When the train is not connected, the door panel 12 is in the closed position shown in FIG. 4A, and the panel body 33 is in a retracted position substantially parallel to the door panel 12 by the urging force of the urging member 39. When the door panel 12 is in the closed position, since the opening 22 is closed by the door panels 12 and 12, the passengers on the platform side cannot go out to the track side. At this time, it is considered that there is no possibility of unauthorized intrusion using the space S on the track side.

  Then, as the train arrives at the platform 16 and opens the side door, the door panel 12 opens along the track-side surface of the screen panel 11 and straightens to the open position shown in FIG. To open the opening 22.

  During the opening operation of the screen panel 12, the door bottom of the door panel 12 collides with the lever portion 37b. Accordingly, when the panel body 33 rotates toward the prevention position against the elastic force of the urging member 39 and the lever portion 37b is arranged along the door panel 12, the door bottom of the door panel 12 has the lever portion. 37b is pushed away and moved to the open position. Thereby, the panel body 33 becomes a prevention position, and the panel body 33 receives the elastic force of the urging member 39 and is held in a state where the lever portion 37 b is pressed against the side surface of the door panel 12. As a result, the space S on the line side of the screen panel 11 is blocked by the intrusion prevention fence 30, and even if there is a person who tries to make an unauthorized entry using this space S as an intrusion path, the intrusion prevention fence If 30 is arranged, the intrusion path is blocked, so that unauthorized intrusion can be prevented. In this prevention position, the vehicle B enters the platform 16, but the panel body 33 is configured in a shape that conforms to the side shape of the vehicle B. The problem of interference with B is unlikely to occur.

  That is, in the first embodiment, when the panel body 33 is in the retracted position, it is within the building limit A, but at the prevention position, it is installed so as to protrude from the building limit A. Can be blocked. As a result, the space S between the platform door device 10 and the platform end 16a is effective while ensuring safety even in the platform 16 in which the building limit A is set in the place retracted inward from the platform end 16a. Can be blocked.

  In the first embodiment, the lever portion 37b that rotates integrally with the panel body 33 is configured to enter the opening / closing track of the door panel 12. Therefore, the rotation operation linked to the opening operation of the door panel 12 can be easily performed. Can be realized. And since the bearing part 31 is fixed to the floor surface of the platform 16 and the header box 20, it can prevent that the load of the door panel 12 increases. Further, since the panel body 33 is urged toward the retracted position by the urging member 39, the panel body 33 can be prevented from fluttering due to the wind pressure when passing through the train. Further, since the lever portion 37b is arranged along the door panel 12 when the panel body 33 is in the prevention position, even if the panel body 33 in the prevention position tries to rotate in the retracted position direction by the biasing member 39, The lever portion 37b abuts on the door body to prevent the rotation operation. Thereby, it is possible to prevent the panel body 33 urged by the urging member 39 from returning to the retracted position.

  In the first embodiment, the rotation timing of the panel body 33 is determined by the position where the intrusion prevention fence 30 is disposed. Therefore, the rotation timing can be set by appropriately determining the installation position of the intrusion prevention fence 30. For this reason, it is possible to set the rotation timing according to the platform 16. In the first embodiment, the intrusion prevention fence 30 is arranged in the immediate vicinity of the opening 22 so that the panel body 33 is set to rotate to the prevention position as soon as the door panel 12 starts to open. Has been. For this reason, it is possible to effectively prevent unauthorized intrusion during the opening operation.

  The intrusion prevention fence 30 according to the second embodiment has a configuration in which the bearing portion 31 is provided on the door panel 12 and moves together with the door panel 12. The bearing portion 31 is provided on the vertical shaft 12 c on the door end side, and the upper bearing portion 31 a disposed at a position higher than the detection plate 26 and the lower bearing portion provided at a position lower than the detection plate 26. 31b. Since the detection plate 26 is fixed to the vertical rod 12c on the door end side, it is avoided that the detection plate 26 interferes by being divided into the upper bearing portion 31a and the lower bearing portion 31b. .

  The frame portion 34 is the same as that of the first embodiment in that it has a rotation shaft portion 34a and an overhang portion 34b. However, in the second embodiment, the rotation shaft portion 34a is an upper shaft above the detection plate 26. It is divided into a part 34 c and a lower shaft part 34 d below the detection plate 26. The flat plate portion 35 is provided with a cutout portion 35 a corresponding to the detection plate 26. The cutout portion 35a is set to have a shape and size through which the detection plate 26 can pass, and does not interfere with the detection plate 26 when the panel body 33 rotates.

