Description

Die Erfindung betrifft eine Foilanordnung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a foil arrangement according to the preamble of patent claim 1.

Foilboards werden beim Surfen sowie beim Kite- und Windsurfen eingesetzt und erlauben es, mit vergleichsweise kleinen Kites/Segelflächen auch bei sehr wenig Wind im Windbereich ab 2 Bft schneller als der Wind zu fahren. Aufgrund des während des Foilens äußerst geringen Strömungswiderstandes lassen sich selbst bei diesen geringen Windstärken Fahrgeschwindigkeiten erreichen, die herkömmlichen Surfboards, auch Raceboards deutlich überlegen sind. In jüngster Zeit werden auch SUP-Boards oder Boards zum Wellenreiten mit Foils ausgeführt, die es erlauben, bereits bei kleinen Wellen oder hinreichendem Vortrieb sich deutlich schneller als mit herkömmlichen Boards zu bewegen.Foilboards are used for surfing as well as for kite and windsurfing and make it possible to drive faster than the wind with comparatively small kites / sail areas even with very little wind in the wind range from 2 Bft. Due to the extremely low flow resistance during foiling, driving speeds can be achieved even with these low wind strengths, which are clearly superior to conventional surfboards and race boards. In recent times SUP boards or boards for surfing have also been made with foils, which make it possible to move much faster than with conventional boards even with small waves or sufficient propulsion.

Üblicherweise werden derartige Foilanordnungen mit ihrem Mast (auch Schaft-oder Kiel genannt) über eine Befestigungsplatte oder ein Boxsystem, wie beispielsweise eine Tuttle-Box, Future-Box oder dergleichen am Board befestigt.Usually, such foil arrangements are attached to the board with their mast (also called shaft or keel) via a fastening plate or a box system, such as a Tuttle box, future box or the like.

Entsprechende Foilanordnungen sind beispielsweise in der auf die Anmelderin zurückgehenden Druckschrift DE 10 2015 104 199 A1 beschrieben.Corresponding foil arrangements are for example in the document going back to the applicant DE 10 2015 104 199 A1 described.

Nachteilig an dieser bekannten Lösung ist, dass die Herstellung der Foilanordnung, insbesondere die Verbindung zwischen dem Mast und der Adapterplatte relativ aufwendig hergestellt wird. Üblicherweise wird die Adapterplatte mit dem Mast verschraubt, so dass diese bei Bedarf auswechselbar ist.The disadvantage of this known solution is that the production of the foil arrangement, in particular the connection between the mast and the adapter plate, is relatively complex. The adapter plate is usually screwed to the mast so that it can be exchanged if necessary.

Eine derartige Verschraubung bedarf eines hohen fertigungstechnischen Aufwandes, da die Passung zwischen der Aufnahme der Adapterplatte und dem Mast mit hoher Präzision ausgeführt werden muss. Ein weiterer Nachteil einer derartigen Verschraubung ist, dass sich diese beim Gebrauch lösen kann. Zur Überwindung dieses Nachteils sind auch Lösungen bekannt, bei denen der Mast und die Adapterplatte verschweißt sind.Such a screw connection requires a high level of manufacturing complexity, since the fit between the receptacle of the adapter plate and the mast has to be carried out with great precision. Another disadvantage of such a screw connection is that it can loosen during use. To overcome this Solutions in which the mast and the adapter plate are welded are also known disadvantageous.

Dem gegenüber liegt der Erfindung die Aufgabe zugrunde, eine Foilanordnung zu schaffen, die mit verringertem vorrichtungstechnischem Aufwand herstellbar ist.In contrast, the invention is based on the object of creating a foil arrangement which can be produced with reduced outlay in terms of device technology.

Diese Aufgabe wird durch eine Foilanordnung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a foil arrangement with the features of claim 1.

Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous further developments of the invention are the subject of the dependent claims.

Erfindungsgemäß hat die Foilanordnung einen Mast, der mittels eines Adapters oder einer Adapterplatte an einem Board, beispielsweise einem Kite-, Wellenreit-, SUP-oder einem Surfboard befestigbar ist und der an seinem von der Adapterplatte entfernten Endabschnitt eine Fuselage trägt, an der ein Frontwing und ein Rearwing befestigt sind. Erfindungsgemäß ist der Adapter/die Adapterplatte mit dem Mast verklebt. Die mit dem Mast verklebte Adapterplatte kann dann direkt mit dem Board verschraubt sein. Prinzipiell kann der Adapter bzw. die Adapterplatte auch in eine entsprechende, am Board befestigte Aufnahme eingesetzt werden.According to the invention, the foil arrangement has a mast which can be fastened to a board, for example a kite board, surf board, SUP board or a surfboard by means of an adapter or an adapter plate, and which carries a fuselage on its end section remote from the adapter plate, on which a front wing and a rear wing are attached. According to the invention, the adapter / adapter plate is glued to the mast. The adapter plate glued to the mast can then be screwed directly to the board. In principle, the adapter or the adapter plate can also be inserted into a corresponding receptacle attached to the board.

