Definitions

  • the present invention relates to a ventilation device internal for city or sport footwear allowing in particular the ventilation of the interior of the shoe as well as the evacuation of sweat.
  • Patent FR-B-2,472,354 proposed to limit this discomfort by offering an article of footwear comprising compressible and deformable pneumatic chambers in the sole in communication with pneumatic chambers fitting the rear part of the foot.
  • this guy significantly reduces the discomfort associated with warming up by creating flexibility the article of footwear, it does not solve the problem related to the sweating itself. It is therefore advisable to propose a means to reduce both the inconvenience associated with this warming but also those related to sweating, providing ventilation or air circulation to inside the footwear.
  • Document FR-A-1.019.374 proposes a boot provided with a pocket which extends along the rod and is interposed between the insole and the sole.
  • the pocket In the top of the rod, the pocket is provided with an inlet orifice air and at the end of the pocket under the arch, it has one or more perforations towards the inside of the boot through which air is evacuated when walking.
  • air can be sent either towards the arch or turned upwards the stem. The air circulation is therefore random and by therefore not very effective.
  • Document US-A-2,741,038 proposes the same principle but by introducing valves in the pocket to circulate air in one direction. A such an embodiment offers very limited walking comfort.
  • GB-A-2,189,679 describes a sole molded so as to constitute a pump, the air circulating in one direction according to the principle of compression / depression linked to the movement of works thanks to valves provided in this sole.
  • the making such a sole is difficult to implement work and we risk seeing the upper part crash of the sole inside the recess made in the sole after a certain time of use.
  • EP-A-0,319,968 describes, as for a sole with an internal recess opened by an air intake opening in the heel and provided with perforations under the arch. When installing the heel, the air intake opening is closed by compression and the air is evacuated towards the perforations and there towards the inside of the footwear.
  • Such a sole has the disadvantage of risking sagging from the upper part of the sole in the recess at in use over time.
  • Document FR-A-2,695,303 proposes a device for integrated air circulation at the heel of a sole, consisting of a chamber with an upper wall compressible, a non-return air intake valve heel level and air exhaust channel leading towards the front of the sole. Despite the valve non-return, when the compression is released under the arch, nothing prevents the exhaust air from returning to said compressible chamber via the drainage channel and thus preventing circulation effective air from the heel to the arch of the foot.
  • WO-A-93/07774 proposes a sole which has an orifice air intake at the arch of the foot, the air then being introduced, via a valve non-return in a cavity in the heel and escaping to the outside via a non-return valve by a conduit extending along the shoe upper.
  • a sole which has an orifice air intake at the arch of the foot, the air then being introduced, via a valve non-return in a cavity in the heel and escaping to the outside via a non-return valve by a conduit extending along the shoe upper.
  • EP-A-0 624 322 discloses a ventilated footwear in which a pump is housed in a recess in the portion of the heel of a outsole.
  • the device ventilation also includes a first non-return valve housed in a duct leading out of the outsole and a second non-return valve housed in a duct in connection with air circulation channels in communication with the inside of the footwear in its front part.
  • the pump is connected to these two valves via a conduit opening into a joint into which the other two conduits open, this gasket being housed in the middle part of the sole of wear.
  • WO-A-8910073 there is known a ventilation device in which the compressible chamber is part of the sole in that it is defined between a lower part of the outsole and an upper part of it, the variable volume being defined by callbacks elastic.
  • This compressible chamber is connected to a conduit leading outward and to conduits to inside the article, these conduits being provided respectively of a valve. So when you press exerted on the heel of the sole, it repels air contained in the chamber towards the inside of the article fitting through the valve which is open, the valve in communication with the outside being closed then during release of pressure, the valve in communication with the outside lets in air which is sucked in towards the compressible chamber while the valve in communication with the inside of the footwear closed. In this article of footwear, there is ventilation of the foot but it there is no evacuation of air and sweat from the inside outward of the footwear.
  • FR-A-2 588 044 there is an article of footwear in which the compressible chamber is defined by a housing formed in the heel portion of the outsole, the upper portion of the outsole surmounting said housing being arranged projecting towards the inside of the article of footwear and kept projecting by an element elastic return such as a spring.
  • This room compressible is connected inside the article footwear by a conduit provided with a first non-return valve and outside the footwear by a second duct provided with a second non-return valve.
  • the second non-return valve When pressure exerted on the heel, the second non-return valve is closed and the air is expelled, through the first non-return valve, towards the inside of the article footwear while, when the pressure is released, the first non-return valve is closed and the second valve non-return allows air to pass from outside into the compressible chamber.
  • the present invention provides a ventilation device independent of the footwear consisting of a sole or outsole and a rod, which allows a one-way air flow from the heel of the item fitting to the front part of it and which is of a easy and economical production and assembly.
  • the ventilation device which includes a compressible chamber made of flexible and waterproof material consisting of a tank fitted with a cover, and non-return valves, is characterized in that said cover has membranes forming check valves allowing the entry and evacuation of air in the tank according to a single direction of circulation, and a insole on which said compressible chamber is recessed, said insole comprising on one side a network of air circulation channels in communication with the compressible chamber and being provided perforations communicating said channels with the opposite side of the insole.
  • the cover has on its inner face a diametrically opposite recess and orifice and on its outer face a recess in which the orifice ends of the interior face and an orifice which ends in the recess on the outside, the membranes forming non-return valve being placed in said recesses in order to promote a single possible direction of circulation of the air.
  • this device is introduced into a footwear whose outsole has a cavity capable of accommodating the compressible chamber.
  • said compressible chamber advantageously has dimensions such as that it should protrude slightly above the face upper of the outsole. Said room compressible being embedded in the insole, it is therefore also slightly raised above the heel area of the sole wear and therefore does not rest completely on the outsole.
