Description

[0001] The present invention relates to a safety step device for a train,

The present invention relates to a safety footrest installed to prevent a passenger from falling out at a distance between pedestrians between a train car and a platform on a train platform. Specifically, the safety footrest is unfolded after the train car enters the platform, It is not necessary to block out the platform when installing the platform, so that the platform can be installed not only on the new platform but also on the existing platform, and the load of the passenger can be firmly established The present invention relates to a folding type safety footrest for preventing falling off of a train platform, which can be safely supported and has a structure in which the length in the lateral direction (direction perpendicular to the train running direction) is automatically adjusted.

There is a predetermined gap ('gap') between the train car and the platform of the subway or train for smooth and safe running of the train car. Therefore, when a train vehicle stops at a platform and a passenger gets on and off, an accident often occurs in which the foot falls or falls due to a gap existing between the entrance door and the platform of the train vehicle. In order to prevent this, it is necessary to install a safety footrest on the platform in order to recognize a train vehicle stopping at the platform, thereby blocking a gap between the entrance door of the train vehicle and the platform.

As disclosed in Korean Patent No. 10-0279326, the safety footrest according to the prior art is hidden in the platform, and when the train vehicle stops at the platform, the safety footrest advances horizontally toward the entrance of the train car, It has a barrier structure. However, in the case of the safety footrest according to the related art, since the safety footrest moves horizontally, the load from the passengers can not but be supported by the "cantilever structure" in a state in which the safety footrest is spread so as to block the gap, Durability and safety are not properly secured.

Also, in this conventional technology, when the train vehicle does not enter, the safety footrest is horizontally retreated in the direction of the landing, and is concealed. To this end, a space in which the safety footrest is to be inserted must be secured by block-out. That is, in the prior art, a concave space due to block-out must be formed in the landing area. However, the presence of the concave space in the landing platform results in weakening the rigidity of the landing platform itself. Further, in order to install the safety footrest of the prior art on the existing platform, it is necessary to separately perform an additional block-out operation for the platform, so that the safety footrest of the prior art is not suitable for the existing platform.

Due to mechanical limitations such as maximum minimum wheel distance, maximum wheel minimum thickness, maximum flange minimum thickness, rail maximum and minimum rail maximum and minimum, maximum and minimum rail misalignment, and operating clearance, A tolerance of about 0 to 30 mm is inevitably generated, and this tolerance differs for each train vehicle that stops at the platform. Therefore, even if a safety footrest is provided according to the related art, there is always a problem that an elderly person or a blind cane can be caught in a gap existing due to such a tolerance.

Also, according to the curve of the platform, the interval between the railway car and the platform is inevitably different according to the angle of bending of the platform.

Particularly, in the case of the safety footrest according to the related art, when the safety footrest protrudes due to the failure of the safety footrest, the side of the train car must collide with the safety footrest when the train car enters the platform If the train car collides with the safety footrest, damage to the train car and the safety footplate occurs, and also the obstacle and delay of the train operation due to the train collision occur. Therefore, even if a train car enters a state in which the safety footrest protrudes from a fault, a safety footrest with a structure in which the safety footrest and the side of the train car do not collide with each other is urgently required.

Korean Patent Registration No. 10-0279326 (published on January 15, 2001).

SUMMARY OF THE INVENTION The present invention has been developed in order to overcome the problems and limitations of the prior art as described above, and it is an object of the present invention to provide a safety footrest which interrupts a gap between an entrance door and a platform of a train car when the train car stops at a platform, It is possible to easily install the platform without block-out while ensuring stability and durability better than the safety platform, and the lateral length of the safety platform is automatically adjusted so that the safety platform is projected laterally due to failure of the platform The object of the present invention is to provide a safety footrest which can be easily applied to a conventional platform as well as a new platform in order to prevent a train vehicle entering a platform from colliding with a safety platform.

