Description

Technical Field

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

[0002] The arch of the foot is a crucial structure for walking and standing. The arch of the foot is categorized as flat, normal, and high-arched. The difference in arch size is relatively small compared to foot length, and the arches of the left and right feet may be asymmetrical. Furthermore, the arch of the foot changes dynamically during walking.

[0003] Among various arch shapes, flat feet are a common condition. Studies have found that the prevalence of functional flat feet in preschoolers aged 3-6 is approximately 44%; in students aged 7-12, it is approximately 56.1%; and in students aged 13-16, it is approximately 54.27%. Generally speaking, functional flat feet typically develop in children before the age of 10, and some may persist into adulthood. The abnormal posture of flat feet can alter foot kinematics, leading to abnormalities in the locomotor system.

[0004] Research has found that flat feet can lead to chronic excessive tibial internal rotation, causing medial tibial stress syndrome (MTSS), which can further contribute to knee conditions such as femoropatellofemoral pain syndrome. Due to dysfunction of the posterior tibial muscles, gait is common, leading to pain in the heel, plantar fascia, and metatarsophalangeal joints. Prolonged, long-distance running can also alter the morphology of the medial longitudinal arch.

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

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

[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.

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

[0013] Optionally, in the above-mentioned arch adjustment system, the first connecting edge and the second connecting edge are arranged along a direction from the toe of the sole structure to the heel of the sole structure.

[0014] Optionally, in the above-mentioned arch adjustment system, the arch area is a groove structure that is recessed away from the flexible support pad, and the flexible support pad can be partially embedded in the groove structure.

[0017] a traction component, the traction component being movable relative to the sole structure, and one end of the traction component being 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 and the second connecting component are detachably connected.

[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 engaged 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, thereby changing the position of the first connecting edge relative to the second connecting edge. Since the flexible support pad has a first connecting edge and a second connecting edge and the second connecting edge is connected to the sole structure, the change in the position of the first connecting edge relative to the second connecting edge enables the flexible support pad to produce flexible deformation, so that the structure of the flexible support pad is changed, thereby producing different states of support for the human arch.

[0035] The utility model discloses a foot arch adjustment system to meet different foot arch support requirements. The utility model 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 embodiments described 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 making creative efforts 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, the sole structure 400 having 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, thereby changing the position of the first connecting edge 201 relative to the second connecting edge 202. Since 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 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 different states of support for the human arch of the foot. 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 of the foot, so as to dynamically adjust the support for the human arch of the foot, thereby meeting the support requirements of different arches of the foot.

[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 human arch of the foot of different people and ensure the support needs of the human arch of the foot of different people.

[0041] Furthermore, the inventors of the utility model have found that existing treatments for flat feet are essentially single hard supports, which only treat the symptoms and not the root cause. Flat feet in most people are functional and reversible, with the arch height changing with weight bearing. For example, the arch is significantly flat when standing, but normal when not weight bearing 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 utility model inventor's research also found that flat feet are mainly caused by the muscles that maintain the arch of the foot, such as the tibialis anterior, tibialis posterior, peroneus longus, long flexor muscles, flexor digitorum longus and other plantar muscles attached to the calf and ankle joints. The weak strength and reduced muscle activation level cause muscle tension imbalance. 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 exercised, 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 of the foot can be suspended in the air, meeting the support requirements for the arch of the foot during muscle exercise (without supporting the arch of the foot).

[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 it ensures that 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 in a 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 apart, 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), wherein the first edge 411 is the edge of the arch region 410 close to the toe of the sole structure 400, the second edge 412 is the edge of the arch region 410 close to the lateral side of the sole structure 400, the third edge 413 is the edge of the arch region 410 close to the heel of the sole structure 400, and the fourth edge is the edge of the arch region 410 close to the medial 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 connecting component 110, a traction component 120, and an adjustment component 150. The support pad connecting component 110 is connected to the first connection edge 201; the traction component 120 is movable relative to the sole structure 400, with one end of the traction component 120 connected to the support pad connecting component 110; and the adjustment component 150 is fixed relative to the sole structure 400, 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 adjust the length from one end of the traction component 120 to the adjusting component 150 by winding or stretching, thereby driving the first connecting edge 201 to move through the support pad connecting component 110.

[0055] In this embodiment, the adjustment mechanism 100 further includes a first connecting member 140 fixed relative to the adjustment member 150, and the sole structure 400 includes a second connecting member 430. The first connecting member 140 and the second connecting member 430 are detachably connected. The second connecting member 430 may be a plug-in slot, and the first connecting member 140 can be plugged into and engage with the second connecting member 430 to secure the adjustment member 150 relative to the sole structure 400.

[0056] The adjustment member 150 can be located at the rear end of the sole structure 400 (near the heel), or on the outside of the sole structure 400 to facilitate movement of the outside of the shoe for adjustment. It can also be located above the sole structure 400 so that it can be located inside the shoe when the sole structure 400 and the upper structure are connected to form the shoe.

[0057] The adjustment member 150 can be manually operated, such as by rotating it to wind the wire or rope (traction member 120). Alternatively, it can be electrically operated, such as by including a drive motor to wind the wire or rope (traction member 120). A mechanical structure, such as a transmission assembly, can also be provided to wind or stretch the traction member 120, thereby adjusting the position of the first connecting edge 201 relative to the second connecting edge 202.

[0058] To facilitate the movement of the traction member 120, the adjustment mechanism 100 further includes a guide structure 130. The guide structure 130 is fixed relative to the sole structure 400, and the traction member 120 and the guide structure 130 are slidably engaged. In this embodiment, the guide structure 130 is specifically a hose. Alternatively, the guide structure 130 may be configured as a groove structure having a guide groove.

[0059] In the arch adjustment system provided by this embodiment of the present invention, the sole structure 400 includes a guide groove. The guide structure 130 is a flexible member that fits within the guide groove. Specifically, the guide groove defines the path (orientation) of the traction member 120. When the guide structure 130 is embedded within the guide groove, its structure remains fixed, allowing the traction member 120 to slide along the guide path of the guide groove in a sliding engagement with the guide structure 130.

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

[0061] To facilitate processing, the sole structure 400 further includes a guide rail structure 420, with which the traction member 120 slidably engages. This arrangement allows the guide rail structure 420 and the main body of the sole structure 400 to be processed separately and assembled to complete the sole structure 400. The guide rail structure 420 can be assembled with the main body of the sole structure 400 to form a portion of the aforementioned guide channel. The guide rail structure 420 is preferably fixedly connected to the main body of the sole structure 400 by gluing or other methods.

[0062] To facilitate flexible deformation of the flexible support pad 200, the flexible support pad 200 has a first surface and a second surface, with the first surface facing away from the sole structure 400 and the second surface 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, thereby dividing the flexible support pad 200 into a plurality of sequentially connected flexible sub-pad portions 210. Specifically, as the height of the flexible support pad 200 protruding away from the flexible support pad 200 increases, the width of the grooves 220 decreases, and two adjacent flexible sub-pad portions 210 become relatively closer. As the height of the flexible support pad 200 protruding away from the flexible support pad 200 decreases, the width of the grooves 220 increases, and two adjacent flexible sub-pad portions 210 become relatively farther apart.

[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 through 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 member 110 has a first end and a second end, the first end facing the outside of the sole structure 400 and the second end connected to the traction member 120. The cross-sectional area of ​​the support pad connecting member 110 increases from the first end to the second end.

[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 an arch adjustment system as described above. 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. 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 will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily 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.
