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 shield hanging from the mounting frame is configured to be capable of moving up and down. More particularly, the present invention relates to a solar radiation shielding device suitable for reducing or preventing light leakage from a corner window by means of a shield suspended respectively from mounting frames along two wall surfaces sandwiching the corner.

  Conventionally, the shielding member is suspended from the supporting member fixed to the fixed surface so as to be able to move up and down, and the hanging position of the shielding member relative to the fixed surface is the supporting member when the shielding member is lowered. Patent Document 1 discloses a blind configured to change in the longitudinal direction of the window. In this blind, the shielding member is moved up and down along with the lifting and lowering of the lifting cord suspended from the supporting member so as to be lifted and lowered, and the drum capable of taking up the lifting cord moves in the longitudinal direction of the support member. The hanging position of the lifting cord moves in the longitudinal direction, and the shielding member moves integrally with the lifting cord.

  In the blind configured as described above, when moving in the longitudinal direction in the entire section of lifting and lowering of the slat (the shielding material), adjacent slats are maximally separated from each other when the slat is raised to the upper limit position, A gap of about the same distance as the gap between adjacent head boxes is formed, and the slats move in the adjacent slat direction as the slat descends, and the gap between adjacent slats gradually decreases, and the slats become lower limit When lowered to the position, the gap between the adjacent slats is closed. When the support member is fixed to the window frame or the like by a bracket or the like, and two head boxes are movably disposed in the support member in the longitudinal direction, the head boxes adjacent to each other when the slat descends to the lower limit position. By moving in a direction in which they approach each other, the gap between adjacent slats is closed. Therefore, since the hanging position of the slat with respect to the fixed surface in the raised state of the slat is different from the hanging position of the slat with respect to the fixed surface in the lowered state of the slat, the hanging position of the slat is supported in the lowered state. By changing in the longitudinal direction of the member, the slats approach the window frame, the gap between the slats and the window frame decreases, and the adjacent slats approach each other, the gap between the slats decreases, and light leakage can be prevented.

  On the other hand, a vertically movable shielding member is suspended by the drooping means, an end of the shielding material is shielded by the strip shielding material, and the strip shielding material is a strip shielding material holding means or shielding member integrally provided to the drooping unit. U.S. Pat. No. 5,958,015 discloses a shielding device supported by the U.S. Pat. In this shielding device, the band-shaped shielding material is supported by the band-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 by a cord or the like, whereby the band-shaped shielding material can be moved without being drawn directly. Furthermore, when the shielding body and the band-shaped shielding body are formed in a honeycomb shape, a cut is formed with a predetermined length on the base end side of the band-shaped shielding material, and a long hole is formed on a bonding piece in a state formed in a honeycomb shape. The elevating cord is inserted into the long hole.

  In the shielding device configured in this way, it is possible to adjust the amount of light taken into the room and the air permeability by using the band-shaped shielding material capable of closing the gap in the fully closed state of the shielding material, and the installation workability of the band-shaped shielding material Can be improved.

  However, in the blind shown in the above-mentioned conventional Patent Document 1, since the slat is moved in the longitudinal direction to close the gap, a pair of blinds are respectively provided along both wall surfaces sandwiching the corner of the room. In this case, if the slats of the pair of blinds are moved toward the corner in the longitudinal direction in order to close the gap in the corner of the room, the gap on the opposite side to the corner becomes large. Further, in the blind shown in FIG. 5B of the conventional Patent Document 1 described above, a pair of support members are provided along the two wall surfaces sandwiching the corner portion of the room, and the pair of shielding members are suspended on these support members. In the state, even if the shielding member and the supporting member move back and forth or rotate, the supporting members contact with each other, so that the shielding members can not approach each other, a gap is generated, and light leaks from the gap There was also. On the other hand, in the case of the conventional shielding apparatus disclosed in Patent Document 2 above, when one lifting cord is inserted in the band-shaped shielding body, the band-shaped shielding material is horizontal when the band-shaped shielding material is pulled with a string or the like. When moving, depending on the position of the shielding material, there is a problem that the band-shaped shielding material is caught by the shielding material and can not be moved smoothly. Moreover, in the shielding apparatus shown by the said conventional patent document 2, when one raising / lowering cord is penetrated by the strip | belt-shaped shielding body, the string attachment formed in the shielding material by moving a shielding material by a string There is also a problem that stress is applied to the contact portion between the hole and the cord, and depending on the material, the cord attachment hole becomes large due to the stress.

