Description

本発明は、筆記具の軸筒もしくはキャップに取り付けられるクリップに関するものであり、更には金属線材で成形されたクリップに関するものである。   The present invention relates to a clip attached to a shaft cylinder or a cap of a writing instrument, and further relates to a clip formed of a metal wire.

筆記具のクリップは、筆記具を洋服のポケットに入れて携帯する場合などに必要な部品であり、また、意匠的にも重要な部品であるが、普及型の筆記具の場合は、そのクリップは合成樹脂にて軸筒もしくはキャップと一体に成形されることが多い。一方、高級筆記具の場合は、金属板で成形されたクリップが合成樹脂や金属で成形された軸筒もしくはキャップに取り付けられることが多い。   The clip of the writing instrument is a necessary part when carrying the writing instrument in the pocket of clothes, and it is also an important part of the design. In the case of a popular writing instrument, the clip is made of synthetic resin. In many cases, it is molded integrally with the shaft cylinder or cap. On the other hand, in the case of a high-grade writing instrument, a clip formed of a metal plate is often attached to a shaft cylinder or cap formed of synthetic resin or metal.

合成樹脂にて軸筒もしくはキャップと一体に成形されたクリップは、低コストで簡単に製造できるが、クリップ自体の弾発力がほとんどないために、筆記具を洋服のポケットなどに入れたときに、被挟圧物である布地などに対する圧接力が弱くて不安定である。また、合成樹脂製のクリップは高級感が出しにくく、意匠的にも問題がある。   Clips that are molded integrally with the shaft or cap with synthetic resin can be easily manufactured at low cost, but because the clip itself has little resilience, when writing instruments are put in clothes pockets, etc. The pressure of contact with the fabric being pressed is weak and unstable. In addition, the synthetic resin clip is difficult to produce a high-class feeling and has a design problem.

一方、金属板で成形されたクリップは、合成樹脂製のものに比べて布地などに対する圧接力が強く、高級感も出し易いが、クリップ自体の加工に手間を要する。また、強い圧接力が要求される場合は、弾発部材を介在させてその弾発力で布地などに圧接するが、部品点数が多くなり、組立作業が複雑になる不具合がある。   On the other hand, a clip formed of a metal plate has a strong pressure contact with a cloth or the like as compared with a synthetic resin, and it is easy to give a high-class feeling, but it takes time to process the clip itself. In addition, when a strong pressing force is required, a resilient member is interposed and pressed against the cloth or the like by the resilient force, but there is a problem that the number of parts increases and the assembling work becomes complicated.

このため、金属線材を屈曲して成形するクリップが一部で実用化されている。かかるクリップは外観形状がシンプルであって意匠上も好ましい。そして、金属製のクリップであるにもかかわらず簡単に成形できる利点を有する。しかし、金属線材をU字状に屈曲して成形されたクリップ本体部の尾端をほぼ直角に折り曲げて固定部とし、この固定部を軸筒やキャップに差し込んで固定するものは、布地などに対する圧接力が必ずしも十分ではなかった。
特開平11−321184公報
For this reason, some clips for bending and forming metal wires have been put to practical use. Such a clip has a simple appearance and is preferable in terms of design. And it has the advantage which can be shape | molded easily although it is a metal clip. However, the tail end of the clip body formed by bending a metal wire into a U-shape is bent at a substantially right angle to form a fixed portion, and this fixed portion is inserted into a shaft tube or a cap and fixed. The pressure contact force was not always sufficient.
Japanese Patent Laid-Open No. 11-32184

そこで本発明は、簡単に成形でき、外観形状がシンプルであって意匠上も好ましく、しかも布地などに対する圧接力が十分に大きな金属線材製のクリップを提供することを目的とする。   Accordingly, an object of the present invention is to provide a metal wire clip that can be easily formed, has a simple external shape, is favorable in design, and has a sufficiently large pressure contact force against a cloth or the like.

かかる目的を達成するために、本発明の筆記具用クリップは、弾性に富んだ金属線材をU字状に屈曲して成形され、先端部が軸筒もしくはキャップの表面に圧接するクリップ本体部と、このクリップ本体部の尾端からクリップ本体部に接するように先端側に屈曲された折り返し部と、この押し返し部の先端から略直角方向に伸びる固定部で構成し、固定部を軸筒もしくはキャップに差し込んで固定する。また、折り返し部は、クリップ本体部の尾端から円弧状屈曲部を介して折り返かえす。   In order to achieve such an object, the clip for a writing instrument of the present invention is formed by bending a metal wire rich in elasticity into a U-shape, and a tip body is pressed against the surface of a shaft tube or a cap; and It consists of a folded part bent to the tip side so that it comes into contact with the clip body part from the tail end of this clip body part, and a fixed part extending in a substantially right angle direction from the tip of this push-back part. Insert and fix. Further, the folded portion is folded back from the tail end of the clip main body portion via the arc-shaped bent portion.

