At least one spring component (14,15) is provided which is tensionable between locators and abutments (28,30,32,34,36,38) which directly or indirectly are formed out of the plate-shaped component. The plate-shaped component is releasably fixable on the rib plate by a spring component (24,26) and supports as a holding down device for the rail foot. The spring component supports on a section of the plate-shaped component extending area-wise over the rail foot. From the rib plate a first securing device is formed, which penetrates the plate-shaped component and secures it area-wise.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Niederhalten eines Schienenfußes einer Fahrschiene mit zugeordnetem von einem Stützbock oder Radlenkerständer ausgehenden Radlenker, umfassend ein sich zwischen von einer Unterlage - wie Rippenplatte ausgehenden Seitenstützen oder -wangen des Radlenkerständers sich erstreckendes plattenförmiges Element sowie ein Federelement, das zwischen Auf- und Widerlagern spannbar ist, die von der Unterlageplatte bzw. dem plattenförmigen Element ausgehen.The invention relates to a device for holding down a rail foot of a running rail with an associated wheel handlebar starting from a support bracket or wheel handlebar stand, comprising a plate-shaped element extending between a base - like ribbed plate-extending side supports or cheeks of the wheel handlebar stand, as well as a spring element which between Support and abutments can be clamped, which start from the base plate or the plate-shaped element.

Eine entsprechende Vorrichtung ist der DE-AS 2 042 489 zu entnehmen. Dabei bildet das als Fußplatte bezeichnete plattenförmige Element mit den Seitenstützen eine Einheit. Die Schiene selbst wird mittels des Federelementes niedergehalten, welches in eine Ausnehmung schiebbar ist, die sich in der Fußplatte erstreckt. Die Ausnehmung weist eine die Spannung des Federelements bewirkende Ausformung auf. Bricht das Federelement, so wirken Vorsprünge der Fußplatte als zusätzlicher Kippschutz für den Schienenfuß. Losgelöst hiervon ist jedoch das Einbringen bzw. Entfernen des eine U-förmige Geometrie aufweisenden Federelements aufwendig. Auch kann sich Schmutz in der Ausnehmung ablagern, die ein Auswechseln des Federelementes erschweren oder sogar unmöglich machen.A corresponding device can be found in DE-AS 2 042 489. The plate-shaped element called the base plate forms a unit with the side supports. The rail itself is held down by means of the spring element which can be pushed into a recess which extends in the footplate. The recess has a shape which causes the tension of the spring element. If the spring element breaks, protrusions on the footplate act as additional tilt protection for the rail foot. Disconnected from this, however, the introduction or removal of the spring element having a U-shaped geometry is complex. Dirt can also be deposited in the recess, making it difficult or even impossible to replace the spring element.

Der vorliegenden Erfindung liegt das Problem zugrunde, eine Vorrichtung der zuvor genannten An so weiterzubilden, daß auch bei beengten Platzverhältnissen ein sicheres Niederhalten der Fahrschiene möglich ist. Gleichzeitig soll sichergestellt sein, daß definierte Krafteinleitungen in den Fuß der Fahrschiene erfolgen, um diesen niederzuhalten.The present invention is based on the problem of developing a device of the type mentioned above in such a way that a safe holding down of the running rail is possible even in confined spaces. At the same time, it should be ensured that defined force transmissions take place in the foot of the running rail in order to hold it down.

Das Problem wird erfindungsgemäß im wesentlichen dadurch gelöst, daß das plattenförmige Element lösbar auf der Unterlageplatte mittels des Federelements festlegbar ist und als Niederhalter für den Schienenfuß sich auf diesem abstützt, daß das Federelement auf einen sich bereichsweise über den Schienenfuß erstreckenden ersten Abschnitt des plattenförmigen Elements als Auflager abstützt und daß von der Unterlageplatte ein erste Sicherung ausgeht, die den Niederhalter durchsetzt und von diesem bereichsweise überfaßt ist. Dabei sind insbesondere zwei als Stabfedern ausgebildete Federelemente zur Sicherung des Niederhalters vorgesehen, die sich entlang der Längsseiten des Niederhalters und parallel innenseitig entlang der Seitenstützen bzw. - wangen des Radlenkerständers erstrecken.The problem is solved according to the invention essentially in that the plate-shaped element is releasably fixable on the base plate by means of the spring element and is supported as a hold-down device for the rail foot on this that the spring element as a first portion of the plate-shaped element extending over the rail foot as Support supports and that a first fuse starts from the base plate, which passes through the hold-down and is covered by this in some areas. In particular, two spring elements designed as rod springs are provided for securing the hold-down device, which extend along the long sides of the hold-down device and parallel on the inside along the side supports or cheeks of the wheel control arm stand.

