[0001]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal blind, and more particularly to a cloth slat for a horizontal blind characterized by its shape and structure.

[0003]

[0002]

[0004]

2. Description of the Related Art As is well known, in a horizontal blind, a large number of slats made of narrow thin plate materials are rotatably and vertically arranged for adjusting a light shielding state by a ladder cord hanging from a head box. It is provided so that it can be hung while keeping the space between them, and can be operated from the state where the slats are folded up by the lifting cord to the state where they are lowered to cover the entire surface of the window.

[0005]

The slats used for this blind are
Generally, the width is about 10 to 50 mm and the length is 1
It is formed of a thin and thin plate material made of, for example, aluminum having a length of about m or more, and has a structure in which holes are provided at least at two positions spaced apart in the longitudinal direction in order to assemble the elevating cord. .

[0006]

And, such a blind has been used as a dimmer for windows in offices since ancient times.
Recently, the personality of the interior is also emphasized,
Further, there is a tendency that the demand gradually increases even at the personal and home level, and accordingly, various kinds of color slats are also provided. Also, while the metallic slats give the impression that they are cleanly arranged in a standard form, a blind in which the slats are covered with a bag-shaped soft cover is also proposed with the intention of improving the point of giving an office-like and cold feeling. We have (Actual Kosho 52-56001,
(Actual No. Sho 62-21298).

[0007]

[0005]

[0008]

By the way, since the conventional blinds are made of metal slats and have a mechanical and functional appearance, they give a cold feeling, but the problem is that the above-mentioned bag-shaped soft cover is used. It was solved by the proposal to cover the slats with, but the proposal did not replace the heat insulation effects such as the heat retention of cloth curtains.

[0009]

Therefore, by loosely enclosing the metal slats in a cloth bag, not only a new texture of the slats and a novel decorative effect are brought, but also an air layer is formed in the gap between the bag and the metal plate to prevent the temperature on both sides of the blind. It was thought that the above-mentioned buffer should be added.

[0010]

[0007] However, although it is easy to loosely wrap a metal plate slat with a loose cloth bag, there is a problem that the slat and the bag are misaligned during use when simply wrapping loosely. If such a form is simply adopted, the problem that the loose part of the bag is biased to a part of the long slats cannot be avoided, and as a result the design aesthetics are impaired in the sense of time. As a result, the adverse effects that impair the value of the blinds they possess were highlighted.

[0011]

In order to avoid this, for example, the present inventors have
Of the cloth bags that enclose the slats, there may be a difference in the lengthwise direction of the cloth on the front and back sides of the slats, and it is also possible to use a bag with wavy folds on the cloth on the front side. Thought. However, it is not always easy to make such a bag and to enclose it in the slats, and even with this method, it is not possible to suppress the movement of the back cloth wrapping around the surface side, so it is in use. However, it was impossible to prevent the problem that it is inevitable that the aesthetic sense in a design sense is impaired.

[0012]

The present invention has been made to solve various problems in consideration of the above practical problems, and the purpose thereof is basically the conventional metal plate slats. It is a slat that can form a blind that can give a aesthetic appearance that has not been obtained and a warm feeling that the cloth has, and at the same time, always keep the cloth-encapsulated state at the time of manufacture even during use. It is to provide a new blind slat having a property capable of

[0013]

Another object of the present invention is to provide a slat for a blind which has the above-mentioned properties and is easy to manufacture.

[0014]

[0011]

[0015]

The first feature of the blind slat of the present invention that achieves the above object is that it has shape retention and strength as a horizontal blind slat and is slightly curved in the width direction. Slat body consisting of a slender long plate, a flat backing adhesively fixed so as to cover the entire curved concave surface of the slat body, and a long slender body covering the entire curved convex surface of the slat body. It has pleats along the direction or a table cloth with random unevenness, and both widthwise edges of these table cloth and backing cloth are bound together outside the both widthwise edges of the slat body to form a bag shape. To have a configuration.

[0016]

Further, the present invention has a shape and strength as a slat for a horizontal blind, and a slat main body made of an elongated long plate material slightly bent in the width direction, and a curved concave surface of the slat main body. A flat backing cloth that is adhesively fixed so as to cover the entire surface, and a covering cloth that covers the entire curved convex surface of the slat body and has pleats along the longitudinal direction or random unevenness. Also, both widthwise edges of the backing cloth can be realized by a configuration in which both widthwise edges of the slat body are substantially aligned with and bonded to the slat body.

[0017]

In any of the above constructions, the slat body is covered with a bag, or the slat body is directly adhered to the slat body. The material of the backing cloth is not particularly limited, and may be a woven cloth or a non-woven cloth of natural fiber, regenerated fiber, or synthetic fiber. As the outer cloth, one that is pleated in advance or one that is preliminarily processed to have random irregularities such as a staggered pattern can be preferably used. Of course, it is also preferable to use a cloth having an appropriate print pattern.

[0018]

When a bag for enclosing the slat body is used, the slat body may be inserted after the bag is formed and the back cloth may be adhered, or after the back cloth is adhered to the back surface of the slat body. You may make it cover the front cloth and adhere the width edges of the front cloth and the back cloth. It is sufficient that the backing cloth is adhered to the slat body as long as the backing cloth is not displaced with respect to the slat body. Alternatively, it is of course possible to adopt a form of adhering in a strip shape in the longitudinal direction or another form. The front cloth, the back cloth, and the slat body may be adhered to each other by heat fusion or by using an adhesive, depending on the nature of the cloth itself. Not something. The outer cloth and the slats may be partially adhered to each other, whereby the outer cloth and the slats can be kept in a stable shape.

