Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Erhö­hung des Auftriebs eines Segelbretts nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for increasing the buoyancy of a sailing board according to the preamble of claim 1.

Eine gattungsgemäße Vorrichtung ist aus dem DE-GM 83 22 936 bekannt. Sie dient zur Erhöhung des Auftriebs oder der Kippstabilität des Segelbretts (oder Surfbretts) und besteht im wesentlichen aus aufblasbaren Schläuchen, die das Segelbrett am Rand umgeben. Es kann auch eine Luftkammer im wesentlichen an der Oberseite des Segel­bretts angeordnet sein. Die Luftkammern sind mittels Gurten oder Auflageflächen am Segelbrett befestigt. Der­artige Vorrichtungen lassen sich raumsparend transportie­ren, bieten jedoch in Verbindung mit dem Segelbrett prak­tisch keine zusätzliche Fläche, um gewünschtenfalls das Segelbrett als Segelboot für mehrere Personen verwenden zu können oder es als aerodynamische Tragfläche zu nutzen. Darüber hinaus sind sie schwierig zu montieren.A generic device is known from DE-GM 83 22 936. It serves to increase the buoyancy or the stability of the sail board (or surf board) and essentially consists of inflatable tubes that surround the sail board at the edge. An air chamber can also be arranged essentially on the upper side of the sailing board. The air chambers are attached to the sailboard by means of straps or support surfaces. Devices of this type can be transported in a space-saving manner, but, in conjunction with the sail board, offer practically no additional area in order, if desired, to be able to use the sail board as a sailboat for several people or to use it as an aerodynamic wing. In addition, they are difficult to assemble.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der gattungsgemäßen Art so weiterzubilden, daß sie auf einfache Weise eine Umwandlung eines Segelbretts in ein kippstabiles Wasserfahrzeug für mehrere Personen gestat­tet, sie aber auch aufgrund ihrer Formgebung Auftrieb erzeugen kann und aerodynamisch getragene Sprünge mit dem Segelbrett ermöglicht.The invention has for its object to develop a device of the generic type so that it allows a conversion of a sailing board into a tilt-resistant watercraft for several people in a simple manner, but it can also generate buoyancy due to its shape and enables aerodynamically carried jumps with the sailing board .

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnen­den Merkmale des Anspruchs 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.

Eine solche Vorrichtung läßt sich leicht an einem Segel­brett anbringen, weil sie nach Einführung des Segelbretts in die Tasche praktisch nur aufgeblasen zu werden braucht. Sie bietet dann wenigstens zwei Personen eine hinreichend große form- und kippstabile Sitz- oder Liegefläche, sie bildet zugleich eine aerodynamische Tragfläche und sie läßt sich im nicht aufgeblasenen Zustand raumsparend transportieren.Such a device can be easily attached to a sail board because it practically only needs to be inflated after insertion of the sail board into the pocket. It then offers at least two people a sufficiently large stable and tilt-stable seating or lying surface, it also forms an aerodynamic wing and it can be transported in a space-saving manner when not inflated.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Vorzugsweise ist dafür gesorgt, daß sich die Tasche vom Bug bis nahe zu einem Schwertkasten für ein Schwert des eingeführten Segelbretts erstreckt und am Heckteil des Segelbretts Verbindungsmittel zum Befestigen der Matte vorgesehen sind. Die Verbindungsmittel sind durch Fuß­schlaufen des Segelbretts hindurchgeführte Gurte. Auf diese Weise kommt man mit einer in Längsrichtung des Segelbretts vehältnismäßig kurzen Tasche aus, im Gegen­satz zu einer das Segelbrett vollständig aufnehmenden Tasche. Dennoch ist durch die Verbindungsmittel für einen hinreichend sicheren Halt des Segelbretts in der Tasche gesorgt, ohne den Montageaufwand nennenswert zu erhöhen, da Fußschlaufen in der Regel an einem Segelbrett vorhanden sind. Gegebenenfalls liegt die Matte auf den Fußschlaufen auf und damit in einem Abstand von der Oberseite des Segelbretts. Dies hat den Vorteil, daß die Matte bei schneller Fahrt wenig oder gar keine Wasserberührung hat.It is preferably ensured that the pocket extends from the bow to close to a sword case for a sword of the inserted sailing board and connecting means are provided on the rear part of the sailing board for fastening the mat. The connecting means are belts which are passed through foot straps of the sailing board. In this way, one can manage with a pocket that is vehemently short in the longitudinal direction of the sail board, in contrast to a pocket that completely accommodates the sail board. Nevertheless, the connecting means ensure that the sailing board is held securely in the bag without significantly increasing the assembly effort, since foot straps are usually present on a sailing board. If necessary, the mat rests on the foot straps and thus at a distance from the top of the sailing board. This has the advantage that the mat has little or no water contact when driving fast.

