Description

[Technical Field]

[0001] The present invention relates to a planter that can be installed on the wall surface of a stone retaining wall, for example. [Background technology]

[0002] The slopes of embankments or cuts formed in civil engineering works such as residential land development and road construction are protected by retaining walls constructed with stone masonry, block masonry, poured concrete, etc. In recent years, techniques have been proposed for installing planters (potted plants) in drainage holes embedded in retaining walls, with the aim of beautifying the retaining walls and increasing the added value of the entire retaining wall. For example, Patent Document 1 discloses a decorative cover for a retaining wall drainage hole, which includes an insertion part that is inserted into the drainage hole of the retaining wall, a cover part that is integrated with the insertion part, and a planter that is fixed to the outside of the cover part. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 2920009 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the decorative cover described in Patent Document 1 has the problem that wastewater from the drain outlet is discharged through an opening provided below the cover, and therefore the wastewater stains the surface of the retaining wall, detracting from the beauty of the retaining wall provided by the decorative cover. Furthermore, since it is necessary to form claw holes in the drain outlet to fit the fixing claws provided in the insertion part of the decorative cover, it is time-consuming and costly to process the drain outlet when installing the decorative cover. Moreover, since it is not easy to form claw holes after the construction of the retaining wall, there is a problem that it is necessary to form the claw holes in the drain outlet in advance during the construction stage of the retaining wall.

[0005] In view of the above circumstances, the object of the present invention is to provide a planter that can prevent damage to retaining walls caused by drainage and can be easily installed on existing retaining walls that do not have claw holes. [Means for solving the problem]

[0006] In order to achieve the above object, one aspect of the present invention provides a planter that is installed on a retaining wall having a drainage outlet, and includes a planter body and an attachment portion. The planter body has a space capable of accommodating additional soil. The mounting portion is provided on the planter body, has a through hole that connects the space to the drain outlet, and fits around or inside the drain outlet.

[0007] In the planter, drainage from the drain outlet is guided into the space in the planter body through the through-holes in the attachment part attached to the drain outlet, thereby preventing the retaining wall from being soiled by the drainage. Also, since the attachment part is configured to attach the planter body to the drain outlet by fitting around or inside the drain outlet, the planter can be installed on the drain outlet without any special processing being done on the drain outlet.

[0008] The mounting portion may further include a cylindrical portion having a first end connected to the through hole and a second end that fits inside the drain outlet, thereby enabling the planter to be stably held on the retaining wall.

[0009] The second end portion may have a plurality of divided regions arranged circumferentially around the cylindrical portion, and the mounting portion may further have a screw mechanism provided inside the cylindrical portion for expanding the diameter of the second end portion, thereby increasing the holding force of the planter against the retaining wall.

[0010] Alternatively, the second end portion may have a plurality of divided regions arranged circumferentially around the tubular portion, and the plurality of divided regions may include at least one pair of divided pieces facing each other in a radial direction of the tubular portion that intersects with the height direction of the planter body. This converts stress acting on the tubular portion in the height direction into stress that spreads each divided piece laterally, thereby improving the adhesion between the drain outlet and the tubular portion.

[0011] The planter body may include a bottom having a drain hole communicating with the space.

[0012] In this case, the planter body may further include a water pipe that is erected in the space and guides liquid in the space above a predetermined water level to the drain hole. This keeps the liquid level in the planter below the predetermined water level Lw, preventing excessive water from accumulating in the planter 10 when a large amount of water is being discharged from the drain outlet or during rainy weather. [Effects of the Invention]

[0013] According to the present invention, it is possible to prevent the retaining wall from being soiled by drainage water, and it is also possible to easily install planters on the retaining wall. [Brief explanation of the drawings]

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0016] First Embodiment Figure 1 is an overall view of a planter 100 according to a first embodiment of the present invention, where (A) is a front view, (B) is a plan view, and (C) is a schematic side cross-sectional view showing the state when installed on a retaining wall W. In the figure, the X-axis, Y-axis, and Z-axis indicate three mutually orthogonal axial directions, with the X-axis corresponding to the depth direction, the Y-axis corresponding to the width direction, and the Z-axis corresponding to the height direction.

