Definitions

  • the present invention relates to boats of the pleasure craft type, and more particularly to the sailing type boats such as, for example, trimarans.
  • the present invention therefore aims to achieve a structure of the sailing type boat, like a trimaran, offering very interesting sporting performance while having a very simple design allowing easy transport, disassembly and reassembly very easy.
  • This structure because of its qualities, makes it possible to arrive at a cost price very much lower than that of boats having or being able to have comparable performances.
  • the subject of the present invention is a boat structure according to the preamble of claim 1 comprising an oblong central body, two floats, two lateral longitudinal arms, one of their ends of which is secured to said body by first fixing means and second and third means for connecting the two other ends of said arms with the two said floats respectively.
  • a boat having a structure of this type has in particular been described in patent GB-A-922,065 (Welman).
  • the boat structure according to the invention and in accordance with the characterizing part of claim 1 is characterized by the fact that said body consists of a beam comprising two parts abutted to one another along a junction surface, a first part relatively short in shape substantially in an arc having a first value of curvature R1, a second part longer than ⁇ the first part, in shape substantially in an arc having a second value R2 of radius of curvature significantly greater than the first value R1.
  • said structure is also characterized in that the two said arms consist of a curved rod situated in a first plane substantially perpendicular to a second plane containing said beam, said first plane passing in the vicinity of said junction surface of the two said parts, the lengths of the two parts of said rod located on either side of said second plane being substantially equal, these two said parts of said rod constituting the two said arms.
  • said structure is also characterized by the fact that it comprises a mast carrier pivoting in said second plane around an axis located substantially near said rod and means for blocking said carrier. mast in a determined position with respect to said beam.
  • said structure is also characterized by the fact that said floats are constituted by a first body comprising at least one substantially cylindrical middle portion of revolution, a sleeve located on said middle portion of section substantially complementary to that of said middle portion, so as to be able to pivot around this middle portion, drift means mounted in cooperation with said sleeve and means for controlling the pivoting of said sleeve.
  • said structure is characterized in that it comprises, in association with at least one of said oblong central body and two arms, predisposed means for hooking navigation elements and at least one navigation element cooperating with said attachment means.
  • FIGS. 1 and 2 represent, in two different views, one in perspective slightly from the side and the other from above, an embodiment of a boat structure of the trimaran type, comprising a central body 1 bordered on either side by two floats 2 and 3. These two floats are connected to the central body 1, respectively by two arms 4 and 5 which are secured at one point on the two floats 2 and 3 and by connecting means on the central body 1.
  • a mast holder 6 in which is able to position a mast 7 for supporting at least one sail 8 which can be tensioned, by example by handle means 9, such as the element known under the term of wishbone.
  • tensioners 10 and 11 which make it possible to give them the necessary rigidity, while nevertheless leaving them a certain flexibility in order to be able to absorb the forces or the shocks which they will undergo when such a boat is called. to move on the liquid element.
  • the two floats 2 and 3 can be associated respectively with drift means 13 and 14.
  • This central body 1 is essentially constituted by a longitudinal beam 20 comprising at least two parts 21 and 22. These two parts 21 and 22 are abutted according to a first junction surface substantially defined at 23. These two parts 21 and 22 substantially affect the shape of a circular arc, the first part 21 of which has a radius of curvature, for example R1, having a certain relatively small value, while the second part 22, also having the general shape of a circular arc, has a radius curvature R2 whose value is significantly greater than the value of R1 defined above.
  • R1 radius of curvature
  • This central body is intended to constitute a part of the structure allowing a certain flotation.
  • the beam is advantageously tubular and of circular, oval or triangular section and is closed at both ends to allow it to float.
  • the buoyancy appears in relation to a level 24 of the water over which such a boat structure is able to move.
  • end 25 of the second longest part of the two parts forming the beam possibly includes a rudder 26 pivotally mounted at this end 25.
