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 not only takes more time and labor for the on-site sealing work, but there is a concern that the seal may be broken after the construction.

As described above, in the conventional structure for mounting double glazing, 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 assembly and requires maintenance after the construction. There are drawbacks such as

1 and 2 show an attachment.
It shows the attached double glazing , and the attachment 1 mainly composed of the reinforcing material 5 is fitted and attached to each side of the double glazing 2 on the peripheral edge of the double glazing 2, and is attached and assembled to the sash frame. It makes it easy.

An inner soft material 4 made of vinyl chloride resin, for example, is continuously provided in the longitudinal direction on the inner surface of the reinforcing material 5 having a U-shaped cross section. The main function of the inner soft material 4 is to prevent the reinforcing material 5 from directly contacting the glass. Normally, the inner soft surface of the channel-shaped reinforcing material 5 is convex on the inner surface facing the glass at a predetermined interval in the longitudinal direction. It may be formed as a piece. In this way, it is possible to prevent the sash frame of the double glazing 2 from coming off from the mounting opening.

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 ensure sufficient water tightness when the double glazing with the attachment is fitted to the frame or the sash. In the illustrated preferred embodiment, the outer soft material 3 is integrally formed on the outer surface of the channel-shaped reinforcing material 5, and a part of the outer soft material 3 covers the open end portion of the outer soft material 3, and the lip of the outer soft material 3 is formed. The glass can 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 prior to mounting the double glazing 2 on the frame or sash, but it is usually preliminarily mounted on the double glazing 2 in a separate step.

That is, the attachment 1 is replaced with the double glazing 2.
It is cut according to the peripheral dimension of, and then the edge portion of the double glazing 2 is fitted into the opening portion of the attachment 1. The attachment 1 is fixed to the peripheral edge portion of the double glazing 2 by an appropriate 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 multi-layer glass with the attachment of FIG. 1 is attached to the 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-glazing unit 2 and is firmly clamped by the lower frame from both sides of the attachment 1 via the external soft material 3. Reference numeral 11 in the figure denotes a hole provided in the block 8 for draining rainwater that has entered the lower frame.

FIG. 6 shows a double glazing with an attachment in which the outer soft material 3 has another preferable form.
In this example, the outer soft material 3 has a locking portion 13 to the tip edge 17 of the mounting opening of the sash frame. Since the locking portion 13 is locked 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 external force is applied to the double glazing 2 and the attachment 1, etc., the double glazing 2 does not go deep into the mounting opening of the frame, and the double glazing 2 is prevented from shifting in the sash. it can. 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 an attachment is attached to the lower frame, and water such as rainwater enters from between the double glazing 2 and the inner soft material 4 or between the double glazing 2 and the attachment. When I did
This is because it is possible to prevent the end face of the double glazing 2 from being exposed to moisture for a long time. In addition, as shown in FIG. 6, the inner soft material 4 is provided on the reinforcing material 5 so as not to come into contact with the spacer of the double glazing 2, so that the deterioration of the double glazing 2 due to the rainwater or the like or the double glazing 2 It is effective in preventing fogging.

FIG. 3 shows another embodiment of the present invention, in which the attachment 1 is normally flat as a whole by providing a folding groove corresponding to the thickness of the double glazing 2, but it is easy. The reinforcing material 5 is formed of a hard synthetic resin that can be bent into, and the inner soft material 4 and the outer soft material 3 are provided on the inner and outer surfaces of the reinforcing material 5 after bending,
Further, in a selected area on the inner surface, the double-sided adhesive tape 12
Alternatively, an adhesive layer is provided.

The multi-layer glass with an attachment is one in which the reinforcing material 5 is bent from both sides in a state where the attachment 1 is pressed against the edge portion of the multi-layer glass 2 and is adhered to the glass surface with a double-sided adhesive tape. .

[0020]

As described above, according to the present invention, since the attachment is adhered 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, contraction of the soft material is prevented, the quality after assembly is stable, and gaps at the corners can be prevented.

Further, 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 made smaller than that of the conventional method, so that shrinkage and cracking due to the influence of sunlight can be prevented or reduced. it can.
