DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boarding / alighting assist device for eliminating a gap and a step between a vehicle entrance and a platform.

[0002]

2. Description of the Related Art Heretofore, since the existence of a gap between a train and a platform is dangerous, a device for solving the problem has been proposed. For example, JP-A-60-222360
Gazette, Japanese Patent Laid-Open No. 2-204160,
No. 170259, and the like. These devices use a cylinder or motor actuator to drive a step board that closes the gap, and store the step board in the storage position when passengers do not get on and off the train, while using the step position when passengers get on and off the train. Then, a step plate is made to appear to close the gap. The drive mechanisms of the step plates are different from each other, but in any case, the step plates close the gaps with the upper surface being horizontal at the use position.

[0003] However, there are often gaps as well as gaps between the platform and the vehicle floor. For this reason, in the related art, the gap is closed when the step plate is at the use position, but there is a disadvantage due to a step. Specifically, even at the latest station, the vehicle side is at least 50 mm higher than the platform surface, and it is expected that the level difference will be even greater at stations that have not been improved (bulged).

[0004] In addition, such a gap exists at least 50 mm even at a station having a straight track, and becomes larger at a station having a curved track. Since such gaps and steps exist, even if a wheelchair user tries to get on and off the train, he / she cannot get on and off by himself. Therefore, the wheelchair user is forced to get on and off the wheelchair by the station attendant and the attendant. For this reason, there is a problem that not only is it difficult for a wheelchair user to get on and off the train freely, but also the physical load on the attendant and the helper is large.

In order to solve such a problem, an apparatus for eliminating the above-mentioned step is disclosed in, for example, Japanese Patent Laid-Open No. 7-108.
926 or JP-A-7-108927. In these devices, the tipping edge is located at the track side edge of the platform corresponding to the entrance of the stopped vehicle, and is installed so that the upper surface coincides with the upper surface of the platform, and the tilting device arranged on the lower side A first slope plate that is tilted so that the leading edge rises, and a tip that is supported by the first slope plate and protruded by an advance / retreat driving device so as to extend the first slope plate toward the leading end. A second slope plate having an edge approaching a platform-side edge of the floor of the entrance / exit is adopted.

[0006]

However, the above-described device requires two systems of driving devices, a tilting device and an advancing / retracting driving device, so that the structure of the device is complicated and the cost is increased. is there. In addition, since a motor is used in each of the driving devices in the above-described conventional device, there is a possibility that normal operation cannot be performed due to being wet with water. In particular, train platforms are not always roofed and are often exposed to rain. Therefore, it is desired to construct a system that is not easily affected by being wet with water. In addition, in the above-described apparatus, when used, the operator must operate two switches, a switch for tilting the first slope plate and a switch for projecting the second slope plate, skillfully. It is desirable to simplify the operation system as much as possible.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and by rotating an arm by a single drive device, a first plate-like member is raised in one operation and a second plate-like member is raised. It is an object of the present invention to provide a getting-on / off assistance device capable of extending a vehicle. It is another object of the present invention to provide a getting-on / off assistance device that can be quickly and reliably operated by a simple operation, is resistant to wetness, and can reduce manufacturing costs.

[0008]

According to a first aspect of the present invention, there is provided a boarding / alighting assisting device which is buried at an edge of a platform, and a plate-like body is formed so as to eliminate a gap and a step between a vehicle entrance and a platform during use. In the getting on and off assisting device,

A second engaging means for engaging with the means, and a driving means for rotating the arm forward or backward,
The arm stands up to the track side when used, and tilts to the opposite side of the track during standby.

As described above, when the arm stands up while rotating to the track side during use, the contact means provided on the arm raises the first plate-like body and the second engagement means provided on the arm. Pushes the second plate-like body toward the vehicle entrance while engaging with the first engagement means, so that it is possible to shift from the standby state to the use state only by rotating the arm. For this reason, the drive device only needs to provide one system for rotating the arm, and while simplifying the structure,
Manufacturing costs can be reduced. Furthermore, since the operation can be shifted from the standby state to the use state in one operation, the operation by the operator is simplified, and the operation can be performed quickly and reliably.

According to a second aspect of the present invention, there is provided the getting-on / off assist device according to the first aspect, further comprising a stopper which abuts on the arm at a position where the arm is inclined to the track side from the upright position during use.