  • a rudder 26 pivotally mounted at this end 25. This can be optionally maneuvered by any arm element as schematically illustrated in 27.
  • a traction cable 30 allowing to exert at each end a certain force .
  • This cable 30 can be connected by a plurality of sub-tensioners such as 31 and 32 distributed over the length of the beam, to allow a certain rigidity to be obtained over the length of this cable 30 and to prevent it from being able to deform or get out of his plan.
  • the first part 21 having the smallest radius of curvature R1 will constitute the bow or the bow of the boat, while the longest part will in fact constitute the bow which will be more or less in contact with the surface 24 of the water as a function of the speed reached by the boat.
  • the latter at high speed, will only take support on the water through its floats 2 and 3.
  • a mast-carrying element 40 pivotally mounted about an axis 41 advantageously perpendicular to the plane in which the curved axis of the beam 20 is contained.
  • the support bearings of this axis 41 are positioned relative to the beam 20 by means, for example, of two spacers 42, 43, forming a trestle to allow this mast-carrying element 40 to be able to pivot around this axis 41 which must remain in position relatively fixed with respect to the beam 20.
  • the rotation of this mast carrier 40 as described above obviously has the advantage of making it possible to place the mast 7 in cooperation with the other elements of the structure, in a very easy. Straightening by rotation of the latter to its nor position male is then much easier, without the use of this boat requiring the help of outside help.
  • this mast-carrying element must include means for blocking its end 44 relative to the beam 20, so that, when the mast is positioned in the mast-carrying element 40, as illustrated in FIG. 3A , it is in the normal position that a mast should have in relation to such a type of boat.
  • These locking means 44 are simply illustrated, in particular in FIG. 3B, by a pawl 46 which can cooperate with a corresponding notch 47 produced in the end 44 of the mast-carrying element 40.
  • this mast-carrying element 40 is constituted by a tubular element comprising a hollow housing, open at at least one end 48, and capable of receiving the end 50 of the mast 7 which can thus be positioned simply by plugging into the housing produced in the mast holder 40.
  • the mast holder can be opened at its two ends and, when it is in a determined position, to position the mast correctly as shown in FIG. 3A, l end 44 may correspond to an opening 49 in beam 20, so that the mast has at least one part which completely passes through the hollow housing of the mast-carrying element 40 and that a small part of short length of its end 50 can cooperate with the orifice 49 produced in the beam 20.
  • the end 50 can pass right through the beam 20, so as to be able to cooperate, as will be explained below , especially next to the Figur e 4, with a tensioning cable of the articulation arms as illustrated and which will be described in more detail, in particular with regard to FIGS. 5A and 5B.
  • the orifice 49 produced in the beam, whether or not it passes through, will be lined in a sealed manner so as not to compromise the flotation of the beam when it is hollow, as mentioned above.
  • the hollow housing thus produced in the mast holder 40 will be a cylindrical housing of revolution allowing the mast 7 - its end 50 having a cross section complementary to that of the housing - to be able to turn on itself around its longitudinal axis 53, when it is positioned in its mast holder 40.
  • This advantage will appear in more detail in particular in the description of Figure 6A.
  • the structure also comprises two lateral arms 4 and 5. These are more particularly represented in FIG. 4 where these two lateral arms 4 and 5 are formed in one and the same rod 60 affecting the shape of an arc of a circle and positioned in cooperation with the body 1, so that the middle 61 of this rod is substantially located near the mast holder 40 and its axis of rotation 41 as defined above, for example slightly forward so as not to prevent the rotation of the mast holder as described above.
  • This rod 60 can thus be fixed in its middle 61 to the spacer means 42 and 43 by any means, and in particular, for example, by a clamp 69.
