Definitions

  • the traffic flows often have to be diverted in a route that deviates from the usual course of the road.
  • the remaining lane width is usually too small to separate the traffic flows flowing in opposite directions from one another by wider lane strips with lane dividers of greater height or with blocking beacons.
  • Guidance devices of lower overall height are mostly used there. Even where roadway dividers or barrier beacons of greater height could be set up, guiding devices with a lower height are often preferred, since the visual tunnel effect of the higher roadway dividers or closely spaced beacon stands, which is psychologically unfavorable for the vehicle driver, is significantly reduced.

PCT No. PCT/EP93/00237 Sec. 371 Date Jul. 29, 1994 Sec. 102(e) Date Jul. 29, 1994 PCT Filed Feb. 2, 1993 PCT Pub. No. W093/15275 PCT Pub. Date Aug. 5, 1993.The traffic barrier used in guidance installations has a longitudinal shape and on its upper surface a first part of a coupling device. A second part is provided on a guide body coupling the same to the traffic barrier. On each end the traffic barrier is provided with parts divided from a further coupling device so that the traffic barrier can be coupled to a neighboring traffic barrier in a longitudinal direction. The traffic barrier has a cross-section wherein the outline of the side walls and the upper wall is contiguous with a circumferential curve being at least almost constant in its outline and being substantially convex in its outline but can extend linearly in a side wall area which is adjacent an under side of the barrier until encountering a point of contact of a tangent in the convex area. A step off-set relative to the circumferential curve has been provided in the area of each side wall which off-set in its lower area forms an edge at the circumferential curve and in its upper area is at least almost curved constantly and merges into the circumferential curve.

Description

An Straßenbaustellen, insbesondere an Baustellen von Fernstraßen und Autobahnen, müssen die Verkehrsströme häufig in einer vom üblichen Fahrbahnverlauf abweichenden Streckenführung vorbeigeleitet werden. Meist ist die verbleibende Fahrbahnbreite zu gering, um die einander entgegengesetzt fließenden Verkehrsströme durch breitere Fahrbahnstreifen mit Fahrbahnteilern größerer Höhe oder mit Absperrbaken voneinander zu trennen. Dort werden meist Leiteinrichtungen von geringerer Bauhöhe verwendet. Auch dort, wo Fahrbahnteiler oder Absperrbaken größerer Höhe aufgestellt werden könnten, werden häufig Leiteinrichtungen mit geringerer Höhe bevorzugt, da bei ihnen die für die Fahrzeuglenker psychologisch ungünstige visuelle Tunnelwirkung der höheren Fahrbahnteiler oder dicht aufeinanderfolgender Bakenständer wesentlich verringert ist.At road construction sites, especially at construction sites of highways and highways, the traffic flows often have to be diverted in a route that deviates from the usual course of the road. The remaining lane width is usually too small to separate the traffic flows flowing in opposite directions from one another by wider lane strips with lane dividers of greater height or with blocking beacons. Guidance devices of lower overall height are mostly used there. Even where roadway dividers or barrier beacons of greater height could be set up, guiding devices with a lower height are often preferred, since the visual tunnel effect of the higher roadway dividers or closely spaced beacon stands, which is psychologically unfavorable for the vehicle driver, is significantly reduced.

Bei einer bekannten Leiteinrichtung mittlerer Höhe (DE-U-89 15 303.0 (bzw. EP-A-0 380 062) sind Fußschwellen mit einem langgestreckten quaderförmigen oder prismatischen Grundkörper vorhanden, auf deren Oberseite mittels einer Kupplungsvorrichtung je ein haubenartiger Leitkörper angeordnet werden kann. Diese Fußschwellen lassen sich zu einer ununterbrochenen Reihe aneinander anschließen, und zwar mit Hilfe einer weiteren Kupplungsvorrichtung, deren Teile in zwei Gruppen aufgeteilt sind, von denen je eine Gruppe an je einer der Stirnseiten der Fußschwellen angeordnet ist. Damit lassen sich die Fußschwellen sowohl in Längsrichtung als auch in Querrichtung formschlüssig miteinander kuppeln. Diese Leiteinrichtung wird vor allem entlang der Trennungslinie zweier Fahrbahnen mit Gegenverkehr verlegt. Die Erfahrung hat gezeigt, daß nur in stark gekrümmt verlaufenden Übergangsstrecken jede der Fußschwellen mit einem haubenartigen Leitkörper versehen sein muß. Bei geradem Streckenverlauf genügt es im allgemeinen, die Leitkörper im Abstand von etwa drei bis fünf Metern anzuordnen, d.h. nur jede dritte bis fünfte Fußschwelle mit einem Leitkörper zu bestücken.In a known guide device of medium height (DE-U-89 15 303.0 (or EP-A-0 380 062), foot sleepers with an elongated cuboid or prismatic base body are provided, on the top of which a hood-like guide body can be arranged by means of a coupling device. These foot sleepers can be connected to one another in an uninterrupted row, with the aid of a further coupling device, the parts of which are divided into two groups, one group of which is arranged on one of the end faces of the foot sleepers as well as form-fitting coupling in the transverse direction is mainly laid along the dividing line of two lanes with oncoming traffic. Experience has shown that only in strongly curved transition sections must each of the foot sleepers be provided with a hood-like guide body. If the route is straight, it is generally sufficient to arrange the guide bodies at a distance of approximately three to five meters, that is to say to only fit one guide body every third to fifth foot threshold.

