Description

[Technical field]

[0001] The present invention relates to a pergola that is installed in parks, gardens, etc. to provide protection from sunlight. [Background technology]

[0002] Pergolas, which are installed in parks, gardens, etc. to protect against sunlight, are generally composed of upright posts and beams attached to the tops of the posts. For example, Patent Document 1 describes a pergola that has four posts, short beams spanning between the posts, long beams perpendicular to the beams, and a roof member composed of louvers that are slightly longer than the short beams and installed in parallel at regular intervals.

[0003] For example, Patent Document 2 describes a pergola that is made up of posts, a frame fixed to the top of the posts, and many louvers installed inside the frame, and the frame is assembled as a unit by fixing each end of the frame to each other. The ends of the louvers are placed on and fixed to support walls that are formed horizontally from the side walls of the frame toward the inside of the frame.

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 3-71027 [Patent Document 2] JP 2001-329704 A Summary of the Invention [Problem to be solved by the invention]

[0005] The louvers in the above-mentioned conventional pergolas are made by arranging vertically oriented boards horizontally at a specified interval to prevent the accumulation of fallen leaves and other debris. Therefore, there is a problem that they cannot sufficiently block sunlight during the summer solstice when the sun is high in the sky, and they hardly provide any shade.

[0006] Therefore, an object of the present invention is to provide a pergola that can prevent the accumulation of fallen leaves and other debris and can provide plenty of shade even on the summer solstice. [Means for solving the problem]

[0007] The pergola of the present invention is a pergola equipped with a frame body attached to the upper part of the posts, and a number of slats are installed at regular intervals in the horizontal direction, and each of the slats has a substantially vertical portion extending in a substantially vertical direction, an upwardly inclined portion extending diagonally upward from the upper end of the substantially vertical portion, and a downwardly inclined portion extending diagonally downward from the lower end of the substantially vertical portion on the opposite side to the upwardly inclined portion.

[0008] According to the pergola of the present invention, the plurality of slats each have a substantially vertical portion extending in a substantially vertical direction, an upward inclined portion extending diagonally upward from the upper end of the substantially vertical portion, and a downward inclined portion extending diagonally downward from the lower end of the substantially vertical portion on the opposite side to the upward inclined portion, so that it is possible to provide a large amount of shade even if the installation interval is increased, and by increasing the installation interval, it is possible to prevent the accumulation of debris such as fallen leaves. In particular, debris that slides down the upper surface of the upward inclined portion is accelerated by free falling once at the substantially vertical portion before reaching the downward inclined portion, and slides down the upper surface of the downward inclined portion with great force, thereby preventing the accumulation of debris.

[0009] The pergola of the present invention preferably has mounting parts at both ends of the multiple slats in the longitudinal direction for mounting the multiple slats to the frame in an adjustable angle. This makes it possible to adjust the shade by changing the angle according to the solar altitude and installation direction at the installation location of the pergola of the present invention. Effect of the Invention

[0010] (1) The pergola of the present invention makes it possible to prevent the accumulation of fallen leaves and other debris and to provide ample shade even on the summer solstice.

[0011] (2) By having mounting sections provided at both longitudinal ends of the multiple slats for attaching the multiple slats to the frame body in an angle adjustable manner, the angle can be changed depending on the solar altitude at the installation location of the pergola and the installation direction, etc., and the type of shade created can be adjusted.

[0013] FIG. 1 is a plan view of a pergola in an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, FIG. 3 is an enlarged cross-sectional view of the slat portion in FIG. 2, FIG. 4 is an enlarged oblique view of the end of the slat portion in FIG. 2, and FIG. 5 is an enlarged view of the holes for mounting the slat portion on the frame body.

[0014] As shown in Figures 1 and 2, a pergola 1 according to an embodiment of the present invention comprises four posts 2, a frame 3 provided on the upper part of the posts 2, and a plurality of slats 4 mounted at regular intervals in the horizontal direction on the frame 3. The posts 2 are formed, for example, from square timbers made of recycled wood. The frame 3 is formed from four aluminum alloy square timbers 30A respectively erected on the posts 2, strips 30B made of steel plate mounted between the four square timbers, and strips 30C made of recycled wood that cover the outside of strips 30B.

[0015] 3 and 4, the blade portion 4 has a substantially vertical portion 40 extending in a substantially vertical direction, an upward inclined portion 41 extending diagonally upward from an upper end portion 40A of the substantially vertical portion 40, and a downward inclined portion 42 extending diagonally downward from a lower end portion 40B of the substantially vertical portion 40 on the opposite side to the upper inclined portion 41. Furthermore, mounting portions 43 for mounting the blade portion 4 to the frame body 3 are provided on both ends of the blade portion 4 in the longitudinal direction.

