Description

Die Erfindung betrifft ein Skiherstellungsverfahren und einen Ski, der gem. diesem Verfahren hergestellt ist. Während früher Skier aus mehreren Holzschichten hergestellt wurden, bestehen diese heute aus Schichten sehr unterschiedlichen Materials, zumeist Kunststoff, Metall und ggf. auch Holz.The invention relates to a ski manufacturing process and a ski that according to. this process is made. While skis were previously made from several layers of wood, today they consist of layers of very different materials, mostly plastic, metal and possibly also wood.

Bei der Skiherstellung müssen diese Schichten in geeigneter Weise miteinander verbunden werden. Dabei werden die einzelnen Schichten in zumeist sehr komplexen Verfahren miteinander ver­bunden, die umständlich und kostspielig sind.When making skis, these layers have to be connected in a suitable manner. The individual layers are connected to each other in mostly very complex processes that are cumbersome and expensive.

Es stellt sich somit die Aufgabe, ein Verfahren zur Herstellung eines Skis an die Hand zu geben, durch das die einzelnen Schichten in einfacher und kostengünstiger Weise miteinander ver­bunden werden können.It is therefore the task of providing a method for producing a ski by means of which the individual layers can be connected to one another in a simple and inexpensive manner.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentan­spruchs 1 gelöst. Das im Anspruch 1 mitgeteilte Verfahren be­steht im wesentlichen aus zwei Verfahrensschritten. Im ersten Verfahrensschritt wird ein Skioberteil in einer eigens dafür vor­gesehenen Form gefertigt, das anschließend in einem zweiten Ver­fahrensschritt mit einem Skiunterteil gängiger Bauart verbunden wird. Das im Formverfahren hergestellte Skioberteil besteht z.B. aus einer Deckschicht, einem Kern und seitlich eingelegten Seitendämpferschichten. Dabei wird während des Formvorgangs die Deckschicht derart geformt, daß diese flanschartige Ränder bildet, die bei der Montage auf den Skiunterteil auf diesen aufliegen, so daß beim zweiten Verfahrensschritt, dem Verbinden des Skiunterteils mit dem Skioberteil eine zusätzliche Verbindung beider Teile über die flanschartigen Ränder möglich ist.The object is achieved by the features of claim 1. The method communicated in claim 1 essentially consists of two process steps. In the first process step, a ski upper part is manufactured in a form provided for this purpose, which is then connected in a second process step to a ski lower part of the common type. The ski top manufactured in the molding process consists e.g. consisting of a cover layer, a core and laterally inserted side damper layers. The cover layer is shaped during the molding process in such a way that it forms flange-like edges which rest on the lower part of the ski during assembly, so that in the second process step, connecting the lower part of the ski to the upper part of the ski, an additional connection of the two parts via the flange-like edges is possible is.

Das Skioberteil kann aber auch ohne Kern und seitlich eingelegte Seitendämpferschichten vorgefertigt werden. In diesem Fall können das einzeln vorgefertigte Ski-Oberteil und Ski-Unterteil in vorteilhafter Weise dadurch verbunden werden, daß der frei gebliebene Kernbereich des Ski-Oberteils beispielsweise mit Polyurethan oder einem ähnlichen Stoff ausgeschäumt wird. Damit wird in einem Verfahrensschritt der vorgefertigte Skioberteil mit dem vorgefertigten Skiunterteil verbunden und der hierdurch gebildete eingeschlossene Leerraum unter Bildung des Skikerns ausgeschäumt.The upper part of the ski can also be prefabricated without a core and laterally inserted side damper layers. In this case, the individually prefabricated upper part of the ski and lower part of the ski can be connected in an advantageous manner by foaming the free core area of the upper part of the ski, for example with polyurethane or a similar material. In this way, the prefabricated upper part of the ski is connected to the prefabricated lower part of the ski and the enclosed empty space formed thereby is foamed to form the core of the ski.

In vorteilhafter Weise werden die flanschartigen Ränder in kon­stanter Breite geformt und erst nach Entnahme aus der Form auf ihre endgültige Form gebracht, wobei der Überstand beispiels­weise weggefräst werden kann. Hierbei ergibt sich der Vorteil, daß für Skier, die in Draufsicht ein unterschiedliches Profil aufweisen, d.h. für deren Herstellung jeweils eigene Formen mit jeweils anders gestalteten Randbereichen bereitgestellt werden müßten, nur eine Form mit einem konstant gerade verlaufenden Rand vorhanden sein muß. Durch das zuvor geschilderte Fräsen der flanschartigen Ränder wird das Skioberteil dann an die jeweilige Form des Skiunterteils angepaßt. Dieses Skiunterteil kann be­liebiger Bauart sein. Beispielsweise besteht es aus einer durch Stahlkanten eingefaßten Polyäthylen-Lauffläche, über der ein Unterrgurt angeordnet ist.Advantageously, the flange-like edges are formed in a constant width and are brought to their final shape only after removal from the mold, it being possible for the excess to be milled away, for example. This has the advantage that for skis that have a different profile in plan view, that is, each with their own shapes for their manufacture differently designed edge areas would have to be provided, only one shape with a constant straight edge must be present. Through the previously described milling of the flange-like edges, the upper part of the ski is then adapted to the respective shape of the lower part of the ski. This lower part of the ski can be of any design. For example, it consists of a polyethylene tread bordered by steel edges, over which a lower belt is arranged.

