The shutter device of Patent Document 1 includes a plurality of long plate-like slats extending in the horizontal direction and arranged in parallel in the vertical direction. Link members of the same length as the vertical width of each slat are attached to both ends of each slat, and a plurality of slats are arranged in parallel in the vertical direction by connecting adjacent link members in the vertical direction. The Each slat is pivotally supported by link members attached to both ends, and each slat is rotatable independently.

  As in the first patent document, the shutter device of Patent Document 2 is provided with link members on both ends of each slat so that the slat is pivotally supported. In addition, at both ends of each slat, guided pins that protrude in parallel with the rotation center are provided at positions shifted downward from the rotation center. A main guide passage extending in the vertical direction and a sub guide passage provided in parallel to the main guide passage are provided at both side edges of the opening of the building where the shutter device is provided. When the slat is pulled out from the winding body, the link member having the center of rotation of the slat is introduced into the main guide passage and slides in the main guide passage, and the guided pin is introduced into the sub guide passage.

The left and right connecting body guide paths 3L and 3R extend in the vertical direction to the left and right side edges OPL and OPR of the opening OP, and as shown in FIGS. It is formed in the vertical frames 30L and 30R. Since the left and right vertical frames 30L and 30R are symmetrical and have the same structure, in the present embodiment, the left left vertical frame 30L will be described as a representative.

  As shown in FIG. 10, the left vertical frame 30L is formed in a rectangular cross section, and includes an upper and lower opening 31, a hollow 32, and connecting ribs 33a and 33b. A left connecting body guide path 3L on which the left link connecting body 5L is slidably guided and supported is formed in the upper and lower opening 31 where the right side of the left vertical frame 30L is open. Two pairs of support ribs 34a and 34b project from the inner wall of the left connected body guideway 3L so as to face the inside of the opening OP of the building ST. A thin groove-like lubricating member (not shown) that smoothly slides the left link connecting body 5L extends in the vertical direction on the inner wall of the left connecting body guide path 3L. On the left side of the left connecting body guide path 3L, a hollow portion 32 that is adjacently surrounded by front, rear, left, and right walls is formed. Connecting ribs 33a and 33b project from the left rear side of the hollow portion 32 and the rear side of the upper and lower opening 31, and are configured to be connectable to the vertical frame of the sash frame SF. As shown in FIG. 10, the outer right end edge of the upper and lower openings 31 of the left vertical frame 30L is formed by extending a left slat open wall 4L with which a projection member 21b described later abuts in the vertical direction. The left slat open wall 4L is provided in parallel to the left connecting body guide path 3L provided at the left edge OPL of the opening OP of the building ST. The right vertical frame 30R is symmetrically formed with the left vertical frame 30L and has the same structure.

  The left vertical frame 30L has a lower end portion fixed by a dish plate member (not shown). The dish plate member is a member that extends in the left-right direction at the lower end of the opening OP of the building ST, and is formed continuously with, for example, a not-illustrated dish plate member of the sash frame SF. As shown in FIG. 7, the left vertical frame 30 </ b> L has an upper end opening 35 at the upper end, and the left link connecting body 5 </ b> L enters the left connecting body guide path 3 </ b> L from the upper end opening 35.

The right vertical frame 30R is similarly configured.

(Casing, winding body)
The upper ends of the right vertical frame 30R and the left vertical frame 30L are connected to the casing 7 of the winding body 6 by unillustrated brackets and screws, respectively. As shown in FIGS. 1, 2, and 7, the casing 7 is formed in a box shape having a rectangular cross section, and rotates a shaft-shaped winding body 6 that extends horizontally in the left-right direction via a bearing (not shown). Hold it possible. The casing 7 is provided with a lower opening 7a on the lower surface that extends to the left and right with a predetermined width and opens downward. When the wound left and right link connectors 5L, 5R and the plurality of slats 2 are pulled out, they are separated from the winder 6 and pulled downward via the lower opening 7a. When the winding operation is performed, the left and right link connectors 5L and 5R and the plurality of slats 2 are wound through the lower opening 7a.

  As shown in FIG. 1, the casing 7 is provided with a motor 15. The motor 15 winds the slat 2 and the left and right link coupling bodies 5L and 5R in a direction (forward direction) to wind the slat 2 and the left and right link coupling bodies 5L and 5R around the winding body 6 via a reduction gear (not shown). The winding body 6 can be rotated in both forward and reverse directions in a direction (reverse direction) that is peeled off and pulled out from the body 6. The forward / reverse rotation is switched by a switch (not shown), and the motor 15 is driven or stopped by turning on / off a drive switch (not shown).

