[Prior Art]

 2. Description of the Related Art Conventionally, there have been shoe soles for sports shoes for soccer, rugby, and baseball in which, for example, a stud and a sole body are integrally formed of hard rubber. However, this type of ground has the advantage of being excellent in wear resistance due to the material properties of hard rubber in a ground with severe undulations, and in particular, it has the advantage that the service life of the stud can be maintained for a long time. Due to its poor resilience and flex resistance, it was difficult to transmit the instantaneous force of the sole of the shoe wearer to the sole of the shoe, and the strong kick force could not be effectively utilized. In addition, the sole of the shoe tends to be twisted or flexed due to the intense movement of the foot of the shoe wearer in the shoe upper, which is poor in stability and lacks in lightness. On the other hand, there is one in which the stud and the sole body are integrally formed of a thermoplastic resin such as polyurethane. However, in this type, due to the material properties of polyurethane resin, it is more rigid than the above-mentioned hard rubber, and is superior in impact resilience and flex resistance, but it is wear resistant and shock absorbing. There was a flaw that it was less powerful. Therefore, in particular, the studs that come into direct contact with the ground wear early, and the service life cannot be maintained for a long time.In addition, the sole of the shoe sole cannot provide sufficient shock absorption, leading to premature foot fatigue. It was

[Problems to be solved by the device]

 Therefore, it is a technical object of the present invention to provide a shoe sole having excellent wear resistance and excellent impact relaxation in order to overcome the above-mentioned defects of the conventional shoe sole.

[0004]

[Means for Solving the Problems] In order to solve the above problems, the inventors of the present invention have made earnest studies, and as a result, have provided a device having the following structure. That is, the present invention is a shoe sole having a plurality of studs projecting on the grounding surface side. The sole comprises a stud and a rubber base whose base is integrally formed of hard rubber, and a thermoplastic resin. A shoe sole having a novel structure in which at least the base portion of the rubber base is covered with the base portion.

[0005]

[Action]

 Therefore, according to the present invention, the stud projecting on the sole of the shoe sole and the base portion on which the stud are raised are integrally formed by the hard rubber, so that the material characteristics of the hard rubber can be effectively utilized. By providing a sole with studs with excellent wear resistance, and by forming the base part that covers the base part with a thermoplastic resin, the instantaneous force of the sole of the shoe wearer can be effectively applied to the sole. It can be transmitted and a strong kick force can be exerted. In addition, even when the shoe wearer's foot moves inside the shoe instep, the bottom of the shoe is less likely to be twisted or flexed, and stability is improved when the shoe is worn. Since the structure is covered with the stud, the binding force between the two is strong, and the stud's ability to hold the ground is enhanced.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The present invention comprises a stud 2 and a base portion 3 integrally formed of hard rubber with a rubber base 4 and a base portion 5 made of a thermoplastic resin, and at least the base portion 5 is The base portion 3 of the rubber base 4 is covered, and the base portion 3 is arranged and formed so as to be a lower layer of the base portion 5.

At this time, the hard rubber material used as the base portion 4 is styrene-butadiene rubber, isoprene rubber, acrylic rubber, ethylene. Propylene rubber, chloroprene rubber, acrylonitrile butadiene rubber, butadiene rubber, etc. are used. Considering the wear resistance of the stud 2 and the base part 3, the hardness is set to about 50 to 100 degrees as measured by JISk6301-A. To be done. Next, the base portion 5 is made of polyurethane and a thermoplastic resin such as vinyl chloride, nylon, polyethylene, ABS resin, etc., according to JISk-7215-A. A D-type hardness tester having a hardness of about 50 to 100 degrees is applied.

Next, as the manufacturing method of the present invention, as shown in FIG. 1, a method in which the respective parts of the rubber base 4 and the base 5, which are formed in advance by a mold, are bonded to each other by an adhesive, As shown in FIG. 4, after the rubber base 4 is housed in the mold, there is a method of injecting and molding the resin that will become the base part 5, and any method may be appropriately selected and molded. ..

