Bisher werden Sport- und Spielreifen (sog. Hula-Hoop-Reifen) aus Holz oder aus Plaste hergestellt. Aus der Verwendung dieser Materialien resultieren jedoch eine ganze Reihe negativer Eigenschaften. Reifen aus Holz herzustellen ist schwierig und aufwendig. Weiterhin ist Holz feuchtigkeitsanfällig, was leicht zu Formveränderungen führen kann. Des weiteren wird der Reifen schon bei relativ geringen mechanischen Einwirkungen zerstört. Zwar läßt sich Plaste leichter verarbeiten, jedoch ist die spätere Formstabilität sowie die mechanische und thermische Festigkeit ebenfalls nur gering. Des weiteren stellt die Fertigung große Ansprüche an die Nachbearbeitung zur Beseitigung der Spritzgrate. Diese Grate können leicht zu Verletzungen führen.Up to now, sports and play hoops (so-called hula hoops) have been made from wood or plastic. However, the use of these materials results in a whole range of negative properties. Making hoops from wood is difficult and time-consuming. Furthermore, wood is susceptible to moisture, which can easily lead to changes in shape. Furthermore, the hoop is destroyed by even relatively minor mechanical impacts. Although plastic is easier to process, its subsequent dimensional stability and mechanical and thermal strength are also low. Furthermore, production places great demands on post-processing to remove injection burrs. These burrs can easily lead to injuries.
Ziel der Erfindung war es einen Sport- und Spielreifen zu entwickeln, welcher diese Herstellungs- und Benutzungsprobleme minimiert.The aim of the invention was to develop a sports and play tire that minimizes these manufacturing and usage problems.
Dies wurde gelöst, in dem zur Herstellung des Reifens Metall- oder Leichtmetallrohre wie z. B. AlU oder Titan verwandt wurden.This was solved by using metal or light metal tubes such as AlU or titanium to manufacture the tire.
Der Vorteil dieser Materialien liegt darin, daß schon bei der Produktion nur in geringem Maße in zusätzlichen Arbeitsgängen zu entfernende Grate entstehen, was die potentielle Verletzungsgefahr minimiert. Des weiteren kann mittels der Materialwahl die Masse des Reifens bei gleichen äußeren Abmessungen in einem großen Bereich frei gewählt werden, so daß unterschiedliche Trägheiten erreichbar sind. Des weiteren sind diese Reifen rotationsstabiler, da aufgrund der Verwendung von Metallrohren nur geringste Unwuchten entstehen.The advantage of these materials is that only a small amount of burrs are created during production that need to be removed in additional operations, which minimizes the potential risk of injury. Furthermore, the choice of material allows the mass of the tire to be freely selected within a wide range while maintaining the same external dimensions, so that different inertias can be achieved. Furthermore, these tires are more rotationally stable because the use of metal tubes means that only minimal imbalances occur.

Durch die Auswahl entsprechenden Rohrmaterials oder Oberflächenvergütung ist der Reifen auch korrosionsresistent, d. h. wasserunempfindlich und die Oberflächenglätte bleibt auch bei mechanischen Einwirkungen erhalten. Insgesamt ist der Reifen nach dieser Erfindung langfristig unempfindlicher gegenüber mechanischen oder thermischen Einwirkungen als solche aus Plaste oder Holz.By selecting the appropriate tube material or surface treatment, the tire is also corrosion-resistant, i.e. insensitive to water, and the surface smoothness is retained even when subjected to mechanical influences. Overall, the tire made according to this invention is less sensitive to mechanical or thermal influences in the long term than those made of plastic or wood.
Der Reifen besteht aus einem, entsprechend der erwünschten Abmessung, unter Vorspannung gebogenen Rohr. Dies wird mittels eines Bolzens (1), welcher über drei Abschnitte mit zwei unterschiedlichen Durchmessern verfügt zu einem Ring (2) verschlossen.The tire consists of a tube bent under pre-tension according to the desired dimensions. This is closed to form a ring (2) using a bolt (1) which has three sections with two different diameters.
Der Durchmesser des mittleren Abschnittes des Bolzens entspricht dem Außendurchmesser des Rohres. Die beiden äußeren Abschnitte werden mit einem geringfügig kleineren Durchmesser als der Innendurchmesser des Rohres ausgeführt.The diameter of the middle section of the bolt corresponds to the outside diameter of the pipe. The two outer sections are made with a slightly smaller diameter than the inside diameter of the pipe.
Der Bolzen wird beim Verschließen mit dem Ring zusätzlich verklebt.The bolt is additionally glued to the ring when closed.
