Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator system, and more particularly to an elevator system in which the opening / closing position of an entrance / exit is improved.

[0002]

2. Description of the Related Art In an elevator apparatus having entrances and exits on a plurality of floors, the openings of the entrances and exits on each floor are usually provided at the same position on all floors, and the doors on all floors are set in the same opening and closing range. ing. On the other hand, a technique for changing the opening / closing range of the door on each floor has been already proposed in, for example, Japanese Utility Model Laid-Open No. 3-28181.

[0003]

In the above-mentioned conventional technique, since the entrances and exits having the same opening width are formed at the same positions over the entire floors, the same is true around the entrances and exits over the entire floors. It was necessary to secure a large space, and layout design near the entrance and exit was limited.

It is an object of the present invention to provide an elevator system which allows a degree of freedom in layout design in the vicinity of the entrance / exit of each floor.

[0005]

In order to achieve the above object, the present invention displaces the opening position of at least one entrance / exit in the opening / closing direction of the door with respect to the opening position of another entrance / exit, or at least one entrance / exit. The opening width of the mouth is different from the opening width of the other entrances and exits.

With the above structure, since the opening position and opening width of the entrance / exit can be changed for each floor, the layout design in the vicinity of the entrance / exit of each floor can be freely performed for each floor.

In the present embodiment, the car door 11 is
As shown in FIG. 2, the four doors 11a to 11d are opened at the center, while the ground doors 15 to 15 on the ground floors 3a to 3d are opened.
18, the first floor 3a is the central double opening of the four doors 15a to 15d like the car door 11, the second floor 3b is the central double opening of the two doors 16a and 16b, and the third floor 3c is
Single door 17 is a single door open, 3rd floor 18a-
It is an anomalous double opening of 18c. And each door 15a-15d of the 1st floor 3a, the 3rd floor 3c, and the 4th floor 3d, 17, 18 is.
The width dimensions of a to 18c are the same, and the door 16 on the second floor 3b
The width dimensions of a and 16b are the other doors 15a to 15d, 17, and 1.
It is formed wider than the width dimension of 8a to 18c.

Further, the entrance / exit 1 on the ground floors 3a to 3d side
The opening widths W1 to W4 of 3a to 13d differ depending on the width and the number of each door, and in addition, as shown in FIGS. 1 to 3, the opening position, that is, the opening / closing position of the hall door is set to the center line 20 of the car door 11. On the other hand, the first floor and the second floor are opened evenly on the left and right, the third floor is opened on the right side, and the fourth floor is opened on the left side.
Different door opening and closing directions.

Further, as shown in FIG. 2, the door engaging device 19 has two central doors 11b, 1 on the car door 11 side.
Engaging pieces 21a and 21b protruding from 1c are provided, and the number and width of doors on the hall door side are different depending on each floor. Therefore, in the first floor 3a, the engaging pieces 21a on the car side,
21b, a pair of engaging elements 22a, 22b are provided so as to project from the central double doors 15b, 15c, and in the second floor 3b, a pair of engaging elements 21a, 21b on the car side are provided. The engaging members 23a, 23b of the double door 16a, 16
On the 3rd floor 3c, which is provided so as to project from b, a pair of engaging elements 24 that engage with the engaging pieces 21b on the car side is a single door 17
On the 4th floor 3d, a pair of engaging elements 25 are provided which are engaged with the car-side engaging pieces 21a and 21b.
a and 25b are provided so as to project from the double doors 18b and 18c.

With the above construction, the hall doors 15 to 18 engaged with both or one of the car doors 11 on each floor move the same distance as the car doors 11 to open and close the entrances 13a to 13d. To do. For example, 3rd floor 3
In c, when the car door 11 is opened as usual, the door 11b becomes the door 11a and the door 11c becomes the door 11d as shown by the chain line.
And the entrance width W of the car 5 is fully opened. At this time, the hall door 17 engaged with the engagement piece 21b of the door 11c moves the same distance as the door 11c to fully open the entrance / exit 13c. The same engagement is performed on the other floors to open and close the respective entrances / exits 13a, 13b, 13d.

