- a hold-down device is provided by the teaching according to the invention can be secured in a simple manner, with the additional advantage being given is that only small dimensions are required. So the hold-down can cross to Longitudinal direction of the rail have an extension that is approximately the width of the Rail or less than this.
- a so-called inner rail bracing for holding down a running rail 10 shown, which is fastened and held down on a ribbed plate 12 is.
- the running rail 10 is associated with a wheel arm, not shown, which starting from a support frame or wheel handlebar stand, the two parallel to each other Side supports or cheeks 14 and 16, which in turn by the Go out ribbed plate 12.
- the foot 15 is shaped as a plate Element designed hold-down 18 secured with its front portion 20th rests on the rail foot 15 and secures it against tipping.
- the hold-down device 18 is secured by two rod spring elements 24, 26 which run along of the inside of the cheeks 14 and 16 and over from the rib plate 12th outgoing first abutments 28, 30, outgoing from the cheeks 14 and 16 second Abutments 32, 34 and supports 36, 38 extending from the hold-down device 18 can be tensioned are.
- the rod-shaped spring elements 24, 26 run above those remote from the rail 10 first abutment 28, 30 and below the front cheek-side second Abutment 32, 34 to then on the in the region of the front edge region 20 of the Hold down 18 existing supports 36, 38, which - like the drawing Illustration clarifies - run in sections above the rail foot 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 transversely to the longitudinal direction of the Rail 10 this cannot tilt.
- the rod spring 24 is therefore preferably supported, 26 in the area 40 of the support 36, 38 remote from the rail 10.

Moving in the opposite direction is necessary be possible, namely when the hold-down device 18 is inserted or should be removed.
- the Hold-down device 18 in this area has a further recess 56 within which the abutment 32 extends when the hold-down device 18 is in engagement with the Fuses 47, 48 arrives and is to be raised.
- the prerequisite for this is of course, that the bar springs 24, 26 have been loosened or removed beforehand.
- 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.
- the dashed area 58 facing away from the rail on the section 54 is present, which thus acts as a stop, the rear stop 42 is unnecessary, so that as a result, the hold-down device 18 on the outer edge 60 of the rail remote from the Section 54 could end. This results in an even shorter and more compact one Unit.
- FIGS. 3 and 4 A corresponding construction can be seen in FIGS. 3 and 4. Especially from 4 shows that the hold-down device 18 is transverse to the longitudinal direction the rail 10 can be made extremely short without the risk there is that the hold-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 becomes.
- the hold-down device 18 has an oval recess running in the longitudinal direction of the running rail 10 in plan view 50 on that of the securing element having an L-shaped geometry in section 54 is penetrated, the longitudinal leg of which is perpendicular to the base plate 12 goes out and the cross leg parallel to the longitudinal direction of the rail 10th extends.
- the cross leg 55 has an external geometry, for example which corresponds to the opening or recess 50 by a largely flat Bearing both in the end region 57 and along the long sides 59 and 61 enable. This also ensures that uncontrolled movement of the hold-down device 18 is omitted.
- the hold-down device 18 in the Cut has a wedge-shaped geometry and on the one hand in its foot-facing Transverse edge area 66 and on the other hand is supported in the area of supports 36, 38, whereby additionally tilting due to unevenness of the base plate 12 or of the rail foot area in comparison to a flat hold-down device is excluded.

Abstract
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 a running track with an associated one starting from a support frame or a wheel handlebar stand Wheel handlebars, encompassing themselves between a base - like ribbed plate outgoing side supports or cheeks of the wheel handlebar stand extending plate-shaped element as well as a spring element that rests between supports and abutments is exciting, 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. Thereby forms the plate-shaped element referred to as the base plate with the side supports is one unit. The rail itself is held down by the spring element, which in a Recess is slidable, which extends in the base plate. The recess points a formation causing the tension of the spring element. Breaks the spring element, projections of the footplate act as additional tilt protection for the rail foot. Detached from this, however, is the introduction or removal of a U-shaped one Geometric spring element expensive. Dirt can also accumulate in the Deposit recess that make it difficult or even difficult to replace the spring element to make impossible.
