Description

L'Addition, conformément au Brevet principal, concerne un véhicule propulsé par un système de pédales. The Addition, in accordance with the main patent, relates to a vehicle powered by a pedal system.

L'objet de l'Addition se rattache au secteur technique des véhicules et moyens de transport, aux jouets, aux matériels sportifs. The object of the Addition relates to the technical sector of vehicles and means of transport, toys, sports equipment.

Selon l'Addition, à partir de la conception de base du Brevet, il a été conçu et mis au point une réalisation selon laquelle le cadre est monté avec capacité de pivotement angulaire limite par rapport à la partie recevant l'axe des roues arrières et l'ensemble du système de transmission qui demeure fixe. According to the Addition, from the basic design of the Patent, it was designed and developed an embodiment according to which the frame is mounted with limited angular pivoting capacity relative to the part receiving the axis of the rear wheels and the entire transmission system which remains fixed.

On rappelle selon le Brevet, notamment la revendication
1, que le véhicule comprend un châssis monté d'une manière roues stable sur au moins trols rdont deux roues d'entratnement mon- tées parallèlement sur un même alignement axial et une roue avant directrice montée orientable par rapport au châssis avec des moyens de direction, les deux roues parallèles étant entrainées en rotation par un double système de manivelles opposées, chaque paire de manivelles étant solidaire d'un axe tournant dans un palier du châssis ; les manivelles correspondantes se trouvant d'un même côté des systèmes, portent chacune à leurs extrémités libres un organe ou partie d'appui solidaire d'un plateau pose-pied ; de chaque côté des deux systèmes, lesdits plateaux pose-pieds solidaires des organes ou parties d'appui, ayant une liberté de déplacement angulaire par rapport auxdits organes ou parties d'appui.According to the Patent, in particular the claim
1, that the vehicle comprises a chassis mounted in a stable wheel manner on at least three tracks including two drive wheels mounted in parallel on the same axial alignment and a front steering wheel mounted orientable 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 integral with a rotating axis in a bearing of the chassis; the corresponding cranks being on 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.

Ce mouvement de rotation de double système de manivelle est transmis aux roues arrières au moyen d'un pédalier d'une chaîne et d'au moins un pignon, le pédalier étant solidaire de l'axe relatif au système avant de manivelle. This rotation movement of the double crank system is transmitted to the rear wheels by means of a chain crankset and at least one sprocket, the crankset being integral with the axis relative to the front crank system.

Selon une première caractéristique de l'Addition, le cadre est réalisé en deux parties indépendantes, l'une des parties recevant notamment le double système de manivelles opposées avec les moyens de transmission aux roues arrières, tandis que l'autre partie qui reçoit essentiellement la roue avant directrice et les moyens de direction, est montée mobile avec capacité de déplacement angulaire limité sur ladite première partie. According to a first characteristic of the Addition, the frame is produced in two independent parts, one of the parts receiving in particular the double system of opposite cranks with the transmission means to the rear wheels, while the other part which essentially receives the front steering wheel and the steering means, is mounted mobile with limited angular displacement capacity on said first part.

D'autres caractéristiques ressortiront de la suite de la description. Other characteristics will emerge from the following description.

Les figures 6, 7 et 8 montrent l'ensemble du véhicule selon trois variantes de réalisation. Figures 6, 7 and 8 show the entire vehicle according to three alternative embodiments.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant sous des formes non limitatives de réaiisation illustrées aux figures des dessins. In order to make the object of the invention more concrete, it is now described in non-limiting forms of embodiment illustrated in the figures of the drawings.

