Description

Detailed Description of the Invention (Industrial Application Field) Sole This invention relates to a spiked shoe for sports shoes that protects a mounting base embedded in the sole or main body and facilitates replacement when other mounting structure parts are damaged. Regarding.

(Conventional technology) Sports shoes for baseball, soccer, rugby, etc.
Spikes such as spikes or studs are attached to the bottom of the shoe.

For example, in soccer shoes, as shown in Figure 9,
A synthetic resin stud 62 is fixed to the head 61 of a metal mounting bolt 60, and a nut portion of a metal mounting board 65 is provided with a nut portion in an insertion hole 64 provided in an outsole 63 that constitutes the bottom of the shoe. is inserted into the board to fix it by biting into it,
The bolt 60 of a stud 62 having a metal mounting bolt 60 fixed to the nut portion is detachably fixed. In addition, in baseball shoes, as shown in FIG. 10, a nut part of a metal mounting board 65 provided with a nut part is inserted into an insertion hole 64 provided in the outsole 63, and the board is bitten and fixed. The mounting bolt 60 is removably screwed into the nut portion with a spike interposed therebetween, and the spike 66 is attached to the sole 63.
I was trying to make it stick to it.

Furthermore, as shown in FIG. 11, there is a method in which a mounting base 67 is formed of a synthetic resin material, which is embedded and fixed in the outsole 63, and a spike is mounted by screwing a mounting bolt 60 into the nut portion of the base 67. Ta.

(Problem to be Solved by the Invention) In the above-mentioned spiked shoes, the spike mounting board is directly fixed by providing a nut insertion hole in the sole of the bottom of the shoe, since the nut insertion hole is open. The strength of the outsole decreases. In particular, when shoes are worn, a strong ground impact is applied to the spikes, and this impact presses the bottom of the fixing area of the mounting board, pushing up the mounting board, and at the same time, a large stress is placed on the mounting bolts and nuts of the mounting board. As a result, there were problems such as the mounting bolts being damaged and becoming loose, and the nuts of the mounting board deforming and tearing.

Damaged mounting bolts can be easily replaced or replaced, but damage to the nuts on the mounting board requires the entire mounting board to be removed from the bottom, which not only makes the work complicated, but also damages the bottom and reduces its durability. There was a drawback.

In addition, the impact of the spikes on the ground causes an upward force to act on the mounting board, making the soles of the feet feel uncomfortable and causing pain to the soles of the feet when worn for a long period of time.

In this regard, in the structure shown in FIG. 11, since the mounting base 67 and the outsole 63 are integrated, the feeling of wearing is generally good and there is little risk of hurting the soles of the feet. The nut may be damaged. If the nut part were damaged, the outsole itself had to be replaced, which was a major drawback.

In view of these drawbacks, the object of the present invention is to provide spiked shoes for sports shoes that protect the mounting base of the spikes, facilitate the replacement of other parts of the spiked shoes, have a good feel when worn, and have excellent durability. .

(Means for Solving the Problems) The spike shoes of the sports shoes according to the present invention include spikes in a desired part of the outsole made of an arbitrary material constituting the bottom of the shoe.
A synthetic resin sole of any shape is embedded with a mounting base having a flange and a nut made of any material, and a separate joint nut made of any material is removably screwed onto the nut. There is a patent that features spikes that are removably fixed with mounting bolts.

In addition, a mounting base having a flange and a nut made of any material is directly buried in a desired part of the synthetic resin or synthetic rubber outsole that constitutes the bottom of the shoe, and a separate joint nut made of any material is inserted into the nut. is removably screwed onto the joint nut, and a spike is removably fixed to the joint nut with a mounting bolt.

In addition, a flange and a nut insertion hole made of any material are provided in a desired part of the outsole made of any material constituting the bottom of the shoe, and a separate joint nut made of any material is fitted and fixed into the nut insertion hole as a mounting base. It is characterized in that a buried synthetic resin sole of any shape is integrally joined and fixed, and a spike is removably fixed to the joint nut with a mounting bolt.

In addition, a flange nut insertion hole is provided in a desired part of the outsole made of any material that constitutes the bottom of the shoe, and a separate joint nut made of any material is fitted and fixed into the nut insertion hole as a mounting base. It is characterized in that it is directly buried and a spike is removably fixed to the joint nut with a mounting bolt.

The mounting base and the separate joint nut of the present invention may be made of the same material, but it is preferable that the mounting base be made of synthetic resin and the separate joint nut made of metal, or the opposite. .

Then, set the inner diameter and thread groove of the separate joint nut that hinges to the nut part of the mounting base or the separate joint nut that fits and secures into the nut insertion hole of the mounting base to the same dimensions as conventional spike mounting. Being able to use bolts allows for compatibility between the old and new versions, which is convenient.

