Description

本発明は、筒状部材と頭端部材との間にクリップ基部を配し、前記頭端部材を前記筒状部材に対して回動することで、クリップ基部から筒状部材の側面に沿って垂設した挟持片を、筒状部材の側面に対して離間および接近させる構造の可動式クリップ付きの筆記具に関する。   According to the present invention, a clip base is disposed between the cylindrical member and the head end member, and the head end member is rotated with respect to the cylindrical member so that the clip base extends along the side surface of the cylindrical member. The present invention relates to a writing instrument with a movable clip having a structure in which a vertically sandwiched piece is separated from and approached to a side surface of a cylindrical member.

従来より、筆記具の軸筒本体やキャップ本体などの筒状部材の側面から突出させたクリップの挟持片を、必要に応じ、軸筒本体やキャップ本体などの筒状部材の側面に対して近づけることが可能である可動式クリップ付きの筆記具はよく知られている。例えば実開昭６３−１００２９０号公報には、軸胴と軸胴内に備えたガイド筒を相対的に回動することにより、内部に設けたカム機構がクリップ基部に作用し、クリップの挟持片が軸胴の側面に対して接近と離間を行える可動式クリップ構造が記載されている。   Conventionally, the holding piece of the clip protruding from the side surface of the cylindrical member such as the shaft cylinder body or cap body of the writing instrument is brought closer to the side surface of the cylindrical member such as the shaft cylinder body or cap body as necessary. Writing instruments with movable clips that are possible are well known. For example, in Japanese Utility Model Laid-Open No. 63-100200, a shaft cylinder and a guide cylinder provided in the shaft cylinder are relatively rotated so that an internal cam mechanism acts on a clip base, and a clip holding piece. Describes a movable clip structure that can move toward and away from the side of the barrel.

尚、一般的な可動式のクリップ構造では、筆記具の軸筒やキャップ本体などの筒状部材と頭冠や尾冠などの頭端部材との間にクリップ基部を配して装着してあることから、クリップを開いて胸ポケットの縁などの被挟持物を挟み込む場合には、頭端部材とクリップ基部とが擦れないことが好ましく、特に部材に金属を使用した場合には、双方が接触することによる接触音や接触摩耗が生じないようにすることが求められている。しかしながら従来の可動式クリップ構造では、クリップが筒状部材の軸心方向に対して直交する方向、つまりクリップの挟持片が、筒状部材の側面に対して近づくか離れるかの動作しか行うことができないことから、クリップ基部と頭端部材との間の隙間を広くして双方が接触しないようにするか、あるいはクリップの挟持片に軟らかい材質を用いたり、挟持片を弾性変形しやすい形状に設定するなどして、挟持片を持ち上げた際にクリップ基部が頭端部材に接触してしまわないように注意を払う必要があった。
「実開昭６３−１００２９０号公報」 In a general movable clip structure, a clip base is disposed between a cylindrical member such as a writing cylinder or a cap body and a head end member such as a head crown or a tail crown. From the above, when the clip is opened and the object to be clamped such as the edge of the breast pocket is sandwiched, it is preferable that the head end member and the clip base do not rub, particularly when metal is used for the member. Therefore, it is required to prevent contact noise and contact wear due to the occurrence of contact. However, in the conventional movable clip structure, only the operation in which the clip is perpendicular to the axial direction of the cylindrical member, that is, the clip clamping piece approaches or separates from the side surface of the cylindrical member. Because it is not possible, widen the gap between the clip base and the head end member so that they do not touch each other, or use a soft material for the clip holding piece, or set the holding piece to a shape that is easily elastically deformed Thus, it is necessary to pay attention so that the clip base does not come into contact with the head end member when the holding piece is lifted.
“Japanese Utility Model Publication No. 63-100200”

しかし、クリップ基部と頭端部材との間の隙間が常に広く開いていることは、見栄えが悪く、またクリップの挟持片の材質や形状に限定を与えてしまうことは、コスト面やデザイン面に影響を及ぼすという問題が生じていた。   However, if the gap between the clip base and the head end member is always wide, the appearance is bad, and limiting the material and shape of the clip clamping piece is a cost and design issue. There was a problem of influencing.

