Description

  The present invention relates to a revolving door.

  Conventionally, as disclosed in Patent Document 1 and the like, a revolving door that opens and closes a passage between openings by rotating a rotating body having a plurality of door panels is known. As shown in FIG. 10, the revolving door disclosed in Patent Document 1 is spaced by 90 degrees in a space surrounded by a cylindrical wall 63 in which two openings 61 and 62 are formed at positions facing each other. The door panels 65a to 65d are arranged radially. The door panels 65a to 65d are normally in the posture shown in FIG. 10. When the passer detection sensor 67 detects a passer, the door panels 65a to 65d rotate, and after passing the passer, the electromagnetic brake is operated. After stopping at a predetermined position and the door panels 65a to 65d being stationary, the electromagnetic brake is released.

  On the other hand, Patent Document 2 discloses an entrance / exit management device. This entrance / exit management device permits entry / exit by reading the security rank given to the card medium with a reader.

JP 2000-257333 A JP-A-5-314138

  By the way, it is conceivable to provide an authentication device to perform entrance / exit management in the revolving door. In this case, when the passerby is permitted to enter and leave the room, the electromagnetic brake is released, and the door panel can be set to be able to rotate, for example, counterclockwise from the state of FIG. For example, when a passerby who has been authenticated enters from the lower opening 61 and exits from the upper opening 62, the authentication is performed by the authentication device while the door panels 65a to 65d are rotating. Intruders who have not entered can also occur. This unauthenticated person enters the next door panel between the door panels through which the passer-by passes, so that the passer-by exits from the upper opening 62 (for example, when the passer is turned 90 degrees from the state shown in FIG. 10). If the electromagnetic brake is applied to the door, there is a possibility that an unauthenticated person may be trapped between the door panels. When such an abnormality occurs, it is necessary to reversely rotate the revolving door each time so that an unauthenticated person can exit the lower opening 61. In particular, a revolving door has a larger inertia than a general sliding door, so it takes time to reversely rotate. For this reason, if the authentication device is simply provided on the revolving door so as to perform entrance / exit management, a passerby having the right to pass will be awaited, and there is a possibility that good passers-by who have the right to pass cannot be secured.

  Therefore, the present invention has been made in view of such a point, and the object of the present invention is to ensure good passage of passers with pass authority by suppressing the trapping of unauthenticated people. Is to make it.

  In order to achieve the above-mentioned object, the present invention provides a rotating body provided with a rotating body that is rotatably arranged in a space surrounded by a wall portion provided with a first opening and a second opening at positions facing each other. A door, comprising: a braking part for stopping the rotation of the rotating body; and a control means capable of controlling the braking part, wherein the rotating body is provided radially at equal intervals 3 And the control means releases the braking state of the rotating body based on a signal permitting passage from outside, while the rotating body rotates and the outer end of the first door panel And a space between a second door panel following the first door panel and a third door panel following the first door panel is located at a predetermined position in one of the first opening and the second opening. One opening and the second opening. It is a revolving door for controlling the braking portion so that the rotating body in a posture which communicates rests towards.

  In the revolving door of the present invention, the first opening and the second opening are opened and closed by the rotation of the rotating body. However, if a signal permitting passage from the outside is not received, the rotating body is in the basic posture. Maintained in a state. For this reason, the rotating body remains stationary in the basic posture until a passerby appears. Then, when the braking state of the rotating body by the braking unit is released based on a signal permitting passage from the outside, the rotating body can rotate, and the passer-by can pass between the door panels along with the rotation of the rotating body. Since the rotating body is braked by the braking unit so as to be stationary in the next basic posture, the rotating body is stationary in the basic posture, and the door panel does not rotate any more. Therefore, the rotating body is maintained in the basic posture. In other words, in this revolving door, the control means is controlled so that the rotating body stops based on the position of the door panel (the posture of the rotating body).

