Definitions

  • the present invention relates to a footwear, where footwear means, for instance, but without the list being exhaustive: shoes, sandals, boots, and the like, hereinafter indicated with the generic term "footwear".
  • footwear means, for instance, but without the list being exhaustive: shoes, sandals, boots, and the like, hereinafter indicated with the generic term "footwear”.
  • footwear The following description will specifically refer to shoes, being it understood that it is not intended to limit the scope of the possible applications of the invention.
  • a traditional footwear of the known type is made of several components assembled together in one or more phases by means of seams or glues.
  • Each model of footwear may have different components based on its features, however the main components generally are: upper, assembly insole, sole, and heel.
  • the upper is the upper part of the footwear, which is joined to the assembly insole by seam or glue; the upper is generally formed by a great number of components of different materials sewn or glued together: the most used materials are leather, plastic, or fabric.
  • the sole is the lower part of the footwear in direct contact with the ground, intended to protect the plantar surface.
  • the upper and the assembly insole are generally joined to the sole through seams or glue.
  • the heal is applied to the rear part and may also be an integral part of the sole.
  • the main purpose of the present invention is to provide a new type of footwear able to solve the above drawbacks.
  • the main purpose of the present invention is to provide a disassemblable and recyclable footwear made of components designed to be easily separated and recycled, whose production may be inserted into the traditional production cycle.
  • all of the components which it is made up of are reduced in number and optimized to be assembled without the use of glues or seams between components of different materials, but through a system of interlocking joints and twines that speeds up and facilitates the assembly and subsequent disassembly to be recycled in an optimal manner.
  • component "A” may be made of pieces of fabric of material “B” sewn together through a thread of material "B", since the same material composition of the pieces of fabric and thread does not affect the recyclability of the entire component "A”.
  • Fig. 1 the main components that when assembled make up the entire shoe are represented, in particular:
  • the components are three, but they can also be in smaller or larger numbers.
  • the external structure (1) is the outermost component that embeds the sock-liner (2) and the hygienic insole (3) therein, it protects the foot from external shocks and gives robustness to the entire shoe.
  • the sock-liner (2) wraps the foot supporting it in every movement and creates a softer layer between foot and external structure (1).
  • the hygienic insole (3) gives greater comfort and creates a further layer between the external structure (1) and the most stressed area of the foot, the sole of the foot; it can also be easily removed to clean and sanitize the shoe.
  • the sock-liner (2) is made of the upper (2b) and the assembly insole (2c) sewn together. On the lower part of the assembly insole (2c) the lace (2a) is sewn. (See Fig. 1 and Fig. 3 )
  • the sock-liner (2) is inserted inside the external structure (1), which has therein a cavity (1a) that blocks the entire perimeter of the assembly insole (2c) along the seam with the upper (2b). This allows creating a solid union between external structure (1) and sock-liner (2). (See Fig. 3 )
  • each component is made of has a key role since it determines the optimal recycling or not of the component and must adequately fulfill its function. Only by way of example and without limitation of the scope of the possible materials usable in the present invention, the materials may be:
  • the separation of the components is easy and quick: extracting the hygienic insole (3), cutting or unsewing the lace (2a) in the point of the seam (2e) and extracting the sock-liner (2) from the external structure (1) taking care to leave the assembly insole (2c) from the cavity (1a): the lace released from the seam at the point (2e) which held it in place, will slide out as one with the sock-liner (2).
  • All of the components - external structure (1), sock-liner (2) and hygienic insole (3) - thus separated, may be recycled based on their material composition.
