SPORTGERÄTSPORTS EQUIPMENT
Technisches GebietTechnical field
Die vorliegende Erfindung betrifft ein Sportgerät mit einem länglichen, plattenförmigen Grundkörper nach dem Oberbe¬ griff des Anspruchs 1.The present invention relates to a sports device with an elongated, plate-shaped base body according to the preamble of claim 1.
Stand der TechnikState of the art
Der gattungsbildende Stand der Technik ergibt sich aus der DE 27 11 930 AI. In Fig. 7 dieser Druckschrift ist eine Vorrichtung zum Gleiten auf Schnee gezeigt, an deren Unter¬ seite im mittleren Bereich ein System von Führungen vorgesehen ist, das zwei äußere Führungen 10, zwei innere Führungen 9 zwischen den äußeren Führungen 10 und eine mittlere Führung 8 umfaßt, die auch kürzer oder länger sein kann als es in Fig. 7 gezeigt ist. Die Führungen 9 sind symmetrisch zur Führung 8 angeordnet und schwach gewölbt, wobei die Wölbung im hinteren Bereich stärker ist. Die äußere Führung 10 ist noch stärker gewölbt als die Führung 9 (siehe Beschreibung, Seite 24, dritter und vierter Absatz). Daraus folgt, daß der Abstand zwischen den Führungen 9 und 10 nach hinten hin zunimmt. Über die Höhe der Führungen der Ausführungsform von Fig. 7 der DE 27 11 930 AI ist keine Aussage getroffen.The generic state of the art results from DE 27 11 930 AI. 7 of this document shows a device for sliding on snow, on the underside of which a system of guides is provided in the central region, which has two outer guides 10, two inner guides 9 between the outer guides 10 and a central guide 8 which may be shorter or longer than that shown in FIG. 7. The guides 9 are arranged symmetrically to the guide 8 and are slightly curved, the curvature being stronger in the rear area. The outer guide 10 is curved even more than the guide 9 (see description, page 24, third and fourth paragraph). It follows that the distance between the guides 9 and 10 increases towards the rear. No statement is made about the height of the guides of the embodiment of FIG. 7 of DE 27 11 930 AI.
Da die Führungen der in Fig. 7 gezeigten Ausführungsform im wesentlichen gleich lang sind, bilden die Führungen Kraft¬ linien, die im wesentlichen parallel zur Längsachse verlaufen. Ein Richtungswechsel kann nur durch volle Gewichtsverlagerung von mindestens 50% auf eine der parallelen Kraftlinien voll¬ zogen werden. Dadurch wird eine Veränderung der Fußstellung notwendig, die zwangsläufig zu einem labilen Schwerpunkt des Fahrers führt. Wenn die Führungen 8, 9, 10 auf gleicher Höhe angeordnet sind, wird die Steuerwirkung der einzelnen Führun¬ gen gegenseitig aufgehoben. Dies kann nur durch große Höhen¬ unterschiede vermieden werden, wie es beispielsweise in den Fig. 9 bis 12 der DE 27 11 930 AI gezeigt ist. Eine derartige Maßnahme führt jedoch zu erhöhten Neigungswinkeln und damit zu einer Instabilität des Fahrers bei Richtungswechsel.Since the guides of the embodiment shown in FIG. 7 are of substantially the same length, the guides form lines of force which run essentially parallel to the longitudinal axis. A change of direction can only be accomplished by a full weight shift of at least 50% to one of the parallel lines of force. This makes it necessary to change the foot position, which inevitably leads to an unstable center of gravity for the driver. If the guides 8, 9, 10 are arranged at the same height, the control effect of the individual guides is mutually canceled. This can only be avoided by large differences in height, as is the case, for example, in FIGS 9 to 12 of DE 27 11 930 AI is shown. However, such a measure leads to increased inclination angles and thus to driver instability when changing direction.

Das Sportgerät weist einen im wesentlichen ovalen, plat¬ tenförmigen Grundkörper 10 auf, der eine Oberseite 11 und eine Unterseite 12 besitzt.The sports device has an essentially oval, plate-shaped base body 10, which has an upper side 11 and a lower side 12.
