Hierzu geht von der Zungenschiene eine zu einer Drehachse führende Stellstange aus, von der ihrerseits zwei symmetrisch zueinander angeordnete Halte- und Führungselementanordnungen ausgehen, die jeweils um eine ortsfeste Achse verschwenkbar sind. Dabei wirkt auf das Halteelement eine Federkraft derart, dass die Führungs-/Halteelementanordnungen aufgrund der einwirkenden Federkraft stets eine von zwei stationären Positionen einnehmen müssen, die jeweils einer der Endstellungen der Zungenschiene entsprechen. In der jeweiligen Endstellung befindet sich dabei die Drehachse, von der die Stellstange ausgeht, auf gegenüberliegenden Seiten einer die ortsfesten Achsen der Führungs-/Halteelementanordnungen verbindenden Gerade. Dies bedeutet, dass ein häufig nicht gewünschter Platzbedarf erforderlich ist.

Zum Umstellen der Zungenweiche wird ein Stellhebel um eine erste Achse verschwenkt, von der eine Pleuelstange ausgeht, die mit einem Winkelhebel verbunden ist, auf den seiner-seits eine zu der Zungenschiene führendes Stellglied angelenkt ist. Die erste Achse verläuft senkrecht zu den Schwenkachsen des Winkelhebels und des Stellgliedes. An dem Anlenkpunkt zwischen Winkelhebel und dem Stellglied greift ein um eine ortsfeste Achse verschwenkbares federvorgespanntes Halteelement an.A changeover device for points can be found in FR A 2 387 833. To the To change the tongue diverter, a lever is pivoted about a first axis, from which emanates a connecting rod, which is connected to an angle lever on his part an actuator leading to the tongue rail is articulated.

Der vorliegenden Erfindung liegt das Problem zu Grunde, eine Anordnung der eingangs genannten Art zur Verfügung zu stellen, die bei kompaktem und konstruktiv wartungsarmen Aufbau sicherstellt, dass eine bewegliche Schiene wie Zungenschiene sicher in ihren Endstellungen gehalten wird, wobei gleichzeitig eine Überprüfung erfolgen soll. Dabei soll ungeachtet der zur Endlagenfixierung erforderlichen Federkräfte sichergestellt sein, dass beim Verstellen der ersten Schiene nicht unerwünscht hohe Stellkräfte zum Überwinden der Federkräfte aufgebracht werden müssen.The present invention is based on the problem, an arrangement of the above mentioned type to provide the case of a compact and structurally low maintenance Construction ensures that a moving rail such as tongue rail is secure in their final positions, with simultaneous review. This is to ensure regardless of the spring forces required for end position fixation be that when adjusting the first rail not undesirably high actuating forces for Overcoming the spring forces must be applied.

Erfindungsgemäß wird das Problem im Wesentlichen dadurch gelöst, dass ortsfest zu der ortsfesten ersten Achse des Führungs- und Halteelementes ein Hebelelement um eine zweite Achse schwenkbar gelagert ist, das mit dem Halteelement verbunden ist und mit dem zumindest einen von der verstellbaren ersten Schiene ausgehenden Mitnahmeelement derart wechselwirkt, dass in der jeweiligen Endstellung der ersten Schiene das Halteelement derart kraftbeaufschlagt ist, dass die jeweilige Endlagenstellung unterstützt und überprüfbar ist, wobei das Hebelelement mit dem Halteelement über ein gelenkig mit dem Hebelelement verbundenes Gelenkelement über eine dritte Achse gelenkig verbunden ist, die parallel zu der ersten und zweiten Achse verläuft.According to the invention, the problem is essentially solved by being stationary the fixed first axis of the guide and holding element to a lever element a second axis is pivotally mounted, which is connected to the holding element and with the at least one of the adjustable first rail outgoing carrier element interacts such that in the respective end position of the first rail the Retaining element is subjected to such a force that supports the respective end position and verifiable, wherein the lever element with the holding element via a hinged connected to the lever element articulated element via a third axis articulated is parallel to the first and second axes.

Erfindungsgemäß wird eine Anordnung vorgeschlagen, mit der die erste Schiene wie Zungenschiene in ihrer jeweiligen Endstellung zusätzlich über das auf das Halteelement einwirkende Federelement fixiert wird. Hierzu geht von der Schiene das Mitnahmeelement aus, das über das Hebelelement bzw. dem mit diesem gelenkig verbundenen Gelenkelement mit dem Halteelement derart zusammenwirkt, dass bei Vorliegen einer der Endstellungen die Federkraft auf das Mitnahmeelement derart einwirkt, dass dieses und damit die erste Schiene fixiert ist. Dabei ist insbesondere die von dem auf das Halteelement einwirkende Federelement hervorgerufene Kraft stets derart gerichtet, dass das Hebelelement bestrebt ist, mit dem Mitnahmeelement derart zusammenzuwirken, dass die zu erreichende Endstellung der ersten Schiene bei dessen Bewegung unterstützt wird, und zwar insbesondere im letzten Drittel der Stellbewegung.According to the invention an arrangement is proposed, with the first rail as Tongue rail in their respective end position additionally on the holding element acting spring element is fixed.

