Then, the guide groove of each of the guide members 30 is provided with a moving surface 30a which is inclined with respect to the vertical direction while rolling the rolling surface of the wheel 29b of the door roller 29 to move the door roller 29.

The actuator 16 shown in FIG. 4 is provided as a pneumatic cylinder mechanism that is operated by supplying and discharging compressed air, and is configured as a first actuator in the present embodiment to configure a pair of pedals. 14 is driven toward the outer side in the vehicle width direction of the railway vehicle 100 and protrudes from the side of the railway vehicle 100. Then, in the present embodiment, the actuator 16 is provided as a direct drive type actuator, and both end portions thereof are attached to the respective spring support members (27a, 27b) or the respective foot plates directly or via other members. (14a, 14b). Thereby, the actuator 16 is configured to be driven and used to separate the pair of foot plates 14 from each other. Further, both end portions of the actuator 16 (that is, the end portions on the cylinder bore side and the end portions on the rod side) are supported on the front end sides of the pair of step plates 14 in the protruding direction.

In the present embodiment, the case where the actuator 16 as the first actuator is configured as a pneumatic cylinder mechanism will be described as an example, but this is not the case. The actuator 16 as the first actuator may be configured as a hydraulic cylinder mechanism, an electric cylinder mechanism, a linear motor mechanism, and a mechanism including a rotary motor, a rack, and a pinion.

Next, the operation of the vehicle pedal device 1 will be described. The vehicle pedal device 1 is fixed to a storage space below the door opening 102 of the railway vehicle 100 via the pedal base 13 and is provided on the railway vehicle 100 side. Then, the actuator 16 is actuated while the pair of footboards 14 are in the storage position, and the pair of footboards 14 are protruded toward the protruding position from the storage position toward the outer side in the vehicle width direction.

FIG. 8 is a plan view showing the pedal device 1 for a vehicle in a state in which the pair of footboards 14 protrude from the storage position toward the protruding position. The actuator 16 that protrudes from the storage position (the state shown in FIGS. 4 to 7) toward the protruding position (the state shown in FIG. 8) is operated by a control device (not shown). The command is started by supplying compressed air to the actuator 16 from a compressed air supply source (not shown). At this time, the actuator 16 is actuated such that the rod protrudes outward from the cylinder barrel to drive the pair of foot plates 14 apart from each other.

With the operation of the actuator 16, the other end side of the pedal link 11b rotatably supported via the rotating shaft 26a is moved together with the foot board 14a by the footrest 14a, and the end side of the pedal link 11b is moved. The first guide portion 22b is restricted by the rotation shaft 24b, and the one end portion side is moved in a direction parallel to the opening width direction of the door opening 102. Similarly, the other end side of the pedal link 11a rotatably supported via the rotating shaft 26b is moved together with the foot board 14b by the foot board 14b, and the movement of one end side of the pedal link 11a is received via the rotating shaft 24a. The first guide portion 22a is limited to move in the direction parallel to the opening width direction of the door opening 102.

Further, in the above-described operation, the pedal link 11a is oscillated by being pivotally supported by the fulcrum of the pedal block 12 via the rotating shaft 19a, and the pedal link 11b is rotatably supported by the pedal via the rotating shaft 19b. The fulcrum of the block 12 is swung as a center. Then, the pedal block 12 that is restricted in the moving direction by the second guide portion 23 via the guide shaft 25 is horizontally moved in a direction orthogonal to the opening width direction of the door opening 102. At this time, the pedal block 12 will move toward the outer side in the vehicle width direction of the railway vehicle 100.

By actuating the pair of footboards 14, the pair of pedal links 11, and the pedal block 12 as described above, the pair of footboards 14 are separated from each other while being separated from each other in the direction parallel to the opening width direction of the door opening 102. The position (toward the outer side of the railway vehicle 100 in the width direction of the vehicle) protrudes. Then, the slide plate 15 slidably and movably supported by the guide mechanisms (17, 18) is slid with respect to the pair of step plates 14 with respect to the pair of step plates 14 Slide to move. Thereby, the slide plate 15 protrudes toward the outer side in the vehicle width direction of the railway vehicle 100 together with the pair of footboards 14 at a position where the pair of the footboards 14 are separated from above and below. At this time, since the slide plate 15 is elastically supported by the pair of foot plates 14 by a plurality of coil springs (28a, 28b), it is supported between the pair of foot plates 14 in a state of being aligned with the center.

