Description

Technical Field

[0001] The present invention relates to a blank for making boat socks from textile fabrics, boat socks made using the same, and a method for making boat socks using such a blank. Background Art

[0002] Generally, socks are articles made of various stretchable fabrics and worn on the feet, which can absorb water, keep warm, ventilate, etc. while protecting the feet from external impacts.

[0003] Socks come in various types according to their shape or length, such as ordinary socks that reach the lower part of the calf, knee socks, ankle socks, boat socks, toe socks, etc.

[0004] Recently, due to reasons such as fashion or convenience, various types of socks such as ankle socks and boat socks have been popular among consumers. In particular, boat socks are highly favored by many consumers because they are completely invisible when wearing shoes. Boat socks are also known as "fake socks".

[0005] Generally, socks are made by a sock knitting machine. The sock knitting machine installs needles on a needle cylinder. While the needle cylinder with the needles rotates, the multiple needles rise and fall in sequence along the needle grooves to weave a cylindrical sock. The conventional sock knitting machine as described above is configured to weave the curved part, neck part, heel, instep, bottom surface, and front side part of an ordinary sock into a cylindrical unit. However, according to the content described in Korean Patent No. 10-1178028, ultra-short socks (outer socks) or boat socks do not have an ankle part like ordinary socks, and the instep part is open. Therefore, it is very difficult to weave ultra-short socks or boat socks with a sock knitting machine configured as above, and thus it has become normal to make ultra-short socks or boat socks by sewing fabric materials.

[0006] However, when using this conventional method for making boat socks (or ultra-short socks), the bottom part, lid part, side lid part, heel part, etc. that make up the ultra-short socks or boat socks as shown in Figure 1 are connected to each other by sewing. Thus, since it is necessary to divide the boat socks into respective constituent parts and cut the fabric, and then sew them into constituent parts made of fabric pieces, the operation becomes cumbersome, and the fabric pieces of the constituent parts are mixed with each other, thereby reducing the operation efficiency.

[0007] As shown in Figure 2As shown, to solve such problems, Korean Utility Model Patent No. 20-0478268 discloses an ultra-short sock 500 that can be easily manufactured and can save labor costs or expenses by folding and sewing the toe part 520 and the heel part 530 relative to the bottom part 510 using a fabric made of a single piece.

[0008] In addition, Korean Patent No. 10-1632988 discloses a seamless ultra-short sock 600 made of a fabric composed of a single piece. As Figure 4 shown, the seamless ultra-short sock 600 described in Korean Patent No. 10-1632988 includes: a bottom part 610 composed of a bottom surface 611 having a shape similar to that of the sole of the foot and side covering units 612 extending from the bottom surface 611 to both sides and wrapping a part of the sides of the foot; and a covering part 620 composed of a front covering unit formed by extending from the front end of the bottom part 610 and having a width capable of covering a part of the instep including the toes. In addition, both side edges of the covering part 620 are adhered to both upper side edges of the side covering units 612 through a heat-melt layer, and the lower end edges 612a, 612b of the side covering units 612 are adhered to each other through a heat-melt layer.

[0009] However, as Figure 6A and Figure 6B shown, among the toes of a human foot, the big toe and / or the second toe generally have a longer shape than the other remaining toes (the third toe, the fourth toe, etc.). In contrast, as Figure 3 or Figure 5 shown, the front end part of the toe part of a conventional ultra-short sock is formed in a straight-line shape to match the part of the big toe and / or the second toe. Therefore, when wearing the ultra-short sock, the part of the big toe and / or the second toe is somewhat pressed, while the part of the little toe is relatively loose. As a result, there are problems that the shape of the foot wearing the ultra-short sock is not beautiful and the wearing feeling also deteriorates. In addition, due to friction with shoes, this conventional ultra-short sock is relatively easy to be damaged on the side stretched by the big toe or the second toe, so the durability of the ultra-short sock is poor and there is a problem of waste.

[0085] When the front portion 12 is folded along the boundary line BL toward the bottom face portion 10, the back surfaces 21B, 22B of the first overlapping portion 21 and the second overlapping portion 22 at the upper end of the front portion 12 are respectively arranged in a manner capable of overlapping with the front surfaces 23A of the third overlapping portion 23 at the upper end of the first side face portion 14 and the front surface 24A of the fourth overlapping portion 24 at the upper end of the second side face portion 16, and are sewn together at the upper and lower ends of the overlapping portion. Also, the edges 12a, 12b on both sides of the front portion 12 are respectively aligned in a manner capable of corresponding to the upper side edges 10a, 10b on both sides of the bottom face portion 10 and can be sewn together.

[0086] The fifth overlapping portion 25 at the lower end of the first side face portion 14 and the sixth overlapping portion 26 at the lower end of the second side face portion 16 overlap with each other and can be sewn together.

[0087] The ninth overlapping portion 29 at the lower end of the bottom face portion 10, the seventh overlapping portion 27 inside the first side face portion 14, and the eighth overlapping portion 28 inside the second side face portion 16 overlap with each other and can be sewn together.

