Description

The present invention relates to a heat shield material having a high reflective effect, which is attached to the back surface side (outdoor side) of a plain shade made of a curtain fabric, for example.

Conventionally, a heat shield material having a high heat reflection effect has been installed inside a building structure. Like the heat insulating material, they were mainly used for the purpose of keeping heat cool and warm. Further, the heat insulating material has a thickness of about several millimeters because there is a difference in superiority and inferiority depending on the heat reflectance, but the heat insulating material has a heat insulating performance of about several tens of millimeters even if it is thin.

Generally, the heat shield material has a shape in which a high heat reflection effect is expected on the surface and a heat insulating effect is expected in the inner layer. For example, aluminum foil with a high heat reflection effect is provided on both sides, and the inner layer of them is mainly made of a resin material such as polyethylene and has a shape that traps air, and is called an air cushion or bubble sheet. There is.

A technique for applying this heat-shielding material having an excellent heat-reflecting effect and a heat-insulating effect to a curtain is disclosed because a high energy-saving effect can be expected if it is applied to an opening of a window (for example, Patent Document 1). Patent Document 1 discloses a curtain in which an aluminum foil having excellent heat ray reflectance is used as a surface material and a material having low heat conduction such as a resin sheet is incorporated therein.

On the other hand, fabrics such as curtains and shades, which are installed at the openings of windows and are mainly used for lighting adjustment and blindfolding, are mainly fibers, and there are a wide variety of materials and color patterns, so designability is taken into consideration. There are plenty of choices. Some of them have a light-shielding function, but they are said to have an effect on heat-shielding performance, which is expected to save energy.

The plain shade, which is one of the Roman shades that opens and closes these fabrics up and down, has a structure in which the fabric in the middle portion is folded by moving the lower weight bar portion up and down by the elevating cord. The folding interval varies depending on their size and manufacturer, but it is basically determined by the interval of the guide ring, which is a member that penetrates the elevating cord.

The guide ring may be attached to a member called a ring tape in advance, which simplifies the manufacturing process. The plain shade may have irregular folding methods depending on the material and mass of the fabric, and in order to sharpen the folding up, it is a high-end type with a shaper added between the elevating cord guide rings. There is also a shade called.

Since a member called a shaper is installed in the middle between each guide ring, a plurality of members are installed, but the longer the production length, the more the installation location is required. Most of them are made of resin and have a rod-like shape, and are attached to the middle between the guide rings one by one.

Next, the fabric installed on the back surface of the plain shade is for providing a lace function, and is a unique fabric that has a blindfold function from the outside and can also obtain daylight. They are unique to each, such as drape curtains and lace curtains, but they are usually installed in pairs.

JP-A-2007-303262

The curtain of Patent Document 1 uses aluminum foil having excellent heat reflectance on both surfaces and has a resin sheet or other material with low heat conduction built in, so a thickness of about several millimeters is required. Therefore, folding and winding are extremely difficult, and there is a problem in the opening / closing function, which is the original function of the curtain. Further, since the color of the aluminum foil having excellent heat ray reflectance is a metallic color such as aluminum or silver, there is a problem in designability. Therefore, even if the curtain is manufactured by using the material disclosed in Patent Document 1 as it is, there are problems in the design and the opening / closing function which is the original function of the curtain, so that it is commercialized. Was extremely difficult.

On the other hand, the plain shade, which is popular as one of the interior items that enhance the decorativeness of windows recently, has a high design, but the fabric used for them has some effect on heat insulation performance, but there are also fabric materials. The effect is insignificant.

Depending on the material and mass of the fabric, the plain shade may be folded indefinitely and may be out of order, which impairs the design effect. Also, if the folding position is set casually, compact folding will not be realized. Sharp shades are intended to improve them, but they are expensive due to the addition of a shaper member between the guide rings for passing the lifting cord in order to sharpen the folding up, which adds to the manufacturing process and cost. It was.

Next, the fabric installed on the back of the plain shade is a unique shade that can be operated independently mainly to bring about a translucent lace function, and there was nothing specially installed as an energy saving measure as the lining of the plain shade. ..

The present invention was made in view of the above problems, and is a sheet-like heat shield material composed of a multi-layer structure in which multiple resin sheets are built in high-purity aluminum foil on both sides to trap air. Therefore, it is an object of the present invention to provide a heat shield material that can be easily folded.

