Definitions

  • the present invention relates to a step structure for vehicles railway or road, in general, and relates, more particularly, to a device for control of the movement of an articulated step for access to a vehicle and on a device for accessing a vehicle, in particular a rail vehicle, comprising such a ordered.
  • Access devices to a vehicle of the prior art require the implementation work of a mobile step.
  • Document DE 94 03 982 shows a vehicle access device rail. This access device is articulated and retracts under the effect of a push horizontal induced by the door leaves, at the end of the closing phase of these leaves, the access device coming out automatically when the door leaves are opened.
  • the vehicle access device causes a movement of entering and exiting the access step using the wiggling of the door and the efforts induced by the door.
  • An object of the invention is to provide a movement control device an articulated access step to a vehicle and a vehicle access device, especially rail, whose general design allows full operation safety, and whose structure is simple and compact.
  • a device for controlling the movement of a step articulated vehicle access comprising a control arm, an arm intermediate and an exit or re-entry arm of the articulated access step, said control device causing a movement in and out of said articulated access step using the wiggle movement of the access door of said vehicle and the forces induced by said access door, a first end F of the control arm bearing against one of the leaves in the retracted position of the step, said intermediate arm being rotatably mounted by one of its ends on a second end E of the control arm, said output or re-entry arm of the articulated step being rotatably mounted by one of its ends B on the step articulated, said control device comprising at least one spring biasing the operating in the extended state, characterized in that said outlet or re-entry arm of said articulated step is rotatably mounted by the other of its ends C on the chassis of the vehicle and comprises two half-arms articulated by their ends D facing each other, said intermediate arm being rotatably mounted by one
  • An advantage of the device according to the invention is its simplicity, its reliability, its low cost, its absence of motorization, its small size, its easy maintenance.
  • Another advantage of the device according to the invention is that it does not include "FUSE" element on the stair nosing.
  • Another advantage of the device according to the invention is the synchronization of door movements and articulated step.
  • Figure 1 is a partial sectional side view of an access door 1 of a railway vehicle whose level 2 is equipped with an access device 3 to the vehicle 4 according to the invention.
  • the vehicle access device 3 4 is disposed under the fixed threshold 5 of the door access 1 and is in the retracted position.
  • the access device 3 to the vehicle 4 is articulated so as to retract under the effect of a horizontal thrust induced by the leaves 6 of door 1, at the end of the closing of these leaves 6 of door 1.
  • the access device 3 to the vehicle 4 automatically exits when the door leaves 6 1.
  • the access device 3 to the vehicle 4 comprises, in the space available under the fixed threshold 5 of the access door 1, a step 7 articulated at its lower end 0.
  • the articulated step 7 is thus capable of filling, in the extended position, with around 70% of the gap 8 between threshold 5 of access door 1 and platform 9.
  • Figure 2 corresponds to the partial sectional profile view of Figure 1 in which the vehicle access device is in the extended position.
  • Each of these control devices 10 is provided with a control arm 12, an intermediate arm 11 and an exit or re-entry arm 13 of the articulated step 7.
  • the control arm 12 is pivotally mounted at the end A of the fixed threshold 5 of the access door 1.
  • the exit or re-entry arm 13 of the articulated step 7 is mounted free in rotation, by one of its free ends B, on the articulated step 7 and is also freely mounted in rotation by the other of its ends C on the vehicle chassis rail.
  • the exit or re-entry arm 13 of the articulated step 7 comprises, by example, two articulated half arms, that is to say integral with each other and mounted free in rotation by their ends D facing each other.
  • the intermediate arm 11 is mounted to rotate freely at one of its ends on the ends D of the exit or re-entry arm 13 facing each other and is mounted at rotation by the other of its ends on one of the ends E of the control arm 12.
  • the control devices 10 with connecting rods or cams each comprise at minus a spring 14 ensuring the automation of the movements, and, more particularly, requests walking in the output state.
  • the springs 14 are held by their upper end G at a beam element fixed to the body of the vehicle 4 and are rotatably mounted by their other end H at the ends D of the exit or re-entry arm 13 facing each other.
  • the number of springs 14 and the forces exerted by these springs 14 are mainly dependent on the mass of the articulated step 7, friction and forces induced by the access device 3 on the leaves 6 of the door 1.