Der vorliegenden Erfindung liegt das Problem zugrunde, eine Vorrichtung der zuvor genannten Art 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 a device of the aforementioned Art in such a way that even in confined spaces a safe The rail can be held down. At the same time, it should be ensured that Defined force is applied to the foot of the rail 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 attachable to the base plate by means of the spring element and as a hold-down for the rail foot is supported on this that the spring element to a first, which extends in some areas over the rail foot Section of the plate-shaped element is supported as a support and that of the base plate a first fuse runs out, which penetrates the hold-down and from this is covered in some areas. In particular, two are designed as bar springs Spring elements are provided to secure the hold-down device, which extends along the long sides of the hold-down device and parallel on the inside along the side supports or cheeks of the wheel handlebar 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) go 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 via two indirectly or directly from a base plate outgoing abutment is clamped, it is only necessary that the The downholder holding down the rail foot has a support so that the extension of the hold-down device can be selected to be extremely short transversely to the longitudinal direction of the rail can. The spring element acts on the support such that the hold-down itself not unstable, i.e. it can tip over, but rather forces in the rail foot like this initiates that this is held down to the extent necessary.
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 the sake of simplification of a plate-shaped element is spoken, about which the rail is held down, another can Geometry can be chosen, it is irrelevant how the surface of the plate-shaped Element is formed because 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 one also the function of a hold-down slide, such as this z. B. the DE 42 29 014 A 1 or DE 41 12 926 A1 can be seen, also the support outside of the rail foot runs, so that there may be unfavorable leverage in the Can form 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 fuse in section an L-shaped geometry with perpendicular from the base plate protruding longitudinal leg and parallel to the base plate Has cross leg that runs above a portion of the hold-down. Here the cross leg can be flush on the outside with the surface of the hold-down device or in this run in.
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 equivalent geometry The securing element and the cut-out of the hold-down device are one on the other agreed that the hold-down device is exclusively or essentially exclusively can move in the longitudinal direction of the rail, so that additional safeguards, that do not prevent the hold-down from moving away from the running rail required are. In addition, it can be provided that the hold-down in its area facing away from the foot at a stop extending from the base plate is present. The hold-down can also be used in the area facing away from the foot be covered by a second fuse, so that not only wandering away from the rail, but also lifting is excluded. The same effect otherwise for 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 attack itself or by elaborating in the base plate be formed.
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.Is the first securing element moving the hold-down device in one direction the rail is prevented from moving in the other direction possible 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 ein 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.To put in after the insertion and proper positioning of the hold-down Exclude adjustment, the space between the first securing element and the opening from the surface of the holding-down device with a Be filled out. But even if this does not exist, a uncontrolled moving is prevented after a short period of use, that dirt can accumulate in the recess. However, a purge is only required if one of the along the inner sides of the side supports or - cheek of the Radlenkerstand extending rod spring element should be removed. Otherwise a shift is additionally excluded in that the extension the rod springs and the hold-down device in the longitudinal direction of the travel rail as a whole in corresponds approximately to the distance between the side supports. This results in the Advantage that even if one of the spring elements should break, an uncontrolled one Moving 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 ein 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 go from them the front abutments on the foot side. To make it easy to insert to ensure that the hold-down device is removed or removed, it has one on one long side Recess that is adapted to the dimensions of one of the front abutments, so that moving the hold-down in the direction of the abutment does not hinder becomes. There is also the possibility that the hold-down device in the area of one of the cheek-side Abutment runs offset with its edge.
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.A hold-down device is provided by the teaching according to the invention can be secured in a simple manner, with the additional advantage being given is that only small dimensions are required. So the hold-down can cross to Longitudinal direction of the rail have an extension that is approximately the width of the Rail or less 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 running
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
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
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-
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
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)
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, fuses 47, 48 act on hold-down
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
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. Especially from
4 shows that the hold-down
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
