Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for sandwiching and binding a plurality of paper sheets, and more specifically, it is formed by bending a single elastic metal plate and is bound by only fingers. It is related to paper leaf cribs.

[0002]

2. Description of the Related Art When a plurality of paper sheets are put together, it is widely used to insert a wire into a bent clip. However, the clip of the wire sandwiches the paper sheet between the two ring-shaped parts formed by bending the wire doubly, so if the elasticity of the wire is weak, it will easily come apart, and if the elasticity of the wire is increased, It is difficult to open between the two ring-shaped parts,
Further, there is a defect that ring-shaped convex portions or concave portions are formed on the paper sheet. Further, the biggest drawback is that the spring elasticity is weak due to the wire, and when trying to sandwich a large number of sheets, the gap between the double rings is easily expanded and the sheets cannot be bound. Therefore, the clip of the wire is used for binding thin paper sheets having a relatively small number of sheets, and a clip using a leaf spring is used for binding a large number of sheets of thick paper.

A leaf spring clip using this leaf spring is
Bend a rectangular leaf spring into a substantially triangular shape when viewed from the side, widen the abutting end parts, and put the use between them, and there is a knob made of metal wire to widen the abutting end parts. Each of the leaf springs is rotatably attached, and is rotated so that the middle portion of these knobs contacts the corner portion of the leaf spring, and then the two leaf springs are brought into contact by pinching them with fingers so that the free end sides of the two knobs come close to each other. It is designed to widen between both ends.

[0004]

The above leaf spring clip has a stronger gripping force than the former wire clip and can firmly bind the paper sheets, but the knob is an obstacle.
If the two knobs are positioned so that their free ends contact each other, it will be an obstacle to flipping the paper sheet. On the contrary, when the free ends of the two knobs are rotated in a direction away from each other, the flipped paper sheet hits the knob and returns the paper sheet. Therefore, this leaf spring clip is convenient for binding sheets, but inconvenient for flipping the sheets in the bound state.

The present invention has been made in view of such a situation as described above, and a problem thereof is that a single metal plate can be extremely easily prepared by press working or the like, and a plurality of paper sheets can be easily formed. It is an object of the present invention to provide a paper clip capable of firmly binding leaves with a strong spring property.

[0006]

In order to solve the above-mentioned problems, the first means is a paper sheet clip made of a metal plate-like member, and a substantially rectangular side portion and a relative portion of this side portion. Has two holding parts that extend in the same direction from each other in the same direction and that holds the paper sheet therebetween, and each holding part is adjacent to the side part, and its tip is the other holding part. A bent portion that is bent so as to come closer to, and an abutting portion that has a substantially right-angled triangle in which one side is located at the tip edge of this bent portion and an inclined edge is located from one end to the other end of this tip edge. And each of the two inclined edges are located so as to intersect with each other.

The second means is characterized in that the edge portions of the inclined edges in the first means are bent in directions away from each other.

The third means is characterized in that each contact portion in the first means is bent from the boundary with the bent portion so as to be substantially parallel to each other.

The fourth means is characterized in that the side portion of the first means is curved in an arc shape so as to be elastically biased in a direction in which the tips of the two bent portions come into contact with each other.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a paper clip according to the present invention will be described below with reference to the drawings. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a plan view thereof,
3 is a cross-sectional view taken along the line AA in FIG. 2, FIG. 4 is a side view, FIG. 5 is a bottom view seen from below in FIG. 2, and FIG. FIG. 7 is a perspective view showing a folded state, and FIG. 7 is a perspective view showing a state in which a part of the bound paper sheets is opened.

The paper clip 1 has a substantially rectangular side portion 2.
And two holding portions 3 and 4 extending in the same direction from both side edges of the side portion in the longitudinal direction and holding the paper sheet therebetween. This paper clip 1
An elastic metal plate such as an iron plate or a stainless steel plate is punched by a press machine and bent to form one side portion 2 and two sandwiching portions 3 and 4 in a total of three portions integrally. There is. The side portion 2 sets a thickness at which the paper sheet clip 1 can be bound and has an arcuate recess. Due to this recess, the two holding parts 3, 4
Generate elastically overlapping forces.

The holding portion 3 is adjacent to the longitudinal end edge of the side portion 2, and the bent portion 5 is bent so that its tip approaches the other holding portion 4, and the tip edge of the bent portion 5. Has a contact portion 7 in the shape of a substantially right triangle in which one side is located and the inclined edge 6 is located from one end to the other end. Similarly, the other holding portion 4 is also adjacent to the other longitudinal edge of the side portion 2, and the bent portion 8 is bent so that its tip approaches the holding portion 3, and the tip of this bent portion 8. It has a contact portion 10 in the shape of a substantially right triangle, one side of which is located in green, and the inclined edge 9 is located from one end to the other end of the tip edge. These two contact portions 7 and 10 are bent from a boundary portion 11 with the bent portions 5 and 8 so that their surfaces face each other substantially in parallel. Furthermore, the two contact portions 7, 10
Are arranged such that their inclined edges 6, 9 intersect each other. The slanted edges 6.9 are bent by press working or the like so as to be slanted in mutually opposite directions.
A gap 12 is formed between the sheets 9 to serve as a mouth for sandwiching the paper sheet. The gap 12 becomes a large gap by increasing the bending angle of each of the slanted edges 6 and 9, and is suitable for binding a large number of sheets or binding a sheet whose overall thickness is thick due to a thick sheet or the like. is there. In addition, in order to prevent the leading edge of the contact portions 7 and 10 from scratching the flipped sheet,
It is cut so as to be substantially parallel to the boundary portion 11, and the cut edge portion is also chamfered.

