Description

  The present invention relates to a decorative resin spectacle frame.

  Conventionally, most resin spectacle frames are made by cutting a sheet-shaped resin plate. Certainly, it was richer in color than the one made by injection molding, and it was sufficiently dry and easy to process. However, there are few sheet materials that have abundant colors but are designed with patterns. Therefore, in order to attach such a designed pattern, it has been practiced to bond two sheets of material and print a decorative pattern on the bonded surface. For example, as disclosed in Japanese Patent Application Laid-Open No. 04-221924, a technique of transferring a pattern onto a resin and coating it by using a solvent of a transparent resin is introduced.

JP 04-221924

  However, in the above method, when the part is used as a temple, a cored bar must be inserted therein to be reinforced. In that case, the part machined and cut into a temple mold is heated to 70 ° C. to 150 ° C. to make it softened tofu or konjac, and the core metal mold is heated to 200 ° C. to 350 ° C. at a high frequency to shoot and open the core hole. Insert gold. In that case, the transfer pattern of the parts often flows, and the bonded surface often deviates from the adhesive surface. Even after cooling, the temple is repeatedly bent and stretched in accordance with the shape of the human ear. And in such a case, there were many cases where a crackling sound and peeling off occurred. In the case of a core tension, which is a laminate of ordinary sheet plates, it is an accident that is unlikely to occur, but it is also likely to occur on the decorative surface.

  Therefore, in the present invention, in order to solve the above-mentioned problem, at least one of them is a resin decorative frame that is laminated from at least two resin plates, and the surface of the first substrate is polyurethane. It is characterized in that a decorative pattern is printed with a system ink, an adhesive layer is applied from above, and a transparent layer is formed with a polyurethane system ink on the bonding surface of the other second substrate to be bonded. Adopted a plastic eyeglass frame.

  The resin eyeglass frame is a temple, and a core metal or a core metal mold is shot in the first base material or the second base material of the temple cut into a predetermined shape and heated in a softened state. Provided plastic eyeglass frames.

  Provided is a resin spectacle frame in which the resin spectacle frame is a front frame and can be shaped by heating.

  And, at least one of them is a resin plate for a decorative frame made of resin that is laminated from at least two resin plates, and a decorative pattern is printed on the surface of the first substrate with polyurethane ink, and an adhesive layer It is also possible to provide a decorative resin plate for spectacles, characterized in that a transparent layer is formed with a polyurethane-based ink on the bonding surface of the other second base material coated and bonded from above. Become.

  Even when molding as a temple by the technique of the present invention, the decoration may flow even if the resin eyeglass frame is heated to a softened state and a hot core metal or core metal mold is shot. In addition, even when the temples were repeatedly bent and stretched after cooling, there was no occurrence of cracks and no peeling from the printed surface. Also, since printing is different from transfer, vivid colors can be expressed.

  At least one of them is a resin decorative frame that is laminated from at least two resin plates. A decorative pattern is printed on the surface of the first substrate with polyurethane ink, and an adhesive layer is applied from above. A resinous spectacle frame characterized in that a transparent layer is formed with polyurethane-based ink on the bonding surface of the other second base material to be bonded.

  FIG. 1 is an enlarged sectional view of an essential part of an embodiment of the present invention. At least one of them is a resin decorative frame 10 that is laminated from at least two resin plates that are transparent. A decorative pattern 13 is printed on the surface of the first substrate 11 with polyurethane-based ink, and an adhesive layer 14 is formed. A transparent layer is formed of polyurethane-based ink 15 on the bonding surface of the other second base material 12 which is applied and bonded from above.

  FIG. 2 is a cross-sectional view of the main part in a state in which two resin plates are bonded to each other from FIG. In this case, it may be about 24 hours for natural drying. As a printing method used for the decorative pattern, silk screen printing, pad printing or the like is preferable.

  In the case of FIGS. 1 and 2, the upper second substrate 12 is transparent, but both may be transparent or the first substrate 11 may be transparent. Then, after the decorative pattern 13 is printed with a polyurethane-based ink and dried, an adhesive 14, in this case, a thermosetting adhesive is preferable. For example, an epoxy-based adhesive, a polyurethane-based adhesive, an acrylic-based adhesive Etc. are applied. A feature of the present invention is that a transparent layer 15 is formed on the surface of the base material 12 to be bonded with a polyurethane resin or an adhesive. This may be printing, spraying, brush painting, or the like.

  FIG. 3 is a front view when the resin eyeglass frame is a temple 20, and FIG. 4 is an AA cross-sectional enlarged view thereof. A state in which the core metal or the core metal mold 22 is shot in the first base material or the second base material of the temple cut into a predetermined shape and heated to a softened state at a temperature of 70 ° C. to 150 ° C. It is. Of course, the core must be inside the decorative pattern.

  FIG. 5 is a front view in the case where the resin spectacle frame is the front frame 30. Even when the shape is adjusted by heating, the pattern does not flow or peeling at the boundary surface hardly occurs.

FIG. 6 is a perspective view of a resin decorative plate 40 used for a resin spectacle frame. A resin plate for a decorative frame made of resin that is laminated from at least two resin plates, at least one of which is transparent, and a decorative pattern 13a is printed on the surface of the first substrate 11a with polyurethane-based ink, and an adhesive layer Is a decorative resin plate for spectacles in which a transparent layer is formed with a polyurethane-based ink on the laminating surface of the other second substrate 12a to be applied and laminated, and in this way, the temple Or strips P and P1 of the size of the front frame. Thereafter, when forming into a temple, the cored bar or cored mold 22a is shot on the temple 20a as shown in FIG. Alternatively, the front frame is cut and heated to be bent into the shape of a human face. Even in such a case, it is difficult to cause a situation where peeling at the bonding interface, blurring of the decorative pattern, or flowing.
