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, flipping the bound paper sheets and returning them to their original positions even if the hand is removed from the paper sheets. The present invention relates to a paper clip that is sandwiched so that it can be held in a flipped state.

[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, since the clip of the wire sandwiches the paper sheet between the two ring-shaped portions formed by bending the wire doubly, if the elasticity of the wire is weak, the paper clip easily separates. 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 when binding thin paper sheets having a relatively small number of sheets, and the clip using a leaf spring is used when 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 are knobs made of metal wire to widen the abutting end parts. Each of them is rotatably attached, and after turning the middle part of these knobs so as to hit the corner of the leaf spring, the two free ends of the knobs are pinched by the fingers so that they come into contact with each other. It was designed to spread.

[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 the above circumstances, and its object is to be able to firmly bind a plurality of paper sheets with a strong spring property, and to flip the bound paper sheets, It is an object of the present invention to provide a paper sheet clip that can hold a flipped state without returning to the original even when the paper sheet is released.

[0006]

In order to solve the above-mentioned problems, the first means is a paper sheet clip made of a metal plate-like body, and an upper plate portion having a substantially right triangle, 3 of a lower plate part having a larger area than the upper plate part, and a side plate part connecting one side forming a right angle part of the upper plate part and one side of the lower plate part
It is characterized in that it has two plate portions, and that the side plate portion is formed with an arcuate recess so that the free ends of the upper plate portion and the lower plate portion elastically contact each other.

The second means is characterized in that the lower plate portion in the first means is also formed into a substantially right-angled triangle, and one side forming the right-angled portion is connected to the side plate portion.

A third means is characterized in that an upper inclined portion which is inclined obliquely upward is formed on the inclined side of the upper plate portion in the first means.

The fourth means is characterized in that an opening for weakening the elasticity of this portion is formed at the free end portion of the lower plate portion of the second means facing the side plate portion side.

The fifth means is that the lower plate portion in the first means is made substantially rectangular and the corner portion abutting the free end portion of the upper plate portion facing the side plate portion side is cut out. It has a feature.

The sixth means is characterized in that a lower inclined portion which is inclined obliquely downward is formed on the peripheral edge of the cutout portion of the corner portion of the fifth means.

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. In addition,
Throughout the respective embodiments, substantially the same constituent elements are designated by the same reference numerals, and a duplicate description will be omitted.

First, a first embodiment of the present invention will be described with reference to FIGS. 1 is a perspective view showing the first embodiment of the bear, FIG. 2 is a plan view thereof, FIG. 3 is a side view seen from the left side of FIG. 2, and FIG. 4 is a bottom view seen from below in FIG. 5 is a perspective view showing the usage state.

The paper clip 1 according to the first embodiment
Is a right-angled triangle of an upper plate portion 2 having a substantially right-angled triangle, and a substantially right-angled triangular shape similar to the upper plate portion 2, and a size of the lower plate portion 3 which is larger than the upper plate portion 2 and the upper plate portion 2. It is composed of three plate-like portions of the side plate portion 4 which connects one side forming the right side portion of the lower plate portion 3 and one side forming the right angle portion of the lower plate portion 3. The paper clip 1 is formed by punching a metal plate having elasticity such as an iron plate or a stainless steel plate with a press machine and bending the metal plate to integrally form three plate-shaped portions. Side plate part 4
Sets the thickness at which the paper clip 1 can be bound and has an arcuate recess. Due to this recess, an elastic force is generated so that the inclined sides 5 and 6 of the upper plate portion 2 and the lower plate portion 3 elastically overlap each other.

On the inclined side 5 of the upper plate portion 2, an upper inclined portion 7 which is inclined slightly obliquely upward is formed by pressing or the like. The upper inclined portion 7 is a side edge 8 that is substantially perpendicular to the side plate portion 4.
It also extends to the side. As a result, a gap 9 is formed between the lower plate portion 3 and the inclined side 5 of the upper plate portion 2 which is elastically pressed onto the lower plate portion 3. Inclined side 6 of lower plate part 3
And a corner 12 where a side edge 11 that is substantially perpendicular to the side plate 4 intersects
An opening 13 is formed in the. The opening 13 makes it easier to bend by reducing the area of the corner portion 12, and makes it easier to open between the same corner portion 14 of the upper plate portion 2 located above.

