Description

The present invention relates to a ventilation for a

  shoe, which is adapted to reject the smell that reigns there.

  According to the prior art, the method for rejecting the odor inside a shoe involves providing two or three relatively small ventilation holes, formed in the lower central part of the footprint. However according to such an arrangement, the aeration not being forced, are limited to the part adjacent to the ventilation holes. In addition, since dust, water or other elements on the roadway also enter the shoe through the ventilation holes, these elements produce bad effects more significant than the aeration effect to prevent odors . Such a device according to the prior art actually does more harm than good and it can be concluded that, after all, such a device is more intended for good form than for claiming to have an anti-odor effect. However, the installation of a fan would create difficulties for walking and would not be practical, given its size and weight and the fact that it

  would include a control system.

  The object of the present invention is to provide ventilation for a shoe that will automatically ventilate it, so that its

  interior will stay clean all the time.

  The invention still provides for shoe ventilation which is

  Removable and can be adapted to almost all types of shoes.

  The invention also aims at a shoe ventilation which is mounted inside thereof without increasing its overall size and

his weight.

  Another object of the present invention is shoes that are comfortable to wear and prevent the walker from being fatigued. In accordance with the present invention, there is provided a shoe vent which includes a resilient plastic soleplate that can be removably inserted into the shoe. The sole includes a pump which is integral and is apatie to suck the air in and expel by the pressure and release released by the foot of the walker. The pump is equipped with a chamber, several intake valves to suck air passing through the chamber and several expulsion valves

  to direct the air towards the inner front part of the shoe.

  According to a variant of the invention, the ventilation can be placed in a shoe. With this type of ventilation, a pump can be an integral part of the sole of the shoe or can be

  uontée on the vamp inside the shoe.

  When a person, who wears shoes with such ventilation, walks, his weight presses on each shoe or shoe is deformed. When this occurs, the pump operates in such a way that fresh air sucks from the inlet ports is sent through the expulsion ports to the inner front portion of the shoe, and the air, including the The smell prevailing inside the latter and more particularly in the front part, are expelled by the fresh air from the pump to the outside. Subsequently, when the foot is lifted, the shoe is relieved of weight or deformation and thus fresh air is drawn from the outside of the shoe into the pump. When the weight of the body again presses on the shoe or when it is again deformed, the aeration action described above is renewed preventing the

  the shoe is poorly fitted and thus keeping it clean.

  The annexed drawing, given by way of example, will make it possible to better understand the invention, the characteristics which it presents and the advantages which it is likely to provide. 1 is a perspective view of an insole,

  Fig. 18 and 19 are perspective views of shoe ventilation according to an eighth variant of the invention, in use position.

  Referring now to FIGS. 1 to 5, one can see shoe ventilation performed according to a first variant of the invention. As shown, the ventilation comprises an insole 2 made of elastic plastic and adapted to be placed on a sole 3 of a shoe 1. The insole 2 comprises a pump 4 which forms an integral part thereof and is adapted to suck the air inside and expel according to the pressure and relaxation of the weight of the body of the walker, relative to the sole 3 of the shoe 1 through said sole 2. The pump 4 comprises intake ports 5 made on each side of the heel of the insole 2 and

  expulsion ports 6 which are at the front of said sole 2.

  Inlet valves 7 are disposed in the respective inlets 5 and are designed to be open only when the air is sucked in, while outlet valves 8 are disposed in respective ports 6 and are designed to be open only when the air is expelled. The pump 4 is provided with a chamber 9 which is divided by partitions 10 into a number of small chambers or cells 11 communicating with each other through ventilation holes 12, said partitions 10 giving a sufficient effect of force and damping 35 to the sole 2. The latter also comprises on each side of the heel, two vertical extensions 13 of the same level with intake ports 14, so as to allow the easy introduction of air

in the holes 5.

  The operation of the ventilation mechanism according to the first variant of the invention is described below. When a person, who wears the shoes 1 provided with the ventilation thus designed, walks, the weight of his body presses on the inner sole 2 of said shoe and thus the air which is in the cells 11 of the pump 4 circulates at through the ventilation holes 12, in one direction and is kept under pressure from the expulsion ports 6 inside the shoe 1. As a result, the air and the odor that reign in the latter are expelled by the fresh air of the 10- pump 4. Then, when the foot is raised, the insole 2 is relieved of weight, fresh air outside the latter is sucked in one direction, through the intake ports 14 of the extensions 13, then through the orifices 5 of the pump 4. When the weight again presses on the sole 2, the ventilation action 15. described above is renewed, thus avoiding the shoe to be poorly ventilated and keep it clean all the time. It will be noted that the cells 11 in the chamber 9 produce a cushioning effect, making the shoe particularly comfortable to wear and preventing the walker from being fatigued. Of surcrott, the ventilation being located in the sole 2 separate shoe 1, it can be easily adapted to any type of shoe. In addition, since no opening has to be provided for the ventilation of each side of the lower part of the upper of the boot, there is no fear that the dust, water or other element will penetrate during the action of ventilation inside, the shoe

  therefore always clean.