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

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

[0018] The mounting portion 43 includes a mounting plate 45 having two mounting holes 45A and 45B for fixing to the frame 3 with a bolt and nut. A fixing metal fitting 46 having a shape similar to that of the fixing metal fitting 44 is welded to the mounting plate 45. The fixing metal fitting 46 is fixed to the ends of the substantially vertical portion 40, the upper inclined portion 41, and the lower inclined portion 42 with a bolt and nut. As shown in FIG. 3, the mounting hole 45A is formed in a position within a range of a V-shape formed between the upper inclined portion 41 and the substantially vertical portion 40. The mounting hole 45B is formed in a position within a range of a V-shape formed between the lower inclined portion 42 and the substantially vertical portion 40. The mounting holes 45A and 45B are located at point symmetric positions with respect to the center of the substantially vertical portion 40.

[0019] On the other hand, the frame body 3 to which the slat portion 4 is attached is provided with four mounting holes 31A, 31B, 32A, and 32B as shown in Fig. 5. The mounting plate 45 of the slat portion 4 is fixed with a bolt and nut by aligning the mounting hole 45A with the mounting hole 31A or the mounting hole 32A of the frame body 3. Also, the mounting hole 45B of the mounting plate 45 is aligned with the mounting hole 31B or the mounting hole 32B of the frame body 3 and fixed with a bolt and nut.

[0020] The mounting holes 31A, 31B of the frame 3 are provided at positions where the approximately vertical portion 40 is in the vertical direction when the slat portion 4 is fixed to the mounting holes 31A, 31B using the mounting holes 45A, 45B of the mounting plate 45 as shown in Fig. 3. The mounting hole 32B is provided at a position where the approximately vertical portion 40 is inclined at 10° from the vertical direction when the slat portion 4 is fixed to the mounting holes 31A, 32B using the mounting holes 45A, 45B of the mounting plate 45 as shown in Fig. 6. The mounting hole 32A is provided at a position where the approximately vertical portion 40 is inclined at 20° from the vertical direction when the slat portion 4 is fixed to the mounting holes 32A, 32B using the mounting holes 45A, 45B of the mounting plate 45 as shown in Fig. 7.

[0021] That is, the slat portion 4 can be attached to the frame body 3 in an angle adjustable manner by selectively fixing the slat portion 4 using the mounting holes 45A, 45B of the mounting plate 45 and the mounting holes 31A, 31B, 32A, 32B of the frame body 3. In this embodiment, the spacing between the multiple slat portions 4 is 312 mm, but as shown in Fig. 2, when the approximately vertical portion 40 is in the vertical direction, light rays do not escape from the solar altitude of 79.79° at the summer solstice.

[0022] In this way, the pergola 1 in this embodiment can provide a lot of shade even if the installation interval is increased, and by increasing the installation interval, it is possible to prevent the accumulation of fallen leaves and other debris, and provide a lot of shade even on the summer solstice. In particular, debris that slides down the top surface of the upward inclined portion 41 is accelerated by free falling once at the approximately vertical portion 40 before reaching the downward inclined portion 42, and slides down the top surface of the downward inclined portion 42 with great force, preventing the accumulation of debris.

[0023] In addition, in this embodiment, the pergola 1 has mounting portions 43 at both longitudinal ends of the multiple slat sections 4 for attaching the multiple slat sections 4 in an angle-adjustable manner, so that the angle can be changed depending on the solar altitude and installation direction at the installation location of the pergola 1, thereby adjusting the type of shade created.

[0024] Figure 8 is a diagram comparing the shade created by the pergola 1 of this embodiment and the conventional pergola 100. The conventional pergola 100 is equipped with louvers that are made of vertically oriented boards arranged horizontally at regular intervals. Figure 8 shows the pergola 1,100 as seen from due south.

[0025] As shown in Fig. 8, the pergola 1 of this embodiment can provide sufficient shade between 9:00 and 15:00 even on the summer solstice when the sun's altitude is high, but the conventional pergola 100 has many gaps in the louver boards in the shade throughout the day. There is almost no difference on the winter solstice when the sun's altitude is low. In other words, the pergola 1 of this embodiment can maintain shade throughout the year and prevent the accumulation of fallen leaves and other debris.

[0026] In this embodiment, the angle of the approximately vertical portion 40 can be adjusted to a selected angle of 0°, 10°, or 20° from the vertical direction, but it is also possible to make the angle adjustable in the range of 0 to 20° by making the mounting holes 45A, 45B of the mounting plate 45 and the mounting holes 31A, 31B, 32A, and 32B of the frame body 3, for example, elongated holes.

[0027] Furthermore, various materials may be used for constructing the pergola 1, such as aluminum alloy, steel, stainless steel, plastic, and wood. [Industrial Applicability]

[0028] The present invention is useful as a pergola that is installed in parks, gardens, etc. to provide protection from sunlight, and is particularly suitable as a pergola that prevents the accumulation of fallen leaves and other debris and can provide plenty of shade even on the summer solstice.
