DISPOSITIF A ANNEAU DE COMMANDE MANUELLE D'ACCELERATION
POUR VEHICULE A MOTEUR
L'invention concerne un dispositif de commande manuelle d'accélération pour véhicule à moteur comportant un volant de direction et un mécanisme d'accélérateur incluant une pédale d'accélérateur, dispositif comportant un anneau de commande doublant le volant, mobile axialement par rapport au volant, et relié par une channe cinématique au mécanisme d'accélérateur.DEVICE WITH MANUAL ACCELERATION CONTROL RING
FOR MOTOR VEHICLE
The invention relates to a manual acceleration control device for a motor vehicle comprising a steering wheel and an accelerator mechanism including an accelerator pedal, device comprising a control ring doubling the steering wheel, axially movable relative to the steering wheel. , and connected by a kinematic chain to the accelerator mechanism.
Le souci d'adapter la commande des véhicules à moteur aux handicapés des membres inférieurs a conduit depuis longtemps à préconiser l'usage d'un anneau accélérateur doublant le volant à l'avant (cf. par exemple le document FR-A-1 135 356) : le conducteur qui désire accélérer enfonce l'anneau avec les pouces ou l'avant-bras posé en travers du volant. The concern to adapt the control of motor vehicles to the disabled of the lower limbs has long led to advocating the use of an accelerator ring doubling the steering wheel at the front (see for example document FR-A-1 135 356): the driver who wishes to accelerate pushes the ring with his thumbs or forearm placed across the steering wheel.
Cette disposition s'avère présenter un certain nombre d'inconvénients. Ainsi, l'anneau occupant l'avant du volant complique la manoeuvre de celui-ci. Il modifie défavorablement l'esthétique de l'habitacle et signale de manière trop visible aux tiers que le véhicule est celui d'un handicapé. Plus grave encore, la proéminence de l'anneau par rapport au volant entrain des risques élevés de fausses manoeuvres (accélération intempestive). De plus, l'anneau peut s' avérer très dangereux pour le conducteur en cas de chocs, ce qui a conduit à rechercher des dispositifs compliqués d'escamotage de l'anneau (cf. le document FR-A-2 412 437). This arrangement turns out to have a certain number of drawbacks. Thus, the ring occupying the front of the steering wheel complicates the operation thereof. It adversely affects the aesthetics of the passenger compartment and signals too clearly to third parties that the vehicle is that of a disabled person. Even more serious, the prominence of the ring in relation to the steering wheel leads to high risks of false operations (untimely acceleration). In addition, the ring can be very dangerous for the driver in the event of impacts, which has led to the search for complicated devices for retracting the ring (cf. document FR-A-2 412 437).
L'invention vise à proposer un dispositif du type mentionné en tête de ce mémoire, ne présentant pas les inconvénients précités. The invention aims to propose a device of the type mentioned at the head of this thesis, not having the aforementioned drawbacks.
L'invention atteint son but grâce une conception radicalement différente de l'agencement de l'anneau accélérateur, lequel, selon l'invention, est monté derrière le volant. Ainsi, le conducteur agit sans fatigue sur la commande en le tirant avec les quatre derniers doigts de chaque main, au lieu de pousser avec le pouce. L'emplacement de la commande derrière le volant dégage la face avant de celui-ci, ce qui offre au conducteur une plus grande facilité de manoeuvre et assure plus de discrétion et d'esthétique au dispositif. De plus, un conducteur valide peut conduire sans aucune gêne même si la commande manuelle reste en place. Le cas échéant, L'invention permet de placer sur le volant une boule de manoeuvre, ce qu'interdisent les dispositifs connus. The invention achieves its object by means of a radically different design from the arrangement of the accelerator ring, which, according to the invention, is mounted behind the steering wheel. Thus, the driver acts without fatigue on the control by pulling it with the last four fingers of each hand, instead of pushing with the thumb. The location of the control behind the steering wheel clears the front of the steering wheel, which gives the driver greater ease of maneuvering and provides more discretion and aesthetics to the device. In addition, a valid driver can drive without any discomfort even if the manual control remains in place. Where appropriate, the invention makes it possible to place an operating ball on the steering wheel, which is prohibited by known devices.
