Description

Anti-slip socks Technical Field

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

[0002] The heels of traditional socks generally adopt a "straight heel", "Y heel" or "L heel" process, that is, the corresponding knitting structure is formed along the "straight" or "Y" or "L" shape by a picking needle knitting method.

[0003] The knitting length of the "straight heel" is largely limited by the equipment, making it difficult to achieve the ideal heel shape. Due to the knitting process, the angle of the bifurcated portion of the "Y-heel" is generally limited to around 45 degrees. If the heel is to be enlarged to suit the foot shape, the limited knitting angle will cause the sock to loosen and fail to achieve effective anti-slip effect. Furthermore, the "L-heel" process needs to improve the heel's wrapping effect.

[0004] Taiwan Patent Publication No. TWM294846U discloses a pair of comfortable socks that prevent slipping. The cuff and body of the socks are designed to fit the calf, with a wide top and narrow bottom. The cuff and body are woven from elastic yarn, with the lower edge of the body positioned just above the wearer's ankle. Furthermore, the heel of the sock sole is knitted in a Y-shaped pattern. However, this structure is only suitable for long socks and not for short socks. Application Contents

[0005] The purpose of this application is to provide an anti-slip sock with better wrapping performance.

[0006] In order to solve the above technical problems, the anti-slip socks provided in the present application include a sock body, a sock heel and a sock toe, and the sock toe and the sock heel are connected to the sock body. At least one part of the sock body and the sock heel is extended with a first weaving structure, a second weaving structure and a third weaving structure. One end of the first weaving structure and one end of the second weaving structure are connected together at a turning point. The first weaving structure has a picking needle weaving structure, the second weaving structure has a picking needle weaving structure and a pressing needle weaving structure, and the third weaving structure has a pressing needle weaving structure. One end of the third weaving structure extends from the intersection of the picking needle weaving structure and the pressing needle weaving structure of the second weaving structure to form a first angle with the second weaving structure. The third weaving structure and the first weaving structure are respectively located on both sides of the second weaving structure. The first weaving structure extends toward the sock toe, and the second weaving structure extends toward the heel.

[0007] The anti-slip socks in this application utilize a pick-up needle knitting structure (a pick-up needle knitting structure in which the number of needles per loop decreases as the number of loops increases). One end of the first knitting structure and one end of the second knitting structure, which includes a pick-up needle knitting structure, are connected at an inflection point. Thus, the first and second knitting structures form an L-shaped structure. By providing an L-shaped knitting pattern at the heel of the sock, the sock can be stretched more evenly and more significantly when pulled, ensuring its wrapping properties and anti-slip and anti-slip properties. With this knitting structure, the toe loops of the sock's toe cap are moved behind the toes under the stretching action of the knitting structure, resulting in a more appropriate position and improved comfort for the sock's wrapping of the foot. Moreover, the pick-up needle knitting structure on the first knitting structure (the pick-up needle knitting structure is a knitting structure in which the number of needles on each loop gradually decreases as the number of loops is increased due to the needles being picked up) makes the connection between the sock body and the heel of the sock have better stretchability. The use of the press-down needle knitting structure in the direction extending toward the heel of the sock can increase the number of needles on the loops of the sock sole without affecting the shape and wrapping of the entire sock, thereby improving the wearing comfort. The sock is also suitable for various socks, such as long socks, short socks, boat socks, etc.

[0008] Furthermore, a third knitting structure, a snap-stitch knitting structure, is also provided to accommodate more loops at the sock heel, creating an improved L-shaped heel. This increases the height of the heel cuff, creating a higher heel and making it harder for the sock to fall off, thus achieving better wrapping and anti-slip properties. While lengthening the snap-stitch knitting structure of the second knitting structure could also achieve a higher heel, this would also make the heel too large, causing wrinkles on the sole of the foot and affecting wearing comfort.

[0009] To further coordinate with the second and third knit structures, an anti-slip rubber strip is installed at the heel of the sock, located between the third and second knit structures. Because the space between the third and second knit structures can accommodate more stitches, such as flat stitches, the space between the second and third knit structures creates a net-like effect, providing more space for the anti-slip rubber strip. This combination greatly enhances the anti-slip effect of the sock heel.