Ein weiterer Vorteil ergibt sich daraus, daß in dem Formkasten der Form unterhalb der eine tragende Funktion ausübenden Deck­schicht eine Dekorschicht eingelegt ist, die nach Entnahme des Oberteils aus dem Formkasten natürlich auf der Oberfläche des Oberteils liegt. Dabei kann die Dekorschicht entweder nur die Oberfläche des Skioberteils oder aber die Oberfläche wie auch die Seitenkanten des Skioberteils abdecken.Another advantage results from the fact that a decorative layer is placed in the mold box of the mold below the cover layer which has a supporting function and which, of course, lies on the surface of the upper part after the upper part has been removed from the mold box. The decorative layer can either cover only the surface of the upper part of the ski or the surface as well as the side edges of the upper part of the ski.

Der Verfahrensschritt der Skioberteilformung kann in vorteil­hafter Weise dadurch ausgestaltet werden, daß die Deckschicht aus einer oder mehrerer Schichten besteht, die vor dem end­gültigen Formvorgang bei Umgebungsdruck und Umgebungstemperatur flexibel sind. Mit diesen flexiblen Schichten kann die Form aus­gelegt werden, bevor der Kern und die Seitendämpferschichten ein­gelegt werden. Für diese Verfahrensweise eignen sich Deck­schichten aus einem Epoxy-Prepreg oder einem Polyester-Prepreg der üblichen Handelsform.The process step of ski top shaping can be designed in an advantageous manner in that the cover layer consists of one or more layers which are flexible at ambient pressure and ambient temperature before the final molding process. With these flexible layers, the shape can be designed before the core and side damper layers are inserted. Covering layers made of an epoxy prepreg or a polyester prepreg of the customary commercial form are suitable for this procedure.

Nachdem die einzelnen Teile des Skioberteils in der Form ange­ordnet sind, und der Formkasten mit dem Formdeckel verschlossen sind, wird das Skioberteil bei geeigneter Temperatur und Druck durch Polymerisation zu einem stabilen Formkörper verbunden.After the individual parts of the upper part of the ski have been arranged in the mold and the molding box has been closed with the mold cover, the upper part of the ski is connected to a stable molded body at suitable temperature and pressure by polymerization.

Eine alternative Ausgestaltung des erfindungsgemäßen Verfahrens besteht darin, daß die Deckschicht aus einer in die Form einge­setzten Thermoplastschale besteht.An alternative embodiment of the method according to the invention consists in the fact that the cover layer consists of a thermoplastic shell inserted into the mold.

Als vorteilhaft erweist es sich, auch die fakultativ zusätzlich zur Deckschicht vorgesehene Dekorschicht als vor dem endgültigen Formvorgang bei Umgebungsdruck und Umgebungstemperatur flexible Schichten in den Formkasten zu legen. Dabei können wiederum Epoxy-Prepregs oder Polyester-Prepregs Anwendung finden.It proves to be advantageous to also place the decorative layer optionally provided in addition to the cover layer as flexible layers in the molding box before the final molding process at ambient pressure and temperature. Epoxy prepregs or polyester prepregs can in turn be used here.

Alternativ dazu kann aber auch die Dekorschicht als Thermoplast-­Schicht oder Thermoplast-Schale ausgeführt sein.Alternatively, however, the decorative layer can also be designed as a thermoplastic layer or thermoplastic shell.

Schließlich lassen sich in vorteilhafter Weise verbesserte Dämpfungseigenschaften gegenüber Längsschwingungen erreichen, wenn im Bindungsbereich des Skis zwischen der Deckschicht und dem Kern eine Dämpferschicht aus möglichst entropieelastischem Material, beispielsweise einem Elastomer, eingelegt wird. Mittels des zuvor näher ausgeführten Verfahrens zur Formung des Skioberteils läßt sich in einfacher Weise ein Ski herstellen, der ein Skioberteil aufweist, welches im Querschnitt trapez­förmig ist, wobei die Seitenflächen um einen konstanten Winkel geneigt sind.Finally, improved damping properties compared to longitudinal vibrations can advantageously be achieved if a damper layer made of the most entropy-elastic material, for example an elastomer, is inserted in the binding region of the ski between the cover layer and the core. By means of the previously described method for shaping the upper part of the ski, a ski can be produced in a simple manner which has a upper part of the ski which is trapezoidal in cross-section, the side surfaces being inclined at a constant angle.

