Description

  The present invention relates to a figurine having a transparent glass structure engraved with a three-dimensional image and a light-shielding back member, which is less susceptible to light reflection and makes it easier to see a three-dimensional image from the front.

  A technique for drawing inside a glass with a laser is known, and an ornament that makes a drawn stereoscopic image visible from the outside is also known.

Patent Document 1 discloses a technique for forming an image by scanning a laser beam while controlling the position of the laser beam and forming a fine crack in a dot shape at the focal point by focusing on a desired position inside the crystal glass. Are listed.
However, this makes it easy to see by defining the angle of the image plane with respect to the “viewing surface of the crystal glass”, and the technique described in Patent Document 1 applies a planar image to a desired plane inside the crystal glass. It was formed.

Patent Document 2 describes a workpiece having a thermally deteriorated layer in which compressive stress is accumulated by irradiating condensed laser light.
However, this technique is not particularly applied to figurines, and it has not been easy to visually recognize an image (stereoscopic image) formed inside.

  Patent Document 3 describes a tombstone in which a three-dimensional image is laser-processed inside a crystal glass. However, the three-dimensional image is not particularly easy to see from the outside.

Further, Patent Document 4 includes an ornament having an inclined side surface and a top surface formed so as to form an image by laser processing the inside, process the back surface in black or dark color, and spread from the back surface toward the front surface. Are listed. This technique blocks the incident light from the back side to increase the contrast of the image, and can take in more external light than a rectangular parallelepiped, so that the image can be seen brighter.
However, the light from the outside is reflected on the front of the figurine, and it is difficult to see the image, and the side of the figurine is suppressed from being difficult to see due to the reflection of light from the inside of the crystal glass to the outside. However, it was not enough for the visibility of the images.

  The present invention has been made in view of the above-mentioned background art, and its problem is that it eliminates the reflection of a virtual image due to reflection on various surfaces and makes it difficult to see a stereoscopic image by incident light from various directions. An object of the present invention is to provide a figurine that is suppressed and has a beautiful appearance, and in which a three-dimensional image is engraved.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor made a transparent material by making the back, side, and front of the figurine a material or form having specific physical properties or setting a specific angle. The inventors found that the three-dimensional image engraved inside the glass structure is very easy to see from the front, and completed the present invention.

That is, the present invention is a figurine having a transparent glass structure engraved with a three-dimensional image inside, and a light-shielding back member on the entire back surface of the transparent glass structure,
The transparent glass structure is one in which the stereoscopic image is engraved in the transparent glass structure by focusing the laser beam inside the transparent glass structure and moving the position of the focus.
The light-shielding back member has an extinction coefficient and a thickness such that the transmittance of the entire visible light is 1% or less so that the stereoscopic image can be easily seen from the front surface of the figurine,
The side surface of the transparent glass structure is a matte surface, the front surface of the transparent glass structure is a smooth surface, and the inclination angle formed by the front surface and the bottom surface of the transparent glass structure is 60 ° or more and 85 °. The present invention provides an ornament characterized by the following.

  According to the present invention, the above-mentioned problems and the above-mentioned problems are solved, and an external object is not reflected on the front surface of the transparent glass structure when viewed from the normal front direction. A stereoscopic image is not reflected when viewed from the inside of the structure, and an external object is not reflected on the side surface of the transparent glass structure when viewed from the lateral direction.

In addition, since the entire back surface of the transparent glass structure has a light-shielding back member having a low transmittance for the entire visible light, it is markedly less than when a thin colored transparent or colorless transparent back member is used or when there is no back member. In addition, a three-dimensional image engraved inside the transparent glass structure becomes easy to see and stands out.
Further, by making the light-shielding back member black, dark red, dark blue, dark yellow or dark pink, the reflected light is also limited, compared to the case where the back is made of a light-colored member, As a result, the internal stereoscopic image becomes easier to see and stands out.

  In addition, since the side surface of the transparent glass structure is a matte surface, reflection from the outside to the inside and from the inside to the outside can be suppressed, and since it is a matte surface, light from the side surface is transmitted. Therefore, the three-dimensional image engraved inside the transparent glass structure is easy to see from the front and stands out.

  By focusing the laser beam inside the transparent glass structure and moving the position of the focus, the three-dimensional image engraved inside cannot be colored and is a collection of white minute dots. There is only a method for making a three-dimensional image easy to see and enhance only by improving the transmission of light and suppressing the reflection, and thus the above-described effect is extremely remarkable.

Moreover, if the upper surface of the transparent glass structure is a smooth surface and a convex lens surface, a presbyopic can be used instead of glasses by placing the figurine of the present invention on an object to be seen.
Moreover, in addition to the three-dimensional image inside the transparent glass structure, the appearance of the figurine itself is also beautiful, making it an excellent figurine.

It is a perspective view of an example of the figurine of the present invention. It is a side view of an example of the figurine of the present invention.
