The accommodation sidewall doors (1) are accommodated in the anti-rotation direction at the time of opening, and are made open in both right and left directions in conjunction with rotation of a pivoted door. In the event that the opening width may pose a danger to inrush with the door closed, the inrush blocking sidewall doors (10) are closed in the anti-rotation direction and from both right and left sides, thereby making an effect to give sense of urgency and get diverted from inrush. The inrush blocking sidewall doors (10) are not fully closed, but stopped with a human body with left, resulting in no excessive force being applied to a human body. The inrush blocking sidewall doors (10) are small in inertial force due to small width and lightweight, and have degrees of freedom in the accommodation direction, which prevents excessive force from being applied to the human body. For ensuring safe operation, the traffic is monitored with a television camera to supervise the access to a dangerous region. The traffic is analyzed by a computer-based image analysis to predict a degree of risk in advance. The risk-aversive control for operation of the pivoted door is performed through the advanced computer-based risk prediction.

Description

Automatic revolving door that opens and closes in both directions

The present invention is an automatic revolving door that opens and closes in both the left and right directions, quickly securing the opening width necessary for people to enter and exit at the entrance, and reducing the congestion at the entrance by increasing the time that people can enter and exit, The present invention relates to an automatic revolving door that smoothes the flow of people.

The present invention relates to an automatic revolving door provided with a means for preventing intrusion when the revolving door is closed and the intrusion becomes a dangerous width and not applying excessive force to the body.

Further, the present invention relates to an automatic revolving door in which high-risk avoidance control is performed by monitoring the movement of a person for safe operation of the automatic revolving door and predicting the approach of a person to a dangerous area in advance.

Large automatic revolving doors driven by motors, etc., are often used as buildings grow larger, but they are used by an unspecified number of people, from infants to the elderly, and require a high level of safety. .

Large-sized automatic revolving doors allow a large number of people to go in and out, so at the entrance and exit, the opening width necessary for the passage of people is secured quickly, and the time that people can enter and exit is increased to reduce congestion. .

As a safety measure in the operation of automatic revolving doors, methods such as detecting abnormalities with sensors etc. and controlling the rotation of the door are adopted, but predicting human behavior and predicting approach to the dangerous area in advance etc. There is a need for further improvements in safety.

The revolving door closes only because it is uniquely closed, so it is different for each person to judge that the intrusion is a dangerous width, and there are also some gunless people who try to jump in forcibly depending on the personality, Some people are inferior in judgment, such as drunks, especially children, but there are not enough special considerations.
JP 2002-030866 A JP 2001-032642 A JP 2002-194959 A JP 05-000873 A

The automatic revolving door is inside the arc-shaped side walls provided on the left and right of the entrance of the building, and inside the both side walls by the revolving door body that is composed of four, three or two doors radially around the rotation axis. The space is divided into four sections, three sections, or two sections, and the revolving door body rotates in one direction around the rotation axis, but the area of the section is large as a large automatic revolving door that many people enter and exit. An automatic revolving door composed of three or two doors is suitable for widening.

At the time of opening of the entrance / exit, the time required for the person to enter and exit is lengthened by quickly securing the opening width necessary for the person to enter and exit like a double door that opens in both directions.

As a large-sized automatic revolving door for many people to enter and exit, it is necessary to widen the opening width of both arc-shaped side walls and reduce the congestion at the entrance and exit as well as the area of a large section, ensuring the opening width quickly. And make the time available for people to go as long as possible.

In addition, there is a need for a means to avoid dangers such as pinching between the side walls and the revolving door body, but since the revolving door has a large inertial force, it is predicted in advance that people will approach the danger area and the revolving door is By controlling, a high level of avoidance means is provided to prevent danger.

When the revolving door closes and the intrusion becomes a dangerous area, it is equipped with a stub that prevents the intrusion and prevents excessive force from being applied to the human body.

The previous invention (Japanese Patent Application No. 2004-139493) is one method for solving this problem, but the present invention is further improved.

