Description

On a déjà proposé, par exemple dans les brevets français N° 317.846 et 341.490, de réaliser des chaussures dont la semelle comporte une ou des chambres à air qui peuvent être gonflées au moyen d'une valve. Ces semelles ont essentiellement pour but d'amortir, par un effet pneumatique, le choc du talon contre le sol au cours de la marche ou de la course. Un problème se pose toutefois en ce qui concerne le volume desdites chambres et leur déformabilité qui doit être limitée pour conserver une stabilité suffisante à l'appui du pied. Ceci signifie que, pour que la chambre pneumatique joue son rôle d'absorbeur d'énergie, la pression de l'air à l'intérieur de la chambre doit être élevée et elle croit très rapidement pour une faible déformation de la chambre alors que le confort exigerait que l'énergie soit absorbée par une déformation plus importante avec une pression quasi- constante.It has already been proposed, for example in French patents No. 317,846 and 341,490, to produce shoes whose sole has one or more air chambers which can be inflated by means of a valve. The purpose of these soles is essentially to absorb, by a pneumatic effect, the impact of the heel against the ground during walking or running. However, a problem arises with regard to the volume of said chambers and their deformability which must be limited in order to maintain sufficient stability in support of the foot. This means that, for the pneumatic chamber to play its role of energy absorber, the air pressure inside the chamber must be high and it increases very quickly for a small deformation of the chamber while the comfort would require that the energy be absorbed by a greater deformation with an almost constant pressure.

On a aussi proposé dans le brevet français N° 1.406.610 de munir les parois internes des chaussures de ski d'une ou plusieurs chambres gonflables. Le but de ces chambres gonflables est d'obtenir un serrage du pied avec une répartition uniforme de la pression entre le pied et la chaussure. De telles chambres sont essentiellement utiles dans des chaussures à tiges hautes dans lesquelles le serrage des lacets pour maintenir fermement la cheville est important afin d'éviter tout risque d'accidents à ce niveau.It has also been proposed in French Patent No. 1,406,610 to provide the internal walls of ski boots with one or more inflatable chambers. The purpose of these inflatable chambers is to obtain a tightening of the foot with a uniform distribution of the pressure between the foot and the shoe. Such chambers are essentially useful in shoes with high uppers in which the tightening of the laces to firmly maintain the ankle is important in order to avoid any risk of accidents at this level.

On a également proposé, pour assurer un bon emboîtement du calcanéum, de prévoir une bande élastique entourant la cheville et passant derrière le tendon d'Achille. L'élasticité de la partie arrière de la tige ainsi réalisée a pour but de permettre de chausser la chaussure tout en évitant un baillement de cette partie lors de la flexion de la cheville. Toutefois cette pression permanente peut s'avérer génante à l'usage et elle croit au moment de l'extension du pied.It has also been proposed, to ensure good interlocking of the calcaneus, to provide an elastic band surrounding the ankle and passing behind the Achilles tendon. The elasticity of the rear part of the upper thus produced is intended to allow the shoe to be put on while avoiding a yawning of this part when the ankle bends. However, this permanent pressure can be annoying when used and increases when the foot is extended.

Il a enfin et depuis de longues années été d'usage courant de découper en croissant la partie supérieure arrière de la tige au-dessus du calcanéum et de la.remplacer par une pièce rapportée en un matériau plus souple destinée à éviter les blessures du tendon d'Achille.Finally, it has been in common practice for many years to cut the upper rear part of the rod growing above the calcaneus and replace it with an insert made of a more flexible material intended to avoid injury to the tendon. Achilles.