  • This rod is defined in a plane and is positioned relative to to the beam 20 so that a first plane containing the rod 60 and a second plane containing the axis of the beam 20 are substantially perpendicular but that, in addition, its two ends are slightly in front of the end 28 constituting the front of the boat, so that an imaginary line 64 passing through the two ends 62 and 63 of the rod 60 is substantially tangent to the first curved part 21 of the beam, substantially in its middle 65, as this appears in particular with regard to Figures 1 and 2. It will of course be possible to use a rod having a smaller radius of curvature so that the imaginary line 64 passes below the curved part 21 of the beam 20. This will depend essentially ent constructive modalities.
  • the general shape of an arc and the position of the rod 60 are particularly advantageous for connecting the floats as has been said previously, because the shocks which these floats undergo are thus transmitted to the arms, while allowing the beam to be subjected 20 rotations or twists substantially around a horizontal axis perpendicular to the second plane containing the beam 20 and thus to be able to constitute a relatively rigid structure but despite everything flexible enough to absorb the energy of shocks due in particular to waves, before this energy is not transmitted to the body 1 proper.
  • this rod 60 its two ends 62 and 63 are connected by a second tensioning cable 66 which is essentially contained in the second plane as defined above and connected at a plurality of points to the rod 60 in its middle part by sub-tensioners such as 67, 68, etc ...
  • this tensioning cable is positioned in such a way that it can pass under the beam 20 with respect to this rod 60 and at the level of the orifice 49 crossing the beam 20 in such a way that, as explained above and illustrated more particularly in Figure 4, when the mast 7 is positioned in its mast holder 40, its end 50 of small diameter may possibly abut against this second tensioner 66, possibly even deform it as shown in dotted lines, to accentuate the tension at the two ends 62 and 63, and moreover allow despite this rod 60 to be able to deform by tending to straighten, for example under the action of shocks applied to the floats.
  • the two characteristics defined above respectively the shape of the rod 60 and the position of the mast 7 on the tensioner 66, contribute doubly to absorb the forces on the floats when the boat encounters, for example, waves of a certain amplitude. .
  • the two lateral arms 4 and 5 respectively support the floats 2 and 3.
  • a float for example the float 3 connected to the arm 5.
  • This float is constituted, for example, by a hollow enclosure to allow flotation, but also of substantially profiled exterior shape for better penetration in water.
  • Such a float has no particular characteristics and is well known in itself.
  • its middle part 70 is constituted by a cylindrical part of revolution surrounded by a sleeve 71 which supports, fixed laterally, the drift means 14, such as for example hydrofoils or drifts , or drift tails, or other well-known elements making it possible to give stability in the advance of the boat and possibly to obtain, in addition, an improvement in the propulsion of the boat, for example by means of hydrofoils, for lifting the entire structure as much as possible above the waves and thus limit the frictional forces on the water.
  • the drift means 14 such as for example hydrofoils or drifts , or drift tails, or other well-known elements making it possible to give stability in the advance of the boat and possibly to obtain, in addition, an improvement in the propulsion of the boat, for example by means of hydrofoils, for lifting the entire structure as much as possible above the waves and thus limit the frictional forces on the water.
  • FIG. 5B represents a block diagram showing the position of two floats with respect to the body 1, sketched on this figure so as not to weigh it down.
  • this type of boat is mainly intended for leisure more than high competition. Consequently, these boats must be able to be brought to all places and in particular to the beaches. In this case, for the ease of transport of such a structure, especially on the sand, it is advantageous to be able to erase or retract the drift elements or hydrofoils such as those illustrated and described in Figure 5A, to prevent the boat does not rest on the sand directly on them and rather rests on the floats.
  • the pivoting sleeve 71 is associated with at least two traction cables 73 and 74 fixed at least at one point to the sleeve 71, for example at point 75, and the two ends are associated with said sleeve so that the two cables can exert tensile forces in two diametrical planes not confused.
  • the two cables can exert tensile forces in two diametrical planes not confused.
