Description

The present invention relates to a planter that can be installed on the wall surface of a masonry retaining wall, for example.

The slopes of embankments or cuts formed in civil engineering works such as housing development and road construction are protected by retaining walls constructed with stone masonry, block masonry, poured concrete, etc. In recent years, technology has been proposed for installing planters (plant pots) 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.

Patent No. 2920009

However , if more water than necessary accumulates in the planter when there is a large amount of discharge from the drain pipe or during rainy weather, there are problems in that the planter may fall off the retaining wall due to its increased weight and the plants in the planter may not be protected from excess water.

In view of the above circumstances, an object of the present invention is to provide a planter that can prevent more water than necessary from accumulating when there is a large amount of drainage or during rainy weather .

In order to achieve the above object, a planter according to one embodiment of the present invention is a planter to be installed on a retaining wall having a drainage outlet, and comprises 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.

In the above planter, the drainage from the drain is guided to the space in the planter body through holes in the attachment part that is attached to the drain, so that the damage to the retaining wall caused by the drainage can be suppressed. In addition, the attachment part is configured to attach the planter body to the drain by fitting around the drain or inside the drain, so the planter can be installed in the drain without making any special modifications to the drain.

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 drainage outlet. This allows the planter to be stably held on the retaining wall.

The second end portion may have a plurality of divided regions arranged in the circumferential direction of 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. This increases the holding force of the planter against the retaining wall.

Alternatively, the second end portion may have a plurality of divided regions arranged in the circumferential direction of the tubular portion, and the plurality of divided regions may include at least a pair of divided pieces that face each other in a radial direction of the tubular portion and in a direction that intersects with the height direction of the planter body. This converts stress applied to the tubular portion in the height direction into stress that spreads each divided piece laterally, thereby improving the adhesion between the drainage outlet and the tubular portion.

The planter body may include a bottom having a drain hole that communicates with the space.

In this case, the planter body may further have a water pipe that is erected in the space and directs liquid in the space that is at or above a predetermined water level to the drain hole. This keeps the liquid level in the planter below the predetermined water level Lw, so that more water than necessary does not accumulate in the planter 10 when a large amount of water is discharged from the drain or during rainy weather.

This invention can prevent the retaining wall from being soiled by drainage and also makes it easy to install planters on the retaining wall.

The following describes an embodiment of the present invention with reference to the drawings.

First Embodiment
FIG. 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 installed on a retaining wall W.
In the figure, the X-axis, Y-axis, and Z-axis indicate three mutually perpendicular 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.

The planter 100 of this embodiment is configured as a retaining wall planter that is 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 water drainage pipe) Wp buried in the retaining wall W. The added soil C may be directly accommodated in the space S, or may be indirectly accommodated in the space S via a container (not shown) such as a pot or a flowerpot that can accommodate the added soil C.

The planter body 10 has a front portion 10f, a back portion 10b, and two side portions 10s. The top surface 10a of the planter body 10 is open, and the front portion 10f and the back portion 10b are connected to the bottom portion 10v so as to form a substantially V-shape when viewed from the Y-axis direction. The front portion 10f and both side portions 10s have hanging portions 13 at the ends of the top surface 10a side of the front portion 10f and both side portions 10s, which serve as drains.

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

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

The size of the planter body 10 is not particularly limited, and for example, the depth dimension along the X-axis direction is 150 to 250 mm, the width dimension along the Y-axis direction is 300 to 400 mm, and the height dimension 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 may be other materials such as metal or ceramic. The thickness of each part of the planter body 10 is also not particularly limited, and when the planter body 10 is made of a synthetic resin material, the thickness is, for example, 3 mm.

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

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.

The through hole 11h further functions to connect the space S of the planter body 10 to the drainage outlet Wh. This allows the moisture in the back soil of the retaining wall W that is discharged through the drainage outlet Wh to be guided to the space S and received by the additional soil C contained in the space S.

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. Note that there is no particular limit to the number or arrangement of the drain holes 12.

As described above, in the planter 100 of this embodiment, the mounting portion 11 for mounting the planter body 10 to the drainage outlet Wh of the retaining wall W has a through hole that connects the drainage outlet to the inside of the planter body 10. This allows the drainage water from the drainage 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 drainage outlet Wh can be used to water the added soil C, eliminating the need for watering or reducing the frequency of watering.

