Description

本発明は、略踝部上部までの丈を有する短靴下に関するものである。 The present invention relates to short socks that reach almost to the top of the ankle.

従来より、足首までの丈を有する短靴下が知られている。この種の短靴下１０１として、足首部１０３から口ゴム端１０２までの脚部１０４を締付組織とし、その編糸として引き揃えの表糸と弾性を有する添え糸と挿入する弾性糸との３本を使用し、そして、締付組織をリブ編、添え糸編、挿入編、タック編の組合せ組織とすることにより、ずり落ちが完全に防止されるというものがあった（図８参照）。ここで、図８は従来の短靴下を裏返した状態を示す平面図である。 Short socks that reach the ankle have been known for some time. In this type of short sock 101, the leg section 104 from the ankle section 103 to the end of the cuff 102 is made of a tightening structure, and three yarns are used as the knitting yarn: a parallel face yarn, an elastic supporting yarn, and an inserted elastic yarn. The tightening structure is made of a combination of rib knitting, supporting yarn knitting, insert knitting, and tuck knitting, which completely prevents the socks from slipping down (see Figure 8). Here, Figure 8 is a plan view showing a conventional short sock turned inside out.

しかしながら、従来の靴下１０１では、足首部１０３から口ゴム端１０２までの脚部１０４の上部全体を締付組織としているため、ずり落ちは完全に防止されることができるが、弾性糸（ゴム糸など）を使用している足首部１０３から口ゴム端１０２までの締付組織部分が足首やふくらはぎに食い込むことにより、足首やふくらはぎにゴムの締め付け跡が付くとともに、痛みや痒み等不快感を与えるという問題があった。また、靴下を履く際には、履き口を広げる必要があるが、足首部１０３から口ゴム端１０２までを締付組織としているため、弾性糸（ゴム糸など）により締め付けられている口ゴム端１０２を拡開するためには強い力で強力に広げなくてはならず、履き難いという問題もあった。 However, in conventional socks 101, the entire upper part of the leg part 104 from the ankle part 103 to the cuff rubber end 102 is made of tightening tissue, so slipping down is completely prevented. However, the tightening tissue part from the ankle part 103 to the cuff rubber end 102, which uses elastic thread (rubber thread, etc.), digs into the ankle or calf, leaving marks on the ankle or calf from the tightening of the rubber, and causing discomfort such as pain and itching. In addition, when putting on the socks, it is necessary to widen the opening, but because the tightening tissue is from the ankle part 103 to the cuff rubber end 102, a strong force must be used to open the cuff rubber end 102, which is tightened by the elastic thread (rubber thread, etc.), making it difficult to put on.

本発明は上記問題点に鑑みてなされたもので、ずり落ちにくくすることができるとともに、十分な履きやすさを有する短靴下を提供することを目的とする。 The present invention was made in consideration of the above problems, and aims to provide short socks that are difficult to slip down and are also sufficiently easy to wear.

上記課題を解決し上記目的を達成するために、本発明のうち第１の態様に係るものは、略踝部上部までの丈を有する短靴下であって、ゴム糸が編み込まれて編成され、装着者の足を挿入するための装着時に略踝部上部の足首に位置する履き口の全周に亘って設けられた口ゴム部と、口ゴム部より伸縮率が低く編成され、口ゴム部の横断面の前後方向略中央断面より後方で、口ゴム部の略上端から略下端までの高さで、口ゴム部の周方向に沿って上辺が短く下辺が長い略台形形状で形成された口ゴム後部締付部と、口ゴム部より伸縮率が低く編成され、口ゴム部の横断面の前後方向略中央断面より後方で、装着時の踵骨の略後端と口ゴム部の間を介して左右周方向に沿って口ゴム後部締付部より横長さが長く、上辺が口ゴム後部締付部の下辺と略同一長さで、下辺が上辺より長い略台形形状で形成された口ゴム後方下部締付部と、を有し、口ゴム後部締付部と口ゴム後方下部締付部は、口ゴム後部締付部の上辺が短く下辺が長い略台形形状で形成され、口ゴム後方下部締付部の上辺が口ゴム後部締付部の下辺と略同一長さで、下辺が上辺より長い略台形形状で形成されているので、下方の伸縮力が小さくなることによりずり落ちにくくすることができるとともに、口ゴム後部締付部および口ゴム後方下部締付部を上辺が下辺より短い台形形状で形成させているので、上辺と下辺が同じ長さの形状で形成させているのと比較して、上方の伸縮力が下方の伸縮率より大きくなることにより、装着する際に履き口を広げやすく履きやすいことを特徴とするものである。
 In order to solve the above problems and achieve the above objects, a first aspect of the present invention relates to a short sock having a length reaching approximately above the ankle, which comprises: a cuff rubber part that is knitted with a knitted rubber thread and provided around the entire circumference of an opening that is located at the ankle approximately above the ankle when the sock is put on for inserting a wearer's foot; a rear cuff rubber fastening part that is knitted with a lower elasticity than the cuff rubber part, and is formed in a substantially trapezoidal shape with a short upper side and a long lower side along the circumferential direction of the cuff rubber part, at a height from approximately the upper end to approximately the lower end of the cuff rubber part, posterior to approximately the central cross section in the front-to-rear direction of the cross section of the cuff rubber part; and a rear lower fastening part at the rear of the mouth rubber which is formed in a generally trapezoidal shape with the upper side of the rear fastening part being shorter and the lower side being longer than the upper side, and the rear fastening part at the rear of the mouth rubber and the rear lower fastening part at the rear of the mouth rubber are formed in a generally trapezoidal shape with the upper side of the rear fastening part at the rear of the mouth rubber being shorter and the upper side of the rear fastening part at the rear of the mouth rubber being longer than the upper side, thereby reducing the downward stretching force and making it difficult for the gauze to slip down , and since the rear fastening part at the rear of the mouth rubber and the rear lower fastening part at the rear of the mouth rubber are formed in a trapezoidal shape with the upper side shorter than the lower side, compared to a shape in which the upper and lower sides are formed to be the same length, the upward stretching force is greater than the downward stretching force, making it easier to widen the opening when putting on the gauze and easier to put on.

