Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a clip for a writing instrument that is suitable when a writing instrument such as a fountain pen is attached to, for example, a clothing pocket or a notebook.
Here, the writing instrument includes not only a writing instrument such as a ballpoint pen, a mechanical pencil, and a fountain pen, but also a tool provided with a writing instrument type container such as an applicator for applying a colored liquid to an article and a cosmetic tool.
[0002]
[Prior art]
In general, a writing instrument such as a fountain pen is known that includes a writing instrument body having a pen core and a cap that can be attached to and detached from the writing instrument body. In addition, a clip for holding and holding an object to be attached (object to be clamped) is provided in order for the user to carry such a writing instrument by attaching it to a pocket such as clothes or the cover of a notebook.
[0003]
Conventionally, various kinds of writing instrument clips have been adopted, for example, one disclosed in Japanese Utility Model Registration No. 2561056.
The clip for writing instruments shown in this publication is provided with two large and small pressing projections on the back surface (inner surface) of the clip body for pressing the object to be clamped on the surface of the cap (main body).
To attach a writing instrument having a clip configured in this manner to a clothing pocket (clamped object), first, the clip body is elastically deformed so that the tip of the clip is separated from the surface of the cap body, and then the clothing pocket This is done by inserting the edge of the clothes pocket between the pressing projection and the cap body while the writing instrument body is housed inside.
[0004]
At this time, when the object to be clamped is thin, the object to be clamped is held between the large pressing protrusion and the cap body. On the other hand, when the object to be clamped is thick, the object to be clamped is held between the large and small pressing protrusions and the cap body.
[0005]
[Problems to be solved by the invention]
By the way, in order to reliably and stably attach the writing instrument to the object to be clamped, in the conventional clip, the clip force (pressure contact force of the object to be attached by the pressing protrusion) is set large. For this reason, in the conventional clip for writing instruments, the clip force concentrates on a part of the object to be sandwiched through the pressing protrusion, and thus the object to be sandwiched may be damaged.
[0006]
In order to solve such a problem, for example, it is conceivable to cover the pressing protrusion with a cushioning material to suppress damage to the object to be clamped. In this case, however, the number of parts increases and the work at the time of clip assembly becomes complicated. A new problem arises.
Further, in recent years, there has been a demand for a small dimensional ratio of the clip body in the width direction to the shaft diameter of the cap body from the design surface of the writing instrument clip. Thus, when the width direction dimension of the clip body is reduced, there is a problem that the writing instrument cannot be reliably and stably attached to the object to be held.
[0007]
The present invention has been made to solve the above technical problem, and has a configuration in which the width direction dimension of the clip pressing piece formed by folding the clip body is set to a dimension larger than the width direction dimension of the clip body. An object of the present invention is to provide a clip for a writing instrument that suppresses damage to an object to be clamped.
Moreover, even if it is a clip with a small dimensional ratio of the width direction dimension of the clip main body to the shaft diameter of the cap main body, it is possible to provide a writing instrument clip that can securely and stably attach the writing instrument to the object to be clamped. Objective.
[0008]
[Means for Solving the Problems]
A clip for a writing instrument made to achieve the above object is a clip for an elastically deformable writing instrument that holds and clamps an object to be clamped with the writing instrument exterior body, the clip body provided on the writing instrument exterior body, A clip pressing piece formed by folding back an end portion of the clip body, and the dimension of the clip pressing piece in the width direction is set to be larger than the dimension of the clip body in the width direction.
[0009]
Since it is comprised in this way, clip force acts on a to-be-clamped object via a wide clip press piece. Therefore, the clip force is distributed and transmitted to the object to be clamped, and damage to the object to be clamped can be suppressed.
Further, since the clip pressing piece can prevent the object to be clamped from being damaged, it is not necessary to cover the pressing protrusion with a buffer material as in the conventional case. As a result, the number of parts can be reduced and the clip assembling work can be simplified.
[0010]
Furthermore, since the dimension in the width direction of the clip pressing piece is set to be larger than the dimension in the width direction of the clip body, the width direction dimension of the clip body can be appropriately determined according to the shaft diameter of the writing instrument. A writing instrument with a high stability can be obtained. Further, even if the clip has a small dimensional ratio of the width dimension of the clip body to the shaft diameter of the cap body, the writing instrument can be reliably and stably attached to the object to be clamped.
[0011]
In addition, since the width direction dimension of the clip body can be appropriately determined (smaller) according to the shaft diameter of the writing instrument, even if the axial length of the writing instrument is short, the finger does not contact the clip body during use, Good usability can be obtained.
[0012]
Here, it is desirable that the clip pressing piece is formed of a pressing piece having a curvature that warps the back side of the clip body.
In this way, since the clip pressing piece is configured, the gap between the clip pressing piece and the writing instrument exterior body gradually decreases from the clip main body end portion (folded portion) toward the clip pressing piece intermediate portion. When the writing instrument is attached to the clip, the clip pressing piece functions as a clip guide piece, and the object to be attached can be smoothly inserted.
[0013]
Further, the planar shape of the clip pressing piece has a curved outline that gradually increases the width direction dimension from the end of the clip body toward the clip pressing piece intermediate part, and the clip pressing piece from the clip pressing piece intermediate part has a curved outline. It is desirable that the shape has a curved outline that gradually decreases the widthwise dimension toward the tip.
Since it is comprised in this way, the clip press piece with the wide intermediate part of a clip press piece can be obtained.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.

The rear view which shows the principal part of the clip for writing instruments, FIG. 3 (a) and (b) is the front view and side view (right side) which show the writing instrument (ball-point pen) in which the clip for writing instruments which concerns on 1st embodiment of this invention was used. Is a plan view).