Die das bzw. die Federelemente spannenden Widerlager gehen einerseits von der Unterlageplatte und andererseits von den Seitenstützen des Radlenkerständers aus.The abutments that tension the spring element (s) start on the one hand from the base plate and on the other hand from the side supports of the wheel handlebar stand.

Dadurch, daß das Federelement über zwei mittelbar oder unmittelbar von einer Unterlageplatte ausgehende Widerlager spannbar ist, ist es nur noch erforderlich, daß der den Schienenfuß niederhaltende Niederhalter ein Auflager besitzt, so daß die Erstreckung des Niederhalters quer zur Längsrichtung der Schiene überaus kurz gewählt werden kann. Dabei wirkt das Federelement auf das Auflager derart, daß der Niederhalter selbst nicht instabil, also kippen kann, sondern vielmehr Kräfte in den Schienenfuß derart einleitet, daß dieser in erforderlichem Umfang niedergehalten wird.Characterized in that the spring element can be tensioned directly or indirectly from two abutments starting from a base plate, it is only necessary that the hold-down holding down the rail foot has a support, so that the extension of the hold-down transverse to the longitudinal direction of the rail can be chosen extremely short . The spring element acts on the support in such a way that the hold-down device itself cannot unstable, ie tilt, but rather introduces forces into the rail foot in such a way that it is held down to the required extent.

Auch wenn aus Gründen der Vereinfachung von einem plattenförmigen Element gesprochen wird, über das die Schiene niedergehalten wird, so kann auch eine andere Geometrie gewählt werden, wobei es unbeachtlich ist, wie die Oberfläche des plattenförmigen Elementes ausgebildet ist, da neben der Funktion des Niederhaltens eine andere nicht erfüllt werden muß.Even if, for reasons of simplification, one speaks of a plate-shaped element via which the rail is held down, a different geometry can also be selected, it being irrelevant how the surface of the plate-shaped element is designed, since in addition to the function of holding down a others do not have to be met.

Insoweit unterscheidet sich die erfindungsgemäße Vorrichtung wesentlich von einem auch die Funktion eines Niederhalters ausübenden Gleitstuhls, wie dieser z. B. der DE 42 29 014 A 1 oder DE 41 12 926 A1 zu entnehmen ist, zudem das Auflager außerhalb des Schienenfußes verläuft, so daß sich gegebenenfalls ungünstige Hebelkräfte in dem Federelement ausbilden können.In this respect, the device according to the invention differs significantly from a sliding chair which also functions as a hold-down device, such as this. B. DE 42 29 014 A1 or DE 41 12 926 A1, the support outside of the rail foot runs, so that possibly unfavorable lever forces can form in the spring element.

In einer besonders hervorzuhebenden Weiterbildung der Erfindung ist vorgesehen, daß die erste Sicherung im Schnitt eine L-förmige Geometrie mit senkrecht von der Unterlageplatte abragendem Längsschenkel und parallel zu der Unterlageplatte verlaufendem Querschenkel aufweist, der oberhalb eines Abschnitts des Niederhalters verläuft. Dabei kann der Querschenkel außenseitig bündig zur Oberfläche des Niederhalters oder in diesen eingelassen verlaufen.In a particularly noteworthy development of the invention, it is provided that the first securing means has an L-shaped geometry with a longitudinal leg protruding perpendicularly from the base plate and a transverse leg running parallel to the base plate and running above a section of the hold-down device. The cross leg can be flush on the outside with the surface of the hold-down device or embedded therein.

