Bei der hier beschriebenen Erfindung ist davon ausgegangen worden, besonders in bezug auf Elastizität den tierischen Schwimmflossen möglichst nahe zu kommen, weshalb als Baustoff z. B. Gummi gewählt wurde.In the invention described here, it has been assumed, particularly in relation to to get as close as possible to the elasticity of the animal flippers, which is why z. B. rubber was chosen.

In der Zeichnung ist α die Sohle der Schwimmklappensandale, welche mit Hilfe breiter Schlaufen und Schnallen b am Fuße befestigt wird. Der ■ Flossenkörper c besteht aus einer Gummiplatte, welche in der Fußlängenachse unterhalb der Sohle bei d befestigt ist und an dieser Stelle im Querschnitt durch entsprechende Aussparung derartig verringert ist, daß sie sich bei Schwimmoder Tretbewegungen des Beines in zwei Flossenhälften leicht auf und ab bewegen kann. Die beiden Flossenhälften sind im übrigen Querschnitt nach den Regeln der Biegefestigkeit unter Berücksichtigung des in der Pfeilrichtung wirkenden Wasserdruckes bemessen und an der gegen das Wasser gerichteten Stoßseite mit entsprechenden Webstoff ein- oder -auflagen/ versehen. Die Aufklapp stellung wird dadurch begrenzt, daß die Flossenhälften bei e einen Ausschlag haben.In the drawing, α is the sole of the swimming flap sandal, which is attached to the foot with the help of wide loops and buckles b. The ■ fin body c consists of a rubber plate, which is attached in the foot length axis below the sole at d and at this point is reduced in cross section by a corresponding recess so that it can easily move up and down in two halves of the fin when swimming or pedaling the leg . In the rest of the cross-section, the two halves of the fins are dimensioned according to the rules of flexural strength, taking into account the water pressure acting in the direction of the arrow, and are provided with appropriate woven fabric on the joint side facing the water. The opening position is limited by the fact that the fin halves have a deflection at e.
