Description

本発明は、マーキングペンなどの筆記具に関する。 The present invention relates to writing implements such as marking pens.

従来、マーキングペンなどの筆記具において、先端に設けられインクが誘導される筆記部は、先端が露出している。そのため、定規を用いて線を引く場合に、定規と筆記部の先端とが接触して、定規における筆記部との接触部分にインクが付着し、定規を汚してしまうことがあった。更には、繰り返し定規と接触することで、筆記部が破損してしまう可能性がある。 2. Description of the Related Art Conventionally, in a writing instrument such as a marking pen, the tip of a writing part provided at the tip through which ink is guided is exposed. Therefore, when a line is drawn using a ruler, the tip of the ruler and the writing part come into contact with each other, and ink adheres to the contact portion of the ruler with the writing part, which may stain the ruler. Furthermore, repeated contact with the ruler may damage the writing section.

これに対して、定規を用いて線を引く場合に、定規への筆記部のインクの付着を防止できる筆記具が提案されている(例えば、特許文献1及び2参照)。
特許文献1に記載の筆記具は、筆記部を保持する保持体に2つの貫通孔や2つの溝を設けると共に、筆記部の途中に2股に分けた部分を形成することで、筆記部の2股に分けた部分を、2つの貫通孔や2つの溝に配置して、筆記部が保持体の側面の外側に配置されないように構成されている。これにより、定規を用いて線を引く場合に、保持体の側方の端部が定規に接触するため、筆記部の露出された部分が定規に接触しないように構成されている。
特許文献2に記載の筆記具は、筆記部の外面に被覆部材を設けて、被覆部分において、定規に接触する部分を残した状態で、先端の筆記する部分を削って露出するように構成されている。被覆部材が設けられた部分が定規に接触するため、筆記部の露出された部分が定規に接触しないように構成されている。
In response to this, there has been proposed a writing instrument that can prevent ink from sticking to the writing portion of the ruler when drawing a line using the ruler (see, for example, Patent Documents 1 and 2).
In the writing instrument described in Patent Document 1, two through holes and two grooves are provided in a holding body that holds the writing part, and two parts of the writing part are formed by forming a bifurcated portion in the middle of the writing part. The crotch part is arranged in two through holes or two grooves so that the writing part is not arranged outside the side surface of the holder. As a result, when a line is drawn using a ruler, the side ends of the holding body come into contact with the ruler, so that the exposed portion of the writing section does not come into contact with the ruler.
The writing instrument described in Patent Document 2 is configured such that a covering member is provided on the outer surface of the writing part, and the part to be written at the tip of the covering part is shaved off while leaving the part that contacts the ruler. there is Since the part provided with the covering member contacts the ruler, the exposed part of the writing part is configured not to contact the ruler.

The ink guiding portion 7 is installed on the one side installation surface 472 .

一対の先端側リブ481,481は、先端側設置面471から先端側に立設されると共に筆記具本体2の軸方向Jに交差する方向に対向する。一対の一側面側リブ482,482は、一側面側設置面472から一側面側に立設されると共に筆記具本体2の軸方向Jに交差する方向に対向する。 The pair of tip-side ribs 481 , 481 are erected on the tip side from the tip-side installation surface 471 and face each other in a direction crossing the axial direction J of the writing instrument main body 2 . The pair of one side ribs 482 , 482 are erected on one side from the one side installation surface 472 and face each other in a direction crossing the axial direction J of the writing instrument main body 2 .

先端側リブ481は、図8Aに示すように、先端側リブ481の先端側の部分の外面と筆記部8の幅狭筆記部81の先端側の部分の外面とを繋ぐ傾斜線Kが、筆記具本体2の軸方向Jに対して、角度θの範囲に位置されるように形成されることが好ましい。筆記具本体2の軸方向Jに対する傾斜線Kの角度θは、例えば、45°以下が好ましく、35°以下が更に好ましい。 As shown in FIG. 8A, the distal rib 481 has an inclined line K that connects the outer surface of the tip side portion of the tip side rib 481 and the outer surface of the tip side portion of the narrow writing portion 81 of the writing unit 8. It is preferably formed so as to be positioned within an angle θ with respect to the axial direction J of the main body 2 . The angle θ of the inclined line K with respect to the axial direction J of the writing instrument main body 2 is, for example, preferably 45° or less, more preferably 35° or less.