[0088] Next, the boat sock 100 made using the blank 1 according to the first embodiment of the present invention will be described. In the description of the boat sock 100, the description of the parts that are repetitive with the description of the above blank 1 will be omitted.

[0089] According to the first embodiment of the present invention, the boat sock 100 made using the blank 1 composed of a textile fabric includes: a bottom face portion 10 forming a bottom surface composed of a series of textile fabrics connected integrally; a front portion 12 for covering the toes and the front instep; and a first side face portion 14 and a second side face portion 16 for wrapping the side of the foot and the heel respectively. The front portion 12 is connected to the upper end of the bottom face portion 10, as Figure 9A and Figure 9BAs shown, the boundary line BL formed by connecting the bottom surface portion 10 and the front portion 12 forms a prescribed inclination angle θ with respect to the horizontal line HL perpendicular to the central axis CL of the bottom surface portion 10. Among them, the inclination angle θ can be about 5° to 30°.

[0090] The shape of the toe part of a person varies from person to person, but in most cases, the big toe and / or the second toe are longer than the other remaining toes (the third toe, the fourth toe), and the little toe is the shortest. Generally, as Figure 6A and Figure 6B shown, the line (approximate tangent line) formed by connecting the front end portions of a person's toes forms a prescribed inclination angle with respect to the horizontal line perpendicular to the central axis of the sole. Therefore, the inclination angle θ formed by the boundary line BL formed by connecting the bottom surface portion 10 and the front portion 12 with respect to the horizontal line HL perpendicular to the central axis CL of the bottom surface portion 10 is set to about 5° to 30°. When the inclination angle θ is less than 5°, the part of the boat sock that contacts the big toe or the second toe will be somewhat pressed, which will not only make the shape of the foot wearing the boat sock unsightly, but also reduce the wearing feeling, and there is also a concern that the part contacting the big toe or the second toe is easily damaged. In addition, when the inclination angle θ is greater than 30°, there is more redundant space in the part of the boat sock where the big toe or the second toe is located, and thus the boat sock will be folded up, resulting in an unsightly shape of the foot wearing the boat sock and a decrease in the wearing feeling. Therefore, the inclination angle θ is set to about 5 to 30°.

[0091] In the boat sock 100 according to the first embodiment of the present invention, the fabrics of the bottom surface portion 10, the front portion 12, the first side surface portion 14, and the second side surface portion 16 for constituting each structural part of the boat sock can be fabrics woven by alternately providing elastic fiber filaments as weft filaments and warp filaments. The material of the fiber filaments for weaving the fabric can be merino wool, polyester, nylon, cotton, etc. When weaving the fabric, stretchable materials (for example, rayon or spandex filaments, etc.) can be appropriately mixed to obtain a fabric with better elasticity.

[0092] The boat sock 100 according to the first embodiment of the present invention, the bottom surface portion 10 has a contour corresponding to the sole of the foot, and a first side surface portion 14 and a second side surface portion 16 are respectively connected to two side surfaces on the lower side of the bottom surface portion 10. The lower end of the bottom surface portion 10 has a contour that bends and protrudes outward in a manner corresponding to the heel, and a ninth overlapping portion 29 may be formed at the lower end of the bottom surface portion 10; a third overlapping portion 23 may be formed at the upper end of the first side surface portion 14, and a first tangent line 31 extending to the lower end of the third overlapping portion 23 may be formed inside the third overlapping portion 23, and a fifth overlapping portion 25 may be formed at the lower end of the first side surface portion 14, and a seventh overlapping portion 27 may be formed inside the first side surface portion 14; a fourth overlapping portion 24 may be formed at the upper end of the second side surface portion 16, and a second tangent line 32 extending to the lower end of the fourth overlapping portion 24 may be formed inside the fourth overlapping portion 24, and a sixth overlapping portion 26 may be formed at the lower end of the second side surface portion 16, and an eighth overlapping portion 28 may be formed inside the second side surface portion 16; a first overlapping portion 21 and a second overlapping portion 22 may be formed at both sides of the upper end of the front portion 12, and the edges 12a, 12b on both sides of the front portion may have contours corresponding to the two side edges 10a, 10b on the upper side of the bottom surface portion 10; when the front portion 12 is folded along the boundary line BL relative to the bottom surface portion 10, the back surfaces 21B, 22B of the first overlapping portion 21 and the second overlapping portion 22 at the upper end of the front portion 12 are respectively arranged in a manner that can overlap with the front surface 23A of the third overlapping portion 23 at the upper end of the first side surface portion 14 and the front surface 24A of the fourth overlapping portion 24 at the upper end of the second side surface portion 16, and are sewn together at the upper and lower ends of the overlapping portion. Moreover, the two side edges 12a, 12b of the front portion are respectively aligned in a manner that can correspond to the two side edges 10a, 10b on the upper side of the bottom surface portion 10 and can be sewn together; the fifth overlapping portion 25 at the lower end of the first side surface portion 14 overlaps with the sixth overlapping portion 26 at the lower end of the second side surface portion 16 and can be sewn together; the ninth overlapping portion 29 at the lower end of the bottom surface portion 10 overlaps with the seventh overlapping portion 27 inside the first side surface portion 14 and the eighth overlapping portion 28 inside the second side surface portion 16 and can be sewn together.

