Definitions

  • the present invention relates to a method for embedding natural or synthetic stones and brilliant-cut glass on a medium made of plastics, preferably made of synthetic resin or acrylic resin or methacrylate or thermoplastic material or polycarbonate or material known by the trademark Naylon, and to a product obtained with such method.
  • thermoplastic and thermosetting resins to manufacture writing instruments, particularly acrylic resins and thermoplastic methacrylate.
  • the presence of stones and glass in a writing object made of thermoplastic acrylic resin requires the presence of a metallic medium, which is inserted beforehand and prepared as a whole with the part or finished product.
  • Another drawback of the background art consists in the high percentage of waste that is inherent in the traditional embedding process, with possible breakage of stones and the need to perform reworking and remaking, which are typical of handicraft manual skills.
  • the aim of the present invention is to solve the above-mentioned technical problems, eliminating the drawbacks of the cited background art, by providing a method that allows to achieve rapidly the embedding of natural or synthetic stones and brilliant-cut glass on a medium made of synthetic resin, acrylic resin, thermoplastic methacrylate, so that the embedding is stable over time and at the same time allows to increase the aesthetic and qualitative value of the product.
  • an object of the invention is to provide a method which does not use adhesives and/or intermediate metallic media.
  • a further object of the invention is to provide a method that allows to achieve the embedding of natural or synthetic stones and brilliant-cut glass on a medium made of synthetic resin, acrylic resin, thermoplastic methacrylate, so that it can be repeated over time and is less subject to the drawbacks that can be observed in the manual work according to the cited background art.
  • Another object is to provide a method that has a considerable reduction of the percentage of waste, with consequent elimination of reworking, remaking and stone breakage.
  • Another object is to provide a method that allows to achieve a higher quality of the resin/stone assembly.
  • Another object is to provide a method that is simple and has low manufacturing costs.
  • a medium is obtained which is made of plastics, preferably synthetic or acrylic resin or methacrylate or thermoplastic material or polycarbonate or material known by the trademark Naylon, which is characterized in that it has, on the outer lateral surface, a plurality of natural or synthetic stones or brilliant-cut glass pieces in which the crown is partially embedded in said lateral surface.
  • the reference numeral 1 designates a medium, such as a writing instrument, constituted for example by a pen and/or a fountain pen composed of a cap 2 and a body 3.
  • the medium 1 is made of plastics, preferably synthetic or acrylic resin or methacrylate or thermoplastic material or polycarbonate or material known by the trademark Naylon, and natural or synthetic stones or brilliant-cut glass pieces 5 are embedded on its lateral surface 4.
  • the method provides for a first step, in which at least one milling of the lateral surface 4 of the medium 1 is performed by means of a milling cutter 6, which has a bit 7 whose dimensions are approximately equal to those of the stone or glass 5 so as to obtain at least one seat 8 which is shaped approximately complementarily with respect to a pavilion 9 and corresponds to the lower half of the stone 5.
  • the method then provides for heating the medium 1 at the at least one seat 8 so as to achieve the partial softening of the material.
  • the temperature can be approximately 80°C.
  • the method provides for picking up the natural or synthetic stone or brilliant-cut glass piece 5, for example by means of appropriately provided tweezers or by means of a tool 10 which has a bit 11 that is adapted to form a vacuum so as to engage the stone 5 at a table 12 (constituted by the upper flat face of the stone) and/or partially at a girdle or crown 13.
  • the pavilion 9 is then arranged in the at least one seat 8 and then an axial force is imparted such as to force the pavilion 9 within the seat 8 so as to obtain a temporary plastic deformation of the seat 8, as shown in Figure 6 , thanks to the temperature to which the medium has been brought.
  • a contraction of the material occurs which entails the formation of a perimetric tab 14, which affects at least partially the girdle or crown 13 of the natural or synthetic stone or brilliant-cut glass 5.
  • a medium made of synthetic or acrylic resin or thermoplastic methacrylate which has, on the outer lateral surface, a plurality of natural or synthetic stones or brilliant-cut glass 5 in which the girdle or crown 13 is partially embedded in said lateral surface, thus protruding from it by a chosen extent.
  • the invention has achieved the intended aim and objects, a method having been devised which allows to obtain rapidly and easily the embedding of natural or synthetic stones or brilliant-cut glass on a medium made of synthetic or acrylic resin or thermoplastic methacrylate, such embedding being stable over time and allowing at the same time to increase the aesthetic and qualitative value of the product.
  • the method does not use adhesives and/or intermediate metallic media, so as to increase the aesthetic finish of the product.
  • the method further can be repeatable over time and is not subject to the drawbacks that can be observed in manual work according to the cited background art, eliminating the percentage of waste, with consequent elimination of reworking, remaking and breakage of stones, obtaining a superior quality of the resin/stone assembly.
  • the localized heating temperature of the medium, as well as the depth H2 of the seat 8 may be the most appropriate as a function of specific requirements; accordingly, the dimension and shape of the perimetric tab 14 also may be the most appropriate as a function of specific requirements and may therefore affect a more or less extensive region of the crown or girdle 13 of the stone 5.