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

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 against the retaining wall W without creating a large gap between the planter 100 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.

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. Below, configurations different from the first embodiment will be mainly described, and configurations similar to those in the first embodiment will be given the same reference numerals and descriptions thereof will be omitted or simplified.

The planter 200 of this embodiment has a planter body 10 and an attachment part 21, and the configuration of the attachment part 21 differs from that of the first embodiment described above. 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 cylindrical part that is inserted into each of the drain hole Wh and the through hole 11a, and a fixing device 17 that fixes the fixing piece 15 and the insertion pipe 16 together.

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 plug pipe 16 functions as a relay member that connects the drain outlet Wh to the planter body 10, and as a passageway that connects 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, nut, etc.

The insertion pipe 16 has a first end 16a that is connected 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 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.

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 drainage hole Wh. The length of the insertion pipe 16 is not particularly limited as long as it is a length that can 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 an example in which it is made of a separate member from the planter body 10, but may be formed integrally with the planter body 10. In this case, a cylindrical tubular portion is formed in the back portion 10b of the planter body 10 concentric with the through hole 11a.

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 towards 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 either single or multiple. 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 adopted.

The legs 14 may be omitted if necessary. For example, it is possible to arbitrarily set the distance between the surface of the retaining wall W and the back portion 10b of the planter body 200 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 portion 10b contacts the surface of the retaining wall W, as in the first embodiment.

In this embodiment, the same effects as those of the first embodiment can be obtained. In particular, according to this embodiment, since the plug pipe 16 is provided to be inserted into the drain outlet Wh, the planter 200 can be stably held at the drain outlet Wh. This makes it possible to prevent the planter 200 from accidentally falling off the retaining wall W. In addition, the planter 200 can be installed even at a drain outlet where the tip of the drain pipe Wp does not protrude from the surface of the retaining wall W.

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. Below, configurations different from the first and second embodiments will be mainly described, and configurations similar to those in the first and second embodiments will be given the same reference numerals and descriptions thereof will be omitted or simplified.

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

Figure 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 drainage outlet Wh. The tubular portion 18 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 18 functions as a relay member that connects the drainage outlet Wh to the planter body 10, and as a communication passage that connects the drainage outlet Wh to the space S of the planter body 10.

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, 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.

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

The planter 300 of this embodiment configured as described above can achieve the same effect as the first embodiment described above. In this embodiment, after the tubular portion 18 is inserted into the drainage 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, so that the upper region 181 and the lower region 182 of the tubular portion 18 are tightly attached to the inner circumferential surface of the drainage pipe Wp. This improves the holding strength of the planter 300 against the drainage outlet Wh, and the planter 300 can be more stably installed against the retaining wall W. The planter 300 can also be installed against a drainage outlet where the tip of the drainage pipe Wp does not protrude from the surface of the retaining wall W.

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

Furthermore, the second end 18b of the tubular portion 18 is not limited to being configured to be expandable in the vertical direction, but may be configured to be expandable in the horizontal or diagonal direction. Also, 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 capable of deforming toward the inner circumferential surface of the drain pipe Wp.

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

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. Below, configurations different from the first to third embodiments will be mainly described, and configurations similar to those in the first embodiment will be given the same reference numerals and descriptions thereof will be omitted or simplified.

The planter 400 of this embodiment has a planter body 10 and an attachment portion 41, and the configuration of the attachment portion 41 differs from that of the first to third embodiments described above. In this embodiment, the attachment portion 41 has a through hole 11a and a tubular portion 19 formed concentrically with the through hole 11a. In this embodiment, the tubular portion 19 inserted into the drainage outlet Wh is expanded in diameter by the weight of the planter 400 (including the topsoil), so that the outer peripheral surface of the tubular portion 19 can be brought into close contact with the inner peripheral surface of the drainage outlet Wh (drainage pipe Wp).

Figure 7 is a schematic perspective view of the rear portion 10b side showing the configuration of the tubular portion 19 of the planter 400. 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 drainage hole Wh. The tubular portion 19 is formed so that the outer diameter gradually increases from the first end 19a to the second end 19b, and the opening diameter of the second end 19b is formed slightly larger than the opening diameter of the drainage hole Wh. The tubular portion 19 is formed integrally with the planter body 10, and is typically molded integrally with the planter body 10 using the same resin material. The tubular portion 19 functions as a relay member that connects the drainage hole Wh to the planter body 10, and as a communication passage that connects the drainage hole Wh to the space portion S of the planter body 10.

