  When attaching the solar shading device to a structure using the mounting aid described in Patent Document 1, first fix the mounting aid to the structure with a screw, and then stack the bracket of the solar shading device on the mounting aid. The bracket was fixed with a screw in the screw hole of the mounting aid. For this reason, there has been a problem that the fixing work using a fixing tool such as a screw increases and the installation work of the solar shading device becomes complicated.

  It is an object of the present invention to provide an auxiliary member for a solar shading device that solves the above-described problems and can improve the workability of the mounting operation of the solar shading device.

  In order to solve the above-mentioned problem, the present invention is an auxiliary member of a solar radiation shielding device installed between a bracket of a solar radiation shielding device and a mounting surface of a structure, and has an engaging portion that engages with the bracket. It is characterized by that.

  According to such a structure, since the auxiliary member of the solar radiation shielding apparatus has the engaging part engaged with the bracket, the auxiliary member can be engaged with the bracket in advance by the engaging part. Therefore, a fixture such as a screw for attaching the auxiliary member to the attachment surface is not necessary. Moreover, when fixing a bracket and an auxiliary member to an attachment surface simultaneously, since an operator only needs to hold | maintain either one, workability | operativity improves. Further, during the fixing work, the position shift between the bracket and the auxiliary member can be suppressed by the engaging portion. As a result, it is possible to improve the workability of the solar shading device mounting work.

  Moreover, it is preferable that the engaging portion is configured to engage the bracket with a snap fit.

  According to such a structure, since an engaging part engages with a bracket by a snap fit, an auxiliary member can be easily engaged with a bracket without using a jig or a tool.

  Moreover, it is preferable that the engaging portion is configured to sandwich the bracket from both sides.

  According to such a structure, since the engaging part becomes a structure which clamps a bracket from both sides, it can engage a bracket and an auxiliary member reliably.

  Further, the auxiliary member of the solar radiation shielding device can have a plurality of auxiliary members stacked on top of each other, and has an engaged portion that is engaged with an engaging portion of another auxiliary member that is adjacently stacked. Is preferred.

  According to such a configuration, for example, even when the protrusion amount of the obstacle with respect to the mounting surface is large and interference between the solar radiation shielding device and the obstacle cannot be avoided with one auxiliary member, the plurality of auxiliary members are used to overlap each other. Thus, interference between the solar radiation shielding device and the obstacle can be avoided. Furthermore, since the auxiliary member has an engaged portion that is engaged with an engaging portion of another auxiliary member that is adjacently stacked, a fixing tool such as a screw for attaching the other auxiliary member to the attachment surface is provided. It becomes unnecessary. Moreover, when fixing a some auxiliary member and a bracket to an attachment surface simultaneously, since an operator only needs to hold | maintain any one, workability | operativity improves. In addition, during the fixing operation, the displacement between the plurality of auxiliary members and the bracket can be suppressed by the engaging portion and the engaged portion. As a result, it is possible to improve the workability of the solar shading device mounting work.

  In addition, the engaged portion is in a position where the other auxiliary member can be engaged with the engaging portion of the other auxiliary member in a state where the other auxiliary member is relatively rotated by 180 degrees around an axis perpendicular to the mounting surface. It is preferable to provide the configuration.

  According to such a configuration, a plurality of auxiliary members having the same shape can be rotated relative to each other by 180 degrees and overlapped with each other. Therefore, it is not necessary to manufacture many types of auxiliary members, and the number of molds and the number of parts can be reduced.

  Moreover, the auxiliary member of the solar shading device according to the present invention includes an end engaging portion that extends from an end of the auxiliary member and engages with an end of the bracket by a snap fit, and the end engaging portion. An end engaged portion that is provided at an end of the auxiliary member on the opposite side and is engaged with an end engaging portion of another adjacent auxiliary member when a plurality of the auxiliary members are installed in a stacked manner It is preferable to have a configuration including:

  According to such a configuration, since the auxiliary member has the end engaging portion and the end engaged portion, the end of the auxiliary member is reliably engaged with the end of the bracket or other auxiliary member. be able to. Therefore, it is possible to further suppress the detachment or misalignment between the auxiliary member and the bracket, or the detachment or misalignment between the auxiliary member and another auxiliary member.

