    [0001] BACKGROUND OF THE INVENTION The subject of the present invention is a vehicle, for example of the scooter type. In particular, it finds an application for the practice of outdoor recreation or for medium or long-distance journeys, particularly in urban areas. Numerous examples of vehicles, such as skateboards or scooters, are known which are suitable for these different applications. To facilitate their use, especially by users, such as children, whose sense of balance is undeveloped, there are for example scooters that include a tray to support a user and having a support plane, a set steering assembly comprising a steering column having a first axis and a front axle having two wheels. In these scooters, the steering column is pivotally mounted relative to the plate about the first axis, the first axis and the support plane forming a first angle. The front axle is pivotally mounted relative to the plate about a second axis. The steering column is arranged so that its pivoting about the first axis causes the front axle to pivot about the second axis. Usually, the first and second axes are merged and substantially perpendicular to the support plane of the plate, so that the use of the scooter is difficult, unintuitive and unstable. Indeed, the user is thus positioned near the steering column, generally near the front end of the plate, then risking falling from the plateau when the trajectory of the scooter is changed abruptly, for example if the one of the wheels comes into contact with a stone or the edge of a sidewalk. Also known from US 6,511,083 is a roller board in which the first axis and the second axis are inclined relative to each other by defining a second angle. Nevertheless, in the skateboard described by this document, the steering assembly is configured so that the first angle can be changed by the user when using the wheelboard, in order to change the layout of the wheelchair. the entire direction and allow the user to vary the position of the center of gravity, for example to achieve acrobatic figures. This possibility of modifying the first angle again makes the use particularly unstable, and therefore unsuitable for users whose sense of balance is poorly developed. OBJECT AND SUMMARY OF THE INVENTION The present invention aims to solve, among others, the shortcomings described above of existing vehicles, by providing a stable vehicle that can be easily and intuitively managed, even by users having a weak sense of balance. This object is achieved by the fact that the invention relates to a vehicle, for example of the scooter type, comprising a plate adapted to support directly or indirectly a user and having a support plane, a steering assembly comprising at least one column of direction having a first axis, the steering column being pivotally mounted relative to the plate about the first axis, the first axis and the support plane forming a first angle. In addition, the vehicle according to the present invention comprises a front axle having at least a first and a second ground contact means, the front axle being pivotally mounted relative to the plate about a second axis, the steering column being arranged so that its pivoting about the first axis causes the front axle to pivot about the second axis. In the vehicle according to the present invention, the first axis and the second axis are inclined relative to each other by defining a second angle, the first angle being fixed during use of the vehicle. Preferably, the second angle is also fixed during use of the vehicle. The vehicle according to the present invention thus benefits from the advantages inherent in the fact that the first and second axes are inclined with respect to each other, without compromising the maintenance of the user on the platform and the ease of operation of the operator. the whole direction. Indeed, if the first and second axes coincide by being inclined relative to a direction substantially perpendicular to the support plane, for example so as to move the center of gravity of the vehicle from the front end of the plate, one contact means tends to take off from the ground when the user rotates the steering column; this detachment then causes the pivoting of the plate in the opposite direction to the direction taken by the vehicle, destabilizing the user and risking its fall.
    [0002] In addition, the adjustment of the first angle, chosen so that it is adapted to the user of the vehicle according to the present invention, is not likely to be accidentally modified during the use of the vehicle, such a risky change to disturb the user or even to cause his fall.
    [0003] Finally, the presence of the first and second contact means promotes the stability of the vehicle. The invention is described below in a series of alternative embodiments, which may be considered alone or in combination with one or more of the previous ones.
    [0004] Preferably, the vehicle further comprises a deflection device configured to assemble the steering assembly and the nose gear. Advantageously, the angle transmission device comprises: a first element mounted on the steering column, a second element mounted on the front axle, and a third element mounted on the first element and on the second element. Advantageously, the third element is disposed between the first element and the second element. Preferably, the first axis and the second axis intersect at the angle deflection device. By this arrangement, and by the structure of the angular deflection device, the operation of the vehicle is further simplified, and the rotational drive of the nose gear around the second axis by the rotation about the first axis of the steering column is improved. In addition, the reliability of the operation of the vehicle, and more particularly of its change of direction, is also improved. Advantageously, the angle return device comprises a cardan. Thus, the complexity and the cost of manufacturing the vehicle according to the present invention are reduced, and the reliability of its operation is improved.
