Description

Die Erfindung bezieht sich auf ein Rollbrett gemäß Oberbegriff Patentanspruch 1.The invention relates to a roller board according to the preamble of claim 1.

Rollbretter dieser Art sind insbesondere auch unter dem Begriff "Skateboard" bekannt.Roller boards of this type are also known in particular under the term "skateboard".

Die Lagerung bzw. Halterung der Radachsen erfolgt bei diesen bekannten, als Skateboard ausgebildeten Rollbrettern unter Verwendung von Lagerklötzen, die gleichzeitig auch das Lenkgetriebe bilden und jeweils eine Gummipuffer-Anordnung in der Weise besitzen, daß beim Neigen bzw. Schrägstellen des Standbrettes um die Längsachse zum Steuern des Rollbrettes ein gegensinniges Verschwenken der Radachsen um eine vertikale Hochachse erfolgt.The storage or mounting of the wheel axles takes place in these known skateboarding roller boards using bearing blocks, which also form the steering gear and each have a rubber buffer arrangement in such a way that when tilting or tilting the standing board around the longitudinal axis Control of the roller board is an opposite pivoting of the wheel axles about a vertical axis.

Die bekannten Rollbretter sind für ein Fahren auf möglichst glattem Untergrund geeignet und bestimmt.The known roller boards are suitable and intended for driving on as smooth a surface as possible.

Aufgabe der Erfindung ist es, ein Rollbrett aufzuzeigen, welches für ein Abfahren im Gelände geeignet ist.The object of the invention is to show a roller board which is suitable for off-road skiing.

Zur Lösung dieser Aufgabe ist ein Rollbrett entsprechend dem kennzeichnenden Teil des Patentanspruches 1 ausgebildet.To solve this problem, a roller board is designed according to the characterizing part of patent claim 1.

Das erfindungsgemäße Rollbrett zeichnet sich durch eine kompakte und robuste Konstruktion aus. Da die Radachsen über der Oberseite oder auf der Oberseite des Standbrettes vorgesehen sind, befinden sich auch zumindest die wesentlichen Elemente der Halterung der jeweiligen Radachse sowie des jeweiligen Lenkgetriebes nicht unter dem Standbrett, sondern zumindest über der Unterseite dieses Standbrettes bevorzugt ebenfalls an oder auf der Oberseite des Standbrettes, so daß beim Fahren im Gelände durch Hindernisse, Steinschläge usw. weder die Radachse, noch deren Halterung und die zugehörigen Lenkgetriebe beschädigt werden können.The roller board according to the invention is characterized by a compact and robust construction. Since the wheel axles are provided over the top or on the top of the standing board, at least the essential elements of the mounting of the respective wheel axle and the respective steering gear are not located under the standing board, but at least above the underside of this standing board, preferably also on or on the top of the standing board, so that when driving off-road, obstacles, stone chips, etc., neither the wheel axle, nor its holder and the associated steering gear can be damaged.

Das erfindungsgemäße Rollbrett ist somit optimal für das Fahren im freien Gelände, beispielsweise für ein Abfahren über Hänge, Wege usw. geeignet.The roller board according to the invention is thus optimally suitable for driving in open terrain, for example for descending slopes, paths, etc.

In Weiterbildung der Erfindung erfolgt die Steuerung nicht durch Gummipuffer, sondern durch mechanische Lenkgetriebe, die ein sehr exaktes Steuern ermöglichen. Am Rollbrett bzw. an dessen Standbrett ist wenigstens eine Bindung, beispielsweise in Form wenigstens einer Fußschlaufe vorgesehen.In a development of the invention, the control is not carried out by rubber buffers, but by mechanical steering gears, which enable very precise control. At least one binding, for example in the form of at least one foot strap, is provided on the roller board or on its stand board.

Bevorzugt ist das Rollbrett mit einer Selbstbremsvorrichtung, wie sie beispielsweise von Skiern her bekannt ist, versehen oder am Rollbrett ist ein Fangriemen befestigt.The roller board is preferably provided with a self-braking device, as is known, for example, from skis, or a safety strap is attached to the roller board.

Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Developments of the invention are the subject of the dependent claims.

