Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating cover for a glass window such as a sliding door or a door attached to the glass window.

[0002]

2. Description of the Related Art Many buildings in recent years are provided with many glass windows for the purpose of lighting and ventilation. As a living space, in a house where comfort is pursued, glass windows in which glass plates are fitted to sliding doors, doors, walls, roofs, etc. are positively provided, and the presence of these glass windows makes it possible to use the room during the daytime. Is brightening. For example, having a door roller 9 and a frame 7,
An aluminum sash sliding door or the like having a glass window D, in which a glass plate W is fitted into 8 and then fixed by a bead or the like, is attached as a partition from the outside (FIG. 5).

[0003]

However, the glass window D
Due to this, the thermal energy of the time when the room was warmed during heating in winter was easily escaped to the outside through this. Recently, from the viewpoint of energy saving, walls and roofs are heat-insulated to improve the heating effect in the room, but the glass window D plays a role of daylighting, and it is difficult to take measures. Therefore, a large amount of thermal energy stored in the room was transmitted to the outside through the glass plate W.
Then, as the energy saving measures are advanced, the energy loss ratio in the glass plate W portion is increased. At night, by closing the shutters, etc., a temporary heat-retaining effect can be obtained, but if the shutters are closed during the day, it will not be possible to take in sunlight and it will be inconvenient for daily life, and the above energy loss must be endured. There wasn't. In addition, in the summer, when the indoor cooling is performed, the cooled room is warmed by the outside air through the glass window. Therefore, the glass window D deteriorated the cooling efficiency, which contributed to the increase of the electricity charge. On the other hand, when an earthquake or the like occurred, the broken glass pieces were dangerous because the human body had the ability to cut.

The present invention solves the above-mentioned problems and has a high heat insulating effect while having a sufficient daylight and taking in sunlight sufficiently in the room. Furthermore, the daylight heat insulating of a glass window is provided for earthquake countermeasures. Intended to provide a cover.

[0005]

The gist of the first invention is to be attached to a glass window in which a glass plate is fitted in a sliding door, a door, a wall, a roof, etc., and has a plurality of small chambers having a daylighting property. A daylight heat insulating cover for a glass window, comprising a heat insulating sheet made of a sheet-like member, in which air is enclosed in each of the small chambers, and a joining member fixed to the glass window. Here, the "sheet-like body having a daylighting property" is not limited to being transparent, and may be a semi-transparent sheet that satisfies the requirements as long as it is a sheet-like body that can transmit light. The "sheet-shaped body" includes a plate-shaped body and a film-shaped body.

The daylight insulation cover for a glass window according to the second aspect of the present invention is provided with a frame body for fixing and holding the heat insulating sheet according to the first aspect in a planar shape, and a joining member for fixing the heat insulating sheet to the glass window. is there. In the daylight insulation cover for a glass window according to the third aspect of the present invention, the frame body according to the second aspect of the present invention is made of synthetic resin and has a grid-like substrate frame, and the joining member is constituted by a double-sided adhesive tape. Further, the daylight insulation cover of the glass window of the fourth invention is one in which a handle is formed on the frame body in the second invention and the third invention.

A fifth aspect of the present invention is, in claim 2, the frame body is formed in a band shape having a hinge portion along a center line, and is bent at the hinge portion and fixed to both surfaces around the heat insulating sheet. It is in the daylight insulation cover of the glass window that was designed to be used. In addition, the lighting insulation cover of the glass window of the sixth invention,
A frame body according to a fifth aspect of the present invention includes a hinge portion along a center line and plate-shaped portions arranged on both sides of the hinge portion, and the frame body is joined to the heat insulating sheet on the plate-shaped portion. A double-sided adhesive tape for use is attached. The glass window lighting insulation cover of the seventh invention is the fourth invention or the sixth invention, wherein the whole shape in which the heat insulation sheet is fixedly held on the frame is a plate-like body, and the thickness thereof is within the range of 3 mm to 12 mm. It has been set.

If a heat insulating sheet in which a plurality of small chambers are filled with air is provided like the daylight insulating cover of the glass window according to the present invention, the air has a very small thermal conductivity, so that the glass is kept in the heat insulating sheet portion. By covering the window, the heat insulating effect can be enhanced. The inside of which the glass window is attached shields the glass window portion where heat transfer with the outside is large, so that the cooling and heating of the room can be made efficient. On the other hand, since the heat insulating sheet has a daylighting property, even if the daylighting heat insulating cover according to the present invention is attached to the glass window, the room will not become dark.

