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 specifically, the gap between the adjacent shields is changed by changing the polymerization length in a state where the adjacent shields of the first shield unit are polymerized and changing the sum of the gap amounts where light leakage occurs. The present invention relates to a solar radiation shielding device suitable for horizontally connected continuous windows for preventing light leakage from the outer side surface.

  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 addition, the shielding member is configured to move in the longitudinal direction of the support member in conjunction with the elevation of the shielding member, or to move in the longitudinal direction of the support member from the front of the lower limit position during the descent of the shielding member. Configured

  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 slat moves in the longitudinal direction after falling to the lower limit position, the gap between adjacent slats is constant from the time the slat moves up to the upper limit position to the time it descends to the lower limit position, and the slats After lowering to the lower limit position, by sliding the rotating shaft and the shielding material lifting device in the longitudinal direction, the slats move in the adjacent slat direction, and the gap between the adjacent slats is closed. Furthermore, 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, adjacent head boxes 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. (See, for example, FIGS. 13 and 15 of Patent Document 2). 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. Further, when the shield and the band-shaped shield are formed in a honeycomb shape, a cut is formed with a predetermined length on the base end side of the band-shaped shield material, and a long hole is formed on the joint piece in a state formed in a honeycomb shape. The elevating cord is inserted into the long hole. Furthermore, a weight member is provided at the lower edge of the shielding material.

  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.

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. Further, in the shielding device shown in FIG. 2, FIG. 3 and FIG. 7 of the conventional Patent Document 2 described above, when the thickness of the weight member is relatively thick, a gap is generated in the overlapping portion of the shielding material.

In the longitudinal direction, the adjacent bottom rails do not come in contact with each other even if they extend or contract in the longitudinal direction. As a result, the first shield unit can be reliably reduced to a predetermined length. When one lifting cord is inserted in a band-shaped shield without a weight member dedicated to the band-shaped shield, when the band-shaped shield moves in a lateral direction when the band-shaped shield is pulled with a string or the like, As compared with the shielding device shown in FIGS. 13 and 15 of the prior art Patent Document 2 in which the strip-shaped shielding material is stuck to the shielding material and can not move smoothly depending on the position of the shielding material, the present invention The polymerization length of the matching shield can be changed smoothly.

Or by extending both in the longitudinal direction, the gap between the end faces facing each other of the first shield unit and another second shield unit etc. is narrowed, or the ends facing each other are polymerized. Therefore, the contact between the first shield unit and another second shield unit can be prevented. As a result, damage to the first shield unit, another second shield unit, and the like can be prevented.

  In the solar radiation shielding apparatus according to the eighth aspect of the present invention, since one or both of the first shielding unit and the other second shielding unit are configured to be unable to move up and down except in the initial state, By extending either or both of the first shielding unit and the other second shielding unit in the longitudinal direction, the gap between the opposing end surfaces of the first shielding unit and the other second shielding unit can be obtained. When narrowed, the first shield unit or another second shield unit which has not been extended can be raised and lowered alone. As a result, the operability of the first shield unit or another second shield unit which has not been extended can be kept good, and between the first shield unit and the other second shield unit Light leakage can be reduced. Furthermore, when opposing ends of the first shield unit and another second shield unit polymerize, it is not possible to lift and lower both the first shield unit and the other second shield unit. The contact between the first shield unit and another second shield unit can be prevented, and damage to the first shield unit and another second shield unit can be prevented, and the second shield unit and another second shield unit can be prevented. It is possible to prevent light leakage with the shield unit.

As a result, the contact between the first shield unit and another shield can be prevented, so that damage to the first shield unit or another shield can be prevented, and the first shield unit and another shield can be prevented. Light leakage can be prevented.

  In the solar radiation shielding apparatus according to the tenth aspect of the present invention, when the lower end of one or both of the first shielding unit and the other second shielding unit reaches the lower limit position or at a position close to the lower limit , Or one or both of the first shield unit and another second shield unit extend in the longitudinal direction, so that either the first shield unit or another second shield unit etc. The operation of extending the first shield unit or another second shield unit in the longitudinal direction is prohibited in a state where one or both are lowered halfway. As a result, with either or both of the first shielding unit and the other second shielding unit being lowered halfway, either one or both of the first shielding unit or the other second shielding unit can be After the longitudinal extension, the troublesome operation of reducing the longitudinal direction again can be avoided. In addition, it is possible to prevent the shield and the bottom rail of the first shield unit from falling while contacting another second shield unit and the like adjacent to the first shield unit. Furthermore, it is possible to prevent the lowering of a shield such as another second shield unit or the bottom rail while coming into contact with the first shield unit or the like adjacent to the other second shield unit or the like.

