Abstract

The boot retainer consists of a base (4) which is fixed to the snow board surface and receives the sole of the boot. A rear support (5) is articulated to the base so that it can pivot in an anterio-posterior direction. The rear support and base are connected by a spring-loaded member with at least one spring (12) to apply an upward pressure to the support in relation to the base. The rear support (5) can be made in one piece or in the form of an upper curved shell and a separate lower arch which is articulated to the base. The spring-loaded member connecting the rear support to the base also incorporates a stop to limit the rearward movement of the support. In a variant of the design the spring can be in the form of a torsion spring with its ends connected to the support and base.

Description

Dispositif de retenue d'une chaussure sur une planche de glisse destinée à la pratique du surf.Device for retaining a shoe on a sliding board intended for the practice of surfing.

L'invention se rapporte au domaine des moyens de retenue d'une chaussure sur une planche de glisse destinée à la pratique du surf sur neige. L'invention concerne plus particulièrement des moyens de retenue d'une chaussure qui permet des mouvements de flexion ou d'inclinaison de la jambe par rapport au pied d'un utilisateur.The invention relates to the field of means for retaining a shoe on a gliding board intended for the practice of snowboarding. The invention relates more particularly to means for retaining a shoe which allows movements of flexion or inclination of the leg relative to the foot of a user.

Dans la pratique du surf de neige, l'utilisateur conduit sa planche sur des trajectoires qui peuvent être sensiblement droites ou courbes. Dans tous les cas, la conduite ne peut être précise que si les appuis de la planche sur la neige sont contrôlés par l'utilisateur.In the practice of snowboarding, the user drives his board on paths which can be substantially straight or curved. In all cases, driving can only be precise if the support of the board on the snow is controlled by the user.

L'expérience montre que le contrôle des appuis se fait bien quand les trajectoires sont relativement droites, mais que le contrôle est délicat ou même impossible lorsque les trajectoires sont courbes.Experience shows that the control of the supports is done well when the trajectories are relatively straight, but that the control is delicate or even impossible when the trajectories are curved.

En effet, l'utilisateur est toujours amené à faire des mouvements avec le corps et les membres pour gérer son équilibre en même temps qu'il conduit la planche. Il s'avère très difficile de coordonner parfaitement la gestion de l'équilibre et la conduite de la planche dans les trajectoires courbes, en virage ou sur une bosse.Indeed, the user is always required to make movements with the body and the limbs to manage his balance at the same time as he is driving the board. It turns out to be very difficult to perfectly coordinate the management of balance and the handling of the board in curved trajectories, in turns or on a bump.

En fait, les mouvements faits pour conserver l'équilibre perturbent le contrôle des appuis nécessaire à une conduite précise. En particulier, lorsque l'utilisateur fléchit et incline les jambes pour conserver l'équilibre, il ne peut éviter en même temps de provoquer un changement d'inclinaison parfois brutal de la planche par rapport au sol.In fact, the movements made to maintain balance disturb the support control necessary for precise driving. In particular, when the user flexes and tilts his legs to maintain balance, he cannot at the same time avoid causing a change in the sometimes abrupt inclination of the board relative to the ground.

Ce changement d'inclinaison a généralement pour effet de modifier brutalement la surface de contact de la planche sur le sol. Par suite, la conduite est perturbée et le contrôle de la trajectoire est aléatoire, parce que les forces de réaction du sol sur la planche varient dans des proportions considérables.This change in inclination generally has the effect of suddenly modifying the contact surface of the board on the ground. As a result, the driving is disturbed and the trajectory control is random, because the reaction forces of the ground on the board vary in considerable proportions.

Ce phénomène se vérifie particulièrement lorsque l'utilisateur a besoin de garder l'équilibre et d'appuyer vers le sol avec le côté de la planche situé dans son dos.This phenomenon is particularly true when the user needs to keep his balance and to press towards the ground with the side of the board located behind his back.

L'art antérieur a proposé des dispositifs qui donnent une certaine souplesse de positionnement entre chaque pied et la planche.The prior art has proposed devices which give a certain flexibility of positioning between each foot and the board.

