Description

  The present invention particularly relates to a glass craft suitable for a glass lamp or the like in which a light source is housed.

Conventionally, glass crafts represented by vases, figurines, and the like use a plurality of colored glasses (so-called colored glass) to form a three-dimensional work. This is basically a technique in which colored glass is placed at a desired position on the base glass substrate, placed in a furnace, melted and welded, and is sufficient to integrate the colored glass with the glass substrate. On the other hand, when the melting temperature is too high, the glass melts to such a degree that it cannot maintain the regularity, and the work is greatly deformed. Therefore, the production process has a very high skill.
The technique of such glass crafts has been handed down from the 19th century and is a well-known technique, but one example of recent improvement techniques is shown in Technical Document 1.
Japanese Patent Laid-Open No. 2001-240431

However, as described above, the technique of stacking a plurality of colored glasses requires a very high level of skill, so it often does not necessarily finish a work as designed. In addition, since the glass piece has to be heated with a delicate heating as described above, it is difficult to cope with a fine design. For this reason, glass crafts that combine colored glass that more accurately reflects the design of the designer have been demanded. In particular, in a glass lamp, a lamp that transmits light by placing a light source inside and the light that has passed through the lamp itself are subject to appreciation. Therefore, not only the shape and position of the colored glass but also the thickness of the colored glass in the designer There is a request to finely adjust (because it has an important effect on the transmittance). However, as described above, it has been impossible for the conventional technique to satisfy such a fine designer's request.
The present invention has been made by paying attention to such problems existing in the prior art. The object is to provide glass crafts and glass lamps that do not require a high level of skill and can reflect the design of the designer very faithfully.

As a first means for achieving the above-mentioned object, a glass in a semi-fluid state in which a colorant is added is applied to the outer surface of a glass substrate, and the plastic is cured to form an outer skin layer. Like to get.
With such a structure, a glass-like three-dimensional outer skin layer is formed by a plastic colored by adding a colorant, and it is as if the colored glass was used without fusing the molten colored glass to the glass substrate. This makes it possible to produce a three-dimensional glass craft. Such plastics do not require much skill compared to melting conventional glass. Specifically, there is no need for detailed contact / separation operation for the work (glass) fire in the furnace when the colored glass is welded to the glass substrate, and a desired outer skin layer is formed with sufficient time. Therefore, it becomes possible to obtain a glass craft with a more precise design.
Here, the plastic may be either a thermoplastic or a thermosetting material as long as it temporarily becomes a fluid and solidifies at room temperature. However, since it is important to not deform after production, it is more preferable to use a thermosetting plastic that does not semi-flow again even if reheated by cross-linking from a fluidized state and curing. The thermosetting plastic is a concept including a room temperature curing type epoxy resin. Examples of the plastic suitable for the present invention include thermosetting plastics such as epoxy resins, melamine resins, and urea resins. Of these, a room temperature curable thermosetting plastic such as an epoxy resin is most preferable in view of workability. Examples of the thermoplastic plastic include polyethylene, polypropylene, and polyester elastomer (TPEE). However, most preferred are epoxy resins that can be used at room temperature.
“Semi-fluid” refers to a fluid that is viscous to the extent that it does not flow down easily even when applied to a vertical wall surface, for example.
As the colorant, paints, pigments and the like can be widely used, and are not particularly limited. However, when reacting with the plastic used, it is necessary to consider the color after the reaction. For example, if an epoxy resin that can be used at room temperature is used, it is also possible to use a colorant that could not be used for a colored glass that may be heat-modified.

In the second means, in addition to the first means, the outer skin layer has translucency.
With this configuration, the outer skin layer has a more glass-like appearance, and it is preferable to form the outer skin layer using a plastic having such properties for glass crafts that need to be translucent. .
In the third means, in addition to the first or second means, a metal foil is attached to the outer surface of the glass substrate, and an outer skin layer is formed by applying the metal foil onto the plastic substrate from the plastic same metal foil. I try to do it.
With this configuration, the metal foil is visually observed through the outer skin layer, and the appearance is superior to the case where the outer skin layer is simply formed on the outer surface of the glass substrate. Further, since the metal foil can be arranged with a time margin as compared with the conventional technique, it becomes possible to produce a glass craft with a more precise design.

