Description

Cadre de vélo comprenant une unique barre supérieure et une unique barre inférieure  Bicycle frame comprising a single upper bar and a single lower bar
L'invention concerne un cadre de vélo ainsi qu'un vélo comprenant un tel cadre. The invention relates to a bicycle frame and a bicycle comprising such a frame.
Un cadre de vélo est généralement formé par association de différents tubes selon une géométrie permettant le montage notamment des roues, d'un système d'entraînement, d'une selle et d'un ensemble de direction. En particulier, le cadre est formé par disposition et association respectives des différents tubes pour obtenir la géométrie souhaitée, lesdites associations étant notamment réalisées par soudure, brasage ou collage. A bicycle frame is generally formed by combining different tubes according to a geometry allowing the assembly including wheels, a drive system, a saddle and a set of direction. In particular, the frame is formed by respective arrangement and association of the different tubes to obtain the desired geometry, said associations being in particular made by welding, brazing or gluing.
Selon une réalisation, le cadre comprend un tube de selle de part et d'autre duquel s'étendent une structure avant comprenant un tube de direction portant le train avant et une structure arrière de montage de la roue arrière en la connectant au système d'entraînement. According to one embodiment, the frame comprises a seat tube on either side of which extend a front structure comprising a steering tube carrying the front axle and a rear rear wheel mounting structure by connecting it to the steering system. training.
De façon conventionnelle, la structure avant présente une barre supérieure et une barre inférieure reliant les tubes de selle et de direction suivant une géométrie, par exemple sensiblement triangulaire, qui est agencée pour conférer au cadre la rigidité attendue. Conventionally, the front structure has an upper bar and a lower bar connecting the seat and steering tubes in a geometry, for example substantially triangular, which is arranged to give the frame the expected rigidity.
Par ailleurs, la structure arrière comprend deux montants latéraux formés chacun d'un hauban et d'une base qui sont reliés en une extrémité arrière portant un moyen d'association de la roue, lesdits montants étant positionnés respectivement d'un côté de ladite roue pour assurer son association en entraînement. Toutefois, du fait du nombre de tubes utilisés, de telles structures de cadre présentent un poids important. En outre, la multiplicité des tubes à assembler génère un temps de fabrication élevé ainsi qu'un risque accru de dispersion géométrique dans les cadres obtenus. Pour réduire le nombre de tubes, le document DE-10 2007 038 109 propose un cadre de vélo comprenant une unique barre supérieure et une unique barre inférieure à l'arrière desquelles s'étendent en un seul tube cintré respectivement un hauban et une base qui sont disposés de part et d'autre de la roue arrière du vélo. Furthermore, the rear structure comprises two lateral uprights each formed of a stay and a base which are connected to a rear end carrying a means of association of the wheel, said uprights being positioned respectively on one side of said wheel. to ensure his association in training. However, because of the number of tubes used, such frame structures have a significant weight. In addition, the multiplicity of tubes to be assembled generates a high manufacturing time and an increased risk of geometric dispersion in the frames obtained. To reduce the number of tubes, document DE-10 2007 038 109 proposes a bicycle frame comprising a single upper bar and a single lower bar at the back of which extend into a single bent tube respectively a stay and a base which are arranged on either side of the rear wheel of the bicycle.
Toutefois, une telle solution ne donne pas entière satisfaction en ce que la réalisation du cadre reste complexe, notamment au niveau du montage des tubes cintrés sur le tube de direction et sur le tube de selle, nécessitant plusieurs étapes notamment de perçage, d'assemblage et de fixation entre lesdits tubes. However, such a solution does not give complete satisfaction in that the realization of the frame remains complex, especially in the assembly of the bent tubes on the steering tube and the seat tube, requiring several stages including drilling, assembly and fixing between said tubes.
En particulier, cette réalisation propose des tubes de direction et de selle qui s'étendent au travers de passages formés dans les tubes cintrés pour former les structures respectivement avant et arrière du cadre. In particular, this embodiment proposes steering and saddle tubes which extend through passages formed in the bent tubes to form the structures respectively front and rear of the frame.