[0010] Optionally, the anti-slip rubber strip is provided near the intersection of the picking needle knitting structure and the pressing needle knitting structure of the second knitting structure.

[0011] Optionally, the press needle knitting structure of the second knitting structure is closer to the heel of the sock than the press needle knitting structure.

[0012] Optionally, the first braided structure has fewer loops than the second braided structure. When putting on and taking off socks, the socks are stretched. The second braided structure, extending from the sock body toward the heel, experiences greater stress and deformation during this stretching process. The first braided structure, however, experiences less tensile stress because it extends toward the toe and has a smaller angle with the overall stretching direction. By weaving more loops in the second braided structure than in the first, the deformation and bearing amplitude of the two braided structures are more balanced when the sock is subjected to stress, maintaining the stability of the sock structure and preventing it from sagging.

[0013] Optionally, taking into account the more balanced deformation and bearing amplitude of the braided structure, the number of braiding turns of the third braided structure is smaller than that of the second braided structure.

[0014] Optionally, considering that the deformation and bearing capacity of the braided structure are more balanced, the number of braiding turns of the third braided structure is smaller than that of the first braided structure. Alternatively, the number of braiding turns of the third braided structure is greater than that of the first braided structure.

[0015] Optionally, the angle between the extension directions of the first and second braid structures is 70°-150°, wherein the second braid structure includes a pick-up needle braid structure for strengthening the connection, and the first braid structure includes a pick-up needle braid structure for reducing the number of needles required to form the sock loop. Different braid structures have different connection properties on the sock body. When the extension directions of the first and second braid structures are set at approximately 90°, that is, when the two braid structures are perpendicular to each other, the interaction between the braid structures can be maximized without mutual cancellation, and the tensile properties of the sock sole are most significantly improved. Because socks are flexible fabrics and their shape is not easily fixed, in actual products, braid structure arrangements of approximately 90° can achieve similar effects.

[0016] Optionally, the picking needle knitting structure and the press needle knitting structure of the second knitting structure are arranged in a straight line, or there is an obtuse angle between the extending directions of the picking needle knitting structure and the press needle knitting structure of the second knitting structure.

[0017] Optionally, the angle between the extension direction of the pick-up needle knitting structure of the second knitting structure and the extension direction of the third knitting structure is 20°-110°.

[0018] Optionally, the sock body has a sole, and at least a portion of the sock body and the toe is extended with a fourth knitting structure and a fifth knitting structure, one end of the fourth knitting structure and one end of the fifth knitting structure are connected together at a turning point, or a flat loop knitting structure is provided between the fourth knitting structure and the fifth knitting structure, the fourth knitting structure extends toward the toe, and the fifth knitting structure extends toward the sole; the fourth knitting structure has a pressing needle knitting structure, and the fifth knitting structure has a pressing needle knitting structure.

[0019] Because the toe section has a relatively regular shape, stretching and stressing are relatively uniform. The fourth knit structure, which faces the sole, uses press-stitching to increase the number of stitches in the looped portion of the sole. The third knit structure, which faces the toe, then uses a press-stitching structure to strengthen the connection between the knit structures, with minimal impact on the size and structure of the sock's upper. The increased stitch count in the sole knit structure provides a tighter and more even fit, enhancing the wearing comfort of the sock. Furthermore, a flat loop knit structure is placed between the fourth and fifth knit structures, creating a buffer zone to mitigate the protrusions caused by the fourth and fifth knit structures, resulting in a smoother toe.

[0020] Optionally, the included angle between the extension directions of the fourth braided structure and the fifth braided structure is 70°-160°.

[0021] Optionally, the number of braiding turns of the fourth braiding structure is greater than the number of braiding turns of the fifth braiding structure.

[0022] In summary, the improved L-shaped anti-slip socks at the heel are further provided with a third knitting structure of a press-needle knitting structure, so that the heel can accommodate more loops, thereby making the heel have better wrapping and anti-slip effects.

