Description

[Technical Field]

[0001] The present invention relates to a limb attachment that covers part or all of a leg or arm. [Background technology]

[0002] In the past, "Thermal socks consisted of a main body and an opening portion, and were knitted on a B-type or K-type sock knitting machine with a cylinder diameter of 5 inches or more. The opening portion was knitted with 3 to 8 strands of 1 / 16 to 1 / 36 count wool-acrylic blended yarn or cotton yarn and rubber yarn with a sinker knitting technique in which 2 to 4 stitches were placed on every 1 or 2 pile stitches, and was constructed as a double structure. The outer layer of the double structure was curved so that the sinker knitting part was pulled by the rubber yarn and bulged outward, and the double structure The inner layer of the double-layered structure has a sinker-stitched knitted portion that is pulled by rubber yarn and curved so as to bulge inward, thereby making the opening thicker, and the terry-stitched portions of the outer and inner layers of the double-layered structure abut against each other, so that the sinker-stitched portions of the outer and inner layers repeatedly form a substantially closed thermal space in the circumferential direction (see, for example, Utility Model Registration No. 3166103 and JP 2012-122163 A). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3166103 [Patent Document 2] Japanese Patent Application Laid-Open No. 2012-122163 Summary of the Invention [Problem to be solved by the invention]

[0004] While the above-mentioned double-layered thermal legwear is useful in cold seasons such as winter, recently, other characteristics such as comfort as well as heat retention are required for such thermal legwear. The same is true for arm wearable devices such as arm warmers.

[0005] An object of the present invention is to provide a limb attachment that can impart properties other than heat retention without significantly impairing heat retention. [Means for solving the problem]

[0006] A limb wearing device according to a first aspect of the present invention is a limb wearing device that covers part or all of a limb and includes an inner knitted fabric layer and an outer knitted fabric layer. The term "limb" here refers to an arm or a leg. The term "leg" here refers to the region from the base of the thigh to the toes of the lower foot. The term "arm" here refers to the region from the base of the shoulder to the fingertips of the hand. The term "limb wearing device" refers to a device worn on at least one of the leg and the arm. This "limb wearing device" may include leg wearing devices that cover part or all of the leg, and arm wearing devices that cover part or all of the arm. When the limb wearing device is a leg wearing device, the leg wearing device may also include a device with a panty part. Examples of leg wearing devices include socks (socks, knee-high socks, etc.), leg warmers, stockings, and tights. Examples of arm wearing devices include arm covers, arm warmers, and long gloves. At least one first groove and one first rib are formed in the inner knitted fabric layer. This can also be expressed as the inner knitted fabric layer having striped concaves and convexes extending in one direction. The first groove extends toward the insertion opening on the outer side. Although the first groove is defined as "extending toward the insertion opening," this does not limit the formation direction of the first groove to being parallel to the tubular axis of the limb attachment. In other words, the formation direction of the first groove does not have to be parallel to the tubular axis of the limb attachment, as long as it does not deviate from the gist of the present invention. The insertion opening does not refer to a portion but to an edge. When the limb attachment is a leg attachment, the insertion opening is the opening. The first rib portion is provided adjacent to the first groove. At least one second groove and a second rib portion are formed in the outer knitted fabric layer. This can also be expressed as the outer knitted fabric layer having striped concaves and convexes extending in one direction. The second groove extends toward the insertion opening on the inner side. Although the second groove is defined as "extending toward the insertion opening," this does not mean that the direction in which the second groove is formed must be parallel to the cylindrical axis of the limb attachment. In other words, the direction in which the second groove is formed does not have to be parallel to the cylindrical axis of the limb attachment, as long as it does not deviate from the gist of the present invention. Note that the insertion opening does not refer to a part but to an edge. When the limb attachment is a leg attachment, the insertion opening is the opening.The second rib portion is provided adjacent to the second groove. The outer knitted fabric layer is disposed outside the inner knitted fabric layer. Here, the inner knitted fabric layer and the outer knitted fabric layer are knitted continuously in a tubular shape. The inner knitted fabric layer is folded back inside the outer knitted fabric layer so that its inner surface faces the inner surface of the outer knitted fabric layer. Here, the inner knitted fabric layer and the outer knitted fabric layer differ in at least part of their configuration.

[0007] As described above, the inner knitted fabric layer and the outer knitted fabric layer of the limb wearing device are knitted continuously in a tubular shape. The inner knitted fabric layer is folded inside the outer knitted fabric layer so that its inner surface faces the inner surface of the outer knitted fabric layer. Therefore, this limb wearing device can be knitted continuously on a knitting machine. Furthermore, in this limb wearing device, the inner knitted fabric layer and the outer knitted fabric layer have at least partial configurations that differ. Therefore, for example, (i) the inner knitted fabric layer and the outer knitted fabric layer are knitted so that all of the second grooves face all of the first grooves, and at least one of the thickness, number, composition, and stretchability of the yarns constituting the inner knitted fabric layer and the outer knitted fabric layer is different, or (ii) the inner knitted fabric layer and the outer knitted fabric layer are knitted so that at least some of the second grooves do not face the first grooves, thereby imparting properties other than heat retention (e.g., comfort, flexibility, stretchability, aesthetics, etc.) to the limb wearing device without significantly impairing its heat retention.

[0008] A limb wearing device according to a second aspect of the present invention is the limb wearing device according to the first aspect, wherein the inner knitted fabric layer and the outer knitted fabric layer are knitted so that all of the second grooves face all of the first grooves, and the inner knitted fabric layer and the outer knitted fabric layer differ in at least one of the thickness, number, composition, and stretchability of the constituent yarns.

[0009] Therefore, by adjusting the thickness, number, composition and elasticity of the yarns that make up the inner and outer knitted fabric layers, this limb attachment can be given properties other than heat retention without significantly impairing the heat retention properties of the limb attachment.

[0010] A limb wearing device according to a third aspect of the present invention is the limb wearing device according to the first aspect, wherein the inner knitted fabric layer and the outer knitted fabric layer are knitted so that at least some of the second grooves do not face the first grooves.

[0011] Therefore, this limb wearing device can stretch and contract in a width direction differently from the limb wearing device in which all the second grooves face all the first grooves, and therefore, when worn on a limb, it is expected that the limb wearing device can provide a different feeling of stretch and wearing sensation than a limb wearing device in which all the second grooves face all the first grooves.

