Description

The present invention is applied to the adherend of the ceiling, wall or window frame from the group consisting of a non-movable and non-stretchable first shielding unit, a movable second shielding unit and a stretchable third shielding unit. Two, three, or four or more selected shielding units including at least one second or third shielding unit are arranged in a row. The present invention relates to a solar radiation shielding device having a shielding unit group. More specifically, the present invention relates to a solar radiation shielding device that closes or reduces one end, the other end, or all of the gaps in the middle of a group of shielding units with an expandable unit to prevent or suppress light leakage.

Conventionally, a shielding material is vertically suspended from a support member fixed to a fixed surface, and the position at which the shielding material is suspended from the fixed surface in the state where the shielding material is lowered is determined by the support member. Blinds are disclosed that are configured to vary in the longitudinal direction of the 0052], FIGS. 7A-7D, FIGS. 8A-8D, FIGS. 10A and 10B).). In this blind, the shielding material moves up and down as the lifting cord that is vertically suspended from the supporting member moves up and down, and the drum on which the lifting cord can be wound moves in the longitudinal direction of the supporting member. The suspending position of the lifting cord moves in the longitudinal direction, and the shielding material moves integrally with the lifting cord. The drum has a drum receiver that cannot rotate relative to the support member, and a rotating drum that is rotatably supported by the drum receiver. configured to move to Further, the shielding material is configured to move in the longitudinal direction of the support member in conjunction with the elevation of the shielding material, or to move in the longitudinal direction of the support member after it descends to the lower limit position. Note that the head box itself, which is a support member, can be locked to the bracket so as to be movable in the longitudinal direction.

In the blind configured in this way, when the slats (shielding material) move in the longitudinal direction in the entire range of elevation, when the slats are raised to the upper limit position, the adjacent slats are separated to the maximum, A gap of the same size as the gap between the adjacent headboxes is formed, and as the slats descend, the slats move toward the adjacent slats, the gap between the adjacent slats gradually becomes smaller, and the slats reach the lower limit. When lowered to the position, the gap between the adjacent slats is closed. Further, when the slats move in the longitudinal direction after being lowered to the lower limit position, the gap between adjacent slats is constant while the slats are lowered from the upper limit position to the lower limit position, and after the slats are lowered to the lower limit position, By sliding the rotating shaft and the shielding material lifting device in the longitudinal direction, the slats are moved in the direction of the adjacent slats, and the gaps between the adjacent slats are closed. Therefore, the suspension position of the slat relative to the fixed surface when the slat is raised differs from the suspension position of the slat relative to the fixed surface when the slat is lowered. By changing the members in the longitudinal direction, the slats approach the window frame to reduce the gap between the slats and the window frame, and the adjacent slats approach each other to reduce the gap between the slats, thereby preventing light leakage. If the headbox itself, which is a supporting member, is engaged with the bracket so as to be movable in the longitudinal direction, the headbox itself can be manually moved in the longitudinal direction according to the elevation of the shielding material. As a result, the structure inside the headbox and below the headbox can be made similar to the existing blinds, and the existing blinds can be used.

However, in the conventional blind shown in Patent Document 1, when the head box itself, which is a supporting member, is locked to the bracket so as to be movable in the longitudinal direction, the head box itself is manually moved in the longitudinal direction. Also, there is a problem that the head box moves in the longitudinal direction together with the shielding material during the raising and lowering operation of the shielding material, and unintentionally comes into contact with the adjacent shielding material. In addition, in the blind disclosed in the conventional patent document 1, if the drum receiver and the rotating drum are of a sliding structure that moves along the support member in the longitudinal direction, the structure inside the support member becomes complicated. There was also a problem that the number of man-hours for manufacturing increased significantly.

To provide a solar radiation shielding device capable of reducing light leakage through the narrowed gap. A fourth object of the present invention is to provide a solar shading device that can reduce the number of telescopic units, thereby reducing the number of parts and assembly man-hours, and shortening the operating time of the telescopic units. A fifth object of the present invention is to provide a solar radiation shielding device capable of preventing damage to an obstacle or a group of shielding units due to contact during operation of an operating cord of an extendable unit. A sixth object of the present invention is to reduce the number of shield unit groups by constructing shield units whose ends are hidden by shields in the shield unit group from first shield units having fewer component parts. To provide a solar radiation shielding device which can be manufactured by increasing the number of man-hours and can be more easily installed at an installation site. A seventh object of the present invention is to provide a group of shield units even if the second or third shield unit is moved or expanded or contracted while the gap at one end of the group of shield units or the gap at the other end is hidden by a shield. Alternatively, there is provided a solar shielding device capable of preventing the side surface of the third shield unit from coming into contact with the side surface of the window frame, etc., and preventing the light from leaking into the room by blocking the light entering through the gap with the shield.

