Description

All-wrapped sub-health correction shoe

Technical Field

The invention relates to a fully-wrapped type sub-health correcting shoe, in particular to a fully-wrapped type foot control correcting solution which comprehensively uses a correcting shoe and a special correcting insole thereof.

Background

According to statistics, about 20-30% of the population belongs to the flat feet, and people who generally suffer from the flat feet often have the phenomenon of hind foot eversion, namely, the heel bones tilt inwards, and the inclination angle is generally in direct proportion to the severity of the flat feet. There are 3 different classifications of flattening in medicine: a pseudoflat foot, a stiff flat foot, and a soft flat foot, wherein the pseudoflat foot is a common foot morphology for young children of 3 years old or less, generally without special treatment; the treatment mode of the hard flat foot is not suitable for insoles supported by the arch of foot, and the operation treatment is probably a more appropriate choice; soft flat feet are the most common shape of flat feet over five years of age to the adult stage, and are caused by more normal laxity of the ligaments of the foot and insufficient strength of the muscles of the arch, resulting in various degrees of sinking of the inner arch. For the child patient with soft flat foot, the traditional correction method mostly adopts a health care insole (such as an arch support, a heel support and the like) with arch support for treatment, and the health care insole is more suitable for the child with less severe flat foot, such as the hindfoot eversion angle is less than 8 degrees. The insole disclosed in chinese patent application CN103300539A filed by the same applicant belongs to the above health insole for correcting mild flat feet.

In addition, the hindfoot valgus/varus caused by severe flat foot or high arch foot can make the subtalar joint fail to play its normal function in gait cycle, causing various sequelae such as muscle pain, plantar fasciitis, etc., wherein the subtalar joint is the hindfoot central joint formed by the combination of three small joints between the talus and calcaneus, which is the pivot for keeping the foot stable, bears and conducts the body weight, and is the mechanical central axis of the hindfoot. For children with less severe flat feet, the heel inversion can be guided and the heel is finally vertical by using the flat foot health care insole in the prior art, but the children with more severe flat feet (the heel inversion angle is more than 8 degrees) often do not use the traditional health care insole only.

Detailed Description

The technical contents and constructional features of preferred embodiments of the invention, as well as the technical objects and technical effects achieved, are explained in detail below with reference to the accompanying drawings.

Fig. 1 is an exploded view of a fully wrapped foot control orthotic appliance incorporating an orthotic insole and an orthotic shoe according to an embodiment of the present invention. The inventor realizes the full-wrapping type foot control effect through the comprehensive use of the correcting insoles and the correcting shoes, and the main principle of the invention is that the correcting insoles provide arch support, heel positioning and heel inclination adjustment, and the special heel cup structure and the double-hardness sole design of the correcting shoes are added, so that the problem of severe flat feet or high-arch feet is effectively corrected. In addition, by means of the fully-wrapped foot control correction scheme, a child patient can achieve biological force line adjustment, abnormal positions of ankle joints are reduced, the tendency of internal rotation of knee joints and internal rotation of hip joints is reduced, and the possibility of generating foot and knee sequelae in the future is avoided.

As shown in FIG. 1, reference numeral 10 is a perspective view of an orthotic shoe with different types of orthotic insoles inside, using a fully wrapped foot control scheme, preferably the orthotic shoe 10 uses a mid-tube design to effectively control ankle level alignment while enhancing heel control to reduce hindfoot eversion and inversion. Optionally, the adjustable fastening tape positioned on the vamp is convenient to put on and take off and adjust the tightness, so that the full-wrapping type foot control effect is further ensured. Reference numeral 40 denotes a special correction insole used in cooperation with the correction shoe 10, and the correction insole 40 is not used in a conventional health insole, and is characterized in that a special heel positioning, arch support design, and heel slope adjustment are adopted, and according to the foot application of different children patients, the insole can be further divided into four types of V-shaped insoles (suitable for standard type severe flatfoot children), X-shaped insoles (suitable for obese type severe flatfoot children), Y-shaped insoles (suitable for thin type severe flatfoot children), and Z-shaped insoles (suitable for standard type high-arch foot children), and the comparison of the structural details between the different types of insoles will be further described in detail below. In the preferred embodiment of the present invention, the corrective shoe 10 and the corrective insole 40 are designed in a split type, and the inner space of the corrective shoe 10 can accommodate different types of corrective insoles 40 (i.e., VXYZ-type insoles), but it will be understood by those skilled in the art that the corrective shoe 10 and the corrective insole 40 are not limited to the split type design, and can be designed in an integrated type.

