Description

本発明は、筆記具に関する。詳細には、前記筆記体を軸筒内に前後方向に移動可能に収容し、前記筆記体のペン先を軸筒の前端孔から出没可能に構成した筆記具に関する。   The present invention relates to a writing instrument. Specifically, the present invention relates to a writing instrument in which the writing body is accommodated in a shaft cylinder so as to be movable in the front-rear direction, and the pen tip of the writing body is configured to be able to appear and retract from a front end hole of the shaft cylinder.

特許文献１には、軸筒内に筆記体を前後方向に移動可能に収容し、軸筒の外面に操作部を設け、前記操作部を操作することにより前記筆記体のペン先を軸筒の前端孔から出没可能に構成し、前記筆記体の内部に熱変色性インキを収容し、前記筆記体の前端に前記熱変色性インキが吐出可能なペン先を設け、前記軸筒の外面に、前記熱変色性インキの筆跡を摩擦しその際に生じる摩擦熱で該筆跡を熱変色可能な摩擦部を設けた熱変色性筆記具が開示されている。   In Patent Document 1, a writing body is accommodated in a shaft cylinder so as to be movable in the front-rear direction, an operation portion is provided on an outer surface of the shaft tube, and the pen tip of the writing body is attached to the shaft tube by operating the operation portion. It is configured to be able to appear and retract from a front end hole, accommodates thermochromic ink inside the cursive body, provides a pen tip capable of ejecting the thermochromic ink at the front end of the cursive body, on the outer surface of the shaft cylinder, There has been disclosed a thermochromic writing instrument provided with a friction portion capable of thermally changing the handwriting with frictional heat generated by rubbing the handwriting of the thermochromic ink.

前記特許文献１は、軸筒後端の操作部を前方に押圧するタイプにおいて操作部に摩擦部を設けた場合、該摩擦部を用いて摩擦操作すると、被筆記面によって操作部が前方に移動し、安定した摩擦操作を行うことができないおそれがある。特に、ペン先突出操作及びペン先没入操作のいずれもが操作部を前方に押圧操作するタイプの出没機構（いわゆるダブルノック式）を採用し且つ操作部に摩擦部を設けた場合、ペン先突出状態において操作体が前後方向にがたつき、安定した摩擦操作を行うことができないおそれがある。   In Patent Document 1, when a friction part is provided in the operation part in the type in which the operation part at the rear end of the shaft cylinder is pressed forward, the operation part moves forward by the writing surface when a friction operation is performed using the friction part. However, there is a possibility that a stable friction operation cannot be performed. In particular, when both a pen tip protruding operation and a pen tip immersing operation employ a retracting mechanism (so-called double knock type) that pushes the operating portion forward and a friction portion is provided in the operating portion, the pen tip protrudes. In this state, the operating body may rattle in the front-rear direction, and a stable friction operation may not be performed.

また、特許文献１の図１２には、筒状の操作部を前後方向に移動可能に設け、前記筒状の操作部の外面にポケット等に挟持可能なクリップを突設し、前記筒状の操作部の後端外面に摩擦部を設けた構成が開示されている。しかし、この構成の熱変色性筆記具は、ペン先の出没操作時に摩擦部を押圧するため、摩擦部が手垢等で汚れるおそれがある。そして、前記摩擦部が汚れた状態で熱変色性インキの筆跡を摩擦した場合、筆跡を有する被筆記面（例えば紙面）が汚れるおそれがある。   Further, in FIG. 12 of Patent Document 1, a cylindrical operation portion is provided so as to be movable in the front-rear direction, and a clip that can be sandwiched in a pocket or the like is provided on the outer surface of the cylindrical operation portion. The structure which provided the friction part in the rear-end outer surface of the operation part is disclosed. However, since the thermochromic writing instrument having this configuration presses the friction portion during the pen tip operation, the friction portion may be soiled with dirt or the like. When the handwriting of the thermochromic ink is rubbed in a state where the friction portion is dirty, the writing surface (for example, paper surface) having the handwriting may be stained.

