Description

Die vorliegende Erfindung betrifft ein Rad, insbesondere für ein Sportgerät, gemäß dem Oberbegriff des Anspruchs 1. Insbesondere betrifft die Erfindung ein Rad mit einer Felge, mit einem auf der Felge gehaltenen Reifen und mit federnd ausgebildeten Stützelementen für den Reifen, auf denen der Reifen aufliegt und von denen der Reifen zumindest abschnittsweise in seinem Querschnittsverlauf unterstützt wird.The present invention relates to a wheel, in particular for a sports device, according to the preamble of claim 1. In particular, the invention relates to a wheel with a rim, with a tire held on the rim and with resilient support elements for the tire on which rests the tire and of which the tire is at least partially supported in its cross-sectional profile.

Es besteht zunehmender Bedarf an neuartigen Sportgeräten, die eine Erweiterung des Spektrums von Freizeitaktivitäten ermöglichen. Eine Form von Sportgeräten sind solche, die eine dem Schifahren ähnliche Abfahrt auf schneefreien Hängen ermöglichen, also zum sogenannten Grasschilauf dienen. Solche Sportgeräte sind im Allgemeinen ähnlich wie Schier aufgebaut, d.h. sie sind länglich mit einer Bindung zur Befestigung an einem Schuh, besitzen jedoch mindestens zwei Rollen anstelle der Laufflächen von Schiern.There is an increasing demand for new types of sports equipment that allow for an expansion of the range of leisure activities. A form of sports equipment are those that allow a ski-related descent on snow-free slopes, so serve for so-called grass skiing. Such sports equipment is generally constructed similar to skis, i. they are elongated with a binding for attachment to a shoe, but have at least two rollers instead of the running surfaces of skis.

Der eigentliche Grasschilauf wird auf Wiesen durchgeführt und setzt somit einen ausreichend glatten Untergrund voraus, der weitgehend frei von Hindernissen ist. Im Sinne der vorliegenden Erfindung soll jedoch der Begriff Grasschilauf auch auf Aktivitäten in rauerem Gelände ausgedehnt werden, d.h. beispielsweise auf Abfahrten auf geschotterten Forststraßen und anderem Untergrund. Das Sportgerät und insbesondere das Rad eines solchen Sportgeräts im Sinne der Erfindung soll daher ein weitgehend geländetaugliches Verhalten aufweisen, so dass man nicht an die Verwendung auf Wiesen gebunden ist.The actual grass skiing is done on meadows and thus requires a sufficiently smooth surface, which is largely free of obstacles. For the purposes of the present invention, however, the term grasshopper is also to be extended to activities in rougher terrain, i. for example, on descents on gravel forest roads and other subsoil. The sports equipment and in particular the wheel of such a sports equipment in the context of the invention should therefore have a largely off-road behavior, so that one is not bound to the use of meadows.

Aber auch für das Befahren weitgehend glatter Oberflächen, wie etwa befestigte Straßen oder Wege sind herkömmliche Räder nicht vollständig befriedigend. Es hat sich herausgestellt, dass bei herkömmlichen Rädern von Inline-Skatern hochfrequente Schwingungen auftreten, die auf die Beine des Anwenders übertragen werden und bei längerer Verwendung zu Gelenkproblemen führen können.But even for driving largely smooth surfaces, such as paved roads or paths conventional wheels are not completely satisfactory. It has been found that conventional wheels of in-line skaters experience high-frequency vibrations that are transmitted to the user's legs and can lead to joint problems with prolonged use.

Eine weitere Anforderung, die an ein Sportgerät gestellt wird, besteht darin, dass die Beherrschung möglichst leicht erlernbar ist und dass das Fahrverhalten angenehm sowie der Bewegungsablauf möglichst physiologisch ist, um Schädigungen des Bewegungsapparates zu vermeiden. Ein im Allgemeinen als sehr angenehm empfundener Bewegungsablauf, der die obigen Forderungen erfüllt, ist der sich beim Tiefschneefahren mit Schiern einstellende. Es ist daher wünschenswert, ein Sportgerät zu schaffen, das in seinem Fahrverhalten so weit wie möglich an einen Schi herankommt, der im Tiefschnee gefahren wird. Es soll insbesondere das Verhalten beim Drehen und beim Lastwechsel die Tiefschneefahrt simulieren.Another requirement that is made of a sports equipment, is that the mastery is as easy to learn and that the driving behavior pleasant and the movement is physiological as possible to avoid damage to the musculoskeletal system. A generally perceived as very pleasant movement that meets the above requirements, which is the case of deep snow skiing with skis. It is therefore desirable to have one To create sports equipment that comes as close as possible to a ski in its driving behavior, which is driven in deep snow. In particular, the behavior during turning and during load changes is intended to simulate deep snow driving.

Eine wesentliche Voraussetzung für das Erreichen des oben beschriebenen Fahrverhaltens ist eine entsprechende Ausbildung der Räder des Sportgeräts. Diese müssen einerseits eine bestimmte Geländegängigkeit ermöglichen und andererseits durch ihre Elastizität ein entsprechendes Lenkverhalten gewährleisten, um Richtungswechsel wie beim Schifahren zu ermöglichen.An essential prerequisite for achieving the driving behavior described above is a corresponding design of the wheels of the sports equipment. These must on the one hand allow a certain off-road capability and on the other hand ensure by their elasticity a corresponding steering behavior to allow changes of direction as in skiing.

