Definitions

  • This invention relates toan inner sole. More particularly this invention relates to an inner sole which prevents the toes from athlete s foot by passing air compulsorily through the toes and by keeping them dry.
  • An object of the present invention is to provide an inner sole which can prevent the toes from athletes foot.
  • a further object of the present invention is to provide an inner sole which can keep the toes dry by passing air compulsorily through them in walking.
  • a still further object of the present invention is to provide an inner sole which makes man comfortable in walking.
  • FIG. 1 is a plan view of an inner sole. 7
  • FIG. 2 is a plan view of an elastic member which is placed between an upper sheet of leather and a lower sheet of leather.
  • FIG. '3 is a perspective view showing the inner part of 3 5 an inner sole.
  • FIG. 4 is a, cross-sectional view taken along the line II II in FIG. 1.
  • FIG. 5 is a cross-sectional view taken along the line II II in FIG. 1 under the pressure of the foot.
  • FIG. 6 is a cross-sectional view taken along the line III III in FIG. 1.
  • FIG. 7 is a cross-sectional view taken along the line III III in FIG. 1 under the pressure of the foot.
  • FIG. 8 is a perspective view of projecting parts of an elastic member and a valve attached to them on an enlarged scale wherein the valve is the same open condition as that of FIG. 7.
  • FIG. 9 is a perspective view of projecting parts of an elastic member and a valve attached to one of them on an enlarged scale wherein the valve is an open condition under the pressure of the foot.
  • DETAILED DESCRIPTION may be covered with net-like materials.
  • the shapes of 6 these openings may be rectangular, elliptic, and the like.
  • a valve 8 which can easily open downwards and shut again easily.
  • leather-like materials such as artificial leather may also be used.
  • the elastic member 3 takes the form as shown in FIG. 2.
  • the elastic member soft rubber, foamed polystyrene and the like may be used.
  • the lower sheet of leather 2 may attach, if necessary, a piece of sponge-like material 9, thereto at the front part thereof.
  • leather-like materials such as artificial leather may also be used.
  • a piece of tape 10 combines the upper sheet of leather 1, the elastic member 3 and the lower sheet of leather 2.
  • the tape such materials as nylon, cloth and the like may be used.
  • both the compartment a and b are filled with air.
  • the air in the compartment a is compressed, which makes the valve 8 shut and the valve 5 open.
  • the air in the compartment 0 flows to the room b through the opened valve 5 and then the air in the room b flows to the toes through the openings 7.
  • the upper sheet of leather 1- rises to the original level by the recovering strength of the elastic member 3.
  • the resulting reduced pressure in the compartment a makes the valve 5 shut and the valve 8 open and air flows through the opened valve 8 to the compartment a and fills it.
  • the openings 7 may be set between each toe, or may be set as shown in FIG. 1.
  • the inner sole of the present invention When the inner sole of the present invention is placed on the insole of a shoe and used for walking, the toes are kept dry by air stream resulted from the special operation of the inner sole as hereinbefore mentioned, even when the toes remain in the shoe for a long period. Therefore, the inner sole of the present invention can not only prevent the foot from athletes foot but also be used for remedy of it. Moreover, when perfume is impregnated in the sponge-like material 9, the hygienic toes can be covered with pleasant smell. Further the elastic member 3 of the inner sole hardly gives fatigue to the foot in walking. Thus the inner sole of the present invention is preferable to the foot from the viewpoint of human engineering.
  • An inner sole with a shank and toe comprising in combination:
  • an elastic member (3) of rectangular cross-section placed between said upper and lower sheets of leather between the rims thereof and having two inwardly projecting parts (4) holding a second valve (5) at the central part thereof, said projecting parts and second valve separating the vacant space between said upper and lower sheets into a forward covered with net-like material.
