A cam surface 133 provided on the main body 70 for defining the guide slit 131 and slidingly contacting the cam roller 123, and a cam surface 134 provided on the plate-like main body 70 for defining the guide slit 132 and slidingly contacting the cam roller 123. It is equipped with. The guide slit 132 is disposed closer to the cam roller guide portion 101 than the guide slit 131. The cam surfaces 133 and 134 are connected to each other via a curved surface 135, and the cam roller 123 is guided from the guide slit 131 to the guide slit 132 at a portion where the guide slit 131 and the guide slit 132 are continuous. A curved path that is bent so as to be able to shift from the slit 132 to the guide slit 131 is formed. The cam roller guide portions 101 and 121 are symmetric with respect to a virtual axis extending in the Y direction.

Z方向に伸びたカム面133は、Z方向に伸びた案内スリット131において羽根部材5にR方向の回転を生じさせないようにカムローラ123の直動自在部材12に対するZ方向に交差する方向(Y方向を含む)の移動を規制するようになっている。   The cam surface 133 extending in the Z direction intersects the Z direction with respect to the linearly movable member 12 of the cam roller 123 so as not to cause the blade member 5 to rotate in the R direction in the guide slit 131 extending in the Z direction (Y direction). (Including) is restricted.

Y方向に伸びたカム面134は、Y方向に伸びた案内スリット132において羽根部材5にR方向の回転を生じさせるようにカムローラ123の直動自在部材12に対するZ方向の移動を規制するようになっている。   The cam surface 134 extending in the Y direction restricts the movement of the cam roller 123 relative to the linearly movable member 12 in the Z direction so as to cause the blade member 5 to rotate in the R direction at the guide slit 132 extending in the Y direction. It has become.

以上の伝達手段15は、直動自在部材12のZ方向の直動において、案内スリット131に配されているカムローラ123の直動自在部材12に対するZ方向の相対的な移動を許容すると共に当該カムローラ123の直動自在部材12に対するZ方向に交差する方向(Y方向を含む)の相対的な移動をカム面133により規制して、直動自在部材12の直動を羽根部材5に伝達しない一方、直動自在部材12のZ方向の直動において、案内スリット132に配されているカムローラ123の直動自在部材12に対するY方向の相対的な移動を許容すると共に当該カムローラ123の直動自在部材12に対するZ方向の相対的な移動をカム面114により規制して、カムローラ123を直動自在部材12の直動と共にZ方向に移動させて、羽根部材5をR方向に回転させるように直動自在部材12の直動を羽根部材5に伝達するようになっている。   The above transmission means 15 allows the cam roller 123 arranged in the guide slit 131 to move relative to the linearly movable member 12 in the Z direction when the linearly movable member 12 moves linearly in the Z direction, and the cam roller. On the other hand, the relative movement of 123 in the direction (including the Y direction) intersecting the Z direction with respect to the linearly movable member 12 is restricted by the cam surface 133 and the linear motion of the linearly movable member 12 is not transmitted to the blade member 5. When the linearly movable member 12 is linearly moved in the Z direction, the cam roller 123 disposed in the guide slit 132 is allowed to move relative to the linearly movable member 12 in the Y direction, and the linearly movable member of the cam roller 123 is allowed to move. The relative movement in the Z direction with respect to 12 is restricted by the cam surface 114, and the cam roller 123 is moved in the Z direction together with the linear movement of the linearly movable member 12, and the blade The linear motion of the linearly movable member 12 is adapted to transmit to the blade member 5 so as to rotate the timber 5 in the R direction.

以下、羽根部材4及び5並びに従動羽根部材6、7、8及び9が図2に示すように開口完全開放位置に配されているルーバ装置1を動作させて開口3の下部の閉鎖(部分閉鎖)を行う場合について説明する。まず、図9に示すように、被係止部材76を操作により係止部材75から離反させることで禁止手段13による直動自在部材12のZ方向の直動の禁止を解除する。   Hereinafter, the louver device 1 in which the blade members 4 and 5 and the driven blade members 6, 7, 8 and 9 are arranged at the opening fully opened position as shown in FIG. ) Will be described. First, as shown in FIG. 9, by prohibiting the locked member 76 from the locking member 75 by operation, the prohibition of the linear movement of the linearly movable member 12 by the prohibiting means 13 in the Z direction is canceled.