  In the solar radiation shielding apparatus according to the eleventh aspect of the present invention, at least two sets of shields of the first shield unit are at least two sets of slats of the first slat group unit, and are adjacent to each other among at least two sets of slats. Since a part of the longitudinal direction of each slat of the matching slat group is alternately polymerized, it is possible to change the total amount of the gap in which the light leakage occurs, without using the auxiliary strip shield, the first It is possible to prevent the light leakage from the gap between adjacent slat groups of the slat group unit and the outer surface of the first slat group unit. In addition, even if the first slat group unit is extended or contracted, the adjacent slat groups of the first slat group unit are kept apart without being separated in the longitudinal direction, and light is leaked from between the adjacent slat groups. You can prevent Furthermore, in the case where the first slat group unit is suspended from one set of mounting frames and the window is a continuous window extending in the horizontal direction, both ends of the first slat group unit are respectively longitudinal from the both ends of the mounting frame Since the first slat group unit is provided so as to protrude in the longitudinal direction of the second slat group unit or the like separate from the first slat group unit, the first slat group unit is extended in the longitudinal direction. The attachment frame does not extend in the longitudinal direction even if a part is polymerized to a part of another second slat group unit or the like. As a result, it is possible to prevent the attachment frame for hanging the first slat group unit from coming into contact with the attachment frame for hanging another second slat group unit and the like. On the other hand, in the case where the first slat group unit is suspended from the first frame unit and the window is a continuous window extending in the horizontal direction, both ends of the first slat group unit extend in the longitudinal direction from both ends of the first frame unit. Since they are configured to project respectively, they are provided adjacent to each other in the longitudinal direction of the second slat group unit etc. which is different from the first slat group unit, and the first frame unit is extended to form a part of the first slat group unit Even when overlapping with a part of another second slat group unit or the like, the attachment frame of the first frame unit can be prevented from contacting the attachment frame of another second frame unit or the like.

  In the solar radiation shielding apparatus according to the twelfth aspect of the present invention, the first slat group unit and the other second slat group unit are extended in the longitudinal direction to form the first slat group unit and another second slat group unit. Since the gap between the end faces opposing each other with the two slat group unit etc. is narrowed or the end parts facing each other are superposed, when the gap between the end faces facing each other becomes narrow, the first slat The light leakage between the group unit and another second slat group unit can be reduced, and when the opposing ends of the first slat group unit and another second slat group unit polymerize, the first slat Light leakage between a group unit and another second slat group unit or the like can be prevented.

Thus, the first slat group unit or another second slat group unit that has not been extended when the gap between the opposing end faces of the first slat group unit and the other second slat group unit is narrowed. The slat group unit can be raised and lowered or tilted or raised and lowered independently. As a result, the operability of the first slat group unit or another second slat group unit which has not been extended can be maintained well, and between the first slat group unit and another second slat group unit Light leakage can be reduced. In addition, when opposite ends of the first slat group unit and another second slat group unit polymerize, lifting and tilting of both the first slat group unit and the other second slat group unit becomes impossible. . As a result, the contact between the first slat group unit and another second slat group unit can be prevented, and damage to the first slat group unit and another second slat group unit can be prevented. Light leakage with the second slat group unit can be prevented.

  In the solar radiation shielding apparatus according to the fourteenth aspect of the present invention, since the first slat group unit and the other slat group are configured to disable elevation / tilt or elevation / tilt excluding the initial state, respectively, the first slat When the group unit is extended or reduced in the longitudinal direction and the first slat group unit is in a state other than the most contracted state, the first slat group unit and another slat group can not be moved up and down. As a result, since the contact between the first slat group unit and another slat group can be prevented, damage to the first slat group unit and another slat group can be prevented and the first slat group unit and another slat group Light leakage can be prevented.

  In the solar radiation shielding apparatus according to the fifteenth aspect of the present invention, each slat of either one or both of the first slat group unit and the other second slat group unit is adjusted to an angle with the least light leakage, By configuring either or both of the first slat group unit or another second slat group unit to extend in the longitudinal direction thereof, the first slat group unit can be extended after the first slat group unit is extended. In the state where it is polymerized in the second slat group unit and the like, the angle at which the light leakage is already at the smallest level can prevent contact between slats due to the change of the tilt angle of the first slat group unit. In addition, since another second slat group unit is in the state of being polymerized to the first slat group unit after the extension of another second slat group unit, the second slat group unit is already at the smallest angle of light leakage, and thus another second slat group unit. It is possible to prevent contact between slats due to the change in tilt angle of the group unit.

(Not shown). The left and right polymerization tilting drums are rotatably mounted on the mounting frame 11 in a polymerization drum holder (not shown) provided in the mounting frame 11. Then, when the elevating tilt drive shaft 17 rotates forward or backward by an angle less than 90 degrees, the polymerization tilt drum rotates with the elevating tilt drive shaft 17, and the polymerization ladder cords 31, 32 also rotate. It is configured to rotate integrally with it.

Configured

  On the other hand, the slat group 13 on the right is lifted and lowered by the two non-polymerizing lifting cords 21 among the four non-polymerizing lifting cords 21 and 22, and the left two non-polymerizing lifting cords 22 to the left Slat group 14 is configured to move up and down (FIG. 1).