[0017] The planter 100 of this embodiment is configured as a retaining wall planter to be installed on a retaining wall W. The planter 100 has a planter body 10 having a space S for accommodating added soil C, and an attachment part 11 that is attached to the tip (drain outlet Wh) of a drainage pipe (or drainage pipe) Wp buried in the retaining wall W. The added soil C may be accommodated directly in the space S, or indirectly in the space S via a container (not shown) such as a pot or flowerpot that can accommodate the added soil C.

[0018] The planter body 10 has a front surface 10f, a back surface 10b, and two side surfaces 10s. The top surface 10a of the planter body 10 is open, and the front surface 10f and back surface 10b are connected to the bottom surface 10v so as to form a roughly V-shape when viewed from the Y-axis direction. Hanging portions 13 are provided at the ends of the top surface 10a of the front surface 10f and both side surfaces 10s to serve as drainers.

[0019] The angle θ (see FIG. 1(C)) between the front surface 10f and the back surface 10b is not particularly limited and is, for example, 30° or less. In particular, by forming the angle of the back surface 10b to match the slope of the retaining wall W, the planter 100 can be installed on the retaining wall W with the top surface 10a maintained horizontal. Furthermore, by forming the bottom surface 10v into a substantially V-shape, it is possible to prevent the front surface 10f from crossing the slope of the retaining wall W (the bottom line of the slope). The slope of the retaining wall W relative to the horizontal direction is, for example, 70 to 80 degrees.

[0020] The shape of the planter body 10 is not limited to the above example. For example, the bottom portion 10v may be flat, and the front portion 10f may be curved and convex outward.

[0021] The size of the planter body 10 is not particularly limited, and for example, the depth along the X-axis direction is 150 to 250 mm, the width along the Y-axis direction is 300 to 400 mm, and the height along the Z-axis direction is 150 to 250 mm. The material of the planter body 10 is also not particularly limited, and is typically a synthetic resin material such as polypropylene or polyvinyl chloride, but other materials such as metal or ceramic may also be used. The thickness of each part of the planter body 10 is also not particularly limited, and if the planter body 10 is made of a synthetic resin material, the thickness is, for example, 3 mm.

[0022] The mounting portion 11 is provided on the rear surface 10b of the planter body 10 to mount the planter body 10 to the drain outlet Wh of the retaining wall W. In this embodiment, the mounting portion 11 is formed as a circular through-hole 11h that fits around the drain outlet Wh. The through-hole 11h is formed in the center of the rear surface 10b in the width direction (Y-axis direction), and has an inner diameter larger than the outer diameter (approximately 80 mm) of the drain pipe Wp.

[0023] In this embodiment, the drain pipe Wp is embedded inside the retaining wall W so that its tip protrudes a predetermined amount from the surface of the retaining wall W. The planter 100 is installed on the retaining wall W by passing the tip of the drain pipe Wp through the through hole 11h and hanging from the tip of the drain pipe Wp (see FIG. 1(C)). At this time, the back surface portion 10b functions as a contact portion that contacts the surface of the retaining wall W, and holds the planter 100 in a predetermined position on the retaining wall W.

[0024] The through hole 11h further functions to connect the space S of the planter body 10 to the drain outlet Wh. As a result, the moisture in the back soil of the retaining wall W that is discharged through the drain outlet Wh is guided into the space S and received by the additional soil C contained in the space S.

[0025] Furthermore, drain holes 12 are provided in the bottom 10v of the planter body 10. This allows excess water in the soil C to be discharged from the bottom 10v. The drain holes 12 are provided at multiple locations (three locations in this example) at predetermined intervals in the width direction (Y-axis direction) of the planter body 10. The number and arrangement of the drain holes 12 are not particularly limited.

[0026] As described above, in the planter 100 of this embodiment, the mounting portion 11 for mounting the planter body 10 to the drain outlet Wh of the retaining wall W has a through-hole that connects the drain outlet to the inside of the planter body 10. This allows the drainage water from the drain outlet Wh to be received by the added soil C in the space S of the planter 100, preventing the surface of the retaining wall W from being soiled by the drainage water. In addition, the drainage water from the drain outlet Wh can be used to water the added soil C, eliminating the need for watering or reducing the frequency of watering.

