Abstract

The slide chair (28) is for railway points. It has a continuous passage (68) extending in longitudinal direction of the rails. The spring element (80) extends through the passage. The counter bearings (74,76) are located within the areas of the passage openings (70,72) in the sides of the slide chair. The spring element is bar-shaped and eccentric. When tensioned it supports itself on the base (82) of the passage and on the counter bearings. Each counter bearing is an element projecting from the bed plate (10), with an aperture (78,80) which is aligned with openings of the passage.

Description

Die Erfindung bezieht sich auf einen Gleitstuhl zum Abstützen einer zur einer ersten Schiene wie Backenschiene verstellbaren zweiten Schiene wie Weichenzunge, wobei der Gleitstuhl lösbar auf einer Unterlageplatte wie Rippenplatte mittels eines Federelementes festlegbar ist, das sich zum einem in einer Ausnehmung des Gleitstuhls erstreckt und zum anderen an seitlich entlang dem Gleitstuhl verlaufenden, von der Unterlageplatte ausgehenden Gegenlagern abstützbar ist.The invention relates to a sliding chair for supporting a second rail, such as a switch tongue, which can be adjusted to a first rail such as a stock rail, the sliding chair being releasably fixable on a base plate such as a ribbed plate by means of a spring element which extends on the one hand in a recess in the sliding chair and on the other can be supported on counter bearings extending laterally along the sliding chair and extending from the base plate.

Ein entsprechender Gleitstuhl ist z.B. der DE 38 11 408 C2 zu entnehmen. Dabei erstreckt sich das in Draufsicht U-förmige Federelement mit seinen Seitenschenkeln in Längsrichtung des Gleitstuhls, also senkrecht zur Längsrichtung der Schienen. Die Erstreckung des Gleitstuhls ist dabei derart, daß die Weichenzunge sowohl in ihrer anliegenden als auch in ihrer abliegenden Stellung auf dem Gleitstuhl abgestützt ist. Nach der DE 30 04 944 A1 geht von einem Gleitstuhl ein L-förmiges Federelement aus, über das eine Backenschiene niedergehalten wird. Um einen Gleitstuhl federnd auf einer Grundplatte zu spannen, ist nach der DE 41 12 926 A1 ein hufeisenförmiges oder ringsförmiges geschlitztes Federelement vorgesehen.A corresponding sliding chair is e.g. can be found in DE 38 11 408 C2. The U-shaped spring element in plan view extends with its side legs in the longitudinal direction of the sliding chair, ie perpendicular to the longitudinal direction of the rails. The extension of the sliding chair is such that the switch tongue is supported on the sliding chair both in its adjacent and in its remote position. According to DE 30 04 944 A1, an L-shaped spring element is based on a sliding chair, via which a stock rail is held down. In order to tension a sliding chair resiliently on a base plate, a horseshoe-shaped or ring-shaped slotted spring element is provided according to DE 41 12 926 A1.

Der vorliegenden Erfindung liegt das Problem zugrunde, einen Gleitstuhl der eingangs genannten Art so weiterzubilden, daß dieser überaus kompakt ausbildbar ist, wobei jedoch gleichzeitig sichergestellt ist, daß der Gleitstuhl im hinreichenden Umfang auf der Unterlageplatte festlegbar ist und mittelbar oder unmittelbar die erste Schiene wie Backenschiene niederhält.The present invention is based on the problem of developing a sliding chair of the type mentioned at the outset in such a way that it can be designed to be extremely compact, but at the same time it is ensured that the sliding chair can be fixed to a sufficient extent on the base plate and indirectly or directly the first rail such as a stock rail holds down.

