Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-glazed glass with a ventilation function, and more specifically, a double-glazed glass itself is provided with a ventilation function to ensure breathability, thereby structurally opening and closing like a skylight. The present invention relates to a double-layered glass with a ventilation function that can ventilate even a window that cannot be opened or a sliding window that is closed when raining or going out.

[0002]

2. Description of the Related Art Since double glazing is excellent in heat insulation and soundproofing, it has become widely used not only as a window glass for high-rise buildings but also as a window glass for general buildings for consumer use. ing.

In this case, the above-mentioned double glazing is used as a window glass having various structures such as a snap-in window and a sliding window by mounting it on a frame material such as a sash.

On the other hand, in any building, the indoor space needs to be constantly ventilated, but in the case of using the snap-in window, it cannot be structurally opened and closed. Since it is necessary to keep it closed when it rains or when going out, it is the actual situation that ventilation cannot be done through these windows.

For this reason, in order to make it possible to ventilate even through a dead-end window or a sliding window which is in a closed state, a ventilation window in which a ventilation unit is incorporated in a part of a frame material for partitioning a window surface using double glazing Has also been adopted.

FIG. 5 shows an example of a conventional structure of a ventilation window incorporating the above ventilation unit. The entire structure is composed of vertical frames 1a, 1a, an upper frame 1b and a lower frame 1c located on the left and right. A frame member 1 such as a sash frame having an enclosure shape and attached to an opening of a building, and a horizontal rail 2 spanning the frame member 1.
The ventilation unit 5 mounted on the upper opening surface 3 defined by the above, and the window portion 10 made of plate glass mounted on the lower opening surface 4.

Among them, the ventilation unit 5 has a supporting and fixing portion 6 with a through hole 6a held through an upper frame 1b and a horizontal rail 2 as shown in FIG. 6, and a chamber in the supporting and fixing portion 6. It is composed of a fixed plate portion 7 installed in the inner opening and a movable plate portion 8 which can move laterally.

In this case, the fixed plate portion 7 and the movable plate portion 8 are
The movable plate portion 8 is located on the indoor side so as to be in sliding contact with each other, and the ventilation holes 7a and 8a of the same size are provided at predetermined facing portions.

Therefore, when the ventilation unit 5 is operated to ventilate, the movable plate portion 8 is appropriately moved so that the ventilation hole 8a is face-to-face with the ventilation hole 7a of the fixed plate portion 7. As a result, the vent hole 8a, the vent hole 7a, and the through hole 6
By communicating with a, an air passage 9 is formed between the indoor side and the outdoor side as shown in FIG.

On the other hand, when ventilation is not required, the movable plate portion 8 is moved so that the ventilation hole 8a does not face the ventilation hole 7a of the fixed plate portion 7. It is possible to cancel the communication relationship between 7a and prevent the inflow and outflow of air between the indoor side and the outdoor side.

[0011]

By the way, even with the conventional type ventilation window, it is possible to provide a ventilation function to the dead-fitting window or the sliding window which is closed.

However, the ventilation unit 5 has a window 10
Since it is necessary to install it separately from the existing frame material, when installing it on the already installed kill window or sliding window afterwards, replace the existing frame material with the dedicated frame material 1 with the horizontal rail 2. Window part 1
It is necessary to re-install all of them, and there is an inconvenience that the installation cost rises.

Furthermore, even if the ventilation unit 5 is to be incorporated into a portion where rainwater directly falls, such as a skylight, it is difficult to ensure watertightness, so that it cannot be easily adopted.

In view of the above-mentioned problems, the object of the present invention is to use the existing frame material as it is by providing a ventilation function to the double glazing itself, and by providing it with high watertightness, in addition to the skylight and the go-out. It is to provide a double-glazed glass with a ventilation function that allows ventilation even when the window is closed when it rains or when it rains.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view illustrating an embodiment of the present invention by applying it to a double glazing such as a skylight, which is slightly inclined and arranged in a substantially horizontal direction. ,
FIG. 2 is an explanatory diagram showing an enlarged cross-sectional structure taken along the line AA in FIG.

According to these figures, a mounting hole 41 is formed at a predetermined position on the glass surface of the double glazing unit G so as to penetrate the front and back surfaces of the double glazing unit G, and the mounting hole 4 is formed.
The end face 42 of the double glazing G defining 1 is sealed in the same manner as the structure of the end face (four sides) of a normal double glazing. The ventilation unit 11 is installed in the multi-layer glass G through the mounting hole 41. The ventilation unit 11 includes a watertight outer lid portion 12 that covers the outer opening surface 41a of the mounting hole 41.
And an inner lid portion 22 arranged to cover the inner opening surface 41b of the mounting hole 41. In addition,
As shown in FIG. 1, the mounting hole 41 has a double-layered glass G.
Can be formed as a circular hole having a desired diameter on the glass surface at an arbitrary position in FIG. 3, or can be formed in an appropriate shape such as an oval hole as shown in FIG. And its end face 42 is
High water-tightness is provided by interposing a spacer 43 accommodating a hygroscopic agent and then filling and sealing with a sealing material 44 as in the case of an end face structure in a normal double glazing.

