JP 2013-23840 A

  However, in the above prior art, in order to return the slat held in the open posture to the closed posture, it is necessary to raise the slat to above the partition wall. For this reason, when the slat located on the lower end side of the shutter curtain is in the open posture, there is a problem that it takes a long time to return the slat to the closed posture. In addition, there was room for improvement.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a shutter device that can quickly return a slat in an open position to a closed position.

  A shutter device that solves the above-mentioned problems includes a shutter curtain formed by connecting a plurality of slats having a support shaft serving as a rotation center at a longitudinal end portion thereof, and a winder. An elevating device for elevating and lowering, a guide rail having a guide passage engaged with the support shaft and guiding each slat, a first passage in which the support shaft engages the guide passage, and the first passage A partition wall partitioned into a second passage parallel to the guide passage, a posture control device capable of rotating each slat descending along the guide passage above the partition wall, and a longitudinal end of the slat The slat is held in a closed position by being engaged with the first passage and is engaged with the second passage as the slat is rotated above the partition wall. An engaging projection that holds the slat in an open posture, and a biasing member that urges the slat to rotate in the closed posture return direction. The partition wall includes the engaging projection that is in the second passage. A rotation of the slats in the return direction of the closed posture by being in contact with the side wall surface on the side, and the first and second passages communicate with the partition wall. A connecting hole is provided, and when the slats are lowered, the connecting hole is configured to move the engaging protrusion engaging the second passage toward the first passage through the connecting hole. There is provided a guide member that regulates and allows the engaging protrusion engaging with the second passage to move toward the first passage through the communication hole when the slats are raised. It is preferable.

  According to the said structure, the engagement protrusion which engages with a 2nd channel | path can be moved to the 1st channel | path side via the connecting hole formed in the partition wall at the time of the raising operation | movement of a shutter curtain. That is, as the shutter curtain ascends, the engaging projection that engages with the second passage reaches the formation portion of the communication hole, thereby allowing the slat biased by the biasing member to rotate. As a result, the slats held in the open posture can be returned to the closed posture with a smaller ascending operation of the shutter curtain without moving to the upper end of the partition wall.

  Further, during the lowering operation of the shutter curtain, it is possible to prevent the engagement protrusion engaging with the second passage from moving toward the first passage. And thereby, the open attitude | position of the slat can be hold | maintained also under the site | part in which the communicating hole was formed.

  In the shutter device that solves the above problem, the guide member extends downward from the upper end portion of the communication hole to form a guide surface of the engaging protrusion that descends the second passage. It is preferable that the distal end side includes a guide wall disposed so as to protrude into the second passage.

  According to the above configuration, when the shutter curtain is lifted, movement of the engaging protrusion engaging with the second passage toward the first passage through the communication hole is allowed. Further, when the shutter curtain is lowered, the engaging protrusion engaging with the second passage slides on the guide surface formed by the guide wall so that the connecting hole is formed from the top to the bottom. Moving. Further, the engaging protrusion is separated from the guide surface formed by the guide wall on the tip side protruding into the second passage. And thereby, before the engagement protrusion part engaged with a 2nd channel | path moves to the 1st channel | path side via a communication hole, the formation site | part of the said communication hole can be passed.

  Therefore, according to the above configuration, it is possible to prevent the engagement protrusion engaging with the second passage from moving toward the first passage when the shutter curtain is lowered. And thereby, the open attitude | position of the slat can be hold | maintained also under the site | part in which the communicating hole was formed.

In the shutter device that solves the above-described problems, it is preferable that the guide wall is elastically deformable at the distal end side in the thickness direction of the partition wall.
According to the said structure, an engaging protrusion can be spaced apart from the guide surface which the guide wall forms more smoothly. In addition, when the shutter curtain is lifted, even when the engaging protrusion that has reached the site where the communication hole is formed contacts the guide wall, the impact caused by the contact can be reduced. And thereby, the smooth raising / lowering operation | movement of the shutter curtain can be ensured.

  In the shutter device that solves the above-described problem, an inclined surface that extends from the second passage side to the first passage side is formed at the lower end portion of the communication hole continuously from the side wall surface of the partition wall on the second passage side. It is preferred that

  According to the above configuration, even when the engaging protrusion separated from the guide surface formed by the guide wall enters the communication hole from the second passage side, it is formed at the lower end of the communication hole. By coming into contact with the slope, it moves below the lower end in a manner of sliding on the slope. As a result, it is possible to more reliably prevent the engaging protrusion engaging with the second passage from moving toward the first passage when the shutter curtain is lowered.

  In addition, when the shutter curtain is raised, the engaging protrusion that engages with the second passage enters the communication hole while being guided by the slope. And thereby, the engaging protrusion can be moved more smoothly from the second passage side to the first passage side.

  In the shutter device that solves the above-described problem, the guide member extends upward from a lower end portion of the communication hole to close the communication hole, and the engagement is based on the urging force of the urging member. It is preferable to provide a guide wall whose tip side tilts toward the first passage when pressed by the protrusion.

  According to the above configuration, when the shutter curtain is lifted, the engagement protrusion that engages with the second passage through the gap formed by the upper end of the guide wall tilting toward the first passage is the first. It will be able to move to the passage side. Further, when the shutter curtain is lowered, the engaging protrusion engaging with the second passage slides on the guide surface formed by the guide wall so that the connecting hole is formed from the top to the bottom. Moving. And thereby, the 2nd engaging part can be made to pass through the formation part of the connection hole, without moving to the 1st channel | path side through the clearance gap formed by the inclination of the guide wall.

  Therefore, according to the above configuration, it is possible to prevent the engagement protrusion engaging with the second passage from moving toward the first passage when the shutter curtain is lowered. And thereby, the open attitude | position of the slat can be hold | maintained also under the site | part in which the communicating hole was formed.

  A shutter device that solves the above-described problem includes a selective opening control device that selectively shifts each slat constituting the shutter curtain to the opening posture, and the selective opening control device detects a lifting operation position of each slat. A position detection unit that performs the operation, a storage unit that holds a plurality of open patterns indicating combinations of the open slats to be held in the open posture and the closed slats to be held in the closed posture, and any one of the open patterns is selected. An open selection unit; a determination unit that determines whether or not the open slat in the selected open pattern is descending a posture control section set above the partition wall; and the open slat is the posture control section It is preferable to include a selection operation control unit that operates the posture control device when moving down.

  According to the said structure, each slat can be selectively hold | maintained in an open posture by arbitrary combinations. And the opening part of the shutter curtain can be formed in the optimal position according to a use condition by switching the open pattern.

  According to the present invention, the slat in the open posture can be returned to the closed posture more quickly.

  Specifically, as shown in FIGS. 2 and 3, in the shutter device 1 of the present embodiment, each slat 2 has a longitudinal direction of a slat body 10 formed using a light metal material such as an aluminum alloy, for example. It is formed by fitting the slat cap 11 formed using resin to the end. The slat cap 11 is provided with a support shaft 12 that extends outward in the longitudinal direction when fitted to the slat body 10. As shown in FIGS. 2, 3 and 4A and 4B, the shutter device 1 of the present embodiment includes a metal shaft-like member 13 penetrating the support shaft 12 in the axial direction, A link plate 16 fixed to one end of a shaft-like member 13 projecting from the tip of the support shaft 12.

