Description

本考案は、ケーブル、巻き爪、硬い爪などを切断する手工具に関する。   TECHNICAL FIELD The present invention relates to a hand tool for cutting a cable, a claw, a hard claw, or the like.

ケーブル、巻き爪、硬い爪などを切断する手工具が提案されている（特許文献１参照）。この手工具の一例として、一対の把持部と、一対の把持部に連動して軸部を中心として揺動する一対の挟持部とを備えるものがある。図３に示すように、軸部２４より先端側の一対の挟持部２６は、それぞれ刃部２６Ａを有する。各刃部２６Ａは、挟持部２６の互いに対向する側とは反対側の端面より互いに対向する側に向かって徐々に厚みが薄く形成されている。   A hand tool for cutting a cable, a winding nail, a hard nail, etc. has been proposed (see Patent Document 1). An example of this hand tool includes a pair of gripping portions and a pair of gripping portions that interlock with the pair of gripping portions and swing around a shaft portion. As shown in FIG. 3, the pair of holding portions 26 on the tip side of the shaft portion 24 each have a blade portion 26A.

ところで、刃部２６Ａの幅が広いと細く奥まったところにあるものを切断できないため、挟持部２６の幅が狭い手工具の要請がある。しかし、単に刃部２６Ａの幅Ｗを細くすると、刃部２６Ａが互いに対向する側に向かって徐々に厚みを薄く形成する構成であるため、挟持部２６の強度が不足するという問題がある。   By the way, if the width of the blade portion 26A is wide, it is not possible to cut a thin, deep-cut object, so there is a demand for a hand tool with a narrow width of the holding portion 26. However, if the width W of the blade portion 26A is simply reduced, the blade portion 26A has a structure in which the thickness is gradually reduced toward the sides facing each other, so that there is a problem that the strength of the holding portion 26 is insufficient.

そこで、本考案は、このような従来の手工具における問題点に鑑みてなされたものであり、挟持部の幅を狭く形成しても挟持部の強度が高い手工具を提供することを目的とする。   Therefore, the present invention has been made in view of the problems in the conventional hand tools, and an object thereof is to provide a hand tool having a high gripping portion strength even when the width of the gripping portion is narrow.

一対の挟持部６は、被切断物（図示せず）を切断する部位である。一対の挟持部６は、互いに対向し合う側には軸部４の延在方向Ｊに凹む薄肉部１０をそれぞれ有し、互いに対向し合う側とは反対側には薄肉部１０よりも肉厚の背側補強部１１を有する。薄肉部１０は、軸部４の側の起点ａから先端ｂにまで延びる刃部１０Ａを形成している。刃部１０Ａは、互いに対向し合う先端が刃先であり、下記する第１補強部１２との境界位置が起点ａとされ、従来例よりも起点ａが挟持部６の先端側に位置している。   The pair of sandwiching portions 6 are portions for cutting an object to be cut (not shown). The pair of sandwiching portions 6 each have a thin portion 10 that is recessed in the extending direction J of the shaft portion 4 on the side facing each other, and are thicker than the thin portion 10 on the side opposite to each other. Has a back side reinforcing portion 11. The thin portion 10 forms a blade portion 10A extending from a starting point a on the side of the shaft portion 4 to a tip b. In the blade portion 10A, the tips facing each other are the blade tips, and the boundary position with the first reinforcing portion 12 described below is the starting point a, and the starting point a is located closer to the leading end side of the sandwiching portion 6 than in the conventional example. ..

一対の挟持部６は、薄肉部１０の起点ａと軸部４との間に延在する部位を有し、薄肉部１０の起点ａの側である第１延在範囲Ｅ１には、背側補強部１１の最大厚みｔ１以上の所定厚みｔ２へと徐々に厚みが増加する第１補強部１２が設けられている。軸部４の側である第２延在範囲Ｅ２には、所定厚みｔ２を有する第２補強部１３が設けられている。   The pair of sandwiching portions 6 has a portion extending between the starting point a of the thin portion 10 and the shaft portion 4, and the back side is included in the first extending range E1 on the side of the starting point a of the thin portion 10. A first reinforcing portion 12 is provided whose thickness gradually increases to a predetermined thickness t2 that is equal to or larger than the maximum thickness t1 of the reinforcing portion 11. A second reinforcing portion 13 having a predetermined thickness t2 is provided in the second extending range E2 on the side of the shaft portion 4.

図２（ｂ）、図１（ｂ）を参照する。一対の挟持部６は、軸部４の延在方向Ｊの平面視で、Ｋ軸を対象として全体二等辺三角形に形成されている。   Please refer to FIG. 2B and FIG. The pair of holding portions 6 are formed in a generally isosceles triangle with respect to the K axis in a plan view in the extending direction J of the shaft portion 4.

図２（ｃ）、図１（ｂ）を参照する。各挟持部６は、軸部４の延在方向Ｊに対して直角方向の側面視で、先端に向かって徐々に細く形成されている。   Please refer to FIG. 2 (c) and FIG. 1 (b). Each sandwiching portion 6 is formed so as to be gradually narrowed toward the tip end in a side view perpendicular to the extending direction J of the shaft portion 4.

