Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a stapler for binding documents, paper bags, and other papers with replaceable needles having arbitrary planar shapes and needle tip lengths.

(b) Conventional technology and problems Recently, convenient staplers are used to staple papers, especially paper bags, etc., with U-shaped needles. It has been impossible to immediately change to a needle with an appropriate tip length in order to obtain binding strength that is appropriate for the type of paper, the location of the binding, etc.

Therefore, in that case, it had to be stopped with many needles, which was unsightly and did not look good.

Furthermore, since force is applied locally to the bound paper at the needle, there is a drawback that this part tends to tear during handling of paper bags and the like.

(c) Purpose of the invention The present invention was devised in view of the above-mentioned circumstances. By pressing the paper against a wide flat surface, sufficient binding strength can be obtained, the paper can be prevented from tearing, and the appearance is also good. Moreover, it is an object of the present invention to provide a stapler capable of instantly binding papers with replaceable needles having an arbitrary planar shape suitable for the type of paper, the binding location, etc., and having the length of the needle tip.

B) Structure of the device In order to achieve this objective, the present device connects a large number of needles with arbitrary planar shapes and needle tip lengths to a receiving bracket that is pivotally supported on a lower pressing plate provided with a recessed portion. A needle storage plate that stores multiple needle groups and has stitches with a shape that matches the planar shape of the needles on the lower surface of the tip, and an upper pressing plate that has projections of arbitrary shapes corresponding to the stitches of the needle storage plate. The needle housing plate is arranged to be interposed between the upper and lower pressing plates.

(E) Embodiment of the invention Hereinafter, an embodiment of the invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the stapler according to the present invention houses a multi-needle group A in which a large number of needles a having an arbitrary planar shape are connected, and has a shape matching the planar shape of the needles a on the lower surface of the tip. A needle storage plate 1 provided with needle stitches 4 is interposed between the upper and lower pressing plates 2 and 3, and a protrusion 5 corresponding to the needle stitch 4 of the needle storage plate 1 and corresponding to the planar shape of the needle a is provided on the upper pressure plate. The needle housing plate 1 and the upper pressing plate 2 paired therewith can be detachably attached to a receiving metal fitting 10.11 which is provided in the lower pressing plate 3 provided with a recess 6 and supported by a pin 13 at the other end of the lower pressing plate 3. Stapling is possible with a needle a that has a needle tip length suitable for attachment, paper type, binding location, etc., and has an arbitrary planar shape.

As shown in FIG. 2, the needle storage plate 1 has a rectangular box with an open top, and the lower surface of the tip thereof has a bar-shaped needle a as shown in FIG. A push plate 7 is provided on the other side to hold a multi-needle group A in which a large number of needles a are connected from behind.

The push plate 7 can be slid back and forth using the inner wall surfaces of both sides of the case of the needle storage plate 1 as guides on a spring mounting rod 8 provided along the center of the case, and is supported by a coil spring 9 mounted on the spring mounting rod 8. A multiple needle group A of bart-shaped needles a stored inside the needle storage plate 1 by
is always pressed forward.

The upper pressing plate 2 is provided on the upper part of the needle storage plate 1, and has one end shaped so that it can fit into the receiving metal fitting 10, and has a flat part of the needle a corresponding to the stitch 4 on the lower surface of the other end. A bar-shaped projection 5 for pressing is provided at the center of the lower surface, and when the upper pressing plate 2 is pushed downward to release the needle a, it is then returned to its original position by the restoring force of the spring. leaf spring 1
6 is provided.

The lower pushing plate 3 is provided at the lower part of the needle storage plate 1, has a width wider than the needle storage plate 1, and has a top surface on the tip for pressing and bending the tip of the needle a corresponding to the stitch 4. A concave portion 6 is formed, and a plate spring 12 is provided on the upper surface of the other end to return the lower pressing plate 3 to its original position by the return force of the spring after binding the paper or the like.

