The advantage of the invention is to be able to execute acrobatic figures to the inspiration of the user without having to set foot on the ground other than for the classic momentum. The user is invited to make "kangaroo" style jumps by resting on the scooter's handlebars, the reception on the articulated board allowing him to retract the board from his high position to his low position which causes the motor movement. . The board is automatically pushed up when the user gives the impetus for a new jump.
PRESENTATION. La trottinette à roue tractée est composé de 2 modules: 1 er module: la trottinette. Ce système est connu par ailleurs et concerne plus particulièrement la trottinette en aluminium équipée de roues de 0100,0125ou 0150mm.Le perçage de 2 trous permet la fixation du kit. PRESENTATION. The towed wheel scooter is composed of 2 modules: 1 st module: the scooter. This system is also known and more particularly relates to the aluminum scooter equipped with wheels of 0100,0125 or 0150mm. The drilling of 2 holes allows the attachment of the kit.
2ème module:le kit d'adaptation du dispositif à roue tractée qui fait l'objet de l'invention. 2nd module: the adaptation kit of the towed wheel device which is the subject of the invention.
Il comporte un ensemble pré-monté suivant la figure 1 et des éléments de fixation soit les vis (2) et (3) et les écrous (4). It comprises a pre-assembled assembly according to Figure 1 and fastening elements are the screws (2) and (3) and the nuts (4).
FONCTIONNEMENT.La trottinette à roue tractée a pour vocation d'être utilisée sur des aires aménagées telles skate parc ou piste de rollers.Le fonctionnement comprend 3 séquences explicitées par les dessins de la fig. 2 et de la fig.3: -A) La prise d'élan classique. En position de repos la planche est en position haute.Le pied d'appui sur la planche escamote progressivement celle-ci de sa position haute (fig. 2)à sa position basse (fig. 3) dès le premier pas d'élan. La planche reste en position basse maintenue par le pied d'appui pour une utilisation classique de la trottinette ou effectuer la séquence suivante -B) L'impulsion. Projeter le poids de son corps vers le haut en prenant appui sur le guidon de la trottinette.Cette impulsion a une amplitude qui dépend de la dextérité de l'utilisateur. La planche (7) est libérée et effectue instantanément son mouvement de rappel par l'action du tendeur (18) entraînant la chaîne (14) et la planche (7) à sa butée haute. La roue libre intégrée sur la roue(8) permet la réinitialisation du système chaîne pignons sans freiner la rotation de la roue. FUNCTIONING.The scooter wheeled vocation is intended to be used on developed areas such skate park or roller skating.The operation includes 3 sequences explained by the drawings of FIG. 2 and fig.3: -A) The classic momentum. In the rest position the board is in the high position.The support foot on the board progressively retracts it from its upper position (Fig. 2) to its lower position (Fig. 3) from the first momentum. The board remains in the low position maintained by the support foot for a conventional use of the scooter or perform the following sequence -B) The impulse. Throw the weight of your body upward by leaning on the handlebars of the scooter. This pulse has an amplitude that depends on the dexterity of the user. The board (7) is released and instantly makes its return movement by the action of the tensioner (18) driving the chain (14) and the board (7) at its high stop. The integrated freewheel on the wheel (8) allows the chain sprocket system to be reset without slowing down the rotation of the wheel.
-C) La réception sur la planche. L'énergie cinétique déployée à réception du saut par le principe de l'action réaction est restituée à la planche. La force dynamique sur la planche entraîne l'escamotage de la planche en position basse (fig. 3).La rapidité du mouvement d'escamotage dépend de la vitesse initiale de la trottinette. La chaîne (14) reliée au support (15) est entraînée dans un déplacement presque linéaire et transmet le mouvement moteur à la roue (8) ce qui permet de maintenir la vitesse plus longtemps sans mettre le pied à terre. L'utilisateur se réceptionne sur la planche en gardant les pieds presque joints et le corps bien en ligne par rapport à l'axe de déplacement de la trottinette. -C) The reception on the board. The kinetic energy deployed upon reception of the jump by the principle of the reaction action is restored to the board. The dynamic force on the board causes the board to retract in the down position (Fig. 3) .The speed of the retraction movement depends on the initial speed of the scooter. The chain (14) connected to the support (15) is driven in an almost linear displacement and transmits the motor movement to the wheel (8) which makes it possible to maintain the speed longer without putting the foot on the ground. The user receives on the board keeping the feet almost joined and the body well in line with the axis of movement of the scooter.
