Description

  The present invention relates to a shutter that is used in an opening of a building and can be daylighted or ventilated by a slat.

2. Description of the Related Art Conventionally, as a shutter curtain that can perform daylighting and ventilation using a slat as a blind, a shutter curtain provided with an opening for daylighting and ventilation is known. For example, the shutter curtain described in Patent Document 1 is a single shutter curtain in which a closing slat and a ventilation slat that performs ventilation and daylighting are separated and connected in the vertical direction. Both ends of this shutter curtain are located in a guide rail portion having a substantially U-shaped cross section, and the shutter curtain is rolled up or fed out by rotating the shaft in the shutter box provided at the top of the opening of the building forward and backward. Open and close the opening of the building.
Each of the ventilation slats is formed by punching an oval opening in the longitudinal direction. The openings formed in these ventilation slats have good ventilation and lighting, but have a drawback that privacy protection cannot be sufficiently secured because the inside can be visually observed from the outside through the openings.

On the other hand, in the shutter device described in Patent Document 2, a plurality of double slats provided with movable wings that are openable and closable with respect to a fixed wing in which the opening of the through hole is formed in the longitudinal direction are provided in the vertical direction. It is connected. The movable wing can be opened and closed in a closed state in which the shutter curtain closes the opening of the building. In addition, both end portions of the fixed wing and the movable wing are slidably held in the guide rail portion, and the main body portion excluding the both end portions of the movable wing is opened and closed between the guide rails.
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. Daylight and ventilation can be made through the opening. In addition, by setting the angle of the movable wing in the open state with respect to the fixed wing to an acute angle, it is possible to make it difficult to visually recognize the interior from the outside.

  In addition, a central recess is formed in the center of the fixed wing to accommodate the main body of the movable wing. When the movable wing is closed, the movable wing is fixed by fitting the main body of the movable wing into the central recess of the fixed wing. Fits on the outer surface of the wing. In this state, each slat of the shutter curtain is wound up on a shaft in the shutter box, and the shutter curtain is placed in the shutter box.

JP 2011-196082 A European Patent No. 2039871

By the way, in the shutter curtain double slat according to Patent Document 2 described above, the movable wing of each slat has play in the lateral direction with respect to the fixed wing in consideration of its manufacturing error, mounting error to the fixed wing, etc. When the movable wing is attached, it may be displaced laterally with respect to the fixed wing. In addition, when a person or object hits the movable wing in the open state, the movable wing may be displaced laterally with respect to the fixed wing.
If the movable wing of the shutter wing is closed when the movable wing is laterally displaced, the body of the movable wing that is laterally displaced will not fit in the central recess of the fixed wing, and the main body of the movable wing will be one of the two ends of the central recess of the fixed wing. There was a risk of getting on top.

  In this case, since the movable wings of the slats are displaced laterally with respect to the fixed wings and a gap is generated, indoor or outdoor light may leak from the gap. In addition, when the shutter curtain is rolled up on the shaft, if some movable slat wings ride on the fixed blade, they cannot be rolled up concentrically and do not fit in the shutter box or get caught when the shutter curtain is extended. There was also a risk of hindrance.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a shutter capable of adjusting the lateral displacement of the movable wing with respect to the fixed wing of each slat of the shutter curtain.

The shutter according to the present invention is a shutter in which a plurality of slats each having a fixed wing provided with an opening and a movable wing capable of opening and closing the opening are connected in the vertical direction. The movable wing opens and closes the opening of the fixed wing. A main body portion is formed, and a recessed portion for housing the main body portion of the movable wing is formed in the fixed wing, and a first contact portion provided at a side edge portion of the main body portion of the movable wing and a side edge portion of the concave portion of the fixed wing A tapered portion is formed on at least one of the provided second contact portions.
According to the present invention, when the movable wing in the open state is displaced laterally with respect to the fixed wing, the movable wing does not fit in the recessed portion of the fixed wing even if the movable wing is closed, but the first of the movable wings When the abutting portion and the second abutting portion of the fixed wing come into contact with each other, at least one of the abutting portions is a tapered portion, so that the other abutting portion is moved sideways along the tapered portion by the closing operation of the movable wing. By adjusting the position deviation, the main body can be accommodated in the recessed portion of the fixed wing.

