　以下、本発明の実施形態について図面を参照しながら説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　図１中、符号１は、本発明に係る筆記具を示している。 In FIG. 1, reference numeral 1 indicates a writing instrument according to the present invention.
　この筆記具１は、インクＡ（図２に示す。）を収容した軸２と、この軸２を同軸で収容する筆記具本体３を備えている。 This writing instrument 1 includes a shaft 2 containing ink A (shown in FIG. 2) and a writing instrument main body 3 that coaxially accommodates this shaft 2.
　筆記具本体３は、先端部４側に先端支持部５が設けられ、後端部６側に後端支持部７が設けられている。 The writing instrument main body 3 is provided with a tip support portion 5 on the tip portion 4 side, and a rear end support portion 7 on the rear end portion 6 side.
　また、筆記具本体３の後端部６側には、軸２を先端部４側に向けて押える軸押え８が設けられている。 Further, a shaft presser 8 is provided on the rear end 6 side of the writing instrument main body 3 to press the shaft 2 toward the tip end 4 side.
　さらに、軸２は、一端側にペン先９を備え、このペン先９が先端部４側から突出している。 Further, the shaft 2 is provided with a pen tip 9 on one end side, and this pen tip 9 protrudes from the tip portion 4 side.
　さらに、筆記具本体３は、図２および図３にも示すように、たとえば円筒状の内筒１０およびたとえば円筒状の外筒１１を有している。 Further, as shown in FIGS. 2 and 3, the writing instrument main body 3 includes, for example, a cylindrical inner tube 10 and, for example, a cylindrical outer tube 11.
　内筒１０は、金属たとえばアルミニウム（硬質材料）で構成され、軸２を同軸で収容するようになっている。 The inner cylinder 10 is made of metal, such as aluminum (hard material), and is adapted to accommodate the shaft 2 coaxially.
　外筒１１は、アルミニウムより軟質であるシリコン（軟質材料）で構成され、内筒１０を同軸で収容するようになっている。 The outer cylinder 11 is made of silicon (soft material) that is softer than aluminum, and accommodates the inner cylinder 10 coaxially.
　先端支持部５は、図４～図７にも示すように、軸２の先端挿通孔１２と、この先端挿通孔１２に突出し軸２の先端部４側を支える軸支え部１３と、内筒１０の先端部４側に外嵌して内筒１０を固定する先端内筒固定部１４と、外筒１１の先端部４側に内嵌して外筒１１を固定する先端外筒固定部１５とを有している。 As shown in FIGS. 4 to 7, the tip support portion 5 includes a tip insertion hole 12 of the shaft 2, a shaft support portion 13 that protrudes into the tip insertion hole 12 and supports the tip portion 4 side of the shaft 2, and an inner cylinder. A tip inner cylinder fixing part 14 that fits onto the tip 4 side of the outer cylinder 10 to fix the inner cylinder 10, and a tip outer cylinder fixing part 15 that fits inside the tip 4 side of the outer cylinder 11 to fix the outer cylinder 11. It has
　後端支持部７は、図８～図１１にも示すように、軸２の後端挿通孔１６と、内筒１０の後端部６側に外嵌して内筒１０を固定する後端内筒固定部１７と、外筒１１の後端部６側に内嵌して外筒１１を固定する後端外筒固定部１８とを有している。 As shown in FIGS. 8 to 11, the rear end support part 7 has a rear end that fits into the rear end insertion hole 16 of the shaft 2 and the rear end 6 side of the inner cylinder 10 to fix the inner cylinder 10. It has an inner cylinder fixing part 17 and a rear end outer cylinder fixing part 18 that fits inside the rear end 6 side of the outer cylinder 11 to fix the outer cylinder 11.
　これにより、軸２と内筒１０との間には筒状の第１の間隙Ｓ１が形成され、内筒１０と外筒１１との間には筒状の第２の間隙Ｓ２が形成されるようになっている。 As a result, a first cylindrical gap S1 is formed between the shaft 2 and the inner tube 10, and a second cylindrical gap S2 is formed between the inner tube 10 and the outer tube 11. It looks like this.
　また、後端支持部７は、Ｌ字状の溝１９、すなわち、後端支持部７の後端から軸方向先端方向へ延びる第１溝２０と、この第１溝２０に連通し周方向に延びる第２溝２１と、この第２溝２１に連通し軸方向後端部６側に延びる第３溝２２とを有している。 In addition, the rear end support part 7 has an L-shaped groove 19, that is, a first groove 20 extending from the rear end of the rear end support part 7 in the axial direction, and a first groove 20 that communicates with the first groove 20 in the circumferential direction. It has an extending second groove 21 and a third groove 22 communicating with the second groove 21 and extending toward the rear end portion 6 in the axial direction.
　軸押え８は、図１３～図１５にも示すように、後端支持部７の後端挿通孔１６に着脱可能に内嵌する内嵌部２３と、この内嵌部２３に連接され、後端支持部７に当接するキャップ部２４と、内嵌部２３の周壁に突設され、後端支持部７の溝１９に係合する係合部２５とを有している。 As shown in FIGS. 13 to 15, the shaft presser 8 includes an inner fitting part 23 that is removably fitted into the rear end insertion hole 16 of the rear end support part 7, and is connected to this inner fitting part 23 and is connected to the rear end insertion hole 16 of the rear end support part 7. It has a cap part 24 that comes into contact with the end support part 7 , and an engaging part 25 that projects from the peripheral wall of the inner fitting part 23 and engages with the groove 19 of the rear end support part 7 .
