Description

  The present invention relates to a revolving door device including a revolving door that is disposed at a doorway of a building and can automatically rotate.

  There are many revolving door devices that are provided at the entrance and exit of a building and that include a revolving door that can automatically rotate and a substantially cylindrical fixed wall that surrounds the revolving door. Such revolving door devices often have a configuration in which the front end of the revolving door slides and rotates on the inner surface of the fixed wall. With such a configuration, outside air flows into the building or the interior of the building. This prevents the atmosphere from flowing out and reducing the air conditioning efficiency. However, in the revolving door device having such a configuration, there is a possibility that a passing user may be caught between the fixed wall and the revolving door that automatically rotates in the revolving door device.

  Under such circumstances, a revolving door device has been proposed that prevents an accident caused by being pinched between the fixed wall and the revolving door that automatically rotates (see Patent Document 1). In this rotary door device, a sleeve portion having a predetermined length on the radially outer side of the door arranged radially from the central axis in the vertical direction is formed of a separate member and connected to the door portion on the center side by a hinge. ing. As a result, even if a user who goes in and out of the building through the revolving door device is about to be sandwiched between the door that automatically rotates and the fixed wall, the sleeve part is removed from the door that is rotated by the hinge. Since it bends, it can prevent being pinched between the door which rotates automatically, and a fixed wall.

  However, although the above-mentioned revolving door device can prevent itself from being sandwiched between the automatically rotating door and the fixed wall, the automatic rotating door once contacts the user. It was unsatisfactory for users because of the anxiety of being caught between them.

Further, a yellow zone 82 is formed in a portion partitioned by the side doors 30 (30a and 30b or 30c and 30d) in the inside and outside direction of the building and outside the rotation locus circle of the rotary door 20 in the rotary space 80.
The floor 110 of the yellow zone 82 is provided with a rubber mat switch 83 that detects the load loaded on the upper surface and turns the switch ON, and is electrically connected to the control device 60. However, the means for detecting the evacuation of the user to the yellow zone 82 is not limited to the rubber mat switch 83, but an infrared sensor using a near-infrared reflected wave, a heat ray sensor for detecting heat rays, or blocking of emitted light is used. You may comprise with the photoelectric sensor etc. which were made.

  The air curtain device 70 sucks air from the air suction port 71 a provided in the outer surface 71 by the clockwise rotation of the rotary fan 73 provided in the internal air passage 72, passes through the air passage 72, and enters the bottom surface 74. A strip-shaped air flow that is wide in the left-right direction (the width direction of the passage opening 11) is jetted downward along the outer surface of the passage opening 11 from the air outlet 74 a provided. As a result, the outer surface of the passage opening 11 is covered with an invisible air curtain 75 as shown by a one-dot chain line in FIG. 5, and movement of the atmosphere passing through the passage opening 11 can be suppressed.

Next, going into and out of the building passing through the revolving door device 1 having the above-described configuration will be described with reference to FIGS. 6 and 7, which are explanatory views using plan views of the revolving door device 1.
When the user 200 passes through the revolving door device 1 and enters and exits the building, as shown in FIG. 6A, the user 200 passes through the passage opening 11 and rotates in a counterclockwise direction in plan view. In accordance with the rotation of 20, it enters the space between the front and rear door panels 22. When entering the revolving door device 1, for example, a user 200 a exiting from the building to the outside of the building is on the left side of FIG. 6A, and a user 200 b entering the building from the outside of the building is FIG. 6A. As shown on the right side, the user 200 goes to the revolving door device 1 and enters the revolving door device 1 from the right side of the pole 12 and labeled IN on the floor 110.

  At this time, if there is no abnormality in the operation of the revolving door device 1, the LED 13 emits green light. If a trouble has occurred in the revolving door device 1, the LED 13 emits red light. Therefore, the user 200 checks the color emitted by the LED 13 and enters the revolving door device 1.

  The user 200 that has entered the revolving door device 1 proceeds forward in accordance with the rotation of the revolving door 20, and exits from the revolving door device 1 through the front passage opening 11 as shown in FIG. 6 (b).

