Description

Technical Field

[0001] The present application relates to the technical field of insoles, and in particular to an insole for improving misaligned force lines. Background Art

[0002] As one of the most commonly used items, insoles play an irreplaceable role. Traditional insoles are usually a one-piece structure with a three-point support design, which is used to adjust the heel angle of flat feet to improve the force line and posture.

[0003] However, there are many reasons for the misalignment of the force line, which may occur simultaneously, such as the misalignment of the force line caused by calcaneal valgus and the misalignment of the force line caused by flat feet. Traditional insoles cannot effectively improve the misalignment of the force line caused by calcaneal valgus and flat feet.

[0004] Improvements are urgently needed to address the above issues. Utility Model Content

[0005] The purpose of the present application is to provide an insole for improving misalignment of force lines, which has the advantage of improving misalignment of force lines caused by calcaneal valgus and flat feet.

[0006] This application provides an insole for improving misaligned force lines. The technical solution is as follows:

[0007] The insole comprises an insole body, wherein a first protrusion is provided at a middle portion of the insole body in an area corresponding to the calcaneus, and the first protrusion abuts against the inner side of the calcaneus.

At the same time, by adding the first protrusion, thickness support is provided for the arch part of the flat foot, especially the inner side of the calcaneus, so that the height of the inner side of the calcaneus is effectively increased, and the height of the outer side of the calcaneus is avoided from being too high, thereby improving the calcaneal valgus, that is, improving the misalignment of the force line caused by calcaneal valgus and flat foot.

[0009] Furthermore, in the present application, the side of the first protrusion close to the edge of the insole body is arranged parallel to the edge of the insole body.

[0010] The insole provided by the present application is designed to improve the misalignment of the force line. The first protrusion is arranged on a side close to the edge of the insole body and is parallel to the edge of the insole body, so as to fit the edge position of the heel. While effectively supporting the inner side of the heel, it also fits more closely with the edge contour of the heel. On the basis of serving as a foot support component, it brings greater comfort to the foot support, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet.

[0011] Furthermore, in the present application, the side of the first protrusion away from the edge of the insole body is in an arc shape.

[0013] Furthermore, in the present application, the height of the first protrusion gradually decreases from the center point along the circumferential direction.

[0014] The insole for improving the misalignment of the force line provided by the present application has a first protrusion whose height gradually decreases circumferentially from the center point, thereby making the height distribution of the first protrusion more uniform and achieving smooth and fluent height changes. While providing effective support for the inner side of the heel, it enhances the stability and comfort of the support, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet.

[0015] Furthermore, in the present application, the surface of the first protrusion along the circumferential direction is provided with at least one annular layer from high to low.

[0016] Furthermore, in the present application, the thickness of the annular layer is 0.5 mm.

[0017] Furthermore, in the present application, the distance between two adjacent annular layers is greater than 0.5 mm.

[0018] Furthermore, in the present application, a plurality of second protrusions in the shape of strips are provided in the middle portion of the insole body along the length direction.

[0019] Furthermore, in the present application, the thickness of the second protrusion is 0.5 mm, and the thickness of the second protrusion is 0.4 mm.

[0020] Furthermore, in the present application, a third protrusion is provided on the middle portion of the insole body on the opposite side of the first protrusion, and the third protrusion acts on the outer side of the calcaneus.

At the same time, by adding the first protrusion, thickness support is provided for the arch part of the flat foot, especially the inner side of the calcaneus, so that the height of the inner side of the calcaneus is effectively increased, and the height of the outer side of the calcaneus is avoided to be too high, thereby improving the calcaneal valgus, that is, improving the misalignment of the force line caused by calcaneal valgus and flat foot; the side of the first protrusion close to the edge of the insole body is arranged parallel to the edge of the insole body, and is used to fit the edge position of the heel, While providing effective support to the inner side of the heel, it also fits more closely with the edge contour of the heel, and on the basis of serving as a foot support component, it brings greater comfort to the foot support, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet; the first protrusion is arc-shaped on the side away from the edge of the insole body, which is used to fit the middle position of the heel, and while providing effective support to the inner side of the heel, it also fits more closely with the middle contour of the heel, and on the basis of serving as a foot support component, it brings greater comfort to the foot support, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet; the height of the first protrusion gradually decreases circumferentially from the center point, which is used to make the height distribution of the first protrusion more uniform and achieve smooth and fluent height changes, while providing effective support to the inner side of the heel, enhancing the stability and comfort of the support, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet.

At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0029] Please refer to Figures 1 to 2 As shown, the present application provides an insole for improving the misalignment of the force line, comprising an insole body 1, a first protrusion 2 being provided in the middle portion of the insole body 1 in an area corresponding to the calcaneus, and the first protrusion 2 abuts against the inner side of the calcaneus.