[0019]

The slat body is not particularly limited, but a conventional general aluminum thin plate (100 to 150 microns) can be used as it is.

[0020]

With the blind slat of the present invention having the above-mentioned structure, a hollow air layer that functions as a buffer air layer is formed in the surface cloth that substantially covers the surface of the slat body. When there is a temperature difference outside, it has the effect of heat retention and insulation. In addition to this, since the metal slat body does not appear on the surface, a new aesthetic,
Bring a decorative effect. Further, since the lining cloth is adhered to the slat body, there is no displacement in the longitudinal direction and the width direction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the embodiments shown in the drawings.

[0023]

FIG. 5 is a view for explaining a general structure of a blind to which the present invention is applied. In this figure, 20 is a head box, and a bracket (not shown) is provided along the upper frame of the window. It is attached to the provided curtain rail (not shown). And inside,
A shaft (23) around which a drum (not shown) around which the elevating cord (22) is wound is attached is provided along the longitudinal direction, and a tilt drum (25) around which the upper end of the ladder cord (24) is wound.
Similarly, a tilt shaft 21 to which is attached is installed. The lifting cord 22 is extended to the outside from a stopper portion 27 provided near the end of the head box 20 and is connected to an auxiliary cord 28 via a cord stopper 26. 29 is a tilter 3 near the end of the head box 20.
It is a rotary operation rod extended from 0 to the outside.

[0024]

Reference numeral 31 is a bottom rail assembled to the lower end of the elevating cord 22, and a large number of slats 32 are supported between the bottom rail 31 and the head box 20 by a ladder cord 24 at a constant vertical interval. .

[0025]

FIG. 5 shows a conventional example in which the slats 32 are made of thin aluminum plates.

[0026]

In contrast to the conventional blind having such a general structure, the blind of this example has a structure in which the slat body is covered with a cloth bag as described in each embodiment of FIGS. 1 to 4. It is characterized by eggplant.

[0027]

Embodiment 1 In FIGS. 1 and 2, reference numeral 1 is an aluminum thin plate which constitutes the slat body of this embodiment, and its size and shape are the same as those of the conventional aluminum slats shown in FIG. It can be configured as is.

[0028]

Reference numeral 2 denotes a cloth bag for enclosing the aluminum slat body 1, 3 denotes a back cloth adhered to the entire back surface of the slat body 1, and this back cloth 3 is a part of the cloth bag. I am doing it. In addition, the back cloth 3 in this example is made of cloth having a size that slightly protrudes from the side edge of the slat body 1 in the width direction.

[0029]

Reference numeral 4 denotes a cover cloth which covers the surface side of the slat body 1, and in this example, it is made of cloth which is pre-pleated in the longitudinal direction (a cloth having a wavy shape in the width direction).

[0030]

By incorporating the slat having the above-mentioned structure into the blind shown in FIG. 5, the slat has an appearance (design) that is warmer than that of a metal slat and has a pleated shape. The aesthetics of the structure are added to bring added value as an excellent interior, especially in a homely scene, which is not possible with conventional blinds. Further, functionally, it is between the slat body 1 and the pleated outer cloth 4. The formed space 5 plays a role of buffering the temperature difference between the inside and the outside of the blind, and brings about an excellent effect that can be replaced with a curtain which enhances the efficiency of heating and cooling in some regions.

[0031]

Furthermore, in order to form the slats encapsulated in the bag of this embodiment, for example, a flat cloth made of the back cloth 3 is adhered to the back surface of the slat body 1, and then the pleated outer cloth. When the slat of the present invention is manufactured by adopting the method of manufacturing by covering the slat 4 with it, the step of adhering the back cloth 3 to the slat body 1 and the front cloth 4 to the back cloth 3 are performed.
Since the production lines can be formed sequentially and relatively easily, such as the binding step of 1., the practically excellent effect of being able to assemble inexpensive production equipment is obtained. Embodiment 2 In the slats of this embodiment shown in FIGS. 3 and 4, the slat body 11 and the back cloth 13 of the cloth bag 12 are exactly the same as those of the above-mentioned embodiment 1, except that the outer cloth 14 is staggered. The difference is that it uses a cloth with a textured surface.

[0032]

Even with the slat having such a structure, the same effect as that of the first embodiment can be obtained.

[0033]

[0028]

[0034]

As described above, the blind of the present invention is
Not only does it eliminate the problem of metal slats in conventional blinds feeling cold, but in addition to the cloth bag itself providing a new texture and novel decorative effect, the bag always has an air layer on the surface side. The curved or random irregularities that are formed have the effect of giving the user a warmer sensation.

[0035]

Further, since the slat has an air layer in the outer cloth, in addition to the function as a window light control device, this air layer also functions as a buffer layer against the temperature difference between the inside and outside of the room. It has the effect of being able to substitute for the window heat shield of the curtain.

[0036]

Furthermore, in the slat of the present invention, since the back cloth of the bag is adhered to the slat body, the bag does not shift in the longitudinal direction or the width direction during use with respect to the slat body, There is also the effect that at the design stage of the blind, the aesthetic appearance that the creator intended can always be maintained.