According to an aspect of the present invention, there is provided a load supporting structure comprising: a load supporting plate hinged to a front of a landing so as to be rotatable and having a plurality of longitudinally arranged spacing; A horizontal protection plate fixed to the upper portion of the load supporting plate at the front side of the landing to protect the load supporting plates in the folded state; An interval closing member rotatably provided at an upper portion of a transverse outer edge of the load supporting plate to contact the train vehicle; A horizontal protection plate fixed to the upper portion of the load supporting plate at a front surface of the landing pad so as to form a continuous plane with the upper surface of the landing pad; And a rotary cover plate rotatably hinged to the horizontal protection plate so as to be changed from a horizontal position to a vertical position; In a state in which passengers can not ascend and descend to the train vehicle, the load supporting plate is in a folded state and the rotating cover plate is in a vertical state; When a situation in which passengers are to be lifted or lowered on a train car comes, a plurality of load support plates simultaneously rotate together and become a deployed state in which the load support plates are vertically arranged to be orthogonal to the front face of the landing platform, The lower end of the rotating lid plate is supported by a vertically arranged load supporting plate and the gap closing member contacts the side surface of the train car while closing the gap between the train vehicle and the platform, Is prevented from falling into or falling down from the floor.

In the folding type safety footrest according to the present invention, a driving wire is connected to a first outermost load supporting plate located at one end in the longitudinal direction among a plurality of load supporting plates, and a driving motor for pulling or loosening the driving wire is connected to the One end of the tension spring is connected to the second outermost load supporting plate located at the other end in the longitudinal direction adjacent to the outer load supporting plate and the other end of the tension spring is coupled to the front of the loading station, The first outermost load supporting plate is rotated and all of the plurality of load supporting plates including the first outermost load supporting plate are in a deployed state in which they are all perpendicular to the landing front face, Is released and released from the state in which the driving wire is pulled, the tension from the tension spring The second outermost load supporting plate automatically rotates in the direction of the front of the landing, and all of the load supporting plates simultaneously rotate in the direction of the front of the landing to be in a folded state. In particular, it may have a configuration in which a load supporting plate, an interval closing member, a driving motor, a driving wire, and a tension spring are all present in a folded state in a region covered with the horizontal protection plate.

In addition, in the safety footrest according to the present invention, when the load-bearing support plate is rotated and the rotary cover plate is pushed to bring the rotary cover plate into a horizontal position, the load support plate maintains a state in which the upper surface thereof is in close contact with the lower face of the rotary cover plate, A sliding member may be further provided on the upper portion of the load supporting plate so as to be brought into close contact with the lower surface of the rotating lid plate in a low friction state so that the load supporting plate can rotate in a low friction state. In this case, the sliding member is composed of a body coupled to the load supporting plate and a rolling bearing provided at the upper end of the body, so that the rolling bearing rolls in a state of being closely attached to the lower surface of the rotating lid plate, And may be configured to rotate in close contact with the cover plate in a low friction state.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and operation are not limited thereby.

In the description of the present invention, "longitudinal direction " means the direction in which the train travels, and" lateral direction " means the direction from the landing to the train vehicle, i.e., the direction perpendicular to the longitudinal direction.

Fig. 3 is a schematic exploded perspective view showing the state of Fig. 1 in which the rotating lid plate 2 and the gap closing member 5 are both separated for the sake of convenience in order to show the structure of the load supporting plate 1. Fig. 4 A schematic enlarged view of the circle A portion of Fig. 3 showing the sliding member 7 in detail is shown. 5 is a schematic exploded view showing the state of Fig. 1 in which only the rotating lid plate 2 is separated for convenience, in order to show a form in which the interval closing member 5 is rotatably engaged with the transverse end of the load supporting plate 1. [ A perspective view is shown, and in Fig. 6 a schematic enlarged view of the circle E portion of Fig. 5 is shown. FIG. 7 shows a schematic longitudinal cross-sectional view along line B-B of FIG. 1, and FIG. 8 shows a schematic plan view of the state shown in FIG.

The folding type safety footrest 100 according to the present invention is installed on a front surface of the landing platform 200, that is, a surface facing a train car, at a position where a door of a train vehicle exists when the train vehicle stops at the platform 200, Specifically, it has the following configuration.