  Even if a person who is not permitted to pass enters the predetermined space (between the next door panels) inside the wall portion following the passer-by, and the rotating body is stopped in the basic posture, Since both the opening and the second opening are open to the extent that a person can go in and out, the person can go back. That is, even when a person permitted to pass through the second opening exits from the first opening using the space (first space) between the first door panel and the second door panel, the second Since the space (second space) between the door panel and the third door panel communicates with the second opening, even if there is a person who enters the second space without being allowed to pass, the rotating body is in the basic posture When the person stops at the position, the person can go out of the second opening as it is (reversely). Therefore, it is not necessary to control the reverse rotation of the door panel, and for example, it is possible to ensure good passage of a passer who has the authority to pass next to the person.

  In addition to the signal that the authentication device that authenticates whether or not to allow the passage installed in the vicinity of the revolving door transmits the signal that permits the passage based on the authentication result, the administrator or the like leaves the revolving door. This includes data sent from the management room of the building at the same location. In addition, the braking state means that the position is always applied by applying force, and the angle is maintained by the inertial force of the rotating body without urging after the rotating body is stationary, and the rotating body is rotated. It is also included to energize only to maintain a stationary state only when an external force is applied.

  Now, here, the control means is security mode control for controlling the brake unit so that the rotating body is stationary in the basic posture, and the posture different from the basic posture, and the outer end portion of the door panel stopped is the wall portion. It may be configured to include a standard mode control for controlling the braking unit so that the rotating body is stationary in a posture positioned in the vicinity of the edge of the opening.

  In this aspect, while security can be enhanced at night and the like, when security during daytime and the like is not emphasized, the door opening is wide as in the case of a general revolving door, so that the trafficability can be ensured.

  In the standard mode control, since the rotating body is stopped in a posture different from the basic posture, whether the standard mode control is executed according to the posture in which the rotating body is stationary or the security mode control is executed. Can be determined at a glance. Therefore, it can be made easier to determine whether or not the passer-by needs to get permission to pass.

  The posture different from the basic posture is a posture in which the outer end portions of all the door panels are positioned in the vicinity of the edge portion of the opening in the wall portion.

  When four door panels are provided, in the security mode control, the braking unit may be operated so that the rotating body stops at a position rotated 90 degrees.

  In the case where three door panels are provided, in the security mode control, the passerby is placed in a space defined by a door panel whose tip is located near the center of the first opening or the second opening. When entering, the braking portion is operated so that the rotating body stops at a position rotated by 60 degrees, and the tip is positioned near the end of the first opening or the second opening. When the passerby enters the space defined by the door panel, the brake unit may be operated so as to stop at a position rotated by 120 degrees.

  Since it comprised in this way, even if the door panel is an odd number of three or more sheets, it is possible to ensure good traffic of a passing vehicle while suppressing a door accident of an unauthenticated person.

  As described above, according to the present invention, it is possible to secure a good pass for a passerby having a pass authority by suppressing the trapping of an unauthenticated person.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

(First embodiment)
As shown in FIGS. 1 and 2, the revolving door 10 according to the first embodiment is an automatic revolving door and rotates a rotating body 20 disposed inside a wall portion 12 formed in a substantially cylindrical shape. By doing so, the passage between the openings 13 and 14 formed in the wall portion 12 is opened and closed.

  The wall 12 is fixed to the wall of the building. When the wall 12 is fixed to the wall, the wall 12 and the wall are partitioned into an inner space and an outer space of the building. In the present embodiment, the lower side in FIG. 1 is the outside of the building, and the upper side is the inside of the building.

  The wall portion 12 is provided with two openings 13 and 14 each serving as a passage through which a person passes. Each opening part 13 and 14 is formed in the magnitude | size used as the range of about 90 degree | times (the same angle as the angle between door panels) in the rotation direction of the rotary body 20. FIG.

  The wall portion 12 is composed of a pair of arc-shaped portions 15 and 16 each formed in a range of approximately 90 degrees. Each of the arc-shaped portions 15 and 16 is made up of vertical vertices 15a and 16a erected at the center, end erections 15b and 16b erected at both ends, and a transparent plate fitted between the vertices. Shielding portions 15c and 16c. In this embodiment, the opening located on the outside (lower side in FIG. 1) of the building is the first opening 13, and the opening located on the inner side (upper side in FIG. 1) is the second opening 14. .