L'invention vise à perfectionner l'art antérieur en proposant notamment un cadre de vélo présentant un nombre de tubes réduits et dont la fabrication et l'assemblage sont simplifiés, et ce tout en garantissant la rigidité et la géométrie souhaitées pour ledit cadre. The invention aims to improve the prior art by providing in particular a bicycle frame having a reduced number of tubes and whose manufacture and assembly are simplified, and while ensuring the desired rigidity and geometry for said frame.
A cet effet, selon un premier aspect, l'invention propose un cadre de vélo comprenant un tube de selle relié à une unique barre supérieure et une unique barre inférieure, lesdites barres présentant chacune une extrémité avant portant une douille de direction, ledit cadre comprenant en outre un hauban et une base présentant chacun une extrémité arrière qui porte un moyen d'association à respectivement un côté d'une roue arrière dudit vélo, ledit hauban - respectivement ladite base - étant formé en un seul tube avec la barre supérieure - respectivement inférieure -, lesdits tubes supérieur et inférieur étant associés respectivement à un côté du tube de selle en s'étendant continûment de part et d'autre dudit tube de selle. Selon un deuxième aspect, l'invention propose un vélo comprenant un tel cadre dans la douille de direction duquel une fourche équipée d'un guidon et d'une roue avant est montée, ledit vélo comprenant une selle montée sur le tube de selle et un pédalier monté sous ledit tube de selle, une roue arrière étant montée entre le hauban et la base en étant associée à respectivement un moyen d'association. For this purpose, according to a first aspect, the invention provides a bicycle frame comprising a seat tube connected to a single upper bar and a single lower bar, said bars each having a front end carrying a direction sleeve, said frame comprising in addition a stay and a base each having a rear end which carries a means of association to one side respectively of a rear wheel of said bicycle, said stay - respectively said base - being formed in a single tube with the upper bar - respectively lower -, said upper and lower tubes being respectively associated with one side of the seat tube by extending continuously on either side of said seat tube. According to a second aspect, the invention provides a bicycle comprising such a frame in the steering sleeve of which a fork equipped with a handlebar and a front wheel is mounted, said bicycle comprising a saddle mounted on the seat tube and a crankset mounted under said seat tube, a rear wheel being mounted between the stay and the base being associated respectively with a means of association.
D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence aux figures annexées, dans lesquelles : Other features and advantages of the invention will appear in the description which follows, made with reference to the appended figures, in which:
- les figures 1 à 4 sont des représentations schématiques d'un cadre de vélo selon un mode de réalisation de l'invention, respectivement en perspective vue de l'avant (figure 1 ), de côté (figure 2), en perspective vue de dessus (figure 3) et de dessus (figure 4).  FIGS. 1 to 4 are diagrammatic representations of a bicycle frame according to an embodiment of the invention, respectively in perspective seen from the front (FIG. 1), from the side (FIG. 2), in perspective seen from above (figure 3) and from above (figure 4).
En relation avec ces figures, on décrit ci-dessous un cadre de vélo, par exemple pour vélo de type VTC ou VTT, formé par association de différents tubes permettant le montage des différents organes du vélo, notamment des roues, d'un système d'entraînement, d'une selle et d'un ensemble de direction. In connection with these figures, there is described below a bicycle frame, for example for bicycle type VTC or MTB, formed by association of different tubes for mounting the various components of the bicycle, including wheels, a system of training, a saddle and a set of direction.
Le cadre comprend un tube de selle 1 qui est monté de façon sensiblement verticale et est destiné à recevoir une tige de montage de la selle, ladite tige étant associée audit tube de selle préférentiellement de manière ajustable pour permettre le réglage de la hauteur de ladite selle. The frame comprises a seat tube 1 which is mounted substantially vertically and is intended to receive a seat mounting rod, said rod being associated with said seat tube preferably adjustably to allow the adjustment of the height of said saddle .
Le cadre présente également une douille de direction 2 destinée au montage du train avant du vélo et qui est disposée en avant du tube de selle 1 , ledit tube de selle et ladite douille définissant un plan sagittal P du cadre de vélo. The frame also has a steering sleeve 2 for mounting the front end of the bicycle and which is disposed forward of the seat tube 1, said seat tube and said sleeve defining a sagittal plane P of the bicycle frame.