  As shown in FIGS. 4A and 5A and 5B, in the shutter device 1 of the present embodiment, each link plate 16 has a long, substantially flat outer shape. As a result, the end portions in the longitudinal direction are arranged adjacent to the adjacent link plates 16 between the slats 2 that are arranged to form the shutter curtain 3. .

  Each of the link plates 16 has long holes 16 a and 16 b extending in the longitudinal direction of the link plate 16 at two positions sandwiching the fixing portion with respect to the shaft-shaped member 13. The shutter device 1 of the present embodiment includes a plurality of connection link plates 17 having a pair of connection pins 17a and 17b inserted into the long holes 16a and 16b.

  In other words, in the present embodiment, the chain 18 is formed by connecting the link plates 16 via the connecting link plates 17. Further, the chain 18 can be expanded and contracted by moving the connecting pins 17a and 17b of the connecting link plate 17 inserted into the long holes 16a and 16b of the link plates 16 through the long holes 16a and 16b, respectively. It is configured. Further, the chain 18 allows relative rotation between the link plates 16 and the connection link plates 17 using the connection pins 17a and 17b as rotation axes. Thus, the shutter device 1 of the present embodiment is configured such that the slats 2 aligned to form the shutter curtain 3 are connected via the chain 18 so as to be able to be wound.

  As shown in FIG. 1, the lifting device 5 of this embodiment includes a winder 22 that uses a motor 20 as a drive source. And it is the structure which raises / lowers the said shutter curtain 3 by winding and unwinding the shutter curtain 3 using this winder 22. As shown in FIG.

  Furthermore, as shown in FIGS. 6A and 6B, in the present embodiment, the upper end (the upper end in FIG. 6) of the slat body 10 is in the longitudinal direction (in the same figure, orthogonal to the paper surface). A ridge 25 extending in the direction) is formed. A groove-like fitting recess 26 extending in the longitudinal direction is formed at the lower end of the slat body 10 (the lower end in the figure).

  That is, in the shutter device 1 of the present embodiment, the chain 18 connecting the slats 2 is contracted by the lowering operation of the shutter curtain 3 (see FIG. 5A). The shutter curtain 3 according to the present embodiment is configured such that the spacing between the slats 2 is thereby narrowed so that the protrusions 25 and the fitting recesses 26 of the slats 2 (slat main bodies 10) adjacent in the vertical direction are fitted. Configured to match.

  As shown in FIGS. 2 and 3, in the shutter device 1 of the present embodiment, the slat cap 11 constituting the end portion in the width direction of each slat 2 is around the shaft-like member 13 that penetrates the support shaft 12. It has a configuration that allows relative rotation. Note that the fitting between the protrusion 25 and the fitting recess 26 is eliminated by the chain 18 extending with the ascending operation of the shutter curtain 3 (see FIG. 5B) and the interval between the slats 2 being widened. Is done. Then, as shown in FIG. 6B, the shutter device 1 of the present embodiment shifts each slat 2 from the closed posture to the open posture by rotating each slat 2 around the support shaft 12. It is possible to make it.

  More specifically, as shown in FIGS. 7A and 7B, the shutter device 1 of the present embodiment extends the guide passage 24 of the guide rail 4 in parallel with the extending direction (vertical direction in FIG. 7). A partition wall 33 that partitions the first passage 31 and the second passage 32 is provided. Each slat 2 is configured to move in the ascending / descending operation direction of the shutter curtain 3, that is, in the vertical direction in FIG. 7, with the support shaft 12 engaged with the first passage 31.

  Further, the shutter device 1 includes an attitude control device 35 that can rotate each slat 2 descending along the guide passage 24 above the partition wall 33. Further, as shown in FIG. 2 and FIG. 3, the slat cap 11 constituting the longitudinal end of each slat 2 has an engaging projection that protrudes outward in the longitudinal direction of each slat 2, similar to its support shaft 12. A portion 36 is provided. Then, as shown in FIGS. 7A and 7B, in the shutter device 1 of the present embodiment, the engagement protrusion 36 is engaged with either the first passage 31 or the second passage 32 of the guide rail 4. By doing so, each slat 2 can be held in either a closed posture or an open posture.

  Specifically, in the shutter device 1 of the present embodiment, the posture of each slat 2 that is fed out as the shutter curtain 3 from the winder 22 of the lifting device 5 is short of each slat 2 having a long and substantially flat plate shape. The slat cap 11 constituting the side portion, that is, the end portion in the longitudinal direction, is in a closed posture along the extending direction of the guide rail 4.

  As shown in FIG. 2, in this embodiment, the slat cap 11 provided with the support shaft 12 and the link plate 16 provided at the tip of the shaft-like member 13 penetrating the support shaft 12 are respectively Based on the elastic force of the torsion coil spring 34 inserted into the shaft-like member 13, it is urged to rotate in directions opposite to each other. Further, the support shaft 12 and the link plate 16 of the slat cap 11 are provided with stopper portions 12c and 16c that restrict relative rotation of the slat cap 11 and the link plate 16 by abutting each other. And each slat 2 of this embodiment maintains the closed posture by this.

  That is, as shown in FIG. 7A, when the posture control by the posture control device 35 is not performed, each slat 2 is engaged with the slat cap 11 while maintaining the closed posture. The protruding portion 36 is engaged with the first passage 31 like the support shaft 12. The shutter device 1 of the present embodiment thereby moves the engagement protrusion 36 from the first passage 31 side toward the second passage 32 side separated by the partition wall 33, that is, from the closed posture to the open posture. By restricting the rotation of the slat 2 in the direction of shifting to (in the clockwise direction in FIG. 7), the slat 2 is held in a closed posture.

  On the other hand, as shown in FIG. 7B, each slat 2 rotates around the support shaft 12 provided in the slat cap 11 by receiving the posture control by the posture control device 35. Then, each slat 2 shifts to an open posture in which the slat cap 11 constituting the short side portion of each slat 2 having a long and substantially flat plate shape intersects the extending direction of the guide rail 4.

  In addition, each slat 2 is configured such that an engaging projection 36 provided on the slat cap 11 is engaged with the second passage 32 by rotating above the partition wall 33. The shutter device 1 of the present embodiment thereby moves the engagement protrusion 36 from the second passage 32 side toward the first passage 31 side separated by the partition wall 33, that is, from the open posture to the closed posture. By restricting the rotation of the slat 2 in the direction of shifting to (in the counterclockwise direction in FIG. 7), the slat 2 is held in an open posture.

  More specifically, as shown in FIGS. 2 and 3, each slat 2 of the present embodiment has a pressure receiving protrusion 37 that protrudes radially outward from the peripheral surface of the support shaft 12. As shown in FIGS. 8 and 9, the attitude control device 35 of the present embodiment engages with the pressure receiving protrusion 37 when each slat 2 descends along the guide passage 24 of the guide rail 4. Thus, an operation member 38 capable of rotating each slat 2 is provided.

