The clasp (12) can be clamped to a buckle (13) with adjustable clamping force. <IMAGE>

Description

Einer der Arbeitsschritte beim Aufriggen eines Surfbrettes besteht darin, den Gabelbaum mit dem Masten des Riggs zu verbinden. Bei herkömmlichen Surfriggs weist der Gabelbaum an seinem mastseitigen Ende ein Formstück auf, welches im wesentlichen V-förmig oder rund ist und in dessen Schenkel die Gabelenden eingesteckt sind. Beim Aufriggen wird der Gabelbaum mit einem als Masttampen bezeichneten Seil in einem etwa rechten Winkel zum Masten dicht an diesen gebunden, um eine feste Verbindung zu erreichen. Hierzu legt der Surfer mit dem einen Ende des Masttampens einen Stopperstek oder ähnlichen Knoten um den Masten. Den verbleibenden Rest des Masttampens führt er durch ein dafür vorgesehenes Loch im Formstück und bindet Mast und Gabelbaum fest zusammen, wobei das Ende des Tampens anschliessend durch eine am Gabelbaum vorhandene Klemme geführt wird, welche das Lösen der Ver bindung verhindert. Durch Abwinkeln des Gabelbaumes von der etwa 90 Grad-Lage wird der Befestigungstampen so stark gespannt, dass die V-förmigen oder runden Auflageflächen des Formstückes den Masten verformen oder beschädigen können, was mitunter gar zu seinem Bruch führt. Diese bisher angewendete Technik bringt einige entscheidende Nachteile mit sich. Zum einen macht sie das Aufriggen aufwendig und verlangt insbesondere vom weniger geübten Surfer, dass er jederzeit den Stopperstek oder ähnliche Befestigungsknoten beherrscht. Nur solche Knoten gewährleisten bisher eine segeltüchtige Verbindung zwischen Mast und Gabelbaum. Das korrekte Anlegen dieser Knoten erfordert eine gewisse Routine. Zum anderen können gerade auch beim Surfen Nachteile entstehen. Besonders bei Anfängern vermag sich der Gabelbaum infolge falscher Handhabung oft relativ zum Masten zu verdrehen. Da der Gabelbaum mit seiner grossen Länge einen eigentlichen Kraftarm darstellt, erfolgt bei entsprechenden Bewegungen ein beträchtlicher Zug des Masttampens auf den Masten, der aus einem Aluminium- oder Kunststoffrohr besteht und deshalb hohl ist. Dies kann soweit gehen, dass der Stopperstek am Masten derart stark zusammengezogen wird und die Kanten der Auflageflächen so stark gegen den Masten gepresst werden, dass der Masten eingedrückt wird. Auch wenn er nur wenig eingedrückt wird, so weist er dort fortan eine bedeutende Schwachstelle auf, die bei starker Beanspruchung zum Knicken führen kann.One of the steps in rigging a surfboard is to connect the boom to the mast of the rig. In conventional surf rigs, the boom has a shaped piece on its mast-side end, which is essentially V-shaped or round and in the leg of which the fork ends are inserted. When rigging, the boom is tied tightly to the mast at a right angle to the mast using a rope known as mast rope, in order to achieve a firm connection. For this purpose, the surfer puts a stopper or similar knot around the mast with one end of the mast mast. The rest of the mast tamping he leads through a hole provided in the fitting and firmly binds mast and boom, whereby the end of the tamping is then passed through a clamp on the boom, which the release of the Ver bond prevented. By angling the boom from the approximately 90 degree position, the fastening ropes are stretched so much that the V-shaped or round contact surfaces of the fitting can deform or damage the masts, which can even lead to its breakage. This technique, which has been used up to now, has some decisive disadvantages. On the one hand, it makes rigging complex and, in particular, requires less experienced surfers to master the stopper stick or similar fastening knots at all times. So far, only such knots guarantee a sailable connection between mast and boom. The correct creation of these nodes requires a certain routine. On the other hand, disadvantages can also arise when surfing. Especially with beginners, the boom can twist relative to the mast due to incorrect handling. Since the boom, with its long length, represents an actual power arm, the mast tamping on the masts, which consists of an aluminum or plastic tube and is therefore hollow, pulls considerably when the movements are made accordingly. This can go so far that the stopper plug on the mast is contracted so much and the edges of the contact surfaces so strongly against the Masts are pressed so that the mast is pushed in. Even if it is only pushed in a little, it shows a significant weak point from now on, which can lead to buckling under heavy use.

