Abstract

1. A method of manufacturing footwear inflated pneumatically at different pressures in its different regions, in which is used a rough shape made of an assembly of cavities (12 to 22) communicating with each other via passages of reduced section (6) and connected to at least one inflating nipple (11), wherein the rough shape is inflated at the required pressure for the cavity which is the most remote from the nipple and said cavity is isolated by closing the passages which set it in communication with the other cavities of the rough shape and the operation is repeated successively for each cavity which is still not inflated and which is the most remote from the inflating nipple by modifying the pressure until all the cavities are inflated to the required pressure and isolated.

Description

La présente invention concerne les articles chaussants, ce terme englobant les semelles rapportées dans les chaussures de tous types, les tiges basses et montantes, associées ou non à une semelle, incorporées dans les mêmes chaussures et les chaussons ou articles chaussants légers qui peuvent être portés seuls ou placés dans d'autres articles chaussants.The present invention relates to footwear, this term encompassing the soles added in shoes of all types, the uppers and uppers, associated or not with a sole, incorporated in the same shoes and the slippers or light footwear which can be worn. alone or placed in other footwear.

La présente invention a plus spécialement pour but de réaliser un article chaussant orthopédique susceptible d'assurer un soutien ou maintien sélectif des différentes parties du pied, éventuellement de la jambe, associé ou non à une contention de certaines de ces parties. L'article chaussant, du fait des ses caractéristiques, peut également être utilisé comme élément de confort dans les chaussures de sport et autres articles chaussants d'usage courant.The present invention more specifically aims to produce an orthopedic footwear capable of providing selective support or maintenance of the different parts of the foot, possibly of the leg, associated or not with a compression of some of these parts. The footwear, because of its characteristics, can also be used as a comfort element in sports shoes and other footwear in common use.

On a déjà proposé des articles chaussants gonflables de conceptions très diverses. Dans ces articles connus la partie gonflable peut être limitée à la semelle, à la tige ou à une partie de celle-ci, notamment à l'emboîtement du tarse, ou entourer une partie importante du pied et même remonter pour emboîter la jambe comme dans les chaussures de ski, comme décrit dans FR-A 2144464.Inflatable footwear of very different designs has already been proposed. In these known articles, the inflatable part can be limited to the sole, to the upper or to a part thereof, in particular to the interlocking of the tarsus, or to surround a large part of the foot and even to go back up to fit the leg as in ski boots, as described in FR-A 2144464.

La ou les chambres constituant la partie gonflable sont réalisées par des poches étanches rapportées éventuellement amovibles comme décrit dans US-A 4083127, des réseaux de tubes ou des cavités ménagées notamment dans la semelle comme décrit dans FR-A 4083127, des réseaux de tubes ou des cavités ménagées notamment dans la semelle comme décrit dans FR-A 2458239 et les différentes chambres sont en communication les unes avec les autres lorsque l'article est réellement gonflable mais elles peuvent être isolées lorsqu'il s'agit d'une semelle «pneumatique».The chamber or chambers constituting the inflatable part are produced by sealed waterproof pockets optionally removable as described in US-A 4083127, networks of tubes or cavities formed in particular in the sole as described in FR-A 4083127, networks of tubes or cavities formed in particular in the sole as described in FR-A 2458239 and the different chambers are in communication with each other when the article is actually inflatable but they can be isolated when it is a "pneumatic" sole "

Les inconvénients des articles chaussans gonflables antérieurs résident dans la pression de gonflage uniforme de toutes les chambres et dans l'instabilité d'une semelle comportant des chambres étendues en intercommunication, l'air étant, pendant l'usage, chassé des parties les plus chargées vers les parties les moins chargées. L'avantage de ces articles est par contre d'assurer un meilleur confort et d'absorber les chocs pendant la marche et la course. En outre ces articles chaussants sont standardisés et ne présentent qu'une possibilité d'adaptation très faible au pied à chausser, savoir une pointure et une pression de gonflage. Enfin ils ne permettent pas de répartir les coussins gonflés en fonction des caractéristiques morphologiques du pied à chausser. Ces inconvénients se retrouvent notamment das FR-A 2 458 239 dans lequel la semelle comporte des chambres à air réparties en chambres communicantes et chambres non communicantes. Il est proposé dans ce brevet de gonfler les chambres non communicantes à des pression différentes mais aucun moyen pratiques n'est décrit pour gonfler les différentes chambres à des pressions différentes.The disadvantages of previous inflatable footwear reside in the uniform inflation pressure of all the chambers and in the instability of a sole comprising extended chambers in intercommunication, the air being, during use, expelled from the most loaded parts. to the less loaded parts. The advantage of these articles, on the other hand, is to provide better comfort and absorb shocks during walking and running. In addition, these footwear is standardized and presents only a very slight possibility of adaptation to the foot, namely a size and an inflation pressure. Finally, they do not allow the inflated cushions to be distributed according to the morphological characteristics of the foot to be fitted. These drawbacks are found in particular in FR-A 2 458 239 in which the sole comprises air chambers distributed in communicating rooms and non-communicating rooms. It is proposed in this patent to inflate the non-communicating chambers to different pressures, but no practical means is described for inflating the different chambers to different pressures.

