Technical Field
The shoes ventilation system is suitable for almost all types of shoes, except for banded or other open shoes.
Background Art
The systems with valves so far used in shoes are complicated and large. Summary of Invention
In the shoes ventilation system, at least one longitudinal hole 1 extends from the space of the heel of the foot to the space of the toe of the foot through an elastic layer of the of tread surface 2 which is in contact with the sole of the foot in the shoe. The rear end of the longitudinal hole 1 has an air inlet in the space of the heel. The front end of the longitudinal hole 1 has an air outlet in the space of the toe. During the beginning step, when the heel of the foot presses against the tread surface 2, the rear end of the longitudinal hole 1 is compressed and the air inlet therefore closed. As the sole of the foot gradually treads on the tread surface 2, the longitudinal hole 1 is gradually compressed from the heel area towards the toe area and air is forced out of the longitudinal hole 1 into the inner toe space of the shoe. At the end of the step, when the toe of the tread surface 2 is compressed, the front end of the longitudinal hole 1 is compressed and the air outlet closed, but the hee! of the foot is unloaded and the air inlet into the longitudinal hole 1 is opened. By gradually unloading the foot on the tread surface 2 from the heel towards the toe, air is sucked into the longitudinal hole 1.
The rear end of the longitudinal hole 1 is opened in the space of the heel of the foot at least one inlet hole 3.
The front end of the longitudinal hole 1 is opened in the space of the toe of the foot at least one outlet hole 4.
More longitudinal holes 1 are connected by at least one connecting hole 5 at the rear ends of the longitudinal holes 1 below the heel of the foot.
More longitudinal holes 1 are connected by at least one connecting hole 5 at the front ends of the longitudinal holes 1 below the toe of the foot.
Between the connecting hole 5 at the rear ends of the longitudinal holes 1 and the connecting hole 5 at the front ends of the longitudinal holes 1 there are other connecting holes 5 connecting the longitudinal holes 1.
An inlet hole 6 from the side air inlet 7, located in the area of the arched part of the sole, is connected to the connecting hole 5 at the rear ends of the longitudinal holes 1. A vertical extension 8 is connected to the inlet hole 6 in the area of the arched part of the sole in front of the heel of the foot so that the inlet hole 6 continues with the vertical extension 8 upwards to the edge of the shoe, where the side air inlet 7 is located.
The inlet hole 6 has, in the vertical extension 8, a solid wall so that the inlet hole 6 is not compressed n the vertical extension 8 during walk.
The main 21 elastic layer of the tread surface 2 is made of an elastic foam material.
At least the surface of the hole has an elastic surface layer impermeable to air.
The tread surface 2 with the ventilation system is a permanent part of the shoe.
At least the main 21 elastic layer of the tread surface 2 with the ventilation system is a separate insole inserted in the shoe.
The main 21 elastic layer of the tread surface 2 has holes of the ventilation system in surface, so the holes are laterally opened and form open grooves 11. The grooves 11 can have a semicircular cross- section.
The grooves 11 of the main 21 elastic layer of the tread surface 2 are covered with a flexible lid 22 so that creating at least longitudinal holes 1 and connecting holes 5.
The tread surface 2 is composed only of the main 21 elastic layer with grooves 11 downwards and in this position it is inserted in the shoe as an insole.
The tread surface 2 is composed of the main 21 flexible layer and a flexible lid 22 which are not fixed to each other and are jointly inserted in the shoe as an insole.
The tread surface 2 is composed of the main 21 flexible layer and a flexible lid 22 which are fixed to each other and are inserted in the shoe as an insoie.
The tread surface 2 can have the main 21 elastic layer at the bottom and the lid at the top or vice versa. Alternatively, two main 21 elastic layers can have grooves 11 arranged oppositely to create holes together.
The tread surface 2, which is in contact with the sole of the foot, can be made of leather or fabric. Likewise, the surface of the flexible lid 22, which is in contact with the sole of the foot, can be made of leather or fabric.
A flexible tube with an air outlet from an electric fan can be attached to the side inlet 2ยท The advantage of this shoes ventilation system is its simplicity. The version in the form of an insole is particularly advantageous in terms of production and versatility.