In a fourth means, a light source is housed inside a transparent glass substrate, and a glass lamp that illuminates the surroundings through the glass has a translucency with a colorant added to the outer surface of the glass substrate. A state-of-the-art plastic is applied and the plastic is cured to form an outer skin layer to obtain a glass lamp.
With such a structure, a glass-like three-dimensional and transparent outer skin layer is formed by a plastic that is colored by adding a colorant, and the colored glass is used without welding the molten colored glass to the glass substrate. It is possible to produce a glass lamp with such a three-dimensional feeling, and the outer skin layer colored in a desired thickness and color is illuminated by the light from the light source, and the light transmitted through the outer skin layer Illuminate the surroundings.
This makes it possible to produce a glass lamp that reflects the designer's design very faithfully. In addition, it does not require detailed contact / separation operations for the work (glass) fire in the furnace when the colored glass is welded to the glass substrate as in the case of melting conventional glass, and it takes time to afford. Since a desired outer skin layer can be formed, it is possible to obtain a glass lamp with a more precise design.
The definitions of “colorant” and “semi-fluid” in the fourth means are the same as those in the first means. The definition of “plastic” must be translucent in terms of the properties of the product. Further, “transparent” is a concept including translucency other than colorless and transparent.

In the fifth means, in addition to the fourth means, a contour line of a sketch is engraved on the outer surface of the glass substrate, and the plastic layer is individually applied to each sketch region defined by the contour line. Try to form.
In the conventional technique of welding colored glass, even if the outline of the sketch is engraved on the glass substrate, it is technically very difficult to weld the colored glass according to the outline, and the colored glass is deformed by heat. Actually, it was impossible to reproduce the design so accurately that it was necessary to engrave the outline. However, if it is possible to apply the semi-fluid plastic little by little with sufficient time, it can be arranged along the outline of the sketch. Therefore, the merit of engraving the outline for the first time in the present invention is created.
In the sixth means, in addition to the fourth means, a sketch cut into a concave shape by cutting or grinding is formed on the outer surface of the glass substrate, and the plastic is individually applied to each of the sketch areas. To form.
The portion of the glass substrate that has been scraped off in a concave shape has improved translucency as the glass becomes thinner. That is, it is possible to change the transmissivity according to the concave depth. By individually applying plastic to each such background area, it is possible to set the light transmittance of that portion and the color tone due to light transmission as desired by the designer.

In the seventh means, in addition to the fourth to sixth means, the glass base is composed of a body that stores liquid fuel, and a cap body that is configured separately from the body and installed on the body. The fuselage is provided with a top plate portion for supporting the lamp core by suspending it at the top. The burning portion of the wick is placed in the same casing body through the same through hole, while the outer skin layer is not formed at the same top plate portion position and the same bottom plate portion position. Yes.
As a result, the light from the burning part of the wick, which is the light source position, reaches the top plate at the top of the fuselage from the bottom plate of the shade without being shielded by the outer skin layer, and can illuminate the fuselage.
In the eighth means, in addition to the seventh means, a metal foil is attached to the outer surface of the wall surface of the cap body, and the plastic is applied onto the glass substrate from the metal foil to form an outer skin layer. I am doing so.
Thus, light is reflected by the metal foil on the wall surface of the shade body. At that time, a part of the light reaches the top plate at the top of the fuselage from the bottom plate of the shade body, and can illuminate the fuselage.

According to the inventions of the first to third aspects, it is possible to produce a glass craft having a three-dimensional effect as if the colored glass was used without welding the molten colored glass to the glass substrate. In addition, the plastics that make up the outer skin layer do not require much skill compared to the conventional case of melting glass, and the producer can carefully form the desired outer skin layer with sufficient time. Therefore, it becomes possible to obtain a glass craft with a more elaborate design.
Further, according to the above-mentioned inventions of claims 4 to 8, it is possible to produce a glass lamp having a three-dimensional effect as if the colored glass was used without welding the molten colored glass to the glass substrate. In addition, the plastics that make up the outer skin layer do not require much skill compared to the case of melting conventional glass, and the producer can carefully form the desired outer skin layer with sufficient time. Therefore, it becomes possible to obtain a glass lamp with a more precise design. Furthermore, the outer skin layer colored to the desired thickness and color can be illuminated by light from the light source, and the surroundings can be illuminated by the light transmitted through such outer skin layer, so compared to conventional glass lamps This broadens the range of designer designs and increases the willingness to create glass lamps.

Hereinafter, an embodiment in which a glass lamp which is a kind of glass craftwork in the present invention is embodied will be described with reference to the drawings.
As shown in FIG. 1, a glass lamp 1 according to the present embodiment includes a body 2 and a shade body 3 as glass substrates. The body 2 and the shade body 3 are made of colorless and transparent glass.
The body 2 includes a circular bottom plate portion 5, and a peripheral wall 6 is erected upward from the entire periphery of the bottom plate portion 5. The thickness of the peripheral wall 6 is uniform throughout. The peripheral wall 6 is formed in a taper shape with a larger radial cross section as it extends upward. In other words, the shape is expanded toward the upper side. The housing portion 7 is formed inside by the first bottom plate portion 5 and the peripheral wall 6. A projecting leg portion 8 is formed in a ring shape on the outer periphery of the first bottom plate portion 5. The body 2 is supported on the overhanging leg portion 8 and installed on the installation surface.
A circular top plate portion 9 is formed on the upper portion of the peripheral wall 6. The entire peripheral edge of the top plate portion 9 is integrated with the peripheral wall 6. A through hole 10 is formed in the center of the top plate portion 9. That is, the trunk | drum 2 will connect the accommodating part 7 and external air only in the through-hole 10. FIG. The entire periphery of the through hole 10 in the top plate portion 9 rises upward to form a cap support portion 11.