  Specifically, in the attitude control device 35 of the present embodiment, the operation member 38 extends along the direction in which the support shaft 12 extends from the longitudinal end portion of each slat 2 (the left-right direction in each figure). It has an elongated substantially rod shape that extends. Further, a link member 40 that connects the operation member 38 to the solenoid 39 is connected to the base end side (the left end portion in each figure) of the operation member 38. An operation portion 41 formed in a flange shape is provided at the distal end of the operation member 38 (the right end portion in each drawing).

  As shown in FIG. 8, in the posture control device 35 of the present embodiment, the operation unit 41 provided at the tip of the operation member 38 moves in the guide passage 24 as the shutter curtain 3 moves up and down when not operating. It is configured to be arranged on the base end side (right side in the figure) of the support shaft 12 with respect to the passing track T1 of the pressure receiving protrusion 37 provided on the support shaft 12.

  That is, when the attitude control device 35 is in the OFF state, the operation portion 41 provided at the tip of the operation member 38 is in a position where it does not contact the pressure receiving protrusion 37 provided on the support shaft 12 of each slat 2. It is arranged. Then, the posture control device 35 of the present embodiment thereby allows the posture control section set above the partition wall 33 while the slat 2 descending along the guide passage 24 of the guide rail 4 maintains the closed posture. It is configured to pass through X1.

  Further, as shown in FIG. 9, the solenoid 39 of the present embodiment has a configuration in which a plunger 39a protruding to the outside is drawn inward (moves upward in FIG. 9) when energized. Then, the attitude control device 35 of the present embodiment transmits the driving force of the solenoid 39 to the operation member 38 via the link member 40, thereby causing the operation portion 41 provided at the tip of the operation member 38 to receive a pressure. It is configured to move on the passage trajectory T1 of the portion 37.

  That is, when the attitude control device 35 is turned on, the slat 2 passing through the attitude control section X1 set above the partition wall 33 has the pressure receiving projection 37 provided on the support shaft 12 at the tip of the operation member 38. It is adapted to engage with the provided operation unit 41. Then, the posture control device 35 of the present embodiment is configured to shift the slat 2 from the closed posture to the open posture by rotating the slat 2 around the support shaft 12.

Are assembled (see FIGS. 2 and 3). Specifically, these two divided bodies 51 and 52 are configured to be assembled together along the axial direction of the support shaft 12. Each of the divided bodies 51 and 52 is formed with insertion holes 51a and 52a through which the shaft-like member 13 penetrating the support shaft 12 is inserted.

  Furthermore, the shutter device 1 of the present embodiment includes a rotation member 54 that is provided so as to be rotatable relative to the slat cap 11. Specifically, the rotating member 54 has an insertion hole 54 a at the base end portion and is pivotally supported by the shaft-like member 13, so that the rotation member 54 is interposed between the first and second divided bodies 51 and 52. It is configured to be sandwiched. The engaging protrusion 36 of the present embodiment is provided at the tip of the rotating member 54.

  That is, the rotating member 54 rotates relative to the slat cap body 55 formed by the first and second divided bodies 51 and 52 with the shaft-like member 13 inserted through the insertion hole 54a as a rotating shaft. It has a movable configuration. The shutter device 1 of the present embodiment is based on the relative displacement of the engaging protrusion 36 with respect to the longitudinal end of the slat 2 that is generated by the relative rotation of the rotating member 54 and the slat cap body 55. The slats 2 are allowed to rotate in the section where the partition wall 33 exists.

  More specifically, as shown in FIGS. 10 to 12, in this embodiment, a torsion coil spring 56 as an urging member is provided on the shaft-like member 13 constituting the turning shaft of the turning member 54 and the slat cap body 55. Is inserted. In the present embodiment, the torsion coil spring 56 is housed in the insertion hole 52a provided in the second divided body 52 in a mode that penetrates the support shaft 12 in the axial direction together with the shaft-like member 13. It has become. The slat cap 11 of the present embodiment is urged to rotate in the direction in which the rotating member 54 and the slat cap body 55 are opposite to each other based on the elastic force (elastic restoring force) of the torsion coil spring 56. It is configured.

  Specifically, the rotating member 54 of the present embodiment rotates in a direction that coincides with the direction in which each slat 2 transitions from the closed posture to the open posture (open posture transition direction), that is, in the counterclockwise direction in FIG. It is energized. Further, the slat cap body 55 is urged to rotate in a direction coinciding with the direction in which each slat 2 returns from the open posture to the closed posture (closed posture return direction), that is, in the clockwise direction in FIG. The slat cap 11 of the present embodiment is configured so that the rotating member 54 and the slat cap body 55 are pressed against each other based on the biasing force of the torsion coil spring 56, so that the rotating member 54 and the slat cap body 55. The relative rotation position between them is held.

  In the present embodiment, a stopper portion 54 c that protrudes in the extending direction of the rotating member 54 is formed at the tip of the rotating member 54. Further, the slat cap body 55 (first divided body 51) has a relative rotation between the rotation member 54 and the slat cap body 55 based on the biasing force of the torsion coil spring 56, so A stopper portion 55c that contacts the stopper portion 54c is formed. The slat cap 11 of the present embodiment includes a rotating member 54 and a slat cap main body 55 that are urged to rotate based on the urging force of the torsion coil spring 56 at a position where the stopper portions 54c and 55c abut each other. The relative rotation position between the two is held.

  In the shutter device 1 of the present embodiment, the pivot 12 and the rotation member 54 provided in the slat cap body 55 are maintained in such a state that the relative rotation positions of the rotation member 54 and the slat cap body 55 are held. The engaging projection 36 provided on the slat 2 is engaged with the first passage 31 so that the slat 2 is held in the closed posture (see FIG. 7A). Similarly, in a state where the relative rotation position of the rotation member 54 and the slat cap body 55 is maintained, the support shaft 12 provided on the slat cap body 55 engages with the first passage 31, and the rotation member 54. The engaging projection 36 provided on the slat 2 is configured to engage with the second passage 32 so that the slat 2 is held in an open posture (see FIG. 7B).

  Here, as shown in FIG. 11, when the engaging protrusion 36 is engaged with the second passage 32, the engaging protrusion 36 comes into contact with the partition wall 33, thereby causing the second passage 32 to contact. The rotation of the rotation member 54 from the side toward the first passage 31 (the rotation in the clockwise direction in the figure) is restricted. Further, the stopper portion 55c on the slat cap main body 55 side abuts on the stopper portion 54c of the rotating member 54, so that the rotation of the slat cap main body 55 from the second passage 32 side toward the first passage 31 side is similarly restricted. Is done. Thus, the shutter device 1 of the present embodiment is configured to restrict the rotation in the closing posture return direction when each slat 2 is in the section where the partition wall 33 exists.

  On the other hand, as shown in FIG. 12, even when the engaging protrusion 36 is engaged with the first passage 31, the engaging protrusion 36 provided on the rotating member 54 is not affected by the first passage 31. The rotating member 54 comes into contact with the partition wall 33 by the rotation of the rotating member 54 from the side toward the second passage 32 side (counterclockwise rotation in the figure). However, the stopper portion 55c provided on the slat cap main body 55 contacts the stopper portion 54c on the rotating member 54 side by the rotation of the slat cap main body 55 from the first passage 31 side toward the second passage 32 side. There is no contact.

