Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting plate for connecting passages between vehicles.

[0002]

2. Description of the Related Art Conventionally, as a connecting passage connecting plate between connecting vehicles in a railway vehicle, as shown in FIG. 8 and FIG.
It is supported so as to be vertically rotatable by 4, and is regulated so as not to rotate downward from a horizontal posture, so that the front end portion of one of the single transfer plates 1 is superposed on the front end portion of the other transfer plate 2. There is something I did. The other transition plate 2 is composed of a main plate 5 and sub-plates 6 and 7, and the main plate 5 has a tip central portion 5a.
It is composed of a single plate that is cut in a rearward and rearward C-shape, and the sub-plates 6 and 7 are provided on the edge of the C-shape so that they can be rotated in the vertical direction by hinges 8 and 9. There is.

8 and 9 are of a type in which a hood forming a connecting passage is divided into two in the passage direction, and both divided hoods 10, 11 are separably connected by release side metal frames 12, 13. The transition plate 1 is provided on the vehicle 14 side, and the transition plate 2 is provided on the release side metal frame 12. Further, a bridging plate similar to the above is also installed between the other release-side metal frame 13 and the vehicle 14 ', and the same members as those mentioned above are denoted by the same reference numerals and the description thereof is omitted.

[0004]

In the above-mentioned conventional bridge plate, when a step is generated on both sides of the bridge plates 1 and 2 in rolling of the vehicle, the sub plates 6 and 7 are hinges 8 and 7.
It moves downward around 9 and closes the gaps on the side portions of the transition plates 1 and 2, but no countermeasure is taken when the vehicle is pitched or when the distance between the opposing end faces is reduced at the same time as the pitching. .

That is, since the main plate 5 of the transition plate 2 is formed of a single plate from the hinge 4 portion to the tip central portion 5a, when the pitching is 0, the state is as shown in FIG. Pitching occurs as shown in Fig. 10 (b) (Fig. 10 (b) shows the case where the pitching amount is 55 mm).
Then, when a step is generated between the hinges 3 and 4 of the two transition plates 1, one of the transition plates 1 as shown in FIG.
Of the main plate 5 of the other connecting plate 2 is largely separated from the upper surface of one of the connecting plates 1 and a large gap D is formed between them.
₁ occurs.

Further, when the distance between the opposing end faces is reduced in this pitching state, as shown in FIG. 10 (c), the tip central portion 1a of one of the connecting plates 1 is connected to the other connecting plate 2.
Of the other crossing plate 2 is pushed up further, and a larger gap D ₂ is generated between the central portion 5a of the tip of the main plate 5 and the upper surface of the one crossing plate 1.

When the passengers or the like walk in the connecting passage while the vehicle is running and the above-mentioned gaps D ₁ and D ₂ suddenly occur due to the pitching of the vehicle, the passengers or the like move to the tip of the cross plate. There is a risk that the user will trip over and fall, or put his foot between the gaps D ₁ and D ₂ and be caught by the two cross plates 1 and 2.

Further, in the structure having no sub plates 6 and 7 as described above, the above gap is generated over the entire length of the tip of the transition plate. Therefore, an object of the present invention is to provide a connecting passage connecting plate that solves the danger at the time of pitching, which has not been solved by the conventional structure.

[0009]

In order to solve the above-mentioned problems, the present invention is one in which the other crossing plate (27) is placed on the upper surface of one crossing plate (26), and the other crossing plate (27) is placed. It is characterized in that it is cut along the entire length in the direction orthogonal to the connecting passage direction and divided in the connecting passage direction, and the divided portions are connected rotatably in the vertical direction.

[0010]

When the pitching amount of the vehicle is large and the front end of one of the transition plates (26) pushes up the other transition plate (27), the divided front division plate of the other transition plate (27) ( However, 29) is bent and inclined downward due to its own weight, including the central portion of the tip thereof, and the gap between the tip portion of the dividing plate (29) and the upper surface of one of the transition plates (26) is closed.

Further, by increasing the number of divisions of the other connecting plate (27) in the connecting passage direction, the pitching amount of the vehicle is large, and the interval between the end faces of the connecting vehicle is reduced, so that one connecting plate ( 26) is the other bridge (2
Even when it sneaks into the inner part of 7), the other bridging plate (27) inclines at a gentle bending angle, and the gap between its tip and the upper surface of one bridging plate (26) is closed.