When binding a plurality of paper sheets 13 with the paper clip 1 thus constructed, the lower surface of the contact portion 7 is brought into contact with the upper surface of the uppermost paper sheet, and the upper surface of the contact portion 10 is moved to the uppermost position. The paper sheet 13 is inserted between the abutting portions 7 and 10 so as to contact the lower surface of the lower paper sheet. As a result, the upper edge of the paper sheet 13 enters the gap 12 formed between the slanted edges 6 and 9, and in that state, the paper sheet clip 1 is pushed in while slightly twisting so as to lift the contact portion 10 side. Go out. Due to this twist, the gap 12 between the inclined edges 6 and 9 is inserted into the paper sheet 1.
Since the space between the contact portions 7 and 10 is widened by 3, the paper sheet 1
3 can be pushed between the contact portions 7 and 10 without difficulty. Since the paper sheet clip 1 is made of a metal plate, the paper sheet 13 sandwiched between the contact portions 7 and 10 can be slid without being scratched, and the upper edge of the paper sheet 13 can be easily Can be pushed so that it hits the side part 2. Further, since the side portion 2 can be slid with the fingers even when the paper sheet 13 is clamped, the paper sheet clip 1 can be slid to a desired position after the paper sheet clip 1 is appropriately inserted. .

Therefore, after pushing the upper edge of the paper sheet 13 until it hits the side portion 2, as shown in FIG. 6, if the paper sheet clip 1 is shifted to the left side of the upper edge of the paper sheet 15, the left side of the paper sheet 13 will be left. It can also be used as a corner clip that holds down corners. In this case, the inclined edge 6 of the contact portion 7 is positioned so as to diagonally cross the upper left corner of the paper sheet 13, and thus the paper sheet 13
As shown in FIG. 7, the slanted edge 6 can be used as a guide to turn up diagonally upward. Since the corners of the paper sheet 13 are clamped, the paper sheet 13 can be turned up greatly, and is not turned over by the weight of the turned-up paper sheet 13. Further, since the slanted edge 6 is slanted upward, the paper sheet 1
Since the bent portion of 3 is held so as to draw an arc, there is no crease in the portion that contacts the inclined edge 6. The abutment portions 7 and 10 of the paper clip 1 are rounded by the side portion 2,
Since the elastic forces that are pressed against each other are formed by the strong elastic force, the plurality of paper sheets 13 can be firmly sandwiched and do not come apart during the flipping.

When removing the paper clip 1, the side portion 2 can be easily removed by grasping the side portion 2 with a finger and can be repeatedly used.

In the above-described embodiment, the tips of the abutting portions 7 and 10 are cut so as not to damage the flipped sheet 13, but these tips are rounded so as not to form an acute angle. You may cut so as to attach.

[0017]

As is apparent from the above description, substantially rectangular side portions and two holding portions that extend in the same direction from the opposite edges of the side portions and hold the paper sheet therebetween. , Each of the sandwiching parts is adjacent to the side part, and the bent part is bent so that its tip approaches the other sandwiching part, and one side is located at the tip edge of this bent part, The invention according to claim 1, further comprising a contact portion having a substantially right triangle in which an inclined edge is located from one end to the other end of the tip edge, and the two inclined edges are positioned so as to intersect each other. According to this, the paper sheet can be inserted between the abutting portions by inserting the abutting portion between the two abutting portions and pushing the abutting portion located below the paper sheet while twisting the abutting portion so as to lift the abutting portion. You can bind paper with strength. If you pull it out with your fingers, you can easily remove it for repeated use.

According to the invention as claimed in claim 2, wherein the end edge portions of the respective inclined edges are bent in directions away from each other, a gap is formed between the opposite inclined edges, and the gap forms a gap for sandwiching the paper sheet. The paper sheet can be easily and smoothly held.

According to the invention of claim 3, wherein the contact portions are respectively bent from the boundary with the folded portion so as to be substantially parallel to each other, when the paper sheets are bound, the contact portions are on the surface of the paper sheet. They can be brought into surface contact with each other, and the paper sheet can be held more reliably.

According to the invention of claim 4, the side portions are curved in an arc shape so as to elastically deviate in the direction in which the tips of the two bent portions contact each other. A strong elastic force can be imparted to the sheet and the sheet can be firmly sandwiched.
