Definitions
- the present invention relates to a device for fixing a shoe to an article of sport such as a ski or a snowshoe, of the type comprising a coupling element for connection to the shoe, intended to be attached to the sports article which can be associated to an attachment element secured to the shoe in an area between the toes toes and the "metatarsophalangeal" joint, and which has such flexibility that one can freely lift the heel of the shoe in relation to the sports article once the coupling achieved.
- a fastening is generally provided on the upper face ski allowing the pivoting of the boot around an axis of articulation, so that the heel of said shoe can be lifted freely relative to the ski.
- the axis of articulation of the shoe is normally located at the front end of the shoe, which causes an unnatural course when the heel is lifted from the ski, because the part of the course of a foot is found between the tips of the toes and the so-called metatarsophalangeal joint. This results in excessive energy expenditure and premature fatigue of the skier. These adverse effects are particularly troublesome when practicing the so-called style classic where the skier unrolls his foot before the impulse.
- WO 84/03225 proposes a combination of a fixing and a shoe adapted to the latter in which the coupling element for the connection to the shoe is located in the area thereof corresponding to the prominence of the big toe.
- this known attachment has drawbacks in that the part of the boot located in front of the connection area loses contact with the ski each time the skier strides. It is therefore only the coupling element to the shoe which must take up all the efforts, either transverse or longitudinal, when the rear part of the shoe is raised. This results in material fatigue in the area connection, either on the fixing side or on the sole side.
- control and guidance of the ski during the lifting of the heel of the shoe is therefore not optimal.
- the present invention therefore aims to provide a fixing device improved which improves the control of the sports article by the foot, while allowing the natural unwinding of the user's foot.
- the central idea of the invention is to improve the control of the sports article by the foot of the skier in a binding of the type known by WO 84/03225, creating more cooperation effective between the sole of the shoe and the binding and the sports article, in the area of the shoe corresponding to the area of the foot between the tips of the toes and the area of connection.
- the fixing device is provided with means of control allowing permanent contact, direct or indirect, of the part of the sole of the shoe located in front of the connection area with the sports article when you lift the heel of the shoe.
- the control means may include a stop limiting the maximum vertical bending of the coupling element with respect to the ski. This stop therefore limits the maximum angle formed by the sole of the boot and the upper surface of the ski.
- the control means may include a transverse guide of the coupling element so to provide cross directional control of the coupling element.
- the control means can also be formed by determining the bending curve of the coupling element, said bending curve ensuring permanent contact with the part of the sole of the shoe located in front of the point of embedding with the ski when the heel is released from the shoe.
- FIGs 1 and 2 is shown the front of a shoe 1 which is connected to a sports article such a cross-country or touring ski 2 by means of a fixing device 3 according to the present invention.
- the fixing device 3 comprises a control member 4 for opening-closing of known type, which in the example described is based on the principle of a kneepad.
- a control device is already described in patent FR 2,638,974 in the name of the applicant.
- a rotation of an operating lever 5 of the control member 4 causes the translation, inside a hollow front part 25 of a guide edge 25, 26, of a coupling element which in the example described consists of a wire 6 bent metal.
- the guide edge 25, 26 cooperates in a manner known per se with an associated groove 8a formed in the sole 8 of the shoe.
- the coupling element 6 can be constituted by any other elastic means such as for example by a leaf spring having a certain flexibility with respect to bending in a longitudinal and vertical plane with respect to the upper face 10 of the ski.
- This wire 6 is folded in the shape of a "U” and fixed on the control member 4, on the front side of the ski, by its free ends 19. It extends essentially parallel to ski 2 and ends in a section angled forming a hook 7.
- the length of the coupling element 6 is chosen such that the hook 7 is located below an area of the sole 8 of the shoe 1 corresponding to a foot area between the tips of the toes and the so-called metatarsophalangeal part. So the bending of the element 6 coupling corresponds to the natural course of a foot.
- the outer sole 8 of the shoe is provided with a corresponding attachment means 9 adapted to cooperation with the coupling element.
- This attachment means 9 can be constituted by an axis of circular section, a rectangular section beam, a notch, ... etc.
- the attachment means is constituted by a metal pin 9 having a circular section.
- the boot 1 is placed on the upper face 10 of the ski so that the fastening axis 9 integral with the outer sole of the shoe 1 is inserted into a transverse groove 11 of the guide edge 25, 26 of the binding 3.
- the bent wire 6 orthogonally crosses the bottom 13 of this groove 11.
