Description
Klappenschwert für Segelboote. Den Gegenstand des Hauptpatentes bildet ein Klappenschwert, bei dem die Schwerthälften durch ein Keilstück in die Hochstellung gebracht und in der Tiefstellung durch einen über die hlappenränder fassenden Block gehalten werden. Die den Gegenstand des vorliegenden Zusatzpatentes bildende Ausführung besteht nun darin, daß die durch Eigengewicht herunterfallenden Schwerthälften durch ein Keilstück in die Tiefstellung gedrückt und in dieser Stellung gesichert werden, während für das Hochstellen der Klappen eine besondere Windevorrichtung vorgesehen ist.Flap sword for sailboats. The subject of the main patent forms a flap sword, in which the sword halves are raised by a wedge brought and in the subscript by a block that extends over the edges of the flap being held. The execution forming the subject of the present additional patent is now that the sword halves falling down by their own weight through a wedge is pressed into the lower position and secured in this position, while a special winch device is provided for raising the flaps is.
Auf der Zeichnung ist die Anordnung im Querschnitt des Bootes schematisch in Abb. z bis 3 in drei verschiedenen Stellungen dargestellt; Abb.4 ist eine Draufsicht auf die nebeneinanderliegenden Schwertklappen.In the drawing, the arrangement in the cross section of the boat is schematic shown in Fig. z to 3 in three different positions; Fig.4 is a top view on the sword flaps lying next to each other.
Wie bei der Ausführung nach dem Hauptpatent besteht das Schwert aus zwei Klappen c und d, die beweglich an dem am Schiffsboden a befindlichen Totkiel b angelenkt sind. Jede Klappe hat eine oder mehrere nach oben gerichtete und seitlich abstehende Laschen m, n, die in der Tiefstellung des Schwertes einen Winkel miteinander bilden. In diesen von den Laschen m und n gebildeten Winkel wird ein Keilstück p gedrückt, wodurch die Laschen auseinander, die Klappen selbst aber gegeneinander gedrückt werden. Durch einen entsprechend starken Druck des Keiles p werden also die Klappen c und d nicht nur in der Tiefstellung gehalten, sondern sie werden dauernd in der geschlossenen Lage gesichert und wirken wie ein fest eingebauter Kiel. Um aber vorn das Eindringen von Wasser zwischen die beiden Klappen zu verhindern, ist die eine Klappe c gegenüber der anderen Klappe d etwas verkürzt und ihre Vorderkante legt sich hinter den entsprechend verbreiterten vorderen Ansatz r der Klappe d (Abb. 4.). Dadurch ist die vordere Fuge zwischen den beiden Klappen verdeckt.As in the embodiment according to the main patent, the sword consists of two flaps c and d, which are movably hinged to the dead keel b located on the ship's bottom a. Each flap has one or more upwardly directed and laterally protruding tabs m, n, which form an angle with one another in the lower position of the sword. A wedge p is pressed into this angle formed by the tabs m and n, whereby the tabs are pressed apart, but the flaps themselves are pressed against each other. With a correspondingly strong pressure of the wedge p, the flaps c and d are not only held in the low position, but they are permanently secured in the closed position and act like a permanently installed keel. However, in order to prevent water from penetrating between the two flaps at the front, one flap c is slightly shorter than the other flap d and its front edge lies behind the correspondingly widened front attachment r of flap d (Fig. 4.). This hides the front joint between the two flaps.
Zum Hochstellen der Klappen ist eine Windevorrichtung angeordnet, deren Seile an den Laschen ei und n angreifen. Nach Hochziehen des Keiles p werden Klappen mit Hilfe der Windevorrichtung so weit hochgeschwenkt, daß sie sich gegen den Schiffsboden a oder gegen dort noch besonders vorgesehene Schlingerkiele anlegen. In dieser Stellung bilden sie wieder einen wirksamen Schutz des Schiffsbodens gegen Beschädigungen beim Aufsetzen oder Stoßen auf Grund.A winch device is arranged to raise the flaps, whose ropes attack the straps ei and n. After pulling up the wedge p will be Flaps swiveled up so far with the help of the winch that they are against Lay the ship's bottom a or against the bilge keels specially provided there. In this position, they again provide effective protection against the bottom of the ship Damage when touching down or hitting the ground.
