Description

本発明は、軸筒内に、複数の筆記体を配設してなるスライド式の多芯筆記具に関する。   The present invention relates to a slide-type multi-core writing instrument in which a plurality of writing bodies are arranged in a shaft cylinder.

従来から、特開２００１−２３９７９１号公報「スライド式の多芯筆記具」に開示しているように、軸筒内に、複数の筆記体を配設し、各筆記体の後端に、コイルスプリングにより軸筒後端方向に付勢して配設したスライド部材を、各スライド部材に形成した***部が、軸筒後端部に形成した窓部より突出した状態で摺動自在に収納し、一方の***部を軸筒先端方向にスライドせしめることで、一方のスライド部材に形成した係止部が、軸筒後端部内に形成した被係止部に係止することで、一方の筆記体の先端部を軸筒先端開口部より突出し、他方の***部を軸筒先端方向にスライドせしめることで、他方のスライド部材に形成した解除突起が、一方のスライド部材に当接し、被係止部に係止していた一方の係止部の係止を解除し、さらに他方の***部を軸筒先端方向にスライドせしめ、他方の係止部を軸筒後端部に形成した他方の被係止部に係止することで、他方の筆記体の先端部を軸筒先端開口部より突出可能なスライド式の多芯筆記具はよく知られている。   Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 2001-239791 “Slide-type multi-core writing instrument”, a plurality of writing bodies are arranged in a shaft cylinder, and a coil spring is provided at the rear end of each writing body. Slidably accommodates the slide members arranged to be urged in the direction of the rear end of the shaft tube, with the raised portions formed on each slide member protruding from the window formed on the rear end portion of the shaft tube, By sliding one raised portion in the direction of the tip of the shaft tube, the locking portion formed on one slide member is locked to the locked portion formed in the rear end of the shaft tube, so that one of the writing bodies The release protrusion formed on the other slide member comes into contact with one slide member by projecting the tip end portion of the shaft tube from the opening portion of the shaft tube tip end and sliding the other raised portion toward the tip end of the shaft tube. Unlock one locking part that was locked to the other, and The tip of the other cursive body is moved to the tip of the shaft cylinder by sliding the raised portion of the shaft toward the tip of the shaft cylinder and locking the other locking portion to the other locked portion formed at the rear end of the shaft cylinder. A slide-type multi-core writing instrument that can protrude from the opening is well known.

また、特開２００１−２３９７９１号公報「スライド式の多芯筆記具」に図示してあるように、従来のスライド式の多芯筆記具において、スライド部材の***部の形状は、指に当接し易く、且つ安全性を考慮して、縦断面を略円弧形状としてある。   In addition, as illustrated in Japanese Patent Application Laid-Open No. 2001-239791 “Slide-type multi-core writing instrument”, in the conventional slide-type multi-core writing instrument, the shape of the raised portion of the slide member is easy to come into contact with the finger, In consideration of safety, the longitudinal section has a substantially arc shape.

ところで、スライド式の多芯筆記具は、***部に指を当接してスライドさせるため、操作性を高めるには、***部の高さを高くして***部の窓部からの突出量を多くする、或いは幅を厚くすることによって、***部が指に当接し易くすることが好ましい。   By the way, since the slide-type multi-core writing instrument slides with a finger in contact with the raised portion, in order to improve operability, the height of the raised portion is increased to increase the protruding amount of the raised portion from the window portion. Alternatively, it is preferable to increase the width so that the raised portion easily comes into contact with the finger.

また、特開平８−１８７９８９号「ノック式筆記具のノック部材」に、***部の頂面に幅方向に向かって延びる凹部を形成し、***部を軸筒先端方向にスライドするときに、指が滑り難くなるための滑り止め部を有するスライド部材が図示されている。
「特開２００１−２３９７９１号公報」 「特開平８−１８７９８９号公報」 In addition, a recess extending in the width direction is formed on the top surface of the raised portion in Japanese Patent Laid-Open No. Hei 8-18789 “Knock member of the knock type writing instrument”, and when the raised portion is slid in the distal end of the shaft tube, A slide member having a non-slip portion for preventing slipping is shown.
"JP 2001-239791 A" "Japanese Patent Laid-Open No. 8-18789"

しかし、***部の高さを高く、或いは幅を厚くすると、***部の体積が多くなり、成形時の圧力差や固化する冷却時間差によって、***部にヒケや歪が発生し易いことも事実である。   However, if the height of the raised portion is increased or the width is increased, the volume of the raised portion increases, and it is also true that sinks and distortions are likely to occur in the raised portion due to pressure differences during molding and cooling time differences during solidification. is there.