- the operating lever 5 is actuated to thus causing a translation of the bent wire 6 and the hook 7 towards the front of the ski, that is to say to the left in the drawing, thus leaving the hook 7 from the housing 12.
- the hook 7 is located in the groove 11.
- the axis 9 of the sole 8 of the shoe 1 is then completely locked between the hook 7 and a wall 15 limiting the transverse groove 11 towards the front of the ski.
- the shoe 1 is then fixed to the ski 1 by means of the fixing device in this closed position of the control unit 4.
- the axis 9 slides upwards from the wall (ramp) 15 of the groove 11, said wall 15 having a shape corresponding essentially to a circular arc centered on the front 25a of the guide edge 25 corresponding to an area "embedding" of the bent wire 6.
- the bent wire 6 is bent upwards at the interior of a housing 14 formed in the part of the guide edge 25 extending from the groove 11 towards the front of the ski 1.
- This housing 14 has an upper wall 14a in the form of a ramp going in increasing from the front end 25a of the guide ramp to the level of the groove 11, to allow bending and optionally guiding the bent wire 6 during the lifting of the heel.
- the upper wall 17 of the guide edge 25 closes the housing 14 upwards.
- the rear end of the upper wall 17 therefore constitutes a stop 18 limiting the maximum upward bending of the wire 6, as shown in figure 3.
- the maximum lifting of the heel of the shoe 1 and therefore the maximum angle between the sole of shoe 1 and the upper surface of the ski are thus limited by the stopper 18, this which allows improved control, throughout the lifting phase.
- the abutment of the wire 6 against the stop 18 allows the recovery of forces, and thus relieves the fixing 19 of the wire 6 on the front side of the ski.
- the bent wire 6 in the example described is formed by two longitudinal and essentially parallel branches 20, 21, which are connected one with the other by a bent cross-member forming the hook 7 in cross section ( Figures 1 to 3).
- each longitudinal branch 20, 21, is housed inside a separate housing 14 respectively 14 '.
- the walls 22, 23, delimiting the housings 14, 14 ', inwards are inclined, upwards, outwards, so that the branches longitudinal 20, 21, connected to each other by the crosspiece 7 are also bent towards the outside of the ski in a plane essentially parallel to the ski surface during bending from wire 6 upwards.
- the branches 20, 21 permanently tend to join their initial position at the bottom of the housings 14, 14 ', and therefore a restoring force which tends to return the ski 1 or other sporting item pressed against the heel.
- the bending energy of the wire 6 is restored at the end of the pulse.
- the embedded wire 6 then serves both to conserve the energy of reminder of the ski and to lock the axis 9 integral with the boot 1.
- the vertical walls of the housings 14, 14 ', further form a transverse guide of the coupling element 6, this which allows an improved control of the ski or the sporting article during all the phase of heel lift.
- transverse guide of the coupling element 6 can be constituted by any other means having transverse guiding properties, such as for example grooves, spikes, ... etc.
- the bending curve of the wire 6 is determined by factors, such as the shape of the housings 14, 14 ′, particularly the shape and the orientation of their internal walls 22, 23, the characteristics of the material of the wire 6, and the how it is fixed and guided in 19, 25.
- the bending of the wire 6 is defined by said parameters so that the part 24 of the sole 8 of the shoe 1 located in front of the attachment means (axis) 9 remains constantly in direct or indirect contact with the ski when the heel is released from the boot 1.
- This effect can be obtained by rounding 24a of said part 24 of shoe 1, which is adapted to the bending curve of the coupling element 6.
- the sole 8 has a longitudinal groove cooperating with the guide edge 25, 26. During the unwinding of part 24 of the shoe, not only the axis 9 but also the guide edge 25, 26, take up transverse forces.

Abstract
Description
La présente invention concerne un dispositif de fixation d'une chaussure à un article de sport tel qu'un ski ou une raquette à neige, du type comportant un élément d'accouplement pour le raccordement à la chaussure, destiné à être fixé à l'article de sport qui peut être associé à un élément d'attache solidaire de la chaussure dans une zone comprise entre le bout des orteils et l'articulation "métatarso-phalangienne", et qui a une flexibilité telle qu'on peut librement soulever le talon de la chaussure par rapport à l'article de sport une fois l'accouplement réalisé.The present invention relates to a device for fixing a shoe to an article of sport such as a ski or a snowshoe, of the type comprising a coupling element for connection to the shoe, intended to be attached to the sports article which can be associated to an attachment element secured to the shoe in an area between the toes toes and the "metatarsophalangeal" joint, and which has such flexibility that one can freely lift the heel of the shoe in relation to the sports article once the coupling achieved.