  The rotating body 20 is rotatably provided in a space surrounded by the wall portion 12, and includes four door panels 20a to 20d that are radially provided at predetermined intervals (90 degrees in the example) in the rotation direction. . The rotating body 20 is disposed so as to rotate about the center of the wall 12, that is, the center of the arcuate portions 15, 16. In other words, the arc-shaped portions 15 and 16 are arranged along the trajectories of the outer end portions of the door panels 20a to 20d. When the rotating body 20 is in the posture shown in FIG. 1, the outer ends of the pair of door panels 20b and 20d facing each other are positioned at the centers of the arcuate portions 15 and 16, respectively, and the other pair of door panels 20a and 20c. The outer end portions are located at the centers of the openings 13 and 14, respectively. When rotated 45 degrees (half the angle of the predetermined interval) from this posture, the outer ends of the door panels 20a to 20d are located at the ends of the arcuate portions 15 and 16, that is, near the edges of the openings 13 and 14. To position.

  As shown in FIG. 2, the revolving door 10 includes an authentication device 25, a drive device 27, an electromagnetic brake 29, activation sensors 31 and 32, occupancy sensors 33 and 34, and a first position that is detection means. The sensor 35, the 2nd position sensor 37 which is a detection means, and the controller 40 which is a control means are provided.

  The authentication device 25 is for managing traffic whether or not to permit passage of the space (passage) in the wall portion 12, and includes a first reading portion 25a on the first opening 13 side and a second opening. And a second reading unit 25b on the unit 14 side. The authentication device 25 collates the information read by the first reading unit 25a or the second reading unit 25b with preset information at the time of executing security mode control, which will be described later. Output a signal to allow traffic. If only room entry management is performed, the second reading unit 25b on the second opening 14 side can be omitted.

  The driving device 27 generates a driving force for rotating the rotating body 20, and is fixed to an unillustrated beam member spanning the upper end of the wall portion 12. The driving device 27 is driven and stopped in response to a signal from the controller 40. In the present embodiment, the driving device 27 drives the rotating body 20 so as to rotate, for example, in the counterclockwise direction in FIG.

  The electromagnetic brake 29 generates a braking force to stop the rotating rotator 20 and keeps the rotator 20 stationary, that is, a braking unit for making the rotator 20 non-rotatable. In accordance with a signal from the controller 40, the state is switched between a state in which the rotating body 20 is kept stationary and a state in which this is released.

  The activation sensors 31 and 32 are configured by area sensors having predetermined detection areas 31a and 32a outside the wall portion 12 in the vicinity of the openings 13 and 14. The activation sensors 31 and 32 output a signal when a person or the like is detected in the detection area. This signal is a signal for starting the rotation of the rotating body 20 during standard mode control described later. In the case where the second reading unit 25b is omitted so as to perform only room entry management, the signal from the inner activation sensor 32 cancels braking by the electromagnetic brake 29 even during security mode control described later. It may be a signal for starting the rotation of the rotating body 20.

  The first position sensor 35 is a sensor for detecting the posture of the rotating body 20 at the time of security mode control, which will be described later. When the door panel 20a to 20d is detected to approach within a predetermined distance range at the time of security mode control, Outputs a signal for braking. For example, the first position sensor 35 is disposed close to the passing position of the outer end of the door panels 20a to 20d at the center position in the width direction of the first opening 13. The first position sensor 35 may be disposed at the center position in the width direction of the second opening 14, or may be disposed in the center of the arcuate portions 15 and 16, or in the vicinity thereof. Alternatively, it may be arranged on a beam member that extends over the wall 12 on the upper side.

  The second position sensor 37 is a sensor for detecting the posture of the rotating body 20 during standard mode control, which will be described later, and the door panels 20a to 20d rotate a predetermined number of times, for example, twice during standard mode control, and then the door panels 20a to 20a. When it is detected that 20d is within the predetermined distance range, a signal for stopping the rotation is output. For example, the second position sensor 37 is disposed in the vicinity of the passing position of the outer end portions of the door panels 20a to 20d at the edge portions (end standings 15b and 16b) of the first opening portion 13. Note that the second position sensor 37 may be disposed on the edge of the second opening 14 (the end-stands 15b and 16b), or on the beam member that extends over the wall 12 upward. May be.

