  • FR 2 976 891 a rail vehicle car comprising an access system comprising a rotary box whose upper surface forms, together with a sliding step in the box, a ramp between the car and the dock.
  • the box is particularly bulky.
  • the part of the body of the car that is in the vicinity of the access system requires special development.
  • the part of the box located under the box must be clear, so that the rotation of the box down is possible.
  • the installation of the access system on a pre-existing car is then complex and expensive, or even unfeasible.
  • One of the objects of the invention is to provide a simple access system, inexpensive and easy to install.
  • the invention relates to a rail vehicle car of the aforementioned type, characterized in that the access system comprises a threshold extending from the floor and rotatably mounted relative to the floor around a second horizontal axis , the first axis being offset from said second axis, the threshold resting on the frame so that the rotation of the frame about the first axis causes the rotation of the threshold around the second axis.
  • the Figure 1 illustrates a car 2 of a railway vehicle according to the invention.
  • the car 2 comprises a box 4 forming the lower part of the structure of the car 2 and on which is arranged a floor 6 for the circulation of the passengers in the car 2.
  • the floor 6 is substantially flat and horizontal and extends according to a longitudinal direction D of the car 2.
  • the car 2 also includes an access door 8 and an access system 10 allowing the passengers to get on and off the car 2 through the access door 8, in particular to reach a railway platform 12 whose edges are hatched on the Figure 1 .
  • the platforms 12 do not all have the same height, and the spacing between the rails and the platform 12 is also different from one platform 12 to another.
  • the spacing of the platform to the rails and the platform height are variable from one portion of the platform to the other.
  • the horizontal 14 and vertical 16 gaps ( Figure 2 ) between the platform 12 and the car 2, which correspond to the horizontal spacing, respectively vertical between the platform 12 and the car 2 are variable.

  • the threshold 17 forms a tilting ramp for passenger traffic between the edge of the car 2 and the floor 6.
  • the threshold 17 is in the form of a rigid board, rectangular and substantially flat.
  • the threshold 17 is rotatably mounted relative to the floor 6 around a second axis Y at one of its edges.
  • the second axis Y is parallel to the longitudinal direction D and the first axis X.
  • the threshold 17 is displaceable in rotation between a high position in which the threshold 17 forms a slope less than or equal to -8% with the horizontal plane passing through the second axis Y, and a low position in which the threshold 17 forms a slope greater than or equal to + 8% with the horizontal plane passing through the second axis Y.
  • the threshold 17 has a dimension along the longitudinal direction D which is substantially equal to the width of the frame of the access door 8. In addition, the threshold 17 extends substantially from the floor 6 to the edge of the 2. The threshold 17 is supported on the frame 18 at its free edge opposite the second axis of rotation Y, so that the rotation of the frame 18 about the first axis X causes the rotation of the threshold 17 around the second axis Y.

  • the first axis X and the second axis Y have a relative position such that the high position of the frame 18 corresponds to the high position of the threshold 17, and such that the low position of the frame 18 corresponds to the low position of the threshold 17.
  • first axis X is shifted laterally from the center of gravity of the frame 18 towards the opposite edge of the car 2, so that the end of the frame 18 which is directed towards the platform 12 tends to pivot towards the bottom of the body 4 under the effect of the weight of the frame 18.
  • the frame 18 comprises support pads 20 on which the threshold 17 rests and on which the threshold 17 slides when the frame 18 pivots. This is described in more detail in the following.
  • the frame 18 comprises three support pads 20.
  • the support pads 20 are located on the upper face of the frame and near its edge oriented towards the platform 12.
  • Each support pad 20 presents itself in the form of a ring or disc portion and protrudes from the upper face of the frame 18.
  • the threshold 17 rests on the frame 18 via a link rectilinear linear.

  • the carriage 32 also comprises a support roller 35 at contact of the conversion mechanism 26.
  • the conversion mechanism 26 comprises a guide surface 36.
  • the guide surface 36 is integral with the body 4 of the car 2.
  • the guide surface 36 is in contact with the support roller 35. More specifically, the support roller 35 bears on the guide surface 36 and is displaceable along the guide surface 36. The support roller 35 is held pressed against the guide surface 36 under the effect of the weight of the frame 18.
  • the guide surface 36 comprises three straight guide portions 38, 40, 42.
  • the guide surface 36 thus forms a guide path of the support roller 35 which is continuous.
  • the second and third guide portions 40, 42 are located on either side of the first guide portion 38.
  • the rotation of the frame 18 is induced by the displacement of the carriage 32 and the support roller 35 along the guide portions 38, 40, 42.
  • the second and third guide portions 40, 42 are respectively associated with a given direction of rotation of the frame 18.
