The transmission mechanism 135 includes a lost motion mechanism 142, as shown in FIG. 4, and one end portion 115 of the mechanism 142 is disposed on the side of the end surface 116 of one of the semi-cylindrical portions 114 defining one end of the slit 113, and the other end portion 117 is disposed to define The other end of the slit 113 is on the other end surface 118 side of the semi-cylindrical portion 114, and the mechanism 142 is constituted by a coil spring 119 which is rolled up by frictional contact on the central shaft portion 111 of the pulley 86, and the idle mechanism 142 includes slippage. a mechanism that slides when the pulley 86 is rotated in a direction to release the strip 44 One end portion 115 of the coil spring 119 is in contact with the end surface 116 of the semi-cylindrical portion 114 at the rotation of the coil spring 119 which is frictionally contacted on the central shaft portion 111 of the wheel 86 in the same direction, and the coil spring 119 is opposed to the central shaft portion 111. At the same time as the screwing, the semi-cylindrical portion 114 is rotated in the same direction, and when the pulley 86 is rotated in the direction of winding the strip 44, the coil spring which is frictionally contacted on the central shaft portion 111 of the pulley 86 and rolled up 119, in the same direction of rotation, the other end portion 117 of the coil spring 119 is brought into contact with the end surface 118 of the semi-cylindrical portion 114, and the half-cylindrical portion 114 is rotated in the same direction while the coil spring 119 is tightened to the central shaft portion 111. The rotation of the rotating shaft 87 is transmitted to the rotating body 129. On the other hand, when the end portions 140 and 141 of the guide hole 136 are in contact with the fixing plate 139 of the coupling pin member 127 and the rotational load of the rotating body 129 is increased, the frictional contact is made. Slippage occurs between the central shaft portion 111 of the pulley 86 and the coil spring 119, and the pulley 86 is slid and idling by the coil spring 119 against the rotating body 129, whereby the rotating shaft 87 is idly rotated with respect to the rotating body 129.

On the one hand, the swing mechanism 6 can rotate the rotary shaft 87 by rotating the rotary shaft 87 in a state where the blades 3 shown in Fig. 1 are all overlapped and stacked one on another, and the pulley 86 is rotated by the rotation of the rotary shaft 87. The coil spring 119 is frictionally contacted on the pulley 86 to rotate the rotor 129, and the rotation of the rotor 129 causes the coupling arm member 124 to rotate as shown in FIG. 10 via the coupling pin member 127 to rotate the coupling arm member 124 via The cantilever member 96 is freely rotated to swing the free rocking member 107 in the r direction, thereby causing the trailing edge connecting member 72 to be lifted up relative to the leading edge connecting member 71, and on the other hand to cause the leading edge connecting member 71 to be connected with respect to the trailing edge connecting member. 72 is lowered, together with the movement of the strip 44 in the direction B in the direction in which the strip 44 is pulled out synchronously from the pulley 86. At the same time as the movement of the holder 81 is lowered, the blade 3 above the overlapping one by one is swung in the R1 direction, and the blade 3 is swung in the R1 direction as shown in FIG. 11 until the end of the guide hole 136. After the connecting pin member 127 on the 141 contacts the fixing plate 139, the rocking of the rotating body 129 by the rotating shaft 87 stops the rocking of the free rocking member 107, and after the rocking of the free rocking member 107 is stopped, the electric motor 91 is also used. As a result of the operation continuing to pull the strip 44 out of the pulley 86, the swing mechanism 6 causes the attachment mechanism 4 which lifts the trailing edge connecting member 72 with respect to the leading edge connecting member 71 to cause the blade 3 which is released one by one to be released one by one. The swing is superimposed and released as shown in FIG. 11, and all the blades 3 are swung and placed on the entire window 2.

On the one hand, the swing mechanism 6 causes the electric motor 91 to perform the reverse operation as described above, as shown in Fig. 11, as shown in Fig. 10, by the reverse rotation of the link arm member 124. The reverse rocking of the free rocking member 107 causes the leading edge connecting member 71 to rise relative to the trailing edge connecting member 72, and on the other hand, the trailing edge connecting member 72 is lowered relative to the leading edge connecting member 71, causing the blade 3 to be opposite to the R1 direction. When the belt body 44 is wound in the A direction and the holder 81 is raised as the belt 44 is wound around the pulley 86, the blades 3 which are higher than the blade 3 below the one by one are reversed. After swinging, the end portion 140 of the guide hole 136 is connected to the fixing plate 139 by the pin member 127, and the swing of the blade 3 is released as shown in FIG. 2, and the freewheeling member is stopped by the rotation of the rotating shaft 87 against the rotating body 129. After the rocking of 107, and after the rocking of the free rocking member 107 is stopped, the strip body 44 is further wound around the pulley 86 by the action of the electric motor 91. As shown in Fig. 1, the blades 3 are all overlapped and Disposed on the window in the state of being bundled Above the household 2.

