Description

  The present invention relates to a decorative structure for spectacles, and more particularly to a decorative structure for spectacles in which jewels or imitations of jewels are embedded in, for example, lenses or other spectacle parts of spectacles.

  In order to decorate the spectacles 1, for example, as shown in FIG. 13, a decorative body 3 formed of crystal glass or the like is attached to the lens 2 of the spectacles 1. In order to provide such decoration, a bottomed hole 4 having a flat bottom surface is formed in the lens 2 as shown in FIG. The decorative body 3 having a flat bottom surface is inserted into the bottomed hole 4, and the decorative body 3 is fixed to the lens 2 by an adhesive layer 5 or the like (for example, see Patent Document 1).

  In the spectacles 1 having such decoration, it is conceivable to use a decorative body 3 cut in the same manner as a jewel, as shown in FIG. Such a decorative body 3 is cut so as to have multiple faces, light is refracted in the decorative body 3 in a complicated manner, and has excellent brightness. However, since the bottom surface of such a decorative body 3 is not flat but has a protruding shape, when embedded in the bottomed hole 4 having a flat bottom surface, an unstable fixing structure results. Therefore, as shown in FIGS. 16 and 17, the bottomed hole 4 formed in the lens 2 is inclined so as to gradually narrow from the surface of the lens 2 toward the bottom according to the shape of the bottom surface of the decorative body 3. Thus, it is possible to stabilize the decorative body 3.

  However, even if the structure shown in FIGS. 16 and 17 is used, when the lens 2 is wiped or the like, a force in the surface direction of the lens 2 is applied to the head of the decorative body 3. There is a problem that a force acting to move the decoration 3 along the decoration 3 is likely to cause the decoration 3 to come off the lens 2. As shown in FIG. 18, if the decorative body 3 is inserted into the bottomed hole 4 so that the head of the decorative body 3 does not protrude from the surface of the lens 2, when the lens 2 is wiped, 3 can be prevented from being applied with force. However, when the decorative body 3 is completely inserted into the bottomed hole 4, the incidence of light on the decorative body 3 is reduced, and even if the decorative body 3 having a multi-face cut is used, good shine cannot be obtained.

  Therefore, a main object of the present invention is to provide a decorative structure for eyeglasses in which the decorative body can be attached to the eyeglass component with good shine, and the decorative body is hard to come off.

The present invention is a spectacle decorative structure including a bottomed hole formed at a desired portion of spectacle parts constituting the spectacles, and a decorative body inserted into the bottomed hole and fixed by fixing means. The bottom hole is constituted by a hollow portion formed with a substantially constant diameter from the surface of the eyeglass component, and a bottom portion formed so as to be inclined in accordance with the bottom shape of the decorative body following the hollow portion. It is a decorative structure of eyeglasses, which is a feature.
In such a decorative structure for spectacles, the bottom portion can be formed so as to be gradually deeper from the periphery of the cavity toward the center at the end of the cavity.
Further, the decorative body may be arranged so as to protrude from the surface of the eyeglass component by substantially the same height as the depth of the cavity.
Furthermore, a birthstone or an imitation of a birthstone can be used as a decoration.

As the bottomed hole, a hollow portion having a substantially constant diameter is formed from the eyeglass component, and subsequently, a bottom portion that is inclined according to the bottom shape of the decorative body is formed. By inserting the decorative body into this bottomed hole, the decorative body having a protruding bottom surface is arranged along the bottom surface of the bottomed hole. Further, since the bottomed hole has a cavity formed with a substantially constant diameter from the surface of the spectacle parts, the decorative body inserted into the bottomed hole does not move in a direction parallel to the surface of the spectacle member. It is regulated by the side wall of the cavity.
The shape of the bottom surface of the bottomed hole can be, for example, a shape that gradually becomes deeper from the periphery of the end of the cavity toward the center.
Further, by arranging the decorative body so as to protrude from the surface of the eyeglass component by a predetermined height, light can easily enter the decorative body, and the incident light can be refracted in the decorative body to obtain a good shine. It is possible to enhance the decorative effect of the glasses.
For example, a birthstone or an imitation of a birthstone can be used as a decorative body used in such a decorative structure for glasses.

According to this invention, the decorative body is inserted into the bottomed hole formed in the eyeglass component, and the decorative body is stably fixed to the eyeglass component in the bottomed hole. Therefore, it is difficult to apply a force for the decorative body to come off from the bottomed hole, and it is possible to obtain a spectacle decorative structure that is hardly damaged. Further, by making the decorative body protrude from the surface of the eyeglass component by a predetermined amount, it is possible to obtain a good shine.
In addition, by using a birthstone of an eyeglass purchaser or an imitation of a birthstone as an ornament inserted into the bottomed hole of the eyeglass member, the eyeglasses can be strongly connected to the purchaser.

