Description

Venetian blinds {BENETIAN BLIND}

The present invention relates to venetian blinds, and more particularly, to a venetian blind having an excellent light shielding effect, which is composed of a surface layer, a back layer, and a black film layer connecting the surface layer and the back layer.

In general, light-control blinds are used for home privacy, sun protection and sun protection in homes, hotels, restaurants, and other buildings.In general, curtains, vertical or horizontal verticals, and a certain width of fabric are cut and rolled. In this case, roll screens or panel screens are used, which are fixed to a window so that a user unwinds the roll to cover the window or winds the roll to secure a view. Each of these different types of blinds has its own advantages and disadvantages. For example, curtains are generally fabrics, which give a refined and cozy feel to the interior, while being inconvenient in cost and care, vertical or Horizontal vertical rolls and roll screens are simple to install and convenient to use, but they are not elegant. In particular, conventional verticals have a disadvantage in that they are not fabricated because they are not fabrics.

Therefore, a new type of blind has been proposed to solve the problems of the various blinds as described above. In detail, a vertical venetian blind is proposed, which combines the merits of the fabric curtain to soften the atmosphere of the room and the merits of the vertical with ease of use. It offers a softer appearance and easier handling.

As a novel type of blind in the form of a vertical fabric made to solve the conventional problems as described above, there is, for example, US Patent No. 3,384,519. The blinds presented in this patent consist of two fabric layers spaced by movable parallel blades with each edge of a heat welded edge on one of the movable fabric layers, the relative movement of the two fabric layers in a direction perpendicular to the blade It consists of blinds that modify the angle of the blade to control the amount of light entering through the article. However, the blinds disclosed in the patent are limited to the use of heat-weldable fabrics, that is, mutually suitable thermoplastic materials, because the blinds are constructed using a heat welding process, and heat welding must be performed because at least some of the fibers of the bonded material must be melted. There were disadvantages such as weakened structure.

Therefore, to solve the problems of the conventional patent, Korean Patent Application No. 193-0006097, "Method and Apparatus for Manufacturing Window Cover of Light Control Fabric", has been proposed. The Republic of Korea Patent Application No. 199-0006097 discloses "a first sheet material, a second sheet material disposed parallel to the first sheet material, at least one of the sheets is porous, and a plurality of strip materials are respectively opposed to the opposite surface and the Adhesive adhering means having opposing edge portions in contact with each opposing surface, the adhesive being injected into at least one of the sheet materials so that the strip is adhered to the sheet material along opposing edge portions so that the adhesive line is visually apparent Wherein the visible adhesive line has a matt appearance, the central portion of the strip being substantially planar in the first enclosed state of the window cover and extending substantially parallel to the first and second sheet materials and having a different window. A light control window cover " that forms a vane extending generally transversely to the first and second sheets in a second open state of the cover It discloses a Johann configuration.

However, although the above-mentioned patent solves the conventional problem to be solved, there is a concern that a substance harmful to the human body may be released for a long time due to the use of an adhesive, and also, there is a disadvantage in that the effective shading and aesthetic feeling in a closed state are inferior. .

Figure 1 shows a cross-sectional conceptual view in the open position of the Venetian blind according to a preferred embodiment of the present invention, Figure 2 shows a cross-sectional conceptual view in a closed position of the Venetian blind according to a preferred embodiment of the present invention.

The venetian blind according to the present invention is formed of a surface layer 100, a back layer 200 and a black layer 300 connecting the surface layer 100 and the back layer 200. The method of connecting the blackout layer 300 to the back layer 200 and the blackout layer 300 is not particularly limited, but is preferably connected by weaving with warp and weft.

In addition, the black film layer 300 is formed by combining the first black film layer 310 and the second black film layer 320.