In addition, the first contact portion provided at the left and right side edge portions of the main body portion that opens and closes the opening of the movable wing and the second contact portion provided at the left and right side edge portions of the concave portion having the opening of the fixing portion are respectively It is preferable that it is a taper part.
When the movable wing is closed and moved sideways, the taper on one of the side edges is pressed against the taper on the one side edge of the fixed wing, and the movable wing moves sideways to move the body. Therefore, the main body of the movable wing can be reliably fitted into the recessed portion of the fixed wing.

Moreover, it is preferable that a 1st contact part and a 2nd contact part are resin.
Even if the movable wing and the fixed wing are made of a metal such as an aluminum alloy, if the first abutting portion and the second abutting portion are made of resin, the movable wing is slid by the taper portion because it is flexible. Thus, the main body can be fitted into the recess by adjusting the positional deviation. And since the 1st and 2nd contact part is resin, it does not make a sound at the time of a collision, and it is not damaged.

  According to the shutter of the present invention, at least one of the first contact portion provided at the side edge portion of the main body portion of the movable wing and the second contact portion provided at the side edge portion of the recessed portion of the fixed wing is a tapered portion. Therefore, when the movable wing is closed, the taper portion, which is one of the contact portions, and the other contact portion come into contact with each other to adjust the positional deviation of the movable wing and can be accommodated in the recess. Therefore, even if the movable wing is displaced laterally, the movable wing of the closed slat does not ride on the fixed wing, and the main body can be securely fitted into the recessed portion of the fixed wing by the lateral movement of the movable wing. Since there is no gap between the movable wing and the fixed wing in the closed state, light does not leak, and the shutter curtain can be rolled up and fed out with high accuracy.

Hereinafter, a shutter according to an embodiment of the present invention will be described with reference to FIGS.
The shutter 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 is formed in a rectangular frame shape with an upper frame, a lower frame, and a pair of left and right vertical frames. . A shutter box 4 is installed between the top plate on the upper side of the frame 3 and the upper frame. A pair of guide rail portions 5 are attached to the vertical frames on both sides below the shutter box 4 in the vertical direction.

A shaft 7 connected to a drive motor is installed inside the shutter box 4, and a shutter curtain 10 having a plurality of long slats 9 connected in the vertical direction is wound around the shaft 7. When the shutter curtain 10 is rolled up by forward / reverse rotation of the drive motor, the opening state of the opening 2 can be obtained, and when the shutter curtain 10 is extended and lowered to the lower end, the opening 2 can be closed.
The vertical movement of the shutter curtain 10 is guided by the guide rail portion 5 that sandwiches both end portions thereof. For example, a sliding shoji 6 is installed as a window inside the opening 2 of the frame 3 that opens and closes the shutter curtain 10.

Next, the structure of the shutter curtain 10 will be described with reference to FIGS. In FIG. 2, the shutter curtain 10 has a plurality of double slats 9 vertically connected to the upper side of the baseboard 12 provided at the lower end thereof.
As shown in FIGS. 3 to 6, each slat 9 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 portion and the upper end portion of the movable wing 16 of the lower slat 9 are rotatably connected to each other in the vertical direction. Each 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 are made of a lightweight metal such as an aluminum alloy. 3 and 4, only one end of the fixed wing 15 and the movable wing 16 is shown, but the other end also has a symmetrical shape.