In addition, the code | symbol 34 in FIG. 1 is the operation member for raising / lowering tilting attached to the front right part of the attachment frame 11 of 1 set. The raising and lowering tilt operating member 34 is connected to the raising and lowering tilt drive shaft 17 via a pulley and gears (not shown) in order to simultaneously raise and lower or tilt the plurality of slats 13a and 14a of the two sets of slats 13 and 14 simultaneously. . Then, by operating the elevation / tilt operation member 34, the single elevation / tilt / tilt drive shaft 17 is rotated, and the non-polymerization elevation cords 21 and 22 are wound around the non-polymerization winding drum 19 or non-polymerization. By being fed out from the winding drum 19 for polymerization, the two sets of slat groups 13 and 14 can be moved up and down simultaneously, and the back and forth movement of the non-polymerization ladder cords 23 and 24 and the polymerization ladder cords 31 and 32 move up and down. The tilt angles of the slats 13a and 14a can be changed simultaneously by tilting the plurality of slats 13a and 14a of the two sets of slat groups 13 and 14 forward or backward.

  On the other hand, in one set of mounting frames 11, telescopic mechanisms 35, 36 are provided for changing the polymerization length in a state where two adjacent sets of slat groups 13, 14 are polymerized (FIG. 1). As shown in detail in FIGS. 2 to 5, these extension mechanisms 35, 36 include an extension drive shaft 37 provided in the mounting frame 11 so as to extend in the longitudinal direction thereof, and four of the extension drive shafts 37. Four male screw members 38 and 39 respectively fitted at positions facing the non-polymerization drum holder 18, and two positions fitted opposite to the two polymerization drum holders of the extension drive shaft 37 Two externally threaded members (not shown), four internally threaded portions 41 and 42 provided on the four non-polymerization drum holders 18 and capable of being screwed onto the four externally threaded members 38 and 39; Two female screw parts (not shown) provided on the polymerization drum holder and screwed to the above two male screw members, and a telescopic operating member 43 connected to the telescopic drive shaft 37 via a gear and a pulley (not shown) And. By operating the expansion and contraction operation member 43, the pulley is rotated and the expansion and contraction drive shaft 37 is rotated. Of the six male screw members 38 and 39, the three male screw members 38 on the right are right-handed, and the three male screw members 39 on the left are left-handed. Further, among the six female screw parts 41 and 42, the three female screw parts 41 on the right side are right-handed, and the three female screw parts 42 on the left side are left-handed. The telescopic drive shaft 37 and the male screw members 38, 39 are rotated by operating the telescopic operating member 43, and the female screw portions 41, 42 are moved in the axial direction of the telescopic drive shaft 37 to form two adjacent sets. The polymerization length is configured to change in a state where the slat groups 13 and 14 are polymerized.

  Reference numeral 44 in FIGS. 2 to 5 denotes a non-polymerization spacer which is interposed between the mounting frame 11 and the non-polymerization drum holder 18 and is fixed to the inner surface of the mounting frame 11. Reference numerals 46 in FIGS. 2 to 5 denote a plurality of non-polymerization balls provided between the non-polymerization spacer 44 and the non-polymerization drum holder 18. The polymerization drum holder 18 can be smoothly moved in the longitudinal direction of the mounting frame 11. Furthermore, the spacer for polymerization (not shown) having the same function as the spacer 44 for non-polymerization and the ball 46 for non-polymerization also between the mounting frame 11 and the drum holder 18 for polymerization and the ball for polymerization (not shown) ) Is provided.

  On the other hand, both ends of the first slat group unit 12 are configured to project in the longitudinal direction from both ends of the mounting frame 11 (FIGS. 1 and 6). That is, both ends of the first slat group unit 12 are configured to protrude in the longitudinal direction from both ends of the mounting frame 11 regardless of extension or reduction in the longitudinal direction of the first slat group unit 12. Also, the first bottom unit 26 is formed shorter than the first slat group unit 12. In other words, both ends of the first slat group unit 12 are configured to respectively project in the longitudinal direction from both ends of the first bottom unit 26 regardless of extension or reduction in the longitudinal direction of the first slat group unit 12 Ru. Further, the second slat group units 52 different from the first slat group unit 12 hanging down from the mounting frame 11 are adjacent in the longitudinal direction of the first slat group unit 12 with the second slat group units 52 hanging down from the other mounting frames 51 respectively. Provided (Figure 7). Another mounting frame 51 is configured the same as the mounting frame 11, and another second slat group unit 52 is configured the same as the first slat group unit 12. That is, another second slat group unit 52 has two sets of slat groups 53, 54. Furthermore, another second bottom unit 56 is provided adjacent to the first bottom unit 26 in the longitudinal direction. The other second bottom units 56 are respectively attached to the lower ends of the other second slat group units 52. Then, by extending the first slat group unit 12 in the longitudinal direction, the gap between the end faces facing each other between the first slat group unit 12 and another second slat group unit 52 is narrowed, and another second slat group is formed. By stretching the unit 52 in the longitudinal direction, the opposing ends of the first slat group unit 12 and the other second slat group unit 52 are configured to polymerize.

