  By the pivoting movement of the hinge 27 toward the half-open support position, first, the door body 13 moves from the closed position of the door body 13 shown in FIG. After the door butt 13a of the door body 13 moves to the outdoor B side of the frame 16 on the door butt side after the door butt fitting recess 23 of the frame 16 on the door butt side is disengaged into the opening 20, the door body 13 13 moves to the door butt side, and the door tip 13b of the door body 13 is disengaged into the opening 20 from the door tip fitting recess 24 of the frame portion 17 on the door tip side. As shown in FIG. 3 (b), when the hinge 27 moves to the half-open support position, the half-open support position detection switch 45 is turned on to stop the driving of the opening / closing drive motor 33 of the drive mechanism 32 and to disconnect the clutch 35. To do.

  Thus, the hinge 27 pivots to the half-open support position, whereby the door body 13 moves from the closed position to the half-open position. Even if the door body 13 is moved to the half-open position, the door end return detection switch 55 is in the off state pushed by the inner surface 13c of the door body 13, and the door tip 13b of the door body 13 is in the closed state. Detected.

  Then, as shown in FIG. 3C, when the door body 13 is in the half-open position, the door body 13 can be manually opened with the second support shaft 29 of the hinge 27 as a fulcrum. The opened door body 13 is automatically closed to the half-open position by the action of the door closer 63 unless it is opened to the fully open position. When the door 13 is opened from the half-open position, the door return detection switch 55 is turned on to detect that the door 13 has been opened, and the clutch 27 of the drive mechanism 32 is connected to support the hinge 27 half-open. Hold in position. When the opened door body 13 is closed to the half-open position, the door-end return detection switch 55 is turned off to detect that the door body 13 is closed to the half-open position, and the clutch 35 of the drive mechanism 32 is disconnected.

  As shown in FIG. 2A, when the door body 13 is opened to the fully open position, the locking mechanism of the door closer 63 restricts the opening at the fully open position of the door body 13 and does not automatically close. Lock in the fully open position. The door body 13 locked in the fully opened position is automatically closed to the half-opened position by the action of the door closer 63 if the door closer 63 is moved slightly in the closing direction from the fully opened position to release the locking by the locking mechanism of the door closer 63. .

  Further, in order to close the door body 13 in the half-open position, the door body return detection switch 55 is in the OFF state by operating the indoor A side opening / closing operation part 77 or the outdoor B side opening / closing operation part 83, and the door body. On the condition that the 13 door ends 13b are detected to be closed, the clutch 35 of the drive mechanism 32 is connected and the opening / closing drive motor 107 is driven to move the hinge 27 from the half-open support position to the closed support position. Move to turn.

  By the pivoting movement of the hinge 27 toward the closed support position, first, the door body 13 is moved from the closed position of the door body 13 shown in FIG. The door body 13 is fitted into the door-end fitting recess 24 of the door-end side frame portion 17 and the door butt 13a of the door body 13 is moved from the door-side frame portion 16 to a position within the opening 20 and then the door body 13 is moved to the door. The door butt 13a of the door body 13 is fitted into the door butt fitting recess 23 of the frame 16 on the door butt side. Then, as shown in FIG. 3A, when the hinge position detector 98 detects that the hinge 27 has moved to the closed support position, the drive of the opening / closing drive motor 33 of the drive mechanism 32 is stopped and the clutch 35 is turned off. Disconnect. Immediately after the hinge 27 starts to pivot from the half-open support position to the closed support position, the half-open support position detection switch 45 switches to the off state and detects that the hinge 27 is not in the half-open support position.

  In this way, the hinge 27 pivots to the closed support position, whereby the door body 13 moves from the half-open position to the closed position. When the door body 13 moves to the closed position, the lock mechanism 48 is latched, and the door body 13 is automatically locked.