C'est par exemple le cas du document FR 2 650 752 dont le but est de permettre à l'utilisateur de se placer dans la position la plus confortable et la plus équilibrée au cours des évolutions, grâce à des articulations souples disposées entre les pieds et la planche. Le dispositif selon le document FR 2 650 752 ne permet cependant pas à l'utilisateur de gérer les variations d'appui. En effet, la souplesse des articulations ne favorise pas un guidage précis et ne permet pas à l'utilisateur d'identifier correctement les informations sensorielles qu'il reçoit. Par conséquent, ce dispositif n'est pas réellement satisfaisant et la maîtrise des trajectoires courbes est difficile, voire impossible.This is for example the case of document FR 2 650 752, the aim of which is to allow the user to place himself in the most comfortable and balanced position during the changes, thanks to flexible joints arranged between the feet. and the board. The device according to document FR 2 650 752 does not, however, allow the user to manage the support variations. Indeed, the flexibility of the joints does not favor precise guidance and does not allow the user to correctly identify the sensory information he receives. Therefore, this system is not really satisfactory and control of curved trajectories is difficult, if not impossible.

Le document DE 89 02 125 propose un dispositif de retenue d'une chaussure sur une planche comprenant une coquille articulée sur une embase selon un axe transversal. L'articulation permet un plage du dispositif pour le transport. Un moyen élastique amovible est apte à maintenir la coquille par rapport à l'embase dans une position d'utilisation. Le moyen élastique agit pour limiter un mouvement de flexion du bas de jambe vers le pied. Il s'ensuit que l'utilisateur peut facilement prendre des appuis avec l'avant du pied.Document DE 89 02 125 proposes a device for retaining a shoe on a board comprising a shell articulated on a base along a transverse axis. The articulation allows a range of the device for transport. A removable elastic means is able to hold the shell relative to the base in a position of use. The elastic means acts to limit a flexion movement from the lower leg to the foot. It follows that the user can easily take support with the forefoot.

Par contre, il n'est pas possible à l'utilisateur de maîtriser facilement des trajectoires courbes à cause de l'élasticité du dispositif. En particulier, il est pratiquement impossible de garder une trajectoire courbe choisie dans le cas où il faut gérer à la fois l'équilibre et une prise d'appui au sol avec le côté de la planche situé dans le dos de l'utilisateur.On the other hand, it is not possible for the user to easily master curved trajectories because of the elasticity of the device. In particular, it is practically impossible to keep a curved trajectory chosen in the case where it is necessary to manage both the balance and a grip on the ground with the side of the board located behind the user's back.

L'invention a pour but de remédier aux inconvénients ci-avant énumérés. Pour ce faire, elle propose un dispositif de retenue d'une chaussure sur une planche de glisse, le dispositif comprenant notamment un élément d'appui dorsal pour assurer l'appui arrière du bas de jambe et une embase destinée à recevoir la semelle de la chaussure, l'élément d'appui dorsal étant articulé sur l'embase selon un axe Y-Y' sensiblement transversal du dispositif.The object of the invention is to remedy the drawbacks listed above. To do this, it proposes a device for retaining a boot on a gliding board, the device notably comprising a back support element for ensuring the rear support of the lower leg and a base intended to receive the sole of the shoe, the back support element being articulated on the base along a substantially transverse axis YY 'of the device.

L'invention est caractérisée par le fait qu'au moins un moyen élastique sollicite l'élément d'appui dorsal par rapport à l'embase selon un mouvement d'articulation selon l'axe Y-Y' dans un sens de flexion du bas de jambe vers le pied ou postéro-antérieur.The invention is characterized in that at least one elastic means biases the dorsal support element relative to the base according to an articulation movement along the axis YY 'in a direction of flexion of the lower leg towards the foot or postero-anterior.

Cette structure permet en fait aux membres inférieurs de pouvoir s'incliner par rapport à la planche de façon que l'élément d'appui dorsal reste en contact permanent avec le bas de jambe, quelle que soit la trajectoire de la planche. Il s'ensuit que l'utilisateur peut percevoir des informations sensorielles de façon continue.This structure in fact allows the lower limbs to be able to tilt relative to the board so that the back support element remains in permanent contact with the lower leg, whatever the trajectory of the board. It follows that the user can perceive sensory information continuously.

Selon un mode de réalisation, l'invention est caractérisée par le fait que l'élément d'appui dorsal est monobloc. Cette structure confère au dispositif une rigidité latérale par rapport au pied qui convient à une conduite en virage.According to one embodiment, the invention is characterized in that the back support element is in one piece. This structure gives the device a lateral stiffness with respect to the foot which is suitable for cornering.

