Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height adjusting device for a side entrance / exit of a railway vehicle for passenger transportation, and a step between the platform and the entrance / exit of the vehicle is compensated by the adjusting device to facilitate passengers getting on and off. Is something that can be.

[0002]

2. Description of the Related Art The height from the rail surface of the platform of each railway station in Japan is about 760 mm, 920 mm,
There are 3 types of 1100 mm, but the height of the deck of the vehicle used exclusively for commuting in urban areas is approximately 1100 m.
It has become m. Therefore, the height in urban areas is 1
When stopped on a 100 mm platform, the so-called deck of the vehicle or a vehicle without a deck has no problem because the height of the doorway of the passenger compartment floor (hereinafter also referred to as "deck") is almost the same as the platform, Especially when stopping on a 760 mm platform in the suburbs or rural areas, the step is large, which makes it inconvenient to get on and off. Also,
Some vehicles for rural areas have low-floor steps only at the entrance and exit, but conversely, if this vehicle gets into an urban area,
The 100 mm height platform is higher, which is not legally permitted. In order to eliminate this inconvenience, some work is being done to raise the entire platform to a height of 920 mm or 1100 mm, but there is a problem in terms of cost to carry out this work at all stops.

[0003]

SUMMARY OF THE INVENTION The present invention is based on the idea of adjusting the height of the entrance / exit of a vehicle deck, rather than adjusting the height on the platform side in order to compensate for the step between the platform and the entrance / exit of the vehicle. The problem is to devise a vehicle entrance / exit height adjusting mechanism that can be installed at low cost, can be maintained at low cost, and can be attached to all entrances / exits of the vehicle.

[0004]

[Means taken for solving the problems] Means taken for solving the above problems are configured by the following (a) and (b) on the premise of a height adjusting device for an entrance / exit of a railway vehicle for passenger transportation. It is what is done. (A) A deck with a height of approximately 1100 mm has a low floor, and a side sliding door rail is provided on the low floor, and (b) a step plate that covers the low floor at the height of the deck is placed with a guide rail. It was supported freely and the drive device for the step board was installed under the floor of the deck.

[0005]

When the vehicle is stopped on the platform having a height of 1100 mm, the low floor is covered with the step plate. Since the step plate is almost the same height as the platform, there is no obstacle for getting on and off. Absent. Height 920
When the vehicle is stopped on the mm platform, the step plate is retracted under the floor of the deck by the drive device provided under the floor of the deck. The low floor is much lower than the deck, and the height is 920mm above the platform.
Is almost equal to. Therefore, the step between the platform and the entrance / exit is almost eliminated, and it is possible to get on and off without trouble. Even when the vehicle is stopped on the platform having a height of 760 mm, the step plate is retracted under the floor by the drive device provided under the floor of the deck. The height of the low floor is somewhat higher than that of the platform, but this step is lower than the height of a normal staircase. Therefore, although there is inconvenience as compared with the case where the height of the platform and the height of the entrance / exit of the deck are almost the same, getting on / off is easy.

[0006]

Embodiment 1 Embodiment 1 is that the step between the low floor and the deck is 150 to 180 mm. The entrance is lowered by 150 to 180 mm from the deck, and the step is smaller than the normal step of one stair, so it is easy to go up and down from the deck to the low floor without any hindrance. In addition, there are almost 16 steps between the 760 mm high platform and the low floor.
Since it is about 0 to 200 mm, there is no practical problem in getting on and off the 760 mm platform.

[0007]

[Embodiment 2] Embodiment 2 is that the direction in which the step plate is moved in and out is the direction in which the passenger exits and exits.

[0008]

[Embodiment 3] Embodiment 3 is that the step plate is oriented in a direction perpendicular to the direction in which the passenger exits and exits.

[0009]

Embodiment 4 Embodiment 4 is that the driving means for the step plate is a pneumatic cylinder.

[0010]

Fifth Embodiment In a fifth embodiment, a sensor is provided above the low floor to detect a passenger or luggage on the step board or the low floor, and when a passenger or luggage on the step board or the low floor or luggage is detected, That is, the entrance and exit drive was disabled.

[0011]

[Embodiment 6] Embodiment 6 is provided with the above-mentioned low floor position sensor, and the side sliding door is opened and closed when the step plate is pushed out to cover the low floor or when the step plate is completely retracted. That's what I did.

