1 to 5, the present invention mainly includes a first unit 100, a second unit 200, a third unit 300, a fourth unit 400, a fifth unit 500, 6 units (600). Let's look at the specific configuration of each unit.

The first unit 100 includes a first tower 110 and a second tower 120 disposed at a distance from the first tower 110. The first tower 110 and the second tower 120 are disposed apart from each other with a large space such as a workplace or a car park. The first tower 110 and the second tower 120 may be formed of iron frames.

The second unit 200 includes a first shaft 210 accommodated in the first tower 110 and a second shaft 220 accommodated in the second tower 120 and disposed in parallel with the first shaft 210 .

Specifically, the second unit 200 includes a first main bearing 211, a first auxiliary bearing 212, a second main bearing 221, a second auxiliary bearing 222, a plurality of first spools 213, And a plurality of second spools 223.

The two first main bearings 211 are mounted on both ends of the first shaft 210 to rotate and support the first shaft 210.

The two second main bearings 221 are mounted on both ends of the second shaft 220 to rotate and support the second shaft 220.

The plurality of first spools 213 are mounted along the longitudinal direction of the first shaft 210 and rotate integrally with the first shaft 210. The first ends of the first spools 213 are fixed and each of the plurality of wires 310 is wound .

The plurality of second spools 223 are mounted along the longitudinal direction of the second shaft 220 to rotate integrally with the second shaft 220 and the second ends are fixed to wind each of the plurality of wires 320 .

A plurality of first auxiliary bearings 212 are additionally mounted along the first shaft 210 to rotatably support the first shaft 210 and a plurality of second auxiliary bearings 212 222 are further mounted to support the second shaft 220 in rotation.

The plurality of wires are specifically configured as follows.

A plurality of first wires 310 wound around a plurality of first spools 213 and a plurality of second wires 320 wound around each of a plurality of second spools 223, The ends of the first wires 310 and the ends of the plurality of second wires 320 are detachably coupled to each other. The first wire 310 and the second wire 320 are combined to move integrally with each other and the eyelashes 510 are coupled to the lower side of the first wire 310. When the coupled wires 310 and 320 move toward the first wire 310, the detachable shield 510 is folded and when the coupled wires 310 and 320 move toward the second wire 320, the detachable shield 510 is unfolded .

The second unit 200 includes a first pulley 111 installed at an upper portion of the first tower 110 and a second pulley 121 installed at an upper portion of the second tower 120.

The first pulley 111 supports the first wire 310 and keeps the first wire 310 tight and guides the first wire 310 to the first shaft 210 disposed in the lower portion of the first tower 110.

The second pulley 121 supports the second wire 320 and maintains the second wire 320 tightly and guides the second wire 320 toward the second shaft 220 disposed in the lower portion of the second tower 120.

The third unit 300 has a first end fixed to the first shaft 210 and a second end fixed to the second shaft 220 so as to be movable in the longitudinal direction of the first shaft 210 and the second shaft 220 And a plurality of wires 310 and 320 disposed parallel to each other.

Specifically, the third unit 300 includes a wire fixing supporter 330, an annular connecting member 340, and a ring-shaped engaging member 350.

The wire fixing supporter 330 is orthogonally coupled to the ends of the plurality of second wires 320 so that the operator can move the plurality of second wires 320 simultaneously. When the plurality of second wires 320 are composed of four wires, the wire fixing supporter 330 is orthogonally coupled to the four second wires 320.

When the operator holds the wire fixing supporter 330 to work, the four second wires 320 can be easily moved to the four first wires 310 at a time. Further, even when the coupling between the plurality of wires 310 and 320 is released even in the already coupled state, it is possible to easily release the coupling at once by holding the wire fixing supporter 330.

Without the wire fixture support 330, the operator would have to couple each of the second wires 320 to each of the first wires 310, which would be very time consuming and inconvenient. The wire fixing supporter 330 is preferably made of stainless steel or a plastic material.

The annular connecting members 340 are respectively formed at the ends of the plurality of second wires 320 and are detachably coupled to the ends of the plurality of first wires 310. Specifically, the second wire 320 may be coupled through the wire fixing support 330 or may be fixedly connected to the bottom or top surface of the wire fixing support 330 using a fixing member. The annular connecting member 340 is provided at the foremost position of the plurality of second wires 320.

The ring-shaped latching members 350 are respectively formed at the ends of the plurality of first wires 310 and detachably coupled to the annular connecting member 340 formed at the ends of the plurality of second wires 320.

The reason why the first wire 310 and the second wire 320 are detachably coupled is that if the wing 510 is unfolded and used almost as in the winter season, The first wire 310 may be wound and the second wire 320 may be loosened to fold the wing 510. In this case, however, the plurality of second wires 320 may be unfavorable because they are spread in the air . In this case, the annular connecting member 340 and the ring-shaped engaging member 350 are disengaged from each other and separated from each other between the first wire 310 and the second wire 320, 2 tower 120 and the first wire 310 and the clinging film 510 are stored in the first tower 110 to be neatly arranged.

