Description

Technical Field

[0001] This invention relates to the field of sock technology, and more particularly to an arch support sock. Background Technology

[0002] Currently, arch support products mainly include arch support shoes, insoles, and socks. The main principle behind these products is to add support at the arch of the foot to prevent the arch from sagging, or to add elastic wrapping to the arch area to compress the apex of the arch and provide cushioning against sagging.

[0003] However, current products have the following problems: they cannot effectively support the arch triangle structure of the foot. The usual method is to add supports to the arch to reduce arch collapse. This method cannot fundamentally stabilize the arch triangle structure. Instead, it puts additional pressure on the already unstable structure, causing the already stretched ligaments to stretch even more, exacerbating ligament pressure, and compressing blood vessels and nerves in the sole of the foot, leading to new problems such as decreased foot health and comfort.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] like Figures 1-6As shown, the present invention discloses an arch support sock, comprising: a sock body 100, an elastic connecting band, a first fixing part 110 and a second fixing part 120 provided on the sock body 100, the first fixing part 110 being disposed on the sock body 100 corresponding to the position of the human foot near the forefoot, the second fixing part 120 being disposed on the sock body 100 corresponding to the position of the human heel, the elastic connecting band being disposed at the bottom of the sock body 100 and connecting the first fixing part 110 and the second fixing part 120, the positions of the first fixing part 110 and the second fixing part 120 relative to the human foot remaining unchanged.

[0036] The sock body 100 is a five-toed sock. The first fixing part 110 includes a finger loop 111 and a connecting part 112. Each toe of the sock body 100 is fitted with a finger loop 111. The connecting part 112 is connected to the finger loop 111. The connecting part 112 is located on the sock body 100 near the forefoot and surrounds the sock body 100.

[0037] In this embodiment, the first fixing part 110 is set in the style of a five-finger sock, making it difficult for the first fixing part 110 to move relative to the human foot, thereby keeping the distance between the first fixing part 110 and the second fixing part 120 unchanged, so that the elastic connecting band can perform its function.

[0038] To prevent relative displacement between the second fixing part 120 and the human foot, the second fixing part 120 is wrapped around the outside of the human heel, and an ankle fixing strap 150 is provided on the side of the sock body 100 near the ankle. The ankle fixing strap 150 is located on the sock body 100 near the ankle and is arranged around the sock body 100. The end of the ankle fixing strap 150 is connected to the second fixing part 120.

[0039] In this embodiment, the resistance from the second fixing part 120 covering the heel alone may not be sufficient to counteract the tension generated by the elastic connecting band. Therefore, an ankle fixing band 150 is needed to assist in fixing the position of the second fixing part 120 and prevent it from moving towards the toes. In the above embodiment, to improve the comfort of wearing the sock body 100, both the first fixing part 110 and the second fixing part 120 are integrally formed with the sock body 100. The ankle fixing band 150 is composed of multiple second elastic cords, which are woven together with the sock body 100. Fine elastic material is used, woven in a linear fashion with the sock fabric, ensuring heat dissipation and moisture wicking while enhancing the wrapping force of this part of the sock body, thus evenly distributing the tension of the elastic band.

[0040] In this embodiment, the elastic connecting band mimics the ligaments of the human body. The function of the elastic connecting band is the same as that of the plantar ligaments, both serving to support the longitudinal arch of the foot. For example... Figure 6As shown, the triangular structure of the medial and lateral longitudinal arches of the human foot is mainly composed of the calcaneus, talus, navicular bone, cuboid bone, medial cuneiform bone, first metatarsal bone, fifth metatarsal bone, and ligaments arranged in sequence. The apex of the arch-shaped structure consists of the talus and cuboid bone, the two sides are the calcaneus and the first and fifth metatarsal bones, and the base is formed by ligaments. The plantar ligaments connect one end to the side of the calcaneus and the other end to the side of the metatarsal bones. The two ends of the plantar ligaments that maintain stability at the bottom of the triangular structure of the longitudinal arch are attached to the heel and the metatarsophalangeal joint of the toe, respectively. To make the function of the elastic connecting band more similar to that of human ligaments, the connecting part 112 extends to the metatarsophalangeal joint of the foot, so that one end of the elastic connecting band is connected to the connecting part 112.

[0041] The elastic connecting band can be separate from, fixedly connected to, or integrally woven with the sock body 100. In this embodiment, the elastic connecting band can be separately set from the sock body 100, or glued to the sock body 100, or printed on the sock body 100 using three-dimensional printing technology, or integrally woven with the sock body 100. In this embodiment, the separate setting of the elastic connecting band from the sock body 100 is more beneficial for the protection of the transverse arch of the foot.

[0042] The elastic connecting band is detachably connected to the first fixing part 110 and the second fixing part 120, and can be separated from or detachably connected to the sock body 100. In this embodiment, different elastic connecting bands can be used for people with different body types or different arch shapes, increasing the product's targeting and improving support for different arches.

[0043] The elastic connecting belt is composed of multiple first connecting belts 131, one end of which is connected to the first fixing part 110 and the other end is connected to the second fixing part 120.

[0044] In this embodiment, since the sock body 100 is a five-finger sock, five first connecting straps 131 are provided, and each first connecting strap 131 is connected to a finger loop 111. This arrangement can distribute the tension of the elastic connecting strap, making the tension distribution of the elastic connecting strap more reasonable and increasing the comfort when wearing it.

