  The string drive unit 37 and the solenoid 38 are controlled by a control unit (not shown) together with the shutter drive unit 23, and contact information of the contact detection switch is transmitted to the control unit. The controller automatically opens and closes a shutter 21 and a door frame 32, which will be described later, by operating a remote controller (not shown).

  Hereinafter, the effect of the shutter 1 with an automatic door of this embodiment is demonstrated. 1 and 2 show that the shutter 21 of the shutter unit 2 is in a closed state, and that both the door main body 31 and the door frame 32 of the door unit 3 are in a closed state.

  FIG. 3 shows an open state of the door body 31. In this state, the door main body 31 functions as an entrance door, and the user can enter and exit the building. The shutter 21 and the door frame 32 are also closed in this state.

  Next, the opening of the shutter 21 and the door frame 32 will be described in order to allow the vehicle to enter and exit. The user presses the release button on the remote control. The opening instruction information is transmitted from the remote controller to the control unit, and the control unit first drives the shutter driving unit 23 to wind up the shutter 21 to open the shutter.

  Next, the control unit controls the door frame driving unit 34. That is, the solenoid 38 is driven to remove the rod 38B from the hole 32B. The door frame 32 locked by the solenoid 38 is shifted to the open state by the urging force of the first hinge 35 (see FIG. 4). At this time, the string body 37D wound around the pulley 37C is pulled out. The transition of the door frame 32 to the open state is completed by the stopper 40 (see FIG. 5).

  When the entry / exit of the vehicle is over and the shutter 21 and the door frame 32 are closed, the user presses the close button on the remote control. Closing instruction information is transmitted from the remote control to the control unit, and the control unit drives the string driving unit 37 to wind the string 37D around the pulley 37C in order to shift the door frame 32 to the closed state. As described above, the force for closing the door frame 32 by the string driving unit 37 is larger than the urging force for shifting the door frame 32 to the open state by the first hinge 35.

  When the door frame 32 is moved to the closed position by the string drive unit 37, the contact detection switch 39 contacts the upper end of the door frame 32, and the contact information is transmitted to the control unit. With this contact information, the control unit stops the string body driving unit 37 and simultaneously drives the solenoid 38 to penetrate the rod 38B into the hole 32B, thereby closing the door frame 32. Furthermore, the control part shutter drive part 23 is driven, the shutter 21 is lowered | hung, and the shutter part 2 is made into a closed state.

  In the above embodiment, a member such as the angle 210 of Patent Document 2 does not protrude outside the building, and the wire 208 of the same document is not exposed outside the building. Further, since the first hinge 35 has an urging mechanism, a member such as the angle 210 is not required. In addition, the structure inside the hinge of the 1st hinge 35 is an illustration, and if the same function is fulfilled, the structure will not ask | require.

  Furthermore, since the 2nd hinge 36 has a damper mechanism, the impact when the door frame 32 will be in an open state is relieved. In addition, the structure inside the hinge of the 2nd hinge 36 is an illustration, and if the same function is fulfilled, the structure will not ask | require.

  Furthermore, the string drive unit 37 includes a string 37D, a pulley 37C that winds the string 37D, a reduction gear unit 37B, and a motor 37A. Therefore, the closing speed of the door frame 32 can be easily adjusted, and the size is relatively small. It can be driven by a motor. Therefore, low manufacturing costs can be realized.

  It is possible to further provide a one-way clutch in the string driving unit 37 of the above embodiment. Since the one-way clutch cancels the torque in the reverse rotation direction of the motor 37A when the door frame 32 is opened, an undesirable load on the reduction gear portion 37B can be reduced.

  Furthermore, since the door frame 32 can be maintained in the closed state by the closed state maintaining means by the solenoid 38 and the hole 32B, there is an advantage that the processing to the door frame 32 is minimized.

  Furthermore, since the closed state of the door frame 32 is detected by the contact detection switch 39, the manufacturing cost can be reduced.

  Further, the string drive unit 37 can be configured to be driven with a weak driving force when the door frame 32 is rotated from the closed state to the open state by the first hinge 35 as the biasing means. . That is, when the string driving unit 37 is driven with a weak driving force, the opening speed of the door frame 32 is reduced. For this reason, even when the 2nd hinge 36 does not have a damper mechanism, the impact at the time of the door frame 32 becoming an open state can be relieved.

  Furthermore, since the shutter drive unit 23 and the door frame drive unit 34 perform the opening / closing operation in conjunction with each other, it is possible to prevent the door frame 32 from malfunctioning in the open state and the closed state with respect to the opening operation and the closing operation of the shutter 21. Can do.

  Furthermore, since the shutter drive unit 23 and the door frame drive unit 34 can be instructed to open and close by a single remote controller, the user instructs the shutter drive unit 23 and the door frame drive unit 34 with separate controllers. It is not necessary and is very convenient.

  In the above embodiment, the stopper 40 is provided by means for limiting the hinge opening angle provided inside the first hinge 35 or the second hinge 36, for example, a projection or the like provided at a predetermined angle provided on the rotating part of the hinge. Can be substituted. Moreover, the restriction | limiting of the opening angle of the door frame 32 by the stopper 40 can be substituted also by length adjustment of the string 37D.
