JQJIIIIIII! INVENTOR BY fa; 44/9 ATTORNEY United States Patent 3,280,484 PREFAERICATED VENTILATED SHOE SOLE Lorenzo Sensi, Via Eremo delle Carceri 5, Assisi, Perugia, Italy Filed Apr. 29, 1965, Ser. No. 451,932 1 Claim. (Cl. 36-3) The object of the present invention is a prefabricated outsole for shoes, especially sandals and slippers, provided with a raised and pierced insole by means of which the underpart of the foot, by remaining in contact with such insole, is raised up from the outsole and is kept ventilated by means of the holes with which the undersole is supplied; the outsole itself being kept at a distance from the insole by means of male and female studs which are kept together by glue.
The result is the achievement of a ventilated outsole which allows the whole foot to breathe freely.
The attached drawings show a preferred form of realising the invention and in them:
FIGS. 1 and 2 show the outsole as seen in plan from above and from the side respectively;
FIGS. 3 and 4 show the insole as seen from above, partly in section, and from the side respectively;
FIGS. 5 and 6 show the prefabricated outsole assembled with the insole as seen from above, partly in section, and from the side respectively.
With reference to the drawings (FIGS. 1 and 2), 1 shows the outsole as finally fitted with its heel 2. At a short distance from its periphery there is a set of equidistantly spaced female studs 3, each having an internal hole 4, designed to receive a corresponding number of male studs 5 which are attached to the periphery of the insole 6, which is provided with air holes 7. The insole may be covered with a layer of material 8, the Whole assembly producing a prefabricated sole of an extremely hygienic type in that the foot is allowed to breathe continuously.
The insole is fixed conveniently to the outsole by means of suitable glue spread over the above-mentioned studs, in such a way as to form a single unit, while the abovementioned studs are thus enabled to act as spacers as is shown in FIG. 6.
The outsole and insole according to the invention may with advantage be produced in various materials, for example plastic or something similar.
It is clear that the arrangement, number and height of the studs may vary within wide limits without affecting their functions as spacers between the outsole and the insole; in the same way the insole may be made out of a cellular material, thus dispensing with the needs for air holes, without in this Way going outside the invention.
What I claim is:
A prefabricated sole for shoes comprising an outsole and an air pervious insole, a set of equidistantly spaced female studs arranged about the periphery of said outsole and spaced a short distance from the edge of the outsole, each of said studs being formed with a central hole therein, a corresponding number of male studs attached to the periphery of said insole and received by said holes in the female studs, and a layer of glue over said studs, whereby to form a solid, single unit of said insole and outsole, and a layer of material covering said insole, said studs serving as spacers, whereby said sole is ventilated by air passing through said air pervious insole and between said studs.
