Definitions

  • the present invention relates to improvements made to devices, called reels, intended to modify, by winding, the surface of a sail and constituted, essentially, by a tube or profile, rotating around its axis under the action of a system. control, tube or profile of which the sail is made integral and around which it winds.
  • the invention is intended to apply more particularly, but not exclusively, to mainsail furlers.
  • This reel whose tube or profile 1 is arranged in the center of a centering tube 2 which is coaxial with it, is, as shown in Figures 1 to 3 of the accompanying drawings, either placed outside the mast 3 or at the inside the mast, as shown in Figure 4.
  • the tube or profile 1 must be placed at the shortest distance A from the mast.
  • the elements which determine this distance between the rear face of the mast and the winding tube axis are on the one hand the diameter B of the tube with the sail completely rolled up (Fig. 2), on the other hand the diameter C of the winding control 4 which rotates the reel tube (see Figure 5).
  • the diameter C of the control 4 should be, as far as it is concerned, as large as possible so as to reduce, as far as possible, the effort to be exerted on the rope control to practice the winding of the sail in optimal conditions.
  • one of these systems provides for control by a storage drum 4, in this case it is necessary to separate the winding profile from the mast by a significant distance A ', at least equal to the sum of the diameter D of the drum and of a quantity equal to the radius of dimension C.
  • another system uses a worm. If, in this case, the diameter of the body of the screw is less than the distance from the axis of the winding tube, to the rear face of the mast, this device has the disadvantage of storing the control line and being therefore very long and difficult to position on the mast.
  • the invention makes it possible to avoid these various drawbacks and to minimize the distance between the rear of the mast and the reel.
  • the torque exerted on the winding control can be very large because the radius E of the toothed pulley is significantly greater than the radius of the winding tube 1.
  • the winding system constituted by the toothed pulley can also, as shown in Figure 8, be provided above the gooseneck (not shown) in a cutout made in the mast.
  • the torque which will have to be exerted for the rotation of the tube will be greater than in the case where the system is housed in the mast foot or under the latter but it will still be less important than that it is necessary to develop with known systems.
  • Another improvement of the invention consists of a system for stretching the sail on its furler.
  • the sail is fixed in its lower part, on the base of the tube or on the drum controlling the winding, the upper part of the sail being able to be tensioned by means of a halyard.
  • the disadvantage lies in the fact that, when the winding tube turns, the halyard is also rotated, which causes it to be wound up, by about 10 to 20 turns over a very low height of 10 to 30 cm. In most cases, the halyard breaks or the hose reel becomes blocked.
  • the system according to the invention eliminates these drawbacks.
  • the sail 8 is stretched in the upper part by a halyard 9 passing through a pulley 10 secured to the winding tube 1 and therefore rotating with it.
  • the halyard descends in the axis of the winding tube and, in the lower part of the winding control, it comes out by a pulley 11, integral with a fixed part, for example, in the case treated, of the shaft 12 , fixed in rotation, the winding drum 13 or any other part of the mast or of the boat. This pulley cannot therefore rotate.
  • the hauling system according to the invention by internal halyard, makes it possible to quickly haul a sail as with a cursor, quickly and efficiently and also to quickly sail the sail without the need to lengthen the halyard.
  • the system according to the invention therefore makes it possible to combine the advantages of known systems by eliminating their disadvantages. It is very reliable because it does not have rotating parts and is very economical due to the very limited number of these parts.
  • the system according to the invention can be applied both to mainsail furlers mounted outside the mast and to mainsail furlers integrated in the mast also to jib furlers.
