Definitions
- the present invention relates to a telescopic gangway for a floating navigation unit, capable of allowing the comfortable use thereof even in the case in which the gangway walkway surface is substantially misaligned with respect to a dock plane, and also in the case in which a user wishes to comfortably move from the gangway walkway surface to an immersion position and vice versa.
- Telescopic gangways are well known in the nautical field.
- FR 2 862 275 A1 discloses a structure having an arm inclinable under action of a hydraulic jack around an axle carried by a carriage.
- the arm carries two articulations at its opposite end, where the articulations support a metallic structure carrying a platform.
- the platform is automatically maintained parallel to center line of the carriage by a mechanical system comprising two connecting rods, when the inclination of arm is modified.
- EP 1 854 715 A1 discloses a telescopic walkway for boats with integrable and entirely foldaway structure, of the type suitable for extending between at least one portion of stern platform of the boat and at least one mooring quay or wharf, comprising at least one profile, having substantially parallelepiped section and contained inside the stern platform, which can be actuated to lift by means of a plurality of cylinders, possibly coupled with plunger pistons, or by means of a pantograph system; inside the parallelepiped profile at least one ladder is contained, able to slide horizontally and orientable upwards and downwards, which can be used both to go into the water and for mooring on the quay or wharf.
- WO 2014/182173 A1 discloses a ramp for forming a temporary transport connection between a vessel and a quay is disclosed.
- the ramp comprises a frame having a plurality of elements that shifts between a folded position in the vessel, and an extended position, and where the innermost end of the frame is hingedly mounted in the vessel.
- the ramp comprises means that allow the frame to be tilted.
- the ramp has a plurality of telescopic elements which slides in and out of the frame.
- the telescopic gangways comprise at least two elements telescopically engaged in translation to one another, between a closed configuration which corresponds to a minimum length, and an open position which corresponds to a maximum length.
- the telescopic gangways protrude in a cantilever manner, with respect to the hull of the floating navigation unit, while in the closed position they are generally withdrawn inside the hull and are hidden from view.
- the telescopic gangways define a walkway surface, which is a plane adapted to be treaded on by an individual who walks along the gangway.
- the gangway therefore, is used to allow the passage of an individual from the floating navigation unit to the dock and vice versa.
- This rotation varies the slope of the walkway surface, therefore it may only be restricted within a rather limited angle with respect to a horizontal plane, to allow a user to walk on it safely.
- the known telescopic gangways do not allow a user to pass on them when the difference in height between the connection point of the gangway to the hull and the dock plane is significant.
- the known telescopic gangways even if they may rotate at a predetermined angle with respect to a horizontal plane, do not in any way allow a user who is in the water to access on board the floating navigation unit by passing, or walking on the gangway.
- Moving platforms are also known which allow to move part of a stern platform of the floating navigation unit up to an upper or lower level with respect to a resting position. However, even if moving the platform, they do not allow to form, at the same time, a continuous treadable plane from the hull of the floating navigation unit to the dock plane, easily used by a user, simply by walking.
- the structure itself of the floating navigation unit must be reinforced and redesigned, to support the considerable loads generated by the own weight of the movable structure and of the bulky handling machinery, but also to counteract the high moment value of the forces generated by the significant weight of the platform and by a significant arm value of the applied forces.
- the need is therefore felt to provide a telescopic gangway capable of forming a continuous walkway between a connection point of the gangway to the floating navigation unit and a free end of the gangway, even if the difference in height between the connection point of the gangway and the level of the dock is significant, avoiding that said walkway has a significant slope.

WO 2014/182173 A1 discloses a ramp for forming a temporary transport connection between a vessel and a quay is disclosed. The ramp comprises a frame having a plurality of elements that shifts between a folded position in the vessel, and an extended position, and where the innermost end of the frame is hingedly mounted in the vessel. The ramp comprises means that allow the frame to be tilted. In one embodiment, the ramp has a plurality of telescopic elements which slides in and out of the frame. - The telescopic gangways comprise at least two elements telescopically engaged in translation to one another, between a closed configuration which corresponds to a minimum length, and an open position which corresponds to a maximum length.
- In the open position, the telescopic gangways protrude in a cantilever manner, with respect to the hull of the floating navigation unit, while in the closed position they are generally withdrawn inside the hull and are hidden from view.