  The occupancy sensors 33 and 34 are sensors for determining whether or not there is a person in the passing area of the door panels 20a to 20d, and as shown in FIG. It is comprised by the area sensor set to 34a. More specifically, the occupancy sensors 33 and 34 include the door panels 20a to 20d whose outer ends are located within the range of the openings 13 and 14, and the openings 13 and 14 on the rotation direction side of the door panels 20a to 20d. A detection area is a predetermined area that is a space that can be entered through a gap between the edge and the door panel 20a to 20d located next to the door panel 20a to 20d. That is, a predetermined area in the space between the door panels 20a to 20d where a passerby who enters through the openings 13 and 14 enters is set as a detection area. The in-room sensors 33 and 34 output a signal when a person or the like is detected. This signal is not used during standard mode control, which will be described later, but is a signal for starting rotation of the rotating body 20 during security mode control, which will be described later.

  The functions of the controller 40 include a switching control means 40a for switching the control mode, a braking control means 40b for controlling the electromagnetic brake 29, and a drive control means 40c for controlling the rotating body 20. Yes. The switching control means 40 a is a function for switching the braking control mode of the rotating body 20, security mode control for releasing the braking state according to the authentication result by the authentication device 25, and detection results by the start sensors 31 and 32. Switching between standard mode control that rotates in response to. This switching may be performed automatically according to the time, or may be switched according to a signal from a manual switch (not shown) or the like.

  The posture in which the rotating body 20 is stopped is different between the security mode control and the standard mode control. Specifically, during security mode control, as shown in FIG. 1, the basic posture (stopping posture) of the rotating body 20 is such that the outer ends of a pair of opposed door panels 20a to 20d are respectively arc-shaped portions 15 and 16. On the other hand, the outer end portions of the other pair of door panels 20a to 20d are positioned in the center of the openings 13 and 14, respectively. In other words, for example, the left-side door panel 20d (second door) of the lower door panel 20a (first door panel) in FIG. 1 is located at a predetermined position in the first opening 13 and continues to the first door panel 20a. The space between the door panel) and the upper door panel 20c (third door panel) following the door panel communicates with the second opening 14. In this basic posture, the outer end portions of one door panel 20b, 20d (door panel 20b, 20d in a posture extending in the left-right direction in the figure) are adjacent to the left and right arc-shaped portions 15, 16, respectively. The rotating body 20 becomes the basic posture again when rotated 90 degrees from this basic posture.

  On the other hand, during the standard mode control, the rotator 20 is maintained in a posture (second basic posture) different from the basic posture, as shown in FIG. In other words, in the second basic posture, the outer ends of the two opposing pairs of door panels 20a to 20d are both positioned at the ends of the arcuate portions 15 and 16, that is, near the edges of the openings 13 and 14. It is posture. The second basic posture is deviated by 45 degrees in the rotation direction from the basic posture at the time of security mode control. Therefore, the second position sensor 37 is disposed at a position where a posture rotated 45 degrees with respect to the posture of the rotating body 20 detected by the first position sensor 35 can be detected.

  The braking control means 40b (controller 40) outputs a signal for releasing the braking state when receiving a signal permitting passage from the authentication device 25 during security mode control. This signal is received by the electromagnetic brake 29.

  The braking control means 40b stops the rotating body 20 when receiving a signal from the first position sensor 35 during the security mode control and when receiving a signal from the second position sensor 37 during the standard mode control. Signal for output. These signals are received by the electromagnetic brake 29. Therefore, during the security mode control, the rotating body 20 stops in the basic posture shown in FIG. 1 and enters the braking state, while during the standard mode control, the rotating body 20 stops in the second basic posture shown in FIG.

