Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper clip that can temporarily or one-touch memo paper or the like to be held or fastened. Further, the present invention particularly, as a gripping means, an elastic beard body such as rubber or bristles is projected from at least one side of the gripping body toward the other side,
The present invention relates to a type in which paper is held between the tip of the elastic beard and the other side facing the elastic beard by utilizing the elasticity of the elastic beard body.

[0002]

2. Description of the Related Art For example, Japanese Patent Publication No. 53-51212, which employs a one-sided flocking structure, is disclosed in Japanese Utility Model Publication No. 53-51212. Unexamined Japanese Patent Publication No. Sho 6
The disadvantages of the structure disclosed in Japanese Patent Application Laid-Open No. 0-129297 and those described in the above-mentioned two patents (that is, the point that the re-insertion becomes impossible due to being hindered by the beard of the rubber that has been inverted). In order to solve this problem, the elastic whiskers are projected obliquely from both sides facing each other so that the end faces of the whiskers are entirely (or partially)
Japanese Patent Publication No. 25296 discloses a configuration arranged in contact with
No. 17 discloses this.

[0003] The third configuration has a remarkably superior advantage as compared with the configurations disclosed in the two previous publications.

That is, Japanese Utility Model Publication No. 53-51212 and Japanese Unexamined Patent Publication No.
In the configuration disclosed in Japanese Patent Application Publication No. 0-129297, when the paper is pulled out parallel to the direction of introduction of the memo paper, the beard remains inverted with respect to the opposing wall surface, and is used by restoring the beard once with thick paper. Or the paper must be pulled out in the horizontal direction so that the beard does not reverse. And the third patent publication 25296
The structure disclosed in Japanese Patent Application Publication No. 17 has an improved structure which seems to almost eliminate the above-mentioned disadvantages.

[0005]

However, the structure described in Japanese Patent Publication No. 2529617 is not always perfect in terms of the problem of reversing the beard. Have been found to be entangled with each other, and the entangled beards hinder the re-introduction of paper, and it has been confirmed by experiments by the present inventor that problems such as difficulty in inserting the paper as it is are still left.
In addition, since it is necessary to prepare a pair of whiskers on the upper and lower sides, the height (thickness) of the entire product increases, and it has not been possible to satisfy the current thin-oriented design. In addition, it is inconvenient in terms of cost to use one pair (that is, two) of whiskers although they are the same parts.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a one-touch-type paper nip which is further improved by eliminating the above-mentioned various disadvantages of the prior art.

[0007]

According to the present invention, one side of a first substrate and a second substrate facing each other are engaged to form a substantially U-shape, and the first substrate is swingable. A beard plate member in which a plurality of rubber beards are obliquely implanted at predetermined intervals and arrangements is provided, and a recess is formed in the second substrate at a position facing the beard plate member of the first substrate. The recess is provided with a non-swingable projection at a position that does not interfere with the swinging of the rubber beard.

[0008]

According to the present invention, a rubber whisker plate is used only on one side (that is, one of the first substrate and the second substrate), and no transition of the whiskers is made between the tip of the whiskers and the facing surface. A minimum space is provided so as not to disturb, and a projection is provided on the facing side at a position that does not hinder the movement of the beard, and the paper is sandwiched and held between the projection and the tip of the beard. The rubber whiskers can be freely changed (displaced) without any influence of the opposing surface side when removing and inserting the paper. Even when pulling out the paper, the whiskers can be easily restored and continuous use is extremely easy It can be done reliably. In addition, the above-mentioned protrusion cannot be displaced.

Further, only one beard plate needs to be used, and the beard can be sufficiently restored by forming only a small space on the facing side.
It is less susceptible to design constraints and is more cost effective.

Further, since the projection provided on the side facing the whiskers can be formed integrally with the substrate, the cost can be reduced as a whole, but the shape is simple even if it is formed as a separate component in advance and attached later. Therefore, it can be formed inexpensively as compared with the conventional technique using two whiskers.

[0011] Regarding the paper holding, the present invention is a mechanism in which the paper is sandwiched and held between the front end face of the rubber whiskers and the projection located at a slightly distant place. Therefore, when thin paper is sandwiched, it seems that the holding force is weak at first glance because the paper bends to the space side, but the paper pulling strength (gripping force) is actually
As a result, it was confirmed that a resistance value of several hundred grams was stably obtained, and there was no problem in practical use, and that a sufficient gripping force was obtained.

