Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of footwear and apparel accessories, specifically to a pneumatic corrective sock. [Background Technology]
[0002] Hallux valgus is a skeletal deformity in which the big toe, which forms the first metatarsophalangeal joint, deviates laterally (the thumb points towards the index finger). It is one of the most common conditions affecting the big toe and even the forefoot. A 15° angle of deviation towards the index finger is called physiological hallux valgus; a 15-20° angle is called mild hallux valgus; a 20-40° angle is called moderate hallux valgus; and a greater than 40° angle is called severe hallux valgus. Hallux valgus can be caused by various factors, such as genetics and frequently wearing high heels or pointed shoes, which cause excessive outward deviation of the big toe. However, people with flat feet are more prone to hallux valgus because Asians generally have lower arches, so hallux valgus caused by flat feet has a certain incidence rate in China.
[0003] In view of this, this case involves in-depth research into the aforementioned issues, which led to the formation of this case. [Utility Model Content]
[0004] This invention aims to solve the technical problem of hallux valgus in patients with flat feet by providing a pneumatic corrective sock that uses the thrust of an air bladder to achieve targeted correction of the big toe and arch, thereby controlling the incidence of hallux valgus in patients with flat feet.
[0005] This utility model is implemented as follows: A pneumatic corrective sock includes a main body and a five-toe section connected to the front end of the main body; the five-toe section includes a thumb sleeve and an index finger sleeve, with a toe correction mechanism provided between the thumb sleeve and the index finger sleeve; the toe correction mechanism includes a first connecting surface and a second connecting surface connected to each other, the first connecting surface being connected to the index finger sleeve, and a first air bladder provided between the first connecting surface and the second connecting surface, the elasticity of the first connecting surface being less than that of the second connecting surface; the main body has an arch correction mechanism at the arch, the arch correction mechanism including a third connecting surface and a fourth connecting surface connected to each other, the two ends of the third connecting surface being fixedly connected to the bottom surface of the main body, the fourth connecting surface being located between the third connecting surface and the bottom surface of the main body, and a second air bladder provided between the third connecting surface and the fourth connecting surface, the elasticity of the third connecting surface being less than that of the fourth connecting surface.
[0006] Furthermore, the first airbag is provided with a first inflation port; the second airbag is provided with a second inflation port.
[0007] Furthermore, the first and third connecting surfaces are made of cotton fabric; the second and fourth connecting surfaces are made of elastic band material.
[0008] Furthermore, the elastic band material is any one of rubber elastic band, spandex elastic band, and TPU elastic band.

Detailed Implementation Methods
[0021] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing these embodiments and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.
[0023] Please see Figures 1 to 4 As shown, this utility model provides a pneumatic corrective sock 100, including a main body 1 and a five-toe section 2 connected to the front end of the main body 1; the five-toe section 2 includes a thumb sleeve 21 and an index finger sleeve 22, with a toe correction mechanism 3 provided between the thumb sleeve 21 and the index finger sleeve 22; the toe correction mechanism 3 includes a first connecting surface 31 and a second connecting surface 32 connected to each other, the first connecting surface 31 being connected to the index finger sleeve 22, and a first air bladder 33 being provided between the first connecting surface 31 and the second connecting surface 32, the elasticity of the first connecting surface 31 being less than the elasticity of the second connecting surface 32. After inflation, the first air bladder 33 stretches the second connecting surface 32, and the first air bladder 33 and the second connecting surface 32 generate a pushing force to push the thumb inward (i.e., away from the index finger), correcting the thumb. The inflation amount of the first air bladder 33 is determined by the required correction range. The main body 1 has an arch correction mechanism 4 at the arch of the foot. The arch correction mechanism 4 includes a third connecting surface 41 and a fourth connecting surface 42 that are connected to each other. The two ends of the third connecting surface 41 are fixedly connected to the bottom surface of the main body 1. The fourth connecting surface 42 is located between the third connecting surface 41 and the bottom surface of the main body 1. A second air bladder 43 is provided between the third connecting surface 41 and the fourth connecting surface 42. The elasticity of the third connecting surface 41 is less than that of the fourth connecting surface 42. After inflation, the second air bladder 43 expands and stretches the fourth connecting surface 42. The fourth connecting surface 42 generates a thrust to support the arch of the foot upward. The inflation amount of the second air bladder 43 is determined by the required correction range.
[0024] This utility model of pneumatic corrective stockings uses the thrust of airbags to achieve targeted correction of the big toe and arch of the foot, improve hallux valgus and flat feet, and effectively control the incidence of hallux valgus in patients with flat feet.
[0025] The toe correction mechanism 3 and the arch correction mechanism 4 are designed such that the elasticity of the first connecting surface 31 is less than that of the second connecting surface 32, and the elasticity of the third connecting surface 41 is less than that of the fourth connecting surface 42. This causes the second connecting surface 32 and the fourth connecting surface 42 to bulge or expand after the airbag is inflated, providing thrust. The shape changes of the first connecting surface 31 and the third connecting surface 41 are limited after inflation. The first connecting surface 31 acts as a positioning surface, and the third connecting surface 41 acts as a supporting surface.
[0026] In this invention, the first airbag 33 has a first inflation port 34, and a first through hole (not shown) is formed on the first connecting surface 31 or the second connecting surface 32 to facilitate the insertion of the inflation device into the first inflation port 34 for inflation; the second airbag 43 has a second inflation port 44, and a second through hole (not shown) is formed on the third connecting surface 41 or the fourth connecting surface 42 to facilitate the insertion of the inflation device into the second inflation port 44 for inflation. Preferably, the first inflation port 34 is oriented upwards, i.e., the opening faces the instep, and the second inflation port 44 is oriented inwards to avoid the inflation port causing discomfort to the foot and increase comfort. Preferably, the inflation device is a common inflator for balls; the structure of the inflation port is the same as that of the inflation port for balls.
[0027] In this invention, the first connecting surface 31 and the third connecting surface 41 are made of, but are not limited to, cotton cloth. Cotton cloth has poor elasticity and its shape changes are limited after inflation. The second connecting surface 32 and the fourth connecting surface 42 are made of elastic band material. Elastic band material has good elasticity and its deformation is significant after inflation, producing bulges or expansion to provide thrust.
[0028] In this invention, in order to ensure the elasticity of the second connecting surface 32 and the fourth connecting surface 42, the elastic band material is any one of rubber elastic band, spandex elastic band, and TPU elastic band.
[0029] In this invention, the first connecting surface 31 is connected to the index finger sleeve 22 by Velcro or sewing.
[0030] In this utility model, the third connecting surface 41 includes a first fixing end 411 and a second fixing end 412; the first fixing end 411 and the second fixing end 412 are connected to the bottom surface of the main body 1 by Velcro or sewing.
[0031] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
