Summary of the Invention

Problems to be Solved by the Invention

[0005] When arranging a plurality of louver materials to intersect, the effect of a swing stopper can be obtained by connecting the intersection portions.

[0006] However, in the structure described in Patent Document 1 above, since holes have to be drilled at the intersections, there is a problem that the number of processing steps increases during manufacturing. Also, depending on the accuracy of the hole processing, it may be difficult to join the intersecting parts, and there is a risk that assembly may become impossible.

[0007] Therefore, an object of the present disclosure is to provide a louver mounting structure that can prevent the louver material from swaying while reducing the labor of processing and construction in a louver mounting structure in which a plurality of louver materials are arranged intersecting each other.

Means for Solving the Problems

[0008] A louver mounting structure according to an aspect of the present disclosure is a louver mounting structure including a plurality of long louver materials. When the front direction of the louver is the front and the opposite direction of the front is the rear, a first louver material and a second louver material arranged behind the first louver material are provided. The first louver material and the second louver material intersect in a front view, and a deflection prevention material is provided at the intersecting portion. The first louver material includes a first groove portion that is open with equal width along the longitudinal direction on the surface facing the rear. The deflection prevention material is attached to the first louver material using the first groove portion.

Effects of the Invention

[0009] According to the present disclosure, since a deflection prevention material is provided at the portion where the louver materials intersect, deflection can be prevented using the intersecting portion. Also, the first louver material includes a first groove portion that is open with equal width along the longitudinal direction on the surface facing the rear, and the deflection prevention material is attached to the first louver material using the first groove portion. That is, since the deflection prevention material can be attached using the first groove portion, there is no need to form holes in the louver material, and there is no labor for processing. Also, since the deflection prevention material can be attached at an arbitrary position along the longitudinal direction of the first louver material, construction is easy and the construction time can also be shortened.

Embodiments for Carrying Out the Invention

[0011] Embodiments of the present invention will be described with reference to the drawings. In the following description, the front direction of the louver A is defined as the front, and the direction opposite to the front is defined as the rear. Also, when the louver A is viewed from the front, the horizontal width direction is defined as the left-right direction, and the vertical height direction is defined as the up-down direction.

[0012] The louver A according to this embodiment is configured to include a plurality of long louver materials. The louver A is formed into a panel shape by arranging a plurality of long louver materials in an organized manner, and as shown in FIG. 1, it can be attached to the wall surface 91 of a structure 90 such as a building body. At this time, since the louver materials are arranged with intervals, the wall surface 91 is not completely covered. By attaching the louver A to the wall surface 91 of the structure 90, various effects can be obtained. For example, the design property of the building exterior can be improved, the window opening can be concealed to ensure privacy, and the direct sunlight on the wall surface 91 can be softened to improve the heat insulation performance. In this embodiment, a base material 92 (such as an angle material) is fixed to the structure 90, and the louver material is attached to this base material 92. Specifically, a plurality of louver materials are arranged and fixed along the longitudinal direction of the base material 92.

[0013] As shown in FIG. 1, in this louver A, the louver materials are arranged in two rows, front and rear. That is, in each of the two rows, the front row and the rear row, a plurality of louver materials are arranged in parallel with an arbitrary interval. In this embodiment, the louver material arranged in the front row is called the first louver material 10, and the louver material arranged in the rear row is called the second louver material 20. At least one of the first louver materials 10 and at least one of the second louver materials 20 are arranged so as to intersect in a front view. At least one anti-flexure material 30 is provided at at least one location of this intersection. In the drawing, only one anti-flexure material 30 is attached, but this is merely an example, and it goes without saying that the anti-flexure material 30 may be attached to all the louver materials.

[0014] The first louver material 10 and the second louver material 20 are prismatic as shown in FIG. 3 and the like, and are formed so as to have the same cross-section at any position in the longitudinal direction. The first louver material 10 and the second louver material 20 can be constituted by, for example, extruded profiles made of aluminum. Note that since the shape of the louver material according to the present embodiment is merely an example, the shapes of the first louver material 10 and the second louver material 20 may be changed.

[0015] The first louver material 10 includes a decorative portion 11 which is a portion visible as an appearance from the front (including the diagonal front). Further, it includes a rear surface 12 facing the rear (the wall surface 91 side). Unlike the decorative portion 11, this rear surface 12 is a portion not visible as an appearance from the front. Since the first louver material 10 according to the present embodiment is prismatic as shown in FIG. 3 and the like, the front surface 11a and the left and right side surfaces 11b are visible from the front side. In other words, in this first louver material 10, the front surface 11a and the left and right side surfaces 11b constitute the decorative portion 11.

