Description

  The present invention relates to a sliding door device in a railway vehicle.

  Sliding doors for rail vehicles and monorail rail vehicles are provided on the side surfaces of the vehicles and on the end portions of the longitudinal ends of the rail vehicles. The sliding door of the wife part is installed in a through-passage that connects the vehicles.

  The sliding door of the wife part is a gravity type sliding door that hangs from a slanted rail so that the door pocket side is higher than the horizontal plane. It is supposed to be closed.

  According to this, electric power and air pressure for opening and closing the sliding door are unnecessary, and the apparatus can be simplified. In particular, after the sliding door closes the doorway, it is safe because it cannot be opened without power or human power.

  Since such a sliding door rides on an inclined rail, it moves up and down with the opening and closing operation of the sliding door. For this reason, in the state where the sliding door is opened, a gap is opened between the lower end of the door end side end and the floor surface of the passage. Particularly in the case of a railway vehicle, there is a cant and centrifugal force, so it is necessary to set the inclination angle of the rail to about 2 degrees. For example, in the case of a door that can move 700 mm, the gap between the floor surface and the lower end of the sliding door is 25 mm. Varies.

  If there is such a gap, the foot of a passenger wearing sandals or the like may be caught in the gap, which is not preferable. In particular, when crowded, the passenger may be pushed and the tip of the shoe may enter the gap. Also, there is a possibility that objects (empty cans, batteries, etc.) will enter the gap and the sliding door will be poorly opened and closed.

Therefore, in the gravity type sliding door that moves along the rail inclined so that the door pocket side becomes higher with respect to the horizontal direction and opens and closes the doorway, the sliding door is suspended from the rail inclined with respect to the horizontal direction. A closing plate for closing a space between the lower end of the sliding door main body and the floor surface of the sliding door is installed in the sliding door main body so as to be freely rotatable in the vertical direction by a pin on the door bottom side of the sliding door. It has been proposed that the lower end of the plate is inclined at substantially the same inclination angle as the rail, thereby eliminating a gap between the lower end of the sliding door and the floor surface (see, for example, Patent Document 1). ).
JP 2007-56487 A (paragraphs 0011 to 0014 and FIG. 6)

  In the technique described in Patent Document 1, the closing plate is installed in the main body, and can be freely rotated in the vertical direction by a pin on the door bottom side of the sliding door, and the closing plate requires a width from the door tip side to the door bottom side. It is disadvantageous in terms of weight.

  In addition, in order to attach a closing plate to a sliding door already attached to an existing vehicle as described in Patent Document 1, it is necessary to considerably modify the sliding door, and the lower guide (rail) It is also necessary to modify the vehicle side, such as reducing the width of the vehicle.

  An object of the present invention is to provide a sliding door device in a railway vehicle that prevents a passenger's feet wearing sandals from being caught in a gap between a floor surface and a sliding door without increasing the weight so much. .

  The invention according to claim 1 is a sliding door device in a railway vehicle in which a sliding door is suspended by a rail inclined so that the door pocket side becomes higher with respect to the horizontal direction, and the sliding door is opened and closed by moving along the rail. A plate-like closing member is supported on the door end side of the sliding door and on the lower side of the indoor side and the outside of the vehicle so as to be movable in the vertical direction, and the closing member is located outside the door pocket when the sliding door is fully opened. It is characterized by being.

  In this way, since the closing member supported so as to be movable in the vertical direction closes the gap between the floor surface and the sliding door, the foot of the passenger wearing sandals is sandwiched between the floor surface and the sliding door. Can be prevented. Since the closing member is located outside the door pocket when the sliding door is fully opened and the closing member is only provided on the door end side, the weight does not increase so much and it is effective in improving the existing vehicle.

  According to a second aspect of the present invention, an engaged portion that extends in the vertical direction is formed on one of the sliding door or the closing member, and an engaging member that is slidably engaged with the engaged portion is provided on the other. It can be set as the structure which has.

  In this way, since the engaging relationship between the engaged portion and the engaging member is used, the closing member can be moved in the vertical direction.

  Preferably, the engaged portion is a long hole extending in the vertical direction, and the engaging member is an engaging pin member that is slidably engaged with the long hole.

  In this way, since the engagement relationship between the long hole and the engagement pin member is utilized, the closing member can be moved in the vertical direction with a simple structure.

