Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of rehabilitation auxiliary appliance, concretely relates to a correcting shoe sole that can correct internal eight or external eight gait. BACKGROUND

[0002] Internal eight gait is also called toe-in gait in medicine, which refers to the bad gait that the left foot toe deviates to the right and the right foot toe deviates to the left when walking, and external eight gait is also called toe-out gait in medicine, which refers to the bad gait that the left foot toe deviates to the left and the right foot toe deviates to the right when walking. During walking, the foot is mainly divided into three stages of heel landing, foot flat and toe lifting. During the forward movement of normal gait, the landing force point of the foot sole and the ground is along the center position near the heel to the front sole and basically maintains the parallel state with the body advancing direction, while the landing force point of the foot and the ground gradually deviates to the inside or outside during the forward movement of internal eight or external eight gait, and no longer is in the middle position of the front sole, and during the toe lifting stage, the foot lifting off the ground is accompanied by an action of toe rotating inward or outward, thereby causing internal eight or external eight gait. Therefore, compared with normal gait, internal eight or external eight gait is mainly caused by the deviation of the landing force point and the inward or outward rotating force. The included angle formed by the inner and outer sides of the front sole and the middle line longitudinal axis during walking is called foot rotation angle, and according to the foot rotation angle, eight gait is generally divided into mild, moderate and severe, and the mild one is less than 5 degrees, the moderate one is 5-10 degrees, and the severe one is more than 10 degrees. The metatarsal roll edge is a reference line transversing the front sole and perpendicular to the middle line longitudinal axis of the foot, and the metatarsal roll edge is located at the midpoint position between the first metatarsal bone position and the fifth metatarsal bone position. In theory, during the toe lifting stage, when the shoe sole follows the foot rolling to the metatarsal roll edge position to perform the action of lifting off the ground, the shoe sole has the maximum curvature degree when following the foot curling, and the foot landing force is also the largest.

[0003] There are various correction methods for the gait of internal or external eight, such as traditional correction methods such as physical therapy, bandage wrapping or external brace, etc. The special tool is complex to make, it is difficult to quickly adjust the tool related parameters according to the correction effect of the user, the applicability is poor, there are problems such as inconvenience to wear, low comfort, limited correction effect, affecting daily activities, etc. With the development of material science and ergonomics, some orthopedic shoes products designed for internal or external eight gait gradually appear on the market. The reverse last shoe is a common orthopedic shoe for treating internal or external eight gait, its design is relatively rigid, and the special design of the orthopedic shoe makes it have a large difference in appearance from the shoes worn daily, affecting the overall appearance and wearing experience, and is not suitable for long-term wear. At present, there are shoes with one side high and one side low with a certain inclination of the sole, which can adjust the foot force point of the user with internal or external eight gait to the center, so as to achieve the effect of correction. Although this design can help users correct internal or external eight gait when walking, when the user remains stationary, the inclined sole causes the user's feet to be pressed differently on both sides, resulting in an uncomfortable feeling, and long-term wear also easily causes the health risk of hallux valgus deformity, which is not suitable for long-term use, the correction effect is easy to repeat, and the correction period is long. Especially when providing corresponding correction and rehabilitation treatment for children, it is easy to produce resistance, pain and other negative emotions, increasing the difficulty of correction and rehabilitation treatment. The technical solutions provided in patent documents CN213130195U and CN214908749U have made corresponding improvements.

[0004] The patent document CN213130195U provides a correction insole for internal eight gait, which includes: a surface cortex plate embedded in the shoe cavity of the human body; a correction plate formed by a shapeable material as an integral piece, the correction plate includes a forefoot plate part and a hindfoot plate part which are placed on the upper surface of the surface cortex plate, the forefoot plate part is provided with an inclined edge abutting against both sides of the circumferential side wall in the shoe cavity, and the inclined edge and the end part of the surface cortex plate close to the front end of the shoe cavity have a spacing area. The reaction force of the ground on the human foot during walking will drive the foot to turn outward through the inclined edge, achieving the effect of correcting internal eight gait. According to the description and drawings of the patent document, it can be judged that there is a height difference between the forefoot plate of the correction insole and the spacing area, and the reaction force of the ground on the human foot is generated due to the height difference between the correction insole and the sole at the inclined edge.