次に、被係止部材76を操作により上方に向かってZ方向に移動させ、この移動と共に直動自在部材12を図2に示す位置から上方に向かってZ方向に直動させ、この直動により案内スリット112に配されているカムローラ103を直動自在部材12と共に上方に向かってZ方向に移動させ、この移動によりカムローラ103を羽根部材4の回転軸心Pの回りで旋回させて、羽根部材4の開口閉鎖位置に向かうR方向の回転を羽根部材5の回転に対して先行して開始し、開始後、直動自在部材12を更に上方に向かって直動させることで、図10及び図11に示すように、羽根部材4並びに羽根部材4と共に回転される従動羽根部材6及び7を開口閉鎖位置に向かってR方向に回転させて開口3の下部を漸次閉鎖し、その後、図12に示すように、開口3の下部を完全に閉鎖(部分閉鎖)する。図12に示す状態の羽根部材4に支持アーム102を介して設けられているカムローラ103は、案内スリット112から曲路を介して案内スリット111に既に移行されており、従って、羽根部材4の前記回転は終了し、従動羽根部材6及び7の前記回転もまた羽根部材4の回転の終了と共に終了する。   Next, the locked member 76 is moved upward in the Z direction by operation, and along with this movement, the linearly movable member 12 is linearly moved upward in the Z direction from the position shown in FIG. The cam roller 103 disposed in the guide slit 112 is moved together with the linearly movable member 12 in the Z direction upward, and the cam roller 103 is swung around the rotation axis P of the blade member 4 by this movement. The rotation in the R direction toward the opening closed position of the member 4 is started in advance of the rotation of the blade member 5, and after the start, the linearly movable member 12 is further moved straight upward, as shown in FIG. As shown in FIG. 11, the blade member 4 and the driven blade members 6 and 7 rotated together with the blade member 4 are rotated in the R direction toward the opening closing position to gradually close the lower portion of the opening 3, and then FIG. Shown in Sea urchin, completely closes the lower opening 3 (partially closed). The cam roller 103 provided on the blade member 4 in the state shown in FIG. 12 via the support arm 102 has already been transferred from the guide slit 112 to the guide slit 111 via the curved path. The rotation ends, and the rotation of the driven blade members 6 and 7 also ends with the end of the rotation of the blade member 4.

一方、上方に向かって直動される直動自在部材12が図10に示すように位置する場合には、羽根部材5は、カムローラ123が案内スリット131に配されているためにそのR方向の回転が開始されず、当該直動自在部材12が更に上方に向かって直動されて図11に示すように位置する場合には、カムローラ123が案内スリット131から曲路を介して案内スリット132に移行するために、当該カムローラ123が旋回されて、羽根部材5の開口閉鎖位置に向かうR方向の回転が開始され、従動羽根部材8及び9もまた羽根部材5の回転と共に開口閉鎖位置に向かうR方向の回転が開始され、このように開始された羽根部材5並びに従動羽根部材8及び9の回転により、図11及び図12に示すように、開口3の上部を漸次閉鎖する。   On the other hand, when the linearly movable member 12 that is linearly moved upward is positioned as shown in FIG. 10, the blade member 5 is arranged in the R direction because the cam roller 123 is disposed in the guide slit 131. When the rotation is not started and the linearly movable member 12 is further moved upward and positioned as shown in FIG. 11, the cam roller 123 moves from the guide slit 131 to the guide slit 132 through the curved path. In order to make the transition, the cam roller 123 is turned to start rotation in the R direction toward the opening closed position of the blade member 5, and the driven blade members 8 and 9 also move toward the opening closed position along with the rotation of the blade member 5. The rotation of the direction is started, and the rotation of the blade member 5 and the driven blade members 8 and 9 thus started gradually closes the upper portion of the opening 3 as shown in FIGS.

