Description

Clip

The present invention relates to a clip used for holding and binding a document or the like.

The conventional clip is, for example, a double clip used by extending the contact surface by operating the operation lever with a finger, a gem clip in a double-wound ring state, or an elastic plate-like body that is bent and joined up and down. ) And a clip used by using a predetermined extrusion device (clip mounting device) is known.

However, in the above double clip, there is no problem with respect to the clamping force, but when it becomes large, the operation which presses and widens between the abutting sides is quite necessary, and it may not be possible to expand it. When it became cumbersome and piled up documents by the clip, there was inconvenience that volume became large. In addition, in the case of the gem clip, the clamping force was weakened because only the documents were sandwiched between the rings, and the thick papers were not easily broken.

Moreover, in the clip which must use the said extrusion apparatus, although it does not require effort by simple operation, and has sufficient clamping force, the clip extrusion apparatus was needed separately.

Therefore, the present applicant expands a gem clip or a conventional clip in which the upper and lower abutment surfaces in a closed state are subjected to some external force, and uses a mounting device for a conventional clip that sandwiches documents from the upper and lower sides with the restoring force without using a separate mounting device. It was conceived to devise a clip which is closed by pressing pressure which is in contact with the upper and lower sides, and thus obtains a clamping force.

This invention is made | formed in view of such a problem which the prior art has, and the objective is to provide the clip which is excellent in clamping force by the clip attachment apparatus unnecessary and simple operation.

In order to achieve the above object, the clip of the present invention is a clip for continuously and remarkably extending the upper and lower clamping pieces from both ends of the bent portion having a desired width, and clamping the documents and the like using the elastic deformation between the upper and lower clamping pieces. A press cover made of an elastic material having a relatively large spring constant is mounted so as to be slidable on the outside of the clip body made of an elastic material having a relatively small spring constant. The clip main body has a pair of first upper and lower clamping pieces extending from both ends of the bent portion having a desired width and expandably, and the clamping portions of the tip ends of the upper and lower clamping pieces are bent inward and be molded toward the bent portion. The pressing cover has a pair of second upper and lower clamping pieces which are continuously spoken from both ends of the bent portion formed to a desired width, and the tip of the upper and lower clamping pieces are fitted between the upper and lower portions from the bent portion of the clip body and formed between the ends. It is shape | molded so that width may be narrower than the maximum width formed between the 1st upper and lower clamping pieces of a clip main body. When the 2nd upper and lower clamping piece of a press cover slides toward the front end side of the 1st upper and lower clamping piece of a clip main body, the clamping part of the 1st upper and lower clamping piece of a clip main body approaches each other.

It is preferable to provide a guide groove part in the 1st up-and-down clamping piece of a clip main body, and to provide the guide piece which conforms to a guide groove part in the front-end | tip of the 2nd up-down clamping piece of a press cover.

It is preferable to shape | mold one side of the bending part of the front-end | tip of the 1st upper and lower clamping piece of a clip main body by moving a predetermined distance forward.

It is preferable that ribs are provided at the upper and lower edges of the press cover bent portion, and ribs are provided at the upper and lower edges of the clip body first upper and lower clamping pieces.

[Action]

By the above technical means, since the front part of the clip main body which formed the upper and lower clamping pieces from the bend part is extended, the bundle of documents, etc. can be inserted smoothly inside a clip.

Then, if the press cover is slid out from the outside of the clip main body after that, the sandwiching width formed between the second upper and lower clamping pieces of the pressing cover is wider than the maximum width formed between the first upper and lower clamping pieces of the clip main body. In this narrow state, the second upper and lower clamping pieces of the press cover slide back and forth while pressing the first upper and lower clamping pieces of the clip main body from the outside toward the inner part, and the first upper and lower clamping pieces of the clip main body Close the upper and lower angular cross of each

At this time, since the clamping part of the front-end | tip clamping part of the 1st up-and-down clamping piece of a clip main body is bend | folded inward toward a bent part, elastic force generate | occur | produces also in this part. This elastic force is applied by the pressing force of the pressing cover to obtain a stronger clamping force. In addition, since the first upper and lower pincers are bent in the direction of interposing the documents, etc., a large resistance is generated between the surface layer and the bent portion of the documents against the direction in which the documents are pulled out. To act.

