Definitions

• the invention relates to a ventilated shoe, in particular for sports and with a sole with a ventilated cavity.
• FIG. 1 shows a plan view from the top of a first embodiment of the shoe
• FIG. 2a shows a vertical section of the shoe of FIG. 1
• - fig. 2b is a variant of FIG.
• FIG. 1 shows a top view of a sole of another embodiment
• Figure 4 shows a longitudinal section of a ventilated shoe.
• the upper wall 3 is double and has an inner upper wall 4 and an outer upper wall 5 separated by intermediate bands 6 .
• the internal upper wall 4 is intended to enclose the foot and has numerous openings; it has the structure of a flexible net or sieve that is foldable in its transverse direction and relatively rigid in the direction of elongation, so that it can hold the foot if it is tightened on it, while leaving pass air very easily over its entire surface.
• the outer top wall 5 is made of the usual material for this use, that is to say that it resists the passage of water, but allows a certain passage of air, for example leather or fabric in artificial fibers.
• the channels 7 preferably terminate in the transition zone between the sole 2 and the upper wall 3 and have an opening 8 there, at the place where the strips 6 terminate and which is located slightly above the sole. 2 (fig. 2a).
• a variant in fig. 2b represents an opening 8 'directed towards the inside of the shoe, the strips 7 going to the sole and the lowest part of the internal upper wall 4 having this opening 8' facing the air duct.
• the bands 6 towards the instep are arranged in an arch.
• clamping means 9 acting at least on the upper internal wall 4 are provided at the front end of the opening of the shoe; these means 9 can be laces.
• the air intended to pass through the conduits 7 can penetrate by the external upper wall 5 (fig. 2a) and / or by orifices easy to imagine on the surface or at the upper edge of the wall 5.
• the external upper wall 5 fig. 2a
• orifices easy to imagine on the surface or at the upper edge of the wall 5.
• the entire upper wall 3 is provided with strips 6 and therefore that it is entirely dou ⁇ ble. Without departing from the scope of the invention, only part of the wall 3 can be made in duplicate, for example by excluding the wall around the heel and by making the front part of the wall 3 in double walls 4.5.
• the upper surface of the sole 2 has a grooved structure allowing the passage of air.
• this surface has studs designated by the reference 11 in FIG. 1; the air can circulate between the studs 11, which can be slightly elastic.
• the upper surface of the sole carries grooves 11 '. It can be seen that the air passages leave in the two variants of the transition zone between the upper surface of the sole and the upper wall, zone in which the ducts 7 bring fresh air as we have seen previously.
• a thin insole 15 pierced with numerous holes can be placed on the grooved structure (fig. 2b).
• This sole can be similar to the inner wall 4.
• This type of shoe with ventilation around the foot is particularly suitable when used in combination with an elastic sole with cavity integrated in the shoe.
• the cavity 13 which occupies at least part of the elastic sole.
• the cavity 13 is crushed under the weight of the walker and is rebuilt when the shoe is lifted off the ground.
• At least one opening 12 provides the connection between the air passages of the grooved structure 11, 11 ′ of the upper surface of the sole with the interior of the cavity 13.
• these openings 12 carry unidirectional valves 14 (fig. 1, 2a, 2b) which allow air only to enter the cavity 13.
• the cavity 13 is surrounded by an airtight wall.
• the sole is made so that when a part of the sole is compressed by a part of the foot, the upper and lower walls of the cavity approach on this compressed part and the volume of air of this part of the cavity has practically faded away.
• the cavity 13 returns to its initial shape and includes a certain volume of air.
• This elasticity of the shape of the sole with respect to compression is obtained by virtue of an adequate shape and elasticity of the walls of the sole, in particular of the lateral walls of the sole.
• the cavity 13 in the sole 2 is connected to the external atmosphere of a part by one or more openings 14 in the upper front wall of the sole.
• These front openings 14 are made so as to function as unidirec ⁇ tional valves allowing only the entry of air and closing again at the slightest suppression of the air in the cavity relative to the atmosphere.
• the cavity 13 is connected to the external atmosphere by one or more openings 16 formed in the rear side wall of the sole.
• the rear openings are made to function as one-way valves allowing only the air outlet and closing at the slightest depression of the air in the cavity relative to the atmosphere.
• the sole 2 takes the form shown in Figure 4 when the foot lifts off the ground and the shoe is not subjected to any pressure.
• the air inlet openings 12 with the one-way valves 14 are placed in the central part or slightly in front of the central part.
• the air inlet openings can be located at the rear of the sole, or at the rear and in the middle of the sole, or else distributed over the entire upper wall of the sole.
• one or more outlet openings always placed in the side wall of the sole can be located at the front, or at the having and in the middle or even distributed over the periphery of the sole.
• the different locations of the inlet openings can be freely combined with the different locations of the outlet openings.
