Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention is a punching device for punching holes in documents, cars, etc., which is convenient for storage and portability, and can be used for various purposes. The present invention relates to a thin multi-purpose punch that can be used.

[Prior art] Conventionally, thin punch devices include the "hole-measuring device" of Utility Model Publication No. 44-10548, the "document puncher" of Japanese Utility Model Publication No. 52-26354, and the "document puncher" of Japanese Utility Model Publication No. 57-42706. A "punch provided in a document binder" and the like are disclosed.

[Problem to be solved by the invention] The above-mentioned "perforator" has the perforator blade 3 mounted upward on the blade base plate 1, and the next "document perforator" also has the perforator blade 3 mounted upward on the base plate 10. The perforating blade 20 is fixed upward, and the upper surface of the blade edge is horizontal. Therefore, strong force is required for perforation, and only about 1.2 sheets of paper can be perforated. There were some problems, such as uncut parts.

In addition, the "cutting punch installed in a document binder" is one in which a cutout punch 11 is attached to the upper plate 9, and the cutting edge of the cutout punch 11 is formed into two forks, but as in the present case,
If the punch 11 or the punch moves in and out of the hole 13 in a circular motion during drilling, if it is bifurcated, punch waste may be left behind during drilling.

In addition, in order to obtain punch blades for the three punches mentioned above,
Both require a power machine to swage the punch blade, making it troublesome to get one.

The present invention was made in order to eliminate such problems with the conventional technology, and an object of the present invention is to provide a thin multi-purpose punch that has an extremely simple structure, is easy to assemble, and can perform reliable perforation. This is what it says.

[Means for Solving the Problems] The present invention has been made to solve the above problems, and includes two rows of actuating bodies that rotate outward in the longitudinal center of a rectangular base. In addition to being freely attachable, punch holes are formed on both sides of the base at different positions for different types of punching, and punch blades that fit into the punch holes are fixed to the lower surface of the actuating body. With this, various types of punching such as 1-hole punching, 2-hole punching, 3-hole punching, 4-hole punching, 66-hole punching, etc. can be performed with one machine.

In addition, when punching paper, the tip of the punch blade is formed into a wave shape consisting of four or more peaks and valleys, and a sharp cutting edge is attached to the outer periphery, so that the punch hole can be cut reliably and cleanly with less force. A department was established.

Note that this thin punch is provided with a mounting portion on the base or the operating body so that it can be used for a variety of purposes by being attached to files, scales, staplers, etc., for example.

[Operations] Since the present invention is constructed as described above, it is possible to punch holes from one large hole to two holes, three holes, four holes, and six holes with a single stand, and can also punch holes such as files, scales, etc. By combining it with a stapler, etc., the scope of use can be expanded.

The punch blade that is fixed to this thin punch is made of a thin stainless steel plate with a thickness of 0.3 mm and has a corrugated tip consisting of a peak and a trough, and a sharp cutting edge on the outer periphery. This makes it possible to drill holes reliably and cleanly with a small amount of force.

[Example] Example 1 Example 1 will be explained with reference to FIGS. 1 and 2. Example 1 has one large punch hole, two holes, and three holes.
This is a thin multi-purpose punch that can make five types of holes: holes, 4 holes, and 6 holes. Fig. 1 is a perspective view of the punch in an unused state with two operating bodies 2 open, and Fig. 2 This is a cross-sectional view taken along the line A-A in FIG. 1, where l is a base, 2 is an operating body, and 3 is a waste receptacle.

The rectangular base l has a total of 9 punch holes for 6-hole punches and 3-hole punches on the front side in Figure 1, and 4 punch holes for 4-hole punches on the rear side. On both sides of the punched hole 4, a restraining protrusion 5 with an upwardly bent tip is formed in order to restrain the punched paper toward the base l side and to always expand the actuating body 2 at a constant interval.

The actuating body 2 is rotatably attached to the base 1 via a shaft 7 at the base 6, and one punch blade 8 is provided on the lower surface of the actuating body on the front side for punching three large bunch holes. A total of three small operating bodies 2B are attached to the center and both sides as shown in the first figure. Further, two medium-sized actuating bodies 2C each having three punch blades 8 are installed between the three actuating bodies 2B.

Furthermore, on the rear side of the base 1, a small actuating body 2B to which one punch blade 8 is attached for punching a four-hole punch hole is rotatably mounted on the base 1 at standard spacing positions. A total of 13 punch blades 8 are fixed to a total of 9 actuating bodies 2.
can move in and out of 13 bunch holes 4 bored in the base l.