金属線材を屈曲して成形するので、簡単に成形できて外観形状がシンプルであって意匠上も好ましいが、洋服のポケットなどに差し込んだときに、クリップ本体部が持ち上がり、クリップ本体部先端部の圧接部が軸筒やキャップの表面から離間するが、このとき、クリップ本体部の弾性変形に加えて、クリップ本体部と折り返し部との屈曲部分および折り返し部と固定部との屈曲部分の2箇所の屈曲部で弾性変形して弾発力が生じるので、布地などに対する圧接力が十分に大きくなる。また、折り返し部をクリップ本体部の尾端から円弧状屈曲部を介して折り返かえすと、円弧状屈曲部の線材は捩れてトーションバーの働きをするのでより強い圧接力を得ることができる。。   Since the metal wire is bent and molded, it can be easily molded, and the appearance is simple and the design is preferable, but when inserted into a pocket of clothes, the clip body rises and the clip body The press contact part is separated from the surface of the shaft cylinder and the cap. At this time, in addition to the elastic deformation of the clip main body part, the bent part of the clip main body part and the folded part and the bent part of the folded part and the fixing part Since elastic force is generated by elastic deformation at the bent portion, the pressing force against the fabric or the like becomes sufficiently large. Further, when the folded portion is folded back from the tail end of the clip main body portion via the arc-shaped bent portion, the wire rod of the arc-shaped bent portion is twisted and functions as a torsion bar, so that a stronger pressing force can be obtained. .

図1は本発明のクリップをボールペンの軸筒に取り付けた例を示すが、軸筒に限られるものでなくキャップであってもよい。図1において、合成樹脂で成形された前軸21の尾端部に中軸22の先端部が着脱自由に螺着されており、中軸22の尾端に後軸23が嵌着されている。そして、後述するクリップ10の固定部15がクッション部材24を介して中軸22と後軸23により挟圧保持されている。   Although FIG. 1 shows an example in which the clip of the present invention is attached to a shaft cylinder of a ballpoint pen, the cap is not limited to the shaft cylinder and may be a cap. In FIG. 1, a front end portion of a middle shaft 22 is detachably screwed to a tail end portion of a front shaft 21 formed of a synthetic resin, and a rear shaft 23 is fitted to the tail end of the middle shaft 22. A fixing portion 15 of the clip 10 to be described later is sandwiched and held by the middle shaft 22 and the rear shaft 23 via the cushion member 24.

前軸21、中軸22および後軸23で構成される軸筒内には、リターンスプリング32で尾端側に弾発されたボールペンレフィール31が前後動可能に収容されており、また、ボールペンレフィール31のペン体31aを前軸21の先端開口21aから出没させる機構が配置されている。この出没機構は、回転子33を使用する周知のダブルノック式の出没機構である。つまり、ボールペンレフィール31の尾端は回転子33に固定された詰め栓37に差し込まれており、復帰スプリング36で尾端側に弾発されたノックボタン35を押圧するとノック部材34が回転子33に回転力を付与した状態で前進させる。そして、回転子33が中軸22内面に形成された溝22aを抜け出すと回転子33は少し回転して係止段22bに係止し、ペン体31aが先端開口21aから突出して筆記可能になる。ペン体31aを先端開口21aから没入されるときもノックボタン35を押圧すればよく、これにより回転子33は少し回転して係止段22bとの係合が解除され、リターンスプリング32の弾発力により回転子33は溝22aに沿って後退するのでペン体31aは先端開口21aから没入する。   A ball pen refill 31 that is bounced back by a return spring 32 is accommodated in the shaft cylinder constituted by the front shaft 21, the middle shaft 22, and the rear shaft 23 so as to be movable back and forth. A mechanism for causing the pen body 31a to protrude from the tip opening 21a of the front shaft 21 is disposed. This in / out mechanism is a well-known double knock type in / out mechanism that uses the rotor 33. In other words, the tail end of the ballpoint pen refill 31 is inserted into a plug 37 fixed to the rotor 33, and when the knock button 35, which is ejected to the tail end side by the return spring 36, is pressed, the knock member 34 is moved to the rotor 33. Advancing in a state where rotational force is applied to. When the rotor 33 comes out of the groove 22a formed on the inner surface of the middle shaft 22, the rotor 33 is slightly rotated and locked to the locking step 22b, and the pen body 31a protrudes from the tip opening 21a and can be written. Even when the pen body 31a is inserted from the tip opening 21a, the knock button 35 may be pressed, whereby the rotor 33 is slightly rotated to disengage from the engaging step 22b, and the return spring 32 is released. Since the rotor 33 is retracted along the groove 22a by the force, the pen body 31a is immersed from the tip opening 21a.

