Description

Paper clip

The present invention relates to a clip for fixing a plurality of sheets of paper, and more particularly, to a paper clip for pressing and opening the ends that are in contact with each other by two handles, and fixing a plurality of sheets of paper between the ends.

In the case of collecting a sheet of paper, a clip called a double clip is conventionally used widely. The clip forms a contact portion having a thickness almost equal to the maximum iron thickness at the center portion, bends both ends in the same direction from each other and elastically contacts the both ends. It consists of a main body made of an elastic plate, such as a strip-shaped steel, and two handles made of hard metal wires rotatably inserted at both ends, respectively, in a locking portion formed by bending an end of each of the contact portions in a ring shape. When the paper is fixed together, the free end sides of the two handles are rotated to the distribution side, and the free end sides of the two handles are brought into contact with each other by pressing them, and the pressing ends of the contact portions are widened. It is supposed to be inserted.

The portion where the document or the like in this clip is substantially sandwiched is the edge of the pair of contact portions of the main body, and the length of the edge portion corresponds to the width of the elastic plate, that is, the width orthogonal to the thickness direction of the back portion. . Moreover, the elastic force which acts so that the edges of two contact parts may contact each other is generate | occur | produced by bending the boundary part of a back part and a pair of contact part, and contacting the edge part of a contact part elastically. When the clip body is viewed from the side, the thickness direction of the back is made the bottom side, and the remaining two sides constitute a isosceles triangle which is a contact portion of the same length. In this case, only by bending the two boundary portions so that the edge portions of the contact portions come into contact with each other, the whole edge portions of the contact portions do not certainly come into contact with each other, and two or three thin sheets of paper cannot be firmly fixed. In addition, the gripping force is also weak and thick paper cannot be sandwiched. Therefore, the inside angle of each boundary is made an acute angle by curving | distributing a back so that it may protrude in the edge edge direction along the width. By making the acute angle, the virtual intersection point at the two edges of the contact portion moves to the center of the triangle, and the edges of the contact portions closely contact each other, so that the thin paper can be firmly fixed, and the gripping force is increased, so that the thick paper can be secured. Can be fixed. So, for example, originally two bilateral triangles of which the inner angles of the boundary are about 65 °, but as described above, the inner angle is about 40 ° by bending the back so that a strong elastic force is applied between the two edges of the contact portions. Occurs on. This cabinet varies depending on the size of the clip, but in order to form an isosceles triangle from the side, two bend angles of the boundary, that is, the cabinet angle, must be 90 ° or less.

On the other hand, in Japanese Utility Model Laid-Open Publication No. Hei 6-79580 or Utility Model Laid-Open Publication No. 7-31374, an opening is formed almost in the center of the back of the clip as described above, and the edge of the paper to be fixed in the opening is formed. The so-called corner clip which protrudes outward and makes it easy to fix the edge of paper is proposed. In addition, Japanese Patent Laid-Open Publication No. Hei 8-25866 has an improved version of the corner clip of Utility Model Publication No. Hei 7-31374, and the edge of the opening is set to the boundary between the back and the contact portion, thereby forming an opening. This prevents opening between the edges of the contacts.

As described above, the conventional clip generates an elastic force in which the end edges of the contact portions come into contact with each other by bending two portions of the boundary portion between the back portion and the contact portion. It is to strengthen the elastic force to the back of the. For this reason, strong elastic force is generated between the edges of the contact portions in contact with each other more than necessary, and in order to fix the paper having a thickness close to the maximum thickness allowed by the clip, it is not easy to press and widen the contact portions in parallel with each other. In particular, very large force is required for large clips. In addition, when the paper is fixed, a strong gripping force is applied to the paper so that the paper is not pulled out even if a strong shock is applied from the clip portion, and when the clip is removed, the marks by the edges of the contact portion are removed. It may occur on paper.

However, when stiff paper is removed, it is rarely used to apply a strong shock to the paper by holding a finger on the handle of the clip or by applying a strong shock to the paper while holding the finger on the handle of the clip. It is desired to be able to easily open the edge with weak force. The elastic force is somewhat stronger if the inner angle is an acute angle, but in this case, when the inner angle of the boundary portion is enlarged, the elastic force can be reduced. However, when opening between the edges of the contact portion, it becomes wider than the cabinet, and if it is repeated several times, deformation occurs, and after fixing the thick paper for a long time, removing the clip, there is a gap between the edges of the contact portion, Attempting to fix a thin sheet of paper on the paper may cause the paper to detach easily.

