JP5421068B2 - Tortoiseshell color glasses frame and its manufacturing method - Google Patents

Description

  The present invention mainly relates to a temple (vine) of a spectacle frame made of tortoiseshell (blade) and a method for manufacturing the same, and more particularly to a tortoiseshell color spectacle frame having an arbitrary coloring and a method for manufacturing the same.

  Tortoiseshells are manufactured using the shells of hawksbill turtles, and currently the collection of hawksbill turtles is prohibited by the Washington Convention from the viewpoint of nature conservation. However, tortoise shell materials are still stocked in the country because of the large amount of hawksbill turtles imported in the past. In addition, the tortoiseshell can be finished to a size that constitutes each part of the spectacle frame, such as a temple or a front part, by sticking the thinly cut pieces while applying pressure using water and heat. For this reason, it is possible to meet demand with tortoiseshell materials stocked in Japan.

  By the way, the glasses frame using the tortoiseshell has a good surface feel, and can be repaired and restored to its original state even if it is damaged. There is an advantage that it can be revived by polishing. On the other hand, the color of tortoiseshell is limited from dark blue to dark brown or a mixture of these. For this reason, recently, a spectacle frame in which colors are artificially applied to the tortoiseshell has been commercialized taking advantage of the above-mentioned advantages of the tortoiseshell.

  However, eyeglass frames that have been artificially colored with a tortoiseshell frame are conventionally bonded, for example, to a temple, with a colored core interposed between two vertically divided tortoiseshell temples, Also, only a color coating of the circumference of the tortoiseshell temple has been implemented.

  There was no prior art patent document regarding the tortoiseshell color eyeglass frame. Many of the prior arts are related to resin-made spectacle frames, and as prior art related to spectacle frames using materials other than resin, at least one of the parts constituting the spectacle frame is made of paper, and the paper parts are The thing which impregnated resin inside and performed the coating process is proposed (for example, refer patent document 1).

  Among the conventional tortoiseshell color eyeglass frames, the former has a poor appearance because the line pasted at the intermediate position in the thickness direction of the temple remains. Moreover, since it can be seen from the appearance that a colored core material is inserted, it is unnatural. In the latter case, the color coating part comes into contact with the skin, and the peculiar touch of the tortoiseshell frame is not felt. When the color coating is peeled off, the background of the tortoiseshell frame appears, so the appearance is bad. Furthermore, both the former and the latter are difficult to restore to the original structure when the glasses frame is broken.

  The present invention has been made in view of the above points, and an object thereof is to provide a tortoiseshell color eyeglass frame and a method for manufacturing the same, which can be colored arbitrarily and does not impair the original advantages of the tortoiseshell frame. Yes.

  In order to achieve the above object, the tortoiseshell color eyeglass frame according to the present invention has a width of 1 centimeter or less, a length of several centimeters (for example, 2 to 5 centimeters), and a thickness of 1 millimeter or less and rough grinding on both sides. A lot of small pieces made of tortoiseshell material are leveled or stepped in the length direction and overlapped in the length direction and thickness direction to form a tortoiseshell material to the size of the temple or other parts, to form an aqueous coloring liquid Immerse the aqueous coloring liquid between the small pieces to color the tortoise shell material, heat at a predetermined temperature for a certain period of time and pressurize in the thickness direction, and then cut the piece into a predetermined shape. It is characterized by comprising a pair of temples or other parts that are shaped and polished on the surface.

  According to the tortoiseshell color eyeglass frame of the present invention having the above configuration, since the aqueous coloring liquid permeates between the small pieces of the tortoiseshell material constituting the temple or other parts, there is no color unevenness over the entire area. Coloring is applied. In addition, because the surfaces of temples and other parts that come into contact with the skin of the wearer are made of the tortoiseshell itself, the feel is good and the glasses are comfortable to wear. Therefore, unlike conventional color-coated tortoiseshell eyeglass frames, it does not feel bad or cannot be restored when damaged.

  As described in claim 2, it is preferable that the size of the small piece is 1 centimeter or less in width, several centimeters in length, and 1 millimeter or less in thickness.

  By doing so, it is possible to mold each part of the spectacle frame by overlapping the small pieces including the temple using the stock of the tortoiseshell.

  As described in claim 3, it is preferable that the tortoiseshell is made of white shell.

