La demande EP0561125 , par exemple, décrit un dispositif permettant d'assurer et de diriger un élève lors de la pratique du ski. Ce dispositif se compose principalement d'un harnais qui est porté par l'élève et d'une laisse sans fin reliée audit harnais.

Le système 1 comprend en outre un dispositif d'accouplement 2.System 1 further comprises a coupling device 2.

Le dispositif d'accouplement 2 comprend au moins deux modules de fixation 6, 6'. Chaque module de fixation 6, 6' est conçu pour être fixé à un patin 8, 8'. Les deux modules de fixation 6, 6' sont reliés entre eux par un corps 7. Le corps 7 est donc relié aux deux modules de fixation 6, 6'. Avantageusement, chaque extrémité du corps 7 est relié à un module de fixation. De plus, le corps 7 s'étend entre les deux modules de fixation 6, 6'.The coupling device 2 comprises at least two fixing modules 6, 6'. Each fixing module 6, 6' is designed to be fixed to a shoe 8, 8'. The two fixing modules 6, 6' are interconnected by a body 7. Body 7 is therefore connected to the two attachment modules 6, 6'. Advantageously, each end of the body 7 is connected to a fixing module. Moreover, the body 7 extends between the two attachment modules 6, 6'.

Un module de fixation 6 selon un mode de réalisation préférentiel de l'invention est illustré sur la figure 2. Le module de fixation 6 comprend au moins un élément de fixation 61 pour sa fixation au patin 8, 8' et au moins un moyen de liaison 62 pour sa liaison au corps 7 du dispositif d'accouplement 2.A fixing module 6 according to a preferred embodiment of the invention is illustrated in the figure 2 . The fixing module 6 comprises at least one fixing element 61 for its fixing to the shoe 8, 8' and at least one connecting means 62 for its connection to the body 7 of the coupling device 2.

L'élément de fixation 61 peut comprendre une mâchoire pour être fixé de manière réversible à un patin. Par exemple, l'élément de fixation 61 peut comprendre un système de ventouse et/ou de serrage. Dans un mode de réalisation illustré sur a figure 7, l'élément de fixation comprend une mâchoire.Attachment 61 may include a jaw for reversibly attaching to a skate. For example, the fixing element 61 can comprise a suction cup and/or tightening system. In one embodiment illustrated on a figure 7 , the fastening element comprises a jaw.

Le moyen de liaison 62 est destiné à coopérer avec un moyen de liaison du corps 7. Le moyen de liaison 62 est préférentiellement conçu pour former avec le corps 7, une liaison rotule. Le moyen de liaison 62 du module de fixation 6 illustré figure 2 comprend une liaison rotule femelle mais pourrait comprendre une liaison rotule mâle. Comme illustré sur la figure 8, le moyen de liaison permet de recevoir un moyen de liaison complémentaire d'un chariot 33.The connecting means 62 is intended to cooperate with a connecting means of the body 7. The connecting means 62 is preferably designed to form with the body 7, a ball joint. The connecting means 62 of the fixing module 6 illustrated picture 2 includes a female ball joint but could include a male ball joint. As illustrated on the figure 8 , the connecting means makes it possible to receive a connecting means complementary to a carriage 33.

Le module de fixation 6 comprend en outre un connecteur femelle 65 pour raccorder un brin de guidage 3.The fixing module 6 further comprises a female connector 65 for connecting a guide strand 3.

Le dispositif d'accouplement 2 peut comprendre en outre au moins un brin 64 dont une première extrémité est reliée au module de fixation 6 et dont la seconde extrémité est conçue pour être attachée à l'élève 5 afin de l'aider à maintenir une position vers l'avant. Ce brin 64 permet d'aider les élèves, en particuliers les enfants en bas âge, à maintenir leur bassin vers l'avant des patins. Le brin 64 permet de relier le module de fixation 6 au corps de l'élève 5.The coupling device 2 may further comprise at least one strand 64, a first end of which is connected to the fixing module 6 and the second end of which is designed to be attached to the pupil 5 in order to help him maintain a position. forward. This strand 64 helps the students, especially young children, to keep their pelvis forward of the skates. The strand 64 makes it possible to connect the fixing module 6 to the student's body 5.

Ledit brin 64 peut comprendre un enrouleur automatique 63 et/ou un moyen de réglage de la longueur du brin. L'enrouleur automatique 63 permet de garder le brin 64 sous tension. L'enrouleur automatique 63 permet également de bloquer le déroulage du brin 64 lorsque celui-ci atteint une longueur maximale prédéfinie. Dans un mode de réalisation, l'enrouleur automatique comprend un moyen pour régler ladite longueur prédéfinie, par exemple, un bouton poussoir (non-représenté). Le bouton poussoir permet par exemple de libérer l'enrouleur d'un ressort de rappel et de modifier alors la longueur prédéfinie du brin 64.Said strand 64 may comprise an automatic winder 63 and/or a means for adjusting the length of the strand. The automatic winder 63 keeps the strand 64 under tension. The automatic winder 63 also makes it possible to block the unwinding of the strand 64 when the latter reaches a predefined maximum length. In one embodiment, the automatic winder comprises a means for adjusting said predefined length, for example, a push button (not shown). The push button makes it possible, for example, to release the winder from a return spring and then modify the predefined length of the strand 64.

