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 can be raised and lowered. More specifically, the polymerization length is changed in a state where adjacent shields of the shield unit are overlapped, and the total amount of gaps where light leakage occurs is changed, so that the gaps and outside between the adjacent shields are changed. It relates to a solar radiation shielding device that prevents light leakage from the side surface.

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

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

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

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

JP-A-2014-20609 (Claims 1 and 2, paragraphs [0020], [0049], [0052], FIGS. 7A-7D, 10A, 10B) JP-A-2016-125260 (Claims 1 and 2, paragraphs [0003], [0019], [0069], [0081], FIGS. 1 to 7, 13, 13 and 15).

However, in the blind shown in the conventional patent document 1, the gaps between the slats are closed by abutting the end faces of the adjacent slats, so that light leakage occurs when the blind is viewed from the indoor side. The sum of the gap amounts, that is, the sum of the gap areas is the same. Therefore, in the blind shown in the above-mentioned conventional patent document 1, when the blind is installed so as to fit in the window frame, the total area of the gap cannot be reduced, and the entire inside of the window frame is slatted. Since it cannot be covered, there is also a problem that light leaks from the gap between adjacent slats or the outer surface of the adjacent slats.

On the other hand, in the shielding device shown in FIGS. 13 and 15 of the above-mentioned conventional patent document 2, when one elevating cord is inserted through a band-shaped shielding body having no weight member dedicated to the band-shaped shielding material, a string or the like is used. When the band-shaped shielding material is pulled in the moving direction, there is a problem that when the band-shaped shielding material moves laterally, the band-shaped shielding material is caught by the shielding material depending on the position of the shielding material and cannot move smoothly. Further, in the shielding device shown in the conventional patent document 2, since there is only one elevating cord inserted through the band-shaped shielding body, the shielding material is moved by a string to attach the string formed to the shielding material. There is also a problem that stress is applied to the contact portion between the hole and the string, and the string attachment hole becomes large due to the above stress depending on the fabric. Further, in the shielding device shown in FIGS. 2, 3 and 7 of the conventional Patent Document 2, if the thickness of the weight member is relatively thick, a gap is generated in the overlapping portion of the shielding material, and this gap is generated. There was also a problem that light leaked easily. Further, in the shielding device shown in the conventional Patent Document 2, when the strip-shaped shielding material is repolymerized on the shielding material in a state where the strip-shaped shielding material is moved to a position where it does not polymerize with the shielding material, the strip-shaped shielding material is further polymerized. However, there is also a problem that the strip-shaped shielding material cannot be smoothly polymerized on the shielding material in contact with the shielding body, and the work of polymerizing the strip-shaped shielding material on the shielding material is required.

A first object of the present invention is to change the total amount of gaps where light leakage occurs without using an auxiliary strip-shaped shield, so that the gaps between adjacent shields of the shield unit and the outer surface can be changed.

The usage and operation of the horizontal blind 10 configured in this way will be described. When blocking the light entering from the window in the rectangular window frame 16, first, the operation member 34 for raising / lowering / tilting the horizontal blind 10 is operated to simultaneously operate the slats 13a and 14a of the two sets of slats 13 and 14. It stands up and lowers the lower surfaces of the two sets of bottom rails 27 and 28 to the upper surface of the lower frame portion (not shown) of the window frame 16. Next, when the expansion / contraction operation member 43 is operated, the pulley rotates and the expansion / contraction drive shaft 37 rotates in the direction of the solid line arrow in FIG. The male screw member 38 is rotated in the same direction as the telescopic drive shaft 37 (the direction of the solid arrow in FIG. 2B), and the three female screw portions 41 on the right side are in the direction of the broken arrow in FIG. Move to the right. At the same time, the three male screw members 39 on the left side fitted with the telescopic drive shaft 37 rotate in the same direction as the telescopic drive shaft 37 (in the direction of the solid arrow in FIG. 3B), and the three female threads on the left side. The part 42 moves in the direction of the broken line arrow in FIG. 3B, that is, to the left. As a result, the non-polymerization take-up drum 19 and the non-polymerization tilting drum attached to the two non-polymerization drum holders 18 on the right side, and the polymerization tilting drum attached to the one polymerization drum holder on the right side. As the and the drum move to the right, the slat group 13 on the right side and the bottom rail 27 on the right side move to the right and approach the inner surface of the right frame portion (not shown) of the window frame 16. As a result, the polymerization lengths of the two adjacent sets of slat groups 13 and 14 become smaller, and the slat group unit 12 extends in the longitudinal direction, so that the total amount of gaps where light leakage occurs changes, and the slat group unit 12 covers almost all of the rectangular window frame 16. Therefore, it is possible to prevent the gap between the adjacent slat groups 13 and 14 of the slat group unit 12 and the light leakage from the outer surface of the slat group unit 12.

