[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an outer holo device provided between wives of a railway vehicle.
[0002]
[Prior art]
Many wives (connections) of railway vehicles have spaces where people can enter, and there is a risk of falling while the platform is stopped. Therefore, an outer holo device (falling prevention device) described in Patent Document 1 below has been proposed. As shown in FIGS. 10 (A) and 10 (B), this conventional outer holo device is provided with plate members 102 and 102 butting each other at the lower part of the end portion of each adjacent vehicle 101 and 101.
[0003]
That is, the rubber fall-preventing plate 102 is attached to the fitting part 103 of the wife part to prevent the passenger from falling on the track. Further, by making the fall prevention plate 102 provided on both wives rubber, the gap between the vehicle wife is reduced due to a curve or the like while the vehicle is running, and even if the fall prevention plates 102 interfere with each other, they are later returned to the basic shape. Ingenuity has been made.

[0005]
[Problems to be solved by the invention]
However, in the conventional outer holo device, since the rubber fall prevention plates 102 attached to both the wife interfere with each other with the movement of the vehicle (see FIG. 10C), an elastic material such as rubber is used. It was necessary and could not be said to be excellent in design. Further, since the conventional outer holo device is intended only to prevent falling, there is no sense of unity with the vehicle in design. In order to improve the design, the fall prevention plate is also painted with a sense of unity with the vehicle, but even in that case, it interferes with each other with the movement of the vehicle, so the surface coating is Bald and repainted.
[0006]
Further, in the conventional outer holo device, the fall prevention plate is easily cracked or broken by the interference. Also, if left in an interfering state at a high temperature in a garage or the like, there is a risk that it will be difficult to return to the basic shape or the worst will not return.
[0007]
Furthermore, the fall prevention plate may be bent to the outside of the vehicle due to wind pressure during high-speed traveling. In addition, since the vehicle and the fall prevention plate are not arranged flush with each other, the unevenness and the friction coefficient of the surface are large, vortices are easily generated, and this is a cause of generation of outside noise. In addition, even when the fall prevention plate is bent, the flow along the vehicle surface is separated, which causes noise. That is, the air flow along the vehicle surface peels off at the fall prevention plate and reattaches to the wife surface, side surface, and roof surface of the following vehicle, causing noise.
[0008]
Further, in the conventional outer holo device, the fall prevention plate is only projected from both the wives. Therefore, when the vehicle stops at the curved home (outside the curved surface), the wife is widened. For this reason, a gap that allows a person to enter between the wife and the fall prevention plate is generated.
[0009]
The present invention has been made in view of the above circumstances, and its main purpose is to provide an outer holo device that improves the design, has a sense of unity with the vehicle, and prevents baldness and repainting of the surface coating. It is in. Another object of the present invention is to prevent cracks, cracks, and deformation of the fall prevention plate and to prevent noise by arranging the vehicle and the fall prevention plate on a smooth surface. Furthermore, it is intended to effectively prevent falling even in a curved home.
[0010]

[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the outer holo device for a railway vehicle according to the present invention will be described in more detail.
FIG. 1 is a view showing a railway vehicle to which an embodiment of an outer holo device of the present invention is applied, and FIG. 2 is a longitudinal sectional view thereof.
[0016]
As shown in this figure, the outer holo device 1 of the present invention is provided between the wives 2a, 2a of two adjacent vehicles 2, 2, and is provided symmetrically on both sides of the vehicle width method across the connecting portion. . The outer holo device 1 of this embodiment includes a fall prevention plate 3 disposed between the wives 2a and 2a as a main part. As will be described later, the fall prevention plate 3 can be formed by a hard single plate such as a metal plate, for example, because it is attached without the possibility of interference.
[0017]
The fall prevention plate 3 of the present embodiment preferably has a cross-sectional shape along the contour of the vehicle 2 as shown in FIG. That is, it is good to make it the shape along the curve of the side surface of the vehicle 2. Further, the size of the fall prevention plate 3 is not particularly limited, but in the illustrated example, the width dimension is about the distance between the wives when running in a straight line (FIG. 3), and the height dimension is from the lower side of the vehicle side wall to the lower part of the roof It is set to a degree. As shown in FIG. 2, such a fall prevention plate 3 is held at each of the wives of the adjacent vehicle 2 at two locations, upper and lower.
