Definitions
- This invention relates to a gangway for pleasure boats or harbour craft.
- the invention relates to a gangway, for example installable on the sides of pleasure boats, and conceived to be mobile and extendable, so as to be able to pass from a retracted or rest configuration to an extended or use configuration, and vice versa, by means of a telescopic mechanism.
- gangways are hooked to the boat and are extended when it is necessary to embark any passengers, in order to pass to a configuration of use starting from a configuration of rest, and vice versa.
- gangways are permanently fixed to the boats, and are moved between the rest configuration and the configuration of use by suitable devices and moving systems.
- the main aim of the invention is therefore to provide a gangway for boats which solves the above-mentioned drawbacks.
- an aim of the invention is to provide a gangway for boats equipped with a movement system that is simple to construct and reliable with respect to the prior art.
- Another aim of the invention is to provide a gangway with reduced overall dimensions, especially when this is not in use.
- a further aim of the invention is to provide a gangway for boats having a substantially zero environmental impact.
- an aim of the invention is that of providing a gangway which is easy and economical to make and use, by virtue of the advantages achieved.
- the gangway 100 is constructed according to a modular structure, comprising three main sections.
- a first section 101 which can be fixed to a boat (not shown) through plates 10, defines a cavity 90 inside it.
- the cavity 90 communicates with the external environment through a first open end 111 of the first section 101; the first end 111 faces the outboard of the boat, and has a door 91 which can be opened or closed as required.
- the space identified by the cavity 90 has the function of housing a second section 102 and a third section 103 of the gangway 100.
- the second section 102 is fixed in a second end 112 thereof to a support structure 200, which is movable slidably inside the cavity 90 along a main direction, in this case a horizontal direction.
- the fixing of the second section 102 to the support structure 200 is obtained by means of a hinge 210, around which the second section 102 itself can rotate according to a predetermined angle.
- the second end 112 is also open, communicating with the cavity 90 of the first section 101.
- the second section 102 has an inverted U profile having two lateral guides 120, so as to define an underlying space in which the third section 103 can slide along the guides 120 themselves.
- the movement of the third section 103 occurs through a third open end 113 of the second section 102 itself.
- the three sections 101, 102, 103 are therefore connected to each other to form a telescopic structure.
- the sliding movement of the third section 103 through the opening 113 of the second section 102 is regulated by a movement system comprising at least:
- the spiral nut 1 is fixed to the third section 103, and is slidingly constrained to the worm screw 2.
- the worm screw 2 is in turn constrained to the Cardan joint 3, specifically to its first fork 31.
- a reducer 41 supporting the electric motor 4, which is connected to the first fork 31 by means of a shaft 42, integral with the second fork 32 of the Cardan joint 3 itself; the two forks 31, 32 are connected to each other by a cross journal 33.
- the nut 1, the screw 2 and the joint 3 constitute a kinematic chain connecting between the motor 4 and the third section 103 of the gangway 100.
- the motor 4 when activated, causes the rotation of the shaft 42, which in turn rotates the screw 2 through the Cardan joint 3.
- the rotation of the screw 2 causes the sliding on the relative outer surface of the spiral nut 1, along a direction X coinciding with the axis of the screw 2 itself.
- the clockwise rotation of the screw 2 generates a translation of the third section 103 towards the joint 3, so that it falls inside the second section 102, bringing the gangway 100 into the retracted or rest configuration.
- the support structure 200 can be made to slide inside the cavity 90 of the first section 101, substantially in such a way as to eliminate the overall dimensions of the entire structure when not in use.
- the presence of the hinge 210 advantageously allows the gangway 100 to be inclined according to a greater or lesser angle with respect to the horizontal, in such a way as to be able to accommodate any unevenness of docks or landing surfaces not perfectly aligned with the first section 101 (as shown in Figures 3 and 5 ).
- Cardan joint 3 ensures that the sliding of the third section 103 is not compromised when the sections 102 and 103 are inclined and the X axis is misaligned with respect to the axis of rotation of the shaft 42 (as shown in Figures 4 and 6 ).
- the gangway 100 can comprise stanchions 50 positioned on one or both of its sides, for fixing any handrails.
