DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip used for holding and binding documents and the like.

[0002]

2. Description of the Related Art A conventional clip is, for example, a double clip which is used by expanding the contact surfaces by operating an operating rod with a finger, a doubly wound ring-shaped zem clip, or an elastic plate member. There is known a clip or the like that is bent by forming upper and lower abutting pieces and is used by using a predetermined pushing device (clip mounting device). (Hereinafter, referred to as the first related art group.) However, the double clip of the first related art group has no problem with respect to the clamping force, but when the size of the double clip is large, the pushing and expanding operation between the contact pieces is considerably increased. There is a problem in that the force is required and there is a case where expansion is impossible, and the operating rod is an obstacle, and the documents bundled by the clip become bulky when stacked. Further, in the paper clip of the same technology group, since the documents are only sandwiched between the rings, the clamping force is weak and a thick document cannot be bundled at all. Further, the clip that requires the use of the above-mentioned push-out device of the same technology group requires a separate clip push-out device, though it is a simple operation that requires no labor and has sufficient clamping force.

Therefore, the applicant of the present invention applies a pressing force to the expanded upper and lower contact surfaces with respect to the above-described clip of the first prior art group without using a separate mounting device as shown in FIG. He came up with the idea of a clip that can be occluded to obtain a clamping force. (See Japanese Utility Model Publication No. 6-71159)

The prior art described in this publication (hereinafter referred to as the "second prior art") continuously extends the upper and lower clamping pieces 3'from both ends of a bent portion 2'having a desired width. The elastic clip body 1'provided and the upper and lower clamping pieces 7'continuously extending from both ends of the bent portion 6'formed to have a desired width are provided, and the tips of the upper and lower clamping pieces are the above-mentioned. The width y'engaged with the upper and lower portions of the clip body 1'close to the bent portion 2'and the width y'formed between the tips is larger than the maximum width v'formed between the upper and lower clamping pieces 3'of the clip body 1 '. And an elastic pressing cover 5 ′ that is also narrow, and the pressing cover 5 ′ is slidably arranged outside the clip body 1 ′ so that the upper and lower clamping pieces 3 ′ of the clip body 1 ′ can be connected to each other. The present invention is configured so as to be brought close to each other in a pressing manner, and solves the problems of the first prior art group.

However, the second prior art is set because the pressing cover 5'is not pushed beyond the bending portion 3'b of the upper and lower holding pieces 3'of the clip body 1'even when the pressing cover 5'is pushed to the limit in the direction of the arrow. It was found that the gripping force against the document B ′ was not as strong as expected and that the document B ′ clamped by the upper and lower clamping pieces 3 ′ could be pulled out. (See FIG. 5 (c))
Even if the pressing cover 5'is pushed to the limit in the direction of the arrow, the bending portion 3'of the upper and lower clamping pieces 3'of the clip body 1'is
It has been discovered that, by not exceeding b, the clip body 1'is likely to spread against the pressing force of the pressing cover 5'and the pressing force of the pressing cover 5'may be attenuated early. (Refer to the same figure) Furthermore, when the document B ′ is sandwiched between the upper and lower clamping pieces 3 ′ of the clip body 1 ′, the bent portion 3′b of the clamping piece does not become flat, but remains bent in a chevron shape. I found the disadvantage of being bulky when stacking documents.
(See the figure)

The present invention has been made in view of the above-mentioned problems of the above-mentioned prior art, but in particular has been made by paying attention to the problem of the second prior art, and the purpose thereof is as follows. It is an object of the present invention to provide a clip that is not bulky and has excellent gripping force, in which a sandwiched document is not damaged, is hard to be removed, does not adversely affect a pressing cover, and has a strong sandwiching force.

[0007]

In order to achieve the above-mentioned object, the technical means made by the present invention is to extend upper and lower clamping pieces in a continuous and expanding manner from both ends of a bent portion having a desired width. An elastic clip body formed by bending the tip of the holding piece inward toward the bent portion and forming a pair of pressing claws facing each other, and both ends of the bent portion formed to a desired width The upper and lower clamping pieces are continuously extended from the clip body, the tips of the upper and lower clamping pieces are engaged with the upper and lower portions of the clip body near the bent portion, and the width formed between the tips of the clamping pieces is a clip. It is composed of an elastic pressing cover that is narrower than the maximum opening width formed between the upper and lower clamping pieces of the main body, and the pressing cover is slidably arranged outside the clip main body so that This is to bring the clamping pieces close to each other in a pressing manner. Also,
The lengths of the pair of pressing claws formed to face the tips of the upper and lower clamping pieces of the clip body may be different.