La douille de direction 2 est agencée pour recevoir une fourche de fixation de la roue avant qui est montée dans ladite douille par exemple sur des roulements à billes qui forment le jeu de direction. L'extrémité supérieure de la fourche peut être équipée d'une potence d'association d'un guidon du vélo qui s'étend au- dessus de la douille de direction 2. En particulier, le cadre comprend une unique barre supérieure 3 et une unique barre inférieure 4 qui sont reliées au tube de selle 1 en présentant chacune une extrémité avant portant la douille de direction 2, lesdites barres s'étendant entre ledit tube de selle et ladite douille selon une géométrie définissant la taille dudit cadre. The steering sleeve 2 is arranged to receive a front wheel attachment fork which is mounted in said sleeve for example on ball bearings which form the headset. The upper end of the fork can be equipped with a stem of association of a handlebar of the bicycle which extends above the sleeve of direction 2. In particular, the frame comprises a single upper bar 3 and a single lower bar 4 which are connected to the seat tube 1 each having a front end carrying the steering sleeve 2, said bars extending between said seat tube and said socket according to a geometry defining the size of said frame.
En relation avec les figures 1 et 2, les barres supérieure 3 et inférieure 4 s'étendent entre la douille de direction 2 et le tube de selle 1 de manière respectivement sensiblement horizontale et oblique, formant une structure de cadre avant à géométrie sensiblement triangulaire pour permettre une rigidité de cadre suffisante. En variante, la barre supérieure 3 peut être plus ou moins inclinée vers l'arrière pour conférer au cadre la rigidité attendue. In relation with FIGS. 1 and 2, the upper and lower bars 4 extend between the direction sleeve 2 and the seat tube 1 respectively substantially horizontally and obliquely, forming a front frame structure with a substantially triangular geometry for allow sufficient frame rigidity. Alternatively, the upper bar 3 may be more or less inclined rearward to give the frame the expected rigidity.
En outre, le cadre comprend un hauban 5 et une base 6 latéraux qui sont destinés au montage de la roue arrière du vélo en la connectant au système d'entraînement, notamment aux composants de chaîne dudit système. In addition, the frame comprises a stay 5 and a base 6 side which are intended for mounting the rear wheel of the bicycle by connecting it to the drive system, including the chain components of said system.
Afin de limiter le nombre de tubes du cadre et son temps de fabrication, on prévoit un seul hauban 5 et une seule base 6 pour le montage de la roue arrière, ledit hauban et ladite base s'étendant de part et d'autre de ladite roue pour assurer son association en entraînement. In order to limit the number of tubes of the frame and its manufacturing time, there is provided a single stay 5 and a single base 6 for mounting the rear wheel, said stay and said base extending on either side of said wheel to ensure his association in training.
En particulier, le hauban 5 et la base 6 s'étendent respectivement de manière oblique depuis l'extrémité supérieure du tube de selle 1 et sensiblement horizontalement depuis l'extrémité inférieure dudit tube de selle, en présentant chacun un moyen d'association permettant le montage de la roue arrière entre ledit hauban et ladite base. In particular, the stay 5 and the base 6 extend respectively obliquely from the upper end of the seat tube 1 and substantially horizontally from the lower end of said seat tube, each having a means of association allowing the mounting the rear wheel between said stay and said base.
En relation avec la figure 1 , le hauban 5 et la base 6 présentent chacun une extrémité arrière portant un moyen d'association à respectivement un côté de la roue arrière. Chaque moyen d'association peut comprendre par exemple une patte de fixation 7 qui est pourvue d'une ouverture arrière de montage d'un axe de la roue arrière, ladite patte étant rapportée ou formée en une seule pièce avec respectivement le hauban 5 et la base 6. In connection with Figure 1, the stay 5 and the base 6 each have a rear end carrying a means of association to one side of the rear wheel respectively. Each association means may comprise, for example, a fastening lug 7 which is provided with a rear opening for mounting an axle. of the rear wheel, said tab being attached or formed in one piece with respectively the stay 5 and the base 6.