これにより、先端側リブ481が筆記部8の幅狭筆記部81の先端側の部分よりも後方側に位置するため、筆記部8の幅狭筆記部81の先端の部分は、露出する部分が多くなる。よって、先端側リブ481を紙面側に倒すように傾けて筆記具1を使用する場合に、先端側リブ481は、先端側リブ481を紙面側に倒すように筆記具1を傾けても、筆記具本体2の軸方向Jが紙面に対して角度θとなるまで紙面に接触しない。従って、筆記具本体2の軸方向Jに対する傾斜線Kの角度θとすることで、先端側リブ481を紙面側に倒すように傾けた状態での筆記を行い易い。 As a result, the distal end side rib 481 is positioned further rearward than the distal end portion of the narrow writing portion 81 of the writing portion 8, so that the distal end portion of the narrow writing portion 81 of the writing portion 8 is exposed. become more. Therefore, when the writing instrument 1 is used with the tip-side ribs 481 tilted toward the paper surface, the tip-side ribs 481 do not move even when the writing instrument 1 is tilted so as to tilt the tip-side ribs 481 toward the paper surface. does not touch the paper surface until the axial direction J of becomes an angle θ with respect to the paper surface. Therefore, by setting the angle θ of the inclined line K with respect to the axial direction J of the writing instrument main body 2, it is easy to write in a state in which the tip side rib 481 is tilted toward the paper surface.

特に、本発明の筆記具1は、筆記時に可視部Vを通して筆記方向を視認できるため、筆記具1をより倒した状態で筆記を行うことがある。このような場合でも、先端側リブ481を紙面側に倒すように傾けた状態での筆記を行い易いため、先端側リブ481を紙面側に倒した状態で、可視部Vを通して筆記方向を視認しながら、より好適に筆記を行うことができる。 In particular, with the writing instrument 1 of the present invention, the writing direction can be visually recognized through the visible portion V during writing, so writing may be performed with the writing instrument 1 tilted more. Even in such a case, since it is easy to write with the tip side rib 481 tilted toward the paper, the writing direction can be visually recognized through the visible portion V with the tip side rib 481 tilted toward the paper. While, writing can be performed more suitably.

It constitutes a regulation mechanism that regulates the movement of The narrow writing portion 81 of the writing portion 8 is assembled to the narrow holding portion 411 of the distal end side open holding portion 41 from one side surface side of the distal end side open holding portion 41 .

一側面側開放保持部42は、保持部4の一側面側が開放されることで形成され、筆記具本体2の軸方向Jに延びる溝状に形成される。一側面側開放保持部42は、一対の一側面側リブ482により構成される。一側面側開放保持部42は、一対の一側面側リブ482の間にインク誘導部7を挟み込んで嵌合することで、インク誘導部7を保持する。 The one side open holding part 42 is formed by opening one side of the holding part 4 and is formed in a groove shape extending in the axial direction J of the writing instrument main body 2 . The one side open holding portion 42 is configured by a pair of one side ribs 482 . The one side open holding portion 42 holds the ink guiding portion 7 by sandwiching and fitting the ink guiding portion 7 between the pair of one side ribs 482 .

他側面閉鎖部43は、図4及び図5に示すように、保持部4の他側面を閉鎖する。他側面閉鎖部43は、壁部431と、規制突起432と、を有する。 The other side closing part 43 closes the other side of the holding part 4, as shown in FIGS. The other side closing portion 43 has a wall portion 431 and a restricting protrusion 432 .

壁部431は、他側面閉鎖部43の軸方向Jの先端において、先端側に半円弧状に突出する。壁部431は、図3及び図7Bに示すように、太字側保持体3の他側面側に、筆記体を筆記可能に筆記部8の先端を先端側に突出させた状態で筆記部8の他側面に沿って配置される。壁部431は、筆記部8の他側面が露出する範囲を、筆記時に定規が筆記部8に接触しない範囲に制限するように、軸方向Jの先端側に突出する。 The wall portion 431 protrudes in a semicircular arc shape toward the tip end of the other side closed portion 43 in the axial direction J. As shown in FIG. As shown in FIGS. 3 and 7B, the wall portion 431 is provided on the other side surface of the bold-face holding body 3 so that the tip of the writing portion 8 protrudes toward the tip side so that the writing portion 8 can be written. placed along the other side. The wall portion 431 protrudes toward the tip side in the axial direction J so as to limit the range where the other side surface of the writing section 8 is exposed to a range in which the ruler does not come into contact with the writing section 8 during writing.

