Keramische Gleitkufen auf Eis; * "" "* Seite: 1/2Ceramic gliding blades on ice; * "" "* Page: 1/2
Beschreibung:Description:
Für Wintersportgeräte wie aber auch für Gegenstände des praktischen täglichen Gebrauchs ist nach bekannten physikalischen Grundlagen das Gleiten über Eis, Schnee - also gefrorenem Wasser in irgendeiner Form - mit diesem verhältnismäßig geringen Reibwiderstand nur deshalb möglich, weil unter der Last der Kufe die Eisoberfläche aufgrund der unterschiedlichen Dichte bei Wasser je nach hauptsächlich dem Druck und der Temperatur kurzfristig in flüssigen Zustand aufschmilzt und somit einen flüssigen Film zwischen den beiden festen Körpern - Kufe und Eis - als eine Art Schmierfilm bildet.For winter sports equipment as well as for objects of practical everyday use, according to known physical principles, gliding over ice, snow - i.e. frozen water in any form - with this relatively low frictional resistance is only possible because under the weight of the runner, the ice surface briefly melts into a liquid state due to the different density of water depending mainly on the pressure and temperature, thus forming a liquid film between the two solid bodies - runner and ice - as a kind of lubricating film.
Andere Faktoren wie z.B. Verunreinigung des gefrorenen Wassers oder Temperatur der Kufe und ähnliches verlagern diesen Vorgang nur in andere z.B. Temperaturbereiche, ändern jedoch grundsätzlich nichts an der hier zu schützenden Idee.Other factors such as contamination of the frozen water or temperature of the runner and the like only shift this process to other temperature ranges, but fundamentally do not change the idea to be protected here.
Bei der Reibung zwischen einem festen Körper und Eis unter Einflußnahme des Mediums Wasser handelt es sich um ein tribologisches System, bei dem hauptsächlich fünf Faktoren von Bedeutung sind: Reibungskoeffizient, entstehende Reibungswärme ,Wärmeleitf ähigkeit , Adhäsion zwischen Wasser und den festen Körpern, Benetzungsqualität der Oberflächen. Andere physikalische Größen wie z.B. Wärmeleitgeschwindigkeit, Oberflächenrauhigkeit und andere mehr hängen direkt oder indirekt mit den vorgenannten Größen physikalisch-mathematisch zusammen.The friction between a solid body and ice under the influence of water is a tribological system in which five main factors are important: coefficient of friction, frictional heat generated, thermal conductivity, adhesion between water and the solid bodies, wetting quality of the surfaces. Other physical quantities such as thermal conduction rate, surface roughness and others are directly or indirectly related to the aforementioned quantities in a physical and mathematical way.
Solche Gleitkufen für Sportgeräte aber auch praktische Fahrzeuge auf Eis haben bis jetzt üblicherweise Stahl, Hartmetalle und/oder Kunsstoffe als Gleitkufen. Sinn der hier zu schützenden Idee ist es, diese Gleitkufen nicht aus Metallen, Holz, Kunststoff oder ähnlichem sondern aus Keramik herzustellen mit dem Ziel, die Gleiteigenschaften zu verbessern.Such skids for sports equipment and also practical vehicles on ice have usually had steel, hard metals and/or plastics as skids. The idea to be protected here is to manufacture these skids not from metals, wood, plastic or similar but from ceramics with the aim of improving the sliding properties.
Als Keramiken in diesem Sinn werden Metallverbindungen gesehen, deren Molekül nur teilweise aus Metall besteht, z.B.: Aluminiumoxid, Siliziumnitrid, Zirkonoxid und viele andere mehr und deren Mischungen samt für das Brennen und/oder die spätere Verarbeitung notwendigen Zusätze. Diese Materialien werden durch Erhitzen unter bestimmten Bedingungen zu zusammenhängenden Körpern verbunden. Diese keramischen Körper können auch noch Einschlüsse wie Wisker, Glasfasern, Kohlestoffasern oder Gas/Luft (Poren) und ähnliches haben.Ceramics in this sense are metal compounds whose molecules only partially consist of metal, e.g. aluminum oxide, silicon nitride, zirconium oxide and many others and their mixtures including additives necessary for firing and/or subsequent processing. These materials are combined into coherent bodies by heating under certain conditions. These ceramic bodies can also have inclusions such as wisps, glass fibers, carbon fibers or gas/air (pores) and the like.