[0093] With such a structure, when the front portion 12 is folded along the boundary line BL towards the bottom surface portion 10, as Figure 8AAs shown, the back surface 21B of the first overlapping portion 21 at the upper end of the front portion 12 is arranged to overlap with the front surface 23A of the third overlapping portion 23 at the upper end of the first side surface portion 14. Similarly, the back surface 22B of the second overlapping portion 22 at the upper end of the front portion 12 is arranged to overlap with the front surface 24A of the fourth overlapping portion 24 at the upper end of the second side surface portion 16. In this process, since the outer end portion 21c of the first overlapping portion 21 at the upper end of the front portion 12 is arranged inside the third overlapping portion 23 of the first side surface portion 14, and the outer end portion 22c of the second overlapping portion 22 at the upper end of the front portion 12 is arranged inside the fourth overlapping portion 24 of the second side surface portion 16, the upper end of the front portion 12 is easily bent outward and separated from the bottom surface portion 10, so that the boat sock can be made into a form that is easy to put the foot into. In addition, when the front portion 12 is folded along the boundary line BL toward the bottom surface portion 10, by aligning the outer end portion 21c of the first overlapping portion 21 of the front portion 12 with the first tangent line 31 of the first side surface portion 14, and aligning the outer end portion 22c of the second overlapping portion 22 of the front portion 12 with the second tangent line 32 of the second side surface portion 14, the first overlapping portion 21 and the second overlapping portion 22 of the front portion 12 can be accurately aligned with the third overlapping portion 23 and the fourth overlapping portion 24 of the bottom surface portion 10.

[0094] In addition, an adhesive may be coated between the back surface 21B of the first overlapping portion 21 of the front portion 12 and the front surface 23A of the third overlapping portion 23 of the first side surface portion 14, and between the back surface 22B of the second overlapping portion 22 of the front portion 12 and the front surface 24A of the fourth overlapping portion 24 of the second side surface portion 16. The adhesive may use a known adhesive that can bond fibers, leather, wood, etc. With such a structure, the bonding force between the first overlapping portion 21 and the third overlapping portion 23 and between the second overlapping portion 22 and the fourth overlapping portion 24 can be increased, and a temporary joint is formed between the first overlapping portion 21 and the third overlapping portion 23 and between the second overlapping portion 22 and the fourth overlapping portion 24, thereby improving the efficiency of the sewing operation.

[0095] In addition, as Figure 7A shown, a protrusion 12d protruding outward along the center line CL of the front portion 12 is formed at the center of the upper end portion of the front portion 12. By aligning the protrusion 12d on the center line CL of the bottom surface portion 10, the center of the upper end portion of the front portion 12 can be well aligned with the center of the bottom surface portion 10.

[0096] When the first overlapped portion 21 and the second overlapped portion 22 of the front portion 12 overlap with the third overlapped portion 23 of the first side portion 14 and the fourth overlapped portion 24 of the second side portion 16, respectively, the first overlapped portion 21 of the front portion 12 and the third overlapped portion 23 of the first side portion 14 can be sewn together in one row or more by seams, etc., and the second overlapped portion 22 of the front portion 12 and the fourth overlapped portion 24 of the second side portion 16 can be sewn together in one row or more by seams, etc. Since the joint portion between the first overlapped portion 21 of the front portion 12 and the third overlapped portion 23 of the first side portion 14 and the joint portion between the second overlapped portion 22 of the front portion 12 and the fourth overlapped portion 24 of the second side portion 16 are stress concentration sites, the joint strength is increased by sewing these parts in a "匚"-shaped sewing thread.

[0097] In addition, the side edges 12a, 12b of the front portion 12 may be aligned and sewn together in a manner corresponding to the side edges 10a, 10b of the upper side of the bottom portion 10. In this case, for example, one or more straight lines may be sewn using a sewing machine, and the edges may be finished by overlocking. In addition, one straight line sewing and overlocking may be performed simultaneously.

[0098] On the other hand, the fifth overlapped portion 25 at the lower end of the first side portion 14 and the sixth overlapped portion 26 at the lower end of the second side portion 16 for forming the rear heel portion of the boat socks overlap each other and can be sewn together. At this time, the ninth overlapped portion 29 at the lower end of the bottom portion 10 can overlap each other with the seventh overlapped portion 27 on the inner side of the first side portion 14 and the eighth overlapped portion 28 on the inner side of the second side portion 16, and can be sewn together. When sewing, a sewing machine can be used to perform more than one row of straight sewing, and the edge can also be finished with an overlock operation. In addition, one row of straight sewing and overlock operations can also be performed simultaneously.

[0099] In this case, a protrusion 29d protruding outward along the center line CL of the bottom portion 10 is formed at the center of the ninth overlapping portion 29 at the lower end of the bottom portion 10, so that the overlapping portion between the fifth overlapping portion 25 of the first side portion 14 and the sixth overlapping portion 26 of the second side portion 16 can be aligned on the center line CL of the bottom portion 10 at the lower end of the bottom portion 10, wherein the protrusion 29d can be formed as a reference point for arranging the overlapping portion between the fifth overlapping portion 25 and the sixth overlapping portion 26. By using such a reference point for finding the center, the efficiency of the sewing operation of the boat socks can be improved, and the phenomenon of poor product quality caused by misalignment can be prevented.

