Blind

Abstract

A blind so formed that at least one lateral side edge of a louver is pointed in a direction different from the direction of the middle part thereof in cross section, wherein the louver of soft cloth or soft resin is formed in a shape with pleats such that at least one lateral side edge thereof is pointed in the direction different from the direction of the middle part thereof in cross section, whereby, even if the louver is not formed or processed as such a hard louver as to always hold all the length thereof in such a shape pointed in a direction different from the direction of the middle part thereof in cross section, the blind having the louver with pleats can be manufactured at a low cost, and use, control, and transport configurations can be handled in the same manner as in a conventional normal band-shaped cloth louver and a soft resin louver.

Description

technical field [0001] The invention relates to a shutter, in particular to a shutter in which the shutter is suspended on each bracket of a group of rollers moving along the track through a shutter hook. Background technique [0002] Conventionally, for louvers, in order to make them three-dimensional and luxurious, as a shape in which at least one side edge in the width direction of the horizontal section points in different directions relative to the middle part, there is an inverted S-shaped cross section of the louver ( technology with inverted S-shaped pleats) (for example, JP 7-14623). For the louver, it is necessary to make the louver itself hard and form or process it into an inverted S-shaped cross-section. At the same time, the louver hook for hanging the louver by the rollers and the counterweight installed at the lower end of the louver must be formed. The cross section is an inverted S shape. That is, as shown in FIG. 24 , for example, the louver hooks 51 are...

AI Technical Summary

Problems solved by technology

[0003] However, conventionally, in the louver whose cross section is an inverted S-shape in which at least one side edge of the louver in the width direction of the horizontal section is directed in a different direction relative to the middle part, there is a problem that it is necessary to use a hard material in advance. The louvers are formed one by one into an S-shaped cross-section, or even if the louvers themselves are made of cloth, they must be processed into an inverted S-shaped cross-section through hard processing with paste attached. Therefore, the louvers The unit price of its own manufacturing has increased, and it has become an expensive shutter

In addition, since the louvers are hard, they are not as flexible as the usual strip-shaped cloth louvers or soft resin louvers, so there is a problem that loud noises are generated due to the collision between the louvers, and at the same time , the louvers cannot be bent in the longitudinal direction, and since the overall length of the louvers usually maintains an inverted S-shaped cross-section, the volume increases, which brings troubles to management and transportation, and the cost of management and transportation also increased