Since the tip of the bent portion of the first upper and lower clamping pieces of the clip body is bent inward toward the bent portion, the user's finger or the like is caught and no accident occurs.

When the clip is enlarged, the user may cut his or her finger at the upper and lower edges of the clip body or the upper and lower edges of the pressing cover. However, the user's fingers can be protected by installing ribs at the side edges of the former.

[Embodiment of the Invention]

With reference to FIGS. 1-7, the Example of the clip of this invention is demonstrated.

Example 1

1 is a cross-sectional view of the first embodiment of the clip A of the present invention, showing the operational relationship between the clip body 1 and the pressing cover 4. FIG. 2 is an exploded perspective view of the clip A of FIG. 1, FIG. 2 (a) shows the clip main body 1, and FIG. 2 (b) shows the press cover 4, respectively. 3 is a perspective view showing a state of use of the clip (A) of the present invention.

The clip A of the present invention, in the clip body 1 made of an elastic material having a relatively small spring constant, is made of elastic stainless steel (SUS 301) and a press cover 4 made of an elastic material having a relatively large spring constant. ), The metal type is carbon steel (S65C) for the machine structure or the resin type is polycarbonate. Here, the spring constant k is defined as F = kx when the displacement amount is x and the force is F.

The clip main body 1 and the press cover 4 are formed by bending desired flat plate bodies, such as a metal plate and a synthetic resin plate. The press cover 4 is attached to the outer side of the clip main body 1 so that a slide is possible, and the document etc. are clamped in the clip main body 1.

As shown in FIG. 2 (a), the clip main body 1 is bent from the center of the desired flat plate body to form a bent portion 2 having a desired width x, and continuous from both ends thereof. This is achieved by providing the first upper and lower clamping pieces 3 and 3 in an enlarged manner. In the present embodiment, the tip ends of the gripping pieces 3, 3 are bent inward toward the bent part 2 to form the gripping parts 3a, 3a, and the gripping parts 3a, 3a are formed. The space formed between the gaps is an insertion space z.

Therefore, in this embodiment, the width | variety v formed between the bending parts 3b and 3b which formed the clamping parts 3a and 3a has the 1st upper and lower clamping pieces 3 and 3 in the clip main body 1. As shown in FIG. ) Is the maximum width formed between them. As a result, in the above example, the clamping portion 3a is formed by bending. In this case, the insertion space z formed in the clamping parts 3a and 3a becomes the maximum width. In addition, the width | variety x of the bent part 2 is arbitrary, without being limited at all by making it correspond to the thickness of documents etc. which are attached.

On the other hand, the press cover 4 continuously speaks from both ends of the bent portion 5 which is bent from the center of the desired flat plate body and formed to the desired width x ', as shown in FIG. 2 (b). The interposed width y formed between the second upper and lower clamping pieces 6 and 6, and formed between the second clamping pieces 6 and 6, is larger than the bend width x of the clip body 1. It is formed in a narrow state. Moreover, the width | variety y which fits in is a state narrower than the width | variety x 'of the bending part of the press cover 4. FIG. The above example is only an example, and the width y to be fitted may be a state in which the width y is at least narrower than the maximum width v of the clip main body 1. For example, the insertion width y may be wider than the insertion space z, and may be arbitrary.

When each said width | variety is represented by a formula, it becomes as follows.

(Width to fit y 〈Bend width x 〈Insertion space z 〈Width v)

However, the above equation is an example, and may be at least a relationship of the insertion width y < width v, and is arbitrary, such as the relationship of the insertion width y <

Then, the second upper and lower clamping pieces 6 and 6 of the pressing cover 4 are expanded, and the tip is engaged with the upper and lower portions from the bent portion 2 of the clip main body 1, and the outer cover is pressed out. The tip of the second upper and lower clamping pieces 6 and 6 of 4) is placed on the first upper and lower clamping pieces 3 and 3 of the clip body 1 toward the lower part of the clamping parts 3a and 3a of the tip. It is disposed so as to be able to slide back and forth and is integrally set. Moreover, the clamping part 3a, 3a of the front-end | tip of the 1st upper and lower clamping pieces 3 and 3 of the clip main body 1 is made to mutually approach each other in the pressing state, when the press cover 4 is pushed in completely. In addition, the clamping portions 3a and 3a may be in contact with each other, as will be described later with reference to FIG.

