Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glass plate that can be used for automobile windows, building windows, etc., and that can be seen through from certain directions but not from other directions.

Conventionally, the rear window of a car, for example, was usually made of a completely transparent glass plate, and in order to prevent sunlight from directly entering the interior of the car, the window glass itself was made to have a smoked look, or The problem was dealt with by installing separate curtains, etc. inside the car. However, by making the window glass itself smoke-like, or by installing a separate curtain or the like, although the amount of sunlight entering the vehicle is reduced, it also has the disadvantage that it becomes somewhat difficult to see outside the vehicle from inside the vehicle.

In view of the above points, this invention makes it easy to see from the inside of the car to the outside of the car, and makes it difficult for light to enter the inside of the car from outside the car.In other words, the line of sight from inside the car, for example, the line of sight from the side, can be transmitted to the outside of the car. Light rays or line of sight from outside the vehicle (from above)
Our objective is to provide a glass plate that can be seen through from a predetermined direction but not from other directions.

The gist of this invention is a glass plate formed by joining two plates made of transparent materials, in which a concavo-convex surface that fits into each other is continuously formed on the joining surface of each plate, and the concave-convex surface There is provided a glass plate characterized in that a shielding layer that cannot be seen through is formed on a predetermined surface so that it can be seen through only from a predetermined direction.

Hereinafter, embodiments of the present invention will be described based on illustrated examples.

Fig. 1 is an exploded view of a glass plate showing a first embodiment of the present invention, Fig. 2 is a plan view of a glass plate of the same embodiment, and Fig. 3 is a second embodiment of the glass plate.
FIG. 4 is an exploded view of the glass plate of the embodiment, and FIG. 4 is a plan view of the glass plate of the embodiment.

The glass plate 1 of the first embodiment is formed by joining two plates 2 and 4 made of a synthetic resin material such as transparent acrylic polycarbonate or a transparent material such as inorganic glass.

A sawtooth-like uneven surface 3.5 consisting of inclined surfaces 3a, 5a and vertical surfaces 3b, 5b is continuously formed on the joint surfaces of the plates 2 and 4, respectively, and these uneven surfaces 3.5 .4 are formed to fit together when joined.

Further, on the inclined surface 3a of each uneven surface 3 of the plate material 2, a shielding layer 6, which cannot be seen through, is formed by a coating film, metal foil, or the like.

The glass plate 1 is formed by joining the plate materials 2 and 3 with a transparent adhesive or by clamping the edges thereof.

Therefore, this glass plate l, as shown in FIG.
It is completely transparent except for the thickness of the shielding layer 6 from the A direction, which is the inclination direction of the slope 3a on which the shielding layer 6 is formed, and it is shielded by the shielding N6 and is transparent from other directions such as B direction and C direction. It becomes impossible.

The glass plate 11 of the second embodiment is formed by joining two plates 12 and 14 made of the same transparent material as in the first embodiment. A horizontal surface 13a having a horizontal surface 13a.

15a and the vertical surface 13b, and 15b and the uneven surface 13.15 in the shape of a collar are formed continuously, and these uneven surfaces 13.15 are formed so as to fit together when the plate material 12.14 is joined. ing. And each uneven surface 13
．． 15, the protruding horizontal surfaces 13a, 15a
A non-see-through shielding layer 16 such as a paint film or metal foil is formed on the glass plate 1, and the plate materials 12 and 14 are joined together using a transparent adhesive or a clamping means at the periphery, similar to the glass plate 1 of the first embodiment. A glass plate 11 is formed.

Therefore, as shown in FIG. 4, this glass plate 11 is blocked by the shielding layer 16 from the direction perpendicular to the surface on which the shielding layer 16 is formed, and cannot be seen through it, and from the direction A,
It is possible to see through the gap in the shielding layer 16 from the direction C.

In addition, the uneven surface of each plate material that makes up the glass plate is
In addition to those shown in the first and second embodiments, various shapes such as a mountain shape such as an equilateral triangle, a wave shape such as a sine curve, and those in which these shapes are continuous in size can be applied when mated, and it can also be applied to uneven surfaces. The shielding layer to be formed may be formed entirely or partially on a desired predetermined surface of the uneven surface, taking into consideration the transparent direction and non-transparent direction.

As described above, the glass plate according to the present invention is formed by joining two plates made of a transparent material, and the joined surface of each plate has a continuous uneven surface that fits together,
A shielding layer that cannot be seen through is formed on a predetermined surface of the uneven surface, and can be seen through from a certain direction but not from other directions. It is strong because it is bonded to the glass plate, and if the shielding layer is colored, it has a decorative effect. Even if the shielding layer is colored, the color tone changes because the shielding layer is formed inside the glass plate. It can be used for the windows of buildings and doors of furniture, etc. For example, when used for the rear window of a car, it can block sunlight and prevent the temperature inside the car from rising.
