ÉQUIPEMENT DE DÉPLACEMENT INDIVIDUEL CONSTITUÉ PAR UNE PAIREINDIVIDUAL TRAVEL EQUIPMENT CONSTITUTED BY A PAIR
DE PATINS MOTORISÉS MOTORIZED SKATES
Domaine de l'invention Field of the invention
La présente invention se situe dans le domaine de la mobilité urbaine, et concerne un moyen de déplacement individuel permettant de marcher à une vitesse plus élevée que celle de la marche normale, sans aucun mouvement de patinage, sans course de prise d'élan, et sans modifier le rythme, l'amplitude, ni la stabilité longitudinale de la marche naturelle . The present invention is in the field of urban mobility, and relates to an individual means of movement making it possible to walk at a higher speed than that of normal walking, without any skating movement, without backswing stroke, and without modifying the rhythm, amplitude or longitudinal stability of natural walking.
Ce moyen de déplacement motorisé constitue une nouvelle solution de mobilité individuelle, en milieu plutôt urbain, qui réalise une combinaison avantageuse de la marche à pied et du trottoir roulant, et qu'on pourrait définir comme une sorte de « tapis roulant embarqué et progressif » qui se déroule sous les chaussures du marcheur. L'invention cumule ainsi plus d'avantages que tous les moyens de déplacement individuel urbain existant actuellement, dont en particulier la rapidité, la sécurité, le confort d'utilisation, le très faible encombrement personnel et la maîtrise immédiate sans apprentissage . This motorized means of transport constitutes a new solution for individual mobility, in a rather urban environment, which achieves an advantageous combination of walking and moving sidewalks, and which could be defined as a kind of "onboard and progressive treadmill" which takes place under the shoes of the walker. The invention thus has more advantages than all the means of individual urban movement currently existing, including in particular speed, safety, comfort of use, very small personal space and immediate control without learning.
État de l ' art State of the art
On connaît dans l'état de la technique la demande de brevet W02018090135 décrivant article de transport personnel motorisé destiné à transporter une personne au moyen du port d'une paire de chaussures motorisées à assistance électrique, utilisée dans une action de marche avant normale qui fournit une vitesse de marche supplémentaire réglée sur la base d'une vitesse de marche prévue par l'utilisateur ; même la vitesse prévue change pendant une étape intermédiaire. La semelle de chacune des chaussures loge une plaque relativement rigide raccordée à des chenilles dans les parties d'orteil et de talon, respectivement, qui sont reliées par une partie relativement souple. L'ensemble est conçu pour neutraliser les forces perturbant son fonctionnement pendant la marche tandis que la partie souple aide à plier la chaussure naturellement pour maintenir l'équilibre et le mouvement de marche naturels. En outre, la partie souple peut être équipée de nervures ou de charnières pour une flexion plus facile que la torsion. Les plaques relativement rigides avant et arrière peuvent être composées de matériaux pouvant être tordus et pliés, mais dans une moindre mesure que la partie souple. Patent application WO2018090135 is known in the state of the art describing an article of motorized personal transport intended to transport a person by means of the wearing of a pair of electrically assisted motorized shoes, used in a normal forward action which provides an additional walking speed set on the basis of a walking speed predicted by the user; even the predicted speed changes during an intermediate stage. The sole of each of the shoes houses a relatively rigid plate connected to tracks in the toe and heel portions, respectively, which are connected by a relatively flexible portion. The set is designed to neutralize forces interfering with its functioning while walking while the flexible part helps to bend the shoe naturally to maintain natural balance and walking movement. In addition, the soft part can be fitted with ribs or hinges for easier bending than twisting. The relatively stiff front and rear plates can be made of materials that can be twisted and bent, but to a lesser extent than the soft part.
On connaît aussi le brevet international WO1995035136 décrivant un autre exemple de patin à une seule rangée de roulettes à porter sur une chaussure de sport ou tous terrains comprend au moins deux roulettes montées dans un cadre. La chaussure du patineur peut être fixée sur une plaque de support de la semelle assujettie au cadre. Afin d'aligner les roulettes, le cadre peut pivoter autour d'un axe (A) sensiblement perpendiculaire à la plaque de support de la semelle et être fixé en position avec la plaque de support de la semelle. International patent WO1995035136 is also known, describing another example of a skate with a single row of rollers to be worn on a sports or all-terrain shoe comprising at least two rollers mounted in a frame. The skater's shoe may be attached to a sole support plate secured to the frame. In order to align the casters, the frame can pivot about an axis (A) substantially perpendicular to the sole support plate and be secured in position with the sole support plate.
