- the retaining stirrup and the locking member rotate as a unit during ski touring; it is then possible to make the elastically deformable element act against the locking member to oppose the pivoting of the assembly.
- the locking member is advantageously provided with a recess accessible by the tip of a ski pole in order to facilitate the release of the binding.
- the ski binding device comprises a base plate 1 fixed on a ski S by means of three screws 2. It also comprises a retaining bracket 3 which is constituted a horizontal plate 4 delimited by lateral edges 5, 6, extending vertically along the edges of the ski.
- the front edges 6 (directed to the left of the figures) are higher than the rear edges 5.
- the rear part of the edges 6 which overhangs the edges 5 is folded at right angles towards the inside of the ski to form vertical and transverse projections 7.
- the base plate 1 is provided with a pair of side cheeks 8, extending vertically, which the edges 6 of the stirrup 3 embrace in the manner of a yoke.
- a transverse rod 9 crosses the cheeks 8 and the edges 6 of the stirrup 3 to serve as a pivot axis for the latter.
- a locking member 10 in the form of a lever which is also articulated on the axis 9. It will be noted that the axis 9 is located a short distance above the ski S.
- a bowl 11 open towards the top and towards the rear of the ski while the rear part of the lever 10 carries a prominence, or spout 12.
- a torsion spring 13 one of the end branches of which bears against the plate 1 and the other against the lever 10. This spring biases the lever 10 to rotate it around the 'axis 9, clockwise. This pivoting is limited by the fact that the part 14 of the lever 10 which is located under the spout 12 abuts against the plague 4 of the stirrup 3, which is itself in abutment against the ski.
- the spring 13 is located inside a cavity 15 which is isolated from the outside environment (snow, ice, mud ...) by means of two superimposed sealing tongues 16,17 formed respectively on the base plate 1 and on the locking lever 10.
- grooves 18 are formed forming slides, arranged slightly obliquely relative to the vertical.
- An element 19 of elastically deformable material such as synthetic rubber is inserted in the slides 18 so as to occupy the space between the cheeks 8.
- the element 19 carries an elastic tab 20 which penetrates into a hole in base plate 1 to retain it.
- the underside of the rear part of the elastic element 19 is hollowed out, so that this part takes the form of a tongue 21 which extends above the ski, in the direction of the locking lever 10.
- the lateral edges 21 a of the tongue 21 are slightly longer than its central part 21 b.
- FIGS. 3 and 4 The cross-country ski boot intended to cooperate with the binding which has just been described is shown in FIGS. 3 and 4.
- This boot C has a front part 22 forming an integral part of the sole 23 and projecting slightly at the front of the vamp 24.
- the front part 22, which has a height significantly greater than that of the sole 23, is hollowed out by two lateral slots 25 constituting a hooking contour intended to cooperate with the projections 7 of the binding, as will be explained further.
- Part 22 has a front face 26 slightly sloping backwards when moving from top to bottom. On the top of the part 22 is hollowed out a central notch 27.
- the assembly works as follows.
- the skier To put his shoe in place in the binding, the skier has the front part 22 of his shoe above the stirrup 3 so that the slots 25 are opposite the projections 7 of the stirrup. He presses the tip of the foot down, the slots 25 engaging on the projections 7 while the inclined front face 26, which acts like a ramp, pushes the locking lever 10 forward, against the spring 13.
- the underside 28 of the front part of the sole which is slightly recessed to compensate for the thickness of the plate 4 of the stirrup 3 comes into contact with the latter, the locking spout 12 automatically snaps into the notch 27, under the thrust of the spring 13.
- the lifting of the heel of the skier causes the pivoting of the retaining stirrup 3 and of the locking member 10 around the axis 9, in the opposite direction to that of Clockwise.
- the spring 13 is first stressed.
- the front wall of the lever 10 meets the edges 21a of the tongue 21, causing their relatively easy deformation, then the tongue 21 itself, causing its progressive bending.
- the elastic resistance opposing the lifting of the heel is therefore increasingly strong; the amplitude of lifting of the heel is limited to an angle of approximately 90 degrees, angle for which the tongue 21 is bent and compressed to the maximum.
- the tongue 21 relaxes, helping the heel of the boot to descend onto the ski.
