Beschreibung der Erfindung:Description of the invention:

Elastische Flosse oder Flossen zum Antrieb von Wasserfahrzeugen, Schwimmkörpern und Surfbrettern durch Muskelkraft.Elastic fin or fins for propelling watercraft, floats and surfboards by muscular power.

Muskelbetriebene Wasserfahrzeuge werden üblicherweise durch Paddel oder Ruder angetrieben. Schwimmer und Taucher erreichen einen größeren Vortrieb durch das Anlegen von Flossen.Human-powered watercraft are usually propelled by paddles or oars. Swimmers and divers achieve greater propulsion by wearing fins.

Der im Schutzanspruch angegebenen Erfindung liegt die Idee zugrunde, einen auf Muskelkraft beruhenden Vortrieb für Wasserfahrzeuge, Schwimmkörper oder Surfbretter zu erreichen, indem sie mit einer oderer mehreren elastischen Flossen ausgestattet werden.The invention specified in the protection claim is based on the idea of achieving propulsion based on muscle power for watercraft, floating bodies or surfboards by equipping them with one or more elastic fins.

Durch Tretbewegungen eines auf dem Wasserfahrzeug (3) stehenden Benutzers bewegt sich dieses um seine Längsachse im Wasser hin und her. Eine oder mehrere angebrachte elastische Flossen (1) machen diese Bewegungen durch das Wasser mit und erzeugen einen Vortrieb.Through pedaling movements of a user standing on the watercraft (3), it moves back and forth in the water around its longitudinal axis. One or more attached elastic fins (1) follow these movements through the water and generate propulsion.

Mit der Erfindung können völlig neue Wassersportgeräte geschaffen werden. Damit ausgestattete Surfbretter können bei Windstille als Wassersportgerät neu genutzt werden.The invention makes it possible to create completely new water sports equipment. Surfboards equipped with it can be used as water sports equipment when there is no wind.

Je ein Ausfuhrungsbeispiele mit einer und mit zwei Flossen werden durch die beigefügten Zeichnungen näher erläutert:An example design with one and two fins is explained in more detail in the attached drawings:
