Description

  The present invention relates to a floor structure of an entrance / exit for a railway vehicle, and more particularly, to a structure of a floor portion of an entrance / exit provided on a side surface of a railway vehicle body.

Conventionally, various proposals have been made to eliminate the level difference between the floor surface of the railway vehicle entrance / exit floor and the top surface of the platform, and the gap between the two. For example, it is suggested that the step plate is raised and lowered from the vehicle side home side. (For example, refer to Patent Document 1).
Japanese Patent Laid-Open No. 2001-180483

  However, the relationship between the entrance / exit and the platform is not uniform, enormous equipment costs are required to support all vehicles and homes, and maintenance requires enormous costs and labor. To do.

  On the other hand, Article 30 of “Standards for Passenger Facilities and Vehicle Structures and Equipment Necessary for Facilitating Movement” provides provisions for passenger entrances and exits of rail vehicles, and further, the end of the steps in the car. It is specified that the steps in the vehicle can be easily identified due to a large difference in color brightness between the portion and the surrounding portion. In addition, for entry / exit in the structure and equipment of automobiles, not railcars, Article 35 states that “the step of the entrance / exit has a large difference in color brightness between its end and the surrounding area. It must be easy to identify the steps. "

  Based on these regulations, railway cars in recent years have yellow lines and plates provided on the floor of the entrance and exit so that the entrance and exit can be easily identified. It is desired.

  Accordingly, an object of the present invention is to provide a floor structure for a railway vehicle entrance / exit that can clearly identify the entrance / exit from both the passenger compartment and the platform.

  In order to achieve the above object, the floor structure for a railway vehicle entrance / exit of the present invention embeds a light source in a vehicle interior side floor portion of a passenger door provided at the entrance / exit of the railway vehicle, and a floor above the light source. It is characterized in that a hard translucent member is provided on the surface.

  Furthermore, in the railcar floor structure according to the present invention, the light source is provided at the bottom of the groove-shaped member opened upward and embedded in a transparent synthetic resin filled in the groove of the groove-shaped member. Furthermore, the light source is turned off when the passenger door is closed, flashes when the passenger door opens, lights up when the passenger door is open, and flashes when the passenger door is closed. It is characterized by.

  According to the floor structure of the railway vehicle entrance / exit of the present invention, since the floor surface inside the entrance / exit door is lit or flashing, the entrance / exit can be surely recognized by the passenger before the entrance / exit door opens, When the passengers are in the open state, the passengers can be surely recognized of the entrance. In addition, by providing a detachable hard translucent member, even if the surface is soiled or damaged by passengers getting on and off, the light source is not affected, and only the hard translucent member can be replaced. Can return to the initial state.

  Furthermore, by embedding the light source in the transparent synthetic resin, the light source part can be reliably protected and the light source can be protected from water intrusion. In addition, by turning on, blinking, and turning off the light source in accordance with the opening / closing of the passenger door, it is possible to call attention to the opening / closing operation of the passenger door without causing any distractions during traveling.

  FIG. 1 shows an embodiment of the present invention, FIG. 1 is a cross-sectional view taken along the line II in FIG. 2, FIG. 2 is a plan view showing a half of the entrance, and FIG. 3 is an example of a light emitting unit used as a light source. FIG. 4 is an explanatory view showing an example of arrangement of entrances and exits and light sources in a vehicle body of a railway vehicle.

  First, the entrance / exit 11 shown in this embodiment is provided on both sides of the deck portion 13 disposed at both ends of the vehicle body 12, and the entrance / exit door 14 having a double opening structure is provided at each entrance / exit 11. . Each entrance / exit door 14 is formed so as to open and close the entrance / exit 11 by being guided by a guide rail 15 and an upper guide (not shown) provided on the floor surface.

  The scissors 16 located outside the guide rail 15 are provided with a stopper 17 at the center in the opening width direction and two display bands 18 over the entire opening width direction. This display band 18 is provided to improve the visibility of the edge of the floor surface of the entrance 11, and an elongated member colored in a color that differs greatly in brightness from the crush 16, for example, yellow, is clogged. 16 is fitted.

