従来、胴及びキャップからなる軸筒内にノック式シャープペンシル体を含む複数本の筆記体をコイルスプリングにより軸筒の後端方向に付勢して配設し、キャップを回転することにより任意の筆記体を選択して軸筒の先端より突出させて筆記を行う複合筆記具が知られている。（特許文献１の図４参照）
特公平６−３３０３０号公報 Conventionally, a plurality of writing bodies including a knock-type mechanical pencil body are arranged in a shaft cylinder composed of a cylinder and a cap while being biased by a coil spring in the direction of the rear end of the shaft cylinder, and by rotating the cap, an arbitrary There is known a composite writing instrument in which a writing body is selected and written by protruding from the tip of a shaft cylinder. (See FIG. 4 of Patent Document 1)
Japanese Patent Publication No. 6-33030

しかし、上記した複合筆記具は、キャップを回転させてノック式シャープペンシル体の先端を胴より突出させた筆記状態となった時、ノック式シャープペンシル体の口金に形成された外段が胴の先端部内段とわずかではあるが離間した状態となっている。この状態は、上記した複合筆記具に限らず、複合筆記具においては一般的な筆記状態である。しかし、この状態で筆記を行うと、胴の先端孔内で口金が揺動してしまい、筆記しにくい状態となっていた。また、芯を繰り出す為にキャップを押圧した場合には、口金の外段を胴の内段に当接した後に芯を繰り出す為に、キャップを押圧する毎に口金が前進してしまい、使用者に不快感を与えてしまう問題があった。   However, when the above-mentioned composite writing instrument is in a writing state in which the tip of the knock-type mechanical pencil body is projected from the body by rotating the cap, the outer stage formed on the base of the knock-type mechanical pencil body is the tip of the body It is slightly separated from the internal stage. This state is not limited to the above-described composite writing instrument, and is a general writing state in the composite writing instrument. However, when writing is performed in this state, the base swings in the front end hole of the barrel, which makes writing difficult. In addition, when the cap is pressed to extend the core, the base moves forward each time the cap is pressed to extend the core after the outer stage of the base comes into contact with the inner stage of the body, and the user moves forward. There was a problem that made it uncomfortable.

本発明は、上記課題を解消する複合筆記具を提供することを目的とするものである。   An object of this invention is to provide the composite writing instrument which eliminates the said subject.

本発明は、軸筒内にシャープペンシル体を含む複数本の筆記体を配設し、任意の筆記体を出没手段により選択して軸筒の先端より突出させ筆記を行う複合筆記具において、チャックの頭部に締具を外嵌し、チャックの後部に固着されたコネクターと連結具の間にチャックスプリングを張架し、チャックを後方に付勢することによりチャックの頭部が締具に押圧されるとともに、締具が連結具に押圧されてチャックが閉じられ芯を強く保持し、前部に口金を取り付けた連結具に外パイプを着脱可能に取り付け、更に、外パイプ内に押圧部材を長手方向に摺動可能に内蔵し、前記押圧部材に芯タンクを固着し、外パイプと芯タンクの間に筆圧より強い力で筆圧スプリングを張架し、コネクターと押圧部材を適宜離間してシャープペンシル体を構成するとともに、前記芯タンクを出没手段に連結し、シャープペンシル体の口金を軸筒の先端より突出させた時、口金の外段が軸筒の内段に当接し、筆圧スプリングを圧縮させてシャープペンシル体を筆記状態とし、この筆記状態で、筆記を行う時あるいは芯タンクを前進させることにより押圧部材がコネクターに当接してチャックを前進させ芯を繰り出す時に、口金の揺動を防止することを第１の要旨とする。   The present invention provides a composite writing instrument in which a plurality of writing bodies including a mechanical pencil body are arranged in a shaft cylinder, and an arbitrary writing body is selected by a retracting means so that the writing is performed by projecting from the tip of the shaft cylinder. A fastener is fitted on the head, a chuck spring is stretched between the connector fixed to the rear of the chuck and the coupling tool, and the chuck head is pressed against the fastener by urging the chuck backward. At the same time, the fastener is pressed by the connector, the chuck is closed, the core is held firmly, the outer pipe is detachably attached to the connector with the base attached to the front part, and the pressing member is elongated in the outer pipe. It is slidably built in the direction, a core tank is fixed to the pressing member, a writing pressure spring is stretched between the outer pipe and the core tank with a force stronger than the writing pressure, and the connector and the pressing member are separated appropriately. Construct mechanical pencil body In addition, when the lead tank is connected to the retracting means and the base of the mechanical pencil body is protruded from the tip of the shaft cylinder, the outer stage of the base comes into contact with the inner stage of the shaft cylinder, and the writing pressure spring is compressed. With the mechanical pencil body in the writing state, when the writing is performed in this writing state or when the lead tank is advanced, the pressing member comes into contact with the connector and the chuck is moved forward to prevent the base from swinging. Is the first gist.

