Abstract
Description
Sportgerät Die @rfindung betrifft ein Sportgerät aus einem Hartschaum mit aussen dichter und innen weniger verdichteter, poröser Struktur und mit glatten Aussenflächen. Es ist @adurch gekennzeichnet, dass es ein @ki ist. Sports equipment The invention concerns sports equipment made from rigid foam with a porous structure that is dense on the outside and less compacted on the inside, and with smooth Outside areas. It's @marked to be a @ki.
Schneeschuhe werden bisher aus Holz, Metall oder Schichteierkstoffen hergestellt. Sie sind für Kinder schwer und darüberhinaus teuer. Gegenüber dem Bekannten hat demnach der Lrfindungsgegenstand die Vorteile des geringen Preises und der Bequemlichkeit des kleinen Gewichts sowohl für die Kinder als auch Sür deron Eltern. Dios iut nach dem Bekanntgeb@n der Erfindungsidee leicht glaubhaft, doch war das Begehron der Verbraucher alt. Bs bedurfte des Ueberwindens eines Vorurteiles, um zum Erfindungsgegenstand hinzugelangen, zumal da es jedermann weiß, dass bei Schaumkörpern die spezifische Druckfestigkeit extrem klein ist.Up to now, snowshoes are made of wood, metal or laminated composites manufactured. They are heavy for children and also expensive. Compared to the known Accordingly, the subject of the invention has the advantages of low price and convenience of small weight for both the children and sureron parents. Dios iut after The announcement of the invention is easily credible, but the desire was the Consumer old. Bs needed to overcome a prejudice in order to become the subject of the invention especially since everyone knows that the specific foam bodies Compressive strength is extremely small.
Die Zeichnung zeigt zwei @nsprüche in Querschnitten.The drawing shows two statements in cross-sections.
Von diesen lot die Variante nach Fig 1 die Widerstandsfähigste weil deren Stemmkanten mit "Stahlkanten" 3, also mit Verstärkun ,sschienen bewehrt sind.Of these, the variant according to FIG. 1 is the most resistant because whose caulking edges are reinforced with "steel edges" 3, that is to say with reinforcement rails.
Der Ski selber besteht aus einem an sich bekannten Hartschaum mit einem stark porösen Kern, so dass die Dichte des Werkstoffes nach auswärts zunimmt. Die Aussenflächen sind glatt und porenlos, so dass vor allen die Gleitflache eine gate Rutscheigenschaft hat.The ski itself consists of a hard foam known per se a strongly porous core, so that the density of the material increases towards the outside. The outer surfaces are smooth and pore-free, so that above all the sliding surface is a gate has slide properties.
Beim Ausführungsbeispiel nach Fig 2 ist die Bindungsplatte 2 ein von Hart schaum getragenes Druckstück, so dass Ankerstifte 2a eines Ankers z.B. einer Ankerplatte 3 die Bindungsplatte und die Hartschaumumbettung durchdringen, die an sich bekannte Bindungsplatte aber die zusätzliche Bunktion ausübt, das Kindergewicht auf eine grosse Fläche des relativ weichen Hartschaumkörpers zu verteilen.In the embodiment of FIG. 2, the binding plate 2 is one of Pressure piece carried by hard foam, so that anchor pins 2a of an anchor, e.g. a Anchor plate 3 penetrate the binding plate and the rigid foam bedding that is attached to known binding plate but has the additional function of child weight To be distributed over a large area of the relatively soft rigid foam body.
Bei beiden Varianten sind noch Kantenstreifen aus einem hochelastischen Thermoplast vorgesehen, um einerseits ßiegezugspannungen aufzufangen und andererseits die Rutscliqualität des Schneeschuhes hochzuhalten.In both variants there are also edge strips made of a highly elastic one Thermoplastic provided to absorb bending tensile stresses on the one hand and on the other hand to keep the slip quality of the snowshoe high.
