2. Description of the Related Art Japanese Patent Laid-Open Publication No. Hei.
As described in JP-A-253499, a glass cullet powder is adhered to a surface of a large-grain glass cullet with an organic adhesive and placed on a glass or ceramic surface, and the glass powder is melted, but the large glass cullet is melted It has been proposed to fix a large glass cullet to the surface of glass or ceramic by heating under a temperature condition that does not deform.

However, in the method of heating and melting the glass cullet powder in a furnace and fixing the large glass cullet to the surface of glass or ceramics, the glass cullets are adhered to each other using a mold or the like. It is not possible to compose a product by itself.

SUMMARY OF THE INVENTION
No. 43922 describes that a light diffuser of a lighting fixture is formed using a transparent piece of glass.

However, if a heating element such as a lamp is disposed inside, there is a danger that the heat will be trapped and overheated. Further, when a candle or the like is disposed inside, there is a possibility that oxygen will be depleted and incomplete combustion will occur. In addition, it is impossible to create a romantic atmosphere by burning candles.

When a lamp shade or the like is composed only of glass cullet, there is no support, and there is a possibility that the lamp shade will be broken or broken.

The technical problem of the present invention is to solve the problems of air permeability and insufficient strength when a glass cullet is bonded to realize a lamp shade or the like, paying attention to such problems.

[0008]

The technical problem of the present invention is solved by the following means. A first aspect of the present invention is a glass cullet product in which a lamp shade or the like is formed by joining glass cullets with an adhesive, and a gap is formed between the glass cullets to allow communication between the inside and the outside of the lamp shade or the like.

As described above, the glass cullets are joined to each other with an adhesive to form a lampshade and the like, and a gap is formed between each glass cullet such that the inside and outside of the lampshade and the like communicate with each other. Ascending airflow is generated by heat generated from a light bulb or the like, and fresh air flows from the outside to the inside through the gap between the glass cullets.

Therefore, it is possible to prevent the temperature inside the lamp shade or the like from rising abnormally. When a candle is used, incomplete combustion due to lack of oxygen can be prevented. In addition, when a windmill or a turning lantern is rotated using the flow of airflow, the shadow is reflected on a lampshade or the like, so that it looks more beautiful and shining.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the glass cullet product and the method for producing the same according to the present invention will be described. FIG. 1 is a view showing an embodiment of a glass cullet product, and is a cross-sectional view applied to a lamp shade. FIG. 2 is an enlarged sectional view of a portion A in FIG. The lamp shade 6 has a substantially cylindrical side wall 8 so that the lamp 7 enters therein, and is connected to a base 9.

Although both the side wall 8 and the base 9 are formed by bonding only glass cullet, a gap G is formed between the adjacent glass cullets C as shown in FIG. It is formed so that it can be done. This can be easily realized by using an adhesive having a relatively high viscosity and making the amount of the adhesive smaller than that of the glass cullet.

In the figure, the gap G is not continuous between the outside and the inside of the side wall 8, but there is also a gap in the direction perpendicular to the paper surface. Air can flow between the inside and the inside.

Therefore, when an upward airflow is generated by the heat generated by the internal lamp 7, air flows in from the outside through the gap G of the side wall 8 as indicated by an arrow, so that the inside of the lamp shade does not overheat. Also, put a candle inside,
When the glass cullet lid is placed on the upper side, fresh air is supplied from the side wall, so that the candle does not disappear due to lack of oxygen.

As shown in FIG. 1, when a windmill with blades 10 is mounted on a lamp 7 and is supported rotatably, the windmill rotates between the blades 10 due to the airflow rising. Then, the shadow appears on the side wall 8. Or feather 1
If a lantern is integrated with the lantern, the rotating lantern can be seen in rotation. In this way, the rotating body inside the lamp shade can be rotated by the airflow, so that a fantastic unique atmosphere can be created.

By arranging glass cullets of different colors and sizes depending on the location of the lamp shade, a desired pattern such as a landscape or a pattern can be expressed. In addition, as long as a gap that communicates the inside and outside is required, the present invention can be applied to other than the lamp shade.

The lamp shade can be easily molded by using a mold. FIG. 3 is a view showing an embodiment of a mold for molding. The inner frame 11 is shown in a side view, and the outer frame 12 is shown in a sectional view. The inner frame 11 is hollow to reduce the weight.

As described above, with the inner frame 11 inserted into the outer frame 12 in the shape of a lamp shade, the two frames 11, 12
The gap 13 between them is filled with a glass cullet covered with an adhesive. At this time, a glass cullet having a different color or size is filled depending on the location according to a pattern such as a pattern or a figure to be expressed.

After the filling is completed, the adhesive is hardened by leaving it for a predetermined time, and then the inner frame 11 and the outer frame 12 are removed and the mold is released. It should be noted that both frames 11 and
It is effective to apply salad oil or the like in advance on the surface that comes into contact with the glass cullet No. 12. The release agent is
Not limited to salad oil.

When the adhesive is applied to the inner and outer surfaces of the side wall 8 after the mold release, the mechanical strength of the lamp shade can be increased, and the adhesive is not attached because it is in contact with the molds 11 and 12. The surface can also be reliably covered with the adhesive, and polishing can be performed.

The use of the technique shown in FIG. 3 is effective not only in the manufacture of lampshades, but also in the manufacture of ornamental flowerpots and accessories for orchid cultivation.

FIG. 3 shows an example in which both inner and outer molds are used. However, depending on the shape of a product, only the outer frame 12 or only the inner frame 11 can be used. For example, when only the inner frame 11 is used, a glass cullet coated with an adhesive is adhered to the outer surface of the inner frame 11. When only the outer frame 12 is used, glass cullet is adhered to the inner surface of the outer frame.

As described above, when only one mold is used, the color and size differ depending on the location, as compared with the method of filling the gap between the pair of molds with glass cullet as shown in FIG. The work of arranging the glass cullet is simple, and the pattern formation is easy.

When it is not necessary to form a gap between each glass cullet, a product can be made with the glass cullet attached to the mold. In this case, it goes without saying that the release agent is not applied.

As the adhesive used in the present invention, a urethane-based or other known synthetic resin adhesive can be selectively used. A type using a curing agent together may be used.

The size of the glass cullet used is 5 m
m to a powdery substance, but depending on the location, it is more effective to use a large substance of about 5 mm to 5 cm in combination.

[0029]

According to the first aspect of the present invention, a lamp shade or the like is formed by joining glass cullets with an adhesive, and a gap is formed between each glass cullet to allow communication between the inside and the outside of the lamp shade or the like. As a result, ascending airflow is generated by heat generated from an internal light bulb or the like, and fresh air flows from the outside to the inside through the gap between the glass cullets.

Therefore, it is possible to prevent the internal temperature of the lamp shade or the like from rising abnormally. If the windmill or the turning lantern is rotated by utilizing the flow of the air current, the shadow is reflected on the lamp shade or the like. It looks beautiful and shines. Even if a candle is used, there is no danger of incomplete combustion due to lack of oxygen.
