Description

CYCLE PLIABLE  FOLDING CYCLE
[οοοΐ ] La présente invention revendique la priorité de la demande française 1357367 déposée le 25 juillet 2013 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. [0002] L'invention concerne le domaine des cycles pliables. [οοοΐ] The present invention claims the priority of the French application 1357367 filed July 25, 2013 whose content (text, drawings and claims) is here incorporated by reference. The invention relates to the field of foldable cycles.
[0003] Afin de permettre un déplacement simplifié dans les grandes agglomérations, on connaît des vélos pouvant être pliés afin de diminuer leur encombrement pour être transportés à la main dans un transport en commun (métro, bus, etc.) ou être placés dans un coffre de véhicule automobile. Ainsi, le vélo comporte une position dépliée d'utilisation et une position pliée de stockage. To allow a simplified movement in large cities, we know bicycles can be folded to reduce their size to be transported by hand in a public transport (metro, bus, etc.) or placed in a motor vehicle trunk. Thus, the bike has an unfolded position of use and a folded storage position.
[0004] Pour permettre le pliage du vélo, on connaît dans l'art antérieur un vélo comportant un cadre en deux parties reliées par une articulation afin de permettre aux deux cadres d'être superposés en position de stockage. A titre d'exemple, on connaît un vélo dont une première partie de cadre est reliée à une deuxième partie de cadre par un axe vertical de manière à ce que le cadre se plie dans un plan horizontal. Une telle articulation nécessite une zone de pliage/dépliage importante autour du vélo étant donné que les parties du cadre se déplacent dans un plan horizontal selon un mouvement en arc de cercle. Aussi, un tel vélo présente des inconvénients lorsqu'il est utilisé dans un environnement urbain, par exemple, à proximité d'un trottoir ou d'un accès à un métro. [0005] Afin d'éliminer cet inconvénient, on connaît par le document GB2414972 un vélo comportant un cadre arrière, un cadre intermédiaire et un cadre avant. Le cadre arrière et le cadre avant sont chacun reliés au cadre intermédiaire par une articulation permettant, d'une part, une rotation selon un axe horizontal et, d'autre part, une translation selon ledit axe horizontal de manière à ce que le cadre arrière, le cadre intermédiaire et le cadre avant soient parallèles en position de stockage. To allow folding of the bicycle, there is known in the prior art a bicycle having a frame in two parts connected by a hinge to allow the two frames to be superimposed in the storage position. By way of example, a bicycle is known whose first frame portion is connected to a second frame portion by a vertical axis so that the frame folds in a horizontal plane. Such articulation requires a large folding / unfolding area around the bicycle since the parts of the frame move in a horizontal plane in an arcuate motion. Also, such a bicycle has disadvantages when used in an urban environment, for example, near a sidewalk or access to a metro. To eliminate this drawback, document GB2414972 discloses a bicycle comprising a rear frame, an intermediate frame and a front frame. The rear frame and the front frame are each connected to the intermediate frame by an articulation allowing, on the one hand, a rotation along a horizontal axis and, on the other hand, a translation along said horizontal axis so that the rear frame , the intermediate frame and the front frame are parallel in the storage position.
[0006] Un tel vélo avec un cadre en trois parties et deux articulations est complexe à réaliser, ce qui augmente son coût de fabrication. En effet, chaque articulation comporte deux cames qui coopèrent pour assurer, d'une part, une rotation selon un axe horizontal et, d'autre part, une translation selon ledit axe horizontal. En outre, un ressort est monté entre les deux cames pour les maintenir ensemble et éviter un pliage malencontreux. En pratique, pour plier le vélo, un utilisateur doit exercer une force s'opposant à la force élastique du ressort tout en tournant l'une des cames par rapport à l'autre. De telles opérations sont peu pratiques à mettre en œuvre, ce qui présente un inconvénient. Ces opérations de pliage sont en outre longues à mettre en œuvre étant donné qu'un utilisateur doit les réaliser pour les deux articulations du vélo. Enfin, les cames ne permettent pas un guidage optimal d'un cadre par rapport à l'autre, ce qui diminue la durée de vie des articulations et, par voie de conséquence, celle du vélo. Such a bicycle with a three-part frame and two joints is complex to achieve, which increases its manufacturing cost. Indeed, each articulation comprises two cams which cooperate to ensure, on the one hand, a rotation along a horizontal axis and, on the other hand, a translation along said horizontal axis. In addition, a spring is mounted between the two cams to hold them together and prevent unfortunate folding. In practice, to fold the bike, a user must exert a force opposing the force resilient spring while rotating one cam relative to the other. Such operations are impractical to implement, which has a disadvantage. These folding operations are also long to implement since a user must make them for both joints of the bike. Finally, the cams do not allow optimal guidance of one frame relative to the other, which reduces the life of the joints and, consequently, that of the bike.
