DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated glass for an entrance door mounted on an entrance door of a house or the like.

[0002]

2. Description of the Related Art Generally, glass is assembled on a front door of a house from the viewpoint of improving design, and this glass is required to have functions such as durability, crime prevention, and ultraviolet rays. Therefore, laminated glass is often used. Conventionally, as the laminated glass for the entrance door, for example, those having a structure shown in FIGS. 6 to 8 are known.

[0003] First, a laminated glass 100 for an entrance door shown in Fig. 6 is a laminated surface 101a of a pair of glass 101, 102 made of transparent (or translucent) plate glass, foam glass, crack glass, milk glass, or the like. 102
For example, a transparent or colored PVB film 103 or the like is interposed between “a” and both glasses 101 and 102 are heat-welded using the adhesiveness of the PVB film 103.

A laminated glass 100 for an entrance door shown in FIG. 7 is a laminated surface 1 of a pair of glasses 101 and 102.
A patterned film 104 on which a stripe 104a is printed is interposed between the first and second glass substrates 101a and 102a, and both glasses 101 and 102 are heated by utilizing the adhesiveness of the patterned film 104, similarly to the laminated glass 100 shown in FIG. It is welded. Further, a laminated glass 100 for an entrance door shown in FIG.
A PET film 105 and a pair of EV films 106 are interposed between 1a and 102a, and the two glasses 101 and 102 and the PET film 105 are thermally welded by, for example, vacuum evacuation heating using the adhesiveness of the EV film 106. It was made.

[0005]

However, in the laminated glass 100 for the entrance door, the films 103 to 103 interposed between the pair of glasses 101 and 102 are used.
From the productivity of 106, since its thickness is limited to a maximum of about 400 μm, it is thin and easy to be planar, and it is difficult to impart a pattern or the like to the films 103 to 106, The laminated glass 100 itself does not have a sense of depth (three-dimensional appearance), and it is difficult to enhance the design value of the entrance door.

Therefore, in order to enhance the design value of the entrance door, the above-mentioned foam glass, crack glass, or the like is used as the pair of glasses 101 and 102, or the surface of the laminated glass 100 is decorated with a gold molding, Although secondary processing such as sticking a film on is performed,
In these cases, there is a problem in that the glasses 101 and 102 themselves become expensive or work costs increase, and as a result, the cost of the entrance door tends to increase.

Further, between a pair of glasses 101 and 102,
Since only the heat-resistant films 103 to 106 etc. are interposed, the laminated glass 100 itself has poor fire resistance and impact resistance, and it is difficult to obtain sufficient fire resistance for the entrance door, For example, when the glass is broken by an impact, it is difficult to prevent the broken glass from scattering. Therefore, for example, in order to prevent scattering of the glass 101, 102,
The use of netted glass or the like is also used, but also in this case, the glass itself becomes expensive, and there is a problem that the cost of the entrance door is easily increased.

The present invention has been made in view of such circumstances, and an object of the present invention is to bond and bond a pair of glasses via an interlayer provided with a design and having a glass scattering preventing function. It is an object of the present invention to provide a laminated glass for an entrance door, which can improve design value and ensure sufficient strength at a low cost. Another object of the present invention is to provide a laminated glass for a front door, which facilitates the formation of a design on an interlayer film and can form the laminated glass at a lower cost, and can further improve the design value. .

[0009]

In order to achieve the above object, the invention according to claim 1 of the present invention has a predetermined design between the mating surfaces of a pair of glass and prevents scattering of at least broken glass. It is characterized in that both glasses are joined and bonded with an intermediate film having a function interposed therebetween.

[0010] With this configuration, when an interlayer provided with a design is interposed between the pair of glass mating surfaces and bonded and bonded, a sense of depth is given to the laminated glass itself by the design of the intermediate film. It is easily obtained and enhances the design value of laminated glass for entrance doors. In addition, since the interlayer has at least a glass scattering prevention function, the scattering of broken glass is reliably prevented without using netted glass or the like, and the laminated glass has sufficient strength and safety simultaneously and inexpensively. Can be secured.

In the intermediate film, the design is formed by kneading a design forming material at the time of manufacture, as in the invention according to claim 2, or the intermediate film has a different design as in the invention according to claim 3. A design is formed by patterning a plurality of intermediate film pieces, or a design is formed by a printed pattern printed on the surface or a design forming material pressed into the surface as in the invention according to claim 4. Is preferred.

[0012] With this configuration, for example, a design forming material such as fibers or particles is kneaded during the production of the intermediate film, a plurality of intermediate film pieces having different designs are applied in a pattern, or printed on the surface, or Since the design is formed on the interlayer film by pressing the forming material, the design itself can be formed easily and inexpensively, and the design value of the laminated glass is further improved depending on the setting of the design forming material and the pattern pasting. .

The invention according to claim 5 is characterized in that a glass or a film having a design effect is interposed between the mating surfaces of a pair of glasses. The design effect of the glass or film is synergistic with the design effect obtained by the design to have, and the design value of the laminated glass is further improved.