本発明はこうした問題を鑑みて、クリップの挟持片を筒状部材の側面に対して離間および接近させることが可能であると同時に、クリップ基部と頭端部材との間の隙間を狭め隙間が目立たない状態にすることや、クリップ基部と頭端部材との間の隙間を拡げることでクリップ基部と頭端部材とが接触しない状態にすることができる可動式クリップ付きの筆記具を提供することを目的とする。   In view of such a problem, the present invention makes it possible to separate and approach the clip holding piece with respect to the side surface of the cylindrical member, and at the same time, narrows the gap between the clip base and the head end member and makes the gap conspicuous. It is intended to provide a writing instrument with a movable clip that can be in a state in which the clip base and the head end member do not come into contact with each other by widening the gap between the clip base and the head end member. And

本発明の筒状部材とは、筆記具の軸筒やキャップ等の中空の筒状である部材のことをいい、頭端部材とは筒状部材の先端側にある頭冠のことだけでなく、後端側にあるいわゆる尾冠のことも含むものであり、要は筆記具の長手方向におけるクリップが装着してある側の端部にある部材のことをいう。また、クリップ基部に設けるカム部や該カム部に設ける凸部は、クリップ基部と一体に形成しても別体で設けてもよく、特にクリップ基部および挟持片を金属で形成する場合には、複雑形状であるカム部や凸部を設ける時の成形のしやすさや頭端部材の傾斜面との摺動性のよさから、樹脂材により別体で成形した方がよい。 尚、カム部をクリップ基部と別体で設ける場合には、筒状部材の軸心方向に直交する方向に対しては、クリップ基部とカム部とが頭端部材のカム受面により従動する構造とすると共に、カム部をクリップ基部と別体であるカム体に設ける場合には、頭端部材と筒状部材とを連結する連結軸がカム体にも挿通できるように、クリップ基部に設ける長孔状の貫通孔と同様に、カム体にも長孔状の貫通孔を設ける必要がある。また、クリップ基部やカム体に設ける貫通孔を、一端側から他端側の方向に長手を有した長孔状とするのは、軸心となる連結軸に対し、クリップ基部とカム体とを一端側方向と他端側方向に往復動可能とさせる隙間を設けるためである。   The cylindrical member of the present invention refers to a member having a hollow cylindrical shape such as a shaft tube or a cap of a writing instrument, and the head end member is not only a head crown on the distal end side of the cylindrical member, It also includes a so-called tail crown on the rear end side, and the main point is a member at the end on the side where the clip in the longitudinal direction of the writing instrument is attached. In addition, the cam portion provided on the clip base and the convex portion provided on the cam portion may be formed integrally with the clip base or separately, particularly when the clip base and the clamping piece are formed of metal, From the viewpoint of ease of molding when providing a cam part or a convex part having a complicated shape and good sliding property with the inclined surface of the head end member, it is better to mold the resin part separately. When the cam part is provided separately from the clip base part, the clip base part and the cam part are driven by the cam receiving surface of the head end member in the direction perpendicular to the axial direction of the cylindrical member. In addition, when the cam portion is provided in the cam body that is separate from the clip base, the length provided in the clip base so that the connecting shaft that connects the head end member and the tubular member can be inserted into the cam body. Like the hole-shaped through hole, the cam body must be provided with a long hole-shaped through hole. In addition, the through hole provided in the clip base and the cam body is in the shape of a long hole having a length in the direction from the one end side to the other end side. This is to provide a gap that enables reciprocation in the one end side direction and the other end side direction.

前述の通り本発明の可動式クリップ付きの筆記具は、頭端部材を回動することにより、クリップの挟持片を筒状部材の側面に対しては接近および離間させることができ、クリップの挟持片が筒状部材の側面から離間した状態では、クリップ基部と頭端部材との間の隙間が拡がり、挟持片で物を挟む際に、持ち上げたクリップのクリップ基部が頭端部材に直接接触してしまうことを防止できる。また、クリップの挟持片が筒状部材の側面に接近した状態では、クリップ基部と筒状部材との間の隙間が狭まり見栄えが良くなる。   As described above, the writing instrument with a movable clip according to the present invention can move the clip end piece toward and away from the side surface of the cylindrical member by rotating the head end member. However, in the state of being separated from the side surface of the cylindrical member, the gap between the clip base and the head end member is widened, and the clip base of the lifted clip comes into direct contact with the head end member when an object is sandwiched between the clamping pieces. Can be prevented. In addition, in a state where the clip holding piece approaches the side surface of the cylindrical member, the gap between the clip base and the cylindrical member is narrowed and the appearance is improved.

２項に係る発明では、クリップ基部とカム体とを別体とすることで、カム体にカム面を円弧状に形成したり凸部を形成する場合においても、カム体を樹脂材により射出成形して成形を容易とすることが可能になる。またクリップ基部が頭端部材でなくカム体に当接する構造なので、クリップ基部を有するクリップ本体に金属を採用した場合においても、カム体を樹脂で成形することにより、双方の接触が滑らかなものとなる。   In the invention according to item 2, by separating the clip base and the cam body, the cam body is injection molded with a resin material even when the cam surface is formed in an arc shape or a convex portion on the cam body. Thus, the molding can be facilitated. In addition, since the clip base is in contact with the cam body instead of the head end member, even when metal is adopted for the clip body having the clip base, both contacts can be made smooth by molding the cam body with resin. Become.

