La figure 1 est une vue en élévation latérale d'une manivelle selon l'invention avec une pédale en position abaissée,FIG. 1 is a side elevation view of a crank according to the invention with a pedal in the lowered position,
La figure 2 est une vue en élévation frontale de la manivelle de la figure 1 avec un arrachement partiel, etFIG. 2 is a front elevation view of the crank of FIG. 1 with a partial cutaway, and
La figure 3 est une vue identique à celle de la figure 1 montrant la manivelle selon l'invention avec une pédale en position relevée Sur les figures 1 et 2 est représentée une manivelle 1 de pédalier de bicyclette selon l'inventionFigure 3 is a view identical to that of Figure 1 showing the crank according to the invention with a pedal in the raised position In Figures 1 and 2 is shown a crank 1 of bicycle crankset according to the invention
Cette manivelle 1 comprend d'une part une première partie 3 dans laquelle est ménagé un alésage 5 permettant la fixation de cette première partie 3 à un arbre de pédalier non représenté, et d'autre part une seconde partie 7 portant une pédale 9This crank 1 comprises on the one hand a first part 3 in which is formed a bore 5 allowing the fixing of this first part 3 to a pedal shaft not shown, and on the other hand a second part 7 carrying a pedal 9
Cette seconde partie 7 est déplaçable par l'intermédiaire d'une articulation 11 par rapport à ladite première partie 3 entre une position active (représentée sur la figure 1 ), également appelée position abaissée, dans laquelle la pédale 9 est sensiblement perpendiculaire à la manivelle et une position inactive (représentée sur la figure 3), également appelée position relevée, dans laquelle la pédale 9 est sensiblement parallèle à la manivelle 1This second part 7 is movable by means of an articulation 11 relative to said first part 3 between an active position (shown in FIG. 1), also called the lowered position, in which the pedal 9 is substantially perpendicular to the crank. and an inactive position (shown in FIG. 3), also called the raised position, in which the pedal 9 is substantially parallel to the crank 1
Ainsi que l'on voit sur les figures, l'articulation 11 comprend un axe orienté à la fois perpendiculaire à l'axe X-X de la manivelle et à l'axe Y- Y de la pédale 9 dans sa position abaissée ou activeAs can be seen in the figures, the articulation 11 comprises an axis oriented both perpendicular to the axis X-X of the crank and to the axis Y- Y of the pedal 9 in its lowered or active position
En outre, la manivelle 1 comprend des moyens 13 de verrouillage de la seconde partie 7 dans sa position abaissée Ces moyens 13 comprennent deux leviers de verrouillage 15 disposés sur des côtés latéraux opposés de la manivelle 1 et reçus respectivement dans un évidemment 17 ménagé dans la première partie 3 de la manivelle 1 et parallèle à l'axe X-X de celle-ci.In addition, the crank 1 comprises means 13 for locking the second part 7 in its lowered position. These means 13 comprise two locking levers 15 disposed on opposite lateral sides of the crank 1 and received respectively in a obviously 17 formed in the first part 3 of the crank 1 and parallel to the axis XX thereof.
Chaque levier 15 est articulé autour d'un axe 19 sensiblement parallèle à l'axe Y-Y de la pédale 9 dans sa position abaissée. Par conséquent, chaque levier 15 peut pivoter entre une position de verrouillage représentée sur la figure 2 dans laquelle son extrémité de verrouillage 21 est engagée dans une gorge 23 de verrouillage associée ménagée dans la seconde partie 7 de la manivelle 1 , et une position escamotée dans laquelle la seconde partie 7 de la manivelle 1 peut être relevée.Each lever 15 is articulated around an axis 19 substantially parallel to the axis Y-Y of the pedal 9 in its lowered position. Consequently, each lever 15 can pivot between a locking position shown in FIG. 2 in which its locking end 21 is engaged in an associated locking groove 23 formed in the second part 7 of the crank 1, and a retracted position in which the second part 7 of the crank 1 can be raised.
Avantageusement, la gorge 23 de verrouillage possède une section transversale en V pour faciliter l'évacuation des saletés susceptibles de se déposer dans cette gorge 23.Advantageously, the locking groove 23 has a V-shaped cross section to facilitate the evacuation of dirt likely to be deposited in this groove 23.
De plus, la manivelle comprend des moyens 25 de maintien de chaque levier 15 dans sa position de verrouillage. Ces moyens 25 de maintien comprennent des moyens élastiques de rappel des leviers 15 autour de leurs axes 19 d'articulation dans la position de verrouillage. Ces moyens élastiques de rappel comprennent un ressort hélicoïdal de compression logé dans un passage 27 traversant la manivelle et écartant les extrémités 29 des leviers 15 opposées aux extrémités 21 de verrouillage.In addition, the crank comprises means 25 for holding each lever 15 in its locked position. These retaining means 25 comprise elastic means for returning the levers 15 around their axes 19 of articulation in the locked position. These elastic return means comprise a helical compression spring housed in a passage 27 passing through the crank and separating the ends 29 of the levers 15 opposite the locking ends 21.
Pour faciliter l'actionπement des leviers 15, ceux-ci comportent à leurs extrémités 29 respectives un bouton d'actionnement 31.To facilitate the action of the levers 15, these have at their respective ends 29 an actuation button 31.