[0005] The patent document CN214908749U provides a correction structure for correcting foot splay of adolescents, which comprises a first insole (1) and a second insole (2), characterized in that: the surfaces of the first insole (1) and the second insole (2) are fixedly installed with hard gaskets (3), the side of the first insole (1) is fixedly installed with a first soft gasket (4), the outer side of the first soft gasket (4) is fixedly installed with a male magic tape (5), the side of the second insole (2) is fixedly installed with a second soft gasket (6), the outer side of the second soft gasket (6) is fixedly installed with a female magic tape (7), and the surfaces of the first insole (1) and the second insole (2) are provided with folding seams (8). When in use, the toes of the first insole and the second insole can be folded along the folding seams, thereby achieving the correction effect, and the hard gaskets can effectively prevent the first insole and the second insole from deforming. According to the description and the drawings of the patent document, it can be judged that the toes of the first insole and the second insole form a height difference at the folding seam after being folded along the folding seam, thereby achieving the correction effect, and the hard gaskets are added to prevent the first insole and the second insole from deforming.

[0006] Through analysis, it can be known that the technical solutions provided by the patent document CN213130195U and the patent document CN214908749U both limit the position of the height difference of the shoe sole to the forefoot position, and partially solve the problem that the height difference of the inner and outer sides of the shoe sole causes the pressure on the two sides of the foot to be different, but in the process of use, the inclined edge or the folding seam still exists the state that the forefoot and the hindfoot are not balanced, and the problems of the foot shifting forward and deforming easily occur, and there is discomfort after wearing for a long time; in addition, the patent document CN213130195U adopts an inclined line, and the patent document CN214908749U adopts a folding seam, and both of them are straight line structures, which mainly adjust the correction degree and direction through the angle of the inclined line, and it is difficult to accurately correct according to the movement track of the human foot, thereby affecting the correction effect.

Specific embodiment 1

[0034] This experiment presents a novel corrective shoe sole that can correct in-toeing or out-toeing gait, combined with... Figure 1 and Figure 2 As shown, it includes: a sole body (1) and a figure-eight gait plate (2). The figure-eight gait plate (2) is embedded in the sole body (1). The figure-eight gait plate (2) is a rigid plate. The front sides of the figure-eight gait plate (2) have an outward protrusion (201) and an inward concave part (202) respectively. The outward protrusion (201) is located at the forefoot of the sole body (1) and extends towards the toes. The inward concave part (202) is located at the forefoot of the sole body (1) and retracts towards the heel. Because the figure-eight gait plate (2) is embedded in the sole body (1), the different magnitudes of the reaction forces exerted on the foot by the rigid figure-eight gait plate (2) and the relatively soft sole body (1), combined with the inclined edge formed by the outward convex part (201) and the inward concave part (202) at the front end of the figure-eight gait plate, when the human body walks, as the sole rolls forward with the foot to the front end of the figure-eight gait plate (2), the outward convex part (201) at the sole, which is still in the area of ​​force between the sole and the ground, and the inward concave part (202), which has been removed from the area of ​​force between the sole and the ground, exert different reaction forces on the foot through the sole, thereby causing the foot to rotate towards the outward convex part (201), achieving the purpose of correction. Compared with the prior art, this solves the problem of displacement caused by the height difference at the front end of the sole affecting the balance of foot force, and the figure-eight gait plate (2) is stable in position and will not deform.

[0035] Combination Figure 2 As shown, in this embodiment, when the upper surface of the figure-eight gait board (2) is set to be horizontal or parallel to the upper surface of the shoe sole body (1), the correction effect can be better achieved.

[0036] Combination Figure 1 As shown, when the rear end of the figure-eight gait plate (2) coincides with the rear end of the sole body (1), this structure is conducive to the use of the triangle formed by the midpoint of the heel, the midpoint of the convex part (201) and the midpoint of the concave part (202) to make the sole better drive the foot to move along the set foot movement correction trajectory when it rolls forward with the foot, thus achieving a better correction effect.

[0037] Combination Figure 1 As shown, the convex part (201) and concave part (202) at the front end of the figure-eight gait board (2) are set on both sides of the metatarsophalangeal rolling edge (7), with the convex part located on the toe side of the metatarsophalangeal rolling edge (7) and the concave part (202) located on the heel side of the metatarsophalangeal rolling edge (7). This structure ensures that when the foot rolls to the position of the metatarsophalangeal rolling edge (7), the force of the foot pushing off the ground is the greatest. At this time, the reaction force applied to the foot by the sole body (1) also reaches the maximum, resulting in a good corrective effect.

[0038] Combination Figure 1As shown, the front end of the splay gait plate (2) is provided with a smooth curve formed by the outer convex part (201) and the inner concave part (202), which is more conducive to adjusting the correction strength and direction, so that the shoe sole body (1) can accurately correct the movement trajectory of the human foot.
