Description

Schwimmschuh mit löffelförmiger Klappflosse nach Patent 484882 Die an sich bekannten klappbaren Schwimmflossen tragen nach dem Zusatzpatent 510 388 eine zur Schwenkachse der Flosse parallel verlaufende Rippenwand a. Diese Rippenwand ermöglicht erstens infolge erhöhter Stabilität der Flossen zu deren Herstellung die Verwendung dünnsten Leichtmetallbleches, zweitens bewirkt die Rippenwand beim Schwimmstoße ein rasches Aufklappen der Flossen. Da der seitliche Wasserdruck gegen die Rippenwand beim Schwimmstoße bzw. Anschlag des Flossen- oder Schwingenkopfes an das Fußband mit kräftigem Stoße wirkt, empfiehlt es sich, die Rippenwand an mehreren Stellen mit den Flossenrändern zu versteifen. Auch beim Sitzen des Schwimmers am Strande oder bei unbeabsichtigtem Anstoße der Flossen gegen ein Bein während des Schwimmens kann die Rippenwand oder die Kante der dünnwandigen Flosse aus ihrer Lage abgebogen werden. Um eine Beschädigung der Rippenwand oder der Flosse zu verhüten, sind zur Erhöhung deren Stabilität mehrere die Flossenwände mit der Rippenwand a verbindende leichte Querstege b angeordnet.Swimming shoe with a spoon-shaped folding fin according to patent 484882 The foldable swimming fins known per se carry, according to the additional patent 510 388, a rib wall a running parallel to the pivot axis of the fin. Due to the increased stability of the fins, this rib wall enables the use of the thinnest light metal sheet for their production, and secondly, the rib wall causes the fins to open quickly during swimming strokes. Since the lateral water pressure against the rib wall during swimming strokes or when the fin or swing head hits the ankle strap with a strong impact, it is advisable to stiffen the rib wall in several places with the fin edges. The rib wall or the edge of the thin-walled fin can also be bent out of its position when the swimmer is sitting on the beach or if the fins accidentally bump into a leg while swimming. In order to prevent damage to the rib wall or the fin, several light transverse webs b connecting the fin walls to the rib wall a are arranged to increase their stability.