[0008]

By the above-mentioned technical means, the clip body is formed in a divergent shape in which the upper and lower clamping pieces are formed in an expanded shape from the bent portion,
Since a pair of pressing claws are bent inward toward the bent part and formed opposite to each other at the tip of the holding piece, it is possible to smoothly insert a bundle of documents etc. into the clip. Is. Then, if the pressing cover is then slid out of the clip body and pushed in, the insertion width formed between the upper and lower holding pieces of the cover is narrower than the maximum width formed between the upper and lower holding pieces of the clip body. Therefore, the upper and lower holding pieces of the cover slide forward and backward while pressing the upper and lower holding pieces of the clip body from the outside toward the inner side, and bring the upper and lower holding pieces of the clip body closer to each other. In addition to this, the pair of pressing claws are pressed by the pressing cover and the upper and lower clamping pieces of the clip body against the return elastic force (elastic force acting in the direction of the arrow in FIG. 4D), and a strong return elastic force is exerted. Demonstrate and strongly press the set documents.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the figure, C indicates the clip of the present invention, and the clip C
Is composed of the clip body 1 and the pressing cover 5, and is formed by bending a desired flat plate member such as a metal plate or a synthetic resin plate. The material of the clip C may be either an elastic material or an inelastic material as long as it is elastically configured.

The clip body 1 is bent from the center side of the desired flat plate member to form a bent portion 2 having a desired width x ₁ , and the upper and lower clamping pieces 3, 3 are continuously and expanded from both ends thereof. 3 is provided, and in the present embodiment, the tips of the holding pieces 3, 3 are bent inward toward the bending portion 2 to form a pair of pressing claws 4, 4 facing each other. The space formed between the pressing claws is defined as the insertion space z (FIG. 4 (a)).

Therefore, in this embodiment, the pressing claws 4, 4 are
The opening width y formed between the bent portions 3b and 3b forming the
Is the maximum width formed between the upper and lower holding pieces 3, 3 of the clip body 1, and the document B is easily inserted. Also,
The width x ₁ of the bent portion 2 can be appropriately set according to the thickness of documents to be bundled and is not limited in any way.

The pair of pressing claws 4 and 4 have a return elastic force (an elastic force acting in a direction of an arrow in FIG. 4D) when the pressing force cover 5 is slid and pushed outside the clip body 1. ) Against the upper and lower clamping pieces 7 of the pressing cover 5 and the clip body 1
The upper and lower clamping pieces 3 and 3 are pressed to exert a strong return elastic force to strongly press the set document B and clamp the document with a strong clamping force. The other purpose of forming the pressing claws is to bend the pair of pressing claws 4 and 4 against the resilient force when returning a large amount of documents B (document B thickened due to a large amount) as described above. No, this is to prevent the spread of the clip body 1. This clip body 1
With the effect of preventing the spread of the sheets, it is possible to prevent the bulkiness when the sandwiched documents B are stacked. Still another purpose of arranging the pressing claw is to prevent the document B from slipping out by causing a large resistance between the document B on the surface layer and the pressing claws 4 and 4 when the document B is held. By increasing this resistance, when the pressing force cover 5 is pulled back to release the sandwiched document B from the clip body 1, the document does not slip out, and the pressing cover 5 slides relatively smoothly,
That is, the upper and lower holding pieces 3, 3 of the clip body 1 are surely opened.

Further, the upper and lower clamping pieces 3, 3 of the clip body 1
By forming the pressing claws 4 and 4 facing each other as described above, when only the clip body 1 is put in and out of the pressing cover 5 without holding the document B, the tips of the upper and lower holding pieces 3 and 3 hold the fingertips. One of the purposes is to prevent the occurrence of such accidents.

