Hereinafter, a roll screen which is an embodiment of a shielding device will be described with reference to the drawings.
[First Embodiment]
As an example, this roll screen is used as a partition that partitions a room and a staircase. As shown in FIG.1 and FIG.2, the roll screen 10 is attached to the installation part 2 provided in the opening used as the entrance of stairs seeing from a room. Here, the front surface of the roll screen 10 faces the room side, and the rear surface faces the staircase side. The installation unit 2 is at least a ceiling or an upper frame provided on the ceiling. The roll screen 10 includes a head unit 11 attached to the installation unit 2 and a screen 12 suspended from the head unit 11. The screen 12 functions as a shielding member in the present disclosure. The head unit 11 is attached to the installation unit 2 via the bracket 4. The head portion 11 includes side covers 11b at both ends in the width direction. The side cover 11b rotatably supports a winding pipe 11a as a winding shaft for winding the screen 12 therein. As shown in FIG. 3, the winding pipe 11 a extends in the width direction of the head portion 11 and includes a sprocket 13 at one end in the width direction. An annular operation chain 14 that rotates the take-up pipe 11a is engaged with the sprocket 13 as an operation portion. The operation chain 14 is suspended from one end portion in the width direction of the head portion 11, and two chains constituting the operation chain 14 are suspended. The operation chain 14 rotates the winding pipe 11a in the drawing direction of the screen 12 or rotates it in the winding direction of the screen 12 by performing an operation of pulling down one of the two chains. Thereby, the screen 12 is moved up and down together with the weight bar 15.

  As an example, the screen 12 is coated with a flexible resin material such as polyvinyl chloride to improve the durability of a flexible sheet such as a belt-shaped cloth as a whole. The upper end portion of the screen 12 is fixed to the take-up pipe 11a, and the lower end portion is attached with a weight bar 15 that stabilizes the position of the screen 12 in the vertical direction. In the screen 12, the vertical edge portion extending in the vertical direction between the upper edge portion and the lower end portion is an end portion 12 a (see FIG. 1) extending in the vertical direction between the screen 12 and the weight bar 15. The head unit 11 includes a shield 16 that closes a gap generated around the winding pipe 11a. As an example, the shield 16 is suspended from the upper part toward the lower part on the front surface of the head part 11 on the room side. Since the diameter of the winding portion where the screen is wound around the winding pipe 11a changes according to the winding amount of the wound screen 12, the size of the gap around the winding portion when viewed from the front or the back surface. Changes. When the weight bar 15 is lowered, the gap around the take-up pipe 11a becomes larger because the take-up portion has a small diameter. The shield 16 closes such a gap regardless of the winding amount of the screen 12 in the winding pipe 11a, makes it difficult for air to flow between the room and the stairs, and improves the light shielding property.

  The weight bar 15 includes a magnet 17 as a holding portion (see FIG. 1). Further, the magnetic body 6 is disposed at a position where the weight bar 15 of the floor 5 faces. As an example, the magnet 17 is a magnet sheet disposed at the lowermost end along the width direction. When the magnet 17 is lowered to the lower limit position, the magnet 17 is brought into close contact with the magnetic body 6 of the floor 5 by a magnetic attractive force. This makes it difficult to form a gap between the weight bar 15 and the floor 5 at the lower limit position.

  The roll screen 10 having the basic configuration as described above includes a closing mechanism 20 for closing a gap between the vertical frame 3 and the end 12 a of the screen 12. As shown in FIG. 4, the closing mechanism 20 is provided in the vertical frame 3 on both sides in the width direction. Each closing mechanism 20 is fixed to the surface of the vertical frame 3 and the base plate 21. A first side plate 22 and a second side plate 23 that are rotatable and extend in the vertical direction are provided. As an example, the base plate 21 extends from the floor 5 to the winding pipe 11a. As an example, the upper ends of the first side plate 22 and the second side plate 23 are maximum when the weight bar 15 is at the upper limit position and the winding portion where the screen 12 is wound around the winding pipe 11a has the maximum outer diameter. The position is slightly below the outer diameter winding portion, that is, as high as possible without interference. Moreover, a lower end is a position which adjoins the floor 5 as an example.

