Description

Technical Field

[0001] The present invention relates to the technical field of arch equipment, and in particular to an arch adjustment system and shoes. Background Art

[0002] The arch of the human foot is a key structure for maintaining walking / standing. The human arch of the foot is divided into: flat foot, normal foot and high arch foot. The difference in the arch of the foot of people is relatively small compared to the length of the foot, and the arch of the left and right feet of each person may be asymmetrical. And the arch of the foot also changes dynamically during the walking process.

[0003] Among various arch forms, flat feet is a common phenomenon. Studies have found that the incidence of functional flat feet in preschool children aged 3-6 is about 44%; the incidence of flat feet in students aged 7-12 is about 56.1%; and the incidence of flat feet in 13-16 years old is about 54.27%. Generally speaking, functional flat feet usually occur in children before the age of 10, and some will continue into adulthood. The abnormal posture of flat feet will produce changes in foot kinematics, leading to abnormalities in the motor system.

[0004] Studies have found that flat feet may lead to long-term excessive internal rotation of the tibia, which can cause medial tibial stress syndrome (MTSS), and then affect knee joint diseases such as femoral patellar pain syndrome. Due to the dysfunction of the posterior tibial muscles of the foot, it is common to walk with a figure-eight step, which can lead to pain in the heel, plantar fascia, and metatarsophalangeal joints. Long-term and long-distance running will cause changes in the morphology of the medial longitudinal arch to a certain extent.

[0005] However, the height of the arch of the foot varies greatly among different groups of people, and the support requirements for the arch of the foot are also different under different human movement patterns.

[0006] Therefore, how to meet different arch support requirements is an urgent problem to be solved by people in this technical field. Summary of the invention

[0007] In view of this, the present invention provides an arch adjustment system to meet different arch support requirements. The present invention also provides a shoe having the arch adjustment system.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0012] An adjustment mechanism is connected to the first connection edge and can adjust the position of the first connection edge relative to the second connection edge; when the position of the first connection edge relative to the second connection edge is different, the structure of the flexible support pad is different.

[0017] A traction component, the traction component moves relative to the sole structure, and one end of the traction component is connected to the support pad connecting component;

[0018] An adjusting component is fixed relative to the sole structure, connected to the other end of the traction component and capable of adjusting the length from one end of the traction component to the adjusting component.

[0019] Optionally, in the above-mentioned arch adjustment system, the adjustment mechanism further includes a first connecting component fixed relatively to the adjustment component, the sole structure has a second connecting component, and the first connecting component is detachably connected to the second connecting component.

[0020] Optionally, in the above-mentioned arch adjustment system, the adjustment mechanism further includes a guide structure, the guide structure is fixed relative to the sole structure, and the traction component is slidably matched with the guide structure.

[0021] Optionally, in the above-mentioned arch adjustment system, the sole structure has a guide groove body, and the guide structure is a flexible member and can be embedded in the guide groove body.

[0022] Optionally, in the above-mentioned arch adjustment system, the sole structure further has a guide rail structure, and the traction component is slidably matched with the guide rail structure.

[0025] The present invention also provides a shoe, comprising an upper structure and an arch adjustment system as described in any one of the above items, wherein the sole structure of the arch adjustment system is connected to the upper structure.

[0026] It can be seen from the above technical solutions that the arch adjustment system provided by the present invention adjusts the position of the first connecting edge through an adjustment mechanism, so that the position of the first connecting edge relative to the second connecting edge is changed.

[0035] The invention discloses a foot arch adjustment system to meet different foot arch support requirements. The invention also provides a shoe with the foot arch adjustment system.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1 As shown, an embodiment of the present invention provides an arch adjustment system, including a sole structure 400, a flexible support pad 200 and an adjustment mechanism 100, wherein the sole structure 400 has an arch area 410 corresponding to the human arch; the flexible support pad 200 is located in the arch area 410 and is used to support the human arch, the flexible support pad 200 has a first connecting edge 201 and a second connecting edge 202, and the second connecting edge 202 is connected to the sole structure 400; the adjustment mechanism 100 is connected to the first connecting edge 201 and can adjust the position of the first connecting edge 201 relative to the second connecting edge 202; when the position of the first connecting edge 201 relative to the second connecting edge 202 is different, the structure of the flexible support pad 200 is different.

[0038] The arch adjustment system provided by the embodiment of the present invention adjusts the position of the first connecting edge 201 through the adjustment mechanism 100, so that the position of the first connecting edge 201 relative to the second connecting edge 202 is changed. Since the flexible support pad 200 has the first connecting edge 201 and the second connecting edge 202 and the second connecting edge 202 is connected to the sole structure 400, the change in the position of the first connecting edge 201 relative to the second connecting edge 202 enables the flexible support pad 200 to produce flexible deformation, so that the structure of the flexible support pad 200 is changed, thereby providing support for the human arch in different states. In actual use, the arch adjustment system provided by the embodiment of the present invention can be used to adjust the support effect on the human arch, so as to dynamically adjust the support effect on the human arch, thereby meeting the support requirements of different arches.