  The drive control means 40c drives the drive device 27 when receiving a signal output from the occupancy sensors 33 and 34 until a predetermined time elapses after receiving a signal from the authentication device 25 during security mode control. To do. Thereby, the rotating body 20 rotates. On the other hand, if the signals from the in-room sensors 33 and 34 are not received within a predetermined time after the signal from the authentication device 25 is received, the controller 40 outputs a signal for setting the rotating body 20 in a braking state. .

  The drive control means 40c drives the drive device 27 when receiving signals output from the start sensors 31 and 32 during the standard mode control. Thereby, the rotating body 20 rotates. At this time, the rotating body 20 is rotated by a predetermined rotation (for example, two rotations). Further, when the drive control means 40c receives signals output from the start sensors 31 and 32 during the standard mode control, the drive control means 40c continues to rotate the rotating body 20.

  Here, the operation of the revolving door 10 according to the first embodiment will be described. 4A to 4D illustrate the operation of the revolving door 10 during security mode control, and FIGS. 4E to 4G illustrate the operation of the revolving door 10 during standard mode control. Explain.

  At the time of security mode control, the rotating body 20 is in the basic posture as shown in FIG. In this state, when a passerby appears and, for example, information read by the first reading unit 25a of the authentication device 25 matches a state stored in advance, the authentication device 25 outputs a signal permitting passage. As a result, a signal for releasing the braking state is output from the controller 40, the electromagnetic brake 29 is operated, and the braking state of the rotating body 20 is released.

  When the passerby enters the wall portion 12 through the first opening portion 13, the occupant sensor 33 detects it (FIG. 4B). Thereby, since the drive device 27 rotates the rotary body 20, the passerby can go to the 2nd opening part 14 according to it, and can get out of the rotary door 10 (FIG.4 (c) (d)). And when the rotary body 20 rotates 90 degree | times, since the door panel 20d is detected by the 1st position sensor 35, it will be in a braking state in the position. At this time, the rotating body 20 is again in the basic posture. If the controller 40 does not receive the signals from the occupancy sensors 33 and 34 within a predetermined time after receiving the signal from the authentication device 25, the controller 40 determines that the passer-by has not entered, and the driving device 27. The rotating body 20 is brought into a braking state without driving the.

  When switched to the standard mode control, the rotating body 20 is maintained in the second basic posture (FIG. 4E). In the standard mode control, for example, when a passerby is detected by the outside activation sensor 31, a signal for driving the rotating body 20 is output from the controller 40. Thereby, the rotating body 20 is driven and rotated by the driving device 27. Thereby, the passer-by can pass through the gap between the door panels 20a and 20b and exit from the second opening 14 (FIGS. 4F and 4G). And after rotating only the predetermined rotation speed, when the 2nd position sensor 37 detects door panel 20a-20d, the electromagnetic brake 29 will act | operate and the rotary body 20 will be stopped. In the standard mode control, the brake force of the electromagnetic brake 29 is released after a predetermined time has elapsed since the rotating body 20 is stationary, and the stationary state is maintained only by the inertial force of the rotating body 20.

  As described above, in the revolving door 10 of the first embodiment, the passage between the first opening portion 13 and the second opening portion 14 is opened and closed by the rotation of the rotating body 20, but the passage is permitted. If no signal is received, the three or more door panels 20a to 20d provided radially at equal intervals in the rotation direction are maintained in the basic posture. For this reason, the door panels 20a to 20d are in the basic posture until a passerby appears. And if the braking state by the electromagnetic brake 29 is cancelled | released based on the signal which permits passage, the rotary body 20 will be able to rotate and a passer-by will pass. And when the rotary body 20 becomes the next basic attitude, it will be in a braking state by the electromagnetic brake 29, and the door panels 20a-20d will not rotate any more. Therefore, the rotating body 20 is maintained in the basic posture. In other words, the revolving door 10 is controlled so that the rotating body 20 is brought into a braking state based on the positions of the door panels 20a to 20d (the posture of the rotating body 20).