D'autre part, le au moins un brin 64 peut servir de guide visuel pour exercer les prises de carres en mettant en évidence les mouvements du bassin. La deuxième extrémité comprend préférentiellement des attaches réversibles de type VELCRO® ou un mousqueton pour sa fixation au corps de l'élève. Préférentiellement, le brin 64 est conçue pour être fixé aux vêtements de l'élève, par exemple au niveau de la ceinture de façon à l'empêcher de basculer son bassin en arrière. Ces attaches sont conçues pour se détacher en cas de forte tension sur le brin.On the other hand, the at least one strand 64 can serve as a visual guide for practicing edge grips by highlighting the movements of the pelvis. The second end preferably comprises reversible fasteners of the VELCRO ® type or a carabiner for its attachment to the student's body. Preferably, the strand 64 is designed to be attached to the student's clothing, for example at the level of the belt so as to prevent him from tilting his pelvis backwards. These fasteners are designed to come loose in the event of strong tension on the strand.

Dans un mode de réalisation, l'invention concerne un dispositif de maintien de position d'un élève comprenant un module de fixation 6 destiné à être fixé sur un patin, le dispositif comprenant au moins un brin 64 dont une première extrémité est reliée au module de fixation 6 et dont la seconde extrémité est conçue pour être attachée à l'élève 5, préférentiellement afin de l'aider à maintenir une position vers l'avant. Ledit brin 64 peut comprendre un enrouleur automatique 63 et/ou un moyen de réglage de la longueur du brin, préférentiellement fixé au module de fixation 6.In one embodiment, the invention relates to a device for maintaining a student's position comprising a fixing module 6 intended to be fixed to a skate, the device comprising at least one strand 64, a first end of which is connected to the module fixing 6 and whose second end is designed to be attached to the pupil 5, preferably in order to help him maintain a forward position.

Le module de fixation 6 peut alors être conçu pour s'adapter sur un ski ou une planche des neiges.The attachment module 6 can then be designed to fit on a ski or a snowboard.

Le dispositif d'accouplement 2 dans son ensemble est décrit ci-après en référence aux figures 3, 4, 5, 9 et 10.The coupling device 2 as a whole is described below with reference to the figures 3, 4, 5 , 9 and 10 .

Ledit dispositif d'accouplement 2 permet avantageusement, d'une part, de forcer l'élève 5 à garder ses deux patins 8 dans une plage de distance prédéterminée, et d'autre part, de limiter la divergence et la convergence des patins.Said coupling device 2 advantageously makes it possible, on the one hand, to force the student 5 to keep his two pads 8 within a range of predetermined distance, and on the other hand, to limit the divergence and convergence of the pads.

Le dispositif d'accouplement 2 est conçu pour autoriser au moins une translation du premier module de fixation 6 par rapport au deuxième module de fixation 6' de manière à ce que la distance entre les deux modules de fixation puisse être libre entre une première distance minimum prédéterminée et une deuxième distance maximum prédéterminée. Par une distance libre, on entend ici que l'élève peut rapprocher et éloigner ses patins et donc les deux modules de fixation l'un de l'autre entre un éloignement maximum et un éloignement minimum.The coupling device 2 is designed to allow at least one translation of the first fixing module 6 relative to the second fixing module 6' so that the distance between the two fixing modules can be free between a first minimum distance predetermined distance and a second predetermined maximum distance. By a free distance, it is meant here that the student can bring his skates closer and further apart and therefore the two fixing modules from each other between a maximum distance and a minimum distance.

Cette liberté contrôlée permet de forcer l'élève 5 à maintenir ses patins 8, 8' dans une plage de distance prédéterminée et réglable l'un de l'autre. En variante, dans tous les modes de réalisation, le rapprochement et/ou l'éloignement entre les deux patins 8, et donc entre les deux modules de fixation 6, 6' pourrait se faire par tout autre mouvement qu'une translation, mais de préférence par sensiblement une translation.This controlled freedom makes it possible to force the student 5 to keep his skates 8, 8' within a range of predetermined and adjustable distance from each other. As a variant, in all the embodiments, the bringing together and/or the moving away between the two pads 8, and therefore between the two fixing modules 6, 6' could be done by any movement other than a translation, but of preferably by substantially a translation.

Le dispositif d'accouplement 2 comprend en outre un corps 7 entre les deux éléments de fixation 6, 6'. Préférentiellement, le corps 7 autorise au moins une translation entre les moyens de liaisons 62, 62' des modules de fixations 6,6'.The coupling device 2 further comprises a body 7 between the two fixing elements 6, 6'. Preferably, the body 7 allows at least one translation between the connecting means 62, 62' of the fixing modules 6, 6'.

Le dispositif d'accouplement 2 comprend un corps 7 comprenant une première portion 11 et une deuxième portion 12. Le corps 7 relie le moyen de liaison 62 du premier module de fixation 6 au moyen de liaison 62' du deuxième module de fixation 6'.The coupling device 2 comprises a body 7 comprising a first portion 11 and a second portion 12. The body 7 connects the connecting means 62 of the first fixing module 6 to the connecting means 62' of the second fixing module 6'.