  In the casing 7, an inclined guide member 8 having an inclined surface 8a inclined downward toward the lower opening 7a is disposed at a position corresponding to the position HP where the slat 2 is peeled off, as shown in FIG. ing. The inclined guide member 8 is formed of, for example, a hard resin member, and is disposed so as to extend in the left-right direction along the front side edge of the lower opening 7 a of the casing 7. The inclined guide member 8 has a substantially trapezoidal cross section. This trapezoid is a so-called right-angled trapezoid having a right-angled corner in one place, and is arranged so that opposing parallel side portions of a trapezoidal cross section extend in the vertical direction. The inclined guide member 8 forms an inclined surface 8a in which a portion corresponding to the trapezoidal oblique side is inclined downward from the outside to the inside. The inclined surface 8a is arranged so as to correspond to the lower circumferential portion of the winding body 6, and a shallow concave curved surface is formed on the surface of the inclined surface 8a. The inclined guide member 8 has an R portion 8b formed by rounding an acute angle apex formed by the inclined surface 8a and one parallel side portion. As shown in FIGS. 11 and 14, the left and right end portions inside the casing 7 are adjacent to the rear side at both ends of the inclined guide member 8 (FIG. 14 is shown by a left vertical frame 30L). ), Respectively, a rotation posture switching member 9 is provided.

(Rotating posture switching member)
The position at which the rotation posture switching member 9 is provided is between the position HP where the left and right link coupling bodies 5L and 5R are peeled from the winding body 6 and the upper end opening 35 of the left and right coupling body guide paths 3L and 3R. It is provided in a certain transition area 7B. As shown in FIGS. 11 and 14, the rotation posture switching member 9 is formed, for example, from a hard resin member with a width slightly longer than a protruding member 21 b (described later) and in a substantially right-angled cross section. The rotation posture switching member 9 is provided with a top portion 9a adjacent to an inner lower end portion of the inclined surface 8a of the inclined guide member 8. The rotation posture switching member 9 includes a first inclined surface 9b that is inclined from the outer top portion 9a toward the upper end opening 35, and a second inclined surface that is continuous with the first inclined surface 9b and has a larger inclination angle than the first inclined surface 9b. And a surface 9c. The inner lower end of the second inclined surface 9 c is adjacent to the outer opening edge of the upper end opening 35. By making the inclination angle of the second inclined surface 9c larger than that of the first inclined surface 9b, the inclination of the left and right link connecting bodies 5L, 5R is increased when entering the connecting body guide path 3L, This makes it easy to enter 3R. For example, as shown in FIG. 14, the rotation posture switching member 9 can be moved in the left-right direction along the slat open walls 4L, 4R of the left and right vertical frames 30L, 30R by an electromagnetic actuator 9d as a drive device. Is provided. When the rotation posture switching member 9 moves to the right side (left side of the right vertical frame 30R) in the left vertical frame 30L, it is positioned at the operating position AA located in the transition region 7B (see FIG. 14), and the left vertical frame 30L Is moved to the left position (right side in the right vertical frame 30R), it is positioned at the retracted position DA retracted from the transition area 7B (see FIG. 10). The operation of the electromagnetic actuator 9d and the switching of the operation direction are performed by an operation switch (not shown).
When the rotation posture switching member 9 is in the operation position AA, when the left and right link members 11L and 11R enter the left and right connecting body guide paths 3L and 3R from the upper end opening 35, the rotation slat 21 is The inclined guide member 8 deviates from the inclined surface 8a. However, a protrusion member 21b, which will be described later, of the rotating slat 21 comes into contact with the first inclined surface 9b and the second inclined surface 9c of the rotating posture switching member 9. Therefore, the rotating slats 21 supported by the left and right link members 11L and 11R maintain the closed posture, and the protruding member 21b is connected to the connecting body guide paths 3L and 3R from the upper end opening 35 by the rotating posture switching member 9. Be guided to. Then, the rotating slat 21 maintains the closed posture by bringing the protruding member 21b into contact with the housing concave groove 11d of at least one link member 11L and the outer inner surface 3a of the coupling body guide path 3L.
When the rotation posture switching member 9 is in the retracted position DA, when the left and right link members 11L and 11R enter the left and right connecting body guide paths 3L and 3R from the upper end opening 35, the rotation slat 21 is The inclined guide member 8 deviates from the inclined surface 8a. Then, the rotating slat 21 is rotated so that the center of gravity G is positioned below and is in an open posture. Next, the rotating slat 21 maintains the open posture by bringing the protruding member 21b into contact with the outer surface 4a of the slat open wall 4L.

