Abstract
Description
Die Erfindung betrifft eine Scherenvorrichtung zum Zusammen- und Auseinanderschieben der beiden Rümpfe eines Katamarans.The invention relates to a scissor device for and pushing apart the two hulls of a catamaran.
Durch die Erfindung wird das Problem gelöst, einen Katamaran, mit seiner ihm eigenen extremen Breite, im Gegensatz zu anderen Sportbooten, in einfachster Weise auf eine minimale Breite zusammen zu ziehen. Speziell betrifft diese Erfindung die immer beliebter werdenden trailerbaren, bewohnbaren Kata marane mit z. B. den Abmessungen: Länge über Alles: 8 m, Breite über Alles: 5 m, Rumpfbreite: 1 m. Diese Katamarane werden "Micro-Multihull" genannt und in Frankreich nennt man sie "Formule 28". In diese Multihullklasse gehören Katamarane und Trimarane. Erforderlich ist eine min. Breite von 2,50 m beim Trailern eines Katamarans, und eine minimale Breite wird gewünscht bei der Liegeplatzsuche in Yachthäfen und um mit einem Katamaran Flüsse oder Kanäle befahren zu können. Das Slippen (zu Wasser bringen) eines Katamarans mit Scheren vorrichtung wird wesentlich vereinfacht, da der Trailer als Slippwagen benutzt wird, und der Katamaran in seinem zusammen geschobenem, stabilem Zustand ins Wasser gefahren wird, und in der Schwimmlage, durch das Drehen einer Winsch, ausein andergeschoben wird. Soll der Katamaran aus dem Wasser wieder auf den Trailer gebracht werden, wird in umgekehrter Reihen folge verfahren.The invention solves the problem of a catamaran, with its own extreme width, as opposed to other pleasure craft, in the simplest way to a minimum Pull together width. In particular, this invention relates the increasingly popular trailerable, habitable kata marane with z. B. the dimensions: overall length: 8 m, width Overall: 5 m, hull width: 1 m. These are catamarans Called "Micro-Multihull" and in France they are called "Formule 28". Catamarans belong to this multihull class and trimarans. A min. Width of 2.50 m when trailering a catamaran, and a minimal width becomes desired when looking for a berth in marinas and around with to be able to sail rivers or canals in a catamaran. Slipping a catamaran with scissors device is significantly simplified since the trailer as Slipper car is used, and the catamaran in its together pushed, stable state into the water, and in the floating position by turning a winch is pushed. Shall the catamaran get out of the water again put on the trailer is in reverse order follow procedure.
Eine Ausführung der Erfindung ist in der Zeichnung dar gestellt und wird im folgenden näher beschrieben:An embodiment of the invention is shown in the drawing and is described in more detail below:
An der vorderen Innenseite der Rümpfe ist jeweils eine vertikale Achse (1) angebracht. Um diese Achse sind die vorderen Enden der Schere (2) drehbar gelagert. An der hin teren Innenseite der Rümpfe sind horizontale Schienen (3) angebracht. In diesen Schienen (3) werden die hinteren Enden der Schere (4) geführt. Soll der Katamaran auf dem Wasser zusammengeschoben werden, so entfernt man die beiden Quer träger (5), welche nur beim Segeln erforderlich sind. An einem hinterem Ende der Schere ist ein Seil (6) befestigt. Dieses Seil wird um eine Winsch (7 ) gelegt, die hinten auf einem Rumpf angebracht ist. Durch Drehen der Winschkurbel bewegen sich die hinteren Scherenenden (4) in ihren Schie nen nach achtern, und die beiden Rümpfe schieben sich zu sammen. Soll der Katamaran aus seinem zusammengeschobenem Zustand auseinander gefahren werden, so legt man das Seil um eine Umlenkrolle (8) wieder auf die Winsch (7), und durch Drehen der Kurbel bewegen sich die Scherenenden (4) in ihren Schienen (3) nach vorne, und die Rümpfe des Kata marans fahren auseinander. An den jeweiligen Endpunkten auf der Schiene (3) können die Scherenenden (4) arretiert werden. Beim Zusammenschieben der Rümpfe kann sogar der Segelmast stehenbleiben. Der Mastfuß ist auf dem Dreh punkt der Schere (9) angebracht. Vor dem Zusammenschieben werden zwei Stangen im oberen Teil am Mast eingehakt, und die unteren Stangenenden jeweils am Buk der Rümpfe einge hakt. Die beiden Stangen ergeben mit dem Mast zusammen einen "Dreifuß". Beim Zusammenschieben wandert das untere Mastende, welches drehbar im Mastfuß gelagert ist, mit dem Scherendrehpunkt (9) nach achtern.A vertical axis ( 1 ) is attached to the front inside of each hull. The front ends of the scissors ( 2 ) are rotatably mounted about this axis. Horizontal rails ( 3 ) are attached to the rear inside of the hulls. The rear ends of the scissors ( 4 ) are guided in these rails ( 3 ). If the catamaran is pushed together on the water, you remove the two cross members ( 5 ), which are only required when sailing. A rope ( 6 ) is attached to a rear end of the scissors. This rope is placed around a winch ( 7 ), which is attached to the back of a hull. By turning the winch handle, the rear ends of the scissors ( 4 ) move aft in their rails, and the two hulls move together. If the catamaran is to be pulled apart from its pushed-together state, the rope is placed around the pulley ( 8 ) on the winch ( 7 ) again, and by turning the crank the scissor ends ( 4 ) move forward in their rails ( 3 ) , and the hulls of the Kata marans spread apart. The scissor ends ( 4 ) can be locked at the respective end points on the rail ( 3 ). When the hulls are pushed together, even the sail mast can stop. The mast foot is attached to the pivot point of the scissors ( 9 ). Before pushing together, two rods are hooked into the upper part of the mast, and the lower rod ends are hooked onto the buk of the hulls. The two poles together with the mast form a "tripod". When pushed together, the lower mast end, which is rotatably mounted in the mast base, moves aft with the scissor pivot point ( 9 ).
