Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a roll screen used integrally with a window glass, and more particularly, to a closed multilayer roll screen or a window glass closed roll screen for improving the tightness of a window.

[0002]

[Prior art]

 Generally, in order to enhance the heat insulation effect of buildings and the like, it is necessary to minimize the emission and ingress of heat from openings such as windows. Conventionally, double glazing has been used for windows to enhance the heat insulation effect, and this double glazing is excellent in heat insulation and condensation prevention as a result of sealing the air layer between the glasses. .

[0003] In addition, since window glasses are generally transparent, blinds and the like are installed in the windows to shield the windows from outside and to block direct sunlight. Roll blinds are known as such blinds, and the blinds are raised and lowered as necessary.

[0004]

[Problems to be solved by the invention]

 As described above, when a multi-layer glass is used for the window glass, it has heat insulation and dew condensation prevention effects, but since the glass is transparent, it cannot be blindfolded from the outside and, furthermore, cannot be exposed to direct sunlight. It is also difficult to prevent.

[0005] On the other hand, the roll blind can blind from the outside and has an interior decoration effect and the like, but can only prevent direct sunlight. There is a problem that it is difficult to shut off the heat that enters the sea. Moreover, in winter, heating heat cannot be prevented from being released through the window glass.

[0006] In the case of using a double-glazed glass and a roll blind, both a heat insulating effect and a blinding effect can be obtained. However, work to make the window glass a double-glazed glass and installation work for a roll blind must be performed. However, there is a problem that the cost increases as a result. That is, as a result of separately providing the double-glazing and the roll blind, there is a problem that the installation cost is relatively high.

[0007] An object of the present invention is to provide a closed multilayer roll screen (or a film screen) that can obtain a heat insulating effect and a blinding effect at low cost.

[0008]

[Means for Solving the Problems]

 According to the present invention, a screen for providing a heat insulating effect and a light-shielding screen, which is a screen for providing a heat insulating effect and a light-shielding effect, comprising: A winding member disposed at an upper end portion for winding the screen portion, and guiding the lowering and winding-up of the screen portion and between the screen portion and the window glass when the screen portion is lowered. A sealed multilayer roll screen characterized by having a guide means for forming a sealed hollow layer is obtained. It is also possible to attach a heat ray shielding glass scattering prevention film to the window glass on the outer side, and further provide the above-mentioned screen portion.

For example, the winding member has a winding pipe wound by the screen portion, and a winding pipe box that houses the winding pipe and rotatably supports the winding pipe, The guide means includes a pair of guide rails disposed on both left and right ends of the window and extending in a vertical direction, and a slit portion is formed on each of opposing surfaces of the guide rail, and the slit portion has The side end of the screen part is inserted, and the screen part is guided by the guide rail. It is desirable to dispose a mohair-like sealing member in the slit.

[0010]

[Embodiment of the invention]

 The present invention will be described below with reference to the drawings.

Referring to FIG. 1, a window frame (for example, a float plate glass) 12 is fitted into a window frame 11 to form a window 13. This window 13 is an existing window.

For example, a metal-coated polyester film 14 is attached to the inner side surface (indoor side) of the window glass 12. The metal-coated polyester film 14 has a glass scattering prevention effect of preventing glass from scattering when the window glass 12 is broken. That is, the heat ray shielding glass scattering prevention film is attached to the inner side surface of the window glass 12.

Referring to FIGS. 2A to 2C, as shown in FIG. 2A, a take-up pipe box 15 extending in a horizontal direction in the figure is attached to an upper portion of the window 13. 2 (a), a winding pipe 16 extending in the lateral direction is disposed in the winding pipe box 15. Rotation support portions 16a are formed at both ends of the winding pipe 16. The winding pipe 16 is rotatably supported by the winding pipe box 15 by the rotation support portions 16a.

In FIG. 2A, guide rails 17a and 17b extending downward are attached to the left and right window frames 11, respectively. The guide rails 17a and 17b allow the roll screen (as described later) to be used. A film screen 18 is guided. The roll screen 18 has a heat insulating property and a light shielding property.

As shown in FIG. 2B, an upper end of the roll screen 18 is fixed to the winding pipe 16, and the roll screen 18 is wound on the winding pipe 16. A bottom 18a is attached to the lower end of the roll screen 18, and the bottom 18a is made of, for example, aluminum.

As shown in FIG. 2C, the guide rails 17a and 17b are hollow and have a rectangular or square cross section. Slits 20a and 20b are formed on mutually facing surfaces 19a and 19b of the guide rails 17a and 17b, and a mohair-shaped sealing member 20c is planted on the inner walls of the slits 20a and 20b. Then, the left and right ends of the roll screen 18 are inserted into the guide rails 17a and 17b from the slit portions 20a and 20b, respectively, whereby the roll screen 18 is guided by the guide rails 17a and 17b. That is, if the roll screen 18 is pulled down with the bottom 18a, the roll screen 18 is pulled down, and if the roll screen 18 is pulled up with the bottom 18a, the roll screen 18 is pulled up. The opening and closing operation of the roll screen may be of a chain type. In this case, a groove may be provided at a required position of the rotation supporting portion 16a to wind the chain. The width of the slits 20a and 20b is substantially the same as the thickness of the roll screen 18, and the mohair-like sealing member 20c is planted on the inner walls of the slits 20a and 20b. When is lowered, a closed space (hollow layer) 21 is formed between the window glass 12 and the roll screen 18. On the other hand, the guide rails 17a and 17b are not limited to the above-mentioned hollow integrated type, and the window 13 side and the indoor side may be of a mutually engaged type (not shown). In this case, attachment and detachment of the roll screen become easy.

The film used as the roll screen 18 may be a generally used polyester film having a thickness of about 50 to 200 μm because a heat ray shielding glass scattering prevention film is attached to the window glass 12. If a metal-deposited film is used for the window glass 12), the heat insulation effect can be further enhanced.

Further, as the roll screen 18, a half-mirror-shaped translucent film, a milk semi-tone film that transmits light to prevent a line of sight, or a pattern-like film may be used.

In the winter, indoor heating heat can easily escape from the window. However, if a resin film is used for the roll screen 18, the air heated inside the room may have a low temperature because the resin film has the property of preventing air from entering and leaving. Can be easily prevented from being directly cooled on the window glass surface and radiated to the outside.

As can be easily understood from the above description, the closed multi-layer roll screen includes a heat-shielding glass scattering prevention film, a guide rail, and a roll screen that are attached to the window glass 12, and the existing window. Can be easily attached to Then, when the roll screen 18 is pulled down, a closed space is formed between the window glass 12 and the roll screen 18, whereby both a heat insulating effect and a blindfold effect can be obtained. In other words, the effect of both the double glazing and the blind can be obtained only by lowering the roll screen 18. Of course, if the roll screen 18 is raised, the field of view with the outside is opened, and the window can be freely opened and closed.

[0021]

[Effect of the invention]

 As described above, in the present invention, simply pulling down the roll screen forms an enclosed space between the window glass and the roll screen, which not only provides an extremely high light-shielding and heat-insulating effect, but also provides a blindfold. The effect is also obtained.

Further, by raising the roll screen, the field of view from the window can be made free. In this case, since the heat ray shielding glass scattering prevention film is attached to the window glass, the disaster prevention effect can be reduced. Can also be obtained.
