Hereinafter, a roll screen, which is an embodiment of the shielding device, will be described with reference to the drawings.
[First Embodiment]
This roll screen is used, for example, as a partition between a room and a staircase. As shown in FIGS. 1 and 2, the roll screen 10 is attached to the installation portion 2 provided in the opening which is the entrance of the stairs when viewed from the room. Here, the front surface of the roll screen 10 faces the room side, and the rear surface faces the stairs 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 portion 11 attached to the installation portion 2 and a screen 12 hanging from the head portion 11. The screen 12 functions as a shielding member in the present disclosure. The head portion 11 is attached to the installation portion 2 via the bracket 4. The head portion 11 is provided with side covers 11b at both ends in the width direction. The side cover 11b rotatably supports a take-up pipe 11a as a take-up shaft around which the screen 12 is wound. As shown in FIG. 3, the take-up pipe 11a 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 unit. The operation chain 14 is hung from one end of the head portion 11 in the width direction, and two chains constituting the operation chain 14 are hung. The operation chain 14 rotates the take-up pipe 11a in the pull-out direction of the screen 12 or in the take-up direction of the screen 12 by pulling down one of the two chains. As a result, the screen 12 is moved up and down together with the weight bar 15.

As an example, the screen 12 is resin-coated with a soft resin material such as polyvinyl chloride in order to improve the durability of a flexible sheet such as a strip-shaped cloth as a whole. The upper end of the screen 12 is fixed to the take-up pipe 11a, and the lower end is attached with a weight bar 15 that stabilizes the position of the screen 12 along 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 the end portion 12a (see FIG. 1) extending in the vertical direction between the screen 12 and the weight bar 15. The head portion 11 includes a shield 16 that closes a gap generated around the take-up pipe 11a. As an example, the shield 16 hangs down from the upper part to the lower part on the front surface of the head portion 11 on the room side. Since the diameter of the winding portion around which 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. Changes. When the weight bar 15 is lowered, the winding portion has a smaller diameter, so that the gap around the winding pipe 11a becomes larger. The shield 16 closes such a gap regardless of the winding amount of the screen 12 in the take-up pipe 11a, makes it difficult for air to flow between the room and the stairs, and improves the light-shielding property.

Further, the weight bar 15 includes a magnet 17 as a holding portion (see FIG. 1). Further, the magnetic body 6 is arranged at a position where the weight bar 15 of the floor 5 faces each other. As an example, the magnet 17 is a magnet sheet arranged along the width direction at the lowermost end, and when 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 attraction force. This makes it difficult for a gap to be formed between the weight bar 15 and the floor 5 at the lower limit position.

The roll screen 10 having the above-mentioned basic configuration includes a closing mechanism 20 for closing the gap between the vertical frame 3 and the end portion 12a of the screen 12. As shown in FIG. 4, the closing mechanism 20 is provided in the vertical frames 3 on both sides in the width direction, and each closing mechanism 20 is provided with respect to the base plate 21 fixed to the surface of the vertical frame 3 and the base plate 21. It is rotatable and includes a first side plate 22 and a second side plate 23 that extend in the vertical direction. As an example, the base plate 21 extends from the floor 5 to the take-up pipe 11a. The upper ends of the first side plate 22 and the second side plate 23 are, for example, the maximum when the weight bar 15 is in the upper limit position and the winding portion in which the screen 12 is wound on the winding pipe 11a has the maximum outer diameter. It is located slightly below the winding part of the outer diameter, that is, as high as possible so as not to interfere. Further, the lower end is, for example, a position close to the floor 5.

As shown in FIG. 5A, the base plate 21 is a fixing plate 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 base plate 21 is integrated into the vertical frame 3 by inserting the screw 24a into the mounting hole 24 and tightening the screw 24a to the vertical frame 3. The first side plate 22 and the second side plate 23 are rotatably attached to the base plate 21 so as to extend in the vertical direction at the 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 central position in the front-rear direction. It is equipped with. The first rotation support portion 25 is a cylindrical portion constituting a shaft hole through which the first rotation shaft 25a (see FIG. 4) is inserted, and the second rotation support portion 26 is a second rotation shaft 26a. (See FIG. 4) is a tubular portion constituting a shaft hole through which (see FIG. 4) is inserted. On both sides of the first rotation support portion 25 and the second rotation support portion 26 in the vertical direction, the first rotation portion 28 of the first side plate 22 and the second rotation portion 29 of the second side plate 23 are arranged. It 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 close the gap between the end portion 12a and the base plate 21 at the portion overlapping the end portion 12a of the screen 12. As an example, the first side plate 22 is located in the space on the room side with respect to the screen 12, and the second side plate 23 is located in the space on the stairs 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 arranged in a support recess 27 on one long side. The second side plate 23 is provided with a second rotating portion 29 arranged in the support recess 27 on one long side.