When a plurality of paper sheets 15 are bound by the paper sheet clip 1 thus constructed, the corner portion 1 of the lower plate portion 3 is bound.
While applying the upper edge of the paper sheet 15 to the sheet 2, and inserting the paper sheet 15 into the gap 9, a force is applied to raise the entire paper sheet clip 1 upward. As a result, a gap is formed between the corner 12 and the corner 14 of the upper plate 2. The paper sheet 15 is pushed through the gap to slide the paper sheet 15 between the upper plate portion 2 and the lower plate portion 3. Since the paper leaf clip 1 is made of a metal plate, the paper leaf 15 sandwiched between the upper plate portion 2 and the lower plate portion 3 can be slid without being scratched. Further, even when the paper sheet 15 is sandwiched, the side plate portion 4 can be slid with a little strong force while being slid between the fingers. Therefore, after pushing the upper edge of the paper sheet 15 until it hits the side plate portion 4, as shown in FIG. Align with the left edge of the.
Thereby, as shown in FIG. 5, the paper sheet clip 1 is located at the upper left corner of the paper sheet 15, and the inclined side 5 of the upper plate portion 2 is located so as to diagonally cross the corner portion of the paper sheet 15. .

As a result, the paper sheet 15 can be turned up diagonally upward as shown in FIG. Since the corners of the paper sheet 15 are clamped, the paper sheet 15 can be turned up greatly and is not turned over by the weight of the turned-up paper sheet 15. Further, since the bent portion of the paper sheet 15 is held by the upper inclined portion 7, there is no crease in the portion that abuts the inclined side 5. Since the upper plate portion 2 and the lower plate portion 3 of the paper sheet clip 1 are pressed against each other with a strong elastic force by the radius of the side plate portion 4, it is possible to firmly sandwich a plurality of paper sheets 15 and turn them. There is no chance of falling apart while you are there.

Next, a second embodiment will be described with reference to FIGS. 6 to 10. 6 is a perspective view showing the second embodiment, FIG. 2 is a plan view thereof, FIG. 3 is a side view seen from the left side of FIG. 2, FIG. 4 is a bottom view seen from below in FIG. [Fig. 3] is a perspective view showing its usage state.

In the paper clip 21 according to the second embodiment, the lower plate portion 3 according to the first embodiment is replaced with a substantially rectangular lower plate portion 22 in order to make it easier to insert the paper sheet 15. I am configuring. The shape of the lower plate portion 22 will be described in detail. The corner portion that is substantially rectangular and has a side edge 23 that faces the side edge 8 of the upper plate portion 2 and an end edge 24 that faces the side plate portion 4 intersects each other. A circular notch 25 is formed. As a result, the upper plate portion 2 has the inclined side 5 on the lower plate portion 22.
Will be located diagonally across. Notch 25
In the upper plate portion 2, a lower inclined portion 26 that is inclined in the opposite direction to the upper inclined portion 7 of the upper plate portion 2 is formed by pressing or the like.
A gap 27 (FIG. 9) is formed at a portion where the cutout portion 25 and the cutout portion 25 intersect with each other so as to form a catch when the paper sheet 15 is inserted. The other configuration is the same as that of the first embodiment described above.

In the second embodiment, when binding thin paper sheets 15, a gap formed by the flat plate-like lower plate portion 22 and the upper inclined portion 7 of the upper plate portion 2 located thereabove. It is inserted between the upper plate portion 2 and the lower plate portion 22, and is slid so that the side edge 8 is located at the left edge of the paper sheet 15, as in the first embodiment. This allows
As shown in FIG. 10, the paper clip 21 is located at the left corner of the paper 15, and the inclined side 5 of the upper plate 2 is located so as to cross the corner of the paper 15 diagonally.

On the other hand, when the number of paper sheets 15 increases or the paper sheets 15 become thick and cannot be inserted into the gap between the lower plate portion 22 and the upper inclined portion 7 of the upper plate portion 2, The corner portion 14 of the plate portion 2 is applied to the upper surface of the paper sheet 15, the lower surface of the paper sheet 15 is placed on the exposed lower plate portion 22, and the paper sheet clip 21 is twisted so as to lift the lower plate portion 22 side. Then, the space between the corner portion 14 of the upper plate portion 2 and the lower inclined portion 26 is widened, and the upper edge of the paper sheet 15 may be inserted through the widened gap. This expansion is to push up the corner portion 14 of the upper plate portion 2. Since this portion is thin, it can be performed by applying a slight force, and the paper sheet 15 can be very easily formed.
Can be bound.
