Description

本発明は、ペン先の突出構造に関する。  The present invention relates to a protruding structure of a pen tip.

特開２００５−１２５５８９  JP-A-2005-125589

操作部を軸筒後方に向け移動させることによりペン先を突出させる構造の筆記具としては、特許文献１に示すようなタイプのものがある。しかし、この構造では蛍光ペンのように蓋が必要な筆記具の場合、移動するペン先が開放前の蓋と接触しないようにするためには、ペン先を筆記具本体内部においてある程度奥の位置からスタートさせなければならない。だが操作部とペン先の移動距離の比率が１：１の構造では、例えば操作部を筆記具の前部に設け、持ち手の一指にて操作を行うものとする場合、使用者が快適に行える操作の量では快適な筆記に必要なだけのペン先の露出量を得ることは困難である。  As a writing instrument having a structure in which the pen tip protrudes by moving the operation unit toward the rear of the shaft cylinder, there is a type as shown in Patent Document 1. However, in this structure, in the case of a writing instrument that requires a lid, such as a fluorescent pen, to prevent the moving pen tip from coming into contact with the lid before opening, the pen tip is started from a certain depth inside the writing instrument body. I have to let it. However, when the ratio of the moving distance between the operation unit and the pen tip is 1: 1, for example, when the operation unit is provided at the front of the writing instrument and the operation is performed with one finger of the handle, the user can comfortably With the amount of operations that can be performed, it is difficult to obtain the amount of nib exposure necessary for comfortable writing.

本発明は、上記課題を解決するためになされたものであり、まず請求項１の発明では、先端が開口した軸筒の内部に納められたペン先が、軸筒に設けた操作部を操作することにより軸筒先端開口部より突出する筆記具において、該操作部に動滑車を設け、該軸筒または該軸筒と一体の部材上へ固定滑車を設け、一端が該軸筒または該軸筒と一体の部材上へ取り付けられた糸状部材が、該動滑車に掛けられ、そこから該固定滑車へと掛けられ、残りの一端を、先端に該ペン先を有する芯材へと取り付けられた構造で、動滑車の働きにより、該操作部の操作距離を上回る距離を該ペン先が移動するようにしたことを特徴とする筆記具を提供する。  SUMMARY OF THE INVENTION The present invention has been made to solve the above problems. First, in the invention of claim 1, a pen tip housed in a shaft cylinder having an open end operates an operation section provided on the shaft cylinder. In the writing instrument that protrudes from the opening at the tip of the shaft tube, a moving pulley is provided at the operation portion, a fixed pulley is provided on the shaft tube or a member integral with the shaft tube, and one end is the shaft tube or the shaft tube A structure in which a thread-like member mounted on a member integral with the hook is hung on the movable pulley, hung on the fixed pulley, and the other end is attached to a core member having the nib at the tip. Thus, a writing instrument is provided in which the pen tip moves a distance exceeding the operation distance of the operation unit by the action of the movable pulley.

また請求項２の発明では、該操作部に連結された蓋部材が、その操作部の動きに連動し、該ペン先が突出入する孔の開放及び閉塞を行うことを特徴とした筆記具を提供する。  According to a second aspect of the present invention, there is provided a writing instrument characterized in that the lid member connected to the operation portion opens and closes the hole into which the pen tip protrudes in conjunction with the movement of the operation portion. To do.

また請求項３の発明では、該ペン先単体、または、該ペン先と該芯材が一体で回動自在に軸筒１内部に設置され、その回動が適当な角度において系止され、その角度を維持したまま軸筒先端開口部より突出し筆記することが可能な構造としたことを特徴とする筆記具を提供する。  Further, in the invention of claim 3, the pen nib or the pen nib and the core are integrally installed in the shaft cylinder 1 so as to freely rotate, and the rotation is stopped at an appropriate angle. Provided is a writing instrument characterized in that it has a structure that protrudes from a tip end opening portion of a shaft cylinder and can be written while maintaining an angle.

また請求項４の発明では、該ペン先が該軸筒先端より露出した状態、すなわち筆記可能な状態に該ペン先を系止する機能を備えたことを特徴とする筆記具を提供する。  According to a fourth aspect of the present invention, there is provided a writing instrument comprising a function of stopping the pen tip in a state where the pen tip is exposed from the tip of the shaft cylinder, that is, a state where writing is possible.

また請求項５の発明では、該ペン先が該軸筒先端より突出しないよう、該ペン先を該軸筒内に系止する機能を備えたことを特徴とする筆記具を提供する。  According to a fifth aspect of the present invention, there is provided a writing instrument having a function of stopping the pen tip in the shaft tube so that the pen tip does not protrude from the tip of the shaft tube.

