Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a double glazing with an attachment.

[0002]

2. Description of the Related Art The use rate of double glazing is increasing from the viewpoint of energy saving and soundproofing. The mounting of such double glazing on a sash is performed by winding a glazing channel or sealing by inserting a backer. Is common. 4 and 5 exemplify the former case of the glazing channel, in which the glazing channel 9 is wound around the left and right and upper peripheral edges of the double-glazed glass 2, and the upper glazing 6 and the left and right slats 8 are attached to the mounting openings. The lower side is attached to the lower frame 7 by a bead 10.

[0003]

In such a mounting method, operations such as winding of the glazing channel around the periphery of the double-glazed glass, cutting of the corner portion, and butting of the corner portions are required. In particular, since the total thickness of the multi-layer glass is larger than that of ordinary glass, winding the glazing channel during assembly is very troublesome.

In addition, since these glazing channels and beads have an increased number of exposed portions that come into contact with the outside air, the glazing channels and the like shrink or crack due to aging after construction, so that replacement is necessary.
In the latter sealing method, not only is it more time-consuming to perform on-site sealing work, but also there is a concern that the seal may be broken after construction.

[0005] As described above, in the conventional mounting structure of the double glazing, the glazing channel and the sealing material are interposed between the double glazing and the shoji sash, which takes a lot of man-hours for the assembling work and also requires maintenance after the work. There are drawbacks such as.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to replace glazing channels and seals and to improve workability and quality. Specifically, the function of the glazing channel or sealing material is integrated into the double-glazed glass, and a glazing attachment is added to the double-glazed glass in order to easily incorporate the double-glazed glass. .

That is, the present invention provides a channel-shaped synthetic resin reinforcing material capable of surrounding the periphery of a double-glazed glass, and an internal soft material integrally provided on the inner surface of the reinforcing material facing the double-glazed glass. The present invention also provides a double-glazed glass with an attachment in which an attachment made of an external soft material integrally provided on an outer surface engaging with a sash is attached to a peripheral edge portion.

In the present invention, the reinforcing material is made of a synthetic resin, has a U-shaped cross section when applied to the double glazing, and surrounds the periphery of the double glazing. In addition, you may make it a U-shaped cross section so that it may be bent when it adheres to the peripheral part of a double glazing.

In the present invention, the inner soft material and the outer soft material integrally provided on the inner and outer surfaces of the reinforcing material include:
Shore A hardness of vinyl chloride resin or acrylic resin 60 to 7
Most preferably about 0 °. The soft material selected is
The reinforcing member is continuously and integrally formed on the inner surface facing the double-glazed glass and a part or the whole of the outer surface engaging with the shoji frame or the sash. In this case, the shape of these soft materials is not particularly limited, but the external soft material is attached and fixed to the shoji frame or the like so that the double-layer glass is firmly and watertightly obtained.
In particular, it is preferable that the edge exposed to the outside is reduced as much as possible.

[0010]

FIG. 1 and FIG. 2 show a general embodiment of the present invention, in which an attachment 1 having a reinforcing material 5 as a main material at the periphery of a double-layer glass is provided. Are fitted and mounted on each side of the sash frame to facilitate the mounting and assembly on the sash frame.

On the inner surface of the reinforcing member 5 having a U-shaped cross section, an internal soft material 4 made of, for example, a vinyl chloride resin is provided continuously in the longitudinal direction. The main function of the internal soft material is to prevent the reinforcing material 5 from directly hitting the glass. Usually, the inner surface of the channel-shaped reinforcing material 5 facing the glass has a convex shape at a predetermined interval in the longitudinal direction. What is necessary is just to form as a piece. In this way, it is possible to prevent the double-glazed glass from falling out of the mounting opening of the sash frame.