[0012] A limb wearing device according to a fourth aspect of the present invention is the limb wearing device according to the third aspect, wherein the second grooves and second ridges are knitted to be formed at a formation pitch different from the formation pitch of the first grooves and first ridges.

[0013] When the above-mentioned knitting method is used, it is possible to knit a limb attachment in which some of the second grooves do not face the first grooves. Note that this knitting method also makes it possible to knit a limb attachment in which none of the second grooves face the first grooves.

[0014] A limb wearing device according to a fifth aspect of the present invention is the limb wearing device according to the third aspect, wherein the second groove is knitted to be formed at a position shifted from the position where the first groove is formed, and the second ridge is knitted to be formed at a position shifted from the position where the first ridge is formed.

[0015] When the above knitting method is used, it is possible to knit a limb attachment in which none of the second grooves faces any of the first grooves.

[0016] A limb wearing device according to a sixth aspect of the present invention is the limb wearing device according to the third to fifth aspects, further comprising a closing part. The closing part is formed on the insertion opening side of the inner knitted fabric layer. This closing part closes the insertion side ends of some or all of the first grooves. When the insertion opening side ends of all grooves are closed by the closing part, the heat retention of the limb wearing device can be improved. On the other hand, when the insertion opening side ends of some of the grooves are closed by the closing part, not only the heat retention can be improved but also stuffiness can be reduced.

[0017] Therefore, with this limb attachment, even when moving from a warm place to a cold place during cold season, the warm air contained in the grooves is less likely to escape, and cold air is less likely to enter the sock along the grooves from the outside. Therefore, this limb attachment does not cool the limb even in such situations.

[0018] A limb wearing device according to a seventh aspect of the present invention is the limb wearing device according to the sixth aspect, wherein at least one third ridge extending toward the insertion opening is formed on the inside of the closing portion, and some or all of the third ridge of the closing portion closes the insertion opening side ends of some or all of the first grooves.

[0019] The limb orthosis having the above-described structure can be knitted using a conventional knitting machine, and therefore can be manufactured without incurring equipment installation costs.

[0020] A limb wearing device according to an eighth aspect of the present invention is the limb wearing device according to any one of the first to seventh aspects, wherein the inner knitted fabric layer and the outer knitted fabric layer are knitted using pile sinker lay knitting.

[0021] Therefore, the limb orthosis can be manufactured using a conventional knitting machine, and therefore, the limb orthosis can be manufactured without incurring equipment installation costs.

[0022] A limb wearing device according to a ninth aspect of the present invention is the limb wearing device according to the eighth aspect, wherein in the inner knitted fabric layer and the outer knitted fabric layer, the elastic yarn is inserted into the knitted fabric by skipping stitches in pile sinker lay knitting.

[0023] Therefore, the limb orthosis can be manufactured using a conventional knitting machine, and therefore, the limb orthosis can be manufactured without incurring equipment installation costs. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0025] -First embodiment- <Configuration of knee socks according to the first embodiment of the present invention> Knee-high socks 100 according to the first embodiment of the present invention are knitted fabrics in a roughly V-shaped tube with one end (the end closest to the opening) open. These knee-high socks 100 were invented with the aim of keeping the legs warm and preventing them from getting cold.

[0026] 1 and 2, the knee socks 100 according to the first embodiment of the present invention are mainly composed of a foot-covering portion 110, a clamping portion 120, a connecting portion (not shown), and a partial leg-covering portion 130. These constituent parts will be described in detail below.

[0027] (1) Foot covering The foot-covering part 110 is a tubular part having a single knitted structure, and is a part for covering the wearer's foot. As shown in Figs. 1 and 2, one end of the foot-covering part 110 is closed, and the other end is connected to the clamping part 120. From the viewpoint of gently clamping the foot-covering part 110 to avoid discomfort, it is preferable that the foot-covering part 110 be knitted without plating the backing yarn (FTY). From the same viewpoint, it is also preferable that rubber yarn be inserted into the knitted fabric to give the knitted fabric stretchability.

[0028] (2) Clamping part The clamping portion 120 is a tubular portion having a single knit structure that covers the area slightly above the wearer's ankle and prevents the partial leg-covering portion 130 from shifting position (slipping down, etc.) when the knee-high socks 100 are worn. As shown in Figures 1 and 2, one end of the clamping portion 120 is connected to the foot-covering portion 110, and the other end is connected to the partial leg-covering portion 130. Also, as shown in Figures 1 and 2, a Sanyinjiao stimulating portion 122 is formed on the side of the clamping portion 120 at a position corresponding to the Sanyinjiao acupoint.

[0029] (3) Connection The connecting portion is a tubular portion having a single knitted structure, and serves to connect the clamping portion 120 and the inner knitted layer 130i of the partial leg covering portion 130.

[0030] (4) Partial leg covering The partial leg-covering portion 130 is a tubular portion having a double knitted structure, and when the knee-high socks 100 are worn, it covers the wearer's leg from above the ankle to slightly above the knee. That is, as shown in Figures 1, 3, and 4, this partial leg-covering portion 130 is made up of an inner knitted fabric layer 130i and an outer knitted fabric layer 130o. Below, the inner knitted fabric layer 130i and the outer knitted fabric layer 130o will each be described in detail.

[0031] (4-1) Inner knitted fabric layer The inner knitted fabric layer 130i is the layer that comes into contact with the skin when the knee-high socks 100 are worn, and as shown in Fig. 3, is mainly formed of a main body portion 131i and an opening portion 132i. One end of this inner knitted fabric layer 130i is connected to the pressing portion 120, and the other end is open and forms the opening of the knee-high socks 100. The inner knitted fabric layer 130i is knitted by inserting the elastic yarn Tr (see Fig. 4, etc.) into the knitted fabric with skipped stitches using pile sinker knitting.

