Definitions
- the present invention relates to a ski boot consisting of a lower part surrounding the foot and the heel and a collar-shaped rod hinged on the lower part and provided with at least one loop of closure and tightening, and comprising, at the rear, a rod locking device in position forward inclined descent, and means for unlocking.
- such a shoe is known from document EP-A-0 086 908.
- This shoe includes, at the rear, a rocker articulated on the rod and cooperating with a fixed stop on the shell of the shoe. Unlocking is carried out by a pressure on the upper arm of the accessible scale through a cutout in the stem.
- a seesaw can itself be equipped with an auxiliary device locking mechanism to keep the rocker in position moved away from the stop.
- Such a device is described in document CH-A-678 685.
- Direct operated scale requires cutting in the back of the rod, not very aesthetic cut and letting snow penetrate with the risk of formation of ice.
- the rocker activated by means of a cam constitutes a relatively voluminous whole.
- the control of such a scale by a cable connected to a loop of the necklace is not more convenient, as shown in US-A-5,136,794.
- the object of the present invention is to provide a less bulky locking device, do not requiring no cutting at the back of the rod, and much easier to operate with a cable traction connected to a loop of the collar or to any other control unit.
- the shoe according to the invention is characterized in that that the locking device is made up of part, of a ratchet mounted on the lower part of the shoe around a horizontal axis, having a arm directed approximately vertically towards the high and stressed by an elastic means tending to move said arm away from the hull and, on the other hand, stop located on the internal face of the rod and against which the end of the pawl arm abuts in bending over, in the locked position, and in that the unlocking means consist of a finger oriented so as to move the pawl away from the stop when activated.
- the finger advantageously constitutes the first arm of a bent lever articulated on the internal face of the rod and actuated by an actuator mounted on the face external of the stem.
- Such leverage has the advantage to be easily actuated by a cable traction connected, for example, to a loop of the collar.
- the arms of this cranked lever can be relatively short.
- the bent lever advantageously constitutes a single piece with the stopper then made in the form of a tilting stop.
- the shoe shown in Figure 1 consists essentially of a lower part formed of a variable volume shell 1 surrounding the foot and heel and a rod formed by a collar 2 articulated on the shell 1 at two opposite points 3 approximately at level of the malleolus.
- Hull 1 has two tightening loops 4 and 5.
- the collar 2 is also fitted with two closing and tightening loops 6 and 7.
- the collar 2 carries, on its internal face, a stop 8 pivotally mounted around an axis horizontal 9.
- This stop 8 is in the form of a bent lever of which a first arm 8a is maintained resting against the wall of the collar 2 by a spring in hunting horn surrounding the axis 9 and a second arm 8b, directed towards the front of the shoe and to which is attached the end of a tube 10 in which is housed a slider 30 fixed to the end of a cable 11 of which the other end is connected to the loop 6 of the collar in such a way that the opening of the loop 6 exercises a pull on the cable 11.
- a spring 31 working in compression between the slide 30 and the bottom of the tube 10.
- This spring has the function of absorbing the difference of stroke between the cable 11 and the arm 8b of the stop 8.
- the axis is shown schematically hinge 14 of the tensioning lever 15 of the loop 6 on the collar 2 and the hinge pin 16 of the tie rod 17 of this loop on the tension lever 15.
- the cable 11 is here attached to the axis 16, as shown schematically.
- a loop of the same type equips MID MATIC models by ROSSIGNOL. Although the cable has been shown connected to the upper loop 6 it is advantageous to connect it to the lower loop 7, because the opening of the loop 7 has the effect of releasing the instep and thus facilitate walking.
- the stop 8 has a substantially 8c lower face horizontal in the locked position and constituting the abutment face proper. This face 8c, which connects the two arms 8a and 8b, is limited, on the arm 8a, by a lug 8d.
- On the shell is mounted a pawl 12 articulated around a horizontal axis 13 and held in substantially vertical position by a horn spring flush mounted around axis 13.
- Figure 1 shows the shoe in the closed position tight ready for descent.
- the collar 2 is locked in the lowering position by the ratchet 12 whose arm abuts approximately perpendicularly against the underside 8c of the stop 8.
- the pawl 12 is here also in stop lateral against the lug 8d of the stop.
- Spring 31 is slightly compressed, the force it exerts being in any case less than the sum of the force of the return spring in hunting horn of the stop 8 and the force of the pawl return spring 12.
- the opening of the loop 6 has the effect of exerting a traction on the cable 11 which compresses the spring 31 by the slider 30.