Au moins une, préférentiellement les deux portions 11, 12, comprend une glissière 32, 32' conçue pour recevoir un chariot 33, 33'. Le chariot 33, 33' est donc lié à l'une des portions 11, 12 avec un degré de liberté en translation. En variante, un autre déplacement peut être envisagé, notamment sensiblement une translation.At least one, preferably both portions 11, 12, comprises a slideway 32, 32' designed to receive a carriage 33, 33'. The carriage 33, 33' is therefore linked to one of the portions 11, 12 with a degree of freedom in translation. As a variant, another movement can be envisaged, in particular substantially a translation.

Le chariot 33, 33' est relié à un moyen de liaison 62, 62' d'un module de fixation 6, 6'. La liaison mécanique entre le chariot 33, 33' et le moyen de liaison 62, 62' peut comprendre une liaison mécanique autorisant au moins un degré de liberté en rotation. Préférentiellement, la liaison mécanique entre le chariot 33, 33' et le module de fixation 6, 6' est une liaison rotule, autorisant trois degrés de liberté en rotation. Cette liaison rotule permet, lorsque les patins 8, 8' sont des skis, de ne pas empêcher la prise de carre du skieur.The carriage 33, 33' is connected to a connecting means 62, 62' of a fixing module 6, 6'. The mechanical connection between the carriage 33, 33' and the connection means 62, 62' can comprise a mechanical connection allowing at least one degree of freedom in rotation. Preferably, the mechanical connection between the carriage 33, 33' and the fixing module 6, 6' is a ball joint, allowing three degrees of freedom in rotation. This ball joint makes it possible, when the runners 8, 8' are skis, not to prevent the skier from taking the edge.

Préférentiellement, le chariot 33, 33' comprend une portion conçue pour coopérer avec le moyen de liaison 62 de manière à former une liaison rotule.Preferably, the carriage 33, 33' comprises a portion designed to cooperate with the connecting means 62 so as to form a ball joint.

La glissière 32, 32' peut comprendre au moins une première butée 13, 13' pour bloquer la translation du chariot 33, 33' dans un premier sens. La glissière peut comprendre en outre au moins une deuxième butée 14, 14' pour bloquer la translation du chariot 33, 33' dans un deuxième sens opposé au premier sens.The slide 32, 32' can comprise at least a first stop 13, 13' to block the translation of the carriage 33, 33' in a first direction. The slide can further comprise at least one second stop 14, 14' to block the translation of the carriage 33, 33' in a second direction opposite to the first direction.

Lors du déplacement d'un patin par rapport à l'autre, le chariot 33, 33' suit la glissière entre la première butée 13, 13' et la deuxième butée 14, 14'. Lors du mouvement d'un patin par rapport à l'autre, le chariot 33, 33' peut ainsi se déplacer le long de la glissière 32, 32'entre la première butée 13, 13' et la deuxième butée 14, 14'.During the displacement of one pad relative to the other, the carriage 33, 33' follows the slide between the first stop 13, 13' and the second stop 14, 14'. During the movement of one pad relative to the other, the carriage 33, 33' can thus move along the slideway 32, 32' between the first stop 13, 13' and the second stop 14, 14'.

Lors de l'éloignement des patins, le au moins un chariot 33, 33' glisse le long de la glissière 32, 32' jusqu'à la au moins une première butée 13, 13', définissant une distance maximale entre les moyens de liaison 62, 62' de chaque module de fixation 6, 6'.When the pads are moved away, the at least one carriage 33, 33' slides along the slideway 32, 32' as far as the at least one first stop 13, 13', defining a maximum distance between the connecting means 62, 62' of each fixing module 6, 6'.

À l'inverse, lors du rapprochement des patins, le au moins un chariot 33, 33' glisse le long de la glissière 32, 32' jusqu'à atteindre la au moins une deuxième butée 14, 14', définissant une distance minimale entre les éléments de fixation 6, 6'.Conversely, when the skates are brought together, the at least one carriage 33, 33' slides along the slideway 32, 32' until it reaches the at least one second stop 14, 14', defining a minimum distance between the fixing elements 6, 6'.

Dans un mode de réalisation, la position le long de la glissière d'au moins une butée 13, 13', 14, 14' est réglable.In one embodiment, the position along the slide of at least one stop 13, 13', 14, 14' is adjustable.

La au moins une première butée 13, 13' et / ou la au moins une deuxième butée 14, 14' peuvent être déplacées le long la glissière 32, 32'. Cette amélioration autorise avantageusement à modifier les distances maximum et minimum en fonction des progrès de l'élève et/ou en fonction de l'élève.The at least one first stop 13, 13' and/or the at least one second stop 14, 14' can be moved along the slideway 32, 32'. This improvement advantageously makes it possible to modify the maximum and minimum distances according to the progress of the pupil and/or according to the pupil.

La au moins une deuxième butée peut même être retirée pour régler la distance minimum à environ 0 cm. La première distance minimum et/ou la deuxième distance maximum sont variables en fonction de la position des butées.The at least one second stop can even be removed to set the minimum distance to around 0 cm. The first minimum distance and/or the second maximum distance are variable depending on the position of the stops.

Dans un mode de réalisation, la première distance minimum prédéterminée entre les deux moyens de liaison 62, 62' est comprise entre 0 cm et 35 cm.In one embodiment, the first predetermined minimum distance between the two connecting means 62, 62' is between 0 cm and 35 cm.