  If comprised in this way, the translucency of tortoiseshell material is favorable and the color of the colored liquid impregnated inside appears clearly.

In order to achieve the above object, a method for producing a tortoiseshell color eyeglass frame according to the present invention comprises a tortoiseshell material having a width of 1 cm or less, a length of several centimeters (for example, 2 to 5 cm) and a thickness of 1 mm or less. (Preferably 0.2 to 0.5 mm) a step of forming into small pieces (elongated pieces), a step of roughing both sides of the small pieces to form a rough surface, and a large number (for example, a dozen or so pieces) Ten pieces of the above-mentioned small pieces are arranged in the same or different steps in the length direction and overlapped in the thickness direction to form a small piece group of a predetermined shape (for example, a temple shape or other part shape), and water-based coloring A step of preparing an aqueous coloring liquid having a desired color by blending the liquid, a step of immersing one end side of the small piece group in the aqueous coloring liquid and infiltrating the coloring liquid between the small pieces, and a predetermined temperature. Heated and predetermined in thickness direction A step of integrating by bonding the small pieces group by chaos Rukoto with a force, the surface with finishing piece group that has been integrated is colored in cutting to a predetermined shape (e.g. temple shape or other product shape) And a step of polishing to form a temple or other part.

  According to the production method of the present invention including the above-described steps, the water-based coloring colored in a desired color in a state where thin pieces of the tortoiseshell are superposed in the length direction and the thickness direction and arranged in a predetermined shape The liquid penetrates between the pieces of tortoiseshell and exhibits the desired color. In this state, the aqueous coloring liquid penetrates between the small pieces. In this way, the small colored group is pressed and heated in a state in which the aqueous coloring liquid has permeated between a large number of small pieces, and is compressed and integrated. For example, a tortoiseshell material for temples is generally integrated into the shape of a temple. The integrated tortoiseshell material is cut into a predetermined shape, and the entire surface is polished with sandpaper or the like to prepare a temple shape and the surface is smoothly finished. In this way, a colored temple having an arbitrary coloring is formed. Similar to the eyeglass frame according to the first aspect, since the aqueous coloring liquid permeates between the small pieces of the tortoiseshell, the temple is uniformly colored throughout without any color deviation. In addition, the surface of the glasses frame is not colored, the surface of the temple that comes into contact with the skin of the wearer is polished smoothly, and it consists of the tortoiseshell itself, so that the touch of the conventional non-colored As good as tortoiseshell. In addition, the color is brighter than that of a conventional color glasses frame in which a colored plate is inserted only at an intermediate position in the thickness direction. Furthermore, even if a part of the spectacle frame is damaged, the damaged part can be repaired and restored to its original state including color.

  As described in claim 5, the length of the small piece can be 2 to 5 cm, and the thickness can be 0.2 to 0.5 mm.

  If it does in this way, while being able to shape | mold the components of arbitrary spectacles frames by superposing | stacking a small piece, it can infiltrate aqueous coloring liquid between the piled small pieces, and can give a uniform color to the whole component. . In addition, when the color glasses frame is damaged, the damaged part can be restored to the original state including the color.

  The tortoiseshell color eyeglass frame and the manufacturing method thereof according to the present invention have the following excellent effects.

  -Since the aqueous coloring liquid permeates between the small pieces of the tortoiseshell material constituting the temple or other parts, there is no color unevenness and the coloring is applied uniformly throughout.

  -The surface of temples and other parts that come into contact with the wearer's skin is made of tortoiseshell itself, so it feels good.

  ・ Since the aqueous coloring liquid is infiltrated between many small pieces, they are compressed and integrated by pressing and heating the small pieces, so even if part of the spectacle frame breaks during use, Stacked small pieces of tortoiseshell material, molded into a predetermined shape, and can be colored into any color by infiltrating the aqueous coloring liquid between the small pieces, so that the damaged part can be repaired and restored to the original .

FIG. 5 is a perspective view showing a state where a temple-shaped small piece group 9 ′ is immersed in an aqueous coloring liquid 13.

  Hereinafter, preferred embodiments of the tortoiseshell color eyeglass frame of the present invention will be described based on the drawings together with the manufacturing method thereof.

