It moves horizontally between the restricted position that restricts the entry of passengers into the rest of the boarding / alighting passage A2.

As shown in FIGS. 4 and 5, the plurality of first-stage bar members 31 are connected to each other by a connecting member 310 provided at the rear end portion in the direction protruding from the door pocket 11. The connecting member 310 is fixed to the first-stage bar member 31 so as to move with the movement of the first-stage bar member 31 in the door pocket 11. The connecting member 310 extends in the vertical direction and is attached to the platform P side surface of the first stage bar member 31 in the thickness direction of the door pocket 11.

As shown in FIGS. 4 and 5, the plurality of second-stage bar members 32 are connected to each other by a connecting member 320 provided at the front end portion in the direction protruding from the first-stage bar member 31. The connecting member 320 is fixed to the second-stage bar member 32 on the boarding / alighting passage A2 so as to move with the movement of the second-stage bar member 32.

Like the connecting member 220, the connecting member 320 extends in the vertical direction, and its lower end 320a is from the second step bar member 32 provided at the lowermost position in the vertical direction among the plurality of second step bar members 32.

You may be doing it. FIG. 12 shows an example in which the connecting member 220 has a convex portion 220c and the connecting member 330 has a concave portion 320c. Note that FIG. 12 is a top view of the vicinity of the front end portion of the bar member as viewed from above in the vertical direction. By having the convex portion 220a and the concave portion 320c in this way, the connecting member 220 and the connecting member 230 can be accurately abutted against each other. In particular, this configuration is effective when the lengths of the bar members 20 and 30 are increased. Further, as shown in FIG. 12, the convex portion 220c has a shape inclined in the thickness direction (X1 and X2 directions shown in FIG. 12) so as to taper toward the front, and the concave portion 220c has a shape corresponding to the concave portion 320c. It is good to say. By adopting such a configuration, even if the bar member 20 and the bar member 30 are displaced in the thickness direction during movement, the concave portion 320c guides the movement of the convex portion 220c. Become. Therefore, the connecting member 220 and the connecting member 230 can be matched with each other with higher accuracy. The convex portion 220c and the concave portion 320c may be formed on the entire connecting members 220 and 230 in the vertical direction, or may be formed on a part thereof.

Further, the drive mechanism in the gate device 1 will be described with reference to FIGS. 6 to 8. FIG. 6 is a perspective view showing a drive mechanism of the gate device according to the present embodiment and a structure around the drive mechanism. In FIG. 6, the door pocket 11 is shown by a broken line to show the internal structure of the door pocket 11, but the internal structure of the door pocket 11 is not actually visible from the outside. 7A to 7C are schematic views illustrating the operation of the drive mechanism of the gate device according to the present embodiment. FIG. 8 is a perspective view illustrating a drive mechanism for driving the second stage bar member. Note that FIG. 8 is a view of the gate device 1 as viewed from the platform P side. Further, in FIG. 8, in order to show the internal configurations of the first-stage bar member 21 and the second-stage bar member 22, a part of the configuration on the platform P side is omitted.

The bar member 20 and the bar member 30 have opposite projecting directions in the width direction of the door pocket 11, but the internal structure and drive system are the same. In the following description, the bar member 20 will be described as an example, and the details of the bar member 30 will be omitted.

First, the drive mechanism 50 for moving the first stage bar member 21 will be described. The drive mechanism 50 includes a motor 51, a pulley 52, guide rollers 53a and 53b, and a drive belt 54. The drive belt 54 is hung on the pulley 52, the guide rollers 53a, and 53b, one end 54a is fixed to the front end portion of the first stage bar member 21 in the protruding direction, and the other end 54b is the first stage bar member. It is fixed to the rear end of the projecting direction of 21. The pulley 52, the guide rollers 53a, and 53b are rotatably provided about a shaft extending in the vertical direction, and the drive belt 54 is fixed to the side surface of the first stage bar member 21 on the line side. There is.

The motor 51 rotationally drives the pulley 52. The drive belt 54 moves as the pulley 52 rotates. For example, it is preferable that a gear is formed on the inner surface of the drive belt 54, and a gear that meshes with the gear of the drive belt 54 is formed on the peripheral surface of the pulley 52 on which the drive belt 54 is hung.

From the state shown in FIG. 7A, the drive belt 54 moves from the left side to the right side in the drawing by rotating the pulley 52 counterclockwise in the drawing (in the direction of the arrow in FIG. 7B). As a result, the first stage bar member 21 is accommodated inside the door pocket 11 from the state of protruding from the door pocket 11 (see FIG. 7C). That is, the first stage bar member 21 moves from the regulated position to the allowable position.

