The gate device 100 is a gate provided to ensure the safety of passengers such as prevention of falling from the platform 1 to the track, and a plurality of gate devices 100 are provided along the edge of the track 1 in the platform 1. In addition, the platform 1 is a boarding place provided for passengers to get on and off the railway vehicle at a station where a railway vehicle (not shown) such as a train or a bullet train traveling on the railway line stops.

Each of the plurality of gate devices 100 includes a first gate 10, a second gate 20, an installation member 30, and a support installation member 50.

The installation member 30 is fixedly installed on the platform 1 so as to be adjacent to the boarding passage. Here, the boarding / exiting passage means that when the railway vehicle stops at the station, the passenger inside the gate device 100 on the platform 1 moves so as to get into the railway vehicle, or the platform 1 from within the railway vehicle. It is defined as a passage that passes when moving to the inside of the upper gate device 100. In the present embodiment, the getting-on / off passage is an area between the installation member 30 and the support installation member 50.

In FIG. 1, FIG. 2, etc., the installation member installed adjacent to the entrance / exit passage A is indicated by the installation member 30a, and the installation member installed adjacent to the entrance / exit passage B is indicated by the installation member 30b. However, in the following description, when there is no need to distinguish between them, it will be simply expressed as the installation member 30. The same applies to the first gate 10, the second gate 20, and the components included therein.

The first gate 10 includes a lower bar 11 and an upper bar 12 that are rotatably attached to the installation member 30.

The lower bar 11 restricts the entry of the entry / exit passage into the part of the installation member 30 and allows the entry of the entry / exit passage to the part of the installation member 30 by standing above the installation member 30. It attaches to the installation member 30 so that rotation between the permissible positions is possible. The upper bar 12 rises above the installation member 30 and restricts entry into a part of the getting-on / off passage on the installation member 30 side and allows entry into a part of the installation member 30 on the installation member 30 side. It is attached to the installation member 30 so as to be rotatable between the allowable positions.

Further, the rotation axis of the upper bar 12 is provided above the rotation axis of the lower bar 11 and is provided on the installation member 30 on the side away from the boarding passage. As will be described later, in the present embodiment, the lower bar 11 and the upper bar 12 rotate so as to maintain a parallel state. That is, when the lower bar 11 is in the restricted position, the upper bar 12 is also in the restricted position, and when the lower bar 11 is in the allowed position, the upper bar 12 is also in the allowed position.

In the present embodiment, one driving source is provided inside the installation member 30, and the lower bar 11 and the upper bar 12 are configured to be interlocked by the driving force from the driving source. Yes. Specifically, as shown in FIGS. 3 and 4, a motor (not shown), a pulley 33 that rotates as the motor rotates, and a lower bar 11 rotate inside the installation member 30. A pulley 110 that rotates integrally with the shaft, a pulley 210 that rotates integrally with the rotation shaft of the upper bar 12, a pulley 80 that receives a biasing force from a counter spring 90 described later, and a belt 60 are provided. A gear is formed on the peripheral surface of each pulley around which the belt 60 is stretched, and irregularities are formed on the inner surface of the belt 60 so as to mesh with the gear of each pulley. One end of the belt 60 is fixed to the pulley 33, and the other end is fixed to the pulley 80.

Hereinafter, with reference to FIG. 3 and FIG. 4, an operation when the lower bar 11 and the upper bar 12 are rotated from the restriction position to the allowable position will be described. First, when the motor rotates, the pulley 33 rotates in the direction R3 in FIG. 3, and the belt 60 is conveyed in the direction R4 in FIG. As the belt 60 is conveyed in the R4 direction in FIG. 3, the rotation shafts of the pulley 110 and the lower bar 11 rotate in the R1 direction in FIG. As a result, the lower bar 11 rotates from the restriction position shown in FIG. 3 to the allowable position shown in FIG.

Further, as the belt 60 is conveyed in the R4 direction in FIG. 3, the rotation axes of the pulley 210 and the upper bar 12 rotate in the R2 direction in FIG. As a result, the upper bar 12 rotates from the restriction position shown in FIG. 3 to the allowable position shown in FIG.

In addition, when rotating the lower bar 11 and the upper bar 12 from the allowable position to the restricting position, the motor may be driven so that the pulley 33 rotates in the direction opposite to the R3 direction in FIG.

