Summary of the Invention

Problems to be Solved by the Invention

[0005] In the conventional pergola, the louvers are arranged at a predetermined interval in the horizontal direction by disposing plate materials oriented in the vertical direction, so as to prevent dust such as fallen leaves from accumulating. Therefore, there is a problem that solar radiation cannot be sufficiently blocked during the summer solstice when the solar altitude is high, and almost no shade is formed.

[0006] Therefore, the present invention aims to provide a pergola that prevents the accumulation of debris such as fallen leaves and can also provide ample shade even during the summer solstice. [Means for solving the problem]

[0007] The pergola of the present invention is a pergola comprising a frame provided on the top of a support column, with a plurality of wing sections installed horizontally at regular intervals, wherein each of the plurality of wing sections has a substantially vertical section extending substantially vertically, an upward sloping section extending diagonally upward from the upper end of the substantially vertical section, and a downward sloping section extending diagonally downward from the lower end of the substantially vertical section on the opposite side of the upward sloping section.

[0008] According to the pergola of the present invention, each of the multiple wing sections has a substantially vertical section extending substantially vertically, an upward sloping section extending diagonally upward from the upper end of the substantially vertical section, and a downward sloping section extending diagonally downward from the lower end of the substantially vertical section on the opposite side from the upward sloping section. This makes it possible to create a large amount of shade even when the spacing between the structures is widened, and widening the spacing prevents the accumulation of debris such as fallen leaves. In particular, debris that slides down the upper surface of the upward sloping section is accelerated by free-falling once in the substantially vertical section before reaching the downward sloping section, causing it to slide down the upper surface of the downward sloping section with force, thus preventing the accumulation of debris.

[0009] The pergola of the present invention preferably has mounting parts provided at both ends in the longitudinal direction of each of the multiple slat sections, for attaching the multiple slat sections to the frame in an angle-adjustable manner. This makes it possible to adjust the amount of shade cast by changing the angle according to the sun's altitude and installation direction at the installation location of the pergola of the present invention. [Effects of the Invention]

[0010] (1) According to the pergola of the present invention, it is possible to prevent the accumulation of debris such as fallen leaves and to create a lot of shade even on the summer solstice.

[0011] (2) Each of the multiple wing sections is provided at both ends in the longitudinal direction, and has mounting sections for attaching the multiple wing sections to the frame in an angle-adjustable manner, so that the angle can be changed according to the sun's altitude and the direction of installation at the pergola's installation location, thereby adjusting the amount of shade cast. [Brief explanation of the drawing]

[0012] [Figure 1] This is a plan view of a pergola in an embodiment of the present invention. [Figure 2] This is a cross-sectional view AA in Figure 1. [Figure 3] Figure 2 is an enlarged cross-sectional view of the wing section. [Figure 4] Figure 2 is an enlarged perspective view of the end of the wing plate section. [Figure 5] This is a magnified view of the mounting holes for the wing plates on the frame. [Figure 6] This is an explanatory diagram showing the wing section tilted at a 10° angle. [Figure 7] This is an explanatory diagram showing the wing section tilted at a 20° angle. [Figure 8] This figure compares the shade formed by the pergola in this embodiment and a conventional pergola. [Modes for carrying out the invention]

[0013] Figure 1 is a plan view of a pergola in an embodiment of the present invention, Figure 2 is a cross-sectional view of AA in Figure 1, Figure 3 is an enlarged cross-sectional view of the wing section in Figure 2, Figure 4 is an enlarged perspective view of the end of the wing section in Figure 2, and Figure 5 is an enlarged view of the mounting holes for the wing section in the frame.

[0014] As shown in FIGS. 1 and 2, the pergola 1 in the embodiment of the present invention includes four columns 2, a frame body 3 provided on the upper part of the columns 2, and a plurality of blade parts 4 horizontally installed at regular intervals with respect to the frame body 3. The column 2 is formed of, for example, a square timber made of recycled wood. The frame body 3 is formed by four aluminum alloy square timbers 30A erected on the columns 2, a strip plate 30B made of a steel plate installed between these four square timbers, and a strip plate 30C made of recycled wood covering the outside of the strip plate 30B.

[0015] As shown in FIGS. 3 and 4, the blade part 4 has a substantially vertical part 40 extending in a substantially vertical direction, an upper inclined part 41 extending obliquely upward from the upper end part 40A of the substantially vertical part 40, and a lower inclined part 42 extending obliquely downward on the opposite side of the upper inclined part 41 from the lower end part 40B of the substantially vertical part 40. Further, mounting parts 43 for attaching the blade part 4 to the frame body 3 are provided at both longitudinal ends of the blade part 4.

[0016] The substantially vertical part 40 is formed of a strip-shaped plate material long in the horizontal direction. The substantially vertical part 40 is, for example, a strip-shaped steel plate with a thickness of 3.2 mm and a width of 130 mm, and both ends in its width direction are bent 45° in opposite directions respectively. The upper inclined part 41 and the lower inclined part 42 are strip-shaped plate materials long in the horizontal direction. As the strip-shaped plate materials of the upper inclined part 41 and the lower inclined part 42, for example, an aluminum composite plate with a thickness of 2.3 mm and a width of 190 mm can be used.

