鎌本体２は、金属製の板状であって、使用者の手前側に引き寄せて草木を切断するための刃部22と、第１柄部材11の先端部11ａに差し込まれる板状のシャンク部21と、を有している。シャンク部21は、取着用貫孔21ｇ，21ｇを２つ有している。 The sickle body 2 has a metal plate shape, a blade portion 22 for cutting the plant by drawing it toward the user's near side, and a plate-shaped shank portion inserted into the tip end portion 11a of the first handle member 11 And 21. The shank portion 21 has two attachment through holes 21g and 21g.

そして、図２乃至図４に示すように、第１柄部材11の先端部11ａに、鎌本体２のシャンク部21と共に一対の板状のＬ字状部材３，３を取着している。
Ｌ字状部材３は、シャンク部21の取着用の貫孔21ｇ，21ｇに対応する２つの貫通孔31ｇ，31ｇを有する取付帯板部31と、取付帯板部31から直交状に連設（直角に形成）された板状の起立片部32と、を有している。 As shown in FIGS. 2 to 4, a pair of plate-like L-shaped members 3 and 3 are attached to the distal end portion 11 a of the first handle member 11 together with the shank portion 21 of the sickle body 2.
The L-shaped member 3 includes an attachment band plate portion 31 having two through holes 31g, 31g corresponding to the through holes 21g, 21g for attaching the shank portion 21, and an orthogonal connection from the attachment band plate portion 31 ( And a plate-like standing piece 32 formed at a right angle.

そして、一対のＬ字状部材３，３の起立片部32，32が相互に反対方向に突出するように配設し、一対の取付帯板部31，31でシャンク部21を挟持し、第１柄部材11の先端面から凹設した差込凹部11ｂに差し込んでいる。
一対の取付帯板部31，31は、起立片部32が第１柄部材11の先端面に当接するまで、シャンク部21と共に差し込まれる。 Then, the standing piece portions 32, 32 of the pair of L-shaped members 3, 3 are arranged so as to protrude in opposite directions, and the shank portion 21 is sandwiched between the pair of attachment band plate portions 31, 31, The one handle member 11 is inserted into the insertion recess 11 b provided from the front end surface.
The pair of attachment band plate portions 31, 31 are inserted together with the shank portion 21 until the upright piece portion 32 comes into contact with the distal end surface of the first handle member 11.

そして、第１柄部材11の先端部11ａを貫通する２つの取着用孔11ｇ，11ｇと、取付帯板部31の２つの貫通孔31ｇ，31ｇ及びシャンク部21の２つの貫孔21ｇ，21ｇが夫々連通し、ボルト部材からなる軸状部材81を串差し状に挿通させ、ナット部材82を螺着し、取付帯板部31をシャンク部21に圧接させて、取着している。 And two attachment holes 11g and 11g which penetrate the front-end | tip part 11a of the 1st handle member 11, two through-holes 31g and 31g of the attachment band board part 31, and two through-holes 21g and 21g of the shank part 21 are provided. The shaft member 81 made of a bolt member is inserted in a skewered manner, the nut member 82 is screwed, and the attachment band plate portion 31 is brought into pressure contact with the shank portion 21 for attachment.

なお、図１と図３及び図４に於て、第１柄部材11の差込凹部11ｂを矩形状孔部とした例を図示しているが、図５に示す他例のように、差込凹部11ｂを、シャンク部21の幅方向Ｗに開口するスリット状溝部としても良い。また、第１柄部材11の先端部11ａは、図例のような差込凹部11ｂを有する中実棒状に限らず、パイプ部と、差込凹部11ｂを有すると共にそのパイプ部に内嵌される詰め部材と、から成るように構成しても良い。
また、起立片部32，32は、その先端部が、第１柄部材11の外周面11ｄよりもラジアル外方側に配設される形状であれば、図例のように、先端縁が円弧状の全体丸山型（舌型）に限らず、全体半円型や全体矩形型等自由である。 1, 3, and 4, an example in which the insertion recess 11 b of the first handle member 11 is a rectangular hole is illustrated. However, as in the other example shown in FIG. The recess 11b may be a slit-like groove that opens in the width direction W of the shank 21. Further, the tip end portion 11a of the first handle member 11 is not limited to a solid rod shape having the insertion recess 11b as shown in the figure, and has a pipe portion and the insertion recess 11b and is fitted into the pipe portion. You may comprise so that it may consist of a stuffing member.
Further, if the standing pieces 32 and 32 have a shape in which the tip ends are arranged radially outward from the outer peripheral surface 11d of the first handle member 11, the tip edges are circular as shown in the figure. It is not limited to the arc-shaped whole round mountain type (tongue type), but may be a whole semicircular type or a whole rectangular type.

