ところで、編み針においては、使用中に容易に折れたり曲がったりしないこと、編み目を揃えやすいこと、編み針に巻き掛けた毛糸に他の編み針を通しやすいこと、毛糸との摩擦が少ないこと、編み針にサイズなどを刻印しやすいこと、刻印による表示が見やすいこと、刻印が毛糸に引掛からないこと、手触りがよいこと、などが要求される。これらの要求に対処することを意図して、編み針の材料を適切に選択したり編み針の全体形状を適切に選択したりすることも行われている。   By the way, with knitting needles, they do not bend or bend easily during use, it is easy to align the stitches, it is easy to pass other knitting needles through the yarn wound around the knitting needles, there is little friction with the yarns, the size of the knitting needles It is required that the markings are easily stamped, the marking display is easy to see, the markings do not catch on the yarn, and the touch is good. In order to cope with these demands, the material of the knitting needle is appropriately selected and the overall shape of the knitting needle is appropriately selected.

本考案は以上の状況の下でなされたものであり、編み針の軸部の形状に工夫を講じることによって、上掲したような様々な要求に対する満足度合いを従来例に比べて改善することのできる編み針を提供することを目的とする。   The present invention has been made under the above circumstances, and the degree of satisfaction with the various requirements as described above can be improved by devising the shape of the shaft portion of the knitting needle as compared with the conventional example. The object is to provide a knitting needle.

本考案に係る編み針は、軸部の先端が先尖り状又は鈎状に形作られている編み針であって、上記軸部が、円弧面によって形成されたコーナー部を挟む両側に平坦面を有してなる略正多角形の断面形状を有し、コーナー部を形成している上記円弧面の曲率半径が、上記略正多角形の内心から上記コーナー部までの距離に一致している、というものである。   A knitting needle according to the present invention is a knitting needle in which the tip of a shaft portion is formed in a pointed shape or a hook shape, and the shaft portion has flat surfaces on both sides sandwiching a corner portion formed by an arc surface. The radius of curvature of the circular arc surface forming the corner portion is equal to the distance from the inner center of the substantially regular polygon to the corner portion. It is.

このように構成された編み針によれば、編み目も揃えやすくなり、また、編み針に巻き掛けた毛糸に他の編み針を通しやすくなり、併せて、毛糸との摩擦も少なくなる。さらに、軸部の平坦面を利用してサイズなどを容易に刻印することが可能になり、刻印による表示も見やすくなる。そのうえ、刻印が毛糸に引掛からなくなり、手触りもよくなる。加えて、コーナー部を形成せずに単純に正多角形の断面形状とする場合と比べて、軸部の強度が向上する。   According to the knitting needle configured as described above, the stitches can be easily aligned, and other knitting needles can be easily passed through the yarn wound around the knitting needle, and friction with the yarn is also reduced. Furthermore, the size and the like can be easily stamped using the flat surface of the shaft portion, and the display by the stamp can be easily seen. In addition, the stamp is not caught on the yarn and the touch is also improved. In addition, the strength of the shaft portion is improved as compared with a case where the regular polygonal cross-sectional shape is simply formed without forming the corner portion.

本考案では、丸棒の外周面の間隔を隔てた複数箇所を削り取ることによって上記平坦面が形成され、相隣接する2つの平坦面の相互間のコーナー部が丸棒の上記外周面の一部を残存させてなる円弧面によって形成されている、ことが望ましい。これによれば、コーナー部に毛羽立ったようなささくれが生じにくい。   In the present invention, the flat surface is formed by scraping off a plurality of locations separated by an interval between the outer peripheral surfaces of the round bars, and a corner portion between two adjacent flat surfaces is a part of the outer peripheral surface of the round bar. It is desirable that it be formed by a circular arc surface that is left behind. According to this, it is hard to produce the fluff which fuzzed in the corner part.

本考案では、上記略正多角形が、同一幅の4つの上記平坦面と及び同一幅の4つの上記円弧面とを有する略正四角形である、という構成を採用することが可能である。これによっても、上記した作用が良好に発揮される。   In the present invention, it is possible to adopt a configuration in which the substantially regular polygon is a substantially regular quadrilateral having the four flat surfaces having the same width and the four arc surfaces having the same width. Also by this, the above-mentioned action is exhibited well.