第１補強部１２の上面は、軸部４の延在方向Ｊに対して直角方向の側面視で、アール形状に形成されている（図２（ｃ）、図１（ｂ）参照）。アール形状の半径は、挟持部６の上面全体をアール形状にした場合におけるアール形状の半径よりも小さい。   The upper surface of the first reinforcing portion 12 is formed in a rounded shape in a side view perpendicular to the extending direction J of the shaft portion 4 (see FIGS. 2C and 1B). The radius of the rounded shape is smaller than the radius of the rounded shape when the entire upper surface of the holding portion 6 is rounded.

以上説明したように、本実施形態に係る手工具１は、一対の把持部５と、一対の把持部５に連動して軸部４を中心として揺動する一対の挟持部６とを備えており、一対の挟持部６は、互いに対向し合う側には軸部４の延在方向Ｊに凹む薄肉部１０をそれぞれ有し、互いに対向し合う側とは反対側には薄肉部１０よりも肉厚の背側補強部１１を有し、薄肉部１０は、軸部４の側の起点ａから先端ｂまで延びる刃部１０Ａを形成し、薄肉部１０の起点ａと軸部４との間に延在し、薄肉部１０の起点ａの側である第１延在範囲Ｅ１に設けられ、背側補強部１１の最大厚みｔ１以上の所定厚みｔ２へと徐々に厚みが増加する第１補強部１２と、軸部４の側である第２延在範囲Ｅ２に設けられ、所定厚みｔ２を有する第２補強部１３とを有する。   As described above, the hand tool 1 according to the present embodiment includes the pair of grips 5 and the pair of grips 6 that swings around the shaft 4 in association with the pair of grips 5. The pair of sandwiching portions 6 each have a thin portion 10 recessed in the extending direction J of the shaft portion 4 on the side facing each other, and a thin portion 10 on the opposite side to the side facing each other than the thin portion 10. The thin-walled portion 10 has a thick back reinforcing portion 11 and forms a blade portion 10A extending from a starting point a on the side of the shaft portion 4 to a tip b, and between the starting point a of the thin-walled portion 10 and the shaft portion 4. Is provided in a first extending range E1 that is on the side of the starting point a of the thin portion 10 and gradually increases in thickness to a predetermined thickness t2 that is greater than or equal to the maximum thickness t1 of the back side reinforcing portion 11. It has a portion 12 and a second reinforcing portion 13 provided in the second extending range E2 on the side of the shaft portion 4 and having a predetermined thickness t2.

したがって、一対の刃部１０Ａは、その背側が背側補強部１１で補強され、一対の刃部１０Ａと軸部４の間が第１補強部１２及び第２補強部１３で補強されているため、実施形態のように挟持部６の幅を細く形成しても強度が高い手工具１を提供できる。   Therefore, the back side of the pair of blade portions 10A is reinforced by the back side reinforcing portion 11, and the portion between the pair of blade portions 10A and the shaft portion 4 is reinforced by the first reinforcing portion 12 and the second reinforcing portion 13. The hand tool 1 having high strength can be provided even when the width of the holding portion 6 is narrowed as in the embodiment.

一対の挟持部６は、軸部４の延在方向Ｊの平面視で、全体二等辺三角形に形成されている。したがって、一対の挟持部６を幅の狭い隙間にも容易に挿入でき、隙間の奥まったところに位置する被切断物（図示せず）を切断できる。   The pair of holding portions 6 are formed into an isosceles triangle as a whole in a plan view in the extending direction J of the shaft portion 4. Therefore, the pair of sandwiching portions 6 can be easily inserted into a narrow gap, and an object to be cut (not shown) located deep in the gap can be cut.

各挟持部６は、軸部４の延在方向Ｊに対して直角方向の側面視で、先端に向かって徐々に細く形成されている。したがって、一対の挟持部６を高さの低い隙間にも容易に挿入でき、隙間の奥まったところに位置する被切断物（図示せず）を切断できる。   Each sandwiching portion 6 is formed so as to be gradually narrowed toward the tip end in a side view perpendicular to the extending direction J of the shaft portion 4. Therefore, the pair of holding portions 6 can be easily inserted into a gap having a low height, and an object to be cut (not shown) located in the deep part of the gap can be cut.

第１補強部１２の上面は、軸部４の延在方向Ｊに対して直角方向の側面視で、アール形状に形成されている。したがって、一対の刃部１０Ａの長さよりも深い隙間にも極力スムーズに挿入でき、使い勝手が良い。
アール形状の半径は、挟持部６の上面全体をアール形状にした場合におけるアール形状の半径よりも小さい。これにより、第１補強部１２よりも強度アップに寄与する第２補強部１３の寸法を極力大きく取ることができるため、一対の挟持部６の強度向上を図ることができる。 The upper surface of the first reinforcing portion 12 is formed in a rounded shape in a side view perpendicular to the extending direction J of the shaft portion 4. Therefore, it can be inserted into a gap deeper than the length of the pair of blades 10A as smoothly as possible, which is convenient.
The radius of the rounded shape is smaller than the radius of the rounded shape when the entire upper surface of the holding portion 6 is rounded. As a result, the size of the second reinforcing portion 13 that contributes to an increase in the strength of the first reinforcing portion 12 can be made as large as possible, so that the strength of the pair of sandwiching portions 6 can be improved.

以上、本実施形態を説明したが、本実施形態はこれらに限定されるものではなく、本実施形態の要旨の範囲内で種々の変更が可能である。   Although the present embodiment has been described above, the present embodiment is not limited to these, and various modifications can be made within the scope of the gist of the present embodiment.