When the vehicle pedal device 1 is actuated as described above, the pair of footrests 14 are positioned at the protruding positions, and the vehicle pedal device 1 is brought into the state shown in FIG. Then, the gap between the railway vehicle 100 and the platform 103 is blocked by the pair of footboards 14 and the slide plate 15 (see FIGS. 3 and 8).

On the other hand, according to an instruction from a control device (not shown), when the compressed air is discharged from the actuator 16, the actuator 16 is actuated in the opposite direction to the above-described operation direction to retract the rod toward the cylinder bore. Then, the actuator 16 is actuated in the opposite direction to the above-described operation direction, thereby causing the pair of footboards 14, the slide plate 15, the pedal block 12, and the pair of pedal links 11 to operate in opposition to the above. The pair of footboards 14 return to the storage position from the protruding position while approaching each other.

Then, in a state where the pair of footrests 14 are returned to the storage position, the slide plate 15 is disposed at a position separated from the pair of the footboards 14 and the vehicle pedal device 1 is housed on the railway vehicle 100 side. Therefore, in the state of being housed on the railway vehicle 100 side, the length of the vehicle pedal device 1 in the direction parallel to the opening width direction of the door opening 102 (the length dimension shown by the double arrow C1 in FIG. 1) The length dimension is smaller than the opening width of the door opening 102 (the length dimension shown by the double arrow B in Fig. 1). Thereby, it is possible to reduce the size of the storage space of the vehicle pedal device 1 in the state of being housed on the railway vehicle 100 side.

In the above-described embodiment, as shown in FIG. 3, in a state in which the pair of footboards 14 are in the protruding position, the front end sides of the pair of footrests 14 are protruded above the platform 103, although they are provided with The form of the vehicle pedal device 1 will be described as an example, but this is not the case. As shown in FIG. 9, the front side of the pair of footboards 14 may be brought into contact with the upper end portion of the platform 103 in a state where the pair of footboards 14 are in the protruding position, and the vehicle pedal device 1 may be provided.

In the case where the vehicle pedal device 1 is provided at the position shown in FIG. 9, if the track of the railway vehicle 100 is a straight platform 103, any of the foot plates (14a, 14b) are as shown in FIG. It protrudes in a direction parallel to the vehicle width direction, and abuts against the upper end portion of the platform 103 from the front end side thereof. However, in the portion where the rail of the railway vehicle 100 is bent, the pair of footboards 14 are oscillated in a state of being swung relative to the pedal base 13 with respect to the platform 103 provided so as to be curved along the curved rails. Connected to the upper part of the platform 103.

FIG. 10 is a plan view showing a state in which the front end side abuts on the upper end portion of the platform 103 in a state where the pair of footboards 14 are swung relative to the pedal base 13 in the protruding position. In the vehicle pedal device 1, the pedal block 12 that rotatably supports the fulcrum of each of the pedal links (11a, 11b) that is swung with the actuation of the actuator 16 is rotatably supported by the pedal base 13. Therefore, as shown in FIG. 10, the fulcrum position of each pedal link (11a, 11b) can be moved in the rotation direction of the pedal block 12 with respect to the rotation center of the pedal block 12. Thereby, the pair of footrests 14 can be swung via the pair of pedal links 11 centering on the center of rotation of the pedal block 12.

Therefore, the vehicle pedal device 1 can also make a pair of steps even when the pair of foot plates 14 are used to abut against the platform 103 provided so that the edge portion is curved along the curved track. The foot plate 14 is swung along the curved surface of the platform 103 to abut. Therefore, even when the platform 103 is bent, the gap 104 between the railway vehicle 100 and the platform 103 can be surely blocked.

As described above, according to the present embodiment, it is possible to provide the vehicle pedal device 1 in which the storage space can be reduced in a state of being housed on the railway vehicle 100 side.

Further, according to the pedal device 1 for a vehicle, the actuator 16 is directly driven to separate the pair of foot plates 14 from each other, and the pair of pedal links 14 are actuated to cause the pair of foot plates 14 to face each other. The prominent position is prominent. Then, since the direct drive type actuator 16 is supported on the front end side in the protruding direction with respect to the pair of foot plates 14, the actuator 16 will become the vehicle disposed in the railway vehicle 100 in the state of the protruding position. The state outside the width direction. Therefore, the vehicle pedal device 1 is held in the state of the railway vehicle 100, and the maintenance operation of the actuator 16, which is a drive mechanism, can be performed. Therefore, the vehicle pedal device 1 that has been miniaturized in the storage space can be further improved in maintainability.