The window frame 42 protrudes by a protrusion amount X from the mounting surface 4a.
The attachment surface 4a is not limited to the indoor side surface of the wall body 41, and may be, for example, a ceiling surface or a window frame itself.

  The solar radiation shielding device 2 is a device that shields solar radiation by covering the window 4b. The solar radiation shielding device 2 mainly includes a bracket 3 fixed to the mounting surface 4a, a head box 21 supported by the bracket 3, and a shielding member 22 suspended from the head box 21.

  The head box 21 is a box-like member that houses lifting means and tilting means (not shown) of the shielding material 22 and extends along the width direction (left-right direction) of the window 4b. The head box 21 is detachably fixed to the bracket 3. At the upper corner of the head box 21 and at the corners on the indoor side and the corners on the outdoor side, hook-shaped hooked portions 21a and 21b that are hooked on the bracket 3 are respectively provided.

The shielding material 22 is a horizontal blind provided with a plurality of slats 22a, for example. The shielding member 22 opens and closes in the vertical direction by winding and rewinding the lifting / lowering cord 22b by lifting / lowering means (not shown). The shielding member 22 is tilted by driving the ladder cord 22c by a tilting means (not shown), and opens and closes the gap between the slats 22a. The separation distance Y from the mounting surface 4a to the shielding member 22 is adjusted by the auxiliary member 1 so as to be larger than the protrusion amount X of the window frame 42 (Y> X).
The shielding member 22 is not limited to a horizontal blind, and may be a pleated screen, a scooping curtain, a roll screen, or the like.

  As shown in FIGS. 1 and 2, the bracket 3 is a metal member formed in an inverted L shape in a side view. The bracket 3 has a vertical portion 31 extending in the vertical direction and a horizontal portion 32 extending from the upper end of the vertical portion 31 to the indoor side.

  The vertical portion 31 is a portion that is fixed to the mounting surface 4 a via the auxiliary member 1. The vertical portion 31 has a pair of side flanges 31a extending from both side portions in the width direction to the indoor side. The vertical portion 31 is formed with a through hole 31b for inserting a screw N (see FIG. 1). An elastic body 31c made of sponge, soft rubber or the like is installed on the lower end side of the vertical portion 31. The elastic body 31c functions as a non-slip means that suppresses rattling or slipping of the head box 21 with respect to the bracket 3.

  The horizontal part 32 is a part that supports the head box 21. The horizontal portion 32 has a pair of upper flanges 32a that fall from both sides in the horizontal direction. The upper flange 32a is formed with a hook-like hooking portion 32b for hooking the hooked portion 21a on the indoor side of the head box 21.

  A slide mechanism 32c that slides along the horizontal portion 32 is provided between the upper flanges 32a. On the outdoor side of the slide mechanism 32c (on the mounting surface 4a side), a hook-shaped hooking portion 32d for hooking the hooked portion 21b on the outdoor side of the head box 21 is provided. The slide mechanism 32c (that is, the latching portion 32d) is biased toward the indoor side (the latched portion 21b side) by a biasing means (not shown). By fitting the latched portion 21b into the latching portion 32d from the lower side against the urging force of the urging means, the slide mechanism 32c slides, and the latched portion 21b elastically engages with the latching portion 32d. It is hooked.

  Note that the shape and structure of the bracket 3 is not limited to this, and may be anything. For example, the bracket 3 may be formed in an I shape in a side view, and the outdoor side surface of the head box 21 may be supported.

  As shown in FIGS. 1, 2, and 3, the auxiliary member 1 is a member installed between the mounting surface 4 a and the bracket 3, and is formed of, for example, a resin material. The auxiliary member 1 has a function of adjusting the separation distance Y from the mounting surface 4 a to the shielding material 22. The auxiliary member 1 is engaged with the vertical portion 31 of the bracket 3. The auxiliary member 1 includes a main body 11, a pair of engaging portions 12 and end engaging portions 13 extending from the main body 11, and a pair of engaged portions 14 and end portions recessed in the main body 11. And the engaged portion 15.