Der Grundkörper 10 steigt im vorderen Drittel in einem Winkel von ungefähr 10° an und bildet einen gleichmäßig leicht gewölbten Verlauf zum auslaufenden vorderen Teil. Die hinteren zwei Drittel Kufenauflage laufen vor der hinteren Steigung im Verlauf zur Horizontalen des Grundkörpers 10 plan aus und bilden einen fließenden Übergang in die hintere Steigung. Der vordere Bereich 13, der ungefähr 1/6 bis 1/10 der Gesamt¬ länge des Grundkörpers 10 einnehmen kann, und der hintere Bereich 14, der ungefähr 1/5 bis 1/7 der Gesamtlänge des Grundkörpers 10 einnehmen kann, sind jeweils zur Horizontalen nach oben geneigt. Der Winkel zwischen dem vorderen Bereich 13 und der Horizontalen beträgt ungefähr zwischen 10" und 20", beispielsweise ungefähr 15°. Der Winkel zwischen dem hinteren Bereich 14 und der Horizontalen beträgt ungefähr zwischen 15° und 25", beispielsweise ungefähr 20".The base body 10 rises in the front third at an angle of approximately 10 ° and forms a uniformly slightly curved course to the front part that runs out. The rear two thirds of the runner run flat in front of the rear slope in the course of the horizontal of the base body 10 and form a smooth transition to the rear slope. The front area 13, which can take up about 1/6 to 1/10 of the total length of the base body 10, and the rear area 14, which can take up about 1/5 to 1/7 of the total length of the base body 10, are each for Horizontal inclined upwards. The angle between the front region 13 and the horizontal is approximately between 10 "and 20", for example approximately 15 °. The angle between the rear area 14 and the horizontal is approximately between 15 ° and 25 ", for example approximately 20".
Die Biegung des vorderen Bereichs 13 bewirkt eine bessere Standfestigkeit des Anwenders, ein besseres Gleitverhalten des Sportgeräts und verhindert, daß dieses z.B. unter die Schnee¬ linie abtauchen kann.The bend of the front area 13 results in better stability of the user, better sliding behavior of the sports equipment and prevents it from e.g. can dive under the snow line.
Die Biegung des hinteren Bereichs 14 bewirkt eine bessere Standfestigkeit des Anwenders und eine Verbesserung der Ma¬ növrier- und Bremsfähigkeit des Sportgeräts. Die Bremswirkung wird in der Regel mit einer mehr oder weniger leichten Drehung des Sportgeräts erreicht.The bending of the rear area 14 brings about a better stability of the user and an improvement of the maneuverability and braking ability of the sports device. The braking effect is usually achieved with a more or less slight rotation of the sports equipment.
Die Unterseite des hinteren Bereichs 14 des Sportgeräts kann zusätzlich mit ein bis drei, beispielsweise im Grundriss dreieckigen, mit einer Spitze jeweils in Längsrichtung nach vorne ausgerichteten, sich zur Auflagefläche hin verjüngenden Bremskeilen 21 ausgestattet werden.The underside of the rear area 14 of the sports device can additionally be equipped with one to three brake wedges 21, for example triangular in plan, each with a point oriented forwards in the longitudinal direction and tapering towards the bearing surface.
Die hinteren Bremskeile 21 liegen aufgrund der Steigung des hinteren Bereichs 14 tiefer, damit das Sportgerät beim Bremsen nicht zu stark abgesenkt werden muß. Das Sportgerät kann auch mit mehreren kleineren oder größeren als den in Fig.l und Fig.2 dargestellten Bremskeilen ausgestattet sein.The rear brake wedges 21 are lower due to the slope of the rear area 14, so that the sports equipment does not have to be lowered too much when braking. The sports device can also be equipped with several smaller or larger brake wedges as shown in Fig.l and Fig.2.
Als Bremsträger kann auch anstelle von Bremskeilen 21 ein entsprechendes Rippen- oder Noppenprofil an der Unterseite des hinteren Bereichs 14 dienen.A corresponding rib or nub profile on the underside of the rear region 14 can also serve as the brake carrier instead of the brake wedges 21.
