  One end side of the connecting member 28 is pivotally supported on the rotation shaft 141 of each slat 14 and is connected to the slat 14 so as not to rotate, and the other end side is connected to the interlocking member 27 via a connecting pin 281. The connecting pin 281 of the connecting member 28 at the position of the driven gear 26 passes through the interlocking member 27 and is connected to the driven gear 26 at a position eccentric from the rotation shaft 141. Therefore, when the driven gear 26 is rotated via the main driving gear 243, the interlocking member 27 is driven up and down, the connecting member 28 is rotated, and the slat 14 connected to one end thereof is rotated. That is, the rotation operation of the operation dial 242 of the operation unit 21 is transmitted from the main drive gear 243 to the driven gear 26 and is transmitted from the driven gear 26 to each slat 14 via the interlocking member 27 and the connecting member 28. . The interlocking member 27 is formed with a pair of upper and lower cutouts 271 that open to the outdoor side corresponding to the positions of the slats 14, and the starting point of the rotation operation by the operation unit 21 (position in FIG. 9 described later). At the end point (the position in FIG. 11 described later), the rotary shaft 141 can be received in the notch 271. Furthermore, when the received rotation shaft 141 contacts the bottom of the notch 271, the rotation operation cannot be performed beyond the start point and the end point, that is, the rotation operation of the operation dial 242 is restricted.

Next, the operation of the opening / closing operation device 20 and the slat 14 will be described with reference to FIGS.
FIG. 9 shows the opening / closing operation device 20 when the slat 14 is fully closed, and FIG. 10 shows the opening / closing operation device 20 when the slat 14 is fully opened. Further, FIG. 6 described above shows the opening / closing operation device 20 in a light-shielding state in which the slats 14 are lowered toward the outdoor side, and FIG. 11 illustrates a light-transmitting state (shielding state) in which the slats 14 are directed toward the outdoor side. The opening / closing operation device 20 in FIG.

  First, as shown in FIG. 9, when the slat 14 is fully closed, the teeth on one end of the outer periphery of the driven gear 26 (the start point side and the lower right side in FIG. 9) mesh with the main driving gear 243. The connecting pin 281 is positioned upward and the interlocking member 27 is moved upward. In this fully closed state, the rotating shaft 141 enters the lower notch 271 of the pair of notches 271 of the interlocking member 27, and the bottom of the notch 271 and the rotating shaft 141 come into contact with each other. Further, the interlocking member 27 cannot be moved upward. Accordingly, the driven gear 26 cannot rotate counterclockwise from the state shown in FIG. 9, whereby the main driving gear 243 cannot rotate clockwise, and the downward rotation operation of the operation dial 242 is restricted. . In such a fully closed state, the end portions of the slats 14 adjacent to each other in the vertical direction overlap each other in the prospective direction, and the slats 14 partition the outdoor from the balcony, thereby blocking light, wind, line of sight, etc. from the outside. It is supposed to be.

  When the operation dial 242 is rotated upward (counterclockwise in FIG. 9) from the fully closed state as described above, the driven gear 26 rotates clockwise through the main driving gear 243. As the driven gear 26 rotates, the interlocking member 27 and the connecting pin 281 of the connecting member 28 move downward and toward the balcony. Further, as the connecting member 28 rotates, the slat 14 connected to one end side thereof (rotating shaft 141 side) rotates clockwise, and the slat 14 is lowered toward the outdoor side as shown in FIG. It is in a light shielding state that has an inclination and can block sunlight. In such a light-shielding state, a gap having an inclination rising from the outdoor side toward the balcony is formed between the slats 14 adjacent to each other in the vertical direction. The line of sight is blocked.

  By further rotating the operation dial 242 upward from the light shielding state as described above, the slat 14 is rotated clockwise through the main driving gear 243, the driven gear 26, the interlocking member 27, and the connecting member 28. As shown, the slat 14 is in a substantially horizontal fully open state. In such a fully open state, a gap from the outdoor side to the balcony is formed between the slats 14 adjacent to each other in the vertical direction, so that wind from the outside can be introduced into the balcony, and sunlight from above or from below The majority of the line of sight can be blocked.

When the operation dial 242 is further rotated upward from the fully opened state as described above, the slat 14 rises toward the outdoor side and has an inclination as shown in FIG. It becomes a translucent state (obscured state) that can block the line of sight from. In such a translucent state, a gap is formed between the slats 14 adjacent to each other on the upper and lower sides, and an inclination is lowered from the outdoor side toward the balcony, so that sunlight and wind from the outside can be introduced into the balcony. It has become.
In each of the above states, the movement of the driven gear 26, the interlocking member 27, and the connecting member 28 is restricted by operating the lock member 25 in the operation portion 21 to engage the lock gear 253 with the main drive gear 243, thereby controlling the slats. 14 can be locked. Further, by releasing the engagement between the lock gear 253 and the main drive gear 243, the operation dial 242 can be rotated as described above, and the slat 14 can be adjusted to an arbitrary angle. Further, by rotating the operation dial 242 in the direction opposite to that described above, the slat 14 can be opened and closed from the fully open state or the translucent state toward the fully closed state.

According to this embodiment, there are the following effects.
(1) That is, since the rotation of the operation dial 242 is restricted by the engagement of the lock gear 253 and the main driving gear 243 of the lock member 25, the surface of the operation dial 242 can be prevented from being damaged, and the distance between the gear teeth can be adjusted. The operation dial 242 can be restricted in rotation in units of rotation angles. Accordingly, the rotation lock angle of the slat 14 can be finely adjusted with a fine pitch according to the gear tooth interval, and the slat 14 can be locked with an angle according to the user's preference, thereby enhancing convenience. .

(2) Further, since the operation dial 242 of the operation member 24 and the operation knob 252 of the lock member 25 are provided so as to protrude in the same direction and can be operated from the balcony side, the operation dial 242 and the operation knob 252 are operated. This makes it easier for the user to see. Accordingly, the user can easily determine whether the lock member 25 is in the locked position or the unlocked position, and the operation dial 242 can be erroneously operated or rotated with the slat 14 in spite of being in the locked position. It is possible to prevent the slats 14 from rotating unintentionally due to wind or the like because they remain in the unlocked position.
