Conventionally, as a spring device for clamping tools,
As in Publication No. 542, a coil spring part is formed by winding the center part of a single wire rod, and a wound coil tube is provided at the tips of both left and right rod parts to fit into the handle of any tool. A spring device for a tool has already been proposed in which a wound coil cylinder is fitted onto a handle of a tool and a spring body is installed between the handles.
しかし、このような構造の挾着工具のバネ装置
は、内周径が決まつている為左右のハンドルの途
中に巻回コイル筒を被嵌して左右のハンドル間に
バネ本体を架設するタイプの為バネ本体が邪魔に
なる欠点が生ずる。 However, since the spring device of a clamping tool with this structure has a fixed inner diameter, it is a type in which a wound coil tube is fitted in the middle of the left and right handles, and the spring body is installed between the left and right handles. This results in the disadvantage that the spring body gets in the way.
而かもハンドルの末端から巻回コイル筒を嵌挿
する際、ハンドルが太いと装着不能となり、また
所望の位置まで嵌挿出来なかつたりする欠点も生
ずる。 Moreover, when inserting the wound coil tube from the end of the handle, if the handle is too thick, it becomes impossible to attach the coil tube, and there is also the disadvantage that it cannot be inserted to the desired position.
本考案はこれらの欠点を解決したもので、添付
図面を参照にその構成を詳述すると次の通りであ
る。
The present invention solves these drawbacks, and its structure will be detailed as follows with reference to the accompanying drawings.

る。 A coil spring part 1 is formed by winding the center part of a single wire once or twice, and the end of a spring rod 2 that protrudes from the coil spring part 1 in a V-shape is formed into a U-shape in the coil plane of the coil spring part 1. The upper clamping part 3 is formed by bending it inward in a shape,
Further, the U-shaped end of the upper clamping part 3 is bent downwardly and outward again in a U-shape in a vertical plane perpendicular to the coil plane to form a lower clamping part 4, and the spring body The upper clamping part 3 consisting of two lines a and the lower clamping part 4 consisting of one line are pressed from the inside to the outside against the shoulder 7 near the pivot shaft 6 of the handle 5 of the tool body b. This is characterized in that the spring body a is attached in a resilient state between the left and right handle shoulders by being removably fitted.
本案品の線材は弾性に富む軟鋼線を使用すれば
良い。
As the wire for this product, a mild steel wire with high elasticity may be used.
図面のコイルバネ部1は線材を円筒丸棒に巻き
付けて所定大に折曲せしめれば良い。 The coil spring portion 1 shown in the drawings may be formed by winding a wire around a cylindrical round bar and bending it to a predetermined size.
上側挾着部3はU字状にベンチ等で折曲せしめ
れば良い。 The upper clamping portion 3 may be bent into a U-shape on a bench or the like.
下側挾着部4は挾着工具のハンドル5の枢着軸
6寄りの肩部7の厚さにあわせてペンチ等で折曲
せしめれば良い。 The lower clamping portion 4 may be bent using pliers or the like to match the thickness of the shoulder portion 7 of the handle 5 of the clamping tool near the pivot shaft 6.
挾着工具は連続作業を行う場合にはバネの復帰
力が働いた方が能率的に挾着作業が行なわれる
が、模型作り、装飾具作り等の細く、精度の高い
作業を行う場合には、逆にバネの復帰力が働かな
い方が良い。
If the clamping tool is used for continuous work, the clamping work will be done more efficiently if the return force of the spring works, but if the clamping tool is used for thin, highly precise work such as making models or decorative tools, it will be more efficient. On the contrary, it is better if the spring's return force does not work.
本考案は、この点を考慮してバネ本体を挾着工
具本体に対して着脱自在に設けたから連続作業を
必要とする時には第1図に示すようにバネ本体を
取り付けて使用すれば良く、逆に細く、精度の高
い作業を行う時には第2図に示すようにバネ本体
を取り外して行えば良く、挾着工具の使用用途に
応じてバネ本体を取り外したり、取り付けたりす
る便利な挾着工具になる。 In consideration of this point, the present invention has provided the spring body to be detachable from the clamping tool body, so when continuous work is required, the spring body can be attached and used as shown in Figure 1, and vice versa. When performing narrow, high-precision work, the spring body can be removed as shown in Figure 2, making it a convenient clamping tool that can be used to remove or attach the spring body depending on the intended use of the clamping tool. Become.
このバネ本体の取り付けも上側挾着部と下側挾
着部とを挾着工具本体のハンドルの枢着軸寄りの
肩部に内側から外側に向けて圧入挾着するだけで
良いのであるから極めて簡単であり、また取り外
しも上側挾着部と下側挾着部とを肩部より引き抜
くだけで良く、取り付け同様に簡単である。 The installation of the spring body is extremely easy as all you have to do is press-fit the upper clamping part and the lower clamping part to the shoulder part of the clamping tool body near the pivot axis of the handle from the inside to the outside. It is easy to remove and can be removed simply by pulling out the upper and lower clamping parts from the shoulder, making it as easy to install.
このバネ本体は上側挾着部と下側挾着部で肩部
を上下面から挾着している上に、肩部基部の膨出
部に係止しているためずり動することなく、所定
の位置に取り付けられることになる。 This spring body not only clamps the shoulder from the upper and lower surfaces with the upper and lower clamping parts, but also locks into the bulge at the base of the shoulder, so it does not slide and remains in place. It will be installed in the position.
この際、バネ本体の上側挾着部は2本線より成
つているためハンドルの肩部に嵌着したとき2ケ
所で支持されることになり、それだけバネ本体が
ぐらつかないことになり、その上上側挾着部に対
して下側挾着部が外側向きU字状に折曲されてい
るからバネ本体は工具本体のハンドル肩部間に安
定良く装着され、その着脱は在来の巻回コイル筒
を形成してハンドルに被嵌るタイプの装着法に比
して極めて着脱が容易となり、且つハンドルを外
側に弾圧する状態に付設されるから極めて使い易
い挾着工具のバネ装置となる。 At this time, since the upper clamping part of the spring body is made of two wires, when it is fitted to the shoulder of the handle, it will be supported in two places, which will prevent the spring body from wobbling, and the upper Since the lower clamping part is bent outward in a U-shape with respect to the clamping part, the spring body can be stably attached between the handle shoulders of the tool body, and its attachment and detachment can be done using a conventional wound coil tube. The spring device of the clamping tool is extremely easy to use because it is attached in a state where the handle is pressed outward, and the spring device is extremely easy to attach and detach compared to a type of attachment method in which a handle is formed and fitted over the handle.
また、本案品は、構造も簡単であるから製作も
容易となり、量産可能にして、それだけ製品を安
価に提供する等の秀れた実用上の効果を有するも
のである。 In addition, the proposed product has a simple structure, which makes it easy to manufacture, and it has excellent practical effects such as mass production, which allows the product to be provided at a correspondingly low cost.