Further, according to the vehicle pedal device 1, as described above, the pedal block 12 that rotatably supports the fulcrum of each of the pedal links (11a, 11b) is rotatably supported by the pedal base 13, and the pair of pedals 14 are provided. Can swing. Therefore, even when the pair of footboards 14 are used to abut against the platform 103 provided in such a manner that the edge portions are curved along the curved rails, the pair of stepping boards 14 can be caused along the platform 103. The curved surface oscillates to abut. Therefore, even when the platform 103 is bent, the gap between the railway vehicle 100 and the platform 103 can be surely blocked.

Further, according to the vehicle pedal device 1, in the guide mechanism (17, 18), the door roller 29 that is rotated by the rotation shaft 29a that is inclined with respect to the vertical direction is moved by the movement surface 30a that is inclined with respect to the vertical direction. The slide plate 15 is slidably moved relative to the pair of step plates 14. Therefore, the smooth movement of the slide plate 15 can be easily achieved while the load from the passenger can be stably supported when the passenger walks on the slide plate 15 which is protruded between the pair of the foot plates 14.

Further, the pedal device 1 for a vehicle is a structure in which the slide plate 15 that slides with respect to the pair of footboards 14 is supported by each of the foot plates (14a, 14b) via coil springs (28a, 28b) as elastic members. . Therefore, in a state where the pair of footboards 14 protrude from the storage position toward the protruding position, the slide plate 15 can be supported by the center side between the pair of the footrests 14 in a state of being aligned with the center by a simple mechanism. Further, in the protruding position, since the slide plate 15 is aligned toward the center side between the pair of foot plates 14, the gap between the pair of foot plates 14 can be efficiently blocked by the small slide plate 15.

Further, according to the vehicle pedal device 1, the pair of step plates 14 are provided with a dimension that is parallel to the opening width direction of the door opening 102, and becomes smaller toward the end portion side of the railway vehicle 100 on the inner side in the vehicle width direction. section. Therefore, it is possible to further reduce the size of the storage space of one of the storage positions to the footboard 14. On the other hand, the end side of the pair of footrests 14 on the inner side in the vehicle width direction is located below the body of the railway vehicle 100 even at the protruding position. Therefore, in the protruding position, it is also possible to prevent the space for the passenger to walk from becoming narrow.

As described above, even in the vehicle pedal device 1 in which the actuator 32 as the first actuator is provided, the same effect can be achieved in the same manner as the vehicle pedal device 1.

Furthermore, if it is not necessary to perform a swing operation with respect to the pedal base of the pair of footboards, the pair of footrests can be directly driven in the vehicle width direction of the railway vehicle to directly drive the pair of pedals. The first actuator of the type corresponds to a pedal device for a vehicle in which the respective footrests are provided. In this case, the end of one end side of each of the first actuators may be attached to the end portion of each of the foot plates in the vehicle width direction, and the end portion of the other end of each of the first actuators may be configured. Installed on the body of a railway vehicle.

(3) In the above embodiment, the sliding plate provided as the rectangular and flat member is guided by the guiding mechanism to guide the sliding movement direction, and the elastic member is supported by the pair of the tread plates as an example. However, the structure of the sliding plate is not limited to the form exemplified in the above embodiment, and various modifications can be made and implemented. Fig. 13 is a schematic view showing a pedal device 1c for a vehicle according to a modification. In addition, FIG. 13 is a plan view schematically showing the vehicle pedal device 1c, and only a pair of the footboard 14 and the slide plate 33 are shown. 13(a) shows a state in which the pair of footboards 14 are in the storage position, and FIG. 13(b) shows a state in which the pair of footrests 14 are in the protruding position. In addition, the pair of footboards 14 and one of the pair of pedal links, the pedal block, the pedal base, and the first actuator, which are not shown, are configured in the same manner as the vehicle pedal device 1 of the above-described embodiment. Therefore, the description is omitted.

As shown in FIG. 13, the slide plate 33 is configured to include a first plate 33a and a second plate 33b. The first plate 33a is formed in a rectangular tubular shape, and an end portion 34a is fixed in a cantilever manner with respect to one of the pair of foot plates 14, that is, the foot plate 14a. Then, the end portion on the opposite side of the end portion 34a of the first plate 33a is opened in a tubular shape toward the side of the footrest 14b.

