A retractable warping winch with a supporting housing, adapted to be stably fixed to a deck of a vessel at an opening thereof, and a bell, including a base and a drum integral to each other. The bell is movably supported by the housing so that it can vertically shift therein between an extracted working position and a retracted rest position. The winch also includes a driving mechanism to rotate the bell, including a motor and a transmission. The driving mechanism includes a drive hub mounted in the housing. The base of the bell is mounted in the drive hub to be rotatably integral therewith and free to axially shift with respect thereto. The drive hub is mounted in the housing to be rotatably free and axially constrained thereto. The motor is mounted on the housing, externally and laterally thereto.

Retractable warping winch

The invention describes a winch for nautical use or for devices for lifting and lowering on a rope, comprising a fixed stator body and a rotor body fixedly connected to the stator body. The rotor body is able to rotate around a longitudinal axis to wind a rope on its outer surface. The winch is provided with a self-tailing device in turn comprising two half-pulleys, a lower half-pulley and an upper half-pulley, mounted opposite one another and coaxial to the rotor body. The two half-pulleys, at the upper portion of the outer surface of the rotor body, define a circumferential throat intended to at least partially house a winding of the rope. One half-pulley is fixed with respect to the rotor body and the other half-pulley is moveable parallel to the longitudinal axis to vary the dimensions of the circumferential throat. Advantageously, the winch comprises a device for adjusting the position of the mobile half-pulley along the longitudinal axis; the adjustment device is able to be activated by the user in real time and in all conditions of use of the winch.

Winch provided with adjustable self-tailing and relative operation

The invention describes a winch () for nautical use or for devices for lifting and lowering on a rope, comprising a fixed stator body () and a rotor body () fixedly connected to the stator body. The rotor body is able to rotate around a longitudinal axis(a-) to wind a rope on its outer surface. The winch is provided with a self-tailing device () in turn comprising two half-pulleys (), a lower half-pulley () and an upper half-pulley (), mounted opposite one another and coaxial to the rotor body. The two half-pulleys, at the upper portion of the outer surface of the rotor body, define a circumferential throat () intended to at least partially house a winding of the rope. One half-pulley is fixed with respect to the rotor body and the other half-pulley is moveable parallel to the longitudinal axis to vary the dimensions of the circumferential throat. Advantageously, the winch comprises a device (-) for adjusting the position of the mobile half-pulley along the longitudinal axis; the adjustment device is able to be activated by the user in real time and in all conditions of use of the winch.

The invention regards to a portable ascender device () on a rope () comprising an actuation element (), manual or motor-driven, a nautical winch () provided with a self-tailing (), rotated by the actuation element (), and at least one first forced passage () of the rope () in proximity to the winch (). The first forced passage () is arranged upstream of the winch () with respect to the rope () winding direction. A method for hoisting oneself by means of such device () along a vertically stretched rope (), and two methods for descending along the rope () by means of the same device (), respectively in active mode and in passive mode, are also described.

Rope ascender device and method for use thereof

A device () for actuating sheets of sailing boats comprises a pulling element () for a sheet () and an actuator () connected to the pulling element () for causing the motion thereof. The actuator () comprises a screw () and a nut () engaged with each other, wherein one from the screw () and the nut () is rotated and the other translates linearly. A boom () of a sailing boat () provided with the device () for actuating sheets of the invention is also described.

Device for actuating sheets of sailing boats

A pedestal () for a sailing boat comprises a casing () and inside such a casing (): at least one driving wheel () associated with a motion input shaft (), at least one driven wheel () associated with a motion output shaft () and at least one motion transmission element () from said at least one driving wheel () to said at least one driven wheel (). The pedestal () further comprises, also inside the casing (), a speed variation system selectively activatable to vary the rotation speed of the motion output shaft () with respect to that of the motion input shaft ().

Pedestal for a sailing boat

A fixing group of a watercraft appliance for the attachment thereof to an outer side of a deck wall of a boat comprises a base of the watercraft appliance and at least one seat formed in the base and suitable for receiving a respective threaded fastening element, so that said element has a free end projecting from the base for insertion into a respective through hole formed in the deck wall, so as to be accessible from the inner side of such a deck wall for fixing the watercraft appliance to it. The at least one seat comprises an access at a peripheral surface of the base and a retaining portion suitable for cooperating through shape coupling with said threaded fastening element to prevent the rotation and axial sliding thereof with respect to the base. The invention also refers to a method for attaching a watercraft appliance comprising said fixing group to a deck wall of a boat by means of threaded fastening elements.