[0007] L'invention a donc pour but de remédier à ces inconvénients en proposant un cycle pouvant être plié de manière rapide et pratique dans une zone réduite et possédant une durée de vie importante. [0008] A cet effet, l'invention concerne un cycle comportant un premier élément de cadre sur lequel est montée une première roue et un deuxième élément de cadre sur lequel est montée une deuxième roue, le premier élément de cadre et le deuxième élément de cadre étant reliés par une pièce de liaison configurée pour permettre la rotation et la translation autour d'un axe horizontal de liaison du premier élément de cadre par rapport au deuxième élément de cadre. The invention therefore aims to overcome these disadvantages by providing a cycle that can be folded quickly and conveniently in a small area and having a long service life. For this purpose, the invention relates to a cycle comprising a first frame member on which is mounted a first wheel and a second frame member on which is mounted a second wheel, the first frame member and the second frame member. frame being connected by a connecting piece configured to allow rotation and translation about a horizontal connecting axis of the first frame member relative to the second frame member.
[0009] Le cycle est remarquable en ce que la pièce de liaison est solidaire du deuxième élément de cadre et comporte au moins une fente de guidage configurée pour coopérer avec au moins un doigt de guidage solidaire du premier élément de cadre. The cycle is remarkable in that the connecting piece is integral with the second frame member and comprises at least one guide slot configured to cooperate with at least one guide pin integral with the first frame member.
[ooi o] Ainsi, le déplacement relatif des éléments de cadre est parfaitement défini par la coopération de la fente de guidage avec le doigt de guidage. Aucune manipulation complexe et peu pratique ne doit être réalisée par un utilisateur pour plier/déplier un vélo. De plus, la dimension et la forme de la fente de guidage peut être aisément réglée pour permettre un pliage pratique et ne dépendant pas des dimensions du cadre. De manière avantageuse, les roues du cycle sont parallèles en position pliée de stockage de manière à permettre au cycle de rouler lors de son transport. [ooi o] Thus, the relative displacement of the frame members is perfectly defined by the cooperation of the guide slot with the guide finger. No complex and impractical manipulation should be performed by a user to fold / unfold a bike. In addition, the size and shape of the guide slot can be easily adjusted to allow convenient folding and does not depend on the dimensions of the frame. Advantageously, the wheels of the cycle are parallel in the folded storage position so as to allow the cycle to roll during its transport.
[001 1 ] De préférence, le cycle ne comporte qu'une unique pièce de liaison. Autrement dit, le cadre ne comporte que deux éléments de cadre, ce qui accélère son pliage par comparaison à un cadre comportant trois éléments. [001 1] Preferably, the cycle comprises only a single connecting piece. In other words, the frame has only two frame elements, which accelerates its folding compared to a frame with three elements.
[0012] De manière préférée, la dimension axiale de ladite fente de guidage selon l'axe horizontal de liaison définit la course en translation du premier élément de cadre par rapport au deuxième élément de cadre. Ainsi, en paramétrant la dimension axiale de la fente, on paramètre la translation selon l'axe horizontal de liaison, ce qui est avantageux pour s'adapter aux différentes épaisseurs de cadre. Preferably, the axial dimension of said guide slot along the horizontal connecting axis defines the displacement in translation of the first frame member relative to the second frame member. Thus, by setting the axial dimension of the slit, we set the translation along the horizontal axis of connection, which is advantageous to adapt to different frame thicknesses.