It is especially the on the Holding element acting spring element always directed directed such that the lever element endeavors to cooperate with the entrainment element in such a way that that the end position to be reached supports the first rail during its movement especially in the last third of the actuating movement.

Ferner sollte dem Mitnahmeelement ein Schaltelement derart zugeordnet sein, dass dessen Betätiger in Abhängigkeit von der Stellung des Mitnahmeelementes Schaltsignale erzeugt, und zwar dann, wenn sich die erste Schiene in einer ihrer Endlagen befindet. Insbesondere sind dem Mitnahmeelement zwei Schaltelemente wie Schnappschalter zugeordnet, dessen jeweiliger Betätiger dann in eine in dem Mitnahmeelement vorhandene Ausnehmung eingreift, wenn sich die erste Schiene wie Zungenschiene in einer ihrer Endstellungen befindet. Hierdurch ist eine Überprüfung der Schienenstellung dahingehend möglich, dass sowohl die Endstellungen als auch die Zwischenpositionen auf den von den Schaltelementen abgeleiteten Signalen überprüfbar ist. Da das Schaltelement bzw. die Schaltelemente unmittelbar mit dem Mitnahmeelement, das wiederum mit der verstellbaren Schiene verbunden ist, zusammenwirkt, ergibt sich eine kompakte Bauweise derart, dass die Gesamtanordnung einschließlich der Schalter innerhalb eines Schwellenfeldes positionierbar sind, so dass die ansonsten zusätzlich notwendigen Lagereisen außerhalb der Schwellen, an denen Endlagenprüfer befestigt sind, die ihrerseits über Prüferstangen mit Zungenschienen verbunden sind, entfallen können.Furthermore, the driving element should be assigned a switching element such that whose actuator in response to the position of the driving element switching signals produced, and that when the first rail is in one of its end positions.

Auch besteht die Möglichkeit, sonstige durch die Bewegung der ersten Schiene mitbewegten bzw. mitverstellten Elemente der Anordnung zum Auslösen eines Signals wie Schaltsignals zu verwenden bzw. entsprechend auszubilden.Alternatively, the holding element and the switching element form a unit or press the latter. There is also the possibility of other by the movement of the first rail co-moving or mitverstellten elements of the arrangement for triggering a signal such as switching signal to use or form accordingly.

Insbesondere zeichnet sich die Erfindung dadurch aus, dass von der verstellbaren ersten Schiene zwei Mitnahmeelemente ausgehen, wobei jeweils in einer Endstellung der ersten Schiene eines der Mitnahmeelemente mit dem Hebelelement derart wechselwirkt, dass das Mitnahmeelement positionsgesichert ist, wobei zuvor eine Bewegungsunterstützung erfolgt.In particular, the invention is characterized in that of the adjustable first Rail two driving elements go out, each in an end position of the first Rail one of the driving elements interacts with the lever element such that the entrainment element is secured in position, previously having a movement support he follows.

Bei dem Hebelelement handelt es sich vorzugsweise um ein zweiarmiges Element, wobei auf gegenüberliegenden Seiten seiner Drehachse jeweils ein an jeweils einem Mitnahmeelement entlanggleitendes Gleitelement wie Rolle vorgesehen ist. Insbesondere sind die entsprechenden Gleitelemente am jeweiligen Ende eines geraden Schenkels bzw. Schenkelabschnitts angeordnet, der in einen abgewinkelten Abschnitt übergeht, an dem das zu dem Halteelement führende Gelenkelement angelenkt ist.The lever element is preferably a two-armed element, wherein on opposite sides of its axis of rotation in each case one at each one Carrier element sliding along sliding element such as roller is provided. In particular are the corresponding sliding elements at the respective end of a straight leg or Leg portion arranged, which merges into an angled portion on which which is articulated to the holding element leading hinge element.

Dabei ist das Mitnahmeelement derart ausgebildet bzw. das Gleitelement auf dieses derart ausgerichtet, dass bei jeweils in einer der Endstellungen befindlichen ersten Schiene eines der Gleitelemente mit einem der Mitnahmeelemente wechselwirkt und das andere Gleitelement in Ausgriff mit dem anderen Mitnahmeelement ist. Hierdurch kann durch die Verbindung mit dem Halteelement ein gezieltes Verschwenken des Hebelelementes derart erfolgen, dass dieses auf das mit diesem wechselwirkende Mitnahmeelement derart einwirkt, dass eine Unterstützung dessen Verstellung insoweit erfolgt, dass die mit dem Mitnahmeelement verbundene Schiene in ihre Endstellung gelangt und dort verbleibt.In this case, the driving element is formed or the sliding on this aligned such that at each located in one of the end positions first Rail one of the sliding elements interacts with one of the driving elements and the another sliding element is out of engagement with the other driving element. This can by the connection with the holding element a targeted pivoting of the lever element done so that this on the interacting with this entrainment acts in such a way that it supports the adjustment so far that the rail connected to the driving element reaches its end position and remains there.

