Conventionally, for example, a shutter device described in Patent Document 1 has been proposed as a shutter curtain capable of daylighting or ventilation using a slat as a blind.
In this shutter device, a plurality of slats each provided with a fixed wing and a movable wing are connected in the vertical direction, and the movable wing can be opened and closed in a closed state where the shutter curtain closes the opening of the building.

  In this shutter device, a plurality of slats arranged in the vertical direction push the movable wing provided on the lower slat with the upper fixed wing, thereby rotating the lower movable wing to open the fixed wing. Lighting and ventilation can be made through the opening. In addition, the movable wing in the open state can make it difficult to visually recognize the room from the outside.

  In the shutter device described above, the connecting portion between the upper slat and the lower slat and the connecting portion of the movable wing with respect to the fixed wing in each slat are provided with fixing members at both ends, and lower than the upper slat. The slats of the slats are prevented from being laterally displaced, and the movable wings are not laterally displaced relative to the fixed wings of each slat.

  Further, in the shutter device described in Patent Document 2, the opening and closing operation of the slat is stabilized by a link mechanism provided in the guide rail portion that houses the slat end portion. And since the opening angle of a slat is adjusted by moving a link mechanism, the fine opening / closing operation | movement of each slat can be controlled.

European Patent No. 2039871 JP 2009-203605 A

  However, since the shutter device described in Patent Document 2 is configured to link the link mechanism for each slat, a large number of dedicated parts such as a link and its drive mechanism are required for each slat, and the number of parts is extremely large. There was a drawback of increasing the number.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a shutter device that can control the opening / closing operation of a slat using a simple mechanism with few parts.

In the shutter device according to the present invention, a plurality of slats each including a fixed wing provided with an opening and a movable wing capable of opening and closing the opening are connected in the vertical direction, and the movable wing is opened by relative movement of the upper and lower slats. A guide rail portion having a receiving portion for guiding the vertical movement of the end portion of the slat, and a support formed in the receiving portion of the guide rail portion so as to be opposed to the end portion of the movable wing. And at least one of the resistors is characterized in that some of the resistors have a larger contact resistance than the other resistors.
According to the shutter device of the present invention, when the movable wing of the slat is opened, the support portion formed at the end of the slat is in the open state in contact with the resistor provided facing the receiving portion of the guide rail portion. The movable wing can be supported, and in particular, the contact resistance of some of the resistors is large, so that it can be stably held by resisting the opening / closing operation of the support portion of the movable wing in the open state. In addition, by mixing some resistors with high contact resistance and other resistors with low contact resistance as resistors, the movable wings can be reliably held in an open state with a simple configuration, and in the closed state It can easily move up and down because it does not contact the resistor or has little contact.

Moreover, it is preferable that a resistor is a fiber body which consists of a some fiber.
Since the resistor is composed of a plurality of fibers, when the support portion of the movable wing is opened and closed, the fibers are individually displaced so that the resistance during operation is relatively small, and the movable wing and the fiber body are in an open state. The resistance due to the contact is set by a part of the resistors having a large contact resistance.

In addition, fiber bodies are respectively provided along the longitudinal direction of the guide rail portion on the opposing inner surfaces of the receiving portions of the guide rail portion, and some fibers having a large contact resistance are arranged along the longitudinal direction of the guide rail portion. May be.
Since the fiber bodies are respectively provided along the longitudinal direction of the guide rail portion on the inner surface of the guide rail portion facing the receiving portion, the movable wings of the plurality of slats connected in the vertical direction are open, and the support portion is Since some fibers having a large contact resistance are in contact with the fibers arranged in the longitudinal direction and also arranged in the longitudinal direction, the movable wings of each slat in the vertical direction can be reliably held with a large contact resistance. .
A fiber having a large contact resistance is a fiber having a relatively large thickness.

  According to the shutter device of the present invention, when the movable wing of the slat is opened, the support portion formed at the end of the slat is in contact with the resistor provided in the receiving portion of the guide rail portion, and the movable wing is in the open state. Particularly, since the contact resistance of some of the resistors is large, it can be stably held by resisting the vertical movement of the support portion of the movable wing in the open state.