The first rotating portion 28 and the second rotating portion 29 are shaft insertion portions composed of cylindrical portions constituting the shaft holes, and the first rotating portion 28 is a first rotating support portion 25. The axes are aligned and the first rotating shaft 25a is inserted. Further, the axis of the second rotation portion 29 coincides with that of the second rotation support portion 26, and the second rotation shaft 26a is inserted through the second rotation portion 29. The first side plate 22 is centered on the first rotation shaft 25a within a range of approximately 90 ° 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. Rotate. The second side plate 23 is also centered on the second rotation shaft 26a within a range of approximately 90 ° between the open position substantially parallel to the base plate 21 and the closed position substantially perpendicular to the base plate 21. 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 take-up pipe 11a in the front-rear direction, that is, between the screen 12 and the take-up pipe 11a. It is located between the center of rotation 11c and the virtual vertical plane that hangs down. That is, the first side plate 22 is located between the screen 12 and the rotation center 11c of the take-up pipe 11a when the first side plate 22 is in the closed position substantially perpendicular to the base plate 21. The center of rotation 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 way are in a closed position substantially perpendicular to the base plate 21, the end portion 12a of the screen 12 is sandwiched between them. Further, when the open position is substantially parallel to the base plate 21, the first side plate 22 and the second side plate 23 face each other outward, that is, the first rotating portion 28 and the second rotating portion 29. The free ends on the opposite side of the are positioned so as to be separated from each other (facing the opposite side).

The first rotating portion 28 includes a first gear portion 28a around the first rotating portion 28, and the second rotating portion 29 includes a second gear portion 29a around the first gear portion 28a and the second gear portion 29a. Are in mesh with each other. As a result, the first side plate 22 and the second side plate 23 are interlocked with each other. 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 so that the distance between the tip portions when in the closed position is shorter than the length in the width direction of the weight bar 15. As a result, the screen 12 and the weight bar 15 can be raised and lowered even when the first side plate 22 and the second side plate 23 are in the closed position.

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 support recess 27 of the base plate 21 is combined with the first rotating portion 28 of the first side plate 22 and the second rotating portion 29 of the second side plate 23. Then, the first rotation shaft 25a is inserted into the first rotation support portion 25 and the first rotation portion 28. Further, the second rotation shaft 26a is inserted into 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 operates the operation chain 14 to move the screen 12 up and down 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 ends of the weight bar 15 smoothly move up and down without contacting the first side plate 22 and the second side plate 23, and the screen 12 Also, it goes up and down smoothly. The opening at the boundary between the room where the roll screen 10 is installed and the stairs is not narrowed and does not become difficult to pass because the first side plate 22 and the second side plate 23 are in the open positions.

Then, when partitioning the room from the stairs, first, the operation chain 14 is operated to lower the weight bar 15 to the lower limit position, and the screen 12 partitions the two spaces. In this state, the weight bar 15 is magnetically attracted to the floor 5, so that the formation of a gap between the weight bar 15 and the floor 5 is suppressed.

As shown in FIG. 6B, with the weight bar 15 in the lower limit position, one of the side plates 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 from the open position to the closed position in the closing direction. As a result, the end portion 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 portion 12a and the base plate 21 is closed. Here, when the weight bar 15 is lowered, the gap around the take-up pipe 11a becomes large, and this gap is closed by the shield 16.

As an example, when the first side plate 22 and the second side plate 23 are in the closed position, the relationship between the end portion 12a and the first side plate 22 and the second side plate 23 impairs the convenience of raising and lowering the screen 12. The screen is only lightly touched so as not to interfere with the raising and lowering of the screen 12. 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 operating force of the operation chain 14 for raising and lowering the screen 12 and the weight bar 15 may be slightly heavier, the screen 12 And the weight bar 15 can be raised and lowered.

Further, as an example, the relationship between the end portion 12a and the first side plate 22 and the second side plate 23 is such that the end portion 12a 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 holding force sufficient to prevent the screen 12 and the weight bar 15 from moving up and down. This makes it difficult to raise and lower the screen 12 and the weight bar 15 when the first side plate 22 and the second side plate 23 are in the closed position, but the end portion 12a, the first side plate 22, and the second side plate 23 It becomes difficult for a gap to be formed between the two, and it becomes difficult for air to escape.

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

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 so that the end portion 12a and the base plate 21 The gap between them can be prevented. As a result, the air flow between the space of the room and the space of the stairs is blocked, and the airtightness can be improved. Further, even if the screen 12 is pushed from one space by a difference in wind or atmospheric pressure, a hand, or the like, the end portion 12a is sandwiched between the first side plate 22 and the second side plate 23, so that there is a gap. Is less likely to be formed.

(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 one of the side plates. .. That is, when the weight bar 15 is in the lower limit position, even when the space is partitioned by the screen 12, the second side plate 23 can be moved by simply rotating the first side plate 22 from the room side. It can be rotated, and the first side plate 22 can be rotated only by rotating the second side plate 23 from the stairs side. This makes it possible to improve operability.