以下、羽根部材4及び5並びに従動羽根羽根部材6、7、8及び9が開口完全開放位置に配されているルーバ装置1を動作させて開口3の完全閉鎖を行う場合について説明する。上述のようにルーバ装置1を動作させて開口3の下部の閉鎖を行った後、図12に示すように位置している直動自在部材12を更に上方に向かってZ方向に直動させることで羽根部材5並びに従動羽根部材8及び9を更に開口閉鎖位置に向かってR方向に回転させ、当該回転により開口3の上部を更に漸次閉鎖し、その後、図13に示すように、開口3の上部を完全に閉鎖する。このようにして、開口3の全体を完全に閉鎖する完全閉鎖を行う。   Hereinafter, the case where the louver device 1 in which the blade members 4 and 5 and the driven blade blade members 6, 7, 8, and 9 are arranged at the opening fully opened position is operated to completely close the opening 3 will be described. After the louver device 1 is operated to close the lower portion of the opening 3 as described above, the linearly movable member 12 positioned as shown in FIG. 12 is further moved in the Z direction further upward. Then, the blade member 5 and the driven blade members 8 and 9 are further rotated in the R direction toward the opening closing position, and the upper portion of the opening 3 is further gradually closed by the rotation, and thereafter, as shown in FIG. Close the top completely. In this way, a complete closure for completely closing the entire opening 3 is performed.

以下、羽根部材4及び5並びに従動羽根部材6、7、8及び9が図13に示すように開口完全閉鎖位置に配されているルーバ装置1を動作させて開口3の上部の開放(部分開放)を行う場合について説明する。まず、図9に示すように、被係止部材76を操作により係止部材75から離反させることで禁止手段13による直動自在部材12のZ方向の直動の禁止を解除する。   Hereinafter, the louver device 1 in which the blade members 4 and 5 and the driven blade members 6, 7, 8 and 9 are arranged in the fully closed position of the opening as shown in FIG. ) Will be described. First, as shown in FIG. 9, by prohibiting the locked member 76 from the locking member 75 by operation, the prohibition of the linear movement of the linearly movable member 12 by the prohibiting means 13 in the Z direction is canceled.

次に、被係止部材76を操作により下方に向かってZ方向に移動させ、この移動と共に直動自在部材12を図13に示す位置から下方に向かってZ方向に直動させ、この直動により案内スリット132に配されているカムローラ123を直動自在部材12と共に下方に向かってZ方向に移動させ、この移動によりカムローラ123を羽根部材5の回転軸心Pの回りで旋回させて、羽根部材5の開口開放位置に向かうR方向の回転を羽根部材4の回転に対して先行して開始し、開始後、直動自在部材12を更に下方に向かって直動させることで、図12及び図11に示すように、羽根部材5並びに羽根部材5と共に回転される従動羽根部材8及び9を開口開放位置に向かってR方向に回転させて開口3の上部を漸次開放し、その後、図10に示すように、開口3の上部を完全に開放(部分開放)する。図10に示す状態の羽根部材5に支持アーム122を介して設けられているカムローラ123は、案内スリット132から曲路を介して案内スリット131に既に移行されており、従って、羽根部材5の前記回転は終了し、従動羽根部材8及び9の前記回転もまた羽根部材5の回転の終了と共に終了する。   Next, the locked member 76 is moved downward in the Z direction by operation, and along with this movement, the linearly movable member 12 is linearly moved downward in the Z direction from the position shown in FIG. Accordingly, the cam roller 123 disposed in the guide slit 132 is moved downward in the Z direction together with the linearly movable member 12, and the cam roller 123 is swung around the rotation axis P of the blade member 5 by this movement. The rotation in the R direction toward the opening opening position of the member 5 is started in advance of the rotation of the blade member 4, and after the start, the linearly movable member 12 is further moved downward in FIG. As shown in FIG. 11, the blade member 5 and the driven blade members 8 and 9 rotated together with the blade member 5 are rotated in the R direction toward the opening opening position to gradually open the upper portion of the opening 3. Shown in As fully opened (partially open) the upper opening 3. The cam roller 123 provided on the blade member 5 in the state shown in FIG. 10 via the support arm 122 has already been transferred from the guide slit 132 to the guide slit 131 via the curved path. The rotation ends, and the rotation of the driven blade members 8 and 9 also ends when the rotation of the blade member 5 ends.