The reason why one of the pair of pressing claws 4 and 4 is made long or short to have different lengths is as follows. That is, in general, if the pressing claws are formed to be short, the resilience becomes strong and the document B can be strongly clamped. However, if both the pressing claws 4 and 4 are shortened, as described above. As described above, the effect of preventing the spread of the clip main body 1 due to the flexure of the pressing claws 4 and 4 against the return elastic force is not sufficiently exerted, and conversely, both pressing claws 4 and 4 are lengthened. This is because a large amount of resistance is not sufficiently generated between the document B and the pressing claws 4 and 4, and the slip-through prevention effect of the document B is not sufficiently exerted.

Therefore, by forming one of the pair of pressing claws 4, 4 long or short, the pressing claws 4, 4 described above are formed.
The effect of preventing the spread of the clip body 1 due to the flexure against the return elastic force of the document B and the effect of preventing the slip-out of the document B due to the large resistance force generated between the document B and the pressing claws 4 and 4 are surely achieved. Try to show it.

On the other hand, the pressing cover 5 has upper and lower clamping pieces 7, 7 continuously extending from both ends of a bent portion 6 which is bent from the center of a desired flat plate member and has a desired width x _2. The insertion width y formed between the tips of the sandwiching pieces 7, 7 is narrower than the bent portion width x ₁ of the clip body 1 (FIG. 4 (a)). The insertion width y is narrower than the bent portion width x ₂ of the pressing cover 5. It should be noted that the above example is merely an example, and the insertion width y may be at least narrower than the maximum width v of the clip body 1, for example, the insertion width y may be wider than the insertion space z. However, it is optional.

By the way, the length of the upper and lower holding pieces 7, 7 is substantially the same as the length of the upper and lower holding pieces 3, 3 of the clip body 1, or the upper and lower holding pieces 7, 7 are formed a little longer. It is configured to cover the upper and lower clamping pieces 3 and 3 (see FIG. 1).

The above-mentioned required widths can be expressed as follows. [Insertion space z <Insertion width y <Bent portion width x ₁ <Width v] However, the above expression is an example, and at least the relationship of the insertion width y <the width v is sufficient, and the insertion width y <the difference. The relationship of the embedded space z is arbitrary.

Then, the upper and lower holding pieces 7, 7 of the pressing cover 5 are expanded to engage the upper and lower portions of the clip body 1 near the bent portion 2 with their tips to fit the upper and lower sides of the pressing cover 5. The tips of the strips 7, 7 are slidably arranged back and forth on the upper and lower sandwiching strips 3, 3 of the clip body 1 toward the bent portions 3b, 3b and are integrally set.

When the pressing cover 5 is completely pushed, a pair of pressing claws 4 and 4 formed opposite to the tips of the upper and lower holding pieces 3 and 3 of the clip body 1 are pressed against the return elastic force. .

As shown in FIGS. 2 and 3, the upper and lower clamping pieces 3, 3 of the clip body 1 are provided with guide groove portions 8, 8 extending from the vicinity of the bent portion 2 toward the bent portions 3b, 3b. , An inner curved guide piece 9, which engages with the guide groove portions 8,
9 is provided near the tips of the upper and lower clamping pieces 7, 7 of the pressing cover 5, whereby the guide pieces 9, 9 of the pressing cover 5 are in sliding contact with the guide groove portions 8, 8 of the clip body 1 and cannot be removed. In order to fit it in, the pressing cover 5 is slidably set on the clip body 1 with the inner curved guide piece 9 slidingly contacting the guide groove portion 8 (see FIG. 3).

In this embodiment, the guide pieces 9 and 9 of the pressing cover 5 are fitted into the guide groove portions 8 and 8 of the clip body 1 in a sliding contact manner and cannot be pulled out, and the upper and lower holding pieces 7 of the pressing cover 5 are inserted. Since the insertion width y formed between the clip body 1 and the clip body 7 is narrower than the bent portion width x1 of the clip body 1, the clip body 1 and the pressing cover 5 may be abruptly separated. Absent.

Although not shown, instead of the guide piece 9, one or a plurality of dowels (projections of a desired shape) may be provided on the inner surfaces of the tips of the upper and lower holding pieces 7, 7 of the pressing cover 5, respectively. In the present invention, the groove portion is not limited to the non-penetrating concave groove but also includes a through hole as shown in the drawing.

