Definitions
- the present invention is in the field of urban mobility, and relates to an individual means of transport allowing walking at a higher speed than that of normal walking, without any skating movement, without running backswing, and without modifying the rhythm, amplitude or longitudinal stability of natural walking.
- This means of motorized transport constitutes a new solution for individual mobility, in a rather urban environment, which achieves an advantageous combination of walking and the moving sidewalk, and which could be defined as a kind of "on-board and progressive treadmill". which takes place under the walker's shoes.
- the invention thus combines more advantages than all currently existing means of individual urban transport, including in particular speed, safety, comfort of use, very small personal size and immediate control without learning.
- each shoe houses a relatively rigid plate connected to caterpillars in the toe and heel parts, respectively, which are connected by a relatively flexible part. The whole is designed to neutralize forces disrupting its functioning while walking while the soft part helps the shoe bend naturally to maintain natural balance and walking motion. Also, the soft part can be fitted with ribs or hinges for easier bending than twisting.
- the relatively stiff front and back plates can be made of materials that can be twisted and bent, but to a lesser extent than the soft part.
- the patent application WO1995035136A1 relates not to motorized equipment, but to a track roller skate unique “roller” type.
- the problem is not the same as that of a motorized skate.
- the purpose of this non-motorized single-track skate is to improve the power transmitted by the supporting foot during a “skate” movement.
- FIG. 1 represents a very schematic view of the mobility equipment formed by a pair of motorized skates (1, 2) seen from below, the soles of the feet being represented to facilitate understanding of the operation and not forming part of the invention.
- Each shoe is formed by a rigid plate (30) having the general shape of a sole supporting a front mobile train (10) and a rear mobile train (20).
- 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 external rotor, driving the tracks.
- This motor can be equipped with a reduction gear, for example in the form of an epicyclic gear train, and with a step-by-step actuator controlled according to commands transmitted by the user.
- the rear axle (20) also has a housing for receiving electric batteries (51 to 54).
- the longitudinal axis (16) of the nose gear (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).
- angles can be adjustable to adapt to the valgus of the user, for example between 10 and 20°.
- the locomotion equipment consists of a pair of skates comprising rolling or sliding trains (10, 20) connected to a sole (30) which is fixed to the feet either in the form of special shoes, or as additional skates attached under the shoes .
- Each pad (1, 2) is made up of a frame (22) equipped with moving 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 rolling or sliding, and 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.
- the plate (30) is mounted with an orientation, in its own plane, obliquely relative to the direction of movement of the mobile trains (10, 20).
- the plate (30) can be mounted at a point of the frame on a means of rotation (40), pivot or ball-and-socket system, making it possible to preset this orientation.
- the oblique orientation of the frame can create overhangs of the foot in relation to the support points of the rolling or sliding gears, which can induce lateral instability of the pads if the width of the support polygon defined by the position rolling or sliding trains is insufficient.
- the present invention is based on the lateral offset relative to each other of the rolling or sliding gears. This shift makes it possible to position said rolling or sliding trains 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 that is to say obliquely relative to said longitudinal axis. Consequently, the width of the plate can be reduced to that of said support polygon.
- the pivot can advantageously be made of elastic material of suitable stiffness, allowing the plate which tilts with the foot along its roll axis to deform the pivot such that the chassis and its mobile trains remain flat parallel to the ground.
- This configurable orientation of the plate relative to the direction of movement of the moving gears can be obtained by means of rotation (40) or swiveling, making it possible to preset the orientation of the plate relative to the chassis, and which can be coupled to a locking device (7) making it possible to obtain the blocking of the rolling direction during use of the skates.
- an articulated mechanism can advantageously be produced which provides a coupling between a point of the plate (30) and each lateral positioning mechanism.
- This mechanism can be an articulated parallelogram, maintaining the parallelism of the rolling or sliding gears, and coupled by a pivot at a point of the plate.
- spacer-tightening cams actuated by the rotation of the plate on its pivot, with, if necessary, transmission rods to the rolling or sliding gears to be shifted.
- slides can advantageously be used, which hold the moving gears on the chassis while allowing them to slide laterally, each being coupled to an articulated attachment point (5) of the plate.
- each shiftable mobile train can then be obtained thanks to this coupling if the orientation of the plate is itself locked.
- the common roller can advantageously be composed of an inner support cylinder, around which are mounted the outer cylinders acting as pulleys, at least one of them being free to slide laterally along the inner cylinder during adjustment.
