Abstract

A strip-shaped reinforcement insert for skis, which can be marketed as a semi-finished product and has a band-shaped metal body (6) embedded in a plastic strip (10) and provided with regularly arranged openings (8). The plastic strip protrudes laterally beyond the metal body and is, in addition, already designed as a ski sole or ski surface or appropriately clad.

Description

Die Erfindung betrifft eine streifenförmige Armierungseinlage für Skier gemäß dem ersten Teil des Anspruchs 1.The invention relates to a strip-shaped reinforcement insert for skis according to the first part of claim 1.

Beispielsweise aus der US-A-3 272 522, der US-A-3 329 437 und der DE-A-2014 025 sind bereits Armierungseinlagen für Skier in Form skelettartiger Metallprofile mit durchbrochenem Steg bekannt. Solche Metallprofile werden innerhalb des Skis in ihrem Stegbereich gewöhnlich in Kunstharz eingebettet, das damit eine feste, formschlüssige Verbindung eingeht. Indessen müssen die betreffenden Profile durch Taillierung und Krümmung der jeweiligen Skiform angepaßt sein, was ihre Herstellung aufwendig und teuer macht. Zudem können ihre Randflansche zu unerwünschten Versteifungen des Skis führen.For example from US-A-3 272 522, US-A-3 329 437 and DE-A-2014 025 reinforcement inserts for skis in the form of skeleton-like metal profiles with a perforated web are already known. Such metal profiles are usually embedded in the bridge area of the ski in synthetic resin, which thus forms a firm, form-fitting connection. In the meantime, the profiles in question must be adapted to the respective ski shape by the waist and curvature, which makes their production complex and expensive. In addition, their edge flanges can lead to undesirable stiffening of the ski.

Die DE-A-30 31 498 zeigt einen Wasser- und das DE-U-82 03 861 einen Langlaufski mit einer als Halbfabrikat lieferfähigen Armierungseinlage, bestehend aus einem durchbrochenen Metallband gleichmäßiger Breite, die geringer ist als die minimale Breite des Skis. Derartige Bänder sind dazu vorgesehen, allseitig umschlossen in den Ski eingebettet zu werden. Zweckmäßigerweise wird dabei je ein Band in der Nähe der Ober- und der Unterseite des Skis angeordnet, um die dort infolge der Biege- und Torsionsbeanspruchungen auftretenden Kräfte aufzunehmen. Daneben finden in der Skiherstellung gemäß AT-A-347 831 Metalleinlagen in Form durchgehender Leichtmetallbleche Verwendung, die gewöhnlich bereits in Verbindung mit den im Skiaufbau angrenzenden Schichten, dem Skigrundriß entsprechend abgerichtet werden. Vor allem im letzteren Fall ist die feste Einbindung in den Ski problematisch derart, daß die von der Einlage aufzunehmenden Kräfte in diese eingeleitet werden können und daß der Ski nicht der Gefahr unterliegt, sich in Vertikalrichtung aufzulösen. Dies gilt umso mehr, als das bis an die Skiseitenflächen heranreichende Blech von dort her Temperaturdifferenzen rasch in den Ski einzuleiten vermag, die dort zu Wärmespannungen führen, und obgleich man gewöhnlich die betreffenden Bleche vor ihrer Weiterverarbeitung mit einem Haftvermittler beschichtet. Darüber hinaus hat sich das Leichtmetallblech in vielen Fällen als zu unelastisch erwiesen, indem es zu bleibenden Verformungen kam.DE-A-30 31 498 shows a water ski and DE-U-82 03 861 a cross-country ski with a reinforcement insert which can be supplied as a semi-finished product, consisting of a perforated metal band of uniform width, which is less than the minimum width of the ski. Such tapes are intended to be embedded in the ski on all sides. A band is expediently arranged in the vicinity of the top and the bottom of the ski in order to absorb the forces occurring there as a result of the bending and torsional stresses. In addition, metal inserts in the form of continuous light metal sheets are used in ski manufacture in accordance with AT-A-347 831, which are usually already prepared in accordance with the ski floor plan in connection with the layers adjoining the ski construction. Especially in the latter case, the fixed integration in the ski is problematic in such a way that the forces to be absorbed by the insert can be introduced into it and that the ski is not subject to the risk of dissolving in the vertical direction. This is all the more true since the sheet metal reaching up to the ski side surfaces can quickly introduce temperature differences into the ski from there, which lead to thermal stress there, and although the sheets in question are usually coated with an adhesion promoter before they are processed further. In addition, the light metal sheet has proven to be too inelastic in many cases due to permanent deformations.