Next, FIGS. 5 to 7 show an embodiment of a rubber base 4 formed by a stud 2 and a base portion 3 thereof. The embodiment shown in FIG. 5 has a size that covers the entire surface of the shoe sole. , A rubber base 4 is formed in the shape. When the rubber base 4 is formed in this manner, the base 5 is arranged above the base 3 of the rubber base 4 when molding the shoe sole. Further, in the case where the rubber base is formed in the mode in which the space portion 8 is partially provided as shown in FIG. 6, the base portion 5 is arranged on the upper and lower layers of the base portion 3 of the rubber base 4, That is, the rubber base 4 is embedded in the base portion 5, and the bonding force between the two is increased. Further, in FIG. 8, the rubber base 4 is further separated and the area of the base is reduced to the necessary minimum. In this way, the stability of the stud 2 itself is slightly inferior, but there is an advantage that the weight reduction can be promoted.

Next, FIGS. 9 to 11 show a reinforcing plate 6 which reinforces the upper surface of the base portion 5. The reinforcing plate 6 is a small portion of the base peripheral edge 7 of the stud 2 on the base portion 5. At least, it is formed so as to surround and extend a part. That is, the reinforcing plate 6 covers all or part of the base peripheral edge 7 of the stud 2 in order to improve the support force of the stud 2 and to make the impact resilience of the shoe sole more effective. At this time, as shown in FIG. 9, for example, the reinforcing plate 6 becomes a boundary line between the parts of the reinforcing plate 6 at a position along the metatarsal joint so as not to hinder the bending motion of the foot of the reinforcing plate 6. Therefore, it is effective to form them as described above, or to provide the ball of the foot where the landing pressure is easily applied, as shown in FIG. Next, FIG. 11 shows a structure in which the reinforcing plates 6 are integrally extended and side wall portions 9 are formed on the left and right side surfaces of the heel portion. In this way, the reinforcement plate 6 holds the heel portion of the shoe. It is possible to eliminate blurring, prevent so-called excessive pronation of a shoe wearer, and prevent injuries such as sprains and the like due to excessive pronation. At this time, the reinforcing plate 6 is made of a thermoplastic resin such as polyurethane as in the base portion 5 and is made of JIS. D type. An A type hardness tester having a hardness of 50 to 100 degrees is used. Of course, the reinforcing plate 6 is not limited to this, and nylon, vinyl chloride or the like may be used. Further, the reinforcing plate 6 can be provided with a novel design by making its color different from that of the base portion 5 and the rubber base 4. The reinforcing plate 6 is not limited to the one shown in the drawings, and may have any suitable shape. Further, as a method of attaching the reinforcing plate 6 to the base portion 5, there is a method of bonding with an adhesive or a method of injection-molding the base portion 5 previously put in a mold by injection.

[Effect of the device]

 Therefore, according to the present invention, the stud protruding from the sole of the shoe sole and the base portion on which the stud are raised are integrally formed of hard rubber and are covered with the base portion made of a thermoplastic resin. Since the studs that act on the ground effectively wear out due to the material properties of the hard rubber and maintain its useful life for a long time, the base part made of thermoplastic resin such as polyurethane is used for the shoes. The momentary force of the wearer's sole can be transmitted to the sole of the shoe to exert a strong kick force. In addition, even if the shoe wearer's foot moves within the shoe upper, the sole is unlikely to be twisted or bent, and the base portion supporting the stud is completely covered by the base portion. It has a strong binding force and is effective in increasing the ground holding force of the stud. The reinforcing plate covers the base side of the stud 2 to give the supporting force of the stud 2 and the impact resilience of the shoe sole, and the reinforcing plate 6 is integrally projected on both left and right side surfaces of the heel portion. As a result, the heel portion of the shoe can be held to eliminate blurring, prevent so-called excessive pronation of the wearer of the shoe, and prevent sprains and other injuries due to excessive pronation.

As described above, the present invention is an extremely highly practical device as sports shoes for soccer, rugby, and baseball.
