Definitions

  • the present invention relates to the means used to ensure the establishment, the adjustment and the storage of a sail of a boat and it relates, more particularly, to mainsail devices or the like, involving a structure of establishment comprising a mast, generally vertical, and a boom, generally horizontal.
  • the first problem lies in the need to be able to store the unused sail, for example, when the boat is docked.
  • the second problem is the need to be able to adjust the sail area offered to the wind, depending on the desired gait pace or atmospheric conditions.
  • the storage of such a sail is carried out by forming successive folds, that is to say by closing the sail which is then secured to the boom by means of flaps.
  • the protection of the folded sail is ensured by a laced awning. This set gives an unsightly appearance to the boom.
  • These means generally include a boom mounted articulated on a mast by means of a universal joint or with a universal joint. The association of the boom and the mast is completed by a mechanism for rotating the said boom on its axis.
  • the boom is produced in the form of a cylindrical mandrel and has, in its outer peripheral surface, an open tunnel intended to receive the border line rope which can be stretched in this tunnel, by the through a tensioning or stretching device, generally accessible from the free end of the boom.
  • Such means are generally satisfactory because, after having shocked the edge rope and released the mast halyard allowing the luff rope to be pulled out, it is possible to control the rotation of the boom.
  • the sail can thus be wound or unwound in successive turns and therefore offer an active surface that can be easily and quickly established according to the desired gait pace or atmospheric conditions.
  • the means known above give complete satisfaction.
  • a solution could consist in building the b8me by taking as a starting point the technique of realization of a mast.
  • a mast internally comprises a magazine containing a mandrel of small section allowing the winding, from the luff, of a sail passing through an axial slot formed in the mast.
  • the construction technique would then have consisted in producing, in a similar manner, a boom by providing for the provision of the sail passage slot at the level of the top surface portion.
  • the obligation to provide a slot in the top part of the boom implies a reinforced construction, for example in parallel double boxes, so as to give the boom sufficient mechanical resistance to bending, buckling and the twist.
  • a reinforced construction results in giving the boom a particularly high weight, while this factor is generally the subject of all research for reduction.
  • a boom with a cross-section of 100 mm and a length of 4.20 m weighs, in general, in traditional constructions, around 14 kg.
  • a boom with the same winding characteristics would have a diameter of 230 to 350 mm and would weigh 40 kg, that is to say almost three times more than a known conventional boom.
  • the transposition to a winding boom of the known mast construction technique could therefore not be envisaged or retained.
  • the object of the invention is to provide a new sail furling and storing device, from the edge line and which is able, while offering the known characteristics of establishment, storage and adjustment, to meet positively to storage and protection issues bad weather and solar ultraviolet radiation.
  • the object of the invention is to provide means having the particularity of being able to be easily adapted on existing winding booms and thus allowing adaptation on demand, whatever the type of boom to be equipped.
  • Another object of the invention is to provide means which are relatively simple and inexpensive, while ensuring effective protection of the sail.
  • Another object of the invention is to provide means of a low overall mass which, moreover, penalizes only very slightly the drag coefficient of the whole rigging.
  • Yet another advantage of the subject of the invention lies in the simplicity of the means of implementation which make it possible to carry out assembly or, possibly, rapid disassembly, without it being necessary to have recourse to qualified personnel for this. to do.
  • An additional object of the invention is to provide storage and protection means which do not limit conventional interventions at the boom level in order to adapt the characteristics of the latter to sailing conditions.

  • Fig. 14 is a cross section taken along line XIV-XIV of FIG. 13.
  • Figs. 15 and 16 are two cross sections illustrating two characteristic states of a development.
  • the winder and stacker device relates to a boom 1 associated with a mast 2 rising from the deck of a boat 3, shown diagrammatically in FIG. 1.
  • the boom 1 and the mast 2 are intended for the establishment of a sail 4 which is shown in the drawings by way of example, in the form of a marconi rigging.
  • the object of the invention finds, however, the same application in the case of different rigging and, in particular, in the case of auric rigging.
  • a boom comprises, in known manner, as illustrated in FIGS. 2 and 3, a mandrel 1a of cylindrical or oval section which is mounted on the mast by means of a joint 5, of the universal type, or alternatively in Cardan joint.
  • the articulation 5 is associated with a mechanism 6 for driving the mandrel 1a in rotation on its axis.
  • the free end of the mandrel 1a can be maintained by means of a sheet 7 attached to a traction point 8 carried by the deck 9 of the boat 3.
