2. Description of the Related Art The usage rate of double glazing has been increasing from the viewpoint of energy saving and soundproofing, but the double glazing is attached to a sash by winding a glazing channel or by sealing with a backer. Is common. 4 and 5 exemplify the case of the former glazing channel, in which the glazing channels 9 are wound around the left and right and upper peripheral edges of the double-glazing unit 2 and are attached to the mounting openings of the upper frame 6 and the left and right frames 8. It is fitted and the lower side is attached to the lower frame 7 by the bead 10.

[0003]

In such a mounting method, works such as winding the glazing channel around the periphery of the double glazing and cutting the corners and abutting the glazing channels occur, which takes a lot of man-hours. In particular, since double glazing has a larger total thickness than ordinary glass, it takes a lot of time and effort to wind the glazing channel during assembly.

Further, since these glazing channels and beads inevitably have many exposed portions exposed to the outside air, replacement is necessary because the glazing channels and the like shrink or crack due to aging after construction.
The latter sealing method takes more time and labor for the on-site sealing work, and there is a concern that the seal may be broken after the construction.

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

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

That is, according to the present invention, a channel-shaped reinforcing material that can surround the peripheral portion of the double glazing, an inner soft portion that comes into contact with the double glazing and the glass and the sash come into contact with the inner soft part. An attachment having an outer soft part that seals between the double glazing and the sash, and a soft material provided on the reinforcing material so as to cover the open end of the reinforcing material is attached to the peripheral portion. Provided is an attached double glazing having an attachment.

In the present invention, metal or synthetic resin is used as the reinforcing material. These reinforcing materials have a U-shaped cross section when applied to the double glazing and surround the peripheral edge of the double glazing. In the case of metal reinforcement,
Before and after forming the soft material inside and outside, it is bent into a U-shaped channel, and by fitting the edge part of the double glazing into this U-shaped opening, it can be easily attached to the double glazing. ing. 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 the inner soft portion and the outer soft portion integrally provided on the reinforcing material is a Shore A hardness 60 of vinyl chloride resin or acrylic resin.
Most preferred is about 70 degrees. The selected soft material is continuously and integrally formed on the inner surface of the reinforcing material facing the double glazing and a part or the whole of the portion engaging with the shoji frame or sash. In this case, the shape of the soft material is not particularly limited, but the outer soft part is mounted and fixed to the shoji frame or the like so that the double-layer glass is firmly and watertightly obtained, and especially an edge portion exposed to the outside is preferable. It is good to devise it to be small.

[0010]

1 and 2 show a general embodiment of the present invention, in which a soft material 50 consisting of an inner soft part 4 and an outer soft part 3 is provided at the peripheral edge of a double glazing. The attachment 1 mainly made of the reinforcing material 5 integrated with each other is fitted and attached to each side of the multi-layer glass to facilitate attachment and assembly to the sash frame.

An inner soft part 4 made of, for example, vinyl chloride resin is continuously provided in the longitudinal direction on the inner surface of the reinforcing member 5 having a U-shaped cross section. The main function of the inner soft part is to prevent the reinforcing material 5 from directly contacting the glass. Normally, the inner surface of the channel-shaped reinforcing material 5 facing the glass has a convex shape in the longitudinal direction at a predetermined interval. It may be formed as a piece. In this way, it is possible to prevent the sash frame of the double glazing from coming off from the mounting opening.

Further, the outer soft portion 3 made 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 water-tightness when the multi-layer glass with the attachment is fitted to a frame or a sash. In the illustrated preferred embodiment, the outer soft portion is integrally formed on the outer surface of the channel-shaped reinforcing member 5, and the reinforcing member 5 is formed by a part thereof.
The open end is covered and the outer soft lip allows the glass to be sealed.

The multi-layer glass with the attachment can be obtained by applying the attachment 1 to the peripheral portion of the multi-layer glass 2. This deposition may be carried out on the spot before the double glazing is attached to the frame or sash, but it is usually preliminarily attached to the double glazing in a separate step.

That is, the attachment 1 is replaced with the double glazing 2.
Cut to fit the peripheral dimensions of the glass and then fit the edges of the double glazing into the openings in this attachment. This attachment is fixed to the peripheral edge of the double glazing by suitable friction between the lips 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 double glazing with the attachment of FIG. 1 is attached to a frame or the like. A block 8 is laid on the bottom of the attachment opening of the lower frame 7 to support the lower end of the double glazing, and is firmly clamped by the lower frame from both sides of the attachment via the outer soft parts 3. In this way, as shown in the figure, the outer flexible portion 3 seals between the lower frame 7 of the sash and the double glazing. In addition, 1 in the figure
Block 1 is for removing rainwater that has entered the lower frame
It is a hole provided in the.

FIG. 6 shows a double-glazing unit with an attachment, in which the outer soft part has another preferred form. In this example, the outer soft part 3 has a locking part 13 to the tip 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 face of the double glazing with the attachment can be fixed at a predetermined position in the mounting opening of the frame. In this way, even when an external force is applied to the double glazing 2 and the attachment or the like, the double glazing does not go deep into the mounting opening of the frame, and the double glazing can be prevented from shifting in the sash. This is particularly effective when the block is not inside the mounting opening of the frame, such as the upper frame and the frame.

The reinforcing material 5 is preferably provided with drainage holes 20 so as to be scattered in the longitudinal direction of the reinforcing material 5, as shown in FIG. This is effective when the double glazing with attachment is attached to the lower frame, and when water such as rainwater enters from between the double glazing and the inner soft part or between the double glazing and the attachment, etc. This is because it is possible to prevent the end face of the double glazing glass from being exposed to moisture for a long time. As for the inner soft portion 4, as shown in FIG. 6, the inner soft portion 4 is provided at a position corresponding to the glass portion of the double glazing on the inner bottom surface of the U-shaped cross section of the reinforcing material 5. It is effective to prevent the deterioration of the double glazing due to the rainwater and the like and to prevent the double glazing from being fogged by providing a gap between the reinforcing material 5 and the spacer so that the spacer and the spacer of the double glazing 2 do not come into contact with each other. .

FIG. 3 shows another embodiment of the present invention, in which the attachment 1 is generally flat as a whole by providing a folding groove corresponding to the thickness of the double glazing, but the attachment 1 can be easily formed. The reinforcing material 5 is formed of a hard synthetic resin that can be bent, and the inner soft portion 4 and the outer soft portion 3 are provided on the inner and outer surfaces of the reinforcing material after bending,
Further, in a selected area on the inner surface, the double-sided adhesive tape 12
Alternatively, it is provided with an adhesive layer.

In the double-layer glass with attachment, the reinforcing material is bent from both sides in a state where the attachment is pressed against the edge of the double-layer glass, and the double-sided adhesive tape adheres to the glass surface.

[0020]

As described above, according to the present invention, since the attachment is attached to the peripheral portion of the double glazing as described above, it can be mounted on the sash frame as it is, compared with the conventional glazing channel method or 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, shrinkage of the soft material is prevented, the quality after assembly is stable, and gaps at the corners can be prevented.

Furthermore, since the soft material of the attachment is stopped on the upper surface of the sash frame, 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. it can.
