Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a step member of a platform, and more specifically, to a step member of a platform, which is mounted on a lateral side edge in a longitudinal direction of the platform, and is located between a vehicle stopped at a station yard and the side edge. The present invention relates to a step member for narrowing the gap.

[0002]

2. Description of the Related Art Generally, it is desirable to construct a station platform in a straight line as much as possible, but there is no choice but to construct it in a curved shape such as an arc or an S-shape depending on the location conditions of the station and other conditions. In some cases. Here, when a railway vehicle enters and stops on a curved platform, as is well known, due to the characteristics of the vehicle, a gap is defined between the vehicle and the platform. The opening width of this gap becomes larger as the radius of curvature of the curve given to the platform becomes smaller.

When the gap is defined between the vehicle and the platform in this way, it not only causes inconvenience to passengers getting on and off the stopped vehicle, but also especially for infants and visually impaired persons. There is a fear that a drunk person may get injured by getting his foot caught in the gap. In addition, if a passenger accidentally drops a carrying item such as a bag, it may fall under the platform (on the track) through the gap. Furthermore, there is a case where people with disabilities who use wheelchairs cannot get on and off the vehicle.

Therefore, in order to avoid the above-mentioned inconvenience,
For example, as shown in FIG. 9, a vehicle that has a separately formed strip-shaped step member 16 attached to a side edge 12 in the longitudinal direction of the platform 10 (an edge directed toward the track side) and stops in the station yard Measures are taken to narrow the gap defined between 14 and the platform 10. Separately from this, for example, a platform step device disclosed in Japanese Patent Laid-Open No. 2001-328529 is installed in the platform 10 to narrow the gap defined between the vehicle 14 and the platform 10. Methods have also been proposed.

[0005]

By the way, most of the conventional step members 16 shown in FIG. 9 are wooden plate members or concrete plate members formed into a required shape. . However, since the step member 16 made of wood or concrete has almost no flexibility and elasticity, it is difficult to mount the step member 16 on the side edge 12 of the curved platform 10. However, there is an inherent defect that the side edge 12 cannot be closely followed. Therefore, it is necessary to make the step member 16 into a curved shape that matches the curve shape of the platform 10 at the time of preforming or post-forming processing, or to repair the platform 10 according to the shape of the step member 16. Caused the molding cost and construction cost to increase significantly. Further, since the step member 16 is rigid, an uncomfortable contact sound is generated when the stopped vehicle 14 comes into contact with the step member 16 due to the rolling of passengers getting on and off.
There were also inconveniences such as scratches and paint peeling on the side surface of the vehicle body of the vehicle 14.

Further, the conventional step member 16 is adjusted in position so that the upper surface thereof is the same as or slightly lower than the floor surface 11 of the platform 10 (so as not to project from the floor surface 11), and the side edge is I was supposed to wear it on 12. Therefore, for example, when the vehicle 14 is not stopped in the station yard, an article (easy to roll) or the like dropped by the customer on the platform 10 is directed toward the side edge 12.
In the case of moving in the direction of arrow A in FIG. 9 and about to fall under the platform (on the track), it was impossible to prevent this suitably. That is, the conventional step member 16 has only a technical idea of narrowing the gap defined between the vehicle 14 and the platform 10, and prevents articles from falling below the platform, or There has been no technical idea of additionally providing a function of preventing an accident in which a disabled person in a wheelchair falls with the wheelchair.

On the other hand, in the above-described platform step device, the step is always the platform 10
It is stored in the accommodation position of No. 1 and operates only when the vehicle 14 stops in the station yard, and the step advances to the side of the vehicle 14. However, there is a problem that the equipment cost is high because the apparatus itself is expensive, and there is a problem that the platform 10 becomes narrow when the installation site of the apparatus is secured. Moreover, as described above, when the vehicle 14 is not parked inside the station, the step is stored in the accommodation position of the platform 10, so that articles are prevented from falling under the platform and persons with disabilities in a wheelchair are prevented from falling. It was impossible to do.