In FIG. 1 to FIG. 3, a clip for a writing instrument denoted by reference numeral 1 includes a clip body 2 and a clip pressing piece 3, and is attached to an end of the writing instrument body (writing tool exterior body) 4 on the side opposite to the pen core. The clip body 2 and the clip pressing piece 3 are formed by folding back the end of the clip body 2. Reference symbol A denotes a capless writing instrument.
[0015]
The clip body 2 includes a clip base piece 5 and a clip attachment piece 6 and is formed of a thin metal piece that can be elastically deformed as a whole.
As shown in FIG. 1A, the clip base piece 5 has a substantially trapezoidal shape with a width direction dimension that narrows from the clip attachment piece side end toward the non-clip attachment side end (clip pressing piece 3 side). Is formed. Further, as shown in FIG. 1B, the clip base piece 5 is formed in a mountain shape having a gentle curve with the vicinity of the clip mounting piece as a vertex.
[0016]
The clip attachment piece 6 is formed by bending the clip base piece 5 and has an end face 6 a that fits the end face 4 a of the writing instrument body 4. In addition, a positioning convex portion 4 a for the writing instrument main body 4 protrudes from the end surface 6 a of the clip mounting piece 6.
[0017]
The clip pressing piece 3 is composed of a pressing piece having a pressing portion 3a capable of pressing the object to be clamped on the surface of the writing instrument main body 4, and is folded back to the end of the clip main body 2 on the side opposite to the clip mounting piece (end of the clip main body). Is provided.
The width direction dimension of the clip pressing piece 3 is set to be larger than the width direction dimension of the clip body 2. Thereby, the clip force of the writing instrument A acts on the object to be clamped via the wide (wide contact area) clip pressing piece 3.
[0018]
Moreover, as shown in FIG. 1A, the clip pressing piece 3 has a curved outline that gradually increases the width direction dimension from the end b of the clip body 2 toward the clip pressing piece intermediate part a. And it is formed in the shape which has the outline of the curve which makes a width direction dimension small gradually toward the front-end | tip part c of a clip press piece from the clip press piece intermediate part a. In addition, the clip pressing piece 3 is formed in a curved surface having a substantially chevron-shaped side surface with a curvature that warps the back side of the clip body 2 as shown in FIG.
[0019]
Thereby, the planar shape of the clip pressing piece 3 becomes a so-called streamline type, and a clip for a writing instrument having a wide clip pressing piece intermediate portion a in a shape is obtained.
Further, when the side surface shape of the clip pressing piece 3 is substantially chevron, the gap between the clip pressing piece 3 and the writing instrument body 4 is clip-pressed from the clip body end b (folded portion) as shown in FIG. Since the size gradually decreases toward the middle portion a, the clip pressing piece 3 functions as a clip guide piece when the writing instrument A is attached to the attachment, and the attachment portion can be smoothly inserted.
[0020]
In order to attach the writing instrument including the clip configured as described above to an object to be clamped such as a clothing pocket, the conventional method is performed.
That is, first, the clip body 2 is elastically deformed so that the clip tip portion (clip pressing piece 3) is separated from the surface of the writing instrument body 4, and then the pressing portion 3a and the writing instrument body are stored while the writing instrument body 4 is housed in the clothes pocket. 4 Insert the edge of the clothes pocket between.
[0021]
At this time, the pressing part 3a of the clip pressing piece 3 comes into contact with the object to be clamped such as a clothing pocket, and the clip force acts on the object to be clamped via the wide pressing part 3a.
Therefore, even if the clip force by the clip 1 and the writing instrument body 4 (pressing force by the clip pressing piece 3) is set large, the clip force is distributed and transmitted to the object to be clamped.
[0022]
Therefore, the clip force is distributed and transmitted to the object to be clamped, and damage to the object to be clamped can be suppressed.
Further, since the clip force is distributed and transmitted to the object to be clamped, a conventionally required cushioning material becomes unnecessary, and the number of parts can be reduced.
[0023]
Furthermore, since the width direction dimension of the clip pressing piece is set to be larger than the width direction dimension of the clip body, the width direction dimension of the clip body can be appropriately determined according to the shaft diameter of the writing instrument. A writing instrument with a high stability can be obtained. In addition, even if the clip has a small dimension ratio of the width dimension of the clip body to the shaft diameter of the cap body, a wide clip pressing piece is provided, so the writing instrument can be securely and stably attached to the object to be clamped can do.
[0024]
In addition, since the width direction dimension of the clip body can be appropriately determined (smaller) according to the shaft diameter of the writing instrument, even if the axial length of the writing instrument is short, the finger does not contact the clip body during use, Good usability can be obtained.
[0025]
In the present embodiment, the color applied to the clip is not described, but the clip body 2 and the clip pressing piece 3 may be the same color, or may be different from each other. .
In this case, when a color different from the surface color of the clip body is applied to the non-pressing surface d of the clip pressing piece, the clip pressing piece having a color different from the surface color of the clip body is visually recognized, and the writing tool is good in color. A clip can be obtained.
[0026]
Moreover, in this embodiment, although the case where the writing instrument main body 2 and the clip 1 separate from the writing instrument main body 2 were attached was demonstrated, it is not limited to this in particular, It is provided integrally with the writing instrument main body 2. Also good.
In addition, in this embodiment, although the case where it applied to the capless writing instrument A was demonstrated, it is not limited to this in particular, It can apply also to the writing instrument with a cap.
[0027]
