Description

[Technical Field]

[0001] The present application relates to the technical field of knitting, and in particular to anti-slip socks. [Background technology]

[0002] The heels of conventional socks generally employ the "single-shaped heel", "Y-shaped heel" or "L-shaped heel" processes, and the corresponding knitting structures are formed by scooping and pushing along the "single-shaped", "Y-shaped" or "L-shaped" knitting methods.

[0003] Of these, the "straight heel" knitting structure is difficult to produce in the desired heel shape because the knitting length is significantly limited by equipment conditions. The "Y heel" knitting process basically limits the angle of the branching part to around 45°, so when it is desired to increase the heel size according to the foot size, the angle of the knitting structure is limited, causing the shape of the sock to become loose and slip off, and it is not possible to achieve an effective slip-off prevention effect. The "L heel" process requires improvement in the hold of the heel of the leg.

[0004] Patent Document 1 discloses a comfortable sock that prevents slipping down. The sock opening and body are manufactured in a trumpet shape that is wider at the top and narrower at the bottom to fit the shin. The opening and body are knitted with elastic yarn, and the bottom of the body is positioned exactly at the top of the wearer's ankle. The heel of the sock is knitted in a Y-shape. However, this structure is only applicable to long socks, not short socks. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Taiwan Registered Utility Model No. 294846 Summary of the Invention [Problem to be solved by the invention]

[0006] The present application aims to provide slip-off prevention socks with better holding properties. [Means for solving the problem]

[0007] In order to solve the above-mentioned technical problems, the present application provides a slip-off prevention sock comprising a sock body, a heel portion, and a toe portion, the toe portion and the heel portion are both connected to the sock body, a first knitting structure, a second knitting structure, and a third knitting structure extend over at least a portion of the sock body and the heel portion, one end of the first knitting structure and one end of the second knitting structure are connected to each other at an inflection point portion, the first knitting structure has a scooping knitting structure, and the second knitting structure has a scooping knitting structure. The third knitting structure has a push-in knitting structure and a push-in knitting structure, and one end of the third knitting structure extends from the intersection of the pick-up push-in knitting structure of the second knitting structure and the push-in knitting structure, forming a first included angle with the second knitting structure, the third knitting structure and the first knitting structure are located on both sides of the second knitting structure, respectively, the first knitting structure extends toward the toe portion, and the second knitting structure extends toward the heel portion.

[0008] The slip-off prevention socks of the present application have one end of a first knitting structure with a scoop knitting structure (a scoop knitting structure is a knitting structure in which the number of needles in each loop gradually decreases as the number of knitted loops formed by scooping up with needles increases) connected to one end of a second knitting structure including a scoop push knitting structure at an inflection point, so the configurations of the first and second knitting structures resemble an L-shape. By using an L-shaped knitting method in the heel area, the sock stretches more evenly and more when pulled, ensuring the sock's hold and slip-off prevention and anti-slip effects. By adopting this knitting structure, the position of the seam loop in the toe area moves behind the toes under the pulling action of the knitting structure, resulting in a more rational position, improving the comfort of the sock's hold on the sole of the foot. Furthermore, the scoop knitting structure on the first knitting structure (a scoop knitting structure is a knitting structure in which the number of needles in each loop gradually decreases as the number of knitted loops formed increases by scooping up with needles) can provide better tensile strength to the connection between the sock body and the heel portion of the sock, and by adopting a push-in knitting structure extending toward the heel portion, the number of needles on the loops formed in the sock bottom can be increased without affecting the overall shape or hold of the sock, thereby improving comfort when worn. It can also be applied to a variety of socks, including long socks, short socks, and ankle socks.

[0009] Furthermore, by adding a third knitting structure, which is a pressed knitting structure, it is possible to insert more loops in the heel area, forming an improved L heel, increasing the height of the heel opening knitting, forming a higher heel, and making the socks less likely to slip off after wearing, thereby achieving better holding power and anti-slip effects.The purpose of raising the heel can be achieved by lengthening the scooped pressed knitting structure of the second knitting structure, but doing so would make the entire heel too large, causing wrinkles on the sole of the foot and affecting comfort when wearing.

[0010] To further cooperate with the second knitting structure and the third knitting structure, an anti-slip tape is further provided in the heel area, and the anti-slip tape is provided between the third knitting structure and the second knitting structure. Because more loops of flat knitting or the like can be inserted between the third knitting structure and the second knitting structure, a net sling-like effect is achieved between the second knitting structure and the third knitting structure, providing more installation space for the anti-slip tape, and the cooperation of these two greatly enhances the anti-slip effect of the heel area.