  The first object of the present invention is to maintain light leakage from the side edge of the pair of shields opposite to the corner portion of the room without changing, without using the auxiliary strip shield. It is an object of the present invention to provide a solar radiation shielding device capable of reducing or preventing light leakage from the window at the corner portion of a room. A second object of the present invention is to provide a window at a corner portion of a room by one end of a shield approaching or abutting without the mounting frames coming into contact with each other even if the shield or mounting frame moves back and forth or pivots. It is an object of the present invention to provide a solar shading device capable of reducing or preventing light leakage from the light. A third object of the present invention is to provide a solar radiation shielding device capable of preventing light leakage from between shields due to contact between bottom rails, although there is slight light leakage between bottom rails.

  The second aspect of the present invention is an invention based on the first aspect, and further, as shown in FIGS. 1, 3 and 4, two mounting frames 11, 12 sandwiching a corner portion 61 of a room. The first mounting frame 11 attached to the ceiling 15, wall or window frame along one of the wall surfaces 62, 63, and the other of the two wall surfaces 62, 63 sandwiching the corner portion 61 of the room A second attachment frame 12 attached to the ceiling 15, wall or window frame along one end of the first attachment frame 11 so that the shields 21 and 22 are It has a first shield 21 suspended from the mounting frame 11 and a second shield 22 suspended from the second mounting frame 12 so that the first shield 21 is separated from one wall surface 62 or one In front of the first shield 21 so as to approach the wall surface 62 The first movement moving in the direction, or the second movement moving the second shield 22 in the front-rear direction of the second shield 22 so as to move away from the other wall surface 63 or approach the other wall surface 63 It is characterized in that one end of the first and second shields 21 and 22 approaches or abuts by movement of one or both.

  The third aspect of the present invention is the invention based on the first aspect, and further, as shown in FIGS. 6, 9 and 10, two mounting frames 81, 82 sandwich a corner portion 61 of a room. The first mounting frame 81 attached to the ceiling 15, wall or window frame along one of the wall surfaces 62 and 63, and the other wall surface of the two wall surfaces 62 and 63 sandwiching the corner portion 61 of the room And 63 a second mounting frame 82 mounted on the ceiling 15, wall or window frame and the other end of the second mounting frame 82 being provided close to the other end of the first mounting frame 81, 63. It has a first shield 21 hanging down from a first mounting frame 81 and a second shield 22 hanging down from a second mounting frame 82, and centered on one end of the first mounting frame 81 or the first shield. The other end of the first mounting frame 81 or the first shield is one The first rotation or the second attachment frame 82 or the second shield around one end of the second attachment frame 82 or the second shield, which pivots away from the wall surface 62 or approaches one wall surface 62 The first and second shields 21 and 22 are rotated by one or both of the second rotations which rotate so as to move the other end away from the other wall surface 63 or approach the other wall surface 63. And the other end of the two members is configured to approach or abut.

  The fourth aspect of the present invention is an invention based on any of the first to third aspects, and further, as shown in FIGS. 3 to 5, a bottom rail 31 is provided at the lower ends of the shields 21 and 22. The bottom rail 31 is formed shorter than the shield 21.