Par ailleurs, comme on le voit sur les figures 1 et 2, la manivelle comporte en outre des moyens 33 de déplacement automatique de la seconde partie 7 dans sa position relevée.Furthermore, as seen in Figures 1 and 2, the crank further comprises means 33 for automatic displacement of the second part 7 in its raised position.
Ces moyens 33 comprennent un ressort hélicoïdal 35 de torsion entourant l'axe 11 d'articulation et dont les extrémités sont respectivement en liaison d'actionnement, par exemple par fixation ou un simple appui, avec la première 3 et la seconde 7 parties de la manivelle. Le ressort 35 est précontraint de telle manière qu'il relève automatiquement la seconde partie 7 de la manivelle lorsque les deux leviers 15 sont en position escamotéeThese means 33 comprise a helical spring 35 of torsion surrounding the axis 11 of articulation and the ends of which are respectively in actuating connection, for example by fixing or a simple support, with the first 3 and the second 7 parts of the crank. Spring 35 is prestressed so that it automatically raises the second part 7 of the crank when the two levers 15 are in the retracted position
En outre, la première partie 3 de la manivelle 1 comprend à son extrémité en regard de la seconde partie 7, côté pédale, un méplat 37 formant butée pour limiter le mouvement de basculement de la pédale 9 et pour éviter que celle-ci ne heurte la première partie 3 lorsqu'elle est en position relevéeIn addition, the first part 3 of the crank 1 comprises at its end opposite the second part 7, on the pedal side, a flat 37 forming a stop to limit the tilting movement of the pedal 9 and to prevent it from hitting the first part 3 when in the raised position
La manivelle 1 selon l'invention fonctionne de la manière suivante Pour relever la pédale 9, on appuie simultanément sur les deux boutons d'actionnement 31 à encontre de la force exercée par le ressort 25 Ceci permet de dégager les extrémités 21 des leviers 15 des gorges 23 de sorte que par le couple exercé par le ressort 35 sur la seconde partie 7 de la manivelle, celle-ci bascule autour de son axe d'articulation 11 vers la position relevée représentée sur la figure 3 Le méplat formant butée 37 empêche que lors de ce relèvement automatique, la pédale 9 ne heurte la première partie 3 de la manivelle 1The crank 1 according to the invention operates in the following manner To raise the pedal 9, the two actuating buttons 31 are pressed simultaneously against the force exerted by the spring 25 This allows the ends 21 of the levers 15 to be released grooves 23 so that by the torque exerted by the spring 35 on the second part 7 of the crank, the latter rocks about its articulation axis 11 towards the raised position shown in FIG. 3 The flat forming a stop 37 prevents during this automatic raising, the pedal 9 does not strike the first part 3 of the crank 1
Grâce à cette position relevée qui réduit l'encombrement de la bicyclette dû aux pédales, un utilisateur peut ranger une bicyclette équipée d'une manivelle selon l'invention beaucoup plus facilement qu'une bicyclette équipée de manivelles classiques De plus, il n'y a plus de risque qu'il se prenne la pédale 9 dans le tibia quand il pousse sa bicycletteThanks to this raised position which reduces the size of the bicycle due to the pedals, a user can store a bicycle fitted with a crank according to the invention much more easily than a bicycle fitted with conventional cranks. is more likely to take pedal 9 in the shin when he pushes his bicycle
Par ailleurs, la gorge 23 en V présente en outre l'avantage qu'elle permet de libérer la pédale 9 en cas de choc violent sur celle-ci, ce qui évite à l'utilisateur de la bicyclette une chute lorsque la pédale 9 touche par exemple le sol dans un virageFurthermore, the V-shaped groove 23 also has the advantage that it makes it possible to release the pedal 9 in the event of a violent impact thereon, which prevents the user of the bicycle from falling when the pedal 9 touches for example the ground in a bend
Bien entendu pour verrouiller la seconde partie 7 dans sa position abaissée, il suffit d'un seul levier 15 de verrouillage Mais la disposition décrite avec deux leviers 15 présente l'avantage d'assurer une meilleure sécurité, car on empêche un repli intempestif de la pédale 9 causé par exemple par un choc sur un seul des deux leviers 15.Of course, to lock the second part 7 in its lowered position, a single locking lever 15 is sufficient. However, the arrangement described with two levers 15 has the advantage of ensuring better security, because an untimely folding of the pedal 9 is prevented, caused for example by a shock on only one of the two levers 15.
Pour abaisser la pédale 9, on exerce tout simplement une force sur la pédale à encontre de la force exercée par le ressort 35 jusqu'à ce que les extrémités 21 des leviers 15 s'engagent automatiquement, par la pression exercée par le ressort 25 dans les gorges 23.To lower the pedal 9, a force is simply exerted on the pedal against the force exerted by the spring 35 until the ends 21 of the levers 15 engage automatically, by the pressure exerted by the spring 25 in the gorges 23.
On comprend donc que la manivelle selon l'invention permet de réduire l'encombrement d'une bicyclette dû aux pédales.It is therefore understood that the crank according to the invention makes it possible to reduce the size of a bicycle due to the pedals.
La manivelle selon l'invention se distingue par sa simplicité de construction, sa facilité d'usage et son degré de sécurité élevé empêchant un repli intempestif d'une pédale. The crank according to the invention is distinguished by its simplicity of construction, its ease of use and its high degree of security preventing an untimely folding of a pedal.
