Description

本発明は、クリップ付の筆記具に関し、さらに詳しくは、筆記具を構成する筒体の側面に設けた支持部にクリップを支承し、弾発部材によりクリップの先端部を筒体の側面側へ常時弾発させる構造のクリップ付筆記具に関する。 The present invention relates to a writing instrument with a clip. More specifically, the clip is supported on a support portion provided on a side surface of a cylindrical body constituting the writing instrument, and a tip end of the clip is always bulleted to a side surface side of the cylindrical body by a resilient member. The present invention relates to a writing instrument with a clip having a structure to emit.

従来からクリップ付筆記具では、実開昭５５−１４８９９０号公報に開示されているように、クリップの挟持力や耐用強度を向上させるために、コイルバネや板バネ等の弾発部材を用いることによって、クリップの先端部を軸筒の側面側へ常時弾発させる構造のものが存在する。この様な筆記具のクリップは、クリップの後方部を軸筒側へ押圧することで弾発部材を弾性変形させ、クリップの先端部を軸筒から離間して、クリップと軸筒との間に被挟持物を挟む構造である。またクリップは、被挟持物を点で挟んだ方が効率のよい挟持力が働くので、クリップの先端部にいわゆる玉部と呼ばれる突起を設けた構造が多く用いられる。
「実開昭５５−１４８９９０号公報」 Conventionally, in a writing instrument with a clip, as disclosed in Japanese Utility Model Laid-Open No. 55-148990, in order to improve clip clamping force and durability, by using a resilient member such as a coil spring or a leaf spring, There is a structure in which the tip portion of the clip is always bulleted toward the side surface side of the shaft cylinder. The clip of such a writing instrument is such that the elastic member is elastically deformed by pressing the rear part of the clip toward the shaft tube side, the tip of the clip is separated from the shaft tube, and the clip is placed between the clip and the shaft tube. It is a structure that sandwiches sandwiched objects. In addition, since a clip has a more efficient clamping force when a clip is sandwiched between points, a structure in which a so-called ball portion is provided at the tip of the clip is often used.
"Japanese Utility Model Publication No. 55-148990"

ところで前述したクリップの玉部は、例えば胸ポケットに装着した筆記具が抜け落ち難くするように、玉部の前端面及び後端面を筒体の側面に対して起立させた状態として、被挟持物に対して突起が引っ掛かり易く、ズレ難い形状とすることが望ましい。しかしながら、玉部の前端面を筒体の側面に対して起立させたものでは、クリップの後端部を押圧しないで被挟持物である胸ポケットへ挟持した場合に、クリップの突起の前端面がポケットの縁に当接して、被挟持物がクリップと軸筒との間へ進入することを妨げてしまったり、またポケットの生地を傷めてしまうという問題が生じてしまう。 By the way, the ball part of the clip described above is in a state where the front end surface and the rear end surface of the ball part are raised from the side surface of the cylindrical body so that the writing instrument attached to the breast pocket is difficult to come off. Therefore, it is desirable that the protrusions be easily caught and have a shape that is difficult to shift. However, in the case where the front end surface of the ball portion is erected with respect to the side surface of the cylinder, the front end surface of the protrusion of the clip is not clamped when the rear end portion of the clip is held in the chest pocket as the object to be clamped. Abutting on the edge of the pocket prevents the object to be sandwiched from entering between the clip and the shaft tube, and also causes a problem that the pocket fabric is damaged.

本発明はこうした問題を鑑みて、クリップで挟んだ被挟持物がズレ難く、さらにクリップの後端部を押圧せずとも胸ポケット等の被挟持物を簡単に挟持することができる構造のクリップ付筆記具を提供することを目的とする。 In view of such problems, the present invention is provided with a clip having a structure in which an object to be sandwiched between clips is difficult to shift, and an object to be sandwiched such as a breast pocket can be easily sandwiched without pressing the rear end of the clip. The purpose is to provide writing instruments.

