Abstract

This ski boot of semi-rigid synthetic material has a lower portion (3) comprising the sole and at least one pair of opposite flaps (11, 12, 13, 14) controlled by means of a foot-tightening system. The flaps are covered by a vamp (5) attached or not to the front quarter (4) of the boot shaft. This front quarter (4) is allowed to bend forwards with respect to the vamp (5) and bears against a resilient member (29) mounted on or under the vamp so as to provide an elastic flexion of which the elasticity is adjustable. With this construction the skier's foot is properly held in the boot without impairing the boot tightness.

Description

La présente invention a pour objet une chaussure de ski comportant une coque en matière synthétique semi-rigide constituée d'une partie inférieure comprenant la semelle et entourant le pied et le talon et d'une tige en deux parties, respectivement antérieure et postérieure, articulées sur la partie inférieure, et comprenant un organe élastique s'opposant à la flexion de la partie antérieur de la tige vers l'avant, et des moyens de tenue du pied situés à l'intérieur de la coque.The present invention relates to a ski boot comprising a shell of semi-rigid synthetic material consisting of a lower part comprising the sole and surrounding the foot and the heel and a rod in two parts, respectively anterior and posterior, articulated on the lower part, and comprising an elastic member opposing the bending of the front part of the rod towards the front, and means for holding the foot located inside the shell.

Une chaussure de ce type, communément appelée chaussure à chaussage par l'arrière en raison de la possibilité de faire basculer en arrière la partie postérieure de la tige, est décrite par exemple dans le brevet FR 2 345 097. Cette chaussure est constituée d'une coque rigide entourant le pied. Elle est du type à volume fixe par opposition aux chaussures dites du type à volume variable dans lesquelles l'empeigne peut être resserrée pour maintenir correctement le pied. Le volume de cette partie de la coque ne pouvant être réduit, le pied est maintenu au moyen d'un dispositif intérieur comportant une plaque d'appui épousant la forme du cou-de-pied et fixée au capot ou au chausson intérieur, et des câbles permettant d'exercer une traction diagonale sur cette plaque d'appui en direction du talon de manière à serrer le pied dans le logement du talon. Le bon maintien du pied dépend par conséquent presque entièrement de la bonne adaptation du talon du skieur à son logement dans la chaussure. La partie antérieure du pied n'est elle-même pas du tout tenue et dans le cas d'un pied étroit, le jeu du pied à l'intérieur de la chaussure peut être relativement grand et rendre la conduite du ski difficile.A shoe of this type, commonly called a shoe with a rear boot due to the possibility of tilting the rear part of the upper back, is described for example in patent FR 2 345 097. This shoe consists of a rigid shell surrounding the foot. It is of the fixed volume type as opposed to the shoes known as the variable volume type in which the upper can be tightened to properly maintain the foot. As the volume of this part of the shell cannot be reduced, the foot is maintained by means of an interior device comprising a support plate conforming to the shape of the instep and fixed to the hood or to the interior liner, and cables allowing to exert a diagonal traction on this support plate in the direction of the heel so as to clamp the foot in the heel housing. Proper support of the foot therefore depends almost entirely on the proper adaptation of the skier's heel to its accommodation in the shoe. The front part of the foot itself is not at all held and in the case of a narrow foot, the play of the foot inside the boot can be relatively large and make driving the ski difficult.

Ce problème n'existe pas dans les chaussures dont l'empeigne est munie d'oreilles susceptibles d'être serrées par un système de boucles, mais de telles chaussures, utilisées antérieurement aux chaussures à coque, laissent trop facilement pénétrer la neige et l'eau.This problem does not exist in shoes the upper of which is provided with ears capable of being tightened by a system of buckles, but such shoes, used before the shoes with shells, allow too easily to penetrate the snow and the water.

