Definitions

  • the invention relates to a ventilation insert for ventilation of textiles or shoes and a ventilated shoe comprising an outsole, an insole, an insole, an outsole connected to the shoe upper and ventilation openings in or in front of which a ventilation insert is arranged, as well as an insert with venting device for shoes ,
  • Open or porous materials still provide the most effective means of air exchange and the associated removal of water vapor and heat. Openings or material breakthroughs, for example inside the shoe upper, in some solutions have closure options or covering elements which, after manual closure or opening, prevent water from entering or allow targeted ventilation. Corresponding cover elements are fastened for example by zip or Velcro fasteners in their position or they are more permanent part of shoes and are changed by pivotal or sliding movement in position. Furthermore, it is possible to use fiber layers, which permanently cover openings and thus prevents ingress of water.
  • shoes are also partially equipped with ventilation options.
  • the ventilation in previously known ventilated shoes is essentially by the use of open-pore materials, microfibers or vents.
  • Some types of shoes have openings in the area of the upper part of the shoe which are in part connected with structures, for example lamellae, which allow improved supply of outside air or outward penetration of water vapor.
  • Other shoes have openings in the soles of the shoes. In order to prevent ingress of water and foreign bodies, these openings are covered for example with a special membrane or a microfiber, which is associated with the disadvantages already described.
  • Mechanical ventilated shoes help ventilate the shoe interior with kinetic energy. Some of these solutions sometimes use quite complex mechanical internal structures. Mechanical ventilation systems inside shoes have proven to be quite vulnerable, expensive and thus expensive to manufacture. In addition, it is disadvantageous if an air supply and a consequent reduction in the humidity in the shoe interior is only possible when the wearer is moving.
  • a corresponding ventilated shoe is from the European patent application EP 1 500 341 A1 known.
  • This ventilated shoe features a footbed insert with a pump chamber at the back.

In this case, such ventilation inserts or ventilation systems for shoes in a structurally simple manner, can be produced inexpensively and from health-friendly materials. The ventilation and dehumidification of the shoe interior should also be possible regardless of a movement of the foot.

  • FIG. 12 shows the course of air when the shoe is used according to FIG. 11.
  • the used air from inside the shoe flows outward along the arrows c through the ventilation insert 4. Due to the negative pressure arising in the shoe, fresh air is transported along the arrows a through the air inlet opening 17 into the cavities 11a and 11b. These pass along the arrows b via the air ducts 13 through the air outlet openings 16 in the shoe interior.
  • the spacers 10 prevent closure of the outlet openings 16 caused by a force effect.
  • FIG. 13 shows a longitudinal section through a further embodiment of a ventilated shoe according to the invention without ventilation inserts.
  • the shoe has an outsole 1, an insole 2 arranged above it and an insole 3 arranged above the insole.
  • the outsole 1 is connected to a shoe upper 9 with ventilation opening 4.
  • a cavity 11 is arranged, which has an outlet opening 16 and air inlet openings 17a in the insole 2 with a gap between the insole 2 and the insole 3 is connected.
  • the insole is at least in the front region via air inlet openings 17b connected to the shoe interior.
  • Figure 14a shows a plan view of an insert with ventilation devices.
  • the insert has on its top and bottom elastic molded parts 24 which are connected to each other via the connecting devices 5.
  • In the area of the air inlet openings 17 are also concavities 23, which are formed here of the material of the elastic molding 24.
  • the indentations 23 prevent the insole 3 from permanently sticking to the elastic molded part 24 when the force is applied and, if necessary, closing the outlet openings. From the insert lead two air ducts 13, at the end of which an air outlet opening 16 is located.
  • FIG. 14b shows a section of the insert with ventilation device from FIG. 14a.
  • damping inserts 21 are located inside the insert, between which an absorber element 22 with absorber 14 embedded therein is placed.
  • the interior of the insert is formed by a cavity 11.
  • the damping inserts 21 are not arranged here in the region of the air inlet openings 17.
  • FIG 15a shows a further embodiment of the insert with ventilation device in a plan view.
  • a compensation surface 25 is attached above the elastic molding 24 while a compensation surface 25 is attached.
  • air outlet openings 16 are located in the elastic molded part, which are arranged centrally in use between the compensation surface 24 are. From the insert leads an air duct 13, at the end of which an air inlet opening 17 is located.
  • FIG. 15b shows a section through the insert from FIG. 15a. It can be seen that the compensation surface 25 extends over the entire surface of the upper elastic molding. Only in the region of the air outlet opening 16 no molding is arranged.
