Description

  The present invention relates to a decorative shaped article using a light guide member.

  For example, as this type of decorative figurine, the one described in Patent Document 1 is known. As shown in FIG. 15, this decorative figurine includes a pseudo firefly light emitter 1 simulating a firefly form, a dedicated light source 2 for emitting light from the tail portion of the pseudo firefly light emitter 1, and a base end portion 3 a having a dedicated light source. 2 and the tip 3b is roughly constituted by an optical fiber 3 embedded in the body of the pseudo firefly light emitter 1, and a branch 4 of a pseudo plant that is wound around the optical fiber 3 with a tape. Here, the optical fiber 3 constitutes a trunk of a pseudo plant. In addition, natural leaves and leaves may be used. In this configuration, when the dedicated light source 2 is turned on, the light of the dedicated light source 2 that is guided to the optical fiber 3 and reaches the tail portion of the pseudo firefly light emitter 1 in the vicinity of the tip portion 3b of the optical fiber 3 and the vicinity of the tip portion It leaks to the outside of the pseudo firefly light emitter 1 from the side surface. According to this structure, it can be expected that the natural firefly that pertains to the branches and leaves of the plant gives a fantastic impression or presence as if it were actually emitting light from the tail.

JP 2006-244893 A

By the way, there are many animals, natural objects, buildings, or vehicles that are not accompanied by branches and leaves even if the branches and leaves of the plant are associated with the fireflies, so that the scope of application of the invention of Patent Document 1 is limited to decorative shaped objects. There is an inconvenience.
This is because if the invention of Patent Document 1 is applied to a decorative figurine that is poorly related to branches and leaves, a long optical fiber is configured to protrude from the figurine body, which is unfavorable. In order to conceal this unpleasantness, it is not natural to dispose an optical fiber on a branch plant because it is not a firefly.
Moreover, the optical fiber extended outside from the characteristic part of the figurine main body is an obstacle and inconvenient when the decorative figurine is installed and transported. In addition, there is a possibility that the optical fiber extending outward from the characteristic part of the figurine body may be damaged by careless handling.

  On the other hand, in the conventional glass figurine that imitates an animal, a pattern and a characteristic part are often expressed by opaque colored glass. For example, in the glass figurine 5 imitating an owl shown in FIG. It is formed. In addition, colored glass of various colors is also used when expressing the flower core of a plant. This kind of glass figurine, like other items, has a yin yang feeling (brightness and shading) appropriate to the changes in the brightness of ambient lighting, the intensity of natural light, and the direction of the arrival of light. Can do. However, it is a yin and yang feeling as a whole glass figurine, and typical characteristic parts such as the eyes do not have a very yin and yang feeling compared to the surrounding parts. Therefore, this kind of glass figurine has the aesthetic limit that it has poor variability in aesthetics.

  This invention is made in view of the above-mentioned circumstances, and is a decorative modeling using a light guide member that can create the beauty of a model according to the brightness and arrival direction of external light including indoor illumination light and natural light. The purpose is to provide goods.

  In order to solve the above-described problems, the structure of the present invention includes a single translucent or semi-transparent molded article having a contour shape simulating an imaginary or real animal or a portion thereof as an eye light-emitting element of the animal. Or, the present invention relates to a decorative shaped article to which a plurality of translucent light guide members are attached, and the light guide member picks up incident light or natural light that illuminates all or part of the room from one end side thereof. The incident illumination light or natural light is emitted from the other end into the molded body again as an impression light that enhances the impression of the animal's eyes or a display light that expresses the eyes of the animal. It is characterized by being completely or partially embedded.

  According to the configuration of the present invention, it is possible to dynamically change the aesthetics according to the brightness and direction of arrival of external light including ambient illumination light and natural light (positional orientation relationship between the decorative shaped object of the present invention and the light source). it can. In addition, since the light guide member is embedded in the decorative molded article, the appearance beauty of the decorative molded article is not impaired, and handling during installation and transportation is easy. Moreover, since a dedicated light source is not required, it is preferable in terms of power saving.

