Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite structure for windows. More specifically, the present invention relates to a multilayer structure for windows having a multilayer structure including a flexible film stretched between two planar bodies.

Conventionally, in order to maintain a closed hot or cold space from the surrounding environment, it has been done to use multiple windows, such as double or triple windows, on the surface that partitions the space from the surrounding environment. .

These days, when energy conservation is attracting a lot of attention, there is a need for such multi-layered windows, not only in areas with harsh natural environments, but also in areas with relatively warm natural environments, or in environments where careful consideration in various industries or industrial fields has a large impact. It is also gradually becoming larger.

Most of the multi-pane window structures actually used in the past have a plurality of glass plates arranged at intervals. Such multiple glazing satisfactorily accomplishes its purpose in maintaining a closed space from the surrounding environment.

However, if the material used for multi-layered windows is limited to glass plates, K will need to increase the number of glass plates in order to improve the heat insulation effect, and this will require reinforcement of the window frame that supports the multi-layered windows due to the increased weight of the multi-layered windows. In addition, there are problems that need to be solved in terms of cost, such as the need to increase the width of the window frame.

In order to solve the problem of multiple windows using glass plates, 2.
A structure in which at least one window panel of a multi-layer window is made of plastic (for example, see JP-A-52-86253) or a structure in which one window panel of a multi-layer window is replaced with a film (for example, JP-A-52-86253) 99635) has been proposed.

These window structures solve the problem caused by the increased weight of multiple windows with glass panes, but they do not go beyond simply changing the material of the window panes. It does not increase the thermal insulation properties compared to multi-paneled windows7, and soundproof windows are also known that have a structure in which a plastic sheet is placed between two glass panels at a distance from the glass panels. (Refer to Japanese Patent Application Laid-Open No. 53-97534).

In addition, insulating windows with a roll-up transparent film installed between two glass plates at a distance from the glass plate are conventionally used, but conventionally, a flexible film is installed between two glass plates at a distance from the glass plate. For multi-layer windows that have a structure in which the flexible film is fixed and stretched at a constant distance from the glass plate, it may be difficult to develop an appropriate means for stretching the flexible film. It seems that this has not been proposed yet. When stretching a flexible film, it is necessary that the image can be seen correctly without distortion, so it is necessary to do so so that the entire film does not become partially loosened or wrinkled during stretching. It is also necessary to take care of the thermal deformation caused by temperature differences over time that occurs after stretching, so that the above-mentioned local loosening, wrinkles, etc. can be eliminated.

JP-A No. 52-99636, which has already been introduced, relates to a multi-layer window with a structure different from the above-mentioned structure in which a flexible film is arranged between two glass plates. A means for expanding the is disclosed. That is, the stretching means is an elastic body that is previously deformed and attached as a support for the film.

However, the stretching means disclosed in JP-A-52-99635 expresses the restoring force of an elastic body on the film surface, and according to the research of the present inventor, such stretching means Sufficiently absorbs thermal deformation caused by temperature differences that occur over time, and loosens due to the thermal deformation.
It was found that this was not sufficient to eliminate the appearance of wrinkles and the like. Loosening and wrinkles in the film that occur over time after being rolled out are often serious defects in the structure of multi-pane windows, especially in multi-pane windows that are manufactured as a single unit where it is difficult to open and close the two panes of glass. It becomes a defect.

Therefore, the object of the present invention is to provide #
To provide a multilayer structure for a window, in which a flexible film located apart from two planar bodies is stretched so as not to loosen and wrinkle during and after stretching.

Another object of the present invention is to apply a force to a flexible film located away from the two planar bodies in a direction having an angle with respect to the film plane between two sheets of a plurality of planar bodies. expanded,
K provides a composite structure for windows.

Still another object of the present invention is to provide a window composite and a multilayer window unit including the structure as described above.

Further objects and advantages of the invention will become apparent from the description below.