[0030] Specifically, traditional insoles are usually a one-piece structure with a three-point support design, which is used to adjust the calcaneal angle of flat feet to improve the force line and improve the body posture. However, there are many reasons for the misalignment of the force line, or they may occur simultaneously. For example, the misalignment of the force line caused by calcaneal valgus and the misalignment of the force line caused by flat feet occur simultaneously. Traditional insoles cannot effectively improve the misalignment of the force line caused by calcaneal valgus and flat feet. Figure 3 As shown at B in the figure, B represents a schematic state of calcaneal valgus. Therefore, in order to solve the above problems, the present application provides an insole for improving the misalignment of the force line, including an insole body 1, a first protrusion 2 is provided in the middle part of the insole body 1 in the area corresponding to the calcaneus, and the first protrusion 2 abuts against the inner side of the calcaneus, wherein the insole body 1 is used to provide basic support for the foot, and the first protrusion 2 provides a specific reinforced support effect for the foot with calcaneal valgus, that is, it provides a further reinforced support effect on the inner side of the calcaneus, and improves the calcaneal valgus by increasing the thickness on the inner side of the calcaneus of the heel. At the same time, by adding the first protrusion 2, thickness support is provided for the arch part of the flat foot, especially the inner side of the calcaneus, so that the height of the inner side of the calcaneus is effectively increased, and the height of the outer side of the calcaneus is avoided to be too high, thereby improving the calcaneal valgus, that is, improving the misalignment of the force line caused by calcaneal valgus and flat foot, as shown in FIG. Figure 3 As shown in A in the figure, A represents the schematic state after using this insole to correct calcaneal valgus.

[0031] In some preferred embodiments, the side of the first protrusion 2 close to the edge of the insole body 1 is arranged parallel to the edge of the insole body 1 .

[0032] Specifically, the first protrusion 2 is arranged parallel to the edge of the insole body 1 on one side close to the edge of the insole body 1, and is used to fit the edge position of the heel. While effectively supporting the inner side of the heel, it also fits more closely with the edge contour of the heel. On the basis of serving as a foot support component, it brings greater comfort to the foot support, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet.

[0033] In some preferred embodiments, the side of the first protrusion 2 away from the edge of the insole body 1 is in an arc shape.

[0034] Specifically, the first protrusion 2 is arc-shaped on the side away from the edge of the insole body 1, which is used to fit the middle position of the heel. While effectively supporting the inner side of the heel, it also fits more closely with the middle contour of the heel. On the basis of serving as a foot support component, it brings greater comfort to the foot support, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet.

[0035] In some preferred embodiments, the height of the first protrusion 2 gradually decreases from the center point along the circumferential direction.

[0036] Specifically, the height of the first protrusion 2 gradually decreases from the center point along the circumferential direction, which is used to make the height distribution of the first protrusion 2 more uniform, achieve smooth and fluent height changes, and provide effective support for the inner side of the heel while enhancing the stability and comfort of the support, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet.

[0037] In some preferred embodiments, at least one annular layer 3 is provided on the circumferential surface of the first protrusion 2 from high to low.

[0038] Specifically, as a support component for the foot, it is necessary to provide sufficient support stability for the foot to prevent slippage or dislocation. Therefore, in this embodiment, at least one annular layer 3 is provided along the circumferential surface of the first protrusion 2 from high to low. By providing the annular layer 3, it provides support and anti-slip functions at different height positions. While providing stable support for the inner side of the heel, it also prevents the heel and the first protrusion 2 from slipping or dislocation during foot movement, thereby improving the support stability and anti-slip performance of the first protrusion 2 for the inner side of the heel, and further stably improving the misalignment of the force line caused by calcaneal valgus and flat feet. In addition, the annular layer 3 acts as a reinforcing rib to ensure the support strength of the overall structure.

[0039] In some preferred embodiments, the thickness of the annular layer 3 is 0.5 mm.

[0040] Specifically, in order to provide stable support for the inner side of the heel and a good anti-slip effect, and to prevent discomfort to the heel during the support process, in this embodiment, the thickness of the annular layer 3 is 0.5 mm. By setting the thickness of the annular layer 3 to 0.5 mm, a reasonable and adaptable value is used to make the annular layer 3 provide a stronger sense of comfort for the support of the inner side of the heel, while providing a stable support and a good anti-slip effect, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet.

[0041] In some preferred embodiments, the distance between two adjacent annular layers 3 is greater than 0.5 mm.

[0042] Specifically, in order to prevent the anti-slip effect from being weakened due to interference between adjacent annular layers 3, in this embodiment, the distance between two adjacent annular layers 3 is greater than 0.5 mm. Through the setting of the above structure, sufficient distance is left between the two adjacent annular layers 3, that is, a gap area is formed between the two adjacent annular layers 3, so that the two adjacent annular layers 3 can be arranged in a staggered and separated structural layout, thereby achieving the anti-slip effect of the staggered arrangement. When combined with the first protrusion 2, it provides stable support to the inner side of the heel while preventing sliding between the inner side of the heel and the first protrusion 2, thereby stably improving the non-straight force line caused by calcaneal valgus and flat feet.

