Abstract

The device has wheel axles or wheels that are in pivot connections at ends on a fixed product, where the wheels have a large diameter. The wheels or wheel axles are connected together by an elastic sub-assembly that permits to synchronize and invert rotational movements. The sub-assembly is constituted by two rods that are placed inside a spring which provides annular linear connections and elastic connections and undergoes extension and displacement (K). The axles are symmetric and placed inside rotation axes of two similar supports that are fixed to the skateboard.

Description

2891469 -1-2891469 -1-

1 La présente invention concerne un système de guidage pour une planche à roulettes ou tout autre produit. Les planches à roulettes traditionnelles ont un dispositif de guidage qui limite le diamètre des roues par son architecture. En effet, le système rapproche les roues de la planche ce qui limite l'amplitude et ne permet pas de se pencher beaucoup dans les virages. De plus le petit diamètre des roues provoque une qualité de roulage très moyen. La planche se bloque à chaque déformation du sol et il faut très régulièrement redonner des impulsions avec le pied pour redonner de la vitesse à la planche. Lors de la phase de virage, c'est bien le déplacement du poids de l'utilisateur sur les cotés qui donne la direction aux roues, mais il n'y a pas de sensation de déséquilibre qui procure le plaisir.  The present invention relates to a guidance system for a skateboard or any other product. Traditional skateboards have a guiding device that limits the diameter of the wheels by its architecture. Indeed, the system brings the wheels closer to the board which limits the amplitude and does not allow to bend much in turns. In addition, the small diameter of the wheels causes a very average running quality. The board hangs at each deformation of the ground and it is necessary very regularly to give impulses with the foot to restore speed to the board. During the turn phase, it is the user's weight displacement on the sides that gives the direction to the wheels, but there is no feeling of imbalance that gives pleasure.

Le dispositif selon l'invention permet donc de placer des roues de grands diamètres à une planche pour ainsi augmenter la qualité de roulage. De plus ce système permet aussi de mieux tourner et de procurer plus de plaisir à l'utilisateur. C'est toujours le déplacement du poids de l'utilisateur qui provoque le basculement de la planche et donc la rotation du système de guidage. Plus on se penche et plus cette planche à roulettes inscrit un rayon de virage petit. Ce dispositif permet aussi de régler facilement la réaction de la rotation des roues et donc de l'adapter à chaque utilisateur, en fonction de son poids et de ses goûts.  The device according to the invention therefore makes it possible to place large diameter wheels on a board to thereby increase the rolling quality. Moreover, this system also makes it possible to better rotate and to provide more pleasure to the user. It is always the displacement of the weight of the user that causes the board to tilt and therefore the rotation of the guidance system. The more you look, the more this skateboard inscribes a small turning radius. This device also makes it possible to easily adjust the reaction of the rotation of the wheels and thus to adapt it to each user, according to his weight and his tastes.

Selon les modes particuliers de réalisation: - 2 pièces similaires qui doivent chacune être pourvue d'une roue ou d'un essieu de roues. Un axe de rotation assuré par une liaison pivot et qui sera déporté et perpendiculaire de l'axe de l'essieu ou de la roue. Enfin une liaison pivot qui sera du même coté que l'axe de l'essieu et parallèle pour accueillir le sous-ensemble qui permet de synchroniser le mouvement de rotation de ces 2 pièces. A noter que la distance du déport entre l'axe de rotation de la pièce et l'axe de la roue ou de l'essieu influe sur le comportement car fait varier la force exercée par le sol. La largeur des essieux influe aussi sur le comportement. Cette largeur doit 2891469 -2- 1 permettre une stabilité lors de la prise de vitesse et un déséquilibre lors des virages. Voir Schéma n 2 en annexe. Légende: A: Axe de liaison pivot B: Axe déporté pour la roue ou l'essieu C: Axe liaison pivot avec sous ensemble.  According to particular embodiments: - 2 similar parts which must each be provided with a wheel or a wheel axle. An axis of rotation provided by a pivot connection and which will be offset and perpendicular to the axis of the axle or the wheel. Finally a pivot connection which will be on the same side as the axis of the axle and parallel to accommodate the subassembly that synchronizes the rotational movement of these two parts. Note that the distance of the offset between the axis of rotation of the part and the axis of the wheel or the axle influences the behavior because varies the force exerted by the ground. The width of the axles also influences the behavior. This width must 2891469 -2- 1 allow stability when taking speed and imbalance during turns. See Figure 2 in the appendix. Legend: A: Pivot Link Axle B: Offset Axis for Wheel or Axle C: Pivot Link Axis with Subassembly.

