Description

  The present invention relates to an outer window / inner window structure having a blind function. More specifically, the present invention relates to an outer window / inner window structure which can use a conventional window glass as it is, has a simple construction, has a daylighting and blocking function (blind function), and is excellent in a heat insulating effect and a soundproofing effect.

  Recently, as one of the energy-saving and soundproofing measures for buildings, especially houses, the use of double-glazed windows has become widespread. The double-glazed glass currently on the market forms a space of a certain distance between two glass plates, and the space is sealed with a sealant, and the sealed space is kept dry by enclosing the desiccant. It is configured. In order to enhance the energy saving effect of this multilayer glass, it has also been proposed to bond a transparent heat insulating film to a glass plate.

  The normal multilayer glass has a space (interval between two glass plates) of about 6 mm, and the thickness of one glass plate is about 3 mm, so that the total thickness is at least 12 mm.

  On the other hand, in the case of a sash window made of single layer glass, the thickness of the glass plate for a general house is 8 to 9 mm. If it is to be installed, it will be necessary to replace the entire sash frame, so the renovation costs will be substantial. Moreover, even if it is a new construction or a renovation, if the above-mentioned double glazing is installed, the goal of blocking / insulating and soundproofing will be achieved.

  In contrast, as a result of research on the structure and material of a spacer that can reduce the space between two glass plates and that can enclose and hold a desiccant, the present inventor has developed a metal having a specific cross-sectional shape. It has been found that by using a spacer made of (aluminum, stainless steel, etc.) or resin, the desiccant can be easily enclosed in the spacer, and the distance between the glass plates can be made about 2 mm. This multilayer glass can be made into two glass plates with a thickness of 3 mm and a space with a spacing of 2 mm, so that it is possible to achieve about 8 mm as a whole. This multi-layer glass having a thickness of about 8 mm can be inserted as it is into the window frame of a conventional sash window of single-layer glass, and its utility value is enormous and has already been put into practical use. This multilayer glass is proposed as Patent Document 1.

The proposed double-glazed glass (hereinafter referred to as “thin double-glazed glass”) has a high practical value in that a conventional sash window frame of a single-layer glass can be used as it is, and is thin. It is also used as an energy-saving window for showcases.
In view of this, the present inventor has focused on the combined use with a conventional single-layer window glass in order to further expand the use of the thin-type multi-layer glass, as well as its heat-shielding / heat-insulating and sound-proofing effects and being thin and lightweight. It was. That is, the thin multi-layer glass was superposed on the already installed single-layer glass window, and the effect was examined. As a result, the effect of preventing dew condensation is insufficient, and interference fringes are generated on the glass surface, which cannot be put into practical use as they are. Furthermore, what was superimposed or pasted as it was did not have an aesthetic appearance.

  The present inventor, when laminating the thin multi-layer glass to the window glass, condensation does not occur, interference fringes are not observed, the construction is simple, and also the aesthetic appearance is further laminated. Research was conducted on a structure with no problem in adhesive strength and safety.

As a result, the window glass structure satisfying the following items (i) to (v) sufficiently prevents the occurrence of condensation, has no interference fringes, is excellent in design, and is easy to install. Was also found to be firmly bonded and safe. Furthermore, it has been found that the existence of a space at a constant interval between the thin multi-layer glass and the window glass further improves the heat insulation / heat insulation effect and increases the sound insulation effect.
(I) The distance between the two glass plates facing the thin multi-layer glass and the window glass is kept constant.
Holding
(Ii) Thin multi-layer glass is fixed around the periphery with a channel having an L-shaped cross section.
The end of the tunnel is not in contact with the window glass and is separated at regular intervals.
(Iii) The thin multi-layer glass has a small solid piece between the bottom surface and the installation surface.
It is installed at intervals, and the space with the installation surface is filled with sealing agent,
(Iv) The thin multilayer glass has a thin multilayer glass space on the surface to be bonded to the window glass.
Opaque film is adhered around so that the sealer and sealant cover it
That
(V) The thin multi-layer glass is a contact portion with the window glass on both side surfaces and the upper side surface.
Is covered with sealant.

