    description
    gap filling
    Technical area
    The invention relates to a gap bridging for a rail vehicle for bridging the gap between a passenger compartment floor and a platform.
    State of the art
    Gap bridging is used in modern rail vehicles to allow passengers a comfortable entry and exit and in particular to minimize the risk of the gap between the passenger compartment floor and the platform. This gap has a width of about 100 mm in typical subway lines, but can also be up to 300 mm, for example, for platforms in a curve. This variance of the gap dimensions represents a particular source of danger, since the passengers would have to be aware of each time they get on or off the current platform gap, which is often not possible, especially when there is a high passenger volume. For bridging this platform gap Spaltunbrückungen can be used, which usually include a sliding plate mounted, which is powered by the vehicle pushed out. For larger gap width, this plate and its storage are very solid, so that the space requirement increases and thus such gap bridging can only be very complicated and provided under impairment of the car body in the door area. With so-called folding / Schiebetritten this problem can be partially solved because such a pivotally mounted lever supports the plate from below and thus significantly reduces the forces on the storage of the plate. Therefore, such folding / sliding steps require less space and can be used in the entry area of a passenger rail vehicle without changes to the car body structure, at the installation position of this gap bridging simply removed the conventional floor construction and replaced by the gap bridging. However, the kinematics of this Spaltüberbrückungen in the form of a folding / Schiebetritts requires that at far extended plate this lowers at its platform edge and thus creates a step to the platform. In addition, a widely extended plate on a steep slope in the direction of the car interior. These properties make gap bridging in the form of a folding / sliding step unsuitable for larger platform gaps.
    Presentation of the invention
    The invention is therefore based on the object to provide a gap bridging in the form of a folding / sliding step, which is suitable for larger platform gaps and in which in particular the difference in height between a platform and the platform side edge of the footboard is minimized at large extension distances.
    The object is achieved by a gap bridging with the features of claim 1. Advantageous embodiments are the subject of the subordinate claims.
    According to the basic idea of the invention, a gap bridging for a rail vehicle for bridging the gap between a passenger compartment floor and a platform is described which comprises a horizontally slidably mounted step plate and a pivot arm, which can be pivoted about a rotation axis arranged below the step plate parallel to the vehicle longitudinal axis, extending from the axis of rotation extends to the tread plate extends, wherein the pivot arm is pivotally connected to the tread plate and is slidably mounted on the tread plate over a certain length portion, and wherein a restoring force acts in a rest position on the pivot arm.
    Thus, the advantage of being able to build a gap bridging in the form of a folding / sliding step, which is suitable for large extension distances, since the platform side edge of the footboard is held in its movement substantially at the same height and the drop of the platform edge, as in conventional gap bridging prevented or greatly reduced.
    According to the invention, the kinematics of a gap bridging in the form of a folding / sliding step is designed so that the articulation point (joint) of the pivot arm is designed on the tread plate as a sliding pivot, so that the pivot arm can perform both in rotation to the tread plate, as well as the fulcrum is freely movable in a certain area.
    In such a way, the articulation point of the swivel arm can be displaced in the direction of the rail vehicle with the foot plate pushed far out, so that a support of the footboard closer to the carriage takes place. As a result, the platform-side edge of the tread plate decreases in comparison to conventional
    Gap bridging from significantly lower, which reduces both the difference in level between the platform side edge of the tread plate and the platform and the ramp angle of the tread plate, or repeals. With suitable dimensioning of the components, a gap bridging according to the invention can achieve a smooth transition from a platform to a tread plate even with large bridging widths.
    The articulation point (pivot point, joint) of the pivot arm on the tread plate is slidably mounted in a certain length section, preferably between the platform side end of the tread plate and a stop. The exact dimensioning of the required length section is based on the given geometry of a gap bridging and the required extension of the tread plate.
    It is essential that the entire sequence of movements in a retraction and extension of a tread plate and the associated pivoting movement of the pivot arm is effected only by means of a power drive, the pivot arm itself needs no drive, since he by the extension and retraction of the tread plate each in the required position is brought.
