  Nowadays, there are demands for barrier-free railway vehicles, and it is required to widen the frontage of these sliding doors. However, since the sliding door disclosed in the technique of Patent Document 1 is of a single-opening type, it is difficult to secure the opening area. This is because it is necessary to bring the opening to the center. Since the width of the vehicle body is limited, the width of the sliding door is inevitably determined by providing a door pocket for the sliding door as shown in Patent Document 2.

  To solve this, the applicant proposed a double-sliding door. However, there is no particular problem with a double-opening sliding door that opens and closes automatically, but in the case where a manually-moving sliding door is required, usability becomes poor and a problem arises. In other words, in the case of a manual double sliding door, if one tries to open it with one hand, there is a problem that the frontage becomes narrower than that of the single sliding door structure because only one sliding door can be opened.

  Therefore, in order to solve such problems, an object of the present invention is to provide a railway vehicle including a gable sliding door that can be adapted to be barrier-free.

  In order to achieve the above-mentioned object, a railway vehicle including a gable sliding door according to an aspect of the present invention has the following features.

(1) In a railroad vehicle that includes a sliding door that is provided in a passage opening formed in the end of the railway vehicle and that is suspended by a support rail that is disposed above the passage opening, the sliding door is the left side. It is a double-opening structure having a sliding door and a right sliding door, the left sliding door and the right sliding door are connected by a wire rope in the upper part, a door guide member is provided below the left sliding door and the right sliding door, and the left sliding door or the above When one of the right-side sliding doors is opened by the passenger, the other wife sliding door is interlocked to open, and when the passenger releases the hand, the wife sliding door is biased in the closing direction. Characterize.

(2) In the railcar according to (1), when the left-side sliding door or the right-side sliding door is in an open state, a magnet for holding the position and momentum when the wife sliding door is opened or closed are provided. It is preferable to provide an air damper for killing.

  According to the aspect described in (1) or (2) above, a double-sliding sliding door is provided in the passage opening formed in the end portion of the railway vehicle, and the opening width of the passage opening is widened by the double-drawing. It is possible. By widening the width of the frontage, it is possible to contribute to making the barrier-free. By adopting both sliding doors in the railway vehicle, the opening is secured, and by using a wire rope to interlock, both sliding doors can be opened and closed with one hand. When making barrier-free, for example, when a person in a wheelchair opens the sliding door, the structure of the sliding door that cannot be opened without using both hands is inconvenient, which is a problem.

  However, since the right sliding door and the left sliding door are connected so as to be linked by a wire rope, it is possible to open and close the wife sliding door with one hand. Further, since the Tsumesdoor is hung by the support rail and the door rail is provided at the lower portion, it is possible to stably open and close the Tsumesdoor even when the railway vehicle is in operation, It is possible to improve convenience for passengers.

  Further, as described in (2), by using the air damper to reduce the opening and closing momentum of the sliding door, it is possible to prevent a loud sound or a hand from being caught. In addition to the frequent opening and closing of the sliding door, an air damper is used because a strong force may be exerted when the sliding door is opened when the railway vehicle is running. As a result, it is possible to reliably reduce the momentum of the sliding door. Furthermore, since the magnet is capable of maintaining the open or closed state of the sliding door, it is possible to prevent the sliding door from being opened or closed at the time of traveling. Due to these considerations, consideration is given to passenger safety.

A support rail 125 is arranged above the left sliding door 110a. The support rail 125 is attached to the end structure 105, and has a structure such that the left upper suspension vehicle 126a attached to the upper part of the left sliding door 110a passes over the support rail 125. That is, the left-side sliding door 110a has a top-hanging structure by the left-side upper hanging vehicle 126a. Similarly, the right-side sliding door 110b has a top-hanging structure by means of a right-side upper hanging wheel 126b.

  Further, an open side air damper 121a and a close side air damper 122a are provided above the left side sliding door 110a to absorb a shock when the left side sliding door 110a is opened and closed. A groove 127 is provided on the lower side of the left sliding door 110a, and a guide pin 128 is inserted into the groove 127 and is guided. The guide pin 128 is provided on the door pocket side. The right sliding door 110b side has the same structure, but the description is omitted. Further, as shown in FIG. 5, the mainspring 161 is attached to the base plate to which the upper rail 125 is attached. The mainspring 161 is a winding device 160 that winds the wire rope 162, and the tip of the wire rope 162 is fixed to the lower pin 163 of the left upper pulley 126a. By the winding force of the mainspring 161, the wife sliding door 110 is drawn and the wife sliding door 110 is closed semi-automatically.

And a right closed holding bracket receiver 134b.

  Since the railway vehicle 100 including the wife sliding door 110 of the present embodiment has the above-described configuration, it has the following actions and effects.

  First, as an effect of the present embodiment, it is possible to make the opening width of the passage opening 120 large. This is because the railway vehicle 100 including the gable sliding door 110 of the present embodiment is provided in the passage opening 120 formed in the gable portion of the railway vehicle 100, and by the support rail 125 arranged above the passage opening 120. In the railway vehicle 100 including the suspended sliding door 110, the sliding door 110 has a double-opening structure having a left sliding door 110a and a right sliding door 110b, and the left sliding door 110a and the right sliding door 110b are wire ropes 150 (150a, 150b) at the top. Guide pins 128, which are door guide members, are provided below the left sliding door 110a and the right sliding door 110b. When either the left sliding door 110a or the right sliding door 110b is opened, the other sliding door (the right sliding door 110b or the left sliding door 110b or the left sliding door 110b) is opened. This is because the sliding door 110a) is opened in an interlocking manner, and when the passenger releases the hand, the sliding door 110 is biased in the closing direction.

