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 ensuring only translucency from a predetermined angle direction.

[Prior Art] Conventionally, as a method for blocking the line of sight from the outside in a window glass, a shielding material such as a curtain or a blind is externally attached to the window glass, and this is opened and closed to shield the window. Many of them have variable structures.

Further, when the window glass has a double-layer structure like a double window, a shielding means such as a blind or a film-like shielding material is built in the internal space formed between the glass plates. There is also a structure in which an external operating means is driven and operated according to the intended purpose and the degree of shielding is variable.

[Problems to be Solved by the Invention] However, there is a problem that the effective space in the room is reduced by that much when the window glass is attached with a shielding material such as a curtain externally.

Further, in the case of the type in which the shielding means is built in the inner space of the double glazing, it is necessary to store the drive mechanism which requires a relatively large space in the same inner space. Not only was the overall thickness increased, but there was a possibility that the mechanism would become complicated and there would be many failures. Further, since the drive mechanism for the shielding means built in the double glazing requires an appropriate operating mechanism such as a handle for operating from the outside, it is necessary to provide an appropriate operating mechanism between the operating mechanism and the drive mechanism. Also required the interposition of mechanical coupling means. Since the presence of this connecting means causes the result that the airtightness of the double glazing is lowered, it not only allows the entry of dust and the like into the internal space, but also lowers the heat insulation due to the lack of airtightness. There was also the problem of deriving.

[Means for Solving Problems] The present invention has been made in view of the above problems of the prior art, and its structural feature is that a plurality of glass plates are formed through a spacer arranged at the peripheral portion. In a laminated double-glazing unit, a transparent sheet member having a shape-retaining property is used as a base material in the internal space formed between the glass plates, and the light-shielding surface and the non-light-shielding surface are alternately zigzag-shaped. The bent member formed so as to be positioned in the form of a sheet is stretched so as to come into contact with the glass plate at the bent edge, and the bent edge group on one side and the bent edge group on the other side are The space a between the glass plates is equal to or more than the space b between the glass plates defined by the width of the spacer before being stretched in the internal space, and the space a and the space b have the same length and are bent. The member is fixedly stretched in the internal space.

[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 concrete structure of a double glazing as an embodiment of the present invention. Two transparent glass plates 1 and 2 are made of a hard rigid member such as metal. By arranging the spacers 4 and 5 to be formed in the peripheral portion located on the four circumferences thereof, the internal space 7 as shown in FIG. 2 is formed and bonded and fixed in an airtight manner. Although the multi-layer glass in the present invention is shown to be composed of two glass plates according to the illustrated example, it is of an appropriate structure using three or more glass plates. Good.

In this way, in the internal space 7 formed between the glass plates 1 and 2, the light-shielding surface 12 and the non-light-shielding surface 13 are alternately arranged in a zigzag shape. 11 is stretched so as to cover the entire glass surface.

That is, the folding member 11 uses a transparent sheet member such as plastic having a shape-retaining property as a base material, and the light-shielding surface 12 and the non-light-shielding surface 13 are alternately positioned with a constant width with respect to the transparent sheet member. And each of them has the same interior angle θ and is bent in a zigzag shape by repeating mountain folds and valley folds.

Further, as shown in FIG. 1, in the bending member 11, the distance a between the group of bent edges 14 on one side and the group of bent edges 15 on the other side before being stretched in the internal space 7 is , The glass plates 1 and 2 defined by the width of the spacers 5 are formed so as to hold a distance b or more between the glass plates 1 and 2, and the bending member 11 formed in this way has the second distance a. As shown in the figure, it shifts to a space a'having a length equal to the space b and is fixedly stretched in the internal space 7.