Die Fußschwellen haben eine Länge von etwa einem Meter, eine Höhe zwischen 70 und 100 mm und an ihrer Unterseite im allgemeinen eine Breite von ca. 250 mm. Im Bereich ihrer Oberseite sind die Fußschwellen schmäler als im Bereich ihrer Unterseite. Die Querschnittsform der Fußschwellen hat demnach im Bereich der Seitenwände einen von unten nach oben der Mitte sich annähernden Verlauf. An der Übergangsstelle zur Unterseite befindet sich ein lotrecht verlaufender Abschnitt der Umrißlinie des Querschnittes, dessen Höhe zwischen 15 auf 25 mm liegt. Daran schließt ein konvex gekrümmter Abschnitt mit verhältnismäßig kleinem Krümmungsradius an. Darauf folgt ein konkav gekrümmter Abschnitt mit geringerer Krümmung, an den wiederum ein konvex gekrümmter Abschnitt mit größerer Krümmung anschließt, der in den geraden und waagerechten Abschnitt der Oberseite übergeht.The foot sleepers have a length of about one meter, a height between 70 and 100 mm and generally a width of about 250 mm on their underside. The foot sills are narrower in the area of their top than in the area of their bottom. The cross-sectional shape of the foot sleepers accordingly has a course in the region of the side walls which approaches from bottom to top of the center. At the transition point to the underside there is a perpendicular section of the outline of the cross section, the height of which is between 15 and 25 mm. This is followed by a convexly curved section with a relatively small radius of curvature. This is followed by a concavely curved section with a lesser curvature, which in turn is followed by a convexly curved section with a larger curvature, which merges into the straight and horizontal section of the upper side.

Die verhältnismäßig geringe Höhe der Fußschwelle ermöglicht es, daß ein in nicht zu spitzem Winkel auf die Fußschwelle zurollendes Fahrzeugrad verhältnismäßig leicht auf die Fußschwelle hinaufrollen und über sie hinwegrollen kann, ohne daß dabei das Fahrzeug in merklichem Maße aus seiner Fahrtrichtung abgelenkt wird. Der geschilderte Verlauf der Querschnittsfläche im Bereich der Seitenwände soll dieses Hinaufrollen und darüber Hinwegrollen des betreffenden Fahrzeugrades zusätzlich erleichtern. Dadurch bleibt ein etwa aus Unachtsamkeit mit den Rändern einer Fahrzeugseite über die Fußschwelle hinwegrollendes Fahrzeug für den Fahrer beherrschbar, der es ebenso leicht wieder auf die richtige Seite der Fußschwelle zurücklenken kann, ohne daß dabei Schleudervorgänge allein aufgrund des Überrollvorganges zu befürchten sind.The relatively low height of the foot sill enables a vehicle wheel that rolls towards the foot sill at a not too acute angle to roll up and roll over the foot sill relatively easily without the vehicle being distracted to any significant extent from its direction of travel. The described course of the cross-sectional area in the region of the side walls is intended to additionally facilitate this rolling up and rolling away of the vehicle wheel in question. This leaves you with carelessness with the edges one side of the vehicle over the threshold can be controlled by the driver, who can just as easily steer it back to the right side of the threshold without fear of skidding solely due to the rollover process.