本実施形態においては、保持部4の先端側においては、壁部431が、保持部4の他側面閉鎖部43から軸方向Jの先端側に突出して形成され、先端側リブ481が、筆記部8の幅狭筆記部81の先端側の部分よりも後方側に位置する。そのため、保持部4の先端側が開放されると共に、壁部431が軸方向Jの先端側に突出して形成される。これにより、保持部4の先端側においては、筆記部8の先端の部分は、露出する部分が多くなる。よって、先端側リブ481を紙面側に倒すように傾けた状態での筆記を行い易い。 In this embodiment, on the tip side of the holding part 4, the wall part 431 is formed so as to protrude from the other side closed part 43 of the holding part 4 to the tip side in the axial direction J, and the tip side rib 481 is formed on the writing part. It is located on the rear side of the tip side portion of the narrow writing portion 81 of 8 . Therefore, the distal end side of the holding portion 4 is opened, and the wall portion 431 is formed to protrude toward the distal end side in the axial direction J. As shown in FIG. As a result, on the tip end side of the holding part 4, the tip part of the writing part 8 is more exposed. Therefore, it is easy to write in a state in which the tip side rib 481 is tilted toward the paper surface.

筆記部8は、幅方向Wの幅W1(長さ)(図7A参照)が、厚さ方向Tの幅T1(長さ)(図8A参照)よりも大きく形成される(W1>T1)。より詳細には、本実施形態においては、筆記部8の幅方向Wの幅W1は、図7Aに示すように、幅方向Wにおいて、筆記部8の先端に沿う筆記具本体2の軸方向Jに傾斜する方向の長さである。
筆記部8は、幅方向Wの幅W1(描線幅、紙面に接触する部分の幅)が太く形成され、好ましくは2mm以上の描線幅となる筆記部であり、更に好ましくは3mm以上の描線幅となる筆記部である。
The writing portion 8 is formed so that the width W1 (length) in the width direction W (see FIG. 7A) is larger than the width T1 (length) in the thickness direction T (see FIG. 8A) (W1>T1). More specifically, in the present embodiment, the width W1 of the writing section 8 in the width direction W extends in the axial direction J of the writing instrument main body 2 along the tip of the writing section 8 in the width direction W, as shown in FIG. 7A. It is the length in the direction of inclination.
The writing portion 8 is a writing portion formed with a large width W1 in the width direction W (the width of a drawn line, the width of a portion in contact with the paper surface), preferably a drawn line width of 2 mm or more, and more preferably a drawn line width of 3 mm or more. This is the writing section.

筆記部8の先端は、図7Aに示すように、幅方向Wの一方側(図7Aにおける下方側)が他方側(図7Aにおける上方側)よりも筆記具本体2側に位置するように筆記具本体2の軸方向Jに対して傾斜して形成される。壁部431は、筆記部8の幅方向Wの一方側に配置される。 As shown in FIG. 7A, the tip of the writing part 8 is positioned closer to the writing instrument main body 2 than the other side (upper side in FIG. 7A) in the width direction W (lower side in FIG. 7A). 2 is inclined with respect to the axial direction J.

壁部431は、傾斜する筆記部8の先端の両側面のうち、筆記時に手前側にくる側面側に設けられることが好ましい。壁部431が筆記部8の幅方向Wの一方側に配置されることで、壁部431を筆記時に手前側にくる側面側に設けることが可能となり、自然な持ち方で、壁部431が定規に接触した状態で筆記可能となる。 It is preferable that the wall portion 431 is provided on the side surface of the inclined tip of the writing portion 8 that is on the front side during writing. By arranging the wall portion 431 on one side of the writing portion 8 in the width direction W, it becomes possible to provide the wall portion 431 on the side surface that comes to the near side when writing, and the wall portion 431 can be held in a natural way. It becomes possible to write while in contact with the ruler.