  The above and other objects, features and advantages of the present invention will become more apparent from the following description of the best mode for carrying out the present invention with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing an example of spectacles having the spectacle decorative structure of the present invention. The glasses 10 are composed of lenses 12 which are optical components, and non-optical components such as a front including a bridge 14, a rim 16, and a clasp 18, a hinge 20, a temple 22, and a modern 24. In the glasses 10 shown in FIG. 1, a plurality of decorative bodies 26 are attached near the periphery of the lens 12. The decorative body 26 may be attached to any position of the lens 12 as long as the place does not hinder the view.

  The decorative body 26 is formed of a special glass such as crystal glass, for example, and is cut into a shape similar to a jewel. That is, as shown in FIG. 2, the decorative body 26 has, for example, a shape in which the central portion of the upper surface is flat, the periphery thereof is cut into multiple surfaces, and the bottom surface protrudes. In addition, since the projecting portion on the bottom surface of the decorative body 26 is also cut into multiple faces, light incident on the decorative body 26 is refracted intricately, and a beautiful shine can be obtained.

  A bottomed hole 28 is formed in the lens 12 for attaching the decorative body 26. The bottomed hole 28 is formed, for example, on the convex side of the lens 12. Then, as shown in FIG. 3, a hollow portion 28 a having a substantially constant diameter is formed as a bottomed hole 28 from the surface of the lens 12, and following the hollow portion 28 a, from the periphery, according to the bottom shape of the decorative body 26. A bottom surface portion 28b is formed so as to gradually become deeper toward the center. The diameter of the hollow portion 28 a of the bottomed hole 28 is formed so as to be substantially equal to the diameter of the decorative body 26.

  In order to form such a bottomed hole 28, as shown in FIG. 4, first, the assembled glasses 10 are held in a predetermined posture by a jig 50 as holding means. The jig 50 is formed of an elastic synthetic resin material or the like so as not to damage the spectacles 10 even when the jig 50 contacts the spectacles 10. The jig 50 includes a groove 52 provided on its upper surface so as to extend in the longitudinal direction. The jig 50 is supported by the shaft 54 so as to be vertically movable. The shaft portion 54 is appropriately moved up and down by a vertically moving displacement means (not shown).

  The eyeglasses 10 have the one main surface side of the lens 12 facing upward, one temple 22 and the modern 24 side are fitted into the groove 52 in a state of being bent at the hinge 20 part, and the other temple 22 and the modern 24 side are inserted from the groove 52. It comes out. In this case, since the rim 16 side of the glasses 10 is supported near both edges in the width direction of the groove 52, the lens 12 is held by the jig 50 with one main surface thereof facing upward.

  Then, in the lens 12 of the spectacles 10 held in a predetermined posture by the jig 50, a bottomed hole 28 is formed in a predetermined portion by a drilling device. In this embodiment, for example, a drilling machine 100 as shown in FIG. 5 is used as a drilling device. Drilling machine 100 includes a base 102. On the base 102, a column 104 is provided. The column 104 is provided with a spindle head support 106. A handle 108 and a spindle head 110 are attached to the spindle head support 106, and a motor (not shown) is built in. The spindle head 110 has a drill chuck portion 112, and a cutting tool 114 as a drilling tool is detachably attached to the drill chuck portion 112. The cutting tool 114 includes a handle (shank) 116, for example, as shown in FIG. The handle (shank) 116 has a tongue (knob) 116a on one side in the axial direction and a blade 118 on the other side in the axial direction via a neck 116b. The blade portion 118 is composed of a body portion 118a that forms a hole with a constant diameter, and a tip portion 118b that is inclined from the body portion 118a and protrudes in the axial direction to form a sharp hole. The tip portion 118b of the blade portion 118 is formed in accordance with the angle of the projecting portion on the bottom surface of the decorative body 26 mounted on the lens 12.

  In order to form the bottomed hole 28 in the lens 12, a jig 50 holding the glasses 10 in a predetermined posture is placed on the base 102 of the drilling machine 100. Then, the jig 50 is set at a predetermined position of the base 102, and as shown in FIG. In this case, by the operation of the handle 108 of the drilling machine 100 and the cooperative action of the vertical displacement means of the jig 50, the cavity 28a having a substantially constant diameter from the surface of the lens 12 and the diameter gradually decreasing from the cavity 28a. As a result, a bottomed hole 28 having a pointed bottom surface portion 28b is formed.

  As shown in FIG. 7, the bottomed hole 28 may be formed in the lens 12 using a cutting tool 120 having a diameter smaller than the diameter of the bottomed hole 28. In this case, by adjusting the position of the cutting tool 120 on the surface of the lens 12 and the amount of pushing of the cutting tool 120 at that position, the bottomed hole 28 having an arbitrary bottom shape can be formed. Therefore, the bottomed hole 28 can be formed according to the bottom shape of the various kinds of decorative bodies 26 without changing the cutting tool 120. Further, a laser may be used to form the bottomed hole 28 in the lens 12. By adjusting the position on the surface of the lens 12 and the depth of the bottomed hole 28 at that position using a laser, the bottomed hole 28 having an arbitrary bottom shape can be formed.