  That is, even in this state, the slat cap body 55 can relatively rotate against the urging force of the torsion coil spring 56. Thus, the shutter device 1 of the present embodiment is configured to allow the rotation in the opening posture transition direction when the slat 2 is in the section where the partition wall 33 exists, that is, the transition from the closing posture to the opening posture. It has become.

  2, 3, and 10, the slat cap 11 of the present embodiment has an outer side in the longitudinal direction of each slat 2 (the right side in FIG. 2) as well as the support shaft 12 and the engaging projection 36. A locking pin 58 is provided as a locking protrusion protruding in the direction from the left to the left).

  In the present embodiment, the locking pin 58 is provided at a position opposite to the stopper portion 55c with the support shaft 12 in between. In the present embodiment, the locking pin 58 is formed integrally with the second divided body 52.

The locking member 63 has a fitting portion 63c having a substantially arc-shaped cross section at a second side end 63b opposite to the first side end 63a provided with each locking groove 62. . The engaging member 63 is pivotally supported in the guide passage 24 in a rotatable state when the fitting portion 63c is fitted to the turning shaft 65 formed on the guide rail 4. ing.

  That is, when the second attitude control device 60 is not operated, the locking member 63 of the present embodiment is guided by the locking grooves 62 provided in the first side end 63a as the shutter curtain 3 moves up and down. The rotational position of the locking pin 58 that moves in the passage 24 is maintained so as to be spaced apart from the passing track T2. Further, the locking member 63 is rotated clockwise in FIG. 14 by being driven by the drive mechanism 64. Thus, each of the locking grooves 62 is arranged on the passing track T2 of the locking pin 58, so that the locking pin 58 of each slat 2 can be locked. Yes.

And the drive mechanism 64 of this embodiment is comprised so that the capture member 67 and the cam member 68 may rotate in response to the engagement relationship of these cam grooves 72 and the engagement pins 73. .

  Specifically, the capture member 67 of the present embodiment is rotated based on the driving force of the solenoid 66, so that the opening end of the engagement groove 70 moves in the guide passage 24 as the shutter curtain 3 moves up and down. It is comprised so that it may be arrange | positioned on the passage track | orbit T3 of the spindle 12 to do. In this embodiment, the support shaft of each slat 2 is engaged with the engagement groove 70 of the capture member 67 (see FIG. 13B).

  Furthermore, the capture member 67 of this embodiment is pushed up to the support shaft 12 of the slat 2 engaged with the engagement groove 70 when the shutter curtain 3 rises in this state. It rotates in the turning direction. Further, the cam member 68 of the present embodiment is interlocked with the rotation of the capturing member 67, that is, based on the pressing force of the slat 2 rising in the guide passage 24 based on the driving force of the lifting device 5 in FIG.

It is comprised so that it may be arrange | positioned on 58 passage orbit T2 (refer FIG.13 (c)).

  That is, the locking member 63 of the present embodiment is configured such that the locking pin 58 of each slat 2 can be locked in each locking groove 62 when the shutter curtain 3 rises in this state. . The second attitude control device 60 of the present embodiment further opens the slats 2 with the locking pin 58 locked to the locking member 63 as a fulcrum when the shutter curtain 3 is further raised in this state. It can be rotated in the posture transition direction (see FIG. 13D).

  Further, the rotation angle of each slat 2 caused by this depends on the amount of lifting operation of the shutter curtain 3 after the locking member 63 locks the locking pin 58. And the 2nd attitude | position control apparatus 60 of this embodiment becomes a structure which can adjust freely the opening degree of each slat 2 which changed to the open attitude | position from the closed attitude | position by this.

  Specifically, the second posture control device 60 of the present embodiment is configured so that the slats 2 that have shifted to the open posture are fully opened by continuing the ascending operation of the shutter curtain 3 after the ON operation. It is configured. The opening degree of each slat 2 can be adjusted by stopping the ascending operation of the shutter curtain 3 before the fully open state or by moving the shutter curtain 3 downward.

  In the shutter device 1 of the present embodiment, the lifting operation of the shutter curtain 3 by the lifting device 5 is automatically stopped at the position where each slat 2 locked by the locking member 63 is fully opened. It is configured. In the shutter device 1 according to the present embodiment, the locking pin 58 is locked by the locking member 63 in the lifting / lowering position where each slat 2 returns from the open position to the closed position as the shutter curtain 3 moves down. It is configured to be released.

  As shown in FIGS. 14 and 15 (a), the partition wall 33 of the present embodiment has a communication hole that communicates between the first passage 31 and the second passage 32 partitioned by the partition wall 33. 75 is provided. Further, the communication hole 75 extends downward from the upper end portion 75a of the communication hole 75 (lower side in FIG. 15A) to lower the inside of the second passage 32. A guide member 81 having a guide wall 80 that forms a guide surface 80 s of the portion 36 is provided. And this guide member 81 is comprised so that the front-end | tip 80a side of the guide wall 80 may be protruded and arrange | positioned in the 2nd channel | path 32 by arrange | positioning in the communication hole 75 (FIG. 15 (a)). Projected to the left and inside).

  That is, in the shutter device 1 of the present embodiment, each slat 2 is urged to rotate in the closing posture return direction based on the urging force of the torsion coil spring 34 inserted and inserted into the shaft-like member 13 serving as the rotation axis. (See FIG. 7, counterclockwise direction in FIG. 7). In addition, the communication hole 75 formed in the partition wall 33 rotates the slats 2 in the closed posture return direction by moving the engagement protrusion 36 from the second passage 32 side to the first passage 31 side. It is tolerated. The shutter device 1 according to the present embodiment can thereby return the slat 2 held in the open posture to the closed posture with a smaller ascending operation of the shutter curtain 3 without moving the slat 2 to the upper end of the partition wall 33. Is possible.

  However, when the communication hole 75 is simply formed, even when the shutter curtain 3 is lowered, the engagement protrusion 36 that engages with the second passage 32 reaches the site where the communication hole 75 is formed. The slat 2 held in the posture returns to the closed posture.

  In view of this point, in the present embodiment, the guide member 81 is provided in a communication hole 75 formed in the middle of the partition wall 33. And the shutter apparatus 1 of this embodiment prevents the movement to the 1st channel | path 31 side of the engaging protrusion 36 engaged with the 2nd channel | path 32 by this at the time of the downward movement of the shutter curtain 3, Even under the portion where the communication hole 75 is formed, the open posture of each slat 2 can be maintained.

  More specifically, as shown in FIGS. 15A and 15B, the guide member 81 of the present embodiment is substantially the same as the fixing portion 81 a having a substantially flat outer shape fixed to the guide rail 4. A support portion 81b having a flat outer shape and substantially orthogonal to the fixed portion 81a. And the guide wall 80 is supported by the said support part 81b in the aspect substantially parallel to the support part 81b.

  Further, in the shutter device 1 of the present embodiment, the guide member 81 is disposed in the communication hole 75 in such a manner that the fixing portion 81 a is substantially orthogonal to the partition wall 33. The guide surface 80 s formed by the guide wall 80 is fixed in the communication hole 75 in such a manner as to be continuous with the side wall surface 33 b on the second passage 32 side in the partition wall 33.