DESCRIPTIFDESCRIPTION
Pour décrire l'ensemble du dispositif suivant la figure 1 il faut associer une trottinette classique sans laquelle le kit de montage n'a pas de fonction propre. To describe the entire device according to Figure 1 must be associated with a classic scooter without which the mounting kit has no own function.
Ainsi sur une trottinette existante (1) et après perçage de deux trous en rapport avec le kit de montage l'utilisateur vient fixer celui-ci par les vis (2) ,(3) et les écrous (4) sur le socle de la trottinette. Tous les éléments décrits sont repérés sur la figure 4. Thus on an existing scooter (1) and after drilling two holes in connection with the mounting kit the user comes to fix it by the screws (2), (3) and the nuts (4) on the base of the scooter. All the elements described are marked in FIG.
Le kit est composé essentiellement d'un cadre (5) qui sert d'ossature et d'articulation pour: -le berceau (6) oscillant qui porte la transmission et la roue motrice (8) -la planche (7) limitée en rotation, sert de réceptacle de saut et entraîne la chaîne (14). Le cadre (5) sur lequel est articulé dans sa partie arrière le berceau (6) par les 2 axes (22) et sur sa partie avant est articulé la planche (7) par les roulements (19) sur l'axe (17). Dans un autre mode de construction le cadre ne serait pas nécessaire avec un socle de la trottinette pourvu de 4 flasques. La trottinette à roue tractée serait alors composée d'un seul module intégrant tout le mécanisme. The kit consists essentially of a frame (5) which serves as frame and articulation for: -the oscillating cradle (6) which carries the transmission and the drive wheel (8) -the board (7) limited in rotation , serves as a jump receptacle and drives the chain (14). The frame (5) on which is articulated in its rear part the cradle (6) by the 2 axes (22) and on its front part is hinged the board (7) by the bearings (19) on the axis (17) . In another mode of construction the frame would not be necessary with a base of the scooter provided with 4 flanges. The towed wheel scooter would then consist of a single module integrating the entire mechanism.
Le berceau (6) en forme d'équerre fixe sert de support à la partie motrice du dispositif à roue tractée. Il est articulé sur l'arrière du cadre (5) par les axes (22) et permet à la roue tractée de rester en contact avec le sol, même inégal,de son propre poids. Dans la partie supérieure du berceau se trouve l'axe (23) sur lequel tourillonne l'arbre (12) qui porte le pignon d'entraînement (13) ainsi que le pignon de pédalier (11) .Dans la partie inférieure du berceau se trouve l'axe (21) sur lequel tourillonne une roue (8) (au moins) solidaire de la roue libre (9).Les axes (21) et (23) servent d'entretoise au berceau et peuvent être complétées par une ou des entretoises indépendantes des axes de rotation pour assurer la rigidité de l'ensemble. The cradle (6) in the form of a fixed bracket serves as support for the driving part of the towed wheel device. It is articulated on the rear of the frame (5) by the axes (22) and allows the towed wheel to remain in contact with the ground, even uneven, its own weight. In the upper part of the cradle is the axis (23) on which the shaft (12) which carries the drive gear (13) and the bottom gear (11) journals. In the lower part of the cradle is finds the axis (21) on which a wheel (8) (at least) integral with the freewheel (9) is journalled. The axes (21) and (23) serve as a spacer for the cradle and can be supplemented by one or spacers independent of the axes of rotation to ensure the rigidity of the assembly.
