Description

【0001】
【発明の属する技術分野】
本発明は、ノック部材をノック操作することによりボ−ルペン等のリフィ−ルを軸筒から繰り出すようにしたノック式筆記具に関するものである。
【0002】
【従来の技術】
ボ−ルペン等のリフィ−ルをノック操作で繰り出す機構として、例えば軸筒内に回転カム機構を設けたり、軸筒に窓孔を開口しこの窓孔を通る突起をクリップ爪若しくはノック部材に形成しノック部材若しくはクリップ爪に該突起と係合するカム部を形成した機構が知られている。上記クリップとノック部材を利用する構成は、構成が複雑であり、その上軸筒に窓孔を設けて突起を挿通させているので、ポケット等にクリップで挟み込む場合に、支障があり、また軸筒の強度も弱くなるおそれもあった。
【0003】
特公平4−26319号公報には、軸筒に突起を挿通させるための窓孔を形成せずにクリップの基端部の懐部の裏面側にノックガイド手段を形成し、このノックガイド手段に係合するノックガイド用の突子を芯パイプに固定したダブルノック式の筆記具が記載されている。この筆記具は、軸筒に窓孔を形成しないので、上述したごとき問題を生じないが、芯パイプに直接突子を取り付けなければならないので、ボ−ルペンのリフィ−ルのようにリフィ−ル交換式の筆記具には使用することができない。また、上記突子はドライブリングに形成され、このドライブリングを芯タンクに遊嵌するため芯パイプに2つの圧入リングを圧入してドライブリングの軸方向の移動を規制しなければならないので、構成が複雑で部品点数も多く、経済的に得られない。
【0004】
【発明が解決しようとする課題】
本発明の解決課題は、回転カム機構を用いないノック式筆記具において、軸筒に係合用の突起を挿通させるための窓孔を形成せずに、少ない部品点数で、かつ構成が簡単なノック式筆記具を提供することである。
【0005】
【課題を解決するための手段】
本発明によれば、軸筒内にリフィ−ルを収納し該リフィ−ルを後方に付勢し軸筒の後部に設けたノック部材をノックして上記リフィ−ルを前進しその先端を軸筒から突出させるようにしたノック式筆記具において、上記ノック部材は上記軸筒に回り止めされて軸方向に移動可能に挿入され係止縁と軸方向に延びるア−ムと該ア−ムの先端に形成した突起を有し、一方上記軸筒内に突出する取付部を有するクリップを形成し、該取付部の内面にノック部材の上記突起に係合するカム部を設け、該カム部は上記ノック部材をノックした際上記ア−ムを周方向にたわませて上記突起を周方向に変位させる周方向傾斜面と上記リフィ−ルの先端が軸筒から突出したとき上記突起の後退を案内する係合案内面と該ノック部材の後退を阻止するよう上記突起に係合するストップ面と上記ノック部材をノックして該ストップ面により前方に上記突起を前進させた際上記ア−ムを軸筒の内方にたわませて上記ストップ面を越えて上記突起が後退できるようにした後退案内面を具備し、上記ノック部材が後退する際クリップの上記取付部の前端にノック部材の上記係止縁が当接するよう上記クリップを上記軸筒に取り付けたことを特徴とするノック式筆記具が提供され、上記課題が解決される。
【0006】
【発明の実施の形態】
図1等は本発明の一実施例を示し、口金(2)を先端に有する軸筒(1)内には、ボ−ルペン、水性ボ−ルペン等のリフィ−ル(3)が収納され、ばね(4)で該リフィ−ル(3)は後方に付勢されており、後記するように軸筒(1)の後部に挿入したノック部材(5)をノックして上記リフィ−ルを前進しその先端を軸筒(1)から突出させて筆記する。
【0007】
上記ノック部材(5)は、図1,図6に示すようにリブ(6)を有し、該リブ(6)を軸筒(1)に形成した案内溝(7)に係合させることにより軸方向に移動可能に回り止めされているが、該ノック部材の外形及び軸筒の内形を異形状に形成することにより軸方向に移動可能に回り止めすることもできる。
【0008】
また、該ノック部材(5)は、軸筒から突出するノック部(8)を後端に有し、前端には上記リフィ−ル(3)の後端を挿入保持する保持部(9)を有している。該保持部(9)の後方には抜け止めのための係止縁(10)が形成され、該係止縁(10)と上記ノック部(8)の間には凹部(11)が設けられている。上記保持部(9)からノック部(8)に向かって上記凹部(11)内で軸方向に延びるようア−ム(12)を形成し、該ア−ム(12)の先端には突起(13)を形成してある。上記ノック部材はプラスチック材料で一体成形されているので、該ア−ム(12)は軸筒の周方向及び内外方向にたわんで揺動し、軸方向位置に復帰することができる。
【0009】
