Description

The present invention relates to a solar radiation shielding device in which a mounting frame is attached to a ceiling, a wall or a window frame, and a shielding body hanging from the mounting frame can be raised and lowered. More specifically, the present invention relates to a solar shielding device suitable for reducing or preventing light leakage from a window of a corner portion by a shielding body hanging from a mounting frame along two wall surfaces sandwiching the corner portion.

Conventionally, the shielding material is suspended from the support member fixed to the fixed surface so as to be able to move up and down, and the hanging position of the shielding material with respect to the fixed surface when the shielding material is lowered is the support member. A blind configured to vary in the longitudinal direction of is disclosed (see, eg, Patent Document 1). In this blind, the shielding material is lifted and lowered with the lifting and lowering of the lifting cord that can be lifted and lowered from the supporting member, and the drum that can wind the lifting cord moves in the longitudinal direction of the supporting member, so that the lifting cord is lifted from the supporting member. The hanging position of the elevating cord moves in the longitudinal direction, and the shielding material is configured to move integrally with the elevating cord.

In the blind configured in this way, when moving in the longitudinal direction in the entire section of raising and lowering the slats (shielding material), when the slats are raised to the upper limit position, the adjacent slats are separated from each other to the maximum. A gap similar to the gap between adjacent headboxes is formed, and as the slats descend, the slats move in the direction of the adjacent slats, the gap between the adjacent slats gradually becomes smaller, and the slats are at the lower limit. When it descends to the position, the gap between adjacent slats is closed. Further, when the support member is fixed to the window frame or the like by a bracket or the like and the two head boxes are arranged so as to be movable in the longitudinal direction in the support member, the adjacent head boxes are adjacent to each other when the slats are lowered to the lower limit position. By moving in the direction of approaching each other, the gap between adjacent slats is closed. Therefore, since the hanging position of the slat with respect to the fixed surface when the slat is raised is different from the hanging position of the slat with respect to the fixed surface when the slat is lowered, the hanging position of the slat is supported when the slat is lowered. By changing the member in the longitudinal direction, the slats approach the window frame and the gap between the slats and the window frame becomes smaller, and the adjacent slats approach each other and the gap between the slats becomes smaller, so that light leakage can be prevented.

On the other hand, the ascending / descending shielding material is hung by the hanging means, the end portion of the shielding material is shielded by the band-shaped shielding material, and the band-shaped shielding material is integrally provided with the hanging means. The shielding device supported by the above is disclosed (see, for example, Patent Document 2). In this shielding device, the strip-shaped shielding material is supported by the strip-shaped shielding material holding means so as to be movable relative to the hanging means. Further, the band-shaped shielding material or the support member of the band-shaped shielding material may be configured to be pulled in the moving direction with a string or the like, whereby the band-shaped shielding material can be moved without being pulled directly. Further, when the shield and the strip-shaped shield are formed in a honeycomb shape, a notch is formed on the base end side of the strip-shaped shield material with a predetermined length, and a long hole is formed on the joint piece in the state of being formed in the honeycomb shape. The lifting cord is inserted through the elongated hole.

In the shielding device configured in this way, it is possible to adjust the amount of lighting and air permeability into the room by using a band-shaped shielding material that can close the gap when the shielding material is fully closed, and the installation workability of the band-shaped shielding material is possible. Can be improved.

However, in the blinds shown in the conventional patent document 1, since the slats are moved in the longitudinal direction to close the gap, a pair of blinds are provided along both wall surfaces sandwiching the corner portion of the room. In this case, when the slat of the pair of blinds is moved toward the corner portion in the longitudinal direction in an attempt to close the gap in the corner portion of the room, there is a problem that the gap on the side opposite to the corner portion becomes large. Further, in the blind shown in FIG. 5B of the conventional Patent Document 1, a pair of support members are provided along the two wall surfaces sandwiching the corner portion of the room, and a pair of shielding members are hung on these support members. In this state, even if the shielding material and the supporting member move back and forth or rotate, the supporting members come into contact with each other, so that the shielding materials cannot approach each other and a gap is generated, and light leaks from this gap. There was also. On the other hand, in the shielding device shown in the conventional Patent Document 2, when one elevating cord is inserted through the band-shaped shielding body, when the band-shaped shielding material is pulled in the moving direction with a string or the like, the band-shaped shielding material is laterally inserted. When moving, there is a problem that the band-shaped shielding material is caught by the shielding material depending on the position of the shielding material and cannot move smoothly. Further, in the shielding device shown in the above-mentioned conventional patent document 2, when one elevating cord is inserted through the band-shaped shielding body, the shielding material is moved by a string to attach the string formed on the shielding material. There is also a problem that stress is applied to the contact portion between the hole and the string, and the string attachment hole becomes large due to the stress depending on the fabric.