There is no. That is, since the arm is supported by the stopper in a state inclined to the track side from the upright position, unless the arm receives a rotational force such that the arm rotates in a direction opposite to the track side, the arm exceeds the upright position and There is no rotation in the direction opposite to the side, and the first plate-like body and the second plate-like body do not descend. As a result, it is possible for the passenger to get on and off the vehicle safely.

According to a third aspect of the present invention, in the getting-on / off assistance device according to the first or second aspect, the abutment means and the second engagement means include a roller.

[0013] With this configuration, the roller rotates when the contact means comes into contact with the first plate-shaped body, so that the operation of pushing up the first plate-shaped body by the arm can be performed smoothly. Further, since the roller rotates when the second engagement means pushes out the second plate-like body while engaging with the first engagement means,
The operation of pushing out the plate-like body can be performed smoothly.

According to a fourth aspect of the present invention, in the getting-on / off assist device according to any one of the first to third aspects, the first engagement means is a rail having a substantially U-shaped cross section and extending vertically. Take the configuration.

With this arrangement, the second engaging means rides on the rail when the first plate-like body and the second plate-like body are put on the arm, so that the first plate-like body and the second plate-like body are placed on the arm. The second engagement means can be engaged with the first engagement means only by putting on. When the second engaging means includes a roller, the roller rotates on the rail, so that the second engaging means smoothly pushes out the second plate-like body while engaging with the first engaging means. Can be performed.

According to a fifth aspect of the present invention, in the getting on / off auxiliary device according to any one of the first to fourth aspects, the driving means is a rotary actuator.

Thus, since a rotational force for rotating the arm by the pressure of the air can be obtained, there is no possibility that a trouble due to water occurs when the motor is used.
In addition, when a motor is used as a drive device, the amount of rotation of the arm must be electrically controlled, and a circuit for that purpose is required, which complicates the device configuration. Therefore, a circuit for controlling the amount of rotation of the arm is not required, and the configuration of the device can be simplified. As a result, the durability of the getting-on / off assist device can be enhanced, and a proper operation can always be performed even on a platform exposed to rain.

According to a sixth aspect of the present invention, in the getting-on / off assistance device according to any one of the first to fifth aspects, the second plate-like body further includes a buffer means at a vehicle-side tip portion.

With this configuration, even if the second plate-shaped body extending to the vehicle entrance is in contact with the vehicle body, the shock absorbing means reduces the impact, so that the vehicle body can be prevented from being damaged. . Further, by providing the buffer means in this way, it is possible to enhance safety for humans.

According to a seventh aspect of the present invention, in the getting-on / off assistance device according to any one of the first to sixth aspects, the length of the first plate-shaped body in the width direction is equivalent to one tile block of the platform. The configuration is substantially the same as the length.

As described above, the length of the first plate-shaped member in the width direction is substantially the same as the length of one tile block of the platform. Therefore, when the getting-on / off assist device according to the present invention is installed on the platform, The tile block at the installation location can be peeled off, and the boarding / alighting assist device can be buried in the removed area in a good format. As a result, workability is improved, and it is possible to avoid the occurrence of irregularities around the getting-on / off assist device after the installation, and to maintain a good appearance.

According to an eighth aspect of the present invention, in the getting-on / off assistance device according to any one of the first to seventh aspects, at least one of a water-repellent treatment and a non-slip treatment is applied to a surface of the first plate-shaped body. Take the configuration that has been.

Thus, it is possible to prevent a passenger passing over the getting-on / off assistance device from slipping on his / her feet or slipping on wheels of a wheelchair.

[0024]

BEST MODE FOR CARRYING OUT THE INVENTION The present inventors use two types of driving devices, a tilting device for raising a first plate-shaped member and an advancing / retracting driving device for extending a second plate-shaped member. Focusing on the point that the operation becomes troublesome due to the necessity of two systems of switches, and the rotation of the arm by one system of driving device raises the first plate-like body in one operation, The present inventors have found that two plate-like bodies can be extended, and have accomplished the present invention.

