Title (EN) STRUCTURE FOR PREVENTING FALLING OFF OF RIVING KNIFE FASTENER FOR ROTARY SAW
(FR) STRUCTURE POUR EMPÊCHER LA CHUTE D'UN ORGANE DE FIXATION DE COUTEAU SÉPARATEUR POUR SCIE ROTATIVE
(JA) 切断機における割り刃の固定具脱落防止構造
Abstract:
(EN) Problems have been experienced that falling off of a fastener that secures a riving knife, which is provided in alignment with a rotary blade to prevent the so called "kick back" of a work sawn by a table saw, often occurs due to over loosening when adjusting the position of the riving knife thus leading to a lower operability. The invention is intended to prevent an over loosening of a fastener due to inadvertence. With a nut (14) having a means for preventing over loosening attached to a fastener (13), over loosening of the nut by an operator can be prevented, thereby avoiding falling off of the fastener from a hole (11c).
(FR) On rencontre des problèmes suivant lesquels la chute d'un organe de fixation qui fixe un couteau séparateur, qui est disposé en alignement avec une lame rotative pour empêcher ce que l'on appelle « l'effet de rebond » d'une pièce à travailler sciée par une scie circulaire à table, se produit souvent en raison d'un desserrage excessif lors du réglage de la position du couteau séparateur, conduisant ainsi à une exploitabilité inférieure. L'invention vise à empêcher un desserrage excessif par inadvertance d'un organe de fixation. Avec un écrou (14) présentant un moyen pour empêcher un desserrage excessif, fixé à un organe de fixation (13), un desserrage excessif de l'écrou par un opérateur peut être empêché, évitant ainsi la chute de l'organe de fixation à partir d'un trou (11c).
(JA)  回転する鋸刃による切断材のいわゆるキックバックを防止するために鋸刃に沿って割り刃を備えるテーブルソーにおいて、割り刃の固定ねじを緩めて位置調整をする場合に、固定ねじを緩めすぎて脱落させてしまうと作業性が悪くなる問題があった。本発明では、誤って固定ねじを緩めすぎることがないようにする。 固定ねじ(13)の先端に緩み止め機能付きのナット(14)等の脱落防止部を取り付けておくことにより、使用者が誤って緩めすぎるがことないようにしてそのねじ孔(11c)からの脱落を未然に防止する構成とする。
