次に、ロック装置の詳細な構成と作用について説明する。
先ず、天冠７の軸部７ｃ外周に設けられたリブ状の突部７ｄを係止部材８の溝部８ｆに嵌入させて、天冠７と係止部材８が回動方向で一体となされ、その状態で天冠７が後軸２の軸部２ｂに嵌着されて、軸部２ｂの凸部２ｃが天冠７の凹溝７ｂに弾性的に係合し、後軸２に対して天冠７及び係止部材８が回動可能となる。尚、通常ロック装置は、ノック部材６が後軸２に止着された状態で、ノック部材６の係止突起６ａが係止部材８の係止凸部８ａに係合しない位置で取付けられる。（図４参照） Next, the detailed configuration and operation of the locking device will be described.
First, the rib-shaped protrusion 7d provided on the outer periphery of the shaft portion 7c of the crown 7 is fitted into the groove 8f of the locking member 8, and the crown 7 and the locking member 8 are integrated in the rotation direction. In this state, the crown 7 is fitted to the shaft portion 2 b of the rear shaft 2, and the convex portion 2 c of the shaft portion 2 b is elastically engaged with the concave groove 7 b of the crown crown 7, so The crown 7 and the locking member 8 can be rotated. The normal locking device is attached at a position where the locking projection 6 a of the knock member 6 does not engage with the locking projection 8 a of the locking member 8 with the knock member 6 fixed to the rear shaft 2. (See Figure 4)

図１、図２、図３及び図６、図９、図１２は、筆記体９が収納されたされた状態でノック部材６の係止突起６ａが係止部材８の係止凸部８ａに係合する状態となるように示されている。この状態でノック操作しようとしてもノック部材６の前進が係止部材８によって阻止される。
ところで、図１０は図９のＢ−Ｂ断面を示しており、軸筒の軸部２ｂ内孔に設けられたストッパー突部２ｆが係止部材８の規制溝部８ｇに挿入すると共に、規制溝部の一方の段部８ｈに当接し、図７は図６のＡ−Ａ断面を示しており、軸筒の軸部２ｂ内孔に設けられた係止凹部２ｅに係止部材８の係合突部８ｅが係合した状態となってロック装置のロック状態が位置決め固定され、図１３は図１２のＣ−Ｃ断面矢視を示しており、係止部材８の係止突部８ａの後方にノック部材６の係止突起６ａが対接した状態にある。 1, 2, 3, 6, 9, and 12, the locking protrusion 6 a of the knock member 6 is formed on the locking protrusion 8 a of the locking member 8 in a state where the writing body 9 is accommodated. It is shown in an engaged state. Even if the knocking operation is attempted in this state, the advancement of the knocking member 6 is blocked by the locking member 8.
By the way, FIG. 10 shows the BB cross section of FIG. 9, and the stopper protrusion 2f provided in the inner hole of the shaft portion 2b of the shaft tube is inserted into the restriction groove portion 8g of the locking member 8, and FIG. 7 shows an AA cross section of FIG. 6, and the engaging protrusion of the engaging member 8 is engaged with the engaging recess 2 e provided in the inner hole 2 b of the shaft tube. 8e is engaged, and the locking state of the locking device is positioned and fixed. FIG. 13 shows a cross-sectional view taken along the line CC of FIG. The locking projections 6a of the member 6 are in contact with each other.

また、図４には、筆記体９が収納されたされた状態でノック部材６の係止突起６ａが係止部材８の係止凸部８ａから係合解除された状態が示されている。
ところで、図１１はこの係合解除された状態に於ける図９のＢ−Ｂ断面位置に対応した断面を示しており、軸筒の軸部２ｂ内孔に設けられたストッパー突部２ｆが係止部材８の規制溝部８ｇの他方の段部８ｉに当接し、同じく図８は図６のＡ−Ａ断面位置に対応した断面を示しており、軸筒の軸部２ｂ内孔に設けられた係止凹部２ｄに係止部材８の係合突部８ｅが係合した状態となってロック装置のロック解除状態が位置決め固定され、また更に図１４は図１２のＣ−Ｃ断面矢視位置に対応した断面矢視を示しており、係止部材８の係止突部８ａがノック部材６の係止突起６ａが係合を離脱した状態を示している。
尚、ロック装置のロックとロック解除の回動方向は限定されず設定可能である。 4 shows a state in which the engagement protrusion 6a of the knock member 6 is disengaged from the engagement protrusion 8a of the engagement member 8 in a state where the writing body 9 is accommodated.
11 shows a cross section corresponding to the BB cross section position of FIG. 9 in the disengaged state, and the stopper protrusion 2f provided in the inner hole of the shaft portion 2b of the shaft cylinder is engaged. FIG. 8 shows a cross section corresponding to the AA cross section position of FIG. 6 and is provided in the inner hole of the shaft portion 2b of the shaft cylinder. The locking protrusion 8e of the locking member 8 is engaged with the locking recess 2d, and the unlocked state of the locking device is positioned and fixed. Further, FIG. 14 is at the CC cross-sectional arrow position of FIG. The corresponding cross-sectional arrow is shown, and the locking projection 8a of the locking member 8 shows a state in which the locking projection 6a of the knock member 6 is disengaged.
It should be noted that the rotation direction of locking and unlocking the locking device can be set without limitation.