La planche (7) de forme analogue à celle d'une planche de skate connue par ailleurs est modifiée par l'adjonction d'un support (15) à l'arrière de la planche sur lequel est rivé l'extrémité de la chaîne d'entraînement (14).Les deux flasques(20) déportés en hauteur sont solidaires de la planche (7) à l'extrémité de sa partie avant procurant un mouvement de haut en bas et d'avant en arrière. Le tendeur (18) qui assure le rappel de la chaîne (14) est fixé d'une part à l'extrémité libre de la chaîne (14) et d'autre part à l'extrémité de la planche par le boulon (24). Le débattement de la planche (7) est limitée en rotation: - d'une part en position basse presque horizontale par la tête de vis (3) revêtue de caoutchouc sur laquelle vient buter la planche ou le renfort de planche. The board (7) of a shape similar to that of a skateboard known elsewhere is modified by the addition of a support (15) to the rear of the board on which is riveted the end of the chain of The two vertically offset flanges (20) are integral with the board (7) at the end of its front portion providing upward and downward motion and front to back. The tensioner (18) which ensures the return of the chain (14) is fixed on the one hand to the free end of the chain (14) and on the other hand to the end of the board by the bolt (24) . The movement of the board (7) is limited in rotation: - firstly in a low position almost horizontal by the screw head (3) coated with rubber on which abuts the board or the board reinforcement.
- d'autre part en position haute dans une position telle que l'extrémité du support (15) soit le plus près possible du pignon (13) sans le toucher. Ce réglage est obtenu par une vis (25) qui prend appui sur le cadre (5). - On the other hand in a high position in a position such that the end of the support (15) is as close as possible to the pinion (13) without touching it. This adjustment is obtained by a screw (25) which bears on the frame (5).
L'ensemble chaînes et pignons permet la transmission du mouvement moteur. La chaîne (14) qui est solidaire du support (15) et de la planche (7) se trouve au départ du mouvement dans la position de la fig. 2 (position haute). La chaîne (15) englobe sur une çlemi circonférence le pignon menant (13) solidaire de l'arbre (12) et du pignon mené (11) qui sont entraînés en rotation par le mouvement de haut en bas et d'avant en arrière de la planche (7) jusqu'à la position basse représentée par la fig. 3. La chaîne (10) engrène d'une part sur le pignon (11) et d'autre part sur le pignon de roue libre (9) solidaire de la roue (8) . La partie de la chaîne (14) non soumise à l'effort s'enroule sur la moletté (16) pour suivre une direction parallèle au socle de la trottinette. L'extrémité de la chaîne (14) est reliée au tendeur du type sandow (18) dont le point d'ancrage (24)est situé en dessous et à l'avant de la planche (7). The chains and sprockets assembly allows the transmission of the motor movement. The chain (14) which is secured to the support (15) and the board (7) is at the start of the movement in the position of FIG. 2 (up position). The chain (15) includes on a circumference circumference the driving pinion (13) integral with the shaft (12) and the driven pinion (11) which are driven in rotation by the movement up and down and back and forth of the board (7) to the low position shown in FIG. 3. The chain (10) meshes with the pinion (11) and with the freewheel gear (9) integral with the wheel (8). The part of the chain (14) not subjected to the effort rolls on the wheel (16) to follow a direction parallel to the base of the scooter. The end of the chain (14) is connected to the bungee tensioner (18) whose anchor point (24) is located below and at the front of the board (7).
La partie de la chaîne (14) soumise à l'effort par son bras de levier positif crée un couple par rapport à l'axe (22) qui permet de maintenir la roue (8) plaquée au sol pour assurer l'adhérence nécessaire à la traction de la trottinette. The part of the chain (14) subjected to effort by its positive lever arm creates a torque with respect to the axis (22) which keeps the wheel (8) pressed to the ground to ensure the necessary adhesion to the pull of the scooter.
