A roller 11 is rotatably attached to the other end of the closing member 17 . A spring 18 is bridged between the closing member 17 and the door pocket 3 to bias the closing member 17 toward the door 5 . Therefore, the closing member 17 is biased by the spring 18 toward the door 5 . As a result, the roller 11 contacts the side surface of the door 5 . That is, the other end of the closing member 17 contacts the side surface of the door 5 .

The spring 18 is an example of an elastic member that biases the closing member 17 in the direction in which the tip of the closing member 17 approaches the door 5 . Further, since the platform door device 1 is provided with the spring 18, even if the door body 5 is laterally swaying with respect to the door pocket 3, the blocking member 17 is prevented from moving between the edge of the door entrance 7 and the door body 5 on the platform side. The gap between is maintained. In this way, the spring 18 maintains the state where the closing member 17 covers the gap between the edge of the door entrance 7 and the door body 5 even when the door body 5 laterally swings with respect to the door pocket 3. It functions as a lateral shake tracking means. Therefore, even if the door body 5 is laterally swaying with respect to the door pocket 3, the careless insertion of fingers by the passenger is prevented. As a result, the level of mounting accuracy of the door 5 to the door pocket 3, which is required in the manufacturing process of the platform door device 1, is relaxed.

As shown in FIG. 8(A), the closing member 17 may be attached to the door pocket 3 via a rotating hinge 19 with a spring. In the example shown in FIG. 8A, the spring-loaded rotary hinge 19 acts as a rotary spring to rotate the closure member 17 in the direction indicated by the arrow. That is, the spring-equipped rotating hinge 19 acts as a rotating spring that rotates the closing member 17 clockwise around the spring-equipped rotating hinge 19 , so that the end of the closing member 17 contacts the side surface of the door 5 . Therefore, in the platform door device 1 , even if the door 5 is laterally swaying with respect to the door pocket 3 , the end portion of the blocking member 17 is kept in contact with the door 5 . In this way, the spring-loaded rotating hinge 19 causes the closing member 17 to follow the lateral swing of the door 5, and maintains the state in which the closing member 17 covers the gap between the edge of the door entrance 7 and the door 5. It functions as a lateral shake follow-up means.

The lateral vibration follow-up means for causing the closing member 17 to follow the lateral vibration of the door 5 is not limited to the spring 18 and the spring-equipped rotating hinge 19 . The elastic force of the closing member 17 itself may allow the closing member 17 to follow the lateral vibration of the door 5 . In other words, the closing member 17 itself may function as a lateral vibration follower.

For example, as shown in FIG. 8(B), a closing member 17 having a "<" shape in cross section may be made of a rubber material. One end of the closing member 17 is fixed to the door pocket 3, and the closing member 17 is pressurized so that the closing member 17 is deformed in the direction indicated by the arrow in FIG. When applied, the other end of the closing member 17 is displaced following the lateral vibration of the door member 5 . As a result, even if the door body 5 is laterally swaying with respect to the door pocket 3, the gap between the edge of the door entrance 7 and the door body 5 is covered with the closing member 17. A finger can be prevented from being inserted into a gap between the edge of 7 and the door body 5.例文帳に追加

Further, as shown in FIG. 8(C), a contact sensor 20 for detecting contact with a foreign object may be attached to the outer surface of the closing member 17, that is, the surface exposed to the outside of the door pocket 3. FIG. The safety of the platform door device 1 can be improved by performing control to stop the platform door device 1 when a passenger's finger touches the contact sensor 20 in a control device (not shown) provided in the platform door device 1 .

Note that the specific configuration and detection principle of the contact sensor 20 are not limited. A strain gauge, an electrostatic sensor, a sensor utilizing the piezoelectric effect of polyvinylidene fluoride, or the like can be used as the contact sensor 20 .

In the example shown in FIG. 8(C), the spring-equipped rotating hinge 19 acts as a rotating spring that rotates the closing member 17 in the direction indicated by the arrow. That is, the spring-loaded rotary hinge 19 acts as a rotary spring that causes the closure member 17 to rotate clockwise around the spring-loaded rotary hinge 19 . Therefore, the tip of the blocking member 17 contacts the side surface of the door 5 .

(Fifth embodiment)
FIG. 9(A) is a view of the platform door device 1 according to the fifth embodiment of the present invention as seen from the doorway side. FIG. 9(B) is a cross-sectional view of the platform door device 1 taken along a plane indicated by line CC' in FIG. 9(A).

A collar 26 is fitted between the bolt 22 and the door pocket 3 . The height of the collar 26 is slightly greater than the sum of the thicknesses of the washer 24, the cover member 21 and the plate 25. 9(B), the gap between the bolt 22 and the door pocket 3 is equal to the height of the collar 26. As shown in FIG. Therefore, the cover member 21 is not fixed to the door pocket 3 because the thrust of the bolt 22 is not applied to the cover member 21 . Since the major axis of the slot 23 extends in the home-track direction, the cover member 21 can freely move in the home-track direction.

In this way, the cover member 21 can freely move in the home-track direction, so when the door body 5 laterally swings with respect to the door pocket 3, the cover member 21 is pushed by the door body 5 and moves in the lateral direction. Therefore, even if the door body 5 is laterally swaying with respect to the door pocket 3, the gap between the door body 5 and the edge of the door entrance 7 is always closed, so that the passenger carelessly closes the door entrance 7. A finger can be prevented from being inserted into the gap between the edge and the door body 5.例文帳に追加As a result, the level of mounting accuracy of the door 5 to the door pocket 3, which is required in the manufacturing process of the platform door device 1, is relaxed.

As described above, in the platform door apparatus 1 according to each of the above-described embodiments and modifications, even if the door 5 is laterally swaying with respect to the door pocket 3, the passenger carelessly opens the door entrance 7. A state in which fingers are prevented from being inserted into the gap between the edge of the door and the door body 5 is maintained. Further, even if the door body 5 is laterally swaying with respect to the door pocket 3, there is no problem in moving the door body 5 forward and backward with respect to the door pocket 3. - 特許庁Therefore, the level of accuracy with which the door 5 is attached to the door pocket 3 in the manufacturing process of the platform door device 1 is relaxed. As a result, the platform door device 1 can be easily manufactured, and the manufacturing cost of the platform door device 1 can be reduced.