Ein weiterer, entscheidender Nachteil bisheriger Verbindungen von Gabelbaum und Masten besteht darin, dass die Aeste des Gabelbaumes durch das Formstück am mastseitigen Ende des Gabelbaumes fest miteinander verbunden sind. Um den Gabelbaum an den Masten anzulegen, muss dieser, da er ja geschlossen ist, über den Masten gestülpt werden, was relativ umständlich ist.Another, decisive disadvantage of previous connections of boom and masts is that the branches of the boom are firmly connected to each other by the fitting at the mast end of the boom. To put the boom on the masts, since it is closed, it has to be put over the masts, which is relatively cumbersome.

Die Aufgabe der vorliegenden Erfindung ist es, eine Verbindung zwischen Gabelbaum und Mast eines Riggs zu schaffen, welche einfacher zu handhaben ist und ein mögliches Knicken zu verhindern hilft.The object of the present invention is to provide a connection between the boom and mast of a rig, which is easier to handle and helps prevent possible kinking.

Diese Aufgabe wird gelöst von einer Vorrichtung zur Verbindung von Gabelbaum und Mast eines Riggs, wobei die Vorrichtung mit den mastseitigen Enden des Gabelbaumes kraftschlüssig verbunden ist, die sich dadurch auszeichnet, dass sie aus zwei einzelnen Formstücken besteht, die je fest mit einem Ast des Gabelbaumes verbunden sind und die zwischen sich einen Freiraum zur Aufnahme des Mastens je um mindestens 90 Grad um schliessen, ferner dass Klemmittel vorhanden sind, mittels denen die beiden Formstücke lösbar um den Masten zusammenklemmbar sind.This object is achieved by a device for connecting the boom and mast of a rig, the device being non-positively connected to the mast-side ends of the boom, which is characterized in that it consists of two individual shaped pieces, each of which is fixed to a branch of the boom are connected and between them a free space for receiving the mast by at least 90 degrees close, furthermore that there are clamping means by means of which the two fittings can be releasably clamped together around the masts.

In den Zeichnungen ist eine vorteilhafte Ausführung der erfindungsgemässen Vorrichtung beispielsweise dargestellt.An advantageous embodiment of the device according to the invention is shown in the drawings, for example.

Es zeigt:

  • Figur 1 die Vorrichtung in Draufsicht,
  • Figur 2 die Vorrichtung in perspektivischer Ansicht.
It shows:
  • 1 shows the device in plan view,
  • Figure 2 shows the device in perspective.

