For example, between the first door 1A and the second door 2A, between the second door 2A and the third door 3A, between the fourth door 4A and the sixth door 6B, the fifth. Each door may be movable so that an opening is formed between the door 5A and the sixth door 6A. With such a configuration, the degree of freedom of the opening position can be further improved.

Further, each door may be movable without limitation as long as it is on the door passage and within a range until it comes into contact with adjacent doors. For example, the third door 3A shown in FIG. 7 may be movable to a position on the third door passage 13 that comes into contact with the fifth door 5B. Similarly, for example, the sixth door 6D shown in FIG. 7 may be movable to a position on the second door passage 12 that comes into contact with the second door 2C. With such a configuration, a railroad vehicle T having a vehicle door wider than the vehicle doors D shown in the first to sixth examples, and a plurality of vehicle doors D are arranged in close proximity to each other. Even when the railcar T is stopped beside the platform P, an opening having an appropriate width can be formed according to the width of the vehicle door and the interval thereof.

[Drive system for each door]
The door drive system of the gate device 100 will be specifically described with reference to FIGS. 18 to 21. Here, the first door 1 will be described as an example, but the same drive system may be applied to the second door 2 to the sixth door 6.

FIG. 18 is a diagram showing the internal structure of the first door and the structure inside the platform. FIG. 19 is a cross-sectional view showing a cut surface cut along the XIX-XIX cutting line shown in FIG. FIG. 20 is a cross-sectional view showing a cut surface cut along the XX-XX cutting line shown in FIG. FIG. 21 is a cross-sectional view showing a cut surface cut along the XXI-XXI cutting line shown in FIG.

In FIG. 18, in order to show the internal structure of the first door 1, the surface of the housing 1h constituting the exterior of the first door 1 on the front side of the paper (inside the platform P) is not shown. .. Further, in FIG. 18, the illustration of the platform P is omitted. Further, in FIG. 18, as in FIG. 4, it is assumed that the left direction in the figure is the front and the right direction is the rear. Further, in FIGS. 19 to 21, hatching is omitted for simplification of the drawings.

The first door 1 has a drive unit 51. The drive unit 51 includes a motor 511 and a train wheel that rotates with the rotation of the motor 511. The motor 511 and a part of the train wheel are housed in the housing 1h that constitutes the exterior of the first door 1.

The train wheel includes a gear 511a that rotates coaxially with the motor 511, a gear 512 that meshes with the gear 511a, a drive pulley 513, and a drive pulley 514. The train wheel also includes a gear 512a that rotates coaxially with the gear 512 together with the gear 512, a drive pulley 513, and a timing belt 515 that is hung on the drive pulley 514. The train wheel also includes a power belt 516 that is hung on a gear 513a that rotates coaxially with the drive pulley 513 and rotates with the drive pulley 513, and a gear 514a that rotates coaxially with the drive pulley 513 and rotates with the drive pulley 513. A gear that meshes with the gear 513a and the gear 514a is formed on the inner peripheral surface of the power belt 516. Further, on the outer peripheral surface of the power belt 516, a gear that meshes with the rack gear 60 described later is formed.

Further, a groove g extending along the edge PE of the platform P is formed in the first door passage 11 provided on the platform P. The groove g includes a deep groove g1 and a shallow groove g2 adjacent to the deep groove g1. As shown in FIG. 19, a rack gear 60 is provided in the shallow groove g2. The rack gear 60 is fixed to the platform P. Further, the rack gear 60 is provided so as to mesh with a gear formed on the outer peripheral surface of the power belt 516. Further, as shown in FIGS. 18 and 20, the above-mentioned drive pulley 513 and drive pulley 514 are arranged in the groove g.

The driving force from the motor 511 is transmitted to the power belt 516 via the train wheel train. As a result, the power belt 516 rotates clockwise or counterclockwise in FIG. 18 in a state where the gear formed on the outer peripheral surface thereof meshes with the rack gear 60 and is hung on the gear 513a and the gear 514a. To do.

When the power belt 516 is rotated clockwise in FIG. 18, the power belt 516 that meshes with the rack gear 60 moves to the left in FIG. 18 relative to the rack gear 60. As a result, the first door 1 moves to the left (forward) on the first door passage 11 of the platform P.

