Description

[Detailed Description of the Invention] This invention relates to a blind in which a plurality of slats are arranged vertically and supported by hanging cords.

In conventional blinds of this kind, the hanging string is formed into a ladder shape by installing a horizontal string between a pair of vertical strings, and the horizontal string is made of two parallel strings, and a string is placed between the two strings. It is carried through a slat, but since the slat is long, it takes time to pass it between the two horizontal strings, so in order to simplify the assembly operation, a method was proposed in Japanese Utility Model Application No. 50-96342. One solution has been proposed. The blind disclosed in the publication has a hook part formed by cutting two sides of a triangle and hollowing it out on the slat, a hanging end forming a loop on the hanging string, and the hooking end of the hanging string is engaged with the hollowed out hooking part. Then, the hollowed out hook part is returned to its original state and the slat is supported on the hanging cord. Although this structure simplifies the installation of the slats, it still requires the use of a fixture that engages the hanging cord with the hook, and it is still necessary to return the hollowed-out hook to its original state. However, the cross section of the slat is curved for strength reasons, and the hook part must be returned along that curved surface. Even if it is returned completely, the cut part remains and is unstable. There is a high risk that the hook may rise or sag due to unexpected force being applied during use.

This invention takes the above points into account and provides a blind that has a simple structure, can carry slats on hanging cords with simple operation, and does not change in any way during use. In particular, a branch cord with an ampullae is provided on the hanging cord, a through hole is made in the slat, the branch cord is secured to the hole, and the through hole is formed in such a way that the branch cord cannot be pulled out. It is characterized by having slats supported on the string.

Hereinafter, an embodiment of this invention will be explained with reference to the drawings. In the drawings, 1 indicates a slat, 2 indicates a hanging cord,
Branch strings 3, which are thinner than the hanging string 2, are protruded from the hanging string 2 at parallel intervals above and below each slat 1, and the tip of the branch string 3 is provided with a spherical enlarged part 4. Each slat 1 has an insertion hole 5 on both edges in the width direction through which the enlarged portion 4 can pass, and an insertion hole 5 that extends continuously from the insertion hole 5 toward the side end of the slat 1 and allows the enlarged portion 4 to pass through. A through hole 8 consisting of a narrow locking hole 6 and a narrow locking hole 6 is bored. Moreover, a narrow portion 7 narrower than the width of the locking hole 6 is formed at the boundary between the insertion hole 5 and the locking hole 6 in the through hole 8 . In addition, a hole 9 is provided in the center of each slat 1 in the width direction, through which the blind lifting cord 10 is passed.

In order to carry the slat 1 having such a structure on the suspension string 2, as shown in FIGS. 2 and 3, the enlarged part 4 of the branch string 3 is inserted into the insertion hole 5 of the through hole 8 from the back side of the slat 1 to the front side. , and then pull the branch cord 3 toward the locking hole 6 of the through hole 8, and then pull the branch cord 3 through the locking hole 6.
By engaging with the slat 1, the slat 1 is supported on the suspension string 2. It is preferable that the side ends of the supported slat 1 are in contact with the hanging cord 1, so that the slat 1 is held between the opposing hanging cords 1, 1, and the slat 1 is prevented from shifting in the width direction.

As described above, according to the blind according to this invention, a branch string with an enlarged portion is provided on the hanging string, a through hole consisting of an insertion hole and a locking hole is provided in the slat, and the branch string is connected to the locking hole. In addition, the slats are supported on the suspension strings, and there is no fear that the branch strings will escape from the locking hole due to the ampulla, and the slats are held securely. Assembling is greatly facilitated by simply passing the branch cord through the insertion hole and moving the branch cord toward the locking hole. Furthermore, even if one of the front and rear suspension strings is raised and the other is lowered and the slat is tilted repeatedly, there is no unstable part in the supporting part, so it will always be supported normally. be.
