Description

Technical Field

[0001] This utility model relates to the field of sock technology, and in particular to a sock with foot protection function. Background Technology

[0002] Socks are a type of clothing worn on the feet, usually made of materials such as fabric, cotton, silk, nylon, polyester, spandex, and fibers, used to protect the feet, absorb sweat, keep warm, or as decoration.

[0003] Due to the significant structural differences between the medial and lateral sides of the forefoot, different pressures are experienced on each side during exercise, resulting in varying frictional forces. This friction can easily lead to foot discomfort. Current methods to alleviate this friction typically involve adding an abrasion-resistant layer to the bottom of socks. For example, Chinese utility model patent CN205409703U discloses an abrasion-resistant sock that enhances durability by adding an abrasion-resistant layer at the forefoot. However, simply placing an abrasion-resistant layer in a specific location cannot differentiate between the medial and lateral sides of the forefoot, nor can it reduce friction by controlling the expansion and contraction of the transverse plantar arch on the medial side of the forefoot, thus limiting its effectiveness in reducing foot friction.

[0004] Therefore, there is an urgent need for a type of sock to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a sock with foot protection function to solve the problem of foot discomfort caused by concentrated friction due to different forces on the inner and outer sides of the forefoot.

[0006] To achieve the above objectives, this utility model discloses a sock with foot protection function, comprising: a sock body, an inner protective part, and an outer protective part. The outer protective part is disposed on the outer side of the forefoot of the sock body, and the inner protective part is disposed on the inner side of the forefoot of the sock body. Both the outer and inner protective parts are made of elastic fabric, and an elastic gap is provided between the outer and inner protective parts. The stretchability of the elastic gap is greater than that of the inner and outer protective parts.

[0007] Preferably, the inner protective part has a higher weave density than the outer protective part and the main body of the sock.

[0008] Preferably, the width of the elastic interval is a, and the value of a ranges from 3 to 10 mm.

[0009] Preferably, the cross-sectional shape of the elastic spacer is arc-shaped or square.

[0010] Preferably, the first elastic modulus of the sock body at the metatarsophalangeal joint is greater than the second elastic modulus of the sock body in the longitudinal direction, and the first elastic modulus is 3-6 times the second elastic modulus.

[0011] Preferably, the inner protective part and the outer protective part are integrally woven with the sock body, or the inner protective part and the outer protective part are sewn onto the sock body.

[0012] Preferably, the inner protective portion, the outer protective portion, and the elastic spacer portion are located at the metatarsophalangeal joint of the forefoot.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model provides support for the inner and outer sides of the forefoot by setting up an outer protective part and an inner protective part, thereby increasing the strength of the sock and enhancing the wrapping effect of the sock on the foot in the forefoot area. This reduces the range of foot extension and contraction during exercise, reduces energy consumption, improves athletic performance, and reduces friction on the sole of the foot, thereby reducing sports injuries.

[0015] 2. An elastic spacer is positioned between the inner and outer protective sections. The stretchability of the elastic spacer is greater than that of the inner and outer protective sections. During exercise, the stretching of the elastic spacer helps to relatively fix the inner and outer sides of the foot, reducing friction caused by stress and preventing blisters. Simultaneously, the elastic spacer material releases the constraint on the transverse metatarsal arch, thereby enhancing its natural function.

[0016] 3. By setting the inner protective layer to have a higher weave density than the main body of the sock, the denser and more compact fibers on the inner forefoot area, which bears more weight, improve support. The outer protective layer has a lower weave density than the inner protective layer, making the fibers on the outer forefoot area softer and enhancing flexibility. This naturally adjusts the stress distribution in the groove area during movement, reducing friction between the inner and outer sides of the foot without affecting the natural function of the transverse metatarsal arch.