Pour la pratique du ski de fond, on prévoit généralement une fixation sur la face supérieure de ski permettant le pivotement de la chaussure autour un axe d'articulation, de façon que le talon de ladite chaussure puisse être soulevé librement par rapport au ski. L'axe d'articulation de la chaussure est normalement situé au niveau de l'extrémité avant de la chaussure, ce qui provoque un déroulé peu naturel lorsque le talon est soulevé du ski, car la partie de déroulé naturelle d'un pied se trouve entre le bout des orteils et l'articulation dite métatarso-phalangienne. Il en résulte une dépense excessive d'énergie et une fatigue prématurée du skieur. Ces effets défavorables sont particulièrement gênants lorsqu'on pratique le style dit classique où le skieur déroule son pied avant l'impulsion.For the practice of cross-country skiing, a fastening is generally provided on the upper face ski allowing the pivoting of the boot around an axis of articulation, so that the heel of said shoe can be lifted freely relative to the ski. The axis of articulation of the shoe is normally located at the front end of the shoe, which causes an unnatural course when the heel is lifted from the ski, because the part of the course of a foot is found between the tips of the toes and the so-called metatarsophalangeal joint. This results in excessive energy expenditure and premature fatigue of the skier. These adverse effects are particularly troublesome when practicing the so-called style classic where the skier unrolls his foot before the impulse.
Par ailleurs, pour la technique du ski de fond dite du skating, on recherche à reculer l'axe d'articulation de la chaussure pour un meilleur contrôle du ski. La même remarque est valable pour la pratique de la raquette à neige.In addition, for the technique of cross-country skiing known as skating, we seek to reverse the axis articulation of the boot for better control of the ski. The same remark is valid for snowshoeing.
Pour remédier à ces problèmes, le WO 84/03225 propose une combinaison d'une fixation de fond et d'une chaussure adaptée à cette dernière dans laquelle l'élément d'accouplement pour le raccordement à la chaussure est situé dans la zone de celle-ci correspondant à l'éminence du gros orteil. Cependant, cette fixation connue présente des inconvénients en ce que la partie de la chaussure située devant la zone de raccordement perd le contact avec le ski chaque fois que le skieur pratique une foulée. C'est donc seulement l'élément d'accouplement à la chaussure qui doit reprendre tous les efforts, soit transversaux, soit longitudinaux, lorsque la partie arrière de la chaussure est soulevée. Il en résulte une fatigue du matériau dans la zone de raccordement, soit coté fixation, soit coté semelle.To remedy these problems, WO 84/03225 proposes a combination of a fixing and a shoe adapted to the latter in which the coupling element for the connection to the shoe is located in the area thereof corresponding to the prominence of the big toe. However, this known attachment has drawbacks in that the part of the boot located in front of the connection area loses contact with the ski each time the skier strides. It is therefore only the coupling element to the shoe which must take up all the efforts, either transverse or longitudinal, when the rear part of the shoe is raised. This results in material fatigue in the area connection, either on the fixing side or on the sole side.
Par ailleurs, le contrôle et le guidage du ski pendant le soulèvement du talon de la chaussure n'est de ce fait pas optimal.Furthermore, the control and guidance of the ski during the lifting of the heel of the shoe is therefore not optimal.
La présente invention a donc comme objectif de fournir un dispositif de fixation perfectionné qui améliore le contrôle de l'article de sport par le pied, tout en permettant le déroulé naturel du pied de l'utilisateur.The present invention therefore aims to provide a fixing device improved which improves the control of the sports article by the foot, while allowing the natural unwinding of the user's foot.
L'idée centrale de l'invention est d'améliorer le contrôle de l'article de sport par le pied du skieur dans une fixation de type connue par le WO 84/03225, en créant une coopération plus efficace entre la semelle de la chaussure et la fixation et l'article de sport, dans la zone de la chaussure correspondant à la zone du pied comprise entre le bout des orteils et la zone de raccordement. A cet effet, selon la présente invention, le dispositif de fixation est pourvu de moyens de contrôle permettant un contact permanent, direct ou indirect, de la partie de la semelle de la chaussure située en avant de la zone de raccordement avec l'article de sport lorsqu'on soulève le talon de la chaussure. The central idea of the invention is to improve the control of the sports article by the foot of the skier in a binding of the type known by WO 84/03225, creating more cooperation effective between the sole of the shoe and the binding and the sports article, in the area of the shoe corresponding to the area of the foot between the tips of the toes and the area of connection. To this end, according to the present invention, the fixing device is provided with means of control allowing permanent contact, direct or indirect, of the part of the sole of the shoe located in front of the connection area with the sports article when you lift the heel of the shoe.
