Description

[Detailed Description of the Invention] Industrial Application Field The present application relates to a binder metal fitting for multi-hole paper such as computer recording paper.

BACKGROUND ART Conventionally, in order to easily and reliably bind multi-hole paper, a vertical plate was bent into an L shape in the middle of a long board on which many binding rods were embedded. It is composed of a long binding member, and a long holding member whose cross section is formed into a thin U-shape and has a long hole spaced apart on the lower surface for intervening the upper end of the binding rod. One side edge in the longitudinal direction of the presser member is hinged to the upper edge via a shaft rod so as to be able to move slightly in the longitudinal direction, and the presser member is constantly pressed in the longitudinal direction by this hinged portion. , and an elastic spring that biases the binding levers to rotate in the direction of opening is interposed, and notches are formed in the upper part of some of the binding levers, and cutouts are formed in the ends of the long holes provided on the lower surface of the presser member. A binder metal fitting configured to engage with the notch in the direction of the elastic force of the elastic spring to hold the upper part of the binding rod in a closed state is known from Japanese Utility Model Publication No. 15697/1983.

Problems to be Solved by the Invention However, according to the conventional binder metal fittings described above, when all or a part of the loaded multi-hole paper is extracted for use or transferred to another binder metal fitting, the The paper fell apart,
When binding the paper to the binder metal fitting again, there was an inconvenience in handling that the binding holes had to be aligned in the binding direction.

Means for Solving the Problems Therefore, the present application provides a binder metal fitting that is convenient to handle by ensuring the stapled state of the binder metal fitting and holding extracted sheets in the stapled state. The gist of this is that a large number of binding rods and at least two binding tubes are implanted on the top surface, and a locking piece is placed upright on the side edge of the base plate, and the long side When an operating shaft extending in the direction and having an acupressure part at the outer end is engaged with the base plate together with a bearing so as to be movable in the axial direction, the movement in the axial direction is restricted, and when one of the movement restrictions is reached in the upright state, The lower edge of the engagement plate, which comes into contact with the inner surface of the locking piece to prevent it from falling down, and which is provided with a bending piece on the upper edge to suppress the upper surface of the holding member, which will be described later, is operated as described above. In addition to being attached to the shaft, between the board and the engagement plate,
A binding member is provided with an elastic spring that always applies an elastic force to the engagement plate in the downward direction and in the direction of contact with the locking piece, and the binding member is provided with the binding member on the inner surface of the base plate that contacts the tip of the binding rod. This binder metal fitting is characterized by comprising a holding member having a protruding connecting rod that can be inserted into and removed from a pipe.

Function When loading paper, when the end of the operating shaft is pressed against the elastic spring, the engagement plate moves within a limited range to one side, and the engagement plate separates from the locking piece. When it comes off, the engagement plate is laid down by the elastic spring. Next, lift the presser member,
Pull out the connecting rod from the binding tube, insert the binding hole of the paper into the binding rod in this state, insert the connecting rod into the binding tube again, cover the upper end of the binding rod with the base of the holding member,
Thereafter, the engagement plate is erected against the elastic spring. Then, while the engagement plate is fully upright, it moves in the other direction within the range limited by the elastic spring, and the engagement plate automatically comes into contact with the inner surface of the locking piece, preventing it from falling down. At the same time, the upper surface of the board of the holding member is held down by the holding piece, and the binding is completed. In addition, when removing some or all of the paper from the stacked state, press the operating shaft against the elastic spring, and as mentioned above, the engagement plate will fall down, allowing some or all of the paper to be removed. The paper is pulled out from the stacking member together with the presser member, and the extracted paper is held by the connecting rod in the same way as in the stacked state, so there is no fear that the extracted paper will shift apart. Therefore, in this state, it is possible to insert the binding hole of the paper through the binding rod again and bind the paper.

Embodiments Below, the embodiments of the present application will be described in detail with reference to the drawings.
Reference numeral 1 denotes a long board, both longitudinal edges of which are bent downwards, and a large number of binding rods 2...2 placed at required intervals in the longitudinal direction of the upper surface thereof, and 2 binding rods 2 at symmetrical positions from the center. Book cylindrical binding tubes 3, 3 are implanted,
A bearing sleeve 4, a notch 5 located at the center, and an upright locking piece 6 are provided on one side edge of the base plate 1, respectively. Reference numeral 7 denotes an operating shaft that extends along the longitudinal direction of the substrate 1 and is rotatably and movably supported in the axial direction by the bearing sleeve 4, and has an L-shaped bend at its outer end. A shiatsu part 8 is formed. 9 has a shaft bearing cylinder 10 on its lower edge that intervenes in the notch 5 and is allowed to move within a limited range in the longitudinal direction, and the operating shaft 7 is fixed to this to prevent its rotation. It is an engagement plate that rises and falls as the engagement plate 9 rises and falls, and has a holding piece 13 bent in an L-shape on its upper edge to suppress a substrate 12 of a holding member 11 from above, which will be described later. When it moves to one restricted end, its outer surface abuts the inner surface of the locking piece 6, preventing it from falling down. 1
Reference numeral 4 denotes a spring which is interposed between the bearing sleeve 4 and the bearing sleeve 10 and constantly presses the engagement piece 9 in the direction in which it comes into contact with the locking piece 6, and always presses the engagement plate 9 in the downward direction.
