Description

Die Erfindung bezieht sich auf ein Rad der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a wheel of the type mentioned in the preamble of claim 1.

Solche Räder werden vorteilhaft in Inline Skates verwendet, die als Sportgerät und für den Freizeitgebrauch eine große Verbreitung gefunden haben.Such wheels are advantageously used in inline skates that are used as sports equipment and for the Recreational use have become widespread.

Aus DE-U1-80 20 620 sind Rollen für Rollschuhe bekannt, die einen aus zwei Teilen bestehenden Nabenring aufweisen, der mit einem Mantel umspritzt ist, dessen äußere Umfangsfläche die Lauffläche darstellt Vor dem Zusammenfügen der beiden Nabenteile wird ein Kugellager eingesetzt.From DE-U1-80 20 620 rollers for roller skates are known, one of two parts have existing hub ring, which is encapsulated with a jacket, the outer Circumferential surface represents the tread Before the two hub parts are joined a ball bearing is used.

Aus US-A-5,470,086 sind Inline Skates bekannt, deren Räder in ähnlicher Weise aus mehreren Teilen zusammengesetzt sind. Zwischen zwei Nabenteile ist einerseits ein Kugellager und andererseits eine Scheibe, die von einem Reifen mit der Lauffläche umgeben ist, einfügbar. Alle diese Teile werden mittels Schrauben und Muttern zusammenmontiert. Das so montierte Rad wird seinerseits mit einer Achse im Laufwerk montiert, wobei die Achse ihrerseits durch eine Verschraubung im Laufwerk gehalten wird.From US-A-5,470,086 inline skates are known, the wheels of which are similarly made of several Parts are assembled. Between two hub parts there is a ball bearing and on the other hand, a disc surrounded by a tire with the tread insertable. All these parts are assembled using screws and nuts. The wheel so assembled is in turn mounted with an axis in the drive, the axis itself being replaced by a Screw connection is held in the drive.

In der US-PS 5,484,164 ist gleichfalls ein ähnliches Gerät skizziert und in seinem grundsätzlichen Aufbau beschrieben. Üblicherweise weist jeder Schuh ein Laufwerk auf, in dem vier einzelne Räder gelagert sind. Diese Räder sind um eine Achse drehbar, wobei die Achse in das Laufwerk fest eingeschraubt wird. Die Räder bestehen aus einem Radkörper, in das Kugellager eingesetzt sind, die ihrerseits mit der Achse verbunden sind. Die Radkörper bestehen üblicherweise aus einem Stück.A similar device is also outlined in US Pat. No. 5,484,164 and in its basic structure described. Each shoe usually has a drive in which four individual wheels are stored. These wheels are rotatable about an axis, the Axis is screwed into the drive. The wheels consist of a wheel body, in the ball bearings are used, which in turn are connected to the axis. The wheel center usually consist of one piece.

Aus US-A-5 308 152 sind Räder für Inline-Skates bekannt die aus zwei Radscheiben und einem Radreifen bestehen. Die Radscheiben sind aber mittels Schrauben verbunden. Deswegen ist das so montierte Rad ohne Werkzeug nicht demontierbar.From US-A-5 308 152 wheels for inline skates are known which consist of two wheel disks and a wheel tire. The Wheel disks are connected by screws. That is why it is so The assembled wheel cannot be removed without tools.

