Description

[Technical Field]

[0001] The present invention relates to a leek cultivation device suitable for cultivating leek. [Background technology]

[0002] Plastic planters have traditionally been used for home vegetable gardens on the balconies of apartments and condominiums. Because planters are shallow, they are used to grow fruit vegetables, leafy vegetables, herbs, etc.

[0003] However, ordinary planters are too shallow to cultivate root vegetables such as radishes and carrots. Furthermore, it is not possible to hill up vegetables such as leeks and Chinese yams, which require hilling up of soil.

[0004] For example, the vegetable cultivation container in Patent Document 1 has an expandable accordion structure that allows it to be folded up thinly like a lantern when not in use or when stored, and when in use it can be expanded and adjusted to any height depending on the type of vegetables being cultivated.

[0005] [Patent Document 1] Registered Utility Model No. 3048353 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the conventional vegetable cultivation container in Patent Document 1 could only change its height according to the amount of expansion and contraction of the bellows. Therefore, when cultivating green onions, there was a problem that the height was insufficient and it was difficult to increase the height during cultivation.

[0007] Therefore, an object of the present invention is to provide a leek cultivation device that does not become short of height and that can easily increase height even during cultivation. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the leek cultivation device of the present invention is a leek cultivation device used for cultivating leek, and is equipped with a multi-tube section formed in a nested manner by multiple tubes so that the height can be changed according to the growth of the leek, and a locking section attached to the multi-tube section and for locking to a surrounding fixed object. [Effects of the Invention]

[0009] In this way, the leek cultivation device of the present invention comprises a multi-tube portion formed in a nested manner by multiple tubes, and a locking portion attached to the multi-tube portion for locking to a surrounding fixed object, so that the leek cultivation device does not lack the height required for the leek and can easily increase the height even during cultivation.

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the components described in the following examples are merely examples and are not intended to limit the technical scope of the present invention. [Example]

[0012] (composition) First, the overall configuration of the leek cultivation device 1 of the present invention will be described using Figures 1 and 2. As shown in Figures 1 and 2, the leek cultivation device 1 comprises a multi-tube section 2 formed in a nested manner by multiple tubes 21, 22, ..., 27, a locking section 3 attached to the upper part of the multi-tube section 2, and a receiving tray section 4 attached to the lower part of the multi-tube section 2.

[0013] The multi-tube section 2 is formed in a nested (handle-like) shape by combining, for example, seven tubes 21, 22, ..., 27 of different diameters, and is thereby configured to be extendable. That is, the length can be extended by sliding in order from the uppermost tube 21 with the largest diameter to the lowermost tube 27 with the smallest diameter.

[0014] For example, tube 22 is cylindrical and made of synthetic resin, and has main body 22a, flange 22b at the upper end of main body 22a with its outer edge bulging outward, and annular protrusion 22c at the lower end with its inner edge bulging inward. The other tubes 21, 23 to 27 have substantially the same configuration except for their different diameters and lengths. Therefore, flange 23b of tube 23 is adapted to be caught on annular protrusion 22c of tube 22.

[0015] The uppermost cylinder 21 is fitted with a locking portion 3. The lowermost cylinder 27 is fitted with a receiving tray 4. The configurations of the locking portion 3 and the receiving tray 4 will be described later.

[0016] Furthermore, a filter 5 is disposed inside the lowest cylinder 27 so as to close the bottom at the lower part. The filter 5 may be made of, for example, a nonwoven fabric, but is not limited to this and may also be made of a mesh.

[0017] The locking portion 3 is attached to the multi-tube portion 2 and is used to lock the entire leek cultivation device 1 to a fixed object in the vicinity. Specifically, the locking portion 3 is a loop-shaped belt that is looped around and fastened to a handrail or the like on a balcony of an apartment building. Note that the locking portion 3 is not limited to a loop-shaped belt, and may be anything that can be locked or fastened to a fixed object in the vicinity, such as a hook-shaped hook, or may be fastened to a wall with a rivet or screw.