In the corner clips described in the above-mentioned Utility Model Publication No. Hei 6-79580 or Utility Model Publication No. Hei 7-31374, an opening is provided in the back, but the elastic force is not lowered simply by providing the opening in the back. On the contrary, in Japanese Patent Application Laid-Open No. Hei 8-25866, when only the portion of the opening is deleted, the boundary between the distribution portion and the contact portion is reduced, and the elastic force is also lowered. In order to prevent this, it is described that the opening reaches the boundary between the back portion and the contact portion. Therefore, the opening of the back is only for protruding the edge of the paper, and by providing the opening, it is not intended to lower the elastic force so that it can be easily opened almost parallel between the contact portions.

The present invention has been made in view of the situation of the prior art, and its first object is to allow the opening operation to be performed with a much weaker force than before, and the paper clip with less deformation even if the sheet-like member close to the maximum iron thickness is fixed. To provide.

The second object of the present invention is to fix all the sheet-like members having a thickness close to the maximum iron thickness even with a metal plate having a low spring characteristic, and even if the sheet-like member is removed, the contact portion is returned to come into close contact, To provide a clip that can be used repeatedly.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described with reference to drawings. In addition, in each following embodiment, each part which can be considered equivalent is attached | subjected with the same reference number, and the overlapping description is abbreviate | omitted suitably.

First, the first embodiment shown in Figs. 1 to 5 will be described. 1 is a perspective view showing a clip of the first embodiment, FIG. 2 is a plan view thereof, FIG. 3 is a bottom view of the first clip, FIG. 4 is a side view of the first clip, and FIG. 5 is a clip of the first embodiment. It is a perspective view which shows the fixed state.

The clip 11 is comprised from the main body 14 which bend | folded the metal strip | belt-shaped board | plate material, such as steel and stainless steel, and the handle 25 made of hard metal wire. The main body 14 has a width almost equal to the maximum iron thickness, and has a trapezoidal back portion 12 having a flattened vertex portion near the center and protruding outwardly, and both ends in the longitudinal direction from the back portion 12. Is bent in the same direction, and a pair of contact portions 13 in which both ends are elastically contacted are formed by bending or the like. On both sides of the edge portion of the contact portion 13, locking portions 15 formed by bending in a ring shape are formed, respectively, and the edge edges 16 of the contact portions 13 positioned between these locking portions 15 are also conventional. It is bent like this kind of clip.

In the first embodiment, four bent portions are formed in order to impart an elastic force to each of the contact portions 13 so that the edges of the respective contact portions 13 contact each other. That is, the first and second bent portions 17 and 18 formed at the boundary portion between the width direction both ends of the back portion 12 and the contact portions 13 subsequent thereto, the flat vertex portion of the back portion 12 and the apex portion, respectively. The third and fourth bent portions (19, 21) formed in the boundary portion with the inclined sides on both sides subsequent to the contact portion (13) are formed. Each of these internal angles α1 and β1 is composed of angles larger than 90 °. In addition, as shown in detail in FIG. 4, the respective inner angles α1 formed by the first and second bent portions 17 and 18 are formed by the third and fourth bent portions 19 and 21. It is configured to be an acute angle than the respective inner angle β1, the elastic force by the first and second bent portions (17, 18) is set to be strong, the elastic force by the third and fourth bent portions (19, 21) is set to be weak have. Moreover, the opening 22 is drilled in the substantially center part of the back part 12 of the main body 14. As shown in FIG. In the center of the back 12 side of each contact portion 13, a cut portion 23 is formed to be connected to the opening 22, respectively.

Both end portions of the handle 25 made of hard metal wires are rotatably inserted into the locking portions 15 of the contact portions 13, respectively. The handle 25 is composed of a handle main body 26 with a central portion bent almost in a cup shape, and two ends 27 formed by bending both ends of the handle main body 26 at approximately right angles. ) Both end portions 27) of both sides 27 are inserted into the two locking portions 15 of the contact portion 13 on one surface side, and both ends 27 of the other handle 25 are contact portions 13 on the other surface side. ) Into both locking portions 15). The gap between the opposite leg portions of each handle main body 26 is wider than the width of the opening 22 extending in the longitudinal direction of the back 12, and as shown in FIG. When the free end side is rotated toward the back 12 side, the handle main body 26 touches the outer surfaces of the first and second bent portions 17 and 18 so that this portion is a support point of the handle 25. Consists of.

