The present invention relates to a windscreen for floating vehicles .
The present invention also relates to a floating vehicle comprising said windscreen.
The present invention is within the nautical and/or marine sector, and more specifically is intended for all floating vehicles, for example craft, pleasure boats, motorboats, yachts, sailing boats in general (in particular including: sailing boats of the type with an auxiliary motor; sailing boats of the type known as "motorsailers" , that is to say mainly motor-propelled though equipped with sails) or any boat whose control cabin is located inside the hull structure.
As is known, yachting currently involves various types of craft or boats, having different shapes, dimensions, technical and aesthetic set-ups, as well as different control positions. Therefore, there are craft or motorboats referred to as "open", whose control position is external, located in the upper part of the hull, so that the driver is constantly struck by air while navigating.
However, to protect the driver and passengers in bad weather, "open" craft have one or more covering systems to isolate the control position from the outside. One example of such covering systems involves the use of a curved framework supporting a covering tarpaulin. The covering tarpaulin usually has one or more transparent portions made of plastic material through which the outside environment can be seen. The curved framework and covering tarpaulin are usually set up or removed manually. However, it should be noticed that, given the normal dimensions of motorboats, and therefore of the
frameworks, as well as of the covering tarpaulins, it is quite difficult and complicated for the driver or any passenger to move them.
Moreover, while navigating, the action of water spray against the covering tarpaulin as well as the action of the air striking it, causes the covering tarpaulin and the supporting framework to move constantly. In the long run, the slots used to pull tight the above-mentioned tarpaulins tend to become enlarged, meaning that the covering tarpaulin sags and cannot easily be returned to the original tension conditions.
In addition, due to wear on the covering tarpaulin, the transparent portions inevitably become opaque, significantly compromising visibility for the driver while navigating. Finally, it should be noticed that if the operation to remove the covering tarpaulin is not carried out correctly, one or more folds may be made in the transparent portions which remain in them and further reduce visibility for the driver. There are also motorboats known in the sector as "fly", which have two control positions. A first control position is located outside, on top of the boat hull similarly to the control position of "open" models, whilst the second control position is located inside a cabin made in the hull structure. In this case, the motorboat has a hermetically protected control cabin, and an outside control position which can be covered with a covering tarpaulin if necessary, when it is not in use or in bad weather. However, this solution involves duplication of the devices and instruments needed for navigation, having a significant effect on the overall costs of "fly" motorboats, and on their maintenance costs. It should also be noticed that if there is any precipitation, the covering tarpaulin must be set up to protect the outside control position, presenting the same problems and disadvantages as for "open" type motorboats. There is also a third type of motorboat whose control position is located inside a control cabin delimited in the boat hull structure. '
Obviously, since such cabin cruisers do not have an outside
control position, they do not have the problems relating to setting up the covering tarpaulins or similar protective structures. However, with control positions which are completely closed and isolated from the outside, drivers cannot enjoy the so-called "wind effect", that is to say, the action of the air striking uncovered or outside control positions while navigating.
To overcome this disadvantage, cabin cruisers were made whose control position has suitable roofs and/or lateral parts that can open which reduce the feeling of isolation from the outside environment but without giving the feeling of navigation or "wind effect" typical of open boats.
Finally, it should be noticed that during hot seasons such cabin cruisers need considerable air conditioning in the control cabin, which means that it must be completely isolated from the outside, that is to say, total closure of the roof and lateral parts that can be opened.
Disclosure of the Invention In this situation the present invention has for a technical purpose to overcome the above-mentioned disadvantages relating to floating cabin cruiser vehicles.
Within the scope of said technical purpose an important aim of the invention is to provide a windscreen which allows the control cabin to be put into communication with the outside or allows it to be isolated' according to contingent requirements.
Another important aim of the invention is to propose a floating if" vehicle of the cabin cruiser type whose control position can be struck by air while navigating or can be completely isolated from the outside.
The technical purpose indicated and the aims specified are substantially achieved by a windscreen for floating vehicles and by a floating vehicle equipped with said windscreen according to one or more of the technical solutions in the claims herein. Further characteristics and advantages are more apparent from the detailed description of several preferred, non-limiting embodiments of a mobile windscreen for floating vehicles and a
floating vehicle equipped with said mobile windscreen, in accordance with the present invention.

