Definitions

  • the invention relates to an insole for shoes with a system of longitudinal and transverse air ducts for ventilation of the feet according to the preamble of claim 1.
  • Foot sweat has been a problem since closed shoes.
  • the rear foot is usually sufficiently ventilated by normal slipping of the shoe, but the midfoot and especially the forefoot with its large number of sweat glands are not. For this reason, generations of inventors have addressed this problem and developed shoes with devices for forced ventilation of the feet in order to increase the health of the feet in various forms.
  • US 861 846 from 1907 shows a two-part ventilation unit.
  • One part is a valve that can be opened and closed by hand, which is inserted in the shoe upper in the area of the ankle.
  • the second part is an insole, in the underside of which a system of longitudinal and transverse grooves or air channels is formed, a plurality of air holes being provided towards the sole of the foot in the transverse channels.
  • the latest studies and considerations have shown that three effects have to be considered for an optimal function of the foot ventilation: the ventilation, the circulation and the swirling of the foot air.
  • the present invention is therefore based on the object of specifying an insole of the type mentioned at the outset which optimally fulfills these three effects.
  • the present invention is not limited to equipping only the lower surface of the insole with channels, air holes and the like, but rather optimizes the shape of all three sole surfaces - lower surface, surface and side surface - in order to achieve the desired effects.
  • the pump chamber in the heel area but in particular also the cavern located under the pad, which acts as an additional pump chamber, and the sealing lips provided therein, which prevent the air from flowing back. It is thereby achieved that the shift in weight when the foot rolls also leads to an effective air circulation inside the shoe.
  • the suction of air is strengthened when the heel area is relieved, while when the heel area is under load, an adequate seal between the insole and the heel cap is ensured.
  • This sealing effect is particularly supported by the fact that sealing wedges are formed on the side of the sole in the heel area.
  • the lower surface of the insole on the three main tread surfaces - heel, inner ball, outer ball - is finely profiled, preferably by means of intersecting fine grooves, in order to enable a certain amount of post-deformation on these zones, which are strongly compressed by the deformation, even during a short wearing period that leads to the individual footbed of the respective wearer. Since there are as many foot shapes as there are face shapes, a hard footbed would only fit perfectly with a few feet; in the overwhelming majority of shoe wearers, the foot would have to adjust to the hard footbed, which would then lead to pressure points and calluses. This is prevented by the present training.
  • these main entrance zones are also ventilated, so that air and temperature compensation is possible.
  • the insole consists of at least two layers of different elasticity.
  • the layer with the higher elasticity forms the bottom surface of the sole into which the channels, pumping chambers, etc. are molded. This ensures the dimensional stability and durability of the air duct system as well as the high walking comfort for the foot.
  • Foam plastic in particular polyethylene, but also cork, cork-latex, latex- Foam and rubber cork.
  • leather, textile, nonwoven, jute or sisal are suitable as foot-friendly material for coating the surface of the insole.
  • the drawing shows a top view of the lower surface 1 of an insole for shoes, consisting of an elastically resilient material, for example a two-layer foamed polyethylene, the layer with the higher density and the higher elasticity forming the lower surface 1.
  • an elastically resilient material for example a two-layer foamed polyethylene
  • a system of chambers and channels is incorporated into the lower surface 1 of the sole.
  • at least one pump chamber 8 can be seen, which is incorporated into the lower surface 1 on the one hand and into the side surface 2 of the insole on the other hand.
  • Radial sealing webs 7 support the air flow directed from the heel region 20 to the tip 23.
  • the heel-side pump chamber 8 feeds heel-side air channels 3, which in turn open into at least one cavern 10, which is formed under an elevated pad.
  • a plurality of sealing lips 9 are designed in the form of webs which are interrupted in the middle and are angled arrow-shaped in the direction of flow.
  • ventilation holes 17 are stamped on the heel side of the webs, which, when the heel is put on, that is to say in the unloaded state of the forefoot and metatarsal region, vent the midfoot region 22. During the further rolling process, these holes 17 are then closed first, so that the air flow directed from the heel area 20 to the tip 23 is maintained without any significant weakening and thus brings about the active ventilation of the forefoot area.
  • longitudinal channels 4 on the forefoot side are fed, which in turn are connected to transverse channels 5.
  • a series of air holes 6 are provided in the forefoot area 23, which guide the air directly to the underside of the foot.
  • the surface of the insole that is not recognizable in the drawing is coated with a foot-friendly material, for example leather or textile.
  • the inner ball is lowered compared to the outer ball, which creates a sufficient pronation effect, as is required for shoes with a low heel.
  • the forefoot area of the insole has no shell formation either to the side or to the tip; instead, the sole becomes thinner towards the edges. This ensures that enough spaces remain in the shoe that are not fully filled by the foot to allow the necessary ventilation (V), circulation (Z) and swirling (V) of the foot's air (VZV system).
  • the back of the foot is only designed as a light shell in an asymmetrical shape, but the supination effect is achieved below the scaphoid due to increased sole volume.
  • the lower surface 1 of the insole is finely profiled on the three main tread surfaces - inner ball 14, outer ball 15 and heel 16, by means of intersecting fine grooves which are connected to the channel system 3, 4, 5.
  • This system of fine grooves initially allows a certain amount of re-shaping even during a short wearing period, which leads to the individual footbed of the respective shoe wearer. This means that it is not the foot that adapts to the hard footbed, but the elastic / plastically flexible footbed that adapts to the foot.
  • these main tread surfaces 14, 15, 16 are additionally ventilated, which leads to improved temperature compensation.
  • the air is distributed in the longitudinal channels 4 and transverse channels 5 and is pressed through the air holes 6 under the sole of the foot.
  • the fine groove systems 14, 15 are aerated in the area of the front main tread surfaces.
  • the air pumped into the forefoot area 23 and under the foot surfaces causes the active ventilation, circulation and swirling effect (VZV effect).
  • VZV effect active ventilation, circulation and swirling effect
  • the foot air flows back between the sole surface and the foot surface to the heel area 20, where it mixes with the fresh air entering through the slipping of the shoe before the air cycle begins again.
  • the mode of operation of the channel and chamber system according to the invention can be proven by adding a little talcum powder to the heel-side pump chamber 8. After just a few steps you can see talc stains on the black stocking in the area of the air holes 6, 17.
  • These grooves preferably pump around air that can enter between the foot and the shaft end. However, they are not connected to the main duct system.
