Description

  The present invention relates to a decorative body mounting structure, and more particularly to a mounting structure and a mounting method for mounting a decorative body such as natural stone to a spectacle lens.

Conventionally, as a structure for attaching a jewel such as diamond to a spectacle lens, for example, as shown in FIG. 9, the base material 1 such as a plastic substantially corresponds to the shape of the jewel 4 to be set and is smaller than the outer shape of the jewel. A hole 3 is drilled, a groove 7 along the circumferential direction is formed inside the opening of the hole to form a locking edge 8, and the vicinity of the hole is softened by heating, and then the gem 4 is drilled. There is known a technique for press-fitting into 3 and engaging the locking edge 8 with the outer peripheral edge 10 of a jewel (see Patent Document 1).
In addition, the said code | symbol is a code | symbol in the said prior | preceding literature, and it is the same also in description of patent documents 2 thru | or 4 below.

  However, since this technique “heats” the vicinity of the opening and “presses in” the gemstone, the spectacle lens itself, which is the base material, is distorted, and as a result, the surface coat may peel off in a short period of time. . Holes are drilled on the surface of the spectacle lens where multiple layers of coating treatments have been applied, such as an anti-scratch coating, anti-reflection coating, impact resistance coating, anti-smudge coating, anti-fogging coating, and anti-static coating. As a result, the opening has already become fragile, and if it is “heated” or “press-fitted”, it is inevitable that the eyeglass lens will be burdened more than expected by the product.

  In addition, the technique does not plan to replace gemstones, and if the gemstones once attached are removed, the substrate is very likely to be damaged. A solution has been desired in that it cannot satisfy the demand for removing expensive gemstones such as diamond from glasses that are no longer suitable and replacing them with new glasses.

  Furthermore, according to the technique, it is impossible to attach a large gem exceeding the thickness of the base material because of its configuration. With the recent progress in technology, the lens has been made thinner. In this technique, the outer peripheral edge 10 of a jewel is engaged with the groove 7 and the engaging edge 8 provided along the circumferential direction inside the opening. A large jewel cannot be attached to the lens. That is, the distance from the girdle (reference numeral 23 in FIG. 4) to the curette (reference numeral 22 in the figure) cannot always exceed the thickness of the substrate.

  In addition, a “groove” along the circumferential direction is formed inside the opening of the hole to form a “locking edge”, and the vicinity of the hole is softened by heating, and then the gem is pressed into the hole. In the method, it is extremely difficult to adopt a design in which a plurality of diamonds are arranged so close to each other that the girdle contacts each other.

Further, in this technical document, “having a problem that must be solved by firmly and securely attaching a gemstone to a base material such as a plastic plate” (paragraph “0007”), “. The neighborhood is softened by heating, and then the jewel is press-fitted, ... "(" Claim 1 ")," The flexible substrate is a plastic ... "(" Claim 3 "), “Drill a hole in the spectacle lens…, soften the vicinity of the hole by heating, and then press-fit diamond into the hole (“ Claim 4 ”),“ The method for attaching a jewel according to the present invention is: .. When setting on a soft plastic substrate, etc. ”(paragraph“ 0035 ”), according to the technology, it is suitable for the process of“ heating ”and“ press fitting ”. Such as plastic with certain “softness” Limited to wood. However, the base material to which the jewel is attached is not limited to such a soft material. Therefore, there is a need for a technique that can be securely attached regardless of the hardness of the material.
In this document, there is no specific disclosure even though “... a glass product etc. can be applied” (paragraph “0034”), and it is assumed that the substrate has flexibility. Is not consistent with the explanation. For example, although there are lenses made of glass as a spectacle lens, it has not been verified whether `` heating '' or `` press-fitting '' by the technology can be used without impairing the quality of delicate optical glass products, Whether or not it can be implemented is unknown.

  Further, as shown in FIG. 10, the eyeglass lens 12 has a hollow portion 28a formed with a substantially constant diameter from the surface of the lens 12, and the end of the hollow portion 28a is inclined from the periphery of the hollow portion 28a toward the center portion. A technique is known in which a decorative body 26 is fixed to a bottomed hole 28 composed of a bottom surface portion 28b formed in accordance with the inclination of the bottom surface of the decorative body 26 via an adhesive layer 30 (Patent Document 2). reference).

