Description

CHÂSSIS A DEFORMATION CONTROLEE POUR UN ENGIN DE GLISSE, NOTAMMENT POUR UNE PLANCHE A ROULETTES CHASSIS WITH CONTROLLED DEFORMATION FOR A SLIDING MACHINE, PARTICULARLY FOR A SKATEBOARD
La présente invention concerne un châssis à déformation contrôlée pour un engin de glisse, notamment pour une planche à roulettes.The present invention relates to a chassis with controlled deformation for a gliding device, in particular for a skateboard.
Une planche à roulettes de base est constituée d'une platine dite aussi plateau, présentant une souplesse donnée et de deux arbres équipés à leurs extrémités de roues montées libres en rotation, lesdites roues portant des bandages pleins généralement en élastomère, de qualité adaptée aux évolutions recherchées.A basic skateboard is made up of a plate also known as a plate, having a given flexibility and two shafts equipped at their ends with wheels mounted free in rotation, said wheels carrying solid tires generally made of elastomer, of quality adapted to developments. sought.
Les arbres sont solidarisés chacun à un support rapporté sur un bloc en matériau élastomère. Ce bloc a des capacités de déformation proportionnelles notamment à la raideur de l'élastomere et cette capacité de déformation autorise des orientations de l'arbre par rapport à l'axe longitudinal de la planche.The trees are each secured to a support attached to a block of elastomeric material. This block has deformation capacities proportional in particular to the stiffness of the elastomer and this deformation capacity allows orientations of the shaft relative to the longitudinal axis of the board.
L'utilisateur, par sa position sur la platine fait porter son poids transversalement, d'un côté ou de l'autre, en sorte d'obtenir la déformation voulue du bloc et l'orientation recherchée des axes de roues. La planche à roulettes peut être ainsi pilotée par la position de l'utilisateur. Néanmoins, l'angle d'orientation reste faible et le rayon de braquage est grand.The user, by its position on the plate, carries its weight transversely, on one side or the other, so as to obtain the desired deformation of the block and the desired orientation of the wheel axles. The skateboard can thus be controlled by the position of the user. However, the orientation angle remains small and the turning radius is large.
Un tel véhicule reste peu maniable surtout lorsque la planche est de grande longueur dite "longboard" or il serait utile de pouvoir prendre des virages serrés.Such a vehicle remains difficult to handle, especially when the board is of great length known as a "longboard", but it would be useful to be able to take tight turns.
Dans la cas particulier d'un engin à bandages pneumatiques et éventuellement propulsé, la demande de brevet français N°2 784 302 décrit un agencement avec un parallélogramme déformable qui accentue l'effet de braquage et surtout qui permet une inclinaison des roues. Un tel agencement, en plus d'être mécaniquement complexe, est incompatible avec une planche à roulettes ayant une garde au sol faible comme il se doit pour faciliter la montée et assurer un parfait équilibre en laissant le centre de gravité le plus bas possible. De plus, le contrôle de la déformation du parallélogramme reste un problème non résolu dans cette demande de brevet.In the particular case of a vehicle with pneumatic tires and possibly propelled, French patent application No. 2,784,302 describes an arrangement with a deformable parallelogram which accentuates the turning effect and above all which allows an inclination of the wheels. Such an arrangement, in addition to being mechanically complex, is incompatible with a skateboard having a low ground clearance as it should to facilitate the climb and ensure a perfect balance by leaving the center of gravity as low as possible. In addition, the control of the deformation of the parallelogram remains an unsolved problem in this patent application.
Ce montage à parallélogramme déformable reste réservé à des engins de grandes dimensions, avec une garde au sol élevée et des roues avec pneumatique.This deformable parallelogram mounting remains reserved for large-sized vehicles, with high ground clearance and wheels with pneumatic tires.
