Definitions

  • the present invention relates to a device for guiding a furling tube of a mainsail.
  • the sail having to be able to occupy various positions relative to the mast or the boom because of the hollow which it presents when the furling tube is arranged parallel to the boom or the angle of incidence which it presents and its cant when the winding tube is arranged parallel to the mast, provision is generally made for the crescent (s) to be articulated with respect to said boom or to said mast.
  • the invention solves the difficulties encountered.
  • the device for guiding a mainsail furling tube arranged parallel to the mast of a ship and connected to a motor mechanism to cause the winding respectively the unwinding of a mainsail otherwise connected to a boom, said tube being held near the mast by at least one crescent is characterized by at least one cable or rod fixed to a fitting at the head of the mast and to the boom so that this cable or rod extends parallel to the winding tube, said cable or rod being kept under tension and connected in the vicinity of one end of the crescent, itself connected to the mast by an articulation.
  • Fig. 1 is a partial schematic elevation of a mainsail furling mast applying the invention.
  • FIG. 2 is a perspective, on a larger scale, illustrating the detail appearing in FIG. 1.
  • Fig. 3 is a partially schematic and greatly enlarged plan seen along line III-III of FIG. 1.
  • Fig. 4 is a sectional elevation seen substantially along line IV-IV of FIG. 3.
  • Fig. 5 is a sectional elevation, on a larger scale, of a detail of embodiment of a crescent illustrated in FIG. 4.
  • Fig. 6 is a schematic partial elevation seen along line VI-VI of FIG. 1.
  • Fig. 6a is an elevation similar to FIG. 6 of an improved variant.
  • Fig. 7 is a schematic plan seen substantially along line VII-VII of FIG. 6a.
  • Fig. 8 is a section taken along line VIII-VIII of FIG. 7.
  • Fig. 1 shows a mast 1 of a ship 2.
  • the mast 1 is provided with a furling tube 3 for a mainsail 4 connected by a listening system 5 to a boom 6.
  • the mast 1 has spreaders 7, 8 to keep a shroud 9 apart.
  • listening system 5 is connected to a winch 10 to border respectively shock the mainsail 4 and the roller tube 3 is in turn connected to an electric or hydraulic motor mechanism 11, even manual, to drive it in rotation when the mainsail should be rolled or, on the contrary, unrolled.
  • the boom 6 is connected to a mullet glass 12 so that it can pivot relative to the mast when the mainsail 4 is bordered or on the contrary shocked.
  • the mast 1 is provided with crescents 13, 13a, ... the number of which depends on the height of the winding tube 3 and, consequently, on the height of the mast 1.
  • Each crescent 13, 13a, ... is connected to the mast 1 by a pin 14 carried by lugs 15 (fig. 3 and 4), itself fixed to the mast by any appropriate means, for example collars 16 (fig. 1).
  • each crescent is advantageously constituted by means of two fittings 17, 18 which are symmetrical and which are connected together at their open end by sockets 19 with flared ends 20 (fig. 5).
  • Rollers 21, for example made of polyamide or similar material, are threaded on the sockets 19 to come into contact with the sail 4 while preventing this sail from ragging against living parts.
  • the fittings 17, 18 form pads 22, 23 and are kept apart by a spacer tube 24 threaded on the axis 14 relative to which the pads 22, 23 can pivot.
  • Fig. 3 shows that the opening 25 delimited by each crescent and through which the sail 4 passes is width smaller than the diameter of the winding tube 3 so that it can in no case come out of a crescent even when the sail 4 is fully unwound.
  • the location of the axis 14, around which the crescent is articulated is advantageously chosen so that the two branches 131, 132 (fig. 3) are of different length so that the part of the sail 4 unrolled which door against the rollers 21 of one end of a branch is substantially in the vertical plane of the axis 14.
  • the axis 14 is offset with respect to the geometric axis 3a of the winding tube 3 so that the latter bears against the inside of the branch 131, the longest of the crescents by the external face of the veil 4 when the internal face of this veil bears against the rollers 21 of this same branch.
  • the internal face of the fittings 17, 18 of the crescents is coated with pads, linings or anti-friction rollers 171, 181 for example made of polyamide.
  • Fig. 3 shows a position that can be occupied by the furling tube 3 and the mainsail 4 but this position is not constant, the furling tube 3 being able to bear against the rollers 21 of the two branches 131, 132 or against the pads or linings 171, 181 depending on the sailing conditions and the tack of the sail.
  • the sockets 19 of the crescents are used for the passage of cables or rods 26, 27 fixed at one end to a fitting 28 disposed at the head of the mast and at the other end to ears 29, 30 of the boom 6.
  • the cables or rods can slide freely in the sockets 19.
  • connection of the cables or rods 26, 27 to the boom 6 is ensured by a turnbuckle 31 and possibly a tension limiter 32 of the spring jack or gas jack type.
  • the drawing illustrates with its fig. 2 that the limiter 32 includes a spring 33 compressed by a piston 34 connected by a rod 35 to the turnbuckle 31.
  • the tension limiter 32 is intended to compensate for the differences in length that the cable or rod 26 may have when the boom is pivoted 6 from edge to edge.
  • the cables or rods 26, 27 which are arranged in alignment with the open ends of the crescent (s) constitute guides for the crescents by maintaining these in a similar angular position while taking into account the twisting of the sail 4 along its luff.
  • fig. 5 shows that sheaths 36, 37 are threaded on each rod or cable.
  • the sheath 36 which is located above the sleeve 19 of each crescent is provided with at least one support roller 38.
  • the sheaths 36, 37 are preferably made of anti-friction synthetic material, for example polyamide and can be fitted from place to place, as shown in the lower part of fig. 5, pebbles 39.
  • rollers 39 are arranged to bear on the external face of the sail 4 unwound from the tube reel 3 which is illustrated in FIG. 7.
  • roller guides 40 are arranged opposite the rollers 39 on the other face of the sail.
  • the guide assemblies constituted by the rollers 39 and multiple roller guides 40 are carried by the cables or rods 26, 27 or the sets of cables or rods 26, 27, 26a, 27a, etc.
  • Figs. 7 and 8 illustrate a schematic embodiment of a guide assembly mounted on the cables or rods 26, 26a, 27, 27a.
  • a sleeve 41 respectively 42 is provided to be tightened, on the one hand, on the cables or rods 26, 26a and, on the other hand, on the cables or rods 27, 27a.
  • the sleeve 41 supports the roller 39 while the sleeve 42 supports disks 43, 44 for axes 45 on which are rollers 46, 46a, 46b, ...
  • the sail 4 unwound from the winding tube 3 can be brought into contact with the roller 39 of one of the guide assemblies, this roller guiding its outer face and tending to move the cable or cables or rods 27, 27a to the right of the drawing to rotate the croissants 13, 13a in the same direction.
  • the sail can also bear against the multiple roller guide and, in this case, it necessarily relates to at least one of the rollers, for example on the roller 46b.
  • the guide assemblies just described which comprise the roller 39 and the multiple roller guide 40 are guide assemblies by rolling the sail and its winding tube, these guide assemblies ensuring maintenance of the veil whatever its slope and simultaneously ensuring the maintenance of the winding tube to limit its deformation in the intervals between the crescents.
  • guide assemblies can also be arranged between the fitting 38 and the crescent 13 and / or between the crescent 13a and the boom 6.
