Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention supports a plurality of slats horizontally by means of ladder-like support cords near both ends of the slats and, if necessary, at an intermediate position, and lifts and lowers the slats. The present invention relates to a type of blind equipped with a lifting cord, a so-called horizontal blind.

[Background of the idea]

Generally, horizontal blinds have a plurality of slats supported horizontally at regular intervals vertically by ladder-like support cords near each end of the slats and, if necessary, at one or more locations in between. By moving the front and rear vertical cord portions of this ladder-like support cord relatively up and down, the slats are tilted to adjust the light shielding, and light is inserted through the lifting cord insertion hole provided in the center of each slat. A lifting cord is passed vertically, its lower end is fixed to a lower plate placed at the lower end of the row of slats, and the slats are raised and lowered, that is, the blinds are opened and closed, by winding up and lowering the lifting cord. It is configured as follows.

As mentioned above, the above-mentioned elevating cord has the function of controlling the elevating and lowering of the slats, and because it extends vertically through the elevating cord insertion hole provided at the same position on each slat, it also controls the horizontal movement of each slat. It also plays the role of regulating the slats and aligning a large number of slats in the vertical direction.

However, in the structure of the conventional horizontal blind as described above, when the slats are tilted to a vertical position, outside light leaks into the room through the elevating cord insertion hole, impairing the light-shielding function of the blind.
Furthermore, it is not desirable in terms of the appearance of the blind that a large number of elevating cord insertion holes are visible over the entire surface of the blind when the blind is closed.
In addition, in the conventional structure where the lifting cord passes through the lifting cord insertion hole provided in each slat, when the slat is tilted, the edge of the lifting cord insertion hole of each slat hits the lifting cord. There is also the problem that the tilting action of the slat is limited and therefore the slat cannot be tilted to a completely vertical position. Furthermore, it was difficult to remove the slats, and the task of replacing damaged slats was extremely troublesome.

[Purpose of invention]

The purpose of the present invention is to eliminate the above-mentioned drawbacks of conventional blinds, prevent external light from leaking through the small holes of each slat, and improve light blocking performance by making the slats completely tiltable. To provide a horizontal blind that can be easily replaced.

[Summary of the idea]

A blind according to the present invention is a blind of the above type, in which each slat is formed with at least one slot through which the middle cord of the ladder-like support cord can pass, and the slat is placed on the middle cord of the ladder-like support cord. place the middle cord, pull out a part of the middle cord from the slot to the top surface of the slat, insert a locking piece under the pulled-out part of the middle cord, and pull it onto the top surface of the slat using the middle cord pulled-out part. This feature is characterized in that the slats are fixed to the middle cord of the ladder-like support cord by pressing and fixing them, and the above-mentioned slots are hidden.

[Example of idea]

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Figure 1 is a front view showing the blind of the present invention.
In the figure, 1 is a head box, 2 is a lower plate, and 3 is a slat. Similar to a normal blind, each middle cord 4b of a pair of ladder-like support cords 4, 4 hanging from the head box 1 has a slat 3 near both ends. It is supported horizontally by placing the (See Figures 2 and 3) In the center of each slat 3, as shown in Figure 4, the middle cord 4b can pass through at least one position supported by the middle cord 4b of the ladder-like support cord 4. A slot 6 is provided.

Using this slot 6, the central part of the middle cord 4b located on the lower surface of each slat 3 is pulled out to the upper surface of the slat, and a thin plate of metal such as aluminum or plastic is placed under the pulled-out portion of the middle cord 4b. By inserting the locking piece 7 and pressing and fixing it against the upper surface of the slat 3 by the middle cord pull-out portion, the slat 3 is fixed to the middle cord 4b of the ladder-like support cord, and the above-mentioned groove The holes 6 are hidden to eliminate holes through which light leaks throughout the slat.

In the illustrated example, the locking piece is shaped like a "sleeve" and has a size and shape that prevents it from passing through the slot 6, but the locking piece may have other shapes.

The ladder-like support cord 4 has vertical cord portions 4a, 4
A guide ring 4c for inserting the lifting cord is formed at an appropriate interval vertically, and the lower end of the lifting cord 5 is fixed to the lower plate 2 disposed below the group of slats. It is guided into the headbox 1 through the guide ring 4c, and then led out of the headbox again from near one end of the headbox 1 via a suitable stopper device 8, forming an operating section.

The guide ring 4c for inserting the lifting cord may be knitted integrally with the ladder-like support cord, or a ring made of metal or resin, or a ring such as a string may be separately attached later. Alternatively, a double middle-stage cord may be used and passed between the two middle-stage cords.

Further, it is preferable that the locking piece 7 is shaped like a gourd as shown in FIG. 4, and the central part is made narrow, since this makes it difficult for the middle cord 4b to come off.

FIGS. 5A and 5B are diagrams showing a comparison of the tilting states of the slats of the blinds of the present invention. FIG. 5A shows the conventional blind, and FIG. 5B shows the blind of the present invention. As shown in FIG. 5A, in the conventional blind, the lifting cord 5 extends to the lower plate through the lifting cord insertion hole 9 provided in the center of each slat, so when the slat is tilted, the lifting cord 5
However, in the blind of the present invention, the lifting cord 5 is placed on the outside of the slat, so the tilting of the slat is restricted and the slat cannot be tilted to the vertical position. It can be tilted to a completely vertical position without being restricted by conventional tilting movements.

[Effect of the invention] Since the present invention has the above-mentioned structure, the groove hole 6 of the slat is closed by the locking piece 7, and when the slat is fully closed and tilted, the elevating cord is inserted through the elevating cord insertion hole as before. No light leaks, and the problem of the side edge of the lifting cord insertion hole in the slat coming into contact with the lifting cord when fully closed and tilting, which prevents further tilting, is solved, and it has excellent light blocking properties. We can provide you with blinds.

Further, the slats can be easily removed by removing the locking pieces, and the slats can be easily replaced, which is useful as a blind.