Inconvénients de l'art antérieur Disadvantages of the prior art
La solution proposée par la demande de brevet W02018090135 est basée sur l'utilisation d'une paire de chenilles avant et d'une paire de chenilles arrière, toutes les chenilles étant parallèles entre elles, et alignées deux à deux. Il en résulte un comportement hyperstatique qui n'est pas naturel pour un mouvement de marche où le pied n'est pas orienté strictement selon l'axe perpendiculaire au plan médian. Il en résulte une composante des forces transversales se traduisant par une perte d'énergie. La demande de brevet WO1995035136A1 concerne non pas un équipement motorisé, mais un patin à roulettes à piste unique de type « roller ». Le problème n'est pas le même que celui d'un patin motorisé. Le but de ce patin non motorisé à piste unique est d'améliorer la puissance transmise par le pied d'appui lors d'un mouvement de « patinette ». The solution proposed by patent application WO2018090135 is based on the use of a pair of front tracks and a pair of rear tracks, all the tracks being parallel to each other, and aligned two by two. This results in hyperstatic behavior which is not natural for a walking movement where the foot is not oriented strictly along the axis perpendicular to the median plane. This results in a component of transverse forces resulting in a loss of energy. The patent application WO1995035136A1 relates not to motorized equipment, but to a single-track roller skate of the “roller” type. The problem is not the same as that of a motorized skate. The goal of this non-motorized single track skate is to improve the power transmitted by the supporting foot during a “skate” movement.

This plate is formed of two parts articulated along a transverse axis (39), the front part (37) corresponding substantially to the toes, and the rear part (38) corresponding to the sole and the heel. The front (10) and rear (20) axles are motorized by a common motor (50) inside the roller common to the front and rear axles, for example an electric motor with an outer rotor, driving caterpillars. This motor can be equipped with a reduction gear, for example in the form of an epicyclic gear, and a stepping actuator controlled as a function of commands transmitted by the user.
Le train arrière (20) présente également un logement pour recevoir des batteries électriques (51 à 54) . The rear axle (20) also has a housing for receiving electric batteries (51 to 54).
L'axe longitudinal (16) du train avant (10) forme un angle d'environ 15° avec l'axe longitudinal (35) de la platine (30) . L'axe longitudinal (26) du train arrière (20) forme un angle d'environ 15° avec l'axe longitudinal (35) de la platine (30) . Ces deux axes longitudinaux (16, 35) sont décalés latéralement l'un par rapport à l'autre. The longitudinal axis (16) of the front axle (10) forms an angle of approximately 15 ° with the longitudinal axis (35) of the plate (30). The longitudinal axis (26) of the rear axle (20) forms an angle of approximately 15 ° with the longitudinal axis (35) of the plate (30). These two longitudinal axes (16, 35) are laterally offset with respect to each other.
Ces angles peuvent être ajustables pour s'adapter au valgus de l'utilisateur, par exemple entre 10 et 20°. These angles can be adjustable to suit the user's valgus, for example between 10 and 20 °.
Exemple de réalisation Example of realization
La figure 2 correspond à un premier mode de réalisation d'un patin. L'équipement de locomotion est constitué d'une paire de patins comportant des trains roulants ou glissants (10, 20) reliés à une semelle (30) se fixant aux pieds soit sous forme de chaussures spéciales, soit comme patins additionnels attachés sous les chaussures. Chaque patin (1, 2) est composé d'un châssis (22) équipé de trains mobiles (10,11 ; 20,21), c'est-à-dire roulant (12, 13, 22, 23) ou glissant sur le sol, chaque train mobile étant un assemblage solidaire de roues, de chenilles, ou de segments glissants, tous ces trains mobiles ayant la même direction de déplacement, c'est-à-dire de roulage ou de glisse, et d'une platine, spécifique dans le cas d'une semelle (30) fixée sous les chaussures, ou constituée par la semelle (30) dans le cas d'une chaussure spéciale. FIG. 2 corresponds to a first embodiment of a pad. The locomotive equipment consists of a pair of skates comprising running or sliding gears (10, 20) connected to a sole (30) which attaches to the feet either in the form of special shoes or as additional skates attached under the shoes . Each shoe (1, 2) is composed of a frame (22) equipped with mobile trains (10,11; 20,21), that is to say rolling (12, 13, 22, 23) or sliding on the ground, each moving train being an integral assembly of wheels, tracks, or sliding segments, all these moving trains having the same direction of movement, that is to say of running or sliding, and of a plate , specific in the case of a sole (30) fixed under the shoes, or constituted by the sole (30) in the case of a special shoe.
