Description

図1(A)及び(B)並びに図2に加えて図4及び図5も参照すると、リフィール3後方のリフィール室2c内には例えば合成樹脂製のノック部材5が配置されており、リフィール3は圧縮バネ4によりノック部材5に向けて付勢されている。軸筒2の後端側開口2bには中空で例えば合成樹脂製の尾栓6が螺合されており、尾栓6の中空空間内にはノック部材5が長手軸線K−K方向に移動可能に保持されている。この場合、ノック部材5の前端のほぼ中央に形成された凸部5がリフィール3の後端のほぼ中央に形成された凹部3c内に受容されており、それによってリフィール3とノック部材5とが互いに整列される。本発明による実施例では、ノック部材5はリフィール室2cのほぼ中央に位置するよう尾栓6により保持されており、したがってリフィール3もリフィール室2cのほぼ中央に位置するよう整列されている。なお、リフィール3に凸部を形成しノック部材5に凹部を設けるようにしてもよい。更に、ノック部材5には凸部5の後方にフランジ5が形成されており、凸部5が凹部3c内に受容されるとノック部材5とリフィール3の後端との間に環状溝3dが形成される。 Referring to FIGS. 4 and 5 in addition to FIGS. 1 (A) and 1 (B) and FIG. 2, for example, a knock member 5 made of a synthetic resin is disposed in the refill chamber 2 c behind the refill 3. Is urged toward the knock member 5 by the compression spring 4. A hollow tail plug 6 made of, for example, a synthetic resin is screwed into the rear end side opening 2b of the shaft tube 2, and the knock member 5 is movable in the longitudinal axis KK direction in the hollow space of the tail plug 6. Is held in. In this case, the convex portion 5 b, which is formed substantially in the center of the front end of the knocking member 5 are received within the recess 3c formed substantially in the center of the rear end of the refill 3, whereby the refill 3 and the knocking member 5 Are aligned with each other. In the embodiment according to the present invention, the knock member 5 are aligned substantially central are held by tail plug 6 so as to be located, thus Liffey Le 3 also to be positioned substantially at the center of the refill chamber 2c of the refill chamber 2c. Note that a convex portion may be formed on the refill 3 and a concave portion may be provided on the knock member 5. Further, the knocking member 5 and the rear of the convex portion 5 b flange 5 a is formed an annular between the convex portion 5 b is received in the recess 3c with the rear end of the knocking member 5 and refill 3 A groove 3d is formed.

図3及び図4に示されるように、カバー部材10の前端には開口10dが形成されている。摺動体12はこの開口10を介し前方に延びており、摺動体12の係止突起12aは摺動体室11の外部に位置することになる。なお、係止突起12aはカバー部材10の開口10dよりも大きく寸法設定されている。一方、軸筒2には窓孔2gが形成されており、摺動体12の内向き突起12bはこの窓孔2gを介し内向きに延びてリフィール3とノック部材5との間の環状溝3d内に到り、リフィール3及びノック部材5と係合するようになっている。詳しくは後述するが、内向き突起12bは窓孔2g内を長手軸線K−K方向に移動可能になっている。なお、本発明による実施例では、後方脚10bのための受容孔2eと窓孔2gとが互いに接続されて一つの孔を形成している。更に、クリップ本体7cの係止段部7gに対面する軸筒2に逃げ孔2が形成されている。 As shown in FIGS. 3 and 4, an opening 10 d is formed at the front end of the cover member 10. The sliding body 12 extends forward through the opening 10, and the locking projection 12 a of the sliding body 12 is located outside the sliding body chamber 11. The locking projection 12a is set to be larger than the opening 10d of the cover member 10. On the other hand, the shaft cylinder 2 is formed with a window hole 2g, and the inward projection 12b of the sliding body 12 extends inwardly through the window hole 2g, and is in the annular groove 3d between the refill 3 and the knock member 5. Thus, the refill 3 and the knock member 5 are engaged. Although described later in detail, the inward projection 12b is movable in the longitudinal axis KK direction in the window hole 2g. In the embodiment according to the present invention, the receiving hole 2e for the rear leg 10b and the window hole 2g are connected to each other to form one hole. Furthermore, the hole 2 h escapes into the barrel 2 which faces the step portion 7g of the clip body 7c is formed.

