Definitions

  • the present invention relates, in general, to safety gap fillers which are attached to track-side edges of platforms of railway stations, including subway stations, to reduce gaps between the platforms and trains and, more particularly, to a safety gap filler for railway platforms which is constructed such that several support bars, which are provided at positions spaced apart from each other in a horizontal direction at regular intervals, are inclined at a predetermined angle in the direction in which a train travels, thus effectively preventing the feet of passengers or the wheel of a cart or the like from becoming caught between the support bars when the passengers get on or off the train, and reducing frictional force with respect to the train.
  • platforms are provided around the tracks such that passengers can get on or off the trains.
  • the platforms are typically constructed at predetermined heights corresponding to the bottoms of doors of the trains to ensure convenience when passengers get on or off the trains.
  • a gap is un-avoidably defined between each door and the edge of the platform.
  • the gap therebetween is further increased. Due to this gap, there is the possibility of a safety hazard, for example, the foot of a passenger (particularly, a child) becoming caught in the gap when getting on or off the train.
  • the platform be constructed such that the gap between the train and the edge of the platform be as narrow as possible, but, in consideration of various factors including the characteristics of the trains, a gap having a predetermined width unavoidably exists therebetween.
  • a method in which a device called a “safety gap filler” is attached to the edge of the platform has been proposed.
  • a fastening plate which has a band shape, is fastened to the edge of the platform which is adjacent to the tracks.
  • gap prevention members which are made of soft material, are perpendicularly coupled to one surface of the fastening plate at positions spaced apart from each other at regular intervals, thus forming an approximate fork shape.
  • the conventional safety gap fillers have the following problems.
  • the length to which the gap prevention members 3 protrude from the fastening plate 2 must be equal to or slightly greater than the gap therebetween.
  • the gap prevention members 3 are perpendicular to the train T, when the train T approaches or leaves the platform, the ends of the gap prevention members 3 are bent a lot when they come into sliding contact with the train T even though the backward displacement D, within which the ends of the gap prevention members 3 are moved in the direction away from the train, is relatively small. Therefore, the frictional force between the train and the safety gap filler is greatly increased.
  • the conventional safety gap filler 1 is constructed such that ends of the gap prevention members 3 are spaced apart from the train by a predetermined distance, as shown in FIG. 2 . That is, in the case of a person such as a child, having small feet, there still is the possibility of a safety hazard in which the foot may become caught in the gap.
  • the wheels W of a carrier such as a cart may undesirably enter the space between the gap prevention members 3 when getting on or off the train T, thus causing a safety hazard.
  • an object of the present invention is to provide a safety gap filler for railway platforms which can satisfactorily remove the gap between a train and an edge of the platform which is adjacent to tracks and can prevent the size of gaps between support bars from being increased by the weight of passengers, thus effectively preventing the feet of passengers or the wheel of a cart or the like from becoming caught between the support bars when the passengers get on or off the train.
  • Another object of the present invention is to provide a safety gap filler for railway platforms which markedly reduces the frictional force induced by coming into sliding contact with the train when the train approaches or leaves the platform.
  • the present invention provides a safety gap filler provided on an edge of a railway platform that is adjacent to tracks to reduce a gap between the platform and a train
  • the safety gap filler including: a fastening base body attached to the edge of the platform that is adjacent to the tracks in a direction parallel to the tracks, the fastening base body having a band shape, a width of which is small, and a height of which is large; and a plurality of support bars protruding predetermined lengths from a surface of the fastening base body towards the tracks at positions spaced apart from each other at regular intervals, each of the support bars having a plate shape, which is small in width and large in height, and being inclined at a predetermined angle with respect to the fastening base body in a direction in which the train travels, so that the support bars are elastically brought into sliding contact with a sidewall of the train.
  • the fastening base body and the support bars may be manufactured through separate processes and assembled with each other into a single body, wherein the fastening base body may be made of a hard material such as synthetic resin and has in one surface thereof a plurality of dovetail slots, each of which is closed at a lower end thereof, and each of the support bars may be made of a soft material such as rubber such that the support bar bends when contacting the train, with a first dovetail provided on a proximal end of each of the support bars, the first dovetail being fitted into the corresponding dovetail slot of the fastening base body.
  • the fastening base body may be made of a hard material such as synthetic resin and has in one surface thereof a plurality of dovetail slots, each of which is closed at a lower end thereof
  • each of the support bars may be made of a soft material such as rubber such that the support bar bends when contacting the train, with a first dovetail provided on a proximal end of each of the support bars, the first
  • a cross-section of each of the support bars may have a tapered shape which is reduced in width from the top thereof to the bottom. Therefore, the contact area between the foot of the passenger and the support bar is increased as much as possible, and foreign objects, which are held between the support bars, can be easily removed therefrom in a downward direction.
  • the safety gap filler may further include a sliding shoe provided on a distal end of each of the support bars, the sliding shoe having superior abrasion resistance and superior impact resistance.
  • a gap is reliably prevented from being defined between the platform and the door of a train. Furthermore, because support bars are angled at appropriate angles with respect to a fastening base body, that is, in a direction crossing the direction in which passengers get on or off the train, the distances between the support bars are prevented from being increased by the weight of the passengers. Therefore, when the passengers get on or off the train, the foot of a passenger or the wheel of a cart or the like is effectively prevented from becoming caught between the support bars.