Furthermore, a counter spring 90 as an urging means is provided inside the installation member 30. The pulley 80 is integrally provided with a support portion 81 that protrudes in the circumferential direction. Further, the support portion 81 is provided with a mounting portion 82 to which one end side of the counter spring 90 is attached so as to be rotatable. And the other end side of the counter spring 90 is attached to the base 31 fixed to the inner wall of the installation member 30. As shown in FIG. 3, when the upper bar 12 is in the restricting position, the counter spring 90 is stretched by being pulled in the vertical direction, and exerts an urging force acting on the pulley 80 in the R5 direction. It is generated. On the other hand, as shown in FIG. 4, when the upper bar 12 is in the allowable position, the counter spring 90 is in a contracted state and does not generate an urging force against the pulley 80, or the state shown in FIG. This produces a smaller biasing force. As described above, since the counter spring 90 generates an urging force, the upper bar 12 in the allowable position does not drop suddenly due to gravity even when a failure or the like occurs in the drive source, and the vicinity of the gate device 100. It is possible to prevent a passenger from being in danger. Further, since the counter spring 90 generates an urging force acting in the R5 direction with respect to the pulley 80, it is possible to reduce the driving force required when the upper bar 11 is rotated from the restricted position to the allowable position. It becomes.

The internal structure of the installation member 30 is not limited to that shown in FIGS. 3 and 4, and may have other configurations as long as the lower bar 11 and the upper bar 12 can be rotated. . For example, a drive source for rotating the lower bar 11 and a drive source for rotating the upper bar 12 may be provided. Further, in preparation for an emergency or the like, the lower bar 11 and the upper bar 12 may be configured to be manually rotatable.

The lower bar 11 and the upper bar 12 are preferably made of a relatively light metal such as aluminum, a resin, or the like from the viewpoint of weight reduction. In the present embodiment, the lower bar 11 and the upper bar are rectangular bars, but the present invention is not limited to this, and round bars may be used. In addition, when using a square bar-like bar, it is preferable to use a bar with rounded corners in consideration of safety.

Further, the gate device 100 may have at least one erection bar 15 for preventing passengers from going through the area between the lower bar 11 and the upper bar 12. The erection bar 15 is rotatably provided on the lower bar 11 and the upper bar 12, and is spanned between the lower bar 11 and the upper bar 12. Although detailed illustration is omitted, both end portions of the erection bar 15 may have a link structure that can freely rotate with respect to the lower bar 11 and the upper bar 12. The erection bar 15 may be made of the same material as the lower bar 11 and the upper bar 12. Or the construction bar 15 may be comprised with a rope etc. from a viewpoint of weight reduction. In that case, it is not necessary to employ a link structure, and the mounting structure of the erection bar 15 is simplified.

The second gate 20 is a frame for restricting entry into the remaining part of the getting-on / off passage. Here, the remaining part of the getting-on / off passage is defined as an area farther from the installation member 30 than the first gate 10 at the restriction position in the getting-on / off passage. That is, the second gate 20 is a frame body that restricts entry into the boarding / alighting passage in a region farther from the installation member 30 than the first gate 10.

The second gate 20 includes a rotation frame portion 21 that is rotatably provided at the distal end portion of the lower bar 11 and the distal end portion of the upper bar 12. Further, the second gate 20 includes a lower frame 22 fixed to the rotating frame portion 21, an upper frame portion 23 fixed to the rotating frame body 21, a lower frame portion 22, and an upper frame portion. 23 and a counter frame portion 24 provided at a position that is fixed with respect to the rotary frame portion 21 and is opposed to the rotating frame portion 21. That is, the second gate 20 is a frame that is integrally formed of the rotating frame portion 21, the lower frame portion 22, the upper frame portion 23, and the opposing frame portion 24.

The second gate 20 has a line segment connecting the rotation axis of the lower bar 11 and the rotation axis of the upper bar 12 and the rotation of the second gate 20 with respect to the lower bar 11 when viewed from the getting-on / off direction. The line segment connecting the axis and the rotation axis of the second gate 20 with respect to the upper bar 12 may be provided so as to be parallel to each other and have the same length. With this configuration, the second gate 20 moves in the vertical direction and the horizontal direction as the lower bar 11 and the upper bar 12 rotate, and the posture thereof is constant with respect to the horizontal direction. It becomes.