Sodann ist es günstig, wenn in der aufblasbaren Matte Aus­sparungen zur Durchführung eines Mastfußes und des Schwer­tes des Segelbretts vorgesehen sind. Dies ermöglicht auf einfache Weise die Verwendung der Kombination aus Segelbrett und Vorrichtung als Segelboot.Then it is advantageous if recesses are provided in the inflatable mat for carrying a mast foot and the sword of the sailing board. this makes possible in a simple way the use of the combination of sailing board and device as a sailing boat.

Ferner kann die aufblasbare Matte in der Draufsicht die Form einer Deltafläche fit vorwärts gepfeilter Hinterkan­te haben. Dies trägt zur Verringerung des Strömungs­widerstands im Wasser bei. Die Deltaform der aufblasbaren Matte ist aber nicht nur hydrodynamisch vorteilhaft, sie erzeugt auch, insbesondere in Bodennähe, beträchtli­chen aerodynamischen Auftrieb. Dadurch werden größere Geschwindigkeiten möglich, wenn das Gewicht des Fahrzeugs zunehmend von Luft, statt von Wasser getragen wird. Mit der Vorrichtung in Form einer deltaförmigen aufblasbaren Matte ist es auch möglich, mit Segelbrettern wesentlich weitere und höhere Sprünge als bisher auszuführen, weil das Segelbrett in Verbindung mit der aufblasbaren Matte als aerodynamische Tragfläche wirkt.Furthermore, the top view of the inflatable mat can be in the form of a delta surface with a forward swept trailing edge. This helps to reduce the flow resistance in the water. The delta shape of the inflatable mat is not only hydrodynamically advantageous, it also generates considerable aerodynamic lift, especially near the ground. This enables higher speeds if the weight of the vehicle is increasingly carried by air instead of water. With the device in the form of a delta-shaped inflatable mat, it is also possible to make significantly more and higher jumps than previously with sail boards, because the sail board, in conjunction with the inflatable mat, acts as an aerodynamic aerofoil.

Insbesondere kann am Umfang der aufblasbaren Matte teil­weise ein Schlauch umlaufen, der zwei Schenkel aufweist, die die vordere Profilkante der Deltafläche bilden. Dies erleichtert die Herstellung der Matte in Form einer Delta­fläche. Weiterhin sind zwischen den Schenkeln des Schlau­ches sich in Längsrichtung der Deltafläche erstreckende Schläuche angeordnet.In particular, a hose can partially run around the circumference of the inflatable mat, which has two legs that form the front profile edge of the delta surface. This facilitates the production of the mat in the form of a delta surface. Furthermore, tubes extending in the longitudinal direction of the delta surface are arranged between the legs of the tube.

Vorzugsweise ist ferner dafür gesorgt, daß die Schläuche Schlauchkammern bilden, die durch Stege getrennt sind, die als aerodynamische Profile geschnitten sind, so daß Längsschnitte durch die aufblasbare Matte aerodynamisch tragende Profile ergeben. Dies erzeugt zusätzlich aerody­namischen Auftrieb.It is also preferably ensured that the tubes form tube chambers which are separated by webs which are cut as aerodynamic profiles, so that longitudinal cuts through the inflatable mat result in aerodynamically supporting profiles. This also creates aerodynamic lift.