図9に示すように、壁部431が先端側に突出する長さは、壁部431の先端431aの位置が、筆記部8における幅方向Wの壁部431側の端部の先端8aの位置よりも、例えば、定規100の厚さよりも短い距離Aだけ、後方側に位置するように設定される。「定規100の厚さよりも短い距離A」は、筆記面である筆記部8の先端8aから1.5mm以下であり、好ましくは1.0mm以下であり、さらに好ましくは0.5mm以下である。これにより、定規100を用いて線を引く場合に、壁部431の側方の端部が定規に接触するため、筆記部8の露出された部分が定規に接触しない。よって、定規100を用いて線を引く場合に、定規にインクが付着することが抑制されるため、定規100が汚れることを防止でき、かつ、筆記部8と定規100が擦れることにより生じる筆記部8の破損を防止することができる。 As shown in FIG. 9 , the length by which the wall portion 431 protrudes toward the tip side is such that the position of the tip 431 a of the wall portion 431 corresponds to the position of the tip 8 a of the end portion of the writing portion 8 on the wall portion 431 side in the width direction W. , for example, by a distance A shorter than the thickness of the ruler 100 . The "distance A shorter than the thickness of the ruler 100" is 1.5 mm or less, preferably 1.0 mm or less, and more preferably 0.5 mm or less from the tip 8a of the writing portion 8, which is the writing surface. As a result, when the ruler 100 is used to draw a line, the side ends of the walls 431 come into contact with the ruler, so the exposed portion of the writing section 8 does not come into contact with the ruler. Therefore, when a line is drawn using the ruler 100, adhesion of ink to the ruler is suppressed, so that the ruler 100 can be prevented from being soiled, and a writing portion caused by rubbing between the writing portion 8 and the ruler 100 can be prevented. 8 can be prevented from being damaged.

次に、本実施形態に係る筆記具1を組み立てる方法について説明する。
まず、図4及び図5に示すように、太字側筆記芯6を太字側保持体3に組み付ける。具体的には、太字側筆記芯6を、一側面側から太字側保持体3に組み付けることで、先端側開放保持部41において、一対の先端側リブ481で構成された幅狭保持部411により先端側への移動が規制された状態で一対の先端側リブ481と先端側設置面471とにより筆記部8が挟持されると共に、一側面側開放保持部42において、一対の一側面側リブ482の間にインク誘導部7が嵌合される。
Next, a method for assembling the writing instrument 1 according to this embodiment will be described.
First, as shown in FIGS. 4 and 5, the writing lead 6 on the bold side is attached to the holder 3 on the bold side. Specifically, by assembling the bold-face writing lead 6 to the bold-face holding body 3 from one side, the narrow holding portion 411 formed of a pair of tip-side ribs 481 in the tip-end open holding portion 41 The writing part 8 is sandwiched between the pair of tip-side ribs 481 and the tip-side installation surface 471 in a state where movement to the tip side is restricted, and the pair of one-side ribs 482 are held in the one-side open holding part 42 . The ink guide portion 7 is fitted between the .

これにより、略L字形状の太字側筆記芯6を太字側保持体3の幅方向Wの一側面側から挿入するだけで、太字側筆記芯6を太字側保持体3に簡単に組み付けることができる。
太字側筆記芯6は、略L字形状に形成されるため、コ字形状に形成するよりも、太字側保持体3の可視部Vを大きく設けることができる。
As a result, only by inserting the substantially L-shaped bold-type writing lead 6 from one side surface of the bold-type holding body 3 in the width direction W, the bold-type writing lead 6 can be easily assembled to the bold-type holding body 3. can.
Since the bold-face writing lead 6 is formed in a substantially L-shape, the visible portion V of the bold-face holding body 3 can be provided larger than in the case of forming it in a U-shape.

また、筆記部8の幅狭筆記部81が先端側開放保持部41の幅狭保持部411に配置されることで、太字側筆記芯6の軸方向Jの先端側への移動が規制される。また、規制突起432及び先端側設置面471により構成された係合規制部49に、筆記部8の係合凸部83が係合されることで、幅方向Wの他側面側において、筆記部8の先端側及び後方側への移動が規制される。これにより、太字側保持体3の軸方向Jへの太字側筆記芯6(筆記部8)の抜けを防止することができる。 Further, by arranging the narrow writing portion 81 of the writing portion 8 in the narrow holding portion 411 of the tip side open holding portion 41, movement of the bold side writing lead 6 toward the tip side in the axial direction J is restricted. . In addition, by engaging the engaging convex portion 83 of the writing portion 8 with the engaging restricting portion 49 constituted by the restricting protrusion 432 and the tip end installation surface 471, the writing portion can be Movement of 8 to the tip side and the rear side is restricted. As a result, it is possible to prevent the bold-face-side writing core 6 (writing portion 8) from coming off in the axial direction J of the bold-face-side holding member 3 .

