[0003] [Patent Document 1] Patent No. 5674702 Summary of the Invention [Problem to be solved by the invention]

[0004] The present inventors have recognized a problem in that the plant cultivation container described in Patent Document 1 has two side walls and two outer walls that may tilt outward due to the pressure of the soil.

[0005] An object of the present disclosure is to provide a plant cultivation device that can prevent a wall forming a soil storage chamber from tilting outward due to soil pressure. [Means for solving the problem]

[0006] The present disclosure relates to a plant cultivation device having a wall extending in a height direction and forming a storage chamber for storing soil, the device having a frame arranged to surround the outside of the wall and support the wall, and a support column connected to the frame and extending in the height direction, the wall having a plurality of component plates arranged across the storage chamber, and a connecting member arranged in the storage chamber and connecting the plurality of component plates to each other.

[0007] The wall may also be provided with a drainage port for discharging water from within the storage chamber downwardly within the storage chamber.

[0008] Furthermore, a space forming member may be provided to form a space between the drain outlet and the ground.

[0009] Furthermore, the frame may have a plurality of divided frames arranged at intervals in the vertical direction, the connecting member may support the lower ends of the walls and the lower ends of the frames in the vertical direction, and the connecting member may also serve as the space forming member.

[0010] Furthermore, a lower end of the support pillar may be in contact with the ground, and the support pillar may also serve as the space forming member.

[0011] Furthermore, the connecting member may be disposed horizontally between the upper and lower ends of the wall in the height direction.

[0012] Furthermore, a stake portion that is embedded in the ground may be provided at the lower end of the support in the height direction.

[0013] Furthermore, the drain outlet may be provided throughout the entire storage chamber when viewed from above. Effect of the Invention

[0014] The walls of the plant cultivation device of the present disclosure include a plurality of component plates arranged across the storage chamber, and have connecting members connecting the plurality of component plates together, thereby preventing the walls from tilting outward due to the pressure of the soil in the storage chamber.

[0015] Furthermore, if the wall has a drainage port for draining water from the storage chamber downward, the amount of moisture in the storage chamber can be prevented from increasing, and the wall can be prevented from tilting outward due to the water pressure in the storage chamber.

[0016] Furthermore, if a space forming member is provided to form a space between the drain outlet and the ground, a water-permeable material can be laid in the space, thereby preventing grass growing on the ground from entering the storage chamber.

[0017] Furthermore, if the frame has a plurality of divided frames spaced apart in the height direction, the connecting members support the lower ends of the walls and the frames in the height direction, and the connecting members also serve as space forming members, then it is not necessary to provide both the connecting members and the space forming members, thereby preventing an increase in the number of parts.

[0018] Furthermore, if the lower ends of the posts are in contact with the ground and the posts also serve as space forming members, there is no need to provide a connecting member and a space forming member separately, which makes it possible to prevent an increase in the number of parts.

[0019] Furthermore, when the connecting member is disposed horizontally between the upper and lower ends of the wall in the height direction, the connecting member is disposed in the soil. Therefore, the connecting member does not get in the way of workers working outside the wall. Also, the weight of the soil in the storage chamber is applied to the connecting member. Therefore, when an external force is applied that tries to inadvertently move the wall on the ground, the wall can be prevented from moving on the ground.

[0020] Furthermore, if a stake portion to be embedded in the ground is provided at the lower end of the support in the height direction, the strength with which the plant cultivation device is fixed to the ground is increased.

[0021] Furthermore, if the drainage outlet is provided throughout the entire storage chamber in a plan view of the storage chamber, drainage of the storage chamber can be ensured. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] (overview) The plant cultivation device of the present disclosure can cultivate plants, such as edible vegetables and fruits, ornamental plants, trees, etc., using the soil contained in the storage chamber. The soil may be either basic soil (culture soil) or improved soil. In the present disclosure, several specific examples included in the plant cultivation device are described with reference to the drawings.

[0024] (First concrete example) 1, 2, 3, and 4 show a first specific example of the plant cultivation device 10. The plant cultivation device 10 has a frame 11, a support 12, a wall 13, and a leg 14. When the plant cultivation device 10 is viewed from directly above, the support 12 and the wall 13 are provided inside the frame 11. When the plant cultivation device 10 is viewed from above, a storage chamber 15 is formed inside the wall 13. When the plant cultivation device 10 is viewed from above, the outer peripheral shape of the entire plant cultivation device 10 and the outer peripheral shape of the storage chamber 15 are quadrangular, for example, rectangular. The frame 11 has multiple stages of divided frames arranged at different positions in the height direction, for example, a first divided frame 16 and a second divided frame 17 in two stages. The first divided frame 16 is provided above the second divided frame 17 in the height direction A1. The height direction A1 is the vertical direction, that is, the direction in which gravity acts. The material of the first separate frame 16 and the second separate frame 17 may be any of wood, stainless steel that is resistant to rust, and the like.