The stapler according to the present invention includes upper and lower pressing plates 2,
The needle storage plate 1 is interposed between the upper pressing plate 2 and the needle storage plate 1, and each end of the upper pressing plate 2 and the needle storage plate 1 is pivotally supported by a pin 13.
．． 11 is fitted up to the respective positioning lines 14 and 15.

When binding papers such as documents, set the multiple needle group A of bart-shaped needles A as shown in Fig. 5 in the case of the needle storage plate 1, and use the same method as with a commonly used stapler. Then, a paper such as a document is inserted between the needle storage plate 1 and the lower pressing plate 3, and the upper and lower pressing plates 2 and 3 are pressed, and the gripping force of both the upper and lower pressing plates 2 and 3 creates a bart shape. Stitch with needle a.

At this time, the pushing force of the pushing plate 7 in the needle storage plate 1 pushes the multiple needle group A of the bart-shaped needles a from behind, so that the most advanced needle a is used.

After binding, it returns to its original position due to the return force of each leaf spring 16, 12 provided on the upper and lower pressing plates 2, 3.
Binding can be done continuously.

By this binding, documents and other paper materials are held down by the wide bar-shaped part of needle a, and are bound with sufficient strength. It can be bound.

In addition, the needle binds documents on a wide plane without applying any local force, which prevents the paper from tearing.

However, when paper with colors or patterns attached is bound, the bar surface of needle a will clearly appear on the surface of the bound paper, even if it is of course blank, so the side of needle a will be clearly visible on the surface of the bound paper. The bound papers become even more crowded.

The color of the needle a is not simply the color of the metal material itself, but it is better to add a color or pattern to at least the bart-shaped surface in order to increase the vividness.

In the above embodiment, an example was shown in which the needle a having an arbitrary surface shape was formed into a bart shape.
Needle a1 whose planar shape is quadrilateral, mouth-shaped, or oval as shown in the figure. a2. a8 multiple needle group A1. A2. A multiple needle group with A3 or any other planar shape is used.

Of course, needle a1. . It is necessary to create a shape that corresponds to the planar shape of...

By using needles of these arbitrary shapes, various papers can be bound with needles of a desired shape that matches them.

Fig. 4 shows a needle a' with a longer needle tip b' than that of the previous embodiment, which is suitable for cases where the number of sheets of paper is large or the type of paper is thick, or where the paper is to be bound. This is an example of the case.

In this case as well, the housing plate 17 houses a multiple needle group A' in which a large number of bart-shaped needles a' are connected together, and the bart-shaped protrusion 19 is paired with the storage plate 17. By providing the upper pressing plate 18, it is possible to obtain a stapler for a bart-shaped needle a' with a long needle point B, which can staple thick papers and the like.

In addition, although not shown in the drawings, a needle storage plate housing a multiple needle group of needles having arbitrary planar shapes and needle point lengths, a corresponding upper pressing plate, or only the other end of the receiving metal fitting 10
By storing commonly used U-shaped needle groups that can be fitted into , 11, and preparing a needle storage plate and an upper pressing plate, a single stapler can be used to select appropriate needles according to the purpose of use. It can be stapled.

By using this stapler, you can staple documents with the appropriate needle for the type of paper, the location, etc.

(F) Effect of the invention As mentioned above, according to the invention, papers can be stapled with a needle having a wide planar shape, so papers can be held down on a wide surface without applying force locally at the needle. Sufficient fastening provides strength, allows complete binding with a small number of staples without having to fasten with many staples as in the past, has a good appearance, and reduces paper tearing.

In addition, the beautiful planar shape of the needles appears three-dimensionally on the surface of the paper, creating an even more vivid beauty when combined with the colors and patterns added to the paper.

Moreover, the needle storage section that stores needles with various planar shapes and needle point lengths, and the paired upper press plate, are removable and replaceable, so you can easily adjust the paper type, binding location, etc. with one stapler. Effects such as being able to bind with a needle suitable for the paper are produced.