With reference to the accompanying drawings, the numeral 1 denotes as a whole a windscreen for floating vehicles in accordance with the present invention. As shown in Figures 1 to 8, the windscreen 1 is ready for installation on any floating vehicle 2, for example a craft, a small or large pleasure boat, a motorboat, a yacht, a boat, sailing boats in general (in particular including: sailing boats of the type with an auxiliary motor; sailing boats of the type known as "motorsailers" , that is to say mainly motor-propelled though equipped with sails) or any other floating vehicle whose control position 3 is located inside a control cabin 4 made in the hull 5 structure.
Again with reference to Figures 1 to 8 and 11, the windscreen 1 is mounted on a floating vehicle 2, in particular a motorboat 2, whose hull 5 is only partly visible in the drawings. At the upper part of the hull 5, the motorboat 2 has a control cabin 4 inside which there is the control position 3 used by a driver 6 to steer and drive the motorboat 2 while navigating. The example embodiment shows a motorboat 2 , but as already indicated the invention relates to any floating vehicle, for example: craft, pleasure boats, motorboats, yachts, boats, sailing boats in general (in particular including: sailing boats of the type with an auxiliary motor; sailing boats of the type known as "motorsailers", that is to say mainly motor-propelled though equipped with sails) or any boat whose control cabin is located inside the hull structure. In particular with reference to the windscreen 1, the latter
comprises a first frame 7 (Figures 3, 4 and 7 - 14) which can rigidly engage on the hull 5 by means of one or more known fixing means, at a driving opening 5a (Figures 2, 4, 6 and 8 - 13) delimited in the control cabin 4. Alternatively, the first frame 7 may be built directly into the hull 5 structure or may be made directly at the latter 's driving opening 5a.
The windscreen 1 also comprises at least one structure 8 made of transparent material, preferably glass, operatively engaged with the first frame 7 to hermetically isolate the motorboat 2 control cabin 4 from the outside.
In accordance with a first embodiment of the present invention illustrated in Figures 1 to 4, the transparent structure 8 can move relative to the first frame 7 and, consequently relative to the motorboat 2 hull 5, between a first position, in which the control cabin 4 driving opening 5a is hermetically closed (Figures 1 and 3), and a second position, in which the control cabin 4 driving opening 5a is at least partly disengaged from the transparent structure 8 (Figures 2 and 4) , so that the control cabin 4 is directly in communication with the outside. In other words, when the mobile transparent structure 8 is in the first position (Figures 1 and 3), it completely closes the control cabin 4 driving opening 5a, isolating the cabin from the flow of air F which strikes the motorboat 2 while navigating. In contrast, when the windscreen 1 is in the second position (Figures, 2 and 4) the control cabin 4 is open and its driving opening 5a is partly delimited by an upper edge 8a of the mobile transparent structure 8. In this situation, the flow of air F which strikes the motorboat 2 partly enters the control cabin 4, consequently striking the driver 6.
Advantageously, the mobile transparent structure 8 slidably engages with the first frame 7. Appropriately, the first frame 7 extends substantially along the direction of longitudinal extension of the floating vehicle 2, meaning that the mobile transparent structure 8 can slide on the first frame 7 towards the bow of the floating vehicle 2 or away from it. Again with reference to Figures 1 and 2, the mobile transparent
structure 8 delimits the field of vision C of the driver 6 while navigating. In particular, in the first position (Figure 1) , that is to say, with the transparent structure 8 in the closed position, all light from the outside passes through the transparent material before reaching the driver 6. With the transparent structure in the second position (Figure 2), that is to say, in the open position, the light from the outside reaches the driver 6 partly freely, that is to say without refraction by one or more transparent structure, and partly through the moved mobile transparent structure 8. In this way, the following are defined: a clear field of vision CL, without transparent structures inserted in it; and a non-clear field of vision CNL, delimited by the above-mentioned mobile transparent structure 8 in its second position. Obviously, in the second position (Figure 2), the mobile transparent structure 8 might be made to move completely out of the control cabin 4 driving opening 5a so that the driver 6 has a completely clear field of vision C. Appropriately, the windscreen 1 also comprises a covering portion 80 which can be rigidly connected to the first frame 7, below which the mobile transparent structure 8 (or part of it) is at least partly hidden when it slides between the first and second positions. Said covering portion 80 may be built into the hull 5 of the floating vehicle 2 (as illustrated in the examples in the accompanying drawings) , or it may be an additional structure, to be applied on the hull 5 as a protective guard. In accordance with a second embodiment of the present invention illustrated in Figures 5 to 8, the windscreen 1 also comprises another structure 9 made of transparent material, preferably glass, rigidly engaged with the first frame 7 so that the mobile transparent structure 8 can be operated in such a way that it moves relative to the fixed transparent structure 9 whose upper edge 9a at least partly delimits the control cabin 4 driving opening 5a. Again with reference to the embodiments illustrated in Figures 5 to 8, the mobile transparent structure 8 and the fixed transparent structure 9 lie on different levels, so that, at
least in the second position (Figures 6 and 8), that is to say, in the open position, the transparent structures 8, 9 are at least partly overlapping.
