Description

  The present invention relates to a through hinged door support structure for a railway vehicle, and is particularly suitable for a frontal shape having a streamline shape.

  When the railway vehicle is the leading vehicle or the last vehicle, a through hinged door may be attached to the front portion of the vehicle body (the front portion of the vehicle body or the rear surface portion of the vehicle body) so as to be able to be opened and closed as an exit during emergency evacuation. And such an exit has the minimum opening width prescribed | regulated by the law, and in order to ensure the minimum opening width, it is necessary to open and close a penetration hinge door largely.

  By the way, in recent years, emphasizing design, the front shape of the leading vehicle or the tail vehicle is often a streamlined shape. In that case, the part which provides a penetration door becomes a streamline shape, and a penetration hinge forms a part of said streamline shape.

  In this way, when the through hinged door forms a part of a streamline shape, it is difficult to form a sliding door or a revolving door that draws a simple flow line during opening and closing operations. The door is often opened outside the vehicle body by a link mechanism and moved to the inside of the vehicle body when closed and fits into the opening, thereby eliminating the step difference from the vehicle body outer surface). In the case of such a plug door, since the through hinged door is a heavy article of about 100 kg, the following structure has been adopted so far.

  (i) The upper and lower guide rails are provided on the floor near the front wall of the vehicle body and the upper part of the door to restrict the flow line of the hinged door, and the weight is supported by the lower guide rail on the floor (see, for example, Patent Document 1). .

  (ii) Attach links above and below the hinged door.

  (iii) Attach the link to the upper and lower parts of the hinged door and attach the linear guide to the hinged door.

JP 2002-331928 A

  In the case of (i), since guide rails are provided on the upper and lower sides, the number of parts increases, and it takes time to mount and adjust.

  In the case of (ii), the number of parts is reduced, but it takes time to mount and adjust.

  In the case of (iii), the number of parts is between (i) and (ii), but the cost of the linear guide attached to the hinged door is high.

  An object of the present invention is to provide a through hinged door support structure for a railway vehicle that has a small number of parts and can reduce the time required for installation and adjustment of the through hinged door.

  According to a first aspect of the present invention, a through-passage opening is formed in the front portion of the vehicle body, and the through-passage opening is closed by a through-opening door through a link mechanism that operates a substantially parallel link mechanism. A through-carved door support structure for a railway vehicle, wherein the vehicle body has a column member extending in a vehicle vertical direction on the vehicle body inward side of the through-passage opening, and the link mechanism has one end with respect to a lower part of the through-open door The first and second open / close links are rotatably attached so that the other end portion of each of the other end portions of the column member is parallel to and shifted from the column member, and the through door is the link The mechanism is configured to be opened and closed while maintaining the direction when the through-passage opening is closed.

  In this case, the end portions of the first and second opening / closing links are attached to the lower part of the through hinged door and the column member on the vehicle body inner side of the through passage opening so that the axis of the rotating shaft is displaced. Therefore, without increasing the number of parts, the time required for the installation and adjustment of the through door is reduced, and the through door is opened and closed while maintaining the orientation when the through passage is closed. Can be.

  In particular, since the first and second opening / closing links are provided for the lower part of the through hinged door, the dead space produced by the lower part of the front part of the vehicle body including the through hinged door protruding forward is effectively utilized, First and second opening / closing links can be arranged.

  According to a second aspect of the present invention, the pillar member is a through-pass pillar that is provided on the inner side of the through-passage opening and extends in the vehicle vertical direction, and has a mounting reference surface on the through-pass pillar. Preferably, a side mounting seat is attached, and the other end portions of the first and second opening / closing links are rotatably attached to the mounting reference surface of the vehicle body side mounting seat.

  In this way, it is possible to use the through-pass pillars originally provided in the vehicle body, which is advantageous in reducing the number of parts. Although the through-hole column tends to have a relatively large manufacturing error with respect to the manufacturing tolerance of the through-channel column, the vehicle body side mounting seat (the first and second opening / closing links) Since the other end portions of the first and second opening / closing links are respectively attached to the reference mounting surface (for example, a vertical surface) of the vehicle body side mounting seat, the first and second opening / closing links are respectively attached. The position adjustment operation of the rotation center on the other end side becomes easier.

  According to a third aspect of the present invention, the through hinged door is provided with a hinged door mounting seat having a mounting reference surface on the inner side of the vehicle body, and the first and second mounting doors on the mounting reference surface of the hinged door mounting seat. It is desirable that one end of the opening / closing link is rotatably attached.