Eine derartige Lösung hat den Vorteil, dass bei entsprechender Fertigung der Adapterplatte und des Mastes eine dauerhaft spielfreie Verbindung herstellbar ist. Des Weiteren wird durch die dichte Verklebung verhindert, dass Sand oder sonstige Fremdstoffe in den Verbindungsbereich zwischen den Mast und der Adapterplatte eindringen können. Für den Fall, dass der Mast aus einem metallischen Werkstoff, beispielsweise Aluminium hergestellt ist, wird durch die Verklebung auch eine Korrosion im Anbindungsbereich an der Adapterplatte vermieden.A solution of this type has the advantage that, with appropriate production of the adapter plate and the mast, a permanently play-free connection can be established. Furthermore, the tight bonding prevents sand or other foreign matter from penetrating into the connection area between the mast and the adapter plate. In the event that the mast is made of a metallic material, for example aluminum, the gluing also prevents corrosion in the connection area on the adapter plate.

Bei einem Ausführungsbeispiel der Erfindung hat der Mast einen Endabschnitt, der derart ausgelegt ist, dass er passgenau in eine adapterplattenseitige Aufnahme einsetzbar ist.In one embodiment of the invention, the mast has an end section which is designed in such a way that it can be inserted precisely into a receptacle on the adapter plate side.

Dieser Endabschnitt kann das gleiche Profil wie der angeströmte Teil des Masts aufweisen. Zur Verbesserung der Abstützung kann dieser Endabschnitt jedoch auch mit einem anderen, hinsichtlich der Krafteinleitung optimierten Profil ausgeführt werden. Die adapterplattenseitige Aufnahme ist dann entsprechend ausgebildet, so dass eine passgenaue Aufnahme des Endabschnitts gewährleistet ist.This end section can have the same profile as the part of the mast against which the flow is flowing. To improve the support, however, this end section can also be designed with a different profile that is optimized with regard to the introduction of force. The receptacle on the adapter plate side is then designed accordingly, so that a precisely fitting receptacle of the end section is ensured.

Der Endabschnitt des Masts kann stirnseitig an einer Bodenfläche der Aufnahme oder an der Adapterplatte abgestützt sein.The end section of the mast can be supported at the end on a bottom surface of the receptacle or on the adapter plate.

Bei einem Ausführungsbeispiel der Erfindung ist die Fuselage mit dem Mast verschraubt, so dass die Foilanordnung zum Transport auf einfache Weise auseinander genommen werden kann.In one embodiment of the invention, the fuselage is screwed to the mast so that the foil arrangement can be taken apart in a simple manner for transport.

Dabei wird es besonders bevorzugt, wenn der Mast aus Aluminium oder einer Aluminiumlegierung besteht und die Fuselage aus Kunststoff, insbesondere aus faserverstärktem Kunststoff, wie kohlefaserverstärktem Kunststoff, hergestellt ist.It is particularly preferred if the mast is made of aluminum or an aluminum alloy and the fuselage is made of plastic, in particular fiber-reinforced plastic, such as carbon fiber-reinforced plastic.

Zur Vermeidung von Korrosion zwischen den Befestigungsschrauben und dem Mast werden gemäß einer vorteilhaften Weiterbildung der Erfindung in den Mast ein oder mehrere Edelstahl-Einsätze eingesetzt, die ihrerseits mit einem Schraubgewinde versehen sind. Die Schraubverbindung hat dann die gleiche Materialpaarung, so dass im Schraubbereich eine Korrosion zuverlässig vermieden wird und somit das einfache Lösen der Verbindung gewährleistet ist.To avoid corrosion between the fastening screws and the mast, according to an advantageous development of the invention, one or more stainless steel inserts are inserted into the mast, which in turn are provided with a screw thread. The screw connection then has the same material pairing, so that corrosion is reliably avoided in the screw area and thus the connection is easy to loosen.

Bei einem Ausführungsbeispiel der Erfindung ist vorgesehen, auch die Wings mit der Fuselage zu verschrauben. Auch diese Wings können aus einem faserverstärktem Kunststoff hergestellt werden.In one embodiment of the invention it is provided that the wings are also screwed to the fuselage. These wings can also be made from a fiber-reinforced plastic.