なお、請求項１の発明を詳細に説明すると次のとおりである。文中の「軸筒」の断面形状は円形状以外であってもよい。また該軸筒において、ペン先が突出する側を前方とする。そして前方に位置する端を軸筒先端とする。また、文中の「動滑車の働き」とは、すなわち、一つの動滑車を用いた場合、動滑車にかかる力は２倍になる代わりに、動滑車の移動距離は２分の一になるといった原理を応用したものである。  The invention of claim 1 will be described in detail as follows. The cross-sectional shape of the “shaft cylinder” in the sentence may be other than a circular shape. Further, in the shaft tube, the side from which the pen tip projects is the front. And let the edge located ahead be a shaft cylinder tip. Also, the “moving pulley function” in the sentence means that when a single moving pulley is used, instead of doubling the force applied to the moving pulley, the moving distance of the moving pulley is halved. It is an application of the principle.

請求項２の発明を詳細に説明すると次のとおりである。文中の「ペン先が突出入する孔」とは、軸筒の先端に位置する孔、または軸筒内部におけるペン先の通る軸孔について述べたものである。  The invention of claim 2 will be described in detail as follows. The term “hole into which the pen tip protrudes” in the text refers to a hole located at the tip of the shaft tube or a shaft hole through which the pen tip passes.

請求項３の発明を詳細に説明すると次のとおりである。例えば蛍光ペンのように先端が斜めにカットされたペン先を持つ筆記具などは、縦書きと横書きとではペン先の上下の向きを変えなければならない。本請求項の発明は、そのような状況に対応可能な筆記具を提供するための発明であり、文中で述べた「回動」および、「適当な角度において系止」とは、例えば図７と図８とにより示したような状態の変化をもたらすものである。  The invention of claim 3 will be described in detail as follows. For example, a writing instrument having a nib whose tip is cut obliquely, such as a highlighter pen, must change the vertical direction of the nib between vertical writing and horizontal writing. The invention of this claim is an invention for providing a writing instrument that can cope with such a situation, and “rotation” and “system stop at an appropriate angle” described in the text are, for example, as shown in FIG. The change of the state as shown in FIG. 8 is brought about.

動滑車の作用により、ペン先の移動距離は操作部のスライド距離を上回るものとなる。その結果、操作量を増やすことなくペン先の待機位置を軸筒内のより奥の方に設定することが可能となり、蓋部材とペン先との接触の危険性が小さくなるため、蓋部材の構造を考える上で有利である。  Due to the action of the moving pulley, the moving distance of the pen tip exceeds the sliding distance of the operation unit. As a result, it becomes possible to set the standby position of the pen tip further in the shaft cylinder without increasing the operation amount, and the risk of contact between the lid member and the pen tip is reduced. This is advantageous in considering the structure.

本実施例による筆記具は、軸筒１、芯材２、ペン先３、操作部４ａ、動滑車５、固定滑車６、糸状部材７、前方ガイド８、シーリング９、蓋部材１０、中央ガイド１１、コイルばね１２、芯材後部１３、角度固定具１４、角度調整溝１５、インクカートリッジ１６により構成される。なお操作部４ａは、本筆記具を服のポケットなどに差し込む際に利用するクリップの機能を兼ね備えたものとなっている。（図１参照）  The writing instrument according to the present embodiment includes a shaft cylinder 1, a core material 2, a pen tip 3, an operation unit 4a, a moving pulley 5, a fixed pulley 6, a thread-like member 7, a front guide 8, a sealing 9, a lid member 10, a central guide 11, The coil spring 12, the core material rear portion 13, the angle fixing tool 14, the angle adjustment groove 15, and the ink cartridge 16 are configured. The operation unit 4a has a function of a clip used when the writing instrument is inserted into a pocket of clothes. (See Figure 1)

軸筒１先端内部に、前方ガイド８を取り付け、前方ガイド８上に固定滑車６を軸着する。軸筒１には、操作部用スリット１７を開け、その操作部用スリット１７を利用して操作部４ａを装着する。（図３、図４参照）操作部４ａにおいて軸筒１内に位置する場所に、動滑車５を軸着する。  A front guide 8 is attached inside the tip of the shaft tube 1, and a fixed pulley 6 is pivotally mounted on the front guide 8. An operating portion slit 17 is opened in the shaft cylinder 1, and the operating portion 4 a is mounted using the operating portion slit 17. (Refer FIG. 3, FIG. 4) The movable pulley 5 is axially attached to the location located in the axial cylinder 1 in the operation part 4a.

