Description

The present invention relates to a stand for elevated plant cultivation.

Elevated cultivation is now common because it does not require the worker to crouch as in soil cultivation, reduces the workload, and makes cultivation management easier. The same is true for raising seedlings. For such elevated cultivation, a stand is used that uses a mesh material for the top plate that supports the cultivation containers, etc. The mesh material for the stand is made of a material that is strong enough and has good breathability, such as expanded metal. A simple example is one in which expanded metal is placed on top of posts driven into the ground.

However, the conventional method of burying the support of each leg member in the ground requires a lot of effort and time to bury the metal pipe of the support straight in the ground and keep it level, which is an extremely difficult task. In addition, if the expanded metal of the net material is exposed, the outer circumference of the expanded metal can get caught during work, leading to reduced work efficiency, and there is a risk of injury from metal burrs or falling over. Special covers such as end covers and corner guards to prevent snagging are sold, but they are expensive, and installing the entire outer circumference over a large area requires considerable cost and effort. In addition, maintenance such as replacement due to deterioration is also necessary. Some expanded metals are resin-coated to make them less likely to get caught, but this is also expensive and not practical for large areas. There is also a stand where the table itself is welded with an L-shaped frame material on which the net material is placed (Patent Document 1). This is also expensive and difficult to use for large areas. It is heavy and difficult to install and move. In addition, special corner guards are required for the corners.

The present invention was developed to eliminate the above-mentioned drawbacks, and one of the objects of the present invention is to provide a platform for elevated plant cultivation that covers the outer edge of the expanded metal mesh material to ensure the safety of workers, has a simple structure, is easy to assemble and install, and can be provided at low cost.

Means for solving the problem and effects of the invention

The elevated plant cultivation stand according to the first aspect of the present invention comprises a rectangular net material extending in the longitudinal direction with a predetermined width on which a cultivation container is placed, a metal peripheral pipe provided in a position covering the periphery of the net material, a loading rod on which the net material is placed, and a plurality of support legs connected to the loading rod and arranged at intervals in the longitudinal direction of the net material. The net material is expanded metal, and the loading rod has a vertical rod extending in the longitudinal direction of the net material, and a plurality of horizontal rods arranged at intervals in the longitudinal direction of the vertical rod and extending in the lateral direction of the net material. The horizontal rods are connected to the vertical rods in a crossed position, and both ends are connected to the support legs. The lateral pipe is a metal pipe, and has a vertical pipe covering the longitudinal direction of the periphery of the expanded metal net material, and a horizontal pipe connected to the end of the vertical pipe and covering the lateral direction of the periphery of the expanded metal net material, and the vertical pipe is connected to the support legs.

According to the above configuration, the outer periphery pipe, which is provided at a position that covers the outer periphery of the net material, prevents the outer periphery of the expanded metal, which is the net material, from getting caught, ensuring the safety of the worker and improving work efficiency. The outer periphery of the expanded metal has burrs and protrusions on the cut surface, which makes it easy to get caught, and there is a risk of injury or falling during work. By using a cylindrical metal pipe for the outer periphery pipe, it becomes a smooth curve, there is no need to worry about getting caught during work, and the safety of the worker is ensured. The worker can concentrate on the work without worrying about getting caught, which contributes to improving work efficiency. The vertical rod of the loading rod supports the net material in the longitudinal direction, and the horizontal rod supports the net material in the lateral direction, and the vertical rod and the horizontal rod are connected in a crossed position, and both ends of the horizontal rod are connected to the support legs. This simple structure ensures the strength of the entire frame and enables stable support. The vertical pipe and the horizontal pipe of the outer periphery pipe are connected, and the vertical pipe is connected to the support legs, so the strength of the entire frame can be improved. The expanded metal mesh material is strong enough to support the load, and its mesh structure allows good ventilation. The material also prevents moisture from accumulating when watering plants, making it less likely to cause disease. By fixing it to the loading rod, the strength of the entire stand is increased, contributing to stable support.

In addition to the above configuration, the second aspect of the present invention relates to a trestle for elevated plant cultivation, and the corners of the outer periphery pipe can be bent by bending a metal pipe.

According to the above configuration, the corners of the outer periphery pipe are bent sections formed by bending a metal pipe, resulting in smooth curves, which similarly ensures the safety of the worker and improves work efficiency. Furthermore, by bending the metal pipe, no connectors are required, which reduces costs. By adjusting the length of the horizontal pipe to match the short side length of the net material and bending the metal pipe in advance, no length adjustment is required during assembly, making assembly easier. The connection between the bent metal pipe and the straight metal pipe allows for various combinations, making assembly easier, and standardizing parts reduces costs.

In addition to any of the above configurations, the third aspect of the present invention relates to a stand for elevated plant cultivation, in which the outer periphery of the expanded metal extends radially outward from the center of the nearest outer periphery pipe, and can be positioned below the tangent (L) direction at the intersection between the inclined surface that has an elevation angle of 45 degrees with respect to the horizontal plane and the outer periphery of the outer periphery pipe.

With the above configuration, the outer peripheral edge of the expanded metal is within a specified range, which prevents the outer peripheral edge of the expanded metal from getting caught, ensuring the safety of workers and improving work efficiency.

The fourth aspect of the present invention relates to a trestle for elevated plant cultivation, which, in addition to any of the above configurations, has a vertical rod that is a U-shaped member having bent portions on both sides of a flat surface extending in the longitudinal direction.

With the above configuration, the U-shaped member, which has bent sections on both sides of the flat surface extending in the longitudinal direction, has strength due to the bent sections on both sides of the flat surface, and supports the mesh material from below in the longitudinal direction, while the horizontal rods are cross-connected to the vertical rods, maintaining the strength of the entire frame and enabling stable support. The mesh material and vertical rods can be easily fixed by using the flat surface extending in the longitudinal direction of the metal frame and placing screw heads or washers on the intersections of the expanded metal mesh. Fixing can be done from above the mesh material, making assembly easy.

The fifth aspect of the present invention relates to a stand for elevated plant cultivation, which has any of the above configurations, and in addition has a container set gap for placing a cultivation container between one of the vertical pipes and the side edge of the netting material. The horizontal rod has a stepped shape, and has an upper horizontal section that supports the netting material, and a lower mounting section for placing a cultivation container placed in the container set gap. The horizontal section and mounting section are connected via a stepped bend section, and the horizontal section, mounting section, and stepped bend section are composed of a single metal pipe.

According to the above configuration, the cultivation container placed in the container set gap does not need to have a special shape. In addition to general planters, various types and shapes of containers can be used. Since the container set gap is provided between the vertical pipe and the side edge of the net material, the container fits well. Since the mounting part is located lower than the horizontal part, the center of gravity of the stand is lowered and the container can be stably supported. In addition, the type, shape, and size of the cultivation container placed on the net are not limited, and it is possible to respond to various cultivation methods such as moving and arranging the cultivation container according to the growth state. The horizontal rod has a horizontal part, a mounting part, and a step bending part, and is composed of a single metal pipe. Since the step bending part is made by bending the metal pipe, positioning or fine adjustment of the height difference is not required during assembly, and assembly is easy. In addition, there is no need to connect members of different lengths with joints, which reduces the number of parts and leads to cost reduction. By providing a step between the top surface of the upper netting material and the top of the lower loading section, for example, when cultivating plants of different heights, different growth rates, different harvest times, or different types of plants, the effects of shading from larger plants can be reduced and an appropriate environment can be provided, making it easier to observe the cultivation status and manage the cultivation without the large plants getting in the way of work.