Aus der WO 00/27490 ist ein Rad bekannt, das für Inline-Skater verwendbar ist. Dieses Rad besitzt eine Außenfelge, die gegenüber einer Innenfelge federnd gelagert ist, um Stöße abzufedern. Weiters ist aus der WO 98/41295 ein Rad bekannt, das ebenfalls für Inline-Skater vorgesehen ist. Um ein vorbestimmtes Bremsverhalten beim Querstellen des Skaters zu erreichen, ist ein torusförmiger Reifen vorgesehen, der sich um seine eigene Achse drehen kann und so eine entsprechend gebremste Seitwärtsbewegung des Rades ermöglicht. Beide oben beschriebenen vorbekannten Räder sind nicht in der Lage, das Fahrverhalten eines Schis beim Tiefschneefahren zu simulieren. Insbesondere kann mit den bekannten Rädern ein Betrieb in rauerem Gelände nicht durchgeführt werden.From the WO 00/27490 is a wheel known that is suitable for inline skaters. This wheel has an outer rim, which is resiliently mounted relative to an inner rim to cushion shocks. Furthermore, is from the WO 98/41295 a wheel known, which is also intended for inline skaters. In order to achieve a predetermined braking behavior when crossing the skater, a toroidal tire is provided, which can rotate about its own axis and thus enables a correspondingly braked sideways movement of the wheel. Both previously known wheels described above are unable to simulate the behavior of a ski during deep snow skiing. In particular, with the known wheels, operation in rougher terrain can not be performed.

Auch mit Rädern, die herkömmlicher Weise mit Luftreifen ausgestattet sind, wie sie etwa in der US 5,535,800 A offenbart sind, kann das Fahrverhalten nicht entsprechend dem gewünschten Tiefschneefahrverhalten angepasst werden.Also with wheels, which are conventionally equipped with pneumatic tires, such as those in the US 5,535,800 A disclosed, the driving behavior can not be adjusted according to the desired Tiefschneefahrverhalten.

Aus der WO 2004/060506 ist weiterhin ein Rad bekannt, das die obigen Anforderungen weitestgehend erfüllt. Die Herstellung eines solchen Rades ist jedoch relativ aufwändig und es besteht das Bedürfnis, das Gewicht des Rades zu verringern, ohne die Fahreigenschaften zu verschlechtern.From the WO 2004/060506 Furthermore, a wheel is known that meets the above requirements as far as possible. However, the production of such a wheel is relatively complicated and there is a need to reduce the weight of the wheel without degrading the driving characteristics.

Die US 5,743,316 A zeigt ein Rad für ein Fahrzeug, das als drucklos ausgebildetes Notrad einsetzbar ist. Dabei wird ein Vollgummireifen durch Federelemente gestützt, die an der Felge angebracht sind. Nachteilig ist bei diesem Rad, dass die Federelemente einerseits ausreichend steif sein müssen, um die erforderlichen Maximalkräfte aufnehmen zu können, aber andererseits biegeweich sein sollen, um den erwünschten Abrollkomfort zu gewährleisten. Diese Forderungen stehen in einem Widerspruch zueinander und können nur durch unbefriedigende Kompromisse teilweise erfüllt werden. Eine weitere Lösung, die einen verstärkten Reifen mit ähnlichen Nachteilen zeigt, ist in der BE 333 518 A offenbart.The US 5,743,316 A shows a wheel for a vehicle that can be used as a non-pressure trained emergency. In this case, a solid rubber tire is supported by spring elements which are attached to the rim. A disadvantage of this wheel, that the spring elements must be sufficiently stiff on the one hand in order to absorb the required maximum forces, but on the other hand be flexible to ensure the desired Abrollkomfort. These demands are in conflict with each other and can only partially be met by unsatisfactory compromises. Another solution that shows a reinforced tire with similar disadvantages is in BE 333 518 A disclosed.

Aufgabe der vorliegenden Erfindung ist es, ein Rad der oben beschriebenen Art so weiterzubilden, dass eine leichte und kostengünstige Herstellung möglich ist und eine Gewichtsverringerung erzielt werden kann. Eine weitere wesentliche Aufgabe ist es, das Auftreten und die Übertragung von Schwingungen weitestgehend zu verhindern und dadurch eine Schonung der Gelenke der Anwender zu erreichen.Object of the present invention is to develop a wheel of the type described above so that a simple and inexpensive production is possible and a reduction in weight can be achieved. Another essential task is to prevent the occurrence and transmission of vibrations as far as possible and thereby achieve a protection of the joints of the user.

Die vorstehenden Aufgaben werden durch die Merkmale des Anspruchs 1 gelöst. In den sich daran anschließenden Ansprüchen 2 bis 10 finden sich vorteilhafte Ausgestaltungen.The above objects are achieved by the features of claim 1. In the subsequent claims 2 to 10 are advantageous embodiments.