Keramische Gleitkufen auf Eis; "* Seite: 2/2Ceramic gliding blades on ice; "* Page: 2/2
Beschreibung:Description:
Keramiken bieten heute fast alle wünschenswerten technisch-physikalischen Eigenschaften, die auch für dieses Gleiten auf Eis von Vorteil sind. Die hier zu schützende Idee besteht darin, solche Gleitkufen aus Keramiken zu erstellen. Das trifft z.B. für Schlittschuhe, Schlitten, Skier und ähnliches zu.Today, ceramics offer almost all desirable technical and physical properties that are also beneficial for gliding on ice. The idea to be protected here is to make such runners out of ceramics. This applies, for example, to ice skates, sledges, skis and the like.
Damit wird erreicht, daß die Gleitkufe auf dem Eis insgesamt einen geringeren Reibungswiderstand hat als herkömmliche Metalle. Je nach äußeren Umständen - Temperatur, Sauberkeit des Eises, Zusätze im gefrorenen Wasser, künstliches oder natürliches Eis und anderes mehr - können hier unterschiedliche Keramiken nützlich sein. Zusätzlich kann es nötig sein, eine poröse Keramik zu verwenden und deren Hohlräume mit öl, anderen Flüssigkeiten oder ähnlichem zu tränken, um z.B. die Benetzungseigenschaften und/oder Adhäsionskräfte usw. positiv zu verändern.This means that the runner has a lower frictional resistance on the ice than conventional metals. Depending on the external circumstances - temperature, cleanliness of the ice, additives in the frozen water, artificial or natural ice and more - different ceramics can be useful here. In addition, it may be necessary to use a porous ceramic and to soak its cavities with oil, other liquids or similar in order to positively change the wetting properties and/or adhesion forces, etc.
Ferner wird bewirkt, daß diese keramischen Gleitkufen durch ihre wesentlich gegenüber Stahl verbesserte Errosionbestandigkeit eine längere Lebensdauer erhalten. Das gilt nicht nur für die Lebensdauer dieser Geräte sonder auch z. B. für die Dauer eines Schlittschuhlanglaufrennens.Furthermore, these ceramic runners have a longer service life due to their significantly improved erosion resistance compared to steel. This applies not only to the service life of these devices but also, for example, to the duration of a cross-country skating race.
Diese Erfindung bezieht sich auf die Gleitkufe selbst sowie auf ein Gerät, das eventuell vollständig aus Keramik besteht. Auch austauschbare oder anders entfernbare und/oder veränderbare Gleitkufen für alle Sorten von Schlittschuhen, Schlitten oder ähnlichem werden hiermit ausdrücklich erfasst. Auch Gleitkufen, die ganz oder teilweise durch Metallteile oder andere Körper/Gegenstände gestützt werden sowie Gleitkufen, die nur teilweise aus Keramik bestehen, während z. B. das Kopfstück und/oder das Ende aus anderen Materialien bestehen, sind Gegenstand dieser Erfindung.This invention relates to the skid itself and to a device that may be made entirely of ceramic. Also, replaceable or otherwise removable and/or changeable skids for all types of skates, sledges or the like are expressly covered hereby. Skids that are fully or partially supported by metal parts or other bodies/objects, as well as skids that are only partially made of ceramic, while, for example, the head piece and/or the end are made of other materials, are also the subject of this invention.
Ferner beinhaltet das auch, daß z.B. die Lauffläche von Skiern, Snowcars und ähnlichem oder deren Kanten ganz oder teilweise aus Keramik bestehen. So kann z. B. die Lauffläche von Langlaufskiern aus vielen Keramikkacheln bestehen, die beweglich zum Skie gelagert sind und somit in Laufrichtung einen möglich geringen Laufwiderstand bilden während in die entgegengesetzte Richtung also beim Antreiben - diese Keramikkacheln sich verstellen und Absätze bilden, die ein in diese Richtung ungewünschtes Gleiten erschweren.This also means that the running surface of skis, snow cars and similar or their edges are made entirely or partially of ceramic. For example, the running surface of cross-country skis can consist of many ceramic tiles that are mounted so that they can move relative to the ski and thus create as little running resistance as possible in the running direction, while in the opposite direction - i.e. when driving - these ceramic tiles adjust and form steps that make it difficult to slide in this direction.