That is, the present invention provides a first plate-shaped member provided at the edge of the platform and rotatably supported around an end opposite to the track, and slidably mounted on the back surface of the first plate-shaped member. A second plate-shaped member provided in the first plate-shaped member and extending from the end of the first plate-shaped member on the track side to the vehicle entrance at the time of use; a first engaging means provided on the second plate-shaped member; At least one arm rotatably supported at a position facing the back surface of the plate-like body, a contact means provided on the arm, which is in contact with the back surface of the first plate-like body, and a rotation center of the arm from the contact means.

As a result, the present inventors have made it possible to shift the getting-on / off assist device from the standby state to the use state only by rotating the arm. Furthermore, while simplifying the structure of the device and reducing the manufacturing cost, the operator can quickly and reliably operate the getting-on / off assist device with a simple operation.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the drawings, the same elements are denoted by the same reference numerals, and redundant description will be omitted. Also, the dimensional ratios in the drawings do not always match those described.

FIG. 1 is a cross-sectional view of a getting-on / off assist device according to an embodiment of the present invention, and FIG.

a is removably installed on a buried base 3b buried in the platform 2. The buried base 3b is directly fixed to the platform 2, and the buried base 3b is
It is placed on top and fixed. As described above, since the base 3a can be detached from the embedded base 3b as necessary, maintenance is easy.

The base 3a is in a standby state and the first slope plate 5
Buried base 3 buried at the edge of platform 2 such that the position of the upper surface of
b. Bolts 9 are used to fix the base 3a to the buried base 3b and to fix the buried base 3b to the platform 2. Further, a hose guide 10 for passing a hose (not shown) connected to the drive mechanism 7 is provided at the bottom of the embedded base 3b.

The first slope plate 5 is connected to the base 3 by the shaft 4.
a so as to be rotatable, and in a standby state, become substantially horizontal and cover the base 3a. At this time, the height of the surface 5a of the first slope plate 5 substantially matches the height of the platform surface 2a. In use, the first slope plate 5
Is pushed up by a drive mechanism described later, and rotates leftward in FIG. Thereby, as shown by the dotted line in FIG. 1, the line side end 5b rises.

The length of the first slope plate 5 in the width direction is substantially the same as the length of one tile block of the platform. As described above, since the length in the width direction of the first slope plate 5 is substantially the same as the length of one tile block of the platform, when the getting-on / off assist device according to the present invention is installed on the platform, The tile block can be peeled off, and the getting-on / off assistance device can be buried in the removed portion in a good shape. As a result, workability is improved, and it is possible to avoid the occurrence of irregularities around the getting-on / off assist device after the installation, and to maintain a good appearance.

Further, on the surface 5a of the first slope plate 5,
At least one of a water-repellent treatment and a non-slip treatment is performed. Thus, it is possible to prevent a passenger passing on the getting-on / off assistance device from slipping on a foot or a wheel of a wheelchair.

The back surface 5c of the first slope plate 5, that is,
On the surface of the first slope plate 5 facing the base 3a, FIG.
, A second slope plate 6 is provided so as to freely slide in the left-right direction. The second slope plate 6 is stored in the lower surface of the first slope plate 5 at the time of standby, and in use, the first slope plate 5 rises and the line side of the first slope plate 5 as shown by a dotted line in FIG. It extends from the end 5b. That is, the second slope plate 6 functions to extend the length of the first slope plate 5.

It is also possible to adopt a configuration in which a buffer means such as rubber or urethane is provided at the vehicle-side end of the second slope plate 6. As a result, the second vehicle extending to the vehicle entrance
Even if the slope plate 6 comes into contact with the body of the vehicle, the shock absorbing means reduces the impact, so that the body of the vehicle can be prevented from being damaged. Further, by providing the buffer means in this way, it is possible to enhance safety for humans.

The back surface 6a of the second slope plate 6, ie,
Rails 6b as first engagement means are provided at both ends in the width direction of the surface of the second slope plate 6 facing the base. The rail 6b has a substantially U-shaped cross section and is formed to extend in the up-down direction, and engages with a urethane roller as second engagement means described later.

The drive mechanism 7 is provided in parallel with the rotary actuator 11 for generating a rotational force by compressed air and in the width direction of the base 3a.
And a gear box 13 having a plurality of gears for transmitting to the rotating shaft 12, and an arm 14 rotatably supported by the rotating shaft 12.