When fixing the several sheets of document 10 which are sheet-like members by the clip 11 comprised as mentioned above, as shown in FIG. 1, the free end side of the handle main-body part 26 is rotated to the distribution 12 side. By moving, the center part of the handle main body 26 is brought into contact with the edges of the back 12 and the contact part 13, and the free end of the two handle main body parts 26 is grasped with a finger, and the back 12 and the contact part are carried out. It is good to make the contact part 13 of the main body 14 wider by the edge part 27 side of the handle main-body part 26, and to put a document in between. In addition, when fixing the edge of the document 10, as shown in Figure 5, the edge of the document 10 is inserted into the clip 11 so as to protrude from the opening 22, the end of the contact portion 13 Insert the paper from the edge. By providing the opening 22, the end edge of the contact portion 13 can deepen the pressing position from the corner vertex of the document 10 as compared to this kind of clip of the prior art, and is always inserted even if the thick document is turned over. I can definitely keep it. In addition, since the cutout portions 23 connected to the openings 22 are formed at substantially the center of the back 12 side of each contact portion 13, the exposed portions of the corners of the document 10 can be increased. In this way, it is possible to more surely observe that the edge of the document 10 is fixed by the clip 11.

Moreover, since the back part 12 is substantially trapezoidal, and the whole clip forms a pentagon, each inner angle (alpha, 1, beta 1) has the edge of the contact part 13 mutually, even if it is an angle larger than 90 degrees. It can be in intimate contact and can make the elastic force weaker than the conventional clip. In addition, each of the internal angles β1 constituting the third and fourth bent portions 19 and 21 is formed at an obtuse angle than the internal angles α1 constituting the first and second bent portions 17 and 18 to form a third angle. And a strong elastic force such that the end edges of the contact portions 13 are brought into contact with each other by the fourth bent portions 19 and 21, and the third and fourth bent portions are formed by the first and second bent portions 17 and 18. It is weaker than the portions 19 and 21, but more firmly provides an elastic force so that each contact portion 13 is in contact with each other. Thus, one contact portion 13 has a two-stage elastic force by the first and third bent portions 17, 19, and the other contact portion 13 has second and fourth bent portions 18, 21. The elastic force of the two stages by () is given, respectively, and when opening the contact portion 13, the maximum iron thickness regulated by the thickness of the back portion 12, even if the bent portions 17, 18, 19, 21 are not completely opened, respectively. It is possible to form a gap sufficient to sandwich the sheet-like document 10 nested to almost the same thickness. In addition, the first and second bent portions 17 and 18 allow the end edge of the contact portion 13 to have a soft elastic force and to press the surface of the sheet-like document 10, without the wounding. (10) can be inserted.

In addition, by providing the opening 22 and the cut portion 23, the elastic force acting to bring the two contact portions 13 into contact with each other is weaker than when the opening 22 or the cut portion 23 is not provided. The force of holding the free ends of the two handle main body parts 26 with the fingers and pressing them between the contact parts 13 may be small. On the other hand, since the widthwise length of the end portion of the contact portion 13, ie, the latching portion 15 side, on which the document is to be inserted is not different from the conventional one, the document is reduced due to the decrease in the elastic force by the opening 22 or the cut portion 23. Although the force for clamping the pin becomes small, the document does not come off from the clip 11 even if it is flipped over, and sufficient force can be exerted to hold the document.

As described above, in order to sandwich the sheet-like document 10 stacked to a thickness substantially equal to the maximum iron thickness, even if the contact portions 13 are opened so that the contact portions 13 are positioned substantially in parallel, each bent portion 17 , 18, 19, 21 are opened with a margin, so that each bent portion is not deformed. Even if the contact portion 13 is opened to the maximum, each bending portion is not deformed, and upon release of the spreading force, the original elastic force can be immediately given, and the sheet-like document 10 of approximately the same thickness is sandwiched at the maximum iron thickness. Even if it is removed later, the end edges of the contact portions 13 of the clip 11 again reliably contact each other, and no gap is formed therebetween. Thus, the paper clip without deformation can be made of stainless steel having a lower elasticity than steel but easy post-treatment, and can be provided at low cost. The body 14 of the clip 11 may be made of steel as in the prior art, or may be made of an elastic metal plate such as phosphor bronze. In addition, in this 1st Embodiment, all the internal angles (alpha) 1 are about 95 degrees, and all internal angles (beta) 1 are about 155 degrees.

Next, 2nd Embodiment shown in FIG. 6 and FIG. 7 is demonstrated. 6 is a perspective view showing a clip of a second embodiment, and FIG. 7 is a side view thereof. In the clip 31 according to the second embodiment, a bent portion for applying an elastic force to each of the contact portions 13 so that the edges of the contact portions 13 contact each other, as in the first embodiment, Each of the first and second bent portions 32, 33 and the first and second bent portions 32, 33, which are formed at the boundary between the both ends and the contact portions 13 that follow each other, are spaced at equal intervals, respectively. It consists of four bending parts of the 3rd and 4th bending parts 34 and 35 formed in the contact part. In addition, in this 2nd Embodiment, as shown in detail in FIG. 7, the height of the trapezoid part of the back part 12 is higher than 1st Embodiment mentioned above.