Selon un aspect particulièrement avantageux de l'invention, la chaîne cinématique reliant l'anneau de commande à la pédale d'accélérateur comporte un élément coulissant dont le coulissement est réalisé par roulement (glissière à galopin à pistes fermées de billes, glissière à chariots à galets, douilles à billes) : il est préférable en effet de prohiber le coulissement par frottement qui risque trop de conduire à des blocages en raison du porte-å-faux quelquefois important de l'effort exercé sur L'anneau par rapport à l'axe de coulissement. According to a particularly advantageous aspect of the invention, the kinematic chain connecting the control ring to the accelerator pedal comprises a sliding element, the sliding of which is carried out by rolling (runner slide with closed tracks of balls, slide with carriages with rollers, ball bushings): it is preferable indeed to prohibit sliding by friction which is too likely to lead to blockages because of the sometimes large overhang of the force exerted on the ring compared to the sliding axis.
L'élément coulissant parallèle à la colonne de direction peut être rattaché au manchon extérieur de ladite colonne de direction, ce qui simplifie l'adaptation, mais on peut aussi prévoir que la - châine cinématique est coaxiale à la colonne de direction. Dans ce dernier cas, on peut facilement rendre l'anneau de commande également mobile en rotation, ce qui permet de tourner le volant en maintenant l'anneau serré en position d'accélération sans glissement entre l'anneau et les doigts, au contraire de la première solution. The sliding element parallel to the steering column can be attached to the outer sleeve of said steering column, which simplifies adaptation, but it can also be provided that the kinematic chain is coaxial with the steering column. In the latter case, it is easy to make the control ring also mobile in rotation, which makes it possible to turn the steering wheel while keeping the ring tight in the acceleration position without sliding between the ring and the fingers, unlike the first solution.
La channe cinématique comporte, outre l'élément coulissant, deux biellettes entraînant une tige de liaison attachées à la pédale d'accélérateur. The kinematic chain comprises, in addition to the sliding element, two rods driving a connecting rod attached to the accelerator pedal.
Avantageusement, l'anneau comporte une fixation amovible 8 la chaîne cinématique et est conformé de manière à pouvoir être retiré en passant autour du volant. Advantageously, the ring has a removable fixing 8 the kinematic chain and is shaped so that it can be removed by passing around the steering wheel.
D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante d'un mode préféré de réalisation. Il sera fait référence aux dessins annexés sur lesquels :

Le véhicule, dont seuls les organes essentiels à ta compréhension de l'invention sont représentés, comprend un volant 1 calé à L'extrémité avant de la colonne de direction 2 qui pivote dans un manchon extérieur 3 solidaire du bâti du véhicule. Le véhicule comporte par ailleurs un mécanisme d'accélération incluant une pédale d'accélérateur 4 articulée de manière classique. The vehicle, of which only the organs essential to your understanding of the invention are represented, comprises a steering wheel 1 wedged at the front end of the steering column 2 which pivots in an outer sleeve 3 secured to the vehicle frame. The vehicle also includes an acceleration mechanism including a conventionally articulated accelerator pedal 4.
SeLon L'invention, un anneau métallique accélérateur 5 de forme et dimensions voisines de celles du volant 1 vient doubler le volant 1 à l'arrière, sensiblement parallèlement audit volant 1 et à une distance maximale permettant au conducteur qui a les mains sur le volant 1 de saisir l'anneau 5 avec les quatre doigts de chaque main pour rapprocher l'anneau 5 du volant 1. According to the invention, a metallic accelerator ring 5 of shape and dimensions close to those of the steering wheel 1 doubles the steering wheel 1 at the rear, substantially parallel to said steering wheel 1 and at a maximum distance allowing the driver who has his hands on the steering wheel 1 take hold of ring 5 with the four fingers of each hand to bring ring 5 closer to the handwheel 1.
L'anneau 5 comporte une corde 6 au milieu de laquelle est fixé un manchon 7 de raccordement amovible à la channe cinématique : une vis papillon 8 peut bloquer dans le manchon 7 l'extrémité 9 de la channe cinématique. The ring 5 comprises a cord 6 in the middle of which is fixed a sleeve 7 for removable connection to the kinematic chain: a butterfly screw 8 can block in the sleeve 7 the end 9 of the kinematic chain.
Cette dernière se compose d'un élément coulissant 10 permettant un guidage linéaire sans jeu. The latter consists of a sliding element 10 allowing linear guidance without play.