- the tube 10 is in turn trained and pulls on the arm 8b of the stop 8, which has the effect of tilting this stop.
- the lug 8d spreads and rotates the pawl 12, as shown in the figure 2. In this position, the pawl is in support lateral on the end of the lug 8d. Loop 6 and thus the cable 11 can continue its race until total compression of the spring 31.
- Figure 6 shows the locking device just before the automatic re-locking of the collar 2 on the hull 1.
- the loop 6 is closed and the traction of the cable 11 on the spring 31 is released.
- Necklace 2 is still in the upright position.
- the collar 2 rocks in the direction of the arrow and when the axis 9 of the stop 8 exceeds the end of the pawl 12, the stop 8 resumes the position shown in Figure 1 under the effect of its return spring and pawl 12 comes again bend against the face 8c of the stop 8 in locking the collar 2.
- the cable 11 could be actuated by a particular organ such as an auxiliary loop, a rotary button or a pull button mounted on the collar 2.
- bent lever made up of arms 8a and 8b could be a separate part of the stop which would then a fixed part.
- the tilting stop 8 could be actuated directly, i.e. without going through a cable.
- the arm 8b could be removed and the stop, integral with its axis 9, could be actuated by its axis by means of an external organ such as a lever or button placed on the collar at the height of the stop.
- the stop could be dissociated from the unlocking member which would simply consisting of an unlocking finger corresponding to arm 8a. That’s why, in a way general, we can speak of an unlocking finger.
- Hunting horn springs could be replaced by any other elastic element tending to maintain the tilting stop, respectively the finger unlocking, and the ratchet in the position shown in Figure 1.
- Figure 7 shows an embodiment in which the pawl 12 cooperates with a stop 18 formed on collar 2. Unlocking is ensured by a lever 19 mounted around a horizontal axis on the collar 2 and whose curved lower arm 19a constitutes the unlocking finger allowing move the pawl 12 away from the stop 18. A spring in hunting horn recalls the lever clockwise. In the on position, the pawl 12 slides on the end 18a of the stop 18.
- the finger release consists of the end 20a a pusher 20 mounted on a spring 21.
- a locking of pusher 20 by rotation in position pressed could be easily achieved.
- a pawl 12 cooperating with a stop 18 formed on the collar 2.
- the stop 18 is reinforced by a metal piece 22 fixed to the collar 2 by two rivets represented by their axes 23, on each side of a cut 24 open at the bottom.
- Unlocking is ensured by a plastic rocker 25 housed without play in a cutout 27 of the collar 2 and articulated around a horizontal axis 26 on the metal part 22, the fixing rivets of which are therefore located on each side of the cutout 27.
- the rocker 25 has two push-shaped ends 25a and 25b can be operated from outside the collar 2.
- the pusher lower 25a protrudes towards the inside of the collar and constitutes the unlocking finger.
- the absence of clearance between the rocker 25 and the cutout 27 ensures, on the one hand, the sealing and, on the other hand, the maintenance by friction of the rocker in the chosen position.
- Pressing the pusher 25a has the effect of spreading the pawl 12 of the metal part 22 and of the stop 18 and therefore unlock the collar 2 which can tilt as shown in Figure 10.
- Toggle 25 is narrower than the cutout 24 in the metal part 22, so that this metal part 22 does not prevent the scale from turning enough to push and hold the pawl 12 out of the trajectory of the stop 18.

Description
La présente invention a pour objet une chaussure de ski constituée d'une partie inférieure entourant le pied et le talon et d'une tige en forme de collier articulé sur la partie inférieure et munie d'au moins une boucle de fermeture et de serrage, et comportant, à l'arrière, un dispositif de verrouillage de la tige en position de descente inclinée vers l'avant, et des moyens de déverrouillage.The present invention relates to a ski boot consisting of a lower part surrounding the foot and the heel and a collar-shaped rod hinged on the lower part and provided with at least one loop of closure and tightening, and comprising, at the rear, a rod locking device in position forward inclined descent, and means for unlocking.
Dans sa version la plus simple, une telle chaussure est connue du document EP-A-0 086 908. Cette chaussure comprend, à l'arrière, une bascule articulée sur la tige et coopérant avec une butée fixe sur la coque de la chaussure. Le déverrouillage s'effectue par une pression sur le bras supérieur de la bascule accessible à travers une découpe de la tige. Une telle bascule peut être équipée elle-même d'un dispositif auxiliaire de verrouillage permettant de maintenir la bascule en position écartée de la butée. Un tel dispositif est décrit dans le document CH-A-678 685.In its simplest version, such a shoe is known from document EP-A-0 086 908. This shoe includes, at the rear, a rocker articulated on the rod and cooperating with a fixed stop on the shell of the shoe. Unlocking is carried out by a pressure on the upper arm of the accessible scale through a cutout in the stem. Such a seesaw can itself be equipped with an auxiliary device locking mechanism to keep the rocker in position moved away from the stop. Such a device is described in document CH-A-678 685.