In order to achieve the desired full-range orthotic effect in combination with the orthotic shoe 10 described above, the inventors have developed an improved arrangement for the sole 20 and the inner heel cup 30 at the heel portion of the upper. The heel cup 30, together with the special orthotic insole 10, as shown, enables a fully wrapped foot control system with all-round heel locking and stable heel orthostatic orthotic. In summary, the heel cup 30 is designed to be long inside and short outside and the height of its inside end can cover the navicular bone, and functions to prevent the navicular bone from sinking and moving outward, and both sides fix the heel to a vertical position to reduce the heel valgus/varus. In addition, the sole 20 of the orthotic shoe 10 further employs a dual hardness sole material that is stiff inside and soft outside, reducing the chance of hindfoot eversion and inducing heel perpendicularity. Further details regarding the construction of the sole 20 and heel cup 30 will be discussed below with reference to the figures.

Fig. 2 is a schematic structural view of a double hardness sole 20 of an orthotic shoe according to an embodiment of the present invention. As shown in the front view of the outsole at the top of FIG. 2, the entire outsole of the sole 20 may be divided into two areas, an inner arch support area 21 and a non-inner arch support area 22, wherein the inner arch support area 21 is located on the inner side of the sole 20 and corresponds to the inner arch region of the foot anatomy, and the non-inner arch support area 22 corresponds to the other areas of the outsole outside of the inner arch support area 21. As shown, the line of demarcation between the medial arch support region 21 and the non-medial arch support region 22 is curved ergonomically in the arch region, and more importantly, the medial arch support region 21 on the medial side of the sole 20 is harder than the non-medial arch support region 22. In a typical athletic shoe design, the sole has a shore hardness of 55 degrees and the entire outsole is of uniform hardness to allow the outsole to flex easily for comfort, but in the present invention, the inventors have creatively used a dual hardness outsole configuration to create counter-forces in the medial arch support area to reduce the chance of hindfoot eversion to control the flat foot. Specifically, the sole material according to the embodiment of the invention is preferably made of a superplastic Ethylene (EVA) -ethylene vinyl acetate copolymer plastic raw material, and the EVA has the characteristics of good flexibility, not only has the elasticity as rubber, but also has good flexibility at-50 ℃. In the present invention, the EVA material of inner arch support region 21 is configured to have a Shore hardness of 70-60 degrees, preferably 65 degrees, while satisfying the condition that inner arch support region 21 has a hardness significantly higher than that of non-inner arch support region 22 (e.g., configured to have a Shore hardness of 55 degrees). Incidentally, Shore hardness (Shore Durometer) was proposed by Shore a.f. Shore in 1906, and is mainly used to measure the hardness of polymers, elastomers and rubbers, and is classified into three categories: a type, C type and D type, wherein the A type Shore hardness test method is the rubber hardness measuring means which has the longest use history and is widely applied, and the hardness of common polyurethane is 50, 70, 90 and the like. It will be understood by those skilled in the art that the higher the hardness of the EVA material, the greater its density, and therefore the density index may be used instead of the hardness index for measurement, thereby optionally designing a dual density outsole structure. This dual stiffness/dual density outsole structure is designed based on the basic principles of the anti-rearfoot valgus system (AVS), which effectively guides the heel vertically. It should be noted that the sole material is not limited to EVA, and other sole materials and combinations of different sole materials may be adopted as long as the dual hardness/dual density outsole structure is satisfied, such as a genuine leather sole, a rubber sole (RB), a polyurethane sole (PU), an MD sole, a TPR sole, a TPU sole, a PVC sole, a TR sole, a leather-like sole, a BPU sole, a cowhells sole, a PC sole, an ABS sole, and a PE sole.

