The connecting plate 121 is pulled by the elastic force of the coil spring 124, thereby elastically preventing lateral movement of the slat support member 8 located at the other end 9 b toward the one end 9 a beyond a certain level. Yes.

  The closing plate 141 stands on the vertical frame 14a in order to close a gap generated between the slat 9 located at the other end 9b and the vertical frame 14a in the fully closed state of the opening P (the state shown in FIG. 13). It is installed.

  In the vertical blind device 1 described above, in the open state of the opening P, the protrusion 101 is disposed in the guide passage 19, and the strips 21 and 25 are bent as shown in FIG. As shown in FIG. 11, they are closely polymerized (bundled) on the other end 9b side. When the opening P is closed by traveling the chain 52 in the A direction when the ball chain 71 is manually moved, the slat support member 8 positioned at the one end 9a is first moved in the lateral direction H toward the one end 9a. The belt-like bodies 21 and 25 of the link mechanisms 4 and 5 are stretched tightly by the movement in the lateral direction H toward the one end 9a of the slat support member 8 located at the one end 9a. The slat support member 8 following the slat support member 8 to be moved starts to move in the lateral direction H toward the one end 9a, and the subsequent slat support members 8 sequentially move in the lateral direction H toward the one end 9a in the same manner. At the same time, the slats 9 are sequentially moved in the lateral direction H toward the one end 9a, and the protrusion 101 is guided by the guide passage 19 in the lateral direction H toward the one end 9a. When moving, as a result of the slat 9 being held in a tilted state substantially perpendicular to the lateral direction H, the opening P is closed like a bowl with the slat 9, as shown in FIGS. The

  Further, when the chain 52 is run in the A direction, the belt-like bodies 21 and 25 extend immediately before the opening P is completely closed, while the slat support member 8 located at the other end 9b via the belt-like bodies 21 and 25 is coiled. The slat located at one end 9 a is moved slightly in the lateral direction H toward the one end 9 a against the elastic force of the spring 124, and the protrusion 101 faces the guide recess 102 and comes into contact with the cam member 103. The support member 8 starts to rotate in the R1 direction, and the end portion 32 of the belt-like body 25 is moved in the lateral direction H toward the one end 9a with respect to the end portion 28 of the belt-like body 21, thereby The slat 9 positioned at the one end 9a is rotated in the R1 direction, and the slat support member 8 positioned at the one end 9a is rotated via the band-shaped body 21 and the band-shaped body 25 to the slat support member 8 on the other end 9b side. Communicated to Results All of the slat supporting members 8 and slats 9 are held substantially tilted state in the lateral direction H, as shown in FIGS. 13 and 14, the opening P by the slats 9 will be fully closed.

  When the opening P is opened, the ball chain 71 is manually moved in the reverse direction, whereby the protrusion 101 is guided from the guide recess 102 to the guide passage 19, and the other of the slat support members 8 positioned at one end 9a. With the movement in the lateral direction H toward the end 9b, the belt-like bodies 21 and 25 are sequentially bent from the other end 9b side.

  In the vertical blind device 1 described above, since the moving mechanism 10 moves the slat 9 in the lateral direction H via the slat support member 8 located at one end 9a, as shown in FIG. When the part P is fully opened, the bundle of slats 9 can be arranged on the other end 9b side of the opening P. As a result, the opening P can be opened without being disturbed by the slats 9, and when the opening P is opened, A feeling of opening can be sufficiently obtained, and the link mechanisms 4 and 5 are fixed to the flexible belts 21 and 25 and the belts 21 and 25 at a predetermined interval and the belts 21 and 25. Thus, since the plurality of shaft members 23 and 26 connected to each other are provided, the assembly and maintenance of the link mechanisms 4 and 5 are simplified, and the strips 21 and 25 and the plurality of shaft members 23 and 26 To obtain reduced in weight by preparing a synthetic resin or the like, no longer require much greater force to move in the lateral direction H of the slats 9.

  According to the vertical blind device 1, the arm portion 31 has one end portion and the other end portion of the through hole 30 into which the shaft portion 47 of one end portion of the shaft members 23 and 26 of the link mechanisms 4 and 5 is rotatably inserted. The arm portion 35 has a through hole 34 into which the shaft portion 47 of the other end portion of the shaft members 23 and 26 of the link mechanisms 4 and 5 is rotatably inserted. Moreover, the arm portions 31 and 35 are coupled to each other via the fitting means 40 so that the corresponding through holes 30 and 34 of the one end portion and the other end portion of the arm portions 31 and 35 are coaxial with each other. Therefore, the shaft members 23 and 26 of the link mechanisms 4 and 5 can be supported rotatably by both ends, and smooth rotation of the shaft members 23 and 26 can be guaranteed. Even if the flexible strips 21 and 25 are used, The shaped body 21 and 25 is easily extended, it can be bent, it is possible to smoothly perform the movement in the horizontal direction H of the slats 9, and Thus, it is possible to properly support the slats 9.

  According to the vertical blind device 1, when the opening P is completely closed, the gap generated on the other end 9 b side with respect to the slat 9 positioned on the other end 9 b can be closed with the closing plate 141. Intrusion of rainwater and the like can be prevented, and a more complete opening P can be completely closed.

  According to the vertical blind device 1, the engagement of the claw portion 48 with the tube portion 43 in the fitting opening 41 is performed by a snap-fit method using the elastic deflection of the protrusion main body 45. In addition, the support 22 and the support 42 can be easily coupled to each other via the fitting means 40, and the slat support member 8 can be assembled and maintained in a short time.

In this case, in addition to the sprocket wheel 84, another sprocket wheel is arranged, and both sprocket wheels are arranged. An endless chain may be provided between them, and the blocking mechanism 57 can be omitted when such an endless chain is used. In addition, a timing belt or the like may be used instead of the chain 52, and when a timing belt is used, a toothed pulley may be used instead of the sprocket wheel 84.

  Further, in the above, the hollow rectangular tube portion 43 having the fitting opening 41 is integrally formed on the other surface of the arm portion 31, and the engaging protrusion 44 is integrally formed on one surface of the arm portion 35. However, instead of this, a hollow rectangular tube portion 43 having a fitting opening 41 on one surface of the arm portion 35 is integrally formed, and the arm portion 31 The fitting means 40 may be configured by integrally forming an engaging protrusion 44 that engages with the cylinder portion 43 in the fitting opening 41 on the other surface.

  Furthermore, in the above, the fitting means 40 is configured with a pair of engaging projections 44 that engage with the cylindrical portion 43 in each of the pair of fitting openings 41, but instead, as shown in FIG. One engagement protrusion 152 that is integrally formed on one surface of the arm portion 35 and that engages with the cylindrical portion 43 in one fitting opening 151, and is arranged with the engagement protrusion 152 interposed therebetween. The fitting means 40 may be configured to include a pair of fitting projections 153 fitted into the cylindrical portion 43, and in this case, the engaging projection 152 is inserted into the cylindrical portion 43. The projection main body 155 has a claw portion 156 that is integrally formed at the tip of the projection main body 155 and that engages with the cylindrical portion 43 in the fitting opening 151. The engagement of the fitting opening 151 of the 156 to the cylindrical portion 43 is the projection And the like are performed with a snap-fit that utilizes 155 the elastic deflection of.