Die Sicherung bzw. ein L-förmiges oder eine gleichwirkende Geometrie aufweisendes Sicherungselement und die Aussparung des Niederhalters sind dabei derart aufeinander abgestimmt, daß sich der Niederhalter ausschließlich oder im wesentlichen ausschließlich in Längsrichtung der Fahrschiene verschieben kann, so daß zusätzliche Sicherungen, die ein Wandern des Niederhalters von der Fahrschiene weg verhindern, nicht erforderlich sind. Ergänzend kann jedoch vorgesehen sein, daß der Niederhalter in seinem fußabgewandten Bereich an einem von der Unterlageplatte ausgehenden Anschlag anliegt. Dabei kann der Niederhalter in seinem fußabgewandten Bereich zusätzlich von einer zweiten Sicherung abgedeckt sein, so daß nicht nur ein Wegwandern von der Schiene, sondern auch ein Anheben ausgeschlossen ist. Gleiches bewirkt im übrigen für das erste Sicherungselement.The fuse or an L-shaped or having an equivalent geometry securing element and the recess of the hold-down are matched to one another in such a way that the hold-down can move exclusively or essentially exclusively in the longitudinal direction of the rail, so that additional safeguards that prevent the Prevent hold-down devices away from the running rail, are not required. In addition, however, it can be provided that the hold-down device rests in its area facing away from the foot against a stop extending from the base plate. The hold-down device can also be covered in its area facing away from the foot by a second securing device, so that not only wandering away from the rail, but also lifting is excluded. The same also applies to the first securing element.

Insbesondere kann das zweite schienenabgewandt verlaufende Sicherungselement ein Abschnitt des Anschlags selbst sein bzw. durch eine Ausarbeitung in der Unterlageplatte ausgebildet werden.In particular, the second securing element running away from the rail can be a section of the stop itself or can be formed by elaboration in the base plate.

Ist durch das erste Sicherungselement ein Verschieben des Niederhalters in einer Richtung der Fahrschiene unterbunden, so ist ein Verschieben in die andere Richtung möglich, um den Niederhalter einsetzen bzw. entfernen zu können.If displacement of the hold-down device in one direction of the travel rail is prevented by the first securing element, displacement in the other direction is possible in order to be able to insert or remove the hold-down device.

Um nach dem Einsetzen und ordnungsgemäßen Positionieren des Niederhalters ein Verstellen auszuschließen, kann der Freiraum zwischen dem ersten Sicherungselement und der von der Oberfläche des Niederhalters ausgehenden Durchbrechung mit einem Einsatz ausgefüllt werden. Aber auch dann, wenn dieser nicht vorhanden ist, wird ein unkontrolliertes Verschieben bereits nach kurzer Benutzungsdauer dadurch unterbunden, daß sich Schmutz in der Ausnehmung ablagern kann. Eine Säuberung ist jedoch nur dann erforderlich, wenn eine der entlang der Innenseiten der Seitenstützen bzw. - wangen des Radlenkerständers verlaufenden Stabfederelement entfernt sein sollte. Ansonsten ist ein Verschieben zusätzlich dadurch ausgeschlossen, daß die Erstreckung der Stabfedern und des Niederhalters in Längsrichtung der Fahrschiene insgesamt in etwa dem Abstand zwischen den Seitenstützen entspricht. Hierdurch ergibt sich der Vorteil, daß auch dann, wenn eines der Federelemente brechen sollte, ein unkontrolliertes Verschieben des Niederhalters ausgeschlossen ist.In order to rule out an adjustment after inserting and properly positioning the hold-down device, the space between the first securing element and the opening emerging from the surface of the hold-down device can be adjusted with a Be filled out. But even if this is not available, an uncontrolled shifting is prevented after a short period of use by the fact that dirt can accumulate in the recess. However, cleaning is only necessary if one of the rod spring elements running along the inner sides of the side supports or cheeks of the wheel handlebar stand should be removed. Otherwise a shift is additionally ruled out in that the extension of the bar springs and the hold-down device in the longitudinal direction of the travel rail corresponds approximately to the distance between the side supports. This has the advantage that even if one of the spring elements should break, an uncontrolled displacement of the hold-down device is excluded.

