Definitions
- the present invention relates to boats of the pleasure craft type, and more particularly to the sail 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 sports performance while having a very simple design allowing easy transport, disassembly and reassembly very easy.
- This structure due to its qualities, makes it possible to arrive at a cost price very much lower than that of boats having or which may have comparable performances.
- the present invention relates to a boat structure comprising an oblong central body, two floats, two lateral longi ⁇ arms of which one of their ends is secured to said body by first fixing means and second and third means of connection of the other two 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 CB 922.065 (Welman).
- the boat structure according to the invention is characterized by the fact that said body consists of a beam comprising two parts abutted to each other along a junction surface, a first relatively short part of shape substantially in an arc having a first value of curvature R1, a second longer part than the first part, of substantially arcuate shape 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 through 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 mast carrier in a determined position with respect to said beam.
- said structure is also characterized in 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 substantially complementary section from 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 attaching navigation elements and to at least one navigation element cooperating with said attachment means.
- Figures 1 and 2 respectively show, partially in side view, in perspective and from above, an embodiment of a boat structure according to the invention, of the trimaran type with a central part bordered on either side by two floats connected to the central part by two arms.
- - es gures e repr sen en p us en aa par e cen ra eu embodiment according to Figures 1 and 2
- FIG. 4 shows a view of the two arms of the embodiment according to Figures 1 and 2
- FIG. 5A and 5B show in more detail the floats as shown in the embodiment according to Figures 1 and 2
- FIG. 6A and 6B show in more detail the elements of the mast and the sail capable of being mounted on the boat structure as shown in Figures 1 and 2, - Figures 7A and 7B show a detail of embodiment essentially concerning the means to govern the boat,
- FIG. 8 represents a detail of an embodiment of another characteristic according to the present invention, to allow better distribution of the forces during navigation on a surface comprising, for example, waves,
- FIG. 9 shows a final detail of an additional characteristic allowing, in a very slight way, to advantageously increase the useful deck area for such a boat, in accordance with the present invention.
- all of the figures represent a single and same embodiment of a boat structure according to the invention. Consequently, the same references designate the same elements and, for the understanding of the description, it will be interesting to refer to one or other of the figures where said referenced element appears best.
- Figures 1 and 2 represent, in two different views, the 'one in perspective slightly from the side and the other from above, an embodiment of a trimaran type boat structure, comprising a central body 1 bordered on either side by two floats 2 and 3.
- floats are connected to the central body 1, respectively by two arms 4 and 5 which are secured at a point on the two floats 2 and 3 and by connecting means on the central body 1.
- a door mast 6 in which is able to position a mast 7 for supporting at least one sail 8 which can be stretched, for example by handle means 9, such as the element known under the term of wishbone.
- tensioning means 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 essentially consists of a longitudinal beam 20 comprising at least two parts 21 and 22.
- This two parts 21 and 22 are butted together according to a first junction surface substantially defined at 23.
- These two parts 21 and 22 affect the shape appreciably of an arc of a circle, 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 an arc of a circle, has a radius of curvature R2 whose value is clearly greater than the value of R1 defined above.
- 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 on 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. This can be optionally maneuvered by any arm element as dried atically illustrated in 27.
- the two ends of the beam 28 and 29 are connected by a traction cable 30 making it possible to exert a certain force at each end.
- This cable 30 may 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 mounted pivoting about an axis 41 advantageously perpendicular to the plane in which is contained the curved axis 0 of the beam 20.
- the bearings of support 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 relatively fixed position relative to the beam 20.
- the rotation of this mast holder 40 as described above 5 obviously has the advantage of making it possible to place the mast 7 in cooperation with the other elements of the structure, very easy way.
- this mast carrier element must include means for blocking its end 44 relative to the beam 20, so that, when the mast is positioned in the mast carrier element 40, as illustrated in Figure 3A, it is in the normal position that a mast must have in relation to such a type of boat.
- These locking means 44 are simply illustrated, in particular 5 in Figure 3B, a pawl 46 engageable with a corresponding notch 47 formed in the end 44 of the element holder mast 40.
- this mast-carrying element 40 is constituted by a tubular element comprising a hollow housing, open at at least one 0 end 48, and capable of receiving the end 50 of the mast 7 which can thus be positioned simply by plugging in in 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, the end 44 can correspond to an opening 49 in the 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 0 the beam 20, so as to be able to cooperate, as i l will be explained below, in particular with regard to FIG. 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 buoyancy 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 with respect 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 forward relative to the end 28 constituting the bow 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 appears in particular with regard to FIGS. 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 pout re 20. This will essentially depend on the 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 in spite of everything flexible enough to absorb the energy of impacts due in particular to waves, before this energy is 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 can possibly abut against this second tensioner 66, possibly even deforming it as shown in dotted lines, to accentuate the tension at the two ends 62 and 63, and moreover allow this rod 60 to be able to deform by having a tendency 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 external shape for better penetration into the 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 whole structure at maximum 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 whole structure at maximum 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, in particular 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 non-confused diametrical planes.
- e * n exerting a tensile force on one of the two cables 73 or 74, it is possible to pivot this sleeve around the middle part 70 of the float 3 and obtain either the lowered position as shown in solid lines on FIG.
- these two cables 73 and 74 could 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 supply of the 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 classic 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 unwind 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 to 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 constituted by 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 fixed rotati ⁇ ve to the end 86 of the boom furthest from the mast, the cable 89 passing over the pulley 92 and then being 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 can consist, in association with a wishbone 83, of a sliding coulis 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 arcuate shape. 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.
- this boat can be used safely, and for all 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 for attaching different elements, to allow navigation, whether it be elements of the fittings, of the rigging, or of the pipe, etc. . I t is more advantageous to provide these attachment means adapted to the elements which must come to cooperate with these means.
- first hooking means 200 of a seat 201 on which can sit a potential user of such a boat are provided at the rear end 25 of the portion 22 of the oblong body 1.
- These fixing means 200 may 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 edge 205 of 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 correctly 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 toe clips 212 and 213 respectively.
- This tab 250 is secured, for example by welding, to the end 25 of the part 22, at a point located near the seat 201, on the face 252 dif oblong body 1 opposite to 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.
- the user when seated on the seat 201, can control or give this plate the desired position and orientation when his boat is moving on the water.
- An advantageous means for controlling the position and orientation of this plate 217 is constituted by a circular ring 220 which is substantially secured at at least one point 221 of this plate 217, substantially in the 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 includes 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 within reach.
- 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 carry out 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 relative to the sub-tension cable which links it to the two arms.
- the tensioning cable 66 can therefore slide on the inside 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 cables tensioners closest to the float having suffered this shock.
- means may be provided for hooking both on the bodies, such as the central beam or the arms, and on the tensioning cables 10, 1 1, 12, in order, for example, to stretching fabrics 240, to increase the surface of the "bridge" of this structure.
- This increase in surface area thanks to the fabrics 240, has at least two advantages: on the one hand, allowing the user to move for different reasons on this structure, for example to hang the sails, stretch the ends, etc. , on the other hand, protect it against sprayed water, etc. .
- 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 fabric 240 stretched between these same two arms 4 and 5 and the portions of the tensioning cable 12 which are connected at the front of the oblong body 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.