Les moyens de contrôle peuvent comporter une butée limitant la flexion verticale maximale de l'élément d'accouplement par rapport au ski. Cette butée limite donc l'angle maximal formé par la semelle de la chaussure et la surface supérieure du ski.The control means may include a stop limiting the maximum vertical bending of the coupling element with respect to the ski. This stop therefore limits the maximum angle formed by the sole of the boot and the upper surface of the ski.
Les moyens de contrôle peuvent comporter un guidage transversal de l'élément d'accouplement afin de fournir un contrôle en direction transversale de l'élément d'accouplement.The control means may include a transverse guide of the coupling element so to provide cross directional control of the coupling element.
Les moyens de contrôle peuvent également être formés par la détermination de la courbe de flexion de l'élément d'accouplement, ladite courbe de flexion assurant un contact permanent de la partie de la semelle de la chaussure située devant le point d'encastrement avec le ski lorsqu'on libère le talon de la chaussure.The control means can also be formed by determining the bending curve of the coupling element, said bending curve ensuring permanent contact with the part of the sole of the shoe located in front of the point of embedding with the ski when the heel is released from the shoe.
De toute façon, l'invention sera mieux comprise et d'autres caractéristiques de celle-ci seront mises en évidence à l'aide de la description qui suit en référence au dessin schématiquement en représentant, à titre d'exemple non limitatif, plusieurs modes de réalisation et dans lequel :
- la figure 1 est une vue en coupe longitudinale et verticale d'un dispositif de fixation d'une chaussure à un ski, selon la présente invention, la chaussure reposant à plat sur le ski et avant la fermeture du dispositif de fixation,
- la figure 2 est une vue en coupe longitudinale et verticale d'un dispositif de fixation d'une chaussure à un ski, selon la présente invention, la chaussure reposant à plat sur le ski et après la fermeture du dispositif de fixation,
- la figure 3 est une vue en coupe longitudinale et verticale d'un dispositif de fixation d'une chaussure à un ski, selon la présente invention, le talon de la chaussure étant soulevé,
- la figure 4 est une vue en coupe transversale selon IV-IV de la figure 2.
- FIG. 1 is a view in longitudinal and vertical section of a device for fixing a boot to a ski, according to the present invention, the boot lying flat on the ski and before the fastening device is closed,
- FIG. 2 is a view in longitudinal and vertical section of a device for attaching a boot to a ski, according to the present invention, the boot lying flat on the ski and after the closure of the binding device,

- FIG. 4 is a cross-sectional view along IV-IV of FIG. 2.
Sur les figures 1 et 2 est représenté l'avant d'une chaussure 1 qui est reliée à un article de sport tel
qu'un ski de fond ou de randonnée 2 au moyen d'un dispositif de fixation 3 selon la présente invention.
Le dispositif de fixation 3 comporte un organe de commande 4 de l'ouverture-fermeture de type connu,
qui dans l'exemple décrit est basé sur le principe d'une genouillère. Un tel organe de commande est déjà
décrit dans le brevet FR 2 638 974 au nom de la demanderesse. Une rotation d'un levier de manoeuvre
5 de l'organe 4 de commande provoque la translation, à l'intérieur d'une partie avant creuse 25 d'une
arête de guidage 25, 26, d'un élément d'accouplement qui dans l'exemple décrit est constitué d'un fil 6
métallique coudé.In Figures 1 and 2 is shown the front of a
L'arête de guidage 25, 26, coopère de façon connue en soi avec une rainure associée 8a ménagée
dans la semelle 8 de la chaussure.The
Bien entendu, l'élément d'accouplement 6 peut être constitué par tout autre moyen élastique comme
par exemple par un ressort à lame présentant une certaine flexibilité vis à vis d'une flexion dans un
plan longitudinal et vertical par rapport à la face supérieure 10 du ski.Of course, the
Ce fil 6 est plié en forme de "U" et fixé sur l'organe de commande 4, du côté avant du ski, par ses
extrémités libres 19. Il s'étend essentiellement parallèlement au ski 2 pour se terminer en une section
coudée formant un crochet 7. La longueur de l'élément d'accouplement 6 est choisie telle que le crochet