本発明によれば、口ゴム部より伸縮率が低く編成され、口ゴム部の横断面の前後方向略中央断面より後方で、装着時の踵骨の略後端と口ゴム部の間を介して左右周方向に沿って口ゴム後部締付部より横長さが長く形成された口ゴム後方下部締付部をさらに有しているので、踵骨の略後端と口ゴム部の間を介して左右周方向に沿って形成された口ゴム後方下部締付部により締め付けられることによりさらにずり落ちにくくすることができるとともに、口ゴム後方下部締付部が口ゴム部の横断面の前後方向略中央断面より後方のみに形成されているので、短靴下を履く際に履き口を十分に広げることができ、十分な履きやすさを有することができる。さらに、口ゴム後部締付部の上辺が短く下辺が長い略台形形状で形成され、口ゴム後方下部締付部の上辺が口ゴム後部締付部の下辺と略同一長さで、下辺が上辺より長い略台形形状で形成されているので、下辺の長さが大きい略台形形状の口ゴム後部締付部および口ゴム後方下部締付部の伸縮力によりさらにずり落ちにくくすることができるとともに、上辺の長さが小さい略台形形状の口ゴム後部締付部および口ゴム後方下部締付部により十分な履きやすさを有することができる。
 According to the present invention , the cuff rubber rear lower fastening portion is knitted to have a lower elasticity than the cuff rubber, and is formed rearward of approximately the central section in the front-to-back direction of the cross section of the cuff rubber, and is longer in width than the cuff rubber rear fastening portion along the left-right circumferential direction, between approximately the rear end of the calcaneus and the cuff rubber when worn. Therefore, the cuff rubber rear lower fastening portion, which is formed along the left-right circumferential direction between approximately the rear end of the calcaneus and the cuff rubber when worn, tightens the sock, making it even less likely to slip down.In addition, because the cuff rubber rear lower fastening portion is formed only rearward of approximately the central section in the front-to-back direction of the cross section of the cuff rubber, the opening can be sufficiently widened when putting on the short socks, making them sufficiently easy to put on. Furthermore, the upper edge of the rear fastening portion of the mouth rubber is short and the lower edge is long, and the upper edge of the rear lower fastening portion of the mouth rubber is approximately the same length as the lower edge of the rear fastening portion of the mouth rubber, and the lower edge is approximately trapezoidal and longer than the upper edge.Therefore, the elastic force of the approximately trapezoidal rear fastening portion of the mouth rubber and the rear lower fastening portion of the mouth rubber, which have a longer lower edge, makes it even less likely to slip down, and the approximately trapezoidal rear fastening portion of the mouth rubber and the rear lower fastening portion of the mouth rubber, which have a shorter upper edge, make the mouth rubber sufficiently easy to put on .

本発明によれば、ずり落ちにくくすることができるとともに、十分な履きやすさを有することができる。 The present invention makes it possible to prevent the footwear from slipping down and to make it easy to wear.

