Definitions

  • 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.
  • 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 restraint of some of these parts.
  • the footwear due to its characteristics, can also be used as a comfort element in sports shoes and other footwear in common use.
  • the inflatable part can be limited to the sole, to the upper or to a part of it, 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.
  • the chamber or chambers constituting the inflatable part are produced by attached waterproof pockets, networks of tubes or cavities formed in particular in the sole and the various chambers are in communication with each other when the article is actually inflatable but they can be insulated in the case of a "pneumatic" sole.
  • 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 true orthopedic article.
  • the process for producing an article of footwear inflated to different pressures in its different zones is characterized in that a blank is used consisting of a set of cavities intercommunicating by passages of reduced section which can be closed off and connected to at least one fitting. inflation, in that the blank is inflated to the desired pressure for the cavity furthest from the connector and isolates the latter by closing the passages ensuring its communication with the other cavities of the article raising and repeating the operation by changing the pressure until all the cavities are inflated to the desired pressures and isolated.
  • the draft footwear for the implementation of the method according to the invention has on its surface intercommunicating cavities in communication with at least one inflation fitting and is characterized in that at least some of the cavities can be isolated after inflation.
  • certain parts corresponding to certain cavities must provide a compression which may be variable over time, for example during the course of the mal-position, or which may 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).
  • the whole of the inflatable pocket subdivided into the different cavities is secured with at least one skin or layer of similar lining ensuring shape stability and preferably with two such lining layers arranged on its two faces.
  • the different cavities are preformed in their deformation by junction elements joining the two walls of the cavity so as to avoid balloon inflation.
  • junction elements joining the two walls of the cavity so as to avoid balloon inflation.
  • one of the walls of the cavity can be preformed, for example applied by vacuum to a welding electrode or otherwise, before the junction elements are produced.
  • the two walls of the inflatable bag are made of a heat-sealable material, the subdivision into the different cavities and the joining elements being produced by heat-sealings.
  • the two walls are made of polyurethane sheets and the heat seals are made by high frequency welding.
  • 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.
  • 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.
  • the surface of the sole 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 especially the parts constituting the chevil- the era which are subdivided into vertical tubular chambers and sub-divided capital in longitudinal chambers bar.
  • references 1 and 2 denote the polyurethane sheets constituting the upper wall and the lower wall of the inflatable bag; 3 denotes the textile lining applied to the upper wall and 4 the skin applied to the lower wall.
  • the forming heat seals are designated by 5 and the various passages by the reference 6 assigned a letter and possibly an exponent when they are intended to be closed.
  • Reference 7 designates an orifice or window in the skin 4 for the passage of the welding electrodes.
  • the reference 8 designates the assembly bands of the ankle part behind the Achilles tendon, the reference 9 the closure bands, for example covered with adhering fabric of the type sold under the brand "Velcro", of the front part of the ankle and 10 the malleoli release windows.
  • Reference 11 designates the inflation fitting.
  • the boot shown is specific with a straight foot, but it is possible, by assembling polyurethane sheets flat and not preformed and identical leathers on both sides, to produce a blank usable for both feet.
  • the surface of the blank is divided into various zones respectively the ante-capital bar 12, the sub-capital bar 13, the retro-capital bar 14, the internal 15 and external 16 sub-cuboid supports, the internal sub-scaphoid supports 17 and external 18, the heel wedge 19, the anterior portions 20 of the ankle and the posterior portions 21.
  • the posterior portions 21 of the ankle are in communication through a channel 23 bypassing the heel.
  • the sub-capital 13 and retro-capital 15 bars and the parts of the ankle are subdivided by bridging heat seals 5a and the polyurethane sheet 2 is thermoformed in the parts forming the ankle to give larger tubular cavities 22 section under moderate inflation pressure. The thicknesses are exaggerated in Figure 2.
  • the sub-capital part 13 is in communication with the cavity of the ante-capital bar 12 by passages 6a and the sub-capital part can be subdivided by welding passages 6b.
  • the retro-capital part 14 communicates with the ante-capital bar by closable passages 6c.
  • the anterior-capital bar communicates with the sub-cuboid and sub-scaphoid supports by closable passages 6d; the internal and external supports, sub-cuboid and sub-scaphoid, are in communication by closable passages 6e.
  • the sub-cuboid and sub-scaphoid supports 16 and 18 communicate with the heel wedge 19 by closable passages 6f and with the parts of the anterior ankles 20 by passages 6g.
  • the heel wedge communicates with the posterior ankle parts by 6h passages and the anterior and posterior ankle parts communicate together by 6i passages.
  • One of the parts of posterior ankle is in communication with the inflation valve 11.
  • Figure 3 illustrates the use of the slipper for the treatment of flat foot with ankle instability characterized more particularly by ligament instability of the ankle, heel instability, subsidence under the scaphoid and a flat forefoot.
  • One of the passages 6d 'between the sub Cuboid and the ante-capital bar is closed by high frequency welding, the passage 6e' between the internal and external scaphoid subs, the passage 6f 'between the heel wedge and the cuboidiens and one inflates very moderately after which one closes the two passages 6i 'and the passage 6g' between the part of anterior ankle and the under scaphoidien and one inflates with a normal pressure the bars ané, under and retro-capitals, the support under scaphoid external, the wedge heel and the posterior parts of the ankle.
  • Figure 4 corresponds to a hollow foot with instability of the ankle and claw toes.
  • the under and retro-capitals bars are isolated by welding the passages 6a 'and 6c', the internal cuboid support by welding the passage 6e ', after which the ante-capital bars 12 is inflated to normal pressure.
  • Figure 5 concerns the treatment of a typically feminine hollow foot.
  • the sub-capital bar 13 is isolated by welding the two passages 6a ', after having inflated it to normal pressure. The pressure is then reduced and the ante-capital bar 12, the front part of the retro-capital bar 14, the supports under scaphoid 17-18, the support under internal cuboid 15 and possibly the anterior ankle parts 20 are welded.
  • the sub cuboid and the retro-capital bar can be isolated by welding the passage 6f "to avoid the transmission of air between the two bearings.
  • Figure 6 corresponds to the indication of an arcuate anterior-internal hollow foot with hammer toes, requiring an ankle, a wedge heel, support under the cuboid and an ante-capital bar.
  • the bars under the capital and retro capital are isolated by welding the passages 6a 'and 6c', the passage 6d 'between the anterior capital bar 12 and the supports under scaphoid 17-18 is closed, the passage 6f' between the sub scaphoid and the heel wedge, the passages 6i 'and the passage 6g' between the sub Cuboldians and the anterior part of the ankle, after which the intercommunicating cavities are inflated.
  • welds 6 0 'substituted for welds 6c' it is possible, by welds 6 0 'substituted for welds 6c', to pressurize the rear strip of the retro-capital part and also to isolate after inflation the different zones by closing the passages 6d ', 6h', etc. .
  • Figure 7 illustrates the treatment of a flat foot with spread out forefoot.
  • Figure 8 illustrates the treatment of a hollow foot with convex forefoot.
  • a lateral part of the sub-capital bar is isolated by closing the passage 6b 'and a lateral passage 6a'.
  • a moderate pressure is then established and closes the passages 6f ', 6i', 6d ', 6 0 ', 6p ', 6g' and 6e 'indicated to isolate at this pressure the rear band of the retro-capital bar the internal scaphoid 17, the sub cuboidians 15-16 and the anterior parts of the ankle, after which the pressure is inflated to normal pressure and, if necessary, the various inflated pads are isolated.