Dans un mode de réalisation, la deuxième distance maximum prédéterminée entre les deux moyens de liaison 62, 62' est comprise entre 2 cm et 40 cm.In one embodiment, the second predetermined maximum distance between the two connecting means 62, 62' is between 2 cm and 40 cm.

Dans un mode de réalisation, l'écart entre la première distance minimum et la deuxième distance maximum est comprise entre 2 cm et 40 cm.In one embodiment, the difference between the first minimum distance and the second maximum distance is between 2 cm and 40 cm.

La première distance minimum et la deuxième distance minimum peuvent être réglées en déplaçant une ou plusieurs butées 13, 13', 14, 14' le long de la glissière 32, 32'. Dans un mode de réalisation, les premières butées sont démontables de la glissière de manière à prédéterminer la première distance minimum à 0 cm.The first minimum distance and the second minimum distance can be adjusted by moving one or more stops 13, 13', 14, 14' along the slide 32, 32'. In one embodiment, the first stops are removable from the slideway so as to predetermine the first minimum distance at 0 cm.

Préférentiellement, le corps 7 peut comprendre au moins un moyen de recentrage et/ou d'amortissement pour le blocage progressif du chariot 33, 33' contre la première butée 13, 13' ou contre la deuxième butée 14, 14'.Preferably, the body 7 can comprise at least one recentering and/or damping means for the progressive blocking of the carriage 33, 33' against the first stop 13, 13' or against the second stop 14, 14'.

La première butée 13, 13' et/ou la deuxième butée 14, 14' peuvent comprendre le au moins un moyen de recentrage et d'amortissement 15. La ou les moyens de recentrage et d'amortissement 15 peuvent comprendre un matériau compressible tel une mousse ou un élastomère. La ou les moyens de recentrage et d'amortissement 15 peuvent comprendre un ressort.The first abutment 13, 13' and/or the second abutment 14, 14' can comprise at least one recentering and damping means 15. The recentering and damping means or means 15 can comprise a compressible material such as a foam or an elastomer. The refocusing and damping means 15 may comprise a spring.

Ces moyens de recentrage et d'amortissement 15 permettent avantageusement à l'élève 5 de favoriser le repositionnement des patins au centre de l'écartement prédéfini entre les butée 13, 13' et les butées 14, 14'.These refocusing and damping means 15 advantageously allow the student 5 to favor the repositioning of the skates in the center of the predefined spacing between the stops 13, 13' and the stops 14, 14'.

La fixation entre la première portion 11 et la deuxième portion 12 peut comprendre une fixation cassable ou détachable. Cette fixation de la première portion 11 et de la deuxième portion 12 entre elles est avantageusement une liaison amovible réversible. Particulièrement, cette fixation peut être détachable de manière automatique en cas de contrainte trop importante. Cette fixation permet avantageusement la fixation automatique ou semi-automatique, par exemple assistée, des deux portions 11, 12. Pour cette fixation mutuelle, chaque portion 11, 12 comprend des éléments de connexion correspondants.The attachment between the first portion 11 and the second portion 12 may comprise a frangible or detachable attachment. This attachment of the first portion 11 and the second portion 12 to each other is advantageously a reversible removable connection. Particularly, this fixing can be detachable automatically in case of too much constraint. This fixing advantageously allows the automatic or semi-automatic fixing, for example assisted, of the two portions 11, 12. For this mutual fixing, each portion 11, 12 comprises corresponding connection elements.

Ladite fixation cassable ou détachable selon le mode de réalisation est par exemple conçue pour séparer la première portion 11 de la deuxième portion 12 en cas de choc mécanique supérieur à une contrainte prédéterminée. Cette disjonction du corps 7 permet de limiter certains risques de blessures, par exemple dans le cas où l'élève ne déchausserait qu'un seul pied alors que les deux patins restent reliés par le dispositif.Said breakable or detachable fastener according to the embodiment is for example designed to separate the first portion 11 from the second portion 12 in the event of a mechanical shock greater than a predetermined stress. This disjunction of the body 7 makes it possible to limit certain risks of injury, for example in the case where the pupil would take off only one foot while the two pads remain connected by the device.

Ladite fixation détachable peut comprendre une liaison amovible ou réversible. Par exemple, la fixation détachable peut comprendre un dispositif de fixation de type VELCRO® ou une fermeture par crochets et/ou boucles flexibles.Said detachable attachment may comprise a removable or reversible connection. For example, the detachable attachment may comprise a VELCRO® type attachment device or a closure using flexible hooks and/or loops.

En variante, toute fixation comprenant au moins un aimant peut être mise en œuvre. Ainsi, les éléments de connexion des portions 11, 12 sont conçus pour une liaison mutuelle aimantée, et comprennent pour cela au moins un aimant, voire au moins deux aimants (un aimant chacun ou plus).In the embodiment illustrated in the picture 3 , the binding comprises two magnets 30, 30' on the end of the first portion 11 and of the second portion 12. Alternatively, any binding comprising at least one magnet can be implemented. Thus, the connection elements of the portions 11, 12 are designed for mutual magnetic connection, and for this comprise at least one magnet, or even at least two magnets (one magnet each or more).

