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.
  • 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 subject of the invention is therefore a sail furler, more particularly a mainsail furler, constituted by a tube or similar profile rotating around its axis under the action of a control system, tube or profile from which the sail is made united and around which it is wound, characterized in that the control system is housed in the mast foot or under the mast foot, and in that it comprises, for the purpose of the drawing of the sail, a passing halyard in the upper part of the winding tube on a pulley secured to the tube and rotating with it, and this halyard, after having passed through the tube, leaving the winder by a pulley secured to a fixed part of the winder.
  • 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.

Claims (4)

1. Segelrollreffer, insbesondere Großsegel-Rollreffer, bestehend aus einem Rohr (1) oder einem analogen Profil, das sich unter der Einwirkung eines Steuerungssystems (4) um seine eigene Achse dreht, wobei das Rohr oder Profil, mit dem das Segel fest verbunden ist und um das es sich aufrollt, dadurch gekennzeichnet ist, daß das Steuerungssystem im Fuß des Mastes (5) oder unterhalb des Untermastes untergebrachts ist, und daß es für das Hissen des Segels ein Fall (9) aufweist, das im oberen Bereich des Rollreffer-Rohrs auf einer mit dem Rohr (1) einstückigen Seilscheibe (10) läuft und sich mit ihm dreht, und wobei das Fall (9), nachdem es in dem Rohr verlaufen ist, den Rollreffer über eine mit einem feststehenden Teil des Rollreffers einstückige Seilscheibe (11) verläßt.
2. Segelrollreffer nach Anspruch 1, dadurch gekennzeichnet, daß das Steuerungssystem eine Rastscheibe (6) ist.
3. Segelrollreffer nach Anspruch 2, dadurch gekennzeichnet, daß das durch eine Rastscheibe gebildete Steuerungssystem oberhalb des Lümmellagers in einem im Mast ausgebildeten Ausschnitt angeordnet ist.
4. Rollreffer nach Anspruch 1, dadurch gekennzeichnet, daß die Seilscheibe (11), über die das Fall nach dem Rollreffer läuft, mit dem Mast (12), der bezüglich der Drehung mit der Seilrolle (13) des Steuerungssystems für den Rollreffer verbunden ist, fest verbunden ist.
