Definitions

  • the application relates to a, preferably removable, insole for shoes.
  • Insoles for shoes are known in principle.
  • the foot must be additionally damped to minimize the joint loads of the wearer.
  • this attenuation should not be so strong that the energy consumption when walking or running is too high or a "spongy" feeling arises.
  • the sole should adapt as well as possible to the foot, but still be durable and do not exert too much back pressure on the foot.
  • the surface layer is arranged so that the foot of the carrier rests on this surface layer.
  • the vomstellschaum für is regularly between the surface layer and the activated carbon layer, between the three layers mentioned also further intermediate layers may be arranged or as the top or bottom layer other layers may be eligible (for example, temperature barrier layers / disinfecting layers, etc.).
  • the rebound foam layer has favorable viscoelastic material properties. This may be provided, for example, by developing this layer from a molded foam based on a natural or synthetic latex material was, as used for example for mattresses. By body heat and body weight a favorable pressure distribution is ensured on this tillstellschaum Mrs, whereby pressure points on particularly vulnerable body parts (for example, the bale / heel) are reduced. The recovery properties ensure that the foam adapts "slowly" to the foot, but that shape (ie as an individual footbed) then remains longer. This does not lead to an immediate "springback" of conventional foam materials.
  • the insole is thus breathable, sweat absorbent, comfortable to wear and also, even when wet, equipped with excellent resilience.
  • the surface layer may be made of leather, preferably goatskin, which is particularly fine.
  • the layer can be provided with holes for the return foam layer in order to improve the respiratory behavior once again.
  • the leather layer may have been produced in various ways, for example by vegetable tanning or chrome tanning. In this layer different thicknesses are possible, preferably between 0.5 and 2 mm, particularly preferably between 0.8 and 1 mm.
  • the surface layer may also be made of a plastic material or of a textile material, in these cases, the insole is washable, eg at 30 ° C.
  • the reset foam layer is preferably as viscoelastic system designed with an open-pored / closed-pore plastic or latex material.
  • the resilience of the remindstellschaum Mrs is preferably such that with static compression to 50% of the normal volume (at atmospheric pressure and 20 ° C ambient temperature) recovery after abrupt removal of the load takes place so that after eight hours more than 95% of the original normal volume automatically restored are. All in all, this static load is particularly noticeable when standing for a long time, for example in guards or policemen. It is advantageous that the footbed anatomically adapts during the day and (for example, when removing the insoles overnight) is normalized again, so that the same process can begin the next day.
  • the continuous load resistance of the material is also very good.
  • the resilience under dynamic load (measured according to the standards of the Test and Research Institute Pirmasens) is less than 60, preferably less than 50% permanent deformation after 100,000 load cycles with 80 N per cm 2 . After 24 hours of relief, the permanent deformation is only less than 5%, preferably less than 3%.
  • the density of the remindstellschaum Mrs is in the unloaded state at 20 ° C and North pressure preferably between 0.1 and 0.3 g / cm 2 .
  • the water vapor permeability is preferably 9 to 14 mg / cm 2 x hour, the specific water vapor absorption 2.5 to 5 mg cm 2 x 8 hours.
  • the air permeability analogous to DIN 9237, measured at 0.01 bar is preferably more than 1.5 to 3 x 10 6 l / m 2 x hour.
  • the hardness of the material can be set differently, here are recommended (depending on whether they are children / adults or even work shoes) hardening from 5 to 25 Shore A, preferably 13 to 17 Shore A.
  • the activated carbon layer is preferably a polyurethane foam treated with activated carbon particles and / or activated carbon paste or a corresponding latex material.
  • This foam or latex material additionally has, if appropriate, a textile carrier layer on its top and / or bottom side, wherein particularly preferably a bond is provided between the foam layer / latex layer and the textile layer.
  • the thickness of the activated carbon layer is preferably 1 to 4 mm, more preferably 1.8 to 2.2 mm.
  • the specific surface area is preferably more than 150 m 2 per gram according to the Brunnauer / Emmett / Teller model.
  • the fluorobenzene absorption of the activated carbon layer is preferably more than 10 g / m 2 , particularly preferably more than 20 g / m 2 .
  • the activated carbon layer preferably has anti-skid knobs on the underside, which may be made of a latex material or of a synthetic plastic polymer, preferably being approximately equidistant with one to fifteen nubs per cm 2 of surface area.
  • a further preferred embodiment provides that the surface layer, the return foam layer as well as the activated carbon layer are connected to each other over the entire surface, ie have approximately the same total area. In a modification to this, it is also possible that these only partially overlap.
  • a layer of leather / metal or plastic may be attached for reinforcement below the activated carbon layer (ie on the side facing away from the return foam layer side of the activated carbon layer). This is preferably given only over a part of the area, for example in the rear area of the sole.
  • a curvature can also be specified here for the purpose of improving the elastic properties or for adapting to the shape of the foot (for example, one from the shoe underside), a concave curvature being provided.
  • thermal barrier layer for example of aluminum, or a disinfecting layer (with a fungicidal / bactericidal material) is provided.
  • FIGS. 1 to 3 show different views or a section of an insole according to the invention 3.
  • the top is seen with a beige, vegetable tanned goat leather layer 1.
  • This goatskin layer has holes 7 to an underlying activated carbon layer. 4
  • FIG. 2 shows the bottom of the sole here a curved reinforcing layer 5 is shown from a technical plastic for shaping and supporting the insole.
  • the insole has this reinforcing layer 5 only in a partial area (in the rear area).
  • the remaining layers are the same size and connected over the entire surface. You can also see the activated carbon layer 4, which has on its side facing away from the foot nubs 6 made of latex material.
  • the thickness of the leather layer 1 here is 0.9 mm.
  • the rebound foam layer 2 is a viscoelastic system of a technical latex material. The resilience of this layer is such that at a Recovery over a prolonged period (five hours) to 50% of the normal volume under normal conditions (20 ° C and normal pressure) with sudden discharge is such that more than 95% of the normal volume is automatically accepted after 8 hours of removal of the load Compression.
  • the resilience at a dynamic load of 80 N / cm 2 and 100,000 load cycles is about 58%, after 24 hours of unloading, the permanent set is about 3%.
  • the density of the material here is 0.2 g / cm 2
  • the water vapor permeability is 12 mg / cm 2 x hour
  • the specific water vapor absorption capacity 3 mg / cm 2 x 8 hours
  • the Shore A hardness is 15.
  • the activated carbon layer is a polyurethane foam treated with activated carbon paste, textile backing layers, not shown here, being arranged on the upper and lower side for stabilization and durability.
  • the total thickness of the activated carbon layer, including textile reinforcement layers, is 2.2 mm. In the present case, there is only one textile reinforcement layer on the underside, the total thickness is 2 ⁇ 0.2 mm.
  • the BET surface area of the activated carbon layer used is more than 150 m 2 , the fluorobenzene absorption more than 15 g / m 2 .
  • the activated carbon layer 4 with the nubs 6 is very anti-slip to arrange in the shoe, here five knobs per cm 2 area are arranged here.
