Description

Die Erfindung bezieht sich auf eine Startschot für Windsurfer.The invention relates to a starting sheet for windsurfers.

Die bisher verwendeten Startschoten für Windsurfer bestehen aus einer dicken Schot, die am vorderen Gabelbaumende befestigt ist, und die bis etwa zum Mastfuss reicht. Die Startschot hängt lose nach unten oder wird mit einer elastischen Schot, die im untersten Drittel in die Startschot eingeknüpft und mit dem Mastfuss verbunden ist, gestrafft.The starting sheets used so far for windsurfers consist of a thick sheet attached to the front end of the boom, which extends to about the mast base. The starting sheet hangs loosely downwards or is tightened with an elastic sheet that is tied into the lower third in the starting sheet and is connected to the mast foot.

Diese Startschoten haben den grossen Nachteil, dass es damit grosse und manchmal äusserste Kraftanstrengung erfordert, das im Wasser liegende Rigg in die Segelstellung zu ziehen. Schwierigkeiten, das Rigg aufzuziehen haben nicht nur Anfänger und weniger kräftige Sportler, sondern durchaus auch Könner, und zwar insbesondere bei hohen Windstärken.The main disadvantage of these launch sheets is that it requires great and sometimes extreme effort to pull the rig lying in the water into the sail position. Difficulties in pulling up the rig are not only for beginners and less powerful athletes, but also for experts, especially when the wind is strong.

Aufgabe der Erfindung ist die Schaffung einer Startschot für Windsurfer, die es gestattet, das Rigg leichter, d.h. mit weniger Kraft, in die Segelstellung zu bringen.The object of the invention is to provide a starting sheet for windsurfers which allows the rig to be lighter, i.e. with less power to feather.

Der Erfindung liegt die Erkenntnis zugrunde, dass diese Aufgabe durch eine Startschot gelöst werden kann, wenn ein Ende derselben oberhalb des Gabelbaumes am Mast angreift.The invention is based on the knowledge that this object can be achieved by a starting sheet if one end of the same attacks above the boom on the mast.

Gegenstand der Erfindung ist eine Startschot für Windsurfer, wobei eines der Enden der Schot am vorderen Gabelbaumende angreift, die dadurch gekennzeichnet ist, dass das andere Ende der Schot am Mast oberhalb des Gabelbaumes angreift.The invention relates to a starting sheet for windsurfers, one of the ends of the sheet engaging the front boom end, which is characterized in that the other end of the sheet engages the mast above the boom.

Vorteilhafterweise ist eine zweite Schot vorgesehen, die an der ersten Schot angreift.A second sheet is advantageously provided which engages the first sheet.

Die erste und/oder die zweite Schot bestehen vorzugsweise ganz oder teilweise aus elastischem Material.The first and / or the second sheet preferably consist entirely or partially of elastic material.

Besonders günstige Kräfteverhältnisse werden erreicht, wenn ein Ende der Schot im Bereich der Mastspitze angreift.Particularly favorable power relationships are achieved when one end of the sheet engages in the area of the mast tip.

Die Schot soll länger sein als der Abstand zwischen ihren Befestigungspunkten.The sheet should be longer than the distance between its attachment points.

Die erfindungsgemässe Schot gestattet es, das Rigg mit erheblich vermindertem Kraftaufwand aus dem Wasser in Segelstellung zu ziehen. Dies beruht zum einen darauf, dass wenn die Schot oberhalb des Gabelbaumes am Mast angreift, ein längerer Hebelarm gegeben ist, der eine erhebliche Kraftverminderung zur Folge hat. Zum anderen beruht der verringerte Kraftaufwand jedoch auf der Anatomie des menschlichen Körpers. In aufrechter Stellung kann der Surfer nur mit verhältnismässig wenig Kraft angreifen. Er kann hingegen, wenn er in die Hocke geht, mit erheblich mehr Kraft ziehen. Andererseits ist die Kraft, die notwendig ist, um das Rigg aus dem Wasser zu ziehen bei einem tieferen Angriffspunkt der Zugkraft bedeutend grösser als bei einem höheren Angriffspunkt der Zugkraft. Durch die Kraftersparnis aufgrund des verlängerten Hebelarmes ist es dem Surfer möglich, in aufrechterem Zustand das Rigg heranzuziehen und da bei einem solchen höheren Angriffspunkt eine geringere Zugkraft erforderlich ist, führt dies dazu, dass eine weitere Verringerung der zum Herausziehen notwendigen Kraft eintritt.The sheet according to the invention allows the rig to be pulled out of the water into the sail position with considerably less effort. On the one hand, this is due to the fact that when the sheet attacks the mast above the boom, there is a longer lever arm, which results in a considerable reduction in power. On the other hand, the reduced effort is based on the anatomy of the human body. In an upright position, the surfer can only attack with relatively little force. However, when he crouches, he can pull with considerably more force. On the other hand, the force required to pull the rig out of the water is significantly greater with a lower point of application of the tractive force than with a higher point of application of the tractive force. The power saving due to the extended lever arm enables the surfer to pull up the rig in an upright state and since a lower pulling force is required at such a higher point of attack, this leads to a further reduction in the force required for pulling out.

