DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0023] Embodiment one The correction force provided by the conventional correction shoe is often one-time set and cannot be finely adjusted, which is difficult to adapt to the differentiated needs of the user for the orthopedic force in different correction stages. For example, in the initial, middle and late stages of correction, the required correction torque should be gradually increased, and the existing device lacks an effective phased and linear adjustment mechanism, resulting in that the correction process is either insufficient in strength and ineffective, or the initial strength is too large and causes discomfort, which limits the effectiveness and applicability of long-term correction, and the foot inversion and foot eversion are opposite deformity states, and their correction mechanics principles are also opposite, so it is difficult to realize one shoe for multiple uses.

[0024] As shown in Figures 1 to 7 As shown in Figure 14 and Figure 15 The correction shoe with foot inversion and eversion and claw toe correction functions comprises a shoe sole 1, a shoe upper 2, a shoelace 3 and an insole 9, further comprises a support part 4 arranged at the shoe opening inside the shoe upper 2, two correction assemblies 5 are arranged at the bottom of the two ends of the support part 4 in a symmetrical manner, a limiting part 41 is fixedly connected to the top of the support part 4, and the inside of the limiting part 41 is provided with adjusting assemblies 6 corresponding in position and in number to the correction assemblies 5. Through the cooperation of the adjusting assemblies 6 and the adjusting ropes 55, the tension of the adjusting belts 54 in the correction assemblies 5 can be adjusted.

[0025] The correction assembly 5 comprises a hollow member 51, the top of which is connected with the support part 4, and the bottom of which penetrates the vamp 2 and is connected with the sole 1.

[0026] An adjusting belt 54 is arranged inside the hollow member 51, the bottom of which is connected with the bottom of the insole 9 after penetrating the sidewall of the hollow member 51, and the top of which is connected with the adjusting assembly 6 through an adjusting rope 55; when the adjusting rope 55 is wound, the adjusting belt 54 is pulled to realize the progressive correction of the foot pronation or supination.

[0027] The adjusting assembly 6 is adjusted to wind the adjusting rope 55 and pull the adjusting belt 54 to realize the progressive correction of the foot pronation or supination.

[0028] The adjusting assembly 6 comprises a mounting member 61 connected with the limiting member 41, an accommodating cavity 62 is arranged in the mounting member 61, and a tightening groove 63 is arranged in the outer wall of the mounting member 61 and communicates with the accommodating cavity 62.

[0029] A rotating shaft 64 is arranged inside the accommodating cavity 62, one end of the rotating shaft 64 is rotatably connected with the mounting member 61, a winding roller 65 is fixedly arranged on the outer wall of the rotating shaft 64, and a limiting groove 66 is arranged in the rotating shaft 64.

[0030] A driving shaft 67 is slidably inserted into the limiting groove 66, a ratchet wheel 68 is fixedly connected to the outer wall of the driving shaft 67, and the other end of the driving shaft 67 is rotatably connected with the mounting member 61.

[0031] A fixing member 69 is fixedly arranged inside the accommodating cavity 62, a ratchet tooth 610 is rotatably connected to the fixing member 69 and matched with the ratchet wheel 68, and a first elastic member 611 is arranged between the outer side of the ratchet tooth 610 and the inner wall of the accommodating cavity 62.

[0032] One end of the adjusting rope 55 away from the adjusting belt 54 penetrates the limiting member 41 and the tightening groove 63 and is fixedly connected with the winding roller 65.

[0033] The end of the driving shaft 67 penetrating the mounting member 61 is fixedly connected with an adjusting cap 612, a second elastic member 613 is arranged between the inner wall of the adjusting cap 612 and the mounting member 61, the second elastic member 613 is sleeved on the outer wall of the driving shaft 67, an avoiding groove is formed between the fixing member 69 and the accommodating cavity 62, and the adjusting cap 612 of the two adjusting assemblies 6 is located on the outer side of the vamp 2.

[0034] When the adjusting cap 612 rotates, the rotating shaft 64 and the ratchet wheel 68 can be driven to rotate synchronously by the driving shaft 67, so that the winding roller 65 winds the adjusting rope 55, thereby pulling the adjusting belt 54. When the adjusting cap 612 stops rotating, the ratchet wheel 68 is limited by the engagement of the ratchet teeth 610. When the adjusting cap 612 is stretched outward, the second elastic member 613 can be stretched, so that the ratchet wheel 68 enters the avoidance groove and is disengaged from the engagement of the ratchet teeth 610. At this time, the adjusting belt 54 is reset, driving the rotating shaft 64 and the ratchet wheel 68 to reverse.

