[0002] In a part of the population, the walking posture is abnormal due to diseases or long-term bad habits, such as the people with pigeon-toed or pigeon-toed walking and the people with cerebral palsy. Although there is deflection in the walking posture of these two groups of people, there are still some differences, such as the pigeon-toed or pigeon-toed walking mainly lands on the heel first, while the people with cerebral palsy mainly land on the forefoot first. For O-shaped legs (pivoted), the sole components disclosed in the prior art such as publication number CN 101155524 B provide an opposite torque to achieve the correction or walking aid of the walking posture of this group of people. In fact, this type of shoes is highly targeted, single in function, small in audience, high in manufacturing cost, and the sole components are prone to uneven wear due to protrusion on the sole surface and smaller in force area. Summary of the invention

[0003] In view of the shortcomings of the above walking aid shoes, which have single functions and a small audience, the purpose of the present invention is to provide a multifunctional walking aid shoe that can be selectively suitable for different groups of people and reduce uneven wear. By setting reserved grooves at the forefoot and heel positions of the sole, the first component that can generate torque can be selectively detachably installed in the reserved grooves of the forefoot or heel, so as to achieve the function of adapting to use by different groups of people, and the first elastic rib can be changed in position by a screw and a lower seat that can be adjusted relative to the upper seat.

[0004] To this end, the present invention provides a multifunctional walking-aiding sole, comprising a first component, a second component, and reserved grooves arranged on the lower surfaces of the forefoot and the heel of the sole, wherein the first component is detachably connected to one of the reserved grooves, and the second component is detachably connected to the other reserved groove, the first component comprises a base and a first elastic rib arranged on the base, the first elastic rib is inclined and arranged in a radial line, and the elastic rib is deformed when subjected to pressure and generates a torque opposite to the deflection trend of the foot, the first component protrudes from the lower surface of the sole, and the sole is provided with a screw, and the screw is arranged in the reserved groove, A threaded hole cooperating with a screw is provided at the center of the first component and the second component, and the first component and the second component are threadedly connected to the screw arranged on the forefoot and the heel respectively. The base of the first component includes an upper seat and a lower seat, and the upper seat is threadedly connected to the screw, and a hole is provided in the middle of the lower seat. The first elastic rib is fixed on the lower seat, and a limiting assembly is provided between the upper seat and the lower seat. The limiting assembly limits the rotation of the lower seat relative to the upper seat or limits the rotation of the lower seat relative to the upper seat in the torque direction of the first component, so that the lower seat can rotate to a predetermined direction to realize the conversion of the position of the first elastic rib.

[0005] Furthermore, the directions of the internal thread of the first component and the corresponding external thread of the screw are arranged so that the tightening direction of the first component is the same as the direction of the torque generated after the first component is compressed.

[0006] Furthermore, a plug hole is provided in the reserved groove, and corresponding plug holes are provided at a predetermined distance from the center of the first component and the second component for inserting the plug rod.

[0007] Furthermore, the ends of the insertion rod and the screw rod are provided with a cover body.

[0013] The present invention provides a multifunctional walking-assisting shoe sole, with reserved grooves arranged at the forefoot and heel of the sole. The first component is a corrective or walking-assisting component, and its inclined first elastic ribs can generate torque when subjected to force (when stepping on the bottom surface). The torque is opposite to the direction of deflection of the human foot. When the first component is arranged at the heel of the sole, it can be suitable for inward-toed or outward-toed walking. When the first component is arranged at the forefoot, it can be used by people with cerebral palsy.

[0014] In a specific embodiment of the present invention, the first component is fixed to the sole by a screw connection, and through the threaded arrangement of the screw and the first component, the direction of the torque generated after the first component is compressed is the same as the direction in which the first component is tightened, so that the first component can correctly generate a torque opposite to the deflection direction of the human foot.