  The main body 11 is a block-shaped part having a substantially rectangular parallelepiped shape elongated in the vertical direction. The main body 11 is sandwiched between the mounting surface 4 a and the bracket 3. The main body 11 has two oval (elliptical) through holes 11a. The two through holes 11a are holes through which the screws N are inserted, and are arranged side by side at the center in the width direction. Moreover, the main-body part 11 has the some hollow part 11b for weight reduction, and the some rib 11c for rigidity reinforcement.

  The pair of engaging portions 12 are plate-like portions extending from both side portions in the width direction of the main body portion 11 to the indoor side, and have a function of engaging with the vertical portion 31 of the bracket 3. The space | interval of a pair of engaging part 12 substantially corresponds to the dimension of the width direction of the bracket 3 (refer FIG.3 (c)). At the tips of the pair of engaging portions 12, claw portions 12a projecting inward are formed. A distance H1 from the surface on the indoor side of the main body portion 11 to the claw portion 12a substantially coincides with the height dimension H2 of the side flange 31a (H1 = H2: see FIG. 3C).

  The pair of engaging portions 12 are engaged with the bracket 3 by snap fit. Specifically, the indoor side surface of the claw portion 12a is inclined so as to be positioned closer to the main body portion 11 as it goes inward. Therefore, when the pair of engaging portions 12 are pressed against the vertical portion 31 of the bracket 3 from the outdoor side, the pair of engaging portions 12 are elastically deformed and spread by the inclined surfaces of the claw portions 12a. The vertical portion 31 enters between 12 (between the claw portions 12a). And if the nail | claw part 12a exceeds the side part flange 31a, a pair of engaging part 12 will return to an original state. Thereby, while a pair of engaging part 12 clamps the vertical part 31 from the both sides of the width direction, the nail | claw part 12a engages with the front-end | tip of the side part flange 31a, and the auxiliary member 1 engages with the bracket 3 by a snap fit. It will be in the state.

  The end engaging portion 13 is a plate-like portion extending from the one end portion (the lower end portion in the first embodiment) in the vertical direction of the main body portion 11 to the indoor side. A claw portion 13 a that protrudes toward the other end portion is formed at the tip of the end portion engaging portion 13. An interval T1 from the room-side surface of the main body 11 to the claw portion 13a substantially matches the plate thickness dimension T2 of the vertical portion 31 (T1 = T2: see FIGS. 3B and 3C). Similarly to the engaging portion 12, the end engaging portion 13 is engaged with the bracket 3 by snap fit.

  A pair of engaged portions 14 and end engaged portions 15 are a pair of engaging portions 12 and end engaging portions of other auxiliary members 1 that are overlapped when a plurality of auxiliary members 1 are used. 13 is a part to be engaged. The pair of engaged portions 14 and the end engaged portion 15 will be described in detail with reference to FIGS. 3 and 4 in the second embodiment.

  When the bracket 3 is fixed to the mounting surface 4a via the auxiliary member 1, first, the auxiliary member 1 is engaged with the bracket 3 by snap fit. Next, the bracket 3 engaged with the auxiliary member 1 is arranged at a predetermined position on the mounting surface 4a. At this time, the operator may support at least one of the auxiliary member 1 and the bracket 3. Then, a screw N (see FIG. 1) is inserted into the through hole 31b of the bracket 3 and the through hole 11a of the auxiliary member 1, and the screw N is screwed to the mounting surface 4a using a tool such as an electric screwdriver. Thereby, the fixing operation of the bracket 3 is completed.

  Since the auxiliary member 1 configured as described above has the pair of engaging portions 12 that engage with the bracket 3, the auxiliary member 1 can be engaged with the bracket 3 in advance by the pair of engaging portions 12. . This eliminates the need for a fixture for attaching the auxiliary member 1 prior to the attachment surface 4a. Further, when the bracket 3 and the auxiliary member 1 are simultaneously fixed to the mounting surface 4a with the screw N, the operator only needs to hold one of them, so that workability is improved. Further, the positional displacement between the bracket 3 and the auxiliary member 1 can be suppressed by the pair of engaging portions 12 during the fixing work. As a result, the workability of the installation work of the solar shading device 2 can be improved.