[0035] It should be noted that when the foot is corrected, as shown in Figure 14 and Figure 15 , by rotating the adjusting cap 612, the driving shaft 67, the rotating shaft 64 and the ratchet wheel 68 can be driven to rotate synchronously, so that the winding roller 65 winds the adjusting rope 55, thereby pulling the corresponding adjusting belt 54. By adjusting the tension of the insole and the outsole adjusting belt 54 respectively, and by the insole 9 acting on the sole, the abnormal posture of the foot can be corrected.

[0036] After wearing shoes, because the insole 9 is located between the sole and the shoe sole 1, and the two adjusting belts 54 are fixedly connected at the bottom of the insole 9, the foot bottom can be wrapped. At this time, when the tension of the outsole adjusting belt 54 increases, the lateral position of the foot bottom will be adjusted, and when the tension of the insole adjusting belt 54 increases, the medial position of the foot bottom will be adjusted.

[0037] Specifically, as shown in Figure 14 , when the foot is inverted, after wearing shoes, the whole shoe tends to turn inward, at this time, the tension of the outsole adjusting belt 54 can be increased to exert a righting force outward, effectively correcting the foot inversion state; conversely, as shown in Figure 15 , when the foot is turned outward, after wearing shoes, the whole shoe tends to turn outward, then the tension of the insole adjusting belt 54 can be increased to exert a righting force inward, thereby correcting the foot turning outward.

[0038] After the tension adjustment is completed, the adjusting cap 612 stops rotating, the ratchet wheel 68 is limited by the engagement of the ratchet teeth 610, effectively preventing reverse rotation, ensuring that the correction force is stable and continuous. When it is necessary to readjust or release the tension, the adjusting cap 612 can be stretched outward, so that the second elastic member 613 is stretched, and the ratchet wheel 68 enters the avoidance groove and is disengaged from the engagement of the ratchet teeth 610. At this time, the adjusting belt 54 is reset, driving the rotating shaft 64 and the ratchet wheel 68 to reverse, thereby realizing the rapid release of the tension and providing convenience for subsequent adjustment.

[0039] The support part 4 is made of elastic fiber material, and two elastic bands 7 are arranged on the support part 4 in a staggered manner to fix the support part 4.

[0040] The support part 4 is made of elastic fiber material, and the purpose is that, since both the foot inversion and the foot eversion occur below the ankle, by pulling the support part 4 to adjust the height, the position of the elastic band 7 when fixing the support part 4 can be ensured to be above the ankle, facilitating the adjustment of the adjusting band 54 during the correction of the foot inversion or the foot eversion.

[0041] In actual use, first, the correction shoe is worn on the foot, and the support part 4 is pulled upward to be stably wrapped above the ankle. Then, according to the specific symptoms of the existing foot inversion or foot eversion of the user, the adjusting cap 612 on the corresponding side is rotated, the adjusting cap 612 drives the driving shaft 67 to rotate, and then the winding roller 65 is synchronously rotated through the rotating shaft 64, so as to realize the winding operation of the adjusting rope 55. With the winding of the adjusting rope 55, the corresponding adjusting band 54 is pulled, and the tension is adjusted. By respectively controlling the tension of the insole and the outside adjusting band 54, the abnormal posture of the foot can be corrected in a targeted manner. Specifically, when there is foot inversion, the shoe body as a whole tends to tilt to the inboard side, and at this time, by increasing the tension of the outside adjusting band 54, a continuous righting moment is applied to the outside of the foot through the insole 9, so as to effectively correct the inversion state of the foot; conversely, if it is foot eversion, by increasing the tension of the inboard adjusting band 54, a righting moment is applied to the inboard side of the foot through the insole 9, so as to realize the eversion correction.

[0042] During the entire correction process, by accurately controlling the winding degree of the winding roller 65, linear adjustment of the correction force can be realized, and the differentiated needs for the size of the orthopedic force in different correction stages can be met. For example, in the middle and later stages of foot inversion correction, the tension of the outside adjusting band 54 can be further increased to improve the correction strength and adapt to further correction goals. Similarly, in the foot eversion correction process, the inboard tension can also be gradually increased to cope with the correction challenges in different stages. Such a phased and controllable correction mechanism significantly improves the adaptability range and effectiveness of long-term use of the correction shoe.