- The telescopic gangways define a walkway surface, which is a plane adapted to be treaded on by an individual who walks along the gangway.
- The gangway, therefore, is used to allow the passage of an individual from the floating navigation unit to the dock and vice versa.
- In order to adapt the gangway to a dock plane which is vertically displaced with respect to a connection point of the gangway with respect to the hull, rotating the entire gangway is known, when it is in the open position, along a vertical plane, about a horizontal axis, transversal to a telescopic lengthening axis of the gangway.
- This rotation, however, varies the slope of the walkway surface, therefore it may only be restricted within a rather limited angle with respect to a horizontal plane, to allow a user to walk on it safely.
- Therefore, the known telescopic gangways do not allow a user to pass on them when the difference in height between the connection point of the gangway to the hull and the dock plane is significant.
- Furthermore, the known telescopic gangways, even if they may rotate at a predetermined angle with respect to a horizontal plane, do not in any way allow a user who is in the water to access on board the floating navigation unit by passing, or walking on the gangway.
- Similarly, such known telescopic gangways do not allow the user to comfortably dive simply by walking on the walkway surface of the gangway itself.
- Moving platforms are also known which allow to move part of a stern platform of the floating navigation unit up to an upper or lower level with respect to a resting position. However, even if moving the platform, they do not allow to form, at the same time, a continuous treadable plane from the hull of the floating navigation unit to the dock plane, easily used by a user, simply by walking.
- Among other things, such known movable platforms often have articulated structures, which are mechanically complex, which require actuators of great power and size, and which are therefore quite heavy.
- Furthermore, such known movable platforms require redesigning the stern platform of the floating navigation unit, both structurally and aesthetically. In fact, a compartment must be obtained inside the stern platform, housing an additional mechanical and hydraulic apparatus to move the platform itself.
- The structure itself of the floating navigation unit must be reinforced and redesigned, to support the considerable loads generated by the own weight of the movable structure and of the bulky handling machinery, but also to counteract the high moment value of the forces generated by the significant weight of the platform and by a significant arm value of the applied forces.
- The need is therefore felt to provide a telescopic gangway capable of forming a continuous walkway between a connection point of the gangway to the floating navigation unit and a free end of the gangway, even if the difference in height between the connection point of the gangway and the level of the dock is significant, avoiding that said walkway has a significant slope.
- The need is also felt that the assembly of such gangway to the floating navigation unit does not require any structural or aesthetic modification to the floating navigation unit, with respect to the assembly of a conventional gangway.
- It is the object of the present invention to devise and provide a gangway for a floating navigation unit, which allows to meet the aforesaid requirements and to at least partially overcome the drawbacks complained above with reference to the background art.
- In particular, it is the object of the present invention to provide a telescopic gangway for a floating navigation unit which allows to form a continuous walkway between a connection point of the gangway to the floating navigation unit and a free end of the gangway, even if the difference in height between the connection point of the gangway and the level of the dock is high, avoiding that said walkway has a significant slope.
- It is another object of the present invention to provide a telescopic gangway for a floating navigation unit which allows a user to move from the floating navigation unit to a dock plane even in the case in which the difference in height between the connection point of the gangway and the level of the dock is significant, thus avoiding said gangway requiring cumbersome and heavy movement actuation apparatuses.
- It is another object of the present invention to provide a telescopic gangway for a floating navigation unit which allows a user to have an easy access from the sea to the floating navigation unit and from the floating navigation unit to the sea, along said gangway.
- Furthermore, it is an object of the present invention to provide a telescopic gangway for a floating navigation unit capable of allowing the assembly of such gangway to the floating navigation unit, thus avoiding requiring any structural or aesthetic modification to the floating navigation unit, with respect to the assembly of a conventional gangway.
- It is a further object of the present invention to provide a telescopic gangway for a floating navigation unit capable of being replaced by a conventional gangway of a pre-existing floating navigation unit, thus avoiding making any aesthetic and/or structural modification to such floating navigation unit.
- These and further objects and advantages are achieved by a telescopic gangway for a floating navigation unit, as well as by a floating navigation unit comprising said telescopic gangway, in accordance with the independent claims.
- Further objects, solutions and advantages are present in the embodiments described below and claimed in the dependent claims.