  In the solar radiation shielding apparatus according to the first aspect of the present invention, since the shielding body is movable in the front-rear direction of the shielding body or rotatable in a horizontal plane around one end of the mounting frame or the shielding body, When a pair of mounting frames are respectively attached along the two wall surfaces sandwiching the corner, the distance between the side edges of the pair of shields hanging down from the pair of mounting frames and the corner of the room hardly changes. A gap in a corner portion of the room can be closed by the side edges on the corner portion side of the both side edges of the pair of shields approaching or abutting on each other. As a result, without using the auxiliary strip shield, the light leakage from the side edge of the pair of shields opposite to the corner portion of the room is maintained unchanged. Light leakage from the corner window can be reduced or prevented. In addition, since the horizontal length of the shield is formed larger than the length of the mounting frame, a pair of mounting frames are mounted along the two wall surfaces sandwiching the corner of the room, and the shield or mounting frame moves back and forth Or even if it rotates, mounting frames do not contact. As a result, when one end of the shield approaches or abuts, light leakage from the window at the corner of the room can be reduced or prevented.

  In the solar radiation shielding apparatus according to the second aspect of the present invention, in the case where the corner of the room is a concave corner, the first shield moves in the front-rear direction of the first shield so as to be away from one wall surface. One end of the first and second shields approaches due to movement or movement of either one or both of the second movement of moving the second shield in the front-rear direction of the second shield so that the second shield moves away from the other wall. Or since it abuts, the clearance of the corner part 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. In addition, when the corner of the room is a convex corner, the first movement or the second shield moving in the front-rear direction of the first shield so that the first shield approaches one wall surface is the other. Since one end of the first and second shields approaches or abuts by the movement of one or both of the second movement of the second shield moving in the front-rear direction toward 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. In addition, even if the corner of the room is a concave corner or a convex corner, the first and second shields do not move in the longitudinal direction, that is, the first and second shields Since the distance between the side edges and the corner portion of the room hardly changes, it is possible to maintain the light leakage from the side edge of the first and second shields opposite to the corner portion without changing. Furthermore, since the horizontal length of the first and second shields is set larger than the length of the first and second mounting frames, the mounting frames do not contact each other even if the shield or the mounting frame moves back and forth . As a result, when one end of the shield approaches or abuts, light leakage from the window at the corner of the room can be reduced or prevented.

  In the solar radiation shielding apparatus according to the third aspect of the present invention, when the corner of the room is a concave corner, the other of the first mounting frame or the first shielding body is centered on one end of the first mounting frame or the first shielding body From the other wall, the other end of the second mounting frame or the second shielding body is centered on one end of the first mounting frame or the second mounting frame or the second shielding body in which the end is pivoted away from one wall surface As the second end of the first and second shields approaches or abuts due to the second and / or second pivoting, the second and third pivoting away from each other causes the gap between the corner portions of the room to become the first and the second 2 It can be closed 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 of the room is a convex corner, the other end of the first mounting frame or the first shielding body is turned so that the other end of the first mounting frame or the first shielding body approaches one wall surface centering on one end of the first mounting frame or the first shielding body A second rotation that moves the other end of the second mounting frame or the second shielding body so that the other end of the second mounting frame or the second shielding body approaches the other wall surface around one end of the first mounting moving frame or the second mounting frame or the second shielding body Since the other end of the first and second shields approaches or abuts due to the pivoting of either or both of the movements, the gap in the corner portion 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. Also, even if the corner portion of the room is either a concave corner portion or a convex corner portion, the first and second shields hardly move in the longitudinal direction, that is, the first and second shields. Since there is almost no change in the distance between the side edges of the room and the corner of the room, it is possible to maintain the light leakage from the side edges of the first and second shields opposite to the corner without changing. Furthermore, since the horizontal length of the first and second shields is set to be greater than the length of the first and second mounting frames, the mounting frames do not contact each other even if the shield or the mounting frame rotates. . As a result, when one end of the shield approaches or abuts, light leakage from the window at the corner of the room can be reduced or prevented.

  In the solar radiation shielding apparatus according to the fourth aspect of the present invention, since the bottom rail is formed shorter than the shield, when the pair of mounting frames are attached along the two wall surfaces sandwiching the corner of the room, the shield is front and back Moving in the direction or pivoting around one end, the bottom rails do not touch each other when the one end of the shield approaches one another. As a result, although light leakage occurs from the gap between the bottom rails, it is possible to prevent the contact between the bottom rails from interfering with the approach or abutment of the one end of the shield and reduce or prevent light leakage from between the shields. .