Une première extrémité 9 dudit élément est liée à
L'anneau 5 tandis qu'une seconde extrémité 11 forme une articulation 12 pour une biellette 13.A first end 9 of said element is linked to
The ring 5 while a second end 11 forms a hinge 12 for a link 13.
L'élément coulissant 10 est une glissière formee d'une pièce 14 solidaire d'un galopin 15 guidé dans un rail en U 16 grâce à deux pistes à billes coopérant avec les ailes du rail 16. Cette constitution évite tout risque de blocage du coulissement même en cas de porte-à-faux important de L'effort appliqué sur la pièce 14. The sliding element 10 is a slide formed by a piece 14 integral with a cantilever 15 guided in a U-shaped rail 16 by means of two ball tracks cooperating with the wings of the rail 16. This constitution avoids any risk of blocking the sliding. even in the event of a significant overhang of the force applied to the part 14.
L'âme du rail 16 est fixée sur une pièce 18, elle-même rendue solidaire - via une liaison i9 et des moyens de fixation permanents ou amovibles, non représentés - du manchon extérieur 3 de la colonne de direction. The core of the rail 16 is fixed on a part 18, itself made integral - via a connection i9 and permanent or removable fixing means, not shown - of the outer sleeve 3 of the steering column.
La pièce 18 comporte un prolongement arrière formant un pivot 21 pour articuler une biellette coudée 22 au niveau du coude. Une extrémité de la biellette coudée 22 est articulée en 23 sur une extrémité de la biellette 13. The part 18 has a rear extension forming a pivot 21 for articulating a bent rod 22 at the elbow. One end of the angled link 22 is articulated at 23 on one end of the link 13.
L'autre extrémité de la biellette coudée 22 permet l'accrochage articulé en 24 d'une tige de liaison 25 transmettant les mouvements de la biellette 24 à la pédale d'accélérateur 4. The other end of the angled link 22 allows the articulated attachment at 24 of a connecting rod 25 transmitting the movements of the link 24 to the accelerator pedal 4.
Le fonctionnement du dispositif de l'invention est le suivant. Le conducteur qui désire accélérer tire, à L'aide des quatre derniers doigts de la main, l'anneau 5 vers le volant 1, ce qui entrain le coulissement vers l'avant de la pièce 18 par rapport au rail 16, donc le pivotement de la biellette 22 (dans le sens trigonométrique sur la figure 1), et par conséquent l'enfoncement de la pédale d'accélérateur 4. The operation of the device of the invention is as follows. The driver who wishes to accelerate pulls, using the last four fingers of the hand, the ring 5 towards the steering wheel 1, which causes the part 18 to slide forward relative to the rail 16, therefore the pivoting of the link 22 (in the counterclockwise direction in FIG. 1), and consequently depressing the accelerator pedal 4.
Le relâchement de l'anneau 5 entrain des mouvements inversés sous l'effet du ressort du mécanisme de la pédale d'accélérateur.The release of the ring 5 causes reverse movements under the effect of the spring of the accelerator pedal mechanism.
Sur la figure 4, on a représenté en traits pleins le volant 1 et en pointillés l'anneau 5. La forme et les dimensions de celui-ci sont voisines de celles du volant de manière à permettre l'accès à l'anneau depuis n'importe quelle position des mains sur le volant. Par ailleurs, l'anneau 5 doit être compatible avec les commandes éventuellement situées derriére le volant (lumières, clignotants, avertisseurs, etc.). In FIG. 4, the flywheel 1 is shown in solid lines and the ring 5 in dotted lines. The shape and the dimensions thereof are close to those of the flywheel so as to allow access to the ring from n any position of the hands on the steering wheel. Furthermore, the ring 5 must be compatible with the controls, if any, located behind the steering wheel (lights, turn signals, horns, etc.).
Enfin, pour permettre le démontage de l'anneau 5 sans avoir à démonter le volant 1, il convient qu'au moins une dimension intérieure de l'anneau 5 (par exemple la dimension D sur la figure 4) soit supérieure au diamètre du volant. Pour répondre à ces impératifs, l'anneau peut avoir, comme représenté, une forme non rigoureusement circulaire. Finally, to allow the disassembly of the ring 5 without having to disassemble the flywheel 1, at least one interior dimension of the ring 5 (for example the dimension D in FIG. 4) should be greater than the diameter of the flywheel . To meet these requirements, the ring may have, as shown, a shape that is not strictly circular.
