Description

【０００１】
【発明の属する技術分野】
本発明は、農芸分野において、トマト等の植物の茎を、この茎に略平行に張設される吊し紐とともに内側にクランプして茎が倒れないように保持する植物用茎ホルダーに関するものである。
【０００２】
【従来の技術】
この種の植物用茎ホルダーは、特公平５−１５４０５号公報などで知られており、図７は同公報に記載された茎ホルダーを示している。同図の茎ホルダー３０は、第１の挟持半体３１の中間部３１ａが断面コ字形をなし、その内側に第２の挟持半体３２の中間部３２ａを挟み込んでだ状態にして第１の挟持半体３１と第２の挟持半体３２とを、ピン３３を用いて連結した構成である。各挟持半体３１，３２は、その一端側が両者で筒状を形成可能な円弧状部３１ｂ，３２ｂをなし、他端側が両者でハ字形に延びた操作部３１ｃ，３２ｃに形成されている。また、各中間部３１ａ，３２ａにあって円弧状部側には、円弧状部３１ｂ，３２ｂの開口に通じ、かつ円弧状部３１ｂ，３２ｂが同図の如く閉じることにより間に吊し紐３４を挟持可能な凹凸部（同図中、符号Ａの部分）が設けられている。更に、各円弧状部３１ｂ，３２ｂは、各操作部３１ｃ，３２ｃに設けられた貫通孔３１ｄ，３２ｄを通し、その両端を円弧状部３１ｂ，３２ｂの対応する外周に係止したＣ形ばね３４により互いに当接して閉じる方向へ付勢されている。
【０００３】
そして、この茎ホルダー３０を使用するには、各操作部３１ｃ，３２ｃをＣ形ばね３４の付勢力に抗して間隔を狭めると、両円弧状部３１ｂ，３２ｂが前記凹凸部とともに開く。開いた両円弧状部３１ｂ，３２ｂの間には植物の茎３６を、吊し紐３５とともに入れ込む。前記凹凸部の間に吊し紐３５を位置させた状態で、操作部３１ｃ，３２ｃから指を離す。すると、両円弧状部３１ｂ，３２ｂがばね３４の付勢力により閉じる。この結果、茎ホルダー３０は吊し紐３５に対し前記凹凸部の挟持力により固定され、また両円弧状部３１ｂ，３２ｂの内側に茎３６を位置させてその茎３６を痛めることなく倒れないように保護できる。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の茎ホルダー３０にあっては、円弧状部３１ｂ，３２ｂがばね３４の付勢力により閉じた状態に保持される構造であることから、その保持状態の確実性に欠け、例えば作業中、操作部３１ｃ，３２ｃに当たると開状態になって茎３６が円弧状部３１ｂ，３２ｂから抜けでるという虞もあった。この場合、ばね３４の付勢力を増大して、円弧状部３１ｂ，３２ｂの閉状態をより強固に保持すると、円弧状部３１ｂ，３２ｂを開状態にするときにその付勢力に比例した力を要し、疲れ易くなるという問題がある。
また、茎ホルダー３０は、植物に用いられて農薬などの影響を受けることから、Ｃ形ばね３４を用いると、錆びたり、腐食が進んで、当初の付勢力が次第に減衰し使用できなくなったり、寿命が速く繰り返し使用することができなくなる。しかも、構成部品が４点と多く、組み付けも挟持半体３１，３２にＣ形ばね３４を介在させることから時間が係り、コトス低減が図り難い。
【０００５】
本発明は、上記問題点を全て解消し、茎の保持状態をより確実に保持できることに加え、部品点数が少なく、組立も容易にして製造コストを低減でき、しかも繰り返し使用しても使用状態を常に維持可能な植物用茎ホルダーを提供することにある。他の目的は、以下に説明する内容の中で順次明らかにする。
【０００６】
【課題を解決するための手段】
本発明は上記目的を達成するため、互いの中間部が重ねられ、かつ軸支されて鋏のように動かされる第１の挟持半体と第２の挟持半体とからなり、前記両挟持半体がその一端側に筒状を形成可能な円弧状部を、他端側に操作部をそれぞれ一体に形成しているとともに、前記各中間部に設けられて前記円弧状部の開口に通じ、かつ両円弧状部が筒状を形成して閉じられることにより間に入れられる吊し紐を挟持可能な部分を有している植物用茎ホルダーであって、前記両挟持半体の一方側にラチェット歯を、他方側に前記ラチェット歯に対応した係止爪をそれぞれ一体に形成しており、前記係止爪を前記ラチェット歯に係合することによって、前記両円弧状部を筒状の閉状態に解除可能に保持する構成としたものである。
【０００７】