先端にペン先３を備えた芯材２は、その表面が薄く硬質な素材に覆われており、前方ガイド８と中央ガイド１１とにより支持され、コイルばね１２により軸筒後方に向け押止される。また、芯材後部１３は軸筒１の内径よりわずかに小さな径を持ち、その表面には角度固定用溝１５が長手方向に刻まれている。そして、角度固定具１４の内側突起部分が、軸筒１に開けた角度調整用スリット１８を通し、軸筒１内にて角度固定用溝１５に収まるよう角度固定具１４を軸筒１上に嵌める。なお、角度調整用スリット１８は、角度固定具１４の内側突起部分がほぼ９０度の範囲を移動できる長さに設けるのがよい。（図４から図６参照）  The core material 2 provided with the pen tip 3 at the tip is covered with a thin and hard material, supported by the front guide 8 and the center guide 11, and pressed against the rear of the shaft cylinder by the coil spring 12. The The core rear portion 13 has a diameter slightly smaller than the inner diameter of the shaft tube 1, and an angle fixing groove 15 is engraved in the longitudinal direction on the surface. Then, the angle fixing tool 14 is placed on the shaft cylinder 1 so that the inner protruding portion of the angle fixing tool 14 passes through the angle adjusting slit 18 opened in the shaft cylinder 1 and fits in the angle fixing groove 15 in the shaft cylinder 1. Fit. The angle adjusting slit 18 is preferably provided in such a length that the inner protrusion of the angle fixing tool 14 can move within a range of approximately 90 degrees. (See FIGS. 4 to 6)

蓋部材１０は、操作部４ａから前方に向かって延びた状態で、その先端に近い部分は薄くある程度の柔軟性を持ったものとする。そして、前方ガイド８表面と軸筒１内面とにより形成されたガイドとなる薄い空間に沿って操作部４ａの動きに併せて移動し、前方ガイド８の軸孔の先端を塞いだり開放したりできるように設置する。（図１、図２参照）  The lid member 10 extends forward from the operation portion 4a, and the portion near the tip is thin and has a certain degree of flexibility. And it moves according to the movement of the operation part 4a along the thin space used as the guide formed by the front guide 8 surface and the shaft cylinder 1 inner surface, and the front end of the shaft hole of the front guide 8 can be closed or opened. Install as follows. (See Figs. 1 and 2)

糸状部材７は、その一端を軸筒１内面の適当な位置に取り付け、そこから操作部４ａ上の動滑車５に掛け方向を反転し、次に前方ガイド８上に設けた固定滑車６に掛け再び方向を反転し、最後に芯材２の途中に設けた突起に残りの一端を取り付ける。ここでのそれぞれの位置の関係であるが、ペン先３が完全に格納された状態において、動滑車５と固定滑車６は可動範囲内で最も近くに位置し、糸状部材７の芯材２への取り付け部分は固定滑車６より最も離れた位置となるのが好ましい。なお図９では、実線がペン先格納時を、点線がペン先露出時の状態を表している。  One end of the thread-like member 7 is attached to an appropriate position on the inner surface of the shaft cylinder 1, and then the direction of the thread-like member 7 is reversed to the moving pulley 5 on the operation portion 4 a, and then hung on the fixed pulley 6 provided on the front guide 8. The direction is reversed again, and finally the remaining end is attached to the protrusion provided in the middle of the core member 2. The positional relationship here is that the moving pulley 5 and the fixed pulley 6 are located closest to each other in the movable range in a state where the pen tip 3 is completely retracted, and to the core material 2 of the thread-like member 7. It is preferable that the mounting portion is located farthest from the fixed pulley 6. In FIG. 9, the solid line represents the state when the pen tip is stored, and the dotted line represents the state when the pen tip is exposed.

なお、本筆記具未使用時（該ペン先を格納した状態）において、ペン先３が位置する前方ガイド８の軸孔は、蓋部材１０とシーリング９と芯材２によりほぼ密閉された空間となるため、ペン先３からのインクの蒸散を防ぐことが可能である。  When the writing instrument is not used (when the pen tip is stored), the shaft hole of the front guide 8 where the pen tip 3 is located is a substantially sealed space by the lid member 10, the sealing 9, and the core member 2. Therefore, it is possible to prevent the ink from evaporating from the nib 3.

