Description

Shading fabric capable of implementing two colors or functions and curtain-type vertical blinds using the same

[0001] The present invention relates to a light-shielding fabric capable of implementing two colors or two functions, and a curtain-type vertical blind using the same, and more specifically, to a light-shielding fabric capable of implementing one of two colors or functions by selecting the color or function depending on the rotation direction of a light-shielding part, a curtain-type vertical blind using the same, and a manufacturing method thereof.

[0002] In addition, the present invention relates to a shading fabric configured to allow adjacent shading portions of a curtain-type vertical blind to be in contact with each other by a magnet or a magnetic substance so that there is no gap between adjacent shading portions of the curtain-type vertical blind, and to a curtain-type vertical blind using the same.

[0003] In general, curtains and blinds are installed on the windows and entrances of buildings and are used for purposes such as blocking sunlight, blocking outside views, soundproofing, and keeping out cold. In addition to these practical purposes, they are also used as an important element of interior decoration that improves the appearance of the interior depending on the color combination that can be harmonized with the interior walls or glass.

[0004] These curtains or blinds can be classified according to their form, for example, into general curtains that unfold and fold from the center to both sides, vertical blinds that are divided into a number of vertically formed pieces so that the angle of inclination of the pieces can be adjusted, roll screen blinds in which one or two layers of blind paper are wound or unwound on a rotating winding rod, or Roman shade curtains in which the curtain paper is folded up and down by the winding action of a cord that adjusts the length.

[0005] Figure 1 illustrates a conventional roller screen blind. This roller screen blind operates by rotating a winding rod by a drive line installed on one side of the winding rod, thereby unwinding or winding up the roll screen. The front of the roller screen may face the interior, and the rear of the roller screen may face the exterior.

[0006] Figure 2 illustrates a conventional vertical blind. These vertical blinds open the openings of a building's windows or entrances by moving a plurality of vertical pieces to one side and gathering them together. When the vertical pieces are moved to the other side and unfolded, the outside scenery is exposed between the pieces, allowing ventilation. When the pieces are unfolded, the angles of the pieces can be adjusted to control the amount of sunlight or ventilation. When complete shading or wind protection is required, the angles of the pieces can be adjusted so that they are arranged horizontally in a single row. However, conventional vertical blinds, as illustrated in Figure 2, are comprised of a plurality of vertically formed blind pieces, allowing the interior to be observed through the gaps between the blind pieces, which makes them unsuitable for privacy protection.

[0007] To solve these problems, WO 2016 / 114516 discloses a shading fabric for curtain-type vertical blinds, which is woven as an integral part of a light-transmitting part and a non-transmitting part as shown in Fig. 3, so as to provide shading functions, privacy functions, decorative effects, and heat insulation effects. The central part of the shading fabric shown in Fig. 3 is formed of a light-transmitting part in the form of a mesh or net that can transmit light, and shading parts that can block light are formed on both sides of the central part.

[0008] When manufacturing a curtain-type vertical blind using the shading fabric illustrated in FIG. 3, as illustrated in FIG. 4, the shading fabric is cut into sections having a predetermined length, and then the upper portions of adjacent shading fabric sections are fixed while arranging them so that the shading portions of the sections are in contact. In this manner, a curtain-type vertical blind disclosed in WO 2016 / 114516, as illustrated in FIG. 5, can be manufactured.

[0009] However, since the shading fabric of the conventional curtain-type vertical blind of WO 2016 / 114516 has a shading section made of a single color or material, it is difficult to create a diverse indoor atmosphere. Furthermore, for example, if a curtain-type vertical blind in a bright color such as pink or sky blue is preferred, the pink or sky blue of the shading section of the vertical blind is directly exposed to the outside, which may not only damage the overall view of the apartment in a multi-family building such as an apartment, but may also cause a sense of discomfort or discomfort to others.

[0010] Furthermore, when complete shading or wind protection is required, and the blinds' shading elements are aligned horizontally, the angle should be adjusted to minimize solar heat transmission indoors in summer and maximize solar heat transmission indoors in winter. However, conventional curtain-style vertical blinds suffer from the inconvenience of not being able to adjust solar heat transmission characteristics depending on the season.

[0011] In addition, when fixing adjacent shading fabrics in a conventional curtain-type vertical blind, if one of the two shading sections is not fixed vertically, there may be a gap between the adjacent shading sections or the blinds may not be aligned properly, causing a problem in which sunlight comes in from outside.

[0012] Furthermore, since conventional curtain-style vertical blinds only secure the shading elements at the upper ends of adjacent shading fabrics, the adjacent shading fabrics may not be fully sealed and may have gaps. In this case, when the blind is opened wide enough to expose the light-transmitting portion, light may pass through the shading elements, allowing sunlight to enter from outside through the gaps between the shading elements, allowing the interior to be seen from the outside.

[0013] The present invention is intended to solve the problems of the prior art as described above, and the purpose of the present invention is to provide a curtain-type vertical blind light-shielding fabric that can create a variety of indoor atmospheres by selecting and implementing one of two colors depending on the rotation direction of the light-shielding part, and does not cause discomfort or discomfort to others, a curtain-type vertical blind using the same, and a method for manufacturing a curtain-type vertical blind.

[0014] In addition, the purpose of the present invention is to provide a shading fabric for a curtain-type vertical blind that can control the transmission characteristics of solar heat according to the season, a curtain-type vertical blind using the same, and a method for manufacturing a curtain-type vertical blind.

[0015] In addition, an object of the present invention is to provide a curtain-type vertical blind having one light-emitting portion and first and second light-shielding portions respectively disposed on one side and the other side of the light-shielding portion and attached or coupled to the light-shielding portion, wherein the adhesion between adjacent light-shielding portions is improved to prevent a gap between the light-shielding portions, and to prevent sunlight from entering between adjacent light-shielding portions and to prevent the interior from being seen from the outside.

[0016] In addition, an object of the present invention is to provide a curtain-type vertical blind having a structure in which a magnet or a magnetic substance is installed in a light-shielding portion to improve the adhesion between adjacent light-shielding portions and prevent a gap between the light-shielding portions, in a curtain-type vertical blind having a light-shielding portion and first and second light-shielding portions respectively disposed on one side and the other side of the light-shielding portion and attached or coupled to the light-shielding portion.

That is, the shading fabric can be a blind surface visible from the outside.

[0031] In a method for manufacturing a curtain-type vertical blind according to the fourth embodiment of the present invention, in the arrangement step, a separate shading part can be additionally placed on each of the outermost sides on the left and right.

[0032] In addition, in the method for manufacturing a curtain-type vertical blind according to the fourth embodiment of the present invention, in the fixing step, one or more through holes are perforated in the upper part of the first shading part of one section of the plurality of shading fabric sections and in the upper part of the second shading part of the other section, and a fixing means is coupled to the through holes to fix the upper part of the first shading part of the one section and the upper part of the second shading part of the other section together.

[0033] Meanwhile, in a curtain-type vertical blind according to an embodiment of the present invention, when the curtain-type vertical blind is unfolded, the first and second shading portions of the plurality of shading fabric sections are rotated in one direction about a vertical axis so that the front surfaces of the first shading portions are exposed to the outside to form a blind surface of a first color, and when the curtain-type vertical blind is rotated in a direction opposite to the one direction, the front surfaces of the second shading portions are exposed to the outside to form a blind surface of a second color.

[0034] Meanwhile, a curtain-type vertical blind manufactured by cutting the shading fabric for a curtain-type vertical blind according to a third embodiment of the present invention into a plurality of shading fabric sections of a predetermined length, and then arranging adjacent shading fabric sections so that the back of the first shading part of one section of the plurality of shading fabric sections and the back of the second shading part of the other section are in contact with each other, thereby fixing the upper end of the first shading part of one section and the upper end of the second shading part of the other section together, is such that when the curtain-type vertical blind is unfolded, when the first shading parts and the second shading parts of the plurality of shading fabric sections are rotated in one direction about a vertical axis, the front sides of the first shading parts are exposed to the outside, so that a light-reflecting layer forms a blind surface, and when the curtain-type vertical blind is rotated in a direction opposite to the one direction, the front sides of the second shading parts are exposed to the outside, so that a light-absorbing layer forms a blind surface.