また、特許文献２のスライド部材を操作するには、軸筒の軸心に対して指を平行に位置させ、軸心方向への押圧しながら軸筒先端方向へのスライドする力が必要であるのに対し、特許文献１のスライド部材は、***部の後端側に指を当接し、斜め方向又は軸筒後端方向から押圧力を加えればスライド部材を軸筒先端開口部方向へスライドできるため、軸心方向への押圧力を必要せず操作性がよい。   Further, in order to operate the slide member of Patent Document 2, it is necessary to place a finger parallel to the shaft center of the shaft tube and to slide the shaft tube toward the tip of the shaft tube while pressing in the shaft center direction. On the other hand, the slide member disclosed in Patent Document 1 can slide the slide member toward the axial tube tip opening portion by applying a pressing force from the oblique direction or the axial tube rear end direction with the finger in contact with the rear end side of the raised portion. Therefore, it does not require a pressing force in the axial direction, and operability is good.

更にまた、軸筒は一般的に円筒体であるため、***部を操作する時に、回転方向への力が加わり、***部から指が外れてしまうことがあるため、軸筒を強く把持しながら***部を操作する必要があった。   Furthermore, since the shaft tube is generally a cylindrical body, when operating the raised portion, a force in the rotational direction is applied and the finger may come off from the raised portion. It was necessary to manipulate the ridge.

本発明の目的は、スライド部材の***部を軸筒先端方向にスライドし易く、且つ***部にヒケや歪みが発生し難いスライド式の多芯筆記具を提供することにある。   An object of the present invention is to provide a slide-type multi-core writing instrument in which a raised portion of a slide member can be easily slid in the axial tube tip direction, and the raised portion is less prone to sink or distortion.

本発明は前記目的を達成するために、軸筒内に、複数の筆記体をコイルスプリングにより軸筒後端方向に付勢し配設し、各筆記体の後端に装着したスライド部材の***部が、軸筒後端部に一体または付設部材に形成した窓部より外方に突出した状態で摺動自在に収納し、前記***部を軸筒先端方向にスライドすることによって、前記筆記体の筆記先端部を軸筒先端開口部より出没可能なスライド式の多芯筆記具において、前記スライド部材の***部が、縦断面を略円弧形状とするとともに、少なくとも前記***部の頂面に、軸筒先端方向に向かって延びる凹部を形成したことを特徴とする。   In order to achieve the above-mentioned object, the present invention achieves the above-mentioned object by providing a plurality of writing bodies in the shaft cylinder by urging them in the direction of the rear end of the shaft cylinder by means of coil springs, and raising the slide members attached to the rear ends of the respective writing bodies. The part is slidably accommodated in a state of projecting outward from a window part formed integrally with the rear end part of the shaft cylinder or in the attached member, and the raised part is slid in the tip end direction of the shaft cylinder, thereby In the slide-type multi-core writing instrument capable of projecting and retracting the writing tip portion from the shaft tube tip opening portion, the raised portion of the slide member has a substantially arc shape in the longitudinal section, and at least on the top surface of the raised portion. A concave portion extending in the tube tip direction is formed.

また、前記***部の凹部の壁面が、略円弧形状であることを特徴とする。   Moreover, the wall surface of the recessed part of the said protruding part is substantially arc shape, It is characterized by the above-mentioned.

本発明は、スライド部材の***部を軸筒先端方向にスライドし易く、且つ***部にヒケや歪みが発生し難いスライド式の多芯筆記具を提供することができた。   The present invention can provide a slide-type multi-core writing instrument in which the raised portion of the slide member can be easily slid in the axial tube tip direction and the raised portion is less prone to sink and distortion.

本発明の実施例を、図面を用いて説明する。同部材、同箇所を示すものに対しては、同符号を付してある。   Embodiments of the present invention will be described with reference to the drawings. The same reference numerals are given to the same members and parts indicating the same portions.

