Abstract

The sports boot comprises uppers (4,5) which cover vertical extensions from a base shell (1) in the ankle zone (23). The shell base has a longitudinal opening (17) on the top provided with a pair of transverse flaps (13,15). The flaps are each partially separated from the lateral vertical extensions (12) by slits (19) parallel to the longitudinal opening above the base. The slits determine, in the front part of the vertical extensions, the edges (24,26) of a U shaped indentation and a tongue (14,16) on each flap. The tongues are fitted to the flaps at a level corresponding to the bending fold (20) beyond the parts covered by the uppers.

Description

La présente invention concerne une chaussure de sport du type dit "à coque rigide" qui se ferme et s ouvre, au moins sur le dessus du pied, à l'aide de rabats transversaux relativement flexibles qui se recouvrent partiellement.The present invention relates to a sports shoe of the so-called "rigid shell" type which closes and opens, at least on the top of the foot, by means of relatively flexible transverse flaps which partially overlap.

Des chaussures de sport de ce type, telles que les chaussures de ski décrites dans les brevets FR 2 129 074, US 4 974 346, US 5 295 316 et le modèle d'utilité japonais H03-17685, par exemple, présentent une base de coque qui entoure le pied du porteur et une tige qui maintient le bas de jambe de ce dernier, des dispositifs de serrage et/ou de fermeture associés à ces parties de la chaussure assurant l'ajustement sur le pied et le bas de jambe. Dans ces chaussures, la tige, qu'elle soit en une ou plusieurs parties, recouvre des extensions verticales venues de la base de coque jusque dans la zone correspondant à la cheville du porteur. Ces extensions verticales sont destinées à garantir une certaine étanchéité entre la base de coque et la tige, à permettre un ajustement et un serrage différencié entre ces parties constitutives de la chaussure, à répartir sur une certaine surface les efforts exercés localement par les dispositifs de serrage, et, éventuellement, à faciliter le passage du pied lors du chaussage et du déchaussage. Pour ce faire, la base de coque est ouverte longitudinalement sur le dessus et est pourvue d'au moins une paire de rabats transversaux se chevauchant et prolongeant ses parois latérales sur le dessus du pied jusque dans la zone de la cheville où ils constituent, pour partie, ses extensions verticales. Comme enseigné, l'ajustement de ces chaussures sur le pied et le bas de jambe s'effectue par réduction du volume de la tige et de la base de coque au moyen des dispositifs de serrage situés à l'extérieur. Dans le cas de la base de coque plus particulièrement, cette réduction du volume est obtenue en provoquant le rapprochement des rabats transversaux entre eux qui, par déformation, s'abaissent et se resserrent plus ou moins vers le pied selon la force exercée par les dispositifs de serrage en entraînant conjointement la déformation au moins partielle, et dans le même sens, des parois latérales de la base de coque dont ils sont issus. Cette manière de réaliser l'ajustement et le serrage de la chaussure sur le pied a l'avantage de permettre un excellent maintien car on adapte réellement le volume intérieur de la base de coque à celui extérieur du pied, et ce avec précision, en employant de préférence des dispositifs de serrage connus dotés d'un réglage micrométrique. Cependant, du fait de la superposition des rabats, il s'ensuit une augmentation relativement importante de la pression s'exerçant entre eux à l'endroit où ils se recouvrent, et ainsi une augmentation de leur rigidité transversale d'autant plus accentuée qu'ils sont courbés sur le pied et dans la zone correspondant au pli-de-flexion où ils forment l'équivalent d'un demitube cintré approximativement à 90°, comme c'est le cas dans les chaussures des documents FR 2 129 074, US 5 295 316 et JP H03-17685 cités précédemment.Sports shoes of this type, such as the ski boots described in patents FR 2 129 074, US 4 974 346, US 5 295 316 and the Japanese utility model H03-17685, for example, have a base of shell which surrounds the wearer's foot and a rod which holds the lower leg of the latter, tightening and / or closing devices associated with these parts of the shoe ensuring adjustment on the foot and the lower leg. In these shoes, the upper, whether in one or more parts, covers vertical extensions from the shell base to the zone corresponding to the wearer's ankle. These vertical extensions are intended to guarantee a certain seal between the shell base and the upper, to allow a differentiated adjustment and tightening between these constituent parts of the shoe, to distribute over a certain surface the forces exerted locally by the tightening devices , and possibly facilitate the passage of the foot during putting on and taking off. To do this, the shell base is open longitudinally on the top and is provided with at least one pair of overlapping transverse flaps and extending its side walls on the top of the foot as far as the ankle area where they constitute, for part, its vertical extensions. As taught, the adjustment of these shoes on the foot and the lower leg is effected by reducing the volume of the upper and the shell base by means of the clamping devices located outside. In the case of the shell base more particularly, this reduction in volume is obtained by bringing the transverse flaps together which, by deformation, lower and tighten more or less towards the foot depending on the force exerted by the devices tightening by jointly causing at least partial deformation, and in the same direction, of the side walls of the shell base from which they originate. This way of adjusting and tightening the shoe on the foot has the advantage of allowing excellent support since the interior volume of the shell base is really adapted to that of the outside of the foot, and this precisely, by using preferably known clamping devices with micrometric adjustment. However, due to the superposition of the flaps, there follows a relatively significant increase in the pressure exerted between them at the place where they overlap, and thus an increase in their transverse rigidity all the more accentuated as they are curved on the foot and in the zone corresponding to the bending fold where they form the equivalent of a half-tube bent approximately 90 °, as is the case in the shoes of documents FR 2 129 074, US 5,295,316 and JP H03-17685 cited above.

