Definitions

  • the invention relates to a folding step for rail vehicles according to the preamble of claim 1.
  • the known folding steps (DE-OS 2 423 467 , 2 245 085) rely on keeping a large part of the volume of the step box free for the swiveling movement of the step recess cover and the movable step in the retracted state outside the actual step box either below it or on the outside of the side of the car apron in a parallel to it, by means of a rotary and sliding mechanism to arrange upturned position, which in addition to aerodynamic problems also arise with regard to the risk of contamination and, above all, icing.
  • the object of the invention is to design a folding step according to the preamble of claim 1 so that it requires an extremely small installation volume in the retracted position and must be accommodated completely within a confined kick box.
  • the folding step characterized in claim 1 in which the swivel range of the step cover is used as storage space for the movable step in such a way that it is arranged below the step cover in the retracted state and increasingly when moving out into the entry position from the Moved out swivel range and the trough cover at the same time with the help of a corresponding kinematic control linkage freely rotated downwards from its closing position into the swiveling position that releases the tread recess, which guarantees an extremely simple and compact design and makes the folding step according to the invention particularly suitable for modern passenger coaches due to the low floor level and the heavily retracted car apron, allow only very small step box dimensions and generally require a single-stage folding step that can be extended far beyond the car profile.
  • a further improved space utilization of the step box is achieved according to claim 2 in that the step is tilted back from the entry position into an inclined position within the step box with the aid of a rotary / sliding mechanism, so that both the height and the depth of the step box are smaller than the tread width of the Step can be held.
  • step trough cover forms a closing web for the movable step in the entry position and at the same time secures it against tipping over under load.
  • the drive follows both the step recess cover and the step by means of a single piston-cylinder unit fastened to the step box without joints and a control linkage consisting of a few individual parts, which further significantly reduces the space requirement and the construction costs of the folding step according to the invention.
  • the single-stage folding step 2 contains a step recess cover 6 coated on the upper side with the floor covering 4, which in the folded-up state (FIG. 1) forms a walkable step extension that adjoins the vehicle floor 8 and closes the step recess 12 that is delimited by the step box 10 , so that the gap between the tread edge 14 and the closed pivoting sliding door 16 of the vehicle is bridged essentially without a gap.
  • the trough cover 6 is pivoted downward about a pivot axis A running in the longitudinal direction of the vehicle over a pivoting range A of approximately 90 ° into a vertical entry position (FIG.
  • pneumatic piston-cylinder unit 20 takes place, which is rigidly attached to a narrow step box extension 22 arranged in the middle between the side walls 21 of the step box 10 and the piston rod 24 thereof via a joint axis 26 and a plurality of intermediate links 28 distributed in the longitudinal direction of the vehicle and corresponding pivot 30 is drivingly connected to the step cover 6.
  • the movable step 32 In the retracted state (FIG. 1), the movable step 32 is tilted up into an inclined position in which it is arranged below the step recess cover 6 in its swiveling area A and passes through the step box 10 essentially diagonally in the direction of its greatest length dimension, as seen in cross section, so that the step 32 can be made very long so that in the horizontal boarding position (FIG. 2), in which it is located at an approximately medium height level between the upper edge of the floor and the upper edge of the platform B, a continuous, from the step trough 12, by bridging the relatively large distance between the heavily retracted car apron 34 and the platform front edge, to form a step surface that extends beyond the vehicle outer profile and thus to ensure a safe entry.
  • the control of the movable step 32 which is provided on its upper side with a non-slip covering 36, between its advanced, horizontal entry position and the retracted and tilted retracted position results in a rotary and sliding mechanism, designated overall by 38, which has a curved control link in the form of the Sidewalls 21 of the step box 10 fastened U-rails 40, in which the step 32 is guided over rollers 42, and contains a double lever 44 which is pivotally mounted on the step box 10 about an axis of rotation 46 running in the longitudinal direction of the carriage.
  • One, designed as a toggle lever arm 48 is articulated on the movable step 32 via a pivot point 50, which is offset from the guide rollers 42 to the rear step end, so that the step 32 when rotating of the lever 44 and under the control of the link guide 40, 42 forcibly executes the aforementioned combined rotary / sliding movement.
  • the lever 44 is also driven by the piston-cylinder unit 20, and for this purpose the second lever arm 52 of the double lever 44 is connected to the articulation axis 26 on the piston rod side and contains a telescopic connection 54, shown schematically in FIG the pivot points 26 and 46 compensates for changes in distance occurring during the piston rod stroke.
  • the rotary-slide mechanism 38 and in particular its link guide 40 are designed so that the step 32 performs an increased rotary movement when extending in the initial phase, so that the trough cover 6 swivels undisturbed in synchronism with the extending movement of the step 32 via the pivoting range A down to the entry position can, in which its front edge lies just above the rear end portion of the step 32 (Fig. 2), so that it forms a vertical step end web and an additional safeguard against tipping over the step 32 under load.
  • the trough cover 6 and, in particular, the step 32 can be biased into the driving position (FIG. 1) by springs, not shown, in order to prevent disturbing vibrations and noise phenomena while driving, and are limited in their end positions by stops, also not shown, which are fixed to the kick box.
  • An electro-pneumatic control assigned to the drive cylinder 20, triggered by limit switch t, ensures that the folding step 2 is only extended when the door 16 is fully open and is brought back fully into the driving position before the door 16 is closed.