  Moreover, since a pair of engaging part 12 engages with the bracket 3 by a snap fit, the auxiliary member 1 can be easily engaged with the bracket 3 without using a jig or a tool. Further, since the pair of engaging portions 12 are configured to sandwich the bracket 3 from both sides in the width direction, the bracket 3 and the auxiliary member 1 can be reliably engaged.

  Further, since the auxiliary member 1 has the end engaging portion 13 that engages with the end of the bracket 3, the auxiliary member 1 engages with the bracket 3 from three directions. Therefore, the bracket 3 and the auxiliary member 1 can be more reliably engaged.

  Next, the auxiliary member of the solar shading device according to the second embodiment will be described in detail with reference to FIGS. 3 and 4 (mainly FIG. 4). In addition, the same code | symbol is attached | subjected to the element same as 1st Embodiment, and the overlapping description is abbreviate | omitted.

  As shown in FIGS. 4A and 4B, a plurality (two in the second embodiment) of auxiliary members 1 according to the second embodiment are installed in an overlapping manner. For convenience of explanation, the auxiliary member 1 that engages with the bracket 3 is referred to as a first auxiliary member 1A, and the auxiliary member 1 that is installed on the first auxiliary member 1A is referred to as a second auxiliary member 1B. The second auxiliary member 1B has the same structure as the first auxiliary member 1A, but is in an upside down (180 degree relative rotation) with respect to the first auxiliary member 1A. Hereinafter, the pair of engaged portions 14 and the end engaged portion 15 will be described in detail, and the description of the other parts is omitted since it is the same as in the first embodiment.

  The first auxiliary member 1A is engaged with a pair of engaged portions 14 that are engaged with a pair of engaging portions 12 of the second auxiliary member 1B, and an end engaging portion 13 of the second auxiliary member 1B. And an end engaged portion 15 (see FIG. 3).

  As shown in FIGS. 3 and 4, the pair of engaged portions 14 are recessed portions that are recessed in the side surface of the main body portion 11 in the width direction. An interval H3 from the outdoor surface of the main body 11 to the engaged portion 14 is an interval H1 from the indoor surface of the main body 11 to the claw portion 12a (that is, the height dimension H2 of the side flange 31a of the bracket 3). ) (H3 = H1 = H2: see FIG. 4A). In addition, the pair of engaged portions 14 are 180-degree rotationally symmetric with respect to the pair of engaging portions 12 around an axis C (see FIG. 3) that passes through the center of the main body 11 and is perpendicular to the mounting surface 4a. Is formed.

  The end portion engaged portion 15 is a concave portion provided in the upper end portion of the main body portion 11 (the end portion on the side opposite to the end portion engaging portion 13). The interval T3 from the indoor side surface of the main body 11 to the end engaged portion 15 is the interval T1 from the indoor side surface of the main body 11 to the claw portion 13a (that is, the plate thickness dimension of the vertical portion 31 of the bracket 3). (T3 = T1 = T2: see FIGS. 3B and 3C).

  The pair of engaging portions 12 of the second auxiliary member 1B are engaged not with the bracket 3 but with the pair of engaged portions 14 of the first auxiliary member 1A. Further, the end engaging portion 13 of the second auxiliary member 1B is engaged not with the bracket 3 but with the end engaged portion 15 of the first auxiliary member 1A.

  When the second auxiliary member 1B is engaged with the first auxiliary member 1A, first, as shown in FIG. 4A, the second auxiliary member 1B is rotated 180 around the axis C with respect to the first auxiliary member 1A. Rotate relative to make it upside down. Thereby, a pair of engaging part 12 of the 2nd auxiliary member 1B will be in the state arranged at a position corresponding to a pair of engaged parts 14 of the 1st auxiliary member 1A. In addition, the end engaging portion 13 of the second auxiliary member 1B is disposed at a position corresponding to the end engaged portion 15 of the first auxiliary member 1A.

  Next, the second auxiliary member 1B in this state is pushed toward the first auxiliary member 1A. Thereby, as shown in FIG.4 (b), a pair of engaging part 12 of 2nd auxiliary member 1B engages with a pair of to-be-engaged part 14 of 1 A auxiliary member 1A by a snap fit. Further, the end engaging portion 13 of the second auxiliary member 1B is engaged with the end engaged portion 15 of the first auxiliary member 1A by snap fitting.

