Definitions

  • the present invention relates to devices used for filling the gap existing between a railway vehicle and the platform.
  • the platform gap also called PTI "platform train interference" is the separation existing between the side of a railway vehicle body and the end of the platform from which passengers access the vehicle.
  • the platform must be aligned with the floor of the railway vehicle on which passengers travel; in some cases, there is a slight difference in height, but in any case, there must be a separation between the platform and the railway vehicle in order to allow vehicles to move freely without interfering with the platform.
  • platform gap filler devices which can be arranged in the vehicle or directly in the platform are known.
  • Platform gap filler devices for railway vehicles are arranged in the region of the vehicle doors and can be movable with respect to the vehicle or fixed with respect to the vehicle.
  • Movable filler devices are concealed when the vehicle is running and configured for performing an emerging movement and covering the platform gap when the vehicle arrives at the station, allowing passengers to get on and off the vehicle safely. These devices are operated by electric, pneumatic, or hydraulic drives and are, in general, mechanically complex and involve a high manufacturing and maintenance cost.
  • the dimensions of the bridging element must be designed so that the vehicle complies with the railway gauge of the track through which the vehicle runs, particularly so that the cross-section of the vehicle does not interfere with any track element. In practice, this leads to fixed devices not completely covering the separation between the platform and the vehicle, and therefore not being completely satisfactory in terms of safety and comfort. This problem is exacerbated in curved platforms, where the separation between the vehicle and the platform can be larger in some areas.
  • EP3473513A1 shows a railway vehicle with platform gap filler devices.
  • the device comprises a bridging element extending in a longitudinal direction and coupleable to the outside of the railway vehicle below the region of a door of the vehicle in order to minimize the separation between the railway vehicle and the platform, a retractable element which is partially housed in a gap of the bridging element and which is configured to be translationally movable in a transverse direction, which is perpendicular to the longitudinal direction, between a retracted position and an extended position in which the retractable element protrudes from the bridging element, and spring means arranged in the gap of the bridging element, between the bridging element and the retractable element, to force the retractable element towards the extended position.
  • the bridging element is coupled by means of guides to the vehicle doors, such that the drive of the doors is utilized to move the bridging element; therefore, when the vehicle doors open, both the bridging element and the retractable element emerge from below the region of the door and move in the transverse direction to contact the platform, and when the doors are closed, both the bridging element and the retractable element are concealed.
  • the retractable element 120 contacts the platform 2, as shown in Figures 5 and 7 , the free ends 134 and 135 of the bar 131 move together with the retractable element 120, with each segment 132 and 133 of the bar 131 being compressed between the central region 112 of the bridging element 110 and the respective free end 134 and 135 thereof.
  • the bar 131 recovers its shape and the free ends 134 and 135 of the bar 131 move, driving the retractable element 120 from the retracted position P1 to the extended position P2.
  • the bar 131 therefore has a crossbow-like behavior, wherein the two bar segments 132 and 133 guide the retractable element 120 between the extended position P2 and the retracted position P1.
  • the retractable element 120 has a shape corresponding to the gap 111 of the bridging element 110, and the retractable element 120 has beveled edges 123 at its ends 121 and 122. Those edges 123 generate an oblique surface with respect to the longitudinal direction L which allows the impacts suffered by the retractable element in the longitudinal direction L to be gradually absorbed.
  • Figure 6 shows the moment prior to the contact of the platform 2 with the edge 123 of the end 121 of the retractable element 120.
  • the edges 123 and the curvature segments 136 and 137 therefore help to ensure gradual forces in the longitudinal direction, increasing the service life of the device 100.
  • the retractable element 120 has beveled edges at the two ends 121 and 122 of the retractable element 120 since the railway vehicle can run equally in the two directions of travel.