  As shown in FIG. 5A, the base plate 21 is a fixed plate that is fixed to the vertical frame 3 by screws 24a. Specifically, the base plate 21 is a plate that rotatably supports two side plates arranged side by side in the front-rear direction. The screws 24 a are inserted into the mounting holes 24 and fastened to the vertical frame 3, whereby the base plate 21 is integrated with the vertical frame 3. A first side plate 22 and a second side plate 23 are rotatably attached to the base plate 21 so as to extend in the vertical direction at a central position in the front-rear direction. The base plate 21 has a first rotation support portion 25 and a second rotation support portion 26 so that the first side plate 22 and the second side plate 23 extend in the vertical direction in parallel at the center position in the front-rear direction. It has. The 1st rotation support part 25 is a cylindrical part which comprises the shaft hole by which the 1st rotation shaft 25a (refer FIG. 4) is penetrated, and the 2nd rotation support part 26 is the 2nd rotation shaft 26a. It is a cylindrical part which comprises the axial hole in which (refer FIG. 4) is penetrated. A first rotating portion 28 of the first side plate 22 and a second rotating portion 29 of the second side plate 23 are arranged on both sides of the first rotating support portion 25 and the second rotating support portion 26 in the vertical direction. This is a support recess 27.

  As shown in FIG. 5B, the first side plate 22 and the second side plate 23 are movable plates that block the gap between the end portion 12 a and the base plate 21 in a portion overlapping the end portion 12 a of the screen 12. For example, the first side plate 22 is positioned in a space on the room side with respect to the screen 12, and the second side plate 23 is positioned in a space on the staircase side with respect to the screen 12 as an example. The first side plate 22 and the second side plate 23 are plates having an elongated rectangular shape, and the first side plate 22 has a first rotating portion 28 disposed in the support recess 27 on one long side. The second side plate 23 includes a second rotating portion 29 disposed in the support recess 27 on one long side.

  The first rotating portion 28 and the second rotating portion 29 are shaft insertion portions configured by a cylindrical portion constituting the shaft hole, and the first rotating portion 28 is connected to the first rotating support portion 25. The axes are matched and the first rotation shaft 25a is inserted. Further, the second rotating portion 29 has the same axis as the second rotating support portion 26, and the second rotating shaft 26a is inserted therethrough. The first side plate 22 is between an open position that is substantially parallel to the base plate 21 and a closed position that is substantially perpendicular to the base plate 21, that is, a range of approximately 90 ° is centered on the first rotation shaft 25a. Rotate. The second side plate 23 also has a range of approximately 90 ° between the open position that is substantially parallel to the base plate 21 and the closed position that is substantially perpendicular to the base plate 21, that is, the second rotation axis 26a as a center. Rotate.

  The rotation center of the first side plate 22 is between the screen 12 hanging from the head portion 11 and the rotation center 11c (see FIG. 3) of the winding pipe 11a in the front-rear direction, that is, the screen 12 and the winding pipe 11a. And a virtual vertical plane that hangs down from the rotation center 11c. That is, the first side plate 22 is located between the screen 12 and the rotation center 11c of the winding pipe 11a when in the closed position that is substantially perpendicular to the base plate 21. The rotation center of the second side plate 23 is parallel to the first side plate 22 and is located outside the screen 12 with respect to the first side plate 22. When the first side plate 22 and the second side plate 23 arranged in this manner are in a closed position that is substantially perpendicular to the base plate 21, the end 12a of the screen 12 is sandwiched therebetween. In the open position that is substantially parallel to the base plate 21, the first side plate 22 and the second side plate 23 face each other, that is, the first rotation unit 28 and the second rotation unit 29. The opposite free ends are positioned so as to be separated from each other (facing the opposite side).

  The 1st rotation part 28 is provided with the 1st gear part 28a in the circumference, the 2nd rotation part 29 is provided with the 2nd gear part 29a in the circumference, and the 1st gear part 28a, the 2nd gear part 29a, Are meshing with each other. Thereby, the 1st side plate 22 and the 2nd side plate 23 interlock | cooperate. Therefore, when the first side plate 22 is in the closed position, the second side plate 23 is also in the closed position, and when the first side plate 22 is in the open position, the second side plate 23 is also in the open position. The first side plate 22 and the second side plate 23 are set such that the distance between the tip portions when they are in the closed position is shorter than the length in the width direction of the weight bar 15. Thereby, even when the 1st side plate 22 and the 2nd side plate 23 are a closed position, the screen 12 and the weight bar 15 are comprised so that raising / lowering is possible.

