[Prior art]

 Traditionally known methods for decorating glass after glass cooling are cutting (cutting), etching, gravure, sand blasting and diamond point carving. Each technique has its own characteristics, and the one suitable for the pattern and design to be applied to glass is adopted. Gravure is a technique of engraving relief patterns and pictorial designs on the surface of glassware. FIG. 6 is a work state diagram showing an example of a decorating work for applying a pattern to the surface of a glassware by gravure. The glassware 50 is shown in a cross-sectional view in order to make it easier to understand the concave shape given by gravure. In this technique, a small-diameter copper disk 53 fixed to the tip of a rotary shaft 52 of a fixed rotary table 51, which is shown as a part, is attached with an abrasive 54 and rotated to form a glass surface 50 into a concave surface 55 having a predetermined shape. It is designed to be engraved. When the concave pattern portion 55 engraved on the surface of the glassware 50 is viewed in the direction of the arrow as shown in FIG. 7, light L transmitted from the back surface of the glassware 50 causes a pattern such as a pattern to have a convex shape. The visual effect of being visible is obtained.

[0003]

[Problems to be solved by the device]

 However, in the gravure, in order to form a pleated pattern on the relief, thin protrusions 56 and thin plate portions 57 are engraved on the surface of the glassware 50. Therefore, when the glassware 50 is handled, there is a possibility that a part of the protrusion 56 and the thin plate 57 may be chipped. In addition, in these works, patterns and designs are conventionally engraved on the surface of container-like shapes such as crystal glassware, so the design shape of the container and the patterns and designs applied on the surface are fused. It has been positioned as a thing. That is, conventionally, only a container made of glass having a light transmitting effect and a light reflecting effect was decorated and completed as an ornamental product or a practical product. There was no such thing as illuminating the sculpture pattern to make the relief shade and texture stand out.

Therefore, the object of the present invention is to solve the above-mentioned problems of the conventional technique, and to engrave a glass material such as a plate glass with a predetermined picture pattern, and to engrave the shadows and irregularities of the engraving. The objective is to provide picture-patterned sculptured glass with lighting so that it can stand out, and a frame case for display.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention illuminates a light-transmissive plate glass by illuminating light on the surface of a picture pattern which is formed by engraving the glass surface which is the back surface when viewed from the viewer side. The feature is that a shade effect is applied to the pattern.

Further, the picture engraving glass according to claim 1 is fixed to the front surface of the frame, and the light source stored in the case illuminates the picture surface of the picture engraving glass with illumination light. It is what

[0007]

[Action]

According to the present invention, the illumination light is applied to the surface of the light-transmissive plate glass, which is a concave-convex surface formed by engraving the glass surface that is the back surface when viewed from the viewer side, to illuminate the pattern. By applying the shading effect, the three-dimensional appearance and texture of the engraved uneven surface can be realistically represented.

Further, the picture engraving glass according to claim 1 is fixed to the front surface of the frame, and the light source stored in the case illuminates the picture surface of the picture engraving glass with illumination light. The relief effect of the picture engraving glass can be easily created.

【Example】

 Hereinafter, an embodiment of a picture engraving glass and a frame case for display according to the present invention will be described with reference to the accompanying drawings. FIG. 1 (a) is a perspective view showing an example of a picture pattern engraving glass. On the glass plate 10 shown in the figure, as an example, a pattern 11 with a figure of the upper body of a person is engraved in a relief pattern. The plate glass 10 is a normal standard plate glass. The sculpture is formed on the back side of the plate glass 10 when the viewer looks in the direction of the arrow by using various techniques as shown in FIG. Then, in the completed state, lighting is performed by the illumination 20 of a linear light source such as a fluorescent lamp from below the back side. By the light transmission effect of the glass portion and the light reflection effect of the glass surface by the illumination 20 arranged in this way, the three-dimensional effect and the shadow of the uneven surface provided on the thin plate material can be emphasized. In addition to the transparent plate glass, a light-transmitting colored plate glass or the like may be used.