  Based on the above investigation facts, the present invention has proposed, as Patent Document 2, a window glass structure for preventing condensation, in which the thin multi-layer glass is bonded to the inner or outer glass surface of the window glass.

  The proposed window glass structure is a structure having an outer window / inner window structure, and has excellent functions for preventing condensation, heat insulation, and sound insulation.

Therefore, in order to further expand the use of the thin multi-layer glass, the present inventor noticed that it is thin and lightweight as well as its shielding / insulating effect and soundproofing effect, and already installed single-layer glass window or multi-layer glass. Research on the combination with windows was advanced.
In particular, research was conducted on the blind function, that is, the function of transmitting and blocking light. As a result, taking advantage of the thin multilayer glass, taking advantage of its thinness and light weight, by installing a polarizing film on one glass surface of the multilayer glass space so that light is polarized in a specific direction, blinds It has been found that it exhibits a function (it can arbitrarily control the transmission and shading of light) and has reached the present invention.

The top view (FIG. 1-a) which looked at the outer window and inner window structure of this invention from the room inner side is shown. 1-b shows a cross-sectional view taken along the line XX ′ of FIG. 1-a, and FIG. 1-c shows a cross-sectional view taken along the line Y-Y ′ of FIG. Sectional drawing of the window frame and multilayer glass which are used for the inner window part in the outer window and inner window structure of this invention is shown. The top view seen from the room inner side which showed the arrangement | positioning state of the polarizing film with which the glass surface of the outer window part and inner window part in the outer window and inner window structure of this invention was mounted | worn is shown. FIG. 3A shows the glass surface of the outer window portion, and FIG. 3-B shows the glass surface of the inner window portion.

The outer window / inner window structure having a blind function of the present invention is roughly divided into the structure [I] (hereinafter may be abbreviated as “structure-I”) and the structure [II] (hereinafter referred to as “structure”). 2 types of structures (which may be abbreviated as “Structure-II”). Structure-I and Structure-II are both composed of an outer window portion and an inner window portion, and the inner window portion is common in that it is a multilayer glass structure. However, the structure-I is a sliding window using a single layer glass for the window of the outer window, and the structure-II is a structure of a multilayer glass for both the outer window and the inner window. It is different.
Hereinafter, the structure of the window frame in the outer window / inner window structure of the present invention will be described with reference to the drawings.

FIG. 1 shows a plan view (FIG. 1-a) viewed from the indoor side when the outer window / inner window structure of the present application is attached to a window portion.
Therefore, FIG. 1A shows the outer frame and the window frame of the inner window portion, and the two window frames are sliding windows. FIG. 1-a shows the window closed.
Since FIG. 1-a is a plan view seen from the room, the outer window portion on the outside thereof is not shown.

  1-b shows a cross-sectional view taken along line XX ′ in FIG. 1-a, and FIG. 1-c shows a cross-sectional view taken along YY ′ in FIG. That is, FIG. 1-b and FIG. 1-c show cross-sectional views of the structure-I of the present invention (the outer window is made of a single layer glass). The structure-I of the present invention is attached to the indoor side of an existing single-layer glass window. In FIG. 1-a, the existing window (hereinafter referred to as "outer window" or "outer window part") is referred to. Is not shown). 1B shows the outer window portion and the structure-I of the present invention attached to the outer window portion. In FIG. 1B, the outer window portion is a sliding window made of the single-layer glass 3. However, the outer window portion may be a fixed window formed of a single single-layer glass. It may be a glass window (Structure-II).

  As shown in FIGS. 1-b and 1-c, the structure-I of the present invention has an outer frame in which two window frames 1 have grooves having a concave cross section at the top and bottom (and in some cases left and right as well). Is held by the outer frame 4 so as to be openable and closable. On the upper and lower sides of the outer frame 4, grooves having two concave cross sections are formed.