Um ein Abrutschen des Anwenders vom Sportgerät zu ver¬ meiden kann die als Fußauflägefläche dienende Oberseite des vorderen Bereichs 13, des hinteren Bereichs 14 und des mitt¬ leren Bereichs 15 mit Anti-Rutsch-Streifen ausgestattet wer¬ den.In order to prevent the user from slipping off the sports equipment, the top of the front area 13, the rear area 14 and the central area 15, which serves as the footrest surface, can be equipped with anti-slip strips.
Das Verhältnis von Länge, bezogen auf die Längsmittel¬ linie, zu Breite und Höhe, jeweils bezogen auf den Mittelpunkt des Grundkörpers 10, beträgt bei dem Sportgerät zwischen 13:4:1 und 10:7:1, und beispielsweise ungefähr 11,5:5,5:1.The ratio of length, based on the longitudinal center line, to width and height, in each case based on the center of the base body 10, is between 13: 4: 1 and 10: 7: 1 in the sports device, and for example approximately 11.5: 5.5: 1.
Auf dem mittleren Bereich 15 der Unterseite des Grundkör¬ pers 10 sind zwei äußere Kufen 16 und zwei innere Kufen 17 angeordnet, die sich im wesentlichen in Längsrichtung er¬ strecken.Two outer runners 16 and two inner runners 17 are arranged on the central region 15 of the underside of the base body 10 and extend essentially in the longitudinal direction.
Die äußeren Kufen 16 sind breit und als Stütz- und Trage¬ kufen konzipiert. Die inneren Kufen 17 sind schlanker und länger als die äußeren Kufen 16 und als Gleit- und Steuerkufen konzipiert. Die inneren Kufen 17 verlaufen nach hinten bis zum Winkelansatz der Steigung plan.The outer runners 16 are wide and designed as supporting and carrying runners. The inner skids 17 are slimmer and longer than the outer skids 16 and designed as sliding and control skids. The inner runners 17 run flat back to the angle of the slope.
Die jeweilige innere Seitenfläche der äußeren Kufen 16 ist konvex ausgebildet. Die jeweilige äußere Seitenfläche der inneren Kufen 17 ist konkav ausgebildet. Die jeweilige innere Seitenfläche der inneren Kufen 17 ist konvex ausgebildet.The respective inner side surface of the outer runners 16 is convex. The respective outer side surface of the inner runners 17 is concave. The respective inner side surface of the inner runners 17 is convex.
Das Verhältnis der Breite jeweils einer äußeren Kufe 16 zu der Breite jeweils einer inneren Kufe 17 liegt in Höhe des Mittelpunkts im Bereich von ungefähr 3:1 bis 2:1, beispiels¬ weise bei 2,5:1.The ratio of the width of each outer runner 16 to the width of each inner runner 17 at the center is in the range from approximately 3: 1 to 2: 1, for example 2.5: 1.
Der Abstand der Stirnflächen der äußeren Kufen 16 von der Bodenfläche der zwischen der jeweiligen konvexen Seitenfläche der äußeren Kufe 16 und der ihr zugewandten konkaven Seiten¬ fläche der inneren Kufe 17 befindlichen Nut 19 beträgt, in Abhängigkeit von der Größe des Grundkörpers 10, zwischen 2,5 und 4 cm, beispielsweise 3 cm.The distance of the end faces of the outer runners 16 from the bottom surface of the groove 19 located between the respective convex side face of the outer runners 16 and the concave side face of the inner runners 17 facing them is, depending on the size of the base body 10, between 2, 5 and 4 cm, for example 3 cm.
Der Abstand der Stirnflächen der inneren Kufen 17 von der Bodenfläche der zwischen der jeweiligen konvexen Seitenfläche der äußeren Kufe 16 und der ihr zugewandten konkaven Seiten¬ fläche der inneren Kufe 17 befindlichen Nut 19 liegt im Be¬ reich von 3 bis 4,5 cm und beträgt beispielsweise 3,5 cm.The distance between the end faces of the inner runners 17 from the bottom surface of the groove 19 located between the respective convex side surface of the outer runners 16 and the concave side surface of the inner runners 17 facing them is in the range of 3 to 4.5 cm and is for example 3.5 cm.
