DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 1 to 3 show an example of an embodiment of the present invention. FIG. 1 is a front view of a door for opening and closing an entrance, FIG. 2 is a plan view of FIG. 1, and FIG.
It is a front view of an operation panel of an elevator provided with a door. Except for FIGS. 1 to 3, the elevator apparatus is configured similarly to the above-described FIGS. 4 to 9. In the figure, 7 is a door composed of a sliding door for opening and closing the car doorway 4 or the landing doorway 6, 8 is a glass structure in which a sheet glass is fitted into a metal frame, 9 is provided on the door 7 and the glass structure 8 is arranged. It is the opening which was done.

The opening 9 and the glass structure 8 constitute a glass window. Numerals 11 denote pivoting mechanisms provided on the mutually facing edges of the glass structure 8, respectively, for pivotally holding the glass structure 8 to the door 7 via a vertical axis so as to be rotatable in the direction of the arrow shown in FIG. Reference numeral 12 denotes a blocking piece provided at an edge of the opening 9 for preventing rotation of the glass structure 8 in a direction opposite to the arrow shown in FIG. 2 at a predetermined position and closing the opening 9.

Reference numeral 13 denotes a lock mechanism, which is locked to hold the glass structure 8 at the opening 9 closed position. Reference numeral 14 denotes an operation panel provided in the above-described car 3, a storage room 15 in which keys (not shown) of the lock mechanism 13 are stored, a door 16 for opening and closing the storage room 15, and a door 16 for locking and performing general maintenance work. A storage lock 17 which is unlocked by a service key and an operation switch 18 arranged on the door 16 are provided.

In the elevator apparatus having a door with a glass window constructed as described above, the glass structure 8 is normally arranged at the closed position of the opening 9 of the door 7 and the locking mechanism 13 is provided.
Are locked and held in the closed position. Operation panel 14
The key of the lock mechanism 13 is stored in the storage room 15 of the
Then, the storage lock 17 is locked, the operation switch 18 is set to the operation side, and the elevator is operated normally.

When cleaning the glass structure 8 of the door 7, the following operation is performed. That is, as a cleaning preparation work, the worker 10 operates the operation panel 1 of the car 3 in the car 3.
The operation switch 18 of No. 4 is set to the stop side, and the door 16 can be opened by unlocking the storage lock 17 with the general maintenance work key. Thereby, the key of the lock mechanism 13 is taken out from the storage room 15. While the storage lock 17 is unlocked, the operation of the operation switch 18 is invalidated, and the elevator is not normally operated even when the storage lock 17 is on the driving side.

Further, when the operation switch 18 is set to the stop side,
When the storage lock 17 is unlocked, the mode is switched to the glass window cleaning operation mode in which the door 7 of the landing doorway 5 is closed and the door 7 of the car doorway 4 is open. Next, with the door 7 of the car doorway 4 closed, the surface of the glass structure 8 of the door 7 of the car doorway 4 inside the car 3 is cleaned by the worker 10 from inside the car 3.

Then, the lock mechanism 13 of the door 7 of the car doorway 4 is unlocked by the key of the lock mechanism 13. In this state, since the key of the lock mechanism 13 does not come out of the lock mechanism 13, the key of the lock mechanism 13 falls out, is lost, or is cleaned while the lock mechanism 13 is unlocked. It is possible to prevent the user from forgetting to close after work. The control device can be configured to automatically switch to the glass window cleaning operation mode when the lock mechanism 13 of the door 7 of the car doorway 4 is unlocked.

Then, the glass structure 8 of the door 7 of the car doorway 4 where the lock mechanism 13 is unlocked is rotated as shown in FIG. In this state, the surface of the glass structure 8 of the door 7 of the car entrance 4 on the landing 5 side is cleaned by the worker 10 from inside the car 3. Next, the car 3 is moved to the door 7 of the car doorway 4 by the operation in the glass window cleaning operation mode.
And the door 7 of the landing entrance 6 is stopped at a position where it does not interlock, and only the door 7 of the car entrance 4 is opened.

Then, the car 3 with the door 7 of the car doorway 4 open is stopped at the landing 5, and a worker 10 works from the inside of the car 3, and the car entrance of the glass structure 8 of the door 7 of the landing doorway 6. The four side surfaces are cleaned. Next, the lock mechanism 1 of the door 7 of the landing doorway 6 is operated by the key of the lock mechanism 13.
3 is unlocked and the lock mechanism 13 is unlocked.
The glass structure 8 of the door 7 is rotated as shown in FIG. In this state, the surface of the glass structure 8 of the door 7 of the landing entrance 6 on the landing 5 side is cleaned by the worker 10 from inside the car 3.

When the cleaning of the surface on the side of the landing 5 is completed, the glass structure 8 of the door 7 of the landing entrance 6 is returned to the position where the opening 9 is closed, and the locking mechanism 13 is locked and its key is locked. Is removed. Next, by the operation in the glass window cleaning operation mode, the car 3 is stopped at the position opposite to the door 7 of the next landing doorway 6, and the glass structure 8 of the door 7 of the opposite landing doorway 6 is cleaned in the above-described manner. You. And
When the cleaning of the glass structures 8 of all the doors 7 is completed, the lock mechanism 13 stores the key in the storage room 15 of the operation panel 14 of the car 3, closes the door 16, and locks the storage lock 17.
With the operation switch 18 on the operation side, the elevator returns to normal operation.

As described above, the inside of the car 3 of the door 7 of the car entrance 4 is cleaned by the worker 10 from the inside of the car 3, and the chain of the door 7 of the car entrance 4 is cleaned. By unlocking the lock mechanism 13 and rotating the glass structure 8, the surface of the door 7 of the car doorway 4 on the landing 5 side of the glass structure 8 is cleaned by the work from inside the car 3.

Then, by the operation in the glass window cleaning operation mode, the car 3 is operated with the door 7 of the car entrance 4 opened and stopped at a position facing the door 7 of the landing entrance 6, and work from inside the car 3 is performed. As a result, the surface of the glass structure 8 of the door 7 of the landing entrance 6 on the side of the car entrance 4 is cleaned, and the locking mechanism 13 is unlocked to thereby clean the glass structure 8 of the door 7 of the landing entrance 6.
Is rotated to clean the surface on the landing 5 side.

Therefore, in order to clean the glass structure 8 provided in the door 7, it is not necessary to open only the door 7 of the landing doorway 6 and work on the car 3. For this reason,
Complicated incidental work such as the worker 10 moving from the car 3 to the landing 5 or getting on the car 3 is eliminated, and the glass structure 8 of the door 7 is easily and quickly cleaned in a short time. The work efficiency can be improved and the cost can be reduced.

When cleaning the glass structure 8 of the door 7,
The elevator is operated in the glass window cleaning operation mode in which the door 7 of the landing entrance 6 is closed and the door 7 of the car entrance 4 is open. For this reason, the glass structure 8 of the door 7 can be easily cleaned without requiring a complicated driving operation, and the work efficiency can be improved and the cost can be reduced.

The lock mechanism 13 of the door 7 of the car doorway 4
The elevator is automatically activated by a preparatory operation for cleaning the glass structure 8 of the door 7, such as unlocking of the storage lock 17 and unlocking of the storage lock 17 with the operation switch 18 of the operation panel 14 of the car 3 on the stop side. The glass window cleaning operation mode is controlled.
For this reason, the glass structure 8 of the door 7 can be easily cleaned without requiring a complicated driving operation, and the work efficiency can be improved and the cost can be reduced.
