Definitions

  • the present invention relates to an antistatic sole which can be used on any type of shoe for discharging, to earth, electrostatic energy which may build up on persons.
  • shoes In order to prevent persons being subjected to these unpleasant shocks, shoes have been developed with a sole which allows discharging, to earth, of the electrostatic charge owing to the presence of a conducting element mounted thereon and making contact on the one hand with the feet and on the other hand with the ground.
  • this conducting element consists of a metal plate which is inserted in the inner sole of the shoe so as to be always in contact with the foot (generally with the heel) and is connected to a number of metal terminals passing through the sole and making contact with the ground by means of free ends.
  • the metal terminals which project from the bottom surface of the sole in order to make contact with the ground may scratch floors (in particular wooden parquets) or may get caught in the pile of carpets, thereby making it impossible to wear these shoes in many environments.
  • the metal terminals are subject to a degree of wear which is different from that of both rubber and leather soles and therefore may not be able to ensure any longer contact with the ground.
  • the plate and the metal terminals should be made of copper, two further drawbacks arise.
  • the first one relates to the fact that copper oxidises fairly quickly and therefore adversely affects the electrical connections with the ground and the foot.
  • the second drawback relates to the fact that the copper oxides, in addition to soiling both the foot via the plate and the floor via the terminals, constitute a notorious health hazard. Therefore it is considered inadvisable to use them where there is contact with the skin or in any case in applications where there is the possibility of them coming into contact with persons.
  • the main object of the present invention is therefore that of overcoming the drawbacks associated with soles of the known type by providing an antistatic sole for shoes which allows discharging, to earth, of the electrostatic charge which has built up on persons, in a reliable and entirely safe manner and without damaging floors or carpets.
  • a further object of the present invention is that of providing an antistatic sole which is constructionally simple and operationally entirely reliable.
  • the antistatic sole for shoes in question which is characterized essentially by the fact that it comprises a conducting element which is mounted on an insole, a terminal which is connected to the conducting element and passes through the sole, making contact with the ground by means of its free ends and consisting of a carbon fibre which, during normal use of the shoe, is subject to substantially the same degree of wear as the sole.
  • the conducting element consists of a carbon-fibre fabric which is wound in bundle form on a portion of the insole.
  • Figure 1 shows schematically an exploded perspective view of the antistatic sole according to the present invention.
  • 1 denotes in its entirety the antistatic sole according to the present invention. More in detail, it is composed of a sole 2 and an insole assembly 3 consisting in turn of an inner sole 4 and an arch support 5. Functionally speaking, the insole assembly 3 is connected on top of the sole 2, while the arch support 5 is mounted on the rear part of the inner sole 4.
  • the inner sole 4 has, formed on its surface, two incisions 6 by means of which a carbon-fibre meshwork is wound in the manner of a bundle so as to form a conducting element 7.
  • This bundle is fixed to the inner sole 4 by means of stitches 15.
  • an opening 8 is formed on the arch support 5 so as to allow the conducting element 7 itself to emerge from the upper surface 9 of the arch support 5.
  • the conducting element 7 extends inside a portion of the insole 3 opposite the rear part of the sole 1. Obviously it is possible to envisage that this conducting element 7 occupies a much larger zone of the insole 3 without thereby departing from the protective scope of the present patent.
  • the conducting element 7 has, connected underneath it, a terminal 10 (by means of one end 13) consisting of a carbon-fibre fabric braiding.
  • this braiding may be provided internally with a core of reinforcing material.
  • the terminal 10 extends through the sole 2 and branches out into a plurality of peripheral sections 11 making contact with the ground by means of corresponding free ends 12.
  • the conducting element 7 and the terminal 10 may be incorporated inside the sole 2 during the manufacturing process which is performed by means of casting in a mould.
  • the antistatic sole 1 therefore allows a constant electrical connection to be maintained between the foot of the person wearing the shoe and the ground. This connection is ensured by the conducting element 7 which is in contact with the heel of the foot and by the conductor terminal 10 which is connected at one end 13 to the conducting element 7 and at the free end 12 to the ground.
