DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, a roman shade curtain and a roman shade using the same according to the present invention will be described in more detail with reference to the accompanying drawings.

The present invention relates to a roman shade.FIG. 3is a perspective view showing a first exemplary embodiment of a roman shade according to the present invention;FIG. 4is a partially enlarged view showing a first exemplary embodiment of a roman shade according to the present invention; and FIG. is a partial side cross-sectional view showing a first exemplary embodiment of a roman shade curtain according to the present invention.

The roman shade curtain according to the present invention is configured to include a curtain40woven by interweaving warps42and wefts44with each other and including reinforcing wefts46interweaved with the warps42;

and cord lines50passing between the wefts44and the reinforcing wefts46and then fixed to a lower end of the curtain40.

In addition, the roman shade according to the present invention is configured to include a rotating bar10; a frame having a shaft of both ends of the rotating bar10connected to both ends of an inner side thereof; a traction line30installed at one end of the rotating bar10to adjust rotation of the rotating bar10; the curtain40woven by interweaving the warps42and the wefts44with each other, having an upper end connected to the frame20, and including the reinforcing wefts46interweaved with the warps42; and the cord lines50having one end fixed to the rotating bar10and the other end passing between the wefts44and the reinforcing wefts46and then fixed to the lower end of the curtain40.

Hereinafter, the respective components of the roman shade curtain and the roman shade using the same according to the present invention will be described in detail.

The rotating bar10, which is a component rotated in order to operate the roman shade according to the present invention, has the shaft connected to a frame20to be described below.

The frame20has both ends of the inner side connected to the shaft of both ends of the rotating bar10as shown inFIG. 3, thereby allowing the rotating bar10to be rotated with respect to the frame20. The frame20is attached to a position which the roman shade according to the present invention is installed to serve to support the roman shade.

The traction line30is wound around one end of the rotating bar10to serve to adjust the rotation of the rotating bar10. Since a structure in which the traction line is connected to the rotating bar10is well-known, a detailed description thereof will be omitted.

The curtain40is woven by interweaving the warps42and the wefts44and has the upper end connected to the frame20to serve to directly shield sunlight or hide a thing.

The reinforcing wefts46, which are a first exemplary embodiment of the roman shade curtain and the roman shade according to the present invention, are components woven integrally with the curtain40at the time of weaving the curtain40since they are placed over the wefts44and are interwoven with the warps42as shown inFIGS. 4 and 5and allowing cord lines50to be described below to pass therethrough. A plurality of reinforcing wefts46may be installed in a length direction of the warp42. Places through which the cord lines50pass increase by the number of reinforcing wefts46to be installed, such that the number of layers formed when the roman shade according to the present invention is folded is determined.

A tension maintaining bar49is a component installed at a lower end of the curtain40while having a predetermined weight as shown inFIG. 3to allow gravity corresponding to the predetermined weight to be applied to the curtain40, thereby allowing the curtain40to be less shaken by external impact.

The cord line50has one end fixed to the rotating bar10to thereby be wound or unwound according to the rotation of the rotating bar10and has the other end passing between the weft44and the reinforcing weft46and then fixed to the lower end of the curtain. That is, a space is formed between the reinforcing wefts46woven together with the curtain40at the time of weaving the curtain60and the wefts44without a separate ring or hole and the cord line50passes through the space as shown inFIGS. 4 and 5, such that the roman shade according to the present invention is implemented. However, it is preferable that a material of the cord line50is nylon66. The reason is that a surface of the nylon66is not rough, such that the nylon66easily passes through textiles having a narrow gap without being caught by the textiles and has high strength.

Meanwhile, the number of layers formed when the roman shade is folded is determined according to the number of reinforcing wefts46through which the cord line50passes. When one end of the cord line50is wound around the rotating bar10by the rotation of the rotating bar10, the lower end of the curtain40connected to the other end of the cord line is raised. When the lower end of the curtain40is continuously raised, the lower end of the curtain40contacts the reinforcing weft46through which the cord line50passes to form the layer. Likewise, the reinforcing weft46contacting the lower end of the curtain40and another reinforcing weft46positioned on the reinforcing weft46and having the cord line50passing therethrough contact each other to form a layer. When the above-mentioned process is repeated up to a reinforcing weft46positioned at the uppermost portion, layers having the number corresponding to that of woven reinforcing wefts as shown inFIGS. 11B and 13Bare formed.

In addition, a plurality of cord lines50may be installed in a length direction of the reinforcing weft46. It is preferable that the cord lines50are formed to be horizontally symmetrical to each other, having a predetermined interval therebetween. This is to allow the curtain40to be stably folded or unfolded.

In the roman shade according to the present invention, since the reinforcing wefts46are woven without forming a separate ring or hole and the cord lines50may pass between the wefts44and the reinforcing wefts46, when the curtain40is woven, a separate setting or design is not required. Further, in the case in which the cord lines50are further installed after the curtain40is woven, it is only required to pass the cord lines50between the woven reinforcing wefts46and the wefts44without installing an additional ring or hole.

Hereinafter, second and third exemplary embodiments of a roman shade curtain and a roman shade according to the present embodiments will be described.

FIG. 6is a front view showing a second exemplary embodiment of a roman shade according to the present invention;FIG. 7is a partially enlarged view showing a second exemplary embodiment of a roman shade according to the present invention;FIG. 8is a partial side cross-sectional view showing a second exemplary embodiment of a roman shade curtain according to the present invention;FIG. 9is a front view showing a third exemplary embodiment of a roman shade according to the present invention; andFIG. 10is a partially enlarged view showing a third exemplary embodiment of a roman shade according to the present invention.