Solche Inline Skates werden vielfach auf normalen Straßen und Gehwegen benutzt, weil spezielle Sportbahnen sehr selten anzutreffen sind. Während die wenigen Sportbahnen, die meist dem Training akrobatischer Leistungen dienen, einen speziellen Belag aufweisen, muß auf Straßen und Gehwegen der übliche Belag hingenommen werden. Beläge für Straßen und Gehwege werden vorwiegend als Asphalt ausgeführt, der in der Regel eine relativ rauhe Oberfläche aufweist. Bedingt dadurch entsteht beim Gebrauch der Inline Skates ein starker Verschleiß an den Rädern. Bei häufigem Gebrauch sind die Räder schnell verschlissen.Such inline skates are often used on normal streets and sidewalks because special sports tracks are very rare. While the few sports tracks that mostly used for training acrobatic performances, must have a special surface the usual surface is accepted on streets and sidewalks. Road and road surfaces Sidewalks are mostly constructed as asphalt, which is usually a relatively rough one Surface. As a result, a stronger one is created when using the inline skates Wear on the wheels. With frequent use, the wheels wear out quickly.

Der Erfindung liegt die Aufgabe zugrunde, den vorbekannten Stand der Technik so weiterzubilden, daß der im Gebrauch erheblichem Verschleiß ausgesetzte Reifen leicht auswechselbar ist.The invention is based, so the prior art, the task to further develop that the tire exposed to considerable wear easily is interchangeable.

Die genannte Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den abhängigen Ansprüchen.According to the invention, the stated object is achieved by the features of claim 1. Advantageous refinements result from the dependent claims.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. An exemplary embodiment of the invention is described in more detail below with reference to the drawing explained.

In der Fig. 1 bedeutet 1 ein Rad, das mittels einer Achse 2 in Rahmenteilen 3 eines Inline Skates angeordnet ist. Die Achse 2 ist nach dem Stand der Technik aus zwei Einzelteilen aufgebaut, nämlich aus einem ersten Achsteil 4 und einem zweiten Achsteil 5. Beide Achsteile 4, 5 weisen an einem der Enden einen linsenkopfförmigen Kragen 6 auf, deren jeder im Zentrum eine Öffnung 7 aufweist. Diese Öffnung 7 hat die Form eines Innensechskants. Damit sind Demontage und Montage von Rädern 1 möglich.In Fig. 1, 1 means a wheel, which by means of an axle 2 in frame parts 3 of an inline Skates is arranged. According to the prior art, axis 2 consists of two individual parts constructed, namely from a first axle part 4 and a second axle part 5. Both Axle parts 4, 5 have at one of the ends a lenticular collar 6, each of which has an opening 7 in the center. This opening 7 has the shape of a hexagon socket. This enables disassembly and assembly of wheels 1.

Am dem Kragen 6 gegenüberliegenden Ende weist das erste Achsteil 4 eine Bohrung 8 auf, in die ein Innengewinde 9 geschnitten ist. Entsprechend weist das zweite Achsteil 5 am dem Kragen 6 gegenüberliegenden Ende einen Stift 10 auf, der mit einem Außengewinde 11 versehen ist. Durch die Gewinde 9, 11 sind die beiden Achsteile 4, 5 miteinander verschraubbar. In diesem verschraubten Zustand bilden sie die Achse 2.At the end opposite the collar 6, the first axle part 4 has a bore 8 in which has an internal thread 9 cut. Accordingly, the second axis part 5 on the Collar 6 opposite end on a pin 10 which has an external thread 11 is provided. Through the threads 9, 11, the two axle parts 4, 5 are together screwed. In this screwed state, they form axis 2.