  The usage method and operation of the horizontal blind 10 thus configured will be described. In the case of blocking the light introduced from the window in the rectangular window frame 16, first, the raising and lowering tilt operation member 34 of the horizontal blind 10 is operated to simultaneously slat 13a and 14a of the two sets of slats 13 and 14 simultaneously. After standing up, the slats 13a and 14a of the two sets of slats 13 and 14 are simultaneously lowered, and the lower surfaces of the two sets of bottom rails 27 and 28 are brought into contact with the upper surface of the lower frame portion (not shown) of the window frame 16. Get in touch. Next, when the telescopic operating member 43 is operated, the pulleys rotate, and the telescopic drive shafts 37 rotate in the direction of the solid line arrow in FIG. 2B, and the three telescopic drive shafts 37 fitted on the right side 2 (b) in the same direction as the telescopic drive shaft 37 (the direction of the solid arrow in FIG. 2 (b)), the three female threads 41 on the right side are in the direction of the broken arrow in FIG. Move to the right. At the same time, the left three male screw members 39 fitted with the extension drive shaft 37 rotate in the same direction as the extension drive shaft 37 (in the direction of the solid line arrow in FIG. 3B). The portion 42 moves in the direction of the broken arrow in FIG. 3 (b), that is, in the left direction. Thus, the non-polymerization winding drum 19 and the non-polymerization tilting drum mounted on the two right non-polymerization drum holders 18 and the polymerization tilting drum mounted on the right one polymerization drum holder The right slat group 13 and the right bottom rail 27 move rightward to approach the inner surface of the right frame (not shown) of the window frame 16. In addition, a non-polymerization winding drum 19 and a non-polymerization tilting drum attached to the two left non-polymerization drum holders 18 and a polymerization tilting drum attached to the left one polymerization drum holder The left slat group 14 and the left bottom rail 28 move leftward to approach the inner surface of the left frame (not shown) of the window frame 16. As a result, the polymerization length of two adjacent pairs of slat groups 13 and 14 decreases, and the first slat group unit 12 elongates in the longitudinal direction, so that the total amount of gaps causing light leakage changes, Almost all of the rectangular window frame 16 is covered by the one slat group unit 12. Accordingly, it is possible to prevent the light leakage from the gap between the adjacent slat groups 13 and 14 of the first slat group unit 12 and the outer surface of the first slat group unit 12.

  On the other hand, even if the first slat group unit 12 is extended or reduced, the two adjacent slat groups 13 and 14 are kept in a polymerized state without being separated in the longitudinal direction, and thus between the adjacent slat groups 13 and 14 Light can be prevented from leaking out. Further, since the opposing end portions of the bottom rails 27 and 28 of the first bottom unit 26 are formed shorter than the slat groups 13 and 14, even if the first slat group unit 12 is reduced in the longitudinal direction, each bottom The rails 27, 28 do not touch each other. As a result, the first slat group unit 12 can be reliably reduced to a predetermined length, and generation of a gap between the slats 13a and the slats 14a in the depth direction due to the contact between the bottom rails 27, 28 can be prevented. , 14 can be suppressed or prevented. In addition, since each slat group 13, 14 of the first slat group unit 12 is suspended from the mounting frame 11 by two sets of non-polymerization ladder cords 23, 24, and one set of polymerization ladder cords 31, 32, each slat The groups 13 and 14 can be suspended in a stable state, and the polymerization length of two adjacent pairs of slat groups 13 and 14 can be smoothly changed. Further, in each slat group 13, 14, one pair of polymerization ladder cords 31, 32 is provided in the overlapping portion 33 of the adjacent slat group 13, 14, so that the first slat group unit 12 extends in the longitudinal direction or Even if the size is reduced, it is difficult for the polymerization state of a part of the adjacent slat groups 13 and 14 of the first slat group unit 12 to be released. As a result, a part of the adjacent slat groups 13 and 14 of the first slat group unit 12 is kept in a regularly polymerized state. Further, since each slat group 13, 14 of the first slat group unit 12 is moved up and down by the two non-polymerization lifting cords 21, 22, the slat groups 13, 14 can be moved up and down in a stable state, and adjacent to each other. The polymerization length of the slat groups 13 and 14 can be changed smoothly.

  On the other hand, since both ends of the first slat group unit 12 are configured to respectively project in the longitudinal direction from both ends of the mounting frame 11, when the window is a continuous window continuing in the horizontal direction, it is different from the first slat group unit 12 Is provided adjacent to the second slat group unit 52 in the longitudinal direction to extend the first slat group unit 12 in the longitudinal direction, and a part of the first slat group unit 12 in the longitudinal direction to another second slat group unit 52 The mounting frame 11 does not extend in the longitudinal direction even if it is polymerized in a part of the longitudinal direction of the frame. As a result, it is possible to prevent the mounting frame 11 which hangs the first slat group unit 12 from coming into contact with the mounting frame 11 which hangs the other second slat group unit 52. The second slat group unit 52 separate from the first slat group unit 12 suspended from the mounting frame 11 is adjacent to the first slat group unit 12 in the longitudinal direction in a state of hanging down from another mounting frame 51. In the case where the window is a continuous window extending in the horizontal direction, the entire continuous window can be covered by the first slat group unit 12 and the second slat group unit 52.