Insbesondere werden diese Aufgaben erfindungsgemäß dadurch gelöst, dass sich eine erste Gruppe von Stützelementen von einem ersten Lagerabschnitt der Felge vorzugsweise über die Mittelebene des Rades hinaus zur gegenüberliegenden Seite erstreckt und dass sich eine zweite Gruppe von Stützelementen von einem zweiten Lagerabschnitt der Felge, der dem ersten Lagerabschnitt gegenüberliegt, zur gegenüberliegenden Seite erstreckt.In particular, these objects are achieved according to the invention in that a first group of supporting elements extends from a first bearing section of the rim, preferably beyond the median plane of the wheel, to the opposite side, and a second group of supporting elements extends from a second bearing section of the rim, which is the first Bearing portion opposite, extending to the opposite side.

Ein definierter Auslenkweg eines Stützelementes wird erfindungsgemäß dadurch erhalten, dass der Auslenkweg eines Stützelementes durch einen Anschlag, insbesondere einen an der Felge vorgesehenen, vorzugsweise einstückig angeformten Vorsprung begrenzt ist.A defined Auslenkweg a support element according to the invention obtained by the Auslenkweg a support element by a stop, in particular a provided on the rim, preferably integrally molded projection is limited.

Das erfindungsgemäße Rad besitzt einen sehr einfachen Aufbau und ist dementsprechend leicht herstellbar. Gleichzeitig wird mit einem solchen Rad eine hervorragende Geländegängigkeit erreicht, die die Möglichkeit bietet, ein Fahrverhalten zu realisieren, das in Kombination mit entsprechenden Sportgeräten ein Erlebnis zufolge hat, welches dem Fahren im Tiefschnee weitgehend ähnlich ist. Bis zu einer bestimmten Querkraft, die auf das Rad quer zur Fahrtrichtung wirkt, wird ein stabiler Geradeauslauf erreicht. Bei größeren Querkräften erfolgt doch eine Verformung des Reifens im Bereich der Aufstandsfläche, so dass das Rad eine Bewegungskomponente quer zur eigentlichen Laufrichtung erhält. Da die Querkraftgrenze ab der die Querbewegung beginnt, von der Belastung des Rades abhängt und die Größe der Bewegungskomponente quer zur Laufrichtung mit zunehmender Neigung des Rades gegenüber eine senkrechten Ebene abnimmt, wird eine weitgehende Übereinstimmung mit dem Tiefschneefahren erreicht. Die Stützelemente verformen sich dabei unterschiedlich in Abhängigkeit von der Richtung der Querkraft. Durch die vorzugsweise zungenförmige Ausbildung der Stützelemente ist es möglich, die Biegesteifigkeit in Abhängigkeit vom Abstand vom Lagerabschnitt beliebig zu variieren, indem die Breite oder die Dicke der Stützelemente entsprechend variiert wird. Auf diese Weise kann das Verformungsverhalten und damit letztlich das Fahrverhalten des Rades wunschgemäß beeinflusst werden.The wheel of the invention has a very simple structure and is therefore easy to produce. At the same time with such a wheel excellent off-road capability is achieved, which offers the possibility to realize a driving behavior, which in combination with corresponding sports equipment has an experience that is largely similar to driving in deep snow. Up to a certain transverse force, which acts on the wheel transversely to the direction of travel, a stable directional stability is achieved. With larger transverse forces but still takes a deformation of the tire in the footprint, so that the wheel receives a component of movement transverse to the actual direction. Since the transverse force limit from which the transverse movement begins, depends on the load on the wheel and the size of the movement component decreases transversely to the direction with increasing inclination of the wheel relative to a vertical plane, a substantial match with the deep snow skiing is achieved. The support elements deform differently depending on the direction of the lateral force. Due to the preferably tongue-shaped design of the support elements, it is possible to vary the bending stiffness as a function of the distance from the bearing section as desired by the width or the thickness of the Support elements is varied accordingly. In this way, the deformation behavior and thus ultimately the handling of the wheel can be influenced as desired.

Die vorstehend erwähnten Vorteile können noch weiter dadurch unterstützt werden, dass die Stützelemente in Umfangsrichtung gegen den Reifen vorgespannt sind. Ergänzend hierzu oder unabhängig hiervon kann vorgesehen sein, dass die Stützelemente bogenförmig ausgebildet sind.The above-mentioned advantages can be further enhanced by biasing the support members circumferentially against the tire. In addition thereto or independently thereof, it may be provided that the support elements are arc-shaped.

Ein besonders angenehmes Fahrverhalten des erfindungsgemäßen Rades ergibt sich dadurch, dass die Stützelemente den Reifen zumindest annährend in seinem gesamten Querschnittsverlauf unterstützen.A particularly pleasant driving behavior of the wheel according to the invention results from the fact that the support elements support the tire at least approximately in its entire cross-sectional profile.

Produktionstechnisch besonders vorteilhaft ist es, wenn die Stützelemente an der Felge angeformt sind. Auf diese Weise sind Befestigungselemente oder sonstige Vorkehrungen zur Befestigung der Stützelemente nicht erforderlich.Production technology is particularly advantageous if the support elements are integrally formed on the rim. In this way, fasteners or other precautions for attachment of the support elements are not required.

