[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a glass body and an attachment for a glass plate, and more specifically, a glass plate such as multi-layer glass and laminated glass having different standard sizes, and glass that can be used flexibly for various types of sashes. The present invention relates to a plate attachment and a glass body on which the plate attachment is mounted.
[0002]
[Prior art]
Multi-layer glass formed by separating two or more glass sheets through a spacer containing a hygroscopic material and sealing the four circumferences of the glass is insulative, soundproof, dewproof, etc. In addition to exhibiting excellent effects, additional functions such as solar shading and safety can be added, so it fits well with today's needs where energy saving and safety are important, and it can also be used for buildings and general homes. Large demand is expected. By the way, this type of double-glazed glass has a thickness of nearly three times that of a single-plate construction consisting of a single sheet of glass, so it can be mounted on a standard sash for single-plates. Even if it is going to do, it does not fit in the glass groove for plate glass material attachment on the sash side, and the direct attachment of the double glazing to the sash side is practically impossible.
[0003]
For this reason, a sash dedicated to multi-layer glass is prepared in advance, or when attaching multi-layer glass to the above-mentioned type of sash, an insertion support leg that can be attached to the glass groove of the sash And a multi-layer glass attachment comprising a holding frame portion that holds the peripheral edge of the multi-layer glass so as to sandwich the multi-layer glass, and the multi-layer glass is attached to the sash side through this attachment. ing.
[0004]
In recent years, laminated glass, which is expected to increase in demand in the future due to heightened awareness of crime prevention, has a thickness width at least twice that of a single-plate glass plate. The same problem as in the case of.
[0005]
A supporting leg formed on the attachment main body by fitting the peripheral edge of the double-glazed glass to the metal attachment main body via a resin cushioning member, which has been proposed as a conventional double-glazed glass attachment. There exists what comprised the part so that a part might be supported by a sash (for example, patent document 1).
[0006]
However, since this multi-layer glass attachment is attached simply by engaging the buffer member with the attachment main body, a gap is generated between the buffer member and the attachment main body when the buffer member is thermally contracted. In some cases, the service life may be hindered.
[0007]
Therefore, in order to prevent the thermal shrinkage, the following multilayer glass attachment in which a buffer member and an attachment body are integrally formed has been proposed.
[0008]
FIG. 9 is a cross-sectional view showing the structure of a conventional multi-layer glass attachment, and FIG. 10 shows the relationship between members when the multi-layer glass is attached to the sash side using the attachment. It is explanatory drawing illustrated. In each figure, (a) is a configuration for a sliding window, and (b) is a configuration for a fitting window.
[0009]
According to the figure, the multilayer glass attachment 1 includes an attachment main body having a holding frame portion 2 and an insertion support leg portion 4 and a buffer member 3 integrally attached to the inside of the holding frame portion 2. Further, in the case of a sliding window (the configuration shown in FIG. 5A), a bead material 5 that is integrally attached to the insertion support leg 4 side is added.
[0010]
In FIG. 10A, the double-glazed glass attachment 1 to which the double-glazed glass G is attached has the insertion support leg portion 4 to which the bead material 5 is attached fitted and fixed to the glass groove of the sash 50. .
[0011]
In FIG. 10 (b), the double-glazed glass attachment 1 to which the double-glazed glass G is mounted is inserted with the insertion support leg 4 placed on the setting block 56 in the glass groove of the sash 50. The supporting leg portion 4 is sandwiched and fixed between beads on both sides (a front bead 52 and a rear bead 54). A pressing edge 50 </ b> A is attached to the outside of the retrofitted bead 54.
[0012]
As described above, the holding frame portion 2 and the buffer member 3 of the multilayer glass attachment 1 are generally formed integrally. By integrally forming in this way, the holding frame portion 2 and the buffer member 3 are bonded to each other, and a gap is not easily generated between the holding frame portion 2 and the buffer member 3. As a result, the peripheral edge of the multilayer glass G is protected against the intrusion of rainwater or the like.

[0014]
[Problems to be solved by the invention]
However, the multilayer glass attachment 1 having the above-described conventional configuration has a problem in terms of recycling. That is, in many examples of the multilayer glass attachment 1, an aluminum material is used as the holding frame portion 2 and a resin material is used as the buffer member 3.
[0015]
In this case, it is necessary to separate and collect at the time of recycling, but it is very difficult to separate and recover the aluminum material and the resin material because the multilayer glass attachment 1 is integrally formed. In addition, when this is done, a large cost is required.
[0016]
Moreover, there is a fact that it is not necessarily economical that the multilayer glass attachment 1 is integrally formed. That is, the attachment 1 is integrally formed by extruding aluminum and inserting the aluminum material into a resin mold to perform resin molding. However, the molding time of resin molding is about 1/10 of the molding time of aluminum, and as a result, the molding time of the attachment 1 is delayed.
[0017]
The present invention has been made in view of such circumstances, can be easily separated and collected at the time of recycling, is reliable in long-term use, and has a high productivity for a glass plate attachment and It aims at providing the glass body which mounted | wore with this.

There are a variety of fixing methods for aluminum and resin, but in this example, a typical fixing method was proposed. When the resin insertion portion 14 is separated as shown in FIGS. 1 and 2, the temperature of the outside air during outdoor use is different due to the difference in coefficient of linear expansion between the aluminum main body portion 12 and the resin insertion portion 14. Thus, the temperature rise and cooling are repeated, and each member repeats expansion and contraction. Due to the difference in linear expansion coefficient, the insertion portion 14 that has been subjected to repeated cooling and heating contracts more than the main body portion 12, and the main body portion 12 and the insertion portion 14 are not fixed at both ends in the length direction, as shown in FIG. A gap will be generated at the corner of the multilayer glass body. The attachment 10 for double-glazed glass generally has a corner portion cut by 45 degrees and screwed, but when an insertion portion 14 in which a tapping hole 14n is not formed as shown in FIG. 23 is used. , Will become a gap at the corner, and lose the waterproof effect. As a countermeasure against this, adhesion or mechanical coupling in the longitudinal direction of the main body 12 and the insertion portion 14 can be considered. Since recyclability is inferior when bonded or mechanically fixed in the longitudinal direction, a fixing method such as a caulking method in which both ends are mechanically fixed is preferable. With the caulking method, the main body portion 12 made of a metal member and the insertion portion 14 made of a resin member can be easily separated at the time of recycling.

【The invention's effect】
As described above, according to the present invention, a glass plate attachment is configured by combining a main body portion made of a metal member and an insertion portion made of a resin member formed separately from the main body portion. Since the main body portion and the insertion portion are fixed at both ends in the length direction, even if the insertion portion is thermally contracted in the length direction, a gap is hardly generated at both ends in the length direction. As a result, there is no gap for moisture to enter, and the reliability is high in long-term use. In addition, when recycling, the main body made of a metal member and the insertion portion made of a resin member are configured separately, so there is an advantage that they can be easily separated and collected. Productivity is good because the part is molded separately.