[0011] The anti-slip tape may be provided adjacent to an intersection of the pick-up forced knit structure and the forced knit structure of the second knit structure.

[0012] The scooped push knit structure of the second knit structure may be closer to the heel than the push knit structure.

[0013] The number of knitted loops in the first knitting structure may be fewer than the number of knitted loops in the second knitting structure. When the sock is pulled to put on or take off, the second knitting structure, which extends from the sock body toward the heel, is subjected to greater stress and deformation during the pulling process, while the first knitting structure extends toward the toe and forms a smaller angle with the pulling direction of the entire sock, so it is subjected to less tensile stress. By knitting a greater number of loops in the second knitting structure than in the first knitting structure, the widths at which the two knitting structures can withstand deformation and force when the sock is subjected to stress can be better balanced, stabilizing the sock structure and making it less likely to slacken.

[0014] In consideration of a better balance between deformation of the knitting structure and a width capable of receiving a force, the number of knitting loops of the third knitting structure may be less than the number of knitting loops of the second knitting structure.

[0015] In consideration of a better balance between deformation of the knitting structure and a width capable of receiving a force, the number of knitted loops of the third knitting structure may be less than the number of knitted loops of the first knitting structure, or the number of knitted loops of the third knitting structure may be more than the number of knitted loops of the first knitting structure.

[0016] The angle between the first and second knitting structures in the extension direction is 70° to 150°, and the second knitting structure may include a scoop-up push-in knitting structure to reinforce the connection, and the first knitting structure may include a scoop-up knitting structure to reduce the number of needles on the loops formed in the sock. The different knitting structures have different connection characteristics in the sock body. When the extension directions of the first and second knitting structures are set at approximately 90°, i.e., when the two knitting structures are perpendicular to each other, the effects of the knitting structures are maximized without canceling each other out, resulting in the most significant improvement in the tensile properties of the sock sole. Because socks are flexible knitted fabrics and it is difficult to completely fix their shape, in actual products, a similar effect can be achieved by positioning the knitting structures at approximately 90°.

[0017] The pick-up tucked knit structure and the tucked knit structure of the second knitting structure may be arranged in a straight line, or an obtuse angle may be formed between the extension directions of the pick-up tucked knit structure and the tucked knit structure of the second knitting structure.

[0018] The included angle between the scoop-up tuck knitting structure of the second knitting structure and the third knitting structure in the extending direction may be 20° to 110°.

[0019] The sock body has a sock bottom, and a fourth knitting structure and a fifth knitting structure extend over at least a portion of the sock body and the toe portion, one end of the fourth knitting structure and one end of the fifth knitting structure are connected to each other at an inflection point, or a flat-knit loop knitting structure is further provided between the fourth knitting structure and the fifth knitting structure, the fourth knitting structure extends toward the toe portion, and the fifth knitting structure extends toward the sock bottom, and the fourth knitting structure may have a scoop-up tucked knitting structure, and the fifth knitting structure may have a tucked knitting structure.

[0020] The toe area has a relatively regular shape, and the directions of tension and force are both relatively uniform. The fourth knitting structure toward the sole of the sock still uses a pressed knitting method, increasing the number of needles in the loop portion formed on the sole of the foot, and the third knitting structure toward the toe uses a scooped pressed knitting structure to reinforce the connection between the knitting structures, with little effect on the dimensions and structure of the upper of the sock. The knitting structure of the sock bottom with an increased number of needles provides a tighter and more even hold, improving comfort when wearing the sock. Furthermore, a flat-knit loop knitting structure is further added between the fourth and fifth knitting structures, creating an intermediate buffer zone that eliminates the protrusions caused by the fourth and fifth knitting structures, making the toe area more flat.

[0021] The included angle between the fourth knitting structure and the fifth knitting structure in the extending direction may be 70° to 160°.

[0022] The number of knitted loops in the fourth knitting structure may be greater than the number of knitted loops in the fifth knitting structure. [Effects of the Invention]

[0023] In summary, by further providing a third knitting structure, which is a tucked knitting structure, to the improved L-shaped heel anti-slip sock of the present application, it is possible to insert a greater number of loops in the heel area, thereby achieving even better holding power and anti-slip effects.