If the frame body is made of a synthetic resin and has a lattice shape and the joining member is composed of a double-sided adhesive tape like the lighting insulation cover of the third aspect of the invention, the manufacturing is simplified, and the glass window of the lighting insulation cover is provided. Installation becomes easier. When the handle is formed on the frame body like the daylighting heat insulating cover of the fourth invention, the daylighting heat insulating cover can be easily attached to and removed from the glass window.

Further, in the case of the heat insulation cover of daylight according to the fifth aspect of the invention, the frame body is fixed at the heat insulating sheet by bending at the hinge portion, so that the workability of attaching the frame body is improved. When the lighting insulation cover of the sixth invention is configured, the holding force is improved in the plate-shaped portion of the frame body, and when the lighting insulation cover is assembled,
If the release paper of the double-sided adhesive tape is peeled off, it can be easily fixed to the heat insulating sheet, so the workability is further improved. Further, like the daylighting heat insulating cover of the seventh invention, the whole shape in which the heat insulating sheet is fixedly held on the frame body is a plate-like body and has a thickness of 3 to 12 m.
If it is within the range of m, even if it is in the sliding door, both sliding doors can be moved for the purpose of ventilation etc. with the lighting insulation cover attached, so that the inconvenience caused by the installation is not felt. Since the daylighting heat insulating cover of the present invention is usually installed on the indoor side of the glass window, even if the glass plate is broken due to an earthquake or the like, the glass fragments are prevented from scattering into the room.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a glass window heat insulating cover (hereinafter referred to as "light insulating heat cover") according to the present invention will be described in detail below. (1) Embodiment 1 FIGS. 1 to 4 show an embodiment of a daylighting heat insulating cover according to the present invention. FIG. 1 is an exploded perspective view of the daylighting heat insulating cover.
FIG. 2 is a vertical cross-sectional view showing a state in which a daylighting heat insulating cover is attached to a glass window, FIG. 3 is a perspective view of a main part of FIG. 2, and FIG. 4 is a partial cross-sectional view showing three modes of a heat insulating sheet constituting the daylighting heat insulating cover. .

The heat insulation cover A includes a sliding door, a door, a wall,
It is attached to the glass window D in which the glass plate W is fitted on the roof (it is attached to the upper half of the aluminum sash sliding door shown in FIG. 5), and the heat insulating sheet 1, the frame 2 and the joining member 3 Consists of.

The heat insulating sheet 1 is made of a transparent synthetic resin film. In this embodiment, of the two films shown in FIG. 4A, a large number of small convex portions are provided on one surface of one film, and gas 4 is formed on the small convex portions.
(Here, air), and the other film 13
Are bonded to the flat portion 12 of the film to form the small chambers 11, 11, .... The heat insulating sheet 1 has been generally used as a cushion material. The small chamber 11 is a substantially hollow cylindrical body having a diameter of about 9 mm and a height of about 3 mm, and the small chambers 11, 11, ...
Many are arranged in a staggered arrangement with a pitch of about 11 mm. As the synthetic resin film material constituting the heat retaining sheet 1,
It is desirable that the airtightness is high so that the air 4 enclosed in each of the small chambers 11 can be retained. From this point, a film such as a polyethylene film or a vinylidene chloride film is suitable.

The heat insulating sheet 1 is provided in each of the small chambers 11, 11,
What is necessary is just to form ... and enclose gas in it.
In addition to (1) of FIG. 4, for example, the structure shown in (2) of FIG. 4 or (3) of FIG. 4 may be used. The heat insulating sheet 1 of (2) in FIG. 4 is slid between the small chambers according to FIG. 4 (1) so that the small chambers containing the air 4 always pass when traversing the heat insulating sheet 1, and the film 13 is placed between them. Take the form of sandwiching and pasting. The heat retaining effect is more excellent than that of FIG. 4 (1). The heat insulating sheet 1 shown in FIG. 4C is a transparent resin plate 1.
5 (16) and the transparent resin plate 17, the hollowed resin inclusion 14 is disposed between the transparent resin plate 17 and the transparent resin plate 17, and the transparent resin plate itself maintains a flat state so that the small chambers 11, 11, ... To form. In this heat insulating sheet 1, unlike the heat insulating sheet 1 made of the film, the transparent resin plates 15, 1
6 and 17 have a shape retention force for keeping a flat surface, and the role of the frame body 2 (described later) for keeping the heat retaining sheet 1 in a flat shape is reduced. Therefore, it is possible to directly attach the joining member 3 to the heat insulating sheet 1 and to form the heat insulating cover A only by this.
In order to prevent convective heat transfer of air in the small chambers, each small chamber 11,
It is preferable that each of 11, ... Independently forms a closed space, but the small chambers may communicate with each other. Then, the resin inclusions 14 may be arranged only to prevent the transparent resin plates 15 and 16 from bending, and the small chambers 11 may be largely integrated into one or several. Although not shown here,
In addition, the heat insulating sheet 1 has a honeycomb structure and a small chamber 11
May be formed.

