The end opposite to the vehicle 20 has a circle slightly larger in diameter than the width of the elongated hole 41. Are formed continuously. On the substrate 28A side, a bolt 43 is fixed at the center of the locking hole 42 so as to protrude downward. A locking plate 44 is fitted to the bolt 43, and the locking plate 44 is
And is fitted in the locking hole 42. The outer peripheral surface of the locking plate 44 is formed at the entrance end 4 of the elongated hole 41.
1a. The locking plate 44 is
It is formed of a material that can be broken or deformed when subjected to a strong impact exceeding a predetermined level, such as a synthetic resin plate or an aluminum plate. The locking plate 44 is supported by the receiving plate 45 by inserting a receiving plate 45 through the bolt 43 and screwing a nut 46.

With such a structure, the two plates 28
A and 29 are held in the state shown in FIGS.
When a strong impact force greater than a predetermined force is applied to A and 29 in the direction A shown in FIG. 6, the impact force breaks or deforms the locking plate 44, and the two plates 28A and 29 are relatively moved in the direction A. It can be moved.

Next, the base end 30a (see FIG. 3) of the second extension plate 30 is disposed along the distal end surface 29b of the first extension plate 29, and the second extension plate 30 It is provided rotatably in the up-down direction by a hinge fitting 47 provided at the tip in a horizontal direction orthogonal to the passage direction. As shown in FIG. 1, the planar shape of the distal end of the second extension plate 30 is cut from the central portion 30b of the distal end to the rear side in a C-shape.

3a. That is, the substrate 28
When A rotates upward around the hinge 37 and inclines to a predetermined position (posture), the stopper portion 52a contacts the lower surface 53a of the side panels 53, 53 so as not to rotate further upward. It regulates.

The two release-side metal frames 24, 25 are pressed by pressing devices (not shown) similar to the pressing devices 15, 16 shown in FIG. Next, the operation of the present embodiment will be described.

During normal operation, when the facing distance between the vehicles or between the vehicle and the release-side metal frame is within a normal range and there is no pitching amount, as shown in FIGS. 1st and 2nd extension board 2 in 27
9 and 30 are extended from the substrate 28A, and each of the plates 28A, 29 and 30 is in a horizontal state and one of the crossover plates 2
6. Therefore, the center 30b of the distal end of the second extension plate 30 is close to the upper surface of one of the crossover plates 26. Further, the tips of the sub-plates 31, 31 are also close to one of the crossover plates 26.

When a large amount of pitching occurs between the vehicles or between the vehicle and the release-side metal frame, for example, as shown in FIG. When the 32 portion has moved upward, the leading portion of one crossing plate 26 is used to move the other crossing plate 27.
Is pushed up, and the substrate 28A and the first extension plate 29 move upward about the hinge fitting 37. At this time, the second extension plate 30 is inclined by its own weight so that the tip portion moves downward around the hinge fitting 47, and the state in which the sand plate 48 is in contact with one of the crossover plates 26 is maintained. Therefore, the front end central portion 30b maintains a closed state close to the upper surface or the floor surface of one of the crossover plates 26. Further, the sub-plates 31, 31 are also inclined downward, and the ends thereof are in contact with one of the crossover plates 26 and are closed.

Therefore, there is no large gap between the upper surface or floor surface of one of the crossover plates 26 and the tip of the other crossover plate 27, so that passengers or the like may trip on the crossover plate or legs may be caught between the crossover plates. Is prevented.

In addition to such pitching, the vehicle 2
In the case where the distance between 0 and the release side metal frame 24 is reduced within the normal range, one of the crossover plates 26 is inclined so that the front thereof is slightly lowered, so that the first extension plate 29 of the other crossover plate 27 is reduced. The amount of lifting (raising amount) can be reduced as compared with the case where one of the crossover plates 26 is in a horizontal state. This can reduce the possibility that the passenger will trip over the raised crossing board or hinder walking.

Next, a case where the distance between the vehicles or between the vehicle 20 and the release-side metal frame 24 is abnormally reduced in the event of a vehicle collision will be described. For example, in the case where the above-mentioned pitching does not occur, that is, when the collision occurs in the state of the horizontal position of the transition plate as shown in FIG.
The first extension plate 29 is suddenly and strongly pressed in the direction of the release side metal frame 24 by hitting the engagement member 39 of the extension plate 29.