[0008]

The present invention has been proposed in order to suitably solve the above-mentioned problems. (1) Appropriate mounting on a platform, (2) Prevention of falling of articles, wheelchairs, etc. under the platform,
(3) An object of the present invention is to provide a step member for a platform, which can appropriately prevent damage to a vehicle body due to contact with a vehicle.

[0009]

In order to solve the above problems and to achieve the intended purpose, the step member of the platform according to the present invention is formed of an elastic material to a required length, and the length of the platform is lengthened by an appropriate attaching means. The main body is mounted along the side edge in the direction, and the upper surface of the main body is configured as a step surface projecting a required amount upward from the platform floor of the platform.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Next, a step member of a platform according to the present invention will be described below with reference to a preferred embodiment with reference to the accompanying drawings. In the description of the conventional technique, the same members and parts as those already shown in FIG. 9 will be designated by the same reference numerals.

FIG. 1 is a schematic perspective view showing a side edge of a platform mounted with a step member according to a preferred embodiment of the present invention in a broken state, and FIG. 2 is a step mounted on the side edge of the platform. FIG. 3 is a sectional front view of the member shown in FIG.
FIG. 4 is a sectional view taken along line IV-IV. FIG. 5 is an overall perspective view of the step member 20 of the embodiment.

The step member 20 of the embodiment is an extruded product formed from an elastic material such as chloroprene rubber (CR) based on a known extrusion molding technique, and the extruded product formed into a long length. Is formed by cutting into a desired length, and is configured by a cylindrical main body 22 having internal spaces 22a opened at both ends. The main body 22 has a substantially trapezoidal shape in cross section when cut in the lateral direction, as shown in FIG. 3, and the height dimension H is approximately twice the width dimension W. ing. Here, for convenience of explanation, the platform 1
The side adjacent to 0 (the right side in FIG. 3) is the rear side wall, the side adjacent to the vehicle 14 (the left side in FIG. 3) is the front side wall, and the upper side in FIG. 3 is the upper wall and the lower side is It will be the lower wall.

Since such a step member 20 is made of the above-mentioned elastic material and is made up of the main body 22 formed in the shape of a hollow prism, it has appropriate elasticity and flexibility. ing. Therefore, as shown in FIG.
When it is possible to flexibly deform in the direction of arrow B along the longitudinal direction, and when a pressing force in the direction of arrow C acts on the front side wall portion where the vehicle body receiving surface 28 described later is formed. In, by appropriately deforming the upper wall portion and the lower wall portion,
The front side wall can be elastically displaced toward the rear side (inside). However, even if a wheelchair with a handicapped person or a few adults are placed on a step surface 26, which will be described later, provided on the upper wall portion, the step surface 26 has such a rigidity that it is hardly deformed.

The chloroprene rubber has not only the above-mentioned rubber characteristics (flexibility and elasticity) but also well-known weather resistance, ozone resistance, heat aging resistance, oil resistance and resistance. It also has various properties such as excellent chemical resistance and flame retardancy, and is highly resistant to so-called external environments. Therefore, this chloroprene rubber
The step member 20 attached to the side edge 12 of the platform 10 that is easily exposed to direct sunlight, wind and rain, etc.
It is suitable as a main body material of. However, the elastic material used as the main body material of the step member 20 is not limited to this chloroprene rubber, and the main body 22 may be molded with another elastic material having the same level of characteristics. Good.

As described above, in the step member 20 of the embodiment formed in the above-mentioned rectangular tube shape, the rear side wall portion of the main body 22 having a horizontally long strip plate shape has the attaching means 4 described later.
0 is used as a fixed support portion 24 fixed along the side edge 12 of the platform 10, and the upper surface of the upper wall portion having a horizontally long strip plate shape in the main body 22 has a step surface 26 described later. Is configured as. This allows
By fixing the fixed support portion 24 to the side edge 12 of the platform 10 using the attachment means 40,
The step surface 26 is aligned with the boarding / alighting surface 11 of the platform 10 and extends forward from the boarding / alighting surface 11. Then, the step surface 26 is located between the side surface of the vehicle body of the vehicle 14 and the platform 10, so that the gap defined between the two 14 and 10 can be narrowed.