  On the other hand, a light emitting unit 20 is embedded in the floor portion of the guide rail 15 that is closest to the passenger compartment side of the passenger door 14. In the light emitting unit 20, a plurality of LEDs 22 serving as light sources are arranged at predetermined intervals with respect to the longitudinal direction at the bottom of the groove-shaped member 21 that opens upward, and the LEDs 22 are filled in the grooves of the groove-shaped member 21. The lead wire 24 is pulled out from both ends of the groove-shaped member 21 while being embedded in the transparent synthetic resin 23, and a fixing portion 26 for the fixing screw 25 is provided at both ends of the groove bottom plate. The transparent synthetic resin 23 is formed so as to protrude in a rectangular cross section to the upper part of the opening of the groove-shaped member 21, and is formed so that moisture does not enter the groove-shaped member 21.

  The light emitting unit 20 is disposed in the floor so that the lower surface of the groove-shaped member 21 does not contact the upper surface of the upper frame plate 27, and a fixing screw 25 inserted through the fastening portion 26 is provided in the door lower frame portion. It is attached to a predetermined position of the vehicle body 12 by being fastened to a mounting bracket (not shown). A hard translucent member 28 is detachably provided on the floor located above the light emitting unit 20. The rigid translucent member 28 has a convex cross section, and is attached to the upper surface of the floor plate 31 with a fixing screw 30 in a state where the convex portion 28a is fitted in a slit 29a provided in the holding plate 29. .

  The light emitting unit 20 arranged in this way connects the lead wire 24 to the power supply control unit, and lights or blinks the LED 22 according to the opening / closing operation state of the passenger door 14 and the traveling position of the vehicle. Thus, by blinking, it is possible to inform that the vehicle has approached the stop station and the position and direction of the passenger door 14 that opens when the vehicle stops. Further, by turning on or blinking in conjunction with the door switch, it is possible to call attention when the passenger door 14 performs an opening / closing operation. Further, by turning on or blinking when the passenger door 14 is open, the floor surface of the entrance 11 can be recognized by the passengers in the vehicle or at the platform, and attention is paid to the platform and the platform. It is possible to more reliably recognize the gaps and steps.

  Moreover, since LED22 can be protected from external force etc. by using the light emitting unit 20 which embedded LED22 in the transparent synthetic resin 23 as a light source, it can be used in the stable state over a long period of time. Furthermore, by placing the lower surface of the light emitting unit 20 in a floating state, it is possible to prevent the light emitting unit 20 from being immersed in water, and in combination with the embedding with the transparent synthetic resin 23, the LED 22 and the wiring are damaged by moisture. Can be prevented.

  In addition, by providing the hard light-transmitting member 28 above the light emitting unit 20, it is possible to prevent the light emitting unit 20 and the transparent synthetic resin 23 from being directly damaged even when stepped on. In addition, since the hard light transmitting member 28 is attached by the restraining plate 29 and the fixing screw 30, the hard light transmitting member 28 can be easily replaced even if the upper surface of the hard light transmitting member 28 is damaged or dirty.

  In addition, the form and structure of the entrance / exit 11 and the entrance / exit door 14 etc. are arbitrary, and may be installed in one place on the vehicle body side, and may be installed in three or more places. Further, since the transparent synthetic resin 23 is protected by the hard light-transmitting member 28 when mounted on the vehicle body, a relatively inexpensive transparent synthetic resin such as an AS resin or a PS resin can be used. On the other hand, it is preferable to use a PC resin, glass, or the like for the rigid translucent member 28 so as to withstand an impact from a shoe sole, the tip of an umbrella, or the like. The transparent synthetic resin 23 and the hard translucent member 28 may be translucent or colored as long as an appropriate amount of light can be obtained. Moreover, although LED22 used as a light source can use the thing of arbitrary coloring, from the meaning to call attention, red and yellow are preferable. Furthermore, a plurality of color tone LEDs or other light sources can be combined, and can be turned on or blinking in different color tones, and the blinking interval can be set differently depending on the situation.