Insbesondere zur Erzielung einer kompakten Einheit und zur Sicherstellung, dass die zum Verstellen der ersten Schiene erforderlichen Kraft nicht unerwünscht hohe Federkräfte überwinden muss, ist vorgesehen, dass in jeder der Endstellungen der ersten Schiene auf das Halteelement in gleicher Richtung, insbesondere in Richtung der ersten Schiene eine Kraftbeaufschlagung erfolgt.In particular, to achieve a compact unit and to ensure that the force required to adjust the first rail not undesirably high spring forces must overcome, that in each of the end positions of the first Rail on the holding element in the same direction, in particular in the direction of the first Rail a force is applied.

Um ein zusätzliches Fixieren des Mitnahmeelementes und damit der ersten Schiene in der jeweiligen Endstellung sicherzustellen, ist vorgesehen, dass das Mitnahmeelement in seiner mit dem Gleitelement wechselwirkenden Fläche eine Ausnehmung aufweist, in der das Gleitelement in der Endstellung der ersten Schiene eingreift. Dabei ist die Ausnehmung insbesondere im Schnittbereich zweier vorzugsweise sich senkrecht zu einander verlaufenden Flächen des Mitnahmeelementes angeordnet.In order to additionally fix the driving element and thus the first rail in ensure the respective end position, it is provided that the driving element has a recess in its interacting with the sliding surface in which the sliding element engages in the end position of the first rail. It is the Recess especially in the intersection of two preferably perpendicular to arranged one another extending surfaces of the driving element.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass zwischen den mit der ersten Schiene verbundenen Mitnahmeelementen das Hebelelement angeordnet ist, wobei das Hebelelement mit seinen Gleitelementen entlang einander zugewandten Flächen des Mitnahmeelementes gleitet wie abrollt. According to a development of the invention it is provided that between the with the first rail connected entrainment elements the lever element is arranged, wherein the lever element facing with its sliding elements along each other Surfaces of the driving element slides as unrolls.

Damit vor Erreichen einer der Endstellungen der ersten Schiene und bei Vorliegen in dieser Endstellung das Hebelelement nur mit einem der Gleitelemente mit einem der Mitnahmeelemente wechselwirkt, ist vorgesehen, dass die Mitnahmeelemente in ihrer einander zugewandten Flächen jeweils zwei zueinander versetzt verlaufende Abschnitte, einem vorspringenden und einem zurückversetzten Abschnitt aufweisen, wobei im jeweiligen vorspringenden Abschnitt die Ausnehmung vorgesehen ist, in der eines der Gleitelemente bei sich in einer der Endstellungen befindlichen ersten Schiene eingreift. Dabei sind die Abschnitte vorzugsweise parallel zueinander und parallel zum Verschiebeweg des Mitnehmers verlaufend angeordnet.Thus before reaching one of the end positions of the first rail and in presence in this end position the lever element only with one of the sliding elements with one of Intermeshing elements interacts, it is provided that the entrainment elements in their mutually facing surfaces each two mutually offset sections, a projecting and a set-back section, wherein in each protruding portion, the recess is provided, in which one of Sliding elements engaged in one of the end positions located first rail. In this case, the sections are preferably parallel to one another and parallel to the displacement path arranged the driver running.

Damit sichergestellt ist, dass in der jeweiligen Endstellung bzw. kurz vor dieser nur ein Gleitelement mit einem Mitnahmeelement wechselwirkt, wohingegen das andere Gleitelement frei ist, verlaufen in Projektion senkrecht zum Verschiebeweg der Mitnahmeelemente die vorspringenden Abschnitte in Richtung des Verschiebewegs beabstandet zueinander.This ensures that in the respective end position or shortly before this only one Sliding element interacts with a driving element, whereas the other Sliding element is free, run in projection perpendicular to the displacement of the driving elements the projecting portions spaced in the direction of the displacement to each other.

Bezüglich der Endlagenüberwachung sollten die vorhandenen zwei Schaltelemente wie Schnappschalter mit ihrem jeweiligen Betätiger mit einer Fläche eines der Mitnahmeelemente wechselwirken, die gegenüberliegend zu der Fläche verläuft, entlang der eines der Gleitelemente des Hebelelementes gleitet. Dies ist jedoch kein zwingendes Merkmal.Regarding the end position monitoring, the existing two switching elements should be like Snap-action switch with its respective actuator with a surface of one of the driving elements interact, which runs opposite to the surface, along the one the sliding elements of the lever element slides. However, this is not a mandatory feature.