- 1 sous ensemble qui est composé d'un logement pour une liaison pivot à chacune des 2 extrémités pour se monter sur chacune des 2 pièces précédemment citées. Ce sous ensemble devra assurer une liaison linéaire annulaire afin de lier les 2 rotations des 2 pièces précédentes et devra aussi posséder une liaison élastique entre ces 2 extrémités afin de permettre une déformation et de ramener le dispositif à son état initial. Cette liaison élastique devra avoir une force de rabattement réglable afin de tirer plus ou moins fort. Cette liaison élastique permet de lutter contre la force du sol et de composer avec les 2 rotations des liaisons pivots (voir définition des supports, point suivant). Enfin ce sous ensemble doit pouvoir s'adapter à une légère variation de longueur. Voir schéma n 3 en annexe: 6: Les tiges sont fabriquées dans du rond. Elles sont symétriques et disposent de plusieurs perçages pour les réglages en tension du ressort 10: Les liaisons linéaires annulaires ainsi que la liaison élastique sont assurées par un ressort dans lequel les 2 tiges viennent se loger de chaque coté à l'intérieur. Ce ressort à la particularité d'avoir ses 2 anses tangentes aux spires 11: 2 petits pions servent à maintenir le ressort en tension. Un sur chaque tige D: Perçage pour liaison pivot avec les 2 pièces en rotation E: Il est utile de laisser un peu de place derrière les perçages pour renforcer la résistance aux efforts de rotation transmis.  - 1 subassembly which consists of a housing for a pivot connection at each of the two ends to be mounted on each of the two parts mentioned above. This subassembly will have to provide an annular linear connection in order to link the two rotations of the two preceding parts and will also have to have an elastic connection between these two ends in order to allow a deformation and to bring the device back to its initial state. This elastic connection must have an adjustable folding force to pull more or less strong. This elastic connection makes it possible to fight against the force of the ground and to compose with the 2 rotations of the pivotal links (see definition of the supports, next point). Finally this subset must be able to adapt to a slight variation in length. See Figure 3 in Appendix: 6: The rods are made of round. They are symmetrical and have several holes for the tension settings of the spring 10: The annular linear connections and the elastic connection are provided by a spring in which the two rods are housed on each side inside. This spring has the particularity of having 2 handles tangent to turns 11: 2 small pins are used to maintain the spring tension. One on each rod D: Drilling for pivot connection with the 2 rotating parts E: It is useful to leave a little space behind the holes to reinforce the resistance to the transmitted rotational forces.

2 supports similaires qui se montent contre l'élément rigide par plusieurs points de fixation. Ces 2 supports doivent accueillir la liaison pivot réalisée avec les 2 pièces de rotation. L'axe qui permet cette liaison pivot peut avoir un angle qui varie car cette caractéristique influe sur le comportement de la rotation des pièces. Cet angle et les supports sont fixés de telle sorte que les axes des deux liaisons pivot se croisent. Plus le croisement de ces axes est 2891469 -3- 1 proche de l'élément rigide et plus la rotation est rapide et inversement. Plus le croisement est éloigné, plus la rotation sera tardive et brutale. La variation de cet angle peut être réalisé par ce support ou l'ajout de cales entre le support et l'élément rigide. Voir schéma n 4 en annexe: F: 4 points de fixation à la planche sont prévus G: L'axe de la liaison pivot peut être réglable pour modifier la réaction H: Des nervures peuvent être prévues pour renforcer l'arbre- I: Arbre pour assurer la liaison pivot avec la pièce qui tourne et qui tient la roue ou l'essieu.  2 similar supports which are mounted against the rigid element by several fixing points. These 2 supports must accommodate the pivot connection made with the 2 rotating parts. The axis that allows this pivot connection can have a varying angle because this characteristic affects the behavior of the rotation of the parts. This angle and the supports are fixed so that the axes of the two pivot links intersect. The closer the crossing of these axes 2891469 -3- 1 is close to the rigid element and the faster the rotation is and vice versa. The further the crossing is, the more the rotation will be late and brutal. The variation of this angle can be achieved by this support or the addition of wedges between the support and the rigid element. See diagram n 4 in the appendix: F: 4 fixing points to the board are provided G: The axis of the pivot connection can be adjustable to modify the reaction H: Ribs can be provided to strengthen the shaft- I: Tree to ensure the pivot connection with the rotating part which holds the wheel or the axle.

