Description

Die Erfindung bezieht sich auf einen Klapptritt für Schienenfahrzeuge nach dem Oberbegriff des Anspruchs 1.The invention relates to a folding step for rail vehicles according to the preamble of claim 1.

Bei Schienenfahrzeugen, insbesondere solchen mit tiefliegendem Fahrzeugboden und stark eingezogener Wagenschürze steht für den Klapptritt einschließlich der Trittmuldenabdeckung und des Antriebsgestänges nur eine sehr begrenzte Einbauhöhe und-tiefe zur Verfügung und dennoch muß die Trittstufe in der Einstiegsposition zur überbrückung des relativ großen Abstandes zwischen Fahrzeugwand und Bahnsteig weit über das Fahrzeugaußenprofil hinausreichen,um einen bequemen und gefahrlosen Einstieg zu gewährleisten. Wird außerdem die Trittmuldenabdeckung anstatt durch einen komplizierten Falt-und Schiebemechanismus.in baulich einfacher Weise als Ganzes um eine im Bereich der Fußboden-Auftrittskante angeordnete Drehachse nach unten in den Trittkasten geschwenkt, so ist man bei den bekannten Klapptritten (DE-OS 2 423 467, 2 245 085) darauf angewiesen, einen großen Teil des Trittkastenvolumens für die Schwenkbewegung der Trittmuldenabdeckung freizuhalten und die bewegliche Trittstufe im eingefahrenen Zustand außerhalb des eigentlichen Trittkastens entweder unterhalb desselben oder seitlich außen an der Wagenschürze in einer zu dieser parallelen, durch einen Dreh-Schiebemechanismus hochgekippten Lage anzuordnen, woraus sich neben aerodynamischen auch Probleme hinsichtlich der Verschmutzungs-und vor allem Vereisungsgefahr ergeben.In the case of rail vehicles, especially those with a low vehicle floor and a heavily retracted car apron, there is only a very limited installation height and depth available for the folding step, including the step recess cover and the drive linkage, and yet the step must be in the entry position to bridge the relatively large distance between the vehicle wall and the platform Reach far beyond the vehicle exterior profile to ensure a comfortable and safe entry. If, in addition to a complicated folding and sliding mechanism, the step trough cover is pivoted downwards in a structurally simple manner as a whole about an axis of rotation arranged in the area of the floor tread edge, 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.

Aufgabe der Erfindung ist es, einen Klapptritt nach dem Oberbegriff des Anspruchs 1 so auszubilden, daß er in der eingefahrenen Lage ein äußerst geringes Einbauvolumen benötigt und vollständig innerhalb eines räumlich beengten Trittkastens unterzubringen ist.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.

Diese Aufgabe wird erfindungsgemäß durch den im Anspruch 1 gekennzeichneten Klapptritt gelöst, bei dem der Schwenkbereich der Trittmuldenabdeckung als Stauraum für die bewegliche Trittstufe in der Weise ausgenutzt wird, daß diese im eingefahrenen Zustand unterhalb der Trittmuldenabdeckung angeordnet ist und beim Ausfahren in die Einstiegsposition zunehmend aus dem Schwenkbereich herausbewegt u n d- die Trittmuldenabdeckung gleichzeitig mit Hilfe eines entsprechenden kinematischen Steuergestänges ungehindert aus ihrer Schließ-in die die Trittmulde freigebende Schwenklage nach unten gedreht wird, was eine äußerst einfache und kompakte Bauweise garantiert und den erfindungsgemäßen Klapptritt insbesondere für moderne Reisezugwagen geeignet macht, die wegen des niedrigen Fußbodenniveaus und der stark eingezogenen Wagenschürze nur sehr kleine Trittkastenabmessungen zulassen und im allgemeinen einen weit über das Wagenprofil ausfahrbaren, einstufigen Klapptritt benötigen.This object is achieved by 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.

