(See Patent Document 1)
JP 2000-355185 A

しかしながら、上記した筆記具のグリップは、内方層と表面層の間に空間部がなく、手で把持した時に十分な弾性変形が得られなかった。
本発明は、上記課題を解消する筆記具のグリップを提供することを目的とするものである。 However, the grip of the writing instrument described above has no space between the inner layer and the surface layer, and sufficient elastic deformation cannot be obtained when gripped by hand.
An object of the present invention is to provide a grip for a writing instrument that solves the above-described problems.

本発明は、筆記具を把持する部分に取り付けられるグリップにおいて、そのグリップを、軟質材からなる内グリップと軟質材からなる外グリップの二層構造で構成し、前記内グリップの表面に突部を形成し、内グリップの表面と外グリップの内面の間に適宜の空間部を構成したことを第１の要旨とする。   The present invention relates to a grip attached to a portion for gripping a writing instrument, wherein the grip has a two-layer structure of an inner grip made of a soft material and an outer grip made of a soft material, and a protrusion is formed on the surface of the inner grip. The first gist is that an appropriate space is formed between the inner grip surface and the outer grip inner surface.

また、内グリップの表面に円周状に伸びた突部を複数形成し、内グリップの表面と外グリップの内面の間に適宜の空間部を構成したことを第２の要旨とする。   A second gist is that a plurality of circumferentially extending protrusions are formed on the surface of the inner grip, and an appropriate space is formed between the surface of the inner grip and the inner surface of the outer grip.

更に、内グリップの表面に多数の柱状の突部を形成し、内グリップの表面と外グリップの内面の間に適宜の空間部を構成したことを第３の要旨とする。   Furthermore, a third gist is that a number of columnar protrusions are formed on the surface of the inner grip, and an appropriate space is formed between the surface of the inner grip and the inner surface of the outer grip.

更にまた、内グリップの両端に外鍔を形成し、この２つの外鍔により内グリップを外グリップに嵌合したことを第４の要旨とする。   Furthermore, a fourth gist is that outer flanges are formed at both ends of the inner grip and the inner grip is fitted to the outer grip by the two outer flanges.

更にまた、外グリップを透明性を有した軟質材で構成したことを第５の要旨とする。   Furthermore, a fifth aspect is that the outer grip is made of a soft material having transparency.

本発明は、内グリップの表面に突部を形成して内グリップの表面と外グリップの内面の間に適宜の空間部を構成することにより、手で外グリップを把持した時に外グリップが十分に弾性変形をするので非常に把持し易い効果が奏せられるものである。   According to the present invention, a protrusion is formed on the surface of the inner grip, and an appropriate space is formed between the inner grip surface and the outer grip inner surface. Since it is elastically deformed, it is very easy to grip.

内グリップの表面と外グリップの内面との間に適宜の空間部を構成することにより、外グリップを把持した時に外グリップが弾性変形をして把持し易い筆記具のグリップを実現した。   By configuring an appropriate space between the inner grip surface and the inner surface of the outer grip, the grip of a writing instrument that is easy to grip due to elastic deformation of the outer grip when the outer grip is gripped is realized.

以下、図１及び図２に基づいて本発明における実施例１の筆記具のグリップを説明する。先ず、軟質材で作製された内グリップ１の表面に等間隔に多数の四角柱形の突部１Ａを形成する。また、内グリップ１の前端と後端に外鍔１Ｂを形成する。次に、軟質材で作製された外グリップ２の前端に内鍔２Ａを形成する。また、外グリップ２の外形は両端から中間部に向かって徐々に曲線状に細径に形成されている。この外グリップ２を前記内グリップ１に被せて筆記具のグリップを構成する。   Hereinafter, based on FIG.1 and FIG.2, the grip of the writing instrument of Example 1 in this invention is demonstrated. First, a large number of quadrangular prism-shaped protrusions 1A are formed at equal intervals on the surface of the inner grip 1 made of a soft material. Further, an outer collar 1B is formed at the front end and the rear end of the inner grip 1. Next, an inner collar 2A is formed at the front end of the outer grip 2 made of a soft material. Further, the outer shape of the outer grip 2 is gradually reduced in diameter from the both ends toward the middle portion. The outer grip 2 is put on the inner grip 1 to constitute a writing instrument grip.

