PATENT DESCRIPTION FOR INDUSTRIAL INVENTION HAVING THE TITLE: ANATOMICAL INSOLE FOR FOOT VENTLATION

Currently on the market there are no insoles with pads and tubes able to ventilate the foot during walking; nevertheless, the function of the insole is to guarantee the user greater comfort during walking.

Currently, the types of existing insoles are:

- Patent N. EP 1623643 where the insole has 2 pads in the heel and in the front part called metatarsal which only have the function of cushioning walking: Our pads not only cushion walking but also ventilate the foot through tubes.

Patent No. WO9947014 where the insole in question has an air pocket connected to an elastic modular compound. During walking, the movement of the air increases comfort, but does not favor ventilation in the foot. (Our insole, therefore having pads and tubes, allows air to escape during walking and increases comfort).

In table N.l our description will be reported

A) Pad / inflation (TABLE N.l), positioned on the forefoot and heel area in contact (TABLE N.2), in the upper part, with the user's foot;

B) Pad / inflation, positioned on the forefoot and heel area in contact, in the lower part, with the assembly insole (see construction of the sole).

C) Pipes in pvc or other material (TABLE N.l), connected to

Cuscinctti / swellings for the passage of air throughout the area of the

foot / ventilation. The ducts are connected to each reference pad, positioned in the forefoot area and in the heel area.

Currently, the anatomical insoles on the market, according to the known art, do not have any type of channel designed for the passage of air. They are also not connected to any type of pad or swelling in the forefoot area, also called the metatarsal area, and in the de! heel.

These pads and channels for the passage of air are an integral part of the insole, which in the lower part is in contact with the mounting insole of the upper (see construction of the sole) and in the upper part is in direct contact with the foot of the upper. 'user. The latter, thanks to the passage of air from the pads through the passage channels, benefits from ventilation throughout the foot area.

This insole, constructed as described above, unlike other anatomical insoles, according to the known art, has two swellings also called pads, which are positioned one on the forefoot area also called metatarsal and one on the heel area. Both bearings are connected to the so-called channels for the passage of air which can be described as channels / tubes in pvc material or in any other material. Their function is to let the air pass from the cushion to the entire foot area in order to have complete and optimal ventilation throughout the foot area.

With the use of this creation and invention of the insole, the user will have the benefit of ventilation throughout the foot area, simply thanks to normal walking.

In fact, during the walking phase, the foot flexes naturally and, with the natural shift of the user's weight, pressure will be created in both pads, both in the forefoot area, also called metatarsal, and in the heel area. . The pressure formed inside the pads will cause the air to escape through the air ducts / tubes, which will make complete ventilation of the foot possible.

This type of invention of the insole can be removable or fixed used to replace the assembly insole where the upper of the shoe is mounted (non-removable) and can be inserted inside any type of footwear.

The bearings with all the technical characteristics mentioned in the present patent can be with or without the relative air channels, they can have all shapes and sizes, they can be in all materials, and finally they can also be present in only one area of the foot. (forefoot area, also called metatarsal and / or heel area).

The insole, as described above, consists in the upper part, which is in direct contact with the foot (see table I), by swellings or pads and both have a rise of about 3/4 mm, both in the forefoot area, also called metatarsal, which is in the heel area. The lower part of the sole, on the other hand, is in direct contact with the assembly insole (see table 2). Both pads / swellings have a hollow of about 3/4 mm both in the forefoot area, also called metatarsal, and in the heel area.

Inside both pads / inflations are positioned both in the forefoot area also called metatarsal, and in the heel area, there are inserts that can be of any material (for example latex, ultra light tpr, and padding with memory ) and are of the same shape and size as the pads / bulges. The material used has an elastic memory that lasts over time, so that the user can benefit from this function and this memory throughout the use of the insole.

These inserts are also made up of several steel springs, of various shapes and sizes. Their function is to cushion the weight of the user's body while walking.

A protective film of strong and anti-puncture material has been applied to these inserts so that the steel springs, positioned in both bearings, cannot pierce the external material of which the insole is composed and come into contact with the foot of the foot. 'user.

Both bearings, with their specific technical characteristics described above (see inserts, springs and protective film), have connection channels / tubes in PVC, or in any other material, which are connected to holes designed for the exit of the air and to restore it inside the bearings.

Claims (3)

CLAIMS: 1) Anatomic footbed for the ventilation of the foot equipped with pads in the metatarsal and heel area characterized by the fact of having ducts in plastic or similar material connected to said pads suitable for the passage of air in the whole area of the foot. 2) Insole as per claim 1 characterized by the fact that during the walking phase, the foot cleans itself naturally and, with the natural displacement of the user's weight, pressure will be created in both pads, both in the forefoot area , also called metatarsal, both in the heel area. The pressure formed inside the pads will cause the air to escape through the air passage channels / tubes, which will make it possible to fully ventilate the foot. 3) Insole as per the previous claims characterized by the fact that the bearings may have inside them elastic elements, preferably springs, designed to allow the action of air.