Wenn die Räder einer Fahrzeugseite in einem sehr spitzen Winkel auf die Fußschwelle zurollen, sie die Fußschwelle gewissermaßen anstreifen, kann es vorkommen, daß die infolge der elastischen Verformung des Reifenquerschnittes ausgebauchte Reifenflanke bereits gegen den im Querschnitt konkav gekrümmten mittleren und oberen Abschnitt der Seitenwand der Fußschwelle anläuft, noch ehe die Lauffläche des Reifens auf den unteren Abschnitt der Seitenwand der Fußschwelle aufgelaufen ist. Dadurch wird nicht zuletzt wegen des spitzen Anfahrwinkels auf die Fußschwelle eine beträchtliche Seitenkraft ausgeübt, die wegen der fehlenden Beschwerung der Fußschwelle durch die Radlast dazu führen kann, daß die Fußschwelle um ein gewisses Maß zur Seite geschoben wird. Wenn an diesem Anstreifvorgang gleich mehrere Fahrzeugräder beteiligt sind, etwa diejenigen eines Zugfahrzeuges mit Anhänger, kann diese seitliche Verschiebung ein Ausmaß annehmen, das die jenseits der Leiteinrichtung verlaufende Fahrbahn merklich einengt. Aufgrund der Abweichung der Leiteinrichtung aus der vorgegebenen gestreckten Linienführung kann das zu Irritationen der Verkehrsteilnehmer führen, und zwar, insbesondere auf derjenigen Seite der Leiteinrichtung, nach der hin die Leiteinrichtung bogenförmig verschoben ist.If the wheels of one side of the vehicle roll towards the foot sill at a very acute angle, they touch the foot sill to a certain extent, it can happen that the flank of the tire bulges as a result of the elastic deformation of the tire cross section already against the concave curved middle and upper section of the side wall of the foot sill starts before the tread of the tire hits the lower portion of the sidewall of the sill. As a result, not least because of the acute approach angle to the foot sill, a considerable lateral force is exerted which, because of the lack of weight on the foot sill due to the wheel load, can result in the foot sill being pushed aside to a certain extent. If several vehicle wheels are involved in this rubbing operation, for example those of a towing vehicle with a trailer, this lateral displacement can take on an extent that noticeably narrows the roadway beyond the guide device. Due to the deviation of the guidance device from the predetermined straight line, this can lead to irritation of the road users, in particular on the side of the guidance device towards which the guidance device is displaced in an arc.

Der Erfindung liegt die Aufgabe zugrunde, eine Fußschwelle für Leiteinrichtungen und dergleichen zu schaffen, bei der die Gefahr zumindest vermindert wenn nicht gar beseitigt ist, daß sie durch anstreifende Fahrzeugräder zur Seite geschoben wird.The invention has for its object to provide a threshold for control devices and the like, in which the risk is at least reduced, if not eliminated, that it is pushed aside by rubbing vehicle wheels.

Diese Aufgabe wird mit den im Anspruch 1 angegebenen Merkmalen gelöst.This object is achieved with the features specified in claim 1.

Dadurch, daß die Hüllkurve der Querschnittsform der Fußschwelle einen zumindest annähernd stetigen Verlauf hat, der allenfalls in dem an die Unterseite anschließenden unteren Abschnitt des Seitenwandbereiches und in dem die Oberseite bildenden Abschnitt gerade und im übrigen konvex gekrümmt ist, wird vermieden, daß eine ausgebauchte Reifenflanke die Seitenwände schon früher erreicht als die Reifenschulter den unteren Teil der Seitenwand. Dadurch beginnt das betreffende Fahrzeugrad schon auf die Fußschwelle hinaufzurollen, ehe seine Reifenflanke die Fußschwelle wegschieben kann. Dadurch, daß im Bereich der Seitenwand der Fußschwelle mindestens eine gegenüber der Hüllkurve nach innen abgesetzte Stufe vorhanden ist, wird das Hinaufrollen des Fahrzeugrades auf die Fußschwelle erleichtert, so daß die Fußschwelle praktisch schon mit Beginn des Anstreifens durch das Fahrzeugrad belastet wird und so das Wegschieben verhindert wird. Diese Stufe wirkt gewissermaßen als Kletterstufe für das Fahrzeugrad. Das gilt sowohl für das Hinauf- und Hinüberrollen, wie auch für das Zurückrollen des Fahrzeugrades auf die richtige Fahrbahnseite. Sobald der Reifen mit Hilfe der Kletterstufe(n) wenigstens teilweise die Fußschwelle erklommen hat, wird durch den konvexen weiteren Verlauf der Hüllkurve das vollständige Hinaufrollen zusätzlich erleichtert.The fact that the envelope of the cross-sectional shape of the threshold has an at least approximately continuous course, which is at most in the lower section of the side wall region adjoining the underside and in the section forming the upper side straight and otherwise convexly curved, prevents a bulged tire flank the side walls reach the lower part of the side wall earlier than the tire shoulder. As a result, the vehicle wheel in question begins to roll up onto the threshold before its tire flank can push the threshold away. The fact that in the area of the side wall of the foot sill there is at least one step set inward with respect to the envelope curve, makes it easier for the vehicle wheel to roll up onto the foot sill, so that the foot sill is practically loaded by the vehicle wheel as soon as it is touched and thus pushed away is prevented. This step acts as a climbing step for the vehicle wheel. This applies to rolling up and over as well as rolling the vehicle wheel back to the right side of the road. As soon as the tire has at least partially climbed the threshold with the help of the climbing step (s), the convex further course of the envelope curve makes it even easier to roll up completely.