Furthermore, as shown in the side view of the sole in the middle of fig. 2, the boundary between the inner arch support region 21 and the non-inner arch support region 22 in the thickness direction of the sole is designed to have a certain curvature according to the ergonomics of the arch part; as shown in the lower rear heel sectional view of fig. 2, the medial arch support region 21 and the non-medial arch support region 22 are combined together in a wedge shape in the width direction of the sole according to the ergonomics of the arch part. The combination of the curvature and the wedge-shaped interface meets the ergonomic requirements of the arch region on the one hand and helps to reduce the local stress concentration between the inner arch support region 21 and the non-inner arch support region 22 on the other hand, thereby improving the bonding strength between different parts of the outsole. In addition, the structural details of the non-medial arch support region 22, such as the start point, the first bone-covering grasping point, and the outsole flower, are not the focus of the present invention and are the same as the prior art, and thus the description thereof is omitted herein.

According to the rectification shoe of the embodiment of the invention, not only the double-hardness/double-density special outsole structure is obviously different from the constant-hardness/constant-density outsole structure in the prior art, but also the shoe inner heel cup is different from the shoe inner heel cup in the prior art, the shoe inner heel cup of the traditional sports shoe in the prior art is made of TPU material in an injection molding mode, the height of the shoe inner heel cup can not cover the navicular bone part so as to avoid rubbing the ankle part to influence the wearing comfort, and meanwhile, the lengths of the inner side and the outer side of the heel cup are approximately equal and are approximately more than one third and less than one half of the length of the whole sole. Fig. 3 is a schematic view showing a structure of an inner heel cup according to an embodiment of the present invention compared with that of an inner heel cup according to the prior art. Reference numeral 30' in fig. 3 shows the medial-lateral contour of the inner heel cup of the conventional sports shoe, and reference numeral 30 in fig. 3 shows the medial-lateral contour of the inner heel cup of the present invention. As shown in FIG. 3, the inner heel cup of the shoe according to the preferred embodiment of the present invention is designed to have an outer short and an inner long shape, and the ratio of the length of the outer side to the length of the inner side is about

1: 1.2-1: 1.5, and the length of the inner side exceeds half of the length of the sole, especially the length of the inner side further extends to a first bone covering part of the foot. In addition, the height of the front end part of the inner side of the heel cup in the shoe can cover the navicular bone, the functions of preventing the navicular bone from sinking and moving outwards are achieved, the heel is fixed to the vertical position at the two sides, and the probability of eversion/inversion of the heel is reduced. It should be noted that the contour of the heel cup in the shoe according to the invention takes on the special shape of the medial central depression (corresponding to the inner ankle) indicated by 30 in fig. 3, which is significantly different from the uniform circular arc contour of the heel cup in the shoe of the conventional sports shoe, since it is necessary to avoid rubbing the ankle portion while covering the navicular bone at the medial front end portion. As mentioned above, the special structure of the heel cup is used with the corrective insole described in detail below to achieve full wrap positioning of the heel and full heel locking of the insole, while shielding the navicular bone for control to stabilize the right position of the heel for controlling the foot joints and reducing strain.

Fig. 4 is a schematic structural view of a special corrective insole used in cooperation with a corrective shoe according to an embodiment of the present invention, which shows a front view, a rear view, and a perspective view of the special corrective insole 40, respectively, the special corrective insole 40 having a structure different from that of a conventional health care insole in the heel cup and the arch part so as to apply a force to the foot of a patient in a specific direction in the heel cup and the arch part in order to achieve a wrap-around corrective effect. The structural features of the heel cup cross section a and the arch cross section B will be described in further detail below in connection with the support and force state of the patient's foot.

