Description

Vorrichtung zum Stellen und Legen des Mastes eines Segelbootes Beschreibung Device for placing and placing the mast of a sailboat Description
Die Erfindung betrifft eine Vorrichtung zum Stellen und Legen des Mastes eines Segelbootes, die auch während der Fahrt durchs Wasser genutzt werden kann.The invention relates to a device for placing and placing the mast of a sailboat, which can also be used while driving through the water.
Aus der GB 1 315 301 A ist eine Mastfußstütze für Segelboote bekannt, die einen senkrecht angeordneten Drehzapfen aufweist, der eine vertikale Symmetrieachse bildet, um die der Mast drehbar ist. Außerdem verläuft rechtwinkelig zu dem Drehzapfen ein Splint oder ein Bolzen, der den Mast entweder senkrecht hält oder ein Umlegen in Richtung auf das Deck gestattet.From GB 1 315 301 A a mast foot support for sailboats is known, which has a vertically arranged pivot which forms a vertical axis of symmetry about which the mast is rotatable. In addition, perpendicular to the pivot pin or a bolt that holds the mast either vertically or allows a flip towards the deck.
Die US 7,137,346 Bl offenbart ebenfalls eine Mastlegevorrichtung in Form von zwei Hülsen, die durch ein Gelenk schwenkbar miteinander verbunden sind. Um die Schwenkbewegung zu ermöglichen, ist eine der beiden Hülsen mit einem Verriegelungsstück versehen, das zum Schwenken entfernt werden muß, um Raum für den Schwenkvorgang zu schaffen. Der Mast eines Segelboots wird über die Mastlegevorrichtung geschoben oder aufgesteckt und ruht im normalen Betrieb auf dem Mastschuh des Segelbootes. Wenn der Mast hingegen auf Deck gelegt werden soll, so wird er zunächst bis über die Trennstelle der beiden Hülsen angehoben und dort durch einen Stift fixiert. Danach wird das Verriegelungsstück entfernt und der Mast kann dann vorzugsweise nach hinten geklappt werden.The US 7,137,346 Bl also discloses a mast laying device in the form of two sleeves which are pivotally connected together by a hinge. In order to allow the pivoting movement, one of the two sleeves is provided with a locking piece, which must be removed for pivoting to make room for the pivoting operation. The mast of a sailboat is pushed over the mast laying device or attached and rests in normal operation on the mast shoe of the sailboat. On the other hand, when the mast is to be placed on deck, it is first lifted to above the separation point of the two sleeves and fixed there by a pin. Thereafter, the locking piece is removed and the mast can then preferably be folded back.
In Segelrevieren mit Brücken, Freileitungen und anderen, die Durchfahrtshöhe beschränkenden Hindernissen, ist es von erheblichem Vorteil, wenn der Mast gelegt werden kann. Das Legen und Stellen des Mastes ohne Kran ist in der Regel auf Boote mit Mastlängen bis etwa 12 Meter Länge beschränkt. Sehr kurze Masten können ohne Hilfsmittel durch die Crew gesetzt werden. Ab einer bestimmten Mastlänge sind aber technische Hilfsmittel zum Setzen und Legen des Mastes unverzichtbar. Am bekanntesten ist die Jütt. Sie dient dazu, den Winkel zwischen Mast und Zugseil an der Mastspitze so groß zu machen, daß mit händelbaren Kräften der Mast gelegt und wieder gesetzt werden kann. In der Regel wird zwischen dem Zugseil und einem Festpunkt an Bord ein Flaschenzug montiert. Das Problem, das bei allen bekannten Vorrichtungen auftritt, ist die seitliche Stabilisierung des Mastes während des Legens oder Stellens. Bei Wellenbewegungen, die insbesondere auch durch vorbeifahrende Schiffe erzeugt werden und die zum Rollen des Bootes führen, muß der Mast seitlich abgestützt werden. Wenn dieses nicht erfolgt, dann treten im Schwenklager des Maststuhles bzw. Mastes so große Drehmomente auf, daß das Schwenklager zerstört oder der Mast in diesem Bereich verbogen wird. Dieses Problem kann dadurch verringert werden, daß die Oberwanten in Achsrichtung des Schwenklagers im Relingsbereich befestigt werden. Beim Setzen und Legen des Mastes werden die Oberwanten leicht gelöst und dienen dann der seitlichen Stabilisierung.In sailing areas with bridges, overhead lines and other obstacles that restrict the passage height, it is of considerable advantage if the mast can be laid. The laying and placing of the mast without crane is usually limited to boats with mast lengths up to about 12 meters in length. Very short masts can be set without assistance by the crew. From a certain mast length but technical aids for setting and laying the mast are indispensable. The best known is the Jutt. It serves to make the angle between the mast and the pull rope at the top of the mast so large that the mast can be placed and set again with handleable forces. As a rule, a pulley is mounted between the tow rope and a fixed point on board. The problem that occurs with all known devices is the lateral stabilization of the mast during laying. When wave movements, which are generated in particular by passing ships and lead to the rolling of the boat, the mast must be supported laterally. If this does not happen, then occur in the pivot bearing of the mast or mast so great Torques on that destroys the pivot bearing or the mast is bent in this area. This problem can be reduced by the fact that the upper walls are fixed in the axial direction of the pivot bearing in the railing area. When setting and placing the mast, the upper walls are easily loosened and then serve for lateral stabilization.
