Description
Ski ski
Die Erfindung bezieht sich auf einen Ski, bei dem auf einen Rohski, vorzugsweise bestehend aus Gurtschichten, Kern, Laufsohle und gegebenenfalls Stahlkanten, an seiner Oberseite und seinen Seitenflächen eine Hülle aus vorzugsweise elasto erem Kunststoff aufgeformt ist.The invention relates to a ski in which a shell of preferably elasto eres plastic is molded onto a raw ski, preferably consisting of belt layers, core, outsole and optionally steel edges, on its top and its side surfaces.
Eine solche Bauweise für Skier ist bekannt, wobei üblicher- weise die Hülle einstückig auf den Rohski aufgeformt wird, und zwar in einer Form, in die der Rohski eingelegt wird, worauf nach dem Schließen der Form das Material der Hülle unter Druck in den verbleibenden, der Hülle entsprechenden Formhohlräum eingeführt wird. Eine bevorzugte Ausgestaltung dieses Verfahrens ist das RIM (Reaction Injection Moulding)- Verfahren, durch welches Polyurethan bzw. dessen Komponenten Isocyanat und Polyol, die im Spritzkopf miteinander und mit einem Farbstoff vermengt werden, in den Formhohlraum ge¬ spritzt werden. Es wird meist mit Drücken (im Formhohlraum) von 2 bis 15 bar gearbeitet. Soll das Ergebnis - wie bevor¬ zugt, eine elastomere Polyurethan-Hülle sein, kann dies durch Auswahl und Einstellung der Komponenten des Polyurethans erreicht werden.Such a construction for skis is known, the casing being usually molded in one piece onto the raw ski, in a form in which the raw ski is inserted, after which, after the mold has been closed, the material of the casing under pressure in the remaining, the shell corresponding cavity is introduced. A preferred embodiment of this process is the RIM (Reaction Injection Molding) process, by means of which polyurethane or its components, isocyanate and polyol, which are mixed with one another and with a dye in the spray head, are injected into the mold cavity. Usually pressures (in the mold cavity) of 2 to 15 bar are used. If, as is preferred, the result is to be an elastomeric polyurethane shell, this can be achieved by selecting and adjusting the components of the polyurethane.
Aufgabe der Erfindung ist es, Skier der eingangs genanntenThe object of the invention is to ski the aforementioned
Bauweise zu verbessern, und zwar insbesondere in Hinblick auf eine gute Verbindung der Hülle mit dem Kern und auf eine gute Übertragung der Dämpfungswirkung (Torsions- und Biege¬ dämpfung) von der Hülle auf den Kern.To improve construction, in particular with regard to a good connection of the shell to the core and a good transmission of the damping effect (torsion and bending damping) from the shell to the core.
Dies wird erfindungsgemäß dadurch erreicht, daß mindestens Teile des Kernes aus Schaumstoffmaterial bestehen, das wenigstens in der der Hülle zugewandten Randzone porös ist, und daß das Kunststoffmaterial der Hülle das Schaumstoff- material des Kernes bzw. einzelner Kernteile zumindest in der Hülle zugewandten Randzonen des Kernes bzw. der Kernteile durchdringt.
Durch das Eindringen des Kunstεtoffmaterials der Hülle in die Randzonen des Schaumstoffmaterials des Kernes wird neben der Wirkung der adhäsiven und chemischen Haftkräfte, wobei die Porosität eine oberflächenvergrößernde und damit haftver- stärkende Wirkung ausübt, insbesondere auch eine Verklamme¬ rung von Hüllenmaterial und Schaumstoff im Kern erzielt. Dabei kommt es zur angestrebten verbesserten Verbindung zwischen Hülle und Kern und zur guten Übertragung der Dämpfungswirkung der Hülle auf den Kern. Außerdem kommt es zu einer Anhäufung des Materials der Hülle im Kern, und zwar am stärksten im mittleren Bereich des Skis, wo die Bauhöhe es Skis am größten ist.This is achieved according to the invention in that at least parts of the core consist of foam material which is porous at least in the edge zone facing the shell, and in that the plastic material of the shell the foam material of the core or individual core parts at least in the shell facing edge zones of the core or penetrates the core parts. As a result of the penetration of the plastic material of the shell into the edge zones of the foam material of the core, in addition to the effect of the adhesive and chemical adhesive forces, the porosity exerting a surface-enlarging and thus strengthening effect, in particular also a clinging of the shell material and foam in the core . This leads to the desired improved connection between the shell and the core and good transmission of the damping effect of the shell to the core. In addition, there is an accumulation of the material of the shell in the core, most particularly in the middle area of the ski, where the overall height of the skis is greatest.