また、軸筒内にシャープペンシル体を含む複数本の筆記体を配設し、任意の筆記体を出没手段により選択して軸筒の先端より突出させ筆記を行う複合筆記具において、チャックの頭部に締具を外嵌し、チャックの後部に固着されたコネクターと連結具の間にチャックスプリングを張架し、チャックを後方に付勢することによりチャックの頭部が締具に押圧されるとともに、締具が連結具に押圧されてチャックが閉じられ芯を強く保持し、前部に口金を取り付けた連結具内に押圧部材を長手方向に摺動可能に内蔵し、前記押圧部材に芯タンクを着脱可能に取り付け、連結具と押圧部材の間に筆圧より強い力で筆圧スプリングを張架し、コネクターと押圧部材を適宜離間してシャープペンシル体を構成するとともに、前記芯タンクを出没手段に連結し、シャープペンシル体の口金を軸筒の先端より突出させた時、口金の外段が軸筒の内段に当接し、筆圧スプリングを圧縮させてシャープペンシル体を筆記状態とし、この筆記状態で、筆記を行う時あるいは芯タンクを前進させることにより押圧部材がコネクターに当接してチャックを前進させ芯を繰り出す時に、口金の揺動を防止することを第２の要旨とする。   Further, in a composite writing instrument in which a plurality of writing bodies including a mechanical pencil body are arranged in a shaft cylinder, and an arbitrary writing body is selected by a retracting means to project from the tip of the shaft cylinder, the head of the chuck The fastener is externally fitted to the chuck, a chuck spring is stretched between the connector fixed to the rear part of the chuck and the coupling tool, and the chuck head is pressed against the fastener by urging the chuck backward. The fastener is pressed by the connecting tool, the chuck is closed and the lead is strongly held, and a pressing member is slidably incorporated in the connecting member with a base attached to the front part, and the lead tank is provided in the pressing member. The pen pressure spring is stretched between the connector and the pressing member with a force stronger than the pen pressure, and the connector and the pressing member are separated from each other to form a mechanical pencil body. Relevance to means When the mechanical pencil base is protruded from the tip of the shaft tube, the outer stage of the base comes into contact with the inner stage of the shaft cylinder and the writing pressure spring is compressed to make the mechanical pencil body in the writing state. Therefore, the second gist is to prevent the cap from swinging when writing or when the pressing member abuts on the connector by moving the lead tank forward to advance the chuck to feed the lead.

更に、軸筒の内段をテーパー状に形成するとともに、前記軸筒の内段に当接される口金の外段をテーパー状に形成したことを第３の要旨とする。   Further, the third aspect is that the inner stage of the shaft tube is formed in a taper shape, and the outer stage of the base abutted on the inner stage of the shaft tube is formed in a taper shape.

更にまた、軸筒を構成する前軸に金属製の先金を取り付け、口金の外段に当接される内段を先金に形成したことを第４の要旨とする。   Furthermore, a fourth gist is that a metal tip is attached to the front shaft constituting the shaft cylinder, and an inner stage that contacts the outer stage of the base is formed on the tip.

本発明の複合筆記具は、シャープペンシル体の口金を軸筒の先端より突出して筆記状態とした時、口金の外段を軸筒の内段に当接させているので、筆記を行う時や、芯タンクを前進させて芯を繰り出す時に、口金が揺動しないという効果が奏せられるものである。   The composite writing instrument of the present invention has a mechanical pencil body that protrudes from the tip of the shaft tube in a writing state, and since the outer stage of the mouthpiece is in contact with the inner stage of the shaft tube, when writing, When the lead tank is advanced and the lead is drawn out, the effect that the base does not swing is exhibited.