  In addition, when the first slat group unit 12 is extended in the longitudinal direction, the gap between the end faces facing each other between the first slat group unit 12 and another second slat group unit 52 becomes narrow, so that extension is still performed in this state. The other second slat group unit 52 can be moved up and down or tilted up and down and tilted. As a result, light leakage from the gap can be reduced, and the operability of the other second slat group unit 52 can be well maintained. Then, when the other second slat group unit 52 is extended in the longitudinal direction, the opposing ends of the first slat group unit 12 and the other second slat group unit 52 polymerize, so that the first slat group unit is extended. It is possible to prevent light leakage from between 12 and another second slat group unit 52. Furthermore, since the first bottom unit 26 is formed shorter than the first slat group unit 12, even if the first slat group unit 12 is extended or contracted in the longitudinal direction, the first bottom unit 26 is another second bottom unit 56. There is no contact with As a result, the first slat group unit 12 can be reliably extended to a predetermined length, and the generation of a gap in the depth direction between the slat 14a and the slat 53a due to the contact between the first bottom unit 26 and the second bottom unit rail 56 is prevented. It is possible to suppress or prevent light leakage from the polymerized slat group 14, 53.

Second Embodiment
FIG. 8 shows a second embodiment of the present invention. In FIG. 8, the same reference numerals as in FIG. 7 denote the same parts. In this embodiment, of the two sets of polymerization ladder cords 61 and 62, the polymerization ladder cord 61 on the left side extends in the vertical direction along the front edge and the rear edge of the plurality of slats 13a of the slat group 13 on the right side. A pair of polymerization longitudinal cords 61a, 61a, and a pair of polymerization horizontal cords, the ends of which are fixed to the polymerization longitudinal cords 61a, 61a and hold the slats 13a and slats 13b from their upper and lower surfaces. And 61b. Further, of the two sets of polymerization ladder cords 61 and 62, the polymerization ladder cord 62 on the right side is a pair of polymerization ladders extending vertically along the front edge and the rear edge of the plurality of slats 14a of the left slat group 14. Vertical cords 62a and 62a, and a pair of polymerization horizontal cords 62b, both ends of which are fixed to the polymerization use vertical cords 62a and 62a, hold each slat 14a from the upper surface and the lower surface and hold it at a predetermined position. Except for the above, the configuration is the same as that of the first embodiment.

  On the other hand, two tilt shafts 112 and 113 are respectively inserted into the two sets of mounting frames 102 and 103 on the same axis (FIG. 11). Then, hexagonal prism-shaped male shafts 114 and hexagonal cylindrical female shafts 116 are respectively provided at opposite ends of the tilt shafts 112 and 113. The male shaft 114 is movable relative to the female shaft 116 in the longitudinal direction and is rotatably inserted integrally in the circumferential direction. The end of the right tilt shaft 112 of the two tilt shafts 112 and 113 is connected to the elevation / tilting operation member 34 and the knob 43 via a universal joint (not shown). Furthermore, two tilting drums (not shown) are respectively fitted to the tilt shafts 112 and 113, and a pair of non-overlapping vertical cords 23a of the non-overlapping ladder cords 23 and 24 are fitted to these tilting drums. 24a are attached respectively. The two tilt shafts 112 and 113 are simultaneously pivoted by pivoting the elevation / tilting operation member 34 so that the tilt angles of the two sets of slats 13 and 14 can be simultaneously changed. There is.

  As in the first embodiment, a part of each slat 13a, 14a of two adjacent pairs of slat groups 13, 14 is configured to alternately polymerize. When the first frame unit 101 extends or contracts in the longitudinal direction, the polymerization length changes in a state where the adjacent slat groups 13 and 14 are polymerized, and the first slat group unit 12 extends in the longitudinal direction. It is configured to expand or contract. Reference numeral 118 in FIG. 10 is a control rod attached at the base end to the right mounting frame 102 and gripped to move the right mounting frame 102 in the longitudinal direction, and reference numeral 119 is the left mounting frame 103. The base end is attached to the control rod and is gripped to move the left mounting frame 103 in the longitudinal direction.

  On the other hand, both ends of the first slat group unit 12 are configured to respectively project in the longitudinal direction from both ends of the first frame unit 101 (FIGS. 10 to 12). That is, both ends of the first slat group unit 12 are configured to respectively project in the longitudinal direction from both ends of the first frame unit 101 regardless of extension or reduction in the longitudinal direction of the first slat group unit 12. . In addition, a second slat group unit 52 different from the first slat group unit 12 hanging down from the first frame unit 101 was hung down from two sets of mounting frames 122 and 123 of another second frame unit 121, respectively. In the state, it is provided adjacent to the first slat group unit 12 in the longitudinal direction (FIG. 12). Another second frame unit 121 is configured the same as the first frame unit 101. Except for the above, the configuration is the same as that of the first embodiment.