La présente invention a pour but de réaliser une chaussure à coque dont l'intérieur présente un volume variable, c'est-à-dire, la possibilité d'adapter les dimensions transversales intérieures de la chaussure aux dimensions du pied et par conséquent d'assurer un bon maintien du pied.The object of the present invention is to produce a shell shoe whose interior has a variable volume, that is to say, the possibility of adapting the internal transverse dimensions of the shoe to the dimensions of the foot and consequently of provide good foot support.

A cet effet, la chaussure selon l'invention est caractérisée par le fait que la partie de la coque recouvrant le pied est constituée d'un part d'au moins une paire d'oreilles opposées solidaires de la semelle et d'autre part d'un capot recouvrant lesdites oreilles et toute la partie antérieure du pied, et présentant des moyens de maintien dudit organe élastique de flexion.To this end, the shoe according to the invention is characterized in that the part of the shell covering the foot consists on the one hand of at least one pair of opposite ears secured to the sole and on the other hand of 'a cover covering said ears and the entire front part of the foot, and having means for holding said elastic bending member.

Les oreilles sont serrées autour du pied au moyen d'un système de serrage adéquat, par exemple un câble de traction fixé à l'extrémité d'une des oreilles et passant sur l'autre oreille.The ears are tightened around the foot by means of a suitable clamping system, for example a traction cable fixed at the end of one of the ears and passing over the other ear.

De manière à avoir un bon maintien du pied, on utilisera de préférence deux paires d'oreilles serrées chacune par un système de serrage de manière à obtenir un serrage en deux points. Si l'on utilise des câbles, les deux câbles pourront être tendus par un levier commun.In order to have a good support of the foot, one will preferably use two pairs of ears tightened each by a tightening system so as to obtain a tightening in two points. If cables are used, the two cables can be tensioned by a common lever.

Les. oreilles n'ont pas besoin d'entourer complètement le pied, étant donné que l'étanchéité est assurée par le capot. Il est donc possible de donner une grande liberté aux oreilles de manière à faciliter le serrage.The. ears do not need to completely surround the foot, since the seal is provided by the hood. It is therefore possible to give great freedom to the ears so as to facilitate tightening.

Selon une forme d'exécution de l'invention le capot est venu d'une pièce avec la partie antérieure de la tige et la saillie solidaire de la partie antérieure de la tige est munie d'une tête en forme de flèche accrochée sous tension au capot. Cette disposition a l'avantage de permettre de mouler la partie antérieure de la tige et le capot en position ouverte, c'est-à-dire la tête en forme de flèche détachée du capot, et d'accrocher la tête en forme de flèche au capot lors du montage, par flexion de la partie antérieure de la tige.According to one embodiment of the invention, the cover came in one piece with the front part of the rod and the projection integral with the front part of the rod is provided with an arrow-shaped head hung under tension at the hood. This arrangement has the advantage of making it possible to mold the front part of the rod and the cover in the open position, that is to say the arrow-shaped head detached from the cover, and to hang the arrow-shaped head. to the cover during assembly, by bending the front part of the rod.

Selon une autre forme d'exécution le bord supérieur transversal du capot est recouvert par la tige et l'organe élastique est situé entre le capot et la tige, entre une saillie du capot et une saillie de la tige.According to another embodiment, the transverse upper edge of the cover is covered by the rod and the elastic member is located between the cover and the rod, between a projection of the cover and a projection of the rod.

La chaussure selon l'invention présente en outre l'avantage de ne pas nécessiter de moyens de fixation d'une plaque d'appui à la coque ou au chausson intérieur.The shoe according to the invention also has the advantage of not requiring means for fixing a support plate to the shell or to the inner liner.

La chaussure représentée à la figure 1 est constituée d'une coque 1 en matière synthétique semi-rigide et d'un chausson intérieur 2 en matière souple et moelleuse.The shoe shown in Figure 1 consists of a shell 1 of semi-rigid synthetic material and an inner liner 2 of flexible and soft material.