EXAMPLES Next, examples will be described. The relationship between the platform of the vehicle stopped on the platform and the platform is shown in Fig. 1. The height of the vehicle deck is almost the same as that of the platform P1 having a height of 1100 mm,
The maximum distance x between the platform and the entrance of the vehicle deck is about 160 mm. On the other hand, when the step portion A is provided at the entrance of the vehicle deck, the depth width of the step portion A is 260 m.
must be at least m. In this embodiment, the low floor portion A1 has a width B1 of 1300 mm and a depth width B2 of 300 m.
m. In this embodiment, the step plate 1 covering the low floor portion A1 is used.
Is an example in which the step plate 1 can be freely moved in and out in the front-rear direction (moving direction) of the low floor portion A1, and the width of the step plate 1 is almost the same as the width of the low floor portion A1, but the depth width b is 250 mm. A pair of front and rear rollers 1a are provided on both left and right sides of the step plate 1.
Is provided and is slidably supported by the left and right guide rails 3 provided under the floor of the deck 2. It is necessary to increase the rigidity of the step plate 1 with respect to the weight so that the step plate 1 is not largely bent by the weight of the passenger. For that purpose, the step plate 1 may be a double-skin type member (a hollow member having a structure in which front and back plates are connected by ribs), or a reinforcing rib extending in the depth direction may be provided on the lower surface of the plate member. Further, a leg is provided on the lower surface of the front end of the step plate 1, and a small wheel (such as a caster wheel) is provided on the leg so that the leg rolls on a low floor.
The front end of the step plate 1 may be supported by the legs. A pneumatic cylinder 4 is provided below the floor of the deck 2, and its piston rod 4a is connected to the end of the step plate 1.

The floor of the low floor portion A1, that is, 140 mm lower than the low floor 5 and the deck 2, guides the side sliding door 7 by a rail 6 provided at the entrance of the low floor 5. Low floor A
A light projector D1 and a light receiver D2 are provided on both left and right walls of the sensor 1 to form a sensor S1. Further, a sensor S2 including a light projector and a light receiver is provided at a height of about 1.5 mm on the side wall of the deck entrance / exit. The presence of passengers or luggage at the doorway of the deck is detected by the sensors S1 and S2, and the pneumatic cylinder 4 is detected by this detection signal.
The operation of the control circuit of is interlocked,
The pneumatic cylinder 4 is expanded and contracted on condition that the detection signal is not transmitted. Further, in this example, the step plate 1 is normally pushed out to cover the low floor 5, and when the vehicle is stopped on a platform having a height of 920 mm and 760 mm, the step plate 1 is controlled so as to be retracted before stopping. It is not preferable for safety that the side sliding door 7 is opened and closed during the movement of the step plate 1 or the step plate 1 is moved in and out after the side sliding door 7 is released. For this reason, the side sliding door 7 is moved during the movement of the step board 1 in and out.
Of the pneumatic cylinder 4 and the side sliding door are controlled so that the stepping plate 1 does not open and close and that the step plate 1 is prevented from moving after the side sliding door is released. In the embodiment shown in FIG. 4, the step board 11 is arranged under the floor of the deck so that the step board 11 enters and exits in the width direction of the low floor portion (lateral direction of the entrance and exit). If a pneumatic cylinder is used as the driving means, it can be fluidly locked, so that no separate means for fixing the step plate at the pushing position and the retracting position is required. The pneumatic cylinder may be a double-action type (operates with air pressure in both directions of expansion and contraction), or a cylinder with a bias spring installed (for example, a bias spring that biases the piston in the pushing direction, It may be one that retracts the piston rod by air pressure against the bias spring). An electric motor can be used as the driving means for the step plate. In this case, a rack gear may be provided on the lower surface of the step plate and the rack gear may be driven by a pinion of an electric motor. In addition, since the electric motor is a motor with a brake and the brake is normally ON (brake is operated when the electric motor is not operated), the step plate can be fixed by the electric motor at any of the retracted position and the pushed out position. There is no need for separate means for fixing the step plate in the push position and the retract position.

[0014]

As described above, the above-mentioned deck is provided with an adjusting device for adjusting the height of the entrance and exit of the deck of the vehicle, and the step plate is driven to cover the low floor portion provided on the deck, or Since the height of the entrance and exit is adjusted by releasing the opening, the adjusting device is extremely simple and its operation is highly reliable. Therefore, the height adjusting device of the entrance / exit can be installed at low cost, and the maintenance cost thereof is also low.