(Slat link link)
The slat 2 is a long plate-like member that is formed from, for example, an aluminum alloy shaped member and extends in the left-right direction. It is formed to be slightly curved so that the central portion on the outdoor side is convex in the vertical width direction. As shown in FIGS. 3 and 4, the slat 2 is provided with separate link members 11 (described later) at both ends, a rotatable slat 21 that can rotate, and a normally closed slat 22 that always takes a closed posture. It has. Left and right normally closed link portions (left and right link members) 22a provided in pairs on both sides are integrally connected to each other by normally closed slats 22 extending therebetween. The left and right link members 11L and 11R and the left and right normally closed link portions 22a are connected in a chain by an upper connecting shaft 13u and a lower connecting shaft 13d, which will be described later, to form left and right link connectors 5L and 5R ( (See FIG. 5 and FIG. 6). The left and right link coupling bodies 5L, 5R enter the left and right coupling body guide paths 3L, 3R from the upper end opening 35 and are guided and supported so as to be slidable in the vertical direction, respectively (see FIG. 7).

(Rotating slats)
As shown in FIGS. 3, 4, and 5, the rotating slat 21 includes a rotating slat main body 21 a and a protrusion that is fixed to both ends of the rotating slat main body 21 a and protrudes toward the left link member 11 </ b> L. And a protruding member 21b. As shown in FIG. 7, a first upper engaging hook portion 21c extending in the left-right direction is formed at the upper end portion of the rotating slat main body portion 21a. The first upper engagement hook portion 21c is formed in a cross-sectional shape that is open at the outer side and is rounded with a predetermined width from the tip. The first upper engaging hook portion 21c has a tip protrusion 21d formed at the upper end of a curved outer peripheral portion having a bowl-shaped cross section. The lower end of the rotating slat 21 is provided with a first lower end rib 21e extending in the left-right direction and projecting indoors. The first lower end rib 21e fills a gap with the upper end portion of the normally closed slat 22 adjacent to the lower side, and improves the weight balance of the rotating slat 21 and the rigidity of the rotating slat 21. A tapping screw hole 21f is provided at a position one third of the width of the rotating slat 21 in the width direction. The tapping screw hole 21f extends in the left-right direction. In addition to the role of screwing the protruding member 21b, the tapping screw hole 21f is formed by a thin plate-like member. It also serves to improve rigidity. The center of gravity G of the rotating slat 21 is located at a substantially central portion in the width direction of the rotating slat 21. When the rotating slat 21 is engaged with a later-described second lower engaging hook portion 22e of the normally closed slat 22 by the first upper engaging hook portion 21c, the rotating slat 21 is in a free state (the lower end of the rotating slat 21). When the edge 21g is not in contact with any of them, the rotating slat 21 is suspended from the second lower engagement hook portion 22e engaged with the first upper engagement hook portion 21c and is in a substantially vertical position. Positioned. The rotating slat 21 is positioned in a substantially vertical position, and is oriented to take an open posture.

  The lower end edge 21g of the rotating slat 21 has a second upper engaging hook portion 22c which is a lower portion than the tip projection 22d which is the upper end portion of the normally closed slat 22 adjacent to the lower portion when a closed posture described later is taken. It is comprised so that it may contact | abut to the engagement edge 22c1 from the outer side (refer FIG. 11 and FIG. 12). Even if the lower end portion of the rotating slat 21 and the upper end portion of the normally closed slat 22 are not fitted to each other, the lower end edge 21g of the rotating slat 21 abuts on the second upper engaging hook portion 22c of the normally closed slat 22. Thus, the rotation of the rotating slat 21 to the inside is restricted, and a strong resistance force against the pressing force from the outside is generated on the rotating slat 21.