Le ou les aimants 30, 30' sont conçus pour être séparés. Cette séparation est obtenue à partir d'une contrainte prédéterminée.The magnet(s) 30, 30' are designed to be separated. This separation is obtained from a predetermined constraint.

Ladite fixation détachable peut comprendre un matériau dont la résistance à la traction est inférieure à 30 MPa.Said detachable fastener may comprise a material whose tensile strength is less than 30 MPa.

La première portion 11 et la deuxième portion 12 peuvent également comprendre des moyens de fixations complémentaires, autrement dit des éléments de connexion, comme des couples mâles / femelles. Ces moyens de fixations ou éléments de connexion complémentaires peuvent comprendre au moins un téton 31 et au moins un trou 31' conçu pour recevoir le téton 31, comme illustré par un deuxième mode de réalisation sur la figure 5. Dans ce mode de réalisation, le au moins un téton 31 et le au moins un trou 31' conçu pour recevoir le téton 31 comprennent les deux aimants 30, 30'.The first portion 11 and the second portion 12 can also comprise complementary fixing means, in other words connection elements, such as male/female couples. These fixing means or complementary connection elements can comprise at least one stud 31 and at least one hole 31' designed to receive the stud 31, as illustrated by a second embodiment on the figure 5 . In this embodiment, the at least one stud 31 and the at least one hole 31' designed to receive the stud 31 comprise the two magnets 30, 30'.

Les figures 9 et 10 illustrent un troisième mode de réalisation d'une liaison amovible aimantée entre une première portion 11 et une deuxième portion 12 d'un corps 7. Dans ce troisième mode de réalisation, le corps 7 comprend une première portion 11 liée au premier module 6, une deuxième portion 12 liée au deuxième module 6', et une troisième portion 27 intermédiaire liée respectivement aux deux premières portions 11, 12. Les deux premières portions 11, 12 forment donc des portions d'extrémité du corps 7.The figures 9 and 10 illustrate a third embodiment of a removable magnetic connection between a first portion 11 and a second portion 12 of a body 7. In this third embodiment, the body 7 comprises a first portion 11 connected to the first module 6, a second portion 12 connected to the second module 6', and a third intermediate portion 27 connected respectively to the first two portions 11, 12. The two first portions 11, 12 therefore form end portions of the body 7.

La troisième portion 27 intermédiaire comprend différentes parties mobiles les unes par rapport aux autres afin de régler la longueur de cette troisième portion 27. Cette construction permet au corps 7 de remplir la fonction de liberté en translation permettant la modification libre de la distance entre les deux éléments de fixation 6, 6' dans une limite prédéfinie. Dans ce mode de réalisation, la troisième portion comprend des cylindres télescopiques coulissants les uns par rapport aux autres. Des butées de réglage sont prévues pour définir l'amplitude de déplacement de chaque cylindre télescopique. Naturellement, tout autre agencement permettant de remplir la même fonction de manière équivalente peut être envisagée en variante.The third intermediate portion 27 comprises various movable parts relative to each other in order to adjust the length of this third portion 27. This construction allows the body 7 to fulfill the function of freedom in translation allowing the free modification of the distance between the two fixing elements 6, 6' within a predefined limit. In this embodiment, the third portion comprises telescopic cylinders sliding relative to each other. Adjustment stops are provided to define the amplitude of movement of each telescopic cylinder. Naturally, any other arrangement making it possible to fulfill the same function in an equivalent manner can be envisaged as a variant.

Chacune des deux premières portions 11, 12 comprend un élément de connexion 41 pour former une liaison amovible avec un élément de connexion 40 correspondant de la troisième portion 27. Cet agencement permet de former deux liaisons identiques entre la troisième portion 27 et respectivement la première portion 11 et la deuxième portion 12. Selon ce mode de réalisation, ces deux liaisons sont amovibles et aimantées. Pour cela, les éléments de connexion 40, 41 mettent en œuvre une fixation mutuelle aimantée. D'autre part, selon ce mode de réalisation, l'élément de connexion 40 de la troisième portion 27 présente une forme tronconique et est un aimant. L'élément de connexion 41 des portions 11, 12 d'extrémité présente une forme creuse correspondante, permettant le logement de l'élément de connexion 40 de forme tronconique mentionné ci-dessus. D'autre part, cette forme creuse est ouverte latéralement, pour permettre le détachement de la forme tronconique, selon une direction particulière prédéfinie, comme cela sera détaillé ci-dessous. Son extrémité est aussi ouverte pour le passage d'une tige de liaison 43 reliant l'élément de connexion 40 tronconique à la troisième portion 27 intermédiaire dans la configuration de fixation. En variante, la deuxième liaison entre la deuxième portion 12 et la troisième portion 27 pourrait être différente, par exemple présenter des éléments de connexion différents, et/ou ne pas être amovible, et/ou ne pas être aimantée.Each of the two first portions 11, 12 comprises a connection element 41 to form a removable connection with a corresponding connection element 40 of the third portion 27. This arrangement makes it possible to form two identical connections between the third portion 27 and respectively the first portion 11 and the second portion 12. According to this embodiment, these two connections are removable and magnetized. For this, the connection elements 40, 41 implement a magnetic mutual attachment. On the other hand, according to this embodiment, the connection element 40 of the third portion 27 has a frustoconical shape and is a magnet. The connection element 41 of the end portions 11, 12 has a corresponding hollow shape, allowing the housing of the connection element 40 of frustoconical shape mentioned above. On the other hand, this hollow shape is open laterally, to allow the detachment of the frustoconical shape, according to a particular predefined direction, as will be detailed below. Its end is also open for the passage of a connecting rod 43 connecting the frustoconical connection element 40 to the third intermediate portion 27 in the fixing configuration. As a variant, the second connection between the second portion 12 and the third portion 27 could be different, for example have different connection elements, and/or not be removable, and/or not be magnetized.