In this specification, the decorative modeled object is not limited to a complete three-dimensional modeled object, but is a concept that includes a plate-shaped modeled object as well as a relief-shaped modeled object. Further, a modeled object in which an animal or the like is imitated as a part of the whole is also a decorative modeled object that is an object of the present invention.

Embodiment 1

Hereinafter, preferred embodiments of the present invention will be described with reference examples .
The decorative shaped object according to the embodiment and the reference example of the present invention imitates an imaginary or real animal, plant, natural object, building, or vehicle (hereinafter simply referred to as an animal) having a predetermined characteristic part. A translucent or semi-translucent molded body (hereinafter simply referred to as a transparent molded body) and a predetermined curve as a light emitting element for enhancing the aesthetics of a characteristic part such as an animal. It is comprised roughly from the one or several light guide member embed | buried drawing the path | route. The light guide member includes a light incident end face for allowing light from the outside to enter, a light guide part for forming a predetermined curved path, and a light emitting part for emitting impression light. It is preferably embedded in the body of the molded body without protruding from the contour surface. In addition, as an exception, even if a part of the light guide member is exposed or protrudes from the surface of the molded body, when this exposed or protruding part constitutes a part of the decorative molded article, this exposure or protrusion The portion is not an extraneous object that impairs the aesthetic appearance of the decorative shaped object, but is a product that produces aesthetics, and is within the scope of the present invention.

In the interior of the decorative shaped article, the light incident end face of the light guide member is arranged at a part that easily takes in external light (for example, upward or downward), and the light emitting part is arranged as a component of a predetermined characteristic part such as an animal. Alternatively, it is arranged at a position where the characteristic part can be illuminated from the inside. When the position and direction of the light incident end face and the light emitting part are specified, the length and the curve shape of the light guide part are determined.
In the above configuration, the external light incident from the light incident end face is guided to the light guide part, and the impression light (design light) that aesthetically impresses the predetermined characteristic part of the decorative shaped object imitating an animal or the like from the light emitting part. Alternatively, it is emitted to the outside as display marker light that enhances the display marker function. Here, the light emitting portion is not limited to the end face from which light is emitted, but also includes a side surface that emits desired light (having a predetermined length) according to a demand for aesthetic functions.

  Here, the “characteristic portion” refers to an appearance portion that a person who creates a decorative shaped object wants to express among portions inherently or inherently provided by an animal or the like. An animal eye or a flower part of a plant can be cited as a suitable characteristic part, but is not limited thereto. For example, animal corners, fur and feather patterns, plant stems, ears and leaves can be characteristic parts.

In addition, the external light includes, for example, natural light and illumination light from various light sources such as indoor lighting, but is not limited thereto, and includes, for example, reflected light from a secondary light source such as a mirror body . Also, depending on the aesthetic expression you want to realize, you can change the structure and arrangement of the light guide member, especially the light incident end face and light emitting part, so that, for example, the outline has a clear glow, Various shines (impression light, functional light) such as shine and dazzling shine can be realized, and the radiance can be diverged or gradation can be given.

  The light incident end face of the light guide member is not always arranged to face upward, but is preferably arranged in the direction of arrival of external light as much as possible. Similarly, it is preferable that the light emitting end face is arranged toward the viewer side in consideration of the viewer's line of sight and viewing direction. In general, since the direction of arrival of external light is different from the visually recognized direction, in principle, the optical axis direction of the light incident end face of the light guide member does not match the optical axis direction of the light outgoing end face. If the light incident end face and the light exit end face of the light guide member are arranged as described above, the article color of the decorative shaped object (an object that stimulates the human retina by the light reflected and scattered from the surface of the received external light) Characteristics) and transmitted light from the back side that passes through the front side, and a much brighter impression light can be emitted from the light exit end face. Can shine.