    [0005] Advantageously, the first angle is acute. Preferably, the first angle is greater than 45 °, preferably greater than 600. By this arrangement, when the steering column is mounted near the front end of the plate, the inclination of the steering column relative to a direction substantially perpendicular to the support plane allows to move the user away from the front end of the tray. As a result, the center of gravity is also distant from the front end of the plate, so as to further improve the stability of the assembly of the vehicle and its user, when using the vehicle. Advantageously, the second axis is inclined relative to the support plane of the plate. Advantageously, the second axis and the support plane form a third angle, the third angle being straight.
    [0006] In other words, the second axis extends in a direction substantially perpendicular to the support plane. In this arrangement, the first and second contact means remain in contact with the ground when the front axle pivots about the second axis. The stability of the vehicle is thus the same as for the scooters of the prior art. Alternatively, the second axis and the support plane form a third angle, the third angle being obtuse. Advantageously, the third angle is greater than 950, preferably greater than 1000.
    [0007] By this arrangement, the contact means farthest from the center of rotation of the vehicle tends to sink into the ground during pivoting of the steering column about the second axis, while the contact means closest to the center of the Vehicle rotation tends to come off the ground. In response to the behavior of the front axle, the plate on which the nose gear is mounted inclines around the longitudinal axis of the vehicle in the same direction as the direction taken by the vehicle. Thus, the vehicle tray according to the present invention tilts in the same direction as the direction taken by the vehicle; the stability of the user disposed on the vehicle bed is thus improved.
    [0008] By center of rotation of the vehicle is meant the center of the circle whose trajectory of the vehicle draws an arc when the user pivots the steering column about the first axis. By longitudinal axis of the vehicle is meant the longitudinal axis of its tray. Advantageously, the third angle is also fixed during use of the vehicle. By this arrangement, the behavior of the front axle and, consequently, that of the plate, is not likely to be modified accidentally during the use of the vehicle. Preferably, the first ground contact means comprises a first wheel rotatably mounted about an associated axis of rotation. Advantageously, the second means of contact with the ground comprises a second wheel rotatably mounted about an associated axis of rotation. Thus, the movement of the vehicle is facilitated, and its manufacture and maintenance are simplified. Advantageously, the axes of rotation of the first wheel and the second wheel coincide.
    [0009] Alternatively, the first wheel forms a first non-zero camber. Preferably, the first camber is negative. By camber means, considered in a front view of the vehicle, the angle formed by the rolling surface of the first wheel with a direction substantially perpendicular to the support plane of the plate. Thus, when the first camber is negative, the top of the first wheel is inclined towards the vehicle. By this arrangement, among others, the maintenance of the first wheel on the ground during the movement of the vehicle is improved.
    [0010] Advantageously, the second wheel forms a second non-zero camber. Advantageously, the second camber is identical to the first camber. By this arrangement, the behavior of the vehicle is identical, regardless of the direction in which the steering column is rotated about the first axis.
    [0011] Preferably, the nose gear comprises a longitudinal axis, the vehicle further comprising biasing means configured to arrange the longitudinal axis of the nose gear substantially parallel to the support plane of the plate, when the steering column is pivoted about the first axis. By the presence of the return means, the inclination of the longitudinal axis of the front axle relative to the support plane of the plate, when the front axle is pivoted about the second axis, is limited, so as to reduce the risks of destabilization of the user.
    [0012] In other words, the presence of the return means makes it possible to harden the direction of the vehicle, so as, for example, to limit the effects that could have a sudden pivoting of the steering column by the user.
