Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attachment structure for a cleat for sports shoes that is replaceably attached to the sole of a sports shoe such as a golf shoe used on grass.

[0002]

2. Description of the Related Art So-called metal spikes with a single metal spike pin, which have been used in golf shoes for a long time, tend to damage the grass of the green, and the damage of the green grass becomes serious with the increase in the number of golfers. , Maintenance is difficult. In recent years, resin cleats, so-called soft spikes, have been used more and more in order to protect green grass and improve comfort.

In such a resin cleat (soft spike), generally, a cleat body having a plurality of anti-slip projections provided on the peripheral edge of the seat plate-like base portion on the grounding surface side is molded from a synthetic resin material, The cleat body has a structure in which a metal mounting screw is insert-molded and integrated into the seat plate-shaped base portion, and the mounting screw is screwed to a female screw body arranged on the sole of the shoe and replaced. It is mounted so that it can be mounted (for example, JP-A-11-225806, JP-A-11-225806).
262401).

However, when the conventional resin cleat (soft spike) is mounted on the sole of the shoe, if the mounting screw is strongly tightened, the mounting screw of the mounting screw is attached to the seat plate-shaped base portion that abuts on the sole. Since the cleat body is deformed by the head's indentation, the cleat cannot be tightened with an excessively large force, and as a result, there is a problem in that the screw loosens during use and the cleat easily falls off the sole.

Particularly, in the case of a resin cleat whose cleat body is molded of a rubber-like elastic material such as urethane resin, the anti-slip protrusions, which are elastically deformed during use, have a large grip force, and have excellent anti-slip function and wear resistance. However, due to the elastic deformation of the anti-slip protrusions, a torque is generated in the direction to loosen the cleat, so that the cleat becomes easier to loosen and often falls off the sole during use.

On the other hand, a cleat body made of synthetic resin and a mounting screw (bolt) made of metal or hard resin are separately formed, and the cleat body is mounted in a through hole formed at the center of a seat plate-shaped base portion. A resin cleat (soft spike) that inserts a special screw and is screwed to an internal thread body arranged on the sole
For the mounting structure of, for example, Japanese Patent Laid-Open No. 2000-992.
No. 05, JP 2000-189212 A, and the like.

However, in the resin cleat (soft spike) consisting of the above-mentioned two members, the head of the mounting screw (bolt) is engaged with the cleat body, and when the cleat is mounted on the sole, the cleat is used. It has a structure in which the main body rotates together with the mounting screws (bolts). Therefore, since the torque acting on the cleat body in the direction of loosening the screw during use is directly applied to the mounting screw, the cleat during use is used in the same manner as the resin cleat in which the cleat body and the mounting screw are integrated. The problem of loosening and falling off has not been solved.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and is particularly due to elastic deformation of a resin cleat whose cleat body is molded of a rubber-like elastic material such as urethane resin. The cleat for sports shoes can be attached to the sole by tightening the cleat body strongly while maintaining a large grip, excellent anti-slip function and wear resistance, and effectively preventing cleat from falling off. It is intended to provide a structure.

[0009]

In order to achieve the above object, the cleat mounting structure of the present invention has a plurality of anti-slip projections on the peripheral edge portion of the seat plate-like base portion on the grounding surface side, and the cleat mounting portion on the center portion. A cleat body for sports shoes, comprising a cleat body having a through hole, and a headed screw which is inserted into the through hole and screwed into an internal thread body disposed on the shoe sole, wherein the cleat body is rubber-like. The head screw is inserted into the through hole through a large-diameter washer that is formed of an elastic material and covers the ground surface side portion of the seat plate-shaped base portion excluding the anti-slip protrusions. The cleat body is attached to the shoe sole.

With the above structure, the cleat body can be firmly tightened with the head screw through the washer to be attached to the shoe sole, and the slack torque applied to the cleat body can be directly applied to the head. Since it does not act on the attached screw, the cleat is effectively prevented from falling off. Moreover, the grip force, the anti-slip function, and the wear resistance due to the elastic deformation of the anti-slip protrusions are effectively maintained.

The washer is made of, for example, a metal material such as carbon steel or aluminum alloy, a hard nylon resin, a fiber-reinforced reinforced resin (FRP), or a ceramic material.

The washer may be fixedly held by engaging with a seat plate-shaped base portion of the cleat body.

It is preferable that the washer is rotatably installed under the neck of the head screw. Further, when the washer rotatably assembled under the head screw is engaged with and fixedly held by the seat plate-shaped base portion of the cleat body, the cleat body, the washer and the head screw are integrated. In addition, since the head screw can be rotated with respect to the cleat body, it is convenient for the cleat mounting and dismounting work.

Further, it is preferable that the washer has a projecting piece which is engaged with the anti-slip projections and extends in a radial direction on an outer peripheral portion thereof. Furthermore, the protrusion is provided with a detent protrusion that protrudes toward the seating surface side of the seat plate base portion, so that the protrusion engages with the sole of the shoe during mounting to prevent the seat plate base portion from rotating. With this configuration, the torque in the loosening direction due to the elastic deformation of the anti-slip protrusion provided on the cleat body is blocked by the protrusion, and the cleat can be effectively prevented from falling off due to slack. In addition, when the shoe sole is provided with a locking hole with which the protrusion is engaged, the function of preventing the seat plate-shaped base portion from rotating during mounting becomes more reliable.

Further, since the cleat is mounted on the shoe sole by rotating only the head screw without rotating the cleat body, the outer shape of the seat plate-shaped base portion of the cleat body is non-circular, and By providing the shoe sole with an engaging portion corresponding to the outer shape of the base portion, the seat plate-shaped base portion can have a rotation preventing function.