La figure 10 illustre le dispositif d'accouplement 2 selon le troisième mode de réalisation dans une configuration détachée, plus précisément semi détachée. En effet, dans cette configuration, la première portion 11 et la troisième portion 27 intermédiaire sont détachées. Leurs éléments de connexion 40, 41 correspondants ne sont plus en prise. En revanche, la deuxième portion 12 et la troisième portion 27 intermédiaire restent fixées l'une à l'autre. En variante, ces deux portions 12, 27 pourraient aussi être détachées, de manière similaire aux deux portions 11, 27.The figure 10 illustrates the coupling device 2 according to the third embodiment in a detached configuration, more precisely semi-detached. Indeed, in this configuration, the first portion 11 and the third intermediate portion 27 are detached. Their corresponding connection elements 40, 41 are no longer engaged. On the other hand, the second portion 12 and the third intermediate portion 27 remain fixed to each other. Alternatively, these two portions 12, 27 could also be detached, similarly to the two portions 11, 27.

Selon le mode de réalisation, un câble 42 est fixé d'une part à l'élément de connexion 40 de la troisième portion 27 et d'autre part à la première portion 11. Avantageusement, cette première portion 11 intègre un enrouleur automatique, qui permet au câble 42 de se dérouler automatiquement pour augmenter la distance entre les deux portions 11, 27. Toutefois, l'enrouleur exerce une force de rappel sur le câble 42, qui enroule le câble automatiquement si les deux portions 11, 27 se rapprochent, et favorise le rapprochement des deux portions 11, 27, pour assister un utilisateur lors d'une phase de fixation du corps 7. Le même agencement est symétriquement agencé entre la deuxième portion 12 et la troisième portion 27. Naturellement, ce câble 42 reste optionnel et il est possible d'envisager une variante de réalisation sans câble.According to the embodiment, a cable 42 is fixed on the one hand to the connection element 40 of the third portion 27 and on the other hand to the first portion 11. Advantageously, this first portion 11 incorporates an automatic winder, which allows the cable 42 to unwind automatically to increase the distance between the two portions 11, 27. However, the reel exerts a return force on the cable 42, which winds the cable automatically if the two portions 11, 27 come together, and promotes the bringing together of the two portions 11, 27, to assist a user during a fixing phase of the body 7. The same arrangement is symmetrically arranged between the second portion 12 and the third portion 27. Naturally, this cable 42 remains optional and it is possible to envisage an alternative embodiment without cable.

Le fonctionnement de ce troisième mode de réalisation est avantageux. En effet, il permet un détachement convivial du dispositif d'accouplement. Si l'utilisateur souhaite par exemple procéder à une marche avec ses deux patins 8, 8', durant laquelle il n'a plus besoin du support du dispositif d'accouplement 2, il peut facilement procéder au détachement des portions du corps 7 pour atteindre une configuration détachée qui favorise cette marche. L'agencement est tel que ce détachement peut être obtenu automatiquement en positionnant les deux patins 8, 8' dans une position prédéfinie. Dans ce mode de réalisation, il suffit de positionner les deux patins selon des axes parallèles et rapprochés, et avec un pied fortement avancé par rapport à l'autre. Cette position des patins permet de positionner le corps 7 du dispositif d'accouplement 2 dans une direction sensiblement parallèle aux deux patins 8, 8'. Dans cette direction, les éléments de connexion 40, 40' se séparent automatiquement. En remarque complémentaire, en cas de chute de l'utilisateur, les efforts exercés sur le corps 7 présentent une amplitude suffisante pour dépasser la force magnétique de la liaison aimantée. De plus, la direction des forces exercées est sensiblement aléatoire et finit par atteindre la direction de détachement. Par conséquent, la solution permet aussi le détachement automatique des portions du corps 7 lors d'une chute, au-delà d'une contrainte exercée, pour atteindre la mise en sécurité de l'utilisateur.The operation of this third embodiment is advantageous. Indeed, it allows user-friendly detachment of the coupling device. If the user wishes for example to proceed with a walk with his two skates 8, 8', during which he no longer needs the support of the coupling device 2, he can easily detach the portions of the body 7 to reach a detached configuration that favors this walk. The arrangement is such that this detachment can be obtained automatically by positioning the two pads 8, 8' in a predefined position. In this embodiment, it suffices to position the two pads along parallel and close axes, and with one foot greatly advanced relative to the other. This position of the pads makes it possible to position the body 7 of the coupling device 2 in a direction substantially parallel to the two pads 8, 8'. In this direction, the connecting elements 40, 40' separate automatically. As a further remark, in the event of the user falling, the forces exerted on the body 7 have a sufficient amplitude to exceed the magnetic force of the magnetic connection. In addition, the direction of the forces exerted is substantially random and eventually reaches the direction of detachment. Therefore, the solution also allows the detachment automatic portions of the body 7 during a fall, beyond a constraint exerted, to achieve the safety of the user.

