【考案の詳細な説明】 本考案は家畜（例えば牛・馬等の大動物）の蹄を削蹄す
る削蹄用剪鉗に関し、その目的とする処は人畜共に危険
なく、片手で操作使用出来き小さな力で容易に削蹄する
ことが出来る削蹄用剪鉗を提供せんとするものである。[Detailed description of the invention] This invention relates to a hoof-shaving shear for cutting the hooves of livestock (for example, large animals such as cows and horses). To provide a hoof cutting shear that can easily cut a hoof with a small amount of force.

従来家畜の削蹄にはカマ、ナタ或いは両手で使用する鋏
状の削蹄器を用いていたがカマ、ナタを用いての削蹄作
業は、熟練を必要とし素人には無理であり、昔たその作
業には危険が伴なった。Traditionally, a sickle, a machete, or a scissor-shaped hoof trimmer used with both hands was used to trim the hooves of livestock. The work involved danger.

また削蹄器では、両手を使用しなげればならず、小１か
な削蹄作業には不向きであった。In addition, the hoof trimmer requires the use of both hands, making it unsuitable for cutting the hoofs of elementary school students.

而して本考案はこのような現状に鑑み術者及び家畜に危
険がなく、片手で簡単に使用出来、しかも小さな力で削
蹄が行なえる削蹄用剪鉗を提供するにある。In view of the current situation, the present invention provides a hoof trimming shear that poses no danger to the operator or livestock, can be easily used with one hand, and can perform hoof trimming with a small amount of force.

以下本考案実施の一例を図面に基づいて説明する。An example of implementing the present invention will be described below based on the drawings.

図中ａは削蹄杆であり、上方に彎曲部１を形成し彎曲部
１に連続して平板状の連結部２を形成すると共に、連結
部２下方に握柄部３を備える。In the figure, a shows a hoof cutting rod, which has a curved part 1 formed above, a flat connecting part 2 continuous to the curved part 1, and a handle part 3 below the connecting part 2.

そして連結部２に削蹄片すを軸４で開閉自在に枢着する
。A hoof trimmer is pivotally attached to the connecting part 2 by a shaft 4 so as to be openable and closable.

削蹄片すには、削蹄杆ａの彎曲部１と同様の彎曲部１′
及び連結部２′を形成し、その連結部２′が削蹄杆ａの
連結部２に枢着されている。To cut the hoof, use a curved part 1' similar to the curved part 1 of the hoof trimmer a.
and a connecting portion 2', which is pivotally connected to the connecting portion 2 of the hoof cutting rod a.

削蹄杆ａと削蹄片すの夫々の彎曲部１，１′は互に内方
に彎曲して先端部が当接するようにすると共に、先端部
に嘴状の刃部５，５′を形成し、蹄を削切し得るように
する。The curved parts 1 and 1' of the hoof cutting rod a and the hoof cutting piece S are each curved inward so that their tips abut, and beak-shaped blade parts 5 and 5' are provided at the tips. Shape and allow the hoof to be cut.

削蹄杆ａの連結部２には、握柄部Ｃを支承する支承軸部
６が軸４の下方に位置して突設され、削蹄片すの連結部
２′には握柄部Ｃと連係する連係軸部７が突設しである
。A supporting shaft portion 6 for supporting a handle C is located below the shaft 4 and protrudes from the connecting portion 2 of the hoof shaving rod a, and a supporting shaft portion 6 that supports the handle C is protruded from the connecting portion 2 of the hoof shaving rod a. A linking shaft portion 7 that is linked to is provided in a protruding manner.

握柄部Ｃは、削蹄杆ａの握柄部３と対向するように設け
られており、その上部に削蹄杆ａの支承軸部６に嵌合す
る穴８が開穿され、そこを中心として握柄部Ｃと削蹄杆
ａは開閉する。The grip portion C is provided to face the grip portion 3 of the hoof cutting rod a, and a hole 8 is drilled in its upper portion to fit into the support shaft portion 6 of the hoof cutting rod a. The grip handle C and the hoof cutting rod a open and close as the center.

又握柄部Ｃにはガイド溝９を開穿し、ガイド溝９を削蹄
片すに突設した連係軸部７と係合させ、握柄部Ｃの開閉
に伴なって削蹄片すが軸４を中心として回動し、先端の
刃部５′が削蹄杆ａの刃部５に対して開閉動するように
する。In addition, a guide groove 9 is bored in the grip handle C, and the guide groove 9 is engaged with a linking shaft 7 protruding from the hoof cutter, so that the hoof cutter is opened and closed as the grip handle C is opened and closed. rotates about the shaft 4, and the blade portion 5' at the tip opens and closes relative to the blade portion 5 of the hoof cutting rod a.