Insbesondere ist die Erfindung dadurch gekennzeichnet, dass die Anordnung zwei vorzugsweise als Führungsrohr ausgebildete Führungselemente umfasst, die um jeweils eine ortsfeste Achse schwenkbar sind, dass sich bereichsweise innerhalb der Führungselemente oder dieses teilweise umgebend das axial zu diesem verstellbare bzw. verschiebbare Halteelement wie Gegenhalter erstreckt, dass jeder Gegenhalter der gegenüber dem Führungselement mittels des vorzugsweise dieses umgebenden Federelementes wie Druckfeder federvorgespannt ist, dass die Halteelemente endseitig, um eine gemeinsame und parallel zu den ortsfesten Achsen verlaufenden Achse verschwenkbar sind, die die zweite Achse bildet, von der das mit dem Hebelelement verbundene Gelenkelement ausgeht. Dabei ist beim Verstellen der ersten Schiene und damit der Mitnahmeelemente die zweite Achse entlang einer Geraden verstellbar, die parallel oder in etwa parallel zum Verschiebeweg der Mitnahmeelemente verläuft.In particular, the invention is characterized in that the arrangement two preferably formed as a guide tube guide elements comprises, in each case a fixed axis are pivotable that partially within the guide elements or this partially surrounding the axially adjustable or displaceable to this Retaining element such as counter-holder that extends each counterholder of the opposite the guide element by means of the preferably surrounding spring element how compression spring is spring-biased, that the holding elements end to a common and parallel to the stationary axes extending axis are pivotable, the the second axis forms, of which the articulated element connected to the lever element emanates. It is when adjusting the first rail and thus the driving elements the second axis is adjustable along a straight line parallel or approximately parallel to the Displacement of the driving elements runs.

Insbesondere sind die aus Führungs- und Halteelementen gebildeten Einheiten symmetrisch zu der Geraden angeordnet, entlang der die zweite Achse verstellbar ist.In particular, the units formed by guiding and holding elements are symmetrical arranged to the straight line along which the second axis is adjustable.

Damit die Federkräfte stets in einer Richtung auf das Hebelelement einwirken, verläuft aufgrund der erfindungsgemäßen Konstruktion unabhängig von der Stellung der ersten Schiene die zweite Achse, von der das mit dem Hebelelement verbundene Gelenkelement ausgeht, auf einer Seite einer die ersten Achsen durchsetzenden Gerade, insbesondere zwischen der Geraden und der ersten Schiene.So that the spring forces always act in one direction on the lever element, runs due to the construction according to the invention regardless of the position of the first Rail the second axis from which the articulated element connected to the lever element on one side of a straight line passing through the first axes, in particular between the straight line and the first rail.

Um das Mitnahmeelement zusammen mit der Bewegung der ersten Schiene reibungsarm bei geringer Abstützkonstruktion verstellen zu können, wird das Mitnahmeelement von einer Führungswelle durchsetzt, die von einer Halterung bzw. einem Gehäuse ausgeht, die bzw. das innerhalb eines Schwellenfeldes verlaufen sollte, und zwar unmittelbar oder nahezu unmittelbar unter den Schienen. Hierdurch wird insbesondere das Stopfen eines Gleises nicht behindert.To the driving element together with the movement of the first rail friction to be able to adjust at low support structure, the entrainment of passes through a guide shaft, which starts from a holder or a housing, which should be within a threshold field, directly or almost immediately under the rails. As a result, in particular the plugging of a Track not obstructed.

In bekannter Konstruktion geht von der ersten Schiene ein Kloben aus, der sodann seinerseits über ein Befestigungselement wie Gewindestange mit dem Mitnahmeelement verbunden ist, wobei der Abstand zwischen dem Mitnahmeelement und dem Kloben einstellbar ist. Hierdurch kann der Schaltpunkt des Schaltelementes variiert werden.In a known construction of the first rail goes from a block, which then in turn via a fastener such as threaded rod with the driving element is connected, wherein the distance between the driving element and the block is adjustable. As a result, the switching point of the switching element can be varied.

Der kompakte Aufbau der Anordnung ergibt sich insbesondere auch dadurch, dass die aus Führungs- und Halteelementen gebildeten Einheiten in einer ersten Ebene und die Mitnahmeelemente in einer parallel hierzu verlaufenden zweiten Ebene in der Halterung bzw. im Gehäuse verlaufen, die bzw. das im Schwellenfeld angeordnet ist. The compact construction of the arrangement results in particular from the fact that the from guiding and holding elements formed units in a first plane and the Driving elements in a parallel thereto extending second level in the holder or in the housing, which is arranged in the threshold field.

Das Mitnahmeelement selbst weist eine Quaderform mit in Draufsicht insbesondere einer L- bzw. T-förmigen Geometrie auf.The driving element itself has a cuboid shape with in plan view in particular an L- or T-shaped geometry.

