Abstract

A roller-ski comprising a longitudinal support (1) provided with a ski binding (5) for securing a ski boot, whereby rubber-tyred rollers (3, 8, 9) are fitted at the front and rear on the longitudinal support (1), a reversing block being provided on one or several of these wheels. In order to provide such a roller-ski with a braking device of simple design, which can be operated by the skier with a body movement normally used in skiing, it is envisaged that in particular the rear rollers (8) are provided on the side facing the adjacent ski with a brake lining (10) laterally fixed to the roller (8) and slightly projecting inwardly on the lateral delimitation (11) of the longitudinal support (1), which delimitation extends in the rolling direction. These lateral delimitations (11) of the longitudinal supports (1) comprise braking counter-surfaces (12) extending roughly parallel to the brake lining (10) of the rollers (8).

Description

Die Erfindung betrifft ein Rollskipaar, bei welchem jeder Ski einen mit einer Bindung für einen Skistiefel versehenen Längsträger aufweist, an welchem vorn und hinten gummibereifte Laufräder gelagert sind, von denen eines oder mehrere mit einer Rücklaufsperre versehen sind.The invention relates to a pair of roller skis, in which each ski has a side member provided with a binding for a ski boot, on which rubber-tired wheels are mounted at the front and rear, one or more of which are provided with a backstop.

Derartige Rollski sind als Sommer-Trainingsgerät für Skilangläufer bekannt. In diesem Falle haben die gummibereiften Laufräder einen verhältnismäßig kleinen Durchmesser und sind dementsprechend nur für ebenes Gelände mit festem Untergrund, beispielsweise für asphaltierte Straßen geeignet. Um derartige Rollski auch abseits von asphaltierten Straßen beispielsweise auf Waldwegen verwenden zu können, ist es auch bekannt, Laufräder mit größerem Durchmesser zu verwenden. Derartig ausgebildete Rollski eignen sich vom Grundsatz her hervorragend für das Fitnesstraining, weil im Vergleich zum Dauerlauf die Gelenke weniger Stoßbelastungen ausgesetzt sind und durch die Armarbeit mit den Skistöcken mehr der gesamte Körper in das Fitnesstraining einbezogen ist.Such roller skis are known as a summer training device for cross-country skiers. In this case, the rubber-tired wheels have a relatively small diameter and are therefore only suitable for flat terrain with a solid surface, for example for asphalt roads. In order to be able to use such roller skis also away from paved roads, for example on forest paths, it is also known to use wheels with a larger diameter. In principle, roller skis designed in this way are outstandingly suitable for fitness training because, compared to endurance running, the joints are less exposed to shock loads and the arm work with the ski poles means that the entire body is more involved in the fitness training.

Ein besonderes Problem bei der Verwendung solcher Rollski besteht darin, die Rollski in abschüssigem Gelände abbremsen zu können. In der Patentliteratur existiert eine große Zahl von Vorschlägen für auf die Räder einwirkende Bremsvorrichtungen, die mit einem Skistock, über ein Seil, von Hand, mit der Ferse oder der Wade des Läufers ausgelöst werden. Alle diese Bremsvorrichtungen sind jedoch zu kompliziert im Aufbau und behindern den natürlichen Bewegungsablauf, so daß derartige Rollski mit Bremseinrichtung kaum Verbreitung gefunden haben.A particular problem with the use of such roller skis is being able to brake the roller skis in sloping terrain. A large number of proposals exist in the patent literature for brake devices acting on the wheels, which are triggered with a ski pole, over a rope, by hand, with the heel or calf of the runner. However, all of these braking devices are too complicated in construction and hinder the natural movement sequence, so that roller skis of this type with braking device have hardly been used.

