JPH09189181A - Slat for horizontal type blind and manufacture thereof - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain sufficient strength on the constitution of a horizontal type blind, to acquire soft feeling on appearance, to produce a favorable indoor atmosphere while easily executing a pattern, etc., and to improve a decorative effect by properly passing light. SOLUTION: A fabric woven by heat fusion yarn is cut in specified width, and material cloth 1 is formed. The material cloth 1 is heated, and the heat fusion yarn is welded mutually under the state, in which a fabric type is kept. The thermally fused material cloth 1 under the fabric state is molded in the shape 3 of the slats of a continuous blind by cold press working. The press- worked material cloth 3 is cut, and separated at every slat 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blade for a horizontal blind and a method for manufacturing the same, and more particularly to a blade for a blind and a method for manufacturing the same that can easily enhance light transmission and decorative effects.

[0002]

2. Description of the Related Art A horizontal blind in which a plurality of long strip-shaped blades are horizontally arranged in parallel is used as a window shade. Conventional horizontal blind blades are made of metal or hard plastic because of the necessity of strength to keep the elongated strip-shaped blades horizontal.

[0003]

However, the conventional blind composed of metal or plastic blades has a drawback that the room becomes too dark because almost no light is transmitted when the blind is closed. In addition, the conventional blind blades cannot meet the demand for a soft and relaxing indoor atmosphere because of the nature of the material, which gives a cold appearance. Moreover, it has not been easy to apply a pattern or the like to enhance the decorative effect.

In order to deal with such a problem, conventionally, a cloth made of natural or synthetic fiber is cut into a tape shape and attached to metal blades, or a cloth-made tubular bag is made to make this bag. By inserting metal blades inside,
An attempt has been proposed to obtain a soft appearance while maintaining the strength of the metal blade.

However, attaching such a cloth tape to metal blades or forming a bag and inserting the blades is troublesome, time-consuming, and costly.

Further, an attempt was made to impregnate a cloth with a resin to maintain hardness and make a blade, and although there are some patented ones, they have not been put into practical use and of course have not been used as commercial products.

The present invention has been made in consideration of the above-mentioned drawbacks of the prior art, has a sufficient strength for constructing a horizontal blind, and gives a soft appearance, and an indoor atmosphere is preferable. It is an object of the present invention to provide a blade for a horizontal blind, which can be easily made with a pattern or the like and can appropriately pass light to enhance a decorative effect.

[0008]

In order to achieve the above-mentioned object, the present invention provides a blade for a horizontal blind which is made of a woven fabric of heat-bonded yarn which is press-molded.

Further, in the present invention, (a) a step of forming a material cloth by cutting a woven fabric woven with a heat fusion yarn into a predetermined width,
(B) a step of heating the material cloth to fuse the heat-sealing yarns to each other while maintaining the woven form; And a step of (d) cutting the press-worked material cloth to separate each blade, and a method of manufacturing a blade for a horizontal blind.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a flowchart showing, in order, each step of the blind blade manufacturing process according to the embodiment of the present invention. 2 is an explanatory view of the processing state of the blade material in each step, and FIG. 3 is a perspective view of the blade material in each step.

First, the woven fabric using the heat-fusible yarn is cut into an appropriate length to form the material cloth 1 (step S1). As such a heat-fusible woven fabric itself, a commercially available one can be used (for example, Melty (trade name of Unitika)). This soft material cloth 1 (Fig. 3
A desired pattern is formed by printing on (A). The pattern printing may be performed in advance in the state of the woven fabric.

Next, the material cloth 1 is heat-treated in a high-temperature furnace to fuse the heat-bonding yarns of the woven fabric together (step S).
2). At this time, it is desirable that the heat-fusible yarn is not completely melted and the woven fabric shape is maintained. For this purpose, the heating temperature is adjusted appropriately. This is because if the temperature is too high, the cloth material will be completely melted into a resin film, and the effect of the blind blade of the textile material of the present invention will not be obtained.

Next, in step S3, the heat-fused raw material cloth 1 is sandwiched between an upper mold 2a and a lower mold 2b of a cold press 2 having a continuous blind blade-shaped pressing surface ( 2 (B)), cold press working is performed at room temperature (FIG. 2 (C)). In this example, in order to form a blade having a curved cross section, the blade is press-molded into a waveform having a continuous curved cross section. As a result, the cured corrugated material cloth 3 is formed (FIGS. 2D and 3B).

Subsequently, the corrugated plate-shaped material cloth 3 is cut to separate each blade 4 (step S4). As a result, the blade 4 having a curved cross-sectional shape is formed (see FIG. 2).
(E), FIG. 3 (C)). After that, using this blade 4,
A horizontal blind is formed according to a normal assembly process (step S5).

Since the blade 4 has a curved shape, it has a high rigidity and does not cause bending or bending even when arranged horizontally, and has sufficient strength and rigidity as a blade for a horizontal blind. In addition, since the heat-fusible yarn is in a woven state that is not completely melted, the feel and appearance are soft, and
Allows light to pass through appropriately.

FIG. 4 shows another example of the shape of the blind blade made of the heat-fusible woven fabric according to the present invention. (A) shows an expanded triangular shape, (B) shows an S shape, and (C) shows a stepwise cross-sectional shape. Similar to the curved shape described above, the blades having these shapes can also have sufficient rigidity as a blade for a horizontal blind.

[0017]

As described above, in the present invention, since the blades are formed by pressing using the woven fabric made of the heat-fusible yarn, it is possible to easily provide sufficient rigidity in the woven state. It is possible to obtain a soft appearance and to maintain a moderate brightness to create a relaxed and comfortable indoor atmosphere. Further, since it is a woven fabric, a decorative pattern or the like can be easily applied by printing.
