The operation part 10 has a linear main arm 11 and a link 12 coupled to the top of the main arm 11 so as to be disposed perpendicularly to the main arm 11.

The lower end of the main arm 11 is coupled to rotate integrally with the shaft of the reducer 22 to be described later.

The link 12 has an action link 12a fixedly coupled to the main arm 11, and a support link 12c rotatably provided to the wall 101 via the wall bracket 104.

The action link 12a is formed with a guide groove 12b along the longitudinal direction in the region of the support link 12c.

The support link 12c is formed along the height direction of the opening door 102 with a pin hole 12d at the end of the wall bracket 104.

The support link 12c having such a configuration is partially inserted into the guide groove 12b and coupled to the wall bracket 104 through the pivot pin 106 fixed through the pin hole 12d and fixed to the wall bracket 104. do.

The opening / closing drive unit 20 is an opening / closing drive motor 21 and a speed reducer fixed to the opening door 102 through a door bracket 105 having a translator shape attached to the lower side of the opening door 102 and the inner surface action link 12a. 22 and a switching circuit portion (not shown) incorporated in the box structure 103.

Next, the open / close control unit 34 controls the forward driving voltage to be supplied to the open / close drive motor 21 from the switching circuit unit (not shown) when the on signal is input from the open / close on / off switch 33.

When the forward drive voltage is supplied to the open / close drive motor 21, the shaft of the reducer 22 rotates in a counterclockwise direction (when looking at the reducer shaft from the main arm side), and accordingly, the opening door 102 is opened through the operating part 10. The opening force required to rotate to the open position where the access space is formed is transmitted. The insertion section for the guide groove 12b of the support link 12c decreases while the door 102 moves to the open position (see Fig. 6).

On the other hand, the open / close control unit 34 does not perform the supply control of the forward drive voltage when the off signal is input from the open / close on / off switch 33.

Next, the opening / closing control unit 34 has a predetermined distance or more from the sliding door 102 based on detection signals from the outer proximity sensor (not shown) and the inner proximity sensor 32 when the door 102 is in the open position. Determine whether the person is out of the door.

In the case where the person is out of the opening door 102 by a certain distance and the on signal is input from the opening / closing on / off switch 33, the opening / closing control part 34 is reversed from the switching circuit part (not shown) to the opening / closing drive motor 21. The driving voltage is controlled to be supplied.

When the reverse drive voltage is supplied to the open / close drive motor 21, the shaft of the reducer 22 rotates clockwise (when looking at the reducer shaft from the main arm side), and accordingly, the opening door 102 is operated through the operating unit 10. ) Transmits the closing force necessary to rotate to the closed position where the access space is extinguished. The insertion section for the guide groove 12b of the support link 12c increases while the door 102 moves to the closed position (see Fig. 5).

On the other hand, the open / close control unit 34 does not perform the supply control of the reverse drive voltage when the off signal is input from the open / close on / off switch 33.

On the other hand, the person can stop the automatic opening and closing of the sliding door 102 by operating the on / off switch 33 in the off state.

According to the embodiment of the present invention as described above, by opening the transfer force to the swing door 102 in conjunction with the position of the lock 112, the swing door 102 is kept locked to the wall 101 In this state, it is possible to prevent the opening force from being transmitted to the sliding door 102.

And by installing the limit switch 31 in the housing 111 of the locking device 110 in place of the conventional proximity sensor for the purpose of opening control, the device structure is simplified.

In addition, by installing the outer proximity sensor (not shown) and the inner proximity sensor 32 on the outer surface and the inner surface of the wall 101, the casement door can be closed when the deviating from the safety distance to the swinging door 102. Will be.

In addition, by adding the opening and closing on-off switch 33, it can be stopped by the automatic opening and closing operation of the swing door 102 if necessary.

Meanwhile, in the above-described embodiment, the limit switch 31 is used as the position detection unit, but the present invention can be implemented to detect the position of the clamp 112 using an optical sensor (light emitting diode, light receiving diode, etc.). Of course.

Therefore, according to the present invention, the opening force is transmitted to the swing door by interlocking with the position of the lock, and the position detection part is installed in the housing of the lock for the purpose of opening control, so that the door is kept locked against the wall. The opening force can be prevented from being transmitted to the door and the device structure is simplified.