On the other hand, when the pulley 52 rotates clockwise in the drawing (opposite direction of the arrow in FIG. 7B), the drive belt 54 moves from the right side to the left side in the drawing. As a result, the first-stage bar member 21 is in a state of protruding from the door pocket 11 from the state of being housed inside the door pocket 11 (see FIG. 7A). That is, the first stage bar member 21 moves from the allowable position to the regulated position.

The door pocket 11 has an insertion hole 11a through which the first stage bar member 21 is inserted on a side surface (a surface facing the boarding / alighting passage A1). A plurality of insertion holes 11a are provided corresponding to the plurality of first bar members 21. Of the plurality of first-stage bar members 21, the insertion hole 11a corresponding to the first-stage bar member 21 provided with the drive mechanism 50 may be larger than the other insertion holes 11a. As described above, the drive mechanism 50 has a drive belt 54 fixed to the front end portion and the rear end portion of the first stage bar member 21. Since the drive belt 54 is fixed to the front end and the rear end of the first stage bar member 21, the drive belt 54 also passes through the insertion hole 11a as the first stage bar member 21 moves. Moving. It is necessary to increase the insertion hole 11a by the amount that the drive belt 54 passes through. In the present embodiment, since the drive mechanism 50 is provided in the first stage bar member 21 provided at the lowermost position in the vertical direction, the size of the insertion hole 11a provided at the lowermost position in the vertical direction is set to be different from that of the other insertion holes 11a. It was made larger in comparison (see FIG. 6).

Next, the drive mechanism 60 for moving the second stage bar member 22 will be described. The drive mechanism 60 includes a motor 61, a drive shaft 62, a shaft support portion 63, and a motor control belt 64.

The motor 61 is fixed to the rear end of the first stage bar member 21 in the protruding direction. The drive shaft 62 is housed inside the first stage bar member 21, and is rotated by a drive force from the motor 61. A spiral groove is formed on the peripheral surface of the drive shaft 62. The drive shaft 62 is also called a ball screw.

The shaft support portion 63 has an insertion hole through which the drive shaft 62 is inserted, and the inner surface of the insertion hole has a spiral groove that meshes with a spiral groove formed on the peripheral surface of the drive shaft 62. It is formed. With such a configuration, as the drive shaft 62 rotates, the shaft support portion 63 moves in the direction in which the drive shaft 62 extends relative to the drive shaft 62.

Further, the shaft support portion 63 is fixed to the second stage bar member 22. Therefore, as the drive shaft 62 rotates, the shaft support portion 63 moves in the direction in which the drive shaft 62 extends relative to the drive shaft 62, so that the second stage bar member 22 moves with respect to the drive shaft 62. Therefore, the drive shaft 62 relatively moves in the extending direction. Therefore, as the drive shaft 62 rotates, the second-stage bar member 22 moves in the direction in which the drive shaft 62 extends relative to the first-stage bar member 21.

In FIGS. 7A to 7C, the drive shaft 62 rotates in one direction so that the second-stage bar member 22 is housed inside the first-stage bar member 21 from a state of protruding from the first-stage bar member 21. It shows that it will be in a state of being. That is, it indicates that the second stage bar member 22 moves from the regulated position to the allowable position.

The motor control belt 64 supplies electric power to the motor 61 and controls the drive of the motor 61. One end of the motor control belt 64 is connected to a power source, a control device, or the like arranged inside the door pocket 11, and the other end is connected to the motor 61.

As described above, the motor 61 is fixed to the first stage bar member 21 and moves as the first stage bar member 21 moves. The shape of the motor control belt 64 can be deformed as the first-stage bar member 21 moves, and even when the first-stage bar member 21 is moving, electric power or the like can be stably applied to the motor 61. Can be supplied. Instead of the motor control belt 64, wiring or the like whose shape is deformed with the movement of the first stage bar member 21 may be used.

As shown in FIG. 6 and the like, the door pocket 11 may have accommodation areas 111 and 112 for accommodating the drive mechanism 50. In the door pocket 11, the thickness of the portion where the accommodating areas 111 and 112 are provided is thicker than that of the other areas. By making only a part of the door pocket thick in this way, it is possible to secure an area for accommodating the drive mechanism 50 and prevent the entire door pocket 11 from becoming large. Further, in the present embodiment, the accommodating areas 111 and 112 are formed on the track side of the door pocket 11. Therefore, the accommodation areas 111 and 112 do not interfere with the passengers moving on the platform P.

Further, in the present embodiment, a drive mechanism 50 for driving the first stage bar member 21 provided at the lowermost position in the vertical direction among the plurality of first stage bar members 21 is provided. The first-stage bar member 21 other than the first-stage bar member 21 is linked to the first-stage bar member 21 driven by the drive mechanism 50 by the connecting member 210 so as to be interlocked with each other. With such a configuration, a plurality of first stage bar members 21 can be moved without providing a plurality of drive mechanisms 50. That is, a plurality of first stage bar members 21 can be moved with a simple configuration.