En complément, le troisième mode de réalisation permet de plus d'assister l'utilisateur à la fixation des différentes portions du corps 7, pour passer de la configuration détachée à la configuration attachée. En effet, l'utilisateur peut repositionner ses patins en alignement tel que décrit pour le détachement, puis les rapprocher de sorte que le ou les câbles 42 s'enroulent automatiquement complètement, guidant dans le même temps le rapprochement des éléments de connexion 40, 40'. Lorsque ces derniers sont suffisamment proches, la forme magnétique des aimants suffit à leur rapprochement final en configuration de fixation. La solution selon ce mode de réalisation permet ainsi de mettre en œuvre un détachement et une fixation automatiques d'au moins deux portions du corps 7.In addition, the third embodiment also makes it possible to assist the user in fixing the various portions of the body 7, to pass from the detached configuration to the attached configuration. Indeed, the user can reposition his pads in alignment as described for the detachment, then bring them closer together so that the cable or cables 42 automatically wrap completely, guiding at the same time the bringing together of the connection elements 40, 40 '. When the latter are close enough, the magnetic shape of the magnets is sufficient for their final rapprochement in the fixing configuration. The solution according to this embodiment thus makes it possible to implement an automatic detachment and attachment of at least two portions of the body 7.

Selon un mode de réalisation, il existe donc un positionnement particulier du dispositif d'accouplement 2, particulièrement de la position relative des deux modules de fixation 6, 6', qui autorise le détachement ou la fixation d'au moins deux portions séparables par une liaison amovible. Ce positionnement particulier permet donc le passage de la configuration détachée à la configuration de fixation et inversement. Les autres positionnements du dispositif d'accouplement 2, particulièrement de la position relative des deux modules de fixation 6, 6', n'autorisent pas ce changement de configuration.According to one embodiment, there is therefore a particular positioning of the coupling device 2, particularly of the relative position of the two fixing modules 6, 6', which allows the detachment or the fixing of at least two separable portions by a removable link. This particular positioning therefore allows the transition from the detached configuration to the attachment configuration and vice versa. The other positions of the coupling device 2, particularly of the relative position of the two fixing modules 6, 6', do not allow this change of configuration.

Les différents modes de réalisation décrits précédemment pourraient naturellement être combinés pour former d'autres modes de réalisation. Par exemple, un câble et un enrouleur pourraient aussi être agencés dans les solutions des modes de réalisation des figures 3, 4 et 5. Les éléments de connexion pourraient prendre d'autres formes sans sortir du cadre de l'invention. Ils pourraient mettre en œuvre une liaison aimantée, comme décrit, ou non aimantée, mais par exemple simplement clippée. De plus, le corps 7 peut comprendre deux, trois ou plus portions indépendantes, mobiles l'une par rapport à l'autre, notamment détachable pour former une liaison amovible du dispositif d'accouplement 2.The different embodiments described previously could naturally be combined to form other embodiments. For example, a cable and a reel could also be arranged in the solutions of the embodiments of the figures 3, 4 and 5 . The connection elements could take other forms without departing from the scope of the invention. They could implement a magnetic link, like described, or not magnetized, but for example simply clipped. In addition, the body 7 may comprise two, three or more independent portions, movable relative to each other, in particular detachable to form a removable connection of the coupling device 2.

Un mode de réalisation non-représenté, la première portion et la deuxième portion peuvent comprendre des tubes concentriques coulissant l'un dans l'autre. Chaque portion est alors fixée à un module de fixation par une liaison mécanique ne comprenant pas de degrés de liberté en translation. La première portion peut coulisser le long de la deuxième portion entre une première butée bloquant la translation des deux portions dans un premier sens et une deuxième butée bloquant la translation des deux portions dans un deuxième sens opposé au premier sens.An embodiment not shown, the first portion and the second portion may comprise concentric tubes sliding one inside the other. Each portion is then fixed to a fixing module by a mechanical connection comprising no degrees of freedom in translation. The first portion can slide along the second portion between a first stop blocking the translation of the two portions in a first direction and a second stop blocking the translation of the two portions in a second direction opposite to the first direction.

La distance entre les deux modules de fixation varie alors entre une distance maximum et une distance minimum quand la première portion est bloquée respectivement par la première butée et la deuxième butée.The distance between the two fixing modules then varies between a maximum distance and a minimum distance when the first portion is blocked respectively by the first stop and the second stop.

Dans un mode de réalisation, le brin de guidage 3 est destiné à être fixé au module de fixation 6.In one embodiment, the guide strand 3 is intended to be fixed to the fixing module 6.

