Similarly, the terms "upward," "downward," "vertical," "horizontal," and the like are used herein for illustrative purposes only, unless explicitly indicated otherwise.
The invention relates to an arch support sock, which comprises a sock body 1.0 and a support 2.0 for supporting an arch, wherein the sock body 1.0 is detachably connected with the support 2.0, and the support 2.0 is fixed at the arch part of the sock body 1.0 at least in use. As shown in figure 1, when the foot arch supporting sock is in use, the supporting member 2.0 is limited below the arch area of the user's foot, the user's pressing on the supporting member 2.0 can limit the supporting member 2.0 in the gap formed between the user's arch and the inside of the shoe, but in order to prevent the supporting member 2.0 from displacing when the user moves, the fixing part for limiting the supporting member 2.0 is arranged at the arch part of the sock body 1.0.
In some embodiments, the fixing portion is a pocket, a socket, a fixing band, etc. disposed at the arch portion of the sock body 1.0, and is made of the same material as the sock, and an elastic space for limiting the support 2.0 is formed between the fixing portion and the arch portion of the sock body 1.0. When in use, a user can insert the supporting piece 2.0 into the fixing part for fixing after wearing the sock body 1.0.
In some embodiments, the fixing portion is an insert disposed on the surface of the arch portion of the sock body 1.0, and the insert can be inserted into the theme cut structure of the support 2.0 so that the support 2.0 is limited under the arch portion of the sock body 1.0. The specific plug-in components can be hook-shaped structures fixed on the surface of the arch part of the sock body 1.0, the hook-shaped structures can stretch into the hollow-out structures 2.2 of the main body of the support 2.0 and are hooked with the connecting columns 2.22, and the support 2.0 and the sock body 1.0 are connected and fixed.
Because the sock body 1.0 is low in production cost and short in service life, the support piece 2.0 is higher in production cost relative to the sock body 1.0, and the service life is long, the split type detachable connection design of the support piece 2.0 and the sock body 1.0 is more reasonable, one support piece 2.0 can be matched with various sock bodies 1.0 for use, such as stockings, socks, sports socks and the like, and a user can select according to the self requirement.
With respect to the overall shape of the support 2.0, as shown in figures 2 and 3, the support 2.0 comprises two contact surfaces, respectively the surface which is in contact with the sole of the user's foot when in use and the surface which is in contact with the sole of the shoe, wherein the surface which is in contact with the sole of the user has a curvature which is ergonomically matched to the curvature of the arch of the foot of the human foot. In some embodiments, the support member 2.0 may be a unitary, thin-ended, thick-centered, shuttle-shaped structure. In some embodiments, as shown in fig. 3, to better fit the human arch, the portion of support 2.0 that is curved is intended to fit the side of the human arch. Specifically, the supporting member 2.0 includes a sole portion 2.0B and a foot side portion 2.0A connected to each other, the foot side portion 2.0A is bent upward relative to the sole portion 2.0B, and an angle between the sole portion 2.0B and the foot side portion 2.0A conforms to ergonomics.
In addition, support piece 2.0 includes frame 2.1 and main part hollow out construction 2.2, main part hollow out construction 2.2 includes a plurality of interconnect's unit 2.21, unit 2.21 is the geometry of constituteing by a plurality of spliced pole 2.22 and summit, and the inner edge of frame 2.1 is connected with a plurality of spliced pole 2.22 and/or summit of some of them unit 2.21, support piece 2.0 is made by elastic material, and laminates with user's arch through deformation under the exogenic action. Because support piece can take place certain deformation under the exogenic action, so general people (do not have the demand of correcting) use this function socks, support piece can play the absorbing effect in user's motion.
Specifically, the main body hollow structure 2.2 includes a plurality of units 2.21 connected to each other, and each unit 2.21 is a geometric body defined by a plurality of connecting columns 2.22 and a plurality of vertexes. Adjacent cells 2.21 are interconnected by sharing some of the same connecting studs 2.22 and vertices. In some embodiments, the units 2.21 of the main body hollow structure 2.2 are geometric bodies with the same shape and volume, wherein the geometric bodies can be regular geometric bodies or irregular geometric bodies; in other embodiments, the units 2.21 of the main hollow structure 2.2 may be geometric bodies with different shapes and/or volumes, wherein the geometric bodies may be regular geometric bodies or irregular geometric bodies. When the volume of the unit 2.21 in the local area of the support 2.0 is smaller, the number of the units 2.21 in the area is more distributed, and the pressure resistance in the local area is better, so the volume of the unit 2.21 in different areas of the support 2.0 can be adjusted according to the stress analysis data of the arch of the foot of the human body measured by big data. For example, the cells 2.21 close to the surface of the sock body 1.0 may be less bulky than the cells 2.21 remote from the surface of the sock body 1.0, thereby achieving a snug fit to the user's arch while further improving the bearing capacity of the support 2.0. Also for example, the cells 2.21 at both ends of the support 2.0 (relative to the user's arch) may be smaller in size relative to the cells 2.21 at the center of the support 2.0 (relative to the user's arch), thereby achieving a close fit to the user's arch while also being more ergonomic, further improving the carrying capacity of the support 2.0. For example, if the support 2.0 is shown in fig. 3, the sole portion 2.0B of the support 2.0 needs to provide greater support relative to the lateral foot portion 2.0A, so the unit 2.21 of the sole portion 2.0B of the support 2.0 can be smaller in volume relative to the unit 2.21 of the lateral foot portion 2.0A of the support 2.0, so that the sole portion 2.0B of the support 2.0 can provide greater support force.
In addition, the main body hollow structure 2.2 unit 2.21 of the support 2.0 of the present invention may be a regular geometric body, such as a prism, a pyramid, a tetrahedron, a hexahedron, an octahedron, a hexadecahedron, an icosahedron, and other polyhedral geometric bodies; in other embodiments, the units 2.21 of the body hollow structure 2.2 may also be irregular geometric bodies.
In some embodiments, the shape of the support 2.0 may be customized according to the shape of the arch of the user's foot, information about the user's foot may be obtained through a three-dimensional scanner, the support 2.0 adapted to the arch of the foot may be constructed through computer software, and then the corresponding support 2.0 may be printed through a 3D printing apparatus.
In some embodiments, the performance of the support 2.0 can be tailored to meet different usage requirements by adjusting variables including, but not limited to, the length, cross-sectional shape, cross-sectional area, variation in cross-sectional area of the connecting column 2.22 of the unit 2.21 in the longitudinal direction of the connecting column 2.22; the distribution density of the unit 2.21 in the integral hollow structure, the volume of the geometric body of the unit 2.21 and the geometric body of the unit 2.21. In particular, the degree of softness of the support element 2.0 can be varied by adjusting the above-mentioned variables, which degree of softness not only relates to the degree of deformation that can occur in the support element 2.0, but also relates to the wearing comfort of the user. A general supporting piece 2.0, wherein a connecting column 2.22 is cylindrical, and the diameter of the cross section is 0.5-1.5 mm; the bracing piece 2.0 for correction has a cylindrical connecting column 2.22 with a cross section of 1-3 mm.
