FOOT STABILIZING DEVICE

Description

BACKGROUND OF THE INVENTION

1. Technical Field

[0001] The present invention relates to a foot stabilizing device, and more particularly, to the foot stabilizing device that uses a reducing stress structure to reduce the force in contact with a user's foot.

2. Description of Related Art

[0002] A human foot contains 26 bones and 33 joints, and these bones and joints are covered by more than 100 muscles, tendons, ligaments, blood vessels, nerves, skin, and soft tissues. Regardless of standing or walking, the whole operation of the feet is very complicated.

[0003] Since both feet are provided for supporting the whole body weight and the structure of human bones and muscles intertwined with each other, therefore the knees and pelvis may be affected when there is a problem of the foot structure. In a more serious case, spine may be skewed, and the bone structure further affects the functions of human organs. Podiatric medicine begins to be taken increasingly more serious, and feasible solutions are provided by podiatric medicine to prevent the aforementioned problems.

[0004] In international podiatric medicine, insole is generally used as a foot aid to correct and treat foot problems. However, the design of most of the present existing insoles are based on the three-point mechanics of human arch, so that a transverse arch, an inner arch and an outer arch of the foot arch achieve a three-point stress balance. The present existing insoles come with various different designs, such as three support points according to the three-point mechanics which refer to protrusions or recesses formed at a first metatarsal position, a fifth metatarsal position, and a heel position, or a heel cup design attempting to cover and stabilize a user's foot. However, the contact position of the foot with the insole may be shifted after a long time of walking, so that the foot will slide on the insole, and an unstable situation of the feet may occur.

[0005] In addition, portions of a foot which are between a second phalange and a second metatarsus and between a third phalange and a third metatarsus protrude further to the outside than other metatarsus, and such corresponding portions still have a planar surface on the insole, and thus the foot may slide forward or sideway when these portions are in contact with the insole every time, and the foot stability for a perfect walking posture is ruined.

[0006] Patent application publication US 2010/0170107 A1 discloses a foot stabilizing device having the features of the preamble of claims 1, 2, 6 and 8. From patent application publication EP 2165617 A1 a shoe insert is known that is made of a resin material having thermoplastic properties and that comprises a raised ridge face located at the center region of the shoe insert. Likewise, patent application publication DE 3506809 A1 discloses a shoe insert having a raised cushion in the front part of the shoe insert. The insole known from patent application publication US 2005/0193591 A1 is made of silicone and comprises a section being made of a silicone-cork mixture, which section can be located on the outer edge of the insole, in its metatarsal region or in its heel region and is raised with respect to the remainder of the surface of the insole or is ground to the same height as said surface. Patent application publication US 2015/0143714 A1 discloses a foot balancing device in the form of an insole having one or more protuberances located in the middle region of the insole, namely at the center of gravity of a user's body. Patent specification US 1727244 A describes an auxiliary inner sole having a protuberance or raised portion in its front part.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

[0013] With reference to FIGS. 1 and 2 for a foot stabilizing device in accordance with embodiments of the present invention, the foot stabilizing device may be an insole body 10 or a sole body 11.

[0014] In FIG. 1, the foot stabilizing device, which is the insole body 10, has a toe region 21, a foot sole region 22, a foot arch region 23 and a foot heel region 24 sequentially disposed from an insole front-end 12a to an insole rear-end 13a of the insole body 10. In FIG. 2, the sole body 11 has a foot contacting surface 111, and a shoe body may be installed along an edge of the contour of the sole body 11 to build the structure of the shoe body. The foot stabilizing device, which is the sole body 11, has a toe region 21, a foot sole region 22, a foot arch region 23 and a foot heel region 24 disposed sequentially from a sole front-end 12b to a sole rear-end 13b of the foot contacting surface 111.

[0015] In FIG. 3, a foot may be divided into three main parts, respectively, forefoot, midfoot, and hindfoot. The toe region 21 and the foot sole region 22 are configured to be corresponsive to a user's forefoot, and the forefoot is formed by five toe phalanges and five metatarsus connected to the toe phalanges, wherein the phalange is formed by many small bones, and the metatarsus and the phalanges are connected to form a forefoot sole. The hindfoot has seven heel bones, and these heel bones are connected by ligaments and connected with five parallel metatarsal bones and primarily provided for supporting a user's body weight and maintain the balance of the user's body. The midfoot has a foot arch with an arch-shaped structure, and the foot arch comprises a transverse arch, an inner arch, and an outer arch, and these arches provide the functions of absorbing reaction forces coming from the ground, dispersing weight, and maintain the user's feet in a normal walking situation.

