Abstract

The reinforcement is made as a grid plate from thermoplastic material supported by leg sections formed on it's sides and by thorns formed on in the centre and pointing upwards providing an elastic pre-tension between sole and upper layer. The grid rods converge in a downward direction like cutters. A ski is mfd. from hardened foam material ensuring that the installation screws of the ski binding find a secure hold without reducing the elasticity of the ski.

L)ic Erfindung betrifft einen beiderseits beschichteten Hart-:chaum-Ski, der im Bindungsbereich eine Verstärkung aufweist, di< den Montageschrauben der Bindung einen besseren Halt geben soll. Dazu ist es bekannt, auf die Unterseite der aus Glasfaser-Laminat bestehenden oberen Beschichtung eine zusätzliche Laminat-Platte zu kleben, die sich über den Einschraubbereich der später zu montierenden Skibindung erstreckt. Dadurch findet aber das selbatschneidende Gewinde der Montage schrauben nur in seinem obersten Reich festen Halt, so daß die Schrauben bei starker ßeanspruchung der Bindung trotzdem ausreißen können. Das bedeutet eine zusätzliche Unfallgefahr für den Skiläufer, und die iugebrochene Schraube reißt einen kegelförmigen Teil des Hartschaumkernes mit heraus. Ein so beschädigter Ski kann nicht mehr repariert werden. Auch beeinträchtigt das Verstärkungs-Laminat die Elastizität des Skis in seinem mittleren Bereich.The invention relates to a hard and foam ski, coated on both sides, which has a reinforcement in the binding area, di <the mounting screws of the Bonding should give a better hold. It is known for this on the underside the top coating made of fiberglass laminate is an additional laminate plate to glue, which extends over the screw-in area of the ski binding to be mounted later extends. As a result, however, the self-tapping thread of the assembly finds screws only firm hold in its uppermost realm, so that the screws can be used under heavy stress the bond can still tear away. This means an additional risk of accidents for the skier, and the broken screw tears a conical part of the rigid foam core with out. Such a damaged ski can no longer be repaired will. The reinforcement laminate also affects the elasticity of the ski its middle range.

Aufgabe der Erfindung ist es dem-gegenüber, die Verstärkung im ßindungsbereich eines beschichteten Ilartschaum-Skis so auszuführen, ciaß die Montageschrauben der Bindung über ihre volle Einschraubtiefe einer sicheren Ifalt finden und trotzdem die Elastizität des Skis nicht beeinträchtigt ist.The object of the invention, on the other hand, is to provide reinforcement in the binding area of a coated Ilartschaum ski so that the mounting screws of the Find a binding over its full screw-in depth and still find a safe ifalt the elasticity of the ski is not impaired.

Erfindungsgemäß ist die Verstärkung ausgeführt als Gitterplatte au; thermoplastischem Material, die mit ihr seitlich angeformten Dein und mittig nach oben angeformten Dornen unter elastischer Vorspannung zwischen Sohle und Oberschicht abgestützt ist.According to the invention, the reinforcement is designed as a grid plate au; thermoplastic material, which is molded on the side with it and in the middle Thorns molded on top with elastic pretension between sole and upper layer is supported.

ßei der Herstellung des Skis werden zunächst in bekannter Weise die Sohle und die Oberschicht in der geöffneten Spritzform eingespannt. Dann wird die Gitterplatte im Bindungsbereich eingelegt, und die orm wird geschlossen. Dadurch entsteht die erwähnte elastische Verformung in der Gitterplatte, so daß diese sich mit ihren Beinen gegen die Sohle und ihren Dornen gegen die Oberschicht verklemmt, wobei die Gitterplatte einen geringen Abstand zur Oberschicht des späteren Skis behält und durch das nachfolgende Einspritzen von selbstschäumenden Polyurethan nicht weggedrückt werden kann.During the manufacture of the ski, the The sole and the upper layer are clamped in the open injection mold. Then the Grid plate is inserted in the binding area and the orm is closed. Through this arises the mentioned elastic deformation in the grid plate, so that they have their legs against the sole and their thorns against the upper class jammed, with the grid plate a small distance to the top layer of the later Skis retains and through the subsequent injection of self-foaming polyurethane cannot be pushed away.