As in the first embodiment, when the mobile transparent structure 8 is in the first position (Figures 5 and 7) the driving opening 5a is completely closed and the control cabin 4 is totally isolated from the outside. In this situation, the flow of air F which strikes the motorboat 2 during navigation strikes the outside of the motorboat 2 control cabin 4 structure. In the second position (Figures 6 and 8), the movement of the mobile transparent structure 8 relative to the fixed transparent structure 9 opens the driving opening 5a, through which the flow of air F which strikes the motorboat 2 during navigation partly enters the control cabin 4, thus striking the driver 6.
The mobile transparent structure 8 preferably at least partly engages with the first frame 7 by means of a second frame 10 (only illustrated in Figures 9, 10 and 12 - 13 for greater clarity) . In this case the second frame 10, which acts as a support for the mobile transparent structure 8, can be moved, together with the latter, relative to the first frame 7 between the first and second positions. The mobile transparent structure 8 is moved relative to the first frame 7 by moving the second frame 10. Advantageously, the second frame 10 slidably engages with, the first frame 7 in such a way that' the mobile transparent structure 8 moves by sliding on the first frame 7. 1 With regard to this, the first frame 7 preferably has at least one guide 11 (Figure 14) for the sliding of the second frame 10 and the mobile transparent structure 8.
The guide 11 may engage with the first frame 7 by means of one or more known connecting elements or it may be built into the structure of the frame 7. Again with reference to Figure 14, two identical guides 11 are illustrated, which can support a corresponding portion of the second frame 10 and/or the mobile transparent structure 8 during sliding between the first and second positions.
Each sliding guide 11 preferably extends substantially along the direction of longitudinal extension of the motorboat 2, so that the second frame 10, which in turn has sliding guides 12, slides on the first frame 7 both towards the motorboat 2 bow and away from it.
More specifically, the sliding guides 11 connected to the first frame 7 each have an inverted substantially "T" -shaped cross- section so as to form a sliding track lla alongside two sliding surfaces lib. Advantageously, the guides 12 mounted on the second frame 10 are shaped to match the guides 11 so that they couple with the latter correctly. In detail, each second frame 10 sliding guide 12 has a recess 12a designed to receive the sliding track lla of the first frame 7 guide 11 and two sliding surfaces 12b designed to slide on the first frame 7 sliding surfaces lib.
Obviously, the guides described above may be substituted with any other type of guide able to guarantee reciprocal sliding between the first frame 7 and the second frame 10. For example, the sliding guides inserted between the frames 7, 10 may be of the type which cannot be pulled apart, having an "X" -shaped cross-section or they may even be made in the structures of the frames 7, 10.
In accordance with a third embodiment of the present invention, illustrated in Figure 9, when the driving opening has considerable dimensions such that it is difficult to produce single-piece transparent structures, the mobile transparent structure 8 may consist of two or more adjacent parts 8b, which are preferably identical. In this case, the parts 8b of the mobile transparent structure 8 are kept together by the second frame 10, which has three uprights 10a, 10b, one central 10a and two lateral 10b, and two crosspieces 10c which are substantially perpendicular to the uprights 10a, 10b.
Like the second frame 10, the first frame 7 also has three uprights 7a, 7b, one central 7a and two lateral 7b plus two crosspieces 7c which are substantially perpendicular to the uprights 7a, 7b. However, the first frame 7 may not have the central upright 7a, instead having only the lateral uprights 7b
and the crosspieces 7c .
