Abstract

The surfboard is without sails, and is for training purposes. An engine with drive propellor is located in the centre of gravity of the board. The drive energy is regulated by compression of a footpedal. Reduction of the pressure on the pedal switches-off the engine. The propellor is located in an intake and pressure channel.

Description

Bei dieser Erfindung handelt es sich um eine Neuerung gemäß dem Ober­ begriff des Anspruches 1.This invention is an innovation according to the Ober Concept of claim 1.

Am Wellensurfen - nicht Segelsurfen - interessierte Neulinge stehen vor dem Problem, sich auf diese Sportart vorzubereiten - diese Sportart zu trainieren - bevor sie auf geeigneten Revieren das Wellen­ surfen durchführen können. Ein Training mit dem Segelsurfbrett ist un­ geeignet, weil später auf dem Wellensurfbrett das Segel fehlt, wodurch auf dem Segelsurfbrett das Balancehalten erleichtert wird. Geeigneter ist hierfür ein Skateboard an Land. Dieses Trainingsgerät ist jedoch gerade für Erwachsene mitunter äußerst gefährlich wegen der unvermeid­ lichen Stürze auf hartem Boden. Vor dem gleichen Problem stehen Ski­ läufer, die Skiboarde laufen wollen. Um sich trotzdem auf das Wellen­ surfen und Skiboardfahren vorzubereiten, ist also ein anderes Trai­ ningsgerät erforderlich und zwar eines, das im Wasser einsetzbar ist.Interested newbies are at wave surfing - not sailing surfing faced with the problem of preparing for this sport - this Sport to train - before surfing on suitable areas can do surfing. Training with the sailing surfboard is un suitable because later the sail is missing on the wave surfboard, so balancing is made easier on the sailing surfboard. More suitable is a skateboard on land for this. However, this training device is especially dangerous for adults because of the inevitable falls on hard ground. Skis face the same problem runners who want to run Skiboarde. To focus on the waves anyway Surfing and preparing for ski boarding is a different experience ningsgerät required and one that can be used in water.

Aufgabe der Erfindung ist die Schaffung eines geeigneten Trainingsge­ rätes für den Einsatz im Wasser. Im Folgenden wird dieses Trainingsge­ rät näher beschrieben.The object of the invention is to create a suitable training gene advises for use in water. In the following this training ge advises described in more detail.

Fig. 1 zeigt das Gerät im Längsschnitt und Fig. 2 im Querschnitt. Das Gerät besteht aus einem Surfboard in solch einer Größe, daß es eine Person tragen kann, ohne zu sinken. Im Schwerpunkt des Surfboardes ist ein Benzinmotor oder Elektromotor 2 in das Surfboard eingelassen, der einen Antriebspropeller 3 antreibt, der in einem Kanal 4 untergebracht ist, der vorne und hinten offen ist, so daß bei laufendem Motor vorne Wasser durch den Propeller angesaugt und hinten ausgestoßen wird. Fig. 1 shows the device in longitudinal section and Fig. 2 in cross section. The device consists of a surfboard of such a size that a person can carry it without sinking. In the center of gravity of the surfboard, a petrol engine or electric motor 2 is embedded in the surfboard, which drives a drive propeller 3 , which is accommodated in a channel 4, which is open at the front and rear, so that water is drawn in through the propeller at the front and expelled at the rear when the engine is running becomes.

Es entsteht ein Jeteffekt, durch den das Surfboard vorwärts bewegt wird ohne, daß der Propeller den Fahrer verletzen kann. Auf dem Surf­ board befindet sich ein Fußpedal 5, das durch Hinunterdrücken mit den Füßen als Gaspedal für den Antrieb des Motors wirkt. Fällt der Fahrer ins Wasser, so wird das Gaspedal 5 freigegeben und der Motor bleibt stehen.The result is a jet effect that moves the surfboard forward without the propeller injuring the driver. On the surf board there is a foot pedal 5 , which acts as an accelerator pedal for driving the motor by pressing down with the feet. If the driver falls into the water, the accelerator pedal 5 is released and the engine stops.

Der Fahrer steht freihändig auf dem Surfboard und steuert es während der Fahrt durch Gewichtsverlagerung.The driver stands hands-free on the surfboard and controls it during driving through weight shift.

Claims (3)
