両開き綴金具

Double-opening binding metal device

Abstract

(57)【要約】 【課題】 簡単且つ安価に構成すると共に綴込み操作性 を十分に発揮することができる両開き綴金具を提供す る。 【解決手段】 綴杆10またはこれに対応する綴管12 を保持する両側板14の各一側縁部14aと、ファイル 台紙に固定する基板16の両側縁部16aとをそれぞれ ヒンジピン18を介して着脱可能にヒンジ結合する両開 き綴金具において、基板16の両側縁部16aに沿う両 側部上に、それぞれ弾性伸縮作動部34および弾性可撓 ロック機構部36を有すると共に、ヒンジピン18を保 持32a、36dしてこれを側板14とのヒンジ結合お よび開放の2位置A、B間で移動するスライド操作板3 0と、このスライド操作板30を被覆すると共に、その 2位置A、Bを規制する被覆板40とを設けて構成す る。
PROBLEM TO BE SOLVED: To provide a double-opening binding metal device which is constructed simply and inexpensively and also can exhibit filing operability sufficiently. SOLUTION: This binding metal device is so constructed that the respective one-side edge parts 14a of two side plates 14 holding binding bars 10 or binding tubes 12 corresponding thereto and the opposite side edge parts 16a of a base plate 16 fixed on a file ground board are hinge-connected removably by hinge pins 18 respectively. In this construction, sliding operation plates 30 which have a resilient extension-contraction operation part 34 and a resilient flexible lock mechanism part 36 respectively and also hold 32a, 36d the hinge pins 18 and move them between two positions of the hinge connection with the side plates 14 and opening, and covering plates 40 which cover the sliding operation plates 30 respectively and regulate them at the two positions, are provided on the opposite side parts along the opposite side edge parts 16a of the base plate 16.