The folding type safety footrest 100 according to the present invention is provided with a load supporting plate 1 vertically disposed on the front face of the landing platform. The lateral inner edge of the load supporting plate 1 is fixed to the front of the landing platform 200, And is hinged to be rotatable in a direction. That is, the load supporting plate 1 is installed so as to be able to rotate in the longitudinal direction about the rotational axis located at the vertical inner edge of the transverse direction, which is in close contact with the front surface of the landing platform 200. A plurality of load supporting plates 1 are provided at intervals in the longitudinal direction, and the plurality of load supporting plates 1 are connected to each other by neighboring load supporting plates 1 by link members 11 arranged in the longitudinal direction .

Accordingly, when one load supporting plate 1 having a rotational driving force is rotated in the longitudinal direction, the other load supporting plates are simultaneously rotated together in the longitudinal direction. That is, when one load supporting plate 1 is in the folded state and then rotated in the unfolded state of FIG. 1, the other load supporting plates are simultaneously and simultaneously folded together and then rotated to the unfolded state of FIG. It goes without saying that the same is true in the case of being in the unfolded state shown in Fig. 1 and then rotating in the folded state.

In the embodiment illustrated in the drawings, the drive wire 91, the drive motor 9, and the tension spring 92 are used. In this embodiment, According to the configuration, the folded state and the unfolded state of the load support plate 1 can be easily accomplished, and the facilities for the load support plate 1 can be simplified, thereby reducing the cost. Specifically, in the embodiment shown in the drawings, the first outermost load supporting plate 1a located at one end in the longitudinal direction among the plurality of load supporting plates 1 corresponds to the load supporting plate having the above rotational driving force, A driving wire 91 is connected to the outermost load supporting plate 1a and a driving motor 9 for pulling or loosening the driving wire 91 is installed on the front of the platform in the longitudinal direction adjacent to the outermost load supporting plate 1a . On the other hand, one end of a tension spring 92 is connected to the second outermost load supporting plate 1b located at the other longitudinal end in the longitudinal direction, and the other end of the tension spring 92 is coupled to the front of the landing pad. That is, a tensile spring 92 is provided between the second outermost load supporting plate 1b and the landing platform so that a tensile force is always applied to pull the second outermost load supporting plate 1b toward the front of the landing platform.

In this configuration, when the drive motor 9 is actuated to pull the drive wire 91, the first outermost load supporting plate 1a is rotated, and as a result, the first outermost load The support plate 1a is in a state of being orthogonal to the front of the landing gear. As described above, since all of the plurality of load supporting plates 1 including the first outermost load supporting plate 1a are connected to the link member 11 between the adjacent load supporting plates 1, The first outermost load supporting plate 1a and the second outermost load supporting plate 1b are rotated simultaneously when the first and second load supporting plates 1a and 1b are rotated so as to be in a state of being orthogonal to the platform front face, All of the plurality of load supporting plates 1 including the load supporting plate 1 are perpendicular to the landing front face. That is, the load supporting plate 1 is in the " unfolded state (unfolded state) ".

On the other hand, since the tension spring 92 is provided between the second outermost load supporting plate 1b and the landing platform, the driving wire 91 is pulled as described above, so that the second outermost load supporting plate 1b, A strong tensile force is applied to the second outermost load supporting plate 1b to pull the second outermost load supporting plate 1b in the direction of the front of the landing by the tension spring 92 . In this state, when the drive motor 9 is released from the state in which the drive wire 91 is pulled and released, the second outermost load supporting plate 1b is automatically lifted by the tensile force from the tension spring 92 So that all the other load supporting plates 1 that are engaged by the link member 11 are simultaneously and simultaneously rotated in the direction of the landing surface to be folded as described later. That is, the load supporting plate 1 is in the "folded state"