[0013] De manière préférée, la dimension angulaire de ladite fente de guidage autour de l'axe horizontal de liaison définit la course en rotation du premier élément de cadre par rapport au deuxième élément de cadre. Ainsi, en paramétrant la dimension angulaire de la fente, on paramètre la rotation selon l'axe horizontal de liaison, ce qui est avantageux pour s'adapter aux différentes formes de cadre et à l'écartement entre les deux roues du cycle. Preferably, the angular dimension of said guide slot around the horizontal connecting axis defines the rotational stroke of the first frame member relative to the second frame member. Thus, by parameterizing the angular dimension of the slot, the rotation is set along the horizontal axis of connection, which is advantageous for adapting to the different frame shapes and to the spacing between the two wheels of the cycle.
[0014] De préférence, la fente longitudinale possède une forme d'hélice de manière à réaliser simultanément une translation et une rotation autour de l'axe horizontal de liaison. [0015] De préférence, la pièce de liaison se présente sous la forme d'une pièce cylindrique s'étendant selon l'axe horizontal de liaison, ladite pièce de liaison comportant une enveloppe cylindrique dans laquelle est formée la fente de guidage. Une telle enveloppe cylindrique confère une robustesse importante à la pièce de liaison et permet, en outre, de former une pluralité de fentes de guidage, ce qui améliore le guidage. [0016] Selon un aspect de l'invention, le premier élément de cadre comporte un logement cylindrique s'étendant selon l'axe horizontal de liaison adapté pour recevoir la pièce de liaison. La coopération d'une pièce de liaison cylindrique avec un logement cylindrique permet de s'affranchir de tout mouvement non désiré, en particulier un mouvement transversal à l'axe horizontal de liaison, et d'augmenter la robustesse de la liaison. Preferably, the longitudinal slot has a helical shape so as to simultaneously perform a translation and a rotation about the horizontal connecting axis. Preferably, the connecting piece is in the form of a cylindrical piece extending along the horizontal connecting axis, said connecting piece having a cylindrical casing in which is formed the guide slot. Such a cylindrical envelope gives the connection piece a high degree of strength and, in addition, makes it possible to form a plurality of guide slots, which improves the guiding. According to one aspect of the invention, the first frame member comprises a cylindrical housing extending along the horizontal connecting axis adapted to receive the connecting piece. The cooperation of a cylindrical connecting piece with a cylindrical housing makes it possible to overcome any unwanted movement, in particular a movement transverse to the horizontal axis of connection, and to increase the robustness of the connection.
[0017] De préférence, ledit doigt de guidage est solidaire dudit logement cylindrique. Preferably, said guide pin is integral with said cylindrical housing.
[0018] Selon un aspect de l'invention, le cycle comprend des moyens de blocage manuel du premier élément de cadre par rapport au deuxième élément de cadre en position d'utilisation du cycle. Ainsi, tout pliage involontaire est évité. [0019] De préférence encore, les moyens de blocage manuel sont montés dans le deuxième élément de cadre. According to one aspect of the invention, the cycle comprises manual locking means of the first frame member relative to the second frame member in the use position of the cycle. Thus, any involuntary folding is avoided. More preferably, the manual locking means are mounted in the second frame member.
[0020] De manière préférée, les moyens de blocage manuel comportent une portion en saillie adaptée pour coopérer avec une fente de blocage du premier élément de cadre. [0021 ] Selon un aspect préféré, la pièce de liaison est montée de manière amovible au deuxième élément de cadre. Ainsi, on peut adapter la pièce de liaison en fonction du pliage désiré. Preferably, the manual locking means comprise a projecting portion adapted to cooperate with a locking slot of the first frame member. According to a preferred aspect, the connecting piece is removably mounted to the second frame member. Thus, one can adapt the connecting piece according to the desired bending.