    In this case, the pivot arm is to be acted upon by a restoring force, preferably by means of a spring element which tries to move the pivot arm in its rest position (retracted tread plate). This restoring force causes the pivot arm retains the required position in relation to the tread plate when the tread plate is extended.
    The tread plate is mounted horizontally slidably, and preferably equipped with a power drive, by means of which it is displaceable between a rest position (retracted) and any number of extended positions. In this way, the optimal extension distance can be provided for different structural conditions within a railway track. Typically, an extension of the treadplate takes place until either the maximum extension distance is reached or the treadplate collides with the platform, the power drive being thereby switched off. In this case, the tread plate is mounted in a sliding guide, wherein the carriage-side end of the tread plate is guided and the platform side end is free to move, so that it can be supported by the pivot arm. In this case, the swivel arm transmits the majority of the weight forces acting on the tread plate and the sliding guide can thus be made very compact.
    In this way, the advantage can be achieved that a gap bridging according to the invention can be made so flat that it has the same thickness as a surrounding floor structure. Thus, a gap bridging without changes to the car body structure, in particular the door sill-side side members are installed.
    In a further development of the invention, it is advisable to equip the gap bridging with a device for preventing the ingress of dirt (scraper). In this case, a cover plate is provided above the tread plate in the passenger compartment floor, said cover plate is provided at its platform edge edge with a scraper. This cover plate has substantially the same height level as the vehicle floor surrounding it, so that inside the car no level differences caused by the gap bridging, in particular no steps are required. At the platform edge of this cover plate a scraper is to be arranged, which closes the platform-side gap between the cover plate and the foot plate during retraction of the footboard or substantially reduced, so that foreign bodies, or penetrate only up to a certain size in the space under the cover plate can.
    The scraper may be made of metal or a composite material and is hinged to the cover plate. For this purpose, either a hinge joint at the junction of the scraper with the cover plate is to be arranged or the scraper is firmly connected to the cover plate and has an integrated in him elastomeric joint. Depending on the embodiment of the scraper weight may be sufficient as a pressing force on the tread plate, but it is particularly advantageous to increase it by means of a spring force. As a result, the dirt retention capacity is significantly improved.
    In a further development of the invention, the scraper can be equipped with a brush, whereby the cleaning effect is further increased.
    In order to reduce the friction between the wiper and the tread plate, it is advantageous to provide the contact of the wiper with the tread plate at friction-disabled contact positions. The treadboard itself is to be provided with a slip-resistant surface, so that these friction-reduced contact positions may occupy only a small proportion of the accessible surface of the tread plate and should not even be accessible. It is therefore recommended that the friction-reduced areas in
    To arrange depressions of the accessible surface of the tread plate. The wiper is to be provided at the corresponding positions with suitable counterparts over which the friction-reduced areas can slide. It is particularly advantageous to equip the friction-reduced areas with a coating made of plastic, for example polytetrafluoroethylene.

    Embodiment of the invention
    Fig.l shows an example and schematically a gap bridging according to the prior art in the retracted position. A cross section through a passenger rail vehicle in the region of an exit is shown, wherein a gap bridging 1 'according to the prior art is provided. The passenger rail vehicle is shown in the form of its car body 12 comprising a side rail and a floor structure comprising a floor 13 and a cover plate 2. Between the vehicle and one
    Platform 3 is a gap 4 which is to be bridged by the gap bridging device 1 '. This comprises a tread plate 6 'according to the prior art, which is mounted horizontally slidably at its end of the cart box side by means of a sliding bearing 8. The tread plate 6 'is supported from below by a pivot arm 5' according to the prior art, which is pivotally mounted about an axis of rotation 7. At the end facing away from the axis of rotation 7, the pivot arm 5 'is connected via a hinge 10 to the tread plate 6', this joint 10 is fixedly arranged on the tread plate 6 '. The pivot arm 5 'is acted upon by a restoring force, which tries to retract it to its rest position, this is exemplified in Fig. 1, a spring 11 is shown. Fig. 1 shows the retracted state of the gap bridging 1 'as it is used in particular while driving. A force acting on the tread plate 6 'power drive is not shown for simplicity of illustration.