- a first particular embodiment of the invention is an in-line roller skate consisting of a sole (30) equipped with two mobile running gears (10, 20), each comprising two in-line wheels (12, 13; 22, 23) , and a plate mounted on the chassis by a pivot (40) making it possible to preset its orientation obliquely with respect to the direction of travel of the running gear ( FIG. 2 ).
- the pivot (40) is made of elastic material of the polymer type, its stiffness sufficient to keep the plate stable in the normal position (excluding pushing force), but letting it tilt in roll with the foot when pushing on the skate, so that the four wheels remain flat on the ground when pushing the foot if the two running gears are offset.
- the shift mechanism is a slide rail (6), integral with the front running gear, and sliding laterally along a rail fixed to the chassis.
- the coupling of the plate to the lateral offset mechanism (6) of the front running gear is obtained by a fork (5) secured to the front of the plate, and acting laterally on the offset slider (6).
- the rail secured to 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 skate or shod).
- 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. Locking occurs as soon as the spreading force is released, and is reinforced by the weight of the skater when he places his foot on the ground.
- a second particular embodiment of the invention is a skate with two tracks ( FIG. 1 ), consisting of a frame equipped with two moving trains (10, 20), each consisting of a caterpillar with two rollers at the ends, said caterpillars rolling in the same direction.
- the plate (30) supporting the shoe is mounted on a pivot making it possible to preset its orientation, in its own plane, obliquely with respect to the direction of travel of the running gear (16, 26).
- the mechanism for shifting and locking the front running gear, as well as its coupling means to the plate, are identical to those of the roller constituting the first particular embodiment.
- a variant of this second particular embodiment consists in pooling the rear roller of the front track and the front roller of the rear track (39) .
- the pair of rolling or sliding skates attached to the feet can be made in the form of special shoes, or as additional skates attached under the shoes, each skate being composed of a frame equipped with several mobile trains, all rolling or sliding according to the same direction, and a plate, specific in the case of an additional skate, or constituted by the sole in the case of a special shoe, characterized in that the said plate is mounted obliquely with respect to the direction of movement of the mobile trains, and that at least one of the mobile trains is offset laterally with respect to the others so that all the mobile trains support the support points of the foot while making it possible to maintain the width of the pad close to that of the foot.
- At least one wheeled train At least one wheeled train
- the pair of runners comprises, for at least one of its mobile trains (10, 20), a fixed assembly of wheels rolling in the same direction, at least one of which, for each train, is driven by the engine (50).
- each train (10, 20) includes a motor wheel.
- At least one crawler train At least one crawler train
- the pair of pads comprises, for at least one of the moving gears (10, 20), a caterpillar.
- At least one of the mobile trains (10, 20) is composed of segments which can slide on the ground.
- the means for connecting the plate (30) with the moving gears (10, 20) are made of elastic material allowing the plate (30) to be tilted in roll without taking off all or part of the moving gears from the ground.
- the plate (30) is mounted on the chassis by means of rotation making it possible to preset the orientation of the plate with respect to the direction of movement of the moving gears (10, 20), said rotation means being coupled to a locking device making it possible to obtain the blocking of the rolling direction during use of the skates.
- a device for locking the orientation of the plate is obtained by notching the faces of the elements facing each other, held by an elastic system when the pad is not on the ground, said elastic system allowing the preset to be modified by hand, and being arranged in such a way that the weight of the user on the skate reinforces the effect.
- each mobile train (10, 20) is shiftable and comprises a means of coupling with the orientation of the plate (30) so that the shift mobile trains optimizes the support polygon in relation to the support points of the foot on the plate.
- the means for coupling the plate (30) to the lateral shift mechanism of a moving train (10, 20) is an articulated mechanical connection between the plate and the shift mechanism.
- the lateral shift mechanism of an undercarriage (10, 20) is a slide (6), which holds the undercarriage on the frame while allowing it to slide laterally under the action of the articulated link.
- each of the skates is completely integrated into a shoe.

La
Chaque patin est formé par une platine rigide (30) présentant la forme générale d'une semelle supportant un train mobile avant (10) et un train mobile arrière (20) . Cette platine est formée de deux parties articulées selon un axe transversal (39), la partie avant (37) correspondant sensiblement aux orteils, et la partie arrière (38) correspondant à la plante et au talon. Les trains avant (10) et arrière (20) sont motorisés par un moteur commun (50) intérieur au rouleau commun aux trains avant et arrière, par exemple un moteur électrique à rotor extérieur, entraînant des chenilles. Ce moteur peut être équipé d'un réducteur, par exemple sous forme de train épicycloïdal, et d'un actionneur pas-à-pas piloté en fonction de commandes transmises par l'utilisateur.Each shoe is formed by a rigid plate (30) having the general shape of a sole supporting a front mobile train (10) and a rear mobile train (20). 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 external rotor, driving the tracks. This motor can be equipped with a reduction gear, for example in the form of an epicyclic gear train, and with a step-by-step actuator controlled according to 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).

