Definitions

  • the object of the present invention is a metal insole to be applied to working or safety footwear.
  • footwear In order to be in conformity with these norms said footwear must possess specific technical features which vary according to the working environment in which they are to be used: the norms particularly foresee that in environments such as construction sites, shipyards, steelworks or mechanic industries, often characterized by the presence on the workfloor of blunt and sharp objects, such as nails, blades or metal shavings, safety footwear must withstand perforation , that is furnished with a suitable protective metal insole which prevents accidental contact of the foot with said objects.
  • said metal insoles are made up of a flat metal sheet inserted into the plastic sole made of PU, TPU or rubber of the footwear.
  • the main drawback of said existing metal insoles lies in the lack of rigidity in the area between the heel and the arch, that is in the arch of the sole.
  • a 'cambrillon' (French term) is applied, that is, a reinforced element in the area of the arch and positioned in the area situated between the arch of the sole and the base of the heel thus also preventing flattening of the same arch.
  • the aim of the present invention is to eliminate the abovementioned drawbacks by using a metal insole for protective heavy duty industrial footwear which does not require the use of other reinforcing elements, such as a cambrillon.
  • Another important aim is to propose a protective metal insole which may be easily inserted and blocked inside a plastic sole, said plastic sole being of PU, TPU rubber, etc.
  • Yet another aim is to provide a metal insole which guarantees rigidity in the heel-arch of the sole area avoiding torsions illustrated in figures 9 and 10: the reference 4.1 indicates the area near the arch of the sole.
  • the metal insole as claimed in the present invention at the same time solves both the problem of withstanding perforation and that of rigidity in the heel-arch of the sole area, avoiding flattening of the arch support or torsion thereof without applying a reinforcing element .
  • the metal insole has a shape similar to that of a loose sole of a shoe.
  • the invention consists in the application to a metal insole by means of moulding, of special longitudinal ribs 3 which form on the upper surface of the sole grooved ribs 3.1 protruding from the opposite surfaces so as to form the convexities 3.2.
  • the grooved ribs 3.1 of the ribs 3 on the upper surface of the metal insole facilitate attachment of the latter into the sole of the shoe; in fact, the grooved ribs 3.1 fill up with PU, TPU, rubber etc. during realisation of the sole thus rendering impossible to detach once positioned into the said sole.
  • the ribs 3 are constituted only by a perimetral narrow channel which copies the line of the edges of the posterior surface 2 of the metal insole, joining transversally with the rib 3 in the intermediate area 4 of the said insole forming a closed profile.
  • the intermediate surface 2.1 of the insole may however be crossed by one or more than one transversal rib 5 of any shape, size and profile, being able to furnish the insole with the necessary resistance.
  • the posterior part 2 of the insole is in fact crossed longitudinally by three U-shaped rectilinear and parallel ribs, while in the further embodiment as seen in figure 7. the ribs are characterised by a "V" section rather than a "U"-shaped one.
  • the invention in question implies an invention according to Art. 56 of the EPC, since all of the existing protective metal insoles inserted into the rubber, PU, TPU etc. for heavy duty footwear, not being furnished with ribs in the arch support area, do not suggest to a person skilled in the art, the application of ribs in the arch support area, both to stiffen the said area and above all to avoid torsion with respect to the longitudinal axis and transversal axis situated in the area between the heel and the same arch support.
