Description

[Detailed description of the invention] The invention has a simple configuration, easy to use,
This relates to the improvement of a binding device for binding tools such as binders that has been devised for the purpose of making operations easier, etc., and includes a concave groove in the center of the longitudinal direction of the top surface and a slider that slides into the concave groove. A base is fitted so that the operating lever can be pulled outward and pushed back along the groove, and a hinge is provided on the upper surface of one side edge of the base so that the lever can be lowered outward at a substantially right angle. A luffing actuating body which is pivotally attached and has a spring attached to the pivoting part to return it to an upright state, and a tip of the luffing actuating body provided on this luffing actuating body when in the upright state, the tip thereof is on the other side edge of the base. A U-shaped binding lever that lands on the top surface and is in a closed state, and when it lands in a collapsed state, the U-shaped binding lever separates and assumes an open state, and mutually corresponding locations on the inner surface of the undulation actuating body and the top surface of the sliding operation lever. These wedge-shaped concave portions and wedge-shaped convex portions create wedge-shaped convex portions on the lower surface of the undulating actuator by sliding the sloped surfaces of both parts when the sliding operation lever is pulled out. By guiding the undulating actuator into a state in which it is in pressure contact with the side of the section, the undulating actuating body is laid down at a nearly right angle outward, leaving the binding rod in the idle state, and when the sliding operating rod is pushed back, the return force by the spring and the above-mentioned The gist is that the undulating actuating body returns to the upright state by returning the guide by sliding, and the binding rod is brought into the closed state.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A groove 2 that is continuous at both ends is formed in the center of the upper surface of the base 1 in the longitudinal direction, and a sliding operation is performed in this groove 2. The rod 3 is fitted so that it can slide in the above longitudinal direction guided by the fitting of the rails 4, 4' and the grooves 5, 5'. A hand rest 6 is provided on the base 1 (also available).
A rod-shaped undulating actuator 8 is disposed on one side edge 7 of the undulating actuator 8, and the undulating actuator 8 is pivoted by a hinge 9 so as to lie down at a substantially right angle to the outside.
A large number of U-shaped binding rods 11 are installed in the upright position, and a spring 12 is installed at the pivot point to return the undulating actuator 8 to the upright state. A fitting recess 14 is formed into which the tip of the binding rod 11 is shallowly inserted when the lever is in an upright state, and a fitting recess 14 is formed in a corresponding position on the inner surface of the undulation actuating body 8 and the upper surface of the sliding operation rod 3. A wedge-shaped recess 15 and a wedge-shaped protrusion 16 are provided, and the wedge-shaped recess 15 and wedge-shaped 16 form an inclined surface 15' when the sliding operation rod 3 is pulled out by a predetermined distance by hooking the finger on the finger grip 6. . When the tip of the binding rod 11 is opened sideways and the sliding operating rod 3 is pushed back, the undulation actuating body 8 returns to the upright state due to the return force of the spring 12 and the return of the guidance due to the sliding described above, and the tip of the binding rod 11 is opened. The binding device A is constructed by fitting into the fitting recess 14 to be in the closed state, and the binding device I is riveted to the cover R to serve as a binder.

In the figure, reference numeral 18 denotes a hook (formed as a part of the binding rod 11) used for hooking the binding hole of the paper sheet 19 and setting the sheet 19 in the binding position. Reference numeral 20 indicates a metal fitting of the base 1, and reference numeral 21 indicates a protrusion that reaches the top of the wedge-shaped protrusion 14 and locks it to maintain the open state.

Since the present invention has the above-described configuration, in order to staple the paper sheets 19, the sliding operation lever 3 is pulled out to open the binding rod 11, and then the paper sheets 19 are pulled onto the hook 18. It is sufficient to set the paper sheet 19 to the stapling position and return the sliding operation lever 3 in this set state, and to remove the paper sheet 19, perform the stapling operation described above. It is better to do the opposite.

Since the present invention is as described above, it is of course very effective because it can be configured extremely easily. In particular, by performing the pull-out operation and push-back operation on the sliding operation lever as described above, it is possible to easily remove the stacked paper sheets. It has the advantage of being able to bind and unfasten, that is, it is easy to use, and furthermore, since it utilizes the sliding movement of the inclined surface of the wedge-shaped recess and the wedge-shaped protrusion, that is, the cam mechanism, the above-mentioned pull-out operation is easy. It also has practical effects such as being able to easily perform push-back operations.
