Problems solved by technology

In this way, although the insole is relatively close to the shape of the deformed foot, which brings a certain degree of comfort and correction effect, but this classification makes the production and sales quite complicated.
And for insoles, due to the large number of shoe sizes, making each shoe size into different types is equivalent to multiplying the complexity of the production and sales of insoles
On the other hand, this method of classifying deformed feet into three shapes and prefabricating the shapes ignores the deformed feet classified into one category such as excessively supinated feet. The degree of deformity of each person may still be inconsistent, and the shape of the sole of the foot may also vary. Will be the same, using one pre-made shape does not fit the shape varies despite belonging to a certain type of deformed foot such as hyperspinning the foot

Embodiment 1

[0039] Embodiment 1: as figure 2 and image 3 As shown, the self-adjustable insole of the present embodiment is provided with a fluid cavity (3), surrounded by the cavity wall (4), and the upper and lower walls of the cavity wall (4) constitute the two sides of the insole, which contains a small amount of of fluid (5). The self-adjustable shape insole of this embodiment has the entire length of the foot, and the cavity (3) is a connected whole. Fluid (5) accounts for less than 80% of the total volume of the fluid chamber (3), according to tests, preferably, the fluid (5) accounts for 10%-40% of the total volume of the fluid chamber (3), so that the fluid (5) is sufficient for Fill the gap between the original sole (1) and the ordinary insole; simultaneously when the pressure of the sole (1) acts on the insole, after the fluid (5) in the fluid chamber (3) reaches a relative balance, the fluid chamber (3) ) does not contain fluid (5) between the upper and lower walls of part...

Embodiment 2

[0040] Embodiment 2: as figure 2 , Figure 4 and Figure 5 As shown, the self-adjustable insole of the present embodiment is provided with a fluid cavity (3), surrounded by the cavity wall (4), and the upper and lower walls of the cavity wall (4) constitute the two sides of the insole, which contains a small amount of of fluid (5). The difference between this embodiment and embodiment 1 is that although the insole of self-adjusting shape still has the length of the whole foot, the fluid cavity (3) is divided into cavity (31) by toe, metatarsal head cavity (32), and arch cavity. (33), form with a sub-chamber or several disconnected sub-chambers of the cavity (34) with the heel. The advantage of this embodiment is that the above-mentioned four sub-chambers all correspond to a specific position on the sole of the foot. If a certain part of the user's sole of the foot is deformed, the fluid (5) in the sub-chamber at the corresponding position allows the insole (2) to form loca...

Embodiment 3

[0041] Embodiment 3: as figure 2 and Figure 6 As shown, the self-adjustable insole of the present embodiment is provided with a fluid cavity (3), surrounded by the cavity wall (4), and the upper and lower walls of the cavity wall (4) constitute the two sides of the insole, which contains a small amount of of fluid (5). The present embodiment is different from Embodiment 2 in that the fluid chamber (3) is divided into four chambers (31), the metatarsal head chamber (32), the arch chamber (33), and the heel chamber (34). cavities, and adjacent sub-cavities are communicated through connecting channels (6). Although the four independent sub-chambers can provide a relatively stable pressure relief effect for each part of the sole of the foot in a more targeted manner, this brings a certain degree of difficulty to production. It is necessary to determine the fluid that needs to be sealed inside for each independent chamber. (5) Amount. In this embodiment, the problem of comple...

Abstract

The invention discloses a shoe pad capable of adjusting self shapes, which comprises one or a plurality of fluid cavities filled with fluid, wherein the walls of the fluid cavities are made of elastic materials with damping function. The shoe pad is characterized in that the fluid cavities of the sole pad capable of adjusting self shapes contain a little of fluid for filling gaps between a sole and a common shoe pad, thus, a shoe pad in complete fit with the sole is obtained and the stressed area of the shoe pad is maximized. Based on the flowing feature of the fluid and the advantage that under the act of force, the fluid in the same cavity flows towards a part with less pressure in the cavity until pressures of all fluids in the cavity are equal, the sole can be acted by a uniform supporting force and users wearing the shoe pad can stand and work more comfortably.

Description

technical field [0001] The invention mainly relates to insoles in the field of daily necessities, in particular to a shape-adjustable insole. Background technique [0002] Ordinary insoles are generally relatively flat, but the soles of the feet are uneven, which makes some parts of the soles bear too much pressure, and some parts do not bear any pressure, which can easily cause discomfort or even pain in the stressed parts of the feet. Under a certain pressure, the larger the force-bearing area, the smaller the pressure. Under the certain weight of the human body, that is, the larger the area of ​​the sole contacting the insole, the smaller the pressure on the stressed part, and the easier it is to walk. comfortable. [0003] For above problem, the someone has made efforts to improving shoe-pad. As early as 1997, Steven Lyons designed the "foot-like insole or boot pad" (patent number #CN1233943), which designed a foot-like insole covering the sole or boot sole, including:...