On connait également une chaussure équipée d'une bascule selon le document EP-A-0 086 908 et d'un bouton rotatif actionnant une came agissant sur la bascule pour la maintenir en position déverrouillée.We also know a shoe equipped with a toggle according to document EP-A-0 086 908 and a button rotary actuating a cam acting on the rocker to keep it in the unlocked position.
La bascule à actionnement direct nécessite une découpe dans le dos de la tige, découpe peu esthétique et laissant pénétrer la neige avec le risque de formation de glace. La bascule actionnée au moyen d'un came constitue un ensemble relativement volumineux. En outre, la commande d'une telle bascule par un câble relié à une boucle du collier n'est pas des plus commode, comme le montre le brevet US-A-5 136 794.Direct operated scale requires cutting in the back of the rod, not very aesthetic cut and letting snow penetrate with the risk of formation of ice. The rocker activated by means of a cam constitutes a relatively voluminous whole. In in addition, the control of such a scale by a cable connected to a loop of the necklace is not more convenient, as shown in US-A-5,136,794.
La présente invention a pour but de réaliser un dispositif de verrouillage moins volumineux, ne nécessitant pas de découpe à l'arrière de la tige, et beaucoup plus facile à actionner par un câble de traction relié à une boucle du collier ou à tout autre organe de commande.The object of the present invention is to provide a less bulky locking device, do not requiring no cutting at the back of the rod, and much easier to operate with a cable traction connected to a loop of the collar or to any other control unit.
La chaussure selon l'invention est caractérisée en ce que le dispositif de verrouillage est constitué, d'une part, d'un cliquet monté sur la partie inférieure de la chaussure autour d'un axe horizontal, présentant un bras dirigé approximativement verticalement vers le haut et sollicité par un moyen élastique tendant à écarter ledit bras de la coque et, d'autre part, d'une butée située sur la face interne de la tige et contre laquelle l'extrémité du bras du cliquet vient buter en s'arqueboutant, en position verrouillée, et en ce que les moyens de déverrouillage sont constitués d'un doigt orienté de manière à écarter le cliquet de la butée lors son actionnement.The shoe according to the invention is characterized in that that the locking device is made up of part, of a ratchet mounted on the lower part of the shoe around a horizontal axis, having a arm directed approximately vertically towards the high and stressed by an elastic means tending to move said arm away from the hull and, on the other hand, stop located on the internal face of the rod and against which the end of the pawl arm abuts in bending over, in the locked position, and in that the unlocking means consist of a finger oriented so as to move the pawl away from the stop when activated.
Le doigt constitue avantageusement le premier bras d'un levier coudé articulé sur la face interne de la tige et actionné par un organe d'actionnement monté sur la face externe de la tige. Un tel levier présente l'avantage de pouvoir être actionné facilement par un câble de traction relié, par exemple, à une boucle du collier. Les bras de ce levier coudé peuvent être relativement courts. Le levier coudé constitue avantageusement une seule pièce avec la butée réalisée alors sous la forme d'une butée basculante.The finger advantageously constitutes the first arm of a bent lever articulated on the internal face of the rod and actuated by an actuator mounted on the face external of the stem. Such leverage has the advantage to be easily actuated by a cable traction connected, for example, to a loop of the collar. The arms of this cranked lever can be relatively short. The bent lever advantageously constitutes a single piece with the stopper then made in the form of a tilting stop.
Le dessin annexé représente, à titre d'exemple, quatre
formes d'éxécution de la chaussure selon l'invention.