Eine besonders einfache Herstellung sowie eine ebenso einfache Montage lässt sich dadurch erzielen, dass die Stützelemente kragarmartig an der Felge angeordnet sind. Hierbei können die Stützelemente zu ihrem freien Ende hin keilförmig ausgebildet sein.A particularly simple production and an equally simple assembly can be achieved in that the support elements are arranged cantilever-like on the rim. In this case, the support elements may be wedge-shaped towards their free end.

Bei einer kragarmartigen Ausgestaltung der Stützelemente beziehungsweise bei einer kragarmartigen Anbindung der Stützelemente an der Felge besteht weiterhin die Möglichkeit, dass die Stützelemente an dem ersten und dem zweiten Lagerabschnitt so angeordnet sind, dass die freien Enden der Stützelemente dieser beiden Lagerabschnitte diametral zueinander gegenüberliegend ausgerichtet sind. Dabei können sich die freien Enden der Stützelemente berühren. Ebenso besteht die Möglichkeit, dass die freien Enden der Stützelemente ein Abstand zueinander aufweisen. Alternativ hierzu kann ebenso vorgesehen sein, dass die Stützelemente des ersten Lagerabschnitts in Umfangsrichtung versetzt zu den Stützelementen des zweiten Lagerabschnitts angeordnet sind, so dass die freien enden der Stützelemente des ersten Lagerabschnittes in den Abstandsraum zwischen zwei aufeinander folgenden Stützelementen des zweiten Lagerabschnittes weisen. Auch hier besteht grundsätzlich die Möglichkeit, dass die Stützelemente des ersten Lagerabschnittes mit ihren freien Enden die freien Enden zweier aufeinander folgende Stützelemente des zweiten Lagerabschnitts berühren. Ebenfalls können auch hier die Stützelemente zueinander sowohl in axialer Richtung als auch in Umfangsrichtung einen Abstand zueinander aufweisen.In a cantilever-like configuration of the support elements or in a cantilever-like connection of the support elements to the rim, there is still the possibility that the support elements are arranged on the first and the second bearing portion so that the free ends of the support elements of these two bearing portions are aligned diametrically opposite each other. In this case, the free ends of the support elements can touch. It is also possible that the free ends of the support elements have a distance from each other. Alternatively, it may also be provided that the support elements of the first bearing section are arranged offset in the circumferential direction to the support elements of the second bearing section, so that the free ends of the support elements of the first bearing section in the distance space between two consecutive support elements of the second bearing section have. Here, too, there is basically the possibility that the support elements of the first bearing section with their free ends touch the free ends of two consecutive support elements of the second bearing section. Likewise, also here the support elements can have a distance from each other both in the axial direction and in the circumferential direction.

Grundsätzlich besteht die Möglichkeit, dass die Stützelemente nach Herstellung der Felge an dieser durch einen geeigneten Fertigungsschritt, wie beispielsweise Kleben, Ultraschweißen und der gleichen, angebracht werden. Eine besonders einfache Herstellung lässt sich, insbesondere bei einer kragarmartigen Ausgestaltung der Stützelemente an dem ersten und den zweiten Lagerabschnitt der Felge dadurch erzielen, dass die Stützelemente einstückig mit der Felge verbunden sind.In principle, there is the possibility that the support elements after manufacture of the rim are attached thereto by a suitable manufacturing step, such as gluing, ultrasonic welding and the like. A particularly simple production can be achieved, in particular with a cantilever-like configuration of the support elements on the first and the second bearing portion of the rim, by virtue of the fact that the support elements are integrally connected to the rim.

Um ein ausreichendes Einfedern der Stützelemente zu ermöglichen, ist es weiterhin vorteilhaft, wenn an der Felge ein Einfederhohlraum unterhalb der Stützelemente vorgesehen ist.In order to enable a sufficient compression of the support elements, it is also advantageous if a compression cavity is provided below the support elements on the rim.

Eine weitere Erhöhung der Stabilität kann dadurch erreicht werden, dass die Stützelemente im Bereich der Lagerabschnitte Ausnehmungen zur Aufnahme und Führung des Reifens aufweisen.A further increase in stability can be achieved in that the support elements in the region of the bearing sections have recesses for receiving and guiding the tire.

Besonders günstig hat es sich für das Fahrverhalten auch herausgestellt, wenn zwischen den einzelnen Stützelementen ein schmaler Spalt vorgesehen ist, insbesondere wenn der Spalt zwischen den Stützelementen eine gleichmäßige Breite aufweist.It has also proven to be particularly favorable for the driving behavior if a narrow gap is provided between the individual support elements, in particular if the gap between the support elements has a uniform width.

Weiterhin ist es vorteilhaft, wenn sich beide Gruppen von Stützelementen über die Mittelebende des Rades hinaus jeweils zur gegenüberliegenden Seite erstrecken.Furthermore, it is advantageous if both groups of support elements each extend beyond the middle end of the wheel to the opposite side.