The type of adhesive used in the art is not disclosed, but generally a two-component mixed epoxy adhesive is used for this type of decoration. It is an adhesive recommended by lens manufacturers because it is easy to obtain and is hardened by chemical changes, so there is little damage to the lens, and the elasticity unique to the resin contributes to impact resistance.
However, a two-component mixed epoxy adhesive cannot avoid discoloration over time and impairs the shine of the jewel, which is contrary to the original purpose of improving the aesthetics of spectacles by decorating a spectacle lens. Furthermore, a decrease in adhesion due to aging leads to the loss of expensive jewelry. In addition, it has been pointed out that when the glasses on which the jewelry is fixed with the adhesive are repeatedly cleaned with an ultrasonic cleaner, the deterioration speed is accelerated.

  In addition, like the technique described in Patent Document 1, this technique does not plan to replace the gemstone, and if the gemstone once attached is removed, the base material is very likely to be damaged. . A solution has been desired in that it cannot satisfy the demand for removing expensive gemstones such as diamond from glasses that are no longer suitable and replacing them with new glasses.

  Furthermore, in the same manner as the technology described in Patent Document 1, it is impossible to attach a large gem exceeding the thickness of the base material. With the recent progress in technology, the lens is becoming thinner. With the technique of fixing the decorative body 26 to the “bottom hole 28” via the adhesive layer 30, it is not possible to attach a large jewel to a thin lens. That is, the distance from the girdle (reference numeral 23 in FIG. 4) to the curette (reference numeral 22 in the figure) cannot always exceed the thickness of the substrate.

  Further, as shown in FIG. 11, the lower surface of the jewel 1 is coated with a first thin layer 2 having a band-like thickness of several μm to several tens μm by sputtering or ion plating using a metal such as gold or palladium. Then, a second thin layer 2-2 such as gold or palladium having a thickness of several tens to several hundreds μ is formed on the surface of the thin layer by means of electroless plating or the like. The jewel 1 is fitted into a jewel etc. holding hole 4 provided in the base material 3 such as a finger ring, and the thin layer member 2 of the jewel protruding from the lower opening and the base material 3 in the vicinity thereof are joined by brazing or spot welding or the like. A technique for bonding and fixing by means and molding the bonded portion 5 is known (see Patent Document 3).

  However, in order to deposit gold or palladium on gemstones by the sputtering method or ion plating method as used in the art, a special environment and apparatus for applying a high voltage in a vacuum must be prepared. A handling operator is also required. Therefore, the cost of these special facilities and specialized personnel is added to the decoration cost. The feature of the technology is to form two thin layers, and to apply a relatively thick second layer in consideration of brazing with the base material 3 to the thin first layer applied to the gemstone. It can be attached firmly as a whole. However, as described above, the film forming process itself is special, and if a film forming process with a different thickness is required, it is difficult to say that this technique can be easily used by anyone.

  Also, brazing and spot welding are mainly metal joining methods, and the materials that can be used are limited. In particular, they are techniques that are not suitable for using glasses lenses as materials.

  Also, as shown in FIG. 12, a technique is known in which a decorative body 2 is fixed by caulking a holding portion 10 and a female portion 5 that hold the decorative body 2 via a body to be decorated 20 (see Patent Document 4). .

  However, this technique requires a plurality of types of predetermined members, such as spacers of various shapes used in various fixing methods, in addition to the holding part and the female part, when attaching one decorative body to the object to be decorated. And

  In addition, the method of “caulking” and fixing the holding portion and the female portion via the body to be decorated is caulked as can be confirmed in FIGS. 1B and 4B and other drawings in the document. Since the periphery of the hole is deformed, it is not suitable for delicate materials such as spectacle lenses that are expected to be damaged by a load exceeding a certain level.

  Furthermore, since the girdle of the decorative body always protrudes from the body to be decorated, there is a risk that it will be caught by other objects during use. Further, when this is applied to a spectacle lens, the female part enters the field of view, which is not preferable in terms of the practicality of the spectacles.

Japanese Patent Laid-Open No. 7-88004 (FIGS. 2 and 3) Utility Model Registration No. 3103063 (Fig. 3) JP-A-62-236504 (FIGS. 1 to 3) Japanese Patent No. 4170142 (FIG. 1)

  Therefore, the object of the present invention is not limited to the conventional idea of attaching a decorative body to a base material by the adhesive force of an adhesive when attaching a decorative body such as natural stone to a lens for glasses or other plate-like base material, and for a long time. The decorative body can be fixed with as much as possible without disturbing the brightness of the decorative body as much as possible, and the decorative body can be freely arranged without placing a burden on the base material when the decorative body is attached to or detached from the base material. On the other hand, it is an object to provide an attachment structure and a method for attaching a decorative body that can be attached with a simple configuration and process.