[0022] L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et se référant aux dessins annexés sur lesquels : la figure 1 est une vue en perspective éclatée d'un cycle comprenant un premier élément de cadre, un deuxième élément de cadre et une pièce de liaison ; la figure 2 est une vue en perspective rapprochée de la pièce de liaison de la figure 1 ; · la figure 3 est une vue en perspective du cycle lors du montage des éléments de cadre ; la figure 4 est une vue en coupe de la pièce de liaison lorsque le cycle est en position pliée de stockage ; et la figure 5 est une vue en coupe de la pièce de liaison lorsque le cycle est en position dépliée d'utilisation. The invention will be better understood on reading the description which follows, given solely by way of example, and with reference to the accompanying drawings, in which: FIG. 1 is an exploded perspective view of a cycle comprising a first frame member, a second frame member, and a link member; Figure 2 is a close perspective view of the connecting piece of Figure 1; FIG. 3 is a perspective view of the cycle during assembly of the frame elements; Figure 4 is a sectional view of the connecting piece when the cycle is in the folded storage position; and Figure 5 is a sectional view of the connecting piece when the cycle is in the unfolded position of use.
[0023] Il faut noter que les figures exposent l'invention de manière détaillée pour mettre en œuvre l'invention, lesdites figures pouvant bien entendu servir à mieux définir l'invention le cas échéant. It should be noted that the figures disclose the invention in detail to implement the invention, said figures can of course be used to better define the invention where appropriate.
[0024] En référence à la figure 1 , il est représenté un cycle comportant un premier élément de cadre 1 sur lequel est montée une première roue 10 et un deuxième élément de cadre 2 sur lequel est montée une deuxième roue (non représentée). Dans cet exemple, le premier élément de cadre 1 correspond à la partie avant du cycle tandis que le deuxième élément de cadre 2 correspond à la partie arrière du cycle. Le cadre ne comporte avantageusement que deux parties pour accélérer son pliage. [0025] Toujours en référence à la figure 1 , le premier élément de cadre 1 et le deuxième élément de cadre 2 sont reliés par une pièce de liaison 3 configurée pour permettre la rotation et la translation autour d'un axe horizontal de liaison X du premier élément de cadre 1 par rapport au deuxième élément de cadre 2. [0026] Dans cet exemple, en référence aux figures 1 et 2, la pièce de liaison 3 se présente sous la forme d'une pièce cylindrique s'étendant selon l'axe horizontal de liaison X et comportant une enveloppe cylindrique 33 s'étendant axialement dans laquelle sont formées deux fentes de guidage 30 diamétralement opposées. [0027] Comme illustré à la figure 1 , la pièce de liaison 3 comporte une paroi annulaire 34 s'étendant transversalement à l'axe horizontal X adaptée pour être solidarisée au deuxième élément de cadre 2. Dans cet exemple, la paroi annulaire 34 comporte une pluralité d'orifices de fixation 31 et le deuxième élément de cadre 2 comporte une pluralité d'orifices de fixation 21 pour permettre le passage de vis de fixation 7 (représentées aux figures 4 et 5) afin de solidariser ensemble la pièce de liaison 3 avec le deuxième élément de cadre 2. De préférence, la pièce de liaison 3 est montée de manière amovible par rapport au deuxième élément de cadre 2 afin de faciliter l'assemblage du cycle. Referring to Figure 1, there is shown a cycle having a first frame member 1 on which is mounted a first wheel 10 and a second frame member 2 on which is mounted a second wheel (not shown). In this example, the first frame element 1 corresponds to the front part of the cycle while the second frame element 2 corresponds to the rear part of the cycle. The frame advantageously comprises only two parts to accelerate its folding. Still with reference to Figure 1, the first frame member 1 and the second frame member 2 are connected by a connecting piece 3 configured to allow rotation and translation about a horizontal axis X connection of the first frame element 1 with respect to the second frame element 2. In this example, with reference to Figures 1 and 2, the connecting piece 3 is in the form of a cylindrical piece extending along the horizontal axis of X connection and having a cylindrical casing 33 extending axially in which are formed two diametrically opposed guide slots 30. As illustrated in Figure 1, the connecting piece 3 comprises an annular wall 34 extending transversely to the horizontal axis X adapted to be secured to the second frame member 2. In this example, the annular wall 34 comprises a plurality of fixing holes 31 and the second frame member 2 comprises a plurality of fixing holes 21 to allow the passage of fastening screws 7 (shown in FIGS. 4 and 5) so as to fasten together the connecting piece 3 with the second frame member 2. Preferably, the connecting piece 3 is removably mounted relative to the second frame member 2 to facilitate assembly of the cycle.