[0039] The structural changes of the flexible support pad 200 include stretching and flexing, thereby forming an arch or flattening, thereby achieving dynamic adjustment of the human arch.

[0040] For example, by operating the adjustment mechanism 100 accordingly, the structure of the flexible support pad 200 can be different (the degree of bending of the flexible support pad 200 is different) so as to meet the height of the arch of the human foot of different groups of people and ensure the support needs of the arch of the human foot of different groups of people.

[0041] Moreover, the inventors have found that the existing treatment technology for flat feet is basically a single hard support, which is only a temporary solution. Flat feet in most people are functional changes, which are reversible. The height of the arch changes with or without weight bearing. For example, the arch is obviously low and flat when standing, and normal when not bearing weight or standing on tiptoes.

[0042] Therefore, the adjustment mechanism 100 can be operated accordingly according to the human body's movement form (such as standing, tiptoeing, weight-bearing or non-weight-bearing, etc.), so that the structure of the flexible support pad 200 undergoes corresponding bending changes to meet the support requirements for the arch of the foot under the corresponding movement form.

[0043] In addition, the inventors have also found that flat feet are mainly caused by the weak strength and reduced muscle activation level of the muscles that maintain the arch of the foot, such as the tibialis anterior, tibialis posterior, peroneus longus, long flexor, long flexor digitorum and other plantar muscles attached to the calf and ankle joints, which cause imbalance in muscle tension. Therefore, improving the muscle activity level and neuromuscular control around the ankle joint is the key to treating flat feet. The scientific healthy development of the arch of the foot should be: when the muscles need to be exercised, the arch of the foot should be suspended in the air, and the arch of the foot should be supported during high-intensity exercise and muscle fatigue.

[0044] Therefore, when the muscles need to be trained, the adjustment mechanism 100 can be operated accordingly to make the structure of the flexible support pad 200 as flat as possible to ensure that the human arch can be suspended in the air and meet the support requirements for the arch during muscle training (without supporting the arch).

[0045] The sole structure 400 in this embodiment can be the midsole of a shoe. Of course, it can also be other structures, as long as the flexible support pad 200 can support the arch of the human foot.

[0046] Preferably, the first connecting edge 201 and the second connecting edge 202 are arranged along the direction from the toe of the sole structure 400 to the heel of the sole structure 400. When the first connecting edge 201 and the second connecting edge 202 are relatively close to each other, the height of the flexible support pad 200 protruding away from the sole structure 400 increases; when the first connecting edge 201 and the second connecting edge 202 are relatively far away from each other, the height of the flexible support pad 200 protruding away from the sole structure 400 decreases.

[0047] In order to improve the compactness and stability of the structure, the arch area 410 is a groove structure that is recessed away from the flexible support pad 200, and the flexible support pad 200 can be partially embedded in the groove structure. When the flexible support pad 200 is flattened, the flexible support pad 200 can be completely embedded in the groove structure.

[0048] like Figure 1 As shown, in some specific embodiments, the arch region 410 has a first edge 411, a second edge 412, a third edge 413 and a fourth edge (or does not have a fourth edge), the first edge 411 is an edge of the arch region 410 close to the toe of the sole structure 400, the second edge 412 is an edge of the arch region 410 close to the outer side of the sole structure 400, the third edge 413 is an edge of the arch region 410 close to the heel of the sole structure 400, and the fourth edge is an edge of the arch region 410 close to the inner side of the sole structure 400;

[0049] The second connecting edge of the flexible support pad 200 is connected to the third edge 413 , and the first edge 411 , the second edge 412 (and the fourth edge) and the flexible support pad 200 are movable relative to each other.

[0050] Preferably, the second connection edge of the flexible support pad 200 is fixedly connected to the third edge 413 by gluing.

[0051] In this embodiment, the flexible support pad 200 is a fan-shaped structure.

[0052] like Figure 1 and Figure 2As shown, the adjustment mechanism 100 includes a support pad connection component 110, a traction component 120 and an adjustment component 150. The support pad connection component 110 is connected to the first connection edge 201; the traction component 120 is movable relative to the sole structure 400, and one end of the traction component 120 is connected to the support pad connection component 110; the adjustment component 150 is fixed relative to the sole structure 400, and the adjustment component 150 is connected to the other end of the traction component 120 and can adjust the length from one end of the traction component 120 to the adjustment component 150.

[0053] In this embodiment, the traction component 120 is a line or a rope, such as a BOA line or a rope made of other materials.