この構成によれば、茎ホルダーを使用するには、各円弧状部が開口している状態で、両円弧状部の開口からトマト等の植物の茎を、吊し紐とともに入れて、前記挟持可能な部分の間に吊し紐を位置させ、両円弧状部を閉じる方向へ操作部を動かし、かつラチェット歯に係止爪を係合させる。この係合により、茎ホルダーは吊し紐に対し前記挟持可能な部分の挟持力により固定され、両円弧状部の内側に茎を痛めないように拘束してその茎を倒れないように保護する。
【０００８】
【発明の実施の形態】
以下、本発明の実施の形態について図面を参考にしつつ説明する。図１乃至図４は本発明の一実施例として示す植物用茎ホルダー構造を示すもので、図１はその全体外観図、図２はその概略分解図、図３は茎ホルダーを下側から見た裏面図、図４は図１のＡ−Ａ線に沿って断面した断面図である。
【００１０】
本発明の植物用茎ホルダー１は、図１に示される如く、共に樹脂成形体である第１の挟持半体２と第２の挟持半体３とを備え、両挟持半体２，３の中間部４，５が重ねられかつ軸支されて鋏のように動かされる点、両挟持半体２，３の一端側には筒状を形成可能な円弧状部６，７が一体に形成され、他端側には操作部８，９が一体に形成されている点、前記各中間部２，３に形成されて円弧状部６，７の開口に通じ、かつ両円弧状部６，７が筒状を形成して閉じられることにより間に入れられる吊し紐２０（図５を参照）を挟持可能な凹凸部１８，１９を有している点で従来とほぼ同様な構成となっている。要部構成は、両挟持半体２，３の組み付け構造と、各円弧状部６，７を開状態に保持するラチェット歯１０および係止爪１１の構造などであり、以下、それら要部を主に詳述する。
【００１１】
（第１の挟持半体構造）第１の挟持半体２は、図２から図４に示される如く、中間部４の前後に設けられている円弧状部６の先端６ａと操作部８とがほぼ直線上に位置している。その内、中間部４は、中心よりずれた側部よりに設けられた上下に貫通した取付孔１３と、円弧状部６側にあって円弧状部６の開口にその一部が通じている上下方向の貫通孔として設けられた凹部１８と、操作部８側に張り出した状態に設けられた膨出部１２とを有している。上下肉厚としては、円弧状部６と連結している部分から前記凹部１８が形成されている部分４ｂが円弧状部６の上下幅とほぼ一致し、取付孔４ａに接近する側部の一部４ｃが部分４ｂよりも薄く、部分４ｂ，４ｃおよび膨出部１２を除く残りの部分４ｄが部分４ｃよりもさらに薄く形成されている。
【００１２】
ここで、取付孔１３は、上側孔１３ａが下側孔１３ｂに対し大きく設けられている。凹部１８には、部分４ｂの肉厚内にあって、これを形成している貫通孔の孔内端面から側部へ向けて逃げ孔１８ａが形成されている。膨出部１２は、図３に示す如く内側が空洞に設けられており、外周端面の一部にラチェット歯１０を、またこのラチェット歯１０と間隔をおいて操作部８がそれぞれ一体に形成されている。ラチェット歯１０は２個の歯で構成されるとともに、その各歯筋が上下方向に設定されている。操作部８は板状をなし、両側面に設けられた複数個の上下突起８ａを有し、また基部下側が切欠されて膨出部１２の外周との間にガイド溝８ｂを形成している。なお、ラチェット歯１０は１個ないしは３個以上で構成することも可能であり、操作部８もこの形態以外であってもよい。
【００１３】
（第２の挟持半体構造）第２の挟持半体３も、中間部５の前後に設けられている円弧状部７の先端７ａと操作部８とがほぼ直線上に位置している。そして、円弧状部７は先端７ａに段部７ｂを有し、両円弧状部６，７を閉じた状態で段部７ｂが第１の挟持半体３の先端６ａに設けられた段部６ｂに嵌合されるようになっている。中間部５は、略中央に設けられて一部が側部まで達している円形の窪み部５ａと、この窪み部５ａの底面に突設された枢軸１４と、円弧状部７の開口基部側に設けられて前記凹部１８と係合可能な凸部１９とを有し、またこの凸部１９と反対側には操作部９が設けられている。
【００１４】
ここで、窪み部５ａは、中間部５に他方の中間部４を重ねた状態で、中間部４の部分４ｃの下部側が内部に嵌入されるよう設定され、この窪み部５ａの略中央部に枢軸１４が一体に突出形成されている。この枢軸１４は、図４の如く軸先端側が中間部５の一般部の肉厚よりも突出し、その突出部に傘状の抜止部１４ａを形成している。この抜止部１４ａは、軸先端側から下方に設けられたスリット１４ｂにより分割されており、各分割部がスリット１４ｂ側に弾性変形可能となっている。符号５ｂは窪み部５ａの底面に枢軸１４を一体成形するための型抜き孔であり、抜止部１４ａの突出径がこの孔の大きさで決まる。