La chaussure représentée à la figure 1 est constituée
essentiellement d'une partie inférieure formée d'une
coque 1 à volume variable entourant le pied et le talon
et d'une tige formée d'un collier 2 articulé sur la
coque 1 en deux points opposés 3 approximativement au
niveau de la malléole. La coque 1 est munie de deux
boucles de serrage 4 et 5. Le collier 2 est également
muni de deux boucles de fermeture et de serrage 6 et 7.The shoe shown in Figure 1 consists
essentially of a lower part formed of a
A l'arrière, le collier 2 porte, sur sa face interne,
une butée 8 montée basculante autour d'un axe
horizontal 9. Cette butée 8 se présente sous la forme
d'un levier coudé dont un premier bras 8a est maintenu
en appui contre la paroi du collier 2 par un ressort en
cor de chasse entourant l'axe 9 et un second bras 8b,
dirigé vers l'avant de la chaussure et auquel est
attachée l'extrémité d'un tube 10 dans lequel est logé
un coulisseau 30 fixé à l'extrémité d'un câble 11 dont
l'autre extrémité est reliée à la boucle 6 du collier
de telle manière que l'ouverture de la boucle 6 exerce
une traction sur le câble 11. Dans le tube 10 est en
outre monté un ressort 31 travaillant en compression
entre le coulisseau 30 et le fond du tube 10. Ce
ressort a pour fonction d'absorber la différence de
course entre le câble 11 et le bras 8b de la butée 8.
Sur la figure 1, on a représenté schématiquement l'axe
d'articulation 14 du levier-tendeur 15 de la boucle 6
sur le collier 2 et l'axe d'articulation 16 du tirant
17 de cette boucle sur le levier-tendeur 15. Le câble
11 est ici attaché à l'axe 16, comme représenté
schématiquement. Une boucle du même type équipe les
modèles MID MATIC de ROSSIGNOL. Bien que le câble ait
été représenté relié à la boucle supérieure 6, il est
avantageux de le relier à la boucle inférieure 7, car
l'ouverture de la boucle 7 a pour effet de libérer le
cou de pied et ainsi de faciliter la marche.At the rear, the
La butée 8 présente une face inférieure 8c sensiblement
horizontale en position verrouillée et constituant la
face de butée proprement dite. Cette face 8c, qui relie
les deux bras 8a et 8b, est limitée, sur le bras 8a,
par un ergot 8d. Sur la coque est monté un cliquet 12
articulé autour d'un axe horizontale 13 et maintenu en
position sensiblement verticale par un ressort en cor
de chasse monté autour de l'axe 13.The
La figure 1 représente la chaussure en position fermée
serrée prête pour la descente. Dans cette position, le
collier 2 est verrouillé en position de descente par le
cliquet 12 dont le bras vient buter approximativement
perpendiculairement contre la face inférieure 8c de la
butée 8. Le cliquet 12 est ici également en butée
latérale contre l'ergot 8d de la butée. Le ressort 31
est légèrement comprimé, la force qu'il exerce étant
dans tous les cas inférieure à la somme de la force du
ressort de rappel en cor de chasse de la butée 8 et de
la force du ressort de rappel du cliquet 12.Figure 1 shows the shoe in the closed position
tight ready for descent. In this position, the
L'ouverture de la boucle 6 a pour effet d'exercer une
traction sur le câble 11 qui comprime le ressort 31 par
le coulisseau 30. Lorsque la compression du ressort 31
dépasse la résistance de la butée 8, le tube 10 est
entraíné à son tour et exerce une traction sur le bras
8b de la butée 8, ce qui a pour effet de faire basculer
cette butée. Lors de ce basculement, l'ergot 8d écarte
et fait pivoter le cliquet 12, comme représenté à la
figure 2. Dans cette position, le cliquet est en appui
latéral sur l'extrémité de l'ergot 8d. La boucle 6 et
partant le câble 11 peut poursuivre sa course jusqu'à
compression totale du ressort 31.The opening of the
La boucle 6 étant maintenue en position ouverte, la
traction sur le câble 11 subsiste et la butée 8 reste
dans la position représentée à la figure 3, ce qui
permet au collier de basculer en arrière, le cliquet
venant glisser sur l'extrémité de l'ergot 8d. Il est
ainsi soit possible d'ouvrir les deux boucles du
collier et de faire basculer celui-ci en arrière dans
une position de chaussage, représentée à la figure 4,
soit d'être en position de marche telle que représentée
à la figure 5, dans laquelle le collier 2 peut
osciller, comme indiqué par la double flèche, sans
venir se verrouiller.The
La figure 6 représente le dispositif de verrouillage
juste avant le reverrouillage automatique du collier 2
sur la coque 1. La boucle 6 est fermée et la traction
du câble 11 sur le ressort 31 est relâchée. Le collier
2 est encore en position redressée. Lors de la première
flexion de la jambe, le collier 2 bascule dans le sens
de la flèche et lorsque l'axe 9 de la butée 8 dépasse
l'extrémité du cliquet 12, la butée 8 reprend la
position représentée à la figure 1 sous l'effet de son
ressort de rappel et le cliquet 12 vient à nouveau
s'arquebouter contre la face 8c de la butée 8 en
verrouillant le collier 2.Figure 6 shows the locking device
just before the automatic re-locking of the
Le dispositif décrit est susceptible de nombreuses variantes sans sortir du cadre de l'invention.The device described is susceptible of numerous variants without departing from the scope of the invention.