The step member 20 of the embodiment is shown in FIG.
As shown in FIG. 4, the step surface 26 is mounted on the side edge 12 of the platform 10 in a state of being projected upward from the boarding / alighting surface 11 of the platform 10 by a required amount. That is, the step surface 26
Is the side away from the side adjacent to the platform 10.
It is a flat surface that gradually inclines upward (to the side adjacent to the vehicle 14), and a required inclination angle R is given to the horizontal plane. As a result, the height of the side adjacent to the platform 10 is substantially the same as the height of the boarding / alighting floor 11, so that the distanced side is higher than the boarding / alighting floor 11 by the protrusion amount S. Here, the protrusion amount S is determined by the size of the tilt angle R and the width dimension W described above.
Is set to be in the range of 3 to 10 degrees, and is set to approximately 10 mm.

By thus forming the step surface 26 as a flat surface that gradually inclines upward toward the side away from the platform 10, the step surface 26 is on the platform 10 when the vehicle 14 is not stopped in the station yard, for example. The article dropped by the customer (easy to roll) is in the direction of the side edge 12 (see FIG. 3).
When it moves in the direction of the arrow A), it can be depressed by appropriately climbing on the step surface 26 and it can return to the direction of the platform 10 to prevent the article from falling below the platform. It is like this. Further, even when the wheelchair on which the disabled person rides moves toward the side edge 12, the wheel gets on the step surface 26 to stop the wheelchair, and the wheel disengages from the platform 10. It is also possible to prevent an accident in which a disabled person in the wheelchair falls under the platform.

The outer surface (side surface) of the front side wall portion of the main body 22 faces the front side of the fixed support portion 24 and serves as a vehicle body receiving surface 28 for the vehicle body side surface of the vehicle 14. That is, the vehicle body receiving surface 28 is vertically supported by the upper wall portion and the lower wall portion and extends at an appropriate interval with respect to the fixed support portion 24. As a result, when the vehicle 14 stopped at the station yard contacts the vehicle body receiving surface 28,
The upper wall portion and the lower wall portion elastically support the front side wall portion so that no load is applied to the side surface of the vehicle body of the vehicle 14. Therefore, even if the vehicle 14 comes into contact with the vehicle body receiving surface 28, it is possible to preferably prevent the generation of unpleasant contact sound, and also preferably prevent the side surface of the vehicle body of the vehicle 14 from being scratched or peeled off. You can

The opening width of the gap defined between the vehicle 14 stopped at the station and the platform 10 varies depending on the radius of curvature of the curve of the platform 10, the total length of the vehicle 14, and the like. For this reason, it is desirable that the step member 20 of the embodiment is standardized in a plurality of sizes having different width dimensions W. Specifically, the main body 2
The total length L and the height H of 2 are common, the total length L is about 2000 to 2500 mm, and the height H is 15
It is set to about 0 to 170 mm. Under this width dimension W
If, for example, a range of 50 to 200 mm is set for every 10 mm, a total of 16 types of main bodies 22 having different widths for every 10 mm can be standardized, so that the optimum width according to the opening width of the gap can be obtained. The width dimension can be adopted without pre-processing.

The mounting means 40 is used for the platform 10.
A plurality of anchor bolts 42 (five in the embodiment) fixed by being driven at predetermined intervals with respect to the side edge 12 of each of the anchor bolts 42 and each of the anchor bolts 42 housed in the internal space 22a of the main body 22. It is composed of a flat plate 44 that engages with each other, and a nut 46 that is fastened to each anchor bolt 42. As a result, the fixed support portion 24 of the main body 22 is
A bolt insertion hole 30 is formed to allow the insertion of each anchor bolt 42, while the vehicle body receiving surface 28 is provided with five nut insertion holes 32 at positions opposed to the bolt insertion holes 30. It is provided at intervals. Each nut insertion hole 32 is used when fastening the nut 46 to the anchor bolt 42, and is a fastening tool for the nut 46.
The opening size is set to allow insertion (not shown). Further, the flat plate 44 has an overall length slightly shorter than the overall length L of the main body 22 and can be flexibly deformed along the longitudinal direction to allow the insertion of the anchor bolts 42. Bolt insertion holes 48 are provided.

