Description

[Detailed description of the invention] This invention uses a structure with an elastic effect and an air cushion effect to prevent slipping and
It reduces sprains caused by falls and prevents fatigue even when worn for long periods of time.Furthermore, each person has a different foot shape, and it wraps around the feet of each person. This relates to the improvement of footwear in general, such as just-fitting shoes (including athletic shoes) and sandals.

In the past, various improvements have been made to prevent sprains, wearability, and fatigue by using lightweight sponges, foamed urethane, etc., but there are problems with their structure and shape, and shoes (including athletic shoes), At present, no solutions have been found for sandals and other footwear in general.

This idea uses a structure with a hollow hole, focusing on foot pressure distribution (Figure 4) based on foot pressure measurement, which is considered from an ergonomic perspective in terms of sprains, wearability, and fatigue. These shoes are designed to further eliminate the To explain this invention based on the drawings, 1 is a structure obtained by molding polyvinyl chloride, polyurethane, thermoplastic rubber, and cellular synthetic resin, 1 is for the inner part (Fig. 1), and 2 is the outer sole (Fig. 1). 2 and 3), this structure is provided with a hollow hole 1 as shown in FIG. The diameter of the hollow holes 1 is 8 mm±3 mm, and the upper portions of the hollow holes 1 are connected by grooves 4 whose width is narrower than the diameter of the hollow holes 1.

By making the upper hole diameter smaller than the lower hole diameter, a more appropriate elastic effect and air cushion effect can be obtained, and it is also possible to prevent the midsole material from deforming (falling down) due to the weight load when wearing the shoe.

The structure for the inner material b as 1 can be actually used in shoes, and is formed to have a thickness in the range of 5 mm to 10 mm so that shoes with good bounce can be obtained. The thickness used for the sole is 8 mm to 16 mm overall, and the depth of the hollow hole is 5 mm to 10 mm, so that the thickness range can be freely set depending on the shoe design and the idea at the time. It is shaped with consideration to good return. The materials of this molded structure, such as polyvinyl chloride, polyurethane, thermoplastic rubber, and cellular synthetic resin, have the best elasticity and air cushioning effects when the hardness is between 50°C and 70°C. Structures molded outside the range of 50°C to 70°C will not only be too soft to deform, have no elasticity, and will not have air cushioning effects.
This will increase the feeling of fatigue when walking. In addition, if it is too hard, the elastic effect and air cushion effect will not be obtained, resulting in poor bounce and increasing fatigue. This is considered to be the optimal condition for The best elastic effect and air cushion effect can be obtained with the same structure and shape.
This idea was designed to provide even greater elasticity and air cushioning effects. In other words, we place the utmost importance on the foot pressure distribution (Figure 4) based on foot pressure measurement, which is considered from ergonomics, in addition to the structure of the hollow hole 1, thickness, and material described so far, which is used as the inner sole and outsole. By utilizing this foot pressure area (Figure 4) on the inside (Figure 1) and outsole (Figures 2 and 3), the order of contact with the ground due to the movement of foot pressure during walking and the pressing force were taken into consideration. Hollow holes 1 are distributed densely and sparsely in each part of the heel, stepping part, and toe, and the hollow holes 1
They have a structural form in which they are connected to each other by grooves 4.

The hollow holes 1 arranged in the heel, tread, and toe areas are arranged differently depending on the intended use of the shoe, for example, business shoes, casual shoes, and athletic shoes. As shown, hollow holes 2 and 3 of different diameters are arranged in each part of the heel, tread, and toe, and as shown in Figure 2, hollow holes of the same diameter are arranged. The shoes are designed to have a shape and structure that can be used depending on the intended use of the shoe, with appropriate consideration given to the shoes, such as those that are flat or are provided with a no-stepping part clearance structure 7.

To give an example of how this structure is used as an outsole, it can be bonded to an adhesive shoe as an outsole using a conventional adhesion method as shown in FIG. In addition, to give an example of how to use it as a filling, as shown in Figure 6, by inserting the structure of this invention into the filling part of the conventional Gutsdoyer manufacturing method (JIS S 5050), it can be used in the conventional Gutsdoyer manufacturing method. You can. As described above, this structure has a wide range of applications, including both bonded shoes and sewn shoes, and can be used in various manufacturing methods. In addition, the surface of the outsole is made of anti-slip material that is commonly used to prevent fractures,
In order to reduce accidents such as sprains, the effect can be doubled as an integrated structure with the structure and the upper part 12.

Appropriate use of the material of the structure, appropriate hardness molded under optimal conditions, the shape of the hollow hole 1 with a wide range of applications, and the structure in which the hollow holes 1, 2, and 3 are connected with the groove 4, the upper part These shoes have a one-piece structure that is glued or sewn together, so they exhibit the following functions.

The ground surface is equipped with a non-slip material that is normally used to prevent slipping, and because this structure is used, you can walk safely even in the rain or with water dripping, preventing fractures, sprains, etc. can protect your body from accidents. What is particularly emphasized is the foot pressure distribution based on foot pressure measurement based on ergonomic considerations (Figure 4), which perfectly captures the foot pressure that accompanies the movement of the body's center of gravity during walking, and is tailored to the human walking function. Because these shoes have a solid structure, if there are obstacles such as uneven surfaces or stones on the ground, the elastic effect and air cushion effect work together to accurately grasp the situation on the ground and always respond accurately to the situation. I can do it. As a result, you can walk safely, protecting your body from foot accidents such as fractures and sprains, increasing your walking function, and wrapping your feet in just the right fit so you don't feel fatigued even when walking for long periods of time. These are durable shoes with maximum functionality never seen before.
