Abstract

On a generic bottom (1), the system foresees a base of contact for the foot leaning, insole-shaped and carried out in poisonless waterproof film (2). This interposition form (2) with furrows (4 and 5) prevents the toxines coming from the bottom from flowing to the foot, foresees a deadening part (3) on the underlying position, and is fitted with intermediate wedges (8 and 9) with self-massaging effect on the foot during the movement.

Description

"System for making atossic the shoe bottoms".

The invention refers to a new conceipt which prevents the afflux of the toxines coming from the shoe bottom due to the arising pressures.

The present shoe bottom parts are made in leather, tissues, wood es sences and petrol derivates, such as pulyurethan, PVC, and others, all materials with open cellule allowing toxine appearing. In particular, the necessity of employing glues for assembling the composition plate of the bottom 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 from working materials and products to the leaning base of the foot, in the present bottom for shoes, causes defilement and skin irratation on the foot with consequent abundant perspiration and issue of bad smells. Moreover the toxine flow is transmitted from the foot to the vamp thus lead ing to the sheo deterioration in its whole.

The invention allows the solution of the problem by employing an isolating 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 employed which, in this way, acts as an isolating film. The proceeding can be carried out by employing 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 solidarily or otherwise integrated with the bottom structure. In another version, the insulating film, either supported or not, will be leant on the bottom upper part. In a further version, this insulating film is foreseen on a damping support, what determins a comfortable leaning base for the foot, even with a stiff ground.

An execution form is illustrated in a mere indicative way and, therefore, as such not limiting the proceeding, in the drawings of table 1 , where fig. 1 is the view from above of the insulating form carried out in a damping conformation. Fig. 2 is the transversal section of the same isolating form to point out the components. Fig. 3 is the view of the shoe bottom with an insulating film solidarily fitted according to the invention.

The version employs, on a generic ground 1, the isolating film 2 executed in atossic material with underlying part 3. The film is formed with furrows 4 and 5 which determine two closed perimetrical 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 systems 6 and 7 are foreseen determining intermedia te wedges 8 ana 9 which, during the movement, operate with a self-massaging effect of the foot base. The leaning sole can be freelv put on the shoe bottom or fitted in another way.

The execution particulars, the materials and other else can be foreseen in different way?

Claims

Claims.

1) System for making atossic the shoe bottoms, characterized by 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 closed perimetral lines, of which one (4) corresponding to the toes and the other (5) to the remaining part of the foot, within the furrowing forms (4 and 5), parallel furrow systems (6 and 7) are foreseen which determine intermediate wedσes (8 and 9) acting with self-massaging effect on the foot base during the movement.

2) System for making atossic the shoe bottoms, as per claim 1, characterized by the fact that the insulating film (2) can be fitted solidarily leant or otherwise integrated with the bottom structure.

3) System for making atossic the shoe bottoms, as per claim 1, characterized by the fact that the isolating film (2) can be foreseen on a damping support, thus determining a comfortable leaning base for the foot, apart frcm the stiffness of the bottom.