Pour chaque patin, la platine (30) est montée avec une orientation, dans son propre plan, en oblique par rapport à la direction de déplacement des trains mobiles (10, 20) . Avantageusement, la platine (30) peut être montée en un point du châssis sur un moyen de rotation (40), pivot ou système de rotulage, permettant de prérégler cette orientation. For each pad, the plate (30) is mounted with an orientation, in its own plane, obliquely with respect to the direction of movement of the moving trains (10, 20). Advantageously, the plate (30) can be mounted at a point of the frame on a means of rotation (40), pivot or swivel system, allowing this orientation to be preset.
L'orientation en oblique de la platine peut créer des porte-à-faux du pied par rapport aux points de support des trains roulants ou glissants, ce qui peut induire une instabilité latérale des patins si la largeur du polygone de sustentation défini par la position des trains roulants ou glissants est insuffisante. The oblique orientation of the plate can create overhangs of the foot in relation to the support points of the running or sliding gears, which can induce lateral instability of the shoes if the width of the support polygon defined by the position running or sliding gear is insufficient.
Afin de réduire la largeur dudit polygone de sustentation tout en compensant ledit porte-à-faux des points d'appui des pieds, la présente invention est basée sur le décalage latéral l'un par rapport à l'autre des trains roulants ou glissants. Ce décalage permet de positionner lesdits trains roulants ou glissants le long de l'axe longitudinal de la platine (30) pour supporter les points d'appui du pied, tout en les laissant rouler ou glisser dans la direction de déplacement, c'est-à-dire en oblique par rapport audit axe longitudinal. En conséquence, la largeur de la platine peut être réduite à celle dudit polygone de sustentation. Cependant, lorsque la platine du patin objet de cette invention est orientée en oblique, une inclinaison en diagonale de la jambe porteuse, par exemple lors de la poussée de patinage, risque de décoller du sol, au moins partiellement, les trains roulants ou glissants les plus à l'extérieur des pieds. Pour contrer cet effet et maintenir au sol la totalité des trains mobiles, le pivot peut avantageusement être réalisé en matière élastique d'une raideur adaptée, permettant à la platine qui s'incline avec le pied selon son axe de roulis de déformer le pivot de telle sorte que le châssis et ses trains mobiles restent à plat parallèlement au sol. In order to reduce the width of said support polygon while compensating for said overhang of the support points of the feet, the present invention is based on the lateral offset with respect to one another of the running or sliding gears. This offset makes it possible to position said running or sliding gears along the longitudinal axis of the plate (30) to support the support points of the foot, while letting them roll or slide in the direction of movement, that is to say that is to say obliquely with respect to said longitudinal axis. Consequently, the width of the plate can be reduced to that of said support polygon. However, when the plate of the skate object of this invention is oriented obliquely, a diagonal inclination of the load-bearing leg, for example during the skating thrust, risks taking off from the ground, at least partially, the running or sliding gears. more on the outside of the feet. To counter this effect and keep all of the moving gears on the ground, the pivot can advantageously be made of elastic material of suitable stiffness, allowing the plate which tilts with the foot according to its roll axis to deform the pivot of such that the chassis and its moving gears remain flat parallel to the ground.
Dans le cas où il est nécessaire d'obtenir une orientation importante de la platine par rapport à la direction de roulage ou de glisse des trains roulants, il peut être avantageux de rendre paramétrable cette orientation ainsi que le décalage entre eux des trains roulants ou glissants. In the case where it is necessary to obtain a significant orientation of the plate relative to the running or sliding direction of the running gear, it may be advantageous to make this orientation as well as the offset between them of the running or sliding gear trains configurable. .