Selon un autre mode de réalisation, l'invention est caractérisée par le fait que l'élément d'appui dorsal comprend une coquille et un arceau articulés l'un par rapport à l'autre selon un axe X-X' situé dans un plan sensiblement longitudinal du dispositif. Cette structure donne au dispositif un degré de liberté latérale du bas de jambe par rapport au pied qui convient à l'exécution de figures de style.According to another embodiment, the invention is characterized in that the back support element comprises a shell and a hoop articulated relative to each other along an axis XX 'situated in a substantially longitudinal plane of the device. This structure gives the device a degree of lateral freedom of the lower leg relative to the foot which is suitable for the execution of figures of style.

L'invention est également caractérisée par le fait qu'un moyen d'arrêt limite le mouvement d'articulation de l'élément d'appui dorsal par rapport à l'embase selon l'axe Y-Y' dans un sens d'extension du bas de jambe par rapport au pied ou sens antéro-postérieur.The invention is also characterized in that a stop means limits the articulation movement of the back support element relative to the base according to the axis YY 'in a direction of extension of the lower leg relative to the foot or anteroposterior direction.

Par conséquent, l'utilisateur peut prendre sur le sol un appui arrière rigide quand il ne doit pas changer brutalement son équilibre.Consequently, the user can take a rigid rear support on the ground when he must not suddenly change his balance.

Une variante de réalisation du dispositif selon l'invention est caractérisée en ce que le moyen élastique est un ressort de compression dont une extrémité sollicite l'élément d'appui dorsal et dont l'autre extrémité sollicite l'embase, dans un sens d'éloignement.An alternative embodiment of the device according to the invention is characterized in that the elastic means is a compression spring, one end of which urges the back support element and the other end of which urges the base, in a direction of remoteness.

L'avantage est que le ressort élimine les cales de neige.The advantage is that the spring eliminates the snow wedges.

Une autre variante de réalisation de l'invention est caractérisée par le fait que le moyen élastique est un ressort de torsion dont une extrémité est liée à l'élément d'appui dorsal et dont l'autre extrémité est liée à l'embase. Cette variante de réalisation présente l'avantage d'un faible encombrement.Another alternative embodiment of the invention is characterized in that the elastic means is a torsion spring, one end of which is linked to the back support element and the other end of which is linked to the base. This alternative embodiment has the advantage of a small footprint.

D'autres caractéristiques et avantages de l'invention seront mieux compris à l'aide de la description qui va suivre, en regard du dessin annexé illustrant, par des exemples non limitatifs, comment l'invention peut être réalisée et dans lequel :

Other characteristics and advantages of the invention will be better understood with the aid of the description which follows, with reference to the appended drawing illustrating, by non-limiting examples, how the invention can be implemented and in which:
  • FIG. 1 is a perspective view of a gliding board with two retaining devices according to one embodiment,

  • FIG. 6 is a section on VI-VI of FIG. 5.

Les figures 1 et 1a montrent une planche de glisse 1 sur le dessus de laquelle sont fixés deux dispositifs de retenue 2 des chaussures 3 d'un utilisateur. Chaque dispositif 2 comprend une embase 4 pour le maintien du pied et un élément d'appui dorsal 5 pour prendre appui notamment dans les virages où l'utilisateur s'appuie sur la carre arrière et a le dos face à la pente. Les dispositifs 2 sont orientés respectivement dans une direction sensiblement transversale de la planche 1, de façon que les extrémités des pieds soient proches d'un côté longitudinal frontal 6, et que les talons soient proches d'un côté longitudinal dorsal 7 de la planche 1.Figures 1 and 1a show a gliding board 1 on top of which are fixed two retaining devices 2 of the shoes 3 of a user. Each device 2 comprises a base 4 for maintaining the foot and a back support element 5 for taking support, in particular when cornering where the user leans on the rear edge and has his back facing the slope. The devices 2 are oriented respectively in a substantially transverse direction of the board 1, so that the ends of the feet are close to a longitudinal front side 6, and the heels are close to a longitudinal dorsal side 7 of the board 1 .

Chaque dispositif 2 comprend des moyens de retenue de la chaussure 3 sur le dispositif 2, représentés sous la forme de sangles 8, 9, 10, deux sangles 8, 9 maintenant la chaussure 3 sur l'embase 4 au niveau du pied, et une sangle 10 maintenant la chaussure 3 sur l'élément d'appui dorsal 5 au niveau du bas de jambe.Each device 2 comprises means for retaining the boot 3 on the device 2, represented in the form of straps 8, 9, 10, two straps 8, 9 holding the boot 3 on the base 4 at foot level, and a strap 10 now the shoe 3 on the back support element 5 at the lower leg.