また、前記凸部１９は、上面が図２の如く中間部５の一般部に対し面一になっているが、下部側が欠肉されて薄く形成され、円弧状部６，７を閉じた状態で図３の如く凹部１８の逃げ孔１８ａ内に少し入り込む。このように、凸部１９が逃げ孔１８ａに入り込むことにより、吊し紐２０（図６を参照）が凹凸部１８，１９の間に強く挟持され、吊り紐２０に対し茎ホルダー１が固定される。
【００１５】
前記操作部９は板状をなし、外側面に操作部８の上下突起８ａに相当する上下突起９ａを有している。この操作部９には、円弧状部７の湾曲側に位置する内側面にあって、中間部５側に係止片１５が一体に突出形成され、その係止片１５に係止爪１１が設けられている。係止片１５は、円弧状部６，７が閉状態にあるとき操作部８のガイド溝８ｂを通って、前記ラチェット歯１０の下部を外側から覆う長さに形成されている。この係止片１５には、係止爪１１がその先端側にあってラケット歯１０に対応して設けられるとともに、係止爪１１よりも先端に補助操作部１６が一体に形成されている。この補助操作部１６は、操作部９に対し所定傾斜角で対抗しており、係止爪１１がラチェット歯１０に係合している状態から、係合を解除する際に指当て用として使われる。なお、前記係止片１５の上端面には、図１に示される如く規制ピン１７が設けられている。
【００１６】
（組み付け操作）以上の両挟持半体２，３は、例えば、図２に示す如く枢軸１４が上になるよう第２の挟持半体３を置いておく。その上に枢軸４が取付孔１３に押し入れられるように中間部５に第１の挟持半体３の中間部４を重ねる。そして、中間部４，５を上下方向から押圧すると、枢軸４は取付孔１３に対し下側から入り込み、その抜止部１４ａが下側孔１３ｂから上側孔１３ａに達したとき、スリット１４ｂの存在により内側に撓んで径小の上側孔１３ａ内に突出し、この突出と同時に復元して抜けなくなる。このように連結した状態では、中間部４の部分４ｃが中間部５の窪み部５ａ内に嵌合し、両挟持半体２，３が枢軸１４を中心にして所定の範囲だけ回動可能に組み立てられる。
【００１７】
この回動範囲は、図１，図３に示す如く円弧状部６，７が閉じて筒状を形成している状態から、ラチェット歯１０と係止爪１１との係合を解除して、操作部８に対し補助操作部１６が図３の矢印方向へ押されて当たるまでである。但し、この実施例では、操作部８に対し補助操作部１６が当接する前の段階で、前記した規制ピン１７が当たるようになっている。なお、この場合でも、円弧状部６，７の開口をより大きくしたいときには、補助操作部１６を図１の矢印Ａで示す下向きに押しながら、規制ピン１７を操作部８のガイド溝８ｂ内を通過させて、図３の想像線の位置まで移動することができる。
【００１８】
（使用要領）図５，図６は以上構成の茎ホルダー１を用いてトマトの茎を保持する操作例を示している。同図中、符号２０は、トマトの茎２１に沿って上下方向に張設された吊り紐である。本発明の茎ホルダー１は、このような吊り紐２０に対し、通常、複数個を固定して取り付けて、茎２１が不用意に倒れないように各部で保持するものである。作業要領は、図５の如くラチェット歯１０と係止爪１１との係合を解除し、円弧状部６，７が開口される方向へ補助操作部１６を前記したように動かす。そして、両円弧状部６，７の開口からトマトの茎２１を、吊し紐２０と共に入れて、前記凹凸部１８，１９の間に吊し紐２０を位置させた状態で、両円弧状部６，７を閉じる方向へ操作部８，９を動かし、かつラチェット歯１０に係止爪１１を係合される。図６はこのようにして係合させた作業完了状態で示している。茎ホルダー１は、ラチェット歯１０と係止爪１１との係合によって円弧状部６，７を閉じた状態に確実に保持されている。したがって、茎ホルダー１は、吊し紐２０に対し前記凹凸部１８，１９の挟持力に応じた強さで固定される。同時に、両円弧状部６，７の内側に茎２１を拘束してその茎２１の不用意な倒れを防ぐことができる。
【００１６】
【発明の効果】
以上説明したとおり、本発明の植物用茎ホルダーはね従来品に対し次のような効果を有している。
▲１▼、各円弧状部がラチェット歯と係止爪との係合により閉状態に保持されるようにしたことから、従来の付勢部材を用いる構造に対し、前記係合を解除操作しない限り開かないので閉状態の確実性に優れている。また、錆びたり、付勢力が減衰するというような問題もなく、長期に繰り返し使用しても円弧状部を閉状態に保持できる
▲２▼、前記ラチェット歯および係止爪が対応する挟持半体に一体に形成されていることから、従来のＣ形ばねなどの別部品を必要とせず、部品点数を減少して、コストを低減できる。加えて、組み付け時には従来の如くＣ形ばねを介在させることなく第１，第２の挟持半体を軸支するだけなので、作業性が良好となり、この点からもよりコストの低減が達成される。