Erfindungsgemäß wird das Problem im wesentlichen dadurch gelöst, daß der Gleitstuhl eine durchgehende, in Längsrichtung der Schiene verlaufende Durchbrechung als die von dem Federelement durchsetzte Ausnehmung aufweist, wobei jeweils ein Gegenlager im Bereich jeweiliger an einer Seitenfläche des Gleitstuhls verlaufender Öffnung der Durchbrechung angeordnet ist.According to the invention, the problem is essentially solved in that the sliding chair has a continuous opening running in the longitudinal direction of the rail as the recess penetrated by the spring element, a counter bearing being arranged in the area of the opening of the opening running on one side surface of the sliding chair.

Durch die erfindungsgemäße Lehre ist der Vorteil gegeben, daß das Federelement nicht mehr in Längsrichtung des Gleitstuhls verlaufen muß, um diesen zu sichern und gleichzeitig mittels des Gleitstuhls die erste Schiene wie Backenschiene niederzuhalten. Dies wiederum bedeutet, daß der Gleitstuhl verkürzt werden kann, wobei allein eine Länge benötigt wird, die ein sicheres Abstützen der zweiten Schiene dann sicherstellen muß, wenn diese an der ersten Schiene anliegt. Demgegenüber kann in abliegender Stellung der zweiten Schiene diese außerhalb oder weitgehend außerhalb des Gleitstuhls verlaufen. Hierdurch ergibt sich insbesondere der Vorteil, daß der Gleitstuhl sich nur im geringen Umfang senkrecht zur Längsrichtung der Schiene in einem Schotterbett erstreckt, so daß unmittelbar neben dem Gleitstuhl verlaufende Schwellen mit üblichen Maßnahmen und Maschinen gestopft werden können. Würden dagegen Gleitstühle zum Einsatz gelangen, die in gewohnter Weise die zweite Schiene auch in ihrer abliegenden Stellung abstützten, so würden dann Probleme hinsichtlich des Stopfens benachbarter Schwellen auftreten, wenn der Gleitstuhl nicht von einer Schwelle ausgeht, sondern zwischen zwei Schwellen verläuft.The teaching according to the invention has the advantage that the spring element no longer has to run in the longitudinal direction of the sliding chair in order to secure it and at the same time hold down the first rail like the stock rail by means of the sliding chair. This in turn means that the sliding chair can be shortened, only a length being required which must ensure that the second rail is securely supported when it abuts the first rail. In contrast, in the remote position of the second rail, it can run outside or largely outside the sliding chair. This results in particular in the advantage that the sliding chair extends only to a small extent perpendicular to the longitudinal direction of the rail in a ballast bed, so that sleepers running directly next to the sliding chair can be stuffed with conventional measures and machines. If, on the other hand, sliding chairs were used, which in the usual way also supported the second rail in its remote position, problems regarding the stuffing of neighboring sleepers would arise if the sliding chair did not start from one threshold, but ran between two sleepers.

Insbesondere ist vorgesehen, daß das Federelement ein stabförmiges exzenterförmiges Federelement ist, das sich im gespannten Zustand zum einem im Bodenbereich der Durchbrechung und zum anderen an den Gegenlagern abstützt.In particular, it is provided that the spring element is a rod-shaped, eccentric spring element which, in the tensioned state, is supported on the one hand in the bottom region of the opening and on the other hand on the counter bearings.

Bei den Gegenlagern selbst handelt es sich vorzugsweise jeweils um ein plattenförmiges von der Unterlage senkrecht nach oben abragendes Element mit einer Öffnung, die zu der Öffnung der Durchbrechung in dem Gleitstuhl fluchtet.The counter bearings themselves are preferably each a plate-shaped element which projects vertically upwards from the base and has an opening which is aligned with the opening of the opening in the sliding chair.

Der Gleitstuhl selbst kann sich mit seinem schienenseitigen Ende mittelbar oder unmittelbar auf dem Fuß der ersten Schiene abstützen und ist mit seinem schienenabgewandten Ende in einer im Schnitt U-förmigen Aufnahme, die aus Kunststoff bestehen kann, festgelegt.The sliding chair itself can be supported directly or indirectly on the foot of the first rail with its rail-side end and, with its end facing away from the rail, is in a U-shaped receptacle made of plastic can exist.

