Description

この発明は、筆記具の正しい持ち方を習得するために使用できる筆記具用補助具及び筆記具に関する。   The present invention relates to a writing instrument auxiliary tool and a writing instrument that can be used to learn how to properly hold a writing instrument.

従来、筆記具の正しい持ち方を習得するための種々の用具が提案されている。   Conventionally, various tools for learning how to hold a writing instrument correctly have been proposed.

例えば鉛筆の軸部に渦巻状の溝を設けたもの（いわゆる「うずまき鉛筆」）が知られている。この種の鉛筆では、渦巻状の溝に指を合わせて持つことで鉛筆の持ち方を矯正する効果があるとされている。   For example, a pencil having a spiral groove on a shaft (so-called “spiral pencil”) is known. This kind of pencil is said to have an effect of correcting how to hold the pencil by holding the finger in a spiral groove.

また、特許文献１及び特許文献２には、鉛筆の周囲に弾性部材でできた矯正具を取り付けたものが記載されている。この種の矯正具は、指の位置に凹部などが設けられており、この凹部に指を合わせて鉛筆を持つことで正しい持ち方を習得できるとされている。   Patent Document 1 and Patent Document 2 describe one in which a correction tool made of an elastic member is attached around a pencil. This type of correction tool is provided with a recess or the like at the position of the finger, and it is said that the correct holding method can be learned by holding the pencil with the finger in the recess.

しかしながら、上記したような従来の矯正具は、鉛筆の正しい持ち方を習得するという目的だけに使用されるものであり、使用目的が限定されていた。
そこで、本発明は、単に筆記具の正しい持ち方を習得できるだけではなく、別の機能を付加した筆記具用補助具を提供することを課題とする。 However, the conventional correction tools as described above are used only for the purpose of learning how to hold a pencil correctly, and the purpose of use is limited.
Therefore, an object of the present invention is to provide an auxiliary tool for a writing instrument that not only learns how to properly hold a writing instrument but also has other functions.

本発明は、上記した課題を解決するためになされたものであり、以下を特徴とする。   The present invention has been made to solve the above-described problems, and is characterized by the following.

請求項１記載の発明は、筆記具を挿通可能な内筒と、前記内筒の外周に取り付けられる外筒と、を備え、前記内筒を前記外筒にねじ込むことで前記内筒の先端部が縮径して筆記具を保持する筆記具用補助具であって、前記外筒の外周には、筆記具を持つ指の位置に凹部が貫通形成され、前記凹部は、前記凹部に合わせた指の腹が接触するように、前記外筒に挿入した前記内筒を露出させることを特徴とする。 The invention according to claim 1 includes an inner cylinder through which the writing instrument can be inserted, and an outer cylinder attached to the outer periphery of the inner cylinder , and the distal end portion of the inner cylinder is screwed into the outer cylinder. a reduced diameter for a writing instrument aid for holding the writing instrument, the outer periphery of the outer cylinder, the recess at the position of the finger with the writing instrument formed through the recess, the ball of a finger to match the recess The inner cylinder inserted into the outer cylinder is exposed so as to come into contact .

請求項２に記載の発明は、上記した請求項１に記載の発明の特徴点に加え、筆記具を持つ人差し指の基節部に引っ掛け可能なフックを備え、前記フックは、人差し指の基節部に引っ掛けるためにペン先側が凹むように湾曲するアーム部を備えることを特徴とする。 The invention according to claim 2 is provided with a hook that can be hooked to the proximal portion of the index finger having a writing instrument, in addition to the feature of the invention according to claim 1, and the hook is attached to the proximal portion of the index finger. It is characterized by comprising an arm portion that curves so that the pen tip side is recessed for hooking .

請求項３に記載の発明は、削る必要のない軸部を備えた筆記具であって、前記軸部に請求項１又は２記載の筆記具用補助具を取り付けたことを特徴とする。   The invention described in claim 3 is a writing instrument provided with a shaft portion that does not need to be cut, and is characterized in that the writing tool auxiliary tool according to claim 1 or 2 is attached to the shaft portion.

