26, etc.

In addition, although not shown in the drawings, this ceiling plate 18 is provided with a rescue gate for rescuing passengers, etc.

(Problem to be Solved by the Invention) By the way, the distance between the floor and the ceiling board of such a cage is usually set at a height of 2300 to 2500 mm, and there is no illumination such as a fluorescent light on the ceiling board inside this cage. The device is installed.

However, in the lighting device, at least 100 feet are required from the support stand to the fluorescent light, and the lighting cover that covers the support stand, fluorescent light, etc. must be hung down about 200 feet from the ceiling board. As a result, the effective height of the basket is reduced by approximately 10%2.
The ceiling height is lowered to 100 to 2,300 mm, which not only prevents the car from being used effectively, but also creates a feeling of pressure for passengers due to the low ceiling.

Considering the above circumstances, it is also possible to make the ceiling of the basket higher. However, when the ceiling is raised, the dimensions of the elevator hoistway at the top of the building are restricted, and the space above the ceiling when repairing or inspecting the elevator shaft is reduced, which reduces the safety of workers. There are problems such as damage.

In addition, since the fluorescent lamps are arranged at intervals on the ceiling board, the light from the fluorescent lamps becomes uneven, causing discomfort to the user.

In order to solve the above-mentioned problem, the present invention provides an elevator car lighting device that does not reduce the height of the elevator car.

[Structure of the invention]

(Means for Solving the Problems) The present invention provides an elevator car, a flat transparent panel provided on the ceiling of the elevator car and having a reflective film attached to the back surface thereof, and The elevator car is equipped with a light source that projects light from the side end face and illuminates the interior of the elevator car through the translucent panel.

(Function) Light is emitted from one end face of a flat translucent panel, and the emitted light is diffusely reflected by a reflective film. The interior of the basket is evenly illuminated by the diffusely reflected light through the translucent panel. In this way, the lighting device can be made thinner and the ceiling of the basket can be made higher.

(Embodiment) An embodiment of the lighting device for an elevator car of the present invention will be described below with reference to the drawings.

In the drawings, parts that are the same as those of the elevator car lighting system in FIG. 7 are designated by the same reference numerals, and detailed explanation thereof will be omitted.