Das Rad 1 besteht aus zwei Radscheiben 20 und einem diese umgebenden und verbindenden Radreifen 21, der seinerseits aus einem Träger 22 und einem Laufkörper 23 zusammengesetzt ist. Dabei weist der Träger 22 Formstücke 24 auf in die Vertiefungen 25 des Laufkörpers eingreifen. Die Formstücke 24 und die Vertiefungen 25 sind räumlich so gestaltet, daß sie das Verrutschen des Laufkörpers 23 auf dem Träger 22 verhindern, und zwar sowohl in Umfangsrichtung, d.h. in der Laufrichtung, als auch in seitlicher Richtung, d.h. quer zur Laufrichtung. Die Formstücke 24 sind am Träger 22 unmittelbar angeformt. So kann der Träger 22 beispielsweise ein entsprechend gestaltetes Guß-, Preß-, Spritz- oder Druckgußteil sein, wobei metallische Werkstoffe, z.B. eine Aluminiumlegierung, oder nichtmetallische Werkstoffe, z.B. glasfaserverstärktes Polyurethan, Anwendung finden können. Die Vertiefungen des Laufkörpers 23 ergeben sich zwangsweise, wenn die Herstellung des Radreifen 21 auf eine solche Weise erfolgt, daß der Träger 22 in einem entsprechenden Werkzeug umspritzt wird. Dabei wird eine innige Verbindung zwischen Träger 22 und Laufkörper 23 erreicht. Analog zu den Formstücken 24 und Vertiefungen 25 sind auch die Berührungsflächen von Radscheiben 20 und Träger 22 gestaltet. Damit wird erreicht, daß das Verrutschen des Radreifens 21 auf den Radscheiben 20 vermieden wird.The wheel 1 consists of two wheel disks 20 and a surrounding and connecting them Wheel tire 21, which in turn is composed of a carrier 22 and a running body 23 is. The carrier 22 has shaped pieces 24 in the recesses 25 of the barrel intervention. The fittings 24 and the recesses 25 are spatially designed so that they Prevent slipping of the barrel 23 on the carrier 22, both in Circumferential direction, i.e. in the running direction as well as in the lateral direction, i.e. across to Direction. The shaped pieces 24 are molded directly onto the carrier 22. So he can Carrier 22, for example, a suitably designed casting, pressing, injection molding or die casting where metallic materials, e.g. an aluminum alloy, or non-metallic Materials, e.g. glass fiber reinforced polyurethane, can be used. The Recesses of the barrel body 23 are inevitable when the manufacture of the Wheel tire 21 is carried out in such a way that the carrier 22 in a corresponding Tool is overmolded. An intimate connection between carrier 22 and Running body 23 reached. Analog to the fittings 24 and recesses 25 are also Contact surfaces of wheel disks 20 and carrier 22 designed. This ensures that Slipping of the wheel tire 21 on the wheel disks 20 is avoided.

In einer passenden zentrischen Vertiefung jeder Radscheibe 20 ist ein Kugellager 26 eingepaßt. Der innere Ring des Kugellagers 26 ist mit der Achse 2 verbunden, beispielsweise durch einen eng tolerierten Schiebesitz. Die Kugellager 26 können vorteilhaft mittels einer die Achse 2 umgebenden Distanzhülse 27 im richtigen Abstand gehalten sein. Diese Funktion kann aber auch von den Radscheiben 20 mit übernommen werden. A ball bearing 26 is fitted in a suitable central recess in each wheel disk 20. The inner ring of the ball bearing 26 is connected to the axis 2, for example by a narrowly tolerated sliding seat. The ball bearings 26 can advantageously be by means of the axis 2 surrounding spacer sleeve 27 be held at the correct distance. This function can also be taken over by the wheel disks 20.