[0043] In summary, by the arrangement of the correction assembly 5 and the adjusting assembly 6, the rotation of the adjusting cap 612 causes the corresponding adjusting band 54 to be pulled with the winding of the adjusting rope 55, and the tension is adjusted. By respectively controlling the tension of the inboard and outside adjusting bands 54, the abnormal posture of the foot can be corrected in a targeted manner. During the entire correction process, by accurately controlling the winding degree of the winding roller 65, linear adjustment of the correction force can be realized, the differentiated needs for the size of the orthopedic force in different correction stages can be met, and the practicability is improved.

[0044] Embodiment Two The existing correction device is usually limited to correcting the force line of the foot in a single plane, such as the coronal plane, and can only adjust the inclination angle of the medial and lateral sides of the foot, and cannot solve the complex three-dimensional deformity problem from the overall biomechanics. In practice, foot inversion or foot eversion and other force line abnormalities often cause patients to compensate by flexing their toes and grabbing the ground while walking, which can easily lead to secondary claw toes, i.e. deformities in the sagittal plane. In addition, the support structure of the traditional correction insole is fixed in height and cannot be self-adapted to adjust according to the arch shape and walking state of different users.

[0045] Please refer to Figures 8 to 9 The insole 9 includes a body 91, which is provided with a support air bag 92 at the top of the arch, and a correction air bag 93 at the top of the toes, and a flow channel is formed in the body 91 to communicate the support air bag 92 and the correction air bag 93.

[0046] Further, the insole 9 is connected with a limiting plate 96 arranged in an arc shape at the top of the toes.

[0047] When the support air bag 92 is pressed during walking, the gas in the support air bag 92 can flow into the correction air bag 93 through the flow channel, so that the correction air bag 93 is inflated and the toes are lifted, thereby supporting and correcting the claw toes.

[0048] The elastic coefficient of the correction air bag 93 is higher than that of the support air bag 92, which is to avoid the influence of the inflation of the correction air bag 93 on the patient when the support air bag 92 is not pressed.

[0049] It should be noted that during use, the arch part presses the support air bag 92 during walking, and the gas flows into the correction air bag 93 through the flow channel, so that the correction air bag 93 is inflated and the toes are lifted for correction, which is suitable for the correction of claw toes. At the same time, the supporting force of the support air bag 92 is weakened to avoid high support to the arch, thereby preventing high arch. This design not only enables the insole 9 to correct the claw toes, but also adapts to the force of claw toe correction and arch support, corrects the inner eight feet, and avoids insufficient or excessive support.

[0050] In summary, the insole 9 of the present application is provided with the support air bag 92, the correction air bag 93 and the flow channel, which are cooperatively arranged to drive the gas to flow by using the pressure of the arch during walking, so that the correction air bag 93 is inflated in time and the toes are lifted for support. The structure realizes the active correction of the claw toes and the dynamic balance of the arch support force in the gait cycle through the pneumatic linkage and differential elasticity design between the air bags, effectively solves the technical defects of the traditional correction insole, such as the lack of correction function in the sagittal plane and the unadjustable support force, and significantly improves the adaptability and safety of the correction process.

[0051] Embodiment three Based on the above embodiments, in the phased correction of inversion or eversion of the foot, only the ankle can be strongly corrected, while the forefoot cannot be strongly and effectively corrected. At the same time, relying solely on the support airbag 92 set at the arch of the foot to correct claw toes results in a small degree of compression on the support airbag 92 due to the arch of the foot, and the correction effect is poor. The following improvements are made.

[0052] Please see Figures 10 to 13 The insole 9 includes a main body 91, with two supporting airbags 92 symmetrically arranged at the top arch, a corrective airbag 93 at the top toe, and two adjusting airbags 94 symmetrically arranged at the top heel. Both adjusting airbags 94 are connected to the corresponding supporting airbags 92 through guide holes 95.

[0053] The corrective airbag 93 can be connected to one or both of the inner and outer support airbags 92 via the flow channel connection adjustment component 8.

