    专利说明:

    The invention relates to a movable footboard for the doors of vehicles, in particular railway wagons, according to the preamble of claim 1.
    Railway wagons are understood in the description and claims to be rail vehicles for passenger transport, whether they are trams, subways, highways, suburban trains or passenger trains.
    There is often a problem with such vehicles in that when stopping in a station between the floor, actually the so-called tread, which represents the door-side end of the same, on the one hand and the platform on the other hand in the horizontal direction there is a gap and in many cases also a height difference. Various proposals have been made to provide bridging of this gap, either independently of opening the door or independently, but all of these attempts adhere to several disadvantages, including, for example, the vertical extension of the upper floor edge of the car and the adjacent upper edge of the footboard even after the extension of a step board.
    Another type of bridging consists of a so-called ramp, which is always extended by the same length, comes to rest with its front on the platform and is then raised with the wagon end until equal height is established. The major disadvantage is the dangers inherent in the Pushing over the platform and in some cases also in the contact area with the step arise.
    Lowering the treadle to the extended footboard has also been suggested, but because of the height of the treadle there is no real matching of levels, and here the risk of entrapment and fouling on the other hand is too great for general use even allow enforcement.
    It is the object and object of the invention to solve this problem or at least to reduce, thus creating an extendable footboard, in which the height difference between the floor top (tread bar) and the footboard is significantly reduced or eliminated in the extended and operational state, even with different extension distances.
    These objects are achieved by the measures and characteristics indicated in the characterizing part of claim 1; in other words, the footboard has on its surface walk-on elements that can be lifted and thus reduce or eliminate the height difference.
    The invention will be explained in more detail below with reference to the drawing, in which Fig. 1 shows an inventive footboard in a partially extended position, Fig. 2, the footboard in the raised position ready for use, Fig. 3 shows the situation of Fig. 2 in 4 shows a bottom view of a running board according to the invention, FIG. 5 shows a first variant of the lifting mechanism, FIGS. 6 and 7 variants of the lifting mechanism in views analogous to FIG. 5 in three different positions, FIG. 8 shows an embodiment 9 and 10 two details and Fig. 11 shows a further detail of the invention.
    A footboard designated in its entirety by 1 is arranged underneath a tread bar 2 einessonst car body not shown in the door area. The footboard 1 can be moved parallel to the Doppelpfeil3 in approximately horizontal direction transverse to the direction of travel. The shift occurs between a fully inserted position in which the footboard 1 does not protrude above the clearance space and an extended position in which the footboard 1 has come so close to a platform 4 as is technically possible. 1 shows an intermediate layer of the treadboard 1, clearly visible are the height differences between the upper floor edge 5, the surface 6 of the footboard 1 and the platform upper edge 7.
    FIG. 2 shows the situation in the ready state in a view similar to FIG. 1: the footboard 1 is extended in the direction of extension of the arrow 3 so far that as many as possible of its movable cross sections 8-12 can be raised in the manner shown. The mechanism by which lifting occurs will be explained below.
    From the illustrated position of FIG. 2 it can be seen that during further pushing out of the treadboard 1, only a part of the transverse profile 11 would emerge below the tread strip 2, so that it would not be possible to lift the transverse profile 11. For this reason, the ejector in the illustrated position may end up somewhat further in order to properly divide the residual gap 13 into two areas, depending on the governing philosophy of the operator, or the law or applicable standards.
    By raising the transverse profiles 8, 9 and 10 in the form of a pivoting movement, it is achieved that the accessible area formed by the transverse profiles continues without height offset in the area of the upper floor edge 5. This is important and valuable, in particular, for driving on this surface, for use with wheelchairs, baby carriages and the like.
    The remaining gap 13 is always smaller than the length of the transverse profiles in the direction of ejection and thus negligibly small compared to current solutions.
    Fig. 3 shows a variant of Fig. 2, in which the footboard 1 adjustable in height, preferably as shown pivotally mounted, whereby the difference in height14 between the end of the transverse profile 8 and the platform upper edge 7 can be reduced or eliminated. The horizontal line 15 makes this obvious.
    Fig. 4 shows a bottom view of the footboard 1, from which the construction proceeds well: at the free end of two longitudinal bars 17, about a longitudinal axis 16 at least approximately parallel to the direction of travel pivotally, the foremost transverse profile 8 is fixed. Below the transverse profile 8 protrudes a pair of pivoting bars 18 which are also pivotally mounted about the longitudinal axis 16, from the free edge 19 to the car body, the pivoting bars 18 are fixedly connected to the next transverse profile 9. The same is the case with a pair of further pivoting spars 20 and the transverse profile 10 and so forth (without reference numerals) to the last transverse profile 12. Of course, it is possible to provide only one pivoting spar or more than two in each case.
    Due to this construction, when one of the cross profiles 8 to 12 is raised beyond the configuration of the swivel bars 18 to 20 etc. from the free edge 19, each of the transverse profiles therebetween will now be raised while the further cart side thereof profiles will continue to rest on the longitudinal bars 17. FIG There are five cross profiles, it can be more or less, at least two are needed to be used wisely.