Next, an example of the technique applied to the engraved surface will be described with reference to FIG. For the engraving, a known electric rotating tool used for ordinary glass engraving can be used. In addition to the disc-shaped router as shown in FIG. 6, various known cutting tools such as drill blades, drilling tools, and polishing tools can be attached to the tip attachment portion of the hand-held electric rotary tool. For example, it is efficient to use a disc-shaped router to form a wide concave portion. Inside the plate glass, there are cooling ripples caused by the glass composition during cooling. Since the cooling ripples are oriented as if they were wood grain in glass engraving, the finish of the cutting surface can be changed depending on how the cutting tool is applied. Normally, the cutting surface is a fine rough surface, so it is finished as a white and cloudy surface, but the reflection and refraction of illumination light differ depending on the depth of engraving and the angle formed by the cutting surface. Shows various aspects.

Among them, as a special technique, as shown in FIG. 2C, a smooth cut surface (smooth surface) 13 is formed on a part of a light-free cutting surface 12 made of a fine rough surface. It can also be made to shine partially. To make such a smooth surface 13, engrave the periphery 15 so that the projection 14 is left on the part to be finished as the smooth surface 13 as shown in FIG. Cut it into pieces to fold 14. Since the cross-sectional portion at that time is broken from the glass composition surface, a smooth surface can be obtained. This smooth surface 13 is slightly curved or distorted, so that light diffusely reflects and gives off a glittering shine.

FIG. 2 (e) is a technique suitable for representing an overlapping state such as a scale of fish or a fold of clothes. In order to form such an overlapped portion, as shown in FIG. 3D, the back side 17 is carved so that the overhanged portion 16 is formed so that the overlapped portion actually appears within a predetermined plate thickness range. Put in. Since the material is glass, which is a light-transmissive material, a portion where the overhang portions 16 overlap can be seen through, so that a three-dimensional effect can be realistically displayed.

In addition, a shallow engraving may be applied to the glass surface on the viewer side for a pattern engraved from the back side of the plate glass. This technique is suitable for subjects such as landscape painting. For example, by engraving the distant view deeply from the back side and adding the near view with a shallow sculpture like a line drawing on the front side, a part where the near view and the distant view overlap can be created, giving an effective depth feeling to the design. There is also a technique in which a plane mirror is used in place of the plate glass, the reflection surface side is engraved, and the formed concave surface portion is treated as a reflection surface. With such a mirror, it is possible to give the effect that the design is projected from the mirror surface portion. Furthermore, it is also possible to color the engraved rough surface. Since it is a rough surface, it can be colored with a watercolor paint, but various paints can be applied as long as they do not impair the light transmittance of the glass.

FIG. 3 is a schematic perspective view showing an example of a display frame case for housing and displaying the relief pattern engraved pictorial glass. The display frame case 30 according to the present embodiment is made of wood, and as shown in FIG. 4, a small fluorescent lamp (not shown) is housed inside. It goes without saying that metal materials such as synthetic resin and aluminum plate can be used for the case. The picture glass 10 is fixed to the front surface portion 31 of the frame from the inside through a frame 32, and the bottom plate 33 of the case 30 main body accommodates the fluorescent lamp 20 having the ballast 21. Further, a reflecting mirror 35 is housed and fixed on the lower surface of the top plate 34 and the inner surface of the side plate. The reflecting mirror 35 is arranged so as to form a predetermined angle with the top plate 34 via the pedestal 36, and when the fluorescent lamp 20 is attached, the pattern glass 10 attached to the front surface 31 of the frame can be illuminated from four directions. Has become. Further, a cloth 22 having a background color suitable for the design of the picture glass 10 is attached around the back plate 37 and the fluorescent lamp 20.

FIG. 5 is a partially enlarged view showing an application example of lighting. This figure shows a state in which a fluorescent lamp 25 as an auxiliary light source is housed inside a box-shaped side plate case 38. As shown in the figure, when the pattern glass 10 is illuminated from the side end face, the uneven portion receives the illumination light directly through the glass as compared with the case of lighting from the bottom plate position. The contrast is enhanced. Although a fluorescent lamp which is a linear light source is used as the light source in this embodiment, one or more light bulbs may be arranged to perform lighting. Needless to say, it is also possible to use natural light or external lighting.
