Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an elevator installed in a hoistway of a building, and particularly relates to a car door of a car and a hall door of each three-sided frame in this elevator. relates to an entrance/exit device.

(Conventional technology) Conventionally, in elevators installed in buildings such as high-rise buildings,
The number of vehicles in use and the number of entrances and exits for vehicles are extremely large.

On the other hand, although the usage of elevators on standard floors such as the first floor of a building is significantly different from the usage of general floors installed on the second floor and above, hall doors on general floors are also used on standard floors. It is installed in the same scale configuration as the hall door.

(Problems to be Solved by the Invention) However, the above-described elevator entrance/exit device using a hall door differs depending on the time period in which the elevator is used. In other words, the elevator usage time is in the morning,
It reaches its peak during the day and evening (night), and its utilization rate drops sharply at other times. In other words, although elevators are most often used when dispatched, at lunch, and when leaving work, the usage of the standard floor on the 1st floor is much higher than on other general floors above 2nd floor. First, if the hall doors on the general floor are configured on the same scale as the hall doors on the standard floor, it is not only uneconomical, but also has drawbacks such as the door opening/closing time becomes longer and the area used in the elevator hall increases. .

In order to eliminate the above-mentioned drawbacks, the present invention makes the opening/closing operation of the hall door on the standard floor and the hall door on the general floor wider or narrower depending on the degree of use, thereby rationalizing the opening/closing time of the door. To provide an elevator which can be provided at a low cost by considering the economical efficiency when installing the elevator.

[Structure of the invention]

(Means for solving the problems and their effects) The present invention includes:
In an elevator in which the car door of the car is configured with four doors, and each hall door is provided in a three-sided frame on each floor of the building so that it can be opened and closed, the hall door with four doors is installed in the three-sided frame on the standard floor of the building mentioned above. is provided so that it can be opened and closed freely in conjunction with the opening and closing operation of the car door, and a hall door with two doors is provided in the three-sided frame of the general fa so that it can be opened and closed in conjunction with the opening and closing operation of the car door, and the usage rate of the elevator car can be adjusted. Accordingly, the opening and closing operations of each hall door on the standard floor and general floor can be opened and closed in a rational manner.

(Example) Hereinafter, the present invention will be described with reference to an illustrated embodiment.

1 to 4, reference numeral 1 denotes a hoistway formed by penetrating each floor of a building I such as a high-rise building. It is installed so that it can be raised and lowered freely with the hanging lobes of the device, and this car 2
The front opening is equipped with a car door consisting of four doors that can be opened and closed. Further, each floor 4 of the building I is provided with a three-sided frame 5, and this three-sided frame 5 has a hold arrow a with four doors on a standard floor 4a such as the first floor of the building I, for example. is provided so that it can be opened and closed freely in conjunction with the opening and closing operations of the car door 3, and on the general floors 4b above the second floor of the building I, a hold arrow b with two doors is connected to the opening and closing operations of the car door 3. It is provided so that it can be opened and closed freely.

In particular, the car door 3 of the car 2 and each hold arrow a,
The opening/closing operation of the car door 5b can be opened/closed in conjunction with a door cam switch (not shown) attached to the car door 3. Opening/closing control can be performed based on the operating operation performed.

Incidentally, instead of the door cam switch, the car door 3 and the hold arrows a and 6b may be controlled to open and close in 1/2 stroke using an electrical control circuit.

Therefore, the car door 3 of the passenger car 2 and the hold arrow a of the standard floor 4a such as the first floor according to the present invention are opened and closed reasonably widely to shorten the boarding and alighting time because of the high usage frequency, and on the other hand,
Since the hold arrows B on the general floors 4b on the second floor and above are rarely used, they are opened and closed in a small manner in conjunction with the opening and closing operations of the car door 3, thereby shortening the opening and closing operations.

In addition, the car door 3 of the car 2 of the present invention may be configured to have a high-speed opening/closing door and a low-speed opening/closing door among the four doors.

〔Effect of the invention〕

As described above, according to the present invention, the car door 3 of the car 2 is configured with four doors, and each hall door is provided in the three-sided frame 5 provided on each floor 4a, 4b of the building I so that it can be opened and closed. In the elevator, a hold arrow a with four doors is provided in the three-sided frame 5 of the standard floor 4a of the building I, so that it can be opened and closed freely in conjunction with the opening/closing operation of the car door 3, and two doors are provided in the three-sided frame 5 of the general floor 4b. Since the hold arrow b is provided so that it can be opened and closed freely in conjunction with the opening and closing operations of the car door 3, the opening and closing operations of the hold arrows a and 6b can not only be opened and closed rationally according to the degree of use, but also the opening and closing time can be shortened. At the same time, each floor can be used appropriately for forward movement, and furthermore, it has excellent effects such as greatly reducing installation costs.