  • these two cables 73 and 74 may be connected to two winch means to obtain, as illustrated diagrammatically in FIG. 5B, the same simultaneous traction on the two sleeves 71 associated with each of the floats and thus obtain synchronization of the brought drift elements 13,14, either in the lowered position, or in the raised position.
  • These winch means schematically represented at 72 in FIG. 5B are known and do not pose any difficulty to those skilled in the art. They will therefore not be described more fully here.
  • the edge 80 of the sail 8 is fixed longitudinally along the mast 7.
  • the sail instead of being lowered as in conventional sailboats, is wrapped directly around the mast. To be able to unroll it, it suffices for example to exert traction on its end 81 and, in this case, the mast begins to pivot in order to unroll the sail 8.
  • handle means 82 are associated with the mast 7.
  • handle means 82 can advantageously consist of an element well known under the name of wishbone 83.
  • a wishbone is essentially formed by two substantially parallel tubes 84 and 85 connected respectively at their ends 86 and 87, the end 87 being able to be pivotally mounted, around a secondary sleeve 88 for example, on the mast holder 40.
  • the end 81 of the sail 8 is associated with a traction cable consisting of a cable 89, one end 90 of which is linked to the end 81, passing for example through an eyelet 100, and the other end of which is linked to the mast, for example in its lower part 91.
  • This traction cable comprises different elements which are, for example, a first pulley element 92 rotatably attached to the end 86 of the wishbone furthest from the mast, the cable 89 passing on the has a pulley 92 and is then wound on the lower part 91 of the mast in a direction which is opposite to that in which the sail 8 was wound.
  • these cables are associated with tensioner means 93, such as those illustrated in particular in Figure 6A and in more detail in Figure 6B.
  • tensioner means 93 may consist, in association with a wishbone 83, of a sliding rod 94 with which are associated two pads 95 and 96 forming guide rollers and capable of cooperating respectively with the two tubes 84 and 85 forming the wishbone.
  • rollers 95 and 96 in addition to their rotation, can move laterally on the rod 94, as indicated by the arrows 101 and 102, so as to be able to be constantly in cooperation with the two lateral arms of the wishbone which are generally of substantially shaped in an arc. Between these two rollers 95 and 96 is disposed a guide roller 97 under which passes a portion 103 of the cable 89. This roller 97 can even be associated with a loop 105 of the cable 89 which cooperates by sliding in eyelets 106, 107, made on the lower edge 104 of the sail 8. In this way, by moving this rod more or less 94, it is possible to enlarge the loop 105 more or less and therefore to obtain variations in the tension of the cable 89 up to to a desired value which gives the sail the desired tension.
  • this boat can be used in complete safety, and for all of its possibilities, it is advantageous to provide, from the outset or during manufacture, on its basic means which constitute the oblong body and the lateral arms, means attachment of different elements, to allow navigation, whether of the fittings, the rigging. or the pipe, etc. It is more advantageous to provide these attachment means adapted to the elements which must come to cooperate with these means.
  • first hooking means 200 for a seat 201 on which a potential user of such a boat can sit.
  • These fixing means 200 can be constituted, in an advantageous embodiment, by a threaded part 202 secured by welding, for example, to the upper end 203 of the part 22, this threaded part 202 passing through an orifice 204, for example square, from the edge 205 of the seat 201. This edge 205 is then sandwiched between the upper end 203 of the part 22 of the oblong body 1 and, for example, a nut 206.
  • the seat 201 is adapted to form a slightly hollow shell so that the user of the boat can sit properly and, moreover, also wedge slightly.
  • This rear part 25 of the part 22 of the oblong body 1 can therefore comprise, on each side, at equal distance, at an average length for the legs of people able to use such a type of boat, hooking means 210 and 211 two note pads 212 and 213 respectively.
  • hooking means 215 consisting for example of an output tab 250 of a ball joint 216.
  • This tab 250 is secured, for example by welding, of the end 25 of part 22, at a point located near the seat 201, on the face 252 of the oblong body 1 opposite that 253 on which this seat is hung.
