DESCRIPTION

FOOTWEAR WITH WATER EVACUATION SYSTEM

Object of the invention

The invention consists of a shoe that keeps the foot waterproof, and at the same time allows that if water enters the upper part of it, this water can leave or be evacuated by a drainage or evacuation system of the water included within the structure of the shoe itself.

The invention has its field of application within the sector related to the manufacture of footwear, and more specifically with shoes that are waterproof or that have the function of avoiding or minimizing the contact of a user's feet with water.

Background of the invention

Currently a multitude of different types of waterproof shoes are known, basically consisting of a fabric with waterproof characteristics in the outer zone of the footwear. These shoes can have a variable height, depending on the function or the use that you want to give it, ranging from the well-known wellies, which cover the foot above the ankle area, to ski boots that are more rigid and cover also above the ankle, or to racing shoes that leave the ankle free. All these shoes differ from each other in the type of waterproof material or layers of different waterproof materials that surround the structure of the shoe.

In any of these cases there is a common problem, which is that water can sometimes enter the area where the foot is located, either because the exposure to water is very high or due to the simple movement of the foot when walking or when walking. carry out sports practice that, as there is some slack in the contact between the leg and the footwear, allows water to enter the footwear and it cannot be evacuated.

In this sense, certain types of insoles are also known that are micro-perforated, whose function is to allow a foot to breathe, in the same way that footwear that has micro-perforations in the instep or in the lining of the shoe is known, however, these Although shoes may allow perspiration, and even prevent water from entering the footwear, in no case do they allow the water to drain away in the event that the water overflows inside the shoe.

Footwear that have water evacuation systems are also known, such as that described in document US2003136023 where reference is made to footwear with a water evacuation system in its sole, but which has the drawback that it does not protect the user's foot from be in contact with water. Therefore, it cannot be considered to be a waterproof shoe since the user's foot is in contact with the aqueous medium and therefore does not prevent the user's foot from getting wet.

On the other hand, waterproof socks are known that fit the user's foot, preventing the foot from getting wet; however, a user does not have the foot protected in order to be able to walk or do a sport in which it is required that the foot is not in direct contact with the ground. This type of waterproof socks is preferably used in sports where the user is immersed in water, such as sports related to swimming in cold waters or diving.

Socks that fit waterproof boots are also known and internally there are a plurality of sock layers that protect the user's foot from the cold and minimize contact with water. This type of boots is used for sports where the user does not usually walk long distances since the footwear is not comfortable. This type of boots are usually used for high mountain sports where the user is in contact with snow, although what is disclosed in document US2011088280 is also known where a boot to be used in diving sports is described, and where one of the capes or socks can be waterproof features. However, unlike the present invention, this type of boots does not have a direct evacuation system for water that can enter into the structure of the footwear, at least none is known to have such an evacuation system in the sole.

Therefore, taking into account the previous solutions and known footwear in this industrial field, and knowing the previously indicated technical problem that, on the one hand, allows the foot to be dry and not wet, that is, it is a waterproof footwear; and, on the other hand, if water can enter it, the water can be evacuated or drained, without the foot being in contact with said water. Finally, it is important to define that the present invention presents a footwear structure that is not intended for use where the foot is submerged in water at all times, such as scuba diving or swimming, but rather it is footwear intended to be used in maritime or aquatic environments, for example, to be used in a boat for sports or recreational use, or to walk or stroll down the street in case of heavy rain, that is, where the user can be in contact with water continuously, but not with their feet submerged in water at all times.

Description of the invention

The invention consists of a shoe that keeps the foot waterproof and at the same time allows that in the event that water enters the upper part, it leaves through an internal drainage system.

This invention solves the problem that known waterproof shoes are waterproof up to a certain level, at a point, the water can enter if it exceeds the height of the shoe itself, pouring (overflowing) inside.

With the present invention, in the event that water enters the footwear, in no case will the water come into contact with the foot, but rather it will come out between the two layers that form the upper (instep) and draining through holes provided in the sole.

Therefore, it can be said that the footwear object of this invention is comprised of:

a waterproof sock that adjusts to the user's foot, this sock being able to be of different heights depending on the use that is required, being, for example, above the ankle, or below; a sock that is located inside a shoe, and therefore, in a preferred embodiment of the invention, the sock is made of elastic material;

a shoe, comprising an upper or upper covering the foot, a sole and an insole; where the instep is glued to the perimeter of the lower face of the insole; where the template is micro-perforated and comprises a plurality of holes distributed over its entire surface that allows water to be filtered; where the sock is glued to the upper part of the insole, so that an open area is generated between the sock and the instep through which the water that enters the footwear runs off, this water being filtered in its lower part through the holes in the microperforated template; and where the sole of the shoe comprises a plurality of drainage channels that collect the filtered water from the insole and some drainage holes that evacuate the water out of the shoe. These draining holes are preferably located perimeter.

The microperforated insole has a hole morphology that allows internal water drainage and prevents the external entry of water through the lower part of the sole. In this way, water can drain between the sock and the upper of the shoe, filtering the water through the holes in the micro-perforated insole, and being evacuated to the outside through the channels and holes.

In some possible embodiments of the invention, the instep and / or the sole can be made of waterproof material, although the important thing is that the sock is waterproof so that the user has the foot protected.

This invention, compared to other existing technologies in the state of the art, allows the user of the footwear to be in contact with a wet surface, so that the water would not come into contact with the foot, since the foot is protected by the waterproof sock, and the water that may get into the footwear runs between the two layers that make up the upper or upper, filtering through the micro-perforated insole and draining through holes provided in the sole.

This invention is specially designed for activities related to water, both in conventional use and in sports use, and can be used both for work on boats or in ports, as well as for water-related sports such as regattas or rowing sports, although it can be used for any other use where it is required to prevent a user's foot from being wet and / or in contact with water, although it is not intended for uses where the foot is permanently or constantly submerged in water, such as in sports like scuba diving or swimming.

It should be noted that, throughout the description and the claims, the term "comprises" and its variants are not intended to exclude other technical characteristics or additional elements.