  If a person who is not permitted to pass enters the predetermined space (between the next door panels 20a to 20d) inside the wall portion 12 following the passer-by, the door panels 20a to 20d when the rotating body 20 assumes the basic posture. Even in a braking state, in the basic posture, both the first opening 13 and the second opening 14 are open to the extent that a person can enter and exit, so that the person can return. That is, a person who has been permitted to enter enters the first opening 13 and uses the space (first space) between the first door panels 20a to 20d and the second door panels 20a to 20d to form the second opening. 14, the space (second space) between the second door panels 20 a to 20 d and the third door panels 20 a to 20 d communicates with the first opening 13, so that the passage is not permitted. Even if there is a person who enters the two spaces, the person can go out from the first opening 13 when the rotating body 20 stops in the basic posture. Therefore, the control for rotating the door panels 20a to 20d in the reverse direction is not necessary, and for example, it is possible to ensure good passage of a passerby having the right to wait next to the person.

  Moreover, in the first embodiment, the braking control of the rotating body 20 can be switched between the security mode control and the standard mode control. Therefore, the security can be enhanced by using the authentication device 25 at night and the daytime. When security such as the above is not emphasized, the passability of the passerby can be prioritized by using the activation sensors 31 and 32.

  In the first embodiment, in the standard mode control, the rotating body 20 is stopped in a posture different from the basic posture, so that the standard mode control is executed according to the posture in which the rotating body 20 is stationary. It can be determined at a glance whether the security mode control is being executed. Therefore, it can be made easier to determine whether or not the passer-by needs to get permission to pass.

  In the first embodiment, the outer end portions of all the door panels 20a to 20d are positioned in the vicinity of the edges of the openings 13 and 14 in the wall portion 12 in a posture stopped in the standard mode control.

  Further, in the first embodiment, when the security mode control is performed, the brake state is set in a state where the outer end portions of the first door panels 20a to 20d are located at predetermined positions of the opening portion 13 located on the outdoor side. Therefore, the width of the opening 13 becomes narrow during security mode control. For this reason, when a person enters the opening 13 on the outdoor side, it becomes difficult for a plurality of persons to enter between the same door panels 20a to 20d, and to effectively prevent an unauthenticated person from entering. Can do.

  In the first embodiment, the positions of the door panels 20a to 20d in the rotational direction are detected by the position sensors 35 and 37, and the rotating body 20 is brought into a stationary state by the detection. Therefore, the door panels 20a to 20d when braking is performed. Can be stabilized.

  In the first embodiment, in the standard mode control, the rotation of the rotator 20 is controlled based on the signals of the start sensors 31 and 32. You may make it rotate.

(Second Embodiment)
As shown in FIG. 5, the revolving door 10 according to the second embodiment includes a touch switch 50 unlike the first embodiment, and the activation sensors 31 and 32 including area sensors are omitted. In the second embodiment, only differences from the first embodiment will be described.

  The touch switch 50 has a sensor unit (not shown) provided on each of the door panels 20a to 20d, and outputs a signal when a person touches the sensor unit.

  When receiving a signal from the touch switch 50 during the security mode control and the standard mode control, the drive control unit 40c drives the drive device 27. The driving device 27 generates a driving force for driving the rotating body 20 when a person touches the sensor unit of the touch switch 50. The driving device 27 generates a driving force that can rotate the rotating body 20 by the driving device 27 itself. However, instead of the touch switch 50, a sensor that can detect that an external force is applied to the rotating body 20, for example, an encoder that detects the rotation of the rotating body 20 or a person that is pressing the rotating body 20 is detected. A weight sensor or the like may be used, and in this case, the driving device 27 may generate a driving force that assists a person in rotating the rotating body 20.

 The touch switch 50 outputs a signal in response to a passer's operation. When the signal is received by the controller 40, the driving device 27 is driven to rotate the rotating body 20. Therefore, in this case, the touch switch 50 functions as an activation sensor.

  On the other hand, when an encoder that detects the rotation of the rotating body 20 or a weight sensor that detects that a person is pushing the rotating body 20 is used, these function as an activation sensor.