  As shown in FIG. 1, the glasses 1 of the present embodiment have two lenses 10, 10 connected together by a metal connector 3. A pair of nose pads 4 and 4 are attached to the connector 3. An armor 5 is attached to the outer end portion of each lens 10, and a metal joint 7 is connected to the armor 5 via a hinge 6 so that it can be folded by rotating approximately 90 °. And the front-end | tip part of each metal coupling 7 is embed | buried under the temple 8 made from a tortoiseshell, and is connected integrally. Therefore, the tortoiseshell color eyeglass frame 2 of the glasses 1 according to the present embodiment includes the temple 8, the connector 3, the nose pad 4, the armor 5, the hinge 6, and the metal joint 7, and only the temple 8 is made of the tortoiseshell material.

  The tortoiseshell-made temple 8 is made of amber-colored tortoiseshell called white shell, and is colored red wine in this example. The colors include amber, green, purple, etc., and are not particularly limited. The temple 8 is made from a large number of pieces of tortoiseshell material 9 (here, 40 to 50 pieces). As shown in FIG. 2, each small piece 9 has an elongated shape with a width of 1 cm or less, a length of 2 to 5 cm, and a thickness of about 0.2 to 0.5 mm in this example, and both surfaces of the small piece 9 are rough. It is formed in an uneven shape with sandpaper. These small pieces 9 are pressure-bonded under heating to be slightly larger than the shape of the temple 8, and are finally finished into a temple shape.

  As shown in FIG. 3, the small pieces 9 are arranged in the longitudinal direction or flush with each other, and are also arranged in the thickness direction so as to be shaped into the temple 8. The temple-shaped small piece groups 9 ′ are trimmed from both sides by a plurality of clamping tools 11 arranged at regular intervals in the longitudinal direction, and are held in a temple shape.

  On the other hand, in the present embodiment, a plurality of types of aqueous colored liquids (for example, aqueous color ink) 13 are injected into a cup-shaped vessel 12 having an open upper end, blended so as to obtain a desired red wine color, and the color is adjusted. . In this way, as shown in FIG. 4, a small piece group 9 'held from both sides by a plurality of holding tools 11 is inserted from one end side into a container 12 containing an aqueous coloring liquid 13 blended in a desired color. Then, the one end portion of the small piece group 9 ′ is immersed in the aqueous coloring liquid 13 in the vessel 12, and the aqueous coloring liquid 13 is sufficiently immersed between the small pieces 9.

  The small piece group 9 ′ is taken out from the vessel 12 in a state where the aqueous coloring liquid 13 is immersed in the gap between the small piece groups 9 ′ as described above.

  The small piece group 9 ′ is heated to around 100 ° C., tightened as a whole using a vise, and pressurized in the thickness direction for a certain time (usually 20 to 30 minutes). In this manner, the small piece groups 9 'are pressure-bonded to each other so as to be integrated into a temple shape.

  In this embodiment, the integrated small piece group 9 ′ is cut into a desired shape of the temple 8 using a cutting tool such as a knife, and then the shape of the temple 8 is adjusted by grinding and polishing with a grinder and sandpaper. Finish to Temple 8. When a part of the temple 8 is bent according to the shape of the user's face or ear, the bent portion is bent while heating. The colored temple 8 is finished as described above.

  In this example, the tip portion of the metal joint 7 is inserted at one end of the small piece group 9 ′ at an intermediate position in the thickness direction before heating and pressurizing the small piece group 9 ′. As a result, the small piece group 9 'is pressure-bonded and integrated in a state where the tip end portion of the metal joint 7 is inserted into one end side of the small piece group 9'. Instead of inserting a part of the metal joint 7 in this way, the metal joint 7 can be screwed to the end of the temple 8 using a plurality of screws.

  In the above-described embodiment, the tortoiseshell temple 8 has been described. However, any portion of the spectacle frame 2 may be a tortoiseshell material. For example, the front portion (glasses frame) and the nose pad 4 are made of tortoiseshell material. The case is similarly formed. The aqueous coloring liquid is not limited to the aqueous color ink as long as the aqueous paint is dissolved in distilled water. Furthermore, the tortoise shell material is not limited to the white shell, but may be, for example, an orange shell or a white tiger shell.

  The tortoiseshell color eyeglass frame 2 is completed by connecting the metal joint 7 of the temple 8 manufactured through the above steps to the armor 5 with the hinge 6.

  Next, advantages of the eyeglass frame 2 manufactured as described above, particularly, the tortoiseshell-made temple 8 will be described.
