[9] At least the first drive mechanism 220 and the second drive mechanism 320 are disposed on the side opposite to the track side with respect to the first door body 200 and the second door body 300. The door apparatus according to [8].

The present invention operates as follows.

Since the first connecting portion 210, which receives the force for the forward and backward movement from the first drive mechanism 220, protrudes from the part of the rear end of the first door body 200 in the advancing direction when immersed, the first Most of the door body 200 can be made to exit the door storing unit 111. The same applies to the second door body 300.

Further, the first door body 200 and the second door part are provided with the protruding position from the first door body 200 of the first connecting part 210 and the protruding position from the second door body 300 of the second connecting part 310. The movement trajectory of the first connecting portion 210 and the movement trajectory of the second connecting portion 310 formed when the door body 300 moves forward and backward are set so as to be parallel to each other in the same plane. As a result, no matter how deeply the first door body 200 and the second door body 300 are accommodated in the door storage 111, the first connection part 210 and the second connection part 310 collide with each other. There is no work.

That is, the stop position of the 1st door body 200 and the 2nd door body 300 when it is stored in the door storing part 111 is the front-end | tip of the 1st connection part 210 in this stop position. It can set to the position which advanced to the rear end side of the 2nd door body 300 rather than the front end of 310.

For example, when the first connecting portion 210, the second connecting portion 310, the first door body 200, and the second door body 300 are located in the same plane, the tip of the first connecting portion 210 is located. And the rear end of the second door body 300 or the front end of the second connection part 310 and the rear end of the first door body 200 may be brought close to each other to be stored in the door storage part 111. . Thereby, since the total length of the door storing part 111 can be shortened, the opening width can be enlarged by that much.

In addition, when the first connecting portion 210 and the second connecting portion 310 are present in a plane different from the plane in which the first door body 200 and the second door body 300 exist, the doors are housed in each door body. No matter how deeply the 111 is stored, the first connecting portion 210 and the second door body 300 do not contact each other, or the second connecting portion 310 and the first door body 200 do not contact each other. For this reason, since these door bodies can be stored to the depth of the door storage part 111 until just before the rear ends of the 1st door body 200 and the 2nd door body 300 contact, the opening width is further increased. Can catch big.

Further, since the first connecting portion 210 and the second connecting portion 310 are in the same plane, the door storing portion 111 can be made thinner than when the connecting portion is in another plane. For example, when the first connecting portion 210 and the second connecting portion 310 are arranged side by side on the surface side of the first door body 200, the first driving mechanism 220 and the second driving mechanism 320 are arranged. Both sides of the first door body 200 is disposed on one side of the side. Accordingly, the door is compared with the case where the first connecting portion 210, the first driving mechanism 220, the second connecting portion 310, and the second driving mechanism 320 are divided into the front side and the rear side of the door body. The storage part 111 can be made thin.

As the first drive mechanism 220, the first fixing parts 221 and 223 fixed to the door storage part 111 side, the first moving part 225, and the first moving part 225 are arranged in a first height. What is necessary is just to use what has the 1st moving mechanism 222,225 which linearly moves relative to the government parts 221,223, and the 1st drive part 224 which produces the driving force for relative movement. Similarly, as the second drive mechanism 320, the second fixing parts 321 and 323 fixed to the door storage part 111 side, the second moving part 325, and the second moving part 325 are provided in the second height. The second moving mechanisms 322 and 325 to which the opponent moves linearly with respect to the front parts 321 and 323, and the second drive part 324 which generate | occur | produces the driving force for relative movement are used.

For example, the moving mechanism may be an endless belt, the endless belt may be rotated by a drive unit, and the moving unit may be attached to a predetermined portion of the belt. The screw transfer mechanism may also move the moving part forward and backward. That is, the ball screws 222 and 322 supported by the fixing part are installed in succession at least in a range in which the corresponding connection part of the door body should be moved forward and backward, and the nut members 225 and 325 screwed to the ball screws 222 and 322. Thereby constitutes a moving mechanism. One of the ball screws 222 and 322 and the nut members 225 and 325 is rotatably supported by the other so as to be rotatable, and the rotatable one of the balls is rotated by the driving unit to move the moving unit together with the nut unit. It is configured to move forward and backward.

On the other hand, the door device is installed along the side edge on the platform 10, is suitable for the movable platform handrail device 100 for partitioning the track side and the platform 10 side through which the train passes. In this case, at least the first drive mechanism 220 and the second drive mechanism 320 are opposite to the track side with respect to the first door body 200 and the second door body 300, that is, the inside of the platform 10. In the vicinity of the railing, the installation and maintenance of the device can be performed from the inner side of the railing (opposite side of the rail), thereby increasing the safety of the work.