L'invention a pour but de créer un article chaussant gonflable qui remédie aux inconvénients et insuffisances des articles du même genre antérieurement connus et qui, de par sa constitution, est susceptible de réaliser un véritable article orthopédique.The invention aims to create an inflatable footwear which overcomes the disadvantages and inadequacies of articles of the same kind previously known and which, by its constitution, is capable of producing a real orthopedic article.

Le procédé de réalisation d'un article chaussant gonflé pneumatiquement à des pressions différentes dans ses différentes zones dans lequel on utilise une ébauche constituée par un ensemble de cavités intercommuniquant par des passages de section réduite et reliées à au moins un raccord de gonflage, est caractérisé en ce que l'on gonfle l'ébauche à la pression recherchée pour la cavité la plus éloignée du raccord et isole celle-ci en obturant les passages assurant sa mise en communication avec les autres cavités de l'ébauche et répète l'opération successivement pour chaque cavité non encore gonflée et la plus éloignée du raccord de gonflage en modifiant la pression jusqu'à ce que toutes les cavités soient gonflées aux pressions voulues et isolées.The method for producing an article of footwear inflated pneumatically to different pressures in its different zones in which a blank is used consisting of a set of cavities intercommunicating by passages of reduced section and connected to at least one inflation fitting, is characterized in that the blank is inflated to the desired pressure for the cavity furthest from the fitting and isolates the latter by closing the passages ensuring its communication with the other cavities of the blank and repeating the operation successively for each cavity not yet inflated and furthest from the inflation fitting by modifying the pressure until all the cavities are inflated to the desired pressures and isolated.

L'ébauche d'article chaussant pour la mise en oeuvre du procédé conforme à l'invention présente sur sa surface des cavités intercommuniquant par des passages de section réduite et reliées à au moins un raccord de gonflage et est caractérisée en ce qu'au moins certains des passages de section réduite assurant l'intercommunication entre le raccord de gonflage et certaines des cavités, sont obturables après gonflage pneumatique des cavités.The draft footwear for the implementation of the method according to the invention has on its surface cavities intercommunicating by passages of reduced section and connected to at least one inflation fitting and is characterized in that at least some of the passages of reduced section ensuring intercommunication between the inflation fitting and some of the cavities, can be closed after pneumatic inflation of the cavities.

Dans l'article chaussant gonflé obtenu par le procédé conforme à l'invention, on évite la circulation d'air entre les cavités laquelle est responsable de l'instabilité de la semelle, on peut gonfler plus ou moins certaines cavités pour réaliser des barres de soutien anté-capitale, rétro-capitale ou sous-capitale, des soutiens sous scaphoïdien ou sous cuboïdien, un enclavement talonnier ou une chevillère parfaitement adaptés au pied, et, de ce fait, traiter médicalement des mal-positions, sub-luxations ou luxations, traumatiques ou congénitales, du couple de torsion astragalo-calcanéen résultant d'une insuffisance ligamentaire ou d'une insuffisance musculaire des valgisants et du court péronier latéral.In the inflated footwear obtained by the process according to the invention, air circulation between the cavities is avoided which is responsible for the instability of the sole, it is possible to inflate more or less certain cavities to make bars of ante-capital, retro-capital or sub-capital support, support under the scaphoid or under the cuboid, a wedge heel or ankle brace perfectly suited to the foot, and, therefore, medically treat mal-positions, sub-luxations or dislocations , traumatic or congenital, of the astragalo-calcaneal torsion couple resulting from a ligament insufficiency or a muscular insufficiency of the valgisants and the short lateral peroneal.