  Here, if the transparent molded body and the light guide member are both transparent, the light guide member embedded in the transparent molded body cannot be easily identified from the transparent molded body, so that the transparent aesthetics of the decorative molded article is impaired. There is no. However, for example, the refractive index difference between the transparent molded body and the light guide member is made as small as possible, the surface of the transparent molded body is made a frosted surface, an uneven surface, a lens surface, or a wave surface, or is colored or patterned. If it is devised, the transparent aesthetics of the decorative shaped object can be further enhanced. In this way, the isolated shine of the feature portion, which is different from the shine due to light reflection at the feature portion, causes a mysterious aesthetic to the viewer. The refractive index difference between the transparent molded body and the light guide member (core part) is arbitrary, but is preferably set to 0.4 or less, and more preferably 0.2 or less. Further, an antireflection film may be applied to the light guide member.

  Further, as a preferable light guide member, a step index type optical fiber or a graded index type optical fiber, or a side emission type optical fiber having one or a plurality of light emitting portions (light emitting side surfaces) on the side surface is used. It can mention, but it is not limited to these. For example, instead of a normal optical fiber consisting of a core part and a clad part, an optical fiber consisting only of a core part having a refractive index higher than that of the molded material may be used. Moreover, as long as it functions as an aesthetic light guide member, instead of the optical fiber, for example, a flat waveguide may be used, and a wave plate or various curved plate waveguides may be used.

  Examples of the material for the transparent molded body include, but are not limited to, known various glass materials and various plastic materials including low melting point glass and crystal glass. Similarly, as the light guide member (optical fiber), well-known various glass materials and various plastic materials can be preferably exemplified, but not limited thereto. Here, the combination of the material of the transparent molded body and the light guide member is not limited to a combination of homogeneous materials, and may be a combination of different materials. However, in any combination, the light guide member has a high melting point or softening point (at least in the core portion) relative to the material of the transparent molded body so that the light guide member does not melt and break in the molten transparent molded body. Is preferably used.

  Here, if a glass optical fiber is used as the light guide member, for example, an optical fiber having a thickness of 10 μm to 10 mm may be bundled in a predetermined cross-sectional shape to obtain a light emitting end face. A single line may be used. On the other hand, if a plastic optical fiber is used as the light guide member, for example, a single wire having a thickness of 50 μm to 20 mm can be preferably used, but if necessary, it is bundled into a predetermined cross-sectional shape. You can also In addition, in order to obtain a predetermined cross-sectional shape, a configuration in which a plurality of optical fibers (single lines) are bundled only on the light emitting end face side, while on the light incident end face side, in order to collect external light coming from different directions, Instead of bundling a plurality of optical fibers (single line), the individual optical fibers may be directed in different directions. In addition, in order to realize various aesthetic expressions, the light exit end face of the light guide member (optical fiber) is dotted, granular, true circular, semicircular, elliptical, semielliptical, rectangular, triangular, cylindrical, The shape may be a star shape or a three-month shape, and the shape may be irregular and disordered.

The decorative shaped object of this embodiment is produced as follows, for example.
First, a desired curve shape (for example, a C shape or an L shape) is given to an optical fiber having a predetermined size to create a light guide member. Here, since it is difficult to bend the light guide portion because the light guide member has a large diameter, it is easy to bend the cross-sectional shape of the curved portion having a large curvature smaller than that of other portions. It should be noted that both end faces of the light guide member (optical fiber) are preferably polished in advance. Next, the pair of right and left light guide members are arranged in a space region in which a predetermined characteristic part is formed in a mold for forming a decorative shaped article. Specifically, the light incident end face of the light guide member is arranged at a predetermined position in the spatial region in the direction of the expected external light arrival, and the light emitting surface is arranged in a predetermined region in the spatial region. It arrange | positions in the characteristic part formation area | region or its vicinity.