[0032] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] As shown in Figures 1 and 2, 0 represents no loops, and 1 represents loops. A press-stitch knitting structure is one in which the number of stitches per loop gradually increases as the number of loops increases. A pick-stitch knitting structure is one in which the number of stitches per loop gradually decreases as the number of loops increases due to the needles being lifted. A pick-stitch knitting structure is one in which the needles are first lifted and then pressed. Figures 8 and 9, because the number of stitches in the loops is too large to be easily depicted, use patterns to illustrate the changing pattern of stitch counts and their corresponding relationship to the knitting structure of the socks.

[0034] As shown in FIG1 , as an optional embodiment, the actual steps of pressing the needles are, as the number of circles increases, one needle is picked up on one side and two needles are pressed down on the other side, so the overall performance is -1+2=+1 needle more, that is, one needle is pressed down. As shown in FIG2 , picking up the needles is, as the number of circles increases, one needle is picked up on one side. However, the present application does not impose any restrictions on the specific knitting methods of pressing and picking up the needles. In other embodiments, the pressing needle knitting structure and the picking needle knitting structure can also be realized by different knitting methods. In particular, there is no restriction on the number of needles of pressing and picking up needles in each circle. Ultimately, as long as the pressing needle knitting structure can be realized as a knitting structure in which the number of needles on each circle gradually increases as the number of circles is knitted, and the picking needle knitting structure can be realized as a knitting structure in which the number of needles on each circle gradually decreases as the number of circles is knitted due to the needles being picked up, it will be sufficient.

[0035] Please refer to Figures 3 to 4. The present application provides an anti-slip sock 1, including a sock body 13, a sock heel 12 and a sock toe 11. The sock toe and the sock heel are both connected to the sock body, and at least one portion of the sock body and the sock heel is extended with a first knitting structure 21, a second knitting structure 22 and a third knitting structure 23. That is, the first knitting structure, the second knitting structure and the third knitting structure can extend only on the sock heel, or the first knitting structure, the second knitting structure and the third knitting structure can extend only on the sock body, or the first knitting structure, the second knitting structure and the third knitting structure can extend simultaneously on the sock body and the sock heel.

[0036] One end of the first knitting structure and one end of the second knitting structure are connected together at a turning point, the first knitting structure has a picking needle knitting structure, the second knitting structure has a picking needle knitting structure 222 and a pressing needle knitting structure 221, the third knitting structure has a pressing needle knitting structure, one end of the third knitting structure extends from the intersection of the picking needle knitting structure and the pressing needle knitting structure of the second knitting structure to form a first angle β with the second knitting structure, the third knitting structure and the first knitting structure are respectively located on both sides of the second knitting structure, the first knitting structure extends toward the sock toe, and the second knitting structure extends toward the sock heel.

[0037] Please refer to Figures 4 and 8 for the knitting structure diagrams. In Figure 4, the pick-and-press knitting structure is represented by thick black lines, the press-knitting structure by dashed lines, and the pick-and-press knitting structure by thin solid lines. In Figure 8, the dark gray areas represent active needles (number "1"), while the light gray areas (number "0") represent inactive needles. However, the number of needles is not absolute and can vary depending on process requirements. This diagram only illustrates one number of needles. The horizontal dashed line in Figure 8 represents the boundary between the press-knitting structure 221 and the pick-and-press knitting structure 222. The vertical dashed line indicates the correspondence between the pick-and-press knitting section 2221 and the press-knitting section 2222.

[0038] The height of the braided structure shown in Figures 8 and 9 refers to the number of braided turns.

[0039] In the actual knitting process, the first knitting structure, the second knitting structure and the third knitting structure can be completed continuously and uninterruptedly, adopting the following knitting order: the third knitting structure (pressing needle knitting structure) → the picking needle knitting structure of the second knitting structure (picking needle knitting part and pressing needle knitting part) → the pressing needle knitting structure of the second knitting structure → the first knitting structure (picking needle knitting structure). For the order of knitting, please refer to the order indicated by the dotted arrows in Figure 4, wherein the picking needle knitting structure of the second knitting structure needs to be knitted back and forth twice, so that the picking needle knitting structure is formed, and the third knitting structure is followed by the picking needle knitting part 2221 of the picking needle knitting structure 222 of the second knitting structure, followed by the pressing needle knitting part 2222 of the picking needle knitting structure of the second knitting structure, and then the pressing needle knitting structure 221 of the second knitting structure, until the knitting is completed.

