Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a device according to the preamble of claim 1.

Üblicherweise ist eine Trapezleine zum Einhängen eines Hakens eines vom Surfer getragenen Trapezgurts beidends mit dem Gabelbaum fest verbunden. Dies führt dazu, daß bei zu hohem Segeldruck der über die Trapezleine fest am Gabelbaum hängende Surfer zusammen mit dem umschlagenden Rigg mitgerissen wird, falls es ihm nicht gelingt, rechtzeitig die Trapezleine aus dem Haken des Trapezgurtes auszuhängen.Usually a trapezoid line for hooking a hook of a harness worn by the surfer is firmly connected to the boom at both ends. This means that if the sail pressure is too high, the surfer hanging on the boom with the trapezoid line is carried along with the folding rig if he does not succeed in unhooking the trapezoid line from the hook of the harness belt in good time.

Um diese Schwierigkeiten auszuschließen, sind bereits sogenannte Auslösehaken am Trapezgurt vorgeschlagen worden, die bei Überschreiten eines vorgegebenen Zugs auslösen und somit die Verbindung zwischen dem Trapezgurt und der Trapezleine am Gabelbaum aufheben. Diese Auslösehaken haben sich jedoch in der Praxis nicht bewährt, da sie stets bei einem vorgegebenen Zug auslösen und dabei entweder die Gefahr besteht, daß das Auslösen zu früh erfolgt, obgleich der Surfer durchaus den Druck noch abfangen kann, oder aber daß das Auslösen zu spät erfolgt und damit die Sicherungsfunktion völlig verloren geht. Nachdem die Auslösefunktion ja gerade bei kurzen, starken Böen bedeutsam ist und je nach körperlicher Verfassung des Surfers ein Abfangen solcher Druckstöße in sehr unterschiedlicher Höhe möglich ist, führt eine solche automatische bei einer bestimmten Auslösekraft erfolgende Aufhebung der Verbindung zwischen Trapezgurt und Trapezleine über einen Trapez-Auslösehaken nur zu unbefriedigenden Ergebnissen.In order to rule out these difficulties, so-called release hooks on the trapezoidal belt have already been proposed, which release when a predetermined tension is exceeded and thus break the connection between the trapezoidal belt and the trapezoidal line on the boom. However, these release hooks have not proven themselves in practice, since they always release on a given move and there is either the risk that the release occurs too early, although the surfer can still intercept the pressure, or that the release is too late takes place and the security function is completely lost. Since the release function is particularly important in the case of short, strong gusts and, depending on the physical condition of the surfer, such pressure surges can be intercepted at very different heights, such an automatic release of the connection between the harness belt and the harness line takes place via a harness with a certain release force. Trigger hook only to unsatisfactory results.

Darüber hinaus ist auch bereits eine weitere Ausklinkvorrichtung, der sogenannte Charchulla-Gurt bekannt geworden, bei welchem eine mit einem Hüftgurt des Surfers verbundene Leine mit einem Knoten in eine Ausnehmung eines auf dem Gabelbaum verschiebbaren Schlittens eingehängt wird, während der Surfer das hinter dem Schlitten verlaufende freie Ende der Leine zwischen Segelhand und Gabelbaum hält. Bei zu hohem Segeldruck soll der Surfer das Ende der Leine nach oben aus dem Schlitten herausreißen und damit die Verbindung lösen. Diese Anordnung hat aber wiederum den Nachteil, daß zum einen infolge der hohen Haltekraft der Leine in dem Schlitten ein solches Herausreißen sehr schwierig ist und zum anderen der Surfer das Ende der Leine nicht in der Segelhand halten kann, da er sich ansonsten mit dieser nicht am Gabelbaum festhalten kann. Er muß also die Leine erst unter Lösung des Griffs vom Gabelbaum zu fassen versuchen, was aber in den geschilderten Extremsituationen nahezu nie stattfinden kann, da dann der zu vermeidende gefährliche Schleudersturz bereits stattgefunden hat.In addition, a further notching device, the so-called Charchulla belt, has also become known, in which a line connected to a hip belt of the surfer is hung with a knot in a recess of a sled that can be moved on the boom, while the surfer runs the one behind the sled holds the free end of the line between the sailing hand and boom. If the sail pressure is too high, the surfer should pull the end of the line up out of the sled and thus loosen the connection. This arrangement has again the disadvantage that, on the one hand, due to the high holding force of the line in the sled, pulling it out is very difficult and, on the other hand, the surfer cannot hold the end of the line in the sailing hand, since otherwise he would not hold onto the boom with it can. He must therefore first try to take the line by loosening the handle from the boom, but this can almost never take place in the extreme situations described, since then the dangerous spin fall to be avoided has already taken place.