[0025] Specific embodiments of the present application will be described in more detail below with reference to the drawings and examples. The following examples are intended to illustrate the present application and are not intended to limit the scope of the present application.

[0026] Example 1 In Figures 1 and 2, 0 indicates that no loops are formed, and 1 indicates that a loop is formed. A forced knitting structure is a knitting structure in which the number of needles in each loop gradually increases as the number of knitted loops formed increases, and a pick-up knitting structure is a knitting structure in which the number of needles in each loop gradually decreases as the number of knitted loops formed increases by scooping up with the needles. A pick-up forced knitting structure is a structure in which a pick-up knitting structure is formed first and then a forced knitting structure is formed. In Figures 8 and 9, because there are too many needles on the loops to depict them all, designs are used to show the changing pattern of the number of needles on the loops and their correspondence with the knitting structure on the sock.

[0027] As shown in FIG. 1, in one possible embodiment, the actual pushing process involves one stitch being picked up on one side and two stitches being pushed in on the other side as the number of loops increases. Therefore, overall, -1 + 2 = 1 stitch, i.e., one more stitch is pushed in. As shown in FIG. 2, one stitch is picked up on one side as the number of loops increases. However, the present application does not impose any limitations on the specific knitting method for pushing and lifting. In other embodiments, the pushed knitting structure and the lifted knitting structure can be realized using different knitting methods. In particular, the number of needles for pushing and lifting in each loop is not limited. It is sufficient that the pushed knitting structure is a knitting structure in which the number of needles in each loop gradually increases as the number of knitted loops increases, and the lifted knitting structure is a knitting structure in which the number of needles in each loop gradually decreases as the number of knitted loops increases by lifting with the needles.

[0028] 3 and 4, the slip-off prevention sock 1 provided by the present application includes a sock body 13, a heel portion 12, and a toe portion 11, and the toe portion and the heel portion are both connected to the sock body, and a first knitting structure 21, a second knitting structure 22, and a third knitting structure 23 extend to at least a portion of the sock body and the heel portion. In other words, the first knitting structure, the second knitting structure, and the third knitting structure may extend only to the heel portion, or the first knitting structure, the second knitting structure, and the third knitting structure may extend only to the sock body, or the first knitting structure, the second knitting structure, and the third knitting structure may extend to both the sock body and the heel portion.

[0029] One end of the first knitting structure and one end of the second knitting structure are connected to each other at an inflection point, the first knitting structure has a pick-up knitting structure, the second knitting structure has a pick-up tucked knitting structure 222 and a tucked knitting structure 221, the third knitting structure has a tucked knitting structure, one end of the third knitting structure extends from the intersection of the pick-up tucked knitting structure and the tucked knitting structure of the second knitting structure and forms a first included angle β with the second knitting structure, the third knitting structure and the first knitting structure are located on both sides of the second knitting structure, respectively, the first knitting structure extends toward the toe portion, and the second knitting structure extends toward the heel portion.

[0030] Please refer to the conceptual diagrams of knitting structures in Figures 4 and 8. In Figure 4, the pick-up push-in knit structure is shown with a thick black line, the push-in knit structure is shown with a dashed line, and the pick-up knit structure is shown with a thin solid line. In Figure 8, the dark gray areas represent "1" active needles, and the light gray areas represent "0" inactive needles. However, the number of needles is not absolute and can vary depending on the needs of the process; this is merely a conceptual diagram of one of the needle numbers. The horizontal dashed line in Figure 8 represents the boundary between the push-in knit structure 221 and the pick-up push-in knit structure 222, and the vertical dashed line represents the correspondence between the pick-up knit portion 2221 and the push-in knit portion 2222.

[0031] The height of the knitting structure shown in Figures 8 and 9 indicates the number of knitting loops.

[0032] During the actual knitting process, the first knitting structure, the second knitting structure, and the third knitting structure can be completed continuously without interruption, using the knitting order of the third knitting structure (push-in knitting structure) → the pick-up push-in knitting structure of the second knitting structure (push-in knitting portion and push-in knitting portion) → the push-in knitting structure of the second knitting structure → the first knitting structure (push-in knitting structure). The knitting order is shown by the dashed arrows in Figure 4. The pick-up push-in knitting structure of the second knitting structure needs to be knitted twice in a back and forth direction, thereby forming the pick-up push-in knitting structure. The third knitting structure is followed by the pick-up knitting 2221 of the pick-up push-in knitting structure 222 of the second knitting structure, followed by the push-in knitting 2222 of the pick-up push-in knitting structure of the second knitting structure, and then the push-in knitting structure 221 of the second knitting structure, and finally knitting is completed.

