Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to sports shoes provided with a projection for ball control.

Conventionally, as a shoe for soccer or football, a sports shoe has been proposed in which a large number of resin projections for ball control are provided on the outer surface of the instep (see, for example, Japanese Examined Patent Publication No. 63-13681). (See Hei 1-19883). In these shoes, the protrusion increases the coefficient of friction with the ball, thereby increasing the rotational speed of the ball and changing the curve or the shoot. Therefore, the technique of ball control can be easily learned.

[0003]

However, in the above-mentioned prior art, since the protrusion is provided only on the front foot portion of the shoe,
No consideration is given to back passes in soccer.

Further, in a competition in which kick, run, stop and turn are repeated for a long time such as soccer or football, foot fatigue becomes great, so it is extremely important to make the shoes lightweight. Further, in order to perform accurate ball control, it is preferable that the feet are well aligned and the entire instep fits the feet.

[0005] However, when a material that fits well on the foot and is lightweight is used for the instep, since such a material generally has low durability and wear resistance, the material of the instep is deteriorated by kicking or sliding. Because of its ease, it has not been possible to use such materials for sports shoes with conventional technology.

Therefore, an object of the present invention is to provide a sports shoe having resin protrusions for ball control, which is lightweight and fits well on the foot, and is excellent in durability and wear resistance, and also in terms of back path. It is to provide sports shoes that are easy to control.

[0007]

In order to achieve the above object, the present invention provides a large number of projections on the forefoot and heel of the instep, and a suede-like composite in which the outer surface of the instep is raised. It is composed of non-woven fabric made of fibers. The protrusion of the present invention is made of synthetic resin, synthetic rubber, natural rubber, or the like.

According to the present invention, since the outer surface of the instep is made of a raised suede-like non-woven fabric, the instep is made of a flexible material, so that it is easy to follow the legs and is lightweight. In addition, since a large number of protrusions are provided not only on the forefoot part of the shoe but also on the heel part, it is easy to control the ball even for a backpass by a heel kick. Furthermore, since a large number of protrusions are provided on the forefoot and heel, even if a material that is lightweight and flexible and fits along the foot is used, the portion that is easily damaged by kicks or sliding is protected by the large number of protrusions, so it is sufficient. Excellent wear resistance and durability can be obtained.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment. In FIG. 1, the sports shoes of this embodiment are
A soccer shoe having a large number of spikes 1 fixed to an outer sole 2.

A large number of resin protrusions 4 for ball control are provided on the outer surfaces of the forefoot portion 35 and the heel portion 36 of the instep cover 3 which covers the foot. These resin protrusions 4 are made of, for example, a polyurethane-based synthetic resin, and as shown in FIG. 2, they are formed in two stages, with a fixing portion 40 having a large bottom area and a control portion 41 having a small bottom area.

The outer surface layer (upper layer) of the instep cover 3 is formed of a non-woven fabric 31, and the material of the front foot portion 35 of the instep cover 3 is a woven fabric (back side) made of cotton between the pair of non-woven fabrics 31 and 33. Material) 3
It is formed of a laminated material in which 2 is inserted. The laminated material is
That is, the non-woven fabric 31, the woven fabric 32, and the non-woven fabric 33 are not bonded to each other, but are sewn together by the thread 7 in FIG. The outer surface layer (upper layer) non-woven fabric 31 of FIG. 2 is made of suede-like synthetic fibers having an outer surface 31a raised, while the inner surface layer (lower layer) non-woven fabric 33 is
The inner surface 33a is made of suede-like synthetic fibers with a raised fabric, and is therefore lightweight and highly flexible. The non-woven fabrics 31 and 33 are made of, for example, fibers containing a polyurethane-based synthetic resin, and Exeine (registered trademark) manufactured by Toray Industries, Inc. can be used.

The fixing portion 40 of the resin protrusion 4 is fixed to the instep 3 by impregnating the raised portion 31a of the outer surface non-woven fabric 31 with polyurethane resin.

FIG. 3A shows the insole 5 of the shoe. This insole 5 is arranged along the bottom surface of the foot along the spike 1 of FIG. 3 (b).
It relieves the impact force from. The spike 1 is fixed to the outer bottom 2 and the inner bottom 6 by a screw member 10.
The insole 5 is constructed by laminating a pair of foamed resin layers 52 and 53 under a cloth 51 made of an upper woven cloth. The upper foamed resin layer 52 is made of EVA (ethylene vinyl acetate), for example, while the lower foamed resin layer 53 is made of polyethylene. The lower foamed resin layer 53 has a hardness higher than that of the upper foamed resin layer 52,
That is, the Young's modulus is set to be large. The lower foamed resin layer 53 has a large number of small particles (for example, a diameter of 1
A through hole 53a is formed. The structure of the main insole 5 itself can be applied to sports shoes for baseball having spikes and not having the protrusions 4.