[0016] The rear surface 12 of the first louver material 10 is formed substantially flat. As shown in FIG. 6, a first groove portion 13 which opens with a constant width along the longitudinal direction is formed in the rear surface 12 of the first louver material 10. This first groove portion 13 has a shape for attaching a deflection prevention material 30 described later. This first groove portion 13 may be formed over the entire length of the first louver material 10.

[0017] As shown in FIGS. 7 and 8(a), the first groove portion 13 is formed so as to notch the center of the rear surface 12 of the first louver material 10 in the width direction. A space in which a plate 41 described later can be arranged is formed at the back of the first groove portion 13. At the opening edge of the first groove portion 13, a bent piece 13a bent inward in an L shape is formed. The bent piece 13a projects slightly inside the first louver material 10.

[0018] This first louver material 10 is used in plurality to form louver A. A plurality of the first louver materials 10 are arranged side by side in the left - right direction so as to form one decorative surface. In each of the first louver materials 10, the vicinity of the upper end and the vicinity of the lower end are fixed to the base material 92. The fixing method of the first louver material 10 and the base material 92 is not particularly limited. For example, the first louver material 10 and the base material 92 may be fixed using the first groove portion 13.

[0019] In the present embodiment, the second louver material 20 is formed with the same cross - sectional shape as the first louver material 10. That is, the second louver material 20 includes a decorative portion 21 which is a portion visible as an appearance from the front (including the diagonal front). Also, it includes a rear surface 22 facing the rear (the wall surface 91 side). This rear surface 22, unlike the decorative portion 21, is a portion not visible as an appearance from the front. Since the second louver material 20 according to the present embodiment is prismatic as shown in FIG. 3 etc., the front surface 21a and the left - and - right side surfaces 21b are visible from the front side. In other words, in this second louver material 20, the front surface 21a and the left - and - right side surfaces 21b constitute the decorative portion 21.

[0020] The rear surface 22 of the second louver material 20 is formed substantially flat. As shown in FIG. 6, a second groove portion 23 which opens with a uniform width along the longitudinal direction is formed in the rear surface 22 of this second louver material 20. This second groove portion 23 is shaped for attaching a deflection prevention material 30 described later. This second groove portion 23 may be formed over the entire length of the second louver material 20.

[0021] As shown in FIGS. 7 and 8(b), the second groove portion 23 is formed so as to notch the center of the rear surface 22 of the second louver material 20 in the width direction. A space in which a plate 41 described later can be arranged is formed at the back of the second groove portion 23. At the opening edge of the second groove portion 23, a bent piece 23a bent inward in an L - shape is formed. The bent piece 23a projects slightly inside the second louver material 20.

[0022] This second louver material 20 is used in plurality to form the louver A. A plurality of the second louver materials 20 are arranged side by side in the left-right direction so as to form one decorative surface. In each of the second louver materials 20, the vicinity of the upper end portion and the vicinity of the lower end portion are fixed to the base material 92. The method of fixing the second louver material 20 to the base material 92 is not particularly limited. For example, the second louver material 20 and the base material 92 may be fixed using the second groove portion 23.

[0023] This second louver material 20 is disposed behind the first louver material 10. For this reason, the decorative surface formed by the plurality of second louver materials 20 is disposed behind the decorative surface formed by the plurality of first louver materials 10. By overlapping the two decorative surfaces in the front-rear direction in this way, the design property can be enhanced.

[0024] Note that it is desirable that the rear surface 12 of the first louver material 10 described above be parallel to the wall surface 91. Similarly, it is desirable that the rear surface 22 of the second louver material 20 described above be parallel to the wall surface 91. Further, it is desirable that the rear surface 12 of the first louver material 10 and the rear surface 22 of the second louver material 20 be parallel to each other.

[0025] The anti-flexure material 30 is for preventing the first louver material 10 and the second louver material 20 from flexing. By using this anti-flexure material 30, both the first louver material 10 and the second louver material 20 made of long members can be prevented from swaying. The anti-flexure material 30 according to the present embodiment is a bent plate-shaped metal fitting as shown in FIG. 9. This anti-flexure material 30 can be created by bending a single sheet metal. This anti-flexure material 30 includes a first attachment portion 31, a second attachment portion 32, and an intermediate portion 33.