- the front part of the sole has vertical sides 29 which, in the road position, are embedded between the edges 5 of the stirrup 3. Thanks to this arrangement, the shoe is perfectly maintained in the lateral direction in the stirrup 3 and ski guidance is excellent.
- This background set is both simple and efficient.
- the position of the pivot axis 9, just at the tip of the boot and very low on the ski is ideal.
- the front overhang of the front part 22 is of short length and does not in any way hamper the skier in his activities other than skiing.
- the elastic element 19 being removable, by unclipping it in the base plate 1, it is possible to replace it with another element of different hardness in order to adapt it to the style of the skier and / or to the course layout.
- Figures 8 to 10 show another embodiment of the present fixing device.
- an elastic member 19a which alone assumes the functions previously assigned to the elastic element 19 and the spring 13, and which, when walking, works on compression and not on bending.
- the single elastic member 19a provided in this embodiment consists of a pad made of elastic material, for example cellular polyurethane.
- This buffer is disposed above the base plate 1a of the corresponding device and its front end 30 is engaged inside a retaining end piece 3, integral with this base plate.
- This elastic member tends to push the locking lever 10a into the shoe retaining position C, which makes the presence of an additional spring, such as the spring 13 provided in the previous embodiment, superfluous.
- this elastic member also has the function of ensuring the role assigned to the elastic element 19 existing in this previous embodiment.
- the lifting of the heel of the boot causes the retaining stirrup 3a and the locking member 10a to pivot about the axis 9a, counterclockwise. .
- the stirrup 3a and the locking member 10a thus press on the elastic pad 19a which is compressed.
- the elastic resistance opposing the lifting of the heel is therefore increasingly strong.
- the elastic buffer 19a relaxes, helping the heel of the boot to descend onto the ski.
- the release of the binding is achieved by pushing the lever 10a forward, either by hand or by pressing the tip of a stick in the bowl 11a of this lever. This maneuver is obviously carried out against the pressure exerted by the single elastic member 19a provided in this embodiment.
- the corresponding fixing device therefore has the same operating characteristics and advantages as that shown in FIGS. 1 to 7.

Abstract
Description
La présente invention a pour objet un ensemble pour ski de fond qui comprend une chaussure et un dispositif de fixation de la partie avant de celle-ci sur un ski.The present invention relates to a set for cross-country skiing which comprises a boot and a device for fixing the front part thereof on a ski.
On connaît par le brevet US-A- 4.191.396, un ensemble pour ski de fond dans lequel la partie avant de la semelle présente un prolongement important venant se loger dans un boîtier de forme complémentaire articulé sur le ski autour d'un axe transversal disposé à l'avant de la pointe de la chaussure. Dans ce mode de réalisation connu, on prévoit également un organe de verrouillage élastique coopérant avec la partie antérieure de la chaussure de manière à autoriser sa mise en place automatique par emboîtement dans l'étrier de retenue et à interdire le retrait de celle-ci sous les sollicitations auxquelles est soumise la chaussure durant l'utilisation du ski. L'articulation ainsi réalisée permet un soulèvement correct du talon durant la marche à skis. Toutefois la position de l'axe d'articulation, en avant du prolongement de semelle et, par conséquent bien en avant de la pointe du pied ne permet pas une marche naturelle et efficace du skieur. En effet, des essais pratiques montrent que l'emplacement idéal de l'axe de pivotement de la chaussure sur le ski de fond se trouve juste à la pointe du pied. Par ailleurs, la mise en place de la chaussure dans la fixation est réalisée d'arrière en avant, ce qui est peu commode car le ski risque d'avancer durant cette opération. Enfin, il convient de noter que la présence d'un prolongement de semelle est inesthétique et constitue une gêne pour le skieur lorsqu'il n'est pas sur ses skis, notamment pour la marche et la conduite automobile.US Pat. No. 4,191,396 discloses an assembly for cross-country skiing in which the front part of the sole has a significant extension which is received in a housing of complementary shape articulated on the ski around a transverse axis. disposed at the front of the toe of the shoe. In this known embodiment, there is also provided an elastic locking member cooperating with the front part of the shoe so as to allow it to be automatically put into place by fitting into the retaining stirrup and to prohibit its removal under the stresses to which the boot is subjected during the use of the ski. The joint thus produced allows correct heel lifting during ski walking. However, the position of the articulation axis, in front of the sole extension and therefore well in front of the toe does not allow natural and efficient walking by the skier. Indeed, practical tests show that the ideal location of the pivot axis of the boot on the cross-country ski is just at the tip of the foot. Furthermore, the installation of the boot in the binding is carried out from back to front, which is inconvenient since the ski risks advancing during this operation. Finally, it should be noted that the presence of a sole extension is unsightly and constitutes a discomfort for the skier when he is not on his skis, in particular for walking and driving.
