Definitions

  • the present invention refers to a so-called sanitary shoe and to a related method for making it.
  • the invention refers to a sanitary shoe, made from an appropriate plastic material suitable for withstanding repeated washing and sterilisation treatments, shaped like a boat and defining, in a single piece, an upper and a sole having a heel part.
  • a shoe and in particular a shoe made entirely from plastic material, in order to be of the sanitary type and thus have wide and advantageous use in hospitals, in food companies, in catering establishments like company canteens and the like, must satisfy two requirements:
  • the solution idea forming the basis of the present invention is that of making a recess in the body of a sanitary shoe, and in particular in its sole-heel part, that is insulated and inaccessible from the outside of the shoe, without for this reason reducing the desired characteristics of comfort and structural strength.
  • a sanitary shoe of the type considered previously characterised in that it comprises at least one substantially boxed closed bearing insert, incorporated in said sole-heel part of the shoe and defining a respective recess in it.
  • said insert has a substantially foot- shaped configuration.
  • said foot-shaped boxed closed insert is completely embedded in said sole-heel part of the sanitary shoe.
  • FIG. 1 illustrates a perspective view of a sanitary shoe according to the present invention
  • FIG. 2 illustrates a longitudinal section of the shoe of figure 1;
  • FIGS. 3 and 4 illustrate a detail of fig. 2, in a perspective view and in a view from above respectively, in an open configuration
  • sanitary shoe according to the present invention is globally indicated with 1.
  • the shoe 1 is preferably made through injection moulding of an appropriate plastic material suitable for withstanding repeated washing and sterilisation treatments, possibly in autoclave, like for example an elastomer, preferably a copolymer like styrene-ethylene/butylenes- styrene.
  • the shoe 1 is of the type shaped as a boat 2, comprising, in a single piece, an upper 3 and a sole 4, in which a heel part 5 is defined.
  • Said lightening device essentially comprises a closed boxed bearing insert 10, having predetermined characteristics of rigidity and mechanical strength.
  • Said insert 10 is incorporated in the heel part 5 of the sole 4 and, preferably, it is completely embedded in the plastic material that constitutes said part 5 and, with it, the entire boat 2.
  • the boxed and appropriately stiffened structure of the insert 10 and the chemical-physical characteristics of the predetermined plastic material are such that the presence of said insert 10 in the heel part 5 makes the desired recess 15, without for this reason reducing the characteristics of comfort and structural strength of the sanitary shoe of the present invention.
  • the bearing insert 10 is foot- shaped, having a profile matching that of the heel part 5, in which it is incorporated.
  • said insert 10 comprises a half-shell 13, sealed closed on top by a cover 14, with mutual snap coupling of the respective perimetric edges 23, 23a.
  • the inner wall of the insert 10 is equipped with stiffening ribs
  • the shoe 1 comprises a sock 30, which constitutes an inner coating of the upper 3 and of the sole 4, to which it is fixed with conventional means and techniques.
  • Said sock is preferably made from elasticised cotton or else nylon, or lycra-nylon- lycra, or other similar materials suitable for making the shoe of the present invention particularly comfortable and easy to put on.
  • the upper 3 can have, near to the join of the sole 4, a plurality of aeration holes 27, as well as sculpted designs 31 in the visible surface.
  • a substantially gutter-shaped appendix (not represented) can be foreseen in said upper 3 to avoid the dripping of liquids in the aeration holes 27.
  • the sole 4 can be suitably equipped with an anti-slip sculpting.
  • a soft coating can be applied in the upper 3, at the opening for the insertion of the foot, to give greater comfort during use.
  • the plastic material with which the shoe 1 is made can be transparent to make a possible design motif or similar decoration of the sock 30 visible.
  • the injection moulding technique of an appropriate and predetermined plastic material for example polypropylene carbonate, polybutadiene styrene and similar.
  • moulding by such a technique is researched and designed to simultaneously obtain, at each moulding, the half-shell 13 and cover 14 parts, with the respective stiffening ribs 18, connected together, on opposite edges, by small bridges 35, sized to allow sealed snap coupling between cover 14 and half- shell 13 when moulding is complete.
  • the boxed insert 10 thus obtained is correctly position in a mould arranged for the formation of the boat2 of the shoe of the present invention.
  • said insert is equipped with appendices also known as "bearing wings" 20, 21, 22, projecting from the perimetric edge 23 thereof, in particular of the half- shell part 13 and with a plurality of spacer pegs 37.
  • the mould is closed and the predetermined plastic material is injected into it, obtaining the boat (upper, sole and heel), in the heel of which the insert 10 is incorporated.
  • the position of the insert 10 in the aforementioned mould is selected so that it is completely embedded in the respective sole-heel 5.