  Furthermore, in the present embodiment, the lower end 75b of the communication hole 75 is connected to the side wall surface 33b on the second passage 32 side of the partition wall 33 from the second passage 32 side to the first passage 31 side (FIG. 15 ( A slope 83 extending from the left side to the right side in a) is formed. Further, the guide member 81 of the present embodiment has a guide wall 80, a fixed portion 81a, and a support portion 81b that are integrally formed using resin. And the guide member 81 of this embodiment is the structure by which the front-end | tip 80a side of the guide wall 80 is elastically deformable in the thickness direction (FIG. 15 (a) left-right direction) of the partition wall 33 by this. .

  That is, as shown in FIGS. 16A to 16C, when the shutter curtain 3 is lowered, the engaging protrusion 36 that engages with the second passage 32 moves on the guide surface 80 s formed by the guide wall 80. The part where the communication hole 75 is formed moves from the upper side to the lower side while sliding. Then, when the engaging projection 36 is separated from the tip 80a of the guide wall 80, the slat 2 held in the open posture is rotated in the closed posture return direction based on the biasing force of the torsion coil spring 34. .

  However, the guide wall 80 of the present embodiment is arranged such that the tip 80 a side extending downward from the upper end portion 75 a of the communication hole 75 protrudes into the second passage 32. For this reason, the engaging protrusion 36 separated from the distal end 80a of the guide wall 80 is moved by the lowering of the slat 2 before moving from the second passage 32 side to the first passage 31 side via the communication hole 75. It reaches the lower side of the lower end 75b of 75. Thus, the shutter device 1 of the present embodiment is configured so that the open posture of each slat 2 is maintained even below the portion where the communication hole 75 is formed.

  In the shutter device 1 of the present embodiment, the engaging protrusion 36 that is separated from the front end 80 a of the guide wall 80 abuts on the inclined surface 83 formed at the lower end 75 b of the communication hole 75. Then, the engaging protrusion 36 that is in contact with the inclined surface 83 is configured to move below the lower end portion 75 b of the communication hole 75 in such a manner that it slides on the inclined surface 83.

  On the other hand, as shown in FIGS. 16D to 16F, when the slat 2 held in the open posture is below the communication hole 75, the shutter curtain 3 moves upward to the second passage. The rotating engagement protrusion 36 is disposed at a position that can move to the first passage 31 side through the communication hole 75. At this time, the guide member 81 of the present embodiment is configured such that the guide wall 80 does not interfere with the engaging protrusion 36 that moves from the second passage 32 side to the first passage 31 side. Thus, the shutter device 1 of the present embodiment allows the slat 2 to rotate based on the biasing force of the torsion coil spring 34, thereby quickly returning the slat 2 held in the open posture to the closed posture. It is possible to make it.

Next, an electrical configuration of the shutter device 1 in the present embodiment and a control mode thereof will be described.
As shown in FIG. 17, the shutter device 1 of this embodiment includes an ECU 85 that supplies driving power to the motor 20 that is a driving source of the lifting device 5. In the present embodiment, the ECU 85 uses the solenoid 39 of the first attitude control device 35 that rotates each slat 2 above the partition wall 33 and the locking pin 58 provided on each slat 2 as fulcrums. The drive power is also supplied to the solenoid 66 of the second attitude control device 60 that rotates each slat 2. And ECU85 of this embodiment controls the action | operation of these raising / lowering apparatuses 5, the 1st attitude | position control apparatus 35, and the 2nd attitude | position control apparatus 60 through the supply of the drive electric power.

  Specifically, the lifting device 5 of this embodiment is provided with a pulse sensor 86 that outputs a pulse signal Sp synchronized with the operation of the winder 22. Then, the ECU 85 of the present embodiment counts the pulse output indicated by the pulse signal Sp, thereby raising and lowering the shutter curtain 3 and, more specifically, each slat 2 (2a to 2l) constituting the shutter curtain 3. Detects the lifting / lowering operation position.

  In addition, an operation input signal Sc indicating generation of an operation input to the input device 87 such as a switch or a remote controller is input to the ECU 85. Further, the ECU 85 provides information (external environment information Ie) regarding the environment outside the house partitioned by the shutter curtain 3, that is, the external environment where the shutter device 1 is placed, such as outside air temperature, wind speed, or noise. get. Then, the ECU 85 of the present embodiment lifts and lowers based on the detected operation input to the input device 87, the lifting / lowering position of each slat 2 (2a to 2l), and the external environment where the shutter device 1 is placed. The operation of the device 5, the first posture control device 35, and the second posture control device 60 is controlled.

  More specifically, in the shutter device 1 of the present embodiment, the ECU 85 controls each slat by the normal control for moving the shutter curtain 3 up and down based on the operation input to the input device 87 and the operation of the second attitude control device 60. 2 is executed (see FIG. 13).

  Further, as shown in FIGS. 17 and 18, the ECU 85 of the present embodiment has a slat 2 (open slat) to be held in an open posture and a closed posture in the storage area 88 by the operation of the first posture control device 35. A plurality of open patterns P indicating combinations of slats 2 (closed slats) to be held are held.

  In the present embodiment, the storage area 88 of the ECU 85 includes a first opening pattern P1 indicating that the upper three slats 2 (2j to 2l) in the shutter curtain 3 should be open slats, and a lower side. A second opening pattern P2 indicating that the three slats 2 (2a to 2c) should be opened slats is stored. The storage area 88 stores a third release pattern P3 indicating that the three upper and lower slats 2 (2a to 2c, 2j to 2l) should be open slats. The storage area 88 further stores a fourth opening pattern P4 indicating that the slats 2 constituting the shutter curtain 3 should be alternately opened slats.

  Furthermore, in the shutter device 1 of the present embodiment, the user arbitrarily selects any one of the opening patterns P (P1 to P4) held in the storage area 88 of the ECU 85 by operating the input device 87. It is possible to do. Then, the ECU 85 of the present embodiment selectively sets each slat 2 (2a to 2l) constituting the shutter curtain 3 to the open posture based on the opening pattern P of each slat 2 selected by this operation input. Accordingly, the operation of the lifting device 5 and the first attitude control device 35 is controlled (selective release control).

  Specifically, as shown in the flowchart of FIG. 19, when the ECU 85 of the present embodiment detects an operation input to the input device 87 based on the operation input signal Sc (step 101: YES), the operation input is subsequently performed. It is determined whether or not it is required to shift to the selective release mode in which each slat 2 is selectively opened (step 102). In the present embodiment, the request to shift to the selective release mode is made by selecting any of the release patterns P (P1 to P4) by an operation input to the input device 87. If the operation input indicated by the operation input signal Sc is a request for shifting to the selective release mode (step 102: YES), the ECU 85 stores the release pattern P selected by the operation input. By reading from the area 88, an open slat to be held in the open posture is specified (step 103).

  In addition, the ECU 85 of the present embodiment acquires the external environment information Ie (step 104), and whether or not the selected opening pattern P is compatible with the external environment where the shutter device 1 is placed. Is determined (step 105). In this embodiment, the external environment suitability determination in step 105 is performed based on whether or not each state quantity such as the outside air temperature and the wind speed acquired as the external environment information Ie does not exceed a predetermined threshold value. Based on. When the ECU 85 according to the present embodiment determines that the selected opening pattern P is compatible with the external environment (step 105: YES), the ECU 85 is activated by the operation of the elevating device 5 and the first attitude control device 35. The selective release control for each slat 2 is executed (step 106).