Da die Stabfedern entlang der Innenseiten der Wangen verlaufen, gehen von diesen zumindest die fußseitigen vorderen Widerlager aus. Um dennoch ein einfaches Einbringen bzw. Entfernen des Niederhalters sicherzustellen, weist dieser an einer Längsseite eine Aussparung auf, die den Abmessungen eines der vorderen Widerlager angepaßt ist, so daß eim Verschieben des Niederhalters in Richtung des Widerlagers nicht behindert wird. Auch besteht die Möglichkeit, daß der Niederhalter im Bereich einer der wangenseitigen Widerlager mit seinem Rand versetzt verläuft.Since the bar springs run along the inside of the cheeks, at least the front abutments on the foot side start from them. In order to ensure easy insertion or removal of the hold-down device, it has a recess on one long side that is adapted to the dimensions of one of the front abutments, so that the hold-down device is not obstructed from moving in the direction of the abutment device. There is also the possibility that the hold-down device is offset with its edge in the region of one of the cheek-side abutments.

Durch die erfindungsgemäße Lehre wird ein Niederhalter zur Verfügung gestellt, der selbst auf einfache Weise gesichert werden kann, wobei zusätzlich der Vorteil gegeben ist, daß nur geringe Abmessungen benötigt werden. So kann der Niederhalter quer zur Längsrichtung der Schiene eine Erstreckung aufweisen, die in etwa der Breite der Schiene oder kleiner als diese ist.The teaching according to the invention provides a hold-down device which can itself be secured in a simple manner, with the additional advantage that only small dimensions are required. For example, the hold-down device can have an extension transverse to the longitudinal direction of the rail, which is approximately the width of the rail or smaller than this.

In den Figuren ist eine sogenannte innere Fahrschienenverspannung zum Niederhalten einer Fahrschiene 10 dargestellt, die auf einer Rippenplatte 12 befestigt und niedergehalten ist. Der Fahrschiene 10 ist ein nicht dargestellter Radlenker zugeordnet, der von einem Stützbock oder Radlenkerständer ausgeht, der zwei parallel zueinander verlaufenden Seitenstützen oder -wangen 14 und 16 aufweist, die ihrerseits von der Rippenplatte 12 ausgehen. Insoweit wird auf bekannte Konstruktionen verwiesen, genauso wie in bezug auf die Sicherung der Fahrschiene 10 auf der dem Radlenker abgewandten Seiten ihres Fußes 15, auf den ein nicht dargestellter Spannbügel aufliegen kann.In the figures, a so-called inner rail bracing for holding down a rail 10 is shown, which is fastened and held down on a ribbed plate 12. The travel rail 10 is associated with a wheel handlebar (not shown) which starts from a support bracket or wheel handlebar stand which has two side supports or cheeks 14 and 16 which run parallel to one another and which in turn originate from the ribbed plate 12. In this regard, reference is made to known constructions, as well as in relation to securing the travel rail 10 on the side of its foot 15 facing away from the wheel control arm, on which a tensioning bracket (not shown) can rest.

Auf dem radlenkerseitigen Bereich wird der Fuß 15 von einem als plattenförmiges Element ausgebildeten Niederhalter 18 gesichert, der mit seinem vorderen Bereich 20 auf dem Schienenfuß 15 aufliegt und diesen gegen ein Kippen sichert.On the area on the wheel handlebar, the foot 15 is secured by a hold-down 18 designed as a plate-shaped element, which rests with its front area 20 on the rail foot 15 and secures it against tipping.