[0017] 4. The sock's main body has a lateral elastic modulus 3-6 times greater than its longitudinal modulus, providing better fit and support during exercise, reducing foot stretch and contraction, improving exercise efficiency, reducing energy consumption, and lowering the risk of sports injuries. This feature also reduces friction on the sole of the foot, further enhancing comfort and safety during exercise. Simultaneously, the sock's main body has a large longitudinal stretch, allowing adjustment of the high-elasticity support area to suit different foot shapes, making the sock suitable for a wider range of foot types.

[0024] 100. Sock body; 110. Inner protective part; 120. Elastic spacer part; 130. Outer protective part. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1-5 As shown, this utility model provides a sock with foot protection function, including: a sock body 100, an inner protective part 110, and an outer protective part 130. The outer protective part 130 is located on the outer forefoot side of the sock body 100 corresponding to the metatarsophalangeal joint, and the inner protective part 110 is located on the inner forefoot side of the sock body 100 corresponding to the metatarsophalangeal joint. Both the outer protective part 130 and the inner protective part 110 are made of elastic fabric. The weave density of the inner protective part 110 and the outer protective part 130 is higher than that of the sock body 100. An elastic spacer 120 is provided between the outer protective part 130 and the inner protective part 110. The stretchability of the elastic spacer 120 is greater than that of the inner protective part 110 and the outer protective part 130.

[0027] The outer protective part 130 and the inner protective part 110 use fabric structures of different densities. Since the medial forefoot bears more force, the inner protective part 130 uses a denser fiber weave to increase support; while the lateral forefoot uses a softer fiber structure to enhance the flexibility of this area. In other words, the weave density of the outer protective part 130 is lower than that of the inner protective part 110, so that the force distribution of the elastic spacer 120 can be naturally adjusted during movement, which not only reduces the friction between the medial and lateral sides of the forefoot, but also does not excessively restrict the extension and contraction function of the transverse metatarsal arch.

[0028] The inner protective part 110, the outer protective part 130, the elastic spacer part 120 and the sock body 100 can be woven together as one piece. Alternatively, for ease of weaving, the inner protective part 110, the outer protective part 130 and the elastic spacer part 120 can be woven first and then sewn onto the sock body 100.

[0029] An elastic spacer 120 is provided in the groove between the inner and outer sides of the forefoot. The stretchability of the elastic spacer 120 is greater than that of the inner protective portion 110 and the outer protective portion 130. During exercise, the stretching of the elastic spacer 120 keeps the inner and outer protective portions 110 and 130 relatively fixed to the position of the sole of the foot, reducing friction on the inner and outer sides of the sole and preventing blisters. Simultaneously, the elastic spacer 120 releases the constraint on the transverse metatarsal arch, thereby strengthening its natural function. In the above embodiment, the width of the elastic spacer 120 is 'a', and the value of 'a' ranges from 3 to 10 mm. The cross-sectional shape of the elastic spacer 120 is arc-shaped or square.

[0030] By providing the elastic spacer 120, and with the inner protective portion 110 and the outer protective portion 130 having a lower stretchability than the elastic spacer 120, the sock's wrapping effect on the foot is enhanced in the forefoot area, thereby reducing the foot's stretching range during exercise, reducing energy consumption, improving athletic performance, and reducing friction on the sole of the foot, thus reducing sports injuries.

[0031] The socks are elastic socks. The first elastic modulus at the metatarsophalangeal joint of the sock body 100 is greater than the second elastic modulus in the longitudinal direction of the sock body, and the first elastic modulus is 3-6 times the second elastic modulus. Furthermore, the longitudinal stretchability of the sock body 100 is 3-6 times greater than its lateral stretchability. This provides better fit and support during exercise, reduces foot stretching, improves exercise efficiency, reduces energy consumption, and lowers the risk of sports injuries. This feature also reduces friction on the sole of the foot, further improving comfort and safety during exercise. Simultaneously, the greater longitudinal stretchability allows for adjustment of the coverage of the high-elasticity support components according to different foot shapes, making the socks suitable for a wider range of foot types.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