By the way, the thermal conductivity of air is about 0.
It is 02 [kcal / mhr ° C], and the thermal conductivity of the glass plate is about 1/30 of that of 0.62 [kcal / mhr ° C]. For this reason, even in a small chamber having an air layer of a slight thickness, it is comparable to the case where a glass plate having a thickness 30 times that of the small chamber is provided, and the heat retaining effect is significantly improved.

The frame body 2 is a rectangular lattice-shaped substrate frame 22 made of a thin plate and one surface side from the outer peripheral edge (see FIG. 2).
It is a synthetic resin molded product (vinyl chloride resin or the like) integrally formed by compression molding with a frame frame 21 having a width of about 5 mm that bends to the right). The frame 2 spreads the soft heat insulating sheet 1,
This is made flat and fixed and held. The size of the frame body 2 is made to coincide with each glass window D. The whole shape in which the heat insulation sheet 1 is fixedly held on the frame body 2 is a plate-like body,
The thickness is about 5 mm, but the preferred thickness range is 3 mm.
mm to 12 mm. When the thickness is 3 mm or less, the thickness of the frame body 2 is required to be about 2 mm, so that the height of the small chamber of the heat insulating sheet 1 is limited to 1 mm or less, and the heat insulating effect cannot be expected so much. This is because it is impossible to open and close the sliding door for the purpose of ventilation. A more preferable range of the thickness is 5 mm to 10 mm in consideration of the heat retention effect, workability, usability and the like.
Is. When the frame 2 has a thickness of about 10 mm, the locking piece 62 portion of the lock 61 according to the lock 6 is cut out by cutting out that portion of the frame 1 to cover the entire glass window D. It can be configured (Fig. 3).

The frame frame 21 prevents lateral displacement and the like when the heat insulating sheet 1 having the above-mentioned predetermined size is adhesively fixed to the substrate frame 22, and the resulting daylight insulation cover A is attached to and removed from the glass window D or the like. It also plays the role of protecting the heat insulating sheet 1 when it is carried out. The frame frame 21 is inclined outward from the substrate frame 22 as shown in FIG. The glass window D to which the daylighting insulation cover A is attached has the pressing bead 5 which fixes the glass plate W, so that the daylighting heat insulation cover A can be attached to the glass window D exactly. This is because Code 21
Reference numeral 1 is a handle attached at two positions on both sides of the frame 21 by post-processing. The handle 211 is used to attach and detach the daylight insulation cover A to the glass window D. Since the handle 211 has a height restriction, it is placed along the heat insulating sheet 1. The reason why the substrate frame 22 has a lattice shape is that it does not interfere with the light collection and that the heat insulating sheet 1 contained in the frame 2 does not stick out of the frame. By the way, from the standpoint of sufficiently exhibiting the daylighting insulation cover A's daylighting function, it is preferable to employ a transparent resin for the frame body 2.

The substrate frame 2 relating to the frame body 2 facing the glass window D when the daylighting insulation cover A is attached to the glass window D.
A double-sided adhesive tape 3a as a joining member 3 is attached to the position 2 at an appropriate position (FIG. 2). By using such a double-sided adhesive tape 3a, the daylighting insulation cover A can be easily attached to the glass window D simply by peeling off the release paper. In addition, when the air-conditioning period has passed and the season for removal has come, this time, simply pull on the handle 211 to pull the glass window D.
It is possible to remove the daylight insulation cover A without leaving a trace on.

The heat-insulating cover A having the above-mentioned structure is
Since it is lightweight, it can be easily attached to the glass window D by the double-sided adhesive tape 3a serving as the joining member 3. By this attachment, the air 4 enclosed in the heat insulating sheet 1 has an extremely low thermal conductivity as described above, and therefore exhibits an excellent effect as a heat insulating material. In an experiment in which the lighting insulation cover A as a prototype was attached to all the glass windows D, it was confirmed that the room temperature during heating was kept 4 to 7 ° C. higher than that in the case where this was not attached. It is considered that the heat energy escaping to the outside could be reduced while using the same heat source. Further, conventionally, a large amount of dew condensation was observed on the glass plate W when the daylighting heat insulating cover A was not provided, but when the daylighting heat insulating cover A was attached, almost no dew condensation was observed.