[0018]
3 and 4 are views showing a holding structure of the fall prevention plate 3 of the present embodiment, FIG. 3 is a plan view, and FIG. 4 is a front view in which the fall prevention plate 3 is omitted.
As shown in this figure, in this embodiment, a pantograph-like holding mechanism is provided between the wives of adjacent vehicles. The pantograph-like portion 4 is a link mechanism that combines bar materials (plate materials), and is a parallelogram that can be expanded and contracted. In the illustrated example, the pantograph-like portion 4 is configured by a combination of two parallelograms.
[0019]
That is, two long bars 5 and 5 are connected to each other at the center portion so as to be swingable in a cross shape (X shape) with pins, and short bars 6 each having a half length are connected to each end of the long bar 5. Are connected so as to be swingable with pins, and the tip portions of the upper and lower short bars 6 and 6 are connected to be swingable with pins. As a result, as shown in FIG. 4, two parallelograms are arranged on the left and right sides, and are extendable in the left-right direction (that is, the longitudinal direction of the vehicle) in FIG. Moreover, since the pantograph-like portion 4 combines parallelograms symmetrically left and right and up and down in FIG. 4, the central connection portion is always arranged at the central portion between the wives, regardless of the stretched state. It will be.
[0020]
The left and right ends (both ends in the expansion / contraction direction) of the pantograph-like portion 4 are connected to the wives of each vehicle through the universal joint 7. In this embodiment, the end portion is held by a spherical bearing. Specifically, as shown in FIG. 3, a through hole is formed in the bearing portion that protrudes from the end portion along the vehicle width direction, and the inner peripheral surface of the through hole has a substantially spherical belt shape. Formed on the surface. A substantially spherical ball is rotatably held in the through hole. The short bar is swingably connected to a shaft portion penetrating and held by the ball.
[0021]
A shaft 8 is passed through the center portion of the pantograph-like portion 4 (the connecting portion between the long bars 5) along the vehicle width direction via a slide bearing. A fall prevention plate 3 is fixed to the shaft 8 via a bracket 9 at the outer end in the vehicle width direction. In addition, a flange-like spring seat 10 is fixed to the shaft 8 at the inner end in the vehicle width direction. The shaft 8 is fitted with a compressed coil spring 11 between the spring seat 10 and the central connection portion of the pantograph-like portion 4.
[0022]
Here, the pantograph-like portion 4 is held by the wife portion and is substantially fixed in the vehicle width direction, and the fall prevention plate 3 and the shaft 8 are fixed. Accordingly, the spring seat 10 of the shaft 8 is always urged inward in the vehicle width direction by the force with which the coil spring 11 is extended. Therefore, the fall prevention plate 3 is always urged inward in the vehicle width direction, and can move outward in the vehicle width direction against the urging force of the coil spring 11 (that is, while compressing the coil spring 11). It is said that.
[0023]
By the way, the pantograph-like portion 4 is provided with a stopper 12 that prevents the falling prevention plate 3 from being pulled inwardly in the vehicle width direction. In the present embodiment, a stopper member 12 is formed by protruding a rod member from the swing holding portion to the vehicle width direction outer side at the connecting portion between the long rod 5 and the short rod 6. The ball 12a is rotatably held at the tip of the stopper 12 of this embodiment. Specifically, “free bear” (registered trademark) can be used at the tip of the stopper 12 of this embodiment. With such a configuration, when the fall prevention plate 3 moves inward in the vehicle width direction, the stopper 12 comes into contact with the back surface of the fall prevention plate 3 and further pull-in of the fall prevention plate 3 is prevented. As shown in FIG. 3, when the fall prevention plate 3 is in contact with the stopper 12, the fall prevention plate 3 is in a state along the vehicle side wall.
[0024]
As shown in FIG. 3, inclined plates 13 that are inclined inward in the vehicle width direction as they go inward in the left-right direction are provided on the left and right sides of the back surface of the fall prevention plate 3. On the other hand, a roller 14 is held at the end of the wife portion on the outer side in the vehicle width direction. As shown in FIG. 3, the roller 14 is rotatable around a rotation axis along the vertical direction. The roller 14 is brought into contact with an end portion on the outer side in the left-right direction of the inclined plate 13 in a straight running state in which the fall prevention plate 3 is in contact with the stopper 12. The inclined plate 13 is provided corresponding to the mounting height of the roller 14.