On the other hand, even if the slat group unit 12 is extended or contracted, the two adjacent slat groups 13 and 14 are kept in a polymerized state without being separated in the longitudinal direction. Can be prevented from leaking. Further, since the opposite ends of the bottom rails 27 and 28 of the bottom unit 26 are formed shorter than the slat groups 13 and 14, even if the slat group unit 12 is reduced in the longitudinal direction, the bottom rails 27 and 28 are connected to each other. It is possible to prevent the generation of a gap between the slat 13a and the slat 14a in the depth direction due to the contact of the slat 13a, and to suppress or prevent light leakage from the polymerized slat groups 13 and 14. As a result, although light leakage occurs between the bottom rails 27 and 28 due to the avoidance of polymerization of the bottom rails 27 and 28, the slat group unit 12 can be reliably reduced to a predetermined length. Further, since the slat groups 13 and 14 of the slat group unit 12 were suspended from the mounting frame 11 by two sets of non-polymerizing ladder cords 23 and 24 and one set of polymerization ladder cords 31 and 32, each slat group 13 , 14 can be hung in a stable state, and the polymerization lengths of two adjacent slat groups 13 and 14 can be smoothly changed. Further, in each of the slat groups 13 and 14, one set of the polymerization ladder codes 31 and 32 was provided in the polymerization section 33 of the adjacent slat groups 13 and 14, so that the polymerization section 33 of the slat groups 13 and 14 was manually provided. When pressed, it becomes difficult to release the alternately and regularly polymerized state. As a result, a part of the adjacent slat groups 13 and 14 of the slat group unit 12 is kept in a regularly polymerized state. Further, since the slat groups 13 and 14 of the slat group unit 12 are raised and lowered by the two non-polymerization lifting cords 21 and 22, the slat groups 13 and 14 can be raised and lowered in a stable state, and the adjacent slat groups can be raised and lowered. The polymerization lengths of 13 and 14 can be changed smoothly.

At this time, even if the right mounting frame 102 and the right bottom rail 27 try to come into contact with the inner surface of the right frame portion by operating the right operating rod 118, this contact is prevented by the stopper provided on the front slide rail 106. Even if they come into contact with each other, the frame cushioning member 117 attached to the end surface of the right mounting frame 102 and the bottom cushioning member 47 attached to the end surface of the right bottom rail 27 are attached to the right operating rod 118. Since the impact of the operation is absorbed, damage to the mounting frame 102 on the right side, the bottom rail 27 on the right side, and the slat group 13 on the right side can be prevented. Further, even if the left mounting frame 103 and the left bottom rail 28 try to come into contact with the inner surface of the left frame portion by operating the left operating rod 119, this contact is prevented by the stopper provided on the front slide rail 106. Even if they come into contact with each other, the frame cushioning member 117 attached to the end surface of the left mounting frame 103 and the bottom cushioning member 47 attached to the end surface of the left bottom rail 28 operate the left operating rod 119. It is possible to prevent damage to the mounting frame 103 on the left side, the bottom rail 28 on the left side, and the slat group 14 on the left side. As a result, as the frame unit 101 extends in the longitudinal direction, the polymerization lengths of the adjacent slat groups 13 and 14 become smaller, 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 gap between the adjacent slat groups 13 and 14 of the slat group unit 12 and the light leakage from 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 maintained in a polymerized state without being separated in the longitudinal direction. It is possible to prevent light from leaking. Further, since the slide connecting mechanism 104 is provided with a stopper that regulates 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, two sets of adjacent slat groups are adjacent to each other. The frame unit 101 does not extend to a length at which a part of the slat groups 13 and 14 is released from the polymerization state. As a result, a part of the two adjacent slat groups 13 and 14 can be reliably kept in a polymerized state. Since the usage, operation, action, and effect other than the above are substantially the same as those of the first embodiment, the repeated description will be omitted.

A free insertion hole 134b on the right side into which the elevating cord 137 is loosely inserted is formed. Specifically, the free insertion hole 133b on the left side is formed in the overlapping portion 138 of the two sets of slat groups 133 and 134 in the shape of an elongated hole extending in the front-rear direction on each slat 133a of the slat group 133 on the right side. It is composed of a left elongated hole 133c formed vertically connected to each other and a left square hole 134d formed vertically connected to each slat 134a of the left slat group 134. Then, the polymerization lifting cord 136 is inserted into the left elongated hole 133c and the left square hole 134d, one end thereof is attached to the left bottom rail 28, and the other end is inside the mounting frames 103 and 102 and the lifting / tilting operation member. It passes through the inside of 109 and is attached to the knob 111. Here, the length of the left square hole 134d in the front-rear direction is formed to be substantially the same as the length of the left long hole 133c, and the length of the left square hole 134d in the longitudinal direction is such that the slat group unit 132 is in the longitudinal direction. When expanded and contracted, the two sets of slat groups 133 and 134 are formed to a length that allows relative movement.

On the other hand, the free insertion hole 134b on the right side is formed in each slat 134a of the slat group 134 on the left side in the overlapping portion 138 of the two sets of slat groups 133 and 134 in a long hole shape extending in the front-rear direction and in the vertical direction. It is composed of a long hole 134c on the right side formed in a row and a square hole 133d on the right side formed in a quadrangular vertical direction in each slat 133a of the slat group 133 on the right side.

It is attached to the knob 111 through. Here, the length of the square hole 133d on the right side in the anteroposterior direction is formed to be substantially the same as the length of the elongated hole 134c on the right side, and the length of the square hole 133d on the right side in the longitudinal direction is such that the slat group unit 132 is in the longitudinal direction. When expanded and contracted, the two sets of slat groups 133 and 134 are formed to a length that allows relative movement. Other than the above, the configuration is the same as that of the fourth embodiment.

Since the polymerization lifting cord 137 is loosely inserted into the right side free insertion hole 134b, that is, the right side elongated hole 134c and the right side square hole 133d, even if the slat group unit 132 expands and contracts in the longitudinal direction, the left side for polymerization The elevating cord 136 moves in the longitudinal direction in the square hole 134d on the left side of the free insertion hole 133b on the left side, and the polymerization elevating cord 137 on the right side moves in the longitudinal direction in the square hole 133d on the right side of the free insertion hole 134b on the right side. All you have to do is move to. As a result, since the polymerization lifting cords 136 and 137 do not prevent the slat group unit 132 from expanding and contracting in the longitudinal direction, the slat group unit 132 can be expanded and contracted by a predetermined distance. Since the usage, operation, action, and effect other than the above are substantially the same as those of the fourth embodiment, the repeated description will be omitted.