In the body 2 configured as described above, a first skin layer 13 is formed on the entire outer surface (that is, the side surface) of the peripheral wall 6 and the entire outer surface (that is, the upper surface) of the overhanging leg portion 8. In the present embodiment, the outer skin layer 13 is configured by superimposing a plurality of single outer layers 14 each having a different color tone. The single outer layer 14 is formed by applying and curing a plurality of types of semi-fluid coating materials having different color tones mixed with a plurality of types of rock paints (pigments) at desired positions. In the present embodiment, the coating material for the outer skin is prepared from a plastic raw material mainly composed of an epoxy resin. Therefore, the single outer layer 14 has a transparent glass-like appearance, and has translucency depending on the mixing ratio of the rock paint and the thickness of the applied layer. This single outer layer 14 corresponds to a conventional colored glass.
A cap 15 for a wick is attached to the cap support 11 formed on the top plate 9 of the body 2. The upper portion of the long lamp core 16 is held by the lamp core cap 15, and the lamp core 16 is suspended in the housing portion 7. A part of the lamp core 16 held by the core cap 15 and exposed upward is used as a combustion portion 16a.

The shade body 3 includes an inclined wall portion 17 configured in a ring shape that is inclined so as to descend from the center toward the outer periphery, and a second bottom plate portion 18 that seals a lower region surrounded by the inclined wall portion 17. ing. The thickness of the inclined wall portion 17 is made uniform throughout the entire area before grinding which will be described later. The thickness of the second bottom plate portion 18 is uniform over the entire area. A circular opening 19 is formed at the upper edge of the inclined wall portion 17. A through hole 21 is formed in the center of the second bottom plate portion 18, and a small cylindrical portion 22 projects from the through hole 21 downward. The inner diameter of the small cylindrical portion 22 is slightly larger than the outer shape of the cap support portion 11 so as to surround the cap support portion 11.
As shown in FIGS. 1, 2, and 4, a second skin layer 25 is formed on the outer surface of the inclined wall portion 17. In the outer skin layer 25 of the present embodiment, a plurality of single outer layers 26 having different color tones are arranged so as to individually draw a pattern in a predetermined region. Similarly to the above, the single outer layer 26 is formed by applying a plurality of types of semi-fluid coating materials in different colors, mixed with a plurality of types of rock paints (pigments), and curing them.
In the outer skin layer 25 in the present embodiment, a pattern in which a plurality of flower patterns 27 are arranged adjacent to each other in a ring shape is drawn in a relief shape. These flower patterns 27 are composed of three parts, a flower core, a petal, a cocoon leaf, and a cocoon leaf, and are composed of first to third single outer layers 26a to 26c, respectively. The outer skin layer 25 is composed of these three kinds of single outer layers 26a to 26c having different color tones and a fourth single outer layer 26d that fills the outer surface of the inclined wall portion 17 other than the flower pattern 27 portion. As shown in FIG. 3, a gold foil 31 is disposed between the fourth single outer layer 26 d near the outer periphery of the inclined wall portion 17 and the inclined wall portion 17.

As shown in FIGS. 3A and 3B, a plurality of concave portions 33 are formed on the outer surface of the inclined wall portion 17 by grinding. As shown in FIG. 3B, the concave portion 33 as a background region is formed at the positions of the first to third single outer layers 26 a to 26 c that draw the flower pattern 27. In the present embodiment, the depth of the recess 33 is not uniform because the amount of light transmitted by the parts of the flower pattern 27 is changed. In this embodiment, the concave portion 33a (flower core position) where the first single outer layer 26a is formed is the shallowest, and the concave portion 33b (petal position) where the second single outer layer 26b is formed is the deepest. As shown in FIG. 4B, a large amount of outer coating material is applied to the deeply formed concave portion 33, and a small amount of outer coating material is applied to the shallow concave portion 33. From the side, the surface of the flower pattern 27 is visually observed on a substantially uniform surface that is not greatly uneven (the joints between the single outer layers 26a to 26c are slightly discontinuous).
As shown in FIGS. 1 and 2, the shade body 3 on which the second skin layer 25 is formed in this way is erected on the top plate portion 9 of the body 2 by a small cylindrical portion 22. In the standing state, as shown in FIG. 2, the burning part 16 a of the wick 16 is disposed at a central position surrounded by the small cylindrical part 22.