Der Niederhalter 18 wird über zwei Stabfederelemente 24, 26 gesichert, die sich entlang der Innenseiten der Wangen 14 und 16 erstrecken und über von der Rippenplatte 12 ausgehende erste Widerlager 28, 30, von den Wangen 14 und 16 ausgehende zweite Widerlager 32, 34 sowie von dem Niederhalter 18 ausgehende Auflager 36, 38 spannbar sind.The hold-down device 18 is secured by two rod spring elements 24, 26 which extend along the inner sides of the cheeks 14 and 16 and via first abutments 28, 30 starting from the ribbed plate 12, second abutments 32, 34 starting from the cheeks 14 and 16 and from the downholder 18 outgoing supports 36, 38 can be tensioned.

Die stabförmigen Federelemente 24, 26 verlaufen oberhalb der zur Schiene 10 fernliegenden ersten Widerlager 28, 30 und unterhalb der vorderen wangenseitigen zweiten Widerlager 32, 34, um sodann auf den im Bereich des vorderen Randbereichs 20 des Niederhalters 18 vorhandenen Auflagern 36, 38 aufzuliegen, die - wie die zeichnerische Darstellung verdeutlicht - abschnittsweise oberhalb des Schienenfußes 15 verlaufen. Dabei stützt sich jedes Stabfederelement 24, 26 derart auf dem Auflager 36, 38 ab, daß unabhängig von der Erstreckung des Niederhalters 18 quer zur Längsrichtung der Schiene 10 dieser nicht kippen kann. Vorzugsweise stützt sich daher die Stabfeder 24, 26 in dem zur Schiene 10 fernliegenden Bereich 40 des Auflagers 36, 38 ab.The rod-shaped spring elements 24, 26 run above the first abutments 28, 30 remote from the rail 10 and below the front cheek-side second abutments 32, 34, in order to then rest on the supports 36, 38 which are present in the region of the front edge region 20 of the hold-down device 18 - As the drawing shows - run in sections above the rail base 15. Each rod spring element 24, 26 is supported on the support 36, 38 in such a way that, regardless of the extent of the hold-down device 18, it cannot tilt transversely to the longitudinal direction of the rail 10. The rod spring 24, 26 is therefore preferably supported in the region 40 of the support 36, 38 that is remote from the rail 10.

Damit der Niederhalter 18 nicht von dem Schienenfuß 15 wegwandern kann, geht von der Rippenplatte 12 ein Anschlag 42 aus, an dem ein Längsrand 44 des Niederhalters 18 anliegt. Von diesem Rand 44 geht ein Abschnitt 46 aus, der sich innerhalb einer Ausarbeitung der Rippenplatte 12 bzw. des Anschlages 42 erstreckt und zumindest teilweise abgedeckt ist, so daß ein Abheben des Niederhalters 18 ausgeschlossen ist. Die diesbezügliche Konstruktion bildet eine Sicherung 47, die als zweite Sicherung bezeichnet wird.So that the hold-down device 18 cannot move away from the rail foot 15, a stop 42 extends from the rib plate 12, against which a longitudinal edge 44 of the hold-down device 18 rests. A section 46 extends from this edge 44, which extends within a preparation of the ribbed plate 12 or the stop 42 and is at least partially covered, so that the holding-down device 18 cannot be lifted off. The relevant construction forms a fuse 47, which is referred to as a second fuse.

Auch im fußseitigen Bereich ist eine (erste) Sicherung 48 vorgesehen, die ein Anheben des Niederhalters 18 ausschließt. So weist der Niederhalter 18 in seinem fußseitigen Bereich eine Aussparung 50 mit einem Abschnitt 52 auf, der quer zur Längsrichtung der Schiene verläuft und innere Begrenzung 53 der Aussparung 50 bildet. Der Abschnitt 52 wird sodann von einem Abschnitt 54 der Rippenplatte 12 bzw. einem von diesem ausgehenden Steg, der gleichzeitig einen Anschlag 55 für den Schienenfuß 15 bildet, überdeckt.A (first) safety device 48 is also provided in the foot area, which prevents the hold-down device 18 from being lifted. The hold-down device 18 thus has a recess 50 in its foot-side region with a section 52 which runs transversely to the longitudinal direction of the rail and forms the inner boundary 53 of the recess 50. The section 52 is then covered by a section 54 of the rib plate 12 or a web extending from it, which at the same time forms a stop 55 for the rail foot 15.

