Definitions

  • the present invention relates to an improvement to the winder-reduction of canopies and, in particular, but not exclusively, to the mainsail furlers according to which the reduction of the airfoil takes place by winding the sail on a rotary tube which extends parallel to the longitudinal axis of the mast, outside of the latter.
  • the invention therefore more particularly aims to eliminate these drawbacks.
  • At least one tube holding device comprising, in a manner analogous to the above-mentioned crescents, at least two curved wings, joined to one another by one of their ends, thanks to a connecting element capable of coming to be mounted on the mast, these two wings extending respectively on either side of the tube, so as to partially surround it, and having, opposite the element of connection, two respective extreme edges centered parallel to the tube and delimiting an axial zone of passage through which the sail can circulate.
  • this device is more particularly characterized in that the aforesaid wings are axially offset with respect to each other, so that the aforesaid extreme edges are axially spaced from each other d 'a determined distance.
  • the lower lateral edges of the abovementioned wings will extend obliquely with respect to the axis of the tube so as to guide the sail towards the said passage area.
  • the above holding device is produced using a curved sheet marrying a tubular shape centered on said tube, the above connecting element then consisting of a shell in the form of gutter, from which extend the above wings.
  • the tube holding device comprises three wings arranged in staggered rows, namely: two wings extending on the same side of the tube and a third wing located on the other side , whose extreme edge is located at the right of the interval between the first two wings, at a determined axial distance from the extreme edges of these first two wings.
  • the previously described holding devices can be mounted on the mast by means of an articulation device involving at least one pivot pivoted parallel to the mast.
  • this rotary tube 3 is mounted rotating around a carrying cable 4 stretched between a bracket 5 located at the head of the mast and a support piece (not shown) fixed towards the lower part of said mast 1.
  • This tube 3 includes a longitudinal groove in which engages and can slide the rope of the sail 6 (shown in broken lines).
  • a swivel 8 On the tube 3 is slidably mounted a swivel 8, the inner part 9 is attached to the headrest 11 of the sail 6, while the outer part 10 which pivots freely on the inner part 9 is connected to a halyard 12 passing by a sheave provided in the bracket 5.
  • This swivel 8 / halyard 12 assembly is used to send the sail 6.
  • a holding device which comprises a holding piece 13 produced using a curved sheet, so as to marry a open tubular shape, substantially coaxial with the tube.
  • this retaining part 13 comprises, in its part oriented towards the mast, a shell 14 in the form of a gutter, the two longitudinal edges of which are extended by three curved wings, namely: two wings 15, 16 respectively located in the two extreme regions of one of the longitudinal edges of the shell 14, delimiting between them a free space 17 of determined width D, and a wing 18 which extends from the central region of the other longitudinal edge of the shell 14, in line with the space 17 between the wings 15 and 16.
  • the rollers 22 and 24 delimit, in vertical projection with the roller 23, a space e of suitable width to facilitate the passage of the sail 6, but nevertheless sufficiently small to retain the tube 3.
  • These front edges 19, 20, 21 are also axially spaced from each other by a distance d1, d2 sufficient to allow the passage of folded parts of the sail 6 during its unwinding.
  • the lower edge 25 of the shell 14 and the lower lateral edges 26, 27 of the wings 16 and 18 are shaped so as to constitute a helical shape. continuous passing around the tube 3 and connecting the lower ends of the front edges 20, 21 of the wings 18, 16.
  • the upper edge 30 of the shell 14 and the upper lateral edges 31, 32 of the wings 15 and 18 constitute a continuous helical shape connecting the upper ends of the front edges 19, 20 of the wings 15 and 18.
  • the pitch of this helical shape may then be less than that of the shape produced by the lower edges 25, 26, 27.
  • the mounting of the holding piece 13 on the mast 1 is ensured by means of an articulation device involving two articulation elements each comprising a link 33, 34 articulated at its ends, on the one hand, on a part support 35, 36 secured to the mast and, on the other hand, on an articulation piece 37, 38 secured to the shell, the axes of this double articulation then being parallel to the axis of the mast.
  • the holding part must be designed so as to delimit an interior volume of sufficient section to allow the passage of the swivel 8.