DETAILED DESCRIPTION

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] Reference Figures 1 to 5 As shown, a multifunctional walking-aiding sole of the present invention comprises a first component 5, a second component 6, and reserved grooves 4 arranged on the lower surface of the forefoot part 2 and the heel part 3 of the sole 1. The first component 5 is detachably connected to one of the reserved grooves 4, and the second component 6 is detachably connected to the other reserved groove. The first component 5 comprises a base and first elastic ribs 501 arranged on the base. The first elastic ribs 501 are inclined and arranged radially. When the first elastic ribs 501 are subjected to pressure, they deform and generate a torque opposite to the deflection trend of the foot. The first component 5 protrudes from the lower surface of the sole 1. In this embodiment, referring to Figure 1 As shown, the reserved groove 4 of the forefoot part 2 is located on the inner side of the forefoot area, that is, corresponding to the metatarsal area of ​​the big toe of the forefoot, and the reserved groove 4 of the heel part 3 is generally set in the middle position of the heel part 3. The reserved grooves 4 of the forefoot part 2 and the heel part 3 have the same shape, and the first component 5 or the second component 6 can be installed in the reserved groove 4 of the forefoot or heel part. The first component 5 is used to generate torque and does not actually rotate. Therefore, the reserved groove 4, the first component 5 and the second component 6 do not necessarily need to adopt a circular structure. Other shapes can also generate torque. The present invention adopts a circular structure, which is mainly convenient for installation. The main function of the second component 6 is to fill the reserved groove 4, so the second component 6 can be flush with the sole 1 after installation, refer to Figure 2 As shown, the second component 6 used in this embodiment includes a base, on which a radial second elastic rib 601 is arranged, and the lower surface of the second elastic rib 601 is flush with the lower surface of the sole 1. The second elastic rib 601 does not generate torque, but can play an anti-slip role. The first component 5 is a core component that generates torque to achieve a correction or walking aid effect. The principle of this structure has been disclosed in the patent publication with publication number CN101155524B. This embodiment uses a similar structure, and there is no difference in the length of adjacent first elastic ribs. Of course, they can also be different. Refer to Figure 3 , Figure 4 and Figure 5 As shown, the first component 5 includes a base and a first elastic rib 501 arranged on the base in a radial shape, referring to Figure 4 As shown, the two ends of the first elastic rib 501 are connected by an arc-shaped sheet structure. It should be noted that the first elastic rib can be set inward or outward, which is suitable for inward or outward. Since the deflection directions of the foot are opposite, the rotation directions of the first elastic ribs of the corresponding first member should also be different. Figure 5 As shown, the angle between the first elastic rib 501 and the base is an acute angle, so when the shoe contacts the bottom surface, the first elastic rib 501 is subjected to downward pressure. Since the angle between the first elastic rib 501 and the ground is an acute angle, the pressure will cause the first elastic rib 501 to bend and deform, so the first elastic rib 501 will generate an opposite elastic force, which forms a torque relative to the center of the base. The torque is opposite to the direction of the human body's outward deflection (such as outward toe), thereby correcting the walking posture or assisting walking. Figure 1 , Figure 2As shown, the first component 5 and the second component 6 are fixed to the sole 1 in a detachable manner. In this embodiment, a screw 7 is specifically used for connection. The screw 7 can be made of plastic or metal. The screw 7 is preformed in the sole 1. The other end of the screw 7 can be connected to the hook. The top of the screw 7 can be connected to the bottom plate. The bottom plate and the hook are riveted. In other embodiments, the screw can also be set in the base. The base is formed into the sole. This connection structure mainly prevents the screw 7 from separating from the sole 1 after being stressed, or the screw 7 pierces the sole 1 upward to cause damage. The center of the base of the first component 5 and the second component 6 is provided with a threaded hole for fixing on the screw 7. The base can be made of plastic. The other end of the screw 7 does not protrude from the sole 1 to avoid the screw 7 from contacting the ground during walking.

[0028] In the above embodiment, the directions of the internal thread of the first member 5 and the external thread of the corresponding screw rod 7 are set so that the tightening direction of the first member 5 is the same as the direction of the torque generated after the first member 5 is compressed. The torque generated by the first member 5 during walking will cause the first member 5 to have a tendency to rotate. When the direction of the rotation tendency is the same as the tightening direction between the first member 5 and the screw rod 7, the first member 5 can be prevented from loosening, and the first member 5 can also be prevented from reducing the torque acting on the sole 1 by rotating.