[0025] Since the first division frame 16 and the second division frame 17 have the same structure and shape, for convenience, the first division frame 16 will be described as an example. The first division frame 16 has a first component part 18, a second component part 19, a third component part 20, and a fourth component part 21. When the plant cultivation device 10 is viewed in a plane, the first component part 18 and the second component part 19 are arranged in parallel, and the third component part 20 and the fourth component part 21 are arranged in parallel. When the plant cultivation device 10 is viewed in a plane, the first component part 18 and the second component part 19 have the same length, and the third component part 20 and the fourth component part 21 have the same length. The length of the first component part 18 and the second component part 19 exceeds the length of the third component part 20 and the fourth component part 21. The third component 20 is fixed to first ends of the first component 18 and the second component 19, and the fourth component 21 is fixed to second ends of the first component 18 and the second component 19.

[0026] A plurality of supports 12 are provided, and the plurality of supports 12 extend along the height direction A1 of the plant cultivation device 10. When the plant cultivation device 10 is viewed in a plan view from directly above, the plurality of supports 12 are provided standing inside the frame 11, and are arranged at intervals between each other. The upper end of each support 12 is fixed to the first divided frame 16, and the lower end of each support 12 is fixed to the second divided frame 17. The plurality of supports 12 may be made of any of the following materials: wood, rust-resistant stainless steel, etc.

[0027] The walls 13 extend in the height direction A1, i.e., the vertical direction, to form a storage chamber 15 for storing soil and the like. When the plant cultivation device 10 is viewed in a plan view from directly above, the walls 13 are disposed inside the respective supports 12. The walls 13 have a first component plate 22, a second component plate 23, a third component plate 24, and a fourth component plate 25. When the plant cultivation device 10 is viewed in a plan view, the first component plate 22 and the second component plate 23 are disposed in parallel, and the third component plate 24 and the fourth component plate 25 are disposed in parallel.

[0028] When the plant cultivation device 10 is viewed from above, the first component plate 22 and the second component plate 23 are arranged across the storage chamber 15, and the third component plate 24 and the fourth component plate 25 are arranged across the storage chamber 15. When the plant cultivation device 10 is viewed from above, the first component plate 22 and the second component plate 23 have the same length, and the third component plate 24 and the fourth component plate 25 have the same length. The length of the first component plate 22 and the second component plate 23 exceeds the length of the third component plate 24 and the fourth component plate 25. The third component plate 24 is in contact with the first end of the first component plate 22 and the second component plate 23, and the fourth component plate 25 is in contact with the second end of the first component plate 22 and the second component plate 23.

[0029] The first component plate 22 to the fourth component plate 25 are each made of a plate material. The plate materials are arranged side by side in an upright state. When the plate material is viewed from above, the outer peripheral shape of the plate is, for example, a rectangle or a square. The dimensions of the plate material alone can be set to, for example, a short side of 0.6 m and a long side of 1.8 m. Each plate material is arranged so that the short side of the plate material is arranged along the height direction A1. The first component plate 22 and the second component plate 23 are each arranged with two plate materials side by side in the longitudinal direction of the plant cultivation device 10, and the third component plate 24 and the fourth component plate 25 are each arranged with one plate material side by side in the width direction of the plant cultivation device 10. Each plate material is fixed to the support 12. The dimensions of the plate material alone are not limited to the above and can be set arbitrarily. The material of the plate material may be any of wood, rust-resistant stainless steel, fiber reinforced plastics (FRP), etc. When the storage chamber 15 is viewed from directly above in a plan view, the drainage outlet 34 is provided throughout the entire storage chamber 15. The drainage outlet 34 is provided at the lower end of the wall 13 and is connected to the storage chamber 15.

[0030] The legs 14 are provided below the frame 11, the posts 12, and the wall 13 in the height direction A1 of the plant cultivation device 10. A plurality of legs 14 are provided, and are rod-shaped members provided at intervals in the longitudinal direction of the second divided frame 17. Both ends of the legs 14 are fixed to the first constituent part 18 and the second constituent part 19 of the second divided frame 17, respectively. In other words, the legs 14 support the lower end of the second divided frame 17 and the lower end of the wall 13. The material of the legs 14 may be any of wood, rust-resistant stainless steel, etc. The legs 14 are arranged side by side on the ground 26.