In the solar radiation shielding device according to the tenth aspect of the present invention, either one or both of the gap at one end of the group of shielding units and the gap at the other end of the group of shielding units are hidden by a shield, and Since the shield unit having the other end hidden by the shield is composed of the first shield unit, the first shield unit cannot move in the longitudinal direction and cannot expand and contract in the longitudinal direction. Even if the gap is not closed or reduced at the edge hidden by the shield, no light leakage occurs from this edge. As a result, the shielding units whose ends are hidden by the shields in the shielding unit group can be configured with the first shielding unit having a small number of constituent parts, so that the shielding unit group can be manufactured with a smaller increase in the number of man-hours. It can be installed more easily at the installation site.

No noise is generated. Alternatively, the second shielding unit or the third shielding unit may be moved or reduced in the direction of increasing the gap at one end of the group of shielding units or the gap at the other end that is hidden by the shield. Since the gap cannot be visually recognized through the shield when viewed from the inside of the room from the front, the light entering through the gap is blocked by the shield and can be prevented from leaking into the room.

The drive shaft 27c is provided so as to protrude downward from the bottom plate 29h of the holder main body 29a, and a pulley 27d is fitted to the protruding end of the drive shaft 27c. Furthermore, the drive source 28 is an extendable operation cord wound around the pulley 27d in this embodiment. 2 to 5 denotes a cover body that covers the driven gear 27a, the drive gear 27b, the pulley 27d, etc. exposed from the holder body 29a. The cover body 34 is formed in a substantially U shape that is one size larger than the holder body 29a.

On the other hand, in this embodiment, both the gap 11a at one end and the gap 11b at the other end of the shielding unit group 11 are configured to be hidden by shields 36 such as curtains and pillars (FIGS. 1 and 5). ). A shield unit having an end hidden by the shield 36 at one end of the shield unit group 11 is composed of the second shield unit 12 and is hidden by the shield 36 at the other end of the shield unit group 11. A second shield unit 12 constitutes a shield unit with tapered ends. The end portion of the second shield unit 12 located at one end side of the shield unit group 11, which is hidden by the shield 36, faces the window frame side surface or wall surface (not shown), and faces the other end of the shield unit group 11. The end hidden by the shield 36 of the second shield unit 12 located on the side is configured to face a window frame side surface or a wall surface (not shown). Furthermore, the gap 11a at one end of the shielding unit group 11 and the gap 11b at the other end are such that when the second shielding unit 12 is moved in its longitudinal direction, the side surface of the second shielding unit 12 becomes a window. The gaps 11a and 11b are set so as not to come into contact with the side surfaces of the frame or the like and to be invisible from the side edges of the shield 36 when viewed from the front from the inside of the room.

The operation of the solar radiation shielding device 10 configured in this way will be described. The first telescopic unit 21 attached to the adherend 13 moves the two second shield units 12, 12 in the longitudinal direction, thereby closing or reducing the gap 11c between the shield unit groups 11. . Specifically, when the telescopic operation cord 28 is operated, the rotational force generated by this operation is transmitted to the output shaft 23 via the pulley 27d, drive gear 27b and driven gear 27a of the rotational force transmission mechanism 27. FIG. Next, the rotational force transmitted to the output shaft 23 engages the first and second male threaded portions 31a, 32a with the first and second female threaded portions 24a, 26a, respectively, causing the first and second slide members 24 to move. , 26 movements, respectively. Further, the two second shield units 12, 12 engaged with the first and second slide members 24, 26 respectively move toward each other, and the first and second slide members 24, 26 move toward the holder body 29a. They abut on the pair of side plates 29f and 29g (Fig. 4). As a result, by operating the expansion/contraction operation cord 28, the intermediate gap 11c of the shield unit group 11 can be closed or reduced (FIGS. 1(b) and 4). Unless the first extensible unit 21 attached to the adherend 13 is operated, the second shielding unit 12 cannot be moved in its longitudinal direction. is not closed or contracted, the second shielding unit 12 does not move in its longitudinal direction, and the adjacent second shielding units 12, 12 do not move unintentionally. Contact can be suppressed.

The two second shield units 12, 12 are fixed to the head rail 16 by removing the cushion member from the bracket of the first shield unit, which is a conventionally known general horizontal blind. The end cap 16a can be inserted into the first and second recesses 24b and 26b of the first and second slide members 24 and 26, so that the shield unit group 11 can be relatively small. It can be manufactured with an increased number of man-hours and can be installed relatively easily at the installation site.

