Definitions

  • the present invention relates generally to trimarans, that is to say sailboats, in practice of the dinghy type, comprising a central hull and two lateral floats, with a connecting structure between said floats and said central hull.
  • trimarans which, relatively light, are intended to constitute objects of leisure along the shores, while requiring for their practice, on the part of their users, certain sporting qualities and a determined physical commitment .
  • the present invention generally relates to a trimaran, which, by its transport and storage facilities, is precisely advantageously capable of satisfying the demand of these potential users.
  • This trimaran which is therefore of the type comprising, in particular, a central hull, two lateral floats each disposed respectively on either side of the central hull, and a connecting structure connecting said lateral floats to said central hull, is d '' generally characterized in that, detachable from the central hull and lateral floats, the connecting structure is capable of forming by inversion a cradle suitable for confining said central hull and said lateral floats, for example for their transport on the roof of a car and / or for their storage.
  • the trimaran connecting structure preferably comprises two connecting arms, each adapted to be detachably secured at their ends, and parallel to each other, to the lateral floats, at least one, and in practice two, crosspieces, for securing to one another said link arms, and two legs, which, each carried respectively by said link arms, are each adapted to be joined detachable from the central shell.
  • the crosspieces are demountable, which further facilitates storage out of season for the assembly.
  • each of the link arms has in practice an inverted U configuration, with a middle part carrying the associated base and two legs specific to its connection to the lateral floats, and, having regard to said base, its said part median, which participates in the constitution of a floor, extends widely above the deck of the central hull.
  • the user of the trimaran according to the invention advantageously benefits from 'a relatively comfortable position.
  • the trimaran connecting structure according to the invention protects advantageously under it, between this central hull and the lateral floats, a passage sufficient for the wave, without necessarily interfering with it.
  • the trimaran according to the invention is advantageously capable of simple construction, and therefore economical, of reduced maintenance, and, usable alone or with two team members, without too prolonged learning, it offers great stability of navigation and is capable of performance, particularly of speeds, particularly high compared to comparable dinghies already existing to date.
  • the trimaran comprises, in the usual manner, a central hull 10, two lateral floats 11 each arranged respectively on either side of the central hull 10, a connecting structure 12 connecting said lateral floats 11 to said central hull 10, and a wing 13.
  • this central shell is equipped with a retractable fin 19, (FIG. 9), and that , capable of being produced for example by molding any suitable synthetic material, with, locally, metal inserts for the various fixing or joining points to be provided, it preferably has a shape of hull suitable for allowing effects of "planning" and a quick tack.
  • lateral floats 11 are preferably established so as to be submersible, in order to reduce the forces on the connecting structure 12 and allow easy reversal of the sailboat in case of "desalting".
  • the connecting structure 12 is suitable, as will appear below, to form, by inversion, a cradle suitable for the confinement of said central hull 1 0 and said lateral floats 11, for example for their transport on the roof of a car and / or for their storage.
  • this struc connecting structure 12 comprises two connecting arms 14, each adapted to be detachably secured at their ends, and parallel to one another, to the lateral floats 11, at least one cross member 15, and in practice two of such crosspieces 15, for securing to one another said link arms 14, and two legs 16, which, each carried respectively by said link arms 14, are each adapted to be secured to detachable from the central shell 10.
  • the various elements thus constituting the connecting structure 12 are for example tubular elements.
  • They are preferably metallic, for example aluminum.
  • Each of the link arms 14 has an inverted U configuration, with a middle part 17 carrying the associated base 16, and two legs 18 specific to its connection to the lateral floats 11, FIG. 3.
  • the middle part 17 of such a link arm 14 which, as will appear below, participates in the constitution of a floor 20, extends largely above the bridge 21, or upper surface, of the central shell. trale 10, figure 9.
  • the height of a base 16 from the middle part 17 of the link arm 14 which carries it is greater than that of the legs 18 of this link arm 17, so that, overall, the lateral floats 11 s extend halfway between the floor 20 of the assembly and the central shell 10.
