Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a spacer made of synthetic resin, which is interposed between the peripheral portions of two glass plates to form a double glazing.

[0002]

[Prior art]

 Conventionally, double glazing has been widely used in which appropriate intervals are provided between two glass plates in order to improve the heat insulation performance of various windows and prevent dew condensation on the glass surface. Then, as one means for forming such a double glazing, a spacer made of aluminum or synthetic resin is interposed between the peripheral portions of two glass plates.

Usually, such a spacer for double glazing is formed by combining four linear members arranged on the peripheral edge of the glass plate and four corner members connecting these members. ing. Further, the linear member is formed in a hollow shape, and the inside thereof is filled with a desiccant for preventing the occurrence of dew condensation on the inner surface of the multilayer glass.

[0004]

[Problems to be solved by the device]

 However, the conventional spacer for double glazing has a disadvantage that its shape is complicated and that the fixing of the linear member and the corner member is troublesome.

Further, when using wire-cored glass in a fire door, it is necessary to waterproof the cut end of the glass to prevent the wire rod from rusting due to rain water or dew condensation water. The workability was poor because the waterproofing process and the work of assembling the glass in multiple layers had to be performed separately.

Therefore, an object of the present invention is to provide a spacer for double glazing, which has a simple shape and is easy to manufacture, and can be easily assembled and assembled with a glass plate.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the spacer for double glazing of the present invention is a spacer made of synthetic resin, which is interposed between the peripheral portions of two glass plates to form a double glazing. A hard main body part disposed between two glass plates and a covering side extending from one side of the main body part to cover the end faces of both glass plates are integrally formed, and both side wall parts of the main body part are formed on both sides. It is characterized in that both the glass plates are fixed to each other by an adhesive tape to hold them at a predetermined interval, and the end sides of both the glass plates are covered with the covering side.

[0008]

[Work]

 The double-glazing spacer with the above structure has a rigid main body that is placed between two glass plates and a covering edge that covers the end faces of the glass plates, so it is positioned when the glass plate is assembled. It is also easy to perform, and for the waterproof treatment of the cut part of the mesh-cored glass when using the mesh-cored glass on the outside, it is enough by forming the covered side integrally with the main body part with soft synthetic resin. Can correspond to.

【Example】

 Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. First, FIG. 1 shows the first embodiment of the present invention. This spacer 10 for double glazing has a main body 11 and a cover side 12 integrally molded of hard polyvinyl chloride. A drying agent 13 for preventing dew condensation on the inner surface of the double glazing is provided inside the portion 11.

The desiccant 13 is embedded in a granular desiccant at the same time when the spacer 10 for double glazing is drawn out and molded, or a desiccant is attached after the molding to form the spacer 10 for double glazing. It is provided integrally.

The above-mentioned spacer 10 for double glazing is cut at 45 ° diagonally at both ends according to the size of the glass plate 1, and the cut surfaces are joined by welding or a suitable adhesive to form a four-sided structure. Both side surfaces of the main body portion 11 and the peripheral portions of both glass plates 1 are bonded together via double-sided adhesive tapes, and the cut sides of both glass plates 1 are covered by the covering sides 12 on both sides of the main body portion.

The spacer 10 for double glazing having the above-mentioned structure can surely determine its position by bringing the covered side 12 into contact with the cut surfaces of both glass plates 1, and the mounting work is easy. Moreover, since the desiccant 13 is integrated, it is not necessary to separately prepare a desiccant.

FIG. 2 shows a second embodiment of the present invention, in which the main body portion 21 of the spacer 20 for double glazing has a hollow shape, and the hollow portion is filled with a granular desiccant 22. It is a thing. On the inner peripheral side of the main body portion 21, there are formed through holes 23 or slits having a particle size smaller than that of the desiccant 22, so that the air between the glass plates 1 and 1 can contact the desiccant 22.

Even when the desiccant 22 is formed so as to be filled later, the spacer 20 for double glazing can be easily attached to the glass plate 1, 1 by the covering sides 24 extending from the main body 21 to both sides. Can be attached to

FIG. 3 shows a third embodiment of the present invention, and shows a structure suitable for the case where the mesh glass 2 is used on the outside. The spacer 30 for double glazing has a main body 31 made of a hard synthetic resin and a cover side 32 made of a soft synthetic resin, which are integrally molded. A desiccant not shown can be provided as shown in FIG.

By forming the coated side 32 with the soft synthetic resin in this way, it is possible to deal with the case where the cut surface of the reticulated glass 2 is subjected to a rust preventive treatment with a butyl tape or a rust preventive paint.

It is not necessary to use the same spacer for all four circumferences of the glass plate, and it is possible to use them in an appropriate combination.

[0018]

[Effect of device]

 As explained above, the spacer for double glazing of the present invention should be manufactured at low cost because the hard main body part that is placed between the glass plates and the covering side that covers the end face are integrally formed with synthetic resin. In addition to being easy to assemble, it is easy to assemble, and it is possible to easily form double glazing.