クリップ10は、図2、図3に示すように、弾性に富んだ金属線材、例えば外径が1.0〜1.2mmφ程度のステンレス線材で成形されている。クリップ本体部11はこの線材でU字状に成形されており、その先端部は鈍角に折曲され、その頂点が軸筒の表面に圧接する圧接部12、12である。クリップ本体部11の尾端は2本の線材がそれぞれ先端とほぼ同じ曲率半径で円弧状に屈曲されて折り返し部13、13がクリップ本体部11に接するように先端側に折り返されている。この円弧状に屈曲された部分が円弧状屈曲部14である。なお、折り返し部13、13は必ずしも円弧状屈曲部14を介して折り返さなくてもよい。この折り返し部13、13は所定位置でほぼ直角に屈曲されて固定部15、15が続いており、その屈曲部がL字状屈曲部16である。そして、固定部15、15の先端部は円弧状になっている。この固定部15が図1に示すように軸筒に差し込まれ、前述のとおり、固定部15がクッション部材24を介して中軸22と後軸23により挟圧保持されている。   As shown in FIGS. 2 and 3, the clip 10 is formed of a metal wire rich in elasticity, for example, a stainless wire having an outer diameter of about 1.0 to 1.2 mmφ. The clip main body portion 11 is formed into a U shape with this wire, and the distal end portion thereof is bent at an obtuse angle, and the apexes thereof are press contact portions 12 and 12 that press against the surface of the shaft tube. The tail end of the clip main body 11 is folded back toward the front end so that the two wire rods are bent in an arc shape with substantially the same radius of curvature as the front end and the folded portions 13 and 13 are in contact with the clip main body 11. A portion bent in this arc shape is an arc-shaped bent portion 14. The folded portions 13 and 13 do not necessarily have to be folded through the arc-shaped bent portion 14. The folded portions 13 and 13 are bent at substantially right angles at predetermined positions, followed by fixing portions 15 and 15, and the bent portion is an L-shaped bent portion 16. And the front-end | tip part of the fixing | fixed parts 15 and 15 is circular arc shape. As shown in FIG. 1, the fixing portion 15 is inserted into the shaft tube, and as described above, the fixing portion 15 is held between the intermediate shaft 22 and the rear shaft 23 via the cushion member 24.

このように、このクリップ10は、金属線材を屈曲して成形するので、簡単に成形できて外観形状がシンプルであり、意匠上も好ましい。そして、洋服のポケットなどに差し込んだときに、クリップ本体部11が持ち上がり、圧接部12が軸筒やキャップの表面から離間する。このとき、クリップ本体部11も少し弾性変形して圧接力が生じるが、クリップ本体部11と折り返し部13との屈曲部分である円弧状屈曲部14および折り返し部13と固定部15との屈曲部分であるL字状屈曲部16が弾性変形してそれぞれの部分で弾発力が生じる。ことに円弧状屈曲部14は線材が捩れてトーションバーの働きをするので、布地などに対する圧接力が十分に大きくなる。   Thus, since this clip 10 is formed by bending a metal wire, it can be easily formed, has a simple external shape, and is preferable in terms of design. And when it inserts in the pocket etc. of clothes, the clip main-body part 11 lifts and the press-contact part 12 spaces apart from the surface of a shaft cylinder or a cap. At this time, the clip main body part 11 is also slightly elastically deformed to generate a pressure contact force, but the arcuate bent part 14 that is a bent part between the clip main body part 11 and the folded part 13 and the bent part between the folded part 13 and the fixing part 15. The L-shaped bent portion 16 is elastically deformed, and elastic force is generated at each portion. In particular, since the arc-shaped bent portion 14 functions as a torsion bar when the wire is twisted, the pressure contact force against the cloth or the like is sufficiently increased.