Le brevet US-A-5 540 455 propose un perfectionnement pour améliorer grandement les capacités de braquage. En effet, ce brevet propose de réaliser une platine avec deux plates-formes articulées l'une par rapport à l'autre. L'utilisateur pose alors un pied sur chaque plate-forme et peut orienter chacune d'elle comme il le souhaite. Un ressort est interposé pour constituer cette articulation.US-A-5,540,455 proposes an improvement to greatly improve the turning capacities. Indeed, this patent proposes to produce a plate with two platforms articulated with respect to each other. The user then places one foot on each platform and can orient each of them as desired. A spring is interposed to constitute this articulation.
Ceci permet d'augmenter le nombre de combinaisons d'orientations des arbres mais on comprend aussi que la conduite d'une telle structure est délicate car les orientations des deux arbres peuvent se trouver opposées, ce qui engendre des mouvements radicaux voire dangereux. De plus, les deux parties peuvent s'incliner dans le sens longitudinal également formant un V dans l'axe d'avancement, ce qui n'est pas satisfaisant.This makes it possible to increase the number of combinations of orientation of the trees but it is also understood that the conduct of such a structure is delicate because the orientations of the two trees can be opposite, which generates radical or even dangerous movements. In addition, the two parts can tilt in the longitudinal direction also forming a V in the advancement axis, which is not satisfactory.
La demande de brevet européen N °933 1 03 décrit un agencement à bras oscillants montés sur une platine pivotante. Si un tel agencement peut procurer un certain confort par rapport au revêtement sur lequel évolue la planche à roulettes, il ne répond pas au problème du braquage tout en ayant une parfaite maîtrise de ce braquage. De plus, la complexité d'une telle réalisation rend un tel agencement incompatible avec le marché ou réservé à une élite. La présente invention vise un châssis à déformation contrôlée pour un engin de glisse, notamment pour une planche à roulettes qui est maîtrisable dans son pilotage, qui est sensible à la répartition des poids transversalement mais aussi longitudinalement, qui est d'une réalisation compatible avec la production industrielle, qui est d'un entretien simplifié et d'une fiabilité totale puisqu'il s'agit d'éléments de structure et non d'éléments mobiles mécaniques rapportés. Selon un autre objectif, le châssis à déformation contrôlée de l'invention améliore le braquage en le rendant notamment plus progressif.European patent application No. 933 1 03 describes an arrangement with oscillating arms mounted on a pivoting plate. If such an arrangement can provide a certain comfort with respect to the coating on which the skateboard operates, it does not respond to the problem of turning while having perfect control of this turning. In addition, the complexity of such an implementation makes such an arrangement incompatible with the market or reserved for an elite. The present invention relates to a chassis with controlled deformation for a gliding apparatus, in particular for a skateboard which is controllable in its steering, which is sensitive to the distribution of the weights transversely. but also longitudinally, which is of an embodiment compatible with industrial production, which is of a simplified maintenance and of total reliability since they are structural elements and not attached mechanical moving elements. According to another objective, the chassis with controlled deformation of the invention improves the steering by making it in particular more progressive.
Selon un autre objectif, le châssis à déformation contrôlée de l'invention peut être adapté et ajusté en fonction de l'utilisateur par quelques modifications simples. L'invention est maintenant décrite en détail en regard des dessins annexés qui représentent un mode de réalisation particulier et préférentiel mais non limitatif, les différentes figures montrent :According to another objective, the controlled deformation chassis of the invention can be adapted and adjusted according to the user by a few simple modifications.

The present invention is now described in its structure with reference to FIGS. 1 to 3.