  The usage method and operation of the thus configured horizontal blind 100 will be described. In the case of shielding the light introduced from the window in the rectangular window frame 16, first, the elevating and tilting operation member 34 of the horizontal blind 100 and the knob 43 are operated to slat 13a, At the same time, the lower surfaces 14a of the two bottom rails 27 and 28 are brought into contact with the upper surface of the lower frame (not shown) of the window frame 16. Next, the elevating and lowering operation member 34 is turned to raise the slats 13a and 14a of the two sets of slats 13 and 14 simultaneously. Further, the right operating rod 118 is operated in the right direction to move the right mounting frame 102 to the right frame portion (not shown) of the window frame 16 and the left operating rod 119 is operated in the left direction. The mounting frame 103 is brought close to the inner surface of the left frame (not shown) of the window frame 16. As a result, when the first frame unit 101 extends in the longitudinal direction, the polymerization length of the adjacent slat groups 13 and 14 decreases, and the first slat group unit 12 extends in the longitudinal direction. The sum of the generated gap amounts changes, and the first slat group unit 12 covers almost all of the rectangular window frame 16. Therefore, similarly to the first embodiment, it is possible to prevent the light leakage from the gap between the adjacent slat groups 13 and 14 of the first slat group unit 12 and the outer surface of the first slat group unit 12.

  On the other hand, even if the first frame unit 101 is extended or reduced, the adjacent slat groups 13 and 14 of the first slat group unit 12 are kept in a polymerized state without being separated in the longitudinal direction. , 14 can be prevented from leaking light. Further, since the slide connection mechanism 104 is provided with a stopper that regulates the amount of extension and reduction in the longitudinal direction of the two sets of slat groups 13 and 14, even if the first slat group unit 12 extends in the longitudinal direction, The first frame unit 101 does not extend to such a length that part of the two slat groups 13 and 14 adjacent to each other is released from polymerization. As a result, it is possible to reliably keep part of two adjacent sets of slat groups 13 and 14 in a polymerized state. Further, since both ends of the first slat group unit 12 are configured to respectively project in the longitudinal direction from both ends of the first frame unit 101, when the window is a continuous window connected in the horizontal direction, the first slat group unit 12 and Is provided longitudinally adjacent to another second slat group unit 52, and the first slat group unit 12 is extended in the longitudinal direction to bring the first slat group unit 12 closer to another second slat group unit 52. Later, when another second slat group unit 52 is extended in the longitudinal direction to polymerize a part of the first slat group unit 12 to a part of the other second slat group unit 52, the first frame unit 101 and Although the other second frame unit 121 also extends longitudinally, the first frame unit 101 is shorter than the first slat group unit 12 and another Since the two-frame unit 121 is shorter than another second slat group unit 52, the first frame unit 101 hanging the first slat group unit 12 drops to the second frame unit 121 hanging the other second slat group unit 52. Contact can be prevented. Furthermore, the second slat group unit 52 different from the first slat group unit 12 suspended from the first frame unit 101 is suspended from the other second frame unit 121 in the longitudinal direction of the first slat group unit 12. Since they are provided adjacent to each other in the direction, when the window is a continuous window extending in the horizontal direction, the entire continuous window can be covered by the first slat group unit 12 and the second slat group unit 52. The usage method and operation other than those described above, and the functions and effects are substantially the same as those in the first embodiment, and thus the repetitive description will be omitted.

The control procedure to move to is stored. That is, when the lower end of the first slat group unit 12 has not reached the lower limit position, the first memory 174 stores a prohibited item in which the first slat group unit 12 can not be extended in the longitudinal direction.

That is, when the slats 13a and 14a of the two slat groups 13 and 14 of the first slat group unit 12 are not adjusted to an angle with the least light leakage, a prohibited item in which the first slat group unit 12 can not be extended is It is stored in the first memory 174.

When shielding the light introduced from the continuous window in the horizontal window frame 16, first, using the first remote control or the first operation switch for the first slat group unit 12, each slat 13 a of the first slat group unit 12, If the operation of simultaneously raising 14 a and simultaneously lowering the first slat group unit 12 is performed, the elevating and tilting motor is activated. Then, the tilt angle of each slat 13a, 14a reaches the fully closed limit position, the fully closed limit switch 167 for the tilt angle is turned on, and the fully closed stop signal is input to the first controller 173 for the first slat group unit 12. Then, the first controller 173 stops the fully closed rotation of the tilt angle by the raising and lowering / tilting motor 164. When the first bottom unit 26 reaches the lower limit position and the lower limit switch 166 is turned on and the descent stop signal is input to the first controller 173, the first controller 173 stops the motor 164 for raising / lowering and tilting. The descent of the slat group unit 12 is stopped (FIG. 15 (a)).

  When the tilt angle fully closed limit switch 167 is turned on, the lower limit switch 166 is turned on, and there is no stop signal from the remote control or the operation switch, the first slat group unit 12 is moved backward, and the back and forth movement motor 146a to start. As a result, the rotational force of the back and forth movement motor 146a is transmitted to the back and forth movement lead screw member 146e through the rotation transmission shaft 146g, the worm 146h and the worm wheel 146i, and rotation of the back and forth movement lead screw member 146e The slider 146b moves in the direction of the dashed arrow in FIG. 14 (b). Then, when the first slat group unit 12 reaches the rear limit position and the rear limit switch 170 is turned on and the rear movement stop signal is input to the first controller 173, the first controller 173 stops the back and forth movement motor 146a. Then, the backward movement of the first slat group unit 12 is stopped.

