Description

本発明は、枝木を把持して切断する枝切り鋏に関するものである。 The present invention relates to a branch cutting rod that holds and cuts branch trees.

従来、実開平４−７４９３３号公報に示される枝切り鋏があったが、前記公報の図２に示すように、この鋏は、その湾曲凹刃板５の凹縁に板状のノコギリ刃状の凹凸８を形成し、この凹凸８により枝木を滑動させないように把持して、湾曲凸刃板２で切断するようにしていたが、片刃で切断するため把持した外径２センチメートル程度の枝木しか切断することができず、外径２センチメートル以上の枝木を把持した場合、切断が不可能であり、別のノコギリで切断していた。
そこで、本発明者は、切刃と、枝木を把持する受刃に上刃と溝刃を形成することにより、枝木を把持すると共に、切刃と受刃の両刃で切断して太い枝木でも切断することができる枝切り鋏を開発した。
実開平４−７４９３３号公報 Conventionally, there has been a branch cutting scissors disclosed in Japanese Utility Model Publication No. 4-74933, but as shown in FIG. 2 of the above publication, this scissors have a plate-shaped saw blade shape on the concave edge of the curved concave blade plate 5. Are formed so that the branch tree is not slid by the unevenness 8 and is cut by the curved convex blade plate 2. However, since the cutting is performed by the single blade, the gripped outer diameter is about 2 centimeters. Only a branch tree could be cut, and when a branch tree having an outer diameter of 2 centimeters or more was gripped, cutting was impossible and cutting was performed with another saw.
Therefore, the present inventor forms the upper blade and the groove blade on the cutting blade and the receiving blade for holding the branch tree, thereby gripping the branch tree and cutting the thick blade with both the cutting blade and the receiving blade. We have developed a branch cutter that can cut even wood.

本発明は、切刃と、受刃により、太い枝木でも滑らないように把持すると共に、切刃と受刃の両刃により太い枝木でも容易に切断することができる枝切り鋏を提供するものである。 The present invention provides a cutting blade and a branch cutting rod that can be gripped by a receiving blade so that even a thick branch tree does not slip, and can be easily cut even by a thick branch tree by both cutting blades and the receiving blade. It is.

本発明枝切り鋏は、上記課題を達成するため、図１乃至図５に示すように、切刃１０と受刃２０からなる枝切り鋏において、受刃２０に、複数個の上刃２１と、上刃２１と上刃２１の間の複数個の溝刃２２とを設け、上刃２１及び溝刃２２を切刃１０の内刃面１１に対し下向きに接するように形成したものである。
また、本発明枝切り鋏は、上記課題を達成するため、図６乃至図１０に示すように、切刃１０Ｂと受刃２０Ｂからなる枝切り鋏において、受刃２０Ｂに、複数個の上刃２１Ｂと、上刃２１Ｂと上刃２１Ｂの間の複数個の溝刃２２Ｂとを設け、上刃２１Ｂ及び溝刃２２Ｂを切刃１０Ｂの内刃面１１Ｂに対し上向きに接するように形成したものである。
本発明において、切刃１０又は１０Ｂは、通常、刃先が凸形に形成されているが、刃先が凸形でない場合も含まれ、また、高所枝切り鋏のように切刃１０又は１０Ｂの先端に枝掛けのフックを形成した鋏なども含まれる。
受刃２０又は２０Ｂは、通常、受台２０１又は２０１Ｂが凹形に形成されているが、受台２０１又は２０１Ｂが凹形でない場合も含まれる。
受刃２０又は２０Ｂには、上刃２１（２１（１）及び２１（２）も含まれる。）又は２１Ｂ（２１Ｂ（１）及び２１Ｂ（２）も含まれる。）と溝刃２２又は２２Ｂとを備えているが、いずれも切刃１０又は１０Ｂの内刃面１１又は１１Ｂに接して切断作用ができるようになっている。また、上刃２１同士又は上刃２１Ｂ同士、上刃２１又は２１Ｂと溝刃２２又は２２Ｂ、又は上刃２１又は２１Ｂと溝刃２２又は２２Ｂと上刃２１又は２１Ｂとで枝木を把持する把持作用ができるようになっている。
さらに、上刃２１又は２１Ｂ及び溝刃２２又は２２Ｂは、切刃１０又は１０Ｂの内刃面に対し、下向き又は上向きに接するように形成されて、下向きの場合は引き切り、又は、上向きの場合は押し切りが簡単にできるようにすると共に、いずれの場合も枝木切断の際の切断残滓の排除を容易にできるように形成されている。 In order to achieve the above object, the branch cutting rod of the present invention is a branch cutting rod made up of a cutting blade 10 and a receiving blade 20, as shown in FIGS. The upper blade 21 and a plurality of groove blades 22 between the upper blades 21 are provided, and the upper blade 21 and the groove blade 22 are formed so as to contact the inner blade surface 11 of the cutting blade 10 downward.
Further, in order to achieve the above-mentioned problem, the branch cutting rod of the present invention has a plurality of upper blades on the receiving blade 20B in the branch cutting rod made up of the cutting blade 10B and the receiving blade 20B, as shown in FIGS. 21B and a plurality of groove blades 22B between the upper blade 21B and the upper blade 21B are provided, and the upper blade 21B and the groove blade 22B are formed so as to contact the upper blade surface 11B of the cutting blade 10B upward. is there.
In the present invention, the cutting edge 10 or 10B is usually formed with a convex cutting edge, but includes a case where the cutting edge is not convex, and also includes a cutting edge 10 or 10B like a high-end branch cutting rod. Also included is a hook with a branch hook formed at the tip.
In the receiving blade 20 or 20B, the receiving table 201 or 201B is normally formed in a concave shape, but the case where the receiving table 201 or 201B is not in a concave shape is also included.
The receiving blade 20 or 20B includes an upper blade 21 (including 21 (1) and 21 (2)) or 21B (including 21B (1) and 21B (2)) and a groove blade 22 or 22B. In any case, the cutting edge 10 or 10B is in contact with the inner blade surface 11 or 11B so that the cutting action can be performed. Further, the upper blades 21 or the upper blades 21B, the upper blades 21 or 21B and the groove blades 22 or 22B, or the upper blades 21 or 21B, the groove blades 22 or 22B, and the upper blades 21 or 21B are gripped. It can be used.
Furthermore, the upper blade 21 or 21B and the groove blade 22 or 22B are formed so as to be in contact with the inner blade surface of the cutting blade 10 or 10B downward or upward. Is formed so that it can be easily cut, and in any case, it is easy to eliminate cutting residue when cutting a branch tree.