[0026] The first attachment part 31 is a part for attaching to the first louver material 10. The first attachment part 31 is a flat plate-shaped part. The first attachment part 31 according to the present embodiment can be attached to the first groove part 13 of the first louver material 10. A substantially U-shaped first cutout hole 31a is formed in this first attachment part 31. In addition, this first attachment part 31 is formed in a semi-circular shape in order to make it difficult to visually recognize when viewed from the front. For this reason, as shown in FIG. 6, even when the first attachment part 31 is attached to the first louver material 10 in an inclined state, the first attachment part 31 does not protrude from the visible width of the first louver material 10.

[0027] The second attachment part 32 is a part for attaching to the second louver material 20. The second attachment part 31 is a flat plate-shaped part. The second attachment part 32 according to the present embodiment can be attached to the second groove part 23 of the second louver material 20. A substantially U-shaped second cutout hole 32a is formed in this second attachment part 32.

[0028] The intermediate part 33 is a part provided between the first attachment part 31 and the second attachment part 32, and connects the first attachment part 31 and the second attachment part 32. The above-described first attachment part 31 and second attachment part 32 are formed by bending the ends of the intermediate part 33. In the present embodiment, the intermediate part 33 and the first attachment part 31 are connected at a right angle. Also, the intermediate part 33 and the second attachment part 32 are connected at a right angle. Note that the first attachment part 31 and the second attachment part 32 are formed parallel to each other, but extend from the intermediate part 33 in opposite directions (for example, in FIG. 7, the first attachment part 31 extends downward in FIG. 7, while the second attachment part 32 extends upward in FIG. 7).

[0029] A right-angled first inner corner portion 33a is formed between the middle portion 33 and the first attachment portion 31. Also, a right-angled second inner corner portion 33b is formed between the middle portion 33 and the second attachment portion 32. The first inner corner portion 33a and the second inner corner portion 33b are formed on different surfaces of the middle portion 33, respectively. Further, as shown in FIGS. 7 and 8(b), the second inner corner portion 33b can be engaged with a corner (the corner at the boundary between the decorative portion 21 and the rear surface 22) of the second louver material 20. Therefore, when the anti-flexure member 30 is attached to the second louver material 20, it can be easily positioned, and the state after attachment is also stabilized.

[0030] Note that when the second inner corner portion 33b is engaged with the corner of the second louver material 20 in this way, as shown in FIG. 6, the longitudinal direction of the second groove portion 23 and the opening direction of the second notch hole 32a are in the same direction. In this state, the second groove portion 23 and the second notch hole 32a can be connected by a connecting member 40, which will be described later.

[0031] Also, the opening direction of the first notch hole 31a and the opening direction of the second notch hole 32a are formed to be different. Specifically, when it is assumed that the first attachment portion 31 and the second attachment portion 32 are in the same plane (when it is assumed that the first attachment portion 31 and the second attachment portion 32 are overlapped), the opening directions of the first notch hole 31a and the second notch hole 32a are formed to be orthogonal to each other.

[0032] One end portion (the first attachment portion 31) of this anti-flexure member 30 is attached to the first louver material 10 using the first groove portion 13, and the other end portion (the second attachment portion 32) is attached to the second louver material 20 using the second groove portion 23. When attaching the anti-flexure member 30 to the first groove portion 13 or the second groove portion 23, a connecting member 40 as shown in FIGS. 6 to 8 is used. The connecting member 40 according to the present embodiment includes a plate 41 formed with a female screw and a bolt 42 screwed into the female screw of the plate 41.

[0033] The plate 41 is a plate-like member attached to the hollow portion of the louver material. This plate 41 includes a central thick portion 41a and thin portions 41b provided on both sides of the thick portion 41a. The thick portion 41a is formed thicker than the thin portions 41b, and a female screw is formed to penetrate through the center. The width of the thick portion 41a is set to be slightly smaller than the widths of the first groove portion 13 and the second groove portion 23 so that it can be fitted into the first groove portion 13 and the second groove portion 23. Also, a step 41c is formed at the boundary between the thick portion 41a and the thin portions 41b. As shown in FIGS. 8(a) and 8(b), this plate 41 is used by abutting against the first groove portion 13 or the second groove portion 23 from the back side. At this time, the thick portion 41a is adapted to fit into the first groove portion 13 or the second groove portion 23, and the positioning in the width direction of the plate 41 can be easily performed. And the plate 41 can also be slid along the longitudinal direction of the first groove portion 13 or the second groove portion 23. Also, the refraction pieces 13a, 23a are engaged with the step 41c to prevent the rotation of the plate 41, and the rotation of the plate 41 when the bolt 42 is tightened can be prevented.