  Here, as shown in FIG. 7A, when the user 200a enters the revolving door device 1, the user 200a is sandwiched between the entrance-side side door 30c and the door panel 22 of the revolving door 20 rotating from behind. Even if the user 200b is likely to be sandwiched between the front side door 30b and the door panel 22 rotating from the back when the user 200b leaves the revolving door device 1, As shown in FIG. 4, the torque limiter 34 provided in the side door 30 is operated, and the side door 30 pivots in the direction before the rotation of the revolving door 20, so that the user 200 can move between the side door 30 and the door panel 22. The revolving door device 1 can be passed without being sandwiched between them.

Further, as shown in FIG. 7B, as the revolving door 20 rotates, the user 200 in progress of the revolving door device 1 cannot follow the revolving door 20 for any reason, and the door panel approaches from behind. When the user 200 is about to be pushed forward to 22, the user 200 can retreat to the yellow zone 82 by moving from the respective traveling direction to the right radially outward direction. At this time, the control device 60 detects the retreat of the user 200 via the rubber mat switch 83 installed on the floor surface of the yellow zone 82 and reduces the rotation speed of the revolving door 20.
As a result, the user 200 retreated to the yellow zone 82 can easily return to the side of the revolving door 20 and pass through the revolving door device 1 in accordance with the rotation of the revolving door 20 whose rotational speed has decreased.

  6 and 7, during the rotation of the revolving door 20, there is nothing blocking the passage openings 11a and 11b inside and outside the building in the revolving door device 1, so that the atmosphere inside and outside the building flows into and out of each other. It becomes possible. However, in the present embodiment, the air opening 75 provided by the air curtain device 70 is provided in the passage opening 11, so that the inflow and outflow of the atmosphere inside and outside the building is suppressed. Therefore, the outflow of the air-conditioned atmosphere in the building or the inflow of outside air can be suppressed, and a decrease in air-conditioning efficiency due to the provision of the rotary door device 1 can be prevented.

Next, the control of the revolving door device 1 will be described with reference to FIG. 8 showing a block diagram of the structure of the revolving door device 1 and FIG. 9 showing the control flow of the revolving door device 1.
The revolving door device 1 is configured by connecting a control device 60 that controls the driving device 40 between a driving device 40 that rotates the revolving door 20 and a power supply device 50 that supplies power for operating the driving device 40. is doing. Further, the rubber mat switch 83, the time counter 42, the rotary door sensor 41, and the operation switch 61 are connected to the input side of the control device 60, and the LED 13 and the floor hinge 33 are connected to the output side of the control device 60. Further, between the control device 60 and the drive device 40, a shutoff device 62 that electrically shuts off the supply of the power supply device 50 is connected.

  First, when a start instruction signal input by the administrator of the revolving door device 1 using the operation switch 61 is received (step s1), the control device 60 of the revolving door device 1 causes the user 200 to enter the yellow zone 82. It is checked via the rubber mat switch 83 whether or not it has been retracted. When the rubber mat switch 83 has not detected the retreat of the user 200 to the yellow zone 82 (step s2: Yes), the lock of the floor hinge 33 of the side door 30 and the driving device 40 of the rotary door 20 is released (step s4) The driving device 40 is started (step s5), the rotational speed of the revolving door 20 is adjusted to a preset rotational speed of 65 cm / s, and normal operation is started (step s6).

  When the retreat of the user 200 to the yellow zone 82 is detected via the rubber mat switch 83 (step s2: No), the retreat detection via the rubber mat switch 83 is repeated a predetermined number of times at a predetermined time interval (step s3: Yes). ) When the predetermined number of times is exceeded (step s3: No), the rotary door operation process is terminated.

  When the retreat of the user 200 to the yellow zone 82 is detected by the rubber mat switch 83 during normal operation of the revolving door device 1 (step s7: Yes), the control device 60 causes the drive device 40 to rotate the revolving door 20 at a rotational speed. Is controlled to be reduced to 1/3 of the preset normal speed (step s8).

  When the retraction by the rubber mat switch 83 is not detected after the rotational speed of the driving device 40 is reduced (step s9: Yes), the control device 60 adjusts the rotational speed of the rotary door 20 to the normal speed in the driving device 40 (step s10). ). If the retraction by the rubber mat switch 83 is continuously detected after the rotation speed of the revolving door 20 is reduced (step s9: No), the revolving door operation process is terminated.