本発明によれば、従来の同種の鋏に比較して、太い枝木でも把持して、軽い力で容易に切断できることとなった。また、受刃に下向き又は上向きの方向性を与えて、引き切り又は押し切りが簡単にできるようにすると共に、切断の際の切断残滓の排除が容易になった。 According to the present invention, it is possible to grasp even a thick branch tree and to easily cut it with a light force, as compared with the same type of conventional scissors. In addition, the receiving blade is given a downward or upward directivity so that it can be easily cut or pushed, and the cutting residue at the time of cutting can be easily eliminated.

本発明は、太い枝木を滑動しないようには把持し、容易に切断できるように、受刃に新規性を加えた枝切り鋏を実現した。 The present invention has realized a branch cutting rod with novelty to the receiving blade so that a thick branch tree can be gripped without sliding and can be easily cut.

本発明の実施例１が図１乃至図５に示されている。
本発明の枝切り鋏は、凸刃状の切刃１０と、凹刃状の受刃２０と、握り３０及び４０と、戻りバネ５０とを備えている。
切刃１０は、図４及び図５のＡ−Ａ断面及びＢ−Ｂ断面に示すように、断面が鋭利な三角形状で、切刃面１１が形成されると共に、受刃２０の上刃２１及び溝刃２２に接している。
受刃２０は、切刃１０の内刃面１１に接する上刃２１と溝刃２とが交互に図１乃至図３に示すように、鋸歯状に切刃１０の切刃面１１に対しいづれも下向きに接している。
従って、使用する時は、握り３０及び４０を握って枝木を把持し、手前へ引くようにしながら握りしめれば、枝木が滑動することなく、切刃１０と受刃２０の両刃により切断することができる。 A first embodiment of the present invention is shown in FIGS.
The branch cutting rod of the present invention includes a convex blade-shaped cutting blade 10, a concave blade-shaped receiving blade 20, grips 30 and 40, and a return spring 50.
As shown in the AA cross section and the BB cross section of FIGS. 4 and 5, the cutting blade 10 has a triangular shape with a sharp cross section, a cutting blade surface 11 is formed, and the upper blade 21 of the receiving blade 20. And the groove blade 22.
In the receiving blade 20, the upper blade 21 and the groove blade 2 that are in contact with the inner blade surface 11 of the cutting blade 10 are alternately wound on the cutting blade surface 11 of the cutting blade 10 in a sawtooth shape as shown in FIGS. 1 to 3. Also touches downward.
Therefore, when used, if the grips 30 and 40 are gripped and the branches are gripped while being pulled toward the front, they are cut by both the cutting edges 10 and the receiving blades 20 without sliding. be able to.

本発明の実施例２が図６乃至図１０に示されている。
本発明の枝切り鋏は、凸刃状の切刃１０Ｂと、凹刃状の受刃２０Ｂと、握り３０Ｂ及び４０Ｂと、戻りバネ５０Ｂとを備えている。
切刃１０Ｂは、実施例１の切刃１０と同一であるので詳細説明は省略する。
受刃２０Ｂは、図９及び図１０のＣ−Ｃ断面及びＤ−Ｄ断面に示すように、切刃１０Ｂの内刃面１１Ｂに接する上刃２１Ｂと溝刃２２Ｂとが交互に図６乃至図８に示すように、鋸歯状に切刃１０Ｂの切刃面１１Ｂに対し、いづれも上向きに接している。
従って、使用するときは、握り３０Ｂ及び４０Ｂを握って枝木を把持し、前方へ押すようにしながら握りしめれば、枝木が滑動することなく、切刃１０Ｂと受刃２０Ｂの両刃により切断することができる。 A second embodiment of the present invention is shown in FIGS.
The branch cutting rod of the present invention includes a convex blade-shaped cutting blade 10B, a concave blade-shaped receiving blade 20B, grips 30B and 40B, and a return spring 50B.
Since the cutting blade 10B is the same as the cutting blade 10 of Example 1, detailed description is abbreviate | omitted.
In the receiving blade 20B, as shown in the CC cross section and the DD cross section of FIGS. 9 and 10, the upper blade 21B and the groove blade 22B in contact with the inner blade surface 11B of the cutting blade 10B are alternately shown in FIGS. As shown in FIG. 8, all are in contact with the cutting edge surface 11 B of the cutting edge 10 B in a sawtooth shape upward.
Therefore, when used, if the grips 30B and 40B are gripped and the branches are gripped while being pushed forward, the branches will be slid and cut by both the cutting blade 10B and the receiving blade 20B without sliding. be able to.

本発明は、片手握りの枝切り鋏のほか、高所用の枝切り鋏や両手握りの枝打ち鋏等にも使用することができ、広い範囲で利用することができる。 The present invention can be used not only for a hand-holding branch scissors, but also for a high place or a two-hand scissors scissors, and can be used in a wide range.
