Definitions
- Capstan comprising means for evaluating the voltage of a wound end around and means for automatically selecting at least one speed as a function of said voltage.
- the field of the invention is that of the design and manufacture of nautical equipment.
- the invention relates to a capstan intended to be secured to a sailboat for tensioning an integral end of a sail.
- This type of capstan is commonly referred to as a "winch”.
- Winches are commonly used on sailboats in order to allow their crew to tension the ends connected to the sails.
- a winch conventionally includes a frame housing a drive shaft, a gearbox.
- a doll connected to said shaft via the gearbox, is rotatably mounted on the frame.
- winches There are essentially two types of winches: two-speed winches and three-speed winches.
- the first gear is the one that allows to wrap the tip as quickly as possible.
- the higher speeds respectively allow to wind up the tip less quickly than in the previous speed but exerting less force on the crank so as to compensate for the fact that as the end is wrapped around the winch, its voltage increases.
- shifting is achieved by a teammate by reversing the direction of rotation of the crank.
- the passage from the first to the second speed is obtained, by a teammate, by reversing the direction of rotation of the crank, then the passage from the second to the third speed is obtained by the crew member by acting, if necessary, on a push button provided for this purpose on the winch and reversing the direction of rotation of the crank.
- the current winches are effective. They make it possible to tension one end while adapting the effort to be provided for this purpose by a team member given the implementation of a gearbox.
- the winches of the prior art have the disadvantage of requiring to reverse the direction of rotation of the crank and to actuate a push-button provided on the winch. This tends to complicate maneuvering crew members, moving in a difficult context (rough sea, crowded bridge).
- the team members do not generally wind up one end around the doll of a winch by operating the crank at the first speed, then at the second speed, then if necessary at the third speed. moving from the lower to the higher gear when their force no longer allows to wind the end to the lower gear.
- a certain tension is exerted on the end in first gear
- This action is commonly called "pumping" in the field of sailing. This makes it possible to reduce the angle of movement of an arm around the winch and the arm to exert a force on the winch in an angular range in which it is the most powerful.
- European patent application EP-A1-0 159 095 discloses a three-speed winch in which the passage from one speed to another is obtained by reversing the direction of rotation of the crank without it being necessary. to act on a button to go from second to third gear. According to the technique described, a rotation of the crank clockwise allows to operate the winch in first gear, a rotation of the crank counterclockwise allows to operate the winch in second gear, then a rotation of the crank again in clockwise allows to operate the winch in third gear.
- the technique described in this document has the advantage of allowing to engage the third speed by simply reversing the direction of rotation of the crank without the need to operate in addition to a push button.
- This technique has the disadvantage of not allowing the crew to pump between the first and second speeds and between the second and third speeds.
- the current winches also do not allow to adapt, the power of the arm of the team member in charge of the rotation of the crank of the winch, the passage of pumping between the first and second speeds pumping between the second and third speeds .
- Gear transmissions provide, depending on the manner in which they are implemented, reduction ratios or multiplication ratios.
- the ratio of a transmission is a reduction ratio
- the speed at the output of the transmission is lower than the input speed while the output torque is greater than the input torque.
- the ratio of a transmission is a ratio of multiplication the output speed is greater than the speed of entry.
- the torque generated on the doll for wrapping a tip is greater than the torque exerted by a team member on the crank for winding process, regardless of the speed engaged.
- the winding speed of the tip at the first speed is slow while the tension in the tip is low (usually a crank turn corresponding to half a doll turn).
- teammate puts the end around the doll by hand by pulling on the free end thereof to accelerate the tensioning of the end.
- the current winches therefore do not allow both to provide a rapid winding speed of the end and large winding torques.
- No winch can also adapt the speed ratio to the tension in the end.
- the invention particularly aims to overcome these disadvantages of the prior art.
- an object of the invention is to provide, in at least one embodiment of the invention, a capstan which makes it possible to adapt at least one speed to the tension in the end wrapped around.
- Another objective of the invention is to provide, in at least one embodiment, such a capstan that allows a crew member to automatically switch from a pumping between a first and a second speed then between the second and a third gear only by reversing the direction of rotation of the crank.
- Another object of the invention is to provide, in at least one embodiment, such a capstan in which it is possible to adapt to the strength of the crew member the passage of a pumping between the first and the second speed. then between the second and the third gear.
- Another object of the invention is to implement, in at least one embodiment, such a capstan in which the selection of at least one speed is obtained automatically taking into account the tension of the end wound around.
- An object of the invention is to provide, in at least one embodiment, a capstan in which the passage from one speed to another is obtained only by acting on the crank without the need to actuate other control means such as a push button.
- the invention also aims to provide, in at least one embodiment, such a compact capstan.
- Another object of the invention is to propose, in at least one embodiment, such a capstan which is ergonomic.
- Yet another object of the invention is to provide, in at least one embodiment, such a capstan which is inexpensive.

- the transition ring 40 integral with the lifting pins 39, follows the same movement, as is the lifting ring 42.
- the lifting ring 42 acts on the pusher element 43 via the spring
- the flange 431 then acts on the ends 184 of the pawls 183 of the one-way clutch 18. These pawls 183 are then maintained in their position in which they do not cooperate with the second element 182 of unidirectional clutch 18.
- the first 181 and second 182 clutch elements unidirectional 18 are not connected in rotation.
- the third gear is thus selected. However, as the crew continues to rotate the actuating means in the opposite direction of clockwise, the capstan will be implemented at the second speed, the third gear being preselected.

This adjustment is obtained by more or less screwing the screw 35 in the tapping 36 of the doll 12. The more the screw 35 is tightened in the tapping 36, the greater the tension of the tip must be important for the third speed to be cut . Conversely, the less the screw 35 is tightened in the tapping 36, the less the tension force of the tip will be important for the third gear to be selected.
- the tension in the end from which the third gear will be selected can therefore be adjusted according to the physical capabilities of the crew member to handle the capstan.
- the adjustment can be made so that the effort it will have to provide to wind the end to the second speed before the third gear is selected is average. If the teammate has a better physical condition, the adjustment can be made so that the effort it must provide to wind the end to the second speed before the third gear is selected is more important.

- the crew puts the end into tension by pumping between the second and the third gear.
- the capstan according to the invention therefore makes it possible to pass:
- the box is a three-speed gearbox