[0043] In some preferred embodiments, a plurality of second protrusions 4 in the shape of strips are provided in the middle portion of the insole body 1 along the length direction.

[0044] Specifically, in addition to the heel, the arch of the foot also needs to be effectively supported, thereby further improving the non-straight force line caused by flat feet. Therefore, in this embodiment, a plurality of second protrusions 4 in the shape of strips are provided in the middle part of the insole body 1 along the length direction. By providing a plurality of second protrusions 4 in the shape of strips, a stable supporting effect is provided for the arch of the foot, thereby improving the non-straight force line caused by flat feet.

[0045] In some preferred embodiments, the thickness of the second protrusion 4 is 0.5 mm, and the thickness of the second protrusion 4 is 0.4 mm.

[0046] Specifically, in order to make the second protrusion 4 provide stable and comfortable support to the arch of the foot, while ensuring the support stability, the comfort of the support provided by the second protrusion 4 to the arch of the foot is enhanced. In this embodiment, the thickness of the second protrusion 4 is 0.5 mm, and the thickness of the second protrusion 4 is 0.4 mm. Through the setting of the above structure, the second protrusion 4 supports the arch of the foot with reasonable thickness and thickness, preventing excessive support to the arch of the foot due to the second protrusion 4 being too large, and insufficient support to the arch of the foot due to the second protrusion 4 being too small. At the same time, it fits the physiological angle of the arch of the foot better, so that the second protrusion 4 provides comfortable and fitting support to the arch of the foot, thereby improving the uneven force line caused by flat feet.

[0047] In some preferred embodiments, a third protrusion 5 is provided on the opposite side of the first protrusion 2 in the middle portion of the insole body 1 , and the third protrusion 5 acts on the outer side of the calcaneus.

[0048] Specifically, in order to provide the foot with reasonable and uniform support and fully and effectively improve the misalignment of the force line caused by calcaneal valgus and flat feet, not only the inner side of the calcaneus of the foot needs to be effectively supported, but the area of the foot located on the outer side of the calcaneus also needs to be moderately and effectively supported. Therefore, in this embodiment, the middle part of the insole body 1 is provided with a third protrusion 5 on the opposite side of the first protrusion 2, and the third protrusion 5 abuts against the outer side of the calcaneus. Through the setting of the above structure, the third protrusion 5 effectively supports the outer side of the calcaneus, and combined with the effective support of the first protrusion 2 for the inner side of the calcaneus, they jointly provide sufficient support for the calcaneus, thereby improving the misalignment of the force line caused by calcaneal valgus and flat feet.

[0049] Through the above technical scheme, the insole for improving the misalignment of the force line provided by the present application includes an insole body 1, and a first protrusion 2 is provided in the middle part of the insole body 1 in the area corresponding to the calcaneus, and the first protrusion 2 abuts against the inner side of the calcaneus, wherein the insole body 1 is used to provide basic support for the foot, and the first protrusion 2 provides a specific reinforced support effect for the foot with calcaneal valgus, that is, it provides a further reinforced support effect on the inner side of the calcaneus, and improves the calcaneal valgus by increasing the thickness on the inner side of the calcaneus of the heel. At the same time, by adding the first protrusion 2, thickness support is provided for the arch part of the flat foot, especially the inner side of the calcaneus, so that the height of the inner side of the calcaneus is effectively increased, and the height of the outer side of the calcaneus is avoided from being too high, thereby improving the calcaneal valgus, that is, improving the misalignment of the force line caused by calcaneal valgus and flat foot; the first protrusion 2 is arranged on a side close to the edge of the insole body 1 parallel to the edge of the insole body 1, and is used to fit the edge of the heel. The first protrusion 2 is positioned in the middle of the heel, and while effectively supporting the inner side of the heel, it also fits more closely with the edge contour of the heel. On the basis of serving as a foot support component, it brings greater comfort to the foot support, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet. The first protrusion 2 is arc-shaped on the side away from the edge of the insole body 1, which is used to fit the middle position of the heel. While effectively supporting the inner side of the heel, it also fits more closely with the middle contour of the heel. On the basis of serving as a foot support component, it brings greater comfort to the foot support, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet. The height of the first protrusion 2 gradually decreases circumferentially from the center point, which is used to make the height distribution of the first protrusion 2 more uniform and achieve smooth and fluent height changes. While providing effective support for the inner side of the heel, it enhances the stability and comfort of the support, thereby stably improving the misalignment of the force line caused by calcaneal valgus and flat feet.