Fig. 2 zeigt eine Seitenansicht einer Radscheibe 20. Ihre außere Begrenzung 30 bildet die Auflagefläche für den Radreifen 21 (Fig. 1). Die Radscheibe 20 weist in ihrem Zentrum eine Vertiefung 31 auf, die der Aufnahme des Kugellagers 26 (Fig. 1) dient. Das Maß der Vertiefung 31 ist deshalb auf den Außendurchmesser des Kugellagers 26 abgestimmt, wobei auch hier ein eng tolerierter Schiebesitz vorgesehen werden kann. Die Radscheibe 20 weist außerdem eine Anzahl von Öffnungen 32 auf. Die Form dieser Öffnungen 32 kann in weiten Grenzen gewählt werden und ganz besonders auf ästhetische Gesichtspunkte Rücksicht nehmen. Durch diese Öffnungen 32 werden in der Radscheibe 20 gleichzeitig Speichen 33 gebildet, deren Anzahl der Anzahl der Öffnungen entspricht. Da die Speichen 33 die auftretenden statischen und dynamischen Kräfte aufzunehmen haben, sind bei deren Bemessung diese Kräfte gebührend zu berücksichtigen. Entsprechend reduziert sich der Freiraum für die Gestaltung der Öffnungen 32.Fig. 2 shows a side view of a wheel disc 20. Its outer boundary 30 forms the Support surface for the wheel tire 21 (Fig. 1). The wheel disc 20 has one in its center Indentation 31, which serves to receive the ball bearing 26 (FIG. 1). The measure of Recess 31 is therefore matched to the outer diameter of the ball bearing 26, wherein a closely tolerated sliding seat can also be provided here. The wheel disc 20 has also a number of openings 32. The shape of these openings 32 can vary widely Boundaries are chosen, and special consideration is given to aesthetic considerations to take. Spokes 33 are simultaneously in the wheel disc 20 through these openings 32 formed, the number of which corresponds to the number of openings. Since the spokes 33 the occurring static and dynamic forces have to be absorbed by them Dimensioning to take due account of these forces. The is reduced accordingly Free space for the design of the openings 32.

Das die Vertiefung 31 umgebende Material der Radscheibe 20 bildet eine Radnabe 34, die in die Speichen 33 übergeht. Am anderen Ende der Speichen 33 ist das Material der Radscheibe 20 bis zur äußeren Begrenzung 30 als Felge 35 ausgebildet. Die Dicke von Radscheibe 20, Radnabe 34, Speichen 33 und Felge 35 wird durch die statischen und dynamischen Kräfte bestimmt. Deren Bemessung liegt entsprechend im Ermessen des Fachmanns. Die Radscheiben 20 werden vorteilhaft als Guß- oder Druckgußteile hergestellt, beispielsweise aus einer Aluminiumlegierung. Es ist aber auch möglich, die Radscheiben 20 aus hoch belastbarem Kunststoff nach den jeweils bestgeeigneten Herstellungsverfahren zu fertigen.The material of the wheel disk 20 surrounding the recess 31 forms a wheel hub 34 which is shown in FIG the spokes 33 merges. At the other end of the spokes 33 is the material of the Wheel disc 20 is formed as a rim 35 up to the outer boundary 30. The thickness of Wheel disc 20, wheel hub 34, spokes 33 and rim 35 is by the static and dynamic forces determined. Their assessment is accordingly at the discretion of the Expert. The wheel disks 20 are advantageously produced as cast or die-cast parts, for example from an aluminum alloy. However, it is also possible to remove the wheel disks 20 highly resilient plastic according to the most suitable manufacturing process finished.

Im Zentrum der Radscheibe 20 ist eine durchgehende Bohrung 36 vorhanden, die der Durchführung der Achse 2 dient. Ist eine Distanzhülse 27 wie in Fig. 1 vorgesehen, so ist die Bohrung 36 etwas größer als der Außendurchmesser der Distanzhülse 27. Wird auf eine Distanzhülse 27 verzichtet, wie noch gezeigt wird, dann ist die Bohrung 36 etwas größer als der Durchmesser der Achse 2.In the center of the wheel disc 20 there is a through hole 36, which the Implementation of axis 2 is used. If a spacer sleeve 27 is provided as in Fig. 1, the Bore 36 slightly larger than the outer diameter of the spacer sleeve 27. Is on a Distance sleeve 27 is omitted, as will be shown, then the bore 36 is slightly larger than the diameter of axis 2.