Cette orientation paramétrable de la platine par rapport à la direction de déplacement des trains mobiles peut être obtenue par un moyen de rotation (40) ou de rotulage, permettant de prérégler l'orientation de la platine par rapport au châssis, et pouvant être couplé à un dispositif de verrouillage (7) permettant d'obtenir le blocage de la direction de roulage pendant l'utilisation des patins. This configurable orientation of the plate relative to the direction of movement of the moving trains can be obtained by means of rotation (40) or swivel, making it possible to pre-adjust the orientation of the plate relative to the frame, and being able to be coupled to a locking device (7) making it possible to obtain the locking of the rolling direction during the use of the pads.
Afin d'éviter les porte-à-faux du pied par rapport au polygone de sustentation des trains mobiles, il peut être nécessaire d'y ajouter un mécanisme de préréglage du positionnement latéral de certains trains mobiles, de façon à ce que le décalage des trains mobiles optimise le polygone de sustentation par rapport aux points d'appui du pied sur la platine . Dans ce cas, on peut avantageusement réaliser un mécanisme articulé réalisant un couplage entre un point de la platine (30) et chaque mécanisme de positionnement latéral. In order to avoid overhangs of the foot with respect to the support polygon of the mobile trains, it may be necessary to add a pre-adjustment mechanism for the lateral positioning of certain mobile trains, so that the offset of the mobile trains optimize the support polygon in relation to the support points of the foot on the plate. In this case, it is advantageously possible to produce an articulated mechanism providing a coupling between a point of the plate (30) and each lateral positioning mechanism.
Ce mécanisme peut être un parallélogramme articulé, conservant le parallélisme des trains roulants ou glissants, et couplé par un pivot en un point de la platine. This mechanism can be an articulated parallelogram, preserving the parallelism of the rolling or sliding gears, and coupled by a pivot at a point on the plate.
On peut également utiliser des cames d'espacement- resserrement actionnées par la rotation de la platine sur son pivot, avec, si nécessaire, des biellettes de transmission vers les trains roulants ou glissants à décaler. It is also possible to use spacing-tightening cams actuated by the rotation of the plate on its pivot, with, if necessary, transmission rods towards the running or sliding gears to be shifted.
Enfin on peut avantageusement utiliser des glissières, qui maintiennent les trains mobiles sur le châssis tout en les laissant coulisser latéralement, chacun étant couplé à point d'attache articulé (5) de la platine. Finally, slides can advantageously be used, which hold the moving gears on the frame while allowing them to slide laterally, each being coupled to an articulated attachment point (5) of the plate.
Le verrouillage de chaque train mobile décalable peut alors être obtenu grâce à ce couplage si l'orientation de la platine est elle-même verrouillée. The locking of each shiftable moving gear can then be obtained by virtue of this coupling if the orientation of the plate is itself locked.
Lorsque certains trains roulants sont des chenilles ayant un rouleau commun, leur décalage latéral est nécessairement supérieur à la largeur de chenille, puisque les chenilles ne peuvent pas se recouvrir. Dans le cas où ledit décalage latéral est rendu paramétrable, le rouleau commun peut avantageusement être composé d'un cylindre intérieur de support, autour duquel sont montés les cylindres extérieurs jouant le rôle de poulies, l'un d'entre eux au moins étant libre de glisser latéralement le long du cylindre intérieur lors du réglage . Un premier mode particulier de réalisation de l'invention est un roller en ligne composé d'une semelle (30) équipée de deux trains mobiles (10, 20) roulants, chacun comportant deux roues en ligne (12, 13 ; 22, 23), et d'une platine montée sur le châssis par un pivot (40) permettant de prérégler son orientation en oblique par rapport à la direction de roulage des trains roulants (FIG. 2) . When certain running gears are tracks having a common roller, their lateral offset is necessarily greater than the track width, since the tracks cannot overlap. In the case where said lateral offset is made configurable, the common roller can advantageously be composed of an inner support cylinder, around which the outer cylinders are mounted playing the role of pulleys, at least one of them being free. slide sideways along the inner cylinder when adjusting. A first particular embodiment of the invention is an in-line roller skate composed of a sole (30) equipped with two rolling mobile trains (10, 20), each comprising two in-line wheels (12, 13; 22, 23) , and a plate mounted on the frame by a pivot (40) allowing its orientation to be preset obliquely with respect to the running direction of the running gear (FIG. 2).