[0018] The tray 4 is composed of a main body 40, which is a shallow dish or container placed below the lowest tube 27, and a string (rope) 41 for suspending the main body 40 from the tube 27. Therefore, it catches water dripping from the lowest tube 27 and prevents it from soiling the balcony. Furthermore, the tray 4 can be easily removed from the tube 27 so that accumulated water can be discarded and the inside can be cleaned.

[0019] The leek cultivation device 1 of this embodiment further includes height restriction means 6 that restricts the height of the multi-tube section 2 in accordance with the growth of the leek. The height restriction means 6 determines the length of the multi-tube section 2 in the sliding direction, and can also be called a "height regulation means" or "height adjustment means." In other words, the provision of the height restriction means 6 prevents the multi-tube section 2 from becoming too long due to the weight of each tube 21-27 or the soil inside. The height restriction means 6 can be, for example, a string (rope) stretched between the uppermost tube 21 and the lowermost tube 27.

[0020] (action) Next, the operation of the leek cultivation device 1 of this embodiment will be described with reference to Figures 3 and 4. Here, the initial state and final state will be described as examples.

[0021] First, the initial state will be described with reference to Figure 3. The initial state is the state immediately after the leek seedlings have been planted. In this state, the second tube 22 has slid relative to the first, top tube 21, and the remaining tubes 23 to 27 are folded. Note that with such a low height, the container can be placed on a flat surface without using the locking portion 3. Even in this case, it is preferable to use the tray portion 4.

[0022] Next, the final state will be explained using Figure 4. The final state is the state when the leeks have grown and are just about to be harvested. In this state, the second tube 22 has slid relative to the first, top tube 21, and the remaining tubes 23 to 27 also slide and extend in order. When the height is increased like this, it is preferable to hang the leek cultivation device 1 on a fixed object such as a balcony railing using the locking part 3. In this case, the tray part 4 is suspended by a string 41.

[0023] (effect) Next, the effects achieved by the leek cultivation device 1 of this embodiment will be listed and explained.

[0024] (1) As described above, the leek cultivation device 1 used in this embodiment for cultivating leeks includes a multi-tube section 2 formed of multiple tubes 21-27 nested together, allowing the height to be adjusted according to the growth of the leeks, and a locking section 3 attached to the top tube 21 of the multi-tube section 2 and locked to a surrounding fixture. This configuration ensures that the leek cultivation device 1 does not become insufficient in height and can easily increase its height even during cultivation. In particular, the "soil piling" required for cultivating leeks can be easily performed. Specifically, soil is poured in through the top opening of the first tube 21. Thus, soil piling, which is impossible with a conventional planter, can be achieved with a simple configuration.

[0025] In addition to leeks, the leek cultivation device 1 can also be used to cultivate plants that grow vertically (deeply) underground, such as burdock. Furthermore, it is more preferable to apply it to plants that require hilling up of soil during cultivation.

[0026] (2) In addition, the multiple cylinder section 2 is further equipped with a receiving tray section 4 that is positioned below the lowest cylinder 27 to receive drainage water, so that the drainage water can be received without soiling the balcony.

[0027] (3) Furthermore, by providing a string as a height control means 6 that controls the height of the multi-tube portion 2 in accordance with the growth of the leeks, the multi-tube portion 2 can be prevented (controlled) from extending more than necessary due to its own weight and the weight of the soil inside.

[0028] (4) Furthermore, the filter 5 is installed in the lowest tube 27 of the multi-tube section 2 so as to close the bottom, thereby preventing soil from flowing out from within the multi-tube section 2.

[0029] Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes that do not deviate from the gist of the present invention are included in the present invention.

[0030] For example, in the embodiment, the leek cultivation device 1 has been described as having the length restriction means 6, but this is not limited to this, and if there is a frictional force between the tubes 21 to 27 that is within the sliding range due to the weight of the soil alone, the length restriction means 6 is not necessary. Alternatively, the length restriction means 6 may be a rubber band.

[0031] In addition, in the embodiment, a case where a string is used as the length control means 6 is described, but this is not limited to this, and it is also possible to configure the lowest tube 27 to always be in contact with the ground by sequentially adjusting the length of the belt that is the locking portion 3 according to the length of the multiple tube portion 2.
