In particular, by providing grooves on the inner wall of the top of the triangular shaft and providing protrusions corresponding to these on the outer wall of the knock member with a clip, it is possible to prevent radial rotation more reliably than the round shaft anti-rotation structure. In addition, the shaft cylinder is flat printed, and when the flat printed surface is placed on the flat surface as the front, the bottom surface and the clip one side are incorporated in parallel, and the new clip piece and shaft This is a positional relationship with printing, and has an excellent effect in appearance.

以下、本発明の最良の形態について、まず図１から図６の実施例１を参照して詳細に説明する。筆記具本体をなす軸筒１は、先軸１１と後軸１２とから構成されてなり、先軸１１は先端開口を有し、かつ前方に向かって次第に縮径する先具部が一体成形されてなり、軸筒１の横断面は略三角形状、いわゆる「おむすび」形状である。従って、この筆記具は机上に置いたときにも、転がり落ちないように形成されている。そして、後軸１２の横断面三角形の各頂点または角部に対応する位置には長手方向にそれぞれ係止溝１３が形成されている。   Hereinafter, the best mode of the present invention will be described in detail with reference to Example 1 of FIGS. A shaft cylinder 1 constituting a writing instrument main body is composed of a front shaft 11 and a rear shaft 12, and the front shaft 11 has a tip opening and is integrally formed with a tip portion that gradually decreases in diameter toward the front. Thus, the cross section of the shaft tube 1 has a substantially triangular shape, a so-called “rice ball” shape. Therefore, this writing instrument is formed so as not to roll down even when placed on a desk. A locking groove 13 is formed in the longitudinal direction at a position corresponding to each vertex or corner of the triangular cross section of the rear shaft 12.

軸筒１の内部軸方向には筆記体であるインキ収納用レフィール２が摺動可能に設けられている。このレフィール２の先端には先端チップ２１が固設されている。この先端チップ２１から少し後方に離間してスプリング後端を係止するための係止部２２が形成されている。そして、このスプリング係止部２２と軸筒１の先軸１１内にはリターンスプリング３が装着されて、レフィール２を常時後方に付勢している。また、レフィール２の後方にはレフィール２を軸筒１内において摺動・前進せしめるための作動機構が設けられている。この作動機構は、回転カム４と、この回転カム４に係合するノックカム５と、このノックカム５を作動せしめるノックキャップ６とから構成されている。   An ink storage refill 2 as a writing body is slidably provided in the inner axial direction of the shaft tube 1. A tip 21 is fixed to the tip of the refill 2. A locking portion 22 for locking the rear end of the spring is formed a little rearward from the tip 21. A return spring 3 is mounted in the spring engaging portion 22 and the front shaft 11 of the shaft tube 1 to constantly urge the refill 2 backward. Further, an operating mechanism for sliding and advancing the refill 2 in the shaft tube 1 is provided behind the refill 2. The operating mechanism includes a rotating cam 4, a knock cam 5 that engages with the rotating cam 4, and a knock cap 6 that operates the knock cam 5.

他方、ノック部材であるノックキャップ６の筒状本体６１には、上方から下方に向かって係止突条６２が形成されている。即ち、これらの係止突条６２は軸筒１の内壁に形成された係止溝１３に対応して１２０度間隔で形成されている。なお図中符号６３はノックキャップ６に一体的に設けられたクリップであり、符号６４はクリップ６３の先部裏側に形成された押圧突起であり、また符号１６は名入れ部分である。   On the other hand, a locking protrusion 62 is formed on the cylindrical main body 61 of the knock cap 6 that is a knock member from the upper side to the lower side. That is, these locking protrusions 62 are formed at intervals of 120 degrees corresponding to the locking grooves 13 formed on the inner wall of the shaft tube 1. In the figure, reference numeral 63 denotes a clip provided integrally with the knock cap 6, reference numeral 64 denotes a pressing protrusion formed on the back side of the front portion of the clip 63, and reference numeral 16 denotes a name entry portion.