La coque 1 est constituéee de trois parties : une partie inférieure 3 comprenant la semelle et entourant le talon et une tige constituée d'une partie antérieure 4 venue d'une pièce avec un capot 5 recouvrant le pied et d'une partie postérieure 6. La partie antérieure 4 de la tige est articulée sur la partie inférieure 3 de la coque en deux points opposés 8 et 9 tandis que la partie postérieure 6 de la tige est articulée sur la partie inférieure 3 en deux points opposés 7 et 10 situés légèrement en arrière des points 7 et 8. La partie pos térieure 6 de la tige peut être basculée vers l'arrière autour de ses articulations pour permettre le chaussage de la chaussure.The shell 1 is made up of three parts: a lower part 3 comprising the sole and surrounding the heel and a rod consisting of a front part 4 coming in one piece with a cover 5 covering the foot and a rear part 6. The front part 4 of the rod is articulated on the lower part 3 of the shell at two opposite points 8 and 9 while the rear part 6 of the rod is articulated on the lower part 3 at two oppo points ses 7 and 10 located slightly behind points 7 and 8. The rear part 6 of the upper can be tilted back around its joints to allow the shoe to be put on.

La partie inférieure 3 de la coque comprenant la semelle est munie de deux paires d'oreilles 11, 12 et 13, 14 venues d'une pièce, de fabrication, avec la semelle et assez minces pour être souples. Comme ceci ressort de la figure 2, la partie inférieure 3 de la coque se présente comme une sorte de sandale à forte semelle.The lower part 3 of the shell comprising the sole is provided with two pairs of ears 11, 12 and 13, 14 coming from a single piece, of manufacture, with the sole and thin enough to be flexible. As can be seen from Figure 2, the lower part 3 of the shell looks like a kind of sandal with a strong sole.

La partie antérieure 4 de la tige et le capot 5, venus d'une seule pièce, sont reliès par deux ponts latéraux 15 et 16 entre lesquels est formée une échancrure 17 s'étendant largement sur le cou-de-pied et permettant à la partie antérieure 4 de la tige de fléchir en avant relativement au capot 5. Lorsqu'elles sortent du moule, les parties 4 et 5 sont dans la position représentée aux figure 2 et 3. L'échancrure 17 est largement ouverte. Le bord inférieure de la partie 4 de la tige limitant l'échancrure 17 est muni d'une saillie axiale 18 présentant une tête 19 en forme de flèche et s'étendant sur presque toute la largeur de l'échancrure 17.Le bord inférieur de l'échancrure 17 faisant partie du capot 5 présente un rebord coudé 20 au milieu duquel est prévu un passage 21 dont la largeur est substantiellement inférieure à la plus grande largeur de la flèche 19.The front part 4 of the rod and the cover 5, coming in one piece, are connected by two lateral bridges 15 and 16 between which is formed a notch 17 extending widely over the instep and allowing the front part 4 of the rod to flex forward relative to the cover 5. When they come out of the mold, the parts 4 and 5 are in the position shown in FIGS. 2 and 3. The notch 17 is wide open. The lower edge of the part 4 of the rod limiting the notch 17 is provided with an axial projection 18 having an arrow-shaped head 19 and extending over almost the entire width of the notch 17. the notch 17 forming part of the cover 5 has a bent edge 20 in the middle of which a passage 21 is provided, the width of which is substantially less than the greatest width of the arrow 19.

Le capot 5 présente en outre une découpe rectangulaire 22 et sur son pourtour inférieur des ergots 23, 24, 25, 26, 27 et 28.The cover 5 also has a rectangular cutout 22 and on its lower periphery lugs 23, 24, 25, 26, 27 and 28.