▲３▼、使用する場合において、植物の茎を両円弧状部内に入れるまでの操作過程では、両円弧状部を開状態にすべく各操作部を操作する。この場合、従来の如くＣ形ばねの付勢力に抗して開状態にする方法だと、比較的大きな力を要して、多数の茎ホルダーを適用する場合にくたびれ易い作業となる。これに対し、本発明の如く付勢手段を設けない構造では多数の茎ホルダーを適用する場合にも、前記開状態にするのに力を要せず、その分だけ疲労も軽減され作業改善が図られる。

BACKGROUND OF THE INVENTION
The present invention relates to a plant stem holder for holding a stem of a plant such as a tomato or the like together with a hanging string stretched substantially parallel to the stem so as to prevent the stem from falling down in the agricultural field. is there.
[0002]
[Prior art]
This kind of plant stem holder is known from Japanese Patent Publication No. 5-15405, and FIG. 7 shows the stem holder described in the publication. The stem holder 30 in the figure has a first sandwiching half 31 with an intermediate portion 31a having a U-shaped cross section, and an intermediate portion 32a of the second sandwiching half 32 sandwiched inside thereof. The sandwiching half 31 and the second sandwiching half 32 are connected using a pin 33. Each of the holding halves 31 and 32 has arc-shaped portions 31b and 32b whose one end side can form a cylindrical shape with both ends, and the other end side is formed with operating portions 31c and 32c extending in a C shape with both ends. Further, in each of the intermediate portions 31a and 32a, on the side of the arc-shaped portion, it leads to the openings of the arc-shaped portions 31b and 32b, and the arc-shaped portions 31b and 32b are closed as shown in FIG. Is provided with a concavo-convex portion (a portion indicated by symbol A in the figure). Further, each arcuate part 31b, 32b passes through a through hole 31d, 32d provided in each operation part 31c, 32c, and a C-shaped spring 34 having its both ends locked to the corresponding outer periphery of the arcuate parts 31b, 32b. Are urged in the direction of contacting and closing each other.