Or, c'est précisément dans cette zone correspondant au pli de flexion qu'il est nécessaire de disposer d'un maximum de souplesse pour réaliser un ajustement optimum de l'enveloppement des rabats au-dessus du cou-de-pied, ne pas influencer les caractéristiques de flexion de la tige par rapport à la base de coque, et permettre un serrage différencié entre ces parties constitutives de la chaussure. Il est évident que c'est également dans cette zone qu'il est nécessaire de pouvoir écarter largement les rabats pour introduire ou sortir le pied lorsqu'il s'agit d'une chaussure classique du type à "entrée par l'avant", telle que celle décrite dans le document FR 2 129 074. Une solution partielle à ces problèmes est décrite dans le brevet US 4 974 346. En effet, selon ce document, la chaussure de sport, comportant une tige qui recouvre des extensions verticales venues de la base de coque dans la zone correspondant à la cheville, présente une base de coque ouverte longitudinalement sur le dessus et pourvue à l'endroit de son ouverture de deux paires de rabats transversaux qui prolongent ses parois latérales et qui se chevauchent. Elle se caractérise, entre autres, par le fait, d'une part, que la base de coque présente sur le devant dans la zone du pli de flexion une fente ouverte transversalement qui sépare la partie inférieure qui entoure le pied de celle supérieure qui s'étend partiellement sur le bas de jambe, et d'autre part, que des languettes sont fixées sur les rabats inférieurs pour servir de joint à la fente. Par ces dispositions, la tige peut être serrée indépendamment de la base de coque tout en préservant l'étanchéité entre ces parties de la chaussure. Il ressort toutefois que la superposition des extensions verticales antérieures venues des parois latérales de la base de coque avec celles des languettes d'étanchéité constitue une structure stratifiée qui augmente notablement la rigidité de la base de coque dans la zone correspondant au pli de flexion, ce qui gêne et influence la flexion de la tige par rapport à la base de coque. Par ailleurs, la réalisation de la fente transversale ne dispense pas de devoir écarter largement les extensions verticales antérieures qui prolongent les parois latérales de la base de coque, ainsi que les languettes d'étanchéité, pour le passage du pied au chaussage et déchaussage. Enfin, du fait du rajout des languettes d'étanchéité dans la fente sur les rabats transversaux, la solution enseignée par ce document se révèle d'une certaine complexité qui grève les coûts de fabrication.However, it is precisely in this zone corresponding to the bending fold that it is necessary to have maximum flexibility to achieve an optimum adjustment of the wrapping of the flaps above the instep, not influence the flexural characteristics of the upper relative to the shell base, and allow differentiated tightening between these constituent parts of the shoe. It is obvious that it is also in this zone that it is necessary to be able to widely spread the flaps to introduce or take out the foot when it is a conventional shoe of the type with "front entry", such as that described in document FR 2 129 074. A partial solution to these problems is described in US Patent 4,974,346. Indeed, according to this document, the sports shoe, comprising a rod which covers vertical extensions coming from the shell base in the zone corresponding to the ankle, has a shell base open longitudinally on the top and provided at the point of its opening with two pairs of transverse flaps which extend its side walls and overlapping. It is characterized, inter alia, by the fact, on the one hand, that the shell base has on the front in the area of the bending fold a slit open transversely which separates the lower part which surrounds the foot from the upper one which s 'partially extends over the lower leg, and secondly, that tabs are attached to the lower flaps to serve as a seal to the slot. By these provisions, the upper can be tightened independently of the shell base while preserving the seal between these parts of the shoe. However, it appears that the superposition of the anterior vertical extensions coming from the side walls of the shell base with those of the sealing tongues constitutes a laminated structure which notably increases the rigidity of the shell base in the zone corresponding to the bending fold, this which hinders and influences the bending of the rod relative to the shell base. Furthermore, the realization of the transverse slot does not dispense with having to widely spread the anterior vertical extensions which extend the side walls of the hull base, as well as the sealing tongues, for the passage of the foot to the boot and shoeing. Finally, due to the addition of the sealing tabs in the slot on the transverse flaps, the solution taught by this document proves to be of a certain complexity which increases the manufacturing costs.

