Definitions

• the present invention relates the technical field of ridable saddle vehicles, such as, for example, motorcycles, and relates, in particular, to a ridable saddle vehicle comprising a windshield.
• a ridable saddle vehicle in particular a motorcycle, or more in particular, a scooter, with a windshield is well known, to shield, at least partially, the driver from wind, rain and atmospheric agents.
• a windshield is fixed to the front shield of the ridable saddle vehicle, in particular, to an upper portion of the front shield.
• Figure 1 shows an axonometric view of an embodiment, given by way of explanation and not by way of limitation, of a ridable saddle vehicle comprising a front portion and a windshield fixed to the front portion of the vehicle;
• Figure 2 shows a front view of the vehicle of Figure 1 ;
• Figure 3 shows a side view in which the vehicle of Figure 1 and a driver of such vehicle are shown;
• Figure 4 shows a perspective view of a part of the vehicle of Figure 1 and of the windshield
• Figure 5 shows a side sectional view of a part of the vehicle of Figure 1 and of the windshield along the axis of prevailing longitudinal extension of the vehicle;
• Figure 6 shows a top view of the vehicle of Figure 1 .
• the term “windshield” is to be intended generally, so as to comprise, for example, a so-called “windscreen fairing”, which is conventionally smaller with respect to a common windshield, and is constructed to withstand air pressure at speeds higher with respect to the speeds for which a common windshield is designed.
• FIG. 1 -6 show an embodiment of a ridable saddle vehicle 1 .
• the vehicle 1 is a motorcycle 1 , and more in particular a scooter 1 .
• the example shown in the Figures shows, in particular, an embodiment of a motorcycle 1 which takes the form, without however introducing any limitation, of a three-wheel motorcycle or tricycle, comprising two front steerable wheels 101 , 102 and one rear wheel 103.
• a traction motor for example, thermal or electric or hybrid, constrained to the supporting structure and operatively connected to at least one of the two wheels 101 , 103;
• the motorcycle 1 comprises a front portion 2 and a windshield 3 fixed to the front portion 2.
• the front portion 2 is a part of the body of the motorcycle 1 and more preferably is a portion of the aforesaid front shield of the motorcycle 1 .
• the front shield is configured to cover at least part of the front side of the motorcycle 1 .
• the windshield 3 comprises an inner face 3A facing the front portion 2 and an opposite outer face 3B, a lower edge 3C, an opposite upper edge 3D and a pair of side edges 3E, 3F joining, respectively, the aforesaid lower and upper edges 3C, 3D.
• the windshield 3 is fixed to the front portion 2 in a removable manner, preferably by means of fixing screws 14 (Figure 4), for example, by means of four fixing screws 14 as in the example. More in particular, the windshield 3 is fixed to the front portion 2 so that the windshield has a fixed predetermined inclination. In other words, the motorcycle 1 does not comprise elements for adjusting the inclination of the windshield 3 in various positions.
• the front portion 2 and the windshield 3 are configured so as to define a duct 4 therebetween for conveying air configured to be passed through an air flow F1 (the air flow F1 is shown by means of the lines in Figure 3 and by means of the arrows in Figure 5) during the motion of the motorcycle 1 .
• the duct 4 comprises, in particular, an inlet port 5 configured to direct the air flow F1 into the duct 4. Furthermore, the duct 4 comprises an outlet port 6 configured to allow the outflow of the air flow F1 from the duct 4 itself.
• the inlet and outlet ports 5, 6 are arranged centrally with respect to the front portion 2 of the motorcycle 1 and to the windshield 3.
• the inlet port 5 is defined at least partially by the aforesaid lower edge 3C of the windshield 3.
• the inlet port 5 and the outlet port 6 comprise, respectively, an inlet section 5A and an outlet section 6A. In particular, the inlet section 5A is greater than the outlet section 6A.
• the lower edge 3C of the windshield 3 is shaped so as to concentrate the air flow F1 towards the inlet section 5A of the duct 4.
• the term“duct”, employed to define the duct 4 is to be intended generally.
• the duct 4 is a channeling adapted to direct a prevailing portion of the air flow F1 which enters through the inlet port 5.
• the duct 4 is not necessarily a completely hermetic duct according to a direction orthogonal to the prevailing direction of the flow F1 . Therefore, a portion of the air flow F1 may, for example, escape laterally from the duct 4 in case spaces are there through which a portion of the air flow F1 may pass.
