Description

Hohlruder Das Hauptpatent bezieht sich auf ein Hohlruder, bei dem der Abstand der aus vollem Material hergestellten Zug- und Druckfaser des kastenförmigen Holmes durch dünne Materialstreifen hergestellt ist.Hollow rudder The main patent relates to a hollow rudder in which the distance between the tensile and compression fibers of the box-shaped one made of solid material Holmes is made by thin strips of material.

Die Erfindung besteht darin, daß die Zug- und Druckfaser und die Materialstreifen sowie die Deckplatten des Ruderblattes aus Kunststoff hergestellt werden. Im Zuge der Entwicklung werden Gegenstände, die bisher aus organischen Stoffen hergestelltwurden, durch chemische, sogenannte Kunststoffe, ersetzt. Die gleichmäßige Beschaffenheit dieser Stoffe läßt eine genauere Berechnung der tragenden Teile des Ruders zu, als wenn sie aus Holz gemacht werden. Das Ruder wird daher aus Kunststoff leichter.The invention consists in that the tensile and compression fibers and the strips of material and the cover plates of the rudder blade are made of plastic. In the course of the development of objects that were previously made from organic materials, replaced by chemical so-called plastics. The uniform texture this material allows a more precise calculation of the load-bearing parts of the rudder than when they are made of wood. The plastic rudder is therefore lighter.

Es sind bereits Ruder aus Kunststoff" bekannt, die zur fabrikmäßigen Herstellung aus zwei Hohlformen bestehen, die durch luftleer machen der Hohlräume zusammengepreßt und verleimt werden. Diese Ruder sind aber nicht leichter, da eine in der Symmetrieebene liegende Rippe vorgesehen ist.There are already oars made of plastic "known that are used in the factory Manufactured from two hollow molds consist that by evacuating the cavities are pressed together and glued. But these oars are not lighter because a rib lying in the plane of symmetry is provided.
