Description

[Detailed Description of the Invention] This invention relates to a hole-punching jig that can be conveniently used to create sheets to be bound into, for example, 26-hole or 30-sized loose-leaf notebooks.

Paper for loose-leaf notebooks is commercially available with a predetermined number of holes punched at predetermined positions.

Therefore, in order to use this paper as a regular notebook, it is sufficient to purchase this paper and bind it into a loose-leaf notebook, but the user may want to bind paper other than such regular paper.

For example, as copying technology has recently developed and it has become possible to copy anything, it has become necessary to bind the copied materials, to bind newspaper or magazine clippings, or to bind catalogs. This is for storing things such as books.

Conventionally, multi-hole punches used for this purpose are large, take up space, and are very expensive, so they are not generally used and are extremely inconvenient in the cases described above. It was something that

Therefore, a drilling jig that solved this problem was invented by the applicant for this utility model registration, and has already been filed for a patent (Patent Application No. 54-0
No. 46928).

This invention further improves this and increases usability.

One embodiment of this invention will be explained with reference to the drawings. In Fig. 1, 1 is a one-hole punch, an arm 3 is pivotally attached to a base 2 by a shaft 4, and a blade whose upper part is supported by a shaft 5. (not shown) to make a hole in a sheet of paper 7 (see FIGS. 5 to 8) inserted into a groove 6 provided in the base 2.

A projection 8 having a circular tip is provided at the front of the hole punch 1, that is, above the groove 6 of the base 2.

Reference numeral 9 in FIGS. 2 to 8 is a ruler used together with the one-hole punch 1.

This ruler 9 is for grasping a sheet of paper 7, and a part of the ruler 9 is made to protrude, and the vicinity of the tip of this protruding part 10 is used as a hinge 11 to connect the upper plate 12 and lower plate 13 (see FIG. 5). A magnet plate 14, 15 is attached to a part of the plastic plate (both synthetic resin plates), and a large number (for example, 26) of recesses 1 are formed on one edge near the hinge 11.
6゜16... (top plate 12) and several recesses 1
7 (lower plate 13).

Projections 18 are provided on the surface of the upper plate 12 along the recesses 16, 16, . . . .

A protrusion 19 is provided on the lower plate 13 to prevent misalignment with the upper plate 12 and to position the paper sheet 7.

A portion of the upper plate 12 is bendable, making it easier to operate (see Figure 6).One end of this portion protrudes laterally than the other portion, making it easier to grasp. There is.

This drilling jig constructed in this way is used as follows.

First, to make multiple holes such as 26 holes, open the ruler 9 as shown in FIG. The tip of 7 is the upper plate 120
It is made to come into contact with a protrusion 18 provided on the surface.

At this time, one edge (left edge) of the paper sheet 7 is brought into contact with the protrusion 19.

Next, the upper plate 12 is closed, and the state shown in FIG. 6 is changed to the state shown in FIG. 7.

In the state shown in FIG. 7, the two magnetic plates 14 and 15 attract each other, so the sheet of paper 7 located between them
will be held firmly in the meantime.

In this state, the protrusion 8 at the tip of the partial punch shown in FIG.

If this drilling is performed sequentially from the end, a desired number of holes 7a can be made.

To remove the perforated paper sheet from the ruler 9, raise a part of the upper plate 12 with your finger as shown in FIG. 6, and pull it further upwards in the figure. state.

Next, when the number of holes 7a to be drilled into the sheet of paper 7 is 2 or 3 holes, and the distance between the holes is determined, the sheet of paper 7 is placed on the ruler 9 using the steps shown in FIGS. 5 to 7. After pinching, turn it over so that it is in the state shown in FIG. 8, and press the protrusion 8 of the hole punch 1 against the recess 17 to punch it.

In the embodiment described above, the protrusion was provided on the negative hole punch side and the recess was provided on the ruler side, but the reverse may be used.

Also, a magnetic plate was attached to both the upper plate and the lower plate, but instead of this, the magnetic plate was attached to either the upper plate or the lower plate, and the other plate was attracted to the magnetic plate. For example,
A magnetic plate such as an iron plate may be attached.

Furthermore, the position and structure of the recess or protrusion (the recess in the embodiment) can be changed.

What is shown in FIGS. 9 to 11 are modified embodiments of this invention.

To explain this, first of all, the one shown in FIG.
is provided, and the plate body 20 is fixed to the lower plate 13 with screws 21.

The upper plate 12 side has a similar structure. In the one shown in FIG. 1, a dovetail groove 22 is provided on the plate body 20, and a dovetail-shaped protrusion 23 is provided on the lower beam 13, and by fitting this protrusion 23 into the dovetail groove 22, the plate body 20 is attached to the lower adhesive 13. It is fixed at (
(See Figure 11).

In these two rulers 9, the position of the recess 17 is recessed toward the center from one edge of the lower magnification 13 (in the front order in the figure), so the -hole punch 1 is also slightly different from the one in Figure 1C. , the groove 6 is deep, and the protrusion 8 is attached to the tip of the carrier 2.

As mentioned above, this device grips the paper sheet to be inserted using the adhesion force between two magnetic plates, or between a magnetic plate and a magnetic plate that is a member that is attracted to the magnetic plates. Because of this, the force for gripping the paper sheet is extremely large, which has the advantage that the paper sheet will not deviate from the ruler in the chamber hole.

In addition, since recesses or protrusions with different gaps are provided on both plates, it is possible to drill holes with different numbers by simply turning the ruler over. .