上述のように、第１柄部材11に鎌本体２と共に一対のＬ字状部材３，３を取着して、第１柄部材11の先端部11ａ（先端）に設けた一対の起立片部32，32をもって、図６に示すように柄本体１を伸縮させる際に第１柄部材11を握った手指が矢印Ｙ方向に滑って鎌本体２の刃部22に接触するのを防止する鍔部５を、形成している。
鍔部５は、第１柄部材11の軸心Ｌに直交状の平面と平行に配設される。そして、第１柄部材11の外周面11ｄよりもラジアル外方側に配設される当り部51を有している。言い換えると、第１柄部材11の軸心Ｌ方向からみて外周面11ｄから突出状の当り部51を有している（図３及び図５参照）。 As described above, the pair of upright pieces provided at the tip end portion 11a (tip end) of the first handle member 11 by attaching the pair of L-shaped members 3 and 3 together with the sickle body 2 to the first handle member 11 With 32 and 32, when the handle body 1 is expanded and contracted as shown in FIG. 6, the finger that grips the first handle member 11 is prevented from slipping in the arrow Y direction and coming into contact with the blade portion 22 of the sickle body 2. Part 5 is formed.
The collar portion 5 is disposed in parallel to a plane orthogonal to the axis L of the first handle member 11. And it has the contact part 51 arrange | positioned rather than the outer peripheral surface 11d of the 1st handle member 11 in the radial outward side. In other words, it has the contact | abutting part 51 which protruded from the outer peripheral surface 11d seeing from the axial center L direction of the 1st handle member 11 (refer FIG.3 and FIG.5).

例えば、第１柄部材11を把持した手指が、柄本体１を伸長させるため、第１柄部材11を第２柄部材12から引き出す力作業を行った際、或いは、短縮させるために、握力を弱めて、第１柄部材11を送りながら第２柄部材12に挿入する作業を行った際に、手指が滑って、刃部22と手指が相互に接近しようとしても、手指と鍔部５の当り部51が接触して、第１柄本体11の先端面よりも刃部22側へ手指が移動するのを阻止する。
従って、刃部22によるケガに限らず、鎌本体２において第１柄部材11から突出している全ての部位によるケガも防止できる。 For example, when a finger holding the first handle member 11 extends the handle body 1 to perform a force operation to pull out the first handle member 11 from the second handle member 12, or to shorten it, the grip force is increased. When the operation of inserting the first handle member 11 into the second handle member 12 while performing weakening is performed, even if the fingers slip and the blade portion 22 and the fingers approach each other, the fingers and the heel portion 5 The contact portion 51 comes into contact and prevents the fingers from moving from the distal end surface of the first handle body 11 to the blade portion 22 side.
Therefore, not only the injury by the blade part 22, but also the injury caused by all the portions protruding from the first handle member 11 in the sickle body 2 can be prevented.

また、起立片部32は、シャンク部21や取付帯板部31と同じ幅寸法をもってシャンク部21や取付帯板部31の厚み方向Ｔに突出する形状、言い換えると、シャンク部21や取付帯板部31の側縁よりも幅方向外方側に配設される部位を省略した形状とすることで、使用者側の手前側に引き寄せて草を切断する作業の際に鍔部５が邪魔とならない。つまり、平面視Ｌ字状やＴ字状の鎌本体２に好適である。 Further, the standing piece 32 has the same width dimension as the shank part 21 and the attachment band plate part 31 and projects in the thickness direction T of the shank part 21 and the attachment band plate part 31, in other words, the shank part 21 and the attachment band plate. By adopting a shape that omits the portion disposed on the outer side in the width direction from the side edge of the portion 31, the hook portion 5 is obstructed during the work of drawing the grass closer to the user side and cutting the grass. Don't be. That is, it is suitable for the sickle body 2 having an L shape or a T shape in plan view.

なお、本考案は設計変更可能であって、軸状部材81をリベット部材とし第１柄部材11を挿通した端部を圧潰して、リベット止めにて鎌本体２とＬ字状部材３を取着しても良い。また、軸状部材81をピン部材として圧入で取着しても良い。第１柄部材11の取着用孔11ｇ，11ｇと、取付帯片部31の貫通孔31ｇ，31ｇと、シャンク部21の貫孔21ｇ，21ｇの数は自由である。なお、鎌本体２の形状は、図例に限らず自由である。また、Ｌ字状部材３は、樹脂成形品や金属プレス加工品、木工品等、手指が接触した際に変形や損傷しない強度を有していれば、材質や製造手段は自由である。また、起立片部32を、シャンク部21や取付帯板部31の側縁部よりも幅広に形成するも好ましい（図示省略）。 The design of the present invention can be changed. The shaft member 81 is used as a rivet member, the end portion through which the first handle member 11 is inserted is crushed, and the sickle body 2 and the L-shaped member 3 are removed by riveting. You may wear it. Further, the shaft-like member 81 may be attached by press-fitting as a pin member. The number of the mounting holes 11g, 11g of the first handle member 11, the through holes 31g, 31g of the attachment band piece portion 31, and the through holes 21g, 21g of the shank portion 21 are arbitrary. In addition, the shape of the sickle main body 2 is not restricted to the example of a figure, but is free. The L-shaped member 3 can be made of any material or manufacturing means as long as the L-shaped member 3 has a strength such as a resin molded product, a metal press-processed product, a woodwork product, and the like that does not deform or damage when touched by fingers. It is also preferable that the standing piece 32 is formed wider than the side edge of the shank part 21 or the attachment band plate part 31 (not shown).