Mounting structure of the decorative body according to the present invention is a mounting structure of the decorative body of the plate-shaped substrates, the decorative body, the maximum diameter or a maximum width at the boundary between the upper and the substantially inverted cone-shaped lower It is a decorative body, and roughly corresponds to the lower shape of the decorative body , which is formed in the front opening of a through hole drilled at a desired diameter of the base material with a diameter not exceeding the maximum diameter or maximum width of the decorative body. in a state where the decorative body to Table conical recess is placed over the UV curable resin, a surface cyclic resin obtained a boundary between the peripheral edge and said surface conical recess of the ornamental body so as to cover the UV-curable resin Part, a back surface annular resin part made of an ultraviolet curable resin applied to a back cone-shaped recess chamfered at the back opening of the through hole, and ultraviolet light applied between the front cone-shaped recess and the lower part of the decorative body most major to become cured integrally as a resin portion and are continuously cured resin portion And features.

  Moreover, the attachment structure for a decorative body according to the present invention is the structure according to claim 1, wherein the inner wall surface of the front cone-shaped recess substantially corresponds to the lower shape of the decorative body, and the lower part of the decorative body and the It is characterized by having a gap secured between the inner wall surface and the inner wall surface.

  Moreover, the attachment structure for a decorative body according to the present invention is characterized in that, in the configuration according to claim 1 or 2, the base material is a lens for spectacles.

  Further, the method of attaching the decorative body according to the present invention to a plate-like base material is such that the decorative body has a maximum diameter or maximum width at the boundary between the upper part and the substantially inverted conical lower part, A through-hole with a diameter that does not exceed the maximum diameter or maximum width of the decorative body at a desired position, and in the through-hole, a back cone-shaped recess in which the back opening of the through-hole is chamfered conically, After forming a front cone-shaped recess roughly corresponding to the lower shape of the decorative body at the front opening of the through hole, an ultraviolet curable resin is applied to both the cone-shaped recesses, and the resin is applied to the front cone-shaped recess. The decorative body is installed via the surface annular resin portion formed so that the resin covers the boundary between the peripheral edge of the decorative body and the front cone-shaped concave portion, and applied to the back cone-shaped concave portion. The back surface annular resin portion and the ultraviolet curable resin portion applied between the front conical recess and the lower portion of the decorative body are connected. After forming the resin portion, and characterized by being cured integrally the resin portion is irradiated with ultraviolet light.

  According to the attachment structure for a decorative body according to claim 1, the front surface circular resin portion and the back surface circular resin with an annular resin reservoir covering the boundary between the peripheral edge of the decorative body and the front cone-shaped concave portion in the front cone-shaped concave portion. And a UV-curable resin portion applied between the front cone-shaped concave portion and the lower part of the decorative body form a continuous resin portion, and the resin portion is integrally cured by being irradiated with ultraviolet rays. It becomes. If it does so, the said cyclic | annular resin reservoir will become a nail | claw which hold | maintains a decoration body in a base material, and this fat reservoir part hardened | cured integrally with this nail | claw will shape | mold a rivet body. Even if the adhesive force of the ultraviolet curable resin is lost, the decorative body does not fall from the base material as long as the shape of the rivet body is maintained. The invention embodies a new idea of molding a rivet body with a resin, without being bound by the conventional idea of attaching a decorative body to a substrate depending on the “adhesive strength” of an adhesive.

  The ultraviolet curable resin does not change color in a short period of time as in the case of a two-component mixed epoxy adhesive, and maintains a colorless and transparent state for a long period of time. Further, even if the ultrasonic cleaner is repeatedly used, the deterioration speed of the resin is not promoted, so that maintenance is easy.

  And since a heat | fever and a pressure are not applied when installing a decoration body to the surface opening part of a base material via ultraviolet curable resin, there is no burden to a base material.