On the other hand, an outer soft material 3 of the same material is integrally fixed to the outer surface of the reinforcing material 5. In this case, the form of the outer soft material 3 is not particularly limited, but it is necessary to sufficiently obtain watertightness when the double-glazed glass with attachment is fitted to a frame or sash. In an exemplary preferred embodiment, this external soft material is integrally formed on the outer surface of the channel-like reinforcing material 5, a part of which covers the open end of the reinforcing material 5, and a glass lip of the external soft material is used. Can be sealed.

The double-glazed glass with an attachment can be obtained by attaching the attachment 1 to the periphery of the double-glazed glass 2. This deposition may be performed on the spot before the double-glazing is attached to the frame or sash, but usually, the double-glazing is attached to the double-glazing in a separate step.

That is, the attachment 1 is made of
Then, the edge of the double glazing is fitted into the opening of the attachment. This attachment is secured to the periphery of the double glazing by suitable friction between the lip of the inner soft material 4 and the outer soft material 3 and the glass.

FIG. 2 shows a state of the lower frame 7 when the double glazing with attachment of FIG. 1 is mounted on a frame or the like. A block 8 is laid on the bottom of the mounting opening of the lower frame 7 to support the lower end of the double-glazed glass, and is firmly held by the lower frame via the external soft material 3 from both sides of the attachment. In the figure, reference numeral 11 denotes a hole provided in the block 8 for extracting rainwater that has entered the lower frame.

FIG. 6 shows a double-glazed glass with an attachment in which the external soft material has another preferred form. In this example, the outer soft material 3 has a locking portion 13 to the leading edge 17 of the mounting opening of the sash frame. By locking the locking portion 13 to the upper edge 17 of the sash frame, the end surface of the multi-layer glass with attachment can be fixed at a predetermined position in the mounting opening of the frame. Thus, even when an external force is applied to the double-glazed glass 2 and the attachment, the double-glazed glass does not penetrate deep into the mounting opening of the frame, and the double-glazed glass can be prevented from shifting in the sash. This is particularly effective when the block is not in the mounting opening of the frame, such as an upper frame or a frame.

The reinforcing member 5 is preferably provided with drainage holes 20 scattered in the longitudinal direction of the reinforcing member 5 as shown in FIG. This is effective when the double glazing with attachment is attached to the lower frame, and when moisture such as rainwater invades from between the double glazing and the internal soft material or between the double glazing and the attachment. This is because it is possible to prevent the end face of the double glazing from being exposed to moisture for a long time. The provision of the inner soft material 4 in the reinforcing material 5 so as not to contact the spacer of the double glass 2 as shown in FIG. It is effective for prevention.

FIG. 3 shows another embodiment of the present invention, in which the attachment 1 is usually generally flat by providing a folding groove corresponding to the thickness of the double-glazing, for example. A reinforcing material 5 is formed of a foldable hard synthetic resin, and an inner soft material 4 and an outer soft material 3 are provided on inner and outer surfaces of the reinforcing material after bending, respectively.
Further, a double-sided adhesive tape 12 is applied to a selected area on the inner surface.
Alternatively, an adhesive layer is provided.

The double-glazed glass with an attachment is obtained by bending a reinforcing material from both sides in a state where such an attachment is pressed against the edge of the double-glazed glass and bonding the reinforcing material to the glass surface with a double-sided adhesive tape.

[0020]

As described above, according to the present invention, since the attachment is attached to the peripheral portion of the double-glazed glass, it can be mounted on the sash frame as it is, and compared with the conventional glazing channel method or the sealing method. The workability of assembling sash frames and glass is greatly reduced.

Further, since the soft material is fixedly attached to the attachment, the shrinkage of the soft material is prevented, so that not only the quality after assembling is stabilized, but also a gap at the corner can be prevented.

Furthermore, the soft material of the attachment is stopped on the upper surface of the sash frame, and the area of the soft material exposed to the outside can be made smaller than that of the conventional method, thereby preventing or reducing shrinkage and cracking due to the influence of sunlight. it can.