In the above structure, the upper 3 of the present sports shoe is constructed by laminating suede-like non-woven fabrics 31 and 33 whose surfaces are raised on the front and back sides of the woven fabric 32 as shown in FIG. The toe 3 fits easily on the foot, and the shoe becomes lightweight. In particular, the outer surface 31a and the inner surface 33a that are farthest from the neutral axis C of the material of the instep 3 are fluffed, and the fluffed portions have almost no resistance to bending. The bending rigidity of the material is significantly reduced. As a result, the ball fits easily on the foot, which facilitates ball control.

Further, in the present sports shoe, the resin protrusion 4 is provided not only on the forefoot portion 35 of FIG. 1 but also on the heel portion 36. Therefore, the ball control becomes accurate even for the back pass by the heel kick.

Moreover, as described above, since the resin protrusions 4 are provided not only on the forefoot portion 35 but also on the heel portion 36, the instep 3 can be protected from abrasion not only on the kick but also on the sliding. it can. Therefore, as with brushed non-woven fabric, Exaine (registered trademark), which originally has low abrasion resistance,
It is possible to use materials such as, for example, to reduce the weight and improve the fit of the shoes required for soccer shoes.

Further, in this sports shoe, since the outer surface of the instep cover 3 is raised, the raised portion 31a of the instep cover 3 in FIG. 2 is likely to be impregnated with the resin.
Is firmly fixed to the instep cover 3. Moreover, if the resin protrusions 4 and the instep cover 3 contain the same kind of synthetic resin, the affinity between the instep cover 3 and the resin protrusions 4 is good, so that the fixing force becomes large.
Therefore, even if a large impact force is applied, there is no possibility that the resin protrusion 4 will peel off from the instep cover 3.

Further, in this embodiment, the Young's modulus of the lower foamed resin layer 53 of the insole 5 of FIG. 3B is set to be higher than that of the upper foamed resin layer 52. Therefore, the thrust force from the spike 1 is easily dispersed, so that the impact force generated on the sole of the foot is reduced even if the insole 5 is not made thicker.

Further, in this embodiment, since a large number of small through holes 53a are formed in the lower foamed resin layer 53, when the lower foamed resin layer 53 is bonded to the upper foamed resin layer 52, it is possible to reduce Air can be prevented from collecting between the two foamed resin layers 52 and 53.

By the way, in the above embodiment, the resin protrusion 4 of FIG. 1 is provided only on the forefoot portion 35 and the heel portion 36, but in the present invention, as shown in FIGS. 4 and 5, the forefoot portion 35 and the heel portion 36. In addition to the above, the resin protrusion 4 may be provided on the middle foot portion 37 of the instep cover 3. Further, in each of the above embodiments, the spike 1
Although the sports shoes for soccer having the above have been described, the present invention relates to sports shoes for football and
Alternatively, it can be applied to other sports shoes such as running shoes with rubber soles having no spikes as shown in FIG.

[0021]

As described above, according to the present invention,
Since the outer surface of the instep is formed by the raised suede-like non-woven fabric, the instep easily follows the foot and is lightweight. Also, since a large number of protrusions are provided not only on the forefoot part of the shoe but also on the heel part, ball control becomes easy even for a backpass by a heel kick. Furthermore, since a large number of protrusions are provided on the forefoot and heel of the instep, even if it is a lightweight and flexible suede-like material with low wear resistance, the instep protects the instep from damage caused by kicks and sliding. Therefore, it is possible to adopt such a material. In other words, by providing a large number of protrusions not only on the forefoot part of the instep but also on the heel part, not only the control of the backpass but also the freedom of material selection is increased, and ball control and wear resistance, light weight and The fit can be improved at the same time.

Further, in the invention of claim 2, since the material of the forefoot part of the instep is made of a laminated material and the non-woven fabrics raised on the front and back are adopted, the raised parts on the front and back have no resistance to bending. Since it does not exhibit force, the flexural rigidity of the material is significantly reduced, further increasing the fit and weight.

Further, in the third aspect of the invention, since the non-woven fabric and the backing material are sewn to each other without adhering to each other, there is no fear of impairing the flexibility of the material of the front foot portion of the instep cover.

On the other hand, in the invention of claim 4, since the protrusions are fixed to the nonwoven fabric by impregnating the outer surface of the napped nonwoven fabric with the synthetic resin, a large fixing force can be obtained.

According to the invention of claim 5, the insole has three parts.
Since the foamed resin layer of the lower layer is set to have a higher Young's modulus than the foamed resin layer of the upper layer, it is formed in layers, so the impact force generated on the sole of the foot can be softened without making the insole thicker. be able to.

Furthermore, according to the invention of claim 6, since a large number of through holes are formed in the lower foamed resin layer, at the time of manufacturing,
Air can be prevented from collecting between the two foamed resin layers.