On voit figure 1 que le châssis (C) est exécuté en deux parties distinctes (C6) et in7). La première partie (C6) reçoit le double système de manivelles opposées (5 - 6) et (7 - 8) équipé des repose-pieds (12 - 13) et ltensemble du système de transmission aux roues arrières (1) et (2), c'est-à-dire, essentiellement le pédalier (14), la chaîne (-15) et le pignon moteur (16) solidaire de l'arbre d'entraînement (17) desdites roues (1) et (2). We see in Figure 1 that the chassis (C) is executed in two distinct parts (C6) and in7). The first part (C6) receives the double system of opposite cranks (5 - 6) and (7 - 8) equipped with the footrests (12 - 13) and the entire transmission system to the rear wheels (1) and (2) , that is to say, essentially the bottom bracket (14), the chain (-15) and the drive pinion (16) integral with the drive shaft (17) of said wheels (1) and (2).

Dans ce but, la partie (C6) du châssis ou cadre (C), est réalisée à partir d-'un élément tubulaire médian (34) présentant en bout, une portée d'assemblage coaxiale (34a) et, à son extrémité opposée, un manchon horizontal (34b) disposé perpendiculairement aux génératrices de l'élément de base (34), ledit manchon étant agencé pour autoriser le montage à libre rotation de l'arbre (17). For this purpose, the part (C6) of the chassis or frame (C) is produced from a median tubular element (34) having at the end a coaxial assembly span (34a) and, at its opposite end , a horizontal sleeve (34b) disposed perpendicular to the generatrices of the base element (34), said sleeve being arranged to allow free rotation mounting of the shaft (17).

Sous l'élément tubulaire de base (34), sont fixés les deux paliers (p) dans lesquels sont montés tournants les axes de chaque paire de manivelles. La portée coaxiale d'assemblage (34a) présente deux lumières oblongues (34al) diamétralement opposées et délimitant une échancrure transversale (34a2) disposée horizontalement (figure 3)
De la même façon, la partie arrière du tube (34), entre le palier (p) et le manchon (3ab), présente deux lumières oblongues diamétralement opposées (3arc) délimitant une échancrure transversale interne (34cl) disposée dans un plan horizontal (figure 4) Ces deux échancrures (3au2) et (3acul) autorisent en combinaison ~ le montage et le pivotement angulaire limite de la deuxième partie du cadre (C7)o
Cette deuxième partie (C7) reçoit essentiellement la roue avant (3) et les moyens de direction A partir du tube de direction (4) sont montés un tube diagonal inférieur (35) et un tube diagonal supérieur (36) e chacun desdits tubes étant con- venablement cintré à leur extrémité libre A titre indicatif, le tube (35) fait un angle de 200 par rapport à I'horizontal, tandis que le tube (36), fait un angle de SOC
Le tube diagonal inferieur I35) est cintré en bout pour constituer une portée horizontale de centrage (35) susceptible d'être emmanché à fibre coulissement sur la portée coaxiale (34a). Le tube diagonal supérieur (36) est aussi cintré en bout à son extrémité libre pour constituer une branche verticale (36a) terminée par un étrier (36b) confornte' pour coiffer la section externe du tube de base (34) de la partie
(C6) du cadre.Under the basic tubular element (34) are fixed the two bearings (p) in which the axes of each pair of cranks are rotatably mounted. The coaxial assembly surface (34a) has two oblong slots (34al) diametrically opposite and delimiting a transverse notch (34a2) arranged horizontally (Figure 3)
In the same way, the rear part of the tube (34), between the bearing (p) and the sleeve (3ab), has two diametrically opposite oblong slots (3arc) delimiting an internal transverse notch (34cl) arranged in a horizontal plane ( Figure 4) These two notches (3au2) and (3acul) allow in combination ~ mounting and limit angular pivoting of the second part of the frame (C7) o
This second part (C7) essentially receives the front wheel (3) and the steering means From the steering tube (4) are mounted a lower down tube (35) and an upper down tube (36) and each of said tubes being conveniently bent at their free end As an indication, the tube (35) makes an angle of 200 relative to the horizontal, while the tube (36), makes an angle of SOC
The lower diagonal tube I35) is bent at the end to form a horizontal centering surface (35) capable of being fitted with sliding fiber onto the coaxial surface (34a). The upper diagonal tube (36) is also bent at the end at its free end to constitute a vertical branch (36a) terminated by a stirrup (36b) suitable for covering the external section of the base tube (34) of the part
(C6) of the frame.