インクカートリッジを用意したい場合は、該軸筒を分割可能な構造とし芯材後部１３にインクカートリッジ１６を脱着可能に設けるのもよい。  When an ink cartridge is desired, the shaft tube may be divided so that the ink cartridge 16 can be detachably attached to the core rear portion 13.

以上の構造により、本筆記具を使用する際は、図１４および図１５に示すように、持ち手人差し指にて操作部４ａを軸筒１後方に向けスライドさせると、動滑車５に掛けられた糸状部材７はその一端が軸筒１に固定されているので、動滑車５は後方に向け移動する際、回転しながら糸状部材７を後方に向け引っ張ることとなる。そして糸状部材７は固定滑車６により方向を反転しその先端に繋がれた芯材２を前方に向け引くこととなる。この時の移動距離を比較すると、芯材２の移動距離、すなわちペン先３の移動距離は、動滑車５の移動距離、すなわち操作部４ａの移動距離のほぼ２倍となる。  With the above structure, when the writing instrument is used, as shown in FIGS. 14 and 15, when the operation unit 4 a is slid toward the rear of the barrel 1 with the index finger of the handle, the thread-like shape hung on the movable pulley 5. Since one end of the member 7 is fixed to the shaft cylinder 1, when the movable pulley 5 moves rearward, the thread-like member 7 is pulled rearward while rotating. The direction of the thread-like member 7 is reversed by the fixed pulley 6 and the core material 2 connected to the tip thereof is pulled forward. Comparing the movement distance at this time, the movement distance of the core member 2, that is, the movement distance of the pen tip 3, is approximately twice the movement distance of the movable pulley 5, that is, the movement distance of the operation unit 4a.

一方、操作部４ａに取り付けられた蓋部材１０は後方に向け引っ張られるので、その先端部分は引き上げられて軸筒１先端の孔が開放され、ペン先３は軸筒１の先端より突出する。  On the other hand, since the lid member 10 attached to the operation unit 4a is pulled rearward, the tip portion thereof is pulled up to open the hole at the tip of the shaft tube 1, and the pen tip 3 protrudes from the tip of the shaft tube 1.

使用後は、操作部４ａを押さえていた指の力を抜くことで、コイルばね１２の作用により芯材２は後方に向け移動するが、その際、芯材２に取り付けられた糸状部材７は後方に向け引っ張られ、固定滑車６によって方向を反転し、動滑車５すなわち操作部４ａを前方へと移動させる。一方、ペン先３は前方ガイド８の軸孔に収まり、蓋部材１０は操作部４ａに押されて前方へと移動し前方ガイド８の軸孔の先端を塞ぐ位置へと収まる。  After use, the core member 2 is moved backward by the action of the coil spring 12 by removing the force of the finger holding the operation portion 4a. At that time, the thread-like member 7 attached to the core member 2 is Pulled rearward, the direction is reversed by the fixed pulley 6, and the movable pulley 5, that is, the operation portion 4a is moved forward. On the other hand, the pen tip 3 is accommodated in the shaft hole of the front guide 8, and the lid member 10 is pushed by the operation portion 4 a and moves forward to be in a position where the tip of the shaft hole of the front guide 8 is closed.

また、例えば蛍光ペンの場合、そのペン先は先端が斜めにカットされているため、横方向に筆記する場合と縦方向に筆記する場合とでは上下の向きを変える必要がある。しかし本実施例のように、筆記具を持ち替えることなく操作部を持ち手の人差し指等により操作する筆記具の場合、軸筒ごと回動させたのでは操作部が邪魔な位置に来てしまう。そこで本発明では軸筒内部においてその調整が行える構造を考案したもので、実施例としては、前述のとおり設置した角度固定具１４を軸筒１円周方向に９０度スライドさせることにより芯材後部１３からペン先３にかけ一体となって回動し、その結果ペン先３の上下の向きが変わるといった構造が挙げられる。（図７、図８参照）これにより、本筆記具使用者は、縦書きの書籍に用いる場合と横書きの書籍に用いる場合、それぞれに応じてペン先の向きを設定し直して使用することが可能となる。  For example, in the case of a fluorescent pen, since the tip of the pen tip is cut obliquely, it is necessary to change the vertical direction between writing in the horizontal direction and writing in the vertical direction. However, in the case of a writing instrument in which the operation unit is operated with the index finger or the like of the holding hand without changing the writing instrument as in the present embodiment, the operation unit comes to a hindrance position when the shaft cylinder is rotated. Therefore, in the present invention, a structure capable of adjusting the inside of the shaft cylinder has been devised. As an embodiment, the angle fixing tool 14 installed as described above is slid 90 degrees in the circumferential direction of the shaft cylinder 1 so that the rear part of the core For example, a structure in which the pen 13 is rotated integrally from 13 to the pen tip 3, and as a result, the vertical direction of the pen tip 3 is changed. (Refer to FIG. 7 and FIG. 8) This allows the writing instrument user to set the pen tip direction accordingly and use it for vertical writing and horizontal writing. It becomes.