[0017] The upper inclined portion 41, the lower inclined portion 42, and the substantially vertical portion 40 are fixed by bolts and nuts using a fixing bracket 44. The fixing bracket 44 is, for example, a steel plate with a thickness of about 2.3 mm and a width of 50 mm, and both ends in the length direction are bent 45° in opposite directions respectively. By fixing this fixing bracket 44 to the substantially vertical portion 40 and fixing the upper inclined portion 41 and the lower inclined portion 42 to both ends of the fixing bracket 44 bent 45° respectively, the upper inclined portion 41 and the lower inclined portion 42 are inclined 45° with respect to the substantially vertical portion respectively. That is, the upper inclined portion 41, the lower inclined portion 42, and the substantially vertical portion 40 are arranged in a V shape with an opening angle of 135° respectively.

[0018] The mounting portion 43 includes a mounting plate 45 in which two mounting holes 45A and 45B for fixing to the frame body 3 by bolts and nuts are formed. A fixing bracket 46 having the same shape as the fixing bracket 44 is welded to the mounting plate 45. The fixing bracket 46 is fixed to the ends of the substantially vertical portion 40, the upper inclined portion 41, and the lower inclined portion 42 by bolts and nuts. As shown in FIG. 3, the mounting hole 45A is formed at a position within the V-shaped range formed between the upper inclined portion 41 and the substantially vertical portion 40. The mounting hole 45B is formed at a position within the V-shaped range formed between the lower inclined portion 42 and the substantially vertical portion 40. Further, the mounting holes 45A and 45B are at positions symmetric with respect to the center of the substantially vertical portion 40.

[0019] On the other hand, as shown in FIG. 5, the frame body 3 to which the wing plate portion 4 is attached is provided with four mounting holes 31A, 31B, 32A, and 32B. The mounting plate 45 of the wing plate portion 4 is fixed to the mounting hole 31A or the mounting hole 32A of the frame body 3 by bolts and nuts in accordance with the mounting hole 45A. Further, the mounting hole 45B of the mounting plate 45 is fixed to the mounting hole 31B or the mounting hole 32B of the frame body 3 by bolts and nuts.

[0020] The mounting holes 31A and 31B of the frame 3 are positioned so that when the vane section 4 is fixed to these mounting holes 31A and 31B using the mounting holes 45A and 45B of the mounting plate 45, the approximately vertical section 40 is in the vertical direction, as shown in Figure 3. The mounting hole 32B is positioned so that when the vane section 4 is fixed to these mounting holes 31A and 32B using the mounting holes 45A and 45B of the mounting plate 45, the approximately vertical section 40 is inclined 10° from the vertical direction, as shown in Figure 6. The mounting hole 32A is positioned so that when the vane section 4 is fixed to these mounting holes 32A and 32B using the mounting holes 45A and 45B of the mounting plate 45, the approximately vertical section 40 is inclined 20° from the vertical direction, as shown in Figure 7.

[0021] In other words, the vane section 4 can be attached to the frame 3 in an angle-adjustable manner by selectively using the mounting holes 45A and 45B of the mounting plate 45 and the mounting holes 31A, 31B, 32A and 32B of the frame 3. In this embodiment, the spacing between the multiple vane sections 4 is 312 mm, but as shown in Figure 2, with the approximately vertical section 40 oriented vertically, sunlight does not pass through to the sun at an altitude of 79.79° during the summer solstice.

[0022] Thus, in this embodiment, the pergola 1 can form a lot of shade even if the spacing between the structures is widened. Widening the spacing prevents the accumulation of debris such as fallen leaves, and it is possible to form a lot of shade even on the summer solstice. In particular, debris that slides down the upper surface of the upward sloping section 41 is accelerated by free-falling once in the nearly vertical section 40 before reaching the downward sloping section 42, causing it to slide down the upper surface of the downward sloping section 42 with force, thus preventing the accumulation of debris.

[0023] Furthermore, in this embodiment, the pergola 1 has mounting parts 43 at both ends in the longitudinal direction of each of the multiple wing sections 4, which are used to attach the multiple wing sections 4 in an angle-adjustable manner. This allows the angle to be changed according to the sun's altitude and installation direction at the installation location of the pergola 1, thereby adjusting the amount of shade cast.

[0024] Figure 8 is a comparison of the shades formed by pergola 1 in this embodiment and a conventional pergola 100. The conventional pergola 100 is equipped with louvers made of vertically oriented boards arranged at predetermined intervals in the horizontal direction. Figure 8 shows pergola 1100 as viewed from due south.

[0025] As shown in Figure 8, in this embodiment, pergola 1 can provide sufficient shade from 9:00 to 15:00 even during the summer solstice when the sun is high in the sky, whereas in conventional pergola 100, many gaps in the louver panels are present in the shaded area throughout the day. However, there is almost no difference during the winter solstice when the sun is low in the sky. In other words, in this embodiment, pergola 1 can maintain shade throughout the year and prevent the accumulation of debris such as fallen leaves.

[0026] In this embodiment, the angle of the substantially vertical portion 40 can be adjusted by selecting from 0°, 10°, and 20° from the vertical direction. However, it is also possible to adjust the angle within the range of 0 to 20° by making, for example, the mounting holes 45A and 45B of the mounting plate 45 and the mounting holes 31A, 31B, 32A, and 32B of the frame 3 into elongated holes.

[0027] Furthermore, various materials can be used for each component of Pergola 1, including aluminum alloy, steel, stainless steel, plastic, and wood. [Industrial applicability]

[0028] The present invention is useful as a pergola installed in parks, gardens, etc., to block sunlight, and is particularly suitable as a pergola that prevents the accumulation of debris such as fallen leaves and can create a lot of shade even on the summer solstice. [Explanation of symbols]