In addition, by mixing some resistors with high contact resistance and other resistors with low contact resistance as a resistor, the movable wing can be held in the open state and not in contact with the resistor in the closed state. It can move up and down easily because there is little contact.
In addition, since it is only necessary to install the resistor in the receiving portion of the guide rail portion, the number of parts can be reduced and the cost can be reduced.

Hereinafter, a shutter device according to an embodiment of the present invention will be described with reference to FIGS.
The shutter device 1 according to the embodiment shown in FIGS. 1 and 2 has a frame 3 formed in an opening 2 of a building, and the frame 3 has a rectangular frame shape with an upper frame 3a, a lower frame 3b, and a pair of left and right vertical frames 3c. Is formed. A shutter unit 6 is installed between the top plate 4 on the upper side of the frame 3 and the upper frame 3a. A pair of guide rail portions 7 are attached to the vertical frames 3c on both sides below the shutter unit 6 in the vertical direction.

  A shaft 8 and a drive motor 9 are installed inside the shutter unit 6, and a shutter curtain 12 in which a plurality of long slats 10 are vertically connected is wound around the shaft 8. When the shutter curtain 12 is rolled up by forward / reverse rotation of the drive motor 9, the opening state of the opening 2 can be obtained, and when the shutter curtain 12 is drawn out and lowered to the lower end, the opening 2 can be closed. The vertical movement of the shutter curtain 12 is guided by the guide rail portion 7 that sandwiches both ends thereof.

  Next, the structure of the shutter curtain 12 will be described with reference to FIGS. The shutter curtain 12 has a plurality of slats 10 connected in the vertical direction so as to be rotatable between an upper end portion and a baseboard 13 at the lower end portion. Each slat 10 includes a fixed wing 15 having an opening 14 and a movable wing 16 that is rotatable with respect to the fixed wing 15. The lower end of the fixed wing 15 of the upper slat 10 and the lower slat 10 are movable. The upper end portion of the wing 16 is connected to be rotatable and is continuous in the vertical direction. 5 and 6, the upper two movable wings 16 are in a closed state in contact with the fixed wing 15, and the lower two movable wings 16 are in an opened state in which the fixed wing 15 is opened. As shown, the movable wing 16 can be stopped and held during the closed state, the open state, or the open operation.

The fixed wing 15 and the movable wing 16 in each slat 10 have a substantially long plate shape that is long in the lateral width direction, and are formed to be curved in an arc shape in a longitudinal sectional view. The fixed wing 15 has an opening 14 formed in an oval shape, and one or a plurality of, for example, three openings 14 are formed separately from each other in the vertical direction. A net may be attached to each opening 14.
In the example shown in this embodiment, as shown in FIGS. 6 and 7, the three openings 14 are formed so as to be biased toward the upper side in the vertical width direction of the fixed wing 15. An array may be formed at intervals. By arranging the plurality of openings 14 of the fixed wing 15 so as to be biased upward, it is difficult to visually recognize the inside of the opening 14 from the outside when the movable wing 16 is held in an open state. The light reflected from the outer surface of the movable wing 16 on the side and the inner surface of the movable wing 16 on the upper side is incident from the opening 14 so that soft light can be collected indoors. The wind can also flow into the room through the plurality of openings 14 from the gap between the movable wing 16 and the fixed wing 15 in the open state, and vice versa.

  As an example, in the slat 10 shown in FIGS. 7A and 7B, the openings 14 having a vertical width of 5 mm are formed at three positions above the lower end of the fixed wing 15 at intervals of 5 mm. The vertical width of the opening 14 was set to 5 mm or less so that even a child's finger could not pass through. Since the lowermost opening 14 is located above the lower end of the movable wing 16 in the open state, safety, light shielding and privacy can be ensured, and the lighting and the softness and amount of wind can be adjusted.

Moreover, a plurality of sets of three openings 14 are formed at predetermined intervals along the lateral width direction (longitudinal direction) of the fixed wing 15.
In addition, the movable wing 16 has a body portion 16a formed in the central region in FIG. 5 and having a length in the vertical width direction substantially the same as the fixed wing 15 and capable of opening and closing the opening 14 of the fixed wing 15; The support part 16b which is notched and has a small length in the vertical width direction is formed. Then, both end portions of the fixed wing 15 and both narrow support portions 16b of the movable wing 16 are inserted into the guide rail portions 7 on both sides to be guided in the vertical movement.