Die inneren Kufen 17 sind höher als die äußeren Kufen 16. Die Höhendifferenz der jeweiligen Stirnflächen beträgt zwi¬ schen 3 und 8, beispielsweise 5 mm. Die inneren Kufen 17 sind jeweils in die Richtung des entsprechenden Längsrandes konkav gekrümmt, wobei die Krümmung in Längsrichtung im vorderen Ver¬ lauf schwächer ist als im hinteren Verlauf. Dadurch wird es ermöglicht, durch Gewichtsverlagerung das Sportgerät in die gewünschte Richtung zu steuern.The inner runners 17 are higher than the outer runners 16. The height difference of the respective end faces is between 3 and 8, for example 5 mm. The inner runners 17 are each concavely curved in the direction of the corresponding longitudinal edge, the curvature in the longitudinal direction being weaker in the front course than in the rear course. This makes it possible to steer the sports equipment in the desired direction by shifting weight.
Die Bodenfläche der zwischen den inneren Kufen 17 befind¬ lichen Aussparung 20 kann höher sein als die Bodenfläche der Nut 19. Die Höhendifferenz beträgt dann, in Abhängigkeit von der Dicke des Grundkörpers 10, zwischen 3 und 8 mm, beispiels¬ weise 5 mm.The bottom surface of the recess 20 located between the inner runners 17 can be higher than the bottom surface of the groove 19. The height difference is then, depending on the thickness of the base body 10, between 3 and 8 mm, for example 5 mm.
Auf der Längsmittellinie ab ungefähr dem Mittelpunkt des Sportgeräts bis ungefähr zum hinteren Ende der inneren Kufen 17 befindet sich eine Stabilisierungskufe 18, die an ihrer höchsten und breitesten Stelle höher als die inneren Kufen 17 ist. Die Höhendifferenz der jeweiligen Stirnflächen beträgt zwischen 3 und 8 mm, beispielsweise 5 mm.On the longitudinal center line from approximately the center of the sports device to approximately the rear end of the inner skids 17 there is a stabilizing skid 18, which is higher than the inner skids 17 at its highest and widest point. The height difference of the respective end faces is between 3 and 8 mm, for example 5 mm.
Die Stabilisierungskufe 18 läuft in Längsrichtung nach vorne spitz zu und nach hinten breit aus. Die Stirnfläche der Stabilisierungskufe 18 läuft plan von der Mitte des Grundkör¬ pers 10 nach hinten aus und ist im Grundriss tropfenförmig.The stabilizing skid 18 tapers to the front in the longitudinal direction and broadly to the rear. The end face of the stabilizing skid 18 runs flat from the center of the base body 10 to the rear and is drop-shaped in plan.
Die Kufen 16, 17 und 18 laufen in Längsrichtung nach vorne und nach hinten flach aus. Die inneren Kufen 17 können bis ungefähr zur Mitte der vorderen Steigung auslaufen.The runners 16, 17 and 18 run flat in the longitudinal direction to the front and to the rear. The inner runners 17 can run out to approximately the middle of the front slope.
Das Sportgerät kann im vorderen Bereich zur Befestigung einer Zugleine eine Bohrung aufweisen.The sports device can have a hole in the front area for attaching a pull line.
Durch den vorgehend beschriebenen Aufbau der Unterseite 12 ergeben sich die folgenden Manövriermöglichkeiten des Sportgeräts: 1. Das Gewicht des Anwenders ist gleichmäßig auf den vorderen und den hinteren Bereich des Sportgeräts verteilt: a) Durch Verlagerung des Gewichtes auf die linke Seite führt das Sportgerät eine sanfte Linkskurve aus. b) Durch Verlagerung des Gewichtes auf die rechte Seite führt das Sportgerät eine sanfte Rechtskurve aus.The above-described construction of the underside 12 results in the following maneuvering possibilities for the sports device: 1. The weight of the user is evenly distributed over the front and rear area of the sports equipment: a) By shifting the weight to the left side, the sports equipment performs a gentle left turn. b) By shifting the weight to the right side, the sports equipment makes a gentle right turn.