  If the ECU 85 of this embodiment determines that the selected opening pattern P is not suitable for the external environment in step 105 (step 105: NO), the ECU 85 does not execute the process of step 106.

  If the operation input indicated by the operation input signal Sc does not require the shift to the selective release mode in step 102 (step 102: NO), the ECU 85 determines that each of the operation inputs that constitute the shutter curtain 3 is performed. It is determined whether or not it is required to shift to an opening adjustment mode in which the opening of the slat 2 can be adjusted (step 107). When the operation input requests to shift to the opening adjustment mode (step 107), the opening adjustment control of each slat 2 is executed by the operation of the lifting device 5 and the second attitude control device 60. (Step 108).

  If the operation input indicated by the operation input signal Sc does not require the shift to the opening adjustment mode in step 107 (step 107: NO), the ECU 85 of the present embodiment Normal lift control by operation is executed (step 109). If no operation input to the input device 87 is detected in step 101 (step 101: NO), the processing in steps 102 to 109 is not executed.

  More specifically, as shown in the flowchart of FIG. 20, the ECU 85 of the present embodiment first determines whether or not the second attitude control device 60 is in the on-operation state when performing the selective release control of each slat 2. Is determined (step 201). When the second posture control device 60 is in the on-operation state (step 201: YES), the position where the second posture control device 60 is in the off state, that is, the locking of the locking pin 58 is released. Thus, the shutter curtain 3 is lowered by the operation of the elevating device 5 until each slat 2 returns to the closed posture (see FIG. 16) (step 202).

  Further, when the second attitude control device 60 is in the OFF operation state (step 201: NO), the ECU 85 of the present embodiment next determines whether or not the closed slat in the selected release pattern P is in the open attitude. Is determined (step 203). Further, the ECU 85 determines from the posture control section X1 by the first posture control device 35 that the first open slat disposed at the lowermost position among the open slats in the selected open pattern is set above the partition wall 33. Is also determined to be in the upper standby position (step 204, see FIG. 7). Then, the ECU 85 of the present embodiment raises the shutter curtain 3 by the operation of the elevating device 5 until all the closed slats are in the closed posture (step 203: NO) and the first open slat reaches the standby position ( Step 205).

  It should be noted that the determination of the closing posture of the closing slat in step 203 is performed by the previous selective opening control with an opening pattern (for example, the second opening pattern P2) different from the selected opening pattern P (for example, the first opening pattern P1). It becomes effective when is performed. Further, in the shutter device 1 of the present embodiment, the slat 2 in the open posture is above the upper end portion of the partition wall 33 or the communication hole 75 provided in the middle of the partition wall 33 as described above. It returns to the closed posture by moving (see FIGS. 7 and 16). And the shutter apparatus 1 of this embodiment becomes the state by which all the shutter curtains 3 were wound up by the winder 22 of the raising / lowering apparatus 5, All the slats 2 which comprise the said shutter curtain 3 ( 2a to 2l) reach the standby position.

  When the ECU 85 of this embodiment determines that the first open slat is in the standby position in step 204 (step 204: YES), the ECU 85 lowers the shutter curtain 3 by operating the lifting device 5 (step 206). Further, the ECU 85 determines whether or not the open slat in the selected open pattern P is in the posture control section X1 by the first posture control device 35 (step 207). When the open slat is in the posture control section X1 (step 207: YES), the first posture control device 35 is operated (ON operation, step 208), and when the open slat is not in the posture control section X1. (Step 207: NO), the first attitude control device 35 is deactivated (off operation, step 208).

  Further, the ECU 85 determines whether or not the shutter curtain 3 that operates to move down has reached the stop position (step 210). Note that the ECU 85 of this embodiment, for example, when the shutter curtain 3 reaches the fully closed position or when an operation input indicating that the lifting / lowering operation of the shutter curtain 3 should be stopped is detected. It is determined that the stop position has been reached. Then, the ECU 85 repeats the processing from step 206 to step 210 until it is determined in step 210 that the shutter curtain 3 has reached the stop position.

  That is, when the first attitude control device 35 is in the ON operation state, the slat 2 that has passed the attitude control section X1 rotates in the opening attitude transition direction, and the engagement protrusion provided at the end in the longitudinal direction. 36 is held in an open posture by engaging with the second passage (see FIG. 7B). In addition, when the first posture control device 35 is in the off-operation state, the engaging projection 36 of the slat 2 that has passed through the posture control section X1 maintains the closed posture without rotating, and the engaging protrusion 36 enters the first passage. By being engaged, the closed posture is maintained (see FIG. 7A). In the shutter device 1 of the present embodiment, when it is determined that the shutter curtain 3 has reached the stop position (step 210: YES), the ECU 85 stops the operation of the lifting device 5 (step 211). Based on the opening pattern P selected by the operation input, each slat 2 can be selectively set to the opening posture.

As described above, according to the present embodiment, the following effects can be obtained.
(1) The partition wall 33 that divides the guide passage 24 of the guide rail 4 into a first passage 31 and a second passage 32 is provided with a communication hole 75 that connects the first passage 31 and the second passage 32. The communication hole 75 is formed with a guide surface 80 s of the engaging protrusion 36 that descends in the second passage 32 by extending downward from the upper end portion 75 a of the communication hole 75 and has a distal end. A guide wall 80 is provided with the 80a side projecting into the second passage 32.

  According to the above configuration, the engaging protrusion 36 that engages with the second passage 32 can be moved to the first passage 31 side via the communication hole 75 formed in the partition wall 33. That is, as the shutter curtain 3 moves up, the engaging projection 36 that engages with the second passage 32 reaches the site where the communication hole 75 is formed and is biased by the torsion coil spring 34 that constitutes the biasing member. The slat 2 is allowed to rotate. Thus, the slat 2 held in the open posture can be returned to the closed posture with a smaller ascending operation of the shutter curtain 3 without moving to the upper end of the partition wall 33.

  Further, when the shutter curtain 3 is lowered, the engagement protrusion 36 that engages with the second passage 32 slides on the guide surface 80 s formed by the guide wall 80 so that the formation portion of the communication hole 75 is formed. Move from top to bottom. Further, the engagement protrusion 36 is separated from the guide surface 80 s formed by the guide wall 80 on the tip 80 a side protruding into the second passage 32. And thereby, before the engaging protrusion 36 engaged with the 2nd channel | path 32 moves to the 1st channel | path 31 side via the communication hole 75, the formation site | part of the communication hole 75 can be passed.

  Therefore, according to the above configuration, when the shutter curtain 3 is lowered, the movement of the engaging projection 36 that engages with the second passage 32 toward the first passage 31 can be prevented with a simple configuration. it can. And thereby, the open attitude | position of the slat 2 can be hold | maintained also under the site | part in which the communication hole 75 was formed.