また、特許文献１の図１５には、操作部を軸筒側壁より径方向外方に突出させ、前記操作部を後方付勢に抗して前方に押圧操作することにより、ペン先没入状態からペン先突出状態にする構成（いわゆる多芯タイプのサイドスライド式）の出没機構を備え、軸筒の後端外面に摩擦部を設けた構成が開示されている。しかし、この構成の熱変色性筆記具は、ペン先突出状態からペン先没入状態にする際（ペン先突出状態を解除する際）、他の筆記体に取り付けられた操作体を操作しなければならない。そのため、複数の操作体（即ち複数の突出部分）を設ける必要があり、外観デザイン上の自由度が減少する。さらには、ポケット等に挟持可能なクリップを軸筒に設ける場合、より一層、突出部分が増え、外観デザイン上の自由度が減少する。   Further, in FIG. 15 of Patent Document 1, the operation portion is protruded radially outward from the side wall of the shaft cylinder, and the operation portion is pushed forward against the rear bias, thereby removing the pen tip from the immersive state. A configuration is disclosed in which a pen tip protruding state (so-called multi-core type side slide type) protruding and retracting mechanism is provided, and a friction portion is provided on the outer surface of the rear end of the shaft cylinder. However, the thermochromic writing instrument with this configuration must operate an operating tool attached to another writing tool when the pen tip protrudes from the pen tip protruding state (when the pen tip protruding state is canceled). . Therefore, it is necessary to provide a plurality of operating bodies (that is, a plurality of protruding portions), and the degree of freedom in appearance design is reduced. Furthermore, when a clip that can be held in a pocket or the like is provided on the shaft tube, the protruding portion is further increased, and the degree of freedom in appearance design is reduced.

Further, the front shaft 3 and the intermediate shaft 4 are detachably connected by screwing, whereby the writing body 9 can be exchanged.

・出没機構
前記出没機構は、回転カム機構を用いたサイドスライド式出没機構である。前記出没機構は、中間軸４内面に形成されたカム部４１に係合し且つ筆記体９の後端に当接する回転部材６と、該回転部材６に係合し且つスライド孔より径方向外方に突出するクリップ体７と、軸筒２内に収容され且つ筆記体９を後方に付勢する弾発体８（例えば圧縮コイルスプリング）とからなる。本実施の形態の出没機構は、ペン先突出操作及びペン先没入操作のいずれもがクリップ体７を前方にスライド操作するダブルノック式である。 -In / out mechanism The in / out mechanism is a side slide type in / out mechanism using a rotating cam mechanism. The retracting mechanism includes a rotating member 6 that engages with a cam portion 41 formed on the inner surface of the intermediate shaft 4 and abuts against the rear end of the writing body 9, and engages with the rotating member 6 and is radially outward from the slide hole. The clip body 7 protrudes in the direction, and the elastic body 8 (for example, compression coil spring) accommodated in the shaft cylinder 2 and biases the writing body 9 backward. The retracting mechanism of the present embodiment is a double knock type in which both the pen tip protruding operation and the pen tip retracting operation slide the clip body 7 forward.

前記カム部４１は、前方に突出する鋸歯状の複数のカム歯４１ａと、該カム歯４１ａ間に形成されるカム溝４１ｂとを備える。前記回転部材６は、その外面に長手方向に延びる４本の突条６１を備え、該突条６１が、カム部４１のカム歯４１ａ及びカム部４１のカム溝４１ｂと係合される。前記クリップ体７の筒状部７３の前端には、回転部材６の突条６１の後端と係合するカム歯７３ａが形成される。   The cam portion 41 includes a plurality of serrated cam teeth 41a protruding forward and a cam groove 41b formed between the cam teeth 41a. The rotating member 6 includes four protrusions 61 extending in the longitudinal direction on the outer surface thereof, and the protrusions 61 are engaged with the cam teeth 41 a of the cam portion 41 and the cam grooves 41 b of the cam portion 41. Cam teeth 73 a that engage with the rear end of the protrusion 61 of the rotating member 6 are formed at the front end of the tubular portion 73 of the clip body 7.

