Description

BYCYCLE UNIVERSEL PLIANT SUSPENDU UNIVERSAL SUSPENDED FOLDING BYCYCLE
La présente invention concerne un bicycle, c'est-à-dire un cycle dont les deux roues sont de diamètres différents, la plus petite étant placée à l'avant.The present invention relates to a bicycle, that is to say a cycle in which the two wheels are of different diameters, the smallest being placed at the front.
Il est pliant, possède une suspension, est mixte, toutes tailles, d'un usage extérieur et intérieur, car accouplé à un accessoire, il se transforme rapidement en vélo d'appartement, d'où son universalité et son modernisme.It is folding, has a suspension, is mixed, all sizes, for outdoor and indoor use, because coupled with an accessory, it quickly turns into an exercise bike, hence its universality and modernism.
Il est maniable, léger, performant et de faible encombrement ( moins d'un mètre ), plié comme déplié, et les transformations qui le caractérisent sont rapides et aisées.It is handy, light, efficient and compact (less than a meter), folded as unfolded, and the transformations that characterize it are quick and easy.
Traditionnellement, un cycle pliant utilise une articulation qui brise son cadre, afin de réduire sa longueur. Ce système modifie soit l'alignement des deux roues, soit l'empâtement, ce qui nuit à la rigidité de l'ensemble, à l'utilisation.Traditionally, a folding cycle uses a joint that breaks its frame to reduce its length. This system modifies either the alignment of the two wheels or the wheelbase, which affects the rigidity of the assembly, in use.
Le dispositif selon l'invention permet de remédier à cet inconvénient en ce qu'il ne modifte pas, lors du pliaige, la structure de la partie essentielle du vélo, c'est-à-dire les roues, la direction et la transmission.The device according to the invention overcomes this drawback in that it does not modify, during folding, the structure of the essential part of the bicycle, that is to say the wheels, the steering and the transmission.
Au pédalage, ce système offre une meilleure rigidité grâce à l'alignement immuable des pièces en rotation. De plus il est dépourvu de haubans arrières ce qui permet le montage et le démontage de la chaîne sans avoir à briser celle-ci.When pedaling, this system offers better rigidity thanks to the immutable alignment of the rotating parts. In addition it is devoid of rear shrouds which allows the assembly and disassembly of the chain without having to break it.
Le cycle présenté réduit donc ses dimensions au pliage, dans le sens de la hauteur. Sa conception innovante lui permet, une fois plié, d'être transporté dans le coffre à bagages de tout véhicule automobile, y compris le plus petit actuellement sur le marché. Enfin, grâce à un accessoire - dispositif d'entraînement à domicile - , ce cycle, de par son architecture, se transforme rapidement et facilement en vélo d'appartement stable, d'un encombrement minimum, et à position d'utilisation réglable.The cycle presented therefore reduces its dimensions to folding, in the direction of height. Its innovative design allows it, when folded, to be transported in the luggage compartment of any motor vehicle, including the smallest currently on the market. Finally, thanks to an accessory - home training device - this cycle, by virtue of its architecture, quickly and easily transforms into a stable exercise bike, with a minimum footprint, and with an adjustable use position.
Les dessins annexés illustrent l'invention : La figure 1 représente le bicycle dans sa position d'usage sur la voie publique. La figure 2 représente le bicycle dans sa fonction vélo d'appartement, fixé sur son accessoire - dispositif d'entraînement à domicile - , représenté en vue de face. La figure 3 représente ce même accessoire en vue de dessus. La figure 4 représente la phase n° 1 du pliage La figure 5 représente la phase n° 2 du pliage La figure 6 représente le bicycle entièrement plié.The accompanying drawings illustrate the invention: Figure 1 shows the bicycle in its position of use on the public highway. Figure 2 shows the bicycle in its exercise bike function, attached to its accessory - home training device -, shown in front view. Figure 3 shows the same accessory in top view. Figure 4 shows phase 1 of folding Figure 5 shows phase 2 of folding Figure 6 shows the fully folded bicycle.
En référence à ces dessins, le système de pliage consiste en trois opérations de desserrage de dispositifs à blocage rapide. La première consiste à déverrouiller la base de l'amortisseur (1), à faire glisser ce dernier entre les bras de la fourche arrière (2) et abaisser le bras mobile (3) sur la roue arrière (4).With reference to these drawings, the folding system consists of three operations for loosening quick-locking devices. The first consists of unlocking the base of the shock absorber (1), sliding the latter between the arms of the rear fork (2) and lowering the mobile arm (3) on the rear wheel (4).