  The fixed wing 15 and the movable wing 16 in each slat 9 have a substantially long plate shape that is long in the lateral direction, and are formed, for example, curved outward in a circular arc shape in a longitudinal sectional view. As shown in FIGS. 5 and 6, the fixed wing 15 is fixed to both sides of the central concave portion 20 (concave portion) in which the convex portion 17 formed on the surface on the outdoor side is formed in a band shape in the lateral direction. Both fixed end portions 21 are provided. Moreover, a plurality of convex portions 17 are formed in the vertical direction at a predetermined interval.

Further, in the central recess 20 shown in FIG. 6, an oval opening 14 divided into one or a plurality of strips is formed in the horizontal direction in a thin portion between the projections 17 adjacent in the vertical direction. In the present embodiment, a plurality of openings 14 are arranged between the convex portions 17 in the vertical direction. The opening 14 of the fixed wing 15 is formed by punching from the indoor side (concave surface side) to the outdoor side (convex surface side) using a mold, for example. A net for insect repellent may be attached to each opening 14.
In the fixed wing 15, the fixed end portions 21 provided at both side edges of the central recess 20 are made of resin and project outward from the central recess 20. A tapered portion 22 forming an inclined surface is formed at the boundary between each fixed end portion 21 and the central recess 20.

In the example shown in the present embodiment, as shown in FIG. 5, a plurality of openings 14 and protrusions 17 are arranged at equal intervals in the longitudinal width direction of the fixed wing 15, but the openings 14 and protrusions 17 are fixed wings. 15 may be formed so as to be biased toward the upper side in the vertical direction. When the openings 14 are installed at equal intervals in the vertical direction of the fixed wing 15, indoor and outdoor winds are good with the movable wings 16 open, and lighting can be obtained almost evenly.
On the other hand, if the openings 14 are arranged so as to be biased to the upper side of the fixed wings 15, it is difficult to visually recognize the inside of the openings 14 from the outside even when the movable wings 16 are open. The external light is reflected from the outer surface of the lower movable wing 16 and the inner surface of the upper movable wing 16 and is incident from the opening 14 so that soft light can be collected. The wind can also be circulated indoors and outdoors through a plurality of openings 14 from the gap between the movable wing 16 and the fixed wing 15 in the open state.

3 and 4, the movable wing 16 is formed in the central region, has a length in the vertical width direction that is substantially the same as the fixed wing 15, and can open and close the opening 14 of the fixed wing 15. The both end portions are notched to form a support portion 16b having a small length in the vertical direction. The main body portion 16 a is fitted in the central recess 20 having the opening 14 of the fixed wing 15 in the closed state of the slat 9, and is flush with both fixed end portions 21 of the fixed wing 15.
As shown in FIGS. 3, 4, 7, and 8, a movable end portion 23 made of resin is fixed to both side edges of the main body portion 16 a, and the movable end portion 23 contacts the tapered portion 22 of the fixed blade 15. The taper part 24 which touches is formed.
The both fixed end portions 21 of the fixed wing 15 and the support portions 16b of the movable wing 16 are partially inserted into the guide rail portions 5 on both sides to be guided in the vertical movement, and the main body portion 16a of the movable wing 16 is It is located between the guide rail portions 5 on both sides and opens outward.

As shown in FIG. 6, ribs 26 a and 26 b having substantially L-shaped cross sections are formed on the indoor side surface of the main body portion 16 a of the movable wing 16 so as to protrude from the upper side and the lower side. Also, a rib 17a and a stopper 17b having a substantially L-shaped cross section are formed above and below the opening 14 on the surface on the movable wing 16 side. Therefore, when the movable wing 16 is rotated from the open state shown in FIG. 6B to the closed state shown in FIG. 6A, the ribs 26a and 26b of the movable wing 16 and the ribs 17a of the fixed wing 15 and the stopper are stopped. 17b contacts the fixed wing 15 and the movable wing 16, respectively, so that the main body portion 16a of the movable wing 16 is fitted and closed in the central recess 20 of the fixed wing 15 so that a space k having a predetermined width is formed between the fixed wing 15 and the fixed wing 15. Form.
The ribs 17a, 26a, 26b and the stopper 17b prevent the movable wing 16 from opening even if foreign matter such as insects or dust is sandwiched between the movable wing 16 in the closed state and the fixed wing 15. In addition, when the shutter curtain 10 is wound around the shaft 7, the winding failure due to the foreign matter does not occur, and the space k of the slat 9 is prevented from being crushed by the weight of the other wound slat 9.