On the other hand, when the gap 11a at one end of the shield unit group 11 and the gap 11b at the other end of the shield unit group 11 are shifted in the longitudinal direction of the two second shield units 12, 12, the size of the second shield unit The side surfaces of the shields 12 and 12 are set so as not to abut on the side surfaces of the window frame and the like, and the gaps 11a and 11b are set so as to be invisible from the side edges of the shields 36 and 36 when viewed from the front from the inside of the room. Even if the two second shielding units 12, 12 are moved in a direction to reduce the gap 11a at one end and the gap 11b at the other end of the unit group 11, the side surfaces of the second shielding units 12, 12 will be the window frame side surfaces. etc., and even if the second shielding units 12, 12 are moved in the direction of increasing the gap 11a at one end and the gap 11b at the other end of the shielding unit group 11, the gaps 11a, 11b are It cannot be visually recognized from the side edges of the shields 36, 36 when viewed from the front from the inside of the room. As a result, no abnormal noise is generated due to the contact, and the light entering through the gaps 11a and 11b is blocked by the shields 36 and can be prevented from leaking into the room.

<Second Embodiment>
6 to 8 show a second embodiment of the invention. 6 to 8, the same reference numerals as in FIGS. 1 to 4 denote the same parts. In this embodiment, a solar radiation shielding device 50 includes a shielding unit group 51 in which a second shielding unit 12 and a first shielding unit 61 are arranged in a row on an adherend 13 (FIG. 6). That is, in this embodiment, of the two second shield units in the first embodiment, the second shield unit on the other end side (left side) is replaced with the first shield unit 61 . The first shielding unit 61 is attached to the adherend 13 so as not to stretch in the longitudinal direction and to move in the longitudinal direction. Specifically, there is a conventionally known general structure in which a cushion member (not shown) is attached between a pair of brackets (not shown) of the first shield unit 61 and the head rail 16 to prevent skidding. horizontal blinds.

On the other hand, the second extendable unit 52 is attached so as to be positioned in the gap 51c between the shielding units 51, that is, in the gap 51c between the second shielding unit 12 and the first shielding unit 61. It is attached to the body 13 (Fig. 6). By moving the second shielding unit 12 in its longitudinal direction, the second telescopic unit 52 can close or reduce the gap 51c in the middle of the shielding unit group 51 . That is, the intermediate gap 51c of the shield unit group 51 is configured to be closed or contracted by moving the second shield unit 12 located on one side of the gap 51c by the second extendable unit 52. (FIGS. 6(b) and 8). Further, in the second extensible unit 52 of this embodiment, the second boss portion having the second male screw portion on the outer peripheral surface of the first extensible unit of the first exemplary embodiment has the second male screw portion on the outer peripheral surface. , and the second slide member having the second female thread is removed. 7 and 8). Then, by inserting the end cap 16a fixed to the head rail 16 of the second shield unit 12 so as not to come off into the first concave portion 24b of the first slide member 24, the first slide member 24 expands and contracts in a second manner. It is engaged with the second shield unit 12 located on the right side of the unit 52 .

On the other hand, in this embodiment, the gap 51a at one end of the shield unit group 51 is hidden by the shield 36 (FIG. 6). A shield unit having an end hidden by the shield 36 at one end of the shield unit group 51 is constituted by the second shield unit 12 and is hidden by the shield 36 at the other end of the shield unit group 51. A first shield unit 61 constitutes a shield unit having a tapered end. The end of the second shield unit 12 located at one end of the shield unit group 51, which is hidden by the shield 36, faces the window frame side surface or wall surface (not shown), and the other end of the shield unit group 51 The end hidden by the shield 36 of the first shield unit 61 located on the side is configured to face the window frame side surface or wall surface (not shown). Furthermore, the size of the gap 51a at one end of the shielding unit group 51 is such that when the second shielding unit 12 is moved in its longitudinal direction, the side surface of the second shielding unit 12 comes into contact with the side surface of the window frame or the like. and the gap 51a is set so as to be invisible from the side edge of the shield 36 when viewed from the front from the inside of the room. The size of the gap 51b at the other end of the shielding unit group 51 does not change because the first shielding unit 61 neither moves nor expands or contracts in its longitudinal direction. The configuration other than the above is the same as that of the first embodiment.

The operation of the solar radiation shielding device 50 configured in this way will be described. The second telescopic unit 52 attached to the adherend 13 moves the second shielding unit 12 in its longitudinal direction to close or reduce the intermediate gap 51c of the shielding unit group 51 . Specifically, the expansion/contraction operation cord 28 of the second expansion/contraction unit 52 is connected to the group 5, and the rotational force generated by this operation is transmitted through the pulley 27d, driving gear 27b, and driven gear 27a of the rotational force transmission mechanism 27 to the output shaft 23. is transmitted to Next, the rotational force transmitted to the output shaft 23 is converted into movement of the first slide member 24 by meshing of the first male threaded portion 31a with the first female threaded portion 24a. Further, the second shield unit 12 engaged with the first slide member 24 moves in a direction approaching the first shield unit 61, and the first slide member 24 contacts the pair of side plates 29f and 29g of the holder main body 29a. (Fig. 8). As a result, by operating the expansion/contraction operation cord 28, the gap 51c in the middle of the shield unit group 51 can be closed or reduced (FIGS. 6(b) and 8). Unless the second extensible unit 52 attached to the adherend 13 is operated in this way, the second shielding unit 12 cannot be moved in its longitudinal direction. is not closed or contracted, the second shield unit 12 does not move in its longitudinal direction even if the second shield unit 12 is operated up and down. Unintentional contact with can be suppressed.