Le châssis comprend une structure 10 avec une platine centrale 1 2, une platine avant 1 4 et une platine arrière 1 6, toutes les deux solidaires de la platine centrale. Ces platines comportent un agencement en caisson avec un intrados 1 2-1 , 1 4-1 et 1 6-1 et un extrados 1 2-2, 14-2 et 1 6-2. Les termes intrados et extrados se rapportent dans la présente demande à une structure soumise à des contraintes mécaniques, par analogie à un pont, l'extrados correspondant à la partie supérieure travaillant en compression et l'intrados à la partie inférieure travaillant en traction. Il est bien entendu que la surface supérieure peut avoir un profil concave, non représenté par les figures. Dans le mode de réalisation préférentiel, chaque platine avant et arrière est composée de deux bras indépendants 14g, 1 4d ; 1 6g, 1 6d portant chacun une roue 1 7 ou patin, montée libre en rotation sur un arbre.The chassis comprises a structure 10 with a central plate 1 2, a front plate 1 4 and a rear plate 1 6, both integral with the central plate. These plates have a box arrangement with a lower surface 1 2-1, 1 4-1 and 1 6-1 and an upper surface 1 2-2, 14-2 and 1 6-2. The terms lower and upper surfaces relate in the present application to a structure subjected to mechanical stresses, by analogy to a bridge, the upper surface corresponding to the upper part working in compression and the lower surface to the lower part working in traction. It is understood that the upper surface may have a concave profile, not shown in the figures. In the preferred embodiment, each front and rear plate is composed of two independent arms 14g, 1 4d; 1 6g, 1 6d each carrying a wheel 1 7 or skid, mounted to rotate freely on a shaft.
Chacune des platines avant et arrière est solidarisée à la platine centrale 1 2, en l'occurrence par une entretoise transversale 1 8 et 20, comme un profilé en U, réalisé en matériau composite en sorte de conférer aux ailes de chaque profilé en U des capacités élastiques de rappel dans les deux sens et de former une articulation. Ces entretoises assurent l'espacement entre l'extrados et l'intrados. Ces profilés en U sont les plus simples et les plus usités, disponibles aisément dans le commerce mais toute autre forme en W ou double U ou encore avec des dimensions variables tant transversalement que longitudinalement sont immédiatement applicables en fonction des applications, un tel choix étant à la portée de l'homme de l'art. La fonction essentielle de ces éléments formant entretoise est de permettre une déformation du châssis, notamment un mouvement de flexion dans le plan horizontalEach of the front and rear plates is secured to the central plate 1 2, in this case by a transverse spacer 1 8 and 20, like a U-shaped profile, made of composite material so as to give the wings of each U-shaped profile elastic two-way recall capabilities and to form a joint. These spacers provide the spacing between the upper and lower surfaces. These U-shaped sections are the simplest and most widely used, readily available commercially, but any other W-shape or double U or with variable dimensions both transversely and longitudinally are immediately applicable depending on the applications, such a choice being the scope of those skilled in the art. The essential function of these spacer elements is to allow deformation of the chassis, in particular a bending movement in the horizontal plane.
Ces profilés ont leur base dans le plan de l'intrados. De plus, une des ailes de chaque profilé est solidaire de l'extrados de la platine avant ou arrière et l'autre est solidaire de l'extrados de la partie centrale. Ces profilés en U travaillent donc en flexion, en compression et en traction suivant les mouvements.These profiles have their base in the plane of the lower surface. In addition, one of the wings of each profile is integral with the upper surface of the front or rear plate and the other is integral with the upper surface of the central part. These U-shaped profiles therefore work in bending, compression and traction according to the movements.
Un des éléments les plus importants et essentiel à l'invention est une colonne 22 longitudinale, de préférence en position médiane pour des raisons de symétrie. Cette colonne est disposée dans la platine centrale et présente une grande raideur. Cette colonne est déformable dans le plan horizontal et/ou vertical et reliée aux deux platines avant et arrière. Dans le mode de réalisation, cette colonne relie les entretoises en U, parallèlement à l'extrados 1 2-2 de la partie centrale. Cette colonne travaille en flexion et/ou en compression. Elle assure un rappel élastique face aux déformations engendrées par les mouvements de l'utilisateur. Cette platine centrale est équipée d'au moins une entretoise 24 transversale, identique aux entretoises 1 8 et 20, au dimensionnement près comme cela sera expliqué ultérieurement. Cette entretoise assure aussi l'espacement entre l'extrados et l'intrados. Cette entretoise est représentée en position médiane dans le mode de réalisation mais elle peut être décentrée suivant les effets recherchés.One of the most important and essential elements of the invention is a longitudinal column 22, preferably in the middle position for reasons of symmetry. This column is arranged in the central plate and has a great stiffness. This column is deformable in the horizontal and / or vertical plane and connected to the two front and rear plates. In the mode of embodiment, this column connects the U-shaped spacers, parallel to the upper surface 1 2-2 of the central part. This column works in bending and / or compression. It provides an elastic return to the deformations caused by the movements of the user. This central plate is equipped with at least one transverse spacer 24, identical to the spacers 18 and 20, except for the dimensioning as will be explained later. This spacer also provides the spacing between the upper and lower surfaces. This spacer is shown in the middle position in the embodiment but it can be offset according to the desired effects.