[0100] In the ankle sock 100 according to the first embodiment of the present invention, the boundary portion where the bottom surface portion 10 and the front portion 12 are connected is the portion in contact with the toes, and this portion is more likely to become fragile due to the friction of the toes than other portions, so it has a tendency to be worn out or damaged easily. Therefore, a reinforcing cloth 30 can be attached along the boundary line BL formed by connecting the bottom surface portion 10 and the front portion 12, thereby improving the durability of the ankle sock. Generally, the fabric of the ankle sock is set such that the elongation rate in the longitudinal direction (the direction of the selvage) is greater than the elongation rate in the lateral direction (the direction of the cut edge), so that it can be more easily elongated in the length direction of the foot. The reinforcing cloth 30 attached to the ankle sock 100 according to the first embodiment of the present invention can be set such that the elongation rate in its longitudinal direction (the direction of the selvage) is greater than the elongation rate in the lateral direction (the direction of the cut edge). Although the elongation rate in the longitudinal direction (the direction of the selvage) of the fabric of the ankle sock is even greater than the elongation rate in the lateral direction (the direction of the cut edge), when the elongation rate in the longitudinal direction (the direction of the selvage) of the reinforcing cloth is less than the elongation rate in the lateral direction (the direction of the cut edge), a tight and dull feeling will be felt in the part of the big toe or the second toe, thus reducing the wearing comfort of the ankle sock. Therefore, in order to obtain a comfortable wearing feeling, it is preferable to set the elongation rate in the longitudinal direction (the direction of the selvage) of the reinforcing cloth 30 to be greater than the elongation rate in the lateral direction (the direction of the cut edge), so that the fabrics of the ankle sock and the reinforcing cloth can have substantially equal elongation rates in the same direction.

[0101] The material of the reinforcing cloth 30 can also be the same material as that of the ankle sock 100, or other materials with stronger durability than the ankle sock.

[0102] Since the ankle portion of a general sock is formed to be narrow, the ankle portion of the sock will tightly wrap around and grip the ankle of the sock wearer, so the sock is not easily taken off. In contrast, for an ankle sock, the opening of the sock is relatively larger than that of a general sock, so the force to wrap around and grip the instep of the wearer is weaker, and thus the opening portion of the ankle sock has a tendency to be stretched open. To improve these problems, as Figure 10 shown, elastic bands 40 can be attached to the upper edge of the front portion 12 and the edges of the first side surface portion 14 and the second side surface portion 16 of the ankle sock respectively. Such an elastic band 40 can be, for example, a highly elastic band in a strip shape made by winding a plurality of rubber bands with a fabric material. By attaching the elastic bands 40, a contracting force is applied to the opening of the ankle sock, so that the opening of the ankle sock can stably adhere to the instep of the wearer.

[0103] In addition, in the ankle sock 100 according to the first embodiment of the present invention, a friction member 50 made of silicone material may be attached to the outside of the overlapping portion between the fifth overlapping portion 25 of the first side surface portion 14 and the sixth overlapping portion 26 of the second side surface portion 16. In addition, a friction member 50 made of silicone material may be attached to the portion corresponding to the heel among the edges of the first side surface portion 14 and the second side surface portion 16. With such a structure, in the ankle sock 100, as shown in the lower right end of Figure 10 the "T"-shaped friction member 50 made of silicone material may be disposed at the inner portion in contact with the heel, and the friction member 50 contacts the wearer's heel horizontally and vertically, thereby improving the wearing stability of the ankle sock and preventing the phenomenon that the ankle sock is removed together when taking off shoes by increasing the friction force between the ankle sock and the heel.

[0104] Next, according to the first embodiment of the present invention, a method for manufacturing the ankle sock 100 using a textile fabric will be described. When describing the manufacturing method of the ankle sock 100, the description of the parts repeated from the above description of the blank 1 and the ankle sock 100 will be omitted.

[0105] First, a fabric made of an elastic material is cut into the form of the blank 1 as shown in Figure 7A (a single-piece manner) (step S10).

[0106] In this case, in a state where multiple (for example, about 100 sheets) textile fabrics having a specified width × height specification (for example, a width of about 150 cm × a height of about 300 cm) are stacked, a template (marker) (not shown) made in the same shape as the blank 1 is placed on the upper surface of the textile fabric, and then the multiple textile fabrics are cut into the same shape as the template by a cutting machine, thereby manufacturing multiple blanks 1. The textile fabric may be a fabric woven by alternately arranging elastic fiber filaments as weft filaments and warp filaments.

[0107] Figure 7A The blank 1 shown in includes: a bottom surface portion 10, forming a bottom composed of a series of textile fabrics connected integrally; a front portion 12, for covering the toes and the front instep; and a first side surface portion 14 and a second side surface portion 16, respectively for wrapping the side of the foot and the heel. And, the front portion 12 is connected to the upper end of the bottom surface portion 10, and the boundary line BL formed by connecting the bottom surface portion 10 and the front portion 12 forms a specified inclination angle with respect to the horizontal line HL perpendicular to the central axis CL of the bottom surface portion 10. Among them, the inclination angle θ may be about 5° to 30°.