On connaît également par le brevet allemand DE-A-3.023.774, un dispositif de fixation pour ski de fond dans lequel l'extrémité avant de la chaussure est maintenue dans un étrier qui lui-même est monté pivotant sur le ski autour d'un axe transversal qui est lui-même disposé juste à l'avant de la pointe de la chaussure, ce qui permet dans une certaine mesure d'éliminer les inconvénients dûs à la fixation réalisée conformément au brevet américain vu précédemment. Toutefois dans les réalisations illustrées par ce brevet allemand, la mise en place de la chaussure dans son étrier s'effectue à nouveau selon un mouvement sensiblement parallèle au plan du ski et non pas par un mouvement de bas en haut plus naturel pour le skieur chaussant cette fixation, un tel mouvement de bas en haut s'accompagnant en outre de la mise en place automatique d'un levier de verrouillage immobilisant l'avant de la chaussure dans son étrier.Also known from German patent DE-A-3,023,774, a fastening device for cross-country skiing in which the front end of the boot is held in a stirrup which itself is pivotally mounted on the ski around a transverse axis which is itself arranged just in front of the toe of the shoe, which makes it possible to a certain extent to eliminate the drawbacks due to the fixing carried out in accordance with the American patent seen previously. However in the embodiments illustrated by this German patent, the fitting of the boot in its stirrup is again carried out in a movement substantially parallel to the plane of the ski and not by a more natural movement from bottom to top for the skier wearing this binding, such a movement from bottom to top, which is also accompanied by the automatic installation of a locking lever immobilizing the front of the shoe in its stirrup.
La présente invention se propose de réaliser un ensemble pour ski de fond dans lequel la mise en place de la chaussure dans la fixation est réalisée par emboîtement de haut en bas, cette mise en place se faisant tout-à-fait automatiquement, c'est-à-dire sans intervention manuelle du skieur, tandis qu'une fois la chaussure en place dans la fixation, celle-ci peut pivoter sur le ski en une zone voisine du bout du pied, avec une amplitude élevée.The present invention proposes to produce an assembly for cross-country skiing in which the fitting of the boot into the binding is carried out by fitting from top to bottom, this fitting being done completely automatically, that is that is to say without manual intervention of the skier, while once the boot in place in the binding, the latter can pivot on the ski in a region close to the end of the foot, with a high amplitude.
A cet effet l'ensemble pour ski de fond objet de la présente invention, comprenant une chaussure et un dispositif de fixation de celle-ci sur un ski, dans lequel la partie antérieure de la chaussure présent en vue de dessus un contour d'accrochage tandis que le dispositif de fixation comporte un étrier de retenue pourvu de moyens d'accrochage de forme complémentaire, l'étrier étant articulé sur le ski autour d'un axe transversal disposé juste à l'avant de la pointe de la chaussure, un organe de verrouillage sollicité par un organe élastique étant agencé pour coopérer avec la partie antérieure de la chaussure de manière à autoriser sa mise en place automatique par emboîtement dans l'étrier de retenue et à en interdire le retrait sous les sollicitations auxquelles est soumise la chaussure durant l'utilisation du ski, se caractérise en ce que la partie antérieure de la chaussure présente une face frontale inclinée vers l'avant de bas en haut, apte à repousser vers l'avant du ski l'organe de verrouillage au cours de la mise en place de la chaussure et une encoche supérieure apte à recevoir par encliquetage un bec de l'organe de verrouillage après mise en place de l'avant