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 suspended from the mounting frame is configured to be capable of moving up and down. More specifically, the gap length between adjacent shields is changed by changing the sum of the gap amounts where light leakage occurs, with the polymerization length changing in a state where the adjacent shields of the shield unit are polymerized. The present invention relates to a solar radiation shielding device that prevents light leakage from the side.

  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. 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.

JP, 2014-206009, A (claims 1 and 2, paragraph [0020], [0049], [0052], Drawing 7A-Drawing 7D, Drawing 10A, Drawing 10B) JP, 2016-125260, A (claims 1 and 2, Paragraph [0003], [0019], [0069], [0081], Drawing 1-Drawing 7, Drawing 13, Drawing 15)

  However, in the case of the blind disclosed in the above-mentioned conventional patent document 1, light leakage occurs when the blind is viewed from the indoor side, since the gap between these slats is closed by butting the end faces of adjacent slats. The sum of the gap amounts, that is, the sum of the gap areas is the same. For this reason, in the case of the blind disclosed in the above-mentioned conventional Patent Document 1, when the blind is mounted so as to be contained in the window frame, the total sum of the areas of the gaps can not be reduced. There is also a problem that light can leak from the gap between adjacent slats or the outer surface of the adjacent slats because it can not be covered.

  On the other hand, in the case of the shielding apparatus shown in FIGS. 13 and 15 of the conventional Patent Document 2 described above, when one elevating cord is inserted in the band-shaped shield having no weight member dedicated to the band-shaped shielding material, When the strip-shaped shield material is pulled in the moving direction, the strip-shaped shield material is caught by the shield material depending on the position of the shield material when the strip-shaped shield material moves laterally, and there is a problem that smooth movement can not be performed. Further, in the shielding apparatus disclosed in the above-mentioned conventional Patent Document 2, since there is one lifting cord inserted in the band-shaped shielding body, the string attachment formed on the shielding material by moving the shielding material with 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. There is also a problem that light easily leaks from the Furthermore, in the shielding device disclosed in the above-mentioned conventional patent document 2, when it is attempted to polymerize the band-shaped shielding material again on the shielding material in a state where the band-shaped shielding material is moved to a position not polymerized with the shielding material, the band-shaped shielding material However, the strip-shaped shielding material can not be smoothly polymerized on the shielding material in contact with the shielding body, and there is also a problem that an operation of polymerizing the strip-shaped shielding material on the shielding material is required.

  In the solar radiation shielding apparatus according to the first aspect of the present invention, a part of the shield units adjacent to each other in the shield unit is polymerized so as to polymerize, and the polymerization length of the adjacent shields is polymerized. Since the shield unit is configured to expand and contract in the longitudinal direction due to the change in the length of the shield unit, the adjacent unit of the shield unit is changed by changing the sum of the gap amounts causing light leakage without using an auxiliary strip shield. It is possible to prevent light leakage from the gap between the matching shields and the outer surface of the shield unit. In addition, even if the shield unit is expanded or contracted, the adjacent shields of the shield unit are not separated in the longitudinal direction and are kept in a polymerized state, so that light can be prevented from leaking from between adjacent shields. .

  In the solar radiation shielding apparatus according to the second aspect of the present invention, at least two sets of mounting frames are provided extending in a straight line at intervals and configured to be relatively movable in the longitudinal direction, and adjacent ones of the shielding units The shield unit is configured to polymerize a part in the longitudinal direction of the shield, and the frame length extends or contracts in the longitudinal direction, and the polymerization length changes in a state in which the adjacent shields are polymerized. Since it is configured to expand and contract in the longitudinal direction, the gap between the adjacent shields of the shield unit and the shield can be blocked by changing the total sum of the gap amounts where light leakage occurs without using the auxiliary strip-shaped shield. Light leakage from the outer surface of the body unit can be prevented. In addition, even if the shield unit is extended or contracted together with the frame unit, the adjacent shields of the shield unit are kept apart without being separated in the longitudinal direction, and light is leaked from between the adjacent shields. Can be prevented.

  In the solar radiation shielding apparatus according to the third aspect of the present invention, at least two sets of bottom rails are respectively provided at lower ends of at least two sets of shields, and each bottom rail is formed shorter than each shield. Expansion and contraction in the direction does not cause the bottom rails to contact each other. As a result, although light leakage occurs from the gap between the bottom rails, the 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 disclosed in the conventional Patent Document 2 in which the strip-shaped shielding material is caught on the shielding material and can not move smoothly depending on the position of the shielding material, the present invention relates to the overlapping length of adjacent shielding members of the shielding unit. Can be changed smoothly.

  In the solar radiation shielding apparatus according to the fourth aspect of the present invention, since the band plate-like fin members extending the bottom rails are respectively attached to the mutually opposing end surfaces of the adjacent bottom rails of the at least two sets of bottom rails, Even if the shield unit extends and contracts in the longitudinal direction, the gap between the adjacent bottom rails is always closed by the fin member. As a result, it is possible to prevent light leakage between adjacent bottom rails.