  In assembling each closing mechanism 20 configured as described above, first, the base plate 21 is fixed to the vertical frame 3 with screws 24a. Next, the first turning portion 28 of the first side plate 22 and the second turning portion 29 of the second side plate 23 are combined with the support recess 27 of the base plate 21. Then, the first rotation shaft 25 a is inserted through the first rotation support portion 25 and the first rotation portion 28. Further, the second rotation shaft 26 a is inserted through the second rotation support portion 26 and the second rotation portion 29. At this time, the first gear portion 28a of the first rotating portion 28 and the second gear portion 29a of the second rotating portion 29 mesh with each other. As a result, the first side plate 22 and the second side plate 23 can rotate in conjunction with the base plate 21.

Next, the operation of the roll screen 10 configured as described above will be described.
As shown in FIG. 6A, the roll screen 10 is moved up and down by operating the operation chain 14 when the first side plate 22 and the second side plate 23 are in the open position. Since the first side plate 22 and the second side plate 23 are in the open position, both end portions of the weight bar 15 are smoothly raised and lowered without contacting the first side plate 22 and the second side plate 23, and the screen 12 Can be raised and lowered smoothly. The opening at the boundary between the room where the roll screen 10 is installed and the stairs is not narrowed and difficult to pass because the first side plate 22 and the second side plate 23 are in the open position.

  When the room and the stairs are partitioned, first, the operation chain 14 is operated, the weight bar 15 is lowered to the lower limit position, and the two spaces are partitioned by the screen 12. In this state, the weight bar 15 is magnetically attracted to the floor 5, thereby suppressing the formation of a gap between the weight bar 15 and the floor 5.

  As shown in FIG. 6B, when the weight bar 15 is in the lower limit position, one of the first side plate 22 and the second side plate 23 in the open position is closed from the open position to the closed position. It is rotated in the direction. Then, the other side plate also interlocks and rotates in the closing direction from the open position to the closed position. Thereby, the end 12a of the screen 12 is sandwiched between the first side plate 22 and the second side plate 23, and the gap between the end 12a and the base plate 21 is closed. Here, when the weight bar 15 is lowered, a gap around the take-up pipe 11 a becomes large, but this gap is closed by the shield 16.

  When the first side plate 22 and the second side plate 23 are in the closed position, as an example, the relationship between the end 12a and the first side plate 22 and the second side plate 23 impairs the convenience of raising and lowering the screen 12. In order to prevent the screen 12 from being touched lightly, the screen 12 is not so hindered from raising and lowering. In such a case, even if the screen 12 comes into contact with the first side plate 22 and the second side plate 23 and the operation force of the operation chain 14 that moves up and down the screen 12 and the weight bar 15 may become slightly heavy, the screen 12 The weight bar 15 can be raised and lowered.

  Further, as an example, regarding the relationship between the end portion 12 a and the first side plate 22 and the second side plate 23, the end portion 12 a is sandwiched between the first side plate 22 and the second side plate 23. In this case, the first side plate 22 and the second side plate 23 sandwich the end portion 12a with a clamping force that causes the screen 12 and the weight bar 15 to hinder the lifting and lowering. As a result, when the first side plate 22 and the second side plate 23 are in the closed position, the screen 12 and the weight bar 15 are difficult to move up and down, but the end 12a, the first side plate 22 and the second side plate 23 It becomes difficult to form a gap between them, and it becomes difficult for air to escape.

  When the weight bar 15 is raised in the direction of the upper limit position, the operation chain 14 is operated after the first side plate 22 and the second side plate 23 are rotated from the closed position to the open position in the open direction. .

The roll screen 10 as described above can obtain the effects listed below.
(1-1) In a state where the weight bar 15 is lowered to the lower limit position, the end portion 12a of the screen 12 is sandwiched between the first side plate 22 and the second side plate 23, whereby the end portion 12a and the base plate 21 are It is possible to prevent a gap between the two. Thereby, the flow of air between the space of the room and the space of the stairs is blocked, and the airtightness can be improved. Even if the screen 12 is pushed from one space by a difference in wind or atmospheric pressure or by a hand, the end 12a is sandwiched between the first side plate 22 and the second side plate 23, so that the gap Is difficult to form.