In der Figur 1 sind alle erfindungswesentlichen Bestandtei le der Vorrichtung ersichtlich. Die beiden Formstücke 1,2 umschliessen den hier im Querschnitt dargestellten Mast 3. Jedes Formstück 1,2 hat je eine zylindrische Ausnehmung 4, in welche die Gabelenden 5 einsteckbar sind. Um einen stabileren Klemmgriff zu erzielen, sind die Klemmflächen 6 als Segmente einer Zylinderinnenwand geformt und beidseits der Vorrichtung in Mastrichtung etwas verlängert, wodurch Lippen 7 gebildet werden, die zur Verstärkung über Rippen verstrebt sein können. Die Klemmflächen 6 sind mit einem rutschfesten, gummi elastischen Kunststoffmaterial 10 versehen. Die beiden Formstücke 1,2 weisen Löcher 11 auf, durch welche die Startschotte geführt werden kann. Am einen Formstück ist eine flexible Lasche 8 befestigt, die um mindestens 60 Grad um den zu umschliessenden Masten 3 herumgeführt ist. Am Ende dieser Lasche 8 ist ein Haken 9 gebildet, an dem eine U-förmige Spange 12 einhängbar ist. Die Lippen 7 werden grösstenteils umschlossen von der Lasche 8 und der Spange 12, die mittels einer Schnalle 13 gespannt werden. Insgesamt umspannen die Klemmspange 12 und die Lasche 8 zusammen den einzuklemmenden Masten 3 um mindestens 180 Grad. Die Klemmkraft wird dadurch kontinuierlich auf den ganzen Umfang des Mastens 3 verteilt. Die Lasche ist mit Vorteil aus Metall hergestellt und mit dem Formstück 2 vernietet. Die beiden Schenkelenden 15 der U-förmigen Spange 12 sind schwenkbar an der Schnalle 13 befestigt. Die Schnalle 13 selbst ist so ausgebildet, dass sie nach dem Hebelgesetz arbeitet. Sie ist schwenkbar auf einer speziell geformten Auflagefläche 20 angelegt, welche eine Reihe von gelenkpfannenartigen Vertiefungen 21 aufweist. Darin ist die Schnalle 13 um den durch ihren Gelenkkopf 22 gebildeten Drehpunkt 16 schwenkbar. Der Abstand zwischen diesem Drehpunkt 16 und dem Befestigungsort 17 bildet dadurch einen Lastarm, während der Bereich zwischen Drehpunkt 16 und Schnallengriff 18 einen Kraftarm bildet. Durch die Tatsache, dass die Klemmspange 12 in Schliessrichtung der Schnalle 13 den Drehpunkt 16 als Zenith passiert kommt die Spange 12 bei geschlossener Schnalle 13 zwischen den Drehpunkt 16 und den Schnallengriff 18 zu liegen. Dadurch wird eine Selbsthemmung erreicht, welche wirksam das selbständige Oeffnen der Schnalle 13 verhindert. Das Ende 19 des Schnallengriffs 18 schliesst bündig an den Gabelbaum 5 an, womit ein unbeabsichtigtes Oeffnen der Schnalle 13 verhindert wird. Ebenfalls wird dadurch die Verletzungsgefahr an der geschlossenen Schnalle 13 reduziert. Durch jede Vertiefung 21 der Auflagefläche 20 wird eine Gelenkpfanne 21 für den einen Gelenkkopf 22 bildenden Teil der Schnalle 13 gebildet. Je nachdem, in welche Vertiefung 21 dieser Gelenkkopf 22 gelegt wird, resultiert eine mehr oder weniger starke Spann- bzw. Klemmkraft. Da die beiden Formstücke 1 und 2 völlig symmetrisch sein können, kann ihre Herstellung mit bloss einem Spritzwerkzeug erfolgen, das zudem kleiner und daher günstiger ist, als ein solches für ein herkömmliches, V-förmiges Formstück.In Figure 1, all components of the device essential to the invention can be seen. The two shaped pieces 1, 2 surround the mast 3 shown here in cross section. Each shaped piece 1, 2 has a cylindrical recess 4, into which the fork ends 5 can be inserted. In order to achieve a more stable clamping grip, the clamping surfaces 6 are shaped as segments of an inner cylinder wall and are somewhat extended on both sides of the device in the direction of the mast, whereby lips 7 are formed which can be braced over ribs for reinforcement. The clamping surfaces 6 are with a non-slip, rubber provided elastic plastic material 10. The two shaped pieces 1, 2 have holes 11 through which the starting bulkhead can be guided. A flexible tab 8 is attached to one shaped piece and is guided around the mast 3 to be enclosed by at least 60 degrees. At the end of this tab 8, a hook 9 is formed, on which a U-shaped clip 12 can be hung. The lips 7 are largely enclosed by the tab 8 and the clasp 12, which are tensioned by means of a buckle 13. Overall, the clamping clip 12 and the tab 8 together span the masts 3 to be clamped in by at least 180 degrees. The clamping force is thereby continuously distributed over the entire circumference of the mast 3. The tab is advantageously made of metal and riveted to the fitting 2. The two leg ends 15 of the U-shaped clip 12 are pivotally attached to the buckle 13. The buckle 13 itself is designed so that it works according to the lever law. It is pivotably placed on a specially shaped support surface 20, which has a series of joint socket-like depressions 21. In it, the buckle 13 can be pivoted about the pivot point 16 formed by its joint head 22. The distance between this fulcrum 16 and the attachment location 17th thereby forms a load arm, while the area between pivot point 16 and buckle handle 18 forms a power arm. Due to the fact that the clamping clip 12 passes the pivot point 16 as zenith in the closing direction of the buckle 13, the clip 12 comes to lie between the pivot point 16 and the buckle handle 18 when the buckle 13 is closed. This achieves self-locking, which effectively prevents the buckle 13 from opening independently. The end 19 of the buckle handle 18 is flush with the boom 5, thereby preventing the buckle 13 from being inadvertently opened. This also reduces the risk of injury to the closed buckle 13. A joint socket 21 for the part of the buckle 13 forming a joint head 22 is formed by each recess 21 of the bearing surface 20. Depending on the recess 21 in which this joint head 22 is placed, a more or less strong clamping or clamping force results. Since the two fittings 1 and 2 can be completely symmetrical, they can be produced using only one injection mold, which is also smaller and therefore cheaper than one for a conventional V-shaped fitting.