  (2) The guide wall 80 is configured such that the distal end 80 a side can be elastically deformed in the thickness direction of the partition wall 33. By employ | adopting such a structure, the engagement protrusion 36 can be spaced apart from the guide surface 80s which the guide wall 80 forms more smoothly. Further, even when the engaging projection 36 that has reached the site where the communication hole 75 is formed comes into contact with the guide wall 80 during the raising operation of the shutter curtain 3, the impact due to the contact can be reduced. And thereby, the smooth raising / lowering operation | movement of the shutter curtain 3 can be ensured.

  (3) A slope 83 extending from the second passage 32 side to the first passage 31 side is formed at the lower end portion 75b of the communication hole 75 so as to be continuous with the side wall surface 33b of the partition wall 33 on the second passage 32 side. . With such a configuration, even when the engaging protrusion 36 separated from the guide surface 80 s formed by the guide wall 80 enters the communication hole 75 from the second passage 32 side, the communication is performed. By coming into contact with the inclined surface 83 formed at the lower end portion 75b of the hole 75, the hole 75 moves in a manner of sliding on the inclined surface 83 below the lower end portion 75b. As a result, it is possible to more reliably prevent the engagement protrusion 36 that engages with the second passage 32 from moving toward the first passage 31 when the shutter curtain 3 is lowered.

  Further, when the shutter curtain 3 is lifted, the engaging protrusion 36 that engages with the second passage 32 enters the communication hole 75 while being guided by the slope 83. As a result, the engaging projection 36 can be moved from the second passage 32 side to the first passage 31 side more smoothly.

  (4) The guide wall 80 is provided at a position where the guide surface 80 s is continuous with the side wall surface 33 b on the second passage 32 side in the partition wall 33. With such a configuration, the guide wall 80 forms the engaging protrusion 36 that engages the second passage 32 more smoothly at the portion where the communication hole 75 is formed when the shutter curtain 3 is lowered. Guidance can be provided along the guide surface 80s.

  (5) The shutter device 1 includes an ECU 85 that controls the operation of the posture control device 35 so as to selectively open each slat 2. The storage area 88 of the ECU 85 has a plurality of opening patterns indicating combinations of slats 2 (open slats) to be held in an open position and slats 2 (closed slats) to be held in a closed position by the operation of the first attitude control device 35. P (P1 to P4) is held. Further, the ECU 85 reads the opening pattern P selected by the operation input to the input device 87 from the storage area 88, thereby specifying the opening slat in the opening pattern P. Further, the ECU 85 determines whether or not the open slat in the selected open pattern P is descending the posture control section X1 set above the partition wall 33. Then, the ECU 85 operates (turns on) the posture control device 35 when the open slat descends the posture control section X1 (selective release control).

  According to the said structure, each slat 2 can be selectively hold | maintained in an open posture by arbitrary combinations. And the opening part of the shutter curtain 3 can be formed in the optimal position according to a use condition by switching the open pattern.

  (6) The ECU 85 determines whether or not the opening pattern of each selected slat 2 is compatible with the external environment where the shutter device 1 is placed. When it is determined that the selected release pattern is compatible with the external environment, the selective release control is executed.

  According to the above configuration, for example, when the slats 2 are shifted to the open posture at a low temperature or during a strong wind, it is possible to prevent a sudden change in the indoor environment caused by the raising operation of the shutter curtain 3.

[Second Embodiment]
Hereinafter, a second embodiment relating to a residential shutter device will be described with reference to the drawings. For convenience of explanation, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIGS. 21A to 21F, the shutter device 1 of the present embodiment has a communication hole 75B formed in the partition wall 33 and the communication hole 75B in comparison with the first embodiment. The guide member 81 </ b> B provided in the above, specifically, the configuration of the guide wall 80 </ b> B is different.

  Specifically, the guide member 81B of the present embodiment has a guide wall 80B that extends upward from the lower end portion 75b of the communication hole 75B to close the communication hole 75B. In the present embodiment, the slope 83 as in the first embodiment is not formed at the lower end 75b of the communication hole 75B. Also in the present embodiment, the guide wall 80B is arranged in a manner continuous with the side wall surface 33b on the second passage 32 side in the partition wall 33, so that the guide wall 80B descends in the second passage 32. The guide surface 80s of the protrusion 36 is formed.

  Moreover, the guide member 81B of this embodiment is integrally formed using resin like the guide member 81 in the said 1st Embodiment including the guide wall 80B. Then, the guide member 81B of the present embodiment is pressed by the engaging protrusion 36 that is in contact with the guide wall 80B based on the biasing force of the torsion coil spring 34, so that the tip 80a side of the guide wall 80B is in contact with the guide wall. It is configured to tilt toward the first passage 31 side (right side in each figure) in a manner of being bent from the base end portion of 80B.

  That is, as shown in FIGS. 21A to 21C, the engaging protrusion 36 that engages with the second passage 32 during the lowering operation of the shutter curtain 3 is the guide wall as in the first embodiment. The part where the communication hole 75B is formed is moved from the upper side to the lower side while sliding on the guide surface 80s formed by 80B. At this time, the tip 80a side of the guide wall 80B pressed against the second passage 32 based on the urging force of the torsion coil spring 34 tilts toward the first passage 31 side (right side in FIG. 21). A gap communicating between the first passage 31 and the second passage 32 is formed in the vicinity of the upper end portion 75a of the hole 75B.

  However, the engaging protrusion 36 that slides from the upper side to the lower side on the guide surface 80s formed by the guide wall 80B is located on the second passage 32 side through a gap formed on the tip 80a side of the guide wall 80B. Cannot move to the first passage 31. Thus, the shutter device 1 of the present embodiment is configured such that the open posture of each slat 2 is maintained even below the portion where the communication hole 75B is formed.

  On the other hand, as shown in FIGS. 21D to 21F, when the shutter curtain 3 is lifted, a gap formed on the tip 80a side of the guide wall 80B due to the tilt of the guide wall 80B is a second passage. It is located above the engaging protrusion 36 that rises in the position 32, that is, on the front side in the moving direction. In the present embodiment, the engaging protrusion 36 moves from the second passage 32 side to the first passage 31 side through a gap formed in the vicinity of the upper end portion 75a of the communication hole 75B. In other words, by allowing the slat 2 to rotate based on the urging force of the torsion coil spring 34, the slat 2 held in the open posture can be quickly returned to the closed posture.

  Note that the guide member 81B of the present embodiment includes a stopper portion 90 that can restrict the tip 80a side of the guide wall 80B from tilting toward the second passage 32 by contacting the tip 80a of the guide wall 80B. Yes. Then, by more reliably preventing the engagement protrusion 36 that engages the first passage 31 from moving toward the second passage 32, the slats 2 can be closed more stably. It is a configuration that can be maintained.

In addition, you may change each said embodiment as follows.
In each of the above embodiments, each slat 2 (2a to 2l) is provided with the engaging protrusion 36 (36B) and the locking pin 58 as the locking protrusion. The structure including the slat 2 in which either or both of the locking pins 58 are not provided may be employed. That is, it is not always necessary that all the slats 2 constituting the shutter curtain 3 can be changed in posture with the support shaft 12 as a rotation center.

  For the attitude control device (first attitude control device) 35, when each slat 2 descends a predetermined section (posture control section X1) set above the partition wall 33, the operation state changes accordingly. The configuration may be arbitrarily changed as long as the slat 2 passing through the section is rotated.