de la chaussure dans l'étrier de retenue, par engagement de haut en bas d'une paire de fentes latérales sensiblement verticales ménagées dans le contour d'accrochage de la partie antérieure de la chaussure sur des saillies transversales tournées vers l'intérieur du ski et portées par l'étrier de retenue, l'organe de verrouillage étant constitué par un levier qui pivote autour du même axe transversal que l'étrier.To this end, the cross-country ski assembly which is the subject of the present invention, comprising a boot and a device for fixing the latter to a ski, in which the front part of the boot, present in top view, a hooking contour. while the fastening device comprises a retaining stirrup provided with hooking means of complementary shape, the stirrup being articulated on the ski around a transverse axis disposed just in front of the toe of the boot, a member locking mechanism urged by an elastic member being arranged to cooperate with the front part of the shoe so as to allow it to be automatically put into place by fitting into the retaining clip and to prohibit its removal under the stresses to which the shoe is subjected during the use of the ski, is characterized in that the front part of the boot has a front face inclined forwards from bottom to top, capable of pushing the member towards the front of the ski of locking during the fitting of the boot and an upper notch capable of receiving by snap-fitting a beak of the locking member after fitting of the front of the boot in the retaining clip, by engagement of top to bottom of a pair of substantially vertical lateral slots formed in the hooking contour of the front part of the boot on transverse projections turned towards the inside of the ski and carried by the retaining stirrup, the lock being constituted by a lever which pivots about the same transverse axis as the stirrup.
Le dispositif de fixation comporte de préférence un élément élastiquement déformable, agencé pour opposer une résistance progressivement croissante au mouvement de pivotement de l'étrier de retenue. Cet élément est de préférence amovible.The fixing device preferably comprises an elastically deformable element, arranged to oppose a progressively increasing resistance to the pivoting movement of the retaining stirrup. This element is preferably removable.
Avantageusement l'étrier de retenue et l'organe de verrouillage tournent en bloc durant la marche à skis; il est alors possible de faire agir l'élément déformable élastiquement contre l'organe de verrouillage pour s'opposer au pivotement de l'ensemble.Advantageously, the retaining stirrup and the locking member rotate as a unit during ski touring; it is then possible to make the elastically deformable element act against the locking member to oppose the pivoting of the assembly.
L'organe de verrouillage est avantageusement pourvu d'un évidement accessible par la pointe d'un bàton de ski en vue de faciliter le déchaussage de la fixation.The locking member is advantageously provided with a recess accessible by the tip of a ski pole in order to facilitate the release of the binding.
Pour bien immobiliser la chaussure en direction latérale dans l'étrier de retenue, il est possible de prévoir sur celui-ci une paire de nervures longitudinales adaptées pour coopérer avec des flancs latéraux formés dans la semelle de la chaussure.To properly immobilize the shoe in the lateral direction in the retaining stirrup, it is possible to provide thereon a pair of longitudinal ribs adapted to cooperate with lateral sides formed in the sole of the shoe.
D'autres particularités et avantages de l'invention apparaîtront au cours de la description qui va maintenant être faite en se référant aux dessins annexés qui représentent, à titre d'exemple, un mode de réalisation préférentiel d'un ensemble pour ski de fond selon l'invention.