Aus dem Prospekt 82/83 der Firma A. Rohrmoser, A-5602 Wagrain, ist eine als solche vorfertigbare Armierungseinlage gemäß dem ersten Teil des Anspruchs 1 bekannt, bei der ein gelochtes Stahlband in ein beidseitig darüber überstehendes Kunststoffband einlaminiert ist. Diese Armierungseinlage soll etwa in der halben Höhe des Skikörpers Anwendung finden.Brochure 82/83 from A. Rohrmoser, A-5602 Wagrain, discloses a reinforcement insert that can be prefabricated as such, according to the first part of claim 1, in which a perforated steel strip is laminated into a plastic strip that projects beyond it on both sides. This reinforcement insert should be used at about half the height of the ski body.

Schließlich ist aus der CH-A-368 402 ein im wesentlichen aus thermoplastischem Kunststoff bestehender Ski bekannt, bei dem zum einen zwei im wesentlichen die gesamte Skibreite einnehmende gelochte Stahlbänder in der Nähe der Skisohle bzw. der Skioberfläche (Deckfläche) angeordnet sind, zum anderen der betreffende Kunststoff, vorzugsweise hochmolekulares Polyethylen, auch bereits eine hohe Gleit- und Widerstandsfähigkeit aufweisen soll, vermutlich um selbst die Lauffläche des Skis zu bilden.Finally, from CH-A-368 402 a ski consisting essentially of thermoplastic material is known, in which on the one hand two perforated steel strips which essentially take up the entire ski width are arranged in the vicinity of the ski sole or the ski surface (top surface), and on the other hand the plastic in question, preferably high molecular weight polyethylene, should already have a high level of sliding and resistance, presumably in order to form the tread of the ski itself.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine streifenförmige Armierungseinlage gemäß dem ersten Teil des Anspruchs 1 so auszubilden, daß sie nicht nur die Einbindung des bandförmigen Metallkörpers in den Ski erleichtert bzw. verbessert, sondern darüber hinaus der Notwendigkeit enthebt, eine eigene Laufsohlen- oderSkioberflächenschicht vorzusehen.Proceeding from this, the object of the invention is to design a strip-shaped reinforcement insert according to the first part of claim 1 in such a way that it not only facilitates or improves the integration of the band-shaped metal body in the ski, but also removes the need to have one's own outsole. or to provide a ski surface layer.

Diese Aufgabe ist in zwei Alternativen durch die kennzeichnenden Merkmale der Ansprüche 1 und 2 gelöst.This object is achieved in two alternatives by the characterizing features of claims 1 and 2.

Mit der Erfindung ist ein preiswertes Halbfabrikat geschaffen, das bei einem hohen Qualitätsanforderungen genügenden Ski dessen Herstellung beträchtlich vereinfacht. Dabei geht die Erfindung davon aus, daß ja eine solche Armierungseinlage ohnedies am zweckmäßigsten, wie bereits bekannt, in der Nähe der Skisohle und/oder der Skioberfläche, mithin im Abstand von der neutralen Faser des Skikörpers, angeordnet wird.With the invention, an inexpensive semi-finished product is created, which considerably simplifies the manufacture of a ski that meets high quality requirements. The invention is based on the fact that such a reinforcement insert is most expedient anyway, as already known, in the vicinity of the ski sole and / or the ski surface, and consequently at a distance from the neutral fiber of the ski body.