Die Erfindung wird im folgenden anhand der Figuren an einem Ausführungsbeispiel näher erläutert. Es zeigen:

The invention is explained in more detail below with reference to the figures using an exemplary embodiment. Show it:

Das in den Figuren dargestellte Rollbrett besteht im wesentlichen aus einem Tritt- oder Standbrett 1, welches bei der dargestellten Ausführungsform so ausgeführt ist, daß es einen mittleren, die eigentliche Standfläche des Rollbrettes bildenden bauchigen Abschnitt 1' sowie zwei von diesem wegstehende, schmälere zungenartige Abschnitte 1'' besitzt. Die Abschnitte 1'' liegen mit ihrer Längserstreckung in der Längsachse L des Rollbrettes und sind um 180o gegeneinander versetzt am mittleren Abschnitt 1' vorgesehen. Im Bereich der freien Enden sind die beiden Abschnitte 1'' skispitzenartig leicht aufgebogen, wie dies insbesondere in der Fig. 2 bei 2 dargestellt ist.The roller board shown in the figures consists essentially of a footboard or stand board 1, which in the embodiment shown is designed such that it has a central, bulbous section 1 'which forms the actual base surface of the roll board and two narrower tongue-like sections which project away from it 1 ''. The sections 1 ″ lie with their longitudinal extension in the longitudinal axis L of the roller board and are provided offset from one another by 180 ° on the central section 1 ′. In the area of the free ends, the two sections 1 ″ are ski tip-like slightly bent, as is shown in particular in FIG. 2 at 2.

An den Abschnitten 1'' und in einem vorgegebenen Abstand von den Schaufelenden 2, der (Abstand) bei der dargestellten Ausführungsform etwas kleiner ist als die Gesamtlänge des jeweiligen Abschnittes 1'', ist an jedem Abschnitt 1'' eine Radachse 3 befestigt, und zwar derart, daß die mit ihrer Längserstreckung quer zur Längsachse L verlaufende Radachse 3 deutlich über der Oberseite des Standbrettes bzw. des jeweiligen Abschnittes 1'' liegt. Jede Radachse 3 steht beidseitig über den jeweiligen Abschnitt 1'' mit einer Länge vor und an beiden Enden jeder Radachse 3 ist ein Rad 4 frei drehbar gelagert. Jedes Rad 4 ist bei der dargestellten Ausführungsform als Speichen-Rad mit einer Vollgummi-Bereifung ausgebildet. Durch eine entsprechende Halterung 5 mit Lenkgetriebe 6 sind die Radachsen 3 um eine vertikale Hochachse V, die senkrecht zur Längsachse L verläuft lenk- bzw. schwenkbar, und zwar jeweils gegensinnig durch entsprechendes Neigen bzw. Schwenken des Standbrettes 1 um die Längsachse L, so daß ein Lenken des Rollbrettes für Kurvenfahrten möglich ist. In der Geradeaus-Stellung liegen die Radachsen 3 parallel zueinander sowie auch parallel zu der Ebene des Standbrettes 1 und schneiden die Längsachse L in einem Winkel von 90o.At the sections 1 ″ and at a predetermined distance from the blade ends 2, which (distance) in the illustrated embodiment is somewhat smaller than the total length of the respective section 1 ″, a wheel axle 3 is attached to each section 1 ″, and in such a way that the longitudinal axis of the wheel axis 3, which extends transversely to the longitudinal axis L, is clearly above the top of the base board or of the respective section 1 ″. Each wheel axle 3 projects on both sides over the respective section 1 ″ with a length and at both ends of each wheel axle 3 a wheel 4 is freely rotatably mounted. In the illustrated embodiment, each wheel 4 is designed as a spoke wheel with solid rubber tires. By means of a corresponding holder 5 with steering gear 6, the wheel axles 3 can be steered or pivoted about a vertical vertical axis V, which runs perpendicular to the longitudinal axis L, in each case in opposite directions by correspondingly tilting or pivoting the standing board 1 about the longitudinal axis L, so that steering of the roller board for cornering is possible. In the straight ahead position, the wheel axles 3 are parallel to each other and also parallel to the plane of the standing board 1 and intersect the longitudinal axis L at an angle of 90 o.

Die einen relativ großen Durchmesser aufweisenden Räder 4 sind so angeordnet, daß sie seitlich über die Ebene der Längsseite des mittleren Abschnittes 1' vorstehen.The relatively large diameter wheels 4 are arranged so that they protrude laterally beyond the plane of the long side of the central section 1 '.

