When the positive polarity is given to the driving motor 110 in the state of FIG. 8, the driving pulley 120 is rotated in the forward direction (direction for the opening operation of the sliding door 1).

The forward rotation of the driving pulley 120 causes the wire 140 to rotate in the clockwise direction of FIG. 3, and thus the sliding bar 210 is moved to the left side of FIG. 3.

Therefore, as shown in FIG. 8, the sliding bar 210 and the sliding door 1 move to the left side.

The sliding door 1 moves to the left and then the first stopper 5 (the first stopper 5 does not interfere with the sliding bar 210 on the movement path of the sliding door 1, but does interfere with the sliding door 1). The sliding bar 210 continues to go straight, but the sliding door 1 does not go straight by the first stopper (5).

That is, the guide pin 320 fixed to the sliding door 1 moves along the curved guide part 310 to compensate for the straightness of the sliding bar 210. This is shown in Figure 9, the guide pin 320 is moved to the second blocking portion 312 of the curved guide portion 310 and eventually the sliding door (1) to the position to avoid the first stopper (5) Will move.

The sliding bar 210 continues to go straight, and the sliding door 1 moves with the sliding bar 210 to overlap the rear of the fixed door 2, whereby the passage W is opened (FIG. 10 and FIG. 11).

3. Aisle closing operation.

2. When the negative polarity is applied to the driving motor 110 to close the passage W in a state in which the passage W is closed through the passage opening operation, the driving pulley 120 rotates in reverse (refer to FIG. 11). Direction).

The reverse rotation of the driving pulley 120 causes the wire 140 to rotate counterclockwise with reference to FIG. 11, and thus the sliding bar 210 moves to the right with reference to FIG. 11.

Thus, as shown in FIG. 12, the sliding bar 210 and the sliding door 1 move to the right. At this time, the sliding door 1 maintains the alignment state arranged behind the fixed door 2.

The sliding door 1 moves to the right together with the sliding bar 120, but the second stopper 6 (the second stopper 6 does not interfere with the sliding bar 210 on the movement path of the sliding door 1). The sliding bar 210 continues to go straight, but the sliding door 1 cannot go straight by the second stopper 6 when it hits the sliding door 1).

That is, the guide pin 320 fixed to the sliding door 1 moves along the curved guide part 310 to compensate for the straightness of the sliding bar 210.

Therefore, in the state of FIG. 12, as in the state of FIG. 8, the guide pin 320 moves to the first blocking portion 311 of the curved guide portion 310, and as a result, the sliding door 1 has a second stopper ( 5), i.e., move to the side passage W of the fixed door 2, whereby the passage W is closed (see FIGS. 3 and 8).

13 to 15 show the operation of the lower opening and closing rod 400, the free end of the lower opening and closing rod 400 in the state in which the sliding door 1 is opened is disposed at the inlet side of the sliding groove (1a). It is.

When the sliding door 1 closes and reaches the position of FIG. 12, the free end of the lower opening / closing rod 400 is caught by the locking portion 1b of the sliding groove 1a as shown in FIG. 14, and the sliding door ( When 1) is changed from the state of FIG. 12 to the state of FIG. 8, the free end of the lower opening / closing rod 400 rotates along the locking portion 1b (see FIG. 15). As such, the elastic member 410 is elastically deformed by the rotation of the lower opening / closing oil dowel 400 to support the lower opening and closing rod 400 to return to the position of FIG. 13.

On the other hand, when the sliding door 1 is opened in order to open the passage W in the state of FIG. 15, the sliding door 1 is elastic because a force in a direction assisting the restoring force of the elastic member 410 is applied. Since the lower opening and closing rod 400 pushes the sliding door 1 to the open position through the restoring force of the member 410, the opening of the sliding door 1 is more smoothly performed.
