Definitions

  • the present invention relates to a method for producing a protective element for sports shoes and/or items of clothing and to the product thus obtained.
  • Said conventional rigid plates are not free from drawbacks: the pieces of resin-impregnated fiber that must be placed in the autoclave in fact require rather long production times to complete the process for the agglomeration of all the materials, with a high cost of production facilities.
  • protective elements are conventionally produced by using appropriate molds for injecting thermoplastic material; said protective elements are then associated by sewing with the shoe upper or item of clothing in the particular regions to be protected.
  • said plates in fact have high costs, caused by the particular machines required to produce them, and said plates furthermore have limited mechanical resistance to impacts.
  • a principal aim of the present invention is therefore to solve the described technical problems, eliminating the drawbacks of the cited prior art, by providing a method that allows to produce boots, motorcycle shoes, shoe soles, and items of clothing, such as gloves, jackets, jerseys, pants, provided with protective elements that have excellent resistance to impacts and abrasion, said elements being obtained with low production costs.
  • an important object is to provide a protective element that has low weight and considerable strength and allows to produce a shoe that is reliable and safe during sports practice.
  • Another object is to provide a protective element that can be used as a protection in items of clothing particularly for motorcycling, such as gloves, jackets, jerseys, and pants.
  • Another important object is to provide a protective element that allows easy and quick application to the shoe upper or to an item of clothing and has good mechanical characteristics, or allows to produce soles for motocross, mountain biking, and cycling shoes.
  • Another object is to provide a protective element that can be obtained with conventional machines and equipment.
  • the reference numeral 1 designates a sports shoe, such as a motocross boot.
  • Said shoe 1 has an upper 2 that wraps around the foot and the lower part of the user's leg and below which a sole 3 is associated.
  • the shoe 1 can have a plurality of aesthetic solutions: thus, for example, in the particular embodiment that is shown, the shoe 1 has, at the first foot instep region 4 and at the second toe region 5, respectively a first part 6a and a second part 6b made of foamed material that is adapted to absorb impacts, said parts being sewn and/or glued to the upper 2.
  • the upper 2 can be closed by means of conventional systems, such as: at the third heel region 8, by partially overlapping two flaps of said upper 2, fastened by means of hooks or levers, or by using one or more layers of a material known by the trade-name Velcro, or by providing the upper 2 with particular elastic parts.
  • the upper 2 has, at the front and at the fourth tibial region 10 and above the first region 4 up to the upper perimetric border 11 of said upper 2, an element 12 that is formed monolithically and is adapted to absorb any impacts.
  • the element 12 is provided according to the claimed method by using thermoformation technology alone: said product is obtained, in a first embodiment, in a single step for the thermoformation of at least one first layer 15 of a material adapted to absorb impacts and constituted by a thermoformable composite material that includes thermosetting or thermoplastic materials, such as a thermoformable impregnated fabric, as for example a fabric impregnated with a epoxy resin.
  • thermoformation technology alone: said product is obtained, in a first embodiment, in a single step for the thermoformation of at least one first layer 15 of a material adapted to absorb impacts and constituted by a thermoformable composite material that includes thermosetting or thermoplastic materials, such as a thermoformable impregnated fabric, as for example a fabric impregnated with a epoxy resin.
  • Said material has the characteristics of the kind provided by the product marketed by Dupont under the trademark Tepex.
  • the dimensions of the element 12 may be any according to the specific requirements of the user, and the arrangement may also be the most appropriate according to the requirements of the sports practice; likewise, it is possible to obtain soles for sports shoes.
  • the element 12 can be produced by overlapping a plurality of layers 15 of material, optionally in a crossply fashion in order to increase final strength; once said layers have been arranged adjacent to each other, the element 12 is given the desired shape exclusively by thermoformation.
  • the element 12 thus produced is then associated, for example by sewing, laterally or below the upper 2, or with a part of an item of clothing such as for example a glove, a jersey, a pair of pants, which can require particularly rigid protective regions.
  • the protective element thus conceived has achieved the intended aim and objects, is obtained with low production costs, and can be associated with the shoe or item of clothing in a short time; the invention has excellent impact- and abrasion-resistance characteristics and is obtained by means of a single thermoformation step and therefore with low production costs.
  • Figures 3 and 4 illustrate a second embodiment for an element 112 that is formed monolithically in a one-piece by means of a preliminary adjacent arrangement and a subsequent single thermoforming step involving at least one first layer 115 of a material adapted to absorb impacts, constituted by a thermoformable composite material that includes thermosetting or thermoplastic materials, such as a thermoformable impregnated fabric, and of a part of an upper 102.
  • a lining 109 can be sewn to said element 112, thus obtaining the complete upper 102.
  • Figures 5 and 6 illustrate a third embodiment for an element 212 that is formed monolithically by means of a single step for the thermoformation of a part of a lining 209, of at least one first layer 215 of a material adapted to absorb impacts and constituted by a thermoformable composite material that includes thermosetting or thermoplastic materials, such as a thermoformable impregnated material, and of an upper or part of an item of clothing 202 arranged adjacent to each other beforehand.
  • Figures 7 and 8 illustrate a fourth embodiment of an element 312 that is formed monolithically by means of a single step for the thermoformation of a part of a lining 309, of at least one first layer 315 of a material adapted to absorb impacts and constituted by a thermoformable composite material that includes thermosetting or thermoplastic materials, such as a thermoformable impregnated material, and of a part of an upper 302; all of said components are arranged adjacent to each other beforehand, with the interposition, between the first layer 315 and the lining 309, of a second layer 316 of a material adapted to contrast impacts, such as for example a padding.
  • Figures 9 and 10 illustrate a fifth embodiment, in which the element 412, formed monolithically, has a shape that is obtained by arranging adjacent to each other, before the single thermoforming step, a part of a lining 409, a second layer 416 of a material adapted to contrast impacts, and at least one first exposed layer 415 of a material adapted to absorb impacts, constituted by a thermoformable composite material that includes thermosetting or thermoplastic materials, such as a thermoformable impregnated fabric.
  • the element 412 is then perimetrically associated, for example by sewing, with a part of the upper or with a part of an item of clothing.
  • Figures 11 and 12 illustrate a sixth embodiment of an element 512 that is formed monolithically by means of a single step for the thermoformation of a part of a lining 509 that is arranged adjacent to at least one first layer 515 of a material adapted to absorb impacts and constituted by a thermoformable composite material that includes thermosetting or thermoplastic materials, such as a thermoformable impregnated fabric, to which one or more optionally colored external films 517 are arranged adjacent beforehand.
  • a thermoformable composite material that includes thermosetting or thermoplastic materials, such as a thermoformable impregnated fabric, to which one or more optionally colored external films 517 are arranged adjacent beforehand.
  • Said films 517 have different shapes whereon lettering and/or designs can be provided by thermoforming.
  • each element may of course be the most appropriate according to the specific requirements of the shoe and/or of the item of clothing.