The surface layer 100 and the back layer 200 and the blackout layer 300 according to the present invention may be formed of a fabric having a different density of tissue, respectively. The surface layer 100 and the back layer 200 may be made of the same material, the same structure, the surface layer 100 and the back layer 200 is a translucent material is preferably woven into a mesh fabric. When the surface layer 100 and the back layer 200 have a mesh structure, light can be efficiently transferred between the surface layer 100 and the back layer 200 at an open position of the blind and closed due to the translucent material of the surface layer 100 and the back layer 200. At this point, the blackout layer 300 can be seen. For this purpose, the spacing of the warp and the weft in the mesh structure is preferably set to 0.2 to 2mm.

In addition, the surface layer 100 and the back layer 200 may include an opaque thread forming a rectangular unit grid shape, the rectangular unit grid shape made of such an opaque thread can be implemented through, for example, a dark dyed yarn. . This is to prevent the interference effect caused by the moire phenomenon. The square unit grids of the surface layer 100 and the back layer 200 have the same size, but when the blind is faced in an open position, the squares of the surface layer 100 and the back layer 200 are the same. Do not overlap the unit grid. That is, based on the rectangular unit grid of the surface layer 100, the rectangular unit grid of the back layer 200 is formed at a position moved about 20 to 50% in the horizontal and vertical directions. As described above, when the rectangular unit grids of the surface layer 100 and the back layer 200 are not overlapped with each other, an interference fringe does not appear, thereby preventing a moire phenomenon. The unit grid shape of the quadrangle is preferably a quadrangle having a length of 3 to 10 mm between the mesh structure.

On the other hand, the black film layer 300 is preferably formed of an opaque material, it is preferable that the fabric formed in a denser structure than the surface layer 100 and the back layer 200. This is for shading or security through the blackout layer 300. When the blackout layer 300 is made of an opaque material or is made of a woven fabric, the light is hardly transmitted perpendicularly to the surface of the blackout layer 300.

In addition, it is preferable that the first blackout layer 310 and the second blackout layer 320 of the blackout layer 300 are made of fabrics of different colors. This is so that when in the closed position, the back layer 200 is visible and the surface layer 100 is visible in different colors.

Fabrics used in venetian blinds according to an embodiment of the present invention may be subjected to a heat treatment process to further improve the shape stability or to reinforce stiff physical properties. Preferably, the heat treatment can impart stiff physical properties to the fabric.

To this end, we can weave using a low melting point yarn to the warp and / or weft. The low melting point yarn intentionally lowered the melting point by a method selected from one or more of a method consisting of modifying the molecular structure, copolymerization, blending, spinning process control, complex spinning, the surface is subjected to heat treatment within a temperature range of about 120 to 190 degrees Celsius Any yarn having a property that can be finely fused can be used. Specifically, a copolyester-based binder fiber prepared by copolymerizing terephthalic acid or its ester-forming derivative and ethylene glycol and neopentyl glycol proposed in Korean Patent Invention No. 2,9414 may be used. In addition, the LM (Low Melting) manufactured by the compound spinning, the LM is a part where the core (core) to the local area and the sheath (fusion) sheath (fused) during heat treatment, the low melting point component proposed in Korean Patent Invention No. 587122 And a high melting point component, wherein the low melting point component continuously forms at least a part of the fiber surface in the fiber direction, and has a glass transition temperature of 60 ° C. or higher and 50 to 70 mol% of a polyethylene terephthalate unit. It is also possible to use a heat sealable composite fiber composed of a mixture of 99% by weight to 20% by weight of polyolefin.

On the other hand, warp and / or weft yarns may be used as a mixture of low melting point yarns and flame retardant yarns, or may be mixed fibers formed of low melting point parts and flame retardant parts (such as sheath-core type, split type, and multi-sea island type), or mixed yarns of low melting point yarns and flame retardant yarns. Can be applied to blinds. In this case, the ratio of the low melting point portion and the flame retardant portion or the low melting point yarn and the flame retardant yarn is preferably about 15:85 to 50: 50% by weight. If the flame retardant part (sa) is included below the ratio, the flame retardant effect is lowered, and if it is included in the above range, the low melting point (sa) is poorly fused at the time of heat treatment. .

