Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a double glazing device.

[Conventional technology]

Conventionally, this type of double-glazed window device has been constructed by directly attaching two glass plates, plastic plates, etc. to the window frame, or as described in Japanese Utility Model Application No. 51-47537 and Japanese Patent Application Publication No. 57-190891. As shown in the figure, it was common to have a structure in which similar glass plates were placed on the surface of a glass window at regular intervals, and the periphery of both was firmly attached using a magnetic device or the like.

[Problem that the invention attempts to solve]

However, with this type of structure, if the sealed air inside the double-glazed window is abnormally heated and expands due to the outside temperature or indoor temperature, the pressure will cause the inside to
There were problems such as the possibility of accidents such as damage to the outer glass panel.

[Means for solving problems]

The present invention has an inner adsorption part and an outer adsorption part made of magnetic metal or magnets, which are installed opposite to each other on the inside and outside parts of the window frame, and the inner adsorption part and the outside adsorption part, respectively, are attached to the periphery by suction. The inside of the above window frame is kept airtight, and the above suction part is slightly opened by the expansion pressure of the air sealed inside the window frame, and a moment after a part of the same high pressure air is discharged, it is immediately adsorbed. An attempt is made to solve these problems by providing a double-glazing device characterized by comprising an inner window and an outer window each having an attracted part made of a magnet or magnetic metal that returns to its original state. It is something.

〔Example〕

In the embodiment shown in the figure, an L-shaped sash 2 made of magnetic metal is fixed with screws to the inner peripheral surface of a window frame 1 with a decorative edge 1' that fits into a window hole (not shown) provided in the wall of a house. The inner suction part 3 and the fitting space 4 of the inner window 26, which will be described later, are formed, and a narrow magnetic metal plate 5 is fixed to the outer surface of the window frame 1 by adhesive via a sponge cushion 6 to form the outer side, which will be described later. A C-shaped groove in a long plastic sash 11 that forms the outer suction part 7 of the window 27 and has a cross-sectional shape that is a combination of a narrow U-shaped groove 10 on the back side of a C-shaped groove 9. By fitting the rubber magnet strip 12 containing magnet powder into the magnet strip 9 in such a manner that the opening edges 13, 13' of the C-shaped groove 9 bite into both side edge surfaces of the magnet strip 12 and cannot be removed. First glass frame material 14
This first glass frame material 14 is cut into appropriate lengths, and a plurality of the shredded bodies 15 are joined together in an inverted U shape to form an edge frame 16.
6, the outer peripheral edge of the glass plate 17 is inserted into the narrow U-shaped groove 10, and the glass plate 17 is inserted into the edge frame 16.
At the same time, separately from these, a wide inverted U-shaped groove 20 is integrated with the lower surface of the narrow U-shaped groove 19, and a finger hook 21 is provided which extends in a shape from the upper side of the narrow U-shaped groove 19. Wide inverted U-shaped groove 20 in a long plastic sash 22 with a protruding cross-sectional shape
A second glass frame material 24 is constructed by pasting and fitting a rod-shaped sponge 23 inside with an adhesive, and the second glass frame material 24 is cut into pieces to form a narrow U-shaped groove of the shredded body 25. 19 to the above glass plate 1
7 to form an inner window 26 and an outer window 27, and by fitting the inner window 26 into the fitting space 4, the magnetic strip 1 is attached to the inner adsorption part 3.
Similarly, the outer window 27 is attracted to the outer attraction portion 7 by the magnetic band plate 12.

[Functions and effects of the invention]

Since the present invention is as described above, the air sealed between the inner and outer windows is on the verge of expanding to the point where the above-mentioned windows become abnormally high due to outside and indoor temperatures and are damaged. It is possible to prevent the above-mentioned damage to the window by slightly opening the gap between the window and its suction part, and discharging a part of the expanded air from the same part. After a moment when the above-mentioned part of the air is discharged, the suction function of the suction part is activated and the suction part can immediately return to the suction state. This has the effect of being able to sufficiently solve the above-mentioned problems without any loss. .