[0043] In addition, in the shading fabric for a curtain-type vertical blind according to the sixth embodiment of the present invention, the first magnet and the second magnet or the magnetic body may include at least one of: i) magnetic powder contained in a resin applied to each of the first shading portion and the second shading portion is aligned or magnetized, ii) installed at the lower end of each of the first shading portion and the second shading portion, iii) installed with a vertical gap therebetween, and iv) installed vertically and continuously along each of the first shading portion and the second shading portion.

[0044] When a curtain-type vertical blind is manufactured using the shading fabric for a curtain-type vertical blind according to the present invention as described above, one of two colors can be selected and implemented depending on the rotation direction of the shading part, so that not only can an indoor atmosphere be created in a variety of ways, but it can also avoid causing discomfort or discomfort to others.

[0045] In addition, by manufacturing a curtain-type vertical blind using the shading fabric for a curtain-type vertical blind according to the present invention, the effect of controlling the transmission characteristics of solar heat according to the season can be obtained.

[0046] In addition, when a curtain-type vertical blind is manufactured using the shading fabric for a curtain-type vertical blind according to the present invention, the light-transmitting portion and the light-shielding portion are integrated with each other, and the light-transmitting portion is controlled by the weight of the light-shielding portion, thereby providing the light-transmitting portion with straightness in the downward direction, thereby preventing the light-transmitting portion from waving.

[0047] In addition, when a curtain-type vertical blind is manufactured using the shading fabric for a curtain-type vertical blind according to the present invention, the shape is maintained by preventing the gaps between the shielded blinds from widening, so that no gaps are created between the blinds, preventing the inside from being visible from the outside, and maintaining the neat external shape of the blinds.

[0048] In addition, when a curtain-type vertical blind is manufactured using the shading fabric for a curtain-type vertical blind according to the present invention, when the blind is rotated to adjust the angle, the rotational force is simultaneously transmitted to the lower part of the blind due to the weight of the shading part, so that the lower part of the blind can rotate in the same manner as the upper part of the blind.

[0049] In addition, when a curtain-type vertical blind is manufactured using the shading fabric for a curtain-type vertical blind according to the present invention, the adhesion between adjacent shading parts is significantly improved, so that the interior cannot be seen from the outside when the blind is closed.

[0050] In addition, when a curtain-type vertical blind is manufactured using the shading fabric for a curtain-type vertical blind according to the present invention, the adhesion between adjacent shading parts is significantly improved, so that when the blind is widely opened so that the light-transmitting part is fully exposed, light can be prevented from being transmitted between the shading parts or a gap can be prevented from being created between the shading parts.

[0051] In addition, when a curtain-type vertical blind is manufactured using the shading fabric for a curtain-type vertical blind according to the present invention, the magnet installed at the lower end of the shading fabric acts as a weight that causes the shading fabric to sag downward and spread out, so that the shading fabric does not blow away in the wind and become scattered, and even if it becomes scattered, the lower ends of the shading fabric are attached to each other by magnetic force, so that they can be easily restored to their original state and aligned.

[0052] However, these effects are exemplary and the scope of the present invention is not limited thereby.

[0097] (Example 1)

[0098] First, referring to (a) and (b) of FIG. 6, a shading fabric (1) for a curtain-type vertical blind (100) according to the first embodiment of the present invention is described.

[0099] The material of the shading fabric (1) for a curtain-type vertical blind according to the first embodiment of the present invention is not limited to a fabric woven with a plurality of fibers, and a flexible sheet material such as a non-woven fabric, a knitted fabric, a synthetic resin sheet, a PVC sheet, etc. may be used.

[0100] FIG. 6 (a) is a drawing showing the front side of a shading fabric (1) for a curtain-type vertical blind (100) according to the first embodiment of the present invention, and FIG. 6 (b) is a drawing showing the back side of a shading fabric (1) for a curtain-type vertical blind according to the first embodiment of the present invention; FIG. 7 (a) is a drawing showing the front side of a shading fabric (1) for a curtain-type vertical blind (100) according to a modified example of the first embodiment of the present invention, and FIG. 7 (b) is a drawing showing the back side of a shading fabric (1) for a curtain-type vertical blind according to a modified example of the first embodiment of the present invention.

[0101] A light-shielding fabric (1) for a curtain-type vertical blind (100) according to a first embodiment of the present invention includes: a light-transmitting portion (130); a first light-shielding portion (110) disposed on one side of the light-shielding portion (130) and attached or coupled to the light-shielding portion; and a second light-shielding portion (120) disposed on the other side of the light-shielding portion (130) and attached or coupled to the light-shielding portion. According to the first embodiment of the present invention, for example, as shown in (a) and (b) of FIGS. 6A and 6B, the first and second light-shielding portions (110, 120) may be arranged on the left and right sides of one light-shielding portion (130). Here, the light-shielding portion (130) and the first and second light-shielding portions (110, 120) may be integrally woven, or may be integrally formed by being attached or coupled to each other. As shown in (a) of FIG. 6, the front (110a) of the first shading portion (110) and the back (120b) of the second shading portion (120) are made of the same first color (A) (widely spaced hatched portion), and the back (110b) of the first shading portion (110) and the front (120a) of the second shading portion (120) are made of the same second color (B) (narrowly spaced hatched portion), and the first color (A) may be different from the second color (B).

[0102] In addition, according to a modified example of the first embodiment of the present invention, for example, as illustrated in (a) and (b) of FIG. 7, the light-transmitting portion (130) may be arranged to cover the entire front or rear surface of the first light-shielding portion (110) and the second light-shielding portion (120). That is, the first light-shielding portion (110) and the second light-shielding portion (120) may be arranged at a predetermined interval from each other on one side and the other side of one light-transmitting portion (130), respectively.

[0103] In the shading fabric (1) for a curtain-type vertical blind (100) according to a modified example of the first embodiment, a mesh or mesh-shaped light-transmitting part (130) is arranged on the back of the first shading part (110) and the second shading part (120) so that light and wind can pass through, so that, as shown in (b) of FIG. 7, the colors of the backs of each of the first shading part (110) and the second shading part (120) can be seen from the back through the light-transmitting part (130).

[0104] In the embodiments of (a) and (b) of FIG. 7, the light-transmitting portion (130) and the first and second light-blocking portions (110, 120) may be woven integrally. In addition, the light-transmitting portion (130) may be partially or entirely attached or bonded to each other in the overlapping portion with the first and second light-blocking portions (110, 120). As shown in (a) of FIG. 7, the front (110a) of the first shading portion (110) and the back (120b) of the second shading portion (120) are made of the same first color (A) (widely spaced hatched portion), and the back (110b) of the first shading portion (110) and the front (120a) of the second shading portion (120) are made of the same second color (B) (narrowly spaced hatched portion), and the first color (A) may be different from the second color (B).

[0105] The first shading part (110) of the shading fabric (1) for the curtain-type vertical blind (100) according to the first embodiment of the present invention and its modified examples has different colors on the front side (110a) and the back side (110b), and the first shading part (110) may be formed of a double-woven fabric. For example, in this case, the color of the warp and / or weft yarns arranged on the front side (110a) may be selected as the first color (A), and the color of the warp and / or weft yarns arranged on the back side (110b) may be selected as the second color (B), and the second shading part (120) may also be woven in the same manner as the first shading part (110). In addition, for example, the first shading portion (110) and the second shading portion (120) may be formed as a triple-weave fabric in which warp and / or weft yarns are arranged on the front side, other warp and / or weft yarns are arranged on the back side, and a blackout fiber is arranged in the center between the front and back sides. In this case, for example, the colors of the warp and / or weft yarns arranged on the front side of each of the first shading portion (110) and the second shading portion (120) may be selected to be different from the colors of the warp and / or weft yarns arranged on the back side, thereby woven into a triple-weave fabric.

[0106] In order to manufacture a light-shielding fabric (1) for a curtain-type vertical blind (100) according to the first embodiment of the present invention and its modified examples, the first and second light-shielding parts (110, 120) may be made of a fabric capable of shielding the interior by reducing the circulation of light and wind, and may be made of a fabric such as an opaque fabric, a non-woven fabric, a knitted fabric, a synthetic resin sheet, a PVC sheet, or the like. In addition, the light-transmitting part (130) may be made of a mesh material fabric that allows circulation of air with the exterior space and transmits a certain amount of light while the first and second light-shielding parts (110, 120) block light or wind, but is not limited thereto, and a mesh fabric that is freely bendable and thin may be used. The light-transmitting part (130) may also be made of a material that has translucency that can appropriately reduce the degree of concealment and lighting in the interior in terms of functionality.