  Next, the effect of the auxiliary member 1 (1st auxiliary member 1A and 2nd auxiliary member 1B) of the solar radiation shielding apparatus which concerns on 2nd Embodiment is demonstrated.

For example, when the projection amount X of the window frame 42 (see FIG. 1) is large and the shielding member 22 interferes with the window frame 42 with only one auxiliary member 1, the first auxiliary member 1A and the second auxiliary member 1B. By overlapping and installing, the interference between the shielding material 22 and the window frame 42 may be avoided.
At this time, according to the auxiliary member 1 (the first auxiliary member 1A and the second auxiliary member 1B) of the solar radiation shielding device according to the second embodiment, the first auxiliary member 1A is adjacently overlapped with the second auxiliary member. Since it has a pair of to-be-engaged part 14 engaged with a pair of engaging part 12 of 1B, the 2nd auxiliary member 1B will be in the state engaged with 1A of 1st auxiliary members. The first auxiliary member 1 </ b> A is engaged with the bracket 3. Therefore, a screw or the like for attaching the first auxiliary member 1A and the second auxiliary member 1B prior to the attachment surface 4a becomes unnecessary. Moreover, since the operator who attaches these to the attachment surface 4a should just hold | maintain any one of the bracket 3, the 1st auxiliary member 1A, and the 2nd auxiliary member 1B, workability | operativity improves. Further, during the fixing operation, the displacement of the bracket 3, the first auxiliary member 1A, and the second auxiliary member 1B can be suppressed by the respective engaging portions 12. As a result, the workability of the installation work of the solar shading device 2 can be improved.

  Further, the pair of engaged portions 14 of the first auxiliary member 1A is a pair of the second auxiliary member 1B in a state where the second auxiliary member 1B is relatively rotated by 180 degrees around the axis C perpendicular to the mounting surface 4a. Since it is provided at a position where it can be engaged with the engaging portion 12, the two auxiliary members 1 having the same shape can be rotated 180 degrees relative to each other and placed on top of each other. Therefore, it is not necessary to manufacture many kinds of auxiliary members 1, and the number of molds and the number of parts can be reduced.

  The first auxiliary member 1 </ b> A extends from the lower end portion of the main body portion 11, engages with the lower end portion of the bracket 31 by snap fit, and the main body on the side opposite to the end engaging portion 13. And an end engaged portion 15 provided at the upper end of the portion 11 and engaged with the end engaging portion 13 of the second auxiliary member 1B. When the auxiliary member 1B is rotated 180 degrees, the end engaging portion 13 of the second auxiliary member 1B can be engaged with the end engaged portion 15 of the first auxiliary member 1A. Therefore, it is possible to further suppress the detachment and displacement of the first auxiliary member 1A and the second auxiliary member 1B.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention.

  For example, in the second embodiment, the first auxiliary member 1A and the second auxiliary member 1B configured in the same shape are overlapped by rotating relative to each other by 180 degrees, but the present invention is not limited to this. For example, although the number of molds and the number of parts increase, two types of auxiliary members that can be engaged with each other are prepared, and these may be alternately stacked.

  Moreover, in this embodiment, although the to-be-engaged part 14 was recessedly provided in the side surface of the main-body part 11, this invention is not limited to this. For example, if the distance H1 (see FIG. 4) from the surface on the indoor side of the main body portion 11 to the claw portion 12a of the engaging portion 12 is the same as the thickness dimension of the main body portion 11, The claw portion 12a can be locked to the surface (that is, the indoor side surface of the main body 11 can be used as the engaged portion 14).

  Moreover, in this embodiment, although it was set as the structure which engages both the pair of engaging parts 12 with the bracket 3 by a snap fit, this invention is not limited to this. For example, first, one engaging portion 12 is engaged with the bracket 3 by an engaging means that is not snap-fit, and then the auxiliary member 1 is rotated with the one engaging portion 12 as a fulcrum while the other engaging portion 12 is engaged. The joint portion 12 may be engaged with the bracket 3 by snap fitting.