Die Ausgestaltung der einzelnen Bestandteile der erfindungsgemässen Vorrichtung kann durchaus vom hier beschriebenen Beispiel abweichen.The design of the individual components of the The device according to the invention may well deviate from the example described here.

In Figur 2 ist die in Figur 1 gezeigte und bereits beschriebene Ausführung perspektivisch dargestellt. Dabei ist deutlich erkennbar, dass die Klemmflächen 6 beidseits der Vorrichtung etwas verlängert sind, indem sie Lippen 7 bilden. Dadurch wird der Klemmgriff verstärkt und die Verwindungsstabilität gegenüber dem Masten 3 vergrössert. Damit die Lippen 7 die auftretenden Kräfte besser absorbieren können, können sie mit Rippen verstärkt sein. Die Klemmflächen 6 sind zudem mit einem rutschfesten, gummielastischen Kunststoffmaterial 10 versehen. Dadurch wird der Mast 3 geschont und der Gabelbaum 5 kann relativ zum Masten 3 je nach gewählter Klemmkraft etwas bewegt werden.In Figure 2, the embodiment shown in Figure 1 and already described is shown in perspective. It can be clearly seen that the clamping surfaces 6 on both sides of the device are somewhat extended by forming lips 7. As a result, the clamping handle is reinforced and the torsional stability compared to the mast 3 is increased. So that the lips 7 can better absorb the forces that occur, they can be reinforced with ribs. The clamping surfaces 6 are also provided with a non-slip, rubber-elastic plastic material 10. This protects the mast 3 and the boom 5 can be moved somewhat relative to the mast 3 depending on the selected clamping force.

Die erfindungsgemässe Vorrichtung erlaubt ein schnelleres Aufriggen des Surfbrettes. Weil der Gabelbaum vorne teilbar ist, seine beiden Aeste also auseinanderspreizbar sind, ka nn er einfach um das Rigg, beziehungsweise um das Segel und den Masten angelegt werden, wonach die Vorrichtung mittels der Schnalle zusammengeklemmt wird. Zudem ist die Handhabung dieser Vorrichtung bedeutend einfacher als der Umgang mit dem Masttampen, welcher nun völlig entfällt. Der Surfer braucht den Stopperstek oder andere geeignete Knoten nicht mehr zu beherrschen und kann deshalb auf dem Wasser keine Ueberraschungen mehr erleben, die aus einem falsch angelegten Befestigungsknoten resultieren können. Auch bei Stürzen und sonstigen aussergewöhnlichen Bewegungen des Surfers bleibt die saubere Verbindung zwischen Mast 3 und Gabelbaum 5 stets bestehen. Es ist kein Seil mehr vorhanden, das in solchen Situationen den Masten durch starke Zusammenschnürung eindrücken und beschädigen könnte. Die Auflageflächen verdrehen weniger und deren Kanten können den Masten nicht mehr eindrücken. Somit können auch keine geschwächten Stellen am Masten mehr entstehen und eine Knickung aus diesem Grund ist nicht mehr möglich. The device according to the invention allows the surfboard to be rigged up more quickly. Because the boom is divisible at the front, i.e. its two branches can be spread apart, it can simply be placed around the rig, or around the sail and masts, after which the device is clamped together using the buckle. In addition, the handling of this device is significantly easier than the handling of the mast rope, which now completely eliminated. The surfer no longer needs to master the stopper stick or other suitable knots and can therefore no longer experience surprises on the water that can result from an incorrectly attached fastening knot. Even in the event of falls and other unusual movements by the surfer, the clean connection between mast 3 and boom 5 always remains. There is no longer any rope that could compress and damage the masts in such situations due to strong constriction. The contact surfaces twist less and their edges can no longer impress the masts. As a result, weakened areas on the masts can no longer arise and kinking is no longer possible for this reason.
