Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a plant attracting tool used when cultivating plants such as cucumbers, tomatoes, and melons in greenhouses.

[Conventional technology]

When growing plants, supports were used to support the plants, but instead of this, so-called induced cultivation involves hanging strings from wires stretched inside the plant cultivation house and tying the stems of the plants to them. It has become widely used. This has the advantage that it is cheaper than using conventional supports because it only uses wire and string, and it is easier to dispose of after cultivation.

However, the following problems also occurred in induced cultivation.

[Problem that the invention attempts to solve]

That is, the work of tying a string suspended from a wire to a plant stem is extremely troublesome. As the plant grows and the stem lengthens, the position of the attracting string is shifted along the wire, and the supporting position of the stem is changed so that the base side of the stem creeps over the ridge, so that the plant is too tall. We must make sure that this does not happen.

As the plant grows, it is time-consuming to untie the string that binds the stem and tie it tightly again, and even if you use a simple hook to secure it, it will come off, and once the plant has fruit, the hook will no longer be able to support it. There was a problem.

This idea was created in view of the above problems.
To provide an attracting tool which does not have to worry about the stem coming off and can easily change the supporting position of the stem any number of times.

[Means to solve the problem]

In order to achieve the above object, the attracting device of the present invention has the following configuration, that is, it is equipped with a spring column, and an annular portion is formed at one end of a substantially V-shaped wire body, and an annular portion is formed at one end of a substantially V-shaped wire body. The end is provided with a hook portion that can be inserted into and taken out from the annular portion.

[Effect]

According to the configuration of the present invention, since the almost inverted V-shaped wire body has spring properties, the annular part and the hook part provided at each end of the wire body can be connected with two fingers. Even if the distance between the two is compressed, the structure is such that it will return to its original state once the force is removed. Therefore, for example, by compressing the respective wire bodies of the annular part and the hook part with the thumb and forefinger, the curved tip of the hook part passes through the annular part, and then the both ends are pushed until a gap between the tip and the annular part opens. After compressing it with your fingers and inserting the plant stem into the hook through the gap, when you release the pressure from your fingers, the hook will try to return to its original direction due to the repulsive force of the spring of the wire body. , the plant stem is tightly held between the hook and the ring. If you want to remove it, just do the reverse operation and it will come off easily. However, once the stem is clamped, it will not easily come off or come off unless the annular part and the hook part are compressed by human force. Furthermore, the plant attracting device of the present invention can freely change the clamping force depending on the strength of the spring force.

As described above, according to the configuration of the present invention, the position of supporting the plant stem can be freely changed with an extremely simple operation.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of the present invention, in which 1 is a plant attractor, 2 is an annular portion, and 3 is a hook portion.

The annular portion 2 is an elliptical annular body formed at the end of an annular support portion 12 made of a wire so that a surface formed by the wire forming a ring faces in the vertical direction. The hook part 3 is provided at the end of a hook support part 13 made of a wire body, and the tip of the hook support part 13 is bent at a substantially right angle toward the annular part 2.
Furthermore, the tip is bent horizontally and a curved portion is formed there. 4 is a string for hanging the attracting device 1. The hook portion 3, the hook support portion 13, the annular portion 2, and the annular support portion 12 can all be formed by bending a single metal wire. As the metal wire, any wire having spring properties such as iron wire, steel wire, aluminum wire, etc. can be used.
In addition to metal wires, it is also possible to use synthetic resins such as polyethylene, polypropylene, and polyvinyl chloride molded by injection molding or the like.

When using steel wire among the above metal wires,
It is necessary to prevent rust by applying plating or synthetic resin coating to the entire structure. In addition, an annular portion 2 that supports plants
It is desirable that the hook portion 3 is partially covered with soft resin so as not to damage the stem of the plant.

FIG. 2 is a plan view taken along the line X-Y in FIG. 1, showing the positional relationship between the annular portion 2 and the hook portion 3. FIG. According to FIG. 2, in the annular portion 2, the width A of the ring formed by the wire must be sufficiently larger than the width a of the hook portion 3 formed by the other wire. There is. Furthermore, when the hook part 3 is inserted into the annular part 2 as shown by the broken line in FIG.
There must be a sufficient distance between the tip 33 of the curved wire body and the annular portion 2 to allow the stem of the plant to pass through. Although the thickness of the wire varies depending on the material, a steel wire of 1.0 to 2.5 mm is preferably used. In addition, the size of the attracting device can be set to a suitable size depending on the plant, but for tomatoes and cucumbers, the distance from the top where the string is tied to the bottom of the ring part 2 is about 10 to 20 cm, preferably about 12 to 16 cm. It is easy to use, easy to process, and economical.

FIG. 3 is a perspective view showing a state in which the attracting device of the present invention shown in FIG. 2 holds a plant stem. Third
To explain the method of attracting plants based on the diagram, both supporting parts 1 of the attracting device 1 suspended from a string
2 and 13 with one hand, insert the hook part 3 into the annular part 2, and hold the plant stem 7 from the gap between the tip of the hook part 3 and the annular part 2 with the other hand. When the hook part 3 is inserted into the curved part and the force holding the support parts 12 and 13 is loosened, the spring force of the support parts 12 and 13 moves the hook part 3 in the direction of coming out of the annular part 2.
Due to the presence of the plant stem 7, the hooked portion 3 accumulates within the annular portion, and the stem 7 remains held between the hooked portion 3. Since the stem of a plant is generally oriented vertically, the hook part 3 is formed with a horizontal curved part that serves as a hook to make it easier to receive the stem.
The direction of the hook portion 3 is not necessarily limited. The hook part 3 is not particularly limited as long as it wraps around the stem of the plant, faces the direction of the annular part 2, and can be inserted into and taken out from the annular part.

Further, the shape of the annular portion may be a horizontally long annular shape as shown in FIGS. 1 and 3, or may be circular or square, as long as the hook can be freely inserted and extracted. good. Furthermore, the annular part does not have to be completely ring-shaped, and even if it is partially or half missing, as long as the stem of the plant can be held between the hook part and the annular part, this invention is applicable. This does not deviate from the technical philosophy of

FIGS. 4 and 5 are perspective views showing other embodiments of the attracting device of the present invention, in which the annular portion is deformed.

FIG. 6 is a schematic view showing how the attracting device of the present invention is used, and 10 is a tension wire stretched inside an agricultural or horticultural greenhouse or the like. The stem 7 of the plant is held by the attracting tool of the present invention and moved slightly in the direction of the arrow X in FIG. 6 to adjust the degree of support of the plant. Plants grow upwards, but the roots that do not bear fruit and the parts that have already set fruit are placed along the ridges, and the part that does bear fruit is moved to a suitable position for cultivation. In order to do this, the string 4 on which the attracting device 1 is suspended is successively moved in the direction of the arrow X. In addition, the supporting position is appropriately changed each time it is moved.

[Effect of idea]

In this invention, a wire body with spring properties is formed into a substantially inverted V shape, and an annular part and a hook part are provided at the ends of the wire body. The stem can be easily clamped, and once the stem is clamped, it will not come off from the attracting tool. Therefore, it is possible to greatly reduce the effort and time required to move the attracting tool and change the supporting position of the stem as the plant grows, and is extremely effective in contributing to labor saving in agricultural work.

In addition, the attracting device of the present invention is composed of a wire body, and in addition to the economical merits of the material, it is easy to form, and in the case of metal wires, it can last for a long time as long as the wire material is subjected to anti-corrosion treatment. It has the advantage that it can be used without worrying about damage.