Sur chaque dispositif 2, l'élément d'appui dorsal 5 est articulé par rapport à l'embase 4 par un moyen d'articulation, représenté ici sous la forme de rivets 11, de façon que l'élément d'appui dorsal 5 puisse pivoter par rapport à l'embase 4 autour d'un axe Y-Y' sensiblement transversal du dispositif 2. L'axe Y-Y' est transversal par rapport à une direction longitudinale du dispositif 2 s'étendant sensiblement des doigts vers le talon du pied.On each device 2, the back support element 5 is articulated relative to the base 4 by an articulation means, shown here in the form of rivets 11, so that the back support element 5 can pivot relative to the base 4 around a substantially transverse axis YY 'of the device 2. The axis YY' is transverse with respect to a longitudinal direction of the device 2 extending substantially from the fingers towards the heel of the foot.

Conformément à l'esprit de l'invention, un moyen élastique sollicite l'élément d'appui dorsal 5 par rapport à l'embase 4 selon un mouvement de rotation par rapport à l'axe Y-Y' dans un sens de flexion du bas de jambe vers le pied. Ce moyen élastique peut être un ressort de compression 12 visible sur les figures 1, 1a, 2, 3, 4.In accordance with the spirit of the invention, an elastic means biases the back support element 5 relative to the base 4 according to a rotational movement relative to the axis YY ′ in a direction of bending from the bottom of leg towards the foot. This elastic means can be a compression spring 12 visible in FIGS. 1, 1a, 2, 3, 4.

Selon diverses variantes de réalisation, sans changer l'esprit de l'invention, la sollicitation exercée par le moyen élastique peut être permanente ou temporaire.According to various variant embodiments, without changing the spirit of the invention, the stress exerted by the elastic means can be permanent or temporary.

Comme le montre la figure 4, le ressort 12 est guidé par une barre 13 de section cylindrique. Le ressort 12 prend appui par l'une de ses extrémités sur une coupelle 14 solidarisée à la barre 13 par tout moyen convenable tel qu'une soudure 15. Le ressort 12 prend appui par l'autre extrémité sur un bouchon 16 lui-même fixé sur un fourreau 17, par exemple au moyen d'un filetage 18. Le bouchon 16 est percé en son centre par un trou alésé 19 qui sert à guider la tige 13 dans une direction de compression ou d'extension du ressort 12. Le fourreau 17 est prolongé à son extrémité opposée au bouchon 16 par un plat 20 percé d'un trou 21 d'axe 22. La barre 13 est prolongée à son extrémité sortant par le trou alésé 19 par un plat 23 percé d'un trou 24 d'axe 25.As shown in Figure 4, the spring 12 is guided by a bar 13 of cylindrical section. The spring 12 is supported by one of its ends on a cup 14 secured to the bar 13 by any suitable means such as a weld 15. The spring 12 is supported by the other end on a plug 16 itself fixed on a sheath 17, for example by means of a thread 18. The plug 16 is pierced in its center by a reamed hole 19 which serves to guide the rod 13 in a direction of compression or extension of the spring 12. The sheath 17 is extended at its end opposite to the plug 16 by a flat 20 pierced with a hole 21 with an axis 22. The bar 13 is extended at its end exiting by the reamed hole 19 by a flat 23 pierced with a hole 24 d axis 25.

La barre 13 est donc apte à pénétrer dans le fourreau 17 contre l'action du ressort 12 en étant guidée dans le fourreau 17 par le trou alésé 19 du bouchon 16.The bar 13 is therefore able to penetrate into the sheath 17 against the action of the spring 12 while being guided in the sheath 17 by the reamed hole 19 of the plug 16.

Dans la pratique, comme le montrent les figures 1 et 1a, le fourreau 17 est articulé par l'axe 22 commun à une goupille 26, au trou 21 du plat 20, et à deux orifices d'un socle 27, sur l'élément d'appui dorsal 5.In practice, as shown in FIGS. 1 and 1a, the sleeve 17 is articulated by the axis 22 common to a pin 26, to the hole 21 of the plate 20, and to two orifices of a base 27, on the element back support 5.

La barre 13 est elle articulée par l'axe 25 commun a une goupille 28, au trou 24 du plat 23, et à deux orifices d'un socle 29, sur l'embase 4.The bar 13 is articulated by the axis 25 common to a pin 28, to the hole 24 of the plate 23, and to two orifices of a base 29, on the base 4.

