Definitions

• the invention relates to a railway platform screen door and a screen wall for a railway platform, in particular but not exclusively for an underground or subsurface railway.
• the conventional railway station consisting of a raised platform adjacent to the track is essentially the same design as has been used since the beginning of the railway industry in the nineteenth century and is an effective solution to the problem of maximising passenger boarding speed.
• Platform screen systems or automated platform gates are well known in the railway industry as one approach of dealing with these problems. Due to the problem of lining up doors on the platform and the train, these systems are usually only installed on lines where the rolling stock is standardised, which in practice is on metro or underground systems, although some dedicated high speed systems are also provided with screens.
• the commonest type is a full height system (e.g. around 2m high or more vertical screens).
• the full height system is usually adopted for newly built railway systems and is in practice essential in air- conditioned systems as otherwise the air conditioning system loses air to the rail tunnels, which is highly inefficient.
• a half height screen or gate This consists of a rigid vertical screen and gate, usually about lm30 high, which permits the air-conditioning solution provided by the passage of the train to be used and reduces the problems caused by litter and people falling onto the track.
• accidents and suicides still happen on these systems and they have not been adopted widely.
• An example of such a system is described in EP 1386813.
• the present invention therefore seeks to provide a platform screen and platform screen door that solves these problems.
• barrier for a railway platform which platform has a surface and an edge comprising a first wall surface facing away from the platform edge and a second wall surface facing the platform edge, a top edge connecting the first and second wall surfaces, wherein at least one of the first or second wall surfaces is inclined or shaped at least in part away from a vertical plane perpendicular to the platform surface such that, in the installed position, the distance between the vertical plane defined by the platform surface and edge and a vertical plane defined by the platform surface and the wall surface remote from the platform edge is greater than the distance between the first and second wall surfaces adjacent to the top edge.
• the first and/or second wall surfaces are curved away from the platform edge.
• the spatial separation of the first and second walls at their respective bottom edges is sufficient that the barrier is adapted to house the drive mechanism for a sliding door.
• the barrier is adapted to receive a sliding door, which may have a substantially similar profile to the barrier.
• the lower part of the first wall surface is angled away from the plane of the surface of the remaining part of the wall so as to keep passengers away from the platform edge.
• the barrier has a height between 1100 and 1500mm from the platform surface.
• the invention also provides for a door for a barrier system for a railway platform, wherein the door in the installed position is curved away from the platform edge.
• Fig. 1 shows a first profile of a platform screen door system
• Fig. 2 shows a second profile of a platform screen door system
• Fig. 3 shows a third profile of a platform screen door system
• Fig. 4 shows a fourth profile of a platform screen door system
• Fig. 5 shows a fifth profile of a platform screen door system
• Fig. 6 shows a sixth profile of a platform screen door system.
• Figure 1 shows a profile of a platform screen door system comprising a barrier section 1 housing a gate 2.
• the barrier section 1 comprises a first wall 3, which in use will face the platform, the first wall 3 being slightly inclined to the vertical and a second wall 4, which in use will face away from the platform towards the platform edge, which wall is inclined at a substantially greater angle to the vertical than the first wall 3.
• the two walls 3, 4 are joined by a generally curved cap 5. The effect of the different angles of the first and second walls is that the apex of the cap 5 is located closer to the vertical plane of the bottom edge 6 of the first wall 3 than to the vertical plane bottom edge 7 of the second wall 4.
• the gate 2 is housed within the barrier section 1 and is mounted at an angle to the vertical substantially parallel to that of the section wall 4 so that in the closed position the top of the door is substantially as far away from the vertical plane of the platform edge as the top of the barrier.
• the drive mechanism for the door can be housed in the base of the barrier section adjacent to the lower edge of the door 2.
• Figure 2 shows an alternative architecture to the system of Figure 1, again comprising a barrier section 11 housing a door 12.
• the wall 14 facing the platform edge 14 is in this case curved away from the platform edge and the door 12 shares a similar curved profile.
• the wall 13 facing the platform comprises a stepped lower portion 15, which is generally curved in the opposite direction to the wall 13 and an upper curved portion 16 which is curved in the opposite direction and is substantially concentric with the curved wall 13.
• the stepped lower portion 15 enables the drive gear to be house within the barrier section 11.
• Figure 3 shows a further alternative architecture to figures 1 and 2 again comprising a barrier section 21 housing a door 22.
• the wall 24 facing the platform edge is generally planar but angled to the vertical away from the platform edge such that the top of the barrier section is located spatially more distant from the vertical plane of the platform edge than the bottom edge 26 of the wall 24.
• the wall 23 facing the platform is in this case curved such that the bottom edge 27 of the wall 24 is located further away from the vertical plane of the platform edge than the top of the barrier.
• the door 22 is in this case curved so that it is substantially concentric with the curved wall 23.
• the drive gear is located in the space between the lower edge of the door 22 and the bottom edge 26.
• Figure 4 shows a further alternative architecture to that of figures 1 to 3 again comprising a barrier section 31 housing a door 32.
• the wall 34 facing the platform edge is generally planar but angled to the vertical away from the platform edge such that the top of the barrier section is located spatially more distant from the vertical plane of the platform edge than the bottom edge 36 of the wall 34.
• the wall 33 facing the platform is in this case curved such that the bottom edge 37 of the wall 34 is located further away from the vertical plane of the platform edge than the top of the barrier.
• the top part of the barrier 31 is in this case lipped so that there is a small overhang over the wall 33.
• the door in figure 4 has a more complex profile than the doors of figures 1 to 3.
• the profile of the door side facing the platform is generally curved being again substantially concentric with the curve of the wall 33.
• the rear face of the door however has two parts to the profile.
• the upper part of the profile 38 is generally curved and substantially concentric with the front face, whereas the lower part of the profile 39 is generally angled away from the curve of door so as to form a generally triangular cross-section.
• the embodiment of figure 5 comprises again a barrier section 41 housing a door 42.
• the wall 44 which in use faces the platform edge is substantially vertical.
• the wall facing the platform in the installed position comprises a first upper portion 45 which is substantially vertical and parallel to the wall 44 and a lower portion 46, which is generally convex curved away from the wall 44 and towards the platform surface.
• the top of the barrier is curved in a similar manner to the barriers of figures 1 to 3.
• the embodiment of figure 6 is substantially the same as the embodiment of figure 5, save that the top of the barrier is substantially the same as the top in figure 4.
• the drive gear is located in the space between the door and the lower curved portion of the wall 46.
• the distance between vertical planes transecting the fore and rearmost points of the barrier is greater than the distance between the first and second wall surfaces.
• the screen and door designs of figures 1 to 6 address this issue by having their upper edge further away from the platform edge than the bottom edge of the screen facing the platform edge.
• a passenger leaning over the edge by 300mm does not encroach beyond the edge of the platform.
• the stepped portion or curved portion further forces passengers further away from the edge. Due to the comparatively small angle the advantages of the lower height door systems are maintained without increasing the risk of creating a claustrophobic effect on passengers but the safety problems inherent in the use of a lower height barrier are greatly reduced.
• the barrier and gate can be made from a variety of materials including aluminium extrusions or plastic materials.
• the barrier can be manufactured so that the respective first and second walls form part of a single structure or the walls can be made separately and joined together.