    [0013] BRIEF DESCRIPTION OF THE DRAWINGS Other features and advantages of the invention will appear more clearly and completely on reading the following description of a preferred embodiment given by way of non-limiting example and with reference to following accompanying drawings in which: - Figure 1 shows schematically an example of a vehicle according to the present invention; - Figure 2 schematically shows a side view of the vehicle of Figure 1; FIG. 3 schematically represents an exploded view of the angle-of-view device of a vehicle according to the present invention; - Figure 4 shows a rear view of the vehicle of Figure 1, when the steering column is rotated about the first axis; and FIG. 5 represents a front view of the vehicle of FIG. 1. DETAILED DESCRIPTION OF THE INVENTION In the example represented in FIG. 1, the vehicle 10, in this case a scooter, comprises firstly a tray 12 comprising a support plane 14, the tray 12 being configured to support, directly or indirectly, a user; the support plane 14 comprises a longitudinal direction D which defines a front end 13 and a rear end 15. By extension, in the following description, the front ends 13 and rear 15 of the support plane 14 will be assimilated to the front ends and rear of the vehicle 10 according to the present invention. The vehicle 10 further comprises a steering assembly 16 comprising a steering column 18 having a first axis X1; the steering assembly 16 further comprises a control means 20, 10 in this case a handlebar mounted at the upper end of the steering column 18. By the upper end of the steering column 18 is meant the end opposite to that by which the steering column 18 is secured to the plate 12. The vehicle 10 also comprises a front gear 22, mounted at the front end 13 of the vehicle 10; the front axle comprises, for example and without limitation, a first 24 and a second 24 'contact means, configured to ensure the contact of the vehicle 10 with the ground. For example and without limitation, the first and second contact means 24, 24 'respectively comprise a first and a second wheel 25, 25'. The nose gear 22 also has a longitudinal axis L and a front axle 26, at the longitudinal ends of which are mounted the first and second 25, 25 'wheels. In addition, the vehicle 10 according to the present invention comprises a rear axle 30, mounted at the rear end 15 of the vehicle 10; the rear axle 30 comprises, for example and without limitation, a single contact means 32, for example a wheel. As appears in particular in Figures 1 and 2, the steering column 18 is pivotally mounted relative to the plate 12 about the first axis X1. For example and without limitation, the plate 12 comprises an upper sleeve 17, configured to pivotally guide the steering column 18 about the axis X1. As shown in FIG. 2, the first axis X1 and the plane support 14 form a first angle al. ; by first angle al., denotes the angle formed between the first axis X1 and the longitudinal direction D of the support plane 14. The vehicle 10, in particular by the presence of the upper sleeve 17, is configured so that the first angle ai is fixed; it would be conceivable, and without departing from the scope of the present invention, the presence of adjustment means on the vehicle 10, configured to allow the value of the first angle α1 to be modified, for example as a function of the user of the vehicle 10, prior to the use of the vehicle 10.
    [0014] The nose gear 22 is pivotally mounted relative to the plate 12 about a second axis X2; for example and in a nonlimiting manner, the plate 12 comprises a lower sleeve 19 configured to guide pivotally about the second axis X2 the front axle 26 of the front axle 22. As a result, it is understood that the plate 12, the set of direction 16 and the front axle 22 of the vehicle 10 according to the present invention are secured to each other, so that they can be pivoted together about the longitudinal direction D of the support plane 14. As shown in Figure 2, the first axis X1 and the second axis X2 are inclined with respect to each other by defining a second angle a2. Moreover, the second axis X2 and the support plane 14 form a third angle a3; by third angle a3, the angle formed between the second axis X2 and the longitudinal direction D of the support plane 14 is designated, in a manner similar to the first angle a1. For example and in a nonlimiting manner, the vehicle 10 is configured so that the third angle a3 is fixed; without departing from the scope of the present invention, provision may also be made for the presence of adjustment means configured to modify the value of the third angle a3, prior to the use of the vehicle 10. It is understood that, in the event that the first ai and third a3 angles are fixed, the second angle a2 formed between the first X1 and second X2 axis is also fixed. As will be seen in more detail in FIG. 3, the vehicle 10 according to the present invention includes an angular gear 40 configured to assemble the steering assembly 16 and the nose gear 22; for example and without limitation, the angle of return device 40 of the vehicle 10 according to the present invention comprises a cardan 41. As it appears in the different figures, in particular in Figure 2, the first axis X1 and the second axis X2 intersect at the level of the deflection device 40. For example and without limitation, the angle deflector device 40 comprises a first element 42 mounted on the steering column 18, a second element 44 mounted on the front gear 22, and a third member 46 mounted on the first member 42 and the second member 44, more particularly between the first 42 and second 44 elements. In particular, the angular return device 40 comprises a first axis C1 comprising, for example and without limitation, two pins, the third element 46 being mounted to the first element 42 by the first axis C1. 