【考案の詳細な説明】
この考案は芯保護用のキャップを外簡に装着するだけで
、自動的に筆記必要量の芯を突出保持できる筆記具の改
良に関する。[Detailed Description of the Invention] This invention relates to an improvement in a writing instrument that can automatically protrude and hold the necessary amount of lead for writing by simply attaching a lead protection cap to the outer case.
従来のノック式筆記具では、不使用時には芯が外筒内に
収納されているために、筆記具においてはまずノック動
作を行い芯の突出量を確認してから筆記を行うという動
作を必ず必要とした。In conventional knock-type writing instruments, the lead is stored inside the outer cylinder when not in use, so it is always necessary to first perform a knocking motion, check the amount of protrusion of the lead, and then write. .
この考案は上記ノック動作を不用とし、芯保護用のキャ
ップを筆記終続時に装着するだけで、次の筆記時には筆
記必要量の芯を突出保持できる筆記具を提供することを
目的とする。The object of this invention is to provide a writing instrument which eliminates the need for the above-mentioned knocking action and can protrude and hold the necessary amount of lead for next writing by simply attaching the cap for protecting the lead at the end of writing.
以下にこの考案の一実施例について図面を参照して説明
する。An embodiment of this invention will be described below with reference to the drawings.
この考案は外筒1の先端には着脱自在に嵌合された芯保
護用のキャップ2と、該外筒1内に摺動可能に収納され
た芯送り出し部3とを有する。This invention has a cap 2 for protecting the lead which is removably fitted to the tip of the outer cylinder 1, and a lead feeding part 3 which is slidably housed within the outer cylinder 1.
上記外筒1は第1図、第2図示のように筒状に形或され
、その先端側は開口し、他方、後端側は突出環状壁4に
着脱可能に嵌合した芯パイプ係止用の後端キャップ5に
よって封止されている。The outer cylinder 1 has a cylindrical shape as shown in FIGS. 1 and 2, and its front end side is open, while its rear end side has a core pipe locking part that is removably fitted into the protruding annular wall 4. It is sealed with a rear end cap 5.
上記後端キャップ5と上記突出環状壁4との嵌合は、例
えば、突出環状壁4の内周に切溝4aを刻設し、この切
溝4aと係合する突起5aを後端キャップ5の外周に突
設して、後述する芯パイプへの換芯補充時等に回転して
着脱自在に形或されている。The fitting between the rear end cap 5 and the protruding annular wall 4 can be achieved by, for example, cutting a cut groove 4a on the inner periphery of the protruding annular wall 4, and inserting a protrusion 5a that engages with the cut groove 4a into the rear end cap 5. It is formed so as to protrude from the outer periphery of the core pipe so that it can be rotated and detached when re-coring or refilling the core pipe, which will be described later.
尚、上記後端キャップ5は、着脱自在に形威され、かつ
嵌金時に後述する芯パイプの後退方向の移動を規制でき
れば如何なる構威でもよい。Note that the rear end cap 5 may have any structure as long as it is removably shaped and can restrict the movement of the core pipe in the backward direction, which will be described later, when the cap is fitted.
また、上記外筒1の内壁先端近傍には、キャップ係止用
の長孔6が所定の長さに穿設され、さらに、該外筒1の
内部にはこの外筒1の内壁係止部7に固定され、先端が
内方に折曲した固定筒8を介して、上記芯送り出し部3
が軸方向に摺動可能に収納されている。Further, near the tip of the inner wall of the outer cylinder 1, a long hole 6 for locking the cap is bored to a predetermined length, and an inner wall locking portion of the outer cylinder 1 is provided inside the outer cylinder 1. The core feeding section 3
is housed so that it can slide in the axial direction.
上記芯送り出し部3は、先端近傍にキャップ保合用段部
9aおよび固定筒係合用段部9bを有する内筒9と、こ
の内筒9の先端に嵌合された先具10と、該内筒9の内
部に摺動可能に収納された芯パイプ11とを有する。The lead feeding section 3 includes an inner cylinder 9 having a cap retaining step 9a and a fixed cylinder engaging step 9b near the tip, a tip 10 fitted to the tip of the inner cylinder 9, and a tip 10 fitted to the tip of the inner cylinder 9. A core pipe 11 is slidably housed inside the core pipe 9.
上記芯パイプ11は、内筒9から突出させた後端を上記
後端キャップ5に当接または後端キャップ5と少しの隙
間が設けられ後端方向への移動を規制されていると共に
、他方、その先端には芯送り出し機構12が装着されて
いる。The core pipe 11 has its rear end protruding from the inner cylinder 9 in contact with the rear end cap 5 or has a small gap between the core pipe 11 and the rear end cap 5 to restrict its movement in the rear end direction. , a core feeding mechanism 12 is attached to the tip thereof.