Das Fahrverhalten der Foilanordnung lässt sich weiter verbessern, wenn die Wings mit Winglets ausgeführt sind.The driving behavior of the foil arrangement can be further improved if the wings are designed with winglets.

Bei einem besonders einfach aufgebauten Ausführungsbeispiel der Erfindung ist die Adapterplatte ihrerseits mit dem Board verschraubt. Wobei diese Verschraubung direkt oder über ein geeignetes Boxsystem oder eine sonstige Aufnahme erfolgen kann, wobei das Boxsystem nach Art eines Future-Tuttle-/Minituttle-, FCS-, BFS- oder Finn-Plug-System oder dergleichen ausgebildet sein kann. Diese Systeme werden üblicherweise verwendet, um Finnen über geeignete Adapter in entsprechende Finnenboxen festzulegen.In a particularly simple embodiment of the invention, the adapter plate is in turn screwed to the board. Whereby this screw connection can take place directly or via a suitable box system or some other receptacle, wherein the box system can be designed in the manner of a Future Tuttle / Minituttle, FCS, BFS or Finn-Plug system or the like. These systems are usually used to fix fins in appropriate fin boxes using suitable adapters.

Ein bevorzugtes Ausführungsbeispiel der Erfindung wird im Folgenden anhand schematischer Zeichnungen näher erläutert. Es zeigen:

  • Figur 1 eine schematische Seitenansicht eines Boards mit einer angesetzten Foilanordnung;
  • Figur 2 eine Einzeldarstellung einer Foilanordnung für ein derartiges Board und
  • Figur 3 eine Detaildarstellung der Foilanordnung gemäß Figur 2.
A preferred embodiment of the invention is explained in more detail below with reference to schematic drawings. Show it:
  • Figure 1 a schematic side view of a board with an attached foil arrangement;
  • Figure 2 an individual representation of a foil arrangement for such a board and
  • Figure 3 a detailed representation of the foil arrangement according to Figure 2 .

Figur 1 zeigt eine Seitenansicht eines zum Surfen, Kiten, Wellenreiten oder Stehpaddeln ("SUPen") oder Windsurfen vorgesehenen Boards 1, an dem eine erfindungsgemäße Foilanordnung 2 befestigt ist. Diese hat einen Mast 4, der an seinem boardseitigen Endabschnitt eine Adapterplatte 6 trägt, die am Board befestigbar ist. Dabei wird unter dem Begriff "Adapterplatte" nicht notwendigerweise eine plattenförmige Struktur sondern jedweder Adapter verstanden, der in geeigneter Weise an dem Board befestigbar ist. Beim dargestellten Ausführungsbeispiel ist die Adapterplatte etwa plattenförmig ausgeführt und kann dann über Befestigungsmittel mit entsprechenden Schraubbuchsen verschraubt werden, die im Board aufgenommen sind. Anstelle dieser Inserts können auch üblicherweise bei Boards verwendete Finnenkasten-Systeme, wie beispielsweise ein Future-, Tuttle-/Minituttle-, FCS-, BFS-, oder Finn-Plug-System oder dergleichen verwendet werden, um die Adapterplatte beispielsweise über zwei Boxen am Board zu befestigen. Figure 1 shows a side view of a board 1 intended for surfing, kiting, surfing or stand-up paddling (“SUP”) or windsurfing, to which a foil arrangement 2 according to the invention is attached. This has a mast 4 which carries an adapter plate 6 on its board-side end section which can be fastened to the board. The term “adapter plate” does not necessarily mean a plate-shaped structure but any adapter that can be attached to the board in a suitable manner. In the exemplary embodiment shown, the adapter plate is designed approximately in the form of a plate and can then be screwed using fasteners with corresponding screw sockets that are received in the board. Instead of these inserts, fin box systems usually used in boards, such as a Future, Tuttle / Minituttle, FCS, BFS, or Finn-Plug system or the like, can be used to connect the adapter plate, for example via two boxes To attach board.

An dem vom Board 1 entfernten Endabschnitt des Masts 4 ist eine Fuselage 8 befestigt, die frontseitig einen Frontwing 10 und heckseitig einen Rearwing 12 trägt. Beide Wings 8, 12 sind jeweils mit Winglets 14, 16 versehen, wobei sich beispielsweise die Winglets 14 am Frontwing 10 nach unten und die Winglets 16 am Rearwing 12 nach oben erstrecken. Wie aus der Darstellung des Weiteren entnehmbar ist, ist das Frontwing 10 von unten her an eine nach unten gekrümmten Endabschnitt der Fuselage 8 angesetzt, der Rearwing 12 ist in umgekehrter Weise auf einem nach oben gekrümmten Endabschnitt der Fuselage 8 aufgesetzt.A fuselage 8 is attached to the end section of the mast 4 that is remote from the board 1 and carries a front wing 10 at the front and a rear wing 12 at the rear. Both wings 8, 12 are each provided with winglets 14, 16, for example the winglets 14 on the front wing 10 extending downwards and the winglets 16 on the rear wing 12 extending upwards. As can also be seen from the illustration, this is The front wing 10 is attached from below to a downwardly curved end section of the fuselage 8, the rear wing 12 is placed in the reverse manner on an upwardly curved end section of the fuselage 8.