Similarly, in the present embodiment, a drive mechanism 60 for driving the second-stage bar member 22 provided at the lowermost position in the vertical direction among the plurality of second-stage bar members 22 is provided. The second-stage bar member 22 other than the second-stage bar member 22 is linked to the second-stage bar member 22 driven by the drive mechanism 60 by the connecting member 220 so as to be interlocked with each other. With such a configuration, a plurality of second-stage bar members 22 can be moved without providing a plurality of drive mechanisms 60. That is, a plurality of second-stage bar members 22 can be moved with a simple configuration.

Further, in the present embodiment, a configuration is adopted in which the drive mechanism 50 and the drive mechanism 60 drive the first-stage bar member 21 and the second-stage bar member 22 provided at the lowermost position in the vertical direction. As a result, the drive mechanism 50 and the drive mechanism 60 can be arranged downward in the vertical direction, and the center of gravity of the gate device 1 can be lowered. As a result, the fixation of the gate device 1 to the platform P can be stabilized.

7A to 7C show an example in which the movement of the first stage bar member 21 by the drive mechanism 50 and the movement of the second stage bar member 22 by the drive mechanism 60 are performed at overlapping timings. With such a configuration, it is possible to move between the state in which boarding / alighting in the boarding / alighting passage A is restricted by the gate device 1 and the state in which boarding / alighting is permitted in a shorter time. As a result, the time that the gate device 1 is in the open state can be shortened, and the safety is improved. However, the movement of the first stage bar member 21 by the drive mechanism 50 and the movement of the second stage bar member 22 by the drive mechanism 60 may be performed at a timing that does not overlap. That is, for example, the first-stage bar member 21 may be projected from the door pocket 11 first, and then the second-stage bar member 22 may be projected from the first-stage bar member 21. Similarly, for example, the second-stage bar member 22 may be housed in the first-stage bar member first, and then the first-stage bar member 21 may be housed in the door pocket 11.

The drive mechanism 50 and the drive mechanism 60 shown in the present embodiment are examples, and are not limited thereto. For example, as a drive mechanism for driving the first stage bar member 21, a drive mechanism including a motor, a pinion gear rotationally driven by the motor, and a first stage bar member 21 having a rack gear meshing with the pinion gear formed on the surface thereof. May be adopted.

Next, the slide structure of the second stage bar member 22 with respect to the first stage bar member 21 will be described with reference to FIGS. 9 and 10. FIG. 9 is a perspective view showing the internal structures of the first-stage bar member and the second-stage bar member. FIG. 10 is a cross-sectional view showing a cross section of the first-stage bar member and the second-stage bar member cut out on a plane perpendicular to the extending direction. FIG. 11 is a cross-sectional view showing a cross section of the first-stage bar member and the second-stage bar member cut out on a plane perpendicular to the extending direction. 9 and 10 show the bar member 20 provided at the uppermost position in the vertical direction, and FIG. 11 shows the bar member 20 provided at the lowermost position in the vertical direction.

As described above, the second stage bar member 22 is housed inside the first stage bar member 21. Further, the first-stage bar member 21 and the second-stage bar member 22 have a rectangular cross section cut out on a plane perpendicular to the direction in which they extend, and the inside is hollow.

A rail member 215 is provided on the inner surface of the first stage bar member 21. The rail member 225 is provided on the outer surface of the second-stage bar member 22.

Further, the rail member 215 is provided with a support member 235 that supports the rotating body 80. The support member 235 is a member that extends in the direction in which the rail member 215 extends. Further, as shown in FIG. 9, a plurality of rotating bodies 80 are provided side by side in the direction in which the support member 235 extends. The rotating body 80 may be, for example, a sphere or a wheel. In FIG. 9, the rail member 215 is not shown in order to show the rotating body 80.

The rotating body 80 is arranged in contact with the guide portion 215a of the rail member 215 and the guide portion 225a of the rail member 225, so that the second stage bar member 22 moves between the regulated position and the allowable position. As a result, it receives frictional force and rotates between the rail member 215 and the rail member 225. It is preferable that each of the plurality of rotating bodies 80 is fitted in a hole formed in the support member 235, and is rotatably supported around a shaft 235a formed so as to cross the hole.