In the same manner as described above, the back-and-forth moving pulley 46 (FIG. 4A) is rotated by the operation of the back-and-forth moving operation member, and this rotational force is transmitted to the pulley shaft, pulley side worm, transmission side worm wheel, transmission shaft, pair 4 (b) together with the second mounting frame 12 by being transmitted to the pair of externally threaded shafts via the transmission side worm and the pair of externally threaded worm wheels, and the pair of externally threaded shafts being rotated. ), I.e., in the direction away from the longitudinally extending wall surface 63 (forward). As a result, the ends of the first and second mounting frames 11 and 12 approach each other, and the ends of the first and second slats 21 and 22 approach or abut each other. The gap can be closed by the first and second slat groups 21 and 22. Accordingly, light leakage from the window of the concave corner 61 of the room can be reduced or prevented.

  The operation of the horizontal blind 10 so mounted and used will now be described. Since the first and second slat groups 21 and 22 do not move in their longitudinal directions, ie, the distance between the side edges of the first and second slat groups 21 and 22 and the concave corner 61 of the room hardly changes, It is possible to maintain the light leakage from the side edges of the first and second slat groups 21 and 22 opposite to the concave corner 61 without changing the light leakage. In addition, since the horizontal length of the first and second slat groups 21 and 22 is larger than the length of the first and second mounting frames 11 and 12, respectively, the first and second mounting frames 11 and 12 Even if the first and second slat groups 21 and 22 move forward with the first and second slat groups 21 and 22, respectively, the first and second mounting frames 11 and 12 do not contact each other. As a result, when one end of the first and second slat groups 21 and 22 approaches or abuts, light leakage from the window of the concave corner portion 61 of the room can be reduced or prevented. Furthermore, since the lengths of the first bottom rail 31 and the second bottom rail are formed shorter than the lengths in the horizontal direction of the first and second slat groups 21 and 22, the first and second mounting frames 11 and 12 have the first length. The first bottom rail 31 and the second bottom rails do not contact each other even if they move forward of the first and second slat groups 21 and 22 together with the second slat groups 21 and 22. As a result, when one end of the first and second slat groups 21 and 22 approaches or abuts, light leakage from the window of the concave corner portion 61 of the room can be reduced or prevented.

(1-2) In the case where the horizontal blind 10 is provided so as to sandwich the convex corner 66 of the room As shown in FIG. 5A, when the corner of the room is convex, the first mounting frame 11 is a room It is attached to the ceiling 15 along the wall surface 67 (one wall surface) extending in the longitudinal direction of the two wall surfaces 67 and 68 sandwiching the convex corner portion 66 of the above. At this time, the first mounting frame 11, the fixing frame 41, and the pulley cover 52 are attached to the ceiling 15 so that the fixing frame 41 is positioned between the first mounting frame 11 and the wall surface 67 extending in the vertical direction. Further, the second mounting frame 12 is mounted on the ceiling 15 along the wall surface 68 (the other wall surface) extending in the lateral direction among the two wall surfaces 67 and 68 sandwiching the convex corner portion 66 of the room. At this time, the second mounting frame 12, the fixing frame 41, and the pulley cover 52 are attached to the ceiling 15 so that the fixing frame 41 is positioned between the second mounting frame 12 and the wall surface 68 extending in the lateral direction. Thereby, one end of the second mounting frame 12 and one end of the first mounting frame 11 are positioned relatively close, and the other end of the second mounting frame 12 and the other end of the first mounting frame 11 are separated. . Although not shown, windows approaching the convex corner 66 or windows connected by the convex corner 66 are respectively provided below the two wall surfaces 67 and 68 sandwiching the convex corner 66.