続けて、図6に示すように、太字側筆記芯6を取り付けた太字側保持体3の取付部5を、筆記具本体2の先端に取り付ける。具体的には、太字側筆記芯6を取り付けた太字側保持体3の取付部5を、先端側から、筆記具本体2の矩形開口251に挿入する。これにより、図8A及び図8Bに示すように、一対の取付凸部51を、一対の突出コ字状部281の嵌合部281aに嵌合させることで、太字側保持体3の取付部5を筆記具本体2に取り付けることができる。 Subsequently, as shown in FIG. 6, the attachment portion 5 of the bold-face holding body 3 to which the bold-face writing core 6 is attached is attached to the tip of the writing instrument main body 2 . Specifically, the attachment portion 5 of the bold-face holding body 3 to which the bold-face writing core 6 is attached is inserted into the rectangular opening 251 of the writing instrument main body 2 from the tip side. 8A and 8B, the pair of mounting protrusions 51 are fitted into the fitting portions 281a of the pair of projecting U-shaped portions 281, whereby the mounting portion 5 of the bold-face holding body 3 is mounted. can be attached to the writing instrument body 2.

Further, since the attachment portion 5 of the bold-face holding member 3 is formed in a plate shape and the rectangular opening 251 of the writing instrument main body 2 is opened in a rectangular shape, the attachment portion 5 of the bold-face holding member 3 is attached to the writing instrument main body 2. It is difficult to rotate against it.

また、筆記具本体2の内部において、筆記具本体2の第1当接面282aには、太字側保持体3の第1段部52の第1段差面521が当接する。また、筆記具本体2の内部において、筆記具本体2の第2当接面283aには、太字側保持体3の第2段部53の第2段差面531が当接する。本実施形態においては、第1当接面282a及び第2当接面283aが、筆記具本体2の径方向の内側において筆記具本体2の先端よりも後方側に配置される。これにより、段差面521,531と当接面282a,283aとの当接部分が、筆記具本体2の内部に位置されるため、太字側保持体3の取付部5と筆記具本体2との隙間が見えにくい。 Further, inside the writing instrument body 2 , the first step surface 521 of the first stepped portion 52 of the bold-face side holding body 3 abuts against the first contact surface 282 a of the writing instrument body 2 . Further, inside the writing instrument body 2 , the second step surface 531 of the second stepped portion 53 of the bold-face side holding body 3 abuts against the second contact surface 283 a of the writing instrument body 2 . In the present embodiment, the first contact surface 282a and the second contact surface 283a are arranged radially inside the writing instrument body 2 and behind the tip of the writing instrument body 2 . As a result, the abutting portions between the stepped surfaces 521 and 531 and the abutting surfaces 282a and 283a are positioned inside the writing instrument main body 2, so that a gap between the mounting portion 5 of the bold-face side holder 3 and the writing instrument main body 2 is formed. Hard to see.

また、図7Bに示すように、環状面部25の矩形開口251のインク誘導部7が配置される側の筒部24の内面の軸方向Jの先端側において、先端から後方側に向かうに従って突出するように傾斜して形成される案内傾斜突出部284を設けることで、案内傾斜突出部284により、中綿29の径方向の中心側にインク誘導部7を案内できるため、中綿29からインク誘導部7に、安定してインクを供給できる。 Further, as shown in FIG. 7B, on the tip side in the axial direction J of the inner surface of the cylindrical portion 24 on the side where the ink guide portion 7 of the rectangular opening 251 of the annular surface portion 25 is arranged, the tip protrudes rearward from the tip. By providing the inclined guiding protrusion 284 formed in such a manner that the guiding inclined protrusion 284 can guide the ink guiding portion 7 toward the radial center side of the batting 29 , the ink guiding portion 7 can be guided from the batting 29 to the center of the batting 29 in the radial direction. Ink can be stably supplied to