  (1-2) Since the first side plate 22 and the second side plate 23 rotate in conjunction with each other, the other side plate can also be rotated by rotating any one of the side plates. . That is, when the weight bar 15 is at the lower limit position, even if the space is partitioned by the screen 12, the second side plate 23 can be moved only by rotating the first side plate 22 from the room side. The first side plate 22 can be rotated only by rotating the second side plate 23 from the staircase side. Thereby, the operativity can be improved.

  (1-3) In the state where the weight bar 15 is at the lower limit position, the weight bar 15 is magnetically attracted to the floor 5, thereby suppressing the formation of a gap between the weight bar 15 and the floor 5. Therefore, it becomes difficult for air to flow between the space of the room and the space of the stairs.

  (1-4) The first side plate 22 is located between the screen 12 and the rotation center 11c of the winding pipe 11a. The upper end of the first side plate 22 is, for example, a position close to the winding portion when the winding portion around which the screen 12 is wound around the winding pipe 11a has the maximum diameter (when the weight bar 15 is at the upper limit position). Become. Therefore, even if the weight bar 15 is at the lower limit position and the gap between the winding portion and the upper end portion of the first side plate 22 is increased, the gap can be reduced as much as possible. The air can be made difficult to flow between.

  (1-5) In the head portion 11, the gap around the winding pipe 11 a can be closed by the shield 16 including the gap (1-4). Thereby, regardless of the diameter of the winding unit, the gap around the winding unit can be closed, and air hardly flows between the space of the room and the space of the staircase.

[Second Embodiment]
The roll screen 40 of the second embodiment shown in FIG. 7 includes a front operation unit 41 and a rear operation unit 46. The winding pipe of the screen 12 is provided with a driving gear 42 coaxial with the winding pipe and the rotating shaft at one end in the width direction. The front operation unit 41 includes a front substrate 41a extending from the head unit 11 to the room side. A front pulley gear 43 and a front intermediate gear 44 are pivotally supported by the front substrate 41a with respect to the drive gear 42. A front pulley gear 43 is connected to the drive gear 42 via a front intermediate gear 44. The operation chain 14 is engaged with the front pulley gear 43.

  The rear operation unit 46 includes a rear substrate 46 a extending from the head unit 11 to the staircase side. A rear pulley gear 47 and a rear intermediate gear 48 are pivotally supported by the rear substrate 46 a with respect to the drive gear 42. A rear pulley gear 47 is connected to the drive gear 42 via a rear intermediate gear 48. The operation chain 14 is engaged with the rear pulley gear 47.

The roll screen 40 as described above can obtain the effects listed below.
(2-1) When the operator is on the room side with respect to the screen 12, the weight bar 15 can be moved up and down using the front operation unit 41. Further, when the weight bar 15 is at the lower limit position, the first side plate 22 is rotated to rotate the first side plate 22 and the second side plate 23 from the open position to the closed position, or from the closed position. It can be rotated to the open position.

  Further, when the operator is on the stairs side with respect to the screen 12, the lifting operation of the weight bar 15 can be performed using the rear operation unit 46. Further, when the weight bar 15 is in the lower limit position, the second side plate 23 is rotated to rotate the first side plate 22 and the second side plate 23 from the open position to the closed position, or from the closed position. It can be rotated to the open position.

[Third Embodiment]
The roll screen 50 of the third embodiment omits the second side plate 23 as a support means for supporting the end portion 12 a of the screen 12, and instead magnetically attracts the end portion 12 a with respect to the first side plate 22. It is a configuration. As shown in FIG. 8, a magnet sheet 51 as a magnet is attached to the first side plate 22. The first side plate 22 is not provided with the first gear portion 28a. On the other hand, a magnetic sheet 52 is attached to the end 12 a of the screen 12. The magnetic sheet 52 may be a soft magnetic sheet or a magnet sheet.