Erfindungsgemäß wirken auf den Niederhalter 18 die Sicherungen 47, 48, die ein Abheben des Niederhalters 18 ausschließen. Gleichzeitig ist durch den Verlauf bzw. die Ausbildung der einander zugeordneten Abschnitte einerseits des Niederhalters 18 und andererseits der Ausarbeitungen sowohl des Anschlags 44 als auch des Anschlags 54 bzw. der Rippenplatte 12 sichergestellt, daß ein Wandern des Niederhalters 18 in einer Richtung entlang der Schiene 10 ausgeschlossen ist, und zwar im Ausführungsbeispiel der Fig. 1 in die Zeichenebene hinein. In die entgegengesetzte Richtung muß ein Verschieben möglich sein, nämlich dann, wenn der Niederhalter 18 eingebracht bzw. entfernt werden soll. Damit in diesem Fall das nach innen ragende und von der Wange 16 des Stützbocks ausgehende Widerlager 32 eine Behinderung nicht darstellt, weist der Niederhalter 18 in diesem Bereich eine weitere Aussparung 56 auf, innerhalb der sich das Widerlager 32 dann erstreckt, wenn der Niederhalter 18 in Ausgriff mit den Sicherungen 47, 48 gelangt und angehoben werden soll. Voraussetzung hierfür ist selbstverständlich, daß die Stabfedern 24, 26 zuvor gelöst bzw. entfernt worden sind.According to the invention act on the hold-down device 18, the fuses 47, 48, which prevent the hold-down device 18 from being lifted off. At the same time, the course or the formation of the mutually assigned sections of the hold-down device 18 on the one hand and the elaborations of both the stop 44 and the stop 54 or the ribbed plate 12 ensure that the hold-down device 18 moves in one direction along the rail 10 is excluded, in the embodiment of FIG. 1 into the drawing plane. Moving in the opposite direction must be possible, namely when the hold-down device 18 is to be inserted or removed. So that in this case the inwardly projecting abutment 32 starting from the cheek 16 of the support frame does not constitute a hindrance, the hold-down device 18 has a further recess 56 in this area, within which the abutment 32 extends when the hold-down device 18 is in Access reached with fuses 47, 48 and should be raised. The prerequisite for this is, of course, that the bar springs 24, 26 have been loosened or removed beforehand.

Alternativ besteht die Möglichkeit, daß der Niederhalter 18 fußseitig geschlossen ist (gestrichelter Bereich 58). Der Randbereich 58 begrenzt sodann die Ausnehmung 50, in die die erste Sicherung 48 bzw. der Abschnitt 54 des Anschlags 55 eingreift. Da in diesem Fall der gestrichelte Bereich 58 schienenabgewandt an dem Abschnitt 54 anliegt, der somit als Anschlag wirkt, erübrigt sich der hintere Anschlag 42, so daß infolgedessen der Niederhalter 18 an der schienenabgewandten äußeren Kante 60 des Abschnitts 54 enden könnte. Hierdurch ergibt sich eine noch kürzere und kompaktere Baueinheit.Alternatively, there is the possibility that the hold-down device 18 is closed on the foot side (dashed area 58). The edge region 58 then delimits the recess 50, in which engages the first fuse 48 or the section 54 of the stop 55. In this case, since the dashed area 58 abuts the section 54 facing away from the rail, which thus acts as a stop, the rear stop 42 is unnecessary, so that the hold-down device 18 could end at the outer edge 60 of the section 54 facing away from the rail. This results in an even shorter and more compact unit.

Eine entsprechende Konstruktion ist den Fig. 3 und 4 zu entnehmen. Insbesondere aus der Draufsicht gemäß Fig. 4 wird erkennbar, daß der Niederhalter 18 quer zur Längsrichtung der Schiene 10 überaus kurz ausgebildet sein kann, ohne daß die Gefahr besteht, daß der Niederhalter 18 unkontrolliert kippen bzw. wandern kann. Gleichzeitig ist jedoch sichergestellt, daß die Schiene 10 im erforderlichen Umfang niedergehalten wird.A corresponding construction can be seen in FIGS. 3 and 4. In particular, from the top view according to FIG. 4 it can be seen that the holding-down device 18 can be made extremely short transversely to the longitudinal direction of the rail 10, without the risk that the holding-down device 18 can tilt or move in an uncontrolled manner. At the same time, however, it is ensured that the rail 10 is held down to the required extent.