Eine weiter verbesserte Raumausnutzung des Trittkastens wird gemäß Anspruch 2 dadurch erreicht, daß die Trittstufe mit Hilfe eines Dreh-Schiebemechanismus aus der Einstiegsposition in eine Schräglage innerhalb des Trittkastens zurückgekippt wird, so daß sowohl die Höhe als auch die Tiefe des Trittkastens kleiner als die Auftrittsbreite der Trittstufe gehalten werden kann.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.

Eine weitere bauliche Vereinfachung wird gemäß den Ansprüchen 3 und 4 zweckmäßigerweise dadurch erreicht, daß die Trittmuldenabdeckung in der Einstiegsposition einen Abschlußsteg für die bewegliche Trittstufe bildet und diese gleichzeitig gegen ein Überkippen unter Last sichert. Gemäß Anspruch 5 schließlich erfolgt der Antrieb sowohl der Trittmuldenabdeckung als auch der Trittstufe durch eine einzige, gelenkfrei am Trittkasten befestigte Kolbenzylindereinheit und ein aus wenigen Einzelteilen bestehendes Steuergestänge, wodurch der Platzbedarf und der Bauaufwand des erfindungsgemäßen Klapptritts weiter deutlich verringert werden.A further structural simplification is expediently achieved according to claims 3 and 4 in that the 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. Finally, according to claim 5 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.

Die Erfindung wird nunmehr anhand eines Ausführungsbeispiels in Verbindung mit den Zeichnungen näher erläutert. Es zeigt:

  • Fig. 1 eine stark schematisierte Schnittdarstellung des Klapptritts im eingefahrenen Zustand; und
  • Fig. 2 den Klapptritt in der Einstiegsposition.
The invention will now be explained in more detail using an exemplary embodiment in conjunction with the drawings. It shows:
  • Figure 1 is a highly schematic sectional view of the folding step in the retracted state. and
  • Fig. 2 the folding step in the entry position.

Der einstufige Klapptritt 2 enthält eine auf der Oberseite mit dem Fußbodenbelag 4 beschichtete Trittmuldenabdeckung 6, die im hochgeklappten Zustand (Fig. 1) eine an den Fahrzeugboden 8 bündig anschließende, begehbare Trittflächenverlängerung bildet und die durch den Trittkasten 10 begrenzte Trittmulde 12 nach nach oben verschließt, so daß die Lücke zwischen der Fußboden-Auftrittskante 14 und der geschlossenen Schwenk-Schiebetür 16 des Fahrzeugs im wesentlichen spaltfrei überbrückt wird. Über beidseitig angeordnete, zur Fußboden-Auftrittskante 14 geringfügig versetzte Drehzapfen 18 ist die Trittmuldenabdeckung 6 um eine in Fahrzeuglängsrichtung verlaufende Drehachse über einen Schwenkbereich A von etwa 90° in eine vertikale Einstiegsposition (Fig. 2) nach unten schwenkbar gelagert, wobei der Antrieb durch eine z.B. pneumatische Kolben-Zylindereinheit 20 erfolgt, die starr an einer schmalen, in der Mitte zwischen den Seitenwangen 21 des Trittkastens 10 angeordneten Trittkasten-Verlängerung 22 befestigt und deren Kolbenstange 24 über eine Gelenkachse 26 und mehrere, in Fahrzeuglängsrichtung verteilte Zwischenlenker 28 und entsprechende Drehzapfen 30 antriebsschlüssig mit der Trittmuldenabdeckung 6 verbunden ist.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. 2), with the drive being supported by a For example, 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.