[0034] As the bolt 42, a general one can be used, and it includes a head portion 42a and a shaft portion 42b. A male screw that screws into the female screw formed in the plate 41 is cut on the shaft portion 42b. This shaft portion 42b is fastened to the plate 41 attached to the hollow portion of the louver material in a state of being engaged with the first notch hole 31a of the first attachment portion 31 or the second notch hole 32a of the second attachment portion 32. Thereby, the connecting member 40 can connect the first attachment portion 31 (the first notch hole 31a) and the first groove portion 13, and can also connect the second attachment portion 32 (the second notch hole 32a) and the second groove portion 23.

[0035] When connecting the first attachment part 31 and the first groove part 13, as shown in Fig. 8(a), set the plate 41 on the back side of the first groove part 13, and set the first attachment part 31 from the outside of the first groove part 13 so as to overlap this plate 41. As a result, the rear surface 12 of the first louver material 10 is sandwiched between the plate 41 and the first attachment part 31. Then, fasten the bolt 42 attached so as to penetrate the first notch hole 31a to the female screw of the plate 41. Thereby, the first attachment part 31 of the anti-flexure material 30 and the first groove part 13 of the first louver material 10 can be connected. Note that the plate 41 does not have to be a female screw, and the plate side may be a male screw. Specifically, a bolt may be fixed to the plate by welding or the like, the head of the bolt may be inserted into the groove part, and the rear surface 12 of the first louver material 10 may be sandwiched and fastened with the shaft part of the bolt and a nut.

[0036] Also, when connecting the second attachment part 32 and the second groove part 23, as shown in Fig. 8(b), set the plate 41 on the back side of the second groove part 23, and set the second attachment part 32 from the outside of the second groove part 23 so as to overlap this plate 41. As a result, the rear surface 22 of the second louver material 20 is sandwiched between the plate 41 and the second attachment part 32. Then, fasten the bolt 42 attached so as to penetrate the second notch hole 32a to the female screw of the plate 41. Thereby, the second attachment part 32 of the anti-flexure material 30 and the second groove part 23 of the second louver material 20 can be connected.

[0037] By connecting both ends of the anti-flexure material 30 to the first louver material 10 and the second louver material 20 in this way, the first louver material 10 and the second louver material 20 can be connected by the anti-flexure material 30. At this time, as shown in Fig. 6, since the second inner corner part 33b engages with the corner of the second louver material 20, the second attachment part 32 and the second louver material 20 are fixed in a state where their longitudinal directions are orthogonal to each other. On the other hand, the first attachment part 31 and the first louver material 10 can be connected at a free angle with respect to their longitudinal directions. Therefore, no matter what the inclination of the first louver material 10 and the second louver material 20 is, they can be connected by the same anti-flexure material 30.

[0038] Also, as shown in FIG. 5, since the first attachment portion 31 is attached to the rear surface 12 of the first louver material 10 and the second attachment portion 32 is attached to the rear surface 22 of the second louver material 20, the anti-flexure material 30 is not conspicuous. Therefore, as shown in FIG. 2, the anti-flexure material 30 is hardly visible in a front view, and the design property is good.

[0039] Also, as shown in FIGS. 3 and 4, the anti-flexure material 30 can connect the first louver material 10 and the second louver material 20 in a state where they are arranged at intervals in the front-rear direction. Therefore, a three-dimensional effect is created by the overlap between the first louver material 10 and the second louver material 20, and the design property can be improved. When it is desired to change the interval in the front-rear direction between the first louver material 10 and the second louver material 20, the length of the intermediate portion 33 of the anti-flexure material 30 may be changed.

[0040] Note that, as shown in FIG. 6(b), the anti-flexure material 30 may be attached to the side surface 21b of the second louver material 20 by a fixture 45 such as a screw. By fixing with the fixture 45 in this way, the attachment state of the anti-flexure material 30 becomes more stable. When using the fixture 45, as shown in FIG. 9, a fixture hole 33c through which the fixture 45 penetrates may be formed through the intermediate portion 33 of the anti-flexure material 30.

[0041] As described above, according to the present embodiment, since the anti-flexure material 30 is provided at the portion where the louver materials intersect, it is possible to prevent flexure by utilizing the intersection portion. Further, the first louver material 10 includes a first groove portion 13 that opens with a constant width along the longitudinal direction on the rear surface 12, and the anti-flexure material 30 is attached to the first louver material 10 by utilizing the first groove portion 13. That is, since the anti-flexure material 30 can be attached by utilizing the first groove portion 13, it is not necessary to form holes in the louver material, and there is no labor for processing. Further, since the anti-flexure material 30 can be attached at an arbitrary position along the longitudinal direction of the first louver material 10, the construction is easy and the construction time can also be shortened.