La partie horizontale (35a)du tube (35) et les branches de l'étrier (36b) du tube (36)sont percées chacune de part en part respectivement en (35b) et (36c) pour le passage d'organes d'assemblage (37) coopérant avec les lumières correspondantes que présente l'élément de base (34). Il en résulte donc que la
partie (C7) du cadre est montée sur la partie (C6) avec une ca
pacité de pivotement angulaire limite.The horizontal part (35a) of the tube (35) and the branches of the stirrup (36b) of the tube (36) are each drilled right through at (35b) and (36c) respectively for the passage of organs of assembly (37) cooperating with the corresponding openings presented by the base element (34). It therefore follows that the
part (C7) of the frame is mounted on part (C6) with a ca
limit angular pivoting capacity.

On conçoit donc que l'ensemble du sytème d'entraînement
monté sur la partie (C6) du cadre est indépendante de la partie
avant (C7) et demeure fixe, de sorte que les repose-pieds
(12 et 13) restent stables. L'avant du véhicule (partie C7 du
cadre), qui est mobile angulairement, s'utilise comme une bi
cyclette et permet de prendre des virages rapidement et en tou
te sécurité.We can therefore see that the entire drive system
mounted on the part (C6) of the frame is independent of the part
front (C7) and remains fixed, so that the footrests
(12 and 13) remain stable. The front of the vehicle (part C7 of
frame), which is angularly movable, can be used as a bi
bicycle and allows you to take turns quickly and in any
security.

I1 est bien évident que le véhicule peut être équipé d'un panier porte-bagages à l'arrière (38) (figure 8 ), de
respose-pieds arrières fixes (39) pour une utilisation à deux
personnes, d'une selleyéventuellement , l'une quelconque de
ces variantes pouvant être combinées.It is obvious that the vehicle can be fitted with a rear basket basket (38) (Figure 8),
fixed rear footrests (39) for two-person use
people, possibly a saddle, any of
these variants can be combined.

On souligne que le manchon (34b) de l'élément de base
tubulaire (34) est déporté latéralement par rapport à l'axe dudit élément, le pignon moteur (16) étant monté du côté de
plus faible longueur.It is emphasized that the sleeve (34b) of the base element
tubular (34) is offset laterally relative to the axis of said element, the drive pinion (16) being mounted on the side of
shorter length.

Les avantages ressortent bien de la description, en par
ticulier on souligne
- Stabilité des repose-pieds facilitant l'utilisation du vé
hicule aux personnes qui ont perdu le sens de l'équilibre ,- Le système d'entraînement est utilisé dans des conditions normales évitant tout risque de torsion de la chaîne et de déverrouillage de cette dernière
- La stabilité des repose-pieds permet de supprimer les sangles de maintien.The advantages are apparent from the description, in par
particular we underline
- Stability of the footrests facilitating the use of the vee
hicle to people who have lost their sense of balance, - The drive system is used in normal conditions avoiding any risk of twisting the chain and unlocking it
- The stability of the footrests eliminates the support straps.

Enfin, on -souligne que les bras de manivelles sont de longueur réduite de l'ordre de 9 cm, de sorte que les
repose-pieds ont un niveau maximum d'appui de 18 cm, ce qui correspond, sur le plan ergonomique, à la hauteur d'une marche d'escalier courante, le corps humain étant parfaitement habitue à un tel écart.Finally, it is emphasized that the crank arms are of reduced length of the order of 9 cm, so that the
footrests have a maximum level of support of 18 cm, which corresponds, ergonomically, to the height of a common stair step, the human body being perfectly used to such a gap.

L'invention ne se limite aucunement à celui de ses modes d'application non plus qu'à ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées elle en embrasse au contraire toutes les variantes.  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 having been more especially indicated, on the contrary it embraces all variants.