La présente invention se propose de remédier à ces différents problèmes par une solution simple et efficace qui permette :

  • de préserver une étanchéité correcte entre la tige et la base de coque,
  • de différencier le serrage entre la tige et la base de coque,
  • d'ajuster avec précision l'enveloppement du pied dans la zone du pli de flexion,
  • de ne pas influencer les caractéristiques de flexion de la tige par rapport à la base de coque,
  • de faciliter le passage du pied lors du chaussage-déchaussage,
  • d'être particulièrement aisé et simple à fabriquer et à mettre en oeuvre,
  • de ne pas grèver les coûts de fabrication.
The present invention proposes to remedy these various problems by a simple and effective solution which allows:
  • to maintain a correct seal between the rod and the shell base,
  • to differentiate the tightening between the rod and the shell base,
  • to precisely adjust the wrapping of the foot in the area of the flexion fold,
  • not to influence the bending characteristics of the rod relative to the shell base,
  • to facilitate the passage of the foot during putting on and taking off,
  • to be particularly easy and simple to manufacture and to implement,
  • not to burden manufacturing costs.

Pour atteindre ces objectifs, la chaussure de sport, selon l'invention du type à coque rigide, comporte une tige qui recouvre des extensions verticales venues de la base de coque dans la zone correspondant à la cheville du porteur et la base de coque, réalisée avec une ouverture longitudinale sur le dessus, est pourvue d'au moins une paire de rabats transversaux, lesquels prolongent ses parois latérales et se chevauchent. La chaussure se caractérise par le fait que les rabats sont, chacun, partiellement séparés des extensions verticales et latérales venues de la base de coque par une fente débouchant vers le haut, et orientée sensiblement parallèlement à l'ouverture longitudinale du dessus de la base de coque. Les fentes déterminent ainsi dans la partie antérieure des extensions verticales de la base de coque une échancrure en forme générale de U dépourvue de rabats transversaux prolongeant les extensions verticales latérales de la base de coque, et, respectivement, une languette sur chaque rabat. Par conséquence, les languettes obtenues se chevauchent naturellement puisqu'elles constituent le prolongement des rabats et referment l'échancrure en forme de U, en préservant une étanchéité correcte entre la tige et la base de coque. Il ressort de cette construction que le serrage de la tige sur le bas de jambe du porteur rapproche les bords de l'échancrure qui sont situés dans la zone de la cheville sans entraîner les languettes qui, elles, sont solidaires des rabats à un niveau situé approximativement en correspondance du pli de flexion, soit hors des parties recouvertes par ladite tige. Cette construction permet donc de différencier le serrage entre la tige et la base de coque. Par ailleurs, du fait que les languettes sont en superposition simple entre elles et sur les bords de l'échancrure, et qu'elles ne sont plus reliées aux extensions verticales et latérales de la base de coque mais simplement aux rabats et sur une partie étroite de ceux-ci, donc peu courbée, la pression exercée par les dispositifs de serrage associés à la base de coque et/ou à la tige n'augmente pratiquement par leur rigidité et donc leur résistance à la flexion de la tige par rapport à la base de coque. Les caractéristiques initiales et/ou pré-réglées de flexion de la tige par rapport à la base de coque ne sont donc pas perturbées et/ou influencées par les efforts de serrage appliqués sur les languettes. Egalement, du fait de leur liaison sur une partie étroite des rabats, les languettes se trouvent dotées d'une grande flexibilité par rapport à ceux-ci et donc peuvent s'ajuster avec précision dans la zone du pli de flexion, assurant ainsi un enveloppement optimum de la partie du pied située en vis à vis. Il ressort à l'évidence que la flexibilité des languettes ainsi obtenues et la situation de ces dernières dans la zone antérieure de la base de coque échancrée au niveau du pli de flexion facilite grandement le passage du pied lors du chaussage-déchaussage.To achieve these objectives, the sports shoe according to the invention of the rigid shell type, comprises a rod which covers