一方、下方に向かって直動される直動自在部材12が図12に示すように位置する場合には、羽根部材4は、カムローラ103が案内スリット111に配されているためにそのR方向の回転が開始されず、当該直動自在部材12が更に下方に向かって直動された場合には、カムローラ103が案内スリット111から曲路を介して案内スリット112に移行するために、当該カムローラ103が旋回されて、羽根部材4の開口開放位置に向かうR方向の回転が開始され、従動羽根部材6及び7もまた羽根部材4の回転と共に開口開放位置に向かうR方向の回転が開始され、このように開始された羽根部材4並びに従動羽根部材6及び7の回転により、図11及び図10に示すように、開口3の下部を漸次開放する。   On the other hand, when the linearly movable member 12 that is linearly moved downward is positioned as shown in FIG. 12, the blade member 4 is arranged in the R direction because the cam roller 103 is disposed in the guide slit 111. When the rotation is not started and the linearly movable member 12 is further moved downward, the cam roller 103 moves from the guide slit 111 to the guide slit 112 through the curved path. Is rotated to start rotation in the R direction toward the opening opening position of the blade member 4, and the driven blade members 6 and 7 also start to rotate in the R direction toward the opening opening position along with the rotation of the blade member 4. The rotation of the blade member 4 and the driven blade members 6 and 7 thus started gradually opens the lower portion of the opening 3 as shown in FIGS.

以下、羽根部材4及び5並びに従動羽根羽根部材6、7、8及び9が開口完全閉鎖位置に配されているルーバ装置1を動作させて開口3の完全開放を行う場合について説明する。上述のようにルーバ装置1を動作させて開口3の上部の開放を行った後、図10に示すように位置している直動自在部材12を更に下方に向かってZ方向に直動させることで羽根部材4並びに従動羽根部材6及び7を更に開口開放位置に向かってR方向に回転させ、当該回転により開口3の下部を更に漸次開放し、その後、図2に示すように、開口3の下部を完全に開放する。このようにして、開口3の全体を完全に開放する完全開放を行う。   Hereinafter, the case where the louver device 1 in which the blade members 4 and 5 and the driven blade blade members 6, 7, 8, and 9 are arranged at the opening fully closed position is operated to completely open the opening 3 will be described. After operating the louver device 1 to open the upper part of the opening 3 as described above, the linearly movable member 12 positioned as shown in FIG. 10 is further moved downward in the Z direction. Then, the blade member 4 and the driven blade members 6 and 7 are further rotated in the R direction toward the opening opening position, and the lower portion of the opening 3 is gradually opened by the rotation, and thereafter, as shown in FIG. Open the bottom completely. In this way, complete opening is performed to completely open the entire opening 3.

尚、被係止部材76の操作を解除して当該被係止部材76を係止部材75に係止させて直動自在部材12の直動を禁止することで、羽根部材4及び5並びに従動羽根部材6、7、8及び9による開口3の所望の閉鎖状態及び開放状態を保持することができる。   The operation of the locked member 76 is released and the locked member 76 is locked to the locking member 75 to prohibit the direct movement of the linearly movable member 12, thereby allowing the blade members 4 and 5 and the driven member to move. The desired closed state and open state of the opening 3 by the blade members 6, 7, 8 and 9 can be maintained.