以下、本発明の短靴下の一実施形態について図面を参照にしながら説明する。ここで、図１は本発明の一実施形態における短靴下の上面図であり、図２は同短靴下の下面図であり、図３は同短靴下の外側面図であり、図４は同短靴下の内側面図である。 One embodiment of the short socks of the present invention will be described below with reference to the drawings. Here, Fig. 1 is a top view of the short socks in one embodiment of the present invention, Fig. 2 is a bottom view of the short socks, Fig. 3 is an outer side view of the short socks, and Fig. 4 is an inner side view of the short socks.

図１～図４に示すように、短靴下１は、踝部６上部までの丈を有する靴下（図５～図７参照）であって、口ゴム部２と、口ゴム後部締付部３と、口ゴム後方下部締付部４を有している。ここで、「踝部６上部までの丈を有する靴下」とは、丈の長さが踝部６上部を超えない靴下であり、踝部６上部以下の丈を有する靴下と同意である。一般的な短靴下は、丈が踝部６上部までしかないので、装着者が歩行や激しいスポーツなどを行なうことにより、短靴下の踵部７付近は足先方向に引っ張られてずれてしまいやすくなるが、短靴下１は、後述するとおり、口ゴム後部締付部３が短靴下１の口ゴム部２後方で短靴下１の踵部７付近が足先方向に引っ張られてずり落ちてしまうことを阻止するように作用するので、口ゴム後部締付部３の伸縮力により短靴下１がずり落ちにくくすることができる。これについては、具体的に後述する。なお、本実施形態では、踝部６上部までの丈を有する短靴下１（図５~図７参照）を用いたが、これに限らず、略踝部６上部までの丈を有する短靴下（図５~図７参照）や、略足首までの丈を有する短靴下を用いてもよい。ここで、「略踝部６上部までの丈を有する短靴下」とは、丈の長さが踝部６上部を少し超える靴下を含む短靴下のことである。また、本実施形態の短靴下１は、親指を収納する親指袋８ａと他の４本指を収納する４本指袋８ｂからなる指袋８を有する足袋型の短靴下を用いたが、これに限らず、５本指をそれぞれ別々に収納する指袋を有する短靴下であってもよい。 As shown in Figures 1 to 4, the short sock 1 is a sock that reaches the top of the ankle 6 (see Figures 5 to 7), and has a cuff rubber section 2, a rear cuff rubber tightening section 3, and a rear lower cuff rubber tightening section 4. Here, "a sock that reaches the top of the ankle 6" means a sock whose length does not exceed the top of the ankle 6, and is the same as a sock whose length is below the top of the ankle 6. Since typical short socks only reach the top of the ankle 6, when the wearer walks or plays vigorous sports, the heel 7 of the short sock is pulled toward the toes and easily slips down. However, as described below, the rear cuff rubber tightening section 3 of the short sock 1 acts to prevent the heel 7 of the short sock 1 from being pulled toward the toes behind the cuff rubber section 2 of the short sock 1, so that the elasticity of the rear cuff rubber tightening section 3 makes it difficult for the short sock 1 to slip down. This will be described in detail later. In this embodiment, short socks 1 (see Figs. 5-7) with a length up to the top of the ankle 6 are used, but the present invention is not limited to this, and short socks with a length up to almost the top of the ankle 6 (see Figs. 5-7) or short socks with a length up to almost the ankle may be used. Here, "short socks with a length up to almost the top of the ankle 6" refers to short socks including socks whose length is slightly longer than the top of the ankle 6. In addition, the short socks 1 in this embodiment are tabi-type short socks with toe pockets 8 consisting of a thumb pocket 8a for storing the big toe and a four-toe pocket 8b for storing the other four toes, but the present invention is not limited to this, and short socks with toe pockets for storing each of the five toes separately may be used.

