6, the width a of the mesh portion is 5 cm, the width of the first light-shielding portion b is 8.0 cm, and the width c of the second light-shielding portion is 5 cm, 21 cm, the upper part is matched with the first and third mesh parts and becomes the upper open lower shield mode in which the shield is open and the lower part is shielded. In some cases, the winding rods may be slightly rotated to partially align the first and third mesh portions to form the upper partial open mode.

(2) On the other hand, when the winding rods 330 are rotated more or less as shown in FIG. 5, that is, the upper first mesh portion 341a and the second light blocking portion 342b are matched, When the first shielding portion 341b and the second shielding portion 342a are matched with each other, the second mesh portion 342a is blocked by the second shielding portion 342b which is still wide, And the upper and lower cutoff modes in which the lower portion is also blocked can be used.

(3) On the other hand, the rotation of the winding rod 330 in the vertical cut-off mode is made more or less as shown in FIG. 4, that is, when the upper first mesh portion 341a and the third mesh portion 343a If the second mesh portion 342a is matched with the second mesh portion 342a, the upper and lower open modes in which the upper portion of the windshield is opened and the lower portion is opened are also possible.

However, in this case, the upper part is a structure in which 21 interception is repeated, and the lower part is a structure in which 5 cm opening and 21 cm interception are repeated. Also in some cases, the winding rods may be slightly rotated to partially or wholly match the first and third mesh portions so that the second mesh portions are partly matched to each other.

In this way, in the most developed state of the roll screen, i) according to the first prior art double-roll blind, only the two modes of opening the whole or closing the whole are possible (that is, , ii) Even with the double-roll blind according to the second conventional art of Fig. 2, only two modes of closing the upper open lower closure and the whole (that is, only the upper only can be adjusted in the closed state) , iii) According to the double roll blind according to the present invention, it is possible to have all three modes of opening the upper open lower closed and the full open as well as the whole (in other words, it is possible to adjust the whole in one body, Can be adjusted).

2, it is possible to adjust only the upper part in a state in which only the lower part is closed, considering that most of the privacy protection needs to be performed in the lower part of the second prior art of FIG. 2, In the second conventional technique, the roll blind can be completely rolled up when it is desired to open the entirety. However, in this case, the upper and lower portions can be opened entirely, and furthermore, the blind is driven for a long time, There was an inconvenience that it should be done. However, according to the present invention, if only 6.5 cm in the maximum expansion state (upper adjustment lower closure mode) of FIG. 6 is taken up, the state of FIG. 5 (full closed mode) State (full control mode) becomes possible.

Of course, there may be a case where the upper portion is closed and only the lower portion is intended to be opened. In this case, the screen can be achieved only by winding up and recommending only the middle portion. In this case, According to the present invention, there is an additional advantage that the upper portion can be adjusted to the partially opened state. Although the double-roll blind of the first prior art can of course be top-adjusted in the fully-closed state, the double-roll blind of the first prior art can not close the bottom only, It is possible to take all the advantages of the blind of the prior art 1 and the blind of the second prior art of Fig.

5, it is necessary to reel up to 6.5 cm in the fully expanded state, and the lower end of the anti-twisting member 350 having a weight is raised by about 3.25 cm. However, ~ 8 cm, so that even if the bottom of the screen rises about 3.25 cm from the doorway of the window, there is no problem to completely close the window.

As described above, the multifunctional double-roll blind having the roll screen of the present invention can use various roll screens as desired by a simple operation of the user with only one double roll blind, thereby satisfying the user's desire.

In the first embodiment shown in FIGS. 4 to 6, the lower closed upper open mode is realized in a state in which the roll screen is maximally deployed as shown in FIG. 6, and the upper closed upper closed state Mode, the entire closed mode of FIG. 5 is realized, and when the roll mode is further rewound by about 6.5 cm, the entire control mode of FIG. 4 is realized, while the winding mode of the roll screen is implemented in the opposite direction The second embodiment is also possible.

FIG. 7 is a perspective view showing the use state of the multifunctional dual roll blind having a roll screen according to another embodiment of the present invention, and FIG. 8 is a perspective view showing another use of the multifunctional dual roll blind having a roll screen according to another embodiment of the present invention 9 is a perspective view showing another use state of the multifunctional double roll blind having a roll screen according to another embodiment of the present invention.

In this embodiment, the entire control mode is implemented in a state in which the roll screen is maximally deployed as shown in FIG. 7, and when the roll screen is wound in the maximum deployment state (full control mode) of about 6.5 cm in FIG. 7, Mode is implemented, and the lower closed top open mode of FIG. 9 is implemented by further winding up by about 6.5 cm again, winding in the opposite direction to the first embodiment. A recommendation is made.

In the case of the first embodiment, it is preferable to complete sealing in that the lower portion is closed when fully expanded, whereas in the second embodiment, the screen has a symmetrical structure. Therefore, when cutting a long woven fabric to a required length There are advantages of being preferable.

In the above description, the roll screen is woven to have the mesh portion and the shielding portion. However, the mesh portion does not necessarily have to be a woven material having air permeability, and other transparent materials do not depart from the scope of the technical idea of the present invention, However, in the case of having air permeability, it is more preferable because it can exhibit not only mining and visibility but also ventilation purpose like inner and outer parts. In addition, when the mesh part and light shield part are integrally weaving, winding and winding are more natural and thin But it is not necessarily limited thereto.

That is, the present invention is not limited to the above-described embodiments and accompanying drawings, and various substitutions, modifications, and alterations can be made without departing from the technical idea of the present invention. Will be apparent to those of ordinary skill in the art.