The sixth aspect of the present invention relates to a stand for elevated plant cultivation, which, in addition to the fifth configuration, is adapted to cultivate plants that grow offspring from parent plants, and the upper surface of the netting material can be used as a cultivation area for offspring, and the container set gap can be used as a cultivation area for parent plants, in which a parent container for cultivating the parent plants is placed.

According to the above configuration, an appropriate environment can be provided when cultivating a plant that grows by extending runners, such as strawberries. By arranging the parent plant container in a lower position than the cultivation area of the child plants, the runners can extend horizontally from the parent plant container placed in the gap between the container sets along the net material supported by the horizontal part that is one step higher than the mounting part (horizontal cultivation). This horizontal cultivation can avoid the problems of vertical cultivation that cause the runners to hang down. The runners can extend without stress from moisture and sunlight, and it is easy to manage the cultivation so that the runners do not get tangled. Strict water management is also not required. It is possible to avoid the risk of physical damage caused by touching or rubbing the edge of the planter of the parent plant container, heat, etc. There is no need to place the parent plant container at a high position such as 2m, and the parent plant of strawberry, which is sensitive to heat, is not exposed to a harsh environment, and measures such as air conditioning and sunlight are not required. By making the upper surface of the net material the cultivation area of the child plants, the child plant containers can be freely arranged and moved, making it easy to manage the cultivation. By positioning the parent plant cultivation area at the bottom, the height of the parent plants and parent plant containers does not get in the way of work, and plant condition observation and cultivation management can be easily performed from the parent plant container side of the stand.

The seventh aspect of the present invention relates to a trestle for elevated plant cultivation, which, in addition to the fifth or sixth configuration described above, allows the height difference (H) between the mounting portion and the horizontal portion to be 4 cm to 20 cm.

With the above configuration, the height at which the parent plant container and the seedling container are installed can be adjusted to match the height of a planter or the like that is generally used for the parent plant container and the height of a plastic pot or the like that is used for the seedling container, and runners can grow horizontally from the parent plant. The runners are not subjected to unnecessary stress such as moisture or sunlight, and it is easy to organize them so that they do not become tangled, and physical obstacles caused by the edges of the planter can be avoided, providing a good growing environment for the runners.

In addition to any of the above configurations, the eighth aspect of the present invention relates to a stand for elevated plant cultivation, and the support legs are metal pipes, which have a horizontal leg portion that is placed on the ground and vertical legs that are connected to both ends of the horizontal leg portion via bent portions, and the horizontal leg portion, vertical leg portion, and bent portion can be made of a single metal pipe that has been bent.

With the above configuration, the support legs have a larger contact area with the ground than if they were supported by the bottom surface of a single support pillar, preventing them from sinking into the ground. Of course, there is no need to drive the pillars into the ground. In addition, the horizontal legs are of a predetermined length that is pre-adjusted to the short side of the stand, and the vertical legs are attached to both ends via bent sections, and a single metal pipe is bent, so there is no need to adjust the short side length of the stand, making assembly easy and contributing to lower costs.

The ninth aspect of the present invention relates to a stand for elevated plant cultivation, which, in addition to any of the above configurations, further comprises a first connector connecting the upper part of the support leg to the end of the horizontal rod, and a second connector connecting the vertical pipe to the upper end of the support leg, and the vertical pipe is connected to the horizontal rod via the second connector, the support leg, and the first connector, and the vertical rod is fixed onto the horizontal rod, and an expanded metal mesh material is fixed onto the vertical rod, so that the peripheral pipe can be positioned to cover the outer periphery of the expanded metal.

With the above configuration, first, the upper part of the support leg and the end of the horizontal rod can be connected and fixed by the first connector, and by fixing them together, the ends of the support leg and the horizontal rod that are perpendicular to each other can be connected and fixed. Next, the vertical pipe and the upper end of the support leg can be connected and fixed by the second connector, and by fixing them together, the upper ends of the vertical pipe and the support leg that are perpendicular to each other can be connected and fixed. Both of these methods make assembly easier and contribute to reducing costs.

With the above configuration, the vertical pipe is connected to the horizontal rod via the second connector, the support leg, and the first connector, making it easy to connect and fix the vertical pipe to the horizontal bar, and easy to assemble.

In addition to any of the above configurations, the tenth aspect of the present invention relates to a stand for elevated plant cultivation, which further includes a vertical vibration prevention pipe connected to the support legs and the support rod, and the vertical vibration prevention pipe has a horizontal pipe section extending in the longitudinal direction of the netting material and a brace section connected to the horizontal pipe section via an acute angle bend, and the tip of the horizontal pipe section can be connected to the lower end of the support legs, and the tip of the brace section can be connected to the horizontal rod.

The above configuration ensures the strength of the entire stand and enables stable support against longitudinal (vertical) shaking and vertical forces of the stand once it has reached a certain length.

The elevated plant cultivation rack according to the eleventh aspect of the present invention has any of the above configurations, and further has a metal pipe with an outer diameter of 18.6 mm to 19.6 mm and a wall thickness of 0.9 mm to 1.5 mm.

The above configuration allows the use of metal pipes of general-purpose standards, reducing material costs and providing an inexpensive stand. In addition, by using metal pipes of the same diameter and thickness, parts and materials can be standardized, the same connectors can be used, and manufacturing costs can be reduced. Parts can also be replaced easily and at low cost. Metal pipes of this size are inexpensive, lightweight, and strong enough to be used as stands for plant cultivation. For example, they are used for general purposes, such as in small vinyl greenhouses and Viet Cong for spring ginseng, and are commercially available at low cost at hardware stores and other stores, making them easy to obtain.

[Embodiment 1]

Fig. 1 is a perspective view showing a rack 3 for elevated cultivation according to a first embodiment of the present invention. The rack 3 for elevated cultivation shown in Fig. 1 includes a rectangular net material 1 extending in the longitudinal direction with a predetermined width on which a cultivation container 24 is placed, a metal peripheral pipe 2 provided at a position covering the periphery of the net material 1, a loading rod 4 on which the net material 1 is placed, and a plurality of support legs 5 connected to the loading rod 4 and arranged at intervals in the longitudinal direction of the net material 1. The net material 1 is an expanded metal 1a, and the loading rod 4 includes a vertical rod 4a extending in the longitudinal direction of the net material 1, and a plurality of horizontal rods 4b arranged at intervals in the longitudinal direction of the vertical rod 4a and extending in the lateral direction of the net material 1. The horizontal rods 4b are connected to the vertical rods 4a in a crossed position, and both ends are connected to the support legs 5. The outer periphery pipe 2 is a metal pipe 8 having a vertical pipe 2a that covers the longitudinal direction of the outer periphery of the expanded metal 1a which is the mesh material 1, and a horizontal pipe 2b that is connected to the end of the vertical pipe 2a and covers the shorter direction of the outer periphery of the expanded metal 1a which is the mesh material 1, and the vertical pipe 2a is connected to the support leg 5.
(Expanded metal 1a)