Even when the heat insulating cover A was attached to the glass window D, the sunlight of the sun did not fall and the room could maintain a constant brightness. Furthermore, this daylight insulation cover A
Even if it is a sliding door or the like, it does not interfere with opening and closing by being attached to the glass window inside the room, so it has an advantage that it can last long without being exposed to wind and rain unlike a screen door. in addition,
As described above, the daylighting heat insulating cover A has a simple structure of enclosing inexhaustible air in the small chamber 11, which is effective for heat insulating measures, and has an advantage that it can be manufactured at low cost. On the other hand, even if the glass plate is broken due to an earthquake or the like, the lighting insulation cover A attached to the inside of the room prevents the glass fragments from entering the room, so that it is possible to avoid a situation where the glass fragments cause an injury.

(2) Embodiment 2 In this embodiment, a heat insulation cover for daylight is provided as shown in FIGS. The heat-insulating cover A comprises a heat insulating sheet 1, a frame body 2, and a double-sided adhesive tape 3a as a joining member 3, and one surface of the double-sided adhesive tape 3a is attached to the frame body 2 (FIG. 6). Here, the daylight insulation cover A is sold as an assembled set product of the heat insulating sheet 1 and the frame body 2 with the double-sided adhesive tape 3a bundled as shown in FIG. 7 as a pre-finishing stage. It is also possible to take a product form that can be assembled to each other by cutting into a suitable size (Fig. 7).

The heat insulating sheet 1 of this embodiment is a transparent film obtained by sandwiching both sides of a molded film 18 provided with a large number of cylindrical small chambers 11, 11, ... It is a plate-like body (FIG. 8). Since both surfaces are covered with the films 19 and 19, the heat retaining effect is more excellent than that of the heat retaining sheet 1 according to the first embodiment, and the shape retaining ability of keeping the heat retaining sheet 1 in a plate shape is excellent. Such a heat insulating sheet 1 is generally used as a cushioning material, and is called “Airbag” (produced by Kawakami Sangyo Co., Ltd.,
The model number # 40L) is used. The material of the heat insulation sheet 1 is polyethylene. As the heat retaining sheet 1, it is preferable to increase the thickness of the molded film 18 and the films 19 on both sides to the thickness of the sheet from the viewpoint of the shape retaining property of the heat retaining sheet 1.

The frame 2 has a band-shaped body 2a in which plate-shaped portions 26, 26 are integrally formed on both sides with the hinge portion 25 in the center.
And a double-sided adhesive tape 2b attached to the plate-like portion 26 for bonding with the heat insulating sheet 1 (FIG. 7). The design surface side T of the frame body 2 has a hinge portion 25, plate portions 26, 26.
Both are flush with each other, and the plate-like portion 26 on the side sandwiching the heat insulating sheet 1 is raised. Then, the double-sided adhesive tape 2b is attached onto the raised plate-like portion 26. As shown in FIG. 7, the frame body 2 has an equal cross-sectional shape in the longitudinal direction, the length thereof is cut according to the size of the glass window, and the end portion is cut as shown in FIG. It becomes a component of A. The strip 2a of the frame 2 is made by compression molding, extrusion molding, or the like.

The hinge portion 25 is a strip-shaped portion including the center line of the frame 2 and extending along the center line. The hinge portion 25 is formed into a thin skin and has a hinge function, and the band-shaped frame body 2 can be bent at the hinge portion. Since the width L of the hinge portion 25 covers at least the side edge of the heat insulating sheet 1, the width L is equal to the thickness t ₁ of the heat insulating sheet ₁ in the plate-shaped portion 2.
There is a value obtained by adding two thicknesses t _{2 of} 6. In particular,
The width L of the hinge portion 25 is within the range of 3 mm to 12 mm. The plate portions 26 have a rectangular cross section and are provided on both sides of the hinge portion 25. The plate-shaped portion 26 has a certain degree of rigidity and is fixed to both surfaces around the heat insulating sheet 1. It is difficult to maintain the flatness even with the films 19 and 19 only with the heat insulating sheet 1, and the plate-like portion 26 surrounding the periphery of the heat insulating sheet 1 contributes to the maintenance of the flatness. In particular, the band-shaped body 2a is the hinge portion 2
5. It is integrated with the plate-like portions 26, 26 and further has a rectangular frame structure surrounding four sides of the heat insulating sheet 1, so that the heat insulating sheet 1 is assembled to the heat insulating sheet 1 without using a grid-like substrate frame. As a result, the daylight insulation cover A is kept in a plate shape.