[0040] The anti-slip socks in this application have a pick-up needle knitting structure (a pick-up needle knitting structure is a knitting structure in which the number of needles in each loop decreases as the number of loops is knitted). One end of the first knitting structure and one end of the second knitting structure, which includes a pick-up needle knitting structure, are connected together at an inflection point. Therefore, the first and second knitting structures form an L-shaped structure. By providing an L-shaped knitting method at the heel of the sock, when the sock is pulled, it can be stretched more evenly and to a greater extent, ensuring the sock's wrapping properties and anti-slip and anti-slip effects. After adopting this knitting structure, the position of the sock's toe loop moves to the back of the toes under the stretching action of the knitting structure, making the position more reasonable and improving the sock's wrapping comfort for the sole of the foot. Moreover, the pick-up needle knitting structure on the first knitting structure (the pick-up needle knitting structure is a knitting structure in which the number of needles on each loop gradually decreases as the number of loops is increased due to the needles being picked up) makes the connection between the sock body and the heel of the sock have better stretchability. The use of the press-down needle knitting structure in the direction extending toward the heel of the sock can increase the number of needles on the loop of the sock sole without affecting the shape and wrapping of the entire sock, thereby improving the wearing comfort.

[0041] Furthermore, a third knitting structure, a press-stitch knitting structure, is also provided to accommodate more loops at the sock heel, forming an improved L-shaped heel. This increases the height of the heel cuff, creating a higher heel and making it more difficult for the sock to fall off, thereby achieving better wrapping and anti-slip effects. Although lengthening the press-stitch knitting structure of the second knitting structure can also achieve the purpose of a higher heel, this would also make the heel too large, causing wrinkles on the sole of the foot and affecting wearing comfort.

[0042] Referring to Figure 5 , to further enhance the coordination between the second and third braid structures, an anti-slip rubber strip 3 can be provided at the heel of the sock. This strip is positioned longitudinally between the third and second braid structures. Because the space between the third and second braid structures can accommodate more stitches, such as flat stitches, the space between the second and third braid structures creates a net-like effect, providing more space for the anti-slip strip. This combination significantly enhances the anti-slip effect of the sock's heel. The anti-slip strip can be made from commercially available materials, such as PVC, PE, polyolefins, or SEBS.

[0043] In order to further improve the anti-slip effect, the space near the intersection is larger, and the anti-slip rubber strip is arranged near the intersection of the picking needle knitting structure and the pressing needle knitting structure of the second knitting structure.

[0044] In this embodiment, the pick-up needle knitting structure of the second knitting structure is closer to the heel of the sock than the press-needle knitting structure.

[0045] In this embodiment, the first braid structure has fewer loops than the second braid structure. Putting on and taking off socks causes stretching. The second braid structure, extending from the sock body toward the heel, experiences greater stress and deformation during this stretching process. The first braid structure, however, experiences less tensile stress because it extends toward the toe and forms a smaller angle with the overall stretching direction. The second braid structure has more loops than the first, ensuring a more balanced deformation and bearing capacity between the two braid structures when the sock is subjected to stress, maintaining a stable structure and preventing sagging.

[0046] In this embodiment, considering that the deformation and bearing amplitude of the braided structure are more balanced, the number of braiding turns of the third braided structure is smaller than that of the second braided structure.

[0047] In this embodiment, considering that the deformation and bearing amplitude of the braided structure are more balanced, the number of braiding turns of the third braided structure is smaller than that of the first braided structure.

[0048] In this embodiment, the angle α between the extension directions of the first and second braid structures is 90°. In other embodiments, it can also be 70°, 80°, 100°, 110°, 120°, 130°, 140°, 150°, and so on. The second braid structure includes a pick-up needle braid structure for strengthening the connection, and the first braid structure includes a pick-up needle braid structure for reducing the number of stitches required to form the sock loop. Different braid structures have different connection properties on the sock body. When the first and second braid structures extend at approximately 90°, that is, when the two braid structures are perpendicular to each other, the interaction between the braid structures is maximized without mutual cancellation, and the tensile properties of the sock sole are most significantly improved. Because socks are flexible fabrics and their shape is not easily fixed, in actual products, braid structures arranged at approximately 90° can achieve similar effects.