On the other hand, since the first shield unit 61 is a conventionally known general horizontal blind, it does not need to be changed at all. The second shield unit 12 has an end cap which is fixed to the head rail 16 by removing a cushion member from the bracket of the first shield unit 61 which is a conventionally known general horizontal blind. A slight change of changing the shape of 16a into a shape that can be inserted into the first concave portion 24b of the first slide member 24 is sufficient. Further, by simply inserting the end cap 16a fixed to the head rail 16 of the second shield unit 12 so as not to come off into the first concave portion 24a of the first slide member 24 of the second extensible unit 52, the first slide can be performed. Since the member 24 is engaged with the second shield unit 12 located on the right side of the second telescopic unit 52, only a slight modification of the structure of the second shield unit 12 is required. As a result, the shield unit group 51 can be manufactured with a relatively small increase in man-hours, and can be installed at the installation site relatively easily.

On the other hand, when the second shield unit 12 is moved in its longitudinal direction, the side surface of the second shield unit 12 comes into contact with the side surface of the window frame or the like. and the gap 51a is set so as to be invisible from the side edge of the shield 36 when viewed from the front from the inside of the room. Even if the body unit 12 is moved, the side surface of the second shielding unit 12 does not come into contact with the side surface of the window frame or the like. Even if 12 is moved, the gap 51a cannot be visually recognized from the side edge of the shield 36 when viewed from the front from the inside of the room. As a result, no abnormal noise is generated due to the contact, and light entering through the gap 51a is blocked by the shield 36, thereby preventing light from leaking into the room.

The two mounting frames 86 , 86 are arranged in a row with a gap therebetween, and are formed identically to the head rail 61 of the first shield unit 61 except for the length and the collapsible portion 97 that expands and contracts. Then, by removing a cushion member (not shown) interposed between the pair of brackets 95 and 95 of the first shield unit 61 and the mounting frame 86 for preventing sideslip, the mounting frame 86 can be attached to the pair of brackets 85 by removing the cushion member (not shown). , 85 in the longitudinal direction of the mounting frame 86 .

The second expandable unit 52 is attached so as to be positioned in the gap 81c between the shielding unit group 81, that is, in the gap 81c between the third shielding unit 83 and the first shielding unit 61. It is attached to the body 13 (Figs. 9 and 10). A first concave portion is formed in the lower surface of the first slide member of the second extendable unit 52, and the third shield unit 83 is fixed to the other (left) mounting frame 86 in this first concave portion so as not to come off. By inserting the closed end cap, the first slide member is engaged with the third shield unit 83 located on the right side of the second telescopic unit 52 . By extending the third shield unit 83 in its longitudinal direction, the second extendable unit 52 can close or reduce the intermediate gap 81c of the shield unit group 81 .

The rotary shafts 87, 87 protrude from the mounting frames 86, 86 in directions toward each other, and a connecting cylinder 88 is fitted to the protruding ends of the shafts 87, 87. One end of the connecting tube 88 is fitted so as to be non-rotatable and movable in the longitudinal direction with respect to the one (right) rotating shaft 87 , and the other end of the connecting tube 88 rotates with respect to the other (left) rotating shaft 87 . incapable of moving longitudinally. As a result, even if the two mounting frames 86 , 86 move relative to each other in the longitudinal direction, the rotational force of one rotating shaft 87 is always transmitted to the other rotating shaft 87 .

The two non-polymerization drum holders have two non-polymerization winding drums 91, 91 for unreeling the two non-polymerization elevating cords 89, 89, and two sets of non-polymerization ladder cords.