[0032] (4-1-1) Main body The main body portion 131i is a rib knit fabric knitted by inserting the elastic yarn Tr into the knit fabric with skipped stitches using pile sinker knitting. This main body portion 131i has a plurality of rib portions Fi and grooves Gi formed along the wale direction, as shown in FIGS. 3 and 4. That is, in the main body portion 131i, a plurality of rib portions Fi and a plurality of grooves Gi are alternately arranged along the circumferential direction, as shown in FIGS. 3 and 4. Here, as shown in FIG. 4, the rib portions Fi are located on the inside and the grooves Gi are located on the outside. This main body portion 131i is preferably knitted using a sock knitting machine with a cylinder diameter of 3.5 inches or more, and more preferably with a sock knitting machine with a cylinder diameter of 5 inches or more. When the cylinder diameter of the knitting machine is relatively large, the diameter of the tubular knit fabric that constitutes the partial leg-covering portion 130 also becomes large, resulting in a loose fit even if the knee-high socks 100 are thick. It is preferable that main body portion 131i is brushed to improve the feel against the skin, because the brushed fibers fluff up, allowing main body portion 131i to contain a larger amount of air and have high heat retention, while also being soft and comfortable against the skin.

[0033] It is preferable that a yarn that feels good against the skin be used as the face yarn for knitting this main body portion 131i. Examples of yarns that feel good against the skin include spun yarns of rayon or acrylic, blended yarns in which rayon or acrylic is blended with other materials such as wool, short-staple spun yarns such as extra-long staple cotton yarns, and long-staple yarns such as nylon yarns and polyester yarns. High multifilament yarns are particularly preferable as long-staple yarns. Other examples of yarns that feel good against the skin include decorative twisted yarns such as mohair yarns and tam yarns. It is preferable that the total denier of this face yarn is in the range of 900 denier to 3000 denier.

[0034] Moreover, the main body portion 131i is preferably knitted so as not to be too thick, in order to give it a soft and smooth texture.

[0035] Furthermore, in order to knit this main body portion 131i as a rib knit fabric using pile sinker lay knitting, an elastic yarn Tr is used in addition to the face yarn. In one stitch, the elastic yarn Tr is inserted in the course direction between the sinker loop of a stitch made by the face yarn and the needle loop of a stitch made by the face yarn adjacent to that sinker loop in the wale direction. In another stitch, the elastic yarn Tr is inserted while skipping stitches in both the sinker loop of a stitch made by the face yarn and the needle loop of a stitch made by the face yarn adjacent to that sinker loop in the wale direction. A stitch in which the elastic yarn Tr is inserted between the sinker loop and the needle loop becomes a stitch that forms the groove Gi of the rib knit fabric, and a stitch in which the sinker loop and the needle loop are also skipped becomes a stitch that forms the rib portion Fi of the rib knit fabric. Here, the elastic yarn Tr is preferably inserted into the knitted fabric while skipping stitches within a range of 1 to 20 in the course direction, more preferably while skipping stitches within a range of 1 to 15 in the course direction, even more preferably while skipping stitches within a range of 1 to 10 in the course direction, even more preferably while skipping stitches within a range of 1 to 6 in the course direction, and even more preferably while skipping stitches within a range of 1 to 3 in the course direction. By skipping stitches within a range of 1 to 6 in the course direction with the elastic yarn Tr, the tubular diameter of the rib knitted fabric can be made to an appropriate thickness. Furthermore, by skipping stitches within a range of 1 to 3 in the course direction with the elastic yarn Tr, the rib knitted fabric can be given appropriate stretchability, which in turn allows the main body portion 131i to have an appropriate fit.

[0036] (4-1-2) Opening The opening 132i is disposed above the main body 131i. Like the main body 131i, the opening 132i is a rib knit fabric knitted by inserting the elastic yarn Tr into the fabric with skipped stitches using pile sinker knitting (see FIG. 3). Like the main body 131i, the opening 132i has multiple ribs Fi and grooves Gi formed along the wale direction. The positions and number of wales where the elastic yarn Tr is skipped in the opening 132i are the same as the positions and number of wales where the elastic yarn Tr is skipped in the main body 131i. That is, as shown in FIG. 3, the ribs Fi of the opening 132i are continuous with the ribs Fi of the main body 131i, and the grooves Gi of the opening 132i are continuous with the grooves Gi of the main body 131i. The denier and number of threads of the face yarn used to knit the opening portion 132i are different from the denier and number of threads of the face yarn used to knit the main body portion 131i.

[0037] (4-2) Outer knitted fabric layer The outer knitted fabric layer 130o is disposed on the outside of the inner knitted fabric layer 130i, as shown in Fig. 4. One end of this outer knitted fabric layer 130o is directly connected to the pressing portion 120, and the other end is connected to the upper end of the inner knitted fabric layer 130i. Like the inner knitted fabric layer 130i, this outer knitted fabric layer 130o is knitted by inserting the elastic yarn Tr into the fabric with skipped stitches in pile sinker lay knitting.

[0038] Similar to the inner knitted layer 130i, the outer knitted layer 130o has a plurality of rib portions Fo and grooves Go formed in the wale direction. As shown in Fig. 4, the positions and number of wales where the elastic yarn Tr is skipped in the outer knitted layer 130o are the same as the positions and number of wales where the elastic yarn Tr is skipped in the inner knitted layer 130i. Also, as shown in Fig. 4, the positions of the rib portions Fo in the outer knitted layer 130o coincide with the positions of the rib portions Fi in the inner knitted layer 130i, and the positions of the grooves Go in the outer knitted layer 130o coincide with the positions of the grooves Gi in the inner knitted layer 130i. In other words, the rib portions Fo in the outer knitted layer 130o are continuous with the rib portions Fi in the inner knitted layer 130i, and the grooves Go in the outer knitted layer 130o are continuous with the grooves Gi in the inner knitted layer 130i. As will be described later, this is due to the fact that the inner knitted fabric layer 130i is folded back to the inside of the outer knitted fabric layer 130o when knitting the knee-high socks 100. Furthermore, the denier and number of strands of the face yarn used to knit this outer knitted fabric layer 130o are the same as the denier and number of strands of the face yarn used to knit the opening portion 132i of the inner knitted fabric layer 130i, but are different from the denier and number of strands of the face yarn used to knit the main body portion 131i of the inner knitted fabric layer 130i.