The rotary actuator 11 is connected to an air compressor (not shown) via a hose (not shown) passing through a hose guide 10. The rotary actuator 11 receives a supply of compressed air from the air compressor and rotates forward or backward within a predetermined angle. This rotational force is transmitted through the gearbox 13 to the rotating shaft 1.
2 and the arm 14 rotates within a predetermined angle.
As described above, since the rotational force for rotating the arm 14 can be obtained by the pressure of the air, there is no possibility that a trouble caused by water occurs when the motor is used. When a motor is used as a driving device, it is necessary to electrically control the amount of rotation of the arm 14, and a circuit for that purpose is required, which complicates the device configuration. Since it is determined, a circuit for controlling the rotation amount of the arm 14 is not required, and the configuration of the device can be simplified. As a result, the durability of the getting-on / off assist device can be enhanced, and a proper operation can always be performed even on a platform exposed to rain.

Next, the arm 14 will be described with reference to FIGS.
3 and FIG. 4 in addition to FIG. 3 is a perspective view showing a state in which the first slope plate 5 is opened in the getting-on / off assist device in a standby state, and FIG. 4 is a view showing a state in which the first slope plate 5 is opened in the getting-on / off assist device in use. FIG.

One arm 14 is provided at each end of the rotary shaft 12 so as to sandwich the rotary actuator 11, and rotates together with the rotary shaft 12. Arm 1
Numeral 4 is tilted so as to be located on the opposite side of the track during standby, that is, on the left side of the rotating shaft 12 in FIG. Also,
As an abutting means, a urethane roller 14b abutting against the back surface 5c of the first slope plate 5 is provided at an end 14a of the arm 14.
Is provided. When the rotating shaft 12 rotates rightward in FIG. 1 during use, the arm 14 rotates so as to stand upright in FIG. As a result, the urethane roller 14b provided at the end 14a of the arm 14 pushes up the first slope plate 5 from below, so that the first slope plate 5 rotates around the shaft 4 to the left in the figure. As a result, the first slope plate 5
Of the track side 5b rises.

The arm 14 is provided with a urethane roller 1 as a second engaging means at a position closer to the center of rotation than the end 14a.
4c is provided. This urethane roller 14c is
It engages with a rail 6b provided on the second slope plate 6.
For this reason, when the rotating shaft 12 rotates rightward in FIG. 1 during use, the urethane roller 14 provided on the arm 14 rotates while the arm 14 rotates so as to rise rightward in FIG.
c presses the rail 6b toward the track side. Thereby, the second
The slope plate 6 moves rightward in FIG. 1 and extends from the line end 5b of the first slope plate 5.

As described above, since the urethane roller 14b for pushing up the first slope plate 5 and the urethane roller 14c for extending the second slope plate 6 are provided on the arm 14, rotation of the arm 14 allows one operation. It is possible to push up the first slope plate 5 and extend the second slope plate 6.

When the urethane roller 14b contacts the first slope plate 5, the roller rotates.
4 allows the operation of pushing up the first slope plate 5 to be performed smoothly. Further, when the urethane roller 14c pushes the second slope plate 6 while engaging with the rail 6b, the roller rotates, so that the operation of pushing the second slope plate 6 can be performed smoothly.

Also, the rail 6b as the first engagement means
Has a substantially U-shaped cross section and extends in the vertical direction. When the first slope plate 5 and the second slope plate 6 are put on the arm 14, the urethane roller 14c rides on the rail 6b. 5 and the second slope plate 6 to the arm 1
4 and the urethane roller 14c is placed on the rail 6b.
Can be engaged.

In this embodiment, as the first engaging means, a rail 6b having a substantially U-shaped cross section and extending in the vertical direction is used.
However, the present invention is not limited to this. That is, the first engagement means may have another form, for example, an L-shaped cross section of the rail,
Alternatively, the cross section may be a half-moon shape, and other shapes are also possible. Although the urethane roller 14c has been described as an example of the second engagement means, the present invention is not limited to this. That is, it is also possible to use another form, for example, a cam follower or a pin, as the second engagement means.