[0108] Thereafter, the front portion 12 of the blank 1 is folded relative to the bottom surface portion 10 along a boundary line BL formed by connecting the front portion 12 and the bottom surface portion 10 (step S20 ).

[0109] Afterwards, the outer end 21c of the first overlapping portion 21 of the front portion 12 is aligned with the first tangent 31 of the first side portion 14, so that the back side 21B of the first overlapping portion 21 of the front portion 12 can overlap with the front side 23A of the third overlapping portion 23 of the first side portion 14, and the outer end 22c of the second overlapping portion 22 of the front portion 12 is aligned with the second tangent 32 of the second side portion 14, so that the back side 22B of the second overlapping portion 22 of the front portion 12 can overlap with the front side 24A of the fourth overlapping portion 24 of the second side portion 16 (step S30).

[0110] Afterwards, the first overlapped portion 21 of the front portion 12 and the third overlapped portion 23 of the first side portion 14 are sewn into one or more rows, and the second overlapped portion 22 of the front portion 12 and the fourth overlapped portion 24 of the second side portion 16 are sewn into one or more rows, and the side edges 12a, 12b of the front portion 12 and the side edges 10a, 10b of the upper side of the bottom portion 10 are sewn into one or more rows (step S40). Among them, the joint between the first overlapped portion 21 of the front portion 12 and the third overlapped portion 23 of the first side portion 14 and the joint between the second overlapped portion 22 of the front portion 12 and the fourth overlapped portion 24 of the second side portion 16 are stress concentration sites, and by sewing these parts, the sewing line is formed into a "匚" shape, thereby increasing the bonding force.

[0111] Thereafter, the fifth overlapping portion 25 at the lower end of the first side portion 14 and the sixth overlapping portion 26 at the lower end of the second side portion 16 are overlapped with each other and sewn in one or more rows (step S50 ).

[0112] Then, the ninth overlapping portion 29 at the lower end of the bottom portion 10 is overlapped with the seventh overlapping portion 27 inside the first side portion 14 and the eighth overlapping portion 28 inside the second side portion 16, and sewn into one or more rows (step S60).

[0113] In the method for manufacturing the boat socks 100 according to the modified example of the first embodiment of the present invention, a plurality of blanks 100 are cut through the process of step S10, and then the following process may be selectively performed before performing the process of step S20.

[0114] An elastic band 40 is temporarily joined (performing the initial operation) at the upper edge of the front portion 12, the edge of the first side portion 14, and the edge of the second side portion 16 of the blank 1 respectively, or a reinforcing cloth 30 with a specified vertical height is temporarily joined along the boundary line BL formed by connecting between the bottom portion 10 and the front portion 12, and a hot pressing operation (an operation of applying heat while applying pressure) can be performed on the temporarily joined portion of the elastic band 40 and / or the temporarily joined portion of the reinforcing cloth 30 (step S70). In this case, the reinforcing cloth 30 can be arranged such that the elongation rate in the longitudinal direction (cloth edge direction) is greater than the elongation rate in the transverse direction (seam opening direction). Additionally, a friction member 50 made of silicone material can be attached in a "T" shape at the portion corresponding to the heel in the ankle socks (step S80). In this case, instead of attaching the friction member 50 made of silicone material, silicone can also be coated or laminated at the portion corresponding to the heel in the ankle socks.

[0115] For the sock produced by the manufacturing method of the ankle sock 100 according to the first embodiment of the present invention as described above, by turning the sock inside out to make the sewing line, the reinforcing cloth, the elastic band, the silicone friction member, etc. located inside the ankle sock, and then wearing the sock.

[0116] (Second Embodiment)

[0117] Next, with reference to Figures 11 to 13 , the blank 2 for making an ankle sock from a textile fabric according to the second embodiment of the present invention, the ankle sock 200 made using such a blank 2, and its manufacturing method will be described. The structures and functions of the blank 2 for making an ankle sock from a textile fabric, the ankle sock 200, and its manufacturing method according to the second embodiment will be described with the parts different from those of the first embodiment as the focus.

[0118] When comparing the blank 2 for making an ankle sock from a textile fabric and the ankle sock 200 according to the second embodiment with the blank 1 and the ankle sock 100 according to the first embodiment, in the first embodiment, since the front portion 12 wraps the sides of the toes and the front foot, the connecting line (for example, a sewing line or a heat fusion bonding line, etc.) of the portion where the front portion 12 is combined with the bottom portion 10 is located on the lower side of the toes and the front foot, thus generating a different foreign body sensation from the contact with the fabric of the ankle sock. In contrast, in the second embodiment, since the first side portion 214 and the second side portion 216 wrap the sides of the toes and the front foot, the connecting line (for example, a seam sealing portion, etc.) of the portion where the front portion 212 is combined with the bottom portion 210 is located on the upper side of the toes and the front foot, so that a different foreign body sensation from the contact with the fabric of the ankle sock can be removed, and there is a difference in this regard. With this structure, the wearing feeling of the ankle sock can be improved.

