Abstract

The present invention relates to a production method of an insole for shoes and, more particularly to a production method of an insole for shoes which can improve user convenience and body conformability by analyzing the shape and characteristics of a user′s feet. The method may include the steps of: (a) scanning the bottom of the foot three-dimensionally or manufacturing a frame corresponding to the shape of the foot; (b) measuring a relative pressure at a point contacting the ground and the order of contact with the ground while the user is walking or running; (c) forming the insole correspondingly to the shape of the foot according to step (a); and (d) while step (c) is performed, forming the insole by correcting with cushion depending on the relative pressure and the order of contact with the ground based on the measurement information obtained from step (b). The manufactured insole allows the user to feel less fatigue while walking and to lower the possibility of causing blisters while walking a long distance.

Description

[0001] The present invention relates to a method for manufacturing a shoe insole,

The present invention relates to a shoe field, and more particularly, to a method of manufacturing a custom shoe insole for analyzing a user's foot shape and a user's foot specificity to achieve convenience and body suitability of the wearer.

People feel fatigued when they walk or run for a long time. It is also common for blisters to be caught while walking on shoes that do not fit the wearer's feet. If you wear shoes that do not fit your feet for a long time, your feet may be deformed.

In order to solve this problem, a method of manufacturing an insole of a shoe by making a mold conforming to a foot shape using a gypsum, or a method of manufacturing an insole of a shoe corresponding to the shape by scanning the foot shape by three-dimensional scanning has been devised.

However, in the case of manufacturing the insole of a shoe by making a mold using only gypsum, it is possible to manufacture the insole of the shoe corresponding to the shape of the foot. However, when the wearer wears shoes with an insole adapted to the shape of the foot, There is a problem that characteristics are not considered. In addition, even when the insole of a shoe corresponding to the shape is manufactured by scanning the foot shape three-dimensionally, only the process requiring the same time as the process of manufacturing the mold using only the gypsum can be avoided, Problems arising in the insole of shoes still exist.

Therefore, there is still a need for shoes that not only conform to the shape of the wearer ' s feet but also meet the user's walking and running characteristics.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method of manufacturing an insole of a shoe that conforms not only to the shape of the wearer's foot but also to the wearer's walking and running characteristics .

In order to achieve the above and other objects,

A method of manufacturing a custom shoe insole,

(a) scanning the sole of the subject's foot three-dimensionally or making a mold conforming to the foot shape;

(b) measuring a relative pressure magnitude at a point of contact between the floor surface and the order in which the foot contacts the floor surface while the wearer is walking or running;

(c) shaping the insole of the shoe according to the shape of the target foot according to the step (a); And

(d) simultaneously with step (c), shaping the insole by cushioning according to the order of touching the feet and the bottom surface of the wearer and the relative pressure magnitude based on the measurement information obtained through the step (b) The method of manufacturing a custom shoe insole is characterized by comprising:

According to the present invention, in the step (d), the cushion is shaped in order and proportionally according to the order of the feet of the wearer contacting the ground and the magnitude of the pressure.

The customized shoe insole produced by the method according to the present invention allows the wearer of the shoe to walk with little fatigue and considerably reduce the possibility of blistering during long distance travel.

Fig. 2 is a view showing the shape of a mold conforming to the shape of the sole of a wearer made by a means such as a gypsum.
FIG. 3 is a view illustrating an example of a process of finding the order of touching the sole on the floor contact surface and the relative pressure magnitude when the wearer walks or tries to wear the shoe.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to the following illustrative drawings.

Fig. 1 shows an example of a process for raising a mold conforming to the shape of the wearer's foot using gypsum or the like, and Fig. 2 shows a state of the mold conforming to the shape of the soles of the wearer, FIG. 3 illustrates an example of a process of determining the order of pressing the feet against the floor contact surface and the relative pressure magnitude when the wearer walks or tries to wear the shoes, and FIG. The relationship between the insole of the manufactured shoe and the foot of the wearer is illustrated.

The insole of a shoe according to the present invention is manufactured in the following order.

First, for example, the foot of the applied target is scanned three-dimensionally to obtain foot shape information.

There are various kinds of equipments for three-dimensionally scanning the sole of the target foot, i.e., three-dimensionally.

The foot shape information obtained by the 3D scanner is transmitted to a computer and stored.

Another example of a method of obtaining foot shape information is a method of making a mold by drawing a foot pattern of a target to be worn using a means such as a gypsum as shown in Fig.

Then, the wearer walks or leaps on the pressure recognizing device as shown in Fig. 3 to check the order in which the wearer touches the floor during the walk and measures the relative pressure magnitude at the contact point with the floor surface.

The relative pressure at the point of contact between the feet and the bottom surface of the foot is closely related to the normal behavior of the pedestrian and the fatigue of the foot portion first contacting the bottom surface is checked, In addition to the structure conforming to the foot shape, the portion with high possibility of receiving a lot of fatigue is corrected by a separate cushion member, thereby allowing the shoe wearer to feel less fatigue.

At this time, according to the order of the wearer's foot contact with the ground, the cushion member is most likely to be placed in the first contact portion where the thickness of the cushion member is different. Also, as described above, the thickness of the cushion member varies with the foot portion having a high pressure when the foot is brought into contact with the floor surface. At this time, the foot portion with the greatest pressure causes the cushion to enter the most. Especially, when the foot part touching the ground at first and the pressure at that time are considered at the same time, the insole of the shoe is manufactured so that the cushion is further inserted.
