Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to files. More specifically, the present invention relates to a filing tool capable of facilitating binding and releasing operations of a sheet and a magnetic attraction sheet used for the filing tool.

[0002]

2. Description of the Related Art Conventionally, a flexible tape 73 is passed through two holes 72 formed in a file sheet 71 (usually paper) as shown in FIG.
There is known a filing tool 75 that can be tightened with. In addition, the hole 72 of the seat 71 is closed by an openable / closable ring, or as shown in FIG.
There is known a filing tool 83 for clamping 1 and a sheet for removably inserting a sheet into a transparent bag bound in a notebook shape.

On the other hand, there is also known a scrapbook in which a cutout of a newspaper or the like is attached to a notebook with glue.

[0004]

The filing tool which is bound by the metal fittings 74 and the ring has a hole 72 in the paper.
It takes a lot of time to open the holes, and there are many paper holes 72.
It is extremely troublesome to pass the tape 73 and the ring in order. Further, the filing tool 83 of the type in which the pressing metal fitting 82 clamps is difficult to open and close the pressing metal fitting 82 against the spring 81, and if the spring force is weakened, the paper in the middle is easily removed.
There is a problem that even if you try to extract only one sheet, other sheets will fall apart.

Further, it is troublesome to insert a transparent book or a scrapbook into the bag one by one or attach the scrapbook to a mount.

The present invention eliminates the inconvenience of such conventional filing tools, and provides a filing tool which is easy to bind and can be easily attached to and detached from one or two sheets or a large number of sheets. It is an object.

[0007]

The filing tool according to the first aspect of the present invention is characterized by comprising a cover material and a magnet provided on the cover material.

The magnet may be a permanent magnet.

The permanent magnet can be made of a magnetic metal.

The permanent magnet can be composed of magnetic powder such as ferrite powder and a binder such as thermoplastic resin, thermosetting resin and rubber.

On the other hand, the magnet may be an electromagnet.

The electromagnet preferably has a slide resistor.

Further, it is preferable that the electromagnet has a switching means for switching between excitation and demagnetization. The "demagnetization" is a concept including a case where a weak magnetic force remains, and in that case, the switching means serves as a means for switching the magnetic force of the magnet.

Further, it is preferable that the electromagnet includes a battery for excitation, and the switching means is interposed between the battery and the electromagnet.

Further, it is preferable that the electromagnet has an AC power source connecting means, and the switching means is interposed between the AC power source connecting means and the electromagnet.

Further, it is preferable that the permanent magnet is fixed to a bracket which is detachably provided on the cover member.

Further, it is preferable that the magnet is provided on the cover material so as to be located at the back of the filing tool.

Furthermore, it is preferable that the cover material is formed of a sheet having a magnetic shield property folded in two.

The cover material is a member for protecting the sheet, which is used so as to cover both sides of the entire sheet to be bound in the filing tool, or one side of which is used as a backing sheet. It is meant.

The second aspect of the present invention is directed to a magnetic attraction sheet bound to a filing tool. The magnetic attraction sheet is a paper or synthetic resin having a magnetic band attracted and released by the magnet on its side edge. It may be constituted by a sheet such as a sheet. The magnetic band in this case is, for example, a binder (including glue and adhesive) mixed with powder of a soft magnetic material (a material such as a ferromagnetic material that is easily magnetized in a magnetic field and immediately loses magnetism when the magnetic field disappears). Formed by applying and drying on the side edge of the sheet,
Alternatively, it can be formed by attaching a tape made of a soft magnetic material or a tape provided with the magnetic band to the side edge of the sheet.

Such a magnetic attraction sheet is used as a file in combination with the filing tool.

[0022]

In the filing tool according to the first aspect of the present invention, when the magnetic attraction sheets to be bound are placed on the cover material in an aligned manner, the magnetic attraction sheets are attracted by the magnetic attraction means (magnets) of the filing tool and are scattered. It will be caught so that it does not become.

In the case where the magnet is an electromagnet and has a slip resistor or an excitation / demagnetization switching means, when the sheet is bound, the slip resistor or the switching means is demagnetized (or "weak"). ), The magnetic adsorption sheets to be bound are aligned and placed on the cover, and then the slide resistor or switching means is switched to the excitation side (or "strong"). Then, the magnetic attraction sheet is attracted and bound by the magnetic attraction means of the filing tool.

When taking out a sheet, first, the page is repeated while suctioning, and the required sheet is searched. Then, while pinching the sheet with your finger, temporarily move the slide resistor of the magnetic attraction means or the switching means to the demagnetization side (or "weak").
Switch to, and pull out the sheet, then switch to the excitation side (or "strong") again.

As described above, in the file of the present invention, since the magnetic force of the magnetic attraction means is used as the force for binding the sheet regardless of the mechanical engagement of the ring or the tape, it is necessary to make a punch hole. Absent. Further, the switching means does not require a large operating force as compared with the spring type.

