DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This application relates to a binder fitting for multi-hole paper such as computer recording paper.

BACKGROUND TECHNOLOGY 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. and an elongated holding member having a thin U-shaped cross section and having 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 that it can move slightly in the longitudinal direction, and the presser member is constantly compressed in the longitudinal direction by this hinged portion. In addition, an elastic spring is interposed to rotate and bias the binding rods in the direction of opening, and notches are formed in the upper part of some of the binding rods, and the ends of the elongated holes provided on the lower surface of the presser member are provided. Furthermore, 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 bound multi-hole paper is extracted for use or transferred to another binder metal fitting, the The paper fell apart,
When binding the binder metal fittings again, the binding has to be aligned in the binding direction, and there is an inconvenience in handling that it takes time to close the binder metal fittings.

Means for Solving the Problem Therefore, the present application is configured so that the binder metal fittings can also be closed by the operation of closing the cover, and the extracted sheets can be kept in a bound state, so that they can be handled easily. The purpose of the present invention is to provide a convenient binder metal fitting, and its main point is that a support is provided on one longitudinal edge of a substrate on which a large number of binding rods and at least two binding tubes are implanted on the upper surface. The lower edge of an engagement plate, the upper edge of which is provided by bending a holding piece that suppresses the upper surface of a holding member (to be described later), is pivotally attached to the upper part of this support piece, and When the engagement plate is in an upright state, a line connecting the attachment points at both ends is located inward from the pivot point of the engagement plate, and when the engagement plate is in a prone state, so that it is located outward from the pivot point of the engagement plate,
It is characterized by being composed of a binding member having an elastic spring attached in a loaded state, and a holding member having a connecting rod protruding from the inner surface of a base plate that comes into contact with the tip of the binding rod to be inserted into and removed from the forestomach binding tube. This is a binder metal fitting.

Function When binding sheets of paper, when the engaging plate is rotated with the fingertips in the prone direction against the elastic spring that presses the engaging plate in the upright direction, the engaging plate is rotated in the process of rotation. The line connecting the attachment points at both ends of the compression spring, which was located inward from the pivot point of the plywood, crosses the pivot point of the engagement plate and moves outward, so the compression spring now attaches to the engagement plate. is biased into a prone state, and the engagement plate automatically falls down and maintains that state. After releasing the restraining state of the presser member in this way, lift the presser member and pull out the connecting rod from the binding rod. In this state, insert the binding hole of the paper into the binding rod and push the connecting rod into the binding rod again. The base of the holding member covers the upper end of the binding rod, and then the engagement plate is raised against the elastic spring. Then, the line connecting the attachment points at both ends of the elastic spring, which was located outward from the pivot point of the engagement plate, moves inward from the pivot point of the engagement plate, so the elastic spring now moves the engagement plate in the upright direction. , and its upright state is maintained.

In addition, when removing part or all of the paper from the stacked state, if the engagement plate is rotated in the upside-down direction against the elastic spring, the engagement plate will fall down as described above, and the paper will be The paper is pulled out from the stacking member along with the holding member, and the extracted paper is held by the connecting rod in the same way as in the stacked state, so the extracted paper can be pulled out from the stacking member without worrying that it will shift apart. In the stretched state, the paper can be again inserted through the binding hole through the binding rod and stapled.

Embodiments Below, the embodiments of the present application will be described in detail with reference to the drawings.

It is attached between the engaging plate 5 and the central part of the bent portion 7, and the binding member 12 is configured as described above. The holding member 13 is in contact with the line of the binding rod 2 on a long substrate 14 whose longitudinal side edges are curved downward, and the binding tube 3,
Connecting rods 15, 15 are provided vertically to be inserted through the holes 3, respectively. 16 is a mounting hole.

Therefore, when in use, the binder metal fittings of the present invention are fixed to the back inner surface of the back cover of the cover member through the mounting holes 16, and under normal conditions, as shown by the imaginary line in FIG. Substrate 14 of member 13
is in contact with the upper end of the binding rod 2, and the line n connecting both ends of the elastic spring 11 is located inward from the pivot portion of the engagement plate 5, so that the engagement plate 5 is elastically pressed in the upright direction. The engagement plate 5 is held in an upright state by the force, and the restraining piece 9 restrains the substrate 14 of the pressing member 13 from above. When trying to load paper from this state, press the engagement plate 5 with your fingertips.
It is rotated in the prone direction against the elastic spring 11. Then, when the line n connecting both ends of the compression spring 11 crosses the pivot point of the engagement plate 5, that is, beyond the dead point, the engagement plate 5 is biased by the elastic pressure in the downward direction, and the engagement plate 5 is automatically the first