次に、図３により本発明の筆記具のグリップをノック式シャープペンシルに設けた例で説明する。先ず、チャック３の頭部３Ａを複数に分割して拡開可能に形成し、この頭部３Ａにテーパー面を形成する。前記チャック３の頭部３Ａに締リング４を外嵌し、チャック３の後部にパイプ状の芯タンク５を圧入固着する。また、締リング４を受け止めるワッシャー６と芯タンク５の間にスプリング７を張架し、チャック３のテーパー面が締リング４に押圧され機構部が構成される。   Next, an example in which the grip of the writing instrument of the present invention is provided in a knock mechanical pencil will be described with reference to FIG. First, the head 3A of the chuck 3 is divided into a plurality of parts so as to be expanded, and a tapered surface is formed on the head 3A. A fastening ring 4 is externally fitted to the head 3A of the chuck 3, and a pipe-shaped core tank 5 is press-fitted and fixed to the rear part of the chuck 3. Further, a spring 7 is stretched between the washer 6 that receives the tightening ring 4 and the core tank 5, and the taper surface of the chuck 3 is pressed against the tightening ring 4 to constitute a mechanism portion.

軸筒８の前部８Ａは細径に形成され、この前部８Ａに前記内グリップ１を外嵌する。次に、内グリップ１に前記外グリップ２を外嵌する。すると、内グリップ１の外鍔１Ｂ及び突部１Ａが外グリップ２の内面に接触し、内グリップ１の表面と外グリップ２の内面の間に適宜の空間部が構成される。   A front portion 8A of the shaft cylinder 8 is formed with a small diameter, and the inner grip 1 is fitted on the front portion 8A. Next, the outer grip 2 is fitted on the inner grip 1. Then, the outer collar 1 </ b> B and the protrusion 1 </ b> A of the inner grip 1 come into contact with the inner surface of the outer grip 2, and an appropriate space is formed between the surface of the inner grip 1 and the inner surface of the outer grip 2.

この実施例１の場合には、突部１Ａが小さい程柔らかい感触となる。また、突部１Ａが高い程柔らかい感触となる。更に、突部１Ａの間隔が広い程柔らかい感触となる。   In the case of Example 1, the smaller the protrusion 1A, the softer the touch. Further, the higher the protrusion 1A, the softer the touch. Further, the wider the interval between the protrusions 1A, the softer the touch.

この軸筒８の前方より前記機構部を挿入した後、軸筒８に口金９を螺合し、口金９の内段９Ａと軸筒８の前端でワッシャー６を挟持する。また、口金９が螺合されることによって口金９の後端と軸筒８の外段８Ｂによって外グリップ２が挟持され、外グリップ２の内鍔２Ａと軸筒８の前部外段８Ｃにより内グリップ１が挟持される。   After the mechanism portion is inserted from the front side of the shaft tube 8, the base 9 is screwed into the shaft tube 8, and the washer 6 is sandwiched between the inner stage 9 </ b> A of the base 9 and the front end of the shaft tube 8. Further, when the base 9 is screwed together, the outer grip 2 is clamped by the rear end of the base 9 and the outer stage 8B of the shaft cylinder 8, and by the inner flange 2A of the outer grip 2 and the front outer stage 8C of the shaft cylinder 8. The inner grip 1 is clamped.

図４は本発明における実施例２の内グリップ１１を示したものである。内グリップ１１の表面に等間隔に円周方向に伸びた突部１１Ａを複数形成する。また、内グリップ１１の前端と後端に外鍔１１Ｂを形成する。この場合には、実施例１よりやや硬い感触が得られる。   FIG. 4 shows the inner grip 11 according to the second embodiment of the present invention. Plural protrusions 11A extending in the circumferential direction at equal intervals are formed on the surface of the inner grip 11. Further, an outer collar 11 </ b> B is formed at the front end and the rear end of the inner grip 11. In this case, a slightly harder feel than Example 1 can be obtained.

図５及び図６は本発明における実施例３の内グリップ２１を示したものである。内グリップ２１の上側半分の表面に長手方向に伸びた突部２１Ｃを等間隔に複数形成する。また、内グリップ２１の下側半分の表面に円周方向に伸びた突部２１Ｄを等間隔に複数形成する。この場合には下側がやや柔らかい感触となる。   5 and 6 show the inner grip 21 according to the third embodiment of the present invention. A plurality of protrusions 21C extending in the longitudinal direction are formed on the upper half surface of the inner grip 21 at equal intervals. In addition, a plurality of protrusions 21 </ b> D extending in the circumferential direction are formed at equal intervals on the lower half surface of the inner grip 21. In this case, the lower side has a slightly soft feel.

