Sail winder.

  The present invention relates to so-called sail winder devices generally comprising a housing with, in this housing, a rotatably mounted shaft, which shaft is rotatable by any means to reduce the surface of the sail by wrapping it around said tree and on which

  is attached an edge of the sail It concerns more particular-

  sail winders secured with a spar and more

  especially with the mast to wind the mainsail.

  A sail winder of this type is described in German Patent No. 607 045 granted December 15, 1934 and it is said in this patent that this sail winder can serve as a matte

  or spar or be arranged parallel to the spar.

  In practice it is currently required to equip a sail winder boats already launched and have not been designed to receive the masts forming sail winders models marketed, So we limited ourselves to following the teaching of German Patent No. 607,045 to market sail winders which are fixed on the mast by

  means, in particular by means of fittings.

  This has disadvantages in particular because it creates intense aerodynamic disturbances on the leading edge.

2 2528792

  It did not seem possible to remedy this incon-

  come to terms, serious about competition boats,

  A crankcase winder fits into the rear part of the mast, but this makes it necessary to design a profile for each mast section to be equipped, which was prohibitive because it must be done on demand and per unit because of

  multiple sections of masts encountered in the existing fleet

aunt.

  The present invention aims to remedy these drawbacks.

  by making a sail winder adaptable to a wide range of mast sections and which disturbs to a minimum

  the aerodynamics of the mast The sail winder conforms to the in-

  vention is also adaptable to other spars even if aerodynamic problems at this spar are less critical. According to the invention the sail winder housing is extended along its lateral edges directed towards the spar,

  by thin blades fixed to the housing by a line of

  and capable of being applied against and

  with the side surfaces of the spar.

  Depending on the degree of freedom of the joint, the same housing can be adapted to masts having sections within a certain range. Moreover, the section of the mast is linked to the surface of the sail, and therefore to the volume of the sail. the width of the casing has some correspondence with the mast section so that a sail winder of given volume will fit on all masts designed to receive the

curled sail.

  The hinge line could be made by a band of hinges, or using the inherent flexibility of the metal constituting the blade possibly weakened along said lines However, the sail winder casings being preferably made by a profile hollow spun, the articulation is preferably carried out by an emboilting element integral with the housing capable of embolting, with a certain degree of freedom, with a corresponding embolic element integral with the rear edge of the blade With this mode of realization and in particular when the element of integral embolization of the blade is a rod

  engaged in a profile grooved cylindrical groove

  In the case of the housing, the blades can be interchanged between the housings of different dimensions and made

by rolling.

  The fastening with the lateral surfaces of the spar can

  be carried out by any means presenting a mechanical resistance

  sufficient, but preferably by riveting.

  According to a preferred embodiment, the winding housing

  on their back side, between the two lines of arms.

  lateral blades, a profiled projection

  to fit into the mast headrail rail of the mast. The invention will be described in detail hereinafter in the form of a

  preferential embodiment with reference to the drawing

  in which: Figure 1 is a horizontal sectional view of the sail winder adapted to a mast of a first section and Figure 2 a corresponding view of the winder applied to a mast of larger section, In 1 designates the section of the mast and 2 the main sail rope 3 designates the sail winder housing as a whole, 4 the shaft and the sail, the winder housing has substantially a trapezoidal section with the top, corresponding to the short side, rounded The slot 6 of the sail is made in

  the rounded vertex axis The large base 7 is substantially flat.

  Along the two edges are formed slotted cylindrical grooves 8 whose slot 9 is directed substantially the opposite

  and in alignment with the side faces 10 of the housing.

  In each of the cylindrical grooves 8 is threaded a cylin-

  11 integral with a blade 12 which, because of this assembly, can oscillate between two positions on either side of the

  position for which it is in the alignment of the faces 10.

  The edges of the blades 12 are fixed on the lateral faces

back of the mast by rivets 13.

  In the middle of the face 7 is provided a longitudinal core 14 with a bead 15 which can be threaded into the headrace rail 2 of the mast This interlocking position the sail winder before fixing by rivets and ensures a mechanical transmission to the

  mast bending forces transmitted to the winder by the sail.

  A preferred embodiment has been described above in its application to a mainsail winder on the mast, but this can be subject to numerous modifications making it possible to use it on other spars without leaving the

the scope of the claims.