The reason is that the gap between the rubber whiskers and the protrusions needs to be separated by only a few millimeters (strictly, to a position avoiding the imaginary bending line of the whiskers). It may be slight, and it is considered that the paper bends as described above because the paper is extremely fine and sufficient holding force is obtained. Of course, when inserting the paper, the end face of the rubber whiskers is free, so that the paper can be easily inserted.

[0013]

FIG. 1 is a perspective view of a paper clip according to a preferred embodiment of the present invention, and FIG. 2 is an exploded perspective view thereof.
Although FIGS. 3 to 5 are slightly different in detail from the configurations of FIGS. 1 and 2, the description schematically shows the positional relationship between the rubber whiskers 17 and the projections 22 and the degree of projection, which are major features of the present invention. FIG. 3 is a front view, FIG. 4 is a cross-sectional view in the horizontal direction, and FIG. 5 is a cross-sectional view in the vertical direction.

1 to 5, the paper clip according to the present invention indicated by reference numeral 10 has a substantially U-shaped appearance as a whole, and is provided with an opening 18 for inserting paper and an opposite side of the opening. And a connecting base 19. This paper clip 10
Comprises a first substrate 11 and a second substrate 12 having a desired shape such as a rectangular shape, a circular shape, or a semi-circular shape having one side joined to each other in a cantilever shape, and the first substrate 11 A plurality of rubber whiskers 17 projecting obliquely on the side of the second substrate 12 are provided at a predetermined interval.
The beard plate 13 has an elongated beardless portion 16 at the center in this embodiment. In addition, this beard plate portion 13
And an engagement portion 14 for engaging the second substrate 12 adjacent to the second substrate 12. The engaging portion 14 in the illustrated example has locking claws 15 provided on both side walls, so that a convenient assembly can be achieved by a snap fastening connection with the connecting portion of the second substrate 12 as described later. It has become.

On the other hand, the second substrate 12 formed opposite to the first substrate 11 has a recess 20 at a position opposite to the beard plate portion 13 of the first substrate 11. At a position facing the engaging portion 14 of the first substrate 11, a locking projection piece 21 elastically coupled to the locking claw 15 by snap fastening,
21 are formed facing each other as shown. Recess 20
Has a depth such that the rubber whiskers 17 can swing freely in a state where the first substrate 11 and the second substrate 12 are opposed to each other, engaged and assembled.

Further, an elongated protrusion 22 is formed in the recess 20 at a position facing the beardless portion 16. The protrusion 22 is a locking auxiliary protrusion for locking the paper, and has a triangular cross section in the illustrated example. When the paper is sandwiched, it is more preferable that the trace of the corner of the triangle at the sandwiched portion does not stick to the paper. Locking auxiliary projection 22
The protrusion height of the first substrate 11 may be set to be flush with the protruding tip of the rubber whiskers 17 of the first substrate 11 or may be formed to be slightly higher than the protruding tip of the rubber whiskers 17 so as to be relatively high Good. Further, the rubber whiskers 17 may be formed relatively low so as to be slightly distant from the protruding tip thereof. However, if the whiskers are too low, there is a risk that the initial purpose of holding and holding the paper is reduced. Therefore, it is desirable to set the height to be at least flush with the protruding tip of the rubber whiskers 17 or to be slightly protruded from the protruding tip of the rubber whiskers 17.

At the bottom of the second substrate 12, for example, FIG.
As shown in FIG. 2, a plate-shaped permanent magnet 30 is attached, and a detachable attachment by magnetism is possible. Of course, as the attachment means, a magnet, an adhesive tape or other known means can be adopted.

Various conditions can be adopted for the relationship between the length of the rubber whiskers 17 and the height of the locking auxiliary projections 22.

