Definitions

  • the present invention relates to overheating articles such as kicks or booties intended to be covered over their shoes by persons having to enter or stay in clean and sterile rooms, in particular in surgical operating rooms, laboratories and workshops for the manufacture of electronic components and equipment.
  • overheating articles must be capable of being cleaned and sterilized with a view to their reuse and must consequently be able to withstand repeated washing with detergents and / or solvents, in particular fluorinated solvents, at high temperatures, in practice above 150 °, for autoclave passage, as well as to radiation such as ⁇ or 2i radiation
  • overheating articles comprising a textile upper assembled, by hot gluing, to a rubber or similar sole, in particular of polyurethane comprising a shoe extended upwards by a substantially vertical peripheral edge.
  • the polyurethane sole is produced by injection molding.
  • the superheating articles thus produced have, by the nature of the material of the sole, of its manufacturing process as well as of its assembly with the textile upper, various notable drawbacks.
  • the sole made of polyurethane is not antistatic, which prevents the use of the over-shoe article in premises where static electricity phenomena are likely to occur such as, for example, micro laboratories. -electronic.
  • the sole is slippery on wet ground and offers relatively low resistance to abrasion and cuts.
  • the method of manufacturing the sole by injection molding also has the disadvantage of using multi-part molds which are reflected on the sole by zones, corresponding to the joint planes of the mold, having asperities increasing the risk of 'abrasion.
  • the present invention proposes to produce an overheating article such as a boot or a bootie which, while having the qualities allowing it to be reused after cleaning and / or sterilization, avoids the drawbacks mentioned above.
  • the article of footwear according to the invention is essentially characterized in that the sole is made of nitrile rubber, in one piece by compression molding, and is assembled from separable from the textile upper, preferably in the vicinity of the upper part of its peripheral edge.
  • the upper and the sole are assembled by sewing inside a peripheral groove formed in the outer wall of the peripheral edge of the sole.
  • the nitrile rubber used according to the present invention for the production of the sole is a non-halogenated nitrile rubber added with plasticizers.
  • the material constituting the sole can be made electrically conductive, in particular by adding carbon black. It is thus possible to give the sole a resistivity of for example 7.4 M fi / cm2 measured according to DIN 4843 standard which allows the footwear according to the invention to be used in workshops or laboratories, for example in microelectronics where the floor is made conductive of electricity.
  • the overheating boot comprises a sole 1 and a textile rod, thin and flexible, for example made of polyester, which is tubular in shape and comprises, at the front part, a closure means such as a zipper 3a, in the upper part of the means such as a tab 3b to be fixed by snaps tending to narrow the entry of the rod 2 once the boot is in place.
  • a closure means such as a zipper 3a
  • a tab 3b to be fixed by snaps tending to narrow the entry of the rod 2 once the boot is in place.
  • the retention of the boot is ensured by a strap 3c provided with a locking member, in particular with 3d snap.
  • the sole 1 compression molded in a single block, made of non-halogenated nitrile rubber, by heating at a temperature of 162 ° C for about 10 minutes has a thickness of 2.5 mm and a substantially "anatomical" shape in that well similar for both feet, it roughly follows the shape of users' shoes.
  • This sole the outer surface of which is grained, consists of a shoe 4 secured to an edge 5 which is provided at its upper part with a peripheral groove 6.
  • the assembly of the upper 2 to the sole 1 is done by sewing 7 a hem 8 internally to the sole 1, stitching made at the bottom of the groove 6.