[0027] Furthermore, according to this embodiment, the planter 100 can be easily installed in the retaining wall W simply by inserting the tip of the drain pipe Wp (the drain outlet Wh) into the through hole 11a. Therefore, the planter 100 can be installed in the drain outlet Wh without any special processing being performed on the drain outlet Wh. This allows the planter 100 to be easily installed in a drain outlet Wh that is embedded in an existing retaining wall W.

[0028] Furthermore, the planter 100 is held stably on the surface of the retaining wall W by utilizing its own weight including the added soil C. Moreover, the planter 100 can be fitted tightly to the retaining wall W without creating a large gap between it and the retaining wall W, enhancing the sense of unity between the planter 100 and the retaining wall W. This improves the aesthetic appearance of the retaining wall W.

[0029] <Second embodiment> 2 is a side cross-sectional view showing a planter 200 according to a second embodiment of the present invention installed on a retaining wall W. The following mainly describes the configurations that differ from the first embodiment, and the same components as those in the first embodiment are given the same reference numerals and their description will be omitted or simplified.

[0030] The planter 200 of this embodiment has a planter body 10 and an attachment part 21, the configuration of which differs from that of the first embodiment. In this embodiment, the attachment part 21 has a through hole 11a, a fixing piece 15 provided on the upper edge of the through hole 11a, an insertion pipe 16 as a tubular part inserted into the drain outlet Wh and the through hole 11a, and a fastener 17 that fixes the fixing piece 15 and the insertion pipe 16 together.

[0031] The fixing piece 15 is a flat or partially curved plate extending horizontally from the upper edge of the through hole 11a toward the space S. The insertion pipe 16 functions as a relay member connecting the drain outlet Wh to the planter body 10, and also as a communication passageway connecting the drain outlet Wh to the space S of the planter body 10. The fixing device 17 is typically a fastener such as a screw, bolt, or nut.

[0032] The insertion pipe 16 has a first end 16a that connects to the through hole 11a and a second end 16b that fits inside the drain outlet Wh. Typically, the planter 200 is installed on the retaining wall W by fixing the first end 16a to the through hole 11a (fixing piece 15) and then inserting the second end 16b into the drain outlet Wh. However, this is not limited to this, and the planter 200 may also be installed on the retaining wall W by inserting the second end 16b into the drain outlet Wh and then fixing the first end 16a to the through hole 11a.

[0033] The insertion pipe 16 is a cylindrical pipe made of synthetic resin or metal and has an outer diameter (e.g., 75 mm or less) smaller than the inner diameter of the drain outlet Wh. The length of the insertion pipe 16 is not particularly limited as long as it is long enough to stably hold the planter 200 on the retaining wall W, and is, for example, 150 mm to 200 mm. Note that the insertion pipe 16 is not limited to being formed as a separate member from the planter body 10, and may be formed integrally with the planter body 10. In this case, a cylindrical portion is formed on the back surface portion 10b of the planter body 10 concentric with the through-hole 11a.

[0034] The planter 200 of this embodiment further has legs 14. The legs 14 are provided on the bottom 10v of the planter body 10 so as to protrude from the back surface 10b toward the retaining wall W. The legs 14 function as contact parts that come into contact with the surface of the retaining wall W, and hold the planter 200 in a predetermined position on the retaining wall W. The number of legs 14 is not particularly limited, and may be one or more. The shape of the legs 14 is also not particularly limited, and any appropriate shape such as a rod shape or a rib shape can be used.

[0035] The legs 14 may be omitted if necessary. For example, the distance between the surface of the retaining wall W and the back surface 10b of the planter body 200 can be set arbitrarily by changing the fixed position of the insertion pipe 16 relative to the planter body 10. In this case, the planter 200 may be installed so that the back surface 10b contacts the surface of the retaining wall W, as in the first embodiment.

[0036] This embodiment also provides the same advantageous effects as the first embodiment. In particular, this embodiment includes an insertion pipe 16 that is inserted into the drain outlet Wh, allowing the planter 200 to be stably held in the drain outlet Wh. This prevents the planter 200 from accidentally falling off the retaining wall W. Furthermore, the planter 200 can be installed in a drain outlet where the tip of the drain pipe Wp does not protrude from the surface of the retaining wall W.