On the other hand, two sets of slat groups 84, 84 are suspended from two mounting frames 86, 86, respectively, and configured to be vertically movable (FIG. 10). Specifically, the two sets of slat groups 84, 84 are each composed of a plurality of slats 84a, 84a extending horizontally and provided at predetermined intervals in the vertical direction. A longitudinal portion of each slat 84a, 84a is configured to overlap alternately. Two bottom rails 94, 94 are provided at the lower ends of the two sets of slat groups 84, 84, respectively. Specifically, the two bottom rails 94, 94 extend horizontally so as to be positioned immediately below the lowest slats 84a, 84a among the plurality of slats 84a, 84a of the two sets of slat groups 84, 84. be done. Of the two sets of slat groups 84 , 84 , the right slat group 84 is suspended by two sets of non-overlapping ladder cords 92 , 92 on the right side and one set of overlapping ladder cords 96 . The left slat group 84 of the two slat groups 84, 84 is suspended by the two left non-overlapping ladder cords 92, 92. As shown in FIG. Here, when a part of each of the slats 84a, 84a of the two adjacent slat groups 84, 84 is alternately overlapped is referred to as an overlapping portion 97, the right non-overlapping ladder cord 92 is connected to the right slat group 84. , the left non-overlapping ladder cord 92 suspends the left slat group 84 at a portion other than the overlapping portion 97, and the overlapping ladder cord 96 suspends the right slat group 84 at the overlapping portion 97. configured to hang. By moving either one or both of the two mounting frames 86, 86 in the longitudinal direction, the overlapping length of the adjacent slat groups 84, 84 is changed in the overlapping state, and the third shielding body A unit 83 is configured to extend and contract in the longitudinal direction.

When the third shield unit 83 expands and contracts, the overlapping ladder cords 96 are arranged so as to suppress the sliding resistance acting between the two adjacent slat groups 84 , 84 and the overlapping ladder cords 96 in the overlapping portion 97 . is provided in the overlapping portion 97 (FIG. 10). In this embodiment, the overlapping ladder cord 96 is the pair of overlapping ladder cords 96 that hold the right slat group 84 of the two adjacent slat groups 84 , 84 at the overlapping portion 97 . The lower end of a pair of vertical strings 96a for polymerization of one set of ladder cords 96 for polymerization is attached to the bottom rail 94 on the right side, and the upper end is attached to the tilting drum 98 for polymerization fitted on the rotating shaft 87 ( 10 and 11). The tilting drum for polymerization 98 is rotatably attached to a drum holder for polymerization (not shown) provided in the mounting frame 86 . When the rotating shaft 87 rotates forward or backward by an angle of less than 90 degrees, the tilting drum for polymerization 98 rotates together with the rotating shaft 87 , and the ladder cord 96 for polymerization is integrated with the tilting drum for polymerization 98 . configured to rotate; On the other hand, when the rotating shaft 87 rotates forward or backward by 90 degrees or more, the rotation of the tilting drum 98 for polymerization stops, and the slats 84a, 84a of the two sets of slat groups 84, 84 are tilted by 90 degrees or more. configured to disappear. The ends of the two sets of bottom rails 94, 94 that face each other are designed so that the two bottom rails 94, 94 do not come into contact with each other regardless of the expansion and contraction of the third shield unit 83 in the longitudinal direction. It is formed shorter than each slat 84a, 84a of the slat groups 84,84.

On the other hand, the two non-overlapping elevating cords 89, 89 on the right side serve for the right slat group 84, and the two non-overlapping elevating cords 89, 89 on the left side serve for the left slat group 84. (Fig. 10). These non-overlapping elevating cords 89, 89 are provided in portions of the two sets of slat groups 84, 84 that are not the overlapping portion 97, respectively. One ends of the two right non-overlapping elevating cords 89 and 89 are respectively attached to the right bottom rail 94 , and the other ends of these non-overlapping elevating cords 89 and 89 are attached to the right slat group 84 . After loosely inserted into the slats 84a, they are attached to the two winding drums 91, 91 for non-polymerization on the right side. Furthermore, one ends of the two left non-overlapping elevating cords 89 and 89 are attached to the left bottom rail 94 respectively, and the other ends of these non-overlapping elevating cords 89 and 89 are attached to the left slat group 84 respectively. After being loosely inserted into the slat 84a, it is attached to the two winding drums 89, 89 for non-polymerization on the left side. Reference numeral 99 in FIG. 10 denotes an up/down tilting operation cord attached to the front right portion of the right attachment frame 86 . The lifting/tilting operation cord 99 is connected to the rotary shaft 87 via pulleys and gears (not shown) in order to raise/lower or tilt the slats 84a, 84a of the two slat groups 84, 84 at the same time. By operating the lift/tilt operation cord 99, the two rotating shafts 87, 87 are rotated simultaneously, and the non-overlapping lifting/lowering cord 89 is wound on the non-overlapping winding drum 91 or the non-overlapping winding drum 91 is rotated. By being let out from the take-up drum 91, the two sets of slat groups 84, 84 can be raised and lowered simultaneously, and the front and rear of the non-polymerizing ladder cord 92 and the polymerizing ladder cord 96 move up and down to move the two sets of slats. By tilting the slats 84a, 84a of the groups 84, 84 forward or backward, the tilt angles of these slats 84a, 84a can be changed simultaneously. Reference numerals 101, 102 and 103 in FIG. 11 denote the rotation shaft, winding drum and tilting drum of the first shield unit 61. As shown in FIG. The configuration other than the above is the same as that of the first embodiment.