The multi-purpose punch of the present invention is formed into a thin shape for convenience in storage and portability.For this reason, as for attaching the punch blade, as in the above-mentioned conventional technology, the fixing part of the punch blade is attached to the punch blade. Instead of being provided on the outside of the main body, there is a hole provided inside the main body as shown in Figure 2, and this punch blade 8 punches a thin metal plate (0.3 mm stainless steel plate in the unexamined example). A cylindrical part 9 is formed by ironing and drawing, and a tapping hole 11 with an inclined surface part 10 formed on the upper surface is provided, and a cutting edge part 14 consisting of a top part 12 and a trough part 13 is formed in a wave shape at the tip. An overhanging portion 15 hardened by punching and ironing is formed on the outer periphery of the cutting edge portion 14.
form.

Then, this punch blade 8 is inserted into the actuating body 2 as shown in the second figure.
The outer diameter of the mounting shaft 16 is slightly larger than the inner diameter of the mounting hole 11 of the punch blade 8, and the length of the mounting shaft is , the height is approximately the same as the height of the trough portion 13 of the punch blade 8 shown in FIG.

In order to attach the punch blade 8 to the mounting fil+ 16 of the actuating body 2 configured in this way, as shown in FIG. When pushed in, the outer diameter of the mounting shaft 16 will match the punch blade 8.
Although it is molded slightly larger than the inner diameter of the access hole 11,
An inclined surface portion 10 is provided around the upper surface of the mounting hole 11, and the receiving shaft 16 is made of synthetic resin 81 (material) and is hollow, so when the punch blade 8 is strongly pressed, the mounting shaft 16
It is fixed as shown in the second figure by the elasticity of.

Since the inner peripheral part of the lower surface of the mounting hole 11 of the punch blade 8 comes into contact with the outer periphery of the mounting shaft 16, the punch blade 8
does not come off the receiving shaft 16.

Next, as shown in FIG. 2, the waste receptacle 3 is formed to have a U-shaped cross section, and is fitted onto the lower surface of the base 1, with a punch waste storage section 17 provided between the two.

In FIG. 1, reference numeral 18 indicates the center of the paper during the punching operation, and reference numeral 19 indicates a paper insertion opening formed between the base 1 and the lower surface of the restraining protrusion 5. Also, the punch hole 4 in Figure 2
As shown in the figure, the hole diameter at the bottom surface of the hole 4 is made wider than the hole diameter at the top surface, so that punch debris can be easily discharged.

Since the first embodiment of the present invention is configured as described above,
First, to punch a l-sized hole, insert paper such as a document or card into the paper insertion slot 19 on the bottom of one of the seven small actuators 2B, and then When the upper surface is suppressed, first the restraining protrusion 5 that is in contact with the lower surface is pushed down,
The four peaks 12 of the sharp cutting edge 14 of the thin metal punch blade 8 fixed to the lower surface of the operating body 2 first bite into the paper, and by further pressing, the troughs 14 cut the paper. By cutting, binding holes can be punched reliably and easily.

When the hole is finished and the pressure on the actuating body 2 is released, the actuating body 2 rotates upward due to the elastic force of the restraining protrusion 5 made of flexible synthetic resin, and the punch blade 8 also rotates upward. Since the perforated paper remains in the insertion slot 19 due to the upward movement, the paper can be taken out immediately.

Next, in order to punch two holes in the paper, in FIG. 1, among the four small actuators 2B installed on the rear side,
The hole is punched using the two inner actuating bodies 2B. After inserting the paper into the insertion slot 19 on the bottom of the actuating bodies 2B and aligning the center with the display 18, press the actuating bodies 2 in the same way as above. This will allow you to drill two prescribed holes 8cm apart. The operating method and the like are the same as those described above, so a description thereof will be omitted.

Next, in order to punch three holes, the three small-sized actuators 2B attached to the front side in Fig. After inserting the paper into the insertion opening 19 on the lower surface of the body 2, only the three small actuating bodies 2B are sequentially pushed down to perform three large holes.

Furthermore, in order to punch four holes, all four small actuators 2B on the rear side are used to punch the holes, and the paper is inserted into the four insertion slots 19, and the center of the paper is indicated at 18. If the four actuating bodies 2B are pressed down after adjusting the hole distance, the specified holes can be drilled with a hole spacing of 8 cm.

Furthermore, in order to punch six large holes, two medium-sized actuators 2C are used to punch the holes, and paper is inserted into the insertion slots on the bottom of all the actuators 2 on the front side. When 2C is respectively suppressed, 3
Two punch blades 8 fit into the punch hole 4 at the same time to perform punching. In this case, unlike a conventional punch blade,
The punch blade 8 of the present invention is extremely thin and has a sharp cutting edge, so it can punch holes easily with less force than conventional punch blades.

The punching method, paper removal, etc. are the same as those described above.