Um einen kompakten Aufbau der Unterlageplatte mit dem auf diesem lösbar angeordneten Gleitstuhl zur erzielen, ist des weiteren vorgesehen, daß seitlich der Durchbrechung des Gleitstuhls Befestigungen für die Unterlage verlaufen. Dabei ist die Unterlage selbst vorzugsweise mit einem Träger verbunden, der seinerseits von aufeinanderfolgenden Schwellen, insbesondere von einer normalen Schwelle wie Betonschwelle und einer Hohlschwelle ausgeht. Dabei durchsetzen die Befestigungselemente wie Schrauben sowohl die Unterlage als auch den Träger, um auf diese Weise die Unterlagen im erforderlichen Umfang mit den Träger zu verbinden. Vorzugsweise ist allein im Bereich jeden Gegenlagers jeweils eine Befestigung wie Schraube zum Verbinden der Unterlageplatte mit dem Träger vorgesehen.In order to achieve a compact structure of the base plate with the slide chair which is detachably arranged on it, it is further provided that fastenings for the base run laterally through the opening of the slide chair. The underlay itself is preferably connected to a carrier, which in turn is based on successive sleepers, in particular a normal sleeper such as a concrete sleeper and a hollow sleeper. The fastening elements such as screws penetrate both the base and the carrier in order to connect the documents to the carrier to the required extent. A fastening such as a screw for connecting the base plate to the carrier is preferably provided in the area of each counter bearing alone.

Gleichzeitig dienen die Befestigungen als Sicherungen für ein unkontrolliertes Entfernen des Federlementes, welches vorzugsweise im ungespannten Zustand einen gebogenen Verlauf aufweist und sowohl mittig als auch im Endbereich mit wulstartigen Verstärkungen zum Abstützen an dem Boden der Durchbrechung bzw. der Gegenlager versehen ist.At the same time, the fastenings serve as safeguards for uncontrolled removal of the spring element, which preferably has a curved course in the untensioned state and is provided with bead-like reinforcements both in the middle and in the end region for support on the bottom of the opening or the counter bearing.

Ferner kann das Federlement zumindest an einem Ende, vorzugsweise an jedem Ende, als Mehrkantkopf ausgebildet sein, um das Federelement im erforderlichen Umfang in der Durchbrechung zu drehen und zu verspannen bzw. zu lösen.Furthermore, the spring element can be designed as a polygonal head at least at one end, preferably at each end, in order to rotate and tension or release the spring element in the opening to the required extent.

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 von der Zeichnung zu entnehmenden bevorzugten Ausführungsbeispielen.Further details, advantages and features of the invention result not only from the claims, the features to be extracted from them - by themselves and / or in combination - but also from the following description of preferred exemplary embodiments which can be found in the drawing.

In den Figuren ist eine Unterlageplatte wie Rippenplatte 10 auf einem Träger 12 mittels Schrauben 14 und 16 befestigt, wobei sich der Träger 12 zwischen zwei aufeinanderfolgenden Schwellen, insbesondere zwischen einer üblichen Schwelle wie Betonschwelle und einer Hohlschwelle erstrecken kann. Hierdurch soll jedoch die erfindungsgemäße Lehre nicht eingeschränkt werden.In the figures, a base plate, such as rib plate 10, is fastened to a carrier 12 by means of screws 14 and 16, the carrier 12 being able to extend between two successive sleepers, in particular between a conventional sleeper such as a concrete sleeper and a hollow sleeper. However, this is not intended to limit the teaching according to the invention.

Der Träger 12 weist im Schnitt eine T-Form auf, dessen Flansch 18, auf dem die Rippenplatte 10 befestigt ist, sich entlang der Oberseite einer üblichen Schwelle erstreckt bzw. der mit einer Hohlschwelle, innerhalb der ein Weichenverschluß angeordnet sein kann, verschweißt sein kann.The carrier 12 has a T-shape in section, the flange 18, on which the rib plate 10 is fastened, extends along the top of a conventional sleeper or which can be welded to a hollow sleeper, within which a switch lock can be arranged .