Das Gelenkelement selbst weist zwei Drehachsen auf, von dem eine erste Drehachse mit der das Halteelement durchsetzenden zweiten Achse zusammenfällt. Von der zweiten Drehachse geht ein Schenkel drehbeweglich aus, der Abschnitt des Hebelelementes ist, der vorzugsweise L-förmig ausgebildet ist und dessen Schenkel ebenfalls vorzugsweise einen stumpfen Winkel einschließen. Des Weiteren durchsetzen die zwei Drehachsen ein Platten- oder Laschenelement des Gelenkelementes, wobei das Platten- bzw. Laschenelement in seinem hebelseitigen Randbereich eine Ausnehmung aufweisen kann, in der das dieser naheliegende Gleitelement bei anliegender Position der ersten Schiene eingreift, wobei gleichzeitig das andere Gleitelement in die der der anliegenden Position entsprechenden Endstellung zugeordnete Ausnehmung eines der Mitnahmeelemente eingreift, wobei die Drehachse des Hebelelementes zwischen der Achse des Halteelementes und der zweiten Drehachse des Gelenkelementes verläuft. Hierdurch werden die von den Federelementen hervorgerufenen Kräfte über das Gelenkelement und das Hebelelement auf das Mitnahmeelement derart übertragen, dass dieses das Halten der ersten Schiene in ihrer einen Endstellung unterstützt.The joint element itself has two axes of rotation, of which a first axis of rotation of the holding element passing through the second axis coincides. From the second Axis of rotation is a leg rotatable, which is the section of the lever element, which is preferably L-shaped and its legs also preferably include an obtuse angle. Furthermore, the two axes of rotation prevail Plate or tab element of the hinge element, wherein the plate or tab element in its lever-side edge region may have a recess in the the obvious this sliding element in abutting position of the first rail engages, wherein at the same time the other sliding element in the of the applied position corresponding end position associated with recess of the driving elements engages, wherein the axis of rotation of the lever element between the axis of the holding element and the second axis of rotation of the joint element extends. This will be the forces caused by the spring elements via the joint element and the Transfer lever element on the driving element such that this holding the first rail supported in its one end position.

Die Unterstützung des Verstellens im jeweils vorzugsweise letzten Drittel des Stellwegs erfolgt dadurch, dass das Rollenelement in die dessen Geometrie angepasste Ausnehmung eingreift und durch die sodann einwirkenden Kräfte der Feder das Rollenelement quasi in die Ausnehmung vollständig hineindrückt. The support of the adjustment in each preferably last third of the travel takes place in that the roller element in the geometry adapted to the recess engages and by the then acting forces of the spring roller element almost completely pushed into the recess.

Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich nicht nur aus den Ansprüchen, den diesen zu entnehmenden Merkmalen - für sich und/oder in Kombination -, sondern auch aus der nachfolgenden Beschreibung eines der Zeichnung zu entnehmenden bevorzugten Ausführungsbeispiels.Further details, advantages and features of the invention not only result from the claims, the features to be taken from them - for themselves and / or in Combination - but also from the description below of one of the drawing to be taken preferred embodiment.

In Fig. 1 ist ein Schnitt durch eine Weiche mit einer Backenschiene 12 und einer zu dieser verstellbaren Zungenschiene 14 dargestellt. Hierdurch soll jedoch die erfindungsgemäße Lehre nicht eingeschränkt werden. Vielmehr bezieht sich diese auf den Gleisoberbau, bei der eine erste bewegliche Schiene wie die Zungenschiene 14 zu einer ortsfesten zweiten Schiene wie die Backenschiene 12 verstellbar ist. Aus Gründen der Vereinfachung wird jedoch nachstehend stets von der Zungenschiene 14 als erste Schiene und der Backenschiene 12 als zweite Schiene gesprochen.In Fig. 1 is a section through a switch with a stock rail 12 and one to this adjustable tongue rail 14 shown. As a result, however, the inventive Teaching should not be restricted. Rather, this refers to the track superstructure, in which a first movable rail such as the tongue rail 14 to a stationary second rail as the stock rail 12 is adjustable. Because of However, simplification will always be the first of the tongue rail 14 below Rail and the stock rail 12 spoken as a second rail.

Die Backenschiene 12 ist in bekannter Weise auf einer Rippenplatte befestigt, die von einer Schwelle ausgehen kann. Die Zungenschiene ihrerseits ist auf einem Gleitstuhl gleitend abgestützt. Insoweit wird auf hinlängliche Konstruktionen verwiesen, ohne dass es eines näheren Eingehens bedarf. Gleiches gilt in Bezug auf die Verstellvorrichtung sowie den Verschluss für die Zungenschiene 14 selbst.The stock rail 12 is fixed in a known manner on a ribbed plate, which a threshold can go out. The tongue rail in turn slides on a sliding chair supported. In that regard, reference is made to sufficient constructions without there being any requires closer attention. The same applies with respect to the adjusting device and the Closure for the tongue rail 14 itself.

