    FRONT TRICYCLE OR TRIPORATOR TRAIN FIELD OF THE INVENTION
    The present invention relates to the field of pedal cycles. It relates in particular to a front train to transform a conventional cycle tricycle or scooter.
    BACKGROUND OF THE INVENTION
    Today, with the increase in urban pollution, many individuals have made the choice or plan to use their bicycle more widely for their different urban or suburban journeys: to go to work, to make business trips, for example of delivery, moving inside an extensive industrial site, taking children to school, going shopping, hiking ... Despite many solutions consisting of small trailers to attach to the back Bicycles, baskets to attach to the handlebars or luggage racks, conventional bicycles are not sufficiently practical, safe and manageable vehicles for the transport of children or goods, to effectively replace the car in everyday life.
    To gain stability, several three-wheeled vehicles (tricycles or scooters) have appeared. However, they have the disadvantage of being less suitable for leisure such as hiking, compared to bicycles, forcing the user to own a bicycle and a tricycle to meet all its needs.
    An elegant solution is therefore to provide a system capable of transforming a conventional bicycle into an urban trike or tricycle, in a simple and fast manner.
    Document US20140091551 proposes a system for making bicycles more utilitarian and functional. The apparatus includes a frame member attached to the bottom portion (crankcase housing) of the existing bicycle, and a member attached to the fork in place of the original front wheel. The device is steerable using handlebars and fork and is configured for cornering stability. The aircraft includes a cargo transporter located at the front of the tricycle, allowing the load to be seen, while maintaining a stable center of gravity and also an ability to lean for cornering stability. A disadvantage of this solution comes from the fact that the assembly remains complex, so inflexible in the case of multiple use in bicycle or tricycle.
    EPI 690782 discloses a trailer coupling to a bicycle. Said trailer includes a first frame part, a frame coupler disposed on the first part and by means of which the first part of the frame can be rigidly coupled to the frame of the bicycle, a first wheel and a second wheel arranged parallel to one another. at the other, and which can be directed about a steering axis to guide the path, and a steering mechanism connected to the wheels, so that the path can be adjusted by means of the steering mechanism. The steering mechanism includes a steering support adapted to be coupled to the free end of the front fork when the front wheel of the bicycle is removed. The steering axes of the first wheel and the second wheel are moved in the longitudinal direction of the bicycle trailer with respect to the steering axis of the bicycle when the trailer is coupled to the bicycle. This solution provides a very good stability but has a lack of maneuverability of the handlebar for the user, given the lack of inclination of the front wheels relative to the ground. In addition, it is not adaptable on all conventional bicycles.
    EP2077223 relates to an improved fork for bicycles or the like, intended for the transport of objects, which consists of: an upper fork, which is fixed at its lower part to a trapezium body, two blocks placed on each side of this body and articulated on the trapezium, each block being equipped with at least one wheel and an independent damping system - fasteners for fixing at least one platform for transporting objects. 1 / main disadvantage of this solution comes from the fact that the platform for the transport of object is fixed on the fork: a large load will thus tend to impact the handling of the handlebars and will be uncomfortable for the user.
    OBJECT OF THE INVENTION
    An object of the invention is therefore to provide a device overcoming the disadvantages of the prior art. An object of the invention is notably a front pedal cycle train, making it possible to transform a conventional bicycle into a tricycle or tricycle that is easy to handle, safe and offers driving comfort close to that of a bicycle.
    BRIEF DESCRIPTION OF THE INVENTION The invention relates to a front train of a pedal cycle comprising two tilting front wheels associated with a deformable parallelogram mechanism, comprising at least two substantially horizontal rigid bodies in rotating connection with a substantially vertical central rigid body. and with two rigid lateral bodies, substantially vertical and respectively linked to the wheels; the front axle being remarkable in that: • At least one of the substantially horizontal rigid bodies comprises fastening means for securing a transport module of a load; • A damping spring system with dry friction is secured to the central rigid body and supported at its ends by holding guides disposed on one of the substantially horizontal rigid bodies.
    According to advantageous features of the invention, taken alone or in combination: • the central rigid body is integral with a steering fork of said pedal cycle; At least two attachment zones make the rigid central body and the steering fork integral; • Fixation zones on the rigid central body are adjustable in height to fit different sizes of fork or bicycle; The central rigid body constitutes a steering fork of said pedal cycle; • the fastening means for securing the module are on the substantially horizontal upper rigid body of the deformable parallelogram mechanism and the upper rigid body has a width greater than that of the lower rigid body; The front axle of a pedal cycle further comprises a module adapted to the transport of the load, only integral with one of the substantially horizontal rigid bodies; • the module is a platform or a trolley or box for transporting children; • the longitudinal position of the retaining guides on the rigid body is adjustable to allow adjusting the damping effects and spring; • The dry friction damping spring system is a blade damping system; • the number or thickness of the blades making up the shock absorber system can be modified to adjust the damping and springing effects.