上記軸筒(1)にはクリップ(14)が取り付けられている。該クリップ(14)は、公知のように取付部(15)を軸筒(1)の取付孔(16)に挿入して固着され、該取付部(15)の内面は上記軸筒(1)内に突出している。該取付部(15)の取付構造は種々に構成することができるが、図1においては、実公平4−13200号公報等に記載されているように上記取付孔(16)を角孔に形成し、該角孔に内接するように取付部(15)の外形を形成し、該取付部(15)の前端に形成した係止爪(17)を軸筒(1)の内側に挿入して取付孔の縁に係合し、該取付部(15)の後端を取付孔(16)内に押し込んで軸筒に取り付けてある。
【0010】
上記クリップ(14)の取付部(15)の内面には、上記ノック部材(5)の突起(13)に係合するカム部(18)が一体的に形成されている。該カム部(18)は、図7,図8に示すように上記ノック部材(5)をノックした際上記突起(13)を周方向に変位させる周方向傾斜面(19)と、上記リフィ−ル(3)の先端が軸筒(1)から突出したとき上記周方向傾斜面(19)を越えてきた突起(13)の後退を阻止するよう該突起(13)に係合するストップ面(20)と、上記ストップ面へ向う突起(13)の後退を案内する係合案内面(21)と、該ストップ面(20)より前方に上記突起(13)が前進したとき上記ストップ面(20)を越えて上記突起(13)が後退できるよう斜面(22)を介して該突起(13)を内方へ移動させる上記ストップ面と同じ高さの後退案内面(23)を具備し、上記係合案内面(21)は、後退案内面(23)の側面に形成されている。上記周方向傾斜面(19)、ストップ面(20)、係合案内面(21)、斜面(22)を有する後退案内面(23)等は、図8においては取付部(15)の一側に沿って設けてあるが、適宜の位置に分散して設けたり、その他の適宜のガイド面等を設けたりしてもよい。
【0011】
上記カム部(18)により上記突起(13)が周方向や内方に移動する際、該突起(13)は揺動可能な上記ア−ム(12)の先端に設けられているので、該ア−ム(12)が周方向や内方にたわむことにより上記カム部に追従することができる。
【0012】
上記ノック部材(5)とクリップ(14)を軸筒(1)に組み込むには、先ずノック部材(5)を上記リブ(6)が案内溝(7)に一致するように軸筒(1)の後端から軸筒内に挿入し、その後上記取付部(15)の前端の係止爪(17)にノック部材(5)の上記係止縁(10)が当接するように上記クリップ(14)を軸筒(1)に取り付ければよい。
【0013】
而して、図1(A),(B)に示すように、リフィ−ル(3)が軸筒(1)内に没入している状態では、上記ばね(4)の作用により上記ノック部材(5)は、係止縁(10)が取付部(15)の前端に当接して抜け止めされており、上記ア−ム(12)に設けた突起(13)はカム部(18)から外れている。
【0014】
そして、ノック部材(5)をノックすると、図2(A),(B)に示すように、上記突起(13)は上記カム部の周方向傾斜面(19)に案内されて周方向に変化する。このとき、上記ア−ム(12)は、該ノック部材(5)が回り止めされているから、図2(B)のように周方向にたわむ。
【0015】
上記周方向傾斜面(19)の先端を越えると、図3(A),(B)に示すように上記ア−ム(12)は復元力により少し周方向に戻り、上記突起は後退案内面(23)の側面に形成した係合案内面(21)に当り、リフィ−ル(3)の先端は軸筒の先端から突出する。
【0016】
その後、ノック部材(5)のノックを止めると、上記ばね(4)の作用で上記リフィ−ル(3)及びノック部材(5)は少し後退し、上記突起(13)はストップ面(20)に係合し、上記ノック部材(5)の後退は阻止される(図4(A),(B))。この状態でリフィ−ルは軸筒から突出しているので、筆記することができる。
【0017】
さらに、図5(A),(B)に示すように上記ノック部材(5)をノックすると、上記突起(13)は上記斜面(22)を介して後退案内面(23)により前進しながら内方に変位し、このときア−ム(12)は内方にたわむ。この状態でノックを止めると、上記突起(13)は上記ストップ面(20)を越えて後退し、該カム部を越えたとき上記ア−ム(12)はもとの状態に復帰し、図1に示す状態に戻る。
【0018】
【発明の効果】
本発明は上記のように構成されているので、従来のようにカム部と係合する突起を挿通させるための窓孔を軸筒に設ける必要がなく、クリップを用いてポケットに支持する際に何ら支障ないようにでき、軸筒も丈夫であり、またクリップの取付部とノック部材でカム機構を構成したから、リフィ−ルには特別の部材を設けなくてもよく、通常のボ−ルペン、水性ボ−ルペン等のリフィ−ルを使用することができ、部品点数も少なく、経済的に得ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a knock-type writing instrument in which a refill such as a ball-point pen is fed out from a shaft tube by knocking a knock member.
