Description

  The present invention relates to a cab structure of a railway vehicle.

  Generally, a cab of a railway vehicle includes a cab 52 and a driver seat 54 as shown in FIG. Above the cab 52, there is a top board 56 on which a driving operation section, various instrument displays, and the like are arranged, and below the top board 56, a foot platform 58 is provided.

  The footrest 58 of the conventional cab 52 has a front end portion 58a, that is, an end portion on the side of the driver 1 sitting on the driver's seat 54 at the same position as the front end portion 56a of the top board 56 or a position deeper than that ( It was in the position retracted to the inside of the cab 52). This is because the footrest 58 is assumed to be used as a footrest for the driver 1 who is driving.

  In recent years, due to an increase in the number of female drivers, the number of drivers who are shorter than before has also increased. A driver with a short height may climb on the footrest 58 when sitting or standing on the driver seat 54 or adjusting the driver seat 54. However, since the footrest 58 is located behind the front end of the top plate 56 (inside the cab 52, the front side in the vehicle traveling direction), when the footrest 58 is climbed, the waist is bent and unstable. It becomes a stance.

  As a driver's cab considering the difference in body shape of the driver, for example, Patent Document 1 proposes to install a step device that can adjust the height position on the driver's cab floor. However, this step device makes it possible to adjust the height of the cab floor when the driver sits on the driver's seat, that is, the height corresponding to the footrest 58 in FIG. It is installed on the floor (foot platform 58). That is, the step platform device is installed on the inner side of the front end portion of the top plate (56) of the cab (52). Therefore, when the driver sits on the driver's seat and stands on the driver's seat with his / her foot on the platform device, the posture is also unstable with his / her waist bent.

JP 2005-324614 A

  The present invention has been made in view of such circumstances, so that even a driver with a short height can easily sit on the driver's seat without taking an unstable posture, and can also look immediately before the vehicle. It is another object of the present invention to provide a driver's cab structure that can extend from the driver's seat.

The present invention for solving the above-mentioned problems is a driver's cab structure of a railway vehicle including a driver's cab and a driver's seat, the driver's cab comprising a top board, a footrest provided below the top board, And a footrest extension plate extending from the footrest, wherein the footrest extension plate can be taken in and out of the footrest.

  In addition, the footrest extension plate may be attached to the footrest so that it can be inserted and removed by rotating about the vicinity of the front end portion on the driver seat side of the footrest. The footrest extension plate may be housed inside the footrest, and may extend the footrest by being pulled out from an end surface of the footrest on the driver seat side. In addition, the footrest extension plate is housed in a position on the floor surface where the cab is grounded and in contact with the end surface on the driver seat side of the footrest, and is drawn upward from the floor surface, thereby It is good also as extending a stand.

  In addition, the present invention for solving the above-mentioned problems is a driver's cab structure of a railway vehicle provided with a door in the vicinity of a driver's cab and a driver's seat, the door being located above the floor on which the door is installed. A footrest extension plate that can be taken in and out is provided.

  Below, the cab structure of this invention is demonstrated in detail using drawing.

  FIG. 1 is a side view conceptually showing an embodiment of the present invention. The driver's cab 10 is provided in the leading vehicle of the railway vehicle and includes a cab 12 and a driver seat 14. The left side in the figure is the traveling direction of the railway vehicle, and the driver 1 sits on the driver's seat 14 toward the driver's cab 12.

  The cab 12 has a top plate 16 in which a driving operation unit, a display unit of various instruments, and the like are arranged at an upper portion, and a footrest 18 is provided below the top plate 16. An end (front end) 18a of the footrest 18 on the driver seat 14 side is substantially on the same vertical line as an end (front end) 16a of the top plate 16 on the driver seat 14 side. A space is provided in the upper part of the footrest 18 so that the feet of the driver 1 sitting on the driver seat 14 can enter. In this embodiment, a substantially horizontal footrest 18 is provided from the driver seat 14 side toward the inner side of the cab 12, but the footrest 18 is not necessarily provided from the driver seat 14 side to the cab 12 inside. For example, the footrest 18 may be inclined from the driver seat side 14 toward the inner side of the cab 12.

  A footrest extension plate 20 is provided on a portion of the footrest 18 on the driver seat 14 side. The footrest extension plate 20 protrudes toward the driver seat 14 and extends the footrest 18 toward the driver seat 14. The footrest extension plate 20 does not have to be provided so that the upper surface thereof and the upper surface of the footrest 18 are substantially at the same height. If necessary, the upper surface of the footrest extension plate 20 is provided on the footrest 18. It can also be provided so as to be higher or lower than the upper surface. The footrest extension plate 20 only needs to extend to the driver seat 14 side from the front end portion 16a of the top plate 16, but preferably protrudes to the extent that the driver 1 puts his / her foot and stands almost vertically. It is preferable that it protrudes 75 mm or more from the front end portion 16 a of the top plate 16.

  When the driver 1 is a small person (such as a short driver), when sitting on the driver's seat 14, the driver 1 first goes up to the footrest extension plate 20 and then sits on the driver's seat 14. You can sit comfortably. According to the present invention, since the footrest extension plate 20 is provided so as to protrude to the front side of the cab 12, that is, the front end portion 16 a of the top plate 16, the driver 1 is attached to the footrest extension plate 20. When riding, it can take a posture that does not bend its waist and can sit on the driver's seat 14 in a stable posture. Similarly, when getting off the driver's seat 14, it is possible to get off with a stable posture using the footrest extension plate 20. Further, when the driver 1 with a short height extends to look just before the vehicle, he can ride on the foot extension plate 20 and extend in a stable posture.

  The height at which the footrest extension plate 20 is installed is not particularly limited, but a driver or the like having a short height can easily sit on the driver seat and can sit on the driver seat 14 in a stable posture. Considering this point, it is preferable that the footrest extension plate 20 is within a range of about 1110 mm to 1200 mm below the position of the eyes of a driver or the like who is seated. The footrest extension plate 20 may be the same height as the footrest 20, or may be lower or higher than the footrest 20.

  The footrest extension plate 20 may be fixedly provided on the driver's cab 12, but is not necessary for the driver 1 having a high height, and the driver's cab 10 is a space where the driver 1 is limited. It is conceivable that the footrest extension plate 20 gets in the way when moving. Moreover, depending on the form of the vehicle, the footrest extension plate 20 may interfere with the door opening and closing. In consideration of such points, it is preferable that the footrest extension plate 20 has a structure that can be inserted into and removed from the footrest 18 and protrudes only when necessary. As such a protruding structure, for example, a form such as lifting from the end surface of the footrest 18, pushing forward, or lifting from the floor surface can be mentioned.
