  • One end of the switch fork 42 is coupled to the first switch gear 21, and the other end is inserted into the inclined groove 411 of the switch block 41 to be inclined with the switch block 41. Therefore, when the switch block 41 moves in the y direction or the -y direction, the switch fork 42 and the first clutch gear 31 move in the -x direction or the x direction in parallel.
  • 6 and 7 are schematic operation diagrams for showing the operation of the roll blind of FIG.
  • Roll blind 1 is a roll screen 70 is wound around the winding rod 61 and the opening and closing operation, and the amount of light transmission is controlled by the friction rod 62. At this time, while the winding rod 61 is operating, the control rod 43 does not rotate because power transmission is blocked.
  • the roll screen 70 wound around the winding rod 61 extends down via the friction rod 62 and is in contact with the friction rod 62 for a predetermined area, so that when the roll screen 70 is opened and closed, the friction rod ( 62 also rotates together. That is, the friction rod 62 is a structure driven by the rotation of the winding rod 61.
  • the friction rod 62 includes a friction layer 622 attached to at least a portion of an inner support rod 621 and an outer circumferential surface of the support rod 621.
  • the support rod 621 is a portion that supports the friction rod 62 to maintain rigidity
  • the friction layer 622 is a portion that contacts the roll screen 70 to provide friction or adhesion.
  • the friction layer 622 may be formed of a soft material having a high coefficient of friction, such as rubber or silicon, or may be formed of a material having an adhesive force, such as an adhesive tape, or a material having a mechanical bonding force, such as Velcro. That is, the friction layer 622 may be any material as long as the material has a friction force enough to push up the roll screen 70.
  • the roll screen 70 is the gap between the first screen 71 and the second screen 72 is minimized and the light transmission portion 73 is arranged in the vertical direction, the amount of light transmission is reduced.
  • the first screen 71 and the second screen 72 may be in close contact with each other to operate as one fabric.
  • the friction rod 62 pulls up the first screen 71
  • the first screen 71 and the second screen 72 are shifted from each other, and the blocking portion 73 is gradually horizontal. Keep the direction. While the blocking portion 73 maintains the horizontal direction, the distance between the first screen 71 and the second screen 72 increases so that the side surface of the roll screen 70 maintains a ladder shape.
  • the first screen 71 pulled up by the friction rod 62 is held in a stretched form between the winding rod 61 and the friction rod 62.
  • FIG. 8 is a view for explaining the opening and closing operation of the roll blind of Figure 1
  • Figure 9 is a perspective view for explaining the operation of the main components in the operating state of Figure 8
  • FIG. 12 is a perspective view illustrating an operation of main components in an operating state of FIG. 11, and FIG. It is sectional drawing cut
  • FIG. 14 is a figure for demonstrating the process which switches to the opening / closing operation
  • the roll screen 70 is opened and closed in the up / down direction, the winding rod 61 and the switch gear 21 is rotated together.
  • the switch gear 21 and the switch block 41 are engaged with each other, but are in inclined contact with each other. Therefore, if an external force for bringing the switch block 41 into close contact with the switch gear 21 is not applied, the switch block 41 can be easily detached by the rotational force of the switch gear 21. That is, when the switch gear 21 and the switch block 41 make oblique contact with each other and the switch gear 21 rotates, the switch block 41 is pushed while the switch gear 21 moves along the inclined surface. Sliding toward 45 is moved.
  • the switch block 41 rotates the control rod 43 by pushing the push protrusion 45 of the control rod 43 while slidingly moving in the y direction.
  • the control rod 43 is maintained while the pressing projection 45 is arranged in a direction perpendicular to the sliding direction of the switch block 41, the pressing projection 45 interferes with the sliding movement of the switch block 41. You will not receive.
  • the light emission amount of the roll screen 70 may be adjusted using the control rod 43 in a state in which the roll screen 70 is closed at a constant height.
  • the switch block 41 When the switch block 41 is engaged with the switch gear 21 by moving in the -y direction in parallel to the switch gear 21, the rotation of the winding rod 61 which cooperates with the switch gear 21 is limited. In addition, the switch block 41 engages the first clutch gear 31 and the second clutch gear 32 by moving the switch fork 42 in the x direction.
  • Each of the first clutch gear 31 and the second clutch gear 32 includes a ratchet gear to form a one-way clutch that transmits power only in one direction. Therefore, when the control rod 43 rotates in the second rotation direction, the friction rod 62 does not rotate, and the light transmission amount of the roll blind 1 does not change.
  • the ball chain 25 may be operated again to limit the light emission amount of the roll screen 70.
  • the switch block 41 moves the switch fork 42 to separate the first clutch gear 31 from the second clutch gear 32.
  • the friction bar 62 is rotated freely from the engagement state with the control rod 43.
