Abstract

The invention relates to a shoe having a sole and a upper. On the shoe upper,at one side of the shoe there has been mounted a non-­return inlet valve and at the other side there has been mounted a non-­return outlet valve for aerating the shoe during use.

Description

  • The invention relates to a shoe having a sole and a shoe upper.
  • There are known shoes having air ventilation holes through which circulate fresh air and stale air.The ventilation effect of said know structures is unsatisfactory and there is also a risk that water comes inside the shoes when said shoes are used on a rainy day.
  • According the invention on the shoe upper there has been provided a first non return valve permitting only flow of air from the atmosphere into the interior of the shoe and a second non return valve permitting only flow of air from the interior of the shoe towards the atmosphere.
  • In this way there could be obtained an effective aerating of the interior of the shoeduring use.
  • The objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings,in which
    • Fig. 1 shows a shoe according the invention in perspective view.
    • Fig. 2 shows a sectional view of the shoe according line A-A in Fig. 1.
    • Fig 3 shows a sectional view of the shoe according line B-B in Fig. 1
    • Fig.4 shows a perspective view of a non return valve permitting flow of air out of the interior of the shoe.
    • Fig. 5 shows a perspective view of a non return valve permitting flow of air towards the interior of the shoe.
    • Fig. 6 shows a perspective view of an insole of the shoe.
    • Fig. 7 shows a perspective view of an assembled non return valve
  • As shown in the figures on one side of the shoe there have been provided on the outside upper 9 two one way valves A and A′ whilst on the other side of the shoe on the inside upper there have been provided in a similair way two one way valves B and B′.
  • The one way valves A and A′ permitting only flow of air from the atmosphere into the interior of the shoe each comprise a cap 1 with various separated inlet holes 3.The cap 1 has been provided with a groove 2 for accomodating an annular rim 8 united with a plate shaped part 7.
  • In the area of the plate shaped part 7 surrounded oy the rim 8 there has been provided airholes 6.Between the plate shaped part7 an the the cap 1 there has been arranged a plate 4 and a spring 5 so that the spring 5 tends to push the plate 4 against the cap 1 for preventing flow of air through the valve.As appears from fig.1 the valve is mounted on the shoe by fixing the plate shaped parts between parts of the upper 9.
  • The structure of the non return valves B and B′ is similar to the structure of valves A and A′ and the various parts of said valves B and B′ have been indicated with the same reference numbers as corresponding parts of the valves A and A′ with addition of a suffix.
  • However from the drawings it will be clear that the valves B and B′ mounted in the inside upper only admit flow of air from the inside of the shoe towards the atmosphere.
  • Further in the shoe there has been arranged an insole 14 having a sill 15 at its outer edge and extending partly along the inner side of the inside upper.
  • The interior of the shoe is in communication with passages 12 arranged in the lower side of the insole 14 through holes 11.Passages 12 are in communication with the valve B′ through passages extending along parts 13 of the insole 14 (fig. 2) .
  • When the user of the shoes according the invention steps on the ground ,the stale and warm air which is inside the airway passages (12) of insole (14) will be forced out through the one way air-out valve(B′) via arch parts (13)of insole 14 and stale air inside the shoe will be forced out through the one way air-out valve(B) of the front part.
  • When ,on the other hand the user of the shoes according the in­vention put his foot forward only fresh air will flow into the interior of the shoe through non return valves A and A′ which are stitched on the front part and middle part of outside upper 9.
  • So by the arrangement according the invention there is obtained an one way air ventilatione continuously during walking as only fresh air flows into the shoes through the one way valves A,A′ and only stale air flows out through the one way valves B,B′.
  • One way valve B′ ,which is on the middle part of inside upper, discharges the stale air out concentrated in the passages 12 and 13 of insole 14 in every step.
  • One way valve B which is on the front part of inside upper,dischar­ges the stale air out concentrated in shoe inside operating with the in­sole which prevents the stale air of passage 12 and air holes 11 from flow backward with the frame sill 15 of the insole 14.