A stopper 15 is provided at a position slightly past the upright position on the rotation path of the arm 14. Arm 1
4 rotates so as to stand rightward in FIG. 1 during use, but stops rotating when it comes into contact with the stopper 15. As described above, since the arm 14 comes into contact with the stopper 15 at a position inclined to the track side from the upright position during use, the first slope plate 5 and the second slope plate 6 may descend when a passenger is on the vehicle. Absent. That is, since the arm 14 is supported by the stopper 15 in a state inclined to the track side from the upright position, as long as the arm 14 does not receive a rotational force that rotates in the direction opposite to the track side, the arm 14 is in the upright position. It does not rotate in the opposite direction to the track side beyond. Therefore, the first slope plate 5 and the second slope plate 6
Does not descend during use, and passengers can safely get on and off.

The base 3a is provided with a shock absorber 16 for abutting on the first slope plate 5 during standby to absorb shock. This shock absorber 1
According to 6, when returning from the use state to the standby state, the impact when the first slope plate 5 collides with the base 3a can be reduced, and generation of vibration can be prevented. In addition, during standby, it is possible to absorb the impact applied to the getting-on / off assistance device 1 when the passenger is placed on the first slope plate 5. Further, when a plurality of the getting-on / off assist devices 1 are provided in series, the height of the first slope plate 5 of each device can be made uniform by adjusting the contact position of the shock absorber 16 up and down.

Next, the operation of the getting-on / off assist device according to one embodiment of the present invention configured as described above will be described with reference to FIGS. Here, an example in which six getting-on / off assist devices 1 are provided in series will be described.

FIG. 5 is a perspective view showing a standby state of the getting-on / off assist device according to the present embodiment. As shown in FIG. 5, at the time of standby, the first slope plate 5 covers the entire other components including the base 3a. Also, the first slope plate 5 is
It is almost horizontal and forms the same plane as the surface of the platform. For this reason, at the time of standby, the
Will not interfere with passenger traffic. In addition, since the second slope plate 6 is stored on the lower surface of the first slope plate 5 during standby, the second slope plate 6 does not protrude from the edge of the platform, and therefore does not obstruct the passage of the train.

FIGS. 6 and 7 are views showing the use state of the getting-on / off assist device according to the present embodiment. When the operator presses one switch (not shown), the first slope plate 5 rises, and the second slope plate 6 extends from the line end 5b. Since an air compressor that generates a strong force is used for this driving force, the time required for transition from the standby state to the use state is about one second. Since the first slope plate 5 is raised and the second slope plate 6 extends to the entrance 21 of the train 20, gaps and steps existing between the entrance and exit of the train and the platform are eliminated. Since the getting-on / off assist device according to the present embodiment can shift from the standby state to the use state in one operation, the operator only needs to press the switch once, and the two-system drive mechanism is operated as in the related art. You don't have to do much. FIG. 7 shows a state in which the getting-on / off assistance device 1 has just been used by an operation of a conductor, a station attendant, or the like. As shown in FIG. 7, the getting-on / off assistance device 1 according to the present invention may be provided at a position corresponding to, for example, the getting-on / off opening 21 closest to the conductor compartment. Train 2
You may provide so that it may correspond to all the entrances and exits of 0.

FIG. 8 is a view showing a switch for operating the getting-on / off assist device according to one embodiment of the present invention.
The switch 80 can transmit a signal to the getting-on / off assistance device 1 by wire, wirelessly, or by infrared rays. In the present embodiment, a switch that performs wireless transmission is not necessary because the wireless switch does not require construction work such as wiring installation on the platform 2 and a wired switch may cause mischief on the platform 2. 80 is exemplified. The switch 80 includes a monitor LED 81, an A button 82, and a B button 83. The A button 82 is a button for generating a signal for shifting the getting-on / off assist device 1 from the standby state to the use state. The B button 83 is a button for generating a signal for shifting the getting-on / off assist device 1 from the use state to the standby state. The operator can operate the getting-on / off assistance device 1 by pressing one of these buttons. Therefore, unlike the conventional method, many operations are not required.

As described above, when the arm stands up while rotating to the track side during use, the abutting means provided on the arm raises the first plate-like body and the second engagement provided on the arm. Since the means pushes the second plate-shaped body toward the vehicle entrance while engaging with the first engaging means, it is possible to shift from the standby state to the use state only by rotating the arm. For this reason, the driving device only needs to provide one system for rotating the arm, so that the structure can be simplified and the manufacturing cost can be reduced. Furthermore, since the operation can be shifted from the standby state to the use state in one operation, the operation by the operator is simplified, and the operation can be performed quickly and reliably.
