Description
【０００１】[0001]
本考案は、軸筒とクリップとの双方が樹脂製からなる筆記具に係り、特にクリ ップの軸筒に対する取付構造に関する。 The present invention relates to a writing instrument in which both the barrel and the clip are made of resin, and more particularly to a mounting structure of the clip to the barrel.
【０００２】[0002]
従来から軸筒とクリップとを合成樹脂材料を用いて夫々成形し、組み立てによ りクリップを軸筒に取り付け装着することで構成される筆記具は知られている。 Conventionally, there has been known a writing implement formed by molding a shaft cylinder and a clip using a synthetic resin material, and assembling and attaching the clip to the shaft cylinder.
【０００３】[0003]
ところで、従来から知られているこの種の筆記具において、図７に例示したよ うに、クリップ100を構成するクリップ部101とリング部102とを連結する連結部1 03の厚み（肉厚）をクリップ部101の厚みと同じ程度にしている。これは、厚み の違いによる成形時の材料引けを防ぐためである。 例えば、成形型内に注入された材料の固化速度が遅い肉厚部分には固化速度が 速い肉薄部分側に材料が引張られる材料の引け現象が起る。この引け現象が起る と、材料が引張られた部分の表面には凹みが発生する。詳しくは連結部との連結 基部に位置するクリップ部の表面部分には材料不足により凹みが発生する。 従って、クリップ部とリング部とを連結する連結部の厚みはクリップ部の厚み と同じ程度にする必要があった。 By the way, in a conventionally known writing instrument of this type, as shown in FIG. 7, the thickness (wall thickness) of the connecting portion 103 connecting the clip portion 101 and the ring portion 102 constituting the clip 100 is determined by the clip. The thickness is approximately the same as the thickness of the portion 101. This is to prevent material shrinkage during molding due to differences in thickness. For example, in a thick portion where the solidification speed of the material injected into the mold is low, a material pulling phenomenon occurs in which the material is pulled toward the thin portion where the solidification speed is high. When this shrinkage phenomenon occurs, a depression occurs on the surface of the portion where the material is pulled. More specifically, the surface of the clip portion located at the base of the connection with the connection portion is dented due to insufficient material. Therefore, the thickness of the connecting portion connecting the clip portion and the ring portion needs to be approximately the same as the thickness of the clip portion.
【０００４】 しかし乍ら、連結部のクリップ部との連結基部にはクリップ部をノットや衣服 のポケット等に差し込む際の応力が集中するために、クリップ部の幅に対して同 クリップ部を連結支持する連結部の連結面積が狭い従来の筆記具においては繰り 返し受ける応力により連結部が短期間で塑性変形する等の材料疲労を起し、連結 部との連結基点を支点とするクリップ部のバネ作用（挟み作用）が劣ってしまう 。即ち、クリップ機能が劣ってしまったり、最悪の場合には連結部との連結基点 からクリップ部が折れてしまう等の耐久性の面において問題があった。However, since stress when the clip portion is inserted into a knot or a pocket of clothes is concentrated on a connection base portion of the connection portion with the clip portion, the clip portion is connected to the width of the clip portion. In a conventional writing instrument that has a small connecting area for the connecting part to be supported, repeated stress causes material fatigue such as plastic deformation of the connecting part in a short period of time. The action (pinching action) is inferior. That is, there is a problem in terms of durability such that the clip function is inferior, or in the worst case, the clip portion is broken from a connection base point with the connection portion.
【０００５】 尚、連結部の耐久強度を高める手段として、当該連結部を含めてクリップ部の 厚さを厚くすることも考えられるが、クリップ部をあまり厚くすると、クリップ 部が硬くなって本来のバネ作用（クリップ機能）が得られなくなる虞れがあり、 クリップ部の厚さにはバネ作用を保つために制限ある。As a means for increasing the durability of the connecting portion, it is conceivable to increase the thickness of the clip portion including the connecting portion. However, if the clip portion is too thick, the clip portion becomes hard and the original portion becomes hard. There is a possibility that the spring function (clip function) cannot be obtained, and the thickness of the clip portion is limited in order to maintain the spring function.