Wie aus der Prinzipdarstellung gemäß Fig. 1 und 2 erkennbar ist, geht vom Fuß 16 der Zungenschiene 14 ein Zungenkloben 18 mit einer Halterung 20 aus, von der wiederum Gewindewellen 22, 24 ausgehen, die zu Mitnahmeelementen 26, 28 führen, die im Schwellenfeld in einem Gehäuse 30 angeordnet sind. Die Mitnahmeelemente 26, 28, die eine quaderförmige Geometrie aufweisen, sind auf Wellen 32, 34 gleitend abgestützt, die ihrerseits in dem Gehäuse 30 fixiert sind. Durch die Verbindung zwischen dem Zungenkloben 18 bzw. dessen Halterung 20 mit den Mitnahmeelementen 26, 28 über die Gewindestangen 22, 24 oder gleichwirkende Elemente ist sichergestellt, dass sich synchron mit der Bewegung der Zungenschiene 14 die Mitnahmeelemente 26, 28 entlang der Führungswellen 32, 34 mitbewegen. As can be seen from the schematic diagram according to FIGS. 1 and 2, the base 16 of FIG Tongue rail 14, a tongue block 18 with a bracket 20 from, in turn Threaded shafts 22, 24 go out, leading to driving elements 26, 28, in the Threshold field are arranged in a housing 30. The driving elements 26, 28, the have a cuboid geometry, are slidably supported on shafts 32, 34, which in turn are fixed in the housing 30. By the connection between the Tongue pin 18 and its holder 20 with the driving elements 26, 28 via the threaded rods 22, 24 or equivalent elements ensures that synchronously with the movement of the tongue rail 14, the entrainment elements 26, 28th move along the guide shafts 32, 34.

Wie insbesondere die Schnittdarstellung gemäß Fig. 3 verdeutlicht, weisen die Mitnahmeelemente 26, 28 einen rechteckigen Querschnitt auf, wobei sich in Draufsicht eine L-Form (Mitnahmeelement 28) bzw. eine asymmetrische T-Form (Mitnahmeelement 26) ergibt. Durch die entsprechenden Geometrien soll die erfindungsgemäße Lehre gleichfalls nicht beschränkt werden.As illustrated in particular the sectional view of FIG. 3, the entrainment elements 26, 28 a rectangular cross-section, wherein in plan view a L-shape (entrainment element 28) or an asymmetrical T-shape (entrainment element 26) results. By the corresponding geometries, the teaching of the invention should also not be limited.

Die Gewindestangen 22, 24 ermöglichen des Weiteren, dass der Abstand zu dem Zungenkloben 18 einstellbar ist.The threaded rods 22, 24 further allow the distance to the Tongue clamp 18 is adjustable.

Die Mitnahmeelemente 26, 28 weisen in ihren einander zugewandten Flächen 38, 40 jeweils eine Stufe 42, 44 auf, durch die die Flächen 38, 40 in zwei zueinander versetzt verlaufende Abschnitte 46, 48 bzw. 50, 52 unterteilt werden, die außenseitig durch die Flächen 49, 51 und 47, 53 begrenzt sind, die gegenüberliegend und vorzugsweise parallel zueinander verlaufen. Die Außenflächen 47, 51 der vorspringenden Abschnitte 46, 50 verlaufen parallel zueinander und parallel zum Verstellweg der Mitnahme - elemente 26, 28 selbst. In den äußeren, also stufenfernen Ecken der vorspringenden Abschnitte 46, 50 der Mitnahmeelemente 26, 28 sind Aussparungen 54, 56 vorgesehen. Die zurückversetzten Abschnitte 48, 52 können, müssen jedoch nicht parallel zum Verschiebeweg verlaufen. Vielmehr müssen diese allein einen Freiraum für eines von zwei Rollenelementen 78, 80 bilden, wenn das andere Rollenelement mit einer der vorspringenden als Ablaufflächen zu bezeichnenden Flächen 47, 51 wechselwirkt.The entrainment elements 26, 28 have in their mutually facing surfaces 38, 40th in each case a step 42, 44, by which the surfaces 38, 40 offset in two to each other extending sections 46, 48 and 50, 52 are divided on the outside by the Plains 49, 51 and 47, 53 are limited, which are opposite and preferably parallel to each other. The outer surfaces 47, 51 of the projecting portions 46, 50 are parallel to each other and parallel to the adjustment of the entrainment - Elements 26, 28 themselves. In the outer, ie stages distant corners of the projecting Sections 46, 50 of the driving elements 26, 28 are recesses 54, 56 are provided. The recessed portions 48, 52 may but need not be parallel to the displacement path run. Rather, these alone have a free space for one of two Roller elements 78, 80 form when the other roller element with one of the projecting as running surfaces to be designated areas 47, 51 interacts.