In der Fig. 3 sind in der Art einer Explosionszeichnung die Bestandteile eines Rades 1 dargestellt. Von links sind dies: Das erste Achsteil 5, das Kugellager 26, eine Radscheibe 20, der Radreifen 21, eine gleiche, aber gegenüber der ersten Radscheibe 20 gewendete Radscheibe 20, ein Kugellager 26 und das zweite Achsteil 4. Gleiche Bezugszahlen bezeichnen dabei in allen Figuren gleiche Teile. Jede Radscheibe 20 weist an der einen Seite, die im Montagezustand die Außenseite bildet, eine Vertiefung 31 auf, in die das Kugellager 26 einsetzbar ist. Die Vertiefung 31 ist in Tiefe und Durchmesser genau auf die Maße des Kugellagers 26 abgestimmt. Um die zentrische Bohrung weist die Radscheibe 20 einen Kragen 37 auf. Durch diesen Kragen 37 wird das Kugellager 26 in axialer Richtung gehalten. Dadurch ist die Distanzhülse 27 entbehrlich. 3 shows the components of a wheel 1 in the manner of an exploded drawing shown. From the left, these are: the first axle part 5, the ball bearing 26, a wheel disc 20, the wheel tire 21, the same, but opposite to the first wheel disc 20 Wheel disc 20, a ball bearing 26 and the second axle part 4. Designate the same reference numerals same parts in all figures. Each wheel disc 20 has on one side, which in the Mounting state forms the outside, a recess 31 into which the ball bearing 26th can be used. The recess 31 is in depth and diameter exactly to the dimensions of the Ball bearings 26 matched. The wheel disc 20 has one around the central bore Collar 37 on. The ball bearing 26 is held in the axial direction by this collar 37. This makes the spacer sleeve 27 unnecessary.

Zusätzlich sind an den Radscheiben 20 zahnartige Rippen 40 angebracht, die sich entlang der inneren Kante 41 der Radscheibe mit Vertiefungen 42 abwechseln. Entsprechende zahnartige Rippen 43 und Vertiefungen 44 sind an den Kanten des Innendurchmessers des Trägers 22 angeformt. Dabei passen die Rippen 40 genau in die Vertiefungen 44 und die Rippen 43 in die Vertiefungen 42. Die entstehende Verbindung beim Zusammenbau von Radscheiben 20 und Träger 22 entspricht dabei jener nach der Art von Nut und Feder bei Holzverbindungen. Durch diese Gestaltung wird erreicht, daß der Radreifen 21 gegenüber den Radscheiben 20 nicht in Umfangsrichtung verrutschen kann. Gleichzeitig wird erreicht, daß sich die beiden Radscheiben 20 nicht gegeneinander verdrehen können.In addition, 20 tooth-like ribs 40 are attached to the wheel disks, which extend along the Alternate inner edge 41 of the wheel disc with indentations 42. Corresponding tooth-like Ribs 43 and depressions 44 are on the edges of the inner diameter of the carrier 22 formed. The ribs 40 fit exactly into the depressions 44 and the ribs 43 into the Wells 42. The resulting connection when assembling wheel disks 20 and Carrier 22 corresponds to that of the tongue and groove type in wood connections. By this design ensures that the wheel tire 21 is not in relation to the wheel disks 20 Circumferential direction can slip. At the same time it is achieved that the two Wheel disks 20 can not twist against each other.

Das erfindungsgemäße Rad 1 ist so ausgelegt, daß seine Einzelteile durch den Benutzer demontierbar und einzeln auswechselbar sind. Die Achsteile 4 und 5 gehören in der Regel zum Lieferumfang der Inline Skates und können bei einem Radwechsel wieder verwendet werden. Das gilt im Prinzip auch für die Kugellager 26. Es ist jedoch möglich, daß der Benutzer der Inline Skates solche Kugellager 26 einzeln kauft, beispielsweise solche einer besonders guten Qualität, wenn er hohe Anforderungen an die Inline Skates stellt.The wheel 1 according to the invention is designed so that its individual parts by the user can be disassembled and replaced individually. The axle parts 4 and 5 usually belong to the Scope of delivery of the inline skates and can be used again when changing wheels. In principle, this also applies to the ball bearings 26. However, it is possible that the user of the Inline skates buy such ball bearings 26 individually, for example those of a particularly good one Quality if he places high demands on the inline skates.

