Description

Betr.: fatenterteilungsantrag Weitere Personen sind an nachstehend genannter Erfindung nicht beteiligt.Re: application for subdivision of fat More people are at below mentioned invention is not involved.

Erfindung: asserski mit Tretkurbelantrieb. Invention: asserski with crank drive.

Die Erfindung betrifft ein Wasserski, das ein Skifahren auf dem Wasser, unabhängig von der Zugkraft eines Motorbootes ermöglicht. The invention relates to a water ski, which is a skiing on the water, independent of the pulling power of a motorboat.

Der Antrieb erfolgt über eine doppelseitige Tretkurbel und ein an der Antriebswelle angebrachten Propeller, der die erforderliche Schubkraft aufbringt. It is driven by a double-sided crank and an on the propeller attached to the drive shaft, which provides the required thrust.

Derr Wasserski ist durch das zur Verwendung kommende Fertigungsmaterial und durch einen besonders angebrachten Hohlkörper schwimmfähig. The water ski is due to the manufacturing material used and buoyant thanks to a specially attached hollow body.

Lagerung und Getriebeteil sind wahlweise so ausgeführt, das sie 1.. gegen das Eindringen von Wasser geschützt sind, 2. offen gebaut und vom Wasser umspült sind. Bearing and gear part are optionally designed in such a way that they 1 .. are protected against the ingress of water, 2. openly built and surrounded by water are.

Ziel der vorliegenden Erfindung ist es, -über die Tretkurbel und dem Propeller eine eigene genügend große Schubkraft und die daraus resultierende Geschwindigkeit zu erzeugen, daß ein Gleiten des Wasserskis auf der Wassdroberfläche erreicht wird, ohne von einer aueren Schubkraft abhängig zu sein. The aim of the present invention is to -over the crank and the propeller its own sufficiently large thrust and the resulting To generate speed that a glide of the water ski on the water surface is achieved without being dependent on an external thrust.

Patentansprüche: Wasserski (1) mit eigenem Antriebsapparat.Claims: Water ski (1) with its own drive mechanism.

Claims (1)

Antrieb erfolgt über doppelseitiger Tretkurbel (2) und ein an der Antriebswelle angebrachten Propeller (3). Ein am Wasserski angebrachte Hohlkörper verhindert das Versinken im Wasser. Der Wasserski wird manöverierfähig durch ein an der Lenkstange (4) angebrachtes Ruderblatt (5). Auf einem Sattel (6) sitzend betätigt der Skifaher die Tretkurbel. A3.1e Teile sind durch ineinanderstecken leicht montier-und demontiePbar. It is driven by a double-sided crank (2) and one on the Propeller attached to the drive shaft (3). A hollow body attached to the water ski prevents sinking in the water. The water ski becomes maneuverable through a rudder blade (5) attached to the handlebar (4). Sitting on a saddle (6) the skier operates the crank. A3.1e parts are easy to put together mountable and demountable. LeerseiteBlank page