  The retraction of the user 200 to the yellow zone 82 by the rubber mat switch 83 is not detected (step s7: No). In the revolving door device 1 during normal operation, the control device 60 detects the torque limiter from the revolving door sensor 41 built in the driving device 40. When the operation is detected (step s11: Yes), the time counter 42 starts counting the operation time of the torque limiter (step s12). Here, the operation of the torque limiter means that a predetermined torque is applied to the torque limiter and the rotation of the rotary door 20 is stopped when a load in the direction opposite to the rotation direction is generated on the rotating rotary door 20 for some reason. Indicates the state.

  When the count by the time counter 42 exceeds a predetermined time set in advance (step s13: Yes), that is, when any reason for stopping the rotation of the rotary door 20 is not performed within the predetermined time, the shut-off device 62 is activated (step s14), and the rotary door operation process ends. In addition, when the count by the time counter 42 does not exceed the preset predetermined time (step s13: No), the process returns to the normal operation (step s6).

  During normal operation of the revolving door device 1, the manager of the revolving door device 1 inputs an operation using the operation switch 61 when, for example, the business hours in the building end and only the so-called service entrance becomes accessible. When receiving the rotation door stop instruction signal (step s15), the control device 60 senses the rotation position of the rotation door with the rotation door sensor 41, and each door panel 22 and each side door panel 32 as shown in FIG. The vertical door is formed, that is, the rotary door 20 is rotated to the rotation position where the rotary door 20 has an X shape in plan view, and the electric lock of the driving device 40 is operated and locked at the rotation position (step s16). Thereby, the person concerned with a building can go in and out of a building using the side door 30 outside the diameter of the locked revolving door 20 as a service entrance.

  Further, in the locked state of the revolving door 20, when the administrator of the revolving door device 1 receives a side door lock instruction signal input by using the operation switch 61 (step s17), the control device 60 causes the floor hinge. The side door 30 held in the radially inward direction by 33 is locked by actuating the electric lock of the floor hinge 33 (step s18), and the rotary door operation process is terminated. Thereby, the doorway of this building can be locked completely.

  By the revolving door device 1 having the above-described configuration and flow, the user 200 who enters and exits the building through the revolving door device 1 enters the revolving door device 1 but cannot follow the rotation of the revolving door 20. Even if it exists, since it can evacuate to the yellow zone 82 in the rotation space 80, the rotation door apparatus 1 can be utilized safely.

  When the rubber mat switch 83 detects that the user 200 has retreated to the yellow zone 82, the control device 60 reduces the rotation speed of the revolving door 20. However, it is possible to easily return to the revolving door 20 that rotates at a low rotation speed.

  Further, for the user 200 retreating to the yellow zone 82, the rotation speed of the revolving door 20 rotating in front of the eyes is lower than the normal speed, and therefore, the rotating revolving door 20 is in front of the eyes. It is possible to evacuate to the yellow zone 82 without anxiety.

  Further, even when the user 200 enters the revolving door device 1 or exits from the revolving door device 1, even when the user 200 is about to be sandwiched between the side door 30 and the revolving door 20, the load exceeds a predetermined value. When pressed, the side door 30 pivots around the side door shaft 31, so that it can be prevented from being sandwiched between the side door 30 and the revolving door 20. Further, since the predetermined load is set to an appropriate load that does not cause injury even if it acts on the user 200, an accident such as the user 200 being injured before the side door 30 pivots can be prevented.

  Furthermore, for example, even when a user 200 with luggage is sandwiched between the revolving door 20 and the cylindrical wall 10, a load greater than a second predetermined load is generated on the revolving door 20. The torque limiter incorporated in the drive device 40 interrupts the rotational force transmitted to the rotary door 20 and stops the rotation of the rotary door 20. Therefore, it is possible to prevent a load greater than the second predetermined load from affecting the user 200 sandwiched between the revolving door 20 and the cylindrical wall 10.

  Moreover, since the rotary door 20 can be reversely rotated by applying a force greater than the second predetermined load in the reverse rotation direction of the rotary door 20, the user 200 is interposed between the rotary door 20 and the cylindrical wall 10. Even if the user 200 is caught for some reason, the user 200 can be rescued.