As shown in FIGS. 3 and 4, the protruding member (protruding portion) 21 b is formed of, for example, a hard resin member and includes a covering portion 21 b 1 that covers a part of the end of the rotating slat 21, and a covering portion 21 b 1. A cylindrical portion 21b2 that protrudes toward the left link member 11L is provided (the left end portion of the rotating slat 21 is shown in FIGS. 3, 4, and 5). The cylindrical portion 21b2 has an opening 21b3 on the left link member 11L side, and the bottom of the cylindrical portion 21b2 is coaxial with the tapping screw hole 21f (see FIG. 7) and has a smaller diameter than the opening 21b3 on the left link member 11L side. Through-holes (not shown) are provided. A protruding member 21b that protrudes toward the right link member 11R is similarly provided at the right end of the rotating slat 21.
The protruding member 21b is fixed to both ends of the rotating slat 21 by a tapping screw (not shown) inserted through the opening 21b3 of the cylindrical portion 21b2 and penetrating through the through hole. Note that the protruding member 21b is guided to the connecting body guide paths 3L and 3R together with the left and right link members 11L and 11R without engaging both ends of the rotating slat 21 with the left and right connecting body guide paths 3L and 3R. Slide up and down. When the rotating slat 21 takes an open posture, which will be described later, as shown in FIGS. 9 and 10, in the protruding member 21b, the cylindrical portion 21b2 comes into contact with the outer surface 4a of the slat open walls 4L and 4R. When the rotating slat 21 takes a closed posture, which will be described later, as shown in FIGS. 13 and 14, it enters the left and right connecting body guide paths 3L, 3R together with the link member 11 which will be described later, and the outer surface of the link member 11 (storage) The inner wall surface 11d1) of the concave groove 11d and the outer inner surfaces 3a of the left and right connecting body guide paths 3L and 3R (the surface of the lubricating member not shown) are in contact.

(Link member)
The link member 11 includes a left link member 11L and a right link member 11R that are paired symmetrically. As shown in FIGS. 3, 4, and 6, the left link member 11 </ b> L is disposed at the left end of the rotating slat 21 on the left vertical frame 30 </ b> L side. The right link member 11 </ b> R is similarly disposed at the right end of the rotating slat 21. The rotating slat 21 is indirectly supported by the left and right link members 11L and 11R via a normally closed slat 22 described later. The left and right link members 11L and 11R are plate-like members formed from, for example, an aluminum alloy shaped member. An upper engagement link hook portion 11 a extending in the left-right direction is formed on the upper end portion of the link member 11, and the upper engagement link hook portion 11 a is connected to the first upper engagement hook portion 21 c of the rotating slat 21. The cross-sectional shape. The upper engagement link hook portion 11a has a tip protrusion 11e formed at the upper end of the curved outer peripheral portion having a bowl-shaped cross section. Lower engaging link hook portions 11b extending in the left-right direction are formed at the lower ends of the left and right link members 11L, 11R. The lower engagement link hook portion 11b is formed in the shape of a bowl-shaped cross section that is open on the indoor side and is curved with a predetermined width from the tip. The lower engaging link hook portion 11b has a rounded bowl-shaped tip portion 11f that is rounded. A lower end link rib 11c that extends in the left-right direction and protrudes indoors is formed adjacent to the upper portion of the hook-shaped portion having a hook-like cross section of the lower engagement link hook portion 11b. The lower end link rib 11c is configured so that when a second upper engagement hook portion 22c (described later) of the normally closed link portion 22a of the normally closed slat 22 is engaged, a force compressing in the vertical direction is generated. This prevents the disengagement between the left and right link members 11L, 11R and the normally closed link portion 22a integral with the normally closed slat 22 by abutting against the tip protrusion 22d (described later). A storage groove 11 d that is recessed in a groove shape when viewed from the outdoor side is provided at a position one third of the upper end in the vertical width direction of the link member 11 so as to extend in the left-right direction. When the rotating slat 21 is positioned on the same plane as the link member 11 (closed posture), the storage concave groove 11d stores the protruding member 21b without protruding from the outermost surface of the link member 11 on the outermost side.

(Normally closed slats)
The normally closed slats 22 extend between a pair of left and right normally closed link portions 22a, and integrally connect the left and right normally closed link portions 22a. Further, as shown in FIGS. 3 and 4, the normally closed slat 22 and the normally closed link portion 22 a are formed of a cross-sectional shape having the same shape as the left and right link members 11 </ b> L and 11 </ b> R arranged on both sides of the rotating slat 21. ing. As shown in FIG. 6, the normally closed slat 22 includes a second upper engagement hook portion 22c having the same shape as the upper engagement link hook portion 11a, and includes a tip protrusion 22d. The normally closed link portion 22a includes a normally closed upper link hook portion 22ac having the same shape as the upper engaging link hook portion 11a, and includes a tip protrusion 22ad.

