DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip, and more particularly to a clip for holding a document or the like.

[0002]

2. Description of the Related Art Heretofore, various clips have been proposed and put into practical use.
For example, as shown in FIG. 1 of JP-A-2000-37980, one end of a first support piece and one end of a second support piece facing each other are connected by a connection piece so as to have a substantially U-shaped cross section. The free end side of the second support piece is extended through a hinge groove to form a pressing piece, and this pressing piece is folded back from the hinge groove and its tip abuts on the inner surface of the first support piece. There is a known configuration.

[0003]

However, the above-mentioned clip has a pressing piece formed by folding back through a hinge groove, and has a low elastic restoring force. Even when a document or the like is inserted, the pressing force against the clip is small. It is weak, and when pulling out documents etc., the contact friction between the holding piece and the documents etc. is small,
For this reason, there has been a problem that documents and the like are likely to slip out.

[0004] It is an object of the present invention to solve the above-mentioned problems and to propose a clip having a particularly simple structure and capable of securely holding a document or the like.

[0005]

In order to solve the above-mentioned problems, a clip according to the present invention connects one end of a first support piece and one end of a second support piece facing each other via a connection portion,
A pressing piece bent into a V-shape is formed from the other end of the first supporting piece, and a document is inserted between the outer surface of the pressing piece and the inner surface of the second supporting piece so as to be sandwiched therebetween. An engaging claw that engages with the surface of the document is formed on the inner surface of the supporting piece on the side closer to the connecting portion than the tip of the pressing piece.

It is preferable that the angle of the tip of the engaging claw and the angle of the corner of the tip of the pressing piece that comes into contact with the writing be a right angle or an acute angle.

It is preferable that an auxiliary engaging claw is formed on an inner surface of the second support piece on a side opposite to the engaging claw with a position corresponding to a tip of the pressing piece interposed therebetween.

[0008] Further, it is preferable that the holding piece is formed by folding back an extension formed from an end of the first support piece.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a clip according to the present invention. The clip 1 is formed by extruding a synthetic resin, and connects one end of the first support piece 2 and the second support piece 3 facing each other to the connecting portion 4.
And a pressing piece 6 bent in a V-shape from the other end of the first supporting piece is formed. It is preferable that the tip of the holding piece 6 be formed long enough to contact the inner surface of the second support piece 3.

A bulging portion 7 is formed on the inner surface of the front end of the holding piece 6, and a corner 7 a of the end of the holding piece 6 on the side of the second support piece 3 (a portion that contacts a surface of a document described later). Is set to be a right angle or an acute angle.

Although not shown, at the tip of the holding piece 6,
A knurl may be formed to increase friction with the paper surface.

Next, the second support piece 3 is formed to be longer than the first support piece 2, and the inner surface of the second support piece 3 is closer to the connecting portion 4 than the tip of the holding piece 6 to the document. Is formed with an engaging claw 8 which engages with the surface of. The engaging claw 8 has a triangular cross section, and its tip may be a right angle or an obtuse angle, but is preferably formed to be a right angle or an acute angle as shown in FIG.

When the clip having the above structure is used, the document 11 is inserted between the outer surface of the holding piece 6 and the inner surface of the second support piece 3 as shown in FIG.

When the document or the like 11 is to be pulled out from the clip 1 after insertion, the corner of the tip of the holding piece 6 comes into strong contact with the surface of the document 11 so that the holding piece 6 rises inside. In this case, the document 11 is pressed more strongly by the tip of the holding piece 6 and becomes a resistance to pulling out. Since the frictional resistance between the two is large, the pulling out resistance is extremely large, and the pulling out is performed unless a considerable force is applied. Therefore, the holding power of the document 11 is large.

When the document 11 is inserted, the leading end thereof is pressed downward by the pressing piece 6 and then engages with the engaging claw 8. Since the document 11 rides on the engaging claw 8, the height of the document 11 is raised higher than the actual height. Therefore, the pressing piece 6 is bent at a steeper angle with respect to the first support piece 2, and the pressing force due to its elasticity is increased.

Further, one surface (lower surface in the drawing) of the end portion of the document 11 is engaged with the engaging claw 8, and the other surface (upper surface in the drawing) is engaged with the tip of the holding piece 6. Then, the engaging claw 8 is also attached to the holding piece 6.
Of the document 11 are sharply engaged with the paper surface of the document 11 and bite into the paper surface, so that a large resistance force is obtained when the papers above and below the document 11 are removed.

As described above, since the engaging claw 8 is provided, the pressing force of the pressing piece 6 against the document 11 is increased, and both the upper and lower documents of the document 11 are hardly removed.
The document 11 is hard to slip out of the clip 1 as a whole,
The clip 1 can securely hold the document 11.

