The The first fixed platform 48 extends transversely from the first access door 22 to the movable platform 52, and has a dimension, in the transverse direction, sufficient to allow a wheelchair user to maneuver freely and freely. autonomous. The second fixed platform 50 extends transversely from the second access door 24 to the mobile platform 52. Thus, the mobile platform 52 extends transversely between the first 48 and the second 50 fixed platform. The dimensions of the mobile platform 52 are greater than those of a wheelchair of a user. Advantageously, the transverse dimension of the mobile platform 52 is greater than 80 cm, preferably between 80 cm and 120 cm. According to a variant not shown, in which the vehicle comprises a single fixed platform on which the first access door 22 opens, the mobile platform 52 extends between this single fixed platform and the second access door 24. mobile platform 52 comprises a plate 54 and a movement mechanism 56 of this plate 54 relative to the body 4 of the railway vehicle.

The displacement mechanism 56 moves the plate 54 between a high position flush with the first fixed platform 48 and a low position flush with the lower floor 44 of the lower passenger compartment 6. The displacement mechanism 56 comprises a motorized member 58 moving the plate 5. 54 relative to the body 4 and a manual actuator 60 independent of the motorized member 58. The manual actuator 60 is able to move vertically the plate 54 of the mobile platform without electricity. It is for example used in the event of failure of the motorized member 58. The manual maneuvering member 60 is a jack type lifting device. The hoisting apparatus 10 is preferably a hydraulic jack, a jack with a rack and pinion, a jack with a pinion and a worm, and so on. Alternatively, the manual actuator 60 includes any type of apparatus for moving vertically the plate 54 relative to the lower floor 44 manually.

The displacement mechanism 56 optionally comprises at least one position sensor 62 of the plate 54 relative to the body 4. The or each position sensor 62 is able to detect the plate 54 of the mobile platform 52 in the low position and in high position. The or each position sensor 62 is advantageously a sensor of the electric sensor type, mechanical limit switch sensor or any other type of detection sensor with or without contact. In the high position, the plate 54 completes a spacing between the first 48 and the second 50 fixed platform. The plate 54 then forms a channel between the first 22 and second 24 access doors. In addition, the plate 54 in the high position partially closes the access to the toilet module 38.

In the low position, the plate 54 releases a gap between the first 48 and the second fixed platform 50 and defines an access path 46 between the lower floor 44 of the lower passenger compartment and the toilet module 38. The second fixed platform 50 is inaccessible to wheelchair users. Alternatively, the movable platform moving mechanism 56 provides the wheelchair user lift function between the first level 10 and the second level 12. In accordance with the invention, the ramp 32 extends between the first fixed platform 48 of the second level 12 and the lower floor 44 of the first level 10. The ramp 32 comprises for example an intermediate bearing 63 and two inclined planes 64, 66 connecting for one, the first fixed platform 48 at the intermediate level 63 and for the other, the intermediate bearing 63 to the lower floor 44.

The transverse dimension of the ramp 32 is advantageously greater than the size of a wheelchair, preferably greater than 80 cm and advantageously between 80 and 120 cm. Each inclined plane 64, 66 has an access slope sufficiently low to allow access between the first and second levels 10, 12 to the wheelchair users independently. The inclination of the inclined planes is advantageously between 3 ° and 9 °. As illustrated in FIG. 2, at least one step 34 is arranged between the second fixed platform 50 and the lower floor 44. The step or steps 34 define an auxiliary traffic lane for pedestrian users wishing to travel between the first level 10 and the second level. second level 12 during the use of the platform 52. Thus, thanks to the step or steps 34, the passageway formed by the ramp 32 can be reserved for wheelchair users, pedestrian users preferentially borrowing the auxiliary route by the In other words, the circulation of wheelchair users does not hinder the movement of pedestrian users, and vice versa. As illustrated in Figure 2, the rail vehicle 1 comprises a movable anti-tilt system 67, disposed between the first 10 and the second level 12 of the first stage. This anti-tilt system 67 is intended to ensure the safety of users, by preventing the risk of falling between the first 10 and the second 12 level. The anti-tilt system 67 comprises for example two gates 68, 70, one interposed between the mobile platform 52 and the first fixed platform 48, and the other interposed between the mobile platform 52 and the second fixed platform 50. The system anti-tilt 67 also includes a motorized hinge 72 providing mobility to the two gates 68, 70 between a first and a second configuration, and a mechanical coupling system 74, synchronizing the first and second configurations at the position of the mobile platform 52 More particularly, the coupling system 74 synchronizes the first configuration with the low position of the mobile platform 52 and the second configuration with the high position of the mobile platform 52. Thus, the first configuration corresponds to the low position of the platform mobile 52. In this first configuration, the two gates 68, 70 are interposed, one between the mobile platform 52 and the first fixed platform 48 and the other between the mobile platform 52 and the second fixed platform 50. The anti-tilt system 67 35 then prohibits access to the mobile platform 52 in the lower position from the first 48 or second platform fixed 50.