The revolving door has a space that can be divided into sections by both sides of the arc and the revolving door that rotates in one direction (counterclockwise), but a large number of people can enter and exit at once as a large automatic revolving door. Since it can do, the rotation door of the rotation door body comprised by the three doors or two doors from which the area of the space used as a division becomes large is suitable.

Three-door or two-door revolving doors are suitable as large revolving doors with a large area, but both have their merits and demerits, and it is up to the designer to decide which one to use.

The disadvantage of the three-door revolving door is that the area of the compartment is narrower than that of the two-door revolving door, but the advantage is that it will not stop the flow of people because it will not close the opening of the side wall, and it will be smooth It becomes the flow of people.

The advantage of the double door revolving door is that the area of the section is wide, but the disadvantage is that the opening of the side wall is closed and the flow of people is stopped once.

Both of the revolving doors can be provided with arcuate sleeve doors that are inscribed in the both side walls at the outer end of the door, thereby widening the width of the opening on the side wall.

The space divided into sections by both side walls and the revolving door body enters and exits from the opening on the open side by rotation of the revolving door body in one direction (counterclockwise) around the rotation axis, and is closed by rotation. After that, the opening on the opposite side is opened and the person enters and exits, and the person can enter and exit the building via the rotating moving space.

Since the revolving door body rotates in one direction, the opening of the side wall can be divided into compartments, and a side where the opening starts and a side where the opening ends (the side to be closed) are formed.

The automatic revolving door needs to be always closed between both side walls with a revolving door body so that the space that forms the revolving door does not communicate with the inside and outside of the building.

For this purpose, the arc angle including the side wall and the sleeve door 4 is required to be 120 degrees in the case of the three-door door, and the arc angle including the side wall and the sleeve door 4 is required in the case of the two-door door. It needs to be 180 degrees.

By making it possible to store a part of the width of the side wall, it is possible to widen the opening width of the side wall and to quickly secure the opening width necessary for people to enter and exit. The side wall is fixed to the fixed side wall 2 and the storage side wall door 1. The storage side wall door 1 that can be stored on the side where the opening of the side wall starts is provided, and the storage side wall door 1 can be stored on the side of the fixed side wall 2 in the direction opposite to the rotation direction.

As a timing for storing the storage side wall door 1, the storage side wall 1 is stored in a direction opposite to the rotation direction after the entrance side of the compartment is closed.

Since the rotation direction of the sleeve door 4 of the revolving door body and the storage direction of the storage side wall door 1 are opposite to each other, it is possible to quickly secure the opening width necessary for people to enter and exit like a double door that opens in both the left and right directions. I can do it.

As a timing for returning the stored storage side wall door 1, it is made to return following the sleeve door 4 of the subsequent door body.

An intrusion prevention side wall door 10 that can be stored is provided on the closed side of both side walls. When the door closes and the intrusion becomes a dangerous width, the intrusion prevention door 10 is closed in the counter-rotating direction and closed from both the left and right sides to give a sense of urgency. Stop intrusion.

The intrusion prevention side wall door 10 is not closed, but is stopped with the human body width remaining, or inverted and stored at a low speed (about half the rotational speed).

The intrusion prevention side wall door 10 has a degree of freedom in the storage direction (rotation direction), and an excessive force is not applied to the human body by releasing the force to the intrusion prevention side wall door side.

Since the intrusion prevention side wall door 10 is narrow and light, it can move quickly because the inertial force can be made small, and it is possible to prevent excessive force from being applied to the body by installing a sensor in the front and reversing it. I can do it.

As a danger avoidance means in the operation of the revolving door, it is equipped with

TV cameras

8 and 9 to monitor the movement of the person, analyze the movement of the person by image analysis with a computer, predict the approach of the person to the dangerous area in advance, Control of operation such as deceleration and stoppage of the revolving door is performed based on the advanced risk prediction judgment.

By providing the side wall door 1 on the side wall and storing it in the counter-rotating direction when the space to be partitioned is opened, it is possible to quickly secure the opening width necessary for people to enter and exit, thus increasing the time that can be entered and exited. Widening makes it possible to reduce congestion at the doorway.

When the door is closed and the opening width becomes dangerous, the door is closed together with the intrusion prevention side wall door 10 from both the left and right directions, thereby giving a sense of tightness and stopping the intrusion.

