| 1. | System for making atossic the shoe bottoms, characterized bv the fact that on a generic bottom (1) of a shoe, a contact and leaning base for the foot with a sole conformation (2) in atossic material, with closed cellule, is employed which thus operates as insulating film. This said insulating film (2) , with underlying damping part (3) , is conformed with furrows (4 and 5) which determine two clos¬ ed perimetral lines, of which one (4) corresponding to the toes and the other (5) to the remaininα part of the foot, with n the furrow ing forms (4 .and 5) , parallel furrow systems (6 and 7) are foreseen which determine intermediate wedσes (8 and 9) acting with selfmas¬ saging effect on the foot base during the movement. |
| 2. | System for making atossic the shoe bottoms, as per claim 1, cha racterized by the fact that the insulating film (2) can be fitted solidarilv leant or otherwise integrated with the bottom structure. |
| 3. | System for making atossic the shoe bottoms, as per claim 1, cha¬ racterized by the fact that the isolating film (2) can be foreseen on a damping support, thus determininα a ccmfortable leaning base for the foot, apart frcm the stiffness of the bottom. |
The invention refers to a new conceipt which prevents the af lux of the toxines ccming frcm the shoe bottom due to the arising pressu¬ res.
The present shoe bottcm parts are made in leather, tissues, wood es_ sences and petrol derivates, such as nulyurethan, FVC, and others, all materials with open cellule allowing toxine appearing. In parti cular, the necessity of employinσ glues for assemblinσ the cc-moosi- tion plate of the bottcm gives rise to the toxine appearing even with a poisonless base conformation, such as wood essences. In the polyurethan and other petrol extract bottoms for shoes, which have a microporous conformation and are toxic, a high afflux of toxines is noted. More generically the toxine afflux frcm working materials and products to the leaninα base of the foot, in the nresent bottom for shoes, causes defilsnent and skin irratation on the foot with consequent abundant perspiration and issue of bad smells. Moreover the toxine flow is transmitted rom the foot to the varan thus lead-
ing to the sheo deterioration in its whole.
The invention allows the solution of the nroblem bv e nloving an isolatinσ structure interposed between the foot base and the shoe bottom. Substantially, on the upper bottom part, a contact and leaning base for the foot in atossic material with closed cellule is e ploved which, in this way, acts as an isolating film. The nro ceeding can be carried out by -emploving films in plastic materials which are now currently employed in the confection of foot products, pharmacy, surgical materials and others.
In a version, the isolating film, will be fitted solidarilv or o- therwise integrated with the bottom structure. In another version, the insulating film, either supnorted or not, will be leant on the bottcm upper part. In a further version, this insulating film is foreseen on a ciamping support, what determins a cσ fortable lean- ing base for the foot, even with a stiff ground.
An execution form is illustrated in a mere indicative wav and, the¬ refore, as such not liritinα the proceeding, in the drawings of ta¬ ble 1 , wh^sre fig. 1 is the view from above o the insulating form carriped out in a damping conformation. Fig. 2 is the transversal section of the same isolating form to point out the cσmnonents. Fiα. 3 is the view of the shoe bottom with an insulating film solidarilv fitted according to the invention.
The version employs, on a p sneric ground 1 , the isolatinσ film 2 ■executed in atossic material with underlving part 3. The film is formed with furrows 4 and 5 which determine two closed perimetric- al figure lines, of which 4 in correspondence with the toes and 5 of the remaining foot part. Within the furrow forms 4 and 5, the parallel furrow svstems 6 and 7 are foreseen determining intermedia
• te weαges o ana y wnicn, during the movement, operate with a self- massaging effect of the foot base. The leaninα sole can be freelv put on the shoe bottom or fitted in another way.
The execution particulars, the materials and other else can be fo¬ reseen in different way?