Ainsi l'extrados 1 2-2 de la partie centrale est également réalisé en deux parties liées chacune à une des ailes du profilé en U tandis que la base est liée à l'intrados 1 2-1 .Thus the upper surface 1 2-2 of the central part is also produced in two parts each linked to one of the wings of the U-shaped profile while the base is linked to the lower surface 1 2-1.
Ainsi les deux platines avant et arrière sont articulées par rapport à la partie centrale et cette partie centrale comprend elle-même une articulation médiane.Thus the two front and rear plates are articulated with respect to the central part and this central part itself comprises a central articulation.
Il est en outre prévu des moyens 26 de reprise de la charge verticale qui constituent l'intrados. Ces moyens comprennent au moins un tendon, en l'occurrence deux tendons 28 longitudinaux, tous deux liés aux platines avant et arrière et travaillant en traction et passant sous la platine centrale.Means 26 are also provided for taking up the vertical load which constitute the lower surface. These means comprise at least one tendon, in this case two longitudinal tendons 28, both linked to the front and rear plates and working in traction and passing under the central plate.
Ainsi, pour toute charge exercée sur l'extrados, les tendons travaillent en traction et la colonne 22 longitudinale médiane, en plus de travailler en flexion et d'assurer un rappel élastique dans le plan horizontal, travaille aussi en compression en participant à la reprise des efforts. Comme montré sur la figure 4, l'utilisateur exerce un effort sur le côté droit par rapport au sens F d'avancement. Les deux trains de roues sont orientés de façon symétrique suivant la courbe Ç car l'utilisateur est en position avant/arrière centrée. L'entretoise 24 transversale médiane et la colonne 22 longitudinale médiane travaillent de façon principale. Sur la figure 5, l'utilisateur exerce son effort toujours sur le côté droit par rapport au sens d'avancement, mais en position décentrée longitudinalement sur l'avant. On constate qu'il y a une déformation plus prononcée sur l'avant suivant une courbe ÇJ_ qui conduit à une courbure plus serrée tandis que l'arrière suit une courbe Ç2 à rayon de braquage plus grand.Thus, for any load exerted on the upper surface, the tendons work in traction and the median longitudinal column 22, in addition to working in bending and ensuring an elastic return in the horizontal plane, also works in compression by participating in the recovery some efforts. As shown in Figure 4, the user exerts a force on the right side relative to the direction F of advancement. The two sets of wheels are oriented symmetrically along the curve Ç because the user is in a centered front / rear position. The median transverse spacer 24 and the median longitudinal column 22 work mainly. In FIG. 5, the user exerts his force always on the right side relative to the direction of advance, but in the position longitudinally off center on the front. We notice that there is a more deformation pronounced on the front following a curve ÇJ_ which leads to a tighter curvature while the rear follows a curve Ç2 with a larger turning radius.
En effet, dans ce cas, l'entretoise 24 transversale médiane et la colonneIndeed, in this case, the median transverse spacer 24 and the column
22 longitudinale médiane sont sollicitées de façon principale mais en plus, l'entretoise avant 1 8 est déformée. Ainsi le train avant tourne avec un angle de braquage qui est la somme des deux déformations, ce qui donne cette courbure plus prononcée.22 longitudinal center are stressed mainly but in addition, the front spacer 1 8 is deformed. Thus the front axle turns with a steering angle which is the sum of the two deformations, which gives this more pronounced curvature.