    The front axle of a pedal cycle according to the invention makes it possible to limit the impact of the weight of the load on the steering fork, the load transport module being intended to be secured to one of the horizontal rigid bodies and not directly on the steering fork of the pedal cycle.
    In addition, the front axle according to the invention makes it possible to dampen the tilt movements of the steering fork and to help it return to its central position, thanks to its adjustable dry-friction damping spring system.
    The front axle according to the invention makes it possible to transform a bicycle into a trike or tricycle easily, by fixing itself in two fixing zones on the fork, after removal of the front wheel of the bicycle.
    It can also form the front train of a nontransformable trike or tricycle, the central rigid body can be adapted to form the steering fork of the cycle.

    DETAILED DESCRIPTION OF THE INVENTION
    Figure 1 shows a first embodiment of a front train 1 of a pedal cycle according to the invention. In the remainder of the description, we will consider that the front train 1 is in a rest position identical to that which it would have after fixing on a bicycle, and this for the sake of simplification of its description in space. The terms upper, lower, front, back, front, back, ... will have to be interpreted in this context.
    The front axle 1 comprises two wheels 2,3 linked to a deformable parallelogram mechanism. The wheels may have for example a diameter of between 30 and 60 cm, preferably 45 cm. They may be equipped with a braking system (not shown) on each of them, which may be selected from disc or pad brake systems. The braking is evenly distributed on both wheels by a system of cables and rudder or hydraulic braking.
    The nose gear 1 further includes the deformable parallelogram mechanism; it comprises two rigid longitudinal bodies 4,5 which are substantially horizontal in the operating position (at rest), that is to say when the front axle is mounted on a pedal cycle. The rigid body 4 constitutes the upper rigid body and the rigid body 5 constitutes the lower rigid body. The deformable parallelogram mechanism further comprises three rigid transverse bodies: a central rigid body 6 and two rigid lateral bodies 7,8, which are substantially vertical in the operating position (at rest). The two substantially horizontal longitudinal rigid bodies 4,5 are articulated in a rotating connection with the three substantially vertical transverse rigid bodies. The rotating connection is for example provided by pivot elements or ball joints of the type of guide bearings or ball bearings. This connection allows the parallelogram mechanism to deform by allowing translational movement between the two longitudinal rigid bodies 4,5, concomitant with an inclination of the three rigid transverse bodies 6,7,8. The two wheels 2,3 are respectively connected to the two rigid lateral bodies 7,8 by an axis (along the x axis) allowing them a rotational movement. During the inclination of the rigid lateral bodies 7,8, the wheels 2,3 follow the inclination movement: they therefore have the characteristic of being reclining. Alternatively, each wheel may be provided with a fender (not shown) attached to each lateral rigid body 7,8.
    At least one of the longitudinal rigid bodies 4,5 comprises fixing means for securing a transport module of a load. According to the first embodiment, the fastening means 9 and 9 'are on the upper rigid body 4. This may advantageously have dimensions in width (its width being along the axis y illustrated in Figure 1) higher to those of the lower longitudinal rigid body 5, so as to increase the contact surface with the transport module to be attached. To improve the strength of the module, fastening means 9 may for example be located at the front portion of the upper rigid body 4 (as shown in Figures 1 and 2) and fixing means 9 'can be located at the of the rear portion of the upper rigid body 4 (as shown in Figures 3a and 3b). The fastening means may for example consist of notches and clips systems, without for all that being limiting. The fixing means will be chosen from among various mechanical devices ensuring a solid and reliable attachment of a load transport module on the upper rigid body 4. For example, the bodies making up the deformable parallelogram mechanism will mainly consist of steel or aluminum. The upper longitudinal rigid body 4 may have a length (along the axis x illustrated in FIG. 1) of between 30 and 70 cm, a width (along the y axis) of between 2 and 20 cm and a thickness (according to FIG. z axis) between 10 and 30 mm; advantageously, it will respectively have dimensions of 45 cm, 10 cm and 20 mm. The lower rigid longitudinal body 5 may have a length of between 30 and 70 cm, a width of between 2 and 20 cm and a thickness of between 10 and 30 mm; advantageously, it will have respectively dimensions 45 cm, 3 cm and 20 mm. The transverse rigid lateral bodies 7,8 may have dimensions along the y and z axes, between 5 and 10 cm, and a dimension along the x axis of between 2 and 5 cm; advantageously, it will respectively have dimensions of 7 cm, 8 cm and 3 cm.