The holding device 7 includes a steel wire 65 which is relatively freely movable through a perforation 61 of the linear body holder 27 which is a lateral edge portion of the blade 3 and a lateral edge portion of the holder 81, and one end is passed through the holder 145 is fixed to the attachment member 82, and the other end is fixed to the floor 147 of the building via the holder 146 as a holding linear body extending in the vertical direction.

The louver device 1 is the same as the support member 23, the linear body holder 27, the connection mechanism 28, the connection mechanism 4, the elevating mechanism 5, the swing mechanism 6, and the holding device 7, except for the electric motor 91 and the reduction gear mechanism 92. Also provided on the other side of the blade body 21, the rotating shaft 87 extends to the blade body 21 in order to supply the rotational power to the other side of the blade body 21 such as the lateral edge portion 148 side and the swinging mechanism. On the other side of the lateral edge portion 148, the elevating mechanism and the swinging mechanism on the other side of the lateral edge portion 148 of the blade main body 21 and the elevating mechanism 5 and the swinging mechanism 6 on the side of the lateral edge portion 22 of one of the blade main bodies 21 are provided. Act in sync.

According to the louver device 1 described above, since the free rocking member 107 is coupled to the rotating device 95 via the freely rotatable cantilever member 96, the rotating device 95 can be disposed on the side of the free rocking member 107, so that the free rocking can be located The bundled plurality of blades 3 below the member 107 are disposed as far as possible on the ceiling side, and sufficient lighting is not prevented from obstructing the field of view of the window 2, and in the two blades 3 adjacent in the up and down direction, when the upper blade 3 is in the up and down direction When the upper blade 3 is overlapped, the upper end surface 76 of the shaft support portion 75 on the upper blade 3 contacts the upper surface 77 of the shaft support portion 75 on the lower blade 3 to be inclined to the lateral edge portion of the lower blade 3 The central part is slowly getting higher, therefore, The rotation direction of the shaft support portion 75 can be fixed in the R2 direction, and the strip-shaped body 73 can be disposed between the two blades 3 that overlap in the vertical direction. As a result, the strip-shaped body 73 can be prevented from falling outward from between the blades 3. Preferably, because the shaft portion 38 of the shaft member 36 is freely insertable and detachable from the insertion hole 39 via the slit 40, the blade 3 can be easily removed from the connection mechanism 4, and the blade 3 can be attached after being removed. As a result, not only the assembly and the disassembly property are good, but also the manufacturing cost can be reduced, and the cleaning can be easily performed. Further, the blade main body 21 and the support member 23 can be detachably attached via the connection mechanism 28, and therefore, the elongated blade main body The support member 23 and the support member 23 are easy to assemble and disassemble, so that not only the assembly and disassembly property are good but also the manufacturing cost can be reduced, and the cleaning can be easily performed.

Further, according to the above louver device 1, the inner circumferential surface 51 and the inclined surface 54 of the blade 3 defining the through-hole 45 can be arranged such that the strip-shaped body 44 is not bent when the blade 3 is maximally swung by the swing mechanism 6. Since the straight line extends, not only when the blade 3 is swung, but also the strip-shaped body 44 can be maintained in a straight line without being affected by the swing of the blade 3, and the blade 3 can be swung and lifted without being hindered by the strip-shaped body 44.

On the rotating body 170; a gear 174 that meshes with the gear 171 and is rotatably supported on the fixed plate 173 via the shaft member 172; and a gear 176 that is decelerated relative to the rotation of the gear 171, and Direct movement with freedom The rack 175 of the member 151 is engaged.

The rotating body 170 and the gear 171 fixed to the rotating body 170 are disposed concentrically with the rotating shaft 87. The rotating body 170 includes an annular portion 112 which is concentric with the pulley 86 and is disposed on the ring of the pulley 86 like the rotating body 129. The recessed portion 134 is rotatably rotatable and slidably contacts the central shaft portion 111 of the pulley 86 to which the rotating shaft 87 is fitted, and is rotatably mounted relative to the central shaft portion 111; and the semi-cylindrical portion 114 is integral with the annular portion 112.