Die aufblasbare Matte kann aus luftdichtem Material ge­klebt oder geschweißt sein. Bei dieser Ausbildung ist sie in größeren Stückzahlen auf einfache Weise herstellbar. auf einfache Weise die Verwendung der Kombination aus Segelbrett und Vorrichtung als Segelboot.The inflatable mat can be glued or welded from airtight material. With this design, it can be easily produced in large numbers. in a simple way the use of the combination of sailing board and device as a sailing boat.

Ferner kann die aufblasbare Matte in der Draufsicht die Form einer Deltafläche mit vorwärts gepfeilter Hinterkan­te haben. Dies trägt zur Verringerung des Strömungs­widerstands im Wasser bei. Die Deltaform der aufblasbaren Matte ist aber nicht nur hydrodynamisch vorteilhaft, sie erzeugt auch, insbesondere in Bodennähe, beträchtli­chen aerodynamischen Auftrieb.

Mit der Vorrichtung in Form einer deltaförmigen aufblasbaren Matte ist es auch möglich, mit Segelbrettern wesentlich weitere und höhere Sprünge als bisher auszuführen, weil das Segelbrett in Verbindung mit der aufblasbaren Matte als aerodynamische Tragfläche wirkt.Furthermore, the top view of the inflatable mat can be in the form of a delta surface with the rear edge swept forward. This helps to reduce the flow resistance in the water. The delta shape of the inflatable mat is not only hydrodynamically advantageous, it also generates considerable aerodynamic lift, especially near the ground. This enables higher speeds if the weight of the vehicle is increasingly carried by air instead of water. With the device in the form of a delta-shaped inflatable mat, it is also possible to make significantly more and higher jumps than previously with sail boards, because the sail board, in conjunction with the inflatable mat, acts as an aerodynamic aerofoil.

Insbesondere kann am Umfang der aufblasbaren Matte teil­weise ein Schlauch umlaufen, der zwei Schenkel aufweist, die die vordere Profilkante der Deltafläche bilden.

This facilitates the production of the mat in the form of a delta surface. Furthermore, tubes extending in the longitudinal direction of the delta surface are arranged between the legs of the tube.

Vorzugsweise ist ferner dafür gesorgt, daß die Schläuche Schlauchkammern bilden, die durch Stege getrennt sind, die als aerodynamische Profile geschnitten sind, so daß Längsschnitte durch die aufblasbare Matte aerodynamisch tragende Profile ergeben. Dies erzeugt zusätzlich aerody­namischen Auftrieb.It is also preferably ensured that the tubes form tube chambers which are separated by webs which are cut as aerodynamic profiles, so that longitudinal cuts through the inflatable mat result in aerodynamically supporting profiles. This also creates aerodynamic lift.

Die aufblasbare Matte kann aus luftdichtem Material ge­klebt oder geschweißt sein. Bei dieser Ausbildung ist sie in größeren Stückzahlen auf einfache Weise herstellbar.The inflatable mat can be glued or welded from airtight material. With this design, it can be easily produced in large numbers.

Alternativ kann die aufblasbare Matte aus Segeltuch oder aus mit PVC beschichtetem Material genähte Kammern auf­weisen, in denen aufblasbare Schlauchkörper angeordnet sind. Dies ergibt eine höhere Sicherheit gegen ein Entwei­chen der Luft bei Beschädigung der Kammern durch scharfe Kanten oder dergleichen.Alternatively, the inflatable mat made of canvas or made of PVC-sewn material has chambers in which inflatable tube bodies are arranged. This results in a higher security against escape of air if the chambers are damaged by sharp edges or the like.

Ferner weisen die Schläuche der Matte obere und untere Bogenabschnitte auf, wobei die oberen, gegebenenfalls auch die unteren Bogenabschnitte, durch eine Auflage oder Umhüllung aus flexiblem Material miteinander verbun­den werden. Dadurch erhält die Matte eine glattere Ober- und gegebenenfalls auch Unterseite sowie eine höhere Formsteifigkeit.Furthermore, the hoses of the mat have upper and lower curved sections, the upper, possibly also the lower curved sections, being connected to one another by a support or sheathing made of flexible material. This gives the mat a smoother top and possibly also underside as well as a higher level of dimensional stability.