Alle funktionswesentlichen Elemente der Halterungen 5 und Lenkgetriebe 6 befinden sich ebenfalls auf der Oberseite des Standbrettes 1 bzw. des jeweiligen Abschnittes 1'' und sind damit gegen Beschädigung weitestgehend geschützt vorgesehen.All functionally essential elements of the brackets 5 and steering gear 6 are also located on the top of the base board 1 or the respective section 1 ″ and are therefore largely protected against damage.

Die Halterung 5 ist kardangelenkartig ausgebildet, d.h. sie besteht jeweils aus einem in dem betreffenden Abschnitt 1'' um die vertikale Achse V drehbar gelagerten Lagerkörper 7, der hierfür mit einem angeformten Zapfen 8 in ein Lagerelement 9 am Abschnitt 1'' eingreift. Am Lagerkörper 7 bzw. an einem an diesem Lagerkörper oberhalb des Zapfens 8 gebildeten gabelartigen Abschnitt 7' ist die jeweilige Radachse 3 in ihrer Mitte um eine horizontale Achse schwenkbar gelagert, die senkrecht zur Achse des Lagerzapfens 8 und in der Ausgangs- bzw. Null-Stellung der Lenkung achsgleich mit der Achse L liegt.The holder 5 is designed like a cardan joint, i.e. it consists in each case of a bearing body 7 rotatably mounted in the relevant section 1 ″ about the vertical axis V, which for this purpose engages with a molded pin 8 in a bearing element 9 on the section 1 ″. On the bearing body 7 or on a fork-like section 7 'formed on this bearing body above the pin 8, the respective wheel axis 3 is pivotally mounted in its center about a horizontal axis which is perpendicular to the axis of the bearing pin 8 and in the initial or zero Position of the steering is coaxial with the axis L.

Die Gelenkgetriebe 6 sind bei der in den Figuren 1 bis 3 dargestellten Ausführungsform jeweils von zwei kreisbogenförmigen Steuerkurven 10 gebildet, die an der Oberseite des Abschnittes 1'' befestigt sind, und zwar jeweils im Bereich einer Längsseite des betreffenden Abschnittes 1'' konzentrisch zur Achse des Zapfens 8. Die teilkreisförmigen Steuerkurven bilden mit ihrem oberen, den Abschnitt 1'' abgewandten Rand jeweils eine schiefe Ebene 11, gegen die jeweils eine auf der Radachse 3 vorgesehene Kurvenrolle 12 anliegt. Die Steuerkurven 10 sind jeweils so ausgeführt, daß die schiefe Ebene 11 jeder Steuerkurve 10 mit ihrem niedrigsten Punkt jeweils dem aufgebogenen Ende 2 des betreffenden Abschnittes 1'' näher liegt als mit ihrem höheren Ende. Weiterhin sind die Steuerkurven 10 so angeordnet, daß beim Verschwenken des Standbrettes 1 um die Längsachse L durch die hierbei an jedem Lenkgetriebe 6 von einer Steuerkurve 10 auf eine Rolle 12 ausgeübte Kraft die Radachsen 3 um die Achse des Zapfens 8 aus der Ausgangsstellung verschwenkt werden, und zwar beide Radachsen 3 gegenläufig. Dieser Schwenk- bzw. Lenkwinkel ist dabei von dem Neigungswinkel abhängig ist, um den das Standbrett 1 aus der Ausgangsstellung um die Längsachse L verschwenkt wurde.In the embodiment shown in FIGS. 1 to 3, the articulated gears 6 are each formed by two circular control cams 10 which are fastened to the upper side of the section 1 ″, in each case in the region of a longitudinal side of the section 1 ″ concerned, concentrically to the axis of the pin 8. The part-circular control cams each form an inclined plane 11 with their upper edge facing away from section 1 ″, against which a cam roller 12 provided on the wheel axle 3 abuts. The control cams 10 are each designed such that the inclined plane 11 of each control curve 10 with its lowest point is closer to the bent end 2 of the relevant section 1 ″ than with its higher end. Furthermore, the control cams 10 are arranged such that when the standing board 1 is pivoted about the longitudinal axis L by the force exerted on each steering gear 6 by a control cam 10 on a roller 12, the wheel axles 3 are pivoted about the axis of the pin 8 from the initial position, namely both wheel axles 3 in opposite directions. This pivoting or steering angle is dependent on the angle of inclination by which the standing board 1 has been pivoted from the initial position about the longitudinal axis L.