  In the second embodiment, when the passerby is authenticated by the authentication device 25 during the security mode control, the braking state of the rotating body 20 is released, and the passerby enters the passing area of the door panels 20a to 20d and touches it. When the sensor unit of the switch 50 is pressed (when an encoder that detects the rotation of the rotating body 20 or a weight sensor that detects that a person is pressing the rotating body 20 is used, the door panels 20a to 20d are pressed), the driving device 27 generates a driving force (FIGS. 6A and 6B). And a passerby moves with rotation of the rotary body 20, and goes outside through the opening part 14 on the opposite side (FIGS. 6C and 6D). And if the door panel 20d is detected by the 1st position sensor 35, since the rotary body 20 will be made still and will be in a braking state, the rotary body 20 will stop in a basic attitude again.

  On the other hand, at the time of the standard mode control, the rotating body 20 assumes the second basic posture as shown in FIG. Then, a passerby enters the passing area of the door panels 20a to 20d and presses the sensor part of the touch switch 50 (an encoder that detects the rotation of the rotating body 20 or a weighted sensor that detects that a person is pressing the rotating body 20) When the door panels 20a to 20d are pushed, the rotating body 20 rotates and the passerby can get out of the opening 14 on the opposite side (FIGS. 6F and 6G).

(Third embodiment)
As shown in FIG. 7, in the revolving door 10 according to the third embodiment, the second position sensor 37, the driving device 27, and the driving control means 40 c are omitted, and the rotating body 20 rotates by being pushed by a person. It has a configuration. In the third embodiment, only differences from the first embodiment will be described.

  In the third embodiment, it is possible to switch between security mode control and standard mode control in the same manner as the previous embodiment. And at the time of standard mode control, if a person pushes the door panels 20a-20d, since the rotary body 20 can be rotated anytime, it can always pass.

  Since the rotating body 20 does not rotate by itself, human power is required even when the standard mode control is switched to the security mode control and the basic posture in the security mode is set. That is, when the mode is switched from the standard mode control to the security mode control, the position of the door panels 20a to 20d is changed by the first position sensor 35 after the rotating body 20 is rotated by the passage of a person instead of changing its posture by itself. By detecting this, the rotator 20 is controlled to the basic posture. Thereafter, the rotating body 20 is maintained in the basic posture.

  Further, the present invention is not limited to the above-described embodiment, and the present invention has an advantage that security can be easily added and improved only by adding the first position sensor 35 and the controller to the existing revolving door.

(Fourth embodiment)
In the first to third embodiments, the rotating door 10 includes the rotating body 20 having the four door panels 20a to 20d. However, unlike these, in the fourth embodiment, FIGS. 8A and 8B are used. As shown in FIG. 3, the rotating body 20 has three door panels 20e to 20g. In the fourth embodiment, only differences from the first embodiment will be described.

  The openings 13 and 14 are formed at positions facing each other, and are sized to be in a range of approximately 60 degrees (half the angle between the door panels) in the rotation direction of the rotating body 20. In other words, each arc-shaped part 15 and 16 of the wall part 12 is formed in the range of 120 degrees, respectively. The second position sensor 37 is disposed at a position where it can detect a posture rotated 30 degrees with respect to the posture of the rotating body 20 detected by the first position sensor 35.

  The first position sensor 35 is provided in each of the first opening 13 and the second opening 14. As described later, this is to detect a posture rotated by an angle between door panels and to detect a posture rotated by half the angle between door panels.

  The door panels 20e to 20g are provided radially at intervals of 120 degrees. The basic posture (first basic posture) of the rotating body 20 at the time of security mode control is such that one door panel 20e (first door panel) is the first as shown at the bottom of FIG. A left upper door panel 20g (second door panel) that is located at a predetermined position (center position) in the first opening 13 and that follows the first door panel 20e, and a right upper door panel 20f (third door panel) that follows this. The space in between is in a posture to communicate with the second opening 14. In this basic posture, the outer end portions of one door panel 20f and 20g are close to the left and right arc-shaped portions 15 and 16, respectively. The rotating body 20 is again in the basic posture when rotated 120 degrees from this basic posture.