[0054] The adjusting component 150 can be connected to the other end of the line or rope and the length from one end of the traction component 120 to the adjusting component 150 can be adjusted by winding or stretching, thereby driving the first connecting edge 201 to move through the supporting pad connecting component 110.

[0055] In this embodiment, the adjustment mechanism 100 further includes a first connection component 140 fixed relatively to the adjustment component 150, and the sole structure 400 includes a second connection component 430, and the first connection component 140 is detachably connected to the second connection component 430. The second connection component 430 may be a plug-in slot, and the first connection component 140 can be plugged into and matched with the second connection component 430 to achieve the fixing of the adjustment component 150 relative to the sole structure 400.

[0056] The adjustment component 150 may be located at the rear end of the sole structure 400 (close to the heel), or at the outside of the sole structure 400, so as to move the outside of the shoe and make corresponding adjustments. The adjustment component 150 may also be arranged above the sole structure 400, so as to be located inside the shoe when the sole structure 400 is connected to the upper structure to form the shoe.

[0057] The adjusting member 150 may be manually operated, such as rotating to wind the wire or rope (traction member 120). It may also be electrically operated, such as including a driving motor for winding the wire or rope (traction member 120). A mechanical structure, such as a transmission assembly, may also be provided to achieve operations such as winding or stretching the traction member 120, so as to adjust the position of the first connection edge 201 relative to the second connection edge 202.

[0058] In order to facilitate the movement of the traction component 120, the adjustment mechanism 100 further includes a guide structure 130, which is fixed relative to the sole structure 400, and the traction component 120 and the guide structure 130 are slidably matched. In this embodiment, the guide structure 130 is specifically a hose. The guide structure 130 can also be set as a groove structure with a guide groove.

[0059] In the arch adjustment system provided by the embodiment of the present invention, the sole structure 400 has a guide groove body, and the guide structure 130 is a flexible member and can be embedded in the guide groove body. That is, the guide groove body determines the moving path (direction) of the guiding traction component 120, and the guide structure 130 is fixed in the state of being embedded in the guide groove body, so that the traction component 120 can move along the guiding path of the guide groove body in the state of sliding cooperation with the guide structure 130.

[0060] Of course, the guide structure 130 may also be configured as a hard component to directly guide the moving path (direction) of the traction component 120 through the structure of the guide structure 130 .

[0061] In order to facilitate processing, the sole structure 400 further has a guide rail structure 420, and the traction component 120 is slidably matched with the guide rail structure 420. Through the above arrangement, the guide rail structure 420 and the body of the sole structure 400 can be processed separately and the sole structure 400 can be completed by assembly. The guide rail structure 420 can be assembled with the body of the sole structure 400 to form a part of the above guide groove body. The guide rail structure 420 is preferably fixedly connected to the body of the sole structure 400 by gluing or the like.

[0062] In order to facilitate the flexible deformation of the flexible support pad 200, the flexible support pad 200 has a first surface and a second surface, the first surface is facing away from the sole structure 400, and the second surface is facing the sole structure 400; the second surface has a plurality of grooves 220 arranged along the arrangement direction of the first connecting edge 201 and the second connecting edge 202, so as to divide the flexible support pad 200 into a plurality of sequentially connected flexible sub-pad portions 210. That is, as the height of the protrusion of the flexible support pad 200 facing away from the flexible support pad 200 increases, the width of the groove 220 decreases, and two adjacent flexible sub-pad portions 210 are relatively close. As the height of the protrusion of the flexible support pad 200 facing away from the flexible support pad 200 decreases, the width of the groove 220 increases, and two adjacent flexible sub-pad portions 210 are relatively far away.

[0063] Of course, the first surface and the second surface of the flexible support pad 200 may also be set as flat surfaces, and the structural change of the flexible support pad 200 is achieved only by the flexible deformation of the material of the flexible support pad 200 .

[0064] The flexible support pad 200 can be made of an elastic flexible material to further improve the comfort of use.

[0065] In this embodiment, the support pad connecting component 110 has a first end and a second end, the first end faces the outside of the sole structure 400, and the second end is connected to the traction component 120. From the first end to the second end, the cross-sectional area of ​​the support pad connecting component 110 increases.

[0066] Furthermore, the second surface has an embedded groove near the first connection edge 201, and the support pad connection component 110 is embedded in the embedded groove. In addition, the support pad connection component 110 and the flexible support pad 200 can be fixedly connected by gluing or other methods.

[0067] A shoe provided by an embodiment of the present invention includes an upper structure and also includes any one of the above-mentioned arch adjustment systems, wherein the sole structure 400 of the arch adjustment system is connected to the upper structure.

[0068] Since the above-mentioned arch adjustment system has the above-mentioned technical effects, the shoes having the above-mentioned arch adjustment system should also have the same technical effects, and no specific restrictions are made here and they are all within the scope of protection.

[0069] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0070] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