  In addition, a large decorative body exceeding the thickness of the base material, that is, the distance from the girdle (reference numeral 23 in FIG. 4) to the culet (reference numeral 22 in the same figure) by the configuration in which the through holes are provided in the base material is It is possible to attach a decorative body exceeding the thickness. The depth at which the decorative body is installed is not particularly determined if the surface annular resin portion is molded so that the resin covers the boundary between the peripheral edge of the decorative body and the front cone-shaped concave portion. In addition, it is possible to design freely according to the taste of the customer, the decorative body, the shape of the base material, and the like. In addition, since a holding member or the like for holding the decorative body is unnecessary, it is possible to arrange a plurality of decorative bodies so as to come into contact with each other, and the degree of design freedom is significantly improved as compared with the prior art.

  In addition, when it is set as the structure of Claim 2, since a fixed space is ensured between the lower part of a decoration body and a conical recessed part, in the case of a decoration body like a round round brilliant cut, for example, light The omnidirectional reflection is not hindered and the original brightness is maintained.

  Moreover, when it is set as the structure of Claim 3, the above-mentioned effect can be enjoyed about the lens for spectacles.

  And according to the attachment method of the decoration body of Claim 4, the attachment structure of the decoration body which enjoyed the above-mentioned effect can be obtained.

[First embodiment]
Next, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a basic embodiment of the present invention, FIG. 1 (a) is a sectional view showing a mounting state of a decorative body of this embodiment, and FIG. 1 (b) is a partially enlarged view thereof. FIG. 2 is a flowchart showing an example of a procedure for attaching the decorative body 2 to the substrate 1. FIG. 3 shows a back cone-shaped recess 5 in the back opening 31 of the through hole 3 and a front cone in the front opening 32. It is a figure which shows an example of the procedure which shape | molds the recessed part. FIG. 4 is a diagram for explaining the names of general gem parts. FIGS. 5 (a) and 5 (b) are partial perspective views for explaining the front annular resin portion, and FIG. 4 (c) is the back annular resin portion. It is a fragmentary perspective view explaining these.

  In this embodiment, a plastic lens for spectacles is used as a base material 1 and a through hole 3 is drilled at a predetermined position. Then, a back cone-shaped recess is formed in the back opening of the through hole, and a front cone-shaped recess is formed in the front opening. Are respectively attached to the base material 1 using a UV curable resin 7 with a round brilliant cut diamond as a decorative body 2. Details will be described below.

First, after determining the mounting position of the decorative body 2 and marking the surface of the base material 1 (S101), a through hole 3 having a diameter of about 1 mm is cut into the mounting position using a known drill or the like, and cutting oil is used. Drilling while refueling (S102). The cutting oil may be supplied as necessary in consideration of the material of the base material.
The through-hole 3 is formed with a diameter not exceeding the maximum diameter of the decorative body 2, that is, the diameter of the girdle portion (FIG. 4, reference numeral 23). At this time, the through-hole 3 is preferably drilled from the surface side of the substrate 1. This is because the setting angle of the decorative body depends on the angle of the through hole with respect to the lens surface, and the spectacle lens has a different front curve and back curve in order to generate the lens power. This is because it is easier to adjust the angle.
The known drills and the like are suitable for the material of the base material, and laser drilling and other known drilling methods are not excluded, regardless of the type of drill or the material thereof, as long as a through hole with a desired diameter can be drilled.

  Next, as shown in FIG. 3, first, the back opening 31 of the through-hole 3 is chamfered to a predetermined depth like a countersink using a known cutting tool such as a counter sink, and the back cone-shaped recess 5 is formed. (S103). Although the said back cone-shaped recessed part 5 is provided in order to shape | mold the back surface cyclic | annular resin part 72 in FIG.5 (c) mentioned later, since it also affects the beauty | look of a lens, the shape of a decorative body, and other attachment conditions In consideration of the above, it is desirable to keep the depth and angle suitable for the purpose.

Next, in the front opening 32 of the through-hole 3, the front cone-shaped recess 6 that roughly corresponds to the substantially conical shape of the lower part of the decorative body 2 is formed (S104). At this time, in view of the object of the present invention, it is necessary to set the decorative body 2 so that the girdle 23 of the decorative body is slightly lower than the surface p of the base material 1 as shown in FIG. The surface cone-shaped recess 6 is formed with a diameter slightly larger than the maximum diameter of the decorative body 2, that is, the diameter of the girdle part. In this embodiment, the surface pyramid-shaped recess 6 is formed with a diameter larger by about 0.1 to 0.2 mm than the diameter of the girdle portion of the decorative body 2.
When forming the front cone-shaped concave portion 6, similarly to the back cone-shaped concave portion 5, the entrance of the front opening portion 32 is initially set to a predetermined depth like a countersink using a known cutting tool such as a counter sink. And expand the hole in a conical shape.
In addition, it is good also as the above-mentioned reverse about the order of the shaping | molding order of the back cone-shaped recessed part 5 and the front cone-shaped recessed part 6. FIG.
Then, the processed portion is washed with alcohol or the like to remove shaving residue and other impurities during processing (S105).