３項に係る発明では、さらにカム体とピン部材を別体とすることで、頭端部材を金属で形成した場合においても、ピン部材を樹脂材により射出成形することで、クリップ基部の一端側の上面とピン部材の下端部との接触、および頭端部材に設けた傾斜面とピン部材の上端部との接触が滑らかなものとなる。またさらに前述のように、クリップ基部や頭端部材を金属で形成した場合には、経時的にはピン部材が接触摩耗することとなるが、摩耗したピン部材だけを交換して性能を維持させることができる。   In the invention according to Item 3, by further separating the cam body and the pin member, even when the head end member is made of metal, the pin member is injection-molded with a resin material, so that one end side of the clip base portion The contact between the upper surface of the pin member and the lower end portion of the pin member, and the contact between the inclined surface provided on the head end member and the upper end portion of the pin member becomes smooth. Further, as described above, when the clip base and the head end member are made of metal, the pin member will be contacted and worn over time, but only the worn pin member is replaced to maintain the performance. be able to.

４項に係る発明では、カム部の上部に形成した突部が、頭端部材に形成した傾斜面に設けた係止凹部に係止できる構造とすることにより、使用者が頭端部材を回動させた際に、凸部が係止凹部に係止した時の感触によりクリップの状態を明確に認識することができるものとなる。   In the invention according to item 4, the protrusion formed on the upper portion of the cam portion can be locked to the locking recess provided on the inclined surface formed on the head end member, so that the user can rotate the head end member. When moved, the state of the clip can be clearly recognized by the touch when the convex portion is engaged with the engaging concave portion.

筒状部材の側面に対するクリップの挟持片の軸心に直交する方向の変位と同時に、頭端部材に対するクリップ基部の軸心に沿った方向の変位を可能とする構造の可動式クリップ構造を実現した。   Realized a movable clip structure with a structure that allows displacement in the direction along the axis of the clip base relative to the head end member simultaneously with displacement in the direction perpendicular to the axis of the clip clamping piece relative to the side surface of the cylindrical member .

次に、図２に示したように、クリップ本体４０の挟持片４ｂが、キャップ本体２の側面２０から離間する時の内部機構について図１１〜図１５を用いて詳述を行う。
図１１は図２の状態におけるキャップの縦断面図で、図１２は図１１の要部拡大図で、図１３はクリップと内筒との関係を解りやすくした状態の図である。図１４は図２の状態における頭冠をキャップ本体から外した時の平面視で、頭冠の内部構造を概念的に破線で示してある。図１５は図２の状態における頭冠を中間部で横断した断面図である。
本実施例の筆記具用キャップ１は、図１５に示すように、頭冠３を図１の状態から右回りに回動（図１における矢印Ａ方向）することにより、頭冠３の内側面に形成したカム受面３ｆが連結軸６を回転軸にして回動し、カム受面３ｆの第二肉厚部３ｉが第一カム体８の第一カム面８ｄを一方側方向に押して、第二カム体９の第二カム面９ｃをカム受面３ｆの第二肉薄部３ｊ側に寄せると共に、図１２に示すように、クリップ本体４０の挟持片４ｂをキャップ本体２の側面２０から離間させる構造である。この時図１２に示すように、凸部となったピン部材１０の上端部１０ａは、頭冠３の傾斜面３ｃにおける最浅部３ｅの係止凹部３０ｅに係止すると共に、下方に押し下げられ、押し下げられたピン部材１０の下端部１０ｂにより、コイルスプリング７で上方へ弾発されているクリップ基部４ａを下方に変位させて、クリップ基部４ａと頭冠３の下端部との間を拡げて、隙間Ｓを形成する。したがって、図１６に示すように、クリップ４の挟持片４ｂを開く際においては、頭冠３の傾斜面３ｃの係止凹部３０ｅに係止したピン部材１０の上端部１０ａが凸部として支点となり、隙間Ｓが狭まることで、クリップ基部４ｂを頭冠３の下端部に接触させることなく、挟持片４ｂを持ち上げることができた。
また反対に、図２に示すキャップ１の頭冠３を左回りに９０度回動（矢印Ｂ方向）させることにより、クリップ本体４０の挟持片４ｂは図１の状態となる。 Next, as shown in FIG. 2, the internal mechanism when the clamping piece 4 b of the clip body 40 is separated from the side surface 20 of the cap body 2 will be described in detail with reference to FIGS. 11 to 15.
FIG. 11 is a longitudinal sectional view of the cap in the state of FIG. 2, FIG. 12 is an enlarged view of the main part of FIG. 11, and FIG. 13 is a view of the state in which the relationship between the clip and the inner cylinder is easily understood. FIG. 14 is a plan view when the crown is removed from the cap body in the state of FIG. 2, and the internal structure of the crown is conceptually indicated by a broken line. 15 is a cross-sectional view of the head crown in the state shown in FIG.
As shown in FIG. 15, the writing instrument cap 1 according to the present embodiment rotates the head crown 3 clockwise from the state of FIG. 1 (in the direction of arrow A in FIG. 1), thereby The formed cam receiving surface 3f rotates about the connecting shaft 6 as a rotation axis, and the second thick portion 3i of the cam receiving surface 3f pushes the first cam surface 8d of the first cam body 8 in one direction, The second cam surface 9c of the two cam body 9 is brought closer to the second thin portion 3j side of the cam receiving surface 3f, and the clamping piece 4b of the clip body 40 is separated from the side surface 20 of the cap body 2 as shown in FIG. Structure. At this time, as shown in FIG. 12, the upper end portion 10 a of the pin member 10, which is a convex portion, is locked to the locking recess 30 e of the shallowest portion 3 e on the inclined surface 3 c of the crown 3 and is pushed downward. The clip base 4a, which is springed upward by the coil spring 7, is displaced downward by the lower end 10b of the pin member 10 that has been pushed down, and the space between the clip base 4a and the lower end of the crown 3 is expanded. A gap S is formed. Therefore, as shown in FIG. 16, when the clamping piece 4b of the clip 4 is opened, the upper end portion 10a of the pin member 10 locked to the locking recess 30e of the inclined surface 3c of the head crown 3 serves as a fulcrum. By narrowing the gap S, the clip piece 4b could be lifted without bringing the clip base 4b into contact with the lower end of the head crown 3.
On the other hand, when the head crown 3 of the cap 1 shown in FIG. 2 is rotated 90 degrees counterclockwise (in the direction of arrow B), the clamping piece 4b of the clip body 40 is in the state shown in FIG.