In soweit bekannter Weise kann die erfindungsgemäße Armierungseinlage in Standardbreite in den Skikörperrohling eingearbeitet und erst anschließend, zusammen mit den übrigen Schichten, am Rand beschnitten werden. Dabei wird der Metallkörper in aller Regel eine Breite aufweisen, die geringer ist als die geringste Breite des fertigen Skikörpers.As far as is known, the reinforcement insert according to the invention can be incorporated into the blank of the ski body in standard width and only then, along with the other layers, can be trimmed at the edge. The metal body will usually have a width that is less than the smallest width of the finished ski body.

Die abhängigen Ansprüche geben vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung an.The dependent claims indicate advantageous design options of the invention.

Nachfolgend werden entsprechende Ausführungsbeispiele genauer beschrieben. Dabei zeigt

  • Fig. 1 eine Draufsicht auf einen Abschnitt einer erfindungsgemäßen Armierungseinlage, wobei auf der linken Seite die aufeinanderliegenden Schichten nacheinander abgebrochen erscheinen, und
  • Fig. 2 eine vergrößerten vertikalen Längsschnitt durch eine erfindungsgemäße Armierungseinlage.
Corresponding exemplary embodiments are described in more detail below. It shows
  • Fig. 1 is a plan view of a portion of a reinforcing insert according to the invention, wherein the layers lying one on top of the other appear broken off one after the other, and
  • Fig. 2 is an enlarged vertical longitudinal section through a reinforcing insert according to the invention.

Die in Fig. 1 gezeigte Armierungseinlage besteht aus einer unteren bandförmigen Schicht 2 und einer oberen bandförmigen Schicht 4 eines ggf. selbst wiederum armierten Kunststoffes, wie z. B. Epoxidharz, wozwischen ein schmälerer bandförmiger Metallkörper 6 eingelagert ist. Die obere Schicht 4 ist entsprechend einer gewünschten Skioberflächenstruktur behandelt und dazu ggf. beschichtet und/oder eingefärbt.The reinforcement insert shown in Fig. 1 consists of a lower band-shaped layer 2 and an upper band-shaped layer 4 of a plastic that may itself be reinforced, such as, for. B. epoxy, where a narrower band-shaped metal body 6 is embedded. The upper layer 4 is treated according to a desired ski surface structure and, if necessary, coated and / or colored for this purpose.

Die Armierung kann beispielsweise aus Glas-oder Kohlenstoffasern oder -gewebe bestehen. Der Metallkörper 6 weist zueinander versetzte Durchbrechungen 8, hier in Gestalt von kreisrunden Löchern mit einem Durchmesser von 4 mm auf. Die Breite des Metallkörpers 6 beträgt in dem gezeigten Beispiel für die Verwendung in Alpinskiern 50 mm, diejenige des aus den beiden Kunststoffschichten 2 und 4 bestehenden Bandes 10 90 mm. Das Kunststoffband 10 ist jedenfalls breiter als die maximale Breite des Skis, während diejenige des Metallkörpers 6 geringer als die minimale Breite des Skis ist, so daß das Kunststoffband 10 im Bedarfsfall die gesamte Breite des Skis einnehmen kann (es wird bei der Skiherstellung entsprechend abgerichtet), während der bandförmige Metallkörper 6 auf der ganzen Länge in den Ski eingebettet bleibt.The reinforcement can consist, for example, of glass or carbon fibers or fabrics. The metal body 6 has openings 8 offset from one another, here in the form of circular holes with a diameter of 4 mm. The width of the metal body 6 is in the example shown for use in alpines kiern 50 mm, that of the band consisting of the two plastic layers 2 and 4 10 90 mm. The plastic band 10 is in any case wider than the maximum width of the ski, while that of the metal body 6 is less than the minimum width of the ski, so that the plastic band 10 can take up the entire width of the ski if necessary (it is appropriately dressed during ski manufacture) , while the band-shaped metal body 6 remains embedded over the entire length in the ski.