Next, after the ultraviolet curable resin 7 is applied to almost the entire surface of the front cone-shaped concave portion 6 and the back cone-shaped concave portion 5 (S106), the decorative body 2 is installed and fitted into the front cone-shaped concave portion 6 (S107). Then, due to the viscosity of the resin 7, the periphery of the decorative body 2 exposed in the front cone-shaped recess 6, that is, the ring h covering the boundary h between the girdle 23 and the front cone-shaped recess 6 shown in FIG. The surface annular resin portion 71 with the resin reservoir 711 is formed (FIGS. 1 and 5A). This annular resin reservoir 711 becomes a claw for holding the decorative body 2 on the base material 1 after curing.
FIG. 5B is drawn for the sake of convenience in order to clarify the boundary h.
In view of the object of the present invention, the resin 7 is preferably a type that maintains transparency over a long period of time or a non-yellowing type ultraviolet curable resin.

  As described above, the front surface circular resin portion 71 (FIG. 5A), the back surface circular resin portion 72 (FIG. 5C) obtained by applying the ultraviolet curable resin 7 to the back cone-shaped concave portion 5, and the front cone. It is confirmed that the ultraviolet curable resin portion 73 applied between the concave portion and the lower part of the decorative body forms a continuous resin portion, and the entire substrate 1 is irradiated with ultraviolet rays by a known apparatus or method. (S108), the resin parts 71, 72, 73 are integrally cured, and the attachment process of the decorative body of this embodiment is completed.

  According to the present embodiment, according to the attachment structure for a decorative body according to claim 1, the front surface annular resin portion 71 with the annular resin reservoir 711, the back surface annular resin portion 72, and the front cone-shaped concave portion The ultraviolet curable resin part 73 applied between the lower part of the decorative body forms a continuous resin part, and the resin part is integrally cured by being irradiated with ultraviolet rays. As a result, the annular resin reservoir 711 becomes a claw for holding the decorative body on the base material, and the fat portion cured integrally with the claw forms a rivet body, so that the adhesive force of the ultraviolet curable resin is temporarily lost. As long as the shape of the rivet body is maintained, the decorative body does not fall from the base material.

  As a result of maintaining the colorless and transparent resin for a long period of time, the ultraviolet curable resin in the present embodiment does not hinder the brightness of the decorative body 2 and does not cause deterioration of the resin even when an ultrasonic cleaner is used.

  As is clear from the above process, since the decorative body is simply placed on the front opening of the base material via the ultraviolet curable resin, there is no burden on the base material due to heat or pressure.

  If the resin portions 71, 72, 73 are continuously and integrally cured, the ultraviolet curable resin 7 may not be applied to the entire surface of the front cone-shaped concave portion 6 and the back cone-shaped concave portion 5. For example, if the resin parts 71, 72, 73 form a resin part connected linearly or spirally and, as a result, are continuously and integrally cured, the rivet effect is exhibited.

  When removing the decorative body 2 from the base material 1, the back surface annular resin portion 72 is scraped off and then the curette (FIG. 4, reference numeral 22) of the decorative body is pushed out toward the surface of the base material.

[Second Embodiment]

The drilling process and attachment procedure of the base material 1 are the same as those in the first embodiment except for those based on the difference in shape and size of the decorative body 2, and the reference numerals in the drawing are also common to the previous embodiment.

According to the method of Patent Document 1 or Patent Document 2 described above, it was difficult to attach a large decorative body exceeding the thickness of the base material. However, according to the present embodiment, the front surface annular resin portion 71 with the annular resin reservoir 711, the back surface annular resin portion 72, and the ultraviolet curable resin applied between the front cone-shaped concave portion and the decorative body. As long as the resin portion 73 is continuously and integrally cured, the rivet effect is exhibited, and there is no problem even if the curette 22 is a large decorative body 2 that protrudes from the back cone-shaped concave portion 5 of the substrate 1. Can be attached.
In addition, according to the present embodiment, there is no need to use a vapor deposition means that requires a specialized special device as in Patent Document 3, and no complicated components as in Patent Document 4 are required.