Next, the usage method of the glass lamp 1 comprised in this way is demonstrated. First, lamp oil as fuel is supplied into the accommodating portion 7 through a through hole 10 formed in the top plate portion 9 with the wick cap 15 removed from the body 2. Then, the lamp core cap 15 is reattached to the cap support 11 while the lamp core 16 is immersed in the lamp oil. Next, the combustion part 16a is ignited, and the cap body 3 is erected on the top plate part 9 of the body 2 while being covered with the flame rising from the combustion part 16a. Then, the flame is arranged in the vicinity of the vertical center of the shade body 3 and illuminates the surroundings through the glass from the inside. The hot air of the flame is radiated from the opening 19.
More specifically, since the light illuminates the outer skin layer 25 through the inclined wall portion 17, the surroundings are illuminated with various lights transmitted through the outer skin layer 25, and the inclined wall portion 17 itself also transmits the outer skin layer 25. The light is illuminated with a color corresponding to each color tone of the first to fourth single outer layers 26a to 26d. At this time, since the transmissivity varies depending on the thickness of the recess 33, the outer skin layer 25 (the first to fourth single outer layers 26a to 26d) is illuminated with different brightness even if the light source is the same. It becomes.
Further, since the second bottom plate portion 18 is not formed with the outer skin layer 25 and remains a transparent glass substrate, the light transmittance in this direction is higher than that of the inclined wall portion 17 where the outer skin layer 25 is formed. It has become. Moreover, since the top plate part 9 of the body 2 is not formed with the outer skin layer 13 and remains a transparent glass substrate, the transmissivity is high. Therefore, the light reaching the top plate portion 9 from the second bottom plate portion 18 does not decrease so much, reaches the inside of the body 2 and illuminates the first outer skin layer 13 through the peripheral wall 6.
Further, since the gold foil 31 is disposed between the fourth single outer layer 26d near the outer periphery of the inclined wall portion 17 and the inclined wall portion 17, the golden light reflected by the gold foil 31 is reflected on the second bottom plate. The area below the shade body 3 is illuminated through the portion 18. The gold foil 31 is visually observed through the outer skin layer 25 (fourth single outer layer 26d) of the inclined wall portion 17.

By configuring as described above, the following effects can be achieved in the present embodiment.
(1) Compared to the conventional glass lamp welding work in glass lamps, it does not require heating, so the production skill is not required. The outer skin layers 13 and 25 can be formed. As a result, it is possible to obtain a glass lamp with a more precise design. Further, since the coating material for the outer skin as the material constituting the outer skin layers 13 and 25 is not heated, a material (not limited to a colorant) that can be modified by conventional heating can be used, and the range of design is widened. .
(2) Since the light source is disposed on the shade body 3 side, it is difficult for light to reach the body 2 side.
Since the second bottom plate portion 18 and the top plate portion 9 are transparent, the light can reach the inside of the body 2 sufficiently to illuminate the first outer skin layer 13 through the peripheral wall 6.
(3) When the outer skin layer 25 is illuminated through the inclined wall portion 17 of the shade body 3, the inclined wall portion 17 has formed several concave portions 33a to 33c having different depths, so that the light transmittance can be changed. In combination with the first to third single outer layers 26a to 26c formed in the recesses 33a to 33c, various transmittances can be set, and the width of the design is widened.
(4) Since the outer periphery of the glass substrate is covered with the outer skin layers 13 and 25, the outer skin layers 13 and 25 become a kind of armor and the strength of the product is improved.

Note that the present invention can be modified and embodied as follows.
In the above embodiment, the concave portion 33 is formed as the background region. However, the flower pattern 27 is not necessarily formed as the background region, but the flower pattern 27 is formed of the flower core, the petal, the coral leaf, and the coral leaf. It is also possible to carve it into a sketch area.
-Although the glass lamp was mentioned as an example of the glass craft in the above, you may make it apply to other glass crafts (for example, an ornament, a vase, a stained glass, etc.).
-The shape and inclination angle of the inclined wall portion 17 of the shade body 3 can be changed as appropriate.
A single outer layer 14 may be used alone or in combination with a colorant other than rock paint (pigment). In particular, in the present invention, since it is not exposed to high heat as in the prior art, it is possible to use a colorant that is relatively weak against heat.
-The glass substrate does not need to be colorless and transparent, and may be a colored transparent body.
-The light source of the lamp may be a light bulb.
-In addition, it is free to implement in a mode that does not depart from the spirit of the present invention.
