Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved double glazed window.

Recently, the use of double-glazed glass for openings in structures such as houses and buildings has been widely talked about as an energy-saving measure.

As one type of double-glazed glass, flexible spacers, which are preformed into a ribbon shape with a roughly rectangular cross section from a sticky rubber-like substance containing a desiccant dispersed therein, are recently used along the periphery of a single glass plate. After laying the entire circumference, another glass plate is put together with this spacer in between, and these two glass plates are attached directly using the self-adhesive property of the spacer to create a hollow space at a predetermined distance. Double-glazed glass, as shown in Figure 1, is beginning to be used.

This type of double glazing has the advantage of being easy to assemble, as it is assembled by the method described above using self-adhesive and flexible spacers containing a desiccant, and is highly valued. .

On the other hand, the present applicant has previously proposed a fitting structure that simplifies the installation of double-glazed glass into the sash and window frame.
No. 06656 discloses a window glass fitting structure in which a window glass is fitted into a window frame body using a ribbed edge, the ribbed edge being in the shape of a cutout, and one side of which is fitted into the window frame body. , the other side is attached so that the window glass is sandwiched from the side to the window frame body, and both sides of the ridge are attached so that the window glass is fixed to the window frame body by the restoring force of the ridge. An application was filed regarding the inset structure.

By the way, the present inventor attempted to apply the above-mentioned type of double-glazed glass to the above-mentioned window glass fitting structure, but
Since it is attached by pressing the rim, the plastic spacer of the double-glazed glass is compressed or deformed, making it impossible to obtain double-glazed glass with a predetermined spacing. Also, the double-glazed glass deforms during use. Disadvantages were found, such as reduced adhesion between the spacer and the glass plate.

The present inventor has improved the above points, and provides a double-glazed window that improves the dew point maintenance performance without deforming the spacer of the double-glazed glass, and that is simplified in construction.
A multilayer structure in which multiple glass plates are bonded and spaced apart at predetermined intervals using spacers made of a flexible plastic material that is self-adhesive and contains a desiccant dispersed in the window frame body. In a double-glazed window in which glass is fitted using a rim, a portion of the spacer of the double-glazed glass has a width sufficient to prevent deformation due to compression of the spacer and maintain the distance between the glass plates of the double-glazed glass. and a rib having a cross-section with a cross section having a vertical side located on the peripheral side surface side of the double glazing glass and a horizontal side located on the end surface side of the double glazing glass. on the window frame body so as to fit into the protruding piece protruding from the end surface side of the double-glazed glass of the window frame body, and so that the vertical side is sandwiched from the side surface of the peripheral part of the double-glazed glass to the window frame body. The double-glazed window is characterized in that the ridge is fixed to the window frame body by a restoring force caused by the displacement of the longitudinal and lateral sides of the ridge.

Hereinafter, the present invention will be explained with reference to the drawings showing a specific example of the present invention.

Figure 2 shows a cross-sectional view of the double-glazed glass used in the present invention, in which two glass plates 1 and 1' have hollow parts 4 at predetermined intervals formed by spacers 2 made of flexible plastic material. They are spaced apart from each other to form a double-glazed glass 3.

A sealant (flexible sealant) 5 is filled around the outside of the spacer 2 to ensure sealing of the hollow portion 4.

In the double-glazed glass 3 of the present invention, since the spacer 2 is made of flexible plastic, it deforms when pressed, so the spacer 6 for preventing this deformation is attached to the peripheral edge of the double-glazed glass. It is installed between the glass plates 1 and 1'.

The above-mentioned spacer 2 is a pre-formed plastic spacer that is self-adhesive, flexible, allows easy bending of a part of the corner, and has appropriate elasticity to maintain bending. .

Examples include plastic spacers made from butyl rubber and polyimbutylene.

Furthermore, a drying agent for adsorbing moisture in the hollow part of the double-glazed glass, such as powdered synthetic crystalline zeolite, synthetic crystalline metal aluminosilicate, activated alumina, sintered silica, and sintered silica, is dispersed in the spacer. The mixture is used.

In addition, the above-mentioned spacing member 6 should preferably have a width X sufficient to maintain the gap between the multiple gas layers, little compressive deformation, sufficient rigidity, and high chemical and mechanical stability. Examples of the material include, but are not limited to, ethylene-vinyl acetate copolymer, polyvinyl chloride, nylon, polystyrene, bonpropylene, polycarbonate, and acrylic resin.

This spacing member 6 may be arranged outside the sealant layer 5 of the double-glazed glass 3 as shown in FIG. 2, or between the spacer 2 and the sealant layer 5, or If there is no sealant layer, it may be placed on the outside of the spacer 2 or, depending on the case, on the inside of the spacer 2.