Um eine Einbindung in das Kunststoffband 10 noch zu verbessern, kann der Metallkörper 6 in an sich bekannter Weise mit einem Haftvermittler beschichtet sein. Die beiden Kunststoffschichten 2 und 4 sind durch Verkleben, Verschweißen oder dergl. miteinander verbunden, wobei der Kunststoff bzw. das Bindemittel die Durchbrechungen 8 ausfüllt. Auf diese Weise besteht zwischen Metallkörper 6 und Kunststoffband 10 eine formschlüssige Verbindung, während auch die beiden Schichten 2 und 4 des Kunststoffbandes fest aufeinandergehalten werden. Die Durchbrechungen 8 sollten so klein wie möglich bemessen werden, solange noch Gewähr dafür gegeben ist, daß der Kunststoff bzw. das Bindemittel die Durchbrechungen voll ausfüllt.In order to improve the integration into the plastic band 10, the metal body 6 can be coated with an adhesion promoter in a manner known per se. The two plastic layers 2 and 4 are connected to one another by gluing, welding or the like, the plastic or the binder filling the openings 8. In this way, there is a positive connection between the metal body 6 and the plastic band 10, while the two layers 2 and 4 of the plastic band are also held firmly together. The openings 8 should be dimensioned as small as possible, as long as there is still a guarantee that the plastic or the binder completely fills the openings.

Fig. zeigt, wie auf das Kunststoffband 10 unterseitig noch eine separate Laufsohlenschicht 12 auflaminiert ist. Alternativ hierzu kann die Unterseite des Kunststoffbandes 10 bei Wahl eines hierzu geeigneten Kunststoffs auch selbst unmittelbar als Laufsohle ausgebildet sein, ebenso wie die Oberseite entsprechend einer gewünschten Skioberfläche gestaltet und/oder beschichtet sein könnte.Fig. Shows how a separate outsole layer 12 is laminated on the underside of the plastic band 10. As an alternative to this, the bottom side of the plastic band 10 can also be designed directly as an outsole when a suitable plastic is selected, just as the top side could be designed and / or coated according to a desired ski surface.

Vorzugsweise handelt es sich bei dem Metallkörper 6 um ein Federstahlband, dessen Dicke im Falle von Alpinskiern zwischen 0,2 und 0,3 mm, im Falle von Langlaufskiern zwischen 0,1 und 0,2 mm beträgt. Die Dicke des Kunststoffbandes 10 wird in der Regel zwischen 0,5 und 1 mm liegen. Für Alpinskier wird die Breite des Metallkörpers 6 zwischen 40 und 60 mm, für Langlaufskier, die mit recht unterschiedlichen (Minimal-)Breiten angeboten werden, zwischen 10 und 40 mm betragen.The metal body 6 is preferably a spring steel strip, the thickness of which is between 0.2 and 0.3 mm in the case of alpine skis and between 0.1 and 0.2 mm in the case of cross-country skis. The thickness of the plastic band 10 will generally be between 0.5 and 1 mm. For alpine skis, the width of the metal body 6 will be between 40 and 60 mm, for cross-country skis, which are offered with quite different (minimum) widths, between 10 and 40 mm.

Ein zusätzlicher Verankerungseffekt des Metallkörpers 6 in dem Kunststoffband 10 kann dadurch erreicht werden, daß die Durchbrechungen 8, wie dies auch in Fig. gestrichelt angedeutet ist, Grate 14 aufweisen. Im übrigen kann der Metallkörper 6, wie dies in Fig. 1 zu erkennen ist, beidseitig durchgehende, d. h. im wesentlichen ununterbrochene Ränder 16 besitzen, die ihn in besonderem Maße geeignet machen, ohne bleibende Verformungen hohe Zugkräfte aufzunehmen. Es können diese Ränder jedoch, wie in der Figur 1 gleichfalls zu erkennen, gezahnt sein, um ihre Einbindung in das Kunststoffband zu begünstigen.An additional anchoring effect of the metal body 6 in the plastic band 10 can be achieved in that the openings 8, as is also indicated in dashed lines in FIG. 1, have ridges 14. Otherwise, as can be seen in FIG. 1, the metal body 6 can be continuous on both sides, i. H. have essentially uninterrupted edges 16 which make it particularly suitable for absorbing high tensile forces without permanent deformations. However, as can also be seen in FIG. 1, these edges can be serrated in order to promote their integration into the plastic band.