Comme le ressort 12 sollicite la coupelle 14 et le bouchon 16 dans un sens d'éloignement, l'élément d'appui dorsal 5 et l'embase 4 sont sollicités dans le sens d'une flexion de la chaussure 3.As the spring 12 urges the cup 14 and the plug 16 in a direction of separation, the back support element 5 and the base 4 are urged in the direction of flexion of the shoe 3.

Comme le montre la figure 4, un moyen d'arrêt du déplacement de l'élément d'appui dorsal 5 par rapport à l'embase 4 dans un sens d'extension du pied est réalisé par exemple par l'association du fond 35 du fourreau et du bout 36 de la barre 13. Lorsque le fond 35 et le bout 36 sont en contact, le ressort 12 est dans un état de compression maximale.As shown in Figure 4, a means of stopping the movement of the back support element 5 relative to the base 4 in a direction of extension of the foot is achieved for example by the association of the bottom 35 of the scabbard and tip 36 of the bar 13. When the bottom 35 and the end 36 are in contact, the spring 12 is in a state of maximum compression.

Ainsi réalisé, le dispositif de retenue 2 permet à un utilisateur de fléchir rapidement et facilement les jambes tout en sollicitant le côté longitudinal dorsal 7 de la planche 1 vers le sol, grâce à l'action du ressort 12. Par suite un contact est réalisé entre le côté dorsal 7 et le sol dans les virages ou sur les bosses où l'utilisateur a le dos face à la pente du terrain. Les mouvements du corps et des jambes faits pour conserver l'équilibre ne perturbent donc pas la conduite de la planche 1.Thus produced, the retaining device 2 allows a user to flex the legs quickly and easily while stressing the dorsal longitudinal side 7 of the board 1 towards the ground, thanks to the action of the spring 12. As a result, contact is made between the dorsal side 7 and the ground in turns or on bumps where the user has his back facing the slope of the terrain. The movements of the body and legs made to maintain balance therefore do not disturb the handling of board 1.

Bien entendu, toutes les techniques et tous les matériaux connus pourront être utilisés pour réaliser l'invention.Of course, all known techniques and materials can be used to carry out the invention.

En particulier, on peut prévoir de faire le fourreau en métal tel que l'aluminium ou en matériaux plastiques et composites. Le bouchon 16 pourrait être en bronze, la barre 13 en acier, le ressort 12 en acier allié.In particular, provision can be made to make the metal sheath such as aluminum or plastic and composite materials. The plug 16 could be made of bronze, the bar 13 made of steel, the spring 12 made of alloy steel.

Deux variantes du mode de réalisation décrit apparaissent en vue latérale sur les figures 2 et 3.Two variants of the embodiment described appear in side view in FIGS. 2 and 3.

Sur la figure 2, l'élément d'appui dorsal 5 comprend une coquille 37 et un arceau 38 formant un seul bloc, obtenu par exemple en matière plastique injectée.In FIG. 2, the back support element 5 comprises a shell 37 and a hoop 38 forming a single block, obtained for example from injected plastic.

Sur la figure 3, l'élément d'appui dorsal 5 comprend une coquille 39 articulée sur un arceau 40 selon un axe X-X' sensiblement longitudinal de la chaussure ; l'articulation peut se faire grâce à un rivet ou tout autre moyen et facilite des inclinaisons latérales du bas de jambe, selon l'axe X-X'.In FIG. 3, the back support element 5 comprises a shell 39 articulated on a hoop 40 along an axis XX ′ substantially longitudinal of the shoe; the articulation can be done using a rivet or any other means and facilitates lateral inclinations of the lower leg, along the axis XX '.

Pour ces deux variantes de réalisation, l'esprit de l'invention est inchangé. En effet, le ressort 12 sollicite toujours le bas de jambe en flexion par rapport au pied dans le sens de la flèche F, en agissant entre l'arceau 38 ou 40 et l'embase 4 dans un sens d'éloignement respectif.For these two variant embodiments, the spirit of the invention is unchanged. Indeed, the spring 12 always biases the lower leg in flexion relative to the foot in the direction of the arrow F, acting between the arch 38 or 40 and the base 4 in a respective direction of separation.

Un autre mode de réalisation de l'invention est proposé à l'aide des figures 5 et 6. Pour des raisons de commodité, les mêmes pièces sont désignées par les mêmes références.Another embodiment of the invention is proposed using FIGS. 5 and 6. For reasons of convenience, the same parts are designated by the same references.

On retrouve un élément d'appui dorsal 5 comprenant une coquille 37 et un arceau 38 articulés sur une embase 4 selon un axe sensiblement transversal Y-Y'.There is a back support element 5 comprising a shell 37 and a hoop 38 articulated on a base 4 along a substantially transverse axis Y-Y '.

