Description

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

FIG. 1 shows an example of a conventional elevator car lighting system, and in the figure, 1 is a car floor, 2 to 2 are side walls that are erected at the ends of this car floor 1 and surround it on three sides, and 3 is a ceiling fixed to the upper end of these side walls 2-2, 3a is a car room surrounded by the above-mentioned car floor 1, side walls 2-2 and ceiling 3, 4 is fixed to the ceiling 3 and hangs down, and the lower part is the opposite wall. bent to the 2nd side,
A frame body having an L-shape in longitudinal section and provided along the side wall 2 to form a square shape; 4a is a cross-shaped partition fixed to the four sides of the frame body 4; 5 is a car compartment 3;
It is a light shielding body made of a mirror-finished stainless steel plate in which a plurality of through holes are formed for transmitting light in order to illuminate the car compartment 3a, and it is supported by the frame 4 and the partition 4a with the mirror surface facing the car compartment 3a side. It is something.
Reference numerals 6 to 6 denote light guides made of a transparent material that are inserted into the through holes of the light shielding body 5 and illuminate the car compartment 3a.

In the elevator cab illumination device configured as described above, the lower surface of the light shield 5 is uneven, giving a three-dimensional effect, and the light shield 5 is mirror-finished, so the illumination is caused by reflection. The effect is improved.

However, since the light shielding body 5 was made of a stainless steel plate, it was heavy. For this reason,
There was a problem in that the weight of the car increased, and the counterweight connected to the car with a rope to counteract the weight of the car also became heavy, increasing the energy required to accelerate the elevator.

This invention has been made in view of the above-mentioned disadvantages, and provides a car interior lighting device equipped with a light shield provided below the light source and having a light-transmitting part for illuminating the car. The weight of the light shielding body is reduced by constructing it 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, thereby reducing the weight required for acceleration. The purpose is to reduce energy.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. Reference numeral 5 has a plurality of through holes 5a through which light passes through in order to illuminate the car compartment 3a, and the periphery of the cage 3a is This is a light shielding body having a bent portion 5c bent upward at a right angle through a groove 5b formed therein, and is supported by the frame 4. 5d is a synthetic resin plate made of polyester that constitutes the base of the light shielding body 5; 5e is an upper aluminum plate which is a metal plate fixed to the upper surface of the synthetic resin plate 5d;
5f is a lower aluminum plate which is also a metal plate fixed to the entire lower surface, 5g is a mirror surface made of chrome plated on this lower aluminum plate 5f,
7 is a light source made of a fluorescent lamp, and 8 is a holding plate made of a transparent material that is placed above the light guide 6 and holds the light guide 6 together with the light shield 5.

In the elevator cab illumination device having the above configuration, the light shielding body 5 is constituted by a mirror surface portion 5g whose lower surface is plated with chrome, so that it has a lighting effect by reflection similar to a conventional stainless steel plate, and Since the base is made of synthetic resin 5d, it is lighter than the conventional one made of stainless steel plate. Furthermore, since the bent portion 5c is provided at the peripheral portion, it has sufficient strength required for functionality.

In addition, in the above embodiment, the synthetic resin constituting the light shielding body 5 was made of polyester.
Even if a flexible material such as vinyl chloride material or polycarbonate is used, the bent portion 5c can be provided at the peripheral portion as in the above embodiment.

FIG. 4 shows another embodiment of the present invention, and in the figure, reference numeral 5 denotes an upper aluminum plate 5e in which a plurality of circular notched holes are formed in a synthetic resin plate 5d made of a transparent material; A light shielding body in which a lower aluminum plate 5f having a notch hole formed in a portion opposite to the notch hole 5a of the upper aluminum plate 5e is fixed to the lower aluminum plate 5e, and a mirror surface portion 5g plated with chrome is further formed on the lower aluminum plate; Reference numeral 6 denotes a light guide that passes through the cutout hole of the lower aluminum plate 5f and is adhered to the lower surface of the synthetic resin plate 5d. The elevator cab illumination device constructed in this manner is also lightweight, similar to the embodiments shown in FIGS. 2 and 3.

As described above, the present invention includes a light shielding body made of a synthetic resin plate with metal plates attached to both sides and a mirror surface of the lower metal plate, which is disposed directly below the light source in the upper part of the car compartment. This invention relates to a car lighting device in which a light guide is passed through the light guide so that its lower end hangs down below the lower surface of the light shield.

Since the light shielding body has a synthetic resin base instead of metal, it is lighter, making it possible to reduce the weight of the entire basket, and since it has high rigidity, it does not deform due to heat.

Additionally, it is stipulated that the gap between the car and the top of the hoistway when the car stops at the top floor must be set to a predetermined value or more in accordance with the car speed (Article 129-6 of the Building Standards Act Enforcement Ordinance). (paragraph 1, item 5). For this reason, there is a desire to lower the car in order to lower the total height of the hoistway and reduce construction costs, and the hanging dimension of the light guide is also limited. , so the drooping dimension is 2
It appears to double in size, gives a sense of depth even if the hanging dimension is small, and can be used as an attractive-looking cage lighting.