In the solar radiation shielding device according to the first aspect of the present invention, the shielding body is configured to be movable in the front-rear direction of the shielding body or to be rotatable in a horizontal plane around one end of the mounting frame or the shielding body. When a pair of mounting frames are mounted along two wall surfaces sandwiching a corner portion, the distance between the side edges of the pair of shields hanging from the pair of mounting frames and the corner portion of the room is hardly changed. Of the side edges of the pair of shields, the side edges on the corner portion side approach or come into contact with each other, so that the gap between the corner portions of the room can be closed. As a result, without using an auxiliary band-shaped shield, the light leakage from the side edge of the pair of shields on the side opposite to the corner of the room was maintained unchanged. Light leakage from the corner window can be reduced or prevented. Further, since the horizontal length of the shield is formed to be larger than the length of the mounting frame, a pair of mounting frames are mounted along the two wall surfaces sandwiching the corners of the room, and the shield or the mounting frame moves back and forth. Alternatively, even if it rotates, the mounting frames do not come into contact with each other. As a result, light leakage from the window at the corner of the room can be reduced or prevented by the one end of the shield approaching or abutting.

In the solar shielding device according to the second aspect of the present invention, when the corner portion of the room is a concave corner portion, the first shielding body moves in the front-rear direction of the first shielding body so as to be separated from one wall surface. One end of the first and second shields approaches by the movement or the movement of either or both of the second movements in which the second shield moves in the anteroposterior direction of the second shield so as to move away from the other wall surface. Alternatively, since they come into contact with each other, the gaps in the corners of the room can be closed by the first and second shields. As a result, light leakage from the window at the corner of the room can be reduced or prevented. Further, when the corner portion of the room is a convex corner portion, the first movement in which the first shield moves in the front-rear direction of the first shield so as to approach one wall surface, or the second shield is the other. Since one end of the first and second shields approaches or comes into contact with one or both of the second movements that move in the front-rear direction of the second shield so as to approach the wall surface, the corner portion of the room The gap can be closed by the first and second shields. As a result, light leakage from the window at the corner of the room can be reduced or prevented. Further, regardless of whether the corner portion of the room is a concave corner portion or a convex corner portion, the first and second shields do not move in these longitudinal directions, that is, of the first and second shields. Since the distance between the side edges and the corners of the room hardly changes, light leakage can be maintained unchanged from the side edges of the first and second shields opposite to the corners. Further, since the horizontal lengths of the first and second shields are formed to be larger than the lengths of the first and second mounting frames, the mounting frames do not come into contact with each other even if the shield or the mounting frame moves back and forth. .. As a result, light leakage from the window at the corner of the room can be reduced or prevented by the one end of the shield approaching or abutting.

In the solar shielding device according to the third aspect of the present invention, when the corner portion of the room is a concave corner portion, the first mounting frame or the first shield is centered on one end of the first mounting frame or the first shield. A first rotation in which the end rotates away from one wall surface, or the other end of the second mounting frame or second shield is from the other wall surface around one end of the second mounting frame or second shield. The other end of the first and second shields approaches or abuts due to the rotation of either one or both of the second rotations that rotate so as to separate, so that the gaps in the corners of the room are first and second. 2 Can be blocked by a shield. As a result, light leakage from the window at the corner of the room can be reduced or prevented. When the corner portion of the room is a convex corner portion, the first mounting frame or the other end of the first shield is rotated around one end of the first mounting frame or the first shield so as to approach one wall surface. The first rotation that moves, or the second rotation that rotates around one end of the second mounting frame or the second shield so that the other end of the second mounting frame or the second shield approaches the other wall surface. Since the other ends of the first and second shields approach or abut by the rotation of either one or both of the movements, the gaps in the corners of the room can be closed by the first and second shields. As a result, light leakage from the window at the corner of the room can be reduced or prevented. Further, regardless of whether the corner portion of the room is a concave corner portion or a convex corner portion, the first and second shields hardly move in the longitudinal direction thereof, that is, the first and second shields. Since the distance between both side edges of the room and the corner portion of the room hardly changes, light leakage can be maintained unchanged from the side edge of both side edges of the first and second shields opposite to the corner portion. Further, since the horizontal lengths of the first and second shields are formed to be larger than the lengths of the first and second mounting frames, the mounting frames do not come into contact with each other even if the shield or the mounting frame rotates. .. As a result, light leakage from the window at the corner of the room can be reduced or prevented by the one end of the shield approaching or abutting.

