Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multilayer windowpane structure in which light shielding (shielding) and lighting can be varied, and a method of manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, as a double-glazing structure capable of shading and daylighting, a double-glazing structure with a built-in blind having both functions of a double-glazing structure and a blind has been used (for example, see, for example, Japanese Patent Laid-Open Publication No. H11-163873). JP-A-3-69788). Although the double-glazed window glass structure with a built-in blind has a problem that the configuration is relatively complicated and expensive, it has a high value as a building glass sheet because it has both functions of the window glass and the blind.

[0003]

However, the conventional double glazing structure 51 with a built-in blind, shown in a cross-sectional view in FIG. 12, incorporates an existing single blind 52 into the space layer 53 of the double glazing. Although it is disposed, the blade width of the existing blind 52 is usually about 15 mm, and the space between the inner walls of the two sheet glasses 54 forming the space layer 53 is 5 mm.
5 is at least 2 including a gap corresponding to the play of the blind 52.
0 mm is required. In this case, when a plate glass having a thickness of 3 mm is used, the total thickness is 26 mm in a double-layered window glass having two layers.
Becomes In FIG. 12, reference numeral 43 denotes a spacer at the periphery of the multilayer window glass structure 51.

However, the internal dimensions of the glass fitting portion of existing sashes for double glazings are 20 to 28 mm, and there are some sashes to which the multi glazing structure 51 can be attached. The double glazing structure 51 cannot be used in a sash for glazing. In addition, in terms of earthquake resistance, the gap between the glass fitting portion of the glass sash and the glass plate must be at least 2 mm on one side. Considering this restriction, the total thickness of the double-glazed window glass structure must be 16 to 24 mm. No.

Further, when the multi-layer window glass structure 51 is used as a fire-resistant structure, at least one side of the glass plate 54 must be a meshed glass plate. When the total thickness is 16 mm and the total thickness is 16 mm, the thickness of the meshed glass sheet is 6.8 mm, and when the thickness of the other glass sheets is 3 mm, the inner walls of the two glass sheets forming the space layer are formed. The space 55 between them is about 6 mm, and there is no space for the blind 52 to enter. Even if you put blinds,
A blade with a blade width of 5 mm or less must be made, which is not realistic. Therefore, the above-mentioned multilayer window glass structure 51
Is not applicable to existing glazing sashes.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks of the prior art, and it is possible to use conventional blinds even in a double glazing structure in which a space between two or more glass sheets forming a space layer is narrow. An object of the present invention is to provide a multi-layered window glass structure having a function of changing a light shielding function and a lighting function without performing the same.

[0007]

According to the present invention, a space layer is formed between a plurality of glass sheets and a frame disposed around the periphery of the glass sheet, and the space layer has a light shielding member. A multilayer windowpane structure, wherein the light-shielding member is a foldable pleated member, and the multilayer is stretched between a fixed frame and a movable frame disposed in the space layer. Provide glazing structure.

[0008] By adopting such a structure, the same function as that of the conventional double-pane glazing structure using a blind can be obtained and the total thickness can be reduced. It can be mounted in the glass fitting part with a sufficient margin, and both the problem of construction and the problem of earthquake resistance can be solved.

[0009]

In the present invention, when the movable frame moves vertically or horizontally with respect to the fixed frame, the pleated member of the light shielding member expands and contracts, and the light shielding function and the lighting function can be changed. It is preferably a structure. Instead of using a method of suspending the blades of the blind as in the conventional blind, the light shielding member is a pleated member that can be bent, and the light shielding member is stretched between the fixed frame and the movable frame. The light-shielding function and the lighting function can be changed not only by moving vertically but also horizontally.

[0010] In the present invention, the fixed frame and the moving frame may be plural at a predetermined interval.
It is preferable that the frames are arranged in the order of the fixed frame and the moving frame, or in the order of the moving frame and the fixed frame.

Further, a pair of fixed frame and moving frame are
For a pair of fixed frame and moving frame adjacent vertically or horizontally,
When each pair extends, the fixed frame of one pair and the moving frame of the other pair should be positioned without any gaps in the vertical or horizontal direction, so that light shielding and lighting should be performed over the entire surface of the multilayer window glass. It is preferable because it can be performed effectively. As described above, by providing a plurality of fixed frames and moving frames in pairs, the light shielding function and the lighting function can be changed even if the moving distance of the moving frame is small.

Further, in the present invention, the fixed frame and the moving frame are long members having a substantially U-shaped cross section, and the light shielding member is housed inside the fixed frame and the moving frame during lighting. Preferably, there is.

That is, the substantially U-shaped cross sections of the fixed frame and the moving frame are such that when the substantially U-shaped long members face each other, the two substantially U-shaped openings face each other. In addition, when the fixed frame and the moving frame are in contact with each other, it is preferable that the cross section between the substantially U-shaped openings is substantially a rectangular space. With such a configuration, at the time of daylighting, that is, in a state where the fixed frame and the moving frame are in contact with each other, the light shielding member is housed inside the fixed frame and the moving frame, and the fixed frame and the moving frame appear as an integral frame. It is preferable both in terms of design and design.

In manufacturing the double glazing structure of the present invention, after the light-shielding mechanism mainly including the light-shielding member, the fixed frame and the movable frame is assembled, the light-shielding mechanism is interposed between a plurality of sheet glasses. Is preferably provided. As described above, by adopting a method in which the light shielding mechanism is assembled between a plurality of glass sheets after being assembled in advance,
The work process can be simplified.

When a resin material such as polyvinyl chloride or polycarbonate is used for the light-shielding member 15, the cross-sectional shape of the bent portion of the pleat is set so as to withstand repetition in order to increase the repetition durability of the pleat portion. It is also conceivable to devise a device. For example, as shown in FIG. 11, if the bent portion is not formed into a mere square shape but is formed into a shape in which an arc-shaped convex portion is formed, durability against repeated bending can be improved. In FIG. 11, (a) shows a state in which the pleats are extended (that is, a state in which light is blocked).