[0037] <Third embodiment> 3 is a side cross-sectional view showing a planter 300 according to a third embodiment of the present invention installed on a retaining wall W. The following mainly describes the configurations that differ from the first and second embodiments, and the same components as those in the first and second embodiments are designated by the same reference numerals, and their description will be omitted or simplified.

[0038] The planter 300 of this embodiment has a planter body 10 and an attachment part 31, and the configuration of the attachment part 31 differs from that of the first and second embodiments. In this embodiment, the attachment part 31 has a through hole 11a, a tubular part 18 formed concentrically with the through hole 11a, and a screw mechanism part 30 installed inside the tubular part 18. In this embodiment, the tubular part 18 is inserted into the drain outlet Wh and has its diameter expanded by the screw mechanism part 30, so that the outer surface of the tubular part 18 can be brought into tight contact with the inner surface of the drain outlet Wh (drain pipe Wp).

[0039] 4 is a side view of the planter 300. The tubular portion 18 has a cylindrical shape with a first end 18a connected to the through-hole 11a and a second end 18b that fits into the drain outlet Wh. The tubular portion 18 is formed integrally with the planter body 10 and is typically molded from the same resin material as the planter body 10. The tubular portion 18 functions as a relay member that connects the drain outlet Wh to the planter body 10 and as a communication passage that connects the drain outlet Wh to the space S of the planter body 10.

[0040] The second end 18b of the cylindrical portion 18 has a plurality of divided regions arranged in the circumferential direction of the cylindrical portion 18. In this embodiment, the cylindrical portion 18 is divided into two regions (upper region 181 and lower region 182) in the vertical direction (Z-axis direction in the figure) by a slit portion 180 formed along the axial direction of the cylindrical portion 18 (X-axis direction in the figure). The length of the slit portion 180 is not particularly limited, and may be any length that allows the second end 18b to elastically deform toward the inner circumferential surface of the drain pipe Wp.

[0041] As shown in FIG. 3 , the screw mechanism 30 has first and second shaft portions 301, 302 that face each other in the vertical direction (Z-axis direction), and a buckle 303 that threads onto the first and second shaft portions 301, 302. The first shaft portion 301 is a threaded member that is fixed to the inner circumferential surface of the upper region 181 of the tubular portion 18 and whose lower end threads into the buckle 303. The second shaft portion 302 is a threaded member that is fixed to the inner circumferential surface of the lower region 182 of the tubular portion 18 and whose upper end threads into the buckle 303 and whose lower end is fixed to the inner circumferential surface of the lower region 182 of the tubular portion 18. The thread groove of the first shaft portion 301 is formed in the opposite direction to the thread groove of the second shaft portion 302. Therefore, by rotating the buckle 303 in one direction, the first shaft portion 301 and the second shaft portion 302 move in directions away from each other, thereby expanding the diameter of the second end portion 18b of the tubular portion 18. On the other hand, by rotating buckle 303 in the other direction, first shaft portion 301 and second shaft portion 302 move in directions in which they approach each other, thereby reducing the diameter of second end portion 18b of the cylindrical portion.

[0042] The planter 300 of this embodiment, configured as described above, can achieve the same effects as the first embodiment. In this embodiment, after the tubular portion 18 is inserted into the drain outlet Wh and engaged, the first shaft portion 301 and the second shaft portion 302 are moved away from each other by rotating the buckle 303, thereby closely contacting the upper region 181 and the lower region 182 of the tubular portion 18 with the inner circumferential surface of the drain pipe Wp. This improves the holding strength of the planter 300 relative to the drain outlet Wh, allowing the planter 300 to be more stably installed relative to the retaining wall W. The planter 300 can also be installed relative to a drain outlet where the tip of the drain pipe Wp does not protrude from the surface of the retaining wall W.

[0043] The buckle 303 may be rotated by an operator's fingers through the through hole 11a, or by using an appropriate tool. In this case, by forming the outer circumferential surface of the buckle 303 into a polygonal shape, the buckle 303 can be easily operated with a wrench or the like. In addition, to improve adhesion between the tubular portion 18 and the drain pipe Wp, as shown in FIG. 5, the outer circumferential surface of the tubular portion 18 may be coated with a coating layer 310 made of an elastic material such as rubber.