In the present invention, an interval closing member 5 is rotatably provided on the upper side of the transversely outer edge of the load supporting plate 1. The gap closing member 5 extends in the longitudinal direction and has a width in the transverse direction and the upper surface is a flat rod-like member hinged to the lateral outer edge of the load supporting plate 1. [ 6, the hinge member 15 is vertically provided on the lateral outer edge of the load supporting plate 1, and the hinge member 15 can be fitted on the transverse inner side surface of the interval closing member 5 The lateral inner surface of the gap closing member 5 can be rotatably hinged to the lateral outer edge of the load supporting plate 1. [ At this time, when viewed in the vertical direction, the gap closing member 5 is located on the upper portion of the load supporting plate 1. [ Since the gap closing member 5 is a member elongated in the longitudinal direction, it is provided in such a manner that one gap closing member 5 is simultaneously coupled to the plurality of load supporting plates 1. [ When the load supporting plate 1 is in the unfolded state as described later, the gap closing member 5 is brought into close contact with the side surface of the train car so that no gap is formed between the rotation cover plate 2 and the side surface of the train car So that it is possible to prevent the occurrence of an accident in which a passenger's cane or shoe heel is caught in the gap. As described later, the spacing member 5 may be in close contact with the transverse side of the train vehicle. In order to prevent damage to the train vehicle, the spacing member 5 is preferably made of a soft material such as rubber or synthetic resin.

The folding type safety footrest 100 of the present invention is provided with a horizontal protection plate 3 fixed to the front face of the landing platform to protect the load supporting plates 1 in a folded state and to install the rotation lid plate 2. The horizontal protection plate 3 may be constituted by a plate member having a continuous plane with the upper surface of the platform and having a width in the lateral direction and having a longitudinal length longer than the width of the door of the train vehicle. The horizontal protection plate 3 has a longitudinal length capable of covering at least the upper portion of both the load supporting plate 1 and the gap closing member 5 which are at least in the fully folded state and in addition the driving motor 9 and the tension spring It is more preferable to have a sufficient longitudinal length so as to cover all the upper portions of the upper and lower portions 92 and 92. In particular, it is preferable that the horizontal width of the horizontal protection plate 3 is equal to or greater than the width of the upper portion of both the load supporting plate 1 and the gap closing member 5 in the fully folded state. The load supporting plate 1, the drive motor 9, the drive wire 91 and the tension spring 92 are all present in the folded state in the area covered by the horizontal protection plate 3, It is safely protected. If necessary, the horizontal protection plate 3 may further include a vertical protection plate perpendicular to the horizontal protection plate 3 at the longitudinal end thereof. When the vertical protection plate is additionally provided, it is possible to effectively prevent the horizontal protection plate 3 from being bent downward when the load of the passengers is applied to the horizontal protection plate 3.

The rotary cover plate 2 is rotatably hinged to the lateral outer edge of the horizontal protection plate 3. The rotary cover plate 2 is composed of a plate member having a transverse width and elongated in the longitudinal direction. The transverse width of the rotary cover plate 2 is determined by the width of the load support plate 1 as shown in Figs. 1 and 2, Is so large as to be able to cover the upper portion of the load supporting plate 1 when the rotating lid plate 2 is in the "fully extended state ". And the longitudinal length of the rotating lid plate 2 may correspond to the longitudinal length of the horizontal lid 3. The rotary hinge shaft for allowing the rotary lid plate 2 to rotate is formed to extend longitudinally in the longitudinal direction at the lateral outer edge of the horizontal protection plate 3. [

As described above, since the rotation lid plate 2 is rotatably engaged with the lateral outer edge of the horizontal protection plate 3, when the load support plate 1 is in the "fully collapsed state" Are arranged in one direction. When the load supporting plate 1 is changed from the fully folded state to the "unfolded state ", the load supporting plate 1 pushes the rotating lid plate 2 upward and lifts the rotating lid plate 2, 2, the lower surface thereof is supported by the load supporting plate 1, and is horizontally continuous with the horizontal protection plate 3 in a horizontal state.

In this way, when the load supporting plate 1 is changed from the "folded state" to the "unfolded state" and spreads beyond the width of the horizontal protection plate 3 in the plan view, The load supporting plate 1 is rotated while supporting the rotating lid plate 2 until the load supporting plate 1 is completely opened. In this way, the load supporting plate 1 is rotated until the upper part of the load supporting plate 1 is brought into a completely unfolded state while maintaining a state of being in close contact with the lower surface of the rotating lid plate 2. In order to smoothly rotate the load supporting plate 1 On the upper part of the load supporting plate 1, a sliding member 7 may be further provided. The sliding member 7 is engaged with the load supporting plate 1 and the upper end of the sliding member 7 is brought into close contact with the lower surface of the rotating lid plate 2. The upper end of the sliding member 7 is engaged with the rotation lid plate 2 when the load supporting plate 1 rotates. So that the friction with respect to the base 2 can be minimized. For example, the sliding member 7 may be configured such that the upper end of the sliding member 7 is constituted by a low friction member called so-called Teflon, or is covered with a film of such a low friction member.