Das Schaumstoffmaterial des Kerns kann vorzugsweise aus einem Polyurethan Schaum-Glasfaser-Verbundwerkstoff von isotropem Aufbau und mindestens in den Randzonen poröser Struktur bestehen. Der Glasfaseranteil kann aus einem Glasvlies, z.B. mit einem Flächengewicht von ca. 200 g/m gebildet sein. An¬ stelle von Glasfasern kann aber auch ein anderes Verstär- kungsmaterial verwendet werden. Auch der Einsatz von unver¬ stärkten, mindestens teilweise porösen Schaumstoffen ist denkbar.The foam material of the core can preferably consist of a polyurethane foam-glass fiber composite material with an isotropic structure and a porous structure at least in the edge zones. The glass fiber portion can be made from a glass fleece, e.g. be formed with a basis weight of approx. 200 g / m. Instead of glass fibers, another reinforcing material can also be used. The use of unreinforced, at least partially porous foams is also conceivable.
Das mindestens teilweise poröse Schaumstoffmaterial kann vor- zugsweise eine offenzellige oder eine gemischtzellige Zellen- Struktur aufweisen bzw. auf irgendeine andere Weise porös, d.h. für das (flüssige) Kunststoffmaterial der Hülle mehr oder weniger durchlässig sein.The at least partially porous foam material may preferably have an open-cell or a mixed-cell structure or in some other way porous, i.e. be more or less permeable to the (liquid) plastic material of the shell.
Es besteht die Möglichkeit, den ganzen Kern aus mindestens teilweise porösem, gegebenenfalls vertärktem Schaumstoff her¬ zustellen oder nur Teile des Kernes, insbesondere gesonderte Seitenteile.It is possible to manufacture the entire core from at least partially porous, possibly reinforced foam or only parts of the core, in particular separate side parts.
Die Hülle besteht vorzugsweise aus einem elastomeren Kunst¬ stoff, z.B. Polyurethan, wobei der Kunststoff der Hülle vor¬ zugsweise gemäß dem eingangs erwähnten RIM-Verfahren auf den Rohski aufgeformt wird.
Die Erfindung wird nachstehend anhand der Zeichnung durch Ausführungsbeispiele näher erläutert.The casing preferably consists of an elastomeric plastic, for example polyurethane, the plastic of the casing being molded onto the raw ski preferably according to the RIM process mentioned at the beginning. The invention is explained in more detail below with the aid of exemplary embodiments.
Fig. 1 zeigt die eine Hälfte eines Skiquerschnitts eines Alpinskis, Fig. 2 zeigt die eine Hälfte eines Skiquerschnitts z.B. eines Langlaufskis.Fig. 1 shows one half of a ski cross section of an alpine ski, Fig. 2 shows one half of a ski cross section e.g. a cross-country ski.
Der im Querschnitt dargestellte Ski besteht aus dem Obergurt 1 aus Leichtmetall, dem Untergurt mit einer Leichtmetall- schicht 2 und einer zusätzlichen Gurtschicht 2 ' aus Glas¬ faserlaminat, dem Kern mit einem Mittelteil 3 aus Holz und Seitenteilen 3' aus mindestens in der der Hülle 6 zugewandten Randzone porösem Schaumstoff, z.B. aus Polyurethan Glasfaser- Verbund-Schaumstoff, vorzugsweise mit einer Dichte von ca. 0,1 bis ca.0,3 bzw. 0,5 g/cm3. Stahlkanten 4 und die Lauf¬ sohle 5 z.B. aus Polyethylen vervollständigen die Bestand¬ teile des Rohskis, der nach seiner Verleimung in eine Form eingelegt und mit einer Hülle 6 aus elastomerem Kunststoff, z.B. Polyurethan, vorzugsweise im RIM-Verfahren umformt wird. Durch die bei diesem Verfahren im Formhohlraum herrschenden Drücke des noch flüssigen Hüllenmaterials dringt dieses mehr oder weniger tief in das mindestens teilweise poröse Schaum¬ stoffmaterial der Seitenteile 3' des Kernes ein.The ski shown in cross-section consists of the upper flange 1 made of light metal, the lower flange with a light metal layer 2 and an additional belt layer 2 'made of glass fiber laminate, the core with a middle part 3 made of wood and side parts 3' made of at least the cover 6 facing edge zone of porous foam, for example made of polyurethane glass fiber composite foam, preferably with a density of about 0.1 to about 0.3 or 0.5 g / cm 3 . Steel edges 4 and the outsole 5, for example made of polyethylene, complete the components of the raw ski, which after its gluing is placed in a mold and shaped with a cover 6 made of elastomeric plastic, for example polyurethane, preferably using the RIM process. As a result of the pressures of the still liquid shell material prevailing in the mold cavity during this process, it penetrates more or less deeply into the at least partially porous foam material of the side parts 3 'of the core.
