Definitions

  • the present invention refers to an anti-static sole assembly for footwear, the purpose of which is to assist and facilitate the discharge of static electricity which has built up in the wearer for whatever reason.
  • the discharge can be sufficient to produce a spark when contact is made with a conductive body with which there is a significant potential difference, at which time a most unpleasant sensation results for the wearer.
  • the sole assembly of the invention has the advantage of favouring the discharge of electricity which it conducts or shunts to ground, avoiding thereby the disagreeable effects produced by the electrical charges mentioned.
  • walking shoes, sports shoes and any other type of footwear all incorporate sole assemblies which have different structures that, in general, are not specifically designed to suppress the unpleasant static electricity charges that at times build up on the feet of the wearer.
  • composition of some soles does incorporate a means for removing these static charges which is often inadequate, for which reason their suppression is only partial.
  • the invention proposes an anti-static sole for footwear which facilitates the discharge of static electricity when this has built up on the feet of the wearer for whatever reason.
  • the conductive body is in direct contact with the outsole and with the foot of the wearer for the purpose of facilitating the conduction of static electrical charges to ground.
  • the conductive body includes on its top side small nodules which traverse the insole and, consequently, said nodules are in direct contact with the foot of the wearer, as well as the top side of the insole.
  • the conductive body is also in close contact with the external body or outsole in order to facilitate the flow of static electricity into said outsole and from there to ground; said outsole clearly also having conductive properties.
  • the sole can also have any other structure which facilitates the discharge of static electricity which has built up on the foot of the wearer.
  • the intervening body includes a conductive body which serves to facilitate the flow of static electricity which has built up on the feet of the wearer to ground.
  • the novelty of the invention is essentially centred in advantageous means for conducting static electricity discharges from the foot of the wearer into the outsole or external body which is in contact with the ground.
  • the anti-static sole assembly is determined from a structure which comprises, in principle, a main interposed piece 1, an upper insole 2 and an outsole or external piece 3 which is in contact with the ground.
  • the main piece 1 consists of a perimetric frame 4 and a conductive filling 5 which, in principle, is in close contact with the outsole or external piece 3.
  • the insole 2 is attached to the upper side of the main piece 1, at the same time as means have been provided for contact between the foot of the wearer and the conductive filling 5 in order to permit discharging of static electricity from the wearer's feet, the insole 2 being affected by said means.
  • the conductive filling 5 together with the perimetric frame 4 of the main piece 1 are subjected to a vulcanising process for shaping purposes.
  • the means of contact has various structural embodiments which are described below.
  • the conductive filling 5 incorporates small modules 6 distributed over its upper surface, said nodules also fitting into small complementary through-holes 7 made in the insole 2. In this manner the feet of the wearer come into direct contact with these small nodules 6 which form part of the conductive filling 5 in order to shunt the electrical charges from the feet of the wearer to ground.
  • the means of contact comprises one or more seams stitched with wire conductor 8 which traverses the insole 2, as well as the conductive filling 5 and the perimetric frame 4, these last two items forming the main piece 1.
  • the feet are in contact with said wire 8 which serves to conduct the discharged static electricity to the conductive filling 5 and the latter, to the sole 3 in contact with the ground, which is the final recipient of the discharged electricity.
  • the means of contact comprises a wire conductor 9 which only traverses the insole 2, at the same times as it makes connection with the conductive material or filling 5.
  • the means of contact comprises inserts 10 of conductive material which are in direct contact with the filling 5 of the main piece 1.
  • the insole 2 one or more recesses 11 are implemented, said recesses being occupied by the aforementioned inserts 10 joined to the insole 2 by means of stitching or whatever other means.
  • the fabric constituting the upper insole 2 incorporates conductive compounds 12 which have been incorporated during the manufacturing process of said insole 2.
  • the conductive filling of the main piece 1 shall be preferentially distributed as various small bodies, cylindrical in shape or otherwise, which are in direct contact with the underside of the insole 2 and with the outsole or external piece 3.
  • a thin laminar sheet 14 is attached to the lower face of the main piece 1, said laminar sheet 14 being interrupted by the lower extremities of the cylindrical bodies 13 which are in direct contact with the outsole or external piece 3.
  • this outsole 3 also has conductive properties, since it is this element which finally transmits the static electricity charges on the feet of the wearer to ground.