On the other hand, when the power belt 516 is rotated counterclockwise in FIG. 18, the power belt 516 that meshes with the rack gear 60 moves to the right in FIG. 18 relative to the rack gear 60. As a result, the first door 1 moves to the right (rearward) on the first door passage 11 of the platform P.

Further, it is preferable that the first door 1 is fixed to the housing 1h and has a support plate 70 projecting downward. Although FIG. 18 shows an example in which two support plates 70 are provided, the number of support plates 70 may be one or three or more. As shown in FIG. 19, the support plate 70 may be inserted into the deep groove g1 formed in the platform P.

By providing the support plate 70 in this way, the first door 1 can be supported by the platform P and can maintain an independent state on the platform P. Further, even if it is pushed by a passenger or affected by the wind pressure generated when the railway vehicle T passes through, it maintains an independent state and does not fall down.

In the configuration in which the device becomes large as a whole as in Patent Document 1, it is necessary to increase the thickness of the lower portion in order to make the door pocket and the door independent. However, in the gate device 100 according to the present embodiment, the thickness of the lower portion needs to be increased. Even when the thickness of the upper part and the lower part are substantially the same, the door can stand on its own. As described above, in the gate device 100 according to the present embodiment, the support structure can be simplified and miniaturized.

Further, the first door 1 may have wheels 81 and 82 under the first door 1. The wheels 81 and 82 rotate on the first door passage 11 of the platform P as the first door 1 moves. As described above, since the first door 1 has the wheels 81 and 82, it can smoothly move on the first door passage 11 of the platform P.

Further, as shown in FIGS. 19 to 21, it is preferable that the platform P is formed with a groove g3 into which the groove filling belt 83 described later is fitted. The width of the groove g3 is preferably such that the wheels 81 and 82 fit into the groove g3. The side wall of the groove g3 serves as a guide, and the first door 1 can move straight ahead more smoothly. Further, the wheels 81 and 82 may be wider than the groove g3. In that case, the wheels 81 and 82 will rotate on the platform P above the groove g3. In that case, the wheels 81 and 82 may protrude in the radial direction of the wheels 81 and 82 and have a flange portion having a width enough to fit in the groove g3. As a result, the side wall of the groove g3 serves as a guide for the flange portion, and the first door 1 can smoothly move straight ahead.

Further, as shown in FIG. 18, the first door 1 may have a groove filling belt 83 and a reel 84 capable of winding and unwinding the groove filling belt 83. The groove filling belt 83 has a function of closing the opening of the groove formed in the first door passage 11 of the platform P.

It is preferable that one end of the groove filling belt 83 is wound around the reel 84 and the other end of the groove filling belt 83 is fixed to adjacent doors. In FIG. 18, the other end of the groove filling belt 83 extending from the fourth door 4 adjacent to the first door 1 at the rear is fixed to a stop pin (fixing portion) 85 provided at the lower part of the first door 1. It shows how it is being done. Further, although not shown, the other end of the groove filling belt 83 extending from the first door 1 is similarly provided at the lower part of a fourth door (not shown) adjacent to the first door 1 in front. It should be fixed to the pin.

Further, the wheel 81 may have a function as a guide roller for the groove filling belt 83. FIG. 18 shows how the groove filling belt 83 unwound from the reel 84 is hung on the peripheral surface of the wheel 81.

When the first door 1 moves rearward, the groove filling belt 83 is unwound from the reel 84 housed in the first door 1. As shown in FIG. 21, the unwound groove filling belt 83 is fitted into the groove formed in the first door passage 11.

Of the groove openings formed in the first door passage 11, the region in front of the first door 1 is closed by the groove filling belt 83 extending from the first door 1. Further, among the openings of the grooves formed in the first door passage 11, the region behind the first door 1 is closed by the groove filling belt 83 extending from the fourth door 4. Therefore, the opening of the groove formed in the first door passage 11 is not exposed on the platform P.

By closing the opening of the groove formed in the first door passage 11, it is possible to prevent the danger of the passenger's shoes getting stuck in the groove. In addition, it is possible to prevent rainwater and dust from entering the groove formed in the first door passage 11. As a result, it is possible to prevent a problem or the like from occurring in the driving of the first door 1.