芯タンクを前進させてシャープペンシル体の口金を軸筒の先端より突出させた時、口金が軸筒の径方向及び長手方向に揺動しない複合筆記具を実現した。   When the lead tank is advanced and the base of the mechanical pencil body is projected from the tip of the shaft tube, a composite writing instrument is realized in which the base does not swing in the radial direction and the longitudinal direction of the shaft tube.

以下、図１に基づいて本発明における実施例１の複合筆記具に用いるシャープペンシル体を説明する。また、図１の左側を前方とし、右側を後方とする。先ず、前部を複数に分割して拡開可能なチャック１の頭部１Ａに締具２を外嵌し、このチャック１の後部に合成樹脂製のコネクター３を圧入固着する。また、連結具４の内段４Ａとコネクター３の前端との間にチャックスプリング５を２００ｇ程度の力で張架し、チャック１に外嵌された締具２を連結具４の前端に当接してチャック１が閉じられ、チャック１により芯６が保持される。この連結具４の前部には、口金７が螺合あるいは圧入により取り付けられ、更に、口金７内に芯６を適度の力で保持するゴム製の芯ホルダー８が取り付けられている。   Hereinafter, the mechanical pencil body used for the composite writing instrument of Example 1 in this invention is demonstrated based on FIG. Moreover, let the left side of FIG. 1 be the front, and let the right side be back. First, a fastener 2 is externally fitted to the head 1A of the chuck 1 which can be expanded by dividing the front part into a plurality of parts, and a connector 3 made of synthetic resin is press-fitted and fixed to the rear part of the chuck 1. Further, a chuck spring 5 is stretched between the inner stage 4A of the connector 4 and the front end of the connector 3 with a force of about 200 g, and the fastener 2 externally fitted to the chuck 1 is brought into contact with the front end of the connector 4. The chuck 1 is closed, and the lead 6 is held by the chuck 1. A base 7 is attached to the front portion of the connector 4 by screwing or press fitting, and a rubber core holder 8 for holding the core 6 with an appropriate force is attached in the base 7.

また、前記連結具４には外パイプ９が着脱可能に嵌合されて連結される。この外パイプ９内には押圧部材１０が長手方向に摺動可能に内蔵され、押圧部材１０の後部には芯タンク１１が固着される。更に、芯タンク１１の前端外鍔１１Ａと外パイプ９の後端内鍔９Ａの間には、筆圧より強い５００ｇ程度の力で筆圧スプリング１２が張架され、コネクター３の後端と押圧部材１０の前端とは適宜離間して構成される。前記芯タンク１１内に予備の芯６が収納されてシャープペンシル体が構成される。   An outer pipe 9 is detachably fitted to and connected to the connector 4. A pressing member 10 is built in the outer pipe 9 so as to be slidable in the longitudinal direction, and a core tank 11 is fixed to the rear portion of the pressing member 10. Further, a pen pressure spring 12 is stretched between the front end outer rod 11A of the lead tank 11 and the rear end inner rod 9A of the outer pipe 9 with a force of about 500 g stronger than the pen pressure. The front end of the member 10 is appropriately separated from the front end. A spare lead 6 is housed in the lead tank 11 to form a mechanical pencil body.

上記シャープペンシル体は、外パイプ９、押圧部材１０、筆圧スプリング１２及び芯タンク１１が複合筆記具の出没手段に連結されており、芯タンク１１内に芯６を補充する場合には、外パイプ９から連結具４を外して補充する。   In the mechanical pencil body, the outer pipe 9, the pressing member 10, the writing pressure spring 12, and the lead tank 11 are connected to the protruding and retracting means of the composite writing instrument, and when the lead 6 is refilled in the lead tank 11, the outer pipe 9 to remove the connector 4 and refill.