Die aufblasbare Matte kann Laschen oder Ösen zum Verstagen eines Segelriggs aufweisen. Dadurch kann das Segelrigg wahlweise verstagt oder nicht verstagt werden.The inflatable mat can have tabs or eyelets to support a sailing rig. As a result, the sailing rig can either be staged or not.

Gewünschtenfalls kann am Heck der aufblasbaren Matte ein Halter für ein Ruder oder einen Motor vorgesehen sein. Dies erleichtert das Steuern bzw. ermöglicht einen maschi­nellen Antrieb.If desired, a holder for an oar or a motor can be provided at the rear of the inflatable mat. This facilitates control or enables mechanical drive.

Sodann kann in der Tasche der Matte ein Segelbrett mit lenkbarer Finne angeordnet sein. Dies erleichtert eben­falls das Steuern und erhöht die Richtungsstabilität.Then a sail board with steerable fin can be arranged in the pocket of the mat. This also makes steering easier and increases directional stability.

Um die Bequemlichkeit auf der Matte zu erhöhen, kann sie Vorrichtungen zum lösbaren Befestigen aufblasbarer Schläuche als Körperstütze oder Spritzschutz aufweisen.To increase comfort on the mat, it can have devices for releasably attaching inflatable tubes as body support or splash guard.

Ferner kann der Motor einen in der Luft drehenden Propel­ler antreiben. Dadurch kann ein mit der Vorrichtung ver­sehenes Segelbrett ohne Segel angetrieben werden.The engine can also drive a propeller rotating in the air. As a result, a sail board provided with the device can be driven without a sail.

Sodann kann die Matte den Antrieb und eine Tragfläche eines Ultraleichtflugzeugs tragen. Dies ermöglicht das Fliegen sowie Starten und Landen auf dem Wasser mit einem die Vorrichtung aufweisenden Segelbrett (ohne Segelrigg).The mat can then carry the drive and a wing of an ultralight aircraft. This enables flying as well as take-off and landing on the water with a sail board having the device (without a sailing rig).

Die Erfindung und ihre Weiterbildungen werden nachstehend anhand schematischer Zeichnungen von Ausführungsbeispie­len beschrieben. Es zeigen:

  • Fig. 1 perspektivisch die Unterseite eines Segelbretts mit einer daran angebrachten Vorrichtung,
  • Fig. 2 eine Draufsicht auf die Vorrichtung nach Fig. 1,
  • Fig. 3 den Längsschnitt III-III nach Fig. 2,
  • Fig. 4 den Querschnitt IV-IV nach Fig. 2, jedoch zusätz­lich mit verstagtem Segelmast und Auflage, und
  • Fig. 5 die Vorrichtung nach Fig. 1 mit Propellerantrieb und Deltatragfläche.
The invention and its developments are described below with the aid of schematic drawings of exemplary embodiments. Show it:
  • 1 is a perspective view of the underside of a sailing board with an attached device,
  • 2 is a plan view of the device of FIG. 1,
  • 3 shows the longitudinal section III-III according to FIG. 2,
  • Fig. 4 shows the cross section IV-IV of FIG. 2, but additionally with a stilted mast and pad, and
  • Fig. 5 shows the device of FIG. 1 with propeller drive and delta wing.

Der Schiffskörper nach Fig. 1 besteht aus einem Segelbrett 1 und einer Vorrichtung in Form einer aufblasbaren Matte 2 mit einer nach hinten offenen Tasche 3 am Vorderteil ihrer Unterseite. Das Segelbrett 1 ist teilweise in die Tasche 3 eingeführt und darin durch den Innendruck der aufgeblasenen Matte 2 festgeklemmt. Die Breite der Matte 2 ist größer als die des Segelbretts 1. Vorzugsweise ist die Matte 2 etwa dreimal so breit wie das Segelbrett 1. Die Tasche 3 erstreckt sich vom vorderen Teil der Matte 2 bis in die Nähe des Schwertkastens mit einem ausklappbaren Schwert 4. Das Schwert 4 kann daher auch nach Einführung des Segelbretts 1 in die Tasche 3 ausge­klappt werden.1 consists of a sail board 1 and a device in the form of an inflatable mat 2 with a pocket 3 open at the rear on the front part of its underside. The sail board 1 is partially inserted into the pocket 3 and clamped therein by the internal pressure of the inflated mat 2. The width of the mat 2 is greater than that of the sailing board 1. The mat 2 is preferably about three times as wide as the sailing board 1. The pocket 3 extends from the front part of the mat 2 to the vicinity of the sword case with a foldable sword 4. The sword 4 can therefore be folded out into the pocket 3 even after the introduction of the sailing board 1.