Due to this impact force, the locking plate 44 provided on the substrate 28A shown in FIGS.
At this time, the two substrates 28A and the first extension plate 29 are relatively movable in the direction of arrow A in FIG. Then, the pressing member 36 further presses the locking member 39, and as shown in FIG. 11, the first extension plate 29 moves toward the release side metal frame 24,
The first extension plate 2 is pushed and moved by being guided by the guide 38.
9, the second extension plate 30 connected to the leading end of the release side metal frame 24.
In the direction of the connecting passage of the other crossing plate 27 is reduced.

Therefore, as shown in FIG.
Even if the distance between the zero and the release side metal frame 24 is abnormally reduced, it is possible to prevent the distal end portion 30b of the other crossover plate 27 from largely entering the passenger compartment R of the vehicle 20.

Next, a description will be given of a case where a pitching occurs between the vehicles or between the vehicle 20 and the release side metal frame 24 at the same time as the abnormal contraction as shown in FIG.

First, for abnormal reduction, the first extension plate 29 of the other cross plate 27 is moved in the same manner as described above. At this time, even if a pitching state occurs after the pushing member 36 engages with the engaging member 39, the projection 36a of the pushing member 36 and the projection 39a of the engaging member 39 are engaged, and the two members 36, 3
9 is maintained, and the first extension plate 29 is reliably pushed and moved.

In addition, since the pitching amount is large,
When the pressing member 36 abuts on the lower surface of the first extension plate 29 and the force of the pressing member 36 for pushing the first extension plate 29 upward becomes abnormally high, first, the substrate 28A of the other crossing plate 27 is contacted. The stopper 52 provided is a side panel 53,
The lower plate 53 abuts against the lower surface 53a to prevent further upward movement of the two plates 28A, 29, and the seat plate 35 of the stopper piece 33 of one of the crossover plates 26 and the mating surface of the vehicle body 20 are shown in FIG.
2 or all or any of the stopper piece 33, the seat plate 35, and the end face are deformed, and the posture of one of the crossover plates 26 shown in FIGS. And retreats downward as shown in FIG.

Therefore, the tip of the other crossing plate 27 is prevented from being abnormally higher than the cabin R of the vehicle 20 or the plane F of the aisle, thereby preventing a secondary danger to passengers. Also,
The second extension plate 30 of the other crossover plate 27 is
, The tip of the second extension plate 30 is constantly urged downward by its own weight, and the tip 3
It is prevented that the gap between Ob and the cabin R or the plane F of the passage becomes large.

The pressing member 36 of the one crossing plate 26 is used.
The notch 26b is formed at the center of the crossover plate 26 and is provided at the back of the notch 26b, as shown in FIG. In the event of a collision such as
Numeral 6 is such that the engagement relationship with the engagement member 39 as shown in FIG. 12 is maintained.

Further, as described above, the engaging member 39 is connected to the first
These members 39 and 3 are provided on the lower surface of the extension plate 29 and the pressing member 36 is provided at the tip of one of the crossover plates 26.
6 is covered by a crossing board, so there is no obstacle to traffic.

The connecting means 40 is connected to both plates 28 and 29.
May be connected by a bolt or a pin, and when a predetermined or more shearing force acts on the bolt or the pin, the bolt or the pin may be configured to be shear-ruptured.

In another embodiment corresponding to the first aspect of the present invention, in addition to the above-described embodiment, the first extension plate 29 and the second extension plate 30 of the above-described embodiment are separated from each other. Alternatively, the extension plate 28B may be formed of a single plate without using a single plate. In an embodiment corresponding to the second aspect of the present invention, the first extension plate 29 or the second extension plate 30 is further divided into a plurality of pieces in the connecting passage direction, and the divided portion can be rotated in the vertical direction. And the extension plate 28B may be composed of three or more sheets.

[0047]

As described above, according to the first aspect of the present invention, in the event of a collision of a vehicle, the secondary end is such that the end of the crossover plate largely enters the passenger compartment of the vehicle and hits the passenger's foot. Can be prevented from causing a natural disaster. Further, according to the invention described in claim 2, in addition to exhibiting the effect of preventing entry into the room, even when the pitching amount of the vehicle becomes large due to the collision of the vehicle, the one crossing plate and the other crossing plate can be used. The gap with the tip can be kept extremely small, and the tip of the transition board can be prevented from hitting the tip of the transition board by opening the tip of the transition board greatly, causing passengers to suffer a great disaster. Secondary disasters caught between the crossover boards can be further prevented.