  When the rear limit switch 170 is turned on and there is no stop signal of the first remote controller or the first operation switch, the extension motor 147a for extending the first slat group unit 12 is activated. Thus, the rotational force of the extension motor 147a is transmitted to the extension lead screw member 147b, and the extension sliders 147c and 147d move away from each other due to the rotation of the extension lead screw member 147b. Then, when the first slat group unit 12 reaches the extension limit position and the extension limit switch 171 is turned on and the extension stop signal is input to the first controller 173, the first controller 173 extends the first slat group unit 12. Stop. Here, when the first slat group unit 12 starts to extend in its longitudinal direction, the first controller 173 causes the first slat group unit 12 to contract in the longitudinal direction based on the detection outputs of the limit switches 165 to 172. It is detected that it is in a state other than the most contracted state (initial state), and elevation and tilt of the first slat group unit 12 are prohibited (disabled). At this time, since the gap between the end faces facing each other between the first slat group unit 12 and another second slat group unit 52 becomes narrow, light leakage from this gap can be reduced, and another second slat group unit 52 can be reduced. Can be raised and lowered, and the operability of the other second slat group unit 52 can be kept good.

  On the other hand, when the operation for extending the second slat group unit 52 is performed by the second remote controller or the second operation switch for the second slat group unit 51, the extension motor is activated in the same manner as described above. Thus, the rotational force of the extension motor is transmitted to the extension lead screw member in the same manner as described above, and the extension sliders move away from each other due to the rotation of the extension lead screw member. Then, when the second slat group unit 52 reaches the extension limit position and the extension limit switch is turned on and the extension stop signal is input to the second controller for the second slat group unit 52, the second controller receives the second slat The extension of the group unit 52 is stopped (FIG. 15 (b)). Here, when the second slat group unit 52 starts to extend in the longitudinal direction, the second controller reduces the second slat group unit 52 in the longitudinal direction based on the detection output of each limit switch. The second slat group unit 52 is inhibited from moving up and down and tilting upon detection of a state other than the (initial state). As a result, the opposite ends of the first slat group unit 12 and another second slat group unit 52 polymerize, so that light leakage between the first slat group unit 12 and another second slat group unit 52 is reduced. Since it can prevent and contact with the 1st slat group unit 12 and another 2nd slat group unit 52 can be prevented, damage to the 1st slat group unit 12 or another 2nd slat group unit 52 can be prevented.

  Although the polymerization length of the adjacent slat groups 13 and 14 of the first slat group unit 12 becomes smaller and the polymerization length of the adjacent slat groups 53 and 54 of the second slat group unit 52 becomes smaller by the above operation, , And a part of the first slat group unit 12 and a part of the second slat group unit 52 polymerize. As a result, the sum of the gap amounts where light leakage occurs changes, and almost all of the horizontally long continuous windows are covered by the first and second slat group units 12 and 52. That is, the gap between the adjacent slat groups 13 and 14 of the first slat group unit 12, the gap between the outer surface of the first slat group unit 12 and the right frame portion of the window frame 16, and the second slat group unit 52 Since the gap between the slat groups 53 and 54 to be fitted and the gap between the outer surface of the second slat group unit 52 and the left frame portion of the window frame 16 are closed, light leakage from these gaps can be prevented. The method of use, operation, action and effects other than the above are substantially the same as those of the fourth embodiment, and therefore, the repetitive description will be omitted.

  In the first to third embodiments, one set of attachment frames is attached to the upper frame portion of the window frame, but one set of attachment frames may be attached to a ceiling or a wall. Moreover, in the said 4th-5th embodiment, although the 1st frame unit was attached to the upper frame part of the window frame, you may attach a 1st frame unit to a ceiling or a wall. In the first to third embodiments, the first slat group unit is configured to have two sets of slat groups, but the first slat group unit is configured to have three or more sets of slat groups. You may In the fourth to fifth embodiments, the first frame unit has two sets of attachment frames, and the first slat group unit has two sets of slat groups. The unit may have three or more sets of mounting frames, and the first slat group unit may have three or more sets of slats. Also, in the first to fifth embodiments described above, a horizontal blind having a plurality of slats has been mentioned as the solar radiation shielding device, but a pleated screen having a zigzag or honeycomb shape screen, or a screen that becomes substantially flat when developed It may be a solar shading device such as Roman shade.

  In the fifth embodiment, the first slat group unit is controlled by the first controller, and another second slat group unit is controlled by the second controller. However, the second slat group unit is different from the first slat group unit. The slat group units may be simultaneously controlled by a single controller. In this case, the first slat group unit is moved backward to extend the first slat group unit and another second slat group unit simultaneously, or the first slat group unit is moved forward to move the first slat group unit. And one second slat group unit may be extended simultaneously, or another second slat group unit may be moved backward or forward to simultaneously extend the first slat group unit and the other second slat group unit. . Further, in the first to fifth embodiments, the fin member is not protruded toward the other second bottom unit on the bottom rail facing the other second bottom unit among the first bottom units. A fin member may be protruded toward the other second bottom unit or the like on a bottom rail facing the other second bottom unit or the like in the first bottom unit. In this case, when the first shield unit extends in the longitudinal direction, the fin member protruding from the first bottom unit approaches another second bottom unit or the like, and hence the second bottom unit different from the first bottom unit. Since the gap between them is substantially closed by the fin member, light leakage from the gap can be suppressed.