Um zusätzlich ein Verrutschen des Segelbretts 1 in der Tasche 3 zu vehindern, können im Heckteil zusätzliche Verbindungsmittel 5 zwischen Segelbrett 1 und Matte 2 vorgesehen sein. Vorteilhafterweise werden zu diesem Zweck Gurte durch (nicht dargestellte) Fußschlaufen des Segelbretts 1 geführt und um das Heckteil der Matte ge­schlungen. Auf diese Weise ist sichergestellt, daß das unveränderte Heckteil des Segelbretts 1 Wasserberührung hat.In order to additionally prevent the sailing board 1 from slipping in the pocket 3, additional connecting means 5 can be provided in the rear part between the sailing board 1 and the mat 2. For this purpose, straps are advantageously passed through (not shown) foot straps of the sailing board 1 and wrapped around the rear part of the mat. In this way it is ensured that the unchanged rear part of the sailing board has 1 water contact.

Wie Fig. 2 zeigt, hat die Matte 2 mit ihrer Längsmittel­achse zusammenfallende langgestreckte Aussparungen 6 und 7, von denen die Aussparung 6 zur Durchführung eines in Längsrichtung bzw. Fahrtrichtung verstellbaren Mastes 8 und die Aussparung 7 zur Durchführung des Schwertes 4 des Segelbretts 1 dient. In der Draufsicht hat die Matte 2 die Form einer Deltafläche mit vorwärts gepfeilter Hinterkante. Am Umfang der Matte 2 läuft teilweise ein Schlauch 9 um, der der Matte die vordere Profilkante der Deltafläche verleiht. Zwischen den Schenkeln des Schlauches 9 sind sich in Längsrichtung erstreckende Schläuche 10 bis 12 angeordnet, deren Länge von den äuße­ren Schläuchen 10 zu den mittleren Schläuchen 12 zunimmt.As shown in FIG. 2, the mat 2 has elongated recesses 6 and 7 which coincide with its longitudinal central axis, of which the recess 6 is used to carry out a mast 8 which is adjustable in the longitudinal direction or the direction of travel and the recess 7 is used to carry the sword 4 of the sailing board 1. In the top view, the mat 2 has the shape of a delta surface with the rear edge swept forward. A hose 9 runs around the circumference of the mat 2, which gives the mat the front profile edge of the delta surface. Between the legs of the hose 9 there are hoses 10 to 12 extending in the longitudinal direction, the length of which increases from the outer hoses 10 to the middle hoses 12.

Die einzelnen Schlauchkammern der Matte 2 sind nach Fig. 3 durch Stege 13 getrennt, die als aerodynamische Profile geschnitten sind, so daß Längsschnitte durch die Matte 2 aerodynamisch tragende Profile ergeben.The individual hose chambers of the mat 2 are separated according to FIG. 3 by webs 13, which are cut as aerodynamic profiles, so that longitudinal cuts through the mat 2 result in aerodynamically supporting profiles.

Die Matte 2 kann in herkömmlicher Weise, wie es sich bei Luftmatratzen, Schlauchbooten oder sonstigen aufblas­baren Bootskörpern bewährt hat, aus luftdichtem Material geklebt oder geschweißt sein. Es ist aber auch möglich, daß die aufblasbare Matte 2 aus Segeltuch oder aus mit PVC beschichtetem Material genähte Kammern aufweist, in denen (nicht dargestellte) aufblasbare Schläuche angeord­net sind.The mat 2 can be glued or welded from airtight material in a conventional manner, as has proven itself in air mattresses, inflatable boats or other inflatable hulls. However, it is also possible for the inflatable mat 2 to have chambers sewn from canvas or from PVC-coated material, in which (not shown) inflatable tubes are arranged.