請求項１に記載の発明は上記の通りであり、筆記具を挿通可能な内筒と、前記内筒の外周に取り付けられる外筒と、を備え、前記内筒を前記外筒にねじ込むことで前記内筒が縮径して筆記具を保持する筆記具用補助具である。すなわち、本発明に係る筆記具用補助具は、短くなった鉛筆を使用するための補助具として使用することができる。具体的には、筆記具用補助具を鉛筆に取り付けることで軸部を延長することができ、短くなって持ちにくくなった鉛筆であっても使用することができる。そして、前記外筒の外周には、筆記具を持つ指の位置に凹部が形成されているため、この凹部に指を合わせて筆記具を持つことで正しい持ち方を習得することができる。このように、本発明に係る筆記具用補助具を使用すれば、単に筆記具の正しい持ち方を習得できるだけではなく、補助軸としても使うことができる。   The invention according to claim 1 is as described above, and includes an inner cylinder through which a writing instrument can be inserted, and an outer cylinder attached to an outer periphery of the inner cylinder, and by screwing the inner cylinder into the outer cylinder, This is an auxiliary tool for writing instruments in which the inner cylinder is reduced in diameter and holds the writing instrument. That is, the writing instrument auxiliary tool according to the present invention can be used as an auxiliary tool for using a shortened pencil. Specifically, the shaft portion can be extended by attaching the writing instrument auxiliary tool to the pencil, and even a pencil that has become shorter and difficult to hold can be used. And since the recessed part is formed in the outer periphery of the said outer cylinder in the position of the finger | toe with a writing instrument, the correct holding method can be learned by holding a writing instrument with a finger | toe in this recessed part. Thus, if the writing instrument auxiliary tool according to the present invention is used, it can be used not only to learn the correct way of holding the writing instrument but also as an auxiliary shaft.

また、内筒を外筒にねじ込むことで筆記具を保持する構造であるため、様々な筆記具の太さに対応することができ、着脱も容易である。   Further, since the writing instrument is held by screwing the inner cylinder into the outer cylinder, it is possible to cope with the thickness of various writing instruments and it is easy to attach and detach.

また、請求項２に記載の発明は上記の通りであり、筆記具を持つ人差し指の基節部に引っ掛け可能なフックを備えるので、筆記具の傾きなどを正しい姿勢に保つことができる。このフックによって、更に正しい持ち方となるように促すことができる。   In addition, the invention according to claim 2 is as described above, and includes a hook that can be hooked on the proximal portion of the index finger having a writing instrument, so that the inclination of the writing instrument can be maintained in a correct posture. By this hook, it can be urged to become a more correct way of holding.

また、請求項３に記載の発明は上記の通りであり、削る必要のない軸部を備えた筆記具（ボールペンやシャープペンなど）に筆記具用補助具を取り付けている。すなわち、従来は補助軸が不要であったボールペンやシャープペンに補助軸を取り付けている。このような新しい発想は、「ボールペンやシャープペンを使用する大人が、まずは筆記具の正しい持ち方を習得すべきである」という考えに基づいている。   The invention according to claim 3 is as described above, and the writing tool auxiliary tool is attached to a writing tool (such as a ballpoint pen or a mechanical pencil) having a shaft portion that does not need to be cut. That is, the auxiliary shaft is attached to a ballpoint pen or a mechanical pen that conventionally does not require the auxiliary shaft. This new idea is based on the idea that “adults using ballpoint pens and mechanical pens should first learn how to hold the writing instrument correctly”.

すなわち、子供に筆記具の正しい持ち方を教える前に、まずは筆記具用補助具を取り付けたボールペンやシャープペンを大人が使用して筆記具の正しい持ち方を習得する。そして、大人が筆記具の正しい持ち方を習得したら、筆記具用補助具を取り外して子供に与える。この筆記具用補助具は鉛筆にも同じものを使用することができるので、子供は筆記具用補助具を鉛筆に取り付けて、補助軸として使用するとともに、正しい持ち方を練習する。このとき、大人はすでに筆記具用補助具を使用しているので、その経験を生かして大人が子供を指導することができる。このような構成によれば、そもそも親が鉛筆の正しい持ち方を知らず、どう教えて良いか分からない、といった問題を解消することができる。   That is, before teaching children how to properly hold writing instruments, adults first use ballpoint pens and mechanical pencils with writing instrument aids to learn how to properly hold writing instruments. When the adult learns how to properly hold the writing instrument, remove the writing instrument aid and give it to the child. The same writing instrument aid can be used for the pencil, so the child attaches the writing instrument aid to the pencil and uses it as an auxiliary shaft, and also practice how to hold it correctly. At this time, since adults are already using writing instrument aids, adults can use their experience to guide their children. According to such a configuration, it is possible to solve the problem that the parent does not know how to hold the pencil in the first place and does not know how to teach it.

