Definitions

  • the present invention belongs to the footwear technological sector and refers, more specifically, to a new arrangement in the footwear insole structure.
  • the insole has an injected part essentially with reinforced support area, reinforcement ribs, central rib, transversal ribs and a front part that is joined to the injected part.
  • REPLACEMENT SHEETS (RULE 26) high heels are typically worn with heights ranging from 1 1 ⁇ 2 inch (4 cm) kitten heels to 4 inch (10 cm) or more silver half heels. Extreme high-heeled shoes, such as those over 5 inches (13 cm), are usually worn for aesthetic reasons only and are not considered practical. High heels are used for work and formal occasions normally, while there are more common styles to wear in other situations. High heels have seen significant controversy in the medical field lately, with podiatrists and orthopedists indicating that many patients have severe problems with their feet, heels, ankles, knees or spine; however, this does not mean that all women wearing high heels will experience such complications.
  • the shoes started to better accommodate the curvature of the soles of the feet according to the height of the heels, allowing a wide proliferation of heels culminating in the last century in the creation of the Stiletto, by many credited to Roger Viviee, but which in fact would be a creation of the Italians Dal C ⁇ and Albanese, who created a sandal for the night, with two tiny straps and a low heel under the arch of the foot.
  • Steel souls for the footwear sector are fundamental structural pieces in high-heeled shoes, be they medium-low or high, in addition to the many platforms. They are produced by steel fillets as the name already refers, next to the mounting insole that has the purpose of supporting the arch of the foot, and the necessary balance for the user of these shoes, where it extends from the sole of the foot to the heel , being fixed to the heel by screws or nails.
  • the steel core is usually surrounded by a resistant cellulose called a plantex, located between the mounting insole and the reinforcement of the insole, there are cases where the steel core is wrapped not in cellulose, but in PVC or ABS (or similar) , which can be injected on the steel core or mounted on it as in the traditional cellulose insole.
  • the technology described in the document in question comprises a high-heeled shoe sole comprised of a plate, a fixing device and a reinforcement piece; where this fixture is embedded in the plate space and the reinforcement piece is joined to the fixture.
  • the solution aims to obtain a safer structure as to the user's torsions and flexions, as well as other efforts; however, this is achieved by means of a joined fixing device and reinforcement piece; however, it does not take advantage of rigidly calculated ribs to obtain comfort and safety, moreover, by means of a single injected part as of the present application of invention.
  • This patent document more strictly, refers to the material that is used at the base of the shoe, similar to that of the present product “[...] and a main body in which a groove is formed so that the arch and heel of foot can be settled and the rear part thereof is made of one among glass fiber, fiber reinforced plastics, and polypropylene ''.
  • the patent document below uses materials similar to the present application, it does not provide for the rib technology developed and demonstrated by means of structural calculations, nor is it injected into one piece.
  • the present invention proposes a new arrangement applied to footwear insoles with a set of ribs and having a thickness variability that form reinforced areas for the production of this piece.
  • the product such as the bone structure of our body and the shape of the whales' tail, natural designs that present exceptional resistance, together with weight reduction.
  • the proposed invention in a functional and modern way provides users with comfort and safety through an innovative arrangement. Therefore, from the use of this element in the manufacture of footwear, especially high-heeled shoes, the benefit is evident in terms of twists and other unexpected efforts, and also, over time, health complications with regard mainly to members lower parts of the human body.
  • the present invention proposes a versatile alternative for the production of midsoles, using raw materials such as polypropylene and fiberglass ranging from 40 to 60%, but more specifically 50%; however, there may be the application of other materials, but the prices for the acquisition of these may be higher. These raw materials together, provide the piece with high resistance to traction, flexion and impact, allowing ample flexibility, with the molding of complex pieces, large or small, without seams and with great functional and aesthetic value. Therefore, the injection process that is commonly known and used in the footwear sector for the manufacture of parts plastic, proposes flexibility, productivity, dimensional and surface quality for the sole parts.
  • an insole for footwear especially high-heeled shoes, was developed with ribs precisely distributed over the surface of the injected part, together with support and reinforcement areas with variability in thicknesses .
  • ribs are spread over the bottom surface of the insole, with reinforcement ribs, transversal ribs, a central rib together in the piece, of rigidly calculated thicknesses, to provide structure, flexibility and security in what concerns the element. refers to obtaining resistance to normal and abnormal efforts.
  • the footwear production process benefits from a circular economy of recycling and reverse logistics by having materials that can be recycled, and in addition, leads a reduction in production steps.
  • it provides, by means of just one piece, considerable advantages in relation to the reduction of the weight of the shoes and, consequently, the effort required for their use, directly impacting the comfort of the shoes.
  • the solution proposed in the present patent application avoids discomfort generated by the steel souls in metal detectors, such as in airports, creating discomfort for users when they pass through the scanner and are forced to remove their shoes, since the metal souls activate the alarms.
  • the mounting insole also admits that shoes can be wet, facilitating cleaning and drying more quickly, since the front of the insoles is currently produced in cardboard.