[0054] When performing foot inversion or foot eversion correction, the lateral support airbag 92 or the medial support airbag 92 is connected to the correction airbag 93 by adjusting the flow channel connection adjustment component 8 to achieve claw toe correction.

[0055] The flow channel connection adjustment component 8 includes a threaded hole 81, which is located between the support airbag 92 and the correction airbag 93 at the bottom of the body 91. It is connected to the correction airbag 93 and the two support airbags 92 through the flow channel 82. The flow channel connection adjustment column 83 is internally threaded. The flow channel connection adjustment column 83 has a first flow channel 831 connecting the outer support airbag 92 and the correction airbag 93, a second flow channel 832 connecting the inner support airbag 92 and the correction airbag 93, and a third flow channel 833 connecting the correction airbag 93 and the two support airbags 92, respectively, from low to high along the height direction.

[0056] In its initial, uncorrected state, the airbag 94 is in a natural, uncompressed state. For example... Figure 14 As shown and Figure 15 As shown, when performing foot inversion or foot eversion correction, for foot inversion correction, the depth of the flow channel connecting adjustment post 83 screwed into the threaded hole 81 is adjusted to connect the first flow channel 831 with the outer support airbag 92 and the correction airbag 93. Then, the outer adjustment component 6 is adjusted to adjust the tension of the adjustment band 54. For foot eversion correction, the depth of the flow channel connecting adjustment post 83 screwed into the threaded hole 81 is adjusted to connect the second flow channel 832 with the inner support airbag 92 and the correction airbag 93. By increasing the tension of the corresponding side adjustment band 54, a corrective force pointing in the direction of correction can be applied to the foot. At this time, the bottom of the heel will form a tight contact with the corresponding side adjustment airbag 94.

[0057] During walking, the heel strikes the ground first. In the case of a pronation gait, because the lateral support airbag 92 and the correction airbag 93 are connected during the pronation correction process, the lateral adjustment airbag 94 is also connected to the lateral support airbag 92. The lateral support airbag 92 is connected to the correction airbag 93 through the first flow channel 831. The outer side of the sole 1 contacts the ground first, and the corresponding adjustment airbag 94 is compressed. The adjustment airbag 94 can cushion the pronation walking, thus effectively improving comfort during walking. The compression of the lateral adjustment airbag 94 further enhances its cushioning effect. The internal gas flows through the guide hole 95 to the outer support airbag 92. The expansion of the support airbag 92 can apply a corrective force to the forefoot in the corrective direction. At the same time, some airflow enters the corrective airbag 93, causing the corrective airbag 93 to expand and lift the toes, thus providing support and correction for claw toes. As the forefoot falls, it will further compress the support airbag 92. After the support airbag 92 is compressed, the gas inside the support airbag 92 flows to the corrective airbag 93, and the corrective airbag 93 expands further to provide further support and correction for claw toes.

[0058] Conversely, such as Figure 11 As shown, in the case of a pronation gait, during the pronation correction process, the medial support airbag 92 and the correction airbag 93 are connected. At this time, the medial adjustment airbag 94 is connected to the medial support airbag 92. The medial support airbag 92 is connected to the correction airbag 93 through the second flow channel 832. The inner side of the sole 1 contacts the ground first. After the medial adjustment airbag 94 is compressed, the gas inside it flows through the guide hole 95 to the medial support airbag 92. The expansion of the medial support airbag 92 can apply a corrective force to the forefoot in the direction of correction. At the same time, some airflow enters the correction airbag 93, causing the correction airbag 93 to expand and lift the toes, thus supporting and correcting claw toes. As the forefoot falls, it further compresses the medial support airbag 92. After the medial support airbag 92 is compressed, the gas inside it flows to the correction airbag 93. The correction airbag 93 expands further to provide further support and correction for claw toes.

[0059] This invention achieves the following through the coordinated operation of the flow channel connecting the adjustment column 83, the support airbag 92, the correction airbag 93, the adjustment airbag 94, and the adjustment component 6: Firstly, it can provide strong inversion and supination correction at the ankle; secondly, it can simultaneously provide strong inversion and supination correction at the forefoot, thus providing overall inversion and supination correction for the entire foot; thirdly, it can inflate the correction airbag 93 to lift the toes, achieving support and correction for claw toes; and fourthly, as the forefoot descends, it can further support and correct claw toes.

[0060] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