    This mode of operation becomes clear from a comparison with FIG. 5, which in its first representation shows a side view with all transverse profiles on the longitudinal members 17, the second representation shows a schematic section in which the formation of the transverse profiles 8 to 12 is clearly visible, and the third figure shows how the transverse profile 10 is raised by means of a rotary element 21 and by means of its pivoting spars 20 the transverse profiles 8 and 9, which are closer to the free edge 19 than the transverse profile 10, are pivoted about the pivot axis 16 and thus lifted.
    6 shows, purely diagrammatically, how the rotary element 21 is rotated via a linear drive 22 in such a way that it raises the transverse profile located in each case in its area, in the given case the transverse profile 10.
    It is clear that the rotary member 21, its storage and associated linear drive 22 Wagenwagenfest is arranged to raise each of the transverse profile, which is in the correct position with respect to the tread bar 2 and its front edge.
    9 shows a mechanism which is well suited for this movement: a linear drive 22 which can be moved back and forth linearly in the direction of extension has at its front end area a folding axis 28 which is essentially parallel to the longitudinal axis 16. Swiveling about this hinged axis 28 is an anti-clockwise rotating element 21 which moves along a guide member in the course of the pushing movement until it passes it and, due to the action of the torque, raises it.
    As the second illustration of FIG. 9 shows, the rotary element engages in the lifting part 27 of the assigned transverse profile 8-12 and lifts it up, as shown in more detail in FIG. 11.
    Fig. 10 shows a variant in which instead of the guide member 29, a guide rail 30 is arranged on the car body into which a bolt 31 of the rotary member 21 engages, actually, there are both sides of the rotary member provided guide elements. The rotary element 21 is in turn pivotally connected to the linear drive 22.
    Fig. 11 shows a useful embodiment of the connection between the rotary member 21 and the lifting member 27: A flattened pin 32 of the rotary member 21 whose angular position on the rotary member 21 correlates with its angular position at the moment of meshing abuts a catching surface 33 of the lifting member and becomes wider Moving the linear drive 22 (Fig. 9,10) pushed into a circular recess 34. When the bolt 32 reaches the end of the recess 34, the horizontal movement comes to an end and the bolt 32 moves in the sequence in the vertical direction, as a result of the rotation of the bolt comes to its positive locking in the recess 34.
    FIG. 7 shows a variant of FIG. 6 relating to the lifting mechanism, here a pure movement of a rotary element 21 is caused by a spreading movement of a spreader 23 by means of a linear drive 22. Again, the connection between the rotary member 21 and lifting member 27 as described above, take place.
    Fig. 8 shows, also purely schematically, a possibility for the reduction or elimination of the height difference 14 (Fig. 2) between the free end of the footboard and the platform upper edge: A guide 24 for the footboard 1 is in turn about a guide axis 25 which is parallel extends to the carriage longitudinal axis, pivotally mounted. With the help of a pivoting mechanism, such as a movable double wedge 26 or a linear actuator such as spindle, or hydraulic, or pneumatic, cylinder-piston unit, the guide 24 and thus the footboard 1 can be pivoted about the guide axis 25 and compensate for the height difference 14. The double arrow 26 indicates this movement, as it is limited, depends on the particular vehicle and the specifications of the railway administration.
    The invention is not limited to the illustrated and described embodiment, but may be variously modified. Thus, it is possible to arrange the lifting mechanism with the rotating element 21 or spreading element 23 not double and lateral edge of the footboard 1, but centrally and only simply, it can the division of the remaining horizontal gap 13 on the side of the platform 4 and on the side of Floor 2 may be made differently than shown, but this then requires an adjustment of the position or extent of lifting of the lifting mechanism, so as not to unintentionally create any, albeit small, height difference in the area of the floor top, because the point of application of the lifting mechanism with respect to the transverse profile will then vary with the remaining gap width changed.
    The design of the lifting mechanism may differ from the illustrated examples, it is possible to provide a fixed hydraulic or pneumatic piston-cylinder unit, which pushes the respective cross-sectional profile upwards purely by force, and the like more.
    As materials, materials and components, it is possible to use all those known in the art for sliding steps or folding steps, with knowledge of the invention and knowledge of the subject area and of the vehicle to be equipped, there are no problems for the person skilled in the art.
    In summary, it can thus be stated that the invention essentially relates to a movable footboard for a door of a vehicle, in particular a rail vehicle, with a footboard 1 which can be extended at least substantially transversely to the direction of travel underneath the tread strip 2. To improve the connection between footboard and tread is provided that at least one longitudinal spar 17 of the footboard 1 at least one longitudinal axis 17 of the footboard 1 is at least substantially parallel to the direction of pivot axis 16 is provided to pivot around at least two pivoting spars 18, 20 are mounted, each a Querprofil Wear 8-12. In this case, each of the swivel bars, as shown, be divided into zweiluchtende swivel bars to improve the mechanical and dynamic situation; Also, more than two such pivoting spars are usually provided in order to provide more than two transverse profiles 8-12 can. Furthermore, each of the swivel bars is firmly connected only to its associated transverse profile 8-9, while the other transverse profiles rest freely on it. Finally, a lifting mechanism 21,22,23 is provided vehicle-fixed, which raises only the located immediately in front of the tread bar 2 cross profile 8-12.