Weitere Einzelheiten und Merkmale ergeben sich aus der Beschrei­bung von in der Zeichnung dargestellten Ausführungsbeispielen. Es zeigen:

Further details and features result from the description of exemplary embodiments shown in the drawing. Show it:
  • 1: a cross section through the upper part of the ski, which is produced by the method according to the invention, in the closed form;

In Fig. 1 ist der Formschritt des Skioberteils 10 in einer aus einem Formkasten 18 und einem Formdeckel 20 bestehenden Form dar­gestellt. Vor Verschließen des Formkastens 18 mit dem Formdeckel 20 wird zu unterst auf den Boden des Formkastens 18 eine Dekor­schicht 24 gelegt. Diese Dekorschicht 24 ist bei Umgebungsdruck und Umgebungstemperatur flexibel. Sie besteht aus einem Epoxy-­Prepreg oder alternativ dazu beispielsweise aus einem Polyester-­Prepreg.In Fig. 1, the molding step of the ski top 10 is shown in a form consisting of a mold box 18 and a mold cover 20. Before closing the molding box 18 with the molding lid 20, a decorative layer 24 is placed on the bottom of the molding box 18. This decorative layer 24 is flexible at ambient pressure and ambient temperature. It consists of an epoxy prepreg or alternatively, for example, of a polyester prepreg.

Auf diese Dekorschicht wird eine Deckschicht 12 in die Form ge­legt, die ebenfalls bei Umgebungsdruck und Umgebungstemperatur flexibel ist. Diese Deckschicht wird auch entlang der Seiten­wände, die gegenüber der senkrechten um einen Winkel α geneigt sind, gelegt. Am oberen Ende des Formkastens 18 wird die noch flexible Deckschicht 12 dann derart abgeknickt, daß sie einen flanschförmigen Rand 22 bildet. Da es sich bei der Deckschicht 12 um eine tragende Schicht handelt, ist diese bewehrt. Hierzu dienen beispielsweise faserbewährte Matten oder Carbon-Einlagen.A cover layer 12 is placed on this decorative layer, which is also flexible at ambient pressure and temperature. This cover layer is also laid along the side walls which are inclined at an angle α with respect to the vertical. At the upper end of the molding box 18, the still flexible cover layer 12 is then bent in such a way that it forms a flange-shaped edge 22. Since the cover layer 12 is a load-bearing layer, it is reinforced. For this purpose, fiber-proven mats or carbon inserts are used.

Auf diese Deckschicht wird ein Kern 14 gelegt, der aus einem be­liebigen für Kerne üblichen Skibaumaterial bestehen kann. Bei­spielsweise einem geschäumten Kunststoff. Zwischen dem Kern 14 und der seitlich hochgezogenen Deckschicht 12 werden im Quer­schnitt dreieckige Seitendämpferschichten 16 in die Form einge­legt. Diese Seitendämpferschichten 16 bestehen beispielsweise aus einem Elastomer und dienen zum seitlichen Schlagschutz des Kerns.A core 14 is placed on this cover layer, which can consist of any ski building material customary for cores. For example, a foamed plastic. Between the core 14 and the laterally raised cover layer 12, triangular side damper layers 16 are inserted into the mold in cross section. These side damper layers 16 are, for example Made of an elastomer and serve to protect the core from the side.

Nach Einbringen aller dieser Skibestandteil wird die Form mit dem Formdeckel 20 verschlossen und unter geeignetem Druck und bei geeigneter Temperatur ein Polymerisieren der einzelnen Schichten untereinander erreicht, so daß ein formstabiles Ski­oberteil 10 entsteht.After all of these ski components have been introduced, the mold is closed with the mold cover 20 and, under suitable pressure and at a suitable temperature, the individual layers are polymerized with one another, so that a dimensionally stable ski upper part 10 is produced.

Aus dem Längsschnitt der Fig. 2 kann ersehen werden, wie der Formkasten 18 entsprechend der Dickenverteilung über die Länge des Skioberteils geformt ist. Der Kern 14 des Skioberteils 10 ist der in Längsrichtung gesehenen Mitte des Skis dicker ausge­führt, d.h. genau in dem Bereich, in welchem später die Ski­bindung angeordnet wird. Zur Skimitte und zur Skischaufel hin, nimmt der Kern in seiner Dicke, wie in Fig. 2 dargestellt, ab.From the longitudinal section of FIG. 2 it can be seen how the molding box 18 is shaped according to the thickness distribution over the length of the upper part of the ski. The core 14 of the upper part 10 of the ski is made thicker from the longitudinal center of the ski, i.e. exactly in the area in which the ski binding will be arranged later. The thickness of the core decreases towards the center of the ski and towards the ski shovel, as shown in FIG. 2.