[0042] Further, the second louver member 20 is provided with a second groove portion 23 that opens with a constant width along the longitudinal direction on the rear surface 22, and the anti-flexure member 30 is attached to the second louver member 20 using the second groove portion 23. That is, since the anti-flexure member 30 can be attached to an arbitrary position using the second groove portion 23, there is no need to form holes in the louver member, and there is no labor for processing. Further, since it is attached at an arbitrary position along the longitudinal direction of the second louver member 20, the construction is easy and the construction time can also be shortened. Further, since the anti-flexure member 30 can prevent the flexure of the first louver member 10 and the second louver member 20 simultaneously, anti-vibration can be performed with a small number of parts.

[0043] Further, since the anti-flexure member 30 is attached using the groove portion, the attachment position of the anti-flexure member 30 can be freely set. For example, as shown in FIG. 1, even when the intersecting position (height) of the louver members or the intersecting angle of the louver members is different, the anti-flexure member 30 can be attached without additional hole processing.

[0044] Further, since the groove portion is formed on the rearward-facing surface (the surface facing the wall surface 91 of the structure 90), the groove portion and the anti-flexure member 30 are not conspicuous, and a neat design can be realized.

[0045] Further, the anti-flexure member 30 includes a first attachment portion 31 attached to the first groove portion 13, a second attachment portion 32 attached to the second groove portion 23, and an intermediate portion 33 connecting the first attachment portion 31 and the second attachment portion 32, and the first attachment portion 31 and the second attachment portion 32 are formed by bending the ends of the intermediate portion 33. According to such a configuration, it can be manufactured at low cost while maintaining the strength of the anti-flexure member 30.

[0046] Further, a second inner corner portion 33b formed by the second attachment portion 32 and the intermediate portion 33 is configured to engage with the corner of the second louver member 20. According to such a configuration, since the engagement between the anti-flexure member 30 and the louver member is stabilized, the effect of preventing rattling of the louver member can be enhanced.

[0047] Further, a substantially U-shaped second notch hole 32a is formed in the second attachment portion 32, and the second groove portion 23 and the second notch hole 32a can be connected by a connecting member 40 so that the longitudinal direction of the second groove portion 23 and the opening direction of the second notch hole 32a are the same direction. According to such a configuration, since the second attachment portion 32 can be slid along the second groove portion 23 to adjust the attachment position, the workability is good.

[0048] Note that, regarding the anti-bending member 30 of the above embodiment, an example in which the first corner portion 33a and the second corner portion 33b are at right angles has been described, but the angles of the first corner portion 33a and the second corner portion 33b do not have to be right angles. For example, in the anti-bending member 50 shown in FIGS. 10 and 11, the angles of the first corner portion 33a and the second corner portion 33b are set to 45 degrees. The bending of the first louver member 10 and the second louver member 20 may be prevented by using such an anti-bending member 50. Even when the angle of the second corner portion 33b is changed, the anti-sway effect can be enhanced by engaging the second corner portion 33b with the corner of the second louver member 20. In other words, the same effect can be achieved by forming the second corner portion 33b at the same angle as the angle formed by the side surface 21b and the rear surface 22 of the second louver member 20. Further, although the anti-bending members 30 and 50 of the above embodiment are attached to the rear surface 22 of the second louver member 20, other modes may be adopted.

[0049] For example, an anti-bending member 60 as shown in FIGS. 12 and 13 may be used. The anti-bending member 60 according to this modification is formed in a U-shape in plan view and includes a first attachment portion 61 and a second attachment portion 62. The first attachment portion 61 is a portion for attaching to the first louver member 10. The first attachment portion 61 is attached to the first groove portion 13 of the first louver member 10 by a connecting member 40. The second attachment portion 62 is a portion for attaching to the second louver member 20. The second attachment portion 62 is attached to the side surface 21b of the second louver member 20 by a fixture 45. The bending of the first louver member 10 and the second louver member 20 may be prevented by using such an anti-bending member 60.

[0050] Alternatively, a bending prevention member 70 as shown in FIG. 14 may be used. The bending prevention member 70 according to this modification is formed in an L shape in plan view and includes a first attachment portion 71 and a second attachment portion 72. The first attachment portion 71 is a portion for attaching to the first louver member 10, and a substantially U-shaped first notch hole 71a is formed therein. The first attachment portion 71 is attached to the first groove portion 13 of the first louver member 10 by a connecting member 40. Further, the second attachment portion 72 is a portion for attaching to the second louver member 20.
