JPH0688470A - Slat of horizontal blind - Google Patents

Abstract

PURPOSE:To take in soft light without causing a hindrance for elevating and angle adjusting operation. CONSTITUTION:A slat 14 is constituted so that a film 16 provided with shading parts 17 to intercept light and many fine transparent parts 18 to transmit light is stuck on a transparent slat base plate 15. Because the transparent part 18 is not a void hole, even if an inserting hole for inserting an elevating cord is formed on the slat 14, any cutout is not generated on the circumferential edge of the inserting hole by means of the transparent part 18.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal blind slat.

[0002]

2. Description of the Related Art In a horizontal blind 1 shown in FIG. 4, a slat 4 having a large number of steps is suspended from a head box 2 via a ladder cord 3, and a bottom rail 5 is suspended from a lower end of the ladder cord 3. There is.

Two lifting cords 6 for raising and lowering the slat 4 are passed through each slat 4, and one end thereof is connected to the bottom rail 5. The other end of the lifting cord 6 is guided inside the head box 2 to one side thereof, and hangs down from the head box 2 through a cord stopper 7 provided on one side of the head box 2 and is connected to a cord equalizer 8. There is.

The code equalizer 8 has an operation code 9
Is connected to the bottom rail 5. The other end of the operation cord 9 is connected to the bottom rail 5. The cord stopper 7 is a known one that holds the lifting cord 6 between the fixed roller and the movable roller to prevent the lifting cord 6 from being pulled into the head box 2 due to the weight of the slat 4 when the operating cord 9 is not operated. is there.

With the above construction, if the operation cord 9 is operated to pull out the lifting cord 6 from the head box 2,
The bottom rail 5 is pulled up, and is sequentially pulled up by the bottom rail 5 from the lower slat 4, and the weight of the bottom rail 5 and the slat 4 is used to pull the lifting cord 6 into the head box 2 to lower the bottom rail 5. Then, the upper slats 4 are supported by the ladder cord 3.

A lifting cord 6 is provided on one side of the head box 2.
An operating rod 10 is hung adjacent to the slat 4, and by rotating the operating rod 10, the angle of each slat 4 can be adjusted via an angle adjusting shaft (not shown) in the head box 2 and a ladder cord 3.

Lateral blind slat 4 as described above
One example is shown in FIG. That is, a large number of fine holes 11 are formed in the slat 4 formed of a thin aluminum plate by punching. In the horizontal blind 1 using such slats 4,
Even if the slat 4 is tilted in the vertical direction to be in the fully closed state, it is possible to secure indoor privacy while taking in soft light from the minute holes 11.

[0008]

In the conventional slat 4 shown in FIG. 3, a micro hole 11 is formed by punching and then an insertion hole 12 for inserting the elevating cord 6 is formed by punching.

However, in such a slat 4, the minute hole 11 interferes with the peripheral edge of the insertion hole 12 to form a notch 13. Therefore, the lifting cord 6 that is inserted into the insertion hole 12 is caught in the notch 13 and the slat 4 is inserted.
The lifting and lowering operation and the angle adjusting operation may be hindered, or the notch 13 may rub the lifting and lowering cord 6 to cut the lifting and lowering cord 6.

It is an object of the present invention to provide a horizontal blind slat which can take in soft light and which does not hinder the lifting and angle adjusting operations.

[0011]

In order to achieve the above object, the present invention provides a transparent slat substrate with a film provided with a light-shielding portion for shielding light and a large number of fine transparent portions for transmitting light. The slat is constructed.

[0012]

[Function] Since the transparent portion that transmits light is not a through hole, even if an insertion hole for inserting the elevating cord is formed in the slat, the transparent portion must notch the peripheral edge of the insertion hole. There is no.

[0013]

1 and 2 show an embodiment of the present invention. The slat 14 shown in FIG. 1 is constructed by adhering a film 16 to a slat substrate 15 formed of a transparent synthetic resin plate.

The film 16 is formed by printing a mesh pattern on a transparent base material, and is composed of a light-shielding portion 17 which shields light and a large number of minute transparent portions 18 which transmit light. Then, as shown in FIG. 2, the slat 14 has a film 16 adhered to the slat substrate 15, and then the lifting cord 6
The insertion hole 19 for inserting the is punched.

The slat 14 as described above can take in soft light from the transparent portion 18 even when the slat 14 is in the fully closed state like the slat 4 of the conventional example.

Since it is not the through hole that takes in the light but the transparent portion 18, even if the transparent portion 18 interferes with the peripheral edge of the insertion hole 19, the notch as in the conventional example does not occur.

Therefore, since the lifting cord 6 and the peripheral edge of the insertion hole 19 are not caught, the slats 14
It is possible to smoothly move up and down and adjust the angle, and it is possible to prevent the lifting cord 6 from being cut.

The transparent portion 18 is a transparent film 1.
Since it is formed as a pattern to be printed on 6, it is also easy to change the diameter and interval of the transparent portion 18 by changing the pattern to change the light transmission characteristics.

Further, the material of the slat substrate 15 may be changed to adjust the light transmission characteristics.

[0020]

As described above in detail, according to the present invention, it is possible to provide a lateral blind slat capable of taking in soft light and having no hindrance to the lifting and angle adjusting operations. Exert.