Le dispositif de fixation de ski, appelé plus simplement "fixation", représenté aux figures 1 et 2, comprend une plaque de base 1 fixée sur un ski S au moyen de trois vis 2. Il comprend aussi un étrier de retenue 3 qui est constitué d'une plaque horizontale 4 délimitée par des rebords latéraux 5, 6, s'étendant verticalement le long des chants du ski. Les rebords avant 6 (dirigés vers la gauche des figures) sont plus hauts que les rebords arrière 5. La partie arrière des rebords 6 qui surplombe les rebords 5 est repliée à angle droit vers l'intérieur du ski pour former des saillies verticales et transversales 7.The ski binding device, more simply called "binding", represented in FIGS. 1 and 2, comprises a
La plaque de base 1 est pourvue d'une paire de joues latérales 8, s'étendant verticalement, que les rebords 6 de l'étrier 3 embrassent à la manière d'une chape. Une tige transversale 9 traverse-les joues 8 et les rebords 6 de l'étrier 3 pour servir d'axe de pivotement à ce dernier. Entre les joues 8 est monté un organe de verrouillage 10 en forme de levier qui est également articulé sur l'axe 9. On notera que l'axe 9 est situé à faible distance au-dessus du ski S. Dans le dessus du levier 10 est creusée une cuvette 11 ouverte vers le haut et vers l'arrière du ski tandis que la partie arrière du levier 10 porte une proéminence, ou bec 12.The
Autour de l'axe 9 est disposé un ressort de torsion 13 dont l'une des branches d'extrémité prend appui contre la plaque 1 et l'autre contre le levier 10. Ce ressort sollicite le levier 10 pour le faire pivoter autour de l'axe 9, dans le sens des aiguilles d'une montre. Ce pivotement est limité du fait que la partie 14 du levier 10 qui est située sous le bec 12 vient en butée contre la plague 4 de l'étrier 3, laquelle est elle-même en appui contre le ski. Le ressort 13 est situé à l'intérieur d'une cavité 15 qui est isolée du milieu extérieur (neige, glace, boue...) au moyen de deux languettes d'étanchéité superposées 16,17 formées respectivement sur la plaque de base 1 et sur le levier de verrouillage 10. Dans les parois des joues 8, vers l'intérieur du ski, sont creusées des rainures 18 formant glissières, disposées légèrement en oblique par rapport à la verticale. Un élément 19 en matériau élastiquement déformable tel qu'un caoutchouc synthétique est enfiché dans les glissières 18 de manière à occuper l'espace compris entre les joues 8. A sa partie inférieure, l'élément 19 porte une patte élastique 20 qui pénètre dans un trou de la plaque de base 1 pour en assurer la retenue.Around the
Le dessous de la partie arrière de l'élément élastique 19 est évidé, si bien que cette partie affecte la forme d'une languette 21 qui s'étend au-dessus du ski, en direction du levier de verrouillage 10. Les bords latéraux 21 a de la languette 21 sont légèrement plus longs que sa partie centrale 21 b.The underside of the rear part of the
La chaussure de ski de fond destinée à coopérer avec la fixation qui vient d'être décrite est représentée aux figures 3 et 4. Cette chaussure C comporte une partie antérieure 22 formant partie intégrante de la semelle 23 et débordant légèrement à l'avant de l'empeigne 24. La partie antérieure 22, qui a une hauteur nettement supérieure à celle de la semelle 23, est creusée de deux fentes latérales 25 constituant un contour d'accrochage destiné à coopérer avec les saillies 7 de la fixation, comme il sera expliqué plus loin. La partie 22 présente une face frontale 26 légèrement en pente vers l'arrière lorsqu'on se dirige de haut en bas. Sur le dessus de la partie 22 est creusée une encoche centrale 27.The cross-country ski boot intended to cooperate with the binding which has just been described is shown in FIGS. 3 and 4. This boot C has a
L'ensemble fonctionne comme suit.The assembly works as follows.
Pour mettre en place sa chaussure dans la fixation, le skieur présente la partie antérieure 22 de sa chaussure au-dessus de l'étrier 3 de sorte que les fentes 25 soient en regard des saillies 7 de l'étrier. Il presse la pointe du pied vers le bas, les fentes 25 s'engageant sur les saillies 7 tandis que la face frontale inclinée 26, qui agit à la manière d'une rampe, repousse le levier de verrouillage 10 vers l'avant, à l'encontre du ressort 13. Lorsque le dessous 28 de la partie avant de la semelle, qui est légèrement renfoncée pour compenser l'épaisseur de la plaque 4 de l'étrier 3, vient en contact avec cette dernière, le bec de verrouillage 12 vient s'encliqueter automatiquement dans l'encoche 27, sous la poussée du ressort 13.To put his shoe in place in the binding, the skier has the
Cette opération est représentée aux figures 5 et 6.This operation is shown in Figures 5 and 6.
