Abstract

The turbine has a vertical shaft with any number of radial arms. The arms extend across the shaft and project at both ends. Each arm carries a blade at each end. The blades can pivot about the arms. They swing so that on the driving sides of the rotation blade hangs vertically and catches the wind while on the return motion when it is travelling against the wind it is horizontal offers little resistance. The pairs of blades can be connected by canvas or cables so that they are always perpendicular to each other. The blades can be rectangular metal plates or canvas sheets held in aluminium frames. They can also be bucket type metal blades.

Description

- B e s c h r e i b u n g -- Description -

Die Erfindung soll dazu beitragen, die praktischen Möglichkeiten zur Ausnutzung der lEindenergie in größerem Umfang zu verbessern.The invention is intended to contribute to the practical possibilities for To improve the utilization of local energy to a greater extent.

Die z.Z. bekannten Windräder und Rotoren haben den Nachteit, daß sie in den blind gedreht werden müssen und keine wesent= liche Vervielfältigung der wirksamen Fäche zulassen.The currently known wind turbines and rotors have the disadvantage that they in which must be turned blind and no substantial duplication of the allow effective area.

Diesem Itangel wird durch das, auf vertikaler Achse drehende Segel abgeholfen. Einmal dadurch, Daß auf einer Ebene 2 bis 4 Segel wirksam werden können, zum andern dadurch, daß beliebig viele Segel übereinander angeordnet werden können. Dadurch ergibt sich eine grössere wirksame Gesammtfläche. Wenn 4 Segel in einer Ebene montiert sind, ist ein Segel immer wirksam, aus welcher Richtung der Wind auch kommt.This angel is made possible by the sail rotating on a vertical axis remedied. On the one hand by the fact that 2 to 4 sails can be effective on one level, on the other hand by the fact that any number of sails can be arranged one above the other. This results in a larger effective total area. When 4 sails in one When mounted on a level, a sail is always effective in whatever direction the wind is blowing also comes.

Grundgedanke der Erfindung ist, daß das Segel,durch den Wind, auf der dem Wind entgegendrehenden Seite , seine Form oder Lage so verändert, daß es dem Wind nur einen sehr geringen Widerstand entgegen setzt und dadurch ein beachtliches Drehmoment ersieht wird.The basic idea of the invention is that the sail, by the wind, on the side facing the wind, changes its shape or position so that it offers very little resistance to the wind and therefore a considerable one Torque is seen.

In den beigefügten Zeichnungen sie 3 von mehreren möglichen Formen skitziert, die dem Erfindungsgedanken gerecht werden und leicht zu realisieren sind.In the accompanying drawings you 3 of several possible forms sketches that do justice to the idea of the invention and are easy to implement.

Das Segel in Zeichnung 1 ist an einem dreieckigen Alurohr= rahmen mittels entsprechender Reißverschlüsse befestigt.The sail in drawing 1 is on a triangular aluminum tube frame attached by means of appropriate zippers.

Das hSterial ist Segeltuch.Dieser Alurahmen mit dem Segel, iBt an dem mit der vertikalen Achse fest verbundenen Ausle= ger montiert. Die Form des Segels ist, wie aud der Zeichnung ersichtlich so gewählt,daß das Segel den Winddruck voll auf= nehmen kann ohne einzuknicken. In der Mitte befindet sich ein Stabilisator a aus Alurohr an dem das Seil b befestigt ist,mit dem die Wirkung des Segels reduziert oder ganz auf= gehoben werden kann. Die Befestigung des Segels mittels Reißverschlüssen gestattet bei Beschädigung oder Zerstörung ein schnelleres Auswechseln des Segels.The hSterial is canvas. This aluminum frame with the sail is on mounted on the bracket that is firmly connected to the vertical axis. The shape of the As can be seen in the drawing, the sail is chosen so that the sail takes the wind pressure fully open = can take without buckling. There is a stabilizer in the middle a made of aluminum tube to which the rope b is attached, with which the effect of the sail is reduced or completely on = can be lifted. The attachment of the sail by means of zippers allows the sail to be replaced more quickly in the event of damage or destruction.

Zeichnung 2 stellt ein Segel mit rechteckigem Rahmen dar, daß im oberen Drittel auf einer gemeinsamen Achse c mit dem gegenüberliegenden Segel drehbar aufgehängt ist. Es ist so ausbalanziert, das es mit nur leichtem Übergewicht senkrecht hängt und in dieser Lage vom Ausleger begrenzt wird. Das dem Wind entgegendrehende Segel kann sich dadurch fast wagerecht legen.Drawing 2 shows a sail with a rectangular frame that in the upper Third rotatably suspended on a common axis c with the opposite sail is. It is balanced so that it hangs vertically with only a slight excess weight and is limited in this position by the boom. The sail turning against the wind can thus be almost horizontal place.

Die beiden, auf der gemeinsamen Achse c aufgehängten Segel a und b lassen sich aber auch durch Seilzug so arretieren,daß sie in einem Winkel von 90 ° auf der Achse c festsitzen. Dadurch wird das dem Wind entgegen drehende Segel b automatisch wagerecht gestellt, wenn Segel a durch den Winddruck senkrecht steht. Durch Seil= zug können auch beide Segel wagerecht gestellt werden und so außer Betrieb gestzt werden.The two sails a and b suspended on the common axis c but can also be locked by means of a cable pull so that they are at an angle of 90 ° sit tight on axis c. This causes the sail to turn against the wind b automatically placed horizontally when sail a is vertical due to the wind pressure. By pulling the rope, both sails can be set horizontally and thus out of service be set.

die 3. Form des Segels in Zeichnung 3 dargestellt, besteht aus 2 rechteckigen Teilen. Beide auf Alurohr gespannt. Der obere Teil ist am Ausleger befestigt, währent der untere Teil in den Gelenken a und b beweglich ist und sich dadurh auf der dem Wind entgegen drehenden Seite fast wagerecht legen kann. Die Regulierung und Stillsetzung erfolgt ebenfalls durch Seilzug.the 3rd shape of the sail shown in drawing 3 consists of 2 rectangular ones Share. Both stretched on aluminum tube. The upper part is attached to the boom, perpetually the lower part is movable in the joints a and b and is dadurh on the dem Wind against the turning side can be almost horizontal. The regulation and shutdown is also done by cable pull.