Ein zweites Problem besteht darin, daß die oben beschriebenen Vorrichtungen in der Regel nicht unmittelbar während der Fahrt eingesetzt werden können. Denn die bekannten technischen Lösungen benötigen technische Vorrichtungen, die eine Beschädigung des Mastes oder Schwenklagers bei Rollbewegungen des Bootes während des Stellens oder Legens des Mastes verhindern. Diese sind relativ aufwendig und können in der Regel nicht während der Fahrt des Bootes genutzt werden.A second problem is that the devices described above can not usually be used directly while driving. For the known technical solutions require technical devices that prevent damage to the mast or pivot bearing during rolling movements of the boat during placement or laying of the mast. These are relatively expensive and can not be used during the ride of the boat in the rule.
Die vorliegende Erfindung löst die genannten Probleme, indem ein unverstagter Mast gefahren wird und dieser beim Setzen und Legen um eine vertikale Achse drehbar ist. Das Problem der seitlichen Stabilisierung wird erfmdungsgemäß dadurch gelöst, daß der Maststuhl um eine vertikale Achse drehbar gelagert ist, die Dirk die seitlichen Pendelbewegungen des Mastes beim Legen begrenzt und abfedert, wobei der Großbaum fixiert bleibt und das Seil, das am unteren Ende des Klappmastes befestigt ist und dem eigentlichen Setzen und Legen dient, die genannten Pendelbewegungen nicht behindert. Die um eine vertikale Achse drehbare Lagerung des Mastfußes und des Mastes, gekoppelt mit einer auf Spannung gehaltenen Dirk, verhindert das Entstehen großer Drehmomente im Schwenklager, die bei Rollbewegung des Bootes zu Beschädigungen des Mastes oder Mastfußes fuhren können.The present invention solves the above problems by a non-articulated mast is driven and this is rotatable when setting and laying about a vertical axis. The problem of lateral stabilization is erfmdungsgemäß solved by the fact that the mast chair is rotatably mounted about a vertical axis, the Dirk limits the lateral oscillations of the mast when laying and cushioning, the boom remains fixed and the rope attached to the lower end of the folding mast is and serves the actual setting and laying, does not hinder the aforementioned oscillations. The rotatable about a vertical axis storage of Mastfußes and the mast, coupled with a tensioned Dirk, prevents the emergence of large torques in the pivot bearing, which can cause damage to the mast or mast base during rolling motion of the boat.
Die Erfindung kann bei allen Segelbooten, die mit kippbarem Mast ausgerüstet werden sollen, genutzt werden. Besonders vorteilhaft ist sie für Segelboote, bei denen der Mast allein von der Crew aus der Plicht heraus während der Fahrt zum Durchfahren von Brücken gelegt werden soll.The invention can be used in all sailboats that are to be equipped with tilting mast. It is particularly advantageous for sailboats, in which the mast is to be placed alone by the crew out of the cockpit during the journey to drive through bridges.
Die Erfindung wird nun anhand einer Zeichnung näher erläutert; es zeigen:The invention will now be explained in more detail with reference to a drawing; show it:
Fig. 1 ein Ausführungsbeispiel mit stehendem Mast;1 shows an embodiment with a standing mast.