Also, the gate device 100 may have at least one erection bar 25 for preventing passengers from going through the area between the lower frame portion 22 and the upper frame portion 23. The erection bar 25 is stretched between the lower frame portion 22 and the upper frame portion 23 or between the upper frame portion 23 and the opposing frame portion 24. Both end portions of the erection bar 25 are preferably provided integrally with each of the lower frame portion 22, the upper frame portion 23, and the opposing frame portion 24. The erection bar 25 may be made of the same material as that of the second gate 20. Alternatively, the erection bar 25 may be configured with a rope or the like from the viewpoint of weight reduction.

In the present embodiment, by adopting a configuration in which a plurality of erection bars 25 are spanned, it is possible for the passenger to visually recognize the track side as viewed from the platform 1 side. Therefore, the feeling of blockage due to the plurality of gate devices 10 being installed side by side on the platform 1 is reduced. Similarly, since the platform 1 side is visible when viewed from the track side, it is easy to check the state of passengers and the like on the platform 1 from the driver driving the railway vehicle, and improvement in safety can be expected.

In addition, since the second gate 20 is composed of a frame body having a gap between the frames, the influence of wind pressure due to the passage of the railway vehicle is reduced, and the second gate 20 swings in the getting-on / off direction. Instability can be suppressed.

In addition, instead of the second gate 20, a plate-like member may be provided on the lower bar 11 and the upper bar 12 so as to be rotatable. In this case, in order to improve the visibility when the platform 1 is viewed from the railway vehicle and the visibility when the track side is viewed from the platform 1, the plate-like member is preferably transparent.

Further, as shown in FIG. 5 and the like, the second gate 20 may have a support portion 26 that protrudes toward the platform 1 in a state where the lower bar 11 and the upper bar 12 are in the restriction positions. The support portion 26 abuts on the platform 1 and supports the second gate 20 in a state where the lower bar 11 and the upper bar 12 are in the restriction positions. Thereby, in the state where the lower bar 11 and the upper bar 12 are in the restriction position, the postures of the first gate 10 and the second gate 20 are stabilized, and the horizontal state is maintained.

In the present embodiment, the example in which the support portion 26 is provided in the second gate 20 has been described. However, the present invention is not limited to this, and in a state where the lower bar 11 and the upper bar 12 are in the restriction position, Any material that contacts the platform 1 and supports at least one of the first gate 10 and the second gate 20 may be used. That is, the support portion 26 may be provided on the lower bar 11. Further, the number of support portions 26 is not limited to one, and a plurality of support portions 26 may be provided.

This is because the support portion 26 is preferably made of a soft material in order to ensure the safety of passengers near the gate device 100. In particular, the tip portion of the support portion 26 that contacts the platform 1 may be made of an elastic member such as rubber. Further, a groove or the like for positioning the support portion 26 may be formed on the platform 1.

Further, as shown in FIG. 6, the support portion 26 has a lower portion so as to restrict the rotation of the second gate 20 relative to the lower bar 11 in a state where the lower bar 11 and the upper bar 12 are in the allowable positions. It is good to contact the side bar 11. And the surface which contact | abuts the lower bar 11 among the support parts 26 is good in it being a surface extended in a perpendicular direction. With such a configuration, the posture of the second gate 20 is stabilized and the horizontal state is maintained in a state where the lower bar 11 and the upper bar 12 are in the allowable positions.

In addition, the support part 26 should just restrict | limit rotation of the 2nd gate 20 with respect to the lower bar 11 in the state in which the lower bar 11 exists in a permissible position. It may be provided on the side bar 11. In this case, the support portion 26 provided on the lower bar 11 comes into contact with the lower frame portion 22 of the second gate 20, so that the posture of the second gate 20 is stabilized.

Further, as shown in FIG. 5 and the like, the second gate 20 is a restriction that restricts the movement of the first gate 10 in the getting-on / off direction with respect to the second gate 20 in a state where the first gate 10 is in the restriction position.