Lors de l'assemblage des parties 3, 4 et 5 de la coque, on interpose entre la paire d'oreilles 13 et 14 et le capot 5 une bande élastique 29 et une languette support 30 destinés à soutenir la bande élastique 29. Le capot 5, la languette 30 et la partie 3 de la coque sont assujettis au moyen d'un élément de fixation non représenté traversant des trous 31, 32 et 33 respectivement prévus dans ces différentes parties. Les ergots 23 à 28 viennent s'engager dans des trous de positionnement 34, 35 et 36 de la partie inférieure 3 de la coque. On fléchit ensuite la partie antérieure 4 de la tige vers l'avant de manière à pouvoir engager latéralement la saillie 18 à travers le passage 21. La tête 19 de cette saillie vient alors s'accrocher derrière le rebord 20 comme représenté à la figure 4. Dans cette position, l'extrémité de la tête 19 vient en appui contre la bande 29. Cette bande 29 n'est pas homogène. Elle présente une partie intérieure 37 en matière relativement très compressible et de largeur variable. La bande 29 présente dès lors transversalement, dans la direction de la flèche 19, un taux de compressibilité variable. Elle est munie d'une saillie 38 traversant la découpe 22 et permettant de déplacer la bande 29 transversalement à la chausssure de manière à per- metre de modifier le point d'appui de la tête 19 sur la bande c'est-à-dire de modifier la résistance à la flexion de la tige de la chaussure.L'échancrure 17 est fermée par un soufflet 39 dont les bords sont soudés aux bords de l'échancrure.During the assembly of parts 3, 4 and 5 of the shell, an elastic band 29 and a support tongue 30 intended to support the elastic band 29 are interposed between the pair of ears 13 and 14 and the cover 5. 5, the tongue 30 and the part 3 of the shell are secured by means of a fixing element (not shown) passing through holes 31, 32 and 33 respectively provided in these different parts. The pins 23 to 28 engage in positioning holes 34, 35 and 36 of the lower part 3 of the shell. The front part 4 of the rod is then bent forward so that the projection 18 can be engaged laterally through the passage 21. The head 19 of this projection then comes to hang behind the flange 20 as shown in FIG. 4 In this position, the end of the head 19 bears against the strip 29. This strip 29 is not homogeneous. It has an inner part 37 of relatively very compressible material and of variable width. The strip 29 therefore has transversely, in the direction of arrow 19, a variable compressibility rate. It is provided with a projection 38 passing through the cutout 22 and making it possible to move the band 29 transversely to the shoe so as to modify the fulcrum of the head 19 on the band, that is to say to modify the resistance to bending of the upper of the shoe. The notch 17 is closed by a bellows 39 whose edges are welded to the edges of the notch.

Le serrage des oreilles 11 à 14 autour du pied est assuré ici par deux câbles 40 et 41 dont une extrémité est fixée respectivement aux oreilles 11 et 13 et qui sont guidés sur l'oreille opposée et s'étendent vers l'arrière de la chaussure à travers des moyens de guidage constitués par exemple par une gaine de câble de bicyclette. Les autres extrémités de ces câbles 40 et 41 sont attachées à un tendeur commun ou à deux tendeurs indépendants, non représentés, montés sur le dos de la partie postérieure 6 de la tige, de manière connue en soi.The clamping of the ears 11 to 14 around the foot is ensured here by two cables 40 and 41, one end of which is fixed respectively to the ears 11 and 13 and which are guided on the opposite ear and extend towards the rear of the shoe through guide means constituted for example by a bicycle cable sheath. The other ends of these cables 40 and 41 are attached to a common tensioner or to two independent tensioners, not shown, mounted on the back of the rear part 6 of the rod, in a manner known per se.

Quant à la tige de la chaussure elle est soit fermée par une boucle conventionnelle non représentée ou un collier ou un dispositif à câble pouvant être actionné par le même tendeur que le tendeur actionnant les câbles 40 et 41.As for the upper of the shoe, it is either closed by a conventional buckle (not shown) or a collar or a cable device which can be actuated by the same tensioner as the tensioner actuating the cables 40 and 41.