Lorsque, dans l'article chaussant gonflé obtenu, certaines parties correspondant à certaines cavités doivent assurer une contention qui peut être variable dans le temps, par exemple au cours de l'évolution de la mal-position, ou qui peut varier parce que l'assemblage de forme de ces parties n'est pas fixe, par exemple l'assemblage des parties constituant une chevillère qui doivent être séparées pour chausser l'article, les cavités de ces parties restent de préférence en communication avec le ou les raccords de gonflage.When, in the inflated footwear obtained, certain parts corresponding to certain cavities must provide a compression which can be variable over time, for example during the evolution of the mal-position, or which can vary because the shape assembly of these parts is not fixed, for example the assembly of the parts constituting an ankle which must be separated to fit the article, the cavities of these parts preferably remain in communication with the inflation fitting (s).

Selon une autre caractéristique de la l'invention, l'ensemble de la poche gonflable subdivisée en les différentes cavités, est solidarisé avec au moins une peausserie ou couche de doublage disposées sur ses deux faces.According to another characteristic of the invention, the assembly of the inflatable pocket subdivided into the different cavities, is secured with at least one skin or lining layer arranged on its two faces.

Selon un mode de réalisation préférentiel, au moins certaines cavités sont préformées dans leur déformation par des éléments de jonction réunissant les deux parois de la cavité concernée de manière à éviter la déformation en ballonet de ladite cavité sous l'effet de la pression de gonflage. L'une des parois de la cavité peut être réalisée en un matériau thermoformable, ladite paroi étant préformée sensiblement à la forme qu'elle doit avoir après gonflage pneumatique dans l'article chaussant terminé.According to a preferred embodiment, at least certain cavities are preformed in their deformation by junction elements joining the two walls of the cavity concerned so as to avoid the balloon deformation of said cavity under the effect of the inflation pressure. One of the walls of the cavity can be made of a thermoformable material, said wall being preformed substantially to the shape which it must have after pneumatic inflation in the finished footwear.

De préférence les deux parois de la poche gonflable sont en un matériau thermosoudable, la subdivision en les différentes cavités et les éléments de jonction étant réalisés par des thermosoudures. En pratique les deux parois sont réalisées par des feuilles de polyuréthane et les thermosoudures sont réalisées par soudage à haute fréquence. Dans ce cas et selon le mode de réalisation préférentiel, les passages de section réduite obturables sont réalisés par des interruptions des thermosoudures de l'ébauche et leur obturation pendant la mise en oeuvre du procédé est assurée par une thermosoudure. De préférence les emplacements des passages obturables de communication entre les cavités sont repérés sur au moins une des couches ou peausseries de doublage, par exemple par des fenêtres d'engagement des électrodes de soudage.Preferably the two walls of the inflatable bag are made of a heat-sealable material, the subdivision into the different cavities and the junction elements being produced by heat-sealings. In practice, the two walls are made of polyurethane sheets and the heat seals are made by high frequency welding. In this case and according to the preferred embodiment, the passages of closable reduced section are produced by interruptions of the heat seals of the blank and their sealing during the implementation of the process is ensured by a heat seal. Preferably, the locations of the closable communication passages between the cavities are identified on at least one of the lining layers or skins, for example by windows for engaging the welding electrodes.

De préférence la surface de la semelle est subdivisée en une zone d'enclavement talonnier, des zones de soutien sous-scaphoïdienne et sous- cuboïdienne, des zones correspondant aux barres rétro-capitale, sous-capitale et anté-capitale et la semelle est associée avec une chevillère. Certaines des zones peuvent elles-même être subdivisées pour que leurs différentes parties puissent être gonflées différemment. Il en est ainsi notamment des parties constituant la chevillère qui sont subdivisées en chambres verticales et de la barre sous-capitale subdivisée en chambres longitudinales.Preferably the sole surface is subdivided into a heel wedge zone, sub-scaphoid and sub-cuboid support zones, zones corresponding to the retro-capital, sub-capital and ante-capital bars and the sole is associated. with an ankle brace. Some of the zones can themselves be subdivided so that their different parts can be inflated differently. This is particularly so of the parts constituting the ankle which are subdivided into vertical chambers and of the sub-capital bar subdivided into longitudinal chambers.