  Further, since the clutch 35 of the drive mechanism 32 is disengaged at the half-open position of the door body 13, the door body 13 at the half-open position can be manually moved to the closed position. Thus, even when the door body 13 is manually moved to the closed position, the lock mechanism 48 is latched by the door body 13 moving to the closed position, and the door body 13 is automatically locked.

  Next, when applying a door guard to the door body 13 in the closed position shown in FIG. 3A, the door guard lever 78 of the operation panel 76 on the indoor side A is moved from the door guard release position to the upper door guard position. The door guard shaft 59 of the door guard mechanism 58 is engaged with the upper surface of the door body 13 via the wire 60, and the door body 13 enters the door guard state.

  When the door body 13 is in the door guard state, the door body 13 is moved to the half-open position shown in FIG. Can be made.

  At the half-open position of the door 13 on which the door guard is applied, for example, confirmation of a visitor or relatively thin mail through a gap generated between the door tip 13b of the door 13 and the frame 17 on the door tip side. Can be delivered.

  When closing the door body 13 in the door guard state and in the half-open position, by operating the opening / closing operation section 77 on the indoor A side, the door body 13 is moved as shown in FIG. It can be moved to the closed position shown in a).

  When releasing the door guard state of the door body 13, the door guard lever 78 of the operation panel 76 on the indoor A side is moved from the door guard position to the lower door guard release position, so that the door guard mechanism 58 is connected via the wire 60. The door guard shaft 59 is removed from the door body 13, and the door guard state of the door body 13 is released.

  Next, if the door body 13 cannot be opened even if the opening / closing operation part 77 on the room A side is operated due to a failure of the electrical system, the emergency release lever 79 is pushed down from the normal position to the emergency release position. Manipulate. If the door guard lever 78 is in the door guard position by operating the emergency release lever 79, a part of the emergency release lever 79 is engaged with a part of the door guard lever 78 to move the door guard lever 78 to the door guard release position. Then, the door guard shaft 59 of the door guard mechanism 58 is removed from the door body 13 via the wire 60 to release the door guard of the door body 13, and the lock mechanism 48 is unlocked via the wire 49. As a result, since the clutch 35 of the drive mechanism 32 is disconnected, the door body 13 is automatically released to the half-open position without the drive of the opening / closing drive motor 33 by the urging of the emergency release spring of the lock mechanism 48. Then, the door body 13 can be opened manually.

  Further, when the user returns home from the outside, the door 13 cannot be opened and no one is in the room A even if the open / close operation unit 83 on the outdoor side B is operated due to an electrical system failure or the like. In such a case (when the door guard is not applied to the door body 13), the locking mechanism 48 is unlocked via the wire 49 by unlocking and operating the emergency release dial. As a result, since the clutch 35 of the drive mechanism 32 is disconnected, the door body 13 is automatically released to the half-open position without the drive of the opening / closing drive motor 107 by the bias of the emergency release spring of the lock mechanism 48. Then, the door body 13 can be opened manually.

  Next, as shown in FIG. 2 (a), the door body collision avoidance operation for preventing the door butt 13a of the door body 13 opened to the fully open position from colliding with the frame 16 on the door butt side is shown in FIG. This will be described with reference to a flowchart.

  The reason why the door butt 13a of the door 13 opened to the fully open position collides with the frame 16 on the door butt side as shown in FIG. 2 (a) is to open the door 13 further opened to the fully opened position. As shown in Fig. 2 (b), the door closer 63 restricts the opening when an external force is applied or when an external force is applied from the door tip side to the door bottom side of the door body 13. When the hinge 27 is moved from the half-open support position to the closed support position by an external force applied to the body 13, the end face of the door butt 13a of the door body 13 is a frame part on the door butt side as shown in FIG. It will collide with 16 outer surfaces.

  In the door body collision avoidance operation, first, when the door body 13 in the half-open position is opened, the door end return detection switch 55 is turned on to detect the opening of the door body 13 (YES in step 1). Then, the clutch 35 of the drive mechanism 32 is connected to hold the hinge 27 in the half-open support position (step 2), thereby preventing the hinge 27 from shifting from the half-open support position.

