Description

The present invention relates to an attractant that attracts stems and fruit clusters of tomatoes and the like.

The stems of plants such as tomatoes, eggplants, cucumbers, melons and peppers grow upward as they grow. In the past, a string hung from above was tied to the root of the plant, and the stem of the plant was wrapped around the tied string to attract the plants. It takes a lot of time and effort to hang and move. At this time, depending on how the fruit bunch is enlarged, the impact at the time of hanging or the weight of the fruit bunch may cause the fruit bunch shaft to break or tear.

Fruits tend to grow in the growth condition of tomatoes, especially in the fruit clusters that have set in the early stage of planting. The weight of the enlarged fruit may cause a break 40 of the fruit bunch shaft 31 of the fruit bunch 30 as shown in FIG. 9, and as a result, the proper growth of the fruit is hindered. In some cases, the fruit bunch shaft 31 may tear from the root as shown in FIG. When the tear 41 occurs, the fruit bunch 30 itself often falls.

Therefore, as shown in FIG. 11, the fruit bunch 30 is hung by a string 42, or as shown in FIG. 12, a hook 43 made of a wire is used to hang it. However, when the fruit bunch 30 is hung by the string 42, it takes time and effort to cut and prepare the string 42 and to tie the string 42, which is difficult. Further, when the tied string 42 is removed, it takes time to cut the string 42. Therefore, after harvesting the fruit of the fruit bunch 30, the string 42 is cultivated without being collected, and the fruit is collected after the cultivation is completed. At this time, since it is difficult to confirm the string 42, forgetting to collect it occurs. Depending on the type of the string 42, if it is mixed with the residue after harvesting, it may remain in the soil later.

Further, when the hook 43 made of wire is used, it takes time and effort to cut the wire and bend it by hand every season. Further, if the hooks 43 are collected and stored after harvesting, the hooks 43 are entangled with each other and deformed when they are taken out in the next season, and eventually, the hooks 43 must be newly remade every season. In addition, since rust is also generated, it can only be used in one season from the viewpoint of disease prevention. In addition, the cut surface is sharp and can cause injury or damage to crops during work.

Further, as shown in FIG. 13 (A), an arch-shaped product 44 attached to the fruit bunch shaft is known. In this product 44, when attaching to the fruit bunch 30, it is necessary to bend and stretch the product 44 as shown in FIGS. (B) and (C) at an early stage, and then attach the product 44 as shown in FIG. (D). Therefore, it takes time and effort. Further, at the time of early mounting, it is necessary to disperse the flowers of the fruit bunch 30 and insert the fruit bunch shaft 31 which is thin and easily broken because it is early, so as not to damage or damage it, which takes a lot of time and effort. Further, in this product 44, even if it is carefully attached as described above, the bending of the fruit bunch shaft 31 can be reduced, but as shown in FIG. 14, there is no effect on the tear 45 of the fruit bunch shaft 31. ..

Further, as shown in FIG. 15, there is known a fruit bunch hanging tool 47 that is attached to an attracting string 46 to lift a fruit bunch 30. However, this fruit bunch hanging tool 47 cannot be attached without the attracting string 46. In addition, in the attraction method of hanging from string to string using a clip, etc., or the attraction method of shifting the stem from the attract string and lowering it, the fruit bunch hanging tool is also removed, the stem is lowered, and then it is moved again. If it is not attached, the fruit cluster will break or the fruit will fall. In this case, damage to the fruit cluster may occur during installation and removal, which requires a lot of labor.

Further, for example, as described in Patent Document 1, a plurality of upper hooking portions formed in a state of having different heights in the upper and lower portions, and a plurality of lower hooking portions formed in a state of having different heights in the upper and lower portions. A fixed support for a branch of an agricultural product is known in which an upper hook portion and a lower hook portion are rotatably meshed with each other and fastened to each other. In this fixing support, by appropriately selecting from a plurality of upper hooks and a plurality of lower hooks, the span of the interval corresponding to the distance between the upper branch and the lower branch of the crop can be set. These branches can be fixed to each other.

Japanese Patent No. 5934740

However, the fixed support described in Patent Document 1 has a complicated structure and is expensive because the upper hook portion and the lower hook portion can rotate freely with each other. Further, although the upper hook portion and the lower hook portion can rotate freely with each other, it may not be possible to handle them properly when attaching or detaching only by this rotation. In addition, since it rotates freely, it may rotate during the growth of the stem, and the stem may come off from the upper hook portion and the lower hook portion.