Besonders günstig ist es, wenn in Umfangrichtung des Rades jeweils zwischen zwei Stützelementen der ersten Gruppe ein Stützelement der zweiten Gruppe angeordnet ist, sowie umgekehrt, wenn in Umfangrichtung des Rades jeweils zwischen zwei Stützelementen der zweiten Gruppe ein Stützelement der ersten Gruppe angeordnet ist. Auf diese Weise greifen die einzelnen Stützelemente der ersten Gruppe, beziehungsweise der zweiten Gruppe vergleichbar mit Zahnrädern oder kammartig ineinander ein, ohne einander jedoch zu berühren. Auf diese Weise wird über den Umfang des Rades ein gleichmäßiges Verformungsverhalten erreicht.It is particularly advantageous if in the circumferential direction of the wheel between each two support elements of the first group, a support member of the second group is arranged, and vice versa, when in the circumferential direction of the wheel between each two support elements of the second group, a support member of the first group is arranged. In this way, the individual support elements of the first group, or of the second group, engage with each other in a tooth-like or comb-like manner, but without touching each other. In this way, a uniform deformation behavior is achieved over the circumference of the wheel.

Es ist vorgesehen, dass jeweils ein Stützelement der ersten Gruppe auf einem Stützelement der zweiten Gruppe aufliegt. Dadurch wird ein besonders begünstigtes Federverhalten erreicht. Die seitliche Symmetrie wird insbesondere dadurch gewährleistet, dass in Umfangsrichtung abwechselnd ein Stützelemente der ersten Gruppe auf einem Stützelement der zweiten Gruppe bzw. ein Stützelemente der zweiten Gruppe auf einem Stützelement der ersten Gruppe aufliegt. Eine Begrenzung des Einfederns wird dadurch erreicht, dass die Stützelemente Anschlagvorsprünge aufweisen.It is envisaged that in each case a support element of the first group rests on a support element of the second group. As a result, a particularly favorable spring behavior is achieved. The lateral symmetry is ensured in particular by the fact that in the circumferential direction alternately a support elements of the first group on a support element of the second group or a support elements of the second group on a support element of the first Group rests. A limitation of the deflection is achieved in that the support elements have stop projections.

Die Federrate eines einzelnen Stützelementes kann auf verschiedenen Wegen beeinflusst werden. So besteht zum einen die Möglichkeit, dass die Federrate eines Stützelements durch die Materialauswahl einstellbar ist. Ergänzend oder alternativ hierzu kann weiterhin vorgesehen sein, dass die Federrate eines Stützelements durch die Geometrie des Stützelements einstellbar ist.The spring rate of a single support element can be influenced in various ways. Thus, on the one hand there is the possibility that the spring rate of a support element is adjustable by the choice of material. Additionally or alternatively, it may further be provided that the spring rate of a support element is adjustable by the geometry of the support element.

Besonders günstig es in diesem Zusammenhang, wenn die Felge zweiteilig ausgeführt ist und aus zwei Hälften besteht, die vorzugsweise im Bereich der Mittelebene des Rades verbunden sind. Dabei trägt jede Felgenhälfte die Stützelemente einer Gruppe, so dass aus den beiden Felgenhälften und dem Reifen bereits alle wesentlichen Elemente des Rades zusammengesetzt werden können. Alternativ dazu ist es möglich, dass die Felge zweiteilig ausgeführt ist und aus zwei Hälften besteht, von denen eine Hälfte einen Nabenabschnitt zur Aufnahme von Wälzlagern oder Gleitlagern aufweist. Auf diese Weise kann eine besonders robuste Lagerung des Rades erreicht werden, da sämtliche Lager in einem einzigen Bauteil angeordnet sind.Particularly favorable in this context, when the rim is made in two parts and consists of two halves, which are preferably connected in the region of the median plane of the wheel. Each rim half carries the support elements of a group, so that from the two rim halves and the tire already all the essential elements of the wheel can be assembled. Alternatively, it is possible that the rim is made in two parts and consists of two halves, one half of which has a hub portion for receiving rolling bearings or plain bearings. In this way, a particularly robust bearing of the wheel can be achieved, since all bearings are arranged in a single component.

Für das Material der Felge kann jeder geeignete Werkstoff ausgewählt werden. Besonders einfach lässt sich die Felge dadurch herstellen, dass sie aus Kunststoff gefertigt wird. Hierbei kann die Felge aus Zweikomponenten-Spritzguss hergestellt sein, wobei der Felgenkörper aus einem harten Kunststoff und die daran angeformten Stützelemente aus einem elastischen Kunststoff bestehen.For the material of the rim any suitable material can be selected. The rim can be produced particularly simply by being made of plastic. Here, the rim can be made of two-component injection molding, wherein the rim body made of a hard plastic and the support elements molded thereon are made of an elastic plastic.

Ein optimales Fahrverhalten des Rades, insbesondere für den Grasschilauf, kann dadurch erreicht werden, dass der Reifen drucklos aufgebaut ist. Ergänzend hierzu kann vorgesehen sein, dass das Rad als Vollgummireifen ausgebildet ist.An optimal handling of the wheel, especially for the grass can be achieved by the fact that the tire is constructed without pressure. In addition, it can be provided that the wheel is designed as a solid rubber tire.

