Patent number: 8866032Abstract: The disclosure concerns an electrical switch for nautical equipment. The switch comprises electric actuation means, which in turn comprise at least one control button, able to be connected to an external electric circuit, and a housing of such electric actuation means. Advantageously, the switch also comprises a covering element that is moveable with respect to the housing between a first position, at which the button can be directly activated by the user by just inserting a finger into a suitable recess, and a second position, at which the covering element prevents direct access to the button and is itself moveable by the user in the direction towards the button for its activation. When the covering element is in the second position, the activation of the button can be obtained by pressing the covering element with a foot or with a hand.Type: GrantFiled: April 26, 2011Date of Patent: October 21, 2014Assignee: Harken Italy, S.p.A.Inventors: Mario Giordano, Pietro Dario Binda, Andrea Zanetti

Patent number: 7422196Abstract: The invention refers to a drive system of the servo-pneumatic type for activating/deactivating motion transmissions in sailing boats. The drive system of the invention is adapted to activate/deactivate motion transmission operating configurations, or for shifting from one motion transmission operating configuration to another one, when a drive is given by a crew member, much more rapidly than with the mechanical drive systems known in the art. The drive system of the invention can be used, for example, for activating/deactivating the motion transmission between pedestals and/or between pedestals and winches, or for driving the shift from one winch speed to another one, or to prevent the deactivation of a first winch speed when shifting from a first speed to a second speed, or also for driving any speed multiplier connected to the winches.Type: GrantFiled: June 3, 2005Date of Patent: September 9, 2008Assignee: Harken Italy S.p.A.Inventors: Francesco Binetti Pozzi, Andrea Merello

Publication number: 20020096672Abstract: A winch for sailboats comprises a stator body intended to be integrally mounted on a deck of a sailboat, and a rotor body intended to house a rope for manoeuvring the sailboat. The rotor body is coaxially and turnably fitted onto the stator body along a primary rotation driving shaft. The winch also comprises a secondary motion transmission shaft in meshing engagement with the rotor body and a plurality of gears, between the primary shaft and the secondary shaft, intended to transmit the motion to the rotor body with a predetermined reduction ratio. The gears are housed into a box intended to be arranged below the boat deck. During maintenance operations, to access the gears it is sufficient to remove the gearbox from below deck; in the meantime, the winch can still perform its function of rope deviation.Type: ApplicationFiled: January 25, 2001Publication date: July 25, 2002Applicant: Harken-ItalyInventors: Andrea Merello, Alberto Lozza