Next, the connection structure of the plurality of slats 10 will be described with reference to FIGS. The connection structure of the plurality of slats 10 has the same configuration on the left and right, and in the present embodiment, only one end portion is shown and described in FIG.
In each slat 10, a first hook portion 15a facing the outdoor side is formed at the upper end of the fixed wing 15, and a stopper 15b for stopping the opening operation of the movable wing 16 is formed at the base of the first hook portion 15a. ing. A second hook portion 15c is also formed at the lower end portion of the fixed wing 15, and a pressing portion 18 is formed on the second hook portion 15c to press the lower movable wing 16 to open.

On the other hand, the movable wing 16 is provided with a locking portion 20 having a substantially arc-shaped cross section inserted into the first hook portion 15a of the fixed wing 15 at the upper end portion and the first hook portion 15a from the outside to the indoor side. A first engaging portion 21a having a substantially L-shaped cross section that covers the first engaging portion 21a. The first engaging portion 21a is branched from the middle of the first engaging portion 21a and extends upward, at the lower end of the fixed wing 15 of the slat 10 located on the upper side. A second engaging portion 21b that is rotatably inserted into the formed second hook portion 15c is formed. The upper and lower slats 10 are connected by the second hook portion 15c of the upper fixed wing 15 and the second engagement portion 21b of the lower movable wing 16 being rotatably fitted.
Moreover, the movable wing 16 is pressed between the locking portion 20 and the first engaging portion 21a by the pressing portion 18 of the upper fixed wing 15 so that the movable wing 16 is centered on the first hook portion 15a and the second hook portion 15c. A receiving surface 16c that is rotated and opened is formed.

Therefore, in FIGS. 3 and 8, the shutter curtain 12 is slightly moved downward from the closed position where the main body portion 16 a of the movable wing 16 is in contact with the fixed wing 15, and the pressing portion of the upper fixed wing 15 is pressed. By pushing the receiving surface 16c of the lower movable wing 16 at 18, the movable wing 16 rotates and opens in a direction away from the fixed wing 15 as shown in FIG. In this case, the opening operation of the movable wing 16 is stopped when the first engagement portion 21a comes into contact with the stopper 15b of the fixed wing 15, and the movable wing 16 is opened at a predetermined angle, for example, an acute angle with respect to the fixed wing 15. Retained.
In this state, as shown in FIG. 7, the opening 14 of the fixed wing 15 is difficult to visually recognize from the outside, and external light such as sunlight is reflected on the outer surface of the lower movable wing 16 and the inner surface of the movable wing 16 thereon. Then, the light enters from the opening 14 and is collected.

  8A and 8B, the first hook portion 15a formed on the upper end portion of the fixed wing 15 has a shorter length in the width direction at both ends. A first caulking portion 24A is formed by caulking the first engaging portion 21a at the outer end through a notch 23 in which the first engaging portion 21a of the movable wing 16 is notched. Yes. Therefore, the sliding range in the width direction of the movable wing 16 with respect to the fixed wing 15 of each slat 10 is restricted by the first caulking portions 24A at both ends, and the movable wing 16 extends from the fixed wing 15 of the slat 10 in the width direction. It can be prevented from slipping off or coming off.

  Further, the second hook portion 15c at the lower end portion formed on the upper fixed wing 15 has a short length in the width direction at both ends, and the second engaging portion 21b of the movable wing 16 is cut out on the outer side. The second engaging portion 21b at the outer end portion thereof is caulked through the cutout portion 25 to form a second caulking portion 24B. For this reason, the sliding range in the width direction of the lower movable wing 16 with respect to the upper fixed wing 15 is restricted by the second caulking portions 24B at both ends. It is possible to prevent lateral displacement or disengagement in the width direction.

  The first engagement portion 21a and the second engagement portion 21b of the movable wing 16 have the same length as the length between the support portions 16b on both sides, and the first hook portion 15a of the fixed wing 15 is the first engagement portion. The second hook portion 15c has a length to the notches 25 on both sides of the second engagement portion 21b.