2 and 3 of the above-mentioned right side transition plate
The structure will be described in detail with reference to (a). One of the transition plates 26 is formed of a single rectangular plate, and the long side base portion thereof is on the vehicle 20 side.
Is arranged along the end surface of the vehicle, and the base side thereof is rotatably connected in the vertical direction by a horizontal hinge fitting 32 provided on the end surface of the vehicle 20, and the one crossing plate 26 is tilted around the hinge fitting 32. Is prepared to do. Further, the one crossing plate 26 is provided with a stopper (not shown) for preventing the downward rotation so that the upward movement is allowed from the horizontal posture in the figure, but the downward rotation is prevented. Has been. The tip 26a of the one connecting plate 26 is slightly bent downward.

The other connecting plate 27 is divided into a first dividing plate 28 and a second dividing plate 29 in the passage direction.
The base side of 8 is rotatably connected to the release side metal frame 24 by a hinge metal fitting 33 provided in the horizontal direction orthogonal to the passage direction, and is provided rotatably in the vertical direction around the hinge metal fitting 33. A tip portion of the first split plate 28 projects toward the one of the transition plates 26, and a front end face 28a thereof is linearly cut over the entire length in a direction orthogonal to the passage direction.

The base end 29a of the second dividing plate 29 is arranged along the tip surface 28a of the first dividing plate 28, and the second dividing plate 29 is perpendicular to the passage direction at the tip of the first dividing plate 28. It is provided rotatably in the vertical direction by a hinge fitting 34 provided in the horizontal direction. As shown in FIG. 2, the planar shape of the second dividing plate 29 is cut in a V-shape from the central end portion 29b toward the rear side.

These first division plate 28 and second division plate 29
As shown in FIG. 3A, when the pitching amount is 0 mm, the hinge fittings 32 and 33 are set to have a step so that they are placed on one of the horizontal crossover plates 26 in a horizontal posture. There is.

35 is a seat 36 on the lower surface of the first dividing plate 28.
The reference numeral 37 designates a pick-up plate fixed via the seat 38, and the reference numeral 37 designates a pick-up plate fixed on the lower surface of the second divided plate 29 via the seat 38, respectively. Since such a slot plate 37 and a seat 38 form a slight gap between the second split plate 29 and one of the transition plates 26, the tip central portion 29b of the second split plate 29 is bent slightly downward to move the tip center. Part 29
The gap between b and one of the transition plates 26 is made small.

As shown in FIG. 2, the sub plates 30 and 31 are rotatably provided by hinge metal fittings 39 and 40 on both sides of the second split plate 29 which are cut in a V shape. Also,
As shown in FIG. 2, both sides 30a, 3 of the sub plates 30, 31 are

In FIGS. 1 and 2, 41 and 42 are pressing devices for pressing both release side metal frames 24 and 25 against each other.
3 and 44 are side panels, and 45 and 46 are ceiling panels.
Next, the operation of this embodiment will be described.

When there is no pitching amount between the vehicles or between the vehicle and the release side metal frame, as shown in FIG. 3A, the first split plate 28 of the other cross plate 27 and the first split plate 28 of the other cross plate 27 are arranged on one horizontal cross plate 26. The two-division plate 29 is placed horizontally. Therefore, the central end portion 29b of the second split plate 29 is close to the upper surface of one of the transition plates 26. The tips of the sub plates 30 and 31 are also in contact with one of the transition plates 26.

When a large amount of pitching occurs between vehicles or between the vehicle and the release side metal frame, as shown in FIG. 3 (b), for example, as shown in FIG. When the hinge metal fitting 32 moves upward (in FIG. 3B, the pitching amount is 55 mm), as shown in FIG.
The first split plate 2 on the other crossing plate 27 by the tip of the
The tip portion of 8 is pushed up, and the first divided plate 28 moves up around the hinge fitting 33. At this time, the second split plate 29 is inclined by its own weight so that the front part moves downward about the hinge metal fitting 34, and the state where the pick-up plate 37 is in contact with one of the transition plates 26 is maintained. Therefore, the central portion 29b of the tip maintains a closed state close to the upper surface of one of the transition plates 26. In addition, the sub plates 30 and 31 also incline downward, and their tips are in contact with and closed on one of the transition plates 26.