The operation of the solar radiation shielding device 80 configured in this way will be described. The second stretchable unit 52 attached to the adherend 13 stretches the third shield unit 83 in its longitudinal direction to close or reduce the intermediate gap 81c of the shield unit group 81 . Specifically, when the expansion/contraction operation cord 28 of the second expansion/contraction unit 52 is operated, the rotational force generated by this operation is transmitted through the pulley 27d, the drive gear 27b, and the driven gear 27a of the rotational force transmission mechanism 27 to the output shaft 23. is transmitted to Next, the rotational force transmitted to the output shaft 23 is converted into movement of the first slide member 24 by meshing of the first male threaded portion 31a with the first female threaded portion 24a. Furthermore, the third shield unit 83 engaged with the first slide member 24 moves in the direction approaching the first shield unit 61, and the first slide member 24 comes into contact with the pair of side plates 29f and 29g of the holder main body 29a. . As a result, by operating the expansion/contraction operation cord 28 of the second expansion/contraction unit 52, the intermediate gap 81c of the shield unit group 81 can be closed or reduced (FIGS. 9(b) and 10(b)). Unless the second telescopic unit 52 attached to the adherend 13 is operated, the third shielding unit 83 cannot be stretched in its longitudinal direction. When the third shield unit 83 is not closed or contracted, the third shield unit 83 does not expand or contract in its longitudinal direction, and the first shield unit 61 of the third shield unit 83 does not expand or contract. Unintentional contact with can be suppressed.

The third shield unit 83 has two mounting frames 86, 86 each mounted on the adherend 13 so as to be relatively movable, and is constructed such that the two sets of slat groups 84, 84 can be lifted and tilted at the same time. Although it is a special horizontal blind, an end cap 86a fixed to the mounting frame 86 of the third shield unit 83 is inserted into the first recess 24b of the first slide member 24 of the second telescopic unit 52. As a result, the first sliding member 24 is engaged with the third shielding unit 83 located on the right side of the second telescopic unit 52, so that only a slight modification of the structure of the third shielding unit 83 is required. As a result, although the man-hours for manufacturing and installing the shield unit group 81 of the present embodiment are increased to some extent compared to the shield unit groups of the first and second embodiments, the man-hours for manufacturing and installing the shield unit group 81 of the present embodiment can be reduced.

On the other hand, even if the left end of the third shielding unit 83 expands and contracts, the size of the gap 81a at one end of the shielding unit group 81 is such that the right end of the third shielding unit 83 does not move in its longitudinal direction. ,It does not change. Also, the side surface of the third shielding unit 83 is set so as not to abut on the side surface of the window frame and the like, and the gap 81a is set so as to be invisible from the side edge of the shielding object 36 when viewed from the front from the inside of the room. As a result, no abnormal noise is generated due to the contact, and light entering through the gap 81a is blocked by the shield 36, thereby preventing light from leaking into the room.

The gap 111c in the middle of the body unit group 81 can be closed or contracted.

Also, the third shield unit 83 is located in the gap 111a at one end of the shield unit group 111, that is, in the gap 111a between the right end of the third shield unit 83 on the right side and the right frame portion 112a of the window frame 112. 2 telescopic unit 52 is attached to the adherend. Then, by inserting an end cap that is fixed to one (right) mounting frame 86 of the right third shield unit 83 so as not to come off, into the first concave portion of the first slide member of the second extendable unit 52 . , the first slide member is engaged with the third shield unit 83 located on the left side of the second telescopic unit 52, and the second telescopic unit 52 extends the third shield unit 83 on the right side in its longitudinal direction. , the gap 111a at one end of the shield unit group 111 can be closed or contracted. Furthermore, it is located in the gap 111b at the other end of the shield unit group 111, that is, in the gap 111b between the left end of the left third shield unit 83 and the left frame portion 112b of the window frame 112. A second telescopic unit 52 is attached to the adherend. Then, by inserting the end cap fixed to the other (left) mounting frame 86 of the left third shield unit 83 into the first concave portion of the first slide member of the second extensible unit 52 so as not to come off. , the first sliding member is engaged with the third shield unit 83 located on the right side of the second telescopic unit 52, and the second telescopic unit 52 extends the third shield unit 83 on the left side in its longitudinal direction. , the gap 111b at the other end of the shielding unit group 111 can be closed or contracted. In the vicinity of the gap 111a at one end of the shield unit group 111 and the gap 111b at the other end, obstacles (not shown) such as plants are placed respectively. The expansion/contraction operation cord of the right second expansion/contraction unit 52 is arranged at a position where the expansion end of the right third shield unit 83 can be operated while avoiding contact with an obstacle. The expansion/contraction operation cord of the second expansion/contraction unit 52 on the left side is arranged at a position where the expansion end of the shield unit 83 can be operated while avoiding contact with an obstacle. The configuration other than the above is the same as that of the third embodiment.

