Definitions

  • the present invention relates to a step with retractable steps for an access door to a rail passenger vehicle, from or to platforms at at least two different levels.
  • the plaintiff has manufactured for the wagons of the very high speed line Paris-Lyon a step comprising a fixed lower step and a movable upper step around a horizontal axis between a position returned inside the wagon and a position horizontal exit , under the effect of a jack acting on an articulated polygon connected to an arm making a fixed angle with the surface of the movable step, against the resistance of a spring, until a position is exceeded in neutral beyond which the spring tends to maintain walking either in the extended position or in the retracted position at rest.
  • the document EP-A-0 118 400 describes a step with two retractable steps, one of which undergoes a horizontal translation under the effect of a first jack, and the second a 90 ° rotation under the effect of a second cylinder, the movements of the two steps being independent.
  • Such steps are however not suitable for allowing passengers to get on and off from or to platforms of different heights above the track, in conditions of sufficient comfort for the vast majority of the public, in particular for young children or the elderly.
  • the very high speed train projects for the North of France intended to use the Belgian and English networks and the Channel Tunnel, require the provision of fully retractable steps, allowing the public to get on and off easily cars, with station platforms higher than those of the French network of 210 mm for the Belgian network and 365 mm for the English network, the distance between the edge of the vehicle body and the edge of the platform is also significantly less for the English network than for the French and Belgian networks.
  • the present invention therefore aims to provide a step with fully retractable steps allowing easy access of the wagons to the vast majority of the public in stations of different platform levels and with spacings between the profile of the wagons and the edge of the different platform, a step lower not exceeding the lateral spacing of the upper step in the extended position in the case of stopping in stations with the highest platforms, while forming counter step, so as to leave only a small interval between the edge of the upper step and these platforms, while adapting the profile of the wagon to that of such platforms.
  • Figure 1 shows in vertical section the step in the retracted position, door closed, while the train is running.
  • Figure 2 shows in vertical section the step in the access position to a platform of the highest level (eg platform of the British network), door open, the upper step alone being accessible to travelers.
  • a platform of the highest level eg platform of the British network
  • Figure 3 shows in vertical section the step in the access position to docks of a lower level, the lower step being at a quay of intermediate height (for example quay of the Belgian network) and halfway up between the upper step and an even lower platform (eg platform on the French network).
  • a quay of intermediate height for example quay of the Belgian network
  • an even lower platform eg platform on the French network
  • Figure 1 are represented three platform levels 1 (for example of the British network), 2 (for example of the Belgian network) and 3 (for example of the French network) and the floor 3A of the vehicle in front of the door 3B.
  • the access door being closed, the upper step 4 is tucked inside the body and the lower step 13 extends the door downwards by its lower surface.
  • a helical spring 12 is fixed on the one hand to an arm 8 linked to the fixed axis 9, on the other hand to the end d 'a connecting rod 12A carried by a fixed axis 12B.
  • a second helical spring 19 is fixed on the one hand to an arm 19A linked to the movable axis 23, on the other hand to the end of the connecting rod 18 beyond its pivot point 18A on the middle part of the bottom step 13.
  • the rear part of the upper step 4 is connected by a link 20 to the support 21 of a door seal 22, here applied against the bottom of the door.
  • FIG. 2 represents the position that the step takes when the train arrives at a station whose platform is on the upper level 1.
  • the door 3B is released laterally and takes the position 3C.
  • the cylinder 6 pushes the arm 8A and rotates around the axis 9 in a clockwise direction the connecting rod 10, driving up the rear end of the arm 11, which also pivots around the movable axis 23.
  • the arm 11 rotates around the movable axis 5 the upper step 4, which, turning around this axis, partially exits the body and comes into the horizontal position, at a level slightly higher than that of the platform 1.
  • the connecting rod 14, linked to the movable axis 23, drives the lower end 15 of the lower step 13 towards the inside of the body and upwards, the upper end 17A of which is pushed back by a stop. integral with the upper step 4, so that the lower step 13 forms a counter step below the end of the upper step.
  • the latter is held in the extended position by the spring 12, which, driven by the arm 8 secured to the rotary axis 9, has passed the neutral position with respect to this axis and is opposed to any return of step 4 to its original position.
  • the spring 19, linked on the one hand to an arm 19A secured to the movable axis 23, on the other hand to the end of the rod 18 fixed to the middle part of the step 13, maintains the latter in its new position.
  • the upper step 4 in its rotation drives the link 20, which pivots the support 21 of the door seal 22 backwards and releases the opening of the door.
  • FIG. 3 represents the position of the step when the train arrives at a station whose platform is at a lower level 2 or 3.
  • the jack 17, pushing the arm 16 linked to the rotary axis 23, makes pivot the connecting rod 14 clockwise around the axis 23, making the bottom end of the step 13 go upwards, the middle part of which remains connected by the connecting rod 18 to the axis 5
  • the step 13 therefore assumes a horizontal extended position, at the level of the platform 2 and halfway between the platform 4 and the platform 3. It is held in this position by the spring 19, which, driven by the arm 19A integral axis 23, has exceeded its neutral position vis-à-vis this axis and opposes a return of the step 13 to its initial position.
  • the compressed air circuit includes safety devices preventing the door from opening in normal operation if the step does not open.
  • the step is provided with a limit switch 24 for the top step, detecting the retracted position of the steps and authorizing the starting of the train only in the closed position of this contact.
  • the entire step is determined so that its center of gravity is vertical to axis 5 around which the upper step pivots during its maneuver.