[0039] For example, (i) the "total denier of the face yarns knitting the outer knitted layer 130o" is made larger than the "denier of the face yarns knitting the main body part 131i of the inner knitted layer 130i", (ii) the "number of face yarns knitting the outer knitted layer 130o" is made the same as the "number of face yarns knitting the main body part 131i of the inner knitted layer 130i", and the "denier per face yarn knitting the outer knitted layer 130o" is made the same as the "number of face yarns knitting the main body part 131i of the inner knitted layer 130i". (iii) the "denier per surface yarn knitting the outer knitted fabric layer 130o" is made larger than the "denier per surface yarn knitting the main body portion 131i of the inner knitted fabric layer 130i," and the "number of surface yarns knitting the outer knitted fabric layer 130o" is made larger than the "number of surface yarns knitting the main body portion 131i of the inner knitted fabric layer 130i." In this way, the height of the rib portion Fi in the inner knitted fabric layer 130i becomes lower than the height of the outer knitted fabric layer 130o. This makes it possible to make the inner knitted fabric layer 130i softer than the outer knitted fabric layer 130o. Furthermore, by sacrificing the softness of the inner knitted fabric layer 130i, the heat retention of the outer knitted fabric layer 130o can be improved.

[0040] Further, for example, (i) the "number of wales for skipping stitches of the elastic yarn Tr knitting the outer knitted layer 130o" is made larger than the "number of wales for skipping stitches of the elastic yarn Tr knitting the inner knitted layer 130i", (ii) the "contraction force of the elastic yarn Tr knitting the outer knitted layer 130o" is made larger than the "contraction force of the elastic yarn Tr knitting the inner knitted layer 130i", and (iii) the "feed amount of the elastic yarn Tr knitting the outer knitted layer 130o" is made smaller than the "feed amount of the elastic yarn Tr knitting the inner knitted layer 130i". In this way, the contraction force of the inner knitted layer 130i can be made weaker than the contraction force of the outer knitted layer 130o. As a result, the diameter of the outer knitted fabric layer 130o is smaller than the diameter of the inner knitted fabric layer 130i, making it less likely that the outer knitted fabric layer 130o and the inner knitted fabric layer 130i will become misaligned (slip down, etc.), improving the fit of the partial leg covering portion 130.

[0041] Further, for example, (i) the "number of wales for skipping stitches of the elastic yarn Tr knitting the outer knitted layer 130o" is made smaller than the "number of wales for skipping stitches of the elastic yarn Tr knitting the inner knitted layer 130i", (ii) the "contraction force of the elastic yarn Tr knitting the outer knitted layer 130o" is made smaller than the "contraction force of the elastic yarn Tr knitting the inner knitted layer 130i", and (iii) the "feed amount of the elastic yarn Tr knitting the outer knitted layer 130o" is made larger than the "feed amount of the elastic yarn Tr knitting the inner knitted layer 130i". In this way, the contraction force of the inner knitted layer 130i can be made stronger than the contraction force of the outer knitted layer 130o. As a result, the diameter of the outer knitted fabric layer 130o is larger than the diameter of the inner knitted fabric layer 130i, so that the amount of air between the outer knitted fabric layer 130o and the inner knitted fabric layer 130i increases, thereby improving the heat retention of the partial leg covering portion 130.

[0042] The total denier of the surface yarn and elastic yarn Tr used to knit the outer knitted fabric layer 130o is preferably in the range of 900 denier to 3000 denier. Examples of materials for the surface yarn include cotton, acrylic, nylon, polyester, animal hair (such as wool), ester, silk, acrylate polypropylene, and rayon. These surface yarns may be subjected to long fiber processing such as hollow processing, conjugate processing, and false twist processing. These surface yarns may be spun by a spinning method such as cotton spinning, worsted spinning, or woolen spinning. These surface yarns may also be subjected to design processing such as tam processing, bulky processing, ring processing, boucle processing, and mohair processing.

[0043] <Specific knitting method for knee socks according to the first embodiment of the present invention> As a knitting method for the knee socks 100 according to the first embodiment of the present invention, for example, the connecting portion 140 is knitted by knitting from the end of the connecting portion 140 on the pressing portion side to the end of the connecting portion 140 on the inner knitted fabric layer 130i side of the partial leg-covering portion 130, and then the main portion 131i is knitted by knitting from one end of the main portion 131i of the inner knitted fabric layer 130i of the partial leg-covering portion 130 to the end of the opening portion side of the main portion 131i, and then the denier and number of yarns of the face yarn are changed and then the main portion 131i is knitted from the end of the opening portion 132i of the inner knitted fabric layer 130i of the partial leg-covering portion 130 on the main portion side. Examples of such methods include knitting the opening portion 132i to the end of the outer knitted fabric layer side of the opening portion 132i, knitting the outer knitted fabric layer 130o from the opening end of the outer knitted fabric layer 130o to the end of the connection portion side of the outer knitted fabric layer 130o to knit the outer knitted fabric layer 130o, knitting the pressing portion 120 from the end of the partial leg covering portion side of the pressing portion 120 to the end of the foot covering portion side of the pressing portion 120 to knit the pressing portion 120, knitting from the end of the foot covering portion side of the pressing portion to the end of the foot covering portion 110 on the toe side, and finally folding the inner knitted fabric layer 130i back inside the outer knitted fabric layer 130o.

[0044] In the knitting method for these knee-high socks 100, the inner knitted layer 130i is preferably knitted so that the knit stitches on the needle loop side face inward, i.e., toward the skin, and the purl stitches on the sinker loop side face outward. Also, the outer knitted layer 130o is preferably knitted so that the knit stitches on the needle loop side face outward and the purl stitches on the sinker loop side face inward. In other words, the knee-high socks 100 are preferably knitted so that when the inner knitted layer 130i is folded back inward of the outer knitted layer 130o, the purl stitches of the outer knitted layer 130o face the purl stitches of the inner knitted layer 130i.

[0045] In addition to the method of inserting the elastic yarn Tr into the knitted fabric by skipping stitches in pile sinker knitting, methods for knitting the rib portions Fi and Fo include, for example, rib knitting, links knitting, rib knitting, rib knitting, and rib knitting. The rib portions Fi and Fo knitted in this manner are composed of knit stitches that are continuous in the wale direction and purl stitches that are continuous in the wale direction. This type of knitting can be performed on a double-cylinder knitting machine, such as a rib knitting machine or a links knitting machine. Another method for knitting the rib portions Fi and Fo is insertion knitting. In insertion knitting, a different yarn is inserted between knit stitches in the course direction. In a single-cylinder knitting machine, the elastic yarn Tr is inserted before and after the knit stitches, while in a double-cylinder knitting machine, the elastic yarn Tr is inserted between the knit stitches and purl stitches. In a single-cylinder knitting machine, a fabric with the elastic yarn Tr inserted is called an elastic rib.