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 that face each other in the radial direction are formed by a slit portion 190 formed along the axial direction of the cylindrical portion 19. These pair of divided pieces 191, 192 face each other in the radial direction of the cylindrical portion 19, which is a direction that intersects with the height direction of the planter body 10. The shape of the slit portion 190 is not particularly limited, and in this embodiment, the slit width is formed so that it becomes wider 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.

Figure 8 is a cross-sectional view of the main part 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.

The cylindrical portion 19 is inserted into the drain Wh with each of the segments 191, 192 elastically deformed radially inward (with the second end 19b of the cylindrical portion 19 contracted). As a result, the outer circumferential surface of the cylindrical portion 19 is brought into close contact with the inner circumferential surface of the drain Wh by the restoring force of each of the segments 191, 192 radially outward. Furthermore, as shown in FIG. 8, the cylindrical portion 19 is subjected to a stress (bending stress) F1 in the height direction (Z-axis direction) inside the drain Wh due to the weight of the planter 400 (including the soil). Since each of the segments 191, 192 of the cylindrical portion 19 is formed in a direction inclined with respect to the height direction, part of the stress F1 acting in the height direction is converted into a stress F2 that expands the diameter of each of the segments 191, 192 in the horizontal direction (Y-axis direction).

As a result, the adhesion between the split 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 coming off 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. In addition, to increase the adhesion between the tubular portion 19 and the drain pipe Wp, as shown in FIG. 5, the outer circumferential surface of the tubular portion 19 may be coated with a coating layer 310 made of an elastic material such as rubber.

The angular positions of the segments 191, 192 of the tubular section 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, 15° to 75°, more preferably 30° to 60°, and is 45° in this embodiment.

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 vertically to each of the segments 191-194 can be converted into a lateral tension force (F2), improving adhesion to the drain pipe Wp.

Furthermore, as shown in FIG. 10, the rear portion 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 drainage pipe Wp. This allows the planter 400 to be brought 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 can be similarly applied to the second and third embodiments described above.

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. Below, configurations different from the first to fourth embodiments will be mainly described, and configurations similar to those in the first embodiment will be given the same reference numerals and descriptions thereof will be omitted or simplified.

The planter 500 of this embodiment differs from the first to fourth embodiments described above in that it further has 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 greater than a predetermined water level Lw to a drain hole 12 provided in the bottom 10v of the planter body 10.

The mounting portion 41 is configured in the same manner as in the fourth embodiment described above, so a description thereof will be omitted here. Note that mounting portions 11 to 31 described in the first to third embodiments may be used instead of mounting portion 41.

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 inside of the planter body 10 into a space S that contains the added soil and a drain space S1 below it, and has multiple through holes on its surface that guide 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 above-mentioned predetermined water level Lw, and the lower end is fixed to the partition plate 52.

The specified water level Lw is not particularly limited, and is typically set at the surface of the topsoil or a position slightly higher than that. The fixed positions of the water pipes 51 are not particularly limited, and they are placed at a specified 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 may be a single one.

In the planter 500 of this embodiment configured as described above, the planter body 10 is provided with the water passage pipe 51 configured as described above inside, so that drainage water or rainwater that is above a certain water level Lw and has accumulated in the space S can be directly discharged to the drain hole 12 via the water passage pipe 51. This keeps the liquid level in the planter 10 below the certain water level Lw, so that when there is a large amount of water being discharged from the drain pipe Wp or during rainy weather, more water than necessary does not accumulate in the planter 10. As a result, it is possible to prevent the planter 500 from falling off the retaining wall W due to an increase in its weight, and to protect the plants in the planter 500 from excess water.

The above describes an embodiment of the present invention, but the present invention is not limited to the above embodiment and can of course be modified in various ways.

For example, in the above embodiment, the drain outlet Wh is described as protruding horizontally from the surface of the retaining wall W, but the drain outlet Wh may protrude diagonally downward from the surface of the retaining wall W. In this case, the planters 200, 300, and 400 having a cylindrical portion (insertion pipe 16, cylindrical portions 18 and 19) as the attachment portion can be suitably applied.
