Description

  The present invention relates to a rivet decorated with a jewel, a simulated jewel, or the like, and a method for manufacturing the rivet.

  A rivet is generally used to fasten two or more sheet-like objects or to decorate an attachment object. As an example of a decorative rivet for clothing, an invention such as the following Patent Document 1 is known.

According to this prior art, a decorative body is made of an arbitrary material in advance, and the decorative body and a polyacetal resin-made rivet body are integrally molded by using the decorative body as a part of a mold. A rivet member for clothing comprising a rivet body is formed. As the decorative body, it is described that thermosetting resins such as polyester, metal, glass, natural stone, natural wood, shells, etc. can be used in addition to thermoplastic resins such as nylon and ABS resin.
Japanese Patent Laid-Open No. 10-215917

  In this prior art, there is no problem until the rivet is manufactured, but there may be a problem when the rivet is driven into an object such as clothes or caulked using a hitting machine. This is because the decorative body is a glass processed product cut like shellfish or jewels, but it is strongly pressed by the metal nails and edges, so that the decorative body is chipped or cracked when force is applied. It is because it is easy to do. For this reason, it is difficult to automate the attachment of decorative rivets to clothes or the like.

  It is an object of the present invention to provide a decorative rivet that is less likely to be damaged even when attached to an object, even when a driving machine is used.

  The decorative rivet of the present invention is provided with a surface material having a through hole and an edge around the through hole, a decorative body visible from the through hole, a center seat that supports the decorative body, and a leg portion that supports the central seat. A base material, a backing material that is caulked to the base from the back of the object to be mounted, and the decorative body is fixed by being sandwiched between an edge of the surface material and the center seat, A first step portion is formed on the inner seat, and a second step portion is formed on the center seat. The first step portion and the second step portion are in contact with each other.

  In the method of the present invention, a base and a decorative body are placed on a base, and the surface material is covered so that the decorative body can be seen from the through-hole of the surface material. In the method for manufacturing a decorative rivet to be squeezed, a first step portion is formed on the surface material, a second step portion is formed on the center seat, and the decorative body is squeezed when the parts are caulked by a driving machine. The first step portion and the second step portion are in contact with each other before the pressing force of the hitting machine is applied.

  According to the present invention, when the various parts are caulked in the hitting machine, the first step portion and the second step portion come into contact with each other before the applied pressure of the hitting machine is applied to the decorative body. A strong pressing force is not directly applied to the decorative body. Therefore, in the caulking work, the possibility that the decorative body is chipped or broken is low.

  The fragile material composing the decorative body is a natural material of animal or plant origin such as shellfish, animal horns, fangs or bones, or a gem or imitation jewel. As shellfish, for example, Akoya oyster can be used, and imitation jewelry is often processed crystal glass. For example, a crystal glass processed product known under the name “Swarovski” (trademark) derived from the name of the manufacturer can be used in the industry.

  Preferably, the processed crystal glass product has an upper and lower cut surface, the upper cut surface is pressed by an edge of the surface material, and the lower cut surface is supported by a receiving portion of the center seat. . Thereby, the decorative body is stably supported.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a developed perspective view of a rivet 1 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view before attachment to an object, and FIG. 3 is a cross-sectional view after attachment.

  In order from the top, there are a surface material 2, a decorative body 3, a center seat 4, a base 5 with legs 51, and a backing material 6.

  The surface material 2 is made of metal and imitates the shape of a petal, and a central portion is a through hole 21. A peripheral edge 22 is formed around the through hole. As shown in the enlarged view of FIG. 3, a claw 23 for preventing rotation is formed on the lower surface of the surface material 2. A first step portion 24 is formed in the through hole 21 slightly below the edge portion 22.

  Here, the decorative body 3 is a glass processed product imitating a jewel, and is known as “Swarovski” (trademark). It has an uppermost cut surface 31, an upper cut 32 surface, and a lower cut surface 33.

  The center seat 4 is a metal-made ring having a through hole 41. As shown in FIG. 2, the receiving part 42 of the decorative body in the shape of a mortar, a flat top part 43, and a peripheral flat part slightly lower than the top part form a second step part 44.

  The base 5 is a metal hollow cylinder having a flange 52 at the top, and the cylindrical part constitutes the leg part 51.

  The backing material 6 is composed of a flat material 61 and a protrusion 62, and is used for caulking from the back side of the fabric to the surface side rivet component.

  To assemble them, contrary to the above description, the base 4 and the decorative body 3 are placed on the base 5 and the surface material 2 is covered so that the decorative body 3 can be seen from the through hole 21 of the surface material. Then, it is applied to the fabric 7 and caulked together with the backing material 6 from the back.

  At this time, the upper cut surface 32 of the decorative body 3 is pressed by the edge portion 22 of the surface material 2, and the lower cut surface 33 is supported by the receiving portion 42 of the center seat 4. Further, the first step portion 24 of the surface material and the second step portion 44 of the center seat are in contact with each other.

  When the rivet surface side parts and the backing material are caulked by the driving machine, the heights of these step portions are set so that the first and second step portions 24 and 44 come into contact before the decorative body 3 is pressurized. It is important to do. Thereby, the pressurizing force of the machine is absorbed by this contact portion and is not transmitted as a large pressurizing force to the decorative body 3. As a result, the decorative body 3 is not chipped or broken.

It is an expansion | deployment perspective view of the rivet which concerns on the Example of this invention. (A) is sectional drawing before attachment to the target object of the rivet which concerns on the Example of this invention. (B) is sectional drawing after the attachment of a rivet. FIG. 3 is an enlarged view of FIG.