[0045] One end of the second connecting strap 132 is connected to the side of the first fixing part 110, and the other end is connected to the second fixing part 120 located at the bottom of the sock body 100. The second connecting strap 132 gradually turns into the bottom of the sock body 100 from the side of the first fixing part 110. The second connecting strap 132 separates from the sock body 100 between the corresponding human heel and the human metatarsophalangeal joint.

[0046] In this embodiment, the second connecting strap 132 further optimizes the tension structure, making the first connecting strap 131 and the second connecting strap 132 more closely resemble the effect of human ligaments, providing better support for the transverse arch of the foot and improving wearing comfort. In the above embodiment, both the first connecting strap 131 and the second connecting strap 132 are elastic bands and are flat, which can reduce the feeling of foreign objects on the sole of the foot and improve wearing comfort. Simultaneously, the elastic connecting straps are colored, with different colors indicating different tensile strengths. The elastic band strength can be adjusted by changing the width to suit different weight groups, and is distinguished by color.

[0047] In this embodiment, compared to bony structures, ligaments have relatively low strength. Under conditions of high-intensity exercise or standing, excessive pressure can repeatedly stretch the plantar ligaments, causing ligament laxity and subsequently leading to arch collapse. By utilizing the tensile force generated by the deformation of the first connecting band 131 and the second connecting band 132, the plantar ligaments are helped to maintain the relative position of the calcaneus and metatarsals, stabilize the triangular structure, and reduce pressure on the plantar ligaments.

[0048] Support for the transverse arch of the foot is achieved by providing an arch reinforcement 140 at the arch of the sock body 100. The arch reinforcement 140 is a strap that surrounds the sock body 100. The arch reinforcement 140 is composed of multiple first elastic cords, which are woven together with the sock body 100.

[0049] In this embodiment, the transverse arch of the human foot is mainly composed of the forefoot formed by five metatarsal bones, and the midfoot formed by the medial, middle, and lateral cuneiform bones and the cuboid bone. The apexes of the forefoot and midfoot transverse arches are the second metatarsal bone and the middle cuneiform bone, respectively. The ligaments maintaining the transverse arch mainly include the dorsal metatarsal ligaments, the dorsal tarsometatarsal ligaments, and the plantar metatarsal ligaments. By adding a first elastic cord to the forefoot (near the toes) and midfoot areas and weaving it together with the sock body 100, stronger support is provided to maintain the structural stability of the transverse arch.

[0050] In this embodiment, the arch support is made of fine elastic filaments woven together with the sock fabric in a linear fashion, which ensures heat dissipation and moisture dissipation of the sock while enhancing the wrapping force of this part of the sock.

[0051] The bottom of the sock body 100 is equipped with anti-slip raised dots.

[0052] In this embodiment, the anti-slip bumps can improve the anti-slip performance of the socks.

[0053] In the above embodiment, the starting and ending points of the longitudinal arch support elastic connecting band are located at the heel and the metatarsophalangeal joint at the toe, which is the same as the plantar ligament that maintains stability in the bottom layer of the longitudinal arch's triangular structure. The plantar ligaments attach to the bones of the triangular structure and can work in conjunction with the foot muscles to effectively maintain arch stability. When the muscles are fatigued or the ligaments are loose, the bottom edge is passively stretched beyond its limit, and the triangular structure loses stability, causing the arch to collapse. At this time, the elastic connecting band located on the sole of the foot generates tension through deformation, fixing the bony structures on both sides, reducing the pressure of the stretched plantar ligaments, and stabilizing the longitudinal arch triangular structure. Furthermore, the elastic connecting band at the heel disperses the tension through the first fixing part 110 of the five-toe sock body, ensuring comfort and fixing the direction of the tension to prevent misalignment, maintaining the support force in the correct direction. The transverse arch support elastic band provides effective protection by reinforcing the forefoot and midfoot with the annular arch reinforcement part 140.

[0054] In summary, the elastic connecting band in this special design provides tensile strength that adapts to changes in exercise intensity, offering support for the arch of the foot without compressing the sole. It simultaneously satisfies the need for pressure-free support and significantly inhibits arch drop, thus meeting the public's demand for comfortable and safe arch support.

[0055] Example 2

[0056] The difference between this embodiment and Embodiment 1 is that the first fixing part 110 covers the sock body 100 corresponding to the position from the toe to the metatarsophalangeal joint of the human foot.

[0057] In this embodiment, the first fixing part 110 covers the area from the toe to the metatarsophalangeal joint of the sock body 100. Even if the first fixing part 110 is pulled by the elastic connecting band, it will not shift relative to the human foot. Furthermore, the sock body 100 can be any type of sock, not limited to five-toed socks.

[0058] Example 3

[0059] The difference between this embodiment and Embodiment 1 is that: the first elastic cord is flat and fixedly connected to the inner or outer side of the sock body 100, or integrally formed with the sock body 100. The second elastic cord is flat and fixedly connected to the inner or outer side of the sock body 100, or integrally formed with the sock body 100. The drawstring is flat and disposed on the inner or outer side of the sock body 100, or integrally formed with the sock body 100.

[0060] In this embodiment, the first elastic cord, the second elastic cord, and the drawstring can achieve their respective functions by being located on the inner or outer side of the sock body 100 or by being integrally formed with the sock body 100.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