The transmission mechanism 135 includes a idling mechanism 142 formed by a coil spring 119 that contacts the fixed pin member 165 of the free linear member 151 at the end portions 180 and 181 of the guide hole 161 to freely move the member 151 at C and D. When the direct acting load in the direction rises, the rotating shaft 87 of the turning power source 88 is idly rotated with respect to the rotating body 170 of the turning and linear motion converting mechanism 154, and the idle mechanism 142 is unwound toward the belt 44 on the one hand. When rotating, the coil spring 119 wound by the frictional contact on the central shaft portion 111 of the pulley 86 is in the same square The upward rotation causes the other end portion 117 of the coil spring 119 to contact the end surface 118 of the semi-cylindrical portion 114 to rotate the semi-cylindrical portion 114 in the same direction, and when the pulley 86 is turned toward the direction in which the strip 44 is wound The end portion 115 of the coil spring 119 is brought into contact with the end surface 116 of the semi-cylindrical portion 114 in the same direction as the coil spring 119 wound in frictional contact with the central shaft portion 111 of the pulley 86, and the semi-cylindrical portion 114 is similarly oriented. Rotating in the same direction, the rotation of the rotating shaft 87 is transmitted to the rotating body 129, and on the other hand, the sliding mechanism is provided to the fixed pin member 165 by the free linear member 151 on the end portions 180 and 181 of the guide hole 161. In the case where the direct acting load of the free-motion member 151 in the C and D directions is increased by contact, the center shaft portion 111 of the friction-contact pulley 86 and the coil spring 119 are caused to slip, and the pulley 86 is caused to pass through the coil. The spring 119 is idling with respect to the rotating body 170, whereby the rotating shaft 87 is idly rotated with respect to the rotating body 170 (refer to FIG. 4).

In the louver device 1 shown in Figs. 13 and 14, the swing mechanism 6 causes the electric motor 91 to operate and the rotary shaft 87 to be operated, for example, in a state in which the blades 3 shown in Fig. 1 are all overlapped and stacked one on top. Rotating, the pulley 86 is rotated by the rotation of the rotating shaft 87, and the rotating body 170 is rotated by the coil spring 119 which is frictionally contacted on the pulley 86, and the free moving member is made via the gears 171, 174 and 176 by the rotation of the rotating body 170. 151 moves in the direction of D to The free rocking member 107 is rocked in the r direction by the freely rotating cantilever member 96 by the movement of the linear motion member 151 in the D direction, whereby the trailing edge connecting member 72 is opposed to the leading edge connecting member on one side as shown in FIG. When the lift is raised, the leading edge connecting member 71 is lowered relative to the trailing edge connecting member 72, and the holder 81 is pulled out from the pulley 86 in synchronism with the movement of the strip-like body 44 in the B direction. When the upper blade 3 which is unfolded one by one is caused to swing in the R1 direction, the contact of the free linear member 151 on the end portion 181 of the guide hole 161 against the fixed pin member 165 causes the rotating shaft 87 to idle against the rotating body 170. While the rocking of the free rocking member 107 is stopped, and after the rocking of the free rocking member 107 is stopped, the strip body 44 is continuously pulled out by the pulley 86 by the action of the electric motor 91, and the trailing edge connecting member is caused by the swinging mechanism 6. 72, the lower blade 3 is undulated with respect to the connection mechanism 4 which is raised by the front edge connecting member 71, and the lower blade 3 is swung one by one, and the overlap is released as shown in Fig. 15, and all the blades 3 are oscillated and disposed on the entire window 2, aspect As shown in FIG. 15, when the electric motor 91 is operated in the opposite direction to the above, in the state in which all the blades 3 have been swung, the reverse swinging member 107 is moved in the C direction by the free linear member 151. When the leading edge connecting member 71 is lifted up relative to the trailing edge connecting member 72, the trailing edge connecting member 72 is lowered relative to the leading edge connecting member 71, and the strip body is produced by winding the pulley 86 with the strip 44. The holder 81 caused by the movement of the direction A in the A direction is raised, so that the blade 3 which is higher than the lower blade 3 which overlaps one by one is swung in the opposite direction, and the pair of free linear members 151 on the end portion 180 of the guide hole 161 The contact of the fixing pin member 165 causes the rotating shaft 87 to idle the rotating body 170 to stop the direct movement of the free moving member 151, and is in the free rocking member 107 After the swinging is stopped, the strip-shaped body 44 is continuously wound around the pulley 86 by the operation of the electric motor 91, and the vane 3 is placed above the window 2 in a state in which the vanes 3 are all overlapped as shown in Fig. 1 .

The above-described effects can also be obtained by the louver device 1 shown in FIGS. 13 and 14, and in the rotation and linear motion conversion mechanism 154, the rotation of the gear 176 with respect to the gear 171 is decelerated, so that the blade 3 can be made. The lifting is performed at a low speed, and the half opening of the window 2 by the blade 3 and the swinging angle of the blade 3 are precisely set.

However, in the holding device 7 of the above-described louver device 1, although the steel wire 65 is passed through the through hole 61 of the linear body holder 27, the linear body holder 27 may not be used to support the front edge portion of the member 23. The perforations 47 provided in the central portion 26 between the rear end portion 25 and the rear edge portion 25 serve as holding perforations. In this case, as shown in FIG. 16, the perforation 47 for holding is defined as follows: an inclined surface 191 of one of the support members 23, which is directed to the rear edge portion 25 of the support member 23 which becomes the trailing edge portion of the blade 3.