These objects and advantages of the present invention, from its broadest aspect, include: a plurality of sheet bodies: a castable film located apart from each sheet body between two blows of the sheet body; ;
and a stretching member capable of exhibiting elasticity for applying a force in a direction having an angle to the film surface to stretch the flexible film, and the flexible film is A window characterized in that the planar body extending at least as far as the area of the cylindrical body serving as a window and existing on at least one film surface side of the flexible film is transparent or translucent. This is achieved by a multi-layer structure.

The window multilayer body of the present invention has a stretching member capable of exhibiting elasticity for applying a force to the flexible film in a direction having an angle with respect to the film surface to stretch the flexible film. Applying a force in a direction having an angle to the film surface means that the direction of the force applied from the IK crane to the film does not exist on the film surface. Therefore, such a force has at least a vector component of the force in the direction perpendicular to the film plane. When the film is stretched by applying such a force, the film is prevented from loosening or wrinkling over time, compared to the case where the force is applied in the direction of the film surface.

Furthermore, the film can be expanded very easily without causing odor, loosening, wrinkles, etc. during expansion.

In the present invention, the planar body extends 14 times in the vertical and horizontal directions, has a thin thickness compared to the length in these directions, but is easily broken or deformed when the four circumferences are fixed, and is separated from the object, such as a plate. The material of the material may be either inorganic or organic. For example, glass, acrylic resin, vinyl chloride resin, polycarbonate resin, etc. are preferably used as the material for the planar body in the present invention. Glass plates generally have excellent chemical or physical durability, and are therefore particularly preferably used when such performance is required.

The planar body in the present invention usually has a1 to 20-1, preferably O,S- to low, more preferably about 1 to about 101
11. Particularly preferred is a thickness of about 2 to about 6 cages.

In the window multilayer structure of the present invention, the planar body present on at least one side of the flexible film must have transparency to the extent that the presence of the flexible film can be confirmed. . In the present invention, when a planar body is transparent or translucent, it means that the planar body is transparent to the extent that the flexible film present on the back surface of the planar body can be seen through the planar body and confirmed with the naked eye. 5. By using the transparent or translucent planar body as described above in the window multilayer structure of the present invention, The absence of looseness, wrinkles, etc. of the flexible film can be confirmed from at least one side of the window multilayer structure.

In the present invention, a flexible film is one that extends in the vertical and horizontal directions, has an extremely small thickness compared to the length in those directions, and easily flexes when not supported or when an external force is applied. The two-dimensional state can be transformed into a three-dimensional shape (
In the present invention, the word film is used in its usual meaning. Thick films are preferably used.

The flexible film in the present invention can be transparent, translucent or opaque. Translucent or opaque flexible films may be advantageously used where there is no need to see through the window composite structure of the present invention or where it is desired to prevent what is on the other side from being seen through. . Transparent flexible films can be used in see-through window composite structures. Furthermore, these films may be colored, and may be a single film or a laminated film in which such films are laminated, and furthermore, these films may be colored to reflect light or heat. It may also be treated. The method of manufacturing such films is itself well known to those skilled in the art.

The flexible film can be made of, for example, polyolefins such as polyethylene and polypropylene; polyvinyl halides such as substituted vinyl chloride, polyvinylidene chloride, and polyvinylidene fluoride; aromatic materials such as polyethylene terephthalate, polytetramethylene terephthalate, and polyethylene dichloromethane. Aromatic polycarbonate containing bisphenols such as bisphenol A as a diol component; Poly l-cableamide.

Preferably, it is made entirely or based on a polymer such as a polyamide such as polyhexamethylene 7 dibamide.

A flexible film made entirely of the above-mentioned polymer can be used after being -axially stretched or biaxially stretched.

Biaxially stretched films of polyethylene terephthalate are strong and easily available, and films of polyolefins such as polypropylene and polyethylene are advantageously used because polyolefins exhibit unique properties against heat rays.

According to the present invention, it is possible to reflect heat rays as a flexible film.
By using a film that has the function of A multilayer window structure may be provided that exhibits barrier capabilities.