[0046] <Features of the knee socks according to the first embodiment of the present invention> In the knee socks 100 according to the first embodiment of the present invention, the outer knitted fabric layer 130o has a plurality of rib portions Fo and grooves Go formed along the wale direction, similar to the inner knitted fabric layer 130i, and the denier and number of strands of the face yarn used to knit the outer knitted fabric layer 130o are the same as those of the face yarn used to knit the opening portion 132i of the inner knitted fabric layer 130i, but are different from those of the face yarn used to knit the main body portion 131i of the inner knitted fabric layer 130i. For this reason, (i) the "total denier of the face yarns knitting the outer knitted layer 130o" is made larger than the "denier of the face yarns knitting the main body portion 131i of the inner knitted layer 130i", (ii) the "number of face yarns knitting the outer knitted layer 130o" is made the same as the "number of face yarns knitting the main body portion 131i of the inner knitted layer 130i", and the "denier per face yarn knitting the outer knitted layer 130o" is made larger than the "denier per face yarn knitting the main body portion 131i of the inner knitted layer 130i", (iii) the "outer By making the "denier per surface yarn knitting the knitted fabric layer 130o" the same as the "denier per surface yarn knitting the main body portion 131i of the inner knitted fabric layer 130i," and by making the "number of surface yarns knitting the outer knitted fabric layer 130o" greater than the "number of surface yarns knitting the main body portion 131i of the inner knitted fabric layer 130i," it is possible to impart properties other than heat retention (for example, comfort, flexibility, stretchability, aesthetics, etc.) to the legwear without significantly impairing the heat retention of legwear such as knee-high socks. For example, by making the diameter of the outer knitted fabric layer 130o smaller than the diameter of the inner knitted fabric layer 130i, the outer knitted fabric layer 130o and the inner knitted fabric layer 130i are less likely to shift position (slip down, etc.), and the fit of the partial leg-covering portion 130 can be improved.

[0047] <Modification> (A) In the first embodiment, the present invention is applied to knee-high socks, but the present invention may also be applied to over-the-knee socks, leg warmers, stockings, tights, etc., and the present invention may also be applied to arm covers, arm warmers, etc. (B) In the knee socks 100 according to the first embodiment, the clamping portion 120 has a single-knit structure, but the clamping portion 120 may also have a double or more multi-knit structure. This allows an air layer to be formed between the layers, providing the clamping portion 120 with heat-retaining properties.

[0048] (C) The knee-high socks 100 according to the first embodiment were mainly composed of a foot-covering portion 110, a clamping portion 120, a connecting portion, and a partial leg-covering portion 130, but as long as the spirit of the invention is not impaired, the knee-high socks 100 may include other components. Also, the inner knitted fabric layer 130i of the partial leg-covering portion 130 was mainly composed of a main body portion 131i and an opening portion 132i, but as long as the spirit of the invention is not impaired, the inner knitted fabric layer 130i may include other components.

[0049] (D) In the knee socks 100 according to the first embodiment, the foot-covering parts 110 have a single-ply knitted structure, but the foot-covering parts 110 may have a double or more multi-ply knitted structure.

[0050] (E) In the knee socks 100 according to the first embodiment, the partial leg-covering portions 130 have a double knitted fabric structure, but the number of outer knitted fabric layers may be further increased to form a triple or more knitted fabric structure.

[0051] (F) Although the compression parts 120 are formed in the knee socks 100 according to the first embodiment, these compression parts 120 do not necessarily have to be formed.

[0052] (G) In the high socks 100 according to the first embodiment, a Sanyinjiao stimulating portion 122 was formed at a position corresponding to the Sanyinjiao acupoint on the side of the clamping portion 120, but this Sanyinjiao stimulating portion 122 does not have to be formed.

[0053] (H) When knitting the knee-high socks 100 according to the first embodiment, the inner knitted fabric layer 130i is folded back inside the outer knitted fabric layer 130o, but a separately knitted outer knitted fabric layer may be sewn to the inner knitted fabric layer 130i. Even in such a case, it is preferable to sew the outer knitted fabric layer to the inner knitted fabric layer 130i so that the purl stitches of the outer knitted fabric layer face the purl stitches of the inner knitted fabric layer 130i. In such a case, more freedom can be given to shifting the stitches of the outer knitted fabric layer relative to the inner knitted fabric layer 130i.

[0054] (I) In the knee-high socks 100 according to the first embodiment, the partial leg-covering portions 130 cover the wearer's legs from above the ankles to slightly above the knees when the knee-high socks 100 are worn, but the length and covering area of ​​the partial leg-covering portions 130 are not particularly limited, and for example, they may cover the wearer's legs from above the ankles to below the knees.

[0055] (J) In the knee socks 100 according to the first embodiment, the main body portion 131i and the opening portion 132i are provided on the inner knitted fabric layer 130i, but instead of or in addition to this, the main body portion and the opening portion may be provided on the outer knitted fabric layer 130o. Furthermore, when a main body portion and an opening portion are provided on both the inner knitted fabric layer 130i and the outer knitted fabric layer 130o, the yarn usage and knitting method may be different for each main body portion and / or each opening portion.

[0056] The above-described modifications may be adopted individually or in appropriate combinations within a range that does not cause any contradictions.

[0057] -Second embodiment- <Configuration of knee socks according to the second embodiment of the present invention> The knee-high socks according to the second embodiment of the present invention are identical to the knee-high socks 100 according to the first embodiment of the present invention, except for the partial leg-covering portions 130. For this reason, the same components as those in the knee-high socks 100 according to the first embodiment will be given the same reference numerals and their description will be omitted.

