Projecting above the sheath plate through notch holes provided at both side edges of the operating plate so that the tips of the pair of binding rods can be opened and closed by the bending action of the valley fold and the mountain fold of the pair of operating plates, and the operating plate At both ends of the inner edge joint part, engaging concave holes are provided by notching the inner edge, and at both end positions of the sheath plate, support parts are provided at lower left and right positions of the finger rest part, and a lower central position thereof. A narrow neck portion that bends forward and extends in a slanted shape, and intervenes in the engaging recess at the tip, While vertically tilting the supporting part of the lever part, which is continuous with the action part that pushes up from the lower surface of the plate and bends into a mountain fold, between the left and right upper edges of the neck part and the upper surface of the operating plate, The lever means is provided with an engaging / disengaging locking means for locking the lever piece in the upright state to hold the valley-folded state of the actuating plate. Locking projections provided on the left and right upper edges of the neck portion, and locking holes provided on the upper surface of the operating plate, or the locking means has locking projections provided on the left and right upper edges of the neck. On the upper surface of the operating plate, a locking projection is formed on the upper surface of the operating plate, or when the locking means erects the lever piece, the upper and lower edges of the neck are forced to ride over. It is provided.
作用 しかして書類などを綴り込んだ状態においては、一対
の作動板が谷折り状に屈曲して一対の綴杆が閉じられ、
かつ、テコ部片は、係止手段により起立状態に保持され
ており、この状態から指当部を介してテコ部片を外方に
強く押圧すると、テコ部片は鞘板に対して垂直傾動し、
この傾動により、係止手段の係止状態が解かれ、この状
態からさらに指当部を外方に強く押圧すると、作用部に
よって一対の作動板が下面から押し上げられて、一対の
作動板は山折り状に屈曲すると共に、一対の綴杆が開
き、この状態で書類などの綴り込みが行われる。Action However, when a document or the like is bound, the pair of operating plates are bent in a valley fold shape to close the pair of binding rods.
Moreover, the lever piece is held in an upright state by the locking means, and when the lever piece is strongly pressed outward from this state via the finger rest, the lever piece tilts vertically with respect to the sheath plate. Then
Due to this tilting, the locked state of the locking means is released, and when the finger rest is further strongly pressed from this state, the pair of operating plates are pushed up from the lower surface by the action part, and the pair of operating plates are crested. While bending in a fold shape, the pair of binding rods are opened, and in this state, a document or the like is bound.
またこの状態から、一対の綴杆を閉止するときは、従
来と同様に、綴杆を指で内方に押圧すると、一対の作動
板が谷折り状に屈曲して、一対の綴杆が閉じると共に、
一対の作動板の屈曲作用に伴ってテコ部片は垂直傾動し
て係止手段が係止されない位置まで起立する。Further, when closing the pair of binding rods from this state, as in the conventional case, when the binding rods are pressed inward with fingers, the pair of operating plates are bent in a valley fold shape and the pair of binding rods are closed. With
The lever piece vertically tilts with the bending action of the pair of actuating plates and stands up to a position where the locking means is not locked.
次いでこの状態からさらにテコ部片の指当部を内方に
強く押圧すると、頸部の上縁が作動板の上面を摺接しな
がら押圧し、この押圧作用により作動板はそれの保有す
る弾性力により多少とも撓むので係止手段は圧接状態で
係止され、かつ、指当部が起立状態に復する。When the finger rest of the lever piece is further strongly pressed inward from this state, the upper edge of the neck part presses the upper surface of the operating plate while making sliding contact therewith, and this pressing action causes the operating plate to retain its elastic force. Because of this, the locking means is locked in a pressure contact state and the finger rest portion returns to the upright state.
従って、この状態で外部からの衝撃が加わって、一対
の作動板が山折り状に屈曲しようとしても、係止手段の
係止によって作動板の山折り状の屈曲は阻止されるか
ら、一対の作動板の谷折り状態は保持される。Therefore, even if an impact is applied from the outside in this state and the pair of operating plates try to bend in a mountain fold shape, the mountain fold bending of the operating plate is prevented by the locking of the locking means. The valley-folded state of the operating plate is maintained.

図仮想線（ロ）で示すように倒伏する。Then, in the state where the documents etc. are spelled in, the second,
As shown by the solid line in FIG. 4, the pair of actuating plates (4) and (4) are bent in a valley fold shape to close the pair of binding rods (5) and (5), and the lever piece (8). Stands up and the locking projection (13) b locks the operating plate (4) with the upper edge (10) a of the neck (10) pressing the upper surfaces of the operating plates (4) and (4). The lever piece (8) is locked in the hole (13) a, and when the lever piece (8) is strongly pressed outward from this state through the finger rest (9), the lever piece (8)
Vertically tilts around the bearing (12) with the sheath plate (1) as a fulcrum, and this tilting causes the locking holes (13) a, (13) a and the locking projections (13) b, (13) b. 4 and the state shown by the phantom line (a) in FIG. 4 is released, and when the finger rest (9) is further strongly pressed outward from this state, the action portion (11) causes the pair of operating plates to move. (4) and (4) are pushed up from the lower surface, the pair of actuating plates (4) and (4) are bent in a mountain fold shape, and as shown by the phantom line in FIG. ), (5) are opened and the lever piece (8) is
Proceed as shown by the phantom line (b).
従って、この状態で書類などが綴杆（５），（５）に
綴り込まれる。Therefore, in this state, documents and the like are bound on the binding rods (5) and (5).
また、第２図仮想線で示すように、一対の綴杆