As the ridge 61 of the rotating member 6 moves forward along the cam groove 41 b, the rotating member 6 presses the rear end of the writing body 9 forward, and the pen tip 91 is outside the front end hole 31. Protruding. At this time, the rotating member 6 is rotated by a certain angle with respect to the cam portion 41 by the contact between the cam teeth 73 a of the tubular portion 73 and the protrusion 61 of the rotating member 6. Thereby, the protrusion 61 of the rotating member 6 is engaged with the cam teeth 41a of the cam portion 41, and the pen tip protruding state is maintained.

ペン先突出状態からクリップ体７を前方にスライド操作すると、クリップ体７の筒状部７３が回転部材６を前方に押圧し、前記筒状部７３のカム歯７３ａと前記回転部材６の突条６１との当接によって回転部材６がカム部４１に対して一定角度だけ回転する。それによって、前記突条６１とカム部４１のカム歯４１ａとの係合状態が解除され、弾発体８による後方付勢により、前記突条６１がカム部４１のカム溝４１ｂに沿って後方に移動する。前記回転部材６が後方に移動することに伴って、筆記体９が後方に移動し、ペン先没入状態となる。前記突条６１はカム部４１の後方の段部４２に係止し、ペン先没入状態が維持される。   When the clip body 7 is slid forward from the pen tip protruding state, the cylindrical portion 73 of the clip body 7 presses the rotating member 6 forward, and the cam teeth 73a of the cylindrical portion 73 and the protrusions of the rotating member 6 are pressed. The rotating member 6 rotates by a certain angle with respect to the cam portion 41 by the contact with 61. Accordingly, the engagement state between the protrusion 61 and the cam teeth 41a of the cam portion 41 is released, and the protrusion 61 is rearward along the cam groove 41b of the cam portion 41 due to the rearward biasing by the elastic body 8. Move to. As the rotating member 6 moves rearward, the writing body 9 moves rearward and enters the pen tip immersion state. The protrusion 61 is locked to the stepped portion 42 behind the cam portion 41, and the pen tip immersion state is maintained.

により一体に形成される構成が挙げられる。 -Friction part In this Embodiment, the elastic material which comprises the said friction part 10 has preferable the synthetic resin (rubber, elastomer) which has elasticity, for example, a silicone resin, SBS resin (styrene-butadiene-styrene copolymer) SEBS resin (styrene-ethylene-butadiene-styrene copolymer), fluorine resin, chloroprene resin, nitrile resin, polyester resin, ethylene propylene diene rubber (EPDM), and the like. The elastic synthetic resin constituting the friction part 10 is a low-abrasion elastic material in which almost no wear debris (erasure debris) is generated during friction, compared to a high-abrasion elastic material (for example, an eraser). Preferably it consists of. The friction portion 10 may be provided at least on the outer surface of the rear end portion of the shaft tube 2. For example, the friction portion 10 made of an elastic material is press-fitted, engaged, screwed, and fitted to the rear end portion of the shaft tube 2. In other words, there may be mentioned a structure that is fixed by adhesion, two-color molding or the like, or a structure in which the entire shaft cylinder 2 or the entire rear shaft 5 is integrally formed of an elastic material.

・熱変色性インキ
本実施の形態において、前記熱変色性インキは、可逆熱変色性インキが好ましい。前記可逆熱変色性インキは、発色状態から加熱により消色する加熱消色型、発色状態または消色状態を互変的に特定温度域で記憶保持する色彩記憶保持型、または、消色状態から加熱により発色し、発色状態からの冷却により消色状態に復する加熱発色型等、種々のタイプを単独または併用して構成することができる。 -Thermochromic ink In the present embodiment, the thermochromic ink is preferably a reversible thermochromic ink. The reversible thermochromic ink is a heat decoloring type that decolors by heating from a colored state, a color memory retaining type that reversibly stores and retains a colored state or a decolored state in a specific temperature range, or from a decolored state Various types such as a heating coloring type that develops color by heating and returns to a decolored state by cooling from the colored state can be used alone or in combination.