Bei einer Ausgestaltung der Fußschwelle nach Anspruch 2 wird erreicht, daß der Übergang von der Seitenwand zur Oberseite der Fußschwelle verkürzt wird, so daß die eigentliche Oberseite etwas breiter ausgeführt werden kann. Das kommt der Anordnung und Ausbildung der Kupplungsteile für die aufzusetzenden Leitkörper zugute. Das wird durch eine Weiterbildung der Fußschwelle nach Anspruch 3 unterstützt, wonach die Krümmung der Hüllkurve im Abschnitt der Oberseite stark verringert bis vollständig abgeflacht wird.In one embodiment of the threshold according to claim 2 it is achieved that the transition from the side wall to the top of the threshold is shortened, so that the actual top can be made somewhat wider. This benefits the arrangement and design of the coupling parts for the guide body to be fitted. This is supported by a further development of the threshold according to claim 3, according to which The curvature of the envelope curve in the section of the upper side is greatly reduced until it is completely flattened.

Die aus Fig. 1 ersichtlichen Leiteinrichtungen 10 weisen zumindest je eine Fußschwelle 11 auf. Je nach Bedarf weisen sie auch einen haubenartigen Leitkörper 12 auf, wie es aus Fig. 1 bei der mittleren Leiteinrichtung 10 ersichtlich ist. Ein solcher Leitkörper 12 ist mit der zugeordneten Fußschwelle 11 mittels einer Kupplungsvorrichtung 13 lösbar verbunden. Der an der Oberseite 14 der Fußschwelle 11 angeordnete Teil 13.1 der Kupplungsvorrichtung 13 der in Fig. 1 nur schematisch dargestellt ist, weist als wichtisten Teil eine querverlaufende Ausnehmung 14 auf, deren Aufriß, auf den Kopf gestellt betrachtet, T-förmig ist. Der Leitkörper 12 weist einen Fuß 16 auf, dessen Aufriß auf den Aufriß der Ausnehmung 15 abgestimmt ist. Die für die zugehörigen beiden Rippen des Fußes 16 werden in Fig. 1 von den Teilen der Kupplungsvorrichtung 13.1 verdeckt.The guide devices 10 shown in FIG. 1 each have at least one foot threshold 11. Depending on requirements, they also have a hood-like guide body 12, as can be seen in FIG. 1 in the middle guide device 10. Such a guide body 12 is detachably connected to the associated foot sill 11 by means of a coupling device 13. The part 13.1 of the coupling device 13 which is arranged on the upper side 14 of the threshold 11 and which is only shown schematically in FIG. 1 has, as the most important part, a transverse recess 14, the elevation of which, viewed upside down, is T-shaped. The guide body 12 has a foot 16, the elevation of which is matched to the elevation of the recess 15. Those for the associated two ribs of the foot 16 are covered in FIG. 1 by the parts of the coupling device 13.1.