[0031] When the plant cultivation device 10 is placed on the ground 26, a space (gap) 27 is formed between the storage chamber 15 and the ground 26. The height of this space 27 is determined according to the dimensions (thickness) of the legs 14. Then, before the soil 28 is poured into the storage chamber 15, a laying material 29, for example, rice husks, wood chips, etc., is laid on the lower part of the storage chamber 15. The laying material 29 has water permeability. The laying material 29 is laid to a height sufficient to fill the space 27 between the second divided frame 17 and the ground. Next, the soil 28 is poured from the storage chamber 15 onto the laying material 29. The soil 28 is poured up to near the upper end of the wall 13. After that, work such as sowing plant seeds in the soil 28 and planting plant seedlings in the soil 28 can be performed.

[0032] In the plant cultivation device 10, the pressure of the soil 28 accommodated in the accommodation chamber 15 is transmitted to the frame 11 via the wall 13 and the support 12, and the pressure is mainly received by the second divided frame 17. The first component part 18 and the second component part 19 of the second divided frame 17 are connected by the legs 14. Therefore, the first component plate 22 and the second component plate 23 can be prevented from tilting outward.

[0033] In addition, when rainwater falls on the soil 28 or when an operator supplies water on the soil 28, the water permeates the soil 28 and is discharged from the drainage outlet 34 at the bottom of the storage chamber 15. The water discharged from the drainage outlet 34 permeates into the ground 26. In addition, since there is a space 27 between the second divided frame 17 and the ground 26, a part of the water drained from the drainage outlet 34 is discharged into the space 27. Therefore, the water sweeping performance of the storage chamber 15 can be ensured. In this way, the legs 14 serve both to connect the second divided frames 17 to each other and to form the space 27. Therefore, it is not necessary to provide elements that perform each role separately. Therefore, it is possible to suppress an increase in the number of parts of the plant cultivation device 10.

[0034] Furthermore, since the top of the soil 28 is located near the upper end of the wall 13 in the height direction A1 of the plant cultivation device 10, a worker standing on the ground 26 can perform work such as sowing seeds, planting seedlings, and caring for plants without bending his / her back, thereby reducing the burden on the worker's back. Furthermore, the worker can work while sitting on the first divided frame 16, work with his / her hands on the first divided frame 16, work by placing an object on the first divided frame 16, etc. Furthermore, since the laying material 29 is laid on the lower part of the storage chamber 15, grass growing on the ground 26 can be prevented from entering the storage chamber 15.

[0035] (Second concrete example) A second specific example of the plant cultivation device 10 is shown in Figures 5 and 6. The legs 14 described in the first specific example of the plant cultivation device 10 are not provided. In a plan view of the plant cultivation device 10, the lengths of the four supports 12 arranged at the four corners exceed the lengths of the other supports 12. Therefore, in a plan view of the plant cultivation device 10, the lower ends of the four supports 12 arranged at the four corners are placed on the ground 26, forming a space 27. In other words, the four supports 12 play the role of the legs 14.

[0036] In addition, a connecting member 30 is provided to connect one support 12 and the first component plate 22 of the wall 13 to one support 12 and the second component plate 23. A plurality of connecting members 30 are provided in the storage chamber 15. The connecting member 30 has two rods and a turnbuckle 31 connecting the two rods. Furthermore, two connecting members 32 are provided to connect two supports 12 located on diagonal lines at the four corners of the plant cultivation device 10 in a plan view of the plant cultivation device 10. The connecting member 32 is provided in the storage chamber 15. The connecting member 32 has two rods and a turnbuckle 33 connecting the two rods. The connecting members 30 and 32 are horizontally disposed between the upper end and the lower end of the wall 13 in the height direction A1.

[0037] An operator can adjust the overall length of the connecting member 30 by operating the turnbuckle 31 before the soil 28 is put into the storage chamber 15, or when the soil 28 to be put into the storage chamber 15 is below the connecting members 30, 32. Therefore, when the soil 28 is put into the storage chamber 15 up to near the upper end of the wall 13, the connecting member 30 receives the pressure applied from the soil 28 to the first component plate 22 and the second component plate 23 of the wall 13. Therefore, it is possible to prevent the first component plate 22 and the second component plate 23 from tilting outward.

[0038] In addition, the worker can adjust the overall length of the connecting member 30 by operating the turnbuckle 33 before the soil 28 is put into the storage chamber 15 or when the soil 28 to be put into the storage chamber 15 is below the connecting members 30 and 32. Therefore, when the soil 28 is put into the storage chamber 15 up to near the upper end of the wall 13, the connecting member 32 receives the pressure applied from the soil 28 to the wall 13. Therefore, the first component plate 22, the second component plate 23, the third component plate 24, and the fourth component plate 25 of the wall 13 can be prevented from tilting outward. In addition, a chain may be used instead of the rod material constituting the connecting members 30 and 32. In addition, the rod material and the chain constituting the connecting members 30 and 32 are made of stainless steel or the like, which is resistant to rust.