Therefore, a large gap is not generated between the upper surface of the one connecting plate 26 and the tip end portion of the other connecting plate 27, and passengers or the like are prevented from tripping over the connecting plate or their feet being caught between the connecting plates. .

Also, in the above pitching state, FIG.
As shown in FIG. 3, when the vehicle interval or the distance between the vehicle and the release side metal frame is reduced, as shown in FIG. 3C, the first division of the other connecting plate 27 by the tip of one connecting plate 26 is performed. The plate 28 is further pushed up and its first division plate 28
Is spaced apart from the upper surface of one of the transition plates 26.
However, the tip portion of the second split plate 29 moves downward due to its own weight in the same manner as described above, and closes the gap between the second split plate 29 and the upper surface of one of the transition plates 26. In addition, the sub plates 30 and 31 also incline downward, and their tips are in contact with and closed on one of the transition plates 26.

Therefore, similarly to the above, it is possible to prevent passengers or the like from tripping over the crossing board or the foot being caught between the crossing boards. Next, a second embodiment of the present invention shown in FIG. 4 will be described.

In the second embodiment, one of the crossover plates 26 in the first embodiment is set so that the tip thereof has an inclination angle α which is slightly lowered from the horizontal plane when in the laid posture. Since the other structure is the same as that of the first embodiment, the same portions as those described above are designated by the same reference numerals and the description thereof will be omitted.

According to the second embodiment, as shown in FIG. 4 (c), in the same large pitching state as in FIG. 3 (c) of the above-mentioned second embodiment, the distance between the vehicle flanks or the vehicle is released. When the distance between the side metal frames is reduced, one of the connecting plates 26
The front portion of is located below the first embodiment. Therefore, the push-up amount of the first split plate 28 on the other transition plate 27 is smaller than that of the first embodiment, and the distance between the tip of the first split plate 28 and the one transition plate 26 is also reduced. . Therefore, the first division plate 28 and the second
The height of the bending with the dividing plate 29 is also reduced, and the above-mentioned degree of danger is further reduced.

Other functions and effects of the second embodiment are similar to those of the first embodiment. Next, a third embodiment of the present invention shown in FIGS. 5 to 7 will be described. In the third embodiment, the first divided plate 28 of the other transition plate 27 in the first embodiment is further divided into two in the passage direction to provide a third divided plate 28a, and the third divided plate 28a is released. The side metal frame 24 is connected to the side metal frame 24 by the hinge metal fittings 33 as described above.

Further, the first division plate 28 and the third division plate 2
8a is rotatably connected by a horizontal hinge fitting 47 in a direction orthogonal to the passage direction. Further, posture holding members 48 and 49 are fixed to the upper surfaces of the first divided plate 28 and the third divided plate 28a so as to face each other at both sides of the hinge fitting 47. The posture holding members 48 and 49 are in contact with each other when the plates 28 and 28a are in a straight line state, and are in contact with each other when the plates 28 and 28a are in a straight line, and are separated from each other when bent downward around the hinge metal fitting 47. 49a is formed to prevent upward bending from both plates 28 and 28a in a straight line state, and allows only downward bending. Since the other structure is the same as that of the first embodiment, the same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

According to the third embodiment, as shown in FIG. 7 (b), the first division is performed in a large pitching state and when the vehicle end face distance or the distance between the vehicle and the release side metal frame is reduced. The plate 28 and the third divided plate 28a are bent as shown in the figure, and the other connecting plate 27 is bent into a gentler mountain shape as compared with the above-mentioned embodiment, and the risk is reduced. Further, the posture maintaining members 48, 49 allow the both plates 28, 28a to be normally operated.
Since mutual straightness is maintained, there is no obstacle for passengers to walk.

Other functions and effects of the third embodiment are similar to those of the first embodiment. In addition, each of the above embodiments,
This is an example in which the connecting hood is divided into two, and a cross plate is provided between the release side hood fitting and the vehicle.
In the type where one connecting hood is installed between vehicles,
The one crossover plate 26 may be provided on one vehicle end face, and the other crossover plate 27 may be provided on the other vehicle end face.

Further, the present invention may be applied to a transition plate which does not include the sub plates 30 and 31 in the above embodiment.
