JPS6023440Y2 - Connecting strings for the slats of vertical blinds - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to the invention of a stacked slat panel in a vertical blind.

The slats of vertical blinds are suspended at their upper ends from a guide rail via a runner so that they can run freely, and by attaching a heavy hanging board to their lower ends, each slat is arranged vertically. .

In this type of vertical blind, the maximum separation distance at the upper end is regulated by a continuous piece that connects adjacent runners, so that the distance between the slats is within a predetermined distance when the blind is opened or closed.

However, since the lower ends of the slats are free, even if a heavy hanging board is attached, if an external force is applied, each slat will repeat its pendulum motion on its own and will no longer fulfill its role as a slat.

Therefore, in the past, a pole chain engagement part was provided on the vertical plate of each slat, and the pole chain was attached by engaging the pole chain to this engaging part, and the pole chain was connected to the adjacent vertical plates with a certain margin. Was.

When such a structure is adopted, all slats are connected to adjacent slats via hole chains, and this behavior is regulated, so each slat does not act on its own and can fulfill its function as a slat. .

However, when a pole chain is used, although the pole chain is easy to install, it is difficult to manufacture the pole chain itself, and the manufacturing cost is also extremely high, which is economically disadvantageous.

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional blinds, and the object is to provide a connecting cord for vertical slats in vertical blinds that is easy to manufacture, inexpensive, and easy to install. .

Hereinafter, details of the present invention will be explained along with embodiments shown in the drawings.

The slat indicated by the reference numeral 1 in the figure is formed into a band shape of a predetermined width from a thin metal plate or a synthetic resin sheet, and the upper end of the slat is suspended from a guide rail 2 via a runner (not shown) so that it can run freely. Each runner is screwed onto a screw shaft 3, and moves forward and backward according to the rotation of the screw shaft 3. Each launch is connected by a known connecting piece (not shown), and is regulated so that it does not take any independent action. .

As shown in an enlarged view in FIG. 2, a heavy hanging board 4 formed from a metal plate or the like into a rectangular flat plate shape is inserted into the bag-shaped part 1a at the lower end of each slat 1, and is inserted above both sides in the longitudinal direction. A hook-shaped engaging portion 4a that protrudes outward is formed at.

By the way, what is shown in FIG. 3 shows a connecting cord 5 according to the present invention.

This connecting cord 5 is made by, for example, twisting together a plurality of fibers, and then twisting a plurality of fibers together to form a single string, and there are hole-shaped parts 5a at predetermined intervals in the middle, which look like buttonholes. It is formed by knitting it separately.

These hole-shaped portions 5a are woven to have approximately 1/2 the thickness of the connecting string 5.

Therefore, the left and right cord-like parts 5b, 5 forming this hole-like part 5a
By hooking either one of the connecting cords 5 to the engaging portions 4a, the connecting string 5 can be engaged very easily.

At this time, the other string-like portion 5b remaining is positioned below the engaging portion 5.

Since this embodiment is constructed as described above, it can be attached extremely easily by hooking the hole-like part of the connecting string manufactured at an extremely low cost to the engaging part of the heavy hanging board, compared to the conventional hole chain. Not only is the cost low, but it is also extremely easy to install, and the installation work is simplified.

As is clear from the above description, according to the present invention, a fiber bundle made of multiple fibers is further knitted to form a string, and the string is separated into a pair of thin string-like parts on the left and right at a predetermined interval in the middle. Since it has a structure in which hole-shaped portions are formed, it is possible to obtain a connecting cord that is easy to manufacture, low cost, and extremely easy to attach.

Claims (1)

[Scope of utility model registration request] This is a string that connects the appendix plates of the slats 1 of a vertical blind whose upper end is attached to the guide rail 2 via a runner so as to be freely movable, and whose lower end is attached with a double slat 4. The shape is formed by further weaving the twisted fiber bundle as a string, and a buttonhole-like hole 5a is formed by weaving a pair of thin string-like portions 5b, 5b on the left and right at predetermined intervals along the way. This is a connecting string for a vertical slat panel in a vertical blind, in which one of the string-like parts 5b forming a hole-like part 5a is hooked on the engaging part 4a of the slat panel 4.