Although detailed description will be omitted, the openings of the grooves formed in the second door passage 12 and the third door passage 13 are similarly the second door 2, the third door 3, and the fifth door. It is preferable that the door 5 and the sixth door 6 are closed by the groove filling belt 83 extending from the door 6.

Further, in the gate device 100 in which the doors move on each of the three door passages, it is preferable to reduce the thickness of each door to suppress the overall thickness. Therefore, as shown in FIG. 18, in the first door 1, the motor 511 is arranged so that the drive shaft O extends in the vertical direction (the direction orthogonal to the thickness direction of the first door 1). As a result, the thickness of the first door 1 is suppressed as compared with the configuration in which the motor 511 is arranged so that the drive shaft O extends in the thickness direction of the door. Since the same configuration is adopted for the second door 2 to the sixth door 6, it is possible to prevent the device as a whole from becoming larger in the thickness direction.

In the present embodiment, one drive unit is arranged on one door. Since the movement of one door is not affected by other doors, the power in the drive unit of one can be minimized. Further, since a plurality of drive units are not accommodated in the housing constituting the exterior of each door, it is possible to prevent the door from becoming large.

As described above, in the gate device 100 according to the present embodiment, it is possible to improve the degree of freedom of the opening position and prevent the device from becoming large.

Further, as shown in FIG. 18, the first door 1 may have a transparent portion 1a that makes the track R side visible when viewed from the platform P side. The transparent portion 1a constitutes a part of the housing 1h, and may be an acrylic plate, a glass plate, or the like. The mechanism or member housed in the housing 1h may be arranged in a region that does not overlap the transparent portion 1a in the vertical direction. That is, for example, the drive unit 51 and the support plate 70 may be arranged below the transparent unit 1a in the vertical direction.

[Modification example of drive system for each door]
A modification of the door drive system of the gate device 100 will be described with reference to FIG. The same components as those shown in FIG. 18 are designated by the same reference numerals, and the description thereof will be omitted.

Includes a gear 513aF that rotates with the 513F. The front wheel train also includes a belt 516F hung on the gear 512aF and the gear 513aF.

Similarly, the rear wheel train is coaxial with the gear 511aR that rotates coaxially with the motor 511R, the gear 512R that meshes with the gear 511aR, the gear 512aR that rotates with the gear 512R coaxially with the gear 512R, the reel 513R, and the reel 513R. Includes a gear 513aR that rotates with the reel 513R above. Further, the rear wheel train includes a belt 516R hung on the gear 512aR and the gear 513aR.

Further, the first door 1 is provided with a connecting belt 88F that is wound and unwound by the reel 513F and a connecting belt 88R that is wound and unwound by the reel 513R.

The driving force from the motor 511F is transmitted to the reel 513F via the front wheel train. As a result, the reel 513F rotates, and the connecting belt 88F is wound and unwound. Similarly, the driving force from the motor 511R is transmitted to the reel 513R via the rear wheel train. As a result, the reel 513R rotates, and the connecting belt 88R is wound and unwound.

Further, as shown in FIG. 22, the fourth door 4 has a drive unit 54. The drive unit 54 has the same configuration as the drive unit 51, and includes a motor 541F, a front wheel train, a motor 541R, and a rear wheel train. The front wheel train includes a gear 541aF, a gear 542F, a gear 542aF, a gear 543aF, a reel 543F, and a belt 546F.

As shown in FIG. 22, one end of the connecting belt 88F is provided so as to be wound up and unwound by the reel 513F of the first door 1, and the other end of the connecting belt 88F is provided so as to be wound up and unwound by the reel 513F of the first door 1. It is provided so as to be wound and unwound by a reel 543R provided in a fourth door 4 adjacent to the front of the door 4.

Further, one end of the connecting belt 88R is provided so as to be wound up and unwound with respect to the reel 513R of the first door 1, and the other end of the connecting belt 88R is behind the first door 1. It is provided so as to be wound up and unwound with respect to the reel 543F provided in the adjacent fourth door 4.