  By applying an adhesive to the bottom of the formed bottomed hole 28, an adhesive layer 30 is formed. Then, the decorative body 26 is fitted into the bottomed hole 28, and the bottom surface of the decorative body 26 is firmly fixed to the bottom surface of the bottomed hole 28 by the adhesive layer 30. At this time, the decorative body 26 is fixed to the lens 12 so as to slightly protrude from the surface of the lens 12. The amount of protrusion of the decorative body 26 from the surface of the lens 12 is set to be substantially the same as the depth of the hollow portion 28a formed on the surface side of the lens 12.

  Since the decorative body 26 used here is formed of crystal glass or the like, light incident on the decorative body 26 from the front surface side of the lens 12 is refracted in the decorative body 26 and emerges, thereby providing a beautiful appearance. It will have a shine. Therefore, by attaching the decorative body 26 to the lens 12, an excellent decorative effect can be obtained. At this time, when the decorative body 26 does not protrude from the surface of the lens 12 and is completely buried in the bottomed hole 28, the amount of light incident on the decorative body 26 decreases, and the brightness decreases. On the other hand, since a part of the decorative body 26 protrudes from the surface of the lens 12, light incident on the decorative body 26 increases, and a beautiful shine can be obtained.

  In the spectacles 10, since the bottom surface portion 28b of the bottomed hole 28 is formed in accordance with the bottom surface shape of the decorative body 26, the bottom surface of the decorative body 26 is arranged along the bottom surface of the bottomed hole 28. In this state, the decorative body 26 is fixed to the lens 12 by the adhesive layer 30, so that the decorative body 26 does not easily come off the lens 12. In addition, the wall surface of the hollow portion 28 a of the bottomed hole 28 surrounds the decoration 26, and the movement of the decoration 26 in the surface direction of the lens 12 is restricted. Therefore, for example, even when a force is applied to the protruding portion of the decorative body 26 when the lens 12 is wiped, the movement of the decorative body 26 is regulated by the wall surface of the hollow portion 28a, and the decorative body 26 is hardly detached from the lens 12. Become.

  Note that the decorative body 26 is not limited to crystal glass or the like, and natural jewelry or the like may be used. In particular, if the birthstone of the purchaser of the spectacles 10 is worn, the spectacles can be strongly connected to the purchaser. In addition to the natural birthstone, an imitation of a birthstone in which crystal glass is colored in the color of the birthstone may be attached to the lens 12.

  The arrangement of the decorative bodies 26 can be freely set. For example, as shown in FIG. 8, a plurality of decorative bodies 26 are arranged in a square shape, or as shown in FIG. 9, they are arranged in a cross shape. be able to. Further, the decorative body 26 can be arranged in a heart shape, and the arrangement shape can be freely set.

  Further, the decorative body 26 may be attached to a portion other than the lens 12. For example, as shown in FIG. 10, the decorative body 26 may be mounted on the temple 22, or as shown in FIG. 11, the decorative body 26 may be mounted on the front frame including the rim 16 and the wisdom 18. As described above, the decorative structure of the decorative body of the present invention is not limited to the lens 12, which is an optical component, but also tomo, bridge, temple, brace bar, blow bar A, blow bar B, rim, rim bar, eyebrows, eyebrows, and modern. And various non-optical components.

  When the decorative body 26 is mounted on the temple, the assembled glasses 10 are held in a predetermined posture by another jig 60 as shown in FIG. 12, for example. A groove 62 extending in the longitudinal direction is formed on a side surface of the jig 60. The jig 60 is supported by the shaft portion 64 so as to be vertically movable, similarly to the above-described jig 50.

  The eyeglasses 10 are fitted into the groove 62 with one temple 22 and the modern 24 arranged on the upper surface of the jig 60, and the other temple 22 and the modern 24 side bent at the hinge 20. In this case, the one temple 22 of the spectacles 10 is placed on the upper surface of the jig 60 so that the one temple 22 of the spectacles 10 is held by the jig 60 in an exposed state. Then, similarly to the case where the decorative body 26 is mounted on the lens 12, the bottomed hole 28 is formed in the temple 22, and the decorative body 26 is mounted.

  In this manner, the decorative body 26 can be attached to any part of the glasses 10 and can give the glasses 10 a beautiful appearance. Moreover, the decorative body 26 such as a multifaceted cut jewel or crystal glass can be fixed so as not to be detached from the spectacles 10, and by protruding a part of the decorative body 26, excellent shine can be provided.