As shown in FIG. 1, expanded metal 1a is used as the net material 1. Expanded metal 1a has sufficient strength as a net material to support the object, and has good breathability due to its mesh shape. The material does not accumulate moisture supplied to plants by watering, making it less likely to cause disease. The raised surface of the expanded metal 1a acts as a non-slip surface for the cultivation container 24, contributing to ease of cultivation management and work. The intersections of the mesh of the expanded metal 1a can be easily fixed to the supporting member with flat screws or screws with washers. In addition, by adding or cutting the expanded metal 1a together with other members, the length of the longitudinal direction (vertical direction) and the transverse direction (horizontal direction) of the stand 3 can be adjusted to the size required by the user. The expanded metal 1a is characterized by its manufacturing method, and is a mesh-like metal plate made by expanding a single metal plate while making staggered cuts, and then forming the cuts into a diamond or tortoiseshell shape. Because the plate is stretched and cut, it is lighter than a metal plate, has strength because there are no seams in the net and the applied load is distributed, has good breathability due to its mesh shape, can be cut, and has ridges on the surface that prevent items from slipping, all of which are features that can be utilized in the present invention. There is no limit to the type of cultivation container 24 that can be placed on the expanded metal 1a, and cultivation containers 24 of various types, shapes, and sizes can be used.

The standard size of the expanded metal 1a of the net material 1 is, for example, standard XS42, with a width of 914 mm, a length of 1829 mm, a mesh size of 22 mm, a mesh size of 50.8 mm, a plate thickness of 2.3 mm, and a pitch of 2.5 mm. There are various other products according to the mesh size. The expanded metal 1a has an abacus pattern and a folded pattern depending on the direction of the mesh, and either can be used. However, since the expanded metal 1a is manufactured by cutting and stretching a metal plate, there are individual differences in the way the material stretches, and errors can occur depending on the cutting location and method. Depending on the length, the diamond pattern may be shifted by half a mesh. Taking these into consideration, the outer peripheral pipe 2 needs to be positioned so that it can cover the outer peripheral edge of the expanded metal 1a. As for the vertical and horizontal sizes, a gap can be provided in advance while taking into consideration the possibility of certain errors while assuming the standard size. During assembly, the installation position can be finely adjusted when fixing the mounting rod 4 supporting the expanded metal 1a, and play can also be adjusted by the first connector 11 and the third connector 13.
(Outer pipe 2)

As shown in FIG. 1, the outer periphery pipe 2 is a metal pipe 8 provided in a position to cover the outer periphery of the net material 1, and is formed by connecting a vertical pipe 2a and a horizontal pipe 2b. The vertical pipe 2a mainly covers the longitudinal direction of the outer periphery of the net material 1, and the horizontal pipe 2b mainly covers the transverse direction of the outer periphery of the net material 1. As shown in the enlarged view of FIG. 1, if the burrs on the outer periphery edge of the expanded metal 1a of the net material 1 are exposed, when a worker passes through an aisle or works, his/her clothes may get caught on the outer periphery of the net material, and his/her hands and feet may come into contact with the outer periphery, causing injury or causing a fall. This is all the more true when working in a leaning forward position. Therefore, the outer periphery pipe 2 is designed to cover the outer periphery of the expanded metal 1a of the net material 1.

When the outer periphery pipe 2 covers the outer periphery of the expanded metal 1a, which is the net material 1, it means that the nearest outer periphery pipe 2 is positioned so that there is no risk of it getting caught on the burrs on the outer periphery of the expanded metal 1a. Not only when the center of the nearest outer periphery pipe 2 is positioned almost directly beside the outer periphery of the expanded metal 1a (Figure 2), but also when it is slightly shifted up or down, it can be said to be covered by the outer periphery pipe 2 as long as it is located within a range where there is no risk of it getting caught on the outer periphery of the expanded metal 1a. The outer periphery of the expanded metal 1a and the outer periphery pipe 2 can be in contact with each other, or a gap can be provided between them. The outer periphery pipe 2 is positioned in a position where there is no risk of it getting caught, taking into account the manufacturing error, cutting error, etc. of the expanded metal 1a.

Specifically, as shown in FIG. 3A, the outer peripheral edge of the expanded metal 1a can be arranged below the tangent (L) direction at the intersection of the inclined surface that extends radially outward from the center of the nearest outer peripheral pipe 2 and the outer peripheral surface of the outer peripheral pipe 2 at an elevation angle of 45 degrees to the horizontal plane. Also, as shown in FIG. 3B, the height (h) of the upper end of the outer peripheral edge of the expanded metal 1a can be lower than the height (h1) of the upper end of the nearest outer peripheral pipe 2 and higher than the height (h2) of the lower end. By arranging the outer peripheral edge of the expanded metal 1a, which is the net material 1, in this range, the outer peripheral pipe 2 can cover the outer peripheral edge of the expanded metal 1a. This prevents the clothes and hands of the worker from touching the burrs and snags on the outer peripheral edge of the expanded metal 1a when working or passing through a passageway.

The outer periphery pipe 2 is a cylindrical metal pipe 8, so that the outer periphery of the expanded metal 1a, which is the mesh material 1, can be covered by the smooth cylindrical curve of the outer periphery pipe 2. This means that there is no need to worry about getting caught during work, ensuring the safety of the worker and allowing them to concentrate on their work, improving work efficiency.

If the outer diameter of the outer periphery pipe 2 made of metal pipe 8 is too small, the strength of the frame will decrease and the placement to cover the outer periphery of the expanded metal 1a will be easily restricted. Conversely, if the outer diameter is too large, the weight will be large, assembly will be time-consuming, and it will not be possible to manufacture it inexpensively. Therefore, taking these factors into consideration, the outer diameter of the metal pipe 8 used for the outer periphery pipe 2 is set to 15.0 mm to 25.0 mm, preferably 18.6 mm to 19.6 mm. The outer diameter and thickness of the metal pipe 8 will be described in detail later.

The corners of the outer peripheral pipe 2 can be bent to bends 2c formed by bending the metal pipe 8. As with the above, there is no risk of getting caught in the corners of the outer peripheral pipe 2 during work, ensuring the safety of the worker and improving work efficiency. In addition, by bending the metal pipe 8, no connector is required at that part, which reduces costs. In order to prevent the strength of the metal pipe 8 from being significantly reduced by bending, it is preferable that the bent parts 2c are bent with a curvature radius of 1.5 times or more the diameter of the metal pipe 8. The curvature radius of the bent parts 2c is preferably 1.5 to 5 times, more preferably 2 to 4 times, the diameter (outer diameter) of the metal pipe 8. For example, when the outer diameter of the metal pipe 8 is 19 mm, the bent parts are preferably bent with a curvature radius of 28.5 to 95 mm, more preferably 38 to 76 mm. This is also true for other members to which the metal pipe 8 is bent.