Fig.2 das Ausführungsbeispiel von Fig. 1 mit dem Mast während das Legens. Die in Fig. 1 dargestellte Anordnung besteht aus einem Klappmast 1, der in einem Maststuhl 2 steht und in diesem um eine horizontale Schwenkachse 3 schwenkbar ist. Der Maststuhl 2 ist auf einem Untermast 4 montiert und mit diesem um die vertikale Achse drehbar. Der Untermast 4 wird von einem Lager 12 im Deck 11 und von einem Widerlager 10 auf dem Kiel gehalten.2 shows the embodiment of Fig. 1 with the mast during laying. The arrangement shown in Fig. 1 consists of a folding mast 1, which is in a mast chair 2 and in this about a horizontal pivot axis 3 is pivotable. The mast chair 2 is mounted on a lower mast 4 and rotatable with this about the vertical axis. The lower mast 4 is held by a bearing 12 in the deck 11 and by an abutment 10 on the keel.
Der Klappmast 1 steht in Normalposition senkrecht im Maststuhl 2 und schwenkt beim Legen des Mastes um die Schwenkachse 3. Der Maststuhl 2 ist in der Segelposition arretiert und kann sich dann nicht um die vertikale Achse drehen. Eine zweite Arretierung verhindert, daß der Klappmast um die Schwenkachse kippt. Der Mast ist unverstagt.The folding mast 1 is in normal position vertically in the mast chair 2 and pivots when laying the mast around the pivot axis 3. The mast 2 is locked in the sailing position and can not rotate around the vertical axis then. A second lock prevents the folding mast tilts around the pivot axis. The mast is unsung.
Der Großbaum 5 ist am Maststuhl 2 mit einem Lümmelbeschlag angeschlagen und wird beim Setzen und Legen des Mastes in einer Mastauflage 7 arretiert. Die Dirk 6 vom Masttopp zur Nock des Großbaumes wird beim Setzen und Legen des Mastes stets steif gehalten.The boom 5 is struck on the mast chair 2 with a Lümmelbeschlag and is locked when setting and placing the mast in a mast support 7. The Dirk 6 from the mast top to the nock of the boom is always kept stiff when placing and placing the mast.
Die Fig. 2 zeigt die Anordnung während des Legens des Klappmastes 1. Die Arretierung des Maststuhles 2 und die des Schwenklagers 3 sind bei diesem Vorgang gelöst. Der Klappmast wird nun durch das Seil 8 gehalten, das über eine Winsch 9 gefϊert oder dichtgeholt wird. Beim Legen des Klappmastes wird das Seil 8 gefϊert und die Dirk 6 gleichzeitig dichtgeholt. Durch das Steifhalten der Dirk werden bei Rollbewegungen des Schiffes die seitlichen Bewegungen des Klappmastes stark eingegrenzt und abgefedert. Da der Maststuhl um seine vertikale Achse drehbar ist, entstehen bei den leichten seitlichen Bewegungen des Klappmastes keine zerstörerischen Drehmomente im Schwenklager. Die auf die Dirk wirkenden Kräfte werden über die stabile Mastauflage und die Großschot auf den Schiffskörper abgeführt.Fig. 2 shows the arrangement during the laying of the folding mast 1. The locking of the mast chair 2 and the pivot bearing 3 are solved in this process. The folding mast is now held by the rope 8, which is gefϊert or hauled over a winch 9. When laying the folding mast, the rope is 8 gef undert and the Dirk 6 brought close at the same time. Due to the stiffness of the Dirk, the lateral movements of the folding mast are severely limited and cushioned during roll movements of the ship. Since the mast chair is rotatable about its vertical axis, no destructive torques arise in the pivot bearing with the slight lateral movements of the folding mast. The forces acting on the Dirk are dissipated via the stable mast support and the mainsheet on the hull.
Aus der beispielhaften Beschreibung der Funktionsweise der Mastlegevorrichtung ist ersichtlich, daß der Mast während der Fahrt gelegt und gestellt werden kann, ohne daß die Crew die Plicht verlassen muß. From the exemplary description of the operation of the mast laying apparatus it can be seen that the mast can be placed and placed while driving without the crew having to leave the cockpit.
