    [0001] The present invention relates to a personal vehicle, also sometimes referred to as a personal carrier. By personal vehicle, we mean a vehicle of small size, intended to make the movements of a single person faster and less tiring.
    [0002] Incidentally, such a personal vehicle can also be used to transport another person. Among the personal vehicles already on sale on the market, there are those belonging to the family of Segway. These gyropodes are so called because they use a gyroscopic stabilization system allowing their user to dynamically control the speed of movement of the vehicle and its direction of travel. For the user, this dynamic control is simply moving his center of gravity forward to move the vehicle forward, backward to slow it down, and to the right or left when he wants to move towards the one of his two directions.
    [0003] Gyropods known and currently available on the market are sold under the brands SEGMAY®, EWEE® and ROBIN-M1®. These three gyropodes comprise two motorized wheels and mounted on either side of a platform on which the user stands, and a column of pipe extending from the platform and providing at its upper end holding handles for the user. According to a drawback, the user's hands are not free when he moves using one of these gyropods. Indeed, to avoid losing balance and risk of falling violently on the ground, the user must necessarily cling to the holding handles of the driving column.
    [0004] At best, when using these gyropods, only the most experienced users can hold with one hand and perform an action or carry an object with the other hand. Also, there are other personal vehicles similar to gyropods, but releasing the hands of the user during a trip. For example, the company TOYOTA® has developed a gyropod under the name WINGLET® also taking the form of a platform with two motorized side wheels and on which the user stands. However, unlike the previous gyropodes, the steering column of the Segway WINGLET® is replaced by two arms extending from the center of the platform and offering at their upper ends two supports for the legs of the user, the two supports approximately at the height of the user's calves. Thus, when using the WINGLET® gyropod, the user must tighten the two supports between his legs to stand in balance on the platform.
    [0005] Although freeing the hands of the user, having to tighten the supports between the legs can tire users, especially on long trips. Finally, in general, and despite the performance of the new gyroscopic stabilization systems, all the side wheel gyropods similar to those just mentioned do not have a foolproof stability vis-à-vis the pitching movements, that is to say rocking movements from front to back or back to front, which may be caused by a user's driving error or by an obstacle on the ground. In addition, when the user carries an object while standing on such gyropods, his driving is disturbed by the weight of the object he carries.
    [0006] In fact, the transported object modifies the center of gravity of the user who must therefore adapt his behavior to the weight of the object he is carrying. At the same time, HONDA® has developed a personal vehicle called UniCub® that behaves like a Segway by moving its center of gravity. However, unlike the previously described vehicles, the Uni-Cub® includes a saddle and side pedals allowing the user to move in a seated position. In addition, instead of two side wheels, the Uni-Cub® comprises a large central wheel whose tread is constituted by a plurality of transverse wheels arranged radially around the axis of rotation of the central wheel, as well as a transverse rear wheel whose axis of rotation is perpendicular to that of the central wheel and parallel to the front-rear direction of the vehicle. If this arrangement of the wheels improves the stability of the vehicle vis-à-vis the pitching movements, it reduces this stability vis-à-vis the roll movements, that is to say rocking movements from left to right and from right to left. Finally, and although more comfortable, the sitting position reduces the view and height of access of the user, which can be embarrassing when moving in the middle of a crowd, or in situations in which l The user must stand up to perform an action with his hands or to catch an object. Also, there are other personal vehicles offering more stability through a four-wheel design and preserving the view and height of access of the user through a mid-seated position mid-stand. Such a vehicle is described in the application US-6,845,829.
    [0007] In order to free the hands of the user, the personal vehicle described in this application US-6,845,829 includes rotary pedals for driving the vehicle in direction and speed with the feet. Specifically, two right and left pedals can control the rotational speed of the axes of two motors independently driving the right and left rear wheels of the vehicle. These two pedals are rotatably mounted on either side of the vehicle chassis and about axes perpendicular to the front-rear direction of the vehicle. To control the vehicle in speed, the user rotates the two pedals together with his feet forward or backward, and to drive it in direction, it turns the two pedals differently from one another so that the two rear wheels have different speeds of rotation, the vehicle moving away from the side of the wheel that rotates the fastest. Although relatively simple theoretically, the steering of the vehicle described in the application US-6,845,829 requires a certain dexterity and does not offer an intuitive driving. Indeed, few people are naturally accustomed to driving a vehicle in direction by operating two pedals or two levers simultaneously but differently.