(1-3) When the weight bar 15 is in the lower limit position, the weight bar 15 is magnetically attracted to the floor 5 to suppress 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 take-up 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 the upper limit position). Become. Therefore, even if the weight bar 15 becomes the lower limit position and the gap between the winding portion and the upper end portion of the first side plate 22 becomes large, the gap can be made as small as possible, and the space between the room and the stairs It is possible to make it difficult for air to flow between them.

(1-5) In the head portion 11, the gap around the take-up pipe 11a can be closed by the shield 16 including the gap of (1-4) above. As a result, regardless of the diameter of the winding portion, the gap around the winding portion can be closed, and it becomes difficult for air to flow between the space of the room and the space of the stairs.

[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 take-up pipe of the screen 12 is provided with a drive gear 42 coaxial with the take-up pipe and the rotation 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 on the front substrate 41a with respect to the drive gear 42. The front pulley gear 43 is connected to the drive gear 42 via the 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 46a extending from the head unit 11 to the stairs side. A rear pulley gear 47 and a rear intermediate gear 48 are pivotally supported on the rear substrate 46a 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 raised and lowered by using the front operation unit 41. Further, when the weight bar 15 is in 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 weight bar 15 can be raised and lowered by 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 supporting means for supporting the end portion 12a of the screen 12, and instead magnetically attracts the end portion 12a to the first side plate 22. It is a composition. 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 portion 12a of the screen 12. The magnetic material sheet 52 may be a soft magnetic material sheet or a magnet sheet.

Further, as shown in FIG. 9, the rotation center of the first side plate 22 is between the screen 12 and the rotation center 11c of the take-up pipe 11a in the front-rear direction, that is, the rotation center 11c of the screen 12 and the take-up 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. As described above, the position of the first side plate 22 is preferably such that when it is in the closed position, it comes into contact with the end portion 12a of the screen 12 hanging from the head portion 11. This is because the gap between the end portion 12a and the first side plate 22 becomes smaller, and magnetic attraction is more likely to occur.

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. By keeping the first side plate 22 in the open position in the position where the weight bar 15 is raised, the opening at the boundary between the room where the roll screen 50 is installed and the stairs is not narrowed, and it is easy to pass through. Be maintained. The weight bar 15 is preferably raised and lowered when the first side plate 22 is in the open position, but it is also possible when the first side plate 22 is 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 in the lower limit position, the end portion 12a of the screen 12 is magnetically attracted to the magnet sheet 51 of the first side plate 22 so that the magnetic sheet 52 is magnetically attracted to the first side plate 22. Supported by. Even with such a configuration, the gap between the base plate 21 and the end portion 12a of the screen 12 can be closed.

(3-2) Even in such a roll screen 50, the weight bar 15 is raised and lowered when the first side plate 22 is in the open position. As a result, the magnetic material sheet 52 at the end portion 12a 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 the virtual vertical plane hanging from the rotation axis of the take-up pipe 11a. That is, the first side plate 22 is located closer to the room than the screen 12. Therefore, when viewed from the stairs side, the first side plate 22 is hidden by the end portion 12a of the screen 12, and the appearance is improved. When viewed from the room side, it is possible to visually recognize that the first side plate 22 is in the closed position, and it is possible to visually recognize that the gap between the screen 12 and the base plate 21 is closed. Further, from the room side, the rotation operation of the first side plate 22 can be easily performed.

(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 in the upper limit position), the winding portion. It will be in a position close to. Therefore, even if the weight bar 15 becomes the lower limit position and the gap between the winding portion and the upper end portion of the first side plate 22 becomes large, the gap can be made as small 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 as compared with the case where the first side plate 22 is arranged on the opposite side (staircase side) of the winding pipe 11a with respect to the screen 12. can do. Further, the winding portion and the upper end portion of the first side plate 22 are more closely connected to each other than when the first side plate 22 is arranged on the side opposite to the screen 12 suspended from the winding pipe 11a (room side). The gap can be reduced.

(3-5) The gap between the winding portion and the upper end portion of the first side plate 22 can be closed by the shielding body 16.
(3-6) Since the base plate 21 only needs to rotatably support only the first side plate 22, the width in the front-rear direction is narrower than that in the case of rotatably supporting two side plates. It can be miniaturized.

[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 material is locked to the end portion 12a of the screen 12.

The roll screen 60 as described above can obtain the effects listed as follows.
(4-1) The end portion 12a of the screen 12 is simply provided with staples 62 instead of the magnetic sheet 52. Therefore, when the screen 12 is wound around the take-up pipe, it is possible to prevent both ends in the width direction from becoming larger in diameter than the central portion and prevent winding misalignment.

The roll screen as described above can be further modified as appropriate as follows.
-In the first embodiment and the second embodiment, the first side plate 22 and the second side plate 23 may be directly rotatably attached to the vertical frame 3 instead of to the base plate 21. .. Further, in the third embodiment and the fourth embodiment, the first side plate 22 may be directly rotatably attached to the vertical frame 3. As a result, the number of parts can be reduced by the amount of the base plate 21.

The shield 16 provided on the head portion 11 may be provided on the front surface of the head portion 11, may be provided on the rear surface, or may be provided on the front surface and the rear surface.