なお、この場合縦書きにおいては、右利きの者と左利きの者とではペン先の向きが反対となる。その対応策としては、芯材後部１３において角度固定用溝１５から円周方向に９０度ずらした位置に角度固定用溝をもう一つ別に設け、角度固定具１４を軸筒に対し脱着自在とし、右利きと左利きそれぞれに適した側の溝に、角度固定具１４の内側の突起が収まるよう軸筒上に嵌めて使用する方法、または、ペン先を芯材より抜き差し自在なものとし、ペン先のみを芯材に差し直すことで調整する方法などが挙げられる。  In this case, in vertical writing, the direction of the pen tip is opposite between the right-handed person and the left-handed person. As a countermeasure, another angle fixing groove is provided at a position shifted 90 degrees in the circumferential direction from the angle fixing groove 15 in the core rear portion 13 so that the angle fixing tool 14 can be freely attached to and detached from the shaft tube. , A method of fitting on the shaft cylinder so that the protrusion on the inside of the angle fixing tool 14 fits in the groove on the side suitable for each of right-handed and left-handed, or the pen tip can be inserted and removed from the core, and the pen For example, a method of adjusting by re-inserting only the tip into the core may be used.

また、軸筒１より露出したペン先３が、操作部を押さえている指の力を抜いても軸筒１内に戻らなくするため、または、不用意なペン先の突出を防止するため、操作部の構造を変え軸筒上にストッパーを設けるのもよい。  In addition, in order to prevent the pen tip 3 exposed from the shaft tube 1 from returning into the shaft tube 1 even if the finger force holding the operation unit is removed, or to prevent an inadvertent protrusion of the pen tip, It is also possible to change the structure of the operation portion and provide a stopper on the shaft cylinder.

実施例としては、まずベースとなる操作部４ｂに対し、爪２０を有するクリップ１９を回動軸２１により軸着し、板ばね２２を用いて、クリップ１９先端が軸筒１の表面に向かって押しつけられる構造とする。（図１０参照）  As an embodiment, first, a clip 19 having a claw 20 is attached to a base operation portion 4 b by a rotating shaft 21, and a tip of the clip 19 is directed toward the surface of the shaft tube 1 by using a leaf spring 22. The structure is to be pressed. (See Figure 10)

この構造により、軸筒１上の図１０に示す位置にストッパー２３を設けた場合、力を加えない限りは爪２０がストッパー２３に引っかかった状態となるので、操作部は軸筒後方に向けてのスライドができないこととなる。つまり不用意なペン先の突出を避けることが可能となる。  With this structure, when the stopper 23 is provided at the position shown in FIG. 10 on the shaft cylinder 1, the claw 20 is caught by the stopper 23 unless a force is applied. It will be impossible to slide. That is, inadvertent pen tip protrusion can be avoided.

また、図１１に示すように、その位置と形をストッパー２４のようにすれば、ペン先の露出状態を器械的に維持することが可能となる。  Also, as shown in FIG. 11, if the position and shape of the stopper 24 are used, the exposed state of the pen tip can be maintained mechanically.

また、前記の二つの効果を両立するため、図１２に示すように、その形状をストッパー２５のようにしてもよい。  Further, in order to achieve both of the above two effects, the shape may be a stopper 25 as shown in FIG.

また、ペン先の露出状態を維持する方法としては、操作部の形状を図１３に示すような単純なものとし、クリップ部分に弾性素材を用いて、爪２７を跨がせてストッパー２６に引っ掛けるのもよい。なお図１３ではＡがペン先格納時、Ｂが操作部を指で押さえての筆記時、Ｃが操作部を器械的に系止しての筆記時におけるそれぞれの位置関係を示したものである。  Further, as a method for maintaining the exposed state of the pen tip, the shape of the operation unit is as simple as shown in FIG. 13, and an elastic material is used for the clip portion, and the nail 27 is straddled and hooked on the stopper 26. It's also good. FIG. 13 shows the positional relationship between A when the pen is retracted, B when writing with the operation part pressed with a finger, and C when writing with the operation part mechanically stopped. .