    [0008] According to another disadvantage, the pedals of the vehicle described in the application US-6,845,829 are located under the vehicle seat and in the vertical axis of this seat, support plates being provided at the front of the chassis of the vehicle. vehicle and at mid-height between the pedals and the seat for the knees of the user. This positioning of the pedals confers a driving position favoring the tilting of the upper body of the user forward, especially during a deceleration of the vehicle. Also, to overcome this drawback, the document US-6,845,829 provides a railing enclosing the size of the user. However, this guardrail is uncomfortable and it prevents the user from getting on and off the vehicle quickly, which can be inconvenient for professional use. The present invention aims to overcome the disadvantages of the prior art. To this end, the invention relates to a personal vehicle drivable with the feet, the vehicle comprising a frame extending in length along a longitudinal axis, in width along a transverse axis, and in height the along a vertical axis, the vehicle further comprising a front wheel set mounted at the front of this frame, a rear wheel set mounted at the rear of this frame, a seat mounted on this frame, at least one motor for driving in rotation at least one wheel of a wheel train, means for supplying the engine, and means for driving the vehicle in speed and direction in the form of two right and left pedals, each pedal comprising a receiving surface of a foot of the user, and at least one pedal, said speed, being rotatably mounted relative to the frame about a tilt axis perpendicular to the vertical axis of the vehicle frame , a rotation of this pedal speed around its tilt axis being used to drive the vehicle in speed. According to the invention, the personal vehicle is characterized in that at least one pedal, said steering, is rotatably mounted relative to the chassis about a pivot axis parallel to the vertical axis of the vehicle chassis, a rotation of this pedal direction about its pivot axis being used to steer the vehicle towards. However, in a preferred embodiment of the personal vehicle control means, the two right and left pedals are steering pedals, these two pedals of right and left direction being rotatably mounted relative to the frame respectively about axes of right and left pivot parallel to the vertical axis of the vehicle frame, and simultaneous rotations of these two left and right steering pedals around their right and left pivoting axes being used to steer the vehicle towards.
    [0009] Therefore, the steering towards the personal vehicle according to the invention is obtained by a yaw movement imposed on the pedal or the steering pedals, this yaw movement consisting of a rotation of a pedal from right to left around a substantially vertical axis. Advantageously, this yaw movement of the pedal or of the pedals gives the vehicle a more natural driving action for the user. In addition, the two pedals being mechanically linked to pivot simultaneously and at the same angle around their respective pivot axes, the drive means in the direction of the personal vehicle according to the invention do not require any particular ability. Therefore, as the personal vehicle according to the invention offers steering in the intuitive direction, it is easily used by the majority of users. Still with a view to facilitating the use of the personal vehicle according to the invention, a rotation of the right pedal about its right tilting axis is used to increase the speed of the vehicle, and a rotation of the left pedal about its axis. left swing is used to reduce the speed of the vehicle.
    [0010] Indeed, these pitching movements of the pedals, that is to say of rotation back and forth about a substantially horizontal axis, are well known to users to control the acceleration and braking of ordinary vehicles such as automobiles. According to another advantageous characteristic of the design of the steering means in the direction and speed of the personal vehicle according to the invention, the two right and left pedals are mounted at the front of the vehicle frame, the seat being in a central position in the length and width of the vehicle chassis. Specifically, the pedals are mounted side-by-side on the vehicle frame, between the two wheels right and left of the front wheels. This positioning of the pedals in front of the seat allows the user to stand in a sit-stand position with the legs forward, this driving position improving the comfort and stability of the user of the vehicle.
    [0011] In addition, this driving position legs forward allowing the user to better withstand the kinetic energy that drives his body forward during each deceleration of the vehicle, it avoids the use of a guardrail belting the user and preventing him from getting on and off the vehicle quickly. Other features and advantages will become apparent from the following description of the invention, a description given by way of example only, with reference to the appended drawings in which: FIG. 1 is a perspective view of the personal vehicle according to the invention with a first variant of its chassis, FIG. 2 is a perspective view of the personal vehicle according to the invention, with a first variant of its chassis, FIG. 3 is a view from below and of details of a first variant. directional means of the personal vehicle according to the invention, with a first variant of its chassis, Figure 4 is a bottom view in perspective of a second variant of the directional means of the personal vehicle according to the invention, with a first variant of its frame, Figure 5 is a perspective view of the personal vehicle according to the invention, with a second variant of its deployed chassis, Figure 6 is a broken view Side view of the personal vehicle according to the invention, with a second variant of its deployed chassis, Figure 7 is a side view of the personal vehicle according to the invention, with a second variant of its folded chassis, Figure 8 is a perspective view of the personal vehicle according to the invention, with a first variant of its chassis, and with its folded seat, Figure 9 is a perspective view of the personal vehicle according to the invention, with different advertising equipment and useful for use touristic.
    [0012] As illustrated in FIGS. 1 and 5, the present invention relates to a personal vehicle 10 drivable with the feet. By driving with the feet, the invention means that the user drives the vehicle 10 in speed and direction only with his feet.