上記シャープペンシル体は従来知られている種々の複合筆記具に連結可能であるが、例えば図２に示した振子式の複合筆記具に連結可能である。後軸１３内に内軸１４を固着し、内軸１４には２つの摺動孔１４Ａ、１４Ｂが並設されている。この摺動孔１４Ａ、１４Ｂは、それぞれ側面に開口した窓が形成され、この窓から駒１５及び摺動部材１６が挿入される。前記摺動孔１４Ａにはシャープペンシル体の芯タンク１１が長手方向に摺動可能に内蔵され、この芯タンク１１の後端に駒１５が固着される。摺動孔１４Ｂには摺動部材１６が長手方向に摺動可能に内蔵され、この摺動部材１６にボールペンレフィール１７が着脱可能に保持される。   The mechanical pencil body can be connected to various known composite writing instruments. For example, the mechanical pencil body can be connected to a pendulum composite writing instrument shown in FIG. An inner shaft 14 is fixed inside the rear shaft 13, and two sliding holes 14 </ b> A and 14 </ b> B are arranged in parallel on the inner shaft 14. Each of the sliding holes 14A and 14B is formed with a window opened on a side surface, and the piece 15 and the sliding member 16 are inserted through the window. A mechanical pencil core tank 11 is slidably incorporated in the sliding hole 14A in the longitudinal direction, and a piece 15 is fixed to the rear end of the core tank 11. A sliding member 16 is built in the sliding hole 14B so as to be slidable in the longitudinal direction, and a ballpoint pen refill 17 is detachably held by the sliding member 16.

次に、それぞれの摺動孔１４Ａ、１４Ｂの前部に形成した内鍔と駒１５および摺動部材１６との間にはリターンスプリング１８が張架され、駒１５および摺動部材１６を長手方向後方に付勢している。更に、後軸１３内には押具１９が長手方向に摺動可能でかつ回動不能に内蔵され、前記内軸１４の後端と押具１９の外段１９Ａとの間に張架された後スプリング２０により押具１９が後方に付勢されている。押具１９の前部には振子２１が重力により揺動可能に設けられ、押具１９の後部内側には消しゴム２２が嵌合される。また、押具１９の後部外側にはノブ２３が嵌合される。押具１９の周面上部より掘られた固定穴１９Ｂにコイルスプリング２４により後軸１３の周面外側に付勢されて係止具２５が設けられ、係止具２５の上面が後軸１３の内面に当接されている。   Next, a return spring 18 is stretched between the inner flange formed at the front part of each sliding hole 14A, 14B, the piece 15 and the sliding member 16, and the piece 15 and the sliding member 16 are moved in the longitudinal direction. It is energized backward. Further, a pusher 19 is built in the rear shaft 13 so as to be slidable in the longitudinal direction and not rotatable, and is stretched between the rear end of the inner shaft 14 and the outer stage 19A of the pusher 19. The pusher 19 is urged rearward by the rear spring 20. A pendulum 21 is provided at the front portion of the pressing tool 19 so as to be swingable by gravity, and an eraser 22 is fitted inside the rear portion of the pressing tool 19. In addition, a knob 23 is fitted to the outside of the rear portion of the pressing tool 19. The fixing hole 19B dug from the upper part of the peripheral surface of the pressing tool 19 is urged to the outer peripheral surface of the rear shaft 13 by the coil spring 24 to provide the locking tool 25, and the upper surface of the locking tool 25 is the upper surface of the rear shaft 13. It is in contact with the inner surface.

更に、内軸１４には前軸２６が着脱可能に螺合されて、前軸２６と後軸１３により軸筒が構成される。また、前軸２６には先端開口孔２６Ａが形成され、この先端開口孔２６Ａより後方に伸びてテーパー状の内段２６Ｂを形成する。尚、図示してないが後軸に前軸を着脱可能に螺合し、軸筒を構成してもよい。   Further, a front shaft 26 is detachably screwed to the inner shaft 14, and a shaft cylinder is constituted by the front shaft 26 and the rear shaft 13. Further, the front shaft 26 is formed with a front end opening hole 26A and extends rearward from the front end opening hole 26A to form a tapered inner step 26B. Although not shown, the shaft may be configured by screwing the front shaft detachably with the rear shaft.