Die Hülle 6 ist beim dargestellten Ausfuhrungsbeispiel eine einstückige Hülle, die die Seitenwangen und die Skioberfläche bildet. Weniger zweckmäßig, aber denkbar, wäre auch eine Hülle, bei der die Seitenwangen und die Skioberfläche getrennt sind.In the exemplary embodiment shown, the sleeve 6 is a one-piece sleeve which forms the side cheeks and the ski surface. A case in which the side cheeks and the ski surface are separated would also be less practical, but conceivable.
Beim dargestellten Ausfuhrungsbeispiel sind ferner nur die Seitenteile 3 * des Kerns aus wenigstens teilweise porösem Schaumstoffmaterial gebildet. Es können auch andere Kernteile oder der ganze Kern aus einem solchen Schaumstoffmaterial bestehen, in das dann beim Aufformen der Hülle (oder ihrer Teile) das noch flüssige Kunststoffmaterial der Hülle ein¬ dringt.
Die Erfindung kann sowohl bei Alpinskiern etwa gemäß Ausfüh¬ rungsbeispiel nach Fig. 1, aber auch bei anderen Skigattun¬ gen, z.B. bei Langlaufskiern, Sprungskiern, Firngleitern, Wasserskiern usw. angewendet werden, wobei der Aufbau des Rohskis der betreffenden Skigattung entsprechend gebildet ist. Beispielsweise sind bei den meisten der vorstehend aufgezählten Skigattungen die für Alpinskier nötigen Stahl¬ kanten entbehrlich, gegebenenfalls sogar die eine oder andere Gurtschicht. So können etwa die tragenden Bauteile im "Kern" integriert sein, der erfindungsgemäß wohl an seinen der Hülle zugewandten Randzonen aus porösem Schaumstoffmaterial besteht, im übrigen aber auch andere Werkstoffe enthalten kann. Dies wird in Fig. 2 durch einen Skiquerschnitt, der für einen Langlaufski geeignet wäre, veranschaulicht. Der zentrale Skikörper wird durch einen Kern 3" aus porösem, offenzelligem Schaumstoff gebildet, in dem tragende Teile in Form von Stäben 7 aus kunstharzgebundenen Rovingsträngen aus Glasfasern od.dgl. eingelegt sind. An seiner Unterseite trägt der Kern 3" eine Laufsohle 5 aus Kunststoff, die vor oder nach dem Aufformen der Hülle 6 mit dem Kern 3" verbunden wird. Der Rohski (Kern 3", Stäbe 7 und gegebenenfalls Lauf¬ sohle 5) wird nun in eine Form eingelegt und in der schon beim Ausführungsbeispiel nach Fig. 1 beschriebenen Weise mit einer Hülle 6 aus vorzugsweise elastomere Kunststoff um- hüllt, wobei das Hüllenmaterial in die Poren des Schaumstoff¬ materials des Kernes 3" eindringt, und zwar im Falle der Fig. 2 nicht nur an den Seitenflächen des Kernes 3", sondern teil¬ weise auch an der Oberseite des Kernes 3" (zwischen und neben den tragenden Stäben 7) .
In the exemplary embodiment shown, only the side parts 3 * of the core are formed from at least partially porous foam material. Other core parts or the entire core can also consist of such a foam material, into which the still liquid plastic material of the shell then penetrates when the shell (or its parts) is molded on. The invention can be used both in alpine skis, for example in accordance with the exemplary embodiment according to FIG. 1, but also in other ski types, for example in cross-country skis, jump skis, firing gliders, water skis, etc., the structure of the raw skis being formed appropriately for the type of ski concerned. For example, in most of the ski types listed above, the steel edges required for alpine skis are unnecessary, possibly even one or the other belt layer. For example, the load-bearing components can be integrated in the "core", which according to the invention probably consists of porous foam material at its edge zones facing the shell, but can also contain other materials. This is illustrated in FIG. 2 by a ski cross-section that would be suitable for cross-country skiing. The central ski body is formed by a core 3 "made of porous, open-cell foam, in which load-bearing parts in the form of rods 7 made of synthetic resin-bonded roving strands made of glass fibers or the like are inserted. On its underside, the core 3" carries an outsole 5 made of plastic , which is connected to the core 3 ″ before or after the shell 6 is molded on. The raw ski (core 3 ″, rods 7 and optionally outsole 5) is now inserted into a mold and in the shape already in the embodiment according to FIG. 1 described manner with a sheath 6 made of preferably elastomeric plastic, the sheath material penetrating into the pores of the foam material of the core 3 ", in the case of FIG. 2 not only on the side surfaces of the core 3" but partly ¬ as well on the top of the core 3 "(between and next to the supporting rods 7).