【０００６】 本考案はこの様な従来事情に鑑みてなされたもので、その目的とする処は、ク リップ部をリング部に対して十二分の耐久強度を持って連結することができ、し かも、リング部を軸筒に圧入せしめた後においてはリング部が軸筒の周方向に回 らないように改良した筆記具を提供することにある。The present invention has been made in view of such a conventional situation, and its purpose is to connect the clip portion to the ring portion with sufficient durability. Another object of the present invention is to provide a writing instrument improved so that the ring does not rotate in the circumferential direction of the barrel after the ring is pressed into the barrel.
【０００７】[0007]
課題を達成するために本考案は、樹脂製軸筒と、この軸筒の後端側に嵌合装着 される樹脂製クリップとからなる筆記具に於いて、クリップは、クリップ部と、 このクリップ片を軸筒に取り付けるリング部と、クリップ部とリング部とを連結 する連結部とから構成され、該連結部は、クリップ部の幅内において適宜の間隔 にて該クリップ部と前記リング部とを連結する両側の連結片からなり、この両連 結片をクリップ部の厚さと略同じ程度に形成すると共に、筒方向に貫通状に開口 する肉盗み部を両連結片間に設け、更に、前記リング部の内面と、このリング部 が装着される軸筒の外面との間にはリング回り止め手段を設けて構成してなるこ とである。 In order to achieve the object, the present invention provides a writing instrument comprising a resin barrel and a resin clip fitted and mounted on the rear end side of the barrel, wherein the clip comprises a clip portion, and a clip piece. And a connecting portion connecting the clip portion and the ring portion. The connecting portion connects the clip portion and the ring portion at appropriate intervals within the width of the clip portion. It is composed of connecting pieces on both sides to be connected, the two connecting pieces are formed to have substantially the same thickness as the clip portion, and a stolen portion that opens in a tubular direction is provided between the two connecting pieces. A ring detent means is provided between the inner surface of the ring portion and the outer surface of the shaft cylinder to which the ring portion is attached.
【０００８】 又、本考案は上記リング回り止め手段が、リング部を軸筒に圧入することによ り互いに嵌合掛止し合う凸部と凹部とからなることである。 ここで、凸部をリング部の内面側に形成する場合にはリング部の軸筒に対する 圧入取付方向に対して逆向き方向に突出させた断面略鋸刃状に、又、軸筒の外面 側に形成する場合には前記圧入取付方向に突出させた断面略鋸刃状に形成するこ とが好ましい。 一方、凹部をリング部の内面側に形成する場合にはリング部の軸筒に対する圧 入取付方向に凹ませた断面略鋸刃状に、又、軸筒の外面側に形成する場合には前 記圧入取付方向に対して逆向きに凹ませた断面略鋸刃状に形成することが好まし い。 尚、リング回り止め手段としては、凸部と凹部との関係に限定されるものでは ない。つまり、リング部を軸筒に圧入により取り付ける際にその圧入取付方向に 対しては負荷抵抗が余り掛からないように、そして、圧入した後においては互い に嵌合掛止し合ってリング部が軸筒の周方向に回らないようにしっかりと受け止 めることができる形状・構造であれば良い。In the present invention, the ring detent means comprises a convex portion and a concave portion which are fitted and locked to each other by press-fitting the ring portion into the shaft cylinder. Here, when the convex portion is formed on the inner surface side of the ring portion, the ring portion has a substantially saw-toothed cross section protruding in a direction opposite to the press-fitting mounting direction with respect to the shaft cylinder, and the outer surface side of the shaft tube. When it is formed in a rectangular shape, it is preferable to form it into a substantially saw-tooth shape in cross section projected in the press-fitting mounting direction. On the other hand, when the concave portion is formed on the inner surface side of the ring portion, the ring portion has a substantially saw-tooth cross-section recessed in the direction of press-fitting to the barrel, and when the concave portion is formed on the outer surface side of the barrel, the front portion is formed. It is preferable that the section is formed in a substantially saw-tooth shape in cross section which is recessed in a direction opposite to the press-fitting mounting direction. Incidentally, the ring detent means is not limited to the relationship between the convex part and the concave part. In other words, when the ring portion is press-fitted to the barrel, the load resistance should not be applied too much in the press-fitting mounting direction. Any shape and structure that can be firmly received so as not to rotate in the circumferential direction of the cylinder may be used.
【０００９】 又、リング回り止め手段としては、リング部を軸筒に圧入することにより同リ ング部とクリップ部とを連結する連結部の両連結片間の肉盗み部に挿入せしめた 状態で嵌合掛止する軸筒の外面に設けた突起部である。[0009] The ring detent means may be inserted into a stealth portion between two connecting pieces of a connecting portion connecting the ring portion and the clip portion by press-fitting the ring portion into the shaft cylinder. It is a projection provided on the outer surface of the shaft cylinder to be fitted and latched.