In the solar radiation shielding device according to the fourth aspect of the present invention, since the bottom rail is formed shorter than the shielding body, when a pair of mounting frames are mounted along the two wall surfaces sandwiching the corner portion of the room, the shielding body is moved back and forth. The bottom rails do not come into contact with each other when one ends of the shield approach each other by moving in a direction or rotating around one end. As a result, although light leakage occurs from the gap between the bottom rails, it is possible to prevent one end of the shield from approaching or hindering contact due to contact between the bottom rails, and it is possible to reduce or prevent light leakage from between the shields. ..

The pair of boss members is transmitted to the pair of male threaded shafts via the transmission side worm and the pair of male screw side worm wheels, and the pair of male threaded shafts rotate to cause the pair of boss members together with the second mounting frame 12 in FIG. 4 (b). ), That is, it moves in the direction away from the wall surface 63 extending in the vertical direction (forward). As a result, one ends of the first and second mounting frames 11 and 12 approach each other, and one ends of the first and second slat groups 21 and 22 approach or abut against each other, so that the concave corner portion 61 of the room The gap can be closed by the first and second slat groups 21 and 22. Therefore, light leakage from the window of the concave corner portion 61 of the room can be reduced or prevented.

The operation of the horizontal blind 10 thus attached and used will be described. Since the first and second slat groups 21 and 22 do not move in these longitudinal directions, that is, the distance between both side edges of the first and second slat groups 21 and 22 and the concave corner portion 61 of the room hardly changes. Light leakage can be maintained unchanged from the side edges of the first and second slat groups 21 and 22 opposite to the concave corner portion 61. Further, since the horizontal lengths of the first and second slat groups 21 and 22 are formed to be larger than the lengths of the first and second mounting frames 11 and 12, respectively, the first and second mounting frames 11 and 12 are the first. Even if the first and second slat groups 21 and 22 are moved forward together with the first and second slat groups 21 and 22, the first and second mounting frames 11 and 12 do not come into contact with each other. As a result, when one ends of the first and second slat groups 21 and 22 approach or come into contact with each other, light leakage from the window of the concave corner portion 61 of the room can be reduced or prevented. Further, since the lengths of the first bottom rail 31 and the second bottom rail are formed shorter than the horizontal lengths of the first and second slat groups 21 and 22, the first and second mounting frames 11 and 12 are first. Even if the first and second slat groups 21 and 22 are moved forward together with the second slat groups 21 and 22, the first bottom rail 31 and the second bottom rail do not come into contact with each other. As a result, when one ends of the first and second slat groups 21 and 22 approach or come into contact with each other, light leakage from the window of the concave corner portion 61 of the room can be reduced or prevented.

As a result, one end of the second mounting frame 12 and one end of the first mounting frame 11 are located relatively close to each other, and the other end of the second mounting frame 12 and the other end of the first mounting frame 11 are positioned apart from each other. .. Although not shown, below the two wall surfaces 67 and 68 sandwiching the convex corner portion 66, a window approaching the convex corner portion 66 or a window connected by the convex corner portion 66 is provided, respectively.

In order to prevent light leakage from the window of the convex corner portion 66, first, the elevating / tilting operation member 19 (FIG. 3) provided on the front surface of the first mounting frame 11 is operated to form a first slat group. After each of the slats 21a of 21 is raised and lowered to the lowest stage, the front-rear movement operating member 51 (FIG. 3) provided on the front surface of the first mounting frame 11 is operated. The front-rear movement pulley 46 (FIG. 5A) is rotated by the operation of the front-rear movement operation member 51, and the rotational force is applied to the pulley shaft 44, the pulley-side worm 53, as shown in FIGS. 1 and 2. It is transmitted to the pair of male threaded shafts 49 and 49 via the transmission side worm wheel 54, the transmission shaft 47, the pair of transmission side worms 56 and 56, and the pair of male screw side worm wheels 57 and 57, and these pair of male threaded shafts 49. As the wheels 49 rotate, the pair of boss members 48, 48 move together with the first mounting frame 11 in the direction of the broken line arrow in FIG. 5B, that is, in the direction (rearward) of approaching the wall surface 67 extending in the vertical direction.