Ferner ist der Träger 12 vorzugsweise derart ausgelegt, daß sich im Bereich der Rippenplatte eine Einfederung ergibt, die Einfederungen von Abstützungen entspricht, die auf üblichen Schwellen befestigt sind.Furthermore, the carrier 12 is preferably designed such that there is a deflection in the region of the rib plate, which corresponds to the deflection of supports which are fastened on conventional sleepers.

Auf der Rippenplatte 10 ist eine erste Schiene in Form einer Backenschiene 20 befestigt, die mit ihrem Fuß 22 an einer Seite an Anschlägen 24, 26 anliegt und über nicht dargestellte Spannbügel niedergehalten wird. Auf der gegenüberliegenden Seite wird der Fuß 22 mittels eines Gleitstuhls 28 niedergehalten, dessen Fixierung nachstehend näher beschrieben wird.On the ribbed plate 10, a first rail in the form of a stock rail 20 is fastened, which rests with its foot 22 on one side against stops 24, 26 and is held down by tensioning brackets (not shown). On the opposite side, the foot 22 is held down by means of a sliding chair 28, the fixing of which is described in more detail below.

Die Rippenplatte 10 weist in Draufsicht eine T-Form auf, wobei der Querschenkel 30 endseitig von den Schrauben 14 und 16 durchsetzt wird, um die Rippenplatte 10 auf dem Flansch 18 des Trägers 10 zu befestigen.The rib plate 10 has a T-shape in plan view, the cross leg 30 being penetrated at the end by the screws 14 and 16 in order to fix the rib plate 10 on the flange 18 of the carrier 10.

Ferner ist die Rippenplatte 10 in einer elastischen Zwischenlage 32 einvulkanisiert, die als erstes Federelement wirkt. Die Zwischenlage 32 sollte dabei eine lineare Kennlinie aufweisen, d.h. Krafteinwirkung und Federweg sollten proportional zueinander sein. Oberhalb der Rippenplatte 10 verläuft ein zweites Federelement, das im Ausführungsbeispiel als rippenartige Vorsprünge 34, 36, 40, 42 ausgebildet ist, die jeweils von einer Kappe 44, 46 bzw. von in dieser vorhandenen Ausnehmungen 35, 38, 41, 42 in nachstehend beschriebener Art und Weise aufgenommen werden. Die Kennlinie des aus den rippenartigen Abschnitten 34, 36, 40 und 42 gebildeten zweiten Federelementes weist in nicht vorgespanntem Zustand einen flacheren Verlauf als das von der Zwischenlage 32 gebildete erste Federelement auf. Entsprechend der Lehre der WO 94/08093 wird das von den rippenartigen Abschnitten 34, 36, 40, 42 gebildete zweite Federelement und damit die Rippenplatte 10 gegenüber dem Träger 12 derart vorgespannt, daß sich ein Gesamtverlauf bestehend aus dem flachen Abschnitt sowie einem steil ansteigendem Abschnitt ergibt. Dieser steil ansteigende Abschnitt wird dadurch erreicht, daß die Abschnitte 34, 36, 40, 42 mittels der Kappen 44, 46 derart vorgespannt werden, daß diese allseitig komprimiert werden. In diesem Fall können die rippenartigen Vorsprünge 34, 36, 40 und 42 Federeigenschaften im eigentlichen Sinne nicht mehr ausüben, so daß sich der steile Verlauf ergibt.Furthermore, the ribbed plate 10 is vulcanized into an elastic intermediate layer 32, which acts as the first spring element. The intermediate layer 32 should have a linear characteristic, i.e. Force and travel should be proportional to each other. Above the rib plate 10 runs a second spring element, which in the exemplary embodiment is designed as rib-like projections 34, 36, 40, 42, each of which has a cap 44, 46 or recesses 35, 38, 41, 42 present in it in the manner described below Way to be included. The characteristic curve of the second spring element formed from the rib-like sections 34, 36, 40 and 42 has a flatter course in the non-prestressed state than the first spring element formed by the intermediate layer 32. According to the teaching of WO 94/08093, the second spring element formed by the rib-like sections 34, 36, 40, 42 and thus the rib plate 10 is pretensioned relative to the carrier 12 in such a way that there is an overall course consisting of the flat section and a steeply rising section results. This steeply rising section is achieved in that the sections 34, 36, 40, 42 are prestressed by means of the caps 44, 46 in such a way that they are compressed on all sides. In this case, the rib-like projections 34, 36, 40 and 42 can no longer exert spring properties in the actual sense, so that the steep course results.