(Operation of shutter device)
Next, the operation of the shutter device 1 will be described separately when the rotating slat 21 takes an open posture and when the rotating slat 21 takes a closed posture. 7 and 11, only the left side of the left vertical frame 30L, the left link member 11L, the left connecting body guideway 3L, the left link connecting body 5L, etc. is shown, but the right vertical frame is shown. 30R, the right link member 11R, the left connector guide path 3L, and the left link connector 5L operate in the same manner. Therefore, in the description, the description will be made assuming that it is operating on both the left and right sides.

  First, the slat 2 and the left and right link connectors 5L and 5R are wound around the winding body 6. A seat plate (not shown) provided at the lower end of the slat 2 is positioned at the lower end of the casing 7. The lower end portions of the left and right link connecting bodies 5L and 5R are locked in a state of being guided by the upper end portions of the left and right connecting body guide paths 3L and 3R.

  When the rotating slat 21 is in the open posture and the shutter device 1 is closed, the user first switches the operation switch to operate the electromagnetic actuator 9d to position the rotating posture switching member 9 at the retracted position DA ( (See FIG. 10).

  Next, the user switches the changeover switch to the reverse rotation mode in which the slat 2 and the left and right link coupling bodies 5L and 5R are pulled out from the winding body 6. Then, the drive switch is turned on to rotate the winding body 6 in the reverse direction.

  At that time, the seat plate has a predetermined weight, and the plurality of slats 2 and the left and right link coupling bodies 5L and 5R are pulled down by the weight. The left and right link coupling bodies 5L and 5R descend while sliding in the left and right coupling body guide paths 3L and 3R. The left and right link connectors 5L and 5R and the plurality of slats 2 are shown in FIG. 7 as the left and right link connectors 5L and 5R descend while sliding in the left and right connector guide paths 3L and 3R. In this way, it is peeled off from the wound body 6.

  The position where the upper end opening portions 35 of the left and right connecting body guide paths 3L and 3R are provided with respect to the position HP separated from the winding body 6 is inclined downward toward the rear side from the position HP separated. In the position. Therefore, the left and right link connectors 5L and 5R move in an inclined state from the position HP to be peeled toward the upper end opening 35. At this time, since the lower end of the rotation slat 21 is not connected anywhere, it is centered on the arc center (horizontal rotation center HC) of the bowl-shaped curved surface of the first upper engagement hook portion 21c by gravity. And rotate clockwise. When the rotating slat 21 is wound around the winder 6, the left and right link members 11L and 11R arranged at both ends of the rotating slat 21 are overlapped in the left-right direction (positioned on the same plane). State). However, the rotating slat 21 rotates with respect to the left and right link members 11L and 11R by the gravity acting on the center of gravity G when it is separated from the winding body 6. The lower end (lower end edge 21g) of the rotating slat 21 abuts on the inclined surface 8a of the inclined guide member 8, and moves smoothly toward the upper end opening 35.

  Next, as shown in FIG. 8, the rotating slat 21 is disengaged from the inclined surface 8a of the inclined guide member 8, and the rotating posture switching member 9 is at the retracted position DA (see FIG. 10), so (Clockwise at 8). The transition area 7B extends from the inclined surface 8a to the upper end opening 35, and the rotation slat 21 is determined to be in an open position or a closed position by the rotation position in the transition area 7B. The left and right link members 11L and 11R corresponding to the rotating slat 21 start to enter the upper end openings 35 of the left and right connecting body guide paths 3L and 3R at the lower ends.

  Further, when the left and right link members 11L and 11R are guided by the left and right connecting body guide paths 3L and 3R, as shown in FIGS. 9 and 10, the rotating slat 21 has the protruding member 21b that has the slat open wall 4L, Abutting on the outer surface 4a of the 4R building ST, the rotating slat 21 is further rotated to maintain the open posture.

It contacts the outer inner surface 3a of the connecting body guide path. The rotating slat 21 is in a closed posture that overlaps with the left and right link members 11L and 11R in the left-right direction (located on the same plane). The rest is the same as in the open posture.

  When the slat 2 and the left and right link coupling bodies 5L and 5R are wound around the winding body 6, the user switches the changeover switch to the forward rotation mode so that the winding body 6 rotates forward. The user turns on the drive switch to drive the motor 15. As shown in FIG. 15, the end of the link member 11 is locked to a locking portion 6 a provided on a part of the outer periphery of the winding body 6, and the winding body 6 is rotated forward (clockwise in FIG. 15).