Next, the connection structure of the plurality of slats 9 will be described with reference to FIG. Although only two slats 9 are shown in FIG. 6, three or more are connected in this embodiment.
In each slat 9, a first hook portion 15a facing the outdoor side is formed at the upper end portion 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 28 is formed on the second hook portion 15c for pressing the lower movable wing 16 to open it.

On the other hand, the movable wing 16 has a locking portion 29 that is rotatably inserted into the first hook portion 15a of the fixed wing 15 at the upper end, and a substantially L-shaped cross section that covers the first hook portion 15a from the outside to the indoor side. A first engaging portion 30a in the form of a ring, further branching from the middle of the first engaging portion 30a and extending upward, and is turned into the second hook portion 15c of the fixed wing 15 of the slat 9 located on the upper side. A second engagement portion 30b that is movably inserted is formed. The upper and lower slats 9 are connected by the second hook portion 15c of the upper fixed wing 15 and the second engagement portion 30b of the lower movable wing 16 being rotatably fitted.
In addition, the movable wing 16 is pressed between the locking portion 29 of the movable wing 16 and the first engagement portion 30a by the pressing portion 28 of the upper fixed wing 15 so that the movable wing 16 is moved to the first hook portion 15a and the second hook portion. A receiving surface 16c is formed that is pivoted about 15c to open.

Therefore, in FIG. 6A, the shutter curtain 10 is moved slightly downward from the closed position where the main body portion 16a of the movable wing 16 is in contact with the stopper 17b of the fixed wing 15, and the upper fixed wing 15 is moved upward. By pressing the receiving surface 16c of the lower movable wing 16 with the pressing portion 28, the movable wing 16 rotates and opens in a direction away from the fixed wing 15 as shown in FIG. 6B. become. In this case, in FIG. 6B, the opening operation of the movable wing 16 stops when the first engagement portion 30 a abuts against the stopper 15 b of the fixed wing 15, and the movable wing 16 has a predetermined angle with respect to the fixed wing 15. For example, it is held open at an acute angle.
In this state, 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 on the lower surface and enters from the opening 14. And daylight.

The shutter 1 according to the present embodiment has the above-described configuration. Next, a method for using the shutter curtain 10 will be described.
When the opening 2 of the building is closed from the open state to the closed state by the shutter curtain 10, as shown in FIG. 2, the drive motor is driven to rotate and the shutter curtain 10 is unwound from the state wound up on the shaft 7. Each slat 9 is lowered by being guided by the guide rail portions 5 on both sides in a closed state in which the movable wing 16 is in contact with the fixed wing 15.

  Then, as shown in FIG. 2, the baseboard 12 at the lower end of the shutter curtain 10 comes into contact with the lower frame of the frame 3 and stops when it detects that the load has changed. In this state, the opening 2 is closed by the shutter curtain 10. From this state, in order to open the movable wing 16 for ventilation or lighting, the shutter curtain 10 is further moved slightly downward by a drive motor.

  As a result, as shown in FIG. 6 (b), the movable wing 16 is moved by pressing the receiving surface 16 c of the movable wing 16 of the lower slat 9 with the pressing portion 28 at the lower end of the fixed wing 15 of each slat 9. By rotating around the first engagement portion 30a that fits the first hook portion 15a and the second engagement portion 30b that fits the second hook portion 15c, it opens to the outdoor side by a predetermined angle, The first engaging portion 30a comes into contact with the stopper 15b of the fixed wing 15 and stops in the open state. At that time, since the main body portion 16a of the movable wing 16 is located between the opposing guide rail portions 5, the opening operation is smoothly performed.