口ゴム部２は、ゴム糸が織り込まれて編成され、装着者の足を挿入するための履き口５の全周に亘って設けられている。ここで、「履き口５の全周に亘って設けられている」とは、履き口５の全周に設けられているものに限らず、履き口５の全周の範囲に設けられていれば、履き口５の一部に設けられていない部分があってもよい。この口ゴム部２は、丸編機を用いて、ゴム編みを行ないつつ、ゴム糸を複数コース挿入する流し込みによって形成される。そして、口ゴム部２の丈及びゴム糸のコース数は適宜に設定することができ、例えば４～１０ｍｍ程度の丈にゴム糸を３～１０コース程度挿入することもできる。この口ゴム部２は、編地が折り返されて二重になった袋編で形成されている。なお、本実施形態では、口ゴム部２を、丸編機を用いて、ゴム編みを行ないつつ、ゴム糸を複数コース挿入する流し込みによって形成させたが、これに限らず、口ゴム部２をゴム糸を横糸として挿入したリブ編み、平編みまたはメリヤス編みにより形成させてもよい。また、本実施形態では、口ゴム部２を二重になった袋編のものとしたが、これに限らず、編地が一重になったものとしてもよい。 The rubber cuff 2 is knitted with rubber threads woven in, and is provided around the entire circumference of the opening 5 into which the wearer's foot is inserted. Here, "provided around the entire circumference of the opening 5" does not necessarily mean that it is provided around the entire circumference of the opening 5, but may be provided around the entire circumference of the opening 5, and may be provided in some parts of the opening 5. The rubber cuff 2 is formed by inserting multiple courses of rubber thread while performing rubber knitting using a circular knitting machine. The length of the rubber cuff 2 and the number of courses of rubber thread can be set appropriately, and for example, 3 to 10 courses of rubber thread can be inserted to a length of about 4 to 10 mm. The rubber cuff 2 is formed by bag knitting in which the knitted fabric is folded back and doubled. In this embodiment, the rubber cuff 2 is formed by inserting multiple courses of rubber thread while performing rubber knitting using a circular knitting machine, but this is not limited to this, and the rubber cuff 2 may be formed by rib knitting, flat knitting, or stockinette knitting with rubber threads inserted as weft. In addition, in this embodiment, the cuff rubber portion 2 is made of double-layered tubular knitting, but this is not limited to this, and the knitting may be single-layered.