次に、シャープペンシル体を出没させる操作を説明する。前記した図２の没入状態より先ずシャープペンシル体を突出させるには、軸筒を傾けてシャープペンシル体の芯タンク１１に連結された駒１５側に振子２１を寄せる。その後、軸筒の後端より突出したノブ２３を押圧して、振子２１を駒１５に当接する。更にノブ２３を押圧すると、押具１９、振子２１、駒１５およびシャープペンシル体が前進し、シャープペンシル体の口金７を前軸２６の先端開口孔２６Ａより突出させて口金７の外段７Ａが前軸２６の内段２６Ｂに当接し、筆圧スプリング１２を圧縮させる。更にノブ２３を押圧すると、係止具２５が後軸１３の開口窓１３Ａに係止され、図３、図４および図５に示した筆記状態となる。従って、筆記状態では口金７の外段７Ａが前軸２６の内段２６Ｂに当接されているので、口金７は揺動することなく筆記が行える。また、コネクター３の後端と押圧部材１０の前端は適宜離間している。   Next, an operation for causing the mechanical pencil body to appear and disappear will be described. In order to first project the mechanical pencil body from the above-described immersion state of FIG. 2, the pendulum 21 is moved toward the piece 15 connected to the core tank 11 of the mechanical pencil body by tilting the shaft cylinder. Thereafter, the knob 23 protruding from the rear end of the shaft cylinder is pressed to bring the pendulum 21 into contact with the piece 15. When the knob 23 is further pressed, the pusher 19, the pendulum 21, the piece 15, and the mechanical pencil body move forward, and the base 7 of the mechanical pencil body protrudes from the tip opening hole 26A of the front shaft 26 so that the outer stage 7A of the base 7 is moved. Abutting on the inner stage 26B of the front shaft 26, the writing pressure spring 12 is compressed. When the knob 23 is further pressed, the locking tool 25 is locked to the opening window 13A of the rear shaft 13, and the writing state shown in FIGS. 3, 4, and 5 is obtained. Accordingly, since the outer stage 7A of the base 7 is in contact with the inner stage 26B of the front shaft 26 in the writing state, the base 7 can perform writing without swinging. Further, the rear end of the connector 3 and the front end of the pressing member 10 are appropriately separated.

この状態で筆記を行い、芯６が消耗した場合には、ノブ２３を押圧して押具１９及び振子２１を前進させ、振子２１に当接された駒１５および芯タンク１１を前進させる。すると、芯タンク１１の前部に固着された押圧部材１０が前進し、押圧部材１０がコネクター３に当接される。コネクター３が前進させられるとチャック１も前進させられ、チャック１に保持された芯６が一定量繰り出される。   When writing is performed in this state and the lead 6 is consumed, the knob 23 is pressed to advance the pusher 19 and the pendulum 21, and the piece 15 and the lead tank 11 in contact with the pendulum 21 are advanced. Then, the pressing member 10 fixed to the front portion of the lead tank 11 moves forward, and the pressing member 10 comes into contact with the connector 3. When the connector 3 is advanced, the chuck 1 is also advanced, and the core 6 held by the chuck 1 is fed out by a certain amount.

シャープペンシル体を没入させるには、クリップ２７を押圧することによりクリップ２７の受部２７Ａで係止具２５を押圧し、係止具２５を後軸１３の開口窓１３Ａより外す。すると、後スプリング２０により後方に付勢されて押具１９が後退し、押具１９の後部外段１９Ｃが後軸１３の内段１３Ｂに当接される。また、シャープペンシル体に連結された駒１５はリターンスプリング１８により後方に付勢され、駒１５が内軸１４の後部内段１４Ｃに当接され図２の状態に復帰する。   In order to immerse the mechanical pencil body, by pressing the clip 27, the locking tool 25 is pressed by the receiving portion 27 </ b> A of the clip 27, and the locking tool 25 is removed from the opening window 13 </ b> A of the rear shaft 13. Then, the pusher 19 is urged rearward by the rear spring 20, and the rear outer stage 19 </ b> C of the pusher 19 comes into contact with the inner stage 13 </ b> B of the rear shaft 13. Further, the piece 15 connected to the mechanical pencil body is urged rearward by the return spring 18, and the piece 15 comes into contact with the rear inner stage 14C of the inner shaft 14 to return to the state shown in FIG.