7 se trouve au-dessous d'une zone de la semelle 8 de la chaussure 1 correspondante à une zone de pied
comprise entre le bout des orteils et la partie dite métatarso-phalangienne. Ainsi, la flexion de l'élément
d'accouplement 6 correspond au déroulé naturel d'un pied.This
La semelle externe 8 de la chaussure est pourvue d'un moyen d'attache 9 correspondant adapté à
la coopération avec l'élément d'accouplement. Ce moyen d'attache 9 peut être constitué par un axe de
section circulaire, une poutre de section rectangulaire, une encoche,...etc. Dans l'exemple décrit, le
moyen d'attache est constitué par un axe 9 métallique ayant une section circulaire.The
Pour fixer la chaussure 1 au ski 2 par l'intermédiaire du dispositif de fixation 3, on procède comme
suit.To fix the
La chaussure 1 est placée sur la face supérieure 10 du ski de manière que l'axe d'attache 9
solidaire de la semelle externe de la chaussure 1 soit inséré dans une rainure transversale 11 de
l'arête de guidage 25, 26, de la fixation 3. Le fil coudé 6 traverse orthogonalement le fond 13 de cette
rainure 11. Lorsque l'organe de commande 4 est dans sa position d'ouverture, le crochet 7 du fil coudé
6 se trouve entièrement retiré vers l'arrière du ski, c'est-à-dire à droite sur le dessin, dans un logement
12 associé situé dans la zone arrière 26 de l'arête de guidage 25, 26.The
Après l'insertion de l'axe d'attache 9 dans la rainure 11, le levier de manoeuvre 5 est actionné pour
provoquer ainsi une translation du fil coudé 6 et du crochet 7 vers l'avant du ski, c'est-à-dire à gauche
sur le dessin, sortant ainsi le crochet 7 du logement 12. A la fin du mouvement de translation, le
crochet 7 se trouve dans la rainure 11. Dans la position de fermeture de l'organe de commande 4,
montrée dans la figure 2, l'axe 9 de la semelle 8 de la chaussure 1 est alors complètement verrouillé
entre le crochet 7 et une paroi 15 limitant la rainure transversale 11 vers l'avant du ski. La chaussure
1 est alors fixée au ski 1 par l'intermédiaire du dispositif de fixation dans cette position de fermeture
de l'organe de commande 4.After the insertion of the
Au cours de la pratique du sport, notamment en ski de fond ou lors de la marche en raquettes, le
talon du pied de la jambe arrière est soulevé lorsque le sportif fait une foulée vers l'avant avec l'autre
jambe. La chaussure et la fixation de ce pied arrière se trouvent alors dans la condition représentée
dans la figure 3. En soulevant le talon de la chaussure 1, l'axe 9 et le crochet 7, qui sont reculés vers
l'arrière par rapport à l'extrémité avant de la chaussure, sont également soulevés par rapport au
fond 13 de la rainure 11.During the practice of sport, especially in cross-country skiing or when walking with snowshoes, the
heel of the rear leg foot is raised when the athlete strides forward with the other
leg. The shoe and the binding of this rear foot are then in the condition shown
in Figure 3. By lifting the heel of the
Pendant le soulèvement du talon et donc de l'axe 9 et du crochet 7, l'axe 9 glisse vers le haut de la
paroi (rampe) 15 de la rainure 11, ladite paroi 15 ayant une forme correspondant essentiellement à un
arc de cercle centré sur l'avant 25a de l'arête de guidage 25 correspondant à une zone
"d'encastrement" du fil coudé 6. A la fin du soulèvement, le fil coudé 6 se trouve fléchi vers le haut à
l'intérieur d'un logement 14 formé dans la partie de l'arête de guidage 25 s'étendant de la rainure 11
vers l'avant du ski 1. Ce logement 14 présente une paroi supérieure 14a en forme de rampe allant en
croissant depuis l'extrémité avant 25a de la rampe de guidage jusqu'au niveau de la rainure 11, pour
permettre la flexion et éventuellement le guidage du fil coudé 6 pendant le soulèvement du talon. La
paroi supérieure 17 de l'arête de guidage 25 ferme le logement 14 vers le haut. L'extrémité arrière de
la paroi supérieure 17 constitue donc une butée 18 limitant la flexion maximale vers le haut du fil 6,
comme montré sur la figure 3. During the lifting of the heel and therefore of the
Le soulèvement maximal du talon de la chaussure 1 et donc l'angle maximal entre la
semelle de la chaussure 1 et la surface supérieure du ski sont ainsi limités par la butée 18, ce
qui permet un contrôle amélioré, pendant toute la phase de soulèvement. En outre,