口ゴム後部締付部３は、口ゴム部２より伸縮率が低く編成され、その口ゴム部２の横断面の前後方向中央断面より後方で、口ゴム部２の周方向に沿って形成されている。ここで、「口ゴム部２の横断面の前後方向中央断面」とは、「口ゴム部２（中空形状）の横断面の前後方向中央部分の縦方向断面である。これは、短靴下１（口ゴム部２）の左右を中央方向に山型に折り曲げた口ゴム部２の横断面の前後方向中央部分の縦方向断面であると同じである。ここで、「口ゴム部２の横断面の前後方向中央部分の縦方向断面」の「縦方向断面」は、短靴下１が装着され履き口５が地面と略平行になった状態での「縦方向断面」である。このように、口ゴム後部締付部３は、口ゴム部２の横断面の前後方向中央部分の縦方向断面の後方に形成されている。すなわち、口ゴム後部締付部３は、口ゴム部２の後方側に設けられている。また、口ゴム後部締付部３は、口ゴム部２に重ね合わされながら編成されている。具体的には、口ゴム後部締付部３は、カットボス編み（テーピング編み）により編成されることにより、口ゴム部２より伸縮率が低く編成され、また、上辺が下辺より短い略台形形状で形成されている。このように、口ゴム後部締付部３が口ゴム部２の横断面の前後方向中央断面より後方の範囲内で、口ゴム部２の伸縮率より低く編成されていることによりずり落ちにくくすることができるとともに、口ゴム後部締付部３が口ゴム部２の横断面の前後方向中央断面より後方、すなわち、略外側踝部６ａ後端部および略内側踝部６ｂ後端部より後方付近に形成されているので、短靴下１を履く際に履き口５を十分に広げることができ十分な履きやすさを有することができる。ここで、「カットボス編み」とは、地糸の上に別の糸を重ねて編成する場合に、地糸からなる編地の部分的な領域に別の糸を編みこんで編成することであり、本実施形態では、地糸の上にナイロン糸を重ねて編成する場合に、地糸からなる編地の部分的な領域にナイロン糸を編みこんで編成されている。このように、「カットボス編み」を用いることにより、カットボス編みで編まれた部分の伸縮率を低くし締め付け力を向上させることができる。また、口ゴム後部締付部３は、口ゴム部２の上端から下端までの高さで形成されているので、短靴下１をずれ落ちにくくするための十分な高さを有することにより、さらにずり落ちにくくすることができる。なお、本実施形態では、口ゴム後部締付部３を口ゴム部２の上端から下端までの高さで形成させたが、これに限らず、口ゴム部２の略上端から略下端までの高さで形成させてもよく、さらに、口ゴム部２の上端から下端の高さ方向の一部（略中央部など）に形成させてもよい。また、本実施形態では、口ゴム後部締付部３を口ゴム部２の横断面の前後方向中央断面より後方に形成させたが、これに限らず、口ゴム部２の横断面の前後方向略中央断面より後方に形成させてもよく、また、略外側踝部６ａ（前端部、前後方向中間部、後端部など）および略内側踝部６ｂ（前端部、前後方向中間部、後端部など）より後方に形成させてもよい。また、本実施形態では、口ゴム後部締付部３をカットボス編みにより編成されたが、これに限らず、タック編みにより編成してもよい。このように、口ゴム後部締付部３をタック編みにより編成させることによっても、口ゴム部２を大きな締付力で締め付けることができる。ここで、「タック編み」とは、生地を編成する際に、ある編み目を作らないで、次のコースを編むときに一緒に編み目を作るもので、編針から編み目を脱出させないようにすることにより、編針のフック又は針幹の前の編み目とともに保持し、例えば次の給糸により編み目を形成する時に同時に複数の編み目をくぐって編み糸を引き出して新しい編み目を作る編み方である。 The rear cuff fastening section 3 is knitted with a lower stretch rate than the cuff rubber section 2, and is formed behind the central cross section in the front-to-back direction of the cross section of the cuff rubber section 2 along the circumferential direction of the cuff rubber section 2. Here, the "central cross section in the front-to-back direction of the cross section of the cuff rubber section 2" refers to the vertical cross section of the central part in the front-to-back direction of the cross section of the cuff rubber section 2 (hollow shape). This is the same as the vertical cross section of the central part in the front-to-back direction of the cross section of the cuff rubber section 2 in which the left and right sides of the short sock 1 (cuff rubber section 2) are folded in a mountain shape toward the center. Here, the "vertical cross section" of the "vertical cross section of the central part in the front-to-back direction of the cross section of the cuff rubber section 2" refers to the "vertical cross section" when the short sock 1 is worn and the opening 5 is approximately parallel to the ground. In this way, the rear cuff fastening section 3 is formed behind the vertical cross section of the central part in the front-to-back direction of the cross section of the cuff rubber section 2. In other words, the rear cuff fastening section 3 is provided on the rear side of the cuff rubber section 2. The rear cuff fastening portion 3 is knitted while overlapping the cuff rubber portion 2. Specifically, the rear cuff fastening portion 3 is knitted by cut boss knitting (taping knitting) so that it has a lower stretch rate than the cuff rubber portion 2 and is formed in a substantially trapezoidal shape with its upper side shorter than its lower side. In this way, the rear cuff fastening portion 3 is knitted with a lower stretch rate than the cuff rubber portion 2 within a range behind the central cross section in the front-to-rear direction of the cross section of the cuff rubber portion 2, making it difficult for the cuff rubber portion 3 to slip down, and since the rear cuff fastening portion 3 is formed behind the central cross section in the front-to-rear direction of the cross section of the cuff rubber portion 2, i.e., near the rear of the rear end of the outer ankle portion 6a and the rear end of the inner ankle portion 6b, the opening 5 can be sufficiently widened when putting on the short sock 1, making it sufficiently easy to put on. Here, "cut boss knitting" refers to knitting a partial area of the knitted fabric made of ground yarn when another yarn is layered on top of the ground yarn, and knitting the fabric. In this embodiment, when a nylon yarn is layered on top of the ground yarn, the nylon yarn is knitted in a partial area of the knitted fabric made of ground yarn. In this way, by using "cut boss knitting", the stretch rate of the part knitted with cut boss knitting can be reduced and the tightening force can be improved. In addition, since the rear cuff rubber tightening part 3 is formed at a height from the upper end to the lower end of the cuff rubber part 2, it has a sufficient height to prevent the short sock 1 from slipping down, and therefore it can be made even more difficult to slip down. In this embodiment, the rear cuff rubber tightening part 3 is formed at a height from the upper end to the lower end of the cuff rubber part 2, but this is not limited to this, and it may be formed at a height from approximately the upper end to approximately the lower end of the cuff rubber part 2, and further, it may be formed at a part in the height direction (such as approximately the center) from the upper end to the lower end of the cuff rubber part 2. In this embodiment, the rear tightening part 3 of the mouth rubber is formed behind the central cross section in the front-to-rear direction of the cross section of the mouth rubber 2, but this is not limited thereto, and it may be formed behind the approximately central cross section in the front-to-rear direction of the cross section of the mouth rubber 2, or it may be formed behind the approximately outer malleolus part 6a (front end, front-to-rear middle part, rear end, etc.) and the approximately inner malleolus part 6b (front end, front-to-rear middle part, rear end, etc.). In this embodiment, the rear tightening part 3 of the mouth rubber is knitted by cut boss knitting, but this is not limited thereto, and it may be knitted by tuck knitting. In this way, the mouth rubber 2 can be tightened with a large tightening force by knitting the rear tightening part 3 of the mouth rubber by tuck knitting. Here, "tuck knitting" refers to a knitting method in which, when knitting fabric, a certain stitch is not made, but is made together with the next course when knitting. By preventing the stitch from escaping from the knitting needle, it is held together with the previous stitch on the hook or needle shaft of the knitting needle, and when forming a stitch with the next yarn feed, for example, the knitting yarn is pulled through multiple stitches at the same time to make a new stitch.