また、前記可逆熱変色性インキに含有される色材は、従来より公知の（イ）電子供与性呈色性有機化合物、（ロ）電子受容性化合物、及び（ハ）前記両者の呈色反応の生起温度を決める反応媒体、の必須三成分を少なくとも含む可逆熱変色性組成物をマイクロカプセル中に内包させた可逆熱変色性顔料が好適に用いられる。   The coloring material contained in the reversible thermochromic ink includes conventionally known (a) electron donating color-forming organic compounds, (b) electron-accepting compounds, and (c) color reactions of both. A reversible thermochromic pigment in which a reversible thermochromic composition containing at least the essential three components of a reaction medium for determining the occurrence temperature of the polymer is encapsulated in a microcapsule is preferably used.

本実施の形態では、図１０に示すように、温度変化による着色濃度の変化をプロットした曲線の形状が、温度を変色温度域より低温側から上昇させていく場合と逆に変色温度域より高温側から下降させていく場合とで異なる経路を辿って変色し、完全発色温度（ｔ１）以下の低温域での発色状態、または完全消色温度（ｔ４）以上の高温域での消色状態が、特定温度域〔ｔ２〜ｔ３の間の温度域（実質的二相保持温度域）〕で記憶保持できる色彩記憶保持型熱変色性インキが適用されることが好ましい。図１０において、ΔＨは、ヒステリシスの程度を示す温度幅（即ちヒステリシス幅）を示す。ΔＨの値が小さいと、変色前後の両状態のうち一方の状態しか存在しえない。ΔＨの値が大きいと、変色前後の各状態の保持が容易となる。   In the present embodiment, as shown in FIG. 10, the shape of the curve plotting the change in color density due to the temperature change is higher than the color change temperature range, contrary to the case where the temperature is raised from the lower temperature side than the color change temperature range. The color changes by following a different route depending on whether the color is lowered from the side, and a color development state in a low temperature region below the complete color development temperature (t1) or a color erase state in a high temperature region above the complete color removal temperature (t4) It is preferable to apply a color memory retention type thermochromic ink that can be stored and retained in a specific temperature range [temperature range between t2 and t3 (substantially two-phase retention temperature range)]. In FIG. 10, ΔH represents a temperature width (ie, hysteresis width) indicating the degree of hysteresis. When the value of ΔH is small, only one of the two states before and after the color change can exist. When the value of ΔH is large, it is easy to maintain each state before and after the color change.

本実施の形態では、前記熱変色性インキの摩擦部１０の摩擦熱による変色温度は、２５℃〜９５℃（好ましくは３６℃〜９５℃）に設定される。即ち、本実施の形態では、前記高温側変色点〔完全消色温度（ｔ４）〕を、２５℃〜９５℃（好ましくは、３６℃〜９０℃）の範囲に設定し、前記低温側変色点〔完全発色温度（ｔ１）〕を、−３０℃〜＋２０℃（好ましくは、−３０℃〜＋１０℃）の範囲に設定することが有効である。それにより、常態（日常の生活温度域）で呈する色彩の保持を有効に機能させることができるとともに、可逆熱変色性インキによる筆跡を摩擦部１０による摩擦熱で容易に変色することができる。   In the present embodiment, the color change temperature due to frictional heat of the frictional part 10 of the thermochromic ink is set to 25 ° C. to 95 ° C. (preferably 36 ° C. to 95 ° C.). That is, in this embodiment, the high temperature side discoloration point [complete decoloring temperature (t4)] is set in a range of 25 ° C. to 95 ° C. (preferably 36 ° C. to 90 ° C.), and the low temperature side discoloration point is set. It is effective to set [complete color development temperature (t1)] in the range of −30 ° C. to + 20 ° C. (preferably −30 ° C. to + 10 ° C.). Thereby, while maintaining the color exhibited in a normal state (daily life temperature range) can be effectively functioned, the handwriting by the reversible thermochromic ink can be easily changed in color by the frictional heat generated by the friction portion 10.