  • the other tab 251 of the ball joint 216 is integral with the edge 218 of a plate 217 advantageously profiled hydrodynamically.
  • the plate 217 can take any position in a solid cone 229 the apex of which is centered on the point of rotation of the ball joint 216.
  • this profiled plate 217 can be used for several functions: as a supporting plane to stabilize the boat and as a rudder, by tilting it in the desired directions, on one side of the navigation line given by the longitudinal axis of the body 1 and in a non-horizontal plane. These two movements are represented, for stabilization, by displacements along arrow 227, and for rotations in oblique planes on either side of oblong body 1, by arrow 228.
  • This plate 217 therefore advantageously replaces the rudder as briefly described and referenced 26 and 27 above with reference to Figure 3A.
  • an advantageous means for controlling the position and the orientation of this plate 217 is constituted by a circular ring 220 which is secured substantially at at least one point 221 of this plate 217, substantially in its middle.
  • This ring has a sufficient radius so that it can surround the seat and the person when the latter is seated on this seat, for all the possible positions that this plate 217 can take, both as a stabilizer and as a rudder, when it is moved into its previously mentioned solid cone.
  • the structure comprises a link 222 fixed at one of its ends 223 at a point 224 substantially diametrically opposite to point 221 on which the plate 217 is attached. 'other end 225 of this link 222 passing through a pulley 226 fixed to the front of the seat 201, substantially at the level of the fixing means 200 so that the user can then, as easily as possible, pull up on this link 222 which is at its scope.
  • attachment means have been given in the case of cooperation with a seat, a rudder and toe clips.
  • the arms 4 and 5 could be constituted by beams of generally cylindrical shape of revolution.
  • the shape of the section of these arms is illustrated in Figure 8 which is a simplified section along the plane referenced A-A in Figure 9, which shows the general shape of the boat structure according to the invention.
  • the circular shape of the arm 5 makes it possible to achieve, with its external surface, a pulley-shaped hooking function in particular for the sub-tensioners 67, 68 like those which are connected to the tensioning cables 12 and 66.
  • the tensioning cable 12 going around the ends of the structure of the boat and the tensioning cable 66 connecting the two ends remote from the two arms 4 and 5, are connected by sub-tensioning cables 230 of which one of the ends 231 is fixed to the portion of cable 12 passing substantially on one side of the arm 5 (or 4), and the other end 232 of which is fixed to the other portion of the tensioning cable 12 located on the other side of the arm 5, this sub- tensioner 230 having trapped in a free complete loop 233, both the beam of the arm 5 and the tensioner cable 66 connecting the two ends of the two arms.
  • This attachment means being easy to perform, it also allows the tension cable 66 to be left free by sliding with respect to the sub-tension cable which links it to the two arms.
  • the tensioning cable 66 can therefore slide over the interior of the loops 233 of the tensioning cables arranged all along these arms to thereby distribute the forces all along the arms and on all the tensioning cables instead of having these forces absorbed only by the first tensioning cables closer to the float having suffered this shock.
  • All of these fabrics 240 are stretched and hung between the different portions of the tensioning cable 12 and pass, for example, above the tensioning cable 11 to be hung, at one end, near the seat 201, and, at the other end, on the arms 4 and 5.
  • the front of this structure may also include a canvas 240 stretched between these same two arms 4 and 5 and the portions of the tensioning cable 12 which are connected to the front of the body oblong 1.
  • These fixing means can be, in an advantageous embodiment, the ends 241 of sub-tension cables 242 arranged and distributed all along the central beam and arms 4 and 5, in association with the tension cables 10, 11, 12
  • These ends 241 include hooks 243 passing through eyelets 244 produced on the edge of the fabrics 240. This makes it possible to hang and tension the fabrics, for example between the two portions of the tensioning cable 12 located on either side of the center line of this boat structure.