The roman shade curtain according to the present invention is configured to include a curtain40woven by interweaving warps42and wefts44with each other and including reinforcing warps48interweaved with the wefts44; and cord lines50passing between the warps42and the reinforcing warps48and then fixed to a lower end of the curtain40.

In addition, the roman shade according to the present invention is configured to include a rotating bar10; a frame having a shaft of both ends of the rotating bar10connected to both ends of an inner side thereof; a traction line30installed at one end of the rotating bar10to adjust rotation of the rotating bar10; the curtain40woven by interweaving the warps42and the wefts44with each other, having an upper end connected to the frame20, and including the reinforcing warps48interweaved with the wefts44; and the cord lines50having one end fixed to the rotating bar10and the other end passing between the warps42and the reinforcing warps48and then fixed to the lower end of the curtain40.

Since the rotating bar10, the frame20, the traction line30, and the like, are the same as the rotating bar10, the frame20, the traction line30, and the like, described above, a description thereof will be omitted.

First, the second exemplary embodiment of a roman shade according to the present invention will be described. In the second exemplary embodiment of the roman shade, the reinforcing warps48are vertically disposed instead of the reinforcing wefts46and are interwoven with the wefts44as shown inFIG. 6. The reinforcing warps48are also components woven integrally with the curtain40at the time of weaving the curtain40since they are placed over the warps42and are interwoven with the wefts44and allowing cord lines50to be described below to pass therethrough. The cord lines50pass between the warps42and the reinforcing warps48as shown inFIG. 8. Unlike the reinforcing wefts46, even though the number of reinforcing warps48formed vertically is only one, the number of layers formed in the curtain40may be adjusted to be plural. Referring toFIG. 7, the cord line50descends at the left based on a single reinforcing warp48, passes between the reinforcing warp48and the warp42, moves to the right, and then descends. Likewise, since the cord line50is connected to the curtain40while repeating a process in which the cord line50passes from the right to the left and from the left to the right, even though only one reinforcing warp48is formed, a plurality of layers may be formed.

However, the number of reinforcing warps48may also be plural. This is to additionally form the cord lines50so as to correspond to the additionally formed reinforcing warps48, thereby allowing the curtain40to be stably folded or unfolded.

Meanwhile, in the third exemplary embodiment of the roman shade according to the present invention, the reinforcing warps48are formed in a length direction of the weft44, that is, in a horizontal direction. As shown inFIG. 9, the reinforcing warps48are formed in a horizontal direction of the curtain40. Similar to the second exemplary embodiment, in the third exemplary embodiment, the reinforcing warps48are placed over the warps42and are interwoven with the wefts44, such that they are woven integrally with the curtain40at the time of weaving the curtain40, and the cord line50passes from the left to the right and from the right to the left between the reinforcing warp48and the warp42, as shown inFIG. 10. However, unlike the second exemplary embodiment, in the third exemplary embodiment, the reinforcing warp48is horizontally woven, thereby making it possible to accomplish an effect similar to that of the first exemplary embodiment, that is, to allow a plurality of cord lines50to penetrate through a single reinforcing warp48.

Meanwhile, in the third exemplary embodiment, a plurality of reinforcing warps48are formed according to the warps42, the number of cord lines50that may penetrate through the reinforcing warps48is determined according to the number of reinforcing warps48, and layers having the number corresponding to the number of cord lines50penetrating through the reinforcing warps48are formed when the curtain is folded.

Hereinafter, additional components of the roman shade according to the present invention will be described.

FIGS. 11A and 11Bare views showing an operation state of an interval maintaining member of the roman shade according to the present invention;FIG. 12is a perspective view showing a fixing bead of the roman shade according to the present invention; andFIGS. 13A and 13Bare views showing operation states of the interval maintaining member and the fixing bead of the roman shade according to the present invention.

The interval maintaining members52, which include a slit51formed at a side thereof and have a cylindrical shape, are installed on the cord lines50as shown inFIG. 11Ato allow the layers to be formed at predetermined intervals when the curtain40is folded. The interval maintaining members52are present on the cord lines50between the reinforcing wefts46when the layers are formed, such that the reinforcing wefts46do not directly contact each other, but have the interval maintaining member52positioned therebetween, thereby making it possible to allow a predetermined interval to be maintained. Therefore, as shown inFIG. 11B, when the curtain40is folded, the interval maintaining members52allow the layers to be formed, having predetermined intervals therebetween, when the curtain40is folded.

The fixing beads54, which include a through-hole formed therein and have a bead shape, are not fixed to the rotation bar10, but are fixed to auxiliary cord lines50afixed to upper and lower ends of the curtain40, as shown inFIG. 12. Therefore, when the curtain40is unfolded, the fixing beads54fixed to the auxiliary cord lines50aare caught by the reinforcing wefts46, such that the curtain40is no longer unfolded and the layers are formed.

Meanwhile, the roman shade according to the present invention in which the fixing beads54are formed may further include interval maintaining members52. Referring to FIG.

13A, when the curtain40is unfolded, the curtain40is not completely unfolded by the fixing beads54, but forms the layers. On the other hand, when the curtain40is folded, the layers are formed at predetermined intervals in the curtain40by the interval maintaining member52, as shown inFIG. 13B.

The roman shade curtain and the roman shade using the same according to the exemplary embodiments of the present invention are integrally woven without forming a separate ring, are woven by a simple process, and have excellent durability.
