Description

 The invention relates to a vehicle powered by a pedal system.

 The subject of the invention relates in particular to the technical sector of vehicles and means of transport, to toys, to sports equipment.

 Different vehicles or means of locomotion are known that are simple for getting around, but which require certain sporting skills. Mention may be made, for example, of skateboards, roller skates and other derivative or similar vehicles. These vehicles require users to have a sense of balance and other qualities that greatly limit the number of those who can use them. On the other hand, there are no steering means in these vehicles which make it possible to precisely control the movements. The user does not have a seat helping him to keep his balance.

 Given these objections, the vehicle powered on a pedal system, according to the invention was designed to meet the following main objectives - the vehicle must be able to be used by a large number of people, and be stable, - the risks of loss of balance must be reduced to a minimum, - the vehicle must include a human-powered displacement system which does not require one to rest on the ground, either for travel or when stationary, - give the user is in control of the vehicle at all times and in all circumstances, by offering him the possibility of moving forward, of steering and of stopping, - simple and economical manufacturing, reduced bulk.

 To this end, the means of transport is remarkable in that it comprises a chassis mounted in a stable manner on at least three wheels including two drive wheels mounted in parallel on the same axial alignment and a front steering wheel mounted orientable by relative to the chassis with steering means, the two parallel wheels being driven in rotation by a double system of opposite cranks, each pair of cranks being secured to an axis rotating in a bearing of the chassis, the corresponding cranks being located 'The same side of the systems, each carry at their free ends, a member or support part secured to a footrest plate; on each side of the two systems, said footrest plates, integral with the members or support parts, having a freedom of angular movement relative to said members or support parts.

 Other characteristics will emerge from the following description.

 Figure 13 is a perspective view of an alternative embodiment.

 In order to make the object of the invention more concrete, it is now described in a nonlimiting manner with reference to the exemplary embodiments of the figures of the drawings.

 We see Figures 1 and 2 in particular that the vehicle comprises in a known manner, a chassis (C) shown in a stable manner on at least three wheels (1, 2 and 3).

 The wheels (1 and 2) are mounted in parallel on the same axial alignment and are driven. The wheel (3) is arranged at the front of the vehicle and is steerable by being mounted orientable relative to the chassis with steering means (4).

 According to the invention, the two parallel wheels (1 and 2) are rotated by a double system of opposite cranks (5 - 6) and (.7 -8). Each pair of cranks (5 - 6) and (7 - 8) is integral with an axis (9 and 10) mounted to rotate in two bearings (P) of the chassis (C) (Figure 4).

 The corresponding cranks (5 - 7) and (6 - 8) being on the same side of the systems, each carrying at their free end, directly or in an attached manner, a member or support part (11) integral a footrest plate (12 - 13).

 Each plate (12 and 13) has a freedom of angular movement relative to the support members (11). It is emphasized that the support members can be formed directly by the cranks (5 - 7) and (6 - 8) or else be in the form of an axis mounted fixedly at the end of the free end of said cranks.

 It therefore follows that the foot plates (12 and 13) retain a horizontal positioning during the rotation of the crank systems (5 - 7) (6 - 8), said plates describing an elliptical movement.

 this movement is transmitted to the two rear wheels (1 and 2) by an appropriate transmission system.

 In the example of Figures 1, 3 and 4, the transmission is effected by means of a pedal (14), a chain (15) and at least one pinion (16). The bottom bracket (14) is integral with the axis (9) in combination with the crank system (5 - 6) located at the front. The chain (15) connects the crankset (14) to the pinion (16), integral with the transmission shaft (17) supporting at the end, freely rotating, the rear wheels (1 and 2). This shaft (17) is mounted rotating in a bearing (P1) and axially integral with the rear part of the chassis (C) and more particularly with a median longitudinal element (C1) of said chassis receiving the bearings (p) for the rotation of the crank systems (5 - 6) and (7 - 8).

 The rear axle (17) is coupled to the longitudinal element (C1) of the chassis in the form of a tube in particular, by means of a device acting as a torsion bar in order to have better stability and better efficiency. of use. For example, the rear axle (17) is integral in its middle part, with a coupling sleeve (18) which has a circular centering surface (18a) capable of being engaged with free pivoting at the end of the tubular element. (C1) of the chassis (Figures 5 and 8). The coupling can be carried out by means of a torsion spring (19) fixed both on the sleeve (18) and at the end of the element (C1) (Figure 5). Or, as shown in FIG. 8, the coupling can be carried out by means of an elastomer block (20) fixed as indicated above.