[0119] In addition, in the blank 1 and the ankle sock 100 according to the first embodiment, both side edges 12a and 12b of the front portion 12 are sewn together with the corresponding both side edges 10a and 10b of the bottom portion 10, and the first overlapping portion 21 and the second overlapping portion 22 at the upper end of the front portion 12 are respectively sewn together with the third overlapping portion 23 at the upper end of the first side portion 14 and the fourth overlapping portion 24 at the upper end of the second side portion 16. In contrast, in the blank 2 and the ankle sock 200 according to the second embodiment, since both side edges 212a and 212b of the front portion 212 are respectively sewn and sealed together with the upper side edge 214a of the first side portion 214 and the upper side edge 216b of the second side portion 216, there is a difference in that there is no sewing thread at the portion in the ankle sock that contacts the front instep.

[0120] Except for the above two differences, the structure and function are substantially similar to those of the blank 1 and the ankle sock 100 according to the first embodiment.

[0121] According to Figure 11 The blank 2 for making an ankle sock from a textile fabric according to the second embodiment of the present invention as shown in

[0122] The first side portion 214 and the second side portion 216 may be respectively connected to both sides of the bottom portion 210.

[0123] Both side edges 212a and 212b of the front portion may respectively have contours corresponding to the upper side edge 214a of the first side portion 214 and the upper side edge 216b of the second side portion 216.

[0124] When the front part 212 is folded along the boundary line BL towards the bottom part 210, the two side edges 212a and 212b of the front part 212 are aligned with the upper side edge 214a of the first side part 214 and the upper side edge 216b of the second side part 216 respectively, and can be sewn and sealed together. In this case, instead of the sewing and sealing operation, a hot melt operation in the prior art can also be used, and the detailed description thereof will be omitted.

[0125] Next, the boat sock 200 made from the blank 2 according to the second embodiment of the present invention will be described. When the boat sock 200 is described, the description of the parts that are repeated with the description of the blank 2 will be omitted.

[0126] According to the second embodiment of the present invention, the boat sock 200 made from the blank 2 composed of a textile fabric includes: a bottom part 210, which is composed of a series of textile fabrics connected integrally and has a contour corresponding to the sole of the foot, and forms the bottom surface of the boat sock; a front part 212, which has a contour corresponding to the toes and the front instep; and a first side part 214 and a second side part 216, which are respectively used to wrap the side of the foot and the heel. The front part 212 is connected to the upper end of the bottom part 210, and as Figure 11 shown, the boundary line BL formed by the connection between the bottom part 210 and the front part 212 forms a specified inclination angle θ with respect to the horizontal line HL perpendicular to the central axis CL of the bottom part 210.

[0127] Among them, the inclination angle θ can be about 5° to 30°. When the inclination angle is less than 5°, the part in the boat sock that contacts the big toe or the second toe will be somewhat pressed, which will not only make the shape of the foot wearing the boat sock unsightly and reduce the wearing feeling, but also there is a concern that the part in contact with the big toe or the second toe is easily damaged. In addition, when the inclination angle is greater than 30°, there is too much extra space in the part of the boat sock where the big toe or the second toe is located, and thus the boat sock will be folded up, resulting in an unsightly shape of the foot wearing the boat sock and a decrease in the wearing feeling.

[0128] In the ankle sock 200 according to the second embodiment of the present invention, the materials of the bottom surface portion 210, the front portion 212, the first side surface portion 214, and the second side surface portion 216 of the respective structural portions constituting the ankle sock may be fabrics woven by alternately arranging elastic weft yarns and warp yarns. The materials of the fiber filaments for weaving the fabrics may be merino wool, polyester, nylon, cotton, etc. When weaving the fabrics, stretchable materials (e.g., rayon or spandex filaments, etc.) may be appropriately mixed to obtain fabrics with good elasticity.

[0129] In the ankle sock 200 according to the second embodiment of the present invention, the first side surface portion 214 and the second side surface portion 216 are respectively connected to both sides of the bottom surface portion 210, and the lower end of the bottom surface portion 210 has a contour that bends and protrudes outward in a manner corresponding to the heel, and a ninth overlapping portion 229 is formed at the lower end of the bottom surface portion 210; a fifth overlapping portion 225 is formed at the lower end of the first side surface portion 214, and a seventh overlapping portion 227 is formed on the inner side of the first side surface portion 214; a sixth overlapping portion 226 is formed at the lower end of the second side surface portion 216, and an eighth overlapping portion 228 is formed on the inner side of the second side surface portion 216; the two side edges 212a, 212b of the front portion 212 respectively have contours corresponding to the upper side edges 214a of the first side surface portion 214 and the upper side edges 216b of the second side surface portion 216; when the front portion 212 is folded relative to the bottom surface portion 210 along the boundary line BL, the two side edges 212a, 212b of the front portion 212 are respectively aligned in a manner consistent with the upper side edges 214a of the first side surface portion 214 and the upper side edges 216b of the second side surface portion 216, and can be sewn and sealed together. In this case, since the end portions where the two side edges 212a, 212b of the front portion 212 are sewn and sealed with the upper side edges 214a of the first side surface portion 214 and the upper side edges 216b of the second side surface portion 216 are stress concentration sites, as Figure 12B shown in, a bar tack 260 for tightly sewing this end portion can be formed. Such a bar tack 260 can be formed in the same color as the ankle sock 200, and can also be formed in other colors, making it a design highlight of the ankle sock 200.

