【従来の技術】[Prior art]

従来、筆記具のキャップにおいて、筆記具本体を装着する筒状部と、筆記具を ポケットなどに収容する際にポケットの布などを挾み込むためのクリップ部を合 成樹脂の射出成形品として一体に形成してなるものが知られている。 Conventionally, in a writing instrument cap, a tubular part for mounting the writing instrument main body and a clip part for inserting the cloth etc. in the pocket when the writing instrument is stored in the pocket are integrally formed as an injection molded product of synthetic resin. What is done is known.

【0003】 このクリップ部及び/または筒状部の互いに対向する位置に突起を形成してな るものは、更にクリップ部の挟持性や係留め性を向上させたものとして知られて いる。It is known that the clip portion and / or the tubular portion are provided with protrusions at positions facing each other, and the clip portion is further improved in gripping and locking properties.

【0004】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

上述のような従来の筆記具のキャップは、合成樹脂の一体成形品であるが故に 次のような問題があった。クリップ部または筒状部の一方に形成した突起と、こ の突起に相当する位置の他方との間には金型の構造上若干の隙間が必要であり、 この隙間を設けなくてはならないためにクリップ部の係留め力や挟持力をあまり 強くできないという問題である。 The cap of the conventional writing instrument as described above has the following problems because it is an integrally molded product of synthetic resin. Due to the structure of the mold, a slight gap is required between the protrusion formed on one of the clip part or the tubular part and the other at the position corresponding to this protrusion, and this gap must be provided. In addition, the problem is that the locking and clamping force of the clip part cannot be increased very much.

【0005】 また、樹脂の収縮することを利用して、成形後、クリップ部が内側に撓むよう に設計し、クリップ部の突起が成形後に筒状部の外壁に当接するようなすことも 考えられるが、このようなものは設計時に各部の寸法や、形状など、多くの要因 を考慮しなくてはならず、実際上なかなか目的のものが得られないという問題が あった。この問題は、特に、ABS樹脂やAS樹脂などの比較的収縮の少ない材 料を使用した場合顕著であった。It is also conceivable that the shrinkage of the resin is used to design the clip portion to bend inward after molding so that the projection of the clip portion contacts the outer wall of the tubular portion after molding. However, there was a problem in that such a product had to take into consideration many factors such as the size and shape of each part at the time of design, and it was difficult to obtain the desired product in practice. This problem was particularly noticeable when a material such as ABS resin or AS resin having a relatively small shrinkage was used.

【実施例】【Example】

以下、図面に基づき本考案の実施例について説明する。 図1に示すものは、本考案の筆記具のキャップAであり、合成樹脂の一体成形 品として形成されている。キャップAは筆記具本体(図示せず)を装着する筒状 部1とその筒状部1の底部分側を基部3として筆記具挿入孔2側に延在するクリ ップ部4とからなっている。クリップ部4の先端部分には係留め突起501が形 成され、この係留め突起501と間隔6を存して基部3側に係留め突起502が 形成されている。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a cap A of the writing instrument of the present invention, which is formed as an integrally molded product of synthetic resin. The cap A is composed of a tubular portion 1 on which a writing instrument main body (not shown) is mounted, and a clip portion 4 extending toward the writing instrument insertion hole 2 side with the bottom portion side of the tubular portion 1 as a base portion 3. . An engaging protrusion 501 is formed on the tip portion of the clip portion 4, and an engaging protrusion 502 is formed on the base portion 3 side with a space 6 from the engaging protrusion 501.

【0008】 筒状部1の外壁であって、前記間隔6に相当する位置にも係留め突起503が 形成されている。クリップ部の突起と筒状部の突起と、それぞれ1個ずつのみの 突起によりクリップ部に布などを挾持するものでは、布の形状は各突起の頂点で ある2点のみを支点としてクランク状に曲げられるのみであり、おのずとその挾 持力も弱いが、本考案のものは、少なくとも3点を支点とし、布などを強制的に 曲げるものであるので、たとえ突起の頂部とそれに対向する部材との間に隙間が あったとしても強い挾持力が得られるものである。A locking projection 503 is also formed on the outer wall of the tubular portion 1 at a position corresponding to the interval 6. In the case of holding a cloth or the like on the clip part with only one protrusion on the clip part and one protrusion on the tubular part, the shape of the cloth is cranked with only the two vertices of each protrusion as fulcrums. Although it can only be bent and its holding power is naturally weak, the present invention uses at least three fulcrums as a fulcrum to forcibly bend cloth and the like, so even if the top of the protrusion and the member facing it are Even if there is a gap between them, a strong holding force can be obtained.

