Description

Système ergonomique de pédalage, avec dérailleur associé.Ergonomic pedaling system with associated derailleur.
L'invention concerne le cycle, la bicyclette. Une bicyclette classique est entraînée par la force humaine, appliquée sur un jeu de pédales, mettant en rotation un plateau qui entraîne une chaîne.The invention relates to the cycle, the bicycle. A conventional bicycle is driven by human force, applied to a set of pedals, rotating a chainring.
L'effort demandé au cycliste est appliqué, à travers la mécanique de la bicyclette, ce qui implique une notion de rendement énergétique dont les ratios sont connus.The effort required of the cyclist is applied, through the mechanics of the bicycle, which implies a notion of energy efficiency whose ratios are known.
Le dispositif, objet de l'invention, apporte une innovation, par rapport à l'état actuel de la technique, en ceci qu'il augmente le rendement de la bicyclette, tout en abaissant l'effort humain.The device, object of the invention, provides an innovation, compared to the current state of the art, in that it increases the performance of the bicycle, while lowering the human effort.
Le dispositif, objet de l'invention, se constitue d'un système de pédalage, associé à un système de dérailleur, les deux sous-ensembles dont il s'agit étant articulés l'un et l'autre de manière indissociable, ce qui est nouveau et original.The device, object of the invention, consists of a pedaling system, associated with a derailleur system, the two subassemblies in question being articulated one and the other inseparably, which is new and original.
Le système de pédalage dont il s'agit produit un effet surmultiplicateur, d'une part et le dérailleur dont il s'agit, qui lui est associé, évite que la chaîne de la bicyclette ne déraille aléatoirement, à l'occasion de divers mouvements, ou chocs.The pedaling system in question produces an overdrive effect, on the one hand and the derailleur in question, which is associated with it, prevents the bicycle chain from derailing randomly during various movements. , or shocks.
Le dispositif, objet de l'invention, se constitue donc d'un système homogène comportant un pédalier et un. dérailleur, spéciaux, caractérisés comme suit :The device, object of the invention, is therefore a homogeneous system comprising a pedal and a. derailleur, special, characterized as follows:
La partie pédalier :The crank part:
Se constitue de deux manivelles (FIG 1. 1) d'un axe, qui peut être creux, (FIGConsists of two cranks (FIG 1. 1) of an axis, which can be hollow, (FIG
1. 2) inséré en force, par l'intérieur, et maintenu en place, dans une position perpendiculaire à la manivelle droite, par une goupille (FIG 1. 3) et collé à l'aide d'une résine industrielle adéquate. Cet axe vient en butée sur la manivelie (FIG 1. 1) par une collerette de retenue. (FlG i . 9), l'axe supporte la manivelie gauche (FIG 1. 16), au moyen d'un évidement, en général conique et de forme carrée (FIG 1. 18) ladite manivelle étant fixée sur l'axe, au moyen d'un écrou (FIG 1. 17).. La partie pédalier comporte en outre des satellites qui sont intégrés au moyen de supports (FIG 1. 7), ces supports faisant partie intégrante de la manivelle, où ils sont insérés en force, dans leurs logements (FIG 1. 8) et collés, tout comme l'axe.1. 2) inserted in force, from the inside, and held in place perpendicular to the right crank by a pin (FIG 1. 3) and glued with a suitable industrial resin. This axis comes into abutment on the crank (FIG 1. 1) by a retaining flange. (Fig. 1, 9), the shaft supports the left crank (FIG. 1. 16), by means of a recess, generally conical and square (FIG 1. 18) said crank being fixed on the axis, by means of a nut (FIG. 17). The crank portion further comprises satellites which are integrated by means of supports (FIG. 1. 7), these supports forming an integral part of the crank, where they are inserted in force, in their housings (FIG 1. 8) and glued, just like the axis.