On se rend compte que grâce à la présence des paires d'oreilles 11, 12 et 13, 14, il est possible d'obtenir une excellente tenue du pied, non seulement par le maintien du talon, mais par l'adaptation du volume intérieur de la chaussure au volume du pied.We realize that thanks to the presence of the pairs of ears 11, 12 and 13, 14, it is possible to obtain an excellent hold of the foot, not only by maintaining the heel, but by adapting the interior volume from shoe to foot volume.

Selon une variante d'exécution le capot et la partie antérieure de la tige pourraient être constitués de deux pièces articulées l'une à l'autre latéralement. D'autre part, les points d'articulation 7 et 9 des parties antérieure et postérieure de la tige pourraient être confondus.According to an alternative embodiment, the cover and the front part of the rod could consist of two parts articulated to one another laterally. On the other hand, the articulation points 7 and 9 of the anterior and posterior parts of the rod could be confused.

Quant au soufflet 39 il pourrait être fixé par encliquetage ou par un moyen mécanique auxiliaire tels que des rivets.As for the bellows 39, it could be fixed by snap-fastening or by an auxiliary mechanical means such as rivets.

La chaussure représentée aux figures 5 à 7 est constituée d'une coque 42 en matière synthétique semi-rigide et d'un chausson intérieur 43 en matière souple et moelleuse.The shoe shown in Figures 5 to 7 consists of a shell 42 of semi-rigid synthetic material and an inner liner 43 of flexible and soft material.

La coque est constituée de quatre parties : une partie inférieure 44 comprenant la semelle 45 et entourant le talon, un capot 46 recouvrant le pied et une tige constituée d'une partie antérieure 47 et d'une partie postérieure 48. Les deux parties 47 et 48 de la tige sont articulées sur la partie inférieure 44 au moyen de deux rivets opposés, tel que le rivet 49 invisible à la figure 5, ces rivets fixant également le capot 46. Cette articulation permet à la partie postérieure de la tige postérieure de la tige 48 de basculer en arrière pour permettre l'ouverture de la chaussure et son chaussage par l'arrière. L'articulation de la partie antérieure 47 de la tige assure une certaine flexion en avant de le tige, comme ceci sera décrit plus loin.The shell consists of four parts: a lower part 44 comprising the sole 45 and surrounding the heel, a cover 46 covering the foot and a rod consisting of an anterior part 47 and a posterior part 48. The two parts 47 and 48 of the rod are articulated on the lower part 44 by means of two opposite rivets, such as the rivet 49 invisible in FIG. 5, these rivets also fixing the cover 46. This articulation allows the rear part of the rear rod of the rod 48 to tilt back to allow the opening of the shoe and its fitting from the rear. The articulation of the front part 47 of the rod provides a certain bending in front of the rod, as will be described later.

La partie inférieure 44 a l'aspect d'une chaussure de marche à tige basse. Elle est munie de deux oreilles 50 et 51 venues d'une pièce de fabrication avec la semelle 45 et se recouvrant légèrement. Le bout de chausssure 52 est fermé. Les oreilles 50 et 51 montent relativement haut sur le cou-de-pied, de manière à recouvrir ce cou-de-pied. En deux points 53 et 54 de l'oreille 50 sont fixées les extrémités de deux câbles 55 et 56 passant respectivement autour d'un bossage 57 et 58 formé à la base de l'oreille 51, ces bossages servant de renvoi aux câbles 55 et 56 dont l'autre extrémité est reliée à l'arrière à un tendeur 50 monté sur la partie postérieure 48 de la tige et au moyen duquel un serrage des oreilles 50 et 51 peut être assuré. Les oreilles 50 et 51 peuvent être relativement mince et souple de manière à bien s'adapter à la forme du pied. Les bossages 57 et 58 assurent une traction transversale adéquate sur l'oreille 50.The lower part 44 has the appearance of a walking shoe with a low upper. It is provided with two ears 50 and 51 coming from a workpiece with the sole 45 and slightly overlapping. The toe of shoe 52 is closed. The ears 50 and 51 rise relatively high on the instep, so as to cover this instep. At two points 53 and 54 of the ear 50 are fixed the ends of two cables 55 and 56 passing respectively around a boss 57 and 58 formed at the base of the ear 51, these bosses serving as a reference to the cables 55 and 56, the other end of which is connected at the rear to a tensioner 50 mounted on the rear part 48 of the rod and by means of which the ears 50 and 51 can be clamped. The ears 50 and 51 can be relatively thin and flexible so as to adapt well to the shape of the foot. The bosses 57 and 58 provide adequate transverse traction on the ear 50.