[0058] Like the partial leg-covering portion 130 according to the first embodiment, the partial leg-covering portion is a tubular portion having a double knitted structure, and when the knee-high socks are worn, covers the wearer's leg from above the ankle to slightly above the knee. That is, the partial leg-covering portion is made up of an inner knitted fabric layer 230i and an outer knitted fabric layer 230o (see FIG. 8). Below, the inner knitted fabric layer 230i and the outer knitted fabric layer 230o will each be described in detail.

[0059] (1) Inner knitted fabric layer Like the inner knitted fabric layer 130i according to the first embodiment, the inner knitted fabric layer 230i is a layer that comes into contact with the skin when the knee-high socks are worn, and is mainly formed of a main body portion 131i and an opening portion 232i, as shown in Fig. 5. Note that the main body portion 131i here is the same as the main body portion 131i according to the first embodiment, and is therefore given the same reference numeral as the knee-high socks 100 according to the first embodiment. For this reason, hereinafter, description of the main body portion 131i will be omitted, and only the opening portion 232i will be described.

[0060] The opening portion 232i is disposed on top of the main body portion 131i. The configuration of this opening portion 232i is similar to that of the main body portion 131i, but as shown in Figure 6, when knitting the opening portion 232i, a rib portion Fi2 of the opening portion 232i is formed in a position corresponding to the groove Gi of the main body portion 131i in the course direction, and a groove Gi2 of the opening portion 232i is formed in a position corresponding to the rib portion Fi of the main body portion 131i. Note that a person skilled in the art could knit this type of knitting without interruption, following on from the knitting of the main body portion 131i, simply by setting the parameters of the sock knitting machine, but it can also be done by switching yarns. When switching yarns during knitting of the opening portion 232i, a tightly knitted fabric can be knitted for the opening portion 232i using yarn with different stretch properties from that of the yarn for the main portion 131i. This increases the fit of the opening portion 232i to the skin of the leg and further blocks airflow to and from the grooves Gi of the main portion 131i. A knitted fabric knitted in this manner will have a shape as shown in FIG. 7. In FIG. 7, the symbol Dw indicates the wale direction, and the symbol Dc indicates the course direction. That is, the rib portion Fi2 of the opening portion 232i functions as a blocking portion that closes the opening-side end of the grooves Gi of the main portion 131i. This blocking portion can also be referred to as a ventilation shielding portion. The presence of this blocking portion prevents cold air from flowing into the groove Gi of the main body portion 131i from the outside, and also prevents warm air (air warmed by a person's legs) in the groove Gi of the main body portion 131i from escaping to the outside.

[0061] (2) Outer knitted fabric layer The outer knitted fabric layer 230o is disposed on the outside of the inner knitted fabric layer 230i, similar to the outer knitted fabric layer 130o according to the first embodiment. One end of this outer knitted fabric layer 230o is connected to the clamping portion 120, and the other end is connected to the upper end of the inner knitted fabric layer 230i. Similar to the inner knitted fabric layer 230i, this outer knitted fabric layer 230o is knitted by inserting the elastic yarn Tr into the fabric with skipped stitches in pile sinker lay knitting.

[0062] As shown in Fig. 8, this outer knitted layer 230o has a plurality of rib portions Fo2 and grooves Go2 formed in the wale direction, similar to the main body portion 131i of the inner knitted layer 130i. As shown in Fig. 8, the positions and number of wales where the elastic yarn Tr is skipped in this outer knitted layer 230o are the same as the positions and number of wales where the elastic yarn Tr is skipped in the main body portion 131i of the inner knitted layer 130i, but the stitches of the outer knitted layer 230o are shifted by one stitch in the course direction relative to the stitches of the main body portion 131i of the inner knitted layer 130i. As a result, as shown in Fig. 8, the rib portion Fo2 of the outer knitted layer 230o is located at a position corresponding to the groove Gi of the main body portion 131i, and the rib portion Fi of the main body portion 131i is located at a position corresponding to the groove Go2 of the outer knitted layer 230o. This is because, as will be described later, the inner knitted fabric layer is folded back inside the outer knitted fabric layer 230o when knitting the knee-high socks.

[0063] In addition, the relationship between "the total denier of the face yarns knitting the inner knitted layer, the number of face yarns, and the denier per face yarn" and "the total denier of the face yarns knitting the outer knitted layer, the number of face yarns, and the denier per face yarn" described in the section "(4-2) Outer knitted layer" of the first embodiment, and the relationship between "the number of wales for skipping stitches of the elastic yarn Tr knitting the inner knitted layer, the contraction force of the elastic yarn Tr, and the feed amount of the elastic yarn Tr" and "the number of wales for skipping stitches of the elastic yarn Tr knitting the outer knitted layer, the contraction force of the elastic yarn Tr, and the feed amount of the elastic yarn Tr" may also be applied to this outer knitted layer 230o.

[0064] <Specific knitting method for knee socks according to the second embodiment of the present invention> As a knitting method for knee socks according to an embodiment of the present invention, for example, knitting is performed by knitting the connecting portion 140 from the end of the connecting portion 140 on the pressing portion side to the end of the connecting portion 140 on the inner knitted fabric layer 130i side of the partial leg covering portion 130, knitting the main portion 131i by knitting from one end of the main portion 131i of the inner knitted fabric layer 230i of the partial leg covering portion to the end of the opening portion side of the main portion 131i, and then shifting the knitting position of the stitches where the elastic yarn is skipped, and knitting the main portion 131i from the end of the opening portion side of the main portion 232i of the inner knitted fabric layer 230i of the partial leg covering portion to the end of the opening portion side of the main portion 232i to the end of the outer knitted fabric layer side to knit the opening portion 232i, then knitting the outer knitted fabric layer 230o from the opening portion end of the outer knitted fabric layer 230o to the end of the connection portion side of the outer knitted fabric layer 230o to knit the outer knitted fabric layer 230o, further knitting the pressing portion 120 from the end of the partial leg covering portion side of the pressing portion 120 to the end of the foot covering portion side of the pressing portion 120 to knit the pressing portion 120, knitting from the end of the pressing portion side of the foot covering portion 110 to the end of the toe side of the foot covering portion 110, and finally folding the inner knitted fabric layer 230i back inside the outer knitted fabric layer 230o.

[0065] The method for knitting the rib portions Fi, Fi2, Fo2 is as explained above in the section <Specific knitting method for the knee-high socks according to the first embodiment of the present invention>.