Le hauban 5 et la base 6 sont formés en une seule pièce avec les barres respectivement supérieure 3 et inférieure 4. Le cadre présente ainsi deux tubes principaux respectivement supérieur 8 et inférieur 9 qui sont reliés au tube de selle 1 en s'étendant entre la douille de direction 2 et respectivement un côté de la roue arrière, formant respectivement un ensemble barre supérieure 3 / hauban 5 et un ensemble barre inférieure 4 / base 6. The stay 5 and the base 6 are formed in one piece with the bars respectively upper 3 and lower 4. The frame thus has two main tubes respectively upper 8 and lower 9 which are connected to the seat tube 1 extending between the steering sleeve 2 and respectively one side of the rear wheel, respectively forming an upper bar 3 / stay 5 and a lower bar 4 / base 6 assembly.
En particulier, les tubes supérieur 8 et inférieur 9 sont chacun cintrés en présentant une portion coudée de part et d'autre de laquelle s'étendent le hauban 5 - respectivement la base 6 - et la barre supérieure 3 - respectivement inférieure 4. In particular, the upper tubes 8 and lower 9 are each bent having a bent portion on either side of which extend the stay 5 - respectively the base 6 - and the upper bar 3 - respectively lower 4.
En relation avec les figures, la forme des différents tubes 1 , 8, 9 et de la douille 2 du cadre est cylindrique, le hauban 5 et la base 6 présentant une extrémité arrière conique portant la patte 7 de fixation à la roue arrière qui est plane. Les tubes 1 , 8, 9 peuvent être réalisés à partir d'acier pour favoriser la rigidité et la résistance du cadre ou à partir d'aluminium ou d'un matériau composite, notamment à base de fibres de carbone, pour optimiser le poids dudit cadre. In connection with the figures, the shape of the various tubes 1, 8, 9 and the sleeve 2 of the frame is cylindrical, the stay 5 and the base 6 having a conical rear end carrying the lug 7 for attaching to the rear wheel which is plane. The tubes 1, 8, 9 may be made from steel to promote the rigidity and strength of the frame or from aluminum or a composite material, in particular based on carbon fibers, to optimize the weight of said frame.
Les tubes supérieur 8 et inférieur 9 sont associés respectivement à un côté du tube de selle 1 en s'étendant continûment de part et d'autre dudit tube de selle. Ainsi, le cadre est formé sans besoin d'opération de perçage et/ou de découpe des tubes 1 , 8, 9, simplifiant l'assemblage dudit cadre et favorisant la fiabilité dans la réalisation de sa géométrie. The upper tubes 8 and lower 9 are respectively associated with one side of the seat tube 1 by extending continuously on either side of said seat tube. Thus, the frame is formed without the need for drilling and / or cutting the tubes 1, 8, 9, simplifying the assembly of said frame and promoting reliability in the realization of its geometry.
Pour ce faire, on prévoit de disposer les extrémités avant des barres 3, 4 en les espaçant verticalement et en les décalant angulairement par rapport au plan sagittal P selon un angle respectif ou , 012 qui est agencé pour que chacune des barres 3, 4 s'étende dans un plan respectif Pi, P2 depuis la douille de direction 2 jusqu'au tube de selle 1 . Dans le mode de réalisation représenté, les angles ou, 012 entre les barres 3, 4 et le plan P sont sensiblement de même valeur, les plans Pi et P2 formant un angle réduit avec la verticale. En variante, un décalage angulaire différent peut être prévu entre chacun des barres 3, 4 et le plan P. To do this, provision is made to arrange the front ends of the bars 3, 4 by spacing them vertically and shifting them angularly with respect to the sagittal plane P at a respective angle or, 012 which is arranged so that each of the bars 3, 4 s extending in a respective plane Pi, P2 from the steering sleeve 2 to the seat tube 1. In the embodiment shown, the angles or, 012 between the bars 3, 4 and the plane P are substantially of the same value, the planes Pi and P2 forming a reduced angle with the vertical. Alternatively, a different angular offset can be provided between each of the bars 3, 4 and the plane P.