The double-sided adhesive tape 3a, which is the joining member 3, is attached to the design surface side T of the one plate 26. However, the part to which the double-sided adhesive tape 3a is attached is the design surface side T
However, when fixing the daylighting heat insulating cover A having the frame 2 attached to the heat insulating sheet 1 on the glass window by folding at the hinge portion 25, the release paper 31 relating to the double-sided adhesive tape 3a is peeled off, and the glass plate W is removed. (See Figure 2). The double-sided adhesive tape 3a is cut into a predetermined size together with the cutting of the frame body 2 at the time of use. As shown in Figure 6,
The daylighting heat insulating cover A formed by fixing the frame body 2 around the heat insulating sheet 1 as described above in the first embodiment,
It is preferably in the form of a plate, and the total thickness thereof is preferably in the range of 3 mm to 12 mm, more preferably in the range of 5 mm to 10 mm.

By the way, although the belt-shaped body 2a of the present embodiment is made by integral molding, it is possible to use a divided structure as shown in FIG. 9 instead. In FIG. 9, an adhesive tape 2c having an adhesive portion n except for a central line portion e serving as a hinge portion 25 is prepared. Then, the narrow plate-shaped portions 26, 26 are adhesively bonded in two rows in parallel to the adhesive portion n, and the double-sided adhesive tape 2b is further attached to the plate-shaped portion 26 to form the frame body 2. There is. Then, by sticking the double-sided adhesive tape 3a to be fixed to the glass window on the front side (design surface side) of the frame body 2, the same function as that of the integrated body of the frame body 2 and the double-sided adhesive tape 3a can be obtained. can get.

The daylighting heat insulating cover A constructed in this way is
In addition to the effects of the first embodiment, the heat insulating sheet 1 substantially matches the height of the small chamber of the molding film 18, and both sides of the film 1 have the same thickness.
Since the flat surface is maintained by 9 and 19, it is possible to maintain a plate shape rather than having a single film on only one side, and it is easy to handle. Then, by covering with the films 19 and 19, more air is trapped in the heat insulating sheet 1, so that the heat insulating effect is further enhanced. Further, since the frame body 2 has the hinge portion 25 and the plate-like portions 26 are integrally provided on both sides of the hinge portion 25, if the hinge portion 25 is applied to the side edge of the heat insulating sheet,
The plate-like portions 26 can be firmly fixed to both sides of the heat insulating sheet. When the frame 2 is fixed to the heat insulating sheet 1, the double-sided adhesive tape 2b can be easily fixed by peeling off the release paper, which is excellent in terms of work. Furthermore, since the plate-shaped portion 26 surrounds the heat insulating sheet 1 in a quadrangle shape, the plate-shaped portion 26 is unlikely to be deformed, which helps to maintain the plate-shaped shape of the daylight insulation cover A. In addition, the weight of the frame 2 is reduced compared to the first embodiment, and even if the double-sided adhesive tape 3a is fixed to the glass window, the adhesion can be maintained for one season. Of course, as in the case of the first embodiment, even if the glass plate is broken due to an earthquake or the like, the daylight insulation cover prevents the glass fragments from scattering into the room and enhances safety.

The present invention is not limited to those shown in the above embodiment, but can be variously modified within the scope of the present invention depending on the purpose and application. The shape, size, material and the like of the heat insulating sheet 1, the frame body 2, the joining member 3 and the like are not limited to those in the embodiment and can be appropriately selected. For example, in the embodiment, the joining member 3
Although the double-sided adhesive tape 3a is used as the above, it goes without saying that it is not limited to these. In addition to the adhesive type, the joining member 3 having a locking mechanism may be used. The shape of the small chamber 11 can also enhance the design value of the daylighting insulation cover A by giving a designing graphic pattern. The substrate frame 22 of the frame body is not limited to the lattice shape, and may have a shape to be designed.

[0029]

As described above, the daylight insulation cover for a glass window according to the present invention has a simple structure, yet has a daylighting property to allow sunlight to be fully taken into the room, and has high performance as a heat insulating material. As a result, it has a great effect as an energy saving product for indoor cooling and heating, and also has an excellent effect as an earthquake countermeasure product.