• the term "section" employed to define a part of the duct 4, and, in particular, the inlet section 5A and the outlet section 6A, indicates a passage area of the duct 4 which is orthogonal to the prevailing direction of the air flow F1 .
• the inlet section 5A is a free section, i.e. a passage area without grids or other elements which may hinder or determine the load losses in the air flow F1 .
• the outlet section 6A is a free section.
• the duct 4 is a converging duct 4.
• the duct 4 converges in a direction, indicated by the arrow V1 in Figure 4, from the inlet port 5 to the outlet port 6.
• the fact of providing a duct 4 having the inlet section 5A greater than the outlet section 6A, and more preferably the fact of making the duct 4 so that it is a converging duct as described above, allows to accelerate the air flow F1 .
• the air flow F1 is capable of deviating an air flow F2 ( Figure 3) which laps the outer face 3B of the windshield 3 so that the flow lines of the flow F2 are more adherent to the windshield 3 at the trailing edge, i.e., the upper edge 3D of the windshield 3.
• the duct 4 is configured so as to convey the air flow F1 outflowing from the outlet section 6A upwards, tangentially, or substantially tangentially, to the inner face 3A of the windshield 3. This advantageously allows a better upwards deviation of the air flow F2 and therefore improves the turbulence reduction effects at the helmet H1 of the driver C1 .
• the front portion 2 of the motorcycle 1 comprises two protruding fixing supports 7, 8 to which the windshield 3 is fixed.
• the duct 4 is defined at the bottom by the front portion 2, at the top by the inner face 3A of the windshield 3 and at the sides by the fixing supports 7, 8.
• the protruding fixing supports 7, 8 are arranged parallel to one another.
• the protruding fixing supports 7, 8 may be arranged so as to diverge in the direction V1 , and more in particular so as to diverge laterally with respect to the direction V1 .
• the protruding fixing supports 7, 8 diverge from one another so as to convey the air flow F1 towards the whole, or substantially the whole, upper edge 3D of the windshield 3. This advantageously allows to more uniformly distribute the air flow F1 outflowing from the outlet port 6 onto the helmet H1 of the driver C1 and therefore to more uniformly distribute the thrust on the helmet H1 itself with consequent positive effects on driving comfort.
• the protruding fixing supports 7, 8 each have a front portion 7B, 8B proximal to the inlet port 5 which is shaped so as to form a channel for directing the air flow F1 .
• the front portion 7B, 8B of each of the protruding fixing supports 7, 8 is placed at a predetermined distance from the inner face 3A of the windshield 3 so as to allow a portion of the air flow F1 to be directed towards a pair of handles 10, 1 1 of the handlebar 9 of the motorcycle 1 .
• a portion of the air flow F1 may be directed between the inner face 3A of the windshield 3 and the front portions 7B, 8B of the protruding fixing supports 7, 8 by deviating an air flow which laps the outer face 3B of the windshield 3 in a direction transversal with respect to the flow F2, so as to reduce the turbulence in the area which affects the hands and forearms of the driver C1 .
• the driving comfort of the motorcycle 1 is further improved.
• the front portion 2 of the motorcycle 1 is a portion of the front shield of the motorcycle 1 and the protruding fixing supports 7, 8 and the front portion 2 are connected to one another in a single piece.
• the protruding fixing supports 7, 8 and the front portion 2 are preferably made in a single piece. This conveniently allows to reduce the side losses of the air flow F1 , maximizing the positive effects on driving comfort of the flow F1 described above.
• the side edges 3E, 3F of the windshield 3 are shaped laterally so as to form at least partially a pair of handguards.
• the Applicant has found that, although such shaping of the side edges 3E, 3F causes a separation of the air flow lapping the outer face 3B of the windshield on the trailing edge corresponding to the aforesaid pair of handguards and an increase in turbulence downstream of such trailing edge, advantageously the increase in turbulence occurs in an area which does not affect the area of the hands and forearms of the driver C1 . Thereby, the driving comfort of the motorcycle 1 is further improved.
• the windshield 3 comprises a pair of longitudinal stiffening folds 12, 13 extending from the lower edge 3C towards the upper edge 3D of the windshield 3. It should be noted that the folds 12, 13 are folds which do not form steps but rather folds which gradually join two portions of the windshield 3 and which have a rounded section.