En particulier, le câble 11 pourrait être actionné par
un organe particulier tel qu'une boucle auxiliaire, un
bouton rotatif ou un bouton de traction monté sur le
collier 2.In particular, the
Le levier coudé constitué des bras 8a et 8b pourrait
être une pièce distincte de la butée qui serait alors
une pièce fixe.The bent lever made up of
La butée basculante 8 pourrait être actionnée
directement, c'est-à-dire sans passer par un câble.
Dans ce cas le bras 8b pourrait être supprimé et la
butée, solidaire de son axe 9, pourrait être actionnée
par son axe au moyen d'un organe extérieur tel qu'un
levier ou un bouton placé sur le collier à la hauteur
de la butée. Dans ce cas aussi, la butée pourrait être
dissociée de l'organe de déverrouillage qui serait
simplement constitué d'un doigt de déverrouillage
correspondant au bras 8a. C'est pourquoi, d'une manière
générale, on peut parler d'un doigt de déverrouillage.The tilting
Les ressorts en cor de chasse pourraient être remplacés par tout autre élément élastique tendant à maintenir la butée basculante, respectivement le doigt de déverrouillage, et le cliquet dans la position représentée à la figure 1.Hunting horn springs could be replaced by any other elastic element tending to maintain the tilting stop, respectively the finger unlocking, and the ratchet in the position shown in Figure 1.
Trois autres formes d'exécution sont illustrées aux figures 7 à 10, à titre d'exemples.Three other embodiments are illustrated in Figures 7 to 10, by way of examples.
La figure 7 représente une forme d'exécution dans
laquelle le cliquet 12 coopère avec une butée 18 formée
sur le collier 2. Le déverrouillage est assuré par un
levier 19 monté autour d'un axe horizontal sur le
collier 2 et dont le bras inférieur recourbé 19a
constitue le doigt de déverrouillage permettant
d'écarter le cliquet 12 de la butée 18. Un ressort en
cor de chasse rappelle le levier dans le sens horaire.
En position de marche, le cliquet 12 glisse sur
l'extrémité 18a de la butée 18.Figure 7 shows an embodiment in
which the
Dans la forme d'exécution selon la figure 8, le doigt
de déverrouillage est constitué par l'extrémité 20a
d'un poussoir 20 monté sur un ressort 21. Un
verrouillage du poussoir 20 par rotation en position
enfoncée pourrait être aisément réalisé.In the embodiment according to Figure 8, the finger
release consists of the
Dans la forme d'exécution représentée aux figures 9 et
10, on retrouve un cliquet 12 coopérant avec une butée
18 formée sur le collier 2. La butée 18 est renforcée
par une pièce métallique 22 fixée au collier 2 par deux
rivets représentés par leurs axes 23, de chaque côté
d'une découpe 24 ouverte vers le bas. Le déverrouillage
est assuré par une bascule 25 en matière plastique logée
sans jeu dans une découpe 27 du collier 2 et articulée
autour d'un axe horizontal 26 sur la pièce métallique
22 dont les rivets de fixation sont donc situés
de chaque côté de la découpe 27. La bascule 25 présente
deux extrémités en forme de poussoirs 25a et 25b
actionnables de l'extérieur du collier 2. Le poussoir
inférieur 25a fait saillie vers l'intérieur du collier
et constitue le doigt de déverrouillage. L'absence de
jeu entre la bascule 25 et la découpe 27 assure, d'une
part, l'étanchéité et, d'autre part, le maintien par
frottement de la bascule dans la position choisie.In the embodiment shown in Figures 9 and
10, there is a
Dans la position représentée à la figure 2, le cliquet
12 est en butée contre l'extrémité de la pièce métallique
22 et le collier 2 est verrouillé en position de
descente.In the position shown in Figure 2, the
Une pression sur le poussoir 25a a pour effet d'écarter
le cliquet 12 de la pièce métallique 22 et de la butée
18 et donc de déverrouiller le collier 2 qui peut basculer
comme représenté à la figure 10. La bascule 25
est plus étroite que la découpe 24 dans la pièce métallique
22, de telle sorte que cette pièce métallique 22
n'empêche pas la bascule de tourner suffisamment pour
repousser et maintenir à coup sûr le cliquet 12 hors de
la trajectoire de la butée 18.Pressing the