Jede Fußschwelle 11 weist als Hauptteil einen langgestreckten, zumindest näherungsweise quaderförmigen oder prismatischen Grundkörper 17 auf. Wie aus Fig. 2 bis Fig. 4 ersichtlich ist, sind seine beiden Stirnflächen 18 und 19 zumindest annähernd lotrecht ausgerichtet. Wie insbesondere aus Fig. 3 ersichtlich ist, sind diese beiden Stirnflächen im Grundriß kreisbogenförmig gekrümmt, und zwar die in Fig. 3 linksgelegene Stirnfläche 18 konvex und die in Fig. 3 rechtsgelegene Stirnfläche 19 konkav gekrümmt. Der Krümmungshalbmesser beider Stirnflächen 18 und 19 ist zumindest annähernd gleich, so daß sie eng ineinanderpassen, wenn die Fußschwellen 11 in Längsrichtung aneinandergereiht sind, wie es aus Fig. 1 ersichtlich ist.The main part of each foot sill 11 has an elongated, at least approximately cuboid or prismatic base body 17. As can be seen from FIGS. 2 to 4, its two end faces 18 and 19 are at least approximately perpendicular. As can be seen in particular from FIG. 3, these two end faces are curved in the shape of a circular arc, specifically the end face 18 on the left in FIG. 3 and curved concavely on the end face 19 on the right in FIG. 3. The radius of curvature of the two end faces 18 and 19 is at least approximately the same, so that they fit closely into one another when the foot sleepers 11 are lined up in the longitudinal direction, as can be seen from FIG. 1.

Die Fußschwellen 11 sind mit einer weiteren Kupplungsvorrichtung 21 ausgerüstet, mittels der jede Fußschwelle 11 in ihrer Längsrichtung mit einer benachbarten Längsschwelle formschlüssig gekuppelt werden kann und wieder von ihr getrennt werden kann.The foot sills 11 are equipped with a further coupling device 21, by means of which each foot sill 11 can be positively coupled in its longitudinal direction with an adjacent longitudinal sill and can be separated from it again.

Die Teile der Kupplungsvorrichtung 21 sind am Grundkörper 17 in zwei Gruppen aufgeteilt, von denen die eine Teilegruppe 21.1 an dem einen Endbereich mit der konvex gekrümmten Stirnfläche 18 angeordnet ist und von denen die zweite Teilegruppe 21.2 in dem Endbereich mit der konkav gekrümmten Stirnfläche 19 angeordnet ist.The parts of the coupling device 21 are divided on the base body 17 into two groups, of which the one part group 21.1 is arranged at the one end region with the convexly curved end face 18 and of which the second part group 21.2 is arranged in the end region with the concave curved end face 19 .

Zur Teilegruppe 21.2 gehört ein lotrecht aufwärtsgerichtetes Koppelglied 22, das am Ende eines Haltebügels 23 angeordnet ist. Der Haltebügel 23 ist als Stabstahlabschnitt ausgebildet, dessen einer Endabschnitt zur Bildung des Koppelgliedes 22 rechtwinklig abgewinkelt ist. Am entgegengesetzten Ende des Haltebügels 23 ist der Stabstahl zweimal abgewinkelt, um auf diese Weise ein hakenförmiges Ende zu bilden. Mit diesem Ende ist der Haltebügel bei der Herstellung des Grundkörpers 17 in diesem eingeformt.The parts group 21.2 includes a vertically upward coupling element 22 which is arranged at the end of a holding bracket 23. The bracket 23 is designed as a bar section, one end portion of which is angled at right angles to form the coupling member 22. At the opposite end of the holding bracket 23, the bar steel is angled twice in order to form a hook-shaped end in this way. With this end, the retaining bracket is molded into the base body 17 during manufacture.

Zur Teilegruppe 21.1 gehört eine lotrecht aufwärtsgerichtete Ausnehmung 24 an der Unterseite 25 sowie eine daran anschließende Nut 26. Die Ausnehmung 24 hat ebenso wie das Kuppelglied 22 eine rechteckige Grundrißfläche, die gegenüber der Grundrißfläche des Koppelgliedes nur um so viel größer ist, daß zwischen den beiden Teilen eine gegenseitige Drehbewegung um die Hochachse um bis zu 1° möglich ist. Die Nut 26 ist auf die Form des Haltbügels 23 so abgestimmt, daß der Haltebügel 23 in ihr vollständig Platz hat. Dabei ist die Grundrißfläche der Nut 26 gegenüber der Grundrißfläche des Haltebügels 23 um so viel größer, daß zwischen diesen beiden Teilen eine gegenseitige Schwenkbewegung um die Achse des Koppelgliedes 22 um bis zu 1° möglich ist.Part group 21.1 includes a vertically upwardly directed recess 24 on the underside 25 and a groove 26 adjoining it. The recess 24, like the coupling element 22, has a rectangular plan area, which is only so much larger than the plan area of the coupling member that between the two Sharing a mutual rotary movement around the vertical axis by up to 1 ° is possible. The groove 26 is matched to the shape of the bracket 23 so that the bracket 23 has full space in it. The plan area of the groove 26 is so much larger than the plan area of the bracket 23 that between these two parts a mutual pivoting movement about the axis of the coupling member 22 is possible by up to 1 °.