[0016] When the user's foot steps on the insole body 10 or the sole body 11, the user's toe is situated in the toe region 21, and the user's metatarsus is situated in the foot sole region 22, and the arch is situated in the foot arch region 23, and the heel is situated in the foot heel region 24.

[0017] In FIGS. 1 to 3, these preferred embodiments are characterized in that a reducing stress structure 30 is formed on the insole body 10 or the foot contacting surface 111 of the sole body 11 and disposed on the foot sole region 22. The reducing stress structure 30 is longitudinally extended from the center position of a rear end of the toe region 21 to the middle position of the foot sole region 22. The center position of the rear end of the toe region 21 refers to the position between a second toe and a third toe of the user's foot when the foot steps on the insole body 10 or the sole body 11. The middle position of the foot sole region 22 refers to the position between a second metatarsus and a third metatarsus of the user's foot when the foot steps on the insole body 10 or the sole body 11.

[0018] The reducing stress structure 30 has a width equal to one-third of the width of the insole body 10 or the foot contacting surface 111. In other words, the insole body 10 or the foot contacting surface 111 is divided into three equal parts along the horizontal direction, and the reducing stress structure 30 is situated at the middle position of the insole body 10 or the foot contacting surface 111 in the horizontal direction. The reducing stress structure 30 may be in an oval shape (or a triangular shape with three round angles), and the oval shape has a tapered end 32a proximate to the toe region 21 to fit the tapered shape of a human foot sole tapered from the metatarsus towards the phalange. By extending the reducing stress structure 30 longitudinally from the center position of the rear end of the toe region 21to the middle position of the foot sole region 22, the contact area and contact force between the second metatarsus and the insole body 10 or the sole body 11 as well as that between the third metatarsus and the insole body 10 or the sole body 11 can be reduced when the user lifts or drops the foot in a walk, so as to solve the problem of sliding the foot forward or sideway.

[0019] In FIGS. 4 to 6, the reducing stress structure 30a is further extended towards to the foot heel region 24 and to the front end of the foot arch region 23, so that the shape of the reducing stress structure 30a is changed from the oval shape into a better prolate elliptical shape for increasing the area of the reducing stress structure 30a. Similarly, both ends of the prolate elliptical shape have a tapered end 32b, and the reducing stress structure 30a has a width equal to one-third of the width of the insole body 10 or the foot contacting surface 111. With the installation of the reducing stress structure 30a, the user's walking posture is more stable, and the contact force between the position of the second metatarsus and the third metatarsus of the user's foot towards the toe ditch position and the heel position and the reducing stress structure 30a can be reduced to overcome the problem of sliding the foot forward while walking.

[0020] Regardless of the oval shape (or considered as a triangular shape with three round angles) or the prolate elliptical shape, both shapes are slender in coordination with the long shape of the foot bones. Compared with the traditional circular aid structure, the present invention can achieve a more effective effect of stabilizing the foot.

[0021] To cope with different sizes of the insole body 10 or the sole body 11, the reducing stress structure 30a in the prolate elliptical shape may have a length from 8.5 cm to 12 cm or from 8.8 cm to 11.7 cm, and a width from 2.5 cm to 4 cm, or from 2.8 cm to 3.7 cm.

[0022] In FIGS. 7 to 9, an assistant reducing stress structure 31 is installed on the foot contacting surface 111 of the insole body 10 or the sole body 11 to further reduce the stress imposed on the user's outer arch. The assistant reducing stress structure 31 is disposed at a lateral side of the foot arch region 23 which is the position opposite to the outer arch. The assistant reducing stress structure 31 is in the shape of a meniscus and disposed along an edge of the insole body 10 or the foot contacting surface 111, so that the short arc edge of the meniscus is disposed along the edge of the insole body 10 or the foot contacting surface 111. Even not fully shown in the figures, the assistant reducing stress structure 31 may be used selectively and flexibly with the reducing stress structure 30, 30a in the oval shape or the prolate elliptical shape. Similarly, the assistant reducing stress structure 31 can reduce the contact force of the user's foot outer arch with the insole body 10 and the sole body 11 and stabilize the foot and prevent it from shaking sideway.