  Next fig. 6 and 7 showing a second variant of the method according to the invention, a shoe 15 comprises a vamp 16 of sewn material, such as fabric or leather, and a soleplate 17 of molded elastic material, such as rubber or synthetic resin. The shoe 15 comprises at the sole 17, a pump 18 which is an integral part and is intended to suck the air inside and expel by pressure and relaxation of the weight of the body of the The pump 18 is provided with inlet orifices 19 located at the heel of said soleplate and the expulsion orifices 20 located at the front part thereof. Intake valves 21 are respectively disposed in the orifices 19 and are adapted to open only when the air is sucked in, while expulsion valves 22 are respectively disposed in the expulsion orifices 20 and are adapted to open only when air is expelled. The pump 18 comprises a chamber 23 which is divided into a number of small chambers or cells 25 which communicate with each other by means of ventilation holes 26 by partitions 24, the latter

  reinforcing the sole 17 and giving it a damping effect.

  According to this variant of the invention, the heel of the upper 16 comprises air intake means or channels 27, in order to allow

  the easy introduction of air into the orifices 19.

  The operation of the ventilation according to the second variant of the invention is described below. When the person wearing the shoes with the ventilation described above walks, the weight of his body presses on them and thus the air in the cells of the pump 18 flows through the holes. 26 in one direction and is kept under pressure from the orifices 20 to the inside of the shoes 15. The air and the odor prevailing in the latter are expelled by the fresh air of the pump 18. In FIG. Accordingly, when the foot is raised, the shoe 15 is relieved of the weight of the walker, while fresh air from the outside drawn in a single direction through the channels 27 disposed on the heel of the inner portion 16, passes through the orifices 19 in the pump 18. When the weight of the walker again presses the shoe 15, the ventilation action described above is renewed, preventing the shoe 15 from being poorly ventilated and keeping it clean all the time. Note that the cells 25 in the chamber 23 produce a cushioning effect, making the shoe particularly comfortable and preventing the walker from being fatigued. In addition, according to this variant, the orifices 19 being provided inside the shoe 15, there is no fear for the dust, water or other element to penetrate in during the ventilation, the shoe remaining Therefore

clean all the time.

  Fig. 8 and 9 show a third variant according to the present invention. A shoe 28 has an inner portion 29 made of sewn material such as fabric or leather and a soleplate 30 of molded elastic material, such as rubber or synthetic resin. The shoe 28 is provided at the heel 30a of the sole 30 of a pump 31 which is integral and adapted to suck the air inside and expel by pressure and relaxation of the weight of the walker on the heel 30a. The pump 31 has intake ports 32 disposed at the rear end of said heel 30a and the expulsion orifices 33 located at its front end. Intake valves 34 are respectively disposed in the orifices 32 and adapted to be opened only when air is sucked, while expulsion valves 35 are provided respectively in the orifices 33 and adapted to open only when the air is expelled. The sole 30 is provided at the heel of the inner portion 29 of air intake means or channels 36 for allowing the easy introduction of air into the intake ports 32. In addition, said sole comprises a adapted number of air outlets 37 determined according to their diameter, the capacity of the pump or others which extend along the sole 30, with the exception of the heel

  a, for producing fresh air from the pump 31 to the front portion in the boot 28.

  The operation of the ventilation according to this variant is as follows. When a person wearing the shoes 28 provided with a ventilation thus developed, walks, the weight of his body presses on each shoe 28 and then air is introduced under pressure into the pump 31 through the outlets 37, in only one direction going towards the front part of the boot 28. Thus, the air and the odor prevailing in the latter are expelled by the fresh air of the pump 31. Then, when the foot is raised, the shoe 28 is The fresh air from the outside is sucked in one direction, through the channels 36 formed in the heel of the inner portion 29, and passes through the inlet ports 32 into the pump. 31. When the weight again presses the shoe 28, the ventilation action as described above is renewed, avoiding the shoe is poorly ventilated and keeps it clean all the time. Moreover, since the pump 31 produces a cushioning effect, the shoe is remarkably comfortable and prevents the walker from being tired. On the other hand, since the orifices 32, according to this variant, are located inside the shoe 28, there is no fear that dust, water or the like will penetrate into the shoe 28. ventilation of the pump 31, the shoe 28 remaining accordingly

always clean.
