Definitions

  • the present invention is part of the technical field of boat fittings, in particular mechanical devices for exiting and launching a load, such as an auxiliary craft, to or from a ship.
  • the invention relates more particularly to an improved platform for launching and lifting a boat tender, intended to be placed at the rear of a vessel and moved vertically by an operator relative to the vessel.
  • the platform of the invention integrates a retractable rotating and sliding gangway for disembarkation and/or access to a quay.
  • the invention also relates to a boat, such as a catamaran, on which such a hydraulic platform is incorporated.
  • ship annex we mean a secondary boat embarked in the carrier vessel, such as a motorized or non-motorized boat, an inflatable device, etc.
  • the vertical position of the platform is typically controlled by an operator on board, for example between a position adjacent to the deck of the ship and a position under the body of water.
  • the hydraulic support platform of the annex generally extends in a horizontal plane, parallel to the deck of the ship.
  • the platform is generally mounted on the boat via at least one mechanical arm (preferably via two parallel arms) pivotally mounted on the boat.
  • the Applicant has for example designed and implemented a vessel platform control device, described and illustrated in the European patent EP 3 279 077 B1 , making it possible to raise or lower the platform relative to the vessel while maintaining said platform substantially horizontal.
  • the control device described in this document notably comprises two elbow arms each equipped with a hydraulic cylinder, associated with a link mounted at one end on the extension rod of said cylinder.
  • the device described in this document further comprises flexible means of transmitting tensile force, such as hauling ropes.
  • the distances between the points of articulation and attachment of the various mechanical elements of the control device are dimensioned so specific, in order to ensure the horizontality of the platform throughout its vertical movement.
  • the international patent application published under number WO 2022/069595 A1 describes a functional improvement of the device for launching and removing the load from or to the boat.
  • the device described in this document comprises a single cylinder with an extension rod, capable of acting on additional control means of the rotational movement of the platform, here a rotation bar placed under the platform.
  • the vertical movement of the platform at the rear of the deck of the boat can in particular allow the descent or ascent of people between the boat and a dock. It is possible to equip the platform with a mobile walkway, or even a ladder, to facilitate this descent and ascent.
  • the walkway can be tilted vertically.
  • the variation in inclination of the gangway essential to adapt the gangway to the different possible quay heights, may require suspending the gangway from one or more davits, remaining permanently on the deck of the boat. This creates additional space on the deck of the boat, as well as additional weight on board.

  • the disembarkation and quay access gangway cleverly combines two functions in one, which frees up space in a vessel, in this case a boat, given that these two functions were provided until present by two distinct products.
  • the disembarkation and access gangway to the quay, integrated into the launching and lifting platform according to the invention, is retractable.
  • the walkway is thus almost invisible when it is in a retracted position in the floor of the platform, so as to preserve the aesthetics of the platform.
  • the gateway can easily be deployed and access a plurality of vertical and inclination positions, allowing it to thus adapt to various heights. of dock. Disembarkation and access of people is thus facilitated.
  • disembarkation and quay access gangway can be raised easily without necessarily activating the controls, so as to be able to absorb swell and adapt the level of the gangway to variations in sea level.