[0002]
[Prior art]
As a mechanism for feeding a refill such as a ballpoint pen by knocking operation, for example, a rotating cam mechanism is provided in the shaft tube, a window hole is opened in the shaft tube, and a protrusion passing through the window hole is formed on the clip claw or knock member A mechanism is known in which a cam portion that engages with the protrusion is formed on the knock member or clip claw. The structure using the clip and the knock member is complicated, and the upper shaft cylinder is provided with a window hole and a projection is inserted therethrough, so there is a problem when the clip is inserted into a pocket or the like. There was also a possibility that the strength of the tube might be weakened.
[0003]
In Japanese Patent Publication No. 4-26319, a knock guide means is formed on the back side of the pocket of the base end portion of the clip without forming a window hole for inserting the protrusion into the shaft tube. A double-knock type writing instrument in which an engaging knock guide protrusion is fixed to a core pipe is described. Since this writing instrument does not form a window hole in the shaft tube, it does not cause the above-mentioned problem. However, since a protrusion must be directly attached to the core pipe, it is necessary to replace the refill like a ball pen refill. Cannot be used for formula writing instruments. Further, the protrusion is formed in the drive ring, and in order to loosely fit the drive ring into the core tank, it is necessary to press the two press-fit rings into the core pipe to restrict the axial movement of the drive ring. However, it is complicated and has a large number of parts, which is not economical.
[0004]
[Problems to be solved by the invention]
The problem to be solved by the present invention is that a knock type writing instrument that does not use a rotating cam mechanism has a small number of parts and a simple configuration without forming a window hole for inserting an engaging projection into the shaft cylinder. It is to provide a writing instrument.
[0005]
[Means for Solving the Problems]
According to the present invention, the refill is accommodated in the shaft tube, the refill is urged rearward, the knock member provided at the rear portion of the shaft tube is knocked, and the refill is advanced to move the tip of the shaft to the shaft. In the knock-type writing instrument projected from the cylinder, the knock member is fixed to the shaft cylinder and is inserted so as to be movable in the axial direction, an arm extending in the axial direction, an arm extending in the axial direction, and a tip of the arm A clip having an attachment portion protruding into the shaft cylinder, and a cam portion engaging with the protrusion of the knock member is provided on the inner surface of the attachment portion. When the knock member is knocked, the arm is deflected in the circumferential direction to guide the retraction of the projection when the circumferentially inclined surface that displaces the projection in the circumferential direction and the tip of the refill project from the shaft cylinder. The protrusion and the engagement guide surface to prevent the knock member from retreating. When the projection is advanced forward by the stop surface by knocking the stop surface engaged with the knock member and the knock member, the arm is deflected inward of the shaft cylinder and the projection exceeds the stop surface. The clip is attached to the shaft cylinder so that the locking edge of the knock member comes into contact with the front end of the attachment portion of the clip when the knock member is retracted. A characteristic knock type writing instrument is provided to solve the above-mentioned problems.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an embodiment of the present invention, and a refill (3) such as a ballpoint pen or an aqueous ballpoint pen is accommodated in a shaft cylinder (1) having a base (2) at its tip. The refill (3) is urged rearward by the spring (4). As will be described later, the knock member (5) inserted in the rear portion of the shaft tube (1) is knocked to advance the refill. The tip is projected from the shaft tube (1) and written.
[0007]
The knock member (5) has a rib (6) as shown in FIGS. 1 and 6, and the rib (6) is engaged with a guide groove (7) formed in the shaft tube (1). Although it is prevented from rotating in the axial direction, it can also be prevented from rotating in the axial direction by forming the outer shape of the knock member and the inner shape of the shaft tube differently.
[0008]
The knock member (5) has a knock portion (8) protruding from the shaft tube at the rear end, and a holding portion (9) for inserting and holding the rear end of the refill (3) at the front end. Have. A retaining edge (10) is formed behind the holding portion (9) to prevent the retaining portion (9), and a recess (11) is provided between the retaining edge (10) and the knock portion (8). ing. An arm (12) is formed so as to extend in the axial direction in the recess (11) from the holding portion (9) toward the knock portion (8), and a protrusion ( 13) is formed. Since the knock member is integrally formed of a plastic material, the arm (12) can bend and swing in the circumferential direction and inward / outward direction of the shaft cylinder and return to the axial position.