On the other hand, as shown in Figure 1 can be said to be the open position when the black film layer 300 is perpendicular to the surface layer 100 and the back layer 200, the distance between the black film layer 300 and the adjacent black film layer is the same as "L". Formed at intervals.

 Further, the width of the blackout layer 300 is the length between the surface layer 100 and the backing layer 200 when the blackout layer 300 is vertically formed with the surface layer 100 and the backing layer 200 in the open position. The width of the black film layer 300 is formed as the same length, respectively "H". Therefore, the cross-sectional view of the blind in FIG. 1 is a result of the same width (H) of the plurality of black film layer 300, the surface layer 100 and the back layer 200 is in parallel with each other in a straight line.

In the present invention, the width H of the blackout layer 300 is preferably longer than the distance between the blackout layers L, more preferably 2 to 4 times larger, and the width H of the blackout layer 300 is the distance between the blackout layers ( Most preferably, it is twice as large as L).

As described above, when the width H of the blackout layer 300 is longer than the distance L between the blackout layers, when the blind according to the present invention is in a closed position (two-dimensional shape) (see FIG. 2), the blackout layer 300 is partially Overlap. For example, if the width (H) of the blackout layer 300 is doubled between the blackout layers (L), the blackout layer 300 is doubled, and the width (H) of the blackout layer 300 is three times the blackout layer (L). If so, the rock layer 300 is tripled. When the blackout layer 300 overlaps each other in such a closed position, light can be more effectively shielded.

In addition, in the blackout layer 300, it is preferable that the first blackout layer 310 and the second blackout layer 320 are made of fabrics of different colors, so that the Venetian blinds according to the present invention have different aesthetics depending on the viewing position. .

Fig. 2 shows a conceptual diagram in the closed position when the width H of the blackout layer is twice the distance L between the blackout layers. Looking at the blinds at the position of the surface layer 100, the surface layer 100 is a semi-transparent mesh structure, so that the visual influence is not very low, and the visual layer has a large visual influence. For example, when the first blackout layer 310 is formed of a woven fabric of red polyester yarn, and the second blackout layer 320 is formed of a woven fabric of black polyester yarn, when the blinds are viewed from the position of the surface layer 100 Since only the first black film layer 310 representing 311, 313, 315, etc. in the layer 300 is visible, the color becomes red. On the contrary, when looking at the blind at the position of the back layer 200, only the second black layer 320 representing 321, 323, 325, and the like is visible in the black layer 300, so that the black layer appears black. Therefore, when the blinds are seen at the position of the surface layer 100 and the position of the back layer 200, there is a characteristic that also has an aesthetic effect that appears in different colors. This can have the same effect even when the width (H) of the blackout layer is more than twice the distance (L) between the blackout layers, and thus the closed position when the colors of the first blackout layer 310 and the second blackout layer 320 are expressed differently. In the surface layer 100 and the back layer 200, the blinds appear different colors.

3 is a perspective view of an open position of a venetian blind according to a preferred embodiment of the present invention, Figure 4 is a photograph showing a venetian blind according to an embodiment of the present invention.

3 and 4 are manufactured so that the width (H) of the blackout layer 300 is twice the distance (L) between the blackout layer, in the open position the light passes under the influence of the surface layer 100 and the backing layer 200 made of a mesh structure. It is free and well ventilated. At this time, when light passes through, it is hardly affected by the blackout layer 300.

On the other hand, in the closed position, light is hardly passed by the influence of the opaque blackout layer 300, and the first blackout layer 310 and the second blackout layer 320 overlap each other to block light more effectively. do. In addition, in the photograph of FIG. 4, the right vertical layer may be referred to as the back layer 200. When the back layer 200 is lowered to a closed position, the blinds appear red in the back layer 200 position, and the surface layer is formed. At the position of 100, the blinds appear white and have a deep color effect.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be clear to those who have knowledge of.