  Here, in order to stably arrange the pair of right and left light guide members in the space region, a transparent bond of the same quality as the transparent molding material (or higher melting point or softening point than that of the transparent molding material). Using a member, the pair of right and left light guide members may be fixed in such a manner that the positional relationship and the overall appearance are maintained, and thereafter, the whole coupling member may be disposed in the mold. In that case, you may make it give a function to arrange | position a pair of light guide members stably in a metal mold | die in a coupling member. Next, a melted or softened transparent molded material (glass or plastic) is injected and filled into the mold. In addition, when injecting and filling the material of the transparent molded body in a molten or softened state into the mold, the light guide member is used as the melting temperature or softening temperature of the material of the transparent molded body or a temperature in the vicinity thereof (when using a bonding member). Is preferably preheated to a temperature at which the coupling member does not melt or soften. Thereafter, when the transparent molded body in the mold is cooled, the integrally molded decorative article with the light guide member (and the coupling member) embedded therein is completed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a schematic configuration and an external shape of a decorative shaped article (owl figurine) including a light guide light emitting element according to a first embodiment of the present invention.

Each optical fiber 9 includes a light incident end face 9a arranged in an upper or obliquely upward manner within the upper head of the owl figurine 7, a light guide portion 9b curved in a C shape or an L shape, and an owl. It is comprised from the light emission end surface 9c arrange | positioned at the site | part of the pupil 10 which is the characteristic site | part of the figurine 7 (the figure (a)). The shape of the optical fiber is not limited to the C shape or the L shape, and may be any curved shape as long as it extends from the upper head of the owl figurine 7 to the portion of the pupil 10 of the front face. Moreover, the site | part in which the light-incidence end surface 9a is arrange | positioned is not restricted to the upper head of the owl figurine 7, but is arbitrary as long as it is a site | part which can take in external light Li.
In this example, the light emission end face 9c is arranged inside the outline of the pupil 10 projecting in a hemispherical shape so as to face the front of the front face portion of the owl figurine 7, and constitutes a part of the pupil 10. . The hemispherical pupil 10 has a function of diverging the impression light Lo by the lens action, widening the viewing angle, and making the pupil 10 look larger.

  According to the above configuration, the external light Li incident from the light incident end surface 9a is guided to the light guide portion 9b and is emitted again as the impression light Lo from the light emitting end surface 9c, which may cause aesthetics to the viewer. it can. In addition, the viewer can see the brightness Lo of the pupil 10 of the owl figurine 7 from the front side of the owl figurine 7, but since the owl figurine 7 is a transparent body, the shine Lo cannot be seen from behind. It can cause a strange aesthetic to the viewer. The reason is that the light emission end face 9c faces the front side outward of the owl figurine 7, so that the impression light Lo is emitted from the light emission end face 9c outwardly from the front side. The light is reflected by the light emitting end face 9c and travels to the rear side. However, the light toward the rear side does not escape to the back surface side of the owl object 7 and returns to the light incident end surface 9a via the light guide portion 9b due to the waveguide characteristic of the optical fiber 9.

And a tapered light emitting portion having a hemispherical or substantially spherical convex curved surface and a wide-mouth light emitting end face 13c. The light emitting end face 13c of this example constitutes the surface contour of the owl figurine 11 as shown in FIG.

In this embodiment, the light incident end face 13a is an aspect facing upward on the upper head of the transparent molded body 12, and the light exit end face 13c is an aspect forming the contour surface of the pupil 14 on the face front of the transparent molded body 12, respectively. Has been placed.
According to the configuration of this example, since the light incident end face 13a has a wide opening, the incident amount of the external light Li can be increased, and thus the pupil 14 of the owl figurine 11 can be made to shine more strongly. In addition, since the light emission end face 13c is hemispherical or substantially spherical, the impression light Lo can be diffused, and therefore the pupil 14 of the owl figurine 11 can be made to shine greatly. If the cross-sectional area of the light incident end face is made larger than that of the light exit end face, the luminance of the pupil 14 can be further increased. Further, the light incident end surface 13a is not limited to a flat surface, and may be a curved lens surface.

Thus, the light incident end face 56a (optical fiber base end) is disposed downward in the body of the pedestal 57, and the light exit end face 56c (optical fiber distal end) is disposed on the hemispherical or substantially spherical flower core S. The impression light Lo is emitted. Note that the light emitting end face 56c itself may constitute the hemispherical or substantially spherical floral core S or a part thereof.