  If it does in this way, one hinged door side installation seat is attached to the vehicle body inward side of a penetration hinged door, and the one end part of the 1st and 2nd opening-and-closing link with respect to the attachment reference plane (for example, vertical surface) of the hinged door side attachment seat Since each of the doors is attached, the center of rotation of the first and second open / close links can be easily adjusted regardless of the size of the manufacturing error relative to the manufacturing tolerance of the through-hole column. become. By being manufactured in this way, before the vehicle body side mounting seat, the hinged door side mounting seat, the first and second opening / closing links, and the rotary shafts of the respective opening / closing links are attached to the vehicle body and the through hinged door, in advance. Since the device can be assembled and the operation can be confirmed, it is possible to manufacture a device with high assembly accuracy with less adjustment after mounting.

  In these cases, as described in claim 4, one of the first and second opening / closing links has a longer length in the vertical direction of the vehicle than the other opening / closing link, and has a large plate thickness. It is preferable.

  In this way, the load of the through hinged door can be stably supported mainly by one opening / closing link, and the other opening / closing link can be supported so that the through opening door does not tilt. It is advantageous for ensuring the sealing performance in the closed state.

  In this case, as described in claim 5, the first and second opening / closing links can be arranged vertically.

  In this way, the structure is simple because it is only arranged up and down.

  The structure according to claim 6, wherein an opening is provided at an intermediate portion in the vertical direction of the one opening / closing link, and the other opening / closing link is rotatably attached using the opening of the one opening / closing link. It can also be.

  In this way, the other opening / closing link is rotatably attached using the opening of the one opening / closing link, so that the downsizing can be achieved in the vertical direction.

  According to a seventh aspect of the present invention, it is desirable that the rotating shaft at each end of the first and second opening / closing links is rotatably mounted via an oil-containing bearing (oilless bearing).

  In this way, even if the weight of the penetrating hinge door is heavy, the penetrating hinge door can be smoothly opened and closed, and maintenance can be omitted for a long period of time. Ordinary ball bearings can also be used.

  In the present invention, the ends of the first and second open / close links are attached to the lower part of the through hinged door and the column member on the vehicle body inner side of the through passage opening so that the axis of the rotary shaft is displaced. Therefore, without increasing the number of parts, the time required for installation and adjustment of the through door is reduced, and the through door is opened and closed while maintaining the orientation when the through passage opening is closed. Can be.

It is explanatory drawing of the modification of a link mechanism.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, since the front part of the leading vehicle and the front part of the last vehicle have the same structure except for the orientation, in the following description, the through hinged door support structure in the front part of the leading vehicle will be described.

  FIG. 1 is a schematic plan view of a leading vehicle that employs a through-gate door support structure for a railway vehicle according to the present invention, FIG. 2 is a front view of the through-passage opening as viewed from the outside of the vehicle, and FIG. 4 is a front view of the through-passage opening as seen from the room, and FIG. 5 is a cross-sectional view taken along line BB in FIG.

  As shown in FIGS. 1 to 5, a through-passage opening 1 a is formed at a central position in the left-right direction of the vehicle in the front portion of the vehicle body 1 of the leading vehicle. The through-pass pillars 2A and 2B extending in the vertical direction are provided. A through-opening door 4 is rotatably supported via a link mechanism 3 that performs the operation of a substantially parallel link mechanism at a lower portion of the through-passage opening 1a with respect to the left through-pass post 2B when viewed from the front side outside the vehicle body 1. Is closed so that it can be opened and closed. That is, the through door 4 is opened and closed while maintaining the direction when the through passage opening 1a is closed. A window portion 4a is formed in the upper part of the through-opening door 4 side by side with the window portion 1b on the vehicle body side.

  As shown in FIGS. 2 and 3, the front portion of the vehicle body 1 has a streamline shape in which the lower part including the through hinged door 4 protrudes forward. More specifically, it has a streamline shape that gradually protrudes forward from the upper part toward the lower part and retreats backward from the middle of the lower part. That is, the lower part of the front part is a protruding part bent in a U-shape in a vertical cross section, and the through hinged door 4 also corresponds to this protruding part (the part protruding most forward is indicated by 4b). In this projecting portion, the through hinged door 4 is supported by the link mechanism 3 so as to be openable and closable. In FIGS. 2 to 4, L is the floor surface.

  As shown in FIGS. 6 to 8, the link mechanism 3 includes upper and lower open / close links in which one end portion is rotatably attached to the lower portion of the through hinged door 4 and the other end portion is rotatably attached to the through passage column 2 </ b> B. 3A and 3B (first and second open / close links), and are attached so that the rotation axis (rotation center) of each end of the upper and lower open / close links 3A and 3B is shifted.

  A latching device 9 is provided between the through-passage pillars 2A and 2B at four positions on the top and bottom, left and right of the through-opening door 4 so that the through-opening door 4 can reliably close the through-passage opening 1a. Reference numeral 10 denotes a handle provided in the through hinged door 4.

