The upper and lower ends of the multiple blades 1 are rotatably supported by the support plate 6. Specifically, each of the upper and lower support plates 6 is composed of a single plate having a length extending over all the blades 1, and the upper and lower support plates 6 are formed with circular holes 7 at the attachment positions of the blades 1. The upper and lower circular shaft bodies 4 are fitted into the circular holes 7 of the upper and lower support plates 6 so that the square shaft bodies 5 protrude from the circular holes 7. One end of a flat plate-like link 8 is coupled to the square shaft body 5 protruding from the circular hole 7 of the upper support plate 6 among the upper and lower support plates 6. A square hole 8a that fits into the shaft body 5 is formed at one end of the link 8, and the washers 9a and 9b are fitted into the shaft body 5 that protrudes from the hole 8a with the hole 8a fitted into the shaft body 5. In this state, one end of the link 8 is coupled to the shaft body 5 by screwing the screw 10 into the female screw hole 5 a formed in the shaft body 5 from the end surface of the shaft body 5. One end of the link 8 is coupled to the shaft body 5 so that the attachment angle of the link 8 to each blade 1 is the same in all, and the other end of the link 8 is one continuous rod for all the links 8. 11 is pivotally connected by a screw 13 and a nut 14 with a washer 12 interposed. A handle 15 is attached to the shaft body 5 at the lower end of the blade 1 located in the center among the plurality of blades 1 by screws 16, and the blade 1 located in the center is rotated around the vertical axis by the handle 15. By doing so, all the blades 1 rotate in conjunction with each other via the rod 11 and the link 8.

A metal fitting 20 is attached to the lower end of the shaft body 5 having a square bottom shape via a spacer 19 with screws 16. The lifting prevention metal fitting 20 comes into contact with the lower surface of the protruding piece 21 formed horizontally in the lower frame 18 in order to divide the inner space of the lower frame 18 vertically. The link 8 attached to the shaft 5 at the upper end of each blade 1 and the rod 11 connecting all the links 8 are housed in the internal space of the upper frame 22 and formed on the support plate 6 that also serves as the lower plate portion of the upper frame 22. The shaft 5 having the square top shape of the blade 1 is inserted into the inner space of the upper frame 22 in a state where the shaft 4 having the circular top shape of the blade 1 is inserted into the hole 7 rotatably. It is coupled to the rod 11 via the link 8. A handle 15 is attached to the lower shaft body 5 of the blade 1 located at the center from the lower side of the lifting-preventing metal fitting 20, and the handle 15 is formed on the plate portion 23 on the front surface of the lower frame 18. The handle 15 projects forward from the narrow opening 24 so that the handle 15 can be operated outside the lower frame 18.

  With this configuration, by rotating the handle 15 counterclockwise by 90 degrees from the state in which each blade 1 is opened, the blade 1 located at the center directly connected to the handle 15 is also rotated by 90 degrees in the same direction. The other blades 1 are also rotated 90 degrees in the same direction via the link 8 and the rod 11, and all the blades 1 are closed simultaneously. When the closed blade 1 is opened, the handle 15 may be rotated 90 degrees clockwise.

  Next, the second embodiment shown in FIGS. 8 and 9 will be described. The link 8 used in the first embodiment has a flat plate shape, and the blade 1 is moved 90 by the handle 15. If it is attempted to rotate more than 90 degrees, the pivot part of the link 8 and the rod 11 hits the joint part of the link 8 and the shaft body 5 and cannot be rotated more than 90 degrees. In the second embodiment, however, The link 8 is formed so that the other end side has a step toward the outside as compared to the one end side, and the rod 11 is pivotally connected to the other end side having a step toward the outside as compared to the one end side. As a result, the rotation of the link 8 does not cause the pivotal portion of the link 8 and the rod 11 to hit the coupling portion of the link 8 and the shaft body 5, and the blade 1 is rotated 360 degrees by the handle operation. To get.

  In the two embodiments described above, all the blades 1 are connected to the upper end side of the blade 1, that is, one end side of the blade 1 via the link 8 and the rod 11.

The attachment angle of the link 25 to the blades 1 at both ends is different from the attachment angle of the link 8 coupled to the upper end of each blade 1, and is different by 90 degrees in the embodiment shown in the drawings. At the other end of the link 25 attached to the lower end of the blade 1 at both ends, both ends of one continuous rod 26 are pivotally connected by a screw 13 and a nut 14 with a washer 12 interposed. In the third embodiment, the lower end of the other blades 1 except for the blades 1 at both ends is brought into contact with the end face of the shaft body 5, and a screw 10 is inserted into the female screw hole 5 a formed in the shaft body 5. Is prevented from coming off from the lower support plate 6. Further, in the third embodiment, the washer 9 is brought into contact with the end surface of the shaft body 5 in a state where the square hole 8a at one end of the link 8 is fitted to the shaft body 5 protruding from the upper support plate 6. The screw 8 is screwed into a female screw hole 5 a formed in the shaft body 5 so that one end of the link 8 is coupled to the shaft body 5. The connection between the other end of the link 8 and the rod 11 is the same as in the first embodiment.

  Thus, the attachment angle of the link 8 that connects all the blades 1 on one end side of the blade 1 and the attachment angle of the link 25 that connects only the blades 1 on both ends on the other end side of the blade 1 are different. All the blades 1 can be completely synchronized and all the blades 1 can be rotated 360 degrees, that is, without rotating the handle 15 provided in the first embodiment. One blade 1, for example, the blade 1 located on one end side or the blade 1 located on the other end side may be rotated by hand.