  Further, the configuration of the second attitude control device 60 may be arbitrarily changed. For example, the structure which rotates the latching member 63 directly using the actuator which uses a motor as a drive source may be sufficient. Further, the locking pin 58 of each slat 2 may be engaged with the locking groove 62 of the locking member 63 when the shutter curtain 3 is lowered. And each slat 2 may be rotated by the structure other than making the said latching pin 58 into a rotation fulcrum by latching the latching pin 58. FIG.

  In each of the above embodiments, each slat 2 is rotationally urged in the closing posture return direction based on the urging force of the torsion coil spring 34 fitted and inserted into the shaft-like member 13 serving as the rotational axis. However, the biasing member may be arbitrarily changed, for example, using an elastic member other than the torsion coil spring.

The communication hole 75 may be formed at a plurality of locations on the partition wall 33.
In the first embodiment, when the shutter curtain 3 is lifted, the guide wall against the engaging projection 36 that moves from the second passage 32 side to the first passage 31 side through the communication hole 75. 80 was determined not to interfere. However, the present invention is not limited to this, and after the contact with the tip 80a of the guide wall 80 protruding into the second passage 32, the engaging projection 36 moves from the second passage 32 side to the first passage 31 side. There may be.

  In the first embodiment, the guide wall 80 is made of resin. However, the present invention is not limited to this, and may be formed of other materials such as metal. The tip 80a side is not necessarily configured to be elastically deformable.

  In addition, the slope 83 is not necessarily formed on the lower end portion 75 b of the communication hole 75. The guide surface 80 s formed by the guide wall 80 does not necessarily have to be continuous with the side wall surface 33 b on the second passage 32 side in the partition wall 33.

  -About the control aspect of the shutter apparatus 1, you may change arbitrarily. For example, the configuration may be such that the selective opening control of each slat 2 can be executed with an opening pattern P other than the first to fourth opening patterns P1 to P4 illustrated in FIG. In addition, when it is determined that the opening pattern P selected by the operation input is suitable for the external environment, the selection opening control is executed. However, a configuration in which such an environment suitability determination is not performed may be used. And when the selected opening pattern is not suitable for an external environment, it may be configured to notify that.

-Moreover, ECU85 selects the open pattern according to the external environment. And it is good also as a structure by which the selective release control of each slat 2 is performed automatically by this.
For example, as shown in the flowchart of FIG. 22, the ECU 85 also acquires the external environment information Ie (step 310) even when an operation input to the input device 87 is not detected (step 301: NO). Further, the ECU 85 determines whether or not the external environment indicated by the external environment information Ie satisfies a condition set in advance as an environment in which the selective release control of each slat 2 is to be automatically executed (automatic control). Execution determination, step 311). Further, when it is determined in step 311 that automatic control should be executed (step 311: YES), the ECU 85 automatically sets the release pattern P that is associated in advance as corresponding to the external environment indicated by the external environment information Ie. (Step 312). The ECU 85 may be configured to automatically perform selective release control of each slat 2 by reading the automatically selected release pattern P from the storage area 88 (step 303) (step 306). In the flowchart shown in FIG. 22, the processes in steps 301 to 306 (309) are the same as the processes in steps 101 to 6 (109) in the flowchart shown in FIG.

  Furthermore, even when the selective opening control of each slat 2 is started based on the operation input to the input device 87, the ECU 85 may automatically determine the opening pattern P according to the external environment. The automatic opening control of each slat 2 by the ECU 85 as described above may be performed by opening adjustment control by the second attitude control device.

Further, the configuration of the selective opening control device that selectively shifts each slat 2 to the open posture (see FIG. 17, the electrical configuration of the shutter device 1) may be arbitrarily changed.
Specifically, any one of a position detection unit (ECU 85, pulse sensor 86) for detecting the raising / lowering operation position of each slat 2, a storage unit (storage area 88 of the ECU 85) for holding the opening pattern P, and each opening pattern P is selected. You may change arbitrarily the structure of the open selection part (input device 87, ECU85) to select. Each process corresponding to the determination unit that determines whether or not the open slat is descending the posture control section X1 and the selection operation control unit that operates the posture control device 35 based on the determination (see FIG. 20, step 207). The specific contents of step 209) and the execution subject (ECU 85) may be arbitrarily changed. Further, specific processing (refer to FIG. 19, step 104 and step 105) corresponding to the conformity determination unit that determines whether or not the selected opening pattern P conforms to the external environment where the shutter device 1 is placed. The contents and the execution subject (ECU 85) may be arbitrarily changed. The specific contents of each process (see FIG. 22, step 310 to step 312) corresponding to the automatic selection unit that selects the open pattern P based on the external environment and the execution body (ECU 85) are also arbitrarily changed. May be.

  In the second embodiment, the guide wall 80B is formed using a resin. And it decided to incline to the 1st channel | path 31 side in the aspect in which the front-end | tip 80a side is bent from the base end part of the said guide wall 80B. However, the present invention is not limited to this, and the configuration of the guide member 81 may be arbitrarily changed, including the material of the guide wall 80B. For example, a joint is provided on the proximal end side of the guide wall 80B, and a biasing member that biases the distal end 80a side of the guide wall 80B toward the second passage 32 side is provided. And it is good also as a structure which can incline the front-end | tip 80a side of the guide wall 80B to the 1st channel | path 31 side against the biasing force.

Next, technical ideas that can be grasped from the above embodiments will be described.
(A) The shutter device, wherein the guide wall is provided at a position where the guide surface is continuous with the side wall surface on the second passage side. Thereby, at the time of the descent operation of the shutter curtain, the engaging protrusion that engages with the second passage can be guided more smoothly along the guide surface formed by the guide wall at the site where the communication hole is formed.

  (B) The selective opening control device includes a matching determination unit that determines whether or not the selected opening pattern matches the external environment of the shutter curtain.

  According to the above configuration, when the selected opening pattern is adapted to the external environment, the slat is shifted to the opening posture, or measures such as notifying that the selected opening pattern does not enter the external environment are taken. It becomes possible to take. Thus, for example, when the slats are moved to the open posture, for example, when the temperature is low or when the wind is strong, it is possible to prevent a sudden change in the indoor environment caused by the raising operation of the shutter curtain.

(C) The shutter selection unit includes an automatic selection unit that selects the release pattern based on the external environment.
According to the above configuration, it is possible to automatically select the opening pattern corresponding to the external environment and appropriately shift each slat to the opening posture. As a result, the convenience of the user can be improved.

  (D) The guide wall is formed so as to be elastically deformable in the thickness direction of the partition wall, and is configured to tilt toward the first passage based on the biasing force. Shutter device. Thereby, with a simple configuration, it is possible to form a guide member capable of moving the engaging protrusion engaging with the second passage toward the first passage when the slat is raised.

  (F) The shutter device, wherein the guide member is provided with a stopper portion that restricts the tilt of the guide wall toward the second passage. Thereby, the movement to the 2nd channel | path side of the engagement protrusion part engaged with a 1st channel | path can be prevented more reliably. As a result, the closed posture of the slat can be maintained more stably.