La partie inférieure 44 présente sur la plus grande partie de son pourtour, au-dessus de la semelle 45, une portée 60 et au-dessus de cette portée une nervure 61 pour la fixation du capot 46. Le capot 46 recouvre complètement la partie avant du pied, c'est-à-dire les oreilles 50 et 51 et le bout de pied 52. Son bord inférieur 62 est muni d'un coude intérieur 63 (figure 7) par lequel le capot 46 vient s'accrocher derrière la nervure 61 de la partie inférieure, tandis que le bord inférieur 62 du capot vient au niveau de la portée 60. Le bord supérieur transversal du capot 46 présente un rebord saillant 64 engagé derrière une nervure intérieure 65 de la partie antérieure 47 de la tige, de telle sorte que le rebord saillant 64 du capot forme une butée limitant le pivotement en arrière de la partie antérieure 47 de la tige (figure 7). En avant du rebord saillant 64 du capot, celui-ci présente une saillie 66 relativement étroite présentant une face arrondie 67 perpendiculaire au capot en regard du rebord saillant 64 du capot et une face avant inclinée en formant un angle faible avec la surface du capot. Le bord inférieur de la partie antérieure 47 de la tige recouvre cette face avant inclinée et vient en contact avec le capot 46. Entre la saillie 66 et la nervure intérieur 65 de la partie antérieure 47 de la tige est montée une bande 68 présentant une élasticité variable en compression transversale. Cette élasticité variable est obtenue ici par un soufflet 69 en forme de V reliant les bords d'une échancrure de forme correspondante prévue longitudinalement dans la bande 68. Cette bande 68 est munie d'une saillie 70 par laquelle la bande peut être déplacée transversalement, la saillie 70 pouvant être atteinte et manoeuvrée à travers une découpe 71 prévue dans la partie antérieure 47 de la tige. Lorsque la tige de la chaussure fléchit vers l'avant, la bande 68 est comprimée entre le bossage 66 du capot et la nervure 65 de la partie antérieure 47 de la tige. En modifiant la position de la bande 68 on modifie la résistance de la chaussure à la flexion de la tige. Lorsque la saillie 70 est dans sa position extrême près du centre de la chaussure, l'élasticité à la flexion est nulle, tandis que lorsque la saillie 70 est dans son autre position extrême en direction du rivet 49, la bande 68 n'est plus en face de la saillie 66 et la tige ne rencontre plus la résistance de la bande 68. La compression variable de la bande peut bien entendu être obtenue par d'autre moyen, notamment en utilisant une combinaison de deux matériaux de rigidités différentes.The lower part 44 has over most of its periphery, above the sole 45, a surface 60 and above this surface a rib 61 for fixing the cover 46. The cover 46 completely covers the front part of the foot, that is to say the ears 50 and 51 and the end of the foot 52. Its lower edge 62 is provided with an inner elbow 63 (FIG. 7) by which the cover 46 is hooked behind the rib 61 of the lower part, while the lower edge 62 of the cover comes at the level of the bearing surface 60. The transverse upper edge of the cover 46 has a protruding rim 64 engaged behind an internal rib 65 of the front part 47 of the rod, such that the projecting rim 64 of the cover forms a stop limiting the pivoting behind the front part 47 of the rod (FIG. 7). In front of the protruding edge 64 of the cover, the latter has a relatively narrow projection 66 having a rounded face 67 perpendicular to the cover opposite the protruding edge 64 of the cover and a front face inclined at a slight angle with the surface of the cover. The lower edge of the front part 47 of the rod covers this inclined front face and comes into contact with the cover 46. Between the projection 66 and the internal rib 65 of the front part 47 of the rod is mounted a band 68 having an elasticity variable in transverse compression. This variable elasticity is obtained here by a V-shaped bellows 69 connecting the edges of a correspondingly shaped notch provided longitudinally in the strip 68. This strip 68 is provided with a projection 70 by which the strip can be moved transversely, the projection 70 being able to be reached and maneuvered through a cutout 71 provided in the front part 47 of the rod. When the upper of the shoe flexes forward, the strip 68 is compressed between the boss 66 of the cover and the rib 65 of the front part 47 of the upper. By modifying the position of the band 68, the resistance of the shoe to the flexion of the upper is modified. When the projection 70 is in its extreme position near the center of the shoe, the elasticity in flexion is zero, while when the projection 70 is in its other extreme position towards the rivet 49, the band 68 is no longer opposite the projection 66 and the rod no longer meets the resistance of the strip 68. The variable compression of the strip can of course be obtained by other means, in particular by using a combination of two materials of different rigidities.