Le pivot (40) est en matière élastique de type polymère, sa raideur suffisant à maintenir stable la platine en position normale (hors effort de poussée) , mais le laissant s'incliner en roulis avec le pied lors de la poussée sur le patin, afin que les quatre roues restent plaquées au sol lors de la poussée du pied si les deux trains roulants sont décalés. The pivot (40) is made of an elastic material of the polymer type, its stiffness sufficient to keep the plate stable in the normal position (excluding pushing force), but allowing it to tilt in roll with the foot when pushing on the skate, so that the four wheels remain flat on the ground when the foot is pushed if the two running gears are offset.
Dans ce mode de réalisation, seul le train roulant avant est décalable par rapport au train roulant arrière, lequel reste solidaire du châssis. In this embodiment, only the front running gear is shiftable relative to the rear running gear, which remains integral with the chassis.
Le mécanisme de décalage est une glissière à rails (6), solidaire du train roulant avant, et coulissant latéralement le long d'un rail fixé au châssis. The shift mechanism is a rail slide (6), integral with the front running gear, and sliding laterally along a rail fixed to the frame.
Le couplage de la platine au mécanisme de décalage latéral ( 6) du train roulant avant est obtenu par une fourchette (5) solidaire de l'avant de la platine, et agissant latéralement sur la glissière de décalage (6) . The coupling of the plate to the lateral shift mechanism (6) of the front running gear is obtained by a fork (5) integral with the front of the plate, and acting laterally on the shift slide (6).
Le rail solidaire du châssis intègre un ressort le plaquant contre la glissière (6), les deux surfaces en vis-à- vis étant crantées (7) de façon à obtenir le verrouillage dans toutes les conditions (patin libre ou chaussé) . Le préréglage du décalage s'effectue manuellement, par écartement temporaire du train roulant avant par rapport de la platine, qui neutralise l'effort de compression du ressort, et en ajustant le décalage latéral. Le verrouillage se produit dès le relâchement de l'effort d'écartement, et se trouve renforcé par le poids du patineur lorsqu'il pose son pied au sol. The rail integral with the frame incorporates a spring pressing it against the slide (6), the two facing surfaces being notched (7) so as to obtain locking in all conditions (free or shod shoe). The offset is preset manually, by temporarily moving the front running gear away from the plate, which neutralizes the compression force of the spring, and adjusting the lateral offset. The locking occurs as soon as the spreading force is released, and is reinforced by the weight of the skater when he puts his foot on the ground.
Alternative à chenillette Alternative to caterpillar
Un second mode particulier de réalisation de l'invention est un patin à deux chenilles (FIG. 1), composé d'un châssis équipé de deux trains mobiles roulants (10, 20), chacun étant constitué d'une chenille à deux rouleaux en extrémités, lesdites chenilles roulant selon la même direction. La platine (30) supportant la chaussure est montée sur un pivot permettant de prérégler son orientation, dans son propre plan, en oblique par rapport à la direction de roulage des trains roulants (16, 26). A second particular embodiment of the invention is a shoe with two tracks (FIG. 1), composed of a frame equipped with two mobile running gears (10, 20), each consisting of a track with two rollers in ends, said tracks rolling in the same direction. The plate (30) supporting the boot is mounted on a pivot making it possible to preset its orientation, in its own plane, obliquely with respect to the running direction of the running gear (16, 26).
Seul le train roulant avant est décalable par rapport au train roulant arrière, lequel reste solidaire du châssis . Only the front running gear can be shifted relative to the rear running gear, which remains integral with the chassis.
Le mécanisme de décalage et de verrouillage du train roulant avant, ainsi que son moyen de couplage à la platine, sont identiques à ceux du roller constituant le premier mode particulier de réalisation. The shifting and locking mechanism of the front running gear, as well as its coupling means to the plate, are identical to those of the roller skate constituting the first particular embodiment.
Une variante de ce second mode particulier de réalisation, consiste à mettre en commun le rouleau arrière de la chenille avant et le rouleau avant de la chenille arrière (39) . A variant of this second particular embodiment consists in combining the rear roller of the front track and the front roller of the rear track (39).
Cette variante est particulièrement avantageuse puisque le rouleau commun, au moins deux fois plus long que les autres, est idéalement situé au niveau de l'articulation des métatarsiens, c'est-à-dire à l'endroit le plus large du pied. This variant is particularly advantageous since the common roller, at least twice as long as the others, is ideally located at the level of the metatarsal joint, that is to say at the widest point of the foot.