On the other hand, the second plate 33b is fixed in an cantilever manner with the end portion 34b with respect to the other of the pair of foot plates 14, that is, the foot plate 14b. The second plate 33b is disposed such that its front end side is slidably inserted into the inner side of the first plate 33a. Then, in the storage position shown in Fig. 13 (a), the second plate 33b is disposed so as to be inserted into the first plate 33a from the end portion 35 on the opposite side from the end portion 34b to the intermediate portion. The shape of the inside. In addition, the second plate 33b is formed so as to be entirely inside the cross-section of the first plate 33a, and is formed in a rectangular tubular shape. At this time, the first plate 33a and the second plate 33b are configured in a nesting shape of a double cylinder.

Further, when the pair of step plates 14 are moved toward the protruding position from the storage position, the slide plate 33 moves so that the intermediate portion of the second plate 33b inserted into the first plate 33a is exposed from the first plate 33a. Thereby, in the protruding position, the area between the pair of footboards 14 is arranged in a state in which the slide plate 33 is stretched.

According to the vehicle pedal device 1c, the slide plate 33 is constituted by the first plate 33a and the second plate 33b which are fixed in a cantilever manner to the respective foot plates (14a, 14b), and the first plate 33a is opposed to the pair of steps One of the leg plates 14 is slidably moved, and the second plate 33b is slidably moved relative to the other of the pair of tread plates 14. Then, in a state in which the pair of footboards 14 are in the storage position, the second plate 33b is exposed from the first plate 33a and the slide plate 33 is extended, and the second plate 33b is in a state where the pair of footboards 14 are in the storage position. The state in which it is inserted into the inside of the cylindrical first plate 33a is closely accommodated. Therefore, in a state in which the pair of footboards 14 are in the storage position, the size of the slide plate 33 can be reduced.

(4) In addition to the first actuator that drives the pair of footboards so as to protrude toward the outer side in the vehicle width direction of the railway vehicle, the first step of driving the pedal block so as to be rotatable may be further provided. 2 Actuator pedal device for vehicles. FIG. 14 is a plan view showing the vehicle pedal device 1d in which the second actuator 37 is provided in addition to the first actuator 36, and shows the vehicle pedal device 1d in a state in which the pair of the foot plates 14 are in the storage position. In the description of the vehicle pedal device 1d according to the modification of the above-described embodiment, the same components as those of the vehicle pedal device 1 of the above-described embodiment are denoted by the same reference numerals, and their description will be omitted. Only the configurations of the first actuator 36 and the second actuator 37 which are different from the above-described embodiment will be described.

In the vehicle pedal device 1d according to the modification shown in Fig. 14, the first actuator 36 is provided as a direct drive type actuator. Then, the end portion of the one end side of the first actuator 36 is supported by the pedal base 13 or the body of the railway vehicle 100, and the end portion of the other end side of the first actuator 36 is rotatably supported. Guide the shaft 25. By the first actuator 36, the pair of footboards 14 are driven to protrude toward the outer side in the vehicle width direction of the railway vehicle 100.

The second actuator 37 is configured as a pneumatic cylinder mechanism, a hydraulic cylinder mechanism, an electric cylinder mechanism, a linear motor mechanism, a mechanism including a rotary motor, a rack and a pinion, and the like, and is a direct drive type actuator. Settings. Then, the end portion on the one end side of the second actuator 37 is rotatably supported by the pedal base 13 or the body of the railway vehicle 100, and the end portion of the other end side of the second actuator 37 is rotated. The rotating shaft 19a is movably supported. Thereby, the second actuator 37 is configured to allow the pedal block 12 to be driven to rotate.

Further, in the present modification, the configuration in which the second actuator 37 is supported by the pedal base 13 or the main body of the railway vehicle 100 and the rotating shaft 19a will be described as an example, but this is not the case. For example, the second actuator 37 may be in the form of being supported by the pedal base 13 or the body of the railway vehicle 100 and the rotating shaft 19b. Further, a plurality of second actuators 37 may be provided. At this time, for example, one of the second actuators 37 is supported by the pedal base 13 or the main body of the railway vehicle 100 and the rotating shaft 19a. Then, the other second actuator 37 is supported by the pedal base 13 or the body of the railway vehicle 100 and the rotating shaft 19b.