口ゴム後方下部締付部４は、口ゴム部２より伸縮率が低く編成され、その口ゴム部２の横断面の前後方向中央断面より後方で、装着時の踵骨９（図５参照）の後端と口ゴム部２の間を介して左右周方向に沿って口ゴム後部締付部３より横長さが長く形成されている。このように、口ゴム後方下部締付部４は、口ゴム部２より下部に設けられ、口ゴム部２の横断面の前後方向中央部分の縦方向断面の後方に形成されている。すなわち、口ゴム後方下部締付部４は、口ゴム部２の後方側の口ゴム部２より下部に形成されている。具体的には、口ゴム後方下部締付部４は、カットボス編み（テーピング編み）により編成されることにより口ゴム部２より伸縮率が低く編成され、また、上辺が口ゴム後部締付部３の下辺と同一長さで、下辺が上辺より長い略台形形状で形成されている。このように、口ゴム後方下部締付部４が口ゴム部２の横断面の前後方向中央断面より後方の範囲内で、口ゴム部２の伸縮率より低く編成されていることにより、口ゴム後部締付部３を補強して、さらにずり落ちにくくすることができるとともに、口ゴム後方下部締付部４が口ゴム部２の横断面の前後方向中央断面より後方に形成されているので、短靴下１を履く際に履き口５を十分に広げることができ十分な履きやすさを有することができる。なお、本実施形態では、口ゴム後方下部締付部４を口ゴム部２の横断面の前後方向中央断面より後方に形成させたが、これに限らず、口ゴム部２の横断面の前後方向略中央断面より後方に形成させてもよい。また、本実施形態では、口ゴム後方下部締付部４を装着時の踵骨９の後端と口ゴム部２の間を介して左右周方向に沿って形成させたが、これに限らず、装着時の踵骨９の略後端と口ゴム部２の間を介して左右周方向に沿って形成させてもよい。また、口ゴム後方下部締付部４の上辺を口ゴム後部締付部３の下辺と同一長さで形成させたが、これに限らず、口ゴム後方下部締付部４の上辺を口ゴム後部締付部３の下辺と略同一長さで形成させてもよく、他の長さにより形成させてもよい。また、本実施形態では、口ゴム後方下部締付部４をカットボス編みにより編成されたが、これに限らず、タック編みにより編成してもよい。このように、口ゴム後方下部締付部４をタック編みにより編成させることによっても、口ゴム部２を大きな締付力で締め付けることができる。 The rear lower fastening part 4 of the mouth rubber is knitted with a lower stretch rate than the mouth rubber part 2, and is formed to be longer in the horizontal direction than the rear fastening part 3 of the mouth rubber, between the rear end of the calcaneus 9 (see FIG. 5) and the mouth rubber part 2 when worn, rear of the center of the cross section of the mouth rubber part 2 in the front-to-back direction. In this way, the rear lower fastening part 4 of the mouth rubber is provided below the mouth rubber part 2, and is formed behind the vertical cross section of the center of the front-to-back direction of the cross section of the mouth rubber part 2. In other words, the rear lower fastening part 4 of the mouth rubber is formed below the mouth rubber part 2 on the rear side of the mouth rubber part 2. Specifically, the rear lower fastening part 4 of the mouth rubber is knitted with a lower stretch rate than the mouth rubber part 2 by being knitted by cut boss knitting (taping knitting), and is formed in a substantially trapezoid shape with the upper side being the same length as the lower side of the mouth rubber rear fastening part 3 and the lower side being longer than the upper side. In this way, the rear lower fastening part 4 of the cuff rubber is knitted in a range behind the central cross section in the front-to-back direction of the cross section of the cuff rubber 2 with a lower stretch rate than the cuff rubber 2, thereby reinforcing the rear fastening part 3 of the cuff rubber and making it more difficult to slip down, and since the rear lower fastening part 4 of the cuff rubber is formed behind the central cross section in the front-to-back direction of the cross section of the cuff rubber 2, the opening 5 can be sufficiently widened when putting on the short sock 1, making it easy to put on. In this embodiment, the rear lower fastening part 4 of the cuff rubber is formed behind the central cross section in the front-to-back direction of the cross section of the cuff rubber 2, but this is not limited thereto, and it may be formed behind the approximately central cross section in the front-to-back direction of the cross section of the cuff rubber 2. In this embodiment, the rear lower fastening part 4 of the cuff rubber is formed along the left-to-right circumferential direction between the rear end of the calcaneus 9 and the cuff rubber 2 when worn, but this is not limited thereto, and it may be formed along the left-to-right circumferential direction between the approximately rear end of the calcaneus 9 and the cuff rubber 2 when worn. In addition, the upper edge of the rear lower fastening portion 4 of the mouth rubber is formed to be the same length as the lower edge of the rear fastening portion 3 of the mouth rubber, but this is not limited thereto, and the upper edge of the rear lower fastening portion 4 of the mouth rubber may be formed to be approximately the same length as the lower edge of the rear fastening portion 3 of the mouth rubber, or may be formed to be another length. In addition, in this embodiment, the rear lower fastening portion 4 of the mouth rubber is knitted by cut boss knitting, but this is not limited thereto, and it may be knitted by tuck knitting. In this way, knitting the rear lower fastening portion 4 of the mouth rubber by tuck knitting also allows the mouth rubber portion 2 to be tightened with a large tightening force.