[0066] <Features of the knee socks according to the second embodiment of the present invention> In the knee socks according to the second embodiment of the present invention, the stitches of the outer knitted layer 230o are offset by one stitch in the course direction relative to the stitches of the main body portion 131i of the inner knitted layer 230i. As a result, as shown in Fig. 8, the rib portion Fo2 of the outer knitted layer 230o is located at a position corresponding to the groove Gi of the main body portion 131i, and the rib portion Fi of the main body portion 131i is located at a position corresponding to the groove Go2 of the outer knitted layer 230o. As a result, in these knee socks, all of the grooves of the inner knitted layer can stretch and contract in the width direction differently from the legwear in which all of the grooves of the outer knitted layer face each other. Therefore, for example, when putting the legwear on a leg, it is expected that the legwear will provide a different sense of stretch and fit than legwear in which all of the grooves of the inner knitted layer face each other. Furthermore, these knee socks can prevent cold air from flowing into the grooves Gi of the main body 131i from the outside, and can also prevent warm air from inside the grooves Gi of the main body 131i from escaping to the outside. As a result, these knee socks have excellent heat insulation and heat retention properties.

[0067] <Modification> (A) In the second embodiment, the present invention is applied to knee-high socks, but the present invention may also be applied to over-the-knee socks, leg warmers, stockings, tights, etc., and the present invention may also be applied to arm covers, arm warmers, etc.

[0068] (B) In the knee socks according to the second embodiment, the rib Fi2 of the opening 232i is formed in a position corresponding to the groove Gi of the main body 131i, and the groove Gi2 of the opening 232i is formed in a position corresponding to the rib Fi of the main body 131i, and the rib Fi2 of the opening 232i functions as a closing portion that closes the end of the groove Gi of the main body 131i on the opening side, but the rib Fi2 of the opening 232i does not necessarily have to function as a closing portion. In other words, the rib Fi2 of the opening 232i may be formed so that the groove Gi of the main body 131i and the rib Fi2 of the opening 232i are connected to each other.

[0069] (C) In the knee socks according to the second embodiment, as shown in FIG. 6, the opening portion 232i is knitted one stitch away from the stitches of the main body portion 131i of the inner knitted fabric layer 130i in the course direction, so that a rib portion Fi2 of the opening portion 232i is formed at a position corresponding to the groove Gi of the main body portion 131i, and a groove Gi2 of the opening portion 232i is formed at a position corresponding to the rib portion Fi of the main body portion 131i. However, as shown in FIG. 9, the opening portion 332i may be knitted two stitches away from the main body portion 131i in the course direction, so that a rib portion Fi3 of the opening portion 332i is formed at a position corresponding to the groove Gi of the main body portion 131i, and a groove Gi3 of the opening portion 332i is formed at a position corresponding to the rib portion Fi of the main body portion 131i. Here, as long as the ridge portion Fi3 of the opening portion 332i is formed at a position corresponding to the groove Gi of the main body portion 131i, and the groove Gi3 of the opening portion 332i is formed at a position corresponding to the ridge portion Fi of the main body portion 131i, the number of shifted stitches is not particularly limited and can be set freely.

[0070] In this case, the positional relationship between the grooves Gi and rib portions Fi of the main body portion 131i and the grooves Go3 and rib portions Fo3 of the outer knitted fabric layer 330o is as shown in Fig. 10. This is because, as will be described later, the inner knitted fabric layer is folded back inside the outer knitted fabric layer 330o when knitting knee-high socks.

[0071] Furthermore, as shown in modification (B), the ridge Fi3 of the opening 332i may be formed so that the groove Gi of the main body 131i and the ridge Fi3 of the opening 332i communicate with each other.

[0072] (D) In the knee socks according to the second embodiment, as shown in FIG. 6, the opening portion 232i is knitted one stitch away from the stitches of the main body portion 131i of the inner knitted fabric layer 130i in the course direction, so that a rib portion Fi2 of the opening portion 232i is formed in a position corresponding to the groove Gi of the main body portion 131i, and a groove Gi2 of the opening portion 232i is formed in a position corresponding to the rib portion Fi of the main body portion 131i. However, as shown in FIG. 11, by knitting the opening portion 432i at a knitting pitch different from that of the main body portion 131i, a rib portion Fi4 of the opening portion 432i is formed in a position corresponding to the groove Gi of the main body portion 131i, and a groove Gi4 of the opening portion 432i is formed in a position corresponding to the rib portion Fi of the main body portion 131i. However, in this case, as shown in Figure 11, the position of some of the grooves Gi4 in the opening portion 432i coincides with the position of some of the grooves Gi in the main body portion 131i. This ensures that these knee-high socks are breathable without significantly compromising their heat insulation and heat retention properties. This means that these knee-high socks can prevent the wearer's legs from becoming sweaty.

[0073] In this case, the positional relationship between the grooves Gi and rib portions Fi of the main body portion 131i and the grooves Go4 and rib portions Fo4 of the outer knitted fabric layer 430o is as shown in Fig. 12. This is because, as will be described later, the inner knitted fabric layer is folded back inside the outer knitted fabric layer 430o when knitting knee-high socks.

[0074] Furthermore, as shown in modified example (B), the ridge Fi4 of the opening 432i may be formed so that the groove Gi of the main body 131i and the ridge Fi4 of the opening 432i communicate with each other.

[0075] (E) In the second embodiment, knee-high socks having the inner knitted fabric layer 230i shown in Fig. 5 were given as an example, but knee-high socks having the inner knitted fabric layer 530i shown in Fig. 13 may also be given as an example of an embodiment of the present invention. These knee-high socks are identical to the knee-high socks according to the second embodiment, except that the opening portion 232i in the inner knitted fabric layer 230i of the partial leg-covering portion according to the second embodiment is replaced with a closing portion 533i and an opening portion 532i. For this reason, only the closing portion 533i and the opening portion 532i of the inner knitted fabric layer 530i will be described in detail here.