The connecting belt 88F is hung on a guide roller 89F provided at the lower part of the first door 1 and a guide roller 89R provided at the lower part of the fourth door 4 adjacent to each other in front of the first door 1. In a groove (not shown) formed in the first door passage 11, the groove is provided along the groove. Similarly, the connecting belt 88R is hung on a guide roller 89R provided at the lower part of the first door 1 and a guide roller 89F provided at the lower part of the fourth door 4 adjacent to the rear of the first door 1. In the groove (not shown) formed in the first door passage 11, the groove is provided along the groove.

The first door 1 drives the motor 511F so as to wind up the connecting belt 88F by the reel 513F in a state where the rotation of the reel 543R of the fourth door 4 adjacent to the front of the first door 1 is restricted. As a result, it is pulled forward by the connecting belt 88F and moves forward on the first door passage 11.

Further, the first door 1 drives the motor 511R so as to wind up the connecting belt 88R by the reel 513R in a state where the rotation of the reel 543F of the fourth door 4 adjacent to the rear of the first door 1 is restricted. By doing so, it is pulled backward by the connecting belt 88R and moves backward on the first door passage 11.

However, the present invention is not limited to this, and the drive unit 54 of the fourth door 4 may have a function as the first drive unit 51. That is, the first door 1 may move on the first door passage 11 by the driving force of the driving unit 54.

Specifically, the first door 1 is a motor that winds up the connecting belt 88F by the reels 543R of the fourth door 4 adjacent to each other in front of the first door 1 in a state where the rotation of the reel 513F is restricted. By driving the 541R, it may be pulled forward by the connecting belt 88F and moved forward on the first door passage 11.

Similarly, in the state where the rotation of the reel 513R is restricted, the first door 1 winds the connecting belt 88R by the reels 543F of the fourth door 4 adjacent to the rear of the first door 1 so as to wind the motor 541F. By driving, it may be pulled backward by the connecting belt 88R and moved backward on the first passage 11.

As described above, in the modified example, the doors adjacent to each other on the first door passage 11 are connected via the connecting belt, and the doors on the first door passage 11 are connected according to the tension generated by the connecting belt. To move. In the modified example, since the rack gear 60 is not provided in the platform P, the installation work of the gate device 100 can be simplified.

Further, also in the modified example shown in FIG. 22, it is preferable that each door is provided with the groove filling belt 83 shown in FIG. However, the present invention is not limited to this, and the connecting belts 88F and 88R may play the role of the groove filling belt 83. That is, the connecting belt may be configured to close the groove g between the doors connected by the connecting belt. In this case, the groove filling belt 83 and the reel 84 shown in FIG. 22 may be omitted.

The configuration of the drive unit shown with reference to FIGS. 18 and 22 is an example, and the number and arrangement of gears included in the train wheel are not limited to those shown in the drawings. At least, it is preferable that the first door 1 moves on the first door passage 11 by transmitting the driving force of the driving unit 51. The same applies to the second door 2 to the sixth door 6. The electric power supplied to the drive unit may be, for example, transmitted via a cable extending in a groove formed in the platform P or the like.

Further, as shown in FIG. 18 and the like, it is preferable that each door of the gate device 100 has a warning lamp 80. The warning lamp 80 is provided at each end of the housing constituting the exterior of each door in the moving direction of each door. The warning lamp 80 is a lighting device that lights up or blinks when the door makes an emergency stop, for example, when there are passengers on the door passage while the door is moving. By lighting or blinking the warning lamp 80, station staff and the like can visually detect the danger and prevent the occurrence of an accident.

Further, as shown in FIG. 1, it is preferable that each door of the gate device 100 has a display device 90. The display device 90 is provided on the inner surface of the platform P among the housings constituting the exterior of each door, and displays an image showing the moving direction of each door.

In FIG. 1, an arrow indicating the left direction is displayed on the display device 90 of the first door 1A, the fourth door 4A, and the fifth door 5B. Further, an arrow indicating the right direction is displayed on the display device 90 of the third door 3B. Further, the display device 90 of the first door 1B is turned off, and the arrow is not displayed.

This allows passengers to easily recognize in which direction each door is moving. Therefore, the passenger can immediately recognize at which position of the gate device 100 the opening is formed, and can smoothly move from the platform P into the railway vehicle T. Further, by recognizing the moving direction of each door, the passenger can avoid contacting the door moving on the platform P.

Although FIG. 1 shows an example in which the second door 2 and the sixth door 6 do not have the display device 90, these doors may also have the display device 90.