Der Grundkörper 17 weist auf seiner Unterseite 25 eine Anzahl kreisrunder Ausnehmungen 27 auf, in die Fußnoppen 28 eingesetzt sind. Die Fußnoppen 28 ragen etwa 3 bis 5 mm über die Unterseite 25 des Grundkörpers 17 nach unten heraus, so daß die Fußschwelle 11 bei ihrem Einsatz, zumindest auf befestigten Straßen und Plätzen, im allgemeinen nur auf den Fußnoppen 28 aufliegt.The base body 17 has on its underside 25 a number of circular recesses 27 into which foot knobs 28 are inserted. The foot knobs 28 protrude approximately 3 to 5 mm downwards over the underside 25 of the base body 17, so that the foot sill 11 generally only rests on the foot knobs 28 when they are used, at least on paved roads and squares.

Die Fußnoppen 28 dienen hauptsächlich der Erhöhung der Rutschsicherheit der Fußschwelle 11 oder, mit anderen Worten, der Erhöhung des Verschiebewiderstandes der Fußschwelle 11 beim Auftreten seitlicher Verschiebekräfte. Die Fußnoppen 28 sind daher aus einem Werkstoff geringerer Härte als der Werkstoff des Grundkörpers 17 hergestellt. Zweckmäßigerweise sind sie aus einem homogenen Kautschuk oder einem Kunststoff hergestellt, der einerseits eine große Reißfestigkeit und andererseits eine nur geringe Formfestigkeit hat, der also elastisch sehr nachgiebig und zugleich sehr zäh ist. Infolge der geringen Formfestigkeit vermag der Werkstoff der Fußnoppen 28 sich in die Unebenheiten der Straßenoberfläche hineinzudrücken, so daß hier ein zusätzlicher Formschluß erreicht wird.The foot knobs 28 serve primarily to increase the slip resistance of the foot sill 11 or, in other words, to increase the resistance to displacement of the foot sill 11 when lateral displacement forces occur. The foot knobs 28 are therefore made of a material of lower hardness than the material of the base body 17. They are expediently made from a homogeneous rubber or a plastic which on the one hand has great tear strength and on the other hand has only a low level of dimensional stability, which is therefore very flexible and at the same time very tough. As a result of the low dimensional stability, the material of the foot knobs 28 is able to press into the unevenness of the road surface, so that an additional positive connection is achieved here.

Wie aus Fig. 5 ersichtlich ist, hat der Grundkörper 17 eine Querschnittsform, bei der die Seitenwände 29 und die Oberseite 14 entlang einer Hüllkurve 30 ineinander übergehen, die einen zumindest annähernd stetigen Verlauf hat. Diese Hüllkurve 30 ist im Bereich der Oberseite 14 und im Bereich der Seitenwände durchgehend konvex gekrümmt, wobei im Bereich des unteren Abschnittes 29.1 der Seitenwände, der an die Unterseite 25 des Grundkörpers 17 angrenzt, die Krümmung abnimmt. Die Hüllkurve 30 kann in diesem unteren Abschnitt 29.1 bis zur Tangente an den vorhergehenden Kurvenabschnitt 29.2 auch geradegestreckt sein.As can be seen from FIG. 5, the base body 17 has a cross-sectional shape in which the side walls 29 and the upper side 14 merge into one another along an envelope curve 30, which has an at least approximately continuous course. This envelope curve 30 is continuously convexly curved in the area of the upper side 14 and in the area of the side walls, the curvature decreasing in the area of the lower section 29.1 of the side walls, which adjoins the underside 25 of the base body 17. The envelope curve 30 can also be straight in this lower section 29.1 up to the tangent to the preceding curve section 29.2.