【００１０】 而して、斯かる技術的手段によれば、クリップ部はその幅よりも狭い間隔にて 設けた連結部の両側連結片によりリング部に連結されることで、リング部に対す る連結強度が向上される。又、連結部の両側連結片はクリップ部の厚さと略同じ ことから、成形時の引け問題は発生することが無い。 又、軸筒の装着部にリング部を圧入すると、該リング部は装着部に対して互い に嵌合掛止し合う凸部と凹部とによって装着部に周方向に回らないようにしっか りと受け止められた状態で装着される。 又、軸筒の装着部にリング部を圧入すると、該リング部とクリップ部とを連結 する連結部の両連結片間の肉盗み部に挿入せしめた状態で嵌合掛止する軸筒の外 面に設けた突起部によって装着部に周方向に回らないようにしっかりと受け止め られた状態で装着される。[0010] According to such technical means, the clip portion is connected to the ring portion by the both-side connecting pieces of the connecting portion provided at an interval smaller than the width thereof, so that the clip portion is connected to the ring portion. The connection strength is improved. Further, since the connecting pieces on both sides of the connecting portion are substantially the same as the thickness of the clip portion, no shrinkage problem occurs during molding. Also, when the ring portion is press-fitted into the mounting portion of the barrel, the ring portion is prevented from turning around the mounting portion in the circumferential direction by the convex portion and the concave portion which are fitted and latched to the mounting portion. It is attached while being received. Also, when the ring portion is press-fitted into the mounting portion of the shaft tube, the outer portion of the shaft tube that is fitted and latched in a state where the ring portion is inserted into the stealing portion between the two connecting pieces of the connecting portion connecting the ring portion and the clip portion. It is mounted in such a state that it is firmly received by the projections provided on the surface so that it does not rotate in the circumferential direction.
【００１１】[0011]
本考案の実施の具体例を図面に基づいて説明する。 図１は本考案筆記具の実施形態の一例を示した正面図で、１は軸筒、２は同じ くクリップであり、このクリップ１の後述するリング部2-2を軸筒１の後端側に 圧入することにより、クリップ２を軸筒１の後端側に嵌合装着し得るように構成 してある。 又、クリップ２のリング部2-2内面と、このリング部2-2が嵌合装着される軸筒 １の外面との間には軸筒１に対するリング部2-2の圧入取付方向に対して逆向き 方向のリング回り止め手段３を設けて、リング部2-2を軸筒１に圧入することに より、リング回り止め手段３の働きによりリング部2-2が軸筒１の周方向に回ら ないように構成してある。 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an example of an embodiment of the writing instrument according to the present invention. Reference numeral 1 denotes a barrel, and 2 denotes a clip. The clip 2 can be fitted to the rear end side of the barrel 1 by press-fitting. Also, between the inner surface of the ring portion 2-2 of the clip 2 and the outer surface of the barrel 1 to which the ring portion 2-2 is fitted, the press-fit mounting direction of the ring portion 2-2 with respect to the barrel 1 is provided. And the ring part 2-2 is press-fitted into the barrel 1 so that the ring part 2-2 is moved in the circumferential direction of the barrel 1. It is configured so that it does not turn around.
【００１２】 軸筒１、クリップ２は、適宜の合成樹脂材料を用いて一体成形してなる樹脂製 品である。The barrel 1 and the clip 2 are resin products integrally formed using an appropriate synthetic resin material.
【００１３】 因みに、本実施例の筆記具は軸筒１の内部にボールペン要素やシャープペンシ ル要素を組み込み内蔵してなる。例えば、軸筒１の後端から突出する操作部12の 例えばノック操作により、軸筒１の先端（ペン先）から筆記部が出没するタイプ のノック式ボールペンやノック繰出し式シャープペンシルである。Incidentally, the writing instrument of the present embodiment has a ball-point pen element and a mechanical pencil element incorporated inside the barrel 1. For example, there is a knock-type ballpoint pen or a knock-out type mechanical pencil in which a writing portion protrudes and retracts from the tip (pen tip) of the barrel 1 by, for example, a knocking operation of the operating section 12 protruding from the rear end of the barrel 1.
