Problemproblem
Der in den Schutzansprüchen 1 bis 9 angegebenen Erfindung liegt das Problem zugrunde, dass bekannten Kernkonstruktionen eine gewisse Mindestdicke und Mindestgewicht aufweisen und immer in Verbindung mit entsprechenden Zug- und Druckelementen, bestehend aus verschiedensten, künstlichen Laminaten wie beispielsweise GFK oder Karbon aufgebaut sind, um den hohen physikalischen Anforderungen, welche an Snowboards oder Ski aller Art gestellt werden standzuhalten. Erst durch den Einsatz relativ großer Mengen an Laminaten und Klebstoffen wird die gewünschte Festigkeit und Dauerelastizität der Konstruktion erreicht. Der eigentliche Kern übernimmt in diesen Fällen primär die Aufgabe den Raum zwischen den Laminaten zu füllen und hat kaum mehr die Eigenschaft Zug- Druck und Torsionskräfte zu übernehmen. Des weiteren weisen herkömmliche Konstruktionen ein sehr technisches und widernatürliches Fahr- und Flexverhalten auf.The in the protection claims 1 to 9 specified invention is based on the problem that known Core constructions a certain minimum thickness and minimum weight have and always in connection with appropriate tension and pressure elements, consisting of various, artificial Laminates such as GRP or carbon are built around the high physical requirements that snowboards or All types of skis are made to withstand. Only through the effort relatively large Amounts of laminates and adhesives will give the construction the desired strength and permanent elasticity reached. The actual core takes over in these cases primary the task of filling the space between the laminates and hardly has that anymore Property of taking over tensile, compressive and torsional forces. Furthermore point conventional Constructions a very technical and unnatural driving and flex behavior on.
Lösungsolution
Diese Probleme werden mit den in Schutzanspruch 1 bis 9 angegebenen Merkmalen gelöst.This Problems are with the features specified in claims 1 to 9 solved.
Erreichte VorteileAchieved advantages
Mit der Erfindung wird erreicht, dass die Konstruktion für Snowboards oder Ski aller Art mit einem leichten, in sich biege- und verwindungssteifen Bambuskernaufbau, bei dem nur noch ein geringer Anteil an Klebstoffen zum Einsatz kommt und der Hauptanteil der Konstruktion aus schnell nachwachsenden, recyclebaren Rohstoffen besteht. Weiterhin kann auf die üblichen Laminate idealerweise vollends verzichtet werden, da zug-, druck- und Torsionskräfte von den in Längsrichtung ungestoßenen, hochbelastbaren Bambusfurnieren übernommen wird. Darüber hinaus weist die Bambuskonstruktion gegenüber herkömmlichen Konstruktionen ein sehr natürliches Fahr- und Flexverhalten bei der Benutzung des Snowboard oder der Ski aller Art auf.With The invention achieves that the construction for snowboards or skis of all kinds with a light, inherently rigid and torsionally rigid Bamboo core structure, in which only a small proportion of adhesives is used and the main part of the construction from fast renewable, recyclable raw materials. Furthermore can to the usual Ideally, laminates should be completely dispensed with, since tensile, compressive and torsional forces of those in the longitudinal direction ungestoßenen, heavy-duty bamboo veneers becomes. About that In addition, the bamboo construction shows compared to conventional constructions very natural driving and flex behavior when using the snowboard or the skis of everyone Kind of.