La seconde consiste à déverrouiller le blocage rapide du collier qui bloque la tige de selle (5) pour amener la selle (6) dans sa position la plus basse.The second is to unlock the quick release of the collar that blocks the seatpost (5) to bring the saddle (6) to its lowest position.
La dernière, après déverrouillage selon le même système, consiste à abattre vers l'arrière la tige support de guidon (7) - qui sert également de poignée de transport - afin de clipser celle-ci sur l'anneau prévu à cet effet (8), et fixé sur le bras mobile (3). L'opération totale de pliage n'aura pris que quelques secondes. La transformation en vélo d'appartement consiste en un simple démontage de la roue avant (9), à poser la roue arrière (4) sur les rouleaux de l'accessoire, et fixer la fourche avant sur l'étrier de l'accessoire et la bloquer par serrage d'un système à blocage rapide. Là encore, en quelques secondes, la transformation est réalisée.The last, after unlocking according to the same system, consists in knocking down the handlebar support rod (7) towards the rear - which also serves as a transport handle - in order to clip it onto the ring provided for this purpose (8 ), and fixed on the movable arm (3). The entire folding operation will only take a few seconds. The conversion to a stationary bike consists of a simple disassembly of the front wheel (9), to put the rear wheel (4) on the rollers of the accessory, and to fix the front fork on the bracket of the accessory and lock it by tightening a quick release system. Again, in seconds, the transformation is completed.
\ Le cadre de ce cycle, réalisé en alliage d'aluminium est constitué de deux parties principales, l'une fixe, l'autre mobile.\ The frame of this cycle, made of aluminum alloy, consists of two main parts, one fixed, the other mobile.
La première, partie fixe , est constituée d'une courte poutre de section rectangulaire (10) sur laquelle est soudée la douille de direction (11) d'un côté et la boîte de pédalier (12) de l'autre. De cette dernière partent les deux bases de section triangulaire de préférence (rigidité) qui constituent la fourche arrière (2), soudées elles aussi, et portant à chaque extrémité les pattes de fixation de la roue arrière (4) de 16 pouces. Ces deux bases sont reliées entre elles, à l'avant de la roue arrière (4) par une plaque soudée, qui reçoit un support en U (13), percé sur le côté de part en part pour recevoir un axe et un blocage rapide, et percé sur le fond pour y fixer éventuellement un frein à mâchoires traditionnel. La base de gauche portera éventuellement des pattes de fixation pour un système de freinage à disque. ï La patte droite de fixation de la roue arrière sera conçue pour recevoir un éventuel dérailleur.The first, fixed part, consists of a short beam of rectangular section (10) on which is welded the steering bush (11) on one side and the bottom bracket (12) on the other. From the latter leave the two bases of triangular section preferably (stiffness) which constitute the rear fork (2), also welded, and carrying at each end the lugs for fixing the rear wheel (4) of 16 inches. These two bases are connected together, at the front of the rear wheel (4) by a welded plate, which receives a U-shaped support (13), drilled on the side from side to side to receive an axle and quick locking , and drilled on the bottom to eventually attach a traditional jaw brake. The base on the left will eventually have mounting brackets for a disc brake system. ï The right rear wheel mounting lug will be designed to accommodate a possible derailleur.
La douille de direction (11), soudée à un angle déterminé, supportera un jeu de roulement de direction, de préférence intégré, et supportera la courte fourche avant à deux fourreaux (14) maintenant la roue avant (9) de 8 pouces.The steering bush (11), welded at a determined angle, will support a steering bearing set, preferably integrated, and will support the short two-legged front fork (14) holding the 8-inch front wheel (9).
La deuxième partie du cadre, bras mobile (3), réalisée par pliage et soudure dans le même matériau, est de section rectangulaire et arbore un profil de parallélogramme à longue base et faible hauteur. A une extrémité, elle porte deux pattes soudées et percées (15), à l'autre extrémité un tube (16) soudé et fendu dans sa partie haute, servant à recevoir la tige de selle (5) ainsi qu'un collier de serrage. A une cote donnée, un perçage (17) est effectué de part en part. Une ouverture (18) est aussi pratiquée sur la face inférieure, sous le perçage (17) pour insérer la tête de l' amortisseur (19).The second part of the frame, mobile arm (3), produced by folding and welding in the same material, is of rectangular section and has a parallelogram profile with long base and low height. At one end, it carries two welded and drilled tabs (15), at the other end a tube (16) welded and split in its upper part, used to receive the seatpost (5) as well as a clamp . At a given dimension, drilling (17) is carried out right through. An opening (18) is also made on the underside, under the bore (17) to insert the head of the shock absorber (19).