また、ボールペン体を使用する場合には、シャープペンシル体を突出させた時と逆側に軸筒を傾け、振子２１を摺動部材１６側に位置させる。そしてノブ２３を押圧すれば、ボールペンレフィール１７が前軸２６の先端開口孔２６Ａより突出する。次に、クリップ２７を押圧して係止具２５を後軸１３の開口窓１３Ａより外せば、ボールペンレフィール１７は没入し図２の状態に復帰する。   When using a ball-point pen body, the shaft cylinder is tilted to the opposite side to when the mechanical pencil body is protruded, and the pendulum 21 is positioned on the sliding member 16 side. When the knob 23 is pressed, the ballpoint refill 17 protrudes from the tip opening hole 26A of the front shaft 26. Next, when the clip 27 is pressed to remove the locking tool 25 from the opening window 13A of the rear shaft 13, the ballpoint pen refill 17 is immersed and returns to the state shown in FIG.

以下、図６および図７に基づいて本発明における実施例２の複合筆記具に用いるシャープペンシル体を説明する。尚、図１と同一部材は同一の符号を付してその説明を省略する。連結具１０４の内段１０４Ａとコネクター３の段部との間にチャックスプリング５を２００ｇ程度の力で張架し、チャック１に外嵌された締具２を連結具１０４の前端に当接してチャック１が閉じられ、チャック１により芯６が保持される。連結具１０４の上下には係止窓１０４Ｂが互いに対向して形成される。押圧部材１１０の前部外面には係止突起１１０Ａが上下に対向して形成され、この係止突起１１０Ａは前端が傾斜されて形成されるとともに後端は垂直に形成される。更に、押圧部材１１０の前部には両端に互いに対向して開口窓１１０Ｂが形成され、押圧部材１１０の前部が撓み可能に構成される。   Hereinafter, the mechanical pencil body used for the composite writing instrument of Example 2 in this invention is demonstrated based on FIG. 6 and FIG. In addition, the same member as FIG. 1 attaches | subjects the same code | symbol, and abbreviate | omits the description. A chuck spring 5 is stretched between the inner step 104A of the connector 104 and the step of the connector 3 with a force of about 200 g, and the fastener 2 fitted on the chuck 1 is brought into contact with the front end of the connector 104. The chuck 1 is closed and the lead 6 is held by the chuck 1. Locking windows 104B are formed on the upper and lower sides of the connector 104 so as to face each other. A locking protrusion 110A is formed on the outer surface of the front portion of the pressing member 110 so as to face the upper and lower sides. The locking protrusion 110A is formed with an inclined front end and a rear end formed vertically. Furthermore, opening windows 110B are formed at both ends of the front portion of the pressing member 110 so as to be opposed to each other, and the front portion of the pressing member 110 is configured to be deflectable.

It is slidably connected in the longitudinal direction. Further, a writing pressure spring 12 is stretched between the rear end of the connector 104 and the outer casing 110 </ b> C of the pressing member 110 with a force of about 500 g stronger than the writing pressure, and the rear end of the connector 3 and the pressing member 110. It is configured to be appropriately separated from the front end. A core tank 111 is detachably fitted to the rear portion of the pressing member 110. A spare lead 6 is stored in the lead tank 111 to form a mechanical pencil body.

上記シャープペンシル体は、芯タンク１１１のみが複合筆記具の出没手段に連結され、芯タンク１１１内に芯６を補充する場合には、芯タンク１１１から押圧部材１１０を外して補充する。   In the mechanical pencil body, only the lead tank 111 is connected to the in / out means of the composite writing instrument, and when the lead 6 is refilled in the lead tank 111, the press member 110 is removed from the lead tank 111 for refilling.

図８に基づいて本発明における実施例３の複合筆記具を説明する。尚、図１と同一部材は同一の符号を付してその説明を省略する。合成樹脂製の前軸１２６に金属製の先金２８を螺合等により取り付ける。この先金２８に先端開口孔２８Ａおよびテーパー状の内段２８Ｂを形成する。   Based on FIG. 8, the composite writing instrument of Example 3 in this invention is demonstrated.