It is conceivable to cover the outer periphery of the mesh material 1 with an L-shaped frame material, but it is difficult to bend the L-shaped frame material into a smooth curve. If the L-shaped frame material bends or opens up, it will not maintain its strength and may become susceptible to rust or corrosion due to deterioration over time. When assembling L-shaped frame materials into a roughly rectangular shape, the corners need to be connected by joints or welding, and corner guards are also required to cover the corners. In this regard, the metal pipe 8 is cylindrical in shape, so there is no need to worry about it getting caught on the worker's hands or clothes when they come into contact with it. In addition, since it can be bent into a smooth curve even at corners, it is said to be ideal as a snag prevention pipe.

The outer pipe 2 can be a combination of a metal pipe 8 bent in one or two places and a straight metal pipe 8. For example, as shown in FIG. 1, the horizontal pipe 2b of the metal pipe 8 bent in an approximately U-shape can be connected to both ends of the vertical pipe 2a of the two straight metal pipes 8 arranged on both sides of the net material 1. In addition, the horizontal pipe 2b or the vertical pipe 2a can be made by connecting two metal pipes 8 bent in an approximately L-shape at only one place of the metal pipe 8. The metal pipe 8 bent in an approximately L-shape can be used for the horizontal pipe 2b and the vertical pipe 2a. The metal pipe 8 bent in an approximately L-shape may be connected to the straight metal pipe 8. The vertical pipe 2a of the straight metal pipe 8 and the horizontal pipe 2b of the straight metal pipe 8 can also be connected with a bent connector or an approximately L-shaped connector. Various combinations are possible, assembly is easy, and costs can be reduced by sharing parts. For example, if the metal pipe 8 is bent into an approximately U-shape to form the horizontal pipe 2b, length adjustment is unnecessary and assembly is easy. If the metal pipe 8 is bent into an approximately L-shape at only one point and two L-shaped metal pipes are connected to form the horizontal pipe 2b, if the width of the mesh material 1 in the short direction differs from the standard specified width, the difference in width can be accommodated by replacing only one of the connected L-shaped metal pipes, and costs can be reduced by standardizing parts while meeting user needs.

The size of the outer pipe 2 is preferably set to match the standard size of the expanded metal 1a, for example, the width is about 90 cm to 100 cm, and the vertical length can be adjusted to the length of the joined expanded metal 1a. However, the vertical and horizontal lengths can also be adjusted by cutting and adding to the expanded metal 1a.

When bending the metal pipe 8, it is preferable that no dents are created on the inside or outside of the bent portion 2c. If dents are created on the inside or outside of the bent portion 2c or if the bending process does not result in a smooth curve, it will be difficult to maintain the strength of the metal pipe 8, and there is a risk that rust or damage will occur due to deterioration over time. The same applies when bending the metal pipe 8 for other components.

Bending the metal pipe 8 allows the metal pipe 8 to draw a smooth curve while maintaining its roughly cylindrical shape, preventing the mesh material 1 from getting caught on its outer periphery. It also has the advantage of being simple in structure, easy to assemble, and low-cost because no welding or connectors are required. The same applies when bending the metal pipe 8 for other components.

The outer perimeter pipe 2 is connected to the horizontal pipe 2b and the vertical pipe 2a, and surrounds the entire perimeter of the net material 1 in a roughly rectangular shape. By connecting and fixing the outer perimeter pipe 2 to the support legs 5, and by connecting and fixing the outer perimeter pipe 2 to the loading rod 4 via the support legs 5, the outer perimeter pipe 2 that surrounds the stand 3 in a roughly rectangular shape functions as part of the frame of the stand 3, and the strength of the entire stand 3 can be improved. The strength of the entire stand 3 can be improved without adding separate reinforcing members, leading to weight reduction and cost reduction.

Although not shown, when laying a sheet, net, etc. on the netting material 1, it is necessary to prevent the sheet, etc. from shifting out of position and being turned over by the wind. Since the outer periphery pipe 2 is a metal pipe 8, it is possible to use fasteners that fit the outer diameter of the metal pipe 8, which is easy and inexpensive.

Although not shown, for example, the inner diameter or outer diameter of one of the connecting parts of the vertical pipe 2a and the horizontal pipe 2b can be fitted into the outer diameter or inner diameter of the other. The outer diameter of one of the connecting parts of the vertical pipe 2a and the horizontal pipe 2b can be made smaller to match the inner diameter of the other, or the inner diameter of one of the connecting parts can be made larger to match the outer diameter of the other. The connecting part can also be tapered. Also, metal pipes 8 of different sizes can be used so that the inner diameter of one of the connecting parts of the vertical pipe 2a and the horizontal pipe 2b fits into the outer diameter of the other, or a separate member called a connector that connects the pipes can be used. By providing a connecting part, the connecting parts can be easily connected and fixed. However, the connecting method is not limited to this method. Also, the connecting part can be fixed in various ways, such as by screwing, pinning, locking parts, and fastening metal fittings (belts), and the method is not limited. Other methods include using the elastic force of a spring or similar to that used for an umbrella to fit a plate, wire, or ball-shaped locking protrusion into a locking hole, turning a fixing ring to tighten a fixing screw like in an extendable walking stick, or using a plunger. Screw fastening is cheap, simple, and provides a strong fix, while methods that use the elastic force of a spring or similar can be easily connected by simply fitting the item into a specified position.
(Loading rod 4)

As shown in Fig. 1, the support rod 4 has a vertical rod 4a extending in the longitudinal direction of the frame 3 and a horizontal rod 4b extending in the lateral direction of the frame 3. The vertical rod 4a and the horizontal rod 4b are cross-connected to support the expanded metal 1a of the mesh material 1. As shown in Fig. 2, by arranging the vertical rod 4a on the horizontal rod 4b, the vertical rod 4a can directly support the mesh material 1 of the expanded metal 1a in the longitudinal direction. However, although not shown, the horizontal rod 4b can also be arranged on the vertical rod 4a.

The vertical rod 4a is a support rod 4 that is passed through the longitudinal direction of the stand 3, and maintains the longitudinal strength of the stand 3 and stably supports the stand 3 together with the horizontal rod 4b. It is preferable to use multiple vertical rods 4a. As shown in FIG. 1, for example, by passing three vertical rods 4a under the net material 1, the expanded metal 1a of the net material 1 and the cultivation container 24 loaded on it can be stably supported. Since the expanded metal 1a is about 90 cm x 180 cm in size and has a certain weight, passing the vertical rods 4a near both ends and near the center of the short side of the net material 1 can prevent sagging and keep the net material 1 flat. Since the net material 1 is in a flat state, the cultivation container 24 on the net material 1 is stable, making cultivation management easy, and it is easy to place the expanded metal 1a of the net material 1 in a predetermined position where the outer periphery of the expanded metal 1a is covered by the outer periphery pipe 2.