Next, the structure of the guide rail portion 7 that guides the vertical movement of the shutter curtain 12 will be described with reference to FIGS. Although the guide rail part 7 is also arrange | positioned at the both sides of the shutter curtain 12, since both are the same structures, it demonstrates with the one guide rail part 7. FIG.
As shown in FIGS. 9, 10, and 11, the pair of guide rail portions 7 fixed to the left and right vertical frames 3 c of the frame 3 has a substantially U-shaped cross section that guides each slat 10 of the shutter curtain 12 so as to be movable up and down. It has the character-shaped receiving part 27 and the attaching part 28 connected with the vertical frame 3c. Through the opening of the receiving portion 27, the end of the fixed wing 15 of each slat 10 and the support portion 16b of the movable wing 16 are inserted into the inside. As shown in FIG. 11, when the slat 10 is in the open state, the horizontal opening width of both ends of the slat 10 and the opening width of the receiving portion 27 are set to be substantially the same.

And the mohair 30 is planted by the base 29 as a fiber body in the inner surfaces 27a and 27b which the receiving part 27 opposes, respectively. The mohair 30 fills the gap between the opening of the receiving portion 27 of the guide rail portion 7 and the shutter curtain 12 and functions as a sound deadening material that guides the vertical movement of the shutter curtain 12.
The mohairs 30 on the inner surfaces 27a and 27b are composed of a plurality of rows of fibers, and the mohairs 30a and 30b provided on the inner and outer inner surfaces 27a and 27b are relatively thick as shown in FIG. It is composed of two types of fibers, a small fiber 31 having a small hardness and a fiber 32 having a relatively large thickness and a large hardness. In addition, about the mohair 30a provided in the inner surface 27a of the room inner side, as shown in FIG.12 (b), you may be comprised with the fiber 31 of the one kind of small hardness mentioned above.

  For example, assuming that the mohairs 30a, 30b on the inner surfaces 27a, 27b extend in three rows in the vertical direction of the guide rail portion 7, the mohairs 30a, 30b on the inner and outer inner surfaces 27a, 27b are shown in FIG. As shown in FIG. 3, the fiber 31 is composed of two rows of soft fibers 31 and one row of fibers 32 having a large thickness and hardness. Alternatively, the mohair 30a on the inner surface 27a on the indoor side is soft with fibers 31, for example, as shown in FIG. 12B, and the mohair 31b on the inner surface 27b on the outdoor side is soft with two rows, as shown in FIG. 12A. Fiber 31 and a hard row of fibers 32.

Therefore, the slat 10 in the closed state fits between the mohairs 30a and 30b provided on the inner surfaces 27a and 27b of the receiving portion 27 of the guide rail portion 7 as shown in FIG. 10 and FIG. Yes.
On the other hand, as shown in FIGS. 11 and 14, in each open slat 10, the narrow support portion 16 b of the movable wing 16 abuts on the mohairs 30 a and 30 b on the inner surfaces 27 a and 27 b on both sides in the receiving portion 27. . In particular, the end of the support portion 16b, which is relatively spaced from the first and second engaging portions 21a, 21b on the outdoor side, comes into contact with the mohair 30b in which a row of fibers 32 having high hardness is mixed, so that the descent due to its own weight Resist and block. Further, even when the slat 10 is to be raised from the outside to the upper side by hand or the like, the mohair 30a, 30b, particularly, the row of fibers 32 having high hardness resists. Furthermore, even in the closed state, each slat 10 does not contact or slightly contacts the mohairs 30a, 30b on both sides, so that the opening / closing operation sound of the shutter curtain 12 can be silenced and held up and down.

  The shutter device 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next. When the shutter curtain 12 closes the opening 2 of the building from the open state to the closed state, the drive motor 9 is driven to rotate in one direction by a switch (not shown), and the shutter curtain 12 is unwound from the state wound up on the shaft 8. As shown in FIG. 3, the movable wing 16 of each slat 10 of the shutter curtain 12 is lowered by being guided by the guide rail portions 7 on both sides in the closed state in which the movable wing 16 abuts against the fixed wing 15.