That is, in the configuration shown in FIGS.
7 shows a state in which all of the distal end portion of the locking auxiliary protrusion 22 is bitten below the distal end of the locking auxiliary projection 22. As shown in the figure, in this embodiment, the locking assisting projections 22 act as projections having a locking assisting function on the side walls 24 formed by the recesses 20 of the second substrate 12 in addition to the projections 22 located at the center. I have. 6 and 7 simulating the rocking motion of the rubber beard 17 in this configuration, the tip of the beard at the normal position and the second substrate 12 are shown.
Is formed so that the tip of the beard does not come into contact with it when swinging and hinder swinging and returning, so that it does not hit the virtual imaginary line F of the beard. .

FIGS. 8 and 9 show another embodiment of the relationship between the rubber whiskers 17 and the projections 22. FIG. This embodiment shows an example in which only a part of the tip of the rubber whiskers 17 bites below the tip of the locking auxiliary projection 22. This configuration can be achieved by gradually inclining the surface of the locking auxiliary projection 22 toward the opening 18 as shown in FIG. In this embodiment, the rubber whiskers 17 close to the opening 18 side of the paper insertion port are used.
A slight gap is formed between the tip and the surface of the locking auxiliary projection 22, but the rubber whiskers 17
It is in a state of being cut below the tip of No. 2.

FIGS. 10 to 12 show still another embodiment. In this embodiment, as shown in FIG. 12, the locking auxiliary projections 22 are only the projections 22 formed at the center of the recesses 20 of the second substrate 12, and both sides of the second substrate 12 shown in FIG. Is not formed in this embodiment. In addition, the entire distal end portion of all the rubber whiskers 17 is configured to bite below the distal end of the protrusion 22.

FIGS. 13 to 15 show still another embodiment. That is, the protrusion 2 is located at the center of the recess 20 of the second substrate 12.
Unlike the previous embodiment in which the second substrate 12 is formed, only the side wall 24 of the recess 20 of the second substrate 12 has the function of the locking auxiliary projection in this embodiment. Accordingly, the arrangement of the rubber whiskers 17 formed on the first substrate 11 is also arranged at intervals on both sides to form beardless portions 16, 16, and the center beardless portion 16 formed in the previous embodiment is replaced by both. They are arranged aside.

FIGS. 16 to 18 show still another embodiment of the present invention, in which the main body is horizontally long as shown. In FIG. 17, the length of the rubber whiskers has a structure in which all of the distal ends are cut below the distal ends of the locking auxiliary projections 22. In FIG. 18, the length of the locking auxiliary projections 22 varies. The center projection 22a has a rubber beard 17 at its tip.
The protrusions 22b, 22b on both sides thereof are formed to be slightly shorter than the tip of the rubber whiskers 17 so as to bite from the tip of the rubber beard 17, and the second substrate 11 The height of the side walls 24, 24 formed on both sides is the same as the height of the center projection 22a.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this embodiment. For example, the rubber whiskers 17 formed on the first substrate 11 may be transparent to the second substrate 12, and the recesses 20 and the projections 22 formed on the second substrate 12 may be transparent to the first substrate 11. .

[0025]

According to the present invention, since the paper sandwiching by the combination of the rubber whiskers and the projections is constituted as described above, when the paper or the like is pulled out, the upper and lower whiskers are partially entangled with each other as in the conventional example. Thus, the conventional disadvantage that the entangled whiskers become a hindrance even when paper is introduced again could be completely overcome.

That is, in the present invention, a rubber whisker plate is used only on one side, and a minimum necessary space is provided between the front end portion and the facing portion of the whisker so as not to hinder any displacement of the whisker.
On the opposite side, a projection is provided at a position that does not hinder the movement of the beard, and the paper is sandwiched and held between the projection and the tip of the beard. Change (transition) freely without being affected by
When the paper is pulled out, the rubber whiskers can be easily restored, and the continuous use can be made extremely easily and reliably.

Further, the rubber beard plate to be used may be provided on only one side, and the rubber beard can be sufficiently restored by forming a small space on the facing side, so that the rubber beard plate can be made thin and can be used in a thin design. Restrictions are reduced, which is advantageous in terms of cost.

Further, since the projections provided on the side facing the rubber whiskers can be formed integrally with the substrate, the cost can be reduced as a whole, but the shape is simple even if they are formed as separate parts in advance and then retrofitted. Therefore, it can be formed at a lower cost as compared with the prior art using two whiskers.