Bei der erfindungsgemässen Schot ist es zur erläuterten Kraftersparnis wesentlich, dass ein Ende derselben oberhalb des Gabelbaumes, und zwar möglichst hoch, angreift. Andererseits muss das andere Ende im Bereich des Gabelbaumes angreifen, denn es muss sichergestellt sein, dass der Surfer beim Herausziehen des Riggs aus dem Wasser schliesslich ohne Schwierigkeiten auf den Gabelbaum übergreifen kann. Vorteilhafterweise ist die Schot natürlich so ausgestaltet, dass sie bei im Wasser liegendem Rigg leicht ergriffen werden kann.In the sheet according to the invention, it is essential for the energy saving to be explained that one end of the sheet attacks above the boom, and as high as possible. On the other hand, the other end must attack in the area of the boom, because it must be ensured that the surfer can finally reach the boom without difficulty when pulling the rig out of the water. Of course, the sheet is advantageously designed in such a way that it can be easily gripped with a rig lying in the water.

Die Erfindung wird nachstehend anhand der Zeichnung näher erläutert. Es zeigen:

  • Fig. 1 eine schematische Ansicht eines Windsurfers in Vorderansicht mit der erfindungsgemässen Schot in Zugstellung und
  • Fig. 2 eine schematische Ansicht eines Windsurfers in Seitenansicht mit der erfindungsgemässen Schot in Ruhestellung.
  • Fig. 1 zeigt einen Windsurfer, der im wesentlichen aus Brett 12, Mast 3, Gabelbaum 4 und Segel 14 besteht, wobei das aus Mast, Gabelbaum und Segel bestehende Rigg im Wasser liegt.
The invention is explained below with reference to the drawing. Show it:
  • Fig. 1 is a schematic view of a windsurfer in front view with the sheet according to the invention in the pull position and
  • Fig. 2 is a schematic view of a windsurfer in side view with the sheet according to the invention in the rest position.
  • Fig. 1 shows a windsurfer, which consists essentially of board 12, mast 3, boom 4 and sail 14, the rig consisting of mast, boom and sail lying in the water.

Die erfindungsgemässe Schot 1, 2 ist in der anfänglichen Zugstellung gezeigt.The sheet 1, 2 according to the invention is shown in the initial pull position.

Gemäss der hier gezeigten bevorzugten Ausführungsform besteht die Startschot aus einer ersten Schot 1 und einer zweiten Schot 2. Alternativ kommt es in Betracht, die zweite Schot 2 wegzulassen. In diesem Fall muss die Startschot 1 solche Länge aufweisen, dass sie von dem auf dem Brett stehenden Surfer leicht erreicht wird.According to the preferred embodiment shown here, the starting sheet consists of a first sheet 1 and a second sheet 2. Alternatively, it is possible to omit the second sheet 2. In this case, the starting sheet 1 must be of such a length that it can be easily reached by the surfer standing on the board.

Die erste Schot 1 greift mit einem Ende oberhalb des Gabelbaumes 4 am Mast 3 an. Vorzugsweise greift sie im Bereich der Mastspitze 6 bzw. direkt an dieser an.The first sheet 1 engages at one end above the boom 4 on the mast 3. It preferably engages in the area of the mast tip 6 or directly on it.

Das andere Ende der ersten Schot ist am vorderen Gabelbaumende 5 befestigt.The other end of the first sheet is attached to the front boom end 5.

