Abstract

The device, in particular, as an aid to breast-stroke swimming comprises plastic holding rails which are joinable to the outer sides of swimmer's lower legs, and are provided with blades joined to the holding rails by hinges. The blades are arranged so that during the propulsive stroke of the legs they pivot outwards and thus increase the area contributing towards the propulsive force. At the end of the propulsive stroke they pivot back into their original position against the holding rails and remain there until the next propulsive stroke.

Description

Eine Mechanik soll, vorwiegend das Brustschwimmen, im Freizeit- Schnorchel- und Sportbereich, deutlich beschleunigen.Mechanics should, mainly breaststroke, in the leisure, snorkeling and sports area, accelerate significantly.

An den Beinen, im Besonderen an beiden Unterschenkeln, außen, sollen vier lamellenartige "Flossen", (ein bis acht Stück je Bein, je nach Testergebnissen) angelegt werden. Beim Gehen liegen sie am Bein an.On the legs, in particular on both lower legs, on the outside, there should be four lamella-like "Fins", (one to eight pieces per leg, depending on the test results). While walking they lie on the leg.

Beim Anziehen der Beine in der Schwimmsituation, liegen die Lamellen ebenfalls am Bein an. In der "Antriebsituation", bei Abstoßen der Beine, stellen sie sich durch den Wasserdruck, über scharnierartige Gelenkverbindungen(Material Kunststoffe oder Metalle, eventuell Weich-PVC) an den Halterungen, in einen Winkel von 90 Grad (wahlweise 60 bis 120 Grad, je nach Testergebnissen) zum Bein und erhöhen deutlich die Antriebskraft. Die Lamellen werden im optimalen Winkel von Stoppelementen gehalten. Die einzelnen Lamellen könnten unterschiedliche Winkel zum Bein aufweisen (Muss durch Tests ermittelt werden) Die Lamellen sind an der Unterkante, etwas nach außen gebogen. Dadurch öffnen sie sich beim Beinabstoß sofort durch den Wasserdruck. Beim Spreizen der Beine und beim Anziehen, legen sich die Lamellen, ebenfalls durch den Wasserdruck, wieder ans Bein an. Dabei legen sie sich, je nach Anzahl der Lamellen und dem Abstandsmaß zum Bein, eventuell schuppenartig übereinander. Das Material der Lamellen sollte Hart-PVC sein. Die seitlichen und unteren Kanten könnten in Weich-PVC gefertigt werden. Außerdem könnten Metalle, vorwiegend Leichtmetalle, eingesetzt werden. Die Lamellen sind an einer, senkrecht am Bein befestigten Halteschiene waagerecht zum Boden, (bei stehendem Schwimmer) mit Gelenkverbindungen, (wie oben beschrieben) angebracht. Die Gelenkverbindungen und damit auch die Lamellen, könnten auch, (abhängig von Testergebnissen) um bis zu 30 Grad aus der Waagerechten abgesenkt oder angehoben werden. Damit könnte eine günstigere Schwimmlage erreicht werden. Lamellen aus Hartschaum oder mit Hohlkammern versehen, könnten Auftrieb ermöglichen, falls dies erwünscht ist.When pulling on the legs in the swimming situation, the slats also rest on the leg. In the "drive situation", when the legs are pushed off, they are exposed to the water pressure hinge-like joint connections (material plastics or metals, possibly soft PVC) on the brackets, at an angle of 90 degrees (optionally 60 to 120 degrees, depending on Test results) to the leg and significantly increase the driving force. The slats are in the optimal angle held by stop elements. The individual slats could be different Have an angle to the leg (must be determined by tests) The slats are on the Lower edge, slightly curved outwards. As a result, they open immediately when the leg is pushed off Water pressure. When spreading the legs and tightening, the slats also lie down by the water pressure, back on the leg. They lie down depending on the number of slats and the distance to the leg, possibly one above the other like a scale. The material of the Slats should be hard PVC. The side and bottom edges could be in soft PVC are manufactured. In addition, metals, primarily light metals, could be used. The slats are attached to a support rail, which is attached to the leg vertically, horizontally to the floor, (with standing swimmer) with articulated connections, (as described above) attached. The Articulated connections and thus also the slats, could also (depending on test results) can be lowered or raised by up to 30 degrees from the horizontal. So that could more favorable swimming position can be achieved. Slats made of rigid foam or with hollow chambers provided, could provide buoyancy if desired.

Die Vorderkanten der Lamellen müssen leicht nach innen gebogen sein, dass sie beim Gehen im Wasser am Bein anliegen.The front edges of the slats must be slightly curved inwards so that when walking in the Apply water to the leg.

Die Größe, Form und Material, der Lamellen, (Kunststoffe, Metalle, glasfaserverstärktes Material) werden in Tests noch festgelegt.The size, shape and material of the slats, (plastics, metals, glass fiber reinforced material) are still determined in tests.

Die Halterung für die Gelenke, sollte aus mindesten einer senkrechten, beingeformten Kunststoffschiene (gegebenenfalls auch Metalle) bestehen. Bis zu acht beinumschließende Schienen sind möglich. Fall erforderlich telescop ähnlich ausziehbar, um sich den verschiedenen Beinlängen anzupassen. Diese Gelenkhalterung(en) wird, (werden)mit Bändern und Klettbänder, mit Schnallen oder Gumminoppen, die in Gummiösen gedrückt werden, am Bein befestigt. Ein Band unter die Fußsohle gelegt, verhindert das Hochrutschen des Gerätes. The bracket for the joints should consist of at least one vertical, molded Plastic rail (possibly also metals) exist. Up to eight encircling legs Rails are possible. If necessary, telescope similarly extendable to accommodate the different Adjust leg lengths. This hinge bracket (s) will be (will) with straps and Velcro, fastened to the leg with buckles or rubber knobs that are pressed into rubber eyelets. On Band placed under the sole of the foot prevents the device from slipping up.

Eine Alternative ist ein Gummistrumpf (Neoprenstrumpf oder anderes flexibles wassertaugliches Material) mit ein bis acht senkrechten Einlagen zum Befestigen der Gelenke, mit Fußteil. Der Strumpf könnte am Fuß und am Bein so stark durchbrochen sein, wie es die Festigkeit der Konstruktion erlaubt. Der Strumpf wird an seiner Innenseite mit einem senkrechten Reißverschluss oder Klettverschluss oder Schnallen, geschlossen.An alternative is a rubber stocking (neoprene stocking or other flexible water-compatible Material) with one to eight vertical inserts for fastening the joints, with foot section. The The stocking on the foot and leg could be broken as much as the firmness of the Construction allowed. The stocking is closed on the inside with a vertical zipper or Velcro or buckles, closed.

Eine einfache Ausführung, ist eine Lamelle, mit einer Bindung am Bein, einer senkrechten Halteschiene, von 10 bis 30 cm Länge und einem Sicherungsband unter dem Fuß. Die Lamelle kann in unterschiedlichen Höhen, am Bein angebracht werden.A simple version is a lamella, with a binding on the leg, a vertical one Holding rail, 10 to 30 cm in length and a safety strap under the foot. The slat can be attached to the leg at different heights.

Sinn der Erfindung ist, Kraft und Ausdauer der Beine, besser auszunutzen und Schnelligkeit beim Schwimmen, zu gewinnen.The purpose of the invention is to make better use of the strength and endurance of the legs and to be quick Swim, win.