vertical extensions coming from the shell base in the zone corresponding to the wearer's ankle and the shell base, produced with a longitudinal opening on the top, is provided with at least one pair of transverse flaps, which extend its side walls and overlap. The shoe is characterized by the fact that the flaps are each partially separated from the vertical and lateral extensions coming from the shell base by a slot opening upwards, and oriented substantially parallel to the longitudinal opening of the top of the base. shell. The slots thus determine in the anterior part of the vertical extensions of the hull base a notch in the general U shape devoid of transverse flaps extending the lateral vertical extensions of the hull base, and, respectively, a tab on each flap. Consequently, the tabs obtained naturally overlap since they constitute the extension of the flaps and close the U-shaped notch, while preserving a correct seal between the rod and the shell base. It emerges from this construction that the tightening of the rod on the lower leg of the wearer brings the edges of the notch which are located in the ankle area without entraining the tabs which are integral with the flaps at a level located approximately in correspondence with the bending fold, or outside the parts covered by said rod. This construction therefore makes it possible to differentiate the tightening between the rod and the shell base. Furthermore, the fact that the tongues are in simple superposition between themselves and on the edges of the notch, and that they are no longer connected to the vertical and lateral extensions of the shell base but simply to the flaps and on a narrow part of these, therefore not very curved, the pressure exerted by the clamping devices associated with the shell base and / or with the rod practically increases by their rigidity and therefore their resistance to bending of the rod relative to the hull base. The initial and / or pre-set bending characteristics of the rod relative to the shell base are therefore not disturbed and / or influenced by the clamping forces applied to the tongues. Also, due to their connection on a narrow part of the flaps, the tongues are provided with great flexibility with respect to them and therefore can be adjusted precisely in the area of the bending fold, thus ensuring a wrapping optimum of the part of the foot opposite. It is evident that the flexibility of the tabs thus obtained and the situation of the latter in the anterior zone of the shell base indented at the level of the flexion fold greatly facilitates the passage of the foot during the putting on and taking off.

Enfin, en obtenant directement les languettes dans le prolongement des rabats qui s'étendent sur le dessus de la base de coque et en prévoyant leur situation dans une échancrure limitée par les extensions verticales latérales de ladite base de coque, il est possible de les réaliser simultanément avec le moulage de la base de coque. On évite ainsi des opérations de montage qui grèvent les coûts de fabrication. Avantageusement, les languettes obtenues dans le prolongement des rabats sont prévues d'une certaine largeur permettant de les faire chevaucher les bords de l'échancrure en forme de U formée dans la partie antérieure des extensions verticales de la base de coque.Finally, by directly obtaining the tongues in the extension of the flaps which extend over the top of the shell base and by providing for their location in a notch limited by the lateral vertical extensions of said shell base, it is possible to produce them. simultaneously with the molding of the shell base. This avoids assembly operations which increase the manufacturing costs. Advantageously, the tongues obtained in the extension of the flaps are provided with a certain width allowing them to overlap the edges of the U-shaped notch formed in the front part of the vertical extensions of the shell base.

L'invention sera du reste mieux comprise en se reportant à la description qui suit, en référence aux dessins schématiques annexés montrant, à titre d'exemple, un mode de réalisation de la chaussure de sport.The invention will moreover be better understood by referring to the description which follows, with reference to the appended schematic drawings showing, by way of example, an embodiment of the sports shoe.