Sur ces figures 4 et 5, on constate la déformation des différentes entretoises dont les ailes se rapprochent pour assurer une déformation angulaire.In these Figures 4 and 5, we see the deformation of the different spacers whose wings come together to ensure angular deformation.
Lors des mouvements à braquage différencié, il se produit un effet de relance car la poussée des appuis de l'utilisateur, en plus de la force centrifuge, provoque une action motrice.During movements with differentiated steering, there is a revival effect because the thrust of the user's supports, in addition to the centrifugal force, causes a motor action.
On note aussi que dans cet agencement selon la présente invention, le châssis est particulièrement stable quelle que soit la vitesse. En effet, cette double déformation n'est pas soumise aux effets de vitesse et on n'enregistre aucun effet d'instabilité à haute vitesse.It should also be noted that in this arrangement according to the present invention, the chassis is particularly stable whatever the speed. Indeed, this double deformation is not subject to the effects of speed and no effect of instability at high speed is recorded.
Dans les montages à essieu sur bloc élastomère soit le réglage est dur et l'engin est plus stable à grande vitesse mais peu maniable ou le réglage est souple pour être maniable et l'engin devient vite instable dès que la vitesse augmente.In axle assemblies on an elastomer block, either the adjustment is hard and the machine is more stable at high speed but not very easy to handle or the adjustment is flexible to be easy to handle and the machine quickly becomes unstable as soon as the speed increases.
Pour le châssis de la présente invention, on peut ajuster l'effort de rappel élastique des ailes des entretoises car la forme en LJ permet d'y introduire un pain de mousse élastomère par exemple. La densité de cette mousse élastomère et sa structure interne à cellules ouvertes ou fermées autorisent des réglages fins en fonction du poids de l'utilisateur notamment.For the chassis of the present invention, it is possible to adjust the elastic return force of the wings of the spacers because the LJ shape makes it possible to introduce an elastomeric foam bar, for example. The density of this elastomeric foam and its internal structure with open or closed cells allow fine adjustments depending on the weight of the user in particular.
En variante, on peut prévoir aussi d'autres éléments élastiques de rappel tels que des ressorts ou des lames flexibles.Alternatively, it is also possible to provide other elastic return elements such as springs or flexible blades.
Il est aussi possible de prévoir des moyens 30 de bridage de la colonne, réglables, en sorte de durcir plus ou moins la réactivité de cette colonne. Ainsi de tels moyens peuvent comprendre un câble noyé avec un système de tendeurs. De même, sur la figure 6, on constate que la reprise du poids de l'utilisateur est réalisée par les tendons dont la capacité de rappel élastique permet également un réglage de la souplesse à la charge, constituée du poids de l'utilisateur et des effets dynamiques. Lorsque l'utilisateur se place d'un seul côté, le déséquilibre latéral provoque un braquage d'autant plus important que les appuis sont proches du milieu de la planche. Ainsi l'utilisateur peut contrôler la maniabilité et la stabilité du châssis par déplacement des appuis.It is also possible to provide means 30 for clamping the column, adjustable, so as to more or less harden the reactivity of this column. Thus such means may include a cable embedded with a system of tensioners. Similarly, in FIG. 6, it can be seen that the recovery of the weight of the user is carried out by the tendons, the elastic return capacity of which also allows the flexibility of the load to be adjusted, consisting of the weight of the user and the dynamic effects. When the user stands on one side only, the lateral imbalance causes a turning which is all the more important as the supports are close to the middle of the board. Thus the user can control the handling and stability of the chassis by moving the supports.
Les modes de réalisation présentés l'ont été de façon simplifiée avec des entretoises en faible nombre mais, en fonction des besoins et des calculs, il est aussi possible de multiplier ces entretoises en sorte de réaliser une colonne vertébrale du type "arête de poisson" .The embodiments presented have been presented in a simplified manner with spacers in small number but, according to needs and calculations, it is also possible to multiply these spacers so as to produce a spine of the "fishbone" type. .