En référence à ces dessins, le dispositif comporte plusieurs éléments illustrés dans le schéma n 1 en annexe: 1: Planche 2: Support 3: Truck 4: Roulements à billes de direction -- 5: Roue 6: Tige 7: Ecrou M8 8: Rondelle 13 x 23 9: Ecrou M 12 10: Ressort 11: Maintien ressort 12: Vis M6 13: Ecrou M6 14: Vis tête fraisée 15: Ecrou M4. A noter que les 2 pièces n 3 nommées truck sont les pièces en rotation qui comportent des roues ou essieux.  With reference to these drawings, the device comprises several elements illustrated in diagram No. 1 in the appendix: 1: Plate 2: Support 3: Truck 4: Steering ball bearings - 5: Wheel 6: Rod 7: Nut M8 8: Washer 13 x 23 9: Nut M 12 10: Spring 11: Hold spring 12: Screw M6 13: Nut M6 14: Countersunk screw 15: Nut M4. Note that the 2 pieces n 3 named truck are the rotating parts that have wheels or axles.

En dynamique, les différents efforts et les réactions de l'ensemble vont être détaillés. La liaison entre les pièces qui tournent et le sol est donc assurée par une ou plusieurs roues. Lorsque l'utilisateur va mettre son poids sur un coté de l'élément rigide, ce guidage va permettre d'inscrire cet élément rigide dans une trajectoire allant sur le même coté. Le sol va exercer un effort sur les 2 pièces en rotation qui vont tourner en sens inverse l'une par rapport à l'autre. Ce mouvement sera synchronisé et contenu par le sous ensemble qui lie les deux pièces. Plus l'élément rigide sera penché sur un coté et plus le rayon du virage sera petit. Voir schéma n 5 en annexe: J: Rotation que l'effort entraîne K: Extension et déplacement du ressort L: Sens de marche M: Effort du sol.  In dynamics, the different efforts and the reactions of the whole will be detailed. The connection between the parts that rotate and the ground is thus provided by one or more wheels. When the user will put his weight on one side of the rigid element, this guidance will allow to register this rigid element in a path on the same side. The soil will exert a force on the 2 rotating parts that will turn in opposite directions relative to each other. This movement will be synchronized and contained by the subassembly that links the two pieces. The more the rigid element is leaning on one side, the smaller the radius of the turn will be. See diagram 5 in the appendix: J: Rotation that the force causes K: Extension and movement of the spring L: Direction of travel M: Effort of the ground.

1 Le montage de ce système débute par la fixation des 2 supports sur l'élément rigide, la planche. Les arbres qui vont accueillir les liaisons pivots doivent avoir leurs axes qui se croisent (parallèles au maximum). Ces deux axes doivent aussi être colinéaires et sur un plan perpendiculaire aux axes des essieux. Si la liaison pivot est assurée par des roulements, l'arbre peut avoir un épaulement qui servira à une portée dé roulement et il pourra aussi avoir l'extrémité filetée afin de fixer en translation la pièce en rotation. Pour une meilleure stabilité lors du roulage il est important de placer les supports suffisamment éloignés. Ensuite il faut monter les 2 pièces sur les 2 supports grâce à des roulements par exemple. Placer les essieux en symétrie et à l'intérieur des axes de rotation des 2 pièces. Ensuite on place en liaison pivot une tige sur chacune des pièces tournantes et ces tiges seront maintenues grâce à une vis/écrou. Ne pas trop serrer car il faut que ces tiges soient en liaison pivot. Enfin loger les 2 tiges à l'intérieur d'un même ressort. Fixer une extrémité de ce ressort sur une des tiges par un pion. Ensuite mettre le ressort en tension en tirant dessus. Une fois la tension voulue atteinte, fixer la seconde extrémité du ressort à la seconde tige grâce à un autre pion.  1 The assembly of this system begins with the fixing of 2 supports on the rigid element, the board. The trees that will host the pivot links must have their intersecting axes (parallel to the maximum). These two axes must also be collinear and on a plane perpendicular to the axes of the axles. If the pivot connection is provided by bearings, the shaft may have a shoulder which will serve a bearing range and it may also have the threaded end to fix in translation the rotating part. For better stability when driving it is important to place the supports far enough apart. Then it is necessary to mount the 2 parts on the 2 supports thanks to bearings for example. Place the axles in symmetry and inside the axes of rotation of the two parts. Then is placed in pivot connection a rod on each of the rotating parts and these rods will be maintained through a screw / nut. Do not over tighten because it is necessary that these rods are in pivot connection. Finally house the 2 rods inside the same spring. Fix one end of this spring on one of the rods by a piece. Then put the spring in tension by pulling on it. Once the desired tension is reached, attach the second end of the spring to the second rod with another peg.

A titre d'exemple non restrictif, les roues pourront faire un diamètre de 80 mm et le déport entre l'axe de l'essieu et l'axe de 25 rotation par rapport à l'élément fixe, peut être de 45 mm.  By way of non-restrictive example, the wheels may have a diameter of 80 mm and the offset between the axis of the axle and the axis of rotation relative to the fixed element, may be 45 mm.
