The elastic holding member 21 for holding the double glazing h is attached to the double glazing h
The elastic holding member 21 was fitted and attached to the frame body 1 together with the peripheral edge portion of the.

[0003]

According to the above-mentioned conventional double glazing, since the sealing material is exposed, if it is carried by the time the sealing material is solidified, for example, it may become dirty on the hands or clothes. However, there is a risk that the sealing effect of the double glazing may be reduced, and in order to prevent them, the sealing material cannot be shipped until the sealing material is sufficiently hardened, resulting in low production efficiency.

Therefore, an object of the present invention is to solve the above problems and provide a double glazing which can be shipped immediately without curing.

A locking portion that can lock the elastic holding member is provided in a gap formed between the plurality of plate glasses at the peripheral edge of the multilayer glass body (corresponding to claim 1).

A second characteristic constitution is that the elastic holding member is
It is provided in the peripheral portion of the multilayer glass body in an adhesive state with the sealing material filled in the gap, and at least the adhesive portion of the elastic holding member with the sealing material is formed to be hard. (Corresponding to item 2).

A third characteristic configuration is that the elastic holding member is
Provided in a peripheral portion of the multilayer glass body in an adhesive state with the sealing material, at least at an adhesive portion of the elastic holding member with the sealing material, adhesiveness with the sealing material is higher than that of the elastic holding member body. A good intervening member is provided integrally (corresponding to claim 3).

[0008]

According to the first characteristic configuration of the double glazing of the present invention, the elastic holding member is provided at the peripheral portion of the double glazing body, and the elastic holding member can be locked to the double glazing body. Since the locking portion is provided in the gap in the peripheral portion of the double-glazing body, it is possible to cover the sealing material filled in the gap with the elastic holding member so as not to be exposed, and to be carried. It is possible to prevent the occurrence of problems such as the sticking of the sealing material on the hand and the sealing material being peeled off to lower the sealing effect. Furthermore, since the elastic holding member is locked to the multilayer glass body at the locking portion,
The elastic holding member can be attached to the peripheral edge portion of the double glazing body in a state where it is more difficult to disengage and displace as compared with the case where the peripheral edge portion of the double glazing body is simply covered. When storing, shipping or transporting glass,
Also, the peripheral edge portion of the multilayer glass can be protected by the elastic holding member throughout the mounting of the multilayer glass at the mounting site (corresponding to claim 1).

According to the second characteristic configuration, the elastic holding member is provided in a peripheral portion of the multilayer glass body in an adhesive state with the sealing material filled in the gap, and at least the elastic holding member is provided. Since the adhesive portion with the sealing material is formed to be hard, at least the adhesive portion is less likely to deform, for example, when an external force in the detaching direction acts on the local portion of the elastic holding member, the external force is applied to the adhesive portion. It can be dispersed in the entire part and can be received in a wide bonding range between the sealing material and the bonding part, and it becomes easy to prevent the elastic holding member from easily coming off from the multilayer glass body. Further, since the elastic holding member can be bonded to the multilayer glass body by the sealing material, it is not necessary to prepare another adhesive (corresponding to claim 2).

According to the characteristic constitution of the double glazing of the third aspect of the invention, the elastic holding member is provided on the peripheral portion of the double glazing body in an adhesive state with the sealing material, and at least the seal of the elastic holding member is provided. Since an intervening member having a better adhesiveness with the sealing material than the main body of the elastic holding member is integrally provided in the portion to be adhered to the material, the elastic holding member is provided with the same sealing material to form the double-glazing main body. Even if it is adhered to the sealing material, it becomes possible to exert a stronger adhesive force between the intervening member and the sealing material, as compared with directly bonding the sealing material and the elastic holding member. It is possible to improve the adhesiveness of the elastic holding member to the main body (corresponding to claim 3).

[0011]

Therefore, according to the double glazing of the present invention,
At the time of manufacturing, it is not necessary to cure the sealing material until it hardens, and manufacturing efficiency can be improved.
Corresponding to). In addition, the elastic holding member is less likely to come off, the protective function of the double glazing is improved, and the cost can be reduced because the bonding by the sealing material is possible (corresponding to claims 2 and 3). Furthermore, since it is not necessary to mount the elastic holding member at the site of mounting the double glazing, it is possible to improve the work efficiency of mounting the double glazing on the frame (claims 1, 2, 3). Correspondence).
