KR-102963265-B1 - Vertical blinds with increased stability

Abstract

The present invention provides a vertical blind having improved stability, wherein a first and second light-blocking section and a light-transmitting section are formed between the light-blocking sections, the degree of shading is controlled by folding the light-transmitting section, and one or more flexible bending sections are formed in the light-transmitting section to improve shape stability when the light-transmitting section is folded, wherein the flexible bending section involves relatively less warp and/or weft yarn in the conventional pattern of forming the light-transmitting section and has a lower density compared to other light-transmitting section structures, thereby forming a bend first when a folding force is applied to the light-transmitting section.

Claims (8)

1. In vertical blinds, First and second miners and A light-transmitting portion is formed between the above light-blocking portions, and The degree of shading is controlled by folding the light-transmitting part, and In order to improve shape stability when the light-emitting part is folded, one or more flexible curved parts are formed on the inner side of the light-emitting part, The flexible curved section involves relatively less warp and/or weft yarn in the conventional pattern forming the light-transmitting section, thereby having a lower density compared to other light-transmitting section structures, so that when a folding force is applied to the light-transmitting section, the curve is formed first, The above flexible curved portion is formed with a width (W) of 1 to 20% in a length area (L) of 5 to 30% from the boundary (250) of the light-transmitting portion to the inside of the light-transmitting portion, and A balance section is attached horizontally across the first and light-blocking sections and the light-transmitting section of the upper part of the vertical blind, and The above balance member has an adhesive surface on one side and is joined to the upper part of a vertical blind through a heat pressing device, The above light-transmitting part is a vertical blind formed with weft yarn having a relatively lower fineness compared to warp yarn to improve shape stability.

Description

Vertical blinds with increased stability The present invention relates to a vertical blind with improved stability, and more specifically, to a vertical blind with improved shape stability, such as foldability. Generally, blinds refer to a means of shading that regulates the amount of sunlight by having horizontal slats rotate or move up and down. Blinds are widely used in homes and offices because they create an indoor atmosphere that is lighter and more sophisticated than curtains, and provide privacy protection by blocking outside views. With the recent development of various technologies for blinds, vertical blinds—that is, those oriented vertically rather than horizontally—are being proposed. Korean Patent Invention No. 1027017 describes a structure in which multiple shading sections and curtain sections are woven integrally in an intersecting state. The basic principle involves constructing a single panel of fabric using a warp knitting method resembling a spiderweb, without distinction between warp and weft threads, in a regular, repetitive weaving process where the shading section cross-section is woven into a total of two sides and the curtain section, composed of mesh, is intersected. This results in a single-panel fabric structure where the shading section and the curtain section are integrated without seams, sewing, or the insertion of attachments. In the shading section where the two sides overlap, a connecting tissue formed between the first and second cross-sections is formed in a vertical form, identical to the vertical length of the shading section. In each curtain section, a central cross-section is formed between the first and second cross-sections, and a first connecting tissue and a second connecting tissue are formed on each side of the cross-section, respectively. By creating an automatic bending phenomenon in the curtain section, the characteristic of the curtain section is maintained through natural surface tension without artificial manipulation, thereby maintaining a regular horizontal shape of the curtain section. A single-width fabric weaving technology that achieves vertical formation without attachments for controlling light and ventilation when applied to a conventional vertical blind structure, and a curtain-integrated vertical blind using said fabric have been proposed. In addition, Korean Patent Publication No. 2016-122559 proposes a blind comprising a slat portion, a strip portion formed adjacent to at least one edge of the slat portion and extending along this edge, and a leg portion formed at one or more locations of the strip portion along the direction in which the strip portion extends and connecting the strip portion to the slat portion, wherein the strip portion is separable from the slat portion by cutting the leg portion, and the leg portion is formed of a fabric having a lower tensile strength than the strip portion and the slat portion. In addition, Korean Patent No. 1908979 relates to a curtain-integrated vertical blind comprising a plurality of blind sets including a light-transmitting part and a light-blocking part disposed on both sides of the light-transmitting part, wherein the blind includes a cutting band disposed between two adjacent blind sets; and a connecting thread connecting the blind sets and the cutting band and having a thickness thinner than the cutting band, wherein when the cutting band is pulled, the connecting thread is separated from the blind sets and the two blind sets are separated, wherein the light-transmitting part and the light-blocking part are each made of fabric material, and the upper part of the light-transmitting part is composed of a balance part for maintaining the blind shape, and the balance part is woven more densely than the light-transmitting part and less densely than the light-blocking part. The vertical blind proposed above performs the function of a blind through actions such as the light-transmitting section being folded and the light-blocking section overlapping each other. However, problems with the shape occur when the light-transmitting section is folded, causing a sunken area (see Fig. 1). Additionally, since the light-blocking section has a length of at least 2 to 3 meters in the vertical direction of the blind, vertical shape is not maintained, resulting in a lack of vertical stability and preventing the two light-blocking sections from adhering closely (see Fig. 2). Furthermore, when manufacturing the fabric, two or more blind sets are woven, and when separating them later, there are problems such as stray fibers remaining at the ends (edges) or improper separation (see Fig. 3). FIGS. 1 to 3 are photographs of products of the conventional invention exhibiting problems such as indentation, vertical misalignment of the light-blocking section, and separation abnormalities. FIG. 4 is an example photograph showing a light-transmitting flexible curved portion formed according to an embodiment of the present inve