En particulier, les tubes supérieur 8 et inférieur 9 sont associés au tube de selle 1 et portent la douille de direction 2 par l'intermédiaire de connecteurs agencés pour relier lesdits tubes et ladite douille selon des inclinaisons et des angles prédéfinis, garantissant la géométrie souhaitée du cadre. In particular, the upper tubes 8 and lower 9 are associated with the seat tube 1 and carry the direction sleeve 2 by means of connectors arranged to connect said tubes and said sleeve according to inclinations and predefined angles, guaranteeing the desired geometry of the frame.
Le cadre comprend un connecteur avant 10 présentant un manchon vertical 1 1 dans lequel la douille de direction 2 est disposée et deux manchons arrière 12, 13 dans chacun desquels l'extrémité avant d'une barre 3, 4 est associée. En relation avec les figures 3 et 4, les manchons arrière 12, 13 s'étendent depuis le manchon vertical 1 1 en étant décalés angulairement, notamment d'un angle égal à respectivement ou et 012 de part et d'autre du plan P pour permettre de disposer les barres 3, 4 dans leur plan Pi, P2 respectif. En outre, le tube de selle 1 est associé aux tubes supérieur 8 et inférieur 9 par l'intermédiaire respectivement d'un connecteur supérieur 14 et d'un connecteur inférieur 15, lesdits connecteurs présentant chacun des moyens d'association d'un tube 8, 9 qui sont disposés de part et d'autre dudit tube de selle. Selon le mode de réalisation représenté, les connecteurs supérieur 14 et inférieur 15 présentent chacun un manchon vertical 16, 17 de montage autour de l'extrémité respectivement supérieure et inférieure du tube de selle 1 et un manchon latéral 18, 19 dans lequel le tube respectivement supérieur 8 et inférieur 9 est associé. The frame comprises a front connector 10 having a vertical sleeve 1 1 in which the direction sleeve 2 is disposed and two rear sleeves 12, 13 in each of which the front end of a bar 3, 4 is associated. In relation with FIGS. 3 and 4, the rear sleeves 12, 13 extend from the vertical sleeve 1 1 while being angularly offset, in particular by an angle equal to or respectively and 012 on either side of the plane P to allow to arrange the bars 3, 4 in their respective plane Pi, P2. In addition, the seat tube 1 is associated with upper tubes 8 and lower 9 respectively via an upper connector 14 and a lower connector 15, said connectors each having means for associating a tube 8 , 9 which are arranged on either side of said seat tube. According to the embodiment shown, the upper 14 and lower 15 connectors each have a vertical sleeve 16, 17 for mounting around the respectively upper and lower end of the seat tube 1 and a lateral sleeve 18, 19 in which the tube respectively upper 8 and lower 9 is associated.
En particulier, les manchons latéraux 18, 19 s'étendent horizontalement sur un côté gauche ou droit du manchon vertical 16, 17, en étant associés aux barres respectivement supérieure 3 et inférieure 4, plus précisément en avant des portions coudées des tubes respectivement supérieur 8 et inférieur 9. In particular, the lateral sleeves 18, 19 extend horizontally on a left or right side of the vertical sleeve 16, 17, being associated with the bars respectively upper 3 and lower 4, more precisely in front of the bent portions of the tubes respectively upper 8 and lower 9.
Avantageusement, les tubes 8, 9 peuvent être agencés pour que le hauban 5 et la base 6 s'étendent sensiblement dans le plan Pi , P2 des barres 3, 4 respectives. En variante, on peut prévoir de former le tube supérieur 8 et/ou le tube inférieur 9 avec respectivement un hauban 5 et une base 6 qui s'étendent vers l'extérieur ou l'intérieur par rapport au plan Pi , P2 respectif, selon les besoins du montage de la roue arrière. Advantageously, the tubes 8, 9 may be arranged so that the stay 5 and the base 6 extend substantially in the plane Pi, P2 of the bars 3, 4 respectively. Alternatively, it is possible to form the upper tube 8 and / or the lower tube 9 with respectively a stay 5 and a base 6 which extend outwardly or inwardly relative to the respective plane Pi, P2, according to the needs of mounting the rear wheel.
