Abstract

The keel comprises a curved wing profile (1) which is used as a paddle driven by the motion of the waves, generating pump motion acting as a propulsion force for the boat.

Description

       

  



  Die Erfindung ist im unabhängigen Anspruch 1 als Kielvorrichtung an einem Bootsrumpf definiert und beinhaltet, wie in der einzigen Figur dargestellt, einen Flügelprofilbogen 1, welcher mit der Bootsbewegung im Wellengang Pumpbewegungen erzeugt und Vortrieb leistet. Der Flügelprofilbogen 1 ist in einem Stück und mit dem Bootsrumpf fest verbunden, er kann sowohl als Rundspant, wie auch als Knickspant, als Yachtkiel oder als Kielschwert wie auch als Jollenschwert ausgelegt sein. Der Flügelprofilbogen 1 gefüllt mit Kielblei wirkt bei Krängung als exzentrischer Gewichtsausleger.

   Der Querschnitt des Flügelprofilbogen 1 ist im Wesentlichen eine asymmetrische halbe Tropfenform 2, wobei konkav als die nach aussen liegende und konvex als die nach innen liegende Seite am Querschnittsprofil bezeichnet ist. 
 
   Fig. 1 zeigt den Flügelprofilbogen in einem Stück integral als Kielpaddel an einem Bootsrumpf fest verbunden, welcher mit der Bootsbewegung im Wellengang Pumpbewegungen erzeugt und Vortrieb leistet. 
   Fig. 2 zeigt den Querschnitt des Flügelprofilbogen 1 im Wesentlichen als eine asymmetrische, halbe Tropfenform, wobei konkav als die nach aussen liegende und konvex als die nach innen liegende Seite am Querschnittsprofil bezeichnet ist, was gefüllt mit Kielblei bei Krängung als exzentrischer Gewichtsausleger wirkt. 




  



  The invention is defined in independent claim 1 as a keel device on a boat hull and, as shown in the single figure, includes a wing profile arch 1, which generates pumping movements and propels with the boat movement in the waves. The wing profile arch 1 is in one piece and firmly connected to the boat hull, it can be designed both as a round frame, as well as an articulated frame, as a yacht keel or as a keel sword as well as a dinghy sword. The wing profile arch 1 filled with keel lead acts as an eccentric weight arm when heeling.

   The cross section of the wing profile arch 1 is essentially an asymmetrical half drop shape 2, concave being referred to as the outward side and convex as the inward side of the cross sectional profile.
 
   Fig. 1 shows the wing profile arch integrally connected in one piece as a keel paddle to a boat hull, which generates pumping movements and propulsion with the boat movement in the waves.
   Fig. 2 shows the cross section of the wing profile arch 1 essentially as an asymmetrical, half teardrop shape, concave as the outward and convex as the inward side of the cross-sectional profile, which is filled with keel lead when heeling as an eccentric weight arm.