Um diesen Kompressionsbereich zu erzielen, werden die Kappen 44, 46 mittels der Schrauben 14, 16 angezogen, so daß die in den Kappen 44, 46 vorhandenen Ausnehmungen 35, 38, 41, 42 von den rippenartigen Abschnitten 34, 36, 40, 42 voll ausgefüllt werden. Um dies zu erreichen, weisen die rippenartigen Abschnitte 34, 36, 40, 42 im entspannten Zustand bodenseitig jeweils einen und in der Fig. 4 gestrichelten Vorsprung 48, 50, 52, 54 auf, dem eine entsprechende Vertiefung in der Oberseite der rippenförmigen Abschnitte 34, 36, 40, 42, zugeordnet ist. Diese sind ebenfalls in der Figur angedeutet und weisen die Bezugszeichen 56, 58, 60 und 62 auf. Wird nunmehr erwähntermaßen die Kappe 44 bzw. 46 über die Schraube 14 bzw. 16 angezogen, so werden die Ausnehmungen 35, 38, 41, 43 in den Kappen 44, 46 vollständig von den rippenartigen Abschnitten 34, 36, 40, 42 ausgefüllt und zeigen eine im Schnitt in etwa rechteckförmige bzw. hutförmige Geometrie, die durch den schraffierten Bereich innerhalb der Kappe 44, 46 angedeutet wird.In order to achieve this compression range, the caps 44, 46 are tightened by means of the screws 14, 16, so that the recesses 35, 38, 41, 42 present in the caps 44, 46 are full of the rib-like sections 34, 36, 40, 42 fill out. In order to achieve this, the rib-like sections 34, 36, 40, 42 each have a projection 48, 50, 52, 54, which is dashed in FIG. 4 and has a corresponding depression in the top of the rib-shaped sections 34 in the relaxed state , 36, 40, 42, is assigned. These are also indicated in the figure and have the reference numerals 56, 58, 60 and 62. If the cap 44 or 46 is now tightened as mentioned above via the screw 14 or 16, the recesses 35, 38, 41, 43 in the caps 44, 46 are completely filled and shown by the rib-like sections 34, 36, 40, 42 an approximately rectangular or hat-shaped geometry in section, which is indicated by the hatched area within the cap 44, 46.

Durch die Zwischenlage 32 als erstes Federelement und die rippenförmigen Abschnitte 34, 36, 40, 42 als zweites Federelement ergibt sich ein Gesamtfedersystem, welches eine geknickte Kennlinie entsprechend der WO 94/08093 aufweist, die bewirkt, daß das System im statischen Zustand hart und im dynamischen Zustand, also dann, wenn die Schiene 20 von einem Fahrzeug durchfahren wird, weiche Eigenschaften aufweist.The intermediate layer 32 as the first spring element and the rib-shaped sections 34, 36, 40, 42 as the second spring element result in an overall spring system which has a kinked characteristic curve in accordance with WO 94/08093, which causes the system to be hard in the static state and dynamic state, ie when the rail 20 is traversed by a vehicle, has soft properties.