本発明のスライド式の多芯筆記具１は、前軸２の後端部に後軸３を螺着し、この後軸３の後端に弾発部材１３により後方に付勢して摺動可能に摺動体４を配設し、前軸２、後軸３および摺動体４内に、ボールペンＡとシャープペンシルＢを、コイルスプリング１４、１５により後方に付勢させ収納している。   The slide-type multi-core writing instrument 1 of the present invention is slidable by a rear shaft 3 screwed to the rear end portion of the front shaft 2 and urged rearward by a resilient member 13 to the rear end of the rear shaft 3. The sliding body 4 is disposed on the front shaft 2, the rear shaft 3, and the sliding body 4, and the ballpoint pen A and the mechanical pencil B are urged rearward by the coil springs 14 and 15 and stored therein.

ボールペンＡは、インキ収容筒６の先端に、ボール８を回転自在に抱持したチップ部材７を圧入装着してある。シャープペンシルＢは、鉛芯ケース９に先端パイプ１０を嵌着してある。また、インキ収容筒６および鉛芯ケース１０の後端開口部には、操作体となるスライド部材１１、１２の先端部を圧入装着し、***部１１ａ、１２ａが、摺動体４に形成した窓部４ａから軸筒の外周面より突出するように保持してある。また、摺動体４の後端部には頭冠５を装着してある。   In the ballpoint pen A, a tip member 7 holding a ball 8 rotatably is press-fitted and attached to the tip of the ink containing cylinder 6. The mechanical pencil B has a tip pipe 10 fitted to a lead core case 9. Further, the front end portions of the slide members 11 and 12 serving as operating bodies are press-fitted into the rear end openings of the ink containing cylinder 6 and the lead core case 10, and the raised portions 11 a and 12 a are windows formed on the slide body 4. It is held so as to protrude from the outer peripheral surface of the shaft tube from the portion 4a. A crown 5 is attached to the rear end of the sliding body 4.

シャープペンシルＢを使用する際には、前軸２又は後軸３を把持し、***部６の後端側に指を当接し、***部１２ａを前軸２の先端開口部２ａ方向にスライドせしめることで、スライド部材１２の係止部１２ｂが摺動体４に形成した被被子部４ｂに係止することにより、シャープペンシルＢの先端パイプ１０を前軸２の先端開口部２ａから突出させ、摺動体４を前軸２の先端開口部２ａ方向に押圧して鉛芯を繰り出して使用する。   When the mechanical pencil B is used, the front shaft 2 or the rear shaft 3 is gripped, a finger is brought into contact with the rear end side of the raised portion 6, and the raised portion 12 a is slid in the direction of the distal end opening 2 a of the front shaft 2. As a result, the locking portion 12b of the slide member 12 is locked to the to-be-covered portion 4b formed on the sliding body 4, thereby causing the tip pipe 10 of the mechanical pencil B to protrude from the tip opening 2a of the front shaft 2 and sliding. The moving body 4 is pressed in the direction of the front end opening 2a of the front shaft 2 to feed out the lead core for use.

シャープペンシルＢの先端パイプ１０を前軸２の先端開口部２ａから突出した状態から、ボールペンＡを使用する際には、前軸２又は後軸３を把持し、***部１１の後端側に指を当接し、***部１１ａを前軸２の先端開口部２ａ方向にスライドせしめることで、スライド部材１１の解除突起１１ｃが、被係止部に係止しているスライド部材１２の玉部１２ｄに当接し、係止部１２ｂを押し出し、スライド部材１２の係止を解除させると、スライド部材１２は、コイルスプリング１５の弾発力によって元の状態に戻る。さらに***部１１ａを前軸先端開口部２ａ方向に押圧せしめることで、スライド部材１１の係止部１１ｂが被係止部４ｂに係止して、ボールペンＡのチップ部材７を突出させて使用することができる。   When using the ballpoint pen A from the state where the tip pipe 10 of the mechanical pencil B protrudes from the tip opening 2 a of the front shaft 2, the front shaft 2 or the rear shaft 3 is gripped and the rear end side of the raised portion 11 is The release protrusion 11c of the slide member 11 is locked to the locked portion by the ball 12d of the slide member 12 by abutting the finger and sliding the raised portion 11a in the direction of the tip opening 2a of the front shaft 2. When the locking portion 12b is pushed out and the locking of the slide member 12 is released, the slide member 12 returns to the original state by the elastic force of the coil spring 15. Further, by pressing the raised portion 11a in the direction of the front shaft tip opening 2a, the locking portion 11b of the slide member 11 is locked to the locked portion 4b, and the tip member 7 of the ballpoint pen A is projected and used. be able to.