  While the door body 13 is open, whether or not the hinge 27 is in the half-open support position is monitored from the state of the half-open support position detection switch 45 (step 3).

  If it is detected that the door body 13 is closed to the half-open position with the hinge 27 in the half-open support position (NO in step 1), the clutch 35 of the drive mechanism 32 is disconnected (step 4).

  Further, when further external force is applied to the door body 13 opened to the fully open position and the hinge 27 moves from the half-open support position toward the closed support position, the half-open support position detection switch 45 is switched from the on state to the off state, and the hinge It is detected that 27 has shifted from the half-open support position (NO in step 3).

  Based on this detection, the opening / closing drive motor 33 of the drive mechanism 32 is driven (step 5), and the hinge 27 is forcibly moved to return to the half-open support position.

  During driving of the opening / closing drive motor 33 of the drive mechanism 32, it is monitored from the state of the half-open support position detection switch 45 whether or not the hinge 27 has returned to the half-open support position within a predetermined time (step 6, 7).

  If it is confirmed from the state of the half-open support position detection switch 45 that the hinge 27 has returned to the half-open support position within a predetermined time (YES in step 6), the opening / closing drive motor 33 of the drive mechanism 32 is driven. Stop (step 8).

  Since the external force applied to the door body 13 is superior to the driving force of the opening / closing drive motor 33, the half-open support position detection switch 45 indicates that the hinge 27 does not return to the half-open support position even after a predetermined time has elapsed. If it is confirmed from this state (NO in step 6), a calling sound is generated and notified by the buzzer 96 of the outdoor operation panel 82 (step 9). Note that an error may be displayed on the display unit 95 for notification.

  When the operator who receives the notification weakens or cancels the external force on the door body 13, the hinge 27 can be returned to the half-open support position by driving the opening / closing drive motor 33.

  In this way, even when an excessive external force is applied to the door 13 in the open state and the hinge 27 is rotated from the half-open support position, the drive mechanism 32 can forcibly return the hinge 27 to the half-open support position. The door butt 13a of the door body 13 in the open state can be prevented from colliding with the door frame 12.

  Moreover, since the drive mechanism 32 moves the hinge 27 to the half-open support position and the close support position according to the operation of the opening / closing operation parts 77 and 83, the door body 13 can be automatically opened and closed between the half-open position and the closed position. The door bottom 13a of the door body 13 in the open state can also be used as a mechanism for preventing the door frame 12 from colliding with the door frame 12.

  When the door 13 in the half-open position is opened, the clutch 35 of the drive mechanism 32 is connected to hold the hinge 27 in the half-open support position, so that the hinge 27 is not easily displaced from the half-open support position and is in the open state. The door butt 13a of the door body 13 can be prevented from colliding with the door frame 12.

  Further, when the open state of the door 13 is detected, it is detected that the hinge 27 is not in the half-open support position, and the drive mechanism 32 moves the hinge 27 to the half-open support position for a certain period of time. When it is detected that the hinge 27 is not in the half-open support position, the buzzer 96 notifies that the door body 13 is stopped from applying an excessive external force, and the door bottom 13a of the door body 13 in the open state is opened. It can be easily prevented from colliding with the frame 12, and an excessive load on the drive mechanism 32 can be reduced.

  A handle for opening and closing the door body 13 may be provided on the inner surface 13c and the outer surface 13d of the door body 13.

  In addition, when the door 13 is opened from the outdoor B, it has an authentication function such as biometric authentication such as a fingerprint or a face, authentication using a non-contact IC, or read authentication of a QR code displayed on a mobile phone or the like. If the authentication is confirmed, an operation of the opening / closing operation unit 83 provided on the operation panel 82 in the outdoor B may be accepted.

  Further, the structure of the door device described in this embodiment is merely an example, and the present contents can be applied to any door that can be automatically opened and closed electrically and can be manually opened and closed.