A male screw portion 15 is provided on a part of the outer periphery of the insertion tube portion 14 and is screwed into a screw portion (not shown) since it is provided on the inner periphery of the outer tube 20. When the inner cylinder 11 is rotated relative to the outer cylinder 20, the male screw portion 15 and the female screw portion are engaged with each other so that the inner cylinder 11 can be screwed into the outer cylinder 20 or the inner cylinder 11 can be loosened from the outer cylinder 20. It is like that.

また、この挿入筒部１４の挿入側の先端部には、筆記具４０を保持するための保持部１６が設けられている。保持部１６には、周方向に所定間隔でスリット１６ｃが形成されており、このスリット１６ｃが形成されることによって複数の突出片１６ａが設けられている。これらの突出片１６ａの先端付近には、外周方向に突出する凸部１６ｂが形成されており、凸部１６ｂが形成されることで矢尻状となっている。内筒１１を外筒２０にねじ込むと、この凸部１６ｂが外筒２０の縮径部２１（後述）によって内側に押し込まれ、複数の突出片１６ａが内側に窄まることで筆記具４０を保持するようになっている。   A holding portion 16 for holding the writing instrument 40 is provided at the distal end portion on the insertion side of the insertion tube portion 14. Slits 16c are formed in the holding portion 16 at predetermined intervals in the circumferential direction, and a plurality of protruding pieces 16a are provided by forming the slits 16c. Protrusions 16b projecting in the outer peripheral direction are formed in the vicinity of the tips of these projecting pieces 16a, and the projecting parts 16b are formed to have an arrowhead shape. When the inner cylinder 11 is screwed into the outer cylinder 20, the convex portion 16b is pushed inward by a reduced diameter portion 21 (described later) of the outer cylinder 20, and the plurality of projecting pieces 16a are held inward to hold the writing instrument 40. It is like that.

外筒２０は、上記した内筒１１の外周に取り付けられる筒状部材である。この外筒２０は、内筒１１を挿通可能な内周面を有している。この内周面の一部には、内周面が徐々に先窄まりとなる縮径部２１が設けられている。この縮径部２１は、内筒１１を挿入したときに、内筒１１の保持部１６が臨む位置に設けられている。この縮径部２１を設けることで、内筒１１を外筒２０にねじ込んだときに、内筒１１の保持部１６（複数の突出片１６ａ）が内側に弾性変形して筆記具４０を保持できるようになっている。   The outer cylinder 20 is a cylindrical member attached to the outer periphery of the inner cylinder 11 described above. The outer cylinder 20 has an inner peripheral surface through which the inner cylinder 11 can be inserted. A part of the inner peripheral surface is provided with a reduced diameter portion 21 in which the inner peripheral surface is gradually tapered. The reduced diameter portion 21 is provided at a position where the holding portion 16 of the inner cylinder 11 faces when the inner cylinder 11 is inserted. By providing the reduced diameter portion 21, when the inner cylinder 11 is screwed into the outer cylinder 20, the holding portion 16 (the plurality of protruding pieces 16 a) of the inner cylinder 11 can be elastically deformed inward to hold the writing instrument 40. It has become.

また、この外筒２０の外周には、筆記具４０を持つ指の位置に凹部が形成されている。本実施形態においては、第１凹部２２と、第２凹部２３と、第３凹部２４と、の計３つの凹部が貫通形成されている。第１凹部２２は、筆記具４０を持つ親指の位置に形成されており、この第１凹部２２に親指の腹を合わせることで筆記具４０を正しく持てるようになっている。また、第２凹部２３は、筆記具４０を持つ人指し指の位置に形成されており、この第２凹部２３に人指し指の腹を合わせることで筆記具４０を正しく持てるようになっている。また、第３凹部２４は、筆記具４０を持つ中指の位置に形成されており、この第３凹部２４に中指の爪の根元を合わせることで筆記具４０を正しく持てるようになっている。   Further, a concave portion is formed on the outer periphery of the outer cylinder 20 at the position of the finger holding the writing instrument 40. In the present embodiment, a total of three recesses, a first recess 22, a second recess 23, and a third recess 24, are formed through. The first recess 22 is formed at the position of the thumb having the writing instrument 40, and the writing instrument 40 can be correctly held by aligning the belly of the thumb with the first recess 22. Moreover, the 2nd recessed part 23 is formed in the position of the index finger with the writing tool 40, and the writing tool 40 can be correctly held by aligning the belly of the index finger with this 2nd recessed part 23. FIG. The third recess 24 is formed at the position of the middle finger having the writing tool 40, and the writing tool 40 can be correctly held by aligning the base of the nail of the middle finger with the third recess 24.

