Definitions
- the present invention relates to a foldable boat.
- Foldable boats are known in the art, obtained in other words by the hinge-like joint of a plurality of laminar elements or panels in at least moderately flexible plastic material, cut according to a suitably shaped contour.
- Such boats have the advantage of being extremely light, which is a feature common to all boats in plastic material, and additionally they are also extremely comfortable to transport and store since in their closed or folded condition they occupy an extremely small amount of room, practically that of the group of laminar elements composing the boat which, in folded condition, assume a planar attitude.
- Foldable boats of the kinds known however, occasionally have limitations, due most of all to the fact that they require a remarkable effort for their erection or opening, and in the water they may not have an always satisfactory safety margin for performing some operations while standing still, such as the return of swimmers or frogmen on board, or the hauling up of persons during rescue operations from the stern, since the boats, being very light and not ballasted, may be subject to pitching up, with the risk of swamping water.
- the conventional hinge-like joints between the various panels which compose a foldable boat besides being often too stiff, which entails a considerable effort for unfolding and opening out the boat, are also difficult to provide.
- An aim of the present invention is to provide a foldable boat which is capable of eliminating or substantially reducing the above described disadvantages.
- Another object of the present invention is to provide a foldable boat which may be erected, starting from its folded condition, in a simple and quick manner, and most of all without effort.
- Another object of the present invention is that said boat be endowed with a fully tried stability in water even in case a load has to be hauled on board.
- Not least object of the present invention is that said boat can be provided at competitive costs, to be advantageous also from an economical point of view.

Abstract
Description
- The present invention relates to a foldable boat.
- Foldable boats are known in the art, obtained in other words by the hinge-like joint of a plurality of laminar elements or panels in at least moderately flexible plastic material, cut according to a suitably shaped contour. Such boats have the advantage of being extremely light, which is a feature common to all boats in plastic material, and additionally they are also extremely comfortable to transport and store since in their closed or folded condition they occupy an extremely small amount of room, practically that of the group of laminar elements composing the boat which, in folded condition, assume a planar attitude.
- Foldable boats of the kinds known, however, occasionally have limitations, due most of all to the fact that they require a remarkable effort for their erection or opening, and in the water they may not have an always satisfactory safety margin for performing some operations while standing still, such as the return of swimmers or frogmen on board, or the hauling up of persons during rescue operations from the stern, since the boats, being very light and not ballasted, may be subject to pitching up, with the risk of swamping water. Furthermore, the conventional hinge-like joints between the various panels which compose a foldable boat, besides being often too stiff, which entails a considerable effort for unfolding and opening out the boat, are also difficult to provide.
- From US-A-3482368 is known a foldable and erectable boat according to the first part of the appended Claim 1 and particularly comprising hinge-like joints with only one groove formed on the outer surface of the panels and having reduced flexibility and resistance to repeated bending.
- An aim of the present invention is to provide a foldable boat which is capable of eliminating or substantially reducing the above described disadvantages.
- Another object of the present invention is to provide a foldable boat which may be erected, starting from its folded condition, in a simple and quick manner, and most of all without effort.
- Another object of the present invention is that said boat be endowed with a fully tried stability in water even in case a load has to be hauled on board.
- Not least object of the present invention is that said boat can be provided at competitive costs, to be advantageous also from an economical point of view.
- These and other objects which will better appear hereinafter are achieved, by a foldable and erectable boat, according to the appended Claim 1.
- Further features and advantages of the invention will better appear from the following detailed description of some currently preferred, but not exclusive, embodiments thereof, given by way of non-limitative example only, with reference to the accompanying drawings, where:
- Fig. 1 is a perspective view of a boat according to the invention, in a fully folded condition, in which it appears as a stack of panels connected in a folding manner along the length;
- Fig. 2 is a view of the boat of Fig. 1 in a partial open or erected condition;
- Fig. 3 is a perspective view from the stern of the boat of Fig. 1 in an erected or completely open condition, and equipped with a motor supporting plate with a stabilizer fin;
- Fig. 4 is a lateral perspective view of the boat of Fig. 3 equipped with an outboard motor and with lateral stabilizers;
- Fig. 5 is a perspective view in an enlarged scale of the motor supporting plate seen from inside the boat;
- Fig. 6 is a view, in an enlarged scale with respect to Fig. 3, of a spacer seat seen from below and equipped with foldable resting legs;
- Fig. 7 is a detail view of an internal side of the boat of Fig. 3, where an abutment and supporting bracket is located for an end of a spacer seat such as the one of Fig. 6;
- Fig. 8 is an axonometric view in an enlarged scale of an edge machined with two opposite grooves of a panel for obtaining a boat according to the invention;
- Fig. 9 is a lateral perspective view of another embodiment of a boat according to the invention;
- Fig. 10 is a partial and slightly enlarged perspective view of a transverse intermediate section of another example of boat;
- Fig.11 is a perspective view, slightly from above and from the prow, of the boat of Fig. 10;
- Fig. 12 is a perspective view, slightly from above and from the stern, of the boat of Fig. 10; and
- Fig. 13 is a perspective view of a detail related to a prow point of a boat according to the invention.
- In the various figures of the drawings, identical or similar components have been referenced with the same reference numerals.
