Description

本考案は、庭や路面、空き地に生える柔らかくて丈の低い雑草から固くて丈の高い雑草まで刈り取ることのできる草刈り鎌に関する。 The present invention relates to a mowing scythe that can cut from soft and low-length weeds growing in gardens, roads, and vacant lots to hard and tall weeds.

庭や路面に生える雑草を刈り取る草刈り鎌がいろいろと提案されている。例えば一般的な鎌は柄に対して刃がL字形に付いており、片手で手前に引き寄せるような動作で雑草を刈り取らなければならない。その他のものも片手で持つものは、中腰あるいは屈み腰の体勢で作業をしなければならないため、疲れる上に広範囲の雑草を刈るには時間がかかるという問題があった。また両手で持つものは刃の形や向きを変えて、立ち姿勢で払う・引く・押す等の動作で雑草を刈るようになっているが、固くて丈の高い雑草を刈るには、払うタイプのものは刃部と柄の間の付け根が衝撃に耐えられずに曲がる心配があり、刃に角度をつけたものは柄にねじれ方向の力がかかるので手に負担がかかり、引いたり押したりするものは動作の面で無理があるので、柔らかくて丈の低い雑草と固くて丈の高い雑草が混生している場所等を刈るのは困難であるという問題がある。 Various mowing scythes have been proposed to cut weeds that grow on gardens and road surfaces. For example, a common sickle has an L-shaped blade against the handle, and the weeds must be cut off using a single hand. Others with one hand have to work in the middle or crouched position, so that there is a problem that it takes time to cut a wide range of weeds as well as being tired. Those with both hands change the shape and direction of the blade, and use the standing posture to pay, pull, and push to cut weeds. In the case of the blade, there is a concern that the base between the blade part and the handle may not be able to withstand the impact and bend, and the one with an angled blade will apply a force in the twisting direction to the handle, so it will take a burden on the hand, pulling and pushing However, there is a problem in that it is difficult to cut a place where soft and low-length weeds and hard and high-length weeds are mixed, because the operation is impossible.

本考案は、両手で柄を持ち、立ったままの体勢で振り払うことにより、無理のない動作で柔らかくて丈の低い雑草から固くて丈の高い雑草まで刈ることのできる草刈り鎌を提供することにある。 The present invention is to provide a mowing scythe that can cut from soft and low-length weeds to hard and high-length weeds with a reasonable movement by holding the handle with both hands and shaking it off while standing is there.

本考案は、両手で持つ長柄１の先端に屈曲柄２を設けて、この屈曲柄２に鎌刃３を取付けるようにした草刈り鎌であって、湾曲する３本の鉄製の平板からなる屈曲柄２を介して、長柄１を鎌刃３の面に対して３５度傾けて取付けると共に、長柄１の軸の延長線が刃の長手方向中央部の点３ａを通るようにした。また長柄１の後端に握り部８を鎌刃３の面に対し直交するように取り付けたことを特徴とする草刈り鎌である。 The present invention is a mowing scythe in which a bent handle 2 is provided at the tip of a long handle 1 held by both hands, and a sickle blade 3 is attached to the bent handle 2, the bent handle being composed of three curved iron flat plates. 2, the long handle 1 was attached at an angle of 35 degrees to the surface of the sickle blade 3, and the extension of the shaft of the long handle 1 passed through the point 3a at the center in the longitudinal direction of the blade. The mowing scythe is characterized in that a grip portion 8 is attached to the rear end of the long handle 1 so as to be orthogonal to the surface of the scythe blade 3.

本考案の草刈り鎌は、長柄を鎌刃の面に対して３５度傾けて取付けることにより平面に近い状態に刈ることができる。また鎌刃と長柄との間に丈夫な屈曲柄を設けることにより刈るときの衝撃で曲がる心配もなく、長柄の軸の延長線が刃の長手方向中央部の点を通るようにすることにより衝撃を長柄の軸で受けて鎌刃と柄のねじれも解消されるので刈り易い。また両手で柄を持ち、立ったままの体勢で振り払うことにより無理のない動作で、柔らかくて丈の低い雑草から固くて丈の高い雑草まで刈ることができる上に、一振りで刈られる範囲も広くなり、短い時間で広い範囲を刈ることができるので効率的である。また鎌刃は蝶ネジで着脱できるようになっているので研磨や取替えが容易である。また長柄の握り部を鎌刃の面に直交するように設けたので手元で刃の面の角度を感じ取れ、手から外れることも無く、なぎ払い作業が容易であるなどの効果がある。 The mowing scythe of the present invention can be cut to a nearly flat state by attaching the long handle at an angle of 35 degrees to the surface of the sickle blade. In addition, by providing a durable bent handle between the sickle blade and the long handle, there is no fear of bending due to the impact when cutting, and the extension of the shaft of the long handle passes through the point at the center of the blade in the longitudinal direction, so the impact Is received by the long handle shaft, and the twist of the sickle blade and handle is eliminated, so it is easy to cut. In addition, by holding the handle with both hands and shaking it off while standing, you can mow from soft and low weeds to hard and tall weeds with a reasonable movement, and the range that can be cut with a stroke It is efficient because it can be widened and a wide area can be cut in a short time. The sickle blade is removable with a thumbscrew, so it is easy to grind or replace it. Further, since the long handle is provided so as to be perpendicular to the surface of the sickle blade, the angle of the blade surface can be sensed at hand, and there is an effect that the stripping operation is easy without being detached from the hand.