    2 shows an example and schematically a gap bridging according to the prior art in the extended position. It is the gap bridging 1 'from Fig.l shown, wherein the tread plate 6' is pushed into its most extended position and the gap 4 is thus bridged. In this position, a large difference in level between the platform 3 and the platform side end of the tread plate 6 'and the inclination of the tread plate 6' is particularly large.
    3 shows an example and schematically a gap bridging in the retracted position. It is a gap bridging 1 according to the invention in a cross section through a passenger rail vehicle, very similar to FIG
    Fig.l shown. The structure of the passenger rail vehicle is identical to the embodiment shown in Figs. 1 and 2, but the gap bridging 1 differs in the embodiment of the tread plate 6 and the pivot arm fifth
    The pivot arm 5 is pivotally mounted about an axis of rotation 7 and extends to the bottom of the tread plate 6, where the pivot arm 5 is mounted by means of a slider 9 on the tread plate 6 slidably. This slider 9 allows a rotational movement of the pivot arm 5 with respect to the tread plate 6 and in addition a displacement over a certain length along the tread plate 6. This length is wagenkastenseitig limited by a stop 14 and extends between the stop 14 and the platform end of the tread plate 6th
    4 shows an example and schematically a
    Gap bridging in half extended position. It is the gap bridging 1 shown in Figure 3, wherein the tread plate 6, the gap 4 partially bridged. This represents an intermediate stage, as it occurs during the extension to the largest extension or smaller columns 4. In this intermediate position, the pivot arm 5 is still in its rest position, in which it is held by the restoring force of the spring 11. The tread plate 6 is pushed over the slider 9, so that the stop 14 of the tread plate 6 rests against the slider 9.
    5 shows an example and schematically a
    Gap bridging in fully extended position. It is the gap bridging 1 shown in Figure 4, wherein the tread plate 6 is located in its widest possible extended position. The gap 4 is completely bridged and the difference in level between the platform 3 and the platform side edge of the tread plate 6 is very low.
    The pivot arm 5 supports the tread plate 6 at the innermost position of the longitudinal section over which the slider 9 can move, which is predetermined by the stop 14.
    6 shows an example and schematically a
    Gap bridging with scraper. It is similar to Figure 5 shows a gap bridging 1 in the fully extended position, wherein the tread plate 6 is located in its widest possible extended position. Furthermore, the embodiment shown in Figure 6 comprises a scraper 15 which is arranged on the platform side edge of the cover plate 2 and is pivotally connected to the cover plate 2 by means of a hinge 16. The joint 16 may be equipped with an elastic device which increases the pressing force of the scraper 15 on the tread plate 2. In this case, an edge of the scraper 15 touches the tread plate 6, whereby on the tread plate 6 adhering dirt is removed from the scraper 15 and thus this can not penetrate into the space below the cover plate 2. In this way, excessive contamination of the sliding bearing 8 and associated drive components can be prevented.
    Figure 7 shows an example and schematically a gap bridging with scraper in a floor plan. It is a view from above of a gap bridging 1 in its installation situation in a car body 12 shown. From the car body 12 cuts through two door pillars and parts of the outer wall are visible in this view. The tread plate 6 is located partially extended position, their surface is in areas with slip-resistant surface or
    Pad 18 and sliding surfaces 17 divided, wherein the sliding surfaces 17 occupy a much smaller proportion of the total surface. The sliding surfaces 17 are advantageously arranged lower than the surfaces 18 with slip-resistant coating so that they are not directly accessible. A scraper 15 is, as shown in Figure 6, hingedly connected to the cover plate 2.