In this way, by adopting the configuration using the rotating body 80, the frictional resistance can be reduced, and the second stage bar member 22 can be smoothly moved with respect to the first stage bar member 21. .. Further, since the load is distributed to the plurality of rotating bodies 80, the load acting on the bar member 20 can be dispersed in the stretching direction. Therefore, it is possible to suppress the local load from being generated in the bar member 20. However, the present invention is not limited to this, and the rail member 215 and the rail member 225 are in direct contact with each other without using the rotating body 80, and the rail member 215 and the rail member 215 move as the second-stage bar member 22 moves. The configuration may be such that the 225 slides.

Further, in the present embodiment, the rotating body 80 and the support member 235 for supporting the rotating body 80 are provided on the first stage bar member 21. If the weight of the front end side of the bar member 20 becomes heavy, the bar member 20 tends to bend. By providing the rotating body 80 and the support member 235 on the first stage bar member 21 on the rear end side of the bar member 20, the bar member 20 is bent as compared with the case where they are provided on the second stage bar member 22. Can be suppressed.

Further, the second-stage bar member 22 is cantilevered with respect to the first-stage bar member 21, and the inner surface of the first-stage bar member 21 and the outer surface of the second-stage bar member 22 are not in contact with each other. It is good. That is, as shown in FIG. 10, the second-stage bar member 22 may be accommodated with a gap G inside the first-stage bar member 21. As a result, no frictional force is generated between the inner surface of the first stage bar member 21 and the outer surface of the second stage bar member 22, so that the second stage bar member 22 can be moved more smoothly. Note that FIG. 10 shows an example in which the first-stage bar member 21 and the second-stage bar member 22 are not in contact with each other over the entire circumference, but the present invention is not limited to this, and the gap G is at least partially formed. It suffices to have. Further, by adopting a configuration in which the second-stage bar member 22 is cantilevered and supported, one rail member 215 and 225 are required for one bar member, and the configuration is simplified.

In the present embodiment, since the cross-sectional shape of the first-stage bar member 21 is rectangular and the inner surface thereof is flat, the posture on the inner surface of the first-stage bar member 21 is higher than that in the case where the cross-sectional shape is circular or the like. The rail member 215 can be easily attached by stabilizing. Similarly, in the present embodiment, since the cross-sectional shape of the second-stage bar member 22 is rectangular and the outer surface thereof is flat, the outer surface of the second-stage bar member 22 is different from the case where the cross-sectional shape is circular or the like. The rail member 225 can be easily attached by stabilizing the posture.

The rail member 225 may be provided on the outer surface of the wall portion 228 on the track side of the wall portions constituting the second stage bar member 22. As a result, the rail member 225 cannot be seen by the passengers on the platform P, so that the appearance of the gate device 1 is improved.

In the present embodiment, among the plurality of bar members 20, the structures shown in FIGS. 9 and 10 are adopted for the uppermost bar member 20 and the lowermost bar member 20 in the vertical direction. As described above, the lowermost bar member 20 is provided with a drive shaft 62 or the like for driving the second stage bar member 22. As shown in FIG. 11, the drive shaft 62 may be arranged inside the hollow second-stage bar member 22, and the rail member 225 may be arranged outside.

Although FIG. 4 and the like show an example in which a plurality of first-stage bar members 21 are provided at the rear ends and have connecting members 210 for connecting them to each other, the plurality of first-stage bar members 21 are provided. It is not necessary that there is only one connecting member to be connected. For example, as shown in FIG. 13, a connecting member 230 that is provided at the front end of a plurality of first-stage bar members 21 and connects them to each other may be further provided. The connecting member 230 may be arranged adjacent to the door pocket 11 on the outside of the door pocket 11 in a state where the first stage bar member 21 is in an allowable position. In this way, the strength of the bar member 20 can be improved by connecting the plurality of first stage bar members 21 to each other at a plurality of locations. Similarly, as shown in FIG. 13, a connecting member 330 which is provided at the front end portion of the plurality of first stage bar members 31 and connects them to each other may be further provided.

As described above, in the present embodiment, since the bar member 20 is a two-stage type, that is, the first-stage bar member 21 and the second-stage bar member 22 protruding from the first-stage bar member 21 are provided. Since the bar member 20 including the bar member 20 is used, the width of the boarding / alighting passage A can be made wider. As a result, it becomes possible to handle various railroad vehicles with different numbers of doors and their intervals. Further, since the bar member 20 is a two-stage type, the width of the door pocket 11 can be made narrower than the length of the bar member 20. As a result, the size of the gate device 100 can be reduced, and the time and cost required for the installation work can be reduced.

Further, since the second stage bar member 22 can be moved while the first stage bar member 21 is moving, the regulated position and the allowable position are compared with the configuration using one bar member which is not a two-stage type. The travel time between and can be shortened. Therefore, the time that the gate device 1 is in the open state can be shortened, and the safety is improved.
