Description

[Technical field]

[0001] The present invention relates to an attention calling device for train crew members of a railway vehicle. [Background technology]

[0002] One of the main duties of a conductor aboard a train is "door handling," which involves the conductor moving between the driver's compartment and the station platform through an entrance to the driver's compartment on the side of the train, checking safety and operating the conductor's switch, etc. Summary of the Invention [Problem to be solved by the invention]

[0003] Depending on the state in which the train was stopped, a large gap could form between the train and the platform, which could cause the conductor to fall into the gap while operating the doors.

[0004] An object of the present invention is to provide a train attendant attention drawing device capable of appropriately drawing the attention of train attendants who operate doors. [Means for solving the problem]

[0005] One embodiment of the present invention is a device for alerting railway vehicle crew members, the device including: an air nozzle provided at an entrance / exit of a crew compartment provided on the side of the railway vehicle; an air nozzle provided from the crew entrance / exit of the railway vehicle toward the outside of the vehicle; and a control device that sprays air from the nozzle at least when the passenger doors of the railway vehicle are in an open state. Effect of the Invention

[0006] According to the present invention, it is possible to appropriately alert train crew members who operate the doors. [Brief description of the drawings]

[Diagram 3] FIG. 3 is an enlarged view of a portion of the doorway shown in FIG. [Figure 4] FIG. 4 is a diagram illustrating an example of the configuration of the control device. [Diagram 5] FIG. 5 shows a time chart of the control device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] FIG. 1 is a diagram showing a side view of a portion of a railway vehicle according to an embodiment, and FIG. 2 is a diagram showing a cross section taken along line BB in FIG. 1. FIG. 3 is a diagram showing an enlarged view of a portion of an entrance / exit shown in FIG. 1. Railway vehicle 10 is a vehicle used as the leading or last car in a train formation, and has a crew compartment 15 (FIG. 2) and passenger compartments provided inside the vehicle. An entrance / exit (boarding / alighting) 11 to the crew compartment 15 is formed on the side of railway vehicle 10 (a door for opening and closing entrance / exit 11 is not shown). Crew members of the railway vehicle (conductor, driver) can travel (get on and off) between the crew compartment 15 and the outside of the vehicle (station platform 16 (FIG. 2)) through entrance / exit 11.

[0009] In addition, passenger doors 12, which are doors for passengers to board and disembark, are provided on the sides of the railcar 10. The passenger doors 12 are opened and closed by a door opening and closing device that uses compressed air and is provided on the railcar, and the opening and closing operation is operated by a crew member (e.g., a conductor). Passengers can enter and exit the passenger compartment through the passenger doors 12.

[0010] When the railcar 10 arrives at a station, the conductor descends from the entrance / exit 11 onto the station platform 16 and performs the required door operations (safety checks, operating the passenger door open / close switches, etc.). At this time, the conductor is likely to be looking into the distance, such as looking from the rear end of the railcar 10 toward the front to check on passengers getting on and off, and so may be careless about his / her feet. At some stations, the platform is curved, and a large gap may be created between the railcar 10 and the platform 16. There is a possibility that the conductor may unknowingly get too close to the railcar 10 and fall into the gap. The attention warning device according to the embodiment is configured to warn the conductor who is handling the doors to be careful about the gap.

[0011] The attention-calling device includes a nozzle 20 and a control device 21. The nozzle 20 is an air outlet, and is provided at an entrance 11 of a driver's compartment 15 provided on a side of the railcar 10. A rectangular frame 14 is fitted into a side wall 10A (FIG. 2) of the railcar 10 at the entrance 11. The nozzle 20 is provided on an inner surface 14a of the frame 14 in a state of protruding from the inner surface 14a in a state of heading toward the front or rear end of the railcar 10, whichever is closer (the rear end in the example shown in FIG. 1). However, the nozzle 20 may be provided in a state of being embedded in the inner surface 14a. With this configuration, air is ejected from the nozzle 20 toward the rear end of the railcar 10. In this embodiment, the direction of the nozzle 20 is fixed, but the direction of the nozzle 20 may be changeable at an appropriate timing (for example, in response to the boarding and disembarking of the driver using the entrance 11).

[0012] As shown in Fig. 2 and Fig. 3, the nozzle 20 is provided as follows in detail. That is, the nozzle 20 is arranged facing the outside of the railway vehicle 10 so that air is ejected outside the railway vehicle 10. Specifically, as shown in Fig. 2, the nozzle 20 is preferably arranged such that an angle θ1 between the central axis L1 of the nozzle 20 and the outer side surface 13 of the railway vehicle 10 is 10° to 30° in a plan view of the railway vehicle 10. However, it is more preferable that the angle θ1 is 15° to 25°. In this embodiment, the angle θ1 is set to 20°. In other words, when the side surface of the railway vehicle 10 and the outer edge 16a of the platform 16 (shown by a two-dot chain line in Fig. 2) are parallel, the outer edge 16a intersects with the central axis L1 at θ1.