以上説明したように、本考案に係る編み針によると、編み針の軸部の形状に工夫を講じるだけで、従来例に比べて、軸部の強度や、取扱性や使い勝手、刻印によるサイズなどの表示のしやすさなどが改善される。   As explained above, according to the knitting needle according to the present invention, it is possible to display the strength of the shaft, handling, usability, size by engraving, etc. compared to the conventional example only by devising the shape of the shaft of the knitting needle. The ease of handling is improved.

図1は本考案の実施形態に係る編み針Aの一部破断側面図、図2は図1の編み針AのII−II線に沿う部分の拡大断面図、図3及び図4は軸部の断面形状の説明図、図5は変形例の説明図、図6は使用状態説明図である。   1 is a partially cutaway side view of a knitting needle A according to an embodiment of the present invention, FIG. 2 is an enlarged cross-sectional view of a portion along the II-II line of the knitting needle A of FIG. 1, and FIGS. FIG. 5 is an explanatory diagram of a modification, FIG. 6 is an explanatory diagram of a use state.

図1に示した実施形態に係る編み針Aは棒針であり、まっすぐな軸部10の先端が先尖り状に形作られている。そして、図2に示したように、中実の軸部10が、円弧面によって形成されたコーナー部11を挟む両側に平坦面12を有してなる略正四角形の断面形状を有している。この編み針Aにおいては、図3に示したように、コーナー部11を形成している円弧面の曲率半径rが、略正四角形の内心Pからコーナー部11までの距離に一致している。ここで、略正四角形の内心Pの位置は、略正四角形の4つの辺に接する仮想線で示した内接円Cの中心の位置に一致する。   The knitting needle A according to the embodiment shown in FIG. 1 is a bar needle, and the tip of a straight shaft portion 10 is formed in a pointed shape. As shown in FIG. 2, the solid shaft portion 10 has a substantially square cross-sectional shape having flat surfaces 12 on both sides of a corner portion 11 formed by an arcuate surface. . In this knitting needle A, as shown in FIG. 3, the radius of curvature r of the circular arc surface forming the corner portion 11 coincides with the distance from the inner center P of the substantially regular square to the corner portion 11. Here, the position of the inner center P of the substantially regular quadrangle coincides with the position of the center of the inscribed circle C indicated by imaginary lines in contact with the four sides of the substantially regular quadrangle.

この編み針Aによれば、編み目も揃えやすくなることが判っている。また、編み針Aのサイズなどの刻印箇所として、平坦面12を選択することが可能になるので、そのようにすることによって刻印を容易に行うことができ、刻印による表示も見やすくなる。また、
コーナー部を形成せずに単純に正多角形の断面形状とする場合と比べて、軸部10の強度が向上する。
According to this knitting needle A, it has been found that the stitches can be easily aligned. Further, since the flat surface 12 can be selected as a marking location such as the size of the knitting needle A, the marking can be easily performed by doing so, and the display by the marking is also easy to see. Also,
The strength of the shaft portion 10 is improved as compared with the case where the cross-sectional shape is simply a regular polygon without forming the corner portion.

さらに、図6に例示したような使用状態においては、編み針Aにループ状に毛糸20を巻き掛けたときに、図1又は図2に示した軸部10の平坦面12とループ状の毛糸20との間に隙間ができやすいので、その隙間を利用して、一方の編み針Aに巻き掛けた毛糸20に他方の編み針Aを通しやすくなり、併せて、毛糸20との摩擦も少なくなるという利点がある。また、平坦面12に打設した刻印が毛糸20に引掛からなくなるという利点もある。そのほか、コーナー部11が円弧面になっていて角張っていないために手触りもよくなる。   Furthermore, in the use state illustrated in FIG. 6, when the yarn 20 is wound around the knitting needle A in a loop shape, the flat surface 12 of the shaft portion 10 and the loop yarn 20 shown in FIG. 1 or 2. Since it is easy to create a gap between the two yarns, it is easy to pass the other knitting needle A through the yarn 20 wound around one knitting needle A, and the friction with the yarn 20 is also reduced. There is. In addition, there is an advantage that the stamp formed on the flat surface 12 is not caught on the yarn 20. In addition, since the corner portion 11 is an arc surface and not angular, the touch is also improved.