When a slide resistor capable of switching magnetic strength is used, when one or several magnetic attraction sheets are extracted, the remaining sheets are magnetically attracted by weak magnetic force. Since it is held by the means, there is an advantage that it does not easily come apart.

[0027]

Embodiments of the file of the present invention will now be described with reference to the drawings.

The filing tool 1 shown in FIG. 1 has a cover 2 in which a gusset (back portion 2a) is removed and folded in half, an electromagnet 3 provided on the back portion 2a of the cover 2, and the electromagnet 3
It is composed of a dry battery 4 for supplying a current to and an ON-OFF switch 5. The electromagnet has a soft magnetic material such as pure iron, silicon steel, other alloys of iron-nickel system, pure iron oxide, etc. having high permeability and little magnetic hysteresis loss as a core, and a coil provided around the core. Is.

Although the ON-OFF switch 5 is provided on the inner surface of the cover 2 in the embodiment shown in FIG.
It may be provided at any position such as the back portion 2a as long as it is convenient for handling.

6 in FIG. 1 is a file to be filed.
Apply adhesive, glue or binder mixed with the powder of the soft magnetic material (for example, iron powder) to the side edge of the sheet 6.
The magnetic attraction sheet is formed by forming the dried magnetic band 7. The magnetic band 7 is a tape made of a soft magnetic material (for example, a tape of metal foil such as silicon steel), or a soft magnetic material powder is adhered to the tape.
It can also be formed by adhering what is mixed with glue or a binder and applied to the side edge of the sheet.

Further, the cover 2 is composed of a magnetic shield sheet for blocking the magnetic force line spreading from the electromagnet 3. As the magnetic shield sheet, pulp paper containing high-permeability metal fiber such as pure iron, synthetic resin sheet in which metal film or metal fiber is laminated or molded, or metal fiber molding used in electric wires is used. Or a shield layer such as a woven material can be used.

When the sheet 6 is bound on the filing tool 1, the switch 5 is turned off to demagnetize the electromagnet 3, the edge of the sheet 6 on the magnetic band 7 side is aligned with the electromagnet 3, and the switch 5 is turned on. To As a result, the magnetic band 7 is magnetically attached to the electromagnet 3, so that the cover 2 is closed and stored.
After that, the back 2a of the cover 2 may be pinched by a tightening mechanism such as a clip or a spring. In this way, the magnetic adsorption sheet will not come apart due to consumption of the dry battery.

The cover 2 may be closed with the switch 5 turned on in advance, and the sheet 6 may be dropped through the gap between the covers 2. In this case, since the magnetic strips 7 of the sheet 6 which have been previously put in have the same polarity, they do not stick to each other. Therefore, it is easy to insert the sheet 6 later.

When the sheet 6 that has been once bound is taken out,
First, the cover 2 is expanded, the switch 5 is turned off, the required sheet 6 is pulled out, and then the switch 5 is turned on again.
Then, the remaining sheet 6 may be closed.

In the embodiment shown in FIG. 1, the ON-OFF switch is used as the switching means, but a switching switch for switching the strength of the voltage applied to the electromagnet may be used. In this case, the strength of the magnetic force can be switched to attach / detach the seat 6. In addition, even if the electromagnet is used in combination with a permanent magnet so that some magnetic force remains even when it is turned off, the strength of magnetic attraction can be switched. In the present embodiment, the electromagnet is supplied with current from a dry battery, but the present invention is not limited to this, and a household AC power supply may be used, for example. In that case, the cover may be provided with a connecting means to the AC power supply, and the AC current may be rectified via a rectifier or the like to supply the current to the electromagnet.
In this case, the strength of the magnetic force can be switched by accommodating a small sliding resistor in the back portion 2a of the cover 2 and adjusting the resistance value.

In the embodiment shown in FIG. 1, the magnetic lines of force converge on the edges of the sheets 6, and all the magnetic bands 7 of the respective sheets 6 are held by the electromagnet 3. Therefore, the holding force of each sheet 6 is large. However, the present invention is not limited to this.

For example, the filing tool 11 shown in FIG.
Has a band-shaped electromagnet 3 slightly inside the back portion 2a of the cover 2. A magnetic force acts on this product through a plurality of sheets 6.

Further, in the file tool 11 shown in FIG. 2, a belt-shaped permanent magnet 12 is provided along the free end of the cover 2. This permanent magnet 12 is for temporarily holding a memo sheet or the like provided with a magnetic band.

The file tool 11 shown in FIG. 3 has a cross-section at both upper and lower ends near the back 2a of the cover 2 so that the back 2a can be covered (solid line) and separated (imaginary line). The ends of the V-shaped brackets 13 and 14 are rotatably provided.

