Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates primarily to athletic shoes suitable for track and field events, and relates to soles that are extremely rigid and have good abrasion resistance.

<Prior art> The sole is molded from the same material as the sole of conventional athletic shoes, for example, a relatively hard material such as nylon or polyurethane resin, and the sole is made of the same material as the sole of conventional athletic shoes, and the sole is made of a relatively hard material such as nylon or polyurethane resin, and the sole is made of the same material as the sole of conventional athletic shoes. (thick part or contact surface side)
There was one in which the raised part was molded integrally with the sole body.

<Problems to be Solved by the Present Invention> By the way, among the conventional athletic shoes mentioned above, the former athletic shoes are molded of the same material, so if they are made of hard material, they have good wear resistance, and the attachment of each spike is difficult. Or, each spike is firmly attached without the base plate of the spike falling off, but the side of the shoe bends according to the footwork of the shoe wearer (for example, the side of the part directly below each metatarsal phalangeal joint group of the foot of the shoe wearer). However, in order to provide enough flexibility to bend the edges, if the molded material is made of soft material such as nylon or polyurethane resin, When each spike acts on the ground or the like, there is a risk that the attachment will fall off from the embedded part of the spike attachment due to the rebound impact from the ground.

Means for Solving the Problems> In order to overcome the defects of the soles of the conventional athletic shoes described above, the athletic shoes of the present invention are provided with at least each embedded mounting portion of the spike substrate or spike attachment in the sole of the shoe. , and the sole is made by binding the sides excluding these parts and molding them integrally, which may be a defect of conventional athletic shoes. The parts that require flexibility are the combs, which are easy to bend, and the parts where the spikes tend to fall off are the parts that are intended to be firmly fixed.

Embodiment Examples As shown in FIGS. ), ultrafine powder, ultrashort fibers, ultrafine plate-like substances, or mixtures of 14 or more of these mixtures, etc., with capacitances whose edges are covered with thermoplastic resin except for each attachment point position). First, into the cavity of the mold, a fluid of thermoplastic resin for forming the super steel body part (2) is injected or injected, and then ultrafine powder is poured into the mold to form the super steel body part (1). , a fluid of an ultra-short dense fiber or an ultra-fine plate material, or a mixture of 5 to 20 parts of li or more of these and a thermoplastic resin of 95 to 80 parts, is added to the spike fitting ( 4)
, or by injecting or injecting the substrate of the spike (3) (into the cavity corresponding to the paulownia attachment part) around the spike fitting (4), etc. to each spike (3) and each ultra-steel body part (l). 8 and the rigid body part (2) can be integrally molded and combined 1. In this case, the above-mentioned ultrafine powder desirably has a particle diameter of 7 or 1.
~211 m, and includes fume-based oxides such as alumina, silicic acid, zirconia, and titanium oxide, calcium carbonate, silicon carbide, titanium carbide, boron carbide, boron nitride, titanium nitride, carbon nitride, and carbon boride. , ultrafine compounds such as silicon boride, titanium boride, etc., alkaline earth salts of titanates such as magnesium titanate, potassium titanate, titanic acid, magnesium, etc. Similarly, ultra-short fibers with a length of 1 to 100 prn
% diameter 0.01-0.5pm, asbestos ratio 10-100
, preferably 20 to 300, and examples thereof include boron fibers, potassium titanate fibers, alumina, wolthnite, ferrite derivatives, zinc oxide, metal fibers, and the like. The ultrafine plate-like material has a thickness of 0.01 to 1/Im,
It is a plate-like substance with a length of 1 to 2 pm, and examples thereof include clay minerals and micas. One type or a mixture of two or more of these can be used.

Effects> The athletic shoes of the present invention, as shown in FIGS. 2 I and 3 and FIGS. Spike (81
Since the threaded part (the attachment (4) connected with the penetrating part or the base of the spike (3) is embedded in the aforementioned layer lateral body part (1), each of said spikes (3) can be attached to the ground or When an anti-slip effect is exerted on an all-weather paving material made of a rubber-like elastic material, the super steel body portion (1) is damaged or abraded due to the strong reaction of the ground, etc. and/or the contact friction force, resulting in each spike. (3) can be firmly held without causing the spikes (3) to fall off. Also, except for the spike attachment part (a) on the front side of the sole (a), the parts are made of nylon. 11 or nylon 12
Or, because it is molded from a strong and turbid material such as polyurethane resin, it can be used as the upper cover (b) of athletic shoes.
The curved surface of the bottom surface of the ) part) not only can be easily bent so as to be easily attached to the bottom surface of the shoe, but also can be easily bent to adapt to the movement of the landing part of the heel according to the footwork of the shoe wearer. In particular, the ultra-short θ・5 fibers used to form each super steel body part (1) have a length of 1 to 1 pm and a diameter of 0.01 to 8 pm. Since it is made of solid wood, it is distributed even to the sharp edges of the stem, so the outer surface is smooth and glossy, giving it a good appearance, as well as being rigid and wear-resistant even at sharp ends. In addition, since it has good heat resistance, when running, the contact surface of the sole (a) will not lose its wear resistance or interlaminar properties even if the contact surface of the sole (a) is exposed to the heat generated by repeated impacts or contact friction with the ground etc. There is no.

In addition, in the present invention, when molding each ultra-steel body part (1) and/or rational body part (2), plasticizers, vulcanizing agents, fluidity modifiers, colorants, dispersants, etc., which are normally used, are used as necessary. Any additives can be used in combination.

The surface treatment of the ultrafine powder, ultrashort fibers, and fine plate-like materials used in the present invention is well compatible with thermoplastic resins even under commonly used surface treatment agents.

Implementation method> As shown in the sole (a) shown in FIG. Forming the body part (1) K
As shown in Figure 1 m to ■, etc., each attachment part position) and each protrusion (b) at the center of the heel, or each attachment part (a) and each attachment part pi) Each side edge of the sole (a)); Only the national road e9, g1) or each attachment site pi) and the national road (from each attachment site to each side edge of the sole (a)
c), (c) and the prefectural road (c), e→ part 0) and the prefectural road (c), (c) and Of the metropolitan road (→, (c)), only the circumference (home) that connects with the outer edge of the road (→, (c)) and extends through the unstepped part to the heel part, and each protrusion (b) in the center of the heel part, etc. (c) can also be a rigid body part (1).In this case, the road (c), ? from each attachment site (p) to each side edge of the sole (a). 9 is designed to withstand pressure tζ such as the weight of the shoe wearer who is particularly strongly loaded.
Not only does this contribute to the slippage caused by the movement of the landing part of the shoe wearer due to the constant flow of footwork, but also the reaction of the ground, etc. at that time causes these on the sole (a) of the shoe. It can be reinforced to prevent parts from being worn out or damaged.

Therefore, the athletic shoes of the present invention can be provided as athletic shoes with spikes that are extremely suitable for use mainly in long-distance competitions, hurdle races, and jumping events in track and field events.

In addition, all of the above-mentioned embodiments are super-bonded in athletic shoes, but in addition to this embodiment, a cavity in the shape of a rigid body portion (2) is formed on the bottom side of the upper (b), and the cavity is Nylon 11 or nylon 1 inside

It is also possible to manufacture athletic shoes in which a sole (a) provided with 1) etc. is integrally joined to the bottom side of the upper (b).