Next, by operating the elevating / tilting operation member provided on the front surface of the second mounting frame 12, each slat 22a of the second slat group 22 is raised and lowered to the lowest stage, and then the second mounting frame 12 Operate the operation member for moving back and forth provided on the front surface of the. By operating the front-rear movement operation member, the front-rear movement pulley 46 (FIG. 5A) is rotated in the same manner as described above, and this rotational force is applied to the pulley shaft, the pulley side worm, the transmission side worm wheel, the transmission shaft, and a pair. The pair of boss members is transmitted to the pair of male threaded shafts via the transmission side worm and the pair of male threaded side worm wheels, and the pair of male threaded shafts rotate to cause the pair of boss members together with the second mounting frame 12 in FIG. 5 (b). ), That is, the direction of approaching the wall surface 68 extending in the lateral direction (rearward). As a result, one ends of the first and second mounting frames 11 and 12 approach each other, and one ends of the first and second slat groups 21 and 22 approach or abut against each other. Therefore, the convex corner portion 66 of the room The gap can be closed by the first and second slat groups 21 and 22. Therefore, light leakage from the window of the convex corner portion 66 of the room can be reduced or prevented. The action of the horizontal blind 10 attached and used in this way is the same as that of the above-mentioned (1-1) "when the horizontal blind 10 is provided so as to sandwich the concave corner portion 61 of the room", so that it is repeated. The explanation of is omitted.

It's a stick. Other than the above, the configuration is the same as that of the first embodiment.

The mounting method, usage method, and operation of the horizontal blind 80 configured in this manner will be described.
(2-1) When the horizontal blind 80 is provided so as to sandwich the concave corner portion 61 of the room As shown in FIG. 10A, when the corner portion of the room is concave, the first mounting frame 81 is concave in the room. It is attached to the ceiling 15 along the wall surface 62 (one wall surface) extending in the lateral direction among the two wall surfaces 62 and 63 sandwiching the corner portion 61. At this time, one end of the first mounting frame 81 to which the support stay 92 is mounted is separated from the concave corner portion 61, and the other end to which the adsorbed member 94 is fitted is close to the concave corner portion 61. Then, the first mounting frame 81 is mounted on the ceiling 15. Further, the second mounting frame 82 is mounted on the ceiling 15 along the wall surface 63 (the other wall surface) extending in the vertical direction among the two wall surfaces 62 and 63 sandwiching the concave corner portion 61 of the room. At this time, one end of the second mounting frame 82 to which the support stay 92 is mounted is separated from the concave corner portion 61, and the other end to which the adsorbed member 94 is fitted is close to the concave corner portion 61. Then, the second mounting frame 82 is mounted on the ceiling 15. As a result, the other end of the second mounting frame 82 and the other end of the first mounting frame 81 are located relatively close to each other, and one end of the second mounting frame 82 and one end of the first mounting frame 81 are separated from each other. .. Although not shown, below the two wall surfaces 62 and 63 sandwiching the concave corner portion 61, a window approaching the concave corner portion 61 or a window connected by the concave corner portion 61 is provided, respectively.

In order to prevent light leakage from the window of the concave corner portion 61, first, as shown in FIG. 10A, by operating the elevating cord 99 hanging from the front right portion of the first mounting frame 81. By lowering each slat 21a of the first bottom rail 31 and the first slat group 21 to the lowest stage and operating the tilting operation rod 101 rotatably mounted on the front right portion of the first mounting frame 81. After each slat 21a of the first slat group 21 is erected, the rotation operating rod 104 provided on the front left portion of the first mounting frame 81 is pulled toward the front. By operating the rotating operation rod 104, the first mounting frame 81 extends in the direction indicated by the broken line arrow in FIG. 10B about the support shaft 91, that is, the other end of the first mounting frame 81 extends laterally. The member 94 to be adsorbed, which rotates in the direction away from (forward) and is fitted near the other end of the first mounting frame 81, comes into contact with the adsorbing member 97 on the indoor side and stops. At this time, the protrusion 98 projecting from the lower surface of the movable piece 93b of the slide rail 93 moves in a direction orthogonal to the wall surface 62 extending in the lateral direction, whereas the first mounting frame 81 is centered on the support shaft 91. The amount of deviation caused by the arc motion is absorbed by the protrusion 98 moving in the elongated hole 94a in the longitudinal direction (FIGS. 7 and 8). As a result, the first mounting frame 81 rotates smoothly around the support shaft 92. Further, since the suction member 94 is attracted to the indoor suction member 97 by a magnetic force, the first mounting frame 81 does not unintentionally rotate in the direction of approaching the wall surface 62.