    The central rigid body 6 is in rotational connection with the two longitudinal bodies 4,5, at their central part. It extends in height (along the z axis) at the rear part of the rigid longitudinal bodies 4,5. For example, the height extension of the central rigid body 6 may have dimensions along the x and z axes between 9 and 11 cm and between 15 and 25 cm respectively, and a dimension along the y axis between 1 and 4 cm; advantageously, it will respectively have dimensions of 10 cm, 25 cm and 2 cm.
    Alternatively, a retractable stand can be fixed on the central rigid body 6, so as to ensure a better stability of the front train 1 (integral or not with a pedal cycle) parking.
    As illustrated in FIGS. 3a and 3b, the front axle according to the invention also comprises a damping spring system with dry friction 12. It may advantageously consist of a damper system with blades 12, composed of two sets of blades each comprising at least two flexible blades, whose intrinsic flexural capacity depends on the material of which they are composed and their thickness. For example, each blade may be made of steel, and have a thickness of between 0.5 and 3 mm. The adjustment of the number of blades constituting the damping spring system may allow to adapt the rigidity of the system, the damping effect being related to the friction between the blades.
    Each set of blades constituting the blade damper system 12 has an end secured to the central rigid body 6 at a fastening element 13; the other end of each set of blades is supported by retaining guides 14, 14 'arranged in lateral part (respectively on the right for one set of blades and on the left for the other set of blades), on one of the substantially horizontal longitudinal rigid bodies 4,5. According to the first embodiment, the holding guides 14, 14 'are on the lower rigid body 5 (as illustrated in FIGS. 3a and 3b). Each guide 14, 14 'consists for example of two metal cylinders arranged so as to guide the ends of the blade set, leaving it to the possibility of sliding slightly longitudinally. In case of inclination of the central rigid body 6, the blade of the damping system 12 flexes (as shown in Figure 3b) and will firstly dampen the tilting movement of the central rigid body 6 (damper effect via the friction between the blades); on the other hand, the blade of the damping system 12 will tend to resume its rest position (not flexed) and thus to return the central rigid body 6 in the central equilibrium position (spring effect).
    In order to easily adjust the damping and spring effects of the damping system 12, for a given set of blades (number of blades, thickness and material thereof), the longitudinal position (along the x axis) of the guides 14.14 'on the lower rigid body 5 can be adjusted.
    The smaller the distance between the fastening element 13 and each holding guide 14, 14 ', the greater the damping and springing effects will be.
    The front train 1 according to the first embodiment can be fixed on a pedal cycle, for example on a conventional bicycle, and thus turn it into a tricycle. It is first necessary to remove the front wheel of the bicycle that you want to transform, and disconnect the front brake cables.
    Figure 4 shows a simplified kinematic diagram of the front axle 1 fixed on the steering fork 30 of said bicycle. It is the central rigid body 6 which is secured with the steering fork 30, in two attachment zones 20 and 21. The first attachment zone 20 is formed at the two legs of the steering fork 30 and a housing 10 arranged in the central rigid body 6: an axis slid in the notches and the housing 10 and blocked by screwing elements ensures the connection between the fork 30 and the central rigid body 6. Advantageously, the central rigid body 6 may have several housings 10, at different heights (along the z-axis, as shown in Figure 1), allowing the front train 1 to attach to multiple sizes of fork or bicycle. The second attachment zone 21 is above the first attachment zone 20 (along the z-axis).
    The central rigid body 6 may advantageously comprise an additional arm 6 'for extending the central rigid body 6 upwards. This additional arm 6 'will preferably be adjustable in height. Alternatively, the central rigid body 6 can be developed in a single block including the arm 6 '.
    As illustrated in FIG. 5, the second fastening zone 21 is formed at the level of the two sleeves of the steering fork 30 and of the additional arm 6 'by a universal fastening element 11. This element 11 may for example consist of a system jaws 110, clamped on the sleeves of the fork by a rod 111.
