いるものである。[Detailed description of the invention] This invention uses a vibration-absorbing coil spring to absorb the vibrations of the handle caused by the chainsaw machine that generates vibrations, thereby preventing the vibrations from being transmitted to the cylindrical grip body superimposed on the handle. The handle, which is vibrated by the chainsaw body that generates vibration, is overlapped and held by a cylindrical grip, and the handle and the cylindrical grip are overlapped and held. A vibration-absorbing coil spring is interposed in the gap between the body and the body, consisting of a small-diameter inner ring part and a large-diameter outer ring part with different diameters connected in series using an inclined spiral coil spring. The inner peripheral surface of the small-diameter inner ring portion of the inclined vibration-absorbing coil spring is wound and fitted onto the outer peripheral surface of the handle, and the outer edge of the small-diameter inner ring portion is wrapped around the outer peripheral surface of the handle. The outer circumferential surface of the large diameter outer ring portion is wound and fixed to the inner circumferential surface of the cylindrical grip body by being connected and fixed so that it does not move by a ring-shaped stopper attached to the surface. As an embodiment thereof, an appropriate plurality of the cylindrical gripping bodies 3 are attached to the handle 2.
而して、前記大径外輪部の外周面と筒状握持体の内周面
との定着は、半田付け等して適宜行なわれる。The outer circumferential surface of the large-diameter outer ring portion and the inner circumferential surface of the cylindrical gripping body are appropriately fixed by soldering or the like.
チェーンソーにおける振動を発生する振動機体によって
起振されるハンドルは従来一般に筒状握持体によって握
持される。In a chainsaw, a handle that is vibrated by a vibrating body that generates vibrations is generally gripped by a cylindrical grip body.
その為に、振動機体によって起振されたハンドルの振動
は、そのまま握持体に伝達され、これを握持する身体が
はげしく振動されて支障を来す場合が′多い。Therefore, the vibration of the handle generated by the vibrating body is directly transmitted to the gripping body, and the body that grips it is often vibrated violently, causing trouble.
このような握持体の振動を防ぐ為の振動吸収ハンドルと
して、振動体の固定ハンドル軸に握り筒を外嵌し、その
握り筒の両端部に突部が三方に向けてハンドルケースを

から各突部の外端を、常時外方に押圧する圧縮弾性体と
、各突部の外端を常時固定ハンドル軸に向けて引圧する
引張弾性体とを組込ませた構造のものが、従来公知に属
している。As a vibration-absorbing handle to prevent such vibration of the gripping body, a gripping tube is fitted onto the fixed handle shaft of the vibrating body, and a handle case is provided at both ends of the gripping tube with protrusions protruding in three directions. Inside the handle case, there is a compressive elastic body that constantly presses the outer end of each protrusion outward from the fixed handle shaft, and a tensile elastic body that constantly pulls the outer end of each protrusion toward the fixed handle shaft. Structures that incorporate the body are conventionally known.
この従来構造では、固定ハンドルの振動は、その固定ハ
ンドルの軸線方向に対して直交した弾性体によって吸収
されるのみであるため、固定ハンドルの軸線方向の振動
は依然として握り筒に伝達されることになり、その振動
を充分に吸収することができない欠点がある。In this conventional structure, vibrations of the fixed handle are only absorbed by the elastic body perpendicular to the axial direction of the fixed handle, so vibrations in the axial direction of the fixed handle are still transmitted to the grip barrel. This has the disadvantage that the vibration cannot be absorbed sufficiently.
これに対して、この出願の考案は、この従来構造の欠点
を除去して、振動を発生するチェーンソー機体によって

振動伝達を防止させたものである。In contrast, the invention of this application eliminates the drawbacks of this conventional structure, absorbs the vibrations of the handle generated by the vibration-generating chainsaw body with a vibration-absorbing coil spring, and uses a cylinder superimposed on the handle. This prevents vibration from being transmitted to the gripping body.
この出願の考案によれば、前記チェーンソー機体によっ

されないことになる。According to the invention of this application, the vibrations of the handle generated by the chainsaw body are absorbed by an inclined vibration-absorbing coil spring whose outer edges are connected and fixed by a ring-shaped stopper attached to the outer circumferential surface of the handle. The energy is transmitted from the small-diameter inner ring to the spiral coil spring, but since the absorbing coil spring has an inclined shape that expands from the small-diameter inner ring to the large-diameter outer ring, the spiral coil spring The vibration is gradually attenuated while being transmitted to the vibration-absorbing coil spring, and almost no vibration is transmitted to the large-diameter outer ring portion of the vibration-absorbing coil spring.
従って、吸振コイルスプリングの大径外輪部の外周面に
嵌合した筒状握持体には、前記振動は殆んど伝達されな

されることになり、その為、握持体を握持する作業者の

る。Therefore, almost no vibration is transmitted to the cylindrical grip body fitted to the outer peripheral surface of the large-diameter outer ring portion of the vibration-absorbing coil spring, so transmission of vibration to the cylindrical grip body is sufficiently prevented. Therefore, vibration transmission to the body of the worker who grips the grip body is prevented, and a vibration-proof chainsaw that does not cause any harm to the body of the worker is obtained, which is extremely useful. be.