[0028] En référence aux figures 1 et 2, l'enveloppe cylindrique 33 de la pièce de liaison 3 comporte des fentes de guidage 30 configurées pour coopérer respectivement avec des doigts de guidage 6 solidaires du premier élément de cadre 1 . En référence à la figure 2, une fente de guidage 30 comporte une dimension axiale D, définie selon l'axe horizontal de liaison X, qui correspond à la course en translation du premier élément de cadre 1 par rapport au deuxième élément de cadre 2. En pratique, la dimension axiale D du concept en position fermé est comprise entre 100 mm et 220 mm, de préférence, ici de l'ordre de 170 mm With reference to FIGS. 1 and 2, the cylindrical casing 33 of the connecting piece 3 comprises guide slots 30 configured to cooperate respectively with guide fingers 6 integral with the first frame member 1. With reference to FIG. 2, a guide slot 30 has an axial dimension D, defined along the horizontal axis of connection X, which corresponds to the translation displacement of the first frame element 1 relative to the second frame element 2. In practice, the axial dimension D of the concept in the closed position is between 100 mm and 220 mm, preferably, here of the order of 170 mm
Mécaniquement. Une bonne tenue mécanique de l'ensemble en position ouverte du concept demande un rapport x1 .5 entre le diamètre du pivot général et la longueur Axiale D D = diamètre pivot X1 .5 Mechanically. A good mechanical strength of the assembly in the open position of the concept requires a ratio x1 .5 between the diameter of the general pivot and the axial length D D = pivot diameter X1 .5
[0029] Toujours en référence à la figure 2, une fente de guidage 30 comporte une dimension angulaire A, définie autour l'axe horizontal de liaison X, qui correspond à la course en rotation du premier élément de cadre 1 par rapport au deuxième élément de cadre 2. En pratique, la dimension angulaire A est comprise entre 60 0 et 150 ° , de préférence, ici de l'ordre de 95 ° . Still with reference to Figure 2, a guide slot 30 has an angular dimension A, defined around the horizontal axis X connection, which corresponds to the rotational stroke of the first frame member 1 relative to the second element In practice, the angular dimension A is between 60 ° and 150 °, preferably here about 95 °.
[0030] Dans cet exemple, chaque fente 30 s'étend sensiblement dans un même plan de manière à ce que, lors du déplacement du premier élément de cadre 1 par rapport au deuxième élément de cadre 2, une rotation soit accompagnée simultanément d'une translation selon l'axe horizontal de liaison X. De préférence, la fente de guidage possède une forme d'hélice. Néanmoins, il va de soi que la fente de guidage 30 pourrait posséder une forme différente, en particulier une forme de S ou de L, afin de dissocier les mouvements de rotation et de translation. Par exemple, lorsque la fente de guidage 30 possède une forme de L, la rotation est consécutive à la translation. [0031 ] Comme illustré à la figure 1 , le premier élément de cadre 1 comporte un logement cylindrique 4 s'étendant selon l'axe horizontal de liaison X adapté pour recevoir intérieurement la pièce de liaison 3. Le logement cylindrique 4 est ici usiné avec le premier élément de cadre 1 mais il pourrait également être rapporté sur ce dernier. Le logement cylindrique 4 comporte une enveloppe cylindrique 40 comportant deux ouvertures radiales 41 adaptées pour recevoir des doigts de guidage 6. Après assemblage, les doigts de guidage 6 s'étendent radialement à l'intérieur du logement cylindrique 4 afin de s'engager dans les fentes de guidage 30 comme cela sera présenté par la suite. Dans cet exemple, un doigt de guidage 6 se présente sous la forme d'une vis longitudinale comme illustré aux figures 