  9, the rotation center of the first side plate 22 is between the screen 12 and the rotation center 11c of the winding pipe 11a in the front-rear direction, that is, the rotation center 11c of the screen 12 and the winding pipe 11a. It is located between the virtual vertical plane that hangs down from. Further, the first side plate 22 is located closer to the room than the screen 12. Thus, it is preferable that the position of the 1st side plate 22 is a position of the grade which contacts the edge part 12a of the screen 12 suspended from the head part 11, when it is a closed position. This is because the gap between the end portion 12a and the first side plate 22 is also reduced, and is easily attracted magnetically.

  Even in the roll screen 50 as described above, the first side plate 22 is rotated from the open position to the closed position when the weight bar 15 is lowered and partitioned by the screen 12. In the position where the weight bar 15 is lifted, the first side plate 22 is kept in the open position, so that the opening at the boundary between the room where the roll screen 50 is installed and the stairs is not narrow and is easy to pass. Maintained. The lifting and lowering of the weight bar 15 is preferably performed when the first side plate 22 is in the open position, but can be performed even in the closed position.

The roll screen 50 as described above can obtain the effects listed below.
(3-1) When the weight bar 15 is at the lower limit position, the end 12a of the screen 12 is magnetically attracted by the magnet sheet 51 of the first side plate 22 to the first side plate 22 Supported by Even with such a configuration, the gap between the base plate 21 and the end 12a of the screen 12 can be closed.

  (3-2) Even in such a roll screen 50, the lifting and lowering of the weight bar 15 is performed when the first side plate 22 is in the open position. As a result, the magnetic sheet 52 at the end 12 a is magnetically attracted to the magnet sheet 51 of the first side plate 22, and the weight bar 15 can be prevented from moving up and down.

  (3-3) As shown in FIG. 9, the first side plate 22 is located between the screen 12 and a virtual vertical plane that hangs down from the rotation axis of the winding pipe 11 a. That is, the first side plate 22 is located closer to the room than the screen 12. Accordingly, when viewed from the staircase side, the first side plate 22 is hidden by the end 12a of the screen 12, and the appearance is improved. When viewed from the room side, it can be visually recognized that the first side plate 22 is in the closed position, and it can be visually confirmed that the gap between the screen 12 and the base plate 21 is closed. Further, the first side plate 22 can be easily turned from the room side.

  (3-4) The upper end of the first side plate 22 is, for example, when the winding portion around which the screen 12 is wound around the winding pipe 11a has the maximum diameter (when the weight bar 15 is at the upper limit position), the winding portion It becomes a position close to. Therefore, even if the weight bar 15 is at the lower limit position and the gap between the winding portion and the upper end portion of the first side plate 22 is increased, the gap can be reduced as much as possible. Further, the gap between the winding portion and the upper end portion of the first side plate 22 is made as small as possible when the first side plate 22 is disposed on the opposite side (step side) to the winding pipe 11a with respect to the screen 12. can do. Further, when the first side plate 22 is disposed on the opposite side (room side) to the screen 12 suspended from the winding pipe 11a, the winding portion and the upper end portion of the first side plate 22 are arranged. The gap can be reduced.

(3-5) A gap between the winding unit and the upper end of the first side plate 22 can be closed by the shield 16.
(3-6) Since the base plate 21 only needs to support the first side plate 22 so as to be rotatable, the base plate 21 has a narrower width in the front-rear direction than the case where the two side plates are rotatably supported. It can be downsized.

[Fourth Embodiment]
As shown in FIG. 10, in the roll screen 60 of the fourth embodiment, a magnet sheet 61 as a magnet is attached to the first side plate 22. On the other hand, a metal staple 62 as a magnetic body is locked to the end 12 a of the screen 12.

The roll screen 60 as described above can obtain the effects listed below.
(4-1) The end portion 12a of the screen 12 is merely provided with the staple 62 instead of the magnetic sheet 52. Therefore, when the screen 12 is wound around the winding pipe, both end portions in the width direction can be prevented from becoming larger in diameter than the central portion, and winding deviation can be prevented.

In addition, the above roll screens can also be implemented with appropriate modifications as follows.
In the first embodiment and the second embodiment, the first side plate 22 and the second side plate 23 may be attached to the vertical frame 3 so as to be directly rotatable, not to the base plate 21. . In the third and fourth embodiments, the first side plate 22 may be attached to the vertical frame 3 so as to be directly rotatable. As a result, the number of parts can be reduced by the amount of the base plate 21.
