Abstract

PURPOSE:To improve a design effect while easily shielding the inside of a cage by carrying a current in liquid crystal glass, applied to a glass window, to blur it in an obscured glass shape, at the time of specific operation of an elevator whose cage inside is prevented from being seen from the outside. CONSTITUTION:In order to normally enjoy observation of the outside from a cage of an observation elevator, current carrying is not performed in upper/ lower part window glasses (liquid crystal glass) 2, 3 of the cage, to perform operation in a condition of transparent glass. On the other hand, for instance, in a certain time band, a changeover switch stored in a control panel or the like in the cage is turned on to excite an auxiliary relay, and RB1, RB2, which are contacts of this relay, are energized, so that a current is carried in the lower part window glass 3 of the cage corresponding to height from a foot to a waist part of a person, to blur this glass in an obscured glass shape, that is, to perform repatterning a cage design. By turning on the other changeover switch, similarly a current is carried in the upper part window glass 2 to blur it, and a cage inside is placed in a shielded condition.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass window in a car room of a view elevator, and more particularly to a view elevator installed in buildings such as department stores, supermarkets, office buildings, various towers, and government office buildings.

[0002]

2. Description of the Prior Art In conventional elevators for prospects, as a means for shielding from the outside, as described in Japanese Utility Model Publication No. 57-3780, when a car arrives at a specific floor, the glass window is blocked by the operation of a position detector. A view elevator with shielding means was filed.

In the present invention, the elevator for observation is a normal view where the outside view can be enjoyed from the transparent glass window. However, when a specific operation is performed, liquid crystal glass is used to energize the glass window of the cab so that the entire glass window is opened. By partially or partially frosting the glass so that the inside of the car cannot be seen even when the elevator is operating, or by making one part of the glass window transparent and the other part frosted glass It is possible to improve the design effect of.

[0004]

The above-mentioned prior art relates to a window glass for a car of a prospective elevator. In Japanese Utility Model Laid-Open No. 57780/1982, the window is blocked after the arrival of the elevator is detected by a position detecting device. It was to apply the shielding means.

The object of the present invention is that the outside can be seen from the transparent glass window in the normal operation, and if the inside of the elevator car cannot be seen from the outside, it is shielded.
Or, depending on the time of day, the glass window of the cab may be made of transparent glass that allows the outside to be enjoyed, and at some time the glass window may be made entirely frosted glass to enhance the design effect of the elevator for observation.

[0006]

[Means for Solving the Problems] To achieve the above object, as shown in Japanese Utility Model Application Laid-Open No. 57-3780, a car room may be equipped with a shielding means for blocking a glass window. It looks bad in terms of design. The mechanism of the elevator for observation is that the window glass itself is transparent glass, and if the transparent glass changes to frosted glass by energization, the design effect as a elevator for observation is great.

[0007]

[Function] In a normal elevator for observation, it is a car room and a hoistway that are configured so that the outside can be viewed from a transparent glass window. However, when the elevator is operated in a specific way, the car room cannot be seen from the outside, Has a design effect of the cab as an outlook elevator by making the whole or a part of the glazing transparent frosted glass into frosted glass.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The present invention is intended for a prospective elevator installed in buildings such as department stores, supermarkets, office buildings, various towers, and government office buildings.

FIG. 1 is a perspective view of a car of an elevator for observation according to the present invention. The car 1 of the elevator for observation has an upper window glass (liquid crystal glass) of a car room in a window frame portion to enable external observation. 2 Equipped with lower window glass (liquid crystal glass) 3 of the car room, and a car 1 of the elevator for observation
An operation panel that controls the elevators is installed on the side of the entrance door.

Normally, in order to enjoy the outside view from the elevator car 1 for viewing the elevator, the elevator is operated with the upper and lower window glasses 2 and 3 of the car room being transparent glass. Also, at a certain time, for example, by changing the lower window glass (liquid crystal glass) 3 of the cab, which corresponds to the height of a person's feet to the waist, to a frosted glass, the design of the car can be changed even during normal operation. It is possible to enhance the function as a view elevator.

A pattern changing method in this case will be described with reference to FIGS. Changeover switch (SW) stored in the switch box of the operation panel installed in the car room
B) 4 is energized is RB ₁ and RB ₂ and the auxiliary relay RB5 to turn are excited by and contacts b and is energized in the lower window glass (crystal glass) 3 cab, those were transparent glass It changes to frosted glass and the pattern on the window glass changes. If you do not want to see the car interior from the outside, turning on the switch SWA further energizes the upper window glass 2 of the car room like the changeover switch SWB and changes to frosted glass. Will be an elevator for observation with a frosted glass appearance.

When the outside view is to be enjoyed from the cab, SWA of the changeover switch 4 is turned off or SW
Turn off both A and SWB.

By changing over these switches 4, the window glass of the cab can be changed from transparent to frosted glass so that the design of the elevator for observation can be improved.

EFFECTS OF THE INVENTION According to the present invention, in a car room or hoistway constructed so that the outside can be seen from a transparent glass window, electricity is supplied to the entire surface of the window glass when it is not desired to see the car room from the outside. The entire glass becomes frosted glass, and a part of the window glass is made transparent, while the other part is made frosted glass, so that the design effect as a prospective elevator can be improved.