各スライド部材１１、１２の***部１１ａ、１２ａは、縦断面形状を円弧形状としてあるので、***部１１ａ、１２ａの後端側に指が当接し易く、且つ安全な形状であり、***部１１ａ、１２ａを指で操作する時に、***部１１ａ、１２ａの後端側に当接し押圧力を加え（矢印Ａ方向）ながら、前軸２の先端開口部２ａ方向に押圧（矢印Ｂ方向）させることによりスライド部材１１、１２を前軸２の先端開口部２ａ方向にスライドせしめ、ボールペンＡ及びシャープペンシルＢを容易に出没可能であるため、軸心Ｊ方向への（矢印Ｃ方向）への押圧力を加えながら押圧しなくてもスライド操作することができる。   Since the raised portions 11a and 12a of the slide members 11 and 12 have an arc shape in the longitudinal section, the fingers can easily come into contact with the rear ends of the raised portions 11a and 12a, and the raised portions 11a and 12a have a safe shape. When the finger 12a is operated with a finger, it is pressed (in the direction of arrow B) in the direction of the tip opening 2a of the front shaft 2 while abutting and applying pressure (in the direction of arrow A) to the rear end side of the raised portions 11a, 12a. The slide members 11 and 12 are slid in the direction of the front end opening 2a of the front shaft 2 and the ballpoint pen A and the mechanical pencil B can be easily moved in and out, so that the pressing force in the direction of the axis J (arrow C direction) It is possible to perform a slide operation without pressing while adding.

また、本発明のスライド式の多芯筆記具１は、スライド部材１１、１２の***部１１ａ、１２ａの頂面に、軸筒先端方向に向かって延びる凹部Ｈを形成することによって、***部１１ａ、１２ａを操作する時に、回転方向Ｄへの力が加わっても、凹部Ｈによって***部１１ａ、１２ａから指が外れ難いため、強く前軸２又は後軸３を把持する必要がない。   Further, the slide type multi-core writing instrument 1 of the present invention is formed with a raised portion 11a, by forming a recess H extending toward the tip of the shaft tube on the top surface of the raised portions 11a, 12a of the slide members 11, 12. Even when a force in the rotational direction D is applied when operating 12a, it is difficult to remove the finger from the raised portions 11a, 12a by the recess H, so that it is not necessary to strongly grip the front shaft 2 or the rear shaft 3.

また、***部１１ａ、１２ａの頂面に、前軸２の先端開口部２ａ方向に向かって延びる凹部Ｈを形成することによって、***部１１ａ、１２ａの体積が少なくなり、成形時の圧力差や固化する冷却時間差によって、***部１１ａ、１２ａにヒケや歪が発生し難くすることができる。   Further, by forming the concave portion H extending in the direction of the tip opening 2a of the front shaft 2 on the top surface of the raised portions 11a, 12a, the volume of the raised portions 11a, 12a is reduced, and the pressure difference during molding Due to the cooling time difference to be solidified, it is possible to make it difficult to cause sink marks and distortions in the raised portions 11a and 12a.

本発明における***部の頂面に形成する凹部の形状は、特に限定させるものではないが、凹部の壁面を略円弧形状とすることで、弱い力でも指の腹に密着し易く、スムーズに***部を軸筒先端方向にスライドさせることができるので好ましい。また、***部の体積の減少及び指と当接する部分が広がるので、頂面の全面に凹部Ｈを形成することが最も好ましい。   The shape of the concave portion formed on the top surface of the raised portion in the present invention is not particularly limited, but by making the wall surface of the concave portion into a substantially arc shape, it is easy to closely contact the finger pad even with a weak force, and smoothly rises. This is preferable because the portion can be slid in the axial direction. In addition, since the volume of the raised portion is reduced and the portion in contact with the finger is widened, it is most preferable to form the recess H on the entire top surface.

尚、本実施例では、便宜上、摺動体に被係止部や窓部を形成しているが、被係止部や窓部を形成した付設部材を軸筒に一体に形成してもよい。   In the present embodiment, for the sake of convenience, the locked portion and the window portion are formed on the sliding body, but an attachment member formed with the locked portion and the window portion may be formed integrally with the shaft tube.

本発明のスライド式の多芯筆記具は、前述したボールペン２本の多芯筆記具に限定されるものではなく、ボールペン２本、３本や４本、あるいはシャープペンシルとボールペンなど、複数の筆記体を配設したスライド式の多芯筆記具に用いることができる。   The slide type multi-core writing instrument of the present invention is not limited to the above-mentioned two-core multi-pencil writing instrument. It can be used for the slide type multi-core writing instrument provided.
