Abstract

PURPOSE:To improve the balance of the pressure distribution of soles by forming the internal sides of toe sections to be made thicker than the external sides, to form the internal sides of heel sections to be made much thicker than the internal sides of the toe sections, and by forming upper surfaces in the shapes of oblique surfaces inclined to descend from the internal sides to the external sides and from the heel sections to the toe sections. CONSTITUTION:The internal sides 2 of toe sections 1 are formed to be made thicker than the external sides 4, and the internal sides 2 of heel sections 3 are formed to be made much thicker than the internal sides 2 of the toe sections 1, and upper surfaces are formed in the shapes of oblique surfaces inclined to descend from the internal sides 2 to the external sides 4 and from the heel sections 3 to the toe sections 1. As a result, the balance of the pressure distribution of skier's soles can be desirably improved. Besides, a device can be manufactured at a low cost with simplified mechanism and so it can be handily laid on skiing boots provided with no cant mechanisms to be used. Then the device can be properly used not only for the skiing boots but also for insoles for shoes for infants without formed foot arches, and insoles for shoes for exercise important for balance sense.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an insole for ski boots, which improves the sense of balance during exercise by installing the insole inside the ski boots. The present invention relates to an insole for ski boots that can be used.

[Prior Art] Conventionally, various types of ski boots have been equipped with a cant mechanism so as not to impair the user's sense of balance. In order to make this possible, there is a configuration in which a roughly plate-shaped sole called a canting combo sole is fixed to the sole of the boot. At the same time, the sole could be replaced with another one. In addition, by using plates such as arch plates, particle plates, fitting plates, etc., the user's feet are kept in complete contact with the ski boots, and the skier's sense of movement is not impaired. There is. Conventionally, ski boots have flat inner soles, but there are some special types that reproduce the shape of the user's foot to provide a better fit.

[What the invention seeks to solve] [E] Both in the ski boots equipped with the cant mechanism described in the prior art and in the attempts to increase the degree of adhesion between the ski boots and the foot using various plates, both of these points of view are A skier's sense of balance or movement is impaired by wearing ski boots.
The idea was to keep it as intact as possible.

By the way, skiing is said to be a sport that requires a greater sense of balance than other sports, and the skier's overall balance, including his posture and various movements, remains stable during high-speed exercise. It is necessary.

Therefore, this researcher completely disagrees with the above-mentioned idea of minimizing loss of the sense of balance or movement that would be impaired by skiers wearing ski boots, and decided to fundamentally improve balance. The present invention was arrived at based on the knowledge gained from various research and experiments based on the viewpoint that the amount of pressure applied to the entire sole of the skier's foot is extremely important in order for the skier's feet to remain stable continuously. The purpose is to provide an insole for ski boots that can satisfactorily improve the balance of pressure distribution on the soles of the feet of skiers wearing ski boots.

[Means for Solving the Problems] In order to achieve the above object, the insole for ski boots according to the present invention has an insole placed in the midsole of the ski boots, in which the inside of the forefoot is thicker than the outside. In addition, the inside of the hindfoot is formed thicker than the inside of the forefoot, so that the upper surface becomes an inclined surface that slopes downward from the inside to the outside and from the hindfoot to the forefoot. It is something.

[Operation] The operation of the present invention will be explained using the drawings. First, FIG. 1 is a diagram showing the distribution of equal pressure on the sole of a bare foot. Here, the equal pressure distribution map is calculated by dividing the total load determined by 8I by the total area of the sole of the foot, and calculating how many times the pressure value of each part of the sole of the foot is of the average pressure. This is a distribution map showing , and is also called the Noda type equal pressure distribution map. (Published by Shogakukan, co-authored by Yuji Noda and Hisao Ogawa)
) Also, refer to the school's creation will, "Hadabi no Susume") Also, the equal pressure distribution map shown in the figure.

As shown in the figure, in people with relatively unformed arches, the pressure distribution in the forefoot is concentrated at the base of the spring, and the pressure distribution is moderate in the hindfoot. It is clear that the kudzu has been stretched to the foot and is forming an elongated roughly circular shape. Figure 2 shows that the above-mentioned non-formed person was wearing ski boots with the insole for ski boots according to the present invention installed in the midsole. As is more cheerful than the equal pressure distribution map shown in Figure 0, the pressure distribution that was concentrated at the base of the buttock spreads over the entire forefoot, and the center of the pressure distribution moves to the center of the forefoot, and the pressure distribution in the hindfoot increases. The pressure distribution changed over time. Now, when observing the balance, compared to the equal pressure distribution diagram shown in Figure 1, the equal pressure distribution diagram shown in Figure 2 is
The load is held at the apex and base of the triangle, so the balance is good. Considering this, according to the insole for ski boots according to the present invention, since the inside of the forefoot is formed thicker than the outside,
It acts to spread the pressure distribution that was concentrated at the base of the foot to the outside and move the center of the pressure distribution to the center of the forefoot, and the inside of the hindfoot is thicker than the inside of the forefoot. As shown in Figure 1, the pressure that was previously applied to the hindfoot is transferred to the forefoot, strengthening the above-mentioned effect, and working to improve the pressure distribution in the hindfoot over time. As explained above, the insole for ski boots according to the present invention works to improve the pressure distribution on the sole of the foot and improve the balance.

[Example code] An embodiment according to the present invention will be described below.

First, FIG. 3 is a plan view of the insole for ski boots according to the present invention, and FIG. 4 is a left side view of the insole. Here, although FIGS. 3 and 4 show a ski boot insole for the left foot according to the present invention, the insole for the right foot is symmetrical with the insole for the left foot. Further, reference numerals 1.2.3.4 in FIGS. 3 and 4 refer to forefoot 1, medial 2,
As is clear from the figures, the shape of the insole 5 for ski boots according to the present invention is as follows:
The inner side 2 of the forefoot part 1 is thicker than the outer side 4, and the inner side 2 of the rear foot part 3 is formed even thicker than the inner side 2 of the forefoot part 1.

Next, seven skiers conducted a survey on a slope with one gate (skiing When we conducted a time test at a distance of 1,500 m), we found that the overall average was faster for 6 people, except for one person who was slower with the insole for Beski boots compared to the conventional one. 1.2
A reduction in seconds was seen. Also, according to the above skier,
Compared to conventional ski boots, the insole for ski boots allows for more balanced and stable operation of the skis, making it easier for the center of gravity to rest on the skis.

[Effects of the Invention] Since the present invention is configured as described above, it achieves the effects described below.

That is, the insole for ski boots according to the present invention has the effect of favorably improving the balance of pressure distribution on the soles of skiers' feet.

In addition, the insole for ski boots according to the present invention has a simple structure and can be manufactured at low cost, and can be easily installed and used in ski boots that do not have a cant mechanism, so it is extremely useful. It's also effective.

Since the insole for ski boots according to the present invention can improve the balance of pressure distribution on the sole of the foot, it can be used in addition to ski boots, insoles for shoes for infants with unformed arches, and for sports where a sense of balance is important. It is thought that it can also be suitably used as an insole for personal shoes.