フック３０は、外筒２０の外周部に取り付けられる部材であり、筆記具４０を持つ人差し指の基節部に引っ掛けて使用される。本実施形態に係るフック３０は金属製であり、外筒２０の外周を狭持するための略Ｃ字形の狭持片３１と、この狭持片３１から舌状に延出するアーム部３２と、を備える。   The hook 30 is a member attached to the outer peripheral portion of the outer cylinder 20 and is used by being hooked on the proximal portion of the index finger having the writing instrument 40. The hook 30 according to the present embodiment is made of metal, and has a substantially C-shaped holding piece 31 for holding the outer periphery of the outer cylinder 20, and an arm portion 32 extending in a tongue shape from the holding piece 31. .

狭持片３１は、外筒２０の外周に嵌め込まれて使用される。この狭持片３１は嵌め込まれているだけなので、外筒２０の軸方向に移動したり、外筒２０の周方向に回転させたりすることが可能である。このように狭持片３１を移動したり回転させたりすることによって、使用者の手の大きさなどに合わせてフック３０の位置を調整することができる。   The holding piece 31 is used by being fitted to the outer periphery of the outer cylinder 20. Since the holding piece 31 is only fitted, it can be moved in the axial direction of the outer cylinder 20 or rotated in the circumferential direction of the outer cylinder 20. By moving or rotating the holding piece 31 in this way, the position of the hook 30 can be adjusted according to the size of the user's hand.

アーム部３２は、人差し指の基節部に引っ掛けられるように山なりに湾曲している。本実施形態においては、アーム部３２にはフックカバー３３が取り付けられている。フックカバー３３は、合成樹脂やゴムなどの弾性材で形成されたチューブである。このフックカバー３３でアーム部３２を覆うことにより、金属製のアーム部３２が直接肌に触れないようになっている。   The arm portion 32 is curved in a mountain shape so as to be hooked on the proximal portion of the index finger. In the present embodiment, a hook cover 33 is attached to the arm portion 32. The hook cover 33 is a tube formed of an elastic material such as synthetic resin or rubber. By covering the arm portion 32 with the hook cover 33, the metal arm portion 32 is prevented from directly touching the skin.

上記した筆記具用補助具１０を筆記具４０に取り付ける場合には、まず図２（ａ）に示すように、内筒１１の頭部１２を回転させて、内筒１１と外筒２０との締め付けを緩める。この操作により、内筒１１が外筒２０から反挿入方向に移動し、保持部１６の突出片１６ａが広がって筆記具４０を挿入できる状態となる。   When attaching the writing instrument auxiliary tool 10 to the writing instrument 40, first, as shown in FIG. 2A, the head 12 of the inner cylinder 11 is rotated to tighten the inner cylinder 11 and the outer cylinder 20 together. loosen. By this operation, the inner cylinder 11 moves in the anti-insertion direction from the outer cylinder 20, and the protruding piece 16 a of the holding portion 16 spreads and the writing instrument 40 can be inserted.

筆記具４０を挿入できる状態にしたら、内筒１１の中に筆記具４０を挿入し、図２（ａ）に示すように、内筒１１の頭部１２を回転させて、内筒１１を締め付ける。この操作により、内筒１１が外筒２０に深く挿入され、保持部１６の突出片１６ａが縮径して筆記具４０を保持する。   When the writing instrument 40 is ready to be inserted, the writing instrument 40 is inserted into the inner cylinder 11, and the head 12 of the inner cylinder 11 is rotated to tighten the inner cylinder 11 as shown in FIG. By this operation, the inner cylinder 11 is inserted deeply into the outer cylinder 20, and the protruding piece 16 a of the holding portion 16 is reduced in diameter to hold the writing instrument 40.