Fig. 5A and 5B are schematic views showing the cross-sectional structures of the heel positioning and arch support parts of different types of orthotic insoles (V, Z, X, Y insoles) used in combination with orthotic shoes and the stress state of the foot according to an embodiment of the invention. Fig. 5A shows a sectional structure of a heel positioning part of various types of corrective insoles and a stress state of a foot, and fig. 5B shows a sectional structure of a corresponding arch support part and a stress state of a foot. As shown in the sectional structure views of fig. 5A and 5B, the special corrective insole according to the embodiment of the present invention is different from the conventional insole in that 1) a U-shaped lateral edge wrapping the heel from both sides is provided at the heel positioning part, and realizes all-directional heel locking together with the rear edge of the rear end of the insole (refer to the perspective view of fig. 4); 2) u-shaped lateral edges which respectively wrap the inner arch and the outer arch from two sides are arranged on the arch support part in the same way so as to stabilize the orthorectification of the heel; 3) for severe flat foot applications, the medial side of the heel region is higher than the lateral side, i.e., the heel region has a slope of about 6.5 degrees from the bottom surface to achieve heel slope adjustment. As shown in the stress state diagram, for standard severe flat-foot patients, the correcting insole according to the embodiment of the invention not only can support the heel part and the arch part from two sides, but also adds wedge-shaped inclination on the inner side of the heel of the insole, reduces the eversion amplitude when the heel lands, and leads the subtalar joint to be close to the neutral position; for patients with high arch, the heel socket of the orthotic insole according to embodiments of the invention remains arc-shaped, likewise reducing the extent of inversion when the heel is grounded, thereby bringing the subtalar joint closer to neutral.

For normal foot arch, the insole is made to fit the sole surface by adopting human engineering design, and the insole with proper hardness is selected to ensure the wearing comfort. However, for the severely flat/high arch child, the insole selection requires attention to the inner and outer arch support thickness and heel slope, in addition to softness, and proper inner and outer arch support and heel slope may prevent overstretching of the patient's pubic bone and reduce strain. As described above, the corrective insole of the present invention can provide four types of V-pad, Z-pad, X-pad and Y-pad, which are respectively applicable to different arch and heel conditions according to arch conditions (flat, ultra-wide flat, ultra-thin flat, high arch) of different patients, and are different from the fabrication structure of the conventional insole in arch and heel designs.

Specifically, the V-shaped pad is suitable for standard severe flatfoot children, and statistically accounts for 60% of all patients, and the V-shaped pad adopts the manufacturing structure shown in fig. 4A and 4B in the design of the arch part and the heel part, that is, the arch part adopts a general inner and outer arch support, the inner height of the heel part is higher than the outer height, for example, the inner slope of 6.5 degrees is designed, and the distance between two side edges of the arch part and the heel part is the arch width and the heel width of the standard type. The X pad is suitable for obese type severe flatfoot children, and is based on the V pad, the inner and outer arch supports are properly reduced, so that the width of the arch part is enlarged, the distance between two side edges of the rear root part is properly widened to be the width of an obese heel, and the inner inclination of the heel part is 6.5 degrees, for example. The Y-shaped pad is suitable for the thin and serious flatfoot children, and the inner and outer arch supports are respectively enlarged on the basis of the V-shaped pad, so that the width of the arch part is reduced, the distance between two side edges of the heel part is properly reduced to be the width of a thin heel, and the inner inclination of the heel part is 6.5 degrees, for example. The Z pad is suitable for standard high-arch children, the inner arch support and the outer arch support are respectively enlarged on the basis of the V pad, the enlarging amount of the Z pad is smaller than that of the Y pad, the distance between two side edges of the rear root position is properly reduced, the reducing amount of the Z pad is smaller than that of the Y pad, and the inner inclination design of the heel position is completely cancelled by the Z pad, so that the widths of the arch position and the heel position of the four kinds of insoles, namely the V pad, the Z pad, the X pad and the Y pad are different.

The specific parameters of the four types of insoles are not limited to those of the preferred embodiment, and are merely illustrative and not limiting. For example, the inclination of the heel area and the bottom surface of the VXY insole is not limited to 6.5 degrees, and can be any angle between 5.5-7.5 degrees and 5-10 degrees. In addition, the insoles with the same length and size are designed into the VXYZ four types, so that a user can conveniently select proper insoles according to the foot type of the user, and the comfort degree of the insoles is improved.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims. It is to be understood that the above description is intended to be illustrative, and not restrictive. For example, the above-described embodiments (and/or aspects thereof) may be used in combination with each other. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from its scope. Many other embodiments and modifications within the scope and spirit of the claims will be apparent to those of skill in the art from reading the foregoing description.