次に、使用者が短靴下１を装着した場合に、短靴下１の「口ゴム部２に設けられた口ゴム後部締付部３」と「口ゴム部２下部に設けられた口ゴム後方下部締付部４」により、ずり落ちにくくなる作用の状況、および十分な履きやすさを有することについて、図５～図７を参照にして説明する。ここで、図５は本発明の一実施形態における短靴下が使用者により装着され内部骨が表示された外側面図であり、図６は同短靴下が使用者により装着され内部骨が表示された外側後方斜視図であり、図７は同短靴下が使用者により装着され内部骨が表示された内側後方斜視図である。 Next, with reference to Figs. 5 to 7, we will explain how the "rear cuff rubber fastening portion 3 on the cuff rubber portion 2" and the "rear lower cuff rubber fastening portion 4 on the lower part of the cuff rubber portion 2" of the short socks 1 prevent the socks from slipping down when the user puts them on, and how they are easy to put on. Here, Fig. 5 is an outer side view of a short sock according to one embodiment of the present invention, with the internal bones displayed, Fig. 6 is an outer rear perspective view of the short sock according to one embodiment of the present invention, with the internal bones displayed, and Fig. 7 is an inner rear perspective view of the short sock according to one embodiment of the present invention, with the internal bones displayed.

短靴下１は、上述したように、ゴム糸が織り込まれて編成され、履き口の全周に亘って設けられた口ゴム部２と、口ゴム部２の横断面の前後方向中央断面より後方に形成された口ゴム後部締付部３を有している。そして、口ゴム部２のゴム糸の伸縮力により、短靴下１を適度にずり落ちにくくすることができる。しかしながら、歩行時や激しいスポーツを行なうと、短靴下１の踵部７付近が足先方向に引っ張られてずり落ちてしまうことが多くあるが、口ゴム部２の横断面の前後方向中央断面より後方に形成された口ゴム後部締付部３は、短靴下１の口ゴム部２後方で短靴下１の踵部７付近が足先方向に引っ張られてずり落ちてしまうことを阻止するように作用するので、口ゴム部２より伸縮率が低く編成された口ゴム後部締付部３の伸縮力により短靴下１がずり落ちにくくすることができるとともに、口ゴム後部締付部３が口ゴム部２の横断面の前後方向中央断面より後方、すなわち、口ゴム部２の略外側踝部６ａ後端部および略内側踝部６ｂ後端部より後方付近に設けられているので、履き口５の開口部も強い締付力で締め付けられず、短靴下１を履く際に履き口５を十分に広げることができ十分な履きやすさを有することができる。さらに、口ゴム後部締付部３は、口ゴム部２の上端から下端までの高さで形成されているので、口ゴム部２の伸縮率より低く編成された口ゴム後部締付部３が、靴下をずれ落ちにくくするための十分な高さを有することによりさらにずり落ちにくくすることができる。 As described above, the short socks 1 have a cuff rubber section 2 that is knitted with woven rubber thread and is provided around the entire circumference of the opening, and a rear cuff rubber fastening section 3 that is formed behind the center cross section in the front-to-rear direction of the cross section of the cuff rubber section 2. The elasticity of the rubber thread in the cuff rubber section 2 makes it possible to appropriately prevent the short socks 1 from slipping down. However, when walking or playing vigorous sports, the heel portion 7 of the short sock 1 often gets pulled toward the toes, causing it to slip down. However, the rear cuff rubber fastening portion 3 formed behind the front-to-back center cross section of the cuff rubber 2 acts to prevent the heel portion 7 of the short sock 1 from getting pulled toward the toes behind the cuff rubber 2 of the short sock 1 and slipping down. Therefore, the elasticity of the rear cuff rubber fastening portion 3, which is knitted with a lower elasticity than the cuff rubber 2, makes it difficult for the short sock 1 to slip down. In addition, because the rear cuff rubber fastening portion 3 is located behind the front-to-back center cross section of the cuff rubber 2, that is, near the rear of approximately the rear end of the lateral ankle portion 6a and approximately the rear end of the medial ankle portion 6b of the cuff rubber 2, the opening of the opening 5 is not tightened with a strong tightening force, and the opening 5 can be sufficiently widened when putting on the short sock 1, making it easy to put on. Furthermore, the rear cuff fastening section 3 is formed to a height from the top to the bottom of the cuff 2, so the rear cuff fastening section 3, which is knitted to a lower stretch rate than the cuff 2, has a sufficient height to prevent the sock from slipping down, making it even more difficult to slip down.