La figure 1 est une vue en perspective de la base de coque d'une chaussure de sport selon l'invention avec, au choix, une tige du type à "entrée par l'arrière" ou une tige-collier du type à "entrée par l'avant".FIG. 1 is a perspective view of the shell base of a sports shoe according to the invention with, as desired, a rod of the "rear entry" type or a collar-rod of the "entry" type from the front ".

La figure 3 illustre, vue en perspective de 3/4 avant, la base de coque de la chaussure de la figure 1 avec ses languettes en recouvrement de l'échancrure obtenue sur sa partie antérieure.Figure 3 illustrates, in perspective view of 3/4 before, the shell base of the shoe of Figure 1 with its tongues covering the notch obtained on its front part.

La chaussure de sport représentée à la figure 1 comporte une base de coque 1 et, au choix, une tige 4 du type à "entrée par l'arrière" constituée d'une manchette 2 et d'un capot arrière 3 de fermeture dotés d'un dispositif de serrage 7, ou une tige-collier 5 du type à "entrée par l'avant" présentant des rabats transversaux 6, 6', de fermeture auxquels sont associés des dispositifs de serrage 8. Les tiges 4 ou 5 sont reliées à la base de coque 1 de manière pivotante à l'aide de moyens d'assemblage 9, tels que des rivets coopérant avec des trous correspondants 10 réalisés sur lesdites tiges 4 ou 5 et sur ladite base de coque 1, sur les flancs de ces parties constitutives de la chaussure. La base de coque 1, illustrée sur les figures 1 à 3, est pourvue d'extensions verticales latérales 12 et antérieures 14 et 16 qui prolongent ses parois dans la zone 23 correspondant à la cheville du porteur (non représentée), et qui sont destinées à être recouvertes au moins partiellement par la tige 4 ou 5. Par ailleurs, la base de coque 1 comporte sur le dessus une ouverture longitudinale 17 refermée par une paire de rabats transversaux 13, 15, se chevauchant. Ces rabats 13, 15, sont munis de dispositifs de serrage 18 aptes à les rapprocher entre eux pour assurer la tenue du pied du porteur dans la base de coque 1 par réduction du volume de celle-ci. Par ces différentes dispositions, la tige 4 ou 5 peut être serrée sur le bas de jambe du porteur (non représenté) à l'aide des dispositifs de serrage 7 ou 8 indépendamment du serrage du pied effectué sur la base de coque 1 avec les dispositifs de serrage 18, et tout en préservant une certaine étanchéité entre lesdites base de coque 1 et tige 4 ou 5, grâce aux extensions verticales 12, 14, 16. Selon une caractéristique particulière, les extensions verticales antérieures 14 et 16 sont issues des rabats transversaux 13 et 15 de la base de coque 1, et sont séparées des extensions verticales latérales 12 par des fentes 19 débouchantes vers le haut et orientées sensiblement parallèlement à l'ouverture longitudinale 17 réalisée sur le dessus de la base de coque 1. Les fentes 19 déterminent ainsi les bords 24, 26, d'une échancrure en forme de U dans la partie antérieure des extensions verticales 12 de la base de coque 1, et les extensions verticales antérieures 14 et 16 constituent des languettes. Ces languettes 14, 16, se trouvent de la sorte naturellement en chevauchement partiel puisqu'elles sont dans le prolongement des parties étroites 13', 15', des rabats 13, 15, qui se recouvrent. De préférence, les fentes 19 s'étendent du haut vers le bas approximativement jusqu'à la zone 20 en correspondance du pli de flexion afin d'assurer un enveloppement optimum de la partie du pied situé en vis à vis lors de la mise en oeuvre du dispositif de serrage 18 situé dans cette même zone 20, et afin de faciliter le passage du pied lors du chaussage-déchaussage, surtout s'il s'agit d'une chaussure du type à tige-collier à "entrée par l'avant". En effet, dans ce cas de chaussure, il n'est plus nécessaire d'écarter largement les rabats transversaux 13, 15, car le simple basculement vers l'avant de leurs languettes 14, 16, dégage la zone 20 du pli de flexion et l'échancrure en forme de U où passe la proéminence du cou-de-pied du porteur.The sports shoe shown in FIG. 1 comprises a shell base 1 and, as desired, a rod 4 of the "rear entry" type consisting of a cuff 2 and a rear closing cover 3 provided with 'a clamping device 7, or a rod-collar 5 of the "front entry" type having transverse flaps 6, 6', closing with which are clamping devices 8. The rods 4 or 5 are connected to the hull base 1 pivotally using assembly means 9, such as rivets cooperating with corresponding holes 10 made on said rods 4 or 5 and on said hull base 1, on the sides of these constituent parts of the shoe. The shell base 1, illustrated in FIGS. 1 to 3, is provided with lateral vertical extensions 12 and anterior 14 and 16 which extend its walls in the zone 23 corresponding to the ankle of the wearer (not shown), and which are intended to be covered at least partially by the rod 4 or 5. Furthermore, the shell base 1 has on top a longitudinal opening 17 closed by a pair of transverse flaps 13, 15, overlapping. These flaps 13, 15 are provided with clamping devices 18 able to bring them together to ensure the holding of the wearer's foot in the shell base 1 by reducing the volume thereof. By these different arrangements, the rod 4 or 5 can be clamped on the lower leg of the wearer (not shown) using the clamping devices 7 or 8 independently of the clamping of the foot carried out on the shell base 1 with the devices clamping 18, and while preserving a certain tightness between said shell base 1 and rod 4 or 5, thanks to the vertical extensions 12, 14, 16. According to a particular characteristic, the anterior vertical extensions 14 and 16 come from the transverse flaps 13 and 15 of the shell base 1, and are separated from the lateral vertical extensions 12 by slots 19 opening upwards and oriented substantially parallel to the longitudinal opening 17 made on top of the shell base 1. The slots 19 thus determine the edges 24, 26, of a U-shaped notch in the front part of the vertical extensions 12 of the shell base 1, and the front vertical extensions 14 and 16 are tabs. These tongues 14, 16 are thus naturally in partial overlap since they are in the extension of the narrow parts 13 ', 15', of the flaps 13, 15, which overlap. Preferably, the slits 19 extend from the top down approximately to the zone 20 in correspondence with the bending fold in order to ensure optimum wrapping of the part of the foot located opposite during implementation. of the tightening device 18 located in this same zone 20, and in order to facilitate the passage of the foot during the putting on and taking off, especially if it is a shoe of the type with stem-collar with "entry from the front ". Indeed, in this shoe case, it is no longer necessary to widely spread the transverse flaps 13, 15, because the simple tilting forward of their tongues 14, 16, clears the area 20 of the bending fold and the U-shaped notch where the prominence of the wearer's instep passes.