Die bisher übliche Lösung der Trapezleine aus dem Haken durch zum Körperziehen des Gabelbaums, wodurch die Trapezleine aus dem Haken herausfallen soll, wird bei starkem Wind nur von sehr wenigen Surfern beherrscht, da der Zug des Segels und des Gabelbaums immer vom Körper weggerichtet ist und damit in den meisten Fällen ein solches Auslösen der Trapezleine unmöglich ist.The previously common solution of the trapeze line from the hook to pulling the body of the boom, causing the trapeze line to fall out of the hook, is only mastered by very few surfers in strong winds, since the pull of the sail and boom is always directed away from the body and thus in most cases such a release of the trapezoid line is impossible.

Weiterhin ist das Lösen der Trapezleine vom Haken in vielen Fällen an sich nicht wünschenswert, wenn nämlich das Rigg nur stärker krängt, der Surfer es an sich aber noch halten kann. In einem solchen Fall wird er durch die starre Geometrie zwischen dem an seinem Trapezgurt angebrachten Haken und dem Gabelbaum in eine Stellung über dem Surfbrett gezogen, aus der er nach Lee in das Segel stürzt.Furthermore, the detachment of the trapeze line from the hook is not desirable in many cases, namely if the rig only heels more, but the surfer can still hold it. In such a case, the rigid geometry between the hook attached to his harness and the boom will pull him into a position above the surfboard from which he will plunge into the sail after Lee.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der gattungsgemäßen Art zu schaffen, die eine optimale Lage des Surfers zum Gabelbaum und eine sichere Lösung des Surfers vom Gabelbaum in Extremsituationen ermöglicht.The invention is therefore based on the object of creating a device of the generic type which enables an optimal position of the surfer relative to the boom and a safe solution of the surfer from the boom in extreme situations.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale im Kennzeichnungsteil des Anspruches 1 gelöst. Durch die erfindungsgemäße Ausgestaltung wird erreicht, daß beim Lösen der Segelhand vom Gabelbaum und damit vom Betätigungsgriff der Klemmvorrichtung selbsttätig die Verbindung zwischen Trapezleine und Gabelbaum aufgehoben wird. Wenn also dem Surfer durch eine Windböe der Gabelbaum aus der Segelhand geschlagen wird, führt dies nicht zu einem Schleudersturz des Surfers nach Lee. Wenn der Surfer aufgrund ständig zunehmenden Winddrucks das Rigg nicht mehr halten kann, dann kann er gleichermaßen durch Loslassen des Betätigungsgriffs die Klemmvorrichtung lösen und damit den Abstand des Hakens seines Trapezgurtes zum Gabelbaum vergrößern. Er wird also nicht nach Lee über das Surfbrett gezogen, sondern kann weiter nach Luv trimmen. Nach einer solchen Verlängerung der Trapezleine durch Herausziehen eines Teils von ihr durch die Klemmvorrichtung muß dann gegebenenfalls die Klemmvorrichtung wieder geschlossen werden.This object is achieved by the features in the characterizing part of claim 1. The configuration according to the invention ensures that when the sail hand is released from the boom and thus from the actuating handle of the clamping device, the connection between the trapezoid line and the boom is broken. So if the surfer is knocked out of the sails hand by a gust of wind, this does not result in the surfer falling to Lee. If the surfer can no longer hold the rig due to constantly increasing wind pressure, he can also release the clamping device by releasing the operating handle and thus increase the distance between the hook of his harness and the boom. So it is not dragged over the surfboard after Lee, but can continue to trim upwind. After such an extension of the trapezoid line by pulling a part of it out through the clamping device, the clamping device may then have to be closed again.