Um Toleranzen auszugleichen und eine verbesserte Lenkung beider Radachsen 3 zu erreichen, kann es zweckmäßig sein, die Radachsen durch einen zusätzlichen, starren Lenker 13 zu verbinden, der an einem Ende an der einen Radachse 3 und am anderen Ende an der anderen Radachse 3 vorzugsweise mittels eines Kugelgelenkes oder eines kugelgelenkartigen Gelenkes angelenkt ist, und zwar jeweils auf gegenüberliegenden Seiten der Längsachse L, d.h. bei der für die Fig. 1 gewählten Darstellung bei der dortigen unteren Radachse 3 an der linken und bei der oberen Radachse 3 am rechten, von der Halterung 5 wegstehenden Teil.In order to compensate for tolerances and to achieve an improved steering of both wheel axles 3, it may be expedient to connect the wheel axles by means of an additional, rigid link 13, preferably at one end to one wheel axle 3 and at the other end to the other wheel axle 3 a ball joint or a ball joint-like joint is articulated, in each case on opposite sides of the longitudinal axis L, that is to say in the illustration chosen for FIG. 1, with the lower wheel axle 3 there on the left and in the upper wheel axle 3 on the right, which projects away from the holder 5.

Durch nicht dargestellte Federmittel sind die Radachsen 3 in ihre nicht ausgelenkte, d.h. normale Stellung vorgespannt. Diese Federmittel sind beispielsweise Torsions-Federmittel, die im Bereich des Lagerelementes 9 vorgesehen sind.By spring means, not shown, the wheel axles 3 are in their undeflected, i.e. biased normal position. These spring means are, for example, torsion spring means which are provided in the area of the bearing element 9.

An der Oberseite des Standbrettes sind im Abschnitt 1' als Bindung Fußschlaufen 14 für den Benutzer vorgesehen. Bei der dargestellten Ausführungsform sind insgesamt vier Fußschlaufen 14 vorhanden, die um die Mitte des Abschnittes 1' in gleichmäßigen Winkelabständen versetzt derart angeordnet sind, daß jede Fußschlaufe 14 um 45o gegenüber der Längsachse L versetzt ist.On the top of the standing board, foot straps 14 are provided for the user in section 1 '. In the embodiment shown, there are a total of four foot straps 14 which are arranged offset at equal angular intervals around the center of section 1 'in such a way that each foot strap 14 is offset by 45 ° with respect to the longitudinal axis L.

Das beschriebene Rollbrett besitzt eine robuste Konstruktion, die ein Fahren im Gelände, insbesondere auch ein Abfahren auf abschüssigen Wegen, Wiesen usw. ermöglicht.The roller board described has a robust construction, which enables driving off-road, in particular also a descent on sloping paths, meadows, etc.

Fig. 4 zeigt eine abgewandelte Ausführungsform, bei der anstelle der Steuerkurven 10 Steuerkurven 15 vorgesehen sind, die rahmenartig ausgebildet sind und an einer innenliegenden Rahmenfläche jeweils eine der schiefen Ebene 11 entsprechende schiefe Ebene 16 bilden.FIG. 4 shows a modified embodiment in which 10 control cams 15 are provided instead of the control cams, which are frame-like and each form an inclined plane 16 corresponding to the inclined plane 11 on an inner frame surface.

Fig. 5 zeigt schließlich eine Ausführung, bei der die jeweiligen Lenkgetriebe in die Lagerung bzw. Halterung der jeweiligen Radachse 3 integriert sind. Hierfür ist jede Radachse 3 in ihrem mittleren Bereich an einem Lagerkörper 18 befestigt, der mit einem Lagerzapfen 19, dessen Achse senkrecht zur Längserstreckung der zugehörigen Radachse 3 sowie bei nicht ausgelenkten Radachsen 3 auch senkrecht zur Längserstreckung L und damit in der vertikalen Achse V liegt.5 finally shows an embodiment in which the respective steering gears are integrated in the mounting or mounting of the respective wheel axle 3. For this purpose, each wheel axle 3 is fastened in its central region to a bearing body 18 which, with a bearing journal 19, the axis of which is perpendicular to the longitudinal extent of the associated wheel axle 3 and, in the case of non-deflected wheel axles 3, also perpendicular to the longitudinal extent L and thus in the vertical axis V.