[0107] In the case where the shading fabric (1) of the curtain-type vertical blind according to the first embodiment of the present invention and its modified examples is woven integrally with the light-transmitting portion (130) and the first and second light-transmitting portions (110, 120), the light-transmitting portion (130) is woven in a mesh or net shape in a single weaving machine so that light and wind can pass through, and the first and second light-transmitting portions (110, 120) arranged on one side and the other side of the light-transmitting portion (130) and attached or combined with the light-transmitting portion (130) can be woven with a density capable of blocking the passage of light or wind. The front side (110a) of the first light-transmitting portion (110) is woven with a fiber yarn of a first color (A) (e.g., white), and the back side (110b) of the first light-transmitting portion (110) is woven with a fiber yarn of a second color (B) (e.g., beige, sky blue, pink, etc.); The front side (120a) of the second shading part (120) can be woven with fibers of a second color (B) (e.g., beige, sky blue, pink, etc.), and the back side (120b) of the second shading part (120) can be woven with fibers of a first color (A) (e.g., white).

[0108] In addition, the shading fabric (1) of the curtain-type vertical blind according to the first embodiment of the present invention and its modified example can be manufactured by attaching or joining both sides of the light-transmitting portion (130) to the first and second shading portions (110, 120) along the length direction.

[0109] When a curtain-type vertical blind is manufactured using a shading fabric for a curtain-type vertical blind according to the first embodiment of the present invention and a modified example thereof, the light-transmitting portion and the light-shielding portion are integrated with each other, and the light-transmitting portion is controlled by the weight of the light-shielding portion, thereby providing straightness in the downward direction of the light-transmitting portion, thereby preventing the light-transmitting portion from waving.

[0110] In addition, when a curtain-type vertical blind is manufactured using the shading fabric for a curtain-type vertical blind according to the first embodiment of the present invention and its modified examples, the shape of the blinds is maintained by preventing the gaps between the shielded blinds from widening, so that no gaps are created between the blinds, preventing the inside from being visible from the outside, and maintaining the neat external shape of the blinds.

[0111] In addition, when a curtain-type vertical blind is manufactured using the shading fabric for a curtain-type vertical blind according to the first embodiment of the present invention and its modified examples, when the blind is rotated to adjust the angle, the rotational force is simultaneously transmitted to the lower part of the blind due to the weight of the shading part, so that the lower part of the blind can rotate in the same manner as the upper part of the blind.

[0112] (Example 2)

[0113] Next, with reference to FIGS. 8a to 9c, a shade fabric (1) for a curtain-type vertical blind (100) according to a second embodiment of the present invention will be described. When describing the shade fabric (1) according to the second embodiment, descriptions of parts similar to the configuration and operation of the shade fabric (1) according to the first embodiment will be omitted.

[0114] In the first embodiment of the present invention and its modified examples, the light-shielding fabric (1) is made of a first color (A) on the front side (110a) of the first light-shielding portion (110) and a back side (120b) of the second light-shielding portion (120), and is made of a second color (B) on the back side (110b) of the first light-shielding portion (110) and a front side (120a) of the second light-shielding portion (120), whereas in the second embodiment and its modified examples, the light-shielding fabric (1) is made of a first color (A) on the front side (110a) of the first light-shielding portion (110), and is made of a second color (B) on the front side (120a) of the second light-shielding portion (120).

This is a drawing showing.

[0116] As illustrated in (a) and (b) of FIG. 8A, a light-shielding fabric (1) for a curtain-type vertical blind (100) according to a second embodiment of the present invention includes a light-transmitting portion (130); a first light-shielding portion (110) disposed on one side of the light-shielding portion (130) and attached or coupled with the light-shielding portion; and a second light-shielding portion (120) disposed on the other side of the light-shielding portion (130) and attached or coupled with the light-shielding portion. According to the second embodiment of the present invention, for example, as illustrated in FIGS. 8A to 8C, the first and second light-shielding portions (110, 120) may be arranged on the left and right sides of one light-shielding portion (130). Here, the light-shielding portion (130) and the first and second light-shielding portions (110, 120) may be integrally woven, or may be integrally formed by being attached or coupled to each other. As illustrated in (a) of FIG. 8A, the front surface (110a) of the first light-shielding portion (110) may be formed of a first color (A) (widely spaced hatched portion), and the front surface (120a) of the second light-shielding portion (120) may be formed of a second color (B) (narrowly spaced hatched portion) different from the first color (A). In addition, as illustrated in (b) of FIG. 8A, the rear surface (110b) of the first light-shielding portion (110) may be formed of a first color (A) (widely spaced hatched portion), and the rear surface (120b) of the second light-shielding portion (120) may be formed of a second color (B) (narrowly spaced hatched portion). That is, the colors of the front (110a) and the back (110b) of the first shading portion (110) are the same as the first color (A), and the colors of the front (120a) and the back (120b) of the second shading portion (120) can be the same as the second color (B). In this case, the colors of the back (110b) of the first shading portion (110) and the back (120b) of the second shading portion (120) are different from each other.

[0117] In addition, according to a modified example of the second embodiment of the present invention, for example, as illustrated in FIGS. 9A to 9C, the light-transmitting portion (130) may be arranged to cover the entire front or rear surface of the first light-shielding portion (110) and the second light-shielding portion (120). That is, the first light-shielding portion (110) and the second light-shielding portion (120) may be arranged at a predetermined interval from each other on one side and the other side of one light-transmitting portion (130), respectively.

[0118] In the shading fabric (1) for the curtain-type vertical blind (100) according to the modified example of the second embodiment, a mesh or mesh-shaped light-transmitting part (130) is arranged on the back of the first shading part (110) and the second shading part (120) so that light and wind can pass through, so that the colors of the backs of each of the first shading part (110) and the second shading part (120) can be seen from the back through the light-transmitting part (130), as shown in (b) of FIG. 9a, (b) of FIG. 9b, and (b) of FIG. 9c.

[0119] In the embodiments of FIGS. 9A to 9C, the light-transmitting portion (130) and the first and second light-shielding portions (110, 120) may be woven integrally. In addition, the light-transmitting portion (130) may be partially or entirely attached or bonded to the first and second light-shielding portions (110, 120) overlapping with each other.

[0120] In the second embodiment, the first shading part (110) may be woven with a fiber of a first color (A) (e.g., white) on the front side (110a) and the back side (110b), and the second shading part (120) may be woven with a fiber of a second color (B) (e.g., beige, sky blue, pink, etc.) on the front side (120a) and the back side (120b).

[0121] In addition, the back surface (110b) of the first shading portion (110) and the back surface (120b) of the second shading portion (120) of the shading fabric (1) for the curtain-type vertical blind (100) according to the modified example of the second embodiment of the present invention may be made of the same color. In this case, as illustrated in FIG. 8b, the color of the back surface (110b) of the first shading portion (110) and the color of the back surface (120b) of the second shading portion (120) may be the same as the first color (A), which is the color of the front surface (110a) of the first shading portion (110). In addition, as illustrated in FIG. 8c, the color of the back surface (110b) of the first shading portion (110) and the color of the back surface (120b) of the second shading portion (120) may be the same as the second color (B), which is the color of the front surface (120a) of the second shading portion (120). In addition, the color of the back surface (110b) of the first shading portion (110) and the color of the back surface (120b) of the second shading portion (120) may be other colors than the first color (A) and the second color (B).

[0122] The first shading part (110) and the second shading part (120) of the shading fabric (1) for the curtain-type vertical blind (100) according to the second embodiment of the present invention and its modified examples can also be manufactured from a double-weave or triple-weave fabric.

