(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 3 shows the overall appearance of an embodiment of the elevator apparatus according to the present invention. A dispersed liquid crystal glass apparatus 3 is provided on each floor outer wall 2, 2,... An elevator car 4 moves up and down in the road 1.

As shown in FIG. 4, each of the glass portions 31 to 34 of the dispersion type liquid crystal glass device 3 has a transparent conductive film 6, 6 adhered to the inside of each of the inner and outer glass bodies 5, 5, and both of these transparent conductive films 6, , 6
It has a structure in which a capsule 8 in which liquid crystal molecules 7 are enclosed is filled.

Therefore, when no voltage is applied between the inner and outer transparent electric films 6 and 6 as shown in FIG. 3A, the liquid crystal molecules 7 in each capsule 8 are irregularly dispersed, and The incident light beam 9 becomes irregularly reflected by each capsule 8 and becomes opaque as a whole. However, as shown in FIG. 3B, if a voltage is applied between the inner and outer transparent conductive films 6, 6, the electric field generated between the transparent conductive films 6, 6 causes the liquid crystal molecules 7 in each capsule 8 to move in the direction of the electric field. , So that the light rays 9 from the outside can pass through each capsule 8 and become transparent as a whole.

Such a dispersion type liquid crystal glass device 3 is provided on the outer wall portions 2, 2,... Of all floors of the hoistway 1, and application of voltage to each glass portion 31 to 34 of the dispersion type liquid crystal glass device 3 is performed. ,
The circuit configuration for controlling the release is as shown in FIG.

In FIG. 1, between a DC power supply PN, a door closing confirmation relay a contact 10a that is turned on when the elevator door is fully closed, an ascending direction call detection relay b contact 11b that is turned on for an elevator ascending direction call, and as for an elevator descending direction call. A falling call detection relay b contact 12b that turns on and a no-call detection timer 13 are provided in series.

A stop detection relay b contact 14b that is turned on when the elevator is stopped, an inspection detection relay b contact 15b that is turned on when the elevator is checked, and a travel detection relay a contact 16a that is turned on when the elevator is running are connected in series between the AC power sources RI. It is connected to the.

The glass portions 31 to 34 on each floor of the dispersion-type liquid crystal glass device 3 are connected to the traveling detection relay a contact 16a via diodes 17, 17,.

Each of the glass sections 31 to 34 is provided with a landing detection relay a contact 41a to 44a of each floor of the elevator in parallel with the diode 17, 17,.... The contacts 41a to 44a are the traveling detection relay a contacts 16a.
No-call detection timer relay a contact 13 provided in parallel with
Connected to a.

Further, for the traveling detection relay a contact 16a,
A relay b contact 13b is connected in parallel with the no-call detection timer relay a contact 13a, and one end of the no-call detection timer relay b contact 13b is connected to the diodes 17, 17,.
It is connected to the.

The operation of the viewing elevator apparatus having the above configuration will be described below.

As shown in the flowchart of FIG. 2, when the elevator operation switch is not turned on and the stop detection relay b contact 14b is turned off (step S1), the elevator inspection switch is turned on, and the inspection detection is performed. Relay b
When the contact 15b is off (step S2), the power supply between the AC circuits RI is cut off, and no voltage is applied to each of the glass parts 31 to 34 of the dispersion type liquid crystal glass device 3, and accordingly, each of the glass parts 31 to 34 are in the opaque state shown in FIG. 4A, and the outer wall of the entire hoistway 1 is opaque (step S3).

When the elevator is in normal operation and the elevator check switch is off, the stop detection relay b contact
14b, the inspection detection relay b contact 15b is turned on, and it is determined whether or not the elevator is traveling by turning on / off the traveling detection relay a contact 16a (step S4). In this case, AC power is supplied between the AC power sources RI, and a voltage is applied to each of the glass parts 31 to 34 of the dispersion-type liquid crystal glass device 3 via each of the diodes 17, 17,... As a result, the respective glass parts 31 to 34 become transparent as shown in FIG. 4 (b), and the entire hoistway 1 becomes transparent as shown in FIG. 3 (b) (step S5).

Also, in step S4, even when the elevator is stopped and the traveling detection relay a contact 16a is off, the no-call time has not elapsed for a certain period of time, and the no-call detection timer 13 is still If not operating, the no-call detection timer relay b contact 13b is maintained in the ON state, a voltage is applied to each of the glass portions 31 to 34 via the diodes 17, 17,..., And the entire hoistway 1 becomes transparent. (Steps S6 and S5).

However, when the elevator is stopped, the no-call detection timer 13 operates, and when a certain period of time has elapsed,
The traveling detection relay a contact 16a is turned off, the no-call detection timer relay b contact 13b is also turned off, and only the no-call detection timer relay a contact 13a is turned on. Here, if the elevator car is stopped at a certain floor, the landing detection contacts of the corresponding floor among the landing detection contacts 41a to 44a, for example, 3
Only the floor landing detection contact 43a is turned on, the other landing detection contacts 41a, 42a, and 44a are both turned off, and a voltage is applied only to the glass part 33 on the third floor by the AC power supply RI. a)
, Only the glass part 33 on the third floor becomes transparent, and the glass parts 31, 32, and 34 on the other floors of the hoistway 1 are placed in an opaque state (step S7).

In this way, when the elevator is operating normally, the entire hoistway is made transparent, and when there is no elevator call for a certain period of time, the elevator is made transparent only on the floor where the elevator stops. By making all other parts opaque, it is possible to prevent the sunlight from directly entering the hoistway, suppress the rise in the temperature of the hoistway and the elevator car, and make the entire hoistway stop. It is not exposed to the public, and at the same time, only the elevator car part is transparent, so that the design can be complemented and seen, and the design effect can be enhanced.

Further, in this embodiment, since the entire hoistway is opaque during the inspection operation, the inspection worker is not exposed to the outside during the inspection operation, and the inspection operation can be easily performed.

In the above embodiment, the transparent and opaque operation of the glass part on each floor of the dispersion type liquid crystal glass device is controlled by a sequence control operation using a relay contact. , A digital control method is also possible.

As described above, according to this embodiment, the glass part of each floor of the hoistway outer wall can be switched between transparent and opaque using a dispersion type liquid crystal glass device, and only the glass part of the elevator stop floor is used when there is no elevator call for a predetermined time or more. Because it is transparent, all glass parts on the other floors are opaque, and glass parts on all floors are transparent during elevator driving,
When the elevator is stopped at a certain floor for a long time, the sunlight does not enter the entire hoistway and does not increase the temperature rise of the hoistway and the elevator car.
The power consumption of the cooler in the elevator car due to unnecessary temperature rise can be suppressed. In addition, when the elevator is stopped for a certain period of time, the glass on the floor other than the stop floor is made opaque, and only the glass on the stop floor is made transparent. Can be raised and the advertising effect can be enhanced.

[Effects of the Invention] As described above, according to the present invention, the glass part of the outer wall of the hoistway of an elevator is made transparent only when necessary, and when it is unnecessary, it is made opaque by a shielding device to reduce the amount of sunlight into the hoistway. It is possible to restrict and to block the line of sight from both inside and outside the basket.