[0025]
The railway vehicle to which the outer holo device 1 of the present embodiment is applied is in the state shown in FIG. On the other hand, FIG. 5 is a plan view showing a state of the railway vehicle to which the outer holo device 1 of the present embodiment is applied during curve traveling, and FIG. 6 shows the outer holo device 1 on both sides in the vehicle width direction (FIG. 5). It is an enlarged view of A part and B part.
[0026]
First, as shown in FIG. 6 (B), a case will be described in which adjacent wives are close to each other during curve traveling and the distance between the wives is reduced. In this case, along with the reduction of the pantograph-like portion 4, the roller 14 advances inward in the width direction of the fall prevention plate 3 along the inclined plate 13 disposed on the back surface of the fall prevention plate 3. As a result, the fall prevention plate 3 is pushed outward in the vehicle width direction against the urging force of the coil spring 11. Then, when the curve traveling is finished, the roller 14 advances along the inclined plate to the outside in the width direction of the fall prevention plate 3, and the fall prevention plate 3 returns to the inside in the vehicle width direction by the urging force of the coil spring 11. Become. In addition, the fall prevention plate 3 does not move inward in the vehicle width direction by a certain amount or more due to the contact of the stopper 12 with the fall prevention plate 3.
[0027]
On the other hand, as shown in FIG. 6 (A), a case will be described in which adjacent wives are separated from each other at the time of curve traveling and the distance between the wives is increased. In this case, the pantograph-like portion 4 is stretched as the wife distance increases. Thereby, although the contact state of the inclined plate 13 and the roller 14 is cancelled | released, the fall prevention plate 3 does not move to the vehicle width direction inner side more than necessary by the effect | action of the stopper 12. FIG. As a result, the fall prevention plate 3 is disposed at the central portion of the gap between the wives and substantially disposed along the side surface of the adjacent vehicle.
[0028]
Thus, according to the outer holo device of the above embodiment, the center of the wife is determined by the pantograph-like portion 4 even if the distance between the wife changes due to the deviation of the vehicle. Therefore, the fall prevention plate 3 disposed at the center of the pantograph-like portion 4 is always present at the center of the wife. When the distance between the wife is reduced, the roller 14 slides along the inclined plate 13 of the fall prevention plate 3 so that the fall prevention plate 3 is pushed outward. Therefore, the fall prevention plate 3 does not hit the vehicle body.
[0029]
For this reason, the fall prevention plate 3 can be constituted by a single panel and does not require its own deformation. In addition, the smoothness that is continuous with the vehicle contour can provide continuity of the vehicle and improve the design. In this case, it goes without saying that the paint can be continuous with the vehicle. Moreover, the fall prevention plate 3 can be prevented from interfering with each other by making the fall prevention plate 3 into a single panel.
[0030]
The link mechanism (pantograph-like portion) 4 and the fall prevention plate 3 are made of a rigid body such as metal, so that there is no possibility of bending due to wind pressure. Further, the fall prevention plate 3 is arranged along the vehicle contour during traveling and stopping at the straight portion. Moreover, even if wind pressure is applied by the action of the coil spring 11, the fall prevention plate 3 is reliably arranged along the vehicle body contour. Note that the fall prevention plate 3 is configured so as to follow the side surface of the vehicle as much as possible even during a curve run.
[0031]
Further, the pantograph-like portion 4 was held on the wife portion by being freely fixed via a spherical bearing 7 to give freedom of movement. Thereby, it is possible to prevent the outer holo device 1 from being overloaded even by rolling of the vehicle body, vertical and horizontal vibrations. That is, it is possible to cope with various behaviors such as a change in the distance between the wife when the vehicle is traveling, a twisting of the vehicle, and a lateral displacement.
[0032]
By the way, as described above, the distance between the wife may be smaller or larger than the width dimension of the fall prevention plate 3 due to the bias. The fall prevention plate 3 cannot be changed in width because it is a single plate, but when the distance between the wife is small, it is pushed out to deal with it, and when the distance between the wife is large, it is arranged at the center of the wife. And dealt with. In addition, since the extrusion of the fall prevention plate 3 is within the vehicle limit range, there is no inconvenience in traveling. Further, the shaft 8 that holds the fall prevention plate 3 is always urged toward the pull-in side and tries to pull the fall prevention plate 3 back to a predetermined position, so that the fall prevention plate 3 is only minimally expanded.