[0029] In the above embodiment, referring to Figure 1 , Figure 2 As shown, the reserved groove 4 is provided with a plug hole 401, and the plug holes are arranged on both sides of the threaded hole in a mirror-symmetrical manner. The plug hole 401 is used to insert the plug rod. The first component 5 and the second component 6 are also provided with corresponding plug holes 401. The plug rod can be made of plastic. The plug rod can limit the rotation of the first component 5 relative to the sole 1. Fig. 9 As shown, the insertion hole 401 of the first member 5 can be set as a polygonal stepped hole and inserted into the connecting tube 402 with a hole in the middle. The outer wall of the upper part of the connecting tube 402 is also polygonal and matches the polygonal inner wall of the upper part of the stepped hole to prevent relative rotation. The lower outer wall of the connecting tube 402 passing through the base is provided with an external thread, and a thread groove is provided at one end of the cover body. The thread groove is provided with an internal thread. The cover body 8 is threadedly connected with the connecting tube 402 to restrict the insertion rod to the base of the first member 5. The end of the screw rod 7 is also provided with a cover body 8, and the structure is basically the same as that of the cover body 8 of the insertion rod.

[0030] In the above embodiments, there are still some problems in actual use, such as eccentric wear. For example, in the case of people walking with their feet turned outward, due to the posture of the group, the first component 5 protrudes from the surface of the sole 1, and its main contact surface is the first elastic rib 501, which has a smaller contact surface than the sole 1. Therefore, this eccentric wear phenomenon also exists on the first component 5, and this eccentric wear will affect the deformation capacity of the first rib elastic rib. Figure 6As shown, an improved solution, the base of the first component 5 includes an upper seat 502 and a lower seat 503, the upper seat 502 is threadedly connected to the screw rod 7, a hole is provided in the middle of the lower seat 503, the first elastic rib 501 is fixed on the lower seat 503, and a limit assembly is provided between the upper seat 502 and the lower seat 503, which limits the lower seat 503 to rotate relative to the upper seat 502 or to rotate relative to the upper seat 502 toward the torque direction of the first component 5. Figure 7 As shown, the lower surface of the upper seat 502 and the upper surface of the lower seat 503 are provided with a limiting strip 504 and a limiting groove 505 that cooperate with each other, the end of the screw 7 is threadedly connected to the cover body 8, and the cover body 8 is screwed until the upper end surface of the cover body contacts the lower surface of the lower seat 503. When the cover body 8 is pressed against the surface of the lower seat 503, the lower seat 503 and the upper seat 502 are in close contact, the limiting strip 504 and the limiting groove 505 cooperate with each other, the lower seat 503 and the upper seat 502 are fixed, the upper seat 502 and the screw 7 are fixed, and the screw 7 is fixed to the sole 1. After using for a certain period of time, the cover body 8 is loosened to disengage the limiting strip 504 and the limiting groove 505 between the upper and lower seats 503, and the lower seat 503 is rotated to a certain position and the cover body is tightened again, and the first elastic rib 501 can realize the position conversion. In this embodiment, the insertion rod can still be set on the upper seat 502, but with certain adaptive modifications, such as setting the insertion rod to an inverted T-shaped structure and inserting it into the insertion hole 401 from the lower surface of the upper seat 502.

[0031] In the above embodiment, referring to Figure 8 As shown, one side of the limit strip 504 of the upper seat 502 and the lower seat 503 includes an inclined surface or an arc surface, and the other side is a vertical surface. The vertical surface of the upper seat 502 cooperates with the vertical surface of the lower seat 503. The setting position of the vertical surface makes it possible for the upper seat 502 and the lower seat 503 to interact with each other when the lower seat 503 rotates relative to the upper seat 502 in the torque direction of the first member 5, and the inclined surface or arc surface of the limit strip of the lower seat 503 and the upper seat 502 interact with each other when the lower seat 503 rotates relative to the upper seat 502 in the opposite direction of the torque direction of the first member 5. In this embodiment, the cover body is arranged at the center of the first member 5, and the limit strip 504 is a certain distance away from the cover body. The lower seat 503 is made of elastic material. By rotating in the opposite direction of the torque, the lower seat 503 is elastically deformed downward. At the same time, the arc surface of the limit strip 504 cooperates with the rotation to adjust the position of the first elastic rib 501, so as to avoid the single first elastic rib 501 from eccentric wear. This embodiment is more convenient to use.

[0032] The present invention also includes a multifunctional walking-aid shoe, comprising the upper and the sole 1.