In this case, the internal angle θ of the bending member 11 in which the mountain folds and the valley folds are repeated can be appropriately set to a desired translucency or light blocking property of the bending member 11 by selecting an arbitrary angle. You can

The light-shielding surface 12 of the bending member 11 can be appropriately formed by applying an appropriate color having a light-shielding property or by attaching a light-shielding tape. Further, the non-light-shielding surface 13 of the bending member 11 may be formed in a transparent state, or may be formed in a light-transmissive state without transparency.

FIG. 3 shows the light-shielding surface 12 and the non-light-shielding surface of the bending member 11.
It is another example of a bending situation with the non-light-shielding surface 13, and the non-light-shielding surface 13 is positioned so as to be substantially horizontal and arranged at equal intervals, and these non-light-shielding surfaces 13 are arranged in an oblique direction. It is also possible to make a structure in which the light-shielding property is more emphasized by connecting at 12 and making the whole into a Z shape and continuing in zigzag.

Further, it is preferable that the bending member 11 is arranged in a state that it is hung in a comb shape like the illustrated example, but if necessary, although not shown, it is arranged in an accordion shape in the left-right direction. It may be. Furthermore, regarding the arrangement of the light-shielding surface 12 and the non-light-shielding surface 13 in the bending member 11, the light-shielding surface 12 in FIG. 2 is formed as the non-light-shielding surface 13 and the non-light-shielding surface 13 is formed as the light-shielding surface 12. You can also

Since the present invention is configured in this way, the glass plate
The bending member 11 before being stretched and arranged in the internal space 7 formed between the 1 and 2 includes a bending edge group 14 located on one side and a bending edge group 15 located on the other side. It is possible to keep the distance a between them equal to or more than the distance b between the glass plates 1 and 2 defined by the width of the spacer 5.

Moreover, the bending member 11 stretched in the internal space 7 shows a space a between the group of bent edges 14 located on one side and the group of bent edges 15 located on the other side in FIG. As described above, since it is possible to shift to the interval a ′ which is equivalent to the interval b of the internal space 7, the bent edges 14 contacting the inner surface of the glass plate 1 and the inner surface of the glass plate 2 are contacted at that time. contact friction force between the bent edge 15 a group of contacts, and, disposed because of its own shape retention, whatever without requiring a fixing member, under a state of being fixed to the initial positioning exactly, long-term You can leave it.

Furthermore, since the bending member 11 is composed of the light-shielding surface 12 and the non-light-shielding surface 13 that are continuously bent with a predetermined internal angle θ, only from the non-light-shielding surface 13 in a specific angle direction. It is possible to ensure the light-transmitting property or the light-transmitting property, and also the light-shielding property from other angle directions, and it can be effectively used from the viewpoint of privacy protection.

On the other hand, the bending member 11 built in the internal space 7 formed between the glass plates 1 and 2 can be arranged without being installed side by side with any driving mechanism or external operating means.
Since the space b of the internal space 7 can be formed narrower by that amount, and the external shielding material such as curtains and blinds can also be wiped out, it is possible to secure a wider effective space in the room. . Further, since the structure that is excellent in airtightness can be obtained by eliminating the connecting means that is necessary when the drive mechanism and the external operating means are provided, it is possible to prevent dust from entering the internal space 7. Not only can it be suppressed, but it can also be made more excellent in heat insulation.

[Effect of the Invention] As described above, according to the present invention, the bending member has the space between the bending edge group on one side and the bending edge group on the other side before being stretched in the internal space. a is maintained between the glass plates at a distance b or more, and after being stretched, the glass plates are moved so as to be equal to the space b and fixedly stretched in the internal space to form between the glass plates. Since the bending member having the light-shielding surface and the non-light-shielding surface can be arranged without requiring any fixing member in the internal space, the light-shielding property can be obtained only from the predetermined angle direction without using the drive mechanism. It is possible to protect the privacy by securing it, and since the airtightness of the internal space can be made higher by not requiring a drive mechanism, it is possible to effectively prevent the intrusion of dust and the like. Not only can we provide double glazing with excellent heat insulation. Wear.