Therefore, it is an object of the present invention to provide an attractant that is easy to attach and detach and does not easily come off even when the stem or fruit bunch grows.

The attractor of the present invention has flexibility and elasticity, and has a first shaft portion extending in the first direction and a substantially J-shaped first hook extending from the base end portion of the first shaft portion in the first direction. A portion, a substantially J-shaped second hook portion extending from the tip portion of the first shaft portion in the first direction, and a second shaft portion extending from the tip portion of the first shaft portion in the first direction. It has a substantially J-shaped third hook portion extending in the opposite direction to the second hook portion centering on the second shaft portion from the tip end portion of the second shaft portion.

In the attractor of the present invention, the first hook portion is hooked at an appropriate position on the fruit bunch shaft, and the second hook portion or the third hook portion is attached to the upper stem or branch by twisting the first shaft portion having flexibility and elasticity. Select one of the hooks and hook it. As a result, the first hook portion and the second hook portion or the third hook portion are brought together with the fruit bunch shaft by the force (elastic force) generated by twisting the first shaft portion to return to the original position of the first shaft portion. It is fixed to the stems and branches, and it becomes difficult to come off due to the growth of the stems and fruit clusters.

It is desirable that the second shaft portion also has flexibility and elasticity. As a result, as described above, the second shaft portion is twisted in addition to the first shaft portion, and the first hook portion and the second hook portion are also twisted by the force (elastic force) that tries to return to the original of the second shaft portion. The hook portion or the third hook portion is fixed to the fruit bunch shaft and the stem or branch, and is difficult to come off due to the growth of the stem or fruit bunch.

It is desirable that the attracting tool of the present invention has a protrusion portion protruding inward in a substantially J shape at the tip end portion of the first hook portion. As a result, even if the fruit bunch shaft hooked on the first hook portion tries to come off from the first hook portion, it will be blocked by the protrusion portion, and will not easily come off due to the growth of the stem or fruit bunch.

In the attracting tool of the present invention, the center of the curve of the first hook portion is on the extension of the central axis of the first shaft portion, and the second hook portion is on the same side as the first hook portion with respect to the first shaft portion. It is desirable that the second shaft portion is offset from the first shaft portion toward the second hook portion. As a result, the center of the curve of the second hook portion on the same side as the first hook portion with respect to the first shaft portion and the opposite of the second hook portion centering on the second shaft portion from the tip portion of the second shaft portion. The center of the curve of the third hook portion extending in the direction is arranged at a position close to the central axis of the first shaft portion, and either the second hook portion or the third hook portion is selected. Also, the force applied to the 1st shaft by the fruit bunch axis held by the 1st hook, which has the center of curvature on the extension of the central axis of the 1st shaft, is placed near the central axis of the 1st shaft. It can be supported by a second hook portion or a third hook portion in.

(1) Hook the first hook part at an appropriate position on the fruit bunch shaft, and twist the flexible and elastic first shaft part to attach either the second hook part or the third hook part to the upper stem or branch. It can be attached by simply selecting and hooking it, and it is also easy to remove.

(2) Further, the first hook portion and the second hook portion or the third hook portion are formed by a force (elastic force) generated by twisting the first shaft portion to return to the original position of the first shaft portion. It is fixed to the stem and stems and branches, and it is difficult to come off due to the growth of the stem and fruit cluster. In addition, the flexibility of the first axis has extremely small effect on the fruit cluster, fruit cluster shaft, stem and branch, and the plant It is possible to attract with less influence on growth.

The size is 0.5 to 1.5 mm (1.0 mm in the example of this embodiment). Similarly, the width of the second direction Y is 2.0 to 4.0 mm (3.0 mm in the example of the present embodiment) and the third direction Z so that the second shaft portion 12 also has appropriate flexibility and elasticity. The thickness is 0.5 to 1.5 mm (1.0 mm in the example of this embodiment).

The width and thickness of the first hook portion 21, the second hook portion 22, and the third hook portion 23 are 2.0 to 4.0 mm (3.0 mm in the example of the present embodiment), and the first shaft portion 11 and the first shaft portion 11 and the first hook portion 23 are set to 3.0 mm. It is less likely to be elastically deformed than the biaxial portion 12. Further, on the outside of the second hook portion 22, a reinforcing rib 13 is provided so as to connect the first shaft portion 11 and the second shaft portion 12. The thickness of the reinforcing rib 13 in the third direction Z is the same as the thickness of the first shaft portion 11 and the second shaft portion 12. Further, a reinforcing rib 14 extends from the second shaft portion 12 to the outside of the third hook portion 23. The thickness of the reinforcing rib 14 in the third direction Z is the same as the thickness of the second shaft portion 12.