  • Each of these lateral floats 11 comprises, locally, spaced from one another along its axis of elongation, two wells 23, each suitable for engaging, by simple interlocking, the end of the leg 18 concerned of the arm connecting link 14, and blocking in position thereof.
  • Such a well 23 which is preferably metallic, forms an insert for the float 11 which carries it, and, of course, for sealing it, it is blind.
  • this is a section of tube which, complementary to the legs 18 of the connecting arms 14, is closed at its internal end.
  • the legs 16 are permanently fixed to the connecting arms 14, for example by welding.
  • each of these legs 16 has a trapezoidal configuration, with its small base 25 on the side of the central shell 10, for attachment thereto.
  • the central shell 10 has locally at least two projections 26 suitable for framing the part of such a base 16, namely its small base 25, which bears on it.
  • each of the cradles 27 which they form is provided a bore 28 which gives access to a threaded insert 29 for cooperation with a screw 30 suitable for the desired attachment of such a base 16 to the central shell 10, such shown schematically in broken lines in Figure 4.
  • the insert 29 which, for sealing the assembly, is blind, is forcibly engaged in a plate 32 itself forming an insert within the corresponding wall of the central shell 10.
  • the cross members 15, which extend substantially perpendicular to the connecting arms 14, are established from one of the legs 16 to the other.
  • each of the crosspieces 15 is detachably secured to the legs 16.
  • such a cross member 15 comprises, at each of its ends, a half-shell 34, which is suitably attached to it, for example by welding, generally transversely to its direction of elongation, and by which it can be applied, and secured by screwing, using screw 35-nut 36 assemblies, to the concerned portion of a base 16.
  • each of the half-shells 34 is therefore complementary, in section, to such a leg 37.
  • two screw 35-nut assemblies 36 are sufficient for fixing a cross-member 15, at each of the ends thereof.
  • cross members 15 thus extend below the floor 20 of the assembly, between the latter and the central shell 10.
  • this floor 20 is simply constituted by two fabrics 38 stretched, parallel to one another, from one of the connecting arms 14 to the other, at the ends of these, the sleepers 15 are not a nuisance for a user if the latter, seated on such a fabric 38, causes its weight to deform it.
  • the connecting structure 12 thus formed has great rigidity, and therefore great strength.
  • this hardware comprises, in particular, a lifting rudder 39, FIG. 1.
  • the wing 13 comprises a large battened sail 40, which. is engaged on a mast 41, in two parts, and to which it is possibly added a jib 42, as shown.
  • the mast 41 which is suitably guyed, is simply seated on the central shell 10, with its foot engaged in a shallow bowl 43 provided for this purpose recessed on the deck 21 of this central shell 10.
  • two bowls 43 are thus provided, at a distance from one another, on the deck 21 of the central shell 10, along the axis of elongation thereof, one to be used when jib 42 is used, the other to be used in the absence of such a jib, FIG. 8.
  • the mainsail 40 is equipped, for its engagement on the mast 41, with a sheath 44, which, relatively wide and triangular, facilitates the passage of the air streams, all happening as if the mat 41 thus presented, in section, an elongated profile, FIGS. 1, 6, 7.
  • each of the slats 45 with which this large sail 40 is fitted does not stop at the seam 46 thereof delimiting its sheath 44.
  • the trimaran according to the invention proves to be particularly fast, its geometry allowing it to navigate in balance on the central hull, as shown in FIG. 9, which is a speed factor.
  • the connecting structure 12 can advantageously be used for transporting the central shell 10 and the lateral floats 11, and / or for storing them.
  • this connecting structure 12 On the gallery 50 of any automobile 51, as shown diagrammatically in FIG. 10.
  • the connecting structure 12 By the legs 18 of its connecting arms 14 as well as by its legs 16, the connecting structure 12 according to the invention then constitutes, for the central shell 10 and the side floats 11, suitably placed side by side on its sleepers 15, a cradle suitable for proper containment of this central hull 10 and these lateral floats 11.
  • the transport and / or storage of the mast which is in two parts, does not pose any particular problem, this mast being able, for example, to be superimposed on the central hull as well. to the side floats during this transport and / or this storage if desired.