本考案を実施するための最良の形態を図面に基づき以下説明する。本考案の草刈り鎌は図１に示すように、藪などを払う造林鎌のように長柄１を両手で持ち振り払って雑草を刈るものであって、長柄１の先端に設けられた屈曲柄２に鎌刃３を組付けるようにしたものである。 The best mode for carrying out the present invention will be described below with reference to the drawings. As shown in FIG. 1, the mowing scythe of the present invention cuts weeds by holding and shaking a long handle 1 with both hands like a forested scythe for removing bushes and the like, and a bent handle 2 provided at the tip of the long handle 1. The scythe blade 3 is to be attached to the machine.

すなわち本考案の草刈り鎌は、長柄１の先端に三叉状の屈曲柄２の基端を差込み保持させ、この屈曲柄２に鎌刃３を交換自在に取付けたものである。屈曲柄２は、図２に示すように鉄製の平板から成り、長柄１の先端に差し込み保持される平板状の差込部２１と、この差込部２１から下方に３方に分岐し湾曲する三叉部２２と、三叉の先端に直交して一体的に設けられた鎌刃３の取付板２３とからなる。そして湾曲する三叉の中央の脚２２ａの端部を取付板２３の幅方向前方に、両側２２ｂ、２２ｃの端部を後方に溶接などで固着し、取付板２３がぐらつかないように安定的に保持するようにしてある。そして前記差込部２１を長柄１先端に差し込んで２本のネジ４にて締め付け固定する。 In other words, the mowing scythe of the present invention is obtained by inserting and holding the base end of a trifurcated bent handle 2 at the distal end of a long handle 1, and attaching a scissor blade 3 to the bent handle 2 in a replaceable manner. As shown in FIG. 2, the bent handle 2 is made of an iron flat plate, and has a flat plate-shaped insertion portion 21 inserted and held at the tip of the long handle 1, and branches downward from the insertion portion 21 in three directions and curves. It comprises a trifurcated portion 22 and a mounting plate 23 of the sickle blade 3 provided integrally and perpendicular to the tip of the trifurcated portion. Then, the end of the curved center leg 22a is fixed to the front in the width direction of the mounting plate 23, and the ends of both sides 22b and 22c are fixed to the rear by welding or the like, so that the mounting plate 23 is stably held without shaking. I have to do it. Then, the insertion portion 21 is inserted into the end of the long handle 1 and fastened and fixed with two screws 4.

また鎌刃３は図３に示すように鎌刃３の基端に一体的に直交させて取付板３１を設け、この取付板３１と前記屈曲柄２の取付板２３とを接合させて鎌刃３を組付けるようにする。すなわち図４に示すように鎌刃３の付け根に刃の長手方向中央部の点３ａの接線に対して直交するように取付板３１を一体的に取り付け、取付板３１に立設した2本のネジロッド５を屈曲柄２の取付板２３のネジ穴６に通して蝶ネジ７で止める。このとき屈曲柄２は図４に示すように長柄１を刃中央部の点３ａの刃の接線に対して刃の内側寄りに７度、図５に示すように長柄１を鎌刃３の面に対して上方へ３５度傾けるとともに、長柄１の軸の延長線が刃の長手方向中央部の点３ａを通るように作られている。 As shown in FIG. 3, the sickle blade 3 is provided with a mounting plate 31 integrally perpendicular to the base end of the sickle blade 3, and the mounting plate 31 and the mounting plate 23 of the bent handle 2 are joined to form a sickle blade 3. 3 should be assembled. That is, as shown in FIG. 4, the mounting plate 31 is integrally attached to the base of the sickle blade 3 so as to be orthogonal to the tangent to the point 3a at the center in the longitudinal direction of the blade. The screw rod 5 is passed through the screw hole 6 of the mounting plate 23 of the bent handle 2 and fixed with the thumb screw 7. At this time, as shown in FIG. 4, the bent handle 2 is formed by applying the long handle 1 to the inner side of the blade 7 degrees with respect to the tangent of the blade at the point 3a at the center of the blade, and as shown in FIG. , And the extension of the shaft of the long handle 1 passes through the point 3a at the center in the longitudinal direction of the blade.

また長柄１の後端に握り部８を鎌刃の面に対し直交するように設け、長柄１の長さは刃の長手方向中央部の点３ａから握り部８まで１２０ｃｍとなるようにしてある。 A grip 8 is provided at the rear end of the long handle 1 so as to be perpendicular to the surface of the sickle blade, and the length of the long handle 1 is 120 cm from the point 3a at the longitudinal center of the blade to the grip 8. .

本考案の草刈り鎌を用いて雑草を刈るときは、握り部８を握り片手を長柄１に添えて振り払うようにする。標準的な身長の大人が平坦な面を刈るときの握り部８の地面からの高さは９０ｃｍ〜１００ｃｍとなり、このとき水平面に対する鎌刃３の面は凡そ１０度〜１５度の角度になるので、斜面に立ち作業をするときは3０度の傾斜まで上方あるいは下方に向かって刈ることができる。 When mowing the weeds with the mowing scythe of the present invention, the user grips the grip portion 8 and shakes one hand with the long handle 1. The height of the grip portion 8 from the ground when an adult of standard height cuts a flat surface is 90 cm to 100 cm, and at this time, the surface of the sickle blade 3 with respect to the horizontal surface has an angle of about 10 to 15 degrees. When standing on a slope, you can cut upwards or downwards to a 30-degree slope.