4 et 5. De préférence, l'extrémité du doigt de guidage 6 montée dans la fente de guidage 30 est formée en un matériau glissant, de préférence, en polymère afin de diminuer les frictions lors du guidage. De tels doigts de guidage 6 sont avantageusement amovibles de manière à permettre leur remplacement en cas d'usure. In this example, each slot 30 extends substantially in the same plane so that, during the displacement of the first frame member 1 relative to the second frame member 2, a rotation is accompanied simultaneously by a translation along the horizontal axis of connection X. Preferably, the guide slot has a helix shape. Nevertheless, it goes without saying that the guide slot 30 could have a different shape, in particular a shape of S or L, in order to dissociate the rotational and translational movements. For example, when the guide slot 30 has an L shape, the rotation is consecutive to the translation. As illustrated in Figure 1, the first frame member 1 comprises a cylindrical housing 4 extending along the horizontal axis of the X connection adapted to receive internally the connecting piece 3. The cylindrical housing 4 is here machined with the first frame element 1 but it could also be reported on the latter. The cylindrical housing 4 comprises a cylindrical casing 40 having two radial openings 41 adapted to receive guide fingers 6. After assembly, the guide fingers 6 extend radially inside the cylindrical housing 4 in order to engage in the guide slots 30 as will be presented later. In this example, a guide pin 6 is in the form of a longitudinal screw as illustrated in FIGS. 4 and 5. Preferably, the end of the guide pin 6 mounted in the guide slot 30 is formed of a material sliding, preferably in polymer to reduce friction during guiding. Such guiding fingers 6 are advantageously removable so as to allow their replacement in case of wear.
[0032] Autrement dit, les doigts de guidage 6 sont solidaires du premier élément de cadre 1 et s'étendent dans les fentes de guidage 30 du deuxième élément de cadre 2 de manière à guider le déplacement en rotation et en translation des éléments de cadre 1 , 2. Une telle liaison est robuste et évite tout déplacement relatif non désiré, ce qui augmente la durée de vie du cycle. En outre, on peut paramétrer aisément la forme de la fente de guidage 30 pour plier rapidement et aisément un cycle en tenant compte de ses dimensions et de son encombrement. [0033] De manière préférée, le cycle comprend des moyens de blocage manuel 5 du premier élément de cadre 1 par rapport au deuxième élément de cadre 2 en position d'utilisation du cycle. Ainsi, tout pliage involontaire du cycle est évité. In other words, the guide fingers 6 are integral with the first frame member 1 and extend in the guide slots 30 of the second frame member 2 so as to guide the rotational and translational movement of the frame members. 1, 2. Such a connection is robust and avoids any undesired relative displacement, which increases the service life of the cycle. In addition, the shape of the guide slot 30 can be easily parameterized to fold quickly and easily a cycle taking into account its dimensions and its bulk. Preferably, the cycle comprises manual locking means 5 of the first frame member 1 relative to the second frame member 2 in the use position of the cycle. Thus, any involuntary folding of the cycle is avoided.
[0034] En référence à la figure 1 , les moyens de blocage manuel 5 sont montés dans le deuxième élément de cadre 2, de préférence, en translation selon un axe orthogonal à l'axe horizontal de liaison X. Referring to Figure 1, the manual locking means 5 are mounted in the second frame member 2, preferably in translation along an axis orthogonal to the horizontal axis X connection.