[0033]
Furthermore, as described above, the fall prevention plate 3 does not interfere with other members, so that the fall prevention plate 3 is not peeled off or worn away by wear, and there is no need for replacement. . Furthermore, by arranging the fall prevention plate 3 smoothly with the vehicle contour, the friction coefficient can be reduced by smoothing one piece with a solid object, and the flow of air along the surface of the traveling vehicle body is not disturbed, and the connection In addition to improving noise reduction in the vehicle, it is possible to reduce the influence of the snake behavior of the vehicle and improve the riding comfort.
[0034]
In addition, because of the action of the pantograph-like portion 4, the fall prevention plate 3 is always arranged at the center of the wife, so even in a curved platform where the distance between both cars is wide, there is no space for people to enter between the wife and the fall prevention plate 3. Smaller and more secure for passengers. In addition, even if the passenger is about to fall from the home and hits the fall prevention plate 3, the force can be supported by the roller 14 or the stopper 12 that receives the fall prevention plate 3, so that safety for the passenger is further ensured.
[0035]
FIG. 7 is a view showing a second embodiment of the outer holo device of the present invention, and shows only one outer holo device 21 in the vehicle width direction. FIGS. 8 and 9 are views showing a state of the railway vehicle at the time of curve traveling to which the outer holo device 21 of this embodiment is applied.
[0036]
Also in this embodiment, a single plate fall prevention plate 22 is disposed between the wives as in the first embodiment. Leaf springs 23 are provided at the left and right ends of the fall prevention plate 22, respectively. Each leaf spring 23 is substantially L-shaped, one piece 23a is overlapped and fixed on the back surface of the fall prevention plate 22, and the other piece 23b is arranged toward the inner side in the vehicle width direction. In addition, you may fix a fall prevention board to the center piece using a substantially U-shaped leaf | plate spring.
[0037]
In FIG. 7, a slide roller 24 is rotatably held at the tip of the leaf spring 23 arranged on the left side. The slide roller 24 is held so as to be rotatable about an axis along the vertical direction, and is held on the outer surface of the leaf spring 23. An end of a wire 26 is fixed to the bracket 25 for holding the slide roller 24, and the wire 26 is constantly urged toward the winding side by a winding drum 27. The winding drum 27 is fixed to the center side of the end wall in the vehicle width direction, can wind the wire 26, and always applies a biasing force in the winding direction.
[0038]
Thereby, the slide roller 24 is always urged inward in the vehicle width direction. Moreover, the slide roller 24 is normally urged toward the wife side by the urging force of the leaf spring 23, so that it can be moved in the vehicle width direction substantially along the wife wall. The slide roller 24 is held only by the wire 26 and the leaf spring 23, and is held with a relatively high degree of freedom. Further, a stopper 28 is provided on the end wall so as to protrude slightly outside the winding drum 27 in the vehicle width direction. When the slide roller 24 comes into contact with the stopper 28, the wire 26 is wound more than a predetermined amount. Is blocked. When the slide roller 24 is in contact with the stopper 28, the fall prevention plate 22 is disposed substantially along the vehicle side wall.
[0039]
On the other hand, a slide member 29 is provided at the tip of the leaf spring 23 arranged on the right side in FIG. The slide member 29 is held along the slide arm 30 so as to be able to advance and retreat. The slide arm 30 is held by a plate 31a of a hinge 31 fixed to the end portion. The hinge 31 is configured so that two plates 31a and 31b are rotatable around a rotation axis. The rotation axis is disposed at an end portion on the outer side in the vehicle width direction, and one plate 31b is used as a vehicle wife portion. It is fixed. The other plate 31 a is provided with a slide arm 30 along its longitudinal direction, and the slide member 29 is held so as to be slidable along the slide arm 30.
[0040]
An end portion of a wire 26 is fixed to the slide member 29, and the wire 26 is constantly urged toward the winding side by a winding drum 27. The winding drum 27 is fixed to the center side of the end wall in the vehicle width direction, can wind the wire 26, and always applies a biasing force in the winding direction. Thereby, the slide member 29 is also always urged | biased inside a vehicle width direction like the slide roller 24. FIG. A stopper (not shown) is provided at the tip of the slide arm 30 to prevent further movement inward in the vehicle width direction. The slide arm 30 is biased in the direction along the end wall by the biasing force of the leaf spring 23.