[0039] (Third Specific Example) A third specific example of the plant cultivation device 10 is shown in Figs. 7 and 8. The length of the support 12 described in the first specific example of the plant cultivation device 10 is changed. The support 12 has a stake 12A at a portion protruding from the lower surface of the second divided frame 17. The length of the stake 12A exceeds the thickness of the leg 14. The stake 12A is driven into the ground 26, and the strength for fixing the plant cultivation device 10 to the ground 26 is ensured. In other words, the stake 12A is buried in the ground. When an external force is applied to the plant cultivation device 10 in a substantially horizontal direction, the stake 12A receives the load, so that the plant cultivation device 10 can be prevented from moving on the ground 26. The stake 12A may be provided at the lower end of the support 12 in Figs. 5 and 6 described in the second specific example of the plant cultivation device 10.

[0040] (effect) The wall 13 of the plant cultivation device 10 of the present disclosure includes a first component plate 22 and a second component plate 23 arranged across the storage chamber 15, and has legs 14 connecting the first component plate 22 and the second component plate 23. Therefore, the wall 13 can be prevented from tilting outward due to the pressure of the soil 28 in the storage chamber 15.

[0041] In addition, since the wall 13 is provided with the drainage outlet 34 that drains the water in the storage chamber 15 downward from the storage chamber 15, an increase in the amount of moisture in the storage chamber 15 can be suppressed. Furthermore, the wall 13 can be suppressed from tilting outward due to the water pressure in the storage chamber 15.

[0042] Furthermore, if the legs 14 or the stakes 12A are provided to form the space 27 between the drain outlet 34 and the ground 26, a water-permeable installation 29 can be laid in the space 27. This makes it possible to prevent grass growing on the ground 26 from entering the storage chamber 15.

[0043] Furthermore, the frame 11 has a first divided frame 16 and a second divided frame 17 arranged at an interval in the height direction A1, and the legs 14 support the lower ends of the walls 13 and the second divided frame 17 in the height direction A1, and also function as space forming members. Therefore, it is not necessary to provide a connecting member and a space forming member separately, and an increase in the number of parts can be suppressed.

[0044] Furthermore, if the lower end of the support pillar 12 is in contact with the ground 26 and the support pillar 12 also serves as a space forming member, there is no need to provide a connecting member and a space forming member separately, and therefore an increase in the number of parts can be suppressed.

[0045] Furthermore, the connecting members 30, 32 are arranged horizontally between the upper and lower ends of the wall 13 in the height direction A1, and the connecting members 32, 32 are arranged in the soil 28. This makes it possible to prevent the connecting members 32, 32 from getting in the way of workers working outside the wall 13. In addition, the weight of the soil 28 inside the storage chamber 15 is applied to the connecting members 32, 32. This makes it possible to prevent the wall 13 from moving on the ground when an external force is applied that tries to inadvertently move the wall 13 on the ground.

[0046] Furthermore, if a stake portion 12A to be embedded in the ground 26 is provided at the lower end of the support 12 in the height direction A1, the strength with which the plant cultivation device 10 is fixed to the ground 26 increases.

[0047] Furthermore, if the drainage outlet 34 is provided throughout the entire storage chamber 15 in a plan view of the storage chamber 15, the drainage properties of the storage chamber 15 can be ensured.

[0048] (supplementary explanation) In the present disclosure, instead of the elements and square timbers constituting the frame 11, the support 12, and the leg 14, single pipes used as temporary materials at construction sites may be used. The elements constituting the frame 11, the support 12, and the leg 14 may be assembled and disassembled. Means for enabling the elements constituting the frame 11, the support 12, and the leg 14 to be assembled and disassembled include bolts, nuts, connectors, brackets, and the like. The multiple divided frames may be provided in three or more stages in the height direction. Furthermore, the number of supports is not limited, and may be a single support or multiple supports. The support and the frame may be integrated into a structure. Furthermore, the height of the plant cultivation device, the length and width in a plan view of the plant cultivation device, and the like may be changed arbitrarily. In a plan view, the outer peripheral shape of the frame and the outer peripheral shape of the storage chamber are not limited to a rectangle, and may be a circle, an ellipse, a triangle, a pentagon, a hexagon, and the like. The height of the plant cultivation device, the length, width, short axis length, long axis length, diameter, etc. of the plant cultivation device in a plan view can be changed as desired. Furthermore, in a plan view of the storage chamber, the drain outlet may be structured to connect to either the entire storage chamber or a part of the storage chamber.