4, the sliding member 7 is composed of a body 71 coupled to the load supporting plate 1 and a rolling bearing 72 provided at the upper end of the body 71, The rolling bearing 72 is allowed to roll in a state of being in close contact with the lower surface of the rotating lid plate 2 so that the load supporting plate 1 can rotate smoothly in a state of minimum friction with the rotating lid plate 2. The sliding members 7 may be provided on all the load supporting plates 1, but may be provided on only some of the load supporting plates 1.

Hereinafter, the operation of the folding type safety footrest 100 according to the present invention having such a configuration will be described with reference to FIGS. 9 to 16. FIG.

FIGS. 9 and 10 are perspective views schematically showing a folding safety footrest 100 according to the present invention in a completely folded state (fully folded state), and FIGS. 11 and 12 show a perspective view FIG. 13 is a schematic perspective view showing a direction in which the rotary cover plate 2 is removed and removed in order to show the configuration of the load support plate 1 in the folded state in detail, Lt; RTI ID = 0.0 > planar < / RTI >

In the state where the train vehicle does not enter the platform or the passenger can not descend to the train vehicle even though the train vehicle has entered the platform, the load-bearing plate 1 is in the "fully-folded state" The load supporting plate 1 is located in the region where the horizontal protecting plate 3 is covered as shown in Fig. In the embodiment illustrated in the drawing, as described above, the drive wire 91 is loosened in a state in which a strong tensile force is applied by the tension spring 92 to pull the second outermost load supporting plate 1b in the front direction of the landing All of the load supporting plates 1 including the second outermost load supporting plate 1b are rotated in the direction of the front of the landing platform by the tensile force, so that they are in the "completely folded state" as described above.

In the folded state of the load supporting plate 1, the rotating lid plate 2 is in the vertical state, and the load supporting plate 1 in the folded state is covered and protected by the rotating lid plate 2 In addition, because there is enough room for the train to enter, the train can safely enter the platform without any problem.

When the situation that the train vehicle enters the platform and stops and the passengers are to ride on the train vehicle comes up, the load support plate 1 is gradually unfolded in the fully folded state.

Figs. 14 and 15 are schematic perspective views showing different directions in which the rotating lid plate 2 is horizontally arranged as the load supporting plate 1 is unfolded in the folding type safety footrest 100 according to the present invention And Fig. 16 shows a schematic plan view of the state shown in Fig. 17 and 18 show a state in which the load supporting plate 1 is further unfolded in the folding type safety footrest 100 according to the present invention so that the gap closing member 5 is projected beyond the width of the rotation lid plate 2 in the lateral direction There is shown a schematic perspective view showing a different view direction, and Fig. 19 is a schematic plan view of the state shown in Fig.

In order to unfold the load supporting plate 1, in the embodiment shown in the drawing, the driving motor 9 is operated to pull the driving wire 91, so that the first outermost load supporting plate 1a and other load supporting plates (1) simultaneously rotate away from the front of the platform. As the load supporting plate 1 rotates, the rotation supporting plate 1 is pushed up by the rotating lid plate 2 which is vertically rotated. As a result, Is horizontally disposed in a horizontal state with the horizontal protection plate (3) in a state of being supported by the load support plate (1). After the rotation lid plate 2 is thus in a horizontal state, the load supporting plate 1 is further rotated and unfolded as shown in Figs. 17 to 19 so that the load supporting plate 1, which is provided at the lateral outer edge of the load supporting plate 1 The gap closing member 5 further projects laterally outward than the rotation lid plate 2 while maintaining a state in which it is rotated relative to the load support plate 1 and is originally oriented in the longitudinal direction.

