Pleated blind

Abstract

The invention provides a pleated blind which is provided with an upper curtain and a lower curtain and improves appearance. The pleated blind is provided with the components of the upper curtain (6U)which is suspended on an upper beam (1) and supports a middle beam (5), and a lower curtain (6L) which is suspended on a middle beam (5) and supports a lower beam (7). Furthermore, when an upper lifting rope (3U) is used for lifting or lowering the middle beam (5) and a lower lifting rope (3L) is used for lifting or lowering a lower beam (7), at least one of the upper lifting rope (3U) is configured in a manner of capable of being seen from one side of the upper curtain (6U), at least one of the lower lifting rope (3L) is configured at the other side of the upper curtain (6U) and is configuredin a manner of uncapable of being seen from the side. Furthermore the pleated blind is configured in a manner: when the middle beam (5) is at a lowest position, the front side of the middle beam (5)is in a state of inclining downwards, and furthermore when the middle beam (5) is at a highest position, the middle beam is at a state that inclination is reduced.

Description

technical field [0001] The present invention relates to a pleated blind in which a curtain that can be bent vertically is supported from an upper beam, and the curtain can be raised and lowered to adjust the amount of daylighting. Background technique [0002] In the pleated shade, a vertically bendable screen is suspended from an upper beam, and the amount of daylighting is appropriately adjusted by raising or lowering the screen with an operating device. [0003] Generally, in a pleated blind that hangs and supports one curtain from an upper beam, the curtain is made of drapery fabric (light-shielding fabric) or lace fabric (light-emitting fabric), and the amount of daylighting can be adjusted by folding the curtain. [0004] In addition, as a kind of pleated blind, there is a pleated blind as follows: that is, as a cord that can be bent into a Z shape in the vertical direction, it is configured by using an upper cord and a lower cord formed from a plurality of fabrics, an...

Problems solved by technology

[0014] In the above-mentioned conventional pleated shades, there is a problem that, for example, when fabrics of different colors are used for the upper and lower shades, the upper and lower lift cords and the fabric (especially the upper shade) have a problem of color difference. Coordination leads to poor aesthetics

[0015] In addition, in the above-mentioned conventional pleated blinds, although it is possible to use the upper curtain and the lower curtain to switch the fabrics that block external light by lifting the center beam, it is also required to improve the aesthetics as much as possible.