[0044] Furthermore, the second end 18b of the tubular portion 18 is not limited to being expandable in the vertical direction, but may be expandable in the horizontal or diagonal direction. The number of divisions of the second end 18b is not limited to two, but may be three or more, as long as at least two of these regions are deformable toward the inner circumferential surface of the drainage pipe Wp.

[0045] The cylindrical portion 18 is not limited to being integrally formed with the planter body 10, but may be formed as a separate member from the planter body 10, as in the second embodiment (FIG. 2) described above.

[0046] <Fourth embodiment> 6 is a side cross-sectional view showing a planter 400 according to a fourth embodiment of the present invention installed on a retaining wall W. The following mainly describes configurations that differ from the first to third embodiments, and configurations that are similar to those in the first embodiment are given the same reference numerals and their description will be omitted or simplified.

[0047] The planter 400 of this embodiment has a planter body 10 and an attachment part 41, and the configuration of the attachment part 41 differs from that of the first to third embodiments. In this embodiment, the attachment part 41 has a through hole 11a and a tubular part 19 formed concentrically with the through hole 11a. In this embodiment, the tubular part 19 inserted into the drain outlet Wh is expanded in diameter by the weight of the planter 400 (including the added soil), so that the outer surface of the tubular part 19 can be brought into tight contact with the inner surface of the drain outlet Wh (drain pipe Wp).

[0048] FIG. 7 is a schematic perspective view of the rear portion 10b side of the planter 400, showing the configuration of the tubular portion 19. The tubular portion 19 has a partially cylindrical shape with a first end 19a connected to the through-hole 11a and a second end 19b that fits into the drain outlet Wh. The tubular portion 19 is formed so that its outer diameter gradually increases from the first end 19a to the second end 19b, and the opening diameter of the second end 19b is slightly larger than the opening diameter of the drain outlet Wh. The tubular portion 19 is formed integrally with the planter body 10 and is typically molded integrally from the same resin material as the planter body 10. The tubular portion 19 functions as a relay member that connects the drain outlet Wh to the planter body 10 and as a communication passage that connects the drain outlet Wh to the space S of the planter body 10.

[0049] The second end 19b of the cylindrical portion 19 has a plurality of divided regions arranged in the circumferential direction of the cylindrical portion 19. In this embodiment, a pair of divided pieces 191, 192 facing each other in the radial direction are formed by a slit 190 formed along the axial direction of the cylindrical portion 19. The pair of divided pieces 191, 192 face each other in the radial direction of the cylindrical portion 19, a direction that intersects with the height direction of the planter body 10. The shape of the slit 190 is not particularly limited, and in this embodiment, the slit is formed so that the slit width increases from the first end 19a side to the second end 19b side. This makes it easier for each divided piece 191, 192 to deform not only in the radial direction of the cylindrical portion 19 but also in the circumferential direction.

[0050] FIG. 8 is a cross-sectional view of the main part as seen from the front (X-axis direction) showing the relationship between the drain outlet Wh (drain pipe Wp) and the divided pieces 191, 192 of the tubular part 19 inserted therein.

[0051] The cylindrical portion 19 is inserted into the drain outlet Wh with each of the segments 191, 192 elastically deformed radially inward (with the second end 19b of the cylindrical portion 19 contracted). This causes the outer circumferential surface of the cylindrical portion 19 to adhere tightly to the inner circumferential surface of the drain outlet Wh due to the radially outward restoring force of each of the segments 191, 192. Furthermore, as shown in FIG. 8 , stress (bending stress) F1 is applied to the cylindrical portion 19 in the height direction (Z-axis direction) inside the drain outlet Wh due to the weight of the planter 400 (including the soil). Because each of the segments 191, 192 of the cylindrical portion 19 is formed in a direction inclined relative to the height direction, part of the stress F1 acting in the height direction is converted into stress F2, which expands the diameter of each of the segments 191, 192 in the lateral direction (Y-axis direction).