図４の状態から一箇所のノック部材６を前進させ、その筆記体９の先端部を軸先から突出させた状態で、軸筒２に対して天冠７を左に回動すると、ストッパー凸部２ｆが規制溝部８ｇの段部８ｈに当接し、図５に示される状態となる。この状態で他のノック部材６は、その係止突起６ａが係止部材８の係止凸部８ａに係合状態となるので外力が掛かってもノック操作されることも無く、そのために、筆記中に軸先から突出した筆記体の先端部が不用意に没入する問題が防止可能となる。   When the knock member 6 is moved forward from the state of FIG. 4 and the crown portion 7 is rotated to the left with respect to the shaft tube 2 with the tip of the writing body 9 protruding from the shaft tip, The portion 2f comes into contact with the step portion 8h of the restricting groove portion 8g, resulting in the state shown in FIG. In this state, the other knock member 6 has its engaging projection 6a engaged with the engaging projection 8a of the engaging member 8, so that it is not knocked even when an external force is applied. It is possible to prevent a problem that the tip of the cursive projecting from the shaft tip is inadvertently immersed.

上述したロック装置に於いて、軸筒の軸部２ｂ内孔に設けられたストッパー突部２ｆが係止部材８の規制溝部８ｇの段部８ｈと段部８ｉに当接する間の係止部材８即ち天冠７が回動する角度範囲は略４５度となされている。この回動範囲は複式筆記具が３色または４色の筆記体が搭載された場合に適当な範囲であり、従って、回動範囲は搭載される筆記体の数により変動する。
また、ロック装置のロック状態あるいはロック解除状態が明確に位置決めされるように固定され、軸筒の軸部２ｂ内孔に係止凹部２ｅ、２ｄに係止部材８の係合突部８ｅが係合するようになされているが、単に位置決めのためだけでなく、係合部の係脱によるクリック感、クリック音などの効果によりロック操作の操作性を良好とする。また、スリット８ｄは最適なクリック効果を得るために設けられている。
尚、軸筒の係止凹部に係止部材の係合突部が係合する機能は、ロック操作の操作性を良くする上で設けられることが望ましいが、必ず設けなければならないものでもない。
設けない場合には、上述した軸筒の軸部２ｂ内孔に設けられたストッパー突部２ｆが係止部材８の規制溝部８ｇの段部８ｈと段部８ｉに当接する箇所で、相互間に適宜係合する部を設けて位置決め固定できるように容易に設けることが可能である。 In the locking device described above, the locking member 8 while the stopper protrusion 2f provided in the inner hole of the shaft portion 2b of the shaft cylinder abuts on the step portion 8h and the step portion 8i of the restriction groove portion 8g of the locking member 8. That is, the angle range in which the crown 7 rotates is approximately 45 degrees. This rotation range is an appropriate range when the writing instrument of 3 colors or 4 colors is mounted on the compound writing instrument, and therefore the rotation range varies depending on the number of the writing bodies mounted.
The locking device is fixed so that the locked state or unlocked state is clearly positioned, and the engaging protrusion 8e of the engaging member 8 is engaged with the engaging recesses 2e and 2d in the inner hole of the shaft portion 2b of the shaft tube. However, the operability of the lock operation is improved not only for positioning but also by effects such as a click feeling and a click sound due to engagement / disengagement of the engaging portion. The slit 8d is provided to obtain an optimal click effect.
The function of engaging the engaging projection of the locking member with the locking recess of the shaft cylinder is preferably provided to improve the operability of the locking operation, but is not necessarily provided.
When not provided, the stopper protrusion 2f provided in the inner hole of the shaft portion 2b of the shaft cylinder described above is in contact with the step portion 8h and the step portion 8i of the restriction groove portion 8g of the locking member 8, and between them. It is possible to easily provide a portion that is appropriately engaged so that positioning and fixing can be performed.