  Further, a magnet is arranged on at least one of the side facing the side structure 101 of the left sliding door 110a or the right sliding door 110b, and the open side air damper is an air damper for reducing the momentum when the wife sliding door 110 is opened or closed. It is preferable to provide 121a and the closing side air damper 122a.

  As described in the problem, the wife sliding door 110 provided on the wife structure 105 of the railway vehicle 100 needs to be provided at the central portion of the wife structure 105, and the railway vehicle 100 is required from the vehicle limit of the railway vehicle 100. There is a limit to the width. As a result, when a one-way pulling sliding door is provided, the width of the passage opening 120 is also limited in relation to the door pocket. Therefore, as in the present embodiment, it is possible to widen the passage opening 120 by separating the sliding doors to the left and right. However, there are cases where some users are required to open and close the sliding doors 110 manually rather than automatically. In this case, various measures are required.

  For example, since passengers often carry luggage in one hand, it is inconvenient unless the structure is such that one side is opened and the other side is opened. Therefore, in the present embodiment, the wire rope 150 is used for interlocking, so that when the left side sliding door 110a is opened, the right side sliding door 110b is also interlocked. Further, a guide pin 128 is provided as a door guide for use as the sliding door 110 of the railway vehicle 100, and prevents the sliding door 110 from swinging and flapping when the railway vehicle 100 is in operation.

  Further, the opening side air damper 121a (121b) and the closing side air damper 122a (122b) are configured to absorb a shock at the time of opening and closing. It is expected that when the railway vehicle 100 is in operation, for example, when the sliding door 110 is opened and closed when the railroad track approaches a curved portion, centrifugal force is applied in addition to the force generated by the opening and closing when the vehicle is stopped, which is expected to increase the momentum. It By using an air damper to cope with such a situation, the shock is properly absorbed. Many sliding doors used for buildings, etc. use a gear structure, but in the case of a gear structure, durability remains uncertain, so it is possible to handle higher forces assuming strong force is applied. By using the air damper, it is possible to appropriately reduce the momentum when the wife sliding door 110 is opened and closed.

  In addition, the left open holding metal fitting 131a and the left open holding metal fitting receiver 132a provided on the upper part of the left sliding door 110a, the right open holding metal fitting 131b and the right open holding metal fitting reception 132b provided on the upper part of the right sliding door 110b (not shown), The open state of the sliding door 110 can be maintained. The holding metal fitting is equipped with a magnet and a spring, and is set to a magnetic force such that the open state of the sliding door 110 can be maintained even when a centrifugal force is applied. Note that the wife sliding door 110 is urged to automatically return to the closed state when it is not opened to the open end.

  On the other hand, by the left closed holding metal fittings 133a and the left closed holding metal fittings 134a provided on the upper part of the left sliding door 110a, and the right closed holding metal fittings 133b and the right closed holding metal fittings 134b provided on the upper part of the right sliding door 110b (not shown), The closed state of the wife sliding door 110 can be maintained. Similarly, the magnetic force is set such that the closed state of the sliding door 110 can be maintained by the magnetic force even under the condition that centrifugal force is applied. Therefore, even when the railway vehicle 100 is in operation, it is possible to prevent the wife sliding door 110 from opening and closing without permission.

  By using the railway vehicle 100 having the wife sliding door 110 of the present embodiment, it is possible to promote the barrier-free railway vehicle 100. That is, for example, when moving in and out of the wife sliding door 110 in a wheelchair, a passage opening 120 having a wider width is required, but there is a limit in a manual sliding door, and the applicant has made it possible to obtain a passage opening more through the present invention. The structure of the railway vehicle 100 which can take 120 widely is proposed, and this is realized. As a result, it is possible to provide the railway vehicle 100 that is more convenient for passengers, and it is possible to meet the needs of users.

  Although the gable sliding door 110 of the railway vehicle 100 according to the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention. For example, the gable sliding door 110 is provided with an open side air damper 121a (121b) and a close side air damper 122a (122b), respectively, but since the gable sliding door 110 is opened and closed in conjunction with each other by the wire rope 150, the left side sliding door 110a or the right side sliding door. It does not prevent that it is placed on either side of 110b.

  The same applies to the left open holding metal fitting 131a and the left open holding metal fitting receiver 132a and the left closed holding metal fitting 133a and the left closed holding metal fitting 134a provided in the left sliding door 110a. For example, if the left sliding door 110a is provided with the left open holding fitting 131a and the left opening holding fitting receiver 132a, and the right sliding door 110b is provided with the right closing holding fitting 133b and the right closing holding fitting receiver 134b, the wire rope Since the left sliding door 110a and the right sliding door 110b are interlocked by 150, it is possible to maintain the open state and the closed state. Further, there are various methods for urging in the closing direction, and the power spring method is an example thereof.

  Further, although the guide pin 128 is used as the door guide member in the present embodiment, a door rail may be used. When a door rail is used in the lower part of the passage opening 120, a disadvantage can be considered from the viewpoint of barrier-free. However, depending on the user, it may be possible to install the railway vehicle 100 in a place where it is exposed to wind and rain. In such a case, it is preferable to provide a door rail because it has an effect of preventing water infiltration. These structures are preferably selected appropriately.