Durch die Maßnahmen nach Anspruch 2 wird zum einen erreicht, daß die Trapezleine nach einem Lösen der Klemmung durch Loslassen des Betätigungsgriffs nicht wieder in die Klemmvorrichtung eingefädelt werden muß, sondern selbsttätig zurückgezogen wird. Zum anderen wird hierdurch insbesondere die angesprochene Verlängerbarkeit der Trapezleine, d.h. die Abstandsveränderung zwischen dem Haken des Trapezgurtes des Surfers und dem Gabelbaum in einfacher Weise unterstützt, da nicht nur Verlängerungen sondern auch Verkürzungen in einfacher Weise möglich sind.By the measures according to claim 2 it is achieved on the one hand that the trapezoidal line does not have to be threaded back into the clamping device after releasing the clamping by releasing the actuating handle, but is automatically retracted. On the other hand, this specifically affects the extendability of the trapeze line, i.e. supports the change in distance between the hook of the surfer's harness and the boom in a simple manner, since not only extensions but also shortenings are possible in a simple manner.

Die Ansprüche 3 und 4 geben besonders vorteilhafte Ausgestaltungen für die elastische Verlängerbarkeit und VerkUrzbarkeit der Trapezleine wieder.Claims 3 and 4 represent particularly advantageous configurations for the elastic extensibility and shortenability of the trapezoid line.

Der Anspruch 5 gibt eine besonders günstige konstruktive Lösung für die Klemmvorrichtung an.Claim 5 specifies a particularly favorable constructive solution for the clamping device.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Auführungsbeispiels anhand der Zeichnung. Es zeigt

  • Fig. 1 eine Aufsicht auf einen Surfer mit einem Horizontalschnitt durch ein Rigg, wobei ein Surfbrett selbst nur schematisch angedeutet ist,
  • Fig. 2 eine vergrößerte Seitenansicht einer Klemmvorrichtung an einem Gabelbaum, und
  • Fig. 3 eine Seitenansicht einer weiteren AusfUhrungsform einer Klemmvorrichtung in teilweise aufgebrochener Darstellung.
Further advantages, features and details of the invention result from the following description of an exemplary embodiment with reference to the drawing. It shows
  • 1 is a top view of a surfer with a horizontal section through a rig, a surfboard itself being only indicated schematically,
  • Fig. 2 is an enlarged side view of a clamping device on a boom, and
  • 3 shows a side view of a further embodiment of a clamping device in a partially broken-open representation.

In Fig. 1 erkennt man ein nur schematisch abgebrochen dargestelltes Surfbrett 1, einen kardanisch verschwenkbar mit seinem Mastfuß am Surfbrett 1 befestigten Mast 2 und einen am Mast 2 befestigten Gabelbaum 3 mit einem Segel 4. Der schematisch in Fig. 1 angedeutete Surfer 5 trägt einen Trapezgurt 6 mit einem nach unten offenen Haken 7 in den eine Trapezleine 8 eingehängt ist, die an einem Ende 9 fest mit dem Gabelbaum 3 verbunden ist, während das andere Ende lo der Trapezleine 8 eine am Gabelbaum 3 befestigte Klemmvorrichtung 11 durchsetzt. Eine Trapezleine 8 und eine zugehörige Klemmvorrichtung 11 sind jeweils auf beiden Seiten des Gabelbaums 3 angeordnet, da der Surfer 5 je nach Segel- und Windrichtung wahlweise die Stellung auf dem Surfbrett 1 vertauschen muß.1 shows a surfboard 1, shown only schematically broken off, a gimbal pivotably attached mast 2 to surfboard 1 with its mast foot and a boom 3 attached to mast 2 with a sail 4. Surfer 5, indicated schematically in FIG. 1, wears one Trapezoidal belt 6 with a downwardly open hook 7 in which a trapezoid line 8 is suspended, which is firmly connected at one end 9 to the boom 3, while the other end 10 of the trapeze line 8 passes through a clamping device 11 fastened to the boom 3. A trapezoidal line 8 and an associated clamping device 11 are arranged on both sides of the boom 3, since the surfer 5 must swap the position on the surfboard 1 depending on the sailing and wind direction.