上記芯送り出し機構12は、第1図、第2図示のように
、芯パイプ11に嵌合したリードチャックと、このリー
ドチャック13の頭部に外嵌したチャツク締め付け管1
4の後端に当接し、チャック締め付け管14の後退方向
の移動を規制するスリーブ15と、このスリーブ15と
芯パイプ11との間に弾着された弾性体16とを備えて
いる。As shown in FIGS. 1 and 2, the lead feeding mechanism 12 includes a lead chuck fitted onto the lead pipe 11, and a chuck tightening tube 1 fitted onto the head of the lead chuck 13.
A sleeve 15 that contacts the rear end of the chuck clamping tube 4 and restricts movement of the chuck fastening tube 14 in the backward direction, and an elastic body 16 that is elastically attached between the sleeve 15 and the core pipe 11.
上記芯保護用のキャップ2は、外筒1とほぼ同径の筒状
をなすキャップ本体17と、このキャップ本体17に内
嵌した嵌合筒18とを有し、該嵌合筒18の外周にはキ
ャップ装着時に上記外筒1の長”JL6と係合する突起
19が、また、嵌合筒18の内部には芯送り出し部3の
先端部を収納するキャップ{L20が設けられている。The cap 2 for protecting the core has a cylindrical cap body 17 having approximately the same diameter as the outer tube 1, and a fitting tube 18 fitted inside the cap body 17, and the outer circumference of the fitting tube 18. A protrusion 19 that engages with the length "JL6" of the outer tube 1 when the cap is attached is provided inside the fitting tube 18, and a cap {L20 for accommodating the tip of the lead feeding section 3 is provided inside the fitting tube 18.
次にこの考案の動作について説明する。Next, the operation of this invention will be explained.
第2図に示すように筆記終了時にキャップ2を外筒1に
嵌合させると、キャップ2の嵌合筒18の先端は外筒1
のキャップ保合川段部9aと係合すると共に、嵌合筒1
8の突起19は外筒1の長孔6に係止される。As shown in FIG. 2, when the cap 2 is fitted into the outer cylinder 1 at the end of writing, the tip of the fitting cylinder 18 of the cap 2 is inserted into the outer cylinder 1.
The cap is engaged with the stepped portion 9a of the fitting tube 1.
The protrusion 19 of 8 is locked into the elongated hole 6 of the outer cylinder 1.
そこで、キャップ2の先端を外筒1の開口先端まで押圧
すれば、芯パイプ11は後端キャップ5によって、後退
方向の移動が阻止されているために、内筒9全体が後退
することとなる。Therefore, if the tip of the cap 2 is pressed to the open tip of the outer tube 1, the entire inner tube 9 will move backward because the core pipe 11 is prevented from moving in the backward direction by the rear end cap 5. .
従って、この動作はちょうどノック動作されたことと同
じ結果となり、キャップ2は芯送り出し機構12の弾性
体16の弾発力によって、第2図示の位置に自動的に移
動する。Therefore, this operation has the same result as a knocking operation, and the cap 2 is automatically moved to the position shown in the second figure by the elastic force of the elastic body 16 of the lead feeding mechanism 12.
即ち、第2図示の寸法A一寸法B(ノック分)寸法Cの
筆記量分だけ常に芯21が先具10から突出された状態
となる。That is, the lead 21 is always protruded from the tip 10 by the writing amount of dimension A - dimension B (knocking amount) and dimension C shown in the second diagram.
従って、第1図示のように、次の筆記時にキャップ2を
外筒1から外すだけで、芯21は常に筆記状態となって
いる。Therefore, as shown in the first diagram, the lead 21 is always in a writing state by simply removing the cap 2 from the outer cylinder 1 at the next writing time.
以上記載のようにこの考案の筆記具によれば、筆記終了
時に芯保護用のキャップを閉じるだけで、芯は筆記量分
だけ突出保持されるので、次の筆記時にキャップを外せ
ば即座に筆記が可能となる等極めて優れた実用的効果が
ある。As described above, according to the writing instrument of this invention, just by closing the cap to protect the lead when you finish writing, the lead is held protruding by the amount of writing, so you can immediately write by removing the cap the next time you write. This has extremely excellent practical effects, such as making it possible.
尚、この実施例ではシャープペンシルについて説明した
が、これに限定されることなくノック式の筆記具であれ
ば如何なるものでもよい。In this embodiment, a mechanical pencil has been described, but the present invention is not limited to this, and any knock-type writing instrument may be used.