3, the angular deflection device 40 also comprises a second axis C2 comprising, for example and without limitation, a screw and a nut, the third element 46 being fixed to the second element 44 by the second C2 axis. For example and in a nonlimiting manner, the first element 42 comprises removable fixing means configured to allow the steering column 18 to be dismounted from the first element 42, for example to facilitate the storage of the vehicle 10 according to the present invention, when it is not used. It will therefore be understood that when the steering column 18 pivots about the first axis X1, it also causes the first element 42 of the deflection device 40 to pivot about the first axis X1; consequently, because of the joining of the first 42 and third 46 elements, the third element 46 is rotated. The third member 46 then drives the second member 44 in rotation about the second axis X2. The nose gear 22, on which the second element 44 is mounted, is then rotated about the second axis X2. In other words, it will be understood that the angular deflector 40 is configured such that the pivoting of the steering column 18 about the first axis X1 causes the front axle 22 to pivot about the second axis X2. In other words, the angular deflection device 40 is configured to transmit the pivoting of the steering column 18 to the front axle 22. As shown in particular in FIG. 2, the first axis X1 is inclined with respect to the support plane 14 of the plate 12. More particularly, the first axis X1 is inclined relative to a substantially perpendicular direction relative to the support plane 14. Thus, for example and without limitation, the first angle al., Formed between the first axis X1 and the support plane 14, is acute. The inclination of the first axis X1 with respect to a direction substantially perpendicular to the support plane 14 thus makes it possible to move the control means 20 away from the front end 13 of the vehicle 10; as a result, the center of gravity of the vehicle 10 is also remote from the front end 13, to improve the stability of the assembly consisting of the vehicle 10 and its user. Moreover, and as is clear from FIG. 2, for example and without limitation, the vehicle 10 is configured so that the third angle a3 is obtuse; in other words, the second axis X2 is inclined with respect to a direction substantially perpendicular to the support plane 14 of the plate 12. For example and in a nonlimiting manner, the second axis X2 is inclined in the opposite direction to the plate 12 of the 10. By this arrangement, the pivoting of the front axle 22 around the second axis X2 tends to incline the longitudinal axis L of the front axle 22 with respect to the support plane 14 of the plate 12. FIG. vehicle 10 when the steering column 18 is pivoted about the first axis X1, by actuating the control means 20. In the example shown in this figure, the pivoting of the steering column 18 about the first axis X1 can be done turn the vehicle 10 to the left, so that it describes a circle-shaped trajectory, the center of rotation R of the vehicle 10, defined as being the center of the circle whose trajectory of the vee 10 draws an arc, being then disposed to the left of the vehicle 10. In this embodiment, in which the third angle a3 is obtuse, the pivoting of the steering column 18 about the first axis X1 causes the inclination of the longitudinal axis L of the front axle 22; the contact means 24 'closest to the center of rotation R of the vehicle 10 then tends to detach from the ground, while the contact means 24 farthest from the center of rotation R tends, for its part, to sink in the ground In response, and because of the attachment of the plate 12 with the front axle 22, the plate 12, which, for the sake of clarity, is shown in dashed lines in Figure 4, then tends to tilt around its longitudinal axis D towards the center of rotation R. It is therefore understood that, because of the inclination of the second axis X2, the pivoting of the steering column 18 about the first axis X1 causes the tilting of the plate 12 towards the center of rotation R; the user, who stands on the support plane 14 of the plate 12, is not then destabilized by such inclination of the plate 12. For example and in a nonlimiting manner, the vehicle 10 may comprise configured return means 50 for arranging the longitudinal axis L of the front axle 22 substantially parallel to the support plane 14 of the plate 12, when the steering column 18 is pivoted about the first axis X1, in one or other of the permitted senses. Such return means 50 thus make it possible, among other things, to harden the direction of the vehicle 10, so as to limit the effects that a sudden pivoting of the steering column 18 could have on the trajectory of the vehicle 10. As shown in FIG. the different figures, the first 25 and second 25 'wheels of the first 24 and second 24' contact means 30 of the vehicle 10 are rotatably mounted respectively about their associated rotational axes Y, Y '. For example and without limitation, as shown in Figure 5, in which the plate 12 has also been shown in dotted lines for the sake of clarity, the axes of rotation Y, Y 'are inclined with respect to the axis longitudinal L of the front axle 22.
    [0015] Thus, the first 25 and the second 25 'wheels respectively form a first C and a second C' non-zero camber. By first and second cams C, C 'is meant the angle formed by the rolling surface, respectively, of the first 25 and the second 25' wheels, with a direction substantially perpendicular to the support plane 14 of the plate 12 This inclination of the first and second wheels 25, 25 'makes it possible, inter alia, to improve the adhesion of the vehicle 10 according to the present invention.
    [0016] The above description is given by way of example, and is therefore not limiting of the invention; in particular, the invention, although particularly adapted to the field of scooters, can also equip any means of displacement, such as a skateboard or a scooter with two front wheels, so as to facilitate the steering of the vehicle, 15 without compromise stability. 20
