Definitions

  • the present invention relates generally to self-supported steps. Specifically the present invention relates to movement of a step between a first retracted position and a second extended position for alighting and boarding from a railway car or the like .
  • Ramps are sometimes used at railway cars for alighting and boarding.
  • a ramp needs support from a platform to hold the ramp during such alighting and boarding.
  • DE 4134559 describes such a ramp, which needs support from a platform. It is, however, desirable not to be dependent of a platform as support since different railway stations have differently elevated platforms.
  • a problem with movable steps is that links or stays above the step occupy the same space that doors occupy when the floor level of a railway car and the floor level of a movable step are close to each other.
  • One object of the present invention is to provide an arrangement that increases the space above a movable self- supporting step.
  • Another object of the present invention is to provide an arrangement that reduces the risk of crushing injuries when a step is moved between its retracted and extended positions .
  • An advantage with the present invention is that it increases the available space above an extended step.
  • Another advantage with the present invention is that it reduces the risk for crushing injuries during use of a movable step.
  • Fig. 1 shows a side view of a movable step in retracted position
  • Fig. 2 shows a side view of the movable step shown in Fig. 1 in extended position
  • Fig. 3 shows a side view of the movable step shown in Fig. 1, where an obstacle interrupt movement of the movable step;
  • Fig. 4 shows a side view of the movable step shown in Fig. 2 with a cutaway portion.
  • An arrangement for movement of a self-supported step 1 between a first retracted position and a second extended position at a railway car or the like comprises: a lever arm 2 and a swivel arm 8 at each side of the step 1 and a pivoting device 9 mounted at the railway car between the swivel arms .
  • the arrangement will be described regarding one side of the step 1, since the opposite side of the step 1 is eguivalently designed.
  • the lever arm 2 is in one point 14 close to a first end thereof jointly attached to a plate 6 and to the step 1.
  • the lever arm 2 is in another point 16 close to the other end thereof jointly attached to the railway car.
  • the lever arm 2 has a stopper 3 arranged between the points 14 and 16, and a sealing tip 5 arranged in the extension of the lever arm 2.
  • the stopper 3 comprises an essentially flat side substantially perpendicular to the longitudinal direction of the lever arm 2.
  • the sealing tip 5 is arranged to protect the pivoting device 9 against dirt when the step 1 is in its retracted
  • the swivel arm 8 is in one point 13 close to one end thereof jointly attached to the step 1 and to the plate 6, and in another point 15 close to the other end thereof attached to the pivoting device 9.
  • the distance between the attachment points 13 and 15 of the swivel arm 8 differs from the distance between the attachment points 14 and 16 of the lever arm 2, such as to provide a desired movement of the step.
  • the swivel arm 8 has a locking device 7 arranged in its longitudinal direction.
  • the locking device 7 comprises an essentially flat side substantially perpendicular to the longitudinal direction of the swivel arm 8, arranged to lock to the stopper 3 when the step 1 is in extended position.
  • the attachment points 13-16 of the lever arm 2 and the swivel arm 8 form a triangular shape when the step 1 is in extended position.
  • the attachment point 13 of the swivel arm 8 is apart from the attachment point 14 of the lever arm 2, in the step 1.
  • the plate 6 connects the lever arm 2 and the swivel arm 8 to enhance the stability of the arrangement. Since both the step 1 and to the plate 6, the step 1 is predictably moved between its retracted and extended positions .
  • the step 1 When the step 1 is in its retracted position, as illustrated in Fig. 1, it is arranged integrated with the profile of the side of the railway car.
  • the pivoting device 9 revolves the swivel arm 8 out from the side of the railway car.
  • the step 1 is therewith lifted upwards until the locking device 7 is positioned at the stopper 3, and the step 1 is in its extended position, as illustrated in Fig. 2.
  • This movement is e.g. performed by means of that the pivoting device 9 revolves the swivel arm 8 to a predetermined position, see Fig. 2, where the locking device 7 is at the stopper 3.
  • the stopper 3 and the locking device 7 keeps the step 1 in its extended position by means of mutual locking of the swivel arm 8 and the lever arm 2.
  • the locking of the step 1 in extended position may also be performed by locking the pivoting device, but this is a less preferred solution.
  • the step 1 When the step 1 is in its extended position, as illustrated in Fig. 2, it is positioned essentially at the same elevation level as a landing 10 of the railway car.
  • the whole arrangement, that is used to extend/retract the step 1, is completely below this elevation level, and therewith no parts exist above this elevation level where there is a risk of crushing injuries.
  • the pivoting device 9 is arranged to revolve the swivel arm 8 back, towards the railway car, to the retracted position illustrated in Fig. 1.
  • the pivoting device 9 is run by an electrical motor, which that control the extension/retraction of the step 1, i.e. to predetermined positions. Activation of the extension/retraction of the step 1 may be performed in several different ways. Opening/closing of a door above the step 1 may activate extension/retraction of the step. Buttons at the outside and/or inside of the railway car may extend/retract the step 1. Buttons at the engine driver or wireless remote control are other alternatives that may be used.
  • the second embodiment of the present invention comprises all features described in the first embodiment.
  • the step 1 is a stand alone unit attached to a support structure in which the lever arms 8 and the swivel arms 2 are attached to as described above.
  • the step 1 is arranged to allow a small movement relative the support structure.
  • the arrangement comprises detectors that detect positions of the step 1 relative the support structure.
  • a movement of the step is interrupted.
  • interruptions may be: Detection of an obstacle 17 on the platform obstructing the extension of the step 1, induces the step to be retracted.
  • a weight on the step such as a person alighting/boarding the railway car, interrupt retraction of the step 1.
  • the platform is very close to the railway car the step 1 is kept in retracted position, since there is no gap to bridge between the railway car and the platform.
  • the design of the arrangement is illustrated in Fig. 4 with the plate 6 cutaway.

Abstract

La présente invention concerne un système de déplacement d'un marche-pied autoporté (1) d'un véhicule ferroviaire ou équivalent. Ce marche-pied est mobile entre une première position pliée et une deuxième position déployée. La hauteur de la partie du marche-pied la plus proche du véhicule ferroviaire ou équivalent est positionnée sensiblement à la même hauteur qu'un palier du véhicule ferroviaire ou équivalent lorsque ce marchepied est en position déployée. Ce système comprend: un bras oscillant (8), par sa première extrémité (13), de façon mobile au marchepied et fixé, par sa deuxième extrémité (15), à un dispositif de pivotement (9) qui est attaché au véhicule ferroviaire ou équivalent. Un bras de levier (2) mobile est fixé, par sa première extrémité (14), au marchepied et, par sa deuxième extrémité (16), de façon mobile au véhicule ferroviaire ou équivalent. Le bras oscillant est fixé, séparément du bras de levier, au marchepied et ce système auto-porté est entièrement situé sous la hauteur du palier.