The vertical rod 4a in FIG. 2 is a U-shaped member 20 having bent portions on both sides of a flat surface extending in the longitudinal direction. The U-shaped member 20 is made of metal, and has strength due to the bent portions on both sides of the flat surface, and can support the expanded metal 1a from below and maintain the longitudinal strength of the entire frame 3. The bent portions of the U-shaped member 20 can be angled not only in a direction substantially perpendicular to the flat surface, but also in a direction narrowing in an inverted V shape from both sides of the flat surface (FIG. 2), or in a direction widening in an V shape from both sides of the flat surface. As shown in FIG. 2, the strength of the U-shaped member 20 can be further improved by having a bend on the outside or inside. The U-shaped member 20 shown in FIG. 2 has a flat surface, and by arranging this flat surface on the surface facing the expanded metal 1a, the expanded metal 1a can be stably supported, and by applying a flat screw head or a washer to the intersection of the mesh of the expanded metal 1a, the expanded metal 1a and the vertical rod 4a can be easily fixed. During assembly, the rods can be screwed from above, making assembly easy. The vertical rods 4a and horizontal rods 4b can be fixed to the expanded metal 1a together by screwing or the like, or they can be fixed to the expanded metal 1a separately. However, the method of fixing the expanded metal 1a of the net material 1 to the loading rod 4 is not limited to this. Metal pipes 8 can be used for the vertical rods 4a, as well as other members such as the outer periphery pipe 2 and the support legs 5. In this case, if metal pipes 8 of the same diameter and thickness are used, the members can be standardized, and costs can be reduced. In this case, ties, U-shaped metal fittings, etc. can be used for fixing. Metal pipes of different sizes can also be used.
(Horizontal rod 4b)

As shown in Fig. 1, the horizontal rods 4b are provided at a predetermined interval in the longitudinal direction of the pedestal 3, and are support rods 4 that pass through the pedestal 3 in the lateral direction, maintaining the strength of the pedestal 3 in the lateral direction and stably supporting the pedestal 3 together with the vertical rods 4a. The horizontal rods 4b connected to the support legs 5 stably support the entire pedestal 3 together with the vertical rods 4a. The horizontal rods 4b are connected and fixed to the support legs 5 to form a substantially rectangular shape and stably support the pedestal 3. By setting the length of the horizontal rods 4b together with the horizontal pipes 2b of the periphery pipe 2 to a predetermined length that matches the width of the pedestal 3 in the lateral direction, length adjustment is not required, and the pedestal 3 can be easily assembled. The horizontal pipes 2b of the periphery pipe 2 and the horizontal rods 4b can also be made of a common member.
(Support leg 5)

As shown in FIG. 1, the support leg 5 can be a metal pipe 8 having a horizontal leg 5b that is installed on the ground and a vertical leg 5a that is connected to both ends of the horizontal leg 5b via a bent portion 5c. By bending a single metal pipe 8, the horizontal leg 5b, the vertical leg 5a, and the bent portion 5c can be formed. Since the horizontal leg 5b is in contact with the ground to support the stand 3, it is not necessary to first drive the support into the ground. It is also possible for each of the support legs 5 to be a support for an independent metal pipe 8. However, the use of a metal pipe 8 bent into an approximately U-shape provides a larger area of contact with the ground for the support leg 5, and can prevent the support leg 5 from sinking into the ground, compared to when each independent metal pipe 8 is used as a support. By bending the horizontal leg 5b in advance to match the width of the short side of the net material 3, the horizontal leg 5b is set to a predetermined length, and the vertical leg 5a is also set to a predetermined height, so that adjustment of the width and height of the support leg 5 is not required during assembly, making it easier to assemble the stand 3. In addition, by bending a single metal pipe 8 into an approximately U-shape, no joint parts are required, and support legs can be created without the hassle of connecting them, resulting in lower costs.

As shown in FIG. 2, the height of the net material 1 can be adjusted by changing the height of the horizontal rod 4b connected to the vertical leg 5a of the support leg 5. This can be adjusted to suit the gender, physique, age, and preferences of the worker, but is set to, for example, 60 cm to 130 cm, preferably 70 cm to 120 cm, and more preferably 80 cm to 110 cm.

Although not shown, the horizontal leg 5b and the vertical leg 5a, which are bent into an approximately U-shape, can be separate members and connected to form the support leg 5. Also, the support leg 5 or the horizontal leg 5b and the side pipe 2b of the outer periphery pipe 2 can be made into a common member, for example, a metal pipe 8 bent into an approximately U-shape.

Although not shown, the support leg 5 can be made by connecting two metal pipes 8 that have been bent into an approximately L-shape at only one location. If the width of the short side of the stand 3 differs from the standard specified width, this can be accommodated by replacing only one of the connected L-shaped metal pipes 8, meeting user needs while reducing costs by standardizing parts.

Although not shown, it is also possible to provide a through hole in the horizontal leg 5b of the support leg 5 and drive a pin or the like through the through hole into the ground to fix the support leg 5 to the installation surface. This can further improve the stable support of the stand 3. Also, the horizontal leg can be fixed to the ground with a U-shaped pin or the like without providing a through hole.
(First connector 11)

As shown in FIG. 4, the upper part of the support leg 5 and the end of the horizontal rod 2b are connected to each other via a first connector 11. For example, the first connector 11 can have a first U-shaped bent portion 11a that is bent in a U shape along the surface of the support leg 5, and a first connecting piece 11b that is connected to both ends of the first U-shaped bent portion 11a and connected to the end of the horizontal rod 4b. The first U-shaped bent portion 11a and the first connecting piece 11b are made of a single metal plate, and the first U-shaped bent portion 11a is connected to the support leg 5, and the first connecting piece 11b is connected to the end of the horizontal rod 4b. However, the first connector 11 is not limited to this structure and shape. The first connector 11 can be fixed by various methods such as screws, pins, locking parts, and fasteners (belts), and the method is not limited. By providing the first connector 11, the end of the horizontal rod 4b and the vertical leg 5a of the support leg 5 can be easily connected and fixed. This makes assembly easy and leads to low costs.
(Stopper mechanism 6)

As shown in FIG. 4, the support leg 5 can be provided with a stopper mechanism 6 for identifying the connection position of the first connector 11. The stopper mechanism 6 can also be provided on the first connector 11 side. The presence of the stopper mechanism 6 makes it possible to easily position and fix the support leg 5 and the horizontal rod 4b. This facilitates assembly and reduces costs. As the stopper mechanism 6, for example, in addition to simply providing screw holes in the first connector 11 and the vertical leg 5a in advance to fix the first connector 11 with a screw, it is also possible to provide a locking part on the vertical leg 5a side and fit the first connector 11 into the hole, use a metal pipe 8 with a stepped part, provide a step with a cylindrical fixture, a band fixture, or a stopper that matches the outer diameter of the metal pipe 8, or provide a mark. However, the present invention is not limited to these methods, and includes a method that serves as a marker for the connection position of the first connector 11 when connecting the horizontal rod 4b to the support leg 5.
(Second connector 12)

As shown in FIG. 4, the upper ends of the vertical pipe 2a and the support leg 5 are connected to each other via the second connector 12. For example, the second connector 12 can have a second U-shaped bent portion 12a formed by bending the vertical pipe 2a in a U-shape along its surface, and a second connecting piece 12b connected to both ends of the second U-shaped bent portion 12a and connected to the upper end of the support leg 5. The second U-shaped bent portion 12a and the second connecting piece 12b are made of a single metal plate, and the second U-shaped bent portion 12a is connected to the vertical pipe 2a, and the second connecting piece 12b is connected to the upper end of the support leg 5. However, the second connector 12 is not limited to this structure and shape. The second connector 12 can be fixed by various methods such as screws, pins, locking parts, and fasteners (belts), and the method is not limited. By using the second connector 12, the upper ends of the vertical pipe 2a and the support leg 5 can be easily connected and fixed. Assembly is easy, leading to lower costs. When using metal pipes 8 of the same diameter and thickness, the same connector can be used for the first connector 11 and the second connector 12. Components can be standardized, leading to lower costs.