    [0013] Indeed, an essential objective of the present invention is to allow a user to move easily and quickly without having his hands taken by the vehicle control means. As can be seen in FIGS. 1, 2, 5 and 6, this personal vehicle 10 comprises a frame 12 extending in length L12 along a longitudinal axis AL, in width W12 along a transverse axis AT, and in height H12 along a vertical axis AV. The longitudinal axis AL, the transverse axis AT and the vertical axis AV are perpendicular and they form an orthonormal frame. The personal vehicle 10 further comprises a front wheel gear 14 mounted at the front 16 of the frame 12 and a rear wheel gear 18 mounted at the rear 20 of this frame 12. In a preferred embodiment of the invention , the front wheel gear 14 includes two right front wheels RFD and left RFG, and the rear wheel gear 18 includes two rear wheels right RRD and left RRG. This four-wheel design promotes the stability of the vehicle 10, especially when stopping and when taking turns, and the four wheels of the vehicle 10 also allow the crossing of obstacles such as sidewalks or steps. For the comfort of the user, the personal vehicle 10 also comprises a seat 22 mounted on the frame 12. In more detail, this seat 22 is mounted on the frame 12 so as to allow a user to settle in position half-seated driving half-standing on the vehicle 10, as shown in Figure 9. Next, the personal vehicle 10 comprises at least one motor for driving in rotation at least one wheel of a train 14,18 wheels , and power supply means of this motor.
    [0014] In a preferred embodiment of the invention, the hub of each of the two right front wheels RFD and left RFG integrates an electric motor MD, MG powered by an accumulator battery on the vehicle 10. This battery is not visible in the figures but it is preferably attached to an element of the frame 12 of the vehicle, and protected by a cover.
    [0015] Finally, the personal vehicle 10 according to the invention comprises means 24 for driving the vehicle in speed and direction.
    [0016] These control means 24 take the form of two right pedal PD and left PG, each pedal PD, PG comprising a receiving surface SD, SG of a foot of the user. At least one pedal, called speed, is rotatably mounted relative to the frame 12 around a tilting axis substantially perpendicular to the vertical axis AV of the frame 12 of the vehicle 10, a rotation of this speed pedal around its tilt axis being used to drive the vehicle 10 in speed. For example, a tilting of a pedal forward is used to increase the speed and a tilting of this pedal to the rear can reduce the speed of the vehicle. However, in a preferred embodiment of the invention, the two right pedals PD and left PG are speed pedals, these two right speed pedals PD and left PG being rotated TD, TG relative to the chassis 12 respectively around right ABD and left ABG tilting axes substantially perpendicular to the vertical axis AV of the chassis 12 of the vehicle 10, a rotation TD of the right pedal PD around its right tilting axis ABD being used to increase the speed of the vehicle 10, and a rotation TG of the left pedal PG about its left tilt axis ABG being used to reduce the speed of the vehicle 10. Specifically, a tilting of the right pedal PD forward is used to increase the speed of the vehicle. vehicle 10 forward MAV, and a shift of the left pedal PG forward is used to reduce the speed of the vehicle 10 forward 20 MAV. In addition, and when the vehicle 10 is stationary, a reversal of the right pedal PD to the rear is used to increase the speed of the vehicle 10 in reverse MAR. As indicated above, these pitching movements of the pedals PD and PG, that is to say rotation TD and TG back and forth about substantially horizontal axes ABD and ABG 25 are known and used by a large number of users to control the acceleration and braking of more ordinary vehicles such as automobiles. Therefore, the personal vehicle according to the invention is easily drivable in speed. In order to implement the speed control, and in a preferred embodiment of the invention, each of the rear right wheel RRD and left RRG of the rear wheel train 18 is equipped with braking means 26 visible in FIGS. and 6, these braking means 26 taking for example the form of disc brakes.
    [0017] Alternatively, the braking of the vehicle 10 can also be obtained through the electric motors MD, MG of each of the two wheels right front RFD and left RFG. In addition, each pedal PD, PG used to drive the vehicle in speed is equipped with a sensor measuring its rotation TD, TG about its axis ABD swing, ABG, this measurement being used to speed control each motor driving a wheel and / or to control the braking means 26. At the same time, the personal vehicle 10 according to the invention also offers intuitive and natural steering for most potential users. For this purpose, and according to an important feature of the present invention, at least one pedal, said steering, is rotatably mounted relative to the frame 12 about a pivot axis substantially parallel to the vertical axis AV of the chassis of the vehicle, a rotation of this pedal direction about its pivot axis being used to drive the vehicle 10 in the direction. However, in a preferred embodiment of the invention, the two right pedals PD and left PG are steering pedals, these two right steering pedals PD and left PG being rotatably mounted LD, LG relative to the chassis 12 respectively around APD and left APG pivot axes substantially parallel to the vertical axis AV of the frame 12 of the vehicle 10, and rotations LD, LG simultaneous of these two right and left PD directional pedals PG around their pivot axes right APD and left APG being used to drive the vehicle 10 in direction. As indicated above, these yaw movements of the pedals PD and PG, that is to say of rotation LD and LG from right to left about right APD and left APG substantially vertical pivot axes, are more driving actions. natural. Indeed, a user of the vehicle must simply orient the pedals or pedals PD, PG in the direction towards which he wishes to move with the vehicle. Of course, to allow the vehicle to change direction when the user rotates the steering pedals PD, PG, at least one set of wheels 14,18 comprises steering wheels. In a first variant of the directional means 27 of the vehicle 10 according to the invention, and as illustrated in FIGS. 1 to 3 and 5 to 7, the two right front wheels RFD and the left side RFG are steered.
