The trailing edge portion 35 of the blade 4 abuts against the leading edge 28 of the adjacent blade 4, respectively, and is elongated to form a leading edge link row front edge connecting member 73 and 74 and a trailing edge connecting rod trailing edge connecting rod The members 83 and 84, the blade supporting member 141 is lowered by the load of the plurality of blades 4 and the link mechanism 5, and is disposed at a position abutting against the abutting surface 153, and the straight-moving member 161 is disposed in the up-down direction Z of the straight-line arrangement. The highest position in the position.

Next, the operation of closing the opening 3 of the louver device 1 of the present embodiment will be described in detail with reference to the drawings.

First, in the louver device 1 in the open state shown in FIG. 3, the electric motor 106 is actuated to rotate the rotary shaft 105 in the r1 direction, and the chain 101 is moved in the direction A via the sprocket 104. By the movement of the chain 101 in the A direction, the lowermost blade 4b connected to one end 98 of the chain 101 via the connecting mechanism 102 and the plurality of blades 4 connected to the blade 4b via the link mechanism 5 are lowered, and plural While the blade 4 is being lowered, the blade supporting member 141 is lowered until the blade supporting member 141 abuts against the abutting surface 153 to restrict the lowering thereof. The rotation of the rotary shaft 105 in the r1 direction gives the coil spring 212 a rotational force in the r1 direction. However, as shown in FIG. 3, since the latch member 221 is engaged with the pin 219, the coil spring 212 does not rotate in the r1 direction but only The slewing body 211 is slid, and the straight slidable member 161 is biased upward by the transmission mechanism 163, but does not move upward. The trailing edge portion 35 of the blade 4a does not move in the vertical direction Z. As described above, since the blade supporting member 141 is simultaneously lowered with the plurality of blades 4, the center of gravity 39 of the blade 4a is also lowered while moving rearward with respect to the front-rear direction Y. By the lowering, the center of gravity 39 and the trailing edge of the blade 4a are lowered. 35 is relatively displaced in the vertical direction Z, and as a result, the blade 4a is tilted in the R1 direction. The tilting of the blade 4a caused by the lowering of the blade supporting member 141 is stopped by the abutment of the abutting surface 153 of the blade supporting member 141.

One of the uppermost one of the blade 4a supported by the blade supporting member 141 supported by the blade supporting member 141 which is lowered above the specific position by the abutment of the abutting surface 153 is connected to the blade 4 below the blade 4a. The link members 73 and 74 and the uppermost one of the pair of trailing edge link members 83 and 84 are further elongated by the plurality of blades 4 below the uppermost blade 4a, and the leading edge link member 73 and 74 and a plurality of pair of front edge link members 73 and 74 and a pair of trailing edge link members 83 and 84 below the trailing edge link members 83 and 84 are also elongated in order, thereby being as shown in FIG. As shown, the overlapping of the plurality of blades 4 is sequentially released from the upper blade 4.

As shown in FIG. 18, when all of the pair of leading edge link members 73 and 74 and the pair of trailing edge link members 83 and 84 are elongated, the protrusion 223 is raised by the movement of the chain 101 in the A direction. It abuts against the abutting surface 233 of the latch member 221 . When the projection 223 that abuts against the abutting surface 233 is further raised by the movement of the chain 101 in the A direction, the abutting surface 233 is pressed in the D direction, and the latch member 221 is rotated, and by this rotation, as shown in FIG. 18 As shown in the figure, the state in which the latch member 221 is caught by the pin 219 is released, and the prohibition of the straight-up free member 161 from being straight upward is released. By the rotation of the rotary shaft 105 in the r1 direction, the upward straight line force transmitted to the straight free member 161 via the slide mechanism 199 and the rack and pinion mechanism 201 is released, and the straight forward free member 161 is released from the upper and lower directions. The direction Z is straight upward, and by the straight line, a relative displacement to the upper and lower directions Z of the blade supporting member 141 is generated in the straight free member 161, by which the straight free member 161 is disposed above the blade supporting member 141. Thereby, the blade 4a also tilts in the direction of R1.

As described above, in the case where one of the pair of leading edge link members 73 and 74 and the pair of trailing edge link members 83 and 84 are elongated, if the chain 101 is further moved in the direction A, the connecting mechanism 102 The mounting body 116 is further lowered toward the lowermost blade 4b, and the connecting arm 120 is rotated in the F direction, and the blade 4b is moved rearward in the front-rear direction Y by the rotation. Further, in this example, the straight-line free-running member 161 based on the straight-line prohibition of the straight-line prohibiting mechanism 200 is rotated upward in the F direction and the F-direction of the connecting arm 120 is designed to start synchronously (especially from the one end 98 to the setting). There is a design of the length of the chain 101 of the other end 99 of the protrusion 223).

As shown in Fig. 19, if the link mechanism 102 is lowered at the lowermost position, the movement of the chain 101 in the A direction is stopped, and by the stop of the movement, the rotation of the link arm 120 in the F direction and the straight-moving member 161 are upward. The straight line ends. As described above, the louver device 1 is formed in an open state as shown in Figs. 19 and 22 .

By the movement of the chain 101 in the B direction, as shown in Fig. 20, the lowermost blade 4b connected to one end 98 of the chain 101 via the link mechanism 102 is raised. The rotation of the rotating shaft 105 in the r2 direction is transmitted to the straight-moving member 161 via the sliding mechanism 199 and the rack and pinion mechanism 201 as a straight-down force, and the straight-moving member 161 conveyed by the straight-moving force goes straight downward, and The blade supporting member 141 is relatively displaced, and as shown in FIG. 20, the uppermost blade 4a is tilted in the R2 direction, and the plurality of blades 4 below the blade 4a also convey the tilting force of the blade 4a via the link mechanism 5, whereby Similarly to the blade 4a, it tilts in the R2 direction. When the plurality of blades 4 are tilted in the R2 direction while moving in the B direction of the chain 101, the link arm 120 also rotates in the G direction opposite to the F direction, and the plurality of blades 4 are moved forward in the front-rear direction Y. After the connecting arm 120 is rotated by a certain amount in the G direction, the rotation is prevented by the abutment with the mounting body 116 of the blocking piece 121, so that the connecting arm 120 thus prevented is in a substantially horizontal state.

The member 184 abuts and is prohibited from going straight below the position.

As shown in Fig. 20, by the rise of the blade 4b based on the movement of the chain 101 in the B direction, the inclined plurality of blades 4 are sequentially superposed as described above, and when it is in the state shown in Fig. 21, the straight-moving member 161 is straight. The blade 4 rear edge portion 35 below the protruding portion 175 of the straight free member 161 is abutted and lifted, thereby being straight upward, and the uppermost blade 4a is tilted in the R1 direction based on the straight traveling member 161 straight ahead. The edge portion 33 abuts against the front edge portion 33 of the lower blade 4. During the straight-up direction of the straight-moving member 161, the sliding mechanism 199 generates a specific rotation load or more, and generates a sliding motion with respect to the rotating shaft 105, thereby forming the rotation of the rotating shaft 105 to be released to the straight-moving member 161. status. The blade supporting member 141 is raised by the blade 4 below the blade 4a. As described above, the louver device 1 is in the open state shown in Fig. 3.