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 offset laterally relative 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 adapt to the valgus of the user, for example between 10 and 20°.
La
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.Each pad (1, 2) is made up of a frame (22) equipped with moving 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 rolling or sliding, and 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 shoe, the plate (30) is mounted with an orientation, in its own plane, obliquely relative to the direction of movement of the mobile trains (10, 20). Advantageously, the plate (30) can be mounted at a point of the frame on a means of rotation (40), pivot or ball-and-socket system, making it possible to preset this orientation.
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 frame can create overhangs of the foot in relation to the support points of the rolling or sliding gears, which can induce lateral instability of the pads if the width of the support polygon defined by the position rolling or sliding trains 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.In order to reduce the width of said support polygon while compensating for said cantilever of the support points of the feet, the present invention is based on the lateral offset relative to each other of the rolling or sliding gears. This shift makes it possible to position said rolling or sliding trains 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 that is to say obliquely relative to said longitudinal axis. Consequently, the width of the plate can be reduced to that of said support polygon.
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.However, when the plate of the skate that is the subject of this invention is oriented obliquely, a diagonal inclination of the supporting leg, for example during the skating push, risks taking off from the ground, at least partially, the rolling or sliding gears more on the outside of the feet. To counter this effect and keep all 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 along its roll axis to deform the pivot such that the chassis and its mobile trains 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 with respect to the direction of rolling or sliding of the running gear, it may be advantageous to make this orientation configurable as well as the offset between them of the running or sliding gear .
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 gears can be obtained by means of rotation (40) or swiveling, making it possible to preset the orientation of the plate relative to the chassis, and which can be coupled to a locking device (7) making it possible to obtain the blocking of the rolling direction during use of the skates.
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.In order to avoid overhangs of the foot in relation to the support polygon of the moving trains, it may be necessary to add a mechanism for pre-adjusting the lateral positioning of certain moving trains, so that the offset of the moving gear optimizes the support polygon in relation to the support points of the foot on the plate.
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 this case, an articulated mechanism can advantageously be produced which provides 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, maintaining the parallelism of the rolling or sliding gears, and coupled by a pivot at a point of 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 spacer-tightening cams actuated by the rotation of the plate on its pivot, with, if necessary, transmission rods to the rolling 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 chassis 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 mobile train can then be obtained thanks to 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.When certain undercarriages 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 are mounted the outer cylinders acting as pulleys, at least one of them being free to slide laterally along the inner cylinder during adjustment.
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 (
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 elastic material of the polymer type, its stiffness sufficient to keep the plate stable in the normal position (excluding pushing force), but letting it tilt in roll with the foot when pushing on the skate, so that the four wheels remain flat on the ground when pushing the foot 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 slide rail (6), integral with the front running gear, and sliding laterally along a rail fixed to the chassis.
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 offset mechanism (6) of the front running gear is obtained by a fork (5) secured to the front of the plate, and acting laterally on the offset slider (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 secured to 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 skate or shod). 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. Locking occurs as soon as the spreading force is released, and is reinforced by the weight of the skater when he places his foot on the ground.
Un second mode particulier de réalisation de l'invention est un patin à deux chenilles (
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 attached to 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 mechanism for shifting and locking the front running gear, as well as its coupling means to the plate, are identical to those of the roller 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 pooling 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 articulation of the metatarsals, that is to say at the widest point of the foot.
Différentes variantes de réalisation sont possibles.Different embodiments are possible.
La paire de patins roulants ou glissants se fixant aux pieds peut être réalisée sous forme de chaussures spéciales, ou comme patins additionnels attachés sous les chaussures, chaque patin étant composé d'un châssis équipé de plusieurs trains mobiles, roulant ou glissant tous selon la même direction, et d'une platine, spécifique dans le cas d'un patin additionnel, ou constituée par la semelle dans le cas d'une chaussure spéciale, caractérisée en ce que ladite platine est montée en oblique par rapport à la direction de déplacement des trains mobiles, et qu'au moins un des trains mobiles est décalé latéralement par rapport aux autres de façon à ce que l'ensemble des trains mobiles supporte les points d'appui du pied tout en permettant de maintenir la largeur du patin proche de celle du pied.The pair of rolling or sliding skates attached to the feet can be made in the form of special shoes, or as additional skates attached under the shoes, each skate being composed of a frame equipped with several mobile trains, all rolling or sliding according to the same direction, and a plate, specific in the case of an additional skate, or constituted by the sole in the case of a special shoe, characterized in that the said plate is mounted obliquely with respect to the direction of movement of the mobile trains, and that at least one of the mobile trains is offset laterally with respect to the others so that all the mobile trains support the support points of the foot while making it possible to maintain the width of the pad close to that of the foot.