  In order to prevent light leakage from the window of the convex corner portion 66, first, the operation member 19 (FIG. 3) for raising and lowering and tilting provided on the front surface of the first mounting frame 11 is operated to After raising each slat 21a 21 and lowering it to the lowermost stage, the front-rear moving operation member 51 (FIG. 3) provided on the front surface of the first mounting frame 11 is operated. The back-and-forth moving pulley 46 (FIG. 5 (a)) is rotated by the operation of the back and forth moving operation member 51, and this rotational force is, as shown in FIG. 1 and FIG. The transmission side worm wheel 54, the transmission shaft 47, the pair of transmission side worms 56, 56, and the pair of male screw side worm wheels 57, 57 transmit the pair of male screwed shafts 49, 49 to the pair of male screwed shafts 49. , 49 move, the pair of boss members 48, 48 move together with the first mounting frame 11 in the direction of the broken arrow in FIG. 5B, ie, in the direction (backward) approaching the wall surface 67 extending in the longitudinal direction.

  Next, the raising and lowering tilt operation member provided on the front surface of the second mounting frame 12 is operated to raise each slat 22a of the second slat group 22 and lower it to the lowermost position, and then the second mounting frame 12 The user operates the back and forth movement operation member provided on the front of the camera. In the same manner as described above, the back-and-forth moving pulley 46 (FIG. 5A) is rotated by the operation of the back-and-forth moving operation member, and this rotational force corresponds to the pulley shaft, pulley side worm, transmission side worm wheel, transmission shaft, pair Is transmitted to the pair of externally threaded shafts via the transmission side worm and the pair of externally threaded worm wheels, and when the pair of externally threaded shafts are rotated, the pair of boss members together with the second mounting frame 12 are shown in FIG. Moving in the direction of the dashed dotted line arrow, that is, in the direction approaching (backward) the laterally extending wall surface 68. As a result, the ends of the first and second mounting frames 11 and 12 approach each other, and the ends of the first and second slats 21 and 22 approach or abut each other, so that the convex corner 66 of the room Can be closed by the first and second slats 21 and 22. Accordingly, light leakage from the windows of the convex corner 66 of the room can be reduced or prevented. The function of the horizontal blind 10 mounted and used in this manner is the same as in the case (1) where the horizontal blind 10 is provided so as to sandwich the concave corner portion 61 of the room, and therefore repeated. Description of is omitted.

It is a stick. Except for the above, the configuration is the same as that of the first embodiment.

The mounting method, use method and operation of the horizontal blind 80 configured as described above will be described.
(2-1) When the horizontal blind 80 is provided so as to sandwich the concave corner 61 of the room As shown in FIG. 10A, when the corner of the room is concave, the first mounting frame 81 is concave of the room It is attached to the ceiling 15 along the wall surface 62 (one wall surface) extending in the lateral direction of 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 attached is away from the concave corner 61 and the other end to which the attracted member 94 is fitted approaches the concave corner 61. The first attachment frame 81 is attached to 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 longitudinal direction of 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 attached is away from the concave corner portion 61, and the other end to which the attracted member 94 is fitted approaches the concave corner portion 61. Then, the second mounting frame 82 is attached to the ceiling 15. Thereby, the other end of the second mounting frame 82 and the other end of the first mounting frame 81 are positioned relatively close, and one end of the second mounting frame 82 and one end of the first mounting frame 81 are separated . Although not shown, windows approaching the concave corner 61 or windows connected by the concave corner 61 are respectively provided below the two wall surfaces 62 and 63 sandwiching the concave corner 61.

  In order to prevent light leakage from the window of the concave corner portion 61, first, as shown in FIG. 10A, by operating the lifting cord 99 suspended from the front right portion of the first mounting frame 81. By lowering the respective slats 21a of the first bottom rail 31 and the first slat group 21 to the lowermost position and operating the tilting operation rod 101 rotatably mounted on the front right portion of the first mounting frame 81, After raising each slat 21 a of the first slat group 21, the turning operation rod 104 provided on the front left side of the first mounting frame 81 is pulled toward the front. The first mounting frame 81 has a wall surface 62 extending in the direction indicated by the broken line arrow in FIG. 10B centering on the support shaft 91, that is, the other end of the first mounting frame 81 extends in the lateral direction. The member 94 is rotated in the direction away from the front (forward), and the attracted member 94 fitted near the other end of the first mounting frame 81 abuts on the indoor-side attracting member 97 and stops. At this time, the projection 98 provided on the lower surface of the movable piece 93 b of the slide rail 93 moves in a direction orthogonal to the wall surface 62 extending in the lateral direction, while the first mounting frame 81 centers on the support shaft 91. The amount of displacement caused by the circular motion is absorbed by the projection 98 moving in the longitudinal direction in the long hole 94a (FIGS. 7 and 8). As a result, the first mounting frame 81 smoothly rotates about the support shaft 92. Further, since the attracted member 94 is attracted to the indoor attraction member 97 by the magnetic force, the first attachment frame 81 does not rotate in a direction to approach the wall surface 62 unintentionally.