La tige de la chaussure est fermée par un dispositif non représenté qui peut être par exemple une boucle conventionnelle, un collier connu ou un dispositif à câble actionné par le tendeur 59 actionnant les câbles 55 et 56, tel que décrit par exemple dans diverses publiations récentes.The upper of the shoe is closed by a device (not shown) which can be for example a conventional buckle, a known collar or a cable device actuated by the tensioner 59 actuating the cables 55 and 56, as described for example in various recent publications. .

Grâce à la présence des oreilles 50 et 51 et du capot 46, la chaussure selon l'invention se présente extérieurement comme une chaussure à bas de coque rigide avec les avantages que présente un tel type de chaussure sur le plan de l'etanchéité et de la résistance mécanique, tandis qu'intérieurement la chaussure présente un volume variable et peut être serrée comme une chaussure de marche usuelle.Thanks to the presence of the ears 50 and 51 and of the cover 46, the shoe according to the invention presents itself externally as a shoe with a low rigid shell with the advantages that such a type of shoe has in terms of sealing and mechanical resistance, while internally the shoe has a variable volume and can be tightened like a normal walking shoe.

En variante la partie postérieure de la tige 48 pourrait être articulée en deux points différents des rivets. 49. Des rivets supplémentaires pourraient bien entendu être prévus pour fixer le capot 46 à la semelle en plus de la nervure 61 ou en lieu et place de cette nervure.As a variant, the rear part of the rod 48 could be articulated at two different points from the rivets. 49. Additional rivets could of course be provided to fix the cover 46 to the sole in addition to the rib 61 or in place of this rib.