Next, as shown in FIG. 10A, each slat 22a of the second bottom rail and the second slat group 22 is operated by operating the elevating cord 99 hanging from the front left portion of the second mounting frame 82. After lowering to the lowest stage and operating the tilt operation rod 101 rotatably attached to the front left portion of the second attachment frame 82, each slat 22a of the second slat group 22 is erected, and then the second slat 22a is erected. Pull the rotation operation rod 104 provided on the right side of the front surface of the mounting frame 82 toward you. By operating the rotating operation rod 104, the second mounting frame 82 extends in the direction indicated by the alternate long and short dash arrow in FIG. 10B about the support shaft 92, that is, the other end of the second mounting frame 82 extends in the vertical direction. The member 94 to be adsorbed, which rotates in the direction away from 63 (forward) and is fitted near the other end of the second mounting frame 82, comes into contact with the adsorbing member 97 on the indoor side and stops. At this time, the protrusions protruding from the lower surface of the movable piece of the slide rail 93 move in the direction orthogonal to the wall surface 63 extending in the vertical direction, whereas the second mounting frame 82 moves in an arc centered on the support shaft 91. The amount of deviation caused by the above is absorbed by the protrusion moving in the elongated hole in the longitudinal direction. As a result, the second mounting frame 82 rotates smoothly around the support shaft 91. Further, since the suction member 94 is attracted to the indoor suction member 97 by a magnetic force, the second mounting frame 82 does not unintentionally rotate in the direction of approaching the wall surface 63. As a result, the other ends of the first and second mounting frames 81 and 82 approach each other, and the other ends of the first and second slat groups 21 and 22 approach or abut against each other, so that the concave corner portion of the room The gap of 61 can be closed by the first and second slat groups 21 and 22. Therefore, light leakage from the window of the concave corner portion 61 of the room can be reduced or prevented.

The operation of the horizontal blind 80 thus attached and used will be described. The first and second slat groups 21 and 22 hardly move in these longitudinal directions, that is, the distance between both side edges of the first and second slat groups 21 and 22 and the concave corner portion 61 of the room hardly changes. , The light leakage can be maintained unchanged from the side edge of the first and second slat groups 21 and 22 opposite to the concave corner portion 61. Further, since the horizontal lengths of the first and second slat groups 21 and 22 are formed to be larger than the lengths of the first and second mounting frames 81 and 82, respectively, the first and second mounting frames 81 and 82 are used. Even if the other ends of the first and second mounting frames 81 and 82 are separated from the wall surfaces 62 and 63 together with the other ends of the first and second slat groups 21 and 22, respectively, by rotating around one end of the first And the second mounting frames 11 and 12 do not come into contact with each other. As a result, when one ends of the first and second slat groups 21 and 22 approach or come into contact with each other, light leakage from the window of the concave corner portion 61 of the room can be reduced or prevented. Further, since the lengths of the first bottom rail 31 and the second bottom rail are formed shorter than the horizontal lengths of the first and second slat groups 21 and 22, the first and second mounting frames 81 and 82 are used for these. The first bottom even if the other ends of the first and second mounting frames 81 and 82 are separated from the wall surfaces 62 and 63 together with the other ends of the first and second slat groups 21 and 22, respectively, by rotating around one end. The rail 31 and the second bottom rail do not come into contact with each other. As a result, when one ends of the first and second slat groups 21 and 22 approach or come into contact with each other, light leakage from the window of the concave corner portion 61 of the room can be reduced or prevented.

