Description

Kraftmesser an Ruderbooten Bei den bisher bekannten Ruderleistungsprüfvorrichtungen wird die Messung der aufgewandten Kräfte teils am Ruderblatt, teils am Bootskörper durch Messung des Wasserdruckes vorgenommen.Force gauge on rowing boats With the previously known rowing performance test devices the measurement of the applied forces is partly on the rudder blade, partly on the hull made by measuring the water pressure.

Einwandfreie Resultate können bei diesen Methoden nicht erzielt werden, weil das Ruderblatt im Wasser, je nachdem wie man es einsetzt, veränderliche Druckpunkte findet und weil der Strömungsdruck des Wassers am Bootskörper ebenfalls allerlei Nebeneinflüssen unterliegt.Flawless results cannot be achieved with these methods, because the rudder blade in the water, depending on how you use it, has variable pressure points finds and because the flow pressure of the water on the boat hull also all sorts Subject to secondary influences.

Der einzige feste Punkt, auf welchen die Kraft immer gleichmäßig wirkt, befindet sich an der Anlage des Ruderschaftes am Bootskörper. Deshalb kann auch nur hier eine einwandfreie Kraftmessung stattfinden.The only fixed point on which the force always acts evenly, is located on the rudder stock on the hull. Therefore also can only here can a perfect force measurement take place.

Aus diesem Grunde ist der Kraftmesser vorliegender Erfindung direkt in der das Ruder führenden Dolle angebracht. Er nimmt somit jeden Druck auf, der zur Fortbewegung des Bootes führt und registriert sowohl den Kraftaufwand als auch den Weg, den der Hebelarm des Ruders, an dem die Muskelkraft des Armes unmittelbar angreift, beim Durchholen zurücklegt.For this reason, the dynamometer of the present invention is straightforward mounted in the oarlock leading the oar. He thus takes on any pressure that leads to the movement of the boat and registers both the expenditure of force and the path taken by the lever arm of the oar on which the muscle power of the arm is directly attacks, backs up while overtaking.

Um dieses zu ermöglichen, besitzt die als Kraftmesser gebaute Anlage des Ruderschaftes am Boote eine bewegliche Hülse oder Schale i, in der das Ruder ruht. Dieselbe ist durch die im Befestigungspunkt drehbare Anlage (Dolle) 2 geführt und wird durch den Druck einer Feder g festgehalten. Ein Registrierstift q. zeichnet die durch den Ruderdruck hervorgerufene Verschiebung der Schale i in der Anlage 2 auf einen Registrierstreifen 5, sobald durch Zug am Holmen des Ruders das im Wasser eingetauchte Blatt einen Druck auf den Bootskörper ausübt. Die Federwirkung bewirkt bei nachlassendem Druck, daß die Schale i wieder in die auf der Abbildung dargestellte Ruhestellung zurückgleitet.To make this possible, the system built as a dynamometer has the rudder stock on the boat a movable sleeve or shell i, in which the rudder rests. The same is passed through the system (oarlock) 2, which can be rotated at the fastening point and is held in place by the pressure of a spring g. A registration pen q. draws the displacement of the shell i in the system caused by the rudder pressure 2 on a recording strip 5, as soon as it is in the water by pulling on the handlebars of the rudder submerged blade exerts pressure on the hull. The spring effect causes when the pressure drops, that the shell i returns to the one shown in the illustration Rest position slides back.

Bei der Ruderbewegung beschreibt außerdem jedes Ruder um die Anlage 2 einen Teilkreis. Mittels des Zahnrades 6, das auf der Welle 7 sitzt, welche den Registrierstreifen 5 trägt, bewirkt jede Drehung der Schale i bzw. der Anlage 2 einen entsprechend großen Vorschub. je größer die Schwingung des Ruders ausgeführt wird, desto größer wird der Teilkreis und der Vorschub, welcher die Abwicklung des Registrierstreifens bewirkt. Damit wird ein Diagramm erzeugt, das in der Tiefe den Kräftedruck und in der Länge den Weg des Ruders bezeichnet.In the rowing movement, each oar also describes the system 2 a pitch circle. By means of the gear 6, which sits on the shaft 7, which the Carries registration strips 5, causes each rotation of the tray i or the system 2 a correspondingly large feed. the greater the oscillation of the rudder executed becomes, the larger the pitch circle and the feed, which the development of the Registration strip causes. This creates a diagram that shows in depth the Pressure of force and the length of the path of the rudder.

PATENTANSPRUCH: Kraftmesser an Ruderbooten, dadurch gekennzeichnet, daß eine in der Dolle unter Federdruck sitzende Schale zur Aufnahme des Ruders und zur übertragung der beim Rudern aufgewandten Kraft auf eine Registriervorrichtung dient, deren Registrierband durch die beim Durchholen des Ruders erfolgende Drehung der Dolle eine in einer Richtung fortlaufende Verschiebung proportional dem vom Ruder zurückgelegten Weg erfährt.PATENT CLAIM: Force gauge on row boats, characterized in that that a shell seated in the oarlock under spring pressure to accommodate the oar and to transfer the force used during rowing to a registration device serves, whose registration band is caused by the rotation that takes place when the oar is swept through the oarlock has a continuous displacement in one direction proportional to that of the Rudder learns the distance covered.