As shown in Fig. 2 and Fig. 4, the end of the horizontal rod 4b and the upper part of the support leg 5 are connected via a first connector 11, and the upper end of the vertical pipe 2a and the support leg 5 are connected via a second connector 12. The first connector 11 and the second connector 12 are connected via the support leg 5, and the vertical pipe 2a is connected to the horizontal rod 4b via the second connector 12, the support leg 5, and the first connector 11. The vertical rod 4a can be fixed on the horizontal rod 4b, the mesh material 1 of the expanded metal 1a is fixed on the vertical rod 4a, and the peripheral pipe 2 is arranged in a position covering the outer periphery of the expanded metal 1a. When a U-shaped member 20 is used for the vertical rod 4a, the height from the top surface of the flat surface of the U-shaped member 20 to the installation surface of the U-shaped member 20 and the horizontal rod 4b is made lower than the diameter of the vertical pipe 2a, so that the peripheral pipe 2 can be easily arranged in a position covering the outer periphery of the expanded metal 1a. As shown in Fig. 3B, the height (h) of the upper end of the outer periphery of the expanded metal 1a can be easily arranged at a position lower than the height (h1) of the upper end of the nearest outer periphery pipe 2 and higher than the height (h2) of the lower end, and fine adjustment of the height is not necessary, making assembly easy. Although not shown, when a metal pipe 8 is used for the vertical rod 4a, it is necessary to adjust the vertical pipe 2a of the outer periphery pipe 2 at the connection position of the first connector 11 so that it is located in a position that covers the outer periphery of the expanded metal 1a, and it is preferable to use a stopper mechanism 6 or the like.
(Third connector 13)

As shown in FIG. 4, the ends of the vertical pipes 2a can be connected to each other via a third connector 13. For example, the third connector 13 can be a cylindrical connector that connects metal pipes 8. A cylindrical connector having an inner diameter that matches the outer diameter of the metal pipe 8, or a connector having an outer diameter or a connecting piece that matches the inner diameter of the metal pipe 8 can be used. However, the third connector 15 is not limited to this configuration and shape. By adding vertical pipes 2a made of metal pipes 8 located on both sides of the longitudinal direction of the pedestal 1 using the third connector 13 that connects the vertical pipes 2a, the longitudinal length of the pedestal 1 can be easily adjusted according to the user's needs. The pedestal 1 of a predetermined length can be created in units, and multiple vertical pipes 2a connected via the third connector 13 can be arranged on both sides of the pedestal 1, thereby connecting the units of the pedestal 1 to each other. Cost reduction can be achieved by sharing parts and assembly processes.
(Metal pipe 8)

In the elevated cultivation stand 3 of the present invention, metal pipes with an outer diameter of 18.6 mm to 19.6 mm and a wall thickness of 0.9 mm to 1.5 mm can be used for the outer pipe 2, the loading rod 4, and the support legs 5. By using metal pipes 8 of the same diameter and thickness, the components can be standardized, reducing costs. The first connector 11 and the second connector 12 can be standardized. In elevated cultivation stands used in greenhouses, the strength of metal pipes used in large greenhouses is usually not required, and a metal pipe 8 with an outer diameter of 19.1 mm and a wall thickness of 1.2 mm (standard size) used in small greenhouses is sufficient. This metal pipe 8 is inexpensive, easily available, lightweight, and has sufficient strength for the stand 3 of the present invention, and can also be bent.

However, in the present invention, other metal pipes, such as metal pipes with a larger outer diameter and thicker walls, can also be used. Metal pipes that are not bent can be not only round pipes, but also square pipes. Pipes made of different materials can also be used. Also, different metal pipes can be used in different parts or in parts, providing a stronger elevated cultivation stand.

By using metal pipes 8 of the same diameter and thickness, the components can be standardized, and costs can be reduced. By bending the metal pipes 8, connecting components are not required for the horizontal pipes 2b, the support legs 5, and the vertical vibration prevention pipes 16, and the number of parts is reduced, resulting in cost reduction. In addition, the simple structure and easy assembly in a short time can reduce construction costs. If the farmers themselves can install the kits, costs can be further reduced. In addition, when replacing deteriorated or defective parts, the commonality of parts, the small number of parts, and the inexpensive and easily available parts are advantageous in terms of cost. Another advantage is that the structure is simple, and farmers themselves can easily manage and replace them. In fact, deterioration of parts and other items is unavoidable, and even in a controlled environment inside a vinyl greenhouse, management and replacement of parts and components may occur periodically.
[Embodiment 2]

Fig. 5 is a schematic perspective view showing a rack 30 for elevated cultivation according to a second embodiment of the present invention. In the rack 30 for elevated cultivation shown in Fig. 5, a container set gap 10 for arranging the cultivation container 24 is formed between one vertical pipe 2a and a side edge of the net material 1. The horizontal rod 4b has a stepped shape and has a horizontal part 4c for supporting the upper net material 1 and a mounting part 4e for mounting the cultivation container 24 arranged in the container set gap 10 in the lower part. The horizontal part 4c and the mounting part 4e are connected via a stepped bend part 4d, and the horizontal part 4c, the mounting part 4e and the stepped bend part 4d are formed of a single metal pipe 8.
(Container set gap 10)

Figure 6 is a schematic perspective view showing the state in which the horizontal rods formed by bending the metal pipes shown in Figure 5 are connected. As shown in Figures 5 and 6, a container set gap 10 is formed between one of the vertical pipes 2a and the side edge of the net material 1, and a cultivation container 24 is placed in the container set gap 10. As shown in Figure 7, the horizontal rod 4b has a stepped shape and has a horizontal part 4c located on the underside of the net material 1 and a mounting part 4e located below the horizontal part 4c and on which the cultivation container 24 placed in the container set gap 10 is placed. As also shown in Figure 7, a bottom support bar 4f is connected to the top of the mounting part 4e to support the cultivation container 24 placed in the container set gap 10.

The width (W1) of the container set gap 10 can be set to an optimal width according to the cultivation container 24 to be installed, but is preferably set to about 10 to 35 cm, for example, and more preferably set to about 14 to 25 cm to match the width of a commonly used planter. The height difference (H) between the mounting portion 4e and the horizontal portion 4c in the container set gap 10 can be set to match the height of the cultivation container 24 within the range of the maximum height of the stand 30 (vertical leg portion 5a), but is preferably set to about 3 cm to 25 cm, for example, and more preferably set to about 4 cm to 15 cm to match the height of a planter used in a commonly used cultivation container 24.