(2-2) When the horizontal blind 80 is provided so as to sandwich the convex corner portion 66 of the room As shown in FIG. 11A, when the corner portion of the room is convex, the first mounting frame 81 is the room. It is attached to the ceiling 15 along the wall surface 67 (one wall surface) extending in the vertical direction among the two wall surfaces 67 and 68 sandwiching the convex corner portion 66 of the above. At this time, one end of the first mounting frame 81 to which the support stay 92 is mounted is separated from the convex corner portion 66, and the other end to which the adsorbed member 94 is fitted approaches the convex corner portion 66. In this state, the first mounting frame 81 is mounted on the ceiling 15. Further, the second mounting frame 82 is mounted on the ceiling along the wall surface 68 (the other wall surface) extending in the lateral direction among the two wall surfaces 67 and 68 that sandwich the convex corner portion 66 of the room. At this time, one end of the second mounting frame 82 to which the support stay 92 is mounted is separated from the convex corner portion 66, and the other end to which the adsorbed member 94 is fitted approaches the convex corner portion 66. In this state, the second mounting frame 82 is mounted on the ceiling. As a result, the other end of the second mounting frame 82 and the other end of the first mounting frame 81 are located relatively close to each other, and one end of the second mounting frame 82 and one end of the first mounting frame 81 are separated from each other. .. Although not shown, below the two wall surfaces 67 and 68 sandwiching the convex corner portion 66, a window approaching the convex corner portion 66 or a window connected by the convex corner portion 66 is provided, respectively.

In order to prevent light leakage from the window of the convex corner portion 66, first, as shown in FIG. 11A, the elevating cord 99 hanging from the front right portion of the first mounting frame 81 is operated. By lowering each slat 21a of the first bottom rail 31 and the first slat group 21 to the lowest stage, and operating the tilting operation rod 101 rotatably attached to the front right portion of the first mounting frame 81. After each slat 21a of the first slat group 21 is erected, the rotation operating rod 104 provided on the front left portion of the first mounting frame 81 is pushed toward the wall surface 67 extending in the vertical direction. By operating the rotating operation rod 104, the first mounting frame 81 extends in the direction indicated by the broken line arrow in FIG. 11B about the support shaft 91, that is, the other end of the first mounting frame 81 extends in the vertical direction 67. The member 94 to be attracted, which is fitted near the other end of the first mounting frame 81, abuts on the wall-side suction member 96 and stops. At this time, the protrusion 98 projecting from the lower surface of the movable piece 93b of the slide rail 93 moves in the direction orthogonal to the wall surface 67 extending in the vertical direction, whereas the first mounting frame 81 is centered on the support shaft 91. The amount of deviation caused by the arc motion is absorbed by the protrusion 98 moving in the elongated hole 94a in the longitudinal direction (FIGS. 7 and 8). As a result, the first mounting frame 81 rotates smoothly around the support shaft 91. Further, since the suction member 94 is magnetically attracted to the wall-side suction member 96, the first mounting frame 81 does not unintentionally rotate in the direction away from the wall surface 67.

Next, as shown in FIG. 11A, by operating the elevating cord 99 hanging from the front left portion of the second mounting frame 82, each slat 22a of the second bottom rail and the first slat group 22 is struck. After lowering to the lowest stage and operating the tilt operation rod 101 rotatably attached to the front left portion of the second attachment frame 82, each slat 22a of the second slat group 22 is erected, and then the second is 2 The rotation operation rod 104 provided on the right side of the front surface of the mounting frame 82 is pushed toward the wall surface 68 extending in the lateral direction. By the operation of the rotating operation rod 104, the second mounting frame 82 extends in the direction indicated by the alternate long and short dash arrow in FIG. 11B about the support shaft 91, that is, the other end of the second mounting frame 82 extends laterally. It rotates in the direction approaching 68 (rearward), and the adsorbed member 94 fitted near the other end of the second mounting frame 82 abuts on the wall-side adsorption member 96 and stops. At this time, the protrusions protruding from the lower surface of the movable piece of the slide rail 93 move in the direction orthogonal to the wall surface 68 extending in the lateral direction, whereas the second mounting frame 82 moves in an arc centered on the support shaft 91. The amount of deviation caused by the above is absorbed by the protrusion moving in the elongated hole in the longitudinal direction. As a result, the second mounting frame 82 rotates smoothly around the support shaft 91. Further, since the suction member 94 is magnetically attracted to the wall-side suction member 96, the second mounting frame 82 does not unintentionally rotate in the direction away from the wall surface 68. As a result, the other ends of the first and second mounting frames 81 and 82 approach each other, and the other ends of the first and second slat groups 21 and 22 approach or abut against each other, so that the convex corners of the room The gap between the portions 66 can be closed by the first and second slat groups 21 and 22. Therefore, light leakage from the window of the convex corner portion 66 of the room can be reduced or prevented. The operation of the horizontal blind 80 attached and used in this way is the same as that of the above (2-1) "when the horizontal blind 80 is provided so as to sandwich the concave corner portion 61 of the room", so that it is repeated.