  • the mandrel 1a can be made of different materials and has, in its peripheral surface, a groove or an axial tunnel 10 extending over the entire length.
  • the tunnel 10 is intended for the passage and maintenance of a rim line 11 fitted to the sail 4.
  • the rim line 11 can be stretched between the armor point 12 and the listening point 13 by means of a stretching device 14.
  • Fig. 1 shows that the sail 4 has been established, in order to offer its entire surface to the wind, by means of a mast halyard making it possible to slide the luff line in a suitable tunnel presented by the mast. From this state, the tension of the mast halyard can be canceled to allow the boom 1 to rotate in order to wind the sail 4 in successive turns. This makes it possible to reduce the surface of the sail according to determined proportions, as illustrated by the two dotted lines in FIG. 1 and therefore to adapt the reactions of said sail as a function of navigation conditions or atmospheric conditions. The complete winding on the boom allows to proceed to storage under suitable conditions permitting rapid subsequent recovery.
  • a boom of the above type is equipped according to FIGS. 2 to 4, of a sheath 15 of deformable material.
  • the sheath 15 may be constituted by a sheet, a film, a sheet, openwork or not, of textile, plastic material or else of a laminated complex.
  • the sheath 15 can also be a thin sheet of suitable metal.
  • the sheath 15 has a shape adapted to that of the boom 4 when the sail is completely rolled, that is to say, either cylindrical or frustoconical in the same ratio as the latter.
  • the sheath 15 is produced so as to delimit an envelope whose general internal section available is at least equal to the general section presented by the boom 1 in a fully wound state of the sail 4.
  • the sheath 15 is arranged to surround the boom 1 over substantially the entire length of the latter, being, moreover, arranged so as to have a faculty of independent relative rotation, with respect to said boom. In reality, the assembly is carried out in such a way that the sheath 15 can accept the independent rotation of the boom 1 and be angularly displaced with respect to the axis of the latter in particular conditions of use, as explained below.
  • the sheath 15 is produced so as to delimit a slot 16 defined by two rigid parallel edges 17 extending over the entire length of the boom 1.
  • the slot 16 is normally arranged so as to be placed in coincidence with the luff tunnel 10 in a boom state corresponding to the complete unfolding of the sail 4. The slot 16 thus makes it possible to ensure the passage of said sail as shown in FIGS. 3 and 4.
  • the sheath 15 is mounted on the boom 1 by means of two end support and axial stop parts 18 and 19.
  • the part 18, illustrated in FIGS. 5 and 6, comprises a ring 20 immobilized axially and angularly on the mandrel 1a of the boom 1.
  • the ring can be made of many different materials and be immobilized on the boom 1, for example by means of rivets or of screw 21.
  • the ring 20 is set back from the free end of the boom 1 and reserves an axial distance at least equal to the thickness of a nozzle 22 which is threaded freely on the mandrel la, to be brought in abutment against the ring 20.
  • the endpiece 22 can rotate on the mandrel 1a and is connected to the corresponding end part of the sleeve 15.
  • the part 19 is constituted, as is apparent from FIGS. 3 and 7, by a plate 23 in which are drilled holes for the engagement of two pins 24 which are formed in the extension of the edges 17 of the sleeve 15 defining the slot 16.
  • the axial immobilization of the pins 24 in the plate 23 can be ensured, in particular, by nuts 25.
  • the plate 23 has a height chosen so that, in the position of the sleeve corresponding to a state of rest, in which it bears on the upper part presented by the boom 1, said plate is placed in axial abutment against the transverse face of the boom directed towards the mast 2.
  • the plate 23 could be replaced by two lips articulated on the pins 24 and connected together at their opposite ends by a shackle attached to the mast by a cable.
  • the sleeve 15 is brought by gravity to occupy the position illustrated by the two transverse sections according to FIGS. 3 and 4.
  • the slot 16 is in coincidence with the border line rope tunnel 10 and the sleeve 15 is immobilized axially on the boom 1 in the two sliding directions possible.
  • the mandrel 1a When it is necessary to proceed, for example the winding of the sail 4 from the positions according to FIGS. 3 and 4, the mandrel 1a is rotated by the mechanism 6 after the tension of the mast halyard has been released and the sheet 7 has been, at least partially, shocked.
  • the rotation of the mandrel causes it to be wound in: successive turns of the sail 4 inside the sheath 15 which is biased in angular displacement, for example, in the direction of the arrow f l , due to the displacement of the point of contact between the sail and said boom.