As a flexible film having a heat ray reflecting function, at least one substance selected from the group consisting of an elemental metal, a metal alloy, and a gold tetraoxide is coated on one or both sides of a flexible film made of the above-mentioned materials. Alternatively, a film formed of a thin layer of such a material in combination with a high refractive index dielectric may be advantageously used for 49.

Examples of simple metals include gold, @, copper, and aluminum, and examples of metal alloys include gold, silver alloys, and 4S.

Copper alloy, gold, steel alloy, platinum, silver alloy, platinum, silver, copper alloy.

Gold, silver, copper alloys, etc.

The metal oxide is, for example, indium trioxide (IntOi
) *Tin dioxide (8nO,), Cadmium
Tin oxide (Cd*5nO4) and the like.

The high refractive index dielectric is usually selected from an organic or inorganic material having a refractive index of L4 or more, preferably 1.6 or more, more preferably L8 or more, such as polymethacrylonitrile titanium oxide, bismuth oxide, zinc sulfide. , tin oxide, indium oxide, etc.

A flexible film on which a thin layer of metal oxide is formed, or a flexible film on which a thin layer of metal and a thin layer of high refractive index dielectric material are formed in combination, has a heat ray reflecting function and Despite having such a thin layer, the transparency is good. The thickness of the thin layer is preferably about 2000 to about 4000λ for metal oxides, and about sO to about 5ooX, especially about 75 to about 200X for metals alone.
is preferable, and for high refractive index dielectrics, about 50 to about SO 1 and about 100 to about 400X are preferable.

Flexible films made of polyethylene or polypropylene, especially polypropylene, with a thin layer having heat ray reflecting ability as described above formed on one side of the film, are suitable for flexible films made of polyethylene or polypropylene, especially polypropylene, because these materials have a low ability to absorb heat rays, that is, infrared rays. The extent to which heat rays passing through the film layer consisting of is not absorbed by the film layer but is reflected by the thin layer surface is extremely large. A flexible film made of such a material with a thin layer having heat ray reflecting ability formed on one side is a flexible film made of such a material with a thin layer formed on both sides of the film (regardless of the material). Shows almost the same heat ray reflective ability as film.

It is better to form a thin layer on only one side of the film than to form a thin layer on both sides of the film, since it is easier to form a thin layer on both sides of the film than on both sides. It is easy to see that it is excellent in terms of performance.

Formation of such a thin layer on a flexible film is carried out, for example, by a vacuum evaporation method or a sputtering method, and various such methods are already known.

In addition, a flexible film with a roughened surface or a flexible film with a thin layer of metal such as aluminum on one or both sides can also be used. Although these films are inferior in their ability to reflect heat rays, they are superior in their ability to block light transmission than the films described above with a thin layer of metal oxide.

The window composite of the present invention includes a plurality of planar bodies as described above and a plurality of planar bodies located between two of the plurality of planar bodies apart from the #2 planar body. It has a flexible film as described above. The flexible film may be present between all two planar bodies of a plurality of planar bodies, which are usually positioned so that the planes of the planar bodies are approximately parallel to each other, and It may be present in a part between the two. For example, when there is one planar body, the '13T111 film may be present both between the two formed by the three planar bodies, or only in one of them. A flexible film may also be present.

The flexible film needs to extend at least over the window area of the planar body. This is because the purpose of providing the dainty film is originally to expect a heat insulating effect through the area that constitutes the window of the planar body, that is, the area that forms the window.

In addition, the planar objects present on one side of the flexible film must be at least transparent or translucent. This means that all of the plurality of planar objects are transparent or translucent, not only when there is one planar object, but also when there are two or more planar objects.

If the planar objects on both sides of the flexible film are opaque, the existence of the flexible film can be recognized through the planar objects on either side of the film surface. Therefore, there is no point in stretching the flexible film. If all the planar bodies present on one side of the flexible film are transparent or semitransparent, then the planar bodies present on the other side of the flexible film are transparent, translucent, or translucent. It may be opaque or opaque.

The window multilayer body of the present invention has a stretching member capable of exhibiting elasticity for stretching the flexible film. The stretching member applies force to the flexible film in a direction that is at an angle to the film surface, thereby stretching the flexible film.