  According to a fourth aspect of the present invention, it is desirable that the position of the long hole is shifted in the vertical direction between the closing member on the vehicle outer side and the closing member on the indoor side.

  In this case, the position of the long hole is shifted in the vertical direction between the closing member on the vehicle exterior side and the closing member on the indoor side, so that the rigidity of the sliding door by providing the long hole is reduced. Is prevented.

  As described in claim 5, a guide member such as a guide pin that is slidably engaged with a lower end open portion of the sliding door body is provided in the vicinity of the door pocket, and a mounting plate is fixed to the guide member so that they are integrated. The closing member is preferably positioned above the mounting plate when the sliding door is fully opened.

  If it does in this way, prevention of the swing of the sliding door by a guide member can be secured, and it can prevent that a passenger's foot is pinched by a closure member.

  In this case, as described in claim 6, when the sliding door is opened, the engagement pin member may be positioned at the upper end of the long hole before the sliding door is fully opened. .

  In this way, with a simple configuration, interference between the mounting plate to which the guide member is attached and the closing member is avoided.

  In the present invention, as described above, since the closing member closes the gap between the floor surface and the sliding door, it is possible to prevent a passenger's feet wearing sandals from being caught in the gap between the floor surface and the sliding door. it can. Since it is only provided on the door end side, the weight is not increased so much.

  In particular, the closing member is positioned outside the door pocket when the sliding door is fully opened, and the closing member is only provided on the door end side, so that the weight is not increased so much and it is effective for improving an existing vehicle.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1A is a front view showing a sliding door device in a railway vehicle according to an embodiment of the present invention, FIG. 1B is a side view thereof, FIG. 2 is an explanatory diagram of opening and closing operations of the sliding door, and FIG. 4 is a front view showing the sliding door mounting structure, FIG. 4 is an enlarged view of portion A in FIG. 1B, and FIG.

  As shown in FIGS. 1 to 5, a door closing device 14 is attached to the upper portion of the wife doorway 12 and the upper portion of the door pocket 13 of the wife structure 11, and the guide rail 15 of the door closing device 14 is arranged in the horizontal direction. It inclines so that the door pocket 13 side may become high. Then, the sliding door 1 is suspended by the guide rail 15 and is opened by being pulled along one side by a human force and moved along the guide rail 15, while it is naturally closed by gravity due to the inclination of the guide rail 15. ing.

  As shown in FIGS. 6 to 9, the door sliding door 1 has a door end rubber 3 (door rubber) attached to a side edge of the door tip side extending in the vertical direction via a support member 2. On the door end side of the sliding door main body 1A, rectangular plate-like closing plates 4 and 5 are supported movably in the vertical direction on the indoor side and the lower end of the vehicle exterior, respectively. In addition, the door edge side edge part of the closing plates 4 and 5 is set as the structure which does not protrude to the door edge side from the support member 2. FIG.

  A guide pin 21 (guide member) that protrudes upward is disposed on the floor surface of the doorway 12 on the door pocket 13 side. The lower end edge of the sliding door body 1A is recessed by attaching an inverted U-shaped member 26, and the guide pin 21 is slidably engaged with the recessed portion (member 26). The wife sliding door 1 is prevented from swinging. The guide pin 21 is welded to the upper side of the rectangular mounting plate 22 in plan view so that the guide pin 21 and the mounting plate 22 are integrated, and the mounting plate 22 is attached to the floor surface on the door pocket 13 side.

  A lower rail 23 is provided on the floor surface of the doorway side of the wife doorway 12. When the sliding door 1 is closed, the recessed portion (member 26) is engaged with the lower rail 23 to prevent the sliding door 1 from swinging due to wind or the like.

  The closing plates 4 and 5 are each formed with two long holes 4a and 5a extending in the vertical direction, and the engaging pin member slidably engaged with the long holes 4a and 5a in the sliding door body 1A of the sliding door 1 6 is provided. Therefore, when the engaging pin member 6 slides in the long holes 4a and 5a of the closing plates 4 and 5, the closing plates 4 and 5 move up and down.

  Each engagement pin member 6 has a shaft portion 6a whose tip is a screw portion, and a head portion 6b having a diameter larger than the width of the long holes 4a and 5a. The engaging pin member 6 is screwed to the sliding door main body 1A, but a collar 7 having a length longer than the thickness of the closing plates 4 and 5 is fitted around the shaft portion 6a. The amount of screwing of the pin member 6 is restricted, and free elevation of the closing plates 4 and 5 is not impaired.