  • the support bars are inclined in the direction in which the train travels, when the support bars are brought into contact with the train, they are easily bent. As well, when the train approaches or leaves the platform, because the support bars are in sliding contact with the train, frictional noise is markedly reduced.
  • the present invention has superior effects in that the reliability of the station and the stability when passengers get on or off the train are greatly enhanced.
  • FIGS. 1 through 3 are plan views illustrating problems with a conventional safety gap filler for railway platforms
  • FIG. 4 is a perspective view of a safety gap filler for a railway platform, according to a first embodiment of the present invention
  • FIG. 5 is a plan view showing the safety gap filler of FIG. 4 attached to the edge of the station platform adjacent to a track;
  • FIG. 6 is a sectional view taken along the line IV-IV of FIG. 5 ;
  • FIG. 7 is a sectional view taken along the line V-V of FIG. 5 ;
  • FIG. 8 is a partial plan view of the operation of the safety gap filler according to the present invention.
  • FIG. 9 is a partial plan view showing another type of support bars of the safety gap filler according to the present invention.
  • FIG. 10 is a partial plan view of a safety gap filler for a railway platform, according to a second embodiment of the present invention.
  • FIG. 11 is a side view seen along the arrow IX of FIG. 10 ;
  • FIG. 12 is a sectional view showing the installation of a safety gap filler for a railway platform, according to a third embodiment of the present invention.
  • FIG. 13 is a plan view seen along the arrow XI of FIG. 12 ;
  • FIG. 14 is a partially exploded perspective view showing a safety gap filler for a railway platform, according to a fourth embodiment of the present invention.
  • FIG. 15 is a plan view showing the assembled safety gap filler of FIG. 14 ;
  • FIGS. 17 and 18 are sectional views showing modifications of the safety gap filler according to the fourth embodiment of the present invention.
  • the fastening base body 11 and the support bars 12 are made of soft material, for example, rubber or urethane, and are integrally formed into a single body.
  • the fastening base body 11 has the shape of a narrow and tall band.
  • the fastening base body 11 is fastened to the edge of the platform F that is adjacent to the tracks, for example, using screws 13 .
  • the support bars 12 are angled with respect to the fastening base body 11 at predetermined angles ⁇ in the direction in which the train T travels. If the inclination angle ⁇ is too small, frictional force is reduced, but the length of each support bar 12 must be increased. If the inclination angle ⁇ is increased close to 90°, the length of the support bar 12 is reduced, but, because the bending displacement S, by which the end of the support bar 12 is bent, greatly increases with respect to the backward displacement D, by which the end of the support bar 12 is moved in a direction away from the train, the frictional force is increased.
  • the inclination angle ⁇ of the support bar 12 ranges from 30° to 60°.
  • each support bar 12 has a tapered cross-section in which the width thereof is reduced from the top to the bottom. Thanks to this structure, the contact area between the foot of the passenger and the support bar 12 is increased as much as possible such that a passenger can stably step on the step board, and foreign objects, which are held between the support bars 12 , can be easily removed therefrom in a downward direction.
  • the support bars 12 which protrude towards the tracks to fill the gap between the platform F and the train T, are inclined at predetermined angles in the direction in which the train T travels, passengers can very safely get on or off the train, and carriers such as carts can also easily and safely get on or off the train.
  • the safety gap filler 10 of the present invention because the support bars 12 are inclined in the direction in which the train T travels, as shown in FIG. 8 , at least one support bar 12 always supports the wheels W of a cart when it gets on or off the train. Therefore, there is little possibility of the wheel W becoming caught between adjacent support bars 12 . As such, the present invention makes it possible for passengers to safely get on or off the train T.
  • a sliding shoe 16 which is made of hard material, such as FRP or plastic, having superior abrasion resistance and superior impact resistance, is further provided on the distal end of each support bar 12 .
  • the fastening base body 21 is made of hard synthetic resin and has in one surface thereof a plurality of dovetail slots 23 , each of which is closed at the lower end thereof.
  • Each support bar 22 is made of soft material such as rubber such that it bends when it contacts the train T.
  • each support bar 22 has on a proximal end thereof a dovetail 24 , which is fitted into the corresponding dovetail slot 23 of the fastening base body 21 .
  • the fourth embodiment has an advantage in that, in the case where some support bars 22 are worn, only the worn support bars 22 need be replaced with new ones.
  • the surface of the platform F is not level with the bottom of a door of the train T. That is, as shown in FIGS. 17 and 18 , the bottom of a door of the train T is generally higher or lower than the surface of the platform F.
  • the safety gap filler according to the fifth embodiment having the above-mentioned construction has an effect in that the durability of the support bar 22 is increased, thus extending the lifetime of the safety gap filler 20 .
  • FIGS. 20 and 21 schematically illustrate a safety gap filler 20 for a railway platform, according to a sixth embodiment of the present invention.
  • a gap is reliably prevented from being defined between the platform and a door of a train. Furthermore, because support bars are angled at appropriate angles with respect to a fastening base body, that is, in a direction crossing the direction in which passengers get on or off the train, gaps between the support bars are prevented from being widened by the weight of the passengers. Therefore, when the passengers get on or off the train, the foot of a passenger or the wheel of a cart or the like is effectively prevented from becoming caught between the support bars.
  • the support bars are inclined in the direction in which the train travels, when the support bars are brought into contact with the train, they are easily bent. As well, when the train approaches or leaves the platform, because the support bars are in sliding contact with the train, frictional noise is markedly reduced.