The second configuration corresponds to the high position of the mobile platform 52. In this second configuration, the two gates 68, 70 are interposed between the mobile platform 52 and the lower floor 44. The anti-tilt system 67 then prevents a fall. a user from the mobile platform 52 in the high position 5 to the lower floor 44 of the first level. The motorized articulation 72 moving the gates 68, 70 is advantageously an electric geared motor. In a variant, the motorized articulation 72 comprises any other type of mechanism that can drive a gate in rotation.

The coupling system 74 is advantageously a belt pulley type transmission system. The pulleys are linked on the one hand to the movement mechanism 56 of the platform 54 of the mobile platform and on the other hand to the articulation 72 of the gates 68, 70. In a variant, the coupling system 74 comprises any other type of chain. transmission synchronizing the movements of the plate 54 of the mobile platform with the hinge 72 of the gate. The rail vehicle 1 further comprises a control unit 76, controlling the position of the platform 54 of the mobile platform and the use of the toilet module 38.

The control unit 76 is connected on the one hand to the position sensor 62 of the mobile platform and on the other hand to the sensor 42 to detect the user at the toilet module. The control unit 76 controls the position of the mobile platform 52 according to the travel conditions of the railway vehicle 1.

When the railway vehicle 1 arrives at the station stop, the control unit 76 actuates the movement of the mobile platform 52 in the up position. On the other hand, during the journey, the control unit 76 actuates the movement of the mobile platform 52 in the low position. The control unit 76 simultaneously checks for the presence of the user in the toilet module 38. The unoccupied toilet module 38 remains inaccessible to the users during a station stop. In the presence of a user in the toilet module 38, the control unit 76 waits for the exit of the user to actuate the mobile platform 52 in the up position and to close the access to the toilet module 38. A first mode embodiment implemented in a railway vehicle 1 will now be described.

Initially, the railway vehicle 1 is at the station and authorizes access to the users to the lower passenger compartment 6 and upper 8, via the access zone 20. The mobile platform 52 is in the up position. The anti-tip system 62 is in the second configuration. Access to the toilet module 38 is closed.

The users access the railway vehicle 1 by the first 22 or the second 24 access door of the railway vehicle 1. In the case of an access by the first door 22, the users arrive at the first fixed platform 48. The users in a wheelchair take the ramp 32 to reach the lower passenger compartment 6 at the first level.

In the case of an access by the second door 24, the users arrive at the second platform 50 fixed. The wheelchair users traverse the mobile platform 52 in the high position, reach the first fixed platform 48 and use the ramp 32 to reach the lower passenger compartment 6. The pedestrian users access the lower passenger compartment 6 by 15 respectively taking the ramp 32 since the door 22 and the steps 34 from the door 24 between the first and the second level 10, 12 of the first floor. To reach the upper passenger compartment 8, the pedestrian users take the staircase 30. At the start of the journey of the railway vehicle 1, the mobile platform 52 passes in low position, synchronously the gates 68, 70 of the anti-tilt system which go into the first configuration. The access path 46 for the toilet module 38 is open. Users have access to the toilet module 38 by borrowing the passage defined by the mobile platform 52 in the low position.

Before a stop at the station, the control unit 76 checks the presence of users at the toilet module 38 with the presence sensor. When the toilet module 38 is unoccupied, the control unit 76 controls the closure of the toilet module 38 and actuates the movement of the mobile platform 52 in the high position. In a synchronized manner, the gates 68, 70 of the anti-tilt system pass into the second configuration. In the station, wheelchair users take the opposite path. They reach the access zone 20 via the ramp 32. When the mobile platform 52 is in the up position, the wheelchair users access either the first 22 or the second 24 access door.

The pedestrian and wheelchair user flows are distributed on each side 26, 28 of the railway vehicle. The wheelchair users use the ramp 32. The pedestrians 30.24.2 use indifferently the ramp 32 or the steps 34 to reach the access zone 20. The pedestrian users are divided between the two routes depending on the influx. In addition, when the moving mechanism 56 of the mobile platform is defective, an operator navigating the railway vehicle 1 actuates the manual actuator 60 for positioning the plate 54 of the mobile platform to the desired position. The two-stage railway vehicle 1 provides access for wheelchair users to their reserved location in the lower passenger compartment 6 in a stand-alone manner and has a universal toilet module 38 which is level on the first floor level 10 without modification. 8. The fixed ramp 32 ensures access to the lower passenger compartment 6 for wheelchair users between the first level 10 and the second level 12 of the first floor, by the ramp 32. The ramp 32 makes it directly accessible to the first and second 15 access doors 22, 24 through the mobile platform 52 interposed. The mobile platform 52 in the high position provides an interconnection between the first and second doors 22, 24 access and fits in the low position, an access route 46 to the toilet module 38. The rail vehicle 1 ensures an optimized circulation of users between the 20 access doors 22, 24 and the lower passenger compartment 6. The railway vehicle 1 presents a first preferred way for the wheelchair users to move independently and a second auxiliary lane for pedestrian users able to use the steps 34 The layout of the access routes allows the possibility of separating pedestrian and wheelchair user flows to optimize access to the rail vehicle 1. The rail vehicle 1 ensures reliability in the use of the ramp 32 fixed and secondly by the actuator 60 of the mobile platform 52 manually in the event of failure of the motorized member 58. It will be noted that The invention is not limited to the embodiment which has just been described, but could have various variants. In particular, the railway vehicle could have only one floor.
