Description

Zur Fortbewegung von Ruderbooten sind Riemen gebräuchlich, welche sehr viele Nachteile aufweisen. Ein nicht geübter Ruderer hat bei großer Kraftanstrengung nur einen Teil seiner Kraft zur Fortbewegung seines Bootes ausgenutzt; entweder greift der Riemen zu tief in das Wasser, oder er berührt nur die Wasseroberfläche. Die Folge der ungleichmäßigen Bewegung ist ein ewiges Steuern und rasches Ermüden. Ferner ist der Rücken in der Fahrtrichtung; dadurch ist die Übersicht erschwert.For the movement of rowing boats, belts are used, which have many disadvantages. An inexperienced rower has great physical exertion only used part of his strength to move his boat; either If the belt is too deep in the water or it just touches the surface of the water. The consequence of the uneven movement is eternal steering and rapid fatigue. Furthermore, the back is in the direction of travel; this makes the overview more difficult.

Der Ruderapparat schaltet diese Nachteile aus und kann von jedem mühelos ohne besondere Kraftanstrengung bedient werden. Der Apparat ist aus Metall hergestellt und ist an jedem Ruderboot an Stelle der Riemen leicht anzubringen.The rowing machine eliminates these disadvantages and can easily be used by anyone can be operated without any particular physical exertion. The apparatus is made of metal and is easy to attach to any rowing boat in place of the straps.

Fig. i zeigt den Querschnitt eines Bootes a und Fig. a die Seitenansicht eines Bootes mit angebrachtem Apparat.Fig. I shows the cross section of a boat a and Fig. A the side view of a boat with attached apparatus.

Der Apparat besteht aus Rollen b, welche sich auf einer Laufschiene c hin und her bewegen. An jedem Apparat befindet sich eine verstellbare flossenartige Schaufel mit einem in einem Scharnier beweglichen Anschlag. Durch die am Apparat befindlichen Griffe wird der Apparat nach vorn gezogen, die Schaufeln greifen gleichmäßig in das Wasser ein und stoßen das Boot nach vorn. Durch eine Zugfeder f führt der Apparat durch automatisches Hochheben die Schaufel bis zum Anschlag zurück. Die Steuerung erzielt man durch einseitiges Betätigen der Schaufeln; werden beide Apparate in Tätigkeit gebracht, läuft das Boot geradeaus.The apparatus consists of rollers b, which are on a running rail c move back and forth. There is an adjustable fin-like on each device Shovel with a stop that can move in a hinge. By on the phone The handles are pulled forward and the shovels grip evenly into the water and push the boat forward. The leads through a tension spring f Apparatus by automatically lifting the shovel back as far as it will go. the Control is achieved by operating the blades on one side; become both devices When activated, the boat runs straight ahead.