Die Klemmvorrichtung 11 besteht bei dem in den Fig. 1 bis 3 dargestellten Ausführungsbeispiel aus einer auf den Gabelbaum 3 aufgeklemmten Hülse 12, an welcher ein zweiarmiger Klemmhebel 13 schwenkbar gelagert ist, dessen kurzer Arm eine Klemmbacke 14, die die Trapezleine 8 gegen ein an der Hülse 12 befestigten Widerlager 15 verklemmt, wenn der als Betätigungegriff 16 dienende zweite lange Arm des Klemmhebels 13 durch Schließen der Segelhand 17 des Surfers 5, die gleichzeitig den Gabelbaum 3 umgreift zu letzterem hin verschwenkt wird. Bei zu hohem Winddruck, d.h. wenn der Surfer das Rigg nicht mehr halten kann, löst er die Segelhand 17 vom Gabelbaum 3, wodurch die Verklemmung der Trapezleine 8 aufgehoben wird und diese somit unter dem Widerlager 15 durchrutschen kann. Dadurch kann beim Fieren des Segels 4 mit Gabelbaum 3 und auch beim Umschlagen des Riggs die Trapezleine 8 ohne gesondertes Lösen der Verbindung zum Trapezgurt 6 den Surfer 5 nicht in einem sogenannten Schleudersturz mitreißen.The clamping device 11 consists in the embodiment shown in Figs. 1 to 3 of a clamped on the boom 3 sleeve 12, on which a two-armed clamping lever 13 is pivotally mounted, the short arm of a jaw 14, which the trapezoidal line 8 against one of the Sleeve 12 attached abutment 15 jammed when the second long arm of the clamping lever 13 serving as the operating handle 16 is pivoted by closing the sail hand 17 of the surfer 5, which simultaneously engages around the boom 3 toward the latter. If the wind pressure is too high, i.e. if the surfer can no longer hold the rig, he releases the sail hand 17 from the boom 3, which releases the jamming of the trapezoid line 8 and can thus slip under the abutment 15. As a result, when the sail 4 is secured with the boom 3 and also when the rig is turned over, the trapeze line 8 cannot pull the surfer 5 away in a so-called whiplash without separately loosening the connection to the harness 6.