【0009】 ここで、係留め突起501は、突起先端に対して筒状部開口端側の稜部分とク リップ部4の基部3側の稜部分とが略対象形となるような形状となっている。ま た、これに対して、他の係留め突起502、503は、その突起先端512、5 13に対して筒状部開口端側の稜部分522、523が緩やかな稜線となってい る。これによって、係留め突起が増えたことによるポケットなどの挾みにくさを 極力解消するものである。また、クリップ部4は、筒状部1とクリップ部4との 間の距離が基部3側及び筒状部開口端側で狭く、クリップ部4の中程になるにつ れて広くなるように形成されている。これにより、布等を筒状部1とクリップ部 4との間に挾んだ際に、前記係留め突起502、503の筒状部開口端側の稜部 分522、523が積極的に当接する。よって、係留め突起において、面積が多 い部分にて布等と接触するので、挿入し易さ及び抜け難さを確保しつつ、布を挾 んだ状態での位置ずれのし難さを付加したものである。更に、係留め突起502 と係留め突起503との位置関係において、係留め突起503の先端513が係 留め突起502の稜部分522に対向するようなしてあるので、布に面接触的に 接触する部分と、その布の裏面にて点接触的に接触する部分とによって挟持する のでさらにその挟持力及び係留める力において信頼性の増すものである。Here, the engaging protrusion 501 has a shape such that the ridge portion on the opening end side of the tubular portion and the ridge portion on the base 3 side of the clip portion 4 are substantially symmetrical with respect to the tip of the protrusion. ing. On the other hand, in the other engaging protrusions 502 and 503, the ridge portions 522 and 523 on the opening end side of the tubular portion are gentle ridge lines with respect to the protrusion tips 512 and 513. By doing so, it is possible to eliminate the difficulty of gripping pockets and the like due to the increased number of locking projections. Further, in the clip portion 4, the distance between the tubular portion 1 and the clip portion 4 is narrow on the base portion 3 side and the tubular portion opening end side, and becomes wider toward the middle of the clip portion 4. Has been formed. As a result, when cloth or the like is sandwiched between the tubular portion 1 and the clip portion 4, the ridge portions 522, 523 of the engaging projections 502, 503 on the open end side of the tubular portion are positively applied. Contact. Therefore, since the large area of the locking protrusion contacts the cloth, etc., it is easy to insert it and it is difficult to pull it out, and it is also difficult to shift the position when the cloth is sandwiched. It was done. Further, in the positional relationship between the locking projection 502 and the locking projection 503, the tip 513 of the locking projection 503 is arranged to face the ridge portion 522 of the locking projection 502, so that it comes into surface-contact with the cloth. Since it is sandwiched by the part and the part which comes into point-contact with the back surface of the cloth, the reliability of the clamping force and the locking force is further increased.

【0010】 図2、図3に他の実施例について示す。図1のものと同様にクリップ部4に2 個と筒状部に1個の係留め突起を形成したものであるが、それぞれの位置関係を 工夫したものである。つまり、クリップ部4に形成する2個の係留め突起504 、505をクリップ部4の長手方向に対して垂直の方向に並べ、その間に筒状部 に形成した係留め突起506が位置するようなしたものである。本例のものでは 、図1に示すものより若干長手方向の力に対して弱いものであるが、その代りに クリップ部にて挾持したものが、横方向(長手方向に対する垂直の方向)にずれ ることを抑制し、挿入口の広いポケットなどに収容したような場合でも筆記具が 斜めになって正常な挾持力を発揮し難くなることを抑制するものである。2 and 3 show another embodiment. As in the case of FIG. 1, two locking projections are formed on the clip portion 4 and one locking projection is formed on the tubular portion, but the positional relationship of each is devised. That is, the two locking protrusions 504 and 505 formed on the clip portion 4 are arranged in a direction perpendicular to the longitudinal direction of the clip portion 4, and the locking protrusion 506 formed on the tubular portion is located between them. It was done. This example is slightly weaker than the one shown in FIG. 1 against the force in the longitudinal direction, but instead, the one held by the clip part is displaced laterally (direction perpendicular to the longitudinal direction). This prevents the writing instrument from tilting and becoming difficult to exert a normal gripping force even when it is accommodated in a pocket with a wide insertion opening or the like.

【0011】 本考案の筆記具のペン先取り付け構造は、以上の他にも本考案の要旨を逸脱し ない限りで種々なせるものである。 一例を挙げると、上記のものは全て係留め突起が合計3個のものについて説明 したが、クリップ部に形成された係留め突起と筒状部に形成された係留め突起と の位置関係が互い違いになっていれば良く、その数の合計が3個以上であれば良 い。また、クリップ部または筒状部の一方に形成される、2個の係留め突起間に 位置する他方の突起は1個である必要はなく、複数並んだものであっても良い。 更に、上記の例では、どれもクリップ部4に複数の係留め突起が形成されるもの について説明したが、筒状部1に2個形成し、クリップ部4に1個形成したもの であっても良い。The pen tip mounting structure of the writing instrument of the present invention can be variously modified in addition to the above, without departing from the gist of the present invention. As an example, all of the above have been described with a total of three locking projections, but the positional relationship between the locking projections formed on the clip part and the locking projections formed on the tubular part is different. If the total number is 3 or more, it is good. Further, the other protrusion located between the two locking protrusions formed on one of the clip portion or the tubular portion does not have to be one, and a plurality of protrusions may be arranged. Further, in each of the above examples, the clip portion 4 has a plurality of engaging projections formed thereon, but two pieces are formed on the tubular portion 1 and one piece is formed on the clip portion 4. Is also good.
