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 method of attaching such a double-glazed glass to a sash is generally a method of winding a glazing channel or a method of sealing with a backer. 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, the work of winding the glazing channel around the periphery of the double-glazed glass and the work of cutting the corners and butting them together are required. I have. In particular, since the total thickness of the multi-layer glass is larger than that of ordinary glass, winding the glazing channel at the time of assembly is very troublesome.

[0004] In addition, these glazing channels and beads have a large number of exposed portions that come into contact with the outside air, so that the glazing channels and the like shrink or crack due to aging after construction, and thus need to be replaced.
The latter sealing method requires more time and effort in the on-site sealing operation, and there is a concern that the seal may be broken after the application.

[0005] As described above, in the conventional mounting structure of a double-glazed glass, the glazing channel and the sealing material are interposed between the double-glazed glass and the shoji screen, so that the assembling process takes a lot of man-hours and requires maintenance after the mounting. There are drawbacks such as becoming.

[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, glazing attachments (hereinafter simply referred to as “attachments”) are added to the double-glazed glass to consolidate the functions of the glazing channels or sealing materials in the double-glazed glass and to facilitate the installation of the double-glazed glass. It is a structure that does.

That is, the present invention provides a channel-shaped reinforcing material having a U-shaped cross section consisting of only a bottom portion and an upright wall portion erected from both ends of the bottom portion and capable of surrounding the periphery of the double-glazed glass, Having an inner soft portion abutting on the glass relative to the insulated glass and an outer soft portion abutting on the insulated glass and the insulated glass sash to seal between the insulated glass and the insulated glass sash; A glazing attachment comprising: an inner surface portion of the reinforcing member facing the double-glazed glass and a soft material provided on a part of a portion engaging with the sash so as to cover the open end of the standing wall portion. Accordingly, the present invention provides a double-glazed glass with an attachment, in which an attachment mainly composed of a reinforcing material is attached to a peripheral portion of the double-glazed glass.

In the present invention, a metal or a synthetic resin is used as a reinforcing material. These reinforcing materials have a U-shaped cross section when applied to the double glazing, and surround the periphery of the double glazing. In the case of metal reinforcement,
Before or after the formation of the soft material inside and outside, it is bent into a U-shaped channel, and the edge of the double-glazed glass is fitted into this U-shaped opening, so that it can be easily attached to the double-glazed glass. I have. In the case of a synthetic resin reinforcing material, it may be bent when it is attached to the peripheral portion of the double glazing.

In the present invention, the soft material having an inner soft portion and an outer soft portion provided integrally with the reinforcing material is most preferably a vinyl chloride resin or an acrylic resin having a Shore A hardness of about 60 to 70 degrees. The selected soft material is continuously and integrally formed on the inner surface of the reinforcing material facing the double-glazed glass and a part of the portion engaging the sash. In this case, the shape of the soft material is not particularly limited, but the outer soft portion is attached and fixed to the sash so that the double glazing is firmly and watertightly obtained, and particularly the edge exposed to the outside is made as small as possible. It is better to devise.

[0010]

1 and 2 show a general embodiment of the present invention. A soft material 50 comprising an inner soft portion 4 and an outer soft portion 3 is provided on the periphery of a double-layer glass. The attachment 1 mainly composed of the reinforcing material 5 integrated with is fitted to each side of the multi-layer glass to facilitate the mounting and assembly on the sash frame.

The reinforcing member 5 includes a bottom portion 5a and a bottom portion 5a.
Is a channel having a U-shaped cross section composed of only the upright wall portions 5b, 5b provided upright from both ends. Reinforcement 5
On the inner surface of the inner soft portion 4 made of, for example, vinyl chloride resin
Are provided continuously in the longitudinal direction. The main function of this inner soft part is to keep the reinforcement 5 from directly hitting the glass, usually a channel-like reinforcement 5
What is necessary is just to form as a convex piece in the longitudinal direction with a predetermined space | interval on the inner surface facing glass. In this way, it is possible to prevent the double-glazed glass from falling out of the mounting opening of the sash frame.

Further, an outer soft portion 3 of the same material is integrally fixed to the reinforcing member 5. In this case, the outer soft part 3
The form is not particularly limited, but it is necessary to ensure sufficient watertightness when the double-glazed glass with attachment is fitted to a sash. In an exemplary preferred embodiment, the outer flexible portion is integrally formed on the outer surface of the channel-shaped reinforcement 5, a part of which covers the open end of the reinforcement 5, and the lip of the outer flexible portion forms a glass. And the sash 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 prior to attaching the double glazing to the sash,
Usually, it is attached to the double glazing in a separate process in advance.

That is, the attachment 1 is made of
Is cut in accordance with the peripheral dimension of the glass, and then the edge of the double-layer glass is fitted into the opening of the attachment 1. The attachment 1 is fixed to the periphery of the double-glazed glass by appropriate friction between the lip of the inner soft part 4 and the outer soft part 3 and the glass.

FIG. 2 shows a state of the lower frame 7 when the multi-layer glass with attachment of FIG. 1 is mounted on a frame or the like.
A block 8 is laid at 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 outer flexible portion 3 from both sides of the attachment.
Thus, the space between the lower frame 7 of the sash and the double glazing is sealed by the outer soft portion 3 as shown in the figure. 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 outer soft part has another preferred form. In this example, the outer flexible part 3 has a locking part 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 the upper 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 inner soft part 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. Further, as shown in FIG. 6, the inner soft portion 4 is provided with the inner soft portion 4 at a position corresponding to the glass portion of the multi-layer glass on the inner side surface of the bottom surface portion of the reinforcing material 5 as shown in FIG. Providing a gap between the reinforcing material 5 and the spacer so that the spacer of the glass 2 does not come into contact is effective in preventing the deterioration of the double-glazed glass due to the above-mentioned rainwater or the like and preventing the double-glazed glass from fogging.

FIG. 3 shows another embodiment of the present invention. The attachment 1 is usually generally flat but easily formed by providing a fold groove corresponding to the thickness of the double-layer glass. A reinforcing material 5 is formed of a foldable hard synthetic resin, and an inner soft portion 4 and an outer soft portion 3 are respectively provided on the inner and outer surfaces of the reinforcing material after bending, and a double-sided adhesive is formed on a selected region of the inner surface. It is provided with a tape 12 or an adhesive layer.

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 the sash frame and glass is greatly reduced.

Further, since the soft material is fixedly integrated with 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.

Further, 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 reduced as compared with the conventional method, so that shrinkage and cracking due to the influence of sunlight can be prevented or reduced. .