[0123] As shown in Fig. 10, the shading fabric (1) for curtain-type vertical blinds (100) according to the first and second embodiments of the present invention can be attached or coupled to the inner edges of the first and second shading parts (110, 120) on both sides of the light-transmitting part (130). In addition, as shown in Fig. 11, the shading fabric (1) for curtain-type vertical blinds (100) according to the modified example of the first embodiment and the modified example of the second embodiment of the present invention can be attached or coupled to the light-transmitting part (130) starting from a position less than half in the width direction along the length direction of each of the first and second shading parts (110, 120) to the outer edges of the first and second shading parts (110, 120).

[0124] However, when both edges of the light-emitting part (130) are combined or attached to the inner edges of the first and second light-shielding parts (110, 120) as in FIG. 10, or when the light-shielding part (130) is attached from a position less than half in the width direction along the length direction of each of the first and second light-shielding parts (110, 120) to the outer edge as in FIG. 11, that is, when the area (152) where the light-shielding part (130) is bonded (attached or combined) along the length direction to each of the first and second light-shielding parts (110, 120) is 50% or more of the width of the first and second light-shielding parts (110, 120), when the angle of the blind is adjusted to shield for light-shielding or wind-blocking, the light-shielding parts (110, 120) may be separated due to the property of the light-shielding part (130) to spread out. That is, the distance (L1 in Fig. 11) from the two edges (adhesive portions) of the light-emitting portion (130) to the center becomes shorter, so that when the blind is folded, the radius of curvature becomes smaller, and the stiffness of the light-emitting portion (130) to maintain its original shape increases, so that a phenomenon of a gap between the light-shielding portions (110, 120) may occur.

[0125] In order to prevent this phenomenon from occurring, as illustrated in FIGS. 12a and 12b, in the present invention, the light-transmitting portion (130) is arranged in an overlapping form so as to cover the entire surface of the first and second light-shielding portions (110, 120), and the light-transmitting portion (130) can be attached or bonded along the length direction starting from a position (150) that is more than half in the width direction of the front or rear surface of each of the first and second light-shielding portions (110, 120), that is, a position (150) that is at least half in the width direction from the inner edge of each of the first and second light-shielding portions (110, 120), to the outer edge of the first and second light-shielding portions (110, 120). For example, an adhesive line can be formed at a position (150) that is more than half in the width direction of the front or rear surface. Here, the "bonding line" means the point where the adhesion of the light-transmitting portion and the light-shielding portion begins in the width direction of the light-shielding portion, and the bonding line is formed along the longitudinal direction (vertical direction) of the light-shielding portion. As illustrated in Fig. 12b, the area where the light-transmitting portion (130) is bonded (attached or combined) to each of the first and second light-shielding portions (110, 120) along the longitudinal direction is less than 50% of the width of the first and second light-shielding portions (110, 120). The attachment or combination of the light-transmitting portion (130) and the light-shielding portions (110, 120) can be performed using a known adhesive, and a detailed description thereof is omitted.

[0126] The above light-transmitting portion (130) may be coupled or attached longitudinally from a position greater than halfway from the front or rear portion of the first and second light-blocking portions (110, 120) to the outer edges. For example, as illustrated in FIG. 12b, the area where the light-transmitting portion (130) is coupled or attached longitudinally from the rear portions of each of the first and second light-blocking portions (110, 120) may be less than 50% of the width of the first and second light-blocking portions (110, 120). In addition, as illustrated in FIG. 13, the outer edges of both sides of the light-transmitting portion (130) may be coupled or attached to the outer edges of the rear portions of the first and second light-blocking portions (110, 120). In the case of Fig. 13, an adhesion line (150) may be formed on the outer edge of the first and second light-shielding portions (110, 120) with the outer edge of the light-transmitting portion (130). In this case, the light-transmitting portion (130) is attached or bonded only to the outer edge of the first and second light-shielding portions (110, 120), and the light-transmitting portion (130) is not bonded or bonded to the light-shielding portion (110, 120) in the remaining area in the width direction of the first and second light-shielding portions (110, 120).

[0127] By this configuration, when the light-transmitting part (130) is coupled between the first light-shielding part (110) and the second light-shielding part (120), as shown in FIG. 12b or FIG. 13, the light-transmitting part (130) is coupled or attached to the light-shielding part (110, 120) at a position that starts from more than half of the width of the light-shielding part (110, 120) and is attached or coupled to the outer edge of the light-shielding part (110, 120), that is, when the area (152) where the light-transmitting part (130) is attached or coupled to each of the light-shielding parts (110, 120) is less than 50% of the width of the light-shielding part (110, 120), as shown in FIG. 11, the position where the light-transmitting part (130) starts to be coupled or attached to the light-shielding part (110, 120) is the light-shielding part (110, 120). Compared to the case where the width is less than half of the width of the light-emitting portion (120), the distance (L2) from the bonding point to the center of the light-emitting portion (130) can be secured significantly. That is, the distance (L2) from the bonding line (150) to the center of the light-emitting portion (130) can be secured sufficiently.

[0128] Fig. 12c is a partially enlarged view showing the attachment or bonding configuration of the light-transmitting portion to the light-shielding portion in the light-shielding fabric of Fig. 12b, Fig. 12d is a schematic drawing showing a state viewed from above when the light-shielding portions on both sides of the light-shielding fabric of Fig. 12b are arranged side by side with a predetermined interval between them, and Fig. 12e is a schematic drawing showing a state viewed from above when the light-shielding fabrics of Fig. 12d are arranged adjacently and fixed. For example, as illustrated in Fig. 12c, the adhesive (151) that adheres the light-transmitting portion (130) to the light-shielding portions (120, 130) exists only in an adhesive area (152) less than 50% of the width of the light-shielding portions (110, 120). Accordingly, when using a curtain-type vertical blind (100) manufactured using a light-shielding fabric according to an embodiment of the present invention, when the light-shielding parts on both sides are arranged side by side with a predetermined interval as shown in FIG. 12d, the light-transmitting part (130) can be freely separated from the outer surface of the light-shielding parts (110, 120) in the area where the adhesive (151) is not applied, so that even if the light-transmitting part (130) is curved in a U-shape, the light-transmitting part (130) naturally spreads out, thereby reducing the stiffness. Therefore, when the light-shielding fabrics are arranged adjacently as shown in FIG. 12e, the adjacent light-transmitting parts come into contact with each other, so that no gap is created between the adjacent light-transmitting parts.

[0129] According to the above configuration, when the curtain-type vertical blind (1) is folded, even if the light-transmitting portion (130) located between the first light-shielding portion (110) and the second light-shielding portion (120) is curved in a U shape, the distance (L2) from the edges (adhesive portions) on both sides of the light-transmitting portion (130) to the center increases, so that when the blind is folded, the radius of curvature increases, and the stiffness of the light-transmitting portion (130) to maintain its original shape decreases, so that, as illustrated in FIG. 14, the first and second light-shielding portions (110, 120) do not gap together, and the light-shielding portions (110, 120) can be maintained in close contact with each other.

[0130] In the first embodiment, the second embodiment, and their modifications of the present invention, the light-transmitting portion (130) and the first and second light-shielding portions (110, 120) can be attached by heat-treating hot melt and then pressing, or by applying a fabric adhesive and then pressing, and the first and second light-shielding portions (110, 120) and the light-transmitting portion can be attached by sewing or ultrasonic welding, or can be attached or combined by other known attachment methods, and a detailed description thereof is omitted.

[0131] Curtain-type vertical blinds according to the first embodiment, the second embodiment and their modifications of the present invention can be manufactured by continuously joining adjacent shading fabric sections.

[0132] On one side of the upper guide rail (300) that guides the horizontal movement of the curtain-type vertical blind (100) according to the first embodiment, the second embodiment and a modified example thereof of the present invention, adjusting means (not shown) that adjust the horizontal movement of the curtain-type vertical blind and the left and right rotation angle of the blinds with respect to the vertical axis may be installed.

[0133] In addition, in the shading fabric (1) of the curtain-type vertical blind (100) according to the first embodiment, the second embodiment, and their modifications of the present invention, additional weights (not shown) may be installed at the lower end of the first shading portion (110) and the lower end of the second shading portion (120), and the weights may be magnetically attached to each other. In addition, a wick (not shown) may be additionally attached to the lower end of the first shading portion (110) and the lower end of the second shading portion (120) to add weight. With this configuration, the lower ends of the blinds can be prevented from spreading apart from each other, and can be neatly stretched downward.