筆記具４０に筆記具用補助具１０を取り付けたら、図３に示すように、まず第２凹部２３に人指し指の腹を合わせる。そして、第３凹部２４に中指の爪の根元を合わせる。次に、フック３０の位置を調節し、フック３０のアーム部３２を人差し指の基節部に引っ掛ける。最後に、第１凹部２２に親指の腹を合わせることで筆記具４０を正しく持つことができる。
なお、筆記具用補助具１０から筆記具４０を取り外す場合には、内筒１１の頭部１２を回転させて、内筒１１と外筒２０との締め付けを緩めればよい。 When the writing instrument auxiliary tool 10 is attached to the writing instrument 40, first, the index finger is placed in the second recess 23 as shown in FIG. Then, the base of the nail of the middle finger is aligned with the third recess 24. Next, the position of the hook 30 is adjusted, and the arm portion 32 of the hook 30 is hooked on the proximal portion of the index finger. Finally, the writing instrument 40 can be correctly held by aligning the belly of the thumb with the first recess 22.
When the writing instrument 40 is removed from the writing instrument auxiliary tool 10, the head 12 of the inner cylinder 11 may be rotated to loosen the tightening between the inner cylinder 11 and the outer cylinder 20.

なお、筆記具４０は、ボールペンやシャープペンなどの削る必要のない軸部４１を備えた筆記具４０であってもよい。このとき、筆記具４０は、鉛筆に近似したものを使用することが望ましい。具体的には、筆記具４０が一般的な鉛筆とほぼ同じ太さの軸部４１を備え、軸部４１の太さが全長に渡って一定であることが望ましい。また、頭部４３からペン先４２に至るまで、軸部４１の径よりも突出する部分がないように形成することが望ましい。このように鉛筆に近似したボールペンやシャープペンを使用すれば、ボールペンやシャープペン用の筆記具用補助具１０と鉛筆用の筆記具用補助具１０とを別々に用意しなくても、同じ筆記具用補助具１０をどちらにも使用することができる。   The writing instrument 40 may be a writing instrument 40 including a shaft portion 41 that does not need to be sharpened, such as a ballpoint pen or a mechanical pen. At this time, it is desirable to use a writing instrument 40 that approximates a pencil. Specifically, it is desirable that the writing instrument 40 includes a shaft portion 41 having a thickness approximately the same as that of a general pencil, and the thickness of the shaft portion 41 is constant over the entire length. In addition, it is desirable to form so as not to protrude from the diameter of the shaft portion 41 from the head 43 to the pen tip 42. By using a ballpoint pen or a mechanical pencil similar to a pencil in this way, the same writing instrument aid can be used without preparing the writing instrument auxiliary tool 10 for the ballpoint pen or the mechanical pencil and the writing instrument auxiliary tool 10 for the pencil separately. The tool 10 can be used for either.

なお、筆記具用補助具１０を鉛筆に使用した場合、筆記具用補助具１０によって鉛筆の軸部を延長することができるので、いわゆる鉛筆補助軸として使用することができる。   In addition, when the auxiliary tool 10 for writing tools is used for a pencil, since the axial part of a pencil can be extended by the auxiliary tool 10 for writing tools, it can be used as what is called a pencil auxiliary shaft.

