A furling arrangement (10) for furling/unfurling a sail (104), comprising a two-way ratchet mechanism with rotatably stored, spring loaded ratchet pawls and a control means (20) for application of torque to a driveable sheaving unit. A pre-loaded centering spring (35) keeps a sail end terminal (30) and the sheaving unit, comprising movement restraining elements for cooperation with sail end terminal blocking elements, in a neutral state in preventing the sail end terminal (30) from changing rotation direction. In the neutral state the ratchet pawls block rotation in a first direction. Through application of a torque to the sheaving unit in said first direction, it will rotate slightly with respect to the sail end terminal (30) against action of the pre-loaded centering spring, making temporary receiving slots available, and until movement restraining elements and the sail end terminal blocking elements engage. Through application of further torque, the sail end terminal (30) will rotate with the sheaving unit allowing the ratchet pawls to flip over in the temporary slots, enabling rotation in said first direction instead.

The outer circumferential element has a contact surface (Hi) adapted to bear against the upper side of a deck, the recess (13) is a through recess and comprises a receiving opening facing away from the outer circumference of the circumferential element forming a limiting surface (12) and through which a fastening element can be introduced. The mounting arrangement (100) furthermore comprises a separate second mounting element (20) which is adapted for being arranged on the first mounting element (10) and to form a limiting element for a fastening element introduced into said recess (13), at least against axial movement.
The present invention relates to a line winch (1) and to a method to pull in and let out line. Line winch (1) has a rotatably mounted winch drum (2). Line (3) is wound up by means of a driving device, for example a crank (V) or a motor, by means of which the winch drum (2) can be rotated at different speed in a first direction in order to pull in the line (3), and in a second direction in order to let out line (3). Line (3) under load is pulled in on to the winch drum (2) in that a force or a torque is directed via a driving shaft (5) from the driving device in a first direction, whereby a to the driving shaft connected cone coupling (27, 29) provided with an internal trapezoid thread (16) is tightened, so that a gear wheel (33) mounted on a shaft (32) is actuated, and by meshing with a gear wheel (35), which is mounted on a shaft (A), rotates said wheel, so that the winch drum (2) is operated in a first direction directly or indirectly by means of the gear wheel (35) and another gear wheel (39), which is placed on the shaft (A), by means of a free wheel (35a) acting between the gear wheels (35, 39). Loaded line (3) is let out in that the driving device is actuated in a second driving direction, whereby the cone coupling (27, 29) 'is released and allows that line is let out until the load of the line again tightens the cone' coupling by means of the trapezoid thread when actuation of the driving device in the second driving direction is terminated.
The instant invention concerns a proceeding and an arrangement in connection with a winch for a sheet or a halyard on a sailing boat. This is, besides for sheeting-in, constructed to also allow veering-out of sheet or halyard rope arranged thereon by means of means that normally otherwise are intended for sheeting-in, more precisely a crank possibly having an appurtenant transmission integrated in the winch or the corresponding motor drive and appurtenant transmission, for driving of a drum belonging to the winch and a self-tailing unit arranged at the upper end of the same. The last-mentioned one has upper and lower rope guide rings as well as means in the form of an expedient arm for directing the rope into and out of the self-tailing unit in a controlled way. The invention embraces suspension and spring-mounting means for at least one of the rope guide rings that are arranged in such a way that this/these obtain(s) a mutually static and dynamic motion pattern. This pattern is such that, in connection with forcing apart the rope guide rings somewhere along the periphery thereof, for instance, by the arrangement of a rope between the same, the corresponding opposite portions of the rope guide rings automatically approach each other, for clamping of the rope arranged therebetween.
A procedure and device in order to, at a rope winch (L), allow a winching in at two or more speeds, as well as a winching out of a sheet. The device embodies a rotatably mounted rope drum (38) and a shaft (6) driving the same via a transmission (7-14), around which drum (38) a rope is windable, as well as forcing means, such as a crank (1), for allowing the rope drum (38) to be driven by means of the driving shaft (6) in a first direction using at least two different gearings. The loosening of the sheet to an adjusted extent is allowed by the fact that means (5, 35) in/on the crank are actuated at the same time as cranking is carried out, a drive gear (7) of the transmission, which in the normal case drives in the same direction as the crank is cranked, by means of forcing means (17) being brought out of driving engagement with the input shaft (6), the torque nevertheless applied to the input shaft instead being used to release the drive gear (7) from driving engagement in such a manner that the driving coupling between the crank (1) and the transmission (7-14) is temporary disabled to transfer torque, wherein rope wound on the drum of the winch can run out under load from the same.
A procedure at and a device for a rope winch (1), embodying a rotatably mounted rope drum (2), around which a rope (3), by force amplification, is windable by means of forcing means, e.g., a crank or one or more motors (27). The rope drum (2) is turned either in a first direction to haul in the rope (3) or in a second direction to veer out rope (3) to an adjusted extent. Upon hauling in of rope (3) onto the drum (2), an inner cone (18) in a double cone coupling is driven by an outer cone (12) therein urged by a ratchet cone of a ratchet wheel (15) in such a manner that a trapezoidal thread (19) is tightened so that the tightening force between the inner and outer cones overcomes the torque provided by the rope (3) via the rope drum (2) and drives a transmission of the winch in such a way that rope (3) is brought in. Upon veering out of rope (3), the same outer cone (12) allows the inner cone (18) to be lifted via the trapezoidal thread (19) so that the tightening force between the ratchet cone and the outer cone (12) is reduced so much that the force from the rope (3) temporary allows the transmission to veer out rope (3) to an adjusted extent in spite of the ratchet being urged against the ratchet cone.
Method and a device (1 ) at a motor driven line winch (2) for sailing boats comprising a rotatably mounted line drum (3) around which a line (4) for sail and halyard is windable. According to the invention, more than one electrical motor is arranged in order to in different manners in different engagement patterns be possible to be coupled together in order to thereby actuate the winch (2) by different desired power and be able to optimize the total efficiency of the device.
The invention relates to a device (10) at a cleat (1) for a sailing boat in order to provide detachable locking of the line (3) to a sail, a rig or the like, where the line (3) runs over a sheave (2) on an elevated level and having cleat (1) for locking the line (3) situated at a distance from the deck of the boat. According to the invention, the line (3) is arranged to run over a sheave (2), which is provided with ratchet back stop (5). The line (3) is in that connection arranged to directly co-operate with a movably actuatable mechanism (14), which is arranged to activate the ratchet back stop (5). The mechanism (14) is formed of at least one pivotably mounted main arm (4), and said mechanism (14) is arranged to activate the ratchet back stop (5), the mechanism (14) being arranged to, upon fixed load of the line (3, 3A), which goes down to deck and by means of which the sail (9) is hoisted, actuate the main arm (4) to connect ratchet back stop function (5) on the sheave (2) and in that connection prevent the pulling backwards (7) of the line toward the sail (9).