Il est important de noter que le châssis à déformation contrôlée de l'invention comprend une partie avant et une partie arrière reliées par l'intermédiaire d'une partie centrale, l'ensemble formant une structure en caisson avec un moment d'inertie dans le plan longitudinal médian vertical relativement important de manière à reprendre notamment l'effort exercé par le poids de l'utilisateur, ladite structure offrant une moindre résistance pour permettre des déformations par flexion dans le plan horizontal. Cet agencement permet lors du déplacement de la charge d'induire une déformation de la structure permettant le braquage, comme représenté par exemple par les figures 4 et 5.It is important to note that the controlled deformation chassis of the invention comprises a front part and a rear part connected via a central part, the whole forming a box structure with a moment of inertia in the relatively large vertical median longitudinal plane so as to in particular take up the force exerted by the weight of the user, said structure offering less resistance to allow deformations by bending in the horizontal plane. This arrangement makes it possible, during the displacement of the load, to induce a deformation of the structure allowing the turning, as shown for example by FIGS. 4 and 5.
A titre d'exemple, la partie centrale peut être réalisée en un bloc de matériau expansible, en mousse par exemple, avec des propriétés non uniformes de manière à obtenir la structure en caisson précisée ci-dessus.By way of example, the central part can be made of a block of expandable material, in foam for example, with non-uniform properties so as to obtain the box structure specified above.
Selon un autre mode de réalisation, la partie centrale peut comprendre un plateau rigide relié respectivement à la partie avant et à la partie arrière par un élément, notamment une colonne disposée dans le plan médian longitudinal, de manière à obtenir la structure en caisson précisée ci-dessus. Selon un autre mode de réalisation, la partie centrale peut comprendre deux plateaux reliés d'une manière rigide l'un à la partie avant et l'autre à la partie arrière, les deux plateaux étant reliés par un élément, notamment une colonne disposée dans le plan médian longitudinal, de manière à obtenir la structure en caisson précisée ci-dessus.According to another embodiment, the central part may comprise a rigid plate connected respectively to the front part and to the rear part by an element, in particular a column arranged in the longitudinal median plane, so as to obtain the box structure specified above. -above. According to another embodiment, the central part can comprise two plates rigidly connected, one to the front part and the other to the rear part, the two plates being connected by an element, in particular a column arranged in the longitudinal median plane, so as to obtain the box structure specified above.
Selon un autre mode de réalisation, la partie centrale peut comprendre une forme en caisson avec des éléments raidisseurs croisés disposés au niveau des diagonales, de manière à obtenir la structure en caisson précisée ci- dessus.According to another embodiment, the central part can comprise a box shape with crossed stiffening elements arranged at the diagonals, so as to obtain the box structure specified above.
Pour l'ensemble des variantes, la présence d'au moins un tendon longitudinal, travaillant en traction, reliant les parties avant et arrière, disposé au niveau de l'intrados est nécessaire. Dans les agencements qui découlent du mode de réalisation principal, on peut citer une planche à roulettes avec trois roues au lieu de quatre puisque cela suffit pour la stabilité et on retire encore les bénéfices de la structure présentée ci-avant.For all variants, the presence of at least one longitudinal tendon, working in traction, connecting the front and rear parts, arranged at the lower surface is necessary. In the arrangements which follow from the main embodiment, there may be mentioned a skateboard with three wheels instead of four since this is sufficient for stability and the benefits of the structure presented above are still derived.
On note dans le dispositif décrit au principal que les roues, montées sur des bras oscillants permettent la mise en place d'au moins un élément de freinage ou au moins de ralentissement sur un train de roues. Le diamètre plus important permet d'envisager des fabrications industrielles en recourant à des techniques éprouvées et simples donc d'un prix de revient des produits intéressants, en adaptant par exemple des techniques de fabrication de roues de vélo ou de chariot. It is noted in the device described in the main that the wheels, mounted on oscillating arms allow the establishment of at least one braking element or at least deceleration on a set of wheels. The larger diameter makes it possible to envisage industrial manufacturing by resorting to tried and tested simple techniques therefore of a cost price of the interesting products, by adapting for example techniques of manufacturing of wheels of bicycle or trolley.
