Description

Technical Field

[0001] The utility model relates to the technical field of corrective insoles, in particular to a hallux valgus corrective insole based on modular design. Background Art

[0002] Hallux valgus, also known as "bony hallux valgus" or "big hallux valgus", is a common foot deformity. The main manifestation of hallux valgus is that the base joint of the big toe protrudes outward, while the big toe itself deviates toward the other toes of the foot. This condition is usually accompanied by pain and discomfort when walking.

[0003] In recent years, as people pay more attention to foot health issues, the industry of hallux valgus correction products is booming. Currently, hallux valgus correction products on the market mainly include corrective insoles, orthotics, etc. Existing hallux valgus correction insoles are usually provided with thick protrusions on the sole of the foot, or with partitions or raised toe separators at the big toe, mainly using these protrusions or partitions and other structures to intervene in the toes. However, on the one hand, these raised parts are difficult to squeeze into the toes and directly affect the toes, and the toes will move on the protrusions during exercise, affecting the correction effect. On the other hand, most of these corrective insoles can only be customized and special pads are used for special purposes, and the versatility is poor. Currently, most common hallux valgus correctors are products used independently in home scenes, including medical correctors (adjusting the tightness of the line through the side knob), strap-type correctors, and silicone toe-splitting trainers (including slipper-like forefoot correctors and correctors that fit between the fingers). The hallux valgus corrector is a relatively mainstream hallux valgus correction product. However, it is mostly used at home and cannot be used in public places or for daily commuting. As a non-daily necessity, users need to develop training habits to ensure the quality of correction.

[0004] At present, the modular design of insoles focuses on the combination of smart components and insoles, such as anti-lost shoes, heating shoes, massage shoes, and sole pressure sensor shoes. The core is to combine functional modules with insoles, and modules can be replaced or upgraded separately to achieve the addition of certain smart functions. Some modular insoles on the market are designed to fit the foot shape by stacking layers of materials, such as thickening the layers at the arch to provide support, assembling modules of different sizes to increase the fit of the foot, etc. In addition, some sweat-absorbing insoles also adopt a modular design, and the detachable and replaceable sweat-absorbing sheets are easy to disassemble and clean during use.

[0005] In short, the mainstream direction of modular insoles is the combination of smart components and insoles, and relatively few consider the shape of insoles from the perspective of foot health. To this end, we combined the hallux valgus trainer with the insole and developed a new modular corrective insole product. Users can use this product daily to train toe strength and correct toe shape at any time. Utility Model Content

[0006] The purpose of the utility model is to solve the problems of poor correction effect, poor versatility, and difficulty in daily use that are common in existing hallux valgus correction products, and to provide a hallux valgus correction insole based on modular design. The hallux valgus correction insole includes an insole body and a forefoot pad, a correction column is arranged on the forefoot pad, and matching holes are arranged on the insole body. The forefoot pad is located below the insole body, and the correction column passes through the holes to connect the insole body and the forefoot pad together, and the correction of the toes is achieved through these correction columns.

[0007] Furthermore, the number of the correction columns is the same as the number of the holes, and neither number exceeds 5.

[0008] Furthermore, the correction column includes a functional correction column and a non-functional correction column. The height of the non-functional correction column is equal to the height of the hole (i.e., the non-functional correction column is flush with the hole after passing through the hole), so as to fill the hole; the height of the functional correction column is greater than the height of the non-functional correction column (i.e., the end of the functional correction column protrudes outward after passing through the hole), and the protruding functional correction column can better correct the thumb.

[0009] Furthermore, the functional correction columns and non-functional correction columns on the forefoot pad are arranged in an orderly or random manner. The specific arrangement is as follows: Figure 7 shown.

[0010] Furthermore, 1-4 functional correction columns are arranged on the forefoot pad, and the corresponding number of non-functional correction columns is 3-0.

[0011] Furthermore, the functional correction column includes a correction column top and a correction column rod, wherein the correction column top is a mushroom shape with a smooth curve transition, and the correction column rod has a structural feature of being thin in the middle and thick at both ends so as to better fit between fingers.

[0012] Furthermore, the non-functional correction column includes a correction column head and a correction column rod, wherein the correction column head is flat and smooth, and the correction column rod has the same thickness from top to bottom. This design helps the non-functional correction column to better fill the hole on the forefoot pad.

[0013] Furthermore, the hallux valgus correction insole also includes a U-shaped protrusion. The U-shaped protrusion is arranged on the upper surface of the insole body and is located at the arch and heel.

[0014] Furthermore, the hallux valgus correction insole also includes an arch-deep heel cup support. The arch-deep heel cup has a U-shaped semi-enclosed structure and is arranged on the lower surface of the insole body.

[0015] Furthermore, the hallux valgus correction insole also includes an insole bottom, which is attached to the bottom of the insole body, and the forefoot pad and the arch-deep heel cup support are fixed between the insole bottom and the insole body to prevent them from falling off or slipping.

