Title (EN) CHAINSAW
(FR) SCIE À CHAÎNE
(JA) チェンソー
Abstract:
(EN) Provided is a chainsaw in which increasing the rotation angle of a brake handle during assembly of component parts around the brake handle facilitates assembling. A chainsaw having a brake mechanism for braking a saw chain via the operation of a brake handle 9, wherein the the body housing 2 side of the chainsaw is provided with: the brake handle 9, which actuates brakes (30, 40); a brake link mechanism (20, 24, 25) for actuating the brakes via operation of the brake handle 9; and a brake spring 33. A brake link cover 6 for covering the brake mechanism is mounted using screw bosses 52a-52d. A rotation angle limiting member 61 for limiting the rotation range of the brake handle 9 is provided on the brake link cover 6 side. Detaching the brake link cover 6 increases the rotation range of the brake handle 9.
(FR) L'invention concerne une scie à chaîne dans laquelle une augmentation de l'angle de rotation d'une poignée de frein, pendant le montage des composants autour de la poignée de frein, facilite l'assemblage. Une scie à chaîne ayant un mécanisme de freinage servant à freiner une chaîne par le biais de l'actionnement d'une poignée (9) de frein, le boîtier (2) de corps du côté de la scie à chaîne étant pourvu : de la poignée (9) de frein, qui actionne les freins (30, 40); d'un mécanisme (20, 24, 25) de timonerie de frein servant à actionner les freins par le biais d'un actionnement de la poignée (9) de frein; et d'un ressort (33) de frein. Un couvercle (6) de timonerie de frein servant à recouvrir le mécanisme de frein est monté à l'aide de bossages (52a-52d) pour vis. Un élément de limitation (61) de l'angle de rotation servant à limiter la plage de rotation de la poignée (9) de frein est conçu sur le côté couvercle (6) de timonerie de frein. Le détachement du couvercle (6) de timonerie de frein augmente la plage de rotation de la poignée (9) de frein.
(JA) ブレーキハンドル周りの要素部品の組立時に、ブレーキハンドルの回動角度を大きくすることにより、組立性を向上させたチェンソーを提供する。ブレーキハンドル9の操作によりソーチェンにブレーキをかけるブレーキ機構を有するチェンソーにおいて、本体ハウジング2側に、ブレーキ(30、40)を作動させるブレーキハンドル9と、ブレーキハンドル9の操作によりブレーキを作動させるブレーキリンク機構(20、24、25)と、ブレーキスプリング33が設けられる。ネジボス52a~52dを用いてブレーキ機構を覆うブレーキリンクカバー6が取り付けられるが、このブレーキリンクカバー6側にブレーキハンドル9の回動範囲を制限する回動角度規制部材61を設け、ブレーキリンクカバー6を取り外すとブレーキハンドル9の回動範囲を大きくできるようにした。