Die Länge der ersten Schot 1 ist i.a. grösser als der Abstand zwischen den Befestigungspunkten. Vorzugsweise ist diese Schot 5-50%, insbesondere 10-30% und vorzugsweise etwa 20% länger als der Abstand zwischen den Befestigungspunkten. Insbesondere ist es vorteilhaft, wenn die erste Schot 1 solche Länge aufweist, dass sich in gespanntem Zustand in der Schot in etwa ein rechter Winkel einstellt, wie dies in der Zeichnung dargestellt ist.The length of the first sheet 1 is generally greater than the distance between the attachment points. This sheet is preferably 5-50%, in particular 10-30% and preferably about 20% longer than the distance between the fastening points. In particular, it is advantageous if the first sheet 1 is of such a length that, when tensioned, the sheet is approximately at a right angle, as shown in the drawing.

Die Befestigung der Schot 1 im Bereich der Mastspitze 6 kann auf verschiedene Weise erfolgen. Beispielsweise kann die Mastspitze geeignete Einrichtungen, wie ein Loch oder einen Ring, aufweisen, woran die Schot befestigt wird. Alternativ können auf der Segelspitze ein Ring, eine Schlaufe, eine Kappe oder Ösen vorgesehen werden, woran die Schot befestigt wird.The sheet 1 can be fastened in the area of the mast tip 6 in various ways. For example, the mast tip can have suitable devices, such as a hole or a ring, to which the sheet is attached. Alternatively, a ring, a loop, a cap or eyelets can be provided on the sail tip, to which the sheet is attached.

Eine besonders vorteilhafte Befestigung der Schot im Bereich der Mastspitze kann über eine Öse im Segel 14 im Bereich der Mastspitze erfolgen. Die Öse kann in üblicher Weise mittels geeigneter Werkzeuge vorgesehen werden. In dem Fall, dass keine Werkzeuge für eine Öse zur Verfügung stehen, können kleine, vorzugsweise dreieckige Kunststoffplatten beidseitig des Segels, die beispielsweise an den Ecken Löcher haben, mittels Schrauben und Muttern befestigt werden. Die Kunststoffplatten weisen auch in der Mitte ein Loch auf. Das Segel wird enstprechend den Löchern der Kunststoffplatten gelocht. Die Schot wird dann über dieses mittlere Loch im Bereich der Mastspitze befestigt, wobei sie direkt durch das Loch geführt werden kann oder eine kurze Schot durch das Loch um die Mastspitze geführt werden kann, an die die Schot, gegebenenfalls lösbar, angreift.A particularly advantageous attachment of the sheet in the area of the mast tip can be carried out via an eyelet in the sail 14 in the area of the mast tip. The eyelet can be provided in the usual way using suitable tools. In the event that no tools are available for an eyelet, small, preferably triangular plastic plates on both sides of the sail, which have holes in the corners, for example, can be fastened by means of screws and nuts. The plastic plates also have a hole in the middle. The sail is perforated according to the holes in the plastic plates. The sheet is then fastened via this middle hole in the area of the mast tip, it being possible to pass it directly through the hole or a short sheet can be passed through the hole around the mast tip, to which the sheet engages, optionally releasably.

Die zweite Schot 2 greift an der ersten Schot 1 an. Vorzugsweise ist die zweite Schot 2 an der ersten Schot 1 verschiebbar angeordnet, beispielsweise ist die zweite Schot an einem Ring befestigt, der auf der ersten Schot läuft. Dies hat den Vorteil, dass beim Herausziehen des Segels die erste Schot 1 über ihre gesamte Länge gespannt ist, so dass von der Schot 2 auf den gespannten Teil 11 der ersten Schot übergegriffen werden kann.The second sheet 2 engages the first sheet 1. The second sheet 2 is preferably slidably arranged on the first sheet 1, for example the second sheet is fastened to a ring which runs on the first sheet. This has the advantage that when the sail is pulled out, the first sheet 1 is stretched over its entire length, so that the sheet 2 can reach over the tensioned part 11 of the first sheet.