  The projecting portion 34b of the frame portion 34 is provided with a protruding guide portion 41 that protrudes downward from the lower end portion thereof. The guide portion 41 is disposed at a position that does not protrude from the platform 16 when the panel body 33 is at the prevention position, and protrudes downward from the floor surface of the platform 16.

  As shown in FIGS. 7A and 7B, a guide groove 43 as an example of guide means is provided on the floor surface of the platform 16. The guide groove 43 is provided on the track side with respect to the opening / closing track of the door panel 12, and the guide portion 41 is inserted therein. That is, the guide part 41 moves along the guide groove 43 when the door panel 12 is opened and closed.

  The guide groove 43 includes a straight portion 43a extending in a direction parallel to the opening / closing track of the door panel 12, and a curved portion 43b continuous to the end of the straight portion 43a. The straight line portion 43a is formed corresponding to the position of the guide portion 41 when the panel body 33 is in the retracted position, and the curved portion 43b is operated so that the panel body 33 rotates between the retracted position and the prevention position. In addition, it is formed in the vicinity of the vertical direction of the screen panel 11. Thus, when the door panel 12 is opened, the panel body 33 is moved together with the door panel 12 while initially maintained in the retracted position, and is retracted in the vicinity of the screen panel 11 at the final stage of the opening operation. It rotates from the position to the prevention position.

  The intrusion prevention fence 30 is provided with a biasing member 39 and a stop plate 45. The biasing member 39 is made of, for example, a torsion coil spring, and biases the panel body 33 from the prevention position toward the retracted position. The stop plate 45 is fixed to the floor surface of the platform 16 and is disposed so as to be on the retreat position side of the panel body 33 in the prevention position. And the stop plate 45 is comprised so that the door panel 12 may be in an open position, and may contact | abut to the panel body 33 in a prevention position. Thereby, the panel body 33 in the prevention position is prevented from rotating to the retracted position by the biasing member 39.

  Here, the operation of the intrusion prevention fence 30 according to the second embodiment will be described. As shown in FIG. 7A, when the door panel 12 is in the closed position, the panel body 33 is in a retracted position that is substantially parallel to the door panel 12. Since the panel body 33 is urged by the urging member 39 even in this state, it is prevented from fluttering even when the train passes and receives wind pressure.

  And if a train enters and the door panel 12 opens, the guide part 41 will move along the linear part 43a of the guide groove 43 in connection with this. For this reason, the intrusion prevention fence 30 moves together with the door panel 12 in a state where the panel body 33 is maintained at the retracted position, and when the door panel 12 comes to the vicinity of the closed position, the guide portion 41 becomes the curved portion of the guide groove 43. It moves along 43b. Accordingly, when the panel body 33 is rotated from the retracted position to the preventing position and the door panel 12 is positioned at the closed position, the intrusion prevention fence 30 is projected from the platform end portion 16a to the track side. Thereby, the space S on the track side of the platform door device 10 is blocked.

  As described above, according to the second embodiment, even if there is a person who tries to enter using the space S on the track side of the platform door device as the entry path, the entry path is blocked by the panel body 33. Therefore, illegal intrusion can be prevented.

  Further, in the second embodiment, the panel body 33 is configured to rotate by moving the guide portion 41 of the panel body 33 along the guide groove 43 on the floor surface of the platform 16, so that the door panel 12 can be opened. The interlocking rotation operation can be realized easily and reliably. Further, by appropriately adjusting the shape of the guide groove 43, the rotation timing of the panel body 33 can be appropriately adjusted. Therefore, it is possible to set the rotation timing according to the platform 16.

  In the second embodiment, the intrusion prevention fence 30 is set to rotate only after the door panel 12 comes close to the closed position. However, the present invention is not limited to this, and for example, the door panel 12 is the same as in the first embodiment. The guide groove 43 may be set so that the intrusion prevention fence 30 rotates as soon as the opening operation is performed.

  Further, the guide groove 43 is not limited, and a convex guide rail slightly projecting from the floor surface of the platform 16 is provided, and the projecting portion 34b of the panel body 33 is guided so as to move along the guide rail. The part 41 may be formed in a concave shape.

  Further, the bearing portion 31 is not limited to the one composed of the upper bearing portion 31a and the lower bearing portion 31b. For example, when the detection plate 26 is not provided, one long bearing portion 31 is provided vertically. It is good also as a structure to be made.