The first hook portion 21 extends diagonally in the Y direction from the base end portion 11A of the first shaft portion 11 and is curved in a substantially J shape centered on the extension of the central axis of the first shaft portion 11. .. The radius of curvature R1 of the inner bottom portion 21A of the first hook portion 21 is 3.5 mm in this embodiment. Further, the tip portion of the first hook portion 21 has a protrusion 24 protruding inward in a substantially J shape.

The second hook portion 22 has a shape curved from the tip end portion 11B of the first shaft portion 11 to the same side as the first hook portion 21 with respect to the first shaft portion 11 in a substantially J shape. The radius of curvature R2 of the inner bottom portion 22A of the second hook portion 22 is larger than the radius of curvature R1 of the first hook portion 21. In this embodiment, the radius of curvature R2 is 10 mm.

The second shaft portion 12 extends from the middle of the second hook portion 22 of the tip end portion 11B of the first direction X of the first shaft portion 11 to the first direction X. That is, the second shaft portion 12 is at a position offset from the first shaft portion 11 toward the second hook portion 22. In the present embodiment, the second shaft portion 12 is set at a position offset by 5.0 mm from the first shaft portion 11.

The radius of curvature R3 of the inner bottom portion 23A of the third hook portion 23 is larger than the radius of curvature R1 of the first hook portion 21. In the present embodiment, the radius of curvature R3 is 10 mm, which is the same as the radius of curvature R2.

Next, a method of attracting tomatoes and the like using the attracting tool 1 having the above configuration will be described with reference to FIGS. 3 to 8.

Since the attractor 1 in the present embodiment has at least the first shaft portion 11 having flexibility and elasticity, it can be attached to the fruit cluster of a crop such as tomato at an early stage. As shown in FIG. 3, the attractor 1 hooks the first hook portion 21 to an appropriate position of the fruit bunch shaft 31 of the fruit bunch 30 and twists the first shaft portion 11 from the back of the stem 32 to the upper part of the fruit bunch. The third hook portion 23 is hung on the branch 33B.

At this time, the first hook portion 21 and the third hook portion 23 are fixed to the fruit bunch shaft 31 and the branch 33B by the force (elastic force) that the twisted first shaft portion 11 tries to return to the original position, so that the first hook portion 21 and the third hook portion 23 are attracted. The tool 1 is hard to come off and can be easily attached. In particular, since the attracting tool 1 has a protrusion 24 at the tip of the first hook portion 21, the protrusion 24 also makes it difficult for the fruit bunch shaft 31 to come off.

Further, the attracting tool 1 attached in this way has appropriate flexibility and elasticity with a width of the second direction Y of 2.0 to 4.0 mm and a thickness of the third direction Z of 0.5 to 1.5 mm. The effect of the force (elastic force) to return to the fruit bunch 30, the stem 32 and the branch 33B is extremely small, and it is possible to attract the plant with less influence on the growth of the plant. ..

Further, in order to perform more reliable attachment, the third hook portion 23 shallowly hung on the branch 33B at the upper part of the fruit bunch is pushed downward as shown in FIG. At this time, in the attracting tool 1, the first shaft portion 11 and the second shaft portion 12 are moved before the first hook portion 21 is disengaged from the fruit bunch shaft 31 due to the flexibility of the first shaft portion 11 and the second shaft portion 12. Curve.

Further, in the case of tomatoes, as shown in FIG. 5, branches 33A, branches 33B, and branches 33C are alternately arranged toward the top of the fruit bunch 30. Therefore, in the attracting tool 1 in the present embodiment, in order to twist and attach the first shaft portion 11, the second hook portion 22 close to the first hook portion 21 is curved to the same side as the first hook portion 21. 3 The hook portion 23 has a shape curved to the opposite side to the second hook portion 22. That is, in the attracting tool 1, when the first shaft portion 11 is twisted, the second hook portion 22 is arranged on the side opposite to the first hook portion 21 hung on the fruit bunch shaft 31, and is the same as the first hook portion 21. The third hook portion 23 is arranged on the side.

Therefore, when attaching to the branch 33A one above the fruit bunch 30, as shown in FIG. 5, the second hook portion 22 is used to hang on the branch 33A, and when attaching to the branch 33B one above. The third hook portion 23 is used to hang it on the branch 33B as shown in FIG. As described above, in the attracting tool 1 in the present embodiment, the second hook portion 22 or the third hook portion 23 can be selectively used and efficiently attached to the branch 33A and the branch 33B.

