JPH0573194U - Window glass that can prevent each other from stealing - Google Patents

Abstract

(57) [Abstract] [Purpose] To provide a window glass which is transparent window glass for a high-rise building or the like and which can prevent each other from being stolen inside by another building adjacent thereto. [Structure] A window glass of a building or the like, in which a polarizing film having different polarization angles of 90 degrees from each other is attached to the surface of a transparent window glass facing each other at an arbitrary angle, and one window glass is passed through the other. Looking at the window glass, due to the action of the polarizing film, it appeared black, and the inside of the window glass was not visible.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a windowpane capable of preventing the insides from being stolen through the windowpanes of other buildings adjacent to each other in a high-rise building or the like.

[0002]

[Prior Art]

 The window glass of high-rise buildings and the like is transparent, but this may cause the inside to be stolen from the outside. In order to prevent this, conventionally, a mirror-finished film is attached to the window glass so that the inside cannot be seen from outside. According to this method, it is effective to prevent thieves in the daytime, but it is impossible to prevent indoor thieves from the outside at night because the room can be seen from the outside by using lighting in the room at night.

[0003]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide a transparent window glass for a high-rise building and the like, which can prevent the insides of other adjacent buildings from being stolen through the window glass. Is.

[0004]

[Means for Solving the Problems]

 The present invention has been made for the purpose of solving the above problems, and its structure is a windowpane of a building or the like, and a transparent windowpane facing each other at an arbitrary angle has polarization angles of 90 degrees each. It is characterized in that it is formed by attaching different polarizing films.

[0005]

【Example】

 Next, an example of implementation of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a building to which the window glass of the present invention is attached, and FIGS. 2 and 3 are sectional views of the respective window glasses.

In the figure, 1 is a window glass of a building A, 2 is a window glass of a building B, and the buildings A and B are built with a certain angle, and the surfaces of the window glasses 1 and 2 are 90 degrees apart from each other. The transparent polarizing films 1a and 2a having different polarization angles are adhered to each other, and the above constitutes the window glass of the present invention.

In the window glass of the present invention configured as described above, when the window glass 2 of the building B is seen from the inside of the building A through the window glass 1, the window glass 2 is formed by the polarizing action of the polarizing films 1a and 2a. Looks black, and when the window glass 1 is viewed from the inside of the building B through the window glass 2, it looks like black as well, so that the insides of the window glasses 2 and 1 cannot be seen from each other. Therefore, if these window glasses 1 and 2 are used for the window glass of a high-rise building where the windows cannot be opened and closed, the privacy through the window glass can be protected. Moreover, when the conventional window glass with a mirror-finished film is used for indoor lighting at night, the inside of the window glass can be stolen from the outside, but the window glass of the present invention does not have such a threat. .

[0008]

[Effect of the device]

 The present invention is as described above, and since it is not possible to see the inside of the window glass from each other day and night, it is possible to protect the privacy through the window glass, and thus the opening and closing of the window is prevented. It is extremely useful as a window glass for high-rise buildings that cannot.