As shown in FIG. 2 (a), the guide grooves 7 and 7 are provided on the upper surfaces of the first upper and lower clamping pieces 3 and 3 of the clip main body 1, and the guide grooves ( The inner curved guide pieces 8 and 8 matching with 7,7 are provided in the front-end | tip of the 2nd upper and lower clamping pieces 6 and 6 of the press cover 4. As shown in FIG. As a result, the press pieces 4 and 8 of the press cover 4 are in contact with the guide grooves 7 and 7 of the clip body 1 so as to be in contact with each other so as not to be pulled out. ) Is set on the clip main body 1 to be slidable by bringing the inner groove guide piece 8 into contact with the guide groove 7.

In this embodiment, the guide pieces 8 and 8 of the press cover 4 are in contact with the guide grooves 7 and 7 of the clip main body 1 and are fitted so as not to fall out, and the press cover. Since the clamping width y formed between the upper and lower clamping pieces 6 and 6 of (5) is formed in a narrower width than the bend width x of the clip main body 1, the clip main body ( There is no fear that 1) and the press cover 4 may be separated accidentally.

Although not shown, a plurality of dove tails (desired projections) may be provided on the inner surfaces of the tip ends of the second upper and lower clamping pieces 6 and 6 of the pressing cover 4 instead of the guide pieces 8. good. In the present embodiment, the groove portion is not limited to the penetrating state, but also includes a so-called recess portion that is in a non-penetrating state.

Next, an example of use of the clip of the present embodiment will be described with reference to FIG.

Since the first upper and lower clamping parts 3 and 3 are prevalent in the clip main body 1 from the bent part 2 toward the distal end in the expanded state, the tip of the first upper and lower clamping pieces 3 and 3 The document B can be smoothly inserted into the clip from the insertion space z formed between the sandwiching portions 3a and 3a (figure 1 (a) and (b)).

And then, the press cover 4 is slid to the front (arrow w direction shown in each angle) on the 1st upper and lower clamping pieces 3 and 3 of the clip main body 1 which set the said document B, When pushed in, the 2nd upper and lower clamping pieces 6 and 6 of the press cover 4 move inward from the outside on the 1st upper and lower clamping pieces 3 and 3 of the clip main body 1. Slide while pressing toward the top and close the first upper and lower clamping pieces 3 and 3 of the clip main body 1 (the insertion space z is reduced), so that the document B is moved up and down. It can be crimped firmly and can be firmly clamped (FIG. 1 (c) and FIG. 3).

Moreover, since the clip main body 1 and the press cover 4 are formed with the elastic material, the 1st upper and lower clamping pieces 3 and 3 are the 2nd upper and lower clamping pieces 6 and 6 of the press cover 4, respectively. It elastically deforms by the pressing force of) and firmly clamps the document (B). In addition, since not only the pressing force of the press cover 4 but also the elastic restoring force by the clamping parts 3a and 3a of the first clamping pieces 3 and 3 are generated, the clamping force of the document B is further strengthened. do. In addition, when the thickness of the document B becomes large, the sandwiching portions 3a and 3a of the first sandwiching pieces 3 and 3 are bent for the first time, and the spreading of the clip body 1 and the pressing cover 4 can be suppressed. Can be. This has the effect of making the whole bulky when stacking documents.

When removing the clip A, the press cover 4 is deflected backwards in reverse to the above operation, and the pressing state applied to the first upper and lower clamping pieces 3 and 3 of the clip main body 1 may be eliminated. (Fig. 1 (b)). When the pressing cover 4 is deflected to the rear, the first upper and lower clamping pieces of the clip main body 1 are bent in the insertion direction of the document or the like, so that a large resistance force is generated between the surface layer of the document and the bent portion. Thereby, the press cover 4 slides smoothly with respect to the clip main body 1, and can reliably open the 1st upper and lower clamping pieces 3 and 3 of the clip main body 1. As shown in FIG.