In the outer window / inner window structure of the present invention, the outer frame and the outer frame of the inner window part and the window frame may all be made of aluminum sash, plastic and wood, but the outer window part is generally An aluminum sash is preferable, and the inner window portion may be plastic or wooden.
In the structure-I of the present invention, the single layer glass used for the outer window may be a conventional single layer glass, and the thickness is usually 7 to 15 mm, preferably 8 to 14 mm.

Next, the structure of the double glazing of the inner window portion used in the structures-I and II of the present invention will be described with reference to FIG. Further, the double-glazed glass of the outer window used in the structure-II has basically the same structure as the double-glazed glass of the inner window.
As this multilayer glass, those described in JP-A-8-169733 and JP-A-2009-24415 are preferably used.

  The two window frames used for the inner windows of the structures-I and II of the present invention are fixed by four frames on four sides so as to surround the periphery of the multilayer glass. A cross-sectional view thereof is shown in FIG. This sectional view corresponds to the sectional view of the inner window portion of FIG. 1-c in FIG. In FIG. 2, the upper and lower frame portions are particularly enlarged to illustrate the structure of the multi-layer glass. In FIG. 2, the multilayer glass 2 is enclosed in the upper and lower frames 21. The frame 21 has a concave recess so that the end of the multilayer glass 2 is inserted.

  The multilayer glass 2 is formed of two glass plates 22, a spacer 24 for holding a space between the two glass plates, a desiccant contained in the spacer 24, and a sealing agent 23. In FIG. 2, the desiccant accommodated in the spacer 24 is omitted in the drawing.

The multilayer glass 2 used for the window frame of the present invention preferably has a structure that satisfies the following requirements (i) to (iv).
(I) The spacer is formed from a plate-shaped molded body,
(Ii) When the spacer is installed between the glass plates, at least one of the glass surfaces
Is essentially a line or point contact,
(Iii) The spacer has a shape that can accommodate the desiccant therein, and (iv) the spacer can pass gas through the space between the inside and the two glass plates.
It has a communication path.

  The double-glazed glass satisfying the requirements (i) to (iv) is particularly characterized by the structure of the spacer 24 and the structure in which the spacer 24 is mounted on two glass plates. The layer glass can be made extremely thin, and based on this, the thickness of the window frame can be reduced and the weight can be reduced. The requirements (i) to (iv) of the multilayer glass will be described more specifically.

  When the spacer 24 in the multilayer glass 2 is placed between two glass plates, it is substantially in line contact or point contact with at least one glass surface. A space is formed between the two glass plates 22 by spacers 24. The spacer 24 is in contact with one glass plate 22 with a line, and is in contact with the other glass plate 22 with a surface. The point where the glass plate 22 and the spacer 24 are in contact is the left end portion of the spacer 24 in the drawing.

  The cross-sectional shape of the spacer may be the shape shown in FIG. 2, or may be another cross-sectional shape. The spacer has a closed space formed between two glass plates and a communication path through which gas can flow. For example, in the case of the spacer 24 in FIG. 2, the left spacer end portion is not in contact with the glass plate 22 and is separated by a narrow interval. This interval is sufficient if gas can flow, and should be an interval through which the desiccant particles cannot pass. Further, the communication path may be one in which a small hole is provided in the spacer. As described above, the communication path through which the gas flows needs to have a size that prevents the desiccant particles from passing therethrough.

  In the double-glazed glass, a spacer and a desiccant are disposed between two glass plates as described above, and the internal gas is kept in a dry state by a sealant usually used in the double-glazed glass. The sealant is filled between two glass plates outside the spacer as is commonly used, and is shown as sealant 23 in FIG. As this sealing agent, what is normally used for double-layer glass can be utilized. Typical examples of the sealant include poly (isobutylene), polysulfide, silicone, and polyurethane. These are preferable because they have a low water vapor transmission rate, maintain an adhesive force for a long time, and are excellent in followability in the tensile direction.