The side edge 12 of the platform 10 is
If there is a step on the side edge 12, as shown in FIG.
The step member 20 may be mounted after being set to.

[0024]

Operation of the embodiment The step member 20 of this embodiment is mainly composed of a cylindrical main body 22 formed by cutting an extrusion-molded product into a required length, and can be manufactured at a low cost. Supplied at the price. Moreover, based on the opening width of the gap defined between the vehicle 14 and the side edge 12 of the platform 10, if the body 22 having the optimum width dimension W is selected from those standardized as described above. For this reason, no pre-processing or the like is required when attaching to the side edge 12 of the platform 10.

The selected step member 20 is attached to the lateral side edge 12 in the longitudinal direction of the platform 10 by using the attaching means 40. Specifically, first, the anchor bolts 42 constituting the mounting means 40 are driven into the side edge 12 of the platform 10 at required intervals.
Next, the main body 22 accommodating the flat plate 44 in the internal space 22a is attached to the side edge 12 of the platform 10.

The attachment of the step member 20 to the side edge 12 of the is completed.

In the step member 20 of the embodiment, the flat plate 44 is appropriately deformed as the nuts 46 are tightened, so that the fixed support portion 24 is appropriately deformed and the side edge 12 of the platform 10 is deformed. And come into close contact. That is, even if the side edge 12 of the platform 10 is provided with a required radius of curvature, each nut 4
With the tightening work of 6, the main body 22 follows the shape along the side edge 12, and there is almost no gap between the step member 20 and the platform 10.
(FIGS. 3 and 4). Therefore, when the step member 20 is mounted, the anchor bolt 42 is simply driven into the lateral edge 12 of the platform 10, so that no major remodeling work of the platform 10 is required, and the step member 20 is mounted as described above. Since the pre-processing of 20 is not necessary, the construction cost can be minimized and the mounting can be made appropriate and simple.

In the platform 10 equipped with the step member 20 of the embodiment, as shown in FIGS. 3 and 4, the distance between the vehicle body side surface of the vehicle 14 stopped in the station and the vehicle body receiving surface 28 of the main body 22 is 3 mm. It is set to about 4 cm. As a result, the gap between the vehicle 14 and the platform 10 is small, so that no inconvenience is given to passengers when getting on or off the vehicle 14, and especially for infants,
It is possible to prevent a visually impaired person, a drunk person, etc. from getting caught and an injury accident due to this. Further, even if the passenger gets in and out by mistake while dropping a carrying item such as a bag, the step surface 26 can catch the dropping, so that the carrying item can be appropriately prevented from falling below the platform. Furthermore,
Even a physically handicapped person who uses a wheelchair can properly get on and off the vehicle 14 because the wheels of the wheelchair are guided and supported by the step surface 26 when getting on and off.

Further, when the vehicle 14 parked inside the station comes into contact with the vehicle body receiving surface 28, the main body 22 made of the elastic material is elastically deformed to an appropriate degree. The vehicle 14 can be appropriately prevented from being generated.
It is also possible to prevent scratches and paint peeling from occurring on the vehicle body side surface. In particular, since the anchor bolt 42 and the nut 46 of the mounting means 40 are housed in the internal space 22a and do not project outward from the vehicle body receiving surface 28 of the main body 22, the vehicle 1
Even if the vehicle body side surface of 4 touches the vehicle body receiving surface 28 and the body 22 is appropriately deformed, the anchor bolt 42 and the nut 46
Does not contact the vehicle 14.

