Definitions

  • the present invention relates to an inflatable hull, which is more particularly but not exclusively intended for propulsion by sail, and a floating device, in particular of the dinghy type, comprising such an inflatable hull.
  • the first drawback of these known floating devices is linked to the fact that the rigidity of their inflatable hull is less than that of a known floating device with a hard material hull. Consequently, their ability to support the weight of one or more crew members and their ability to withstand the forces applied by the water and by the mast on the inflatable hull are limited or require the addition of bulky structural rigid reinforcements.
  • a second drawback of these known floating devices is the shape of the hull of their inflatable hull, which is flat. Consequently, their inflatable hull has poorer hydrodynamic performance and their behavior in navigation is of poorer quality than that of a known hull which has a hull of non-planar cross section, for example having a general U or V shape. , as well as a non-planar longitudinal section and a bow.
  • a third drawback of these known floating devices is the complexity of assembling the various pneumatic envelopes which make up their inflatable hull. Consequently, the time required for their manufacture, maintenance and possible repairs is long and this adversely affects production costs. In addition, the complexity inducing a consequent use of material, these inflatable hulls represent a relatively high weight. These drawbacks also affect in particular other inflatable hulls represented in the patents. JP2007176236 , FR2722758 , US2011036284 , which have a complex structure comprising a peripheral buoyancy tube to which are added a floor and a transom. Also, the latter originally intended for motor propulsion, do not have good nautical qualities when propelled by means of a sail because in addition to being relatively heavy, they do not have a good support on the water.
  • a fourth drawback of these known floating devices is the lack of structural rigidity of the assembly between the inflatable hull and the dinghy type equipment which does not allow the use of a sail of a power comparable to that which equips a dinghy in hard material. Consequently, their performance in navigation is lower than that of known dinghies with hulls made of hard material.
  • each of the inflatable envelopes constituting the bottom and the side tubes is produced by means of a double-walled material, the walls of which are connected to one another by a multitude of connecting wires.
  • the inflation with air is carried out in the space between the two walls retained by the threads.

  • the document US 2009/0031941 indicates moreover that by choosing the length of the wires which extend between the walls, it is possible to obtain inflatable compartments of any size and shape. Assuming that such a double-walled envelope with connecting threads of varying lengths was feasible, this would be a complex means of imparting a desired shape to the inflatable compartments.
  • Inflatable floating devices of the board type with manual paddle propulsion are also made of such double-walled materials.
  • the hull is devoid of any buoyancy elements attached to the casing, has a relatively flat bottom and has a front spatula, in other words a somewhat raised nose. Because of their flat bottom, these board type machines have a nautical behavior which limits them to this use of board.
  • the invention has, among other objects, to provide an inflatable hull which makes it possible to overcome the aforementioned drawbacks, that is to say an inflatable hull which is rigid in navigation without the need for a structure and capable of supporting weight and loads. consequent efforts, which can have a hull of the desired shape, and which is simple to make.

  • said envelope comprises on at least part of its periphery a lateral peripheral band having a shape determining said curvature in longitudinal section of said envelope.
  • said peripheral band comprises at least one transverse peripheral band having a shape determining the curvature in cross section of said envelope.
  • the inflatable hull according to the invention benefits from good hydrodynamic performance and quality navigation behavior.
  • the shape given to the side strip and to the transverse strip, which the double-walled casing is forced to follow in the inflated state thereof, constitutes a particularly simple means of imparting respectively to the longitudinal section and to the transverse section. of the hull the desired non-plane profile.