[0134] In the curtain-type vertical blind (100) according to the first embodiment, the second embodiment, and their modifications of the present invention, the back surface (110b) of the first shading part (110) of one section (10) of a plurality of shading fabric sections (10, 20, 30, ... n) and the back surface (120b) of the second shading part (120) of the other section (20) are joined in a state of contact, so that the front surface (110a) of the first shading part (110) of one shading fabric section (10) and the front surface (120a) of the second shading part (120) of the other shading fabric section (20) become blind surfaces visible from the outside.

[0135] By this configuration, when the curtain-type vertical blind (100) is spread out horizontally (state of FIG. 21), when the first shading parts (110) and the second shading parts (120) of the plurality of shading fabric sections (10, 20, 30, ... n) are rotated in one direction about the vertical axis, the front surface (110a) of the first shading parts (110) is exposed to the indoor side to form a blind surface of the first color (A) (widely spaced hatched part) (state of FIG. 22), and the second color (B) (narrowly spaced hatched part) of the front surface (120a) of the second shading parts (120) can be exposed to the outdoor side.

[0136] Conversely, when the first shading portions (110) and the second shading portions (120) of the plurality of shading fabric sections (10, 20, 30, ... n) are rotated in the opposite direction to the one direction about the vertical axis, the front surface (120a) of the second shading portions (120) is exposed to the indoor side to form a blind surface of the second color (B) (narrowly spaced hatched portion) (state of FIG. 23), and the first color (A) (widely spaced hatched portion) of the front surface (110a) of the first shading portions (110) can be exposed to the outdoor side.

[0137] Accordingly, in the curtain-type vertical blind (100) manufactured using the shading fabric for the curtain-type vertical blind (100) according to the present invention, one of two colors (A or B) can be selected and implemented depending on the rotation direction of the shading part, so that not only can the indoor atmosphere be created in a variety of ways, but also it can avoid causing discomfort or discomfort to others. For example, when the first color (A) of the front surface (110a) of the first shading part (110) is set to white and the second color (B) of the front surface (120a) of the second shading part (120) is set to beige, the indoor side can be implemented with the beige color of the second color (B) to create a warm and calm indoor atmosphere, and the outdoor side can be implemented with the white color of the first color (A) to express a bright window appearance. In addition, in the case of a consumer who prefers a color with a strong personality, if the first color (A) of the front (110a) of the first shading part (110) is white and the second color (B) of the front (120a) of the second shading part (120) is pink or sky blue, the indoor side is implemented with the pink or sky blue of the second color (B) to create a unique indoor atmosphere, and the outdoor side is implemented with the white of the first color (A) to express a bright window appearance, thereby bringing out the personality of the consumer while not damaging the overall view of the apartment in a multi-purpose building such as an apartment and not causing a sense of discomfort or discomfort to others.

[0138] Meanwhile, according to a modified example of the first and second embodiments of the present invention, a shading fabric for a curtain-type vertical blind comprises: a light-transmitting portion (130) through which light can pass; a first shading portion (110) disposed on one side of the light-transmitting portion (130) and attached or coupled to the light-transmitting portion; And a second light-shielding portion (120) disposed on the other side of the light-shielding portion (130) and attached or coupled to the light-shielding portion, wherein the light-shielding portion (130) is arranged to cover the entire surface of the front or rear of the first and second light-shielding portions (110, 120), and the light-shielding portion (130) is attached or coupled to the first and second light-shielding portions (110, 120) at a point where the light-shielding portion (130) exceeds half of the width of the front or rear of each of the first and second light-shielding portions (110, 120), and is attached or coupled to the outer edge of the first and second light-shielding portions (110, 120), and the front (110a) of the first light-shielding portion (110), the rear (110b) of the first light-shielding portion (110), the front (120a) of the second light-shielding portion (120), and the second The back side (120b) of the shading part (120) can be made of the same color.

[0139] In the shading fabric for curtain-type vertical blinds according to the modified examples of the first and second embodiments as described above, the adhesive (151) that adheres the light-transmitting portion (130) to the light-shielding portions (120, 130) exists only in an adhesive area (152) that is less than 50% of the width of the light-shielding portions (110, 120). Accordingly, when using the curtain-type vertical blind (100) manufactured using the shading fabric according to the modified examples of the first and second embodiments, when the two light-shielding portions are adjusted to be arranged side by side with a predetermined interval, the light-transmitting portion (130) can be freely separated from the outer surface of the light-shielding portions (110, 120) in the area where the adhesive (151) is not applied, so that even if the light-transmitting portion (130) is bent into a U-shape, the light-transmitting portion (130) naturally opens up, thereby reducing the stiffness. Therefore, when shading fabrics are arranged adjacently, adjacent light-transmitting portions come into contact with each other, so that no gap is created between adjacent light-transmitting portions.

[0140] (Example 3)

[0141] Next, a shade fabric (1) for a curtain-type vertical blind (100) according to a third embodiment of the present invention will be described. When describing the shade fabric (1) according to the third embodiment, descriptions of similar parts to the configuration and operation of the shade fabric (1) according to the first embodiment, the second embodiment, and modifications thereof will be omitted.

[0142] In the first embodiment, the second embodiment and their modifications of the present invention, the front and back surfaces of the first shading portion (110) and the second shading portion (110) of the shading fabric (1) are made of the first color (A) and / or the second color (B), whereas in the third embodiment and its modifications, a light reflecting layer is formed on the front surface of the first shading portion (110) of the shading fabric (1) and a light absorbing layer is formed on the front surface of the second shading portion (120).

[0143] Referring to FIGS. 8a to 9c, a third embodiment of the present invention and a modified example thereof will be described.

[0144] (a) of FIG. 8a is a drawing showing the front side of the shading fabric (1) for the curtain-type vertical blind (100) of the present invention, and (b) of FIG. 8a is a drawing showing the back side of the shading fabric (1) for the curtain-type vertical blind of the present invention.

[0145] As illustrated in (a) and (b) of FIG. 8A, a light-shielding fabric (1) for a curtain-type vertical blind (100) according to a third embodiment of the present invention includes a light-transmitting portion (130); a first light-shielding portion (110) disposed on one side of the light-shielding portion (130) and attached or coupled to the light-shielding portion; and a second light-shielding portion (120) disposed on the other side of the light-shielding portion (130) and attached or coupled to the light-shielding portion. A light-reflecting layer may be formed on the front surface (110a) (widely spaced hatched portion) of the first light-shielding portion (110) illustrated in (a) of FIG. 8A, and a light-absorbing layer may be formed on the front surface (120a) (narrowly spaced hatched portion) of the second light-shielding portion (120). For example, the light reflecting layer may have a smoother surface as more light is reflected, and the light absorbing layer may have a relatively rougher surface compared to the light reflecting layer.

[0146] In addition, according to a modified example of the third embodiment of the present invention, for example, as shown in (b) of FIG. 9a, (b) of FIG. 9b, and (b) of FIG. 9c, the light-transmitting portion (130) may be arranged to cover the entire surface of the front or back of the first light-shielding portion (110) and the second light-shielding portion (120). That is, the first light-shielding portion (110) and the second light-shielding portion (120) may be arranged at a predetermined interval from each other on one side and the other side of one light-transmitting portion (130), respectively.

[0147] In addition, according to a modified example of the third embodiment of the present invention, a separate second shading part (120) and a separate first shading part (10) can be additionally attached to the inner or outer surface of each of the second shading part (120) and the first shading part (110) on the far left and right sides of the curtain-type vertical blind (100).

[0148] Meanwhile, a shading fabric (1) for a curtain-type vertical blind (100) according to a modified example of the third embodiment includes a light-transmitting portion (130); a first shading portion (110) disposed on one side of the light-transmitting portion (130) and attached or coupled with the light-transmitting portion; and a second shading portion (120) disposed on the other side of the light-transmitting portion (130) and attached or coupled with the light-transmitting portion. The first shading portion (110) may be made of a material that reflects light well, and the second shading portion (120) may be made of a material that absorbs light well. The material that reflects light well or the material that absorbs light well may utilize a known technology, and a detailed description thereof will be omitted.