Die Fuselage 8 ist mit dem Mast 4 verschraubt. Beim dargestellten Ausführungsbeispiel ist es vorgesehen, den Mast aus einer Aluminiumlegierung oder dergleichen herzustellen. Die Fuselage 8 und die beiden Wings 10, 12 bestehen vorzugsweise aus einem kohlefaserverstärktem Kunststoff. Werden nunmehr Edelstahlschrauben zum Befestigen der Fuselage 8 am Mast 4 verwendet, so entsteht zwischen den ins Aluminium eingebrachten Schraublöchern und den Edelstahlschrauben eine Korrosion, die dazu führen kann, dass die Fuselage nicht mehr oder nur mit hohem Aufwand vom Mast 4 getrennt werden kann. Um dies zu vermeiden, werden in den Mast Edelstahlgewindeinserts eingebracht, so dass der Gewindeeingriff lediglich zwischen der Materialpaarung Edelstahl/Edelstahl erfolgt und somit die geschilderten Korrosionsprobleme nicht auftreten können.The fuselage 8 is screwed to the mast 4. In the illustrated embodiment, it is provided that the mast is made of an aluminum alloy or the like. The fuselage 8 and the two wings 10, 12 are preferably made of a carbon fiber reinforced plastic. If stainless steel screws are now used to attach the fuselage 8 to the mast 4, corrosion occurs between the screw holes made in the aluminum and the stainless steel screws, which can mean that the fuselage can no longer be separated from the mast 4, or only with great effort. In order to avoid this, stainless steel threaded inserts are made in the mast so that the thread engagement only takes place between the material pairing of stainless steel / stainless steel and the corrosion problems described cannot occur.

Erfindungsgemäß ist der Mast 4 mit der Adapterplatte 6 verklebt. Dazu ist gemäß Figur 3 an der Adapterplatte 6 eine Aufnahme 18 ausgebildet, in die der endsprechende Endabschnitt des Masts 4 eingesetzt ist. Diese Aufnahme 18 kann, wie in Figur 3 dargestellt, als flanschförmige Aufnahme 18 ausgeführt sein, die sich zur Adapterplatte 6 hin verbreitert.According to the invention, the mast 4 is glued to the adapter plate 6. This is according to Figure 3 a receptacle 18 is formed on the adapter plate 6, into which the corresponding end section of the mast 4 is inserted. This recording 18 can, as in Figure 3 be designed as a flange-shaped receptacle 18 which widens towards the adapter plate 6.

Zur Aufnahme eines Endabschnitts 22 des Masts 4 ist die Aufnahme 18 mit einer entsprechend des hydrodynamisch optimierten Profils des Masts 4 ausgebildeten Tasche 24 ausgeführt, in die der Endabschnitt 22 mit einer Gleit- oder Presspassung eingesetzt wird. Vor diesem Einsetzen wird der Endabschnitt 22 und/oder die Tasche 24 mit einer dünnen Kleberschicht versehen, wobei sichergestellt sein sollte, dass diese Kleberschicht nach dem Einsetzen vollflächig aufgetragen bleibt. Das Einsetzen erfolgt derart, dass der Endabschnitt 22 seitlich an den gebogenen Umfangsflächen der Tasche 24 abgestützt ist. In Längsrichtung des Masts 4 erfolgt eine Abstützung auf einer Bodenfläche der Tasche 24. Prinzipiell kann die Aufnahme 18 auch nach unten, zur Adapterplatte 6 hin offen ausgeführt sein, so dass die adapterseitige Stirnfläche des Masts 4 dann flächig oder abschnittsweise auf der Adapterplatte 6 aufliegt.To accommodate an end section 22 of the mast 4, the receptacle 18 is designed with a pocket 24 designed according to the hydrodynamically optimized profile of the mast 4, into which the end section 22 is inserted with a slide or press fit. Before this insertion, the end section 22 and / or the pocket 24 is provided with a thin layer of adhesive, whereby it should be ensured that this layer of adhesive remains applied over the entire surface after insertion. The insertion takes place in such a way that the end section 22 is laterally supported on the curved circumferential surfaces of the pocket 24. In the longitudinal direction of the mast 4 there is a support on a bottom surface of the pocket 24. In principle, the receptacle 18 can also be designed to be open downwards, towards the adapter plate 6, so that the adapter-side end face of the mast 4 then rests flat or in sections on the adapter plate 6.