  Then, the base plate 13 at the lower end of the shutter curtain 12 abuts against the lower frame 3b of the frame 3, and a change in load is detected by a detection means such as an encoder attached to the drive motor 9, or the base plate 13 or It stops when it is detected by a sensor or the like provided on the lower frame 3b or the like. In this state, the opening 2 is closed by the shutter curtain 12.

  In order to open the movable wing 16 for ventilation or lighting from this state, the shutter curtain 12 is further moved slightly downward by the drive motor 9. Accordingly, the movable wing 16 engages the first hook portion 15a by pressing the receiving surface 16c of the movable wing 16 of the lower slat 10 with the pressing portion 18 at the lower end of the fixed wing 15 of each slat 10. By rotating around one engagement portion 21a and the second engagement portion 21b fitted to the second hook portion 15c, the first engagement portion 21a is opened to the outdoor side by a predetermined angle. It stops in the open state in contact with the stopper 15b.

  In this state, as shown in FIG. 7, outdoor wind is sent indoors through the opening 14 of the fixed wing 15, and light such as sunlight is reflected by the lower movable wing 16 and the upper movable wing 16 to be opened. A soft light is irradiated through the room 14. The wind is also distributed softly indoors and outdoors through the opening 14 of the fixed wing 15. Further, since the plurality of openings 14 of the fixed wing 15 are disposed above the lower end of the movable wing 16 in the open state, it is difficult to visually recognize the room through the opening 14 from the outside, and the vertical width of each opening 14 is small. Therefore, privacy can be protected and security safety can be improved.

Further, in order to open the opening 2 of the building, the driving motor 9 is rotated in the reverse direction and the shutter curtain 12 is moved slightly upward so that the pressing portion 18 is separated from the receiving surface 16c of the movable wing 16, and the movable wing 16 is moved to the opening. The opening 14 is closed by contacting the fixed wing 15 with its own weight. Thereafter, the drive motor 9 is further rotated in the reverse direction to wind up the shutter curtain 12 around the shaft 8.
Further, when each slat 10 moves up and down in the closed state, as shown in FIGS. 10 and 13, the fixed wing 15 and the movable wing 16 of each slat 10 receive the guide rail portion 7 at both ends thereof. The inner surface 27a, 27b of the portion 27 moves up and down while being silenced between the mohairs 30a, 30b. Further, even if the movable wing 16 of the slat 10 is artificially opened from the outside, the mohairs 30a and 30b on both inner surfaces 27a and 27b come into contact and resist.

  On the other hand, when the movable wing 16 of the slat 10 is in an open state with respect to the fixed wing 15, the slat 10 has the same width as that between the mohairs 30 a and 30 b of the inner surfaces 27 a and 27 b of the receiving portions 27 of the guide rail portion 7. And abut against each other. Moreover, as shown in FIGS. 11 and 14, the support portions 16 b at both ends of the movable wing 16 are in an open state to abut against the mohair 30 b including the hard fibers 32 on the inner surface 27 b, so that the load in the descending direction due to its own weight can be prevented. And the movable wing 16 is maintained in the open state with the hardness of the mohairs 30a and 30b. Further, when the pressing portion 18 of the fixed wing 15 is separated from the receiving surface 16c of the movable wing 16, the supporting portion 16b is allowed to overcome the resistance of the mohairs 30b and 30a and to be closed by its own weight.

  Moreover, when the opening / closing operation of the shutter curtain 12 and the movable wing 16 in each slat 10 perform the opening / closing operation with respect to the fixed wing 15 provided with the opening 14, each movable wing 16 has a first caulking portion 24A and a second caulking portion. The lateral displacement with respect to the fixed wing 15 can be restricted by 24B.

  As described above, according to the shutter device 1 according to the present embodiment, in each slat 10 of the shutter curtain 12, the movable wing 16 does not laterally shift with respect to the first hook portion 15 a of the fixed wing 15 by the first caulking portion 24 </ b> A. Therefore, it is possible to restrict the movable wing 16 from being laterally displaced from or detached from the fixed wing 15 after assembly. Further, since each movable wing 16 is regulated by the second caulking portion 24B so as not to be laterally displaced with respect to the second hook portion 15c of the upper fixed wing 15, the slat 10 including the movable wing 16 is assembled into the upper slat 10 after assembly. It is possible to regulate the lateral displacement or disengagement from the fixed wing 15.