また握柄部Ｃにはストッパ一部１０が形成されており、
刃部５，５′を閉じた状態でストッパ一部１０が削蹄杆
ａの握柄部３に当接し、刃部５゜５′に必要以上の力が
加わり、刃部５，５′が破損するのを防止している。In addition, a stopper portion 10 is formed on the grip handle C.
With the blade parts 5, 5' closed, the stopper part 10 comes into contact with the handle part 3 of the hoof cutting rod a, and more force than necessary is applied to the blade part 5, 5', causing the blade part 5, 5' to Prevents damage.

さらに握柄部Ｃ及び削蹄杆ａの握柄部３とに渉ってコイ
ルバネ１１を架設し刃部５，５′を常に開く方向に付勢
している。Further, a coil spring 11 is installed across the grip portion C and the grip portion 3 of the hoof cutting rod a to constantly bias the blade portions 5, 5' in the open direction.

筐た削蹄杆ａの握柄部３下部には掛止片１２と板バネ１
３よりなる掛止具１４を取付ける。A latch piece 12 and a leaf spring 1 are attached to the lower part of the handle part 3 of the housing hoof rod a.
Attach the hook 14 consisting of 3 pieces.

掛止片１２は、握柄部３下端にピンで枢着されて、千の
先端の鉤部が握柄部Ｃの下端に引っ掛るようにし、板バ
ネ１３の付勢により掛止状態が保持される。The latching piece 12 is pivotally attached to the lower end of the grip handle 3 with a pin so that the hook at the tip of the hook is hooked to the lower end of the grip handle C, and the latching state is maintained by the urging force of the leaf spring 13. be done.

次に削蹄動作について説明すると、掛止片１２の先端鉤
部を握柄部Ｃの下端部より外すとコイルバネ１１の弾発
力により、握柄部Ｃと削蹄杆ａが支承軸部６を中心とし
て外側方へ回動し、握柄部Ｃの開動は、ガイド溝９に連
係した連係軸部Ｉを介して削蹄片すに伝えられて、刃部
５，５′が外側方へ軸４を中心として開動して削蹄し得
る状態となる。Next, explaining the hoof trimming operation, when the distal end hook of the hooking piece 12 is removed from the lower end of the handle C, the elastic force of the coil spring 11 causes the handle C and the hoof cutter a to move onto the support shaft 6. The opening movement of the grip handle C is transmitted to the hoof cutting strip through the linking shaft I linked to the guide groove 9, and the blade parts 5 and 5' move outward. It opens around the shaft 4 and becomes ready for hoof trimming.

而して削蹄する時は、握柄部Ｃ及び握柄部３を片手で握
り、コイルバネ１１の弾発力に抗して閉動させると、握
柄部Ｃの閉動が削蹄片すに伝えられ刃部５，５′が閉鎖
し蹄を削切する。When trimming the hoof, grip the handle C and the handle 3 with one hand and close them against the elastic force of the coil spring 11.The closing movement of the handle C will cause the hoof trimming to take place. The blade portions 5, 5' close and cut the hoof.

この時削蹄片すの連係軸部７には握柄部Ｃに加えた力が
梃子の原理により倍加されて伝わるので、刃部５，５′
には大きな力が発生し、削蹄する時に要する力は小さく
てすむものである。At this time, the force applied to the handle C is doubled and transmitted to the linking shaft 7 of the hoof cutter due to the principle of leverage, so the blades 5, 5'
A large amount of force is generated, and the force required for hoof trimming is small.

本考案は叙上の如く構成したので削蹄に要する力が少な
くてすみ、しかも削蹄鎌のように熟練を必要としないた
め簡単に使用出来る。Since the present invention is constructed as described above, less force is required for hoof trimming, and unlike hoof trimming sickles, it does not require skill, so it is easy to use.

しかも片手で扱えるため小１かな作業にも適しており、
踏角が延長し、削蹄鎌では削切困難な場合、あるいは砂
、小石を噛んで刃とぼれのおそれがある場合に於いても
容易且つきれいに剪除することが出来る。Moreover, since it can be handled with one hand, it is suitable for small-scale work.
Even in cases where the tread angle is extended and it is difficult to cut with a hoof cutting sickle, or in cases where there is a risk of the blade slipping due to sand or pebbles being bitten, it can be easily and cleanly removed.

またコイルバネにより刃部は常に開く方向に付勢されて
いるので使用時に於いて蹄の削切の度にいちいち刃部を
手で開く必要がなく、握力をゆるめると自然に刃部が開
き使い勝手がよい。In addition, since the blade is always biased in the open direction by a coil spring, there is no need to open the blade by hand every time the hoof is cut, and when you loosen your grip, the blade opens naturally, making it easier to use. good.

また掛止具の掛げることにより刃部の閉鎖状態を保つこ
とができ、保管時に刃部で怪我をすることがない。Furthermore, by hanging the hook, the blade can be kept in a closed state, so that there is no chance of injury from the blade during storage.

依って所期の目的を達成し得る。Therefore, the intended purpose can be achieved.
