Abstract

(57) [Summary] [Purpose] It is inconvenient that the conventional double-deck elevator cannot get on and off between odd and even floors. The purpose is to obtain a double deck elevator that solves this problem. [Structure] Stairs are provided so that the cars can move between the upper and lower cars of the double deck. In addition, depending on the passenger's entry / exit floor, a device is provided to guide the passengers through a speaker or display, and if necessary, control the opening / closing time of the doors so that the passengers can get on / off the service on all floors. .

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double deck elevator in which two cars are vertically connected.

[0002]

2. Description of the Related Art A conventional double deck elevator will be described with reference to FIGS.

In recent years, the height of buildings and the scale of the buildings have increased, and it has become necessary to transport a large number of personnel in the buildings.

In order to transport a large number of personnel in an elevator, it is sufficient to increase the number of elevators and increase transportation efficiency. However, there is a limit to increase the number of elevators because the elevator hoistway occupies a large area in the building.

Therefore, there is a method of transporting a large number of personnel by increasing the number of passengers in one elevator. That is,
This is to connect more than one car up and down and to transport more than twice as many people at a time as compared with the case of one car. There is an elevator in which two cars are connected in this way (hereinafter referred to as a double deck elevator).

In FIG. 6, a normal elevator car 1 and a normal car 2 are vertically connected so as to be integrated into one elevator car 3
Make up. An elevator that can transport twice as many passengers as a normal passenger can be provided by placing passengers in the car 1 and the car 2, respectively.

In the stop floor of the car 3 of the double-deck elevator having such a structure, the cars 1 and 2 are connected vertically, so that the car 1 is on the odd floor of each floor of the building 4 (FIG. 5), but the even floor is The operation method of stopping the car 2 every other floor, which is the stop floor, will be adopted.

[0008]

Therefore, in such a double-deck elevator, passengers riding on the car 1 from the odd floor can only reach the stop floor of the car 1, that is, the odd floor. Similarly, passengers in car 2 can only reach the even floors by elevator. For example, if you want to go from the 12th floor to the 7th floor, you must take the elevator car 2 from the 12th floor to the 6th or 8th floor and go to the 7th floor by stairs.

Therefore, an operating method in which the double deck elevator is stopped on each floor is also conceivable. However, stopping each floor would reduce the elevator transportation efficiency. In other words, two cars move at the same time.
Car 2 will stop on the 5th floor when passengers on the 4th floor go to the 4th floor. At this time, if there are no passengers on the 5th floor in the car 2, this operation is a wasteful movement for the passengers in the car 2. Since this can occur on all floors, overall transport efficiency is reduced and the advantages of double deck elevators are lost. Further, since only the car 1 can be stopped on the lowermost floor and only the car 2 can be stopped on the uppermost floor, it is not possible to move all floors by the elevator, as described above.

In order to solve this drawback, it is an object of the present invention to obtain a double-deck elevator that can move all floors by an elevator without lowering transportation efficiency.

[0011]

For this reason, the present invention provides a double-deck elevator having a structure in which two cars are vertically connected to each other and integrally formed, and the cars can be freely moved between the cars. In addition, by determining the stop floor by the car call button operated in the car, it is determined which car can be stopped, and in some cases it is notified to the passenger that car movement is required, and the travel time Considering the above, a control device for controlling the door opening time of the elevator entrance is provided.

[0012]

With such a structure, the passengers can move between the upper and lower cars and notify the passengers which car can reach the destination floor, and also control the door opening time of the doorway, so that the passengers can take all the measures. You can go to the floor.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described based on the embodiments shown in FIGS.

In FIG. 1, stairs 5 are provided between the car 1 and the car 2. As a result, the car 1 and the car 2 can be freely moved. Even when the car is running, it is possible to move between the upper and lower cars 1, 2.

It is now assumed that the car 1 on the odd floor and the car 2 on the even floor are responsive double deck elevators (FIG. 5).
reference). As an example, if the destination floor of the passenger getting on from the first floor is the sixth floor, the passenger first gets into the car 1 and specifies the sixth floor of the car call button 6. However, since only the car 2 can be stopped on the 6th floor because it is an even floor, it is necessary to move this passenger to the upper car 2, and the speaker 7 "6
Please go up the stairs to the floor and get off the car at the top. " In addition, the door opening time on the 6th floor of the car 2 is set longer than usual in consideration of the moving time for moving up and down the stairs, and control is performed to ensure the getting on and off of passengers moving from the car 1.

The control device 8 will be described (flowchart in FIG. 4).

First, it is determined whether the car is stopped or not stopped on the floor designated by the car call button 6 operated in step S1. That is, in the above-mentioned case, when a passenger boarding the car 1 on the first floor selects the button on the 6th floor of the car call button 6 of the car 1, the 6th floor is a non-stop floor, and therefore the elevator control device 8 The process S2 is performed. That is, an announcement such as "Please go up the stairs to the 6th floor and get off the car at the top". This guides passengers to the car 2. At the same time, the door opening time on the 6th floor of the car 2 is extended in consideration of the moving time on the stairs (process S3). For example, the time until the elevator car 1 arrives at the 5th floor, that is, when the car 2 arrives at the 6th floor, the passengers are still moving, so the door opening time is extended to ensure that the passenger can reach the destination floor. To

With the double-deck elevator having such a structure, the passengers of the elevator can be transported to all floors. That is, the service to the elevator users can be improved without deteriorating the usefulness of the double deck elevator capable of transporting a large number of personnel.

In the above embodiment, the announcement is used as a means for informing the passengers of the movement between the cars, but the same effect can be obtained by displaying such a notice on the display device.

Further, although the present embodiment is a double-deck elevator in which two elevator cars are connected, the same operation can be performed even when the number of cars is three or more.

If the stairs provided in the car have an allowance in the hoistway, the stairs can be provided outside the car floor area to some extent, so that the passenger capacity can be reduced.

[0022]

According to the present invention, the service floor range is increased without lowering the operation efficiency, so that the utility value of the double deck elevator is increased.