En particulier, le hauban 5 et la base 6 peuvent s'étendre du côté du tube de selle 1 sur lequel respectivement le tube supérieur 8 et le tube inférieur 9 sont associés, évitant ainsi un croisement desdits hauban et base derrière le tube de selle 1 pour permettre l'association de la roue arrière. Sur les figures, la base 6 s'étend du côté gauche du tube de selle 1 , depuis ledit tube jusqu'à la patte de fixation 7, facilitant ainsi l'intégration du côté droit du système d'entraînement du vélo. In particular, the stay 5 and the base 6 can extend to the side of the seat tube 1 on which respectively the upper tube 8 and the lower tube 9 are associated, thus avoiding a crossing of said stay and base behind the seat tube 1 to allow the association of the rear wheel. In the figures, the base 6 extends on the left side of the seat tube 1, from said tube to the attachment lug 7, thus facilitating the integration of the right side of the bike drive system.
Les connecteurs 10, 14, 15 peuvent être chacun réalisés en une seule pièce, par exemple à partir d'un matériau plastique, les différents manchons 1 1 , 12, 13, 16, 17, 18, 19 présentant une forme cylindrique complémentaire à celles des tubes 1 , 8, 9 et de la douille de direction 2. Les différents tubes 1 , 8, 9 et la douille 2 peuvent être associés aux manchons correspondants 1 1 , 12, 13, 16, 17, 18, 19 sans besoin de soudure ou de collage afin d'optimiser les coûts et les temps de fabrication du cadre. The connectors 10, 14, 15 may each be made in one piece, for example from a plastic material, the various sleeves 1 1, 12, 13, 16, 17, 18, 19 having a cylindrical shape complementary to those tubes 1, 8, 9 and the direction sleeve 2. The various tubes 1, 8, 9 and the sleeve 2 can be associated with the corresponding sleeves 1 1, 12, 13, 16, 17, 18, 19 without the need for welding or gluing to optimize the costs and manufacturing times of the frame.
En outre, on peut prévoir une association réversible des tubes 1 , 8, 9 aux connecteurs 10, 14, 15, permettant un montage et un démontage rapides et faciles du cadre par l'utilisateur, notamment dans le cas d'un vélo se présentant sous forme de kit. En particulier, les connecteurs 10, 14, 15 sont agencés pour permettre l'assemblage des tubes 1 , 8, 9 et de la douille 2 selon la géométrie prédéfinie pour le cadre, et ce sans risque de dispersion dans la disposition relative desdits tubes. Selon le mode de réalisation représenté, les tubes supérieur 8 et inférieur 9 sont montés dans les manchons arrière 12, 13 et latéraux 18, 19 par emmanchement puis fixés en position par vissage. En particulier, l'emmanchement des tubes 8, 9 peut être réalisé par rotation et translation desdits tubes dans les manchons correspondants 12, 13, 18, 19, le vissage étant réalisé au moyen de vis traversant lesdits manchons et lesdits tubes. In addition, it is possible to provide a reversible association of the tubes 1, 8, 9 to the connectors 10, 14, 15, allowing the user to quickly and easily mount and dismount the frame, particularly in the case of a bicycle presenting itself. in kit form. In particular, the connectors 10, 14, 15 are arranged to allow the assembly of the tubes 1, 8, 9 and the sleeve 2 according to the predefined geometry for the frame, and without risk of dispersion in the relative arrangement of said tubes. According to the embodiment shown, the upper tubes 8 and lower 9 are mounted in the rear sleeves 12, 13 and side 18, 19 by fitting and then fixed in position by screwing. In particular, the fitting of the tubes 8, 9 can be achieved by rotation and translation of said tubes in the corresponding sleeves 12, 13, 18, 19, the screwing being carried out by means of screws passing through said sleeves and said tubes.
Par ailleurs, les connecteurs 10, 14, 15 peuvent être équipés de moyens d'association d'autres organes et accessoires du vélo, tels la selle, les câbles de frein ou les phares. Le connecteur inférieur 15 peut ainsi être équipé de moyens de montage d'un pédalier du système d'entraînement et/ou le connecteur supérieur 14 peut être équipé de moyens de montage de la tige de selle dudit vélo. Moreover, the connectors 10, 14, 15 may be equipped with means for associating other members and accessories of the bicycle, such as the saddle, the brake cables or the headlights. The lower connector 15 can thus be equipped with means for mounting a pedal of the drive system and / or the upper connector 14 can be equipped with mounting means of the seat post of said bicycle.