Sind bei erfindungsgemäßen Rädern 1 durch starken Gebrauch die Radreifen 21, nämlich besonders die Laufkörper 23, stark verschlissen, so bleibt es dem Benutzer erspart, das ganze Rad wegzuwerfen. Er kann einzelne Radreifen 21 nachkaufen. Er demontiert dazu die Achse 2, indem er unter Verwendung von Inbusschlüsseln die beiden Achsteile 4 und 5 auseinanderschraubt. Anschließend kann er das Rad 1 aus den Rahmenteilen 3 (Fig. 1) herausnehmen und ohne Werkzeug demontieren. Unter Verwendung eines neu gekauften Radreifens 21 kann er in diesen von beiden Seiten her je eine Radscheibe 20 einsetzen, die Kugellager 26 in die entsprechenden Vertiefungen 31 in den Radscheiben 20 eindrücken und das so montierte Rad 1 unter Verwendung der Achsteile 4 und 5 wieder einbauen.In the wheels 1 according to the invention, the wheel tires 21, namely, are used heavily especially the barrel 23, badly worn, so the user is spared the whole Throwing the wheel away. He can buy individual wheel tires 21. To do this, he disassembles axis 2, by using the two axle parts 4 and 5 using Allen keys apart screwed. Then he can the wheel 1 from the frame parts 3 (Fig. 1) remove and disassemble without tools. Using a newly purchased one Wheel tire 21, he can use a wheel disk 20 in each of these from both sides Press ball bearing 26 into the corresponding recesses 31 in the wheel disks 20 and Reinstall the wheel 1 assembled in this way using axle parts 4 and 5.

Vorteilhaft weist die äußere Begrenzung des Lautkörpers 23 einen Radius R auf, der deutlich größer ist als die Hälfte der Breite B des Trägers 22. Dadurch wird erreicht, daß die Lauffläche seitlich zur Drehrichtung der Räder 1 weniger stark gekrümmt ist. Das bedeutet auch, daß die Auflagefläche auf der Fahrbahn größer ist und damit der spezifische Druck kleiner ist. Das bietet den Vorteil, daß der Verschleiß am Laufkörper 23 geringer wird.The outer boundary of the loudspeaker 23 advantageously has a radius R that is clear is greater than half the width B of the carrier 22. This ensures that the tread laterally to the direction of rotation of the wheels 1 is less curved. It also means that the Contact area on the road is larger and the specific pressure is smaller. The offers the advantage that the wear on the barrel 23 is less.

Die Erfindung bietet auch die Möglichkeit, verschiedene Radreifen 21 feilzuhalten, die sich in Material und Profilierung des Laufkörpers 23 unterscheiden. So können auch unterschiedliche Härtegrade des Laufkörpers 23 zum Einsatz kommen. Um ästhetischen Gesichtspunkten zu genügen, können auch unterschiedliche Farben zum Einsatz kommen. Durch die Erfindung ist es somit möglich, die Räder 1 schnell und kostengünstig an unterschiedliche Bedürfnisse anzupassen, so etwa an Rennskating, Hockey, Akrobatik usw.The invention also offers the possibility of holding different wheel tires 21, which can be found in Differentiate material and profile of the barrel 23. So can also be different Hardness levels of the barrel body 23 are used. To aesthetic aspects too different colors can be used. By the invention is it is thus possible to adapt the wheels 1 quickly and inexpensively to different needs to adapt, for example to racing skating, hockey, acrobatics etc.

Durch die Erfindung wird auch erreicht, daß im Inneren eines Rades 1 ein freier Raum verbleibt, der für unterschiedliche Zwecke genutzt werden kann.The invention also ensures that there is a free space inside a wheel 1 remains, which can be used for different purposes.