Das freie Ende lo der Trapezleine 8 ist mit einer als Gummizug ausgebildeten elastischen Leine 18 verbunden. Diese ist zu dem dem Mast 2 entfernten Ende des Gabelbaums 3 geführt, wo sie Uber eine Seilrolle 19 umgelenkt wird und an der geganüberliegenden Seite des Gabelbaums 3 bei 2o befestigt ist. Die elastische Leine 18 ermöglicht eine federelastische Verlängerung der Trapezleine 8, so daß beim Loslassen des Betätigungsgriffs 16 des Klemmhebels 13 eine Längenverstellung der Trapezleine 8 in dem Bereich zwischen ihrem einen am Gabelraum 3 befestigten Ende 9 und der Klemmvorrichtung 11 möglich ist. Diese Längenveränderung kann soweit gehen, daß die gleichen Verhältnisse gegeben sind, als wenn das freie Ende 1o der Trapezleine 8 durch die Klemmvorrichtung 11 durchrutscht. Mittels der elastischen Leine 18 wird also auch erreicht, daß anschließend die Trapezleine 8 nicht wieder von Hand in die Klemmvorrichtung 11 eingefädelt werden muß.The free end lo of the trapezoid line 8 is connected to an elastic line 18 designed as an elastic band. This is guided to the end of the boom 3 remote from the mast 2, where it is deflected by a pulley 19 and is fastened to the opposite side of the boom 3 at 20. The elastic line 18 enables a spring-elastic extension of the trapezoid line 8, so that when the actuating handle 16 is released, the clamp lever 13 a length adjustment of the trapezoid line 8 is possible in the area between its one end 9 attached to the fork space 3 and the clamping device 11. This change in length can go so far that the same conditions exist as if the free end 1 o of the trapezoid line 8 slipped through the clamping device 11. By means of the elastic line 18 it is also achieved that the trapezoid line 8 does not then have to be threaded into the clamping device 11 again by hand.

Der Betätigungsgriff 16 des Klemmhebels 13 ist, wie aus Fig. 2 erkennbar ist, als gewölbte, großflächige Platte ausgebildet, deren Wölbung im wesentlichen der des Gabelbaums 3 entspricht, wobei gegebenenfalls zusätzliche Fingervertiefungen 21 vorgesehen sein können, um einerseits einen möglichst guten Griff der Segelhand 17 zu gewährleisten und andererseits zu verhindern, daß sich der Betätigungsgriff 16 in die Segelhand 17 einschneiden kann. Zum Widerlager 15 hin ist diese Platte mit einem. Einschnitt versehen, so daß zwei den Klemmarm 14 bildende Gabelarme entstehen, die beidseits der Hülse 12 auf einer Lagerachse 22 verschwenkbar sind.The actuating handle 16 of the clamping lever 13 is, as can be seen from FIG. 2, designed as a curved, large-area plate, the curvature of which essentially corresponds to that of the boom 3, where appropriate additional finger depressions 21 can be provided, on the one hand, for the best possible grip of the sailing hand 17 to ensure and on the other hand to prevent that the operating handle 16 can cut into the sail hand 17. To the abutment 15 this plate is with a. Provide incision so that two fork arms forming the clamping arm 14 are formed, which can be pivoted on both sides of the sleeve 12 on a bearing axis 22.

Bei der abgewandelten Ausführungsform einer Klemmvorrichtung 11' nach Fig. 3 ist eine nach Art einer Rohrschelle ausgebildete Hülse 12' auf dem Gabelbaum 3 angebracht, in deren vom Gabelbaum 3 abstehenden Flanschen 23 ein Klemmhebel 13' um eine Lagerachse 22' schwenkbar gelagert ist. Zwischen diesen Flanschen 23 ist - unmittelbar benachbart zum Gabelbaum 3 - ein Widerlager 15' angeordnet, gegen das die Trapezleine 8 von einer mit einer Verzahnung 24 versehenen Klemmbacke 14' gedrückt wird. Diese Klemmbacke 14' ist zwischen der Lagerachse 22' und einem Betätigungsgriff 16' ausgebildet. Der Klemmhebel 13' ist also als einarmiger Hebel ausgebildet. Am freien Ende des Betätigungsgriffs 16' ist die Trapezleine 8 durch diesen geführt.In the modified embodiment of a clamping device 11 'according to FIG. 3, a sleeve 12' designed in the manner of a pipe clamp is attached to the boom 3, in whose flanges 23 projecting from the boom 3 a clamping lever 13 'is pivotally mounted about a bearing axis 22'. Between these Flanges 23 - directly adjacent to the boom 3 - an abutment 15 'is arranged, against which the trapezoid line 8 is pressed by a clamping jaw 14' provided with teeth 24 '. This jaw 14 'is formed between the bearing axis 22' and an operating handle 16 '. The clamping lever 13 'is thus designed as a one-armed lever. At the free end of the operating handle 16 ', the trapezoid line 8 is guided through it.