Further, as shown in FIG. 7, the attracting tool 1 in the present embodiment can be used as an auxiliary when attracting diagonally by using a clip 35 on the horizontal cord 34. When the clip 35 is used for the horizontal string 34 to attract it diagonally, the stem 36 may loosen and the stems 36 may stick to each other depending on the number of clips 35 used and the installation distance. At this time, if the branches 37 and the leaves 38 are crowded, the air permeability is impaired, which tends to cause illness or the like. In such a situation, a better cultivation environment can be created by attracting the stem 36 and the like to the horizontal cord 34 by using the attracting tool 1 as an auxiliary.

Further, as shown in FIG. 8, the stem 36 is hung on the second hook portion 22 or the third hook portion 23, and the first hook portion 21 is hung on the horizontal cord 34 in a twisted manner, whereby the first shaft portion 11 is hung. The force (elastic force) to return to the original position and the protrusion 24 suppress the detachment of the horizontal cord 34 and the stem 36 due to the shaking during the attraction work, and adjust the stem 36 so that it does not loosen or stick to each other. Is possible. In addition, the flexibility of the attractor 1 allows the stem 36 to be gently held.

As described above, according to the attracting tool 1 in the present embodiment, the first hook portion 21 is hooked at an appropriate position of the fruit bunch shaft 31, and the upper portion is twisted so as to twist the first shaft portion 11 having flexibility and elasticity. It can be attached to the branches 33A, 33B, the stem 32, etc. by simply selecting and hooking either the second hook portion 22 or the third hook portion 23, and it is also easy to remove.

Further, the first hook portion 21 and the second hook portion 22 or the third hook portion 23 are brought together by the force (elastic force) generated by twisting the first shaft portion 11 to return to the original position of the first shaft portion 11. It is fixed to the fruit bunch shaft 31 and the branches 33A, 33B, the stem 32, etc., and is difficult to come off due to the growth of the stem 32 and the fruit bunch 30. In addition, the flexibility of the first shaft portion 11 makes the fruit bunch 30, the fruit bunch shaft 31 etc. , The influence on the branches 33A and 33B and the stem 32 is extremely small, and it is possible to attract the branches with less influence on the growth of the plant.

Further, in the attracting tool 1 in the present embodiment, since the second shaft portion 12 also has flexibility and elasticity, the second shaft portion 12 can be twisted in addition to the first shaft portion 11, and the second shaft portion 12 can be twisted. The first hook portion 21 and the second hook portion 22 or the third hook portion 23 are fixed to the fruit bunch shaft 31, the branches 33A, 33B, and the stem 32 by the returning force (elastic force) of the twelve. It is difficult to come off due to the growth of the stem 32 and the fruit bunch 30.

Further, in the attracting tool 1 in the present embodiment, the center of the curve of the first hook portion 21 is on the extension of the central axis of the first shaft portion 11, and the second hook portion 22 is the second with respect to the first shaft portion 11. Since it is on the same side as the 1 hook portion 21 and the second shaft portion 12 is at a position offset from the first shaft portion 11 to the second hook portion 22 side, the first hook portion 21 is located with respect to the first shaft portion 11. The center of the curve of the second hook portion 22 on the same side as the second hook portion 22 and the third hook extending in the opposite direction to the second hook portion 22 from the tip portion 12B of the second shaft portion 12 to the center of the second shaft portion 12. The center of the curve of the portion 23 is arranged at a position close to the central axis of the first shaft portion 11. Therefore, regardless of whether the second hook portion 22 or the third hook portion 23 is selected, the fruit bunch shaft held by the first hook portion 21 having the center of curvature on the extension of the central axis of the first shaft portion 11. The force applied to the first shaft portion 11 by 31 can be supported by the second hook portion 22 or the third hook portion 23 located near the central axis of the first shaft portion 11.

Further, since the attracting tool 1 in the present embodiment has a protrusion 24 protruding inward in a substantially J shape at the tip of the first hook portion 21, the fruit bunch shaft 31 hooked on the first hook portion 21 is provided. Even if it tries to come off from the first hook portion 21, it will be blocked by the protrusion 24, and it will be difficult to come off due to the growth of the stem 32 and the fruit bunch 30.

The attractant of the present invention is useful as an attractant for attracting stems and fruit clusters of tomatoes and the like, and in particular, it is easy to attach and remove, and it is difficult to remove due to the growth of stems and fruit clusters, due to the enlargement of the fruit clusters. It is suitable as an attractant capable of preventing the fruit bunch shaft from breaking or tearing.