以上のルーバ装置1によれば、互いに隣接して配されていると共に回転により開口3を開閉する少なくとも二つの羽根部材4及び5と、羽根部材4及び5に対してZ方向に直動自在である直動自在部材12と、羽根部材4を回転させるように直動自在部材12の直動を羽根部材4に伝達する伝達手段14と、羽根部材4とは異なる回転位相において羽根部材5を回転させるように直動自在部材12の直動を羽根部材5に伝達する伝達手段15とを具備しているために、直動自在部材12の直動により開口3の完全開放及び完全閉鎖並びに部分開放及び部分閉鎖を行うことができ、而して、簡単な操作で開口3を自在に開閉することができる。また、ルーバ装置1によれば、一つの直動自在部材12の直動に基づいて羽根部材4及び5を回転させることができ、羽根部材4及び5の夫々に対応して直動自在部材を複数設ける必要をなくすことができて、構成の簡略化を図ることができる。   According to the louver device 1 described above, at least two blade members 4 and 5 that are arranged adjacent to each other and open and close the opening 3 by rotation, and are directly movable in the Z direction with respect to the blade members 4 and 5. A certain linearly movable member 12, a transmission means 14 for transmitting the linear motion of the linearly movable member 12 to the blade member 4 so as to rotate the blade member 4, and the blade member 5 is rotated at a rotational phase different from that of the blade member 4. Since the transmission means 15 for transmitting the linear motion of the linearly movable member 12 to the blade member 5 is provided, the opening 3 is fully opened and completely closed and partially opened by the linear motion of the linearly movable member 12. In addition, the opening 3 can be freely opened and closed by a simple operation. Further, according to the louver device 1, the blade members 4 and 5 can be rotated based on the linear movement of one linearly movable member 12, and the linearly movable members are respectively corresponding to the blade members 4 and 5. It is possible to eliminate the need to provide a plurality of components and to simplify the configuration.

ルーバ装置1によれば、カムローラ案内部101は、カムローラ103をZ方向に案内する案内スリット111と、案内スリット111に連続していると共にカムローラ103をY方向に案内する案内スリット112とを具備しており、カムローラ案内部121は、カムローラ123をZ方向に案内する案内スリット131と、案内スリット131に連続していると共にカムローラ123をY方向に案内する案内スリット132とを具備しており、カムローラ103は、図2及び図10に示すように、カムローラ123が案内スリット131に配される場合には、案内スリット112に配される一方、図12及び図13に示すように、カムローラ123が案内スリット132に配される場合には、案内スリット131に配されるようになっているために、直動自在部材12の直動において、案内スリット111に配されるカムローラ103を羽根部材4の回転軸心Pの回りで旋回させない一方、案内スリット112に配されるカムローラ103を羽根部材4の回転軸心Pの回りで旋回させることができ、案内スリット131に配されるカムローラ123を羽根部材5の回転軸心Pの回りで旋回させない一方、案内スリット132に配されるカムローラ123を羽根部材5の回転軸心Pの回りで旋回させることができ、而して、簡単な操作で開口3を自在に開閉することができ、また、直動自在部材12の直動により羽根部材4の回転を羽根部材5の回転よりも先に又は羽根部材5の回転を羽根部材4の回転よりも先に開始若しくは終了させることができる。   According to the louver device 1, the cam roller guide portion 101 includes a guide slit 111 that guides the cam roller 103 in the Z direction, and a guide slit 112 that continues to the guide slit 111 and guides the cam roller 103 in the Y direction. The cam roller guide portion 121 includes a guide slit 131 that guides the cam roller 123 in the Z direction, and a guide slit 132 that continues to the guide slit 131 and guides the cam roller 123 in the Y direction. 2 and 10, when the cam roller 123 is arranged in the guide slit 131, the cam roller 123 is arranged in the guide slit 112, while the cam roller 123 is guided as shown in FIGS. When arranged in the slit 132, it is arranged in the guide slit 131. Therefore, in the linear motion of the linearly movable member 12, the cam roller 103 disposed in the guide slit 111 is not swung around the rotation axis P of the blade member 4, while the cam roller 103 disposed in the guide slit 112 is not rotated. The cam roller 123 disposed in the guide slit 131 can be swung around the rotation axis P of the member 4 and the cam roller 123 disposed in the guide slit 132 is not swung around the rotation axis P of the blade member 5. Can be swung around the rotation axis P of the blade member 5, and thus the opening 3 can be freely opened and closed by a simple operation. The rotation of 4 can be started or ended before the rotation of the blade member 5 or the rotation of the blade member 5 can be started or ended before the rotation of the blade member 4.

ルーバ装置1によれば、直動自在部材12の直動を解除自在に禁止する禁止手段13を具備しているために、開口3の開放及び閉鎖状態を確実に保持することができる。   According to the louver device 1, since the prohibiting means 13 for prohibiting the direct movement of the linearly movable member 12 is releasably provided, the open and closed states of the opening 3 can be reliably held.