[0035] Dans cet exemple, en référence à la figure 1 , les moyens de blocage manuel 5 comportent une portion en saillie 52 adaptée pour s'étendre consécutivement dans une fente de blocage 42 formée dans l'enveloppe cylindrique 40 du logement cylindrique 4 du premier élément de cadre 1 et dans une fente de blocage 32 formée dans l'enveloppe cylindrique 33 de la pièce de liaison 3 du deuxième élément de cadre 2. Ainsi, lorsque l'élément en saillie 52 des moyens de blocage 5 s'étend à travers les fentes de blocage 32, 42, tout déplacement relatif du premier élément de cadre 1 par rapport au deuxième élément de cadre 2 est interdit. In this example, with reference to Figure 1, the manual locking means 5 comprise a projecting portion 52 adapted to extend consecutively in a locking slot 42 formed in the cylindrical casing 40 of the cylindrical housing 4 of the first frame member 1 and in a locking slot 32 formed in the cylindrical casing 33 of the connecting piece 3 of the second frame member 2. Thus, when the protruding member 52 of the locking means 5 extends through the locking slots 32, 42, any relative movement of the first frame member 1 relative to the second frame member 2 is prohibited.
[0036] De préférence, les moyens de blocage 5 se présentent sous la forme d'une pièce mécanique montée dans une cavité 22 du deuxième élément de cadre 2 afin que la portion en saillie 52 s'étende au niveau de la pièce de liaison 3. Les moyens de blocage 5 comportent, dans cet exemple, une manette 51 , dont la forme est adaptée pour recevoir l'extrémité d'un doigt d'un utilisateur, qui est accessible dans la cavité 22 pour commander la translation de la portion en saillie 52 dans les fentes de blocage 32, 42. Il va de soi que d'autres moyens de blocage pourraient convenir. Preferably, the locking means 5 are in the form of a mechanical part mounted in a cavity 22 of the second frame member 2 so that the projecting portion 52 extends at the connecting piece 3 The locking means 5 comprise, in this example, a handle 51, the shape of which is adapted to receive the end of a user's finger, which is accessible in the cavity 22 to control the translation of the portion protrusion 52 in the locking slots 32, 42. It goes without saying that other locking means could be suitable.
[0037] Pour monter le cycle, la pièce de liaison 3 est solidarisée au deuxième élément de cadre 2 puis la pièce de liaison 3 est placée dans le logement cylindrique 4 du premier élément de cadre 1 comme illustré à la figure 3. Ainsi, l'enveloppe cylindrique 40 s'étend entre l'élément en saillie 52 des moyens de blocage 5 et la pièce de liaison 3. To mount the cycle, the connecting piece 3 is secured to the second frame member 2 and the connecting piece 3 is placed in the cylindrical housing 4 of the first frame member 1 as shown in Figure 3. Thus, the cylindrical casing 40 extends between the projecting element 52 of the blocking means 5 and the connecting piece 3.
[0038] Ensuite, en référence à la figure 3, les doigts de guidage 6 sont introduits radialement depuis l'extérieur du logement 4 afin de s'étendre respectivement dans les fentes de guidage 30. Then, with reference to FIG. 3, the guide fingers 6 are introduced radially from the outside of the housing 4 so as to extend respectively in the guide slots 30.
[0039] Comme illustré à la figure 4, les doigts de guidage 6 ne comportent pas de portion en saillie radiale vers l'extérieur par rapport au logement cylindrique 4 de manière à permettre une rotation du deuxième cadre 2 sur la surface extérieure du logement cylindrique 4 lors du pliage. En effet, les ouvertures radiales 41 de l'enveloppe cylindrique 40 sont dimensionnées pour, d'une part, bloquer radialement les têtes des doigts de guidage 6 et, d'autre part, éviter la formation d'un relief au niveau de l'enveloppe cylindrique 40 du logement cylindrique 4 comme illustré aux figures 4 et 5. As illustrated in FIG. 4, the guide fingers 6 do not comprise a portion protruding radially outwardly relative to the cylindrical housing 4 so as to allow a rotation of the second frame 2 on the outer surface of the cylindrical housing. 4 when folding. Indeed, the radial openings 41 of the cylindrical envelope 40 are sized to, firstly, radially block the heads of the guide fingers 6 and, secondly, to avoid the formation of a relief at the level of the cylindrical casing 40 of the cylindrical housing 4 as illustrated in FIGS. 4 and 5.