Nachdem durch das Formverfahren ein formstabiles Skioberteil er­halten wurde, wird dieses aus dem Formkasten 18 entnommen und die flanschförmigen Seitenränder 22 werden entsprechend der end­gültigen Form des Skis formgefräßt.After a shape-retaining ski upper part has been obtained by the molding process, it is removed from the molding box 18 and the flange-shaped side edges 22 are milled in accordance with the final shape of the ski.

Das so vorbereitete Ski-Oberteil wird auf ein Ski-Unterteil üb­licher Bauart (nicht dargestellt) aufgebracht und mit diesen in üblicher Weise verklebt. Zusätzlich kann zur besseren Verbindung das Ski-Oberteil 10 entlang des Flansches 22 mit üblichen Be­festigungsmitteln mit dem nicht dargestellten Ski-Unterteil ver­bunden werden. Das Ski-Unterteil kann beispielsweise aus einer Polyäthylen-Lauffläche bestehen, die mittels Stahlkanten einge­faßt ist, wobei oberhalb der Polyäthylen-Lauffläche üblicher­weise noch ein Untergurt angeordnet ist. Es kann aber auch ein beliebig anders aufgebautes Ski-Unterteil mit einem Ski-Oberteil 10, das gem. der zuvor beschriebenen Verfahrensfolge hergestellt wurde, verbunden werden.The upper ski part prepared in this way is applied to a lower ski part of a conventional type (not shown) and glued to it in the usual way. In addition, for a better connection, the upper ski part 10 can be connected to the lower ski part, not shown, along the flange 22 using conventional fastening means. The lower part of the ski can consist, for example, of a polyethylene tread which is bordered by means of steel edges, a lower flange usually being arranged above the polyethylene tread. But it can also be any lower ski with a ski upper 10, which according to. the previously described sequence of processes was connected.

In den Fig. 3 und 4 ist ebenfalls ein Ski-Oberteil 10 während des Formvorganges in der Form 18,20 dargestellt. Gem. diesem Aus­führungsbeispiel ist jedoch beim Verfahren zur Herstellung des Skis während des Verfahrensschritts des Aufbaus des Ski-Oberteils 10 ein weiterer Teilschritt hinzugefügt. Nach Auflegen der Deckschicht 12 und vor Einfügen des Kerns 14 wird im Bindungsbereich, d.h. in dem Bereich, auf dem später die Bindung aufgebracht wird, eine möglichst entropieelastische Dämpferschicht eingelegt. Diese besteht vorteilhaft aus einem Elastomer. Die Länge des Dämpfungselements 26 ist in Fig. 4 mit L bezeichnet. L kann typischerweise in einem Bereich von 500-700 mm variieren. Dabei hängt die Länge des Bereichs L u.a. von der Gesamtlänge des Skis ab.3 and 4, a ski upper part 10 is also shown in the mold 18, 20 during the molding process. According to this exemplary embodiment, however, a further substep is added to the method for producing the ski during the method step of assembling the upper ski part 10. After the covering layer 12 has been applied and before the core 14 has been inserted, the bond area, i.e. in the area on which the bond is later applied, an entropy-elastic damper layer as possible. This advantageously consists of an elastomer. The length of the damping element 26 is designated by L in FIG. 4. L can typically vary in a range of 500-700 mm. The length of the area L depends on on the total length of the ski.

Alternativ zu dem in den Figuren erläuterten Herstellungs­verfahren für das Ski-Oberteil, kann dies auch unter Freilassung eines entsprechenden Leerraums anstelle des eingelegten Kerns 14 und gegebenenfalls der Seitendämpferschichten 16 gebildet werden. Hierzu kann der Formdeckel 20 eine entsprechende Auswölbung (in den Figuren nicht dargestellt) aufweisen. Dieses modifizierte Ski-Oberteil wird mit einem Ski-Unterteil daraufhin verbunden, wobei gleichzeitig der leere Kernbereich beispielsweise mit Polyurethan oder einem ähnlichn Stoff ausgeschäumt wird.As an alternative to the manufacturing method for the upper part of the ski explained in the figures, this can also be formed by leaving a corresponding empty space instead of the inserted core 14 and optionally the side damper layers 16. For this purpose, the mold cover 20 can have a corresponding bulge (not shown in the figures). This modified ski upper part is then connected to a lower ski part, at the same time the empty core area is foamed, for example with polyurethane or a similar material.