[0033] The slip-off prevention socks of the present application have one end of a first knitting structure with a scoop knitting structure (a knitting structure in which the number of needles in each loop gradually decreases as the number of knitted loops formed by scooping up with needles increases) and one end of a second knitting structure including a scoop push knitting structure connected to each other at an inflection point. Therefore, the configurations of the first and second knitting structures resemble an L-shape, and the L-shaped knitting method used in the heel area allows for more uniform and greater stretch when the sock is pulled, ensuring the sock's hold and slip-off prevention / anti-slip effects. By adopting this knitting structure, the position of the seam allowance loop in the toe area moves behind the toes under the pulling action of the knitting structure, resulting in a more rational position, improving the comfort of the sock's hold on the sole of the foot. Furthermore, the scoop knitting structure on the first knitting structure (a scoop knitting structure is a knitting structure in which the number of needles in each loop gradually decreases as the number of knitted loops formed increases by scooping up with needles) can provide better tensile strength for the connection between the sock body and the heel portion of the sock, and by adopting a push-in knitting structure in the direction extending toward the heel portion, the number of needles on the loops formed in the sock bottom can be increased without affecting the overall shape or hold of the sock, thereby improving comfort when worn.

[0034] Furthermore, by adding a third knitting structure, which is a pressed knitting structure, it is possible to insert more loops in the heel area, forming an improved L heel, increasing the height of the heel opening knitting, forming a higher heel, and making the socks less likely to slip off after wearing, thereby achieving better holding power and anti-slip effects.The purpose of raising the heel can also be achieved by lengthening the scooped pressed knitting structure of the second knitting structure, but doing so would make the entire heel too large, causing wrinkles on the sole of the foot and affecting comfort when wearing.

[0035] Example 2 See Figure 5. To further enhance cooperation between the second knitting structure and the third knitting structure, an anti-slip tape can be provided in the heel area, and the anti-slip tape is provided between the third knitting structure and the second knitting structure in the longitudinal direction of the sock. Since more loops, such as flat knitting, can be inserted between the third knitting structure and the second knitting structure, a net-like effect is created between the second knitting structure and the third knitting structure, providing more space for the anti-slip tape. The cooperation of these two structures greatly enhances the anti-slip effect in the heel area. The anti-slip tape can be made of commercially available anti-slip tapes such as PVC, PE, polyolefins, and SEBS.

[0036] To further improve the anti-slip effect, the space around the intersection of the scooped-push knit structure and the push-push knit structure of the second knit structure is made larger, and an anti-slip tape is placed close to the intersection.

[0037] In this embodiment, the scooping pushed-in knit structure of the second knit structure is closer to the heel portion than the pushed-in knit structure.

[0038] In this embodiment, the number of knitted loops in the first knitting structure is fewer than the number of knitted loops in the second knitting structure. When the sock is pulled to put on or take off, the second knitting structure, which extends from the sock body toward the heel, is subjected to greater stress and deformation during the pulling process, while the first knitting structure extends toward the toe and forms a smaller angle with the pulling direction of the entire sock, so it is subjected to less tensile stress. By knitting a greater number of loops in the second knitting structure than in the first knitting structure, the widths at which the two knitting structures can withstand deformation and force when the sock is subjected to stress are better balanced, making the sock structure more stable and less likely to slacken.

[0039] In this embodiment, the number of knitting loops in the third knitting structure is less than the number of knitting loops in the second knitting structure, taking into consideration a better balance between deformation of the knitting structure and the width that can bear force.

[0040] In this embodiment, the number of knitting loops in the third knitting structure is less than the number of knitting loops in the first knitting structure, taking into consideration a better balance between deformation of the knitting structure and the width that can bear force.

[0041] In this embodiment, the included angle α between the first knitting structure and the second knitting structure in the extension direction is 90°, but in other embodiments, it may be 70°, 80°, 100°, 110°, 120°, 130°, 140°, 150°, etc. The second knitting structure includes a scoop-up push-in knitting structure to reinforce the connection, and the first knitting structure includes a scoop-up knitting structure to reduce the number of needles on the loop formed in the sock. The different knitting structures have different connection characteristics in the sock body. When the extension directions of the first knitting structure and the second knitting structure are set at approximately 90°, i.e., when the two knitting structures are perpendicular to each other, the effects of the knitting structures are maximized without canceling each other out, resulting in the most significant improvement in the tensile properties of the sock sole. Because socks are flexible knitted fabrics and it is difficult to completely fix their shape, a similar effect can be achieved in actual products by positioning the knitting structures at approximately 90°.

