Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a double glazing, and more particularly to a double glazing capable of continuously changing the amount of transmitted light.

[Prior Art] By adjusting the amount of transmitted light, it is intended to shield the sunlight from the double glazing used as windows or to block the line of sight from the outside. It is already known that the inner space formed in the inside has a shielding means such as a blind or a curtain-shaped shielding material. Since the shielding means having such a structure is housed in the internal space formed in the double glazing, it is necessary to additionally provide a driving means for driving the shielding means according to the intended purpose. However, the amount of transmitted light can be adjusted by winding or opening and closing through this driving means.

[Problems to be Solved by the Invention] However, in the double glazing having the above-described structure of the shielding means built-in, the shielding means itself is complicated, and is composed of a winding mechanism and an opening / closing mechanism that take up space. Therefore, there is a problem in that an internal space commensurate with that must be secured, and as a result, the total thickness of the double glazing itself increases.

Further, the shielding means in the laminated glass needs to be operated from the outside by some means, and therefore, an operating mechanism such as a handle is arranged on the outside, and the operating mechanism and the shielding means are mechanically arranged. It had to be connected to each other via a connecting means. Therefore, the double glazing is difficult to completely seal the internal space because of the presence of the connecting means, as a result not only allow dust and the like to enter the internal space and stain it. There is also a problem that the heat insulation is deteriorated due to insufficient airtightness.

The present invention has been made in view of the above problems of the prior art, and its object is to maintain the airtightness of double glazing,
Moreover, it is to provide a double glazing having a necessary shielding function.

[Means for Solving Problems] The present invention has been made to achieve such an object, and is characterized in that a plurality of glass plates are sealed by spacers arranged on four circumferences. In the inner glass space formed between the glass plates, a circular transparent plate member having a polarizing film on one surface thereof and a guide plate having a circular hole into which the circular transparent plate member is fitted are A magnet that allows the rotation to be externally braked by a magnetic force or a member that is attracted by the magnet is fixed to the circular transparent plate member that is rotatably enclosed, and is attached to any one side surface of the glass plate. Is that the polarizing film is disposed so as to face the polarizing film surface of the circular transparent plate material.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing a constitutional example of a double glazing unit according to the present invention. One side of two glass plates 1 and 2,
For example, on the inner side surface of the glass plate 1 located on the left side, a circular hole having a polarizing film 5 on one side surface thereof and a circular transparent plate member 4 formed of a transparent acrylic plate or the like is rotatably fitted therein. A guide plate 8 formed of a transparent acrylic plate or the like in which the polarizing film 6 is disposed in a portion excluding the circular hole 9 and a circular hole having a diameter smaller than that of the circular transparent plate member 4. 12
By providing the above, the pressing plate 11 formed of a transparent acrylic plate or the like capable of supporting the circular transparent plate member 4 together with the glass plate 1 is integrally fixedly held. A friction coefficient can be applied to the circumferential end surface 17 of the guide plate 8 forming the circular hole 9 and the outer circumferential end surface 18 of the circular transparent plate member 4 rotatably fitted in the circular hole 9. In order to reduce the height of the circular transparent plate material 4, it is desirable to perform appropriate processing such as pasting a film material in advance so that the circular transparent plate material 4 can rotate smoothly.

On the other hand, on the other side of the two glass plates 1 and 2, for example, on the inner side surface of the glass plate 2 located on the right side, the polarization direction is different from that of the polarizing film 6 disposed on the guide plate 8. Mutually
The polarizing film 7 is arranged in such a positional relationship that it is displaced by 90 degrees.

The glass plates 1 and 2 having the above-described structure are provided with a spacer 3 made of a hard member such as a metal on the four circumferences thereof so that the inner spaces 16 are spaced at predetermined intervals as shown in FIG.
And is sealed.

In addition, the circular transparent plate material 4 after being stored in the internal space 16
Is formed rotatably along the inner peripheral end surface 17 of the circular hole 9 of the guide plate 8 by the rotational force urging means 13 including a pair of magnets 14 and 15. In particular, from the viewpoint of maintaining the airtightness of the internal space 16, the rotational force urging means 13
Is preferably formed by utilizing magnetic force. That is, by arranging a pair of magnets 14 and 15 formed in an appropriate shape and size so as to face the outer surface of one side of the glass plate 1 or 2 and the circular transparent plate member 4, the rotational force is applied. Means 13
And the magnet 14 positioned on the outer surface of the glass plate 1 or the glass plate 2 is artificially moved along the circumference of the circular hole 9 as shown in FIG. The circular transparent plate material 4 can be moved following the relationship with the magnet 15 on the side of, and as a result, it can be rotated.

The surface of the circular transparent plate member 4 on which the polarizing film 5 is arranged may be any one side surface. If the polarizing film 6 disposed on the guide plate 8 in FIG. 1 is in a positional relationship in which the polarization directions are deviated from each other by 90 degrees in relation to the polarizing film 7 on the glass plate 2 side. For example, in addition to the illustrated example, either one of the bonding surfaces of the glass plate 1 and the guide plate 8 may be used, and in some cases, the holding plate 11
It can also be arranged by being bonded to either one of the surfaces or the polarizing film 7 on the glass plate 2 side.

Regarding the rotational force urging means 13 for the circular transparent plate member 4, the magnet 14 is arranged only on the outer surface of either the glass plate 1 or the glass plate 2, and the circular transparent plate member 4 has
Instead of the magnet 15, a member such as an iron piece attracted by a magnetic force may be fixed, and the magnetic transparent force may force the circular transparent plate member 4 to rotate.

Furthermore, as for the double glazing to which the present invention is applied, it is possible to use a glass formed by using three or more glass plates.

Since the present invention is configured as described above, the circular transparent plate member 4 is freely rotated by the rotational force urging means 13 so that the circular transparent plate member 4 can be freely rotated in relation to the polarizing film 7 arranged on the glass plate 2. The polarization direction is parallel from 0 degree, which is orthogonal.
It can be changed steplessly up to 90 degrees, therefore
The amount of transmitted light can be freely adjusted.

Further, since the polarizing film 6 is arranged so that the polarization directions thereof are shifted from each other by 90 degrees in relation to the polarizing film 7 arranged on the glass plate 2, on the film surface where the both are overlapped,
It is possible to block the transmission of light, and in combination with the movement of the circular transparent plate member 4, it is possible to block the line of sight and the transmission of light over the entire glass surface, thereby ensuring privacy.

Further, the rotational force urging means 13 for the circular transparent plate member 4 is formed by using magnetic force, and the magnetic force is used to brake the circular transparent plate member 4 from the outside, so that the internal space formed between the glass plates 1 and 2 is formed. Not only can 16 itself be made relatively narrow, but its airtightness can be increased more than ever before, and it is possible to suppress the generation of dirt adhering to the inside, and further As a result, it is possible to suppress a decrease in heat insulation property, and as a result, it is possible to contribute to reduction of the heating and cooling load.

[Advantage of the Invention] As described above, according to the present invention, the air-tightness and the heat insulating property of the internal space formed between the glass plates are maintained to reduce the heating and cooling load, and also the circular transparent plate material. It is possible to adjust the amount of transmitted light according to the amount of insolation by rotating the steplessly, and it is also possible to secure privacy by effectively blocking the line of sight.