Der Zapfen 19 ist in einem Lagerkörper 20 drehbar gelagert, der seinerseits um die Längsachse L schwenkbar am Standbrett bzw. in einer Ausnehmung 21 des jeweiligen Abschnittes 1'' angeordnet ist. Hierfür ist das Lagerelement 20 an seiner der Radachse 3 abgewandten Unterseite napfartig ausgeführt, d.h. das Lagerelement 20 besitzt dort eine von einem Wandelement 22 umgebene Ausnehmung 23. Unter Verwendung zweier Lagerzapfen 24, die jeweils in das Wandelement 22 eingreifen, ist die schwenkbare Lagerung des Lagerelementes 20 um die Längsachse L realisiert. Auf einem der verdrehungssicher am Standbrett 1 befestigten Lagerzapfen 24 sitzt ein als Kegelrad ausgebildetes Zahnrad 25, welches mit einem auf dem Zapfen 19 verdrehungssicher befestigten und ebenfalls als Kegelrad ausgebildeten Zahnrad 26 in Eingriff steht. Durch die beiden Zahnräder 25 und 26, die in der Ausnehmung 23 geschützt untergebracht sind, ist beim Schwenken des Standbrettes 1 um die Längsachse L das Lenken der Radachsen 3 möglich.The pin 19 is rotatably mounted in a bearing body 20, which in turn is arranged on the stand board or in a recess 21 of the respective section 1 ″ pivotable about the longitudinal axis L. For this purpose, the bearing element 20 is cup-shaped on its underside facing away from the wheel axle 3, i.e. the bearing element 20 there has a recess 23 surrounded by a wall element 22. The use of two bearing pins 24, each of which engages in the wall element 22, realizes the pivotable mounting of the bearing element 20 about the longitudinal axis L. On one of the pivot pins 24, which is secured against rotation on the stand board 1, there is a gear 25 designed as a bevel gear, which meshes with a gear 26, which is secured against rotation on the pin 19 and is also designed as a bevel gear. Due to the two gear wheels 25 and 26, which are accommodated in the recess 23 in a protected manner, the steering of the wheel axles 3 is possible when the standing board 1 is pivoted about the longitudinal axis L.

Bei allen dargestellten Ausführungsformen für die Lagerung des Lagerkörpers 7 bzw. des zugehörigen Zapfens 8 und des Lagerkörpers 18 bzw. des zugehörigen Zapfens 19 jeweils ein beispielsweise als Rollen- oder Kugellager ausgebildetes Lager vorgesehen, welches sowohl als Radiallager als auch als Axiallager wirkt. Mit 27 ist noch ein Fangriemen bezeichnet, der an einem Ende mit dem Standbrett 1 verbunden ist.In all of the illustrated embodiments for the mounting of the bearing body 7 or of the associated pin 8 and of the bearing body 18 or of the associated pin 19, a bearing designed, for example, as a roller or ball bearing is provided, which acts both as a radial bearing and as an axial bearing. With 27 is also a lanyard, which is connected at one end to the stand board 1.

Die Erfindung wurde voranstehend an Ausführungsbeispielen beschrieben. Es versteht sich, daß zahlreiche Änderungen sowie Abwandlungen möglich sind, ohne daß dadurch der der Erfindung zugrundeliegende Erfindungsgedanke verlassen wird. So ist es beispielsweise auch möglich, anstelle des Fangriemens 27 eine Selbstbremsvorrichtung vorzusehen, wie sie von Skiern her bekannt ist. Weiterhin ist es auch möglich, die Räder 5 mit einer Luftdruckbereifung zu versehen und/oder eine gefederte Einzelradlagerung für jedes Rad vorzusehen.The invention has been described above using exemplary embodiments. It goes without saying that numerous changes and modifications are possible without thereby departing from the inventive idea on which the invention is based. For example, instead of the safety belt 27, it is also possible to provide a self-braking device, as is known from skis. Furthermore, it is also possible to provide the wheels 5 with air pressure tires and / or to provide sprung individual wheel bearings for each wheel.