Besondere Vorteile ergeben sich erfindungsgemäß dadurch, dass der Reifen dreischichtig aufgebaut ist und aus einer Lauffläche, einer weich-elastischen Innenschicht und einer Auflageschicht besteht. Die Auflageschicht ist dabei mechanisch widerstandsfähig, um der Reibung an den Stützelementen zu widerstehen. Die Lauffläche weist die für das jeweilige Gelände optimale Profilierung und eine geeignete Verschleißfestigkeit auf. Die weich-elastische Innenschicht ist in Dickenrichtung elastisch und ermöglicht ein feines Federverhalten.Particular advantages result according to the invention in that the tire is constructed in three layers and consists of a tread, a soft-elastic inner layer and a support layer. The support layer is mechanically resistant to withstand the friction on the support elements. The tread has the optimum profile for the respective terrain and suitable wear resistance. The soft-elastic inner layer is elastic in the thickness direction and allows a fine spring behavior.

Eine weitere besonders begünstigte Ausführungsvariante der Erfindung sieht an der Felge neben dem Reifen ein Eingriffselement vor, das sich entlang des Umfangs der Felge erstreckt. Dadurch kann der Eingriff der Kanten simuliert werden, der beim Fahren im Tiefschnee erst ab einem bestimmten Neigungswinkel in Querrichtung wirksam wird.Another particularly preferred embodiment of the invention provides an engagement element on the rim adjacent to the tire which extends along the circumference of the rim. This allows the engagement of the edges to be simulated, when driving in deep snow only from a certain angle of inclination in the transverse direction is effective.

Die Figuren 1 und 4 zeigen Räder die nicht Teil der Erfindung sind. Ausgestaltungen sowie einige Ausführungsbeispiele der vorliegenden Erfindung werden nachstehend in Verbindung mit den beigefügten Zeichnungen erläutert. Hierbei ist:

The FIGS. 1 and 4 show wheels that are not part of the invention. Embodiments and some embodiments of the present invention will be explained below in conjunction with the accompanying drawings. Here is:
Fig. 2
a first embodiment of the wheel according to the invention in a cross-sectional view;
Fig. 3
a detail of the wheel according to the invention in a plan view;
Fig. 5
a second embodiment in section.

Fig. 1 zeigt ein Rad das nicht Teil der Erfindung ist. Es besteht aus einer aus Kunststoff hergestellten Felge 1, die aus zwei Felgenhälften 2, 3 zusammengesetzt ist, welche entlang einer die Radachse in einem Winkel von 90° schneidenden Mittelebene 4 des Rades 1 aneinander befestigt sind. Die Befestigung kann dabei entweder unlösbar, beispielsweise durch Kleben oder lösbar zum Beispiel durch eine Schnapp- oder Schraubverbindung erfolgen. Eine Laufhülse 5 dient zur Aufnahme einer nicht dargestellten Lagerung und zur Zentrierung der Felgenhälften 2, 3. Der Reifen 6 kann, wie dargestellt, dreischichtig aufgebaut sein und besteht aus einer äußeren Lauffläche 9, einer weichelastischen Innenschicht 10 und einer Auflageschicht 11. Ebenso besteht die Möglichkeit, dass der Reifen 6 nur aus einer Schicht besteht. Fig. 1 shows a wheel that is not part of the invention. It consists of a rim 1 made of plastic, which is composed of two rim halves 2, 3, which are fastened together along a center plane 4 of the wheel 1 intersecting the wheel axis at an angle of 90 °. The attachment can be either insoluble, for example, by gluing or releasably done for example by a snap or screw. The tire 6 may, as shown, be constructed in three layers and consists of an outer running surface 9, a soft elastic inner layer 10 and a support layer 11. Likewise, the Possibility that the tire 6 consists of only one layer.

Die beiden Felgenhälften 2, 3 umschließen einen im Wesentlichen torusförmigen Innenraum 7, der jedoch nicht luftdicht abgeschlossen ist, so dass ein druckloser Reifen realisiert wird. Dieser torusförmige Innenraum 7 dient als Federhohlraum in der nachstehend noch näher beschriebenen Weise.The two rim halves 2, 3 enclose a substantially torus-shaped interior 7, which is not closed airtight, so that a non-pressure tire is realized. This toroidal interior 7 serves as a spring cavity in the manner described in more detail below.

An der ersten Felgenhälfte 2 befindet sich am äußeren Umfang eine erste Lagerstelle bzw. ein erster Lagerabschnitt 12, an der sich einerseits der Reifen 6 abstützt und andererseits einstückig an die erste Lagerstelle 12 angeformte Stützelemente 22 einer ersten Gruppe zu Abstützung des Reifens 6 bogenförmig vorragen. Analog dazu weist die zweite Felgenhälfte 3 eine Lagerstelle bzw. ein Lagerabschnitt 13 auf, von der ebenfalls einstückig an den zweiten Lagerabschnitt 13 angeformte Stützelemente 23 einer zweiten Gruppe entgegengesetzt zu den Stützelementen 22 der ersten Gruppe vorragen.On the first rim half 2 is located on the outer periphery of a first bearing or a first bearing portion 12, on the one hand, the tire 6 is supported and on the other hand integrally projecting integrally formed on the first bearing 12 integrally formed support members 22 of a first group to support the tire 6 arcuate. Analogously, the second rim half 3 has a bearing point or a bearing portion 13, from which also in one piece to the second bearing portion 13 molded support members 23 projecting from a second group opposite to the support members 22 of the first group.