[0003]
And in order to use this stem holder 30, if each operation part 31c, 32c is narrowed against the urging | biasing force of the C-shaped spring 34, both arc-shaped parts 31b, 32b will open with the said uneven part. A plant stem 36 is inserted together with the hanging string 35 between the open arcuate portions 31b and 32b. With the hanging strap 35 positioned between the concave and convex portions, the finger is released from the operation portions 31c and 32c. Then, both arcuate portions 31 b and 32 b are closed by the biasing force of the spring 34. As a result, the stem holder 30 is fixed to the hanging strap 35 by the clamping force of the concave and convex portions, and the stem 36 is positioned inside the arcuate portions 31b and 32b so as not to fall down without damaging the stem 36. Can be protected.
[0004]
[Problems to be solved by the invention]
However, in the conventional stem holder 30, since the arc-shaped portions 31b and 32b are held in a closed state by the urging force of the spring 34, the holding state is not sure. In the middle, when it hits the operation portions 31c and 32c, the stem 36 may be opened and the stem 36 may come off from the arc-shaped portions 31b and 32b. In this case, if the biasing force of the spring 34 is increased and the closed state of the arcuate portions 31b and 32b is held more firmly, a force proportional to the biasing force is applied when the arcuate portions 31b and 32b are opened. In short, there is a problem that it becomes easy to get tired.
In addition, since the stem holder 30 is used in plants and is affected by agricultural chemicals or the like, when the C-shaped spring 34 is used, rusting or corrosion progresses, and the initial urging force gradually attenuates and cannot be used. It has a long life and cannot be used repeatedly. In addition, there are many component parts, and since the C-shaped springs 34 are interposed in the holding halves 31 and 32, it takes time, and it is difficult to reduce cost.
[0005]
The present invention eliminates all of the above problems and more reliably holds the stem holding state, and also reduces the number of parts, facilitates assembly, reduces manufacturing costs, and can be used even after repeated use. It is to provide a plant stem holder that is always maintainable. Other objects will be clarified sequentially in the contents described below.
[0006]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention comprises a first sandwiching half and a second sandwiching half that are overlapped with each other and pivotally supported to move like a scissors. The body is integrally formed with an arcuate part capable of forming a cylindrical shape on one end side, and an operation part is integrally formed on the other end side, and is provided in each of the intermediate parts, leading to the opening of the arcuate part, And it is a plant stem holder which has a part which can pinch a hanging string put between both arc-shaped parts by forming a cylinder shape, and is on one side of the both holding halves. A latching claw corresponding to the ratchet tooth is integrally formed on the other side of the ratchet tooth, and by engaging the latching claw with the ratchet tooth, both the arcuate portions are closed in a cylindrical shape. The configuration is such that the state is releasably held.
[0007]
According to this configuration, in order to use the stem holder, a stem of a plant such as a tomato is put together with a hanging string from the opening of both arc-shaped portions in a state where each arc-shaped portion is open, The hanging strap is positioned between the possible portions, the operating portion is moved in the direction of closing both arc-shaped portions, and the latching claw is engaged with the ratchet teeth. By this engagement, the stem holder is fixed to the hanging strap by the clamping force of the portion that can be clamped, and is restrained so as not to damage the stem inside both arcuate portions so as to prevent the stem from falling down. .

