  In the prior art home door, the slide door is heavy, and therefore, a support structure for supporting the slide door slidably with respect to the door pocket must be rigidly configured. Further, in the prior art home door, the sliding door extends upward from immediately near the upper surface of the platform, and is supported by the lower edge members 16d and 18d of the sliding door. In addition, the sliding door must have sufficient robustness against the moment due to the crowd load acting from the platform side to the track side. Thus, prior art home doors are heavier and larger, which increases manufacturing costs.

  In addition, by installing the platform door on the platform, it is possible to reduce the labor of station staff located on the platform to check the safety of trains as well as to prevent people from falling out. However, since the platform is installed on the platform, there is a problem that the track side cannot be seen from the platform side. In particular, there is a problem that even if a person is hiding or an object is placed behind the door pocket of the home door, it becomes blind spot and cannot be seen from the platform side.

  An object of the present invention is to solve such a problem of the related art, and an object of the present invention is to provide a home door device having a small blind spot and a reduced manufacturing cost and installation work cost.

The present invention according to claim 1, wherein the platform is arranged along an edge of the platform, wherein the platform is fixed to an upper surface of the platform, a door pocket attached to the platform, and the platform includes: A sliding door provided so as to be able to advance and retreat with respect to the door pocket in a direction along the edge of
A gist of the present invention is that the slide door is formed in a substantially U-shape with an end on the side of the door open.

An upper portion of the door pocket is cut off at both ends, and the sliding door can be configured such that a door portion is exposed when stored in the door pocket.
The slide door includes a lower edge member, and an upper member formed of an L-shaped bent bar member connected to the door end side of the lower edge member and extending toward the door butt side. It can be extended to the side of the door so that a space is formed between the lower edge member and the upper member.

  By forming the slide door in a substantially U-shape with the end on the side of the door open, the weight of the slide door is reduced, so that the support and guide structure of the slide door can be simplified, and the manufacturing cost of the home door device is reduced. Reduced. Furthermore, by forming the slide door in a substantially U-shape, the blind spot when viewed from the platform side is reduced.

  Furthermore, by forming the sliding door in a U-shape, the wind load (horizontal load when the wind hits the sliding door) is smaller than that of the conventional sliding door (the door is formed by a panel-shaped member). In this case, the cost of the installation work of the home door can be reduced by eliminating (or reducing) the work of reinforcing the foundation, especially in the platform of the embankment structure.

  In a region above the upper plate 340 in the side plate 332 of the first movable door pocket 330, two round holes 334a and 334b are provided in the region above the upper plate 340 so that the upper members 306a and 308a of the sliding doors 306 and 308 can pass therethrough. Is formed. Similarly, in the area below the side plate 332 of the first movable door pocket 330, two square holes 336a, as in the stationary door pocket 320, so that the lower edge members 306d, 308d of the sliding doors 306, 308 can pass through. 336b is formed.

  The door ends of the upper members 306a and 308a of the sliding doors 306 and 308 are supported by the round holes of the side plate 371 and the round holes 324a and 324b of the side plate 332.

  The first movable door pocket 330 is different from the second movable door pocket 360 in further including a telescopic part. The extendable portion makes the length of the first movable door pocket 330, that is, the turning radius from the hinge 328 variable, and can take a forward position where the width becomes maximum and a retracted position where the width becomes minimum.

  The elastic portion includes an upper elastic portion 350, a front lower elastic portion 352, a rear lower elastic portion 354, and a connecting portion 356 that connects the upper elastic portion 350 and the rear lower elastic portion 354. The upper elastic portion 350 has a cross-sectional shape substantially similar to the cross-sectional shape of the upper cover 321 so that it can be inserted into a space defined by the upper cover 321 and the upper plate 340. The front lower elastic portion 352 and the rear lower elastic portion 354 are formed so as to be insertable into a space defined by the lower cover 323 and the bottom plate 342. The upper extensible portion 350 has a band-shaped upper slider portion 350a extending in the X direction. The upper slider portion 350a is inserted into slits provided in two guide plates 351 provided in the upper plate 340. You will be guided to move in the X direction.

  The front lower elastic portion 352 and the rear lower elastic portion 354 are formed symmetrically about the partition plate 344, and are connected by a connecting portion (not shown). The front lower elastic portion 352 includes a front end portion 352a that forms a vertically long rectangular hole through which the lower edge members 306d and 308d of the slide doors 306 and 308 can penetrate, and a substantially U-shape extending from the front end portion 352a to the side plate 332 side. And a lower slider portion 352b. The rear lower elastic portion 354 is formed similarly to the front lower elastic portion 352. The upper telescopic portion 350, the front lower telescopic portion 352, and the rear lower telescopic portion 354 are integrated, and are movably supported in the sliding direction of the slide doors 306, 308. The entire telescopic portion can be moved in the sliding direction of the sliding doors 306 and 308. In FIGS. 32, 34, and 36, the telescopic portion is disposed at the forward position.

  The telescopic part is usually arranged at the forward position, but when opening the closed first and second movable door pockets 330, 360, it may be moved to the retracted position. Thereby, it becomes possible to avoid interference between the tip portions of the first and second movable door pockets and to rotate the door pockets. When closing the first and second movable door pockets 330 and 360, the first and second movable door pockets 330 and 360 are closed in a state where the expansion and contraction section is in the retracted position, and then the expansion and contraction section is moved to the forward position. Just do it. This makes it possible to fill the gap between the first and second movable door pockets.

In particular, the upper members 306a and 308b pass directly below the upper covers 321 and 368 of the movable door pockets. For this reason, if there is a gap between the two upper covers 321 and 368 where the finger of the passenger can enter, it is very dangerous. However, according to the present embodiment, the effect of the expansion and contraction portion of the first movable door pocket 330 is normal. Thus, such a gap for a finger or the like does not occur. On the other hand, in an emergency or the like, the first and second movable door pockets 330 and 360 can be rotated while avoiding mutual interference by providing the gap by retracting the expandable portion.

  Further, the expansion and contraction portion of the first movable door pocket 330 makes it possible to set a large permissible error in the installation position of the sliding doors 306 and 308 in the sliding direction, particularly during installation work. Therefore, according to the home door unit 300 of the present embodiment, it is expected that the installation work is facilitated and the work time is shortened.

  In the above-described embodiment, one of the pair of movable door pockets has the first movable door pocket 330 having the elastic part. However, an embodiment in which both the pair of movable door pockets have the elastic part is also possible.

  In the present embodiment, the home door unit 300 is also provided with the closing stop unit as described in the above-described embodiment in order to limit the stroke of the slide doors 306 and 308 between the closed position and the open position. (Not shown), an opening limit stop (not shown), and a closing contact member (not shown) and an opening contact member (not shown) attached to the slide doors 306 and 308. I have. Further, the home door unit 300 includes a closing sensor and an opening sensor that detect that the sliding doors 306 and 308 are in the open position and the closed position, and the sliding door 306 and 308 reach the open position or the closed position. At times, power supply to the drive motor of the drive is automatically shut off.

  Also in the present embodiment, the train stops for some reason at a position where the vehicle door and the opening S of the home door unit 300 do not face each other (a position where they are shifted), and then the train moves due to a power failure or other reasons. When the state is not present, it is possible to manually open the movable door pockets 330 and 360 and to move passengers in the train to the platform P with the emergency door between the pair of stationary door pockets 320 of the home door unit 300. Become.