Wie insbesondere die Draufsicht der Fig. 4 erkennen läßt, weist der Niederhalter 18 eine in Längsrichtung der Fahrschiene 10 verlaufende in Draufsicht ovale Aussparung 50 auf, die von dem im Schnitt eine L-förmige Geometrie aufweisenden Sicherungselement 54 durchsetzt ist, dessen Längsschenkel senkrecht von der Unterlageplatte 12 ausgeht und dessen Querschenkel sich parallel zur Längsrichtung der Fahrschiene 10 erstreckt. Dabei weist der Querschenkel 55 eine Außengeometrie auf, die beispielsweise der der Durchbrechung bzw. Aussparung 50 entspricht, um ein weitgehend flächiges Anliegen sowohl im Stirnbereich 57 als auch entlang der Längsseiten 59 und 61 zu ermöglichen. Hierdurch wird zusätzlich sichergestellt, daß ein unkontrolliertes Verschieben des Niederhalters 18 unterbleibt.As can be seen in particular from the top view of FIG. 4, the hold-down device 18 has a recess 50 which runs in the longitudinal direction of the travel rail 10 and which is oval in plan view and which is penetrated by the securing element 54 having an L-shaped geometry in section, the longitudinal leg of which is perpendicular to the Base plate 12 extends and the cross leg extends parallel to the longitudinal direction of the travel rail 10. The cross leg 55 has an outer geometry which corresponds, for example, to the opening or cutout 50 in order to allow a largely flat contact both in the end region 57 and along the longitudinal sides 59 and 61. This additionally ensures that the hold-down device 18 is not moved in an uncontrolled manner.

Der bei ordnungsgemäß positioniertem Niederhalter 18 zwischen dem Querschenkel 55 und der Aussparung 50 verbleibende Oberflächenbereich 63 kann mit einem nicht dargestellten Einsatz ausgefüllt sein, um zusätzlich ein Wandern zu verhindern. Beim Fehlen eines Einsatzes können Schmutzablagerungen eine gleiche Funktion ausüben.The surface area 63 remaining between the cross leg 55 and the recess 50 when the hold-down device 18 is properly positioned can be filled with an insert (not shown) in order to additionally prevent migration. In the absence of an insert, dirt deposits can have the same function.

Ferner erkennt man aus der Schnittdarstellung gemäß Fig. 3, daß der Niederhalter 18 im Schnitt eine keilförmige Geometrie aufweist und zum einen in seinem fußabgewandten Querrandbereich 66 und zum anderen im Bereich der Auflager 36, 38 abgestützt ist, wodurch zusätzlich ein Kippen aufgrund von Unebenheiten der Unterlageplatte 12 bzw. des Schienenfußbereichs im Vergleich zu einem flächig aufliegenden Niederhalter ausgeschlossen wird.3 that the holding-down device 18 has a wedge-shaped geometry in section and is supported on the one hand in its transverse edge region 66 facing away from the foot and on the other hand in the region of the supports 36, 38, which additionally prevents tilting due to unevenness in the base plate 12 or the rail foot area compared to a flat hold-down device.

Die Draufsicht der Fig. 4 zeigt des weiteren, daß der Niederhalter 18 im Bereich des Widerlagers 32 einen Absatz 68 aufweist, um ein Verschieben in Schienenlängsrichtung dann zu ermöglichen, wenn der Niederhalter 18 eingesetzt bzw. entfernt werden soll.The top view of FIG. 4 further shows that the hold-down device 18 has a shoulder 68 in the area of the abutment 32, in order to enable displacement in the longitudinal direction of the rail when the hold-down device 18 is to be inserted or removed.