The higher the engaging claw 8 is, the stronger the pressing force of the pressing piece 6 is, but the more difficult it is for the document 11 to be inserted.

Next, FIG. 4 shows another example of the above-mentioned clip. The inner surface of the above-mentioned second support piece is opposed to the above-mentioned engaging claw 8 with a position corresponding to the tip of the holding piece interposed therebetween. An auxiliary engagement claw 9 is formed on the side. A second engaging claw 10 is also formed at an intermediate portion of the holding piece 6. The second engaging claw 10 may not be provided.

When using the clip 1 having the above structure,
As shown in FIG. 5, the outer surface of the holding piece 6 and the second support piece 3
The document 11 is inserted and sandwiched between the inner surface of the document 11. At this time, the document 11 rides on the auxiliary engagement claws 9 and the engagement claws 8 and is pressed downward by the holding pieces 6. Also in this case, since the height of the document 11 is higher than the actual height, the pressing piece 6 is further bent, and the pressing force due to elasticity is increased.

Further, one surface of the end portion of the document 11 is engaged with the engaging claw 8 and the auxiliary engaging claw 9 and the other surface is engaged with the tip of the holding piece 6, so that the document 11 is wavy. It becomes a state.
With the second engaging claw 10, the waving state becomes even more remarkable. In addition, the engagement claw 8, the holding piece 6, the auxiliary engagement claw 9, the second
Are engaged with the surface of the document 11 at an acute angle, and the biting force on the paper surface is further increased.

As described above, the frictional resistance due to the engagement of both sides of the document 11 is large, and
The resistance when extracting is large. Therefore, document 11
Is difficult to remove as a whole, and the clip can securely hold the document 11.

Also in this example, the higher the auxiliary engaging claw 9 is, the stronger the pressing force of the pressing piece 6 is. However, since it is difficult to insert the document 11, it is sufficient to consider the balance.

FIG. 6 shows another example of the clip. The clip 1 is also formed by extruding a synthetic resin so that the end of the first support piece 2 is extended through a thin hinge portion 5, and The extension portion 6 ′ is formed by folding the extension portion 6 ′ inward from the hinge portion 5 to form a holding piece 6 and abutting the tip of the holding piece 6 on the inner surface of the second support piece 3.

Since the holding piece 6 is bent inward from the thin hinge portion 5, the bent parts press against each other. Because of the action, the tip always strongly presses the inner surface of the second support piece 3. This is a different point from the clip shown in FIG.

According to the above configuration, as shown in FIG.
Is inserted, the front end of the holding piece 6 always strongly presses the inner surface of the second support piece 3, so that even if the number of documents 11 to be bound is small, it can be securely clamped.

Also in this example, the functions of the engaging claw, the auxiliary engaging claw 9 and the second engaging claw are the same as those described above, and the most important claw is the engaging claw 8. Next, the auxiliary engaging claw 9 and the second engaging claw 10 are next.

[0029]

According to the first aspect of the present invention, after inserting a document between the outer surface of the holding piece and the inner surface of the second support piece,
When a document or the like is to be extracted from the clip, the pressing piece is raised in the clip due to friction between the tip of the pressing piece and the document, and the resistance to pulling out is extremely large, so that the holding force of the document is large.

Further, when the document is inserted, the leading end thereof is pressed by the pressing piece and then rides on the engaging claw. Therefore, the height of the document is raised higher than the actual height, and the elasticity of the pressing piece increases. The pressing force increases.

As described above, the presence of the engaging claws increases the pressing force of the pressing piece against the document, so that the document as a whole hardly comes out of the clip, and although the structure is simple, the document can be securely clamped. .

According to the second aspect of the present invention, the engaging claw and the tip of the pressing piece engage with the document and act to bite when the document is pulled out. , It becomes harder to pull out.

According to the third aspect of the present invention, the document rides on the auxiliary engagement claw and the engagement claw, and is pressed downward by the pressing piece. Also in this case, since the height of the document is higher than the actual height, the pressing piece is more bent, and the pressing force due to its elasticity is increased.

Further, one surface of the end of the document is engaged with the engaging claw and the auxiliary engaging claw, and the other surface is engaged with the tip of the pressing piece, so that the document is in a wavy state.

As described above, the frictional resistance due to the engagement with both sides of the document is large, and the resistance when the corrugated document is extracted is also large. Therefore, the document is difficult to be pulled out as a whole, and the clip can securely hold the document.

According to the fourth aspect of the present invention, since the bent portions are pressed against each other, the pressing piece is subjected to elasticity to return to the original state with respect to the return, so that the tip is always strong in the second position. Of the supporting piece is pressed. Therefore, even if the number of documents to be stapled is small, the documents can be reliably held.