Le brin de guidage 3 comprend préférentiellement au moins une première portion élastique 9. La au moins une portion élastique 9 permet d'amortir les chocs lorsque le brin 3 est mis sous tension. Cette portion élastique 9 permet avantageusement à l'élève 5 de moins ressentir les à-coups. Les à-coups peuvent en effet être source de déséquilibre, par exemple lorsqu'il y a un différentiel de vitesse entre le moniteur et l'élève et que le brin de guidage 3 se retend. Le brin de guidage 3 comprend de plus avantageusement au moins une portion munie de franges 9' conçue pour augmenter sa visibilité.The guide strand 3 preferably comprises at least a first elastic portion 9. The at least one elastic portion 9 allows shock absorption when the strand 3 is put under tension. This elastic portion 9 advantageously allows the pupil 5 to feel the jolts less. Jolts can in fact be a source of imbalance, for example when there is a speed differential between the instructor and the student and that the guide strand 3 tightens. The guide strand 3 more advantageously comprises at least one portion provided with fringes 9' designed to increase its visibility.

Préférentiellement, la portion élastique 9 permet l'amortissement élastique des chocs en cas de tension mécanique sur le brin de guidage 3 jusqu'à une contrainte prédéterminée.Preferably, the elastic portion 9 allows the elastic damping of shocks in the event of mechanical tension on the guide strand 3 up to a predetermined constraint.

Said breakable or detachable portion 10 is designed to separate the guide strand 3 into two parts in the event of mechanical tension greater than a predetermined stress. The two parts are the parts located on one side and on the other of said breakable or detachable portion 10.

Ladite portion cassable ou détachable 10 peut comprendre un matériau dont la résistance à la traction est inférieure à 20 MPa.Said frangible or detachable portion 10 may comprise a material whose tensile strength is less than 20 MPa.

Ladite portion cassable ou détachable 10 peut comprendre une liaison amovible, ladite liaison étant apte à céder en cas de tension supérieure à une contrainte donnée. Préférentiellement, ladite liaison amovible est réversible. Par exemple, la liaison amovible peut comprendre un dispositif de fixation de type VELCRO® ou une fermeture par crochets et/ou boucles flexibles. Ladite liaison amovible peut également comprendre deux aimants conçus pour être séparés à partir d'une contrainte prédéterminée.Said breakable or detachable portion 10 may comprise a removable link, said link being capable of yielding in the event of tension greater than a given constraint. Preferably, said removable connection is reversible. For example, the removable connection may comprise a VELCRO ® type fastening device or a closure using flexible hooks and/or loops. Said removable link can also comprise two magnets designed to be separated from a predetermined constraint.

Dans un mode de réalisation, la portion élastique 9 comprend un matériau dont la limite d'élasticité est supérieure à la contrainte nécessaire pour faire céder la liaison de ladite portion cassable ou détachable 10.In one embodiment, the elastic portion 9 comprises a material whose elastic limit is greater than the stress necessary to break the connection of said breakable or detachable portion 10.

Ainsi, en cas d'accident ou si un brin de guidage 3 se prend dans un obstacle, le brin de guidage 3 se détache en deux parties. Le patin 8 de l'élève 5 n'est alors plus relié mécaniquement au moniteur 4.Thus, in the event of an accident or if a guide strand 3 gets caught in an obstacle, the guide strand 3 comes off in two parts. Skate 8 of student 5 is then no longer mechanically connected to monitor 4.

Dans un mode de réalisation, chaque brin de guidage 3 comprend un enrouleur automatique 17. L'enrouleur automatique 17 est conçu pour être porté dans la main du moniteur 4. L'enrouleur automatique 17 permet avantageusement d'enrouler le brin de guidage 3 sur lui-même, permettant ainsi au moniteur 4 de régler la distance du brin de guidage 3 entre lui et l'élève 5.In one embodiment, each guide strand 3 comprises an automatic winder 17. The automatic winder 17 is designed to be carried in the hand of the monitor 4. The automatic winder 17 advantageously makes it possible to wind the guide strand 3 on himself, thus allowing the monitor 4 to adjust the distance of the guide strand 3 between him and the pupil 5.

Préférentiellement, l'enrouleur automatique 17 comprend une gâchette 18 conçue pour déclencher l'enroulage automatique du brin et/ou le déroulage automatique du brin de guidage 3.Preferably, the automatic winder 17 comprises a trigger 18 designed to trigger the automatic winding of the strand and/or the automatic unwinding of the guide strand 3.

L'enrouleur automatique 17 peut comprendre un moyen pour rester à proximité du poignet du moniteur si ce dernier le lâche. Ledit moyen peut comprendre une sangle attachée à l'enrouleur 17 et destinée à être passée autour du coup ou du poignet du moniteur. La sangle peut également être destinée à être attachée à la combinaison du moniteur, préférentiellement au niveau de la manche.The automatic retractor 17 may comprise a means of remaining close to the wrist of the monitor if the latter releases it. Said means may comprise a strap attached to the winder 17 and intended to be passed around the monitor's neck or wrist. The strap can also be intended to be attached to the monitor's suit, preferably at the level of the sleeve.

Dans un mode de réalisation illustré sur la figure 7, le système d'aide à l'apprentissage 1 comprend une puce GPS 20 et des moyens de transmission 21 pour transmettre des informations de positions et de déplacement à un système électronique 22 à proximité. L'appareil électronique 22 est préférentiellement un téléphone portable.In one embodiment illustrated in the figure 7 , the learning aid system 1 comprises a GPS chip 20 and transmission means 21 for transmitting position and displacement information to an electronic system 22 nearby. The electronic device 22 is preferably a mobile phone.