Aus der DE-OS 28 23 152 ist es bekannt, den Träger um eine in Laufrichtung verlaufende Achse kippbar auszubilden und mit auf die Laufräder einwirkenden Bremsbacken zu versehen. Hierdurch soll es möglich sein, eine Bremswirkung durch Verkanten des Rollski zu erzielen, das heißt also durch eine Bewegung, die man auch beim normalen Skilauf kennt. Diese Bremseinrichtung hat jedoch den Nachteil, daß es in unebenem Gelände für den Läufer ungewollt und überraschend zu Bremsvorgängen kommt, wenn das Gelände quer zur Fahrtrichtung geneigt verläuft oder entsprechende Unebenheiten im Untergrund vorhanden sind. Solche ungewollten und für den Läufer unvorhersehbaren Bremsvorgänge können zu unangenehmen Stürzen führen.From DE-OS 28 23 152 it is known to design the carrier to be tiltable about an axis running in the direction of travel and to provide it with brake shoes acting on the wheels. This should make it possible to achieve a braking effect by tilting the roller ski, that is to say by means of a movement that is also known in normal skiing. However, this braking device has the disadvantage that unexpected and unexpected braking operations occur for the runner when the terrain is inclined transversely to the direction of travel or there are corresponding bumps in the ground. Such unwanted and unpredictable braking processes can lead to unpleasant falls.

Aufgabe der Erfindung ist es deshalb, die Rollski der eingangs genannten Art dahingehend weiterzubilden, daß sie ohne aufwendige Bremseinrichtung durch einen dem Skiläufer bekannten Bewegungsvorgang in abschüssigem Gelände gezielt abgebremst werden können.The object of the invention is therefore to further develop the roller skis of the type mentioned at the outset in such a way that they can be braked in a sloping terrain without an expensive braking device by means of a movement process known to the skier.

Zur Lösung dieser Aufgabe schlägt die Erfindung ausgehend von dem Rollskipaar der eingangs genannten Art vor, daß jeder Ski hinten zwei parallele Laufräder aufweist, von denen das innere Laufrad an der jeweils dem benachbarten Rollski zugewandten Seite mit einem seitlich an dem Laufrad befestigten Bremsbelag versehhen ist, wobei der Bremsbelag geringfügig nach innen über die sich in Laufrichtung erstreckende, innere seitliche Begrenzung des Längsträgers hinaussteht und daß diese seitliche Begrenzung des Längsträgers mit einer Gegenbremsfläche versehen ist, die im wesentlichen parallel zu dem Bremsbelag an dem inneren Laufrad verläuft.To achieve this object, the invention proposes, starting from the pair of roller skis of the type mentioned, that each ski has two parallel rear wheels, of which the inner wheel on the side facing the adjacent roller ski is provided with a brake lining attached to the side of the wheel, the brake lining projecting slightly inwards beyond the inner lateral boundary of the longitudinal member extending in the direction of travel and that this lateral boundary of the longitudinal member is provided with a counter braking surface which runs essentially parallel to the brake lining on the inner impeller.

Die Bremsbeläge an den Laufrädern und die Gegenbremsflächen an den Längsträgern ermöglichen es dem Läufer, einen in der Bremswirkung genau dosierten Bremsvorgang durchzuführen, indem die Innenseiten der Rollski bei geringfügigem Versatz in Laufrichtung gegen einandergepreßt werden. Hierzu genügt es, die Rollski ähnlich wie beim Abfahrtsskilauf mit normalen Ski etwa um etwas weniger als eine Fußlänge versetzt und mit zusammengedrückten Knien gegeneinander zu pressen. Eine besonders intensive Bremswirkung ergibt sich im Bedarfsfalle, wenn man die Ski in Laufrichtung während des Bremsvorganges um etwas weniger als den Durchmesser der Laufräder versetzt. In diesem Fall reiben die gegenläufig bewegten Bremsbeläge an den Laufrädern unmittelbar aneinander, wodurch sich eine besonders starke Bremswirkung ergibt.The brake pads on the wheels and the counter-braking surfaces on the side members enable the runner to carry out a braking process that is precisely metered in the braking effect by pressing the inner sides of the roller skis against each other with a slight offset in the running direction. To do this, it is sufficient to offset the roller skis by a little less than a foot length, similar to normal downhill skiing, and press them together with your knees pressed together. A particularly intensive braking effect is obtained if the skis are moved slightly less than the diameter of the wheels in the direction of travel during the braking process. In this case, the oppositely moving brake pads rub against each other directly on the wheels, which results in a particularly strong braking effect.