  In addition, if a side-emission type optical fiber is used as the optical fiber 56 so that light leaks from the flower axis K, a different aesthetics can be caused. In addition, a detachable planting hole may be provided in the pedestal 57 so that the number of flowers can be increased or decreased as necessary. Since the light incident part 56a is arranged downward, the flower object 54 is preferably placed on a light-transmitting placing table that receives illumination light from the back side.

Reference Example 6

FIG. 12: is a perspective view which shows schematic structure of the decorative molded article (strawberry figurine) provided with the light guide light emitting element which is the 6th reference example of this invention.
The strawberry figurine 58 in this example is composed of a transparent molded body 59 that imitates a strawberry and a large number of U-shaped fine optical fibers 60 that are randomly embedded in the transparent molded body 59 (same as above). Figure (a)). The light guide portion 60b of this example plays a role as a bidirectional optical transmission line, and both end faces of each optical fiber 60 are arranged outward as light incident / exit end faces 60a and 60c, A light spot of the crushed pattern 61 is formed ((b) in the figure).

FIG. 13: is a perspective view which shows schematic structure of the decorative molded article (snail figurine) provided with the light guide light emitting element which is the 7th Example of this invention.
As shown in FIG. 13, this snail figurine 62 is composed of a transparent molded body 63 simulating a snail and a pair of left and right optical fibers 64 embedded as aesthetic light emitting elements in the body of the transparent molded body 63. . Each optical fiber 64 includes a light incident end face 64a, a light guide portion 64b, and a light exit end face 64c, and guides the external light Li received by the back of the snail (light incident end face 64a) to the centerpiece 65. Then, the impression light Lo is emitted from the light incident end face 64a to shine the eyeball 65 that has come out in a match shape of the snail figurine.

  In this example, as shown in FIG. 13, the distal end shaft portion 64d of the light guide portion 64b jumps out of the transparent molded body 63 to form a match-like eye 66 of the snail figurine to constitute an aesthetic appearance. In this case, the distal end shaft portion 64d of the light guide portion 64b protrudes from the transparent molded body 63, and is not an extraneous object that impairs the aesthetic appearance. The difference between the snail figurine 62 in FIG. 13A and the snail figurine 67 in FIG. 13B is only in the direction of receiving the external light Li.

FIG. 14: is a perspective view which shows schematic structure of the decorative molded article (owl figurine) provided with the light guide light emitting element which is the 8th Example of this invention.
The owl figurine 68 in this example includes a transparent molded body 69 simulating an owl, and a ring-shaped optical fiber 70 embedded as an aesthetic light emitting element in the head of the transparent molded body 69. The ring-shaped optical fiber 70 is formed, for example, by covering the outer periphery of a transparent core material 71 made of glass (or plastic) with a thin optical fiber bundle 72, and a light incident end face 70 a, for example, C-shaped or Both the light guide portion 70b curved in an L shape and the light emitting end surface 70c are formed in a ring shape.

  According to the configuration of this example, since the impression light Lo is emitted from the annular light emitting end face 70c, it is possible to obtain an aesthetic appearance in which the pupil 10C shines in an annular shape. In addition, the shape of the annular optical fiber 70 is not limited to a circle, an ellipse, or a polygon, but may be a semicircle or a semi-ellipse. In short, any shape can be used as long as an aesthetic appearance can be expressed. Further, a portion of the pupil corresponding to the central portion of the annular light emitting end face 70c may be colored 73 as shown in FIG.

The embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to the embodiments, and there are design changes and the like without departing from the gist of the present invention. Are also included in the present invention. For example, the present invention is not limited to decorative figurines but can be applied to decorative wall hangings. Further, the part other than the predetermined characteristic part and the light incident end face (for example, a pedestal or the like) or the contour surface may be made of a light-impermeable material, and may be a light-impermeable contour surface by a colorant. May be. Further, the present invention is not limited to an integrally molded decorative article.

  The present invention is not limited to decorative ornaments, and can be applied to, for example, wall hangings, strap charms, decorative magnets, and the like, and can also be applied to decorative shaped objects having a display function, for example.