In order to achieve the above object, the present invention is a sheet-like heat shield material composed of a multi-layer structure in which a plurality of resin sheets are embedded in high-purity aluminum foil on both sides to confine air. Horizontal streaks are applied at predetermined intervals to enable folding. In the streaks, the heat shield is heat-welded from the outside of the surface by a heat welding machine, and the inside of the heat shield is heat-welded. Provided is a heat shield material characterized in that it is performed by melting and crimping only the resin sheet of. In the plain shade provided with the heat shield material of the present invention, a horizontal streak for opening and closing is possible on almost the entire back surface side (outdoor side) of the plain shade made of curtain fabric. It may be characterized in that a sheet-shaped heat-shielding material having a high heat-reflecting effect, which has been subjected to attachment processing at predetermined intervals, is attached and fixed.

With such a configuration, while obtaining a high cold and heat insulating effect, the high design of the plain shade made of the conventional curtain fabric and the advantage of being able to select from abundant fabrics are secured, and the conventional plain shade is further made of the fabric. It is possible to eliminate indefinite and irregular folding when folding and to fold sharply.

Further, in the present invention, the heat shield material is composed of a multi-layer structure in which a plurality of resin sheets are built in high-purity aluminum foil on both sides to trap air, and the heat shield processing is heat shield processing. The material is heat-welded from the outside of the surface with a heat-welding machine, and only the resin sheet inside the heat-shielding material is melted and crimped.

With such a configuration, the scoring process can be easily performed by the heat welding machine, and as a result, the manufacturing cost is low, so that it can be provided to general consumers at a low price.

Further, in the present invention, a guide ring for passing an elevating cord for operation in the vertical direction is provided on the back surface side (outdoor side) of the plain shade in the vertical direction at least at the left and right ends and the center. A large number are provided at each interval, and the heat shield is lined in the horizontal position and the horizontal position connecting the guide rings at the left and right ends and the center provided in the horizontal direction of the plain shade when attached to the plain shade. It may be characterized in that it is performed at a horizontal position lower than the center of the space by the thickness of the heat shield material.

With such a configuration, the conventional plain shade does not fold up irregularly and irregularly due to the fabric, and sharp folds and compact folds without protruding to the front side are realized. In addition, the shape is as sharp as the sharp shade, which is a higher type of plain shade, which improves the sense of value.

Further, in the present invention, the heat shield material has vertical cuts slightly larger than the size of the guide ring formed at all positions of the plurality of guide rings attached to the plane shade in the state of being attached to the plane shade, and moves up and down. The guide ring attached to the plain shade provided in the horizontal direction to pass the cord in the vertical direction is rotated in the vertical direction, and is inserted into the vertical notch formed in the heat shield and penetrated. After that, the heat shield material may be fixed to the plain shade by returning it to the lateral direction and passing the elevating cord through the guide ring.

With such a configuration, the heat shield material which is the lining of the plain shade is surely fixed without being separated from the plain shade main body. Moreover, since it can be easily attached and detached, it can be easily cleaned when the plain shade body becomes dirty.

Further, the present invention is also characterized in that a lining having a low heat-shielding effect and making it difficult to see the heat-shielding material from the back surface side (outdoor side) is arranged on the back surface side (outdoor side) of the heat-shielding material. good.

With such a configuration, it is possible to make it difficult to see the heat shield material, which is inferior in design, from the back surface side (outdoor side) by using the lace type, which is the original purpose of being able to adjust the lighting.

According to the present invention, there are many similar applications due to the reason that the heat shield material that can obtain a high heat reflection effect has poor design and the problem of bulkiness at the time of storage due to the thickness of several millimeters. Despite this, it was not commercialized, but the present invention is a sheet-like structure composed of a multi-layer structure in which multiple resin sheets are built in high-purity aluminum foil on both sides, which has a high heat reflection effect, to trap air. The heat shield material can be easily folded by the streaking process. By specializing this heat shield as a plain shade lining used for window openings, these problems can be solved, and with a unique processing method and mounting method that can be installed in existing plain shades. It is realized at low cost. While achieving high energy-saving effect and maintained design at low cost, blindfolding and daylighting for privacy protection by the opening and closing function, which is the original purpose of the curtain, can be established without any problem.

