Description

この考案は、テコの原理を用いて根深い雑草を容易に除去するための用具に関する。 This invention relates to a tool for easily removing deep-rooted weeds using the principle of leverage.

従来より、種々の除草用具が利用されているが、本案に示すようなテコの原理を用いたものは見あたらない。 Conventionally, various weeding tools have been used, but there is no one that uses the lever principle as shown in this proposal.

除草は園芸等には必須の作業である。育てる植物以外に自然発生する雑草は無用物として除去されるが、手でむしるだけでは根は除去しにくいので、種々の除草用具が開発され、利用されてきた。小型のスコップ状のものや小型鎌に連続凹凸刃をつけたもの、あるいは足で踏んで土中に入れて使用するものなどがある。
根の深い雑草ではそれを根ごと掘り出すのは重労働であり、より簡便に利用できるとともに小労力にて雑草を根こそぎ除去できる手段が望まれているのが現状である。
本案は以上に鑑みて、より容易に雑草を根ごと除去するために考案されたものであって、テコの原理を利用した新規かつ有用なる用具を提供するものである。Weeding is an essential task for horticulture. Naturally occurring weeds other than the plants to be grown are removed as waste, but roots are difficult to remove by hand, so various weeding tools have been developed and used. There are small scoops, small sickles with continuous uneven blades, or those that are stepped on in the soil and used.
With deep-rooted weeds, it is hard labor to dig up the roots, and there is a demand for a means that can be used more easily and can be removed with a small effort.
In view of the above, the present invention has been devised in order to more easily remove weeds with their roots, and provides a new and useful tool using the principle of leverage.

課題を解決する手段として本案は以下の構成とした。
すなわち、主棒としての適宜長の棒体上部にハンドルを設け、該主棒下部側面に、別棒体の鋭角折曲によるフレームを設け、主棒下端に、その下端に刃を有する挿入棒を突設する。本案は以上の構成よりなる除草用具である。As a means for solving the problems, the present plan has the following configuration.
That is, a handle is provided at the upper part of a suitably long rod as a main rod, a frame by acute bending of another rod is provided at the lower side of the main rod, and an insertion rod having a blade at the lower end is provided at the lower end of the main rod. Project. The present plan is a weeding tool configured as described above.

本案によれば、除去しようとする雑草の根近傍土中に挿入棒を挿入し、主棒を傾けることにて刃が雑草の根をとらえ、主棒をさらに傾けてテコの原理にて雑草を根ごと容易に引き抜いて除去することのできる、有用なる用具を得ることができる。また、フレームに足をかけることにて、土中への挿入も容易となり、挿入棒の差し替え手段を用いることにて、除去しようとする雑草に応じた対応が可能となる。 According to the present plan, an insertion rod is inserted into the soil near the root of the weed to be removed, the blade catches the root of the weed by tilting the main rod, and the main rod is tilted further and the weed is rooted by lever principle. Useful tools that can be easily pulled out and removed can be obtained. In addition, it is easy to insert into the soil by putting a foot on the frame, and it is possible to cope with the weed to be removed by using the means for replacing the insertion rod.

以下、本考案の実施形態について説明する。
図において、１は主棒で、適宜長の鉄製管体であり、その上縁には主棒よりやや太い管体によるハンドル２が主棒に対し直角に固着される。３は主棒よりやや細い鉄製管体を鋭角に折曲して正面視三角形としたフレームで、主棒下部側面に２個が対称形に固着される。
このフレームの下部は主棒に対し垂直である。４は鉄製棒体による挿入棒で、主棒下端内に挿入固着される。５は挿入棒下端に形成される刃である。挿入棒下部は鍛造にて下端に向かうにつれて平たく変形し、挿入棒外径より張り出した平板状部分中央を切除して、図４にて示すように略直角の切除部分が形成されて刃となる。すなわち、刃外端を鋭角とし、刃中央は略直角に形成される。
本案を使用するには、除去しようとする雑草の根近傍に挿入棒を突き刺し、ハンドルを持って主棒を倒す。これにて刃にて草の根が把握されつつ上方に持ち上がり、後は手で容易に抜くことができる。この作業時において、刃が作用点、フレームの地面に接している部分が支点、ハンドルが力点となり、作用点と支点間距離に比べて支点と力点間距離が大きいので、少ない力にて大きな引き抜き力を得ることができる。また、フレーム下部は主棒に対し垂直であり、ここに足を乗せて体重をかけることにて主棒の地面への挿入が容易となる。刃の形状は図４にて示すように、平たくした棒体を略直角に切除した形状であり、この切除部中央に草の根をあてがって上述の作業を行うことにて根に刃が食い込んで抜き取りが容易となる。なお、主棒に対するフレームの張り出し方向に対して刃幅方向は直角の関係である。Hereinafter, embodiments of the present invention will be described.
In the figure, reference numeral 1 denotes a main rod, which is an appropriately long iron tube, and a handle 2 made of a tube slightly thicker than the main rod is fixed to the upper edge of the main rod at a right angle to the main rod. Reference numeral 3 denotes a frame formed by bending a steel pipe body slightly thinner than the main rod at an acute angle to form a front view triangle, and two are fixed symmetrically on the lower side surface of the main rod.
The lower part of this frame is perpendicular to the main bar. Reference numeral 4 denotes an insertion rod made of an iron rod, which is inserted and fixed in the lower end of the main rod. Reference numeral 5 denotes a blade formed at the lower end of the insertion rod. The lower part of the insertion rod deforms flatly toward the lower end by forging, and the center of the flat plate-like portion protruding from the outer diameter of the insertion rod is excised, and a substantially perpendicular excision is formed as shown in FIG. . That is, the outer edge of the blade is an acute angle, and the center of the blade is formed at a substantially right angle.
To use this plan, stab an insertion rod near the root of the weed to be removed, and hold the handle to defeat the main rod. With this, the grass roots are grasped by the blade and lifted upward, and thereafter can be easily pulled out by hand. During this work, the blade is the point of action, the part of the frame that is in contact with the ground is the fulcrum, and the handle is the force point. The distance between the fulcrum and the force point is greater than the distance between the point of action and the fulcrum. You can gain power. Also, the lower part of the frame is perpendicular to the main bar, and it is easy to insert the main bar into the ground by putting a foot on it and applying weight. As shown in FIG. 4, the shape of the blade is a shape obtained by cutting a flat rod body at a substantially right angle, and by applying the above-mentioned operation with the grass root in the center of the cut portion, the blade bites into the root and is extracted. Becomes easy. The blade width direction is perpendicular to the direction in which the frame extends from the main bar.

