Definitions
- the present invention relates to a moving gangway for a boat, comprising at least one gangway element, defining a passage surface for the transit of persons, and support means, which can be assembled fixedly to said boat and to which said gangway element is movably assembled.
- Conventional automated gangways are generally pivoted at one end to the body of the boat and have a control system, generally hydraulic, which can lower or raise them via one or more hydraulic cylinders controlled by a control unit actuated by an operator, so as to rest the other end of the gangway on the structure to which the boat is moored, for example a jetty.
- US-A-5 628 274 discloses a gangway of the type defined at the beginning, wherein the gangway is pivotally connected to the support means through a link.
- the moving gangway according to the invention is characterized in that it comprises connection means for connecting said gangway element to said support means in such a way that said gangway element can translate in a direction substantially perpendicular to said passage surface.
- FIG. 1 is a perspective view of a gangway for a boat according to the invention.
- FIG. 1 is a partial view in side elevation of the gangway of Figure 1.
- gangway 1 which can be assembled to a boat S, comprising one or more elongate gangway elements 2, 3 which define a surface P for the passage of persons between the boat S (a portion of which is shown in the figures) and a mooring structure, for example a jetty (not shown) .
- proximal and distal are used with reference to the point of assembly of the gangway 1 to the boat S.
- the proximal and distal gangway elements 2, 3 are arranged in such a way as to form a telescopic structure which can extend in the known manner to reach a predefined maximum length of extension.
- the proximal gangway element 2 has a box-like structure into which the distal gangway element 3 can slide.
- a fluid-actuated cylinder 4 is mounted, whose bottom end is pivoted at 5 to the body of the box-like element 2 and whose rod (not shown) is secured to the distal gangway element 3.
- this arrangement is only an example, the invention also being suitable for a gangway with a single gangway element.
- the gangway 1 also comprises a stationary support structure 10, comprising a flange portion 11 which can be fixed at a predefined point on the boat S, for example by means of bolts 11a, and a projecting portion 12 extending substantially perpendicularly to said flange portion 11.
- the projecting portion 12 of the support structure 10 has a base wall 13 from whose opposite sides extend, in a substantially vertical direction, side walls or wings 14 and 15.
- the side walls 14 and 15 are also connected to the flange portion 11 of the support structure 10.
- the side walls 14 and 15 have through slots, 16 and 17 respectively, made in them, these slots running substantially perpendicularly to the flange portion 11.
- the lower end of a lever 21, 22, respectively is pivoted to the proximal end of each side wall 14, 15, at the pivot points 21a and 22a.
- Each lever 21, 22 is also pivoted to a lever 23, 24, respectively, at a pivot point 21b and 22b.
- the lower ends of the levers 23 and 24 are pivoted to a pin 31, at opposite ends of said pin, at the pivot points 23a and 24a, respectively.
- the pin 31 runs transversely to the direction of extension of the support structure 10 and its opposite ends pass through the slots 16 and 17, respectively.
- the free end of rods 32 and 33, respectively, of fluid- actuated cylinders 34 and 35 are pivoted to the portions of the pin 31 which project laterally outwards from the side walls 14 and 15.
- the cylinders 34 and 35 are also pivoted at the bottom to the distal end of the support structure 10, at pivot points 34a and 35a respectively.
- a moving support structure 40 is arranged above the stationary support structure 10, the proximal gangway element 2 being assembled to said moving support structure.
- This support structure 40 has a base wall 43, from whose opposite sides extend, in a substantially vertical direction, side walls or wings 44 and 45 (the wall 45 is not visible in the figures) .
- the side walls 44 and 45 have respective through slots 46 and 47 made in them (the slot 47 is not visible in the figures) , these slots running parallel to the slots 16 and 17 in the stationary support structure 10.
- the upper ends of the levers 23, 24, respectively, are pivoted to the proximal end of each side wall 44, 45, at the pivot points 23c and 24c (the pivot point 24c is not visible in the figures) .
- the upper ends of the levers 21 and 22 are pivoted to a pin 51, at opposite ends of this pin, at pivot points 21c and 22c, respectively (the pivot point 22c is not visible in the figures) .
- the pin 51 runs transversely to the direction of extension of the support structure 40 and its opposite ends pass through the slots 46 and 47, respectively.
- the levers 21, 22 and 23, 24 are the same length between their opposite end pivot points, and their intermediate pivot points 21b and 22b are located half way along their length.
- the overall structure of the gangway 1 is also substantially symmetrical with respect to a vertical plane passing through the centre line of the gangway 1.
- the slots 16, 17, 46, 47 are aligned with the pivot points 21a, 22a, 23c and 24c, respectively, while the pivot points 23a, 24a, 21c, 22c can move in translation along the slots 16, 17, 46 and 47, respectively.
- the levers 21, 22 and 23, 24 perform overall a pantograph-type movement, commanded by the cylinders 34 and 35, in which the moving support structure 40 can move in translation in a vertical direction, marked V in Figure 2, i.e.
- the extension of the slots thus determines the vertical path of the moving support structure 40.
- the distal ends of the slots are arranged at a distance from the pivot points with which they are each aligned in such a way as to allow the gangway element 2 to be lowered until it comes to rest on stops 61, 62 provided on the stationary support structure 10.
- the gangway 1 described herein can also perform another kind of movement.
- the proximal gangway element 2 is pivoted, at 71, to the moving support structure 40 in such a way that it can rotate in a vertical plane parallel to the direction of extension of the gangway 1, in the direction indicated by the arrow R.
- the tilting movement of the gangway element 2 with respect to the moving support structure 40 is commanded in the known manner by a fluid- actuated cylinder 80, whose rod 81 is pivoted at its free end to the proximal element 2 of the gangway 1, at 82.
- the bottom end of the cylinder 80 is pivoted to a bracket 85 fixed to the moving support structure 40.
