BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacer for a double glazing.

[0002]

2. Description of the Related Art A double glazing in which a decorative member such as a lattice is enclosed is known. Conventionally, as a structure for attaching the decorative member, as exemplified in Japanese Utility Model Application Laid-Open No. 61-35899, the decorative member is temporarily attached to a frame, then the frame is inserted between glass plates, and then the frame is inserted. A multi-layer vitrification is achieved by contacting a metal spacer so that no gap is formed around the periphery of the glass. On the other hand, there is no known double-glazed glass containing a decorative member using a string-shaped spacer made of a synthetic resin having adhesive properties as a spacer.

[0003]

As described above, in the conventional spacer structure, the spacer and the frame body to which the decorative member is attached are separated and independent, and they are combined in the process of assembling the double-glazed glass. It is extremely difficult to eliminate the gap between the frame and the spacer during assembly.
Furthermore, when the spacer is retrofitted around the spacer, it is substantially difficult to align the center of the frame with the spacer, particularly when an adhesive layer is provided on the side surface of the spacer.

[0004]

SUMMARY OF THE INVENTION The present invention provides a spacer for a double glazing which can solve these problems.

That is, the present invention is a spacer for a double-glazed glass containing a decorative member such as a lattice, comprising a spacer body having a desiccant therein and a frame body for attaching and fixing the decorative member. Provided is a spacer for a double glazing in which a drying agent in a spacer main body is provided with a ventilation hole through which the desiccant in the spacer body is absorbed through the frame so as to be integrally formed by being locked to the outside of the frame. Is what you do. Also, in the present invention, a plurality of glass plates are spacers.
A hollow layer is formed between the glass plates spaced apart from each other.
A multi-layer glass in which a decorative member such as a lattice is disposed in the hollow layer.
A spacer having a desiccant therein.
Frame for attaching and fixing the decorative body and the decorative member
Body and the spacer body is locked outside this frame
And integrated into the main part of the frame
Vent holes for the desiccant to absorb moisture through this frame
So that the frame is disposed on the hollow layer side
The spacer is interposed between a plurality of glass plates
It is intended to provide a double glazing characterized by the above.

In the present invention, the spacer body is a string-shaped spacer made of an adhesive synthetic resin such as thiochol, urethane, or silicone rubber, or a long rectangular section having a rectangular cross section formed by extruding aluminum or molding an aluminum plate. A metal spacer as a body can be used as appropriate.
These spacers have a desiccant therein. In the case of a string-shaped spacer, it is mixed in a synthetic resin having adhesiveness, and in the case of a metal spacer, it is loaded into the cylindrical hollow portion described above. Further, the feature of the spacer body is provided with a locking end for structural integration with a frame described later.

On the other hand, the frame is usually a long body made of metal such as aluminum, and a screw hole for mounting and fixing a decorative member in advance and a desiccant in the spacer body absorb moisture through the frame. Ventilation holes are formed. These holes may be provided individually,
By providing them continuously at regular intervals, they can be shared.

[0008] Further, on the outside of the frame body, that is, on the side with which the spacer main body is engaged, there is a locking end that engages with the locking end of the spacer main body. In the present invention, the shape of these locking ends is not specified as long as the frame body and the spacer body can be integrated, and when the spacer body is a string-shaped spacer, the space is not limited.
Since the adhesiveness of the server itself can be used, a locking end such as a metal spacer body is not required. Furthermore, these locking ends also serve as a means for aligning the spacer body when the spacer body is engaged with the frame.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view taken along the line AA of the double-glazed glass with the lattice 3 shown in FIG. In the figures, reference numerals 1 and 2 denote glass plates constituting a double-glazed glass;
Is a lattice inserted into the inside of the double-glazed glass, 5 is an aluminum frame for attaching and fixing the lattice 3, and 6 is a string-like spacer body made of Thiokol. Reference numeral 11 denotes a secondary sealing material for further improving the sealing degree of the spacer portion.

As shown in FIG. 3, the frame 5 is provided with ventilation holes 7 at its main part continuously at a constant interval or at an appropriate interval. Is provided. The ventilation holes 7 are for absorbing the desiccant in the spacer body, but can also be used as screw holes for attaching the lattice 3 as described later.

On the other hand, the spacer body 6 is a cord-like body made of thiochol and having a rectangular cross section, into which a desiccant is mixed, and an end on the side engaging with the frame 5 is provided with a frame body. A locking end 13 corresponding to the locking end 12 is formed. The frame 5 and the spacer body 6 can be integrated by fitting the locking ends 12 and 13. When attaching and fixing the grid 3, first, the frame 5
Is fixed to the end of the lattice 3 by screws 8 using the holes 7, and then a spacer body 6 is attached to the outside of the frame 5 to integrate them. In this case, just by pressing the spacer body 6 against the frame body 5, the alignment is simultaneously performed by the locking ends 12 and 13 of the two, and the spacer body is firmly connected due to the adhesiveness of the spacer body. Thus, according to the present invention, it is possible to assemble the multi-layer glass with the frame 3 and the spacer body 6, that is, the spacer attached to the grid 3.

FIG. 4 shows an embodiment in which the spacer body 9 is made of aluminum. The inside of the tubular body is filled with a desiccant 10, and the frame body is passed through a ventilation hole (omitted) provided in the tubular body. 5
Communicates with the ventilation hole 7. The attachment to the grid 3 and the assembly of the double glazing are substantially the same as for the string spacers described above.

Although not shown, the grid 3
May be attached by means other than screws, or the grid 3
In order to facilitate the adjustment of the fixing position, the ventilation hole of the frame 5 may be elongated, so that the position of the grid 3 can be adjusted within the range of this hole.

[0014]

According to the present invention, since the frame 5 can be attached to a decorative member such as a grid while being separated from the spacer main body, the work can be efficiently performed, and at the same time, the spacer main body can be attached to the frame main body in advance. Since the multi-layer glass is assembled after being integrally attached to the glass plate, the multi-layer glass can be formed simply by inserting a lattice with spacers between the glass plates and pressing from both sides. Further, since the spacer body and the frame body are integrated, no gap is formed between them. Furthermore, by previously attaching the spacer body to the periphery of the frame body using the locking means, the positional alignment between the frame body and the spacer body can be made extremely accurate and easy.