Der Gleitstuhl 28 weist senkrecht zur Längsachse der Schiene 20 eine Erstreckung auf, die nur geringfügig länger als die Breite eines Fußes 64 einer als zweite Schiene bezeichneten Weichenzunge 66 ist, die zu der Backenschiene 20 verstellbar ist, also entweder an der Backenschiene 20 anliegen soll (durchgezogene Darstellung in Fig. 2) oder zu dieser beabstandet ist (gestrichelte Darstellung). Dabei verdeutlicht die Fig. 2, daß in der abliegenden Stellung der Weichenzunge 66 diese im wesentlichen außerhalb des Gleitstuhls 28 verläuft und sodann von nicht dargestellten Rollenelementen abgestützt ist, die von benachbarten Schwellen ausgehen können.The sliding chair 28 has an extension perpendicular to the longitudinal axis of the rail 20, which is only slightly longer than the width of a foot 64 of a switch tongue 66, referred to as the second rail, which is adjustable relative to the stock rail 20, that is, it should either rest against the stock rail 20 ( solid representation in Fig. 2) or spaced apart (dashed representation). 2 shows that in the remote position of the switch tongue 66, the switch tongue extends essentially outside the sliding chair 28 and is then supported by roller elements, not shown, which can originate from adjacent sleepers.

Durch die kurze Erstreckung des Gleitstuhls 28 (Länge quer zur Schienenlängsrichtung z.B. 150 mm und Breite z.B. 120 mm) ergibt sich der Vorteil, daß der Gleitstuhl 28 seitlich nicht über den Träger 12 vorsteht, so daß problemlos ein Stopfen von benachbarten Schwellen mit üblichen Werkzeugen und Maschinen möglich ist.Due to the short extension of the sliding chair 28 (length transversely to the longitudinal direction of the rail, for example 150 mm and width, for example 120 mm), there is the advantage that the sliding chair 28 does not protrude laterally beyond the carrier 12, so that it is easy to plug adjacent sleepers with conventional tools and Machines is possible.

Trotz der Kürze des Gleitstuhls 28 ist dieser jedoch sicher auf der Rippenplatte 10 fixierbar und hält gleichzeitig den Schienenfuß 22 der Backenschiene 20 im erforderlichen Umfang nieder.Despite the brevity of the sliding chair 28, however, it can be securely fixed on the ribbed plate 10 and at the same time holds down the rail foot 22 of the stock rail 20 to the required extent.

Hierzu weist der Gleitstuhl 28 eine sich in Längsrichtung der Backenschiene 20 wie parallel zu dieser verlaufende durchgehende Durchbrechung 68 auf. Seitlich von Öffnungen 70, 72 der Durchbrechung 68 und von der Rippenplatte 10 ausgehend verlaufen plattenförmige Gegenlager 74, 76 mit Öffnungen 78, 80, die vorzugsweise zu den Öffnungen 70, 72 der Durchbrechung 68 fluchten.For this purpose, the sliding chair 28 has a continuous opening 68 which runs in the longitudinal direction of the stock rail 20 and runs parallel to it. Plate-shaped counter bearings 74, 76 with openings 78, 80, which preferably align with the openings 70, 72 of the opening 68, extend laterally from openings 70, 72 of the opening 68 and from the rib plate 10.

Uni den Gleitstuhl 28 auf der Rippenplatte 10 zu fixieren, wird in die Durchbrechung 68 über eine der Öffnungen 74 bzw. 76 ein stabförmiges Federelement 80 hineingeschoben und sodann mittels zumindest eines Werkzeuges derart gedreht und damit verspannt, daß sich das Federelement 80 einerseits am Boden 82 der Durchbrechung 68 und andererseits an den oberen Innenflächen 84, 86 der Gegenlager 74, 76 bzw. den Öffnungen 78, 80 dieser abstützt.Uni to fix the sliding chair 28 on the ribbed plate 10, a rod-shaped spring element 80 is pushed into the opening 68 via one of the openings 74 and 76 and then rotated in this way by means of at least one tool and thus clamped that the spring element 80 is supported on the one hand on the bottom 82 of the opening 68 and on the other hand on the upper inner surfaces 84, 86 of the counter bearing 74, 76 or the openings 78, 80 of the latter.