本実施の形態の熱変色性筆記具１は、少なくとも摩擦操作時に、前記摩擦部１０を軸筒２の後端に固定したことにより、摩擦操作時、摩擦部１０の後方への移動が阻止されるため、摩擦部１０を用いて安定した摩擦操作が可能となる。また、本実施の形態の熱変色性筆記具１は、ペン先９１を出没する際、クリップ体７を操作し、摩擦部１０を操作しないため、摩擦部１０が手垢等で汚れることを回避できる。また、本実施の形態の熱変色性筆記具１は、軸筒２外面にクリップを設けたにもかかわらず、従来の多芯式の熱変色性筆記具に比べ、突出部分が少なく、外観デザイン上の自由度が増加し、スマートな外観を得ることができる。   In the thermochromic writing instrument 1 of the present embodiment, the frictional part 10 is fixed to the rear end of the shaft tube 2 at least during a friction operation, so that the rearward movement of the frictional part 10 is prevented during the friction operation. Therefore, a stable friction operation using the friction part 10 is possible. In addition, since the thermochromic writing instrument 1 of the present embodiment operates the clip body 7 and does not operate the friction part 10 when the pen tip 91 appears and disappears, it can be avoided that the friction part 10 is soiled by hand dirt or the like. In addition, the thermochromic writing instrument 1 of the present embodiment has fewer protruding parts than the conventional multi-core thermochromic writing instrument, despite the provision of a clip on the outer surface of the shaft tube 2, and has an appearance design. The degree of freedom increases and a smart appearance can be obtained.

本実施の形態の熱変色性筆記具１は、出没機構が、回転カム機構を用いたサイドスライド式出没機構であり、ペン先突出操作及びペン先没入操作の何れもがクリップ体７を前方にスライド操作するタイプ（いわゆるダブルノック式の出没機構）であるため、操作方法が簡単であり、ユーザーが操作方法を容易に習得できる。   The thermochromic writing instrument 1 of the present embodiment is a side slide type retracting mechanism in which the retracting mechanism uses a rotating cam mechanism, and both the pen tip protruding operation and the pen tip retracting operation slide the clip body 7 forward. Since it is a type to operate (a so-called double knock type in / out mechanism), the operation method is simple and the user can easily learn the operation method.

本実施の形態の熱変色性筆記具１は、後方に開放された第１の長孔４４と前方に開放された第２の長孔５１とによりスライド孔２１を形成したことによって、クリップ体７をスライド孔２１に容易に挿入することができる。   In the thermochromic writing instrument 1 of the present embodiment, the slide hole 21 is formed by the first long hole 44 opened to the rear and the second long hole 51 opened to the front. It can be easily inserted into the slide hole 21.

本実施の形態の熱変色性筆記具１は、ペン先突出状態を解除しペン先没入状態にする際、弾発体８の後方付勢による筆記体９及びクリップ体７が後方移動し、クリップ体７と弾性材料よりなる摩擦部１０とが当接する。それにより、その際に筆記体９に加わる衝撃が緩和される。その結果、筆記体９内のインキの逆流等やペン先９１からの空気の混入を防止できる。   In the thermochromic writing instrument 1 of the present embodiment, when the pen tip protruding state is released and the pen tip is brought into the pen tip immersing state, the writing body 9 and the clip body 7 due to the rear urging of the projectile 8 move backward, and the clip body 7 and the friction part 10 made of an elastic material come into contact with each other. Thereby, the impact applied to the cursive body 9 at that time is relieved. As a result, it is possible to prevent backflow of ink in the writing body 9 and air from the nib 91.