- With reference to Figs. 1 to 8, it will be noted that a boat according to the invention is composed of four
panels transverse edge 7 and 8 with a very small length. Each panel is formed of at least moderately flexible material, as an example propylenic plastic material of adequate thickness, and is machined, proximate to the edges, by having it pass through a pair of milling cutters or shaping rollers, so that it is endowed with two opposite grooves, an internal one 9 and an outer one 10, provided on a respective face of each panel (Fig. 8). The presence of thegrooves strip 12 and causes a reduction in the thickness of each panel, which will be slightly weakened, and therefore more flexible, along the grooves. - The
panels adjacent border bands 12, which are thus rendered rigidly coupled to each other according to a reciprocal folding arrangement. Advantageously, on the outside of each joint or seam, atubular body 13 is inserted, longitudinally fissured, which at its longitudinal edges or lips engages theouter groove 10 of each of the two panels joined together to form the joint and covers and simultaneously externally protects the seam composed of thebands 12, now rigidly coupled to each other, of the panels. Along the free edges 5 of thepanels 1 and 4, thetubular body 13 engages in the twogrooves - The
grooves - This allows to erect the boat, as illustrated in Fig.2, by simply pushing apart the edges 5 of the
lateral panels 1 and 4. The erection of the boat, besides originating elastic folds at the root of the joining seams, also causes a notable inward camber of theintermediate panels - Thanks to the non-rigid nature of the material in which the boat is provided, the same is slightly flexible in its entirety, which allows a good absorption and damping of the impact with the waves.
- The boat is held in erected position by one or more seats, generally indicated with the
reference numeral 14 in Figs. 3 and 6. For this purpose, on the inside faces of thelateral panels 1 and 4 of the boat is applied a matching number ofbrackets 15, which in order to follow the weak elastic deformations of the sides of the boat are obtained from a single U-shaped channel with fins divided in three pairs of separate finlets orflaps 16. A pair of flaps, as an example the central one, has a central through hole for fixing the seat in position. - As is shown in Fig. 6, each
seat 14 is formed by a rigid shelf orbeam 17 in wood or plastic material to the lower face of which is hingeably coupled an appendix or restingfoot 18 suitable for abutting against the bottom of the boat at the joints between theintermediate panels foot 18 can be folded or turned over against the beam, since it is articulated with theshelf 17 by means of thehinge 19, so that is can occupy a small space when not in use, and allows for an easier transportation on vehicles. Advantageously, theshelf 17 in its lower face can be endowed withfloatability reserves 20 which help make the boat unsinkable. - At the prow, a
rigid support 21 can be removably positioned, which can comprise ametal plate 23 endowed with twolateral fins outboard facings plate 23 is endowed with twoholes panels fins panel 4. - The
support 21 acts as a coupling plate for anoutboard motor 30 as is shown in Fig. 4, or as a resting base for a rudder. - On the outside of the stern, at the
holes plate 23 can also be fixed a stabilizing fin 31 (in broken lines in Fig. 3) which is intended to prevent an excessive pitching down of the stern and thus allows an optimum cruising attitude when employing motorized propulsion. - At the prow a
point 32 can be provided (Fig. 13) in wood or other light material, which at the point can rest on the free edge created by the convergence zones of the ends 7 of the panels, and on board it is supported by atension element 34 which connects the twolateral panels 1 and 4 of the boat. This point, apart from defining a small shelter for holding objects at the prow, can act as a platform for diving into the water. - Advantageously, on the outer sides of the boat two
floaters 36 can be seen (Fig. 4), which extend from the prow to the stern and have, as an example, a semicircular cross section. Thefloaters 36 can be provided in a very light material or may be inflatable to give the boat a greater lateral stability, represent a notable floatability reserve, make safer the return aboard of a swimmer or a frogman, and ease possible rescue operations. - The coupling of the
floaters 36 can be provided, e.g., by ahook 37 on the prow which, as an example, is anchored to thetension element 34, on the stern by means of thehook 38 fixed to a coupling bolt of themotor plate 21, and two or threeintermediate points 39 for fixing or hooking to the hull, as an example above the seats and/or by providing a hole in the side of the boat. - The boat illustrated in Fig. 9 shows a
stern extension 40 which acts as a rear extension of the underbody of the boat and can be provided in place of thefin 31. Theextension 40 can be an inflatable body or be composed of a very light material, and can be advantageously associatable with the boat, as an example, at and along the stern ridges. Theextension 40 is intended to extend the keel and therefore allows to increase the cruising speed of the boat, other things being equal. - Figs. 10 to 12 show another embodiment of the boat according to the invention in which the
seats 45 are composed of a body, inflatable and configured to rest against the internal walls of the hull, to which it is sealingly fixed in any appropriate manner, and to have an appendix orintermediate extension 46, which acts as a resting leg of the body of the seat against the bottom of the hull. Theseats 45 are endowed with valve means 47 for being inflated by means of a pressurised fluid source, e.g. a bottle of compressed air or a pump. Theseats 45 constitute, in this version of the boat, a means for the automatic erection of the boat, since by inflating the seats the boat, from a folded position, is automatically extended into the erected position for use. They furthermore represent a reserve of floatability such as to make the boat unsinkable. Theseats 45, besides being provideable in numerous sections, can have a configuration which is different from the one illustrated in the drawings. - For folding the boat after use, it is sufficient to deflate the
seats 45 and, thanks to the resiliency of thepanels - Fig. 11 also shows
rowlock holders 48 foroars 49. - A boat according to the present invention can in any case be endowed with a mast and a sail, as well as with lateral stabilizers and rudder, in any suitable way and without difficulty. A boat according to the present invention is very versatile, very light, practical to use and can be stored and transported in a very small amount of room, since it occupies an amount of room even smaller than that of a floating or surf board.
- The dimensions can be any according to the requirements.
