The mold bar 17 having a predetermined length is coupled to the upper end and the lower end of the blind 11, and the curved bar 17a, such as the outer diameter of the roll shaft 13 and 14, is curved to the mold bar 17. It is configured to maintain the unfolded state in the width direction of the blind 11 wound on the roll shaft (13) (14).

On the other hand, in the roll frame (15, 16) equipped with the operation winding means 100 and the elastic winding means 200 is provided with a cover (not shown) in some cases, the operation winding means 100 and the elastic winding means By covering the 200 is preferably configured to ensure the safety of the operation and the beauty of the appearance.

The action of the present invention bi-directional winding roll roll 10 configured as described above is as follows.

As shown in FIG. 3C, the rim driver 140 is pulled counterclockwise by pulling the operating line 150 while the blind 11 is wound on the lower roll shaft 14 by the elastic winding means 200. When rotated, the rotation protrusion 142 of the rotating rim drive 140 pushes the locking projection 131 of the locking spring 130 is tightened to the support boss 120 to the outside the lock spring 130 ) So as to be freely rotated at the support boss 120, and at the same time, the locking end of the driving shaft 110 in which the locking step jaw 112 is caught and fixed to the locking protrusion 131 of the lock spring 130. The jaw 112 is pushed to rotate the drive shaft 110.

In addition, the roll shaft 13 coupled to interlock with the drive shaft 110 during the operation is rotated counterclockwise to wind the upper portion of the connecting line 12 and the blind 11 in succession, and at the same time the lower roll shaft The blind 11 and the connecting cord 12 wound up at 14 are gradually released by tension, and the bidirectional winding roll blind 10 is in a state as shown in FIG. 3B or 3A.

In addition, the lower roll shaft 14 is rotated counterclockwise by the tension of the blind 11 and the connecting line 12 during the operation, the elastic rotating plate 210 coupled to interlock with the lower roll shaft 14 Pulls the elastic restoring spring 230 wound around the winding disc 220 to generate tension while winding on the outer circumference, thereby winding the connection line 12 and the blind 11 unwound on the lower roll shaft 14. It is prepared to be wound on the lower roll shaft 14 again.

After the operation line 150 is released, the lock spring 130 is fixed by being tightened to the support boss part 120 while being restored by the elastic force, and the tension of the blind 11 by the elastic winding means 200. The driving shaft 110 coupled with the upper roll shaft 13 which is to be rotated in the clockwise direction is caught by the locking stepped portion 112 while pushing the locking protrusion 131 of the lock spring 130 inwardly. Rotation of the drive shaft 110 caught in the lock spring 130 firmly fixed to the unit 120 is stopped to maintain the state after the position adjustment of the blind 11.

In addition, as shown in FIG. 3A, the rim drive body 140 is watched by pulling the operation line 150 in a state in which the wound 11 is wound on the upper roll shaft 13 by the operation winding means 100. When rotated in the direction, the rotating projection 142 of the rotating rim drive 140 is free to rotate in the support boss 120 while pushing the locking projection 131 of the locking spring 130 to the outside. At the same time, by pushing the engaging step portion 112 of the drive shaft 110 to rotate the drive shaft 110 in a clockwise direction, the blind 11 wound around the upper roll shaft 13 is released. .

In addition, the elastic restoration spring 230 wound on the elastic rotating plate 210 during the operation is returned to the winding disc 220, the lower roll shaft 14 is rotated in the clockwise direction by the elastic force wound, the rotating The lower roll shaft 14 is wound around the connecting line 12 and the blind 11 in order to maintain the unfolded state of the blind (11).

Then, when the operation line 150 is released, the locking spring 130 is fixed while being fastened to the support boss 120 as in the above operation, and the locking step 112 of the driving shaft 110 is fixed to the locking spring. By stopping the engaging projection 131 of 130, it is possible to maintain the state after adjusting the position of the blind (11).

On the other hand, when the upper roll shaft 13 is operated by electric movement is as follows.

When power is applied to the motor 170 and the drive shaft 171 of the motor 170 rotates clockwise or counterclockwise, the drive pulley 180 fixedly coupled to the drive shaft 171 is rotated, At the same time, the driven pulley 160 coupled to be interlocked by the driving pulley 180 and the belt 190 is rotated, and the rim driving body 140 fixedly coupled to the driven pulley 160 is rotated. Like the manual rotation of the upper roll shaft 13 using the operation line 150, the rim drive 140, the lock spring 130 and the drive shaft 110 are organically operated so that the drive shaft 110 is The upper roll shaft 13 is rotated while being wound to wind up or unwind the connecting line 12 and the blind 11.

At this time, the feed screw portion 172 integrally formed on the rotating drive shaft 110 is rotated, the cam nut 173 coupled to the feed screw portion 172 is conveyed in a straight line along the feed screw portion 172 and then limit The switch 174 is operated, and the limit switch 174 cuts off the power applied to the motor 170 to stop the driving shaft 171 to wind or unwind the blind 11 and the connecting line 12 for a certain period. The rotation of the transported upper roll shaft 13 is stopped, and when the driving shaft 171 of the motor 170 is stopped, the lock spring 130 is tightened and fixed to the support boss 120 as in the manual operation. The stop step 112 of the driving shaft 110 is stopped by the catching protrusion 131 of the lock spring 130 to maintain a state after adjusting the position of the blind 11.

When the bi-directional winding roll blinds of the present invention as described above are mounted on the window, the connecting string pulls the blind wound around the lower roll shaft in accordance with the rotation of the upper roll shaft using an operation line or a motor. It is configured to cover from the lower side to the upper side, so in the case of a private house using a corridor apartment or a fence as a wall of the room, the upper part of the window higher than the pedestrian's eye level is opened for ventilation, and the lower part of the window lower than the eye level of the pedestrian is blinded. By preventing the invasion of privacy from others and at the same time the upper portion of the window not covered by the blind is an effect of maintaining a more comfortable indoor environment by the inflow and ventilation of light.

In addition, when the operating line and the motor is operated so that the connecting line is completely wound on the upper roll shaft, and the blind wound around the lower roll shaft is released, covering both the lower side and the upper side of the window from the outside through the window. There is an effect that can completely block the influx of light.

In addition, when the upper part of the connecting line and the blind is partially wound on the upper roll shaft, the blind is partially opened upward from the lower direction of the window so that the range of light flowing into the room through the window is appropriately adjusted. There is an effect that can produce a variety of indoor atmosphere through lighting.