2. Das Gewicht des Anwenders liegt zum größten Teil auf dem hinteren Bereich: a) Durch Verlagerung des Gewichtes auf die linke Seite führt das Sportgerät eine stärkere Linkskurve aus. b) Durch Verlagerung des Gewichtes auf die rechte Seite führt das Sportgerät eine stärkere Rechtskurve aus. c) Ein Zentrieren des Gewichts auf der Stabilisierungskufe 18, ermöglicht das Erreichen von größeren Geschwindigkeiten, sowie das Fahren in tieferem Schnee und die schnelle und wendige Durchführung der unter 2a) und 2b) beschriebenen Manöver.2. The weight of the user is mostly on the rear area: a) By shifting the weight to the left side, the sports equipment performs a stronger left turn. b) By shifting the weight to the right side, the sports equipment makes a stronger right turn. c) Centering the weight on the stabilizing skid 18 enables higher speeds to be reached, as well as driving in deeper snow and quick and agile execution of the maneuvers described under 2a) and 2b).
Durch diese stark ausgeprägten Manövrierfähigkeiten und dadurch, daß das Sportgerät in der Regel nicht größer als ein herkömmlicher Rodelschlitten und gemäß einer Ausführungsform leicht ist, wird die Verletzungsgefahr sowohl für den Anwender als auch für andere Personen z.B. im Vergleich zu anderen Wintersportgeräten, wie Schlitten, Plastikbobs, Snowboards oder Ski, erheblich gemindert.Due to these strong maneuverability and the fact that the sports equipment is usually no larger than a conventional toboggan and is lightweight according to one embodiment, the risk of injury to both the user and other people is e.g. significantly reduced compared to other winter sports equipment such as sledges, plastic bobs, snowboards or skis.
Die Manövrierfähigkeit des Sportgeräts entspricht der eines Skateboards. Damit bietet dieses Sportgerät ideale Ergänzungsmöglichkeiten im Winter zum Skateboardfahren im Sommer, da eine Umgewöhnung nicht erforderlich ist.The maneuverability of the sports equipment corresponds to that of a skateboard. This sports device thus offers ideal complementary options in winter for skateboarding in summer, since it is not necessary to get used to it.
Der Grundkörper 10 des Sportgeräts kann aus einem hitze¬ härtbaren Kunststoff, z.B. einem Epoxidharz, das zusätzlich mit Glasfasern verstärkt sein kann, oder einem Methacrylat- oder Polyesterharz gegossen bzw. aus entsprechenden Formteilen zusammengesetzt sein. Der Grundkörper 10 des Sportgeräts kann auch aus Polyethylen hoher Dichte bestehen.The base body 10 of the sports device can be made of a thermosetting plastic, e.g. an epoxy resin, which can also be reinforced with glass fibers, or a methacrylate or polyester resin cast or composed of appropriate moldings. The base body 10 of the sports device can also consist of high-density polyethylene.
Der Grundkörper 10 des Sportgeräts kann auch aus einem Kern aus einem Hartschaumstoff, z.B. Polyurethan- oder Poly¬ styrol-Hartschaumstoff, und einer Umhüllung aus einem hitze¬ härtbaren Kunststoff, z.B. einem Epoxidharz, das zusätzlich mit Glasfasern verstärkt sein kann, oder einem Methacrylat- oder Polyesterharz bestehen.The base body 10 of the sports device can also consist of a core made of a rigid foam, for example polyurethane or polystyrene rigid foam, and a covering made of a thermosetting plastic, for example an epoxy resin, which additionally can be reinforced with glass fibers, or consist of a methacrylate or polyester resin.
In einer Ausführungsform besteht der Kern des Grundkör¬ pers 10 aus Polyurethan-Hartschaumstoff und einer Umhüllung aus Epoxidharz, das mit Glasfasern verstärkt ist. In one embodiment, the core of the base body 10 consists of rigid polyurethane foam and a covering made of epoxy resin, which is reinforced with glass fibers.