The operation of the solar radiation shielding device 110 configured in this way will be described. When the expansion/contraction operation cord of the first expansion/contraction unit 21 is operated, the two third shield units 83, 83 respectively engaged with the first and second slide members are expanded in a direction toward each other, and the first and second slide members are extended. The members abut against the pair of side plates of the holder body. As a result, by operating the expansion/contraction operation cord of the first expansion/contraction unit 21, the intermediate gap 111c of the shield unit group 111 can be closed or contracted. Further, when the telescopic operation cord of the right second telescopic unit 52 is operated, the right third shield unit 83 engaged with the first slide member extends in a direction approaching the right frame portion 112a of the window frame 112, The first slide member abuts on the pair of side plates of the holder body. As a result, the gap 111a at one end of the shield unit group 111 can be closed or reduced by operating the expansion/contraction operation cord of the second expansion/contraction unit 52 on the right side. Furthermore, when the telescopic operation cord of the left second telescopic unit 52 is operated, the left third shield unit 83 engaged with the first slide member extends in a direction approaching the left frame portion 112b of the window frame 112, The first slide member abuts on the pair of side plates of the holder body. As a result, by operating the expansion/contraction operation cord of the second expansion/contraction unit 52 on the left side, the gap 111b at the other end of the shield unit group 111 can be closed or reduced. Unless the first and second telescoping units 21 and 52 attached to the adherend are operated, the third shielding unit 83 cannot be stretched in its longitudinal direction. Even if the third shield unit 83 is moved up and down while the middle gap 111c, the gap 111a at one end, and the gap 111b at the other end are not closed or reduced, the third shield unit 83 will not expand or contract in its longitudinal direction. First, unintended contact between the third shield units 83, 83, unintended contact with the right frame portion 112a of the third shield unit 83 on the right side, and contact with the left frame portion 112b of the third shield unit 83 on the left side. Unintentional contact can be suppressed.

On the other hand, when the third shield unit 83 on the right side is extended by manipulating the operation cord for extension and retraction of the second extendable unit 52 on the right side, an obstacle exists near the gap 111a at one end of the shield unit group 111. The extended end of the right third shield unit 83 may come close to contacting an obstacle. At this time, in order to avoid the above-mentioned contact, the operator operates the expansion/contraction operation cord of the second expansion/contraction unit 52 on the right side while holding the obstacle by hand. As a result, damage to the obstacle or the third shield unit 83 on the right side due to the contact can be prevented. Also, when the expansion/contraction operation cord of the second expansion/contraction unit 52 on the left side is operated to extend the third shielding unit 83 on the left side, there is an obstacle near the gap 111b at the other end of the shielding unit group 111. , the extended end of the left third shield unit 83 may come into contact with an obstacle. At this time, in order to avoid the above-mentioned contact, the operator operates the expansion/contraction operation cord of the second expansion/contraction unit 52 on the left side while holding the obstacle by hand. As a result, damage to the obstacle or the third shield unit 83 on the left side due to the contact can be prevented.

On the other hand, the third shield unit 83 has two mounting frames 86, 86 attached to the adherend so as to be able to move relative to each other, and is a special horizontal type configured so that two sets of slat groups can be lifted and tilted at the same time. Blinds. However, if the end cap fixed to the mounting frame 86 of the right third shield unit 83 is inserted into the first concave portion of the first slide member of the first telescopic unit 21, the first telescopic unit 21 will not move. The first slide member is engaged with the third shield unit 83 on the right side, and the second recess of the second slide member of the first telescopic unit 21 prevents the mounting frame 86 of the third shield unit 83 on the left side from falling off. , the second slide member of the first telescopic unit 21 is engaged with the third shield unit 83 on the left. When the end cap fixed to the mounting frame 86 of the right third shield unit 83 is inserted into the first concave portion of the first slide member of the right second extensible unit 52, the right second telescoping unit 52 slides into the first recess. The first slide member of the telescopic unit 52 is engaged with the right third shield unit 83, and the left third shield unit 83 is attached to the first recess of the first slide member of the left second telescopic unit 52. When the end cap fixed to the frame 86 is inserted, the first slide member of the left second telescopic unit 52 is engaged with the left third shield unit 83 . In this manner, when there is no shield such as the shield unit groups of the first to third embodiments, the structure of the third shield unit 83 can be changed with relatively few changes.