(Assembly operation) The both sandwiching halves 2 and 3 are placed with the second sandwiching half 3 so that the pivot 14 is on the upper side as shown in FIG. 2, for example. On top of that, the intermediate part 4 of the first clamping half 3 is overlapped with the intermediate part 5 so that the pivot 4 is pushed into the mounting hole 13. When the intermediate portions 4 and 5 are pressed from above and below, the pivot 4 enters the mounting hole 13 from below, and when the retaining portion 14a reaches the upper hole 13a from the lower hole 13b, the presence of the slit 14b. It bends inward and protrudes into the small-diameter upper hole 13a. In such a connected state, the portion 4c of the intermediate portion 4 is fitted into the recess portion 5a of the intermediate portion 5 so that both sandwiched halves 2 and 3 can rotate by a predetermined range around the pivot shaft 14. Assembled.
[0017]
As shown in FIGS. 1 and 3, the rotation range is such that the engagement between the ratchet teeth 10 and the locking claws 11 is released from the state in which the arc-shaped portions 6 and 7 are closed to form a cylindrical shape, This is until the auxiliary operation unit 16 is pushed in the direction of the arrow in FIG. However, in this embodiment, the restriction pin 17 is in contact with the operation unit 8 before the auxiliary operation unit 16 comes into contact with the operation unit 8. Even in this case, when the opening of the arc-shaped portions 6 and 7 is desired to be larger, the restricting pin 17 is pushed in the guide groove 8b of the operating portion 8 while pushing the auxiliary operating portion 16 downward as indicated by the arrow A in FIG. It can be moved to the position of the imaginary line in FIG.
[0018]
(Guide to use) FIG. 5 and FIG. 6 show an operation example for holding a tomato stem using the stem holder 1 having the above configuration. In the figure, reference numeral 20 denotes a hanging string stretched in the vertical direction along the tomato stem 21. The stalk holder 1 of the present invention is normally attached to such a hanging strap 20 by fixing a plurality of the stalk holders 1 so that the stalk 21 does not fall inadvertently. As shown in FIG. 5, the operation procedure releases the engagement between the ratchet teeth 10 and the locking claws 11 and moves the auxiliary operation portion 16 in the direction in which the arc-shaped portions 6 and 7 are opened as described above. And the tomato stem 21 is put together with the hanging string 20 from the opening of both the arc-shaped parts 6, 7, and the both arc-shaped parts are positioned with the hanging string 20 positioned between the uneven parts 18, 19. The operating portions 8 and 9 are moved in the direction of closing the pins 6 and 7, and the latching claws 11 are engaged with the ratchet teeth 10. FIG. 6 shows the operation completed state engaged in this way. The stem holder 1 is securely held in a state in which the arc-shaped portions 6 and 7 are closed by the engagement of the ratchet teeth 10 and the locking claws 11. Accordingly, the stem holder 1 is fixed to the hanging strap 20 with a strength corresponding to the clamping force of the concave and convex portions 18 and 19. At the same time, the stem 21 can be restrained inside the arcuate portions 6 and 7 to prevent the stem 21 from being accidentally collapsed.

【The invention's effect】
As described above, the plant stem holder of the present invention has the following effects over the conventional product.
(1) Since each arcuate portion is held in a closed state by the engagement of the ratchet teeth and the locking claw, the engagement is not released from the structure using the conventional biasing member. Since it does not open as long as possible, it has excellent certainty in the closed state. In addition, there is no problem of rusting or damping of the urging force, and the arcuate portion can be kept closed even after repeated use over a long period of time. (2) The clamping half corresponding to the ratchet teeth and the locking claws Therefore, it is possible to reduce the cost by reducing the number of parts without requiring another part such as a conventional C-shaped spring. In addition, since only the first and second clamping halves are pivotally supported without interposing a C-shaped spring as in the prior art at the time of assembly, workability is improved, and cost reduction is further achieved from this point. .
{Circle around (3)} In the case of use, in the operation process until the plant stems are put into both arc-shaped portions, each operating portion is operated to open both arc-shaped portions. In this case, if the method is to open against the urging force of the C-shaped spring as in the prior art, a relatively large force is required, and this is an operation that tends to be difficult when applying a large number of stem holders. On the other hand, in the structure in which the biasing means is not provided as in the present invention, even when a large number of stem holders are applied, no force is required to make the open state, and the fatigue is reduced correspondingly, and the work is improved. Figured.