Die erste Schot kann in dem Teilstück 10 zwischen oberem Angriffspunkt und dem Angriffspunkt der zweiten Schot 2 aus dünnem Schotmaterial bestehen. Der zwischen Gabelbaum und Angriffspunkt der zweiten Schot liegende Teil der ersten Schot 11 besteht jedoch vorzugsweise aus dickem Schotmaterial, in das Knoten 15 eingeknüpft sind, um die Handhabung zu erleichtern. Die Schot 2 besteht gleichfalls vorzugsweise aus dickem Schotmaterial mit Knoten 15.The first sheet can consist of thin sheet material in the section 10 between the upper point of attack and the point of attack of the second sheet 2. However, the part of the first sheet 11 lying between the boom and the point of application of the second sheet is preferably made of thick sheet material, into which knots 15 are tied in order to facilitate handling. The sheet 2 also preferably consists of thick sheet material with knots 15.

In Fig. 2 ist die erfindungsgemässe Schot in Ruhestellung gezeigt. Durch das Gewicht des Ringes 7 und der zweiten Schot 2 hängt die erste Schot 1 parallel zum Mast 3.2 the sheet according to the invention is shown in the rest position. Due to the weight of the ring 7 and the second sheet 2, the first sheet 1 hangs parallel to the mast 3.

Die zweite Schot 2 hat vorzugsweise solche Länge, dass in Ruhestellung ihr unteres Ende 8 bis etwa zum Mastfuss 9 reicht. In üblicher Weise kann die Schot 2 über ein Gummiband 13 mit dem Mastfuss 9 verbunden werden.The second sheet 2 is preferably of such a length that its lower end 8 extends approximately to the mast foot 9 in the rest position. In the usual way, the sheet 2 can be connected to the mast foot 9 via a rubber band 13.

Gemäss einer alternativen Ausführungsform ist die erste Schot 1 unterteilt und besteht aus einem ersten Teil 10, der mit der zweiten Schot 2 verbunden ist und einem zweiten Teil 11, der auf dem ersten Teil 10 und der zweiten Schot 2 verschiebbar, beispielsweise über einen Ring, angreift.According to an alternative embodiment, the first sheet 1 is divided and consists of a first part 10 which is connected to the second sheet 2 and a second part 11 which is displaceable on the first part 10 and the second sheet 2, for example via a ring, attacks.

Es kommt ferner in Betracht, die Schoten ganz oder teilweise aus elastischem Material auszuführen. Als elastisches Material eignen sich insbesondere Gummischoten und Gummi-Textil-Schoten, wobei letztere eine definierte Streckgrenze haben.It is also possible to make the pods entirely or partially from elastic material. Rubber pods and rubber textile pods are particularly suitable as the elastic material, the latter having a defined yield strength.

Durch Verwendung elastischen Schotmaterials wird ein andersartiges Zugverhalten erzielt sowie erreicht, dass die Schoten in Ruhestellung mastparallel gespannt sind.By using elastic sheet material, a different type of tensile behavior is achieved and the sheets are tensioned parallel to the mast in the rest position.

Beispielsweise kann der Teil 10 der Schot 1 und/oder der Teil 11 der Schot 1 aus elastischem Material bestehen. Der Teil 11 der Schot besteht vorzugsweise aus dickerem elastischem Schotmaterial. Auch die Schot 2 kann aus solchem elastischem Material bestehen.For example, part 10 of sheet 1 and / or part 11 of sheet 1 may consist of elastic material. The part 11 of the sheet is preferably made of thicker elastic sheet material. The sheet 2 can also consist of such an elastic material.

Es versteht sich, dass auch der zweite Teil 11 der ersten Schot 1 mit der Schot 2 eine integrale durchgehende Schot bilden können, an die der erste Teil 10 der ersten Schot 1 in geeignetem Abstand vom Gabelbaumende angreift.It goes without saying that the second part 11 of the first sheet 1 can also form an integral continuous sheet with the sheet 2, to which the first part 10 of the first sheet 1 engages at a suitable distance from the end of the boom.

Es versteht sich, dass die erfindungsgemässe Startschot, die hier im Hinblick auf einen üblichen Windsurfer beschrieben ist, nicht darauf beschränkt ist. So sind beispielsweise Surfer bekannt, die anstelle eines Gabelbaumes einen Grossbaum oder eine Halteschot haben. In diesem Fall wird ein Ende der erfindungsgemässen Schot am Mast oder am Grossbaum in deren Verbindungsbereich befestigt.It goes without saying that the starting sheet according to the invention, which is described here with regard to a conventional windsurfer, is not restricted to this. For example, surfers are known who have a large boom or a holding sheet instead of a boom. In this case, one end of the sheet according to the invention is fastened to the mast or to the large boom in its connecting area.