  And although the lower end edge of the closing plates 4 and 5 is located further below the lower end edge of the sliding door main body 1A, it engages so that it may become the protrusion amount which does not contact the attachment board 22 of the guide pin 21 at the time of the fully open door sliding door 1. The pin member 6 is regulated by the engagement relationship with the long holes 4a and 5a. In other words, the operation line S2 of the sliding door 1 is inclined along the guide rail 15 as shown in FIG. 2, but the operation line S1 of the closing plates 4 and 5 is the engagement pin when the sliding door is initially opened. Since the member 6 can move in the long holes 4a and 5a from the lower end side toward the upper end side, as shown in FIG. 2, it is substantially horizontal. Since the engaging pin member 6 reaches the upper end of the long holes 4a and 5a before the mounting plate 22 of the guide pin 21 (refer to point P in FIG. 2), thereafter, the sliding door 1 is interposed via the engaging pin member 6. The operating lines of the closing plates 4 and 5 are parallel to the operating line of the sliding door 1. When the sliding door 1 is fully opened, the lower end edges of the closing plates 4 and 5 are lifted up to the upper side of the mounting plate 22 of the guide pin 21, and the closing plates 4 and 5 do not contact the mounting plate 22.

  The closing plates 4, 5 are formed so that the indoor side closing plate 4 is longer in the vertical direction than the outer side closing plate 5, and each has a long hole at an intermediate position in the vertical direction of the closing plates 4, 5. 4a and 5a are formed. The long holes 4a and 5a have the same length, but their positions are shifted in the vertical direction between the indoor side closing plate 4 and the vehicle outer side closing plate 5. And in the state in which the closing plates 4 and 5 were attached, the lower end edges of the closing plates 4 and 5 substantially coincide.

  Then, the door closing apparatus 14 used as the premise of this invention is demonstrated.

  A pair of hanging brackets 31 and 32 are fixed with bolts in front of and behind the upper edge of the sliding door 1, and a door wheel 33 is attached to the hanging bracket 31 on the door end side via an axle (not shown). Further, a rotary hydraulic control device 34 (rotary door check) is attached. Moreover, although not specifically illustrated, the door cart is attached to the hanging metal fitting 32 on the door bottom side via an axle.

  The door roller 33 rolls on the rail surface of the guide rail 15 and is guided by the guide pin 21 at that time. The wife sliding door 1 moves in the front-rear direction, thereby opening and closing the wife doorway 12. At this time, the gear 34a of the rotary hydraulic control device 34 meshes with the lower rack gear 15a of the guide rail 15 of the door closing device 14 and further meshes with the upper rack gear 35a of the brake rail 35, thereby rotating the door sliding door 1. The door check action is produced in both the direction and the opening direction.

  The guide rail 15 that supports the door pulley 33 of the sliding door 1 has an L-shaped cross section, and a rack gear 15a is fixed to the horizontal portion by screws. Stoppers 36 are screwed to the left and right ends of the guide rail 15, and when the sliding door 1 is fully opened or fully closed, a stopper roller 37 provided on the sliding door 1 comes into contact with and engages with the stopper 36. The wife sliding door 1 is held in the fully open position and the fully closed position. Since this stopper mechanism is conventionally well-known, the description about the specific mechanism is abbreviate | omitted. The stopper roller 37 is screwed to the suspenders 31 and 32.

  The brake rail 35 is also an L-shaped member, and a rack gear 35a is fixed to the horizontal portion by screws.

  The guide rail 15 provided with stoppers 36 at both left and right ends and the brake rail 35 are attached to a rail support base 38 to form the door closing device 14.