Further, permanent magnets 15 and 16 are housed inside the brackets 13 and 14, respectively. In this case, the brackets 13 and 14 serve as means for performing a function similar to the excitation / demagnetization switching means in the electromagnet type file tool.
That is, when the brackets 13 and 14 are rotated in the directions of the arrows A1 and A2 and brought into contact with the back portion 2a, the seat 6 is adsorbed, which is a so-called excited state, and is rotated and opened in the directions of the arrows B1 and B2. When the time is degaussed. Reference numeral 17 in FIG. 3 is a pin or an eyelet.

As described above, in the case of a filing tool in which the so-called magnetic attraction means is composed of two or more magnets and the excitation / demagnetization can be switched individually, for example, in the upper half as shown in FIG. Sheet 6 with magnetic strip 7a
It is convenient to prepare three types: a, a sheet 6b having the magnetic band 7b in the lower half, and a normal sheet 6 having the magnetic band 7 on the whole. That is, which bracket 1
Since the sheets that can be extracted vary depending on whether the sheets 3 and 14 are opened, there is an advantage that the search can be performed smoothly.

The switching method using the brackets 13 and 14 of FIG. 3 may be applied to the type of FIG. In that case, for example, the form shown in FIG.

On the other hand, also for the filing tools 1 and 11 using the electromagnet 3, the method of switching a plurality of magnetic attraction means in the above embodiment (see FIG. 3) can be applied.
For example, as shown in FIG. 6, above the back portion 2a of the cover 2,
A selection switch for selecting which electromagnet is to be excited by providing three middle and bottom three electromagnets 3a, 3b, 3c
21 should be provided. The number of electromagnets is not particularly limited, and may be two or four or more.

FIG. 7 shows another embodiment of the excitation / demagnetization switching means (or the strength switching means). This one adopts a permanent magnet 22 provided on the back portion 2a of the cover 2 as a magnetic attraction means, and a permanent magnet 2 as a switching means.
The magnetic shield sheet 23 that covers the surface of No. 2 is adopted. The magnetic shield sheet 23 is slidably inserted between the inner surface of the cover 2 and the magnetic permeable sheet (for example, synthetic resin sheet) 25 provided on the inner surface of the back portion 2 a and the cover 2. As a result, when the magnetic shield sheet 23 is inserted in the direction of arrow C, the magnetic force of the permanent magnet 22 is blocked by the end 24 of the magnetic shield sheet 23, and when pulled out in the direction of arrow D, the magnetic force of the permanent magnet 22 acts effectively. .

In this case, one magnetic shield sheet 23 may be adopted, and a plurality of magnetic shield sheets 23 (four sheets in the case of FIG. 7) can be used to select the magnetically bonded portion. You can also

As the permanent magnets used in the files shown in FIGS. 3 and 7, in addition to metal magnets made of magnetic iron or alloy such as KS steel, for example, ferrite powder used for packing for refrigerator doors, etc. A sheet-shaped molded product (so-called rubber magnet) composed of the magnetic powder of (1), a thermoplastic resin, a thermosetting resin, and a binder such as rubber may be used. Furthermore, magnetic powder mixed with a binder is applied to the tape, and this is applied to the bracket 1
The inner surface of 3, 14 (FIG. 3) or the back portion 2a of the cover 2
It may be attached to the inner surface or the outer surface of (FIG. 7).

Furthermore, in the case of the embodiment shown in FIG.
Instead of the brackets 13 and 14, magnetic clips 13a and 14a as shown in FIGS. 11 to 13 may be detachably provided at appropriate positions on the back portion 2a of the cover 2. As the material of the clip, brackets 13 and 1
The same thing as 4 may be used. When using the clip, in order to prevent the clip from easily falling off the cover 2, on the outer surface of the cover 2 near the back portion 2a,
The cross-sectional shape extending along the back portion 2a is approximately C-shaped,
The rail portion 41 having the groove 41a is provided, and the projection 42 having a T-shaped cross section that fits into the groove 41a of the rail portion 41 is clipped.
It is preferable that the inner surfaces of 3a and 14a are provided so as to face each other. For the number of clips,
The number of clips is not limited to two, and three or more clips may be provided on the back portion of the cover 2. Furthermore, the number of clips may be one, but in that case, it is preferable to increase the length of the clip in the width direction as shown in FIG. 14a because the sheet can be bound more reliably.

Although any of the above-mentioned embodiments includes the cover 2 folded in half, the present invention is not limited to such a case, and for example, as shown in FIG. It is also possible to provide the electromagnet 27, the battery 28 and the changeover switch 29.

Each of the magnetic attraction sheets is composed of one sheet, but as shown in FIG. 9, a sheet 30 folded in two and two or more sheets 31 are stapled (stitched) 32. The sheet bound with may be used as the magnetic adsorption sheet. In the latter case, the staple 32 plays the same role as the magnetic band.

In the embodiment of FIGS. 3 and 5, the bracket 1
The pins 3 and 14 are rotatably provided with respect to the cover 2 by a pin 17, but the brackets 13 and 14 are fixed to the back portion 2a by parallel link mechanisms 18 and 19 as shown in FIG.