Dem einen der Mitnahmeelemente (im Ausführungsbeispiel dem Mitnahmeelement 28) sind des Weiteren zwei Schaltelemente 58, 60 zugeordnet, die mit ihrem jeweiligen Betätiger 62, 64 entlang einer Außenfläche 66 des Mitnahmeelementes 28 gleiten. Dabei verläuft die Außenfläche 66 gegenüberliegend zu der die Stufe 44 aufweisenden Fläche 40 bzw. 51 des Mitnahmeelementes 28.One of the driving elements (in the embodiment, the driving element 28) Furthermore, two switching elements 58, 60 associated with their respective Actuator 62, 64 along an outer surface 66 of the driving element 28 slide. there the outer surface 66 is opposite to the 44 having the surface area 40 and 51 of the driving element 28th

In der mit den Betätigern 62, 64 wechselwirkenden Fläche 66 sind ebenfalls Aussparungen 68, 70 vorhanden, die in versetzt zueinander verlaufenden Ebenen derart angeordnet sind, dass jeweils eine der Ausnehmungen 68, 70 einem der Betätiger 62, 64 und die andere Ausnehmung dem anderen Betätiger zugeordnet sind. Hierdurch wird die Möglichkeit geschaffen, dass beim Verstellen des Mitnahmeelementes 28 dann einer der Betätiger 62, 64 in die ihm zugeordnete Ausnehmung 68, 70 eingreifen kann, wenn sich die Zungenschiene 14 in einer ihrer Endstellungen befindet. Zur Einstellung des Schaltpunktes kann das Mitnahmeelement 28 sowie das Mitnahmeelement 26 über die Gewindestarige 24, 22 zu dem Zungenkloben 18 und damit der Zungenschiene 14 verstellt werden.In the interacting with the actuators 62, 64 surface 66 are also recesses 68, 70 present, which in staggered planes such are arranged, that in each case one of the recesses 68, 70 one of the actuator 62, 64th and the other recess associated with the other actuator. This will be the Possibility created that when adjusting the driving element 28 then one of Actuator 62, 64 in its associated recess 68, 70 can engage when the tongue rail 14 is located in one of its end positions. For setting the switching point can the driving element 28 and the driving element 26 via the Threaded bar 24, 22 to the tongue block 18 and thus the tongue rail fourteenth be adjusted.

Zwischen den Mitnahmeelementen 26, 28 ist um eine ortsfeste Achse 72 das Hebelelement 74 drehbar angeordnet, das zweiarmig ausgebildet ist und eine L-förmige Geometrie mit langem und kurzem Schenkel 76, 82 aufweist. Vom Längsschenkel 76 des Hebelelementes 74 gehen die Rollenelemente oder Gleitrollen 78, 80 aus, die um diametral zu der ortsfesten Achse 72 verlaufende nicht näher bezeichnete Achsen drehbar sind. Im Endbereich des kurzen Schenkels 82 ist ein Gelenkelement 84 drehbar um eine Achse 87 angelenkt. Das Gelenkelement 84 ist platten- oder schaftförmig ausgebildet und weist an seinem entfernt zu der Achse 87 liegenden Ende eine weitere Achse 86 auf, die von Halteelementen 88, 90 durchsetzt ist. Ferner weist das Gelenkelement 84 gleitrollenseitig eine Aussparung 85 auf. Die Halteelemente 88, 90, die auch als Gegenhalter zu bezeichnen sind, erstrecken sich in Führungsrohren 92, 94, die um ortsfeste Achsen 96, 98 schwenkbar sind, die von dem Gehäuse 30 ausgehen und parallel zu den Achsen 87 und 72 verlaufen. Die Achsen 86, 96, 98 werden durch Bolzenelemente 100, 102, 104 gebildet, die die Führungsrohre 92, 94 in ihren Endbereichen bzw. die Gegenhalter 88, 90 in ihren vorderen freien Enden durchsetzen.Between the driving elements 26, 28 is about a stationary axis 72, the lever member 74 rotatably arranged, which is formed with two arms and an L-shaped Long and short leg geometry 76, 82. From the longitudinal leg 76 of the lever member 74 go out of the roller elements or rollers 78, 80, the order Diametrically to the stationary axis 72 extending unspecified axes are rotatable. In the end region of the short leg 82, a joint member 84 is rotatable articulated about an axis 87. The hinge element 84 is plate-shaped or shank-shaped formed and has at its remote from the axis 87 another end Axle 86, which is penetrated by holding elements 88, 90. Furthermore, the joint element 84 sliding side a recess 85 on. The holding elements 88, 90, too are to be referred to as an anvil, extend in guide tubes 92, 94, the order fixed axes 96, 98 are pivotable, which emanate from the housing 30 and parallel to the axes 87 and 72 run. The axes 86, 96, 98 are through Bolt elements 100, 102, 104 are formed, which guide the tubes 92, 94 in their end regions or the counter-holders 88, 90 prevail in their front free ends.