  • the direction of rotation of the corresponding frame 18 is a function of the inclination of the guide portions 40, 42, which is the same for the two guide portions 40, 42.

  • the second guide portion 40 is associated with the direction of frame rotation 18 in which the edge of the frame 18 facing the platform 12 pivots towards the bottom of the body 4, and the third guide portion 42 is associated with the other direction of rotation of the frame 18.
  • the second and third guide portions 40, 42 are inclined so as to form a negative slope with respect to the floor 6.
  • the inclination of the second and third guide portions 40, 42 is chosen according to the characteristics of the actuator 28.
  • the actuator 28 is integral with the frame 18 and is able to set the control member 24 in motion.
  • the actuator 28 is a linear actuator extending substantially in the direction of sliding C. More specifically, the actuator 28 is a jack comprising a piston and a rod whose end is fixed to the carriage 32 and whose other end is engaged in the piston.
  • the access system 10 comprises a step 44 slidably mounted in the frame 18 and a support nose 45.
  • the step 44 is adapted to fill the horizontal gaps 14 and vertical 16 between the car 2 and the platform 12.
  • the step 44 comprises a pallet 46 substantially flat and slidably mounted in the frame 18 in a direction parallel to the plane P of the frame 18.
  • pallet 46 is slidably mounted between an extended position in which all or part of the pallet 46 forms an access ramp extending between the edge of the car 2 and the platform 12, and a retracted position in which the pallet 46 is retracted in the frame 18 and the step 44 does not protrude outside the car 2.
  • the support nose 45 is adapted to come into contact with the platform 12 in the deployed position of the step 44.
  • the support nose 45 is located at the end of the pallet 46 and is integral with the pallet 46.
  • the nose support 45 has a curved shape downwards.
  • the access system 10 further comprises a detection and control system 48 configured to evaluate the horizontal and vertical gaps 14 and to control the deployment of the step 44 and the actuation of the rotation mechanisms 22 as a function of the horizontal gaps 14 and vertical 16 detected. More specifically, the detection and control system 48 is configured to control the rotation mechanisms 22 and the step 44 so that the spacing between the edge of the platform 12 and the edge of the pallet 46 of the step 44 is less than or equal to at 15 mm, and preferably substantially zero.
  • the access door 8 When the car 2 is in circulation on a track, the access door 8 is closed, the step 44 is in the retracted position, the chassis 18 is in its rest position and the threshold 17 bears on the chassis 18.
  • the support roller 35 of the carriages 32 of the rotation mechanisms 22 is supported on the first portion 38 of the corresponding guide surface 36.
  • the detection and control system 48 detects the horizontal gap 14 and the vertical gap 16.
  • the detection and control system 48 controls the rotation mechanisms 22 simultaneously so as to adapt the inclination of the threshold 17 to the vertical gap 16.
  • the detection and control system 48 controls the linear actuator 28 to move the control member 24, which, via the associated conversion mechanism 26, rotates the frame 18 around the first axis X and modifies the inclination of the threshold 17.
  • the detection and control system 48 controls the displacement of the rod in the piston of the jack of the actuator 28, which is translated by the displacement of the carriage 32 in the associated slideway 30 via the guide roller 34.
  • the carriage 32 drives the support roller 35 along the guiding surface 36 in displacement.
  • the support roller 35 is moved along one or the other of the second and third guide portions 40, 42.
  • the support roller 35 is moved towards the second guide portion 40. Due to the inclination of the second guide portion 40 relative to the horizontal, the displacement of the support roller 35 results in a pivoting of the frame 18 around the first axis X towards the bottom of the body 4 under the effect of chassis weight 18.
  • the rotation of the frame 18 around the first axis X causes the displacement of the support pads 20 and the connection of the frame 18 to the threshold 17 towards the bottom of the box 4.
  • the threshold 17 thus pivots about the second axis Y, its opposite edge the floor 6 pivoting towards the bottom of the body 4, and slides on the support pads 20 due to the shift of the first axis X relative to the second axis Y.
  • the support roller 35 is displaced along the third guide portion 42.
  • Simultaneous control of the two rotation mechanisms 22 distributes the forces between the two mechanisms 22, as well as compensating the torque applied to the frame 18 by the actuator 28 of each rotation mechanism 22 and tending to rotate the frame around a vertical axis, which would result in harmful efforts applied to each of the carriages 32 if only one of the rotation mechanisms 22 was present.
  • the detection and control system 48 controls the deployment of the step 44 with respect to the frame 18 over a running length such that, when the frame 18 is pivoted, the nose 45 comes into contact with the dock 12 near its edge.
  • the ramps respectively formed by the pallet 46 of the step 44 and the threshold 17 are substantially in continuity with one another, and the horizontal and vertical gaps 14 and 14 are filled by the step 44.