Ces deux parties du cadre sont reliées entre elles par un axe (25), qui traverse la poutre et les deux pattes (15), derrière la douille de direction ; elles sont reliées également par l'amortisseur (1), à longueur et tarage déterminés, afin de respecter la triangulation et d' assurer un confort supplémentaire à l'utilisateur. Le sommet de cet amortisseur (19) est fixé tournant, grâce à un axe passant dans le perçage (17) du bras mobile.These two parts of the frame are interconnected by an axis (25), which passes through the beam and the two legs (15), behind the steering bush; they are also connected by the shock absorber (1), at determined length and calibration, in order to respect the triangulation and to provide additional comfort to the user. The top of this shock absorber (19) is fixed rotating, thanks to an axis passing through the bore (17) of the movable arm.
La base de cet amortisseur, en forme de cavalier, viendra reposer sur un axe équipé d'un dispositif de serrage à blocage rapide traversant le support en U (13).The base of this shock absorber, in the form of a jumper, will come to rest on an axis fitted with a quick-locking clamping device passing through the U-shaped support (13).
La transmission est traditionnelle, pédalier, chaîne, pignon avec un développement adapté aux parcours plats et faiblement vallonnés.The transmission is traditional, crankset, chain, pinion with a development adapted to flat and slightly hilly routes.
Pour diriger le cycle, une potence (20) , supporte un tube articulé (7) sur lequel est soudé, en haut, un guidon droit et étroit (21), et en bas, deux pattes (22) soudées et percées supportant un dispositif cranté (23) et un système de serrage à blocage rapideTo direct the cycle, a bracket (20) supports an articulated tube (7) on which is welded, at the top, a straight and narrow handlebar (21), and at the bottom, two legs (22) welded and drilled supporting a device notched (23) and a quick release clamping system
Ce dispositif cranté est constitué : -^d'un cylindre dont les deux faces comportent des crans (une vingtaine), usinés en étoile. Il est bloqué traditionnellement dans la potence (20),This notched device is made up of: - ^ a cylinder, the two faces of which have notches (around twenty), machined into a star. It is traditionally blocked in the gallows (20),
- de deux rondelles, crantées de la même manière, sur une face, et soudées à l'intérieur des deux pattes (22),- two washers, notched in the same way, on one side, and welded inside the two legs (22),
- d'un axe de système à blocage rapide qui traverse le cylindre, les rondelles et les deux pattes, pour bloquer ou débloquer le dispositif.- a quick-release system axis which passes through the cylinder, the washers and the two tabs, to block or unblock the device.
Sur le tube (7), à une distance donnée, un manchon caoutchouté (24) est placé pour une préhension adéquate, lors du transport du cycle plié.On the tube (7), at a given distance, a rubberized sleeve (24) is placed for an adequate grip, during the transport of the folded cycle.
Enfin, pour transformer le cycle en vélo d'appartement, un dispositif d'entraînement à domicile est nécessaire. Il est réalisé en tubes de section carrée assemblés par soudure. La partie arrière forme un cadre rectangulaire recevant deux rouleaux montés sur roulements à bille et fixés sur quatre pattes soudées à entraxes déterminés.Finally, to transform the cycle into an exercise bike, a home training device is necessary. It is made of square section tubes assembled by welding. The rear part forms a rectangular frame receiving two rollers mounted on ball bearings and fixed on four legs welded at determined centers.
De ce cadre part un tube terminé par un T, et qui supporte un cavalier muni d'un système de serrage à blocage rapide destiné à bloquer la fourche avant. Pour répondre à une utilisation sur la voie publique, l'invention sera équipée d'un système d'éclairage, de catadioptres latéraux, d'un éventuel deuxième frein, de garde- boue, d'une sonnette, et pour une praticabilité optimale, un panier d'une grande profondeur pourra être placé à l'avant. From this frame leaves a tube terminated by a T, and which supports a rider provided with a quick-locking clamping system intended to block the front fork. To respond to use on public roads, the invention will be equipped with a lighting system, lateral reflectors, a possible second brake, mud flaps, a bell, and for optimum practicability, a basket of great depth can be placed at the front.