Fig. 15 is a plan view showing the pedal device 1d for a vehicle in a state in which the pair of footboards 14 are in a projecting position. In the vehicle pedal device 1d, when the pair of footboards 14 are protruded, the elongation stroke of the first actuator 36 and the elongation of the second actuator 37 are made in accordance with a command from a control device (not shown). The stroke is controlled in different ways. Therefore, as shown in FIG. 15, the pedal block 12 can be rotated by the second actuator 37, and the pair of footrests 14 can be controlled by swinging the center of rotation of the pedal block 12.

Further, various aspects can be selected as to the control mode at the time of the protruding operation of the pair of footboards 14. For example, when the pair of footboards 14 protrude toward the platform 103 provided by bending the edge portion along the curved track, the first actuator 36 and the second actuator 37 may be selected only in advance. The set extension strokes are respectively protruded to control the form in which the pedal block 12 is rotated. At this time, the predetermined extension strokes of the first actuator 36 and the second actuator 37 are set as different stroke amounts, and the pair of footboards 14 are swung in a predetermined swing angle set in advance. The status is highlighted.

Further, in the case of the protrusion operation of the pair of footboards 14, as another control mode, a configuration may be adopted in which the measurement platform between the platform 103 and the footboards (14a, 14b) is provided at the end portions of the footboards (14a, 14b). The distance sensor of the gap size controls the actuation of the first actuator 36 and the second actuator 37 in accordance with the curved shape of the platform 103. At this time, the distance sensor measures the distance between the platform 103 and the footboards (14a, 14b). Then, when the positional relationship between the pedal device 1d for the vehicle and the platform 103 is the case of the form shown in FIG. 3 and the case of the form shown in FIG. 9, the docking station 103 and the footboard (14a, by the distance sensor) The distance between 14b) makes the measurement different.

In the case of the form shown in FIG. 3, that is, when the pair of footboards 14 are in the projecting position, the front end side is provided above the platform 103 so as to be in the form of the vehicle pedal device 1d. The above distance sensor measures the size of the gap below the footboards (14a, 14b). That is, the distance between the step board (14a, 14b) and the upper surface of the platform 103 below it is measured. On the other hand, in the case of the form shown in Fig. 9, when the pair of footboards 14 are in the projecting position, the vehicle is provided such that the front end side thereof and the edge portion on the upper end side of the platform 103 protrude substantially at the same height. In the case of the form of the pedal device 1d, the size of the gap in the protruding direction of the footboards (14a, 14b) is measured by the above-described distance sensor. That is, the distance between the front end portion of the foot board (14a, 14b) and the end surface of the edge portion on the upper end side of the platform 103 is measured.

In addition to the first actuator 36 that protrudes the pair of footboards 14 toward the outside of the railway vehicle 100, the second actuator 37 that rotates the pedal block 12 is further provided in the vehicle pedal device 1d. Therefore, the first actuator 36 can be used to swing the pair of the tread plates 14 while the second actuator 37 actively swings the pair of the tread plates 14 around the center of rotation of the pedal block 12 control. Therefore, when the pair of footboards 14 protrude from the platform 103 provided with the edge portion curved along the curved track, the pair of footboards 14 can be controlled to actively swing along the curved surface of the platform 103. Therefore, even when the platform 103 is bent, the gap between the railway vehicle 100 and the platform 103 can be surely blocked.

Further, according to the vehicle pedal device 1d, since the pair of footrests 14 can be actively swung, the pair of the footboards 14 can be swung along the curved surface of the platform 103 regardless of the installation position of the vehicle pedal device 1. In other words, the vehicle pedal device 1d is not limited to being disposed such that the pair of foot plates 14 are positioned at substantially the same height as the edge portion of the platform 103, even if the pair of foot plates 14 are protruded above the platform 103. In the case of the vehicle pedal device 1d, the pair of footboards 14 can also be swung along the curved surface of the platform 103.

Further, according to the vehicle pedal device 1d, the direct drive type actuators (36, 37) are disposed on the pedal base 13 side or between the main body side of the railway vehicle 100 and the pedal block 12 side. Therefore, the actuation stroke of the first actuator 36 and the second actuator 37 can be set to be short. Therefore, in the vehicle pedal device 1d, the arrangement space in the longitudinal direction of the first actuator 36 and the second actuator 37 can be reduced in size.