[0130] In addition, a fifth overlapping portion 225 at the lower end of the first side surface portion 214 and a sixth overlapping portion 226 at the lower end of the second side surface portion 216 overlap with each other and can be sewn together; a ninth overlapping portion 229 at the lower end of the bottom surface portion 210, a seventh overlapping portion 227 inside the first side surface portion 214, and an eighth overlapping portion 228 inside the second side surface portion 216 overlap with each other and can be sewn together.

[0131] In addition, as Figure 11 shown, a protrusion 212d protruding outward along the center line CL of the front portion 212 is formed at the center of the upper end portion of the front portion 212. By aligning the protrusion 212d on the center line CL of the bottom surface portion 210, the center of the upper end portion of the front portion 212 can be well aligned with the center of the bottom surface portion 210.

[0132] On the other hand, a fifth overlapping portion 225 at the lower end of the first side surface portion 214 and a sixth overlapping portion 226 at the lower end of the second side surface portion 216 that form the heel portion of the boat sock overlap with each other and can be sewn together. At this time, a ninth overlapping portion 229 at the lower end of the bottom surface portion 210, a seventh overlapping portion 227 inside the first side surface portion 214, and an eighth overlapping portion 228 inside the second side surface portion 216 overlap with each other and can be sewn together. During the sewing operation, it can be sewn into more than one row of straight lines using a sewing machine, and its edges can also be finished with an overlocking process. In addition, a row of straight-line sewing and an overlocking operation can be performed simultaneously.

[0133] In this case, a protrusion 229d protruding outward along the center line CL of the bottom surface portion 210 is formed at the center of the ninth overlapping portion 229 at the lower end of the bottom surface portion 210. Thereby, at the lower end of the bottom surface portion 210, the overlapping portion between the fifth overlapping portion 225 of the first side surface portion 214 and the sixth overlapping portion 226 of the second side surface portion 216 can be aligned on the center line CL of the bottom surface portion 210, and the protrusion 229d can be formed as a reference point for arranging the overlapping portion between the fifth overlapping portion 225 and the sixth overlapping portion 226. By using this center-finding reference point, the efficiency of the sewing operation of the boat sock can be improved, and the quality degradation phenomenon of the product that may be caused by alignment errors can be prevented.

[0134] In the ankle sock 200 according to the second embodiment of the present invention, the boundary portion where the bottom surface portion 210 and the front portion 212 are connected is the portion that comes into contact with the toes, and this portion is more likely to become fragile due to toe friction compared to other portions, and thus has a tendency to be worn or damaged easily. Therefore, a reinforcing cloth 230 can be attached along the boundary line BL formed by connecting the bottom surface portion 210 and the front portion 212, thereby improving the durability of the ankle sock.

[0135] Generally, the fabric of the ankle sock is set such that the elongation rate in the longitudinal direction (the direction of the selvage) is greater than the elongation rate in the transverse direction (the direction of the cut edge), so that it can be more easily elongated in the length direction of the foot. The reinforcing cloth 230 attached in the ankle sock 200 according to the second embodiment of the present invention can be set such that its elongation rate in the longitudinal direction (the direction of the selvage) is greater than the elongation rate in the transverse direction (the direction of the cut edge). Although the elongation rate of the fabric of the ankle sock in the longitudinal direction (the direction of the selvage) is even greater than the elongation rate in the transverse direction (the direction of the cut edge), when the elongation rate of the reinforcing cloth in the longitudinal direction (the direction of the selvage) is less than the elongation rate in the transverse direction (the direction of the cut edge), the area of the big toe or the second toe will feel tight and dull, thus reducing the wearing comfort of the ankle sock. Therefore, in order to obtain a comfortable wearing feeling, it is preferable to set the elongation rate of the reinforcing cloth 230 in the longitudinal direction (the direction of the selvage) to be greater than the elongation rate in the transverse direction (the direction of the cut edge), so that the fabrics of the ankle sock and the reinforcing cloth can have substantially equal elongation rates in the same direction.

[0136] The material of the reinforcing cloth 230 can be the same material as that of the ankle sock 200, or other materials with stronger durability than the ankle sock.

[0137] In addition, as Figure 13 shown, elastic bands 240 can be attached respectively to the upper edge of the front portion 212 of the ankle sock, the lower edge of the first side surface portion 214, and the lower edge of the second side surface portion 216. By attaching such elastic bands 240, a contracting force is applied to the opening portion of the ankle sock, so that the opening portion of the ankle sock can stably adhere to the instep of the wearer.