尚、本実施例では、クリップ本体４０および頭冠３を金属で形成してあるが、ピン部材１０は樹脂成形してあり、またピン部材１０の上端部１０ａおよび下端部１０ｂの先端を半球状に丸めてあることから、ピン部材１０の下端部１０ｂに当接しているクリップ基部４ｂおよびピン部材１０の上端部１０ａに当接している頭冠３の傾斜面３ｃは、滑らかに摺動することができた。   In this embodiment, the clip body 40 and the crown 3 are made of metal. However, the pin member 10 is resin-molded, and the tips of the upper end portion 10a and the lower end portion 10b of the pin member 10 are hemispherical. Therefore, the clip base 4b in contact with the lower end 10b of the pin member 10 and the inclined surface 3c of the head crown 3 in contact with the upper end 10a of the pin member 10 slide smoothly. I was able to.

また本実施例では、第二カム体９に形成した扇形の突起９ｆを、頭冠３の内天面に形成した略扇形の溝部３ｋ内に配してあり（図４，図９参照）、図１４に示すように、クリップ本体４０の挟持片４ｂをキャップ本体２の側面２０から離間させる方向に頭冠３を回動（図１における矢印Ａ方向）させた場合には、溝部３ｋの側縁３１ｋが突起９ｆに当接するまで頭冠３が回動し、図９に示すように、クリップ本体４０の挟持片４ｂをキャプ本体２の側面２０に接近させる場合には、溝部３ｋの側縁３２ｋが突起９ｆに当接するまで頭冠３が回動するので、使用者が頭冠３を回し過ぎることはない。   In the present embodiment, the fan-shaped protrusion 9f formed on the second cam body 9 is disposed in a substantially fan-shaped groove 3k formed on the inner top surface of the head crown 3 (see FIGS. 4 and 9). As shown in FIG. 14, when the crown 3 is rotated (in the direction of arrow A in FIG. 1) in a direction in which the clamping piece 4b of the clip body 40 is separated from the side surface 20 of the cap body 2, the groove 3k side The crown 3 is rotated until the edge 31k contacts the projection 9f, and when the clamping piece 4b of the clip body 40 is brought close to the side surface 20 of the cap body 2 as shown in FIG. 9, the side edge of the groove 3k. Since the crown 3 rotates until 32k comes into contact with the protrusion 9f, the user does not turn the crown 3 too much.

本発明による可動式クリップ構造は筆記具以外にも、化粧具や塗布具等のクリップ構造に用いることが可能である。   The movable clip structure according to the present invention can be used for a clip structure such as a cosmetic tool and an applicator in addition to a writing instrument.