In addition, also in 2nd Embodiment, each internal angle (alpha) 2 of the 1st and 2nd bending parts 32 and 33 was set as the 3rd and 4th bending parts 34 and 35 similarly to the said 1st Embodiment. Although it is comprised so that it may become acute angle | corner than the cabinet (beta) 2, the cabinet (alpha) 2 is set to an obtuse angle than the cabinet (alpha) 1 of the said 1st Embodiment, and, on the contrary, the cabinet (beta) 2 is acute than the cabinet (beta) 1 of the said 1st Embodiment. I am doing it. In this case, in order to prevent the angle of each internal angle (beta) 2 becoming too large, and the function which gives elastic force declines, between the 1st bend part 32 and the 1st bend part 32 between the edges of the contact part 13, And the four portions between the third bent portion 34, the end portion of the contact portion 13, the second bent portion 33, and the second bent portion 33 and the fourth bent portion 35, respectively. It is curved in an arc shape projecting inward. Although not shown in the drawings, the third and fourth bent portions 34 and 35 may also be formed in an arc shape.

As in the second embodiment, each contact portion 13 by the first and second bent portions 32 and 33 is formed by setting the inner angle α2 of the first and second bent portions 32 and 33 to an acute angle. The elastic force for the edges of the edges to mutually contact each other becomes strong, and the gripping force on the paper becomes strong. On the other hand, by increasing the internal angles β2 of the third and fourth bent portions 34 and 35, the elastic force by the third and fourth bent portions 34 and 35 at the edges of the respective contact portions 13 is increased. Is weaker than in the first embodiment, and the contact of the edges of the respective contact portions 13 to the paper can be smoothed. In this 2nd Embodiment, all the internal angles (alpha) 2 are about 110 degrees, and all internal angles (beta) 2 are about 130 degrees.

As apparent from the above description, according to the invention of claim 1, at least three bent portions are formed in order to impart an elastic force to the contact portion. When each bent portion is required to have an elastic force of one-hundredth of the bent portion, and each bent portion is bent such that almost one-elastic force of the bent portion is generated, the widths are substantially parallel to each contact portion. Even when a force is applied, each bent portion is widened with a margin, so that no deformation occurs in each bent portion. In addition, since the opening is formed in the back, when the corners of the paper are fixed, by inserting the corners of the paper into the openings, the pressing position from the corner apex of the paper can be positioned deeper than a conventional clip. , You can press the edge firmly. In addition, since the opening extends into the contact portion adjacent to the opening, the exposed portion of the edge of the paper can be enlarged, and the edge of the paper can be reliably observed by the clip.

According to the invention of claim 2, there are two bent portions formed at intervals almost at the center of the belly, and a total of four bent portions formed at the boundary between the both ends of the belly and each contact portion subsequent thereto. Because of this, the elastic forces can be dispersed into four, and even if a widening force is applied to them in parallel with each contact portion, each bent portion can be widened with more margin, and the occurrence of deformation in the bent portion is also achieved. More certainly can be suppressed.

According to the invention of claim 3, since the inner angle of each of the first to fourth bent portions is set at an angle greater than the right angle, the elastic force for contacting each other is weaker than that of the conventional clip, and the contact portion can be operated with weak force. It can be easily opened between the edges.

According to the invention of claim 4, each cabinet constituting the third and fourth bent portions is an obtuse angle than the cabinet angles constituting the first and second bent portions, whereby the end edge of the contact portion has a soft elastic force and is iron It can be pressed without damaging the surface of the sheet-like member to be made.

According to the invention of claim 5, since at least a part of the sides constituting the trapezoid is curved inward, the inner angle of each bent portion can be formed at an acute angle, and even if the height of the trapezoid is increased, it can have the necessary elastic force. .

According to the invention of claim 6, the gripping force to hold the paper can be set by adjusting the angles of the inner angles of the third and fourth bent portions, so that even a metal plate having the same sheet thickness can provide a clip having different gripping forces. .

According to the invention of claim 7, the pair of leg portions of each handle face each other at a distance wider than the width of the opening so that at least portions contacting the edges of the back portion face each other. The contact part can be surely opened, and the contact part can be surely opened.

According to the invention of claim 8, since the metal plate is made of stainless steel, it is resistant to corrosion and can be shipped as a product without performing surface treatment such as plating, and can be provided at low cost.