Selon une première variante, la paire de patins comporte, pour au moins un de ses trains mobiles (10, 20), un assemblage fixe de roues roulant dans la même direction dont l'une au moins, pour chaque train, est entraînée par le moteur (50). Alternativement, chaque train (10, 20) comporte une rouemoteur.According to a first variant, the pair of runners comprises, for at least one of its mobile trains (10, 20), a fixed assembly of wheels rolling in the same direction, at least one of which, for each train, is driven by the engine (50). Alternatively, each train (10, 20) includes a motor wheel.
Selon une deuxième variante, la paire de patins comporte, pour un des trains mobiles (10, 20) au moins, une chenille.According to a second variant, the pair of pads comprises, for at least one of the moving gears (10, 20), a caterpillar.
Selon une troisième variante, au moins un des trains mobiles (10, 20) est composé de segments pouvant glisser sur le sol.According to a third variant, at least one of the mobile trains (10, 20) is composed of segments which can slide on the ground.
Selon une autre variante, les moyens de liaison de la platine (30) avec les trains mobiles (10, 20) sont en matière élastique permettant que la platine (30) soit inclinée en roulis sans décoller du sol tout ou partie des trains mobiles.According to another variant, the means for connecting the plate (30) with the moving gears (10, 20) are made of elastic material allowing the plate (30) to be tilted in roll without taking off all or part of the moving gears from the ground.
Selon une autre variante, la platine (30) est montée sur le châssis par un moyen de rotation permettant de prérégler l'orientation de la platine par rapport à la direction de déplacement des trains mobiles (10, 20), ledit moyen de rotation étant couplé à un dispositif de verrouillage permettant d'obtenir le blocage de la direction de roulage pendant l'utilisation des patins.According to another variant, the plate (30) is mounted on the chassis by means of rotation making it possible to preset the orientation of the plate with respect to the direction of movement of the moving gears (10, 20), said rotation means being coupled to a locking device making it possible to obtain the blocking of the rolling direction during use of the skates.
Selon une autre variante, un dispositif de verrouillage de l'orientation de la platine est obtenu par un crantage des faces des éléments en vis-à-vis, maintenu par un système élastique lorsque le patin n'est pas au sol, ledit système élastique permettant de modifier à la main le préréglage, et étant disposé de telle sorte que le poids de l'utilisateur sur le patin en renforce l'effet.According to another variant, a device for locking the orientation of the plate is obtained by notching the faces of the elements facing each other, held by an elastic system when the pad is not on the ground, said elastic system allowing the preset to be modified by hand, and being arranged in such a way that the weight of the user on the skate reinforces the effect.
Selon une autre variante, chaque train mobile (10, 20) est décalable et comporte un moyen de couplage avec l'orientation de la platine (30) 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.According to another variant, each mobile train (10, 20) is shiftable and comprises a means of coupling with the orientation of the plate (30) so that the shift mobile trains optimizes the support polygon in relation to the support points of the foot on the plate.
Selon une autre variante encore, pour chaque patin, le moyen de couplage de la platine (30) au mécanisme de décalage latéral d'un train mobile (10, 20) est une liaison mécanique articulée entre la platine et le mécanisme de décalage.According to yet another variant, for each pad, the means for coupling the plate (30) to the lateral shift mechanism of a moving train (10, 20) is an articulated mechanical connection between the plate and the shift mechanism.
Selon une autre variante, pour chaque patin, le mécanisme de décalage latéral d'un train roulant (10, 20) est une glissière (6), qui maintient le train roulant sur le châssis tout en le laissant coulisser latéralement sous l'action de la liaison articulée.According to another variant, for each pad, the lateral shift mechanism of an undercarriage (10, 20) is a slide (6), which holds the undercarriage on the frame while allowing it to slide laterally under the action of the articulated link.
Selon un mode de réalisation particulier, chacun des patins est complètement intégré à une chaussure.According to a particular embodiment, each of the skates is completely integrated into a shoe.
