Abstract

PURPOSE:To enhance the sound isolating characteristics and eliminate coolness in the sense by providing a long stretching, sack-shaped textile which enwraps the body of a slat, equipping this textile with a number of welding spots at the two edges across the width at short intervals in the longitudinal direction, and thereby producing wrinkles on the textile as stressed in the longitudinal direction. CONSTITUTION:The body 1 of a slat made from an Al sheet is interiorly fitted to a sack 2 made of a long stretching cloth, and the edges of the slat body of the sack 2 are welded at several millimeter intervals while being stressed in the longitudinal direction to form flares 3. Inside of the sack 2, a hollow air layer is formed to serve as a buffer air layer, and a cloth slat is accomplished having wrinkles 3 when viewed from the outside. This enhances the sound isolating effect and eliminates metalic coolness in the sense.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a cloth blind, and more particularly to a cloth blind having characteristics in the shape and structure of the slats.

(Prior Art) As is well known, a blind has a large number of narrow thin plate-shaped slats suspended from a head box at a predetermined distance from each other by a lifting cord hanging from a head box.
These slats are rotatable using a ladder tape to adjust the light-shielding condition.The slats have a width of about 10 to 50 cm and a length of 300 m to 300 m.
It is a long, thin board with a length of about 3,000 m or more, and is equipped with holes in at least two locations for the vocal cord for raising and lowering the slats, and has a strength relationship that satisfies these requirements. Therefore, slats are generally constructed using a metal material, usually a lightweight aluminum alloy plate.

This blind has been used as a light control device for windows in offices and other offices for a long time, but recently. There is a tendency for holly wood to be used as an interior decoration material, and demand for it is gradually increasing on a personal and household level, and in response to this trend, many types of colored slats are being offered.

In addition, blinds with bag-shaped soft covers covering the slats are also used to solve the problem of creating a cold feeling in offices due to the neatly arranged metal slats. Proposed. (Utility Model Publication No. 52-56001, Utility Model Application No. 62-21298).

By the way, the above-mentioned proposal of covering the slats with a bag-like soft cover solved the problem that conventional blinds used metal slats, which gave them a mechanical and functional beauty but gave them a cold feeling. Although it has been improved to give a vague feeling, it is only a tactile and sensory effect, and it can be replaced by the insulation effect such as the heat retention of cloth curtains. It's not a thing.

In view of the current state of conventional blinds as described above, the present invention not only eliminates the perceived coldness of blinds due to the metal slats, but also functions as a window light control device. In addition, the purpose of this invention is to provide a blind that can be expected to have a heat-insulating effect that can be used as a window light control device during the cold season in relatively cold or temperate regions.

Another object of the present invention is to eliminate the risk of injuring hands and other bodies by covering metal slants with a cloth bag, and to provide a new texture and novel decorative effect to the slats covered with the cloth bag. Our goal is to provide blinds that can be brought to bear.

(Means for Solving the Problems) A blind according to the present invention that achieves the above object is characterized by a slat main body made of an elongated plate-like member that has shape retention and strength as a slat for a blind, This is a blind equipped with slats made of a long bag-shaped raw cloth that wraps around the main body, and on both widthwise edges of the raw cloth, the raw cloth is wrinkled in the longitudinal direction at short intervals along the longitudinal direction. The structure has a large number of welding points.

In the above configuration, the material of the raw fabric bag is not particularly limited, and may be any of woven fabrics and nonwoven fabrics made of natural fibers, recycled fibers, and synthetic fibers.

Further, the spacing between the welding points is not particularly limited, nor is the size of the pleats caused by creasing, but it is generally preferable to provide them at intervals of about a few squares.

Furthermore, the material of the slat body is not particularly limited as long as it has the necessary strength, but generally a conventional aluminum thin plate (50 to 200 microns) can be used.

The pleats that are applied to the bag-shaped raw cloth that covers the slat body may be applied only to the front side of the slat, or may be applied to both the front and back sides of the slat.

(Function) By having the above-described structure, the blind of the present invention forms a hollow air layer that acts as a buffer air layer inside the cloth bag that covers the slat body, and this can be used when there is a temperature difference between indoors and outdoors. Provides heat retention and insulation effects.

In addition, since the metal slat body does not appear on the surface, it brings a new aesthetic and decorative effect.

(Example) The present invention will be explained below based on Examples shown in Examples.

FIG. 313 is for explaining the general configuration of a blind to which the present invention is applied.
o is a head box, and the blind is attached along the upper frame of the window with a bracket (not shown).

Inside, a lifting cord 22 is provided along the longitudinal direction, and a tilt shaft 23 on which a tilt drum 25 around which the upper end of a ladder tape 24 is wound is mounted is also provided.

The lifting cord 22 extends outside from a stopper portion 27 provided near the @ portion of the head box 20, and is connected to an auxiliary cord 28 via a cord stopper 26. 2
Reference numeral 9 denotes a rotary operating rod extending outward from the tilter 30 near the end of the head box 20.

31 is a bottom rail assembled to the lower end of the lifting cord 22, and this bottom rail 31 and the head box 2
0, a large number of slats 32 are supported by ladder tapes 24 at regular intervals vertically.

This IF3 diagram shows an example in which the slat 32 is made of a thin aluminum plate.

In contrast to the conventional example described above, the blind of the present example is characterized by a structure in which the blind is covered with a pleated cloth bag, as one of the slats is representatively shown in FIGS. 11 to IF5.

That is, in Fig. 1, numeral 1 is a thin aluminum plate forming the slat body of the slat of this example, and its dimensions, shape, etc. can be constructed using the same material as the conventional aluminum slat shown in Fig. 3. , in this example, it has a slightly curved shape that is convex upward.

Reference numeral 2 denotes a cloth bag that wraps around the aluminum slat body, and is provided so as to be longer than the slat body with a margin of 1 minute for pleats.

In this example, one slat body is placed inside this long bag 2.
After lining the slats, the edges on both sides of the slat body of the bag are wrinkled in the longitudinal direction so as to form a pair, and welded at intervals of several meters to create pleats in a direction perpendicular to the longitudinal direction of the slats. In this way, the raised folds 3 shown in FIG. 212 are formed.

4 indicates the welding point.

With this configuration, a hollow air layer is formed inside the pleated portion 3 in terms of internal structure, and the fabric slat has pleats at intervals of several inches in appearance.

After the fabric slats have been pleated, finish the edges, remove fraying from both sides, and drill holes for the lifting cords to pass through, and use them in the same way as the blind slats explained in Figure 3 above. This completes the blind with pleated fabric slats.

In addition, in the above example, pleating is done at regular intervals, but
This may be freely determined, such as having more pleats near the ends and no pleats in the center, or the size of the pleats may be changed to match the printed pattern of the cloth bag.

(Effects of the Invention) As described above, the fabric blind of the present invention solves the problem of the metal slats feeling cold to the touch, and the fabric bag allows the slats to touch the edges of the 4° side + 111 parts when touched by a human. This eliminates the risk of injury to the body or body, and the pleated cloth bag provides a new texture and novel decorative effect.

In addition to its function as a window dimmer, the slant has an air layer in the folds of the fabric bag, which acts as a buffer against temperature differences between indoors and outdoors, keeping the bag cool in the summer and warm in the winter. It has the effect of replacing the window light control that curtains have.

In addition, the slatted cloth bag can be easily removed and washed, so it has the effect of being able to be used as a cloth blind in a clean state at all times.