また、短靴下１には、上述したように、口ゴム部２の横断面の前後方向中央断面より後方で、その口ゴム部２の周方向に沿って形成された口ゴム後部締付部３が設けられているとともに、口ゴム部２の横断面の前後方向中央断面より後方で、装着時の踵骨９（図５参照）の後端と口ゴム部２の間から左右周方向に沿って口ゴム後部締付部３より横長さが長く形成された口ゴム後方下部締付部４を有している。そして、この口ゴム部２の横断面の前後方向中央断面より後方に形成された口ゴム後方下部締付部４は、口ゴム部２より伸縮率が低く編成された口ゴム後部締付部３とともに短靴下１の口ゴム部２後方で、短靴下１の踵部７付近が足先方向に引っ張られてずり落ちてしまうことを阻止するように作用するので、口ゴム後部締付部３とともに口ゴム後方下部締付部４の伸縮力により短靴下１がさらにずり落ちにくくすることができるとともに、口ゴム後方下部締付部４が口ゴム部２の横断面の前後方向中央断面より後方のみに設けられているので、履き口５の開口部も強い締付力で締め付けられず、短靴下１を履く際に履き口５を十分に広げることができ十分な履きやすさを有することができる。 As described above, the short sock 1 is provided with a rear cuff fastening portion 3 formed along the circumferential direction of the cuff rubber portion 2, rear of the central front-to-rear cross section of the cross section of the cuff rubber portion 2, and also has a rear lower cuff fastening portion 4 formed along the left-right circumferential direction from between the rear end of the calcaneus 9 (see Figure 5) when worn and the cuff rubber portion 2, rear of the central front-to-rear cross section of the cross section of the cuff rubber portion 2, with a horizontal length longer than the rear cuff fastening portion 3. The rear lower cuff fastening part 4, which is formed behind the center cross section of the cuff 2 in the front-to-back direction, works together with the rear cuff fastening part 3, which is knitted with a lower stretch rate than the cuff 2, to prevent the heel 7 of the short sock 1 from being pulled toward the toes behind the cuff 2 of the short sock 1 and slipping down. The stretching force of the rear lower cuff fastening part 4 together with the rear cuff fastening part 3 makes the short sock 1 even less likely to slip down. In addition, because the rear lower cuff fastening part 4 is only located behind the center cross section of the cuff 2 in the front-to-back direction, the opening of the opening 5 is not tightened with a strong tightening force, and the opening 5 can be sufficiently widened when putting on the short sock 1, making it easy to put on.

さらに、口ゴム後部締付部３が上辺が短く下辺が長い台形形状で形成され、口ゴム後方下部締付部４の上辺が口ゴム後部締付部３の下辺と同一長さで、下辺が上辺より長い台形形状で形成されている。そして、口ゴム後部締付部３および口ゴム後方下部締付部４の下辺が上辺より長い台形形状で形成しているので、下方の伸縮力が小さくなることによりさらにずり落ちにくくすることができる。また、口ゴム後部締付部３および口ゴム後方下部締付部４を上辺が下辺より短い台形形状で形成しているので、上方の伸縮力が下方の伸縮率より大きくなることにより十分な履きやすさを有することができる。 Furthermore, the rear fastening part 3 of the mouth rubber is formed in a trapezoid shape with a short top edge and a long bottom edge, and the top edge of the rear lower fastening part 4 of the mouth rubber is the same length as the bottom edge of the rear fastening part 3 of the mouth rubber, and is formed in a trapezoid shape with a longer bottom edge than the top edge. And because the bottom edges of the rear fastening part 3 of the mouth rubber and the rear lower fastening part 4 of the mouth rubber are formed in a trapezoid shape that is longer than the top edge, the downward stretching force is reduced, making it even less likely to slip down. Also, because the rear fastening part 3 of the mouth rubber and the rear lower fastening part 4 of the mouth rubber are formed in a trapezoid shape with the top edge shorter than the bottom edge, the upward stretching force is greater than the downward stretching force, making it sufficiently easy to wear.