  In the multi-layer glass, it is preferable that a transparent surface heating element is mounted on the inner side of the single-sided glass plate, so that condensation can be prevented or suppressed. As a method of mounting the transparent surface heating element on the inner side of the glass plate, means known per se in the multi-layer glass can be used. For example, a film of tin or indium oxide, gold or silver metal or an alloy thereof may be directly formed on the surface of a glass plate by a sputtering method or a sintering method. The method of affixing to a glass plate may be sufficient. When a transparent surface heating element is mounted, electrodes made of silver or gold are attached to both ends of the surface, and in use, a voltage is applied to heat the surface to prevent condensation.

  Moreover, the heat insulation function of a double glazing can be further strengthened by mounting a transparent heat insulating film on the inside of a glass plate on one side of the double glazing. That is, since the double-glazed glass has a thin space portion, it is very effective to attach the transparent heat insulating film to compensate for the lack of the cross-sectional effect. The transparent heat insulating film is commercially available per se and can be used as it is.

  The multilayer glass has a thin overall thickness and itself has a heat insulating effect and a dew condensation preventing effect. For example, by using two pieces of glass having a thickness of 2.7 to 3 mm to form a double layer glass having a space thickness of 2 mm, a thin double layer glass having a total thickness of 7.4 to 8 mm can be obtained.

  The structures-I and II of the present invention have a very thin total thickness, and the protruding feeling when installed is greatly reduced. Moreover, since it is thin and lightweight, it can be easily installed and opened and closed. Even though the sliding window is an excellent effect, the structure of the inner window portion is characterized by being lightweight and thin, and extremely excellent in the effect of shielding / insulating and soundproofing.

  Furthermore, Structure-I and II of this invention can cut the heat ray from external air significantly by sticking a transparent heat insulation film inside the at least one glass plate of the multilayer glass in a window frame. That is, it becomes easy to greatly cut the heat rays from the sunlight in summer. On the other hand, it is possible to prevent the indoor heating from escaping outside in winter. Since the structure of the present invention is a sliding window frame and is easy to mount, changing the inside and outside of the glass surface of the window frame in the reverse direction can be easily achieved without any trouble.

Next, the blind function in the outer window / inner window structure of the present invention will be described with reference to FIG.
FIG. 3 is a plan view seen from the indoor side, showing the arrangement of the polarizing film attached to the outer window portion and the glass surface of the inner window portion in the outer window / inner window structure of the present invention. FIG. 3A shows the glass surface of the outer window portion, and FIG. 3-B shows the glass surface of the inner window portion.

  FIGS. 3A and 3B show a state in which the glass windows in the outer window portion and the inner window portion are closed, respectively. 3A and 3B, the left glass surface (left surface) of the outer window portion and the inner window portion are both arranged so that the polarization direction of the polarizing film is the same. The right glass surface (right surface) is arranged so that the polarization direction of the polarizing film is the same for both the outer window portion and the inner window portion, but the polarization direction of the polarizing film is orthogonal to the left surface and the right surface. Thus, a polarizing film is arranged.

In the plan views of FIGS. 3A and 3B, the left and right surfaces of the glass surface are both provided with polarizing films that are polarized in the same direction, so that both the left and right surfaces of the entire window transmit light ( Bright state), it is possible to see the inside of the room from the outside and the inside of the room from the outside.
However, if the right and left glass surfaces in FIG. 3B are reversed (that is, when the left and right surfaces of the inner window portion are moved by sliding), the outer window portion and the inner window portion are both left and right surfaces. The polarization direction of the polarizing film becomes orthogonal, and light is not transmitted. That is, the entire window is in a blind state (dark state).

In order to attach the polarizing film to the glass surface, the polarizing film may be attached to the left and right glass surfaces of the outer window portion and the inner window portion so that the polarizing direction of the polarizing film is as described above. That is, when the outer window portion is a single layer glass, it is preferable to attach a polarizing film to the glass surface on the indoor side of the single layer glass window.
Moreover, in the case of a multilayer glass, it is preferable to affix a polarizing film on the glass surface of one inner side (space part side) of two glass plates.