[0076] When knitting the closing portion 533i, as when knitting the opening portion 232i of the knee-high socks of the second embodiment, a rib portion Fi6 of the closing portion 533i is formed in a position corresponding to the groove Gi of the main body portion 131i in the course direction, and a groove Gi6 of the closing portion 533i is formed in a position corresponding to the rib portion Fi of the main body portion 131i. Furthermore, when knitting the opening portion 532i, a rib portion Fi5 of the opening portion 533i is formed in a position corresponding to the groove Gi6 of the closing portion 533i in the course direction, and a groove Gi5 of the opening portion 532i is formed in a position corresponding to the rib portion Fi6 of the closing portion 533i. That is, in these knee-high socks, the groove Gi of the main body portion 131i is closed by the rib portion Fi6 of the closing portion 533i, and the groove Gi6 of the closing portion 533i is closed by the rib portion Fi5 of the opening portion 532i. Therefore, in these knee socks, the airtightness of the internal space of the groove Gi of the main body portion 131i can be further improved.

[0077] In addition, in these knee socks, (a) as shown in Figure 14, the closed portion 533i may be knitted two stitches apart from the stitches of the main body portion 131i in the course direction, and the opening portion 532i may be knitted two stitches apart from the stitches of the closed portion 533i, or (b) as shown in Figure 16, the closed portion 533i may be knitted one stitch apart from the stitches of the main body portion 131i in the course direction, and the knitting pitch of the opening portion 532i may be changed to be different from the knitting pitch of the closed portion 533i to knit the opening portion 532i, or (c) as shown in Figure 18, the knitting pitch of the closed portion 533i may be changed to be different from the knitting pitch of the main body portion 131i to knit the closed portion 533i, and the knitting pitch of the opening portion 532i may be changed to be different from the knitting pitch of the closed portion 533i to knit the closed portion 533i. Here, as long as a ridge portion Fi6 of the blocking portion 533i is formed at a position corresponding to the groove Gi of the main body portion 131i, a groove Gi6 of the blocking portion 533i is formed at a position corresponding to the ridge portion Fi of the main body portion 131i, and a ridge portion Fi5 of the opening portion 532i is formed at a position corresponding to the groove Gi6 of the blocking portion 533i, and a groove Gi5 of the opening portion 532i is formed at a position corresponding to the ridge portion Fi6 of the blocking portion 533i, the number of shifted stitches and the knitting pitch are not particularly limited and can be set freely.

[0078] Incidentally, when knitting these knee-high socks, after the opening portion 532i is knitted, the outer knitted layer 530o is knitted from the opening end of the outer knitted layer 530o to the end of the connecting portion side of the outer knitted layer 530o without changing the knitting position or knitting pitch, and when the inner knitted layer 530i is folded back inside the outer knitted layer 530o, in the knitting method (a) described above, The positional relationship between the grooves Go5 and rib portions Fo5 of the outer knitted fabric layer 530o is as shown in Figure 15, and in the knitting method of (b) above, the positional relationship between the grooves Gi and rib portions Fi of the main body portion 131i and the grooves Go5 and rib portions Fo5 of the outer knitted fabric layer 530o is as shown in Figure 17, and in the knitting method of (c) above, the positional relationship between the grooves Gi and rib portions Fi of the main body portion 131i and the grooves Go5 and rib portions Fo5 of the outer knitted fabric layer 530o is as shown in Figure 15. In the cases of (a) and (c) above, as shown in Figure 15, all of the grooves Gi of the main body portion 131i face all of the grooves Go5 of the outer knitted fabric layer 530o, and all of the rib portions Fi of the main body portion 131i face all of the rib portions Fo5 of the outer knitted fabric layer 530o. Therefore, in the above-mentioned cases (a) and (c), it is possible to make it difficult for air to move in the space between the main body portion 131i and the outer knitted fabric layer 530o, which is expected to result in improved heat retention.

[0079] Furthermore, as shown in variant example (B), the main body portion 131i, the blocking portion 533i and the opening portion 532i may be formed so that the groove Gi of the main body portion 131i, the groove Gi6 of the blocking portion 533i and the groove Gi5 of the opening portion 532i are connected (in such a case, the blocking portion 533i does not function as a blocking portion).

[0080] (F) When knitting the knee-high socks according to the second embodiment, the inner knitted fabric layer was folded inside the outer knitted fabric layer 230o, but a separately knitted outer knitted fabric layer may also be sewn to the inner knitted fabric layer. Even in such a case, it is preferable to sew the outer knitted fabric layer to the inner knitted fabric layer so that the purl stitches of the outer knitted fabric layer 230o face the purl stitches of the inner knitted fabric layer. Furthermore, in such a case, there is more freedom in shifting the stitches of the outer knitted fabric layer 230o relative to the inner knitted fabric layer.

[0081] (G) Although not specifically mentioned in the second embodiment, the contraction forces of the inner knitted fabric layer and the outer knitted fabric layer 230o may be adjusted. For example, if the contraction force of the outer knitted fabric layer 230o is made greater than that of the inner knitted fabric layer, the air layer between the inner knitted fabric layer and the outer knitted fabric layer 230o becomes narrower, improving the fit to the limbs. On the other hand, if the contraction force of the outer knitted fabric layer 230o is made smaller than that of the inner knitted fabric layer, the air layer between the inner knitted fabric layer and the outer knitted fabric layer 230o becomes wider, improving heat retention.

[0082] (H) In the knee socks according to the second embodiment, the inner knitted fabric layer 230i is provided with a main body portion 131i and an opening portion 232i, but instead of or in addition to this, the outer knitted fabric layer 230o may be provided with a main body portion and an opening portion. Furthermore, when a main body portion and an opening portion are provided in both the inner knitted fabric layer 230i and the outer knitted fabric layer 230o, the positional relationship between the grooves and ribs and the knitting pitch may be different for each main body portion and / or each opening portion. Furthermore, as shown in modified example (E), when the inner knitted fabric layer 530i is provided with a main body portion 131i, a closing portion 533i and an opening portion 532i, instead of or in addition to this, the outer knitted fabric layer 530o may be provided with a main body portion, a closing portion and an opening portion, and the positional relationship between the grooves and ribs and the knitting pitch may be different for each main body portion and / or each closing portion and / or each opening portion.

[0083] The above-mentioned modifications may be used alone or in appropriate combinations as long as there are no contradictions.Moreover, the modifications of the first embodiment may be applied to the knee socks according to the second embodiment. [Explanation of symbols]