"1. In a writing instrument with a clip having a structure in which a clip is supported on a support portion provided on a side surface of a cylindrical body constituting a writing instrument, and a tip of the clip is constantly bulleted by a resilient member toward a side surface of the cylindrical body. The tip of the clip is provided with an inclined surface that is inclined forward and away from the side surface of the cylindrical body, and a front end surface and a rear end surface stand up with respect to the side surface of the cylindrical body behind the inclined surface. A bulging portion provided with a ball portion that is in a state and having a reverse inclined surface inclined in a direction away from the side surface of the cylindrical body from the front side to the rear side on the side surface of the cylindrical body; A writing instrument with a clip, which is provided at an opposite position.
2. The writing instrument with a clip according to 1, wherein the object to be clamped is sandwiched between a front end surface of the ball portion and a rear end surface of the bulging portion. Is.

本発明において、クリップの先端部に設ける玉部と筒体に設ける膨出部との位置関係は、被挟持物の端部が膨出部の傾斜面を乗り越えた段階で、被挟持物の端部がクリップの玉部の下を通過できる状態に設定することが肝要である。またクリップの先端部の傾斜面と筒体の膨出部の逆傾斜面との位置関係は、被挟持物が筒体とクリップとの間に進入し易くさせるように、互いの斜面が対向する位置に設定する。またさらに、筒体の側面に、第二の膨出部をクリップの玉部に隣接させて設けることによって、クリップの挟持力をさらに向上させることもできる。この場合、第二の膨出部が被挟持物の進入を妨げないように、第二の膨出部の高さを前方にある膨出部の高さと同じかそれより低いものとする。 In the present invention, the positional relationship between the ball portion provided at the tip portion of the clip and the bulging portion provided in the cylindrical body is such that the end of the object to be clamped is at the stage where the end of the object to be clamped has overcome the inclined surface of the bulging portion. It is important to set the part so that it can pass under the ball part of the clip. In addition, the positional relationship between the inclined surface of the tip of the clip and the reverse inclined surface of the bulging portion of the cylinder is such that the inclined surfaces face each other so that the object to be clamped can easily enter between the cylinder and the clip. Set to position. Furthermore, the clip clamping force can be further improved by providing the second bulge portion adjacent to the ball portion of the clip on the side surface of the cylindrical body. In this case, the height of the second bulging portion is equal to or lower than the height of the bulging portion in front so that the second bulging portion does not hinder the entry of the object to be sandwiched.

尚、玉部の前端面及び後端面は、筒体の側面に対して起立した状態とし、具体的には筒体の側面に対して５０度〜９０度の傾きに設定するとよい。またクリップの先端部の傾斜面及び筒体の膨出部の逆傾斜面は、筒体の側面に対して５度〜３０度の傾きに設定するとよい。 It should be noted that the front end surface and the rear end surface of the ball portion are in an upright state with respect to the side surface of the cylindrical body, and specifically, may be set at an inclination of 50 to 90 degrees with respect to the side surface of the cylindrical body. Moreover, the inclined surface of the tip part of the clip and the reverse inclined surface of the bulging part of the cylindrical body may be set to an inclination of 5 to 30 degrees with respect to the side surface of the cylindrical body.

本発明によるクリップ付筆記具は、筒体に設けた膨出部の逆傾斜面が被挟持物をクリップと筒体との間に進入させる案内役となるので、クリップの玉部の前端面が被挟持物の進入の妨げにならず、クリップの後端部を押圧せずとも被挟持物をクリップと筒体との間に滑り込ませるように挟持することができるものとなる。また、クリップの玉部の前端面及び後端面が筒体の側面に対して起立させてあることから、挟持した状態で玉部が被挟持物に引っ掛かかり易くズレ難いものとなる。また、玉部の前端面と膨出部の後端面との間に被挟持物を挟持させることにより、さらに強固に挟持を行うことができるものとなる。 In the writing instrument with a clip according to the present invention, since the reverse inclined surface of the bulging portion provided in the cylinder serves as a guide for allowing the object to be sandwiched between the clip and the cylinder, the front end surface of the ball part of the clip is covered. It does not hinder the entry of the sandwiched object, and the object to be sandwiched can be sandwiched between the clip and the cylinder without pressing the rear end of the clip. In addition, since the front end surface and the rear end surface of the ball portion of the clip are raised with respect to the side surface of the cylindrical body, the ball portion is easily caught on the object to be sandwiched and is not easily displaced. In addition, the object to be sandwiched is sandwiched between the front end surface of the ball portion and the rear end surface of the bulging portion, whereby the clamping can be performed more firmly.

