Description

【０００１】
【発明の属する技術分野】
本発明は、紐部材を着脱自在に装着してなる紐部材付き筆記具に関する。
【０００２】
【従来の技術】
従来から、ボールペン等の筆記具に紐部材を装着しているものは知られている。そうした筆記具においては、紐部材を首から掛けている状態で、紐部材が何かに引っ掛かって首を締め付けられない様に、ある程度の力が加わると取付部から紐部材が外れるように紐部材の結び方や取付構造に工夫をしている。例えば、特開平７−３２３６９６号公報のように、筆記具の軸筒の側面に二箇所で係合部を有した取付部が設けられ、掛け紐の両端に固定した固定具を着脱可能となるように係止した筆記具が開示されている。
【０００３】
【発明が解決しようとする課題】
しかし、前記した従来技術においては、取付部に構造的に弾性を与えているので、取付部の構造が複雑であるとともに、大きくなるので、筆記時に手がぶつかったり、握りにくいという不具合が発生していた。また、ある程度の力で取付部と固定具が確実に外れるには、寸法精度を厳密にとる必要がある。また、紐部材を取付部に固着しなければならないので、組立作業が複雑になるという問題があった。
【０００４】
本発明は上記問題を鑑み、構造が簡単で、筆記具に紐部材を容易に装着することができる、組立作業が容易な紐部材付き筆記具を提供するものである。
【０００５】
【課題を解決するための手段】
前記目的を達成するために本発明では、筆記具に紐部材を着脱自在に装着してなる紐部材付き筆記具において、筆記具用部品の側面に凸部を形成するとともに、紐部材の両端に、Ｃ型状の取付部を一体に形成し、該取付部を凸部に着脱自在に係合する。
【０００６】
また、前記筆記具用部品に貫通孔を形成するとともに、該貫通孔に棒状物を貫挿し、該棒状物によって前記凸部を形成する。
【０００７】
本発明の筆記具用部品とは、軸筒、キャップ、クリップ、尾栓等、一般的に知られている筆記具を構成する部品のことである。
【０００８】
【発明の実施の形態】
本発明の紐部材には、ポリプロピレン、ポリエチレン等の軟質樹脂材料や、シリコーンゴム、ブチルゴム、スチレン系エラストマー、オレフィン系エラストマー等のゴムまたはエラストマー等の弾性変形可能な材料を適宜選択して使用することができる。
【０００９】
取付部をＣ型状にすることにより、凸部の突出量を小さく設定することができるので、筆記時に手がぶつかったり、握りにくいという不具合の発生を抑えることができる。
【００１０】
また、筆記具用部品に、貫通孔を形成し、該貫通孔に棒状物を筆記具用部品より突出した状態に保持し、凸部とすることにより、凸部を有する専用の筆記具用部品を必要とせず、筆記具用部品に貫通孔を形成するだけなので、従来から使用している筆記具用部品を用いることができる。
【００１１】
【実施例】
本発明の実施例を、図面を用いて説明する。
図１から４に示す第１の実施例の紐部材付き筆記具１は、軸筒２、インキ収容管３、チップ部材（図示せず）、口金４とノック体５、回転カム６、カム溝（図示せず）のノック機構を有するノック式筆記具であり、軸筒２の先端にはグリップ部材７を配設し、軸筒の後端部２ａの側面に２個所の凸部８を形成する。
【００１２】
ポリプロピレンからなる紐部材９の両端には、Ｃリング状からなる取付部１０を一体に形成し、該取付部１０を前記した凸部８に着脱自在に装着して本発明の紐部材付き筆記具１を作製した。この時、凸部８の端面に取付部１０の内径より大きい膨出部８ａ形成する。そうすることにより、取付部１０を凸部８に装着した際に、凸部８から取付部１０が抜け落ちすることがなくなる。
【００１３】
取付部１０を凸部８に装着する際には、取付部１０の切り欠き部１０ａを凸部８に当接させ押し込むことにより、切り欠き部１０ａは、弾性変形により拡がる（図２の矢印Ｆ方向）ので簡単に装着できる。また、拡がった切り欠き部１０ａは、装着後、元に戻る（図４の矢印Ｇ方向）。
【００１４】
反対に、紐部材９に力が加わると取付部１０にも力が加わり、切り欠き部１０ａは、弾性変形により拡がるので、ある程度の力（切り欠き部１０ａの間隙が凸部の径より大きくなる力）になると凸部８から取付部１０が外れる。
【００１５】
図５、図６に示す第２の実施例の紐部材付き筆記具１１は、軸筒１２、、インキ収容管（図示せず）、チップ部材１３、口金１４、尾栓１５からなる一般的に知られているボールペンであり、尾栓１５の後端部１５ａ側に、尾栓１５を貫通するように貫通孔１９を形成する。
【００１６】
前記貫通孔１９の一方の貫通孔１９ａに第一の固定部材１８ａを貫挿し、他方の貫通孔１９ｂ側より第二の固定部材１８ｂを第一の固定部材１８ａに螺着して凸部１８を形成する。このとき、凸部１８が軸筒１２の側面に２個所で突出するように設定しておく。
【００１７】
紐部材１７の両端には、Ｃ型状に形成した取付部１７ａを、ブチルゴムで一体に成形してある。紐部材１７を実施例１と同様な方法で、凸部１８に着脱自在に装着して紐部材付き筆記具１１を作製した。
【００１８】
図７に示す第３の実施例の紐部材付き筆記具２１は、軸筒２２と一体に形成したクリップ２３の取付部２４に、クリップの取付部２４を貫通するように貫通孔２５を形成し、実施例２と同様の棒状物（図示せず）を嵌挿してなるものである。
【００１９】
尚、本実施例では、便宜上、軸筒、尾栓、クリップの取付部に凸部を形成しているが、キャップ、ノック体等、一般的に知られている筆記具を構成する筆記具用部品に凸部あるいは貫通孔を形成してもよい。
【００２０】
【発明の効果】
本発明は前述した構成なので、凸部とＣ型状という構造が極めて簡単でかつ、筆記具に紐部材を容易に装着することができる。また、紐部材と取付部を一体に形成しているので、紐部材を取付部に固着する作業が簡略されので、紐部材を筆記具に取り付ける作業も容易である、紐部材付き筆記具を提供することができた。

The present invention relates to a writing instrument with a string member formed by detachably attaching a string member.
[0002]
[Prior art]
Conventionally, it has been known that a string member is attached to a writing instrument such as a ballpoint pen. In such a writing instrument, when the string member is hung from the neck, the string member can be detached from the attachment portion when a certain amount of force is applied so that the neck member is caught by something and the neck cannot be tightened. The way of tying and the mounting structure are devised. For example, as disclosed in Japanese Patent Application Laid-Open No. 7-323696, attachment portions having engagement portions are provided at two positions on the side surface of the shaft of the writing instrument so that the fixing tool fixed to both ends of the hanging strap can be attached and detached. A writing instrument that is locked to the is disclosed.