Example 2

4 is a longitudinal cross-sectional view of the second embodiment of the clip A of the present invention. FIG. 5: is a longitudinal cross-sectional view of the clip A shown in FIG. 4, and the maximum engagement state of the clip main body 1 and the press cover 4 is shown. 6 is an explanatory diagram showing a safety example when using the clip A of the present invention. In the second embodiment, as shown in FIG. 4, one side (upward in the figure) of the bent portions 3b and 3b at the tip of the first upper and lower clamping pieces 3 and 3 of the clip main body 1 (the upper side in the figure) In the left side, the mold is formed by a predetermined distance d. By forming in this way, as shown in FIG. 5, when the press cover 4 slides on the clip main body 1 as much as possible, and it engages as much as possible, the 1st upper and lower clamping piece 3 of the clip main body 1 The holding portions 3a and 3a of 3 are engaged with each other and are bent. In FIG. 5, the case where each clamping part 3a, 3a sets each free position without engaging with each other is shown by the dashed-dotted line.

If both clamping portions 3a and 3a are shortened, the elastic resistance of the clamping portion increases, and the binding force of the document can be strengthened, but the advantages obtained by the elastic deformation of the clamping portions 3a and 3a can be utilized. none. Therefore, as shown in the figure, the advantage of both can be utilized simultaneously by lengthening one clamping part 3a and shortening the other clamping part 3a.

The clamping portions 3a and 3a are bent inward toward the bent portion, whereby the leading edge of the document B can be easily fitted into the clip A. FIG.

Or as shown in FIG. 6 (a), even if a user inadvertently touches the finger | tip of the clip A, a finger does not bite into the clip A. FIG. On the other hand, FIG. 6 (b) shows the structure of the clip which is not considered. In this case, the bent part is not provided in the front-end | tip of the clip main body 1. As shown in FIG. In such a structure, a finger may bite into a clip tip.

Example 3

7 is a longitudinal sectional view of the third embodiment of the clip A of the present invention. In the present embodiment, as shown in FIG. 7, ribs 9 are provided at upper and lower edges of the bent portion 5 of the pressing cover 4, and the first upper and lower clamping pieces 3 of the clip body 1 are provided. The ribs 11 are provided in the upper and lower edges of, 3).

When the clip A becomes large, it is preferable to make the clip main body 1 from a thin material in order to utilize the elastic resistance of the clamping parts 3a and 3a. However, when the material is thin, the rigidity of the clip main body 1 is also insufficient, so that ribs 11 are provided on the first upper and lower clamping pieces 3 and 3 to supplement the strength of the clip main body 1, have. The rib 11 also serves to protect the user's finger from being injured during use.

In addition, with the enlargement of the clip A, an excessive external force is applied to the press cover 4, and the press cover 4 may cause plastic deformation. The rib 9 suppresses excessive expansion of the second upper and lower clamping pieces 6 and 6 and serves to reinforce the pressing cover 4. Moreover, a strong pressing force can be exhibited and it can manufacture at low cost, without increasing the thickness of a material.

Moreover, each said embodiment is only an example and is not limited to this at all, For example, each of the expansion angle of the clip main body 1, the clip main body 1, and the press cover 4 is made. The length, the horizontal width, the bend width (x, x '), etc. of the 1st and 2nd upper and lower clamping pieces 3,3.6,6 can be changed suitably. In addition, the clip main body 1 and the press cover 4 may be the same material, or a different material.

According to the present invention, it is a new clip which obtains clamping force by closing the upper and lower abutting surfaces of the clip body, which are initially expanded by pressing pressure, and expands the conventional gem clip or the upper and lower abutting surfaces of the closed state with some external force once. With respect to the clip (double clip, clip using the clip mounting apparatus, etc.) etc. which held the documents etc. from the top and bottom by the restoring force, the new useful clip which is excellent in the clamping force by the clip mounting apparatus is unnecessary, and simple operation is carried out. Is provided.

Since the clip body has a wide front in which the upper and lower narrow pieces are formed in the expanded state from the bent portion, a bundle of documents and the like can be smoothly inserted into the clip, and then the press cover is placed on the documents or the like. When the slide outside the main body slides in, the sandwiching width formed between the upper and lower clamping pieces of the pressing cover is in a state where the width of the pressing cover is narrower than the maximum width between the upper and lower clamping pieces of the clip main body. The upper and lower pinching pieces of the upper and lower pinching pieces are pushed toward the inward from the outside, and the upper and lower pinching pieces of the clip body are pressed against each other in order to bring the upper and lower pinching pieces closer together. Can cooperate.

The clip of the present invention can securely and securely file documents without using a special mounting device.