次に図面を参照しながら、本発明のクリップ付筆記具の実施例を説明するが、本発明は以下の実施例に限定されるものではない。また図中の同じ部材、同じ部品については、同じ符号としてある。本実施例では、筆記先端がある側を前方とし反対側を後方として表現する。 Next, examples of the writing instrument with a clip of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following examples. In addition, the same members and the same parts in the drawings are denoted by the same reference numerals. In this embodiment, the side with the writing tip is expressed as the front and the opposite side is expressed as the back.

図１は本発明の第一の実施例であるクリップ付筆記具の側面図であり、図２，図３は本発明の要部斜視図である。図２はクリップを閉じた状態で、図３はクリップを開いた状態である。筆記具１は軸筒２を筒体である前軸３と後軸４とで構成し、後軸４の後部にクリップ５を配設してある。クリップ５は表面板５ａと表面板５ａから後軸４に向かって垂設した側面板５ｂとを有し、側面板５ｂに形成した丸孔５ｃを後軸４に形成した支持部４ａの支軸４ｂに軸支させると共に、後軸４の後部に設けた平地部４ｃと表面板５ａの裏面との間へ弾性部材である、コイルスプリング６を配設し、クリップ５の先端部５ｄを後軸の側面に常時弾発させて当接してある。筆記具１は後軸４の後部に配設したスライダー１ａを摺動させることで、前軸３の先端開口部３ａから筆記先端であるボールペンチップ（図示せず）を出没させることができる。 FIG. 1 is a side view of a writing instrument with a clip according to a first embodiment of the present invention, and FIGS. 2 and 3 are perspective views of essential parts of the present invention. 2 shows a state in which the clip is closed, and FIG. 3 shows a state in which the clip is opened. In the writing instrument 1, a shaft cylinder 2 is constituted by a front shaft 3 and a rear shaft 4 which are cylindrical bodies, and a clip 5 is disposed at a rear portion of the rear shaft 4. The clip 5 has a surface plate 5a and a side plate 5b suspended from the surface plate 5a toward the rear shaft 4, and a support shaft of the support portion 4a formed on the rear shaft 4 with a round hole 5c formed in the side plate 5b. The coil spring 6 as an elastic member is disposed between the flat ground portion 4c provided at the rear portion of the rear shaft 4 and the back surface of the front plate 5a, and the tip portion 5d of the clip 5 is disposed at the rear shaft. It always abuts against the side of the The writing instrument 1 can slide a slider 1a disposed at the rear part of the rear shaft 4 so that a ballpoint pen tip (not shown), which is the writing tip, can appear and disappear from the front end opening 3a of the front shaft 3.

また、図２，図３に示すように、クリップ５の先端部５ｄには、傾斜面５ｅと傾斜面５ｅの後方に位置する玉部５ｆを設けてある。玉部５ｆは後軸４の側面に対して起立した前端面５ｇと後端面５ｈとを有している。また後軸４の側面には、クリップ５の傾斜面５ｅと対向する位置に逆傾斜面４ｅを位置させた膨出部４ｆを形成してある。図４は本実施例の玉部近傍を側面から見た拡大図である。傾斜面５ｅは後軸４の側面と平行する仮想線Ｌに対して、前方から後方へ向かって２０度の角度で緩やかに傾斜させてある。逆傾斜面４ｅは後軸４の側面に対して、後方から前方へ向かって１０度の角度で緩やかに傾斜させてある。また玉部５ｆは前端面５ｇと後端面５ｈとが後軸４の側面に対して、対称的に６０度で傾斜させてある。尚、前端面５ｇと膨出部４ｆの後端面４ｇとは平行するように隣接させてある。 As shown in FIGS. 2 and 3, the tip 5d of the clip 5 is provided with an inclined surface 5e and a ball portion 5f positioned behind the inclined surface 5e. The ball portion 5f has a front end surface 5g and a rear end surface 5h that stand up with respect to the side surface of the rear shaft 4. Further, on the side surface of the rear shaft 4, a bulging portion 4 f in which the reverse inclined surface 4 e is positioned at a position facing the inclined surface 5 e of the clip 5 is formed. FIG. 4 is an enlarged view of the vicinity of the ball portion of this embodiment as viewed from the side. The inclined surface 5e is gently inclined at an angle of 20 degrees from the front to the rear with respect to a virtual line L parallel to the side surface of the rear shaft 4. The reverse inclined surface 4e is gently inclined with respect to the side surface of the rear shaft 4 at an angle of 10 degrees from the rear to the front. Further, in the ball portion 5f, the front end surface 5g and the rear end surface 5h are inclined at 60 degrees symmetrically with respect to the side surface of the rear shaft 4. The front end face 5g and the rear end face 4g of the bulging portion 4f are adjacent to each other in parallel.