  Each of the upper and lower opening / closing links 3A and 3B has a plate-like shape having a dogleg shape in plan view. The lower opening / closing link 3B that mainly receives the weight of the through hinged door 4 is longer in the vehicle vertical direction and thicker than the upper opening / closing link 3A. The shape of the two open / close links 3A and 3B is changed in this way because the load of the through-opening door 4 that does not shake so much is mainly supported by the lower open / close link 3B to increase the plate thickness and increase the strength rigidity. In order to stably support the through hinged door 4 so as not to tilt with the opening / closing link 3A, the length in the vehicle vertical direction is increased. This makes it possible to support the through hinged door 4 so that it can be opened and closed in a stable state while maintaining the direction when the through passage opening 1a is closed, and to easily adjust the position of the rotation center of the through hinged door 4. This is also advantageous for securing the sealing performance with the through-passage opening 1a in a state where the through-opening door 4 is closed. On the other hand, the upper opening / closing link 3A only needs to have a function of regulating the operation as a substantially parallel link mechanism, and may be supported rotatably with the minimum strength and rigidity.

  In addition, openings 3Ba and 3Bb are formed in the lower opening / closing link 3B. The opening 3Ba is provided to reduce the weight, and the opening 3Bb is provided to avoid interference between the latch device 9 and the opening / closing link 3B when the hinged door 4 is opened.

  The through hinged door 4 is provided with frame members 6 </ b> A and 6 </ b> B extending in the vertical direction on the left and right rear sides of the front panel 5. Windshield rubber 7 is provided on the outside of the frame members 6A and 6B, and a door stop rubber 8 is provided correspondingly to the through-pass pillars 2A and 2B on the vehicle body side.

  At the lower part of the through hinged door 4, one hinged door side mounting seat 11 having a vertical surface 11 a (attachment reference surface) is attached to the center in the left-right direction, and a bearing unit is attached to the vertical surface 11 a of the mounting seat 11. 12A and 12B (including oil-impregnated bearings) are attached, and rotary shafts 14A and 14B on one end side of upper and lower opening / closing links 3A and 3B are rotatably supported. One of the bearing units 12A and 12B is provided for the rotating shaft 14A of the upper opening / closing link 3A and two are provided for the rotating shaft 14B of the lower opening / closing link 3B. Adjustment liners 13A and 13B are provided between the bearing units 12A and 12B and the mounting seat 11.

  Further, as shown in FIGS. 9A to 9D, the through-pass column 2 </ b> B is integrally formed with a mounting plate portion 2 </ b> Ba having a rectangular through-hole 2 </ b> Baa. One vehicle body side mounting seat 21 having a vertical surface 21a (mounting reference surface) extending in the vertical direction is attached to one side of the mounting plate portion 2Ba with a screw member 24 with a spacer 23 interposed therebetween. Bearing units 22A and 22B (including oil-impregnated bearings) that rotatably support the rotating shafts 15A and 15B on the other end side of the upper and lower opening / closing links 3A and 3B with respect to the vertical surface 21a of the mounting seat 21. The screw member 25 is attached through the through hole 2Baa. One of the bearing units 22A and 22B is provided for the rotating shaft 15A of the upper opening / closing link 3A, and two are provided for the rotating shaft 15B of the lower opening / closing link 3B. In addition, as shown to Fig.9 (a)-(d), several mounting hole 2Bab in which the screw member 24 is penetrated is formed in mounting plate part 2Ba. Moreover, the recessed part 2Bac which attaches the door stop rubber 8 is also formed.

  As described above, the rotating shafts on the hinged door side and the vehicle body side of the upper and lower opening / closing links 3A, 3B are respectively attached to the mounting seats 11, 21 common to the upper and lower opening / closing links 3A, 3B. Even if the adjustment work caused by the mutual manufacturing error of the through door 4 and the through passage pillar 2B occurs, the position adjustment work of the rotation center between the upper and lower opening / closing links 3A, 3B becomes easy.

  That is, the upper and lower opening / closing links 3A and 3B are attached to the lower upper and lower portions of the through hinged door 4 so that the axis (rotation centers) of the rotating shafts of the upper and lower opening / closing links 3A and 3B are parallel to each other and shifted. Therefore, without increasing the number of parts, the time required for attaching and adjusting the upper and lower opening / closing links 3A and 3B is reduced, and the through hinged door 4 closes the through passage opening 1a. It can be opened and closed while maintaining a rough orientation. As a result, the manufacturing cost can be significantly reduced, and for example, it can be manufactured at a cost less than half that described in Patent Document 1.

  The rotating shafts of the upper and lower opening / closing links 3A and 3B are attached to the mounting seats 11 and 21 via oil-impregnated bearings (not shown) so that the opening and closing operation of the through door 4 can be performed smoothly. It has been. Here, the oil-impregnated bearing (oil-less bearing) is a sleeve bearing in which oil is impregnated into a sintered metal (porous body), or a sleeve using a composite material of a resin and metal having high self-lubricity. Includes bearings.