Pendant la marche à skis, représentée à la figure 7, le soulèvement du talon du skieur provoque le pivotement de l'étrier de retenue 3 et de l'organe de verrouillage 10 aurtour de l'axe 9, dans le sens contraire à celui des aiguilles d'une montre. Durant cette phase le ressort 13 est d'abord sollicité. Ensuite la paroi avant du levier 10 rencontre les bords 21 a de la languette 21, provoquant leur déformation relativement aisée, puis la languette 21 ellé-même, provoquant sa flexion progressive. La résistance élastique s'opposant au soulèvement du talon est donc de plus en plus forte; l'amplitude de soulèvement du talon est limitée à un angle d'environ 90 degrés, angle pour lequel la languette 21 est fléchie et comprimée au maximum. A la fin du pas, la languette 21 se détend, aidant lé talon de la chaussure à redescendre sur le ski.During the ski tour, represented in FIG. 7, the lifting of the heel of the skier causes the pivoting of the retaining
On remarquera que la partie avant de la semelle présente des flancs verticaux 29 qui, en position chaussée, sont encastrés entre les rebords 5 de l'étrier 3. Grâce à cette disposition la chaussure est parfaitement maintenue en direction latérale dans l'étrier 3 et le guidage du ski est excellent.It will be noted that the front part of the sole has
Pour procéder au déchaussage de la fixation il suffit de repousser le levier de déchaussage 10 vers l'avant, soit à la main, soit par pression de la pointe du bàton dans la cuvette 11, et d'extraire la partie antérieure de la chaussure de l'étrier 3 en soulevant la pointe de la chaussure, le talon étant en appui sur le ski.To remove the binding, push the
Cet ensemble de fond est à la fois simple et performant. La position de l'axe de pivotement 9, juste à la pointe de la chaussure et très bas sur le ski est idéale. Le débord avant de la partie antérieure 22 est de faible longueur et ne gêne nullement le skieur dans ses activités autres que le ski.This background set is both simple and efficient. The position of the

Dans celle-ci il est prévu un organe élastique 19a qui assume, à lui seul, les fonctions dévolues précédemment à l'élément élastique 19 et au ressort 13, et qui, à la marche travaille à la compression et non pas à la flexion.Figures 8 to 10 show another embodiment of the present fixing device. In it there is provided an
Cependant la conception générale du dispositif de fixation reste la même que précédemment, de sorte que lés différents éléments constitutifs de ce dispositif sont désignés par les mêmes chiffres de référence affectés de l'indice "a".However, the general design of the fixing device remains the same as previously, so that the various constituent elements of this device are designated by the same reference numbers assigned the index "a".
L'organe élastique unique 19a prévu dans cette forme de réalisation est constitué par un tampon en matière élastique, par exemple en polyuréthane cellulaire. Ce tampon est disposé au-dessus de la plaque de base la du dispositif correspondant et son extrémité avant 30 est engagée à l'intérieur d'un embout de retenue 3, faisant corps avec cette plaque de base. Cet organe élastique tend à repousser le levier de verrouillage 10a en position de retenue de la chaussure C, ce qui rend superflue la présence d'un ressort additionnel, tel que le ressort 13 prévu dans la précédente forme de réalisation.The single
Cependant cet organe élastique a également pour fonction d'assurer le rôle dévolu à l'élément élastique 19 existant dans cétte précédente forme de réalisation. Durant la marche à skis, le soulèvement du talon de la chaussure provoque le pivotement de l'étrier de retenue 3a et de l'organe de verrouillage 10a autour de l'axe 9a, dans le sens contraire à celui des aiguilles d'une montre. L'étrier 3a et l'organe de verrouillage 10a font ainsi pression sur le tampon élastique 19a qui se trouve comprimé. La résistance élastique s'opposant au soulèvement du talon est donc de plus en plus forte. A la fin du pas, le tampon élastique 19a se détend, aidant le talon de la chaussure à redescendre sur le ski.However, this elastic member also has the function of ensuring the role assigned to the
Comme dans la forme de réalisation précédente, le déchaussage de la fixation est réalisé en repoussant le levier 10a vers l'avant, soit à la main, soit par pression de la pointe d'un bâton dans la cuvette 11a de ce levier. Cette manoeuvre est évidemment effectuée à l'encontre de la pression exercée par l'organe élastique unique 19a prévu dans cette forme de réalisation.As in the previous embodiment, the release of the binding is achieved by pushing the
Le dispositif de fixation correspondant présente donc les mêmes caractéristiques et avantages de fonctionnement que celui représenté aux figures 1 à 7.The corresponding fixing device therefore has the same operating characteristics and advantages as that shown in FIGS. 1 to 7.
