Abstract

The flipper has a fin plate (1) and a foot plate (2) of carbon-fibre reinforced plastics with rubber layer and two arms to hold different sized fins. The foot plate (2) has a U or V-shaped geometry to transfer positive bending and torsional properties to the foot plate. The rubber layer (3) guards against friction on the plate. The foot plate is designed to fit into a rubber foot shoe.

Description

Teilbare Taucherflossen üblicher Bauart sind bekannt als Konstruktionen mit gesamtem Schuhteil (ohne Fußblatt) und Flossenblatt. Hierbei ist das Schuhteil so konstruiert, dass eine Verbindung zum Flossenblatt über ein Verbindungssystem erfolgt, das annähernd linearen Belastungen ausgesetzt wird: hieraus resultiert ein unvorteilhaftes Biegeverhalten sowie eine erhöhte Bruchgefahr der Füge- bzw. Verbindungsstelle zwischen den teilbaren Bereichen. Zu solchen Konstruktionen laufen folgende Patente (bzw. deren Anmeldungen): EP 1 127 590 A1 ; US 3 302 222 A ; US 3 521 312 A ; US 3 178 738 A ; FR 2 543 004 A; EP 0 310 828 A ; FR 2 410 488 A; BE 669 779 A; FR 1 208 636 A; DE 1 075 997 B .Divisible diving fins of a conventional design are known as constructions with an entire shoe part (without a base plate) and fin blade. Here, the shoe part is constructed in such a way that a connection to the fin blade is made via a connection system that is exposed to approximately linear loads: this results in unfavorable bending behavior and an increased risk of breakage at the joint or connection point between the divisible areas. The following patents (or their applications) are pending for such constructions: EP 1 127 590 A1 ; US 3 302 222 A ; US 3,521,312 A. ; US 3 178 738 A ; FR 2 543 004 A; EP 0 310 828 A ; FR 2 410 488 A; BE 669 779 A; FR 1 208 636 A; DE 1 075 997 B ,

Die Lösung des beschriebenen Problems liegt in der in Schutzanspruch (1) beschriebenen Konstruktion des Fußblatts [1,2] für teilbare Taucherflossen. Die in Anspruch (1) aufgeführten Merkmale machen die technischen Verbesserungen aus.The solution to the problem described lies in the construction of the footplate described in protection claim (1) [ 1 . 2 ] for divisible diving fins. The features listed in claim (1) make up the technical improvements.

Mit der Erfindung wird erreicht, dass Biegeeigenschaften und Torsionseigenschaften durch Geometrie und Werkstoffeinsatz verbessert bzw. optimiert werden. Der Taucher erreicht somit mehr Vorschub bei gleichem Krafteinsatz. Die Produktlebensdauer wird ferner durch Geometrie und Werkstoff (zurückzuführen auf ermüdungsfreien Werkstoff CFK) gegenüber üblichen, thermoplastischen Kunststoffen verlängert.With the invention it is achieved that bending properties and torsional properties through geometry and use of materials can be improved or optimized. The diver thus achieves more feed with the same amount of force. The product lifespan is also due to geometry and material (attributable to fatigue-free CFRP material) compared to conventional thermoplastic materials extended.

Der Gummi-Layer wird als Dämpfungslage genutzt und minimiert bzw. eliminiert die Reibung zwischen Fuß- und Flossenblatt.The rubber layer is used as a cushioning layer and minimizes or eliminates the friction between the foot and fin blade.

Die Details der Erfindung „Fußblatt aus CFK (Kohlenstoff-faserverstärkter Kunststoff) mit Gummi-Layer für teilbare Taucherflossen werden anhand der 1 bis 4 erläutert.The details of the invention “CFRP (carbon fiber reinforced plastic) foot sheet with rubber layer for divisible diving fins are shown in FIG 1 to 4 explained.
