The opening / closing operation unit 13 is provided with handles 13h on both side surfaces of a rectangular parallelepiped (both sides of the surface on which the open button 13a and the close button 13b are provided). The opening / closing operation unit 13 is arranged at approximately waist height of the crew member C standing on the platform PH.

The movable support member 15 is a member that supports the opening / closing operation unit 13. The movable support member 15 has an arm 16 that can be bent and stretched (folded), a spring 17 that urges the arm 16 to be bent, and a lock mechanism 18 that temporarily fixes the arm 16 in a predetermined state. ing. The arm 16 includes a main arm 16a, a sub arm 16b, a connecting member 16c, a link 16d, and an end connecting member 16j.

In the present embodiment, the main arm 16a is composed of two rod-shaped members. In the main arm 16a, each rod-shaped member is formed to have the same length, and the total length of the two rod-shaped members is configured to be equal to or greater than the maximum horizontal movement distance of the opening / closing operation unit 13. In the present embodiment, the main arm 16a is made of hollow square cylindrical aluminum from the viewpoint of weight reduction. In the main arm 16a, one ends of each cylindrical member are connected to each other by a connecting member 16c. The main arm 16a is rotatably connected to the connecting member 16c. With this configuration, the main arm 16a is in a bent state in which the two cylindrical members are close to each other over the entire length of each, and each end on the opposite side to the connecting member 16c of the two cylindrical members. It is configured so that it can be bent and stretched between the stretched state and the distant stretched state. The end of the main arm 16a in which the two tubular members are connected by the connecting member 16c on the opposite side of the main arm 16a connected to the connecting member 16c of one of the tubular members is the end home via the end connecting member 16j. The opening / closing operation unit 13 is fixed in the vicinity of the operation panel 11 of the door pocket 8e and is connected to the connecting member 16c of the other cylindrical member, and the opening / closing operation unit 13 is provided at the end portion on the opposite side to the end portion via the end connecting member 16j. It is attached.

The auxiliary arm 16b is composed of two rod-shaped members. Each rod-shaped member of the sub-arm 16b is formed to have substantially the same length but a smaller thickness than each cylindrical member of the main arm 16a. One end of each of the thin rod-shaped members of the sub-arm 16b is connected to each of the cylindrical members of the main arm 16a by a connecting member 16c, and the other end is connected by an end connecting member 16j. The sub arm 16b is arranged along the main arm 16a. Adjacent members of the sub arm 16b and the main arm 16a are connected by a spring 17. As the spring 17, a tension spring is used. Since the spring 17 is provided, when the main arm 16a is extended, the spring 17 is stretched and an urging force that tries to bend the main arm 16a acts. In this way, the spring 17 acts to return the arm 16 to a bent state, that is, the opening / closing operation unit 13 to a position adjacent to the operation panel 11, and corresponds to a pulling member.

The link 16d is a member that limits the movable range of the main arm 16a so that the connecting member 16c, which is the lowermost part of the arm 16, does not touch the floor (platform PH). The link 16d is mainly attached to the main arm 16a. The lock mechanism 18, which is a component of the movable support member 15, is provided at the end of the end connecting member 16j and the main arm 16a in the vicinity of the opening / closing operation unit 13. The details of the configuration of the link 16d and the locking mechanism 18 will be described below.

3A and 3B are schematic views around the link 16d, FIG. 3A is a schematic front view, and FIG. 3B is a schematic rear view. The link 16d includes two flat bars 16df and a limiting plate 16dg. One ends of the two flat bars 16df are connected to each other by a limiting pin 16dp. The two flat bars 16df are configured so that the angle formed by the two flat bars 16df can be changed around the limiting pin 16dp. The end of each flat bar 16df on the side opposite to the side connected by the limiting pin 16dp is connected to each cylindrical member of the main arm 16a by a pin. The portion of each flat bar 16df connected to the main arm 16a is slightly separated from the connecting member 16c. The link 16d is configured such that the limiting pin 16dp is located at a higher position than the portion connected to the main arm 16a, and the cylindrical member of the main arm 16a and the flat bar 16df of the link 16d form a rhombus. Is arranged to form. The limiting plate 16 dl is a plate-shaped member formed in a substantially T shape, and is attached to the back surface (see FIG. 3 (B)). In the limiting plate 16dg, a portion extending from the center of the wide end portion extends upward, and the wide end portion is attached to the connecting member 16c. The wide end of the limiting plate 16dg is attached to the connecting member 16c at two points where the end of each cylindrical member of the main arm 16a is connected to the connecting member 16c, and moves and rotates with respect to the connecting member 16c. It is designed not to move. The height of the portion extending upward of the limiting plate 16dg extends upward beyond the limiting pin 16dp, and an elongated hole 16dh extending in the vertical direction is formed therein. On the back surface, the limiting pin 16 pd penetrates the elongated hole 16 dh and protrudes outward (extending in the direction perpendicular to the paper surface of FIG. 3 (B)). With such a configuration, the extent to which the main arm 16a extends is restricted to a range in which the limiting pin 16dp can move within the elongated hole 16dh, and when the main arm 16a tries to extend beyond the allowable range, the limiting pin 16dp is restricted. Is designed to hit the lower end of the elongated hole 16dh and restrict the main arm 16a from being opened any more. Further, when the arm 16 extends, the limiting pin 16dp moves along the elongated hole 16dh, so that the end connecting member 16j to which the opening / closing operation unit 13 is attached moves substantially horizontally. The end connecting member 16j to which the opening / closing operation unit 13 is attached is configured to move horizontally as the arm 16 opens / closes, but has an upward or downward component while having a horizontal component. It may also be configured to move.