[0149] In the curtain-type vertical blind (100) according to the third embodiment of the present invention and its modified examples as described above, the back surface (110b) of the first shading part (110) of one section (10) of a plurality of shading fabric sections (10, 20, 30, ... n) and the back surface (120b) of the second shading part (120) of the other section (20) are joined in a state of contact, so that the front surface (110a) of the first shading part (110) of one shading fabric section (10) and the front surface (120a) of the second shading part (120) of the other shading fabric section (20) become blind surfaces visible from the outside. Here, a light reflective layer may be formed on the front surface (110a) of the first shading parts (110), and a light absorbing layer may be formed on the front surface (120a) of the second shading parts (120).

[0150] By this configuration, when the curtain-type vertical blind (100) is unfolded (state of FIG. 21), when the first shading parts (110) and the second shading parts (120) of the plurality of shading fabric sections (10, 20, 30, ... n) are rotated in one direction about the vertical axis, the front surface (110a) (widely spaced hatched part) of the first shading parts (110) is exposed to the interior side, so that the light reflecting layer or the light reflecting material member forms the blind surface (state of FIG. 22), and the light absorbing layer or the light absorbing material member of the front surface (120a) (narrowly spaced hatched part) of the second shading parts (120) can be exposed to the exterior side.

[0151] Conversely, when the first shading portions (110) and the second shading portions (120) of the plurality of shading fabric sections (10, 20, 30,... n) are rotated in the opposite direction to the one direction about the vertical axis, the front surface (120a) (narrowly spaced hatched portion) of the second shading portions (120) is exposed to the indoor side, so that the light-absorbing layer or the light-absorbing material member forms a blind surface (state of FIG. 23), and the light-reflecting layer or the light-reflecting material member of the front surface (110a) (widely spaced hatched portion) of the first shading portions (110) can be exposed to the outdoor side.

[0152] Accordingly, in a curtain-type vertical blind (100) manufactured using a shading fabric for a curtain-type vertical blind (100) according to the present invention, one of two functions (light reflection function or light absorption function) can be selected and implemented depending on the rotation direction of the shading part, thereby controlling the transmission characteristics of solar heat according to the season.

[0153] For example, if the front surface (110a) of the first shading part (110) is configured as a light reflective layer or the first shading part (110) is configured as a light reflective material and the front surface (120a) of the second shading part (120) is configured as a light absorbing layer or the second shading part (120) is configured as a light absorbing material, in the summer, the blinds are adjusted so that the front surface (110a) of the first shading part (110) (light reflective layer or light reflective material member) faces the outside, thereby reducing the amount of solar heat transferred indoors and suppressing an increase in indoor temperature, and in the winter, the blinds are adjusted so that the front surface (120a) of the second shading part (120) (light absorbing layer or light absorbing material member) faces the outside, thereby increasing the amount of solar heat transferred indoors and promoting an increase in indoor temperature, thereby allowing the solar heat transfer characteristics to be controlled seasonally using a single curtain-type vertical blind.

[0154] In addition, in a curtain-type vertical blind (100) manufactured using a shading fabric for a curtain-type vertical blind according to a modified example of the third embodiment of the present invention, one of two materials can be selected and implemented depending on the rotation direction of the shading part, so that different indoor atmospheres can be created depending on the texture of the material.

[0155] The method of attaching the light-transmitting portion and the light-shielding portion in the shading fabric for curtain-type vertical blinds according to the third embodiment of the present invention and its modified examples can be applied in the same manner as the method of attaching the light-transmitting portion and the light-shielding portion in the first embodiment, the second embodiment and its modified examples.

[0156] In addition, when manufacturing a curtain-type vertical blind using a shading fabric for a curtain-type vertical blind according to the third embodiment of the present invention and its modified examples, the weights installed at the bottom of the first and second shading sections of the shading fabric (1) can be applied equally to the third embodiment and its modified examples.

[0157] (Example 4)

[0158] Next, with reference to FIGS. 15 and 19, a fourth embodiment of a method for manufacturing a curtain-type vertical blind (100) according to the first embodiment, the second embodiment, and modifications thereof of the present invention will be described. First, a shading fabric (1) according to the first embodiment, the second embodiment, and modifications thereof of the present invention is cut into a plurality of shading fabric sections (10, 20, 30, 40, 50, 60, ... n) having a predetermined length (a length corresponding to the vertical height of a window or entrance). As described above, the plurality of shading fabric sections (10, 20, 30, 40, 50, 60, ... n) cut are arranged so that the back surface (110b) of the first shading portion (110) of one section (10) and the back surface (120b) of the second shading portion (120) of another section (20) are in contact with each other, thereby arranging adjacent shading fabric sections (10, 20, 30, 40, 50, 60, ... n). The plurality of shade fabric sections (10, 20, 30, ... n) arranged in this manner are fixed together by fixing the upper end of the first shade part (110) of one section (10) and the upper end of the second shade part (120) of another section (20) by fixing means (200) to adjacent shade fabric sections (10, 20, 30, 40, 50, 60, ... n).

[0159] As illustrated in FIGS. 15, 17, and 19, in the manufacturing method of the curtain-type vertical blind (100) according to the fourth embodiment of the present invention, adjacent shading fabric sections (10, 20, 30, 40, 50, 60, ... n) are fixed together, so that the shading parts (110, 120) of the adjacent shading fabric sections overlap in the center, but only the first shading part (110) or the second shading part (120) is arranged at the outermost sides on the left and right. Accordingly, the amount of light transmitted through the shading parts (110, 120) in the center and the amount of light transmitted through the first shading part (110) or the second shading part (120) at the far left and right are different, and a phenomenon may occur in which the amount of light transmitted through the blind becomes uneven depending on the location. In order to prevent this phenomenon from occurring, in the manufacturing method of the curtain-type vertical blind (100) according to the modified example of the fourth embodiment of the present invention, a separate second shading part (120) and a separate first shading part (10) can be additionally attached to the inner or outer surface of each of the second shading parts (120) and the first shading parts (110) on the far left and right sides and connected. FIG. 17 illustrates additionally attaching and connecting a separate second shading part (120) and a separate first shading part (10) to the inner surface of each of the second shading parts (120) and the first shading parts (110) on the far left and right sides of the curtain-type vertical blind (100).

[0160] Additionally, the upper ends of the first shading portion (110) and the upper ends of the second shading portions (120) of adjacent shading fabric sections (10, 20, 30, 40, 50, 60, ... n) can be fixed in various ways.

[0161] For example, one or more through holes (160) are perforated at the upper end of the first shading portion (110) and the upper end of the second shading portion (120) of the shading fabric sections using an awl or a punching machine. Then, the fixing pin (210) of the detachable fixing means (200) is inserted and fixed into the fixing hole (230) while the upper end of the first shading portion (110) and the upper end of the second shading portion (120) are arranged to be in contact with each other, so that the first shading portion (110) and the second shading portion (120) can be connected. FIGS. 16A and 16B illustrate fixing means (200) that can be used in the manufacture of curtain-type vertical blinds according to the first embodiment, the second embodiment, and modifications thereof of the present invention. A joining groove (220) that can be detachably joined to the upper guide rail (300) may be formed at the upper end of the above-described fixing means (200). The method of joining the fixing means (200) of the first shading part (110) and the second shading part (120) to the upper guide rail (300) may utilize a known technology, and a member in the form of a ring or clip may be used as the fixing means.

[0162] In addition, the lower ends of the first shading portion (110) and the lower ends of the second shading portions (120) of the adjacent shading fabric sections (10, 20, 30, ... n) may be additionally connected to each other by additional connecting members, such as, for example, a detachable Velcro tape, and weights (not shown) may be additionally installed on the lower ends of the first shading portion (110) and the lower ends of the second shading portions (120) of the shading fabric sections (10, 20, 30, ... n), and the weights may be magnetically attached to each other. In addition, a wick (not shown) may be additionally attached to the lower ends of the first shading portion (110) and the lower ends of the second shading portions (120) to add weight. With this configuration, the lower ends of the blinds can be prevented from spreading apart from each other and can be neatly stretched downward.

[0163] The curtain-type vertical blind (100) according to the third embodiment of the present invention and its modifications can also be manufactured by continuously joining light-blocking fabric sections, similarly to the curtain-type vertical blind (100) according to the first embodiment, the second embodiment and its modifications, and the manufacturing process can be applied in the same manner, so a detailed description thereof is omitted.