【００１４】 そして、軸筒１の後端側外面にはリング部2-2の内径と略同じ外径を有し且つ 同リング部2-2の筒長さに相当する装着部４を形成すると共に、装着部４に回り 止め手段３を構成する凹部3-1を形成してなる。A mounting portion 4 having substantially the same outer diameter as the inner diameter of the ring portion 2-2 and corresponding to the cylinder length of the ring portion 2-2 is formed on the outer surface of the rear end side of the barrel 1. At the same time, a concave portion 3-1 constituting the rotation stopping means 3 is formed in the mounting portion 4.
【００１５】 凹部3-1は、装着部４に対するリング部2-2の圧入取付方向に対して逆向き方向 に向けた傾斜部５と当該方向に対して直交する垂直部６からなる断面略鋸刃状に 装着部４の適宜の部位に形成され（図３参照）、リング部2-2が装着部４に圧入 されることで、該リング部2-2の後述する凸部3-2が嵌合掛止せしめるようになっ ている。 そして、凹部3-1は装着部４の周方向１乃至数カ所に形成される。この凹部3-1 を周方向１乃至数カ所に設けて、リング部2-2の凸部3-2が嵌合掛止するように形 成することにより、リング部2-2が周方向に回るのを防ぐ回り止め作用抜止作用 に加えてリング部2-2が筒方向に抜けるのを防ぐ抜止め作用をも発揮する（図２ 参照）。即ち、リング回り止め手段３は、装着部４に対するリング部2-2の抜止 めをも兼ね備える。The recess 3-1 has a substantially saw-shaped cross section including an inclined portion 5 directed in a direction opposite to a direction in which the ring portion 2-2 is press-fitted to the mounting portion 4 and a vertical portion 6 orthogonal to the direction. An appropriate portion of the mounting portion 4 is formed in a blade shape (see FIG. 3), and the ring portion 2-2 is press-fitted into the mounting portion 4 so that a convex portion 3-2 described later of the ring portion 2-2 is formed. It is designed to be fitted and latched. The recess 3-1 is formed at one or several places in the circumferential direction of the mounting part 4. The concave portion 3-1 is provided at one or several places in the circumferential direction, and the convex portion 3-2 of the ring portion 2-2 is formed so as to fit and lock, so that the ring portion 2-2 turns in the circumferential direction. In addition to the anti-rotation function that prevents the ring from coming off, it also exerts the anti-rotation function that prevents the ring portion 2-2 from coming off in the cylinder direction (see Fig. 2). That is, the ring rotation preventing means 3 also serves to prevent the ring portion 2-2 from being removed from the mounting portion 4.
【００１６】 クリップ２は、クリップ部2-1と、このクリップ部2-1を軸筒１の装着部４に取 付けるリング部2-2と、クリップ部2-1とリング部2-2とを連結する連結部2-3とか ら一体に構成されてなる。The clip 2 includes a clip part 2-1, a ring part 2-2 for attaching the clip part 2-1 to the mounting part 4 of the barrel 1, a clip part 2-1 and a ring part 2-2. And a connecting part 2-3 for connecting the two.
【００１７】 クリップ部2-1とリング部2-2とを連結する連結部2-3は、バネ性を発揮し得る ように所要の厚さの略板片状に成形されるクリップ部2-1の幅よりも狭い間隔に てクリップ部2-1とリング部2-2とを連結する両側の連結片７から形成してなる。 この連結片７の厚さはクリップ部2-1の厚さと略同じ程度の厚さにすることで 、肉厚の違いにより発生する成形時の引け問題が起らないようにしてなる。従っ て、両側の連結片７の間にはクリップ方向に貫通状に開口する肉盗み部８が存在 することになる（図２参照）。The connecting portion 2-3 for connecting the clip portion 2-1 and the ring portion 2-2 is formed into a substantially plate-like clip portion having a required thickness so as to exhibit spring characteristics. It is formed from connecting pieces 7 on both sides for connecting the clip part 2-1 and the ring part 2-2 at an interval smaller than the width of 1. By setting the thickness of the connecting piece 7 to be substantially the same as the thickness of the clip portion 2-1, a shrinkage problem during molding caused by a difference in wall thickness does not occur. Therefore, between the connecting pieces 7 on both sides, there is a stolen portion 8 that opens in a penetrating manner in the clip direction (see FIG. 2).
