Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a support cord for supporting the slats of a horizontal blind. The present invention relates to a slat support cord for a ladder-shaped horizontal blind having a plurality of intermediate cord sections that horizontally connect vertical cord sections of books.

[Conventional technology]

Traditionally, horizontal blinds have used two ladder-shaped support cords of the type described above, which hang from the headbox of the blind at horizontal intervals, with the corresponding middle cords of the support cords hanging from the headbox of the blind. By supporting each slat in between, a horizontal blind consisting of a number of horizontal slats is formed. Additionally, in the case of large blinds with a large horizontal width, one or more similar support cords may be provided in the middle to prevent the slats from sagging in the center, and the slats may be placed over the middle cords. supports the middle part of the

Generally, the slats are provided with an insertion hole in the center for the insertion of the lifting cord, and the lifting cord extends vertically through the insertion hole of each slat, and is placed at the lowest position of the group of slats at its lower end. The slats are raised and lowered by connecting to the bottom rail and pulling the lifting cord into or out of the head box.

In such conventional horizontal blinds,
The lifting cord not only functions to raise and lower the slats as described above, but also regulates the lateral position of the slats since the lifting cord passes through the lifting cord insertion hole of each slat when the blind is assembled. It also serves to align a large number of slats in the vertical direction. This prevents the slats from shifting in the horizontal direction and causing the side edges of the slat group to become uneven.

However, when assembling the blinds, it is extremely troublesome to pass the lifting cords one after another through the lifting cord insertion holes provided in each slat, making the work of assembling horizontal blinds inefficient. In addition, because of this structure, if one of the slats becomes damaged and needs to be replaced, it is difficult to remove only the slat to be replaced, and the entire blind must be temporarily disassembled. It will have to be done.

Recently, in order to eliminate light leakage when the blind is closed and to create blinds with an excellent appearance, the lifting cord insertion holes in the slats have been eliminated, or the lifting cord insertion holes have been placed on the side edges of the slats to make them less noticeable. A blind using slats has been proposed. This eliminates the troublesome work of passing the lifting cords one after another through the lifting cord insertion holes provided in each slat when assembling the blind as described above, making it possible to assemble the slats more efficiently, and to provide the necessary Maintenance and repair of the blind can be simplified because only the slats that are suitable for use can be taken out individually.

However, in this type of blind, there is no means to prevent the slats from shifting in the horizontal direction, and the slats can move freely in the horizontal direction, causing the side edges of the slats to become uneven or, in some cases, This may cause the slat to become dislodged from the support cord. As a means to prevent such horizontal movement of the slat, an attempt was made to form a notch in the side edge of the slat and engage the vertical cord portion of the support cord with the notch to restrict the horizontal movement of the slat. However, this is insufficient to prevent deviations in the movement of the slats.

[Purpose of invention]

The purpose of this invention is to, like traditional blinds,
By passing the lifting cord through the insertion hole of each slat, there is no need to restrict the horizontal movement of the slats, so the blind can be easily assembled, and each slat can be easily pulled out. To provide a slat support cord for a blind which prevents the slat from easily coming off.

Another object of the present invention is to provide a slat support cord particularly suitable for a non-perforated slat type blind without a lifting cord insertion hole.

[Summary of the invention] The slat support cord for horizontal blinds according to the present invention is a ladder-shaped cord consisting of two vertical cord sections and a plurality of middle cord sections that horizontally connect the two vertical cord sections at intervals above and below. This slat support cord for horizontal blinds is characterized in that the middle cord portion is made of elastic fibers.

〔Example〕

FIG. 1 shows an embodiment of the slat support cord for horizontal blinds according to the present invention, and shows the state in which the slats are supported. In the figure, 1 is two vertical cord parts, 2 is the above-mentioned 2 vertical cord parts at a certain interval above and below.
A plurality of intermediate cord sections horizontally connect the vertical cord sections of the book; 3 indicates the slats supported by the supporting cords. The middle cord portion is made of elastic fibers.

When supporting the slats with this support cord, one vertical cord section is pulled from the other vertical cord section to elastically stretch the middle chord section, and the slat is inserted between them, allowing the elasticity of the middle chord section to be stretched. Therefore, the slat 3 is tightened between the two vertical cord sections 1, 1 above the middle cord section, and the slat is elastically clamped and fixed.

There are notches 4 on the side edges of the slats as shown in Figure 3.
If the vertical cord portion 1 of the slat support cord is formed and engaged with the vertical cord portion 1 of the slat support cord, horizontal movement of the slat can be more reliably prevented, and the vertical cord portion 1 of the slat support cord can be prevented more reliably. By engaging the notches 4, the slats are positioned and vertical alignment of the slats is ensured.

For example, as shown in FIG. 3, the slats 3 are elastically clamped between the vertical cord portions of the slat support cords (as shown by the broken lines in FIG. 3), and then the support cords are If the vertical cord part falls into the notch 4 by shifting the position, the position of the slat will be determined.

FIG. 4 shows a state in which the lifting cord 5 is attached to the slat supported by the support cord in this manner. The lifting cord 5 is disposed on one side edge of the slat 3, and allows the slat to be raised and lowered.

In order to further ensure the support of the slats, FIG. 5 shows that, instead of providing notches on the side edges of the slats as shown in FIG. An embodiment is shown in which a holding member 6 is provided to hold both side edges of 3.
Such a holding member is not necessarily attached to the vertical cord section, but may be attached on the middle cord section 2.

6, 7, and 8 each show a specific example of the slat support cord constructed as described above.

FIG. 6 shows a plurality of inelastic threads 7a as support cords.
The vertical cord portion 1 is formed by braiding the elastic yarns 7a and 7b, and the vertical cord portion 1 is formed by these yarns 7a and 7b, and the elastic yarn 7b is pulled out horizontally at the position where the middle cord portion 2 is formed, and the The vertical cord section is braided into vertical cord sections, thus forming an inelastic vertical cord section 1 and an elastic middle cord section 2.
This shows what was formed.

FIG. 7 shows that one vertical cord portion of the support cord is formed by braiding an inelastic thread 8a and an elastic thread 8b, and the other vertical cord portion is formed by braiding an inelastic thread 8c and an elastic thread 8d. The middle cord part is formed by elastic yarn 8 of both.
d and 8d are shown.

FIG. 8 shows that one vertical cord portion of the support cord is formed by braiding inelastic threads 9a and elastic threads 9b, and the other vertical cord portion is formed by braiding inelastic threads 9c and elastic threads 9d. The middle cord part is shown formed by elastic yarns 9b and 9d at every other cord.

[Effect of idea]

As mentioned above, the slat support cord according to the present invention facilitates the installation of the slat, and
The slats can be taken out individually, making not only the assembly of the blind but also maintenance and repair easier. Furthermore, when the slats are installed, there is no possibility of the slats shifting horizontally and coming off, and the slats are non-porous. But I can definitely support it.