[0042] In this embodiment, the pick-up tuck knitting structure and the tuck knitting structure of the second knitting structure are arranged in a straight line, or an obtuse angle γ is formed between the extension directions of the pick-up tuck knitting structure and the tuck knitting structure of the second knitting structure.

[0043] In this embodiment, the included angle in the extension direction between the scoop-up tuck knitting structure of the second knitting structure and the third knitting structure is 80°, but in other embodiments it may be 20°, 30°, 40°, 50°, 60°, 70°, 89°, 100°, 110°, etc.

[0044] Example 3 In another embodiment, as shown in Figures 6 and 7, in addition to having the first knitting structure, second knitting structure, and third knitting structure shown in Figure 3, the sock body has a sock bottom, and a fourth knitting structure 41 and a fifth knitting structure 42 extend over at least a portion of the sock body and toe portion. That is, the fourth knitting structure and the fifth knitting structure may extend only over the toe portion, or the fourth knitting structure and the fifth knitting structure may extend over both the sock body and toe portion. A flat knit loop knitting structure is further provided between the fourth knitting structure and the fifth knitting structure, the fourth knitting structure extends toward the toe portion, and the fifth knitting structure extends toward the sock bottom, the fourth knitting structure has a scooped plucked knitting structure, and the fifth knitting structure has a plucked knitting structure. However, in other embodiments, one end of the fourth braided structure and one end of the fifth braided structure are connected to each other at an inflection point.

[0045] The toe area has a relatively regular shape, and the directions of tension and force are both relatively uniform. The fourth knitting structure toward the sole of the sock still uses a pressed knitting method, increasing the number of needles in the loop portion formed on the sole of the foot, and the third knitting structure toward the toe area uses a scoop pressed knitting structure to reinforce the connection between the knitting structures, with little effect on the dimensions and structure of the upper of the sock. The knitting structure of the sock bottom with an increased number of needles provides a tighter and more even hold, improving comfort when wearing the sock. Furthermore, a flat knit loop knitting structure is further added between the fourth and fifth knitting structures, creating an intermediate buffer zone that eliminates the protrusions caused by the fourth and fifth knitting structures, making the toe area even flatter.

[0046] Please refer to the conceptual diagrams of knitting structures in Figures 7 and 9. In Figure 7, the pick-up push-in knitting structure is shown in thick black lines, and the push-in knitting structure is shown in thick dashed lines. In Figure 9, the dark gray areas represent "1" active needles, and the light gray areas represent "0" inactive needles, but the number of needles is not absolute and can be changed according to the needs of the process, and this is just a conceptual diagram of one of the needle numbers.

[0047] In the actual knitting process, the fourth and fifth knitting structures can be completed continuously without interruption, using the knitting order of the fifth knitting structure (pushed knit structure) → weft knit loop → pick-up knit portion 411 of the pick-up pushed knit structure of the fourth knitting structure → pushed knit portion 412 of the pick-up pushed knit structure of the fourth knitting structure. The knitting order is indicated by the dashed arrows in Figure 7. The pick-up pushed knit structure of the fourth knitting structure requires two round trips to form the pick-up pushed knit structure. The fifth knitting structure is followed by a weft knit loop, immediately followed by the pick-up knit portion of the pick-up pushed knit structure of the fourth knitting structure, and then proceeds to the pushed knit portion of the pick-up pushed knit structure of the fourth knitting structure, and then finishes knitting.

[0048] In this embodiment, the extension lines are shown by thin dashed lines as in Fig. 7, and the included angle η in the extension direction between the fourth knitting structure and the fifth knitting structure is 120°. In other embodiments, it may be 70°, 80°, 90°, 100°, 110°, 130°, 140°, 150°, 160°, etc.

[0049] In this embodiment, the number of knitted loops in the fourth knitting structure is greater than the number of knitted loops in the fifth knitting structure.

[0050] In this application, anti-slip socks as shown in Figures 3, 5 and 6 are used as conceptual diagrams, but this application does not limit the specific shape or type of socks and includes all short socks, ankle socks, long socks, etc. The heel part, toe part and sock bottom part correspond to the heel, toes and sole of the wearer, respectively, and the remaining part is the sock body.