Comme le montre la coupe de la figure 6, un ressort de torsion 41 agit entre l'embase 4 et l'arceau 38 pour solliciter l'arceau 38 et maintenir le contact entre la chaussure 3 et la coquille 37. En effet, des extrémités 42 et 43 du ressort 41 sont solidarisées respectivement à l'embase 4 et à l'arceau 38 en passant dans des trous de l'embase 4 et de l'arceau 38. Le ressort 41 reste en place grâce à la sollicitation permanente d'une rondelle élastique 44 qui est intercalée entre l'embase 4 et un épaulement 45 d'un rivet 46 d'axe Y-Y'.As shown in the section of FIG. 6, a torsion spring 41 acts between the base 4 and the arch 38 to urge the arch 38 and maintain contact between the shoe 3 and the shell 37. In fact, the ends 42 and 43 of the spring 41 are secured respectively to the base 4 and to the arch 38 passing through holes in the base 4 and the arch 38. The spring 41 remains in place thanks to the permanent stress on an elastic washer 44 which is interposed between the base 4 and a shoulder 45 of a rivet 46 of axis Y-Y '.

Le rivet 46 sert à maintenir l'un par rapport à l'autre l'embase 4 et l'arceau 38.The rivet 46 serves to hold the base 4 and the arch 38 relative to each other.

En fonctionnement, un déplacement de l'arceau 38 par rapport à l'embase 4 dans le sens de la flèche F de la figure 5 est rapide et facile.In operation, a movement of the arch 38 relative to the base 4 in the direction of arrow F in Figure 5 is quick and easy.

Le mouvement de l'arceau 38 et de la coquille 37 dans le sens inverse de la flèche F est limité par une butée 56 qui s'appuie sur une face 57 de l'embase 4. Les effets techniques de ce mode de réalisation de l'invention sont identiques à ceux du premier mode.The movement of the arch 38 and the shell 37 in the opposite direction to the arrow F is limited by a stop 56 which rests on one face 57 of the base 4. The technical effects of this embodiment of the invention are identical to those of the first mode.

On pourra prévoir de réaliser le ressort 41 en métal ou alliage métallique. Le rivet 46, l'embase 4 et l'arceau 38 pourront être faits en métal ou en matière synthétique mise en forme par tout moyen connu comme l'injection ou l'usinage.Provision may be made to produce the spring 41 in metal or a metal alloy. The rivet 46, the base 4 and the arch 38 can be made of metal or of synthetic material shaped by any known means such as injection or machining.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation ainsi décrits et comprend tous les équivalents techniques pouvant entrer dans l'étendue des revendications qui vont suivre.Of course, the invention is not limited to the embodiments thus described and includes all the technical equivalents which may fall within the scope of the claims which will follow.

En particulier, on peut imaginer de supprimer les sangles 8, 9, 10 et de les remplacer par tout système de chaussage automatique pouvant s'intercaler entre la chaussure 3 et l'embase 4, ou pouvant se situer sur un ou plusieurs côtés de la chaussure 3, et comprenant un moyen de rappel de l'élément d'appui dorsal 5.In particular, one can imagine removing the straps 8, 9, 10 and replacing them with any automatic fitting system that can be inserted between the shoe 3 and the base 4, or that can be located on one or more sides of the shoe 3, and comprising a means for returning the back support element 5.

On peut aussi prévoir une pièce intermédiaire entre la chaussure 3 et l'embase 4, la chaussure 3 étant maintenue sur la pièce intermédiaire par les sangles 8, 9, 10, et la pièce intermédiaire étant maintenue sur l'embase 4 par un moyen de retenue à encliquetage automatique. De cette façon, l'utilisateur peut au choix détacher les sangles 8, 9, 10 ou le moyen de retenue à encliquetage automatique, en fonction des conditions de pratique et d'utilisation de la planche de glisse 1.One can also provide an intermediate piece between the shoe 3 and the base 4, the shoe 3 being held on the intermediate piece by the straps 8, 9, 10, and the intermediate piece being held on the base 4 by a means of automatic snap retainer. In this way, the user can optionally detach the straps 8, 9, 10 or the self-locking retaining means, depending on the conditions of practice and use of the gliding board 1.

On peut prévoir encore d'utiliser plusieurs ressorts, par exemple deux, disposés de part et d'autre de l'élément d'appui dorsal 5.It is also possible to plan to use several springs, for example two, arranged on either side of the back support element 5.