[0023] In each of the aforementioned figures, the reducing stress structure 30, 30a or the assistant reducing stress structure 31 may be a structure with a concave upper surface. In FIGS. 10 and 11, as the foot stabilizing device is the insole body 10, the reducing stress structure 30a is a structure with a concave lower surface or a structure with both concave upper and lower surfaces. Even not shown in the figures, the assistant reducing stress structure 31 may also be a structure with a concave lower surface or a structure with both concave upper and lower surfaces for reducing the structural strength of the insole body 10 at the reducing stress structure 30, 30a or the assistant reducing stress structure 31, such that when the user's foot steps on the insole body 10 or the sole body 11, the contact force around a second metatarsus and a third metatarsus of the foot can be reduced.

[0024] In FIGS. 12 and 13, the reducing stress structure 30a or the assistant reducing stress structure 31 are made of a soft substance 40 with a hardness smaller than the hardness of the insole body 10 or the sole body 11. For example, the sectional view shows that a portion of the insole body 10 at the reducing stress structure 30a or the assistant reducing stress structure 31 is removed, and the soft substance 40 is filled and fixed to the insole body 10. The reducing stress structure 30a is just provided for illustration only, and the reducing stress structure 30 may also be made of a soft substance to achieve the effect of reducing the structural strength and the contact force.

[0025] In FIGS. 14 and 15, when the reducing stress structure 30, 30a or the assistant reducing stress structure 31 made of a soft substance 40 is applied to the sole body 11, just the sole body 11 in a portion of the foot contacting surface 111 corresponsive to the reducing stress structure 30, 30a or the assistant reducing stress structure 31 is removed, and then the soft substance 40 is filled and fixed to the sole body 11.

[0026] In FIG. 16, if the reducing stress structure is in an oval shape, a first balancing bump 51 is arranged in a region of the reducing stress structure 30 to further improve the stability of lifting and stepping the foot on the reducing stress structure 30. The first balancing bump 51 is disposed on a line of symmetry 33 of the reducing stress structure 30, wherein the line of symmetry 33 refers to the center line of reducing stress structure 30, and the reducing stress structure 30 is substantially symmetrical with respect to the line of symmetry 33. Wherein, the first balancing bump 51 has a height lower than the height of the surface of the insole body 10 or the sole body 11 in order to reduce the contact area and contact force of the user's sole with the insole body 10 or the sole body 11 while using the first balancing bump 51 to achieve the effect of supporting and balancing the user's foot.

[0027] To further improve the supporting and balancing effects, a second balancing bump 52 is added on an outer side of a region of the reducing stress structure 30 and inside the foot sole region 22, and the second balancing bump 52 is disposed on an extension of the line of symmetry 33.

[0028] In FIG. 17, when the reducing stress structure 30a is in the prolate elliptical shape, the first balancing bump 51 and the second balancing bump 52 may be formed in the region of the reducing stress structure 30a, and disposed on the line of symmetry 33 of the reducing stress structure 30a, and the height of the first balancing bump 51 and the second balancing bump 52 is lower than the height of the surface of the insole body 10 or the sole body 11 to also achieve the effect of supporting and balancing the user's foot.

[0029] Each implementation mode of the preferred embodiments is capable of reducing the contact force of the user's foot with the insole body 10 or the sole body 11 and overcoming the problem of rubbing the second metatarsus and the third metatarsus of the foot with the insole body 10 and the sole body 11, thereby improving the stability of the foot.

[0030] The features of the present invention are disclosed above by the preferred embodiment to allow persons skilled in the art to gain insight into the contents of the present invention and implement the present invention accordingly. The preferred embodiment of the present invention should not be interpreted as restrictive of the scope of the present invention. Hence, all equivalent modifications or amendments made to the aforesaid embodiment should fall within the scope of the appended claims.