In the platform 10 equipped with the step member 20 of the embodiment, the step surface 26 of the step member 20 has the step-on / fall surface 1 of the platform 10.
It is in an upwardly inclined state in which the required amount is projected upward from 1. Therefore, even if the article dropped by the customer on the platform 10 moves in the direction of the side edge 12 (direction of arrow A in FIG. 3) when the vehicle 14 is not stopped in the station, the step surface 26 Weakened when riding on
Since it comes to stop and returns, it is possible to suitably prevent the article from falling below the platform. Further, even if the wheelchair on which the disabled person rides moves toward the side edge 12, the wheelchair will stop when the wheel gets on the step surface 26, and the disabled person on the wheelchair will be at home. Accidents that fall down can be prevented in advance.

In the above embodiment, the step surface 26 has a flat surface that gradually inclines upward, but other shapes may be used. For example, the step surface 26 has an upward concave curved surface shape such that the inclination gradually increases from the side adjacent to the platform 10 (the side adjacent to the vehicle 14), or the convex portion with the central portion most protruding. It may have a curved shape or the like.

In FIG. 6, a plurality of protrusions 34 are provided on the step surface 26 at appropriate intervals so that the step surface 26 can be formed.
Is uneven. In this way, the step surface 26
If the shape is uneven, it is possible to prevent slipping in the event of rain or snow, and it is possible to further enhance the effect of depressing the article or the like that has climbed onto the step surface 26.

Further, in FIG. 7, a sticker-like display body 36 is attached to the step surface 26. This display 3
Reference numeral 6 is, for example, a color sticker having a color tone / color that can draw attention, a reflective sticker that reflects when the headlight light of the vehicle 14 is irradiated, and the like. If such a display body 36 is attached to the step surface 26, the platform 1
This is effective in preventing a fall accident while walking on the ground, a collision accident with the vehicle 14 entering the station yard, a foot stepping accident when getting on and off, and the like.

A main body 22 which constitutes the step member 20
Is not limited to the cylindrical shape shown in FIGS.
For example, as shown in FIG. 8, a laterally long slit may be provided in the upper and lower central portions of the vehicle body receiving surface 28.
Even if the main body 22 has such a form, the fixed support portion 24,
The step surface 26 protruding upward from the boarding / alighting floor surface 11 of the platform 10, the vehicle body receiving surface 28, and the like can be preferably formed, and can have the same function as the step member 20 of the above-described embodiment.

The inclination angle R of the step surface 26 is set in the range of 3 to 10 degrees as described above, assuming that the width W of the main body 22 is set in the range (50 to 200 mm). Is desirable. That is, the inclination angle R
If the angle is set to 3 degrees or less, the amount S of protrusion of the platform 10 from the boarding / alighting floor surface 11 may be too small, and it may not be possible to appropriately prevent falling of articles below the platform or falling of a wheelchair. On the other hand, when the inclination angle R is set to 10 degrees or more, the protrusion amount S of the platform 10 from the boarding / alighting floor surface 11 may become too large, which may cause inconvenience such as getting in the soles of passengers. There is.

[0035]

As described above, the step member of the platform according to the present invention is mounted while being deformed so as to be in close contact with the lateral side edge in the longitudinal direction of the platform. There is an advantage that simplification can be achieved. Moreover, since the step member is easily attached to the side edge of the platform by the mounting means, no major remodeling work of the platform is required, and no pre-processing of the step member is required. It has extremely beneficial effects that can be minimized. And the step surface of the step member is projected upward from the platform boarding / alighting surface by a required amount, so that articles falling on the platform boarding / alighting surface can be prevented from falling below the platform, or the user can get on a wheelchair. It also has the effect of preventing a person with a disability from falling below the platform.
Further, even if a vehicle stopped in the station yard comes into contact with the step member, it is possible to suitably prevent the generation of unpleasant contact noise and also prevent the occurrence of scratches or paint peeling on the vehicle body side surface of the vehicle. obtain.