  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 lifting cord 99 suspended from the front left portion of the second mounting frame 82. After raising each slat 22a of the second slat group 22 by raising the slats 22a of the second slat group 22 by lowering the lowermost position to the lowest position and operating the tilting operation rod 101 rotatably attached to the front left portion of the second mounting frame 82, The turning operation rod 104 provided on the front right side of the mounting frame 82 is pulled toward the front. By the operation of the rotation operation rod 104, the second mounting frame 82 is a wall surface extending in the direction shown by the dashed dotted line arrow in FIG. 10B centering on the support shaft 92, that is, the other end of the second mounting frame 82 is longitudinal. The member 94 rotates in the direction (forward) away from the side 63, and the member 94 to be attracted fitted near the other end of the second mounting frame 82 abuts on the indoor-side attraction member 97 and stops. At this time, the projection provided on the lower surface of the movable piece of the slide rail 93 moves in a direction orthogonal to the wall surface 63 extending in the longitudinal direction, while the second mounting frame 82 performs circular movement about the support shaft 91 The amount of displacement caused by the movement is absorbed by the projection moving in the longitudinal direction in the long hole. As a result, the second mounting frame 82 smoothly rotates about the support shaft 91. Further, since the attracted member 94 is attracted to the indoor attraction member 97 by the magnetic force, the second mounting frame 82 does not rotate in a direction to approach the wall surface 63 unintentionally. 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 each other, so that the concave corner portion of the room The gap 61 can be closed by the first and second slat groups 21 and 22. Accordingly, light leakage from the window of the concave corner 61 of the room can be reduced or prevented.

  The operation of the horizontal blind 80 so mounted and used will now be described. Because the first and second slat groups 21 and 22 hardly move in the longitudinal direction, that is, the distance between the side edges of the first and second slat groups 21 and 22 and the concave corner 61 of the room hardly changes. The light leakage can be maintained without changing from the side edge of the first and second slat groups 21 and 22 opposite to the concave corner 61. Further, since the horizontal lengths of the first and second slat groups 21 and 22 are respectively formed longer than the lengths of the first and second attachment frames 81 and 82, the first and second attachment frames 81 and 82 Even if the other ends of the first and second mounting frames 81, 82 are separated from the wall surfaces 62, 63 together with the other ends of the first and second slat groups 21, 22 by rotating around one end of the And the 2nd attachment frames 11 and 12 do not contact. As a result, when one end of the first and second slat groups 21 and 22 approaches or abuts, light leakage from the window of the concave corner portion 61 of the room can be reduced or prevented. Furthermore, 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 Even if the other ends of the first and second mounting frames 81, 82 are separated from the wall surfaces 62, 63 together with the other ends of the first and second slat groups 21 and 22 by rotating around one end respectively, the first bottom The rails 31 and the second bottom rails do not contact with each other. As a result, when one end of the first and second slat groups 21 and 22 approaches or abuts, 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 66 of the room As shown in FIG. 11A, when the corner of the room is convex, the first mounting frame 81 is a room It is attached to the ceiling 15 along the wall surface 67 (one wall surface) extending in the longitudinal direction of 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 attached is away from the convex corner 66, and the other end to which the attracted member 94 is fitted approaches the convex corner 66 In this state, the first mounting frame 81 is mounted on the ceiling 15. The second mounting frame 82 is mounted on the ceiling along the wall surface 68 (the other wall surface) extending in the lateral direction of the two wall surfaces 67 and 68 sandwiching the convex corner 66 of the room. At this time, one end of the second mounting frame 82 to which the support stay 92 is attached is away from the convex corner 66, and the other end to which the attracted member 94 is fitted approaches the convex corner 66 In this state, the second mounting frame 82 is mounted on the ceiling. Thereby, the other end of the second mounting frame 82 and the other end of the first mounting frame 81 are positioned relatively close, and one end of the second mounting frame 82 and one end of the first mounting frame 81 are separated . Although not shown, windows approaching the convex corner 66 or windows connected by the convex corner 66 are respectively provided below the two wall surfaces 67 and 68 sandwiching the convex corner 66.