Ein Erfindungsgemäßes Rad 1 ist in Fig. 2 gezeigt und unterscheidet sich von der von Fig. 1 dadurch, dass unterhalb der Lagerstellen 12, 13 Vorsprünge 14, 15 vorgesehen sind, die dazu dienen, das Einfedern der Stützelemente 22, 23 in den Federhohlraum 7 zu begrenzen und damit zu definieren. Mit unterbrochenen Linien ist ein Stützelement 22 der ersten Gruppe in eingefedertem Zustand dargestellt. Weiters unterscheidet sich die Ausführungsvariante der Fig. 2 von der von Fig. 1 dadurch, dass die Felge 1 einteilig ausgebildet ist.An inventive wheel 1 is in Fig. 2 shown and differs from that of Fig. 1 in that below the bearing points 12, 13 projections 14, 15 are provided, which serve to limit the compression of the support elements 22, 23 in the spring cavity 7 and thus to define. With broken lines, a support member 22 of the first group is shown in a compressed state. Furthermore, the variant of the differs Fig. 2 from the of Fig. 1 in that the rim 1 is formed in one piece.

Fig. 3 zeigt einen Abschnitt der Felge 1 in einer Draufsicht. Es ist ersichtlich, dass die Stützelemente 22, 23 zungenförmig oder kragarmartig ausgebildet sind und dass der Spalt 16 zwischen den Stützelementen 22, 23 schmal und gleichmäßig breit ist. Wie insbesondere aus Fig. 3 entnehmbar ist, weisen die Stützelemente 22 oder 23 der ersten und zweiten Gruppe in Umfangsrichtung einen nicht näher bezeichneten Abstand zueinander auf. In den Abstandsraum zwei aufeinander folgende Stützelemente 22, 23 der einen Gruppe greifen die Stützelemente 23 oder 22 der zweiten Gruppe kammartig ein. Wie bereits vorstehend erläutert wurde, besteht aber auch die Möglichkeit, dass die Stützelemente 22, 23 einander gegenüberliegen und sich hierbei die freien Enden berühren oder aber einen Abstand aufweisen, durch den die Mittelebene 4 des Rades 1 hindurchgeht. Fig. 3 shows a portion of the rim 1 in a plan view. It can be seen that the support elements 22, 23 are formed tongue-shaped or Kragarmartig and that the gap 16 between the support members 22, 23 is narrow and uniformly wide. As in particular from Fig. 3 can be removed, the support elements 22 or 23 of the first and second group in the circumferential direction an unspecified distance from each other. In the distance space two successive support members 22, 23 of a group engage the support members 23 or 22 of the second group like a comb. However, as already explained above, there is also the possibility that the support elements 22, 23 lie opposite one another and in this case touch the free ends or have a spacing through which the center plane 4 of the wheel 1 passes.

Gemäß einer Ausführungsvariante ist vorgesehen, dass die Lauffläche 9 einstückig mit den Stützelementen 22, 23 ausgebildet ist und vorzugsweise aus dem gleichen Material besteht.According to one embodiment, it is provided that the running surface 9 is formed integrally with the support elements 22, 23 and preferably consists of the same material.

Die Fig. 4 zeigt eine weitere Ausführung die nicht Teil der Erfindung ist bei der die Felgenhälften 2, 3 im Wesentlichen scheibenförmig ausgebildet sind. An der ersten Felgenhälfte 2 ist ein Nabenabschnitt 2a einstückig angeformt, der zwei Wälzlager 24, 25 aufnimmt. Die andere Felgenhälfte 3 sitzt auf einer Nut 29 des Nabenabschnitts 2a auf.The Fig. 4 shows a further embodiment which is not part of the invention in which the rim halves 2, 3 are formed substantially disc-shaped. On the first rim half 2, a hub portion 2a is integrally formed, which receives two rolling bearings 24, 25. The other rim half 3 is seated on a groove 29 of the hub portion 2a.

Im Bereich des äußeren Umfangs der Felgenhälften 2, 3 ragen jeweils die Stützelemente 22, 23 in Axialrichtung kragarmartig vor. Die Stützelemente 22, 23 weisen im Bereich der Lagerabschnitte 12, 13 an der Außenseite jeweils eine Ausnehmung 18, 19 auf, die insgesamt eine umlaufende unterbrochene Nut auszubilden und die dazu vorgesehen sind, einen Wulst 26, 27 des Rades 6 aufzunehmen. Die Stützelemente 22, 23 tragen unter Vorspannung die Innenfläche 28 des Reifens 6. Insgesamt ergibt dieser Aufbau eine in sich verspannte und kompakte Baugruppe, da beispielsweise der Reifen 6 durch die beiden Wulste 26, 27 die Stützelemente 22, 23 zusammengehalten werden. Am äußeren Umfang der Felgenhälften 2, 3 sind Schultern 30, 31 ausgebildet, die den Reifen 6 abstützen und die Stabilität erhöhen.In the region of the outer circumference of the rim halves 2, 3, in each case the support elements 22, 23 protrude cantilever-like in the axial direction. The support elements 22, 23 have in the region of the bearing portions 12, 13 on the outer side in each case a recess 18, 19 which form a total circumferential interrupted groove and which are intended to receive a bead 26, 27 of the wheel 6. The support elements 22, 23 carry under bias the inner surface 28 of the tire 6. Overall, this structure results in a tense and compact assembly, since for example the tire 6 by the two beads 26, 27th the support elements 22, 23 are held together. On the outer periphery of the rim halves 2, 3 shoulders 30, 31 are formed, which support the tire 6 and increase the stability.

