When the load increases, the portion wound around the disk 122 expands and slides with respect to the disk 122, causing the rotary shaft 85 to idle with respect to the pin member 117. When the rotational load of the rotary shaft 85 increases due to the contact of the pin member 117 with the fixing member 136 at the end portion 141 or 142 of the movement restricting hole 135, the idling mechanism and the rotation that rotate the rotary shaft 85 with respect to the pin member 117 are rotated. A sliding mechanism that idles the shaft 85 with respect to the pin member 117 is embodied by a coil spring 123.

  For example, as shown in FIGS. 2, 3, 13 and 14, the tilting mechanism 9 operates the electric motor 87 in a state where all the blades 6 are overlapped and bundled upward, and the sprocket wheel 79 is moved in the R4 direction. The rotation of the rotating shaft 85 in the R4 direction with a slight descent in the B direction of the support member 27a with respect to the lowest blade 6a based on the initial travel of the chain 77 by the rotation of the rotation of the coil 77 causes the coil spring 123 to move in the R4 direction via the disc 122. The pin member 117 is moved in the R4 direction at one end 124 of the coil spring 123 that is further rotated in the R4 direction after the support member 27a is slightly lowered in the B direction, and can be displaced by the movement of the pin member 117 in the R4 direction. The arm member 114 is pushed out to swing the support member 27b in the R1 direction, thereby lifting the rear edge link member 62 with respect to the front edge link member 61. On the other hand, the leading edge link member 61 is lowered with respect to the trailing edge link member 62, and the superposition is successively performed with the lowering of the support member 27a due to the synchronous traveling of the chain 77 accompanying the rotation of the sprocket wheel 79 in the R4 direction. The upper blade 6 to be released is tilted in the R1 direction, and the blade 6 is tilted in the R1 direction as shown in FIG. 16 until the end 141 of the movement restriction hole 135 contacts the annular portion 138 of the pin member 117. Then, the rotation of the rotary shaft 85 with respect to the pin member 117 due to the slip of the coil spring 123 with respect to the disc 122 due to the contact with the annular portion 138 on the end portion 141 side of the movement restricting hole 135 of the pin member 117. Thus, the further swinging of the support member 27b in the R1 direction is stopped. Thus, in the blind device 1, the R1 of the support member 27b is stopped. Even after the swinging of the direction is stopped, the chain 77 is continuously driven by the rotation of the sprocket wheel 79 based on the operation of the electric motor 87. As a result, the tilting mechanism 9 causes the trailing edge link member 62 to move relative to the leading edge link member 61. The lifted link mechanism 7 tilts the lower blades 6 that are released one after another, and as shown in FIG. Will be distributed.

  As shown in FIG. 16, when the electric motor 87 is operated in the reverse state with the blades 6 being tilted as shown in FIG. 16, the tilting mechanism 9 is applied to the lowest blade 6a in the initial travel of the chain 77 by the sprocket wheel 79. After the support member 27a is slightly raised in the A direction, the hole wall 129 contacts the tip end portion 130 of the pin member 117 by the rotation of the interposed member 128 in the R5 direction by pressing the other end 125 of the coil spring 123 against the hole wall 131. Then, the distal end portion 130 is pressed in the R5 direction, the pin member 117 is moved in the R5 direction, the movable arm member 114 is pulled in by the movement of the pin member 117 in the R4 direction, and the support member 27b is swung in the R2 direction. As a result, the trailing edge link member 62 is lowered with respect to the leading edge link member 61, while the leading edge link member 61 is lifted with respect to the trailing edge link member 62. After raising the blade 6 to cause the return tilt in the R2 direction and causing the blade 6 to return in the R2 direction until the end 142 of the movement restriction hole 135 contacts the annular portion 138 of the pin member 117. The rotation of the rotary shaft 85 with respect to the pin member 117 due to the sliding of the coil spring 123 with respect to the disc 122 due to the contact with the annular portion 138 on the end 142 side of the movement restricting hole 135 of the pin member 117 is supported. The return swing of the member 27b in the R2 direction is stopped. Even after the return swing of the support member 27b is stopped, the chain 77 is continuously driven by the sprocket wheel 79 by the operation of the electric motor 87. As the lowest blade 6a rises, it is overlapped from the lower blade 6 arranged substantially horizontally, and finally all are overlapped as shown in FIGS. 2, 3, 13 and 14. Blade 6 is arranged above the opening 5 while being bundled.

The other end guide passage 94 is covered with the lid portion 1 so that the other end 76 of the chain 77 guided and moved by the other end guide passage 94 is hidden and the other end 76 is not exposed to the opening 5. Because it is covered with 4 and has excellent aesthetics, and has a holding means 10, it is possible to hold a plurality of blades 6 hanging from the opening 5 so as not to be shaken by wind etc. In addition, the product life can be improved.

  Moreover, according to the blind device 1, as shown in FIG. 17, when the upper blade 6 is overlapped with the lower blade 6 in the two adjacent blades 6 with respect to the vertical direction, The flat surface 69 of the shaft support 66 associated with the lower blade 6 that contacts the lower end surface 68 of the shaft support 66 associated with the blade 6 gradually approaches the substantially central portion 44 of the lateral edge of the lower blade 6. As a result, the rotation direction of the shaft support portion 66 can be specified in the R3 direction so that the belt-like body 63 can be disposed between the two blades 6 superposed in the vertical direction. It is possible to eliminate the sag from the belt-like body 63 to the outside and to have an excellent aesthetic appearance, and since the shaft portion 67 of the shaft member 64 is mounted in the complete blockage receiving hole 42, Strong connection Can wings 6 can eliminate that hanging unsightly.

  Further, in the blind device 1, since the holding groove 34 has the inclined surfaces 45 and 46 in addition to the pair of parallel flat surfaces 47 extending in the A and B directions, the blade 6 can be moved without being obstructed by the protrusion 145. As shown in FIG. 19, the tilting mechanism 9 can be tilted to the maximum from the state substantially parallel to the horizontal direction shown in FIG. 18, and the blade 6 is tilted and lifted so as not to be shaken by wind or the like. Can be made.
