Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an elevator cab lighting system.

Figure 1 shows an example of a conventional elevator cab lighting system. In Figure 1, (1) the foot and floor, (2)
(2) is a side wall erected at the end of this car floor and surrounds it on three sides, (3) is a ceiling 1 fixed to the upper end of this side wall (21 to (2)) (3a) is a side wall erected at the end of this car floor (1). ), side wall (2) ~
The car room surrounded by (2) and the ceiling +31, (4) is fixed to the ceiling (31 and hangs down, the lower part is bent to the opposite wall (21@), and the longitudinal section is formed in a 5-shape, @ wall 121
Along K [A frame body that is set up and forms a 9-piece shape.

(&) is a cross-shaped partition fixed to the four sides of this frame (4), and (5) is a mirror-finished partition with multiple through holes for transmitting light to illuminate the car compartment (k). This is a light shield made of a stainless steel plate, and is supported by the frame (4) and partition (4a) K with the mirror surface facing the car compartment (k). (6) to (6) are light guides made of a transparent material that are inserted into the through holes of the light shield (5) and illuminate the car compartment (k).

In the elevator car lighting system configured as described above, the lower surface of the light shield (51) is uneven and has a three-dimensional effect 2, and the light shield (51) has a mirror finish, so it reflects 9 reflections. This improves the lighting effect.

However, since the light shielding body (5) was made of a stainless steel plate, it was large in quantity. As a result, the weight of the car increases, and the counterweight connected to the car with a rope to counteract the weight of the car also becomes heavy, resulting in an increase in the energy required to accelerate the elevator. .

This invention has been made in view of the above-mentioned disadvantages, and provides a cab lighting device including a light shielding body provided below the light source and having a light-transmitting portion for illuminating the cab.
The weight of the light shielding body was reduced by constructing the light shielding body with a composite plate consisting of a synthetic resin plate and a thin metal plate with a mirror surface fixed to the lower surface of the synthetic resin plate.

The purpose of this is to reduce the energy required for acceleration.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In (5), a plurality of through holes (5a) are formed to transmit light in order to illuminate the car compartment (k). , and has a bent part (5C) bent upward at a right angle through a groove (5b) formed in one peripheral part, and a frame (4).
)K supported. (5d) is the light shielding body (5
) is a synthetic resin board made of polyester that forms the base of the
(5θ) is a metal plate fixed to the upper surface of this synthetic resin plate (5d); an upper aluminum plate e (Sf) is a lower aluminum plate, which is also a metal plate fixed to the entire lower surface.

(5g) is the lower aluminum plate (5f), a mirror surface made of K-plated chrome, (7) is a light source made of a fluorescent lamp, and (8) is a light shield placed on the top of the light guide (6). This is a holding plate made of a transparent material that holds the light guide (6) together with (5).

In the elevator car lighting system having the above configuration, the light shielding body (5) has a mirror surface portion (5 g
), it has the same reflective lighting effect as the conventional stainless steel plate, and the base is made of synthetic resin (5d), so it is different from the conventional stainless steel plate. It is lighter in comparison. Furthermore, since the bent portion (Sc) is provided at the peripheral portion, it has sufficient strength required for the 9 functions.

In the above embodiment, the synthetic resin constituting the light shielding body (5) was made of polyester, but flexible materials such as vinyl chloride and polycarbonate may be used as well, with bending at the periphery as in the above embodiment. (5C) can be provided.

In addition, in the above embodiment, the light shielding plate (
5) In order to prevent distortion, the upper aluminum plate (5e) was fixed to the upper surface of the 9 synthetic resin plate (5d), and the lower aluminum plate (5f) was fixed to the lower surface, but only the lower aluminum plate (5f) was fixed. It is clear that the above embodiment also functions similarly.

FIG. 4 shows another embodiment of the present invention, and in FIG. 1, (5) is an upper aluminum plate in which a plurality of circular notched holes are formed in a synthetic resin plate (5d) made of a transparent material. (5e) and a lower aluminum plate (5f) in which a notch hole is formed in a portion opposite to the notch hole (Sa) of this upper aluminum plate (5e), and furthermore, a chrome plate is attached to this lower aluminum plate (5e). Plated mirror surface (5

d) A light guide adhered to the lower surface of the light guide. Kll like this
The elevator cab illumination device thus constructed is also lightweight, similar to the embodiments shown in FIGS. 2 and 3.

As described above, the present invention provides a car interior lighting device including a light shielding body that is provided below a light source disposed in an upper part of the car compartment and illuminates the car compartment by passing the light from the light source. The base of the light shielding body is made of a synthetic resin plate, and the lower surface of the synthetic resin plate has a through hole through which the light from the light source is transmitted.

By attaching a metal plate with a mirror surface, the weight of the light shield can be reduced.

This has the effect of reducing the energy required by the elevator during acceleration.