In this case, the outer lid portion 12 which constitutes the ventilation unit 11 can be ventilated without allowing the inflow of water liquid and covers the outer opening surface 41a, and this cover portion 13. The end face 4 is supported by the mounting hole 41.
It is integrally formed with a supporting hem portion 21 that is fixed to cover the two.

Of these, the cover portion 13 is provided with a peripheral wall portion 14 standingly arranged on a glass surface peripheral portion 45 which defines an outer opening surface 41a of the mounting hole 41, and the peripheral wall portion 14 of the peripheral wall portion 14. At least a top plate portion 15 that covers the upper surface is provided, and a through hole 14a is formed in an appropriate portion of the peripheral wall portion 14 located on the downstream side in the flow direction of the water liquid.

In addition, the peripheral wall portion 14 located at the portion where the through hole 14a is formed prevents inflow of water liquid into the mounting hole 41 through the through hole 14a. The layer 16 is formed. Specifically, FIG.
As shown in FIG. 3, the partition wall portion 17 having the through hole 17a is arranged inside the peripheral wall portion 14 to form the space portion 18 between them, and the water liquid flows into the space portion 18 while having the air permeability. The inflow blocking layer 16 is formed by filling an appropriate inflow blocking material such as a sponge material or a glass wool material that does not permit the above, or by forming a labyrinth structure between the peripheral wall portion 14 and the partition wall portion 17. In this case, it is desirable that the through hole 17a of the partition wall portion 17 be disposed slightly above the through hole 14a of the peripheral wall portion 14 from the viewpoint of more reliably blocking the inflow of water liquid. Further, although the inflow prevention of the water liquid can be achieved only by providing the through holes 17a and the like at desired positions without forming the above-mentioned appropriate inflow prevention layer, in order to obtain a higher inflow prevention property, It is desirable to have a suitable inflow blocking layer.

Further, the supporting hem portion 21 integrally formed with the cover portion 13 is fitted into the mounting hole 41 and supported on the side of the double glazing G while covering the end face 42. , And has a sitting height that matches the overall thickness of the double-glazing unit G. The cover 1
3 is provided with a compartment 19 on the side facing the glass surface peripheral edge portion 45 of the peripheral wall portion 14 and is integrally formed with the supporting hem portion 21, and an appropriate waterproof material 20 is arranged in the compartment 19 to form a composite. For example, to secure water tightness between the glass layer G and the peripheral edge portion 45 of the glass surface.
And is provided with appropriate waterproofing treatment.

On the other hand, the inner lid portion 25 is arranged so as to be freely attached to the supporting hem portion 22 and is provided with the inner opening surface 41b.
And a ventilation control plate portion 30 that movably holds the base portion 26 to control the ventilation between the base portion 26 and the base portion 26.

Of these, the base portion 26 is supported by and covers the glass surface peripheral edge portion 46 defining the inner opening surface 41b, and at a suitable facing portion with the inner opening surface 41b. An abutment support portion 27 having a through hole 27a, and a mounting portion 27 that is erected from the abutment support portion 27 to the supporting hem portion 22 so as to be freely attached to each other are integrally formed.
The mounting portion 28 and the supporting hem portion 22 can be fixed to each other in an appropriate structure, for example, a female screw portion 21a is provided on the inner peripheral surface of the supporting skirt portion 21 as shown in the illustrated example. ,
A screwing structure in which a male screw portion 28a is provided on the outer peripheral surface of the mounting portion 28, an appropriate fitting structure between the mounting hem portion 21 and the supporting hem portion 21 is adopted, or a mechanical joining structure is used. It is formed by adopting it.

The ventilation control plate portion 30 is movably held by the base portion 26 and is arranged to control the ventilation between the base portion 26. Is
It is movably supported by holding its peripheral portion in a support groove 28a defined by a supporting arm portion 28 extending vertically from the contact support portion 27 side.

Moreover, the ventilation control plate portion 30 has a through hole 27a provided in the contact support portion 27 according to the movement state thereof.
And the through holes 30a are arranged in such a manner that they can be brought into a complete facing state, a partial facing state, or a non-facing state.

When the ventilation control plate portion 30 is formed in a circular shape as shown in FIG. 2, by rotating the ventilation control plate portion 30, the through hole 30a is made to pass through the through hole 27a of the contact support portion 27. And the face-to-face relationship as described above.