以上説明したように、本実施形態によれば、筆記具４０を挿通可能な内筒１１と、前記内筒１１の外周に取り付けられる外筒２０と、を備え、前記内筒１１を前記外筒２０にねじ込むことで前記内筒１１が縮径して筆記具４０を保持することができる。すなわち、本実施形態に係る筆記具用補助具１０は、短くなった鉛筆を使用するための補助具として使用することができる。筆記具用補助具１０を鉛筆に取り付けることで鉛筆の軸部を延長することができ、短くなって持ちにくくなった鉛筆であっても使用することができる。そして、前記外筒２０の外周には、筆記具４０を持つ指の位置に凹部が形成されているため、この凹部に指を合わせて筆記具４０を持つことで正しい持ち方を習得することができる。このように、本発明に係る筆記具用補助具１０を使用すれば、単に筆記具４０の正しい持ち方を習得できるだけではなく、補助軸としても使うことができる。
また、内筒１１を外筒２０にねじ込むことで筆記具４０を保持する構造であるため、様
々な筆記具４０の太さに対応することができ、着脱も容易である。 As described above, according to the present embodiment, the inner cylinder 11 into which the writing instrument 40 can be inserted and the outer cylinder 20 attached to the outer periphery of the inner cylinder 11 are provided, and the inner cylinder 11 is connected to the outer cylinder 20. The inner cylinder 11 can be reduced in diameter by being screwed into the holder, and the writing instrument 40 can be held. That is, the writing instrument assisting tool 10 according to the present embodiment can be used as an assisting tool for using a shortened pencil. The pencil part can be extended by attaching the writing instrument auxiliary tool 10 to the pencil, and even a pencil that has become shorter and difficult to hold can be used. And since the recessed part is formed in the outer periphery of the said outer cylinder 20 in the position of the finger | toe with the writing instrument 40, the correct holding method can be learned by holding the writing instrument 40 with a finger | toe in this recessed part. Thus, if the writing instrument auxiliary tool 10 according to the present invention is used, it can be used not only to learn how to properly hold the writing instrument 40 but also as an auxiliary shaft.
Moreover, since it is the structure which hold | maintains the writing instrument 40 by screwing the inner cylinder 11 in the outer cylinder 20, it can respond to the thickness of various writing instruments 40, and attachment or detachment is also easy.

また、筆記具４０を持つ人差し指の基節部に引っ掛け可能なフック３０を備えるので、筆記具４０の傾きなどを正しい姿勢に保つことができる。このフック３０によって、更に正しい持ち方となるように促すことができる。   Moreover, since the hook 30 that can be hooked on the proximal portion of the index finger having the writing instrument 40 is provided, the inclination of the writing instrument 40 can be maintained in a correct posture. By this hook 30, it can be urged to be in a more correct way.

また、削る必要のない軸部４１を備えた筆記具４０（ボールペンやシャープペンなど）に筆記具用補助具１０を取り付けることも可能である。すなわち、従来は補助軸が不要であったボールペンやシャープペンに補助軸を取り付けることも可能である。この新しい発想は、「ボールペンやシャープペンを使用する大人が、まずは筆記具４０の正しい持ち方を習得すべきである」という考えに基づいている。   It is also possible to attach the writing instrument auxiliary tool 10 to a writing instrument 40 (such as a ballpoint pen or a mechanical pencil) having a shaft portion 41 that does not need to be cut. That is, it is possible to attach the auxiliary shaft to a ballpoint pen or a mechanical pen that conventionally does not require the auxiliary shaft. This new idea is based on the idea that “adults using ballpoint pens and mechanical pens should first learn how to hold the writing instrument 40 correctly”.

すなわち、子供に筆記具４０の正しい持ち方を教える前に、まずは筆記具用補助具１０を取り付けたボールペンやシャープペンを大人が使用して筆記具４０の正しい持ち方を習得する。そして、大人が筆記具４０の正しい持ち方を習得したら、筆記具用補助具１０を取り外して子供に与える。この筆記具用補助具１０は鉛筆にも同じものを使用することができるので、子供は筆記具用補助具１０を鉛筆に取り付けて、補助軸として使用するとともに、正しい持ち方を練習する。このとき、大人はすでに筆記具用補助具１０を使用しているので、その経験を生かして大人が子供を指導することができる。このような構成によれば、そもそも親が鉛筆の正しい持ち方を知らず、どう教えて良いか分からない、といった問題を解消することができる。   That is, before teaching a child how to properly hold the writing instrument 40, first, an adult uses a ballpoint pen or a mechanical pencil attached with the writing instrument auxiliary tool 10 to learn how to properly hold the writing instrument 40. When the adult learns how to properly hold the writing instrument 40, the writing instrument auxiliary tool 10 is removed and given to the child. Since the same writing instrument assisting tool 10 can be used as a pencil, the child attaches the writing instrument assisting tool 10 to the pencil and uses it as an auxiliary shaft, and also practice how to hold it correctly. At this time, since the adult has already used the writing instrument assisting tool 10, the adult can instruct the child using the experience. According to such a configuration, it is possible to solve the problem that the parent does not know how to hold the pencil in the first place and does not know how to teach it.