【００１８】 リング部2-2は、クリップ部2-1や連結部2-3の両連結片７と略同じ程度の厚さ にて成形され、その内面には前述の凹部3-1に嵌合掛止し合うリング回り止め手 段３を構成する凸部3-2が形成されている。The ring portion 2-2 is formed to have substantially the same thickness as the connecting pieces 7 of the clip portion 2-1 and the connecting portion 2-3. A convex portion 3-2 constituting the ring detent means 3 to be engaged with each other is formed.
【００１９】 凸部3-2は、リング部2-2を軸筒１の装着部４に、同装着部４基端の段部９に衝 合するまで圧入せしめた状態において、該装着部４の前述した凹部3-1に対応す るリング部2-2の内面部位に、該凹部3-1の突出形状（断面略鋸刃状）に適合する 同じく傾斜部10と垂直部11からなる断面略鋸刃形状に形成され（図３参照）、リ ング部2-2が装着部４に圧入されることで、凹部3-1に嵌合掛止せしめてリング部 2-2が装着部４の周方向に回らないように同装着部４に定着保持する。The convex portion 3-2 is fitted into the mounting portion 4 of the barrel 1 until the ring portion 2-2 is pressed into the mounting portion 4 of the barrel 1 until it abuts against the step 9 at the base end of the mounting portion 4. The inner surface of the ring portion 2-2 corresponding to the recess 3-1 described above is fitted with a protruding shape (substantially saw blade shape) of the recess 3-1. It is formed in a substantially saw blade shape (see FIG. 3), and the ring portion 2-2 is press-fitted into the mounting portion 4 so that the ring portion 2-2 is fitted and locked in the recess 3-1 so that the ring portion 2-2 is mounted. Is fixed to the mounting portion 4 so as not to rotate in the circumferential direction.
【００２０】 次に、以上の如く構成した本実施例筆記具の軸筒１に対するクリップ２の取り 付け方について簡単に説明すると、周囲数カ所（図では３ヶ所）に存在するリン グ回り止め手段３の凹部3-1と、凸部3-2とを軸方向に対応位置させ、その状態で クリップ２のリング部2-2を軸筒１の装着部４に圧入する。この時、装着部４の 外径と略同径な内径のリング部2-2は内面凸部3-2の傾斜部11によりガイドされる ことにより外側に押し広げられるように装着部４に対して基端の段部９に衝合さ れるまで嵌挿され、同時に内面の凸部3-2が装着部４の凹部3-1にリング部2-2の 反撥力（復元力）により落とし込まれるように嵌合掛止される。 従って、クリップ２のリング部2-2を軸筒１の装着部４に一旦圧入すると、リ ング部2-2はリング回り止め手段３の凹部3-1と凸部3-2との嵌合掛止により、周 方向の回り止めと抜止めが図られた状態で該装着部４に定着保持される。換言す れば、クリップ２を軸筒１にしっかりと定着保持させることができる。Next, the way of attaching the clip 2 to the barrel 1 of the writing instrument of the present embodiment configured as described above will be briefly described. The concave portions of the ring detent means 3 existing at several places (three places in the figure) are described. 3-1 and the convex portion 3-2 are positioned corresponding to each other in the axial direction. In this state, the ring portion 2-2 of the clip 2 is pressed into the mounting portion 4 of the barrel 1. At this time, the ring portion 2-2 having an inner diameter substantially the same as the outer diameter of the mounting portion 4 is guided by the inclined portion 11 of the inner convex portion 3-2 so that the ring portion 2-2 can be pushed outward so as to be spread outward. Until it abuts against the step 9 at the base end, and at the same time, the convex portion 3-2 on the inner surface is dropped into the concave portion 3-1 of the mounting portion 4 by the repulsive force (restoring force) of the ring portion 2-2. It is locked so that it fits. Therefore, once the ring part 2-2 of the clip 2 is press-fitted into the mounting part 4 of the barrel 1, the ring part 2-2 is fitted with the concave part 3-1 and the convex part 3-2 of the ring detent means 3. As a result, the attachment is fixed to the mounting portion 4 in a state where the rotation is prevented and the stopper is prevented in the circumferential direction. In other words, the clip 2 can be firmly fixed and held on the barrel 1.
