Description

[Detailed Description of the Invention] The present invention relates to a file binding tool that can create binding holes in files to be filed without any binding holes and then bind the sheets as they are.

For this kind of paper leaf binding tool that also serves as a punch, for example, the tips of cylindrical supports installed on both sides of the base plate are formed into punching blades, and one side of the base plate is bent into an L shape to form a side plate. None, the push plate and side plate are connected with a butterfly plate,
The push plate has a structure in which a hole corresponding to the punching blade is bored, a handle is protruded from the center of the front side, and a locking side plate is glued to the inner surface of the side plate, as disclosed in Publication of Utility Model Publication No. 51-32487. It has since become publicly known.

However, in this type of device, the press plate above the cylindrical column that is the binding rod is free to slide upwards, and there is no mechanism to prevent this movement, so the binding tool may be flipped upside down. There is a risk that the paper sheets stored in these devices may easily fall out from the support when subjected to vibrations, and therefore, it is extremely inconvenient to store and carry the device in a bag, etc. The dot was hot.

The purpose of the present invention is to solve these problems.The present invention is designed to provide a punching rod with a blade at its upper end on the top surface of the base, and a support and a locking rod at a location near the rear. erected above the base, and has a die hole corresponding to the punch-cum-stacking rod, and a through hole for the penetration of the support and locking rod. Even when the mounting plate is dammed, there is a gap between the top surface of the binding rod which also serves as a punch, with a gap in which the file can be inserted. An operating rod is provided to enable the blade of the binding rod to punch out binding holes in sheets to be bound, and the head of the locking rod is provided with an operating rod to push down the clamping plate and the blade of the binding rod also serves as a punch. The gist of this invention is to provide a hook that engages the tip of the operating rod and prevents it from returning when the die is located in the die hole of the holding plate.

Examples of the present invention will be described below.

Figure 1 is a perspective view showing the operating state of perforation and binding of the paper to be filed, and Figure 2 is the figure 1 A-A.
3 is a perspective view showing the bound state, and FIG. 4 is a sectional view taken along line A'-A' in FIG.
On both sides of the front end of the upper surface of the base 1 fixed to the cover body 2, there are erected binding rods 2, 2' which also serve as punches and whose upper ends are blades, and at the center of the rear end, rotatable rods 2 and 2' are provided. A locking rod 5 having a hook portion 4 at the upper end is erected at the lower end of the rear end of the pillar 3, and the rear edge is integrally connected to the base 1 above the base 1 to form a character shape. A clamping plate 6 is disposed so as to be able to freely slide with elasticity in a direction perpendicular to the base 1. Die holes 7, 7' through which the punching rods 2, 2' can pass are provided at positions corresponding to the punching rods 2', and similarly, support rods 7 and 7' are provided at positions corresponding to the support columns 3 and locking rods 5, respectively. Through holes 8 and 8' are formed through which the support rod 3 and the locking rod 5 can pass, and the top end of the support column 3 always extends through the through hole 8, and an operating rod 9 can be freely rotated in the vertical direction on the protruding portion thereof. In addition, it is configured to be fixed so that it can be raised and lowered freely. In its natural state, the clamping plate 6 maintains a configuration in which there is a gap between its lower surface and the upper end of the punching levers 2, 2' to allow insertion of paper to be filed by an appropriate thickness. (See Figures 1 and 2). This file binding tool is first operated with the operating lever 9 in an upright state, that is, with the bulge 10 near the proximal end facing down and in contact with the upper surface of the clamping plate 6.
When pressed downward, the clamping plate 6 is pushed down against the spring force by the action of the screw, and the punching rods 2, 2' penetrate into the die holes 7, 7' to form holes. As shown in FIGS. 3 and 4, the upper end hook portion 4 of the locking rod 5 that protrudes through the through hole 8' of the clamping plate 6 is turned over so that the operating rod 9 is in a prone position, and the support 3 is rotated. The file state is achieved by moving the operating rod 9 and locking the tip of the operating rod 9.

Since the present invention is as described above, even if the paper does not have binding holes punched in advance, there is no need to separately punch holes with a punch, etc., and the paper can be punched and stapled at the same time. Of course, it is very convenient as it saves the labor and allows the file work to be done very easily, but especially in this invention, it is possible to press down the clamping plate on the top of the support and connect the die hole with the binding rod that also serves as a punch. An operating lever is provided on the head of the locking lever to enable punching of binding holes in the paper sheets to be bound using the blade of the blade, and the operating lever is used to push down the clamping plate so that the blade of the binding lever that also serves as a punch is inserted. A hook is provided that engages the tip of the operating rod and prevents it from returning when it is positioned in the die hole of the clamping plate, so that the tip of the operating rod can be attached to the locking rod during non-drilling work. To firmly prevent upward movement of a clamping plate by engaging with a hook part at the top end, and to surely prevent paper sheets stacked in a punch-combining stacking rod from being pulled out upwards. This has the effect of fully achieving the above-mentioned object of the present invention.
