Scissor with openable/closable auxiliary spring

Abstract

PURPOSE: To improve the operability of a scissor with openable/closable auxiliary spring by enabling to take a housing state in which a flat spring is retreated to a housing chamber according to the movement of a base terminal supporting part and pressure on a handle part on the other side is eliminated and a protruding state in which the handle part on the other side is pressed by protruding the flat spring over a mouth part. CONSTITUTION: When the base terminal supporting part 24 of an elastic body 22 is operated by moving to the tip part of an elongated hole, the protruding size of the flat spring 23 from the mouth part 19 is extended, and the confronting face 15a of the holding body 11 of the handle part 7 on the other side is pressurized by the free terminal part 35a of the flexible part of the flat spring 23, and both handle parts 6, 7 are opened with both blade parts 4, 5. When the base terminal supporting part 24 is operated by moving to the base terminal part of the elongated hole, the flat spring 23 is retreated to the elongated hole of the housing chamber 17, which forms the housing state, and also, the protruding length of the flat spring 23 from the mouth part 19 is shortened, and the flexible part is deflected, and held with pressure with the internal surface of the mouth part 19. A protruding flexible part is located between the confronting faces 14a, 15a of the holding bodies 10, 11 in a state in which both handle parts 6, 7 are closed, which provides no elastic force to expand both handle parts 6, 7.
(57)【要約】 【構成】 両柄部6,7間を押し広げる弾性体22は基 端支持部24から片持ち梁状に延設された板ばね23を 有している。一方の鋏片1の柄部6に設けられたばね収 納室17には弾性体案内面と弾性体突出口部19とが設 けられている。ばね収納室17に弾性体22の基端支持 部24が弾性体案内面に沿って移動可能に支持されてい る。その移動に伴い、弾性体22の板ばね23がばね収 納室17に退避して他方の柄部7に対する押圧を解除す る収納状態と、この板ばね23がばね収納室17の口部 19から突出してその自由端部35aが他方の柄部7を 押圧する突出状態とを取り得る。 【効果】 両柄部6,7を閉じたままで板ばね23を移 動させて口部19からの板ばね23の突出寸法を変える ので、弾性体22の移動操作が容易になる。弾性体22 として板ばね23を利用しているので、柄部6に対し弾 性体22を取り付ける移動操作構造が簡単になる。