  • the edge of the threshold 17 opposite the second axis Y and the pallet 46 are at a distance from each other less than or equal to 15 mm, and preferably are closer to one another. This makes it possible to limit the projection to move from the pallet 46 of the step 44 to the threshold 17, and thus to make this passage achievable by the persons to reduced mobility or wheelchair users (often referred to by the acronym UFR) without external assistance.
  • the edge of the pallet 46 of the step 44 and the edge of the platform 12 are located at a distance from each other less than or equal to 20 mm, and preferably are at the closest one of the 'other. This makes it possible to limit the projection to go from the platform 12 to the pallet 44, and thus to make this passage feasible for persons with reduced mobility or wheelchair users and without outside assistance.
  • the threshold 17 is adapted to form a slope of between -8% and + 8%. These values are prescribed and correspond to the limit values for slopes which people with reduced mobility or wheelchair users can cross without outside assistance.
  • the pallet 46 of the step 44 is retracted into the frame 18 and the frame 18 is pivoted by the rotation mechanisms 22 to its rest position, which brings the threshold 17 back to its initial position. .
  • the combination of the threshold 17 of the frame 18 and the setting in rotation of the threshold 17 around the second axis Y by the rotation of the frame 18 around the first axis X make it possible to reduce the deflection of the access system 10 during its operation, and therefore the development of the box 4 required for the operation of the access system 10.
  • the access system 10 is easier to install on existing cars, and can be installed on cars where known systems can not be installed.
  • the access ramp formed by the step 44 and the threshold 17 is easy to cross for people with reduced mobility or UFR (wheelchair users) without outside assistance, and this for a large number of platforms.
  • the rotation mechanisms 22 are of simple and reliable design because of the use of a conversion mechanism 26 converting the sliding movement of the carriage 32 into a rotational movement of the frame 18.
  • the provision of the first guide portion 38 has the effect that in the rest position of the frame 18, the force applied to the actuator 28 by the weight of the frame 18 is less.
  • first axis X and the second axis Y are offset vertically from each other so that in the rest position of the frame 18, the threshold 17 extends substantially horizontally. This makes it possible to minimize the rotation of the frame 18 to be made to move the threshold 17 to its high position or its low position, and thus to further limit the arrangement of the box 4 at the level of the access system 10.
  • the guide surface 36 of the rotation mechanisms 22 does not comprise a first guide portion 38.
  • the second and third guide portions 40, 42 are successive.
  • the guide surface 36 is integral with the frame 18.
  • the actuator 28 and the control member 24, that is to say the carriage 32 provided with the rollers 34, 35, are integral with the 4. More specifically, the slide 30 and the cylinder of the actuator 28 extend substantially horizontally.
  • the support roller 35 is located under the guiding surface 36 and takes the weight of the frame.
  • the threshold 17 comprises an inclined ramp 50 (dashed on the Figure 2 ) at its free end opposite the floor 6.
  • the ramp 50 extends substantially over the entire width of the threshold 17 and is adapted to facilitate the crossing of the jump formed between the threshold 17 and the pallet 44 and which is particularly due to the Threshold thickness 17.
  • the board forming the threshold 17 is slightly shortened so that the ramp 50 is fully in the car 2 when the access door 8 is closed.
  • the frame 18 comprises a support boss 52 replacing the support pads 20.
  • the boss 52 is located at the end of the upper face of the frame 18 which is oriented towards the platform 12.
  • the boss 52 extends over all or part of the width of the frame 18.
  • the threshold 17 rests on the boss 52 at a nip, so that the frame 18 and the threshold 17 are linked by a straight linear connection in the same manner as before.
  • the threshold 17 bears vertically on the frame 18 while being able to slide relative to the frame 18 to compensate for the relative movement of the threshold 17 and the frame 18 due to the offset of the first axis X and the second axis Y.
  • the guide surface 36 is mounted on the carriage 32 of the control member 24.
  • the control member 24 is slidably mounted on the frame 18.
  • the support roller 35 is not carried by the carriage 32.
  • the support roller 35 is integral with the body 4.
  • the guide surface 36 carried by the carriage 32 is supported on the support roller 35, so that the sliding of the carriage 32 causes the chassis 18 to rotate.
  • the displacement of the carriage 32 along the slide 30 induces the displacement of the guide surface 36 relative to the support roller 35, unlike the main embodiment previously described in which the carriage 32 moves the bearing roller 35 relative to the guide surface 36.
  • first axis X and the second axis Y are arranged such that the threshold 17 is in the up position or in the low position when the frame 18 is in the rest position. This makes it possible to eliminate the guide portion 38, 40, 42 of the guiding surface 36 corresponding to the direction of rotation of the frame 18 which is no longer required for the operation of the access system 10. As previously, this makes it possible to minimize the size of the actuators 28.