[0052] As a result, the adhesion between the divided pieces 191, 192 and the inner wall of the drain pipe Wp is increased, and at the same time, the lateral (Y-axis) tension force (F2) enhances the effect of preventing the tubular portion 19 from slipping out of the drain pipe Wp. This allows the planter 400 to be stably held on the retaining wall W without the need for a separate auxiliary mechanism. Note that, to increase the adhesion between the tubular portion 19 and the drain pipe Wp, the outer circumferential surface of the tubular portion 19 may be coated with a covering layer 310 made of an elastic material such as rubber, as shown in FIG. 5.

[0053] The angular positions of the segments 191, 192 of the tubular portion 19 are set so that they face each other in a direction inclined by an angle α with respect to a vertical line parallel to the Z-axis direction. The magnitude of the angle α is not particularly limited and is, for example, between 15° and 75°, more preferably between 30° and 60°, and is 45° in this embodiment.

[0054] The number of segments 191, 192 is not limited to two. For example, as shown in Fig. 9, the tubular portion 19 may have two segments 193, 194 in addition to the segments 191, 192. In this case, the segments 193, 194 are arranged at 90° intervals between the segments 191, 192. Even in this case, the stress F1 applied in the vertical direction to each of the segments 191 to 194 can be converted into a lateral tension force (F2), thereby improving adhesion to the drainage pipe Wp.

[0055] Furthermore, as shown in Figure 10, the rear surface 10b of the planter body 10 may be provided with an annular recess 11b around the through hole 11a to accommodate the tip of the drain pipe Wp. This allows the planter 400 to be placed closer to the surface of the retaining wall W, enhancing the sense of unity of the planter 400 with the retaining wall W. This configuration is also applicable to the second and third embodiments described above.

[0056] <Fifth embodiment> 11 is a side cross-sectional view showing a planter 500 according to a fifth embodiment of the present invention installed on a retaining wall W. The following mainly describes configurations that differ from the first to fourth embodiments, and configurations that are similar to those in the first embodiment are given the same reference numerals and their description will be omitted or simplified.

[0057] The planter 500 of this embodiment differs from the first to fourth embodiments in that it further includes water pipes 51 erected in the space S of the planter body 10. The water pipes 51 are made of straight pipe members arranged at multiple locations in the space S, and are configured to be able to guide liquid in the space S that is equal to or higher than a predetermined water level Lw to a drain hole 12 provided in the bottom 10v of the planter body 10.

[0058] The mounting portion 41 is configured in the same manner as in the fourth embodiment, and therefore a description thereof will be omitted here. Note that the mounting portion 41 may be replaced by the mounting portions 11 to 31 described in the first to third embodiments.

[0059] In this embodiment, the water pipes 51 are attached to a partition plate 52 provided near the bottom 10v of the planter body 10. The partition plate 52 is a plate that divides the interior of the planter body 10 into a space S for accommodating the added soil and a drain space S1 below it, and has multiple through-holes on its surface that direct excess water in the added soil to the bottom 10v of the planter body 10 and the drain hole 12. The upper end of each water pipe 51 is located at a height equal to or higher than the predetermined water level Lw, and the lower end is fixed to the partition plate 52.

[0060] The predetermined water level Lw is not particularly limited, and is typically set at the surface of the added soil or a position slightly higher than that. The fixing positions of the water pipes 51 are not particularly limited, and they are placed at a predetermined interval in the front-to-back or width direction of the planter body 10. The number of water pipes 51 is not particularly limited, and there may be only one.

[0061] In the planter 500 of this embodiment, which is configured as described above, the planter body 10 is provided with the water pipe 51 configured as described above inside, so that wastewater or rainwater that has accumulated in the space S and is above a predetermined water level Lw can be directly discharged to the drain hole 12 via the water pipe 51. This keeps the liquid level inside the planter 10 below the predetermined water level Lw, preventing more water than necessary from accumulating inside the planter 10 when a large amount of water is being discharged from the drain pipe Wp or during rainy weather. As a result, the planter 500 is prevented from falling off the retaining wall W due to its increased weight, and the plants inside the planter 500 are protected from excess water.

[0062] Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the above-described embodiments and that various modifications can be made.
