Description

[Detailed description of the invention] (a) Industrial application field This invention relates to the field of improving means for opening and closing curtains in the field of manufacturing curtains.

(b) Conventional technology In the case of conventional vertically opening/closing curtains, a gear is linked to a rod provided at the upper edge of the curtain to wind it up, or a guiding device such as a string for opening/closing the curtain is attached to the base fabric of the curtain. Generally, it is installed on the front or back side or on the side edge, etc., and the operating string etc. has been constructed so that it can be operated by being guided by an attached guide device (see Utility Model Publication No. 52-19709, 55-
30377, 56-8536, 57-21329, 57-46871) (c) Problems to be solved by this invention The conventional opening and closing of the top and bottom of the curtain is performed by the structure and device described in (b) above. This not only makes the curtains heavier as a whole, but also makes it difficult to easily replace the curtains or wash them without removing them. Therefore, managing the curtains was extremely troublesome. At times it was almost impossible for the family to survive.

(d) Means for solving the problem In order to solve the above problem, this invention weaves strings at regular intervals in the vertical direction of the curtain, and when weaving the strings, weaving them in at regular intervals. The woven fabric is cut into a curtain with the direction of the weaving strings being horizontal and the direction perpendicular to the strings being vertical, and the hem of the curtain is placed near the hem of the curtain. One end of the string for raising and lowering is sewn, the other end of the string is passed through the floating fabric part, guided toward the upper edge of the curtain, and the remaining end is used as an operating string for opening and closing the curtain. The string is guided to the side of the curtain via a hanging device provided on the upper extension line of the string, and the curtain is opened and closed up and down by pulling down the end of the string or loosening its operation.

(e) Action By pulling down the curtain opening/closing operation string, the string is guided by the floating part of the curtain surface, and the woven string part of the curtain is used as a fold to fold the curtain sequentially from its lower edge. By folding the curtain upwards and stopping the operation of the operating string halfway, the lower edge of the curtain is kept at the intended height, and by loosening the pull of the operating string, the floating section is guided. Accordingly, the folded part is pulled by the weight of the lower part of the curtain and unfolds sequentially from the upper part, and the lower edge of the curtain moves to the intended low position, but the operation of the operating string is stopped. The lower edge of the curtain thus remains in a position corresponding to its operation.

(f) Example To explain the example of this invention with reference to the diagram, the woven strings 1, 1', and 1'' are woven at constant intervals (approximately 20 cm) in the vertical direction. approx. 20
cm), and then the woven fabric, which has floating sections 2, 2', 2'' by floating it over a length of about 3 to 5 cm, is woven in the direction of the woven strings 1, 1', 1''. Cut it horizontally and vertically in the direction orthogonal to the same direction to form curtain 3,
The lifting cords 5, 5', 5'', one end of which is sewn to the hem portions 4, 4', 4'' of the same 3, are pulled out above the same part 2 by submerging the floating fabric parts 2, 2', 2'', 2. , the remaining end is an operating string 6 for opening and closing the curtain up and down,
6', 6'', and if necessary, the upper edge of the curtain 3 and the operating string 6-6'' are held by a holding tube 7 of the curtain, and the tube 7
is the length of the width of the curtain 3, and as shown in Fig. 3, it is divided into two upper and lower stages, the upper part of which is the curtain operating string tube 8, and the lower part of which is the clamp tube 9 of the curtain 3. An operating string groove 8' is provided along the entire length of the side surface of the clamp tube 9, and a clamp groove 9' is provided along the entire length of the side surface of the clamp tube 9.

When using it, the hook rod 11 is removably inserted into the hook tube 10 formed by cross-sewing the upper edge of the curtain 3, and the hook rod 10 and the same 11 are inserted into the clip tube 9.
The curtain 3 is hung outward from the pincer groove 9', and the tips of the operating strings 6, 6', 6'' are inserted into the string holes 12, 12', 12'' provided in the side wall of the operating string tube 8, and the operating strings 6, 6', 6'' are inserted into the operating groove. 8', guide the inside of the operating string guide tube 8 to the outside of the right end of the tube 8 in the drawing, hang it down to an arbitrary length, and connect the operating string 6.
-6″ tips are gathered together to form a handle 13, and the same 13
The curtain 3 can be opened and closed up and down by pulling down or loosening it, but if necessary, the lower edge of the curtain 3 can be sewn horizontally to form the plastic bag 1.
4, a shaping plate 15 of a known shape is removably inserted into the curtain 14, the horizontal tension of the curtain 3 is adjusted with the same 15, and the shape of the lowest layer when the curtain 3 is pulled up is It also arranges things.

However, if it is not appropriate to use the holding tube 7 when installing the curtain 3 at a required location, known suspension devices 16, 16 may be placed at appropriate locations above the extension lines of the lifting cords 5, 5', 5''. ', 16'' is provided, and the same 16-
16', as shown in FIG.
6'' is guided to the right in the drawing and converged on the right side of the curtain 3, with the converging end serving as a handle 13.

(d) Effect Since this device has the above properties and effects,
A curtain that can be opened and closed up and down can be constructed using only its base fabric and operating strings, and no auxiliary tools or devices are required.
It is easy to manufacture, and the curtain 3 can be easily manufactured by simply removing the handle bar 11, pulling out the curtain from the clip groove 9', unbundling the handle, and pulling out the operating string 6-6'' from the string hole 12. Not only can washing, repair, etc. be easily managed by removing the curtain, but also such removal work is not necessary when the holding tube 7 is not used, which is very convenient in terms of use and maintenance of the curtain. It's convenient.