Avantageusement, les languettes 14, 16, sont prévues d'une certaine largeur permettant de les faire chevaucher les bords 24, 26, de l'échancrure en forme de U, ce qui améliore l'étanchéité latérale et évite les risques de butée "bord à bord" entre les languettes et l'échancrure lorsque la fermeture de la tige 4 ou 5 sur le bas de jambe du porteur tend à resserrer les extensions verticales latérales 12.Advantageously, the tongues 14, 16 are provided with a certain width allowing them to overlap the edges 24, 26 of the U-shaped notch, which improves the lateral tightness and avoids the risks of abutment "edge on board "between the tabs and the notch when the closure of the rod 4 or 5 on the lower leg of the wearer tends to tighten the lateral vertical extensions 12.

Il est bien entendu que tout moyen d'étanchéité peut être interposé entre les rabats transversaux 13, 15, les languettes 14, 16, et/ou entre les languettes 14, 16, et les bords 24, 26, de l'échancrure. Par exemple, des lèvres d'étanchéité flexibles peuvent être employées, qu'elles soient rapportées ou obtenues de moulage d'une pièce avec l'une ou l'autre des parties entre lesquelles elles s'interposent, soit les rabats, les languettes ou les extensions verticales latérales 12.It is understood that any sealing means can be interposed between the transverse flaps 13, 15, the tongues 14, 16, and / or between the tongues 14, 16, and the edges 24, 26, of the notch. For example, flexible sealing lips can be used, whether they are attached or obtained by molding in one piece with one or other of the parts between which they are interposed, either the flaps, the tabs or lateral vertical extensions 12.