Further, the image displayed on the display device 90 is not limited to the arrow, and may be an image to that effect when the door is moved. For example, the display device 90 may display the characters "this door moves". Alternatively, when the door moves to the right, the display device 90 may display characters such as "move to the right". Further, the display device 90 is not limited to the one that indicates the moving direction, and may be any device that allows the passenger to recognize that the vehicle is moving, for example. For example, the display device 90 may be configured to blink while the door is moving. As a result, the passenger can at least recognize which door moves and which door does not move, and can avoid contact with the moving door.

The display of the image by the display device 90 may be performed before the movement of the door, or may be performed during the movement. Further, the display of the image by the display device 90 may be performed both before and during the movement of the door. By displaying the image before the doors move, the passenger can recognize in advance which doors move and which doors do not move. In addition, by displaying the image while the door is moving, the passenger can avoid contacting the moving door. After the target position of each door is determined by the target position determining unit 30, the display device 90 displays the moving direction by sending a display command together with a drive command sent to the drive unit. Good to do.

The warning lamp 80 described above may have a function as a display device 90. That is, for example, the warning lamp 80 provided on the first door 1 may be turned on when the first door 1 is moved. By turning on the warning lamp 80 in this way, the passenger can recognize which door is moving or is moving.

Further, as shown in FIG. 2, the door moving on the third door passage 13 may be thicker than the door moving on the first door passage 11 or the second door passage 12. That is, the thickness W3 of the third door 3 may be thicker than the thickness W1 of the first door 1 and the thickness W2 of the second door. The thickness of the lower part of the third door 3 including the bottom surface is not limited to the illustrated example, and is thicker than the thickness of the lower part of the first door 1 and the second door 2 including the bottom surface. I just need it. With such a configuration, the third door 3 can stably maintain an independent state as compared with the first door 1 and the second door 2.

Further, as shown in FIG. 19 and the like, the length H3 of the portion of the support plate 70 provided in the door moving on the third door passage 13 to be inserted into the groove g is on the second door passage 12. It is preferable that the length H2 of the portion of the support plate 70 provided in the moving door to be inserted into the groove g is longer. Further, the length H2 of the portion of the support plate 70 provided in the door moving on the second door passage 12 to be inserted into the groove g is the support plate provided in the door moving on the first door passage 11. It is preferable that the length of the portion of 70 to be inserted into the groove g is longer than the length H1. The length H1 and the length H2 may be the same. Further, the groove g may have a length corresponding to the support plate 70. With such a configuration, the third door 3 can stably maintain an independent state as compared with the first door 1 and the second door 2.

Further, as shown in FIG. 2, the first door 1 at the first reference position and the second door 2 at the second reference position are partly in the direction in which the edge PE of the platform P extends. It is good if they overlap. Further, it is preferable that the second door 2 at the second reference position and the third door 3 at the third reference position partially overlap each other in the direction in which the edge PE of the platform P extends.

For example, when a passenger inside the platform P touches the first door 1 or pushes the first door 1, the first door 1 receives a load on the second door 2 side. Will be. As a result, when the first door 1 is displaced toward the second door 2, the second door 2 receives a load on the third door 3 side by the first door 1. Similarly, when a passenger inside the platform P touches the second door 2 or pushes the second door 2, the second door 2 receives a load on the third door 3 side. It will be. As a result, when the second door 2 is displaced toward the third door 3, the third door 3 is loaded by the second door 2.

Even when a load is applied from the inside of the platform P in this way, the load is absorbed by the third door 3, so that the first door 1 and the second door 2 are in a stable and independent state. Can be maintained. Further, since the third door 3 which is easily loaded from the inside of the platform P has a configuration capable of maintaining a stable and independent state as described above, the strength of the gate device 100 as a whole is improved and each door falls over. Equalization is suppressed.

In the present embodiment and the modified example, an example in which three door passages are provided is shown, but the present invention is not limited to this, and four or more door passages may be provided. Further, in the present embodiment and the modified example, an example in which all the doors included in the gate device 100 are movable has been shown, but the present invention is not limited to this, and in a part of the extending direction of the edge PE of the platform P. , A board or the like that regulates passengers getting on and off the railway vehicle T may be fixedly provided on the platform P.