次に、このような筆記具の組み付け手順について述べると、印刷が施された名入れ部分１６を有する後軸１２内に、スプリング３を取り付けたレフィール２および操作機構である回転カム４およびノックカム５を前方より落とし込む。次に、これら内部ユニットが組み付けられた後軸１２に先軸１１を圧入して組み付けて軸筒１とする。最後に、ノックキャップ６を軸筒１の後部の後軸１２に嵌合する。この場合、後軸１２の横断面三角形状の頂点に位置する部位にノックキャップ６のクリップ６１の裏側に一体的に形成された押圧突起６４を後軸１２の横断面三角形状の角部に対応する外壁に位置決めして、後方よりノックキャップ６の筒状本体６１の先部を後軸１２に挿入すると、ちょうど後軸１２の係止溝１３にノックキャップ６の係止リブ６２が位置決めされてワンタッチで組み立てられる利点がある。この場合、ノックキャップ６の内壁とノックカム５の外壁との抜け止め構造により、以後ノックキャップ６が筆記具から抜け落ちることがない。   Next, a procedure for assembling such a writing instrument will be described. A refill 2 having a spring 3 attached thereto, a rotary cam 4 and a knock cam 5 as operating mechanisms are installed in a rear shaft 12 having a name insertion portion 16 printed. Drop from the front. Next, the front shaft 11 is press-fitted into the rear shaft 12 to which these internal units are assembled, and assembled into the shaft cylinder 1. Finally, the knock cap 6 is fitted to the rear shaft 12 at the rear portion of the shaft tube 1. In this case, the pressing protrusion 64 integrally formed on the back side of the clip 61 of the knock cap 6 corresponds to the corner of the rear shaft 12 having a triangular shape in the cross section. When the front portion of the tubular body 61 of the knock cap 6 is inserted into the rear shaft 12 from the rear, the locking rib 62 of the knock cap 6 is positioned in the locking groove 13 of the rear shaft 12. There is an advantage of being assembled with one touch. In this case, the knock cap 6 will not fall out of the writing instrument thereafter due to the retaining structure between the inner wall of the knock cap 6 and the outer wall of the knock cam 5.

以下、本発明に係るクリップ付きノック部材の回り止め構造を用いた筆記具の動作について説明する。
まず、筆記の際には、後端ノック部材であるノックキャップ６をノックすると、ノックカム５が軸筒１の内壁に形成されたカム溝１５に案内されて前進する。このノックカム５の前進に伴ってこれと係合する回転カム４が回転されてレフィール２を前進せしめて、先軸１１の先端開口から先端チップ２１を突出せしめる。なお、筆記を終了した際にはノックキャップ６をノック操作することによって先端チップ２１を軸筒１内に収納することができる。 Hereinafter, the operation of the writing instrument using the anti-rotation structure for the knock member with a clip according to the present invention will be described.
First, at the time of writing, when the knock cap 6 which is a rear end knock member is knocked, the knock cam 5 is guided and advanced by the cam groove 15 formed on the inner wall of the shaft tube 1. As the knock cam 5 advances, the rotating cam 4 engaged with the knock cam 5 is rotated to advance the refill 2, and the tip 21 is protruded from the tip opening of the tip shaft 11. When the writing is completed, the tip 21 can be stored in the shaft cylinder 1 by knocking the knock cap 6.

なお、これらの操作中にノックキャップ６は軸筒１との間に係止溝１３と係止リブ６２とからなる回り止め手段が働いて軸筒１に関してノックキャップが回転してクリップ６３と軸筒１の側面に施された名入れ部分１６とのずれが生じることがない等の利点がある。   During these operations, the knock cap 6 rotates between the shaft cylinder 1 and the locking cap 13 and the locking rib 62 so that the knock cap rotates with respect to the shaft cylinder 1 to rotate the clip 63 and the shaft 63. There is an advantage that there is no deviation from the name putting portion 16 provided on the side surface of the tube 1.

机上に置いたときにも転がり落ちないように形成されている。即ち、三角軸ということで、外壁が平面構成であることから安定して置くことができる。この場合、ノックキャップ６はそのクリップ６３が真上に位置するように予め軸筒１の横断面三角形の頂部にクリップ６３が位置するように係止溝１３と係止リブ６２を設けておけば、さらに好適である。   It is formed so that it does not roll down when placed on a desk. That is, since it is a triangular axis, the outer wall can be placed stably because of its planar configuration. In this case, if the knock cap 6 is provided with the locking groove 13 and the locking rib 62 in advance so that the clip 63 is positioned at the top of the triangular cross section of the shaft cylinder 1 so that the clip 63 is positioned directly above. It is more preferable.

さらに、図７は本発明の実施例２による筆記具のクリップ付きノック部材の回り止め構造に関するものであって、後軸１２とノックキャップ６との関係を示す横断面図である。実施例１と逆に図示のように係止突起１５を軸筒１を構成する後軸１２の内壁に設け、これに対して係止溝６５をノックキャップ６の外壁に形成する。この実施例２によっても、実施例１と同様に軸筒１に関してノック部材の位置決めと回り止めという顕著な効果が得られる。   FIG. 7 is a cross-sectional view showing the relationship between the rear shaft 12 and the knock cap 6 relating to the structure for preventing rotation of the knock member with clip of the writing instrument according to the second embodiment of the present invention. In contrast to the first embodiment, as shown in the figure, a locking projection 15 is provided on the inner wall of the rear shaft 12 constituting the shaft cylinder 1, and a locking groove 65 is formed on the outer wall of the knock cap 6. According to the second embodiment, as in the first embodiment, a remarkable effect of positioning the knock member and preventing rotation with respect to the shaft tube 1 can be obtained.

なお、上記実施例における筆記具のクリップ付きノック部材の回り止め構造は、ボールペン等の他の筆記具であっても良い。   In addition, other writing implements, such as a ball-point pen, may be sufficient as the rotation prevention structure of the knock member with a clip of the writing implement in the said Example.