[0164] (Example 5)

[0165] Next, with reference to FIGS. 24 to 32, a shade fabric (1) for a curtain-type vertical blind (100) according to a fifth embodiment of the present invention will be described. When describing the shade fabric (1) according to the fifth embodiment, descriptions of similar parts to the configuration and operation of the shade fabric (1) according to the first embodiment, the second embodiment, and modifications thereof will be omitted.

[0166] The fifth embodiment of the present invention is similar to the first embodiment, the second embodiment, and variations thereof in that the colors of the front and back surfaces of the first and second shading portions of the shading fabric (1) are composed of the first color (A) and / or the second color (B). However, the fifth embodiment of the present invention is different from the first embodiment, the second embodiment, and variations thereof in that the first magnet (M1) is installed in the first shading portion (110), and the second magnet (M2) or a magnetic body is installed in the second shading portion (120).

[0167] In the fifth embodiment of the present invention, in the shading fabric (1) for a curtain-type vertical blind in which a first shading part (110) and a second shading part (120) are arranged on one side and the other side of a light-transmitting part (130), a first magnet (M1) may be installed in the first shading part (110), and a second magnet (M2) or a magnetic body may be installed in the second shading part (120).

[0168] For example, in the shading fabric (1) of the fifth embodiment, in which the shading parts (110, 120) are respectively adhered or bonded to one side and the other side of the light-transmitting part (130) as illustrated in FIG. 24, the first magnet (M1) and the second magnet (M2) may be aligned or magnetized by magnetic powder contained in the resin applied to the first shading part (110) and the second shading part (120), respectively. In this case, the resin may perform the function of an adhesive including an adhesive component. The first magnet (M1) may be aligned in the same direction as the same polarity of the magnetic powder (114) contained in the resin (113) applied to the first shading part (110). Preferably, the first magnet (M1) may be aligned or magnetized so as to be arranged in a direction perpendicular to the surface of the shading fabric (1). For example, a mixture of magnet powder (114) and resin (113) such as epoxy, polyethylene, polyurethane, polymethyl methacrylate (PMMA), and polyethylene terephthalate (PET) may be applied to the first light-shielding portion (110) to be aligned or magnetized. Both the magnet powder and the resin may be transparent, both may be opaque, or a mixture of opaque magnet powder and transparent resin may be used. The same applies to the second magnet (M2) installed in the second light-shielding portion (120). In this case, it is preferable that the resin and magnet powder be applied to the rear surface (110b) of the first light-shielding portion (110) and the rear surface (120b) of the second light-shielding portion (120). In the embodiment illustrated in FIG. 24, the front surface (110a) of the first shading portion (110) and the back surface (120b) of the second shading portion (120) are made of a first color (A), and the back surface (110b) of the first shading portion (110) and the front surface (120a) of the second shading portion (120) are made of a second color (B).

[0169] In the shade fabric (1) for the curtain-type vertical blind (100) according to the fifth embodiment of the present invention, the second magnet (M2) installed in the second shade part (120) has a polarity that is arranged in the opposite direction to the first magnet (M1) installed in the first shade part (110). For example, when the shade fabric (1) is spread out flat, if the first magnet (M1) has a N pole facing the front side and a S pole facing the rear side of the shade fabric (1), the second magnet (M2) may have a S pole facing the front side and a N pole facing the rear side of the shade fabric (1). If necessary, a pigment may be added to the transparent resin so that the colors of the first magnet (M1) and the second magnet (M2) have a color desired by the user. Additionally, if necessary, a pigment having the same color as the first and second light-shielding portions (110, 120) may be added to the transparent resin so that the first magnet (M1) and the second magnet (M2) have the same color as the first and second light-shielding portions (110, 120).

[0170] In addition, for example, as illustrated in FIG. 25, a light-transmitting portion (130) through which light can pass; a first light-shielding portion (110) disposed on one side of the light-transmitting portion (130) and attached or coupled to the light-transmitting portion; And a second light-shielding part (120) disposed on the other side of the light-shielding part (130) and attached or coupled to the light-shielding part, wherein the front side (110a) of the first light-shielding part (110) and the back side (120b) of the second light-shielding part (120) are made of a first color (A), and the back side (110b) of the first light-shielding part (110) and the front side (120a) of the second light-shielding part (120) are made of a second color (B), in the light-shielding fabric (1), the first magnet (M1) and the second magnet (M2) may be magnet powders that are aligned or magnetized and contained in a resin applied to the first light-shielding part (110) and the second light-shielding part (120), respectively. FIG. 25 (a) shows the front side of the light-shielding fabric (1), and FIG. 25 (b) shows the back side of the light-shielding fabric (1). As illustrated in (b) of Fig. 25, the light-transmitting portion (130) may be arranged to cover the entire front or rear surface of the first light-shielding portion (110) and the second light-shielding portion (120). In this case, the resin may function as an adhesive containing an adhesive component, and the resin may function to adhere the light-transmitting portion (130) to the first and second light-shielding portions (110, 120).

[0171] In addition, for example, as shown in FIGS. 26 and 27, in the shading fabric (1) in which the shading parts (110, 120) are respectively adhered or bonded to both edges of the light-transmitting part (130), the first magnet (M1) and the second magnet (M2) may be film-type magnets made of a magnetic material. FIG. 26 illustrates that the film-type magnets are installed vertically and continuously on each of the first shading part (110) and the second shading part (120), and FIG. 27 illustrates that the film-type magnets are installed vertically and spaced apart on each of the first shading part (110) and the second shading part (120). In FIGS. 26 and 27, the film-type magnets are shown as being arranged on the inner edges of each of the first shading portion (110) and the second shading portion (120), but the film-type magnets may also be arranged on the outer edges or centers of each of the first shading portion (110) and the second shading portion (120). Here, if necessary, a magnetic body may be installed in the second shading portion (120) instead of the film-type second magnet (M2).

[0172] In the embodiment of FIG. 26 or FIG. 27, the shading fabric (1) for a curtain-type vertical blind according to the present invention may be configured by partially overlapping a first shading part (110) and joining it to one edge of a light-transmitting part (130), and installing a first magnet (M1) in the form of a film on the back surface of the light-transmitting part (130) and the first shading part (110) or on the inner surface when bent in a U-shape, and partially overlapping a second shading part (120) and joining it to the other edge of the light-transmitting part (130), and installing a second magnet (M2) in the form of a film or a film-type magnetic body on the back surface of the light-transmitting part (130) and the second shading part (120) or on the inner surface when bent in a U-shape. The adhesion between the light-emitting part (130) and the first light-shielding part (110) and the adhesion between the light-emitting part (130) and the second light-shielding part (120) may be accomplished using an adhesive, but may also be accomplished by ultrasonic or high-frequency welding. Here, one of the first magnet (M1) and the second magnet (M2) may be a magnetic material. The first magnet (M1) and the second magnet (M2) or the magnetic material may be installed in a long, continuous manner in the longitudinal direction of the light-shielding fabric (1), as illustrated in FIG. 26, and, if necessary, the first magnet (M1) and the second magnet (M2) or the magnetic material may be installed with a vertical gap in the longitudinal direction of the light-shielding fabric (1), as illustrated in FIG. 27. Here, the first and second magnets (M1, M2) can be installed on the front (110a, 120a) or back (110b, 120b) of the light-shielding fabric (1).

[0173] In addition, in the embodiment of FIG. 26 or FIG. 27, if necessary, the light-shielding fabric (1) according to the present invention may be configured by partially overlapping the first light-shielding part (110) on one edge of the light-transmitting part (130) and bonding the first magnet (M1) in the form of a film between the light-transmitting part (130) and the first light-shielding part (110), and by partially overlapping the second light-shielding part (120) on the other edge of the light-transmitting part (130) and bonding the second magnet (M2) in the form of a film or a magnetic material in the form of a film between the light-transmitting part (130) and the second light-shielding part (120).