図７は本発明における実施例４の内グリップ３１を示したものである。内グリップ３１の上側半分の表面は極めて狭い等間隔で突部３１Ａを複数形成し、下側半分の表面は長手方向にやや広い等間隔で突部３１Ａを複数形成する。この場合には下側半分がやや柔らかい感触となる。   FIG. 7 shows an inner grip 31 according to the fourth embodiment of the present invention. The surface of the upper half of the inner grip 31 is formed with a plurality of protrusions 31A at evenly narrow intervals, and the surface of the lower half is formed with a plurality of protrusions 31A at slightly wider intervals in the longitudinal direction. In this case, the lower half has a slightly soft feel.

図８は本発明における実施例５の内グリップ４１を示したものである。内グリップ４１の表面に等間隔に円柱状の突部４１Ｅを多数形成する。尚、図示していないが、突部はその他半円形や円錐形等種々の形状が考えられる。   FIG. 8 shows an inner grip 41 according to the fifth embodiment of the present invention. A large number of cylindrical protrusions 41E are formed on the surface of the inner grip 41 at equal intervals. Although not shown, the protrusion may have various shapes such as a semicircular shape and a conical shape.

尚、上記実施例は、内グリップの突部が外グリップの内面に接触して構成されているが、内グリップの突部は必ずしも外グリップの内面に接触している必要はなく、隙間が設けられていても本発明の目的は十分に得られるものである。また、外グリップの外形は、中間部を太径にしたりあるいは単に円筒形にしたり、断面形状を三角形にしたり、肉厚を任意に変えたり等、種々の形状が考えられる。更に、本発明の内グリップは、等間隔に複数形成した突部の一部を模様や文字表示を表わすように突部を切り欠くことも可能である。   In the above embodiment, the protrusion of the inner grip is configured to be in contact with the inner surface of the outer grip, but the protrusion of the inner grip is not necessarily in contact with the inner surface of the outer grip, and a gap is provided. Even if it is, the objective of this invention is fully acquired. Also, the outer shape of the outer grip may be various shapes such as the middle portion having a large diameter, or simply a cylindrical shape, the cross-sectional shape being triangular, or the wall thickness being arbitrarily changed. Furthermore, in the inner grip of the present invention, it is possible to cut out the protrusions so that a part of the protrusions formed at equal intervals represents a pattern or character display.

更に、内グリップを着色した軟質材で形成するとともに、外グリップを透明な軟質材で形成すれば、内グリップの突部を模様として表わすことができる。また、外グリップを透明な軟質材で形成するとともに内グリップも透明な軟質材で形成すれば、軸筒が透けて見えるので新たな外観が表現できる。   Further, if the inner grip is formed of a colored soft material and the outer grip is formed of a transparent soft material, the protrusion of the inner grip can be represented as a pattern. Further, if the outer grip is formed of a transparent soft material and the inner grip is formed of a transparent soft material, a new appearance can be expressed because the shaft tube can be seen through.

更にまた、内グリップは、硬さ（ＪＩＳ Ａ）１０、３０あるいは５０といったシリコンラバーや、硬さ（ＪＩＳ Ａ）３０、５０あるいは７０といったエラストマーが考えられる。これらの内グリップと組み合わされる外グリップとしては、硬さ（ＪＩＳ Ａ）５０のシリコンラバーを用いることによって、種々の柔らかさのグリップが設定可能となる。   Furthermore, the inner grip may be a silicon rubber having a hardness (JIS A) 10, 30 or 50, or an elastomer having a hardness (JIS A) 30, 50 or 70. As the outer grip combined with these inner grips, various soft grips can be set by using silicon rubber having a hardness (JIS A) of 50.

更にまた、本発明の筆記具のグリップは、ノック式シャープペンシルに限定されるものではなく、ボールペン等種々の筆記具に利用できるものである。   Furthermore, the grip of the writing instrument of the present invention is not limited to a knock-type mechanical pencil, but can be used for various writing instruments such as a ballpoint pen.

筆記具のグリップの任意の箇所を任意の柔らかさに設定することができる。   Any part of the grip of the writing instrument can be set to any softness.