 In a preferred form of realsiation, the section of the bearing (P1) is capped by a stirrup (28) whose branches (28a) are directed in the direction of the bottom. Each of the branches (28a) is pierced on the side; in part to allow free engagement of the rear part of the tubular element (C1) of the chassis (Figure 12) below the bearing (pi). A flange (29) and a pin (30) for example, ensure the locking in translation of the stirrup, and consequently of the shaft (17) having regard to the tubular element (C1) of the chassis. A torsion spring (31) is mounted at the end of the element (C1) while being positioned between the arms (28a) of the stirrup (28).

 It therefore follows that the rear axle (17) can be subjected to torsional stress with respect to the carrying frame (C).

 As indicated above and shown in FIGS. 9, 10 and 11, the median tubular element (C1) of the chassis is positioned under the motor shaft (17) which has the effect of lowering the center of gravity of the vehicle, further improving stability. In this case, preferably, the bearings (p) for the rotation of the crank systems (5 - 6) and (7 - 8) are fixed on the top of the tubular element (C1).

 The pinion (16) can advantageously, in a known manner, be equipped with a freewheel Similarly, the drive shaft (17) can be equipped with several pinions and receive a gear change.

 The steering element (4) is in the conventional form of a handlebar, the branches (a) of which are bent in the upward direction to allow abnormal use of the vehicle in the standing position of the user. This handlebar is capable of being foldable to facilitate transport and storage of the vehicle.

 The head tube (4) is, at the base, integral with a diagonal tube (cula) formed directly at the end of the front part of the middle element (cry) of the chassis, while a curved tube (C5) connects the top of the steering tube (4) and the rear part of said element (C1) (Figures 9 and 10).

 In the embodiment shown in Figures 2, 6 and 7, the rotational movement of the two crank systems is directly transmitted to the rear wheels (1 and 2). For this purpose, the support members (11) of the foot plates (12 and 13) located at the rear of the latter, extend beyond the length of said plates to be fixedly coupled in the thickness of the flanges (la and 2a) wheels (1 and 2) (Figure 7). The wheels (1 and 2) are mounted free to rotate inside a curved peripheral profile (21) acting as a bumper by connecting the two ends of the median longitudinal element (C1) of the chassis.

Vehicle operation is the same as before
Whatever the embodiment, the foot plates (12 and 13) are equipped in their front part, with a strap or flange (22) acting as a toe clip and facilitating the particular pedaling movement according to the invention. The lengths of the cranks (5 - 6) and (7 - 8) of each of the systems are equal so that the plates (12 and 13) always remain in a horizontal position. Optionally, the lengths of the cranks (5 - 6) of the same system can be different from the lengths of the cranks (7 - 8) of the other system so that the plates (12 and 13) occupy an inclined position in one direction and in the other to change the pedaling effect.

 The vehicle according to the invention can be fitted with a plastic or other fairing integrating for example the main constituent elements of the chassis with the drive means (chain, bearing, pinion, wheel shaft, etc.). Similarly, the vehicle may have all types of accessories generally fitted to cycles such as brakes, lighting, gear change, mudguard.

 There is also provision, in an alternative embodiment, as shown in FIG. 13, to equip the chassis not with wheels, but with elements (C2 and C3) of support on the ground acting as perfectly stable legs. . As for the vehicle, the central element (C4) of the chassis receives a double system of opposite cranks (22 - 23) and (24 - 25) coupled two by two on the same side to a footrest plate (26 and 27). An adjustable retarder, frictio or other, is mounted on one of the axes of rotation of the cranks. The use of this device is done in the end position, which has the effect of promoting bodybuilding of the legs while developing the notions of balance.

 It is obvious that the vehicle or the device according to the invention can be executed in any size and material.

 Provision is made, as shown by the dashed line in FIG. 9, to equip part of the chassis (C) of the vehicle with a stand (32), the free end of which is arranged directly or in an attached manner with means ( 33) acting as a seat, and more particularly as a support for the posterior support of the user. This stand (32) can be adjustable in height and shaped at its base to be folded down on the chassis during transport of the vehicle.

 The advantages are apparent from the description. We underline and we call back - Can be used in all circumstances, without special attire and for short and medium distance trips, in town or in the countryside, as well as in public places such as stations, airports, ... .

- Ideal use to maintain good physical condition.

- The small size, a cover bag can allow the transport of the vehicle under the arm.

- The user is always in an upright position even if he is driving across a slope.

 The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts which have been more particularly indicated; on the contrary, it embraces all its variants.