Im Ausführungsbeispiel ist das Federelement 80 im entspannten Zustand bogenförmig geformt (Fig. 5) und weist sowohl in seinem Mittenbereich 88 als auch in seinen Endbereichen 90, 92 wulstartige Verstärkungen auf, die einerseits am Boden 82 der Durchbrechung 68 bzw. an den oberen Innenflächen 84, 86 der Öffnungen 78) 80 anliegen können.In the exemplary embodiment, the spring element 80 is arched in the relaxed state (FIG. 5) and has bead-like reinforcements both in its central region 88 and in its end regions 90, 92, which reinforcements on the one hand on the bottom 82 of the opening 68 or on the upper inner surfaces 84 , 86 of the openings 78) 80 can rest.

Um das Federelement 80 drehen und damit spannen zu können, weist dieses endseitig Mehrkantköpfe 94, 96 auf, die von einem Werkzeug erfaßt werden können.In order to be able to rotate and tension the spring element 80, it has polygonal heads 94, 96 at the end, which can be gripped by a tool.

Zwischen den Gegenlagern 74 und 76 und den Kappen 44, 46 erstrecken sich die Mehrkantköpfe 94, 96 bei ordnungsgemäß montiertem Gleitstuhl 28. Diese Bereiche werden sodann von Kappen 100, 102 abgedeckt.The polygonal heads 94, 96 extend between the counter bearings 74 and 76 and the caps 44, 46 when the sliding chair 28 is properly installed. These areas are then covered by caps 100, 102.

Zur Lagefixierung des lösbar auf der Rippenplatte 10 befestigten Gleitstuhls 28 ist dieser in einer im Schnitt U-förmigen Aufnahme 104 positioniert, die aus Kunststoff bestehen kann und sich in Längsrichtung der Backenschiene 20 erstreckt. Ferner ist der lichte Abstand zwischen den Gegenlagern 74, 76, die senkrecht von der Oberfläche der Rippenplatte 10 abstehen, in etwa gleich der Breite der Rippenplatte 28.To fix the position of the sliding chair 28 releasably attached to the ribbed plate 10, the sliding chair 28 is positioned in a U-shaped receptacle 104, which can be made of plastic and extends in the longitudinal direction of the stock rail 20. Furthermore, the clear distance between the counter bearings 74, 76, which protrude perpendicularly from the surface of the rib plate 10, is approximately equal to the width of the rib plate 28.

Des weiteren stützt sich die Rippenplatte 10 mit ihrem vorderen Ende auf dem Fuß 22 der Backenschiene 20 ab, um diesen niederzuhalten und somit ein Kippen der Backenschiene 20 beim Durchfahren eines Fahrzeuges auszuschließen.Furthermore, the rib plate 10 is supported with its front end on the foot 22 of the stock rail 20 in order to hold it down and thus prevent the stock rail 20 from tipping when a vehicle is being driven through.

Um ein unerwünschtes Wandern des Gleitstuhls 28 von der Backenschiene 20 weg zusätzlich zu verhindern, ist der Gleitstuhl 28 endseitig, also auf der zur Backenschiene 20 fernliegenden Seite, von einer in Längsrichtung der Backenschiene 20 und von der Rippenplatte 10 ausgehenden Rippe 106 gesichert.In order to additionally prevent undesirable migration of the sliding chair 28 away from the stock rail 20, the sliding chair 28 is secured at the end, that is to say on the side remote from the stock rail 20, by a rib 106 extending in the longitudinal direction of the stock rail 20 and from the rib plate 10.