　そして、軸２を内筒１０内に差し込んだ後、軸押え８の内嵌部２３を後端支持部７の後端挿通孔１６に係合部２５が第１溝２０に係合するように内嵌し、さらに軸押え８を係合部２５が第２溝２１に係合するように且つ第３溝２２の部位まで回動させることにより、軸２をペン先９が先端支持部５から突出する状態に押え付けることができるようになっている。 After inserting the shaft 2 into the inner cylinder 10, the inner fitting part 23 of the shaft presser 8 is inserted into the rear end insertion hole 16 of the rear end support part 7 so that the engaging part 25 engages with the first groove 20. By fitting the shaft 2 inward and rotating the shaft holder 8 so that the engaging portion 25 engages with the second groove 21 and up to the third groove 22, the pen tip 9 moves away from the tip support portion 5. It can be pressed into a protruding state.
　以上の構成によれば、内筒１０をアルミニウムで、外筒１１をシリコンで、それぞれ構成し、これら内筒１０および外筒１１の先端部４側を先端支持部５で固定するとともに、これら内筒１０および外筒１１の後端部６側を後端支持部７で固定し、これにより内筒１０と外筒１１との間には筒状の第２の間隙Ｓ２が形成されるようにしたので、図１６に示すように、筆記具本体３を手指Ｐで把持したとき、シリコンで構成された外筒１１は、内筒１０に拘束されることなく、径方向、軸方向、周方向に、比較的自由に弾性的に変形することができる。 According to the above configuration, the inner tube 10 is made of aluminum, and the outer tube 11 is made of silicon, and the distal end portions 4 sides of the inner tube 10 and the outer tube 11 are fixed with the tip support portion 5, and The rear end 6 sides of the cylinder 10 and the outer cylinder 11 are fixed by the rear end support part 7, so that a second cylindrical gap S2 is formed between the inner cylinder 10 and the outer cylinder 11. Therefore, as shown in FIG. 16, when the writing instrument main body 3 is gripped with the fingers P, the outer cylinder 11 made of silicone is not restrained by the inner cylinder 10 and moves in the radial direction, axial direction, and circumferential direction. , can be elastically deformed relatively freely.
　したがって、外筒１１の変形量を大きくすることができるので、字がうまく書けるようになる。 Therefore, since the amount of deformation of the outer cylinder 11 can be increased, characters can be written more effectively.
　この場合、外筒１１の内側にはアルミニウムで構成された内筒１０が存在するので、必要以上の変形が阻止される。 In this case, since the inner cylinder 10 made of aluminum exists inside the outer cylinder 11, more deformation than necessary is prevented.
　さらに、外筒１１は、両端が内筒１０の両端に固定された先端支持部５と後端支持部７とによって固定されているため、軸方向への延びを阻止することができる。 Furthermore, since both ends of the outer cylinder 11 are fixed by the front end support part 5 and the rear end support part 7, which are fixed to both ends of the inner cylinder 10, extension in the axial direction can be prevented.
　なお、上記実施形態では、内筒１０と外筒１１との間に筒状の第２の間隙Ｓ２が形成されるようにしたが、本発明はこれに限ることは無く、内筒１０の外周面と外筒１１の内周面とが接触しても内筒１０が外筒１１の変形を拘束しない構成であれば良い。 In the above embodiment, the cylindrical second gap S2 is formed between the inner cylinder 10 and the outer cylinder 11, but the present invention is not limited to this, and the outer circumference of the inner cylinder 10 Any configuration is acceptable as long as the inner cylinder 10 does not restrict the deformation of the outer cylinder 11 even if the surface contacts the inner peripheral surface of the outer cylinder 11.
　また、外筒１１は、シリコンで構成したが、これに限らず、筒状形状を維持できれば他の軟質材料でもよい。 Further, although the outer cylinder 11 is made of silicon, it is not limited to this, and may be made of other soft materials as long as it can maintain its cylindrical shape.
　さらに、内筒１０は、アルミニウムなどの金属で構成したが、これに限らず、硬質樹脂などでもよい。
　さらに、内筒１０および外筒１１は、円筒状に形成したが、これに限らず、たとえば角筒状でもよく、要するに筒状であればよい。 Furthermore, although the inner cylinder 10 is made of metal such as aluminum, it is not limited to this and may be made of hard resin or the like.
Furthermore, although the inner tube 10 and the outer tube 11 are formed in a cylindrical shape, they are not limited to this, and may be, for example, in a rectangular tube shape, and in short, any cylindrical shape may be used.
　以上に記載した本発明に関する開示は、少なくとも下記事項に要約することができる。 The disclosure regarding the present invention described above can be summarized at least as follows.
　すなわち、本発明に係る筆記具は、インクを収容した軸と、先端部と後端部とを有し、軸を収容する筆記具本体とを備え、筆記具本体は、軸を同軸で収容する、硬質材料で構成された内筒と、内筒を同軸で収容する、硬質材料より軟質の軟質材料で構成された外筒とを備えたことを特徴とするものである。 That is, the writing instrument according to the present invention includes a shaft containing ink, and a writing instrument body having a front end portion and a rear end portion and housing the shaft, and the writing instrument body is made of a hard material that coaxially accommodates the shaft.