  Further, in the first to fifth embodiments, nothing is attached to the mutually opposing end faces of two adjacent sets of bottom rails, but these bottoms are attached to mutually opposite end faces of two adjacent sets of bottom rails. Female members and male members that extend the rails may be attached respectively. Specifically, a male member is protruded from one bottom rail, a female member is protruded from the other bottom rail, and the female member is fitted into the male member so as to be relatively movable. As a result, regardless of the extension or contraction in the longitudinal direction of the first slat group unit, the space between the adjacent bottom rails is kept closed by the female member and the male member, so that the first slat group unit is in the longitudinal direction. Even if the size of the slats is reduced, the generation of gaps in the depth direction between the slats due to the contact between the bottom rails can be prevented, and the light leakage from the polymerized slat group can be prevented. Further, in the first to fifth embodiments, nothing is attached to the mutually opposing end faces of two adjacent sets of bottom rails, but these bottoms are attached to mutually opposite end faces of two adjacent sets of bottom rails. A pair of band-shaped fin members extending the rails may be attached respectively. In this case, parts of the pair of fin members are polymerized with each other, and when the plurality of slats of the two sets of slats stand, the two sets of bottom rails also stand. As a result, even if the first slat group unit extends or contracts in the longitudinal direction, the two bottom rails stand up with the two slat groups and the gap between the adjacent bottom rails is closed by the fin member. Even if the slat group unit shrinks in the longitudinal direction, the generation of a gap in the depth direction between the slats due to the contact between the bottom rails can be prevented, and light leakage from the polymerized slat group can be prevented.

  In the second embodiment, each of the slats on the right side of the first slat group unit and the slats on the left side of the slat group on the left are sandwiched by a pair of horizontal cords, and the polymerization ladder cord is used as the overlapping portion. A polymerization ladder cord is provided on the right side of the overlapping part, provided on the left side and holding each slat of the left slat group with a pair of horizontal cords, but for each slat of the right slat group and the left slat group A ladder cord for polymerization is provided at the right of the overlapping part by suspending each slat by a pair of horizontal cords, and each ladder cord of the left slat group is interposed between a pair of horizontal cords. A polymerization ladder cord may be provided on the left side, or may be suspended by sandwiching each slat of the left and right slats with a pair of horizontal cords, and provided on the right or left of the overlapping portion, each slat of the left and right slats Pinched by a pair of horizontal cords The polymerization ladder cord in hanging lowering may be provided at the left portion or right portion of the overlapping portion. In the fourth and fifth embodiments, two sets of mounting frames are mounted on a window frame or the like in a state of being relatively movably connected in the longitudinal direction. Alternatively, the mounting frames may be mounted on a window frame or the like so as to be relatively movable in the longitudinal direction without connecting them.

  In the first to fifth embodiments, the first slat group unit is elongated in the longitudinal direction, so that the gap between the end faces facing each other between the first slat group unit and another second slat group unit is narrow. And the second ends of the second slat group unit are polymerized by extending the second slat group unit in the longitudinal direction. By extending the group unit in the longitudinal direction, the opposing ends of the first slat group unit and the other second slat group unit polymerize, and by extending the other second slat group unit in the longitudinal direction The polymerization length of the mutually opposing end of a 1st slat group unit and another 2nd slat group unit may be long. Further, in the first to fifth embodiments, another second slat group unit having two sets of slat groups partially polymerized is provided adjacent to the first slat group unit, but it extends in the longitudinal direction Another slat group that does not shrink may be provided adjacent to the first slat group unit. In this case, extension of the first slat group unit causes the first slat group unit to polymerize into another slat group.

  In the fifth embodiment, although the first slat group unit and the other second slat group units are configured to be unable to move up and down and to be tilted except for the initial state, respectively, it is not possible to move up and down or to tilt other than the initial state. Alternatively, the first slat group unit may be configured to move up and down or to tilt or not to move up and down except for the initial state. In the fifth embodiment, when the lower end of the first shield unit and the other second shield unit reaches the lower limit position or at a position close to the lower limit, the first shield unit and the other Although the second shield unit is configured to extend in the longitudinal direction, the first slat group unit is installed alone, and the lower end of the first slat group unit reaches the lower limit position or is close to the lower limit In position, the first shield unit may be configured to extend in its longitudinal direction. Furthermore, in the fifth embodiment, with the slats of the first slat group unit and the other second slat group unit being adjusted to the least light leak angle, the first slat group unit and the other The second slat group unit is configured to extend in its longitudinal direction, but the first slat group unit is installed alone, and the slats of the first slat group unit are adjusted to the least light leak angle, One slat group unit may be configured to extend in its longitudinal direction.