FIG. 4A is a partial front view of the arm 16 showing the circumference of the lock mechanism 18. The lock mechanism 18 is provided around the end of the main arm 16a on the side to which the opening / closing operation portion 13 is attached. The lock mechanism 18 includes a lock groove 18g formed at one end of the main arm 16a and a lock piece 18h attached to the end connection member 16j. The lock groove 18g is generally formed in the shape of a circular arc centered on the connection portion of the tubular member in which the lock groove 18g is formed with the connecting member 16c. Further, as shown in FIG. 4B, the lock groove 18g is formed with a portion bent outward (the side farther from the connecting member 16c) at both ends thereof, and is formed on the other end of the main arm 16a. The portion bent outward on the side close to the tubular member is particularly referred to as "extended hook portion 18ge", and the portion bent outward on the side far from the other tubular member of the main arm 16a is particularly referred to as "curved hook portion 18gs". The arcuate portion between the extended hook portion 18ge and the curved hook portion 18gs is particularly referred to as a "main lock groove 18gm". The extended hook portion 18ge, the curved hook portion 18gs, and the main lock groove 18gm are each a part of the lock groove 18g. The lock piece 18h is attached to the end connecting member 16j at one support point 18f so that the upper surface 18ht covers the end connecting member 16j. In the present embodiment, the upper surface 18ht is approximately half the length of the lock piece 18h in a plan view. The upper surface 18ht is formed on the side far from the other tubular member of the main arm 16a. The support point 18f is provided at the end of the lock piece 18h on the side closer to the other tubular member of the main arm 16a. A spring (not shown) is provided between the upper surface 18ht of the lock piece 18h and the upper end of the end connecting member 16j, and the upper surface 18ht is separated from the end connecting member 16j by the spring (not shown) (FIG. 4). (A) is urged toward the upper side of the paper surface). When the upper surface 18ht is pushed toward the end connecting member 16j, the lock piece 18h rotates about the support point 18f so that the upper surface 18ht approaches the end connecting member 16j, and when the pushed external force is released, the lock piece 18h springs ( The upper surface 18ht is configured to be separated from the end connecting member 16j by (not shown). A lock pin 18hp is formed on the lock piece 18h at an end on the side farther from the other tubular member than the support point 18f and on the side opposite to the upper surface 18ht. The lock pin 18hp protrudes on the side opposite to the end connecting member 16j. The lock piece 18h is arranged at a position where the lock pin 18hp is fitted into the lock groove 18g.

A description of the entire movable support member 15 will be supplemented with reference to FIGS. 2 to 4. When the arm 16 of the movable support member 15 is in a bent state as shown in FIG. 2A, the lock pin 18hp of the lock mechanism 18 is located in the curved hook portion 18gs. The movable support member 15 removes the lock pin 18hp fitted to the curved hook portion 18gs from the curved hook portion 18gs, typically grasps the handle 13h of the opening / closing operation portion 13, and extends the arm 16 to extend the main arm. A force in the direction of closing the arm 16 acts on the spring 17 spanning the 16a and the sub-arm 16b, and the arm 16 is extended by overcoming the force of the spring 17, and the arm 16 is extended as shown in FIG. 2 (B). When the lock pin 18hp is extended, the lock pin 18hp is fitted into the extension hook portion 18ge. When the lock pin 18hp is fitted into the extension hook portion 18ge, the arm 16 is maintained (locked) in the extended state even if the hand is released from the handle 13h of the opening / closing operation portion 13. In order to bring the extended arm 16 into a bent state, the upper surface 18ht of the lock piece 18h is pushed so as to be close to the end connecting member 16j. Then, the lock pin 18hp reaches the arcuate portion of the main lock groove 18gm from the extended hook portion 18ge, and the arm 16 can be moved in the bent state. When the arm 16 moves toward a slightly bent state and the lock pin 18hp is separated from the extended hook portion 18ge, the arm 16 is moved by the force of the spring 17 even if the lock piece 18h and the opening / closing operation portion 13 are released. It can be folded in a bent state. In this way, the movable support member 15 is pulled back to the bent state when the external force for stretching the spring 17 is removed while the arm 16 is extended. The external force at this time corresponds to the force of the hand holding the opening / closing operation unit 13 or the locking mechanism 18 that keeps the arm 16 extended.