また、本発明による実施例のノック式ボールペン1はいわゆるセーフティ機構を備えている。すなわち、リフィール3が筆記位置にあるときにボールペン1を例えば衣類のポケットに挿すと、クリップ本体7cの係止段部7gと摺動体12の係止突起12aとの間の係止が自動的に解除され、リフィール3が摺動体12及びノック部材5と共に後退位置まで戻され、すなわちペン先3aが軸筒2内に収容される。したがって、衣類がインクで汚れることがない。クリップ本体7cと軸筒2との間に物品を挟もうとした場合も同様である。この場合、クリップ本体7cが外向きに移動してもよいし、クリップ本体7cが外向きに移動しなくても摺動体12の前端部が逃げ孔2内に内向きに変形することによって係止段部7gと係止突起12aとの間の係止が解除される。 The knock ballpoint pen 1 according to the embodiment of the present invention includes a so-called safety mechanism. That is, when the ballpoint pen 1 is inserted into a pocket of clothing, for example, when the refill 3 is in the writing position, the locking between the locking step 7g of the clip body 7c and the locking projection 12a of the sliding body 12 is automatically performed. The refill 3 is returned to the retracted position together with the sliding body 12 and the knock member 5, that is, the pen tip 3 a is accommodated in the shaft tube 2. Therefore, the clothes are not stained with ink. The same applies to an attempt to sandwich an article between the clip body 7c and the shaft cylinder 2. In this case, engagement by clip body 7c is may be moved outwardly, the clip body 7c is deformed inwardly at the front end portion receiving hole 2 in the h of the sliding body 12 without moving outward The locking between the stop portion 7g and the locking projection 12a is released.

次いで、新たなリフィール3が後端側開口2bを介しリフィール室2c内に挿入される。この場合、図8に示されるように摺動体12は離脱位置に保持されている。また、リフィール室2cの内径はリフィール3ないしインクタンク3bの外径よりもわずかに大きく寸法設定されているので(図5参照)、リフィール3はリフィール室2cに対しわずかに偏心した状態でリフィール室2c内を前進させられる。その結果、リフィール3は摺動体12の内向き突起12に衝突することなくリフィール室2c内を前方に移動することができる。 Next, a new refill 3 is inserted into the refill chamber 2c through the rear end side opening 2b. In this case, as shown in FIG. 8, the sliding body 12 is held at the disengaged position. Further, since the inner diameter of the refill chamber 2c is set slightly larger than the outer diameter of the refill 3 or the ink tank 3b (see FIG. 5), the refill chamber 3 is slightly eccentric with respect to the refill chamber 2c. It can be advanced in 2c. As a result, the refill 3 can move forward in the refill chamber 2 c without colliding with the inward projection 12 b of the sliding body 12.

次いで、尾栓6がノック部材5と共に後端側開口2bに取り付けられる。尾栓6が軸筒2に螺合されてノック部材5が前方に移動されると、図7に示されるようにノック部材5の凸部5がリフィール3の凹部3c内に受容されるようになり、したがってリフィール3がリフィール室2c内においてセンタリングされる。また、このときリフィール3とノック部材5との間に環状溝3dが形成される。 Next, the tail plug 6 is attached to the rear end side opening 2 b together with the knock member 5. When tail plug 6 is knocking member 5 is screwed into the barrel 2 is moved forward, so that the convex portion 5 b of the knocking member 5 as shown in FIG. 7 is received in the recess 3c of refill 3 Therefore, the refill 3 is centered in the refill chamber 2c. At this time, an annular groove 3 d is formed between the refill 3 and the knock member 5.
