A closed passive body 3 and an open passive body 4 located in the opening direction of the closed passive body 3 are attached to a sliding door 2 that opens and closes linearly in a frame 1. A driving projection 6 of a mover 5 such as a linear motor that opens and closes the sliding door 2 is positioned between the closed passive body 3 and the open passive body 4, and when the sliding door 2 is closed, the driving projection 6 and the closed passive body 3 are separated from each other. At the same time, the gap X is maintained between the driving projection 6 and the open passive body 4. A rail 7 and a door roller 8 are used to open and close the sliding door 2 linearly in the frame 1.

No. 429 is known, and in order to seal the sliding door 2 in the frame 1 in the door closed state, a sealing device 9 having a finite door closing force by a rotary permanent magnet is used. The door closing force is, for example, about 600 N, and the distance over which the action of the door closing force reaches is determined by the magnitude of the magnetic force. In addition, a spring (not shown) is arranged between the opening passive body 4 and the driving projection 6 to make the opening operation smooth. The sealing device 9 may be a conventional mechanical type in which a fixed non-rotating permanent magnet, electromagnet or elastic female can be fitted in the opening and closing direction.

状態は維持される。According to the prior art, when the driving projection 6 of the prime mover such as a linear motor moves in the opening direction from the door closed state, the gap X is reduced and the driving projection 6 is opened. The sliding door 2 is opened via 4. When the driving projection 6 moves in the closing direction while the sliding door 2 is open, a gap X is created and the driving projection 6 closes the sliding door 2 via the closed passive body 3. Even if the driving force of the prime mover is shut off, the closed state of the sliding door 2 is maintained by the sealing device 9.

The sliding door 2 opens together with the mover 5 as one. In the case of a train, if the sliding door 2 is pry open during traveling, a serious accident such as a fall may occur. Further, if it is possible to open the door, the finger pinched by the door can be pulled open by pulling out the sliding door 2, so that it is not necessary to repeat the door closing operation for removing the finger or the like while the vehicle is stopped, and the departure time can be delayed. Absent. However, on the other hand, some of the passengers rush to open the sliding door 2, which is almost closed, and try to get in, so the departure time is delayed and the operation of the train is hindered. It is a waste of electric power to keep the driving force of the linear motor closed while the vehicle is running.

There is a state A in which the gap Y of the stopper does not change. During this state A, the sliding door can be fully opened because the protrusion of the prime mover moves one of the stoppers which can be moved in and out in the "in" direction to release the engagement with the other. If only the sliding door is to be pry open, the sliding door moves the prime mover via the connecting means so that the gap X does not change, but the sliding door moves to reduce the gap Y between both stoppers, and the state A does not exist. Therefore, the gap Y becomes zero before the projection disengages the stoppers, and the sliding door cannot be opened beyond the gap Y.

A mechanical stopper 10 is formed from the sliding door-side stopper 11 fixed to the sliding door 2, the fixed-side stopper 12 engaged with the sliding door 2, and attached to the frame 1, and the cam device 13. The cam device 13 is formed with the projection 14 provided on the fixed-side stopper 12 as a follower, with the driving projection 6 as an original. A roller 14a may be attached to the projection 14. A compression spring 12b is provided on a slide bolt 12a that allows the fixed stopper 12 to move in and out in a direction perpendicular to the opening and closing direction of the sliding door 2, so that "out" is performed.
In the direction (toward the sliding door side stopper 11). The slide bolt 12a is slidable to a metal fitting 12c fixed to the frame 1 or the like so that the slide bolt 12a can be moved in and out so that there is no play other than in and out of the direction. In the door-closed state, the sliding door-side stopper 11 is positioned opposite to the fixed-side stopper 12 in the door-closing direction with a gap Y to be engageable. Further, the gap Y is set within a distance over which the finite door closing force of the sealing device 9 can reach.

用できる。The fixed stopper 12 is turned on via the cam device 13 by the movement Z of the drive projection 6 in the opening direction within the gap X.
To release the engagement with the sliding door side stopper 11,
After the sliding door side stopper 11 is located in the opening direction of the fixed side stopper 12, it is returned to the "out" direction. The relationship between the movement Z and the “in” and “out” is determined by the shape of the cam device 13 and the shape of the follower and follower (two-dimensional shape in the opening / closing direction and the direction perpendicular thereto). It is decided as a matter. That is, the shape is determined by the shapes of the driving projections 6 and the projections 14 including the rollers 14a. To bias the fixed-side stopper 12, a magnetic force or gravity can be used instead of the compression spring 12b.

As the intermediate state between the door closed state in FIG. 1 and the state shown in FIG. 3, the movable door 5 is driven in the opening direction, the driving projection 6 moves in the opening direction, the gap X starts to shrink, and the sliding door approaches 0. There is a state A in which the gap Y between both stoppers 11 and 12 does not change while 2 is still closed. During this state A, the movement Z of the drive projection 6 causes
The drive projection 6 serves as an original section of the cam device 13, and is fixed via a convex section 14 including a roller 14 a as a follower.
In the “in” direction to release the engagement with the sliding door side stopper 11. When the engagement is released, the sliding door 2 can be fully opened by the driving projection 6. When the driving projection 6 moves in the opening direction of the projection 14, the sliding door side stopper 11
2, the fixed-side stopper 12 returns to the “out” direction.

State A described above does not exist. Therefore, the gap Y becomes zero before the drive projection 6 releases the engagement between the stoppers 11 and 12, and the sliding door 2 cannot be opened beyond the gap Y. When a finger or the like is pinched by closing the door, the sliding door 2 is provided for the gap Y.
When the gap Y is set within a range where the action of the door closing force of the sealing device 9 can reach, the opened sliding door 2 is automatically returned by the sealing device 9 to open the door. It can return to the closed state. If the gap Y is small and the elastic packing (not shown) at the edge of the sliding door 2 can absorb the gap Y, the sealing device 9 may be omitted.

The stopper 12 is moved in the “in” direction to release the engagement with the sliding door side stopper 11. After the sliding door side stopper 11 is positioned in the closing direction from the fixed side stopper 12 while releasing, the sliding door side stopper 11 engages with the fixed side stopper 12 and returns to the door closed state.

節であり、レバー３２ａは従節である。In FIG. 6, a passive body 35 is mounted on a sliding door 2 which opens and closes linearly in a frame 1. The closing drive projection 33 and the opening drive projection 34 of the mover 5 of the linear motor that opens and closes the sliding door 2
And the passive body 35 is located between them. In the door-closed state, the closing drive projection 33 and the passive body 35 come into contact with each other and the open drive projection 3
A gap X is kept between the target 4 and the passive body 35. The fixed-side stopper 31 is fixed to the frame 1. A sliding door-side stopper 32 engageable with the sliding door 2 is attached to the sliding door 2 via a lever 32a.
In 2b, it is urged in the “out” direction (toward the fixed-side stopper 31). The sliding door side stopper 32 is positioned in the door closing direction with a gap Y with respect to the fixed side stopper 31. The protrusion 36 attached to the mover 5 moves the sliding door side stopper 32 in the “in” direction by the movement Z in the opening direction within the range of the gap X to release the engagement with the fixed side stopper 31. The projection 36 is the original section of the cam device, and the lever 32a is the follower.