Subsequently, the operation of the platform door device 1 will be described with reference to FIGS. 1 to 4. Before the vehicle T enters the platform PH, all the home doors 6 are closed and the arm 16 of the movable support member 15 is in a bent state (see FIG. 2A). The vehicle T that has entered the platform PH stops at a predetermined stop position. Then, each vehicle door TD corresponds to the position of the home door 6. When the vehicle T stops at the platform PH, the crew room TC of the vehicle T may be located at a position away from the operation panel 11 and the opening / closing operation unit 13. In this case, the crew member C descends from the crew room TC, moves to the position of the opening / closing operation unit 13, grabs the handle 13h of the opening / closing operation unit 13, and pulls the opening / closing operation unit 13 to the vicinity of the crew room TC. When pulling the opening / closing operation unit 13, the upper surface 18ht of the lock piece 18h is pushed to move the lock pin 18hp contained in the curved hook portion 18gs to the main lock groove 18gm, and then the arm 16 is started to be extended. When the arm 16 extends and the lock pin 18hp enters the extended hook portion 18ge, the movable support member 15 is locked, and even if the crew member C releases his / her hand from the opening / closing operation unit 13, the arm 16 bends and the opening / closing operation unit 13 operates. It is possible to avoid returning to the side of the board 11.

When the arm 16 is extended and the lock mechanism 18 is locked, the opening / closing operation unit 13 is held in the vicinity of the crew room TC, and the crew C operates the home door 6 while checking the status of the platform PH. However, it becomes possible to operate the vehicle door TD. In this situation, the crew member C first presses the open button 13a of the open / close operation unit 13 to open the home door 6, and then operates the switch installed in the crew room TC to open the vehicle door TD. Then, the platform door 6 and the vehicle door TD that have blocked the platform PH and the inside of the vehicle T are retracted, and the passage W can pass through. As a result, passengers get on and off the vehicle T. When the crew member C confirms that the passengers have completed boarding / alighting, he / she first operates the switch installed in the crew room TC to close the vehicle door TD, and then presses the close button 13b of the open / close operation unit 13 to close the home door 6. do. Crew C can continue to monitor the vicinity of the home door 6 without moving from the crew room TC and the position near it from getting on and off by passengers until the home door 6 is closed, which is a burden on safety confirmation. Will be reduced and safety will be maintained.

After confirming the safe closure of the vehicle door TD and the home door 6, the crew member C pushes the upper surface 18ht of the lock piece 18h to move the lock pin 18hp contained in the extended hook portion 18ge to the main lock groove 18gm, and then the arm. Start bending 16. When the lock pin 18hp is disengaged from the extended hook portion 18ge, the arm 16 is bent by the action of the spring 17, and in this state, even if the crew member C releases his / her hand from the opening / closing operation unit 13, the opening / closing operation unit 13 is operated. Approaching board 11. When the arm 16 is in a completely bent state, the lock pin 18hp enters the curved hook portion 18gs, and the opening / closing operation portion 13 is maintained in the bent state of the arm 16. In this way, in order to return the opening / closing operation unit 13 to the side of the operation panel 11 (to keep the arm 16 bent), the crew member C needs to reciprocate between the crew room TC and the operation panel 11. Therefore, it is possible to reduce the need to keep an eye on the vicinity of the home door 6, and the safety is maintained. When the crew member C returns the opening / closing operation unit 13 to the side of the operation panel 11, the crew member C sends a departure signal to the driver. Upon receiving the departure signal, the driver departs the vehicle T from the platform PH.

As described above, according to the platform door device 1 according to the present embodiment, even when the operation panel 11 is provided at a place away from the crew room TC of the vehicle T stopped at the platform PH. The opening / closing operation unit 13 can be moved to the vicinity of the crew room TC to operate the platform door 6 and the vehicle door TD from within or near the crew room TC.

In the above description, the blocking member has been described as a home door 6 that opens and closes by moving in the horizontal direction, but may be a fence, a rope, or the like that opens and closes by moving vertically up and down.

In the above description, the operation panel 11 and the movable support member 15 to which the opening / closing operation unit 13 is attached are indirectly fixed to the platform PH by being fixed to the wall surface on the track R side of the terminal home door pocket 8e. However, it may be directly fixed to the platform PH.

In the above description, it is assumed that the conductor C who opens and closes the home door 6 (blocking member) via the operation panel 11 or the opening / closing operation unit 13 is the conductor, but typically the operation of the vehicle T and the vehicle door TD. In the one-man operation vehicle T that opens and closes by itself, the crew member C who opens and closes the blocking member may be the driver. In this case, the operation panel 11 and the opening / closing operation unit 13 are typically provided at the tip end (front end in the traveling direction) of the platform PH.
