Abstract

The bicycle consists of a main frame with two tubes (1) and articulated handlebars (2), front forks (3) and saddle pillar (7), all folding about lockable articulated joints (4, 5, 9). It has front and rear wheels (6, 12), a drive (11) and pedals (13). The handlebars and front forks fold parallel to the frame, with the front wheel passing between the frame bars, and the saddle pillar folding down on to of the folded handlebars. The ends of the handlebars and pedals can also be folded parallel to the frame.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne une bicyclette pliante.  The present invention relates to a folding bicycle.

Les bicyclettes pliantes actuellement commercialisées présentent souvent un ou plusieurs inconvénients en utilisation. Elles peuvent manquer de rigidité, améliorée éventuellement au détriment d'un surpoids important. Plusieurs systèmes de pliage/dépliage conduisent à des grandes complexités et peuvent aboutir, le cas échéant, à des manipulations relativement longues, quelquefois difficiles, voire dangereuses (coincement des doigts, par exemple). D'autres modèles présentent même un défaut de compacité les rendant inaptes au transport en volume réduit (coffres de voiture, train, métropolitain, etc. ). Il arrive également que la complexité du modèle conduise son inventeur à utiliser des matériaux bas de gamme pour obtenir malgré tout un produit qui reste dans le prix du marché. Ce choix peut conduire à des défauts de fiabilité, éventuellement à des risques majeurs en terme de sécurité pour l'utilisateur.  The folding bicycles currently sold often have one or more drawbacks in use. They may lack rigidity, possibly improved at the expense of significant overweight. Several folding / unfolding systems lead to great complexities and can lead, if necessary, to relatively long manipulations, sometimes difficult, even dangerous (pinching of the fingers, for example). Other models even have a compactness defect making them unsuitable for transport in reduced volume (car trunks, train, metropolitan, etc.). It also happens that the complexity of the model leads its inventor to use low-end materials to obtain, despite everything, a product that remains at the market price. This choice can lead to reliability defects, possibly to major risks in terms of security for the user.

Le but de la présente invention est de proposer le meilleur compromis entre les caractéristiques de rigidité, de facilité d'utilisation, de poids et de simplicité de conception tout en visant le meilleur niveau de sécurité pour l'utilisateur.  The aim of the present invention is to propose the best compromise between the characteristics of rigidity, ease of use, weight and simplicity of design while aiming for the best level of security for the user.

La planche 1/5 présente la bicyclette en position dépliée prête à l'utilisation vue en perspective. Elle est constituée de : - un cadre poutre (1) comportant deux tubes parallèles.  Plate 1/5 shows the bicycle in the unfolded position ready for use, seen in perspective. It consists of: - a beam frame (1) comprising two parallel tubes.

- un guidon (2) avec ses poignées (14) liés au cadre par une articulation double (4) comprenant un dispositif de blocage rapide intégré.  - a handlebar (2) with its handles (14) linked to the frame by a double articulation (4) comprising an integrated rapid locking device.

- une fourche (3) liée au cadre par l'articulation double (4) et maintenue en position par le blocage rapide (5).  - a fork (3) linked to the frame by the double articulation (4) and held in position by the quick release (5).

- un tube de selle (7) comprenant la selle (8) relié au cadre par l'articulation (9) et maintenu en position par le blocage rapide (10) - un système d'entraînement (11) à courroie crantée comportant les pédales (13) - une roue avant (6).  - a seat tube (7) comprising the saddle (8) connected to the frame by the articulation (9) and held in position by the quick release (10) - a drive system (11) with toothed belt comprising the pedals (13) - a front wheel (6).

- une roue arrière (12) à moyeu intégré permettant le rétropédalage - un frein avant non représenté sur la figure mais nécessaire aux respect des normes de sécurité (l'éclairage et le timbre avertisseur obligatoires ne sont également pas représentés)  - a rear wheel (12) with integrated hub allowing coastering - a front brake not shown in the figure but necessary for compliance with safety standards (the lighting and the mandatory warning tone are also not shown)

L'opération de pliage de la bicyclette se déroule en 3 étapes.  The folding operation of the bicycle takes place in 3 stages.

La planche 2/5 met en évidence le pliage du guidon, il s'effectue par déverrouillage de l'articulation (4), pivotement du guidon (2) autour de l'articulation (4) pour venir en position plié parallèle au cadre (1) et reverrouillage de l'articulation (4).  Plate 2/5 highlights the folding of the handlebars, it is carried out by unlocking the articulation (4), pivoting of the handlebars (2) around the articulation (4) to come in the folded position parallel to the frame ( 1) and relocking of the joint (4).

La planche 3/5 met en évidence le pliage du tube de selle, il s'effectue par déverrouillage du blocage (10) pivotement du tube de selle (7) autour de l'articulation (9) pour venir en position plié parallèle au cadre et reverrouillage du blocage (10).  Plate 3/5 highlights the folding of the seat tube, it is carried out by unlocking the blocking (10) pivoting of the seat tube (7) around the joint (9) to come in the folded position parallel to the frame and relocking the blocking (10).

La planche 4/5 met en évidence le pliage de la fourche, il s'effectue par le déverrouillage du blocage (5), pivotement de la fourche (3) autour de l'articulation (4) pour venir en position pliée parallèle au cadre (1) et reverrouillage du blocage (5), la roue (6) trouvant sa place entre les deux tubes du cadre (1).  Plate 4/5 highlights the folding of the fork, it is carried out by unlocking the blocking (5), pivoting the fork (3) around the joint (4) to come in the folded position parallel to the frame (1) and relocking of the blocking (5), the wheel (6) finding its place between the two tubes of the frame (1).

La planche 5/5 montre par ailleurs la possibilité optionnelle de réduire l'encombrement en épaisseur de la bicyclette par pivotement des articulations à friction des poignées de guidon (14) et des pédales (13) autour de leurs axes pour venir en position pliée parallèle au cadre (1).  Plate 5/5 also shows the optional possibility of reducing the overall thickness of the bicycle by pivoting the friction joints of the handlebar grips (14) and pedals (13) around their axes so as to come in the folded parallel position. to the frame (1).

A titre indicatif, la bicyclette présentée sur les planches 1 à 5 comprend des roues de diamètre 14 pouces permettant d'aboutir à une compromis optimum entre stabilité, de la bicyclette dépliée et compacité de la bicyclette pliée. Cette bicyclette pliante peut toutefois s'envisager avec des roues de 12 ou de 16 pouces.  As an indication, the bicycle presented on the boards 1 to 5 comprises wheels of diameter 14 inches making it possible to reach an optimum compromise between stability, of the unfolded bicycle and compactness of the folded bicycle. This folding bicycle can however be considered with 12 or 16 inch wheels.

Le dépliage de la bicyclette se fait par déroulement inverse des opérations cidessus The unfolding of the bicycle is done by reverse sequence of the above operations