図1又は図2に示したような軸部10が略正四角形の断面形状を有する編み針Aは、図4に説明的に示したように、仮想線で示した円形の断面形状を有する丸棒15の90度おきの間隔を隔てた4箇所(図中のハッチング箇所)を一定量だけ削り取ることによって4つの平坦面12を形成すると共に、相隣接する2つの平坦面12,12の相互間のコーナー部11を、元の丸棒15の外周面の一部を残存させてなる円弧面によって形成することによって製作することが可能である。このようにして製作した編み針Aでは、材料が木材や竹であっても、軸部10のコーナー部11に毛羽立ったようなささくれが生じにくいために、製作によって生じたささくれを取り除く手間を省略することができるという利点もある。   As shown in FIG. 4, the knitting needle A in which the shaft portion 10 as shown in FIG. 1 or FIG. 2 has a substantially square cross-sectional shape is a round bar having a circular cross-sectional shape indicated by an imaginary line. Four flat surfaces 12 are formed by scraping four portions (hatched portions in the figure) separated by a certain amount of 15 at intervals of 15 degrees to form four flat surfaces 12, and between two adjacent flat surfaces 12, 12. The corner portion 11 can be manufactured by forming a circular arc surface in which a part of the outer peripheral surface of the original round bar 15 is left. In the knitting needle A manufactured in this way, even if the material is wood or bamboo, since it is difficult to generate fluffing at the corner portion 11 of the shaft portion 10, the trouble of removing the production generated by the manufacturing is omitted. There is also an advantage of being able to.

軸部の断面形状が略正四角形以外の略正多角形である場合も同様に、丸棒の外周面の間隔を隔てた複数箇所を削り取ることによって平坦面を形成し、相隣接する2つの平坦面の相互間のコーナー部に丸棒の外周面の一部を、残存させてなる円弧面によって形成しておくことが可能である。   Similarly, when the cross-sectional shape of the shaft portion is a substantially regular polygon other than a substantially regular square, a flat surface is formed by scraping a plurality of portions spaced apart from each other on the outer peripheral surface of the round bar, and two adjacent flat surfaces are formed. It is possible to form a part of the outer peripheral surface of the round bar at the corner portion between the surfaces by a remaining arc surface.

以上説明した実施形態では、軸部10の断面形状が略正四角形の編み針Aを主に説明したけれども、この点は、軸部10の断面形状を略正四角形以外の略正多角形、たとえば図5に例示したような略正三角形に形成することも可能である。このものも、軸部10が、円弧面によって形成されたコーナー部11を挟む両側に平坦面12を有している。また、図示していないけれども、コーナー部11を形成している円弧面の曲率半径は、略正三角形の内心からコーナー部11までの距離に一致している。さらに、このものに関しても、仮想線で示した丸棒15の外周面の間隔を隔てた3箇所を削り取ることによって平坦面12が形成され、相隣接する2つの平坦面12,12の相互間のコーナー部11が丸棒15の外周面の一部を残存させてなる円弧面によって形成されている。   In the embodiment described above, the knitting needle A having a substantially square shape in cross section of the shaft portion 10 has been mainly described. However, in this respect, the cross section shape of the shaft portion 10 is a substantially regular polygon other than the substantially square shape, for example, FIG. It is also possible to form a substantially equilateral triangle as illustrated in FIG. In this case, the shaft portion 10 has flat surfaces 12 on both sides sandwiching the corner portion 11 formed by the circular arc surface. Although not shown, the radius of curvature of the arc surface forming the corner portion 11 matches the distance from the inner center of the substantially equilateral triangle to the corner portion 11. Further, also in this case, the flat surface 12 is formed by scraping off the three portions separated by the interval between the outer peripheral surfaces of the round bar 15 indicated by phantom lines, and the two flat surfaces 12 and 12 adjacent to each other are formed. The corner portion 11 is formed by an arc surface formed by leaving a part of the outer peripheral surface of the round bar 15.

本考案に係る編み針には、上記した棒針に限定されることはなく、軸部の先端が鈎状に形作られている鈎針や、その他の輪針、なわ編み針なども含まれる。また、編み針に使われる材料は、木や竹のほか、金属、プラスチックなどであってもよい。   The knitting needle according to the present invention is not limited to the above-described bar needle, and includes a hook needle in which the tip of the shaft portion is shaped like a hook, other ring needles, a knitting needle, and the like. Further, the material used for the knitting needle may be metal, plastic, etc. in addition to wood and bamboo.