[0138] In addition, in the ankle sock 200 according to the second embodiment of the present invention, a friction member 250 made of silicone material can be attached to the outside of the overlapping portion between the fifth overlapping portion 225 of the first side surface portion 214 and the sixth overlapping portion 226 of the second side surface portion 216. In addition, a friction member 250 made of silicone material can be attached to the portion corresponding to the heel in the edges of the first side surface portion 214 and the second side surface portion 216. With such a structure, in the ankle sock 200, as Figure 13As shown in the lower right side of [], the friction member 250 made of silicone in a "T" shape can be arranged at the inner part in contact with the heel, and the friction member 250 contacts the wearer's heel horizontally and vertically, so as to improve the stability of wearing the ankle sock, and prevent the phenomenon that the ankle sock is taken off together when taking off shoes by increasing the friction between the ankle sock and the heel.

[0139] Next, according to the second embodiment of the present invention, a method for manufacturing the ankle sock 200 with a textile fabric will be described. When describing the manufacturing method of the ankle sock 200, the description of the parts that are repeated with the above description of the blank 2 and the ankle sock 200 will be omitted.

[0140] First, a fabric of an elastic material is cut into the form of the blank 2 as shown in Figure 11 (step S210).

[0141] In this case, in a state where multiple (for example, about 100 sheets) of textile fabrics with a specified width × height specification (for example, a width of about 150 cm × a height of about 300 cm) are stacked, a template (marker) (not shown) made in the same shape as the blank 2 is placed on the upper surface of the textile fabric, and then a cutting machine is used to make multiple blanks 2 in the same shape as the template (step S210).

[0142] As shown in Figure 11 the blank 2 includes: a bottom surface portion 210, which is composed of a series of textile fabrics connected integrally, has a contour corresponding to the sole of the foot, and forms the bottom surface of the ankle sock; a front portion 212, which has a contour corresponding to the toes and the front instep; and a first side surface portion 214 and a second side surface portion 216, which are respectively used to wrap the side of the foot and the heel, and the front portion 212 is connected to the upper end of the bottom surface portion 210, and a boundary line BL formed by connecting between the bottom surface portion 210 and the front portion 212 forms a specified inclination angle θ with respect to a horizontal line HL perpendicular to the central axis CL of the bottom surface portion 210. Among them, the inclination angle θ can be about 5° to 30°.

[0143] After that, the front portion 212 of the blank 2 is folded along the boundary line BL formed by connecting between the front portion 212 and the bottom surface portion 210 with respect to the bottom surface portion 210 (step S220).

[0144] After that, both side edges 212a and 212b of the front portion 212 are aligned with the upper edge 214a of the first side face portion 214 and the upper edge 216b of the second side face portion 216, respectively, and can be sewn and sealed together (Seam sealing) (step S230). In this case, instead of the sewing and sealing operation, a hot melt operation in the prior art can also be used. Since the end portions where both side edges 212a and 212b of the front portion 212 are sewn and sealed with the upper edge 214a of the first side face portion 214 and the upper edge 216b of the second side face portion 216 are stress concentration portions, as shown in Figure 12B as shown, a bar tack 260 for tightly sewing the end portion can be formed. Such a bar tack 260 can be formed in the same color as the color of the ankle sock 200, and can also be formed in other colors.

[0145] After that, the fifth overlapping portion 225 at the lower end of the first side face portion 214 and the sixth overlapping portion 226 at the lower end of the second side face portion 216 are overlapped with each other and sewn into more than one row (step S240).

[0146] After that, the ninth overlapping portion 229 at the lower end of the bottom face portion 210, the seventh overlapping portion 227 inside the first side face portion 214, and the eighth overlapping portion 228 inside the second side face portion 216 are overlapped with each other and sewn into more than one row (step S250).

[0147] In the method for manufacturing the ankle sock 200 according to the modified example of the second embodiment of the present invention, a plurality of blanks 200 are cut by the process of step S210, and the following processes can be selectively performed before performing the process of step S220.

[0148] Elastic bands 240 are temporarily joined at the upper edge of the front portion 212 of the blank 2, the edge of the first side face portion 214, and the edge of the second side face portion 216, respectively (performing the primary operation), or a reinforcing cloth 230 having a specified vertical height is temporarily joined along the boundary line BL formed by connecting between the bottom face portion 210 and the front portion 212, and a hot pressing operation (an operation of applying heat while applying pressure) can be performed on the temporarily joined portion of the elastic band 240 and / or the temporarily joined portion of the reinforcing cloth 230 (step S270). In this case, the reinforcing cloth 230 can be arranged such that the elongation rate in the longitudinal direction (cloth edge direction) is larger than the elongation rate in the transverse direction (thread opening direction). In addition, a friction member 250 made of a silicone material can be attached in a "T" shape to the portion corresponding to the heel in the ankle sock (step S280). In this case, instead of attaching the friction member 250 made of a silicone material, the silicone can also be coated or applied to the portion corresponding to the heel in the ankle sock.

[0149] The sock produced by the manufacturing method of the ankle sock 200 according to the second embodiment of the present invention as described above has the sewing thread, reinforcing cloth, elastic band, silicone friction member, etc. located on the inner side of the ankle sock by turning the sock inside out, and then the sock is worn.

[0150] The present invention is not limited to the above embodiments. Those of ordinary skill in the art should understand that various substitutions, deformations, and changes can be made without departing from the technical idea of the present invention.