    According to a variant and in particular for bicycles equipped with jaw brakes having two attachment points on the fork legs, the element 11 may consist of a plate with through notches for screwing the element 11 in place of said brakes. . The fixing element 11 may advantageously be fixed on the additional arm 6 '. The arm 6 'being adjustable in height, it will be possible to fix the element 11 on multiple sizes of forks or bicycle, while maintaining a substantially horizontal orientation of the rigid longitudinal bodies 4,5.
    Thanks to the two attachment zones 20, 21, the front axle 1 according to the first embodiment of the invention is integral with the fork 30 of the cycle in at least 3 points of support, to ensure their joining in a plane .
    All that remains is to connect the brake cables of the front axle 1 to the braking controls that are attached to the handlebars of the cycle. The front train 1 according to the invention thus makes it possible to transform a bicycle into a tricycle in a simple and fast manner.
    The steering fork 30 being integral with the central rigid body 6, the rotational movements and inclination thereof are transmitted to the two front wheels through the deformable parallelogram mechanism. The damping spring system 12 with dry friction dampens these movements and help the recovery of the fork 30 in the central position, thus ensuring a more flexible and comfortable ride to the user.
    According to a second embodiment of the invention, the central rigid body 6 of the front axle 1 has a shape adapted to form directly the fork or the steering column of a cycle. The front train 1 according to this second embodiment can then be incorporated in a cycle structure (frame, pedal, rear wheel, handlebar, ...) for the manufacture of a tricycle.
    The front axle 1 according to the second embodiment comprises, as in the first embodiment, the two wheels 2,3, the deformable parallelogram mechanism of which one of the substantially horizontal longitudinal bodies 4,5 comprises fastening means 9 9 'for securing a load-bearing module 15, 15', 15 '', and the dry-friction damping spring system 12. The central rigid body 6 directly constituting the fork, the attachment zones 20 and 21 as well as that the elements 10 and 11 are not present.
    According to a variant, applicable to the first and second embodiments, the front axle 1 further comprises a load transport module 15, 15 ', 15' ', as illustrated in FIGS. 6a, 6b and 6c. The tricycle equipped with the front train 1 according to the invention can thus be transformed into a scooter. The module 15, 15 ', 15' 'is secured to the front axle 1 by virtue of the fastening elements 9, 9' arranged on the longitudinal (substantially horizontal) rigid upper body 4. By way of example, the module may consist of a platform 15, shown in Figure 6a. It can carry different types of loads, such as cases, bags or other objects that can be fixed on said platform 15 by tensioners or other means.
    The module may also consist of a carriage 15 ', shown in Figure 6b, particularly suitable for transporting errands, clothes or other miscellaneous objects. The module may also consist of a box 15 '' shown in Figure 6c, arranged to carry one or two children.
    Advantageously, these modules will also be configured to be used independently of the front train 1 of the scooter; for example, the carriage 15 'and the box 15' 'may be provided with wheels and gripping means allowing the user to pull or push them when separated from the front train 1.
    The module 15,15 ', 15' 'being only fixed on the upper rigid body 4, it does not follow the axis of the fork 30 during the movements of inclination thereof (corresponding to a rotation along the axis y). As illustrated in FIG. 7, the center of gravity of the module (symbolized by G2 in FIG. 7) follows the movement of the upper rigid body 4, linked to the deformable parallelogram mechanism: it undergoes a slight inclination with respect to the perpendicular axis to the upper rigid body 4, in the opposite direction to the inclination of the steering fork 30. This kinematics is particularly advantageous to ensure good driving comfort for the user of the scooter, especially in the case of heavy loads transport. .
    Indeed, in the case of a load integral with the steering fork 30, the weight PI of the load (whose center of gravity is symbolized by G1 in FIG. 7) generates a moment M proportional to the sinus of the inclination of the fork 30. This results in a significant effort required to return the fork 30 to its central position. By making the load integral with the upper rigid body 4 (the load being symbolized by G2 in FIG. 7), the tilting of the load is reduced, which makes it possible to provide less effort to return the fork to the initial position.
    Because of this kinematics and thanks to the damping spring system with dry friction 12, the front axle 1 according to the invention provides maneuverability and driving comfort very close to a bicycle, with in addition the stability and the transport capacity a scooter.
    The front train 1 of a pedal cycle according to the invention can find multiple uses such as: - go to his place of work, with the possibility of carrying personal or professional effects - make business trips eg delivery , in an urban or peri-urban setting - moving inside an extensive industrial site, with the possibility of carrying objects or files easily - taking the children to school, - going shopping,
    Of course, the invention is not limited to the embodiments described and variants can be made without departing from the scope of the invention as defined by the claims.
