In addition, the expansion door driving unit 250 may be fixed so that each of the driving pulleys 252 corresponding to the sliding doors 242, 243 and 244, respectively, is parallel to each other on a single shaft connected to the shaft of the motor 251, and the driving pulley 252 ) each diameter is formed to be large in proportion to the moving distance of the sliding doors 242, 243, 244 corresponding to the driving pulley 252, respectively, so that the belt 253 using the same number of revolutions of the single motor 251, the moving distance of each By making it different, the moving distance of each of the sliding doors 242 , 243 , 244 can be made to have a difference suitable for opening and closing.

On the other hand, in the case of the sliding door (242, 243, 244), the left and right triple sliding doors (242, 243, 244) can be configured to open and close at the same time. Alternatively, only one of the triple sliding doors 242, 243, 244 of the left and right triple sliding doors 242, 243, 244 may be configured to individually open and close.

When the second motion detection unit 270 installed on both upper portions of the sliding doors 242, 243, 244 detects an occupant, the sliding doors 242, 243, 244 respectively installed on both sides are opened accordingly, and configured to maintain an open state as necessary. It may also be configured to close if there is no subsequent entrant during the opening. In addition, the sliding doors 242 , 243 , and 244 may be configured to reopen if there is a subsequent entrant while they are being closed, and may be opened again if a safety-related sensor operates during the closing process. These sliding doors (242, 243, 244) can also be selected by operation in an open state.

In addition, the sliding doors (242, 243, 244) is a single operation is possible, it may be configured to open and close the left and right sliding doors (242, 243, 244) individually. This can be configured to perform opening and closing operations of the sliding doors 242, 243, 244 corresponding to the second motion detection unit 270 located above each of the sliding doors 242, 243, and 244 when an occupant is detected. In addition, when the sliding doors 242 , 243 , and 244 are individually operated, if there is no follow-up person, the opening may be stopped and the operation may be blocked. At this time, if there is a subsequent entrant or a sensor related to safety operates, the closed sliding doors 242 , 243 , and 244 may be configured to open again.

According to the present invention, as a revolving door in which the openings 114, 115, 214 and 215 are greatly expanded by improving the 2 Wing Revolving Door System, for example, the expanded doors 140 and 240 having a diameter of 4,200 mm may be installed. If the operation mode of the expansion doors 140 and 240 is selected to open and close the passages 116 and 216, when the expansion doors 140 and 240 are opened, vehicles can pass through, evacuation of a large number of people in case of a fire, large furniture can be brought in and out, and the like, and the revolving door assembly It is also possible to use as a revolving door by rotation of (120,220). At this time, it is possible to move two or more wheelchairs for the disabled, pass through a moving truck in a large store, and allow multiple people to move with their luggage at the same time. Also, the opening degree of the openings 114 and 115 may be proportional to the diameter of the bottom plate 112 .

According to the automatic revolving door having an extended door according to the present invention as described above, it is possible to make it excellent in blocking the inflow of outside air, thereby reducing energy consumption for cooling and heating, and it can be used as a non-rotating automatic door.

In addition, according to the present invention, through the adoption of an expansion door capable of extending the access passage, it is possible to enter and exit a large moving object, such as a vehicle or large cargo, if necessary. It is possible to solve the difficulty of providing a separate large entrance, and by facilitating the evacuation of a large number of people in an emergency such as a fire, it is possible to minimize damage to human life.

In addition, according to the present invention, due to the structure in which the rotation is supported not only in the upper part but also in the lower part, vibration or shaking of the revolving door is minimized during the rotation operation, so that the stable operation can be performed.

Although the present invention has been described with reference to the accompanying drawings as described above, various modifications may be made without departing from the spirit of the present invention. Accordingly, the scope of the present invention should not be limited to the above-described embodiments, but should be defined by the claims and their equivalents.