図５は本案の他例を示すものである。前例にて挿入棒は主棒に固定一体化した構成としたが、本例は挿入棒の付け替えを可能とするべく、主棒下部に貫通孔を２個所並べて設け、この孔に対応する挿入棒位置に孔を穿設し、挿入棒は主棒に対しスライド可能として、これらの孔を一致させてボルトとナットの締め込みにて主棒に対し挿入棒を固定可能としたものである。刃のサイズと形状は、除去しようとする雑草に適合して選択することが望ましく、種々の刃の挿入棒を用意して、必要に応じて付け替えて用いることで最適な除去作業が可能となる。刃は既述の例では略直角の切除部としたが、他の角度を用いることも可能で、実験では８０度から１００度の範囲が適当と思われる。なお、フレームは１個のみ設けてもよい。以上、本案について記したが本案は刃にて根をとらえつつテコの原理にて少ない力で根を引き抜いて除去するところにその特徴を有している。
従来品にはこのようなものがなく、その大半は手に持った用具を用いて除草するものであり、これでは根深い草を根ごと除去するには適さない。また、その下部を平板化したスコップ状の用具もあるが、足で踏みつけて土中に挿入はできるが、根の下部まで掘り起こさねばならず労力負担が大きい。これに対し本案は上述のごとく、刃で把握した根をテコの原理にて引き抜く方式のため、従来品にない利便性を有するものとなったのである。
なお、初例では管体にて主部を形成したが、棒体にて形成してもよい。なお、挿入棒は力の加わる部分のため棒体が適している。刃幅や刃の切除角度は適宜に設定できるが、刃幅が広すぎると土中への挿入がしにくく、狭すぎると根をとらえにくい。刃の切除角度が狭すぎると所定刃幅にするには刃長を長くしなければならず、広すぎると根の把握が難しく根を引き抜きにくくなり、既述のように９０度前後が適している。
以上説明したように、本案は構造簡単でその扱いも容易であり、根ごと除草する際に有効なる用具を得ることができる。FIG. 5 shows another example of the present plan. In the previous example, the insertion rod was fixed and integrated with the main rod. However, in this example, in order to allow the insertion rod to be replaced, two through holes are arranged in the lower portion of the main rod, and the insertion rod corresponding to this hole is provided. A hole is formed at a position, the insertion rod can be slid with respect to the main rod, and these holes are made to coincide with each other so that the insertion rod can be fixed to the main rod by tightening a bolt and a nut. It is desirable to select the blade size and shape in accordance with the weeds to be removed. By preparing various blade insertion rods and using them as necessary, optimum removal work can be performed. . Although the blade is a substantially right-angled cut portion in the above-described example, other angles can be used, and in the experiment, a range of 80 degrees to 100 degrees seems appropriate. Only one frame may be provided. As mentioned above, although this plan was described, this plan has the characteristic in which a root is pulled and removed by a lever principle with a little force while capturing the root with a blade.
There is no such thing in the conventional products, and most of them are weeded with tools held in hand, which is not suitable for removing deep-rooted grasses with their roots. There is also a scoop-like tool with a flat bottom, but it can be stepped on with a foot and inserted into the soil, but it must be dug up to the bottom of the root, which is labor intensive. On the other hand, as described above, the present plan has a convenience not found in conventional products because the root grasped by the blade is extracted based on the principle of leverage.
In addition, although the main part was formed with the pipe in the first example, you may form with a rod. In addition, since the insertion rod is a portion where force is applied, a rod is suitable. The blade width and the cutting angle of the blade can be set as appropriate, but if the blade width is too wide, it is difficult to insert into the soil, and if it is too narrow, it is difficult to catch the root. If the cutting angle of the blade is too narrow, the blade length must be increased to achieve a predetermined blade width, and if it is too wide, it is difficult to grasp the root and it is difficult to pull out the root, and as described above, about 90 degrees is suitable. Yes.
As described above, the present plan is simple in structure and easy to handle, and can provide an effective tool when weeding the whole root.