  The door check mechanism using the rotary hydraulic control device 34 and the rack gears 15a and 35a of the rails 15 and 35 is a well-known door check mechanism (see, for example, Japanese Patent No. 3069095), and a detailed description of the mechanism is omitted. However, the rotary hydraulic control device 34 is free for rotation in one direction of the gear 34a and hydraulically brakes the rotation in the other direction. Therefore, at the initial stage of the opening operation from the fully closed state, the gear 34a meshes with the rack gear 15a of the guide rail 15 and freely rotates in one direction, and at the end of the opening operation, meshes with the rack gear 35a of the brake rail 35. Rotate in the direction. Since the rotary hydraulic control device 34 exerts a braking action against the rotation in the other direction, the sliding door 1 is braked at the end of the opening operation. In the initial stage of the closing operation from the fully opened state, the gear 34a meshes with the rack gear 35a of the brake rail 35 and freely rotates in one direction. At the end of the closing operation, the gear 34a meshes with the rack gear 15a of the guide rail 15 and applies braking force. Rotate in the other direction while receiving. Accordingly, the sliding door 1 is braked at the end of the opening operation and the closing operation. When the door sliding door 1 reaches the end point of the opening operation and the end point of the closing operation, the stopper rollers 37 provided on the front and rear hanging hooks 31 and 32 come into contact with the stoppers 36 provided on the left and right ends of the guide rail 15. 1 is held with a predetermined holding force in either the closed position or the open position.

  Since it comprised as mentioned above, since the closing plates 4 and 5 are supported so that it can move to the up-down direction in the indoor side and the vehicle outer side of the lower end part, when opening the sliding door 1, At the beginning of opening, the engaging pin member 6 moves in the long holes 4a and 5a from the lower end side toward the upper end side. Thereby, the sliding door 1 moves so that the gap between the lower edge and the floor surface gradually increases (see the operation line S2 in FIG. 2), whereas the lower edges of the closing plates 4 and 5 slide on the floor surface. It moves while moving (see operation line S1 in FIG. 2). That is, the closing plates 4 and 5 move horizontally so as to always close the gap between the lower edge of the sliding door 1 and the floor surface.

  Since the engaging pin member 6 reaches the upper end of the long holes 4a and 5a before the mounting plate 22 of the guide pin 21 (see the point P of the operation line S1), thereafter, the engaging pin member 6 is interposed via the engaging pin member 6. The door is lifted by the door 1 (see operation line S1). And since the lower end edge of the closing plates 4 and 5 is lifted to the upper side of the mounting plate 22 of the guide pin 21, when the sliding door 1 is fully opened, as shown in FIG. 7 and FIG. 22 will not come into contact. When the sliding door is fully opened, the guide pin 21 is slidably engaged with the recessed portion (member 26) of the lower end edge of the sliding door body 1A to prevent the sliding door 1 from swinging.

  And if the force which opens the sliding door 1 by a passenger etc. does not act, since the guide rail 15 will incline, the sliding door 1 will move to the direction which closes the entrance / exit 12 by the effect | action of gravity. When the wife sliding door 1 closes the wife doorway 12, the recessed portion (member 26) engages with the lower rail 23, and the swing of the wife sliding door 1 due to wind or the like is prevented.

  Thus, since the clearance between the door end side portion of the lower end edge of the wife sliding door 1 and the floor surface is closed by the closing plates 4 and 5, when the door sliding door 1 is opened and closed, the door sliding door 1 and the floor surface are separated. It is possible to prevent the feet of passengers wearing sandals from being caught in the gap.

  In particular, since the closing plates 4 and 5 are supported so as to be movable in the vertical direction, the opening and closing operation of the sliding door 1 is not impaired. That is, when the lower end edges of the closing plates 4 and 5 come into contact with the floor surface, the closing plates 4 and 5 are displaced upward, so that the opening / closing operation of the sliding door 1 is performed smoothly.

  Moreover, since the closing plates 4 and 5 can be attached without removing the guide pin 21 and the lower rail 23, etc., as a countermeasure against the steadying of the sliding door 1, it can be easily attached to the existing sliding door 1 of the vehicle. Can do.

  In the above embodiment, a long hole extending in the vertical direction is formed in the closing plate, and the engagement pin member that is slidably engaged with the long hole is provided in the sliding door. In addition, an elongated pin extending into the elongated hole may be formed, and an engagement pin member slidably engaged with the elongated hole may be provided on the closing plate.

  Further, not only the engagement relationship between the long hole and the engagement pin member, but also, for example, a recess or groove (as the engaged portion) and a slidable engagement with the recess or groove (as the engagement member) It is also possible to use the engagement relationship with the convex member.

  Furthermore, in the above-described embodiment, the mounting plate 22 of the guide pin 21 is lifted by lifting the closing plates 4 and 5 in the engaging relationship between the long holes 4a and 5a and the engaging pin member 6 when the sliding door 1 is fully opened. However, instead of this, it is also possible to adopt a configuration in which the closing plate is placed smoothly by using the door side portion of the mounting plate as an inclined surface. .