l'aboutement du fil 6 contre la butée 18 permet la reprise des efforts, et soulage ainsi la
fixation 19 du fil 6 côté avant du ski.The maximum lifting of the heel of the
Comme il est montré dans la figure 4, le fil coudé 6 dans l'exemple décrit est formé par
deux branches longitudinales et essentiellement parallèles 20, 21, qui sont reliées l'une avec
l'autre par une traverse coudée formant le crochet 7 en coupe transversale (figures 1 à 3). Dans
l'exemple représenté à la figure 4, chaque branche longitudinale 20, 21, est logée à l'intérieur
d'un logement distinct 14 respectivement 14'. Les parois 22, 23, délimitant les logements 14,
14', vers l'intérieur sont inclinées, vers le haut, vers l'extérieur, de façon que les branches
longitudinales 20, 21, reliées l'une avec l'autre par la traverse 7 soient fléchies également vers
l'extérieur du ski dans un plan essentiellement parallèle à la surface de ski pendant la flexion
du fil 6 vers le haut. Il en résulte que les branches 20, 21, tendent en permanence à rejoindre
leur position initiale au fond des logements 14, 14', et donc une force de rappel qui tend à
faire revenir le ski 1 ou autre article de sport plaqué contre le talon. L'énergie de flexion du fil
6 est restituée en fin d'impulsion. Le fil 6 encastré sert alors à la fois à conserver l'énergie de
rappel du ski et à verrouiller l'axe 9 solidaire de la chaussure 1. Les parois verticales des
logements 14, 14', forment de plus un guidage transversal de l'élément d'accouplement 6, ce
qui permet un contrôle amélioré du ski ou de l'article de sport pendant toute la phase de
soulèvement du talon.As shown in Figure 4, the
Par ailleurs, le guidage transversal de l'élément d'accouplement 6 peut être constitué par
tout autre moyen présentant des propriétés de guidage transversal, comme par exemple des
rainures, des pointes,...etc.Furthermore, the transverse guide of the
Comme il est illustré dans la figure 3, la courbe de flexion du fil 6 est déterminée par des
facteurs, comme par exemple la forme des logements 14, 14', particulièrement la forme et
l'orientation de leurs parois internes 22, 23, les caractéristiques du matériau du fil 6, et la
façon dont il est fixé et guidé en 19, 25.As illustrated in FIG. 3, the bending curve of the
Selon l'invention, la flexion du fil 6 est définie par lesdits paramètres de telle manière que
la partie 24 de la semelle 8 de la chaussure 1 située devant le moyen d'attache (axe) 9 reste
constamment en contact direct ou indirect avec le ski lorsqu'on libère le talon de la chaussure
1. Cet effet peut être obtenu par un arrondissement 24a de ladite partie 24 de la chaussure 1,
qui est adapté à la courbe de flexion de l'élément d'accouplement 6. Ceci permet un contrôle et
un référencement de l'article de sport et en l'occurence du ski qui sont améliorés par rapport à
l'art antérieur grâce à la coopération continue entre la partie avant de la semelle et la surface
supérieure du ski pendant toutes les phase d'une foulée typique de la technique de ski de fond,
aussi bien en classique qu'en skating.According to the invention, the bending of the
Dans l'exemple décrit, la semelle 8 comporte une rainure longitudinale coopérant avec
l'arête de guidage 25, 26. Pendant le déroulement de la partie 24 de la chaussure, non
seulement l'axe 9 mais aussi l'arête de guidage 25, 26, reprennent des efforts transversaux. In the example described, the sole 8 has a longitudinal groove cooperating with
the
On notera que l'utilisation d'un tel dispositif de fixation est particulièrement intéressant pour la pratique de sports nécessitant un déroulement du pied et une assez grande amplitude dans les gestes, et notamment pour la pratique de la technique du pas de patineur en ski de fond.It will be noted that the use of such a fixing device is particularly advantageous for the practice of sports requiring an unrolling of the foot and a fairly large range of gestures, and in particular for the practice of the skating step technique in cross-country skiing.
En effet, la fixation de la chaussure au niveau de la zone d'articulation métatarso-phalangienne apporte de nombreux avantages :
- prise d'appui directe,
- transmission directe des efforts,
- meilleurs contrôle et précision de guidage du ski,...,
- direct support,
- direct transmission of forces,
- better control and precision of ski guidance, ...,
