Description

12:E q. dl::,- c) C A k FOOTWEAR SOLE The invention relates to varied

footwear soles for sports footwear, shoes, zilitary shoes, safety shoes and mountain-clirbing shoes etc. that have uppers.

The invention is to provide footwear sole which can be fixed to the heel to promote cushion function and prevent walter to get in the footwear in had weather utilizing waterproof and ventilation part applied at the front of the heel, providing good ventilation and further afford shock absorption effect by means of rib applied at shank of out-sole in case of shoes, military shoes, safety shoes and mountain-climbing shoes.

Pulbication No. 82-2591 of utility patent (U.S. Patent No.

4499672, Pulbic Notice No. 80-31524 (85. 9. 20) of Japanese utility Patent) revealed a out-sole and mid-sole providing 1 i 1 1 ventilation and shock absorption which was jointed to the i i out-sole by means of projections.

The out-sole had circular projection on its surface and the circular projections applied at the heel had soze of air entry while the mid-sole projections on the outskirts i of its reverse side and lots of punched ventilation holds on its innerside as well.

Publication He. 82-2592 of utility patent showed a i i i back-sole of footwear with air entry connected to air i i passage way that was prepared on the heel.

Opening No. 90-2356 of utility patent also showed a i footwear sole providing of ventilation and shock absorption 1 i which a ventilation cap having connective joint cap be f iXed to.

Heel side part of the complezented sole having cork i layer on its surface formed a circular curve part and on the reverseside of its projections for cushion were prepared while on the front of it the round projected part were formed and projections for cushion as well, with ventilation holes punched.

Front part of zid-sole has the space part with the round projected part prepared at the inner side of the outskirt.

The surface of dut-sole has vertical and horizontal air inhalation way and air supply way while frontend part of air supply way was connected to the air inhalation room and joint part of the air inhalation way had punched ventilation hole.

Publication No. 90-2537 of utility patent revealed footwear sole providing ventilation and shock absorption which had airing cap fitted to its receptacle. The front part of soft cushion rid-sole has punched holes while the reverseside of it shock-absorbing projections.

Back part of the reverse side of the cushioned mid-sole had circular projections while back part of the out-sole air- inhalation and exhalation entry. The projected part on the front of the heel was prepared for fitting to the airing cap which has ventilation holes and receptacles.

Further, publication no. 90-2538 of utility patent revealed footwear sole providing ventilation and shock 1 v i i i i 1 1 absorption which had heel cushioned pad on the surface of i out-sole. Soft cushioned pad with surface of cork layer was to be fitted to the inside of the cut-part which was pre- i i 1 i pared at the front part of hard texon board mid-sole.

The surface of cushioned pad was attached to texon 'board i aid-sole by textile net. The reverseside of cushioned pad had i 1 i cushioned projections through which ventilation holes lead.

1 The.. reverses ide of heel cushioned pad having curve part i i 1 on its surface contained air inhalation room and air-supply way. The inner part of air inhalation roor had shock- absorbing projections.

The projected part of air inhalation 'and exhalation entry that lead to an ventilation roon and air-supply way had punched ventilation holes, and airing cap having holeing joints was fitted to the out-sole.

The above-described technology allows good ventilation within footwear as the airing cap has ventilation holes but can not effectively prevent water from getting into the foot- i wear in bad weather.

1 1 In addition, the shock absorbing material at the heel is not fitted in the inside of the heel of the sole and the effective shock absorption at the heel of the sole can not be expected.

Further. the fact that the cushioned shock absorbing material for the heel is not fitted at texon board can neither afford good shock absorbing effect to the back- side of th.e foot nor rezove the negative factors for the shock absorption in case of the sole of footwear having heel such as that of shoes, ailitary shoes, safety shoes and mountain-clirbing shoes due to the hard iron for waist fitted at texon board.

This invention aired at improving and reroving the above-rentioned drawbac,k can afford the effective shock absorbing effect to the backside of foot with the mid-sole fitted into the backside of the footwear.

The mid-sole has varied horseshoes-shaped shock-absorb- ing. material with the excellent elasticity (heel of out sole in case of shoes).

1 i i i The innerside of the shock absorbing material for the heel is hol.low but the sectional parts of the both side forr P i the closed pipe types.

The shock absorbing material of pipe type has flange at the upper & lower parts facing outside which can lighte4 the stock to the backside of foot in walk.

i i The shock absorbing material at the heel is horseshoes- shaped. The sectional part of the innerside is closed while the unit sectional part facing outside foras the 1 plural layer of the opened circular arc or hexagonal shape.

may have The invention / a feature that buoyancy plate fitted at the inner part of waterproof and ventilation portion pre- vents water from getting into the sole in bad weather by means - of its rising due to buoyancy which close inhalation and exha- lation entry leading to the sole.

may have The invention / another feature that subsiding of the buoyancy plate due to exhausting force when the air in the sole 1 is exhausted can exhaust water in waterproof and ventilation part through ventilation entry.

Code no. 74 and 74 'are ventilation holes punched on the 1 1 sheet of the cushioned air bag and Code no. 76 and 76 1 are supporting parts for the forming groove of mold which is used when the shock absorbing heel material(14) is fixed to the heel 23 - part of the rid-sole(l).

