Does not work. When the lower collar 22 of the lower panel body 20 is pulled up and folded, the restriction of the compression spring 35 is released, so that the louver blade 15 is quickly released by the urging force of the compression spring 35. For this reason, when folded to form a ridge, the louver blade 15 can be surely opened in the region surrounded by the casings 14 and 24.

  Further, by lowering the lower collar 22 of the lower panel body 20 to the stopper 58, the upper panel body 10 and the lower panel body 20 can be brought into a stretched state. It is possible to rotate the louver blade 15 by further driving the motor 51 and moving the pusher 37 relative to the relay plate 38 after the state 20 is extended. When the louver blade 15 is rotated to close the region surrounded by the casings 14 and 24, the pin 39 is at the upper end of the long hole 37b, or the screw 36 is at the lower end of the long hole 38a. By pushing down one arm 41a of the swinging member 41 most before contacting any of the members, the louver blade 15 is rotated, and the region surrounded by the casings 14 and 24 is closed. For this reason, it is possible to reliably close the region surrounded by the casings 14 and 24 by rotating with the louver blade 15. That is, it is possible to reliably expand the upper panel body 10 and the lower panel body 20 at the opening 2 and to reliably close the region surrounded by the casings 14 and 24.

  In addition, since the upper panel body 10 and the lower panel body 20 are restricted from moving in the expected direction by the shake preventing member 45 in a state where the upper panel body 10 and the lower panel body 20 are stretched, the opening 2 is opened. It is possible to provide a foldable panel unit 1 that is easily maintained in a closed state.

  In addition, when the lower panel 22 has been lowered, the operation member 44 that moves in conjunction with the raising / lowering operation of the drive chain 53 moves to the trigger member 34 where the projecting portion 34b is located on the trajectory. By further lowering the drive chain 53, the operation piece 44 comes into contact. For this reason, after the upper panel body 10 and the lower panel body 20 are in the extended state, the louver blade 15 regulates the rotation in the direction of opening the area surrounded by the casings 14 and 24. The upper panel body 10 and the lower panel body 20 are reliably expanded only by lowering the lower collar 22 of the lower panel body 20, and the inside of the region where each louver blade 15 is surrounded by the casings 14, 24. It is possible to make it not to rotate in the opening direction.

  In the above embodiment, the operation of the louver blade 15 is either the closed state or the open state. However, the present invention is not limited to this, and for example, the pusher 37 is lowered after the lowering of the lower collar 22 of the lower panel body 20 is stopped. By adjusting the distance or adjusting the position of the operation piece 44 relative to the interlocking rod 43, the louver blade 15 can be stopped at an arbitrary angle. In this case, even when the upper panel body 10 and the lower panel body 20 are stretched, it is possible to obtain daylighting. That is, in this embodiment, the pusher 37, the operation piece 44, and the like can be an angle restricting portion that restricts the opening angle of the louver blade 15.

  In the said embodiment, although the frame 5 was demonstrated as a different body from the foldable panel unit 1, it is good also as the foldable panel unit 1 including the frame 5. FIG. The foldable panel unit may be integrated with a fitting provided on the indoor side.

  Moreover, in the said embodiment, although the example in which the foldable panel unit 1 was provided with the opening window 3 was demonstrated, it is not restricted to this, For example, you may provide with the sliding window etc.

  In the above embodiment, the example in which the two panel bodies 10 and 20 are connected by the hinge 9 has been described. However, even if the number of panel bodies is three or more, it may be folded to form a fold. It doesn't matter.

  In the above embodiment, the example in which the compression spring 35 provided on the interlocking member 33 is not biased when the louver blade 15 is in the open state has been described. The region surrounded by 14 and 24 may be biased in the direction of opening.

  In the embodiment described above, the upper part of the two panel bodies 10 and 20 is the upper collar 11 and the upper shaft 11a of the upper panel body 10, and the lower part of the plurality of panel bodies is the lower collar 22 and the lower shaft 22a of the lower panel body 20. However, the present invention is not limited to this. For example, the upper part of the plurality of panel bodies is a part on the upper side of the upper panel body 10 such as the upper end side of the vertical panel 13 of the upper panel body 10, and the lower part of the lower panel body 20 is the lower end side of the vertical panel 23 It is good also as a site | part of the lower part side of the lower panel body 20.

  Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