Parts

27 and 28. The restricting portion 27 is provided in the lower frame portion 22 so as to sandwich the lower bar 11. The restricting portion 28 is provided in the upper frame portion 23 so as to sandwich the upper bar 12. Thereby, in the state in which the 1st gate 10 exists in a control position, connection with the 1st gate 10 and the 2nd gate 20 will be made strong. Therefore, the strength of the first gate 10 and the second gate 20 with respect to the direction pushed from the getting-on / off direction is improved. The longer the bar length, the weaker the strength in the getting-on / off direction tends to be. However, by using the restricting

portions

27 and 28, the length of the bar can be increased and the strength in the getting-on / off direction can be improved. Become. The restricting portion may be provided in the first gate 10 so as to sandwich the lower frame portion 22 and the upper frame portion 23 of the second gate 20.

The support installation member 50 is fixedly installed on the platform 1 so as to be adjacent to the installation member 30 on the opposite side of the entrance / exit passage, and the lower bar 11 and the upper bar 12 are in a restricted position. The tip of the second gate 20 is supported. Moreover, as shown in FIG. 1 etc., the support installation member 50a is good to arrange | position so that the installation member 30b of the gate apparatus 100 provided in order to control the approach to the boarding / alighting passage B may be adjoined. The support installation member 50a may be configured integrally with the installation member 30b. Alternatively, a bar or a plate-like member may be provided between the support installation member 50a and the installation member 30b for restricting passenger entry.

Further, as shown in FIG. 7, the support installation member 50 is formed with a support groove 510a so as to form a support bottom surface 511a and a support side surface 512a as a position shift restricting portion. Similarly, a support groove 520a is formed in the support installation member 50 so as to form a support side surface 522a as a support bottom surface 521a and a position deviation restricting portion. And the front-end | tip part 222a of the lower frame part 22a of the 2nd gate 20a is supported by the support bottom face 511a in the state in which the 1st gate 10a exists in a control position. Similarly, the front end portion 232a of the upper frame portion 23a of the second gate 20a is supported by the support bottom surface 521a in a state where the first gate 10 is in the restriction position.

In addition, the front end portion 222a of the lower frame portion 22a of the second gate 20a is moved by the support side surface 512a formed so as to sandwich the front end portion 222a in the getting-on / off direction when the first gate 10a is in the restricting position. The positional deviation in the direction is regulated. Similarly, the front end portion 232a of the upper frame portion 23a of the second gate 20a is supported by the support side surface 522a formed so as to sandwich the front end portion 232a in the getting-on / off direction in a state where the first gate 10a is in the restriction position. The positional deviation in the boarding / alighting direction is restricted.

Note that the support groove 510 may be formed so as to increase in width from the lower side in the vertical direction toward the upper side. That is, the support groove 510 is preferably formed so that the interval between the support side surfaces 512 becomes wider from the lower side to the upper side in the vertical direction. It is preferable that the distance between the support side surfaces 512 is wider than the diameter of the front end portion 222 of the lower frame portion 22 of the second gate 20 at least above in the vertical direction. There is a possibility that the posture of the second gate 20 in the boarding / alighting direction becomes unstable due to the influence of the deflection of the bar or the wind pressure. By increasing the groove width of the support groove 510 above the vertical direction, the second gate 20 can be accurately obtained. The front end 222 can be fitted into the support groove 510. Further, by narrowing the width in the lower portion of the vertical direction, specifically, by making the groove width of the support groove 510 equal to the diameter of the tip portion 222 of the lower frame portion 22 of the second gate 20, It is possible to suppress displacement of the front end portion 222 in the boarding / alighting direction. The support groove 520 may have the same configuration.

As described above, in the gate device 100 according to the present embodiment, the installation member 30 does not need to accommodate a gate that restricts entry into the getting-on / off passage, and thus the installation member 30 can be downsized. . As a result, the weight of the gate device 100 can be reduced. In addition, since it is not necessary to accommodate the gate in the installation member 30, the lengths of the first gate 10 and the second gate 20 can be increased regardless of the size of the installation member 30. Therefore, it is possible to increase the width of the getting-on / off passage, and it is possible to provide the gate device 100 corresponding to the doors of the railway vehicle at various intervals. In addition, when the gate device 100 has a ceiling, a roof, or the like, the length of the lower bar 11 and the upper bar 12 is limited. In this embodiment, the length of the second gate 20 is increased. Accordingly, the width of the getting-on / off passage can be increased without increasing the lengths of the lower bar 11 and the upper bar 12.

Further, in the configuration in which the gate including the bar is accommodated in the installation member 30, there is a possibility that a housing failure may occur due to bending of the bar or the like. However, such a problem does not occur in the configuration of the present embodiment.