  • the compressible chamber undergoes deformation of the walls of its reservoir under the effect of the compression exerted by the foot on the insole which comes to rest fully on the upper side of the outsole while an abrasion-resistant disc, placed under the outsole heel slightly protrudes from the surface of this heel in contact with the ground, contributes to the same instant in the compression of the chamber in its part lower.
  • Compressed air then tends to escape from the chamber compressible and exerts pressure on the membranes forming a valve of which at least one is movable and allows air evacuation.
  • the outside of the compressible chamber cover advantageously has recesses on its edges which connect the inlet and outlet ports of the air in the compressible chamber with the network of piping on one side of the sole interior.
  • the air expelled from the compressible chamber is evacuated to the front of the insole through the channels of circulation then, during compression of the front part of the outsole and the insole, the air is evacuated towards the interior front part of the article footwear.
  • the air cannot return to the compressible chamber and is therefore expelled entirely towards the inside of the footwear.
  • the invention also relates to an article of footwear. consisting of a outsole to which is fixed a rod by any means known per se, said outsole having on its upper face, at the heel, an open cavity suitable for accommodating a ventilation device consisting of a chamber compressible in flexible and waterproof material made of tank fitted with a cover comprising membranes forming check valves and embedded in a insole comprising, on its face facing the outsole, a network of pipes in communication with the compressible chamber and provided with perforations leading to the opposite surface of the sole interior.
  • a ventilation device consisting of a chamber compressible in flexible and waterproof material made of tank fitted with a cover comprising membranes forming check valves and embedded in a insole comprising, on its face facing the outsole, a network of pipes in communication with the compressible chamber and provided with perforations leading to the opposite surface of the sole interior.
  • the invention also relates to a method for manufacturing such footwear comprising this device ventilation.
  • a compressible chamber 1 of the device according to the invention preferably of oval cross section, has a tank 2 to which a cover 3 fits and which has a 2 'tab, horizontal or oblique (see Figure 9), at one of its ends.
  • This cover 3 comprises a groove 4 at its periphery in which the upper rim 5 of the tank 2 of the chamber compressible 1 so as to obtain a tight closure.
  • the cover 3 On its outer face E, the cover 3 has a recess 6 and an orifice 7 preferably located diametrically opposed. On its inner face I, the cover 3 has a recess 8 in which ends the orifice 7 while it has an orifice 9 diametrically opposite to the recess 8 and which ends in the recess 6.
  • the recesses 6 and 8 are made so as to accommodate respectively membranes forming valve 10 and 11 which admit respectively only one direction of circulation of the air.
  • the orifices 7 and 9 ending in the recesses 6 and 8 are closed by the membranes forming a valve 10 and 11.
  • the air can be evacuated from compressible chamber 1 only through valve 10 which can be moved under the effect of a air push due to compression of the chamber compressible 1.
  • valve 10 which can be moved under the effect of a air push due to compression of the chamber compressible 1.
  • air is admissible in said chamber only through the valve 11 moved by the air entering the tank 2 when the pressure is released. So we have a unique sense of entry and air outlet in room 1.
  • the cover 3 also has recesses 12 and 13 on its outer face.
  • the recess 12 is located between the edge of the cover 3 and the orifice 7 while that the recess 13 extends from the recess 6 towards the edge of the cover 3.
  • These recesses 12, 13 provide passageways for air when the compressible chamber 1 is fitted on the insole 14.
  • the sole 14 has on its underside, facing the outsole when fitting into an article footwear, a network of pipes 15 which allow the air coming from the compressible chamber 1 of circulate under the insole 14. In places, said sole 14 has perforations 16 which allow air to escape to the interior of the article of footwear through said sole 14.
  • the rear of the sole 14 has a cavity 17 in which the compressible chamber 1 is built-in.
  • the ventilation device according to the invention consisting by the compressible chamber 1 and the insole 14, is introduced into an article of footwear 19 consisting of a outsole 20 on which is fixed by all means known per se a rod 21.
  • the outsole 20 has on its upper face a cavity 22 in which the compressible chamber 1 is housed.
  • the dimensions of the compressible chamber 1 are such that the sole 14 on which it is embedded is not fully supported on the outsole 20.
  • a tablet 23 of a material having a high resistance to abrasion is arranged on the underside of the outsole 20, at the level of the heel and opposite cavity 22, slightly protruding by compared to the surface of the sole 20. This increases the heel impact force when walking which allows to exert compression on the lower part of the compressible chamber 1.
  • the air contained in said compressible chamber 1 escapes, under the pressure thus exerted, by the valve 10 towards the network of pipes 15 of the insole 14.
  • the air escapes to the through perforations 16 towards the inside of the article footwear.
  • the pressure being released on the heel the walls of the compressible chamber 1 are put back in place and room 1 admits, again a air inlet via the valve 11, the air then being collected at the heel in the footwear.
  • the tongue 2 ′ made of flexible material, present at the end of the tank 2 of the chamber compressible 1 can be made so as to be oblique so that when the compressible chamber is introduced in the cavity 22 of the outsole 20, the end of said tongue 2 ′ rests on the outsole 20 as shown in Figure 9.
  • valves 10 and 11 operating only one way to admit or exhaust air from the compressible chamber 1.
  • the invention also relates to a manufacturing method using a mounting form of the type shown in Figure 10a and which includes a protrusion under the heel to create a sole wear 20 having a cavity 22.
  • This shape is preferably used for mounting the so-called "slip" type, the first mounting presenting pre-cut slots to allow passage of the outgrowth of the form as is visible from the Figure 10b.
  • the outsole 20 obtained has the cavity 22 into which the compressible chamber 1.