  • Such a point is established substantially at the level of the tangent joining the external periphery presented by the boom 1 at the low point of engagement of the luff line in the line tunnel offered by the mast.
  • the angular displacement of the sleeve 15 is made possible for this purpose by the parts 18 and 19.
  • Fig. 8 shows a partial winding state corresponding, for example, to ten successive turns of veil 4 wound on the mandrel la.
  • fig. 9 shows, for a cross section of the boom identical to that of FIG. 8, a complete winding state of the sail 4 still connected by the halyard point 26 to the halyard of the mast 27. It is understood that, in such a winding state, the stress exerted by the sail 4 no longer exists and that, as a result, the sheath 15 can optionally reoccupy in a natural manner its initial position in which the slot 16 is substantially aligned with the vertical plane passing through the axis of the boom 1.
  • the device according to the invention therefore makes it possible to wind in a traditional manner and to store practically and quickly all or part of the sail 4 which is thus, in such a state, stored while being sheltered from the weather and solar ultraviolet radiation.
  • the means used allow an adaptation of the sleeve 15, in particular in section, since the pins 24 allow a variation in the cross section at the same time as the free engagement of the plate 23 allows the latter to move radially to the as the variation in one direction or the other of the section of boom 1.
  • the means of the invention are simple to implement and have the advantage of adapting to partial or total winding conditions.
  • the sheath 15, of flexible nature adopts in cross section a conformation adapted to the section presented by the boom 1 in winding state.
  • the cross section of the sleeve 15 is in direct relation to the winding state, which makes it possible to confer on boom 1 characteristics or a particularly favorable aerodynamic profile.
  • the comparison of figs. 3, 8 and 9 shows that, for a partial winding, the excess perimeter length of the sleeve 15 is placed vertically above the boom and therefore gives it a master torque reducing the drag coefficient to the most low possible value, while defining a kind of vertical extension increasing the overall surface offered to the wind.
  • the maximum master torque intervenes only in the complete winding state of the sail 4, that is to say in a state of stopping or particularly delicate navigation conditions in which the temporary increase of the master couple boom 1 has no direct impact on gait.
  • an elastic member is chosen to be capable of normally ensuring the load exerted by the sheath 15.
  • Such an elastic member can be constituted by a tension spring 28 interposed, as illustrated in FIG. 2 between the plate 23 and the mast 2. Although this is not shown, may be provided to replace i this elastic member by a compression spring interposed directly between the part or parts of the sheath 15 supported on the upper part boom 1.
  • Figs. 2 to 5 show that the sheath 15 is preferably associated with a ballast 29 normally occupying a position substantially diametrically opposite to the slot 16.
  • a ballast 29 ensures correct establishment of the sheath 15 in a fully or partially unwound state of the sail 4.
  • the ballast 29 can be associated with the sheath 15 by being placed outside the latter or, possibly also, preferably, inside the volume that the sheath delimits with the external peripheral wall of the boom 1.
  • the ballast 29 is preferably constituted by a rigid beam 30, constituted by a "U" or box profile, of circular or polygonal section.
  • the rigid beam 30 is preferably associated with or forms a sole 31 providing sufficient application and sliding surface for the sheath 15, in order to avoid any punctual stress likely to harm the condition of such a sheath, taking into account its constituent material.
  • the rigid beam 30 preferably extends over the entire length of the sheath of which it is made axially integral.
  • the rigid beam 30 is preferably designed and produced to assume an additional support function of at least one point P of application of a tensile force on the boom in the direction of the arrow f 2 .
  • the rigid beam 30 comprises at least one eyelet or stirrup 32 accessible externally to the sheath 15, so as to allow the adaptation of a traction device 33, such as a tan-down.
  • a traction device 33 such as a tan-down.
  • the beam 30 then represents a point of application of the tensile force according to the arrow f 2 and assumes, at the same time, via the sheath 15 and the edges 17, a transfer function and transmission of such a force to boom 1.
  • the rigid beam 30 is able to assume such a function, whatever the state of winding of the sail, it is advantageously provided to establish a connection between the beam 30 and the end piece 22, by means a tie rod 34 ensuring a joining axial, while allowing a possibility of transverse offset.
  • the beam 30 can continue to occupy the required low position, whatever the angular offset inflicted on the sheath 15 by the sail 4, in particular in the case of partial winding, as is apparent from the example illustrated in FIG. . 8.