  In this state, as shown in FIG. 6B, light such as sunlight is reflected by the lower movable wing 16 and further reflected by the inner surface of the upper movable wing 16 to irradiate the interior through the opening 14. The wind is also distributed softly indoors and outdoors through the opening 14 of the fixed wing 15. In addition, since the plurality of openings 14 of the fixed wing 15 are disposed on the indoor side of the movable wing 16 in the open state, it is difficult to visually recognize the room from the outside through the opening 14, and privacy is protected and safety for crime prevention. Can be improved.

  When the movable wing 16 is in an open state, a person or an object may come into contact with the movable wing 16 to move slightly to the fixed wing 15 of the slat 9. When the movable wing 16 is closed in this state, first, the drive motor is reversely rotated to move the shutter curtain 10 slightly upward, so that the pressing portion 28 is separated from the receiving surface 16c of the movable wing 16, and the movable wing 16 is moved to the movable wing 16. It is closed by its own weight.

At this time, as shown in FIG. 7, the tapered portions 24 provided at both movable end portions 23 of the main body portion 16 a of the movable wing 16 are separated from the tapered portions 22 provided at both fixed end portions 21 of the central recess 20 of the fixed wing 15. It's off. In FIGS. 7B and 7C, the one laterally offset taper portion 24 of the movable wing 16 abuts on the upper end portion of the one taper portion 22 of the fixed wing 15, and the other taper portion 24 is the other taper portion 22. Get away from. Then, due to the closing operation force of the movable wing 16, the one taper portion 24 comes into contact with and pushes against the one taper portion 22, which is opposed, and moves laterally by a small amount.
Then, the first engaging portion 30 a and the second engaging portion 30 b of the movable wing 16 are guided by the first hook portion 15 a of the fixed wing 15 and slide a minute amount. The position is adjusted to a position where the tapered portions 24 and 22 on both sides face each other by returning to the correct position facing the central recess 20. Then, the taper portions 24 on both sides of the movable wing 16 correctly contact the tapered portions 22 on both sides of the fixed wing 15, and the movable wing 16 does not run on the fixed wing 15, so that the main body portion 16 a of the movable wing 16 Fits into the central recess 20.
And in order to open the opening part 2 of a building, what is necessary is just to wind up the shutter curtain 10 to the shaft 7 by reversely rotating a drive motor.

As described above, according to the shutter 1 according to the present embodiment, in each slat 9 of the shutter curtain 10, even if the movable wing 16 of each slat 9 is shifted laterally with respect to the fixed wing 15 in the open state, When the closing operation is performed, the tapered portion 24 abuts against the tapered portion 22 of the fixed wing 15 and slides to adjust the position, so that the main body portion 16a of the movable wing 16 is securely fitted in the central recess 20 of the fixed wing 15. Can be closed together.
Therefore, no light leaks from the gap between the main body portion 16a and the central recess 20 of the fixed wing 15 when the movable wing 16 is closed, and the winding and unwinding by the shaft 7 of the shutter curtain 10 is hindered due to the displacement. It can be done accurately without coming.
Moreover, since the movable end 23 having the taper portion 24 of the movable wing 16 and the fixed end portion 21 having the taper portion 22 of the fixed wing 15 are made of resin and flexible, the taper is applied when the movable wing 16 is closed. Even if the parts 24 and 22 come into contact with each other, it is possible to prevent abnormal noise from being generated or damaged.

  The shutter 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 movable end portion 23 of the main body portion 16a of the movable wing 16 and the fixed end portion 21 of the fixed wing 15 are tapered to each other, but at least one of them may be tapered. In this case, the other may be a corner or the like. The tapered portion 24 of the movable wing 16 is referred to as a first contact portion, and the tapered portion 22 of the fixed wing 15 is referred to as a second contact portion.