[0009]
A clip (14) is attached to the shaft cylinder (1). As is well known, the clip (14) is fixed by inserting the mounting portion (15) into the mounting hole (16) of the shaft tube (1), and the inner surface of the mounting portion (15) is fixed to the shaft tube (1). Protrusively inside. The mounting structure of the mounting portion (15) can be variously configured. In FIG. 1, the mounting hole (16) is formed as a square hole as described in Japanese Utility Model Publication No. 4-13200. Then, the outer shape of the attachment portion (15) is formed so as to be inscribed in the square hole, and the locking claw (17) formed at the front end of the attachment portion (15) is inserted inside the shaft tube (1). It is engaged with the edge of the mounting hole, and the rear end of the mounting portion (15) is pushed into the mounting hole (16) to be mounted on the shaft tube.
[0010]
A cam portion (18) that engages with the protrusion (13) of the knock member (5) is integrally formed on the inner surface of the attachment portion (15) of the clip (14). The cam portion (18) includes a circumferentially inclined surface (19) for displacing the protrusion (13) in the circumferential direction when the knock member (5) is knocked as shown in FIGS. Stop surface (3) that engages the protrusion (13) to prevent the protrusion (13) that has passed the circumferential inclined surface (19) from retreating when the tip of the rod (3) protrudes from the barrel (1). 20), an engagement guide surface (21) for guiding the retraction of the protrusion (13) toward the stop surface, and the stop surface (20) when the protrusion (13) advances forward from the stop surface (20). ), And a protrusion guide surface (23) having the same height as the stop surface for moving the protrusion (13) inward through the inclined surface (22) so that the protrusion (13) can move backward. The engagement guide surface (21) is formed on the side surface of the reverse guide surface (23). The circumferentially inclined surface (19), the stop surface (20), the engagement guide surface (21), the reverse guide surface (23) having the inclined surface (22), etc. are one side of the mounting portion (15) in FIG. However, it may be distributed at appropriate positions, or other appropriate guide surfaces may be provided.
[0011]
When the projection (13) is moved in the circumferential direction or inward by the cam portion (18), the projection (13) is provided at the tip of the swingable arm (12). The arm (12) can follow the cam portion by bending in the circumferential direction or inward.
[0012]
In order to incorporate the knock member (5) and the clip (14) into the shaft tube (1), first, the knock member (5) is inserted into the shaft tube (1) so that the rib (6) is aligned with the guide groove (7). The clip (14) is inserted into the shaft cylinder from the rear end, and then the locking edge (10) of the knock member (5) is in contact with the locking claw (17) at the front end of the mounting portion (15). ) May be attached to the shaft cylinder (1).
[0013]
Thus, as shown in FIGS. 1A and 1B, when the refill (3) is immersed in the shaft cylinder (1), the knock member is acted on by the action of the spring (4). In (5), the locking edge (10) abuts against the front end of the mounting portion (15) and is prevented from coming off, and the projection (13) provided on the arm (12) is separated from the cam portion (18). It is off.
[0014]
When the knock member (5) is knocked, as shown in FIGS. 2 (A) and 2 (B), the protrusion (13) is guided by the circumferential inclined surface (19) of the cam portion and changes in the circumferential direction. To do. At this time, the arm (12) bends in the circumferential direction as shown in FIG. 2 (B) because the knock member (5) is prevented from rotating.
[0015]
When the tip of the circumferentially inclined surface (19) is passed, the arm (12) returns slightly in the circumferential direction by the restoring force as shown in FIGS. The tip of the refill (3) protrudes from the tip of the shaft tube when it hits the engagement guide surface (21) formed on the side surface of (23).
[0016]
Thereafter, when the knocking of the knocking member (5) is stopped, the refill (3) and the knocking member (5) are slightly retracted by the action of the spring (4), and the protrusion (13) is moved to the stop surface (20). The knock member (5) is prevented from retreating (FIGS. 4A and 4B). In this state, the refill protrudes from the shaft tube and can be written.
[0017]
Further, as shown in FIGS. 5A and 5B, when the knock member (5) is knocked, the protrusion (13) moves forward through the inclined surface (22) by the retraction guide surface (23). The arm (12) bends inward at this time. When the knocking is stopped in this state, the protrusion (13) moves backward beyond the stop surface (20), and when the cam part is exceeded, the arm (12) returns to the original state. Return to the state shown in FIG.
[0018]
【The invention's effect】
Since the present invention is configured as described above, it is not necessary to provide a window hole in the shaft tube for inserting a projection that engages with the cam portion as in the prior art, and when supporting a pocket using a clip. Since it can be prevented from any trouble, the shaft tube is strong, and the cam mechanism is constituted by the clip mounting portion and the knock member. Therefore, it is not necessary to provide a special member for the refill. Further, a refill such as an aqueous ball-point pen can be used, and the number of parts is small, so that it can be obtained economically.