<Fifth Embodiment>
FIG. 13 shows a fifth embodiment of the invention. 13, the same reference numerals as in FIGS. 1, 9 and 12 denote the same parts. In this embodiment, the solar radiation shielding device 130 includes a shielding unit group 131 in which the third shielding unit 83 and the second shielding unit 12 are arranged in a row on the adherend. That is, in this embodiment, the first shield unit on the other end side (left side) in the third embodiment is replaced with the second shield unit 12 . Further, in this embodiment, the third shield unit 83 is positioned in the middle gap 131c of the shield unit group 131, that is, in the gap 131c between the third shield unit 83 and the second shield unit 12. 3 telescopic unit 133 is attached to the adherend. This third telescopic unit 133 differs from the first telescopic unit of the first embodiment in the following points. Although not shown, the third extensible unit 133 has the same spiral direction of the first male threaded portion and the first female threaded portion and the spiral direction of the second male threaded portion and the second female threaded portion. The lead of the first female threaded portion is formed larger than the leads of the second male threaded portion and the second female threaded portion. The configuration of the third telescopic unit 133 other than the above is the same as the configuration of the first telescopic unit of the first embodiment.

Then, the end cap fixed to the other (left) mounting frame 86 of the right third shield unit 83 is inserted into the first concave portion of the first slide member of the third extensible unit 133 so as not to come off. By inserting an end cap fixed to the head rail 16 of the left second shield unit 12 so as not to come off into the second concave portion of the second slide member, the first and second slide members are moved to the third telescopic unit 133 . are engaged with the third shielding unit 83 and the second shielding unit 12 located on both sides of the . Before the third shielding unit 83 is extended by the third extendable unit 133 and before the second shielding unit 12 is moved, the gap 131c in the middle of the shielding unit group 131 is larger than the gap 13b at the other end. are formed identically. Then, the third telescopic unit 133 extends the third shield unit 83 in its longitudinal direction and moves the second shield unit 12 in its longitudinal direction, thereby moving the intermediate gap 131c of the shield unit group 131 and other parts. The gap 131b at the end can be closed or contracted at the same time. That is, the middle gap 131c and the gap 131b at the other end of the shielding unit group 131 allow the third shielding unit 83 and the second shielding unit 12 to extend and move in the same direction by the third expansion/contraction unit 133. By making the extension amount of the third shield unit 83 larger than the movement amount of the second shield unit 12, it is configured to be closed or contracted.

On the other hand, the second expansion and contraction is performed so as to be positioned in the gap 131a at one end of the shield unit group 131, that is, to be positioned in the gap 131a between the right end of the third shield unit 83 and the right frame portion 112a of the window frame 112. A unit 52 is attached to the adherend. Then, by inserting an end cap fixed to one (right) mounting frame 86 of the third shield unit 83 so as not to come off into the first concave portion of the first slide member of the second extendable unit 52, the One slide member is engaged with the third shield unit 83 located on the left side of the second telescopic unit 52 . The gap 131a at one end of the shield unit group 131 can be closed or contracted by the second extendable unit 52 extending the third shield unit 83 in its longitudinal direction. That is, the gap 131a at one end of the shielding unit group 131 is configured to be closed or contracted by extending the third shielding unit 83 located on the left side of the gap 131a by the second expansion/contraction unit 52 . The configuration other than the above is the same as that of the third embodiment.

The operation of the solar radiation shielding device 130 configured in this way will be described. When the expansion/contraction operation cord of the third expansion/contraction unit 133 is operated, the third shielding unit 83 engaged with the first slide member is expanded leftward, and the second shielding unit 12 engaged with the second slide member is expanded leftward. , and the first and second slide members come into contact with the pair of side plates of the holder body, respectively. At this time, since the amount of expansion of the third shield unit 83 is greater than the amount of movement of the second shield unit 12, the middle gap 131c and the gap 131b at the other end of the shield unit group 131 can be closed or reduced at the same time. Further, when the expansion/contraction operation cord of the second expansion/contraction unit 52 is operated, the third shield unit 83 engaged with the first slide member is expanded in a direction approaching the right side frame portion 112a of the window frame 112, and the first slide member is extended. abut on the pair of side plates of the holder body. As a result, by operating the expansion/contraction operation cord of the second expansion/contraction unit 52, the gap 131a at one end of the shield unit group 131 can be closed or reduced. Unless the third extensible unit 133 attached to the adherend is operated, the third shield unit 83 cannot be elongated or contracted in its longitudinal direction. Since the two shielding units 12 cannot be moved in the longitudinal direction, the third shielding is performed while the middle gap 131c, the gap 131a at one end, and the gap 131b at the other end of the shielding unit group 131 are not closed or reduced. Even if the body unit 83 and the second shield unit 12 are operated up and down, the third shield unit 83 and the second shield unit 12 do not extend or move in the longitudinal direction, and the third shield unit 83 and the second shield unit 12 do not move. Unintended contact with the shield unit 12, unintended contact with the left frame portion 112b of the second shield unit 12, and unintended contact with the right frame portion 112a of the third shield unit 83 can be suppressed. Since operations other than the above are substantially the same as those of the fourth embodiment, repeated description will be omitted.