Im Bereich jeder Seitenwand 29 ist eine gegenüber der Hüllkurve 30 abgesetzte Stufe 31 vorhanden. Diese Stufe 31 ist gegenüber der Hüllkurve 30 nach innen abgesetzt oder zurückgesetzt. An der Übergangsstelle zwischen dem unteren Abschnitt 29.1 der Seitenwand 29 und der Stufe 31 ist eine Kante 32 vorhanden. Der daran anschließende erste Abschnitt 33.1 der Umrißlinie 33 der Stufe 31 ist zumindest annähernd waagerecht ausgerichtet. Der weitere Abschnitt 33.2 der Umrißlinie 33 der Stufe 31 verläuft zunächst konkav gekrümmt und geht anschließend mit konvexer Krümmung in den oberen Abschnitt 29.2 der Umrißlinie der Seitenwand 29, d.h. in die Hüllkurve 30, über.In the area of each side wall 29 there is a step 31 which is offset from the envelope curve 30. This step 31 is offset or set back in relation to the envelope curve 30. An edge 32 is present at the transition point between the lower section 29.1 of the side wall 29 and the step 31. The adjoining first section 33.1 of the contour line 33 of the step 31 is oriented at least approximately horizontally. The further section 33.2 of the outline 33 of the step 31 initially has a concave curvature and then goes with a convex curvature into the upper section 29.2 of the outline of the side wall 29, i.e. into the envelope 30, over.

Die Stufe 31 der Umrißlinie des Grundkörpers 17 dient als Kletterstufe für Fahrzeugräder, die in einem spitzen Winkel an die Fußschwelle 11 anstreifen oder auch in einem weniger spitzen Winkel auf sie zurollen. Durch diese Kletterstufe soll das Hinaufklettern oder Hinaufrollen der Fahrzeugräder auf die Fußschwelle 11 hinauf erleichtert werden. Dabei wird zugleich durch die dann sofort einsetzende Belastung der Fußschwelle 11 das Wegschieben der Fußschwelle 11 verhindert.The step 31 of the outline of the base body 17 serves as a climbing step for vehicle wheels which touch the foot sill 11 at an acute angle or roll towards it at a less acute angle. This climbing step is intended to make it easier to climb up or roll the vehicle wheels up onto the threshold 11. At the same time, the pushing away of the sleeper 11 is prevented by the immediate onset of loading of the sleeper 11.

Bei dem aus Fig. 6 ersichtlichen Grundkörper 17.2 sind im Bereich der beiden Seitenwände 34 zwei Stufen 35.1 und 35.2 vorhanden, die zumindest annähernd in gleicher Weise wie die Stufe 31 ausgebildet sind und gegenüber der gemeinsamen Hüllkurve 30 des Grundkörpers 17.2 nach innen abgesetzt sind. In ähnlicher Weise weist der aus Fig. 7 ersichtliche Grundkörper 17.3 im Bereich seiner Seitenwände 36 drei Stufen 37.1, 37.2 und 37.3 auf, die gegenüber der Hüllkurve 30 abgesetzt sind.In the case of the main body 17.2 shown in FIG. 6, two steps 35.1 and 35.2 are present in the region of the two side walls 34, which are at least approximately designed in the same way as the step 31 and are offset inwards relative to the common envelope curve 30 of the main body 17.2. Similarly, the base body 17.3 shown in FIG. 7 has three steps 37.1, 37.2 and 37.3 in the region of its side walls 36, which are offset from the envelope curve 30.

Die Hüllkurve 30 kann im Bereich der Oberseite 14 bis hin zum oberen Abschnit 29.2 der Seitenwände 29 eine zumindest annähernd gleichbleibende Krümmung haben. Damit die Fußschwelle 11 eine etwas flachere und breitere Oberseite 14 erhält, kann der am Übergang von der Oberseite 14 zu den Seitenwänden 29 hin gelegene Abschnitt 38 der Hüllkurve 30 auch stärker gekrümmt sein und dafür der Kurvenabschnitt der Oberseite 14 eine geringere Krümmung haben. Im Extremfall kann die Oberseite sogar bis zur Tangente an die beiden Übergangsabschnitte 38 geradegestreckt sein.The envelope curve 30 can have an at least approximately constant curvature in the region of the upper side 14 up to the upper section 29.2 of the side walls 29. To ensure that the threshold 11 has a somewhat flatter and wider upper side 14, the section 38 of the envelope curve 30 located at the transition from the upper side 14 to the side walls 29 can also be more curved and the curved section of the upper side 14 can therefore have a smaller curvature. In extreme cases, the upper side can even be stretched straight up to the tangent to the two transition sections 38.