[0040] En référence à la figure 4 représentant le cycle en position pliée, le logement cylindrique 4 du premier cadre 1 est fixe et possède un doigt de guidage 6 s'étendant fixement dans la fente de guidage 30 de la pièce de liaison 3 solidaire du deuxième élément de cadre 2. Comme illustré à la figure 4, le logement cylindrique 4 permet un guidage précis et robuste de la pièce de liaison 3. En position pliée de stockage, la pièce de liaison 3 s'étend partiellement dans le logement cylindrique 4. Une telle position permet de positionner parallèlement les roues avant et arrière du cycle. Ainsi, un utilisateur peut faire rouler le cycle en position pliée de stockage, ce qui est pratique et donc avantageux. Referring to Figure 4 showing the cycle in the folded position, the cylindrical housing 4 of the first frame 1 is fixed and has a guide pin 6 extending fixedly in the guide slot 30 of the connecting piece 3 solidaire of the second frame member 2. As illustrated in Figure 4, the cylindrical housing 4 allows a precise and robust guidance of the connecting piece 3. In folded storage position, the piece link 3 extends partially in the cylindrical housing 4. Such a position makes it possible to position the front and rear wheels of the cycle in parallel. Thus, a user can roll the cycle in folded storage position, which is convenient and therefore advantageous.
[0041 ] Lors du pliage, le deuxième élément de cadre 2 se déplace relativement au premier élément de cadre 1 . La fente de guidage 30, solidaire du deuxième élément de cadre 2, se déplace relativement au doigt de guidage 6, solidaire du premier élément de cadre 1 . Du fait de la forme de la fente de guidage 30, le deuxième élément de cadre 2 est guidé en translation et en rotation autour de l'axe horizontal X de manière à ce que le deuxième élément de cadre 2 soit aligné avec le premier élément de cadre 1 en position dépliée d'utilisation. En position dépliée, la pièce de liaison 3 s'étend entièrement dans le logement cylindrique 4. Le logement cylindrique 4 offre un guidage robuste en empêchant tout déplacement transversal non désiré. When folding, the second frame member 2 moves relative to the first frame member 1. The guide slot 30, integral with the second frame element 2, moves relative to the guide pin 6, integral with the first frame element 1. Because of the shape of the guide slot 30, the second frame member 2 is guided in translation and in rotation about the horizontal axis X so that the second frame member 2 is aligned with the first frame member. frame 1 in unfolded position of use. In the unfolded position, the connecting piece 3 extends entirely into the cylindrical housing 4. The cylindrical housing 4 provides robust guidance by preventing any undesired transverse displacement.
[0042] Pour sécuriser la position dépliée, les moyens de blocage 5 sont déplacés manuellement par le doigt de l'utilisateur. Un tel blocage n'est possible que lorsque la position dépliée est atteinte étant donné que les fentes de blocage 32, 42 doivent être alignées pour permettre l'insertion de la portion en saillie 52. To secure the unfolded position, the blocking means 5 are moved manually by the finger of the user. Such locking is possible only when the unfolded position is reached since the locking slots 32, 42 must be aligned to allow insertion of the projecting portion 52.
[0043] Il va de soi que le premier élément de cadre du cycle pourrait correspondre à la partie arrière du cycle de manière à ce que la pièce de liaison soit solidaire de la partie arrière du cycle. [0044] De manière préférée, le cycle comportant un pédalier et un guidon, la pièce de liaison 3 est située entre ledit pédalier et ledit guidon. Un tel positionnement permet d'éviter qu'un utilisateur ne se salisse les mains étant donné que la zone située entre le pédalier et le guidon est peu sujette aux salissures. It goes without saying that the first frame element of the cycle could correspond to the rear part of the cycle so that the connecting piece is secured to the rear part of the cycle. Preferably, the cycle comprising a pedal and a handlebar, the connecting piece 3 is located between said pedal and said handlebar. Such positioning prevents a user from getting dirty hands since the area between the pedal and the handlebar is not prone to soiling.
