Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to double-glazed glass used in show cases and the like.

(Prior art) Conventionally, although it is not yet publicly known, Fig. 2a
As shown in FIG.
The applicant has proposed a double-glazed glass in which a frame-shaped spacer 2 formed of a hollow transparent member is interposed between the peripheral edges of the window b, and a desiccant 3 is housed within the spacer 2 (Showa 1959 Utility Model Registration Application No. 111600).

(Problems to be Solved by the Invention) In the conventional example, as shown in FIG. Since the spacer 2 is made of transparent resin, the viewing range of the corner part of the case body 4 is large, but when the desiccant 3 is stored in the entire spacer 2, the corner part is hidden by the desiccant 3. ,
This has a problem in that it is not possible to enlarge the viewing range at the corner portions. In addition, when assembling double-glazed glass, spacers 2 are attached to the glass plate 1 according to the length of each side of the glass plates 1a and 1b.
Although it is attached in a frame shape to the periphery of the glass plates 1a and 1b, it takes time and effort to position the spacer 2 to the glass plates 1a and 1b and to join the spacers 2 together, resulting in a problem that production efficiency is not good. .

The present invention was devised in view of the above-mentioned problems, and its purpose is to provide double-glazed glass whose transparency is not impaired by the stored desiccant and which can be easily assembled. There is a particular thing.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a frame-shaped spacer formed of a hollow transparent member between the peripheral edges of two opposing rectangular glass plates. In the double-glazed glass in which a desiccant is housed in the spacer, the spacer is composed of a side member corresponding to the side portion of the glass plate and a corner member corresponding to the corner portion, and the corner member is It has connecting portions inserted into the ends of the side members at both ends, and the desiccant is stored only within the corner members.

(Function) According to the double-glazed glass of the present invention, the desiccant that absorbs moisture between each glass plate is stored in the corner members of the spacer, so there is no desiccant in the side members, and the double-glazed glass is The transparency of the edges of the layered glass is not impaired. Further, the spacer is assembled into a frame shape by inserting the connecting portions of the corner members into the ends of the side members.

(Embodiment) FIG. 1, FIG. 3, and FIG. 4 show an embodiment of the present invention, and constituent parts equivalent to those of the conventional example are denoted by the same reference numerals. That is, 1a and 1b are glass plates, and 3 is a desiccant.

In the figure, 10 is a spacer, and the glass plate 1
It is composed of side members 20 corresponding to the side portions a and 1b and corner members 30 corresponding to the corner portions.

For the side member 20, a linear spacer equivalent to that of the conventional example is used. The side member 20 includes a transparent synthetic resin member 21 that is hollow and has a hexagonal cross section, and a stainless steel member 22 that covers the outside of the synthetic resin member 21. In addition, synthetic resin member 2
1 has a groove 21 extending in its length direction in the center in the width direction.
a is provided to communicate the inside of the synthetic resin member 21 with the space 1c between each glass plate 1a, 1b. In addition, 23 is a sealing member filled in the periphery of the glass plates 1a and 1b.

The corner member 30 is made of transparent synthetic resin,
It consists of a spacer part 31 in the shape of a hollow box bent at a right angle, and connecting parts 32 in the shape of a hollow cylinder extending from both ends of the spacer part 31, respectively. In addition, the spacer part 3
1 and the connecting portion 32 are in internal communication with each other, and the outer shape of the connecting portion 32 is formed into a hexagonal cross-section that can be fitted into the open end of the side member 20. Furthermore, each connecting portion 32 has an open end, and
It has a lid 33 that opens and closes this opening 32a, and the desiccant 3 is stored in the connecting part 32 and the spacer part 31 from the opening 32a. Further, a ventilation hole 34 corresponding to the groove 21a of the side member 20 is provided on one side of each connecting portion 32, and the space 1c between each glass plate 1a, 1b is communicated with the inside of the connecting portion 32.

In this embodiment, when assembling double-glazed glass, first connect each connecting portion 32 of the corner member 30 to the side member 2.
0 to connect the side member 20 and corner member 30. As a result, a frame-shaped spacer 10 is assembled, and this spacer 10 is attached to each glass plate 1.
Double glazing is completed by interposing it between a and 1b.

In this way, according to the double-glazed glass of this example,
Since the spacer 10 is composed of a side member 20 and a corner member 30, and the desiccant 3 is housed in the corner member 30, the transparency of each side of the double-glazed glass, that is, the corner of the case body 4 is impaired. It never happens. Therefore, the inside of the show case main body 4 can be seen sufficiently even from the corner portion, and the effect of displaying products can be improved.
In addition, by inserting each connecting portion 32 of the corner member 30 into the open end of the side member 20, the frame-shaped spacer 1
0 can be assembled easily, so the double glazing itself can be assembled very easily. Furthermore,
Since each connecting portion 32 is inserted into the open end of the side member 20, strength and airtightness can also be improved.

(Effect of the invention) As explained above, according to the double-glazed glass of the present invention, the transparency of each side of the double-glazed glass is not impaired, so when the double-glazed glass is used for a show case, the inside can be seen from the corner of the case body, improving the product display effect. Furthermore, since the frame-shaped spacer can be easily assembled, the double-glazed glass itself can be assembled extremely easily, and its strength and airtightness can be improved.