  In the rotating body 20, the state shown at the top in FIG. 8A also corresponds to the basic posture (first basic posture). That is, in this state, one door panel 20f (first door panel) is located at a predetermined position (center position) in the second opening 14, and the lower right door panel 20e (second door panel) following the first door panel 20f. ) And the subsequent lower left door panel 20g (third door panel) is in a posture to communicate with the first opening 13. Therefore, in the fourth embodiment, the basic posture is also obtained by rotating by 60 degrees (half the angle between the door panels) from the basic posture shown at the bottom of FIG.

  On the other hand, in the basic posture (second basic posture) at the time of standard mode control, the outer end portions of the two door panels 20e and 20g are in one arcuate portion 15 as shown at the bottom of FIG. The position is located near the edge, that is, in the vicinity of the edge of the openings 13 and 14, and the outer end of the other door panel 20 f is located at the center of the other arcuate part 16. Therefore, in the second basic posture, none of the outer end portions of the door panels 20e to 20g are located in the openings 13 and 14.

  In the revolving door of the fourth embodiment, at the time of security mode control, the rotating body 20 is in the first basic posture as shown in the bottom diagram of FIG. In this state, when a passerby having a right of passage appears, the braking state is released. When the passer enters the space between the two door panels 20e and 20f through the opening 13, the drive device 27 rotates the rotating body 20. . The passerby can accordingly move toward the second opening 14 and exit the revolving door 10. Then, when the rotating body 20 is rotated 60 degrees from the basic posture, the door panel 20f is detected by the first position sensor 35 on the second opening 14 side, so that the braking state is set at that position. At this time, the rotating body 20 is again in the basic posture.

  On the other hand, during the standard mode control, as shown in FIG. 8B, the rotating body 20 is in the second basic posture. In this state, when a passerby appears and enters the space between the two door panels 20e and 20f through the opening 13, the driving device 27 rotates the rotating body 20. The passerby can accordingly move toward the second opening 14 and exit the revolving door 10. And when the rotary body 20 rotates 180 degree | times, since the door panel 20g is detected by the 2nd position sensor 37 by the side of the 2nd opening part 14, it controls to stop at the position. At this time, the rotating body 20 is again in the second basic posture. Note that, for example, control may be performed so as to stop after two rotations.

FIG. 9A is an explanatory diagram when a passerby entering from the second opening 14 side appears, unlike FIG. 8A. FIG. 9B is an explanatory diagram when a passerby entering from the first opening 13 side appears in the last position (the top in the figure) of FIG. 8A. . FIG. 9C is an explanatory diagram when a passerby entering from the second opening 14 side appears in the last posture (the top in the drawing) of FIG. .

  In FIG. 9A, when a passerby with a passage authority enters the space between the two door panels 20 f and 20 g through the second opening 14, the drive device 27 rotates the rotating body 20. When the rotator 20 rotates 120 degrees, a space between the door panels 20f and 20g opens in the first opening 13. At this position, the door panel 20g is detected by the first position sensor 35, and the driving device 27 stops the rotator 20. Let In this state, the passer-by can exit through the first opening 13.

  In FIG. 9 (b), when a passerby with a passage authority enters the space between the two door panels 20 e and 20 g from the first opening 13, the drive device 27 rotates the rotating body 20. When the rotating body 20 rotates 120 degrees, a space between the door panels 20e and 20g opens in the second opening 14, and the door panel 20e is detected by the first position sensor 35 at this position, and the driving device 27 stops the rotating body 20. Let In this state, the passer-by can exit through the second opening 14.

  In FIG. 9 (c), when a passerby with a passage authority enters the space between the two door panels 20 f and 20 g through the second opening 14, the driving device 27 rotates the rotating body 20. When the rotator 20 rotates 60 degrees, a space between the door panels 20f and 20g opens in the first opening 13. At this position, the door panel 20g is detected by the first position sensor 35, and the driving device 27 stops the rotator 20. Let In this state, the passer-by can exit through the first opening 13.

  In addition, even if it is the structure which has the three door panels 20e-20g, it is also possible to set it as the structure similar to 2nd Embodiment and 3rd Embodiment.