[0016] The advancement and beneficial effects of the utility model are mainly reflected in the following points:

[0017] (1) Through modular combination design and assembly, the hallux valgus correction insole can be prefabricated and semi-customized, which can meet the personalized needs of different users for hallux valgus correction with lower production cost and faster delivery speed, and solve the problem that hallux valgus trainers are difficult to integrate into daily wear.

[0018] (2) The above modular design has many advantages, mainly in terms of modular manufacturing and personalized rapid assembly. Through the selection and matching of a variety of forefoot pads, arch-deep heel cup supports, etc., it can meet the special needs of various foot problems. You only need to select the corresponding forefoot pad according to the toe to be corrected and replace it.

[0019] (3) During production, there is no need to manufacture separate molds for producing multiple styles of the entire insole, which effectively reduces production costs and pollution emissions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to enable ordinary technicians in the field to fully understand the technical solutions and beneficial effects of the utility model, further description is given below in conjunction with specific embodiments and drawings.

[0029] like Figure 1-7 The modular design of the hallux valgus correction insole shown in the figure mainly includes four parts: the insole body 1, the forefoot pad 2, the arch-deep heel cup support 3 and the insole bottom 4. The insole body 1 is made of breathable mesh + EVA material. Compared with ordinary insoles, it is wider at the forefoot and toes. Four elliptical holes 11 are set at the positions corresponding to the finger joints, and the arch part and the heel cup part are an integrated U-shaped structure (i.e., U-shaped protrusion 13), which is a ring-shaped protrusion, as shown in detail. Figure 3 shown.

[0030] The forefoot pad 2 is the core and key of the utility model. Its overall shape is similar to the shape of the forefoot of the foot. Four protrusions (i.e., correction columns) are arranged at the positions corresponding to the finger gaps. These protrusions are of two heights, namely functional correction columns (such as 22, 24, 25mm in height) and non-functional correction columns (such as 23, 25). The former can be used for toe correction, and the latter is mainly used for filling the hole 11. Taking the functional correction column 22 as an example, it includes a functional correction column top 221 and a functional correction column rod 222, wherein the functional correction column top 221 is a rounded shape similar to a mushroom, and the functional correction column rod 222 has a structure that is thin in the middle and thick at both ends, which helps to fit the finger gaps. Similarly, taking the non-functional corrective column 25 as an example, it includes a non-functional corrective column head 251 and a non-functional corrective column rod 252, wherein the non-functional corrective column head 251 is relatively flat and smooth, and the non-functional corrective column rod 252 has the same thickness from top to bottom, which is consistent with the shape of the holes 11 on the insole body 1, so as to better fill these holes.

[0031] Considering that different people have different hallux valgus conditions and need to correct different toes, a series of replaceable forefoot pads 2 are designed to meet personalized requirements. Figure 7 As shown in the figure, the black solid circles represent functional correction columns, and the hollow circles represent non-functional correction columns, covering 15 toe conditions that require correction.

[0032] The structure of the arch-deep heel cup support 3 is as follows Figure 5As shown in the figure, it is made of carbon fiber and fits the lower part of the insole body. The arch-deep heel cup support 3 has a U-shaped structure, which is wide at the arch and has a smooth tip at the outside of the foot. The whole body shape is composed of smooth curves. The arc-shaped bulge at the arch provides effective support, and the curve smoothly transitions to the heel in a bowl-shaped wrap. The deep heel cup design enhances stability and reduces impact. The arch-deep heel cup support 3 is divided into high arch shock-absorbing type, normal type, and flat foot support type for selection and replacement. The three types are similar in shape but have different arch heights.

[0033] The structure of the insole bottom 4 is as follows Figure 6 As shown, its appearance is similar to the insole body 1, but its area is slightly smaller than the latter. The insole bottom 4 is attached to the bottom of the insole to prevent the forefoot pad and the arch-deep heel cup support 3 from falling off. The insole bottom 4 is made of silica gel to ensure that the insole has good anti-slip ability in the shoe cavity.

[0034] The hallux valgus correction insole provided by the utility model accurately meets the toe correction needs of different consumers through a semi-customized forefoot pad, and the forefoot pad can be replaced at different correction stages to ensure the correction quality, and there is no need to manufacture molds separately for producing multiple styles of the entire insole during production. Considering that high arches or flat feet may be the cause of hallux valgus, an arch-deep heel cup support is provided, and consumers can choose the arch pad according to their own arch conditions, providing a high-fitting support for the foot and alleviating foot symptoms.

[0035] Compared with the traditional full-customization solution, this semi-customization solution has the advantages of low cost and high efficiency. Since the forefoot pad can be replaced at will, it can extend the product life cycle and reduce the pollution of discarded insoles. The hallux valgus correction insole can be produced by 3D printing, so that the forefoot pad and the insole body can achieve a higher fit, but the cost will be significantly increased and the production cycle will be longer.