In addition, it is preferable that the spikes that are fixed to the outsole of the shoe be integrally molded with the mounting bolts, or that the mounting bolts be embedded and fixed, but it is preferable that the spikes and the mounting bolts be provided separately and screwed together. Good too.

Further, it is preferable that a separate joint nut screwed onto the nut portion of the mounting base is provided with a fitting hole into which the mounting tool is fitted.

(Function) In the sports shoes of the present invention, the strong impact force that acts on the spikes during exercise acts on the spikes, the mounting bolt, the joint nut, the nut portion of the mounting base, or the nut insertion hole in this order.

Therefore, if a large impact force is applied or depending on the frequency of use, any of the above will be damaged, but if the spikes, mounting bolts, or joint nuts are damaged, it is easy to replace them, but the nut on the mounting base If the nut insertion hole is damaged, the sole or outsole itself must be replaced because the mounting base is embedded in the sole or outsole.

However, in this invention, a mounting base having a flange portion and a nut portion or a flange portion and a nut insertion hole is buried in the sole or in the outsole, and when buried in the sole, the sole is integrally connected to the outsole. Moreover, a separate joint nut is fitted and fixed in the nut portion of the mounting base or the nut insertion hole of the mounting base to form a single layer. Since the mounting base is firmly buried in the sole or outsole with the anchoring effect of the flange, it is almost never peeled off or damaged by the impact of the spikes, and the thrusting effect of the spikes is reduced. .

In particular, the nut portion or the nut insertion hole of the mounting base is double reinforced with a separate joint nut, and
Since the surface area of the eye becomes larger, the area of contact with the fixing spike inevitably becomes larger, making the spike more stable and increasing the fixing force of the mounting bolt. Therefore, when a strong impact force is applied to the spikes, the impact force is diffused and attenuated by the sole or outsole, and the transmission to the mounting bolt is relaxed and reaches the nut part of the mounting base or the joint nut of the S/Y insertion hole. It has the effect of significantly attenuating impact force.

If excessive impact force is applied to the joint nut, the joint nut may be deformed or damaged! Absorbs impact force and reduces damage to the nut part of the mounting base or the nut insertion hole.
It has the effect of preventing.

The means for embedding the mounting base 4 in the sole 5 described in the above embodiments may be carried out by injection molding or other known methods, and the method for integrating the sole 5 with the outsole 1 may also be carried out by adhesion, injection molding or other known methods. In addition, the method of embedding the mounting base 4 in the outsole 1 can also be carried out at the same time when the outsole 1 is molded by injection molding or other known methods.

Furthermore, the joystick nut 6 which is separate from the mounting base 4 described in the above embodiments is not limited to the materials shown in the embodiments, such as a same synthetic resin material, a different synthetic resin material, a metal material, or a combination thereof. Therefore, suitable materials can be selected as appropriate.

(Effects of the Invention) In the spike shoes of the present invention, since the mounting base has a flange that acts as an anchor and is embedded in the sole or outsole,
It is possible to prevent the mounting base from peeling off or being damaged due to the impact received from the spikes.

In particular, a separate joint nut is screwed or fixed to the nut part or nut insertion hole of the mounting base, so it can be reinforced double, and the surface area of the eye part that comes into contact with the spike is equivalent to the joint nut. It is wider and has more contact area with the fixed spike, making the spike more stable.As a result, the fixing force of the mounting bolt also increases, which has the effect of attenuating the impact force from the spike by diffusing it to the sole or outsole. However, since the impact force transmitted to the mounting bolt becomes weaker and the remaining impact is absorbed by the joint nut, the risk of damaging the nut portion or the nut insertion hole of the mounting base is significantly reduced. If excessive impact force is applied to the spikes,
Acts on the joint nut of the mounting base, the nut portion of the mounting base, or the nut insertion hole through the mounting bolt. At this time, the joint nut first undergoes deformation, tearing, etc. due to the impact force, thereby alleviating the impact force, and the impact force on the nut portion of the mounting base or the nut insertion hole becomes weak.

Therefore, damage to the mounting base is almost eliminated, and the durability of the shoe is increased.

In addition, if the joyseat nut is to be replaced due to deformation, tearing, etc., the work is easy and will not damage the sole or outsole. In general, in the spike shoes of this invention, the mounting base is buried in the sole or outsole, so even if the ground surface is uneven, the inner surface of the shoe sole is finished flat, making it suitable for use with cushioning materials and insoles. In particular, when the mounting base is buried in one part of the sole and the sole is joined and integrally fixed to a desired part of the outsole, the bottom of the shoe in that part becomes thick and the spikes push up. can be further prevented,
There is no risk of hurting the soles of the feet, and the shoe feels good when worn.

It is effective when applied to soccer shoes, lug shoes, baseball/softball shoes, and other sports shoes with spikes.