Die bewegliche Trittstufe 32 ist im eingefahrenen Zustand (Fig. 1) in eine Schräglage hochgekippt, in der sie unterhalb der Trittmuldenabdeckung 6 in deren Schwenkbereich A angeordnet ist und den Trittkasten 10 im wesentlichen diagonal in Richtung seiner, im Querschnitt gesehen, größten Längenabmessung durchsetzt, so daß die Trittstufe 32 sehr lang ausgebildet werden kann, um in der horizontalen Ein - stiegsposition (Fig. 2), in der sie sich auf einem annähernd mittleren Höhenniveau zwischen der Fußbodenoberkante und der Oberkante des Bahnsteigs B befindet, eine durchgehende, von der Trittmulde 12 unter Überbrückung des relativ großen Abstands zwischen stark eingezogener Wagenschürze 34 und Bahnsteigvorderkante über das Fahrzeugaußenprofil hinausreichende Trittfläche zu bilden und dadurch einen gefahrlosen Einstieg zu gewährleisten.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.

Die Steuerung der beweglichen Trittstufe 32, die auf ihrer Oberseite mit einem trittfesten Belag 36 versehen ist, zwischen ihrer vorgeschobenen, horizontalen Einstiegsposition und der zurückgezogenen und hochgekippten Einfahrstellung bewirkt ein insgesamt mit 38 bezeichneter Dreh-Schiebemechanismus, der eine gebogene Steuerkulisse in Form von an den Seitenwangen 21 des Trittkastens 10 befestigten U-Schienen 40, in denen die Trittstufe 32 überRollen 42 geführt ist, sowie einen Doppelhebel 44 enthält, der um eine in Wagenlängsrichtung verlaufende Drehachse 46 amTrittkasten 10 schwenkbar gelagert ist. Der eine, als Kniehebel ausgebildete Hebelarm 48 ist an der beweglichen Trittstufe 32 über einen Drehpunkt 50 angelenkt, der gegenüber den Führungsrollen 42 zum hinteren Trittstufenende hin versetzt angeordnet ist, so daß die Trittstufe 32 bei Drehung des Hebels 44 und unter Steuerung der Kulissenführung 40, 42 zwangsweise die erwähnte, kombinierte Dreh-Schiebebewegung ausführt. Angetrieben wird der zu Hebel 44 ebenfalls von der Kolben-Zylindereinheit 20, und diesem Zweck ist der zweite Hebelarm 52 des Doppelhebels 44 an die kolbenstangenseitige Gelenkachse 26 angeschlossen und enthält eine in Fig. 1 schematisch gezeigte, in Hebellängsrichtung wirkende Teleskopverbindung 54, die die zwischen den Drehpunkten 26 und 46 beim Kolbenstangenhub auftretenden Abstandsänderungen ausgleicht.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.

Der Dreh-Schiebemechanismus 38 und insbesondere dessen Kulissenführung 40 sind so ausgebildet, daß die Trittstufe 32 beim Ausfahren in der Anfangsphase eine verstärkte Drehbewegung vollführt, so daß die Trittmuldenabdeckung 6 synchron zur Ausfahrbewegung der Trittstufe 32 ungestört über den Schwenkbereich A nach unten in die Einstiegsposition verschwenken kann, in der ihre Stirnkante dicht über dem hinteren Endabschnitt der Trittstufe 32 liegt (Fig. 2), so daß sie einen vertikalen Trittstufen-Abschlußsteg sowie eine zusätzliche Sicherung gegen ein Überkippen der Trittstufe 32 unter Last bildet.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.

Die Trittmuldenabdeckung 6 und vor allem die Trittstufe 32 können durch nichtgezeigte Federn in die Fahrtstellung (Fig.1) vorgespannt sein, um störende Vibrations-und Geräuscherscheinungen während der Fahrt zu unterbinden, und werden in ihren Endpositionen durch ebenfalls nicht gezeigte, trittkastenfeste Anschläge begrenzt. Eine dem Antriebszylinder 20 zugeordnete elektro-pneumatische Steuerung stellt, ausgelöst durch Endschaltertsicher, daß der Klapptritt 2 erst bei voll geöffneter Tür 16 ausgefahren und vor dem Schließen der Tür 16 wieder vollständig in die Fahrtstellung zurückgebracht wird.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.
