DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS.
An embodiment of the present invention will be described. First, FIG. 1 shows the installation configuration of the open / close fence, (A) is a front view of the open / close fence,
(B) It is the right view. In FIG. 1, an opening / closing fence 1 comprises a screen-shaped door pocket 2 and a sliding door type door 3 which is housed in the door pocket 2 so as to be able to enter and exit in the direction of the arrow in FIG. 1A. For example, a slide rail attached to the door pocket side and a slide bearing attached to the door side and sliding on the slide rail are slidably supported in the door pocket 2, and the slide bearing is driven by a motor (not shown). Thus, the door pocket 2 can be moved in and out.

[0006] Here, the door pocket 2 is connected to the platform 4 in a direction parallel to the entrance / exit direction of the door 3 and in the direction in which the door 3 is pulled out (Fig. 1).
(To the right) of the camera. The configuration for this is as follows. First, a groove 5 having a fixed length is formed on the floor surface of the platform 4 along the moving direction of the door pocket 2, and a slide rail 6 is fixed inside the groove. The fixing of the slide rail 6 is performed by screwing bolts through the slide rail 6 into nuts (not shown) embedded in the floor at several points in the longitudinal direction.

On the other hand, a slide bearing 7 which is in contact with the upper surface of the slide rail 6 so as to cover the upper surface of the slide rail 6 is fixed to the left end of the bottom of the door pocket 2 in FIG. A door roller 8 is mounted via a rolling bearing (not shown). The slide bearing 7 is a known one having a number of balls circulating infinitely, and slides on the slide rail 6 while making rolling contact via the balls.

In FIG. 1, the door pocket 2 is at a fixed position before moving, and is positioned and fixed by a lock mechanism 9.
The lock mechanism 9 locks the door pocket 2 at the illustrated position by inserting a lock rod 9b guided and held by the door pocket 2 vertically up and down by the cylindrical guide fitting 9a into a hole (not shown) of the slide rail 6. When the lock bar 9b is pulled up with the handle 9c, the lock of the door pocket 2 is released. Door 3
Power is supplied via a flexible conductor 10 to a drive motor (not shown) in the door pocket 2 for driving the motor.

In the above-mentioned opening / closing fence 1, the door 3 moves in and out of the door pocket 2 by driving a motor. Further, the door pocket 2 having one end slidably supported on the slide rail 6 via the slide bearing 7 and the other end slidably supported on the platform floor via the door roller 8 is released by releasing the lock mechanism 9. The slide bearing 7 is manually moved until it comes into contact with the right end of the groove 5 in FIG. The door pocket 2 after the movement is fixed at that position by inserting the lock bar 9b into the hole 6a at the right end of the slide rail 6.

FIG. 2 is a view for explaining the open / close state of the open / close fence 1. A fixed safety fence 11 is installed on both sides of the open / close fence 1. In FIG. 2A, the open / close fence 1 is at the normal position, and the door 3 faces the entrance door 13 of the train 12 stopped at the regular position. FIG. 2 (B) shows a state in which the door 3 of FIG. 2 (A) is opened, and in this state, smooth entry / exit with respect to the entrance / exit door 13 at the normal position is performed. However, when the door 13 is shifted to the position shown by the chain line in FIG.
When the train 2 stops, the gap between the train 12 and the fence 1 is originally narrow, so that it is difficult to pass through the fence 1. In that case, as shown in FIG. 2C, the door 3 is pulled in and the door pocket 2 is moved rightward. Thereby, even when the train stop position shifts, a sufficient passage for the entrance door 13 can be secured.

In FIG. 2, the open / close fence 1 is located between the left and right safety fences 11.
FIG. 3 shows an example in which two opening / closing fences 1 in which doors 3 enter and exit independently of each other are installed such that the doors 3 face each other. Thereby, the correction of the passage position can be performed more widely. As shown by the arrow in FIG.
The door pocket 2 can also be installed so as to be movable in the direction in which the door 3 is pulled in. In this case, the front and rear positions of the safety fence 11 are shifted so that the door pocket 2 does not hit when moving. The two opening / closing fences 1 can be installed so that the door pockets 2 face each other, and the door pocket 2 can also be installed so as to be movable in both directions of the pulling-out direction and the pulling-in direction of the door 3. . In the above-described embodiment, an example in which a slide bearing and a door wheel are used together as a door pocket moving mechanism has been described. However, the configuration is free, such as using only a slide bearing or only a door wheel, and is not limited to the illustrated configuration. .

[0012]

As described above, according to the present invention, the passage of the opening / closing fence can be easily changed by moving the door pocket, and the movement is performed in parallel with the platform. There is no hindrance, and the mechanism and operation for movement are simplified.