The cultivation container 24 placed in the container set gap 10 does not need to have a special shape. It is not limited to a general planter, and various types and shapes of cultivation containers 24 can be used, such as polystyrene foam boxes, plastic pots, vinyl bags, and nonwoven bags. It is also possible to fill a vinyl sheet or a nonwoven sheet with culture soil and place it in the container set gap 10 as the cultivation container 24.
(Horizontal rod 4b)

As shown in FIG. 6, the horizontal rod 4b has a stepped shape and includes a horizontal portion 4c located on the underside of the net material 1, and a mounting portion 4e located below the horizontal portion 4c and supporting the cultivation container 24 placed in the container set gap 10. As shown in the figure, the horizontal portion 4c and the mounting portion 4e are connected via a stepped bend portion 4d, and the horizontal portion 4c, the mounting portion 4e, and the stepped bend portion 4d are composed of a single metal pipe 8. Both ends of the mounting portion 4e and the horizontal portion 4c are each connected to the vertical leg portion 5a of the support leg 5, and the mounting portion 4e supports the cultivation container 24 placed in the container set gap 10, and the horizontal portion 4c supports the net material 1.

By setting the length of the horizontal rod 4b to a predetermined length that matches the width of the lateral side of the stand 30, length adjustment is not required, and assembly and installation can be easily performed. In addition, the horizontal rod 4b has a horizontal portion 4c, a mounting portion 4e, and a step bend portion 4d, and is composed of one metal pipe 8. The step bend portion 4d is formed by bending the metal pipe 8, so positioning and fine adjustment of the height difference during assembly is not required, and assembly and installation can be easily performed. Furthermore, there is no need to join three members of different lengths, the horizontal portion 4c, the mounting portion 4e, and the step bend portion 4d therebetween, with joints, which reduces the number of parts and reduces costs.
(Bottom support bar 4f)

As shown in Figures 5 and 6, the bottom support bar 4f is connected to the mounting parts 4e of the horizontal rods 4b in a crossed position, so that the cultivation containers 24 to be placed in the container set gap 10 can be loaded. As shown in Figure 6, the bottom support bar 4f is connected to the top of the mounting parts 4e, so that the cultivation containers 24 installed in the longitudinal direction of the container set gap can be directly supported from below. As with the vertical rods 4a, the bottom support bar 4f can use a U-shaped member 20 having bent parts on both sides of the flat surface extending in the longitudinal direction. The U-shaped member 20 is light and strong, and can be used in common with the vertical rods 4a. As shown in Figure 6, the cultivation containers 24 to be placed in the container set gap 10 can be stably supported by placing the flat surface of the U-shaped member 20 as the upper surface. By passing two U-shaped members 20 through the container set gap, the cultivation containers 24 can be stably supported while maintaining their horizontal position. In addition, the flat surface of the U-shaped member 20 can be used to easily secure the bottom support bar 4f and the mounting portion 4e. It can be secured from above the bottom support bar 4f, making positioning and assembly easy. The bottom support bar 4f is connected to the mounting portion 4e, and the vertical rod 4a is separately connected to the horizontal portion 4c, ensuring the strength of the entire stand 30 and enabling stable support.

By setting the cultivation container 24 on the lower mounting portion 4e formed in the container set gap 10, the cultivation container 24 can be placed at a position lower than the net material 1, and the center of gravity of the entire stand 30 is lowered, which contributes to stable support of the entire stand 30. In addition, by providing the container set gap 10 and placing the cultivation container 24, the cultivation container 24 can be stably supported. In particular, the cultivation container 24 is supported on the outer side by the vertical pipe 2a, the inner side by the side edge of the net material 1, sandwiched between guides that support it from both sides, and the lower part is supported by the bottom support bar 4f, so that the cultivation container 24 fits well and is prevented from falling or tipping over. Therefore, even if some kind of impact is inadvertently applied to the stand 30 during work, the cultivation container 24 can be prevented from falling or tipping over. The good fit of the cultivation container 24 means that the heavy cultivation container 24 containing the soil can be easily installed in the container set gap 10, and work can be done safely. In addition to containers with flat bottoms, such as plastic planters, containers that lack stability, such as plastic pots and bags, can be used. A net or sheet can be placed between the vertical pipe 2a and the side edge of the expanded metal 1a. A fastener that fits along the outer diameter of the metal pipe 8 can also be used on the vertical pipe 2a side.

The above structure is suitable for cultivating plants that grow baby plants 22b by extending runners 23 from a parent plant 21a. For example, it can provide a suitable growing environment for cultivating strawberries, and facilitate cultivation management. Figure 7 is a vertical cross-sectional view showing an example of use of the stand 30 shown in Figure 5. As shown in Figure 7, a step is provided in the cultivation area, and the upper surface of the net material 1 is the cultivation area for the baby plants 21a, and the container set gap 10 can be the cultivation area for the parent plant 21a in which the parent plant container 21 for cultivating the parent plant 21a is placed.

By placing the parent plant 21a in the container set gap 10 on the lower stage mounting portion 4e, the runner 23 from the parent plant 21a can grow horizontally (horizontal cultivation). The runner 23 is also called a stolon, and grows by creeping along the ground, and when it sprouts and lands, another child plant 22a is produced from it, and this process is repeated. Not only the parent plant 21a but also the child plant 22a can produce multiple runners 23, and in the case of strawberries, one parent plant 21a can be divided into about 10 to 30 plants. The runner 23 from the parent plant 21a is a vine that supplies nutrients to many child plants 22a, and acts as an "umbilical cord." Since it affects the growth of the child plants 22a, it is important to keep the growth of the parent plant 21a and the runner 23 in good condition without stress. Horizontal cultivation can avoid the problem of vertical cultivation, which causes the runner 23 to droop. The runners 23 can grow without stress from moisture, sunlight, etc., and by guiding the runners 23 onto the net material 1, it is easy to manage the cultivation so that the runners 23 do not get tangled. Strict water management is also not necessary. The runners 23 can be prevented from touching or rubbing against the edge of the planter of the parent plant container 21, and from physical damage caused by heat, etc. There is no need to place the parent plant container at a high position such as 2 m as in vertical cultivation, and the strawberry parent plants, which are sensitive to heat, are not exposed to harsh environments, and measures such as air conditioning and sunlight are not required.

By making the top surface of the net material 1 the cultivation area for the seedlings 22a, as shown in FIG. 7, when the runner 23 is guided toward the net material 1, the parent seedlings 21a can be managed in the container set gap 10, and the seedlings 22a can be managed on the net material 1. Therefore, the parent seedlings can be mainly managed from the container set gap 10 side of the stand 1, and the seedlings 22a can be mainly managed from the opposite side of the net material 1, making it easy to work. On the top surface of the net material 1, which is the cultivation area for the seedlings 22a, the seedling containers 21 can be freely arranged and moved, making cultivation management easy. By positioning the cultivation area for the parent seedlings 21a on the lower level, the height of the parent seedlings 21a and the parent seed container 21 does not get in the way of work, and the condition of the plant can be easily observed and cultivation management can be easily performed even from the parent seed container 21 side of the stand 30.