En relation avec les figures, le connecteur inférieur 15 présente un boîtier 20 de montage du pédalier qui s'étend sous les manchons vertical 17 et latéral 19. Le connecteur supérieur 14 est équipé d'un collier de serrage 21 permettant le montage ajustable de la tige de selle afin de régler la hauteur de ladite tige au gabarit de l'utilisateur et/ou à la position d'exercice souhaitée, ledit collier étant formé dans la continuité supérieure du manchon vertical 16 dudit connecteur. In connection with the figures, the lower connector 15 has a housing 20 for mounting the pedal which extends under the vertical sleeves 17 and side 19. The upper connector 14 is equipped with a clamping collar 21 for the adjustable mounting of the seat post to adjust the height of said shank to the user's template and / or the desired exercise position, said collar being formed in the upper continuity of the upright sleeve 16 of said connector.
Afin d'optimiser la rigidité du cadre, on peut prévoir une deuxième base 22 qui s'étend du côté de la roue arrière qui est opposé à celui dans lequel s'étend la première base 6, ladite deuxième base s'étendant depuis le tube de selle 1 jusqu'à l'extrémité arrière du hauban 5. In order to optimize the stiffness of the frame, it is possible to provide a second base 22 which extends on the side of the rear wheel which is opposed to that in which the first base 6 extends, said second base extending from the tube from seat 1 to the rear end of the guy 5.
Selon le mode de réalisation représenté, la deuxième base 22 est rapportée entre le tube de selle 1 et l'extrémité arrière du hauban 5, en présentant une extrémité avant qui est associée audit tube de selle du même côté que le tube supérieur 8 et une extrémité arrière adjacente à celle dudit hauban. En particulier, l'extrémité arrière de la deuxième base 22 porte un moyen d'association à la roue arrière qui est complémentaire à celui du hauban 5. En relation avec la figure 2, le moyen d'association de la deuxième base 22 est une patte de fixation 23 présentant une ouverture arrière qui est superposée à celle de la patte de fixation 7 du hauban 5. According to the embodiment shown, the second base 22 is attached between the seat tube 1 and the rear end of the stay 5, having a front end which is associated with said seat tube on the same side as the upper tube 8 and a rear end adjacent to that of said stay. In particular, the rear end of the second base 22 carries means of association with the rear wheel which is complementary to that of the stay 5. With reference to FIG. 2, the means for associating the second base 22 is a fixing lug 23 having a rear opening which is superimposed on that of the fixing lug 7 of the stay 5.
Cette réalisation permet notamment de faciliter le montage de la chaîne d'entraînement entre le pédalier et la roue arrière, en ce que les pattes 7, 23 peuvent être écartées pour permettre la disposition de la chaîne autour de la deuxième base 22 pour être connectée à ladite roue, et ce sans ouverture de ladite chaîne. Ensuite, le serrage de la roue arrière entre d'une part les pattes 7, 23 et, d'autre part la patte gauche 7, induit un accouplement des pattes 7, 23 pour assurer l'association de ladite roue entre la base 6 et le hauban 5. This embodiment makes it possible in particular to facilitate the assembly of the drive chain between the pedal and the rear wheel, in that the lugs 7, 23 can be spaced apart to allow the arrangement of the chain around the second base 22 to be connected to said wheel, and without opening said chain. Then, the clamping of the rear wheel between on the one hand the lugs 7, 23 and, on the other hand the left lug 7, induces a coupling of the lugs 7, 23 to ensure the association of said wheel between the base 6 and the stay 5.
L'extrémité avant de la deuxième base 22 est associée au connecteur inférieur 15, de façon à travailler en torsion entre le boîtier de pédalier 20 et la patte 7 du hauban 5, permettant de renforcer la rigidité du cadre, notamment pour éviter les vrillages de la roue arrière. The front end of the second base 22 is associated with the lower connector 15, so as to work in torsion between the bottom bracket 20 and the tab 7 of the stay 5, to reinforce the rigidity of the frame, in particular to avoid the twists of Rear wheel.