[0013] Moreover, the nozzle 20 is preferably arranged so that air is ejected downward from the nozzle 20. Specifically, as shown in Fig. 3, in a side view of the railway vehicle 10, the nozzle 20 is preferably arranged so that an angle θ2 between the central axis L1 of the nozzle 20 and a vertical line (the inner surface 14a of the frame 14 arranged in the vertical direction) is 70° to 50°. However, it is more preferable that the angle θ2 is 65° to 55°. In this embodiment, the angle θ2 is set to 60°.

[0014] Moreover, the nozzle 20 is preferably provided at the bottom of the entrance 11. For example, the height H of the nozzle 20 is preferably arranged at a height of 40 cm or less from the entrance 11, i.e., the lower end of the frame 14. However, it is more preferable that the height H is 15 cm or more and 30 cm or less. In this embodiment, the height H is set to 25 cm.

[0015] With the nozzle 20 positioned and oriented as described above, compressed air is ejected from the nozzle 20 in a straight line in the direction of the central axis L1, so that the air (wind) hits the feet of the crew member standing near the entrance 11 to open the door. By sensing the wind hitting his / her feet, the crew member can realize that the position 40 of the crew member's feet is approaching the outer edge 16a of the platform 16. In other words, the crew member can be alerted to the approach of the outer edge 16a of the platform 16. However, the arrangement of the nozzle (direction, height, etc.) can be set as appropriate and is not limited to the above example.

[0016] Fig. 4 is a diagram showing a configuration example of the control device 21. In Fig. 4, the control device 21 includes a switch SW for opening and closing the passenger door 12, a timer relay TLR1 connected to the switch SW, a contact TLR1-a whose opening and closing operation is controlled by the timer relay TLR1, and a solenoid valve SV1.

[0017] The switch SW is provided in the driver's compartment 15 and is turned on and off by manual operation by the conductor. The timer relay TLR1 is turned on and off in conjunction with the on and off of the switch SW. The contact TLR1-a is a contact that controls the on and off of the solenoid valve SV. The solenoid valve SV1 controls the on and off of the injection of air from the nozzle 20 by opening and closing it. That is, the solenoid valve SV1 opens in conjunction with the opening operation of the passenger door 12 and supplies air to the nozzle 20. The compressed air injected from the solenoid valve nozzle 20 is diverted from the compressed air for opening and closing the passenger door 12. However, an air cylinder for the nozzle 20 may be installed. The pressure of the air injected from the nozzle 20 is, for example, 490 kPa, but may be larger or smaller than the above example as long as the conductor can be blown with a suitable wind.

[0018] 5 is a time chart showing an example of the operation of the control device. When the railway vehicle 10 stops at a station, the conductor opens the door of the entrance / exit 11 to allow passengers to disembark, confirms that it is OK to open the passenger door 12, and turns on the switch SW (time t1). Then, the passenger door 12 performs an opening operation and enters an open state. In conjunction with the opening operation of the passenger door 12, the timer relay TLR1 turns on. The timer relay TLR1 turns on the contact TLR1-a. This turns on the solenoid valve SV1 (open state), causing air to be sprayed from the nozzle 20.

[0019] Thereafter, when it is time for the railcar 10 to depart, the conductor checks that there is no abnormality near the passenger door 12 and turns off the switch SW (time t2). Then, the passenger door 12 performs a closing operation and enters a closed state. When the switch SW is turned off, the timer relay TLR1 is also turned off. However, the contact TLR1-a is turned off after a predetermined time T1 has elapsed due to residual magnetism of the timer relay (time t3). The length of the time T1 can be set appropriately, but is, for example, 15 to 30 seconds, and preferably 15 to 20 seconds. In this way, the timer relay TLR1 closes the solenoid valve SV1 after the predetermined time T1 has elapsed since the passenger door 12 was closed.

[0020] When the contact TLR1-a is turned off, the solenoid valve SV1 is turned off (closed), and air stops being ejected from the nozzle 20. The conductor enters the train through the entrance / exit 11 and closes the door. After that, the railcar 10 departs.

[0021] According to the attention warning device of the embodiment, when the conductor gets off the train through the entrance / exit and opens the passenger door 12, air is sprayed from the nozzle 20, and when the conductor's feet approach the outer edge 16a of the platform 16, the air (wind) from the nozzle 20 hits the conductor's feet, thereby alerting the conductor.

[0022] In the embodiment, air is injected not only while the passenger door 12 is open, but also continues until the time T1 has elapsed even after the passenger door 12 is closed. This allows air to be injected continuously until the conductor gets into the crew compartment 15. The configuration of the above-described embodiment can be modified as appropriate without departing from the scope of the invention. [Explanation of symbols]
