Definitions

  • the field of the invention is that of the design and manufacture of capstans (winches in English), for example intended to be secured to a sailboat to tension an end secured to a sail.
  • Winches are commonly used on sailboats to allow crew members to tension the ends connected to the sails.
  • a winch conventionally comprises a frame housing an input shaft and a gearbox.
  • a doll around which is intended to be wound a tip, is mounted movable in rotation around the frame. It is connected to the input shaft by means of the gearbox.
  • a rotation of the input shaft is accompanied by a rotation of the headstock shaft.
  • the gearbox includes several ratios so that it is possible to wrap the end around the headstock at different speeds.
  • the gearbox is generally configured so that a reversal of the direction of rotation of the input shaft is accompanied by a rotation of the headstock in one direction but at different speeds.
  • this winch includes a clutch and means for evaluating the tension in the end wound around the headstock.
  • the clutch occupies a first position in which the headstock can be rotated in a direction according to two speeds, the speed change being obtained by reversing the direction of rotation of the shaft input by means of the crank.
  • the clutch is caused to move to a second position in which the headstock can be rotated in one direction according to two other speeds, the speed change being obtained by a reversing the direction of rotation of the input shaft by means of the crank.
  • Such a winch is particularly effective insofar as it allows crew members maneuver the winch with the most suitable speed ratio taking into account the tension in the end wrapped around the headstock. Such a winch can however be further improved.
  • the variation in the level of tension in the end which results either from the variation of the wind force, or from the level of winding of the end around the headstock, or from a combination of these two phenomena, is necessarily progressive. Indeed, the variation of the wind force is progressive as well as the level of winding of the end around the headstock.
  • the invention particularly aims to provide an effective solution to at least some of these different problems.
  • an objective of the invention is to provide such a capstan which systematically allows to train rotating the doll regardless of the level of tension in the end wrapped around the doll.
  • the invention aims, according to at least one embodiment, to provide such a winch in which at least one speed ratio is engaged in all circumstances.
  • An objective of the invention is also, in at least one embodiment, to provide such a winch which benefits from excellent ergonomics of use.
  • Another object of the invention is, according to at least one embodiment, to provide such a winch which is simple in design and / or reliable and / or simple to use.
  • such a capstan comprises means for holding said clutch means in one or the other of their position whatever the value of said tension evaluated by said evaluation means.
  • the clutch passes from one position to another depending on whether the tension in the end decreases or increases.
  • the variation of tension of the end being generally progressive and not frank, the clutch passes from one to the other of its positions in a progressive manner so that it can temporarily occupy a disengaged intermediate position in which a rotation of the input shaft is not accompanied by any rotation of the headstock. The winch is then temporarily non-operable.
  • the invention proposes an original solution making it possible to ensure that the passage of the clutch from one position to the other cannot take place as long as a certain level of tension in the end is reached.
  • the clutch is always engaged in one or the other of its positions so that the winch is systematically maneuverable.
  • the first and second holding means may be combined at least in part.
  • the first and second means of arming may be confused at least in part.
  • the first and second means of recall can be confused at least in part.
  • said actuating means can be operated manually.
  • a crew member can manually control actuating means to release or not release the clutch.
  • said imprint is linked in rotation to said input shaft, the passage of said imprint from its first or second locking position to its release position being obtained by reversing the direction of rotation of said input shaft.
  • a crew member can thus activate the arming means by reversing the direction of rotation of the input shaft, this whether the winch is manual or motorized.
  • said gearbox comprises an inner ring mounted mobile in rotation under stress inside said headstock between two extreme positions corresponding to the reaching by said tension respectively of said high threshold value and of said low threshold value, and in that it comprises transformation means making it possible to transform a displacement of said crown relative to said headstock from one to the other of its extreme positions in a displacement of said clutch means from one to the other. other of their positions, said holding means acting on said transformation means to prevent the passage of said clutch means in said first position as long as said evaluated voltage does not reach said predetermined high threshold value, and to prevent the passage of said clutch means in said second position as long as said evaluated voltage does not reach said predetermined low threshold value.
  • the clutch automatically switches from one position to the other as soon as the conditions of tension in the end are met.
  • the first and second means of liberation may be confused at least in part.
  • the bottom of the capstan will designate the side thereof intended to be secured to a support, while the top of the winch will designate the opposite part of the capstan.
  • Such a capstan 10 comprises a frame 11 on which is movably mounted in rotation of a doll 12.
  • the frame 11 is intended to be secured, for example on the deck of a sailboat.
  • One end, one end of which is connected to a sail of the sailboat, can be wrapped around the headstock 12.
  • This capstan 10 conventionally comprises a reversible imprisonment device 13 at one end of the end to be wound around the headstock 12.
  • the capstan comprises an input shaft 14 mounted so that it can rotate in the frame 11.
  • the input shaft 14 comprises an upper end 141 in which a grooved portion 142 is provided, designed to cooperate with means for actuating the capstan.
  • actuating means may include a crank. Alternatively, they may include "a coffee grinder”.
  • the drive means may also be motorized.
  • the input shaft 14 is connected to a satellite carrier 15.
  • This satellite carrier 15 carries axes 16 on each of which a satellite 17 is mounted mobile in rotation. These satellites 17 mesh with a fixed internal gear 18 integral or not with the frame. The satellites 17 also mesh with a solar 19. This assembly forms a planetary gear train.
  • the satellite carrier 15 comprises a lower part on which a half-dog 150 is formed.
