Description

[Detailed explanation of the idea] This invention relates to a vehicle plate.

Traditionally, vehicle plates have been made by partially overlapping a metal plate pivotally attached to the floor of one vehicle body with a metal plate pivotally attached to the floor of the other vehicle body, or by holding the metal plate between the vehicle bodies with a link device. Two metal plates, one end of which is pivotally attached to the floor of each vehicle body, are placed on top of a fixed support plate.

However, in any of these cases, giving the plate a bending strength in the longitudinal direction of the car body also increases its torsional rigidity, so if there is a relative inclination between the floor surfaces of both car bodies when the car body rolls, they will overlap. There is a risk of tripping or getting one's foot caught between the metal plates that are raised, creating the disadvantage that safety at the plate parts cannot be fully guaranteed.

The object of this invention is to provide a vehicle plate that can eliminate the above-mentioned disadvantages.

To explain the configuration of this invention based on an example, the plate 1 is a corner member 2 having strong resistance to bending.
A required number of connecting holes 2b are provided on each side of the arranged corner members 2 in a direction perpendicular to the arrangement direction. The corner members 2 are loosely connected by a connecting member 3 smaller than the hole 2b, and both ends of the connected corner members 2 are attached to the floor surfaces of adjacent vehicle bodies 4 and 5.

As the corner member 2, a corner member 2 having strong resistance to bending can be used regardless of its shape, but a corner member 2 in which a square pipe 2a is used will be described below. The square pipes 2a arranged in parallel are connected to slightly larger C-shaped clamping frames 9, 9, which are disposed on both sides of the square pipes with buffer rubber 8 interposed therebetween. The adjacent square pipes 2a are held by connecting members 3, 3 passing through the holes 2b of
The comrades are loosely connected so that they have some degree of freedom of movement. The end of the plate 1 on the vehicle body 4 side is hinged to a hinge 13 by an L-shaped member 12 via a cushioning rubber 11.
It is fixed to the floor surface 6 of the vehicle body 4 by this hinge 13, and the arcuate end surface on the vehicle body 5 side is attached to the floor surface 6 of the vehicle body 5 side by an arcuate frame 15 attached via a cushioning rubber 14. It is slidably mounted on a sliding plate 16 fixed to the surface 7. A gap 17 between the floor end surface 7a of the plate receiving portion of the vehicle body 5 and the arcuate frame 15 opposed thereto is closed by a batten 18 fixed to the upper surface of the arcuate frame 15.

When the blocking plate 1 is configured in this way, even if the square pipe 2a is given strength against the bending moment in the length direction, the torsional rigidity as a whole is reduced because it is loosely connected in the form of a blind by the connecting member 3. can be kept small, so that when the vehicle bodies 4 and 5 roll, the arcuate frame 15 of the plate 1 placed on the floor 7 of the vehicle body 5 due to its own weight will move against the vehicle body 4.
The vehicle body 5 is easily deformed following the floor surface 7 of the vehicle body 5 which is inclined relative to the floor surface 6 of the vehicle, and does not rise from the floor surface 7.

Therefore, not only can it prevent troubles such as tripping or getting your foot caught at the boundary between the floor surfaces 6 and 7 when passing the board 1, but also the board can be used by utilizing its rigidity against bending. Since the deflection of the board 1 can be reduced, passengers can safely move back and forth on the board 1.

Furthermore, one end of the plate 1 is pivotally connected to the floor surface 6 of one car body 4 by a hinge 13, and the other end is placed on the sliding plate 16 of the other car body 5 due to its own weight. Only one side needs to be lifted, making handling and operation easier.

FIG. 4 shows another embodiment of this invention, in which both ends of the plate 1A are connected to the arc frame 1 on the vehicle body 5 side of the embodiment described above.
The structure is the same as that shown in Fig. 5, and the case is shown in which it is placed on the sliding plate 16 as in the case of Fig. 2.

When the plate 1A is configured symmetrically in this way, in addition to the effects of the above embodiment, the vehicle body 4 on both sides,
The underframe structure and floor structure of No. 5 can be made common.

As explained above, in this invention, the plate is formed by arranging a large number of corner members with strong resistance to bending in parallel, and each side of the arranged corner members has a
A required number of connecting holes are provided in a direction perpendicular to the arrangement direction, and a large number of corner members are loosely connected by connecting members smaller than the connecting holes, and both ends of the connected corner members are connected to adjacent vehicle bodies. Attach it to the floor,
Since the plate is made to be strong against bending in the longitudinal direction of the car body and easily deformed by torsion, it reduces the deflection of the plate when the car body rolls, and also prevents the car body from lifting off the floor. It can be prevented.

Therefore, it is possible to eliminate troubles such as tripping or getting one's feet caught in the part of the board, thereby increasing safety when passing through the board.