Des études approfondies ont montré que tous ces moyens présentaient des insuffisances ou des inconvénients et que notamment il était souhaitable d'arriver à combiner leurs principes d'action pour aboutir a un bon maintien du pied dans la chaussure. De plus il s'est avéré nécessaire d'as- sùrer un meilleur emboîtement du pied dans la partie arrière de la chaussure au moment de l'écrasement des chambres pneumatiques tout en réduisant la pression exercée sur le tendon d'Achille par la bride élastique ou la partie arrière de la tige pendant la période d'extension du pied. Le problème à résoudre était en quelque sorte d'accroître le volume des chambres pneumatiques d'appui du pied réalisées dans la semelle pour en permettre une plus grande déformation volumique pour une faible variation de la pression unitaire, de faire suivre à la surface d'emboîtement du croissant souple le mouvement du tendon d'Achille pour conserver un appui élastique réparti sur une surface importante au-dessus du calcanéum et qui ne varie que peu en intensité entre les positions de repli ou d'extension de la cheville pour lesquelles le tendon d'Achille s'écarte ou se rapproche respectivement du croissant et d'emboîter latéralement le talon de part et d'autre et sur une hauteur notable, environ jusqu'au droit de la voute plantaire avec une pression accrue au moment de la mise en appui de façon que cet emboîtement sous compression pallie la déformabilité des chambres pneumatiques de la semelle.Extensive studies have shown that all of these means have shortcomings or drawbacks and that in particular it is desirable to be able to combine their principles of action to achieve good foot support in the shoe. In addition, it has been found necessary to ensure a better fitting of the foot in the rear part of the shoe when the pneumatic chambers are crushed while reducing the pressure exerted on the Achilles tendon by the elastic strap. or the rear part of the upper during the extension period of the foot. The problem to be solved was, in a way, to increase the volume of the pneumatic support chambers for the foot made in the sole to allow greater volume deformation for a small variation in unit pressure, to make the surface follow interlocking of the flexible crescent the movement of the Achilles tendon for maintain an elastic support distributed over a large area above the calcaneus and which varies only slightly in intensity between the folded-in or extended ankle positions for which the Achilles tendon deviates or approaches the crescent respectively and to fit the heel laterally on either side and over a significant height, approximately to the right of the arch of the foot with increased pressure at the time of pressing so that this compression fit overcomes the deformability of the pneumatic sole chambers.

Ces résultats sont atteints avec la chaussure conforme à l'invention laquelle comporte une semelle avec des chambres pneumatiques disposées au moins partiellement en dessous de la surface d'appui du talon du pied et une tige munie de chambres à air, cette chaussure étant caractérisée en ce que les chambres à air de la tige déformables au moins vers l'intérieur de la chaussure sont prévues dans les parties emboîtant la partie arrière du pied et sont en communication avec la ou les chambres pneumatiques de la semelle.These results are achieved with the shoe according to the invention which comprises a sole with pneumatic chambers disposed at least partially below the bearing surface of the heel of the foot and a rod provided with air chambers, this shoe being characterized in that the air chambers of the upper deformable at least towards the inside of the shoe are provided in the parts fitting the rear part of the foot and are in communication with the pneumatic chamber or chambers of the sole.

Selon une autre caractéristique, les chambres à air déformables sont réalisées dans les flancs de la tige emboîtant latéralement le talon.According to another characteristic, the deformable air chambers are produced in the sides of the rod laterally fitting the heel.

Selon une caractéristique supplémentaire, les chambres à air déformables de la tige sont formées par un jeu prévu entre au moins une partie des flancs de la tige et sa doublure, tous deux réalisés en un matériau imperméable à l'air.According to an additional characteristic, the deformable air chambers of the rod are formed by a clearance provided between at least part of the sides of the rod and its lining, both made of an air-impermeable material.

Selon une autre caractéristique la pièce constituant le croissant souple de protection du tendon d'Achille comporte également une chambre à air dont au moins la paroi faisant face à l'intérieur de la chaussure est déformable, cette chambre étant également en communication avec la ou les chambres pneumatiques de la semelle.According to another characteristic, the part constituting the flexible crescent of protection of the Achilles tendon also comprises an air chamber of which at least the wall facing the inside of the shoe is deformable, this chamber also being in communication with the pneumatic chamber or chambers of the sole.

De préférence le système des chambres pneumatiques peut être gonflé ou dégonflé au moyen d'une valve de type connu, de préférence une valve du type à bille.Preferably, the system of pneumatic chambers can be inflated or deflated by means of a valve of known type, preferably a valve of the ball type.

La présente invention est applicable principalement aux . chaussures de sport dites basses pour la pratique de la marche, de la course, du tennis, du basket et analogue.The present invention is mainly applicable to. so-called low sports shoes for walking, running, tennis, basketball and the like.

D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture de la description détaillée d'un mode de réalisation faite ci-après avec référence aux dessins ci-annexés dans lesquels :

  • La figure 1 est un schéma avec la tige développée à plat d'une chaussure conforme à l'invention; la figure 2 est une vue en coupe longitudinale de la partie arrière de la chaussure et la figure 3 en est une vue en coupe par III-III de figure 2.
Other characteristics and advantages of the present invention will appear on reading the detailed description of an embodiment given below with reference to the attached drawings in which:
  • Figure 1 is a diagram with the upper developed flat of a shoe according to the invention; FIG. 2 is a view in longitudinal section of the rear part of the shoe and FIG. 3 is a view in section through III-III of FIG. 2.

