Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a double-glazed glass unit with an adapter.

Double-glazed glass, which is made by joining a pair of glass plates separated by a spacer containing a desiccant agent around the edge, is rapidly becoming in demand in general households due to its excellent heat and sound insulation performance. It is increasing.

However, since double-glazed glass is nearly three times as thick as a single glass plate, it cannot fit into the glass plate mounting groove of a normal sash. Therefore, as a solution to the above problem, a double glazing unit with an adapter has appeared, which is constructed by fitting an adapter provided with a protruding flange that can fit into the glass plate mounting groove of a normal sash onto the periphery of the double glazing glass. There are two ways to seal between the adapter and the edge of the double-glazed glass in this type of double-glazed glass unit: one is completely filled with a curable amorphous sealant, and the other is a method that uses pre-formed elastic beads. Although this method has the advantage of being faster to assemble than the former method, it also poses the following problems during use.

In other words, as a result of the edge of the double-glazed glass coming into contact with rainwater that has entered through the micro-gaps that exist between the bead and the glass surface for a long period of time, moisture penetrates into the interior through the adhesive layer of the double-glazed glass, and the desiccant absorbs moisture. There was a problem that the performance deteriorated early.

The purpose of the present invention is to solve the above-mentioned problems in a double glazing unit with an adapter using elastic beads.

That is, the present invention is a multi-layer structure with an adapter, which has a flange for attaching to the sash and is fitted onto the periphery of a pair of glass plates separated by a spacer at the ends via an elastic bead. In the glass unit, a drainage hole is provided in the bottom wall of the elastic bead at the lower side of the unit, and a groove is provided in the bottom wall of the adapter at a position lower than the bottom surface of the bottom wall, and connected to the groove to drain water. A hole is provided through the flange. The gist of this is that

The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 shows a sectional view of essential parts of a double-glazed glass unit with an adapter according to the present invention, and FIG. 2 shows a front view of the unit.

As shown in the figure, the unit 1 is made by wrapping an elastic bead 5 around the entire periphery of a double-glazed glass 4, which is made by bonding and integrating a pair of glass plates G with a spacer 3 containing a desiccant 2 at the end. Further, a metal adapter 6 is fitted over the entire periphery of the double-glazed glass 4 via the elastic bead 5.

A double-glazed glass fitting groove 7 is formed in the adapter 6 with side walls 6A and 6B and a bottom wall 6C.
A flange 8 for attaching the unit 1 to the glass fitting groove 12A of No. 2 is integrally formed. In addition, by locking the side end locking portions of the elastic bead 5 to the tips of both side walls 6A and 6B of the adapter 6, a certain amount of space is provided between the edge of the double-glazed glass 4 and the bottom of the fitting groove 7. There is.

Double-glazed glass unit with adapter of the above structure 1
Between the bead 5 and the surface of the double-glazed glass 4,
The following measures have been taken to quickly discharge rainwater that enters through the microscopic gap between the adapter 6 and the bead 5 to the outside.

That is, a drain hole 5A is provided in the bottom wall of the double-glazed glass unit with adapter, which is in contact with the edge of the double-glazed glass of the elastic bead 5 at the lower side.

In addition, the bottom wall 6C of the glass fitting groove 7 of the adapter 6, which forms the bottom of the unit 1 in the installed state, is designed to prevent water that collects in the groove 7 from being removed.
In order to discharge the gas into the glass plate fitting groove 12A of No. 2, a concave groove 9 is formed at a position lower than the bottom surface of the bottom wall 6C.
Drain holes 10, 10 are provided continuously in the longitudinal direction of the bottom wall, and are connected to the grooves and located near both corners of the lower side of the unit 1. A drainage hole is provided to penetrate the flange 8 and drain water to the sash 12. To attach the unit 1 to a normal sash, as shown by the imaginary lines in FIG. and insert it.

According to the above structure, rainwater that enters between the elastic bead 5 and the surface of the glass G passes through the drain hole 5A of the bead 5 and falls into the glass fitting groove 7 of the adapter 6, where the adapter 6 and the bead 5 It is collected in the water collection groove 9 along with the rainwater that enters from between the drain hole 10 and drained into the sash 12 through the drainage hole 10.

And since a normal sash is already equipped with a drain, rainwater is drained outside through this existing drain.

According to the present invention, double-glazed glass can be attached to ordinary sashes, and the edges of the double-glazed glass are always kept dry, preventing deterioration of the adhesive layer or desiccant of the double-glazed glass due to the presence of moisture. Stable performance is maintained over a long period of time. Since double-glazed glass is much thicker than normal single-pane glass, rainwater that enters the glass fitting groove of the adapter frame stagnates in the wide area of the glass fitting groove due to surface tension. However, there is a problem that it is difficult for the water to flow into the drain hole.
In the present invention, a narrow groove one step lower is provided in the glass fitting groove, so rainwater is collected in this groove and can be efficiently drained from the drain hole.

In addition, since the groove 9 is provided at the position of the flange 8, the thickness of the bottom wall 6C of the glass fitting groove at the base of the flange 8 is relatively thin due to the presence of this groove. Due to the bending moment applied inward to the side walls 6A and 6B of the adapter due to its own weight, these side walls and the bottom wall portion following them are elastically deformed toward the glass plate, and the bead 5 is pressed against the glass plate surface, making it even more watertight. Sexuality increases.

Further, the collection of stagnant rainwater into the groove 9 due to the bending deformation of the bottom wall portion is promoted.
