Definitions

  • the invention relates to an inflatable float, for example, for a catamaran, a rigid inflatable boat or a floating mattress.
  • Conventional forms of floats formed essentially by inflating a flexible sheath are circular cylinders or elongate, flat bodies having the cross-sectional shape of a flat oval.

  • the transition surface between the lateral surface and rear surface of the spatial structure of flat sheets is sharp-edged, which is aerodynamically advantageous.
  • a disadvantage of the float are the large cost of materials, the great weight and the bulkiness when folded state.

  • the boat body has a flat, approximately vertical rear wall, at the below the waterline edges, the lateral surface of the boat body is slightly extended backwards and then ends abruptly, so that behind a sharp break is formed.
  • the US 4942838 A shows a rigid hull inflatable boat, which laterally each has a longitudinal, elongated float, which at the rear end in a bulged circular End face ends.
  • the lower region of the two faces is connected by a flat rigid part, which is aligned parallel to the adjacent bottom surfaces of the boat and ends abruptly at the rear, so that a sharp break is formed.
  • the US 3955229 A discloses a rigid inflatable boat, each of which has a longitudinally extending, elongated float since ⁇ Lich. At the rear end, a rigid lid is fitted into each float, and connected to the flexible envelope surface, so ⁇ an abrupt termination between the lateral surface and the rear end face of the float is formed.
  • a floating body consists of an enveloping body formed by inflation of an envelope and an additional part which is glued under the waterline at the rearwardly tapering rear of the envelope outside ,

Abstract

L'invention concerne un flotteur que l'on fait avancer dans l'eau dans son utilisation normale, lequel comprend un corps formant enveloppe gonflable 1, 11 et une pièce supplémentaire 2, 12, 22, 32 qui est collée extérieurement à la partie arrière inférieure du corps formant enveloppe. La pièce supplémentaire prolonge la surface latérale du corps formant enveloppe tangentiellement et vers l'arrière et, à un bord 2.2, 12.2, 22.2, 32.2, elle forme une surface arrière du flotteur. La configuration de ce bord permet de réduire l'effet de freinage par aspiration dans l'eau, comparativement à un raccordement arrondi entre la surface latérale et la surface arrière.
