Abstract

The system creates a link between fixed (18) and mobile (17) part of the suspension. A support (1) is carrying two arms (4,5) each with a pad (6) which can actuate a spring (10) to clamp a plate (9) when the command (13) is activated.

Description

La présente invention concerne un dispositif adaptatif ayant pour but d'augmenter le rendement de pédalage d'un cycliste avec une bicyclette<B>à</B> suspension utilisée en tout terrain. The present invention relates to an adaptive device for the purpose of increasing the pedaling performance of a cyclist with a bicycle <B> to </ B> suspension used in any terrain.

Le phénomène dit "de pompage" qui existe sur les vélos<B>à</B> suspension, est<B>dû à</B> des ocsillations parasites de la suspension provoquées par le pédalage qui gaspillent l'énergie dépensée par le cycliste et nuisent au rendement. Le réglage des fourches<B>à</B> suspension est communément effectué <B>à</B> partir de mollettes ou vis qui ne permettent pas un réglage en temps réel et dans de grandes proportions. Le réglage appliqué est alors un compromis qui n'optimise pas le rendement. Les conséquences de ce non réglage sont un confort moindre sur les terrains accidentés, ou une perte d'énergie par effet de pompage. The so-called "pumping" phenomenon that exists on suspension bicycles is due to parasitic ocsillations of the suspension caused by pedaling which waste the energy expended by the bicycle. cyclist and affect performance. The setting of the suspension <B> to </ B> forks is commonly done <B> from </ b> from knobs or screws that do not allow real time adjustment in large proportions. The adjustment applied is then a compromise that does not optimize performance. The consequences of this non-adjustment are less comfort on uneven ground, or a loss of energy by pumping effect.

Le dispositif sel<B>'</B> on l'invention permet de remédier<B>à</B> ces inconvénients.<B>Il</B> comporte un moyen permettant sur commande d'établir une liaison momentanée entre la partie fixe et la partie mobile de la suspension de manière<B>à</B> ce que les mouvements naturel d'écrasement et de détente de la suspension<B>dû</B> aux aspérités du chemin et aux coups de pédale du cycliste se transforment en un mouvement directionnel autorisant uniquement l'écrasement de la suspension, et par son mode de fonctionnement diminuer ainsi l'amplitude des mouvements naturels précités.<B>il</B> comporte en effet selon une première caractéristique un support sur lequel sont articulés deux bras possédant chacun un patin permettant<B>à</B> l'aide d'une commande déportée de serrer une platine, mobile. Cette platine est reliée<B>à</B> la partie mobile de la suspension par l'intermédiaire d'un ressort. Le dispositif précédemment décrit peut être fixé sur la plupart des fourches<B>à</B> suspension sans modification du vélo ni risque de détérioration. L'orifice inférieur du tube de direction est utilisé pour immobiliser le support au moyen d'un cylindre expansible. Le trou de fixation du garde boue avant est utilisé pour la fixation du ressort. Ainsi, au départ la suspension n'étant pas précontrainte, la conduite du vélo est souple et confortable avec une bonne tenue de route, les risques de creuvaison par pincement sont diminués. Le cycliste peut lorsqu'il le juge utile en fonction du terrain rencontré, décider de mettre en action le dispositif sans descendre du vélo au moyen d'une commande déportée au guidon.<B>A</B> partir de cet instant, le vélo se rigidifie devient moins confortable mais beaucoup plus performant. Les patins qui sont directionnels autorisent, l'enfoncement de la suspension et entravent sont retour grace <B>à</B> leurs géométrie, leurs souplesse, et au liège utilisé comme matériau de friction. Le ressort reliant la platine<B>à</B> la partie mobile de la suspension se tend automatiquement grâce aux aspérités du terrain et aux coups de pédale du cycliste, il comprime la suspension et les deux forces s'opposent de telle manière qu'un équilibre stable s'installe. Une faible pression sur la suspension correspond<B>à</B> un faible déplacement mais si la pression devient plus forte alors rapidement la suspension devient ferme concentre l'energie dépensée puis la restitue immédiatement. Cette situation est permanente en tout terrain et le phénomène de pompage du fait du faible débattement est par conséquence éliminé. Par ailleurs la suspension étant maintenue comprimée, l'attitude du vélo change le guidon est plus bas et la position du cycliste est meilleure dans les montées. Les différences de poids rencontrés d'un cycliste<B>à</B> l'autre sont compensés automatiquement par le glissement de la platine et n'occasionnent pas de réglage particulier. La majorité des pièces composant le dispositif étant réalisées en alliage léger, le poids du vélo n'augmente que de<B>2.5%</B> environ et son encombrement modéré ne gène en rien la maniabilité. The device salt <B> '</ B> of the invention makes it possible to remedy <B> to </ B> these disadvantages. <B> It </ B> comprises means allowing on command to establish a momentary connection between the fixed part and the moving part of the suspension so <B> to </ B> that the natural movements of crushing and relaxation of the suspension <B> due to the roughness of the road and the strokes of cyclist's pedal become a directional movement allowing only the suspension to be crushed, and by its mode of operation thus reduce the amplitude of the aforementioned natural movements. <B> It </ B> comprises in fact according to a first characteristic a support on which are articulated two arms each having a pad allowing <B> to </ B> using a remote control to tighten a plate, mobile. This plate is connected to the moving part of the suspension by means of a spring. The device described above can be attached to most of the forks <B> to </ B> suspension without modification of the bike or risk of deterioration. The lower hole of the steering tube is used to immobilize the support by means of an expandable cylinder. The fixing hole of the front mudguard is used for fixing the spring. Thus, initially the suspension is not prestressed, the bike is flexible and comfortable with good handling, the risk of cruve by pinching are reduced. The cyclist can, when he deems it useful according to the terrain encountered, decide to activate the device without getting off the bike by means of a remote control on the handlebars. <B> A </ B> From that moment, the bike stiffens becomes less comfortable but much more efficient. Skids that are directional allow, the sinking of the suspension and hinder are back thanks to their geometry, their flexibility, and the cork used as friction material. The spring connecting the plate <B> to </ B> the moving part of the suspension is automatically stretched due to the unevenness of the ground and the pedal stroke of the cyclist, it compresses the suspension and the two forces are opposed in such a way that a stable equilibrium is established. A low pressure on the suspension corresponds to a small displacement, but if the pressure becomes stronger then the suspension quickly becomes concentrated concentrates the energy expended and then restores it immediately. This situation is permanent in any terrain and the pumping phenomenon due to the low deflection is consequently eliminated. In addition, the suspension being kept compressed, the attitude of the bicycle changes the handlebar is lower and the position of the cyclist is better in the climbs. The differences in weight encountered from one <B> to </ B> cyclist are compensated automatically by the sliding of the plate and do not cause any particular adjustment. The majority of parts making up the device being made of light alloy, the weight of the bike increases by only <B> 2.5% </ B> and its moderate size does not interfere with the handling.

Selon des modes particuliers de réalisation: Le ressort peut être réalisé dans une lame d'acier traité, épaisseur 1.5mm, et être capable de s'opposer<B>à</B> la force de détente de la suspension afin de trouver un équilibre stable. According to particular embodiments: The spring can be made in a treated steel blade, 1.5mm thick, and be able to oppose <B> to </ B> the relaxation force of the suspension to find a stable equilibrium.