  In the solar radiation shielding apparatus according to the fifth aspect of the present invention, a female member and a male member, which extend the bottom rails, are respectively attached to opposite end surfaces of adjacent bottom rails of at least two sets of bottom rails. Since it is inserted in the male member so as to be expandable and contractible, even if the shield unit is expanded and contracted in the longitudinal direction, the space between the adjacent bottom rails is always closed by the female member and the male member. As a result, it is possible to prevent light leakage between adjacent bottom rails.

  In the solar radiation shielding apparatus according to the sixth aspect of the present invention, since each shield of the shield unit is suspended by at least two sets of ladder cords or ladder tapes, each shield can be suspended in a stable state. The polymerization length of adjacent shields can be changed smoothly.

  In the solar radiation shielding apparatus according to the seventh aspect of the present invention, since at least one set of ladder cords or ladder tapes is provided at the overlapping portion of the adjacent shielding members, the shielding member is extended or contracted in the longitudinal direction. It becomes difficult to release the regular polymerization state of part of the adjacent shields of the unit. As a result, a part of adjacent shields of the shield unit is kept in a regularly polymerized state.

  In the solar radiation shielding apparatus according to the eighth aspect of the present invention, since each shield of the shield unit is configured to be moved up and down by at least two lifting cords and the like, each shield can be moved up and down in a stable state. The polymerization length of the matching shield can be changed smoothly.

  In the solar radiation shielding apparatus according to the ninth aspect of the present invention, at least one lifting cord is provided in the overlapping portion of the adjacent shielding members or outside the overlapping portion (longitudinal side of the ladder cords). Stretching in the longitudinal direction is possible.

  In the solar radiation shielding apparatus according to the tenth aspect of the present invention, since the loose insertion holes into which the lifting cords for polymerization are loosely inserted are formed in the overlapping portions of at least two sets of shields, the shield unit expands and contracts in the longitudinal direction Also, the polymerization state of a part of the adjacent shields of the shield unit becomes more difficult to be released. As a result, a part of the adjacent shields of the shield unit can be reliably kept in a polymerized state.

  In the solar radiation shielding apparatus according to the eleventh aspect of the present invention, since the stopper for restricting the amount of expansion and contraction in the longitudinal direction of at least two sets of shields is provided, the shield unit is extended even if the shield unit extends in the longitudinal direction. The shield unit does not extend to such a length that part of the adjacent shields is depolymerized. As a result, it is possible to reliably keep part of the adjacent shields of the shield unit in a polymerized state.

  In the solar radiation shielding apparatus according to the twelfth aspect of the present invention, at least two shields of the shield unit are at least two sets of slats of slat group units, and the adjacent slats of at least two sets of slats are Since a part in the longitudinal direction of each slat is alternately polymerized, the adjacent slat group units are adjacent to each other by changing the total of the amount of gaps in which light leaks occur without using an auxiliary strip shield. It is possible to prevent light leakage from the gap between the slat groups and the outer surface of the slat group unit. In addition, even if the slat group unit is extended or contracted, the adjacent slat groups of the slat group unit are kept apart without being separated in the longitudinal direction and kept in a polymerized state, so that light leakage from adjacent slat groups can be prevented. .

  In the solar radiation shielding apparatus according to the thirteenth aspect of the present invention, since the frame buffer member is attached to the end face in the longitudinal direction of the frame unit, the frame unit extends in the longitudinal direction and the end face of the mounting frame collides with the wall or the like. Even in this case, the shock absorbing member absorbs the shock due to the collision. As a result, damage to the shield, the mounting frame or the wall can be prevented.

  In the solar radiation shielding apparatus according to the fourteenth aspect of the present invention, since the bottom cushioning member is attached to the end face in the longitudinal direction of the bottom unit constituted by at least two sets of bottom rails, the shield unit extends in the longitudinal direction Even if the end surface of the bottom rail collides with a wall or the like, the shock absorbing member absorbs the shock due to the collision. As a result, damage to the shield, the bottom rail or the wall can be prevented.

As shown in FIG. 1, the solar radiation shielding device 10 is a horizontal blind in this embodiment. The horizontal blind 10 includes a set of mounting frames 11 attached to a window frame 16 and a slat group unit 12 having two sets of slat groups 13 and 14 respectively suspended from the mounting frame 11. One set of mounting frames 11 is mounted on the lower surface of the upper frame portion 16 a of the window frame 16 in a state of extending in the horizontal direction. Further, the mounting frame 11 is formed in the shape of a channel whose upper surface is open (FIGS. 4 and 5).

