Abstract (en)
[origin: WO9304740A1] Described are flippers (1) for divers or swimmers, the flat flipper fore-part being formed by a foil section (7) round which the water can flow freely. The flipper fore-part always makes a positive angle to the direction of flow of the water resulting from the forwards motion of the swimmer and flipper movement, during both the upwards (II) and downwards (I) kick of the flipper. In order to increase the propulsive effect of the flippers, while at the same time giving the diver or swimmer greater freedom of movement, the foil section (7) is located behind the diver's or swimmer's foot (11) in the direction of swimming and, during both the upwards (II) and downwards (I) kick of the flipper, is always in the flow of water past the underside of the swimmer's foot (11).