Bei der Abwandlung nach Fig. 4 ist die Matte 2 mit einer Auflage 14 oder einer Umhüllung aus flexiblem Material versehen, die die oberen bzw. gegebenenfalls auch die un­teren Bogenabschnitte der Schläuche der Matte 2 mitein­ander verbindet. Dies ergibt zum einen eine glattere Ober­seite bzw. gegebenenfalls auch Unterseite der Matte 2, und zum anderen wird auch die Formsteifigkeit der Matte 2 wesentlich erhöht.In the modification according to FIG. 4, the mat 2 is provided with a support 14 or a covering made of flexible material, which connects the upper or possibly also the lower arc sections of the tubes of the mat 2 to one another. On the one hand, this results in a smoother top side or possibly also underside of the mat 2, and on the other hand the stiffness of the mat 2 is also significantly increased.

An der Matte 2 können, wie es ebenfalls in Fig. 4 darge­stellt ist, Laschen oder Ösen 15 angenäht sein, so daß der Schiffskörper wahlweise mit einem verstagten oder einem unverstagten Segelrigg gefahren werden kann. Vorteilhaf­terweise sind die Laschen so angenäht, daß die Krängungs­kräfte des Mastes 8 über die Tasche 3 auf das Segelbrett 1 übertragen werden.On the mat 2, as is also shown in FIG. 4, tabs or eyelets 15 can be sewn on, so that the hull can be driven either with an open-ended or an unpayed sailing rig. Advantageously, the tabs are sewn on so that the heeling forces of the mast 8 are transmitted to the sailboard 1 via the pocket 3.

Am Heck der Matte 2 kann ein (nicht dargestellter) Halter für ein Ruder oder einen Motor 17 vorgesehen sein, wie sie z.B. bei Schlauchbooten vorgesehen sind. Vorteilhaft ist es auch, wenn eine am Segelbrett 1 angebrachte Finne 16 (Fig. 1) lenkbar ist.At the rear of the mat 2, a holder (not shown) for an oar or a motor 17 can be provided, as is e.g. are provided for inflatable boats. It is also advantageous if a fin 16 (FIG. 1) attached to the sailing board 1 can be steered.

Wenn der Schiffskörper zum bequemen Segeln mit verstagtem Rigg verwendet werden soll, ist es vorteilhaft, die Matte 2 schlauchbootartig mit zusätzlichen aufblasbaren Schläu­chen als Körperstütze oder Spritzschutz zu versehen, die sich lösbar befestigen lassen.If the hull is to be used for comfortable sailing with a rigged rig, it is advantageous to provide the mat 2 as an inflatable boat with additional inflatable hoses as body support or splash protection, which can be detachably attached.

Ferner kann der Schiffskörper in herkömmlicher Weise durch einen im Wasser drehenden, motorgetriebenen Propel­ler angetrieben werden.Furthermore, the hull can be driven in a conventional manner by a motor-driven propeller rotating in the water.

So wird der Schiffskörper nach Fig. 5 durch einen auf der Matte 2 gelagerten Motor 17 über einen in der Luft drehen­den Propeller 18 angetrieben. Zusätzlich kann auf der Mat­te 2 auf einem Gestell 19, wie es bei schwerkraftgesteuer­ ten Ultraleichtflugzeugen üblich ist, eine Tragfläche in Deltaform angeordnet sein, so daß die gesamte Anord­nung als Flugboot dienen kann, bei dem der aus Segel­brett 1 und Matte 2 gebildete Schwimmkörper als Schwimmer dient.5 is driven by a motor 17 mounted on the mat 2 via a propeller 18 rotating in the air. In addition, on the mat 2 on a frame 19, as is the case with gravity control ten ultralight aircraft is customary, a wing can be arranged in delta form, so that the entire arrangement can serve as a flying boat, in which the floating body formed from sailing board 1 and mat 2 serves as a float.

Mit 21 ist hier der Fahrersitz angedeutet. Dieses Flug­boot ist in ähnlicher Weise wie ein Ultraleichtflugzeug flugfähig.The driver's seat is indicated at 21 here. This flying boat is able to fly in a similar way to an ultralight aircraft.