Dans les dessins la référence 1 désigne la partie avant de la chaussure avec son renfort de bout 2 et ses bandes d'oeillet 3. Dans la figure 1 on a présenté les flancs-4 de la tige 5 en un matériau imperméable à l'air et la partie arrière 6 de la tige à l'état coupé et rabattu dans le plan supérieur de la semelle. La référence 7 désigne la masse de la semelle qui peut être en mousse de polyuréthane.In the drawings, the reference 1 designates the front part of the shoe with its toe reinforcement 2 and its eyelet bands 3. In FIG. 1 the flanks-4 of the upper 5 are presented in an air-impermeable material. and the rear part 6 of the upper in the cut and folded state in the upper plane of the sole. Reference 7 designates the mass of the sole which can be made of polyurethane foam.

Selon le mode de réalisation illustré à titre d'exemple la surface supérieure de la semelle au voisinage du talon présente une cavité 8 de faible profondeur qui se prolonge par un canal 9 remontant dans l'axe du renfort de talon 10. Le long du canal 9 est prévue une soupape à bille 11 de type connu. Dans le mode de réalisation décrit à titre d'exemple et représenté,on suppose que la semelle 7 et le renfort de talon 10 sont moulés et que les bords de la tige 5 sont noyés au moulage selon le procédé de montage connu. La cavité 8 laisse subsister un rebord 12 à l'intérieur par rapport aux flancs 4 de la tige, ces rebords étant interrompus par une encoche 13.According to the embodiment illustrated by way of example, the upper surface of the sole in the vicinity of the heel has a shallow cavity 8 which is extended by a channel 9 rising in the axis of the heel reinforcement 10. Along the channel 9 is provided a ball valve 11 of known type. In the embodiment described by way of example and shown, it is assumed that the sole 7 and the heel reinforcement 10 are molded and that the edges of the rod 5 are embedded in the molding according to the known mounting method. The cavity 8 leaves a rim 12 inside with respect to the sides 4 of the rod, these rims being interrupted by a notch 13.

Une doublure 14 en un matériau imperméable à l'air est alors engagée dans la partie arrière de la chaussure et collée et vulcanisée selon les surfaces 15 hachurées dans la figure 1, ces surfaces correspondant aux surfaces intérieures des flancs 4, du renfort de talon en dehors du canal 16, sur les rebords 12 et sur la semelle en avant de la cavité 8. La doublure 14 est retournée à l'arrière en 17 et collée et vulcanisée sur le bord de la surface extérieure du renfort de talon pour constituer le croissant protecteur du tendon d'Achille.A lining 14 made of an air-impermeable material is then engaged in the rear part of the shoe and glued and vulcanized according to the hatched surfaces 15 in FIG. 1, these surfaces corresponding to the interior surfaces of the sides 4, of the heel reinforcement in outside the channel 16, on the flanges 12 and on the sole in front of the cavity 8. The lining 14 is turned over at the rear at 17 and glued and vulcanized on the edge of the outer surface of the heel reinforcement to form the crescent protector of the Achilles tendon.

Ainsi se trouvent réalisés une chambre 18 sous le talon au droit de la cavité 8, deux chambres 19 sur les flancs 4 et un ballonnet 20 au droit du protecteur du tendon d'Achille. Lors du gonflage sous une pression modérée, ces chambres se déforment vers l'intérieur sans s'opposer cependant à l'introduction du pied, l'engagement entre les chambres 19 et 20 se faisant sans compression exercée sur la chambre 18. Lorsque le pied est engagé il est légèrement comprimé par les ballonnets constitués par les chambres 19 et 20 à l'état gonflé. Si une pression s'exerce au droit de la cavité 8, la réduction de volume de la chambre 18 se traduit par une augmentation de la pression dans les chambres 19 et 20 mais cette variation de pression est beaucoup plus faible qu'elle ne l'aurait été dans la chambre 18 isolée et elle agit dans les chambres 19 et 20 pour mieux bloquer la tige sur le pied.Thus are made a chamber 18 under the heel to the right of the cavity 8, two chambers 19 on the sides 4 and a balloon 20 to the right of the protector of the Achilles tendon. During inflation under moderate pressure, these chambers deform inward without however opposing the introduction of the foot, the engagement between the chambers 19 and 20 being made without compression exerted on the chamber 18. When the foot is engaged it is slightly compressed by the balloons formed by the chambers 19 and 20 in the inflated state. If a pressure is exerted on the right of the cavity 8, the reduction in volume of the chamber 18 results in an increase in the pressure in the chambers 19 and 20 but this variation in pressure is much smaller than it would would have been in chamber 18 isolated and it acts in chambers 19 and 20 to better lock the rod on the foot.

Le mode de réalisation ci-dessus décrit à titre d'exemple est susceptible de recevoir de nombreuses modifications sans sortir du cadre des revendications ci-annexées.The embodiment described above by way of example is capable of receiving numerous modifications without departing from the scope of the appended claims.