Die Ausführungsvariante von Fig. 5 unterscheidet sich von den oben beschriebenen dadurch, dass die einzelnen Stützelemente 22, 23 nicht in Umfangsrichtung mit oder ohne Abstand zwischen den einzelnen aufeinander folgenden Stützelementen 22, 23 nebeneinander sondern übereinander angeordnet sind. Das in Fig. 5 dargestellte Stützelement 22 der ersten Gruppe liegt unterhalb eines Stützelements 23 der zweiten Gruppe und stützt dieses. Bei den benachbarten Paaren von Stützelementen 22, 23, die hier nicht detailliert ersichtlich sind, ist es umgekehrt, hier stützt ein Stützelement 23 der zweiten Gruppe ein Stützelement 22 der ersten Gruppe. Grundsätzlich können auch alle Stützelemente 22 oder 23 der einen Gruppe auf bzw. unter den Stützelementen 23 oder 22 der anderen Gruppe angeordnet werden.The variant of Fig. 5 differs from those described above in that the individual support elements 22, 23 are not arranged in the circumferential direction with or without spacing between the individual successive support elements 22, 23 next to each other but one above the other. This in Fig. 5 illustrated support member 22 of the first group is below a support member 23 of the second group and supports this. In the adjacent pairs of support members 22, 23, which are not detailed here, it is vice versa, here supports a support member 23 of the second group, a support member 22 of the first group. In principle, all support elements 22 or 23 of the one group can also be arranged on or under the support elements 23 or 22 of the other group.

Die Stützelemente 22, 23 weisen Anschlagvorsprünge 20, 21 auf, die das Einfedern begrenzen, indem sie einen Anschlag für die Spitze des gegenüberliegenden Stützelements 23, 22 bilden.The support elements 22, 23 have stop projections 20, 21 which limit the compression by forming a stop for the tip of the opposite support member 23, 22.

Die im Zusammenhang mit den Fig. 4 und Fig. 5 erläuterte Ausführungsformen des erfindungsgemäßen Rades können dadurch gefertigt werden, dass zunächst die ersten Felgenhälfte 2 sowie die zweite Felgenhälfte 3 mit den daran einstückig angeformten Stützelementen 22, 23 durch ein Spritzgussverfahren hergestellt werden. Anschließend kann das Rad 6 auf die erste oder die zweite Felgenhälfte 2, 3 aufgeschoben werden. Daraufhin können die beiden Felgenhälften 2 und 3 mit den zueinander weisenden Stützelementen 22, 23 in der Weise aufgesteckt werden, dass die zweite Felgenhälfte 3 in die umlaufende Nut 29 der ersten Felgenhälfte 2 eintaucht und ggf. gleichzeitig die Stützelemente 23 der zweiten Felgenhälfte 3 in die Zwischenräume zwischen zwei aufeinander folgende Stützelemente 22 der ersten Felgenhälfte kammartig eingreifen oder, wie insbesondere in Fig. 5 gezeigt, auf diese auf- bzw. untergeschoben werden. Anschließend können die beiden Felgenhälften 2, 3 lösbar miteinander verbunden werden, beispielsweise durch eine Schraubverbindung.The in connection with the 4 and FIG. 5 explained embodiments of the wheel according to the invention can be made by first the first rim half 2 and the second rim half 3 with the integrally formed thereon supporting elements 22, 23 are produced by an injection molding process. Subsequently, the wheel 6 can be pushed onto the first or the second rim half 2, 3. Then, the two rim halves 2 and 3 with the mutually facing support members 22, 23 are plugged in such a way that the second rim half 3 dips into the circumferential groove 29 of the first rim half 2 and possibly simultaneously the support members 23 of the second rim half 3 in the Interspaces between two consecutive support members 22 of the first rim half engage comb-like or, in particular in Fig. 5 shown on this or be pushed on. Subsequently, the two rim halves 2, 3 are releasably connected to each other, for example by a screw connection.

Die vorliegende Erfindung ermöglicht es, ein Rad mit optimalen Fahreigenschaften in einfacher Weise herzustellen und gleichzeitig extrem leicht zu bauen. Gleichzeitig werden unerwünschte Schwingungen weitgehend unterdrückt.The present invention makes it possible to manufacture a wheel with optimum driving characteristics in a simple manner and at the same time extremely easy to build. At the same time unwanted vibrations are largely suppressed.