[0041]
By the way, the roller 32 is each provided in the edge part (wife pillar) of the vehicle width direction outer side of both wife parts. Similarly to the first embodiment, the roller 32 is also rotatable about an axis along the vertical direction.
[0042]
Since it is such a structure, it will be in a state as shown in FIG. 7 at the time of a straight line driving | running | working, and will be in a state as shown in FIG. 8 at the time of curve driving | running | working. That is, as shown in FIG. 8B, when the distance between the wife is reduced, the roller 32 presses the two pieces (23b, 23b) of the leaf spring 23 close to each other, and the slide roller is accompanied accordingly. 24 and the slide member 29 are pulled out against the urging force of the winding drum wire 26 and moved outward in the vehicle width direction. Thereby, the fall prevention plate 22 is pushed out to the width direction outer side of the vehicle.
[0043]
On the other hand, as shown in FIG. 8A, when the distance between the wives is increased, the proximity state between the roller 32 and the leaf spring 23 is released, and the slide roller 24 and the slide member 29 respectively contact the stopper. It will be held in contact. In any case, the fall prevention plate 22 is arranged at the center of the wife as in the case of the first embodiment.
[0044]
As shown in FIG. 9, when two adjacent vehicles pass through the S curve, the slide arm 30 is rotated by the hinge 31 and the load applied to the leaf spring 23 is reduced.
[0045]
Thus, in the outer holo device of the present embodiment, the fall prevention plate 22 can be moved to an appropriate position by the force of the leaf spring 23. Moreover, the fall prevention board 22 is comprised with the panel of a single board, can give the continuity between vehicles, and can improve the design property. Furthermore, the fall prevention plate 22 is fixed to the vehicle with a hinge 31 on the end face of one vehicle, and the other vehicle is supported by a free support so as to follow the rolling, vertical and horizontal vibrations of the vehicle body. The wife surface was freely moved by the slide roller 24. As shown in FIGS. 8B and 9, the slide roller 24 can be held even when it floats from the body surface.
[0046]
By the way, although the distance between the wives may be smaller or larger than the width dimension of the fall prevention plate 22 due to the bias, the fall prevention plate 22 is a single plate, so the width dimension cannot be changed. Therefore, in this embodiment, when the distance between the wife is small, it is configured to push it out within the vehicle limit range. That is, the fall prevention plate 22 is pushed out by sandwiching the spring plate 23b by the roller 32 attached to the end post. Conversely, when the distance between the wives increases, the slide roller 24 on the free support side (left side in FIG. 7) is fixed by the stopper 28, and the slide member 29 on the other support side (right side in FIG. 7) is also held by the stopper. Thus, the fall prevention plate 22 can be moved to an appropriate position by the spring force of the plate spring 23.
[0047]
Even if the inclination of the fall prevention plate 22 is changed due to the deviation of the vehicle, it is necessary to always return to the initial position during straight running. As a mechanism for this, a structure is adopted in which the end of the leaf spring 23 is pulled by the winding drum type wire 26 and returned to the initial position. Further, during running / stopping at the straight portion, even if wind pressure is applied to the plate, the fall prevention plate 22 is always smoothed to the vehicle body contour by the roller 32 of the end post.
[0048]
As described above, according to the embodiments of the present invention, the fall prevention plates 3 and 22 formed into a single panel are always moved to the center between the vehicle wives to close the gap between the vehicle wives, so that the passenger can You can prevent accidents such as falling. Further, since the interference with the vehicle body or the like is eliminated, the coating, chipping, cracking, deformation, etc. of the fall prevention plates 3 and 22 and the vehicle body are improved. Furthermore, it is possible to reduce noise generated between the connections. That is, by smoothing the outer horo (falling prevention plates) 3 and 22 with the vehicle contour, it is possible to reduce the noise generated between the connections. In addition, by smoothing the outer holo 3 and 22, it is possible to eliminate the gap between the vehicles, give a sense of unity with the vehicle body outer plate, and improve the finding.
[0049]