The spacing member 6 is fixed to the peripheral edge of the double-glazed glass by using the adhesiveness of a spacer or a sealant layer, or by using an adhesive or the like.

Figures 3 to 6 are longitudinal cross-sectional views showing the construction state of a window employing the double-glazed window of the present invention using the above-mentioned double-glazed glass. The constituent glass plates are: 12 the window frame body, 13 the rim, 16 the lower frame, 17 the upper frame, 18 the double glazing 11 and the window frame body 12
Alternatively, an elastic member as a cushioning material is interposed between the rim 13, 14 is a spacer, and 15 is a spacing member.

The incorporation of the double-glazed glass window of the present invention will be explained based on FIG. 4. First, the double-glazed glass 10 shown in FIG. It can be assembled in a simple process of just fitting it into the main body 12.

The structure of the double-glazed window of the present invention uses a ridge 13 to attach the double-glazed glass to the window frame body 12 so as to actively apply the restoring force of the ridge 13 to fix it.
2. The rim 13 is designed to have a structure that allows this mechanism to be utilized.

The edge 13 used in the present invention has one side 19 (hereinafter referred to as the lateral side 19) that fits into the window frame body.

) and the other side 20 (hereinafter referred to as the vertical side 20) that sandwiches the end surface of the window glass from the side surface of the window glass.

), and both of these two sides are designed to fit into the window frame body in such a way that the window glass can be fixed to the window frame body by its own restoring force. There is.

FIG. 5 illustrates a typical example of the fitted state of the ridges of the present invention, in which the vertical sides 20 of the ridges 13 are in a state where their tips 21 are inclined inward, for example, the vertical sides 20 and the horizontal sides 19 Toga 9
It is bent at an acute angle of 0° or less, and the pressed edge 1
3 is inserted between the edges of the double-glazed glass 10, it is displaced to a nearly right angle position, and as a result, it actively exerts a restoring force on the double-glazed glass 10.

On the other hand, as shown in FIG.
3 is fitted into the window frame body 12, it is displaced in an arcuate manner toward the end surface side of the double-glazed glass 10, and the restoring force due to this displacement is used to push the double-glazed glass 10 into the window frame body. It is designed to be actively fixed at 12.

In this case, since a gap is required in which the horizontal side 19 can preferably be displaced inwardly into a convex surface, the gap a should desirably be designed to be larger than the thickness b of the horizontal side.

The fixing structure of double-glazed glass using the restoring force of the vertical and horizontal sides of the rim is not limited to the typical example described above.If a similar mechanism is distantly related, other structures can be adopted. The sides 20 may be bent inwardly to form a convex surface.

For example, as shown in Figure 6, the horizontal side 19 of the rim is bent in advance to form an outwardly curved convex surface, and when it is fitted into the window frame body, it is restored as shown in Figure 6a. It is also possible to fit it so that the force is applied in a nearly straight state.

In addition, various structures can be adopted for the fitting portion between the rim and the window frame body, but as shown in FIGS. The most preferable structure is that a protrusion 25 is formed on the upper surface of the horizontal side 19 of the ridge 13 so that the teeth 24 and the protrusion 25 fit together.

In this case, the teeth 24 of the protruding piece 23 of the window frame body 12 are
By forming it up to the tip 26, the fitting position of the ridge can be adjusted even if the thickness of the double-glazed glass changes.

The pitch width of the crests of the teeth 24 and the protruding portions 25 may be narrow if delicate adjustments are required, or wide if a large adjustment is required.

The above-mentioned rims are usually fitted into the window frame body that is arranged around the entire circumference of the double-glazed glass, so the rims can be of a two-piece type, a four-piece type, or a four-piece type so as to correspond to each side of the double-glazed glass. It may also be a multi-divided type.

In the present invention, the window frame body and the rim are generally made of metal or plastic, and aluminum profiles are particularly recommended.

Note that the material and thickness of the rim are selected to have a spring effect so that the double-glazed glass can be fixed with sufficient restoring force.

In addition, in the present invention, it is desirable that the restoring force imparted by the rim be uniform over the entire circumference of the glass plate, but depending on the purpose, it may be applied only partially. You can also give it some power.

According to the present invention, a maintenance member that does not deform even under compressive force is arranged on the peripheral edge of the double-glazed glass from the side surface thereof, so that the window can be fitted into the window frame body using the ridge having the above-mentioned restoring force. Due to the structure of the installation, the thickness of the double-glazed glass does not change during or after fitting, and a predetermined property can be obtained.

Furthermore, the thickness of the double-glazed glass does not change, and it can be firmly fixed by the rim, improving the dew point maintenance performance of the double-glazed glass and providing a solid structure.

As described above, according to the present invention, it is possible to use a press-edge method that simplifies the fitting of double-glazed glass, and the performance can be improved, so it is of great industrial value.