Further, the first caulking portion 24A provided at both ends of the first engaging portion 21a of the movable wing 16 and the second caulking portion 24B provided at both ends of the second engaging portion 21b are relatively rotated by the notches 23 and 25, respectively. Since it is separated from the inner part that contributes to the movement, even if both ends of the first engaging portion 21a and the second engaging portion 21b are caulked, the rotation of the movable wing 16 relative to the fixed wing 15 is not affected. .
For this reason, the shutter device 1 according to the present embodiment can be easily manufactured by an automatic machine without a separate component attaching step, and the processing cost can be reduced. Moreover, since the first and second caulking portions 24A and 24B are provided on the same surface side of the movable wing 16, the caulking operation is further facilitated.

  Further, mohairs 30a and 30b are provided on the inner surfaces 27a and 27b of the receiving portions 27 of the guide rail portion 7 for inserting the both ends of each slat 10 to guide the vertical movement, and at least the outdoor mohair 30b is hard on the fibers 31. Since the relatively large fibers 32 are mixed, the resistance of the mohair 30b that comes into contact with the support portion 16b when the movable wing 16 is opened is increased so that the support portion 16b can be stably locked and opened. It is possible to keep the mohair 30a, 30b from aging. In addition, when the movable wing 16 is in the closed state, it can be moved up and down stably by moving the slats 10 with the mohairs 30a and 30b.

  Further, in each slat 10, the plurality of openings 14 are arranged so as to be biased to the upper side of the fixed wings 15, so that when the movable wings 16 are opened, it is possible to prevent others from seeing the room from the outside through the openings 14. Therefore, safety, light shielding, and privacy can be ensured, and the lighting through the opening 14 and the adjustment of the amount of wind can be balanced.

  The shutter device 1 according to the present invention is not limited to the above-described embodiment, and can be appropriately changed or replaced without departing from the gist of the present invention. Hereinafter, modifications of the present invention will be described, but the same or similar components or members described in the above-described embodiment will be described using the same reference numerals.

  For example, in the above-described embodiment, the notch portion 23 is formed inside the first caulking portion 24A formed at both ends of the first engagement portion 21a of the movable wing 16, but the notch portion 23 may not be provided. In this case, at least the first engaging portion 21a of the movable wing 16 is not affected on the relative rotation with the first hook portion 15a at a position spaced outside the both ends of the first hook portion 15a of the fixed wing 15. Thus, the first caulking portion 24A may be formed. Similarly, the second engaging portion 21b of the movable wing 16 is not affected on the relative rotation with respect to the second hook portion 15c at positions spaced outward from both ends of the second hook portion 15c of the fixed wing 15. If the second caulking portion 24B is formed, the notch portion 25 may not be provided in the second engaging portion 21b. Thus, the first and second caulking portions 24A and 24B can be formed without adversely affecting the relative rotation of the fixed wing 15 and the movable wing 16.

  In the above-described embodiment, the first caulking portion 24A and the second caulking portion 24B are formed at both ends of the first engaging portion 21a and the second engaging portion 21b of the movable wing 16, respectively. The first hook portion 15a and the second hook portion 15c are not laterally displaced, but instead of this configuration, both ends of the first engaging portion 21a and the second engaging portion 21b of the movable wing 16 are formed short and fixed. The first hook portion 15a and the second hook portion 15c of the wing 15 are formed longer at both ends than the first engagement portion 21a and the second engagement portion 21b, and both ends of the first engagement portion 21a and the second engagement portion 21b. The first caulking portion 24A and the second caulking portion 24B may be formed at both ends on the outer side with the notch portion formed on the outer side or without forming the notch portion, respectively, so that the lateral displacement of the movable wing 16 is prevented. Good.

In addition, as mohair 30a, 30b as a fibrous body, mohair 30a in which fibers 32 having relatively large thickness and fibers 31 having small thickness are mixed on both inner surfaces 27a, 27b of the receiving portion 27 of the guide rail portion 7 facing each other. 30b, but the mohair 30a provided on the inner surface 27a on the indoor side may be configured by arranging only fibers 31 having low hardness along the longitudinal direction.