Le gros roulement (FlG 1. 15) est inséré dans un logement prévu à cet effet à l'intérieur de la manivelle (FlG 1. 1) lequel roulement reçoit le boîtier support- plateau (FlG 1. 4).The large bearing (FlG 1. 15) is inserted in a housing provided for this purpose inside the crank (FlG 1. 1) which bearing receives the tray-support housing (FlG 1. 4).
Le ou les plateaux (FIG 1. 6) sont fixés à la périphérie du boîtier (FIG 1. 4) en position non pas latérale, mais centrée, sur les « oreilles » (FIG 1. 5) par tout moyen adapté (boulonnage, rivetage, etc.)The tray or trays (FIG. 1, 6) are fixed at the periphery of the casing (FIG. 4) in a position which is not lateral but centered on the "ears" (FIG. 1, 5) by any suitable means (bolting, riveting, etc.)
La partie pédalier comporte aussi un boîtier (FlG 1. 10) central, venant se fixer, par vissage, ou autre moyen similaire, de manière appropriée, dans le cadre du cycle dont il s'agit.The crank portion also comprises a housing (FlG 1.10) central, being fixed, by screwing, or other similar means, appropriately, in the context of the cycle in question.
Le boîtier (FIG 1. 10) est centré sur le cadre, et maintenu en place, au moyen d'un écrou cannelé, (FlG 1. 14).The housing (FIG. 10) is centered on the frame and held in place by a fluted nut (FlG 1. 14).
Les deux petits roulements (FIG 1. 15), de l'axe central sont maintenus en position précise à l'aide d'une entretoise (FlG 1. 13) . Le sous-ensemble constitué des petits roulements et de l'entretoise est maintenu en place sur l'axe central, au moyen de deux écrous (FlG 1. 11 et 12) La partie dérailleur :The two small bearings (FIG. 1-15) of the central axis are held in precise position by means of a spacer (FlG 1. 13). The subassembly consisting of the small bearings and the spacer is held in place on the central axis, by means of two nuts (FlG 1. 11 and 12) The derailleur part:
Se constitue, en premier lieu, d'une « patte » (FIG 2. 1) caractérisée en ceci qu'elle permet au dérailleur de descendre dans une position adéquate, par rapport aux plateaux, que supporte le pédalier.In the first place is constituted by a "tab" (FIG. 2.1), characterized in that it allows the derailleur to descend to a suitable position, relative to the plates, which the pedals support.
Cette « patte » se fixe, en lieu et place du dérailleur classique, (couramment utilisé) sur tout support, pouvant faire partie intégrante du cadre d'un vélo. Elle se caractérise par la présence d'un angle, généralement de l'ordre de 3 à 7°, (FlG 2.2) dans sa demi partie inférieure, ce qui permet au déraideur d'avoir la même courbure que les plateaux.This "leg" is fixed, instead of the conventional derailleur (commonly used) on any support, which can be an integral part of the frame of a bicycle. It is characterized by the presence of an angle, generally of the order of 3 to 7 °, (FlG 2.2) in its half lower part, which allows the déraideur to have the same curvature as the trays.
Le dérailleur sera lui-même fixé sur cette patte, par tout moyen approprié. En second lieu, la partie dérailleur se caractérise par un sous-ensemble, à l'origine issu d'un dérailleur classique, dont les dimensions de la fourchette (FIG 3. 2) ont été raccourcies, pour permettre audit dérailleur de descendre dans Ia position nécessaire à son bon fonctionnement, et par une pièce fonctionnelle, (FlG 3. 1) permettant de maintenir l'écartement de la fourchette (FIG 3. 2), et dont la fonction principale sera de maintenir la chaîne, dans son logement, en toute sécurité. The derailleur will itself be fixed on this leg, by any appropriate means. Secondly, the derailleur part is characterized by a subassembly, originally derived from a conventional derailleur, whose fork dimensions (FIG. 3. 2) have been shortened, to allow said derailleur to descend into the engine. position necessary for its proper functioning, and by a functional part, (FlG 3. 1) to maintain the spacing of the fork (FIG 3. 2), and whose main function will be to maintain the chain, in its housing, safely.