【００２１】 尚、前述の実施例においてはリング回り止め手段３の凹部3-1を軸筒１の装着 部４に、凸部3-2をクリップ２のリング部2-2に夫々設けて、互いに嵌合掛止し合 うことによりクリップ２を軸筒１に定着保持するように詳述したが、凹部3-1を リング部2-2側に、凸部3-2を装着部４側に夫々設けてクリップ２を軸筒１に定着 保持させるように構成するも勿論良い。この場合には凹部3-1、凸部3-2をリング 部2-2の軸筒１に対する圧入取付方向に凹ませた又は突出させた断面略鋸刃状に 形成するものである。In the above-described embodiment, the concave portion 3-1 of the ring rotation preventing means 3 is provided on the mounting portion 4 of the barrel 1 and the convex portion 3-2 is provided on the ring portion 2-2 of the clip 2, respectively. It has been described in detail that the clip 2 is fixedly held on the barrel 1 by fitting and locking each other, but the concave portion 3-1 is on the ring portion 2-2 side, and the convex portion 3-2 is on the mounting portion 4 side. It is, of course, also possible to adopt a configuration in which the clips 2 are fixedly held on the barrel 1 by being provided respectively. In this case, the concave portion 3-1 and the convex portion 3-2 are formed in a substantially saw-tooth cross-section in which the ring portion 2-2 is depressed or protruded in the direction of press-fitting the shaft cylinder 1 with respect to the shaft cylinder 1.
【００２２】 図４乃至６は本考案筆記具の他の実施形態を示し、斯かる実施例ではクリップ ２のリング部2-2の周方向への回りを防ぐリング回り止め手段13の構成形態を変 えた以外においては前述した実施例詳述と基本的に変わりないことから同じ構成 部分に同じ符号を用いることでその説明を省略する。 即ち、斯かる実施例では軸筒１の後端側外面にリング部2-2の内径と略同じ外 径を有し且つ同リング部2-2の筒長さに相当する装着部14を、軸筒１の後端縁部 にリング抜止め部15を残した状態で形成する。4 to 6 show another embodiment of the writing instrument of the present invention. In this embodiment, the configuration of the ring rotation preventing means 13 for preventing the ring portion 2-2 of the clip 2 from rotating in the circumferential direction is changed. Except for the above, the description is basically omitted by using the same reference numerals for the same components since it is basically the same as the above-described detailed description of the embodiment. That is, in such an embodiment, the mounting portion 14 having substantially the same outer diameter as the inner diameter of the ring portion 2-2 and corresponding to the cylinder length of the ring portion 2-2 is provided on the outer surface of the rear end side of the shaft cylinder 1. It is formed with the ring retaining portion 15 left at the rear end of the barrel 1.
【００２３】 又、この装着部14基端の段部16側の軸筒１外面にはリング部2-2を圧入するこ とにより、このリング部2-2とクリップ部2-1とを連結する前述の連結部2-3の連 結片７間に存在する肉盗み部８に挿入せしめた状態で嵌合掛止せしめる突起部13 -1を設ける。 つまり、斯かる実施例においてはクリップ２側に設けた肉盗み部８に軸筒１側 に設けた突起部13-1が挿入せしめた状態で嵌合掛止せしめることによりリング部 2-2の回り止めを図るように形成してなる。The ring portion 2-2 is connected to the clip portion 2-1 by press-fitting the ring portion 2-2 into the outer surface of the barrel 1 on the step 16 side at the base end of the mounting portion 14. A projection 13-1 is provided to be fitted and latched while being inserted into the meat stealing portion 8 existing between the connecting pieces 7 of the connecting portion 2-3. That is, in this embodiment, the ring portion 2-2 is formed by engaging the protrusion 13-1 provided on the shaft cylinder 1 with the meat stealing portion 8 provided on the clip 2 side. It is formed so as to prevent rotation.
【００２４】 突起部13-1は、リング部2-2を軸筒１の装着部14に、同装着部14基端の段部16 に衝合するまで圧入せしめた状態において、両連結片７間の肉盗み部８に挿入す るように嵌合掛止せしめて装着部14の周方向に回らないように同装着部14にリン グ部2-2を定着保持する（図４及び図５参照）。The protruding portion 13-1 engages the two connecting pieces 7 in a state where the ring portion 2-2 is pressed into the mounting portion 14 of the barrel 1 until it abuts against the step 16 at the base end of the mounting portion 14. The ring portion 2-2 is fixedly held on the mounting portion 14 so as not to rotate in the circumferential direction of the mounting portion 14 by being fitted and hooked so as to be inserted into the meat stealing portion 8 between them (FIGS. 4 and 5). reference).