  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. Then, the lower surfaces of the two bottom rails 27 and 28 are lowered to the upper surface of the lower frame (not shown) of the window frame 16. 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. As a result, the polymerization length of two adjacent sets of slat groups 13 and 14 decreases, and the slat group unit 12 extends in the longitudinal direction, so that the total amount of gaps causing light leakage changes, and the slat group unit 12 cover substantially all of the rectangular window frame 16. Therefore, light leakage from the gap between the adjacent slat groups 13 and 14 of the slat group unit 12 and the outer surface of the slat group unit 12 can be prevented.

  On the other hand, even if the 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, so that light is emitted from between the adjacent slat groups 13 and 14 Can be prevented from leaking. Further, since the mutually opposing end portions of the bottom rails 27 and 28 of the bottom unit 26 are formed shorter than the slat groups 13 and 14, the bottom rails 27 and 28 can be fixed to each other even if the slat group unit 12 is contracted in the longitudinal direction. Generation of a gap between the slats 13a and the slats 14a in the depth direction due to the contact between the slats 13a and the slats 14a, and light leakage from the polymerized slat groups 13 and 14 can be suppressed or prevented. As a result, although light leakage occurs between the bottom rails 27 and 28 due to the polymerization avoidance of the bottom rails 27 and 28, the length can be reliably reduced to a predetermined length of the slat group unit 12. Further, since each slat group 13, 14 of the 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 group 13 , 14 can be suspended in a stable state, and the polymerization length of two adjacent sets of slats 13 and 14 can be changed smoothly. 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 the overlapping portion 33 of the slat groups 13, 14 is manually When pressed, it becomes difficult to release the alternately regularly polymerized state. As a result, a part of the adjacent slat groups 13, 14 of the slat group unit 12 is kept in a regularly polymerized state. Further, since each slat group 13, 14 of the slat group unit 12 is moved up and down by the two non-polymerization lifting cords 21, 22, the slat group 13, 14 can be moved up and down in a stable state, and adjacent slat groups The polymerization length of 13, 14 can be changed smoothly.

  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 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, so that the slat group unit 12 extends and contracts in the longitudinal direction. Configured Note that reference numerals 117 and 117 in FIGS. 9 and 10 denote a pair of frame buffer members attached to both end surfaces of the frame unit 101 in the longitudinal direction.

The base end is attached to the control rod and is gripped to move the left mounting frame 103 in the longitudinal direction. 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 blocking the light introduced from the window in the rectangular window frame 16, the slats 13a of the two sets of slats 13 and 14 are first operated by operating the elevation / tilting operation member 109 and the knob 111 of the horizontal blind 100. At the same time, the lower surfaces of the two sets of bottom rails 27 and 28 are lowered to the upper surface of the lower frame (not shown) of the window frame 16. Next, operate the right operating rod 118 in the right direction to make the right mounting frame 102 approach the right frame (not shown) of the window frame 16 and operate the left operating rod 119 in the left direction. The mounting frame 103 is moved close to the inner surface of the left frame (not shown) of the window frame 16. At this time, even if the right attachment frame 102 and the right bottom rail 27 try to abut the inner surface of the right frame by the operation of the right operating rod 118, this abutment is blocked by the stopper provided on the front slide rail 106. The frame buffer member 117 attached to the end face of the right mounting frame 102 and the bottom buffer member 47 attached to the end face of the bottom rail 27 on the right Since the shock due to the operation is absorbed, damage to the right mounting frame 102, the right bottom rail 27 and the right slat group 13 can be prevented. Further, even if the left mounting frame 103 and the left bottom rail 28 try to abut the inner surface of the left frame portion by the operation of the left operation rod 119, this abutment is blocked by the stopper provided on the front slide rail 106 The frame buffer member 117 attached to the end face of the left mounting frame 103 and the bottom buffer member 47 attached to the end face of the bottom rail 28 on the left operate the operation rod 119 even if it contacts or abuts Since the shock due to the shock is absorbed, damage to the left mounting frame 103, the left bottom rail 28 and the left slat group 14 can be prevented. As a result, when the frame unit 101 extends in the longitudinal direction, the polymerization length of the adjacent slat groups 13 and 14 decreases, and the slat group unit 12 extends in the longitudinal direction. The sum changes and the 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 slat group unit 12 and the outer surface of the slat group unit 12.

  On the other hand, even if the frame unit 101 is extended or contracted, the adjacent slat groups 13 and 14 of the slat group unit 12 are kept in a polymerized state without being separated in the longitudinal direction, so from between the adjacent slat groups 13 and 14 Light can be prevented from leaking. Further, since the slide connection mechanism 104 is provided with a stopper for restricting the amount of expansion and contraction of the two sets of slat groups 13 and 14 in the longitudinal direction, even if the slat group unit 12 extends in the longitudinal direction The frame unit 101 does not extend to such a length that part of the slat groups 13 and 14 is depolymerized. As a result, it is possible to reliably keep part of two adjacent sets of slat groups 13 and 14 in a polymerized state. 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.