In the above embodiment, the opening / closing range of the car door 11 of the car 5 is constant regardless of the opening / closing opening of each floor. For example, in the third floor 3c shown in FIG. As shown by the chain line, when the car door 11 of the car 5 is fully opened, the interior of the hoistway is completely visible from within the car 5, which reduces the design effect and is dangerous for passengers.

Therefore, regardless of the entrance / exit width W of the car 5, in the present embodiment, as shown in FIG. 4, the opening / closing range of the car door 11 of the car 5 is set to the opening / closing widths W1 to W4 of each floor.
The above problem is solved by controlling in accordance with. That is, on the first floor 3a, since the entrance width W of the car 5 and the opening width W1 of the entrance / exit 13a are the same, the car door 11
Is driven so as to open and close the entire range of the entrance / exit width W of the car 5, and on the second floor 3b, the car door 11 is connected to the entrance / exit 1
It is driven so as to open and close within the range of the opening width W2 of 3b, and it is driven so as to open and close the car door 11 within the range of the opening width W3 of the entrance / exit 13c on the third floor 3c, and the entrance / exit for the fourth floor 4d. By storing the control device 10 so as to drive the car door 11 to open and close within the range of the opening width W4 of 13d, the car door 11 can be opened and closed according to the entrance and exit of each floor, It is possible to prevent the design effect from being lowered due to the car door 11 being opened too much and prevent the passengers from being in danger.

However, since it may not be possible for the passenger in the car 5 to predict how much floor the car door 11 will open, a display means 26 such as a voice display or a visual display is installed in the car 5. However, when the landing floor approaches, the opening range of the car door 11 is displayed to prevent the deterioration of service.

By the way, in the above embodiment, the car door 1
1, the landing doors 14 to 18 are engaged and opened and closed. However, if the car door 11 and the landing doors 14 to 18 can be opened and closed synchronously, for example, the landing doors 14 to 18 and the car door 11 Any type of door driving means may be used, such as a dedicated driving device for each of the above.

As described above, according to this embodiment, the opening / closing positions of the entrance / exit ports 13B, 13a to 13d, the opening / closing position of the entrance / exit port, the entrance door width, etc. are changed for each floor. Therefore, it becomes possible to design the layout around the platform according to the purpose of use, the conditions, and the environment of each floor, and it is possible to give the layout design flexibility. That is, for example, in FIG. 1, the first floor 3a has a large number of customers in a hall or the like, so it is used as an Oma exit, and the second floor 3b has a relatively large number of users in a hotel lobby or the like, but the appearance is important. The layout can be designed as a wide two-door unit. Furthermore, 3
The floor 3c is a single door with a narrow width because it is a floor for private use or a safe where there are few users or it does not usually stop, and the 5th floor 3d is designed to allow large luggage to be put in and taken out in a warehouse etc. In addition, it can be designed as a triple door.

As described above, according to the present embodiment, the opening width and the opening position of the entrance / exit can be changed for each floor, so that the embodiment shown in FIGS. Can be applied.

First, in the embodiment shown in FIG. 5, the wall 27 of the building is connected to the entrance / exit 2 on a specific floor or all floors.
The structure is extended to the door stop side of the hall door 29 that opens and closes 8, and the extended wall 27 is used to use part of the hall as a space such as a living room or a warehouse.

Further, in the embodiment shown in FIG. 6, the wall 27 of the building is extended toward the center of the car door 11 of the car 5 on a specific floor or all floors, and both sides of this wall 27 are extended. The entrances and exits 30a and 30b having a narrow frontage are formed, and the landing doors 31a and 31b are provided in the entrances and exits 30a and 30b.
32b. However, when the car door 11 is opened, the landing door 31 facing both living rooms 32a and 32b
If inconvenience occurs if both a and 31b are opened at the same time, there is no problem if the opening and closing is controlled by the code or time zone so that only one hall door is opened.