本考案の筆記具は叙上の如く構成してなることから下記の作用効果を奏する。 本考案によれば、クリップ部の幅よりも狭い間隔にて配設した両側の連結片か らなる連結部にてクリップ部とリング部を連結してなることで、クリップ部とリ ング部とを十二分の耐久強度を持たせた状態で連結することができる。即ち、従 来筆記具のクリップ部とリング部とを連結する厚さを有する連結部を、クリップ 部の幅内において適宜の間隔をおいて並設させたダブル連結構造にてクリップ部 とリング部とを連結することができる。 従って、連結部が繰り返し受ける応力により疲労することが無く、長期に亘り クリップ部をしっかりと安定良く連結保持すると言った品質の安定性が期待でき る。 Since the writing instrument of the present invention is configured as described above, it has the following effects. According to the present invention, the clip portion and the ring portion are connected to each other by connecting the clip portion and the ring portion by the connecting portion including the connecting pieces on both sides disposed at a smaller interval than the width of the clip portion. Can be connected in a state having sufficient durability strength. That is, the connecting portion having a thickness for connecting the clip portion and the ring portion of the conventional writing instrument has a double connecting structure in which the connecting portion having a thickness within the width of the clip portion is juxtaposed with the clip portion and the ring portion. Can be linked. Therefore, it is possible to expect a stable quality in which the clip portion is firmly and stably connected and held for a long time without fatigue due to the stress repeatedly applied to the connecting portion.
【００２８】 又、本考案によれば、クリップ部とリング部とを強靭に連結し得る間隔をおい て設けた両側の連結片の厚さをクリップ部の厚さと略同じく形成することができ る。即ち、連結片の厚さはクリップ部の厚さと略同じ程度の厚さにすることで、 肉厚の違いにより発生する成形時の引け問題は起らない。Further, according to the present invention, the thickness of the connecting pieces on both sides provided with an interval capable of strongly connecting the clip portion and the ring portion can be formed to be substantially the same as the thickness of the clip portion. . That is, by setting the thickness of the connecting piece to be substantially the same as the thickness of the clip portion, the shrinkage problem during molding caused by the difference in wall thickness does not occur.
【００２９】 又、本考案によれば、リング部と軸筒との間に設けるリング回り止め手段を周 方向１乃至数カ所において互いに嵌合掛止し合う凸部と凹部から構成し、尚且つ 、この凸部と凹部とをリング部の軸筒に対する圧入取付方向に対して逆向き方向 に突出させた又は凹ませた断面略鋸刃状に設けることで、クリップのリング部を 軸筒に対して回り止め作用のみならず、抜止め作用をも発揮せしめた状態で装着 することができることから、有効であると同時に、凸部と凹部とは外部に露出し ないことにより、筆記具の外観が損なうこともない。Further, according to the present invention, the ring detent means provided between the ring portion and the shaft cylinder is composed of a convex portion and a concave portion which are fitted and engaged with each other at one or several places in the circumferential direction. By providing the convex and concave portions in a substantially saw-toothed cross-section that is protruded or recessed in a direction opposite to the press-fitting mounting direction of the ring portion to the barrel, the ring portion of the clip is positioned relative to the barrel. It is effective because it can be attached while exerting not only the rotation preventing function but also the retaining function, so it is effective, and at the same time, the appearance of the writing implement is impaired by not exposing the convex and concave parts to the outside Nor.
【００３０】 又、本考案によれば、クリップのクリップ部とリング部を連結する連結部の両 連結片間に存在する肉盗み部に挿入せしめた状態で嵌合掛止する軸筒の外面に設 けた突起部によって軸筒に対するリング部の回り止めを図るように構成してなる ことで、突起部の存在はその表側に存在するクリップ部によって目隠しされた状 態となる。それにより、軸筒の外面に突出する突起部の存在は目視され難くなり 、筆記具の外観が損なわれることがない。Further, according to the present invention, the outer surface of the shaft cylinder that is fitted and latched in a state where it is inserted into the thin portion present between the two connecting pieces of the connecting portion that connects the clip portion and the ring portion of the clip. Since the ring portion is prevented from rotating with respect to the shaft cylinder by the provided projection portion, the presence of the projection portion is blinded by the clip portion present on the front side thereof. Thus, the presence of the protrusion projecting from the outer surface of the barrel becomes less visible, and the appearance of the writing instrument is not impaired.