When the train vehicle stops at the platform, the gap closing member 5 is brought into close contact with or as close as possible to the lateral side of the train vehicle, so that the gap between the gates of the train vehicle and the platform, , The rotary cover plate 2 and the horizontal protection plate 3 so that the passengers can safely get on and off without falling off, sticking in a cane or a shoehorn.

If the distance between the landing platform 200 and the transverse side of the train vehicle is large, the load supporting plate 1 is in the fully extended state as shown in Figs. 1 and 2, When the clearance is small and the distance between the landing platform 200 and the transverse side of the train vehicle is narrow, the load supporting plate 1 is not in the fully unfolded state as shown in Figs. 17 to 19, The closing member 5 is projected further in the lateral direction than the rotating lid plate 2 and comes into contact with the lateral side of the train car. As described above, the distance between the landing platform and the train car may be different due to the tolerance depending on the ascending / descending position in each platform and in one platform. In the present invention, the load supporting plate 1 The load supporting plate 1 is spread out to a degree different from each other depending on the loading / unloading position, so that the gap closing member 5 is extended in a direction in which the load supporting plate 1 is relatively unfolded And it is brought into close contact with the train car.

As described above, even if the distance between the front of the landing platform 200 and the lateral side of the train vehicle is different at each landing position in each station and in one history as described above, the degree of spreading of the load supporting plate 1 is adjusted accordingly So that the spacing member 5 is brought into contact with or as close as possible to the transverse side of the train car, thereby eliminating clearance where the cane or the shoe heel is missing. That is, in the safety footrest according to the present invention, the length in the lateral direction is automatically adjusted in accordance with the distance between the front face of the landing platform 200 and the lateral side face of the train vehicle so that the interval closing member 5 is brought into close contact with the train vehicle, It is possible to effectively prevent the passengers from getting out of the vehicle, and it is possible to further improve the convenience of getting on and off the passenger.

When the load supporting plate 1 is in the unfolded state, the load supporting plate 1 stands upright and supports the lower surface of the rotating lid plate 2. Thus, according to the present invention, when the passengers get on and off, Even if the load by the passengers is large, the rotating lid plate 2 can be securely supported by the load supporting plate 1 without being displaced downward or deformed. Therefore, according to the present invention, the stability at the time when the passenger ascends and descends the train can be greatly improved. The state in which the load supporting plate 1 supports the lower surface of the rotating lid plate 2 continues until the rotation lid plate 2 is horizontally expanded to the fully extended state of the load supporting plate 1. [

When the door of the train vehicle is closed and the passengers are no longer able to get on and off, the load supporting plate 1 is rotated so as to be in the fully folded state as described above, The rotary lid plate 2 is rotated downward again to be in the vertical position.

As described above, the folding type safety footrest 100 according to the present invention includes a plurality of load supporting plates 1, which are vertically erected on a lower surface of the rotating lid plate 2, which allows a passenger to step on and descend to apply a load It is possible to stably maintain the rotation lid plate 2 in a horizontal state without generating a downward deflection or deformation which is unfavorable to the rotation lid plate 2, Has the advantage of being. In a state in which the passenger does not need to ascend or descend, that is, in a state where the train does not enter the platform, or the passenger can not ascend and descend even if the train has entered the platform, the load support plate 1 is close to the platform And the rotary lid plate 2 is also rotated downward to be in a vertical state, so that it does not interfere with the running of the train car.

Particularly, even when a failure occurs in a state in which the load supporting plate 1 is in the unfolded state and accordingly the interval closing member 5 protrudes more than the horizontally rotatable cover plate 2, the train vehicle enters The load supporting plate 1 is automatically rotated in the folded state while the gap closing member 5 is in contact with the train vehicle, thereby effectively preventing collision between the train vehicle and the safety footrest. Accordingly, the folding type safety footrest 100 of the present invention has better stability than the prior art.

Above all, the folding type safety footrest 100 according to the present invention has an advantage that the platform can be assembled on the front of the platform without being blocked out. The horizontal support plate 3 and the load supporting plate 1 can be easily installed in a simple manner by being attached to the front face of the landing or by fixing them using an anchor or the like. It is not necessary at all. Therefore, the folding type safety footrest 100 of the present invention can be installed quickly and easily, and can be easily applied not only to a new landing platform but also to a conventional landing platform.