It is a figure which shows the overall shape of this invention, and shows the state that the heat-shielding material A processed for installing on these is installed on the back surface of the plain shade main body cloth G. A ring-shaped B, which is an important component, is shown in the lower right of the drawing. It is a figure which shows the side surface of FIG. 1, and shows the direction of the front surface O (indoor side) and the back surface U (outdoor side) of the plain shade main body cloth G. A ring-shaped B, which is an important component, is shown in the lower right of the drawing. The flow YO of the heat welding process in which the heat shield material A is sandwiched between the heat welding machines YU and YD, only the resin material portion inside the heat shield material is melted and crimped, and the surface of the heat shield material is lined is shown. FIG. 3 is a diagram showing a part of the position where the processing of FIG. 3 is performed, and shows a welded portion C3 in which the guide ring B is in contact and a C2 position which is an important position of claim 3. These particularly indicate that the lower side is heat-welded from the position lowered by the thickness of the heat-shielding material from the center between C3 and the adjacent C3. It is a detailed view of the flow of installing the heat shield material A on the cloth G of the plain shade main body. The important steps in the work of inserting the guide ring B into all the guide rings B are shown. A plain shade for making it difficult to see the heat shield material A installed on the back surface of the plain shade main body fabric G according to claim 5 from the back surface side U (outdoor side). In order to insert and install the guide ring B in the heat shield material A, a state in which a notch in the vertical direction slightly larger than the guide ring B is provided in the portion where the guide ring B is in contact with the heat shield material A is shown. FIG. 7 shows a state in which the heat shield material A, which is a side view of FIG. 7, is installed on the plain shade main body fabric G.

Hereinafter, the plain shade provided with the heat shield material according to the embodiment of the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 and 2, a sheet-shaped heat shield material A is fixedly installed on the back surface side U (outdoor side) of the plain shade main body fabric G. The guide ring B and the elevating cord D, which are ancillary parts of the plane shade G connected to the plane shade G, penetrate the heat shield material A and are installed on the back surface side U (outdoor side) of the heat shield material A. The heat shield material A is integrated as a lining.

Further, the heat shield material A is subjected to horizontal scoring processing C2 and C3 to enable folding necessary for opening and closing. Since the heat shield material A is a multi-layer structure in which a plurality of resin sheets are built in aluminum foil on both side surfaces to confine air, horizontal scoring processing C2 and C3 can be processed by a heat welding machine. As shown in FIG. 3, these are streaks C in which the heat shield material A is sandwiched between the upper YU of the heat welding machine and the lower YD of the welding machine, and the heat shield material is welded by YO showing the flow after welding.

As shown in FIG. 4, the processing positions of the horizontal streaks C2 and C3 are specified by the positions of the guide rings B installed on the back surface side U (outdoor side) of the plain shade G. The horizontal position C3I of the position where the guide ring B is installed is subjected to the scoring process of C3, and the C2I is heat-welded in the horizontal direction to the position where the thickness AA of the heat shield is lowered from the central portion between the upper and lower C3Is. These are the positions calculated to be compactly folded by suppressing the protrusion to the O side because the area below the central part is of an appropriate shortness.

Next, the procedure for attaching and fixing the heat shield material A to the back surface side (outdoor side) of the plain shade G is shown as shown in FIG. As shown in FIG. 7, a cut BK is vertically made in all the position BIs where the guide rings B installed on the back surface side U (outdoor side) of the plain shade G are installed in the heat shield material A in advance. The notch BK is slightly larger than the diameter of the guide ring B. Further, the elevating cord D, which is an accessory part of the plain shade G, is removed from the guide ring B.

Next, as shown in FIG. 8, a sheet-shaped heat shield material A having a notch BK formed is attached to the back surface side of the plain shade G. The BK, which is a vertical cut, is rotated BC from the fixed position horizontal direction of the guide ring B installed in the plane shade G in the vertical direction (FIG. 5-1) and penetrated from (FIG. 5-2). At that time, it is made easier to penetrate by the work BH that widens the notch BK. The guide ring B after penetrating them is rotated BM in the lateral direction and returned to the original fixed position (Fig. 5-3). Finally, the elevating cord D is passed through the guide ring B to return to the original state. By these operations, the heat shield material A is fixed to the plain shade G without detaching.

Further, as shown in FIG. 6, in the first place, the plain shade has a unique shade called twin or double, which has a race function and can be operated independently, but in the case of those types, the heat shield material A can be operated independently. The heat shield material A becomes difficult to see from the outside because it is hidden by the possible lace fabric. In this way, by arranging a lace lining on the back surface side (outdoor side) of the heat shield material, which has a low heat shield effect and makes it difficult to see the heat shield material from the back surface side (outdoor side), the heat shield of the heat shield material is heat-shielded. It is possible to make the heat shield material, which is inferior in design, difficult to see from the back surface side (outdoor side) without reducing the effect.