[0049] In this embodiment, the pick-up and press-down needle knitting structures and the press-down needle knitting structures of the second knitting structure are arranged in a straight line, or an obtuse angle γ is formed between the extending directions of the pick-up and press-down needle knitting structures and the press-down needle knitting structures of the second knitting structure.

[0050] In this embodiment, the angle between the extension direction of the picking needle knitting structure of the second knitting structure and the third knitting structure is 80°. In other embodiments, it can also be 20°, 30°, 40°, 50°, 60°, 70°, 89°, 100°, 110°, etc.

[0051] In another embodiment, as shown in Figures 6 and 7, in addition to the first, second, and third knitting structures shown in Figure 3 above, the sock body has a sock sole, and at least a portion of the sock body and the sock toe is extended with a fourth knitting structure 41 and a fifth knitting structure 42. That is, the fourth knitting structure and the fifth knitting structure can extend only on the sock toe, or the fourth knitting structure and the fifth knitting structure can extend only on the sock body, or the fourth knitting structure and the fifth knitting structure can extend on both the sock body and the sock toe. A flat loop knitting structure is further provided between the fourth knitting structure and the fifth knitting structure, with the fourth knitting structure extending toward the sock toe and the fifth knitting structure extending toward the sock sole; a press needle knitting structure is provided on the fourth knitting structure, and a press needle knitting structure is provided on the fifth knitting structure. However, in other embodiments, one end of the fourth knitting structure and one end of the fifth knitting structure are connected together at an inflection point.

[0052] Because the toe section has a relatively regular shape, stretching and stressing are relatively uniform. The fourth knit structure, which faces the sole, uses press-stitching to increase the number of stitches in the looped portion of the sole. The third knit structure, which faces the toe, then uses a press-stitching structure to strengthen the connection between the knit structures, with minimal impact on the size and structure of the sock's upper. The increased stitch count in the sole knit structure provides a tighter and more even fit, enhancing the wearing comfort of the sock. Furthermore, a flat loop knit structure is placed between the fourth and fifth knit structures, creating a buffer zone to mitigate the protrusions caused by the fourth and fifth knit structures, resulting in a smoother toe.

[0053] Please refer to Figures 7 and 9 for the knitting structure diagrams. In Figure 4, the pick-up needle knitting structure is represented by thick black lines, while the pick-up needle structure is represented by thin lines. In Figure 9, the dark gray areas represent active needles (number "1"), while the light gray areas (number "0") represent inactive needles. However, the number of needles is not absolute and can vary depending on process requirements. This diagram only illustrates one possible number of needles.

[0054] In the actual knitting process, the fourth knitting structure and the fifth knitting structure can be completed continuously and uninterruptedly, adopting the following knitting order: the fifth knitting structure (pressing needle knitting structure) → flat loop → the picking needle knitting part 411 of the picking needle knitting structure of the fourth knitting structure → the picking needle knitting part 412 of the picking needle knitting structure of the fourth knitting structure. For the order of knitting, please refer to the order indicated by the dotted arrows in Figure 7, wherein the picking needle knitting structure of the fourth knitting structure needs to be knitted back and forth twice, so that the picking needle knitting structure is formed, and the fifth knitting structure is followed by a flat loop, followed by the picking needle knitting part of the picking needle knitting structure of the fourth knitting structure, and then the pressing needle knitting part of the picking needle knitting structure of the fourth knitting structure is carried out until the knitting is completed.

[0055] In this embodiment, as shown in FIG7 , the extension line is a thin dashed line, and the included angle η between the extension directions of the fourth braided structure and the fifth braided structure is 120°. In other embodiments, the included angle η may be 70°, 80°, 90°, 100°, 110°, 130°, 140°, 150°, 160°, and so on.

[0056] In this embodiment, the number of braiding turns of the fourth braiding structure is greater than the number of braiding turns of the fifth braiding structure.

[0057] Although this application uses the anti-slip socks shown in Figures 3, 5, and 6 as schematic diagrams, this application does not limit the specific shape and type of socks, including all socks, boat socks, long socks, etc. The heel, toe, and sole of the sock correspond to the wearer's heel, toes, and sole of the foot, respectively, and the remaining part is the sock body.