When the product is large, the clip body 1 is preferably made of a material that is thin to some extent in order to effectively exert the return elastic force and bending of the pair of pressing claws 4, 4. However, if this is done, the rigidity of the entire clip body 1 will be insufficient, so part of the side edges of the upper and lower clamping pieces 3, 3 of the clip body 1 will be bent in mutually opposite directions,
The bending pieces 10 and 10 are configured to improve rigidity. Further, when the bending pieces 10 and 10 are configured, when the both side edges of the clip body 1 are picked up and put in and out of the pressing cover 5, there is less concern that the upper and lower holding pieces 3 and 3 damage the fingertips, which is safer. , It's easier to get in and out.

Further, the pressing cover 5 is formed by drawing both side corners of the bent portion 6 to form a drawn portion 11, which suppresses the spread of the pressing cover itself to increase the pressing force against the clip body 1 and the document B The structure is such that a strong holding force can be exerted even when the amount is large (thick), and the strong pressing force is exerted without increasing the thickness of the material, so that it can be manufactured at low cost.

Next, an example of use will be described. First, since the clip main body 1 is formed in a divergent shape in which the upper and lower holding pieces 3 and 3 are formed in an expanded shape from the bent portion 2, the insertion space formed between the pressing claws 4 and 4 of the upper and lower holding pieces 3 and 3. Document B can be smoothly inserted into the clip from z (Fig. 4 (a)).
(B)).

Then, when the pressing cover 5 is slid and pushed forward (on the arrow w direction shown in FIG. 4C) on the upper and lower holding pieces 3, 3 of the clip body 1 on which the document B is set, The upper and lower clamping pieces 7, 7 of the cover 5 are on the upper and lower clamping pieces 3, 3 of the clip body 1 from outside to inside (opposing direction).
The upper and lower clamping pieces 3, 3 of the clip body 1 are brought closer to each other (the maximum opening width y is reduced) by pressing and sliding toward each other, so that the document B can be pressed from above and below and firmly clamped ( (See FIG. 4D)

Further, since the drawing shows the one made of an elastic material, the pair of pressing claws 4 and 4 are provided with the pressing cover 5.
The document B is firmly clamped by being elastically deformed by the pressing force of the upper and lower clamping pieces 7, 7. When the clip C of the present invention is removed, the pressing cover 5 may be pulled back to release the pressing state applied to the upper and lower holding pieces 3 of the clip body 1 contrary to the above operation.

The above-described embodiments are merely examples, and the present invention is not limited to these examples. For example, the expansion angle of the clip body 1, the clip body 1, and the pressing cover 5 are included.
The lengths, lateral widths, bent portion widths x ₁ , x _2, etc. of the respective upper and lower holding pieces 3, 3.7, 7 can be changed as appropriate, and the change can be freely made within the scope of the present invention. Also, the clip body 1
The pressing cover 5 and the pressing cover 5 may be made of the same material or different materials, and are arbitrary.

[0030]

According to the present invention, which has the above-described structure, the clip body, which is initially expanded, is gradually closed by the pressing force to obtain a clamping force. That is, since the clip main body is formed into a divergent shape in which upper and lower clamping pieces are formed in an expanded shape from the bent portion, and a pair of pressing claws facing toward the bent portion are formed to face each other, a bundle such as a document can be smoothly moved. If it can be inserted inside the clip, and then the slide cover is pushed in by sliding the outside of the clip main body in which the pressing cover is set on the above-mentioned documents, the insertion width formed between the upper and lower clamping pieces of the cover is at least the clip main body. Since the upper and lower clamping pieces of the cover are narrower than the maximum opening width between the upper and lower clamping pieces, the upper and lower clamping pieces of the cover slide while pressing on the upper and lower clamping pieces of the clip body from the outside to the inside to clamp the upper and lower sides of the clip body. Since the pieces are brought close to each other, a bundle such as a document can be pressed and held from above and below.

In addition to this, the pair of pressing claws are pressed against the return elastic force by the pressing cover and the upper and lower clamping pieces of the clip body, and exert a strong return elastic force to strongly press the set document. , Can be firmly clamped.