On the other hand, FIG. 3 shows an example in which the ventilation unit 11 is arranged on the multi-layer glass G arranged vertically, and in this case, the ventilation unit 11 having the same circular shape as in FIG. Besides, one or more ventilation units 1 having an appropriate shape, such as a ventilation unit 11 having an oval shape.
1 are arranged under the same arrangement relationship as the structure shown in FIG. When the ventilation unit 11 having an oval shape or other non-circular shape as shown in FIG. 3 is provided, the ventilation control plate portion 30 is also formed in a shape corresponding to this. Therefore, by moving the through holes 27a and 30a in the appropriate directions according to their shapes, the relationships of complete facing, partial facing, and non-facing between the through holes 27a and 30a can be obtained.

Further, the ventilation unit 1 according to the present invention.
1 is, for example, as shown in FIG. 4, an outer lid portion 12 and an inner lid portion 25.
It may include an electric fan F, which is driven and controlled by, for example, a solar cell or another power source, which is built in an internal space defined by and.

The outer lid portion 12 and the inner lid portion 16 constituting the ventilation unit 11 are made of a non-ferrous metal material such as stainless steel or a synthetic resin such as vinyl chloride resin in consideration of corrosion resistance and strength. It is preferably formed by using a material.

Further, in the illustrated example, by fitting the supporting hem portion 21 into the mounting hole 41 of the double glazing unit G, the outer lid portion 12 is provided on the side of the double glazing unit G while covering the end face 42. Although the case where it is supported is shown, the arrangement relationship with the inner lid portion 25 may be reversed. That is, the mounting portion 29 of the inner lid portion 25 is fitted into the mounting hole 41 of the double glazing unit G so that the inner lid portion 25 is first supported on the side of the double glazing unit G while covering the end surface 42. The ventilation unit 11 may be installed by screwing a male screw portion provided on the supporting hem portion 21 of the outer lid portion 12 into a female screw portion provided on the portion 29.

Since the present invention is constructed in this way, the ventilation unit 11 composed of the outer lid portion 12 and the inner lid portion 25 is made of the double glazing G as shown in FIG. 1 and FIG. It can be installed in a highly watertight structure through the mounting holes 41 provided at arbitrary positions. That is, the ventilation unit 11 is installed on the double glazing G itself which is used as a window glass such as a fitting window, a sliding window or a skylight, so that the existing frame member holding the double glazing G is installed. Since it can be used as it is, it can contribute to the reduction of the installation cost.

In addition, the ventilation unit 11 is made of double-layer glass G
The outer lid portion 12 can be arranged by introducing the supporting hem portion 21 from the side of the outer opening surface 41a into the mounting hole 41 so as to cover the end surface 42 thereof. At this time, by filling and mounting the waterproof material 20 in the compartment 19, it is possible to secure the watertightness with the multilayer glass G.

After the outer lid portion 12 is provided, the mounting portion 29 is fed into the mounting hole 41 while the inner opening surface 41b is covered with the contact supporting portion 27, and is screwed to the supporting hem portion 21. The inner lid portion 25 is arranged by fastening it by fitting or fitting, and the ventilation unit 11 is formed as a whole. As described above, the supporting hem 2
When the positional relationship between 1 and the attachment portion 29 is opposite to the illustrated example, the outer lid portion 12 side is attached to the inner lid portion 25 side.

In this case, the through hole 1 provided on the outer lid 12 side
4a communicates with the mounting hole 41 through the inflow prevention layer 16, and moreover, since the through hole 14a is located on the downstream side in the flow direction of the water liquid, the water liquid is mounted for mounting. The ventilation state can be always ensured while surely preventing the intrusion into the hole 41.

On the other hand, on the side of the inner lid portion 25, the ventilation control plate portion 3
0 is moved to bring the through hole 30a into contact with the contact support portion 27.
The ventilation control can be easily performed by increasing / decreasing the ventilation amount or by setting the ventilation hole 27a in a completely facing state, a partial facing state, or a non-facing state.

Therefore, it is preferable not only for a skylight that has a slight inclination and is placed in a substantially horizontal state (see, for example, FIG. 1), but also for a fit-and-kill window and a closed sliding window (see, for example, FIG. 3). Ventilation function can be added.

Further, as shown in FIG. 4, when the ventilation unit 11 has an electric fan F built therein, a forced ventilation function can be provided, and a more preferable ventilation state can be obtained.

[0038]

As described above, according to the present invention, since the ventilation unit including the outer lid portion and the inner lid portion is installed in the double glazing itself, the existing unit for holding the double glazing is used. A frame material such as a sash frame can be used as it is, which can contribute to a reduction in installation cost.

Moreover, since the ventilation control can be arbitrarily performed by moving the ventilation control plate, it has a watertight structure which is excellent not only for the skylight and the dead-end window but also for the sliding window that is closed. An originally preferable ventilation function can be provided.