Um die Bremsbeläge bzw. die Gegenbremsflächen, die Verschleißteile sind, im Bedarfsfall austauschen zu können ist weiterhin vorgesehen daß die Bremsbeläge und/oder die Gegenbremsflächen auswechselbar an den Laufrädern bzw. der inneren seitlichen Begrenzung des Längsträgers befestigt sind.In order to be able to replace the brake linings or the counter-braking surfaces, which are wearing parts, if necessary, it is further provided that the brake linings and / or the counter-braking surfaces are exchangeably fastened to the impellers or the inner lateral boundary of the side member.

Um dem Rollski während des Bremsvorganges eine gute Stabilität gegen Verkanten nach außen zu geben, ist weiterhin vorgesehen, daß jeder Ski vorn eines und hinten zwei Parallele Laufräder aufweist, wobei der Längsträger am rückwärtigen Ende in horizontaler Ebene derart seitlich abgekröpft ausgebildet ist, daß einerseits das innere, hintere Laufrad in Laufrichtung unmittelbar hinter dem Absatz des Skistiefels und andererseits das äußere hintere Laufrad seitlich nach außen versetzt hinter dem Absatz des Skistiefels angeordnet sind. Diese Anordnung der Laufräder stellt auch sicher, daß die inneren Laufräder beim Lauf nicht so leicht miteinander in Berührung kommen.In order to give the roller skis good stability against canting to the outside during the braking process, it is further provided that each ski has one parallel and two parallel wheels at the front, with the side member being cranked sideways at the rear end in a horizontal plane in such a way that on the one hand the inner, rear wheel in the running direction immediately behind the heel of the ski boot and on the other hand the outer rear wheel offset laterally outwards behind the heel of the ski boot. This arrangement of the impellers also ensures that the inner impellers do not come into contact with each other so easily during the run.

Zweckmäßig ist weiterhin der Längsträger derart zusätzlich nach unten abgekröpft, daß die Standfläche des Skistiefels unterhalb der Achsen der Laufräder liegt. Hierdurch befinden sich die Rollski immer in einer stabilen Gleichgewichtslage was insbesondere während des Bremsvorganges, bei welchem von der Seite her Kräfte auf die Rollski einwirken, von großem Vorteil ist.Advantageously, the side member is additionally bent downwards in such a way that the base of the ski boot lies below the axes of the wheels. As a result, the roller skis are always in a stable equilibrium position, which is particularly advantageous during the braking process, in which forces act on the roller skis from the side.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Es zeigen:

  • Fig 1 Einen Rollski gemäß der Erfindung in Draufsicht;
  • Fig. 2 einen Rollski gemäß der Erfindung in Seitenansicht.
An embodiment of the invention is explained below with reference to the drawing. Show it:
  • 1 shows a roller ski according to the invention in plan view;
  • Fig. 2 shows a roller ski according to the invention in side view.

In der Zeichnung ist der Längsträger mit dem Bezugszeichen 1 bezeichnet. Der Längsträger 1 ist am vorderen Ende gegabelt ausgebildet und mit einem um eine Achse 2 drehbaren, gummibereiften Laufrad 3 versehen. Im mittleren Bereich ist der Längsträger 1 mit einer Trittfläche 4 für einen nicht näher dargestellten Skistiefel ausgebildet, der mittels einer Bindung 5 in an sich bekannter Weise an dem Längsträger 1 festlegbar ist.In the drawing, the longitudinal member is designated by the reference number 1. The side member 1 is formed forked at the front end and provided with a rubber wheel 3 rotatable about an axis 2. In the central area, the side member 1 is formed with a step surface 4 for a ski boot, not shown, which can be fixed to the side member 1 in a manner known per se by means of a binding 5.