Anstelle der durch einen Gummizug gebildeten elastischen Leine 18 kann die Trapezleine 8 auch über ihr Ende lo hinaus verlängert sein, welches dann auf einer Federschnurrolle aufgewickelt ist. Entscheidend ist, daß die Trapezleine 8 nach Lösen der Klemmvorrichtung 11 bzw. 11' vom Surfer 5 relativ zum Gabelbaum 3 ausgezogen werden kann und nach Aufhebung der Zugkraft wieder eingezogen wird.Instead of the elastic line 18 formed by an elastic band, the trapezoid line 8 can also be extended beyond its end lo, which is then wound on a spring cord. It is crucial that the trapeze line 8 can be pulled out by the surfer 5 relative to the boom 3 after loosening the clamping device 11 or 11 'and is retracted after the pulling force has been released.

Anstelle der auf den Gabelbaum 3 aufzuklemmenden Hülse 12 bzw. 12' kann auch ein längs des Gabelbaums 3 verschiebbarer Schlitten vorgesehen sein, der mit einer Arretiervorrichtung versehen ist, die selbsttätig mit der Verschwenkung des Klemmhebels auch eine Verschiebearretierung in der jeweiligen Längsstellung am Gabelbaum 3 bewirkt.Instead of the sleeve 12 or 12 'to be clamped onto the boom 3, a slide which can be moved along the boom 3 can also be provided, which is provided with a locking device which, when the clamping lever is pivoted, also automatically locks the boom in the respective longitudinal position on the boom 3 .

Darüber hinaus kann auch eine Klemmvorrichtung vorgesehen sein, die mehrere stiftartige, im Abstand aus dem Gabelbaum 3 herausstehende Betätigungsgriffe aufweist, wobei diese auch durch eine gemeinsame Platte verbunden sein können, so daß unabhängig von der gewünschten Position der Segelhand stets eine Klemmung der Trapezleine mit selbsttätiger Freigabe derselben beim Lösen der Segelhand erzielt werden kann.In addition, a clamping device can also be provided, which has a plurality of pin-like actuating handles protruding at a distance from the boom 3, whereby these can also be connected by a common plate, so that regardless of the desired position of the sailing hand, the trapezoid line is always clamped with an automatic one Release of the same can be achieved when releasing the sail hand.

Die Klemmvorrichtung 11 bzw. 11' kann in beliebiger Stellung am Umfang des Gabelbaums 3 angebracht sein; sie kann also insbesondere so angebracht sein, daß der Betätigungsgriff 16 bzw. 16' mit dem Handballen erfaßt wird. Eine solche Anbringung hat den Vorteil, daß auch nach Lösen der Klemmvorrichtung 11 bzw. 11' die Finger der Segelhand 17 den Gabelbaum 3 umgreifen.The clamping device 11 or 11 'can be attached in any position on the circumference of the boom 3; it can in particular be attached so that the operating handle 16 or 16 'is gripped with the ball of the hand. Such an attachment has the advantage that even after loosening the clamping device 11 or 11 ', the fingers of the sail hand 17 grip around the boom 3.

Weiterhin soll das Lösen der Klemmvorrichtung 11 bzw. 11' nach dem Loslassen des Betätigungsgriffs 16 bzw. 16' schlagartig erfolgen, so daß die Trapezleine 8 sofort frei ist. Dies kann beispielsweise durch eine Feder erreicht werden, die den Betätigungsgriff 16 bzw. 16' nach dem Lösen der Segelhand 17 öffnet.Furthermore, the release of the clamping device 11 or 11 'should take place suddenly after releasing the actuating handle 16 or 16', so that the trapezoid line 8 is immediately free. This can be achieved, for example, by a spring which opens the operating handle 16 or 16 'after the sail hand 17 has been released.