The width (W2) of the net material 1 is secured to be wide enough to carry multiple seedling containers in the width direction, so that the growth of the runners 23 extending horizontally is not hindered, and they can grow like creeping stems along the ground. Furthermore, the width (W2) of the net material 1 can be made wider than the width (W1) of the container set gap 10, so there is more space for cultivating the seedlings 22a. In the case of strawberries, one parent plant 21a can be divided into about 10 to 30 plants, so it is important that there is more space for the runners 23 to extend horizontally in horizontal cultivation. Since the seedlings 22a can be cultivated on the net material 1, containers such as polypots, trays, and planters can be used without limiting the type, size, and shape of the seedling containers 22. Culture soil can also be laid directly on a vinyl sheet, a nonwoven sheet, etc. A variety of cultivation methods can be accommodated. The placement location of the seedling container 22 can be freely decided and can also be moved, creating even more space. For example, the runners 23 and seedlings 22a can be placed in a seedling container 22 such as a polypot while observing their growth status, and can be placed and moved to a location of your choice. Cultivation management is easy and work is also easy, as the runners can be spaced apart to ensure sufficient sunlight so that they do not get tangled, placed in a location suitable for watering, and moved as necessary. This gives users more freedom in their cultivation methods.

7 is set to, for example, about 90 cm to 100 cm, preferably in accordance with the standard size of the expanded metal 1a. However, the width can be adjusted by cutting and adding to the expanded metal 1a.
[Embodiment 3]

Fig. 8 is a schematic perspective view showing a mount 300 to which a pitching prevention pipe 16 according to the third embodiment is connected. As shown in Fig. 8, the mount 300 includes a pitching prevention pipe 16 connected to the support leg 5 and the loading rod 4. By providing the pitching prevention pipe 16, the strength of the mount 300 as a whole can be ensured, enabling stable support, particularly against longitudinal vibration of the mount 300 that has reached a certain length or more. A pair of pitching prevention pipes 16 are installed side by side on both sides of the mount 300 in the longitudinal direction, allowing the mount 300 to be supported in a well-balanced manner.
(Pitching prevention pipe 16)

As shown in Figure 8, the pitch-prevention pipe 16 has a horizontal pipe section 16a extending in the longitudinal direction of the net material 1, and a brace section 16b connected to the horizontal pipe section 16a via an acute-angled bend section 16c. The tip of the horizontal pipe section 16a is connected to the horizontal leg section 5b of the support leg 5, and the tip of the brace section 16b is connected to the horizontal rod 4b. Although not shown, the tip of the horizontal pipe section 16a can be connected to the lower end or bend section 5c of the vertical leg section 5 of the support leg 5a, and the tip of the brace section 16b can also be connected to the vertical rod 4a.

In general, a brace is a reinforcing member that increases the strength of a structure, and is a member that reinforces a structure by inserting it diagonally between columns and connecting them. For example, a brace is placed diagonally on the square formed by the columns and beams to create a triangular structure and prevent deformation. As shown in Figure 8, the tip of the brace part 16b of the pitching prevention pipe 16 is connected to the horizontal rod 4b, and the tip of the horizontal pipe part 16a is connected to the horizontal leg part 5b. Therefore, although reinforcing material is not added to the diagonal of the square, when the tip of the brace part 16b of the pitching prevention pipe 16 is connected to the horizontal rod 4b and the tip of the horizontal pipe part 16a is connected to the horizontal leg part 5b, when the platform 300 is viewed from the side (when the longitudinal direction of the platform 300 is viewed from the side), a roughly triangular structure is created and reinforced, so it is called the brace part 16b.

Although not shown, it is also possible to provide a through hole in the horizontal pipe section 16a and drive a pin or the like through the through hole into the ground to fix it to the installation surface. This can further improve the stable support of the stand 300. Also, it is possible to fix the horizontal leg section to the ground with a U-shaped pin or the like without providing a through hole.
(Inner support leg 5B)

As shown in FIG. 8, the pitching prevention pipe 16 is preferably connected to the inner support leg 5B located on the inside of the end support leg 5A located at the end of the longitudinal direction of the frame 300. Compared to when the pitching prevention pipe 16 is connected to the end support leg 5A located at the end of the longitudinal direction of the frame 300, the pitching prevention pipe 16 can support the inside more, and the part of the frame 300 outside the inner support leg 5B becomes a weight with strength in the longitudinal direction, so that the overall balance of the frame 300 can be maintained. The effect of the pitching prevention pipe 16, which ensures the strength of the entire frame 300 against the longitudinal shaking of the frame 300 and provides stable support, can be more effectively exerted. Depending on the longitudinal length of the frame 300, a pitching prevention pipe 16 can also be added between the inner support leg 5B and the inner support leg 5B. By connecting the pitching prevention pipe 16 to the inner support leg 5B, the number of pitching prevention pipes 16 can be reduced, and weight and cost can be reduced.
(Fourth connector 14, fifth connector 15)

As shown in FIG. 9, a connector that connects the pitch-stop pipe 16 to the base 300 body may be provided. Either or both of a fourth connector 14 that connects the end of the brace 16b to the horizontal rod 4b and a fifth connector 15 that connects the end of the horizontal pipe 16a to the lower part of the support leg 5 may be provided. As shown in FIG. 9, for example, the fourth connector 14 may have a fourth U-shaped bend 14a formed by bending in a U shape along the surface of the horizontal rod 4b, and a fourth connecting piece 14b that is connected to both ends of the fourth U-shaped bend 14a and connected to the end of the brace 16b. The fourth U-shaped bend 14a and the fourth connecting piece 14b are made of a single metal plate, and the fourth U-shaped bend 14a is connected to the horizontal rod 4b, and the fourth connecting piece 14b is connected to the end of the brace 16b. Similarly, for example, the fifth connector 15 may have a fifth U-shaped bent portion 15a formed by bending in a U-shape along the surface of the lower portion of the support leg 5, and a fifth connecting piece 15b connected to both ends of the fifth U-shaped bent portion 15a and connected to the end of the horizontal pipe portion 16a. The fifth U-shaped bent portion 15a and the fifth connecting piece 15b are made of a single metal plate, and the fifth U-shaped bent portion 15a is connected to the lower portion of the support leg 5, the fifth connecting piece 15b is connected to the end of the horizontal pipe portion 16a, and the fifth connecting piece 15b is connected to the lower portion of the support leg 5. As shown in FIG. 9, the fifth U-shaped bent portion 15a is preferably connected to the horizontal leg portion 5b of the support leg 5, but it may also be connected to the lower portion of the vertical leg portion 5a or the bent portion 5c.

The fourth connector 14 and the fifth connector 15 can be fixed by various methods such as simply screwing, pinning, locking parts, and fasteners (belts), and the method is not limited. By using the fourth connector 14 and the fifth connector 15, the anti-pitch pipe 16 can be easily connected and fixed, making assembly easy and leading to low costs. When using metal pipes 8 of the same diameter and thickness, a common connector can be used for the first connector 11, the second connector 12, the fourth connector 14, and the fifth connector 15. Components can be standardized, resulting in low costs.

The elevated cultivation rack of the present invention is particularly suitable for raising seedlings of plants that grow by runners, such as strawberries.