  In order to prevent light leakage from the window of the convex corner portion 66, first, as shown in FIG. 11A, the raising and lowering cord 99 suspended from the front right portion of the first mounting frame 81 is operated. Thus, the slats 21a of the first bottom rail 31 and the first slat group 21 are lowered to the lowermost position, and the tilting operation rod 101 rotatably mounted on the front right portion of the first mounting frame 81 is operated. After the slats 21a of the first slat group 21 are erected, the rotary operation rod 104 provided on the front left side of the first mounting frame 81 is pushed toward the wall surface 67 extending in the longitudinal direction. The first mounting frame 81 is a wall surface 67 extending in the direction indicated by the broken line arrow in FIG. 11B centering on the support shaft 91, that is, the other end of the first mounting frame 81 extends in the longitudinal direction. The member to be attracted 94 fitted in the vicinity of the other end of the first mounting frame 81 abuts against the wall-side attraction member 96 and stops. At this time, the projection 98 provided on the lower surface of the movable piece 93 b of the slide rail 93 moves in a direction orthogonal to the wall surface 67 extending in the longitudinal direction, while the first mounting frame 81 centers on the support shaft 91. The amount of displacement caused by the circular motion is absorbed by the projection 98 moving in the longitudinal direction in the long hole 94a (FIGS. 7 and 8). As a result, the first mounting frame 81 smoothly rotates about the support shaft 91. Further, since the attracted member 94 is attracted to the wall-side attracting member 96 by the magnetic force, the first mounting frame 81 does not rotate in a direction away from the wall surface 67 unintentionally.

  Next, as shown in FIG. 11A, the slats 22a of the second bottom rail and the first slat group 22 are operated by operating the lifting cord 99 suspended from the front left portion of the second mounting frame 82. After raising the slats 22a of the second slat group 22 by raising the slats 22a of the second slat group 22 by lowering to the lowermost position and operating the tilt operation rod 101 rotatably attached to the front left portion of the second mounting frame 82, (2) The rotary operation rod 104 provided on the front right side of the mounting frame 82 is pushed toward the laterally extending wall surface 68. By the operation of the rotation operation rod 104, the second mounting frame 82 is a wall surface extending in the direction indicated by the dashed dotted line arrow in FIG. 11B around the supporting shaft 91, that is, the other end of the second mounting frame 82 is transversely The member 94 rotates in a direction (backward) approaching 68, and the member 94 to be attracted, which is fitted in the vicinity of the other end of the second mounting frame 82, abuts on the wall side attraction member 96 and stops. At this time, the projection provided on the lower surface of the movable piece of the slide rail 93 moves in a direction orthogonal to the wall surface 68 extending in the lateral direction, while the second mounting frame 82 performs circular movement about the support shaft 91 The amount of displacement caused by the movement is absorbed by the projection moving in the longitudinal direction in the long hole. As a result, the second mounting frame 82 smoothly rotates about the support shaft 91. Further, since the attracted member 94 is attracted to the wall-side attracting member 96 by the magnetic force, the second mounting frame 82 does not rotate in a direction away from the wall surface 68 unintentionally. 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 each other. The gap of the portion 66 can be closed by the first and second slat groups 21 and 22. Accordingly, light leakage from the windows of the convex corner 66 of the room can be reduced or prevented. The action of the horizontal blind 80 attached and used in this manner is the same as in the case of (2-1) “when the horizontal blind 80 is provided so as to sandwich the concave corner portion 61 of the room” in the above (2-1).