As in the first embodiment, the mobile transparent structure 8 consists of two parts 8b and can move between the first position and the second position when the second frame 10 slides relative to the first frame 7 and to the hull 5.
In accordance with a fourth embodiment of the present invention illustrated in Figure 10, the first frame 7 has a fixed transparent structure 9 also consisting of two adjacent parts 9b. Each part 9b of the fixed transparent structure 9 is inserted between the central upright 7a of the first frame and the corresponding lateral upright 7b. In this case the mobile transparent structure 8 is moved in the same way as the mobile transparent structure 8 of the second embodiment is moved, that is to say, passing from a condition in which the mobile transparent structure 8 and the fixed transparent structure 9 are on different levels according to substantially adjacent positions, to a condition in which they are at least partly overlapping . In accordance with a fifth embodiment of the present invention illustrated in Figures 11 and 12, the mobile transparent structure 8 has two parts 8b which can be moved, each independently of the other. In other words, each part 8b of the mobile transparent structure 8 can be moved between the first position, in which a corresponding part of the control cabin 4 driving opening 5a is closed, and a second position in which the respective part of the driving opening 5a is at least partly open. In this situation, the first frame 7 has a structure similar to the first frame 7 of the third embodiment, whilst the second frame 10 is divided into two supporting casings 13, substantially square, and able to move independently of each other.
In accordance with a sixth embodiment of the present invention illustrated in Figure 13, the mobile transparent structure 8 has the same structural configuration as the fifth embodiment. In addition, like the fourth embodiment, the first frame 7 has a corresponding fixed transparent structure 9 consisting of two adjacent parts 9b. Each part 9b of the fixed transparent
structure 9 is inserted between the central upright 7a of the first frame and the corresponding lateral upright 7b. Again in this case, each part 8b of the mobile transparent structure 8 is moved in the same way as the mobile transparent structure 8 of the second embodiment is moved, that is to say, passing from a condition in which the respective part 8b of the mobile transparent structure 8 and the respective part 9b of the fixed transparent structure are on different levels according to substantially adjacent positions, to a condition in which said parts 8b, 9b are at least partly overlapping.
Advantageously, the windscreen 1 also has movement means 14
(only illustrated in Figures 1, 2 and 14 for greater clarity) which are operatively connected to the mobile transparent structure 8 to move the latter between the first and second positions.
The movement means 14 preferably comprise at least one fluid dynamic actuator 15 operatively inserted between the mobile transparent structure 8, or the second frame 10, and the motorboat 2 hull 5. As illustrated in the embodiment in Figure 14, the movement means 14 comprise two fluid dynamic actuators 15 operatively located at the sides of the frames I 1 10.
With reference to the third to the sixth embodiments, the movement means 14 may also be operatively located at the central upright 7a of the first frame 7.
Obviously, ' in the embodiments (fifth and sixth) in which the mobile transparent structure 8 is composed of two independent parts 8b, there must be at least one fluid dynamic actuator 15 for each mobile part 8b. It should also be noticed that any other type of movement system able to move the above-mentioned mobile transparent structure 8 may be used in place of the fluid dynamic actuators 15 illustrated, without thereby departing from the scope of the invention. The windscreen 1 is also equipped with suitable seal devices or elements inserted at least between the first frame 7 and the mobile transparent structure 8 to prevent the unwanted entry of
water into the control cabin when the mobile transparent structure 8 is in the first position. Advantageously, the seal devices or elements are also inserted between the first and the second frames 7, 10 to increase the hermetic seal of the control cabin 4 when the latter is kept in a condition in which it is isolated from the outside. The seal devices or elements may be made using in various ways (known to experts in the field) seal means such as seals, stops, drop stop devices and the like. Seal devices and/or elements, in particular drop stop elements or devices may also be present inside the covering portion 80.
The present invention solves the problems encountered in the prior art and achieves the preset aims.
First, the mobile windscreen disclosed allows the creation inside the control cabin of cabin cruisers of the "wind effect" typical of open boats whose control position is outside.
Moreover, during hot seasons, the system described above for moving the windscreen of cabin cruisers allows significant ventilation of the control cabin, satisfactorily substituting air conditioning of it.