Une seconde forme d'exécution de l'invention est représentée aux figures 8 et 9. Cette seconde forme d'exécution présente de nombreuses caractéristiques communes avec la première forme d'exécution et, afin d'éviter une répétition inutile de la description, les parties de cette seconde forme d'exécution correspondant aux parties de la première forme d'exécution ont été désignées par les mêmes références accompagnées du signe '. On se bornera dès lors à décrire ce qui, dans cette seconde forme d'exécution, diffère de la première forme d'exécution. Cette différence réside dans la manière dont est réalisée la partie avant de la chaussure, plus précisément dans la manière dont le capot 46' recouvre la partie inférieure de la coque comprenant la semelle 45' et la fixation de ce capot 46'. Comme ceci est particulièrement visible à la figure 9, la partie avant de la semelle 45' avec ses deux oreilles 50' et 51' est tronquée selon un plan sensiblement vertical et transversal à la chaussure 72 en laissant toutefois subsister une languette horizontale 73 s'étendant vers l'avant au niveau de la face supérieure de la semelle 45'. La semelle proprement dite ne s'étend en outre que sur les deux tiers environ de la longueur de la chaussure à compter du talon, la partie restante 74 formant une sorte de manchon surélevé au-dessus du plan 75 de la semelle. Le capot 46', quant à lui, forme une sorte de capuchon ou fourreau dans lequel vient s'introduire et s'emboîter le bas de coque 45' dans le sens de la flèche F. Le capot 46' comprend dès lors la partie antérieure 76 de la semelle, qui vient se placer dans le prolongement de la partie 75 de la semelle, et le bout extérieur de la chaussure 77. La languette 73 vient s'engager dans un logement formé par moulage dans l'extrémité du capot 46' à la hauteur de l'extrémité 77. Les bords latéraux 78 et 79 du capot 46' viennent se placer en face d'une portée oblique 79 et d'une portée identique correspondante prévue de l'autre côté du bas de coque 45'. Le capot 46' et le bas de coque 45' sont en outre fixés comme précédemment par des rivets 49' traversant des trous 80 et 81 prévus à cet effet de chaque côté de la chaussure. La rigidité de cette fixation pourrait bien entendu être encore renforcée au moyen d'une seconde paire de rivets distincts de l'articulation de la tige de la chaussure. Cette seconde forme d'exécution présente certains avantages par rapport à la première forme d'exécution. La cohésion, l'assemblage et l'étanchéité de la chaussure au niveau du pied est améliorée étant donné que toute la partie avant du pied est constitué par une coque étanche en une pièce. D'autre part, les oreilles 50 et 51' sont totalement indépendantes l'une de l'autre, ce qui permet d'assurer un serrage plus précis et plus efficace de la partie avant du pied. En outre, le moulage, ainsi que l'extraction du bas de coque 45' sont facilités. Les bossages 57 et 58 pourraient être remplacés par des rainures de guidage.A second embodiment of the invention is shown in Figures 8 and 9. This second embodiment has many features in common with the first embodiment and, in order to avoid unnecessary repetition of the description, the parts of this second embodiment corresponding to the parts of the first embodiment have been designated by the same references accompanied by the sign '. We will therefore limit ourselves to describing what, in this second embodiment, differs from the first embodiment. This difference lies in the way in which the front part of the shoe is produced, more precisely in the way in which the cover 46 'covers the lower part of the shell comprising the sole 45' and the fixing of this cover 46 '. As this is particularly visible in FIG. 9, the front part of the sole 45 ′ with its two ears 50 ′ and 51 ′ is truncated in a substantially vertical plane and transverse to the shoe 72, however leaving a horizontal tongue 73 s ′ extending forwards at the level of the upper face of the sole 45 '. The sole itself also extends only over about two-thirds of the length of the shoe from the heel, the remaining part 74 forming a sort of raised sleeve above the plane 75 of the sole. The cover 46 ', for its part, forms a sort of cap or sheath into which is inserted and fitted the bottom of the shell 45' in the direction of the arrow F. The cover 46 'therefore includes the front part 76 of the sole, which is placed in the extension of the part 75 of the sole, and the outer end of the shoe 77. The tongue 73 engages in a housing formed by molding in the end of the cover 46 ' at the height of the end 77. The lateral edges 78 and 79 of the cover 46 'are placed opposite an oblique bearing 79 and a corresponding identical bearing provided on the other side of the bottom of the shell 45'. The hood 46 'and the shell bottom 45' are further fixed as above by rivets 49 'passing through holes 80 and 81 provided for this purpose on each side of the shoe. The rigidity of this binding could of course be further enhanced by means of a second pair of rivets distinct from the articulation of the upper of the shoe. This second embodiment has certain advantages over the first embodiment. The cohesion, assembly and sealing of the shoe at the level of the foot is improved since the entire front part of the foot consists of a one-piece waterproof shell. On the other hand, the ears 50 and 51 'are completely independent of each other, which ensures more precise and effective clamping of the front part of the foot. In addition, the molding, as well as the extraction of the bottom shell 45 'are facilitated. The bosses 57 and 58 could be replaced by guide grooves.