図５は被挟持物である胸ポケットを、後軸とクリップとの間に滑り込ませるように差し込んで挟持する時の図である。図５に示すように被挟持物である胸ポケット１０は、逆傾斜面４ｅによってクリップ５の傾斜面５ｅを押し開きながら玉部５ｆの下へ滑り込み、クリップ５と後軸４との間に入り込み挟持される。図６はクリップで被挟持物を挟持した状態の図である。図６の状態でクリップ５の先端部５ｄには、コイルスプリング（図示せず）の弾発力による矢印Ａの力が掛かっており、胸ポケット１０はクリップ５の玉部５ｆと後軸４の側面との間に挟持され、さらに玉部５ｆの前端面５ｇと膨出部４ｆの後端面４ｇとの間で挟持される。この様にして筆記具を胸ポケットに装着した状態にすると、胸ポケットを挟持しているクリップが簡単にズレることはないので筆記具が簡単に脱落してしまう心配がなかった。しかしながら、図７に示すように、指でクリップ５の後端部５ｉを後軸４の側面方向へ押圧することで、コイルスプリング６を圧縮し、クリップ５を開いて胸ポケットから簡単に取り外すことができる。 FIG. 5 is a view when a breast pocket as an object to be clamped is inserted and clamped so as to be slid between the rear shaft and the clip. As shown in FIG. 5, the breast pocket 10 that is the object to be clamped slides under the ball portion 5 f while pushing open the inclined surface 5 e of the clip 5 by the reverse inclined surface 4 e and enters between the clip 5 and the rear shaft 4. It is pinched. FIG. 6 is a diagram showing a state in which an object to be clamped is clamped by a clip. In the state shown in FIG. 6, the tip 5 d of the clip 5 is subjected to the force indicated by the arrow A due to the elastic force of a coil spring (not shown), and the chest pocket 10 is connected to the ball 5 f of the clip 5 and the rear shaft 4. It is clamped between the side surfaces and is further clamped between the front end surface 5g of the ball portion 5f and the rear end surface 4g of the bulging portion 4f. When the writing instrument was put in the chest pocket in this manner, the clip holding the breast pocket was not easily displaced, so there was no concern that the writing instrument would easily fall off. However, as shown in FIG. 7, the coil spring 6 is compressed by pressing the rear end portion 5 i of the clip 5 with the finger toward the side surface of the rear shaft 4, and the clip 5 is opened and easily removed from the breast pocket. Can do.

図８は第二の実施例の要部であるクリップ先端近傍の図で、クリップで被挟持物を挟持した状態の図である。後軸４に形成した膨出部４ｆの後方で且つクリップ５の玉部５ｆの後方にて隣接した位置となる箇所に第二の膨出部４ｈを設けてある以外は前述の第一の実施例と同様である。第二の膨出部４ｈの高さは膨出部４ｆの高さより低く形成してある。したがって、クリップ５と後軸４との間に入り込む胸ポケット１０の進入を第二の膨出部４ｈが妨げてしまうことはなかった。尚、第二の膨出部４ｈの前端面４ｉと後端面４ｊとは後軸４の側面に対して６０度で傾斜させている。 FIG. 8 is a view of the vicinity of the tip of the clip, which is a main part of the second embodiment, and shows a state in which the object to be clamped is clamped by the clip. The first embodiment described above, except that the second bulging portion 4h is provided at a position that is adjacent to the rear of the bulging portion 4f formed on the rear shaft 4 and behind the ball portion 5f of the clip 5. Similar to the example. The height of the second bulging portion 4h is formed lower than the height of the bulging portion 4f. Therefore, the second bulging portion 4 h did not prevent the breast pocket 10 entering between the clip 5 and the rear shaft 4 from entering. The front end surface 4i and the rear end surface 4j of the second bulging portion 4h are inclined at 60 degrees with respect to the side surface of the rear shaft 4.