Prinzipiell kann der in die Aufnahme 18 eintauchende Teil des Endabschnitts 22 des Masts 4 auch mit einem von der hydrodynamisch optimierten "Tropfenform" abweichenden Profil abweichen und im Hinblick auf die maximale Abstützung des Masts optimiert werden. In diesem Fall hätte dann der in die Aufnahme 18 eintauchende Bereich des Endabschnitts 22 ein anderes Profil als der in Figur 3 sichtbare, nicht in die Aufnahme 18 eintauchende Bereich.In principle, the part of the end section 22 of the mast 4 that plunges into the receptacle 18 can also deviate with a profile deviating from the hydrodynamically optimized "teardrop shape" and be optimized with regard to the maximum support of the mast. In this case, the area of the end section 22 that plunges into the receptacle 18 would have a different profile than that in FIG Figure 3 visible, not immersed in the receptacle 18 area.

Die Aufnahme 18 kann jedoch auch etwa nach Art eines der oben genannten Systeme, beispielsweise nach Art einer Tuttlebox ausgeführt sein, so dass entsprechend der Endabschnitt des Mastes 4 als zu diesem System passender Adapter ausgebildet ist. Auf diese Weise lässt sich dieser Adapter passgenau in die Aufnahme 18 einsetzen.The receptacle 18 can, however, also be designed in the manner of one of the above-mentioned systems, for example in the manner of a Tuttlebox, so that the end section of the mast 4 is designed as an adapter that matches this system. In this way, this adapter can be inserted precisely into the receptacle 18.

Die Festlegung erfolgt dann mittels eines geeigneten hochfesten Klebers, der zum einen seewasserbeständig ist und zum anderen auch die beim Foilen auftretenden Belastungen aufnehmen und übertragen kann.It is then fixed by means of a suitable high-strength adhesive, which is seawater-resistant on the one hand and can also absorb and transfer the loads that occur during foiling on the other.

Diese Klebeverbindung ermöglicht es, die Foilanordnung 2 mit einem geringen vorrichtungstechnischen Aufwand herzustellen, wobei, wie vorstehend ausgeführt, das Eindringen von Schmutz in den Bereich der Aufnahme 18 zuverlässig verhindert werden kann, so dass die Foilanordnung 1 stets die vorbestimmte Relativposition am Board einnimmt. Bei dem dargestellten Ausführungsbeispiel hat die Adapterplatte 6 mehrere Ausnehmungen, durch die hindurch sich Befestigungsmittel erstrecken, in die entsprechende Schraubbuchsen des Boards eingeschraubt werden, so dass der Mast über die vergleichsweise große Fläche der Adapterplatte 6 an dem Board abgestützt ist.This adhesive connection makes it possible to produce the foil arrangement 2 with a low outlay in terms of device technology, whereby, as stated above, the penetration of dirt into the area of the receptacle 18 can be reliably prevented, so that the foil arrangement 1 always assumes the predetermined relative position on the board. In the exemplary embodiment shown, the adapter plate 6 has several recesses through which fastening means extend and are screwed into the corresponding screw sockets of the board so that the mast is supported on the board over the comparatively large area of the adapter plate 6.

Bei dem in Figur 2 dargestellten Ausführungsbeispiel ist es auch vorgesehen, den Rearwing 12 und/oder den Frontwing 10 auswechselbar an der Fuselage 8 zu befestigen.The in Figure 2 The illustrated embodiment, it is also provided that the rear wing 12 and / or the front wing 10 can be attached to the fuselage 8 in an exchangeable manner.

Offenbart ist eine Foilanordnung für ein Surf-, SUP-, Windsurf- oder Kitesurfboard, mit einem Mast, der mittels einer Adapterplatte an dem Board befestigt ist. An seinem vom Board entfernten Endabschnitt trägt der Mast eine Fuselage, an der ein Frontwing und ein Rearwing befestigt sind. Die Adapterplatte und der Mast sind erfindungsgemäß miteinander verklebt.Disclosed is a foil arrangement for a surf, SUP, windsurf or kitesurf board, with a mast that is attached to the board by means of an adapter plate. On his The end section remote from the board carries a fuselage to which a front wing and a rear wing are attached. According to the invention, the adapter plate and the mast are glued together.