The extensible member may be made of a material that has its own elasticity and therefore can exhibit elasticity based on its own elasticity, or it may be made of a material that is not substantially elastic by itself.
However, depending on its shape, it can exhibit elasticity. It may be one. Such materials and geometries capable of exhibiting elasticity are well known per se to those skilled in the art and will become clear from the description below.

The stretching member fixes all or part of the primary fixing surface of the flexible film, that is, the film surface where the flexible film would be located if the flexible film was fixed without using the stretching member. Displace perpendicular to the surface. The flexible film is subjected to two directions (pushing force or attractive force) at angles to the film surface by the stretching member, and is displaced in the direction perpendicular to the film surface as described above, and as a result, there is no loosening, wrinkles, etc. It is expanded. Therefore, in the flexible film stretched by the stretching member, there are contact points between the wrinkle stretching member and the flexible film outside the plane of the primary fixing surface of the flexible film.

The stretching members are arranged around the four circumferences of the flexible film so that the force is applied almost equally to all four circumferences of the flexible film. For example, the spreading members may be arranged around the entire circumference of the flexible film, or they may be arranged only on two opposing sides of the flexible film. In this case, each spreading member has the length of one side of the film. The film may extend over the length of the film, or may be cut here and there along the length of one side of the film.

It is also possible to distribute power only to the four corners of the flexible film.

In the structure of the window multilayer body of the present invention, the flexible film is fixed so as to occupy a fixed position relative to the planar body. Such fixing may be performed, for example, on a sealing member that seals the two planar bodies at their entire periphery, or on a sealing member provided separately from the sealing member between the two planar bodies. The process may be performed on a spacer for defining a space interval, or may be performed on a film support provided separately from the sealing member or spacer. That is, the sealing member that fixes the flexible film in this way.

The spacer or film support is also arranged to occupy a defined position relative to the planar body.

The stretching member applies the force as described above to the fixed flexible film to stretch the flexible film so that it occupies a fixed position relative to the planar body. Therefore, in the structure of the window multilayer body of the present invention, the stretchable member is a flexible film fixed so as to occupy a fixed position relative to the planar body as described above. , incorporated into the composite structure in such a way as to be displaced perpendicularly to its secondary fixation surface, e.g. to a fixed sealing member, a spacer or a film support or a planar body or a flexible film. If the spreading member is fixed to a sealing member, a spacer, a film support or a planar body, the spreading member can be slidably attached to the flexible film. Desirably, contact is formed, whereas if the spreading member is fixed to a flexible film, it is desirable that the spreading member forms slippery contact with the planar body.

The invention will now be described in more detail with reference to FIGS. 1 to 13 of the accompanying drawings. In these figures, elements having the same function in the structure of the window composite of the present invention are given the same numbers.

The expansion member 17 is shielded over most of its entire surface by the shield portions 21, 21'Jg of the spacers 14, 14'. A shielded tension member is shielded from, for example, solar preloading and is protected from loss of elasticity due to photodegradation.

The flexible film 12 is fixed to one part 14 of the spacer via the adhesive part 2o as in the case of FIG. There is.

In FIG. 8, as in FIG. 7, there is a

@11 illustrates the structure of the window multilayer body of the present invention, in which the spreading member is integrally formed with the spacer. That is, before the spacer part 14' is attached to the structure of the present invention, as shown in FIG. 12, the spacer functional part 1411 develops elasticity and transmits the developed force to the flexible film Part 143
There is one consisting of and. Such a portion 14' can also be made of a material that itself has substantially no elasticity, such as a thermoplastic resin, a thermoset resin, or metal. When the part 14' is assembled into the structure shown in FIG. 11, the part 142 that exhibits elasticity deforms elastically, transmits the developed force to the flexible film AI 2 through the part 143, and Stretch the flexible film.

According to the present invention, there is therefore provided a multi-layered window body having the above-described structure comprising a conduit, a flexible film and an expansible member.

