Definitions

  • the invention relates to a boat, particularly to a service-boat for crafts, ships, or the like, having at least a central part of the hull made like a rigid shell and at least two peripheral floating elements.
  • the invention provides a boat of the above mentioned kind, having peripheral floating elements which are secured to the central rigid part of the hull in an overturning way, alternatively in an active position, in which they are placed outside over the rigid part of the hull and in a storage or transport position, in which the said floating elements are placed inside the said central, rigid part of the hull.
  • the floating elements can be locked in the active position by means of any releaseable means.
  • floating elements it is preferably to use floating bodies formed by substantially cylindrical, inflatable chambers of rubberized canvas.
  • two floating elements are provided, which are hinged along one longitudinal edge, at the respective broadside of the central rigid part of the hull, preferably at least along a straight section of it.
  • the hinging means can be of any kind and for example of a kind similar to the usual hinges of metallic material or of plastic, too.
  • the floating elements are hinged to the rigid part of the hull by means of longitudinal stripes of rubberized canvas made of one or more layers and being glued on one side to the floating element and on the other side to the adiacent longitudinal edge of the rigid part of the hull.
  • the hinging means can be secured directly to the inflatable floating elements of rubberized canvas or with the interposition of stiffeners, as longitudinal members, or the like, which are incorporated in or fixed to the said floating bodies of rubberized canvas. This is particularly advantageous when the boat has considerable dimensions, like in the case of using it as a pleasure-boat, or when particular qualities of stability and strength are required.
  • the transversal dimensions of the boats is notably reduced, in turning over the floating elements inwards, inside the rigid part of the hull.
  • the said rigid part of the hull can show a width substantially corresponding to the double of the diameter of the floating elements.
  • the boat is used essentially as a pleasure-boat, particularly of the kind known with the denomination of rubber-boat, then it is advantageous to provide a central rigid part of the hull showing a width greater than the double of the diameter or the transversal dimension of the lateral floating bodies.
  • a free space is left between the two floating bodies for the stable or removable fittings and equipments, as for example the steering devices and the associated drivers' compartment, the different safety equipments and other kinds of equipments.
  • the construction and the building of the before described boat according to the invention are simple and less expensive.
  • the boat shows a reliability equal to that of the similar conventional boats.
  • the floating elements overturned inside the shell, fill up a substantial part of the shell itself, avoiding also the disadvantage of burdening due to the considerable amount of water taken aboard by shipping waves in the case of following sea or in consequence to a lateral heeling of the boat.
  • Figure 1 shows a perspective view of a first embodiment of the boat according to the invention.
  • Figures 2 and 3 are respectively a side view and a top view of the locking means for the floating elements in the active floating position.
  • Figure 4 is a cross sectional view of the boat according to the preceding figures and with the floating elements in the active and inactive position.
  • Figure 5 is a perspective view of a second embodiment of the boat according to the invention.
  • Figure 6 is a cross-sectional view of the boat according to fig. 5.
  • Figures 7 and 8 show the boat according to the invention in its position of transport, being suspended to a particular device for lifting and lowering away a boat, particularly advantageous for thr sailing boats.
  • a boat particularly a service-boat for crafts, is formed by a rigid central part 1 of the hull comprising the part of the keel or underbody and the central part of the bow and of the stern.
  • the rigid part of the hull can be built of any material, for example of plastic, of light alloy, or the like.
  • the broadsides of the boat are formed by two inflatable lateral floating elements, wich are tubular shaped and of rubberized canvas and which extends themselves along a substantial section of the broadsides of the boat, the section being substantially straight.
  • the floating elements 2 are hinged to the rigid part of the hull, i. e. to the longitudinal side edge 3 of the rigid parti 1 of the hull corresponding substantially to the lower edge of the broadsides, in an overturning way from the inside to the outside and viceversa, around an axis coinciding with the said longitudinal edge 3.
  • each floating element 2 is provided by means of a longitudinal stripe 4 of rubberized canvas, or the like, formed by one or more layers, this stripe reaching from the bow to the stern of the boat and being glued to the adjacent, facing, internal bands of the floating elements 2 and of the corresponding lateral, longitudinal edge 3 of the rigid part 1 of the hull.
  • the hinge 4 of rubberized canvas has also the funcion of connecting watertight the floating elements 2 to the rigid part 1 of the hull.
  • the central rigid part of the bow and of the stern are connected to the corresponding ends of the floating elements 2 in a pliable and watertight manner, by means of correspondingly shaped walls 5 being also made out of rubberized canvas, or the like and which are glued to the peripheral edges facing eachother of the rigid part of the bow and of the stern and of the floating elements 2.
  • the locking of the floating elements 2 in the active floating position, in which they are overturned outwards the rigid part 1 of the hull, is provided by four kinematic mechanisms, particularly scissors-like mechanisms, which are indicated with the reference number 6 and which are articulated between the ends at the bow and astern of each floating element and the corresponding rigid part of the bow and of the stern of the boat.

  • Levers 13, 14 are articulated in 11 and 12 at the free ends of the arms 7 and 9 and swing around axis which are perpendicular to the axis of oscillation of the arms 7 and 9, the levers 13 and 14 being further linked toghether, swingably around an axis parallel to the axis of oscillation in 11 and 12, at an intermediate point between the two arms 7 and 9.
  • a stop pin 16 is secured to the floating element 2, the said stop pin being substantially parallel to the free branch of the L-shaped arm 7 to which the lever 13 is articulated.
  • the levers are aligned one with respect to the other and the L-shaped arm 7 abutes against the stop pin 16.
  • the kinematic mechanism acts like a strut, locking the floating elements 2 against swinging inwards, into the hull.
  • the relative angular displacement of the levers 13 and 14 cause the swinging of the floating elements 2 inwards into the rigid part 1 of the hull, in their inactive storage or transport position.
  • the suitable arrangement of the pivot points 7, 10, 11, 12, 15, causes the levers 13, 14, to assume a vertical position relatively to the longitudinal axis of the boat in a protractor-like folded condition.
  • the floating elements 2 can be provided with a longitudinal rigid bar 17 which for example is glued to the part of rubberized canvas and which is provided with a substantially vertical extension 18 at its ends at the bow and astern and to which the L-shaped arm 7 of the locking mechanism is articulated.
  • a boat of the above described kind can show the following dimensions: length 2400 mm, width in the active floating position 1500 mm, width in the inactive storage or transport position 800 mm, height in the inactive position: 500 mm.

  • the tubular body 26 can be glued to the internal side of the stiffening element.
  • the rubberized canvas is not joint toghether in a tubular shaped body, but it is glued airtight with its opposite longitudinal edges to the upper and to the lower edges of the stiffening element 25, which forms a section of the peripheral wall of the tubular inflatable airtight body itself.
  • the broadsides 20 of the rigid small boat 1' are shaped complementary to the stiffening element 25 so that, in the active floating position of the floating elements 22, the convex part of the broadsides fits in the concave recess of said stiffening element 25.