Since the intrusion prevention side wall door 10 has a degree of freedom in the storage direction (rotation direction), the force escapes in the storage direction and no excessive force is applied to the body.

The intrusion prevention side wall door 10 does not completely close, but does not cause any harm to the body in order to stop while leaving the body width or to reversely retract at low speed.

TV cameras

8 and 9 are provided as danger avoidance means in the operation of revolving doors, monitoring the movement of people, predicting the movement of people by computer analysis and predicting the approach to the dangerous area in advance. It is possible to safely control a revolving door that has a force and requires a stopping distance.

By providing the storage side wall door 1 on the side wall and storing it in the counter-rotating direction on the side of the fixed side wall 2, the opening width of the entrance / exit can be secured quickly, and the time that people can enter / exit can be lengthened, thereby reducing congestion at the entrance / exit.

When the door closes and the opening width becomes dangerous, the entry is prevented and the safety is improved.

TV cameras

8 and 9 are provided as risk avoidance means, monitoring human movements, predicting approach to dangerous areas by computer analysis, performing advanced risk avoidance control using computers, and using computer learning functions Measure the improvement of safe operation of the revolving door.

In addition, the angle of the arc is 120 degrees, and in the case of the two-door revolving door provided with the sleeve door 4, the angle of the arc is obtained by adding the fixed side wall 2, the storage side wall door 1 and the sleeve door 4. 180 degrees, and storage and return are for detection provided at the storage end and return end. It is controlled by the sensor signal and is performed by a motor, etc., so that the opening width can be secured quickly, so that the time that people can enter and exit can be lengthened, and the opening width of the side walls can be widened. It is possible to facilitate the entry and exit of people and is characterized by the storage side wall door 1 that can store a part of the width of the arc-shaped side wall in the direction opposite to the rotation direction. Three- and two-door automatic revolving doors with sleeve doors 4, characterized in that they are made of revolving door bodies that rotate in both directions, and that are open in both directions.
For safe driving of automatic revolving doors, the movement of people entering and exiting and the state of people are monitored by TV cameras 8 and 9, and human movements are predicted by image analysis using a computer, so that people can approach the danger area in advance. As a result, the TV camera 8 is used as a place for monitoring by installing a TV camera, and the space that becomes a partition is closed at the opening of the side wall. The TV camera 9 is provided in a place where the person who enters and exits can see and the TV camera 9 is provided in a place where the revolving door body can be seen to fall forward in order to prevent the revolving door body and the floor from being caught. A method of safely driving an automatic revolving door by predicting a high degree of danger based on the analysis of the movement of the vehicle and performing operation control such as deceleration and stop according to the degree of danger by advanced danger avoidance control.
In order to ensure the safety when the revolving door of the first embodiment is closed, an intrusion prevention side wall door 10 is provided on the opposite side of the storage side wall door 1 of both the fixed side walls 2 so that the door is closed and the opening width becomes dangerous. Sometimes it closes in the counter-rotating direction and closes in both the left and right directions along with the rotation of the revolving door body to prevent intrusion. After closing, the revolving door body is accommodated along with the rotation of the revolving door body. ) Inwardly (or circumscribed), and can be stored like an arcuate sliding door. The rotating door body rotates inwardly of the inside of the sliding door, and the fixed side wall 2, the storage side wall door 1, and the intrusion prevention side wall door 10. The angle of the arc including the sleeve door 4 and the door is approximately 180 degrees for the two doors, and approximately 120 degrees for the three doors. However, the intrusion prevention side wall door 10 does not completely close, leaving the body width The distance from the position closed by rotation of the rotating door body to the storage end of the intrusion prevention side wall door 10 is longer than the stopping distance of the rotating door. However, the intrusion prevention side wall door 10 releases the force by giving freedom in the storing direction, so that the revolving door detects an obstacle and stops. However, even at the revolving door stop distance, it is excessive for the body. Two doors and three doors with sleeve doors 4 or three doors, which are designed to prevent force from working, and have intrusion prevention side wall doors 10 closed from both directions to prevent entry. Automatic revolving door.