The fourth unit 400 is connected to the first shaft 210 and the second shaft 220 to transmit a driving force rotating in the first direction or the second direction to the first shaft 210 and the second shaft 220 At the same time, the first end is rewound and the second end is rewound, so that the first end is rewound and the second end is rewound.

Here, it is assumed that the first direction is the right side (the first tower 110 direction) and the second direction is the left side (the second tower 120 direction). When the first shaft 210 and the second shaft 220 simultaneously rotate to the right, the ornamental film 510 is folded. When the first shaft 210 and the second shaft 220 simultaneously rotate to the left, Is unfolded.

Specifically, the fourth unit 400 includes a first motor 410 having a first driving shaft 411 disposed in parallel with the first shaft 210 and rotating in a first direction, And a first driven sprocket 414 mounted on the first shaft 210 and connected to the first driving sprocket 412 and the chain 413. The first driven sprocket 414 is coupled to the first driving sprocket 412,

The fourth unit 400 includes a second motor 420 having a second drive shaft 421 disposed in parallel with the second shaft 220 and rotating in the second direction, And a second driven sprocket 424 coupled to the second drive sprocket 422 and the chain 423 mounted on the second shaft 220. The second drive sprocket 422 is coupled to the second drive sprocket 422,

Since the fourth unit 400 needs to lower the rpm of the first and second motors 410 and 420 that rotate at a high speed to a desired level, the fourth unit 400 is provided in the first motor 410, And a second reduction gear 425 provided in the second motor 420 to reduce the rpm of the second drive shaft 421. The first reduction gear 415 reduces the rpm of the second drive shaft 421 and the second reduction gear 425 reduces the rpm of the second drive shaft 421. [

The fourth unit 400 simultaneously controls the first motor 410 and the second motor 420 when the wing 510 is opened so that the two motors simultaneously move in the second direction The two motors simultaneously control the first motor 410 and the second motor 420 in the first direction (right direction, the direction of the first tower 110) And a control unit 430 for controlling the rotation of the motor.

The fifth unit 500 has a predetermined width and is disposed at a predetermined height from the ground. One end of the fifth unit 500 is fixed to the first tower 110. When the second end is wound while the first end is wound, And an ornamental membrane 510 extending toward the second tower 120 side and folding toward the first tower 110 side when the first end is wound and the second end is unwinded.

3, a reinforcing member 520 is attached along the longitudinal direction at regular intervals, and a plurality of through holes 521 are formed in the place where the reinforcing member 520 is attached. The lower part of the sixth unit 600 is coupled to the plurality of through holes 521 and then the washer 510 is mounted by fastening the washer 621 and the nut 622.

The reinforcing member 520 is in the shape of a band attached on the wing 510 and is for reinforcing the corresponding portion of the wing 510 passing through the lower portion of the sixth unit 600 so as not to be torn easily.

The fifth unit 500 may further include a guide bar 530 mounted along the other edge of the shading film 510 and to which the ends of the plurality of first wires 310 are fixed.

Referring to FIGS. 4 and 5, the guide bar 530 is orthogonally coupled to the plurality of first wires 310. The first wire 310 may be coupled to the guide bar 530 or may be fixedly coupled to the bottom or top surface of the guide bar 530 using a fixing member.

A ring-shaped latching member 350 is provided at the front of the guide bar 530 to be detachably coupled to the annular linking member 340 formed at the ends of the plurality of second wires 320.

The guide bar 530 is fixed to the end of the first wire 310 so that when the first wire 310 is wound and the second wire 320 is unwound, the guide bar 530 is moved toward the first tower 110 side When the wing 510 is folded and the second wire 320 is wound and the first wire 310 is unwound, the guide bar 530 moves toward the second tower 120 while the wing 510 is folded .

A fixing portion 531 is protruded from the lower portion of the guide bar 530. The other end of the shielding film 510 is fastened to the fixing portion 531 using bolts 532 and nuts 533.

Finally, the sixth unit 600 guides the shuttle 510 through the lower portion of the washer 510 while moving on the plurality of wires 310 when the orifice 510 is folded or unfolded.

6, the sixth unit 600 includes an annular moving member 610 slidably moving on the first wire 310 when the wing 510 is folded or unfolded, And a protruding engaging portion 620 protruding from the lower portion of the moving member 610 to engage with the through hole 521 formed in the movable member 610.

The nut 612 and the washer 611 are deeply and sequentially engaged through the projecting engaging portion 620 formed at the lower portion of the annular moving member 610. Then, the protruding engaging portion 620 is inserted into the through hole 521 of the shading film 510. Then, the washer 621 and the nut 622 are coupled to the protruding engaging portion 620 in order.

6, washers 611 and 621 and nuts 612 and 622 are coupled to the bottom surface and the top surface of the washer 510 through the above-described coupling procedure. When the two nuts 612 and 622 are fastened tightly against the detachable shield 510 after the washers 611 and 621 are in turn engaged with the nuts 612 and 622, the detachable shield 510 and the annular moving member 610 are securely fastened .

The annular moving member 610 may be made of a smooth material such as SUS or zinc steel and may be formed by sliding the first wire 310 while the wires 310 and 320 move to the left or right, Left, and right directions.