Die Führungsrohre 92, 94 und die Gegenhalter 88, 90 sind umfangsseitig von einer Schraubenfeder 105, 106 oder einem gleichwirkenden Element umgeben, die sich einerseits an einem umlaufenden Kragen 108, 110 der Gegenhalter 88, 90 und andererseits an einem bolzenseitig verlaufenden Anschlag 112, 114 abstützen, der von dem Führungsrohr 92, 94 abragt. The guide tubes 92, 94 and the counter-holders 88, 90 are circumferentially of a Coil spring 105, 106 or a similar element surrounded, which on the one hand on a circumferential collar 108, 110 of the anvil 88, 90 and on the other supported on a bolt-side stop 112, 114, of the Guide tube 92, 94 protrudes.

Der die Gegenhalter 88, 90 verbindende Bolzen 102 durchsetzt folglich auch das Gelenkelement 84, welches gelenkig sowohl mit dem Hebelelement 74, d. h. dessen kürzeren Schenkel 84 und den Gegenhaltern 88, 90 verbunden ist.Consequently, the bolt 102 connecting the counter holders 88, 90 also passes through this Articulated element 84, which articulates both with the lever element 74, d. H. whose shorter leg 84 and the counter-holders 88, 90 is connected.

Wird folglich das Hebelelement 74 verschwenkt, wird diese Bewegung über das Gelenkelement 84 auf die Gegenhalter 88, 90 übertragen, die entgegen der von den Schraubenfedern 105, 106 hervorgerufenen Kraft in die Führungsrohre 92, 94 entsprechend hinein- bzw. herausdrückbar sind. Damit üben das Hebelelement 74 und das Gelenkelement 84 quasi die Funktion von gelenkigen Gliederkettenelementen aus, um eine Bewegung bzw. eine Kraft zu übertragen.Consequently, when the lever member 74 is pivoted, this movement will be via the hinge member 84 transferred to the anvil 88, 90, opposite to the coil springs 105, 106 caused force in the guide tubes 92, 94 in accordance with or are herausdrückbar. Thus, the lever member 74 and the hinge member 84 practice quasi the function of articulated link chain elements to a movement or to transmit a force.

Wie durch die Darstellungen der Fig. 2 und 4 verdeutlicht wird, ist das Hebelelement 74 bzw. der Längsschenkel 76 mit seinen Gleitrollen 78, 80 zu den Mitnahmeelementen 26, 28 derart ausgerichtet, dass die Gleitrollen 78, 80 beim Verstellen der Zungenschiene 14 und damit dem synchronen Mitnehmen der Mitnahmeelemente 26, 28 derart mit den einander zugewandten Flächen 47, 51 der vorspringenden Abschnitte 46, 50 in Abhängigkeit von der Stellung der Zungenschiene 14 wechselwirken, dass diese zusätzlich in ihrer jeweiligen Endstellung durch von den Schraubenfedern 106, 105 über die Gegenhalter 88, 90, das Gelenkelement 84 sowie das Hebelelement 74 und die mit dessen Gleitrollen 78, 80 wechselwirkenden Mitnahmeelemente 26, 28 hervorgerufene Kraft fixiert wird. Auch erfolgt eine Unterstützung der Bewegung vorzugsweise im letzten Drittel des Stellwegs zur jeweiligen Endlage hin.As is illustrated by the illustrations of Figs. 2 and 4, the lever member 74 and the longitudinal leg 76 with its rollers 78, 80 to the driving elements 26, 28 aligned such that the rollers 78, 80 when adjusting the tongue rail 14 and thus the synchronous entrainment of the driving elements 26, 28 such with the mutually facing surfaces 47, 51 of the projecting portions 46, 50 in FIG Depending on the position of the tongue rail 14 interact that this additionally in their respective end position by the coil springs 106, 105 via the anvil 88, 90, the joint member 84 and the lever member 74 and with its casters 78, 80 interacting entrainment elements 26, 28 caused Force is fixed. Also, a support of the movement is preferably carried out in the last third of the travel to the respective end position.

In den entsprechenden Stellungen erfolgt gleichzeitig eine Endlagenüberprüfung mittels der Schaltelemente 58, 60, die als sogenannte Schnappschalter ausgebildet sein können.At the same time, a final position check is carried out in the corresponding positions the switching elements 58, 60, which may be formed as so-called snap-action switch.

In Fig. 2 ist der Zustand der erfindungsgemäßen Anordnung 10 zur Endlagensicherung und -überprüfung der Zungenschiene 14 in ihrer anliegenden Position dargestellt. Dabei befindet sich die Gleitrolle 78 des Hebelelementes 74 in der Aussparung 54 des Mitnahmeelementes 26, wobei die von den Schraubenfedern 105, 106 auf die Gegenhalter 88, 90 einwirkenden Kräfte über das Gelenkelement 84 und das Hebelelement 74 mittels der Gleitrolle 78 auf das Mitnahmeelement 26 derart übertragen wird, dass dieses eine Krafteinleitung entgegen eines Verstellens - im Ausführungsbeispiel also entgegen einer Bewegung nach oben - erfährt.
