Abstract

PURPOSE: To make a light shadeable in time of disuse by using instantaneous dimming liquid crystal glass for a windowpane of a car gondola, while controlling a current energization to an electrode of this liquid crystal glass, and varying the windowpane into being turbid enough according to a passing part of the car gondola. CONSTITUTION: Instantaneous dimming liquid crystal glass 4 being made up of being stacked in a sandwich by a pair of transparent electrodes in an interval between two sheets of transparent glass is stuck to a partial or full wall surface of the car gondola 3, while a switch energizing a current to the electrode is installed, through which shading takes place in time of energization but light transmission takes place in time of being unenergizd. This switch is controllable by automatic or manual operation, and when it passes through by an office adjacent to an elevator shaft 1, a light is shaded, making the inside unseen, and further if there is an acrophobian passenger, the light is also shaded for protection's sake. With this constitution, a windowpane is easily varied for shading or transmitting, making it conformable to passenger services.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a see-through type elevator in which a part or whole of a wall surface is covered with glass so that an external scenery can be seen.

[0002]

2. Description of the Related Art Recently, in a hotel, a commercial building, etc., part or all of the wall surface of an elevator gondola is covered with glass for the purpose of design, and the outside surface of the elevator shaft is covered with glass so that the outside can be seen. So-called see-through type elevators, which have made it possible to enjoy, have become popular.

[0003]

However, with such a structure, when the elevator shaft is close to the office space inside the atrium, the inside of the office space can be seen from the gondola, while the gondola on the other hand is visible. When enters the underground part, the wall surface inside the shaft can be seen from inside the gondola, which may be inconvenient. On the other hand, on the other hand, on the approach floor, there are cases where you do not want to see the inside of the gondola from the outside.

By the way, there is an instantaneous light control type liquid crystal glass as a means for arbitrarily adjusting the light shielding and the through hole. In this case, the glass becomes opaque when the electrodes are energized and becomes transparent when the energization is cut off.

The present invention has been made on the basis of the above-mentioned viewpoints, and its object is to provide a window in a part of a see-through type elevator where the outside of the gondola is not desired to be seen or the outside of the gondola is not desired to be seen. Provides a see-through type elevator that can make a lath instantaneously opaque.

[0006]

In order to achieve the above object, the present invention uses an instantaneous light control type liquid crystal glass for a window glass of a gondola, and energizes an electrode of the liquid crystal glass to a passage portion of the gondola. ON or OFF according to
It is characterized in that it is provided with a switch means for switching.

[0007]

[Operation] For example, at the time when the gondola passes through a part that you do not want to see the outside from the inside of the gondola or a part that you do not want to see the inside of the gondola, such as the office space near the elevator shaft or the inner wall surface of the shaft in the underground part, When the electrodes are energized through the switch means, the glass becomes opaque and shields the inside and outside of the gondola.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a see-through type elevator according to the present invention. Basement B of the building in the figure
Except for F, the surface of the shaft tunnel 1 facing the outside is covered with the transparent glass 2.

Further, the entire wall surface of the gondola 3 which moves up and down in the shaft tunnel 1 and which faces the outside is constituted by an instant light control liquid crystal glass 4.

As shown in FIG. 2, the instant light control liquid crystal glass 4 has a pair of transparent electrodes 4b between two transparent glasses 4a.
It is a sandwich of liquid crystals 4c separated by
When the power source 5 connected to the electrode 4b is in the non-energized state, it is transparent like ordinary transparent glass, and when the electrode 4b is energized from this state, it becomes opaque and shields light.

The energizing switch 6 is the gondola 3
Turns on in conjunction with a detection means (not shown) when passing through the basement floor BF and the approach floor 1F, and turns off on the upper floors.

As a result, as shown in FIG. 3 (a), the glass 4 becomes opaque when passing through the basement floor BF and the first floor, and the inside and outside of the gondola 3 are visually blocked.

Further, when passing the upper floor, the glass 4 becomes transparent as shown in FIG. 3 (b), and the inside and outside of the gondola 3 are visually communicated with each other, so that the person inside the gondola 4 can see the outside scenery. You will be able to enjoy it.

In addition to the above configuration, by manually turning on and off the liquid crystal glass 4 by a manual operation inside the gondola 3, it is possible to deal with, for example, a passenger with a fear of heights.

[0015]

As described above in detail with reference to the embodiments, in the see-through type elevator according to the present invention, for example, in the gondola such as the office space adjacent to the elevator shaft or the shaft inner wall surface in the underground part. When the gondola passes through the part where you do not want to see the outside from the outside or the part where you do not want to see the inside of the gondola from the outside, when the electrodes are energized through the switch means, the glass changes to opaque and shields the inside and outside of the gondola. In addition to being able to reduce the restrictions of the above, there is an advantage that it can be applied to passenger service.

Further, the intermittentness of the scenery can give the elevator itself unexpectedness and entertainment.