Damit dabei die Spritzmasse leichter durch die Gitteröffnungen treten und den Raum zwischen Gitterplatte und oberer Beschichtung gut ausfüllen kann, sind in Weiterbildung der Erfindung die Gitterstäbe nach unten schneidenförmig konvergierend ausgeführt.So that the spray compound can pass through the grid openings more easily and can fill the space between the grid plate and the top coating well In a further development of the invention, the bars converging downward in the shape of a cutting edge executed.

Die Erfindung möge anhand des in den Figuren schematisch dargestellten Ausführungsbeispieles veranschaulicht werden.The invention may be based on what is shown schematically in the figures Embodiment are illustrated.

Es zeigen Figur 1 eine Draufsicht und Figur 2 einen Querschnitt im Bindungsbereich.1 shows a plan view and FIG. 2 shows a cross-section in Binding area.

Das Ausführungsbeispiel ist ein Langlauf-Ski, der bekanntlich in allen Bereichen eine besonders große gleichmäßige elastische Nachgiebigkeit haben muss.The embodiment is a cross-country ski, which is known in all Areas must have a particularly large uniform elastic resilience.

Sein Kern 1 besteht aus Polyurethan-Hartschaum, seine Deckschicht 2 aus Glasfaser-Polyester-Laminat, auf Papier geschichtet, seine Sohle 3 aus unterseitig geschupptem Polyäthylen-Glasfaser-Laminat,dessen obere dem Kern 1 zugekehrte Fläche mit einem Glasfaser-vlies 4 ilegt ist.Its core 1 consists of rigid polyurethane foam, its top layer 2 made of fiberglass-polyester laminate, layered on paper, its sole 3 made of underside flaky polyethylene-glass fiber laminate, the upper surface of which faces the core 1 is laid with a glass fiber fleece 4.

Im Bindungsbereich ist die Gitterplatte 5 aus thermoplastischem Material eingespannt, indem sie mit ihren seitlichen Beinen 6 auf die Sohle 3 und mit ihren mittig nach oben angeformten Dornen 7 auf die Deckschicht 1 drückt und sich dadurch nach unten etwas durchwölbt; der Deutlichkeit halber in der Zeichnung übertrieben dargestellt.In the binding area, the grid plate 5 is made of thermoplastic material clamped by placing their side legs 6 on the sole 3 and with their centrally upwardly molded mandrels 7 presses on the cover layer 1 and thereby slightly arched downwards; exaggerated in the drawing for the sake of clarity shown.

Die Gitterstäbe 8 konvergieren schneidenförmig nach unten.The bars 8 converge downward in the shape of a cutting edge.

Die Zeichnung zeigt auch eine eingedrehte Bindungs-Montageschraube 9, nicht aber die zugehörige Bindung. Das selbstschneidende Schraubengewinde dringt durch eine der Gitteröffnungen. Wenn die Schraube nun auf Zug beansprucht ist, wird diese Haltekraft auf den dem Gewinde benachbarten Kernbereich übertragen und durch die Gitterplatte 5 großflächig und schonend auf die weiter entfernten Bereiche des Kernes 1 verteilt, so daß die Montageschraube auch dann nicht ausreißen kann, wenn der Kern aus spezifisch leichtem Ilurtschaum besteht, was für einen Langlauf-Ski vor allem erwünscht ist.The drawing also shows a screwed-in binding mounting screw 9, but not the associated bond. The self-tapping screw thread penetrates through one of the grid openings. If the screw is now under tension, will this holding force is transferred to the core area adjacent to the thread and through the grid plate 5 over a large area and gently on the more distant areas of the Core 1 distributed so that the mounting screw can not tear even if the core consists of specifically light Ilurt foam, what a cross-country ski above all is desirable.