That is, the window composite of the present invention includes: a plurality of planar bodies; one or more hookable films located between two of the planar bodies and apart from each of the planar bodies; A stretching portion capable of exhibiting elasticity to stretch the hookable film by applying force in a direction having an angle to the film surface: Defining the interval of the space formed between opposing planar bodies.
It consists of a spacer and a sealing member that seals the space formed by several wrinkled sheet bodies at the entire periphery of the wrinkled sheet bodies.

As described above, the entire periphery of the window composite of the present invention is sealed with a sealing member.

The space formed by the two opposing planar bodies, the flexible film between them, and K may or may not be in communication with each other. As mentioned above, in the structure of the present invention, the stretching member applies a force to the film in a direction that is at an angle to the film holder. It is possible to use tensioning members which themselves exert relatively large forces on the film.

This means that even if a force is applied to either side of the flexible film in a structure in which the spaces S are not connected, or a force due to an external factor such as a rise in temperature is applied, the present invention can be applied. This means that the flexible film can still continue to expand against such forces due to external factors. When the space B formed by two opposing planar bodies and the flexible film between them is in communication, an increase in pressure due to a rise in temperature in one space will cause an increase in pressure between the space and the other space. Since it is averaged, forces caused by external factors act equally on both sides of the flexible film.

The space-○ communication can most easily be achieved by punching a hole in the flexible film λ (in a corner that is difficult to see with the naked eye). Of course, other spacers or the like may be provided with communication holes communicating with the rain space. The space l sealed by the seal member is filled with air (for example, argon,
SF, carbon dioxide.

An inert gas such as nitrogen can be filled.

Enclosure of such an inert gas further improves the heat insulation properties of the multi-layer window.

As the material for the sealing member, polysulfide, silicone, or butyl rubber resins, etc., which are conventionally used for double-layer glass, are used. Further, the multilayer body of the present invention may contain a conventionally used desiccant such as silica gel or molecular seeds in the space.

According to the present invention, there is also provided a multilayer window unit in which a plurality of planar bodies are supported on a window frame and a flexible film is fixed to the window frame or the planar bodies.

It consists of a stretching member capable of exhibiting elasticity to stretch the flexible film by applying a force in a direction having an angle to the film surface.

A multilayer window unit has a window frame that is assembled into a structure that becomes a window when attached to a building.

FIG. 13 shows an example of the multilayer window unit of the present invention.

In FIG. 13, window frames 31 and 31' each have a curved surface member, such as a transparent glass plate 11 and 11', attached with putty 30. The multilayer window unit F of the present invention including the window frames 31° and 31' can be opened and closed by a rotating means 32, but is normally fixed by a window frame fixing means 33, and is fixed to the outer frame 34iC by a multilayer window unit fixing means 35. be done. The distance between the planar bodies 11 and 11' is spacer 1
4. The flexible film 12 fixed to the window frame 31 by the film fixing means 37 via the film anti-slip 36 is moved from the bottom to the top in the figure from the spreading member 151C identified on the window frame 31' by, for example, adhesive. The power of is given and expanded.

The multilayer window unit shown in FIG. 13 is of a so-called linked window type, and one window frame can be opened and closed as necessary, but the multilayer window unit of the present invention is not limited to this type. That will be easily understood.

The multilayer structure for windows (including window coverings and multilayer window units) of the present invention has an extremely excellent heat insulating effect, and the flexible film does not loosen even after long-term use. Or it won't wrinkle.

For example, the multilayer structure for windows of the present invention uses a polybupylene film with a heat-reflective thin layer on one side as a flexible film, and places this film between two glass plates. , a heat transmission coefficient of approximately L5 or less, especially approximately L8 or less (unit: Keaj/
/・hr-deg). The heat transfer coefficients of regular glass and double glazed windows are about 44 and about 10, respectively.
Therefore, it is clear that the structure of the present invention exhibits extremely excellent heat insulation properties.

The structure of the window composite of the present invention can be applied to, for example, ordinary houses, buildings,
It can be advantageously applied to windows of vehicles, ships, aircraft, etc., or to viewing windows of refrigerated showcases, show windows, solar water heaters 9 heating elements, etc.