Am hinteren Ende ist der Längsträger 1 seitlich nach außen abgekröpft. Am abgekröpften Ende 6 sind mittels einer Achse 7 zwei parallel zueinander verlaufende, gummibereifte Laufräder 8 und 9 befestigt. Dabei verläuft das an der Innenseite des Rollski angeordnete Laufrad 8 unmittelbar hinter dem Absatz des Skistiefels, während das äußere hintere Laufrad 9 seitlich nach außen versetzt hinter dem Absatz des Skistiefels angeordnet ist.At the rear end, the side member 1 is bent laterally outwards. At the bent end 6, two rubber tires 8 and 9 running parallel to each other are attached by means of an axis 7. The impeller 8 arranged on the inside of the roller ski runs directly behind the shoulder of the ski boot, while the outer rear impeller 9 is arranged laterally offset to the outside behind the shoulder of the ski boot.

Wie aus Fig. 2 erkennbar ist, ist der Längsträger 1 derart nach unten abgekröpft ausgebildet, daß die Trittfläche 4 unterhalb der Achsen 2 und 7 der Laufräder 3, 8 und 9 liegt. Zur Versteifung ist der Längsträger 1 weiterhin mit sich in dessen Längsrichtung erstreckenden Verstärkungsrippen versehen. Den Achsen 2 und 7 der Laufräder 3, 8 und 9 sind weiterhin in der Zeichnung nicht näher dargestelltes Rücklaufsperren zugeordnet, deren Haltekraft gegebenenfalls einstellbar ist.As can be seen from Fig. 2, the side member 1 is bent so down that the tread 4 is below the axes 2 and 7 of the wheels 3, 8 and 9. For reinforcement, the longitudinal beam 1 is further provided with reinforcing ribs extending in its longitudinal direction. The axes 2 and 7 of the wheels 3, 8 and 9 are also assigned backstops, not shown in the drawing, whose holding force can be adjusted if necessary.

Erfindungsgemäß ist das hintere Laufrad 8 an der dem benachbarten Rollski (nicht dargestellt) zugewandten Seite mit einem seitlich an dem Laufrad 8 befestigten Bremsbelag 10 versehen, der geringfügig nach innen über die sich in Laufrichtung erstreckende, innere seitliche Begrenzung 11 des Längsträgers 1 hinaussteht. Der Bremsbelag 10 ist ringförmig ausgebildet und ist entweder einstückig mit dem Gummireifen des Laufrades 8 verbunden oder seitlich an diesem Gummireifen angeklebt, so daß er im Bedarfsfall ersetzt oder ausgewechselt werden kann. Weiterhin ist die innere seitliche Begrenzung 11 des Längsträgers 1 mit Gegenbremsflächen 12 versehen, die im wesentlichen parallel zu den Bremsbelägen 10 an den Laufrädern 8 verlaufen. Auch diese Gegenbremsflächen 12 sind im Bedarfsfalle auswechselbar befestigt.According to the invention, the rear wheel 8 is provided on the side facing the adjacent roller ski (not shown) with a brake lining 10 which is laterally attached to the wheel 8 and which projects slightly inward beyond the inner lateral boundary 11 of the side member 1 which extends in the running direction. The brake pad 10 is ring-shaped and is either integrally connected to the rubber tire of the impeller 8 or glued to the side of this rubber tire, so that it can be replaced or replaced if necessary. Furthermore, the inner lateral boundary 11 of the side member 1 is provided with counter-braking surfaces 12 which run essentially parallel to the brake pads 10 on the running wheels 8. These counter-braking surfaces 12 are also fastened replaceably if necessary.

Gebremst wird dadurch, daß entweder die Bremsbeläge 10 gegen die Bremsflächen 12 angepreßt werden oder die Bremsbeläge 10 der Laufräder 8 unmittelbar gegeneinandergepreßt werden, wobei natürlich die Achsen der beiden Laufräder 8 mehr oder weniger weit gegeneinander versetzt angeordnet sein müssen. Mit der Größe des Versatzes nimmt die Bremswirkung zu, so daß die Bremswirkung durch eine entsprechende Fußsteilung des Läufers genau dosierbar ist.It is braked in that either the brake pads 10 are pressed against the braking surfaces 12 or the brake pads 10 of the wheels 8 are pressed directly against each other, of course, the axes of the two wheels 8 must be arranged offset more or less far from each other. The braking effect increases with the size of the offset, so that the braking effect can be precisely metered by a corresponding foot division of the runner.