The pdcessing steps of the invention are as follows In Figure 1, the shock absorbing heel material(14), first of all, is to be fixed between the upper flap and the lower one (13)(13 ') of the rid-sole(l) and the water proof and ventila- tion part(U) to be fixed in the reception groove. - 1 The ventilation part(47) applied at the rear wall(42) of the water proof and ventilation part(12) is to be connected to the air way(10).

As the ventilation entry(45) punched on the front wall (42 ") of the water proof and ventilation part(12) faces the outside of the mid-sole, the air from the outside can be induced into the ventilation entry(45).

The air is to get through the ventilation rooz(C) by means of the inhalation and exhalation entry(46) and to pass the air way(10) by the ventilation part(C). The air gets into the ventilation hole(3) at the air ventilation roor(2) and then reach the air compression room(16) through the ventilation way (19) existing at the reverse side of the rid-sole(l).

i The satisfactory air-inhalation stated above can be made when the out-sole(24) is fixed to the reverse side of the mid- sole(l) with the cushioned shock absorbing zaterial(g) fixed on i the surface of the mid-sole so as to have the middle of the rece- i ption rooz(6) take the circular arc shape afid texon board (20) is also fixed with the inner sole(22) fixed on the surface of.

i i i i i texon board.

The..process of the air-exhalation is undergone vice versa.

i i 1 In case of s.ports shoes as well as boots, military shoes and safety shoes etc., it is desirable that the footwear sole has 1 a device affording the possible shock absorbing means to the heel 1 as back part of the foot receives such shock in walk and exercise i i i i i taking.

So, the shock aburbing heel zaterial(A) that is horse- i i shoes-shaped with the upper and lower flanges(15)(15 1) is fixed at the back part of the footwear sole in this invention and on i the raterial the circular arc-shaped(7) cushioned shock absorbing 1 inaterial(g) is fixed with flanges(8)(8) getting into the rece- ption room and further, at the reverse side of it the air compre- ssion room(16) is formed with wall(17).

Due to the corPosition as described above, the hollow shock absorbing. heel zaterial(A), in walk, is contracted and with the upper and lower flanges(15)(15 1) receiving load, the air in the air compression rooz(16) moves toward the front part due- to the contraction of the wall(17).

7 BY means of the course stated above, the heel part of the sole can absorbe the shock ideally and the shock transmitted to the back part of foot is so little that the fatigue feeling due to the shock from footwear can be dissolved.

The cushioned airbags(23)(23 ') can be fitted to the inner-sole(22) as well and the air compression in the cushioned airbag(23X23 ') can not only absorve the shock but give the elastic effect by means of the elasiticity of the cushioned airbag.

The shock to the sole of a foot can be alleviated by means of the air room(75).

In the water-proof and ventilation part(12) the buoyancy plate(48) is to be put on the seperation projection(49) and does not cause any tronble in terns of air ventilation in good 1 i i i i i i i weather while in bad weather the water-perreating through the ventilation entry of the front wall(42 1) remain on the out- plate(50) of the water-proof and ventilation part(12) and the buoyancy plate(48) is buoyant and rises.

1 The buoyancy plate(C) risen closes the lower part of the inhalation and exhalation entry(46),vhich makes water-proofinj possible as water in the water-incoring room(44) of the water- proof ana-ventilation part(12) can not get into the inhalation exhalation entry.

On the other hand water in the water-incoming rooz(44) 1 1 1 lower the buoyancy plate(48) with the air in the sole of footwear exhaled.

Accordingly, with the air full of the upper part of the water-incoming room(44Y compresses, water in the rooz(44) is i exhaled through the ventilation entry(45) to give the effective water-proofing.

i In Figure 2 as well as is Figure 1, the horseshoe s-shaped i shock absorbing heel material(M) is to be fixed between the upper flap and the lower one(l3M3 ') of the heel part of the out-sole(25) and the water-proof and ventilation part(12) to be fixed in the reception groove of heel part on the reverse side of the out-sole.

1 With the front wall(42 ') facing the front of the footwear sole and the rear wall(42) the Opposite part of it, the ventilation part(47) the ventilation hole(29 ')and the exhaust way(29) are to be connected to the air ventilation room (26) while..the air compression room on the reverse side of the Out-sole(25), air supply hole(30 ") and the air supply ways(30) (30') to the air ventilation room(26) seperately.

In landing, the air in the air compression rooz(16') that is compressed due to the contraction of the shock absorb- ing heel material(A) Of the heel part(32) get into the air ventilation rooz(26) through the air supply hole(3011) and the air supply ways (30) (30 1).

Then, the air in the air ventilation rooz(26) compressed by the sole of foot pass the exhaust way(29) and the ventila- tion hole(29 ') and is exhausted through the inner ventilation part(47) and the external ventilation entry(45) of the water-proof and ventilation part(12).

With the cushioned airbag(23) and the shock absorbing heel material restored the external air is induced into the inside of i the footwear vice versa.

The effect froz the function of the ventilation entry(12) and A 1 0 1 the cushioned airbags(23)(23 ') and the shock absorbing heel mater- ial(A) of the inner sole is same as that in case of sportsshoes of Figure 1.

Especially, the waist part fitted on the out-sole of the 1 footwear having rear heel as in case of boots, military shoes, 1 safety shoes and mountain-clarbing shoes can rezove the factors of problem to shock absorbing due to fitting the steel in texon board.

i i 1 i In addition, the waist part(31) can excercise the function of steel usually fitted at waist portion.