[0174] In addition, for example, as shown in FIGS. 28 and 29, in the shade fabric (1) of the fifth embodiment, the first magnet (M1) and the second magnet (M2) may be installed in a circular shape at the bottom of the first shade part (110) and the second shade part (120), respectively. In this way, when the circular first magnet (M1) and second magnet (M2) are attached to the bottom of the shade fabric (1), the first magnet (M1) and the second magnet (M2) may also serve as a weight to cause the shade fabric (1) of the blind to sag downward and spread out. Even in this case, as illustrated in FIGS. 28 and 29, it is preferable that the first magnet (M1) and the second magnet (M2) be installed so as to be biased toward the light-transmitting portion (130) from the front surface (110a) of the first light-shielding portion (110) and the front surface (120a) of the second light-shielding portion (120). In addition, the first magnet (M1) and the second magnet (M2) or the magnetic body may be wrapped or coated with a molten material that can be melted by ultrasonic waves or high frequency, and the molten material may be attached to the first light-shielding portion (110) and the second light-shielding portion (120) by a fusion method, respectively, by ultrasonic waves or high frequency.

[0175] In addition, for example, as shown in FIG. 30, in the shade fabric (1) of the fifth embodiment, the first magnet (M1) and the second magnet (M2) may be installed in a horizontal band shape at the lower ends of the first shade part (110) and the second shade part (120), respectively.

[0176] In addition, in a modified example of the fifth embodiment, a metal weight may be installed instead of the first magnet (M1) and the second magnet (M2) in the shape of a circle or a band installed at the lower end of each of the first shading part (110) and the second shading part (120) illustrated in FIGS. 28 to 30. In this case, the weight may also serve to cause the shading fabric (1) of the blind to sag downward and spread out. In addition, as illustrated in FIG. 30, a reinforcing part (170) may be formed at the upper end of the shading fabric (1) for coupling the fixing means (200), and a through hole (160) may be perforated in the reinforcing part (170) to form the shading fabric (1) according to the fifth embodiment of the present invention.

[0177] Next, with reference to FIG. 32, a vertical blind (100) manufactured using a shading fabric (1) for a curtain-type vertical blind according to the fifth embodiment of the present invention illustrated in FIGS. 24 to 30 will be described as an example.

[0178] Referring to FIG. 32, a vertical blind (100) according to the present invention comprises an upper guide rail (300) installed horizontally on a window frame or a wall or ceiling above the window frame, a plurality of runners (not shown) installed on the upper guide rail (300) so as to be able to move left and right, a plurality of fixing means (200) installed on the plurality of runners and holding together the upper ends of a first shading part (110) of a shading fabric (1) and a second shading part (120) of an adjacent shading fabric (1), and a plurality of shading fabrics (1) according to the present invention coupled to the fixing means. In addition, adjustment means (not shown) for moving the runners to one side and rotating the shading fabrics (1), etc. may be installed, but since such adjustment means are known techniques, illustration and description thereof are omitted herein.

[0179] According to the shading fabric (1) for a curtain-type vertical blind according to the fifth embodiment of the present invention and its modifications described above, and the vertical blind (100) manufactured using the same, when the light-transmitting portion (130) is spread out so that it is widely exposed to the front, the first magnet (M1) installed in the first shading portion (110) and the second magnet (M2) installed in the second shading portion (120) of the shading fabric (1) adjacent to it can attract and close the adjacent first shading portion (110) and second shading portion (120), thereby minimizing the gap between the first shading portion (110) and second shading portion (120), so that the adhesion between adjacent shading portions is significantly improved, and when the blind is closed, the interior cannot be seen from the outside. In addition, when a curtain-type vertical blind is manufactured using the shading fabric for a curtain-type vertical blind according to the fifth embodiment of the present invention, the adhesion between adjacent shading portions is significantly improved, so that when the blind is widely spread out, light can be prevented from being transmitted between adjacent shading portions or a gap can be prevented from being formed between the shading portions. In addition, when a curtain-type vertical blind is manufactured using the shading fabric for a curtain-type vertical blind according to the fifth embodiment of the present invention, the magnet installed at the lower end of the shading fabric acts as a weight that causes the shading fabric to sag downward and spread out, so that the shading fabric is not blown away by the wind and is not disturbed, and even if it is disturbed, the lower ends of the shading fabric are closely adhered to each other by the magnetic force, so that they can be easily restored to their original state and aligned.

[0180] (Example 6)

[0181] Next, with reference to FIGS. 33 to 37, a shade fabric (1) for a curtain-type vertical blind (100) according to a sixth embodiment of the present invention will be described. When describing the shade fabric (1) according to the sixth embodiment, descriptions of similar parts to the configuration and operation of the shade fabric (1) according to the first embodiment, the second embodiment, and the fifth embodiment and their modifications will be omitted.

[0182] In the sixth embodiment of the present invention, a first magnet (M1) is installed in the first shading portion (110), and a second magnet (M2) or a magnetic body is installed in the second shading portion (120), which is different from the first and second embodiments. In addition, in the sixth embodiment, the front surfaces (110a, 120a) and the back surfaces (110b, 120b) of the first shading portion (110) and the second shading portion (120) are all made of the same color, which is different from the fifth embodiment.

[0183] According to a sixth embodiment of the present invention, in a shading fabric for a curtain-type vertical blind, the shading fabric (1) includes a light-transmitting portion (130); a first shading portion (110) disposed on one side of the light-transmitting portion (130) and attached or coupled to the light-transmitting portion; and a second shading portion (120) disposed on the other side of the light-transmitting portion (130) and attached or coupled to the light-transmitting portion. In addition, a first magnet (M1) may be installed on the first shading portion (110), and a second magnet (M1) or a magnetic body may be installed on the second shading portion (120).

[0184] For example, as illustrated in Fig. 33, in the shading fabric (1) for a curtain-type vertical blind according to the sixth embodiment, the first magnet (M1) and the second magnet (M2) may be aligned or magnetized magnetic powder contained in a resin applied to the first shading portion (110) and the second shading portion (120), respectively. In this case, the resin may perform the function of an adhesive including an adhesive component.

[0185] In addition, for example, as illustrated in FIGS. 34 and 35, in the shading fabric (1) for a curtain-type vertical blind according to the sixth embodiment, the first magnet (M1) and the second magnet (M2) may be film-type magnets made of a magnetic material. FIG. 34 illustrates that the film-type magnets are installed vertically and continuously on each of the first shading portion (110) and the second shading portion (120), and FIG. 35 illustrates that the film-type magnets are installed vertically and spaced apart on each of the first shading portion (110) and the second shading portion (120). In FIGS. 34 and 35, the film-type magnets are shown arranged on the inner edges of each of the first shading portion (110) and the second shading portion (120), but the film-type magnets may also be arranged on the outer edges or centers of each of the first shading portion (110) and the second shading portion (120). Here, if necessary, a magnetic body may be installed in the second shading portion (120) instead of the film-type second magnet (M2).

[0186] In addition, for example, as illustrated in FIG. 36, in the shading fabric (1) for a curtain-type vertical blind according to the sixth embodiment, the first magnet (M1) and the second magnet (M2) may be installed in a circular shape at the bottom of the first shading part (110) and the second shading part (120), respectively. In this way, when the circular first magnet (M1) and second magnet (M2) are attached to the bottom of the shading fabric (1), the first magnet (M1) and the second magnet (M2) may also serve as a weight to cause the shading fabric (1) of the blind to sag downward and spread out.

[0187] In addition, for example, as shown in FIG. 37, in the shading fabric (1) for a curtain-type vertical blind according to the sixth embodiment, the first magnet (M1) and the second magnet (M2) may be installed in a horizontal band shape at the bottom of the first shading part (110) and the second shading part (120), respectively.

[0188] In addition, in a modified example of the sixth embodiment, a metal weight may be installed instead of the first magnet (M1) and the second magnet (M2) in the shape of a circle or a band installed at the lower end of each of the first shading part (110) and the second shading part (120) illustrated in FIGS. 36 and 37. In this case, the weight may also serve to cause the shading fabric (1) of the blind to sag downward and spread out.

[0189] The structure and operational effects of the vertical blind (100) manufactured using the shading fabric (1) for curtain-type vertical blinds according to the sixth embodiment of the present invention illustrated in FIGS. 33 to 37 are similar to those of the vertical blind (100) manufactured using the shading fabric (1) for curtain-type vertical blinds according to the fifth embodiment, and therefore, a description thereof will be omitted.

[0190] While the present invention has been described with reference to the embodiments illustrated in the drawings, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the appended claims.
